Form and Dating. The Securities and the certificate of authentication, and the notation on the Securities relating to the Guarantee, shall be substantially in the forms of Exhibits A and A-1, respectively. The Securities may also have such insertions, omissions, substitutions and variations as are required or as may be permitted by or consistent with this Indenture. The provisions of Exhibits A and A-1 are part of this Indenture. The Securities may have notations, legends and endorsements required by law or stock exchange rule or usage. The Company shall approve the form of the Securities and any notation, legend or endorsement on them. Each Security shall be dated the date of its authentication. The terms and provisions contained in the Securities and the Guarantee shall constitute, and are hereby expressly made, a part of this Indenture and, to the extent applicable, the Company and the Subsidiary Guarantors, by their execution and delivery of this Indenture, expressly agree to such terms and provisions and to be bound thereby. Securities offered and sold in their initial distribution in reliance on Rule 144A under the Securities Act and other than in reliance on Rule 144A under the Securities Act or Regulation S shall be issued in the form of one or more Global Securities (collectively, and, together with their Successor Securities, the "Restricted Global Security") in fully registered form without interest coupons, substantially in the form of Security set forth in Exhibit A hereto, with such applicable legends as are provided for in Exhibit A except as otherwise permitted herein. Such Restricted Global Security shall be registered in the name of the Depositary or its nominee and deposited with the Trustee, as custodian for the Depositary, duly executed by the Company and authenticated by the Trustee as hereinafter provided, for credit by the Depositary to the respective accounts of beneficial owners of the securities represented thereby (or such other accounts as they may direct). SECTION 2.02. Execution and Authentication. Two Officers of the Company shall sign the Securities on behalf of the Company, and one Officer of each Subsidiary Guarantor shall sign the notation on the Securities relating to the Guarantee of such Subsidiary Guarantor on behalf of such Subsidiary Guarantor, in each case by manual or facsimile signature. The Company's seal shall be reproduced on the Securities. If an Officer of the Company or any Subsidiary Guarantor whose signature is on a Security no longer holds that office at the time such Security is authenticated, such Security shall be valid nevertheless. A Security shall not be valid until the Trustee or an authenticating agent manually signs the certificate of authentication on the Security. The signature shall be conclusive evidence that the Security has been authenticated under this Indenture. The Trustee or an authenticating agent shall authenticate Securities for original issue in the aggregate principal amount of $500,000,000 upon a written order of the Company signed by two Officers of the Company. The aggregate principal amount of Senior Notes outstanding at any time may not exceed $500,000,000. Series B Notes may be issued only in exchange for a like principal amount of Series A Notes pursuant to an Exchange Offer. The principal and interest on Book-Entry Securities shall be payable to the Depositary or its nominee, as the case may be, as the sole registered owner and the sole holder of the Book-Entry Securities represented thereby. The principal and interest on Securities in certificated form shall be payable at the office of the Paying Agent. The Trustee may appoint an authenticating agent to authenticate Securities. An authenticating agent may authenticate Securities whenever the Trustee may do so except on original issuance. Each reference in this Indenture -17- 24 to authentication by the Trustee includes authentication by such agent. An authenticating agent has the same rights as an Agent to deal with the Company or its Affiliates. The Securities shall be issuable only in registered form without coupons and only in denominations of $1,000 and any integral multiple thereof. If the Securities are to be issued in the form of one or more Global Securities, then the Company shall execute and the Trustee shall authenticate and deliver one or more Global Securities that shall represent and shall be in minimum denominations of $1,000. SECTION 2.03. Registrar and Paying Agent. The Company shall maintain an office or agency where the Securities may be presented for registration of transfer or for exchange (the "Registrar") and an office or agency where Securities may be presented for payment (the "Paying Agent"). The Registrar shall keep a register of the Securities and of their transfer and exchange. Where the Trustee is acting as or has been appointed Registrar and/or Paying Agent, the Company may appoint one or more co- registrars and one or more additional paying agents with the prior consent of the Trustee, whose consent shall not be unreasonably withheld. The term "Paying Agent" includes any additional paying agent. The Company shall enter into an appropriate agency agreement with any Agent not a party to this Indenture. Such agency agreement shall provide for reasonable compensation for such services. The agreement shall implement the provisions of this Indenture that relate to such Agent. The Company shall notify the Trustee of the name and address of any such Agent and shall furnish the Trustee with an executed counterpart of any such agency agreement. If the Company fails to maintain or act as Registrar or Paying Agent, the Trustee shall act as such and shall be duly compensated therefor. The Registrar or a co-registrar and a Paying Agent shall be maintained by the Company in the Borough of Manhattan, the City of New York. The Company initially designates the Trustee as the Registrar and Paying Agent. The Company initially appoints The Depositary Trust Company ("DTC") to act as Depositary with respect to the Global Securities. Cede & Co. has been appointed as the nominee of DTC. The Company initially appoints the Trustee to act as the Registrar and Paying Agent and to act as Securities Custodian with respect to the Global Securities. SECTION 2.04. Paying Agent to Hold Money in Trust. The Company shall require each Paying Agent other than the Trustee to hold in trust for the benefit of Holders or the Trustee all money held by such Paying Agent for the payment of principal of, premium, if any, or interest on the Securities (whether such money shall have been paid to it by the Company or any Subsidiary Guarantor), and to notify the Trustee of any Default by the Company or any Subsidiary Guarantor in making any such payment. While any such Default continues, the Trustee may require the Paying Agent to pay all money held by it to the Trustee. Except as provided in the immediately preceding sentence, the Company at any time may require a Paying Agent to pay all money held by it to the Trustee and to account for any funds disbursed and, if the Company requires such payment, the Company shall give prior notice to the Trustee and provide appropriate money transfer instructions to the Paying Agent. Upon such payment over to the Trustee and accounting for any funds disbursed, such Paying Agent (if other than the Company or a Subsidiary) shall have no further liability for the money. If the Company or a Subsidiary acts as Paying Agent, it shall segregate and hold as separate trust funds for the benefit of the Holders all money held by it as Paying Agent. -18- 25 SECTION 2.05. 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 and shall otherwise comply with TIA Section 312(a). If the Trustee is not the Registrar, the Company shall furnish or cause to be furnished to the Trustee at least 10 Business Days prior to each semiannual 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, and the Company shall otherwise comply with TIA Section 312(a). SECTION 2.06. Transfer and Exchange. (a) Exchange of Beneficial Interests in Global Security for Certificated Security. Beneficial interests in a Global Security may, subject to the restrictions on the transferability of the Securities, be exchanged for certificated Securities upon request but only upon at least 20 days' prior written notice given to the Trustee by or on behalf of the Depositary (in accordance with the Depositary's customary procedures) and will bear the applicable legends set forth in Exhibit A hereto. (b) Surrender for Exchange of Global Securities. If any Global Security is to be exchanged for other Securities or canceled in whole, it shall be surrendered by or on behalf of the Depositary or its nominee to the Trustee, as Registrar, for exchange or cancellation as provided in this Article Two. If any Global Security is to be exchanged for other Securities or cancelled in part, or if another Security is to be exchanged in whole or in part for a beneficial interest in any Global Security, such Global Security shall be so surrendered for exchange or cancellation as provided in this Article Two or, if the Trustee is acting as custodian for the Depositary or its nominee (or is party to a similar arrangement) with respect to such Global Security, the principal amount thereof shall be reduced or increased by an amount equal to the portion thereof to be so exchanged or cancelled, or the principal amount of such other Security to be so exchanged for a beneficial interest therein, as the case may be, in each case by means of an appropriate adjustment made on the records of the Trustee, whereupon the Trustee, in accordance with the Applicable Procedures, shall instruct the Depositary or its authorized representatives to make a corresponding adjustment to its records (including by crediting or debiting any Agent Member's account as necessary to reflect any transfer or exchange of a beneficial interest). Upon any such surrender or adjustment of a Global Security, the Trustee shall, subject to this Article Two, authenticate and deliver any Securities issuable in exchange for such Global Security (or any portion thereof) to or upon the order of, and registered in such names as may be directed by, the Depositary or its authorized representative. Upon the request of the Trustee in connection with the occurrence of any of the events specified in the preceding paragraph or in clause (k) below, the Company shall promptly make available to the Trustee a reasonable supply of Securities that are not in the form of Global Securities. The Trustee shall be entitled to rely upon any order, direction or request of the Depositary or its authorized representative which is given or made pursuant to this Article Two if such order, direction or request is given or made in accordance with the Applicable Procedures. (c) Proxies by Registered Holder. Subject to the provisions in the legends required by this Indenture, the registered Holder may grant proxies and otherwise authorize any Person, including Agent Members, and Persons who may hold interests in Agent Members to take any action that such Holder is entitled to take under this Indenture. (d) Interests of Agent Members and Depositary in Global Security. Neither Agent Members nor any other Person on whose behalf Agent Members may act shall have any rights under this Indenture with respect to any Global Security held on their behalf by the Depositary or under the Global Security, and the Depositary may be treated by the Company, the Trustee and any agent of the Company or the Trustee as the absolute owner of such Global Security for all purposes whatsoever. Notwithstanding the foregoing, nothing herein shall prevent the Company, the Trustee or any agent of the Company or the Trustee from giving effect to any written certification, proxy or other authorization furnished by the Depositary or impair, as between the Depositary and its Agent Members, the operation of customary practice governing the exercise of the rights of a Holder of any Security. (e) Transfers of Securities. Upon presentation for transfer and exchange of any Security at the office of the Trustee, as Registrar, located in The City of New York, accompanied by a written instrument of transfer -19- 26 or exchange in the form approved by the Company (it being understood that, until notice to the contrary is given to Holders of Securities, the Company shall be deemed to have approved the form of instrument of transfer or exchange, if any, printed on any Security), executed by the registered Holder, in person or by such Holder's attorney thereunto duly authorized in writing, and upon compliance with this Section 2.06, such Security shall be transferred upon the Register, and a new Security shall be authenticated and issued in the name of the transferee. Notwithstanding any provision to the contrary herein or in the Securities, transfers of a Global Security, in whole or in part, and transfers of interests therein of the kind described in this Section 2.06, shall only be made in accordance with this Section 2.06. Transfers and exchanges subject to this Section 2.06 shall also be subject to the other provisions of this Indenture that are not inconsistent with this Section 2.06. (f) General. A Global Security may not be transferred, in whole or in part, to any Person other than the Depositary or a nominee thereof, and no such transfer to any such other Person may be registered; provided, however, that this clause (f) shall not prohibit any transfer of a Security that is issued in exchange for a Global Security but is not itself a Global Security. No transfer of a Security to any Person shall be effective under this Indenture or the Securities unless and until such Security has been registered in the name of such Person. Nothing in this clause (f) shall prohibit or render ineffective any transfer of a beneficial interest in a Global Security effected in accordance with the other provisions of this Section 2.06. (g) Other Exchanges. Securities that are not Global Securities may be exchanged (on transfer or otherwise) for Securities that are not Global Securities or for beneficial interests in a Global Security (if any is then outstanding) only in accordance with such procedures (including the certification requirements intended to insure that transfers of beneficial interests in a Global Security comply with Rule 144A under the Securities Act), as may from time to time be adopted by the Company and the Trustee. (h) Transfers of Certificated Securities. When Securities in certificated form are presented to the Registrar with a request to register the transfer of such Securities or to exchange such Securities for an equal principal amount of Securities of other authorized denominations, the Registrar shall register the transfer or make the exchange as requested if its requirements for such transaction are met; provided, however, that the Securities surrendered for transfer or exchange shall be duly endorsed or accompanied by a written instrument of transfer in form satisfactory to the Company and the Registrar, duly executed by the Holder thereof or its attorney duly authorized in writing. To permit registrations of transfers and exchanges, the Company shall execute and the Trustee shall authenticate Securities at the Registrar's request. No service charge shall be made for any registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any transfer tax or similar governmental charge payable in connection therewith (other than any such transfer taxes or similar governmental charge payable upon exchanges or transfers pursuant to Sections 2.02, 2.10, 3.07 or 9.05). The Registrar shall not be required to register the transfer of or exchange of any Security (i) during a period beginning at the opening of business 15 days before the mailing of a notice of redemption of Securities and ending at the close of business on the day of such mailing and (ii) selected for redemption in whole or in part pursuant to Article Three, except the unredeemed portion of any Security being redeemed in part. (i) Exchange of Certificated Series A Notes for Book-Entry Security. If a Series A Note is a Restricted Security in certificated form, then as provided in this Indenture and subject to the limitations herein set forth, the Holder, provided it is a Qualified Institutional Buyer, may exchange such Security for a Global Security by instructing the Trustee to arrange for such Series A Note to be represented by a beneficial interest in a Global Security in accordance with the customary procedures of the Depositary. (j) Execution and Authentication of Certificated Securities. Upon any exchange provided for in Section 2.06(a), the Company shall execute and the Trustee shall authenticate, and deliver to the person specified by the Depositary a new Series A Note or Notes registered in such names and in such authorized denominations as the Depositary, pursuant to the instructions of the beneficial owner of the Securities requesting the exchange, shall instruct the Trustee. Thereupon, the beneficial ownership of such Global Security shown on the records maintained by the Depositary or its nominee shall be reduced by the amounts so exchanged and an appropriate endorsement be made by and on behalf of the Trustee on the Global Security. Any such exchange shall be effected through the Depositary in accordance with the procedures of the Depositary therefor. -20- 27 (k) Registration of Global Security in Name Other than Depositary. Notwithstanding the foregoing, no Global Security shall be registered for transfer or exchange, or authenticated and delivered, whether pursuant to this Section, Section 2.07, 2.10 or 3.06 or otherwise, in the name of a person other than the Depositary for such Global Security or its nominee until (i) the Depositary notifies the Company that it is unwilling or unable to continue as Depositary for such Global Security or if at any time the Depositary ceases to be a clearing agency registered under the Exchange Act, and a successor depositary is not appointed by the Company within 30 days, (ii) the Company executes and delivers to the Trustee a Company Order that all such Global Securities shall be exchangeable or (iii) there shall have occurred and be continuing an Event of Default. Upon the occurrence in respect of any Global Security representing the Securities of any one or more of the conditions specified in clause (i), (ii) or (iii) of the preceding sentence, such Global Security may be registered for transfer or exchange for Securities registered in the names of, authenticated and delivered to, such persons as the Trustee or the Depositary, as the case may be, shall direct. (l) Delivery of Securities Upon Transfer or Exchange of Global Security. Except as provided above, any Security authenticated and delivered upon registration of transfer of, or in exchange for, or in lieu of, any Global Security, whether pursuant to this Section 2.07, 2.10 or 3.06 or otherwise, shall also be a Global Security and bear the legend specified in footnote 1 to Exhibit A. SECTION 2.07. Replacement Securities. If a mutilated Security is surrendered to the Trustee or if the Holder of a Security claims that the Security has been lost, destroyed or wrongfully taken, the Company shall issue and the Trustee shall authenticate a replacement Security if the requirements of the Trustee are met. An indemnity bond may be required by the Trustee, the Company or any Subsidiary Guarantor that is sufficient in the judgment of the Company, the Subsidiary Guarantors and the Trustee to protect the Company, the Subsidiary Guarantors, the Trustee or any Agent from any loss which any of them may suffer if a Security is replaced. The Company may charge for its expenses (including fees and expenses of the Trustee) in replacing a Security. SECTION 2.08. Outstanding Securities. Securities outstanding at any time are all Securities authenticated by the Trustee except for those canceled by it, those delivered to it for cancellation, those reductions in the interest in a Global Security effected by the Trustee in accordance with the provisions hereof, and those described in this Section 2.08 as not outstanding. Except as set forth in Section 2.09, a Security does not cease to be outstanding because the Company, the Subsidiary Guarantors or any of their respective Subsidiaries or Affiliates holds the Security. If a Security is replaced pursuant to Section 2.07, it ceases to be outstanding unless the Trustee receives proof satisfactory to it that the replaced Securities is held by a bona fide purchaser. If the principal amount of any Security is considered paid under Section 4.01, it ceases to be outstanding and interest on it ceases to accrue. SECTION 2.09. Treasury Securities. In determining whether the Holders of the required principal amount of Securities have concurred in any direction, waiver or consent, Securities owned by the Company, any Subsidiary Guarantor or an Affiliate of the Company shall be considered as though they are not outstanding, except that for the purposes of determining whether the Trustee shall be protected in relying on any such direction, waiver or consent, only Securities which the Trustee knows are so owned shall be so disregarded. -21- 28 SECTION 2.10. Temporary Securities. Until Definitive Securities are ready for delivery, the Company may prepare and, upon written order of the Company, the Trustee shall authenticate temporary Securities. Temporary Securities shall be substantially in the form of Definitive Securities but may have variations that the Company considers appropriate for temporary Securities. Without unreasonable delay, the Company shall prepare and the Trustee shall authenticate and deliver Definitive Securities in exchange for a like principal amount of temporary Securities surrendered to it. Until so exchanged, temporary Securities shall in all respects be entitled to the same benefits under this Indenture as Definitive Securities. SECTION 2.11. Cancellation. The Company or any Subsidiary Guarantor at any time may deliver Securities to the Trustee for cancellation. The Registrar and Paying Agent shall forward to the Trustee any Securities surrendered to them for transfer, exchange or payment. The Trustee shall cancel all Securities surrendered for registration, transfer, exchange, payment or cancellation and shall destroy canceled Securities unless the Company directs their return to the Company. Except as provided in Section 2.07, the Company may not issue new Securities to replace Securities that it has paid or delivered to the Trustee for cancellation. Securities that are redeemed by the Company, that are repurchased by the Company pursuant to Section 4.11 or Section 4.16, or that are otherwise acquired by the Company, will be surrendered to the Trustee for cancellation. SECTION 2.12. Defaulted Interest. If the Company defaults in a payment of interest on the Securities, it shall pay, or cause the Paying Agent to pay, the defaulted interest in any lawful manner (plus interest on such defaulted interest to the extent lawful) (taken together, the "Defaulted Interest") to the persons who are Holders on a subsequent special record date, in each case at the rate provided in the Securities and in Section 4.01 hereof. At least 15 days before the special record date, the Company shall mail to each Holder a notice stating the special record date, the payment date and the amount of Defaulted Interest to be paid. In the event that the Company has elected to cause a Paying Agent to pay the Defaulted Interest, the Company shall so notify the Paying Agent at least 15 days before the special record date, which notice shall also set forth the special record date, the payment date and the aggregate amount of Defaulted Interest to be paid. At least five days before such payment date, the Company shall deposit with the Paying Agent money sufficient to pay all of the Defaulted Interest on the payment date therefor and instruct the Paying Agent in writing to pay to specified Holders on the payment date. On the payment date, the Paying Agent shall make the payments in accordance with the Company's written instructions from funds deposited with the Paying Agent for the purpose of making such Defaulted Interest payments. SECTION 2.13. Persons Deemed Owners. The Company, the Trustee, any Paying Agent and any authenticating agent may treat the Person in whose name any Security (including, without limitation, any Global Security) is registered as the owner of such Security for the purpose of receiving payments of principal of, premium, if any, or interest on such Security and for all other purposes. None of the Company, the Trustee, any Paying Agent or any authenticating agent shall be affected by any notice to the contrary. ARTICLE THREE REDEMPTION SECTION 3.01. Notice to Trustee. If the Company elects to redeem Securities pursuant to the optional redemption provisions of Paragraphs 6, 7 or 8 of the Securities, it shall furnish to the Trustee and the Registrar, at least 45 days but not more than 60 days before the redemption date (unless the Trustee consents to a shorter period in writing), an Officers' Certificate -22- 29 setting forth the redemption date, the principal amount of Securities to be redeemed and the redemption price, including the detail of the calculation of the Make-Whole Price, if applicable. SECTION 3.02. Selection of Securities to Be Redeemed. If less than all of the Securities are to be redeemed at any time, the Trustee shall select the Securities to be redeemed pro rata, by lot or, if the Securities are listed on any securities exchange, by any other method that the Trustee considers fair and appropriate and that complies with the requirements of such exchange; provided, however, that no Securities with a principal amount of $1,000 or less will be redeemed in part. The Trustee shall make the selection from outstanding Securities not previously called for redemption not less than 30 nor more than 45 days prior to the redemption date. Securities and portions of them it selects shall be in amounts of $1,000 or whole multiples of $1,000. Provisions of this Indenture that apply to Securities called for redemption also apply to portions of Securities called for redemption. The Trustee shall notify the Company promptly of the Securities or portions of Securities selected for redemption. SECTION 3.03. Notice of Redemption. (a) At least 30 days but not more than 60 days before a redemption date, the Company shall mail a notice of redemption by first-class mail to each Holder of Securities to be redeemed at such Holder's registered address. The notice shall identify the Securities to be redeemed and shall state: (1) the redemption date; (2) the redemption price; (3) the aggregate principal amount of Securities being redeemed; (4) the name and address of the Paying Agent; (5) that Securities called for redemption must be surrendered to the Paying Agent at the address specified in such notice to collect the redemption price; (6) that, unless the Company defaults in the payment of the redemption price or accrued interest, interest on Securities called for redemption ceases to accrue on and after the redemption date and the only remaining right of the Holders is to receive payment of the redemption prices in respect of the Securities upon surrender to the Paying Agent of the Securities; (7) if any Security is being redeemed in part, the portion of the principal amount of such Security to be redeemed and that, after the redemption date, upon surrender of such Security, a new Security or Securities in principal amount equal to the unredeemed portion will be issued in the name of the Holder thereof upon cancellation of the Security or Securities being redeemed; (8) the paragraph of the Securities pursuant to which the Securities called for redemption are being redeemed; and (9) the CUSIP number of the Securities. (b) At the Company's request, the Trustee shall give the notice of redemption required in Section 3.03(a) in the Company's name and at the Company's expense; provided, however, that the Company shall deliver to the Trustee, at least 45 days prior to the redemption date (unless the Trustee consents to a shorter notice period in writing), an Officers' Certificate requesting that the Trustee give such notice and setting forth the information to be stated in such notice as provided in Section 3.03(a). -23- 30 SECTION 3.04. Effect of Notice of Redemption. Once notice of redemption is mailed in accordance with Section 3.03, Securities called for redemption become due and payable on the redemption date at the redemption price. Upon surrender to the Paying Agent, such Securities shall be paid at the redemption price, plus accrued and unpaid interest to the redemption date. SECTION 3.05. Deposit of Redemption Price. Prior to the redemption date, the Company shall deposit with the Paying Agent funds available on the redemption date sufficient to pay the redemption price of, and accrued and unpaid interest on, the Securities to be redeemed on that date. The Paying Agent shall promptly return to the Company any money so deposited which is not required for that purpose upon the written request of the Company, except with respect to monies owed as obligations to the Trustee pursuant to Article Seven. If any Security called for redemption shall not be so paid upon redemption because of the failure of the Company to comply with the preceding paragraph, interest will continue to be payable on the unpaid principal and premium, if any, including from the redemption date until such principal and premium, if any, is paid, and, to the extent lawful, on any interest not paid on such unpaid principal, in each case at the rate provided in the Securities and in Section 4.01 hereof. SECTION 3.06. Securities Redeemed in Part. Upon surrender of a Security that is to be redeemed in part, the Company shall issue and the Trustee shall authenticate for the Holder, at the expense of the Company, a new Security equal in aggregate amount to the unredeemed portion of the Security surrendered. SECTION 3.07. Optional Redemption. Except as set forth in Sections 3.08 and 3.09 hereof, the Company shall not have the option to redeem the Securities prior to May 1, 2002. The Securities may be redeemed at the option of the Company, in whole or from time to time in part, at any time on or after May 1, 2002, at the redemption prices set forth below (expressed as a percentage of the principal amount of the Securities to be redeemed), together with accrued and unpaid interest on the Securities so redeemed to the redemption date, if redeemed during the 12-month period commencing on May 1 of the years indicated below: Redemption Year Price ---- ---------- 2002 . . . . . . . . . . . . . . . . . . . . 104.813% 2003 . . . . . . . . . . . . . . . . . . . . 102.406% 2004 and thereafter . . . . . . . . . . . . 100.000% Any redemption pursuant to this Section 3.07 shall be made, to the extent applicable, pursuant to the provisions of Sections 3.01 through 3.06 hereof.

At any time prior to May 1, 2002, the Company may, at its option, redeem all or any portion of the Securities at the "Make-Whole Price" (hereinafter defined) plus accrued and unpaid interest on the Securities so redeemed to the date of redemption. For purposes hereof, the term "Make-Whole Price" means the greater of (i) the sum of (A) the outstanding principal amount of the Securities to be redeemed plus (B) the Make-Whole Amount and (ii) the redemption price (expressed as a percentage of the principal amount) of the Securities on May 1, 2002 set forth in Section 3.07. Any redemption pursuant to this Section 3.09 shall be made, to the extent applicable, pursuant to the provisions of Sections 3.01 through 3.06 hereof. ARTICLE FOUR COVENANTS SECTION 4.01. Payment of Securities. The Company shall pay the principal of, premium, if any, and interest on, the Securities on the dates and in the manner provided in the Securities and this Indenture. Principal, premium and interest shall be considered paid on the date due if the Trustee or Paying Agent holds on that date money deposited by the Company designated for and sufficient to pay all principal, premium and interest then due. All references to interest in this Indenture shall for all purposes be deemed to include any additional interest payable as liquidated damages pursuant to the Registration Rights Agreement. The Company shall pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue principal, and premium, if any, at the rate borne by the Securities to the extent lawful; and it shall pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue installments of interest (without regard to any applicable grace period) at the same rate to the extent lawful.

SECTION 4.04. Maintenance of Office or Agency. The Company will maintain in the Borough of Manhattan, The City of New York, an office or agency where Securities may be surrendered for registration of transfer or exchange or for presentation for payment and where notices and demands to or upon the Company in respect of the Securities and this Indenture may be served. The Company will give prompt written notice to the Trustee of the location, and any change in the location, of such office or agency. If at any time the Company shall fail to maintain any such required office or agency or shall fail to furnish the Trustee with the address thereof, such presentations, surrenders, notices and demands may be made or served at the address of the Trustee set forth in Section 11.02. If at any time the Company shall fail to maintain any required office or agency or shall fail to furnish the Trustee with the address thereof, such surrenders, presentations, notices and demands may be made or served at the corporate trust office of the Trustee. Subject to Section 2.03, the Company may also from time to time designate one or more other offices or agencies where the Securities may be presented or surrendered for any or all such purposes and may from time to time rescind such designations; provided, that no such designation or rescission shall in any manner relieve the Company of its obligation to maintain an office or agency in the Borough of Manhattan, The City of New York, for such purposes. The Company will give prompt written notice to the Trustee of any such designation or rescission and of any change in the location of any such other office or agency. -26- 33 SECTION 4.05. Corporate Existence. The Company will do or cause to be done all things necessary to preserve and keep in full force and effect its corporate existence and the corporate, partnership or other existence of each Subsidiary and all rights (charter and statutory) and franchises of the Company and the Subsidiaries; provided, that the Company shall not be required to preserve the corporate existence of any Subsidiary, or any such right or franchise, if the Board of Directors of the Company shall determine that the preservation thereof is no longer desirable in the conduct of the business of the Company and that the loss thereof is not disadvantageous in any material respect to the Holders. SECTION 4.06. Waiver of Stay, Extension or Usury Laws. The Company and each Subsidiary Guarantor covenants (to the extent that each may lawfully do so) that it will not at any time insist upon, plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay, extension, or usury law or other law, which would prohibit or forgive the Company or any Subsidiary Guarantor from paying all or any portion of the principal of, premium, if any, or interest on the Securities as contemplated herein, wherever enacted, now or at any time hereafter in force, or which may affect the covenants or the performance of this Indenture; and (to the extent that it may lawfully do so) each of the Company and the Subsidiary Guarantors hereby expressly waives all benefit or advantage of any such law, and covenants that it will not hinder, delay or impede the execution of any power herein granted to the Trustee, but will suffer and permit the execution of every such power as though no such law had been enacted. SECTION 4.07. Payment of Taxes and Other Claims. The Company shall pay or discharge or cause to be paid or discharged, before the same shall become delinquent, (a) all taxes, assessments and governmental charges levied or imposed upon the Company or any Subsidiary or upon the income, profits or property of the Company or any Subsidiary and (b) all lawful claims for labor, materials and supplies which, if unpaid, might by law become a Lien upon the property of the Company or any Subsidiary; provided, however, that the Company shall not be required to pay or discharge or cause to be paid or discharged any such tax, assessment, charge or claim whose amount, applicability or validity is being contested in good faith by appropriate proceedings. SECTION 4.08. Maintenance of Properties and Insurance.

(b) The Company shall provide or cause to be provided, for itself and each of its Subsidiaries, insurance (including appropriate self-insurance) against loss or damage of the kinds that, in the reasonable, good faith opinion of the Company, are adequate and appropriate for the conduct of the business of the Company and such Subsidiaries in a prudent manner, with reputable insurers or with the government of the United States or an agency or instrumentality thereof, in such amounts, with such deductibles, and by such methods as shall be customary, in the reasonable, good faith opinion of the Company, for corporations similarly situated in the industry. SECTION 4.09. Limitation on Incurrence of Additional Indebtedness. (a) The Company will not, and will not permit any of its Restricted Subsidiaries, directly or indirectly, to issue, incur, assume, guarantee, become liable, contingently or otherwise, with respect to or otherwise become responsible for the payment of (collectively, "incur") any Indebtedness; provided, however, that if no Default -27- 34 or Event of Default shall have occurred and be continuing at the time or as a consequence of the incurrence of such Indebtedness, the Company or its Restricted Subsidiaries may incur Indebtedness if, on a pro forma basis, after giving effect to such incurrence and the application of the proceeds therefrom, either of the following tests shall have been satisfied: (i) the Adjusted Consolidated EBITDA Coverage Ratio would have been at least 2.25 to 1.0; or (ii) Adjusted Consolidated Net Tangible Assets would have been equal to or greater than 200% of Indebtedness of the Company and its Restricted Subsidiaries.

(c) Any Indebtedness of a Person existing at the time such Person becomes a Restricted Subsidiary (whether by merger, consolidation, acquisition or otherwise) shall be deemed to be incurred by such Restricted Subsidiary at the time it becomes a Restricted Subsidiary. SECTION 4.10. Limitation on Restricted Payments. (a) The Company will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, make any Restricted Payment, unless: (i) no Default or Event of Default shall have occurred and be continuing at the time of or immediately after giving effect to such Restricted Payment; (ii) at the time of and immediately after giving effect to such Restricted Payment, the Company would be able to incur at least $1.00 of additional Indebtedness (other than Permitted Indebtedness) pursuant to Section 4.09(a); and (iii) immediately after giving effect to such Restricted Payment, the aggregate of all Restricted Payments declared or made after the Issue Date does not exceed the sum of (A) 50% of the Consolidated Net Income of the Company and its Restricted Subsidiaries (or in the event such Consolidated Net Income shall be a deficit, minus 100% of such deficit) during the period (treated as one accounting period) subsequent to March 31, 1998 and ending on the last day of the fiscal quarter immediately preceding the date of such Restricted Payment; (B) the aggregate Net Cash Proceeds, and the fair market value of property other than cash (as determined in good faith by the Company's Board of Directors, including a majority of the Company's Disinterested Directors, and evidenced by a resolution of such Board), received by the Company during such period from any Person other than a Subsidiary of the Company as a result of the issuance or sale of Capital Stock of the Company (other than any Disqualified Stock and other than Preferred Shares issued in the Preferred Stock Offering), other than in connection with the conversion of Indebtedness or Disqualified Stock; (C) the aggregate Net Cash Proceeds, and the fair market value of property other than cash (as determined in good faith by the Company's Board of Directors and evidenced by a resolution of such Board), received by the Company during such period from any Person other than a Subsidiary of the Company as a result of the issuance or sale of any Indebtedness or Disqualified Stock to the extent that at the time the determination is made such Indebtedness or Disqualified Stock, as the case may be, has been converted into or exchanged for Capital Stock of the Company (other than Disqualified Stock); (D)(i) in case any Unrestricted Subsidiary has been redesignated a Restricted Subsidiary, an amount equal to the lesser of (x) the book value (determined in accordance with GAAP) at the date of such redesignation of the aggregate Investments made by the Company and its Restricted Subsidiaries in such Unrestricted Subsidiary and (y) the fair market value of such Investments in such Unrestricted Subsidiary at the time of such redesignation, as determined in good faith by the Company's Board of Directors, including a majority of the Company's Disinterested Directors, whose determination shall be conclusive and evidenced by a resolution of such Board; or (ii) in case any Restricted Subsidiary has been redesignated an Unrestricted Subsidiary, minus the greater of (x) the book value (determined in accordance with GAAP) at the date of redesignation of the aggregate Investments made by the -28- 35 Company and its Restricted Subsidiaries in such Restricted Subsidiary and (y) the fair market value of such Investments in such Restricted Subsidiary at the time of such redesignation, as determined in good faith by the Company's Board of Directors, including a majority of the Company's Disinterested Directors, whose determination shall be conclusive and evidenced by a resolution of such Board; and (E) $25,000,000. (b) Notwithstanding the foregoing, the above limitations will not prevent (i) the payment of any dividend within 60 days after the date of declaration thereof, if at such date of declaration such payment complied with the provisions hereof; (ii) the purchase, redemption, acquisition or retirement of any shares of Capital Stock of the Company in exchange for, or out of the net proceeds of the substantially concurrent sale (other than to a Restricted Subsidiary of the Company) of, other shares of Capital Stock (other than Disqualified Stock) of the Company; and (iii) any dividend or other distribution payable from a Subsidiary to the Company or any Restricted Subsidiary. SECTION 4.11. Limitation on Sale of Assets. (a) The Company will not, and will not permit any Restricted Subsidiary to, make any Asset Sale unless: (i) the Company (or its Restricted Subsidiaries, as the case may be) receives consideration at the time of such sale or other disposition at least equal to the fair market value thereof (as determined in good faith by the Company's Board of Directors and evidenced by a resolution of such Board, including a majority of the Company's Disinterested Directors, in the case of any Asset Sales or series of related Asset Sales having a fair market value of $20,000,000 or greater); (ii) at least 75% of the proceeds from such Asset Sale consist of cash, cash equivalents or property, equipment, leasehold interests or other assets used in the Oil and Gas Business; and (iii) the Net Available Proceeds received by the Company (or its Restricted Subsidiaries, as the case may be) from such Asset Sale are applied in accordance with paragraphs (b) or (c) hereof. (b) The Company may apply such Net Available Proceeds within 365 days after receipt of Net Available Proceeds from any Asset Sale, to: (i) the repayment of Indebtedness of the Company under a Bank Credit Facility or other Senior Indebtedness, including any mandatory redemption or repurchase or optional redemption of the Existing Notes or the Securities; (ii) make an Investment in assets used in the Oil and Gas Business; or (iii) develop by drilling the Company's oil and gas reserves. (c) If, upon completion of the 365-day period referred to above, any portion of the Net Available Proceeds of any Asset Sale shall not have been applied by the Company as described in clauses (i), (ii) or (iii) of the immediately preceding paragraph and such remaining Net Available Proceeds, together with any remaining net cash proceeds from any prior Asset Sale (such aggregate constituting "Excess Proceeds"), exceed $15,000,000, then the Company will be obligated to make an offer (the "Net Proceeds Offer") to purchase the Securities and any other Senior Indebtedness in respect of which such an offer to purchase is required to be made concurrently with the Net Proceeds Offer having an aggregate principal amount equal to the Excess Proceeds (such purchase to be made on a pro rata basis if the amount available for such repurchase is less than the principal amount of the Senior Notes and other Senior Indebtedness tendered in such Net Proceeds Offer) at a purchase price of 100% of the principal amount thereof plus accrued and unpaid interest on the Securities and other Senior Indebtedness so repurchased to the date of repurchase. Upon the completion of the Net Proceeds Offer, the amount of Excess Proceeds will be reset to zero. (d) The Company shall commence a Net Proceeds Offer by preparing and mailing a notice to the Trustee, the Paying Agent and each Holder as of such record date as the Company shall establish (upon written notice to the Trustee). Notice of a Net Proceeds Offer to purchase the Securities will be made on behalf of the Company not less than 25 Business Days nor more than 60 Business Days before the payment date of the Net Proceeds Offer (the "Net Proceeds Payment Date"), and shall set forth the Net Proceeds Offer Amount and the Net Proceeds Payment Date and refer to and summarize the material points contained in Sections 4.11(d) and (e) hereof. Securities tendered to the -29- 36 Company pursuant to a Net Proceeds Offer will cease to accrue interest after the Net Proceeds Payment Date. For purposes of this covenant, the term "Net Proceeds Offer Amount" means the principal of outstanding Securities in an aggregate principal amount equal to any remaining Net Available Proceeds (rounded to the next lowest $1,000). If the Net Proceeds Payment Date is on or after an interest payment record date and on or before the related interest payment date, any accrued interest payable on such interest payment date will be paid to the Person in whose name a Security is registered at the close of business on such record date, and no additional interest will be payable to Holders who tender Securities pursuant to the Net Proceeds Offer. (e) On the Net Proceeds Payment Date, the Company will (i) accept for payment Securities and any other Senior Indebtedness in respect of which such an offer to purchase is required to be made concurrently with the Net Proceeds Offer or portions thereof pursuant to the Net Proceeds Offer in an aggregate principal amount equal to the Net Proceeds Offer Amount or such lesser amount as has been tendered, (ii) deposit with the Paying Agent money sufficient to pay the purchase price of all Securities and such other Senior Indebtedness or portions thereof so tendered in an aggregate principal amount equal to the Net Proceeds Offer Amount or such lesser amount, including any accrued and unpaid interest thereon, and (iii) deliver or cause to be delivered to the Trustee, Securities so accepted together with an Officers' Certificate stating the Securities or portions thereof tendered to the Company. If the aggregate principal amount of Securities and such other Senior Indebtedness tendered exceeds the Net Proceeds Offer Amount, the Trustee will select the Securities and other Senior Indebtedness to be purchased (in integral multiples of $1,000) on a pro rata basis based on the principal amount of Securities and other Senior Indebtedness so tendered and notify the Company, the Registrar and the Paying Agent. The Paying Agent, upon instruction of the Company, will promptly mail or deliver to Holders of Securities so accepted payment in an amount equal to the purchase price (representing those funds received pursuant to clause (ii) of this Section 4.11(e)), and the Company will execute and the Trustee will promptly authenticate and mail or make available for delivery to Holders a new Security equal in principal amount to any unpurchased portion of the Security surrendered. Any Securities not so accepted will be promptly mailed or delivered to the Holder thereof by the Company, or, if the Company so directs the Trustee, by the Trustee on behalf of the Company at the Company's expense. The Company will publicly announce the results of the Net Proceeds Offer on or as soon as practicable after the Net Proceeds Payment Date. For purposes of this Section 4.11, the Trustee will act as the Paying Agent. (f) The Company will comply with Section 14 of the Exchange Act and the provisions of Regulation 14E and any other tender offer rules under the Exchange Act and any other federal and state securities laws, rules and regulations which may then be applicable to any Net Proceeds Offer. (g) During the period between any Asset Sale and the application of the Net Available Proceeds therefrom in accordance with this covenant, all Net Available Proceeds shall be maintained in a segregated account and shall be invested in Permitted Financial Investments. (h) Notwithstanding the foregoing, the Company will not and will not permit any Restricted Subsidiary to, directly or indirectly, make any Asset Sale of any of the Capital Stock of a Restricted Subsidiary except pursuant to an Asset Sale of all of the Capital Stock of such Restricted Subsidiary. SECTION 4.12. Limitation on Liens Securing Indebtedness. The Company will not, and will not permit any of its Restricted Subsidiaries to, create, incur, assume or suffer to exist any Liens (other than Permitted Liens) upon any of their respective properties securing (i) any Indebtedness of the Company, unless the Securities are equally and ratably secured or (ii) any Indebtedness of any Restricted Subsidiary, unless the Guarantees are equally and ratably secured; provided, that if such Indebtedness is expressly subordinated to the Securities or the Guarantees, the Lien securing such Indebtedness will be subordinated and junior to any Lien securing the Securities or the Guarantees, with the same relative priority as such Subordinated Indebtedness of the Company or Subordinated Indebtedness of a Restricted Subsidiary will have with respect to the Securities or the Guarantees, as the case may be. -30- 37 SECTION 4.13. Limitation on Sale/Leaseback Transactions. The Company will not, and will not permit any of its Restricted Subsidiaries to, enter into any Sale/Leaseback Transaction with any Person (other than the Company or any Wholly Owned Restricted Subsidiary) unless (i) the Company or such Restricted Subsidiary, as the case may be, would be able to incur Indebtedness in a principal amount equal to the Attributable Indebtedness with respect to such Sale/Leaseback Transaction in accordance with Section 4.09 or (ii) the Company or such Restricted Subsidiary receives proceeds from such Sale/Leaseback Transaction at least equal to the fair market value thereof (as determined in good faith by the Company's Board of Directors, whose determination in good faith, evidenced by a resolution of such Board shall be conclusive) and such proceeds are applied in the same manner and to the same extent as Net Available Proceeds and Excess Proceeds from an Asset Sale. SECTION 4.14. Limitation on Payment Restrictions Affecting Subsidiaries. The Company will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, create or otherwise cause or suffer to exist or become effective any consensual encumbrance or consensual restriction on the ability of any Restricted Subsidiary of the Company to (i) pay dividends or make any other distributions on its Capital Stock or on any other interest or participation in the Company or a Restricted Subsidiary, (ii) pay any Indebtedness owed to the Company or a Restricted Subsidiary of the Company; (iii) make loans or advances to the Company or a Restricted Subsidiary of the Company; or (iv) transfer any of its properties or assets to the Company or a Restricted Subsidiary of the Company (each, a "Payment Restriction"), except for (a) encumbrances or restrictions under a Bank Credit Facility; provided, that any Payment Restrictions thereunder (other than, with respect to (iv) above, customary restrictions in security agreements or other loan documents thereunder securing or governing Indebtedness of a Restricted Subsidiary) may be imposed only upon the acceleration of the maturity of the Indebtedness thereunder; (b) consensual encumbrances or consensual restrictions binding upon any Person at the time such Person becomes a Restricted Subsidiary of the Company (unless the agreement creating such consensual encumbrances or consensual restrictions was entered into in connection with, or in contemplation of, such entity becoming a Restricted Subsidiary); (c) consensual encumbrances or consensual restrictions under any agreement that refinances or replaces any agreement described in clauses (a) and (b) above, provided that the terms and conditions of any such restrictions are in the aggregate no less favorable to the holders of the Securities than those under the agreement so refinanced or replaced; and (d) customary non-assignment provisions in leases, purchase money financings and any encumbrance or restriction due to applicable law. SECTION 4.15. Limitation on Transactions with Affiliates. The Company will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, enter into any transaction or series of transactions (including, without limitation, the sale, purchase or lease of any assets or properties or the rendering of any services) with any Affiliate or beneficial owner (as defined in Rules 13d-3 and 13d-5 under the Exchange Act) of 10% or more of the Company's common stock (other than with a Wholly Owned Restricted Subsidiary of the Company) (an "Affiliate Transaction"), on terms that are less favorable to the Company or such Restricted Subsidiary, as the case may be, than would be available in a comparable transaction with an unrelated Person. In addition, the Company will not, and will not permit any Restricted Subsidiary of the Company to, enter into an Affiliate Transaction, or any series of related Affiliate Transactions having a value of (a) more than $5,000,000 unless a majority of the Board of Directors of the Company (including a majority of the Company's Disinterested Directors) determines in good faith, as evidenced by a resolution of such Board, that such Affiliate Transaction or series of related Affiliate Transactions is fair to the Company; or (b) more than $25,000,000, unless the Company receives a written opinion from a nationally recognized investment banking firm with total assets in excess of $1.0 billion that such transaction or series of transactions is fair to the Company from a financial point of view. -31- 38 SECTION 4.16. Change of Control. (a) Following the occurrence of any Change of Control, the Company shall offer (a "Change of Control Offer") to purchase all outstanding Securities at a purchase price equal to 101% of the aggregate outstanding principal amount of the Securities, plus accrued and unpaid interest on the Securities so purchased to the date of purchase. The Change of Control Offer shall be deemed to have commenced upon mailing of the notice described in the next succeeding paragraph and shall terminate 20 Business Days after its commencement, unless a longer offering period is required by law. Promptly after the termination of the Change of Control Offer (the "Change of Control Payment Date"), the Company shall purchase and mail or deliver payment for all Securities tendered in response to the Change of Control Offer. If the Change of Control Payment Date is on or after an interest payment record date and on or before the related interest payment date, any accrued interest payable on such interest payment date will be paid to the Person in whose name a Security is registered at the close of business on such record date, and no additional interest will be payable to Holders who tender Securities pursuant to the Change of Control Offer. (b) Within 15 days after any Change of Control, the Company (with notice to the Trustee and the Paying Agent), or the Trustee at the Company's request and expense, will mail or cause to be mailed to all Holders on the date of the Change of Control a notice prepared by the Company (the "Change of Control Notice") of the occurrence of such Change of Control and of the Holders' rights arising as a result thereof. The Change of Control Notice will contain all instructions and materials necessary to enable Holders to tender their Securities to the Company. The Change of Control Notice, which shall govern the terms of the Change of Control Offer, shall state: (1) that the Change of Control Offer is being made pursuant to this Section 4.16; (2) the purchase price and the Change of Control Payment Date; (3) that any Security not tendered will continue to accrue interest at the stated rate; (4) that any Security accepted for payment pursuant to the Change of Control Offer shall cease to accrue interest on the Change of Control Payment Date; (5) that Holders electing to have a Security purchased pursuant to any Change of Control Offer will be required to surrender the Security, with the form entitled "Option of Holder to Elect Purchase" on the reverse of the Security completed, to the Company, a depositary, if appointed by the Company, or a Paying Agent at the address specified in the notice prior to termination of the Change of Control Offer; (6) that Holders will be entitled to withdraw their election if the Company, depositary or Paying Agent, as the case may be, receives, not later than the expiration of the Change of Control Offer, or such longer period as may be required by law, a telegram, telex, facsimile transmission or letter setting forth the name of the Holder, the principal amount of the Security the Holder delivered for purchase and a statement that such Holder is withdrawing its election to have the Security purchased; and (7) that Holders whose Securities are purchased only in part will be issued Securities equal in principal amount to the unpurchased portion of the Securities surrendered. (c) On the Change of Control Payment Date, the Company shall, to the extent permitted by applicable law, (i) accept for payment Securities or portions thereof tendered pursuant to the Change of Control Notice, (ii) if the Company appoints a depositary or Paying Agent, deposit with such depositary or Paying Agent money sufficient to pay the purchase price of all Securities or portions thereof so tendered and (iii) deliver to the Trustee Securities so accepted together with an Officers' Certificate stating the Securities or portions thereof tendered to the Company. The depositary, the Company or the Paying Agent, as the case may be, shall promptly mail to the Holders of Securities so accepted payment in an amount equal to the purchase price (representing those funds received pursuant to clause (ii) of this Section 4.16(c)), and the Trustee shall promptly authenticate and mail to each such Holder a new Security equal in principal amount to any unpurchased portion of the Security surrendered; provided that each such new Security will be in a principal amount of $1,000 or an integral multiple thereof. The Company will publicly announce the results of the Change of Control Offer on or as soon as practicable after the Change of Control Payment Date. For purposes of this Section 4.16, the Trustee shall act as the Paying Agent. (d) The Company will comply with Section 14 of the Exchange Act and the provisions of Regulation 14E and any other tender offer rules under the Exchange Act and any other federal and state securities laws, rules and regulations which may then be applicable to any offer by the Company to purchase the Securities at the option of the Holders upon a Change of Control. -32- 39 ARTICLE FIVE SUCCESSOR CORPORATION SECTION 5.01.

If an Event of Default (other than an Event of Default specified in clauses (8) or (9)) under Section 6.01 occurs and is continuing, then and in every such case the Trustee or the Holders of not less than 25% of the principal amount of the outstanding Securities may declare the unpaid principal of and premium, if any, or the Change of Control purchase price if the Event of Default includes failure to pay the Change of Control purchase price, and accrued and unpaid interest on, all the Securities then outstanding to be due and payable, by a notice in writing to the Company (and to the Trustee, if given by Holders), and upon any such declaration such principal, premium, if any, and accrued and unpaid interest shall become immediately due and payable, notwithstanding anything contained in this Indenture or the Securities to the contrary. If an Event of Default specified in clauses 8 or 9 above occurs, all unpaid principal of, and premium, if any, and accrued and unpaid interest on, the Securities then outstanding will become due and payable, without any declaration or other act on the part of the Trustee or any Holder. The Holders of a majority of the principal amount of the outstanding Securities, by written notice to the Company, the Subsidiary Guarantors and the Trustee, may rescind and annul a declaration of acceleration and its consequences if (1) the Company or any Subsidiary Guarantor has paid or deposited with such Trustee a sum sufficient to pay (A) all overdue installments of interest on all the Securities, (B) the principal of, and premium, if any, on any Securities that have become due otherwise than by such declaration of acceleration and interest thereon at the rate or rates prescribed therefor in the Securities, (C) to the extent that payment of such interest is lawful, interest on the defaulted interest at the rate or rates prescribed therefor in the Securities, and (D) all money paid or advanced by the Trustee thereunder and the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel; (2) all Events of Default, other than the non-payment of the principal of any Securities that have become due solely by such declaration of acceleration, have been cured or waived as provided in this Indenture; and (3) the rescission would not conflict with any judgment or decree of a court of competent jurisdiction. No such rescission will affect any subsequent Event of Default or impair any right consequent thereon. SECTION 6.03. Other Remedies. If an Event of Default occurs and is continuing, the Trustee may, but is not obligated to, pursue, in its own name and as trustee of an express trust, any available remedy by proceeding at law or in equity to collect the payment of principal or interest on the Securities or to enforce the performance of any provision of the Securities or this Indenture. If an Event of Default specified under clauses (8) or (9) of Section 6.01 occurs with respect to the Company at a time when the Company is the Paying Agent, the Trustee shall automatically assume the duties of Paying Agent. The Trustee may maintain a proceeding even if it does not possess any of the Securities 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 -35- 42 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 6.04. Waiver of Past Defaults. Subject to Sections 6.07 and 9.02, the Holders of at least a majority of the principal amount of the outstanding Securities by notice to the Trustee may waive an existing Default or Event of Default and its consequences, except a Default or Event of Default in payment of principal or interest on the Securities, including any optional redemption payments or Change of Control or Net Proceeds Offer payments. SECTION 6.05. Control by Majority. The Holders of a majority in principal amount of the Securities will have the right to direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or exercising any trust or power conferred on such Trustee, provided that (1) such direction is not in conflict with any rule of law or with this Indenture and (2) the Trustee may take any other action deemed proper by such Trustee that is not inconsistent with such direction. SECTION 6.06. Limitation on Remedies. No Holder of any of the Securities will have any right to institute any proceeding, judicial or otherwise, or for the appointment of a receiver or trustee or pursue any remedy under this Indenture, unless: (1) such Holder has previously given notice to the Trustee of a continuing Event of Default, (2) the Holders of not less than 25% of the principal amount of the outstanding Securities have made written request to such Trustee to institute proceedings in respect of such Event of Default in its own name as Trustee under this Indenture, (3) such Holder or Holders have offered to such Trustee reasonable indemnity against the costs, expenses and liabilities to be incurred in compliance with such request, (4) such Trustee for 60 days after its receipt of such notice, request and offer of indemnity has failed to institute any proceeding, and (5) no direction inconsistent with such written request has been given to such Trustee during such 60-day period by the Holders of a majority of the principal amount of the outstanding Securities. A Holder may not use this Indenture to prejudice the rights of another Holder or to obtain a preference or priority over other Holders. SECTION 6.07. Rights of Holders to Receive Payment. Notwithstanding any other provision of this Indenture, the Holder of any Securities will have the right, which is absolute and unconditional, to receive payment of the principal of and interest on such Securities on the stated maturity therefor and to institute suit for the enforcement of any such payment, and such right may not be impaired without the consent of such Holder. -36- 43 SECTION 6.08. Collection Suit by Trustee. If an Event of Default in payment of principal, premium, if any, or interest specified in Section 6.01(1), (2) or (3) occurs and is continuing, the Trustee may recover judgment in its own name and as trustee of an express trust against the Company or any Subsidiary Guarantor for the whole amount of principal, premium, if any, and interest remaining unpaid with respect to the Securities, and interest on overdue principal and premium, if any, and, to the extent lawful, interest on overdue interest, and such further amounts as shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation and expenses of the Trustee, its agents and counsel. SECTION 6.09. Trustee May File Proofs of Claim. (a) 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 and the Holders allowed in any judicial proceedings relative to the Company, the Subsidiary Guarantors, their creditors or their property and may collect and receive any money or securities or other property payable or deliverable on any such claims and to distribute the same. (b) Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the Securities or the rights of any Holder thereof, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding. SECTION 6.10. Priorities. If the Trustee collects any money pursuant to this Article Six, it shall pay out the money in the following order: First: to the Trustee for amounts due under Section 7.07; Second: to Holders for amounts due and unpaid on the Securities for principal and interest, ratably, without preference or priority of any kind, according to the amounts due and payable on the Securities for principal and interest, respectively; and Third: to the Company. The Trustee may fix a record date and payment date for any payment to Holders pursuant to this Section 6.10. SECTION 6.11. 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 6.11 does not apply to a suit by the Trustee, a suit by a Holder pursuant to Section 6.07, or a suit by Holders of more than 10% in principal amount of the then outstanding Securities. -37- 44 ARTICLE SEVEN TRUSTEE SECTION 7.01. Duties of Trustee. (a) If an Event of Default has occurred and is continuing, the Trustee shall exercise such rights and powers vested in it by this Indenture and use the same degree of care and skill in such exercise as a prudent person would exercise or use under the circumstances in the conduct of such person's own affairs. (b) Except during the continuance of an Event of Default: (1) The Trustee need perform only those duties that are specifically set forth (or incorporated by reference) in this Indenture and no others. (2) In the absence of bad faith on its part, the Trustee may conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon certificates or opinions furnished to the Trustee and conforming to the requirements of this Indenture. However, the Trustee shall examine such certificates and opinions to determine whether or not they conform to the requirements of this Indenture. (c) The Trustee may not be relieved from liability for its own negligent action, its own negligent failure to act, or its own willful misconduct, except that: (1) This paragraph (c) does not limit the effect of paragraph (b) of this Section. (2) The Trustee shall not be liable for any error of judgment made in good faith by an officer of the Trustee, unless it is proved that the Trustee was negligent in ascertaining the pertinent facts. (3) The Trustee shall not be liable with respect to action it takes or omits to take in good faith in accordance with a direction received by it pursuant to Section 6.05, and the Trustee shall be entitled from time to time to request such a direction. (d) Every provision of this Indenture that in any way relates to the Trustee is subject to paragraphs (a), (b) and (c) of this Section. (e) The Trustee shall be under no obligation and may refuse to perform any duty or exercise any right or power unless it receives indemnity satisfactory to it against any loss, liability or expense. 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. (f) The Trustee shall not be liable for interest on any money received by it except as the Trustee may agree in writing with the Company. Money held in trust by the Trustee need not be segregated from other funds except to the extent required by law. SECTION 7.02. Rights of Trustee. Subject to Section 7.01: (a) The Trustee may rely on and shall be protected in acting or refraining from acting upon any document believed by it to be genuine and to have been signed or presented by the proper person. The Trustee shall not be bound to make any investigation into the facts or matters stated in any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture or other paper or document, but the Trustee, in its discretion, may make such further inquiry or investigation into such facts or matters as it may see fit, and, if the Trustee shall determine to make such further inquiry or investigation, it shall be entitled to examine the books, records and premises of the Company, personally or by agent or attorney, to the extent reasonably required by such inquiry or investigation. -38- 45 (b) Before the Trustee acts or refrains from acting, it may require an Officers' Certificate 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 such certificate or opinion. (c) The Trustee may act through agents and shall not be responsible for the misconduct or negligence of any agent appointed with due care. (d) The Trustee shall not be liable for any action it takes or omits to take in good faith which it believes to be authorized or within its rights or powers. SECTION 7.03. Individual Rights of Trustee. The Trustee in its individual or any other capacity may become the owner or pledgee of Securities and may otherwise deal with the Company or its Subsidiaries or Affiliates with the same rights it would have if it were not Trustee. Any Agent may do the same with like rights. However, the Trustee must comply with Sections 7.10 and 7.11. SECTION 7.04. Trustee's Disclaimer. The Trustee makes no representation as to the validity or adequacy of this Indenture or the Securities, it shall not be accountable for the Company's use of the proceeds from the Securities or any prospectus, offering or solicitation documents, and it shall not be responsible for any statement in the Securities other than its certificate of authentication. SECTION 7.05. Notice of Defaults. If a Default occurs and is continuing and if it is known to the Trustee, the Trustee shall mail to each Holder pursuant to Section 11.02 a notice of the Default within 90 days after it occurs. Except in the case of a Default in any payment on any Security, the Trustee may withhold the notice if and so long as the board of directors, executive committee or a trust committee of officers in good faith determines that withholding the notice is in the interests of Holders. SECTION 7.06. Reports by Trustee to Holders. Within 60 days after each April 1, beginning with the April 1 following the date of this Indenture, the Trustee shall mail to each Holder a brief report dated as of such April 1 that complies with TIA Section 313(a), but only if such report is required in any year under TIA Section 313(a). The Trustee also shall comply with TIA Sections 313(b) and 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 on which the Securities are listed. The Company shall notify the Trustee in writing when the Securities become listed on any national securities exchange or of any delisting thereof. SECTION 7.07. Compensation and Indemnity. The Company and the Subsidiary Guarantors jointly and severally agree to pay the Trustee from time to time reasonable compensation for its services (which compensation shall not be limited by any provision of law in regard to the compensation of a trustee of an express trust). The Company and the Subsidiary Guarantors jointly and severally agree to reimburse the Trustee upon request for all reasonable out-of-pocket expenses, disbursements and advances incurred by it. Such expenses shall include when applicable the reasonable compensation and expenses of the Trustee's agents and counsel. The Trustee shall not be under any obligation to institute any suit, or take any remedial action under this Indenture, or to enter any appearance or in any way defend any suit in which it may be a defendant, or to take any steps in the execution of the trusts created hereby or thereby or in the enforcement of any rights and powers under this Indenture, until it shall be indemnified to its satisfaction against any and all reasonable expenses, disbursements and -39- 46 advances incurred or made by the Trustee in accordance with any provisions of this Indenture, including compensation for services, costs, expenses, outlays, counsel fees and other disbursements, and against all liability not due to its negligence or willful misconduct. The Company and the Subsidiary Guarantors jointly and severally agree to indemnify the Trustee against any loss, liability or expenses incurred by it arising out of or in connection with the acceptance and administration of the trust and its duties hereunder as Trustee, Registrar and/or Paying Agent, including the costs and expenses of enforcing this Indenture against the Company (including with respect to this Section 7.07) and of defending itself against any claim or liability in connection with the exercise or performance of any of its powers or duties hereunder. The Trustee shall notify the Company and the Subsidiary Guarantors of any claim for which it may seek indemnity; however, unless the position of the Company is prejudiced by such failure, the failure of the Trustee to promptly notify the Company shall not limit its right to indemnification. The Company shall defend each such claim and the Trustee shall cooperate in the defense. The Trustee may retain separate counsel and the Company shall reimburse the Trustee for the reasonable fees and expenses of such counsel. The Company need not pay for any settlement made without its consent. Neither the Company nor the Subsidiary Guarantors shall be obligated to reimburse any expense or indemnify against any loss or liability incurred by the Trustee through the Trustee's negligence or willful misconduct. To secure the payment obligations of the Company and the Subsidiary Guarantors in this Section, the Trustee shall have a claim prior to that of the Holders of the Securities on all money or property held or collected by the Trustee, except that held in trust to pay principal of and interest on particular Securities. The Trustee's right to receive payment of any amounts due under this Section 7.07 shall not be subordinate to any other liability or Indebtedness of the Company. When the Trustee incurs expenses or renders services after the occurrence of any Event of Default specified in Sections 6.01(8) or (9), the expenses and the compensation for the services are intended to constitute expenses of administration under any Bankruptcy Law. SECTION 7.08. Replacement of Trustee. The Trustee may resign by so notifying the Company and the Subsidiary Guarantors. The Holders of a majority in principal amount of the Securities may remove the Trustee by so notifying the Trustee, in writing. The Company may remove the Trustee if: (1) the Trustee fails to comply with Section 7.10; (2) the Trustee is adjudged a bankrupt or an insolvent; (3) a receiver or other public officer takes charge of the Trustee or its property; or (4) the Trustee becomes incapable of acting as Trustee hereunder. If the Trustee resigns or is removed or if a vacancy exists in the office of Trustee for any reason, the Company shall promptly appoint a successor Trustee. Within one year after the successor Trustee takes office, the Holders of a majority in principal amount of the Securities may appoint a successor Trustee to replace the successor Trustee appointed by the Company. A successor Trustee shall deliver a written acceptance of its appointment to the retiring Trustee and to the Company and the Subsidiary Guarantors. Immediately after that, the retiring Trustee shall transfer all property held by it as Trustee to the successor Trustee, subject to the lien provided for in Section 7.07, the resignation or removal of the retiring Trustee shall become effective, and the successor Trustee shall have all the rights, powers and duties of the Trustee under this Indenture. A successor Trustee shall mail notice of its succession to each Holder. If a successor Trustee does not take office within 30 days after the retiring Trustee resigns or is removed, the retiring Trustee, the Company or the Holders of a majority in principal amount of the Securities may petition any court of competent jurisdiction for the appointment of a successor Trustee. -40- 47 If the Trustee fails to comply with Section 7.10, any Holder may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee. Any successor Trustee shall comply with TIA Section 310(a)(5). SECTION 7.09. Successor Trustee by Merger, etc. If the Trustee consolidates, merges or converts into, or transfers all or substantially all of its corporate trust assets to, another corporation, the successor corporation without any further act shall be the successor Trustee; provided such corporation or association shall be otherwise eligible and qualified under this Article. SECTION 7.10. Eligibility; Disqualification. This Indenture shall always have a Trustee which satisfies the requirements of TIA Section 310(a)(1). The Trustee shall always have a combined capital and surplus of at least $50,000,000 as set forth in its most recent published annual report of condition. The Trustee shall also comply with TIA Section 310(b). SECTION 7.11. Preferential Collection of Claims Against Company. 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 therein. ARTICLE EIGHT DISCHARGE OF INDENTURE SECTION 8.01. Option to Effect Legal Defeasance or Covenant Defeasance. The Company may, at the option of its Board of Directors evidenced by a resolution set forth in an Officers' Certificate, at any time, with respect to the Securities, elect to exercise its rights pursuant to either Section 8.02 or 8.03 with respect to all outstanding Securities upon compliance with the conditions set forth below in this Article Eight. SECTION 8.02. Legal Defeasance and Discharge. Upon the Company's exercise under Section 8.01 of the option applicable to this Section 8.02, the Company shall be deemed to have been discharged from its obligations with respect to all outstanding Securities on the date all conditions set forth below are satisfied (hereinafter, "Legal Defeasance"). For this purpose, such Legal Defeasance means that the Company shall be deemed to have paid and discharged the entire Indebtedness represented by the outstanding Securities, which shall thereafter be deemed to be "outstanding" only for the purposes of Section 8.05 and the other Sections of this Indenture referred to in (a) and (b) below, and to have satisfied all its other obligations under such Securities and this Indenture (and the Trustee, on demand of and at the expense of the Company, shall execute proper instruments acknowledging the same), except for the following which shall survive until otherwise terminated or discharged hereunder: (a) the rights of Holders of outstanding Securities to receive solely from the trust fund described in Section 8.04, and as more fully set forth in such Section, payments in respect of the principal of, premium, if any, and interest on such Securities when such payments are due, (b) the Company's obligations with respect to such Securities under Sections 2.03, 2.04, 2.06, 2.07, 2.10 and 4.04, (c) the rights, powers, trusts, duties and immunities of the Trustee hereunder and the Company's obligations in connection therewith (including, but not limited to, Section 7.07) and (d) this Article Eight. Subject to compliance with this Article Eight, the Company may exercise its option under this Section 8.02 notwithstanding the prior exercise of its option under Section 8.03 with respect to the Securities. -41- 48 SECTION 8.03. Covenant Defeasance. Upon the Company's exercise under Section 8.01 of the option applicable to this Section 8.03, the Company shall be released from its obligations under the covenants contained in the second sentence of Section 4.02, Sections 4.03, 4.07, 4.08, 4.09, 4.10, 4.11, 4.12, 4.13, 4.14, 4.15, and 4.16 and Article Five with respect to the outstanding Securities on and after the date the conditions set forth below are satisfied (hereinafter, "Covenant Defeasance"), and the Securities shall thereafter be deemed not "outstanding" for the purposes of any direction, waiver, consent or declaration or act of Holders (and the consequences of any thereof) in connection with such covenants, but shall continue to be deemed "outstanding" for all other purposes hereunder (it being understood that such Securities shall not be deemed outstanding for accounting purposes). For this purpose, such Covenant Defeasance means that, with respect to the outstanding Securities, the Company 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 shall not constitute a Default or an Event of Default under Section 6.01(5), but, except as specified above, the remainder of this Indenture and such Securities shall be unaffected thereby. In addition, upon the Company's exercise under Section 8.01 of the option applicable to this Section 8.03, Sections 6.01(4) through 6.01(9) shall not constitute Events of Default. SECTION 8.04. Conditions to Legal or Covenant Defeasance.

(b) In the case of an election under Section 8.02, the Company shall have delivered to the Trustee an Opinion of Counsel confirming that (i) the Company has received from, or there has been published by, the Internal Revenue Service a ruling or (ii) since the date hereof, there has been a change in the applicable federal income tax law, in either case to the effect that, and based thereon such opinion shall confirm that, the Holders of the outstanding Securities will not recognize income, gain or loss for federal income tax purposes as a result of such Legal Defeasance and will be subject to federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Legal Defeasance had not occurred; (c) In the case of an election under Section 8.03, the Company shall have delivered to the Trustee an Opinion of Counsel to the effect that the Holders of the outstanding Securities will not recognize income, gain or loss for federal income tax purposes as a result of such Covenant Defeasance and will be subject to federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Covenant Defeasance had not occurred; (d) No Default or Event of Default with respect to the Securities shall have occurred and be continuing on the date of such deposit or, insofar as Subsection 6.01(8) or 6.01(9) is concerned, at any time in the period -42- 49 ending on the 91st day after the date of such deposit (it being understood that this condition shall not be deemed satisfied until the expiration of such period); (e) Such Legal Defeasance or Covenant Defeasance shall not result in a breach or violation of, or constitute a default under, this Indenture or any other material agreement or instrument to which the Company is a party or by which the Company is bound; (f) In the case of any election under Section 8.02 or 8.03, the Company shall have delivered to the Trustee an Officers' Certificate stating that the deposit made by the Company pursuant to its election under Section 8.02 or 8.03 was not made by the Company with the intent of preferring the Holders over other creditors of the Company or with the intent of defeating, hindering, delaying or defrauding creditors of the Company or others; and (g) The Company shall have delivered to the Trustee an Officers' Certificate and an Opinion of Counsel, each stating that all conditions precedent provided for relating to either the Legal Defeasance under Section 8.02 or the Covenant Defeasance under Section 8.03 (as the case may be) have been complied with as contemplated by this Section 8.04. SECTION 8.05. Deposited Money and U.S. Government Securities to be Held in Trust; Other Miscellaneous Provisions. Subject to Section 8.06, all money and non-callable U.S. Government Securities (including the proceeds thereof) deposited with the Trustee (or other qualifying trustee, collectively for purposes of this Section 8.05, the "Trustee") pursuant to Section 8.04 in respect of the outstanding Securities shall be held in trust and applied by the Trustee, in accordance with the provisions of such Securities and this Indenture, to the payment, either directly or through any Paying Agent (including the Company or a Subsidiary Guarantor, if any, acting as Paying Agent) as the Trustee may determine, to the Holders of such Securities of all sums due and to become due thereon in respect of principal, premium, if any, and interest, but such money need not be segregated from other funds except to the extent required by law. The Company shall pay and indemnify the Trustee against any tax, fee or other charge imposed on or assessed against the cash or non-callable U.S. Government Securities deposited pursuant to Section 8.04 or the principal and interest received in respect thereof other than any such tax, fee or other charge which by law is for the account of the Holders of the outstanding Securities. Anything in this Article Eight to the contrary notwithstanding, the Trustee shall deliver or pay to the Company from time to time upon the Company's request any money or non-callable U.S. Government Securities held by it as provided in Section 8.04 which, in the opinion of a nationally recognized firm of independent public accountants expressed in a written certification thereof delivered to the Trustee (which may be the opinion delivered under Section 8.04(a)), are in excess of the amount thereof which would then be required to be deposited to effect an equivalent Legal Defeasance or Covenant Defeasance. SECTION 8.06. Repayment to Company. Any money deposited with the Trustee or any Paying Agent, or then held by the Company, in trust for the payment of the principal of, premium, if any, or interest on any Security which is not subject to the last paragraph of Section 8.05 and has remained unclaimed for one year after such principal, and premium, if any, or interest has become due and payable shall be paid to the Company on its request or (if then held by the Company) shall be discharged from such trust; and the Holder of such Securities shall thereafter, as an unsecured general creditor, look only to the Company for payment thereof, and all liability of the Trustee or such Paying Agent with respect to such trust money, and all liability of the Company as trustee thereof, shall thereupon cease; provided, however, that the Trustee or such Paying Agent, before being required to make any such repayment, may at the expense of the Company cause to be published once, in the New York Times and The Wall Street Journal (national edition), notice that such money remains unclaimed and that, after a date specified therein, which shall not be less than 30 days from the date of such publication, any unclaimed balance of such money then remaining will be repaid to the Company. -43- 50 SECTION 8.07. Reinstatement. If the Trustee or Paying Agent is unable to apply any U.S. Legal Tender or non-callable U.S. Government Securities in accordance with Section 8.02 or 8.03, as the case may be, by reason of any order or judgment of any court or governmental authority enjoining, restraining, or otherwise prohibiting such application, then the Company's obligations under this Indenture and the Securities shall be revived and reinstated as though no deposit had occurred pursuant to Section 8.02 or 8.03 until such time as the Trustee or Paying Agent is permitted to apply all such money in accordance with Section 8.02 or 8.03, as the case may be; provided, however, that, if the Company makes any payment of principal of, premium, if any, or interest on any Security following the reinstatement of its obligations, the Company shall be subrogated to the rights of the Holders of such Securities to receive such payment from the money held by the Trustee or Paying Agent.

After an amendment or waiver under this Section becomes effective, the Company shall mail to the Holders of each Security affected thereby a notice briefly describing the amendment or waiver. Any failure of the Company to mail such notice, or any defect therein, shall not, however, in any way impair or affect the validity of any such supplemental indenture. SECTION 9.02.

Except as provided below in this Section 9.02, the Company, the Subsidiary Guarantors and the Trustee may amend this Indenture or the Securities with the written consent (including consents obtained in connection with a tender offer or exchange offer for Securities or a solicitation of consents in respect of Securities, provided that in each case such offer or solicitation is made to all Holders of then outstanding Securities on equal terms) of the Holders of at least a majority of the principal amount of the outstanding Securities. Upon the request of the Company and the Subsidiary Guarantors, accompanied by a Board Resolution of the Company and each Subsidiary Guarantor authorizing the execution of any such supplemental indenture, and upon the filing with the Trustee of evidence of the consent of the Holders as aforesaid, and upon receipt by the Trustee of the -44- 51 Opinion of Counsel described in Section 9.06, the Trustee shall join with the Company and the Subsidiary Guarantors in the execution of such supplemental indenture. It shall not be necessary for the consent of the Holders under this Section to approve the particular form of any proposed amendment or waiver, but it shall be sufficient if such consent approves the substance thereof. The Holders of a majority of the principal amount of the outstanding Securities may waive compliance in a particular instance by the Company or the Subsidiary Guarantors with any provision of this Indenture or the Securities (including waivers obtained in connection with a tender offer or exchange offer for Securities or a solicitation of consents in respect of Securities, provided that in each case such offer or solicitation is made to all Holders of the then outstanding Securities on equal terms). However, without the consent of each Holder affected, an amendment or waiver under this Section may not: (1) reduce the percentage of principal amount of Securities whose Holders must consent to an amendment, supplement or waiver of any provision of this Indenture or the Securities; (2) reduce the rate or change the time for payment of interest, including default interest, on the Securities; (3) reduce the principal amount of any Security or change the Maturity Date of the Securities; (4) reduce the redemption price, including premium, if any, payable upon the redemption of any Security or change the time at which any Security may be redeemed; (5) reduce the repurchase price, including premium, if any, payable upon the repurchase of any Security pursuant to Sections 4.11 or 4.16, or change the time at which any Security may or shall be repurchased thereunder; (6) waive a Default or Event of Default in the payment of the principal of, premium, if any, or interest on the Securities; (7) make any Security payable in money other than that stated in the Security; (8) impair the right to institute suit for the enforcement of principal of, premium, if any, or principal on any Security pursuant to Sections 6.07 or 6.08, except as limited by Section 6.06; or (9) make any change in Section 6.04 or Section 6.07 or in this sentence of this Section 9.02. The right of any Holder to participate in any consent required or sought pursuant to any provision of this Indenture (and the obligation of the Company to obtain any such consent otherwise required from such Holder) may be subject to the requirement that such Holder shall have been the Holder of record of any Securities with respect to which such consent is required or sought as of a date identified by the Trustee in a notice furnished to Holders in accordance with the terms of this Indenture. SECTION 9.03. Compliance with Trust Indenture Act. Every amendment to or supplement of this Indenture or the Securities shall comply with the TIA as then in effect. -45- 52 SECTION 9.04. Revocation and Effect of Consents. A consent to an amendment, supplement or waiver by a Holder of a Security shall bind the Holder and every subsequent Holder of a Security or portion of a Security that evidences the same debt as the consenting Holder's Security, even if notation of the consent is not made on any Security. However, until an amendment, supplement or waiver becomes effective, any such Holder or subsequent Holder may revoke the consent as to its Security or portion of a Security. For such revocation to be effective, the Trustee must receive the notice of revocation before the date the amendment, supplement or waiver becomes effective. The Company may, but shall not be obligated to, fix a record date for the purpose of determining the Holders entitled to consent to any amendment or waiver. If the Company elects to fix a record date for such purpose, the record date shall be fixed at (i) the later of 30 days prior to the first solicitation of such consent or the date of the most recent list of Holders furnished to the Trustee prior to such solicitation pursuant to Section 2.05, or (ii) such other date as the Company shall designate. If a record date is fixed, then notwithstanding the provisions of the immediately preceding paragraph, those Persons who were Holders at such record date (or their duly designated proxies), and only those Persons, shall be entitled to consent to such amendment or waiver or to revoke any consent previously given, whether or not such Persons continue to be Holders after such record date. No consent shall be valid or effective for more than 90 days after such record date unless consent from the Holders of the principal amount of Securities required hereunder for such amendment or waiver to be effective also shall have been given and not revoked within such 90-day period. After an amendment, supplement or waiver becomes effective, it shall bind every Holder unless it makes a change described in any of clauses (1) through (9) of Section 9.02. In that case the amendment, supplement or waiver shall bind each Holder of a Security who has consented to it and every subsequent Holder of a Security or portion of a Security that evidences the same debt as the consenting Holder's Security. SECTION 9.05. Notation on or Exchange of Senior Notes. If an amendment, supplement or waiver changes the terms of a Security, the Trustee may require the Holder of the Security to deliver it to the Trustee. The Trustee may place an appropriate notation on the Security about the changed terms and return it to the Holder. Alternatively, if the Company or the Trustee so determines, the Company in exchange for the Security shall issue and the Trustee shall authenticate a new Security that reflects the changed terms. SECTION 9.06. Trustee Protected. The Trustee shall sign any amendment or supplement or waiver authorized pursuant to this Article if the amendment or supplement or waiver does not adversely affect the rights of the Trustee. If it does adversely affect the rights of the Trustee, the Trustee may but need not sign it. In signing such amendment or supplement or waiver the Trustee shall be entitled to receive, and (subject to Article Seven) shall be fully protected in relying upon, an Opinion of Counsel stating that such amendment or supplement or waiver is authorized or permitted by and complies with this Indenture. The Company may not sign an amendment or supplement until the Boards of Directors of the Company and the Subsidiary Guarantors approve it. ARTICLE TEN GUARANTEES SECTION 10.01. Unconditional Guarantee. Each Subsidiary Guarantor hereby, jointly and severally, fully and unconditionally guarantees, as principal obligor and not only as surety (such guarantee to be referred to herein as the "Guarantee"), to each Holder and to the Trustee the due and punctual payment of the principal of, premium, if any, and interest on the Securities and all other amounts due and payable under this Indenture and the Securities by the Company whether at maturity, by acceleration, redemption, repurchase or otherwise, including, without limitation, interest on the overdue principal of, -46- 53 premium, if any, and interest on the Securities, to the extent lawful, all in accordance with the terms hereof and thereof; subject, however, to the limitations set forth in Section 10.05. Failing payment when due of any amount so guaranteed for whatever reason, the Subsidiary Guarantors will be jointly and severally obligated to pay the same immediately. Each Subsidiary Guarantor hereby agrees that its obligations hereunder shall be unconditional, irrespective of the validity, regularity or enforceability of the Securities or this Indenture, the absence of any action to enforce the same, any waiver or consent by any Holder of the Securities with respect to any provisions hereof or thereof, the recovery of any judgment against the Company, any action to enforce the same or any other circumstance which might otherwise constitute a legal or equitable discharge or defense of a guarantor. Each Subsidiary Guarantor hereby waives diligence, presentment, demand of payment, filing of claims with a court in the event of insolvency or bankruptcy of the Company, any right to require a proceeding first against the Company, protest, notice and all demands whatsoever and covenants that this Guarantee will not be discharged except by complete performance of the obligations contained in the Securities, this Indenture and in this Guarantee.

Each Subsidiary Guarantor agrees it shall not be entitled to any right of subrogation in relation to the Holders in respect of any obligations guaranteed hereby until payment in full of all obligations guaranteed hereby. Each Subsidiary Guarantor further agrees that, as between each Subsidiary Guarantor, on the one hand, and the Holders and the Trustee, on the other hand, (x) the maturity of the obligations guaranteed hereby may be accelerated as provided in Article Six for the purposes of this Guarantee, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the obligations guaranteed hereby, and (y) in the event of any acceleration of such obligations as provided in Article Six, such obligations (whether or not due and payable) shall forthwith become due and payable by each Subsidiary Guarantor for the purpose of this Guarantee. SECTION 10.02. Subsidiary Guarantors May Consolidate, etc., on Certain Terms. (a) Subject to paragraph (b) of this Section 10.02, no Subsidiary Guarantor may consolidate or merge with or into (whether or not such Subsidiary Guarantor is the surviving entity or Person) another corporation, entity or Person unless (i) the entity or Person formed by or surviving any such consolidation or merger (if other than such Subsidiary Guarantor) assumes all the obligations of such Subsidiary Guarantor pursuant to a supplemental indenture, in a form reasonably satisfactory to the Trustee, under the Securities and this Indenture, (ii) immediately after such transaction, no Default or Event of Default exists, (iii) such Subsidiary Guarantor or the entity or Person formed by or surviving any such consolidation or merger will have Consolidated Tangible Net Worth (immediately after the transaction) equal to or greater than the Consolidated Tangible Net Worth of such Subsidiary Guarantor immediately preceding the transaction and (iv) the Company will, at the time of such transaction after giving pro forma effect thereto as if such transaction had occurred at the beginning of the applicable Reference Period, be permitted to incur at least $1.00 of additional Indebtedness pursuant to Section 4.09(a). In connection with any consolidation or merger contemplated by this Section 10.02, the Company shall deliver to the Trustee prior to the consummation of the proposed transaction an Officers' Certificate to the foregoing effect and an Opinion of Counsel stating that the proposed transaction and such supplemental indenture comply with this Indenture. This Section 10.02(a) will not prohibit a merger between Subsidiary Guarantors or a merger between the Company and a Subsidiary Guarantor. (b) In the event of a sale or other disposition of all or substantially all of the assets of any Subsidiary Guarantor, by way of merger, consolidation or otherwise, or a sale or other disposition of all of the Capital Stock of such Subsidiary Guarantor, then such Subsidiary Guarantor (in the event of a sale or other disposition, by way of such a merger, consolidation or otherwise, of all of the Capital Stock of such Subsidiary Guarantor) or the corporation acquiring the property (in the event of a sale or other disposition of all or substantially all of the assets of such Subsidiary Guarantor) will be released and relieved of any obligations under its Guarantees; provided that in the event such sale or disposition constitutes an Asset Sale, the Net Available Proceeds of such sale or other disposition are applied in accordance with the provisions of this Indenture described under Section 4.11. -47- 54 SECTION 10.03. Addition of Subsidiary Guarantors. (a) The Company agrees to cause each Subsidiary that shall become a Restricted Subsidiary after the Issue Date to execute and deliver a supplemental indenture pursuant to which such Restricted Subsidiary shall guarantee the payment of the Securities pursuant to the terms hereof. (b) Any Person that was not a Subsidiary Guarantor on the Issue Date may become a Subsidiary Guarantor by executing and delivering to the Trustee (i) a supplemental indenture in form and substance satisfactory to the Trustee, which subjects such Person to the provisions (including the representations and warranties) of this Indenture as a Subsidiary Guarantor and (ii) an Opinion of Counsel and Officers' Certificate to the effect that such supplemental indenture has been duly authorized and executed by such Person and constitutes the legal, valid and binding obligation of such Person (subject to such customary exceptions concerning creditors' rights and equitable principles as may be acceptable to the Trustee in its discretion and provided that no opinion need be rendered concerning the enforceability of the Guarantee). SECTION 10.04. Release of a Subsidiary Guarantor. Upon the sale or disposition of a Subsidiary Guarantor (or substantially all of its assets), which is otherwise in compliance with the terms of this Indenture, including but not limited to the provisions of Section 10.02, such Subsidiary Guarantor shall be deemed released from all of its Guarantee and related obligations in this Indenture. The Trustee shall deliver an appropriate instrument evidencing such release upon receipt of a request by the Company accompanied by an Officers' Certificate and an Opinion of Counsel certifying that such sale or other disposition was made by the Company in accordance with the provisions of this Indenture. Any Subsidiary Guarantor not so released remains liable for the full amount of principal of and interest on the Securities as provided in this Article Ten. SECTION 10.05. Limitation of Subsidiary Guarantor's Liability. Each Subsidiary Guarantor, and by its acceptance hereof each Holder, hereby confirms that it is the intention of all such parties that the guarantee by such Subsidiary Guarantor pursuant to its Guarantee not constitute a fraudulent transfer or conveyance for purposes of any federal, state or foreign law. To effectuate the foregoing intention, the Holders and each Subsidiary Guarantor hereby irrevocably agree that the obligations of each Subsidiary Guarantor under the Guarantee shall be limited to the maximum amount as will, after giving effect to all other contingent and fixed liabilities of such 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 Guarantee or pursuant to Section 10.06, result in the obligations of such Subsidiary Guarantor under the Guarantee not constituting a fraudulent conveyance or fraudulent transfer under federal, state or foreign law. This Section 10.05 is for the benefit of the creditors of each Subsidiary Guarantor, and, for purposes of applicable fraudulent transfer and fraudulent conveyance law, any Indebtedness of a Subsidiary Guarantor pursuant to a Bank Credit Facility shall be deemed to have been incurred prior to the incurrence by such Subsidiary Guarantor of its liability under the Guarantee. SECTION 10.06. Contribution. In order to provide for just and equitable contribution among the Subsidiary Guarantors, the Subsidiary Guarantors agree, inter se, that in the event any payment or distribution is made by any Subsidiary Guarantor (a "Funding Guarantor") under the Guarantee, such Funding Guarantor shall be entitled to a contribution from each other Subsidiary Guarantor in a pro rata amount based on the Adjusted Net Assets of each Subsidiary Guarantor (including the Funding Guarantor) for all payments, damages and expenses incurred by the Funding Guarantor in discharging the Company's obligations with respect to the Securities or any other Subsidiary Guarantor's obligations with respect to the Guarantee. SECTION 10.07. Execution and Delivery of Guarantee. To further evidence the Guarantees set forth in Section 10.01, each Subsidiary Guarantor hereby agrees that a notation relating to such Guarantee, in substantially the form of Exhibit A-1, shall be endorsed on each Security -48- 55 authenticated and delivered by the Trustee and executed by either manual or facsimile signature of one Officer of each Subsidiary Guarantor. Each of the Subsidiary Guarantors hereby agrees that its Guarantee set forth in Section 10.01 shall remain in full force and effect notwithstanding any failure to endorse on each Security a notation relating to such Guarantee. If an Officer of a Subsidiary Guarantor whose signature is on this Indenture or a Security no longer holds that office at the time the Trustee authenticates such Security or at any time thereafter, such Subsidiary Guarantor's Guarantee of such Security shall be valid nevertheless. The delivery of any Security by the Trustee, after the authentication thereof hereunder, shall constitute due delivery of any Guarantee set forth in this Indenture on behalf of the Subsidiary Guarantor. SECTION 10.08. Severability. In case any provision of this Guarantee shall be invalid, illegal or unenforceable, that portion of such provision that is not invalid, illegal or unenforceable shall remain in effect, and the validity, legality, and enforceability of the remaining provisions shall not in any way be affected or impaired thereby.
