Section 1.06. Compliance Certificates and Opinions. Upon any application or request by the Company or by any other obligor upon the Notes to the Trustee to take any action under any provision of this Indenture, the Company or such other obligor upon the Notes, as the case may be, shall furnish to the Trustee such certificates and opinions as may be required under the TIA.

Where any Person is required to make, give or execute two or more applications, requests, consents, certificates, statements, opinions or other instruments under this Indenture, they may, but need not, be consolidated and form one instrument.

Section 1.08. Acts of Noteholders; Record Dates. (a) Any request, demand, authorization, direction, notice, consent, waiver or other action provided by this Indenture to be given or taken by Holders may be embodied in and evidenced by one or more instruments of substantially similar tenor signed by such Holders in person or by agent duly appointed in writing; and, except as herein otherwise expressly provided, such action shall become effective when such instrument or instruments are delivered to the Trustee, and, where it is hereby expressly required, to the Company. Such instrument or instruments (and the action embodied therein and evidenced thereby) are herein sometimes referred to as the “Act” of the Holders signing such instrument or instruments. Proof of execution of any such instrument or of a writing appointing any such agent shall be sufficient for any purpose of this Indenture and (subject to Section 7.01) conclusive in favor of the Trustee, the Company and any other obligor upon the Notes, if made in the manner provided in this Section 1.08.

(b) The fact and date of the execution by any Person of any such instrument or writing may be proved by the affidavit of a witness of such execution or by the certificate of any notary public or other officer authorized by law to take acknowledgments of deeds, certifying that the individual signing such instrument or writing acknowledged to him the execution thereof. Where such execution is by an officer of a corporation or a member of a partnership or other entity, on behalf of such corporation or

partnership or other entity, such certificate or affidavit shall also constitute sufficient proof of such Person’s authority. The fact and date of the execution of any such instrument or writing, or the authority of the person executing the same, may also be proved in any other manner that the Trustee deems sufficient.

(d) Any request, demand, authorization, direction, notice, consent, waiver or other action by the Holder of any Note shall bind the Holder of every Note issued upon the transfer thereof or in exchange therefor or in lieu thereof, in respect of anything done or suffered to be done by the Trustee, the Company or any other obligor on the Notes in reliance thereon, whether or not notation of such action is made upon such Note.

(e) (i) The Company may set any day as a record date for the purpose of determining the Holders of Outstanding Notes entitled to give, make or take any request, demand, authorization, direction, notice, consent, waiver or other action provided or permitted by this Indenture to be given, made or taken by Holders, provided that the Company may not set a record date for, and the provisions of this paragraph shall not apply with respect to, the giving or making of any notice, declaration, request or direction referred to in Section 1.08(e)(ii). If any record date is set pursuant to this paragraph, the Holders of Outstanding Notes on such record date (or their duly designated proxies), and no other Holders, shall be entitled to take the relevant action, whether or not such Persons remain Holders after such record date; provided that no such action shall be effective hereunder unless taken on or prior to the applicable Expiration Date by Holders of the requisite principal amount of Outstanding Notes on such record date. Nothing in this paragraph shall be construed to prevent the Company from setting a new record date for any action for which a record date has previously been set pursuant to this paragraph (whereupon the record date previously set shall automatically and with no action by any Person be canceled and of no effect), and nothing in this paragraph shall be construed to render ineffective any action taken by Holders of the requisite principal amount of Outstanding Notes on the date such action is taken. Promptly after any record date is set pursuant to this paragraph, the Company, at its own expense, shall cause notice of such record date, the proposed action by Holders and the applicable Expiration Date to be given to the Trustee in writing and to each Holder in the manner set forth in Section 1.10.

(ii) The Trustee may set any day as a record date for the purpose of determining the Holders of Outstanding Notes entitled to join in the giving or making of (w) any Notice of Default, (x) any declaration of acceleration referred to in Section 6.02, (y) any request to institute proceedings referred to in Section 6.06(b) or (z) any direction referred to in Section 6.05, in each case with respect to Notes. If any record date is set pursuant to this paragraph, the Holders of Outstanding Notes on such record date, and no other Holders, shall be entitled to join in such notice, declaration, request or direction, whether or not such Holders remain Holders after such record date; provided that no such action shall be effective hereunder unless taken on or prior to the applicable Expiration Date by Holders of the requisite principal amount of Outstanding Notes on such record date. Nothing in this paragraph shall be construed to prevent the Trustee from setting a new record date for any action for which a record date has previously been set pursuant to this paragraph (whereupon the record date previously set shall automatically and with no action by any Person be canceled and of no effect), and nothing in this paragraph shall be construed to render ineffective any action taken by Holders of the requisite principal amount of Outstanding Notes on the date such action is taken. Promptly after any record date is set pursuant to this paragraph, the Trustee, at the expense of the Company, shall cause notice of such record date, the proposed action by Holders and the applicable Expiration Date to be given to the Company in writing and to each Holder in the manner set forth in Section 1.10.

(iii) With respect to any record date set pursuant to this Section 1.08, the party hereto that sets such record dates may designate any day as the “Expiration Date” and from time to time may change the Expiration Date to any earlier or later day; provided that no such change shall be effective unless notice of the proposed new Expiration Date is given to the Company or the Trustee (whichever such party is not setting a record date pursuant to this Section l.08(e)) in writing, and to each Holder in the manner set forth in Section 1.10, on or prior to the existing Expiration Date. If an Expiration Date is not designated with respect to any record date set pursuant to this Section, the party hereto that set such record date shall be

deemed to have initially designated the 180th day after such record date as the Expiration Date with respect thereto, subject to its right to change the Expiration Date as provided in this paragraph. Notwithstanding the foregoing, no Expiration Date shall be later than the 180th day after the applicable record date.

(iv) Without limiting the foregoing, a Holder entitled hereunder to take any action hereunder with regard to any particular Note may do so with regard to all or any part of the principal amount of such Note or by one or more duly appointed agents each of which may do so pursuant to such appointment with regard to all or any part of such principal amount.

Section 1.09. Notices, Etc., to Trustee and Company. Any request, demand, authorization, direction, notice, consent, waiver or Act of Holders or other document provided or permitted by this Indenture to be made upon, given or furnished to, or filed with,

(a) the Trustee by any Holder or by the Company or any other obligor upon the Notes shall be sufficient for every purpose hereunder if made, given, furnished or filed in writing to or with the Trustee at the Corporate Trust Office (telephone: ; facsimile: ), or at any other address furnished in writing to the Company by the Trustee, or

(b) the Company by the Trustee or by any Holder shall be sufficient for every purpose hereunder if in writing and delivered in person or mailed, first-class postage prepaid, to the Company at One Houston Center, Suite 700, 1221 McKinney, Houston, Texas 77010, Attention: General Counsel (facsimile: (713) 309-2143), with copies to Baker Botts L.L.P. at 910 Louisiana, Houston, Texas 77002, Attention: Stephen A.

Section 1.10. Notices to Holders; Waivers. Where this Indenture provides for notice to Holders of any event, such notice shall be deemed to have been given upon the mailing by first class mail, postage prepaid, of such notices to Holders at their registered addresses as recorded in the Register, not later than the latest date, and not earlier than the earliest date, prescribed herein for the giving of such notice. In any case where notice to Holders is given by mail, neither the failure to mail such notice, nor any defect in any notice so mailed, to any particular Holder shall affect the sufficiency of such notice with respect to other Holders.

Where this Indenture provides for notice in any manner, such notice may be waived in writing by the Person entitled to receive such notice, either before or after the event, and such waiver shall be the equivalent of such notice. Waivers of notice by Holders shall be filed with the Trustee, but such filing shall not be a condition precedent to the validity of any action taken in reliance upon such waiver.

In case, by reason of the suspension of regular mail service, or by reason of any other cause, it shall be impossible to mail notice of any event as required by any provision of this Indenture, then such notification as shall be made with the approval of the Trustee (such approval not to be unreasonably withheld) shall constitute a sufficient notification for every purpose hereunder.

Section 1.11. Effect of Headings and Table of Contents. The Article and Section headings herein and the Table of Contents are for convenience only and shall not affect the construction hereof.

Section 1.12. Successors and Assigns. All covenants and agreements in this Indenture by the Company shall bind its respective successors and assigns, whether so expressed or not.

Section 1.13. Separability Clause. In case any provision in this Indenture or in the Notes shall be invalid, illegal or unenforceable, the validity, legality and enforceability of the remaining provisions shall not in any way be affected or impaired thereby.

Section 1.14. Benefits of Indenture. Nothing in this Indenture or in the Notes, express or implied, shall give to any Person, other than the parties hereto and their successors hereunder, any Paying Agent and the Holders, any benefit or any legal or equitable right, remedy or claim under this Indenture.

Section 1.15. Governing Law. THIS INDENTURE, THE NOTES AND THE SUBSIDIARY GUARANTEES SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK, WITHOUT GIVING EFFECT TO ANY PRINCIPLES OF CONFLICT OF LAWS TO THE EXTENT THAT THE APPLICATION OF THE LAW OF ANOTHER JURISDICTION WOULD BE REQUIRED THEREBY. TO THE EXTENT PERMITTED BY LAW, THE TRUSTEE, THE COMPANY, THE SUBSIDIARY GUARANTORS, ANY OTHER OBLIGORS IN RESPECT OF THE NOTES AND (BY THEIR ACCEPTANCE OF THE NOTES) THE HOLDERS, AGREE TO SUBMIT TO THE NON-EXCLUSIVE JURISDICTION OF ANY UNITED STATES FEDERAL OR STATE COURT LOCATED IN THE BOROUGH OF MANHATTAN, IN THE CITY OF NEW YORK IN ANY ACTION OR PROCEEDING ARISING OUT OF OR RELATING TO THIS INDENTURE OR THE NOTES.

In any case where any Interest Payment Date, Redemption Date or Stated Maturity of any Note shall not be a Business Day, then (notwithstanding any other provision of this Indenture or of the Notes) payment of interest or principal and premium (if any) need not be made on such date, but may be made on the next succeeding Business Day with the same force and effect as if made on the Interest Payment Date or Redemption Date, or at the Stated Maturity.

Section 1.17. No Personal Liability of Directors, Officers, Employees, Incorporators and Stockholders. No director, officer, employee, incorporator, shareholder or other holder of Equity Interests of the Company or the Subsidiary Guarantors, as such, shall have any liability for any obligations of the Company or the Subsidiary Guarantors under the Notes, the Subsidiary Guarantees, the Indenture or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each Holder of Notes by accepting a Note waives and releases all such liability. The waiver and release are part of the consideration for the issuance of the Notes.

No Note shall be entitled to any benefit under this Indenture or be valid or obligatory for any purpose, unless there appears on such Note a certificate of authentication substantially in the form provided for herein executed by the Trustee by manual signature, and such certificate upon any Note shall be conclusive evidence, and the only evidence, that such Note has been duly authenticated and delivered hereunder.

Until so exchanged the temporary Notes shall in all respects be entitled to the same benefits under this Indenture as definitive Notes of the same series and tenor.

Section 3.05. Registration, Registration of Transfer and Exchange. The Company shall cause to be kept at the Corporate Trust Office of the Trustee a register (the register maintained in such office and in any other office or agency of the Company in a Place of Payment being herein sometimes collectively referred to as the “Register”) in which, subject to such reasonable regulations as it may prescribe, the Company shall provide for the registration of Notes and of transfers of Notes. The Trustee is hereby appointed “Registrar” for the purpose of registering Notes and transfers of Notes as herein provided.

Upon surrender for transfer of any Note at the office or agency of the Company in a Place of Payment, in compliance with all applicable requirements of this Indenture and applicable law, the Company shall execute, and the Trustee shall authenticate and deliver, in the name of the designated transferee or transferees, one or more new Notes, of any authorized denominations and of a like aggregate principal amount.

At the option of the Holder, Notes may be exchanged for other Notes, of any authorized denominations and of a like tenor and aggregate principal amount, upon surrender of the Notes to be exchanged at such office or agency. Whenever any Notes are so surrendered for exchange, the Company shall execute, and the Trustee shall authenticate and deliver, the Notes that the Holder making the exchange is entitled to receive.

All Notes issued upon any registration of transfer or exchange of Notes shall be the valid obligations of the Company, evidencing the same debt, and entitled to the same benefits under this Indenture, as the Notes surrendered upon such registration of transfer or exchange.

Every Note presented or surrendered for registration of transfer or exchange shall (if so required by the Company or the Registrar) be duly endorsed, or be accompanied by a written instrument of transfer, in form satisfactory to the Company and the Registrar duly executed, by the Holder thereof or such Holder’s attorney duly authorized in writing.

No service charge shall be made for any registration of transfer or exchange or redemption of Notes, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection with any registration of transfer or exchange of Notes under this Section 3.05.

Section 3.06. Mutilated, Destroyed, Lost and Stolen Notes. If (a) any mutilated Note is surrendered to the Trustee, or the Company and the Trustee receive evidence to their satisfaction of the destruction, loss or theft of any Note, and (b) there is delivered to the Company and the Trustee such security or indemnity as may be required by them to save each of them harmless, then, in the absence of

notice to the Company or the Trustee that such Note has been acquired by a bona fide purchaser, the Company shall execute and upon receipt of an Authentication Order the Trustee shall authenticate and deliver, in exchange for or in lieu of any such mutilated, destroyed, lost or stolen Note, a new Note of like tenor and principal amount, bearing a number not contemporaneously Outstanding.

In case any such mutilated, destroyed, lost or stolen Note has become or is about to become due and payable, the Company in its discretion may, instead of issuing a new Note, pay such Note.

Upon the issuance of any new Note under this Section 3.06, the Company may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other expenses (including the fees and expenses of the Trustee) connected therewith.

Every new Note issued pursuant to this Section 3.06 in lieu of any mutilated, destroyed, lost or stolen Note shall constitute an original additional contractual obligation of the Company, whether or not the mutilated, destroyed, lost or stolen Note shall be at any time enforceable by anyone, and shall be entitled to all the benefits of this Indenture equally and ratably with any and all other Notes duly issued hereunder.

The provisions of this Section 3.06 are exclusive and shall preclude (to the extent lawful) all other rights and remedies with respect to the replacement or payment of mutilated, destroyed, lost or stolen Notes.

Section 3.07. Payment of Interest Rights Preserved. Interest on any Note that is payable, and is punctually paid or duly provided for, on any Interest Payment Date shall be paid to the Person in whose name that Note (or one or more Predecessor Notes) is registered at the close of business on the Regular Record Date for such interest specified in Section 3.01.

Any interest on any Note that is payable, but is not punctually paid or duly provided for, on any Interest Payment Date (herein called “Defaulted Interest”) shall forthwith cease to be payable to the registered Holder on the relevant Regular Record Date by virtue of having been such Holder; and such Defaulted Interest shall be paid by the Company, as provided in 3.07(a) or 3.07(b) below:

(a) The Company may elect to make payment of any Defaulted Interest to the Persons in whose names the Notes (or their respective Predecessor Notes) are registered at the close of business on a Special Record Date for the payment of such Defaulted Interest, which shall be fixed in the following manner. The Company shall notify the Trustee in writing of the amount of Defaulted Interest proposed to be paid on each Note and the date of the proposed payment, and at the same time the Company shall deposit with the Trustee an amount of money equal to the aggregate amount proposed to be paid in respect of such Defaulted Interest or shall make arrangements reasonably satisfactory to the Trustee for such deposit prior to the date of the proposed payment, such money when deposited to be held in trust for the benefit of the Persons entitled to such Defaulted Interest as provided in this Section 3.07(a). Thereupon the Trustee shall fix a Special Record Date for the payment of such Defaulted Interest which shall be not more than 15 nor less than 10 days prior to the date of the proposed payment and not less than 10 days after the receipt by the Trustee of the notice of the proposed payment. The Trustee shall promptly notify the Company of such Special Record Date and, in the name and at the expense of the Company, shall cause notice of the proposed payment of such Defaulted Interest, the amount thereof and the Special Record Date and payment date therefor to be mailed, first class postage prepaid, to each Holder at such Holder’s address as it appears in the Register, not less than 10 days prior to such Special Record Date. Notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor having been so mailed, such Defaulted Interest shall be paid to the Persons in whose names the Notes (or their respective Predecessor Notes) are registered on such Special Record Date and shall no longer be payable pursuant to the following 3.07(b).

(b) The Company may make payment of any Defaulted Interest in any other lawful manner not inconsistent with the requirements of any securities exchange on which the Notes may be listed, and upon such notice as may be required by such exchange, if, after notice given by the Company to the

Trustee of the proposed payment pursuant to this clause (b), such payment shall be deemed practicable by the Trustee.

Subject to the foregoing provisions of this Section 3.07, each Note delivered under this Indenture upon registration of transfer of or in exchange for or in lieu of any other Note shall carry the rights to interest accrued and unpaid, and to accrue, that were carried by such other Note.

Section 3.08. Persons Deemed Owners. Prior to due presentment of a Note for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name such Note is registered as the owner of such Note for the purpose of receiving payment of principal of (and premium, if any, on) and (subject to Section 3.07) interest on such Note and for all other purposes whatsoever, whether or not such Note be overdue, and none of the Company, the Subsidiary Guarantors, the Trustee or any agent of the Company, the Subsidiary Guarantors or the Trustee shall be affected by notice to the contrary.

Section 3.09. Cancellation. All Notes surrendered for payment, redemption, registration of transfer or exchange shall, if surrendered to any Person other than the Trustee, be delivered to the Trustee and, if not already canceled, shall be promptly canceled by it. The Company may at any time deliver to the Trustee for cancellation any Notes previously authenticated and delivered hereunder that the Company may have acquired in any manner whatsoever, and all Notes so delivered shall be promptly canceled by the Trustee. No Notes shall be authenticated in lieu of or in exchange for any Notes canceled as provided in this Section 3.09, except as expressly permitted by this Indenture. All canceled Notes held by the Trustee shall be disposed of in accordance with the Trustee’s customary procedures.

Section 3.10. Computation of Interest. Interest on the Notes shall be computed on the basis of .

Section 3.12. CUSIP Numbers. The Company in issuing the Notes may use “CUSIP” or “CINS” numbers (if then generally in use) in addition to serial numbers, and, if so, the Trustee shall use such “CUSIP” or “CINS” numbers in addition to serial numbers in notices of redemption, repurchase or other notices to Holders as a convenience to Holders; provided that any such notice may state that no representation is made as to the correctness of such “CUSIP” or “CINS” numbers either as printed on the Notes or as contained in any notice of a redemption or repurchase and that reliance may be placed only on the serial or other identification numbers printed on the Notes, and any such redemption or repurchase shall not be affected by any defect in or omission of such numbers. The Company will promptly notify the Trustee of any change in the “CUSIP” or “CINS” numbers.

(a) Each Global Note initially shall (i) be registered in the name of the Depositary for such Global Notes or the nominee of such Depositary, and (ii) be delivered to the Trustee as custodian for such Depositary. None of the Company or the Subsidiary Guarantors, nor any of their agents shall have any responsibility or liability for any aspect of the records relating to, or payments made on account of beneficial ownership interests of, a Global Note, or for maintaining, supervising or reviewing any records relating to such beneficial ownership interests.

Members of, or participants in, the Depositary (“Agent Members”) shall have no rights under this Indenture with respect to any Global Note, and the Depositary may be treated by the Company, the Subsidiary Guarantors, the Trustee and any agent of the Company, the Subsidiary Guarantors or the Trustee as the absolute owner of such Global Note for all purposes whatsoever. Notwithstanding the foregoing, nothing herein shall prevent the Company, the Subsidiary Guarantors, the Trustee or any agent of the Company, the Subsidiary Guarantors 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 practices governing the exercise of the rights of a beneficial owner of any Note. The registered Holder of a Global Note may grant proxies and otherwise authorize any person, including Agent Members and persons that may hold interests through Agent Members, to take any action which a Holder is entitled to take under this Indenture or the Notes.

(b) Interests of beneficial owners in a Global Note may be transferred in accordance with the applicable rules and procedures of the Depositary. Transfers of a Global Note shall be limited to transfers of such Global Note in whole, but not in part, to the Depositary, its successors or their respective nominees, except that Physical Notes shall be transferred to all beneficial owners in exchange for their beneficial interests in a Global Note in the event that (A) the Depositary notifies the Company that it is unwilling or unable to continue as Depositary for the applicable Global Note and a successor depositary is not appointed by the Company within 90 days or (B) an Event of Default has occurred and is continuing and the Registrar has received a request from the Depositary. In addition, beneficial interests in a Global Note may be exchanged for Physical Notes upon request but only upon at least 20 days’ prior written notice given to the Trustee by or on behalf of the Depository in accordance with customary procedures. In connection with any transfer or exchange of a portion of the beneficial interest in any Global Note to beneficial owners for Physical Notes pursuant to this Section 3.13(b), the Registrar shall record on its books and records (and make a notation on the Global Note of) the date and a decrease in the principal amount of such Global Note in an amount equal to the beneficial interest in the Global Note being transferred, and the Company shall execute, and the Trustee shall authenticate and deliver, one or more Physical Notes of like tenor and principal amount of authorized denominations. In connection with a transfer of an entire Global Note to beneficial owners pursuant to this paragraph (b), the applicable Global Note shall be deemed to be surrendered to the Trustee for cancellation, and the Company shall execute, and the Trustee shall authenticate and deliver, to each beneficial owner identified by the Depositary in exchange for its beneficial interest in the applicable Global Note, an equal aggregate principal amount at maturity of Physical Notes of authorized denominations.

(c) Any beneficial interest in one of the Global Notes that is transferred to a person who takes delivery in the form of an interest in another Global Note will, upon transfer, cease to be an interest in such Global Note and become an interest in the other Global Note and, accordingly, will thereafter be subject to all procedures applicable to beneficial interests in such other Global Note for as long as it remains such an interest.

(d) The Company, the Subsidiary Guarantors, any other obligor upon the Notes or the Trustee, in the discretion of any of them, may treat as the Act of a Holder any instrument or writing of any Person that is identified by the Depositary as the owner of a beneficial interest in the Global Note, provided that the fact and date of the execution of such instrument or writing is proved in accordance with Section 1.08(b).

Section 4.01. Payment of Principal, Premium and Interest. (a) The Company will duly and punctually pay the principal of (and premium, if any) and interest on the Notes in accordance with the terms of the Notes and this Indenture. An installment of principal (and premium, if any) or interest shall be considered paid on the date it is due if the Trustee or Paying Agent or Paying Agents hold on that date money designated for and sufficient to pay the installment.

(b) Payments (including principal, premium, if any, and interest) in respect of the Notes represented by the Global Notes, the Holder of which has given wire transfer instructions on or prior to the relevant record date, shall be made by wire transfer of immediately available funds to the accounts specified by the Global Note Holder. With respect to Physical Notes, the Company will make all payments of principal, premium, if any, and interest at the office or agency maintained by the Company in The City of New York referred to in Section 4.02 or, at the option of the Company, by mailing a check to each such Holder’s registered address.

Section 4.02. Maintenance of Office or Agency. The Company will maintain in the Borough of Manhattan, The City of New York an office or agency where Notes may be presented or surrendered for payment, where Notes may be surrendered for transfer or exchange and where notices and demands to or upon the Company in respect of the Notes and this Indenture may be served. The Company will give prompt written notice to the Trustee of the location, and of any change in the location, of such office or agency. If at any time the Company shall fail to maintain such 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 Corporate Trust Office of the Trustee. The Company hereby designates the Corporate Trust Office as an initial Place of Payment and as such office of the Company in the Borough of Manhattan, The City of New York, and appoints the Trustee as its agent to receive all such presentations, surrenders, notices and demands so long as such Corporate Trust Office remains a Place of Payment.

Section 4.03. Money for Payments to Be Held in Trust. If the Company shall at any time act as its own Paying Agent, it will, on or before each due date of the principal of (and premium, if any) or interest on, any of the Notes, segregate and hold in trust for the benefit of the Persons entitled thereto a sum sufficient to pay the principal (and premium, if any) or interest so becoming due until such sums shall be paid to such Persons or otherwise disposed of as herein provided, and will promptly notify the Trustee of its action or failure so to act.

If the Company is not acting as its own Paying Agent, it will, prior to each due date of the principal of (and premium, if any) or interest on, any Notes, deposit with a Paying Agent a sum sufficient to pay the principal (and premium, if any) or interest so becoming due, such sum to be held in trust for the benefit of the Persons entitled to such principal, premium or interest, and (unless such Paying Agent is the Trustee) the Company will promptly notify the Trustee of its action or failure so to act.

If the Company is not acting as its own Paying Agent, the Company will cause any Paying Agent other than the Trustee to execute and deliver to the Trustee an instrument in which such Paying Agent shall agree with the Trustee, subject to the provisions of this Section 4.03, that such Paying Agent will:

(a) hold all sums held by it for the payment of principal of (and premium, if any) or interest on Notes in trust for the benefit of the Persons entitled thereto until such sums shall be paid to such Persons or otherwise disposed of as herein provided;

(b) give the Trustee notice of any default by the Company (or any other obligor upon the Notes) in the making of any such payment of principal (and premium, if any) or interest;

(c) at any time during the continuance of any such default, upon the written request of the Trustee, forthwith pay to the Trustee all sums so held in trust by such Paying Agent; and

(d) acknowledge, accept and agree to comply in all respects with the provisions of this Indenture and TIA relating to the duties, rights and liabilities of such Paying Agent.

The Company may at any time, for the purpose of obtaining the satisfaction and discharge of this Indenture or for any other purpose, pay, or by Company Order direct any Paying Agent to pay, to the Trustee all sums held in trust by the Company or such Paying Agent, such sums to be held by the Trustee upon the same trusts as those upon which such sums were held by the Company or such Paying Agent; and, upon such payment by any Paying Agent to the Trustee, such Paying Agent shall be released from all further liability with respect to such money.

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 (and premium, if any) or interest on any Note and remaining unclaimed for two years after such principal (and premium, if any) or interest has become due and payable shall be paid in the appropriate proportion to the Company upon a Company Request, or (if then held by the Company) shall be discharged from such trust; and the Holder of such Note 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.

Section 4.04. SEC Reports. (a) Whether or not required by the rules and regulations of the SEC, so long as any Notes issued hereunder are outstanding, the Company will furnish to the Trustee, promptly after filing with the SEC, (i) all quarterly and annual financial information that would be required to be contained in a filing with the SEC on Forms 10-Q and 10-K if the Company were required to file such Forms, including a “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and, with respect to the annual information only, a report thereon by the Company’s certified independent accountants and (ii) all current reports that would be required to be filed with the SEC on Form 8-K if the Company were required to file such reports. In addition, whether or not required by the rules and regulations of the SEC, the Company will file a copy of all such information and reports with the SEC for public availability and make such information available to securities analysts and prospective investors upon request.

(b) The Company shall post on its website, promptly after filing with the SEC, copies of all such information and reports provided to the Trustee pursuant to Section 4.04(a).

(d) The Company intends to file the information and reports referred to in Section 4.04(a) with the SEC in electronic form using the SEC’s Electronic Data Gathering, Analysis and Retrieval (“EDGAR”) system. The Company shall notify the Trustee of each such filing. The Trustee is hereby authorized and directed to access the EDGAR system for purposes of retrieving the reports so filed. Compliance with the foregoing shall constitute delivery by the Company of such reports to the Trustee in compliance with this Section 4.04. The Trustee shall have no duty to search for or obtain any electronic or other filings that the Company makes with the SEC, regardless of whether such filings are periodic, supplemental or otherwise. Delivery of such reports, information and documents to the Trustee pursuant to this Section 4.04 is for informational purposes only and the Trustee’s receipt of such shall not constitute constructive notice of any information contained therein or determinable from information contained therein, including the Company’s compliance with any of its covenants hereunder (as to which the Trustee is entitled to rely exclusively on Officer’s Certificates).

Section 4.05. Certificates to Trustee. (a) The Company will deliver to the Trustee within 120 days after the end of each fiscal year of the Company a certificate from the principal executive, financial or accounting officer of the Company stating that such officer has conducted or supervised a review of the activities of the Company and its Restricted Subsidiaries and the Company’s and its Restricted Subsidiaries’ performance under this Indenture and that, based upon such review, to the best of such officer’s knowledge, the Company has fulfilled all obligations thereunder or, if there has been a default in the fulfillment of any such obligation (determined without regard to any period of grace or requirement of notice provided in this Indenture), specifying each such default and the nature and status thereof.

(b) The Company will deliver to the Trustee, as soon as possible and in any event within 30 days after the Company becomes aware of an Event of Default or a Default, an Officer’s Certificate setting forth the details of such Event of Default or Default, and the action which the Company proposes to take or has taken with respect thereto.

(i) the Company will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, create, incur, issue, assume, Guarantee or otherwise become directly or indirectly liable, contingently or otherwise, with respect to (collectively, “incur”) any Indebtedness (including Acquired Debt);

(ii) the Company will not, and will not permit any of its Restricted Subsidiaries to, issue any Disqualified Stock (including Acquired Disqualified Stock);

(iii) and the Company will not permit any of its Restricted Subsidiaries that are not Subsidiary Guarantors to issue any shares of Preferred Stock (including Acquired Preferred Stock);

provided, however, that the Company and the Subsidiary Guarantors may incur Indebtedness (including Acquired Debt) and the Company and the Subsidiary Guarantors may issue shares of Disqualified Stock (including Acquired Disqualified Stock) if the Fixed Charge Coverage Ratio for the Company’s most recently ended four full fiscal quarters for which earnings have been publicly disclosed immediately preceding the date on which such additional Indebtedness is incurred or such Disqualified Stock is issued would have been at least 2.0 to 1, determined on a pro forma basis (including a pro forma application of the net proceeds therefrom), as if the additional Indebtedness had been incurred or the Disqualified Stock had been issued, as the case may be, at the beginning of such four-quarter period. Letters of credit and bankers’ acceptances shall be deemed to have an aggregate principal amount of Indebtedness equal to the maximum amount available thereunder.

(i) the incurrence by the Company of Indebtedness pursuant to the Existing Credit Facility (and by its Subsidiaries of Guarantees thereof) in an aggregate principal amount at any time outstanding not to exceed an amount equal to the greater of (i) $3.6 billion and (ii) 38.0% of Consolidated Net Tangible Assets of the Company determined as of the date of the incurrence of such Indebtedness after giving pro forma effect to such incurrence and the application of the proceeds therefrom;

(ii) the incurrence by the Company and the Subsidiary Guarantors of Indebtedness represented by the Notes (other than Additional Notes) and the Subsidiary Guarantees thereof;

(iii) the incurrence by the Company and its Restricted Subsidiaries of Existing Indebtedness (other than Indebtedness of the type described in clause (i), (ii) or (iv) through (xii) of this covenant);

(iv) the incurrence by the Company or any of its Restricted Subsidiaries of any Permitted Refinancing in exchange for, or the net proceeds of which are used to extend, refinance, renew, replace, defease or refund, Indebtedness that was permitted to be incurred under the Fixed Charge Coverage Ratio test set forth above or clause (ii) or (iii) above or (xiii) below or this clause (iv);

(v) the incurrence by the Company or any of its Restricted Subsidiaries of intercompany Indebtedness between or among the Company and any of its Restricted Subsidiaries; provided, however, that (i) if the Company or any Subsidiary Guarantor is the obligor on such Indebtedness, such Indebtedness is expressly subordinated to the prior payment in full in cash of all Obligations with respect to the Notes or the Subsidiary Guarantee, as the case may be, and (ii) (A) any subsequent issuance or transfer of Equity Interests that results in any such Indebtedness being held by a Person other than the Company or a Restricted Subsidiary and (B) any sale or other transfer of any such Indebtedness to a Person that is not either the Company or a Restricted Subsidiary shall be deemed, in each case, to constitute an incurrence of such Indebtedness by the Company or such Restricted Subsidiary, as the case may be;

(vi) the incurrence by the Company or any Restricted Subsidiary of Hedging Obligations that are incurred for the purpose of (A) fixing or hedging interest rate or currency risk with respect to any fixed or floating rate Indebtedness that is permitted by the Indenture to be outstanding or any receivable or liability the payment of which is determined by reference to a

foreign currency; provided that the notional principal amount of any such Hedging Obligation does not exceed the principal amount of the Indebtedness to which such Hedging Obligation relates or (B) managing fluctuations in the price or cost of raw materials, manufactured products or related commodities; provided that such obligations are entered into in the ordinary course of business to hedge or mitigate risks to which the Company or any Restricted Subsidiary is exposed in the conduct of its business or the management of its liabilities (as determined by the Company’s or such Restricted Subsidiary’s principal financial officer in the exercise of his or her good faith business judgment);

(vii) the issuance by any of the Company’s Restricted Subsidiaries of shares of Preferred Stock to the Company or a Wholly Owned Restricted Subsidiary of the Company; provided that (A) any subsequent issuance or transfer of Equity Interests that results in such Preferred Stock being held by a Person other than the Company or a Wholly Owned Restricted Subsidiary of the Company or (B) the transfer or other disposition by the Company or a Wholly Owned Restricted Subsidiary of the Company of any such shares to a Person other than the Company or a Wholly Owned Restricted Subsidiary of the Company shall be deemed, in each case, to constitute an issuance of such Preferred Stock by such Subsidiary on such date that is not permitted by this clause (vii);

(viii) the incurrence by the Company or any of its Restricted Subsidiaries of Indebtedness represented by tender, bid, performance, government contract, surety or appeal bonds, standby letters of credit and warranty and contractual service obligations of like nature, trade letters of credit or documentary letters of credit, in each case to the extent incurred in the ordinary course of business of the Company or such Restricted Subsidiary and the incurrence by the Company of Indebtedness represented by letters of credit incurred in connection with the PBGC Settlement;

(ix) the incurrence by the Company or any Restricted Subsidiary of Indebtedness or the issuance by any Restricted Subsidiary of Preferred Stock in an aggregate principal amount (or accreted value or liquidation preference, as applicable) at any time outstanding and incurred or issued in reliance on this clause (ix) not to exceed the greater of (i) $200.0 million and (ii) 2.0% of Consolidated Net Tangible Assets of the Company at the date of such incurrence or issuance, as the case may be;

(x) the issuance by any Finance Subsidiary of Preferred Stock with an aggregate liquidation preference not exceeding the amount of Indebtedness of the Company held by such Finance Subsidiary; provided that the Fixed Charge Coverage Ratio for the Company’s most recently ended four full fiscal quarters for which earnings have been publicly disclosed immediately preceding the date on which such Preferred Stock is issued would have been at least 2.0 to 1, determined on a pro forma basis (including a pro forma application of the net proceeds therefrom) as if such Preferred Stock had been issued at the beginning of such four-quarter period;

(xi) the incurrence of Indebtedness or issuance of Preferred Stock by Foreign Subsidiaries in an aggregate principal amount (or accreted value or liquidation preference, as applicable) at any time outstanding and incurred in reliance upon this clause (xi) not to exceed $200.0 million;

(xii) the Guarantee by any Restricted Subsidiary of Indebtedness of the Company or a Restricted Subsidiary that was permitted to be incurred by another provision of this covenant;

(xiii) the incurrence or issuance, as the case may be, by the Company or any Restricted Subsidiary of Acquired Debt, Acquired Preferred Stock or Acquired Disqualified Stock (including, without limitation, Indebtedness, Disqualified Stock or Preferred Stock of Equistar or Millennium or any Subsidiary thereof existing at the time such Person first becomes a Restricted Subsidiary); provided that immediately after giving effect to such incurrence, the Fixed Charge Coverage Ratio for the Company’s most recently ended four full fiscal quarters for which earnings

have been publicly disclosed immediately preceding the date of such incurrence, determined on a pro forma basis (including a pro forma application of the net proceeds therefrom) as if such Acquired Debt, Acquired Preferred Stock or Acquired Disqualified Stock had been issued at the beginning of such four-quarter period, would be (i) at least 2.0 to 1 or (ii) in the case of Equistar or Millennium or any Subsidiary thereof (or any Restricted Subsidiary into which any of such Persons is merged, consolidated or liquidated), (x) at least 2.0 to 1 or (y) equal to or greater than it would have been immediately preceding such incurrence;

(xiv) with respect to Equistar or Millennium or any Subsidiary thereof (or any Restricted Subsidiary into which any of such Persons is merged, consolidated or liquidated), the incurrence by such Person of Indebtedness under any revolving credit facility in an aggregate principal amount at any time outstanding not to exceed the aggregate principal amount of committed financing under all revolving credit facilities of such Person as in effect on the Issue Date (or, in the case of Equistar, an amount equal to the Permitted Equistar Revolving Credit Amount as of such date); provided that the amount that may be incurred under this clause (xiv) by Equistar and Millennium or any Subsidiary thereof, in the aggregate, may be increased by an amount not to exceed $200.0 million; and

(xv) the incurrence by the Company or any Restricted Subsidiary of Indebtedness represented by Capital Lease Obligations, mortgage financings or purchase money obligations, in each case incurred for the purpose of financing all or any part of the purchase price or cost of design, construction, installation or improvement of property, plant or equipment used in the business of the Company or any Restricted Subsidiary, in an aggregate principal amount, including all Permitted Refinancings incurred to refinance, renew, replace, defease or refund any Indebtedness incurred pursuant to this clause (xv), not to exceed $100.0 million at any time outstanding.

(c) For purposes of determining compliance with this covenant, in the event that an item of Indebtedness or Preferred Stock meets the criteria of more than one of the categories of permitted Indebtedness described in clauses (i) through (xv) above or is entitled to be incurred pursuant to Section 4.06(a), the Company shall, in its sole discretion, classify such item of Indebtedness or Preferred Stock in any manner that complies with this covenant and such Indebtedness or Preferred Stock will be treated as having been incurred pursuant to the clauses or Section 4.06(a), as the case may be, designated by the Company. The amount of Indebtedness issued at a price which is less than the principal amount thereof shall be equal to the amount of the liability in respect thereof determined in accordance with GAAP.

(d) Accrual of interest, accretion or amortization of original issue discount, the payment of interest on any Indebtedness in the form of additional Indebtedness with the same terms, the accumulation of dividends on Disqualified Stock or Preferred Stock (to the extent not paid), and the payment of dividends on Disqualified Stock or Preferred Stock in the form of additional shares of the same class of Disqualified Stock or Preferred Stock will not be deemed to be an incurrence of Indebtedness or an issuance of Disqualified Stock or Preferred Stock for purposes of this Section 4.06.

(e) For purposes of determining compliance with any U.S. dollar-denominated restriction on the incurrence of Indebtedness, the U.S. Dollar-Equivalent principal amount of Indebtedness denominated in a foreign currency shall be calculated based on the relevant currency exchange rate in effect on the date such Indebtedness was incurred, in the case of term Indebtedness, or first committed, in the case of revolving credit Indebtedness; provided, however, that if such Indebtedness is incurred to refinance other Indebtedness denominated in a foreign currency, and such refinancing would cause the applicable U.S. dollar-denominated restriction to be exceeded if calculated at the relevant currency exchange rate in effect on the date of such refinancing, such U.S. dollar-denominated restriction shall be deemed not to have been exceeded so long as the principal amount of such refinancing Indebtedness (including any additional Indebtedness incurred to pay interest or premiums required by the instruments governing such Indebtedness being refinanced and fees and other transactional expenses incurred in connection therewith) does not exceed the principal amount of such Indebtedness being refinanced.

Notwithstanding any other provision of this covenant, the maximum amount of Indebtedness that the Company or any Restricted Subsidiary may incur pursuant to this covenant shall not be deemed to be exceeded solely as a result of fluctuations in the exchange rates of currencies. The principal amount of any Indebtedness incurred to refinance other Indebtedness, if incurred in a different currency from the Indebtedness being refinanced, shall be calculated based on the currency exchange rate applicable to the currencies in which such refinancing Indebtedness is denominated that is in effect on the date of such refinancing.

Section 4.07. Limitation on Restricted Payments. (a) The Company will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly:

(i) declare or pay any dividend or make any distribution on account of the Company’s or any of its Restricted Subsidiaries’ Equity Interests (other than (x) dividends or distributions payable in Qualified Equity Interests of the Company and (y) dividends or distributions payable to the Company or any Restricted Subsidiary of the Company);

(ii) purchase, redeem or otherwise acquire or retire for value any Equity Interests of the Company, any of its Restricted Subsidiaries or any Affiliate of the Company (other than any such Equity Interests owned by the Company or any of its Restricted Subsidiaries), excluding any such purchase, redemption or other acquisition that constitutes a Permitted Investment;

(iii) make any principal payment on, or purchase, redeem, defease or otherwise acquire or retire for value, prior to the Stated Maturity thereof, any Indebtedness (“Subordinated Debt”) of the Company or any Restricted Subsidiary that is subordinated by its terms to the Notes or the Subsidiary Guarantees, as applicable (other than Indebtedness owed to the Company or any Restricted Subsidiary), excluding the purchase, redemption, defeasance or other acquisition or retirement of Subordinated Debt purchased in anticipation of satisfying a sinking fund obligation, principal installment or final maturity, in each case due within one year of the date of purchase, redemption, defeasance or other acquisition or retirement; or

(iv) make any Restricted Investment (all such payments and other actions set forth in clauses (i) through (iv) above being collectively referred to as “Restricted Payments”);

unless, at the time of and after giving effect to such Restricted Payment (the amount of any such Restricted Payment, if other than cash, shall be the fair market value (as conclusively evidenced by a Board Resolution) of the asset(s) proposed to be transferred by the Company or such Restricted Subsidiary, as the case may be, pursuant to such Restricted Payment):

(A) no Default or Event of Default shall have occurred and be continuing after giving effect thereto;

(B) the Company would, at the time of such Restricted Payment and after giving pro forma effect thereto as if such Restricted Payment had been made at the beginning of the most recently ended four full fiscal quarters for which earnings have been publicly disclosed immediately preceding the date of such Restricted Payment, have been permitted to incur at least $1.00 of additional Indebtedness pursuant to the Fixed Charge Coverage Ratio test set forth in Section 4.06(a); and

(C) such Restricted Payment, together with the aggregate of all other Restricted Payments made by the Company and its Restricted Subsidiaries on or after the Issue Date (excluding Restricted Payments permitted by Section 4.07(b)(ii) (to the extent paid to the Company or any of its Restricted Subsidiaries or to the extent such distributions are deducted as a minority interest in calculating Consolidated Net Income), Section 4.07(b)(iii), Section 4.07(b)(iv), Section 4.07(b)(v), Section 4.07(b)(ix), Section 4.07(b)(xiii), Section 4.07(b)(xv) and Section 4.07(b)(xvi), and 50% of any Restricted Payments permitted by Section 4.07(b)(vii)) is less than or equal to the sum, without duplication, of:

(i) 50% of the Consolidated Net Income of the Company for the period (taken as one accounting period) beginning on July 1, 2006 to the end of the Company’s most recently ended fiscal quarter for which earnings have been publicly disclosed at the time of such Restricted Payment (or, if such Consolidated Net Income for such period is a deficit, less 100% of such deficit), plus

(ii) 100% of the aggregate net cash proceeds, or the fair market value of property other than cash (including Capital Stock of Persons engaged in a Permitted Business or property used or useful in a Permitted Business), received by the Company or any of its Restricted Subsidiaries from the issue or sale (other than to a Subsidiary or Joint Venture of the Company) after the Issue Date of Qualified Equity Interests of the Company or of debt securities or Disqualified Stock of the Company or any of its Restricted Subsidiaries that have been converted into or exchanged for such Qualified Equity Interests of the Company, plus

(iii) the amount (to the extent not included in calculating Consolidated Net Income) equal to (A) the net reduction in Restricted Investments (other than a Restricted Investment permitted to be made pursuant to Sections 4.07(b)(vii) or 4.09(b)(x)) that was made after the Issue Date resulting from repurchases, repayments, liquidations, redemptions or reductions of such Restricted Investments by such Person, (B) proceeds realized on the sale of such Restricted Investments (to the extent not included in item (j) of the definition of “Permitted Investments”), dividends, distributions and proceeds representing the return of capital with respect to such Restricted Investments, less the cost of disposition, if any, and (C) the release of any Guarantee that had been a Restricted Payment made under this Section 4.09(a) (except to the extent any amounts are paid under such Guarantee), plus

(iv) the amount by which Indebtedness of the Company or its Restricted Subsidiaries is reduced on the Company’s balance sheet upon the conversion or exchange (other than by a Subsidiary of the Company) subsequent to the Issue Date of any Indebtedness of the Company or its Restricted Subsidiaries convertible into or exchangeable for Qualified Equity Interests of the Company (less the amount of cash, or the fair market value of any other property, distributed by the Company upon such conversion or exchange), plus

(v) in the event the Company or any Restricted Subsidiary makes any Investment in a Person that, as a result of or in connection with such Investment, becomes a Restricted Subsidiary or is merged or consolidated with the Company or a Restricted Subsidiary, an amount equal to the Company’s or any Restricted Subsidiary’s Investment in such Person prior to the time it became a Restricted Subsidiary or the time of such merger or consolidation, up to the amount of such Investment previously made before such time and after the Issue Date by the Company or any Restricted Subsidiary in such Person as a Restricted Investment pursuant to this Section 4.09(a), plus

(vi) an amount equal to the sum of (A) (x) the net reduction in Investments in Unrestricted Subsidiaries resulting from repurchases, repayments, liquidations, redemptions or reductions of such Restricted Investments by such person and (y) proceeds realized on the sale of such Restricted Investments, dividends, distributions and proceeds representing the return of capital with respect to such Restricted Investments (to the extent not included in calculating Consolidated Net Income), in each case to the Company or any Restricted Subsidiary from Unrestricted Subsidiaries and (B) the portion (proportionate to the Company’s equity interest in such Subsidiary) of the fair market value of the net assets of an Unrestricted Subsidiary at the time such Unrestricted Subsidiary is designated a Restricted Subsidiary; provided, however, that the foregoing sum shall not exceed, in the case of any Unrestricted Subsidiary, the amount of Restricted Investments (other than Restricted Investments permitted to be made pursuant to Sections 4.07(b)(vii) or 4.07(b)(x) below) previously made after the Issue Date by the Company or any Restricted Subsidiary in such Unrestricted Subsidiary and, to the extent necessary to avoid duplication, shall exclude Investments outstanding under clause (j) of the definition of “Permitted Investments”.

(b) If, other than with respect to payments made under Section 4.07(b)(i) and Section 4.07(b)(xiii) below, no Default or Event of Default shall have occurred and be continuing after giving effect to such Restricted Payment, the foregoing provisions will not prohibit the following Restricted Payments:

(i) the payment of any dividend or the consummation of any irrevocable redemption within 60 days after the date of declaration of the dividend or giving of the redemption notice, as the case may be, if at said date of declaration or notice such payment would have complied with the provisions of the Indenture;

(ii) dividends or distributions by any Restricted Subsidiary of the Company payable (x) to all holders of a class of Capital Stock of such Restricted Subsidiary on a pro rata basis or on a basis that is more favorable to the Company, or (y) to all holders of a class of Preferred Stock of a Restricted Subsidiary that is not a Subsidiary Guarantor issued after the Issue Date in compliance with Section 4.06;

(v) the defeasance, redemption or repurchase of Subordinated Debt with the net cash proceeds from an incurrence of Permitted Refinancing or in exchange for Qualified Equity Interests of the Company, or out of the net cash proceeds from the sale (other than to a Subsidiary or Joint Venture of the Company) of Qualified Equity Interests of the Company (so long as such redemption, repurchase, retirement or other acquisition occurs within 90 days after such sale); provided that the amount of any such net cash proceeds that are utilized for any such redemption, repurchase, retirement or other acquisition shall be excluded from clause (C)(ii) of Section 4.07(a);

(vi) the repurchase, redemption or other acquisition or retirement for value of (x) any Equity Interests of the Company or any Subsidiary of the Company held by any member of the Company’s (or any of its Subsidiaries’) management pursuant to any management equity subscription agreement or stock option agreement or (y) any Equity Interests of the Company that are or are intended to be used to satisfy issuances of Equity Interests upon exercise of employee or director stock options or upon exercise or satisfaction of other similar instruments outstanding under employee or director benefit plans of the Company or any Subsidiary of the Company; provided that the aggregate price paid for all such repurchased, redeemed, acquired or retired Equity Interests shall not exceed $25.0 million in any fiscal year of the Company;

(vii) Restricted Investments in any Joint Venture made during any fiscal year of the Company or within 45 days after the end of such fiscal year in amounts that, together with all other Restricted Investments made in such Joint Venture in respect of such fiscal year in reliance on this clause (vii) during such fiscal year or within 45 days after the end of such fiscal year, do not exceed the amount of dividends or distributions previously paid in respect of such fiscal year to the Company or any Restricted Subsidiary by such Joint Venture;

(viii) the payment of dividends on the Company’s common stock at a rate not to exceed $0.90 per share per annum (such $0.90 amount to be appropriately adjusted to reflect any stock split, reverse stock split, stock dividend or similar transactions made after the Issue Date so

that the aggregate amount of dividends payable after such transaction is the same as the amount payable immediately before such transaction);

(x) Investments in any Joint Venture or Unrestricted Subsidiary organized to construct, own and/or operate one or more plants engaged in a Permitted Business in an aggregate amount that, together with all other Investments made pursuant to this Section 4.07(b)(x), does not exceed $100.0 million at any time outstanding (after giving effect to any net reduction or proceeds realized on any Investments made pursuant to this Section 4.07(b)(x), as set forth in Section 4.07(a)(iii), in an amount not to exceed the amount of such Investments previously made pursuant to this Section 4.07(b)(x);

(xi) (A) the transfer of the TDI Assets to a newly formed Joint Venture or Unrestricted Subsidiary or (B) the designation of any Restricted Subsidiary that has no assets or liabilities other than all or a portion of the TDI Assets as an Unrestricted Subsidiary, in each case, in connection with the incurrence of Indebtedness by such Joint Venture or Unrestricted Subsidiary or Rhodia or a wholly-owned subsidiary of Rhodia to improve the Rhodia TDI Plant;

(xii) the repurchase of any Subordinated Debt at a purchase price not greater than 101% of the principal amount thereof in the event of (x) a Change of Control pursuant to a provision no more favorable to the holders thereof than the provisions of Section 4.14 or (y) an Asset Sale pursuant to a provision no more favorable to the holders thereof than the provisions of Section 4.09; provided that, in each case, before such repurchase, the Company has made a Change of Control Offer or Asset Sale Offer, as applicable, and repurchased all Notes that were validly tendered for payment in connection with such Change of Control Offer or Asset Sale Offer;

(xiii) distributions by any Restricted Subsidiary or Joint Venture of chemicals to a holder of Capital Stock of such Restricted Subsidiary or Joint Venture if such distributions are made pursuant to a provision in a joint venture agreement or other arrangement entered into in connection with the establishment of such Joint Venture or Restricted Subsidiary that requires such holder to pay a price for such chemicals equal to that which would be paid in a comparable transaction negotiated on an arm’s-length basis (or pursuant to a provision that imposes a substantially equivalent requirement);

(xiv) any other Restricted Payment that, together with all other Restricted Payments made pursuant to this Section 4.07(b)(xiv) on or after the Issue Date, does not exceed $200 million at any time outstanding (after giving effect to any dividends, return of capital and subsequent reduction in the amount of any Investments made pursuant to this Section 4.07(b)(xiv) as a result of the repayment or other disposition thereof, as set forth in clause (C)(iii) of Section 4.07(a), in an amount not to exceed the amount of such Investments previously made pursuant to this Section 4.07(b)(xiv);

(xv) dividends or distributions by any Joint Venture (other than Equistar) to all holders of a class of Capital Stock of such Joint Venture permitted by Section 4.07(b)(ii)(x) above; provided that after giving effect to such dividends or distributions and any related transactions, the Joint Venture making such dividends or distributions to such holders is contractually entitled to receive, and receives within 180 days before or after the date of such dividends or distributions, directly or indirectly, an equivalent or larger cash payment from each such holder (other than from a holder that is the Company or any Restricted Subsidiary) or from an Affiliate of such holder, which cash payment has not been previously applied pursuant to this Section 4.07(b)(xv) to offset any other dividend or distribution by such Joint Venture to such holder and (y) such dividends or distributions do not exceed such holders’ pro rata share of the Joint Venture’s cash flows from operating activities, minus any non-cash charge to the extent that it represents an accrual of or

reserve for cash expenditures in any future period or amortization of a prepaid cash expense in any future period; and

(xvi) Restricted Payments of the type described in Section 4.07(a)(ii) and Section 4.07(a)(iii) in an aggregate amount not to exceed $500 million; provided that after giving pro forma effect thereto as if such Restricted Payment had been made at the beginning of the most recently ended four-full-fiscal-quarter period for which earnings have been publicly disclosed immediately preceding the date of such Restricted Payment, the Company’s Consolidated Leverage Ratio would have been less than 2.5 to 1.0.

(c) The Board of Directors may designate any Restricted Subsidiary to be an Unrestricted Subsidiary if such designation would not cause a Default. For purposes of making such determination, all outstanding Investments by the Company and its Restricted Subsidiaries in the Subsidiary so designated will be deemed to be Restricted Payments at the time of such designation and will reduce the amount available for Restricted Payments under Section 4.07(a) (except to the extent such Investments were repaid in cash, and, in the case of a Joint Venture (and any Subsidiary of a Joint Venture) designated as an Unrestricted Subsidiary on the first day that it is a Subsidiary of the Company, except to the extent that such Investments were made after the Issue Date). All such outstanding Investments (except as provided in the parenthetical included in the preceding sentence) will be deemed to constitute Investments in an amount equal to the fair market value of such Investments at the time of such designation (as conclusively determined by the Board of Directors). Such designation will only be permitted if any such Restricted Payment would be permitted at such time and if such Restricted Subsidiary otherwise meets the definition of an Unrestricted Subsidiary. In the case of any designation by the Company of a Person as an Unrestricted Subsidiary on the first day that such Person is a Subsidiary of the Company in accordance with the provisions of the Indenture, such designation shall be deemed to have occurred for all purposes of the Indenture simultaneously with, and automatically upon, such Person becoming a Subsidiary.

Section 4.08. Limitation on Dividend and other Payment Restrictions Affecting Restricted Subsidiaries and Joint Ventures. (a) 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 restriction on the ability of any Restricted Subsidiary to:

(i) (A) pay dividends or make any other distributions to the Company or any of its Restricted Subsidiaries (1) on its Capital Stock, or (2) with respect to any other interest or participation in, or measured by, its profits, or (B) pay any Indebtedness owed to the Company or any of its Restricted Subsidiaries;

(ii) make loans or advances to the Company or any of its Restricted Subsidiaries; or

(iii) transfer any of its properties or assets to the Company or any of its Restricted Subsidiaries;

(a) existing agreements as in effect on the Issue Date and as amended, modified, extended, renewed, refunded, refinanced, restated or replaced from time to time; provided that any such agreement and related documentation as so amended, modified, extended, renewed, refunded, refinanced, restated or replaced is not materially more restrictive, taken as a whole, as to the matters enumerated above than such agreement and related documentation as in effect on the Issue Date (as conclusively evidenced by a resolution of the Board of Directors);

(b) Indebtedness permitted by this Indenture to be incurred containing restrictions on the ability of Restricted Subsidiaries to consummate transactions of the types described in clause (i), (ii) or (iii) above not materially more restrictive, taken as a whole, than those contained in this Indenture and the Existing Credit Facility;

(e) restrictions with respect to a Person or assets acquired by the Company or any of its Restricted Subsidiaries existing at the time of such acquisition, including through merger, consolidation, amalgamation or liquidation, (except to the extent such restrictions were put in place in connection with or in contemplation of such acquisition), which restrictions are not applicable to any Person, or the properties or assets of any Person, other than the Person, or the property or assets of the Person, or the assets, so acquired, and as amended, modified, extended, renewed, refunded, refinanced, restated or replaced from time to time; provided that any such restriction as so amended, modified, extended, renewed, refunded, refinanced, restated or replaced is not materially more restrictive, taken as a whole, as to the matters enunciated above than such restrictions existing at the time of such acquisition;

(f) customary, provisions in leases, licenses and other agreements entered into in the ordinary course of business restricting the subletting, assignment or transfer of any property that is subject to such lease, license or agreement or the assignment of any such agreement;

(g) construction loans and purchase money obligations (including Capital Lease Obligations) for property acquired in the ordinary course of business that impose restrictions of the nature described in clause (iii) above on the property so constructed or acquired;

(h) in the case of clause (iii) above, restrictions regarding Liens on property of a Restricted Subsidiary to the extent such restrictions restrict the transfer of the property subject to such Liens;

(i) a Permitted Refinancing, provided that the restrictions contained in the agreements governing such Permitted Refinancing are not materially more restrictive, taken as a whole, than those contained in the agreements governing the Indebtedness being refinanced (as conclusively evidenced by a Board Resolution);

(j) customary restrictions on a Finance Subsidiary imposed in such Finance Subsidiary’s organizational documents or by the terms of its Preferred Stock;

(k) any restriction with respect to shares of Capital Stock of a Restricted Subsidiary imposed pursuant to an agreement entered into for the sale or disposition of such shares of Capital Stock or any restriction with respect to the assets of a Restricted Subsidiary imposed pursuant to an agreement entered into for the sale or disposition of such assets or all or substantially all the Capital Stock of such Restricted Subsidiary pending the closing of such sale or disposition;

(1) in the case of any Restricted Subsidiary that is a Joint Venture, customary restrictions on such Restricted Subsidiary contained in its joint venture agreement, which restrictions arc consistent with the past practice of the Company and its Restricted Subsidiaries (as conclusively evidenced by a Board Resolution);

(m) restrictions with respect to Equistar or Millennium or the property or assets thereof or a Subsidiary of Equistar or Millennium or the property or assets thereof, in each case, existing at the time Equistar or Millennium or any Subsidiary of Equistar or Millennium first becomes a Restricted Subsidiary or at the time such assets are acquired by the Company or any Restricted Subsidiary (except to the extent such restrictions were

put in place in connection with or in contemplation of Equistar’s or Millennium’s or such Subsidiary’s becoming a Restricted Subsidiary or such asset acquisition), which restrictions are not applicable to any Person, or the properties or assets of any Person, other than Equistar or Millennium or the property or assets thereof or a Subsidiary of Equistar or Millennium or the property or assets thereof together with restrictions with respect to such Person or assets not materially more restrictive, taken as a whole, than such existing restrictions existing by reason of any Indebtedness incurred by such Persons after the Issue Date in compliance with the Indenture, and as amended, modified, extended, renewed, refunded, refinanced, restated or replaced from time to time; provided that any such restrictions as so amended, modified, extended, renewed, refunded, refinanced, restated or replaced are not materially more restrictive, taken as a whole, as to the matters enunciated above than such existing restrictions;

(n) the Existing Credit Facility and related documentation as the same is in effect on the Issue Date and as amended, modified, extended, renewed, refunded, refinanced, restated or replaced from time to time; provided that the Existing Credit Facility and related documentation as so amended, modified, extended, reviewed, refunded, refinanced, restated or replaced is not materially more restrictive, taken as a whole, as to the matters enumerated above than the Existing Credit Facility and related documentation as in effect on the Issue Date (as conclusively evidenced by a Board Resolution); and

(o) any such restrictions under an agreement governing Indebtedness of a Foreign Subsidiary permitted under Section 4.06.

For purposes of determining compliance with this covenant, in the event that a restriction meets the criteria of more than one of the categories of permitted restrictions described in clauses (a) through (o) above, the Company shall, in its sole discretion, classify such restriction in any manner that complies with this covenant, and such restriction will be treated as existing pursuant to the clauses designated by the Company. For purposes of this covenant, (x) the priority of any Preferred Stock in receiving dividends or liquidating distributions prior to dividends or liquidating distributions being paid on common stock and (y) the subordination of (including the application of any standstill requirements to) loans or advances made to the Company or any Restricted Subsidiary to other Indebtedness incurred by the Company or any Restricted Subsidiary, shall not be deemed to constitute such an encumbrance or restriction.

(b) The Company will use best efforts (consistent with its contractual obligations and fiduciary duties to any Joint Venture, in each case, as in effect on the Issue Date) not to permit any of its Joint Ventures that are not Restricted Subsidiaries to, directly or indirectly, create or otherwise cause or suffer to exist or become effective any consensual restriction on the ability of such Joint Venture to:

(i) (A) pay dividends or make any other distributions to the Company or any of its Restricted Subsidiaries (1) on its Capital Stock or (2) with respect to any other interest or participation in, or measured by, its profits or (B) pay any Indebtedness owed to the Company or any of its Restricted Subsidiaries;

(ii) make loans or advances to the Company or any of its Restricted Subsidiaries; or

(iii) transfer any of its properties or assets to the Company or any of its Restricted Subsidiaries;

(a) such Joint Venture’s joint venture agreement or its credit facility (provided that in each case such restrictions are consistent with the past practice of the Company);

(b) in the case of any Joint Venture existing on the Issue Date, its existing agreements as in effect on the date of the Indenture and as amended, modified, extended, restated or replaced from time to time; provided that no such amendment, modification, extension, restatement or replacement results in agreements that are materially more restrictive, taken as a whole, as to the matters enumerated above than the existing agreements as in effect on the date of the Indenture (as conclusively evidenced by a Board Resolution); and

(c) the restrictions described in clauses (d), (e), (f), (g), (h), (j), (k) and (n) of Section 4.08(a) (assuming that references in clauses (h) and (k) to a Restricted Subsidiary were references to a Joint Venture).

Section 4.09. Limitation on Sales of Assets. (a) The Company will not, and will not permit any of its Restricted Subsidiaries to, consummate an Asset Sale unless:

(i) the Company and/or the Restricted Subsidiary, as the case may be, receives consideration in respect of such Asset Sale at least equal to the fair market value (as determined as of the date of contractually agreeing to such Asset Sale and as conclusively determined in good faith by the senior management of the Company (and which in the case of an Asset Sale with a fair market value in excess of $100.0 million shall be conclusively evidenced by a resolution of the Board of Directors set forth in an Officer’s Certificate delivered to the Trustee)) of the assets or Equity Interests issued or sold or otherwise disposed of; and

(A) at least 75% of the consideration received in the Asset Sale by the Company and/or such Restricted Subsidiary is in the form of (I) cash or Cash Equivalents or (II) a controlling interest or a joint venture interest (to the extent otherwise permitted by the Indenture) in a business engaged in a Permitted Business or long-term property or assets that are used or useful in a Permitted Business (“Permitted Consideration”); or

(B) after giving effect to such Asset Sale, the aggregate fair market values of all forms of consideration other than Permitted Consideration received for all Asset Sales since the Issue Date does not exceed in the aggregate $100.0 million. For purposes of this Section 4.09(a)(ii)(B), the fair market value of the consideration other than Permitted Consideration received in connection with each Asset Sale shall be determined as of the date of contractually agreeing to such Asset Sale.

For purposes of this provision, each of the following will be deemed to be cash: (w) the amount of any liabilities (as shown on the Company’s or such Restricted Subsidiary’s most recent balance sheet) of the Company or any Restricted Subsidiary (other than contingent liabilities and liabilities that are by their terms subordinated to the Notes or any guarantee thereof) that are assumed by the transferee of any such assets pursuant to a customary novation agreement that releases the Company or such Restricted Subsidiary from further liability, (x) the amount of any securities, notes or other obligations received by the Company or any such Restricted Subsidiary from such transferee that are converted within 180 days by the Company or such Restricted Subsidiary into cash or Cash Equivalents (to the extent of the cash or Cash Equivalents received), (y) the amount of any accounts receivable of a business retained by the Company or any Restricted Subsidiary, as the case may be, following the sale of such business (other than such accounts receivable that (i) are past due more than 90 days or (ii) have a payment date greater than 120 days from the date of invoice creating such accounts receivable) and (z) the amount of any Indebtedness of any Restricted Subsidiary that is no longer a Restricted Subsidiary as a result of such Asset Sale, if the Company and its Restricted Subsidiaries are immediately released from all

Guarantees, if applicable, of payment or other obligations with respect to such Indebtedness and such Indebtedness is no longer a liability of the Company or any of its Restricted Subsidiaries.

Notwithstanding the foregoing, the 75% limitation referred to above shall be deemed satisfied with respect to any Asset Sale in which the cash or Cash Equivalents portion of the consideration received therefrom, determined in accordance with the foregoing provision on an after-tax basis, is equal to or greater than what the after-tax cash or Cash Equivalent proceeds would have been had such Asset Sale complied with the aforementioned 75% limitation.

(b) Within 360 days after the receipt of any Net Proceeds from an Asset Sale, the Company may apply such Net Proceeds, at its option:

(i) to (A) repay Indebtedness under the Existing Credit Facility, and any secured Indebtedness (and to correspondingly reduce commitments with respect thereto in the case of revolving borrowings) of the Company or a Subsidiary Guarantor, (B) repay Indebtedness incurred to acquire assets if such Indebtedness is repaid with the proceeds from an Asset Sale of any such assets, provided such Asset Sale is within 180 days of the incurrence of such Indebtedness or (C) repay Indebtedness (and to correspondingly reduce commitments with respect thereto in the case of revolving borrowings) of any Restricted Subsidiary that is not a Subsidiary Guarantor; or

(ii) to acquire Additional Assets (to the extent otherwise permitted by the Indenture) or to make a capital expenditure, in each case, in a Permitted Business (or enter into a binding commitment for any such acquisition or expenditure); provided that such binding commitment shall be treated as a permitted application of Net Proceeds from the date of such commitment until and only until the earlier of (x) the date on which such expenditure or acquisition is consummated and (y) the 180th day following the expiration of the aforementioned 360-day period. If the acquisition or expenditure contemplated by such binding commitment is not consummated on or before such 180th day and the Company shall not have applied such Net Proceeds pursuant to clause (i) above on or before such 180th day, such commitment shall be deemed not to have been a permitted application of Net Proceeds at any time.

Pending the final application of any such Net Proceeds, the Company or any Restricted Subsidiary may temporarily reduce the revolving Indebtedness under the Existing Credit Facility or otherwise invest such Net Proceeds in any manner that is not prohibited by the Indenture. Any Net Proceeds from Asset Sales that are not applied or invested as provided in the first sentence of this Section 4.09(b) will be deemed to constitute “Excess Proceeds.”

(c) If on the 361st day after an Asset Sale (or, at the Company’s option, any earlier date), the aggregate amount of Excess Proceeds under the Indenture exceeds $75.0 million, the Company will be required to make an offer to all Holders of Notes (an “Asset Sale Offer”) to purchase the maximum principal amount of Notes and, (x) if the Company is required to do so under the terms of any other Indebtedness ranking pari passu with such Notes, such other Indebtedness, and (y) if the Company elects to do so, any Existing ARCO Chemical Debt, on a pro rata basis with the Notes, that may be purchased out of the Excess Proceeds, at an offer price in cash in an amount equal to 100% of the principal amount thereof plus accrued and unpaid interest thereon to the date of purchase, in accordance with the procedures set forth herein.

To the extent that the aggregate amount of Notes (and any other pari passu Indebtedness subject to such Asset Sale Offer) tendered pursuant to such Asset Sale Offer is less than the Excess Proceeds, the Company may, subject to the other terms of the Indenture, use any remaining Excess Proceeds for any purpose not prohibited by this Indenture.

If the aggregate principal amount of Notes surrendered by Holders thereof in connection with an Asset Sale Offer exceeds the amount of Excess Proceeds, the Trustee shall select the Notes to be purchased on a pro rata basis.

Upon completion of the offer to purchase made under the Indenture, the amount of Excess Proceeds shall be reset at zero.

(d) The Company will comply with the requirements of Rule l4e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent such laws and regulations are applicable in connection with any Asset Sale Offer.

Section 4.10. Limitation on Affiliate Transactions. (a) The Company will not, and will not permit any of its Restricted Subsidiaries to, sell, lease, transfer or otherwise dispose of any of its properties or assets to, or purchase any property or assets from, or enter into or make any contract, agreement, understanding, loan, advance or Guarantee with, or for the benefit of, any Affiliate of the Company (each of the foregoing, an “Affiliate Transaction”), unless:

(i) such Affiliate Transaction is on a basis no less favorable to the Company and its Restricted Subsidiaries than could be obtained in a comparable transaction on an arm’s-length basis with a Person who is not an Affiliate of the Company, or, if no such comparable transaction with a Person who is not an Affiliate of the Company is available, on terms that are fair from a financial point of view to the Company or such Restricted Subsidiary; and

(ii) the Company delivers to the Trustee (A) with respect to any Affiliate Transaction involving aggregate net consideration in excess of $25 million, a Board Resolution set forth in an Officer’s Certificate certifying that such Affiliate Transaction complies with clause (i) above and that such Affiliate Transaction has been approved by a majority of the members of the Board of Directors and (B) with respect to any Affiliate Transaction involving aggregate net consideration in excess of $50 million, a Board Resolution set forth in an Officer’s Certificate certifying that such Affiliate Transaction complies with clause (i) above and that such Affiliate Transaction has been approved by a majority of the disinterested members of the Board of Directors, if any, or if there are no such disinterested members, then the Company shall have received a written opinion from an independent investment banking, accounting or appraisal firm of nationally recognized standing that the terms of such Affiliate Transaction are not materially less favorable to the Company or the applicable Restricted Subsidiary than those that might reasonably have been obtained in a comparable transaction on an arm’s length basis with a Person who is not an Affiliate of the Company or that such terms are fair to the Company or the applicable Restricted Subsidiary from a financial point of view.

(b) Notwithstanding the foregoing, the following shall not be deemed to be Affiliate Transactions and therefore not subject to the requirements of Section 4.10(a):

(i) transactions or payments pursuant to any employment arrangements or employee, officer or director benefit plans or arrangements entered into by the Company or any of its Restricted Subsidiaries in the ordinary course of business;

(ii) transactions between or among the Company and/or its Restricted Subsidiaries;

(iii) any Restricted Payment permitted by Section 4.07 and any Permitted Investment;

(v) transactions entered into between or among the Company or any of its Restricted Subsidiaries and any Joint Venture, or other Affiliate that would otherwise be subject to this covenant solely because the Company or a Restricted Subsidiary owns any Capital Stock of or otherwise controls such Person, on a basis no less favorable to the Company or such Restricted

Subsidiary than could be obtained in a comparable transaction on an arm’s-length basis with a Person who is not an Affiliate of the Company, or, if no such comparable transaction with a Person who is not an Affiliate of the Company is available, on terms that are fair from a financial point of view to the Company or such Restricted Subsidiary;

(viii) transactions effected pursuant to the terms of an agreement that was entered into, alone or as part of a series of agreements, pursuant to or in accordance with this Section 4.10;

(xii) transactions with any customer, client, supplier, distributor or any other purchase or sale of goods or services, in each case in the ordinary course of business and otherwise in compliance with the terms of this Indenture, which when taken together with other transactions with the same Person are, in the reasonable determination of the Board of Directors of the Company or the senior management of the Company, fair to the Company and its Restricted Subsidiaries or are on terms not less favorable than might have been obtained in a comparable transaction at such time on an arm’s length basis from a Person who is not an Affiliate.

Section 4.11. Limitation on Liens. The Company will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, create, incur, assume or suffer to exist any Lien (except Permitted Liens) on any asset now owned or hereafter acquired, or any income or profits therefrom, securing any Indebtedness, unless all payments due under this Indenture and the Notes or the Subsidiary Guarantees are secured on an equal and ratable basis with the Indebtedness so secured (or, if such Indebtedness is subordinated by its terms to the Notes or the Subsidiary Guarantees, prior to the Indebtedness so secured) until such time as such Indebtedness is no longer so secured.

Section 4.13. No Amendment to Subordination Provisions. The Company will not amend, modify or alter the Existing Senior Subordinated Note Indenture in any way that would amend the subordination provisions of the Existing Senior Subordinated Note Indenture or any of the defined terms used therein in a manner that would be adverse to the holders of the Notes.

The Paying Agent will promptly mail to each Holder of Notes so tendered the Change of Control Payment for such Notes, and the Trustee will promptly authenticate and mail (or cause to be transferred by book entry) to each Holder a Note equal in principal amount to any unpurchased portion of the Notes surrendered, if any; provided that each such Note will be in a principal amount of $1,000 or an integral multiple thereof.

(d) The Company will not be required to make a Change of Control Offer upon a Change of Control if a third party makes the Change of Control Offer at the same or a higher purchase price, at the same times and otherwise in substantial compliance with the requirements applicable to a Change of Control Offer made by the Company and purchases all Notes validly tendered and not withdrawn under such Change of Control Offer.

Section 4.15. Limitation on Sale and Leaseback Transactions.

Section 4.16. Limitation on Line of Business. The Company will not, and will not permit any of its Restricted Subsidiaries to, engage in any business other than Permitted Businesses, except to such extent as would not be material to the Company and its Subsidiaries taken as a whole.

the provisions of Sections 4.06, 4.07, 4.08, 4.09, 4.10, 4.16, 4.17 and 4.22 will terminate and cease to have any further effect from and after the first date when the Notes are rated Investment Grade.

Section 4.19. Existence. Subject to Articles 4 and 5 of this Indenture, the Company will do or cause to be done all things necessary to preserve and keep in full force and effect its existence and the existence of each of its Restricted Subsidiaries in accordance with the respective organizational documents of the Company and each such Subsidiary and the rights (whether pursuant to charter, partnership certificate, agreement, statute or otherwise), material licenses and franchises of the Company and each such Subsidiary; provided that the Company shall not be required by this Section 4.19 to preserve any such right, license or franchise, or the existence of any Restricted Subsidiary, if the Company shall determine that the maintenance or preservation thereof is no longer desirable in the conduct of the business of the Company and its Restricted Subsidiaries taken as a whole.

Section 4.20. Payment of Taxes and Other Claims.

The Company will maintain, and will cause each of its Restricted Subsidiaries to maintain (either in the Company’s name or in such Subsidiary’s own name) insurance on all their respective properties consistent with the insurance maintained on the Issue Date or otherwise in at least such amounts (with no materially greater risk retention) and against at least such risks as are usually maintained, retained or insured against in the same general area by companies of established repute owning similar properties in such area and engaged in the same or a similar business, in either case, to the extent available to the Company and its Restricted Subsidiaries on commercially reasonable terms.

Section 4.22. Limitation on Issuance of Guarantees by Restricted Subsidiaries. (a) The Company will not permit any Restricted Subsidiary (other than a Foreign Subsidiary or a Restricted Subsidiary that is already a Subsidiary Guarantor) to Guarantee the payment of any other Indebtedness of the Company or any other Subsidiary Guarantor in excess of a De Minimis Guaranteed Amount, unless such Restricted Subsidiary, within 10 business days of the date of entering into such Guarantee, executes and delivers a supplemental indenture to the Indenture providing for the Guarantee of the payment of the notes issued thereunder by such Restricted Subsidiary. If the Notes are (A) pari passu with the Guaranteed Indebtedness, then the Subsidiary Guarantee shall be pari passu with, or senior to, the guarantee of such Guaranteed Indebtedness or (B) senior to the Guaranteed Indebtedness, then the Subsidiary Guarantee shall be senior to the guarantee of such Guaranteed Indebtedness at least to the extent that the Notes are senior to such Guaranteed Indebtedness.

(b) Notwithstanding the foregoing, the Subsidiary Guarantee of a Subsidiary Guarantor will be released:

(i) in connection with any sale or other disposition of all or substantially all of the assets of such Subsidiary Guarantor (including by way of merger or consolidation) to a Person that is not (either before or after giving effect to such transaction) the Company or a Restricted Subsidiary, if the sale or other disposition complies with the applicable provisions of the Indenture;

(ii) in connection with any sale or other disposition of all of the Capital Stock of such Subsidiary Guarantor to a Person that is not (either before or after giving effect to such transaction) the Company or a Restricted Subsidiary, if the sale or other disposition complies with the applicable provisions of the Indenture;

(iii) if such Subsidiary Guarantor is a Restricted Subsidiary and the Company designates such Subsidiary Guarantor as an Unrestricted Subsidiary in accordance with the applicable provisions of the Indenture;

(v) upon the liquidation or dissolution of such Subsidiary Guarantor provided no Default or Event of Default has occurred or is continuing under the Indenture; or

(vi) at such time as such Subsidiary Guarantor ceases to guarantee Indebtedness of the Company or any other Subsidiary Guarantor (other than guarantees under the Notes) in excess of the De Minimis Guaranteed Amount, except to the extent all such other guarantees were discharged or released by or as a result of payment under such guarantees.

Section 4.23. Payments for Consents. Neither the Company nor any of its Subsidiaries or Affiliates will, directly or indirectly, pay or cause to be paid any consideration, whether by way of interest, fee or otherwise, to any Holder of any Notes for or as an inducement to any consent, waiver or amendment of any of the terms or provisions of the Indenture or the Notes unless such consideration is offered to be paid or agreed to be paid to all Holders of the Notes that consent, waive or agree to amend such term or provision in the time frame set forth in the solicitation documents relating to such consent, waiver or agreement.

Section 5.01. Consolidation, Merger or Sale of Assets by the Company.

(ii) the corporation formed by or surviving any such consolidation or merger (if other than the Company) or the corporation to which such sale, assignment, transfer, lease, conveyance or other disposition shall have been made assumes all the Obligations of the Company under the Notes and the Indenture pursuant to a supplemental indenture in form reasonably satisfactory to the Trustee;

(iii) immediately after such transaction no Default or Event of Default exists; and

(A) the Company or the entity or person formed by or surviving any such consolidation or merger (if other than the Company), or to which such sale, assignment, transfer, lease, conveyance or other disposition shall have been made, will have a Consolidated Net Worth immediately after the transaction equal to or greater than the Consolidated Net Worth of the Company immediately preceding the transaction, or

(B) except with respect to a consolidation or merger of the Company with or into a Person that has no outstanding Indebtedness, either (I) at the time of such transaction and after giving pro forma effect thereto as if such transaction had occurred at the beginning of the applicable four-quarter period, the Company or the entity or Person formed by or surviving any such consolidation or merger (if other than the Company), or to which such sale, assignment, transfer, lease, conveyance or other disposition shall have been made, will be permitted to incur at least $1.00 of additional Indebtedness pursuant to the Fixed Charge Coverage Ratio test set forth in Section 4.06(a) or (II) the Fixed Charge Coverage Ratio at the time of such transaction and after giving pro forma effect thereto as if such transaction had occurred at the beginning of the applicable four-quarter period will be equal to or greater than it was immediately before such transaction;

provided that this clause (iv) will terminate and cease to have any further effect from and after the first date when the Notes are rated Investment Grade.

The foregoing shall not prohibit the merger or consolidation of a Restricted Subsidiary of the Company with the Company; provided that, in connection with any such merger or consolidation, no consideration (other than common stock in the surviving Person or the Company) shall be issued or distributed to the stockholders of the Company.

(b) The Company will not lease all or substantially all its assets to another Person.

Section 5.02. Successor Company Substituted. (a) Except as provided in Section 5.02(b), upon any consolidation or merger, or any sale, assignment, transfer, conveyance or other disposition of all or substantially all the assets of the Company in accordance with Section 5.01 hereof, the successor corporation formed by such consolidation or into or with which the Company is merged or to which such sale, assignment, transfer, conveyance or other disposition is made shall succeed to, and be substituted for (so that from and after the date of such consolidation, merger, sale, assignment, transfer, conveyance or other disposition, the provisions of this Indenture referring to the “Company” shall refer instead to the successor corporation), and may exercise every right and power of, the Company under this Indenture with the same effect as if such successor Person had been named as the Company herein, and the predecessor Company shall be released from all its obligations hereunder and under the Notes.

(b) The sale, assignment, transfer, lease, conveyance or other disposition by the Company of all or substantially all its property or assets taken as a whole to one or more of the Company’s Subsidiaries shall not relieve the Company from its obligations under the Indenture and the Notes.

Section 5.03. Consolidation, Merger or Sale of Assets by a Subsidiary Guarantor.

(i) the Person formed by or surviving any such consolidation or merger (if other than the Company, another Subsidiary Guarantor or such Subsidiary Guarantor) assumes all the obligations of such Subsidiary Guarantor, pursuant to a supplemental indenture in form and substance reasonably satisfactory to the Trustee, under its Subsidiary Guarantee; or

(ii) immediately after giving effect to such transaction, no Default or Event of Default exists and the consolidation or merger results in such Subsidiary Guarantor no longer being a Subsidiary of the Company in compliance with this Indenture.

All the Subsidiary Guarantees issued pursuant to clause (i) above shall in all respects have the same legal rank and benefit under this Indenture as the Subsidiary Guarantees theretofore and thereafter issued in accordance with the terms of this Indenture as though all such Subsidiary Guarantees had been issued at the date of the execution hereof.

Section 6.01. Events of Default. Each of the following constitutes an “Event of Default”:

(a) a default in the payment of interest on the Notes when due, which has continued for 30 days;

(b) a default in the payment when due of principal of or premium on, any Note when due at its Stated Maturity, upon optional redemption, upon required repurchase, upon declaration or otherwise;

(d) the Company or any Subsidiary Guarantor defaults in the performance of or breaches any other covenant or agreement in this Indenture or under the Notes (other than (a), (b) or (c) above) and such default or breach continues for a period of 60 consecutive days after written notice by the Trustee or the Holders of 25% or more in aggregate principal amount of the Notes;

(e) any default under any mortgage, indenture or instrument under which there may be issued or by which there may be secured or evidenced any Indebtedness for money borrowed by the Company or any of its Significant Subsidiaries (or any Indebtedness for money borrowed Guaranteed by the Company or any of its Significant Subsidiaries if the Company or a Significant Subsidiary does not perform its payment obligations under such Guarantee within any grace period provided for in the documentation governing such Guarantee) and, whether such Indebtedness or Guarantee exists on the date of the indenture or is thereafter created, which default (a) constitutes a Payment Default or (b) results in the acceleration of such Indebtedness before its Stated Maturity, and in each case, the principal amount of any such Indebtedness, together with the principal amount of any other such Indebtedness under which there has been a Payment Default or that has been so accelerated, aggregates $50 million or more; provided, however, that if any such Payment Default is cured or waived or any such acceleration rescinded, or such Indebtedness is repaid, within a period of 10 days from the continuation of such Payment Default beyond the applicable grace period or the occurrence of such acceleration, as the case may be, such Event of Default shall be automatically rescinded, so long as such rescission does not conflict with any judgment or decree and the Notes have not been accelerated;

(f) failure by the Company or any of its Significant Subsidiaries to pay a final judgment or final judgments for the payment of money aggregating in excess of $50 million (net of any

amounts covered by insurance as to which the carrier has not contested coverage), which judgment or judgments are not paid, discharged or stayed for a period of 60 days;

(g) a court having jurisdiction in the premises enters a decree or order for (i) relief in respect of the Company or any Significant Subsidiary in an involuntary case under any applicable bankruptcy, insolvency or other similar Jaw now or hereafter in effect, (ii) appointment of a receiver, liquidator, assignee, custodian, trustee, sequestrator or similar official of the Company or any Significant Subsidiary or for all or substantially all the property and assets of the Company or any Significant Subsidiary or (iii) the winding up or liquidation of the affairs of the Company or any Significant Subsidiary and, in each case, such decree or order shall remain unstayed and in effect for a period of 60 consecutive days;

(h) the Company or any Significant Subsidiary (i) commences a voluntary case under any applicable bankruptcy, insolvency or other similar law now or hereafter in effect, or consents to the entry of an order for relief in an involuntary case under any such law, (ii) consents to the appointment of or taking possession by a receiver, liquidator, assignee, custodian, trustee, sequestrator or similar official of the Company or any Significant Subsidiary or for all or substantially all the property and assets of the Company or any Significant Subsidiary or (iii) effects any general assignment for the benefit of creditors; and

(i) except as permitted by this Indenture, any Subsidiary Guarantee of any Significant Subsidiary or any other group of Subsidiary Guarantors that together would be a Significant Subsidiary (after elimination of intercompany transactions and balances) shall be held in any judicial proceeding to be unenforceable or invalid or shall cease for any reason to be in full force and effect or any Subsidiary Guarantor, or any Person acting on behalf of any such Subsidiary Guarantor, shall deny or disaffirm its obligations under the Subsidiary Guarantees.

Section 6.02. Acceleration. If an Event of Default (other than an Event of Default specified in clause (g) or (h) of Section 6.01 that occurs with respect to the Company or any Subsidiary Guarantor) occurs and is continuing under this Indenture, the Trustee or the Holders of at least 25% in aggregate principal amount of the Notes then Outstanding, by written notice to the Company (and to the Trustee if such notice is given by the Holders (the “Acceleration Notice”)), may, and the Trustee at the request of such Holders shall, declare the principal of, premium, if any, and accrued but unpaid interest on all the Notes to be immediately due and payable. Upon a declaration of acceleration, such principal, premium, if any, and accrued interest shall be immediately due and payable. If an Event of Default specified in clause (g) or (h) of Section 6.01 occurs with respect to the Company or any Subsidiary Guarantor, the principal of, premium, if any, and accrued interest on the Notes then Outstanding shall ipso facto become and be immediately due and payable without any declaration or other act on the part of the Trustee or any Holder.

Section 6.03. Other Remedies. If an Event of Default occurs and is continuing, the Trustee may pursue any available remedy to collect the payment of principal or interest on the Notes or to enforce the performance of any provision of the Notes or this Indenture.

The Trustee may maintain a proceeding even if it does not possess any of the Notes or does not produce any of them in the proceeding. A delay or omission by the Trustee or any Holder in exercising any right or remedy accruing upon an Event of Default shall not impair the right or remedy or constitute a waiver of or acquiescence in the Event of Default. All remedies are cumulative to the extent permitted by law.

Section 6.04. Waiver of Past Defaults. The Holders of at least a majority in principal amount of the outstanding Notes, by written notice to the Company and to the Trustee, may waive all past defaults and rescind and annul a declaration of acceleration and its consequences under the Notes, if (i) all existing Events of Default, other than the nonpayment of the principal of and premium, if any, and interest on such Notes that have become due solely by such declaration of acceleration, have been cured or waived and (ii) the rescission would not conflict with any judgment or decree of a court of competent jurisdiction. Upon any such waiver, such Default shall cease to exist, and any Event of Default arising therefrom shall be

deemed to have been cured for every purpose of this Indenture; but no such waiver shall extend to any subsequent or other Default or impair any right consequent thereon.

Section 6.05. Control by Majority. The Holders of at least a majority in aggregate principal amount of the Outstanding Notes may direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or exercising any trust or power conferred on the Trustee. However, the Trustee may refuse to follow any direction that conflicts with law or this Indenture, that may involve the Trustee in personal liability, or that the Trustee determines in good faith may be unduly prejudicial to the rights of Holders not joining in the giving of such direction and may take any other action it deems proper that is not inconsistent with any such direction received from the Holders.

Section 6.06. Limitation on Suits. A Holder may not pursue any remedy with respect to this Indenture or the Notes unless:

(a) the Holder gives the Trustee written notice of a continuing Event of Default;

(b) the Holders of at least 25% in aggregate principal amount of Outstanding Notes make a written request to the Trustee to pursue the remedy;

(c) such Holder or Holders offer the Trustee security or indemnity satisfactory to it against any loss, liability or expense;

(d) the Trustee does not comply with the request within 60 days after receipt thereof and the offer of security or indemnity; and

(e) during such 60 day period, the Holders of at least a majority in aggregate principal amount of the Outstanding Notes do not give the Trustee a direction inconsistent with the request.

Section 6.07. Rights of Holders to Receive Payment. Notwithstanding any other provision of this Indenture, the right of any Holder to receive payment of principal, premium, if any, and interest on the Note, on or after the respective due dates expressed in the Note, or to bring suit for the enforcement of any such payment on or after such respective dates, shall not be impaired or affected without the consent of the Holder.

Section 6.08. Collection Suit by Trustee. If an Event of Default specified in Section 6.01(a) or (b) hereof occurs and is continuing, the Trustee is authorized to recover judgment in its own name and as trustee of an express trust against the Company or any other obligor for the whole amount of principal, premium, if any, and interest remaining unpaid on the Notes and interest on overdue principal and, to the extent lawful, interest and such further amount as shall be sufficient to cover amounts due the Trustee under Section 7.08, including the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel.

Section 6.09. Trustee May File Proofs of Claim. The Trustee is authorized to file such proofs of claim and other papers or documents as may be necessary or advisable in order to have the claims of the Trustee (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel) and the Holders allowed in any judicial proceedings relative to the Company (or any other obligor upon the Notes), its creditors or its property and shall be entitled and empowered to collect, receive and distribute any money or other property payable or deliverable on any such claims and any custodian in any such judicial proceeding is hereby authorized by each Holder to make such payments to the Trustee, and in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due to it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 7.08. To the extent that the payment of any such compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 7.08 out of the estate in any such proceeding, shall be denied for any reason,

payment of the same shall be secured by a Lien on, and shall be paid out of, any and all distributions, dividends, money, securities and other properties which the Holders may be entitled to receive in such proceeding whether in liquidation or under any plan of reorganization or arrangement or otherwise. Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the Notes or the rights of any Holder thereof, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding.

Section 6.10. Priorities. If the Trustee collects any money pursuant to this Article, it shall pay out the money in the following order:

First: to the Trustee, its agents and attorneys for amounts due under Section 7.08, including payment of all compensation, expense and liabilities incurred, and all advances made, by the Trustee and the costs and expenses of collection;

Second: to Holders for amounts due and unpaid on the Notes for principal, premium, if any, and interest, ratably, without preference or priority of any kind, according to the amounts due and payable on the Notes for principal, premium, if any, and interest, respectively; and

Third: to the Company or to such party as a court of competent jurisdiction shall direct.

The Trustee may fix a record date and payment date for any payment to Holders pursuant to this Section 6.10 upon five Business Days prior notice to the Company.

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 a 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 and expenses, against any party litigant in the suit, having due regard to the merits and good faith of the claims or defenses made by the party litigant. This Section does not apply to a suit by the Trustee, a suit by a Holder pursuant to Section 6.06, or a suit by Holders of more than 10% in aggregate principal amount of the then Outstanding Notes.

Section 6.12. Restoration of Rights and Remedies. If the Trustee or any Holder has instituted any proceeding to enforce any right or remedy under this Indenture or any Note and such proceeding has been discontinued or abandoned for any reason, or has been determined adversely to the Trustee or to such Holder, then and in every such case the Company, any other obligor upon the Notes, the Trustee and the Holders shall, subject to any determination in such proceeding, be restored severally and respectively to their former positions hereunder, and thereafter all rights and remedies of the Trustee and the Holders shall continue as though no such proceeding had been instituted.

Section 6.13. Rights and Remedies Cumulative. No right or remedy herein conferred upon or reserved to the Trustee or to the Holders is intended to be exclusive of any other right or remedy, and every right and remedy shall, to the extent permitted by law, be cumulative and in addition to every other right and remedy given hereunder or now or hereafter existing at law or in equity or otherwise. The assertion or employment of any right or remedy hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other appropriate right or remedy.

Section 6.14. Waiver of Stay, Extension or Usury Laws. The Company covenants (to the extent that it may lawfully do so) that it will not at any time insist upon, or plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay or extension law or any usury or other similar law wherever enacted, now or at any time hereafter in force, that would prohibit or forgive the Company from paying all or any portion of the principal of (or premium, if any) or interest on the Notes contemplated herein or in the Notes or that may affect the covenants or the performance of this Indenture; and the Company (to the extent that it may lawfully do so) hereby expressly waives all benefit or advantage

of any such law, and covenant 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 7.01. Certain Duties and Responsibilities. (a) Except during the continuance of an Event of Default,

(i) the Trustee need perform only those duties that are specifically set forth in this Indenture and no others, and no implied covenants or obligations shall be read into this Indenture against the Trustee; and

(ii) in the absence of bad faith on its part, the Trustee may conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon certificates or opinions furnished to the Trustee and conforming to the requirements of this Indenture. However, in the case of any such certificates or opinions which by any provision hereof are specifically required to be furnished to the Trustee, the Trustee shall examine the certificates and opinions to determine whether or not they conform to the requirements of this Indenture (but need not confirm or investigate the accuracy of mathematical calculations or other facts stated therein).

(b) In case an Event of Default has occurred and is continuing, the Trustee shall exercise such of the rights and powers vested in it by this Indenture, and use the same degree of care and skill in their exercise as a prudent person would exercise or use under the circumstances in the conduct of such person’s own affairs.

(c) No provision of this Indenture shall be construed to relieve the Trustee from liability for its own negligent action, its own negligent failure to act, or its own willful misconduct, except that (i) this paragraph does not limit the effect of Section 7.01(a); (ii) the Trustee shall not be liable for any error of judgment made in good faith by a Responsible Officer, unless it is proved that the Trustee was negligent in ascertaining the pertinent facts; and (iii) the Trustee shall not be liable with respect to any action it takes or omits to take in good faith in accordance with a direction received by it pursuant to Section 6.06.

(d) The Trustee may refuse to perform any duty or exercise any right or power or expend or risk its own funds or otherwise incur any financial liability unless it receives indemnity satisfactory to it against any loss, liability or expense.

(e) Whether or not therein expressly so provided, every provision of this Indenture relating to the conduct or affecting the liability of or affording protection to the Trustee shall be subject to the provisions of Sections 7.01 and 7.03.

Section 7.02. Notice of Defaults. (a) Within 90 days after the occurrence of any Default, the Trustee shall transmit by mail to all Holders, as their names and addresses appear in the Register, notice of such Default hereunder actually known to the Trustee unless such Default shall have been cured or waived; provided, however, that, except in the case of a Default in the payment of the principal of, premium (if any) or interest on, any Note, the Trustee may withhold such notice if and so long as the board of directors, the executive committee or a trust committee of Responsible Officers of the Trustee determines that the withholding of such notice is not opposed to the interests of the Holders.

(b) The Trustee shall not be required to take notice or be deemed to have notice or knowledge of any event or of any Default (except default in the payment of monies to the Trustee which are required to be paid to the Trustee on or before a specified date or within a specified time after receipt by

the Trustee of a notice or a certificate which was in fact received), unless a Responsible Officer of the Trustee has actual knowledge thereof or unless the Trustee shall receive from the Company or a Holder at the Corporate Trust Office written notice stating that the same has occurred and is continuing, specifying the same and referencing the Notes and this Indenture, and, in the absence of such knowledge or notice, the Trustee may conclusively assume that the same does not exist, except as aforesaid.

Section 7.03. Certain Rights of Trustee. Subject to the provisions of Section 7.01:

(i) the Trustee may conclusively rely and shall be protected in acting or refraining from acting upon any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, note, other evidence of indebtedness or other paper or document believed by it to be genuine and to have been signed or presented by the proper party or parties;

(iii) whenever in the administration of this Indenture the Trustee shall deem it desirable that a matter be proved or established prior to taking, suffering or omitting any action hereunder, the Trustee (unless other evidence be herein specifically prescribed) may, in the absence of bad faith on its part, rely upon the Officer’s Certificates of the Company;

(iv) the Trustee may consult with counsel of its selection and the advice of such counsel or any Opinion of Counsel with respect to legal matters relating to this Indenture and the Notes shall be full and complete authorization and protection in respect of any action taken, suffered or omitted by it hereunder in good faith and in reliance thereon;

(v) in case an Event of Default occurs and is continuing, the Trustee shall be under no obligation to exercise any of the rights or powers vested in it by this Indenture at the request or direction of any of the Holders pursuant to this Indenture, unless such Holders shall have offered to the Trustee security or indemnity satisfactory to it against any loss, liability or expense which might be incurred by it in compliance with such request or direction;

(vi) 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, note, other evidence of indebtedness or other paper or document, but the Trustee, in its reasonable discretion, may make further inquiry or investigation into such facts or matters, 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, upon reasonable notice to the Company and during normal business hours;

(vii) the Trustee may execute any of the trusts or powers hereunder or perform any duties hereunder either directly or by or through agents or attorneys and the Trustee shall not be responsible for any misconduct or negligence on the part of any agent or attorney appointed with due care by it hereunder;

(ix) the Trustee shall not be liable for any action taken, suffered, or omitted to be taken by it in good faith and reasonably believed by it to be authorized or within the discretion or rights or powers conferred upon it by this Indenture, unless the Trustee’s conduct constitutes willful misconduct or negligence; and

(x) the Trustee may request that the Company deliver a certificate setting forth the names of individuals and/or titles of officers authorized at such time to take specified actions pursuant to this Indenture.

Section 7.04. Not Responsible for Recitals or Issuance of Notes. The recitals contained herein and in the Notes, except the Trustee’s certificates of authentication, shall be taken as the statements of the Company, and neither the Trustee nor any Authenticating Agent assumes any responsibility for their correctness. The Trustee makes no representations as to the validity or sufficiency of this Indenture or of the Notes, except that the Trustee represents that it is duly authorized to execute and deliver this Indenture, authenticate the Notes and perform its obligations hereunder and that the statements made by it in a Statement of Eligibility and Qualification on Form T-1 supplied to the Company in connection with the registration of any Notes issued hereunder will be true and accurate subject to the qualifications set forth therein. Neither the Trustee nor any Authenticating Agent shall be accountable for the use or application by the Company of the Notes or the proceeds thereof.

Section 7.05. Trustee’s Disclaimer. The Trustee makes no representation as to the validity or adequacy of this Indenture or the Notes, it shall not be accountable for the Company’ use of the proceeds from the Notes, it shall not be responsible for any statement in the offering memorandum for the Notes or in the Indenture or the Notes (other than its certificate of authentication), the acts of a prior Trustee hereunder, or the determination as to which beneficial owners are entitled to receive any notices hereunder.

Section 7.06. May Hold Notes. The Trustee, any Authenticating Agent, any Paying Agent, any Registrar or any other agent of the Company, in its individual or any other capacity, may become the owner or pledgee of Notes and, subject to Section 7.09 and Section 7.14, may otherwise deal with the Company or its Affiliates with the same rights it would have if it were not Trustee, Authenticating Agent, Paying Agent, Registrar or such other agent.

Section 7.07. Money Held in Trust. Money held by the Trustee in trust hereunder need not be segregated from other funds except to the extent required by law. The Trustee shall be under no liability for interest on any money received by it hereunder except as otherwise agreed in writing with the Company.

(a) to pay to the Trustee from time to time such compensation as the Company and the Trustee shall from time to time agree in writing for all services rendered by it hereunder (which compensation shall not be limited by any provision of law in regard to the compensation of a trustee of an express trust);

(b) to reimburse the Trustee upon its request for all reasonable expenses, disbursements and advances incurred or made by the Trustee in accordance with any provision of this Indenture (including the reasonable compensation and the expenses, advances and disbursements of its agents and counsel), except any such expense, disbursement or advance as may be attributable to its negligence or bad faith; and

(c) to indemnify the Trustee and any predecessor Trustee for, and to hold it harmless against, any loss, damage, claims, liability or expense (including taxes, other than taxes based on the income of the Trustee) incurred without negligence or bad faith on its part, arising out of or in connection with the acceptance or administration of this trust, including the reasonable costs and expenses of defending itself against any claim (whether asserted by the Company, a Holder or any other person) or liability in connection with the exercise or performance of any of its powers or duties hereunder.

The Company’ payment obligations pursuant to this Section 7.08 shall survive the discharge of this Indenture. When the Trustee incurs expenses after the occurrence of a Default specified in Section 6.01(g) or 6.01(h), the expenses are intended to constitute expenses of administration under any applicable bankruptcy, insolvency or other similar law now or hereafter in effect.

Section 7.09. Conflicting Interests. If the Trustee has or shall acquire a conflicting interest within the meaning of the TIA, within 90 days the Trustee shall either eliminate such conflicting interest, apply to the SEC for permission to continue as Trustee with such conflicting interest, or resign, to the extent and in the manner provided by, and subject to the provisions of, the TIA and this Indenture. To the extent permitted by such Act, the Trustee shall not be deemed to have a conflicting interest by virtue of being a trustee under this Indenture with respect to Original Notes and Additional Notes, or a trustee under any other indenture between the Company and the Trustee.

Section 7.10. Corporate Trustee Required; Eligibility. (a) There shall at all times be one (and only one) Trustee hereunder. The Trustee shall be a Person that is eligible pursuant to the TIA to act as such and has a combined capital and surplus of at least $100,000,000. If any such Person publishes reports of condition at least annually, pursuant to law or to the requirements of its supervising or examining authority, then for the purposes of this Section 7.10 and to the extent permitted by the TIA, the combined capital and surplus of such Person shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. If at any time the Trustee shall cease to be eligible in accordance with the provisions of this Section 7.10, it shall resign immediately in the manner and with the effect hereinafter specified in this Article.

Section 7.11. Resignation and Removal; Appointment of Successor. (a) No resignation or removal of the Trustee and no appointment of a successor Trustee pursuant to this Article shall become effective until the acceptance of appointment by the successor Trustee in accordance with the applicable requirements of Section 7.12.

(b) The Trustee may resign at any time by giving written notice thereof to the Company. If the instrument of acceptance by a successor Trustee required by Section 7.12 shall not have been delivered to the Trustee within 30 days after the giving of such notice of resignation, the resigning Trustee may petition any court of competent jurisdiction for the appointment of a successor Trustee (and the Company shall reimburse the resigning Trustee for any reasonable out-of-pocket expenses that it incurs in connection with any such petition).

(c) The Trustee may be removed at any time by Act of the Holders of a majority in principal amount of the Outstanding Notes, delivered to the Trustee and to the Company. If the instrument of acceptance by a successor Trustee required by Section 7.12 shall not have been delivered to the Trustee within 30 days after the giving of such notice of removal, the Trustee being removed may petition any court of competent jurisdiction for the appointment of a successor Trustee (and the Company shall reimburse the Trustee being removed for any reasonable out-of-pocket expenses that it incurs in connection with any such petition).

(i) the Trustee shall fail to comply with Section 7.09 after written request therefor by the Company or by any Holder who has been a bona fide Holder for at least six months, or

(ii) the Trustee shall cease to be eligible under Section 7.10 and shall fail to resign after written request therefor by the Company or by any such Holder, or

(iii) the Trustee shall become incapable of acting or shall be adjudged bankrupt or insolvent or a receiver of the Trustee or of its property shall be appointed or any public officer shall take charge or control of the Trustee or of its property or affairs for the purpose of rehabilitation, conservation or liquidation,

then, in any such case, (A) the Company may remove the Trustee, or (B) subject to Section 6.11, any Holder who has been a bona fide Holder for at least six months may, on behalf of itself and all others similarly situated, petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee or Trustees.

(d) If the Trustee shall resign, be removed or become incapable of acting, or if a vacancy shall occur in the office of Trustee for any cause, the Company shall promptly appoint a successor Trustee and shall comply with the applicable requirements of Section 7.12. If, within one year after such resignation, removal or incapability, or the occurrence of such vacancy, a successor Trustee shall be appointed by Act of the Holders of a majority in principal amount of the Outstanding Notes delivered to the Company and the retiring Trustee, the successor Trustee so appointed shall, forthwith upon its acceptance of such appointment in accordance with the applicable requirements of Section 7.12, become the successor Trustee and to that extent supersede the successor Trustee appointed by the Company. If no successor Trustee shall have been so appointed by the Company or the Holders and accepted appointment in the manner required by Section 7.12, then, subject to Section 6.11, any Holder who has been a bona fide Holder for at least six months may, on behalf of itself and all others similarly situated, petition any court of competent jurisdiction for the appointment of a successor Trustee.

(e) The Company shall give notice of each resignation and each removal of the Trustee and each appointment of a successor Trustee to all Holders in the manner provided in Section 1.10. Each notice shall include the name of the successor Trustee and the address of its Corporate Trust Office.

Section 7.12. Acceptance of Appointment by Successor. (a) In case of the appointment hereunder of a successor Trustee, every such successor Trustee so appointed shall execute, acknowledge and deliver to the Company and to the retiring Trustee an instrument accepting such appointment, and thereupon the resignation or removal of the retiring Trustee shall become effective and such successor Trustee, without any further act, deed or conveyance, shall become vested with all the rights, powers, trusts and duties of the retiring Trustee; but, on the request of the Company or the successor Trustee, such retiring Trustee shall, upon payment of its charges, execute and deliver an instrument transferring to such successor Trustee all the rights, powers and trusts of the retiring Trustee and shall duly assign, transfer and deliver to such successor Trustee all property and money held by such retiring Trustee hereunder.

(b) Upon request of any such successor Trustee, the Company shall execute any and all instruments for more fully and certainly vesting in and confirming to such successor Trustee all such rights, powers and trusts referred to above.

(c) No successor Trustee shall accept its appointment unless at the time of such acceptance such successor Trustee shall be qualified and eligible under this Article 7.

Section 7.13. Merger, Conversion, Consolidation or Succession to Business. Any corporation into which the Trustee may be merged or converted or with which it may be consolidated, or any corporation resulting from any merger, conversion or consolidation to which the Trustee shall be a party, or any corporation succeeding to all or substantially all the corporate trust business of the Trustee, shall be the successor of the Trustee hereunder, provided such corporation shall be otherwise qualified and eligible under this Article 7, without the execution or filing of any paper or any further act on the part of any of the parties hereto. In case any Notes shall have been authenticated, but not delivered, by the Trustee then in office, any successor by merger, conversion or consolidation to such authenticating Trustee may adopt such authentication and deliver the Notes so authenticated with the same effect as if such successor Trustee had itself authenticated such Notes.

Section 7.14. Preferential Collection of Claims Against the Company. If and when the Trustee shall be or become a creditor of the Company (or any other obligor upon the Notes), the Trustee shall be subject to the provisions of the TIA regarding the collection of claims against the Company (or any such other obligor).

Section 7.15. Appointment of Authenticating Agent. The Trustee may appoint an Authenticating Agent acceptable to the Company to authenticate the Notes. Any such appointment shall be evidenced by an instrument in writing signed by a Responsible Officer, a copy of which instrument shall be promptly furnished to the Company. Unless limited by the terms of such appointment, an Authenticating Agent may authenticate Notes whenever the Trustee may do so. Each reference in this Indenture to authentication (or execution of a certificate of authentication) by the Trustee includes authentication (or

execution of a certificate of authentication) by such Authenticating Agent. An Authenticating Agent has the same rights as any Registrar, Paying Agent or agent for service of notices and demands.

Section 8.01. The Company to Furnish Trustee Names and Addresses of Holders; Stock Exchange Listing. (a) The Company will furnish or cause to be furnished to the Trustee

(i) semi-annually, not more than 15 days after each Regular Record Date, a list, in such form as the Trustee may reasonably require, of the names and addresses of the Holders as of such Regular Record Date, and

(ii) at such other times as the Trustee may request in writing, within 30 days after the receipt by the Company of any such request, a list of similar form and content as of a date not more than 15 days prior to the time such list is furnished;

provided, however, that if and so long as the Trustee shall be the Registrar, no such list need be furnished pursuant to this Section 8.01.

(b) The Company will promptly notify the Trustee when any Notes are listed on any stock exchange and of any delisting thereof.

Section 8.02. Preservation of Information; Communications to Holders. (a) The Trustee shall preserve, in as current a form as is reasonably practicable, the names and addresses of Holders contained in the most recent list, if any, furnished to the Trustee as provided in Section 8.01 and the names and addresses of Holders received by the Trustee in its capacity as Registrar; provided, however, that if and so long as the Trustee shall be the Registrar, the Register shall satisfy the requirements relating to such list. None of the Company, the Trustee or any other Person shall be under any responsibility with regard to the accuracy of such list. The Trustee may destroy any list furnished to it as provided in Section 8.01 upon receipt of a new list so furnished.

(b) The rights of Holders to communicate with other Holders with respect to their rights under this Indenture or under the Notes, and the corresponding rights and privileges of the Trustee, shall be as provided by the TIA.

(c) Every Holder, by receiving and holding the same, agrees with the Company and the Trustee that neither the Company nor the Trustee nor any agent of either of them shall be held accountable by reason of any disclosure of information as to names and addresses of Holders made pursuant to the TIA.

Section 8.03. Reports by Trustee. The Trustee shall transmit to Holders such reports concerning the Trustee and its actions under this Indenture as may be required pursuant to the TIA at the times and in the manner provided pursuant thereto. If required by Section 313(a) of the TIA, the Trustee shall, within 60 days after each May 15, following the date of this Indenture deliver to Holders a brief report, dated as of such May 15, which complies with the provisions of such Section 313(a). A copy of each such report shall, at the time of such transmission to Holders, be filed by the Trustee with each stock exchange, if any, upon which any Notes are listed, with the SEC and with the Company.

Section 9.01. Without Consent of the Holders. (a) Without the consent of any Holder, the Company, the Trustee and (if applicable) any Subsidiary Guarantor may enter into one or more indentures supplemental hereto, for any of the following purposes:

(ii) to provide for the assumption by a successor of the obligations of the Company under this Indenture,

(iii) to provide for uncertificated Notes in addition to or in place of certificated Notes; provided that the uncertificated Notes are issued in registered form for purposes of Section 163(f) of the Code, or in a manner such that the uncertificated Notes are described in Section 163(f)(2)(B) of the Code,

(iv) to add Subsidiary Guarantees with respect to the Notes, to grant a Lien under this Indenture to the Trustee as security for the Notes, to confirm and evidence the release, termination or discharge of any Subsidiary Guarantee or any such Lien with respect to or securing the Notes when such release, termination or discharge is permitted under this Indenture,

Section 9.02. With Consent of Holders. (a) Subject to Section 6.07, the Company, the Trustee and (if applicable) any Subsidiary Guarantor may amend or supplement this Indenture or the Notes with the written consent of the Holders of not less than a majority in aggregate principal amount of the Outstanding Notes, and any past Default or compliance with any provisions may also be waived with the written consent of the Holders of not less than a majority in aggregate principal amount of the Outstanding Notes.

(b) Notwithstanding the provisions of this Section 9.02, without the consent of each Holder affected, an amendment or waiver, including a waiver pursuant to Section 6.04, may not (with respect to any Notes held by a non-consenting Holder):

(i) change the Stated Maturity of the principal of, or any installment of interest on, any Note,

(ii) reduce the principal amount of or premium, if any, or interest on any Note,

(iii) reduce any amount payable on redemption of the Notes or upon the occurrence of an Event of Default or reduce the Change of Control Payment or the amount to be paid in connection with an Asset Sale Offer,

(iv) change the place or currency of payment of principal of or premium, if any, or interest on any Note,

(vii) waive a default in the payment of principal of or premium, if any, or interest on the Notes (except as set forth in Section 6.04),

(x) release any Subsidiary Guarantor from any of its obligations under its Subsidiary Guarantee or the Indenture other than in accordance with the provisions of the Indenture, or amend or modify any provision relating to such release.

(c) It shall not be necessary for the consent of the Holders under this Section 9.02 to approve the particular form of any proposed amendment, supplement or waiver, but it shall be sufficient if such consent approves the substance thereof.

(d) After an amendment, supplement or waiver under this Section 9.02 becomes effective, the Company shall mail to the Holders of each Note affected thereby, with a copy to the Trustee, a notice briefly describing the amendment, supplement or waiver. Any failure of the Company to mail such notice, or any defect therein, shall not, however, in any way impair or affect the validity of any supplemental indenture or the effectiveness of any such amendment, supplement or waiver.

Section 9.03. Execution of Amendments, Supplements or Waivers. The Trustee shall sign any amendment, supplement or waiver authorized pursuant to this Article 9 if the amendment, supplement or waiver does not adversely affect the rights, duties, liabilities or immunities of the Trustee. If it does, the Trustee may, but need not, sign it. In signing or refusing to sign such amendment, supplement or waiver, the Trustee shall be entitled to receive, and shall be fully protected in relying upon, an Officer’s Certificate and an Opinion of Counsel to the effect that the execution of such amendment, supplement or waiver has been duly authorized, executed and delivered by the Company and that such amendment, supplement or waiver is a valid and binding agreement of the Company, enforceable against it in accordance with its terms (subject to customary exceptions).

Section 9.04. Revocation and Effect of Consents. (a) Until an amendment, supplement or waiver becomes effective, a consent to it by a Holder is a continuing consent by the Holder and every subsequent Holder of that Note or any Note that evidences all or any part of the same debt as the consenting Holder’s Note, even if notation of the consent is not made on any Note. Subject to the following paragraph of this Section 9.04, any such Holder or subsequent Holder may revoke the consent as to such Holder’s Note by notice to the Trustee or the Company received by the Trustee or the Company, as the case may be, before the date on which the Trustee receives an Officer’s Certificate certifying that the Holders of the requisite principal amount of Notes have consented (and not theretofore revoked such consent) to the amendment, supplement or waiver. The Company may, but shall not be obligated to, fix a record date for the purpose of determining the Holders entitled to consent to any amendment, supplement or waiver as set forth in Section 1.08.

(b) After an amendment, supplement or waiver becomes effective, it shall bind every Holder, unless it makes a change described in any of clauses (i) through (viii) of Section 9.02(b). In that case, the amendment, supplement or waiver shall bind each Holder of a Note who has consented to it

and every subsequent Holder of such Note or any Note that evidences all or any part of the same debt as the consenting Holder’s Note.

Section 9.05. Conformity with TIA. Every amendment or supplemental indenture executed pursuant to this Article shall conform to the requirements of the TIA as then in effect.

Section 9.06. Notation on or Exchange of Notes. If an amendment, supplement or waiver changes the terms of a Note, the Trustee shall (if required by the Company and in accordance with the specific direction of the Company) request the Holder to deliver its Note to the Trustee. The Trustee shall (if required by the Company and in accordance with the specific written direction of the Company) place an appropriate notation on the Note about the changed terms and return it to the Holder. Alternatively, if the Company or the Trustee so determines, the Company in exchange for the Note shall issue and the Trustee shall authenticate a new Note that reflects the changed terms. Failure to make the appropriate notation or issue a new Note shall not affect the validity and effect of such amendment, supplement or waiver.

Section 10.01. Right of Redemption. Except as otherwise provided below, the Notes will not be redeemable at the option of the Company before , 20 . Thereafter, the Notes will be redeemable, at the option of the Company, in whole or in part, at any time or from time to time on and prior to maturity. Such redemption may be made upon notice mailed by first-class mail to each Holder’s registered address in accordance with Section 10.05. The Notes will be so redeemable at the following Redemption Prices (expressed as a percentage of principal amount on the relevant Redemption Date), plus accrued and unpaid interest to the relevant Redemption Date, if redeemed during the twelve-month period commencing on of the years set forth below:

Prior to , 20__, the Company may, at its option, on any one or more occasions, redeem up to % of the aggregate principal amount of the Notes (including any Additional Notes issued after the Issue Date) at a Redemption Price equal to % of the principal amount thereof, plus accrued and unpaid interest thereon to, but not including, the Redemption Date, with all or a portion of the net proceeds of one or more sales (other than to a Subsidiary or Joint Venture of the Company) of Qualified Equity Interests of the Company; provided that at least % of the aggregate principal amount of the Notes issued under this Indenture remains outstanding immediately after the occurrence of such redemption; and provided, further, that such redemption shall occur within 90 days of the date of the closing of any such sale of Qualified Equity Interests of the Company.

At any time prior to , 20 , the Company may also redeem, in whole or in part, the Notes at a Redemption Price equal to 100% of the principal amount of Notes to be redeemed, plus the Applicable Premium (as defined below) as of, and accrued and unpaid interest thereon to, but not including, the Redemption Date, subject to the rights of the Holders on the relevant record date to receive interest due on the relevant Interest Payment Date.

“Applicable Premium” means, with respect to any note on any Redemption Date, the excess of:

(1) the present value at such Redemption Date of (i) the Redemption Price of the Note on , 20 , plus (ii) all required interest payments due on the Note through , 20

(excluding accrued but unpaid interest to the Redemption Date) discounted back to the Redemption Date on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at a rate equal to the Treasury Rate as of such Redemption Date plus 50 basis points; over

“Treasury Rate” means, as of any Redemption Date, the yield to maturity as of such Redemption Date of United States Treasury securities with a constant maturity (as compiled and published in the most recent Federal Reserve Statistical Release H.15 (519) that has become publicly available at least two Business Days prior to the Redemption Date (or, if such Statistical Release is no longer published, any publicly available source of similar market data)) most nearly equal to the period from the Redemption Date to , 20 ; provided, however, that if the period from the Redemption Date to , 20 is less than one year, the weekly average yield on actually traded United States Treasury securities adjusted to a constant maturity of one year will be used.

Section 10.03. Election to Redeem; Notice to Trustee. In case of any redemption of the Notes at the election of the Company, the Company shall, at least 30 days prior to the Redemption Date initially fixed by the Company (unless a shorter notice shall be satisfactory to the Trustee), notify the Trustee of such Redemption Date and of the principal amount of Notes to be redeemed.

Section 10.04. Selection by Trustee of Notes to Be Redeemed. In the case of any partial redemption, selection of the Notes for redemption will be made not more than 60 days prior to the Redemption Date by the Trustee in compliance with the requirements of the principal national securities exchange, if any, on which the Notes are listed or, if the Notes are not so listed, on a pro rata basis, by lot or by such method as the Trustee shall deem fair and appropriate; provided that no Notes of $1,000 or less shall be redeemed in part.

(a) The Trustee shall promptly notify the Company in writing of the Notes selected for redemption and, in the case of any Note selected for partial redemption, the portion of the principal amount thereof to be redeemed. On and after the Redemption Date, interest will cease to accrue on Notes or portions thereof called for redemption.

(b) For all purposes of this Indenture, unless the context otherwise requires, all provisions relating to the redemption of Notes shall relate, in the case of any Note redeemed or to be redeemed only in part, to the portion of the principal of such Note that has been or is to be redeemed.

Section 10.05. Notice of Redemption. (a) Notice of redemption or purchase as provided in Section 10.01 shall be deemed to have been given upon the mailing by first class mail, postage prepaid, of such notice to each Holder of Notes to be redeemed, at its registered address as recorded in the Register, not later than 30 nor more than 60 days prior to the Redemption Date.

(iii) if less than all Outstanding Notes are to be redeemed, the identification (and, in the case of partial redemption, the respective principal amounts) of the particular Notes to be redeemed,

(iv) that on the Redemption Date the Redemption Price will become due and payable upon each such Note to be redeemed, and that, unless the Company defaults in making such redemption payment or any Paying Agent is prohibited from making such payment pursuant to the terms of this Indenture, interest thereon shall cease to accrue from and after said date,

(v) the place or places where such Notes are to be surrendered for payment of the Redemption Price and the name and address of the Paying Agent or Paying Agents,

(vi) the CUSIP and other security identification numbers, if any, subject to Section 3.12 hereof, and

(vii) the section of this Indenture pursuant to which the Notes are to be redeemed.

(b) Notice of such redemption or purchase of Notes to be so redeemed or purchased at the election of the Company shall be given by the Company or, at the written request of the Company delivered at least five Business Days prior to the date proposed for the mailing of such notice (unless a shorter notice shall be satisfactory to the Trustee), by the Trustee in the name and at the expense of the Company; provided that such notice to the Trustee may be revoked by the Company by written notice delivered to the Trustee prior to the date proposed for the mailing of the notice of such redemption to the Holders.

(c) The notice if mailed in the manner herein provided shall be conclusively presumed to have been given, whether or not the Holder receives such notice. In any case, failure to give such notice by mail or any defect in the notice to the Holder of any Note designated for redemption as a whole or in part shall not affect the validity of the proceedings for the redemption of any other Note.

Section 10.06. Deposit of Redemption Price. On or prior to 10:00 a.m., New York City time on any Redemption Date, the Company shall deposit with the Trustee or with a Paying Agent (or, if the Company is acting as its own Paying Agent, the Company shall segregate and hold in trust as provided in Section 4.03) an amount of money sufficient to pay the Redemption Price of, and any accrued and unpaid interest on, all the Notes or portions thereof which are to be redeemed on that date.

Section 10.07. Notes Payable on Redemption Date. (a) Notice of redemption having been given as provided in this Article 10, the Notes so to be redeemed shall, on the Redemption Date, become due and payable at the Redemption Price herein specified and from and after such date (unless Company shall default in the payment of the Redemption Price or any Paying Agent is prohibited from paying the Redemption Price pursuant to the terms of this Indenture) such Notes shall cease to bear interest. Upon surrender of such Notes for redemption in accordance with such notice, such Notes shall be paid by the Company at the Redemption Price. Installments of interest whose Interest Payment Date is on or prior to the Redemption Date shall be payable to the Holders of such Notes registered as such on the relevant Regular Record Dates according to their terms and the provisions of Section 3.07.

(b) On and after any Redemption Date, if money sufficient to pay the Redemption Price of and any accrued and unpaid interest on Notes called for redemption shall have been made available in accordance with Section 10.06, the Notes (or the portions thereof) called for redemption will cease to accrue interest and the only right of the Holders of such Notes (or portions thereof) will be to receive payment of the Redemption Price of, and subject to the last sentence of Section 10.07(a), any accrued and unpaid interest on such Notes (or portions thereof) to the Redemption Date. If any Note (or portion thereof) called for redemption shall not be so paid upon surrender thereof for redemption, the principal (and premium, if any) shall, until paid, bear interest from the Redemption Date at the rate borne by the Note (or portion thereof).

Section 10.08. Notes Redeemed in Part. Any Note that is to be redeemed only in part shall be surrendered at a Place of Payment (with, if the Company or the Trustee so requires, due endorsement by, or a written instrument of transfer in form satisfactory to the Company and the Trustee duly executed by, the Holder thereof or such Holder’s attorney duly authorized in writing) and the Company shall execute and the Trustee shall authenticate and deliver to the Holder of such Note without service charge, a new Note or Notes, of any authorized denomination as requested by such Holder in aggregate principal amount equal to and in exchange for the unredeemed portion of the principal of the Note so surrendered.

Section 11.01. Satisfaction and Discharge of Indenture. (a) This Indenture shall cease to be of further effect (except as to any surviving rights of transfer or exchange of Notes herein provided for), and the Trustee, on demand of and at the expense of the Company, shall execute proper instruments acknowledging satisfaction and discharge of this Indenture, when

(A) all Notes theretofore authenticated and delivered (other than (y) Notes that have been destroyed, lost or stolen and that have been replaced or paid as provided in Section 3.06, and (z) Notes for whose payment money has theretofore been deposited in trust or segregated and held in trust by the Company and thereafter repaid to the Company or discharged from such trust, as provided in Section 4.03) have been delivered to the Trustee canceled or for cancellation; or

(B) all such Notes not theretofore delivered to the Trustee canceled or for cancellation

(z) are to be called for redemption within one year under arrangements reasonably satisfactory to the Trustee for the giving of notice of redemption by the Trustee in the name, and at the expense, of the Company,

(ii) the Company has irrevocably deposited or caused to be deposited with the Trustee an amount in United States dollars, U.S. Government Obligations, or a combination thereof, sufficient to pay and discharge the entire Indebtedness on such Notes not theretofore delivered to the Trustee canceled or for cancellation, for principal (and premium, if any) and interest to the date of such deposit (in the case of Notes that have become due and payable), or to the Stated Maturity or Redemption Date, as the case may be;

(iii) the Company has paid or caused to be paid all other sums then payable hereunder by the Company; and

(iv) the Company has delivered to the Trustee an Officer’s Certificate and an Opinion of Counsel each to the effect that all conditions precedent provided for in this Section 11.01 relating to the satisfaction and discharge of this Indenture have been complied with; provided that any such counsel may rely on any Officer’s Certificate as to matters of fact (including as to compliance with the foregoing clauses (i), (ii) and (iii));

(b) Notwithstanding the satisfaction and discharge of this Indenture, the obligations of the Company to the Trustee under Section 7.08 and, if money shall have been deposited with the Trustee pursuant to clause (ii) of Section 11.01(a), the obligations of the Trustee under Section 11.02, shall survive.

Section 11.02. Application of Trust Money. Subject to the provisions of the last paragraph of Section 4.03, all money deposited with the Trustee pursuant to Section 11.01 shall be held in trust and applied by it, in accordance with the provisions of the Notes and this Indenture, to the payment, either directly or through any Paying Agent (including the Company acting as its own Paying Agent) as the Trustee may determine, to the Persons entitled thereto, of the principal (and premium, if any) and interest on the Notes; but such money need not be segregated from other funds except to the extent required by law.

Section 12.01. Option of the Company to Effect Defeasance or Covenant Defeasance. The Company may at its option by a Board Resolution, at any time, elect to have either Section 12.02 or Section 12.03 applied to the Outstanding Notes upon compliance with the conditions set forth below in this Article 12.

Section 12.02. Legal Defeasance and Discharge. Upon the exercise by the Company under Section 12.01 of the option applicable to this Section 12.02, the Company shall be deemed to have been discharged from any and all Obligations with respect to all Outstanding Notes (and any Subsidiary Guarantor will be discharged from any and all Obligations in respect of its Subsidiary Guarantee) on the date which is the 123rd day after the deposit referred to in Section 12.04(a); provided that all of the conditions set forth in Section 12.04 are satisfied (hereinafter, “Legal Defeasance”). For this purpose, such Legal Defeasance means that the Company shall be deemed to have paid and discharged the entire Indebtedness represented by the Outstanding Notes, which shall thereafter be deemed to be “outstanding” only for the purposes of Section 12.05 hereof and the other Sections of this Indenture referred to in clauses (i) and (ii) of this Section 12.02, and to have satisfied all its other obligations under such Notes and this Indenture (and the Trustee, on demand of and at the expense of the Company, shall execute proper instruments acknowledging the same), except for the following provisions which shall survive until otherwise terminated or discharged hereunder: (i) the rights of Holders of Outstanding Notes to receive solely from the trust fund described in Section 12.04 hereof, and as more fully set forth in such Section, payments in respect of the principal of, premium, if any, and interest on such Notes when such payments are due, (ii) the obligations of the Company with respect to such Notes under Sections 1.06, 3.03, 3.04, 3.05, 3.06, 3.13, 4.01, 4.02, 4.03 and 12.05 hereof, and (iii) the rights, powers, trusts, duties and immunities of the Trustee hereunder, including, without limitation, the Trustee’s rights under Section 7.08 hereof, and the obligations of the Company in connection therewith and with this Article 12. Subject to compliance with this Article 12, the Company may exercise its option under this Section 12.02 notwithstanding the prior exercise of its option under Section 12.03 hereof with respect to the Notes.

Section 12.03. Covenant Defeasance. Upon the exercise by the Company under Section 12.01 of the option applicable to this Section 12.03, the Company shall be released from its obligations under the covenants contained in Sections 4.06 through Section 4.18, Section 4.22, and clause (iv) of Section 5.01(a) hereof with respect to the Outstanding Notes and no Default under Section 6.01(e) and (f) shall thereafter constitute a Default or Event of Default on the date which is the 123rd day after the deposit referred to in Section 12.04(a); provided that all of the conditions set forth in Section 12.04 are satisfied (hereinafter, “Covenant Defeasance”), and the Notes shall thereafter be deemed not Outstanding for the purposes of any direction, waiver, consent or declaration or act of Holders (and the consequences of any thereof) in connection with such covenants, but shall continue to be deemed Outstanding for all other purposes hereunder. For this purpose, such Covenant Defeasance means that, with respect to the Outstanding Notes, the Company 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(c) or (d), but, except as specified above, the remainder of this Indenture and such Notes shall be unaffected thereby.

Section 12.04. Conditions to Legal or Covenant Defeasance. The following shall be the conditions to application of either Section 12.02 or Section 12.03 to the Outstanding Notes:

(a) the Company has deposited with the Trustee, in trust, money and/or U.S. Government Obligations that through the payment of interest and principal in respect thereof in accordance with their terms will provide money in an amount sufficient to pay (i) the principal of, premium, if any, and accrued interest on the Notes when such payments are due in accordance with the terms of this Indenture and the Notes or (ii) in the case of Legal Defeasance, accrued interest on the Notes through a scheduled redemption date and the principal of, and premium on the Notes on such redemption date; provided that, at the time of deposit, the Company irrevocably authorizes the Trustee to issue a timely notice of redemption and to take such other steps reasonably requested by the Trustee to ensure that such redemption will be effectuated;

(b) in the case of an election under Section 12.02, the Company has delivered to the Trustee (i) either (x) an Opinion of Counsel to the effect that Holders will not recognize income, gain or loss for Federal income tax purposes as a result of the exercise by the Company of its option under this Article 12 and will be subject to Federal income tax on the same amount and in the same manner and at the same times as would have been the case if such deposit, defeasance and discharge had not occurred, which Opinion of Counsel must be based upon (and accompanied by a copy of) a ruling of the Internal Revenue Service to the same effect unless there has been a change in applicable Federal income tax law after the date of this Indenture such that a ruling is no longer required or (y) a ruling directed to the Trustee received from the Internal Revenue Service to the same effect as the aforementioned Opinion of Counsel and (ii) an Opinion of Counsel to the effect that, as a result of the creation of the defeasance trust, the Company will not be required to register under the Investment Company Act of 1940 and after the passage of 123 days following the deposit, the trust fund will not be subject to the effect of Section 547 of the United States Bankruptcy Code or Section 15 of the New York Debtor and Creditor Law or any comparable provision of applicable law;

(c) in the case of an election under Section 12.03, the delivery by the Company to the Trustee of (i) an Opinion of Counsel to the effect that, among other things, the Holders will not recognize income, gain or loss for Federal income tax purposes as a result of such deposit and defeasance and will be subject to Federal income tax on the same amount and in the same manner and at the same times as would have been the case if such deposit and defeasance had not occurred and (ii) an Opinion of Counsel to the effect that, as a result of the creation of the defeasance trust, the Company will not be required to register under the Investment Company Act of 1940 and after the passage of 123 days following the deposit, the trust fund will not be subject to the effect of Section 547 of the United States Bankruptcy Code or Section 15 of the New York Debtor and Creditor Law or any comparable provision of applicable law;

(d) immediately after giving effect to such deposit on a pro forma basis, no Event of Default, or event that after the giving of notice or lapse of time or both would become an Event of Default, shall have occurred and be continuing on the date of such deposit or during the period ending on the 123rd day after the date of such deposit, and such deposit shall not result in a breach or violation of, or constitute a default under, any other agreement or instrument to which the Company is a party or by which the Company is bound;

(e) if at such time the Notes are listed on a national securities exchange, the Company has delivered to the Trustee an Opinion of Counsel to the effect that the Notes will not be delisted as a result of such deposit, defeasance and discharge;

(f) the Company shall have delivered to the Trustee Officer’s Certificates stating that the deposit made by the Company pursuant to its election under Sections 12.02 or 12.03 was not made

by the Company with the intent of preferring the Holders over the other creditors of the Company 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 Officer’s Certificates and an Opinion of Counsel, each stating that all conditions precedent provided for relating to either the Legal Defeasance under Section 12.02 or the Covenant Defeasance under Section 12.03 (as the case may be) have been complied with as contemplated by this Section 12.04.

Section 12.05. Deposited Money and Government Securities to Be Held in Trust; Other Miscellaneous Provisions. Subject to Section 12.06, all money and U.S. Government Obligations (including the proceeds thereof) deposited with the Trustee pursuant to Section 12.04 in respect of the Outstanding Notes shall be held in trust and applied by the Trustee, in accordance with the provisions of such Notes and this Indenture, to the payment, either directly or through any Paying Agent (including the Company acting as Paying Agent) as the Trustee may determine, to the Holders of such Notes of all sums due and to become due thereon in respect of principal of, 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 money or U.S. Government Obligations deposited pursuant to Section 12.04 hereof 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 Notes.

Anything in this Article 12 to the contrary notwithstanding, the Trustee shall deliver or pay to the Company from time to time upon the request of the Company any money or U.S. Government Obligations held by it as provided in Section 12.04 hereof 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 12.04(a) hereof), 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 12.06. 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 Note and remaining unclaimed for two years after such principal, premium, if any, or interest has become due and payable shall be paid to the Company on its written request or (if then held by the Company) shall be discharged from such trust; and the Holder of such Note 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, shall 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 notification or publication, any unclaimed balance of such money then remaining will be repaid to the Company.

Section 12.07. Reinstatement. If the Trustee or Paying Agent is unable to apply any money or U.S. Government Obligations in accordance with Section 12.02 or 12.03, 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 obligations of the Company under this Indenture and the Notes shall be revived and reinstated as though no deposit had occurred pursuant to Section 12.02 or 12.03 until such time as the Trustee or Paying Agent is permitted to apply all such amounts in accordance with Section 12.02 or 12.03 hereof, as the case may be; provided, however, that, if the Company makes any payment of principal of, premium, if any, or interest on any Note following the reinstatement of its Obligations, the Company shall be subrogated to the rights of the Holder of such Note to receive such payment from the amounts held by the Trustee or Paying Agent.

Section 13.01. The Guarantees. (a) Subject to the provisions of this Article 13, each Subsidiary Guarantor hereby irrevocably and unconditionally guarantees, jointly and severally, the full and punctual payment (whether at Stated Maturity, upon acceleration, optional redemption, upon repurchase following a Change of Control Offer or an Asset Sale Offer or otherwise) of the principal of and premium, if any, and interest on, and all other amounts payable under, each Note provided for under this Indenture, and the full and punctual payment of all other amounts payable by the Company under this Indenture. Upon failure by the Company to pay punctually any such amount, each Subsidiary Guarantor shall forthwith on demand pay the amount not so paid at the place and in the manner specified in this Indenture.

Section 13.02. Guarantee Unconditional. The obligations of the Subsidiary Guarantors hereunder shall be unconditional and absolute and, without limiting the generality of the foregoing, shall, to the fullest extent permitted by law, not be released, discharged or otherwise affected by:

(a) any extension, renewal, settlement, compromise, waiver or release in respect of any obligation of the Company under this Indenture or any Note, by operation of law or otherwise;

(b) any modification or amendment of or supplement to this Indenture or any Note; provided that any such modification which increases the obligations of each Subsidiary Guarantor hereunder shall not be effective as to such Subsidiary Guarantor without its consent;

(c) any release, impairment, non-perfection or invalidity of any direct or indirect security for any obligation of the Company or any Subsidiary Guarantor hereunder;

(d) any change in the corporate existence, structure or ownership of the Company, or any insolvency, bankruptcy, reorganization or other similar proceeding affecting the Company or its assets or any resulting release or discharge of any obligation of the Company contained in this Indenture or any Note;

(e) the existence of any claim, set-off or other rights which the Subsidiary Guarantors may have at any time against the Company, the Trustee or any other Person, whether in connection with this Indenture or any unrelated transactions, provided that nothing herein shall prevent the assertion of any such claim by separate suit or compulsory counterclaim;

(f) any invalidity or unenforceability relating to or against the Company for any reason of this Indenture or any Note, or any provision of applicable law or regulation purporting to prohibit the payment by the Company of the principal of or interest on any Note or any other amount payable by the Company under this Indenture; or

(g) any other act or omission to act or delay of any kind by the Company, the Trustee or any other Person or any other circumstance whatsoever which might, but for the provisions of this paragraph, constitute a legal or equitable discharge of or defense to such Subsidiary Guarantor’s obligations hereunder.

Section 13.03. Discharge; Reinstatement. The Subsidiary Guarantors’ obligations hereunder shall remain in full force and effect until the principal of, premium, if any, and interest on the Notes and all other amounts payable by the Company under this Indenture shall have been paid in full. If at any time any payment of the principal of, premium, if any, or interest on any Note or any other amount payable by the Company under this Indenture is rescinded or must be otherwise restored or returned upon the insolvency, bankruptcy or reorganization of the Company or otherwise, the Subsidiary Guarantors’ obligations hereunder with respect to such payment shall be reinstated as though such payment had been due but not made at such time.

Section 13.04. Waiver by the Subsidiary Guarantors. The Subsidiary Guarantors irrevocably waive acceptance hereof, presentment, demand, protest and any notice not provided for herein, as well as any requirement that at any time any action be taken by any Person against the Company or any other Person.

Section 13.05. Subrogation and Contribution. Upon making any payment with respect to any obligation of the Company under this Article 13, the Subsidiary Guarantor making such payment shall be subrogated to the rights of the payee against the Company with respect to such obligation; provided that such Subsidiary Guarantor shall not enforce either (i) any right to receive payment by way of subrogation against the Company or against any direct or indirect security for such obligation, or any other right to be reimbursed, indemnified or exonerated by or for the account of the Company in respect thereof or (ii) any right to receive payment, in the nature of contribution or for any other reason, from any other Subsidiary Guarantor with respect to such payment, in each case so long as any amount payable by the Company hereunder or under the Notes remains unpaid.

Section 13.06. Stay of Acceleration. If acceleration of the time for payment of any amount payable by the Company under this Indenture or the Notes is stayed upon the insolvency, bankruptcy or reorganization of the Company, all such amounts otherwise subject to acceleration under the terms of this Indenture shall nonetheless be payable by the Subsidiary Guarantors hereunder forthwith on demand by the Trustee or the Holders.

Section 13.07. Limits of Guarantees. Notwithstanding anything to the contrary in this Article 13, each Subsidiary Guarantor, and by its acceptance of Notes, each Holder, hereby confirms that it is the intention of all such parties that the Subsidiary Guarantee of such Guarantor not constitute a fraudulent conveyance under applicable fraudulent conveyance provisions of the United States Bankruptcy Code or any comparable provision of state law. To effectuate the foregoing intention, the Trustee, the Holders and the Subsidiary Guarantors hereby irrevocably agree that the obligations of such Subsidiary Guarantor under its Subsidiary Guarantee and this Article 13 shall be limited to the maximum amount that would not render such Subsidiary Guarantor’s obligations subject to avoidance under applicable fraudulent conveyance provisions of the United States Bankruptcy Code or any comparable provision of state law.

Section 13.08. Execution and Delivery of Note Guarantee. To evidence its Subsidiary Guarantee set forth in Section 13.01, each Subsidiary Guarantor hereby agrees that this Indenture (or a supplemental indenture in the form of Exhibit B hereto) shall be executed on behalf of such Subsidiary Guarantor by one of its Officers.

The signature of an Officer of a Subsidiary Guarantor on the Indenture shall bind such Subsidiary Guarantor, notwithstanding that such individual has ceased to hold such office prior to the authentication and delivery of any Note or did not hold such office at the date of such Note.

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

IN WITNESS WHEREOF, the parties hereto have caused this Indenture to be duly executed, all as of the date first written above.

With respect to Physical Notes, the Company will make all payments of principal, premium, if any, and interest at the office or agency maintained by the Company for such purposes in The City of New York or, at the Company’s option, by mailing a check to each such Holder’s registered address. If a payment date is a date other than a Business Day, payment may be made at that place on the next succeeding day that is a Business Day and no interest shall accrue for the intervening period.

(3) Paying Agent and Registrar. Initially, the Trustee will act as Paying Agent and Registrar. The Company may change any Paying Agent or Registrar upon written notice thereto. The Company, any Subsidiary or any Affiliate of any of them may act as Paying Agent, Registrar or co-registrar.

(4) Indenture; Limitations. The Company issued the Notes under an Indenture dated as of , 20 (as amended, supplemented or otherwise modified from time to time, the “Indenture”), among the Company, the Subsidiary Guarantors and , as trustee (the “Trustee”). Capitalized terms herein are used as defined in the Indenture unless otherwise indicated. The terms of the Notes include those stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act of 1939 (the “TIA”). The Notes are subject to all such terms, and Holders are referred to the Indenture and the TIA for a statement of all such terms. To the extent permitted by applicable law, in the event of any inconsistency between the terms of this Note and the terms of the Indenture, the terms of the Indenture shall control.

The Notes are secured senior obligations of the Company. The Indenture limits the initial aggregate principal amount of the Notes to $ but permits the issuance of Additional Notes subject to compliance with certain conditions and covenants contained in the Indenture and except as may be limited by applicable law.

(5) Optional Redemption. The Notes may be redeemed at the option of the Company, in whole or in part, at any time and from time to time, on or after , 20__, at the following Redemption Prices (expressed in percentages of principal amount on the relevant Redemption Date), plus accrued and unpaid interest to the Redemption Date, if redeemed during the 12-month period commencing of each of the years set forth below:

Prior to , 20__, the Company may, at its option, on any one or more occasions, redeem up to % of the aggregate principal amount of the Notes (including any Additional Notes issued after the Issue Date) at a Redemption Price equal to % of the principal amount thereof, plus accrued and unpaid interest thereon to, but not including, the Redemption Date, with all or a portion of the net proceeds of one or more sales (other than to a Subsidiary or Joint Venture of the Company) of Qualified Equity Interests of the Company; provided that at least 65% of the aggregate principal amount of the Notes issued under the Indenture remains outstanding immediately after the occurrence of such redemption; and provided, further, that such redemption shall occur within 90 days of the date of the closing of any such sale of Qualified Equity Interests of the Company.

At any time prior to , 20__, the Company may also redeem, in whole or in part, the Notes at a Redemption Price equal to 100% of the principal amount of Notes to be redeemed, plus the Applicable Premium (as defined below) as of, and accrued and unpaid interest thereon to, but not including, the Redemption Date, subject to the rights of the Holders on the relevant record date to receive interest due on the relevant Interest Payment Date.

“Applicable Premium” means, with respect to any note on any Redemption Date, the excess of:

(1) the present value at such Redemption Date of (i) the Redemption Price of the Note on , 20__, plus (ii) all required interest payments due on the Note through , 20 (excluding accrued but unpaid interest to the Redemption Date) discounted back to the Redemption Date on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at a rate equal to the Treasury Rate as of such Redemption Date plus 50 basis points; over

“Treasury Rate” means, as of any Redemption Date, the yield to maturity as of such Redemption Date of United States Treasury securities with a constant maturity (as compiled and published in the most recent Federal Reserve Statistical Release H.15 (519) that has become publicly available at least two Business Days prior to the Redemption Date (or, if such Statistical Release is no longer published, any publicly available source of similar market data)) most nearly equal to the period from the Redemption Date to , 20__; provided, however, that if the period from the Redemption Date to , 20 is less than one year, the weekly average yield on actually traded United States Treasury securities adjusted to a constant maturity of one year will be used.

If less than all the Notes are to be redeemed at any time, selection of Notes for redemption will be made by the Trustee in compliance with the requirements of the principal national securities exchange, if any, on which the Notes are listed or, if the Notes are not so listed, on a pro rata basis, by lot or by such method as the Trustee shall deem fair and appropriate; provided that no Notes of $1,000 or less shall be redeemed in part.

Notices of redemption shall be mailed by first class mail at least 30 but not more than 60 days before the redemption date to each Holder of Notes to be redeemed at its registered address. Redemption may be subject to one or more conditions precedent. If any Note is to be redeemed in part only, the notice of redemption that relates to such Note shall state the portion of the principal amount thereof to be redeemed. A new Note in principal amount equal to the unredeemed portion thereof will be issued in the name of the Holder thereof upon cancellation of the original Note. Notes called for redemption become due on the date fixed for redemption. On and after the redemption date, interest ceases to accrue on Notes or portions of them called for redemption.

(6) Repurchase upon a Change in Control and Sale of Assets. Upon the occurrence of (a) a Change in Control, each Holder shall have the right to require that the Company repurchase such Holder’s Notes at a purchase price in cash equal to 101% of the principal amount thereof on the date of purchase, plus accrued and unpaid interest to the date of purchase and (b) an Asset Sale, the Company may be obligated to make an offer to purchase on a pro rata basis from the Holders the Notes with the Excess Proceeds of such Asset Sales at a purchase price equal to 100% of the principal amount of such Notes plus accrued interest to the date of purchase.

(7) Denominations; Transfer; Exchange. The Notes are in fully registered form without coupons, in denominations of $1,000 and any integral multiples of $1,000. A Holder may register the transfer or exchange of Notes in accordance with the Indenture. The Registrar may require a Holder, among other things, to furnish appropriate endorsements and transfer documents and to pay any taxes and fees required by law or permitted by the Indenture.

(8) Persons Deemed Owners. A Holder may be treated as the owner of a Note for all purposes.

(9) Unclaimed Money. If money for the payment of principal, premium, if any, or interest remains unclaimed for two years, the Trustee and the Paying Agent will pay the money back to the Company at its written request. After that, Holders entitled to the money must look to the Company for payment, unless an abandoned property law designates another Person, and all liability of the Trustee and such Paying Agent with respect to such money shall cease.

(10) Discharge Prior to Redemption or Maturity. If the Company irrevocably deposits, or causes to be deposited, with the Trustee money or U.S. Government Obligations sufficient to pay the then outstanding principal of and premium, if any, and accrued interest on the Notes (a) to redemption or maturity, the Company will be discharged from the Indenture and the Notes, except in certain circumstances for certain sections thereof, and (b) to redemption or maturity, the Company will be discharged from certain covenants set forth in the Indenture.

(11) Amendment; Supplement; Waiver. Subject to certain exceptions, the Indenture or the Notes may be amended or supplemented with the consent of the Holders of at least a majority in aggregate

principal amount of the Notes then Outstanding, and any existing Default or compliance with any provision may be waived with the consent of the Holders or a majority in aggregate principal amount of the Notes then Outstanding. Without notice to or the consent of any Holder, the parties thereto may amend the Indenture or the Notes to the extent set forth in the Indenture.

(12) Restrictive Covenants. The Indenture contains certain covenants, including, without limitation, covenants with respect to the following matters: (i) Indebtedness; (ii) Restricted Payments; (iii) distributions from Restricted Subsidiaries and Joint Ventures; (iv) sales of assets; (v) transactions with Affiliates; (vi) Liens; (vii) no amendment to subordination provisions; (viii) repurchase of Notes upon a Change in Control; (ix) Sale and Leaseback Transactions; (x) Subsidiary Guarantees; and (xi) consolidation, merger and sale of assets. Within 120 days after the end of each fiscal year, the Company must report to the Trustee on compliance with such limitations.

(13) Successor Persons. When a successor person or other entity (other than a Subsidiary of the Company) assumes all the obligations of its predecessor under the Notes and the Indenture, the predecessor person will be released from those obligations.

(14) Remedies for Events of Default. If an Event of Default (other than an Event of Default specified in Section 6.01(g) or (h) of the Indenture that occurs with respect to the Company or a Subsidiary Guarantor) occurs and is continuing under this Indenture, then in every such case the Trustee or the Holders of at least 25% in aggregate principal amount of the Outstanding Notes, by written notice to the Company (and to the Trustee if such notice is given by the Holders), may, and the Trustee at the written request of such Holders shall, declare the principal of, premium, if any, and accrued interest on all of the Outstanding Notes to be immediately due and payable. Upon a declaration of acceleration, such principal of, premium, if any, and accrued interest shall be immediately due and payable. If an Event of Default specified in Section 6.01(g) or (h) of the Indenture occurs with respect to the Company or a Subsidiary Guarantor, the principal of, premium, if any, and accrued interest on the Outstanding Notes shall ipso facto become and be immediately due and payable without any declaration or other act on the part of the Trustee or any Holder. The Holders of at least a majority in aggregate principal amount of the Outstanding Notes by written notice to the Company and to the Trustee, may waive all past defaults and rescind and annul a declaration of acceleration and its consequences if (1) all existing Events of Default, other than the nonpayment of the principal of, premium, if any, and interest on the Notes that have become due solely by such declaration of acceleration, have been cured or waived and (2) the rescission would not conflict with any judgment or decree of a court of competent jurisdiction.

Holders may not enforce the Indenture, the Notes or the Subsidiary Guarantees except as provided in the Indenture. The Trustee may require security or indemnity satisfactory to it before it enforces the Indenture, the Notes or the Subsidiary Guarantees. The Holders of at least a majority in aggregate principal amount of the Notes then Outstanding may direct the Trustee in the exercise of any trust or power in accordance with the terms of the Indenture.

(15) Subsidiary Guarantees. Each Subsidiary Guarantor irrevocably and unconditionally guarantees, jointly and severally, on a senior basis, the full and punctual payment (whether at Stated Maturity, upon acceleration, optional redemption, upon repurchase following a Change of Control Offer or an Asset Sale Offer or otherwise) of the principal of, premium, if any, and interest on, and all other amounts payable under, this Note provided for under this Indenture, and the full and punctual payment of all other amounts payable by the Company under the Indenture; provided that, notwithstanding anything to the contrary herein, the aggregate amount of the Obligations guaranteed under the Indenture by any Subsidiary Guarantor shall be limited in amount to the maximum amount that would not render such Subsidiary Guarantor’s obligations subject to avoidance under the applicable fraudulent conveyance provisions of the United States Bankruptcy Code or any comparable provision of any applicable state law.

(16) Additional Subsidiary Guarantees. If any of the Company’s Restricted Subsidiaries shall Guarantee or secure the payment of any other Indebtedness of the Company or any of its Restricted Subsidiaries, then, subject to certain exceptions specified in the Indenture, such Restricted Subsidiary shall become a Subsidiary Guarantor by executing a supplemental indenture.

(17) Trustee Dealings with Company. The Trustee under the Indenture, in its individual or any other capacity, may become the owner or pledgee of Notes and may make loans to, accept deposits from, perform services for, and otherwise deal with, the Company and its Affiliates as if it were not the Trustee.

(18) Authentication. This Note shall not be valid until the Trustee signs the certificate of authentication on this Note.

(19) Abbreviations. Customary abbreviations may be used in the name of a Holder or an assignee, such as: TEN COM (= tenants in common), TEN ENT (= tenants by the entireties), JT TEN (= joint tenants with right of survivorship and not as tenants in common), COST (= Custodian) and U/G/M/A (= Uniform Gifts to Minors Act).

(20) Governing Law. This Note shall be governed by and construed in accordance with the internal laws of the State of New York, without giving effect to any principles of conflict of laws to the extent that the application of the law of another jurisdiction is required thereby.

The Company will furnish to any Holder upon written request and without charge a copy of the Indenture. Requests may be made to the Company, One Houston Center, Suite 700, 1221 McKinney, Houston, Texas 77010; Attention: General Counsel.
