An authenticating agent has the same rights as any Registrar, co-Registrar Transfer Agent or Paying Agent to deal with the Issuer or an Affiliate of the Issuer. The Trustee shall have the right to decline to authenticate and deliver any Notes under this Section 2.02 if the Trustee, being advised by counsel, determines that such action may not lawfully be taken or if the Trustee in good faith shall determine that such action would expose the Trustee to personal liability to existing Holders. SECTION 2.03. Registrar, Transfer Agent and Paying Agent. The Issuer shall maintain an office or agency for the registration of the Notes and of their transfer or exchange (the "Registrar"), an office or agency where Notes may be transferred or exchanged (the "Transfer Agent"), an office or agency where the Notes may be presented for payment (the "Paying Agent") and an office or agency where notices or demands to or upon the Issuer in respect of the Notes may be served.

Subject to any applicable laws and regulations, the Issuer shall cause the Registrar to keep a register (the "Security Register") at its corporate trust office in which, subject to such reasonable regulations it may prescribe, the Issuer shall provide for the registration of ownership, exchange, and transfer of the Notes. Such registration in the Security Register shall be conclusive evidence of the ownership of Notes.

In the case of the replacement of any of the Notes, the Registrar shall keep a record of the Note so replaced and the Note issued in replacement thereof. In the case of the cancellation of any of the Notes, the Registrar shall keep a record of the Note so canceled and the date on which such Note was canceled.

The agreement shall implement the provisions of this Indenture that relate to such agent. The Issuer shall notify the Trustee of the name and address of any such agent. If the Issuer fails to maintain a Registrar or Paying Agent, the Trustee shall act as such and shall be entitled to appropriate compensation therefor pursuant to Section 7.07 of this Indenture.

The Issuer at any time may require a Paying Agent to pay all money held by it to the Trustee and account for any funds disbursed, and the Trustee may at any time during the continuance of any payment default, upon written request to a Paying Agent, require such Paying Agent to pay all money held by it to the Trustee and to account for any funds disbursed. Upon doing so, the Paying Agent shall have no further liability for the money so paid over to the Trustee. If the Issuer or any Affiliate of the Issuer acts as Paying Agent, it will, on or before each due date of any principal, premium, if any, or interest on the Notes, segregate and hold in a separate trust fund for the benefit of the Holders a sum of money sufficient to pay such principal, premium, if any, or interest so becoming due until such sum of money shall be paid to such Holders or otherwise disposed of as provided in this Indenture, and will promptly notify the Trustee of its action or failure to act.

To permit registrations of transfers and exchanges, the Issuer shall execute and the Trustee shall authenticate and deliver, in the name of the designated transferee or transferees, one or more new Notes, of any authorized denominations and of a like aggregate principal amount, at the Registrar's request. No service charge shall be made for any registration of transfer or exchange of Notes (except as otherwise expressly permitted herein), but the Issuer may require payment of a sum sufficient to cover any agency fee or similar charge payable in connection with any such registration of transfer or exchange of Notes (other than any agency fee or similar charge payable upon exchanges pursuant to Sections 2.10, 3.08 or 9.05) or in accordance with an Excess Proceeds Offer pursuant to Section 4.09 or Change of Control Offer pursuant to Section 4.11, not involving a transfer.

No exchange or transfer of a Note shall be effective under this Indenture unless and until such Note has been registered in the name of such Person in the Security Register. Furthermore, the exchange or transfer of any Note shall not be effective under this Indenture unless the request for such exchange or transfer is made by the Holder or by a duly authorized attorney-in-fact at the office of the Registrar. Every Note presented or surrendered for registration of transfer or for exchange shall (if so required by the Issuer or the Registrar) be duly endorsed, or be accompanied by a written instrument or transfer, in form satisfactory to the Issuer and the Registrar, duly executed by the Holder thereof or his attorney duly authorized in writing. All Notes issued upon any registration of transfer or exchange of Notes shall be the valid obligations of the Issuer evidencing the same indebtedness, and entitled to the same benefits under this Indenture, as the Notes surrendered upon such registration of transfer or exchange. 34 In the event that the Issuer delivers to the Trustee a copy of an Officers' Certificate certifying that a registration statement under the Securities Act with respect to the Exchange Offer, or a Shelf Registration Statement, as the case may be, has been declared effective by the SEC, and that the Issuer has offered Exchange Notes to the Holders in accordance with the Exchange Offer or that Notes have been offered pursuant to such Shelf Registration Statement, the Trustee shall exchange or issue upon transfer, as the case may be, upon request of any Holder, such Holder's Notes for (i) in the case of an Exchange Offer, Exchange Notes upon the terms set forth in the Exchange Offer or (ii) in the case of a transfer pursuant to a Shelf Registration Statement, Notes that comply with the requirements applicable following such a transfer as set forth in Section 2.01(c). The Issuer shall not be required (i) to issue, register the transfer of, or exchange any Note during a period beginning at the opening of 15 Business Days before the day of the mailing of a notice of redemption of Notes selected for redemption under Section 3.02 and ending at the close of business on the day of such mailing, or (ii) to register the transfer of or exchange any Note so selected for redemption in whole or in part, except the unredeemed portion of any Note being redeemed in part. (b) Notwithstanding any provision to the contrary herein, so long as a Global Note remains outstanding and is held by or on behalf of the Depositary, transfers of a Global Note, in whole or in part, or of any beneficial interest therein, shall only be made in accordance with Section 2.01(d), Section 2.06(a) and this Section 2.06(b); provided, however, that a beneficial interest in a Global Note may be transferred to Persons who take delivery thereof in the form of a beneficial interest in the same Global Note in accordance with the transfer restrictions set forth in the restricted Note legend on the Note, if any. (i) Except for transfers or exchanges made in accordance with any of clauses (ii), (iii), (iv) or (v) of this Section 2.06(b), transfers of a Global Note shall be limited to transfers of such Global Note in whole, but not in part, to nominees of the Depositary or to a successor of the Depositary or such successor's nominee. (ii) Restricted Global Note to Regulation S Global Note. If the Holder of a beneficial interest in the Restricted Global Note at any time wishes to exchange its interest in such Restricted Global Note for an interest in the Regulation S Global Note, or to transfer its interest in such Restricted Global Note to a Person who wishes to take delivery thereof in the form of a beneficial interest in the Regulation S Global Note, such transfer or exchange may be effected, only in accordance with this clause (ii) and the rules and procedures of the Depositary. Upon receipt by the Registrar from the Transfer Agent of (A) instructions directing the Registrar to credit or cause to be credited an interest in the Regulation S Global Note in a specified principal amount and to cause to be debited an interest in the Restricted Global Note in such specified principal amount, and (B) a certificate in the form of Exhibit B attached hereto given by the Holder of such beneficial interest stating that the transfer of such interest has been made in compliance with the transfer restrictions applicable to the Global Notes and (x) pursuant to and in accordance with Regulation S or (y) that the Note being transferred is being transferred in a transaction permitted by Rule 144, then the Registrar shall instruct the Depositary to reduce or cause to be reduced the principal amount of the Restricted Global Note and to 35 increase or cause to be increased the principal amount of the Regulation S Global Note by the aggregate principal amount of the interest in the Restricted Global Note to be exchanged. (iii) Regulation S Global Note to Restricted Global Note. If the Holder of a beneficial interest in the Regulation S Global Note at any time wishes to transfer such interest to a Person who wishes to take delivery thereof in the form of a beneficial interest in the Restricted Global Note, such transfer may be effected only in accordance with this clause (iii) and the rules and procedures of the Depositary. Upon receipt by the Registrar from the Transfer Agent of (A) instructions directing the Registrar to credit or cause to be credited an interest in the Restricted Global Note in a specified principal amount and to cause to be debited an interest in the Regulation S Global Note in such specified principal amount, and (B) a certificate in the form of Exhibit C attached hereto given by the Holder of such beneficial interest stating that the transfer of such interest has been made in compliance with the transfer restrictions applicable to the Global Notes and stating that (x) the Person transferring such Interest reasonably believes that the Person acquiring such interest is a QIB and is obtaining such interest in a transaction meeting the requirements of Rule 144A and any applicable securities laws of any state of the United States or (y) that the Person transferring such interest is relying on an exemption other than Rule 144A from the registration requirements of the Securities Act and, in such circumstances, such Opinion of Counsel as the Issuer or the Trustee may reasonably request to ensure that the requested transfer or exchange is being made pursuant to an exemption from, or in a transaction not subject to, the registration requirements of the Securities Act, then the Registrar shall instruct the Depositary to reduce or cause to be reduced the principal amount of the Regulation S Global Note and to increase or cause to be increased the principal amount of the Restricted Global Note by the aggregate principal amount of the interest in the Regulation S Global Note to be exchanged or transferred. (iv) Restricted Global Note to Exchange Global Note. Following the earlier of the consummation of the Exchange Offer or the transfer of a Note pursuant to a Shelf Registration Statement that results in beneficial interests in such Note being reflected in the Exchange Global Note, if the Holder of a beneficial interest in the Restricted Global Note at any time wishes to exchange its interest in such Restricted Global Note for an interest in the Exchange Global Note, or to transfer its interest in such Restricted Global Note to a Person who wishes to take delivery thereof in the form of a beneficial interest in the Regulation S Global Note, such transfer or exchange, if not effected pursuant to Section 2.06(a) may be effected only in accordance with this clause (iv) and the rules and procedures of the Depositary. Upon receipt by the Registrar from the Transfer Agent of (A) instructions directing the Registrar to credit or cause to be credited an interest in the Exchange Global Note in a specified principal amount and to cause to be debited an interest in the Restricted Global Note in such specified principal amount, and (B) a certificate in the form of Exhibit B attached hereto given by the Holder of such beneficial interest stating that the transfer of such interest has been made in compliance with the transfer restrictions applicable to the Global Notes and (x) pursuant to and in accordance with Regulation S or (y) that the Note being transferred is being transferred in a transaction permitted by Rule 144, then the Registrar shall instruct the Depositary to 36 reduce or cause to be reduced the principal amount of the Restricted Global Note and to increase or cause to be increased the principal amount of the Regulation S Global Note by the aggregate principal amount of the interest in the Restricted Global Note to be exchanged or transferred. (v) Regulation S Global Note to Exchange Global Note. Following the earlier of the consummation of the Exchange Offer or the transfer of a Note pursuant to a Shelf Registration Statement that results in beneficial interests in such Note being reflected in the Exchange Global Note, if the Holder of a beneficial interest in the Regulation S Global Note at any time wishes to exchange its interest in such Regulation S Global Note for an interest in the Exchange Global Note, or to transfer its interest in such Regulation S Global Note to a Person who wishes to take delivery thereof in the form of a beneficial interest in the Exchange Global Note, such transfer or exchange, if not effected pursuant to an Exchange Offer or a Shelf Registration Statement in accordance with Section 2.06(a) may be effected only in accordance with this clause (v) and the rules and procedures of the Depositary. Upon receipt by the Registrar from the Transfer Agent of instructions directing the Registrar to credit or cause to be credited an interest in the Exchange Global Note in a specified principal amount and to cause to be debited an interest in the Regulation S Global Note in such specified principal amount, then the Registrar shall instruct the Depositary to reduce or cause to be reduced the principal amount of the Regulation S Global Note and to increase or cause to be increased the principal amount of the Exchange Global Note by the aggregate principal amount of the interest in the Regulation S Global Note to be exchanged or transferred. (vi) Global Notes to Certificated Notes. In the event that a Global Note is exchanged for Notes in certificated, registered form pursuant to Section 2.10, the effectiveness of a Shelf Registration Statement with respect to such Notes, such Notes may be exchanged only in accordance with such procedures as are substantially consistent with the provisions of clauses (ii) and (iii) above (including the certification requirements intended to ensure that such transfers comply with Rule 144A or Regulation S under the Securities Act, as the case may be) and such other procedures as may from time to time be adopted by the Issuer and the Trustee. (c) Except in connection with an Exchange Offer or a Shelf Registration Statement contemplated by and in accordance with the terms of the Registration Rights Agreement, if Notes are issued upon the transfer, exchange or replacement of Notes bearing the restricted Notes legends set forth in Exhibit A hereto, the Notes so issued shall bear the restricted Notes legends, and a request to remove such restricted Notes legends from Notes will not be honored unless there is delivered to the Issuer such satisfactory evidence, which may include an Opinion of Counsel licensed to practice law in the State of New York, as may be reasonably required by the Issuer, that neither the legend nor the restrictions on transfer set forth therein are required to ensure that transfers thereof comply with the provisions of Rule 144A or Rule 144(k) under the Securities Act. Upon provision of such satisfactory evidence, the Trustee, at the direction of the Issuer, shall authenticate and deliver Notes that do not bear the legend. (d) The Trustee shall have no responsibility for any actions taken or not taken by the Depositary, for any Depositary records or beneficial ownership interests or for any transactions 37 between the Depositary and any Agent Member or between or among the Depositary, a participant and/or any holder or owner of a beneficial interest in a Global Note. (e) The Trustee shall have no obligation or duty to monitor, determine or inquire as to compliance with any restrictions on transfer imposed under this Indenture or under applicable law with respect to any transfer of any interest in any Notes (including any transfers between or among the Depositary's participants or beneficial owners of interests in any Global Note) other than to require delivery of such certificates and other documentation, including delivery of Opinions of Counsel, as is expressly required by, and to do so if and when expressly required by, the terms of this Indenture and to examine the same to determine substantial compliance as to form with the express requirements hereof. SECTION 2.07. Replacement Notes. If a mutilated certificated Note is surrendered to the Registrar or if the Holder claims that the Note has been lost, destroyed or wrongfully taken, the Issuer shall issue and the Trustee shall authenticate a replacement Note in such form as the Note mutilated, lost, destroyed or wrongfully taken if the Holder satisfies any other reasonable requirements of the Trustee or the Issuer. If required by the Trustee or the Issuer, such Holder shall furnish an indemnity or indemnity bond sufficient in the judgment of the Issuer and the Trustee to protect the Issuer, the Trustee, the Paying Agent, the Transfer Agent, the Registrar and any co-Registrar, and any authenticating agent from any loss that any of them may suffer if a Note is replaced. The Issuer and the Trustee may charge the Holder for their expenses in replacing a Note. Every replacement Note shall be an additional obligation of the Issuer. SECTION 2.08. Outstanding Notes. Notes outstanding at any time are all Notes authenticated by the Trustee except for those cancelled by it, those delivered to it for cancellation and those described in this Section 2.08 as not outstanding. A Note does not cease to be outstanding because the Issuer or an Affiliate of the Issuer holds the Note. If a Note is replaced pursuant to Section 2.07, it ceases to be outstanding unless the Trustee and the Issuer receive proof satisfactory to them that the Note which has been replaced is held by a bona fide purchaser. If the Paying Agent segregates and holds in trust, in accordance with this Indenture, on a Redemption Date or maturity date money sufficient to pay all principal, premium, if any, interest payable on that date with respect to the Notes (or portions thereof) to be redeemed or maturing, as the case may be, and the Paying Agent is not prohibited from paying such money to the Holders on that date pursuant to the terms of this Indenture, then on and after that date such Notes (or portions thereof) cease to be outstanding and interest on them ceases to accrue. SECTION 2.09. Notes Held by Issuer. In determining whether the Holders of the required principal amount of Notes have concurred in any direction or consent or any amendment, modification or other change to this Indenture, Notes owned by the Issuer or by an Affiliate of the Issuer shall be disregarded and treated as if they were not outstanding, except that for the purposes of determining whether the Trustee shall be protected in relying on any such direction, waiver or consent or any amendment, modification or other change to this Indenture, 38 only Notes which a Trust Officer of the Trustee actually knows are so owned shall be so disregarded. Notes so owned which have been pledged in good faith shall not be disregarded if the pledgee establishes to the satisfaction of the Trustee the pledgee's right so to act with respect to the Notes and that the pledgee is not the Issuer or an Affiliate of the Issuer. SECTION 2.10. Certificated Notes. (a) A Global Note deposited with the Depositary or other custodian for the Depositary pursuant to Section 2.01 shall be transferred to the beneficial owners thereof in the form of certificated Notes only if such transfer complies with Section 2.06 and (i) the Depositary notifies the Issuer that it is unwilling or unable to continue as the Depositary for such Global Note, or if at any time the Depositary ceases to be a "clearing agency" registered under the Exchange Act and a successor depositary is not appointed by the Issuer within 90 days of such notice, or (ii) the Issuer, at its option, executes and delivers to the Trustee a notice that such Global Note be so transferable, registrable and exchangeable, or (iii) an Event of Default, or an event which after notice or lapse of time or both would be an Event of Default, has occurred and is continuing with respect to the Notes or (iv) the issuance of such certificated Notes is necessary in order for a Holder or beneficial owner to present its Note or Notes to a Paying Agent in order to avoid any tax that is imposed on or with respect to a payment made to such Holder or beneficial owner. Notice of any such transfer shall be given by the Issuer in accordance with the provisions of Section 12.02(a). (b) Any Global Note that is transferable to the beneficial owners thereof in the form of certificated Notes pursuant to this Section 2.10 shall be surrendered by the Depositary to the Transfer Agent, to be so transferred, in whole or from time to time in part, without charge, and the Trustee shall authenticate and deliver, upon such transfer of each portion of such Global Note, an equal aggregate principal amount at maturity of Notes of authorized denominations in the form of certificated Notes. Any portion of a Global Note transferred or exchanged pursuant to this Section 2.10 shall be executed, authenticated and delivered only in registered form in denominations of $1,000 and any integral multiple thereof and registered in such names as the Depositary shall direct. Subject to the foregoing, a Global Note is not exchangeable except for a Global Note of like denomination to be registered in the name of the Depositary or its nominee. In the event that a Global Note becomes exchangeable for certificated Notes, payment of principal, premium, if any, and interest on the certificated Notes will be payable, and the transfer of the certificated Notes will be registrable, at the office or agency of the Issuer maintained for such purposes in accordance with Section 2.03. Such certificated Notes shall bear the applicable legends set forth in Exhibit A hereto. (c) In the event of the occurrence of any of the events specified in Section 2.10(a), the Issuer will promptly make available to the Trustee a reasonable supply of certificated Notes in definitive, fully registered form without interest coupons. SECTION 2.11. Cancellation. The Issuer at any time may deliver Notes to the Trustee for cancellation. The Registrar and the Paying Agent shall forward to the Trustee any Notes surrendered to them for registration of transfer, exchange or payment. The Trustee, in accordance with its customary procedures, and no one else shall cancel (subject to the record retention requirements of the Exchange Act and the Trustee's retention policy) all Notes surrendered for registration of transfer, exchange, payment or cancellation and dispose of such cancelled Notes in its customary manner. Except as otherwise provided in this Indenture the 39 Issuer may not issue new Notes to replace Notes it has redeemed, paid or delivered to the Trustee for cancellation. SECTION 2.12. Defaulted Interest. Any interest on any Note that is payable, but is not punctually paid or duly provided for, on the dates and in the manner provided in the Notes and this Indenture (all such interest herein called "Defaulted Interest") shall forthwith cease to be payable to the Holder on the relevant Record Date by virtue of having been such Holder, and such Defaulted Interest may be paid by the Issuer, at its election in each case, as provided in clause (a) or (b) below: (a) The Issuer may elect to make payment of any Defaulted Interest to the Persons in whose names the Notes are registered at the close of business on a special Record Date for the payment of such Defaulted Interest, which shall be fixed in the following manner. The Issuer shall notify the Trustee in writing of the amount of Defaulted Interest proposed to be paid on each Note and the date of the proposed payment, and at the same time the Issuer may deposit with the Trustee an amount of money equal to the aggregate amount proposed to be paid in respect of such Defaulted Interest; or shall make arrangements satisfactory to the Trustee for such deposit prior to the date of the proposed payment, such money when deposited to be held in trust for the benefit of the Persons entitled to such Defaulted Interest as in this clause provided. In addition, the Issuer shall fix a special Record Date for the payment of such Defaulted Interest, such date to be not more than 15 days and not less than 10 days prior to the proposed payment date and not less than 15 days after the receipt by the Trustee of the notice of the proposed payment date. The Issuer shall promptly but, in any event, not less than 15 days prior to the special Record Date, notify the Trustee of such special Record Date and, in the name and at the expense of the Issuer, the Trustee shall cause notice of the proposed payment date of such Defaulted Interest and the special Record Date therefor to be mailed first-class, postage prepaid to each Holder as such Holder's address appears in the Security Register, not less than 10 days prior to such special Record Date. Notice of the proposed payment date of such Defaulted Interest and the special Record Date therefor having been so mailed, such Defaulted Interest shall be paid to the Persons in whose names the Notes are registered at the close of business on such special Record Date and shall no longer be payable pursuant to clause (b) below. (b) The Issuer may make payment of any Defaulted Interest on the Notes in any other lawful manner not inconsistent with the requirements of any securities exchange on which the Notes may be listed, and upon such notice as may be required by such exchange, if, after notice given by the Issuer to the Trustee of the proposed payment date pursuant to this clause, such manner of payment shall be deemed reasonably practicable. Subject to the foregoing provisions of this Section 2.12, each Note delivered under this Indenture upon registration of transfer of or in exchange for or in lieu of any other Note shall carry the rights to interest accrued and unpaid, and to accrue, which were carried by such other Note. SECTION 2.13. Computation of Interest. Interest on the Notes shall be computed on the basis of a 360-day year of twelve 30-day months. 40 SECTION 2.14. CUSIP, ISIN and Common Code Numbers. The Issuer in issuing the Notes may use CUSIP, ISIN and Common Code numbers (if then generally in use), and, if so, the Trustee shall use CUSIP, ISIN and Common Code numbers, as appropriate, in notices of redemption as a convenience to Holders; provided, however, that any such notice may state that no representation is made as to the correctness of such numbers or codes either as printed on the Notes or as contained in any notice of a redemption and that reliance may be placed only on the other identification numbers printed on the Notes, and any such redemption shall not be affected by any defect in or omission of such numbers. The Issuer will promptly notify the Trustee of any change in the CUSIP, ISIN or Common Code numbers. SECTION 2.15. Issuance of Additional Notes and Exchange Notes. The Issuer may, subject to Section 4.06 of this Indenture, issue Additional Notes under this Indenture in accordance with the procedures of Section 2.02. The Original Notes issued on the date of this Indenture and any Additional Notes subsequently issued shall be treated as a single class for all purposes under this Indenture. ARTICLE THREE REDEMPTION; OFFERS TO PURCHASE SECTION 3.01. Optional Redemption. Except as set forth in the next paragraph, the Notes will not be redeemable at the option of the Issuer prior to July 1, 2008. Starting on that date, the Issuer may redeem all or any portion of the Notes, at once or over time, after giving the required notice under this Indenture. The Notes may be redeemed at the redemption prices set forth below, plus accrued and unpaid interest to 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). The following prices are for Notes redeemed during the 12-month period commencing on July 1, 2008 of the years set forth below, and are expressed as percentages of principal amount: REDEMPTION ---------- YEAR PRICE ---- ----- 2008..................................................................................... 103.375% 2009..................................................................................... 102.250% 2010..................................................................................... 101.125% 2011 and thereafter...................................................................... 100.000% In addition, at any time and from time to time, prior to July 1, 2006, the Issuer may redeem up to a maximum of 35% of the original aggregate principal amount of the Notes (calculated giving effect to any issuance of Additional Notes) with the proceeds of one or more Public Equity Offerings, at a redemption price equal to 106.750% of the principal amount thereof, plus accrued and unpaid interest to 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); provided, however, that after giving effect to any such redemption, at least 65% of the original aggregate principal amount of the Notes (calculated giving effect to any issuance of Additional Notes) remains outstanding (excluding Notes held by Arch Coal or any of its Subsidiaries). Any such redemption shall be made within 75 days of such Public Equity Offering upon not less than 30 nor more than 60 days' prior notice. 41 Any redemption pursuant to this Section 3.01 shall be made pursuant to the provisions of this Article Three. SECTION 3.02. Notices to Trustee. If the Issuer elects to redeem Notes pursuant to Section 3.01, it shall notify the Trustee in writing of the Redemption Date, the principal amount of Notes to be redeemed and the paragraph of the Notes pursuant to which the redemption will occur. The Issuer shall give each notice to the Trustee provided for in this Section 3.02 in writing at least 45 days before the date notice is mailed to the Holders pursuant to Section 3.04 unless the Trustee consents to a shorter period. Such notice shall be accompanied by an Officers' Certificate from the Issuer to the effect that such redemption will comply with the conditions herein. If fewer than all the Notes are to be redeemed, the Record Date relating to such redemption shall be selected by the Issuer and given to the Trustee, which Record Date shall be not less than 15 days after the date of notice to the Trustee. Except as otherwise provided herein, no notice or communication to the Trustee shall be deemed effectively given unless it is actually received by a Trust Officer at its Corporate Trust Office. SECTION 3.03. Selection of Notes to be Redeemed. If less than all of the Notes are to be redeemed, the Trustee shall select the Notes to be redeemed in compliance with the requirements, as certified to it by the Issuer, of the principal national securities exchange or automated quotation system, if any, on which the Notes are listed or, if the Notes are not listed on a national securities exchange or automated quotation system, by lot or by such other method as the Trustee in its sole discretion shall deem fair and appropriate; provided, however, that no such partial redemption shall reduce the portion of the principal amount of a Note not redeemed to less than $1,000. The Trustee shall make the selection from the Notes outstanding and not previously called for redemption. The Trustee may select for redemption portions equal to $1,000 in principal amount or any integral multiple thereof. Provisions of this Indenture that apply to Notes called for redemption also apply to portions of Notes called for redemption. The Trustee shall notify the Issuer and the Registrar promptly in writing of the Notes or portions of Notes to be called for redemption. SECTION 3.04. Notice of Redemption. (a) At least 30 days but not more than 60 days before a date for redemption of Notes, the Issuer shall mail a notice of redemption by first-class mail to each Holder to be redeemed and shall comply with the provisions of Section 13.02(b).

At the Issuer's written request, the Trustee shall give a notice of redemption in the Issuer's name and at the Issuer's expense. In such event, the Issuer shall provide the Trustee with the notice and the other information required by this Section 3.04. SECTION 3.05. Effect of Notice of Redemption. Once a notice of redemption is mailed, Notes called for redemption become due and payable on the Redemption Date and at the Redemption Price stated in the notice. Upon surrender of any Notes to the Paying Agent, such Notes shall be paid at the Redemption Price stated in the notice, plus accrued interest, if any, to the Redemption Date. In any event, failure to give such notice, or any defect therein, shall not effect the validity of the proceedings for the redemption of Notes held by Holders to whom such notice was properly given. Notice of redemption shall be deemed to be given when mailed, whether or not the Holder receives the notice. In any event, failure to give such notice, or any defect therein, shall not affect the validity of the proceedings for the redemption of Notes held by Holders to whom such notice was properly given. SECTION 3.06. Deposit of Redemption Price. On or prior to any Redemption Date, the Issuer shall deposit or cause to be deposited with the Paying Agent a sum in same day funds sufficient to pay the Redemption Price of and accrued interest on all Notes to be redeemed on that date other than Notes or portions of Notes called for redemption that have previously been delivered by the Issuer to the Trustee for cancellation. The Paying Agent shall return to the Issuer any money so deposited that is not required for that purpose. 43 SECTION 3.07. Payment of Notes Called for Redemption. If notice of redemption has been given in the manner provided above, the Notes or portion of Notes specified in such notice to be redeemed shall become due and payable on the Redemption Date at the Redemption Price stated therein, together with accrued interest to such Redemption Date, and on and after such date (unless the Issuer shall default in the payment of such Notes at the Redemption Price and accrued interest to the Redemption Date, in which case the principal, until paid, shall bear interest from the Redemption Date at the rate prescribed in the Notes), such Notes shall cease to accrue interest. Upon surrender of any Note for redemption in accordance with a notice of redemption, such Note shall be paid and redeemed by the Issuer at the Redemption Price, together with accrued interest, if any, to the Redemption Date; provided, however, that installments of interest whose Stated Maturity is on or prior to the Redemption Date shall be payable to the Holders registered as such at the close of business on the relevant Record Date. SECTION 3.08. Notes Redeemed in Part. (a) Upon surrender of a Global Note that is redeemed in part, the Paying Agent shall forward such Global Note to the Trustee who shall make a notation on the Security Register to reduce the principal amount of such Global Note to an amount equal to the unredeemed portion of the Global Note surrendered; provided, however, that each such Global Note shall be in a principal amount at final Stated Maturity of $1,000 or an integral multiple thereof. (b) Upon surrender and cancellation of a certificated Note that is redeemed in part, the Issuer shall execute and the Trustee shall authenticate for the Holder (at the Issuer's expense) a new Note equal in principal amount to the unredeemed portion of the Note surrendered and canceled; provided, however, that each such certificated Note shall be in a principal amount at final Stated Maturity of $1,000 or an integral multiple thereof. ARTICLE FOUR COVENANTS SECTION 4.01. Payment of Notes. Each of the Issuer and the Guarantors covenants and agrees for the benefit of the Holders that it shall duly and punctually pay the principal of, premium, if any, and interest on the Notes on the dates and in the manner provided in the Notes and in this Indenture. Principal, premium, if any, and interest shall be considered paid on the date due if on such date the Trustee or the Paying Agent (other than the Issuer or any of its Affiliates) holds, in accordance with this Indenture, money sufficient to pay all principal, premium, if any, and interest then due. If the Issuer or any of its Affiliates acts as Paying Agent, principal, premium, if any, and interest shall be considered paid on the due date if the entity acting as Paying Agent complies with Section 2.04. Each of the Issuer or the Guarantors shall pay interest on overdue principal at the rate specified therefor in the Notes. The Issuer or the Guarantors shall pay interest on overdue installments of interest at the same rate to the extent lawful. SECTION 4.02. Corporate Existence. Subject to Article Five, the Issuer and each Restricted Subsidiary shall do or cause to be done all things necessary to preserve and keep in full force and effect their corporate, partnership, limited liability company or other 44 existence and the rights (charter and statutory), licenses and franchises of Arch Western and each Restricted Subsidiary; provided, however, that Arch Western shall not be required to preserve any such right, licence or franchise if the Board of Directors of Arch Western shall determine that the preservation thereof is no longer desirable in the conduct of the business of the Issuer and the Restricted Subsidiaries as a whole and that the loss thereof is not disadvantageous in any material respect to the Holders. SECTION 4.03. Maintenance of Properties. Arch Western shall cause all properties owned by it or any of its Subsidiaries or used or held for use in the conduct of its business or the business of Arch Western or any of its Subsidiaries to be maintained and kept in good condition, repair and working order and supplied with all necessary equipment and shall cause to be made all necessary repairs, renewals, replacements, betterments and improvements thereof, all as, in the judgment of Arch Western, may be necessary so that the business carried on in connection therewith may be properly and advantageously conducted at all times; provided, however, that nothing in this Section 4.03 shall prevent Arch Western from discontinuing the maintenance of any such properties if such discontinuance is, in the judgment of Arch Western, desirable in the conduct of the business of Arch Western and its Subsidiaries as a whole and not disadvantageous in any material respect to the Holders. SECTION 4.04. Insurance. Arch Western shall maintain, and shall cause its Subsidiaries to maintain, insurance with carriers believed by Arch Western to be responsible, against such risks and in such amounts, and with such deductibles, retentions, self-insured amounts and coinsurance provisions, as Arch Western believes are customarily carried by businesses similarly situated and owning like properties, including as appropriate general liability, property and casualty loss and interruption of business insurance. SECTION 4.05. Statement as to Compliance. (a) The Issuer shall deliver to the Trustee, within 90 days after the end of each fiscal year, an Officers' Certificate stating that in the course of the performance by the signer of its duties as an officer of the Issuer he would normally have knowledge of any Default and whether or not the signer knows of any Default that occurred during such period and if any specifying such Default, its status and what action the Issuer is taking or proposed to take with respect thereto. For purposes of this Section 4.05(a), such compliance shall be determined without regard to any period of grace or requirement of notice under this Indenture. The Issuer shall comply with TIA Section 314(a)(4) The Issuer's delivery to the Trustee of the reports, information and documents required by said Section 314(a)(4) is for informational purposes only and the Trustee's receipt of such shall not constitute constructive notice of any information contained therein or determinable from information contained therein, including the Issuer's compliance with any of its covenants hereunder (as to which the Trustee is entitled to rely exclusively on Officers' Certificates).. (b) When any Default has occurred and is continuing under this Indenture, or if the trustee of, or the holder of, any other evidence of Debt of Arch Western or any Subsidiary outstanding in a principal amount of $25,000,000 or more gives any notice stating that it is a Notice of Default or takes any other action to accelerate such Debt or enforce any Note therefor, the Issuer shall deliver to the Trustee within five Business Days by registered or certified mail or 45 facsimile transmission an Officers' Certificate specifying such event, notice or other action, its status and what action the Issuer is taking or proposes to take with respect thereto. SECTION 4.06. Limitation on Debt. The Issuer shall not Incur any Debt other than the Notes and any Additional Notes. Arch Western shall not, and shall not permit any Restricted Subsidiary to, Incur, directly or indirectly, any Debt unless, after giving effect to the application of the proceeds thereof, no Default or Event of Default would occur as a consequence of such Incurrence or be continuing following such Incurrence and either: (1) such Debt is Debt of Arch Western or a Subsidiary Guarantor and, after giving effect to the Incurrence of such Debt and the application of the proceeds thereof, Consolidated Interest Coverage Ratio of Arch Western would be at least 2.0 to 1.0, or (2) such Debt is Permitted Debt. The term "Permitted Debt" is defined to include the following: (a) Debt of the Issuer evidenced by the Notes (not including any Additional Notes) issued in this offering and the Exchange Notes issued in exchange for such Notes and the Note Guarantees thereof; (b) Debt of Arch Western or a Restricted Subsidiary in respect of Capital Lease Obligations and Purchase Money Debt; provided that: (i) the aggregate principal amount of such Debt does not exceed the Fair Market Value (on the date of the Incurrence thereof) of the Property acquired, constructed or leased, and (ii) the aggregate principal amount of all Debt Incurred and then outstanding pursuant to this clause (b) (together with all Permitted Refinancing Debt Incurred and then outstanding in respect of Debt previously Incurred pursuant to this clause (b)) does not exceed, at any one time outstanding, 5% of Consolidated Net Tangible Assets; (c) Debt of Arch Western owing to and held by any Restricted Subsidiary and Debt of a Restricted Subsidiary owing to and held by Arch Western or any Restricted Subsidiary; provided, however, that (1) any subsequent issue or transfer of Capital Stock or other event that results in any such Restricted Subsidiary ceasing to be a Restricted Subsidiary or any subsequent transfer of any such Debt (except to Arch Western or a Restricted Subsidiary) shall be deemed, in each case, to constitute the Incurrence of such Debt by the issuer thereof and (2) if a Guarantor is the obligor on such Debt, such Debt is subordinated in right of payment to the Note Guarantee of such Guarantor; (d) Debt under Interest Rate Agreements entered into by Arch Western or a Restricted Subsidiary for the purpose of managing interest rate risk in the ordinary course of the financial management of Arch Western or such Restricted Subsidiary and not for speculative purposes, provided that the obligations under such agreements are directly related to payment obligations on Debt otherwise permitted by the terms of this covenant; 46 (e) Debt under Currency Exchange Protection Agreements entered into by Arch Western or a Restricted Subsidiary for the purpose of managing currency exchange rate risks directly related to transactions entered into by Arch Western or such Restricted Subsidiary in the ordinary course of business and not for speculative purposes; (f) Debt under Commodity Price Protection Agreements entered into by Arch Western or a Restricted Subsidiary in the ordinary course of the financial management of Arch Western or such Restricted Subsidiary and not for speculative purposes; (g) Debt in connection with one or more standby letters of credit or performance or surety bonds or completion guarantees issued by Arch Western or a Restricted Subsidiary in the ordinary course of business or pursuant to self-insurance obligations and not in connection with the borrowing of money or the obtaining of advances or credit; (h) Debt of Arch Western or a Restricted Subsidiary outstanding on the Issue Date not otherwise described in clauses (a) through (g) above; (i) other Debt of Arch Western or any Subsidiary Guarantor in an aggregate principal amount outstanding at any one time not to exceed $100,000,000; (j) Permitted Refinancing Debt Incurred in respect of Debt Incurred pursuant to clause (1) of the first paragraph of this Section 4.06 and clauses (b) and (h) above; and (k) Debt consisting of installment payment obligations to the federal government in connection with the acquisition of coal leases in the ordinary course of business and consistent with past practices. Notwithstanding anything to the contrary contained in this Section 4.06; (i) Arch Western shall not permit any Restricted Subsidiary that is not a Guarantor to Incur any Debt pursuant to this Section 4.06 if the proceeds thereof are used, directly or indirectly, to Refinance any Debt of any Guarantor; and (ii) accrual of interest, accretion or amortization of original issue discount and the payment of interest or dividends in the form of additional Debt, will be deemed not to be an Incurrence of Debt for purposes of this covenant. For purposes of determining compliance with this Section 4.06 in the event that an item of Debt meets the criteria of more than one of the categories of Permitted Debt described in clauses (a) through (j) above or is entitled to be incurred pursuant to clause (1) of the first paragraph of this Section 4.06, Arch Western shall, in its sole discretion, classify such item of Debt in any manner that complies with this Section 4.06. SECTION 4.07. Limitation on Liens. Arch Western shall not, and shall not permit any Restricted Subsidiary to, directly or indirectly, Incur or suffer to exist, any Lien on the Arch Coal Notes, except for the Liens securing the Notes and Additional Notes and Liens described in clause (k) of the definition of Permitted Liens. 47 Arch Western shall not, and shall not permit any Restricted Subsidiary to, directly or indirectly, Incur or suffer to exist, any Lien (other than Permitted Liens) upon any of its Property (including Capital Stock of a Restricted Subsidiary), whether owned at the Issue Date or thereafter acquired, or any interest therein or any income or profits therefrom, unless it has made or will make effective provision whereby the Notes or any Note Guarantee will be secured by such Lien equally and ratably with (or, if such other Debt constitutes Subordinated Obligations, prior to) all other Debt of Arch Western or any Restricted Subsidiary secured by such Lien for so long as such other Debt is secured by such Lien. SECTION 4.08. Limitation on Restricted Payments. Arch Western shall not make, and shall not permit any Restricted Subsidiary to make, directly or indirectly, any Restricted Payment if at the time of, and after giving effect to, such proposed Restricted Payment, (a) a Default or Event of Default shall have occurred and be continuing, (b) Arch Western could not Incur at least $1.00 of additional Debt pursuant to clause (1) of the first paragraph of Section 4.06 of this Indenture, (c) the aggregate amount of such Restricted Payment and all other Restricted Payments declared or made since the Issue Date (the amount of any Restricted Payment, if made other than in cash, to be based upon Fair Market Value at the time of such Restricted Payment) would exceed an amount equal to the sum of: (i) 50% of the aggregate amount of Consolidated Net Income of Arch Western accrued during the period (treated as one accounting period) from the beginning of the fiscal quarter during which the Issue Date occurs to the end of the most recent fiscal quarter ending at least 45 days prior to the date of such Restricted Payment (or if the aggregate amount of Consolidated Net Income of Arch Western for such period shall be a deficit, minus 100% of such deficit), plus (ii) 100% of the Capital Stock Sale Proceeds, plus (iii) the sum of: (1) the aggregate net cash proceeds received by Arch Western or any Restricted Subsidiary from the issuance or sale after the Issue Date of convertible or exchangeable Debt that has been converted into or exchanged for Capital Stock (other than Disqualified Stock) of Arch Western, and (2) the aggregate amount by which Debt (other than Subordinated Obligations) of Arch Western or any Restricted Subsidiary is reduced on Arch Western's consolidated balance sheet on or after the Issue Date upon the conversion or exchange of any Debt issued or sold on or prior to the Issue Date that is convertible or exchangeable for Capital Stock (other than Disqualified Stock) of Arch Western, excluding, in the case of clause (1) or (2): 48 (x) any such Debt issued or sold to Arch Western or a Subsidiary of Arch Western or an employee stock ownership plan or trust established by Arch Coal or any such Subsidiary for the benefit of their employees, and (y) the aggregate amount of any cash or other Property distributed by Arch Western or any Restricted Subsidiary upon any such conversion or exchange; plus (iv) an amount equal to the sum of: (B) the net reduction in Investments in any Person other than Arch Western or a Restricted Subsidiary resulting from dividends, repayments of loans or advances or other transfers of Property, in each case to Arch Western or any Restricted Subsidiary from such Person, and (C) the portion (proportionate to Arch Western's equity interest in such Unrestricted Subsidiary) of the Fair Market Value of the net assets of an Unrestricted Subsidiary of Arch Western at the time such Unrestricted Subsidiary is designated a Restricted Subsidiary; provided, however, that the foregoing sum shall not exceed, in the case of any Person, the amount of Investments previously made (and treated as a Restricted Payment) by Arch Western or any Restricted Subsidiary in such Person. Notwithstanding the foregoing limitation, Arch Western may: (a) pay dividends on its Capital Stock within 60 days of the declaration thereof if, on the declaration date, such dividends could have been paid in compliance with this Indenture; provided, however, that such dividend shall be included in the calculation of the amount of Restricted Payments; (b) purchase, repurchase, redeem, legally defease, acquire or retire for value Capital Stock of Arch Western or Subordinated Obligations in exchange for, or out of the proceeds of the substantially concurrent sale of, Capital Stock of Arch Western (other than Disqualified Stock and other than Capital Stock issued or sold to a Subsidiary of Arch Coal or an employee stock ownership plan or trust established by Arch Coal or any such Subsidiary for the benefit of their employees); provided, however, that (i) such purchase, repurchase, redemption, legal defeasance, acquisition or retirement shall be excluded in the calculation of the amount of Restricted Payments and (ii) the Capital Stock Sale Proceeds from such exchange or sale shall be excluded from the calculation pursuant to clause (c)(ii) above; 49 (c) purchase, repurchase, redeem, legally defease, acquire or retire for value any Subordinated Obligations in exchange for, or out of the proceeds of the substantially concurrent sale of, Permitted Refinancing Debt; provided, however, that such purchase, repurchase, redemption, legal defeasance, acquisition or retirement shall be excluded in the calculation of the amount of Restricted Payments; (d) repurchase shares of, or options to purchase shares of, common stock of Arch Western or any of its Subsidiaries from current or former officers, directors or employees of Arch Western or any of its Subsidiaries (or permitted transferees of such current or former officers, directors or employees), pursuant to the terms of agreements (including employment agreements) or plans (or amendments thereto) approved by the Board of Directors under which such individuals purchase or sell, or are granted the option to purchase or sell, shares of such common stock; provided, however, that: (1) the aggregate amount of such repurchases shall not exceed $2,500,000 in any calendar year and (2) at the time of such repurchase, no other Default or Event of Default shall have occurred and be continuing (or result therefrom); provided further, however, that such repurchases shall be included in the calculation of the amount of Restricted Payments; (e) so long as no Default or Event of Default has occurred and is continuing and Arch Western is a limited liability company, make distributions to the ARCO Member (as defined in the LLC Agreement), with respect to any period after March 31, 2003, not to exceed the Tax Amount allocated to such member under the LLC Agreement for such period; provided, however, that such distributions shall be included in the calculation of the amount of Restricted Payments; (f) so long as no Default or Event of Default has occurred and is continuing, make distributions of the Preferred Return (as defined in the LLC Agreement) to the ARCO Member (as defined in the LLC Agreement) pursuant to the LLC Agreement in effect on the Issue Date; provided, however, that such distribution shall be included in the calculation of the amount of Restricted Payments; and (g) so long as (i) no Default or Event of Default has occurred and is continuing and (ii) Arch Western could incur at least $1.00 of additional Debt pursuant to clause (l) of the first paragraph of Section 4.06 of this Indenture make loans or advances in cash to Arch Coal out of Available Cash as of the date of such loan or advance; provided, however, that such loans or advances shall be included in the calculation of the amount of Restricted Payments. Notwithstanding the prior two paragraphs, any Restricted Payment to, or Permitted Investments in, Arch Coal or any of its Affiliates (other than Arch Western or a Restricted Subsidiary) shall be in the form of a loan for cash which shall be evidenced by Arch Coal Notes that are immediately pledged to the Trustee on behalf of the Holders. SECTION 4.09. Limitation on Asset Sales. Arch Western shall not, and shall not permit any Restricted Subsidiary, to, directly or indirectly, sell, transfer or otherwise dispose of (including by means of a merger, consolidation or similar transaction) any shares of Capital Stock of the Issuer, Arch Western Notes or the Arch Coal Notes. Arch Western shall 50 not, and shall not permit any Restricted Subsidiary to, directly or indirectly, consummate any Asset Sale unless: (a) Arch Western or such Restricted Subsidiary receives consideration at the time of such Asset Sale at least equal to the Fair Market Value of the Property subject to such Asset Sale; (b) at least 75% of the consideration paid to Arch Western or such Restricted Subsidiary in connection with such Asset Sale is in the form of cash or Cash Equivalents or the assumption by the purchaser of liabilities of Arch Western or any Restricted Subsidiary (other than contingent liabilities or liabilities that are by their terms subordinated to the Notes) as a result of which Arch Western and the Restricted Subsidiaries are no longer obligated with respect to such liabilities; and (c) Arch Western delivers an Officers' Certificate to the Trustee certifying that such Asset Sale complies with the foregoing clauses (a) and (b). The Net Available Cash (or any portion thereof) from Asset Sales may be applied by Arch Western or a Restricted Subsidiary to the extent Arch Western or such Restricted Subsidiary elects (or is required by the terms of any Debt) to: (a) Repay any Debt of Arch Western or such Restricted Subsidiary (other than Subordinated Obligations); or (b) reinvest in Additional Assets (including by means of an Investment in Additional Assets by a Restricted Subsidiary with Net Available Cash received by Arch Western or another Restricted Subsidiary). Any Net Available Cash from an Asset Sale (other than an Asset Sale consisting of all of the Capital Stock of Canyon Fuel or Mountain Coal Company, L.L.C.) not applied in accordance with the preceding paragraph within 365 days from the date of the receipt of such Net Available Cash or that is not segregated from the general funds of Arch Western for investment in identified Additional Assets in respect of a project that shall have been commenced, and for which binding contractual commitments have been entered into, prior to the end of such 365-day period and that shall not have been completed or abandoned shall constitute "Excess Proceeds;" provided, however, that the amount of any Net Available Cash that ceases to be so segregated as contemplated above and any Net Available Cash that is segregated in respect of a project that is abandoned or completed shall also constitute "Excess Proceeds" at the time any such Net Available Cash ceases to be so segregated or at the time the relevant project is so abandoned or completed, as applicable; provided further, however, that the amount of any Net Available Cash that continues to be segregated for investment and that is not actually reinvested within twenty-four months from the date of the receipt of such Net Available Cash shall also constitute "Excess Proceeds." Any Net Available Cash from an Asset Sale consisting of all of the Capital Stock of Canyon Fuel or Mountain Coal Company, L.L.C. not applied in accordance with the preceding paragraph within 365 days from the date of the receipt of such Net Available Cash shall be segregated from the general funds of Arch Western and invested in cash or Cash Equivalents pending application in accordance with the preceding paragraph. 51 When the aggregate amount of Excess Proceeds (including income earned on such Excess Proceeds) exceeds $20,000,000, the Issuer will be required to make an offer to repurchase (the "Prepayment Offer") the Notes, which offer shall be in the amount of the Allocable Excess Proceeds (rounded to the nearest $1,000), on a pro rata basis according to principal amount, at a purchase price equal to 100% of the principal amount thereof, plus accrued and unpaid interest to the repurchase date (subject to the right of Holders of record on the relevant Record Date to receive interest due on the relevant interest payment date), in accordance with the procedures (including prorating in the event of oversubscription) set forth in this Indenture. To the extent that any portion of the amount of Net Available Cash remains after compliance with the preceding sentence and provided that all Holders of Notes have been given the opportunity to tender their Notes for repurchase in accordance with this Indenture, Arch Western or such Restricted Subsidiary may use such remaining amount for any purpose permitted by this Indenture, and the amount of Excess Proceeds will be reset to zero. The term "Allocable Excess Proceeds" shall mean the product of: (a) the Excess Proceeds and (b) a fraction, (i) the numerator of which is the aggregate principal amount of the Notes outstanding on the date of the Prepayment Offer, and (ii) the denominator of which is the sum of the aggregate principal amount of the Notes outstanding on the date of the Prepayment Offer and the aggregate principal amount of other Debt of Arch Western outstanding on the date of the Prepayment Offer that is pari passu in right of payment with the Arch Western Guarantee and subject to terms and conditions in respect of Asset Sales similar in all material respects to this covenant and requiring Arch Western to make an offer to repurchase such Debt at substantially the same time as the Prepayment Offer. Within five business days after the Issuer is obligated to make a Prepayment Offer as described in the preceding paragraph, the Issuer shall send a written notice, by first-class mail, to the Holders of Notes, accompanied by such information regarding Arch Western and its Subsidiaries as the Issuer in good faith believes will enable such Holders to make an informed decision with respect to such Prepayment Offer. Such notice shall state, among other things, the purchase price and the repurchase date, which shall be, subject to any contrary requirements of applicable law, a business day no earlier than 30 days nor later than 60 days from the date such notice is mailed. The Issuer will comply, to the extent applicable, with the requirements of Section 14(e) of the Exchange Act and any other securities laws or regulations in connection with the repurchase of Notes pursuant to this covenant. To the extent that the provisions of any securities laws or regulations conflict with provisions of this covenant, the Issuer will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under this covenant by virtue thereof. 52 SECTION 4.10. Limitation on Transactions with Affiliates. Arch Western shall not, and shall not permit any Restricted Subsidiary to, directly or indirectly, conduct any business or enter into or suffer to exist any transaction or series of transactions (including the purchase, sale, transfer, assignment, lease, conveyance or exchange of any Property or the rendering of any service) with, or for the benefit of, any Affiliate of Arch Western (an "Affiliate Transaction"), unless: (a) the terms of such Affiliate Transaction are: (1) set forth in writing, (2) in the best interest of Arch Western or such Restricted Subsidiary, as the case may be, and (3) no less favorable to Arch Western or such Restricted Subsidiary, as the case may be, than those that could be obtained in a comparable arm's-length transaction with a Person that is not an Affiliate of Arch Western, (b) if such Affiliate Transaction involves aggregate payments or value in excess of $5,000,000, the Board of Directors (including at least a majority of the disinterested members of the Board of Directors) approves such Affiliate Transaction and, in its good faith judgment, believes that such Affiliate Transaction complies with clauses (a)(2) and (3) of this paragraph as evidenced by a Board Resolution promptly delivered to the Trustee; provided, however, if there are no disinterested members of the Board of Directors, Arch Western shall receive a written opinion from an Independent Financial Advisor described in clause (c) below, and (c) if such Affiliate Transaction involves aggregate payments or value in excess of $25,000,000, Arch Western obtains a written opinion from an Independent Financial Advisor to the effect that the consideration to be paid or received in connection with such Affiliate Transaction is fair, from a financial point of view, to Arch Western and its Restricted Subsidiaries. Notwithstanding the foregoing limitation, Arch Western or any Restricted Subsidiary may enter into or suffer to exist the following: (a) any transaction or series of transactions between Arch Western and one or more Restricted Subsidiaries or between two or more Restricted Subsidiaries in the ordinary course of business, provided that no more than 5% of the total voting power of the Voting Stock (on a fully diluted basis) of any such Restricted Subsidiary is owned by an Affiliate of Arch Western (other than a Restricted Subsidiary); (b) any Restricted Payment (other than an Investment) permitted to be made pursuant to the first paragraph of Section 4.08 of this Indenture; (c) the payment of compensation (including amounts paid pursuant to employee benefit plans) for the personal services of officers, directors and employees of Arch Western or any of its Restricted Subsidiaries, so long as the Board of Directors in good faith shall have 53 approved the terms thereof and deemed the services theretofore or thereafter to be performed for such compensation to be fair consideration therefor; (d) loans and advances to employees made in the ordinary course of business permitted by law and consistent with the past practices of Arch Western or such Restricted Subsidiary, as the case may be, provided that such loans and advances do not exceed $2,500,000 in the aggregate at any one time outstanding; (e) agreements in effect on the Issue Date and described in the offering memorandum dated June 19, 2003, and any modifications, extensions or renewals thereto that are no less favorable to Arch Western or any Restricted Subsidiary than such agreements as in effect on the Issue Date; and (f) the Arch Coal Notes. SECTION 4.11. Change of Control. Upon the occurrence of a Change of Control, each holder of Notes shall have the right to require the Issuer to repurchase all or any part of such holder's Notes pursuant to the offer described below (the "Change of Control Offer") at a purchase price (the "Change of Control Purchase Price") equal to 101% of the principal amount thereof, plus accrued and unpaid interest to the repurchase date (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 repurchase date is after a Record Date and on or before the relevant interest payment date, the accrued and unpaid interest, if any, will be paid to the person or entity in whose name the Note is registered at the close of business on that Record Date, and no additional interest will be payable to Holders whose Notes shall be subject to redemption. Within 30 days following any Change of Control, the Issuer shall: (a) cause a notice of the Change of Control Offer to be sent at least once to the Dow Jones News Service or similar business news service in the United States; and (b) send, by first-class mail, with a copy to the Trustee, to each holder of Notes, at such holder's address appearing in the Security Register, a notice stating: (i) that a Change of Control has occurred and a Change of Control Offer is being made pursuant to this Section 4.11 of the Indenture and that all Notes timely tendered will be accepted for payment; (ii) the Change of Control Purchase Price and the repurchase date, which shall be, subject to any contrary requirements of applicable law, a business day no earlier than 30 days nor later than 60 days from the date such notice is mailed; (iii) the circumstances and relevant facts regarding the Change of Control (including information with respect to pro forma historical income, cash flow and capitalization after giving effect to the Change of Control); and 54 (iv) the procedures that Holders of Notes must follow in order to tender their Notes (or portions thereof) for payment, and the procedures that Holders of Notes must follow in order to withdraw an election to tender Notes (or portions thereof) for payment. The Issuer will not be required to make a Change of Control Offer following a Change of Control if a third party makes the Change of Control Offer in the manner, at the times and otherwise in compliance with the requirements set forth in this Indenture applicable to a Change of Control Offer made by the Issuer and purchases all Notes validly tendered and not withdrawn under such Change of Control Offer. The Issuer shall comply, to the extent applicable, with the requirements of Section 14(e) of the Exchange Act and any other securities laws or regulations in connection with the repurchase of Notes pursuant to a Change of Control Offer. To the extent that the provisions of any securities laws or regulations conflict with the provisions of this covenant, the Issuer will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under this covenant by virtue of such compliance. SECTION 4.12. Limitation on Sale and Leaseback Transactions. Arch Western shall not, and shall not permit any of its Restricted Subsidies to, enter into any Sale and Leaseback Transaction with respect to any Property unless: (a) Arch Western or such Restricted Subsidiary would be entitled to: (i) Incur Debt in an amount equal to the Attributable Debt with respect to such Sale and Leaseback Transaction pursuant to Section 4.06 of this Indenture and (ii) create a Lien on such Property securing such Attributable Debt without also securing the Notes or the applicable Note Guarantee pursuant to Section 4.07 of this Indenture and (b) such Sale and Leaseback Transaction is effected in compliance with Section 4.09 of this Indenture. SECTION 4.13. Guarantees by Restricted Subsidiaries. If the Company acquires or creates another Domestic Subsidiary after the Issue Date, then that newly acquired or created Subsidiary will become a Subsidiary Guarantor and execute a supplemental indenture within 10 days of the date on which it was created or acquired or became a Subsidiary; provided, however, that all Subsidiaries that have been properly designated as Unrestricted Subsidiaries in accordance with this Indenture for so long as they continue to constitute Unrestricted Subsidiaries will not have to become a Subsidiary Guarantor pursuant to this Section 4.13. In addition, Arch Western shall not permit any Restricted Subsidiary that is not a Guarantor, directly or indirectly, to Guarantee or secure the payment of any other Debt of Arch Western or any of its Restricted Subsidiaries unless such Restricted Subsidiary simultaneously executes and delivers a supplemental indenture to the Indenture providing for a Subsidiary Guarantee of the payment of the Notes by such Restricted Subsidiary; provided that this paragraph shall not be applicable to: 55 (i) any Guarantee of any Restricted Subsidiary that existed at the time such Person became a Restricted Subsidiary and was not incurred in connection with, or in contemplation of, such Person becoming a Restricted Subsidiary; (ii) any Guarantee arising under or in connection with performance bonds, indemnity bonds, surety bonds or letters of credit or bankers' acceptances; or (iii) Permitted Liens. If the Guaranteed Debt is a Subordinated Obligation, the Guarantee of such Guaranteed Debt must be subordinated in right of payment to the Subsidiary Guarantee to at least the extent that the Guaranteed Debt is subordinated to the Notes, or the applicable Subsidiary Guarantee. SECTION 4.14. Limitation on Restrictions on Distributions from Restricted Subsidiaries. Arch Western shall not, and shall not permit any Restricted Subsidiary to, directly or indirectly, create or otherwise cause or suffer to exist any consensual restriction on the right of any Restricted Subsidiary to: (a) pay dividends, in cash or otherwise, or make any other distributions on or in respect of its Capital Stock, or pay any Debt or other obligation owed, to Arch Western or any other Restricted Subsidiary, (b) make any loans or advances to Arch Western or any other Restricted Subsidiary, or (c) transfer any of its Property to Arch Western or any other Restricted Subsidiary. (d) The foregoing limitations will not apply: (i) with respect to clauses (a), (b) and (c), to restrictions: (1) in effect on the Issue Date (including, without limitation, restrictions pursuant to the Notes and the Indenture); (2) relating to Debt of a Restricted Subsidiary of Arch Western and existing at the time it became a Restricted Subsidiary if such restriction was not created in connection with or in anticipation of the transaction or series of transactions pursuant to which such Restricted Subsidiary became a Restricted Subsidiary or was acquired by Arch Western, or (3) that result from any amendment, restatement, renewal or replacement of an agreement referred to in clause (1)(A) or (B) above or in clause (2)(A) or (B) below, provided such restrictions are not less favorable, taken as a whole, to the Holders of Notes than those under the agreement evidencing the Debt so Refinanced, and (ii) with respect to clause (c) only, to restrictions: 56 (1) relating to Debt that is permitted to be Incurred and secured without also securing the Notes pursuant to Section 4.06 and 4.07 of this Indenture that limit the right of the debtor to dispose of the Property securing such Debt, (2) encumbering Property at the time such Property was acquired by Arch Western or any of its Restricted Subsidiaries, so long as such restrictions relate solely to the Property so acquired and were not created in connection with or in anticipation of such acquisition, (3) resulting from customary provisions restricting subletting or assignment of leases or customary provisions in other agreements that restrict assignment of such agreements or rights thereunder, or (4) customary restrictions contained in asset sale agreements limiting the transfer of such Property pending the closing of such sale. SECTION 4.15. Designation of Unrestricted and Restricted Subsidiaries. The Board of Directors of the Issuer may designate any Restricted Subsidiary (other than the Issuer) to be an Unrestricted Subsidiary if that designation (which would constitute an Investment in such Subsidiary) would not result in a breach of Section 4.08 of this Indenture or otherwise cause a Default. If a Restricted Subsidiary is designated as an Unrestricted Subsidiary, the aggregate Fair Market Value of all outstanding Investments owned by Arch Western and its Restricted Subsidiaries in the Subsidiary properly designated will be deemed to be an Investment made as of the time of the designation as set forth under the definition of "Investment" and will reduce the amount available for Restricted Payments under the first paragraph of Section 4.08 of this Indenture or Permitted Investments, as determined by Arch Western. That designation will only be permitted if the Investment would be permitted at that time and if the Restricted Subsidiary otherwise meets the definition of an Unrestricted Subsidiary. The Board of Directors may also designate any Subsidiary of Arch Western to be an Unrestricted Subsidiary if: (a) the Subsidiary to be so designated does not own any Capital Stock or Debt of, or own or hold any Lien on any Property of, Arch Western or any other Restricted Subsidiary and is not required to be a Guarantor pursuant to this Indenture, and (b) either: (i) the Subsidiary to be so designated has total assets of $1,000 or less, or (ii) such designation is effective immediately upon such entity becoming a Subsidiary of Arch Western. Unless so designated as an Unrestricted Subsidiary, any Person that becomes a Subsidiary of Arch Western will be classified as a Restricted Subsidiary; provided, however, that such Subsidiary shall not be designated a Restricted Subsidiary and shall be automatically classified as an Unrestricted Subsidiary if either of the requirements set forth in clauses (x) 57 and (y) of the second immediately following paragraph will not be satisfied after giving pro forma effect to such classification or if such Person is a Subsidiary of an Unrestricted Subsidiary. In addition, neither Arch Western nor any of its Restricted Subsidiaries shall at any time be directly or indirectly liable for any Debt that provides that the holder thereof may (with the passage of time or notice or both) declare a default thereon or cause the payment thereof to be accelerated or payable prior to its Stated Maturity upon the occurrence of a default with respect to any Debt, Lien or other obligation of any Unrestricted Subsidiary (including any right to take enforcement action against such Unrestricted Subsidiary). The Board of Directors may designate any Unrestricted Subsidiary to be a Restricted Subsidiary if, immediately after giving pro forma effect to such designation, (x) Arch Western could Incur at least $1.00 of additional Debt pursuant to clause (1) of the first paragraph of Section 4.06 of this Indenture and (y) no Default or Event of Default shall have occurred and be continuing or would result therefrom. Any such designation or redesignation by the Board of Directors will be evidenced by filing with the Trustee a Board Resolution giving effect to such designation or redesignation and an Officers' Certificate that: (a) certifies that such designation or redesignation complies with the foregoing provisions, and (b) gives the effective date of such designation or redesignation, such filing with the Trustee to occur within 45 days after the end of the fiscal quarter of Arch Western in which such designation or redesignation is made (or, in the case of a designation or redesignation made during the last fiscal quarter of Arch Western's fiscal year, within 90 days after the end of such fiscal year). SECTION 4.16. Payment of Taxes and Other Claims.

The Issuer shall also notify the Trustee within five Business Days of the occurrence of any Event of Default. SECTION 6.02. Acceleration. (a) If an Event of Default with respect to the Notes (other than an Event of Default specified in Section 6.01(a)(vii) or (viii) above) occurs and is continuing, then and in every such case the Trustee or the Holders of not less than 25% in aggregate principal amount of the Notes then outstanding by written notice to Arch Western or the Issuer (and to the Trustee if such notice is given by the Holders) may and the Trustee, upon the written request of such Holders shall, declare the principal amount of all of the outstanding Notes immediately due and payable, and upon any such declaration such principal amount in respect of the Notes shall become immediately due and payable. 64 (b) If an Event of Default specified in Section 6.01(a)(vii) or (viii) above occurs and is continuing, then the principal amount of all of the outstanding Notes shall ipso facto become and be immediately due and payable without any declaration or other act on the part of the Trustee or any Holder. (c) At any time after a declaration of acceleration under this Indenture, but before a judgment or decree for payment of the money due has been obtained by the Trustee, the Holders of a majority in aggregate principal amount of the outstanding Notes, by written notice to Arch Western or the Issuer and the Trustee, may waive all past Defaults and rescind and annul such declaration of acceleration and its consequences if: (i) The Issuer or the Guarantors have paid or deposited with the Trustee a sum sufficient to pay: (1) all overdue interest, if any, on all Notes then outstanding; (2) all unpaid principal of and premium, if any, on any outstanding Notes that has become due otherwise than by such declaration of acceleration and interest thereon at the rate borne by the Notes; (3) to the extent that payment of such interest is lawful, interest upon overdue interest, if any, at the rate borne by the Notes; and (4) all sums paid or advanced by the Trustee under this Indenture and the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel; (ii) the rescission would not conflict with any judgment or decree of a court of competent jurisdiction; and (iii) all Events of Default, other than the non-payment of amounts of principal of, premium, if any, and interest, if any, on the Notes that has become due solely by such declaration of acceleration, have been cured or waived as provided in Section 6.04. No such rescission shall affect any subsequent default or impair any right consequent thereon. (d) Notwithstanding Section 6.02(c) above, in the event of a declaration of acceleration in respect of the Notes because of an Event of Default specified in Section 6.01(a)(v) shall have occurred and be continuing, such declaration of acceleration shall be automatically annulled if the Indebtedness that is the subject of such Event of Default has been discharged or the Holders thereof have rescinded their declaration of acceleration in respect of such Indebtedness, and written notice of such discharge or rescission, as the case may be, shall have been given to the Trustee by the Issuer and countersigned by the Holders of such Indebtedness or a trustee, fiduciary or agent for such Holders, within 30 days after such declaration of acceleration in respect of the Notes, and no other Event of Default has occurred during such 30-day period which has not been cured or waived during such period. 65 (e) Subject to the Article Seven this Indenture relating to the duties of the Trustee, in case an Event of Default shall occur and be continuing, the Trustee will be under no obligation to exercise any of its rights or powers under this Indenture at the request or direction of any of the Holders, unless such Holders shall have offered to the Trustee reasonable indemnity. Subject to such provisions for the indemnification of the Trustee, the Holders of at least a majority in aggregate principal amount of the Notes then outstanding will have the right to 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 with respect to the Notes.

However, such limitations do not apply to a suit instituted by a holder of any Note for enforcement of payment of the principal of, and premium, if any, or interest on, such Note on or after the respective due dates expressed in such Note. SECTION 6.03. Other Remedies. If an Event of Default occurs and is continuing, the Trustee may in its discretion proceed to protect and enforce its rights and the rights of the Holders by such appropriate judicial proceedings as the Trustee shall deem most effectual to protect and enforce any such rights, whether for the specific enforcement of any covenant or agreement in this Indenture or in aid of the exercise of any power granted herein, or to enforce any other proper remedy. All rights of action and claims under this Indenture or the Notes may be prosecuted and enforced by the Trustee without the possession of any of the Notes or the production thereof in any proceeding relating thereto, and any such proceeding instituted by the Trustee shall be brought in its own name and as trustee of an express trust, and any recovery of judgment shall, after provision for the payment of the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, be for the ratable benefit of the Holders in respect of which such judgment has been recovered. SECTION 6.04. Waiver of Past Defaults. The Holders of not less than a majority in principal amount of the outstanding Notes may on behalf of the Holders of all the Notes waive any past Default hereunder and its consequences, except a Default: 66 (a) in respect of the payment of the principal of (or premium, if any), or interest on, any Note, or (b) in respect of a covenant or provision hereof which under Article Nine cannot be modified or amended without the consent of the Holder of each outstanding Note affected. 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 Event of Default or impair any right consequent thereon. SECTION 6.05. Control by Majority. The Holders of not less than a majority in aggregate principal amount of the Notes may direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or of exercising any trust or power conferred on the Trustee under this Indenture; provided that: (a) the Trustee may refuse to follow any direction that conflicts with law, this Indenture 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; (b) the Trustee may refuse to follow any direction that the Trustee determines is unduly prejudicial to the rights of other Holders or would involve the Trustee in personal liability; and (c) the Trustee may take any other action deemed proper by the Trustee that is not inconsistent with such direction. Prior to taking or not taking any action hereunder, the Trustee shall be entitled to indemnification satisfactory to it in its sole discretion against all losses and expenses caused by taking or not taking such action. SECTION 6.06. Limitation on Suits. A Holder may not pursue any remedy with respect to this Indenture or the Notes unless: (a) the Holder has previously given the Trustee written notice of a continuing Event of Default; (b) the Holders of at least 25% in aggregate principal amount of outstanding Notes shall have made a written request to the Trustee to pursue such remedy; (c) such Holder or Holders offer the Trustee indemnity reasonably satisfactory to the Trustee against any costs, liability or expense; (d) the Trustee does not comply with the request within 60 days after receipt of the request and the offer of indemnity; and 67 (e) during such 60-day period, the Holders of a majority in aggregate principal amount of the outstanding Notes do not give the Trustee a direction that is inconsistent with the request. The limitations in the foregoing provisions of this Section 6.06, however, do not apply to a suit instituted by a Holder for the enforcement of the payment of the principal of, premium, if any, or interest, if any, on such Note on or after the respective due dates expressed in such Note. A Holder may not use this Indenture to prejudice the rights of any other Holder or to obtain a preference or priority over another Holder. SECTION 6.07. Unconditional Right of Holders to Receive Payment. Notwithstanding any other provision of this Indenture, the right of any Holder to receive payment of principal of, premium, if any, and interest, if any, on the Notes held by such Holder, on or after the respective due dates expressed in the Notes, or to bring suit for the enforcement of any such payment on or after such respective dates, shall not be impaired or affected without the consent of such Holder. SECTION 6.08. Collection Suit by Trustee. The Issuer covenants that if default is made in the payment of: (a) any installment of interest on any Note when such interest becomes due and payable and such default continues for a period of 30 days, or (b) the principal of (or premium, if any, on) any Note at the Maturity thereof, the Issuer shall, upon demand of the Trustee, pay to the Trustee for the benefit of the Holders of such Notes, the whole amount then due and payable on such Notes for principal (and premium, if any), and interest, and interest on any overdue principal (and premium, if any) and, to the extent that payment of such interest shall be legally enforceable, upon any overdue installment of interest, at the rate borne by the Notes, and, in addition thereto, such further amount as shall be sufficient to cover the amounts provided for in Section 7.07 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. (c) If the Issuer fails to pay such amounts forthwith upon such demand, the Trustee, in its own name as trustee of an express trust, may institute a judicial proceeding for the collection of the sums so due and unpaid, may prosecute such proceeding to judgment or final decree and may enforce the same against the Issuer or any other obligor upon the Notes and collect the moneys adjudged or decreed to be payable in the manner provided by law out of the property of the Issuer or any other obligor upon the Notes, wherever situated. SECTION 6.09. Trustee May File Proofs of Claim. The Trustee may 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 any other amounts due the Trustee under Section 7.07) and the Holders allowed in any judicial proceedings relative to the Issuer or any Guarantor, their creditors or their property and, unless prohibited by law or 68 applicable regulations, may vote on behalf of the Holders at their direction in any election of a trustee in bankruptcy or other Person performing similar functions, and any Custodian in any such judicial proceeding is hereby authorized by each Holder to make 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 it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and its counsel, and any other amounts due the Trustee under Section 7.07. Nothing herein contained shall be deemed to empower the Trustee to authorize or consent to, or accept or adopt on behalf of any Holder, any plan of reorganization, arrangement, adjustment or composition affecting the Notes or the rights of any Holder thereof, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding. SECTION 6.10. Application of Money Collected. If the Trustee collects any money or other property (or the same is distributed) pursuant to this Article Six, it shall pay out the money or property in the following order: FIRST: to the Trustee (including any predecessor Trustee)for amounts due under Section 7.07; SECOND: to Holders for amounts due and unpaid on the Notes for principal of, 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 Issuer, any Guarantor or any other obligors of the Notes, as their interests may appear, or as a court of competent jurisdiction may direct. The Trustee may fix a Record Date and payment date for any payment to Holders pursuant to this Section 6.10. At least 15 days before such Record Date, the Issuer shall mail to each Holder and the Trustee a notice that states the Record Date, the payment date and amount to be paid. SECTION 6.11. Undertaking for Costs. A court may in its discretion require, 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 Trustee, the filing by any party litigant in the suit of an undertaking to pay the costs of such suit, and such court may in its discretion assess reasonable costs, including reasonable attorneys' fees, against any party litigant in such 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 Holders of more than 10% in aggregate principal amount of the outstanding Notes or to any suit by any Holder pursuant to Section 6.07. SECTION 6.12. Restoration of Rights and Remedies. If the Trustee or any Holder has instituted any proceeding to enforce any right or remedy under this Indenture and such proceeding has been discontinued or abandoned for any reason, or has been determined adversely to the Trustee or to such Holder, then and in every such case, subject to any determination in such proceeding, the Issuer, any Guarantor, the Trustee and the Holders shall be 69 restored severally and respectively to their former positions hereunder and thereafter all rights and remedies of the Trustee and the Holders shall continue as though no such proceeding had been instituted. SECTION 6.13. Rights and Remedies Cumulative. Except as otherwise provided with respect to the replacement or payment of mutilated, destroyed, lost or stolen Notes in Section 2.07, no right or remedy herein conferred upon or reserved to the Trustee or to the Holders is intended to be exclusive of any other right or remedy, and every right and remedy shall, to the extent permitted by law, be cumulative and in addition to every other right and remedy given hereunder or now or hereafter existing at law or in equity or otherwise. The assertion of any right or remedy hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other appropriate right or remedy. SECTION 6.14. Delay or Omission Not Waiver. No delay or omission of the Trustee or of any Holder of any Note to exercise any right or remedy accruing upon any Event of Default shall impair any such right or remedy or constitute a waiver of any such Event of Default or an acquiescence therein.

SECTION 6.16. Waiver of Stay or Extension Laws. The Issuer covenants (to the extent that it may lawfully do so) that it shall not at any time insist upon, or plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay or extension law wherever enacted, now or at any time hereafter in force, which may affect the covenants or the performance of this Indenture; and the Issuer (to the extent that it may lawfully do so) hereby expressly waives all benefit or advantage of any such law and covenants that it shall not hinder, delay or impede the execution of any power herein granted to the Trustee, but shall suffer and permit the execution of every such power as though no such law had been enacted.

(a) if an Event of Default has occurred and is continuing of which a Trust Officer of the Trustee has actual knowledge, the Trustee shall exercise such of the rights and powers vested in it by this Indenture, and use the same degree of care and skill in their exercise as a prudent person would exercise or use under the circumstances in the conduct of such person's own affairs; (b) except during the continuance of an Event of Default of which a Trust Officer of the Trustee has actual knowledge: (i) the Trustee undertakes to perform such duties and only 70 such duties as are specifically set forth in this Indenture and no others and no implied covenants or obligations shall be read into this Indenture against the Trustee; and (ii) in the absence of bad faith on its part, the Trustee may conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon certificates or opinions furnished to the Trustee and conforming to the requirements of this Indenture. In the case of any such certificates or opinions which by any provisions hereof are specifically required to be furnished to the Trustee, the Trustee shall examine same to determine whether they conform to the requirements of this Indenture (but need not confirm or investigate the accuracy of mathematical calculations or other facts stated therein); (c) the Trustee shall not be relieved from liability for its own negligent action, its own negligent failure to act or its own willful misconduct, except that: (i) this paragraph does not limit the effect of paragraph (b) of this Section 7.01; (ii) the Trustee shall not be liable for any error of judgment made in good faith by a Trust Officer unless it is proved that the Trustee was negligent in ascertaining the pertinent facts; and (iii) the Trustee shall not be liable with respect to any action it takes or omits to take in good faith in accordance with a direction received by it pursuant to Section 6.05; (d) the Trustee shall not be liable for interest on any money received by it except as the Trustee may agree in writing with the Issuer or any Guarantor. Money held in trust by the Trustee need not be segregated from other funds except to the extent required by law; (e) no provision of this Indenture shall require the Trustee to expend or risk its own funds or otherwise incur financial liability in the performance of any of its duties hereunder or in the exercise of any of its rights or powers, if it shall have reasonable grounds to believe that repayment of such funds or adequate indemnity against such risk or liability is not reasonably assured to it; and (f) whether or not therein expressly so provided, every provision of this Indenture relating to the conduct or affecting the liability of or affording protection to the Trustee shall be subject to the provisions of this Section 7.01 and to the provisions of the TIA. SECTION 7.02. Certain Rights of Trustee. (a) Subject to Section 7.01: (i) the Trustee may rely, and shall be protected in acting or refraining from acting, upon any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture, note, other evidence of indebtedness or other paper or document believed by it to be genuine and to have been signed or presented by the proper person; (ii) before the Trustee acts or refrains from acting, it may require an Officers' Certificate or an Opinion of Counsel, which shall conform to Section 13.05. The Trustee 71 shall not be liable for any action it takes or omits to take in good faith in reliance on such certificate or opinion; (iii) the Trustee may act through its attorneys and agents and shall not be responsible for the misconduct or negligence of any attorney or agent appointed with due care by it hereunder; (iv) the Trustee shall be under no obligation to exercise any of the rights or powers vested in it by this Indenture at the request or direction of any of the Holders, unless such Holders shall have offered to the Trustee reasonable security or indemnity against the costs, expenses and liabilities that might be incurred by it in compliance with such request or direction; (v) the Trustee shall not be liable for any action it takes or omits to take in good faith that it believes to be authorized or within its rights or powers, provided that the Trustee's conduct does not constitute negligence or bad faith; (vi) whenever in the administration of this Indenture the Trustee shall deem it desirable that a matter be proved or established prior to taking, suffering or omitting any action hereunder, the Trustee (unless other evidence be herein specifically prescribed) may, in the absence of bad faith on its part, rely upon an Officers' Certificate; and (vii) the Trustee shall not be bound to make any investigation into the facts or matters stated in any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture, note, other evidence of indebtedness or other paper or document, but the Trustee, in its discretion, may make such further inquiry or investigation into such facts or matters as it may see fit, and, if the Trustee shall determine to make such further inquiry or investigation, it shall be entitled to examine the books, records and premises of the Issuer personally or by agent or attorney. (viii) 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 (including its capacity under the Note Pledge Agreement), and each agent, custodian and other Person employed to act hereunder and under the Note Pledge Agreement; and the permissive right of the Trustee to take any action under this Indenture or under any other agreement in connection herewith shall not be construed as a duty; (ix) each Guarantor shall pay on demand to the Trustee any and all costs, fees and expenses (including without limitation, reasonable legal fees of counsel) incurred by the Trustee in enforcing any rights under any Guarantee; (x) the Trustee shall not be deemed to have notice of any Default or Event of Default unless a Trust Officer of the Trustee has actual knowledge thereof or unless written notice of any event which is in fact such a default is received by the Trustee at the Corporate Trust Office of the Trustee, and such notice references the Notes and this Indenture; 72 (xi) the permissive right of the Trustee to take any action under this Indenture or under any other agreement in connection herewith shall not be construed as a duty; (xii) unless otherwise specifically provided in this Indenture, any demand, request, direction or notice from the Issuer shall be sufficient if signed by an Officer of the Issuer; and (xiii) the trustee may consult with counsel and the advice of such counsel or any Opinion of Counsel shall 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. (b) The Trustee may request that the Issuer deliver an Officers' Certificate setting forth the names of the individuals and/or titles of officers authorized at such time to take specified actions pursuant to this Indenture, which Officers' Certificate may be signed by any person authorized to sign an Officers' Certificate, including any person specified as so authorized in any such certificate previously delivered and not superseded. SECTION 7.03. Individual Rights of Trustee. The Trustee, any Paying Agent, any Registrar or any other agent of the Issuer or of the Trustee, in its individual or any other capacity, may become the owner or pledgee of Notes and, subject to TIA Sections 310(b) and 311, may otherwise deal with the Issuer with the same rights it would have if it were not Trustee, Paying Agent, Registrar or such other agent. SECTION 7.04. Trustee's Disclaimer. The recitals contained herein and in the Notes, except for the Trustees certificates of authentication, shall be taken as the statements of the Issuer, and the Trustee assumes no responsibility for their correctness. The Trustee makes no representations as to the validity or sufficiency of this Indenture or of the Notes, except that the Trustee represents that it is duly authorized to execute and deliver this Indenture, authenticate the Notes and perform its obligations hereunder and agrees that the statements made by it in a Statement of Eligibility on Form T-1 supplied to the Issuer will be true and accurate, subject to the qualifications set forth therein. The Trustee shall not be accountable for the use or application by the Issuer of Notes or the proceeds thereof. It shall not be responsible for the use or application of any money received by any Paying Agent other than the Trustee, and it shall not be responsible for any statement or recital herein or any statement in the Notes or any other document in connection with the issuance or sale of the Notes or pursuant to this Indenture other than its certificate of authentication. Beyond the exercise of reasonable care in the custody thereof, the Trustee shall have no duty as to any Collateral in its possession or control or in the possession or control of any agent or bailee or any income thereon or as to preservation of rights against prior parties or any other rights pertaining thereto and the Trustee shall 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 security interest in the Collateral. The Trustee shall be deemed to have exercised reasonable care in the custody of the Collateral in its possession if the Collateral is accorded treatment substantially equal to that which it accords its own property and shall not be liable or responsible for any loss or diminution 73 in the value of any of the Collateral, by reason of the act or omission of any carrier, forwarding agency or other agent or bailee selected by the Trustee in good faith. The Trustee shall not be responsible for the existence, genuineness or value of any of the Collateral or for the validity, perfection, priority or enforceability of the Liens in any of the Collateral, whether impaired by operation of law or by reason of any action or omission to act on its part hereunder, except to the extent such action or omission constitutes gross negligence or willful misconduct on the part of the Trustee, for the validity or sufficiency of the Collateral or any agreement or assignment contained therein, for the validity of the title of the Company to the Collateral, for insuring the Collateral or for the payment of taxes, charges, assessments or Liens upon the Collateral or otherwise as to the maintenance of the Collateral. The Trustee shall have no duty to ascertain or inquire as to the performance or observance of any of the terms of this Indenture, the Collateral Agency Agreement or the Security Documents by the Issuer, any secured creditors or secured creditors' representatives, or the Collateral Trustee or any collateral agent. SECTION 7.05. Notice of Defaults. If any Default or any Event of Default occurs and is continuing and if such Default or Event of Default is known to the Trustee, the Trustee shall mail to each Holder in the manner and to the extent provided in TIA Section 313(c) notice of the Default or Event of Default within 45 days after it occurs, unless such Default or Event of Default has been cured; provided, however, that, except in the case of a default in the payment of the principal of, premium, if any, or interest on any Note, the Trustee shall be protected in withholding such notice if and so long as a committee of its Trust Officers in good faith determine that the withholding of such notice is in the interest of the Holders. The Trustee shall not be deemed to have knowledge of a Default unless a Trust Officer has actual knowledge of such Default or written notice of such Default has been received by the Trustee at its Corporate Trust Office in New York, New York, and such notice references the Notes and this Indenture SECTION 7.06. Reports by Trustee to Holders. Within 60 days after January 1 of each year commencing with the first January 1 after the Issue Date, the Trustee shall transmit to the Holders, in the manner and to the extent provided in TIA Section 313(c), a brief report dated as of such date that complies with TIA Section 313(a). The Trustee also shall comply with TIA Section 313(b) and (c). The Issuer shall promptly notify the Trustee whenever the Notes become listed on any securities exchange and of any delisting thereof and the Trustee shall comply with TIA Section 313(d). SECTION 7.07. Compensation and Indemnity. The Issuer, failing which each Guarantor, shall pay to the Trustee such compensation as shall be agreed in writing for its services hereunder. The Trustee's compensation shall not be limited by any law on compensation of a trustee of an express trust. The Issuer, failing which each Guarantor, shall reimburse the Trustee upon request for all reasonable out-of-pocket expenses incurred or made by it, including costs of collection, in addition to the compensation for its services. Such expenses shall include the reasonable compensation and out-of-pocket expenses of the Trustee's agents and counsel. 74 The Issuer, failing which each Guarantor, shall indemnify the Trustee (in any of its capacities in connection with any of the transactions contemplated hereby, including, without limitation, under this Indenture or under the Note Pledge Agreement) and its officers, directors, employees and agents for, and hold it and them harmless from and against any and all loss, liability or expense (including attorneys' fees and expenses) incurred by it or any of them without willful misconduct or negligence on its part arising out of or in connection with the administration of this trust and the performance of its duties hereunder (including the costs and expenses of enforcing this Indenture including this Section 7.07 and of defending itself against any claim, whether asserted by the Issuer, the Guarantors, any Holder or any other Person). The Trustee shall notify the Issuer promptly of any claim for which it may seek indemnity. Failure by the Trustee to so notify the Issuer shall not relieve the Issuer or the Guarantors of their obligations hereunder or under the Note Pledge Agreement. The Issuer shall defend the claim and the Trustee shall cooperate in such defense. The Trustee may have separate counsel and the Issuer shall pay the fees and expenses of such counsel. The Issuer need not pay for any settlement made without its consent, which consent may not be unreasonably withheld. The Issuer shall not reimburse any expense or indemnify against any loss, liability or expense incurred by the Trustee through the Trustee's own willful misconduct or negligence. To secure the Issuer's and each of the Guarantor's payment obligations in this Section 7.07, the Trustee shall have a Lien prior to the Notes upon the Collateral and on all money or property held or collected by the Trustee, hereunder or under the Note Pledge Agreement, in its capacity as Trustee, except money or property held in trust to pay principal of, premium, if any, and interest on particular Notes. When the Trustee incurs expenses after the occurrence of a Default specified in Section 6.01(a)(vii) or (viii) with respect to the Issuer, the Guarantors, or any Restricted Subsidiary, the expenses are intended to constitute expenses of administration under Bankruptcy Law. The Issuer's and each of the Guarantor's obligations under this Section 7.07, including the Lien and claim of the Trustee, and any claim arising hereunder shall survive the resignation or removal of any Trustee, the satisfaction and discharge of the Issuer's or Guarantor's obligations pursuant to Article Eight and any rejection or termination under any Bankruptcy Law, and the termination of this Indenture for any reason, and shall apply with equal force and effect to the Trustee in each of its capacities hereunder and each agent, custodian and other Person employed to act hereunder. "Trustee" for purposes of this Section 7.07 shall include any predecessor Trustee; provided, however, that the negligence or willful misconduct of any Trustee hereunder shall not affect the rights of any other Trustee hereunder. SECTION 7.08. Replacement of Trustee. A resignation or removal of the Trustee and appointment of a successor Trustee shall become effective only upon the successor Trustee's acceptance of appointment as provided in this Section 7.08. 75 The Trustee may resign at any time by so notifying the Issuer. The Holders of a majority in outstanding principal amount of the outstanding Notes may remove the Trustee by so notifying the Trustee and the Issuer. The Issuer shall remove the Trustee if: (a) the Trustee fails to comply with Section 7.10; (b) the Trustee is adjudged bankrupt or insolvent; (c) a receiver or other public officer takes charge of the Trustee or its property; or (d) the Trustee otherwise becomes incapable of acting. If the Trustee resigns or is removed, or if a vacancy exists in the office of Trustee for any reason, the Issuer shall promptly appoint a successor Trustee. Within one year after the successor Trustee takes office, the Holders of a majority in principal amount of the outstanding Notes may appoint a successor Trustee to replace the successor Trustee appointed by the Issuer. If the successor Trustee does not deliver its written acceptance required by the next succeeding paragraph of this Section 7.08 within 30 days after the retiring Trustee resigns or is removed, the retiring Trustee, the Issuer or the Holders of a majority in principal amount of the outstanding Notes may, at the expense of the Issuer, petition any court of competent jurisdiction for the appointment of a successor Trustee. A successor Trustee shall deliver a written acceptance of its appointment to the retiring Trustee and to the Issuer. Thereupon the resignation or removal of the retiring Trustee shall become effective, and the successor Trustee shall have all the rights, powers and duties of the Trustee under this Indenture. The successor Trustee shall mail a notice of its succession to Holders. The retiring Trustee shall promptly transfer all property held by it as Trustee to the successor Trustee. If a successor Trustee does not take office within 60 days after the retiring Trustee resigns or is removed, the retiring Trustee, the Issuer or the Holders of at least 25% in outstanding principal amount of the Notes may, at the Issuer's expense, petition any court of competent jurisdiction for the appointment of a successor Trustee at the expense of the Issuer. If the Trustee fails to comply with Section 7.10, any Holder may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee. The retiring Trustee shall promptly transfer all property held by it as Trustee to the successor Trustee, provided that all sums owing to the retiring Trustee hereunder have been paid and subject to the lien provided for in Section 7.07. Notwithstanding the replacement of the Trustee pursuant to this Section 7.08, the Issuer's and the Guarantors' obligations under Section 7.07 shall continue for the benefit of the retiring Trustee. SECTION 7.09. Successor Trustee by Merger. Any corporation into which the Trustee may be merged or converted or with which it may be consolidated, or any corporation resulting from any merger, conversion or consolidation to which the Trustee shall be a party, or any corporation succeeding to all or substantially all of the corporate trust business of the Trustee, shall be the successor of the Trustee hereunder, provided such corporation shall be 76 otherwise qualified and eligible under this Article Seven, without the execution or filing of any paper or any further act on the part of any of the parties hereto. In case any Notes shall have been authenticated, but not delivered, by the Trustee then in office, any successor by merger, conversion or consolidation to such authenticating Trustee may adopt such authentication and deliver the Notes so authenticated with the same effect as if such successor Trustee had itself authenticated such Notes. In case at that time any of the Notes shall not have been authenticated, any successor Trustee may authenticate such Notes either in the name of any predecessor hereunder or in the name of the successor Trustee. In all such cases such certificates shall have the full force and effect which this Indenture provides for the certificate of authentication of the Trustee shall have; provided, however, that the right to adopt the certificate of authentication of any predecessor Trustee or to authenticate Notes in the name of any predecessor Trustee shall apply only to its successor or successors by merger, conversion or consolidation. SECTION 7.10. Eligibility: Disqualification. The Trustee shall at all times satisfy the requirements of TIA Section 310(a)(1) and (5). The Trustee shall have a combined capital and surplus of at least $50,000,000 as set forth in its most recent published annual report of condition. No obligor upon the Notes or Person directly controlling, controlled by, or under common control with such obligor shall serve as trustee upon the Notes. The Trustee shall comply with TIA Section 310(b); provided, however, that there shall be excluded from the operation of TIA Section 310(b)(1) any indenture or indentures under which other securities or certificates of interest or participation in other notes of the Issuer are outstanding if the requirements for such exclusion set forth in TIA Section 310(b)(1) are met. For purposes of Section 310(b)(1) of the TIA and to the extent permitted thereby, the Trustee, in its capacity as trustee in respect of the Securities of any series, shall not be deemed to have a conflict of interest arising from its capacity as trustee in respect of the Securities of any other series. Nothing herein shall prevent the Trustee from filing with the Commission the application referred to in the second to last paragraph of Section 310(b) of the TIA. If the Trustee has or shall acquire a conflicting interest within the meaning of the TIA, the Trustee shall either eliminate such interest or resign, to the extent and in the manner provided by, and subject to the provisions of, the Trust Indenture Act and this Indenture.] SECTION 7.11. Preferential Collection of Claims Against Issuer. The Trustee shall comply with TIA Section 311(a), excluding any creditor relationship listed in TIA Section 311(b). A Trustee who has resigned or been removed shall be subject to TIA Section 311(a) to the extent indicated therein. SECTION 7.12. Appointment of Co-Trustee. (a) It is the purpose of this Indenture that there shall be no violation of any law of any jurisdiction denying or restricting the right of banking corporations or associations to transact business as trustee in such jurisdiction. It is recognized that in case of litigation under this Indenture or the Agreement, and in particular in case of the enforcement thereof on default, or in the case the Trustee deems that by reason of any present or future law of any jurisdiction it may not exercise any of the powers, rights or remedies herein granted to the Trustee or hold title to the properties, in trust, as herein granted or take any 77 action which may be desirable or necessary in connection therewith, it may be necessary that the Trustee appoint an individual or institution as a separate or co-trustee. The following provisions of this Section 7.12 are adopted to these ends. (b) In the event that the Trustee appoints an additional individual or institution as a separate or co-trustee, each and every remedy, power, right, claim, demand, cause of action, immunity, estate, title, interest and Lien expressed or intended by this Indenture to be exercised by or vested in or conveyed to the Trustee with respect thereto shall be exercisable by and vest in such separate or co-trustee but only to the extent necessary to enable such separate or co-trustee to exercise such powers, rights and remedies, and only to the extent that the Trustee by the laws of any jurisdiction is incapable of exercising such powers, rights and remedies, and every covenant and obligation necessary to the exercise thereof by such separate or co-trustee shall run to and be enforceable by either of them. (c) Should any instrument in writing from the Issuer be required by the separate or co-trustee so appointed by the Trustee for more fully and certainly vesting in and confirming to him or it such properties, rights, powers, trusts, duties and obligations, any and all such instruments in writing shall, on request, be executed, acknowledged and delivered by the Issuer; provided, however, that if an Event of Default shall have occurred and be continuing, if the Issuer does not execute any such instrument within 15 days after request therefor, the Trustees shall be empowered as an attorney-in-fact for the Issuer to execute any such instrument in the Issuer's name and stead. In case any separate or co-trustee or a successor to either shall die, become incapable or acting, resign or be removed, all the estates, properties, rights, powers, trusts, duties and obligations of such separate or co-trustee, so far as permitted by law, shall vest in and be exercised by the Trustee until the appointment of a new trustee or successor to such separate or co-trustee. (d) Each separate trustee and co-trustee shall, to the extent permitted by law, be appointed and act subject to the following provisions and conditions: (i) all rights and powers, conferred or imposed upon the Trustee shall be conferred or imposed upon and may be exercised or performed by such separate trustee or co-trustee; and (ii) no trustee hereunder shall be personally liable by reason of any act or omission of any other trustee hereunder. (e) Any notice, request or other writing given to the Trustee shall be deemed to have been given to each of the then separate trustees and co-trustees, as effectively as if given to each of them. Every instrument appointing any separate trustee or co-trustee shall refer to this Indenture and the conditions of this Article Seven. (f) Any separate trustee or co-trustee may at any time appoint the Trustee as its agent or attorney-in-fact with full power and authority, to the extent not prohibited by law, to do any lawful act under or in respect of this Indenture on its behalf and in its name. If any separate trustee or co-trustee shall die, become incapable of acting, resign or be removed, all of its estates, 78 properties, rights, remedies and trusts shall vest in and be exercised by the Trustee, to the extent permitted by law, without the appointment of a new or successors trustee. ARTICLE EIGHT DEFEASANCE; SATISFACTION AND DISCHARGE SECTION 8.01. Arch Western and the Issuer's Option to Effect Defeasance or Covenant Defeasance. Arch Western and the Issuer may, at their option by a resolution of the Boards of Directors, at any time, with respect to the Notes, elect to have either Section 8.02 or Section 8.03 be applied to all outstanding Notes upon compliance with the conditions set forth below in this Article Eight. SECTION 8.02. Defeasance and Discharge. Upon Arch Western's and the Issuer's exercise under Section 8.01 of the option applicable to this Section 8.02, Arch Western and the Issuer shall be deemed to have been discharged from its obligations with respect to the Notes on the date the conditions set forth in Section 8.04 are satisfied (hereinafter, "legal defeasance"). For this purpose, such legal defeasance means that Arch Western and the Issuer shall be deemed to have paid and discharged the entire indebtedness represented by the Notes and to have satisfied all its other obligations under the Notes and this Indenture (and the Trustee, at the expense of Arch Western and the Issuer, shall execute proper instruments acknowledging the same), except for the following which shall survive until otherwise terminated or discharged hereunder: (a) the rights of Holders of Notes to receive, solely from the trust fund described in Section 8.08 and as more fully set forth in such Section, payments in respect of the principal of (and premium, if any, on) and interest on such Notes when such payments are due, (b) the provisions set forth at Section 8.06 below and (c) the rights, powers, trusts, duties and immunities of the Trustee hereunder. Subject to compliance with this Article Eight, Arch Western and the Issuer may exercise its option under this Section 8.02 notwithstanding the prior exercise of its option under Section 8.03 below with respect to the Notes. If Arch Western and the Issuer exercise their legal defeasance option, payment of the Notes may not be accelerated because of an Event of Default. SECTION 8.03. Covenant Defeasance. Upon Arch Western's and the Issuer's exercise under Section 8.01 of the option applicable to this Section 8.03, Arch Western and the Issuer shall be released from their respective obligations under any covenant contained in Sections 4.04 through 4.15, 4.17 (other than the covenant to comply with TIA Section 314(a) to the extent that such obligations thereunder cannot be terminated), 5.01(b)(iv) and 6.01((iv),(v),(vi) and (vii) (only with respect to Significant Subsidiaries)) with respect to the Notes on and after the date the conditions set forth below are satisfied (hereinafter, "covenant defeasance"). For this purpose, such covenant defeasance means that, the Issuer may omit to comply with and shall have no liability in respect of any term, condition or limitation set forth in any such covenant, whether directly or indirectly, by reason of any reference elsewhere herein to any such covenant or by reason of any reference in any such covenant to any other provision herein or in any other document and such omission to comply shall not constitute a Default or an Event of Default, but, except as specified above, the remainder of this Indenture and such Notes shall be unaffected thereby. 79 SECTION 8.04. Conditions to Defeasance. The legal defeasance option or the covenant defeasance option may be exercised only if: (a) Arch Western or the Issuer irrevocably deposit in trust with the Trustee money or U.S. Government Obligations for the payment of principal of, premium, if any, and interest on the Notes to maturity or redemption, as the case may be; (b) Arch Western or the Issuer delivers to the Trustee a certificate from a nationally recognized firm of independent certified public accountants expressing their opinion that the payments of principal, premium, if any, and interest when due and without reinvestment on the deposited U.S. Government Obligations plus any deposited money without investment will provide cash at such times and in such amounts as will be sufficient to pay principal, premium, if any, and interest when due on all the Notes to be defeased to maturity or redemption, as the case may be; (c) 123 days pass after the deposit is made, and during the 123-day period, no Default described in Section 6.01(vii) and (viii) occurs with respect to Arch Western or the Issuer or any other Person making such deposit which is continuing at the end of the period; (d) no Default or Event of Default has occurred and is continuing on the date of such deposit and after giving effect thereto; (e) such deposit does not constitute a default under any other agreement or instrument binding on Arch Western or any of its Restricted Subsidiaries; (f) Arch Western or the Issuer delivers to the Trustee an Opinion of Counsel to the effect that the trust resulting from the deposit does not constitute, or is qualified as, a regulated investment company under the Investment Company Act of 1940; (g) in the case of the legal defeasance option, Arch Western or the Issuer delivers to the Trustee an Opinion of Counsel stating that: (i) Arch Western or the Issuer has received from the Internal Revenue Service a ruling, or (ii) since the date of this Indenture there has been a change in the applicable Federal income tax law, to the effect that, and based thereon such Opinion of Counsel shall confirm that, the Holders will not recognize income, gain or loss for Federal income tax purposes as a result of such defeasance and will be subject to Federal income tax on the same amounts, in the same manner and at the same time as would have been the case if such defeasance has not occurred; (h) in the case of the covenant defeasance option, Arch Western or the Issuer delivers to the Trustee an Opinion of Counsel to the effect that the Holders 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; and 80 (i) Arch Western or the Issuer delivers to the Trustee an Officers' Certificate and an Opinion of Counsel, each stating that all conditions precedent to the defeasance and discharge of the Notes have been complied with as required by this Article Eight. SECTION 8.05. Satisfaction and Discharge of Indenture. This Indenture shall be discharged and shall cease to be of further effect as to all Notes issued thereunder when either: (a) all such Notes previously authenticated and delivered (other than lost, stolen or destroyed Notes that have been replaced or paid and Notes for whose payment money or securities has theretofore been deposited in trust and thereafter repaid to the Issuer, as provided in Section 8.07) have been delivered to the Trustee for cancellation; or (b) (i) all such Notes not theretofore delivered to the Trustee for cancellation (A) have become due and payable by reason of the making of a notice of redemption or otherwise or (B) will become due and payable within one year, (ii) the Issuer has irrevocably deposited or caused to be deposited with the Trustee as trust funds in trust for such purpose an amount of U.S. Dollars or U.S. Government Obligations sufficient (in the opinion of a nationally recognized firm of independent public accountants expressed in a written certification thereof delivered to the Trustee), without consideration of any reinvestment of any interest thereon, to pay and discharge the entire indebtedness on such Notes not theretofore delivered to the Trustee for cancellation for principal, premium, if any, and accrued and unpaid interest, to the date of Stated Maturity or redemption, as the case may be and (iii) the Issuer has delivered an Officers' Certificate and an Opinion of Counsel to the Trustee stating that all conditions precedent to satisfaction and discharge have been complied with. SECTION 8.06. Survival of Certain Obligations. Notwithstanding Sections 8.01 and 8.03, any obligations of the Issuer and the Guarantors in Sections 2.02 through 2.14, 6.07, 7.07, 7.08, and 8.07 through 8.09 shall survive until the Notes have been paid in full. Thereafter, any obligations of the Issuer and the Guarantors in Sections 7.07, 8.07 and 8.08 shall survive such satisfaction and discharge. Nothing contained in this Article Eight shall abrogate any of the obligations or duties of the Trustee under this Indenture. SECTION 8.07. Acknowledgment of Discharge by Trustee. Subject to Section 8.09, after the conditions of Section 8.02 or 8.03 have been satisfied, the Trustee upon written request shall acknowledge in writing the discharge of all of the Issuer's obligations under this Indenture except for those surviving obligations specified in this Article Eight.

It shall apply the deposited cash or U.S. Dollars or U.S. Government Obligations through the Paying Agent and in accordance with this Indenture to the payment of principal of, premium, if any, interest, on the Notes; but such money need not be segregated from other funds except to the extent required by law.

The Trustee shall execute any documents reasonably requested by either Arch Western or a Subsidiary Guarantor in order to evidence the release of such Subsidiary Guarantor from its obligations under its Subsidiary Guarantee endorsed on the Notes and under this Article Ten. SECTION 10.04. Additional Guarantors.

SECTION 10.05. Limitation of Guarantee. The Guarantee is limited in an amount not to exceed the maximum amount that can be guaranteed by the Guarantor without rendering such Guarantee, as it relates to the Guarantor, voidable under applicable law relating to fraudulent conveyance or fraudulent transfer of similar laws affecting the rights of the creditors generally.

SECTION 10.08. No Waiver. Neither a failure nor a delay on the part of either the Trustee or the Holders in exercising any right, power or privilege under this Article Ten shall operate as a waiver thereof, nor shall a single or partial exercise thereof preclude any other or further exercise of any right, power or privilege. The rights, remedies and benefits of the Trustee and the Holders herein expressly specified are cumulative and are not exclusive of any other rights, remedies or benefits which either may have under this Article Ten at law, in equity, by statute or otherwise. SECTION 10.09. Modification. No modification, amendment or waiver of any provision of this Article Ten, nor the consent to any departure by the Guarantor therefrom, shall in any event be effective unless the same shall be in writing and signed by the Trustee, and then such waiver or consent shall be effective only in the specific instance and for the purpose for which given.

Arch Western shall take, and shall cause the Issuer and the Subsidiary Guarantors to take, any and all actions reasonably required to cause the Security Documents to create and maintain, as security for the obligations of the Issuer and the Guarantors hereunder, (x) a valid and 88 enforceable Lien on and security interest in all the Collateral in favor of the Trustee for the benefit of itself and of the Holders, and (y) such Lien as a perfected Lien.

The Trustee shall be deemed to have exercised reasonable care in the custody of the Collateral in its possession if the Collateral is accorded treatment substantially equal to that which it accords its own property and shall not be liable or responsible for any loss or diminution in the value of any of the Collateral by reason of the act or omission of any carrier, forwarding agency or other agent or bailee selected by the Trustee in good faith. The Trustee makes no representations as to and shall not be responsible for the existence, genuineness, value or condition of any of the Collateral or as to the security afforded or intended to be afforded thereby, hereby or by any security agreement, or for the validity, perfection, priority or enforceability of the Liens or security interests in any of the Collateral created or 90 intended to be created by any of the security agreements, whether impaired by operation of law or by reason of any action or omission to act on its part hereunder, except to the extent such action or omission constitutes gross negligence or willful misconduct on the part of the Trustee, for the validity or sufficiency of the Collateral, any security agreement or any agreement or assignment contained in any thereof, for the validity of the title of the Issuer or any of the Subsidiaries to the Collateral, for insuring the Collateral or for the payment of taxes, charges, assessments or Liens upon the Collateral or otherwise as to the maintenance of the Collateral.

Upon the cure of any Registration Deadline Event, Special Interest with respect to such event shall cease to accrue from the date of the filing, effectiveness or consummation that cured such event, as the case may be, if the Issuer and the Guarantors are otherwise in compliance with this paragraph.

Indenture The Issuer issued the Notes under an indenture dated as of June 25, 2003 (the "Indenture"), among the Issuer, the Guarantors and The Bank of New York, as trustee (the "Trustee"). The terms of the Notes include those stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act of 1939 as in effect on the date of the Indenture and, to the extent required by any amendment after such date, as so amended (the "Trust Indenture Act"). Terms defined in the Indenture and not defined herein have the meanings ascribed thereto in the Indenture. The Notes are subject to all such terms, and Holders are referred to the Indenture and the Trust Indenture Act for a statement of those terms. The Notes are unsecured senior guaranteed obligations of the Issuer and are issued in an initial aggregate principal amount $700,000,000.

Starting on that date, the Issuer may redeem all or any portion of the Notes, at once or over time, after giving the required notice under this Indenture at the A-6 redemption prices set forth below, plus accrued and unpaid interest to 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). The following prices are for Notes redeemed during the 12-month period commencing on July 1, 2008 of the years set forth below, and are expressed as percentages of principal amount: REDEMPTION YEAR PRICE ---- ----- 2008................................ 103.375% 2009................................ 102.250% 2010................................ 101.125% 2011 and thereafter................. 100.000% In addition, at any time and from time to time, prior to July 1, 2006, the Issuer may redeem up to a maximum of 35% of the original aggregate principal amount of the Notes (calculated giving effect to any issuance of Additional Notes) with the proceeds of one or more Public Equity Offerings, at a redemption price equal to 106.750% of the principal amount thereof, plus accrued and unpaid interest to 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); provided, however, that after giving effect to any such redemption, at least 65% of the original aggregate principal amount of the Notes (calculated giving effect to any issuance of Additional Notes) remains outstanding (excluding Notes held by Arch Coal or any of its Subsidiaries). Any such redemption shall be made within 75 days of such Public Equity Offering upon not less than 30 nor more than 60 days' prior notice. Any redemption pursuant to this Section 3.01 shall be made pursuant to the provisions of this Article Three. 7. Notice of Redemption Notice of redemption will be mailed first-class postage prepaid at least 30 days but not more than 60 days before the Redemption Date to the Holder of this Note to be redeemed at the addresses contained in the Security Register.

In the event of a redemption of less than all of the Notes, the Notes for redemption will be chosen by the Trustee in accordance with the Indenture. If this Note is redeemed subsequent to a Record Date with respect to any Interest Payment Date specified above, then any accrued interest will be paid to the Holder at the close of business on such Record Date. If money sufficient to pay the Redemption Price of and accrued interest on all Notes (or portions thereof) to be redeemed on the Redemption Date is deposited with the applicable Paying Agent on or before the Redemption Date and certain other conditions are satisfied, interest ceases to accrue on such Notes (or such portions thereof) called for redemption on or after such date. 8. Repurchase at the Option of Holders Upon the occurrence of a Change of Control, each holder of Notes shall have the right to require the Issuer to repurchase all or any part of such holder's Notes pursuant to the offer A-7 described below (the "Change of Control Offer") at a purchase price (the "Change of Control Purchase Price") equal to 101% of the principal amount thereof, plus accrued and unpaid interest to the repurchase date (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 repurchase date is after a Record Date and on or before the relevant interest payment date, the accrued and unpaid interest, if any, will be paid to the person or entity in whose name the Note is registered at the close of business on that Record Date, and no additional interest will be payable to holders whose Notes shall be subject to redemption. Within 30 days following any Change of Control, the Issuer shall: (a) cause a notice of the Change of Control Offer to be sent at least once to the Dow Jones News Service or similar business news service in the United States; and (b) send, by first-class mail, with a copy to the Trustee, to each holder of Notes, at such holder's address appearing in the Security Register, a notice stating: (1) that a Change of Control has occurred and a Change of Control Offer is being made pursuant to Section 4.11 of the Indenture and that all Notes timely tendered will be accepted for payment; (2) the Change of Control Purchase Price and the repurchase date, which shall be, subject to any contrary requirements of applicable law, a business day no earlier than 30 days nor later than 60 days from the date such notice is mailed; (3) the circumstances and relevant facts regarding the Change of Control (including information with respect to pro forma historical income, cash flow and capitalization after giving effect to the Change of Control); and (4) the procedures that holders of Notes must follow in order to tender their Notes (or portions thereof) for payment, and the procedures that holders of Notes must follow in order to withdraw an election to tender Notes (or portions thereof) for payment. The Issuer will not be required to make a Change of Control Offer following a Change of Control if a third party makes the Change of Control Offer in the manner, at the times and otherwise in compliance with the requirements set forth in the Indenture applicable to a Change of Control Offer made by the Issuer and purchases all Notes validly tendered and not withdrawn under such Change of Control Offer. The Issuer shall comply, to the extent applicable, with the requirements of Section 14(e) of the Exchange Act and any other securities laws or regulations in connection with the repurchase of Notes pursuant to a Change of Control Offer. To the extent that the provisions of any securities laws or regulations conflict with the provisions of this covenant, the Issuer will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under this covenant by virtue of such compliance. A-8 9. Denominations The Notes are in denominations of $1,000 and integral multiples of $1,000 of principal amount.

Unclaimed Money All moneys paid by the Issuer or the Guarantors to the Trustee or a Paying Agent for the payment of the principal of, or premium, if any, or interest on, any Notes that remain unclaimed at the end of three years after such principal, premium or interest has become due and payable may be repaid to the Issuer or the Guarantors, subject to applicable law, and the Holder of such Note thereafter may look only to the Issuer or the Guarantors for payment thereof. 11. Discharge and Defeasance Subject to certain conditions, the Issuer at any time may terminate some or all of its obligations and the obligations of the Guarantors under the Notes, the Guarantees and the Indenture if the Issuer irrevocably deposits with the Trustee U.S. Dollars or U.S. Government Obligations for the payment of principal and interest on the Notes to redemption or maturity, as the case may be. 12. Amendment, Supplement and Waiver Subject to certain exceptions set forth in the Indenture, the Indenture may be amended or supplemented with the written consent of the Holders of at least a majority in aggregate principal amount of the relevant Notes then outstanding (including consents obtained in connection with a tender offer or exchange offer for the Notes) and any existing default or compliance with any provisions may be waived with the consent of the Holders of at least a majority in aggregate principal amount of the Notes then outstanding. However, without the consent of the Holder of each outstanding Note affected thereby, an amendment may not: (a) reduce the amount of Notes whose Holders must consent to an amendment or waiver, (b) reduce the rate of, or extend the time for payment of, interest on any Note, (c) reduce the principal of, or extend the Stated Maturity of, any Note, (d) make any Note payable in money other than that stated in the Note, (e) impair the right of any Holder to receive payment of principal of, premium, if any, and interest, on, such holder's Notes on or after the due dates therefor or to institute suit for the enforcement of any payment on or with respect to such Holder's Notes, A-9 (f) release any security interest that may have been granted in favor of the Holders other than pursuant to the terms of such security interest, (g) reduce the premium payable upon the redemption of any Note or change the time at which any Note may be redeemed, pursuant to Section 3.01 of the Indenture (h) reduce the premium payable upon a Change of Control or, at any time after a Change of Control has occurred, change the time at which the Change of Control Offer relating thereto must be made or at which the Notes must be repurchased pursuant to such Change of Control Offer, (i) at any time after the Issuer is obligated to make a Prepayment Offer with the Excess Proceeds from Asset Sales, change the time at which such Prepayment Offer must be made or at which the Notes must be repurchased pursuant thereto, (j) modify or change any provision of the Indenture affecting the ranking of the Notes or the Note Guarantees in a manner adverse to the Holders (it being understood that amendments or waivers of Security Documents or releases of Liens on the Arch Coal Notes do not relate to ranking), or (k) release any Guarantor from any of its obligations under its Note Guarantee or the Indenture other than in accordance with the provisions of the Indenture, or amend or modify any provision relating to such release. The consent of the Holders is not necessary under the Indenture to approve the particular form of any proposed amendment. It is sufficient if such consent approves the substance of the proposed amendment. Notwithstanding the foregoing, without notice to or the consent of any Holder of the Notes, the Issuer, the Guarantors and the Trustee may, among other things, modify, amend or supplement the Indenture: (a) cure any ambiguity, omission, defect or inconsistency in any manner that is not adverse in any material respect to any holder of the Notes, (b) provide for the assumption by a Surviving Person of the obligations of Arch Western under the Indenture, (c) provide for uncertificated Notes in addition to or in place of certificated Notes (provided that the uncertificated Notes are issued in registered form for purposes of Section 163(f) of the Code, or in a manner such that the uncertificated Notes are described in Section 163(f)(2)(B) of the Code), (d) add Note Guarantees with respect to the Notes or confirm and evidence the release, termination or discharge of any security or Note Guarantee when such release, termination or discharge is permitted by the Indenture, A-10 (e) secure the Notes, add to the covenants of the Issuer for the benefit of the Holders or surrender any right or power conferred upon the Issuer, (f) make any change that does not adversely affect the rights of any holder of the Notes, (g) comply with any requirement of the Commission in connection with the qualification of this Indenture under the Trust Indenture Act, or (h) provide for the issuance of Additional Notes in accordance with the Indenture. After an amendment becomes effective in accordance with the above position, the Issuer shall mail to each Holder at such Holder's address appearing in the Security Register a notice briefly describing such amendment. However, the failure to give such notice to all Holders, or any defect therein, will not impair or affect the validity of the amendment. 13. Defaults and Remedies The Notes have the Events of Default as set forth in Section 6.01 of the Indenture. If an Event of Default occurs and is continuing, the Trustee, by notice to the Issuer, or the registered Holders of not less than 25% in aggregate principal amount of the Notes then outstanding by notice to the Issuer and the Trustee, subject to certain limitations, may declare all the Notes to be due and payable immediately. Certain events of bankruptcy or insolvency are Events of Default and shall result in the Notes being due and payable immediately upon the occurrence of such Events of Default. Holders may not enforce the Indenture or the Notes except as provided in the Indenture. The Trustee may refuse to enforce the Indenture or the Notes unless it receives an indemnity satisfactory to it. Subject to certain limitations, Holders of a majority in aggregate principal amount of the Notes may direct the Trustee in its exercise of any trust or power. The Holders of a majority in aggregate principal amount of the Notes then outstanding by written notice to the Trustee may rescind any acceleration and its consequence if the rescission would not conflict with any judgment or decree and if all existing Events of Default have been cured or waived except nonpayment of principal, premium, if any, or interest that has become due solely because of such acceleration. The above description of Events of Default and remedies is qualified by reference, and subject in its entirety, to the more complete description thereof contained in the Indenture. 14. Trustee Dealings with the Issuer Subject to certain limitations imposed by the Trust Indenture Act, the Trustee under the Indenture, in its individual or any other capacity, may become the owner or pledgee of Notes and may otherwise deal with and collect obligations owed to it by the Issuer, the Guarantor or any of their Affiliates with the same rights it would have if it were not Trustee. Any Paying Agent, Registrar, co-Registrar or co-Paying Agent may do the same with like rights. 15. No Recourse Against Others A-11 A director, officer, employee, or stockholder, as such, of the Issuer or the Guarantor shall not have any liability for any obligations of the Issuer or the Guarantor under the Notes, the Guarantees or the Indenture or for any claim based on, in respect of, or by reason of, such obligations or their creation. By accepting a Note, each Holder shall waive and release all such liability. The waiver and release are part of the consideration for the issue of the Notes. 16. Authentication This Note shall not be valid until an authorized officer of the Trustee (or an authenticating agent) manually signs the certificate of authentication on the other side of this Note. 17.
