(a) Transfer and Exchange of Global Notes. A Global Note may not be transferred except as a whole by the Depositary to a nominee of the Depositary, by a nominee of the Depositary to the Depositary or to another nominee of the Depositary, or by the Depositary or any such nominee to a successor Depositary or a nominee of such successor Depositary. All Global Notes will be exchanged by the Issuers for Definitive Notes if:

(1) the Issuers deliver to the Trustee notice from the Depositary that it is unwilling or unable to continue to act as Depositary or that it is no longer a clearing agency registered under the Exchange Act and, in either case, a successor Depositary is not appointed by the Issuers within 120 days after the date of such notice from the Depositary;

Except as set forth in Section 2.09 hereof, a Note does not cease to be outstanding because any of the Issuers or an Affiliate of any of the Issuers holds the Note.

If a Note is replaced pursuant to Section 2.07 hereof, it ceases to be outstanding unless the Trustee receives proof satisfactory to it that the replaced Note is held by a protected purchaser.

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

If the Paying Agent (other than any of the Issuers, a Subsidiary or an Affiliate of any thereof) holds in trust for the benefit of the Holders of the Notes, on a redemption date or maturity date, money sufficient to pay Notes payable on that date, then on and after that date such Notes will be deemed to be no longer outstanding and will cease to accrue interest.

Section 2.09 Treasury Notes.

In determining whether the Holders of the required principal amount of Notes have concurred in any direction, waiver or consent, Notes owned by the Issuers or any Guarantors, or by any Person directly or indirectly

40

controlling or controlled by or under direct or indirect common control with the Issuers or any Guarantors, will be considered as though not outstanding, except that for the purposes of determining whether the Trustee will be protected in relying on any such direction, waiver or consent, only Notes that the Trustee knows are so owned will be so disregarded.

Section 2.10 Temporary Notes.

Until certificates representing Notes are ready for delivery, the Issuers may prepare and the Trustee, upon receipt of an Authentication Order, will authenticate temporary Notes. Temporary Notes will be substantially in the form of certificated Notes but may have variations that the Issuers consider appropriate for temporary Notes and as may be reasonably acceptable to the Trustee. Without unreasonable delay, the Issuers will prepare and the Trustee will authenticate definitive Notes in exchange for temporary Notes.

Holders of temporary Notes will be entitled to all of the benefits of this Indenture.

Section 2.11 Cancellation.

The Issuers at any time may deliver Notes to the Trustee for cancellation. The Registrar and Paying Agent will forward to the Trustee any Notes surrendered to them for registration of transfer, exchange or payment. The Trustee and no one else will cancel all Notes surrendered for registration of transfer, exchange, payment, replacement or cancellation and will destroy canceled Notes (subject to the record retention requirements of the Exchange Act and the Trustee). Certification of the cancellation of all canceled Notes will be delivered to the Issuers upon the Issuers’ written request. The Issuers may not issue new Notes to replace Notes that it has paid or that have been delivered to the Trustee for cancellation.

Section 2.12 Defaulted Interest.

If the Issuers default in a payment of interest on the Notes, they will pay the defaulted interest in any lawful manner plus, to the extent lawful, interest payable on the defaulted interest, to the Persons who are Holders on a subsequent special record date, in each case at the rate provided in the Notes and in Section 4.01 hereof. The Issuers will notify the Trustee in writing in the form of an Officer’s Certificate of the Main Issuer of the amount of defaulted interest proposed to be paid on each Note and the date of the proposed payment. The Issuers will fix or cause to be fixed each such special record date and payment date; provided that no such special record date may be less than 10 days prior to the related payment date for such defaulted interest. At least 15 days before the special record date, the Issuers (or, upon the written request of the Issuers, the Trustee in the name and at the expense of the Issuers) will send or cause to be sent to Holders a notice that states the special record date, the related payment date and the amount of such interest to be paid.

ARTICLE III.

Section 3.01 Notices to Trustee.

If the Issuers elect to redeem Notes pursuant to the optional redemption provisions of Section 3.07 hereof, the Issuers must furnish to the Trustee, at least 30 days but not more than 60 days before a redemption date, an Officer’s Certificate of the Main Issuer setting forth:

41

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 will select Notes for redemption as follows:

(a) if the Notes are listed on any national securities exchange and the Issuers notify a Responsible Officer of the Trustee in writing of such listing, in compliance with the requirements of the principal national securities exchange on which the Notes are listed; or

(b) if the Notes are not listed on any national securities exchange, on a pro rata basis (or, in the case of Global Notes, the Notes represented thereby will be selected by lot in accordance with the Applicable Procedures).

No Notes of $2,000 or less can be redeemed in part.

Section 3.03 Notice of Redemption.

Notices of optional redemption will be given by first class mail (or electronically in the case of Global Notes) 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 optional redemption notices may be given more than 60 days prior to a redemption date if the notice is issued in connection with a defeasance of the Notes or satisfaction and discharge of this Indenture pursuant to Articles 8 or 11 hereof.

The notice shall identify the Notes to be redeemed (including CUSIP numbers) and shall state:

(a) the redemption date;

(b) the redemption price (if then determined and otherwise the basis for its determination);

(c) 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 shall be issued upon cancellation of the original Note;

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

(e) that Notes called for redemption (other than a Global Note) must be surrendered to the Paying Agent to collect the redemption price;

(f) that, unless the Issuers default in making such redemption payment, interest on Notes called for redemption ceases to accrue on and after the redemption date;

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

(h) any conditions to redemption; and

(i) 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.

If any of the Notes to be redeemed is in the form of a Global Note, then the Issuers shall modify such notice to the extent necessary to accord with the Applicable Procedures applicable to redemption.

At the Issuers’ request, the Trustee shall give the notice of redemption in the Issuers’ name and at its expense; provided, however, that the Issuers shall have delivered to the Trustee, five Business Days (or three Business Days in the case of Global Notes) prior to the date notice of such redemption is to be given to Holders (unless a shorter notice period shall be agreed to by the Trustee) and, as provided in Section 3.01, an Officer’s Certificate of the Main Issuer requesting that the Trustee give such notice and setting forth the information to be stated in such notice as provided in the preceding paragraph.

42

Section 3.04 Effect of Notice of Redemption.

Once notice of redemption is given in accordance with Section 3.03 hereof, Notes called for redemption without a condition become irrevocably due and payable on the redemption date at the redemption price.

Notice of any redemption of the Notes (including upon an Equity Offering) may, at the Main Issuer’s discretion, be given prior to a transaction or event and any such redemption or notice may, at the Main Issuer’s discretion, be subject to one or more conditions precedent, including, but not limited to, completion or occurrence of the related transaction or event, as the case may be.

In addition, if such redemption or purchase is subject to satisfaction of one or more conditions precedent, such notice shall describe each such condition, and if applicable, shall state that, in the Main Issuer’s discretion, the redemption date may be delayed until such time as any or all such conditions shall be satisfied, or such redemption or purchase may not occur and such notice may be rescinded in the event that any or all such conditions shall not have been satisfied by the redemption date, or by the redemption date as so delayed, or such notice may be rescinded at any time in the Main Issuer’s discretion if in the good faith judgment of the Main Issuer any or all of such conditions will not be satisfied. In addition, the Main Issuer may provide in such notice that payment of the redemption price and performance of the Main Issuer’s obligations with respect to such redemption may be performed by another Person.

No Notes of $2,000 or less can be redeemed in part. If any Note is to be redeemed in part only, the notice of redemption that relates to that Note will 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 will be issued in the name of the Holder upon cancellation of the original Note. Notes called for redemption without a condition precedent will become due on the date fixed for redemption. On and after the redemption date, interest will cease to accrue on Note or portions of them called for redemption, unless the Issuers default in making such redemption payment.

Section 3.05 Deposit of Redemption or Purchase Price.

On or prior to the redemption or purchase date, the Issuers will deposit no later than 11:00 a.m. New York City time on such date with the Trustee or with the Paying Agent money sufficient to pay the redemption or purchase price of and accrued interest, if any, on all Notes to be redeemed or purchased on that date. The Trustee or the Paying Agent will promptly return to the Issuers any money deposited with the Trustee or the Paying Agent by the Issuers in excess of the amounts necessary to pay the redemption or purchase price of and accrued interest, if any, on all Notes to be redeemed or purchased.

If the Issuers comply 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 Issuers 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 Issuers will issue and, upon receipt of an Authentication Order, the Trustee will authenticate for the Holder at the expense of the Issuers 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 30, 2023, the Issuers may redeem the Notes, in whole or in part, upon prior notice, by paying a redemption price equal to 100% of the principal amount of the Notes to be redeemed plus the Applicable Premium, and accrued and unpaid interest, if any, to, but excluding, the applicable redemption date

43

(subject to the right of Holders of record on the relevant Record Date to receive interest due on the relevant Interest Payment Date).

(b) At any time and from time to time on or after January 30, 2023, the Issuers may redeem the Notes, in whole or in part, upon prior notice, at a redemption price equal to the percentage of principal amount set forth below plus accrued and unpaid interest to, but excluding, the redemption date (subject to the right of Holders of record on the relevant Record Date to receive interest due on the relevant Interest Payment Date).

(c) Any redemption pursuant to this Section 3.07 shall be made pursuant to the provisions of Sections 3.01 through 3.06 hereof. The Issuers may also redeem all of the Notes at the time, at the redemption price and subject to the conditions set forth in Section 4.14(g) hereof.

Section 3.08 No Mandatory Redemption or Sinking Fund.

The Issuers are not required to make mandatory redemption payments with respect to the Notes. The Issuers may from time to time purchase Notes on the open market or otherwise in accordance with applicable laws. There will be no sinking fund payments for the Notes.

Section 3.09 Offer to Purchase by Application of Excess Proceeds.

In the event that, pursuant to Section 4.10 hereof, the Issuers shall be required to commence a pro rata Asset Sale Offer (as defined in Section 4.10) to all Holders of the Notes and all holders of other Priority Lien Debt containing provisions similar to those set forth in this Section 3.09 and Section 4.10 hereof with respect to offers to purchase or redeem with the Net Cash Proceeds of sales of assets to purchase such Notes and such other Priority Lien Debt, it shall follow the procedures specified below.

The Asset Sale Offer shall remain open for a period of at least 30 days following its commencement but no longer than 60 days, except to the extent that a longer period is required by applicable law (the “Offer Period”). Promptly after the termination of the Offer Period (the “Purchase Date”), the Issuers shall purchase the principal amount of Notes and such other Priority Lien Debt required to be purchased pursuant to Section 4.10 hereof (the “Offer Amount”) or, if less than the Offer Amount has been tendered, all Notes and other Priority Lien Debt tendered and not withdrawn in response to the Asset Sale Offer.

Upon the commencement of an Asset Sale Offer, the Issuers shall send, by first class mail (or in the case of Global Notes, in accordance with the Applicable Procedures), a notice to each of the Holders, with a copy to the Trustee. The notice shall contain all instructions and materials necessary to enable such Holders to tender Notes pursuant to the Asset Sale Offer. The Asset Sale Offer shall be made to all Holders. The notice, which shall govern the terms of the Asset Sale Offer, shall state:

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

(f) that Holders shall be entitled to withdraw their election if the Issuers, the Depositary or the Paying Agent, as the case may be, receives, not later than the expiration of the Offer Period, an electronic 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;

(g) that, if the aggregate principal amount of Notes and other Priority Lien Debt surrendered by the holders thereof exceeds the Offer Amount, the Issuers shall select the Notes and other Priority Lien Debt to be purchased on a pro rata basis based on the principal amount of the Notes and such other Priority Lien Debt surrendered (with such adjustments as may be deemed appropriate by the Issuers so that only Notes in minimum denominations of $2,000 or integral multiples of $1,000 in excess thereof, shall remain outstanding after such purchase); and

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

On the Purchase Date, the Issuers 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 validly tendered and not properly withdrawn pursuant to the Asset Sale Offer, or if less than the Offer Amount has been validly tendered and not properly withdrawn, all Notes so tendered and not withdrawn, shall deposit by 11:00 a.m., New York City time, with the Paying Agent or Depositary an amount equal to the purchase price in respect of all Notes or portions thereof accepted for payment, and shall deliver to the Trustee an Officer’s Certificate of the Main Issuer stating that such Notes or portions thereof were accepted for payment by the Issuers in accordance with the terms of this Section 3.09. The Issuers, the Depositary or the Paying Agent, as the case may be, shall promptly mail or electronically send to each tendering Holder an amount equal to the purchase price of the Notes tendered by such Holder and accepted by the Issuers for purchase, and the Issuers shall promptly issue a new Note, and the Trustee, upon receipt of an Authentication Order, shall authenticate and mail or electronically send (or cause to be transferred by book entry) 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 electronically sent by the Issuers to the Holder thereof. The Issuers 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 Issuers 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 Issuers of their obligation to maintain an office or agency in the United States for such purposes. The Issuers will give prompt written notice to the Trustee of any such designation or rescission and of any change in the location of any such other office or agency.

The Issuers hereby designate the Corporate Trust Office of the Trustee as one such office or agency of the Issuers in accordance with Section 2.03 hereof.

The Trustee shall not be obligated review or analyze any reports furnished or made available to it, or to monitor or confirm, on a continuing basis or otherwise, the Issuers’ compliance with the covenants or with respect to any reports or other documents filed or made available on any website under this Indenture or participate in any conference calls.

Any and all Defaults or Events of Default arising from a failure to furnish or file in a timely manner any information or report required by this Section 4.03 shall be deemed cured (and the Issuers shall be deemed to be in compliance with this Section 4.03) upon furnishing or filing such information or report as contemplated by this Section 4.03 (but without regard to the date on which such information or report is so furnished or filed); provided that such cure shall not otherwise affect the rights of the Holders of Notes described under Article VI hereof if principal and interest have been accelerated in accordance with the terms of this Indenture and such acceleration has not been rescinded or cancelled prior to such cure.

(A) in case the Debt to be refinanced is subordinated in right of payment to the Notes, the new Debt, by its terms or by the terms of any agreement or instrument pursuant to which it is outstanding, is expressly made subordinate in right of payment to the Notes at least to the extent that the Debt to be refinanced is subordinated to the Notes;

(10) [reserved];

(11) [reserved];

(12) Preferred Stock of a Subsidiary issued to the Main Issuer or another Subsidiary; provided that any subsequent transfer of any Capital Stock or any other event which results in any such Subsidiary ceasing to be a Subsidiary or any other subsequent transfer of any such Preferred Stock (except to the Main Issuer or another Subsidiary) shall be deemed, in each case, to be an issue of Preferred Stock;

52

(14) [reserved];

(15) Debt of the Main Issuer or any Subsidiary consisting of (i) the financing of insurance premiums solely with respect to the Mining Operations of Wilpinjong Opco or any of its Subsidiaries or (ii) take-or-pay obligations contained in supply or other arrangements;

(17) Debt of the Main Issuer not otherwise permitted hereunder in an aggregate principal amount at any time outstanding not to exceed the greater of (i) $5.0 million and (ii) 1.0% of Consolidated Net Tangible Assets.

None of the Issuers or their Subsidiaries will incur any Debt (including Permitted Debt) that is contractually subordinated in right of payment to any other Debt of the Main Issuer unless such Debt is also contractually subordinated in right of payment to the Notes on substantially identical terms; provided, however, that no Debt will be deemed to be contractually subordinated in right of payment to any other Debt of the Main Issuer solely by virtue of being unsecured or by virtue of being secured on junior priority basis.

(c) For purposes of determining compliance with this Section 4.09 and Section 4.12, in the event that an item of Debt meets the criteria of more than one of the categories of Permitted Debt described in clauses (1) through (17) of Section 4.09(b) hereof, the Main Issuer will be permitted to classify such item of Debt on the date of its Incurrence, or later reclassify all or a portion of such item of Debt, in any manner that complies with this Section 4.09. Notwithstanding the foregoing, (x) all Debt under the Term Loan Facility will be deemed to have been incurred in reliance on the exception provided in Section 4.09(b)(1) hereof and (y) all Junior Lien Debt will be deemed to have been incurred in reliance on the exception provided in Section 4.09(b)(9) hereof.

(d) The accrual of interest or Preferred Stock dividends, the accretion of accreted value, the accretion or amortization of original issue discount, the payment of interest on any Debt in the form of additional Debt with the same terms, the reclassification of Preferred Stock as Debt due to a change in accounting principles, and the payment of dividends on Preferred Stock or Disqualified Stock in the form of additional shares of the same class of Preferred Stock or Disqualified Stock will not be deemed to be an Incurrence of Debt or an issuance of Preferred Stock or Disqualified Stock for purposes of this Section 4.09; provided, in each such case, that the amount of any such accrual, accretion or payment is included in Fixed Charges of the Main Issuer as accrued. For purposes of determining compliance with any U.S. dollar-denominated restriction on the Incurrence of Debt, the U.S. dollar-equivalent principal amount of Debt denominated in a foreign currency shall be utilized, calculated based on the relevant currency exchange rate in effect on the date such Debt was incurred. Notwithstanding any other provision of this covenant, the maximum amount of Debt that the Main Issuer or any Subsidiary may incur pursuant to this covenant shall not be deemed to be exceeded solely as a result of fluctuations in exchange rates or currency values.

(e) The amount of any Debt outstanding as of any date will be:

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

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

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

(A) the Fair Market Value of such assets at the date of determination; and

(B) the amount of the Debt of the other Person.

53

Section 4.10 Asset Sales.

(a) The Main Issuer will not, and will not permit any Subsidiary to, make any Asset Sale unless the following conditions are met:

(1) The Asset Sale is for at least Fair Market Value (measured as of the date of the definitive agreement with respect to such Asset Sale).

(2) At least 90% of the aggregate consideration received by the Main Issuer or its Subsidiaries for such Asset Sale consists of cash or Cash Equivalents. For purposes of this clause (2):

(A) the assumption by the purchaser of Debt or other obligations or liabilities (as shown on the Main Issuer’s most recent balance sheet or in the footnotes thereto) (other than Subordinated Debt or other obligations or liabilities subordinated in right of payment to the Notes) of the Main Issuer or a Subsidiary pursuant to operation of law or a customary novation or assumption agreement; and

(B) instruments, notes, securities or other obligations received by the Main Issuer or such Subsidiary from the purchaser that are promptly, but in any event within 90 days of the closing, converted by the Main Issuer or such Subsidiary to cash or Cash Equivalents, to the extent of the cash or Cash Equivalents actually so received shall in each case be considered cash or Cash Equivalents.

(3) Within 365 days after the receipt of any Net Cash Proceeds from an Asset Sale, the Main Issuer or a Subsidiary may apply an amount equal to such Net Cash Proceeds at its option:

(A) to permanently prepay, repay, redeem, reduce or repurchase Debt as follows:

(i) to prepay, repay, redeem, reduce or purchase Priority Lien Debt on a pro rata basis; provided that all reductions of (or offers to reduce) Obligations under the Notes shall be made as provided under Section 3.07 hereof, through open-market purchases (to the extent such purchases are at or above 100% of the principal amount thereof plus accrued unpaid interest, to, but not including, the date of redemption) or by making an offer (in accordance with the procedures set forth below for an Asset Sale Offer) to all Holders to purchase their Notes at 100% of the principal amount thereof, plus the amount of accrued but unpaid interest, if any, to, but not including, the date of redemption, on the amount of Notes that would otherwise be prepaid;

(ii) [reserved];

(iii) [reserved]; or

(B) to acquire property, plant and equipment necessary for the conduct of the Mining Operations of Wilpinjong Opco and its Subsidiaries in the ordinary course of business (collectively, “Relevant Equipment”).

Notwithstanding the foregoing, to the extent that (i) a distribution of any or all of the Net Cash Proceeds of any Asset Sales by a Foreign Subsidiary to the Main Issuer is prohibited or delayed by applicable local law or (ii) a distribution of any or all of the Net Cash Proceeds of any Assets Sales by a Foreign Subsidiary to the Main Issuer could result in material adverse tax consequences, as reasonably determined by the Main Issuer, the portion of such Net Cash Proceeds so affected will not be required to be applied in compliance with this covenant; provided that within 365 days of the receipt of such Net Cash Proceeds, the Main Issuer shall use commercially reasonable efforts to permit repatriation of the proceeds that would otherwise be subject to this covenant without violating local law or incurring material adverse tax consequences, and, if such proceeds may be repatriated, within such 365 day period, such proceeds shall be required to be applied in compliance with this Section 4.10.

(4) The Net Cash Proceeds of an Asset Sale not applied pursuant to clause (3) within 365 days of the Asset Sale constitute “Excess Proceeds.” Excess Proceeds of less than $5.0 million will be

54

carried forward and accumulated. When the aggregate amount of the accumulated Excess Proceeds equals or exceeds such amount, the Main Issuer must, within 30 days, make an offer to purchase Notes (an “Asset Sale Offer”) having a principal amount equal to:

(A) accumulated Excess Proceeds; multiplied by

(B) a fraction (x) the numerator of which is equal to the outstanding aggregate principal amount of the Notes and (y) the denominator of which is equal to the outstanding aggregate principal amount of the Notes and all other Priority Lien Debt similarly required to be repaid, redeemed or tendered for in connection with the Asset Sale,

rounded down to the nearest $1,000. The purchase price for any Asset Sale Offer will be 100% of the principal amount, plus accrued interest, if any, to, but excluding, the date of purchase (subject to the right of Holders of record on the relevant Record Date to receive interest due on the relevant Interest Payment Date). If the Asset Sale Offer is for less than all of the outstanding Notes and Notes in an aggregate principal amount in excess of the purchase amount are tendered and not withdrawn pursuant to the Asset Sale Offer, the Main Issuer will purchase Notes having an aggregate principal amount equal to the purchase amount on a pro rata basis (in the case of Global Notes, subject to the applicable procedures of DTC), with adjustments so that only Notes in multiples of $1,000 principal amount (and in a minimum principal amount of $2,000) will be purchased. Upon completion of the Asset Sale Offer, any Excess Proceeds remaining after consummation of the Asset Sale Offer will be carried forward as Excess Proceeds and accumulated.

(b) The Issuers will 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 purchase of Notes pursuant to an Asset Sale Offer pursuant to this Section 4.10. To the extent that the provisions of any securities laws or regulations conflict with Section 3.09 hereof or this Section 4.10, the Issuers will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under Section 3.09 hereof or this Section 4.10 by virtue of such compliance.

Section 4.11 Transactions with Affiliates.

(a) The Main Issuer will not, and will not permit any Subsidiary to, directly or indirectly, enter into, renew or extend any transaction or arrangement including the purchase, sale, lease or exchange of property or assets, or the rendering of any service with any Affiliate of the Main Issuer or any Subsidiary (a “Related Party Transaction”) involving aggregate consideration in excess of $2.5 million, unless the Related Party Transaction is on fair and reasonable terms that are not materially less favorable (as reasonably determined by the Main Issuer) to the Issuers or any of the relevant Subsidiaries than those that could be obtained in a comparable arm’s-length transaction with a Person that is not an Affiliate of the Main Issuer.

(b) Any Related Party Transaction or series of Related Party Transactions with an aggregate value in excess of $5.0 million must first be approved by a majority of the Board of Directors of the Main Issuer who are disinterested in the subject matter of the transaction pursuant to a resolution by the Board of Directors of the Main Issuer.

(c) Any Related Party Transaction or series of Related Party Transactions with an aggregate value in excess of $10.0 million, the Main Issuer must deliver to the Trustee an opinion from an accounting, appraisal, or investment banking firm of national standing in the applicable jurisdiction (i) stating that its terms are not materially less favorable to the Main Issuer or any of the relevant Subsidiaries that would have been obtained in a comparable transaction with an unrelated Person or (ii) as to the fairness to the Main Issuer or any of the relevant Subsidiaries of such Related Party Transaction from a financial point of view.

(d) The following items shall not be subject to the provisions of Section 4.11(a), Section 4.11(b) and Section 4.11(c) hereof:

(1) any transaction between the Main Issuer and any of its Subsidiaries or between Subsidiaries of the Main Issuer;

55

(2) the payment of reasonable and customary regular fees to directors of the Main Issuer who are not employees of the Main Issuer;

(3) [reserved];

(4) (i) any payment pursuant to the terms of either Management Services Agreement, including the payment of management or similar fees and any indemnification and reimbursement payments required thereunder, provided that the aggregate amount of all such fees and payments may not exceed $15.0 million in any calendar year and (ii) the payment of any tax sharing payments, in the case of each of (i) and (ii) permitted under the covenant described above under Section 4.07(a) hereof;

(5) loans or advances to officers, directors or employees of the Main Issuer in the ordinary course of business of the Main Issuer or its Subsidiaries or Guarantees in respect thereof or otherwise made on their behalf (including payment on such Guarantees) but only to the extent permitted by applicable law, including the Sarbanes-Oxley Act of 2002;

(6) any employment, consulting, service or termination agreement, or reasonable and customary indemnification arrangements, entered into by the Main Issuer or any of its Subsidiaries with officers and employees of the Main Issuer or any of its Subsidiaries that are Affiliates of the Main Issuer and the payment of compensation to such officers and employees (including amounts paid pursuant to employee benefit plans, employee stock option or similar plans) so long as such agreement has been entered into in the ordinary course of business;

(7) transactions with customers, clients, suppliers, joint venture partners, managers, operators, or purchasers or sellers of goods or services (including pursuant to joint venture agreements) solely with respect to the Mining Operations of Wilpinjong Opco and its Subsidiaries in the ordinary course of business on terms at least as favorable as might reasonably have been obtained at such time from a Person that is not an Affiliate of the Main Issuer, as determined in good faith by the Main Issuer;

(8) transactions arising under any contract, agreement, instrument or other arrangement in effect on the Issue Date, as amended, modified or replaced from time to time so long as the amended, modified or new arrangements, taken as a whole at the time such arrangements are entered into, are not materially less favorable to the Main Issuer and its Subsidiaries than those in effect on the Issue Date;

(9) [reserved];

(10) transactions with any Affiliate in its capacity as a holder of Debt; provided that such Affiliate owns less than a majority of the interests of the relevant class and is treated the same as other holders;

(11) [reserved];

(12) any lease or sublease of equipment to any Affiliate in the ordinary course of business on terms at least as favorable as might reasonably have been obtained at such time from a Person that is not an Affiliate of the Main Issuer, as determined in good faith by the Main Issuer; and

(13) any agreements entered into in connection with the exchange offer resulting in the issuance of the Notes.

Section 4.12 Liens.

The Issuers will not, and will not permit any Subsidiary to, directly or indirectly, incur or permit to exist any Lien of any nature whatsoever on any of its properties or assets, whether owned at the Issue Date or thereafter acquired, to secure any Debt other than Permitted Liens.

56

Section 4.13 Corporate Existence.

(a) Subject to Article V hereof, the Issuers shall do or cause to be done all things necessary to preserve and keep in full force and effect their corporate existence, and the corporate, partnership or other existence of each of their Subsidiaries, in accordance with the respective organizational documents (as the same may be amended from time to time) of each of the Issuers or any such Subsidiary and the rights (charter and statutory), licenses and franchises of the Issuers and their respective Subsidiaries; provided, however, that the Issuers shall not be required to preserve any such right, license or franchise, or the corporate, partnership or other existence of any of their Subsidiaries, if senior management of the Issuers, as applicable, shall determine that the preservation thereof is no longer desirable in the conduct of the business of the Issuers and their respective Subsidiaries, taken as a whole, and that the loss thereof is not adverse in any material respect to the Holders of the Notes.

Section 4.14 Offer to Repurchase Upon Change of Control.

(a) Not later than 30 days following a Change of Control, the Issuers will make an offer to purchase (a “Change of Control Offer”) all outstanding Notes at a purchase price equal to 101% of the aggregate principal amount of the Notes repurchased plus accrued and unpaid interest, if any, to, but excluding, the date of purchase (the “Change of Control Payment”), subject to the rights of Holders of record on the relevant Record Date to receive interest due on the relevant Interest Payment Date; provided, however, that notwithstanding the occurrence of a Change of Control, the Issuers shall not be obligated to purchase the Notes pursuant to this Section 4.14 in the event that (i) during the 30-day period following such Change of Control, the Issuers have given the notice to exercise their right to redeem all the Notes under the terms described in Section 3.07 hereof and redeemed such Notes in accordance with such notice, unless and until there is a default in payment of the applicable redemption price or (ii) a third party makes the Change of Control Offer in the manner, at the time and otherwise in compliance with the requirements set forth in this Indenture applicable to a Change of Control Offer made by the Issuers and purchases all Notes properly tendered and not withdrawn under the offer.

(b) Not later than 30 days following any Change of Control, the Issuers shall send, by first class mail (or in the case of Global Notes, in accordance with the Applicable Procedures), to each Holder a written offer, which shall govern the terms of the Change of Control Offer, with a copy of such offer to the Trustee. In addition to including information concerning the business of the Issuers and their Subsidiaries that the Issuers in good faith believe will enable the Holders to make an informed decision with respect to the Change of Control Offer, the offer shall also state, among other things:

(1) that a Change of Control has occurred and a Change of Control Offer is being made as provided for herein, and that, although Holders are not required to tender their Notes, all Notes that are validly tendered shall be accepted for payment;

(2) the principal amount of Notes subject to the Change of Control Offer, the Change of Control Payment and the expiration date of the Change of Control Offer, which will be no earlier than 30 days and no later than 60 days after the date such written notice to the Holders and the Trustee is sent and a settlement date for purchase (the “Change of Control Payment Date”) not more than five Business Days after the expiration date;

(3) that any Note accepted for payment pursuant to the Change of Control Offer (and duly paid for on the Change of Control Payment Date) shall cease to accrue interest after the Change of Control Payment Date;

(4) that any Notes (or portions thereof) not validly tendered shall continue to accrue interest;

(5) that any Holder electing to have a Note purchased pursuant to any Change of Control 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 Issuers, a depositary, if appointed by the Issuers, or a Paying Agent at the address specified in the notice at least one (1) Business Day before the Change of Control Payment Date;

57

(6) that Holders shall be entitled to withdraw their election if the Issuers, the depositary or the Paying Agent, as the case may be, receives, not later than the close of business on the expiration date of the Change of Control Offer, an electronic 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; and

(7) the instructions and any other information necessary to enable Holders to tender their Notes (or portions thereof) and have such Notes (or portions thereof) purchased pursuant to the Change of Control Offer.

If the Change of Control Offer is sent prior to the occurrence of the Change of Control, it may be conditioned upon the consummation of the Change of Control.

(c) On or before the Change of Control Payment Date, the Issuers shall, to the extent lawful, accept for payment all Notes or portions thereof properly tendered and not withdrawn pursuant to the Change of Control Offer. Promptly after such acceptance, on the Change of Control Payment Date, the Issuers will:

(1) deposit by 11:00 a.m., New York City time, with the Paying Agent or Depositary an amount equal to the Change of Control Payment in respect of all Notes or portions thereof so tendered; and

(2) deliver or cause to be delivered to the Trustee for cancellation the Notes so accepted together with an Officer’s Certificate of the Main Issuer stating the aggregate principal amount of Notes or portions thereof being purchased by the Issuers.

(d) Notes repurchased by the Issuers pursuant to a Change of Control Offer will have the status of Notes issued but not outstanding or will be retired and cancelled at the option of the Issuers. Notes purchased by a third party pursuant to the preceding sections will have the status of Notes issued and outstanding.

(e) The Issuers 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 the purchase of the Notes pursuant to a Change of Control Offer under this Section 4.14. To the extent that the provisions of any securities laws or regulations conflict with the provisions of this Section 4.14, the Issuers will comply with the applicable securities laws and regulations and will not be deemed to have breached their obligations under this Section 4.14 by virtue of such compliance.

(f) On the Change of Control Payment Date, the Paying Agent shall mail or electronically send to each Holder of Notes accepted for payment the Change of Control Payment for such Notes (or, if all the Notes are then issued in the form of Global Notes, make such payment through the facilities of the Depositary), and the Issuers shall promptly issue a new Note, and the Trustee, upon receipt of an Issuers Order, shall authenticate and mail or electronically send (or cause to be transferred by book entry) to each Holder such new Note equal in principal amount to any unpurchased portion of the Notes surrendered; provided that each such new Note shall be in a minimum principal amount of $2,000 or an integral multiple of $1,000 in excess thereof. Interest on the Notes purchased will cease to accrue on and after the Change of Control Payment Date.

(g) In the event that Holders of not less than 90% of the aggregate principal amount of the outstanding Notes accept a Change of Control Offer and the Issuers (or the third party making the Change of Control Offer in lieu of the Issuers) purchase all of the Notes held by such Holders, the Issuers will have the right, upon not less than 30 nor more than 60 days’ prior written notice to the Holders and the Trustee, given not more than 30 days following the purchase pursuant to the Change of Control Offer, to redeem all of the Notes that remain outstanding following such purchase at a redemption price equal to the Change of Control Payment plus accrued and unpaid interest on the Notes redeemed from the date of purchase to, but excluding, the date of redemption (subject to the right of Holders of record on the relevant Record Date to receive interest due on the relevant Interest Payment Date).

Section 4.15 Note Guarantees.

The Notes will not be guaranteed by any of the Issuers’ Subsidiaries; provided that to the extent not resulting in a materially adverse tax consequence (as determined by Peabody in its good faith reasonable business

58

judgment), if any of PIC Acquisition, Wilpinjong Opco or any of the Main Issuer’s direct or indirect Subsidiaries at any time is not contractually prohibited from becoming a Guarantor (as determined by Peabody in its good faith reasonable business judgment), PIC Acquisition, Wilpinjong Opco or such Subsidiary shall become a guarantor (each, a “Guarantor”) and shall use commercially reasonable efforts to execute a supplemental indenture with the Trustee substantially in the form of Exhibit F hereto within 90 days.

Section 4.16 Excess Cash Flow.

(a) On a semi-annual basis, not later than 30 days after each date on which (i) the quarterly financial statements for the preceding fiscal quarter ending June 30 and (ii) the annual financial statements for the preceding fiscal year are required to be delivered pursuant to clause (1) of covenant described under Section 4.03 hereof, commencing with the period from February 1, 2021 to June 30, 2021, the Issuers will make an offer to purchase Notes, which shall include, without limitation, a detailed calculation of Excess Cash Flow for the relevant Excess Cash Flow Period (each such offer to purchase, an “Excess Cash Flow Offer”), having an aggregate principal amount equal to:

(1) an amount equal to 100% of Excess Cash Flow of the Main Issuer and its Subsidiaries for the Excess Cash Flow Period then ended; multiplied by

(2) a fraction (x) the numerator of which is equal to the outstanding aggregate principal amount of the Notes and (y) the denominator of which is equal to the outstanding aggregate principal amount of the Notes and all other Priority Lien Debt required to be repaid with such Excess Cash Flow,

rounded down to the nearest $1,000. The purchase price for any Excess Cash Flow Offer will be 100% of the principal amount, plus accrued interest, if any, to, but excluding, the date of purchase (subject to the right of Holders of record on the relevant Record Date to receive interest due on the relevant Interest Payment Date) (the “Excess Cash Flow Payment”). If the Excess Cash Flow Offer is for less than all of the outstanding Notes and Notes in an aggregate principal amount in excess of the purchase amount are tendered and not withdrawn pursuant to the Excess Cash Flow Offer, the Main Issuer will purchase Notes having an aggregate principal amount equal to the purchase amount on a pro rata basis (in the case of Global Notes, subject to the applicable procedures of DTC), with adjustments so that only Notes in multiples of $1,000 principal amount (and in a minimum principal amount of $2,000) will be purchased.

(3) the Issuers, or any Person acting on behalf of any of them, denies or disaffirms, in writing, any obligation of the Issuers set forth in or arising under any Note Document establishing Priority Liens;

(k) (i) any termination of the Surety Transaction Support Agreement by any sureties signatory thereto, provided that such termination or terminations result in the Main Issuer or any of its Subsidiaries making payments or delivering collateral to such sureties beyond the collateral that such sureties are entitled to as of the Issue Date, and such payments or additional collateral are in excess of a Fair Market Value (or face value with respect to delivered letters of credit or guarantees) of $20.0 million in the aggregate, or (ii) any modification of the Surety Transaction Support Agreement materially adverse to Peabody or any of its Subsidiaries;

(l) Peabody fails to comply with any obligation under the Transaction Support Agreement that survives or arises after the Issue Date (including any post-effective date covenant) and the default or breach continues for a period of 30 consecutive days after written notice to Peabody by the Trustee or to Peabody and the Trustee by the Holders of 25% or more in aggregate principal amount of the Notes; or

(m) the termination of the Management Services Agreements unless at the time of such termination there are arrangements in place providing for substantially the same services to be provided to the Main Issuer and its Subsidiaries on terms not materially less favorable to the Main Issuer and its Subsidiaries than the Management Services Agreements or the Management Services Agreements are amended in any manner materially adverse to the Main Issuer and its Subsidiaries.

Section 6.02 Acceleration.

If any Event of Default (other than an Event of Default specified in Section 6.01(g) or Section 6.01(h) hereof with respect to any Issuer) occurs and is continuing, the Trustee or the Holders of at least 25% in aggregate principal amount of the Notes then outstanding, by written notice to the Main Issuer (and to the Trustee if the notice is given by the Holders), may declare the principal of and accrued interest on the Notes to be immediately due and payable. Upon a declaration of acceleration, such principal and accrued interest will become immediately due and payable. If an Event of Default specified in Section 6.01(g) or Section 6.01(h) hereof occurs with respect to the Main Issuer, Co-Issuer or any other Subsidiary that is a Significant Subsidiary, the principal of and accrued interest on the Notes then outstanding will become immediately due and payable without any declaration or other act on the part of the Trustee or any Holder.

Without limiting the generality of the foregoing, it is understood and agreed that if the Notes are accelerated or otherwise become due prior to their Stated Maturity, in each case, as a result of an Event of Default (including, without limitation, an Event of Default under Section 6.01(g) or Section 6.01(h) hereof (including the acceleration of any portion of the Notes by operation of law)), the greater of (i) the Applicable Premium and (ii) the

68

amount by which the applicable redemption price set forth in the table under Section 3.07 hereof exceeds the principal amount of the Notes (the “Redemption Price Premium”), as applicable, with respect to an optional redemption of the Notes shall also be due and payable as though the Notes had been optionally redeemed on the date of such acceleration and shall constitute part of the Obligations with respect to the Notes in view of the impracticability and difficulty of ascertaining actual damages and by mutual agreement of the parties as to a reasonable calculation of each Holder’s lost profits as a result thereof. If the Redemption Price Premium becomes due and payable, it shall be deemed to be principal of the Notes, and interest shall accrue on the full principal amount of the Notes (including the Redemption Price Premium) from and after the applicable triggering event, including in connection with an Event of Default specified under Section 6.01(g) or Section 6.01(h) hereof. Any Redemption Price Premium payable above shall be presumed to be liquidated damages sustained by each holder as the result of the acceleration of the Notes and the Issuers and the Wilpinjong Credit Parties to the extent they provide guarantees for the Notes pursuant to Article X agree that it is reasonable under the circumstances currently existing. The premium shall also be payable in the event the Notes or this Indenture are satisfied, released or discharged through foreclosure, whether by judicial proceeding, deed in lieu of foreclosure, sale or collection of the Collateral or by any other means, or in connection with the restructuring, reorganization or compromise of the obligations by a plan of reorganization or otherwise. THE ISSUERS, AND TO THE EXTENT APPLICABLE, THE WILPINJONG CREDIT PARTIES IN ANY APPLICABLE SUPPLEMENTAL INDENTURE, EXPRESSLY WAIVE (TO THE FULLEST EXTENT THEY MAY LAWFULLY DO SO) THE PROVISIONS OF ANY PRESENT OR FUTURE STATUTE OR LAW THAT PROHIBITS OR MAY PROHIBIT THE COLLECTION OF THE FOREGOING PREMIUM IN CONNECTION WITH ANY SUCH ACCELERATION. The Issuers and if applicable, the Wilpinjong Credit Parties will expressly agree (to the fullest extent they may lawfully do so) that: (A) the Redemption Price Premium is reasonable and is the product of an arm’s length transaction between sophisticated business entities ably represented by counsel; (B) the Redemption Price Premium shall be payable notwithstanding the then prevailing market rates at the time acceleration occurs; (C) there has been a course of conduct between Holders and the Issuers giving specific consideration in this transaction for such agreement to pay the Redemption Price Premium; and (D) the Issuers shall be estopped from claiming differently than as agreed to in this paragraph. The Issuers and if applicable, the Wilpinjong Credit Parties, expressly acknowledge that their agreement to pay the Redemption Price Premium to Holders as herein described was a material inducement to investors to acquire the Notes.

Notwithstanding anything in the preceding paragraph to the contrary, in the event the Wilpinjong Mandatory Offer is consummated, no Redemption Price Premium shall be due and payable with respect to any Notes tendered and exchanged pursuant to the Wilpinjong Mandatory Offer.

Any notice of Default, notice of acceleration or instruction to the Trustee to provide a notice of Default, notice of acceleration or take any other action (a “Noteholder Direction”) provided by any one or more Holders (each a “Directing Holder”) must be accompanied by a written representation from each such Holder delivered to the Main Issuer and the Trustee that such Holder is not (or, in the case such holder is DTC or its nominee, that such Holder is being instructed solely by beneficial owners that are not) Net Short (a “Position Representation”), which representation, in the case of a Noteholder Direction relating to the delivery of a notice of Default (a “Default Direction”) shall be deemed a continuing representation until the resulting Event of Default is cured or otherwise ceases to exist or the Notes are accelerated. In addition, each Directing Holder is deemed, at the time of providing a Noteholder Direction, to covenant to provide the Main Issuer with such other information as the Main Issuer may reasonably request from time to time in order to verify the accuracy of such Holder’s Position Representation within five Business Days of request therefor (a “Verification Covenant”). In any case in which the holder is DTC or its nominee, any Position Representation or Verification Covenant required hereunder shall be provided by the beneficial owner of the Notes in lieu of DTC or its nominee and DTC shall be entitled to conclusively rely on such Position Representation and Verification Covenant in delivering its direction to the Trustee.

If, following the delivery of a Noteholder Direction, but prior to acceleration of the Notes, the Main Issuer determines in good faith that there is a reasonable basis to believe a Directing Holder was, at any relevant time, in breach of its Position Representation and provides to the Trustee an Officer’s Certificate of the Main Issuer stating that the Main Issuer has initiated litigation with a court of competent jurisdiction seeking a determination that such Directing Holder was, at such time, in breach of its Position Representation, and seeking to invalidate any Event of Default that resulted from the applicable Noteholder Direction, the cure period with respect to such Default shall be automatically stayed and the cure period with respect to such Event of Default shall be automatically reinstituted and

69

any remedy stayed pending a final and non-appealable determination of a court of competent jurisdiction on such matter. If, following the delivery of a Noteholder Direction, but prior to acceleration of the Notes, the Issuers provide to the Trustee an Officer’s Certificate of the Main Issuer stating that a Directing Holder failed to satisfy its Verification Covenant, the cure period with respect to such Default shall be automatically stayed and the cure period with respect to any Event of Default that resulted from the applicable Noteholder Direction shall be automatically reinstituted and any remedy stayed pending satisfaction of such Verification Covenant. Any breach of the Position Representation shall result in such Holder’s participation in such Noteholder Direction being disregarded; and, if, without the participation of such Holder, the percentage of Notes held by the remaining Holders that provided such Noteholder Direction would have been insufficient to validly provide such Noteholder Direction, such Noteholder Direction shall be void ab initio (except with respect to any indemnity offered to the Trustee), with the effect that such Event of Default shall be deemed never to have occurred, any acceleration voided and the Trustee shall be deemed not to have received such Noteholder Direction or any notice of such Default or Event of Default.

Notwithstanding anything in the preceding two paragraphs to the contrary, any Noteholder Direction delivered to the Trustee in connection with a Default under clauses (c), (d), (e), (f) or (j) during the pendency of an Event of Default under clause (g) or (h) as a result of a bankruptcy or similar proceeding shall not require compliance with the two immediately preceding paragraphs.

For the avoidance of doubt, the Trustee shall be entitled to conclusively rely on any Noteholder Direction delivered to it in accordance with this Indenture, shall have no duty to inquire as to or investigate the accuracy of any Position Representation, enforce compliance with any Verification Covenant, verify any statements in any Officer’s Certificate of the Main Issuer delivered to it, or otherwise make calculations, investigations or determinations with respect to Derivative Instruments, Net Shorts, Long Derivative Instruments, Short Derivative Instruments or otherwise. The Trustee shall have no liability to the Main Issuer, any Holder or any other Person in acting in good faith on a Noteholder Direction.

The Holders of a majority in principal amount of the outstanding Notes by written notice to the Main Issuer and to the Trustee may waive all past Defaults and rescind and annul a declaration of acceleration and its consequences if:

(a) all existing Events of Default, other than the nonpayment of the principal of, and interest on, the Notes that have become due solely by the declaration of acceleration, have been cured or waived; and

(b) the rescission would not conflict with any judgment or decree of a court of competent jurisdiction.

In the event of a declaration of acceleration of the Notes because an Event of Default described in Section 6.01(e) hereof has occurred and is continuing, the declaration of acceleration of the Notes shall be automatically annulled, without any action by the Trustee or the Holders, if the Event of Default or payment default triggering such Event of Default pursuant to Section 6.01(e) hereof shall be remedied or cured, or rescinded or waived by the holders of the Debt, or the Debt that gave rise to such Event of Default shall have been discharged in full, within 30 days after the declaration of acceleration with respect thereto and if (i) the annulment of the acceleration of the Notes would not conflict with any judgment or decree of a court of competent jurisdiction and (ii) all existing Events of Default, except nonpayment of principal, premium or interest on the Notes that became due solely because of the acceleration of the Notes , have been cured or waived.

Section 6.03 Other Remedies.

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

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

70

Section 6.04 Waiver of Past Defaults.

The Holders of 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 an existing Default or Event of Default and its consequences hereunder, except as otherwise provided in Section 6.02 hereof and Section 9.02 hereof. Upon any such waiver, such Default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured for every purpose of this Indenture; but no such waiver shall extend to any subsequent or other Default or impair any right consequent thereon.

Section 6.05 Control by Majority.

The Holders of a majority in aggregate principal amount of the then outstanding Notes may direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or exercising any trust or power conferred on the Trustee. However, the Trustee may refuse to follow any direction that conflicts with law, this Indenture or the other Note Documents, that may involve the Trustee in personal liability, or that the Trustee determines in good faith may be unduly prejudicial to the rights of Holders not joining in the giving of such direction (it being understood that the Trustee shall have no duty to determine whether any direction is prejudicial to any Holder). In addition, the Trustee may take any other action it deems proper that is not inconsistent with any such direction received from the Holders. Neither the Trustee nor the Collateral Trustee shall be obligated to take any action at the direction of Holders of Notes unless such Holders have offered, and if requested, provided to the Trustee and the Collateral Trustee indemnity or security satisfactory to the Trustee and the Collateral Trustee.

Section 6.06 Limitation on Suits.

A Holder of a Note may not institute any proceeding, judicial or otherwise, with respect to this Indenture, the Notes or the other Note Documents, or for the appointment of a receiver or trustee, or for any other remedy under this Indenture, the Notes or the other Note Documents, unless:

(a) the Holder of a Note has previously given to the Trustee written notice of a continuing Event of Default;

(b) the Holders of at least 25% in aggregate principal amount of outstanding Notes have made a written request to the Trustee to institute proceedings in respect of the Event of Default in its own name as Trustee under this Indenture;

(c) the Holders of the Notes have offered and, if requested, provided to the Trustee indemnity reasonably satisfactory to the Trustee against any costs, liabilities or expenses to be incurred in compliance with such request;

(d) the Trustee for 60 days after its receipt of such notice, request and offer of indemnity has failed to institute any such proceeding; and

(e) during such 60-day period, the Holders of a majority in aggregate principal amount of the then outstanding Notes have not given the Trustee a direction that is inconsistent with such written request.

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

Section 6.07 Rights of Holders to Receive Payment.

Notwithstanding anything in this Indenture to the contrary, the right of any Holder of a Note to receive payment of principal of, or interest on its Note on or after the Stated Maturities thereof, or to bring suit for the enforcement of any such payment on or after such dates, shall not be impaired or affected without the consent of that Holder.

71

Section 6.08 Collection Suit by Trustee.

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

Section 6.09 Trustee May File Proofs of Claim.

The Trustee is authorized to file such proofs of claim and other papers or documents as may be necessary or advisable in order to have the claims of the Trustee (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel) and the Holders of the Notes allowed in any judicial proceedings relative to the Issuers (or any other obligor upon the Notes), its creditors or its property and shall be entitled and empowered to collect, receive and distribute any money or other property payable or deliverable on any such claims and any custodian in any such judicial proceeding is hereby authorized by each Holder to make such payments to the Trustee, and in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due to it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 7.06 hereof. To the extent that the payment of any such compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 7.06 hereof out of the estate in any such proceeding, shall be denied for any reason, payment of the same shall be secured by a Lien on, and shall be paid out of, any and all distributions, dividends, money, securities and other properties that the Holders may be entitled to receive in such proceeding whether in liquidation or under any plan of reorganization or arrangement or otherwise. Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the Notes or the rights of any Holder, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding.

Section 6.10 Priorities.

Subject to the Collateral Trust Agreement, if the Trustee collects any money or property pursuant to this Article VI, it shall pay out the money or property in the following order:

First: to the Trustee and the Collateral Trustee, their respective agents and attorneys for amounts due under Section 7.06 hereof, including payment of all compensation, expenses and liabilities incurred, and all advances made, by the Trustee and the Collateral Trustee and the costs and expenses of collection;

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

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

The Trustee, upon written notice to the Issuers, may fix a record date and payment date for any payment to Holders pursuant to this Section 6.10.

Section 6.11 Undertaking for Costs.

In any suit for the enforcement of any right or remedy under this Indenture or in any suit against the Trustee for any action taken or omitted by it as a Trustee, a court in its discretion may require the filing by any party litigant in the suit of an undertaking to pay the costs of the suit, and the court in its discretion may assess reasonable costs, including reasonable attorneys’ fees and expenses, against any party litigant in the suit, having due regard to the merits and good faith of the claims or defenses made by the party litigant. This Section 6.11 does not apply to a suit by the Trustee, a suit by a Holder of a Note pursuant to Section 6.07 hereof, or a suit by Holders of more than 10% in aggregate principal amount of the then outstanding Notes.

72

ARTICLE VII.

TRUSTEE

Section 7.01 Duties of Trustee.

(a) If an Event of Default has occurred and is continuing and is actually known to a Responsible Officer of the Trustee, the Trustee will exercise such of the rights and powers vested in it by this Indenture, and use the same degree of care and skill in its exercise, as a prudent person would exercise or use under the circumstances in the conduct of such person’s own affairs.

(b) Except during the continuance of an Event of Default that is actually known to a Responsible Officer of the Trustee:

(1) the duties of the Trustee will be determined solely by the express provisions of this Indenture and the Trustee need perform only those duties that are specifically set forth in this Indenture and no others, and no implied covenants or obligations shall be read into this Indenture against the Trustee; and

(2) in the absence of bad faith on its part, the Trustee may conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon certificates or opinions furnished to the Trustee and conforming to the requirements of this Indenture. However, the Trustee will examine the certificates and opinions to determine whether or not they conform to the requirements of this Indenture (but need not confirm or investigate the accuracy of mathematical calculations stated therein).

(c) The Trustee may not be relieved from liabilities for its own grossly negligent action, its own grossly negligent failure to act, or its own willful misconduct, except that:

(1) this paragraph does not limit the effect of paragraphs (b) or (e) of this Section 7.01;

(2) the Trustee will not be liable for any error of judgment made in good faith by a Responsible Officer, unless it is proved that the Trustee was grossly negligent in ascertaining the pertinent facts; and

(3) the Trustee will not be liable with respect to any action it takes or omits to take in good faith in accordance with a direction received by it pursuant to Section 6.05 hereof.

(d) Whether or not therein expressly so provided, every provision of this Indenture that in any way relates to the Trustee is subject to paragraphs (a), (b), (c) and (e) of this Section 7.01.

(e) No provision of this Indenture will require the Trustee to expend or risk its own funds or incur any liability.

(f) The Trustee will not be liable for interest on any money received by it except as the Trustee may agree in writing with the Issuers. Money held in trust by the Trustee need not be segregated from other funds except to the extent required by law. The Trustee shall not be required to give any bond or surety in respect of the performance of its powers or duties under this Indenture.

Section 7.02 Rights of Trustee.

(a) The Trustee may conclusively rely and shall be protected in acting or refraining from acting upon any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, judgment, bond, debenture, note, other evidence of indebtedness or other paper or upon any document believed by it to be genuine and to have been signed or presented by the proper Person. The Trustee need not investigate any fact or matter stated in the document.

(b) Before the Trustee acts or refrains from acting, it may require an Officer’s Certificate of the Main Issuer or an Opinion of Counsel or both. The Trustee will not be liable for any action it takes or omits to take in

73

good faith in reliance on such Officer’s Certificate of the Main Issuer or Opinion of Counsel. The Trustee may consult with counsel and the advice of such counsel or any Opinion of Counsel will be full and complete authorization and protection from liability in respect of any action taken, suffered or omitted by it hereunder in good faith and in reliance thereon.

(c) The Trustee may act through its attorneys and agents and will not be responsible for the misconduct or negligence of any agent or attorney appointed with due care.

(d) The Trustee will not be liable for any action it takes or omits to take in good faith that it believes to be authorized or within the rights or powers conferred upon it by this Indenture.

(f) The Trustee will be under no obligation to exercise any of the rights or powers vested in it by this Indenture at the request or direction of any of the Holders unless a Responsible Officer has actual knowledge thereof and such Holders have offered, and if requested, provided, to the Trustee indemnity or security satisfactory to the Trustee against the losses, liabilities and expenses that might be incurred by it in compliance with such request or direction.

(g) The Trustee shall not be deemed to have notice or be charged with knowledge of any default or Event of Default under the Notes unless written notice of such default or Event of Default from the Issuers or any Holder of Notes is received by a Responsible Officer of the Trustee at the Corporate Trust Office of the Trustee, and such notice references the Notes and this Indenture.

(h) The rights, privileges, protections, immunities and benefits given to the Trustee, including, without limitation, its right to be indemnified, are extended to, and shall be enforceable by, the Trustee in each of its capacities hereunder, the Collateral Trustee, and each agent, custodian and other Person employed to act hereunder.

(i) Before the Trustee acts or refrains from acting, it may request that the Main Issuer deliver a certificate setting forth the names of individuals and/or titles of officers authorized at such time to take specified actions pursuant to this Indenture, which certificate may be signed by any person authorized to sign an Officer’s Certificate of the Main Issuer, including any person specified as so authorized in any such certificate previously delivered and not superseded.

(j) Anything in this Indenture notwithstanding, in no event shall the Trustee be liable for special, indirect, incidental, punitive or consequential loss or damage of any kind whatsoever (including but not limited to loss of profit), even if the Trustee has been advised as to the likelihood of such loss or damage and regardless of the form of action.

(k) The Trustee shall not be responsible or liable for any failure or delay in the performance of its obligations under this Indenture arising out of or caused, directly or indirectly, by circumstances beyond its control, including, without limitation, any provision of any law or regulation or any act of any Governmental Authority; acts of God; earthquakes; fire; flood; terrorism; wars and other military disturbances; sabotage; epidemics or pandemics; riots; interruptions; loss or malfunctions of utilities, computer (hardware or software) or communication services; the unavailability of the Federal Reserve Bank wire or telex or other wire or communication facility; accidents; labor disputes; and acts of civil or military authority.

74

Section 7.03 Individual Rights of Trustee.

The Trustee in its individual or any other capacity may become the owner or pledgee of Notes and may otherwise deal with the Issuers or any Affiliate of the Issuers with the same rights it would have if it were not Trustee. However, in the event that the Trustee acquires any conflicting interest it must eliminate such conflict within 90 days or resign. Any Agent may do the same with like rights and duties. The Trustee is also subject to Sections 7.08 and 7.09 hereof.

Section 7.04 Trustee’s Disclaimer.

The Trustee will not be responsible for and makes no representation as to the validity or adequacy of this Indenture or the Notes, it shall not be accountable for the Issuers’ use of the proceeds from the Notes or any money paid to the Issuers or upon the Issuers’ direction under any provision of this Indenture, it will not be responsible for the use or application of any money received by any Paying Agent other than the Trustee, and it will not be responsible for any statement or recital herein or any statement in the Notes or any other document in connection with the sale of the Notes or pursuant to this Indenture other than its certificate of authentication.

Section 7.05 Notice of Defaults.

If any Default occurs and is continuing and is actually known to a Responsible Officer of the Trustee, the Trustee will send notice of the Default to each Holder within 90 days after it occurs, unless the Default has been cured, provided that except in the case of a default in the payment of the principal of or interest on, any Note, the Trustee may withhold the notice if and so long as the Trustee in good faith determines that withholding the notice is in the interests of the Holders. The Trustee will not be deemed to have knowledge of any Defaults or Events of Default unless written notice of an event, which is in fact a Default, has been delivered to the Trustee at its office specified in this Indenture and such notice references the Notes and the Indenture and states it is a “Notice of Default.”

Section 7.06 Compensation and Indemnity.

(a) The Issuers will pay to the Trustee and the Collateral Trustee from time to time such compensation as is agreed in writing to from time to time by the Issuers and the Trustee or Collateral Trustee, as applicable, for its acceptance of this Indenture and services hereunder. The Trustee’s and the Collateral Trustee’s compensation will not be limited by any law on compensation of a Trustee of an express trust. The Issuers will reimburse the Trustee and the Collateral Trustee promptly upon request for all reasonable disbursements, advances and expenses incurred or made by it in addition to the compensation for its services except for any such disbursement, advance or expense as shall have been caused by the Trustee’s or Collateral Trustee’s gross negligence or willful misconduct (as determined by a final, non-appealable order of a court of competent jurisdiction). Such expenses will include the reasonable compensation, disbursements and expenses of the Trustee’s and Collateral Trustee’s respective agents and counsel.

(b) The Issuers and any Guarantors, jointly and severally, will indemnify the Trustee and the Collateral Trustee (which for purposes of this Section 7.06(b) shall include each of their officers, directors, employees and agents) against any and all losses, liabilities or expenses incurred by it arising out of or in connection with the acceptance or administration of its duties under this Indenture, including the reasonable costs and expenses of enforcing this Indenture against the Issuers (including this Section 7.06) and defending itself against any claim (whether asserted by the Issuers, any Holder or any other Person) or liability in connection with the exercise or performance of any of its powers or duties hereunder and under the other Note Documents, except to the extent any such loss, liability or expense shall be determined to have been caused by the Trustee’s or Collateral Trustee’s, as the case may be, own gross negligence or willful misconduct (as determined by a final, non-appealable order of a court of competent jurisdiction). The Trustee will notify the Issuers promptly of any claim for which it may seek indemnity. Failure by the Trustee to so notify the Issuers will not relieve the Issuers of their obligations hereunder. The Issuers will defend the claim and the Trustee will cooperate in the defense. The Trustee and Collateral Trustee may have separate counsel and the Issuers will pay the reasonable fees and expenses of such counsel. The Issuers need not pay for any settlement made without their consent, which consent will not be unreasonably withheld.

75

(c) The obligations of the Issuers under this Section 7.06 will survive the satisfaction and discharge of this Indenture or the resignation or removal of the Trustee or the Collateral Trustee.

(d) To secure the Issuers’ payment obligations in this Section 7.06, the Trustee will have a Lien prior to the Notes on all money or property held or collected by the Trustee, except that held in trust to pay principal of, premium on, if any, or interest, if any, on, particular Notes. Such Lien will survive the satisfaction and discharge of this Indenture. The Trustee’s and Collateral Trustee’s respective right to receive payment of any amounts due under this Section 7.06 shall not be subordinate to any other liability or Indebtedness of the Issuers.

(e) When the Trustee incurs expenses or renders services after an Event of Default specified in Section 6.01(g) or (h) 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.

(f) “Trustee” or “Collateral Trustee” for purposes of this Section shall include any predecessor Trustee or Collateral Trustee; provided, however, that the gross negligence or willful misconduct of any Trustee or Collateral Trustee hereunder shall not affect the rights of any other Trustee or Collateral Trustee hereunder.

Section 7.07 Replacement of Trustee.

(a) A resignation or removal of the Trustee and appointment of a successor Trustee will become effective only upon the successor Trustee’s acceptance of appointment as provided in this Section 7.07.

(b) The Trustee may resign in writing at any time upon 30 days’ written notice to the Issuers and be discharged from the trust hereby created by so notifying the Issuers. The Holders of a majority in aggregate principal amount of the then outstanding Notes may remove the Trustee with respect to such Notes by so notifying the Trustee and the Issuers in writing. The Issuers may remove the Trustee if:

(1) the Trustee fails to comply with Section 7.09 hereof;

(2) the Trustee is adjudged a bankrupt or an insolvent or an order for relief is entered with respect to the Trustee under any Bankruptcy Law;

(3) a custodian or public officer takes charge of the Trustee or its property; or

(4) the Trustee becomes incapable of acting.

(c) If the Trustee resigns or is removed or if a vacancy exists in the office of Trustee for the Notes for any reason, the Issuers will promptly appoint a successor Trustee of the Notes. Within one year after the successor Trustee takes office, the Holders of a majority in aggregate principal amount of the then outstanding Notes may appoint a successor Trustee to replace the successor Trustee appointed by the Issuers.

(d) If a successor Trustee does not take office within 60 days after the retiring Trustee resigns or is removed, the retiring Trustee, the Issuers, or the Holders of at least 10% in aggregate principal amount of the then outstanding Notes may petition any court of competent jurisdiction for the appointment of a successor Trustee.

ARTICLE VIII.

LEGAL DEFEASANCE AND COVENANT DEFEASANCE

Section 8.01 Option to Effect Legal Defeasance or Covenant Defeasance.

The Issuers may at any time, at the option of their respective Boards of Directors evidenced by a resolution set forth in an Officer’s Certificate of the Main Issuer, elect to have either Section 8.02 or Section 8.03 hereof be applied to the outstanding Notes upon compliance with the conditions set forth below in this Article VIII.

Section 8.02 Legal Defeasance and Discharge.

Upon the Issuers’ exercise under Section 8.01 hereof of the option applicable to this Section 8.02, the Issuers will, subject to the satisfaction of the conditions set forth in Section 8.04 hereof, be deemed to have been discharged from their obligations with respect to all outstanding Notes on the date the conditions set forth below are satisfied (hereinafter, “Legal Defeasance”). For this purpose, Legal Defeasance means that the Issuers will be deemed to have paid and discharged the entire Debt represented by the outstanding Notes, which will thereafter be deemed to be “outstanding” only for the purposes of Section 8.05 hereof and the other Sections of this Indenture referred to in clauses (1) and (2) below, and to have satisfied all their other obligations under such Notes and this Indenture (and the Trustee, on demand of and at the expense of the Issuers, shall execute such instruments reasonably requested by the Issuers acknowledging the same), except for the following provisions which will survive until otherwise terminated or discharged hereunder:

(1) the rights of Holders of outstanding Notes to receive payments in respect of the principal of, or interest or premium, if any, on, such Notes when such payments are due from the trust referred to in Section 8.04 hereof;

(2) the Issuers’ obligations with respect to such Notes under Article II and Section 4.02 hereof;

(3) the rights, powers, trusts, duties, immunities and indemnities of the Trustee and the Collateral Trustee, and the Issuers’ obligations in connection therewith; and

(4) this Article VIII.

Subject to compliance with this Article VIII, the Issuers may exercise their option under this Section 8.02 notwithstanding the prior exercise of its option under Section 8.03 hereof.

Section 8.03 Covenant Defeasance.

Upon the Issuers’ exercise under Section 8.01 hereof of the option applicable to this Section 8.03, the Issuers and Peabody, as applicable, will, subject to the satisfaction of the conditions set forth in Section 8.04 hereof, be released from each of their obligations under the covenants contained in Sections 4.03, 4.07, 4.08, 4.09, 4.10, 4.11, 4.12, 4.13, 4.15, 4.16, 4.17, 4.18, 4.19, 4.20, 4.21 and 4.22 hereof and Section 5.01(c) 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

77

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, the Issuers’ may omit to comply with and will 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 with respect to the Notes, but, except as specified above, the remainder of this Indenture and such Notes will be unaffected thereby. In addition, upon the Issuers’ 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(c), (d), (e), (f), (i), (j), (k), (l) and (m) hereof will not constitute Events of Default with respect to the Notes.

in either case to the effect that, and based thereon such Opinion of Counsel will confirm that, the beneficial owners of the outstanding Notes will not recognize income, gain or loss for federal income tax purposes as a result of such Legal Defeasance and will be subject to federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Legal Defeasance had not occurred;

(3) in the case of an election under Section 8.03 hereof, the Issuers must deliver to the Trustee an Opinion of Counsel confirming that the beneficial owners of the outstanding Notes will not recognize income, gain or loss for federal income tax purposes as a result of such Covenant Defeasance and will be subject to federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Covenant Defeasance had not occurred;

78

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

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 will be held in trust and applied by the Trustee, in accordance with the provisions of such Notes and this Indenture, to the payment, either directly or through any Paying Agent (including the Issuers 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, if any, but such money need not be segregated from other funds except to the extent required by law.

Notwithstanding anything in this Article VIII to the contrary, the Trustee will deliver or pay to the Issuers from time to time upon the written request of the Issuers 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 the Issuers.

Subject to applicable abandoned property law, any money deposited with the Trustee or any Paying Agent, or then held by the Issuers, in trust for the payment of the principal of, premium on, if any, or interest, if any, on, any Note and remaining unclaimed for two years after such principal, premium, if any, or interest, if any, has become due and payable shall be paid to the Issuers on its request or (if then held by the Issuers) will be discharged from such trust; and the Holder of such Note will thereafter be permitted to look only to the Issuers for payment thereof, and all liability of the Trustee or such Paying Agent with respect to such trust money, and all liability of the Issuers 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 Issuers 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 will be repaid to the Issuers.

79

make any payment of principal of, premium on, if any, or interest, if any, on, any Note following the reinstatement of its obligations, the Issuers will 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.

80

Section 9.02 With Consent of Holders.

Except as provided below in this Section 9.02, the Issuers, the Trustee and Collateral Trustee, as applicable, may amend or supplement this Indenture, the Notes and the other Note Documents with the consent of the Holders of at least 66.67% in aggregate principal amount of the Notes then outstanding, and, subject to Section 6.04 and Section 6.07 hereof, compliance with any provision of this Indenture or the Notes may be waived with the consent of the Holders of at least 66.67% in aggregate principal amount of the then outstanding Notes. For the avoidance of doubt, any existing Default or Event of Default may, by notice to the Trustee, be waived by the Holders of a majority in aggregate principal amount of the outstanding Notes in accordance with Section 6.04 hereof.

Upon the request of the Issuers accompanied by a resolution of their respective Board of Directors authorizing the execution of any such amended or supplemental indenture or amendment or supplement to any Note Document, and upon the filing with the Trustee and Collateral Trustee, if applicable, of evidence satisfactory to the Trustee of the consent of the Holders as aforesaid, and upon receipt by the Trustee and Collateral Trustee, if applicable, of the documents described in Section 9.05 hereof, the Trustee and Collateral Trustee, if applicable, shall join with the Issuers in the execution of such amended or supplemental indenture or amendment or supplement to any Note Document unless such amended or supplemental indenture or amendment or supplement to such Note Document affects the Trustee’s or Collateral Trustee’s own rights, duties or immunities under this Indenture or otherwise, in which case each of the Trustee and Collateral Agent may in its discretion, but shall not be obligated to, enter into such amended or supplemental indenture or amendment or supplement to such Note Document.

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

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

Subject to Section 6.04 and Section 6.07 hereof, the Holders of at least 66.67% in aggregate principal amount of the Notes then outstanding may waive compliance in a particular instance by the Issuers with any provision of this Indenture or the Notes.

Notwithstanding other provisions of this Section 9.02, unless consented to by the Holders of at least 85.00% of the aggregate principal amount of the then outstanding Notes, an amendment, supplement or waiver under this Section 9.02 may not (i) release the Liens for the benefit of the Holders of the Notes on all or substantially all of the Collateral, (ii) alter or waive the provisions with respect to the redemption of the Notes described under Section 4.10, Section 4.14, Section 4.16 and Section 4.18 or (iii) modify or change any provision of this Indenture affecting the ranking of the Notes in a manner materially adverse to the Holders of the Notes.

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

(1) reduce the principal amount of or change the Stated Maturity of any installment of principal of any Note or alter or waive the provisions with respect to the redemption of the Notes (other than the provisions described under Section 4.10, Section 4.14 and Section 4.16);

81

(2) reduce the rate of or change the Stated Maturity of any interest payment on any Note;

(3) reduce the amount payable upon the redemption of any Note or, in respect of an optional redemption, the times at which any Note may be redeemed;

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

(6) impair the right of any Holder of Notes to receive any principal payment or interest payment on such Holder’s Notes, on or after the Stated Maturity thereof, or institute suit for the enforcement of any such payment;

(7) make any change in the percentage of the principal amount of the Notes whose Holders must consent to an amendment or waiver;

(8) [reserved];

(9) [reserved];

(10) modify or amend the provisions in this Indenture regarding the waiver of past Defaults and the waiver of certain covenants by the Holders of such Notes affected thereby, except to increase any percentage vote required or to provide that certain other provisions of this Indenture may not be modified or waived without the consent of the Holder of each Note affected thereby; or

(11) modify or amend any of the above or this amendment and waiver provision.

Neither the Issuers nor any of their Subsidiaries or Affiliates may, directly or indirectly, pay or cause to be paid any consideration, whether by way of interest, fee or otherwise, to any Holder for or as an inducement to any consent, waiver or amendment of any of the terms or provisions of this Indenture or the Notes unless such consideration is offered to be paid or agreed to be paid to all Holders that consent, waive or agree to amend such term or provision within the time period set forth in the solicitation documents relating to the consent, waiver or amendment.

For the avoidance of doubt, no amendment to, or deletion of any of the covenants described in Article IV hereof, in each case in accordance with the provisions governing such amendment or deletion contained in this Indenture, or action taken in compliance with such covenants in effect at the time of such action, shall be deemed to impair or affect any legal rights of any Holders to receive payment of principal of or premium, if any, or interest on the Notes or to institute suit for the enforcement of any payment on or with respect to such Holder’s Notes.

Section 9.03 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 and the Issuers receive written notice of revocation before the date the waiver, supplement or amendment becomes effective. An amendment, supplement or waiver becomes effective in accordance with its terms and thereafter binds every Holder.

The Issuers may, but shall not be obligated to, fix a record date for the purpose of determining the Holders entitled to consent to any amendment, supplement or waiver. If a record date is fixed, then notwithstanding the last sentence of the immediately preceding paragraph, those Persons who were Holders at such record date (or their duly designated proxies), and only those Persons, shall be entitled to consent to such amendment, supplement or waiver or revoke any consent previously given, whether or not such Persons continue to be Holders after such record date. No consent shall be valid or effective for more than 90 days after such record date except to the extent that the

82

requisite number of consents to the amendment, supplement or waiver have been obtained within such 90-day period or as set forth in the next paragraph of this Section 9.03.

After an amendment, supplement or waiver becomes effective, it shall bind every Holder, unless it makes a change described in any of clauses (1) through (11) of Section 9.02 hereof, in which case, the amendment, supplement or waiver shall bind only each Holder of a Note who has consented to it and every subsequent Holder of a Note or portion of a Note that evidences the same indebtedness as the consenting Holder’s Note.

Section 9.04 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 Issuers, in exchange for all Notes, may issue and the Trustee, upon receipt of an Issuers Order, shall authenticate new Notes that reflect the amendment, supplement or waiver. Failure to make the appropriate notation or issue a new Note shall not affect the validity and effect of such amendment, supplement or waiver.

Section 9.05 Trustee to Sign Amendments, etc.

The Trustee and Collateral Trustee shall sign any amended or supplemental indenture or amendment or supplement to a Note Document, as applicable, authorized pursuant to this Article IX if the amendment or supplement does not adversely affect the rights, duties, liabilities or immunities of the Trustee or Collateral Trustee. In executing any amended or supplemental indenture or amendment or supplement to any Note Document, the Trustee and Collateral Trustee shall be entitled to receive and (subject to Section 7.01 hereof) shall be fully protected in relying upon, an Officer’s Certificate of the Main Issuer and an Opinion of Counsel stating that the execution of such amendment or supplement is authorized or permitted by this Indenture, the Collateral Trust Agreement and the other Note Documents and that all conditions precedent to the execution and delivery of such amendments or supplements have been satisfied.

Section 9.06 Effect of Supplemental Indentures.

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

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

Failing payment when due of any amount so guaranteed or any performance so guaranteed for whatever reason, the Guarantors will be jointly and severally obligated to pay the same immediately. Each Guarantor agrees that this is a continuing 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 this 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 Issuers, 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, marshaling, filing of claims with a court in the event of insolvency or bankruptcy of either of the Issuers, any right to require a proceeding first against either of the Issuers, protest, notice and all demands whatsoever and covenant that this Note Guarantee will not be subject to any impairment, set off, defense, counterclaim or discharge except by complete performance of the obligations contained in the Notes and this Indenture. Without limiting the generality of the foregoing, this Note Guarantee and the obligations of each Guarantor hereunder shall not be affected by, and each Guarantor hereby waives all rights, claims or defenses that it might otherwise have with respect to:

(1) any renewal, extension or acceleration of, or any increase in the amount of the obligations hereunder, or any amendment, supplement, modification or waiver of, or any consent to departure from, this Indenture;

(2) any change, reorganization or termination of the corporate structure or existence of the Issuers or any other Guarantor or any of their Subsidiaries and any corresponding restructuring of the obligations hereunder; or

(3) the validity, perfection, non-perfection or lapse in perfection, priority or avoidance of any security interest or lien, the release of any or all Collateral securing, or purporting to secure, the Obligations hereunder or any other impairment of such Collateral.

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

(d) Each Guarantor agrees that any right of subrogation, reimbursement or contribution it may have in relation to the Holders or in respect of any obligations guaranteed hereby shall be subordinated to, and shall not be enforceable 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, the Trustee and the Collateral Trustee, on the other hand, (1) the maturity of the obligations guaranteed hereby may be accelerated as provided in Article VI hereof for the purposes of this Note 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 VI hereof, such obligations (whether or not due and payable) will forthwith become due and payable by the Guarantors for the purpose of this Note 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, the Trustee or the Collateral Trustee under the Note 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 Note 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 Note 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 X, result in the obligations of such Guarantor under its Note Guarantee not constituting a fraudulent transfer or conveyance.

Section 10.03 Execution and Delivery of Note Guarantee.

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

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

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

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

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

(2) in respect of subclause (B) of clause (1) of this Section 11.01, 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/or any similar deposit relating to other Debt and, in each case, the granting of Liens to secure such borrowings) and the deposit will not result in a breach or violation of, or constitute a default under, any other instrument to which the Issuers are a party or by which the Issuers are bound (other than with respect to the borrowing of funds to be applied concurrently to make the deposit required to effect such satisfaction and discharge and any similar concurrent deposit relating to other Debt, and in each case the granting of Liens to secure such borrowings);

(3) the Issuers have paid or caused to be paid all sums payable by it under this Indenture with respect to the Notes; and

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

The Collateral will be released from the Lien securing the Notes, as provided in Section 12.04 hereof in accordance with this Article XI.

Notwithstanding the satisfaction and discharge of this Indenture with respect to the Notes, if money has been deposited with the Trustee pursuant to subclause (B) of clause (1) of this Section 11.01, the provisions of Sections 11.02 and 8.06 hereof will survive with respect to the Notes. In addition, nothing in this Section 11.01 will be deemed to discharge those provisions of Section 7.06 hereof, that, by their terms, survive the satisfaction and discharge of this Indenture.

Section 11.02 Application of Trust Money.

Subject to the provisions of Section 8.06 hereof, all money or Government Securities 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 this Indenture, to the payment, either directly or through any Paying Agent (including the Issuers acting as their own Paying Agent) as the Trustee may determine, to the Persons entitled thereto, of the principal,

86

premium, if any, and interest, if any, 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 Issuers’ obligations under this 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 Issuers have made any payment of principal of, premium on, if any, or interest, if any, on, any Notes because of the reinstatement of its obligations, the Issuers 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.

90

of the written consent of the Holders of a majority in aggregate principal amount of the outstanding Notes (or the minimum consent for such action required under this Indenture) along with security and indemnity satisfactory to the Trustee and the Collateral Trustee, shall take such actions; provided, that upon the receipt by the Trustee and Collateral Trustee of a written request of the Issuers signed by an Officer (a “Security Document Order”), the Trustee and Collateral Trustee are hereby authorized to execute and enter into, and shall execute and enter into, without the further consent of any Holder or the Trustee and without liability to any Person, any Security Document to which it is a party or amendment or supplement thereto to be executed after the Issue Date; provided, further, that neither the Trustee nor the Collateral Trustee shall be required to execute or enter into any such Security Document which, in the Trustee’s or Collateral Trustee’s reasonable opinion is reasonably likely to adversely affect the rights, duties, liabilities or immunities of the Trustee or Collateral Trustee, as the case may be, or that the Trustee or Collateral Trustee determines is reasonably likely to involve the Trustee or Collateral Trustee in personal liability. Such Security Document Order shall (i) state that it is being delivered to the Trustee and Collateral Trustee pursuant to, and is a Security Document Order referred to in, this Indenture and (ii) instruct the Trustee to execute and enter into (or direct the Collateral Trustee to execute and enter into) such Security Document. Other than as set forth in this Indenture, any such execution of a Security Document shall be at the direction and expense of the Issuers, upon delivery to the Trustee and Collateral Trustee of an Officer’s Certificate and Opinion of Counsel stating that all conditions precedent in the Indenture and the other Note Documents to the execution and delivery of the Security Document have been satisfied.

(c) The rights, privileges, protections, immunities and benefits given to the Trustee under this Indenture, including, without limitation, its right to be indemnified and compensated and all other rights, privileges, protections, immunities and benefits set forth in this Indenture are extended to the Trustee when acting under the Collateral Trust Agreement and the other Note Documents on behalf of the Holders.

(d) The Trustee will not be responsible for filing any financing or continuation statements or recording any documents or instruments in any public office at any time or times or otherwise perfecting or maintaining the perfection of any Liens on the Collateral.

(e) Whenever an action under the Collateral Trust Agreement requires an Act of Required Secured Parties, the Trustee, in its capacity as Priority Lien Representative, shall be entitled to seek the direction of Holders of the Notes. Subject to the next succeeding sentence, if the minimum consent or directions of Holders for such action required by Sections 6.05 or 9.02 or otherwise under this Indenture are met, the Trustee shall deliver a written direction to the Collateral Trustee (i) directing such Act of Required Secured Parties and (ii) notifying the Collateral Trustee of the aggregate principal amount of the Notes consenting or directing such action (it being agreed that if the requisite percentage of consent or direction is received by the Trustee, the Trustee shall consent or direct such action on behalf of all of the then outstanding aggregate principal amount of the Notes), which upon request of the Collateral Trustee, shall be accompanied by indemnity or security acceptable to the Collateral Trustee for any losses, liability or expenses that may be incurred in connection with such direction (it being understood that the Trustee, in its individual capacity, shall not be obligated to provide such indemnity or security).

For purposes of determining the consent or direction of Holders for an action under the Collateral Trust Agreement that requires an Act of Required Secured Parties, the Notes registered in the name of, or beneficially owned by, the Issuers or any Affiliate of the Issuers will be deemed not to be outstanding and neither the Issuers nor any Affiliate of the Issuers will be entitled to vote such Notes and the Issuers shall notify the Trustee and the Collateral Trustee in writing whether any Notes are owned by the Issuers or any of their Affiliates.
