THIS AMENDED & RESTATED SUPPLEMENTAL INDENTURE (this “Supplemental Indenture”), dated as of June 24, 2014, among Laredo Petroleum, Inc., a corporation duly organized and existing under the laws of the State of Delaware (herein called the “Company”) having its principal office at 00 Xxxx Xxxxx Xxxxxx, Xxxxx 000, Xxxxx, Xxxxxxxx 00000, the Existing Guarantor (as defined hereinafter), having its principal office at 00 Xxxx Xxxxx Xxxxxx, Xxxxx 000, Xxxxx, Xxxxxxxx 00000, and Xxxxx Fargo Bank, National Association, as trustee (the “Trustee”).

RECITALS

WHEREAS, on April 27, 2012, the Company (then known as “Laredo Petroleum Holdings, Inc.” (“Laredo Holdings”)), a Delaware corporation then known as “Laredo Petroleum, Inc.” and predecessor by merger to the Company (“LPI”), Laredo Gas Services, LLC, a Delaware limited liability company (“Laredo Gas”), Laredo Petroleum Texas, LLC, a Texas limited liability company (“Laredo Texas”), and Laredo Petroleum—Dallas, Inc., a Delaware corporation (“Laredo Dallas” and, together with Laredo Holdings, Laredo Gas and Laredo Texas, the “Initial Guarantors”), and the Trustee entered into a supplemental indenture dated as of April 27, 2012 (the “Original Supplemental Indenture”), supplementing that certain base indenture previously entered into by LPI, the Initial Guarantors and the Trustee dated April 27, 2012 (the “Original Base Indenture”) and providing for the issuance by LPI of its 7⅜% Senior Notes due 2022 (the “Notes”), which Original Supplemental Indenture referred therein to (i) LPI, being the issuer of the Notes, as the “Company” and (ii) Laredo Holdings, being the parent of LPI and a Guarantor of the Notes, as the “Parent Guarantor”;

WHEREAS, on April 27, 2012, LPI issued $500,000,000 in aggregate principal amount of Notes under the Original Supplemental Indenture;

WHEREAS, (i) on December 17, 2013, Laredo Gas changed its name to Laredo Midstream Services, LLC (“Laredo Midstream” or the “Existing Guarantor”), (ii) on December 31, 2013, pursuant to the Agreement and Plan of Merger, dated as of December 31, 2013, by and among LPI, Laredo Dallas and Laredo Texas, Laredo Dallas and Laredo Texas merged with and into LPI, with LPI as the surviving entity, (iii) thereupon, on December 31, 2013, pursuant to Section 253 of the Delaware General Corporation Law, on December 31, 2013 and effective as of the time set forth in the Certificate of Merger filed with the Secretary of State of the State of Delaware, LPI merged with and into Laredo Holdings, with Laredo Holdings as the surviving entity; and (iv) thereupon, on December 31, 2013, pursuant to such Certificate of Merger, Laredo Holdings changed its name to Laredo Petroleum, Inc. (such mergers in clauses (ii) and (iii) together constituting the “Restructuring Mergers”);

WHEREAS, pursuant to Section 901 of the Original Base Indenture and Section 8.01 of the Original Supplemental Indenture, the Original Base Indenture and the Original Supplemental Indenture have been further supplemented by that certain Second Supplemental Indenture, dated as of December 31, 2013 (the “Second Supplemental Indenture”), pursuant to which, as a result of LPI merging into Laredo Holdings with Laredo Holdings constituting the surviving entity, Laredo Holdings assumed all obligations of LPI (and thereupon became the “Company”) under the Original Base Indenture and the Original Supplemental Indenture and Laredo Midstream confirmed its guarantee of the Original Base Indenture and the Original Supplemental Indenture

- 1 -

and the Notes (the Original Base Indenture, as supplemented by the Second Supplemental Indenture, the “Base Indenture”; the Original Supplemental Indenture, as supplemented by the Second Supplemental Indenture, the “Existing Supplemental Indenture”; the Base Indenture, as supplemented by the Existing Supplemental Indenture, the “Existing Indenture”; and the Existing Indenture, as supplemented by this Supplemental Indenture, referred to herein as the “Indenture”);

WHEREAS, pursuant to Section 901 of the Base Indenture and Section 8.01 of the Existing Supplemental Indenture, the Company, Laredo Midstream, and the Trustee, when authorized by a board resolution of the Company (and, in the case of the Base Indenture, when authorized by a Board Resolution of each Guarantor), at any time and from time to time, may amend or supplement the Existing Indenture without the consent of any Holder of a Note to, among other things, make any provision with respect to matters or questions arising under the Existing Indenture, the Notes or any Guarantee; provided that such provisions shall not adversely affect the interest of the Holders of the Notes in any material respect;

WHEREAS, on January 15, 2014, an Unrestricted Global Note substantially in the form of Exhibit A1 to this Amended & Restated Supplemental Indenture and representing in the aggregate $500,000,000 of the Notes was exchanged for an Unrestricted Global Note substantially in the form of Exhibit A1 to the Existing Supplemental Indenture and of a like aggregate principal amount, all to reflect the Second Supplemental Indenture and the succession by the Company to the Company’s predecessor under the Existing Indenture (i.e., LPI) and the assumption by the Company of the covenants in the Existing Indenture and the Notes of the Company’s predecessor (i.e., LPI) pursuant thereto;

WHEREAS, as a result of the Restructuring Mergers, (i) the entity formerly constituting the “Parent Guarantor” under the Existing Indenture is now the same entity as the “Company” thereunder; (ii) there is no other Guarantor now existing under the Existing Indenture other than Laredo Midstream; and (iii) therefore, references in the Existing Indenture to (x) the “Parent Guarantor” are redundant in certain cases where both the “Company” and the “Parent Guarantor” are referred to or are ambiguous or unclear in certain other cases where the “Parent Guarantor” is referred to even though such entity no longer exists separately from the “Company”; (y) the “Company” are ambiguous or unclear in certain cases where the “Company” is referred to as if the Company were a subsidiary of another obligor on the Notes (i.e., the “Parent Guarantor”) even though the Company is now itself the parent of any other obligor on the Notes or (z) “Subsidiary Guarantor” are ambiguous or unclear in certain cases where “Subsidiary Guarantor” is referred to as if there may be another type of “Guarantor” of the Notes that is not a Subsidiary of the Company (e.g., a “Parent Guarantor”) even though the only entity that is now, or pursuant to Section 4.12 of the Existing Supplemental Indenture will in the future be, a Guarantor of the Notes is a Subsidiary of the Company;

WHEREAS, the Company and Laredo Midstream wish to amend and restate the Existing Supplemental Indenture to make provision with respect to such matters of redundancy in the Existing Indenture by eliminating such references to the “Parent Guarantor” and with respect to matters of ambiguity or lack of clarity in the Existing Indenture by changing such references to the “Parent Guarantor” to the “Company”, changing such references to “Subsidiary Guarantor” to “Guarantor” or eliminating such references to the “Company”, as applicable, in each case, only so long as such provision shall not adversely affect the interest of the Holders of the Notes in any material respect;

- 2 -

WHEREAS, the Company has furnished the Trustee with (i) an Officers’ Certificate and (ii) an Opinion of Counsel and the Guarantor has furnished the Trustee with a Guarantor’s Officers’ Certificate, each of such documents in form and substance reasonably satisfactory to the Trustee and stating that, in the opinion of such signers or such counsel, as applicable, all conditions precedent, if any, provided for in the Existing Indenture with respect to the execution and delivery of this Amended & Restated Supplemental Indenture have been satisfied and that this Amended & Restated Supplemental Indenture is authorized or permitted by the Existing Indenture; and

WHEREAS, all things necessary have been done to make this Amended & Restated Supplemental Indenture, when executed and delivered by the Company and Laredo Midstream, the legal, valid and binding agreement of the Company and Laredo Midstream, in accordance with its terms.

NOW, THEREFORE, in consideration of the foregoing and for other good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, the Company, Laredo Midstream and the Trustee mutually covenant and agree to amend and restate the Existing Supplemental Indenture in its entirety as follows for the benefit of the other parties and for the equal and ratable benefit of the Holders of the Notes:

Article One

Issue and Description of Notes

Section 1.01 Designation and Amount; Ranking Payments; Denomination. The Notes shall be designated as the “7⅜% Senior Notes due 2022.” The Notes are hereby established as a series of Securities under the Base Indenture. The aggregate principal amount of Notes that may be authenticated and delivered under this Supplemental Indenture is not limited. The aggregate principal amount of Notes initially authorized for authentication and delivery pursuant to this Supplemental Indenture (the “Initial Notes”) is limited to $500,000,000 (except for Notes authenticated and delivered upon registration or transfer of, or in exchange for, or in lieu of other Notes pursuant to Section 1.11, Section 3.06 and Section 8.05 hereof and Section 304, Section 305 and Section 306 of the Base Indenture). The Company may, and shall be entitled to, from time to time, without notice to or the consent of the Holders of the Notes, in accordance with Section 1.03 below increase the principal amount of Notes and issue such increased principal amount (or any portion thereof) of Notes as “Additional Notes” under this Supplemental Indenture.

Payments of the principal of and interest on the Notes shall be made in U.S. Dollars, and the Notes shall be denominated in Dollars and in amounts of at least $2,000 and integral multiples of $1,000 thereafter. The Place of Payment where the principal of and any other payments due on the Notes are payable shall initially be at the office or agency of the Company maintained for that purpose in New York, New York in accordance with Section 4.01 of this Supplemental Indenture.

Initially, Xxxxx Fargo Bank, N.A. will act as Paying Agent and Registrar. The Company may appoint and change any Paying Agent or Registrar or co-registrar without notice. The Company or any of its domestically organized Wholly-Owned Restricted Subsidiaries may act as Paying Agent or Registrar or co-registrar.

The Company shall pay interest (a) on any Definitive Notes by check mailed to the address of the Person entitled thereto as it appears in the Security Register (or upon written application by such Person to the Paying Agent not later than five Business Days before the relevant Interest Payment Date, by wire transfer in immediately available funds to such Person’s account at a

- 3 -

bank in New York, New York, if such Person is entitled to interest on an aggregate principal amount in excess of $1,000,000, which application shall remain in effect until the Holder notifies the Paying Agent to the contrary) or (b) on any Global Note by wire transfer of immediately available funds to the account of the Depositary or its nominee.

The Notes shall be guaranteed by each of the Initial Guarantors and, in accordance with Section 4.12 hereof, any additional Subsidiary Guarantors in accordance with Section 4.12 and Article Nine of this Supplemental Indenture.

No Guarantee nor any notation thereof shall be, or shall be required to be, endorsed on, or attached to, or otherwise physically made part of any Note.

Section 1.02 Form of Notes. The Notes shall be substantially in the forms set forth in, as applicable, Exhibit A1 or Exhibit A2 hereto, each of which is incorporated in and made a part of this Supplemental Indenture.

Any of the Notes may have such letters, numbers or other marks of identification and such notations, legends or endorsements as the officers executing the same may approve (execution thereof to be conclusive evidence of such approval) and as are not inconsistent with the provisions of this Supplemental Indenture or the Base Indenture or as may be required to comply with any law or with any rule or regulation made pursuant thereto or with any rule or regulation of any securities exchange or automated quotation system on which the Notes may be listed or designated for issuance, or to conform to usage or to indicate any special limitations or restrictions to which any particular Notes are subject.

The terms and provisions contained in the forms of Note attached as Exhibit A1 and Exhibit A2 hereto shall constitute, and are hereby expressly made, a part of this Supplemental Indenture and the Company and the Trustee, by their execution and delivery of this Supplemental Indenture, expressly agree to such terms and provisions and to be bound thereby. However, to the extent any provision of any Note conflicts with the express provisions of the Indenture, the provisions of the Indenture shall govern and be controlling.

Notes issued in global form shall be substantially in the form of Exhibit A1 or A2 attached hereto (including the Global Note Legend thereon and the “Schedule of Exchanges of Interests in the Global Note” attached thereto). Each Global Note shall represent such of the outstanding Notes as shall be specified therein and each shall provide that it shall represent the aggregate principal amount of outstanding Notes from time to time endorsed thereon and that the aggregate principal amount of outstanding Notes represented thereby may from time to time be

- 4 -

reduced or increased, as appropriate, to reflect exchanges and redemptions. Any endorsement of a Global Note to reflect the amount of any increase or decrease in the aggregate principal amount of outstanding Notes represented thereby shall be made by the Trustee in accordance with instructions given by the Holder thereof as required by Section 1.11.

Definitive Notes shall be substantially in the form of Exhibit A1 attached hereto (but without the Global Note Legend thereon and without the “Schedule of Exchanges of Interests in the Global Note” attached thereto).

Section 1.03 Additional Notes.

(a) The Company shall be entitled, subject to its compliance with Article Four, to issue Additional Notes under this Supplemental Indenture. Any Additional Notes shall be part of the same series as the Initial Notes issued on the Issue Date, rank equally with the Initial Notes and have identical terms and conditions to the Initial Notes in all respects other than (a) the date of issuance, (b) the issue price, (c) rights under a related Registration Rights Agreement, if any, and (d) at the option of the Company, (i) as to the payment of interest accruing prior to the issue date of such Additional Notes, and (ii) the first payment of interest following the issue date of such Additional Notes.

(b) With respect to any Additional Notes, there shall be (a) established in or pursuant to a Board Resolution and (b) (i) set forth or determined in the manner provided in an Officers’ Certificate or (ii) established in one or more indentures supplemental to the Indenture, prior to the issuance of such Additional Notes:

(ii) the issue price, the issue date (and the corresponding date from which interest shall accrue thereon and the first interest payment date therefor) and the CUSIP or ISIN number of such Additional Notes;

(iii) whether such Additional Notes shall be subject to the restrictions on transfer set forth in Section 1.11 relating to Restricted Global Notes and Restricted Definitive Notes; and

(iv) if applicable, that such Additional Notes shall be issuable in whole or in part in the form of one or more Global Notes and, in such case, the respective depositaries for such Global Notes, the form of any legend or legends which shall be borne by such Global Notes in addition to or in lieu of those set forth in, as applicable, Exhibit A1 or Exhibit A2 hereto and any circumstances in addition to or in lieu of those set forth in, as applicable, Exhibit A1 or Exhibit A2 in which any such Global Notes may be exchanged in whole or in part for Additional Notes registered, or any transfer of such Global Note in whole or in part may be registered, in the name or names of Persons other than the depositary for such Global Note or a nominee thereof.

- 5 -

(c) If any of the terms of any Additional Notes are established by action taken pursuant to a Board Resolution, a copy thereof shall be delivered to the Trustee at or prior to the delivery of the Officers’ Certificate or the indenture supplemental to the Indenture setting forth the terms of the Additional Notes.

(d) The Initial Notes and any Additional Notes subsequently issued upon original issue under this Indenture and all Exchange Notes issued in exchange therefor shall be considered collectively as a single class for all purposes of the Indenture, including directions, waivers, amendments, consents, redemptions and offers to purchase. Holders of the Initial Notes and any Additional Notes and all Exchange Notes issued in exchange therefor will vote and consent together on all matters to which such Holders are entitled to vote or consent as one class, and none of the Holders of the Initial Notes or any Additional Notes or any Exchange Notes issued in exchange therefor shall have the right to vote or consent as a separate class on any matter to which such Holders are entitled to vote or consent.

(e) Notwithstanding anything else herein, with respect to any Additional Notes issued subsequent to the Issue Date, when the context requires, (1) all references in this Article One herein and elsewhere in this Supplemental Indenture to a Registration Rights Agreement shall be to the registration rights agreement entered into with respect to such Additional Notes, (2) any references in this Supplemental Indenture to the Exchange Offer, Exchange Offer Registration Statement, Shelf Registration Statement, Initial Purchasers, and any other term related thereto shall be to such terms as they are defined in such Registration Rights Agreement entered into with respect to such Additional Notes, (3) all time periods described in the Notes with respect to the registration of such Additional Notes shall be as provided in such Registration Rights Agreement entered into with respect to such Additional Notes, (4) any Additional Interest, if set forth in such Registration Rights Agreement, may be paid to the Holders of the Additional Notes immediately prior to the making or the consummation of the Exchange Offer regardless of any other provisions regarding record dates herein and (5) all provisions of this Supplemental Indenture shall be construed and interpreted to permit the issuance of such Additional Notes and to allow such Additional Notes to become fungible and interchangeable with the Initial Notes originally issued under the Supplemental Indenture (and Exchange Notes issued in exchange therefor). Indebtedness represented by Additional Notes shall be subject to the covenants contained in this Supplemental Indenture.

Section 1.04 Execution and Authentication.

(a) One Officer shall sign the Notes for the Company by manual or facsimile signature.

(b) The Initial Notes may forthwith be executed by the Company and delivered to the Trustee for authentication and delivery by the Trustee for original issue upon a Company Order in accordance with the provisions of Section 303 of the Base Indenture.

(c) At any time and from time to time after the issuance of the Initial Notes, the Trustee shall authenticate and deliver any Additional Notes for original issue without limit as to the aggregate principal amount thereof, subject to compliance with Section 4.07, in

- 6 -

accordance with the provisions of Section 103 and Section 303 of the Base Indenture in an aggregate principal amount determined at the time of issuance and specified in a Company Order. Such Company Order shall specify the principal amount of the Additional Notes to be authenticated and the date on which the original issue of such Additional Notes is to be authenticated.

(d) Upon receipt of a Company Order, the Trustee shall authenticate for original issue (i) Exchange Notes in exchange for Initial Notes in an aggregate principal amount not to exceed $500,000,000 or (ii) Exchange Notes in exchange for Additional Notes in an aggregate principal amount not to exceed the aggregate principal amount of such Additional Notes so exchanged; provided that such Exchange Notes shall be issuable only upon the valid surrender for cancellation of Initial Notes issued on the Issue Date or Additional Notes, as the case may be, of a like aggregate principal amount in accordance with an Exchange Offer pursuant to an applicable Registration Rights Agreement.

(e) If an Officer whose signature is on a Note no longer holds that office at the time a Note is authenticated, the Note shall nevertheless be valid.

(f) A Note shall not be valid until authenticated by the manual signature of the Trustee. Such signature shall be conclusive evidence that the Note has been authenticated under this Supplemental Indenture. A Note shall be dated the date of its authentication.

(g) The Trustee may appoint an authenticating agent acceptable to the Company to authenticate Notes. An authenticating agent may authenticate Notes whenever the Trustee may do so. Each reference in the Indenture to authentication by the Trustee includes authentication by such agent. An authenticating agent has the same rights as an Agent to deal with Holders or an Affiliate of the Company.

(h) The Trustee shall also authenticate and deliver Notes at the times and in the manner specified in Section 1.06, Section 1.11, Section 3.06, Section 4.11(h), Section 4.17(c) and Section 8.05 and Section 306 of the Base Indenture.

Section 1.05 Non-Business Day Payments. If any Interest Payment Date, the Stated Maturity, any Redemption Date, any Asset Sale Purchase Date or any Change of Control Purchase Date falls on a day that is not a Business Day, then the required payment or delivery will be made on the next succeeding Business Day with the same force and effect as if made on the date that the payment or delivery was due, and no additional interest will accrue on that required payment or delivery for the period from and after the Interest Payment Date, Stated Maturity, Redemption Date, Asset Sale Purchase Date or Change of Control Purchase Date, as the case may be, to that next succeeding Business Day.

Section 1.06 Temporary Global Notes; Euroclear and Clearstream Procedures Applicable.

(a) Until certificates representing Notes are ready for delivery, the Company may prepare and the Trustee shall authenticate temporary Notes. Temporary Notes shall be substantially in the form of Definitive Notes but may have variations that the Company considers appropriate for temporary Notes. Without unreasonable delay, the Company shall

- 7 -

prepare and the Trustee shall authenticate and deliver Definitive Notes in exchange for temporary Notes. Holders of temporary Notes shall be entitled to all of the benefits of the Indenture.

(b) To the extent required by Regulation S, Notes offered and sold in reliance on Regulation S shall be issued initially in the form of the Regulation S Temporary Global Note, which shall be deposited on behalf of the purchasers of the Notes represented thereby with the Trustee, as custodian for DTC, and registered in the name of the Depositary or the nominee of the Depositary for the accounts of designated agents holding on behalf of Euroclear or Clearstream, duly executed by the Company and authenticated by the Trustee as hereinafter provided. The Restricted Period shall be terminated upon the receipt by the Trustee of an Officers’ Certificate from the Company certifying that the Restricted Period may be terminated in accordance with Regulation S and that beneficial interests in the Regulation S Temporary Global Note are permitted to be exchanged for beneficial interests in Regulation S Permanent Global Notes. Following the termination of the Restricted Period, beneficial interests in the Regulation S Temporary Global Note shall be exchanged for beneficial interests in Regulation S Permanent Global Notes pursuant to the Applicable Procedures. Simultaneously with the authentication of Regulation S Permanent Global Notes, the Trustee shall cancel the Regulation S Temporary Global Note. The aggregate principal amount of the Regulation S Temporary Global Note and the Regulation S Permanent Global Notes may from time to time be increased or decreased by adjustments made on the records of the Trustee and the Depositary or its nominee, as the case may be, in connection with transfers of interest as hereinafter provided.

(c) The provisions of the “Operating Procedures of the Euroclear System” and “Terms and Conditions Governing Use of Euroclear” and the “General Terms and Conditions of Clearstream” and “Customer Handbook” of Clearstream shall be applicable to transfers of beneficial interests in the Regulation S Temporary Global Note and the Regulation S Permanent Global Notes that are held by Participants through Euroclear or Clearstream.

Section 1.07 Methods of Receiving Payments on the Notes. The principal of (and premium, if any) and interest (including Additional Interest, if any) on the Notes shall be payable at the office or agency of the Company maintained for such purpose pursuant to Section 4.01; provided, however, that (i) payments in respect of the Notes represented by the Global Notes (including principal, premium, if any, and interest) shall be made by wire transfer of immediately available funds to the accounts specified by the Depositary with respect thereto; and (ii) payments in respect of the Notes represented by any Definitive Notes (including principal, premium, if any, and interest) shall be made (subject (in the case of payments of principal or premium, if any) to surrender of such Note at such office or agency): (a) if the Holder thereof has specified by written notice to the Trustee a U.S. dollar account maintained by such Holder with a bank located in the United States for such purpose no later than 15 days immediately preceding the relevant payment date (or such later date as the Trustee may accept in its discretion), by wire transfer of immediately available funds to such account so specified or (b) otherwise, at the option of the Company, by check mailed to the Holder of such Note at its address set forth in the Securities Register.

Section 1.08 Registrar and Paying Agent.

- 8 -

(a) The Company shall maintain in the continental United States an office or agency where Notes may be presented for registration of transfer or for exchange (“Registrar”) and an office or agency where Notes may be presented for payment (“Paying Agent”). The Registrar shall keep a register of the Notes and of their transfer and exchange (the “Securities Register”). The Company may appoint one or more co-registrars and one or more additional paying agents. The term “Registrar” includes any co-registrar and the term “Paying Agent” includes any additional paying agent. The Company may change any Paying Agent or Registrar without prior notice to any Holder.

All Global Notes shall be exchanged by the Company for Definitive Notes if (i) the Company delivers to the Trustee notice from the Depositary that it is unwilling or unable to continue to act as Depositary or that it is no longer a clearing agency registered under the Exchange Act and, in either case, a successor Depositary is not appointed by the Company within 90 days after the date of such notice from the Depositary; or (ii) there shall have occurred and be continuing an Event of Default and the Depositary notifies the Trustee of its decision to exchange the Global Notes for Definitive Notes; provided that a beneficial interest in the Regulation S Temporary Global Note may not be exchanged for Definitive Notes or transferred to a Person who takes delivery thereof in the form of a Definitive Note prior to (A) the expiration of the Restricted Period and (B) the receipt by the Registrar of any certificates required pursuant to Rule 903(b)(3)(ii)(B) under the Securities Act. Except as provided in the preceding sentence, and notwithstanding any contrary indication this Section 1.11, beneficial interests in a Global Note may be exchanged for Definitive Notes only with the consent of the Company upon delivery of a written notice to such effect to the Trustee, including if an affiliate (as defined in Rule 144) of the Company acquires such interests. Upon the occurrence of any of the preceding events in (i) or (ii) above or upon the consent of the Company as provided in the preceding sentence, Definitive Notes shall be issued in such names as the Depositary shall instruct the Trustee. Global Notes also may be exchanged or replaced, in whole or in part, as provided in Section 1.06, Section 3.06, Section 4.11(h), Section 4.17(c) and Section 8.05 and Section 306 of the Base Indenture.

Whenever any provision herein (including Section 3.06, Section 4.11 or Section 4.17) refers to issuance by the Company and authentication and delivery by the Trustee of a new Note in exchange for the portion of a surrendered Note that has not been redeemed or repurchased, as the case may be, in lieu of the surrender of any Global Note and the issuance, authentication and delivery of a new Global Note in exchange therefor, the Trustee or the Depositary at the direction of the Trustee may endorse such Global Note to reflect a reduction in the principal amount represented thereby in the amount of Notes so represented that have been so redeemed or repurchased.

- 10 -

Notwithstanding the foregoing, nothing herein shall prevent the Company, the Trustee or any agent of the Company or the Trustee from giving effect to any written certification, proxy or other authorization furnished by the Depositary or impair, as between the Depositary and its Participants or the Indirect Participants, the operation of customary practices of such Depositary governing the exercise of the rights of a holder of a beneficial interest in any Global Note. Subject to the provisions of this Section 1.11 and Section 11.11, the Holder of a Global Note shall be entitled to grant proxies and otherwise authorize any Person, including Participants and Indirect Participants and Persons that may hold interests through such Persons, to take any action that a Holder is entitled to take under this Supplemental Indenture or the Notes. Beneficial interests in the Restricted Global Notes shall be subject to restrictions on transfer comparable to those set forth herein to the extent required by the Securities Act.

(d) If the Paying Agent (other than the Company, a Subsidiary of the Company or an Affiliate of any of the foregoing) holds, on a redemption date or other Maturity, money

- 25 -

sufficient to pay Notes payable on that date, then on and after that date such Notes shall be deemed to be no longer outstanding and shall cease to accrue interest.

Section 1.13 Treasury Notes. In determining whether the Holders of the required principal amount of Notes have concurred in any direction, waiver or consent, Notes owned by the Company, or by any Person directly or indirectly controlling or controlled by or under direct or indirect common control with the Company, shall be considered as though not outstanding, except that for the purposes of determining whether the Trustee shall be protected in relying on any such direction, waiver or consent, only Notes that any of its Responsible Officers knows are so owned shall be so disregarded.

Section 1.14 Defaulted Interest. If the Company defaults in a payment of interest on the Notes, it shall pay the defaulted interest in any lawful manner plus, to the extent lawful, interest payable on the defaulted interest, to the Persons who are Holders on the record date for the interest payment or a subsequent special record date, in each case at the rate provided in the Notes and in Section 4.01.

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 sentence, such manner of payment shall be deemed practicable by the Trustee.

- 35 -

calculate the Consolidated Fixed Charge Coverage Ratio is such an Asset Sale, the Consolidated Net Income for such period will be reduced by an amount equal to the Consolidated Net Income (Loss) (if positive) directly attributable to the assets which are the subject of such Asset Sale for such period or increased by an amount equal to the Consolidated Net Income (Loss) (if negative) directly attributable thereto for such period and Consolidated Interest Expense for such period shall be reduced by an amount equal to the Consolidated Interest Expense directly attributable to any Indebtedness of the Company or any Restricted Subsidiary repaid, repurchased, defeased or otherwise discharged with respect to the Company and the continuing Restricted Subsidiaries in connection with or with the proceeds from such Asset Sale for such period (or, if the Capital Stock of any Restricted Subsidiary is sold, the Consolidated Interest Expense for such period directly attributable to the Indebtedness of such Restricted Subsidiary to the extent the Company and the continuing Restricted Subsidiaries are no longer liable for such Indebtedness after such sale);

(4)if, since the beginning of such period, any Person (that subsequently became a Restricted Subsidiary or was merged with or into the Company or any Restricted Subsidiary since the beginning of such period) made any Asset Sale or any Investment or acquisition of assets that would have required an adjustment pursuant to clause (2) or (3) above if made by the Company or a Restricted Subsidiary during such period, Consolidated Net Income (Loss) and Consolidated Interest Expense for such period will be calculated after giving pro forma effect thereto as if such Asset Sale or Investment or acquisition of assets had occurred on the first day of such period.

For purposes of this definition, whenever pro forma effect is to be given to any calculation under this definition, the pro forma calculations will be determined in good faith by a responsible financial or accounting officer of the Company; provided that such officer may in his or her discretion include any reasonably identifiable and factually supportable pro forma changes to Consolidated Net Income (Loss), including any pro forma expenses and cost reductions, that have occurred or in the judgment of such officer are reasonably expected to occur within 12 months of the date of the applicable transaction (regardless of whether such expense or cost reduction or any other operating improvements could then be reflected properly in pro forma financial statements prepared in accordance with Regulation S-X under the Securities Act or any other regulation or policy of the Commission); and provided further that

For purposes of this Supplemental Indenture, the term “Company Website” means the collection of web pages that may be accessed on the World Wide Web using the URL address xxxx://xxx.xxxxxxxxxxx.xxx or such other address as the Company may from time to time designate in writing to the Trustee.

Section 4.07 Incurrence of Indebtedness and Issuance of Disqualified Stock.

(a) The Company will not, and will not cause or permit any Restricted Subsidiary to, create, issue, incur, assume, guarantee or otherwise in any manner become directly or indirectly liable for the payment of or otherwise incur, contingently or otherwise (collectively, “incur”), any Indebtedness (including any Acquired Debt and the issuance of Disqualified Stock or the issuance of Preferred Stock by a Restricted Subsidiary), unless such Indebtedness is incurred by the Company or any Guarantor and, in each case, after giving pro forma effect to such incurrence and the receipt and application of the proceeds therefrom, the

- 77 -

Company’s Consolidated Fixed Charge Coverage Ratio for the most recent four full fiscal quarters for which financial statements are available immediately preceding the incurrence of such Indebtedness taken as one period would be equal to or greater than 2.25 to 1.0.

(b) Notwithstanding the foregoing, the Company and, to the extent specifically set forth below, the Restricted Subsidiaries may incur each and all of the following (collectively, the “Permitted Debt”):

(1)    Indebtedness of the Company or any Guarantor (whether as borrowers or guarantors) under one or more Credit Facilities in an aggregate principal amount at any one time outstanding not to exceed the greater of (x) $250.0 million and (y) the sum of $100.0 million and 30% of Adjusted Consolidated Net Tangible Assets determined as of the date of the incurrence of such Indebtedness;

(3)    Indebtedness of the Company or any Guarantor outstanding on the Issue Date, and not otherwise referred to in this definition of “Permitted Debt”;

(4)    intercompany Indebtedness between or among the Company and any Restricted Subsidiary; provided, however, that:

(a)    if the Company or any Guarantor is the obligor on such Indebtedness and such Indebtedness is owed to a Restricted Subsidiary other than a Guarantor, such Indebtedness shall be either (x) expressly subordinated to the prior payment in full in cash of all obligations with respect to the Notes, in the case of the Company, or the Guarantees, in the case of a Guarantor, or (y) Capital Stock; and

(b)    any subsequent issuance or transfer of Capital Stock that results in any such Indebtedness being held by a Person other than the Company or a Restricted Subsidiary (other than pursuant to a Credit Facility) and 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, that was not permitted by this clause (4);

(5)    guarantees by the Company or any Guarantor of any Indebtedness of the Company or any Restricted Subsidiary that is permitted to be incurred under the Indenture;

(6)    Indebtedness of the Company or any Restricted Subsidiary represented by Capital Lease Obligations (whether or not incurred pursuant to sale and leaseback transactions) or Purchase Money Obligations or other Indebtedness incurred or assumed in connection with the acquisition, construction, improvement or development of real or

personal, movable or immovable, property, in each case incurred for the purpose of financing or Refinancing all or any part of the purchase price or cost of acquisition, construction, improvement or development of property used in the business of the Company or any Restricted Subsidiary (together with improvements, additions, accessions and contractual rights relating primarily thereto), in an aggregate principal amount outstanding at any time pursuant to this clause (6) not to exceed the greater of (x) $25.0 million and (y) 2.0% of Adjusted Consolidated Net Tangible Assets determined as of the date of the incurrence of such Indebtedness;

(7)    Indebtedness of the Company or any Restricted Subsidiary in connection with (a) one or more standby letters of credit issued by the Company or a Restricted Subsidiary in the ordinary course of business and (b) other self-insurance obligations, letters of credit, surety, bid, performance, appeal or similar bonds, bankers’ acceptances, completion guarantees or similar instruments and any guarantees or letters of credit functioning as or supporting any of the foregoing instruments; provided that, in each case contemplated by this clause (7), upon the drawing of such letters of credit or other instrument, such obligations are reimbursed within 30 days following such drawing; provided further that with respect to clauses (a) and (b), such Indebtedness is not in connection with the borrowing of money;

(8)    Indebtedness of the Company or any Guarantor; provided that sufficient net proceeds thereof are promptly deposited to effect a Legal Defeasance or Covenant Defeasance with respect to all of the Notes pursuant to Article Seven or a Satisfaction and Discharge with respect to all of the Notes pursuant to Article Ten;

(9)    Permitted Refinancing Indebtedness of the Company or any Guarantor issued to Refinance any Indebtedness, including any Disqualified Stock, incurred pursuant to Section 4.07(a) and clauses (2), (3), (11) and this clause (9) of this paragraph (b) of this Section 4.07;

(13)    Preferred Stock (other than Disqualified Stock) of the Company or any Restricted Subsidiary; and

(14)    Indebtedness of the Company or any Restricted Subsidiary in addition to that described in clauses (1) through (13) above, so long as the aggregate principal amount of all such Indebtedness incurred pursuant to this clause (14) outstanding at any one time in the aggregate shall not exceed the greater of (x) $35.0 million and (y) 2.5% of Adjusted Consolidated Net Tangible Assets determined as of the date of the incurrence of such Indebtedness.

- 79 -

(c) For purposes of determining compliance with this Section 4.07, in the event that an item of Indebtedness meets the criteria of more than one of the categories of “Permitted Debt” or is permitted to be incurred pursuant to paragraph (a) of this Section 4.07, the Company in its sole discretion may classify or reclassify (or later classify or reclassify) in whole or in part such item of Indebtedness in any manner (including by dividing and classifying such item of Indebtedness in more than one type of Indebtedness permitted under this Section 4.07) that complies with this Section 4.07; provided that Indebtedness under the Senior Credit Agreement, if any, which is in existence on the Issue Date shall be considered incurred under clause (1) of paragraph (b) of this Section 4.07, subject to any subsequent classification or reclassification or division permitted pursuant to this paragraph (c).

(d) Indebtedness permitted by this Section 4.07 need not be permitted solely by reference to one provision permitting such Indebtedness but may be permitted in part by one such provision and in part by one or more other provisions of this Section 4.07 permitting such Indebtedness.

(e) Accrual of interest, accretion or amortization of original issue discount or accretion of principal as to a security issued at a discount and the payment of interest on any Indebtedness in the form of additional Indebtedness with the same terms, the accretion or payment of dividends on any Disqualified Stock or Preferred Stock in the form of additional shares of the same class of Disqualified Stock or Preferred Stock, the obligation to pay a premium in respect of Indebtedness arising in connection with the issuance of a notice of redemption or making of a mandatory offer to purchase such Indebtedness, and unrealized losses or charges in respect of Hedging Obligations (including those resulting from the application of SFAS 133), each will not be deemed to be an incurrence of Indebtedness for purposes of this Section 4.07; provided, in each such case, that the amount thereof as accrued shall be included as required in the calculation of the Consolidated Fixed Charge Coverage Ratio of the Company.

(f) For purposes of determining compliance with any U.S. dollar-denominated restriction on the incurrence of Indebtedness denominated in a foreign currency, the U.S. dollar-equivalent principal amount of such Indebtedness incurred pursuant thereto shall be calculated based on the relevant currency exchange rate in effect on the date that such Indebtedness was incurred, in the case of term Indebtedness, or first committed, in the case of revolving credit Indebtedness; provided that if such Indebtedness is incurred to refinance other Indebtedness denominated in a foreign currency, and such refinancing would cause the applicable U.S. dollar-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 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 and the Restricted Subsidiaries may incur pursuant to this Section 4.07 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

- 80 -

applicable to the currencies in which such Permitted Refinancing Indebtedness is denominated that is in effect on the date of such refinancing.

(g) For purposes of determining any particular amount of Indebtedness under this Section 4.07, (i) guarantees of, or obligations in respect of letters of credit relating to, Indebtedness otherwise included in the determination of such amount shall not also be included and (ii) if obligations in respect of letters of credit are incurred pursuant to a Credit Facility and are being treated as incurred pursuant to clause (1) of the definition of “Permitted Debt” and the letters of credit relate to other Indebtedness, then such other Indebtedness shall not be included. If Indebtedness is secured by a letter of credit that serves only to secure such Indebtedness, then the total amount deemed incurred shall be equal to the greater of (x) the principal of such Indebtedness and (y) the amount that may be drawn under such letter of credit.

(h) For purposes of the Indenture, no Indebtedness will be deemed to be subordinate or junior in right of payment to other Indebtedness solely by virtue of not having the benefit of a Lien on assets, or guarantee of a Person, that benefits the other Indebtedness or having the benefit of such a Lien or guarantee ranking subordinate or junior to a Lien or guarantee benefiting the other Indebtedness.

Section 4.08 Restricted Payments.

(a) The Company will not, and will not cause or permit any Restricted Subsidiary to, directly or indirectly:

(i) pay any dividend on, or make any distribution to holders of, any shares of the Company’s Capital Stock (other than dividends or distributions payable solely to the Company or a Restricted Subsidiary or in shares of the Company’s Qualified Capital Stock or in options, warrants or other rights to acquire shares of such Qualified Capital Stock);

(v) make any Investment in any Person (other than any Permitted Investments);

(any of the foregoing actions described in clauses (i) through (v) above, other than any such action that is a Permitted Payment (as defined below), collectively, “Restricted Payments”) (the amount of any such Restricted Payment, if other than cash, shall be the Fair Market Value of the assets proposed to be transferred) as determined by the Board of Directors of the Company, whose determination shall be conclusive and evidenced by a Board Resolution, unless

(1)    immediately after giving effect to such proposed Restricted Payment on a pro forma basis, no Default or Event of Default shall have occurred and be continuing;

(b)    in the case of the redesignation of an Unrestricted Subsidiary as a Restricted Subsidiary (as long as the designation of such Subsidiary as an Unrestricted Subsidiary was deemed a Restricted Payment), the Fair Market Value of the Company’s interest in such Subsidiary at the time of such redesignation; and

(F)    any amount which previously qualified as a Restricted Payment on account of any guarantee entered into by the Company or any Restricted Subsidiary; provided that such guarantee has not been called upon and the obligation arising under such guarantee no longer exists.

(b) Notwithstanding the foregoing, and in the case of clauses (2) through (9) and (11) through (14) below, so long as no Default or Event of Default is continuing or would arise therefrom, the foregoing provisions shall not prohibit the following actions (each of clauses (1) through (14), together with the transactions expressly excluded from clauses (i), (ii), (iii) and (iv) of paragraph (a) of this Section 4.08, being referred to as a “Permitted Payment”):

- 86 -

- 87 -

agreements, so long as, in the case of clause (b) or (c), the terms of any such amendment or replacement agreement or future agreement are, on the whole, no less advantageous to the Company or no less favorable to the Holders in any material respect than the agreement so amended or replaced or the similar agreement referred to in the preceding clause (a) or (b), respectively,

(7)in the case of (1) contracts for (A) drilling or other oil-field services or supplies, (B) the sale, storage, gathering or transport of Hydrocarbons or (C) the lease or rental of office or storage space or (2) other operation-type contracts, any such contracts that are entered into in the ordinary course of business on terms substantially similar to those contained in similar contracts entered into by the Company or any Restricted Subsidiary and third parties or, if none of the Company nor any Restricted Subsidiary has entered into a similar contract with a third party, on terms no less favorable than those available from third parties on an arm’s-length basis, as determined (i) in the case of contracts involving aggregate value of $50.0 million or less, by the Board of Directors of the Company or the senior management of the Company or (ii) in the case of contracts involving aggregate value in excess of $50.0 million, by the Disinterested Directors of the Board of Directors of the Company,

Section 4.10 Liens.

(a) The Company will not, and will not cause or permit any Restricted Subsidiary to, directly or indirectly, create or incur, in order to secure any Indebtedness, any Lien of any kind, other than Permitted Liens, upon any property or assets (including any intercompany notes) of the Company or any Restricted Subsidiary owned on the Issue Date or acquired after the Issue Date, or assign or convey, in order to secure any Indebtedness, any right to receive any income or profits therefrom, other than Permitted Liens, unless the Notes (or a Guarantee in the case of Liens of a Guarantor) are directly secured equally and ratably with (or, in the case of Subordinated Indebtedness, prior or senior thereto, with the same relative priority as the Notes shall have with respect to such Subordinated Indebtedness) the Indebtedness for so long as such Indebtedness is secured by such Lien.

(b) Notwithstanding the foregoing, any Lien securing the Notes or a Guarantee granted pursuant to Section 4.10(a) shall be automatically and unconditionally released and discharged upon: (i) the release of all other Liens that resulted in the grant of such Lien to secure the Notes or Guarantees pursuant to Section 4.10(a), (ii) any sale, exchange or transfer to any Person not an Affiliate of the Company of the property or assets secured by such Lien, (iii) any sale, exchange or transfer to any Person not an Affiliate of the Company of all of the Capital Stock held by the Company or any Restricted Subsidiary in, or all or substantially all the assets of, any Restricted Subsidiary creating such Lien, or (iv) if such Lien secures a Guarantee, the release of such Guarantee in accordance with this Supplemental Indenture.

Section 4.11 Asset Sales.

(a) The Company will not, and will not permit any Restricted Subsidiary to, consummate any Asset Sale unless (i) the Company or such Restricted Subsidiary, as the case may be, receives consideration at the time of such Asset Sale at least equal to the Fair Market Value of the assets and property subject to such Asset Sale (such Fair Market Value to be determined on the date of contractually agreeing to effect such Asset Sale) and (ii) (A) at least 75% of the consideration paid to the Company or such Restricted Subsidiary from such Asset Sale and all other Asset Sales since the Issue Date, on a cumulative basis, is in the form of cash, Cash Equivalents, Liquid Securities, Exchanged Properties (including pursuant to Asset Swaps) or the assumption by acquiring Person of Indebtedness or other liabilities of the Company or a Restricted Subsidiary (other than liabilities of the Company or a Restricted Subsidiary that are by their terms subordinated to the Notes) as a result of which the Company and the remaining Restricted Subsidiaries are no longer liable for such liabilities (or in lieu of such absence of liability, the acquiring Person or its parent company agrees to indemnify and hold the Company or such Restricted Subsidiary harmless from and against any loss, liability or cost in respect of such assumed liabilities accompanied by the posting of a letter of credit (issued by a commercial bank that has an Investment Grade Rating) in favor of the Company or such Restricted Subsidiary for the full amount of such liabilities and for so long as such liabilities remain outstanding unless such indemnifying party (or its long term debt securities) shall have an Investment Grade Rating (with no indication of a negative outlook or credit watch with negative implications, in any case, that contemplates such indemnifying party (or its long term debt securities) failing to have an Investment Grade Rating) at the time the indemnity is entered into) (“Permitted Consideration”) or (B) the Fair

- 89 -

Market Value of all forms of such consideration other than Permitted Consideration since the Issue Date does not exceed in the aggregate 5% of the Adjusted Consolidated Net Tangible Assets of the Company determined at the time such Asset Sale is made.

(b) During the 365 days after the receipt by the Company or a Restricted Subsidiary of Net Available Cash from an Asset Sale, such Net Available Cash may be applied by the Company or such Restricted Subsidiary, to the extent the Company or such Restricted Subsidiary elects (or is required by the terms of any Pari Passu Indebtedness of the Company or a Restricted Subsidiary), to:

(i) repay (or cash-collateralize) Indebtedness of the Company or any Restricted Subsidiary under any Credit Facility (excluding (i) any Subordinated Indebtedness and (ii) any Indebtedness owed to the Company or an Affiliate of the Company);

(ii) reinvest in Additional Assets (including by means of an Investment in Additional Assets by the Company or a Restricted Subsidiary with Net Available Cash received by the Company or another Restricted Subsidiary) or make capital expenditures in the Oil and Gas Business;

(iii) purchase Notes;

(iv) purchase or repay on a permanent basis other Indebtedness (excluding (i) any Subordinated Indebtedness and (ii) any Notes or other Indebtedness owed to the Company or an Affiliate of the Company); provided that the Company shall equally and ratably redeem or purchase Notes as described under Section 3.07, through open market purchases (to the extent such purchases are at or above 100% of the principal amount thereof) or by making an offer (in accordance with the procedures set forth below for a Prepayment Offer) to all Holders to purchase the Notes at 100% of the principal amount thereof, plus the amount of accrued but unpaid interest, if any, on the amount of Notes that would otherwise be prepaid; or

(v) make any combination of payment, repayment, investment or reinvestment permitted by the foregoing clauses (i) through (iv).

The requirement of clause (b)(2) above shall be deemed to be satisfied if an agreement (including a lease, whether a capital lease or an operating lease) committing to make the acquisitions or investment referred to therein is entered into by the Company or any Restricted Subsidiary within the time period specified in this Section 4.11(b) and such Net Available Cash is subsequently applied in accordance with such agreement within six months following such agreement.

Pending the final application of any such Net Available Cash, the Company may temporarily reduce Indebtedness under any Credit Facility or otherwise expend or invest such Net Available Cash in any manner that is not prohibited by this Supplemental Indenture.

(c) Any Net Available Cash from an Asset Sale not applied in accordance with Section 4.11(b) above within 365 days from the date of such Asset Sale shall constitute

- 90 -

“Excess Proceeds.” When the aggregate amount of Excess Proceeds exceeds $25.0 million, the Company will be required to make an offer to purchase Notes having an aggregate principal amount equal to the aggregate amount of Excess Proceeds (the “Prepayment Offer”) at a purchase price (the “Prepayment Offer Price”) equal to 100% of the principal amount of such Notes plus accrued and unpaid interest, if any, to the Asset Sale Purchase Date (as defined in Section 4.11(b)) (subject to the rights of Holders of record on relevant record dates to receive interest due on an interest payment date) in accordance with the procedures (including prorating in the event of over subscription) set forth in this Supplemental Indenture, but, if the terms of any Pari Passu Indebtedness require that a Pari Passu Offer be made contemporaneously with the Prepayment Offer, then the Excess Proceeds shall be prorated between the Prepayment Offer and such Pari Passu Offer in accordance with the aggregate outstanding principal amounts of the Notes and such Pari Passu Indebtedness (based on principal amounts of Notes and Pari Passu Indebtedness (or, in the case of Pari Passu Indebtedness issued with significant original issue discount, based on the accreted value thereof) tendered), and the aggregate principal amount of Notes to be purchased pursuant to the Prepayment Offer shall be reduced accordingly. If the aggregate principal amount of Notes tendered by Holders thereof exceeds the amount of Excess Proceeds available for purchase of Notes, then such amount of Excess Proceeds will be allocated among the Notes tendered and the Trustee will select the Notes to be purchased in accordance with this Supplemental Indenture on a pro rata basis (or, in the case of Global Notes, on as nearly a pro rata basis as is practicable, subject to the procedures of DTC or any other Depositary), by lot or in accordance with any other method the Trustee considers fair and reasonable and in minimum principal amount of $2,000 and integral multiples of $1,000 in excess of $2,000. To the extent that any portion of the amount of Excess Proceeds remains after compliance with this Section 4.11(c) and provided that all Holders of Notes have been given the opportunity to tender their Notes for purchase as described in Section 4.11(d) in accordance with this Supplemental Indenture, the Company or the Restricted Subsidiaries may use such remaining amount for purposes permitted by this Supplemental Indenture and the amount of Excess Proceeds will be reset to zero. The Company may satisfy the foregoing obligation with respect to any Excess Proceeds by making a Prepayment Offer prior to the expiration of the relevant 365 day period or with respect to Excess Proceeds of $25.0 million or less.

(d) Within 30 days after the 365th day following the date of an Asset Sale, the Company shall, if it is obligated to make a Prepayment Offer pursuant to Section 4.11(c), send a written Prepayment Offer notice, by first-class mail or otherwise in accordance with the procedures of DTC, to the Holders of the Notes (the “Prepayment Offer Notice”), with a copy to the Trustee, accompanied by such information regarding the Company and its Subsidiaries as the Company believes will enable such Holders of the Notes to make an informed decision with respect to the Prepayment Offer. The Prepayment Offer Notice will state, among other things:

(i) that the Company is offering to purchase Notes pursuant to the provisions of this Supplemental Indenture;

- 91 -

(ii) that any Note (or any portion thereof) accepted for payment (and duly paid on the Asset Sale Purchase Date) pursuant to the Prepayment Offer shall cease to accrue interest on the Asset Sale Purchase Date;

(iii) that any Notes (or portions thereof) not properly tendered will continue to accrue interest;

(iv) the purchase price and purchase date, which shall be, subject to any contrary requirements of applicable law, no less than 30 days nor more than 60 days after the date the Prepayment Offer Notice is mailed (the “Asset Sale Purchase Date”);

(v) the amount of Excess Proceeds available to purchase Notes;

(vi) a description of the procedure which Holders of Notes must follow in order to tender their Notes and the procedures that Holders of Notes must follow in order to withdraw an election to tender their Notes for payment; and

(vii) all other instructions and materials necessary to enable Holders to tender Notes pursuant to the Prepayment Offer.

If any of the Notes subject to a Prepayment Offer is in the form of a Global Note, then the Company shall modify such notice to the extent necessary to accord with the procedures of the Depositary applicable to repurchases.

(e) The Company will comply, to the extent applicable, with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws or regulations thereunder to the extent such laws and regulations are applicable in connection with the purchase of Notes as described above. To the extent that the provisions of any securities laws or regulations conflict with the provisions relating to the Prepayment Offer, the Company shall comply with the applicable securities laws and regulations and shall not be deemed to have breached its obligations under this Section 4.11 by virtue thereof.

(f) Holders electing to have Notes purchased hereunder will be required to surrender such Notes at the address specified in the notice prior to the close of business on the third Business Day prior to the Asset Sale Purchase Date. Holders will be entitled to withdraw their election to have their Notes purchased pursuant to this Section 4.11 if the Company receives, not later than one Business Day prior to the Asset Sale Purchase Date, a telegram, telex, facsimile transmission or letter specifying, as applicable:

(i) the name of the Holder,

(ii) the certificate number of the Note in respect of which such notice of withdrawal is being submitted,

(iii) the principal amount of the Note (which shall be $2,000 or whole multiples of $1,000 in excess thereof) delivered for purchase by the Holder as to which his election is to be withdrawn,

- 92 -

(iv) a statement that such Holder is withdrawing his election to have such principal amount of such Note purchased, and

(v) the principal amount, if any, of such Note (which shall be $2,000 or whole multiples of $1,000 in excess thereof) that remains subject to the original Prepayment Offer Notice and that has been or will be delivered for purchase by the Company.

(g) The Company shall (i) not later than the Asset Sale Purchase Date accept for payment Notes or portions thereof tendered pursuant to the Prepayment Offer, (ii) not later than 12:30 p.m. (New York City time) on the Asset Sale Purchase Date deposit with the Trustee or with a Paying Agent an amount of money in same day funds sufficient to pay the aggregate Prepayment Offer Price, as the case may be, of all the Notes or portions thereof which are to be purchased on that date and (iii) not later than 12:30 p.m. (New York City time) on the Asset Sale Purchase Date, as the case may be, deliver to the Paying Agent an Officers’ Certificate stating the Notes or portions thereof accepted for payment by the Company. The Company shall publicly announce the results of the Prepayment Offer, as the case may be, on or as soon as practicable after the Asset Sale Purchase Date.

(h) Upon receipt by the Company of the proper tender of any Note (or portion thereof) accepted for purchase pursuant to Section 4.11(c), the Holder of the Note (or portion thereof) accepted for purchase pursuant to Section 4.11(c) in respect of which such proper tender was made and which has so been accepted for purchase shall (unless the tender of such Note (or portion thereof) accepted for purchase pursuant to Section 4.11(c) is properly withdrawn at least one Business Day prior to the Asset Sale Purchase Date) thereafter be entitled to receive solely the Prepayment Offer Price with respect to such Note (or portion thereof) accepted for purchase pursuant to Section 4.11(c). Notes to be purchased shall, on the Asset Sale Purchase Date, become due and payable at the Prepayment Offer Price and from and after such date (unless the Company shall default in the payment of the Prepayment Offer Price) such Notes shall cease to bear interest. Such Prepayment Offer Price shall be paid to such Holder promptly following the later of the Asset Sale Purchase Date and the time of delivery of such Note to the relevant Paying Agent at the office of such Paying Agent by the Holder thereof in the manner required. Upon surrender of any such Note for purchase in accordance with the foregoing provisions, such Note shall be paid by the Company at the Prepayment Offer Price; provided, however, that installments of interest whose Stated Maturity is on or prior to the Asset Sale Purchase Date shall be payable to the Person in whose name the Notes are registered as such as of the close of business on the relevant record dates according to the terms and the provisions of Section 1.07. If any Note tendered for purchase shall not be so paid upon surrender thereof by deposit of funds with the Trustee or a Paying Agent in accordance with paragraph (g) of this Section 4.11, the principal thereof (and premium, if any, thereon) shall, until paid, bear interest from the Asset Sale Purchase Date at the rate borne by such Note. Any Note that is to be purchased only in part shall be surrendered to a Paying Agent at the office of such Paying Agent (with, if the Company, the Registrar or the Trustee so requires, due endorsement by, or a written instrument of transfer in form satisfactory to the Company and the Registrar or 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, one or more new Notes of any authorized denomination as requested by such

- 93 -

Holder in an aggregate principal amount equal to, and in exchange for, the portion of the principal amount of the Note so surrendered that is not purchased. For all purposes of this Section 4.11, unless the context otherwise requires, all provisions relating to the purchase of Notes shall relate, in the case of any Notes purchased or to be purchased only in part, to the portion of the principal amount of such Notes which has been or is to be purchased. The Paying Agent (at the Company’s expense) shall promptly mail or deliver to the Holder thereof any Note or portion thereof not to be so purchased.

Section 4.12 Issuances of Guarantees by Restricted Subsidiaries.

(a) The Company will provide to the Trustee, on or prior to the 30th day after the date that any Restricted Subsidiary (which is not a Guarantor) becomes a guarantor or obligor in respect of any Indebtedness of the Company or any Restricted Subsidiary in an aggregate principal amount exceeding $5.0 million, a supplemental indenture to the Indenture substantially in the form of Exhibit D hereto, executed by such Restricted Subsidiary, providing for a full and unconditional guarantee on a senior unsecured basis by such Restricted Subsidiary’s obligations under the Notes and the Indenture to the same extent as that set forth in the Indenture, subject to such Restricted Subsidiary ceasing to be a Guarantor when its Guarantee is released in accordance with the terms of the Indenture.

(b) Notwithstanding paragraph (a) of this Section 4.12, (i) no Foreign Subsidiary shall be required to execute any such supplemental indenture unless such Foreign Subsidiary has guaranteed (or is otherwise an obligor of) other Indebtedness (including Indebtedness under a Credit Facility) of the Company or a Restricted Subsidiary that is not a Foreign Subsidiary in an aggregate principal amount exceeding $5.0 million, and (ii) no Restricted Subsidiary shall be required to execute any such supplemental indenture if the Consolidated Net Worth of such Restricted Subsidiary, together with the Consolidated Net Worth of all other Non-Guarantor Restricted Subsidiaries, as of such date, does not exceed in the aggregate $5.0 million. To the extent the collective Consolidated Net Worth of the Company’s Non-Guarantor Restricted Subsidiaries, as of the date of the creation of, acquisition of or Investment in a Non-Guarantor Restricted Subsidiary, exceeds $5.0 million, the Company shall cause, within 30 days after such date, one or more of such Non-Guarantor Restricted Subsidiaries to similarly execute and deliver to the Trustee a supplemental indenture to the Indenture substantially in the form of Exhibit D hereto providing for a full and unconditional guarantee on a senior unsecured basis by such Restricted Subsidiary of the Company’s obligations under the Notes and the Indenture to the same extent as that set forth as to the Initial Guarantors in Article Nine, such that the collective Consolidated Net Worth of all remaining Non-Guarantor Restricted Subsidiaries does not exceed $5.0 million.

Section 4.13 Dividend and Other Payment Restrictions Affecting Restricted Subsidiaries.

(a) The Company will not, and will not cause or permit any Restricted Subsidiary to, directly or indirectly, create or otherwise cause to come into existence or become effective any consensual encumbrance or restriction on the ability of any Restricted Subsidiary to:

- 94 -

(1)    pay dividends or make any other distribution on its Capital Stock to the Company or any Restricted Subsidiary (it being understood that the priority of any Preferred Stock in receiving dividends or liquidating distributions prior to dividends or liquidating distributions being paid on common stock shall not be deemed a restriction on the ability to pay dividends or make distributions on Capital Stock),

(2)     pay any Indebtedness owed to the Company or any other Restricted Subsidiary (it being understood that the subordination of Indebtedness owed to the Company or any Restricted Subsidiary to other Indebtedness owed by the Company or any Restricted Subsidiary shall not be deemed a restriction on the ability to pay such Indebtedness),

(3)    make loans or advances to the Company or any other Restricted Subsidiary (it being understood that the subordination of loans or advances made by the Company or any Restricted Subsidiary to other Indebtedness incurred by the Company or any Restricted Subsidiary shall not be deemed a restriction on the ability to make loans or advances), or

(4)     transfer any of its properties or assets to the Company or any other Restricted Subsidiary.

(b) However, Section 4.13(a) will not prohibit any encumbrance or restriction created, existing or becoming effective under or by reason of:

(1)     any agreement (including the Senior Credit Agreement, the indenture governing the Existing Senior Notes and this Supplemental Indenture) in effect on the Issue Date;

(2)     any agreement or instrument with respect to a Restricted Subsidiary that is not a Restricted Subsidiary on the Issue Date, in existence at the time such Person becomes a Restricted Subsidiary and not incurred in connection with, or in contemplation of, such Person becoming a Restricted Subsidiary; provided that such encumbrances and restrictions are not applicable to, or to the properties or assets of, the Company or any Restricted Subsidiary other than such Subsidiary which is becoming a Restricted Subsidiary;

(3)     any agreement or instrument governing any Acquired Debt or other agreement of any entity merged into or consolidated with, or the assets of which are acquired by, the Company or any Restricted Subsidiary, so long as such encumbrance or restriction (A) was not entered into in contemplation of the acquisition, merger or consolidation transaction, and (B) is not applicable to any Person, or the properties or assets of any Person, other than the Person, or the property or assets or subsidiaries of the Person, so acquired, so long as the agreement containing such restriction does not violate any other provision of the Indenture;

(4)     any applicable law or any requirement of any regulatory body;

(5)     customary restrictions and conditions contained in the security documents evidencing any Liens securing obligations or Indebtedness or agreements relating to Capital Lease Obligations (provided that such Liens are otherwise permitted to be incurred under the provisions of Section 4.10 and such restrictions and conditions are not created for the purpose of

- 95 -

(1)    no Default or Event of Default shall have occurred and be continuing at the time of or after giving effect to such Designation;

(2)    (x) the Company would be permitted to make an Investment at the time of Designation (assuming the effectiveness of such Designation) pursuant to paragraph (a) of Section 4.08 or as a Permitted Payment or Permitted Investment in an amount (the “Designation Amount”) equal to the greater of (1) the net book value of the Company’s interest in such Subsidiary calculated in accordance with GAAP and (2) the Fair Market Value of the Company’s interest in such Subsidiary as determined in good faith by the Company’s Board of Directors, or (y) the Designation Amount is less than $1,000;

(5)    such Unrestricted Subsidiary is not a party to any agreement, contract, arrangement or understanding at such time with the Company or any Restricted Subsidiary unless the terms of any such agreement, contract, arrangement or understanding are no less favorable to the Company or such Restricted Subsidiary than those that might be obtained at the time from Persons who are not Affiliates of the Company or, in the event such condition is not satisfied, the value of such agreement, contract, arrangement or understanding to such Unrestricted Subsidiary shall be deemed a Restricted Payment.

(b) In the event of any such Designation, the Company shall be deemed, for all purposes of this Supplemental Indenture, to have made an Investment equal to the Designation Amount that, as designated by the Company, constitutes a Restricted Payment pursuant to paragraph (a) of Section 4.08 or a Permitted Payment or Permitted Investment.

- 98 -

Permitted Investments, Restricted Payments or Permitted Payments in Unrestricted Subsidiaries that are otherwise allowed under this Supplemental Indenture, or

Section 4.17 Offer to Repurchase upon a Change of Control.

(a) If a Change of Control occurs, unless the Company has given (or, if a Change of Control occurs prior to May 1, 2013, within 60 days thereafter will have given) notice of redemption of all the Notes as described in Section 3.07, each Holder will have the right to require that the Company purchase all or any part (in amounts of $2,000 or whole multiples of $1,000 in excess thereof) of such Holder’s Notes pursuant to the offer described below

- 99 -

(the “Change of Control Offer”). In the Change of Control Offer, the Company will offer to purchase all of the Notes, at a purchase price (the “Change of Control Purchase Price”) in cash in an amount equal to 101% of the principal amount of such Notes, plus accrued and unpaid interest, if any, to the date of purchase (the “Change of Control Purchase Date”) subject to the rights of Holders of record on relevant record dates to receive interest due on an interest payment date. Any Change of Control Offer that is made prior to the occurrence of a Change of Control may at the Company’s discretion be subject to one or more conditions precedent, including the occurrence of a Change of Control.

(b) Within 30 days after any Change of Control or, at the Company’s option, prior to such Change of Control but after it is publicly announced, unless the Company has given (or, if a Change of Control occurs prior to May 1, 2013, within 60 days thereafter will have given) notice of redemption of all the Notes as described in Section 3.07, the Company shall notify the Trustee and give written notice of the Change of Control to each Holder, by first-class mail, postage prepaid, at his address appearing in the Security Register or otherwise in accordance with the procedures of DTC. The notice (the “Change of Control Purchase Notice”) shall state, among other things:

(i) that a Change of Control has occurred or will occur, the date of such event and the circumstances and relevant facts regarding such Change of Control;

(ii) that any Notes (or any portion thereof) accepted for payment (and duly paid on the Change of Control Purchase Date) pursuant to the Change of Control Offer shall cease to accrue interest on the Change of Control Purchase Date;

(iii) that any Notes (or any portion thereof) not properly tendered will continue to accrue interest;

(iv) the Change of Control Purchase Price and the Change of Control Purchase Date, which shall be, subject to any contrary requirements of applicable law, no less than 30 days nor more than 60 days after the date the notice is mailed; provided that the Change of Control Purchase Date may not occur prior to the Change of Control;

(v) a description of the procedures that Holders of Notes are required to follow in order to tender their Notes and the procedures that Holders of Notes are required to follow in order to withdraw an election to tender their Notes for payment; and

(vi) all other instructions and materials necessary to enable Holders to tender Notes pursuant to the Change of Control Offer.

(c) Upon receipt by the Company of the proper tender of Notes, the Holder of the Note in respect of which such proper tender was made shall (unless the tender of such Note is

- 100 -

properly withdrawn at least one Business Day prior to the Change of Control Purchase Date) thereafter be entitled to receive solely the Change of Control Purchase Price with respect to such Notes. Notes to be purchased shall, on the Change of Control Purchase Date, become due and payable at the Change of Control Purchase Price, and from and after such date (unless the Company shall default in the payment of the Change of Control Purchase Price) such Notes shall cease to bear interest. Such Change of Control Purchase Price shall be paid to such Holder promptly following the later of the Change of Control Purchase Date and the time of delivery of such Note to the relevant Paying Agent at the office of such Paying Agent by the Holder thereof in the manner required. Upon surrender of any such Note for purchase in accordance with the foregoing provisions, such Note shall be paid by the Company at the Change of Control Purchase Price; provided, however, that installments of interest whose Stated Maturity is on or prior to the Change of Control Purchase Date shall be payable to the Holders of such Notes, registered as such as of the close of business on the relevant record dates according to the terms and the provisions of Section 1.07. If any Note tendered for purchase in accordance with the provisions of this Section 4.17 shall not be so paid upon surrender thereof, the principal thereof (and premium, if any, thereon) shall, until paid, bear interest from the Change of Control Purchase Date at the rate borne by such Note. Holders electing to have Notes purchased will be required to surrender such Notes to the Paying Agent at the address specified in the Change of Control Purchase Notice prior to the close of business on the third Business Day prior to the Change of Control Purchase Date. Any Note that is to be purchased only in part shall be surrendered to a Paying Agent at the office of such Paying Agent (with, if the Company, the Registrar or the Trustee so require, due endorsement by, or a written instrument of transfer in form satisfactory to the Company and the Registrar or the Trustee, as the case may be, 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, one or more new Notes of any authorized denomination as requested by such Holder in an aggregate principal amount equal to, and in exchange for, the portion of the principal amount of the Note so surrendered that is not purchased. For all purposes of this Section 4.17, unless the context otherwise requires, all provisions relating to the purchase of Notes shall relate, in the case of any Notes purchased or to be purchased only in part, to the portion of the principal amount of such Notes which has been or is to be purchased. The Paying Agent (at the Company’s expense) shall promptly mail or deliver to the Holder thereof any Note or portion thereof not to be so purchased.

(d) The Company shall (i) not later than the Change of Control Purchase Date, accept for payment Notes or portions thereof tendered pursuant to the Change of Control Offer, (ii) not later than 12:30 p.m. (New York City time) on the Change of Control Purchase Date, deposit with the Trustee or with a Paying Agent an amount of money in same day funds sufficient to pay the aggregate Change of Control Purchase Price of all the Notes or portions thereof that are to be purchased on that date and (iii) not later than 12:30 p.m. (New York City time) on the Change of Control Purchase Date, deliver to the Paying Agent an Officers’ Certificate stating the Notes or portions thereof accepted for payment by the Company. The Company shall publicly announce the results of the Change of Control Offer on or as soon as practicable after the Change of Control Purchase Date.

- 101 -

(1)     the name of the Holder;

(2)    the certificate number of the Note in respect of which such notice of withdrawal is being submitted;

(3)    the principal amount of the Note (which shall be $2,000 or whole multiples of $1,000 in excess thereof) delivered for purchase by the Holder as to which such notice of withdrawal is being submitted;

(4)    a statement that such Holder is withdrawing his election to have such principal amount of such Note purchased; and

(5)    the principal amount, if any, of such Note (which shall be $2,000 or whole multiples of $1,000 in excess thereof) that remains subject to the original Change of Control Purchase Notice and that has been or will be delivered for purchase by the Company.

(f) The Company shall comply, to the extent applicable, with the requirements of Rule 14e-1 under the Exchange Act, and any other securities laws or regulations thereunder to the extent such laws and regulations are applicable in connection with the purchase of the Notes as described above. To the extent that the provisions of any securities laws or regulations conflict with the provisions relating to the Change of Control Offer, the Company shall comply with the applicable securities laws and regulations and shall not be deemed to have breached its obligations under this Section 4.17 by virtue thereof.

(g) Notwithstanding the foregoing, the Company will not be required to make a Change of Control Offer (1) upon a Change of Control, if a third party makes the Change of Control Offer in the manner, at the times and otherwise in compliance with the requirements set forth in this Supplemental Indenture 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 or (2) if notice of redemption for 100% of the aggregate principal amount of the outstanding Notes has been (or, if a Change of Control occurs prior to May 1, 2013, within 60 days thereafter will have been) given pursuant to this Supplemental Indenture as described in Section 3.07, unless and until there is a default in payment of the applicable redemption price.

(h) In the event that upon consummation of a Change of Control Offer less than 10% of the aggregate principal amount of the Notes (including Additional Notes) that were originally issued are held by Holders other than the Company or Affiliates thereof, the Company will have the right, upon not less than 30 nor more than 60 days’ prior notice, given not more than 30 days following the purchase pursuant to the Change of Control Offer described above, to redeem all of the Notes that remain outstanding following such purchase at a redemption price equal to 101% of the aggregate principal amount of the Notes

- 102 -

redeemed plus accrued and unpaid interest, if any, thereon to the date of redemption, subject to the right of the Holders of record on relevant record dates to receive interest due on an interest payment date.

Section 4.18 Corporate Existence.

Subject to Article Five, the Company shall do or cause to be done all things necessary to preserve and keep in full force and effect its existence, rights (charter and statutory), licenses and franchises; provided, however, that the Company shall not be required to preserve any such right, license or franchise if it shall determine that the preservation thereof is no longer desirable in the conduct of the business of the Company.

Section 4.19 Covenant Suspension.

(a) If at any time (1) the Notes are rated at least Baa3 by Xxxxx’x and at least BBB- by S&P (or, if either such entity ceases to rate the Notes for reasons outside of the control of the Company, at least the equivalent investment grade credit rating from any other “nationally recognized statistical rating organization” within the meaning of Rule 15c3-1(c)(2)(vi)(F) under the Exchange Act selected by the Company as a replacement agency); and (2) at such time no Event of Default shall have occurred and be continuing then, beginning on that day and on each day thereafter (subject to the provisions of Section 4.19(c)) the following covenants (the “Suspended Covenants”) will be suspended and the Company and the Restricted Subsidiaries shall not be subject to (and shall not be required to comply with) the Suspended Covenants:

(i) Section 4.11;

(ii) Section 4.08;

(iii) Section 4.07;

(iv) Section 4.13;

(v) clauses (1) and (3) of Section 4.14;

(vi) clause (4) of Section 5.01(a);

(vii) Section 4.09;

(viii) Section 4.15; and

(ix) Section 4.12.

(b) During any period that the foregoing covenants have been suspended (each such period, a “Suspension Period”), the Company’s Board of Directors may not designate any of its Restricted Subsidiaries as Unrestricted Subsidiaries pursuant Section 4.15.

- 103 -

(c) Notwithstanding Section 4.19(a) and (b), if the rating assigned by either such Rating Agency should subsequently decline to below Baa3 or BBB-, respectively, the Suspended Covenants will be reinstituted on and as of the date of such rating decline (such date, a “Reversion Date”) and on the Reversion Date and each date thereafter (subject to the provisions of Section 4.19(a)) the Company and the Restricted Subsidiaries shall be subject to (and shall be required to comply with) the Suspended Covenants.

(d) For purposes of calculating the amount available to be made as Restricted Payments under Section 4.08(a)(v)3), calculations under that clause will be made with reference to the date of the Restricted Payment, as set forth in that clause. Accordingly (x) Restricted Payments made during the Suspension Period that would not otherwise be permitted pursuant to any of clauses (b)(1) through (b)(14) of Section 4.08 will reduce the amount available to be made as Restricted Payments under Section 4.08(a)(v)(3); provided, however, that the amount available to be made as a Restricted Payment shall not be reduced to below zero solely as a result of such Restricted Payments but may be reduced to below zero as a result of negative cumulative Consolidated Net Income during the Suspension Period for purposes of Section 4.08(a)(v)(3)(A) and (y) the items specified in clauses (a)(v)(3)(A) through (F) of Section 4.08 that occur during the Suspension Period will increase the amount available to be made as Restricted Payments under clause (a)(v)(3) of Section 4.08. For purposes of Section 4.11, on each Reversion Date, the unutilized Excess Proceeds will be reset to zero. No Default or Event of Default will be deemed to have occurred or exist on the Reversion Date (or thereafter) under any Suspended Covenant, solely as a result of, or as a result of the continued existence on or after the Reversion Date of facts and circumstances arising from, any actions taken by the Company or any Restricted Subsidiaries thereof, or events occurring, or performance on or after the Reversion Date of any obligations arising from transactions which occurred, during the Suspension Period.

Any reference in this Article Six or elsewhere in this Supplemental Indenture to “Event of Default” shall be deemed to refer to and include only the Events of Default with respect to the Notes specified in this Section 6.01, and the term “Default” as so used in this Supplemental Indenture shall have a correlative meaning.

Section 6.02 Acceleration.

(a) If an Event of Default (other than as specified in Section 6.01(8) or (9) above with respect to the Company) shall occur and be continuing with respect to this Supplemental Indenture, the Trustee or the Holders of not less than 25% in aggregate principal amount of the Notes then outstanding may declare all unpaid principal of, premium, if any, and accrued interest on all Notes to be due and payable immediately, by a notice in writing to the Company (and to the Trustee if given by the Holders of the Notes) and upon any such declaration, such principal, premium, if any, and interest shall become due and payable immediately. If an Event of Default specified in Section 6.01(8) or (9) above with respect to the Company occurs and is continuing, then all the Notes shall ipso facto become due and payable immediately in an amount equal to the principal amount of the Notes, together with accrued and unpaid interest, if any, to the date the Notes become due and payable, without any declaration or other act on the part of the Trustee or any Holder of Notes. Thereupon, the Trustee may, at its discretion, proceed to protect and enforce the rights of the Holders of Notes by appropriate judicial proceedings.

(b) After a declaration of acceleration, but before a judgment or decree for payment of the money due has been obtained by the Trustee, the Holders of a majority in aggregate principal amount of Notes outstanding by written notice to the Company and the Trustee, may rescind and annul such declaration and its consequences if:

(1)    the Company has paid or deposited with the Trustee a sum sufficient to pay (A) all sums paid or advanced by the Trustee under this Supplemental Indenture and the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, (B) all overdue interest on all Notes then outstanding, (C) the principal of, and premium, if any, on any Notes then outstanding which have become due otherwise than by such declaration of acceleration and interest thereon at the rate borne

- 109 -

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

(2)    the rescission would not conflict with any judgment or decree of a court of competent jurisdiction; and

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

No such rescission shall affect any subsequent default or impair any right consequent thereon.

(c) If an Event of Default specified in Section 6.01(5) above shall have occurred and be continuing, such Event of Default and any consequential acceleration shall be automatically rescinded if (i) the Indebtedness that is the subject of such Event of Default shall have been repaid or (ii) if the default relating to such Indebtedness is waived or cured and if such Indebtedness shall have been accelerated, the Holders thereof have rescinded their declaration of acceleration in respect of such Indebtedness.

Section 6.03 Other Remedies.

(a) If an Event of Default occurs and is continuing, the Trustee may pursue any available remedy to collect the payment of principal, premium, if any, or interest on the Notes or to enforce the performance of any provision of the Notes, the Base Indenture (as it relates to the Notes) or this Supplemental Indenture.

(b) 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 of a Note in exercising any right or remedy accruing upon and during the continuance of 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 a majority in aggregate principal amount of the Notes outstanding may on behalf of the Holders of all outstanding Notes waive any past Default or Event of Default under this Supplemental Indenture or any other provision of the Indenture with respect to the Notes and its consequences, except a Default or Event of Default (1) in the payment of the principal of, premium, if any, or interest on any Note (which may only be waived with the consent of each Holder of Notes affected) or (2) in respect of a covenant or provision which under Section 8.02 cannot be modified or amended without the consent of the Holder of each Note affected by such modification or amendment. This Section 6.04 shall be in lieu of Section 316(a)(1)(B) of the TIA and such Section 316(a)(1)(B) of the TIA is hereby expressly excluded from this Supplemental Indenture and the Notes, as permitted by the TIA. Upon any such waiver, such Default shall cease to exist and any Event of Default arising therefrom shall be

- 110 -

deemed to have been cured for every purpose of this Supplemental 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.

Subject to Section 1.13, Holders of a majority in principal amount of the then outstanding Notes may direct the time, method and place of conducting any proceeding for exercising any remedy available to the Trustee or exercising any trust or power conferred on it. However, the Trustee may refuse to follow any direction that conflicts with law, the Base Indenture (as it relates to the Notes) or this Supplemental Indenture or that the Trustee determines may be unduly prejudicial to the rights of other Holders of Notes or that may subject the Trustee to personal liability; provided, however, that the Trustee may take any other action deemed proper by the Trustee that is not inconsistent with such direction. The Trustee may withhold from Holders of the Notes notice of any continuing Default or Event of Default (except a Default or Event of Default relating to the payment of principal or interest) if it determines that withholding notice is in their interest.

Section 6.06 Limitation on Suits.

(a) A Holder has a right to institute any proceeding with respect to the Base Indenture (as it relates to the Notes), this Supplemental Indenture or the Notes or any Guarantees, only if:

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

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

(3) such Holder of a Note or Holders of Notes offer and, if requested, provide to the Trustee reasonable indemnity against any loss, liability or expense that might be incurred by it in connection with the request or direction;

(4) the Trustee does not comply with the request within 60 days after receipt of the request and the offer and, if requested, the provision of indemnity; and

(5) during such 60-day period the Holders of a majority in principal amount of the then outstanding Notes have not waived such Event of Default or otherwise given the Trustee a direction inconsistent with the written request.

(b) A Holder of a Note may not use the Indenture to prejudice the rights of another Holder of a Note or to obtain a preference or priority over another Holder of a Note.

Section 6.07 Rights of Holders of Notes to Receive Payment.

Notwithstanding any other provision of the Indenture, the right of any Holder of a Note to receive payment of principal, premium, if any, or interest on such Note, on or after the respective due dates expressed in such Note (including in connection with an offer to purchase),

- 111 -

or to bring suit for the enforcement of any such payment on or after such respective dates, shall not be impaired or affected without the consent of such Holder.

Section 6.08 Collection Suit by Trustee.

If an Event of Default specified in Section 6.01(1) or (2) above 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 for the whole amount of overdue principal of, premium, if any, interest remaining unpaid on the Notes and interest on overdue principal and premium, if any, and, to the extent lawful, interest and such further amount as shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel and any other amounts provided for in Section 607 of the Base Indenture.

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 of the Notes allowed in any judicial proceedings relative to the Company or any Guarantor (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 securities or 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 607 of the Base Indenture. 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 607 of the Base Indenture 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 that 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, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding.

Section 6.10 Priorities.

(a) If the Trustee collects any money or other property pursuant to this Article Six, it shall pay out the money and other property in the following order:

First: to the Trustee, its agents and attorneys for amounts due under Section 607 of the Base Indenture, including payment of all compensation, expense and liabilities incurred, and all advances made, by the Trustee and the costs and expenses of collection;

- 112 -

Second: to Holders of Notes for amounts due and unpaid on the Notes for principal, premium, if any, 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.

(b) The Trustee may fix a record date and payment date for any payment to Holders of Notes pursuant to this Section 6.10.

Section 6.11 Undertaking for Costs.

In any suit for the enforcement of any right or remedy under the Base Indenture (as it relates to the Notes) or this Supplemental 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 of a Note pursuant to Section 6.07, or a suit by Holders of more than ten percent in principal amount of the then outstanding Notes.

Article Seven

Defeasance and Covenant Defeasance

Article XIII of the Base Indenture shall not apply to the Notes, except as, and to the extent, described in this Article Seven.

Section 7.01 Option to Effect Legal Defeasance or Covenant Defeasance.

The Company may, at its option and at any time, elect to have either Section 7.02 or Section 7.03 be applied to all outstanding Notes upon compliance with the conditions set forth below in this Article Seven.

Section 7.02 Legal Defeasance and Discharge.

Upon the Company’s exercise of the option applicable to this Section 7.02, the Company shall, subject to the satisfaction of the conditions set forth in Section 7.04, be deemed to have been discharged from its obligations with respect to all outstanding Notes and all obligations of the Guarantors shall be deemed to have been discharged with respect to their obligations under the Guarantees on the date the conditions set forth below are satisfied (hereinafter, “Legal Defeasance”). For this purpose, Legal Defeasance means that the Company and the Guarantors shall be deemed to have paid and discharged the entire Indebtedness represented by the outstanding Notes and Guarantees, respectively, which shall thereafter be deemed to be “outstanding” only for the purposes of Section 7.05 and the other Sections of this Supplemental Indenture referred to in clauses (a) and (b) below, and to have satisfied all of their other obligations under such Notes and this Supplemental Indenture (and the Trustee, on demand

- 113 -

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: (a) the rights of the Holders of outstanding Notes to receive solely from Funds in Trust (as defined in Section 7.04 and as more fully set forth in such Section) payments in respect of the principal of, premium, if any, and interest on such Notes when such payments are due, (b) subject to the preceding clause (a), the Company’s obligations with respect to such Notes under Article One and Section 4.02, (c) the rights, powers, trusts, duties and immunities of the Trustee under the Indenture and (d) this Article Seven. Subject to compliance with this Article Seven, the Company may exercise its option under this Section 7.02 notwithstanding the prior exercise of its option under Section 7.03.

Section 7.03 Covenant Defeasance.

Upon the Company’s exercise under Section 7.01 of the option applicable to this Section 7.03, subject to the satisfaction of the conditions set forth in Section 7.04, (i) the Company shall be released from its obligations, and each Guarantor shall be released from its obligations, in each case, under the covenants contained in Article Four and Section 5.01 (except for the obligations of the Company or a Guarantor under paragraph (a) of Section 5.01 solely insofar as they relate to the Company, except as described further in clause (ii) of this sentence), and (ii) the limitations described in clause (4) of paragraph (a) of Section 5.01 with respect to the outstanding Notes shall no longer apply, on and after the date the conditions set forth in Section 7.04 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 the Holders (and the consequences of any thereof) in connection with such covenants, but shall continue to be deemed “outstanding” for all other purposes hereunder (it being understood that such Notes shall not be deemed outstanding for accounting purposes). For this purpose, Covenant Defeasance means that, with respect to the outstanding Notes, the Company and each Restricted Subsidiary 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, but, except as specified above, the remainder of this Supplemental Indenture and such Notes shall be unaffected thereby. In addition, upon the Company’s exercise under Section 7.01 of the option applicable to this Section 7.03, subject to the satisfaction of the conditions set forth in Section 7.04, Section 6.01(3) through (7) shall not constitute Events of Default.

Section 7.04 Conditions to Legal Defeasance or Covenant Defeasance.

The following shall be the conditions to the application of either Section 7.02 or Section 7.03 to the outstanding Notes:

(a) the Company shall have irrevocably deposited or caused to be deposited with the Trustee, in trust, specifically pledged as security for, and dedicated solely to, the benefit of the Holders of the Notes cash in United States dollars, U.S. Government Obligations, or a combination thereof (“Funds in Trust”), in such amounts as, in the aggregate, will be sufficient, in the opinion of a nationally recognized firm of independent public accountants or

- 114 -

a nationally recognized investment banking firm, to pay and discharge the principal of, premium, if any, and interest on the outstanding Notes on the Stated Maturity (or on any date after May 27, 2012 (such date being referred to as the “Defeasance Redemption Date”), if at or prior to electing either Legal Defeasance or Covenant Defeasance, the Company has delivered to the Trustee an irrevocable notice to redeem all of the outstanding Notes on the Defeasance Redemption Date);

(c) in the case of Covenant Defeasance, the Company shall have delivered to the Trustee an opinion of independent counsel in the United States to the effect that the Holders and beneficial owners of the outstanding Notes will not recognize income, gain or loss for federal income tax purposes as a result of such Covenant Defeasance and will be subject to federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Covenant Defeasance had not occurred;

(d) no Default or Event of Default shall have occurred and be continuing on the date of such deposit (other than a Default or Event of Default resulting from the incurrence of Indebtedness or other borrowing of funds, or the grant of Liens securing such Indebtedness or other borrowing, all or a portion of which are to be applied to such deposit);

(e) such Legal Defeasance or Covenant Defeasance shall not result in a breach or violation of, or constitute a Default under, any material agreement or instrument to which the Company, any Guarantor or any Restricted Subsidiary is a party or by which the Company, any Guarantor or any Restricted Subsidiary is bound (other than this Supplemental Indenture);

(f) the Company shall have delivered to the Trustee an Officers’ Certificate stating that the deposit was not made by the Company with the intent of preferring the Holders of the Notes or any Guarantee over the other creditors of the Company or any Guarantor with the intent of defeating, hindering, delaying or defrauding creditors of the Company or any Guarantor; and

(g) the Company will have delivered to the Trustee an Officers’ Certificate and an opinion of independent counsel, each stating that all conditions precedent relating to either the Legal Defeasance or the Covenant Defeasance, as the case may be, have been complied with.

- 115 -

Section 7.05 Deposited Money and U.S. Government Obligations to Be Held in Trust; Other Miscellaneous Provisions.

(a) Subject to Section 7.06, all money and non-callable U.S. Government Obligations (including the proceeds thereof) deposited with the Trustee (or other qualifying trustee, collectively for purposes of this Section 7.05, the “Trustee”) pursuant to Section 7.04 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 Supplemental 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, premium and interest, but such money need not be segregated from other funds except to the extent required by law.

(b) The Company shall pay and indemnify the Trustee against any tax, fee or other charge imposed on or assessed against the cash or non-callable U.S. Government Obligations deposited pursuant to Section 7.04 or the principal and interest received in respect thereof other than any such tax, fee or other charge which by law is for the account of the Holders of the outstanding Notes.

(c) Anything in this Article Seven 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 non-callable U.S. Government Obligations held by it as provided in Section 7.04 which, in the opinion of a nationally recognized firm of independent public accountants, investment bank, or appraisal firm expressed in a written certification thereof delivered to the Trustee (which may be the opinion delivered under Section 7.04(a)), are in excess of the amount thereof that would then be required to be deposited to effect an equivalent Legal Defeasance or Covenant Defeasance.

Section 7.06 Repayment to the 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, and premium, if any, or interest has become due and payable shall be paid to the Company upon its request or (if then held by the Company) shall be discharged from such trust; and the Holder of such Note shall thereafter look only to the Company for payment thereof, and all liability of the Trustee or such Paying Agent with respect to such trust money, and all liability of the Company as trustee thereof, shall thereupon cease; provided, however, that the Trustee or such Paying Agent, before being required to make any such repayment, may, at the expense of the Company, cause to be published once, in The New York Times or 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 shall be repaid to the Company.

Section 7.07 Reinstatement.

- 116 -

If the Trustee or Paying Agent is unable to apply any United States dollars or non-callable U.S. Government Obligations in accordance with Section 7.02 or Section 7.03, as the case may be, by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, then the Company’s obligations to make the related payments under this Supplemental Indenture and the Notes shall be revived and reinstated as though no deposit had occurred pursuant to Section 7.02 or Section 7.03 until such time as the Trustee or Paying Agent is permitted to apply all such money in accordance with Section 7.02 or Section 7.03, as the case may be; provided, however, that, if the Company make 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 Holders of such Notes to receive such payment from the money held by the Trustee or Paying Agent.

(1) change the Stated Maturity of the principal of, or any installment of interest on, or change to an earlier date any redemption date of, or waive a default in the payment of the principal of, premium, if any, or interest on, any such Note or reduce the principal amount thereof or the rate of interest thereon or any premium payable upon the redemption thereof, or change the coin or currency in which the principal of any such Note or any premium or the interest thereon is payable, or impair the right to institute suit for the enforcement of any such payment after the Stated Maturity thereof (or, in the case of redemption, on or after the redemption date);

(2) amend, change or modify, (a) after the obligation of the Company to make a Prepayment Offer with respect to an Asset Sale has arisen, in accordance with Section 4.11, the obligation of the Company, to make such Prepayment Offer or (b) the obligation of the Company, after the occurrence of a Change of Control, to make a Change of Control Offer in accordance with Section 4.17;

(3) reduce the percentage in principal amount of such outstanding Notes, the consent of whose Holders is required for any such amendment of the Indenture (including this Supplemental Indenture), or the consent of whose Holders is required for any waiver or compliance with certain provisions of this Supplemental Indenture;

(4) modify any of the provisions of the Indenture requiring the consent of Holders or relating to the waiver by Holders of past defaults or relating to the waiver by Holders of certain covenants, except to increase the percentage of such outstanding Notes required for such actions or to provide that certain other provisions of the Indenture cannot be modified or waived without the consent of the Holder of each such Note affected thereby;

(5) voluntarily release, other than in accordance with this Supplemental Indenture, the Guarantee of any Guarantor with respect to the Notes; or

(6) amend or modify any of the provisions of the Indenture in any manner which subordinates the Notes issued hereunder in right of payment to any other Indebtedness of the Company or which subordinates any Guarantee with respect to the Notes in right of payment to any other Indebtedness of the Guarantor issuing any such Guarantee.

- 119 -

(b) Upon the request of the Company accompanied by a resolution of its Board of Directors authorizing the execution of any such amended or supplemental indenture, and upon the filing with the Trustee of evidence reasonably satisfactory to the Trustee of the consent of the Holders of Notes as aforesaid, and upon receipt by the Trustee of the documents described in Section 8.06 and Section 11.02, the Trustee shall join with the Company in the execution of such amended or supplemental indenture unless such amended or supplemental indenture directly affects the Trustee’s own rights, duties or immunities under this Supplemental Indenture or otherwise, in which case the Trustee may in its discretion, but shall not be obligated to, enter into such amended or supplemental indenture.

(c) It shall not be necessary for the consent of the Holders of Notes under this Section 8.02 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 8.02 becomes effective, the Company shall mail to the Holders a notice briefly describing the amendment, supplement or waiver. However, the failure to give such notice, or any defect in the notice, will not impair or affect the validity of the amendment, supplement or waiver.

(e) For purposes of Article IX of the Base Indenture, a supplemental indenture which changes or eliminates any covenant or other provision of the Indenture which has been expressly included solely for the benefit of one or more particular series of Securities other than the Notes or which modifies the rights of the Holders of Securities of such series with respect to such covenant or other provision shall be deemed not to affect the rights under the Indenture of the Holders of Notes.

Section 8.03 Compliance with Trust Indenture Act.

Every amendment or supplement to this Supplemental Indenture or the Notes shall be set forth in an amended or supplemental indenture that complies with the TIA as then in effect.

Section 8.04 Revocation and Effect of Consents.

Until an amendment, supplement or waiver becomes effective, a consent to it by a Holder of a Note is a continuing consent by such Holder of a Note and every subsequent Holder of a Note or portion of a Note that evidences the same debt as the consenting Holder’s Note, even if notation of the consent is not made on any Note. However, any such Holder of a Note or subsequent Holder of a Note may revoke the consent as to its Note if the Trustee receives written notice of revocation before the date the amendment, supplement or waiver becomes effective. An amendment, supplement or waiver becomes effective in accordance with its terms and thereafter binds every Holder unless it makes a change described in any of clauses (1) through (6) of Section 8.02(a), in which case, the amendment, supplement or waiver shall bind only each Holder of a Note who has consented to such amendment, supplement or waiver and every subsequent Holder of a Note or portion of a Note that evidences the same indebtedness as the consenting Holder’s Note.

Section 8.05 Notation on or Exchange of Notes.

- 120 -

(a) The Trustee may place an appropriate notation about an amendment, supplement or waiver on any Note thereafter authenticated. The Company in exchange for all Notes may issue and the Trustee shall, upon receipt of a Company Order, authenticate new Notes that reflect the amendment, supplement or waiver.

(b) 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 8.06 Trustee to Sign Amendments, Etc.

The Trustee shall sign any amended or supplemental indenture authorized pursuant to this Article Eight if the amendment or supplement does not adversely affect the rights, duties, liabilities or immunities of the Trustee. Neither the Company nor any Guarantor may sign an amended or supplemental indenture until its Board of Directors approves it. In executing any amended or supplemental indenture, the Trustee shall be entitled to receive and (subject to the provisions of Section 601 of the Base Indenture) shall be fully protected in relying in good faith upon an Officers’ Certificate and an Opinion of Counsel stating that the execution of such amended or supplemental indenture is authorized or permitted by this Supplemental Indenture.

Section 8.07 Effect of Supplemental Indentures.

Upon the execution of any amended or supplemental indenture under this Article Eight, the Indenture (including this Supplemental Indenture) shall be modified in accordance therewith, and such amended or supplemental indenture shall form a part of the Indenture for all purposes; and every Holder of Notes theretofore or thereafter authenticated and delivered hereunder shall be bound thereby.

Nothing in this Supplemental Indenture shall limit or affect the provisions of Article IX or Section 513 of the Base Indenture insofar as relating to any amendment or waiver in respect of any series of Securities other than the Notes.

Article Nine

Guarantees

Article XIV of the Base Indenture shall not apply to the Notes, except as, and to the extent, described in this Article Nine.

Section 9.01 Guarantee.

(a) Subject to this Article Nine, each of the Guarantors hereby, jointly and severally, fully and unconditionally, guarantees, on a senior unsecured basis, to each Holder of a Note authenticated and delivered by the Trustee and to the Trustee and its successors and assigns, irrespective of the validity and enforceability of the Indenture, the Notes or the obligations of the Company hereunder or thereunder, that: (i) the principal of, premium, if any, and interest on the Notes will be promptly paid in full when due, whether at maturity, by acceleration, redemption or otherwise, and interest on the overdue principal of and interest on the Notes, if any, if lawful (subject in all cases to any applicable grace period provided herein), and all

- 121 -

other obligations of the Company to the Holders or the Trustee hereunder or thereunder will be promptly paid in full or performed, all in accordance with the terms hereof and thereof; and (ii) in case of any extension of time of payment or renewal of any Notes or any of such other obligations, that same will be promptly paid in full when due or performed in accordance with the terms of the extension or renewal, whether at stated maturity, by acceleration or otherwise. Failing payment when due of any amount so guaranteed or any performance so guaranteed for whatever reason, the Guarantors shall be jointly and severally obligated to pay the same immediately. Each Guarantor agrees that this is a guarantee of payment and not a guarantee of collection.

(b) The Guarantors hereby agree that, to the maximum extent permitted under applicable law, their obligations hereunder shall be unconditional, irrespective of the validity, regularity or enforceability of the Notes or the Indenture, the absence of any action to enforce the same, any waiver or consent by any Holder of the Notes with respect to any provisions hereof or thereof, the recovery of any judgment against the Company, any action to enforce the same or any other circumstance which might otherwise constitute a legal or equitable discharge or defense of a Guarantor. Subject to Section 6.06, each Guarantor hereby waives diligence, presentment, demand of payment, filing of claims with a court in the event of insolvency or bankruptcy of the Company, any right to require a proceeding first against the Company, protest, notice and all demands whatsoever and covenant that this Guarantee shall not be discharged except by complete performance of the obligations contained in the Notes and this Supplemental Indenture.

(c) If any Holder or the Trustee is required by any court or otherwise to return to the Company, any Guarantor or any custodian, trustee, liquidator or other similar official acting in relation to the Company or any Guarantor, any amount paid by the Company or any Guarantor to the Trustee or such Holder, the Guarantee hereunder of any Guarantor, to the extent theretofore discharged, shall be reinstated in full force and effect.

(d) Each Guarantor agrees that it shall not be entitled to any right of subrogation in relation to the Holders or the Trustee in respect of any obligations guaranteed hereby until payment in full of all obligations guaranteed hereby. Each Guarantor further agrees that, as between the Guarantors, on the one hand, and the Holders and the Trustee, on the other hand, (x) the maturity of the obligations guaranteed hereby may be accelerated as provided in Article Six for the purposes of this Guarantee, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the obligations guaranteed hereby, and (y) in the event of any declaration of acceleration of such obligations as provided in Article Six, such obligations (whether or not due and payable) shall forthwith become due and payable by the Guarantors for the purpose of this Guarantee. Each Guarantor that makes a payment or distribution under its Guarantee shall have the right to seek contribution from any non-paying Guarantor, in a pro rata amount based on the adjusted net assets of each Guarantor determined at the time of payment in accordance with GAAP, so long as the exercise of such right does not impair the rights of the Holders under the Guarantee.

(e) The obligations of each Guarantor under its Guarantee pursuant to this Article Nine shall rank equally in right of payment with other existing and future senior Indebtedness

- 122 -

of such Guarantor, and senior in right of payment to all existing and future Subordinated Indebtedness of such Guarantor.

Section 9.02 Limitation on Guarantor Liability.

Each Guarantor, and by its acceptance of Notes, each Holder, and the Trustee each hereby confirms that it is the intention of all such parties that the Guarantee of such Guarantor not constitute a fraudulent transfer or conveyance for purposes of Bankruptcy Law, the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act or any similar federal or state law to the extent applicable to any Guarantee. To effectuate the foregoing intention, the Trustee, the Holders and the Guarantors hereby irrevocably agree that the obligations of such Guarantor will be limited to the maximum amount which, after giving effect to all other contingent and fixed liabilities of such Guarantor, and after giving effect to any collections from or payments made by or on behalf of any other Guarantor in respect of the obligations of such other Guarantor under its Guarantee or pursuant to its contribution obligations under this Article Nine, will result in the obligations of such Guarantor under its Guarantee not constituting a fraudulent conveyance or fraudulent transfer under federal or state law. Until such time as the Notes are paid in full, each Guarantor hereby waives all rights of subrogation or contribution, whether arising by contract or operation of law (including any such right arising under federal Bankruptcy Law) or otherwise by reason of any payment by it pursuant to the provisions of this Article Nine.

Section 9.03 Guarantee Evidenced by Indenture; No Notation of Guarantee.

(a) The Guarantee of any Guarantor shall be evidenced solely by its execution and delivery of this Supplemental Indenture (or, in the case of any Guarantor that is not party to this Supplemental Indenture on the Issue Date, a supplemental indenture hereto) and not by an endorsement on, or attachment to, any Note or any Guarantee or notation thereof.

(b) Each Guarantor hereby agrees that its Guarantee set forth in Section 9.01 shall be and remain in full force and effect, subject to Section 9.04, notwithstanding any failure to endorse on any Note a notation of such Guarantee.

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

(d) Subsequent to the Issue Date, in the event a Restricted Subsidiary is required by Section 4.12 to guarantee the Company’s obligations under the Notes and this Supplemental Indenture, the Company shall cause such Restricted Subsidiary to execute a supplemental indenture to this Supplemental Indenture substantially in the form included in Exhibit D hereto in accordance with Section 4.12 and this Article Nine, to the extent applicable, which supplemental indenture shall be executed and delivered on behalf of such Guarantor by an Officer of such Guarantor.

Section 9.04 Releases of Guarantors.

- 123 -

(a) The Guarantee of a Guarantor will be deemed automatically and unconditionally released and discharged from all of its obligations under its Guarantee without any further action on the part of the Trustee or any Holder of the Notes:

(1) in connection with any sale or other disposition of all or substantially all of the assets of such Guarantor (including by way of merger or consolidation) to one or more Persons that are not (either before or after giving effect to such transaction) the Company or a Restricted Subsidiary, if the sale or other disposition of all or substantially all of the assets of such Guarantor complies with Section 4.11;

(2) in connection with any sale of all of the Capital Stock of a Guarantor to one or more Persons that are not (either before or after giving effect to such transaction) the Company or a Restricted Subsidiary, if the sale of all such Capital Stock of such Guarantor complies with Section 4.11;

(3) if the Company properly designates such Guarantor as a Non-Guarantor Restricted Subsidiary and such Restricted Subsidiary is not required at such time to issue a Guarantee of the Notes pursuant to Section 4.12;

(4) if the Company properly designates a Guarantor as an Unrestricted Subsidiary;

(5) if a Guarantor under any Credit Facility is released from its guarantee issued pursuant to the terms of any Credit Facility of the Company or any direct or indirect Restricted Subsidiary, and such Guarantor is not an obligor under any Indebtedness of the Company or any domestic Restricted Subsidiary other than the Notes in excess of $5.0 million in aggregate principal amount;

(6) upon the liquidation or dissolution of such Guarantor; provided that no Default or Event of Default has occurred and is continuing; or

(7) if Legal Defeasance or Covenant Defeasance of the Notes has been effected or Satisfaction and Discharge has been effected in accordance with the procedures set forth in Article Seven or Article Ten, as applicable;

provided that any such release and discharge pursuant to clauses (1), (2), (3), (4), (5), (6) and (7) above shall occur only to the extent that all obligations of such Guarantor under all of its guarantees of, and under all of its pledges of assets or other security interests which secure any, Indebtedness of the Company and the domestic Restricted Subsidiaries (other than the Notes) having an aggregate principal amount in excess of $5.0 million shall also terminate at such time.

(b) Any Guarantor not released from its obligations under its Guarantee shall remain liable for the full amount of principal of and interest on the Notes and for the other obligations of any Guarantor under this Supplemental Indenture as provided in this Article Nine.

- 124 -

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 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 to the Company on its request or (if then held by the Company) shall be discharged from such trust; and the Holder of such Note shall thereafter look only to the Company for payment thereof, and all liability of the Trustee or such Paying Agent with respect to such trust money, and all liability of the Company as trustee thereof, shall thereupon cease; provided, however, that the Trustee or such Paying Agent, before being required to make any such repayment, may, at the expense of the Company, cause to be

The waiver may not be effective to waive liabilities under the federal securities laws.
