REDEMPTION AND PREPAYMENT

Section 3.01 Notices to Trustee.

If the Company elects to redeem Notes pursuant to the optional redemption provisions of Section 3.07 hereof, it must furnish to the Trustee, at least 30 days (45 days in the case of a partial redemption) but not more than 60 days before a redemption date, an Officer’s Certificate setting forth:

(1) the clause of this Supplemental Indenture pursuant to which the redemption shall occur;

(2) the redemption date;

(3) the principal amount of Notes to be redeemed; and

(4) the redemption price.

Section 3.02 Selection of Notes to Be Redeemed or Purchased.

If less than all of the Notes are to be redeemed at any time, the Trustee shall select Notes for redemption on a pro rata basis among all outstanding Notes or, if the Notes are listed on any national securities exchange, in compliance with the requirements of the principal national securities exchange on which the Notes are listed, in either case, unless otherwise required by law.

In the event of partial redemption by lot, the particular Notes to be redeemed or purchased shall be selected, unless otherwise provided herein, not less than 30 nor more than 60 days prior to the redemption by the Trustee from the outstanding Notes not previously called for redemption.

The Trustee shall promptly notify the Company in writing of the Notes selected for redemption and, in the case of any Note selected for partial redemption, the principal amount thereof to be redeemed. Notes and portions of Notes selected shall be in amounts of $5,000 or whole multiples of $5,000 in excess of $5,000; except that if all of the Notes of a Holder are to be redeemed, the entire outstanding amount of Notes held by such Holder, even if not a multiple of $5,000, shall be redeemed. Except as provided in the preceding sentence, provisions of this Supplemental Indenture that apply to Notes called for redemption also apply to portions of Notes called for redemption.

No Notes of $5,000 or less shall be redeemed in part. Notices of redemption shall be mailed by first class mail at least 30 but not more than 60 days before the redemption date to each Holder of Notes to be redeemed at its registered address, except that redemption notices may be mailed more than 60 days prior to a redemption date if the notice is issued in connection with a defeasance of the Notes or a satisfaction and discharge of this Supplemental Indenture.

If any Note is to be redeemed in part only, the notice of redemption that relates to that Note shall state the portion of the principal amount of that Note that is to be redeemed. A new Note in principal amount equal to the unredeemed portion of the original Note shall be issued in the name of the Holder of notes upon cancellation of the original Note. Notes called for redemption become due on the date fixed for redemption. On and after the redemption date, interest ceases to accrue on notes or portions of them called for redemption.

Section 3.03 Notice of Redemption.

At least 30 days but not more than 60 days before a redemption date, the Company shall mail or cause to be mailed, by first class mail, a notice of redemption to each Holder whose Notes are to be redeemed at its registered address, except that redemption notices may be mailed more than 60 days prior to a redemption date if the notice is issued in connection with a defeasance of the Notes or a satisfaction and discharge of this Supplemental Indenture pursuant to Article 8 or 11 of this Supplemental Indenture.

The notice will identify the Notes to be redeemed and will state:

(1) the redemption date;

(2) the redemption price;

(3) 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 unredeemed portion will be issued upon cancellation of the original Note;

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

(5) that Notes called for redemption must be surrendered to the Paying Agent to collect the redemption price;

(6) that, unless the Company defaults in making such redemption payment, interest on Notes called for redemption ceases to accrue on and after the redemption date;

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

(8) that no representation is made as to the correctness or accuracy of the CUSIP number, if any, listed in such notice or printed on the Notes.

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 has delivered to the Trustee, at least 45 days prior to the redemption date (or such shorter period as the Trustee in its sole discretion may allow), an Officer’s Certificate requesting that the Trustee give such notice and setting forth the information to be stated in such notice as provided in the preceding paragraph.

Section 3.04 Effect of Notice of Redemption.

Once notice of redemption is mailed in accordance with Section 3.03 hereof, Notes called for redemption become irrevocably due and payable on the redemption date at the redemption price. A notice of redemption may not be conditional.

Section 3.05 Deposit of Redemption or Purchase Price.

One Business Day prior to the redemption or Purchase Date, the Company shall deposit with the Trustee or with the Paying Agent money sufficient to pay the redemption or purchase price of, accrued interest, and premium, if any, on all Notes to be redeemed or purchased on that date. Promptly after the Company’s written request, 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 of the amounts necessary to pay the redemption or purchase price of, accrued interest, and premium, if any, on, all Notes to be redeemed or purchased.

If the Company complies with the provisions of the preceding paragraph, on and after the redemption or Purchase Date, interest will cease to accrue on the Notes or the portions of Notes called for redemption or purchase. If a Note is redeemed or purchased 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 Person in whose name such Note was registered at the close of business on such record date. If any Note called for redemption or purchase is not so paid upon surrender for redemption or purchase because of the failure of the Company to comply with the preceding paragraph, interest shall be paid on the unpaid principal, from the redemption or purchase 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 hereof.

Section 3.06 Notes Redeemed or Purchased in Part.

Upon surrender of a Note that is redeemed or purchased in part, the Company shall issue and, upon receipt of a Company Order, the Trustee shall authenticate for the Holder at the expense of the Company a new Note equal in principal amount to the unredeemed or unpurchased portion of the Note surrendered.

Section 3.07 Optional Redemption.

(a) At any time prior to January 15, 2012, the Company may on any one or more occasions redeem up to 35% of the aggregate principal amount of the Notes issued under this Supplemental Indenture, upon not less than 30 nor more than 60 days’ notice, at a redemption price of 107.375% of the

principal amount, plus accrued and unpaid interest to the redemption date, with the proceeds of one or more Equity Offerings; provided that:

(1) at least 65% of the aggregate principal amount of the Notes issued under this Supplemental Indenture (excluding Notes held by the Company and its Subsidiaries) remains outstanding immediately after the occurrence of such redemption; and

(2) the redemption occurs within 90 days of the date of the closing of such Equity Offering.

(b) At any time prior to January 15, 2012, the Company may on any one or more occasions redeem all or a part of the Notes, upon not less than 30 nor more than 60 days’ prior notice, at a redemption price equal to 100% of the principal amount of Notes redeemed plus the Applicable Premium as of, and accrued and unpaid interest if any, to the redemption date, subject to the rights of Holders of Notes on the relevant record date to receive interest due on the relevant interest payment date.

(c) Except pursuant to clauses (a) and (b) above, the Notes are not redeemable at the Company’s option prior to January 15, 2012. The Company is not prohibited, however, from acquiring the notes in market transactions by means other than a redemption, whether pursuant to a tender offer or otherwise, assuming such action does not otherwise violate the Indenture.

(d) On or after January 15, 2012, the Company may on any one or more occasions redeem all or a part of the Notes upon not less than 30 nor more than 60 days’ notice, at the redemption prices (expressed as percentages of principal amount) set forth below plus accrued and unpaid interest on the Notes redeemed, to the applicable redemption date, if redeemed during the twelve-month period beginning on February 1 of the years indicated below, subject to the rights of Holders on the relevant record date to receive interest on the relevant interest payment date:

(e) Any redemption pursuant to this Section 3.07 shall be made pursuant to the provisions of Section 3.01 through 3.06 hereof.

Section 3.08 Mandatory Redemption.

Except as required in Section 3.09 hereof, the Company is not required to make mandatory redemption or sinking fund payments with respect to the Notes.

Section 3.09 Offer to Purchase by Application of Excess Proceeds.

In the event that, pursuant to Section 4.10 hereof, the Company is required to commence an Asset Sale Offer, it shall follow the procedures specified below.

The Asset Sale Offer shall be made to all Holders of Notes and all holders of other Indebtedness that is pari passu with the Notes containing provisions similar to those set forth in this Supplemental Indenture with respect to offers to purchase or redeem with the proceeds of sales of assets. The Asset Sale Offer shall remain open for a period of at least 20 Business Days following its commencement and

not more than 30 Business Days, except to the extent that a longer period is required by applicable law (the “Offer Period”). No later than three Business Days after the termination of the Offer Period (the “Purchase Date”), the Company shall apply all Excess Proceeds (the “Offer Amount”) to the purchase of Notes and such other pari passu Indebtedness (on a pro rata basis, if applicable) or, if less than the Offer Amount has been tendered, all Notes and other Indebtedness tendered in response to the Asset Sale Offer. Payment for any Notes so purchased shall be made in the same manner as interest payments are made.

If the Purchase Date is on or after an interest record date and on or before the related interest payment date, any accrued and unpaid interest shall be paid to the Person in whose name a Note is registered at the close of business on such record date, and no additional interest will be payable to Holders who tender Notes pursuant to the Asset Sale Offer.

Upon the commencement of an Asset Sale Offer, the Company shall send, by first class mail, a notice to the Trustee and each of the Holders. The notice will contain all instructions and materials necessary to enable such Holders to tender Notes pursuant to the Asset Sale Offer. The notice, which will govern the terms of the Asset Sale Offer, will state:

(1) that the Asset Sale Offer is being made pursuant to this Section 3.09 and Section 4.10 hereof and the length of time the Asset Sale Offer will remain open;

(2) the Offer Amount, the purchase price and the Purchase Date;

(3) that any Note not tendered or accepted for payment will continue to accrue interest;

(4) that, unless the Company defaults in making such payment, any Note accepted for payment pursuant to the Asset Sale Offer shall cease to accrue interest after the Purchase Date;

(5) that Holders electing to have a Note purchased pursuant to an Asset Sale Offer may elect to have Notes purchased in denominations of $5,000, or integral multiples of $5,000 in excess of $5,000;

(6) that Holders electing to have a Note purchased pursuant to any Asset Sale Offer shall be required to surrender the Note, with the form entitled “Option of Holder to Elect Purchase” on the reverse of the Note completed, or transfer by book-entry transfer, to the Company, a Depositary, if appointed by the Company, or a Paying Agent at the address specified in the notice at least three days before the Purchase Date;

(7) that Holders shall be entitled to withdraw their election if the Company, the Depositary or the Paying Agent, as the case may be, receives, not later than the expiration of the Offer Period, a telegram, telex, facsimile transmission or letter setting forth the name of the Holder, the principal amount of the Note the Holder delivered for purchase and a statement that such Holder is withdrawing his election to have such Note purchased;

(8) that, if the aggregate principal amount of Notes and other pari passu Indebtedness surrendered in connection with the Asset Sale Offer exceeds the Offer Amount, the Company shall select the Notes and other pari passu Indebtedness to be purchased on a pro rata basis based on the principal amount of Notes and such other pari passu Indebtedness surrendered (with such adjustments as may be deemed appropriate by the Company so that only Notes in denominations of $5,000, or integral multiples of $5,000 in excess of $5,000, will be purchased); and

(9) that Holders whose Notes were purchased only in part will be issued new Notes equal in principal amount to the unpurchased portion of the Notes surrendered (or transferred by book-entry transfer).

On or before the Purchase Date, the Company shall, to the extent lawful, accept for payment, on a pro rata basis to the extent necessary, the Offer Amount of Notes or portions thereof tendered pursuant to the Asset Sale Offer, or if less than the Offer Amount has been tendered, all Notes tendered, and shall deliver to the Trustee an Officer’s Certificate stating that such Notes or portions thereof were accepted for payment by the Company in accordance with the terms of this Section 3.09. The Company, the Depositary or the Paying Agent, as the case may be, shall promptly (but in any case not later than five days after the Purchase Date) mail or deliver to each tendering Holder an amount equal to the purchase price of the Notes tendered by such Holder and accepted by the Company for purchase, and the Company shall promptly issue a new Note, and the Trustee, upon written request from the Company shall authenticate and mail or deliver such new Note to such Holder, in a principal amount equal to any unpurchased portion of the Note surrendered. Any Note not so accepted shall be promptly mailed or delivered by the Company to the Holder thereof. The Company shall publicly announce the results of the Asset Sale Offer on or as soon as practicable after the Purchase Date.

Other than as specifically provided in this Section 3.09, any purchase pursuant to this Section 3.09 shall be made pursuant to the provisions of Sections 3.01 through 3.06 hereof.

The Company may also from time to time designate one or more other offices or agencies where the Notes may be presented or surrendered for any or all such purposes and may from time to time rescind such designations; provided, however, that no such designation or rescission will in any manner relieve the Company of its obligation to maintain an office or agency in the Borough of Manhattan, the City of New York for such purposes. The Company shall give prompt written notice to the Trustee of any such designation or rescission and of any change in the location of any such other office or agency.

If, at any time, the Company is no longer subject to the periodic reporting requirements of the Exchange Act for any reason, the Company shall nevertheless continue filing the reports specified in this Section 4.03(a) with the SEC within the time periods specified above unless the SEC will not accept such a filing. The Company agrees that it shall not take any action for the purpose of causing the SEC not to accept any such filings.

The Company’s fiscal year ends December 31st.

(b) So long as any of the Notes are outstanding, the Company shall deliver to the Trustee, forthwith upon any Officer becoming aware of any Default or Event of Default, an Officer’s Certificate specifying such Default or Event of Default and what action the Company is taking or proposes to take with respect thereto.

(3) such Restricted Payment, together with the aggregate amount of all other Restricted Payments made by the Company and its Restricted Subsidiaries since January 1, 2006 (excluding Restricted Payments permitted by clauses (2), (3), (4), (6), (7), (8), (9), (10), (11), and (12) of Section 4.07(b) hereof), is less than the sum, without duplication, of:

case, that the foregoing may not exceed, in the aggregate, the amount of all Investments which previously reduced the ability to make Restricted Payments; and provided further, that Concurrent Cash Distributions shall be excluded from this clause (C).

(10) so long as no Default has occurred and is continuing or would be caused thereby, upon the occurrence of a Change of Control or Asset Sale and after the completion of the offer to repurchase the Notes as described in Sections 4.10 and 4.14 hereof (including the purchase of all Notes tendered), any purchase, defeasance, retirement, redemption or other acquisition of Indebtedness that is contractually subordinated to the Notes or any subsidiary guarantee required under the terms of such Indebtedness, with, in the case of an Asset Sale, Net Proceeds, as a result of such Change of Control or Asset Sale;

Section 4.08 Dividend and Other Payment Restrictions Affecting Subsidiaries.

(a) The Company shall not, and shall not permit any of its Restricted Subsidiaries (other than Excluded Subsidiaries) to, directly or indirectly, create or permit to exist or become effective any consensual encumbrance or restriction on the ability of any Restricted Subsidiary (other than an Excluded Subsidiary) to:

(1) pay dividends or make any other distributions on its Capital Stock to the Company or any of its Restricted Subsidiaries (other than Excluded Subsidiaries), or with respect to any other interest or participation in, or measured by, its profits, or pay any indebtedness owed to the Company or any of its Restricted Subsidiaries (other than Excluded Subsidiaries);

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

(8) Liens permitted to be incurred under Section 4.12 hereof and associated agreements that limit the right of the debtor to dispose of the assets subject to such Liens;

(9) provisions limiting the disposition or distribution of assets or property in joint venture, partnership, membership, stockholder and limited liability company agreements, asset sale agreements, sale-leaseback agreements, stock sale agreements and other similar agreements, including owners’, participation or similar agreements governing projects owned through an undivided interest, which limitation is applicable only to the assets that are the subject of such agreements;

(10) restrictions on cash or other deposits or net worth imposed by customers under contracts entered into in connection with a Permitted Business;

(11) restrictions or conditions contained in any trading, netting, operating, construction, service, supply, purchase, sale or similar agreement to which the Company or any Restricted Subsidiary of the Company is a party entered into in connection with a Permitted Business; provided that such agreement prohibits the encumbrance of solely the property or assets of the Company or such Restricted Subsidiary that are the subject of that agreement, the payment rights arising thereunder and/or the proceeds thereof and not to any other asset or property of the Company or such Restricted Subsidiary or the assets or property of any other Restricted Subsidiary;

(12) any instrument governing Indebtedness or Capital Stock of a Person acquired by the Company or any of its Restricted Subsidiaries as in effect at the time of such acquisition (except to the extent such Indebtedness or Capital Stock was incurred in connection with or in contemplation of such acquisition), which encumbrance or restriction is not applicable to any Person, or the properties or assets of any Person, other than the Person, or the property or assets of the Person, so acquired; provided that, in the case of Indebtedness, such Indebtedness was permitted by the terms of this Supplemental Indenture to be incurred;

(13) Indebtedness of a Restricted Subsidiary of the Company existing at the time it became a Restricted Subsidiary if such restriction was not created in connection with or in anticipation of the transaction or series of transactions pursuant to which such Restricted Subsidiary became a Restricted Subsidiary or was acquired by the Company;

(14) with respect only to Section 4.08(a)(3) hereof, restrictions encumbering property at the time such property was acquired by the Company or any of its Restricted Subsidiaries, so long as such restriction relates solely to the property so acquired and was not created in connection with or in anticipation of such acquisition;

(15) provisions limiting the disposition or distribution of assets or property in agreements governing Non-Recourse Debt, which limitation is applicable only to the assets that are the subject of such agreements; and

(16) any encumbrance or restrictions of the type referred to in clauses (1), (2) and (3) of Section 4.08(a) hereof imposed by any amendments, modifications, restatements, renewals, increases, supplements, refundings, replacements or refinancings of the contracts, instruments or obligations referred to in clauses (1) through (15) above; provided that such amendments, modifications, restatements, renewals, increases, supplements, refundings, replacements or refinancings are, in the good faith judgment of a senior financial officer of the Company, no more restrictive with respect to such dividend and other payment restrictions than those contained in the dividend or other payment restrictions prior to such amendment, modification, restatement, renewals, increase, supplement, refunding, replacement or refinancing.

Section 4.09 Incurrence of Indebtedness and Issuance of Preferred Stock.

(a) The Company shall not, and shall not permit any of its Restricted Subsidiaries to, directly or indirectly, create, incur, issue, assume, guarantee or otherwise become directly or indirectly liable, contingently or otherwise, with respect to (collectively, “incur”) any Indebtedness (including Acquired Debt), and the Company shall not issue any Disqualified Stock and shall not permit any of its Restricted Subsidiaries to issue any shares of preferred stock; provided, however, that the Company may incur Indebtedness (including Acquired Debt) or issue Disqualified Stock, and the Guarantors may incur Indebtedness (including Acquired Debt) or issue preferred stock, if the Fixed Charge Coverage Ratio for the Company’s most recently ended four full fiscal quarters for which internal financial statements are

publicly available immediately preceding the date on which such additional Indebtedness is incurred or such Disqualified Stock or preferred stock is issued would have been at least 2.0 to 1, determined on a pro forma basis (including a pro forma application of the net proceeds therefrom), as if the additional Indebtedness (including Acquired Debt) had been incurred or the Disqualified Stock or preferred stock had been issued, as the case may be, at the beginning of such four-quarter period.

(b) The provisions of Section 4.09(a) shall not prohibit the incurrence of any of the following items of Indebtedness (collectively, “Permitted Debt”):

(1) the incurrence by the Company and PMI (and the guarantee thereof by the Guarantors) of additional Indebtedness and letters of credit under Credit Facilities in an aggregate principal amount at any one time outstanding under this clause (1) (with letters of credit being deemed to have a principal amount equal to the maximum potential liability of the Company and its Restricted Subsidiaries thereunder) not to exceed $6.0 billion less the aggregate amount of all repayments, optional or mandatory, of the principal of any term Indebtedness under a Credit Facility that have been made by the Company or any of its Restricted Subsidiaries since February 2, 2006 with the Net Proceeds of Asset Sales (other than Excluded Proceeds) and less, without duplication, the aggregate amount of all repayments or commitment reductions with respect to any revolving credit borrowings under a Credit Facility that have been made by the Company or any of its Restricted Subsidiaries since February 2, 2006 as a result of the application of the Net Proceeds of Asset Sales (other than Excluded Proceeds) in accordance with Section 4.10 hereof (excluding temporary reductions in revolving credit borrowings as contemplated by that covenant);

(2) the incurrence by the Company and its Restricted Subsidiaries of the Existing Indebtedness;

(3) the incurrence by the Company and the Guarantors of Indebtedness represented by the Notes and the related Subsidiary Guarantees to be issued on the date of this Supplemental Indenture;

(4) the incurrence by the Company or any of its Restricted Subsidiaries of Indebtedness represented by Capital Lease Obligations, mortgage financings or purchase money obligations, in each case, incurred for the purpose of financing all or any part of the purchase price or cost of design, construction, installation or improvement or lease of property (real or personal), plant or equipment used or useful in the business of the Company or any of its Restricted Subsidiaries or incurred within 180 days thereafter, in an aggregate principal amount, including all Permitted Refinancing Indebtedness incurred to refund, refinance, replace, defease or discharge any Indebtedness incurred pursuant to this clause (4), not to exceed at any time outstanding 5.0% of Total Assets;

(5) the incurrence by the Company or any of its Restricted Subsidiaries of Permitted Refinancing Indebtedness in exchange for, or the net proceeds of which are used to refund, refinance, replace, defease or discharge Indebtedness (other than intercompany Indebtedness) that was permitted by this Supplemental Indenture to be incurred under Section 4.09(a) hereof or clauses (2), (3), (4), (5), (15), (16), (17), (18), and (19) of this paragraph;

(6) the incurrence by the Company or any of its Restricted Subsidiaries of intercompany Indebtedness between or among the Company and any of its Restricted Subsidiaries; provided, however, that:

(A) if the Company or any Guarantor is the obligor on such Indebtedness and the payee is not the Company or a Guarantor, such Indebtedness must be expressly subordinated to the prior payment in full in cash of all Obligations then due with respect to the Notes, in the case of the Company, or the Subsidiary Guarantee, in the case of a Guarantor; and

(B) (i) any subsequent issuance or transfer of Equity Interests that results in any such Indebtedness being held by a Person other than the Company or a Restricted Subsidiary of the Company and (ii) any sale or other transfer of any such Indebtedness to a Person that is not either the Company or a Restricted Subsidiary of the Company;

will 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 (6);

(7) the issuance by any of the Company’s Restricted Subsidiaries to the Company or to any of its Restricted Subsidiaries of shares of preferred stock; provided, however, that:

(A) any subsequent issuance or transfer of Equity Interests that results in any such preferred stock being held by a Person other than the Company or a Restricted Subsidiary of the Company; and

(B) any sale or other transfer of any such preferred stock to a Person that is not either the Company or a Restricted Subsidiary of the Company;

will be deemed, in each case, to constitute an issuance of such preferred stock by such Restricted Subsidiary that was not permitted by this clause (7);

(8) the incurrence by the Company or any of its Restricted Subsidiaries of Hedging Obligations;

(9) the guarantee by (i) the Company or any of the Guarantors of Indebtedness of the Company or a Guarantor that was permitted to be incurred by another provision of this covenant; (ii) any of the Excluded Project Subsidiaries of Indebtedness of any other Excluded Project Subsidiary; and (iii) any of the Excluded Foreign Subsidiaries of Indebtedness of any other Excluded Foreign Subsidiary; provided that if the Indebtedness being guaranteed is subordinated to or pari passu with the Notes, then the guarantee shall be subordinated to the same extent as the Indebtedness guaranteed;

(10) the incurrence by the Company or any of its Restricted Subsidiaries of Indebtedness arising from the honoring by a bank or other financial institution of a check, draft or similar instrument (except in the case of daylight overdrafts) inadvertently drawn against insufficient funds in the ordinary course of business, so long as such Indebtedness is covered within five business days;

(11) the incurrence by the Company or any of its Restricted Subsidiaries of Indebtedness in respect of (i) workers’ compensation claims, self-insurance obligations, bankers’ acceptance and (ii) performance and surety bonds provided by the Company or a Restricted Subsidiary in the ordinary course of business;

(12) (i) the incurrence of Non-Recourse Debt by any Excluded Project Subsidiary, and (ii) the incurrence of Indebtedness and guarantees pursuant to the Itiquira Refinancing;

(13) the incurrence of Indebtedness that may be deemed to arise as a result of agreements of the Company or any Restricted Subsidiary of the Company providing for indemnification, adjustment of purchase price or any similar obligations, in each case, incurred in connection with the disposition of any business, assets or Equity Interests of any Subsidiary; provided that the aggregate maximum liability associated with such provisions may not exceed the gross proceeds (including non-cash proceeds) of such disposition;

(14) the incurrence by the Company or any Restricted Subsidiary of the Company of Indebtedness represented by letters of credit, guarantees or other similar instruments supporting Hedging Obligations of the Company or any of its Restricted Subsidiaries (other than Excluded Subsidiaries) permitted to be incurred by this Supplemental Indenture;

(15) Indebtedness, Disqualified Stock or preferred stock of Persons or assets that are acquired by the Company or any Restricted Subsidiary of the Company or merged into the Company or a Restricted Subsidiary of the Company in accordance with the terms of this Supplemental Indenture; provided that such Indebtedness, Disqualified Stock or preferred stock is not incurred in contemplation of such acquisition or merger; and provided further that after giving effect to such acquisition or merger, either:

(A) the Company would be permitted to incur at least $1.00 of additional Indebtedness pursuant to the Fixed Charge Coverage Ratio test set forth in the first sentence of Section 4.09(a) hereof; or

(B) the Fixed Charge Coverage Ratio would be greater than immediately prior to such acquisition or merger;

(16) Environmental CapEx Debt; provided, that prior to the incurrence of any Environmental CapEx Debt, the Company shall deliver to the Trustee an Officers’ Certificate designating such Indebtedness as Environmental CapEx Debt;

(17) Indebtedness incurred to finance Necessary Capital Expenditures; provided, that prior to the incurrence of any Indebtedness to finance Necessary Capital Expenditures, the Company shall deliver to the Trustee an Officers’ Certificate designating such Indebtedness as Necessary CapEx Debt;

(18) Indebtedness of the Company or any Restricted Subsidiary of the Company consisting of (i) the financing of insurance premiums or (ii) take-or-pay obligations contained in supply arrangements, in each case, in the ordinary course of business; and

(19) the incurrence by the Company and/or any of its Restricted Subsidiaries of additional Indebtedness in an aggregate principal amount (or accreted value, as applicable) at any time outstanding, including all Permitted Refinancing Indebtedness incurred to refund, refinance, replace, defease or discharge any Indebtedness incurred pursuant to this clause (19), not to exceed $500.0 million.

The Company shall not, and shall not permit any Guarantor to, incur any Indebtedness (including Permitted Debt) that is contractually subordinated in right of payment to any other Indebtedness of the Company or that Guarantor unless such Indebtedness is also contractually subordinated in right of

payment to the Notes and the applicable Subsidiary Guarantee on substantially identical terms; provided, however, that no Indebtedness of the Company shall be deemed to be contractually subordinated in right of payment to any other Indebtedness of the Company solely by virtue of being unsecured or by virtue of being secured on a first or junior Lien basis.

For purposes of determining compliance with this Section 4.09, in the event that an item of proposed Indebtedness meets the criteria of more than one of the categories of Permitted Debt described in clauses (1) through (19) above, or is entitled to be incurred pursuant to Section 4.09(a) hereof, the Company shall be permitted to classify such item of Indebtedness on the date of its incurrence, or later reclassify all or a portion of such item of Indebtedness, in any manner that complies with this Section 4.09. Indebtedness under the Credit Agreement outstanding on the date of the Supplemental Indenture will initially be deemed to have been incurred on such date in reliance on the exception provided by clause (1) above. The accrual of interest, the accretion or amortization of original issue discount, the payment of interest on any Indebtedness in the form of additional Indebtedness with the same terms, and the payment of dividends on Disqualified Stock in the form of additional shares of the same class of Disqualified Stock shall not be deemed to be an incurrence of Indebtedness or an issuance of Disqualified Stock for purposes of this Section 4.09; provided, in each such case, that the amount thereof is included in Fixed Charges of the Company as accrued.

For purposes of determining compliance with any U.S. dollar-denominated restriction on the incurrence of Indebtedness, the U.S. dollar-equivalent principal amount of Indebtedness denominated in a foreign currency will be calculated based on the relevant currency exchange rate in effect on the date such Indebtedness was incurred; provided that if such Indebtedness is incurred to refinance other Indebtedness denominated in a foreign currency, and such refinancing would cause the applicable U.S. dollar-dominated restriction to be exceeded if calculated at the relevant currency exchange rate in effect on the date of such refinancing, such U.S. dollar-dominated restriction shall be deemed not to have been exceeded so long as the principal amount of such refinancing Indebtedness does not exceed the principal amount of the Indebtedness being refinanced.

The amount of any Indebtedness outstanding as of any date will be:

(1) the accreted value of the Indebtedness, in the case of any Indebtedness issued with original issue discount;

(2) the principal amount of the Indebtedness, in the case of any other Indebtedness; and

(3) in respect of Indebtedness of another Person secured by a Lien on the assets of the specified Person, the lesser of:

(A) the fair market value of such asset at the date of determination, and

(B) the amount of the Indebtedness of the other Person;

provided that any changes in any of the above shall not give rise to a default under this Section 4.09.

Section 4.10 Asset Sales.

(a) The Company shall not, and shall not permit any of its Restricted Subsidiaries to, consummate an Asset Sale unless:

(1) the Company (or the Restricted Subsidiary, as the case may be) receives consideration at the time of the Asset Sale at least equal to the fair market value of the assets or Equity Interests issued or sold or otherwise disposed of; and

(2) at least 75% of the consideration received in the Asset Sale by the Company or such Restricted Subsidiary is in the form of cash. For purposes of this provision, each of the following will be deemed to be cash:

(A) any liabilities, as shown on the Company’s most recent consolidated balance sheet, of the Company or any Restricted Subsidiary (other than contingent liabilities and liabilities that are by their terms subordinated to the Notes or any Subsidiary Guarantee) that are assumed by the transferee of any such assets pursuant to a customary novation agreement that releases the Company or such Restricted Subsidiary from further liability;

(B) any securities, notes or other obligations received by the Company or any such Restricted Subsidiary from such transferee that are converted by the Company or such Restricted Subsidiary into cash within 180 days of the receipt of such securities, notes or other obligations, to the extent of the cash received in that conversion;

(D) any Designated Noncash Consideration received by the Company or any Restricted Subsidiary of the Company in such Asset Sale having an aggregate fair market value, taken together with all other Designated Noncash Consideration received pursuant to this clause (D) and Section 4.10(a)(2)(D) of the First Supplemental Indenture that is at the time outstanding, not to exceed the greater of (x) $500.0 million or (y) 2.5% of Total Assets at the time of the receipt of such Designated Noncash Consideration, with the fair market value of each item of Designated Noncash Consideration being measured at the time received and without giving effect to subsequent changes in value.

(b) Within 365 days after the receipt of any Net Proceeds from an Asset Sale, other than Excluded Proceeds, the Company (or the applicable Restricted Subsidiary, as the case may be) may apply such Net Proceeds or, at its option, enter into a binding commitment to apply such Net Proceeds within the 365-day period following the date of such commitment (an “Acceptable Commitment”):

(1) to repay Indebtedness and other Obligations under a Credit Facility and, if such Indebtedness is revolving credit Indebtedness, to correspondingly reduce commitments with respect thereto;

(2) in the case of a sale of assets pledged to secured Indebtedness (including Capital Lease Obligations), to repay the Indebtedness secured by those assets;

(3) in the case of an Asset Sale by a Restricted Subsidiary that is not a Guarantor, to repay Indebtedness of a Restricted Subsidiary that is not a Guarantor (other than Indebtedness owed to the Company or another Restricted Subsidiary of the Company);

(4) to acquire all or substantially all of the assets of, or any Capital Stock of, another Person engaged primarily in a Permitted Business, if, after giving effect to any such acquisition of

Capital Stock, such Person is or becomes a Restricted Subsidiary of the Company and a Guarantor;

(5) to make a capital expenditure;

(6) to acquire other assets that are not classified as current assets under GAAP and that are used or useful in a Permitted Business; or

(7) any combination of the foregoing.

Pending the final application of such Net Proceeds in accordance with this Section 4.10 and notwithstanding clause (1) above, the Company may temporarily reduce revolving credit borrowings or otherwise use the Net Proceeds in any manner that is not prohibited by this Supplemental Indenture.

(c) Notwithstanding the preceding paragraph, in the event that regulatory approval is necessary for an asset or investment, or construction, repair or restoration on any asset or investment has commenced, then the Company or any Restricted Subsidiary shall have an additional 365 days to apply the Net Proceeds from such Asset Sale in accordance with the preceding paragraph.

Any Acceptable Commitment that is later canceled or terminated for any reason before such Net Proceeds are so applied shall be treated as a permitted application of the Net Proceeds if the Company or such Restricted Subsidiary enters into another Acceptable Commitment within the later of (a) nine months of such cancellation or termination or (b) the end of the initial 365-day period.

(d) Any Net Proceeds from Asset Sales (other than Excluded Proceeds) that are not applied or invested as provided in this Section 4.10 shall constitute “Excess Proceeds.” When the aggregate amount of Excess Proceeds exceeds $100.0 million, or at such earlier date as may be selected by the Company, the Company will make an Asset Sale Offer to all Holders of Notes and all holders of other Indebtedness (including Indebtedness evidenced by the Existing Senior Notes) that is pari passu with the Notes containing provisions similar to those set forth in this Supplemental Indenture with respect to offers to purchase or redeem with the proceeds of sales of assets to purchase the maximum principal amount of Notes and such other pari passu Indebtedness that may be purchased out of the Excess Proceeds (an “Asset Sale Offer”). The offer price in any Asset Sale Offer will be equal to 100% of the principal amount plus accrued and unpaid interest to the date of purchase and will be payable in cash. If any Excess Proceeds remain after consummation of an Asset Sale Offer, the Company may use those Excess Proceeds for any purpose not otherwise prohibited by this Supplemental Indenture. If the aggregate principal amount of Notes and other pari passu Indebtedness tendered into such Asset Sale Offer exceeds the amount of Excess Proceeds, the Trustee will select the Notes and such other pari passu Indebtedness to be purchased on a pro rata basis. Upon completion of each Asset Sale Offer, the amount of Excess Proceeds will be reset at zero.

(e) The Company shall comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent such laws and regulations are applicable in connection with each repurchase of Notes pursuant to an Asset Sale Offer. To the extent that the provisions of any securities laws or regulations conflict with the provisions of Sections 3.09 or 4.10 hereof, the Company shall comply with the applicable securities laws and regulations and shall not be deemed to have breached its obligations under Sections 3.09 and 4.10 hereof by virtue of such compliance.

Section 4.11 Transactions with Affiliates.

(a) The Company shall not, and shall not permit any of its Restricted Subsidiaries to, make any payment to, or sell, lease, transfer or otherwise dispose of any of its properties or assets to, or purchase any property or assets from, or enter into or make or amend any transaction, contract, agreement, understanding, loan, advance or guarantee with, or for the benefit of, any Affiliate of the Company (each, an “Affiliate Transaction”) involving aggregate payments in excess of $10.0 million, unless, unless:

(1) the Affiliate Transaction is on terms that are no less favorable to the Company (as reasonably determined by the Company) or the relevant Restricted Subsidiary than those that would have been obtained in a comparable transaction by the Company or such Restricted Subsidiary with an unrelated Person; and

(2) the Company delivers to the Trustee:

(A) with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration in excess of $50.0 million, a resolution of the Board of Directors set forth in an Officers’ Certificate certifying that such Affiliate Transaction complies with this covenant and that such Affiliate Transaction has been approved by a majority of the disinterested members of the Board of Directors; and

(B) with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration in excess of $100.0 million, an opinion as to the fairness to the Company or such Restricted Subsidiary of such Affiliate Transaction from a financial point of view issued by an accounting, appraisal or investment banking firm of national standing.

(b) The following items shall not be deemed to be Affiliate Transactions and, therefore, shall not be subject to the provisions of the prior paragraph:

(1) any employment agreement or director’s engagement agreement, employee benefit plan, officer and director indemnification agreement or any similar arrangement entered into by the Company or any of its Restricted Subsidiaries or approved by the Board of Directors of the Company in good faith;

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

(3) transactions with a Person (other than an Unrestricted Subsidiary of the Company) that is an Affiliate of the Company solely because the Company owns, directly or through a Restricted Subsidiary, an Equity Interest in, or controls, such Person;

(4) payment of directors’ fees;

(5) any issuance of Equity Interests (other than Disqualified Stock) of the Company or its Restricted Subsidiaries;

(6) Restricted Payments that do not violate the provisions of Section 4.07 hereof;

(7) any agreement in effect as of the date of this Supplemental Indenture or any amendment thereto or replacement thereof and any transaction contemplated thereby or permitted thereunder, so long as any such amendment or replacement agreement taken as a whole is not more disadvantageous to the Holders than the original agreement as in effect on the date of this Supplemental Indenture;

(8) payments or advances to employees or consultants that are incurred in the ordinary course of business or that are approved by the Board of Directors of the Company in good faith;

(9) the existence of, or the performance by the Company or any of its Restricted Subsidiaries of its obligations under the terms of, any stockholders agreement (including any registration rights agreement or purchase agreement related thereto) to which it is a party as of the date of this Supplemental Indenture and any similar agreements which it may enter into thereafter; provided, however, that the existence of, or the performance by the Company or any of its Restricted Subsidiaries of obligations under, any future amendment to any such existing agreement or under any similar agreement entered into after the date of this Supplemental Indenture shall only be permitted by this clause (9) to the extent that the terms of any such amendment or new agreement are not otherwise more disadvantageous to the Holders of the Notes in any material respect;

(10) transactions permitted by, and complying with, the provisions of Section 5.01 hereof;

(11) transactions with customers, clients, suppliers, joint venture partners or purchasers or sellers of goods or services (including pursuant to joint venture agreements) otherwise in compliance with the terms of this Supplemental Indenture that are fair to the Company and its Restricted Subsidiaries, in the reasonable determination of a senior financial officer of the Company, or are on terms not materially less favorable taken as a whole as might reasonably have been obtained at such time from an unaffiliated party;

(12) any repurchase, redemption or other retirement of Capital Stock of the Company held by employees of the Company or any of its Subsidiaries;

The Company will not, and will not permit any of its Restricted Subsidiaries to, create, incur, assume or otherwise cause or suffer to exist or become effective any Lien of any kind (other than Permitted Liens) securing Indebtedness or Attributable Debt upon any of their property or assets, now owned or hereafter acquired, unless all payments due under this Supplemental and the Notes are secured

on an equal and ratable basis with the obligations so secured until such time as such obligations are no longer secured by a Lien.

Section 4.13 Corporate Existence.

Subject to Article 5 hereof, the Company shall do or cause to be done all things necessary to preserve and keep in full force and effect:

(1) its corporate existence, and the corporate, partnership or other existence of each of its Subsidiaries, in accordance with the respective organizational documents (as the same may be amended from time to time) of the Company or any such Subsidiary; and

(2) the rights (charter and statutory), licenses and franchises of the Company and its Subsidiaries;

provided, however, that the Company shall not be required to preserve any such right, license or franchise, or the corporate, partnership or other existence of any of its Subsidiaries, if (a) the Company shall determine that the preservation thereof is no longer desirable in the conduct of the business of the Company and its Subsidiaries, taken as a whole, and that the loss thereof is not adverse in any material respect to the Holders of the Notes and (b) if a Subsidiary is to be dissolved, such Subsidiary has no assets.

Section 4.14 Offer to Repurchase Upon Change of Control.

(a) Upon the occurrence of a Change of Control, each Holder of Notes shall have the right to require the Company to make an offer (a “Change of Control Offer”) to each Holder to repurchase all or any part (equal to $5,000 or an integral multiple of $5,000) of each Holder’s Notes at a purchase price equal to 101% of the aggregate principal amount of Notes repurchased plus accrued and unpaid interest on the Notes repurchased, if any, to the date of purchase, subject to the rights of Holders of Notes on the relevant record date to receive interest due on the relevant interest payment date (the “Change of Control Payment”). Within 30 days following any Change of Control, the Company shall mail a notice to each Holder describing the transaction or transactions that constitute the Change of Control and stating:

(1) that the Change of Control Offer is being made pursuant to this Section 4.14 and that all Notes tendered will be accepted for payment;

(2) the purchase price and the purchase date, which date will be no earlier than 30 days and no later than 60 days from the date such notice is mailed (the “Change of Control Payment Date”);

(3) that any Note not tendered will continue to accrue interest;

(4) that, unless the Company defaults in the payment of the Change of Control Payment, all Notes accepted for payment pursuant to the Change of Control Offer will cease to accrue interest after the Change of Control Payment Date;

(5) that Holders electing to have any Notes purchased pursuant to a Change of Control Offer shall be required to surrender the Notes, with the form entitled “Option of Holder to Elect Purchase” on the reverse of the Notes completed, to the Paying Agent at the address specified in the notice prior to the close of business on the third Business Day preceding the Change of Control Payment Date;

(6) that Holders will be entitled to withdraw their election if the Paying Agent receives, not later than the close of business on the second Business Day preceding the Change of Control Payment Date, a telegram, telex, facsimile transmission or letter setting forth the name of the Holder, the principal amount of Notes delivered for purchase, and a statement that such Holder is withdrawing his election to have the Notes purchased; and

(7) that Holders whose Notes are being purchased only in part will be issued new Notes equal in principal amount to the unpurchased portion of the Notes surrendered, which unpurchased portion must be equal to $5,000 in principal amount or an integral multiple of $5,000.

The Company shall comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with the repurchase of the Notes as a result of a Change in Control. To the extent that the provisions of any securities laws or regulations conflict with the provisions of this Section 4.14, the Company shall comply with the applicable securities laws and regulations and shall not be deemed to have breached its obligations under this Section 4.14 by virtue of such compliance.

(b) On the Change of Control Payment Date, the Company shall, to the extent lawful:

(1) accept for payment all Notes or portions of Notes properly tendered pursuant to the Change of Control Offer;

(2) deposit with the Paying Agent an amount equal to the Change of Control Payment in respect of all Notes or portions of Notes properly tendered; and

(3) deliver or cause to be delivered to the Trustee the Notes properly accepted together with an Officer’s Certificate stating the aggregate principal amount of Notes or portions of Notes being purchased by the Company.

The Paying Agent shall promptly mail to each Holder of Notes properly tendered the Change of Control Payment for such Notes, and the Trustee shall promptly authenticate and mail (or cause to be transferred by book entry) to each Holder a new Note equal in principal amount to any unpurchased portion of the Notes surrendered, if any; provided that each new Note shall be in a principal amount of $5,000 or an integral multiple of $5,000. The Company shall publicly announce the results of the Change of Control Offer on or as soon as practicable after the Change of Control Payment Date.

(c) The provisions described in Sections 4.14 (a) and (b) shall apply whether or not other provisions of this Supplemental Indenture are applicable. Except as described in Sections 4.14 (a) and (b) hereof, Holders of Notes shall not be permitted to require that the Company repurchase or redeem the Notes in the event of a takeover, recapitalization or similar transaction.

(d) Notwithstanding anything to the contrary in this Section 4.14, the Company shall not be required to make a Change of Control Offer upon a Change of Control if (1) 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 Section 4.14 hereof and purchases all Notes properly tendered and not withdrawn under the Change of Control Offer, or (2) notice of redemption has been given pursuant to Section 3.07 hereof, unless and until there is a default in payment of the applicable redemption price. A Change of Control Offer may be made in advance of a Change of Control, with the obligation to pay and the timing of payment conditioned upon the consummation of the Change of Control, if a definitive agreement to effect a Change of Control is in place at the time of the Offer.

Section 4.15 Limitation on Sale and Leaseback Transactions.

The Company shall not, and shall not permit any of its Restricted Subsidiaries to, enter into any sale and leaseback transaction; provided that the Company or any Guarantor may enter into a sale and leaseback transaction if:

(1) the Company or that Guarantor, as applicable, could have (a) incurred Indebtedness in an amount equal to the Attributable Debt relating to such sale and leaseback transaction under the provisions of Section 4.09 hereof and (b) incurred a Lien to secure such Indebtedness pursuant to the provisions of Section 4.12 hereof;

(2) the gross proceeds of that sale and leaseback transaction are at least equal to the fair market value of the property that is the subject of that sale and leaseback transaction, as determined in good faith by a senior financial officer of the Company; and

(3) if such sale and leaseback transaction constitutes an Asset Sale, the transfer of assets in that sale and leaseback transaction is permitted by, and the Company applies the proceeds of such transaction in compliance with, the provisions of Section 4.10 hereof.

Section 4.16 Payments for Consent.

The Company shall not, and shall not permit any of its Restricted Subsidiaries to, directly or indirectly, pay or cause to be paid any consideration to or for the benefit of any Holder for or as an inducement to any consent under or waiver or amendment of any of the terms or provisions of the Indenture or the Notes unless such consideration is offered to be paid and 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 Additional Subsidiary Guarantees.

If,

(1) the Company or any of its Restricted Subsidiaries acquires or creates another Domestic Subsidiary (other than an Excluded Subsidiary or a Domestic Subsidiary that does not Guarantee any other Indebtedness of the Company) after the date of this Supplemental Indenture,

(2) any Excluded Subsidiary that is a Domestic Subsidiary ceases to be an Excluded Subsidiary after the date of this Supplemental Indenture, or

(3) any Domestic Subsidiary that does not Guarantee any other Indebtedness of the Company subsequently Guarantees other Indebtedness of the Company,

then such newly acquired or created Subsidiary, former Excluded Subsidiary, or Domestic Subsidiary, as the case may be, will become a Guarantor and execute a supplemental indenture in the form attached hereto as Exhibit C and deliver an Opinion of Counsel satisfactory to the Trustee within 30 business days of the date on which it was acquired or created or ceased to be an Excluded Subsidiary or Guaranteed other Indebtedness of the Company, as the case may be.

Section 4.18 Designation of Restricted, Unrestricted and Excluded Project Subsidiaries.

The Board of Directors may designate any Restricted Subsidiary to be an Unrestricted Subsidiary if that designation would not cause a Default. If a Restricted Subsidiary is designated as an Unrestricted Subsidiary, the aggregate fair market value of all outstanding Investments owned by the Company and its Restricted Subsidiaries in the Subsidiary designated as Unrestricted will be deemed to be an Investment made as of the time of the designation and will reduce the amount available for Restricted Payments under the provisions of Section 4.07 hereof or under one or more clauses of the definition of Permitted Investments, as determined by the Company. That designation will only be permitted if the Investment would be permitted at that time and if the Restricted Subsidiary otherwise meets the definition of an Unrestricted Subsidiary. The Board of Directors may redesignate any Unrestricted Subsidiary to be a Restricted Subsidiary if that redesignation would not cause a Default.

The Board of Directors may designate any Restricted Subsidiary to be an Excluded Project Subsidiary if that designation would not cause a Default. If a Restricted Subsidiary that is not an Excluded Project Subsidiary is designated as an Excluded Project Subsidiary, the aggregate fair market value of all outstanding Investments owned by the Company and its Restricted Subsidiaries in the Subsidiary designated as an Excluded Project Subsidiary will be deemed to be an Investment made as of the time of the designation and will reduce the amount available for Restricted Payments under the provisions of Section 4.07 hereof or under one or more clauses of the definition of Permitted Investments, as determined by the Company. That designation will only be permitted if the Investment would be permitted at that time and if the Restricted Subsidiary otherwise meets the definition of an Excluded Project Subsidiary. The Board of Directors may redesignate any Excluded Project Subsidiary to be a Restricted Subsidiary that is not an Excluded Project Subsidiary if that redesignation would not cause a Default.

Any designation of a Subsidiary of the Company as an Unrestricted Subsidiary or Excluded Project Subsidiary will be evidenced to the Trustee by filing with the Trustee a certified copy of a resolution of the Board of Directors giving effect to such designation and an Officers’ Certificate certifying that such designation complied with the preceding conditions and was permitted by Section 4.07 hereof. If, at any time, any Unrestricted Subsidiary or Excluded Project Subsidiary should fail to meet the preceding requirements as, respectively, an Unrestricted Subsidiary or Excluded Project Subsidiary, it will thereafter cease to be an Unrestricted Subsidiary or Excluded Project Subsidiary for the purposes of this Supplement Indenture and any Indebtedness of such Subsidiary will be deemed to be incurred by a Restricted Subsidiary or an Excluded Project Subsidiary of the Company as of such date and, if such Indebtedness is not permitted to be incurred as of such date under Section 4.09 hereof, the Company will be in default of such covenant. The Board of Directors of the Company may at any time designate any Unrestricted Subsidiary or Excluded Project Subsidiary to be a Restricted Subsidiary; provided that such designation will be deemed to be an incurrence of Indebtedness by a Restricted Subsidiary of the Company of any outstanding Indebtedness of such Unrestricted Subsidiary or Excluded Project Subsidiary, and such designation will only be permitted if (1) such Indebtedness is permitted under Section 4.09(a) hereof, calculated on a pro forma basis as if such designation had occurred at the beginning of the four-quarter reference period; and (2) no Default or Event of Default would be in existence following such designation.

Section 4.19 Changes in Covenants When Notes Rated Investment Grade

If on any date following the date of this Supplemental Indenture:

(1) the rating assigned to the Notes by each of S&P and Moody’s is an Investment Grade Rating; and

(2) no Default or Event of Default shall have occurred and be continuing, then, beginning on that day and subject to the provisions of the following two paragraphs, the covenants specifically listed under the following Sections of this Supplemental Indenture will be suspended as to the Notes:

(a) Section 4.10 hereof;

(b) Section 4.07 hereof;

(d) Section 4.08 hereof;

(e) Section 4.18 hereof;

(f) Section 4.11 hereof; and

(g) clause (4) of Section 5.01 hereof.

Clauses (a) through (g) above are collectively referred to as the “Suspended Covenants.”

During any period that the foregoing covenants have been suspended, the Company’s Board of Directors may not designate any of its Subsidiaries as Unrestricted Subsidiaries or Excluded Project Subsidiaries pursuant to Section 4.18 hereof, the second paragraph of the definition of Unrestricted Subsidiary, or the definition of Excluded Project Subsidiary, unless it could do so if the foregoing covenants were in effect.

If at any time the Notes are downgraded from an Investment Grade Rating by either S&P or Moody’s, the Suspended Covenants will thereafter be reinstated as if such covenants had never been suspended and be applicable pursuant to the terms of this Supplemental Indenture (including in connection with performing any calculation or assessment to determine compliance with the terms of the indenture), unless and until the Notes subsequently attain an Investment Grade Rating from each of S&P and Moody’s (in which event the Suspended Covenants will again be suspended for such time that the Notes maintain an Investment Grade Rating from each of S&P and Moody’s); provided, however, that no Default, Event of Default or breach of any kind will be deemed to exist under this Supplemental Indenture, the Notes or the Subsidiary Guarantees with respect to the Suspended Covenants based on, and none of the Company or any of its Subsidiaries will bear any liability for, any actions taken or events occurring after the Notes attain an Investment Grade Rating from each of S&P and Moody’s and before any reinstatement of the Suspended Covenants as provided above, or any actions taken at any time pursuant to any contractual obligation arising prior to the reinstatement, regardless of whether those actions or events would have been permitted if the applicable Suspended Covenant had remained in effect during such period.

(2) the Person formed by or surviving any such consolidation or merger (if other than the Company) or the Person to which such sale, assignment, transfer, conveyance or other disposition has been made assumes all the obligations of the Company under the Notes and the Indenture pursuant to supplemental indentures or other documents and agreements reasonably satisfactory to the Trustee;

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

(4) (i) the Company or the Person formed by or surviving any such consolidation or merger (if other than the Company), or to which such sale, assignment, transfer, conveyance or other disposition has been made will, on the date of such transaction after giving pro forma effect thereto and to any related financing transactions as if the same had occurred at the beginning of the applicable four-quarter period, be permitted to incur at least $1.00 of additional Indebtedness pursuant to the Fixed Charge Coverage Ratio test set forth in the provisions of Section 4.09(a) hereof; or (ii) the Company’s Fixed Charge Coverage Ratio is greater after giving pro forma effect to such consolidation or merger and any related financing transactions as if the same had occurred at the beginning of the applicable four-quarter period than the Company’s actual Fixed Charge Coverage Ratio for the period.

This Section 5.01 shall not apply to:

Holders of not less than a majority in aggregate principal amount of the then outstanding Notes by notice to the Trustee may on behalf of the Holders of all of the Notes waive any existing Default or Event of Default and its consequences hereunder, except a continuing Default or Event of Default in the payment of the principal of, premium, if any, or interest on, the Notes (including in connection with an offer to purchase); provided, however, that the Holders of a majority in aggregate principal amount of the then outstanding Notes may rescind an acceleration and its consequences, including any related payment default that resulted from such acceleration. 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 the Indenture; but no such waiver shall extend to any subsequent or other Default or impair any right consequent thereon.

Subject to certain limitations, Holders of a majority in principal amount of the Notes that are then outstanding may direct the Trustee in its exercise of any trust or power.

Subject to the provisions of this Supplemental Indenture relating to the duties of the Trustee, in case an Event of Default occurs and is continuing, the Trustee will be under no obligation to exercise any of the rights or powers under this Supplemental Indenture at the request or direction of any holders of Notes unless such holders have offered to the Trustee reasonable indemnity or security against any loss, liability or expense.

The Trustee’s compensation will not be limited by any law on compensation of a trustee of an express trust. The Company and Guarantors, jointly and severally, shall reimburse the Trustee promptly upon request for all reasonable disbursements, advances and expenses incurred or made by it in addition to the compensation for its services.

The Trustee shall notify the Company promptly of any claim for which it may seek indemnity. Failure by the Trustee to so notify the Company shall not relieve the Company or any of the Guarantors of their obligations hereunder. The Company or such Guarantor shall defend the claim and the Trustee shall cooperate in the defense. The Trustee may have separate counsel and the Company and / or Guarantors shall pay the reasonable fees and expenses of such counsel. Neither the Company nor any Guarantor need pay for any settlement made without its consent, which consent shall not be unreasonably withheld.

(c) The obligations of the Company and the Guarantors under this Section 7.01 will survive the satisfaction and discharge of this Supplemental Indenture.

(d) When the Trustee incurs expenses or renders services after an Event of Default specified in Section 6.01(9) and (10) hereof occurs, the expenses and the compensation for the services (including the fees and expenses of its agents and counsel) are intended to constitute expenses of administration under any Bankruptcy Law.

Upon the Company’s exercise under Section 8.01 hereof of the option applicable to this Section 8.03, the Company and the Guarantors shall, subject to the satisfaction of the conditions set forth in Section 8.04 hereof, be released from each of their obligations under Sections 4.07, 4.08, 4.09, 4.10, 4.11, 4.12, 4.14, 4.15, 4.16, 4.17, 4.18, 4.19 and 4.20 hereof and clause (4) of Section 5.01 hereof with respect to the outstanding Notes on and after the date the conditions set forth in Section 8.04 hereof are satisfied (hereinafter, “Covenant Defeasance”), and the Notes will thereafter be deemed not “outstanding” for the purposes of any direction, waiver, consent or declaration or act of Holders (and the consequences of any thereof) in connection with such covenants, but will continue to be deemed “outstanding” for all other purposes hereunder (it being understood that such Notes will not be deemed outstanding for accounting purposes). For this purpose, Covenant Defeasance means that, with respect to the outstanding Notes and Subsidiary Guarantees, the Company and the Guarantors 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 will not constitute a Default or an Event of Default under Section 6.01 hereof, but, except as specified above, the remainder of the Indenture and such Notes and Subsidiary Guarantees shall be unaffected thereby. In addition, upon the Company’s exercise under Section 8.01 hereof of the option applicable to this Section 8.03, subject to the satisfaction of the conditions set forth in Section 8.04 hereof, Sections 6.01(3) and 6.01(4) hereof shall not constitute Events of Default.

Section 8.04 Conditions to Legal or Covenant Defeasance.

(a) In order to exercise either Legal Defeasance or Covenant Defeasance under either Section 8.02 or 8.03 hereof:

(1) the Company must irrevocably deposit with the Trustee, in trust, for the benefit of the Holders of the Notes, cash in U.S. dollars, non-callable Government Securities, or a combination of cash in U.S. dollars and non-callable Government Securities, in amounts as will be sufficient, in the opinion of a nationally recognized investment bank, appraisal firm or firm of

independent public accountants to pay the principal of, or interest and premium on the Notes that are then outstanding on the Stated Maturity or on the applicable redemption date, as the case may be, and the Company must specify whether the Notes are being defeased to maturity or to a particular redemption date;

(2) in the case of Legal Defeasance, the Company has delivered to the Trustee an Opinion of Counsel reasonably acceptable to the Trustee confirming that (a) the Company has received from, or there has been published by, the Internal Revenue Service a ruling or (b) since the date of this Supplemental Indenture, there has been a change in the applicable federal income tax law, in either case to the effect that, and based thereon such Opinion of Counsel will confirm that, the holders of the Notes that are then outstanding 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;

(3) in the case of Covenant Defeasance, the Company has delivered to the Trustee an Opinion of Counsel reasonably acceptable to the Trustee confirming that the holders of the Notes that are then outstanding 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;

(4) no Default or Event of Default has occurred and is continuing on the date of such deposit (other than a Default or Event of Default resulting from the borrowing of funds to be applied to such deposit);

(5) such Legal Defeasance or Covenant Defeasance will not result in a breach or violation of, or constitute a default under any material agreement or instrument (other than this Supplemental Indenture) to which the Company or any of its Subsidiaries is a party or by which the Company or any of its Subsidiaries is bound;

(6) the Company must deliver to the Trustee an Officers’ Certificate stating that the deposit was not made by the Company with the intent of preferring the Holders of Notes over the other creditors of the Company with the intent of defeating, hindering, delaying or defrauding creditors of the Company or others; and

(7) the Company must deliver to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that all conditions precedent relating to the Legal Defeasance or the Covenant Defeasance have been complied with.

Section 8.05 Deposited Money and Government Securities to be Held in Trust; Other Miscellaneous Provisions.

Subject to Section 8.06 hereof, all money and non-callable Government Securities (including the proceeds thereof) deposited with the Trustee (or other qualifying trustee, collectively for purposes of this Section 8.05, the “Trustee”) pursuant to Section 8.04 hereof in respect of the outstanding Notes shall be held in trust and applied by the Trustee, in accordance with the provisions of such Notes and the Indenture, to the payment, either directly or through any Paying Agent (including the Company acting as Paying Agent) as the Trustee may determine, to the Holders of such Notes of all sums due and to become due thereon in respect of principal, premium, if any, and interest, but such money need not be segregated from other funds except to the extent required by law.

The Company shall pay and indemnify the Trustee against any tax, fee or other charge imposed on or assessed against the cash or non-callable Government Securities deposited pursuant to Section 8.04 hereof or the principal and interest received in respect thereof other than any such tax, fee or other charge which by law is for the account of the Holders of the outstanding Notes.

Notwithstanding anything in this Article 8 to the contrary, the Trustee shall deliver or pay to the Company from time to time upon the request of the Company any money or non-callable Government Securities held by it as provided in Section 8.04 hereof which, in the opinion of a nationally recognized firm of independent public accountants expressed in a written certification thereof delivered to the Trustee (which may be the opinion delivered under Section 8.04(1) hereof), 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 8.06 Repayment to Company.

Any money deposited with the Trustee or any Paying Agent, or then held by the Company, in trust for the payment of the principal of, premium, if any, or interest on any Note and remaining unclaimed for two years after such principal, premium, if any, or interest has become due and payable shall be paid to the Company on its written request or (if then held by the Company) will be discharged from such trust; and the Holder of such Note will thereafter be permitted to 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, will thereupon cease; provided, however, that the Trustee or such Paying Agent, before being required to make any such repayment, may at the expense of the Company cause to be published once, in the New York Times and The Wall Street Journal (national edition), notice that such money remains unclaimed and that, after a date specified therein, which will not be less than 30 days from the date of such notification or publication, any unclaimed balance of such money then remaining shall be repaid to the Company.

Section 8.07 Reinstatement.

If the Trustee or Paying Agent is unable to apply any United States dollars or non-callable Government Securities in accordance with Section 8.02 or 8.03 hereof, as the case may be, by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, then the Company’s and the Guarantors’ obligations under the Indenture and the Notes and the Subsidiary Guarantees will be revived and reinstated as though no deposit had occurred pursuant to Section 8.02 or 8.03 hereof until such time as the Trustee or Paying Agent is permitted to apply all such money in accordance with Section 8.02 or 8.03 hereof, as the case may be; provided, however, that, if the Company makes any payment of principal of, premium, if any, or interest on any Note following the reinstatement of its obligations, the Company shall be subrogated to the rights of the Holders of such Notes to receive such payment from the money held by the Trustee or Paying Agent.

ARTICLE 9.
AMENDMENT, SUPPLEMENT AND WAIVER

Section 9.01 Without Consent of Holders of Notes.

Notwithstanding Article IX of the Base Indenture and Section 9.02 of this Supplemental Indenture, the Company, the Guarantors and the Trustee may amend or supplement this Supplemental Indenture, the Subsidiary Guarantees or the Notes without the consent of any Holder of Notes:

(1) to cure any ambiguity, defect or inconsistency;

(2) to provide for uncertificated notes in addition to or in place of certificated notes;

(3) to provide for the assumption of the Company’s obligations to Holders of Notes in the case of a merger or consolidation or sale of all or substantially all of the Company’s assets;

(4) to make any change that would provide any additional rights or benefits to the Holders of Notes or that does not adversely affect the legal rights under this Supplemental Indenture of any such Holder;

(5) to comply with requirements of the SEC in order to effect or maintain the qualification of this Supplemental Indenture under the Trust Indenture Act;

(6) to conform the text of this Supplemental Indenture or the Notes to any provision of the “Description of the Notes” section of the Company’s Prospectus Supplement, relating to the initial offering of the Notes, to the extent that such provision in the “Description of the Notes” was intended to be a verbatim recitation of a provision of this Supplemental Indenture or the Notes;

(7) to evidence and provide for the acceptance and appointment under this Supplemental Indenture of a successor Trustee pursuant to the requirements thereof;

(8) to provide for the issuance of Additional Notes in accordance with the limitations set forth in this Supplemental Indenture as of the date hereof; or

(9) to allow any Guarantor to execute a supplemental indenture and/or a Subsidiary Guarantee with respect to the Notes.

Upon the request of the Company accompanied by a resolution of its Board of Directors authorizing the execution of any such amended or supplemental indenture, and upon receipt by the Trustee of the documents described in Section 7.2 of the Base Indenture the Trustee shall join with the Company and the Guarantors in the execution of any amended or supplemental indenture authorized or permitted by the terms of this Supplemental Indenture and to make any further appropriate agreements and stipulations that may be therein contained, but the Trustee shall not be obligated to enter into such amended or supplemental indenture that affects its own rights, duties or immunities under the Indenture or otherwise.

Section 9.02 With Consent of Holders of Notes.

(a) Except as provided below in this Section 9.02, the Company and the Trustee may amend or supplement this Ninth Supplemental Indenture (including, without limitation, Sections 3.09, 4.10 and 4.14 hereof), the Subsidiary Guarantees and the Notes with the consent of the Holders of at least a majority in principal aggregate amount of the Notes then outstanding (including, without limitation, consents obtained in connection with a tender offer or exchange offer for, or purchase of, the Notes), and, subject to Section 6.04 hereof, any existing Default or Event of Default (other than a Default or Event of Default in the payment of the principal of, premium or interest on the Notes, except a payment default resulting from an acceleration that has been rescinded) or compliance with any provision of this Supplemental Indenture, the Subsidiary Guarantees or the Notes may be waived with the consent of the Holders of a majority in principal aggregate amount of the then outstanding Notes (including, without limitation, consents obtained in connection with a tender offer or exchange offer for, or purchase of, the Notes).

Section 1.1 of the Base Indenture shall determine which Notes are considered to be “outstanding” for purposes of this Section 9.02.

Upon the request of the Company accompanied by a resolution of its Board of Directors and upon the filing with the Trustee of evidence satisfactory to the Trustee of the consent of the Holders of Notes as aforesaid, and upon receipt by the Trustee of the documents described in Section 7.2 of the Base Indenture and Section 9.06 hereof, the Trustee shall join with the Company in the execution of such amended or supplemental indenture unless such amended or supplemental indenture directly affects the Trustee’s own rights, duties or immunities under the Indenture or otherwise, in which case the Trustee may in its discretion, but will not be obligated to, enter into such amended or supplemental indenture.

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

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

Subject to Section 6.04 hereof and Section 8.2 of the Base Indenture, the Holders of a majority in aggregate principal amount of the Notes then outstanding voting as a single class may waive compliance in a particular instance by the Company with any provision of this Supplemental Indenture or the Notes or the Subsidiary Guarantees. However, without the consent of each Holder affected, an amendment, supplement or waiver under this Section 9.02 may not (with respect to any Notes held by a non-consenting Holder):

(1) reduce the principal amount of Notes whose holders must consent to an amendment, supplement or waiver;

(2) reduce the principal of or change the fixed maturity of any Note or alter the provisions with respect to the redemption of the Notes (other than provisions relating to the covenants described in Section 3.07 hereof);

(3) reduce the rate of or change the time for payment of interest on any Note;

(4) waive a Default or Event of Default in the payment of principal of, or interest or premium on the Notes (except a rescission of acceleration of the Notes by the holders of at least a majority in aggregate principal amount of the Notes and a waiver of the payment default that resulted from such acceleration);

(5) make any Note payable in currency other than that stated in the Notes;

(6) make any change in the provisions of this Supplemental Indenture relating to waivers of past Defaults or the rights of holders of Notes to receive payments of principal of, or interest or premium on the Notes;

(7) waive a redemption payment with respect to any Note (other than a payment required by one of the covenants described in Section 3.07 hereof; or

(8) make any change in Section 9.02 hereof or Section 9.2 of the Base Indenture, as to the Notes, or in the foregoing amendment and waiver provisions.

(b) Other than as expressly provided in Section 9.02 above, the Base Indenture may only be amended, supplemented or otherwise modified as and to the extent provided in the Base Indenture.

Section 9.03 Compliance with Trust Indenture Act.

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

Section 9.04 Revocation and Effect of Consents.

Until an amendment, supplement or waiver becomes effective, a consent to it by a Holder of a Note is a continuing consent by the Holder of a Note and every subsequent Holder of a Note or portion of a Note that evidences the same debt as the consenting Holder’s Note, even if notation of the consent is not made on any Note. However, any such Holder of a Note or subsequent Holder of a Note may revoke the consent as to its Note if the Trustee receives written notice of revocation before the date the amendment, supplement or waiver becomes effective. An amendment, supplement or waiver becomes effective in accordance with its terms and thereafter binds every Holder.

Section 9.05 Notation on or Exchange of Notes.

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

Failure to make the appropriate notation or issue a new Note will not affect the validity and effect of such amendment, supplement or waiver.

Section 9.06 Trustee to Sign Amendments, etc.

The Trustee shall sign any amended or supplemental indenture authorized pursuant to this Article 9 if the amendment or supplement does not adversely affect the rights, duties, liabilities or immunities of the Trustee. The Company may not sign an amended or supplemental indenture until the Board of Directors of the Company approves it. In executing any amended or supplemental indenture, the Trustee will be entitled to receive and (subject to Section 7.1 of the Base Indenture) will be fully protected in relying upon an Officer’s Certificate and an Opinion of Counsel stating that the execution of such amended or supplemental indenture is authorized or permitted by the Indenture.

ARTICLE 10.
SUBSIDIARY GUARANTEES

Section 10.01 Guarantee.

(a) Subject to this Article 10, each of the Guarantors hereby, jointly and severally, unconditionally guarantees to each Holder of a Note authenticated and delivered by the Trustee and to the Trustee and its successors and assigns, irrespective of the validity and enforceability of the Indenture, the Notes or the obligations of the Company hereunder or thereunder, that:

(1) the principal of, premium, if any, and interest on the Notes shall be promptly paid in full when due, whether at maturity, by acceleration, redemption or otherwise, and interest on the overdue principal of and interest on the Notes, if any, if lawful, and all other obligations of the Company to the Holders or the Trustee hereunder or thereunder shall be promptly paid in full or performed, all in accordance with the terms hereof and thereof; and

(2) in case of any extension of time of payment or renewal of any Notes or any of such other obligations, that same shall be promptly paid in full when due or performed in accordance with the terms of the extension or renewal, whether at stated maturity, by acceleration or otherwise.

Failing payment when due of any amount so guaranteed or any performance so guaranteed for whatever reason, the Guarantors will be jointly and severally obligated to pay the same immediately. Each Guarantor agrees that this is a guarantee of payment and not a guarantee of collection.

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

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

(d) Each Guarantor agrees that it will not be entitled to any right of subrogation in relation to the Holders in respect of any obligations guaranteed hereby until payment in full of all obligations guaranteed hereby. Each Guarantor further agrees that, as between the Guarantors, on the one hand, and the Holders and the Trustee, on the other hand, (1) the maturity of the obligations guaranteed hereby may be accelerated as provided in Article 6 hereof for the purposes of this Subsidiary Guarantee, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the obligations guaranteed hereby, and (2) in the event of any declaration of acceleration of such obligations as provided in Article 6 hereof, such obligations (whether or not due and payable) will forthwith become due and payable by the Guarantors for the purpose of this Subsidiary Guarantee. The Guarantors will have the right to seek contribution from any non-paying Guarantor so long as the exercise of such right does not impair the rights of the Holders under the Subsidiary Guarantee.

Section 10.02 Limitation on Guarantor Liability.

Each Guarantor, and by its acceptance of Notes, each Holder, hereby confirms that it is the intention of all such parties that the Subsidiary Guarantee of such Guarantor not constitute a fraudulent transfer or conveyance for purposes of Bankruptcy Law, the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act or any similar federal or state law to the extent applicable to any Subsidiary Guarantee. To effectuate the foregoing intention, the Trustee, the Holders and the Guarantors hereby irrevocably agree that the obligations of such Guarantor will be limited to the maximum amount

that will, after giving effect to such maximum amount and all other contingent and fixed liabilities of such Guarantor that are relevant under such laws, and after giving effect to any collections from, rights to receive contribution from or payments made by or on behalf of any other Guarantor in respect of the obligations of such other Guarantor under this Article 10, result in the obligations of such Guarantor under its Subsidiary Guarantee not constituting a fraudulent transfer or conveyance.

Section 10.03 Execution and Delivery of Subsidiary Guarantee.

To evidence its Subsidiary Guarantee set forth in Section 10.01, each Guarantor hereby agrees that a notation of such Subsidiary Guarantee substantially in the form attached as Exhibit B hereto shall be endorsed by an Officer of such Guarantor on each Note authenticated and delivered by the Trustee and that this Supplemental Indenture shall be executed on behalf of such Guarantor by one of its Officers.

Each Guarantor hereby agrees that its Subsidiary Guarantee set forth in Section 10.01 will remain in full force and effect notwithstanding any failure to endorse on each Note a notation of such Subsidiary Guarantee.

If an Officer whose signature is on this Supplemental Indenture or on the Subsidiary Guarantee no longer holds that office at the time the Trustee authenticates the Note on which a Subsidiary Guarantee is endorsed, the Subsidiary Guarantee will be valid nevertheless.

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

In the event that the Company creates or acquires any Domestic Subsidiary after the Issue Date, if required by Section 4.17 hereof, the Company shall cause such Domestic Subsidiary to comply with the provisions of Section 4.17 hereof and this Article 10, to the extent applicable.

Section 10.04 Guarantors May Consolidate, etc., on Certain Terms.

Except as otherwise provided in Section 10.05 hereof, no Guarantor may sell or otherwise dispose of all or substantially all of its assets to, or consolidate with or merge with or into (whether or not such Guarantor is the surviving Person) another Person, other than the Company or another Guarantor, unless:

(1) immediately after giving effect to that transaction, no Default or Event of Default exists; and

(2) either:

(a) subject to Section 10.05 hereof, the Person acquiring the property in any such sale or disposition or the Person formed by or surviving any such consolidation or merger assumes all the obligations of that Guarantor under this Supplemental Indenture and its Subsidiary Guarantee pursuant to supplemental agreements reasonably satisfactory to the Trustee;

(b) the Net Proceeds of such sale or other disposition are applied in accordance with the applicable provisions of this Supplemental Indenture, including without limitation, Section 4.10 hereof; or

In case of any such consolidation, merger, sale or conveyance and upon the assumption by the successor Person, by supplemental indenture, executed and delivered to the Trustee and satisfactory in form to the Trustee, of the Subsidiary Guarantee endorsed upon the Notes and the due and punctual performance of all of the covenants and conditions of this Supplemental Indenture to be performed by the Guarantor, such successor Person shall succeed to and be substituted for the Guarantor with the same effect as if it had been named herein as a Guarantor. Such successor Person thereupon may cause to be signed any or all of the Subsidiary Guarantees to be endorsed upon all of the Notes issuable hereunder which theretofore shall not have been signed by the Company and delivered to the Trustee. All the Subsidiary Guarantees so issued will in all respects have the same legal rank and benefit under this Supplemental Indenture as the Subsidiary Guarantees theretofore and thereafter issued in accordance with the terms of this Supplemental Indenture as though all of such Subsidiary Guarantees had been issued on the Issue Date.

Except as set forth in Articles 4 and 5 hereof, and notwithstanding clauses (a) and (b) above, nothing contained in this Supplemental Indenture or in any of the Notes will prevent any consolidation or merger of a Guarantor with or into the Company or another Guarantor, or will prevent any sale or conveyance of the property of a Guarantor as an entirety or substantially as an entirety to the Company or another Guarantor.

Section 10.05 Releases.

(a) The Subsidiary Guarantee of a Guarantor shall be released automatically:

(1) in connection with any sale or other disposition of all or substantially all of the assets of that Guarantor (including by way of merger or consolidation) to a Person that is not (either before or after giving effect to such transaction) the Company or a Restricted Subsidiary of the Company, if the sale or other disposition does not violate the provisions of Section 4.10 hereof;

(2) in connection with any sale or other disposition of Capital Stock of that Guarantor to a Person that is not (either before or after giving effect to such transaction) the Company or a Restricted Subsidiary of the Company, if (a) the sale or other disposition does not violate the provisions of Section 4.10 hereof and (b) following such sale or other disposition, that Guarantor is not a direct or indirect Subsidiary of the Company;

(3) if the Company designates any Restricted Subsidiary that is a Guarantor to be an Unrestricted Subsidiary in accordance with the applicable provisions of this Supplemental Indenture;

(4) the date that any Subsidiary that is not an Excluded Subsidiary becomes an Excluded Subsidiary;

(5) upon defeasance or satisfaction and discharge of the Notes as provided in Sections 8.01, 8.02, 8.03, 8.04 and 11.01 hereof;

(6) upon the dissolution of a Guarantor that is permitted under this Supplemental Indenture; or

(7) otherwise with respect to the Guarantee of any Guarantor, upon:

(A) the prior consent of Holders of at least a majority in aggregate principal amount of the Notes then outstanding;

(B) the consent of requisite lenders under the Credit Agreement (as amended, restated, modified, renewed, refunded, replaced or refinanced from time to time) to the release of such Guarantor’s Guarantee of all Obligations under the Credit Agreement; or

(C) the contemporaneous release of such Guarantor’s Guarantee of all Obligations under the Credit Agreement (as amended, restated, modified, renewed, refunded, replaced or refinanced from time to time).

(b) The Subsidiary Guarantee of a Guarantor shall be released with respect to the Notes automatically upon Legal Defeasance, Covenant Defeasance or satisfaction and discharge of this Supplemental Indenture pursuant to Articles 8 and 11 hereof.

(c) Upon delivery by the Company to the Trustee of an Officer’s Certificate and an Opinion of Counsel to the effect that the action or event giving rise to the applicable release has occurred or was made by the Company in accordance with the provisions of this Supplemental Indenture, including without limitation Section 4.10 hereof, the Trustee shall execute any documents reasonably required in order to evidence the release of any Guarantor from its obligations under its Subsidiary Guarantee.

(d) Any Guarantor not released from its obligations under its Subsidiary Guarantee as provided in this Section 10.05 will remain liable for the full amount of principal of and interest and premium, if any, on the Notes and for the other obligations of any Guarantor under the Indenture as provided in this Article 10.

ARTICLE 11.
SATISFACTION AND DISCHARGE

Section 11.01 Satisfaction and Discharge.

This Supplemental Indenture will be discharged and will cease to be of further effect as to all Notes issued hereunder, when:

(1) either:

(a) all Notes that have been authenticated, except lost, stolen or destroyed Notes that have been replaced or paid and Notes for whose payment money has been deposited in trust and thereafter repaid to the Company, have been delivered to the Trustee for cancellation; or

(b) all Notes that have not been delivered to the Trustee for cancellation have become due and payable by reason of the mailing of a notice of redemption or otherwise or will become due and payable within one year and the Company or any Guarantor has irrevocably deposited or caused to be deposited with the Trustee as trust funds in trust solely for the benefit of the Holders, cash in U.S. dollars, non-callable Government Securities, or a combination of cash in U.S. dollars and non-callable Government Securities, in such amounts as will be sufficient without consideration of any reinvestment of interest, to pay and discharge the entire indebtedness on the Notes not delivered to the Trustee for cancellation for principal, premium, if any, and accrued interest to the date of maturity or redemption;

(2) no Default or Event of Default has occurred and is continuing on the date of the deposit (other than a Default or Event of Default resulting from the borrowing of funds to be applied to such deposit) and the deposit will not result in a breach or violation of, or constitute a

default under, any other instrument to which the Company or any Guarantor is a party or by which the Company or any Guarantor is bound;

(3) the Company or any Guarantor has paid or caused to be paid all sums payable by it under this Supplemental Indenture; and

(4) the Company has delivered irrevocable instructions to the Trustee under this Supplemental Indenture to apply the deposited money toward the payment of the Notes at maturity or the redemption date, as the case may be.

In addition, the Company must deliver an Officer’s Certificate and an Opinion of Counsel to the Trustee stating that all conditions precedent to satisfaction and discharge have been satisfied.

Notwithstanding the satisfaction and discharge of this Supplemental Indenture, if money has been deposited with the Trustee pursuant to subclause (b) of clause (1) of this Section, the provisions of Section 11.02 hereof and Section 8.06 hereof will survive. In addition, nothing in this Section 11.01 will be deemed to discharge those provisions of Section 7.01 hereof and Section 7.7 of the Base Indenture, that, by their terms, survive the satisfaction and discharge of this Supplemental Indenture.

Section 11.02 Application of Trust Money.

Subject to the provisions of Section 8.06 hereof, all money deposited with the Trustee pursuant to Section 11.01 hereof shall be held in trust and applied by it, in accordance with the provisions of the Notes and the 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, 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.

If the Trustee or Paying Agent is unable to apply any money or Government Securities in accordance with Section 11.01 hereof by reason of any legal proceeding or by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, the Company’s and any Guarantor’s obligations under this Supplemental Indenture and the Notes shall be revived and reinstated as though no deposit had occurred pursuant to Section 11.01 hereof; provided that if the Company has made any payment of principal of, premium, if any, or interest on any Notes because of the reinstatement of its obligations, the Company shall be subrogated to the rights of the Holders of such Notes to receive such payment from the money or Government Securities held by the Trustee or Paying Agent.

If the Company mails a notice or communication to Holders, it will mail a copy to the Trustee and each Agent at the same time.

7.375% Senior Notes due 2017

[Insert the Global Note Legend, if applicable pursuant to the provisions of the Supplemental Indenture]

Capitalized terms used herein have the meanings assigned to them in the Supplemental Indenture referred to below unless otherwise indicated.

(1) Interest. NRG Energy, Inc., a Delaware corporation (the “Company”), promises to pay interest on the principal amount of this Note at 7.375% per annum from November 21, 2006 until maturity. The Company shall pay interest semi-annually in arrears on January 15 and July 15 of each year, or if any such day is not a Business Day, on the next succeeding Business Day (each, an “Interest Payment Date”). Interest on the Notes will accrue from the most recent date to which interest has been paid or, if no interest has been paid, from the date of issuance; provided that if there is no existing Default in the payment of interest, and if this Note is authenticated between a record date referred to on the face hereof and the next succeeding Interest Payment Date, interest shall accrue from such next succeeding Interest Payment Date; provided, further, that the first Interest Payment Date shall be July 15, 2007. Interest will be computed on the basis of a 360-day year of twelve 30-day months.

(2) Method of Payment. The Company shall pay interest on the Notes to the Persons who are registered Holders of Notes at the close of business on the January 1 or July 1 next preceding the Interest Payment Date, even if such Notes are canceled after such record date and on or before such Interest Payment Date, except as provided in Section 2.13 of the Base Indenture with respect to defaulted interest. The Notes will be payable as to principal, premium, if any, and interest at the office or agency of the Company maintained for such purpose within the City and State of New York, or, at the option of the Company, payment of interest and may be made by check mailed to the Holders at their addresses set forth in the register of Holders; provided that payment by wire transfer of immediately available funds will be required with respect to principal of and interest and premium, if any, on, all Global Notes and all other Notes the Holders of which will have provided wire transfer instructions to the Company or the Paying Agent. Such payment shall be in such coin or currency of the United States of America as at the time of payment is legal tender for payment of public and private debts.

(3) Paying Agent and Registrar. Initially, Law Debenture Trust Company of New York, the Trustee under the Indenture, will act as Paying Agent and the Registrar. The Company may change any Paying Agent or the Registrar without notice to any Holder. The Company or any of its Subsidiaries may act in any such capacity.

(4) Indenture. This Note is one of a duly authenticated series of securities of the Company issued and to be issued in one or more series under an Indenture (the “Base Indenture”), dated as of February 2, 2006, between the Company and the Trustee, as amended by the Ninth Supplemental Indenture (the “Supplemental Indenture” and, together with the Base Indenture, the “Indenture”), dated as of November 21, 2006, among the Company, the Guarantors and the Trustee. The terms of the Notes include those stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act of 1939, as amended (15 U.S. Code §§ 77aaa-77bbbb). The Notes are subject to all such terms, and Holders are referred to the Indenture and such Act for a statement of such terms. To the extent any provision of this Note conflicts with the express provisions of the Base Indenture, the provisions of this Note shall govern and be controlling, and to the extent any provision of this Note conflicts with the express

Note

provisions of the Supplemental Indenture, the provisions of the Supplemental Indenture shall govern and be controlling. The Company shall be entitled to issue Additional Notes pursuant to Section 2.05 of the Supplemental Indenture.

(5) Optional Redemption.

(a) At any time prior to January 15, 2012, the Company may on any one or more occasions redeem up to 35% of the aggregate principal amount of the Notes, upon not less than 30 nor more than 60 days’ notice, at a redemption price of 107.375% of the principal amount, plus accrued and unpaid interest to the redemption date, with the proceeds of one or more Equity Offerings; provided that:

(1) at least 65% of the aggregate principal amount of the Notes issued pursuant to the Supplemental Indenture (excluding notes held by the Company and its Subsidiaries) remains outstanding immediately after the occurrence of such redemption; and

(2) the redemption occurs within 90 days of the date of the closing of such Equity Offering.


Year	Percentage
2012		103.688	%
2013		102.458	%
2014		101.229	%
2015 and thereafter		100.000	%

(6) Repurchase at Option of Holder.

(a) If there is a Change of Control, the Company shall be required to make an offer (a “Change of Control Offer”) to repurchase all or any part (equal to $5,000 or integral multiples of $5,000) of each Holder’s Notes at a purchase price equal to 101% of the aggregate principal amount of Notes repurchased plus accrued and unpaid interest to the date of purchase (the “Change of Control Payment”). Within 30 days following any Change of Control, the Company shall mail a notice to each Holder setting forth the procedures governing the Change of Control Offer as required by the Indenture.

Note

(b) If the Company or a Restricted Subsidiary consummates any Asset Sales, and the aggregate amount of Excess Proceeds exceeds $100.0 million, the Company shall commence an offer to all Holders of Notes and all holders of other Indebtedness that is pari passu with the Notes containing provisions similar to those set forth in the Supplemental Indenture with respect to offers to purchase (or repay, prepay or redeem, as applicable) an aggregate principal amount of Notes and such other pari passu Indebtedness that may be purchased out of the Excess Proceeds at an offer price in cash in an amount equal to 100% of the principal amount thereof plus accrued and unpaid interest to the date fixed for the closing of such offer (the “Asset Sale Offer”), in accordance with the procedures set forth in the Supplemental Indenture. To the extent that the aggregate amount of Notes and other pari passu Indebtedness tendered pursuant to an Asset Sale Offer is less than the Excess Proceeds, the Company may use such deficiency for any purpose not otherwise prohibited by the Indenture. If the aggregate principal amount of Notes and other pari passu Indebtedness surrendered by holders thereof exceeds the amount of Excess Proceeds, the Trustee shall select the Notes and other pari passu Indebtedness to be purchased on a pro rata basis. Upon completion of each Asset Sale Offer, the amount of Excess Proceeds will be reset at zero. Holders of Notes that are the subject of an offer to purchase will receive an Asset Sale Offer from the Company prior to any related purchase date and may elect to have such Notes purchased by completing the form entitled “Option of Holder to Elect Purchase” on the reverse of the Notes.

(7) Notice of Redemption. Notice of redemption will be mailed at least 30 days but not more than 60 days before the redemption date to each Holder whose Notes are to be redeemed at its registered address. Notes in denominations larger than $5,000 may be redeemed in part but only in whole multiples of $5,000, unless all of the Notes held by a Holder are to be redeemed. On and after the redemption date interest ceases to accrue on Notes or portions thereof called for redemption.

(8) Denominations, Transfer, Exchange. The Notes are in registered form without coupons in denominations of $5,000 and integral multiples of $5,000. The transfer of Notes may be registered and Notes may be exchanged as provided in the Supplemental Indenture. The Registrar and the Trustee may require a Holder, among other things, to furnish appropriate endorsements and transfer documents and the Company may require a Holder to pay any taxes and fees required by law or permitted by the Supplemental Indenture. The Company need not exchange or register the transfer of any Note or portion of a Note selected for redemption, except for the unredeemed portion of any Note being redeemed in part. Also, the Company need not exchange or register the transfer of any Notes for a period of 15 days before a selection of Notes to be redeemed or during the period between a record date and the corresponding Interest Payment Date.

(9) Persons Deemed Owners. The registered Holder of a Note may be treated as its owner for all purposes.

(10) Amendment, Supplement and Waiver. The Base Indenture may be amended as provided therein. Subject to certain exceptions, the Supplemental Indenture or the Notes may be amended or supplemented with the consent of the Holders of at least a majority in principal amount of the then outstanding Notes, and any existing default or compliance with any provision of the Supplemental Indenture or the Notes may be waived with the consent of the Holders of a majority in principal amount of the then outstanding Notes. Without the consent of any Holder of a Note, the Supplemental Indenture or the Notes may be amended or supplemented (i) to cure any ambiguity, defect or inconsistency, (ii) to provide for uncertificated Notes in addition to or in place of certificated Notes, (iii) to provide for the assumption of the Company’s obligations to

Note

Holders of the Notes in the case of a merger or consolidation or sale of all or substantially all of the Company’s assets pursuant to Article 5 of the Supplemental Indenture, (iv) to make any change that would provide any additional rights or benefits to the Holders of Notes, including the addition of guarantees, or that does not adversely affect the legal rights under the Supplemental Indenture of any such Holder, (v) to comply with the requirements of the SEC in order to effect or maintain the qualification of the Indenture under the Trust Indenture Act, (vi) to conform the text of the Supplemental Indenture or the Notes to any provision of the Description of Notes in the Prospectus Supplement to the extent that such provision in the Description of Notes was intended to be a verbatim recitation of a provision of the Supplemental Indenture or the Notes, (viii) to evidence and provide for the acceptance and appointment under the Indenture of a successor trustee pursuant to the requirements thereof, (ix) to provide for the Issuance of Additional Notes in accordance with the limitations set forth in the Supplemental Indenture and (x) to allow any Guarantor to execute a supplemental indenture and/or Subsidiary Guarantee with respect to the Notes to become a Guarantor.

(11) Defaults and Remedies. Events of Default include: (1) default for 30 days in the payment when due of interest on the Notes; (2) default in payment when due of the principal of, or premium, if any, on the Notes; (3) failure by the Company or any of its Restricted Subsidiaries for 30 days after written notice given by the Trustee or Holders, to comply with any of the other agreements in the Supplemental Indenture; (4) default under any mortgage, indenture or instrument under which there may be issued or by which there may be secured or evidenced any Indebtedness for money borrowed by the Company or any of its Restricted Subsidiaries (or the payment of which is guaranteed by the Company or any of its Restricted Subsidiaries) whether such Indebtedness or guarantee now exists, or is created after the date of this Supplemental Indenture, if that default: (A) is caused by a failure to pay principal of, or interest or premium, if any, on such Indebtedness prior to the expiration of the grace period provided in such Indebtedness on the date of such default (a “Payment Default”); or (B) results in the acceleration of such Indebtedness prior to its express maturity, and, in each case, the principal amount of any such Indebtedness, together with the principal amount of any other such Indebtedness under which there has been a Payment Default or the maturity of which has been so accelerated, aggregates $100.0 million or more; provided that this clause (4) shall not apply to (i) secured Indebtedness that becomes due as a result of the voluntary sale or transfer of the property or assets securing such Indebtedness to a Person that is not an Affiliate of the Company; (ii) Non-Recourse Debt of the NRG Peaker Finance Company LLC; and (iii) Non-Recourse Debt of the Company or any of its Subsidiaries (except to the extent that the Company or any of its Restricted Subsidiaries that are not parties to such Non-Recourse Debt becomes directly or indirectly liable, including pursuant to any contingent obligation, for any Indebtedness thereunder and such liability, individually or in the aggregate, exceeds $100.0 million); (5) one or more judgments for the payment of money in an aggregate amount in excess of $100.0 million (excluding therefrom any amount reasonably expected to be covered by insurance) shall be rendered against the Company any Restricted Subsidiary or any combination thereof and the same shall not have been paid, discharged or stayed for a period of 60 days after such judgment became final and non-appealable; (6) except as permitted by the Supplemental Indenture, any Subsidiary Guarantee shall be held in any final and non-appealable judicial proceeding to be unenforceable or invalid or shall cease for any reason to be in full force and effect or any Guarantor (or any group of Guarantors) that constitutes a Significant Subsidiary, or any Person acting on behalf of any Guarantor (or any group of Guarantors) that constitutes a Significant Subsidiary, shall deny or disaffirm its or their obligations under its or their Subsidiary Guarantee(s); (7) the Company or any of its Restricted Subsidiaries that is a Significant Subsidiary or any group of Restricted Subsidiaries of the Company that, taken together, would constitute a Significant Subsidiary pursuant to or within the meaning of Bankruptcy Law: (A) commences a voluntary case, (B)

Note

consents to the entry of an order for relief against it in an involuntary case, (C) consents to the appointment of a custodian of it or for all or substantially all of its property, (D) makes a general assignment for the benefit of its creditors, or (E) generally is not paying its debts as they become due; or (10) a court of competent jurisdiction enters an order or decree under any Bankruptcy Law that: (A) is for relief against the Company or any of its Restricted Subsidiaries that is a Significant Subsidiary or any group of Restricted Subsidiaries of the Company that, taken together, would constitute a Significant Subsidiary in an involuntary case; (B) appoints a custodian of the Company or any of its Restricted Subsidiaries that is a Significant Subsidiary or any group of Restricted Subsidiaries of the Company that, taken together, would constitute a Significant Subsidiary or for all or substantially all of the property of the Company or any of its Restricted Subsidiaries that is a Significant Subsidiary or any group of Restricted Subsidiaries of the Company that, taken together, would constitute a Significant Subsidiary; or (C) orders the liquidation of the Company or any of its Restricted Subsidiaries that is a Significant Subsidiary or any group of Restricted Subsidiaries of the Company that, taken together, would constitute a Significant Subsidiary; and the order or decree remains unstayed and in effect for 60 consecutive days.

(12) Trustee Dealings with Company. The Trustee, in its individual or any other capacity, may make loans to, accept deposits from, and perform services for the Company or its Affiliates, and may otherwise deal with the Company or its Affiliates, as if it were not the Trustee. However, in the event that the Trustee acquires any conflicting interest it must eliminate such conflict within 90 days, apply to the SEC for permission to continue as trustee or resign. Any Agent may do the same with like rights and duties. The Trustee is also subject to and entitled to the benefits of Article VII of the Base Indenture.

(13) No Recourse Against Others. No director, officer, employee, incorporator or stockholder of the Company or any Guarantor, as such, will have any liability for any obligations of the Company or the Guarantors under the Notes, the Indenture, the Subsidiary Guarantees or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each Holder of Notes by accepting a Note waives and releases all such liability. The waiver and release are part of the consideration for issuance of the Notes. The waiver may not be effective to waive liabilities under the federal securities laws.

(14) Authentication. This Note will not be valid until authenticated by the manual signature of the Trustee or an authenticating agent.

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

(16) CUSIP Numbers. Pursuant to a recommendation promulgated by the Committee on Uniform Security Identification Procedures, the Company has caused CUSIP numbers to be printed on the Notes and the Trustee may use CUSIP numbers in notices of redemption as a convenience to Holders. No representation is made as to the accuracy of such numbers either as printed on the Notes or as contained in any notice of redemption and reliance may be placed only on the other identification numbers placed thereon.

(17) Governing Law. THE INTERNAL LAW OF THE STATE OF NEW YORK WILL GOVERN AND BE USED TO CONSTRUE THE SUPPLEMENTAL INDENTURE, THE NOTES AND THE SUBSIDIARY GUARANTEES WITHOUT GIVING EFFECT

Note

TO APPLICABLE PRINCIPLES OF CONFLICTS OF LAW TO THE EXTENT THAT THE APPLICATION OF THE LAWS OF ANOTHER JURISDICTION WOULD BE REQUIRED THEREBY.
