(f) At the Execution Time and at the Closing Date, the Company shall have requested and caused Ernst & Young LLP to furnish to the Representatives letters, dated respectively as of the Execution Time and as of the Closing Date, in form and substance satisfactory to the Representatives, confirming that they are independent accountants within the meaning of the Act and the Exchange Act, that they have performed a review of the unaudited 23 interim consolidated financial information of Canyon Fuel for the three-month period ended March 31, 2003 and as at March 31, 2003, and stating in effect that: (i) in their opinion the audited financial statements of Canyon Fuel included in the Final Memorandum and reported on by them comply in form in all material respects with the applicable accounting requirements of the Exchange Act; (ii) on the basis of a reading of the latest unaudited consolidated financial statements made available by Canyon Fuel their limited review in accordance with the standards established under Statement on Auditing Standards No. 100, of the unaudited interim financial information for the three-month period ended March 31, 2003 and as at March 31, 2003; carrying out certain specified procedures (but not an examination in accordance with generally accepted auditing standards) which would not necessarily reveal matters of significance with respect to the comments set forth in such letter; a reading of the minutes of the meetings of the directors; and inquiries of certain officials of Canyon Fuel who have responsibility for financial and accounting matters of Canyon Fuel and its subsidiaries, as to transactions and events subsequent to December 31, 2002, nothing came to their attention which caused them to believe that: (1) any unaudited financial statements included in the Final Memorandum do not comply in form in all material respects with applicable accounting requirements and with the published rules and regulations of the Commission with respect to financial statements included or incorporated in quarterly reports on Form 10-Q under the Exchange Act; and said unaudited financial statements are not in conformity with generally accepted accounting principles applied on a basis substantially consistent with that of the audited financial statements included in the Final Memorandum; or (2) with respect to the period subsequent to March 31, 2003, there were any changes, at a specified date not more than five days prior to the date of the letter, in the long-term debt of Canyon Fuel or decreases in the members' equity of the Canyon Fuel or net current assets of the Canyon Fuel as compared with the amounts shown on the March 31, 2003 consolidated balance sheet included in the Final Memorandum, or for the period from April 1, 2003 to such specified date there were any decreases, as compared with the corresponding period in the preceding year in net revenue, income before extraordinary items or in net income of Canyon Fuel and its subsidiaries; or (iii) they have performed certain other specified procedures as a result of which they determined that certain information of an accounting, financial or statistical nature (which is limited to accounting, financial or statistical information derived from the general accounting records of the Canyon Fuel and its subsidiaries) set forth in the Final Memorandum in the Final Memorandum, agrees with the accounting records of the Canyon Fuel and its subsidiaries, excluding any questions of legal interpretation.

References to the Final Memorandum in this Section 6(g) include any amendment or supplement thereto at the date of the applicable letter. (h) Subsequent to the Execution Time or, if earlier, the dates as of which information is given in the Final Memorandum (exclusive of any amendment or supplement thereto), there shall not have been (i) any change or decrease specified in the letter or letters referred to in paragraphs (e), (f) and (g) of this Section 6; or (ii) any change, or any development involving a prospective change, in or affecting the condition (financial or otherwise), prospects, earnings, business or properties of (i) the Company and its subsidiaries, taken as a whole, or (ii) Arch Western and its subsidiaries, taken as a whole, whether or not arising from transactions in the ordinary course of business, except as set forth in or contemplated in the Final Memorandum (exclusive of any amendment or supplement thereto) the effect of which, in any case referred to in clause (i) or (ii) above, is, in the sole judgment of the Representatives, so material and adverse as to make it impractical or inadvisable to proceed with the offering, sale or delivery of the Securities as contemplated by the Final Memorandum (exclusive of any amendment or supplement thereto). (i) The Securities shall have been designated as PORTAL-eligible securities in accordance with the rules and regulations of the NASD, and the Securities shall be eligible for clearance and settlement through The Depository Trust Company.

(k) Prior to the Closing Date, the Company shall have furnished to the Representatives an executed copy of an Agreement of Members of Arch Western pursuant to which Delta Housing Inc. and Arch Western Acquisition Corporation agreed that the consummation of the transactions contemplated by this Agreement, the Indenture, the Registration Rights Agreement, the Pledge Agreement and the Final Memorandum are permitted under the Limited Liability Company Agreement of Arch Western. (l) Prior to the Closing Date, the Company shall have received from PNC Bank, on behalf of the lenders party under the $350,000,000 Amended and Restated Revolving Credit Facility , dated as of April 18, 2002, by and among the Company and the lenders party thereto (the "Company Credit Facility"), (i) an irrevocable waiver of any Event of Default (as defined in, and under, the Company Credit Facility) caused, directly or indirectly, by the transactions contemplated by this Agreement, the Indenture, the Registration Rights Agreements, the Pledge Agreement and the Final Memorandum and (ii) an irrevocable consent to the consummation of such transactions; and such waiver and consent, a copy of which shall have been furnished to the Representatives prior to the Closing Date, shall be in full force and effect on the Closing Date. 26 (m) Prior to the Closing Date, the Issuer, the Company and the Guarantors shall have furnished to the Representatives such further consents, waivers, information, certificates and documents as the Representatives may reasonably request. If any of the conditions specified in this Section 6 shall not have been fulfilled in all material respects when and as provided in this Agreement, or if any of the opinions and certificates mentioned above or elsewhere in this Agreement shall not be in all material respects reasonably satisfactory in form and substance to the Representatives and counsel for the Initial Purchasers, this Agreement and all obligations of the Initial Purchasers hereunder may be canceled at, or at any time prior to, the Closing Date by the Representatives. Notice of such cancellation shall be given to the Company in writing or by telephone or facsimile confirmed in writing. The documents required to be delivered by this Section 6 will be delivered at the office of counsel for the Initial Purchasers, at Shearman & Sterling LLP, 599 Lexington Avenue, New York, New York 10022-6069, on the Closing Date. 7. Reimbursement of Expenses. If the sale of the Securities provided for herein is not consummated because any condition to the obligations of the Initial Purchasers set forth in Section 6 hereof is not satisfied, because of any termination pursuant to Section 10 hereof or because of any refusal, inability or failure on the part of the Issuer, the Company or any Guarantor to perform any agreement herein or comply with any provision hereof other than by reason of a default by any of the Initial Purchasers, each of the Issuer, the Company and the Guarantors, jointly and severally, agrees that it will reimburse the Initial Purchasers severally through Citigroup Global Markets Inc. on demand for all out-of-pocket expenses (including reasonable fees and disbursements of counsel) that shall have been incurred by them in connection with the proposed purchase and sale of the Securities. 8. Indemnification and Contribution. (a) Each of the Issuer, the Company and the Guarantors, jointly and severally, agrees to indemnify and hold harmless each Initial Purchaser, the affiliates, directors, officers, employees and agents of each Initial Purchaser and each person who controls any Initial Purchaser within the meaning of either the Act or the Exchange Act against any and all losses, claims, damages or liabilities, joint or several, to which they or any of them may become subject under the Act, the Exchange Act or other Federal or state statutory law or regulation, at common law or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of a material fact contained in the Preliminary Memorandum, the Final Memorandum (or in any supplement or amendment thereto) or any information provided by the Issuer or any Guarantor to any holder or prospective purchaser of Securities pursuant to Section 5(h), or in any amendment thereof or received by it supplement thereto, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, and agrees to reimburse each such indemnified party, as incurred, for any legal or other expenses reasonably incurred by them in connection with investigating or defending any such loss, claim, damage, liability or action; provided, however, that neither the Issuer, nor the Company nor any Guarantor will be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based 27 upon any such untrue statement or alleged untrue statement or omission or alleged omission made in the Preliminary Memorandum or the Final Memorandum, or in any amendment thereof or supplement thereto, in reliance upon and in conformity with written information furnished to the Issuer, the Company or any Guarantor by or on behalf of any Initial Purchasers through the Representatives specifically for inclusion therein. This indemnity agreement will be in addition to any liability which the Issuer, the Company or any Guarantor may otherwise have. (b) Each Initial Purchaser severally and not jointly agrees to indemnify and hold harmless the Issuer, the Company and the Guarantors, each of their respective directors, each of their respective officers, and each person who controls the Issuer, the Company or any Guarantor within the meaning of either the Act or the Exchange Act, to the same extent as the foregoing indemnity from each of the Issuer, the Company and the Guarantors to each Initial Purchaser, but only with reference to written information relating to such Initial Purchaser furnished to the Issuer, the Company or any Guarantor by or on behalf of such Initial Purchaser through the Representatives specifically for inclusion in the Preliminary Memorandum or the Final Memorandum (or in any amendment or supplement thereto). This indemnity agreement will be in addition to any liability which any Initial Purchaser may otherwise have. Each of the Issuer, the Company and the Guarantors acknowledges that the statements set forth in the paragraph related to stabilization, syndicate covering transactions and penalty bids on page 127 of the Preliminary Memorandum and the Final Memorandum, constitute the only information furnished in writing by or on behalf of the Initial Purchasers for inclusion in the Preliminary Memorandum or the Final Memorandum (or in any amendment or supplement thereto). (c) Promptly after receipt by an indemnified party under this Section 8 of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against the indemnifying party under this Section 8, notify the indemnifying party in writing of the commencement thereof; but the failure so to notify the indemnifying party (i) will not relieve it from liability under paragraph (a) or (b) above unless and to the extent it did not otherwise learn of such action and such failure results in the forfeiture by the indemnifying party of substantial rights and defenses; and (ii) will not, in any event, relieve the indemnifying party from any obligations to any indemnified party other than the indemnification obligation provided in paragraph (a) or (b) above. The indemnifying party shall be entitled to appoint counsel of the indemnifying party's choice at the indemnifying party's expense to represent the indemnified party in any action for which indemnification is sought (in which case the indemnifying party shall not thereafter be responsible for the fees and expenses of any separate counsel retained by the indemnified party or parties except as set forth below); provided, however, that such counsel shall be satisfactory to the indemnified party. Notwithstanding the indemnifying party's election to appoint counsel to represent the indemnified party in an action, the indemnified party shall have the right to employ separate counsel (including local counsel), and the indemnifying party shall bear the reasonable fees, costs and expenses of such separate counsel if (i) the use of counsel chosen by the indemnifying ' represent the indemnified party would present such counsel with a conflict of interest; (ii) the actual or potential defendants in, or targets of, any such action include both the indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded that there may be legal defenses available to it and/or other indemnified parties which are different from or additional to those available to the indemnifying party; (iii) the indemnifying party shall not have employed counsel satisfactory to the indemnified party to 28 represent the indemnified party within a reasonable time after notice of the institution of such action; or (iv) the indemnifying party shall authorize the indemnified party to employ separate counsel at the expense of the indemnifying party. An indemnifying party will not, without the prior written consent of the indemnified parties, settle or compromise or consent to the entry of any judgment with respect to any pending or threatened claim, action, suit or proceeding in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified parties are actual or potential parties to such claim or action) unless such settlement, compromise or consent includes an unconditional release of each indemnified party from all liability arising out of such claim, action, suit or proceeding and does not involve any statement as to or any admission of fault, culpability or failure to act by or on behalf of any indemnified party. (d) In the event that the indemnity provided in paragraph (a) or (b) of this Section 8 is unavailable to or insufficient to hold harmless an indemnified party for any reason, the Issuer, the Company, the Guarantors and the Initial Purchasers agree to contribute to the aggregate losses, claims, damages and liabilities (including legal or other expenses reasonably incurred in connection with investigating or defending same) (collectively "Losses") to which the Issuer, the Company, the Guarantors and one or more of the Initial Purchasers may be subject in such proportion as is appropriate to reflect the relative benefits received by the Issuer, the Company and the Guarantors, taken as a whole, on the one hand and by the Initial Purchasers on the other from the offering of the Securities; provided, however, that in no case shall any Initial Purchaser (except as may be provided in any agreement among the Initial Purchasers relating to the offering of the Securities) be responsible for any amount in excess of the purchase discount or commission applicable to the Securities purchased by such Initial Purchaser hereunder. If the allocation provided by the immediately preceding sentence is unavailable for any reason, the Issuer, the Company, the Guarantors and the Initial Purchasers shall contribute in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of the Issuer, the Company and the Guarantor, taken as a whole, on the one hand and of the Initial Purchasers on the other in connection with the statements or omissions which resulted in such Losses, as well as any other relevant equitable considerations. Benefits received by each of the Issuer, the Company and the Guarantors shall be deemed to be equal to the total net proceeds from the offering (before deducting expenses) received by the Issuer, the Company and the Guarantors, taken as a whole, and benefits received by the Initial Purchasers shall be deemed to be equal to the total purchase discounts and commissions. Relative fault shall be determined by reference to, among other things, whether any untrue or any alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information provided by the Issuer, the Company and the Guarantors, taken as a whole, on the one hand or the Initial Purchasers on the other, the intent of the parties and their relative knowledge, access to information and opportunity to correct or prevent such untrue statement or omission. The Issuer, the Company, the Guarantors and the Initial Purchasers agree that it would not be just and equitable if contribution were determined by pro rata allocation or any other method of allocation which does not take account of the equitable considerations referred to above. Notwithstanding the provisions of this paragraph (d), no person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. For purposes of this Section 8, each person who controls an Initial Purchaser within the meaning of either the Act or the Exchange Act and each affiliate, director, officer, employee and agent of an Initial Purchaser shall have the same rights 29 to contribution as such Initial Purchaser, and each person who controls the Issuer, the Company or any Guarantor within the meaning of either the Act or the Exchange Act and each respective officer and director of each of the Issuer, the Company and the Guarantors shall have the same rights to contribution as each of the Issuer, the Company and the Guarantors, subject in each case to the applicable terms and conditions of this paragraph (d). The Initial Purchasers' obligations in this Section 8 to contribute are several in proportion to their respective underwriting obligations and not joint. 9. Default by an Initial Purchaser. If any one or more Initial Purchasers shall fail to purchase and pay for any of the Securities agreed to be purchased by such Initial Purchaser hereunder and such failure to purchase shall constitute a default in the performance of its or their obligations under this Agreement, the remaining Initial Purchasers shall be obligated severally to take up and pay for (in the respective proportions which the principal amount of Securities set forth opposite their names in Schedule I hereto bears to the aggregate principal amount of Securities set forth opposite the names of all the remaining Initial Purchasers) the Securities which the defaulting Initial Purchaser or Initial Purchasers agreed but failed to purchase; provided, however, that in the event that the aggregate principal amount of Securities which the defaulting Initial Purchaser or Initial Purchasers agreed but failed to purchase shall exceed 10% of the aggregate principal amount of Securities set forth in Schedule I hereto, the remaining Initial Purchasers shall have the right to purchase all, but shall not be under any obligation to purchase any, of the Securities, and if such nondefaulting Initial Purchasers do not purchase all the Securities, this Agreement will terminate without liability to any nondefaulting Initial Purchaser, the Issuer, the Company or any Guarantor. In the event of a default by any Initial Purchaser as set forth in this Section 9, the Closing Date shall be postponed for such period, not exceeding five Business Days, as the Representatives shall determine in order that the required changes in the Final Memorandum or in any other documents or arrangements may be effected. Nothing contained in this Agreement shall relieve any defaulting Initial Purchaser of its liability, if any, to the Issuer, the Company, any Guarantor or any nondefaulting Initial Purchaser for damages occasioned by its default hereunder. 10. Termination. This Agreement shall be subject to termination in the absolute discretion of the Representatives, by notice given to the Company prior to delivery of and payment for the Securities, if at any time prior to such time (i) trading in the Company's securities shall have been suspended by the Commission or the New York Stock Exchange or trading in securities generally on the New York Stock Exchange shall have been suspended or limited or minimum prices shall have been established on such Exchange; (ii) a banking moratorium shall have been declared either by Federal or New York State authorities; or (iii) there shall have occurred any outbreak or escalation of hostilities, declaration by the United States of a national emergency or war or other calamity or crisis the effect of which on financial markets is such as to make it, in the sole judgment of the Representatives, impracticable or inadvisable to proceed with the offering or delivery of the Securities as contemplated by the Final Memorandum (exclusive of any amendment or supplement thereto). 11. Representations and Indemnities to Survive. The respective agreements, representations, warranties, indemnities and other statements of each of the Issuer, the Company, the Guarantors or their respective officers and of the Initial Purchasers set forth in or made pursuant to this Agreement will remain in full force and effect, regardless of any investigation 30 made by or on behalf of the Initial Purchasers or the Issuer, the Company, any Guarantor or any of the officers, directors or controlling persons referred to in Section 8 hereof, and will survive delivery of and payment for the Securities. The provisions of Sections 7 and 8 hereof shall survive the termination or cancellation of this Agreement. 12. Notices. All communications hereunder will be in writing and effective only on receipt, and, if sent to the Representatives, will be mailed, delivered or telefaxed to the Citigroup Global Markets Inc., General Counsel (fax no.: (212) 816-7912) and confirmed to the General Counsel Citigroup Global Markets Inc., at 388 Greenwich Street, New York, New York 10013, Attention: General Counsel; or, if sent to the Issuer, the Company or any Guarantor, will be mailed, delivered or telefaxed and confirmed to it at Arch Coal Inc., CityPlace One, Suite 300, St. Louis, Missouri 63141, Attention: General Counsel (fax no.: (314) 994-2734). 13. Successors. This Agreement will inure to the benefit of and be binding upon the parties hereto and their respective successors and the officers and directors and controlling persons referred to in Section 8 hereof, and, except as expressly set forth in Section 5(h) hereof, no other person will have any right or obligation hereunder. 14. Applicable Law. This Agreement will be governed by and construed in accordance with the laws of the State of New York applicable to contracts made and to be performed within the State of New York. 15. Counterparts. This Agreement may be executed in one or more counterparts, each of which shall constitute an original and all of which together shall constitute one and the same instrument. 16. Headings.
