Ladies and Gentlemen:

▇▇▇▇▇▇▇▇▇▇▇▇ Escrow Corporation, a Delaware corporation (the “Issuer”) and wholly owned subsidiary of ▇▇▇▇▇▇▇▇▇▇▇▇ Coal Company, a Delaware corporation (the “Company”), proposes, upon the terms and conditions set forth in this purchase agreement (the “Agreement”), to issue and sell to you, as the initial purchasers (the “Initial Purchasers”), $425 million aggregate principal amount of its 10.750% Senior Secured Notes (the “Notes”). The Notes will (i) have terms and provisions that are summarized in the Offering Memorandum (as defined below) and (ii) are to be issued pursuant to an Indenture (the “Indenture”) to be entered into among the Issuer and ▇▇▇▇▇ Fargo Bank, National Association, as trustee (the “Trustee”).

The Notes are being issued and sold in connection with (i) the Company’s acquisition (the “Acquisition”) of two subsidiaries of Sherritt International Corporation (“Sherritt”), Prairie Mines & Royalty Ltd. (“PMRL”) and Coal Valley Resources Inc. (“CVRI” and together with PMRL, the “Sherritt Entities”), pursuant to an Arrangement Agreement, dated December 24, 2013, between the Company, its Canadian subsidiary, ▇▇▇▇▇▇▇▇▇▇▇▇ Canada Holdings, Inc., Sherritt, Altius Minerals Corporation and the other parties thereto (the “Arrangement Agreement”) and (ii) the related prepayment of the 8.02% senior secured notes issued by ▇▇▇▇▇▇▇▇▇▇▇▇ Mining LLC, a wholly-owned subsidiary of the Company (the “WML Notes”). The date on which the Company disburses the purchase price for the Acquisition is referred to herein as the “Acquisition Closing Date”.

On or promptly following the Acquisition Closing Date, the Notes will be automatically exchanged (the “Exchange”) for $425 million aggregate principal amount of 10.750% Senior Secured Notes due 2018 (the “New Notes”, it being understood that after the Acquisition Closing Date, references to “Notes” means the New Notes) issued by the Company and

▇▇▇▇▇▇▇▇▇▇▇▇ Partners, a Virginia partnership and indirect wholly owned subsidiary of the Company (“Partners”), as co-issuers. The Company and Partners previously issued $275 million in aggregate principal amount (of which $251.5 million principal amount remains outstanding) of 10.750% Senior Secured Notes due 2018 (the “Existing Notes”) pursuant to an indenture among the Company, Partners, the Guarantors (as defined below) and the Trustee, dated as of February 4, 2011(as heretofore amended or supplemented, the “Existing Indenture”). The New Notes will, at the time of issuance, will be equal in right of payment with, and be of the same series as, the Existing Notes and will be treated as a single class of securities with the Existing Notes for all purposes under the Existing Indenture. As of the Acquisition Closing Date, the New Notes will have the benefit of a security interest in the assets of the Company, Partners and certain subsidiaries of the Company (collectively, the “Grantors”) as described in the Pricing Disclosure Package and the Offering Memorandum (the “Collateral”). Pledge and security agreements, mortgages, collateral assignments and other documents or instruments that exist or are entered into in connection with the New Notes evidencing or purporting to create a security interest in and/or lien on the Collateral in favor of the notes collateral agent shall be hereinafter referred to as the “Security Documents.”

Upon the completion of the Acquisition, each of the Guarantors will fully, unconditionally and irrevocably guarantee (the “Guarantees”) the New Notes. The representations, warranties, agreements and obligations made by the Company, Partners and the Guarantors herein shall not become effective until the completion of the Acquisition, at which time such representations, warranties, agreements and obligations shall become effective pursuant to the terms of the Joinder Agreement. Thereafter all representations, warranties, agreements and obligations of the Issuer, the Company and the Guarantors shall be joint and several.

On February 7, 2014, the date of delivery and payment of the Notes pursuant to Section 5 hereof, (such date, the “Closing Date”), the Issuer will enter into an escrow and security agreement, substantially in the form attached hereto as Exhibit C (the “Escrow Agreement”), and will deposit, or cause to be deposited, in cash into an escrow account (the “Escrow Account”) with ▇▇▇▇▇ Fargo Bank, National Association, as escrow agent (the “Escrow Agent”), (a) the gross proceeds of the offering of the Notes and (b) an additional amount representing principal accretion (if any), an additional 1.0% of the gross proceeds of the notes and the amount of interest that will accrue on the Notes from the Closing Date to, but not including, the sixth business day after March 31, 2014 (the “First Additional Escrow Amount”). If the Acquisition Closing Date has not occurred on or prior to March 31, 2014 the Company will deposit an additional amount representing principal accretion (if any) and the amount of interest that will accrue on the Notes from the sixth day after March 31, 2014 to, but

The Issuer as of the date hereof agrees, and upon execution and delivery of the Joinder Agreement, the Company, Partners and each Guarantor, hereby agree, jointly and severally, to indemnify and hold harmless each Initial Purchaser, its directors, officers and employees and each person, if any, who controls such Initial Purchasers within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, from and against any loss, claim, damage or liability, joint or several, or any action in respect thereof (including, but not limited to, any loss, claim, damage, liability or action relating to purchases and sales of Notes), to which the Initial Purchasers or any director, officer,

employee or controlling person may become subject, under the Securities Act or otherwise, insofar as such loss, claim, damage, liability or action arises out of, or is based upon, (i) any untrue statement or alleged untrue statement of a material fact contained (A) in any Free Writing Offering Document, the Preliminary Offering Memorandum, the Pricing Disclosure Package or the Offering Memorandum or in any amendment or supplement thereto, (B) in any Blue Sky application or other document prepared or executed by the Company, Partners or any Guarantor (or based upon any written information furnished by the Issuer, the Company, Partners or any Guarantor) specifically for the purpose of qualifying any or all of the Notes under the securities laws of any state or other jurisdiction (any such application, document or information being hereinafter called a “Blue Sky Application”) or (C) in any materials or information provided to investors by, or with the approval of, the Issuer, the Company or Partners in connection with the marketing of the offering of the Notes (“Marketing Materials”), including any roadshow or investor presentations made to investors by the Issuer, the Company or Partners (whether in person or electronically), or (ii) the omission or alleged omission to state in any Free Writing Offering Document, the Preliminary Offering Memorandum, the Pricing Disclosure Package or the Offering Memorandum, or in any amendment or supplement thereto, or in any Blue Sky Application or in any Marketing Materials, any material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading and shall reimburse the Initial Purchasers and each such director, officer, employee or controlling person promptly upon demand for any legal or other expenses reasonably incurred by the Initial Purchasers or any director, officer, employee or controlling person in connection with investigating, defending or preparing to defend against, or participating as a third party witness with respect to any such loss, claim, damage, liability or action as such expenses are incurred; provided, however, that the Issuer, the Company, Partners and the Guarantors shall not be liable in such case to the extent that such loss, claim, damage, liability or action resulted directly from any untrue statement or alleged untrue statement or omission or alleged omission made in any Preliminary Offering Memorandum, the Pricing Disclosure Package or Offering Memorandum, or in any such amendment or supplement thereto, or in any Blue Sky Application or in any Marketing Materials, in reliance upon and in conformity with written information concerning the Initial Purchasers furnished to the Issuer, the Company or Partners by the Initial Purchasers specifically for inclusion therein, which information consists solely of the information specified in Section 9(e). The foregoing indemnity agreement is in addition to any liability that the Issuer, the Company, Partners or the Guarantors may otherwise have to the Initial Purchasers or to any director, officer, employee or controlling person of the Initial Purchasers.

(b)Indemnification of the Issuer, the Company, Partners and the Guarantors. Each Initial Purchasers hereby agrees, severally and not jointly, to indemnify and hold harmless (i) as of the date hereof, the Issuer and each of its directors and officers, and, upon execution and delivery of the Joinder Agreement, the Company, Partners, each Guarantor and each of their respective directors and officers and (ii) each person, if any, who controls, as of the date hereof, the Issuer and, upon execution and delivery of the Joinder Agreement, the Company, Partners or any Guarantor within the meaning of Section 15 of the Securities Act, from and against any loss, claim, damage or liability, joint or several, or any action in respect thereof, to which the Issuer, the Company, Partners, any Guarantor or any such director, officer, employee or controlling person may become subject, under the Securities Act or otherwise, insofar as such loss, claim, damage, liability or action resulted directly from (i) an untrue statement or alleged untrue statement of a material fact contained (A) in any Free Writing Offering Document, Preliminary

Offering Memorandum, the Pricing Disclosure Package or the Offering Memorandum or in any amendment or supplement thereto, (B) in any Blue Sky Application, or (C) in any Marketing Materials or (ii) the omission or alleged omission to state in any Free Writing Offering Document, Preliminary Offering Memorandum, the Pricing Disclosure Package or the Offering Memorandum, or in any amendment or supplement thereto, or in any Blue Sky Application or in any Marketing Materials any material fact necessary to make the statements therein not misleading, but in each case only to the extent that the untrue statement or alleged untrue statement or omission or alleged omission was made in reliance upon and in conformity with written information concerning the Initial Purchasers furnished to the Issuers by the Initial Purchasers specifically for inclusion therein, which information is limited to the information set forth in Section 9(e). The foregoing indemnity agreement is in addition to any liability that the Initial Purchasers may otherwise have to the Issuer, the Company, Partners, any Guarantor or any such director, officer, employee or controlling person.

(c)Notice and Procedures. Promptly after receipt by an indemnified party under this Section 9 of notice of any claim or the commencement of any action, the indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party under this Section 9, notify the indemnifying party in writing of the claim or the commencement of that action; provided, however, that the failure to notify the indemnifying party shall not relieve it from any liability that it may have under this Section 9 except to the extent it has been materially prejudiced by such failure, and; provided, further, that the failure to notify the indemnifying party shall not relieve it from any liability that it may have to an indemnified party otherwise than under this Section 9. If any such claim or action shall be brought against an indemnified party, and it shall notify the indemnifying party thereof, the indemnifying party shall be entitled to participate therein and, to the extent that it wishes, jointly with any other similarly notified indemnifying party, to assume the defense thereof with counsel reasonably satisfactory to the indemnified party. After notice from the indemnifying party to the indemnified party of its election to assume the defense of such claim or action, the indemnifying party shall not be liable to the indemnified party under this Section 9 for any legal or other expenses subsequently incurred by the indemnified party in connection with the defense thereof other than reasonable costs of investigation; provided, however, that the Initial Purchasers shall have the right to employ one counsel (in addition to any local counsel) to represent jointly the Initial Purchasers and their respective directors, officers, employees and controlling persons who may be subject to liability arising out of any claim in respect of which indemnity may be sought by the Initial Purchasers against the Issuer, the Company, Partners or any Guarantor under this Section 9, if (i) the Issuer, the Company, Partners, the Guarantors and the Initial Purchasers shall have so mutually agreed; (ii) the Issuer, the Company, Partners and the Guarantors have failed within a reasonable time to retain counsel reasonably satisfactory to the Initial Purchasers; (iii) the Initial Purchasers and their respective directors, officers, employees and controlling persons shall have reasonably concluded, based on the advice of counsel, that there may be legal defenses available to them that are different from or in addition to those available to the Issuer, the Company, Partners and the Guarantors; or (iv) the named parties in any such proceeding (including any impleaded parties) include both the Initial Purchasers or their respective directors, officers, employees or controlling persons, on the one hand, and the Issuer, the Company, Partners and the Guarantors, on the other hand, and representation of both sets of parties by the same counsel would present a conflict due to actual or potential differing interests between them, and in any such event the fees and expenses of such separate counsel (in addition to any local counsel) shall

be paid by the Issuer, the Company, Partners and the Guarantors. No indemnifying party shall (i) without the prior written consent of the indemnified parties (which consent shall not be unreasonably withheld), 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 (x) includes an unconditional release of each indemnified party from all liability arising out of such claim, action, suit or proceeding and (y) does not include any statement as to an admission of fault, culpability or failure to act by or on behalf of any indemnified party, or (ii) be liable for any settlement of any such action effected without its written consent (which consent shall not be unreasonably withheld), but if settled with the consent of the indemnifying party or if there be a final judgment of the plaintiff in any such action, the indemnifying party agrees to indemnify and hold harmless any indemnified party from and against any loss or liability by reason of such settlement or judgment.

(d)Contribution. If the indemnification provided for in this Section 9 shall for any reason be unavailable to or insufficient to hold harmless an indemnified party under Section 9(a) or 9(b) in respect of any loss, claim, damage or liability, or any action in respect thereof, referred to therein, then each indemnifying party shall, in lieu of indemnifying such indemnified party, contribute to the amount paid or payable by such indemnified party as a result of such loss, claim, damage or liability, or action in respect thereof, (i) in such proportion as shall be appropriate to reflect the relative benefits received by the Issuer, the Company, Partners and the Guarantors, on the one hand, and the Initial Purchasers, on the other, from the offering of the Notes or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Issuer, the Company, Partners and the Guarantors, on the one hand, and the Initial Purchasers, on the other, with respect to the statements or omissions that resulted in such loss, claim, damage or liability, or action in respect thereof, as well as any other relevant equitable considerations. The relative benefits received by the Issuer, the Company, Partners and the Guarantors, on the one hand, and the Initial Purchasers, on the other, with respect to such offering shall be deemed to be in the same proportion as the total net proceeds from the offering of the Notes purchased under this Agreement (before deducting expenses) received by the Issuer, the Company, Partners and the Guarantors, on the one hand, and the total underwriting discounts and commissions received by the Initial Purchasers with respect to the Notes purchased under this Agreement, on the other hand, bear to the total gross proceeds from the offering of the Notes under this Agreement as set forth on the cover page of the Offering Memorandum. The relative fault shall be determined by reference to whether the untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact relates to information supplied by the Issuer, the Company, Partners, the Guarantors, or the Initial Purchasers, the intent of the parties and their relative knowledge, access to information and opportunity to correct or prevent such statement or omission. For purposes of the preceding two sentences, the net proceeds deemed to be received by the Issuer shall be deemed to be also for the benefit of the Company, Partners and the Guarantors, and information supplied by the Issuer shall also be deemed to have been supplied by the Company, Partners and the Guarantors. The Issuer, the Company, Partners, the Guarantors, and the Initial Purchasers agree that it would not be just and equitable if contributions pursuant to this Section 9(d) were to be determined by pro rata allocation or by any other method of allocation that does not take into account the

equitable considerations referred to herein. The amount paid or payable by an indemnified party as a result of the loss, claim, damage or liability, or action in respect thereof, referred to above in this Section 9(d) shall be deemed to include, for purposes of this Section 9(d), any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 9(d), the Initial Purchasers shall not be required to contribute any amount in excess of the amount by which of the commissions received by it exceeds the amount of any damages that the Initial Purchasers have otherwise paid or become liable to pay by reason of any untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(t) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation.

(e)The Initial Purchasers confirm and the Issuer acknowledges and agrees that the statements with respect to the offering of the Notes by the Initial Purchasers set forth under the caption “Plan of Distribution” in the third paragraph, the first three sentences of the fourth paragraph, the seventh paragraph and the first and second sentences of the eighth paragraph, in each case, contained in the Preliminary Offering Memorandum, the Pricing Disclosure Package and the Offering Memorandum constitute the only information concerning the Initial Purchasers furnished in writing to the Issuer, the Company, Partners or any Guarantor by or on behalf of the Initial Purchasers specifically for inclusion in the Preliminary Offering Memorandum, the Pricing Disclosure Package and the Offering Memorandum or in any amendment or supplement thereto.

10.Termination. The obligations of the Initial Purchasers hereunder may be terminated by the Initial Purchasers by notice given to and received by the Issuers prior to delivery of and payment for the Notes if, prior to that time, (a) the Issuer, the Company, Partners or the Guarantors, as the case may be, will have failed, refused or been unable, at or prior to delivery of and payment for the Notes, to perform any agreement on its part to be performed hereunder, (b) any of the events described in Section 8(m) shall have occurred or (c) any other condition to the Initial Purchasers’ obligations hereunder is not fulfilled or the Initial Purchasers shall decline to purchase the Notes for any reason permitted under this Agreement.

11.Reimbursement of Initial Purchasers’ Expenses. If (a) the Issuer fails to tender the Notes for delivery to the Initial Purchasers by reason of any failure, refusal or inability on the part of the Issuer, the Company, Partners or any Guarantor to perform any agreement on their part to be performed, or because any other condition of the obligations hereunder required to be fulfilled by the Issuer, the Company, Partners or any Guarantor is not fulfilled or (b) the Initial Purchasers shall decline to purchase the Notes for any reason permitted under this Agreement, the Issuer, the Company, Partners and the Guarantors shall reimburse the Initial Purchasers for all reasonable expenses described in Section 7 and incurred by the Initial Purchasers in connection with this Agreement and the proposed purchase of the Notes, and upon demand the Issuer, the Company, Partners and the Guarantors shall pay the full amount thereof to the Initial Purchasers.

12.Notices, etc. All statements, requests, notices and agreements hereunder shall be in writing, and:
