ARTICLE ONE

Section 1.01                             Designation and Amount; Ranking Payments; Denomination.

The Notes shall be designated as the “6¼% Senior Notes due 2023.” 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 $350,000,000 (except for Notes authenticated and delivered upon registration or transfer of, or in exchange for, or in lieu of other Notes pursuant to Section 3.06, Section 4.11(h), Section 4.17(c) 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 4.02 of this Supplemental Indenture.

Initially, ▇▇▇▇▇ 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

2

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 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 form set forth in Exhibit A hereto, 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 form of Note attached as Exhibit A hereto shall constitute, and are hereby expressly made, a part of this Supplemental Indenture and the Company, any Guarantors 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 A 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 reduced or increased, as appropriate, to reflect exchanges and redemptions on the records of the Trustee and the Depositary or its nominee.

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

The registration, registration of transfers and exchanges of Notes shall be effected in accordance with Section 305 of the Base Indenture.

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, and (c) 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:

(i)             the aggregate principal amount of such Additional Notes to be authenticated and delivered pursuant to the Indenture;

(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)       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 Exhibit A hereto and any circumstances in addition to or in lieu of those set forth in Exhibit A 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.

(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 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 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 shall have the

4

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, 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.  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 shall be issued upon original issue as Global Notes. 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 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)                                 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.

(e)                                  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.

(f)                                   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.

(g)                                  The Trustee shall also authenticate and deliver Notes at the times and in the manner specified in Section 3.06, Section 4.11(h), Section 4.17(c) and Section 8.05 hereof and Section 305 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                             Methods of Receiving Payments on the Notes.

The principal of (and premium, if any) and interest on the Notes shall be payable at the office or agency of the Company maintained for such purpose pursuant to Section 4.02; 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 1.07                             Registrar and Paying Agent.

(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.  The Company shall notify the Trustee in writing of the name and address of any Agent not a party to this Supplemental Indenture.  If the Company fails to appoint or maintain another entity as Registrar or Paying Agent, the Trustee shall act as such.  The Company or any of its Restricted Subsidiaries may act as Paying Agent or Registrar.

(b)                                 The Company initially appoints The Depository Trust Company (“DTC”) to act as Depositary with respect to the Global Notes.

(c)                                  The Company initially appoints the Trustee to act as the Registrar and Paying Agent and to act as Custodian with respect to the Global Notes.

Section 1.08                             Paying Agent to Hold Money in Trust.

By no later than 12:30 p.m. (New York City time) on the date on which any principal of, premium, if any, or interest on any Note is due and payable, the Company shall deposit with the Paying Agent a sum sufficient in immediately available funds to pay such principal, premium or interest when due.  The Company shall require each Paying Agent other than the Trustee to agree in writing that the Paying Agent shall hold in trust for the benefit of the Holders or the Trustee all money held by the Paying Agent for the payment of principal or premium, if any, or interest on the Notes, and shall notify the Trustee of any default by the Company in making any such payment.  While any such default continues, the Trustee may require a Paying Agent to pay all money held by it to the Trustee.  The Company at any time may require a Paying Agent to pay all money held by it to the Trustee.  Upon payment over to the Trustee, the Paying Agent (if other than the Company or one of its Subsidiaries) shall have no further liability for the money.  If the Company or any of its Subsidiaries acts as Paying Agent, it shall segregate and hold in a separate trust fund for the benefit of the Holders all money held by it as Paying Agent.  Upon any bankruptcy or reorganization proceedings relating to the Company, the Trustee shall serve as Paying Agent for the Notes.

Section 1.09                             Holder Lists.

The Trustee shall preserve in as current a form as is reasonably practicable the most recent list available to it of the names and addresses of all Holders and shall otherwise comply with TIA Section 312(a).  If the Trustee is not the Registrar, the Company shall furnish to the Trustee at least five Business Days before each interest payment date and at such other times as the Trustee may request in writing, a list in such form and as of such date as the Trustee may reasonably require of the names and addresses of the Holders and the Company shall otherwise comply with TIA Section 312(a).

Section 1.10                             Outstanding Notes.

(a)                                 The Notes outstanding at any time are all the Notes authenticated by the Trustee except for those canceled by it, those delivered to it for cancellation and those described in this Section 1.10 as not outstanding.  The aggregate principal amount of any outstanding Global Note that is outstanding at any time shall be such aggregate principal amount of Notes that is endorsed thereon as being represented thereby at such time.  Except as set forth in Section 1.11, a Note does not cease to be outstanding because the Company or an Affiliate of the Company holds the Note.

(b)                                 If a Note is replaced pursuant to Section 306 of the Base Indenture, it ceases to be outstanding unless the Trustee receives proof satisfactory to it that the replaced Note is held by a “protected purchaser” within the meaning of Section 8-405 of the Uniform Commercial Code.

(c)                                  If the principal amount of any Note is considered paid under Section 4.01, it ceases to be outstanding and interest on it ceases to accrue.

(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,

7

money 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 1.11                             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.

(iii)                               if any Note is being redeemed in part, the portion of the principal amount of such Note to be redeemed and that, after the redemption date upon surrender of such Note, a new Note or Notes in principal amount equal to the

49

unredeemed portion of the original Note shall be issued in the name of the Holder thereof upon cancellation of the original Note;

(iv)                              the name and address of the Paying Agent;

(v)                                 that Notes called for redemption shall be surrendered to the Paying Agent to collect the redemption price and become due on the date fixed for redemption;

(vi)                              that, unless the Company defaults in making such redemption payment, interest, if any, on Notes called for redemption ceases to accrue on and after the redemption date and the only remaining right of Holders of such Notes is to receive payment of the redemption price upon surrender to the Paying Agent of the Notes redeemed;

(vii)                           the paragraph of the Notes and/or section of this Supplemental Indenture pursuant to which the Notes called for redemption are being redeemed;

(ix)                              any conditions precedent to the redemption.

(b)                                 At the Company’s request, the Trustee shall give the notice of redemption in the Company’s name and at its expense; provided, however, that the Company shall have delivered to the Trustee, as provided in Section 3.01, an Officers’ Certificate requesting that the Trustee give such notice and setting forth the information to be stated in such notice as provided in Section 3.03(a).  The notice, if mailed (or, in the case of Global Notes, with respect to notices given by the Trustee on behalf of the Company, sent) in the manner provided herein, shall be presumed to have been given, whether or not the Holder receives such notice.  Failure to give timely notice or any defect in the notice shall not affect the validity of the redemption.

Section 3.04                             Effect of Notice of Redemption.

Once notice of redemption is mailed (or, in the case of Global Notes, with respect to notices given by the Trustee on behalf of the Company, sent in accordance with the applicable procedures of the Depositary) in accordance with Section 3.03, Notes called for redemption become irrevocably due and payable on the redemption date at the redemption price, subject only to any conditions precedent set forth therein.

Section 3.05                             Deposit of Redemption Price.

(a)                                 Not later than 12:30 p.m. (New York City time) on the redemption date, the Company shall deposit with the Trustee or with the Paying Agent (or, if the Company or a Subsidiary thereof is acting as its own Paying Agent, segregate and hold in trust as provided in Section 1.08) money sufficient to pay the redemption price of and accrued interest on all Notes to be redeemed on that date.  The Trustee or the Paying Agent shall promptly return to the Company any money deposited with the Trustee or the Paying Agent by the Company in excess

50

of the amounts necessary to pay the redemption price of, and accrued interest on, all Notes to be redeemed.

(b)                                 If the Company complies with the provisions of Section 3.05(a), on and after the redemption date, interest shall cease to accrue on the Notes or the portions of Notes called for redemption, unless the redemption is not effective due to the failure of conditions precedent described in the notice of redemption to be fulfilled.  If a Note is redeemed on or after an interest record date but on or prior to the related interest payment date, then any accrued and unpaid interest shall be paid to the Holder in whose name such Note was registered at the close of business on such record date.  If any Note called for redemption shall not be so paid upon surrender for redemption because of the failure of the Company to comply with Section 3.05(a), interest shall be paid on the unpaid principal, from the redemption date until such principal is paid, and to the extent lawful on any interest not paid on such unpaid principal, in each case at the rate provided in the Notes and in Section 4.01.

Section 3.06                             Notes Redeemed in Part.

Upon surrender of a Note that is redeemed in part, the Company shall issue and the Trustee shall authenticate for the Holder at the expense of the Company a new Note equal in principal amount to the unredeemed portion of the Note surrendered.  No Notes in denominations of $2,000 or less shall be redeemed in part.  For all purposes of this Article Three, unless the context otherwise requires, all provisions relating to the redemption of Notes shall relate, in the case of any Notes redeemed or to be redeemed only in part, to the portion of the principal amount of such Notes which has been or is to be redeemed.

Section 3.07                             Optional Redemption.

(a)                                 On or after March 15, 2018, the Company may redeem all or a portion of the Notes, on not less than 30 nor more than 60 days’ prior notice, in amounts of $2,000 or whole multiples of $1,000 in excess thereof, at the following redemption prices (expressed as percentages of the principal amount), plus accrued and unpaid interest, if any, thereon, to the applicable redemption date (subject to the rights of Holders of record on relevant record dates to receive interest due on the relevant interest payment date), if redeemed during the twelve-month period beginning on March 15 of the years indicated below:

(b)                                 In addition, at any time and from time to time prior to March 15, 2018, the Company may use funds in an amount not exceeding the amount of the net cash proceeds of one or more Equity Offerings to redeem up to an aggregate of 35% of the aggregate principal amount of Notes issued under this Supplemental Indenture (including the principal amount of any Additional Notes issued under this Supplemental Indenture) at a redemption price equal to

51

106.25% of the aggregate principal amount of the Notes redeemed, plus accrued and unpaid interest, if any, to the redemption date (subject to the rights of Holders of record on relevant record dates to receive interest due on the relevant interest payment date).  At least 65% of the aggregate principal amount of Notes (including the principal amount of any Additional Notes issued under this Supplemental Indenture) shall remain outstanding immediately after the occurrence of such redemption.  In order to effect this redemption, the Company shall complete such redemption no later than 180 days after the closing of the related Equity Offering.  Notice of any redemption pursuant to this clause (b) may be given prior to the completion of the applicable Equity Offering, and any such redemption or notice may, at the Company’s discretion, be subject to one or more conditions precedent, including completion of such Equity Offering.  If any such conditions do not occur, the Company will provide prompt written notice to the Trustee rescinding such redemption, and such redemption and notice of redemption shall be rescinded and of no force or effect.  Upon receipt of such notice, the Trustee will promptly send a copy of such notice to the Holders of the Notes to be redeemed in the same manner in which the notice of redemption was given.

(c)                                  The Notes may also be redeemed, in whole or in part, at any time or from time to time prior to March 15, 2018 at the option of the Company at a redemption price equal to 100% of the principal amount of the Notes redeemed plus the Applicable Premium as of, and accrued and unpaid interest, if any, to, the applicable redemption date (subject to the right of Holders of record on the relevant record date to receive interest due on the relevant interest payment date).

(d)                                 If a Change of Control occurs at any time prior to March 15, 2016, the Company may, at its option, redeem all, but not less than all, of the Notes upon not less than 30 nor more than 60 days’ prior notice, at a redemption price equal to 110.0% of the principal amount of the Notes redeemed, plus accrued and unpaid interest, if any, to the redemption date (subject to the rights of Holders of record on the relevant record date to receive interest due on the relevant interest payment date).  If the Company elects to exercise this redemption right, the Company must do so by mailing a redemption notice to each Holder at its registered address (or, in the case of Global Notes, with respect to notices given by the Trustee on behalf of the Company, sending in accordance with the applicable procedures of the Depositary)  with a copy to the Trustee within 60 days following the Change of Control (or, at the Company’s option, prior to such Change of Control but after the transaction giving rise to such Change of Control is publicly announced).  Any such redemption may be conditioned upon the Change of Control occurring if the notice is mailed (or, in the case of Global Notes, with respect to notices given by the trustee on behalf of the Company, sent) prior to the Change of Control.  If the Change of Control does not occur, the Company will provide prompt written notice to the Trustee rescinding such redemption, and such redemption and notice of redemption shall be rescinded and of no force or effect.  Upon receipt of such notice, the Trustee will promptly send a copy of such notice to the Holders in the same manner in which the notice of redemption was given.  If the Company exercises the Change of Control redemption right set forth in this Section 3.07(d), the Company will not be required to make the Change of Control Offer described under Section 4.17 unless or until there is a default in payment of the redemption price.

52

(e)                                  Pursuant to Section 4.17(h), the Company may also redeem all, but not less than all, of the outstanding Notes, at the redemption price and subject to the conditions set forth in Section 4.17(h).

(f)                                   Any redemption pursuant to this Section 3.07 (other than as expressly provided otherwise in this Section 3.07) shall be made pursuant to the provisions of Sections 3.01 through 3.06.

Section 3.08                             Mandatory Redemption.

The Company is not required to make mandatory redemption or sinking fund payments with respect to the Notes.

Section 3.09                             Application of Trust Money.

All money deposited with the Trustee pursuant to Section 3.05 shall be held in trust and applied by it, in accordance with the provisions of the Notes and this Supplemental Indenture, to the payment, either directly or through any Paying Agent (including the Company acting as its own Paying Agent) as the Trustee may determine, to the Persons entitled thereto, of the principal (and premium, if any) and interest for whose payment such money has been deposited with the Trustee; but such money need not be segregated from other funds except to the extent required by law.

Section 3.10                             No Limit on Other Purchases.

Nothing in this Supplemental Indenture or the Notes shall prohibit or limit the right of the Company or any Affiliate of the Company from time to time to repurchase the Notes at any price in open market purchases or negotiated transactions or by tender offer or otherwise without any notice to or consent by Holders.  Any Notes purchased by the Company may, to the extent permitted by law, be held or resold or may, at the Company’s option, be delivered to the Trustee for cancellation.  Any Notes delivered to the Trustee for cancellation may not be reissued or resold and will be promptly cancelled.

(e)                                  Delivery of such reports, information and documents to the Trustee is for informational purposes only, and the Trustee’s receipt of such shall not constitute constructive notice of any information contained therein or determinable from information contained therein, including the Company’s compliance with any of its covenants hereunder (as to which the Trustee is entitled to rely exclusively on Officers’ Certificates).

Section 4.04                             Compliance Certificate.

(a)                                 The Company shall deliver to the Trustee, within 120 days after the end of each fiscal year ending after the Issue Date, an Officers’ Certificate stating that a review of the activities of the Company and its Restricted Subsidiaries during the preceding fiscal year has been made under the supervision of the signing Officers with a view to determining whether the Company has kept, observed, performed and fulfilled their respective obligations under the Supplemental Indenture and the Base Indenture (as it relates to the Notes) and further stating, as to each such Officer signing such certificate, that to the best of his or her actual knowledge, the Company has kept, observed, performed and fulfilled its obligations under the Supplemental Indenture and the Base Indenture (as it relates to the Notes) and is not in default in the performance or observance of any of the material terms, provisions and conditions of the Indenture with respect to the Notes, in each case, so as not to result in any Default or Event of Default (or, if a Default or Event of Default shall have occurred and be continuing, describing all such Defaults or Events of Default of which he or she may have knowledge and what action the Company is taking or propose to take with respect thereto).

(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 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)                                 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;

58

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) or clause (2), (3), (11) or this clause (9) of this paragraph (b) of this Section 4.07;

(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.

(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.

59

(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 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.

(C)                               the aggregate Net Cash Proceeds, or the Fair Market Value of property other than cash, received after the Measurement Date by the Company (other than from any Restricted Subsidiary) upon the exercise of any options, warrants or rights to purchase Qualified Capital Stock of the Company (and excluding the Net Cash Proceeds from the exercise of any options, warrants or rights to purchase Qualified Capital Stock financed, directly or indirectly, using funds borrowed from the Company or any Restricted Subsidiary until and to the extent such borrowing is repaid);

(E)                                (a)                                 in the case of a net reduction in any Investment constituting a Restricted Payment (including any Investment in an Unrestricted Subsidiary) made after the Measurement Date resulting from dividends, distributions, redemptions or repurchases, proceeds of sales or other dispositions thereof, interest payments, repayments of loans or advances, or other transfers of cash or properties (including transfers as a result of merger or liquidation), in each case to the Company or to any Restricted Subsidiary from any Person (other than the Company or a Restricted Subsidiary), an amount (in each such case to the extent not included in Consolidated Net Income) equal to the amount received with respect to such Investment, less the cost of the disposition of such Investment and net of taxes, 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”):

(1)                                 the payment of any dividend within 60 days after the date of declaration thereof, if at such date of declaration such payment was permitted by the provisions of paragraph (a) of this Section 4.08, in which event such payment shall have been deemed to have been paid on such date of declaration and shall not have been deemed a “Permitted Payment” for purposes of the calculation required by paragraph (a) of this Section 4.08;

(2)                                 the purchase, repurchase, redemption, or other acquisition or retirement for value of any shares of any class of Capital Stock of the Company in

(1)                                 such Transaction is on terms that are not materially less favorable to the Company or such Restricted Subsidiary, as the case may be, than those that would be available in a comparable Transaction in arm’s-length dealings with a party that is not an Affiliate of the Company,

(3)                                 the payment of reasonable and customary compensation and fees to officers or directors of the Company or any Restricted Subsidiary who are not employees of the Company or any Affiliate of the Company,

67

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,

from a financial point of view or that such transaction meets the requirements of clause (1) of Section 4.09(a).

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.

(a)                                 The Company will not, and will not cause or 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 the 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

69

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 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:

(1)                                 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);

(2)                                 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;

(3)                                 purchase Notes;

(4)                                 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

(5)                                 make any combination of payment, repayment, investment or reinvestment permitted by the foregoing clauses (1) through (4).

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.

70

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 “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(d)) (subject to the rights of Holders of record on relevant record dates to receive interest due on the relevant 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 pro rata according to the principal amount of 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 the second sentence of this Section 4.11(c) and provided that all Holders 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, in the case of Global Notes, if such notice is given by the Trustee on behalf of the Company, sent in accordance with the applicable procedures of the Depositary), to the Holders (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 to make an informed decision with respect to the Prepayment Offer.  The Prepayment Offer Notice will state, among other things:

71

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

(2)                                 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;

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

(4)                                 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 (or, in the case of Global Notes, sent) (the “Asset Sale Purchase Date”);

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

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

(7)                                 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:

(1)                                 the name of the Holder,

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

72

(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 his election is to be withdrawn,

(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 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

73

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 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 B attached hereto, executed by such Restricted Subsidiary, providing for a full and unconditional guarantee on a senior unsecured basis by such Restricted Subsidiary of the Company’s obligations under the Notes, this Supplemental Indenture and the Base Indenture (as it relates to the Notes) to the same extent as that set forth as to the Guarantors in Article Nine, subject to such Restricted Subsidiary ceasing to be a Guarantor when its Guarantee is released in accordance with the terms of this Supplemental 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 B attached hereto providing for a full and unconditional guarantee on a senior unsecured basis by such Restricted Subsidiary or Restricted Subsidiaries of the Company’s obligations under the Notes, this Supplemental Indenture and the Base Indenture (as it relates to the Notes) to the same extent as that set forth as to the Guarantors in Article Nine, such that the collective Consolidated Net Worth of all remaining Non-Guarantor Restricted Subsidiaries does not exceed $5.0 million.

74

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:

(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 indentures 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

75

Person, so acquired, so long as the agreement containing such restriction does not violate any other provision of this Supplemental 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 avoiding the restrictions imposed by this Section 4.13) that limit the right of the debtor or lessee to dispose of the assets subject to such Liens;

(6)                                 provisions restricting subletting or assignment of any lease governing a leasehold interest (including leases governing leasehold interests or farm-in agreements or farm-out agreements relating to leasehold interests in Oil and Gas Properties) of the Company or any Restricted Subsidiary, or restrictions in licenses (including licenses of intellectual property) relating to the property covered thereby, or other encumbrances or restrictions in agreements or instruments relating to specific assets or property that restrict generally the transfers of such assets or property; provided that such encumbrances or restrictions do not materially impact the ability of the Company to permit payments on the Notes when due as required by the terms of this Supplemental Indenture;

(7)                                 agreements with respect to asset sales, including the sale or other disposition of all or substantially all the Capital Stock of a Restricted Subsidiary, permitted to be made under the provisions of Section 4.11 that limit the transfer of such assets or assets of such Restricted Subsidiary (or distribution on such Capital Stock) pending the closing of such sale;

(8)                                 shareholders’, partnership, joint venture and similar agreements entered into in the ordinary course of business; provided that such encumbrances or restrictions do not apply to any Restricted Subsidiaries other than the applicable company, partnership, joint venture or other entity;

(9)                                 cash, Cash Equivalents or other deposits, or net worth requirements or similar requirements, imposed by suppliers, landlords or customers under contracts entered into in the ordinary course of business;

(10)                          any Credit Facility or agreement governing Indebtedness of the Company or any Restricted Subsidiary permitted to be incurred under the provisions of Section 4.07; provided that such encumbrances or restrictions are not materially more restrictive, taken as a whole, as determined by the Company in good faith, than those contained in the Senior Credit Agreement, in the indentures governing the Existing Senior Notes or in this Supplemental Indenture as in effect on the Issue Date;

(11)                          restrictions of the nature described in clause (4) of Section 4.13(a) by reason of customary non-assignment provisions in Hydrocarbon purchase or sale or

(12)                          Commodity Agreements, Currency Agreements or Interest Rate Agreements permitted from time to time under this Supplemental Indenture;

(13)                          any Preferred Stock issued by a Restricted Subsidiary; provided that the issuance of such Preferred Stock is permitted pursuant to Section 4.07 and the terms of such Preferred Stock do not expressly restrict the ability of such Restricted Subsidiary to pay dividends or make any other distributions on its Capital Stock (other than requirements to pay dividends or liquidation preferences on such Preferred Stock prior to paying any dividends or making any other distributions on such other Capital Stock);

(14)                          Permitted Refinancing Indebtedness; provided that the restrictions contained in the agreements governing such Permitted Refinancing Indebtedness are no more restrictive, taken as a whole, than those contained in the agreements governing the Indebtedness being Refinanced;

(15)                          encumbrances and restrictions contained in contracts entered into in the ordinary course of business, not relating to any Indebtedness, and that do not, individually or in the aggregate, detract from the value of, or from the ability of the Company and the Restricted Subsidiaries to realize the value of, property or assets of the Company or any Restricted Subsidiary in any manner material to the Company or any Restricted Subsidiary; and

(16)                          any agreement, amendment, modification, restatement, extension, renewal, supplement, refunding, replacement or Refinancing that amends, modifies, restates, extends, renews, refunds, replaces or Refinances the agreements containing the encumbrances or restrictions in the foregoing clauses (1) through (15), or in this clause (16); provided that the terms and conditions of any such encumbrances or restrictions are no more restrictive in any material respect taken as a whole, as determined by the Company in good faith, than those under or pursuant to the agreement so amended, modified, restated, extended, renewed, refunded, replaced or Refinanced.

Section 4.14                             Sale and Leaseback Transactions.

The Company will not, and will not cause or permit any Restricted Subsidiary to, enter into any Sale and Leaseback Transaction; provided that the Company or any Restricted Subsidiary may enter into a Sale and Leaseback Transaction if:

(1)                                 the Company or such Subsidiary could have incurred Indebtedness at the time of such Sale and Leaseback Transaction on a pro forma basis (on the assumption such transaction occurred on the first day of the four-quarter period for which financial statements are available ending immediately prior to such transaction with the appropriate adjustments with respect to such transaction being included in such pro forma calculation) in an amount equal to the Attributable Indebtedness relating to such Sale and

77

Leaseback Transaction pursuant to the Consolidated Fixed Charge Coverage Ratio test set forth in paragraph (a) of Section 4.07;

(2)                                 the gross cash proceeds of such Sale and Leaseback Transaction are at least equal to the Fair Market Value of the property that is the subject of such Sale and Leaseback Transaction; and

(3)                                 the transfer of assets in such Sale and Leaseback Transaction is permitted by, and the Company applies the proceeds of such transaction in the same manner and to the same extent as Net Available Cash and Excess Proceeds from an Asset Sale in compliance with, Section 4.11.

Section 4.15                             Unrestricted Subsidiaries.

(a)                                 The Board of Directors of the Company may designate after the Issue Date any of the Company’s Subsidiaries as an Unrestricted Subsidiary under this Supplemental Indenture (a “Designation”) only if:

(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;

(3)                                 such Unrestricted Subsidiary does not own any Capital Stock in any Restricted Subsidiary which is not simultaneously being designated an Unrestricted Subsidiary;

(4)                                 such Unrestricted Subsidiary is not liable, directly or indirectly, with respect to any Indebtedness other than Unrestricted Subsidiary Indebtedness; provided that an Unrestricted Subsidiary may provide a Guarantee for the Notes; and

(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.

78

(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.

(c)                                  The Company shall not and shall not cause or permit any Restricted Subsidiary to at any time:

(1)                                 provide credit support for, guarantee or subject any of its property or assets (other than the Capital Stock of any Unrestricted Subsidiary) to the satisfaction of, any Indebtedness of any Unrestricted Subsidiary (including any undertaking, agreement or instrument evidencing such Indebtedness) or enter into or become a party to any agreement, contract, arrangement or understanding with any Unrestricted Subsidiary, the terms of which, together with the terms of all other agreements, contracts, arrangements and understandings with such Unrestricted Subsidiary, taken as a whole, in the good-faith judgment of the Board of Directors of the Company, are less favorable to the Company and the Restricted Subsidiaries than those that would be available in a comparable transaction in arm’s-length dealings with a party that is not an Affiliate of the Company; provided that this Section 4.15 shall not be deemed to prevent Permitted Investments, Restricted Payments or Permitted Payments in Unrestricted Subsidiaries that are otherwise allowed under this Supplemental Indenture, or

(2)                                 be directly or indirectly liable for any Indebtedness of any Unrestricted Subsidiary (other than by pledge of the Capital Stock thereof).

(d)                                 For purposes of this Section 4.15, the Designation of a Subsidiary of the Company as an Unrestricted Subsidiary shall be deemed to be the Designation of all of the Subsidiaries of such Subsidiary as Unrestricted Subsidiaries.  Unless so designated as an Unrestricted Subsidiary, any Person that becomes a Subsidiary of the Company will be classified as a Restricted Subsidiary.

(e)                                  The Company may revoke any Designation of a Subsidiary as an Unrestricted Subsidiary (a “Revocation”) if:

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

(2)                                 all Indebtedness of such Unrestricted Subsidiary outstanding immediately following such Revocation would, if incurred at such time, have been permitted to be incurred for all purposes of this Supplemental Indenture; and

(3)                                 unless such redesignated Subsidiary shall not have any Indebtedness outstanding (other than Indebtedness that would be Permitted Debt), immediately after giving effect to such proposed Revocation, and after giving pro forma effect to the incurrence of any such Indebtedness of such redesignated Subsidiary as if such Indebtedness was incurred on the date of the Revocation, the Company could incur $1.00 of additional Indebtedness (other than Permitted Debt) pursuant to Section 4.07.

79

(f)                                   All Designations and Revocations shall be evidenced by a Board Resolution of the Board of Directors of the Company delivered to the Trustee certifying compliance with the provisions of this Section 4.15.

Section 4.16                             Payments for Consent.

Neither the Company nor any Restricted Subsidiary shall, directly or indirectly, pay or cause to be paid any consideration, whether by way of interest, fee or otherwise, to any Holder for or as an inducement to any consent, waiver or amendment of any of the terms or provisions of this Supplemental Indenture or the Notes unless such consideration is offered to be paid or is paid to all Holders that consent, waive or agree to amend in the time frame set forth in the solicitation documents relating to such consent, waiver or agreement.

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 March 15, 2016, within 60 days thereafter will have given) notice of redemption of all the Notes pursuant to 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 in this Section 4.17 (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 the relevant 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 March 15, 2016, within 60 days thereafter will have given) notice of redemption of all the Notes pursuant to 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 the address appearing for such Holder in the Security Register (or, in the case of Global Notes, if such notice is given by the Trustee on behalf of the Company, sent in accordance with the applicable procedures of the Depositary).  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;

80

(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 fixed by the Company on a Business Day no earlier than 30 days nor later than 60 days from the date the Change of Control Purchase Notice is mailed (or, in the case of Global Notes, sent), or such later date as is necessary to comply with requirements under the Exchange Act; 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 are required to follow in order to tender their Notes and the procedures that Holders 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.

If any of the Notes subject to a Change of Control 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.

(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 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 307 of the Base Indenture.  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

81

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.

(e)                                  A tender made in response to a Change of Control Purchase Notice may be withdrawn if the Company receives, not later than one Business Day prior to the Change of Control Purchase Date, a telegram, telex, facsimile transmission or letter, specifying, as applicable:

(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 with the applicable tender offer rules, including the requirements of Rule 14e-1 under the Exchange Act, and any other applicable securities laws or regulations thereunder in connection with a Change of Control Offer.  To the extent that the provisions of any securities laws or regulations conflict with the provisions

82

relating to the Change of Control Offer in this Section 4.17, 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 provisions of this Section 4.17, the Company will not be required to make a Change of Control Offer under the following circumstances: (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 given (or, if a Change of Control occurs prior to March 15, 2016, 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, and 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 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 the relevant 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 ▇▇▇▇▇’▇ 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 has occurred and is continuing, then, beginning on that day and on each day thereafter until a Reversion Date, if any (as described in 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;

83

(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 to Section 4.15.

(c)                                  Notwithstanding Sections 4.19(a) and (b), if the rating assigned by either ▇▇▇▇▇’▇ or S&P should subsequently decline to below Baa3 or BBB-, respectively, the Suspended Covenants will be reinstituted as of and from the date of such rating decline (such date, a “Reversion Date”) and on the Reversion Date and on 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)(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)(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)(3)(A) and (y) the items specified in clauses (a)(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)(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 a Reversion Date (or thereafter) under any Suspended Covenant, solely as a result of, or as a result of the continued existence on or after a 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 a Reversion Date of any obligations arising from transactions which occurred, during a Suspension Period.

Successors

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

Section 5.01                             Consolidation, Merger and Sale of Assets.

(a)                                 The Company will not, in any Transaction, (x) consolidate with or merge with or into any other Person or (y) sell, assign, convey, transfer, lease or otherwise dispose of all or substantially all of its properties and assets to any Person, or (in the case of clause (y)) permit any of the Restricted Subsidiaries to enter into any Transaction, if such Transaction, in the aggregate, would result in a sale, assignment, conveyance, transfer, lease or disposition of all or substantially all of the properties and assets of the Company and the Restricted Subsidiaries on a Consolidated basis to any other Person (other than the Company or one or more Restricted Subsidiaries) unless at the time and after giving effect thereto:

(1)                                 either (a) the Person (if other than the Company) formed by such consolidation or into which the Company is merged or the Person which acquires by sale, assignment, conveyance, transfer, lease or disposition all or substantially all of such properties and assets (the “Surviving Entity”) will be a corporation, limited liability company or limited partnership duly organized and validly existing under the laws of the United States of America, any state thereof or the District of Columbia or (b) the Company will be the Surviving Entity;

(2)                                 if the Company is merging into, consolidating with or disposing of assets and is not the Surviving Entity, (a) the Surviving Entity shall expressly assume, by a supplemental indenture (or other agreement reasonably satisfactory to the Trustee), in a form reasonably satisfactory to the Trustee, all the obligations of the Company under the Notes, the Base Indenture (as it relates to the Notes) and this Supplemental Indenture and (b) if the Surviving Entity is not a corporation, then a Subsidiary of the Surviving Entity that is a corporation shall execute a supplemental indenture pursuant to which it shall become a co-obligor of the Surviving Entity’s obligations under the Notes, the Base Indenture (as it relates to the Notes) and this Supplemental Indenture;

(3)                                 except in the case (a) a Restricted Subsidiary merges into, consolidates with or disposes of assets to the Company or (b) the Company merges into, consolidates with or disposes of assets to a Guarantor, immediately after giving effect to such transaction on a pro forma basis (and treating any Indebtedness not previously an obligation of the Company or any Restricted Subsidiary which becomes the obligation of the Company or any Restricted Subsidiary as a result of such transaction as having been incurred at the time of such transaction), no Default or Event of Default will have occurred and be continuing;

(4)                                 except in the case (a) a Restricted Subsidiary merges into, consolidates with or disposes of assets to the Company or (b) the Company merges into, consolidates with or disposes of assets to a Guarantor, immediately after giving effect to

85

such transaction on a pro forma basis (on the assumption that the transaction occurred on the first day of the four-quarter period for which financial statements are available ending immediately prior to the consummation of such transaction with the appropriate adjustments with respect to the transaction being included in such pro forma calculation), either (i) the Company (or the Surviving Entity if the Company is merging into, consolidating with or disposing of assets and is not the Surviving Entity) could on the first day following such four-quarter period incur $1.00 of additional Indebtedness (other than Permitted Debt) under Section 4.07 or (ii) the Consolidated Fixed Charge Coverage Ratio for the Company (or the Surviving Entity if the Company is merging into, consolidating with or disposing of assets and is not the Surviving Entity) would be at least as great as the Consolidated Fixed Charge Coverage for the Company immediately prior to such transactions;

(5)                                 if the Company is merging into, consolidating with or disposing of assets and is not the Surviving Entity, at the time of the transaction, each Guarantor, if any, unless it is the other party to the transactions described above, will have by supplemental indenture confirmed that its Guarantee shall apply to the Surviving Entity’s obligations under this Supplemental Indenture, the Base Indenture (as it relates to the Notes) and the Notes;

(6)                                 at the time of the transaction, if any of the property or assets of the Company or any Restricted Subsidiary would thereupon become subject to any Lien, Section 4.10 is complied with; and

(7)                                 at the time of the transaction, the Company or (if the Company is merging into, consolidating with or disposing of assets and is not the Surviving Entity) the Surviving Entity will have delivered, or caused to be delivered, to the Trustee an Officers’ Certificate and an Opinion of Counsel, each to the effect that such consolidation, merger, transfer, sale, assignment, conveyance, transfer, lease or other transaction and the supplemental indenture in respect thereof comply with this Supplemental Indenture and the Base Indenture (as it relates to the Notes).

(b)                                 Except for any Guarantor whose Guarantee is to be released in accordance with this Supplemental Indenture in connection with a transaction complying with Section 9.04, each Guarantor will not, and the Company will not permit a Guarantor to, in a Transaction, (x) consolidate with or merge with or into any other Person (other than the Company or any other Guarantor) or (y) sell, assign, convey, transfer, lease or otherwise dispose of all or substantially all of its properties and assets to any Person (other than the Company or any other Guarantor), unless at the time and after giving effect thereto:

(1)                                 one of the following is true: (a) a Guarantor or the Company will be the continuing Person in the case of a consolidation or merger involving the Guarantor; or (b) the Person (if other than a Guarantor or the Company) formed by such consolidation or into which such Guarantor is merged or the Person (if other than a Guarantor or the Company) which acquires by sale, assignment, conveyance, transfer, lease or disposition of all or substantially all of the properties and assets of the Guarantor (the “Surviving Guarantor Entity”) will be a corporation, limited liability company,

86

limited liability partnership, partnership, trust or other entity duly organized and validly existing under the laws of the United States of America, any state thereof or the District of Columbia and such Person expressly assumes, by a supplemental indenture, in a form reasonably satisfactory to the Trustee, all the obligations of such Guarantor under its Guarantee of the Notes, the Base Indenture (as it relates to the Notes) and this Supplemental Indenture, and such Guarantee of such Surviving Guarantor Entity and the Indenture will remain in full force and effect; or (c) the Transaction, at the time thereof, is an Asset Sale and is effected in compliance with Section 4.11, to the extent applicable thereto;

(2)                                 immediately before and immediately after giving effect to such transaction on a pro forma basis, no Default or Event of Default will have occurred and be continuing; and

(3)                                 at the time of the transaction the Company will have delivered, or caused to be delivered, to the Trustee an Officers’ Certificate and an Opinion of Counsel, each to the effect that such consolidation, merger, transfer, sale, assignment, conveyance, lease or other transaction and the supplemental indenture in respect thereof comply with this Supplemental Indenture and the Base Indenture (as it relates to the Notes);

provided that this Section 5.01(b) shall not apply to any Guarantor whose Guarantee of the Notes is unconditionally released and discharged in accordance with this Supplemental Indenture and the Base Indenture (as it relates to the Notes).

(c)                                  In the event of any Transaction described in and complying with the conditions listed in paragraph (a) or (b) of this Section 5.01 in which the Company or any Guarantor, as the case may be, is not the continuing Person, the successor Person formed or remaining or to which such transfer is made shall succeed to, and be substituted for, and may exercise every right and power of, the Company or such Guarantor, as the case may be, under the Base Indenture (as it relates to the Notes), this Supplemental Indenture and the Notes with the same effect as if such successor had been named as the Company or such Guarantor, as the case may be, herein and shall be substituted for the Company or such Guarantor, as the case may be (so that from and after the date of such Transaction, the provisions of the Base Indenture (as it relates to the Notes), this Supplemental Indenture and the Notes referring to the “Company” or “such Guarantor,” as the case may be, shall refer instead to the successor and not to the Company or such Guarantor, as the case may be) and (except in the case of a lease) the Company or such Guarantor, as the case may be, shall be discharged and released from all obligations and covenants under the Base Indenture (as it relates to the Notes), this Supplemental Indenture and the Notes or its Guarantee, as the case may be.  The Trustee shall enter into a supplemental indenture to evidence the succession and substitution of such successor and such discharge and release of the Company or such Guarantor, as the case may be.

(d)                                 Notwithstanding paragraphs (a) and (b) of this Section 5.01, the Company or any Guarantor may merge with an Affiliate incorporated or organized solely for the purpose of reincorporating or reorganizing the Company or such Guarantor in another jurisdiction to realize tax or other benefits or converting the Company or such Guarantor to an entity that is, or is taxable for federal income tax purposes as, a corporation, or a combination of the foregoing.

88

giving of any applicable notice and the expiration of any applicable grace period and shall not have been cured or waived and, if not already matured at its final maturity in accordance with its terms, the holder of such Indebtedness shall have the right to accelerate such Indebtedness or (b) an event of default as defined in any of the agreements, indentures or instruments described in clause (a) of this clause (5) shall have occurred and the Indebtedness thereunder, if not already matured at its final maturity in accordance with its terms, shall have been accelerated;

(6)                                 any Guarantee shall for any reason cease to be, or shall for any reason be asserted in writing by any Guarantor or the Company not to be, in full force and effect and enforceable in accordance with its terms, except to the extent contemplated by this Supplemental Indenture and any such Guarantee;

(7)                                 one or more judgments, orders or decrees of any court or regulatory or administrative agency for the payment of money in excess of $20.0 million (excluding amounts covered by enforceable insurance policies issued by solvent insurance carriers), either individually or in the aggregate, shall be rendered against the Company, any Guarantor or any other Significant Subsidiary or any of their respective properties and shall not be discharged and either (a) any creditor shall have commenced an enforcement proceeding in accordance with applicable law upon such judgment, order or decree or (b) there shall have been a period of 60 consecutive days during which a stay of enforcement of such judgment or order, by reason of an appeal or otherwise, shall not be in effect;

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.

89

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) 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.  Thereupon, the Trustee may, at its discretion, proceed to protect and enforce the rights of the Holders 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 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.

90

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 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 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 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 1.11, 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 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 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.

91

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;

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 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 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

94

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, Sections 6.01(3) through (7) shall not constitute Events of Default.

(b)                                 in the case of Legal Defeasance, the Company shall have delivered to the Trustee an opinion of independent counsel in the United States stating that (A) the Company has received from, or there has been published by, the Internal Revenue Service a ruling or (B) since the Issue Date, there has been a change in the applicable federal income tax law, in either case to the effect that, and based thereon such opinion of independent counsel in the United States shall confirm 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 Legal Defeasance and will be subject to federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Legal Defeasance had not occurred;

95

(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 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.

(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.

96

(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, shall, 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.
