2. The WRI Membership Interest. The “WRI Membership Interest” shall be WRI’s entire right, title and interest as a member of Absaloka. WRI, WRI Sub and Investor agree that, after giving effect to the transactions contemplated herein, WRI shall no longer be a member of Absaloka, and WRI Sub and Investor shall have the respective Membership Interests in Absaloka as are set forth in the Restated Operating Agreement.

3. Closing Date. The closing of the purchase and sale of the WRI Membership Interest and the granting of the Investor Options (the “Closing”) shall be held at the offices of Xxxxx Xxxxxx & Xxxxxx LLP, 0000 Xxxxxxxxxxx Xxxxxx, Xxxxxx, Xxxxxxxx on October 16, 2008 or at such other date and place as the parties shall agree.

4. Consideration for Purchase of WRI Membership Interest. In consideration of the purchase of the WRI Membership Interest, Investor shall deliver to WRI the Equity Payment (as defined in Section 4.1) and the Fixed Payment Note and shall assume the Contingent Payment Obligation (as defined in Section 4.2).

4.1 Equity Payment. The cash portion of the purchase price for the WRI Membership Interest shall be $4,000,000 (the “Equity Payment”), payable by wire transfer of immediately available funds as follows: (a) Investor shall pay $2,000,000 of the Equity Payment to WRI in cash at the Closing; and (b) Investor shall pay the remaining $2,000,000 of the Equity Payment in cash into an escrow account with First Interstate Bank, as escrow agent, pursuant to an escrow agreement substantially in the form of Exhibit C hereto (the “Approval Escrow”), pending the following (the “Second Payment Conditions”): (A) receipt of the following on or prior to April 1, 2009: (i) receipt from the Internal Revenue Service (“IRS”) of a private letter ruling (the “Private Letter Ruling”) granting, to Investor’s and WRI’s reasonable satisfaction, the rulings requested in the Private Letter Ruling Request attached as Exhibit D hereto (a “Favorable Ruling”); (ii) receipt by Absaloka of approval of the Second Crow Lease and the Crow Sublease from the Bureau of Indian Affairs (“BIA Approval”); and (iii) assignment of contracts for the sale of coal produced from the Sublease representing at least 90% of the production subject to sales contracts from the Absaloka Mine to which WRI is a party and (B) at April 1, 2009, none of WRI, WCC, Investor, nor Investor Parent (as defined in Section 4.2(e) below), shall have commenced a voluntary bankruptcy proceeding or consented to the appointment of a receiver, liquidator, assignee, custodian, or trustee for the purpose of winding up its affairs. The satisfaction or waiver of the Second Payment Conditions shall be determined in accordance with the procedures set forth in Section 6.

4.2 Deferred Payments.

(a) At the Closing, Investor (i) shall execute and deliver to WRI a promissory note substantially in the form of Exhibit E hereto (the “Fixed Payment Note,” amounts payable in respect of which being referred to as the “Fixed Payment Obligation”) and (ii) shall assume the Contingent Payment Obligation substantially in the form of Exhibit F (collectively, the Contingent Payment Obligation and the Fixed Payment Note shall be referred to as the “Deferred Payment Notes,” the Contingent Payment Obligation and the Fixed Payment Obligation shall be referred to as the “Deferred Payment Obligations,” and payments made pursuant to the Deferred Payment Obligations shall be referred to as the “Deferred Payments”).

(b) Under the Fixed Payment Note, and subject to the terms thereof, Investor shall pay to WRI $2,000,000 each calendar quarter (prorated for each partial quarter), which amount shall be inclusive of accrued interest at a rate of 10% per annum on the unpaid balance of the Fixed Payment Note; provided, however, that such amount shall be increased by the amount of any Fixed Payment Note payment postponed from a prior calendar quarter pursuant to the terms of the Fixed Payment Note. Payments under the Fixed Payment Note will be payable in arrears commencing with a payment for the quarter ended December 31, 2008, until the earlier of (i) total principal payments of $27,215,982 having been made, and (ii) December 31, 2012 (the “Maturity Date”). On the Maturity Date, all remaining principal and accrued interest on the Fixed Payment Note shall become due and payable. The Fixed Payment Note may not be prepaid.

(c) The Contingent Payment Obligation is based on the amount of Indian Coal Production Tax Credits (the “Indian Coal Production Tax Credits”), as determined under Section 45(e) of the Internal Revenue Code of 1986, as amended (the “IRC” or “Code”),

attributable to Absaloka’s production and sale of Indian coal, within the meaning of Section 45(e)(9) of the Code (“Indian Coal”) from the Sublease, that is allocated to Investor pursuant to the Restated Operating Agreement. Under the Contingent Payment Obligation, and subject to the terms thereof, Investor is required pay to WRI for each calendar quarter an amount equal to the excess of (i) 90% of the Indian Coal Production Tax Credits that have been allocated by Absaloka to Investor under the Restated Operating Agreement during the immediately preceding calendar quarter over (ii) aggregate payments made to WRI or into the Approval Escrow, as provided for in subsection (d) below, as applicable, including interest, under the Fixed Payment Note in respect of such quarter. The amount of Indian Coal Production Tax Credits allocated to Investor by Absaloka for each calendar quarter shall be set forth in the Quarterly Report provided for in Section 14.1.

(d) Investor shall make the Deferred Payments to WRI by wire transfer of immediately available funds to an account designated in writing by WRI. Deferred Payments shall be made within ten (10) Business Days after receipt by Investor of an invoice (the “Invoice”) from WRI (a copy of which shall be delivered to Absaloka) delivered after the end of each calendar quarter, which Invoice shall include the Quarterly Report and indicate accrued amounts payable under each of the Deferred Payments, with payments under the Fixed Payment Note to be applied first to accrued and unpaid interest and thereafter to outstanding principal; provided, however, that any Deferred Payments shall be paid into the Approval Escrow until the satisfaction or waiver of the Second Payment Conditions in accordance with the procedures set forth in Section 6. Upon the satisfaction or waiver of the Second Payment Conditions, all amounts held in the Approval Escrow, including any earnings therein, shall be paid to WRI.

(e) The Deferred Payment Obligations shall be recourse obligations of Investor and shall be secured by a pledge by Investor to WRI of Investor’s entire Membership Interest in Absaloka pursuant to a Pledge Agreement substantially in the form of Exhibit G hereto (the “Investor Pledge”). In addition, an affiliate of Investor that is the direct or indirect owner of 100% of the issued and outstanding membership interests of Investor (“Investor Parent”), shall be obligated, pursuant to a Guaranty substantially in the form of Exhibit H hereto (the “Investor Parent Guaranty”), to guaranty the payment by Investor of all Deferred Payments. The amount of the guaranty shall be limited to 90% of the Indian Coal Production Tax Credits allocated by Absaloka to Investor in respect of the period covered by the Invoice, subject to the aggregate limit set forth below (the “Guaranteed Amount”). The Guaranteed Amount in respect of any calendar quarter shall be reduced by the amount of any cash distributions made by Absaloka (including tax distributions) to Investor during such calendar quarter which are applied by Investor toward payment of the Deferred Payment Obligations, or paid to Absaloka in the event of a Cash Deficit, as provided for in subsection (f) below. The aggregate Guaranteed Amount is limited to the lesser of (i) $70,000,000 or (ii) 90% of the cumulative Indian Coal Production Tax Credits allocated by Absaloka to Investor reduced by the amount of all cash distributions made by Absaloka (including tax distributions) to Investor at any time which are or were applied by Investor toward payment of the Deferred Payment Obligations, or paid to Absaloka in the event of a Cash Deficit, as provided for in subsection (f) below.

(f) If at any time after satisfaction or waiver of the Second Payment Conditions the Manager of Absaloka notifies Investor and WRI in writing that Absaloka is experiencing a Cash Deficit (as defined in the Restated Operating Agreement), Investor shall thereafter make the Deferred Payments directly to Absaloka until it is notified by the Manager of

Absaloka in writing that Absaloka no longer is experiencing a Cash Deficit. WRI shall treat such payment to Absaloka as satisfying an equal amount of any accrued and unpaid Deferred Payment Obligations. Investor shall notify WRI of the amount and timing of such payments to Absaloka. Absaloka shall treat such payments as a loan from WRI to Absaloka, pursuant to the provisions of Section 4.6(c) of the Restated Operating Agreement, to be repaid out of first available funds of Absaloka.

(g) The following shall constitute Termination Events, the occurrence of which will terminate the Deferred Payment Obligations in accordance with their terms, the Investor Pledge and the Investor Parent Guaranty:

(i) the exercise by Investor or WRI of the right to require transfer of Investor’s Membership Interest in accordance with the provisions of Section 6 of this Agreement; or

(ii) a Breach Liquidation of Absaloka in accordance with the provisions of Section 7 of this Agreement or the terms of the Restated Operating Agreement.

(h) The following shall constitute Credit Termination Events, the occurrence of which will terminate the Investor Pledge, the Investor Parent Guaranty, and the Contingent Payment Obligation, and cause the Fixed Payment Obligation to be suspended until Cash Payout or withdrawal by Investor occurs:

(i) a Disqualification Event or a Disallowance Event, as provided under Section 12 of this Agreement; or

(ii) the enactment of an amendment in or to the Code that eliminates the Indian Coal Production Tax Credits that are available to Absaloka from the production and sale of coal from the Sublease (“Change in Law”).

(i) If Absaloka does not provide tax information to Investor by April 1 of any year, as required by Section 7.1(b)(v) of the Restated Operating Agreement, Investor shall be entitled to suspend the Deferred Payments until such tax information is received. Upon receipt of such tax information, Investor shall pay to WRI the full amount of any suspended Deferred Payments.

5. Option to Acquire Additional Membership Interests.

(a) WRI Sub hereby grants to Investor options, exercisable up to five times, with each exercise occurring prior to December 31, 2012 (the “Investor Options”) to purchase additional membership interests in Absaloka (the “Option Interests”). Each Option may be exercised for a purchase price of $1,000,000 (the “Option Price”). Upon exercise of the Investor Option, Payout and Cash Payout shall be extended in accordance with Section 5.2(e) of the Restated Operating Agreement.

(b) Each Option shall become exercisable upon receipt by Investor of notice from Absaloka, given pursuant to Section 7.1(b)(vi) of the Restated Operating Agreement, that a Projected Payout Date (as defined in the Restated Operating Agreement) is expected to occur within 75 days (the “Projected Payout Date Notice”), and shall be exercisable only if Investor is not then in default under this Agreement, the Restated Operating Agreement, the Contingent Payment Obligation or the Fixed Payment Note. Each Option shall be exercised by delivery by Investor to WRI Sub (with a copy to Absaloka) of a notice (the “Option Notice”) within 60 days of receipt of the Projected Payout Date Notice, during which period, pursuant to the terms of the

Restated Operating Agreement, Payout may not occur. The acquisition by Investor of any Option Interest shall become effective upon WRI Sub’s receipt of (i) the Option Notice, and (ii) the Option Price, which shall be due and payable no later than five (5) days following the date of the Option Notice by wire transfer of immediately available funds to an account designated by WRI Sub. Should Investor exercise any Option, WRI Sub shall execute and deliver to Investor concurrently with payment of the Option Price an assignment of the Option Interest, free and clear of all Liens and encumbrances created by, through or under WRI Sub, in a form substantially similar to the Member Assignment.

(c) The Investor Option shall be extinguished during a Credit Disallowance Period (as defined in the Restated Operating Agreement).

6. Failure to Satisfy Second Payment Condition: Right of Investor and WRI to Require Transfer of Membership Interest.

6.1 If the Second Payment Conditions are not satisfied or waived by April 1, 2009, Investor shall be entitled, on or before April 15, 2009, and WRI shall be entitled, on or before April 30, 2009, to require that Investor sell, and WRI purchase, all of Investor’s WRI Membership Interest. If either Investor or WRI make such election, the electing party shall notify the other party and Absaloka on or before April 15, 2009 or April 30, 2009, respectively, and, effective as of the date of such notice:

(a) The Restated Operating Agreement shall, automatically and without any further action, be amended and restated to (i) provide for allocations from (A) if the election was made on or before April 15, 2009, the date of the Restated Operating Agreement; or (B) if the election was made after April 15, 2009, January 1, 2009, of all items of Absaloka 99.9% to WRI Sub and 0.1% to Investor; and (ii) delete Section 6.5, and shall also otherwise be amended in the

discretion of the Manager of Absaloka; provided, however, that no amendment of the Restated Operating Agreement may impose obligations on Investor in respect of its remaining Membership Interest;

(b) in consideration of the purchase of Investor’s Membership Interest and retroactive reduction in allocations to Investor from Absaloka,

(i) WRI shall pay to Investor $2,000,000, net of 20% of any interest income recognized by WRI as a result of WRI’s ownership of the Approval Escrow for tax purposes;

(ii) amounts in the Approval Escrow shall be distributed to Investor;

(iii) the Deferred Payments shall be cancelled;

(iv) the Investor Options and the Coal Options shall be cancelled; and

(v) the Investor Parent Guaranty and the Investor Pledge shall be cancelled.

(c) WRI and Investor agree to execute joint instructions to the escrow agent to implement determinations made pursuant to this Section 6.

6.2 If Investor does not elect to require the transfer of Investor’s Membership Interest by April 15, 2009 and WRI does not make such election by April 30, 2009, the Second Payment Conditions shall be deemed to have been waived and amounts in the Approval Escrow shall be distributed to WRI.

6.3 If a Favorable Ruling is not received from the IRS, Investor’s sole remedy for breach of the tax representations set forth in Section 11.18 shall be the election to require the actions set forth in this Section 6.

7. Breach Liquidation.

7.1 Upon the occurrence of (i) a final, non-appealable determination by a court or other judicial body that WRI has acted with gross negligence or willful misconduct in its operation of the Absaloka Mine; (ii) any of the following occurrences where such occurrence has a Material Adverse Effect on Absaloka, (A) the invalidation, cancellation or other termination, or suspension of the Sublease or either of the First Crow Lease or Second Crow Lease, or any other agreement upon which the validity or effectiveness of any such Sublease or lease depends in whole or in part; (B) any modification, amendment, or reformation of or to any such Sublease, lease or other agreement; (C) any failure to obtain any required final, binding and nonappealable governmental approvals of any such Sublease, lease or other agreement or of mining plans or other permission or authority necessary for Absaloka to conduct the contemplated mining activities under the Sublease; or (D) failure to obtain a permit under the Surface Mining Control and Reclamation Act for lands within the Second Crow Lease by January 1, 2010; or (iii) the taking of any action under Section 6.5 of the Restated Operating Agreement without the consent of Investor (each, a “Breach Liquidation Event”), Investor shall be entitled to require the liquidation of Absaloka and to assert a claim against WRI as set forth in this Section 7. At the election of WRI, with the consent of Investor, not to be unreasonably withheld, conditioned or delayed, an Affiliate of WRI may satisfy WRI’s obligation under this Section 7.

7.2 Breach Liquidation Procedures. In the event of a Breach Liquidation:

(a) Absaloka’s assets shall be revalued in accordance with Treasury Regulations §1.704-1(b)(2)(iv)(f)(5)(ii) and the net profit or loss therefrom shall be allocated among the Members of Absaloka (without regard to any unexercised Investor Options or Coal Options) in accordance with Treasury Regulations §1.704-1(b)(2)(iv)(g). The capital accounts of

the Members immediately after this allocation shall be referred to herein as “Booked-Up Capital Accounts.”

(i) The value of the Sublease shall be determined by agreement of the Members.

(ii) If the Members are unable to agree on the value of the Sublease, the value shall be determined by Erhardt, Keefe, Xxxxxxx & Xxxxxxx PC (or such other person or firm as shall be reasonably acceptable to the Members), which shall value the Sublease (including any previously exercised Coal Options) at the Discounted Cash Flow Value thereof, in accordance with the provisions of the Restated Operating Agreement.

(b) Absaloka shall distribute to Investor an amount in cash equal to Investor’s Booked-Up Capital Account in full redemption and retirement of Investor’s interest in Absaloka; provided, however, that the portion of such distribution equal to (i) the remaining outstanding principal balance and accrued interest under the Fixed Payment Note at the date of the Breach Liquidation and (ii) the amount, if any, remaining payable by Investor to WRI in respect of the Contingent Payment Obligation for any period prior to the date of the Breach Liquidation, whether or not yet reflected in an Invoice, shall be paid to WRI on behalf of Investor before the remaining portion of the Booked-Up Capital Account is paid to Investor;

(c) If the total distributions made by Absaloka to Investor pursuant to the Restated Operating Agreement (but disregarding any portion of the distributions paid to WRI as a payment on the Fixed Payment Obligation pursuant to (b) above) would not trigger Cash Payout under the Restated Operating Agreement, WRI shall pay to Investor an amount which, if treated as a distribution by Absaloka to Investor, would be sufficient to cause Cash Payout under the Restated Operating Agreement (the “IRR Payment”);

(d) The Deferred Payment Notes will be cancelled;

(e) The Investor Parent Guaranty and Investor Pledge will be cancelled; and

(f) If Absaloka does not have sufficient cash to make a cash distribution to Investor as required under this Section 7, WRI shall lend Absaloka up to the amount of Investor’s Booked-Up Capital Account on the terms specified in the Restated Operating Agreement.

7.3 Procedure on Breach Liquidation Event. The Manager of Absaloka shall promptly notify Investor and WRI of the occurrence of a Breach Liquidation Event, which notice shall include a calculation of the Investor’s Booked-Up Capital Account as of the date of the Breach Liquidation Event, accompanied by a schedule of all distributions made by Absaloka to Investor for the period in which Investor has been a member of Absaloka (the “Absaloka Breach Liquidation Event Occurrence Notice”). Within ten (10) Business Days of receipt of the Absaloka Breach Liquidation Event Occurrence Notice, WRI shall send a notice to Investor and Absaloka informing them of the remaining balance under the Fixed Payment Note. Within ten (10) Business Days of receipt of all information, provided that Investor has paid all accrued Deferred Payments, Investor may elect to require the Breach Liquidation of Absaloka by notifying WRI and Absaloka in writing. Investor shall provide to WRI wire transfer instructions for the IRR Payment. The IRR Payment shall be made no later than ten (10) Business Days following the receipt by WRI from Investor of the notice of election. If Investor does not elect to require a Breach Liquidation within the time period set forth above, the rights of Investor in respect of a Breach Liquidation Event shall be deemed waived.

8. Withdrawal.

8.1 Investor shall be entitled to withdraw as a Member of Absaloka at any time. In the event that Investor provides written notice to Absaloka that it is electing to withdraw from Absaloka (the “Withdrawal Notice”), it shall be entitled to receive from Absaloka the amount of Investor’s Booked-Up Capital Account balance at the date of withdrawal, determined in accordance with the provisions of the Restated Operating Agreement; provided, however, that the portion of such distribution equal to (i) the remaining principal and accrued interest owing under the Fixed Payment Note at the date of withdrawal and (ii) the amount, if any, remaining payable by Investor to WRI in respect of the Contingent Payment Obligation for any period prior to the date of withdrawal, whether or not yet reflected in an Invoice, shall be paid to WRI on behalf of Investor before the remaining portion of the Booked-Up Capital Account is paid to Investor. WRI shall prepare an Invoice indicating amounts payable as of the date of withdrawal for any period not covered by an outstanding Invoice.

8.2 At the date of withdrawal, (i) the Contingent Payment Obligation will be cancelled and (ii) the Investor Parent Guaranty and the Investor Pledge will be cancelled. The Fixed Payment Note, to the extent not fully paid through the payments by Absaloka to WRI on behalf of Investor in accordance with the provisions of Section 8.1, shall continue to be an obligation of Investor.

9. WRI Buyout Option.

9.1 At any time from the fifth anniversary of the Closing until the sixth anniversary of the Closing (the “Buyout Period”), WRI shall have the option (the “Buyout Option”) to purchase the Membership Interest of Investor in Absaloka upon the terms set forth

herein. The Buyout Option, if exercised, must be exercised by WRI giving written notice (the “Buyout Notice”) to Investor and Absaloka of its election to exercise the Buyout Option.

9.2 The price payable under the Buyout Option (the “Buyout Price”) shall be an amount equal to the Investor’s Booked-Up Capital Account at the date of the Buyout Notice determined in accordance with the provisions of the Restated Operating Agreement, if exercised during the first three months following such fifth anniversary, or 120% of such Booked-Up Capital Account if exercised after the first three months following such fifth anniversary, in each case, reduced by remaining principal and interest owing under the Fixed Payment Note at the date of the Buyout Notice.

9.3 If a Buyout Notice is given pursuant to Section 9.1, Absaloka shall provide to WRI and Investor in writing within 20 days the Investor’s Booked-Up Capital Account as of the date of the Buyout Notice, determined in accordance with the provisions of the Restated Operating Agreement. The closing (the “Buyout Closing”) shall occur at a mutually convenient time and place no later than 30 days following the date the Buyout Notice is given. At the Buyout Closing, WRI or, at the election of WRI, an Affiliate of WRI selected by WRI, shall pay the Buyout Price, reduced for any distributions made to Investor by Absaloka between the date of the Buyout Notice and the Buyout Closing, and Investor shall assign all of its Membership Interest in Absaloka to WRI or the Affiliate, as applicable, free and clear of all Liens and encumbrances created by, through or under Investor, and shall execute a Member Assignment, substantially in the form of Exhibit A hereto. The Buyout Price shall be paid in cash, certified funds, or by wire transfer at closing.

9.4 From the date of the Buyout Notice, (i) the Contingent Payment Obligation shall be cancelled, and (ii) the Investor Parent Guaranty and the Investor Pledge will

be cancelled. The Fixed Payment Note, to the extent not fully paid through the offset against the Buyout Price, shall continue as an obligation of Investor.

In the ordinary course of business, each of WRI and Absaloka is current in its respective payments of all costs and expenses pertaining to the operation of the Absaloka Mine under the Sublease, except where such payments are being contested in good faith or except where the failure to make such payments would not have a Material Adverse Effect on the value of the WRI Membership Interest or the Option Interests.

11.21 Extension of 2004 Exploration Agreement. WRI has timely paid to the Crow Tribe the amount required to exercise and extend the exploration rights as required under Sections 5.3 and 5.4 of the Exploration and Option to Lease Agreement dated February 13, 2004 between WRI and the Crow Tribe (the “2004 Exploration Agreement”).

12.1 Private Letter Ruling. On October 3, 2008, Absaloka requested the Private Letter Ruling from the IRS in the form of Exhibit D hereto requesting rulings that:

(a) Absaloka’s interest in the Sublease qualifies as an economic interest in minerals in place within the meaning of Treas. Reg. § 1.611-1(b)(1) and not as a production payment under IRC § 636 and Treas. Reg. § 1.636-3;

(b) Production from the Crow Reserves qualifies as “Indian coal” within the meaning of IRC § 45(c)(9);

(c) Absaloka will be the producer (as that term is used in IRC § 45(e)(10)(A)) of Indian coal from an Indian coal production facility (as that term is used in IRC § 45(d)(10)) with respect to production under the Sublease;

(d) The Crow Tribe will not be entitled to any of the credits available under IRC § 45(e)(10) from the activities of Absaloka;

(e) The Sublease will comprise a single Indian coal production facility for purposes of IRC §§ 45(d)(10) and 45(e)(10); and

(f) Investor’s interest in Absaloka will not constitute a production payment under IRC § 636.

12.2 Procedure for Private Letter Ruling. All costs associated with the Private Letter Ruling shall be borne by WRI. Absaloka shall provide Investor with copies of all documents provided to the IRS or the Treasury Department in connection with the request for a Private Letter Ruling. Investor shall have no remedy or recourse against WRI or Absaloka under this Agreement if the Private Letter Ruling is not acceptable to Investor, except as expressly set forth herein or in the Restated Operating Agreement. Investor shall, in good faith, cooperate with Absaloka’s efforts to acquire a Private Letter Ruling and shall amend this Agreement and the documents contemplated hereunder in order that Absaloka may obtain a Favorable Ruling, if, in the reasonable discretion of each of Investor and WRI, such amendments will not have a Material Adverse Effect on WRI, Absaloka or Investor.

12.3 Escrow in the Event of Tax Audit. Promptly following the written notice of commencement of any IRS audit of Absaloka wherein the IRS asserts, proposes to assert, or may assert that the Indian Coal produced and sold by Absaloka does not qualify for Indian Coal Production Tax Credits or that Investor is not entitled to its allocable share of Indian Coal Production Tax Credits from Absaloka, whether or not such assertion or proposed assertion relates to periods prior to the purchase of the WRI Membership Interest contemplated hereunder (such audit to be referred to as a “Tax Audit” and the date of receipt of written notice, the “Escrow Commencement Date”), Investor and WRI shall enter into an escrow agreement with an escrow agent, substantially in the form of Exhibit I (the “IRS Audit Escrow Agreement”). The IRS Audit Escrow Agreement and the funds in the IRS Audit Escrow Account established pursuant thereto shall be administered in accordance with the following provisions:

(a) Beginning with the commencement of the calendar quarter in which the Escrow Commencement Date occurs and continuing for each calendar quarter until the “Conclusion of a Tax Audit” (as that term is defined below, with such period of time being the “Escrow Period”), Investor shall deposit into the IRS Audit Escrow Account all Deferred Payments for each such calendar quarter (the “IRS Audit Escrow Amount” and the sum of all IRS Audit Escrow Amounts being the “Escrowed Funds”). WRI shall be treated as the owner of the Escrowed Funds for federal income tax purposes.

(b) The “Conclusion of a Tax Audit” will be deemed to have occurred upon the earliest to occur of the following events: (i) the IRS provides written notice to Absaloka that it does not intend to assert claims against Absaloka or any member of Absaloka in respect of the Indian Coal Production Tax Credits, (ii) the receipt by Absaloka or any member of Absaloka of written notice from the IRS that it will not assert any adjustments with respect to the qualification or allocation of Indian Coal Production Tax Credits; (iii) a settlement agreement with the IRS which resolves the open federal income tax issues in connection with such audit; (iv) a judgment of a court of law or a decision in an administrative proceeding becoming non-appealable with respect to the federal income tax issues in connection with such audit; or (v) the expiration of the applicable period of limitations for making assessments with respect to the years under examination in the tax audit if the IRS has made no assessments within such period with respect to such issue.

(c) At the Conclusion of a Tax Audit, Investor and WRI agree to recalculate, based on the provisions of this Section 12.3(c), any amounts due to or owed by each of Investor and WRI pursuant to the terms of this Agreement. If, under the Conclusion of a Tax Audit,

(i) Coal produced and sold by Absaloka fails to qualify for the Indian Coal Production Tax Credit, whether or not the allocations thereof are allowed or disallowed (a “Disqualification Event”), as an adjustment to the purchase price for the WRI Membership Interest, (A) the Escrowed Funds, including accrued interest thereon, shall be paid to Investor, (B) WRI shall return to Investor all payments previously received in respect of the Deferred Payments, (C) the Contingent Payment Obligations, the Investor Options, the Investor Parent Guaranty and the Investor Pledge will be cancelled as of the date of the Conclusion of a Tax Audit, (D) no payment will be required under the Fixed Note Obligation until Investor has reached Cash Payout without regard to funds paid to Investor under this Section 12.3(c)(i), (E) Investor will not be entitled to require exercise of any unexercised Coal Options and (F) Investor’s Sharing Percentage (as defined in the Restated Operating Agreement) shall be reduced to 1% after Payout. Any payment by WRI to Investor pursuant to (B) above shall be made within five (5) Business Days following the Conclusion of a Tax Audit, or, may, at the election of WRI, be paid by means of a promissory note (the “Tax Payment Note”) delivered at such date and having the following characteristics:

(x) Six month maturity, subject to extension at the election of WRI for one additional six-month period, on the terms set forth in (y) below.

(y) Interest payable quarterly in advance at the prime rate published in the Money Rates section of the Wall Street Journal for the first Business Day of the week in which the Tax Payment Note is delivered, which rate shall increase to such prime rate plus 4% for the second six months, if WRI elects to extend the maturity; and

(z) Prepayable at any time at the election of WRI.

(ii) The allocation to Investor of Indian Coal Production Tax Credits is entirely disallowed (a “Disallowance Event”), (A) the Escrowed Funds, including accrued interest thereon, shall be paid to Investor, (B) the Contingent Payment Obligation, any unexercised Investor Options, the Investor Parent Guaranty and the Investor Pledge will be cancelled as of the date of the Conclusion of a Tax Audit, (C) no payment will be required under the Fixed Note Obligation until Investor has reached Cash Payout without regard to funds paid to Investor under this Section 12.3(c)(ii), (D) Investor will not be entitled to require exercise of any unexercised Coal Options and (E) Investor’s Sharing Percentage (as defined in the Restated Operating Agreement) shall be reduced after Payout to 1%.

(iii) If at the Conclusion of a Tax Audit, the IRS determines that a portion of the coal produced and sold by Absaloka qualifies for the Indian Coal Production Tax Credit and a portion does not qualify, and/or the allocations thereof to Investor are partially allowed and partially disallowed, the parties shall determine the amount to be received by Investor (the “Audit Overpayment”), as follows. First, the parties shall determine the excess, if any, of (i) Deferred Payments made from the first day of the period under audit to the Escrow Commencement Date over (ii) the amount which would have been so paid had the Applicable Percentage of Indian Coal Production Tax Credits determined in the Tax Audit to have been allowable to the Members (or which were not addressed in the Tax Audit) during such period been allocated to Investor. The Applicable Percentage with respect to Indian Coal Production Tax Credits shall be the Investor’s allocable percentage of such Indian Coal Production Tax Credits

under the Operating Agreement. Second, the parties shall determine the excess, if any, of (i) the Deferred Payments paid to the IRS Audit Escrow Account over (ii) 90% of the Indian Coal Production Tax Credits actually allowed to the Investor for the Escrow Period. The sum of the excesses determined in the preceding two sentences shall be the Audit Overpayment. The Escrowed Funds, including interest thereon, shall be paid to Investor in an amount that does not exceed the Audit Overpayment, and any balance shall be paid to WRI. If there remains any balance of the Audit Overpayment after payment of the Escrowed Funds to Investor as provided in the preceding sentence, Investor shall make no further Deferred Payments until the amount of such cancelled Deferred Payments equals such remaining balance of the Audit Overpayment. Further, if there remains any balance of the Audit Overpayment after application of amounts as provided in the preceding two sentences on January 1, 2013, or, at the Conclusion of a Tax Audit, if later, WRI shall pay to Investor such remaining balance. Any payment by WRI to Investor may, at the election of WRI, be paid by means of a promissory note having the characteristics of the Tax Payment Note. Subject to the foregoing, the Deferred Payment Notes, any unexercised Investor Options, the Investor Parent Guaranty, the Investor Pledge and any unexercised Coal Options will remain in full force and effect.

(iv) If at the Conclusion of a Tax Audit, the Indian Coal Production Tax Credit is allowed and the allocations to Investor thereof are allowed, (a) the Escrowed Funds, including the accrued interest thereon, shall be paid to WRI, and (b) the Deferred Payment Notes, Investor Parent Guaranty and the Investor Pledge, the Investor Options and the Coal Options shall remain in full force and effect.

(v) The remedies set forth in this Section 12 shall be the exclusive remedy of Investor for the occurrence of a full or partial Disqualification Event or Disallowance Event, and no separate claim may be made for breach of the representations and warranties in Section 11.18.

12.4 Change in Law. If a Change in Law (as defined in the Restated Operating Agreement) occurs that retroactively reduces or eliminates the Indian Coal Production Tax Credits that are available to Absaloka from the Sublease, such Change in Law shall be treated as a Disqualification Event pursuant to Section 12.3(c)(i) (in the case of an elimination of the Indian Coal Production Tax Credit) and (iii) above (in the case of a reduction of the Indian Coal Production Tax Credit). The remedies set forth in this Section 12.4 shall be the exclusive remedies of Investor for the occurrence of a Change in Law.

12.5 Tax Audit. WRI Sub shall control any and all negotiated settlements with any tax authority with respect to the qualification of coal production from the Absaloka Mine for Indian Coal Production Tax Credits. Investor shall control any and all negotiated settlements with any tax authority with respect to the allocation of Indian Coal Production Tax Credits among the members of Absaloka. The party controlling a negotiated settlement with any tax authority shall, in good faith, consult with the other party regarding the suggested terms of such settlement; provided, however, that the controlling party shall be under no obligation to comply with any suggestion of the other party. The controlling party shall provide to the other party copies of all correspondence or pleadings between the controlling party and the tax authority regarding any tax audit. The other party shall be entitled to monitor all hearings and meetings with the tax authority associated with such settlement negotiations.

14.1 Reports. Absaloka shall be responsible for performing all accounting and reporting with respect to the Contingent Payment Obligation. Beginning with the calendar quarter ending on December 31, 2008, and every applicable calendar quarter thereafter, Absaloka shall prepare and furnish to WRI and Investor within fifteen (15) days after the end of each calendar quarter a Quarterly Report. The “Quarterly Report” shall be a report detailing Indian Coal production and sales from the Sublease for the most recent calendar quarter.

respect to any Contingent Payment Obligation, including by reason of correction in the information provided in the Quarterly Report, but excluding any overpayment occurring by reason of the matters dealt with in Section 12 above, WRI shall return any such overpayment, limited to amounts actually paid to WRI by Investor, after Investor notifies WRI of the amount of such overpayment and provides WRI reasonably satisfactory documentation thereof. Alternatively, without limiting Investor’s recourse under the preceding sentence, Investor may elect to offset the amount of any such overpayment against future payments to WRI under the Contingent Payment Obligation. Likewise, if Investor is determined to have paid WRI less than the amount then due with respect to any Contingent Payment Obligation, Investor shall, upon notice from WRI and delivery of reasonably satisfactory documentation, pay such additional amount to WRI. Investor and WRI agree that, if the overpayment or underpayment has been paid into either the Approval Escrow or the IRS Audit Escrow Account, they will provide joint instructions to the escrow agent to implement the agreements in this Section 14.2. If at any time Investor is determined, other than as described in Section 12, to have paid WRI any amount which could have been deferred pursuant to the Fixed Payment Note, with respect to any Fixed Payment Obligation, by reason of correction in the information provided in the Quarterly Report, but excluding any overpayment occurring by reason of the matters dealt with in Section 12 above, Investor shall be entitled to offset such amount against future payments due under the Fixed Payment Obligation.

14.3 Sales to Unrelated Persons. All sales by Absaloka of Indian Coal mined from the Sublease pursuant to coal sales contracts that have been or will be assigned to Absaloka or that may be entered into in the future regarding sales of Indian Coal which is produced from

14.4 Duration of Sublease. WRI covenants to Investor that the Sublease will remain in effect until September 30, 2013 other than as a result of the failure of a Second Payment Condition; provided, however, that the sole remedy of Investor in the event of breach of this covenant will be to require a Breach Liquidation of Absaloka.

14.5 Assignment of Coal Sales Agreements. WRI shall use commercially reasonable efforts to obtain the assignment to Absaloka of any contracts for the sale of coal produced from the Sublease that have not been previously assigned to Absaloka. WRI shall agree with or stipulate to the customer under any such assigned coal supply agreement that WRI shall remain responsible to the customer in the event Absaloka fails to perform under the coal supply agreement.

14.6 No Cancellation of 2004 Exploration Agreement. WRI agrees that it will not invoke any right it may have under Section 21.3 of the 2004 Exploration Agreement to cancel the 2004 Exploration Agreement by reason of the failure to have obtained approval by the Secretary of Interior by the date specified in such Section.

14.7 Extension of Credit. If the expiration date for the Indian Coal Production Tax Credit is extended, or if such Credit is made permanent, Investor, Absaloka, WRI Sub and WRI agree to negotiate in good faith for an extension of, amendment to, or modification of the transactions contemplated by this Agreement, and WRI agrees not to approach any alternative investor with respect to such a transaction, before the earliest to occur of (a) the conclusion of good faith negotiations with Investor (which conclusion shall be deemed to have occurred in any

WRI and WRI Sub shall also pay one-half of all liability for all transfer taxes, costs, assessments, fines and penalties, and “bulk sales act” or similar assessments, fines and penalties, if any, resulting from the transfer of the WRI Membership Interest and the Investor Options to Investor.

16. Indemnification. For the purposes of this Agreement, “Losses” shall mean any actual loss, cost and expense (including reasonable fees and expenses of attorneys, technical experts and expert witnesses), liability, and damage (including those arising out of demands,

suits, or sanctions of every kind and character); provided, however, that in no event shall “Losses” be deemed to include (a) consequential damages, such as lost profits, lost value of Indian Coal Production Tax Credits (for which the sole remedy is set forth in Section 12) or lost business opportunities, (b) punitive damages, or (c) liabilities or damages to the extent covered by insurance or indemnification or contribution obligations from any other Person which are actually paid over to the Indemnified Party. To the extent this Agreement or the Restated Operating Agreement sets forth a limitation on damages for breach of a representation or warranty or otherwise, “Losses” shall not include any damages in excess of such limitation, and no claim may be made under this Section 16 for any such additional damages.

16.1 Investor’s Indemnification of WRI. Investor shall indemnify, defend and hold harmless WRI and WRI Sub, their officers, directors, shareholders, employees, representatives, agents, successors and assigns, from and against all Losses, and statutory interest thereon, which arise from or in connection with (i) the Post-Acquisition Liabilities, and (ii) Investor’s breach of its representations, warranties and covenants in this Agreement.

16.2 WRI’s Indemnification of Investor. WRI shall indemnify, defend and hold harmless Investor, its officers, directors, shareholders, employees, representatives, agents, successors and assigns, from and against all Losses, and statutory interest thereon, which arise from or in connection with (i) the Pre-Acquisition Liabilities, (ii) WRI’s, WRI Sub’s, or Absaloka’s breach of its respective representations, warranties and covenants in this Agreement or the Restated Operating Agreement and (iii) any liabilities to which Investor may become subject under the borrowing agreements between WRI and First Interstate Bank or any other lender to WRI.

16.3 Procedure for Indemnification. If a complaint, claim or legal action, other than tax audits for which the exclusive remedy is set forth in Section 12 above, is brought or made by a third party (“Third Party Claim”) as to which WRI or Investor is entitled to indemnification hereunder (“Indemnified Party”), the Indemnified Party shall give written notice of such Third Party Claim to the indemnifying party (“Indemnifying Party”) promptly after the Indemnified Party receives notice thereof, which notice shall include a copy of any letter, complaint or similar writing received by the Indemnified Party; provided, however, that any failure to provide, or delay in providing, such notification shall not constitute a bar or defense to indemnification except to the extent the substantive rights of Indemnifying Party have been prejudiced thereby.

The Indemnifying Party shall have the right to assume the defense of such Third Party Claim with counsel reasonably satisfactory to the Indemnified Party. After notice from the Indemnifying Party to the Indemnified Party of the Indemnifying Party’s election so to assume the defense of such Third Party Claim, the Indemnifying Party shall not be liable to the Indemnified Party for any legal or other expenses subsequently incurred by the Indemnified Party in connection with the defense of such Third Party Claim except as hereinafter provided. If the Indemnifying Party elects to assume such defense and selects such counsel, the Indemnified Party may participate in such defense through its own separate counsel, but the fees and expenses of such counsel shall be borne by the Indemnified Party unless (i) specifically agreed in writing by the Indemnifying Party, or (ii) counsel selected by the Indemnifying Party determines that, because of a conflict of interest between the Indemnifying Party and the Indemnified Party, counsel for the Indemnifying Party cannot adequately represent both parties

in conducting the defense of such action (in which case the Indemnifying Party shall not have the right to direct the defense of such Third Party Claim on behalf of the Indemnified Party).

The failure of the Indemnifying Party to notify an Indemnified Party of its election to defend such Third Party Claim within twenty-one (21) days after notice thereof was given to the Indemnifying Party shall be deemed a waiver by the Indemnifying Party of its rights to defend such Third Party Claim.

If the Indemnifying Party assumes the defense of such Third Party Claim, the obligations of the Indemnifying Party shall include taking all steps reasonably necessary in the defense of such Third Party Claim and holding the Indemnified Party harmless from and against any and all damages caused by or arising out of any settlement or any judgment in connection with such claim or litigation. The Indemnifying Party may not settle such Third Party Claim without the consent of the Indemnified Party, which consent shall not be unreasonably withheld, unless such settlement involves solely the payment of money and the giving of customary releases which will not disadvantage the Indemnified Party in any manner.

If the Indemnifying Party does not assume the defense of such Third Party Claim in accordance with this Section 16.3, the Indemnified Party may defend against such claim or litigation in such manner as it deems appropriate; provided, however, that the Indemnified Party may not settle such Third Party Claim without the prior written consent of the Indemnifying Party, which consent shall not be unreasonably withheld. The Indemnifying Party shall promptly reimburse the Indemnified Party for the amount of such settlement, or for the amount of any judgment rendered with respect to such Third Party Claim, and for all reasonable costs and expenses incurred by the Indemnified Party in the defense of such claim, subject to the limitations on liability set forth herein.

16.4 Maximum Indemnification Liability. The parties intend that any recovery under this Section 16 shall be without duplication of any recovery under the Restated Operating Agreement or any other source for the same claim, and that:

(a) Except for liabilities arising out of breach of the representation and warranty in Section 11.15 relating to environmental matters, the aggregate indemnification liability of WRI and its Affiliates including, without limitation, WRI Sub, to Investor under Section 16.2 above shall not exceed the aggregate Equity Payment, Deferred Payments and all Option Purchase Prices paid by Investor to WRI and WRI Sub pursuant to this Agreement, as of the date the claim giving rise to such liability is made.

(b) If Investor is liable under this Section 16 to indemnify WRI, the aggregate indemnification liability of Investor shall not exceed the aggregate amount which is actually accrued and due from Investor to WRI pursuant to this Agreement as of the date the claim giving rise to such liability is made.

16.5 After-Tax Basis. For purposes of this Agreement, no damages shall be deemed to have been suffered by a party hereto with respect to any matter for which indemnification is sought to the extent that such party or its direct or indirect equity owner realizes any tax benefit relating thereto or arising therefrom. All indemnification payments made pursuant to this Section 16 shall be calculated and paid on an after-tax basis taking into account any state and federal income taxes imposed on any indemnification payments made pursuant to this Section 16, and taking into account all reimbursements, including insurance.

17. Xxxxxxxxxxxx Coal Company Guarantee. WCC hereby agrees that it will be responsible for the prompt payment by WRI of all of its obligations hereunder and under the Restated Operating Agreement in accordance with the terms hereof and thereof, as such

agreements may be amended from time to time, and that upon default by WRI in such obligations, Investor may pursue remedies directly against WCC without the necessity of first pursuing and exhausting remedies against WRI.

18. Miscellaneous.

18.1 Further Assurances. WRI, WRI Sub, Investor and Absaloka shall execute, acknowledge and deliver or cause to be executed, acknowledged and delivered such instruments and take such other action as may be reasonably necessary or advisable to carry out the purposes and intents of this Agreement and any document, certificate or other instrument delivered pursuant hereto.
