To the knowledge of Seller (i) there are no outstanding directives or orders from any sanitation, health, fire, law enforcement or safety authorities or from any other Government Authority applicable to the Owned Real Property and  (ii) there are no pending or threatened condemnation, eminent domain or similar proceedings or special assessments affecting the Owned Real Property, nor has Seller received written notification that any such proceeding or assessment is contemplated.

5.3                               Representations and Warranties of Buyer.  Buyer represents and warrants to Seller as of the Closing Date as follows.

(a)                                 Due Incorporation.  Buyer is a limited liability company duly organized, validly existing and in good standing under the Laws of the State of its formation.  Buyer has all requisite power and authority to own, lease and operate its properties and to carry on its businesses as now being conducted.  Buyer is in good standing, and is authorized to transact

15

business in those states where such qualification is necessary to conduct business as a foreign corporation.

(b)                                 Non-Contravention.  The execution, delivery and performance by Buyer of the Transaction Documents to which it is a party, and the consummation by Buyer of the Transactions, does not conflict with, or result in any violation of or default (with or without notice or lapse of time, or both) under, or gives rise to a right of termination, cancellation or acceleration of any obligation or to loss of a material benefit under any provision of (i) the organizational documents of Buyer, (ii) any contract or agreement to which Buyer is a party, or (iii) any judgment, order or decree or Law applicable to Buyer, other than such violation as would not reasonably be expected to materially affect Buyer’s ability to perform its obligations under the Transaction Documents to which it is a party.

(c)                                  Consents.  No consent, approval, license, permit, order or authorization of, or registration, declaration or filing with, any Government Authority is required to be obtained or made by or with respect to Buyer in connection with the execution, delivery and performance of the Transaction Documents, other than (x) those that may be required solely by reason of Seller’ (as opposed to any other third party’s) participation in the Transactions, and (y) those that, if not obtained or made by each such entity, would not be reasonably likely to have a material adverse effect on the Transactions.

(d)                                 Due Authorization and Enforceability.  Buyer has full power and authority to enter into the Transaction Documents to which it is a party and to consummate the Transactions.  The execution, delivery and performance of the Transaction Documents to which it is a party have been duly and validly approved and no other corporate proceedings on the part of Buyer are necessary to authorize the Transaction Documents to which it is a party or the Transactions.  The Transaction Documents to which the Buyer is a party have been duly and validly executed and delivered by Buyer and are enforceable against Buyer in accordance with their respective terms, except as such enforceability may be limited by applicable bankruptcy, insolvency, moratorium, reorganization or similar laws from time to time in effect which affect creditors’ rights generally and by legal and equitable limitations on the availability of specific remedies.

(e)                                  Litigation.  There are no actions, proceedings or investigations by or before any Government Authority pending or, to the knowledge of Buyer, threatened against Buyer or any of its Affiliates which in any manner challenge or seek to prevent, enjoin, invalidate, or materially restrain the Transactions.

(f)                                   No Brokers.  Buyer has not incurred any liability, contingent or otherwise, for brokers’ or finders’ fees relating to the Transactions for which Seller or any of its Affiliates would be liable.

(g)                                  Financial Assurance.  Buyer has evaluated the bonds and other security requirements described in Schedule 3 attached to this Agreement and has the financial capability to furnish or cause to be furnished the replacement security described in Section 6.3.

(h)                                 Experienced Investor.  Buyer and its Affiliates have been engaged in the mining and natural resources businesses relevant to the assets transferred pursuant to the Transaction

16

Documents.  Buyer and its Affiliates are experienced with the operations and ownership obligations for assets such as the Transferred Properties. Buyer represents that it is a sophisticated party, and has conducted a full due diligence investigation of the Transferred Properties.  Prior to entering into this Agreement, Buyer was advised by its own legal, tax and other professional counsel concerning this Agreement and the Transferred Properties.  Buyer is aware of the risks and uncertainties of an investment in the assets transferred pursuant to the Transaction Documents and is able to absorb a loss of its investment.

5.4                               Real Property Title Matters.  Buyer has conducted such title examination of the Real Property that it deems appropriate and acknowledges that Seller makes no warranty of title to the Real Property other than those representations and warranties set forth in Sections 5.2(f), 5.2(h), 5.2(i) and 5.2(j) hereto, and is selling only such interest or interests, if any, as it may own in the Real Property.

5.5                               Exclusivity of Warranties and Specific Disclaimers.  Buyer acknowledges that it is acquiring the Transferred Properties on the basis of its own investigation of the physical condition of the Transferred Properties and assumes the risk that adverse conditions outside the scope of Seller’s representations and warranties set forth in Sections 5.1 and 5.2 may not be revealed by Buyer’s own investigation.  Buyer has made its own estimate of prospective data such as future revenues, operating costs, and liabilities based on Buyer’s own abilities and skills to operate these properties, and is not relying on Seller’s own estimates of such data. Buyer acknowledges that, EXCEPT AS EXPRESSLY PROVIDED IN THE TRANSACTION DOCUMENTS, (i) THE TRANSFERRED PROPERTIES ARE SOLD “AS IS” AND “WITH ALL FAULTS,” (ii) NO WARRANTY, EXPRESS OR IMPLIED IN FACT OR BY LAW, WHETHER OF MERCHANTABILITY, FITNESS FOR ANY PARTICULAR PURPOSE, CONDITION OR OTHERWISE, CONCERNING THE TRANSFERRED PROPERTIES HAS BEEN MADE TO BUYER AND (iii) BUYER’S REMEDIES AGAINST SELLER AND ANY OF ITS AFFILIATES, AND THE LIABILITIES OF SELLER AND ANY OF ITS AFFILIATES TO BUYER WITH RESPECT TO THE CONDITION OF THE TRANSFERRED PROPERTIES ARE LIMITED TO THOSE PROVIDED IN ARTICLE 8 OF THIS AGREEMENT.

ARTICLE 6

ADDITIONAL COVENANTS

6.1                               Announcements.  Except for disclosures that Seller or Buyer reasonably believe are required by Law or any securities exchange to which Seller or Buyer may be subject, no Party shall issue any press release or otherwise make any public announcement with respect to the Transactions without the prior written consent of the other Parties, which consent shall not be unreasonably withheld or delayed.

6.2                               Transfer Requirements.

(a)                                 Transfer of Lease Agreements and Applicable Contracts.  Neither this Agreement nor any Ancillary Agreement shall constitute an assignment or an attempted assignment of any Applicable Contract to the extent that such assignment or attempted assignment would constitute

17

a breach of such Applicable Contract.  To the extent any of the Applicable Contracts are not transferred and assigned on the Closing Date due to delays in procuring required notices, consents or actions from or by any Government Authority or third party, then such Applicable Contract shall not be assigned and transferred until and unless the proper notice, consent or action requirement shall have been satisfied.  The Parties shall use their commercially reasonable efforts, each as to matters within its control, to satisfy such requirements as soon as reasonably practicable and agree to cooperate with each other in any reasonable arrangement designed to provide Buyer with the benefits of such Applicable Contracts.

(b)                                 Costs of Transfer.  Each of Buyer and Seller shall bear its own costs and expenses incurred in connection with the transfer, amendment, reissuance or issuance of the Applicable Contracts.  Buyer, at its sole expense, shall provide bonds, letters of credit, guarantees or other security or support as may be required by Law or any Government Authorities for the transfer or reissuance of any Permits or Applicable Contracts to Buyer.

6.3                               Transfer of Permits and Security.

(a)                                 Permits and Transition Permits. Each of Buyer and Seller shall, with the reasonable assistance of the other, as required, coordinate with each applicable Government Authority to pre-approve, prior to closing, the transfer to Buyer (and documentation associated with such transfer) of each Permit applicable to the Transferred Properties, or to have such Permit approved for re-issuance.  If for any reason any Permit applicable to the Transferred Properties has not been transferred to Buyer or reissued, as applicable, as of the Closing Date, then the Seller or its Affiliates shall, to the extent allowed by applicable Law, maintain each such Permit (each a “Transition Permit”) in full force and effect until the earlier of the transfer or the reissuance of such Permit and shall, if requested by Buyer, allow Buyer to use and operate under each such Transition Permit during such period.  Seller or its Affiliates shall maintain any related bond, letter of credit, guarantee or other security or support required by Law or any Government Authority for each such Transition Permit (the “Transition Bonds”) until the transfer or reissuance of such Transition Permit.  Buyer agrees to reimburse the Seller for bond premiums, fee payments and other direct costs incurred by Seller or its Affiliates in connection with the maintenance of the Transition Permits and the Transition Bonds from the Closing Date up to the date that the transfer or reissuance of the Transition Permit occurs and the Transition Bond related thereto is released.  Each of Buyer and Seller shall use commercially reasonable efforts to cause the transfer or reissuance of all the Transition Permits to occur prior to December 31, 2012 and Seller and its Affiliates shall continue to cooperate with Buyer and each use its commercially reasonable efforts to cause the Transition Permits to be transferred to or reissued.  Buyer shall furnish any bonds or other security required in connection with the transfer or reissuance of all such Transition Permits, as promptly as requested by Seller and, if sooner, when required pursuant to applicable Law.  If, after the Closing Date, a consent or other requirement to the transfer or reissuance of any Transition Permit is required, then Seller and its Affiliates shall continue to cooperate with Buyer and each use their respective commercially reasonable efforts to cause the Transition Permits to be transferred to or reissued for no additional consideration payable to Seller.

(b)                                 Transition Permit Violations.  If Seller or its Affiliates receive a notice of violation under any Transition Permit following the Closing Date but before the transfer or

18

reissuance of such Transition Permit, which is based on or arises out of the activities or operations of Buyer after the Closing Date, the Seller will promptly notify Buyer, and Buyer shall be responsible for curing such violation and any obligation or liability associated therewith and shall indemnify Seller and its Affiliates as provided in Section 8.2.  If the Seller determines, in its reasonable discretion, that Buyer will not cause such violation to be cured in the time period required by applicable Law, then Seller shall have the right to cure such violation at Buyer’s expense after first providing Buyer with written notice of the Seller’s intent to cure and a reasonable opportunity to either cure the violation or contest the violation.

6.4                               Government Authority Reviews and Approvals.

(a)                                 Government Reviews and Approvals.  If any Government Authority demands a filing or other information, Seller, Buyer and their respective Affiliates shall cooperate and promptly undertake all filings and other actions as may be required to comply with any review or approval requirements.  Should the reviewing agency advise any Party of its need for additional information, that Party, with the cooperation of the other Parties if appropriate, shall promptly respond to the reviewing agency’s request.  Should the reviewing agency or another interested Government Authority advise any party of its opposition to the Transactions, the Parties shall use commercially reasonable efforts to persuade the agency concerned to abandon its opposition and, failing to do so, the Parties shall take such additional actions as agreed between the Parties. Notwithstanding anything to the contrary contained in any Transaction Document, nothing in this Agreement shall require Buyer to take any action not otherwise required by this Section 6.4, including but not limited to (i) disposing or transferring any asset, (ii) holding separate any assets or operations, or (iii) changing or modifying any course of conduct or otherwise making any commitment (to any Government Authority or otherwise) regarding the future operations of the Buyer’s business or the Transferred Properties to obtain any approval from any Government Authority, to prevent the initiation of any lawsuit by any Government Authority, or to prevent the entry of any decree, judgment, injunction preliminary or permanent, or any other order that would make the Transactions unlawful.  Furthermore, Buyer shall not be obligated to defend, contest, or resist any action or proceeding (beyond the investigation cooperation obligations in this Section 6.4) instituted (or threatened to be instituted) challenging the Transactions as violative of any Law.

(b)                                 Ownership Change Filings.  Each of Buyer and Seller shall promptly and diligently make all necessary filings and satisfy all necessary requirements with appropriate Government Authorities in order to transfer ownership of the Transferred Properties from the Seller to Buyer.

6.5                               Termination of Rights to Seller’s Insurance.

(a)                                 Each of the Parties acknowledge that Seller and its Affiliates have maintained worldwide programs of property and liability insurance coverage for itself and its Affiliates, including with respect to the Transferred Properties, and insurance policies that are written or reinsured by Affiliates or that require the payment of retrospective premium adjustments to cover losses.  All of the insurance policies through which such worldwide programs of coverage are presently or have previously been provided (including all employers’ liability insurance policies) are hereafter called “Seller Policies.”

19

(b)                                 It is the understanding and intention of Seller and Buyer that:

(i)                                     from and after the Closing Date, no insurance coverage shall be provided for Buyer under any Seller Policy relating to the Transferred Properties; and

(ii)                                  from and after the Closing Date, no claims regarding any matter whatsoever, whether or not arising from events occurring prior to, at or after the Closing Date, shall be made against or with respect to any Seller Policy by Buyer.

(c)                                  Buyer, on behalf of itself and its successors and assigns, hereby releases, to the extent permitted by applicable Law, Seller and its Affiliates from liability relating to any claim made by or through Buyer after the Closing Date against or with respect to any Seller Policy.

(d)                                 Nothing contained in the foregoing provision of this Section 6.5 shall in any way limit, impair or constitute a release or discharge of any right of Buyer or obligation of Seller or its Affiliates with respect to any representation, warranty, covenant, agreement, indemnity or other obligation contained in any Transaction Document (regardless of whether the same was, is or may be covered by any insurance policy described herein), all of which rights and obligations shall continue in full force and effect.

6.6                               Removal of Proprietary Information.  Except as provided in any third party license included in the Transferred Properties, Seller may remove all proprietary information in tangible or intangible form that is (i) owned by a third party (or is not in use or has not been in use within one (1) year prior to the Closing Date) concerning the Transferred Properties, (ii) proprietary to Seller or its Affiliates, or (iii) otherwise excluded from the Transferred Properties pursuant to Section 2.2.

6.7                               Replacement of Seller Identification.  Buyer shall, at its own expense and in a timely manner not exceeding thirty (30) calendar days after the Closing Date, remove or cause to be removed all signs and placards which identify Seller, or any of its Affiliates, as a prior owner of any of the Transferred Properties, including any usage of trademarks or trade names of Seller and its Affiliates.  Buyer shall, at its own expense and in a timely manner not to exceed one week after the Closing Date, erect or install signs and placards as may be required by state or other governmental agencies identifying Buyer as the owner and/or operator of each of the Transferred Properties.

6.8                               Seller Records.  Within 30 days of Closing Seller shall deliver to Buyer copies of all Seller Records.

ARTICLE 7

TAXES

7.1                               Transfer Taxes.  Notwithstanding Section 7.2(a), any recording fees, transfer Taxes (including but not limited to any sales Tax), use Tax, real property transfer Tax, asset transfer Tax, documentary stamp Tax or similar other charges imposed on the conveyance of the Transferred Properties pursuant to this Agreement by any Government Authority (collectively, “Transfer Taxes”) shall be promptly paid by Buyer in accordance with the Law or Government

20

Authority levying such Tax (or reimbursed to the Seller by Buyer within five (5) Business Days after demand therefor); provided, however, that if Buyer holds a direct payment permit which is valid on the Closing Date, Buyer shall assume all responsibility for remitting to the appropriate taxing authority the sales and use Taxes due for such permit and shall provide the Seller with any exemption certificates or other documentation required under applicable Law in lieu of paying Seller the Taxes due.  Buyer shall indemnify, defend and hold harmless the Seller against any Transfer Taxes assessed against or otherwise incurred by Seller as a result of the transactions contemplated by this Agreement, including the amounts of any penalties, interest, attorney’s fees and any other Losses related thereto.

7.2                               Tax Apportionment.

(a)                                 All property or ad valorem Taxes for the current year, including but not limited to Taxes on real estate, fixtures, personal property and inventory, shall be prorated between Buyer, on the one hand, and the Seller, on the other hand, as provided herein.  The Seller shall be responsible for all such Taxes payable with respect to the Transferred Properties for all taxable periods ending prior to the Closing Date.  Buyer shall be responsible for the payment of all such Taxes payable for all taxable periods beginning on or subsequent to the Closing Date.  As to any taxable period beginning before the Closing Date and ending on or after the Closing Date (a “Straddle Period”), all such Taxes shall be prorated by allocating to the period before the Closing Date the amount of such Taxes for the entire taxable period multiplied by a fraction the numerator of which is the number of calendar days in the taxable period ending on the day immediately prior to the Closing Date and the denominator of which is the number of calendar days in the entire taxable period.  The Seller shall be responsible for any such Taxes payable with respect to the Transferred Properties allocated to the portion of the taxable period ending on the day immediately prior to the Closing Date, and Buyer shall be responsible for any other such Taxes.  If Taxes are prorated and based on an estimate of the current period Taxes, there shall be a final settlement between Buyer and the Seller based on the actual Taxes due for the taxable period.  Any refunds or rebates that may be received with respect to the Taxes referenced in this Section 7.2(a) shall be prorated between Buyer and the Seller in the same manner as described above to prorate Taxes, and the Seller shall be entitled to all refunds and rebates for taxable periods (and portions thereof) ending prior to the Closing Date and the Buyer entitled to all refunds and rebates for taxable periods (and portions thereof) beginning on and after the Closing Date that may be received. Any refunds or rebates will be paid to the applicable Party within thirty (30) days of receiving the refund or rebate.

(b)                                 Severance Tax (and ad valorem Tax based on such severance taxable value), if any, shall be treated as attributable to the period ending on the Closing Date to the extent that the coal which constitutes the base upon which such Tax was levied was severed on or before the Closing Date, sold on or before the Closing Date and the revenue from such sale was accrued or received on or before the Closing Date.  Seller shall be responsible for all such Taxes payable with respect to the Transferred Properties attributable to the period ending on the Closing Date.

(c)                                  In the event that any Party receives a notice of any audit or administrative or judicial or other proceeding involving Taxes, which, if determined adversely, could result in a liability of the other Party or Parties under this Agreement (the Party or Parties receiving such notice of liability will hereafter be referred to as the “liable Party or Parties”), the liable Party or

21

Parties will immediately notify the other Party or Parties (the “responsible Party or Parties”) in writing of such audit or administrative or judicial or other proceeding.  In the case of an audit or administrative or judicial or other proceeding that relates to any taxable period that is not a Straddle Period, the responsible Party or Parties after receiving notice shall have the option of either:

(i)                                     Paying the Tax directly, including payment under protest to preserve the right to contest the liability, or

(ii)                                  Challenging the proceeding referred to in such notice.  The responsible Party or Parties shall take all action necessary and shall have the right (solely or jointly, as the case may be) to control any audits, disputes, administrative, judicial, or other proceedings and incidents to such challenge and to employ counsel of its respective choice therein.  If the responsible Party or Parties elect to challenge the validity of such bill, invoice, notice of deficiency or similar communication or any portion thereof, the liable Party or Parties shall extend reasonable cooperation to the responsible Party or Parties in such efforts at no expense to the responsible Party or Parties.

Notwithstanding the foregoing, the liable Party or Parties may (solely or jointly, as the case may be) elect to pay such notice of liability; however, the responsible Party or Parties will not have to reimburse such payment unless the responsible Party or Parties have consented to that payment and reimbursement and the responsible Party’s or Parties’ right to contest such liability is preserved.  If a notice of liability may affect the liability or obligations of both a liable Party and another Party, the liable Party or Parties shall keep the other Party or Parties reasonably informed of the progress of any challenge of the liability asserted in such notice and the other Party’s or Parties’ consent shall be required prior to the settlement of any such notice, which consent shall not be unreasonably withheld, conditioned or delayed.

If the notice of an audit, or administrative, judicial or other proceeding relating to Taxes relates to a Straddle Period the liable Party or Parties and responsible Party or Parties shall be entitled to jointly challenge the proceeding referenced in the notice.  The liable Party or Parties and responsible Party or Parties shall control any audits, disputes, administrative, judicial or other proceedings and incidents to such challenge and to employ counsel of their choice.  The Parties shall not consent to the settlement of such proceeding without each liable and responsible Party’s written consent, which consent shall not be unreasonably withheld, conditioned, or delayed.

7.3                               Refunds.  Other than Taxes covered in Section 7.2(a), the Seller shall be entitled to any refund of Taxes paid by Seller, in each case to any Government Authority for taxable periods (or portions thereof) ending prior to the Closing Date.  Buyer shall be entitled to any refund of taxes paid by Buyer to any Government Authority for taxable periods (or portions thereof) beginning on or after the Closing Date.  The Party receiving a refund shall make a good faith effort to ascertain the source of the refund and to resolve by mutual consent the ownership of any refunds related to the subject properties.

7.4                               Cooperation.  Subject to the reimbursement of reasonable out-of-pocket expenses, the Parties will provide to each other such records and assistance as may be reasonably requested by any of them in connection with the preparation of any Tax Return, and audit or other

22

examination by any Government Authority, and any judicial and administrative proceedings related to the liability for Taxes (including any additions to or refund of taxes) involving the Transferred Properties.  The Parties shall also make employees available on a mutually convenient basis to provide additional information and explanation of any material provided hereunder.  Seller and Buyer shall retain all books and records with respect to Tax matters pertinent to Transferred Properties relating to any taxable period beginning before the Closing Date until expiration of the statute of limitations (and any extensions thereof) of the respective taxable periods, and to abide by all record retention agreements entered into with any Government Authority.

7.5                               Tax Returns.

(a)                                 Seller shall prepare or cause to be prepared all Tax Returns for the Transferred Properties, for all taxable periods ending on or prior to the Closing Date which are filed after the Closing Date.

(b)                                 Buyer shall prepare or cause to be prepared and file or cause to be filed all Tax Returns with respect to the Transferred Properties, other than the Tax Returns which Seller shall prepare, or cause to be prepared, pursuant to Section 7.5(a), which are due after the Closing Date.  If any such Tax Return relates to any period beginning before the Closing Date, and is a Tax Return where the Seller may have responsibility hereunder for the Taxes reported thereon, Buyer shall permit Seller to review and comment on the proposed Tax Return no later than thirty (30) days prior to the filing date of such Tax Return (including extensions thereof) and shall consider applying all reasonable comments of Seller, at Buyer’s discretion, related to such Tax Returns. Tax Returns described in the preceding sentence shall be prepared consistently with the past practice of the Seller, unless otherwise required by Law.

(c)                                  Buyer shall not, nor shall it permit any Affiliate of Buyer to, amend, refile, make or otherwise modify, any Tax election or Tax Return with respect to any Transferred Properties for any taxable period ending prior to the Closing Date or any Straddle Period without the prior written consent of the Seller, which consent shall not be unreasonably withheld, conditioned or delayed.  Seller shall not, nor shall it permit any Affiliate of Seller to, amend, refile, make or otherwise modify, any Tax election or Tax Return with respect to any Transferred Properties for any taxable period ending prior to the Closing Date or any Straddle Period where such amendment, refilling, modification or otherwise could potentially have an adverse affect on Buyer without the prior written consent of Buyer, which consent shall not be unreasonably withheld, conditioned or delayed.

8.2          Losses Indemnified and Assumed by Buyer.

(a)           Breaches of Representations and Warranties.  Buyer shall indemnify, defend and hold harmless Seller and its Affiliates (including their respective directors, officers, partners, managers, members, investors, employees, agents and representatives) against any Losses attributable to a breach of Buyer’s representations and warranties under any Transaction Document provided that (i) the liability of Buyer for Losses for any claim made pursuant to this Section 8.2(a) must exceed, in the aggregate, a deductible of one and one-half percent (1.5%) of the Purchase Price after which Buyer shall be responsible for all such Losses from the first dollar (and not simply the amount in excess of such deductible) and (ii) the cumulative liability for Buyer for all Losses for all claims made pursuant to this Section 8.2(a) shall not exceed Two Million Five Hundred Forty Two Thousand Three Hundred Seventy Three Dollars ($2,542,373.00).

(b)           Breaches of Covenants and Obligations. Buyer shall indemnify, defend and hold harmless Seller and its Affiliates (including their respective directors, officers, partners, managers, members, investors, employees, agents and representatives), from and after the Closing Date, against any Losses attributable to a breach of, or default in, the performance by Buyer of any covenant, agreement or obligation to be performed by Buyer pursuant to any Transaction Document.

(c)           Assumption of Liabilities and Obligations.  In addition to the foregoing indemnity, Buyer hereby contractually assumes all Losses, liabilities and obligations relating to the Transferred Properties not specifically retained by the Seller, including Reclamation liabilities and obligations pursuant to the terms of the agreements contained in the conveyancing instruments included in Exhibit A and Exhibit B attached to this Agreement or pursuant to the

24

instruments required by the applicable Government Authorities for release and substitution of Seller security assurances as described in Section 6.3.  However, Buyer does not assume any Losses, liabilities or obligations, and Seller shall remain liable with respect to (i) any Losses arising out of a breach by Seller or its Affiliates of the terms or conditions of any Transaction Document or (ii) any Losses related to Excluded Items.

8.3          Indemnification, Defense and Communication Procedures.  Upon any Indemnitee becoming aware of anything which is or may give rise to a claim for indemnification or grounds for making a claim under this Article 8 or of any other claim, action or demand or matter likely to give rise to a claim for indemnification under this Agreement, the Indemnitee shall:

(a)           notify the Indemnitor by written notice as soon as reasonably practicable after it appears to the Indemnitee that any assessment or claim, action or demand of a third party received by or coming to the notice of the Indemnitee may result in a claim under this Article 8 or elsewhere in this Agreement, specifying all material details as are then available to the Indemnitee (provided, however, that an Indemnitee’s failure to notify does not release, reduce or otherwise affect the Indemnitor’s duty to indemnify, except to the extent of any actual prejudice suffered by the Indemnitor as a result of such failure to notify);

(b)           take such action and give such information and access to personnel, premises, property, documents and records to the Indemnitor and its professional advisers as the Indemnitor may reasonably request and the Indemnitor shall be entitled to require the Indemnitee to take such action and give such information and assistance in order to avoid, dispute, resist, mitigate, settle, compromise, defend or appeal any claim in respect thereof or adjudication with respect thereto, subject to the Indemnitor indemnifying the Indemnitee against all reasonable costs and expenses incurred by the Indemnitee in complying with any such request or requirement;

(c)           at the request of the Indemnitor and other than with respect to any action seeking specific performance or other equitable remedies, allow the Indemnitor to assume the defense of such actions, make any decision to arbitrate or settle any such action, and otherwise undertake the sole conduct of such actions as the Indemnitor may deem appropriate in connection with any such assessment or claim in the name of the Indemnitee, and in that connection the Indemnitee shall give or cause to be given to the Indemnitor all such assistance as the Indemnitor may reasonably require in avoiding, disputing, resisting, settling, compromising, defending or appealing any such claim and shall instruct such attorneys or other professional advisors as the Indemnitor may nominate to act on behalf of the Indemnitee, as appropriate, but to act in accordance with the Indemnitor’s sole instructions, subject to the Indemnitor’s indemnifying the Indemnitee against all costs and expenses incurred by the Indemnitee in complying with any such requirement; and

(d)           make no admission of liability, agreement, settlement or compromise with any third party in relation to any such claim or adjudication without the prior written consent of the Indemnitor (such consent not to be unreasonably withheld, conditioned or delayed).

25

In the event that a claim is within the scope of the indemnities of two or more Indemnitors, each Indemnitor shall be responsible for the indemnity and defense and shall bear the costs of indemnity and defense to the extent of and in proportion to the coverage of its indemnity.

8.4          No Liability if Loss is Otherwise Compensated For.

(a)           No Indemnitee shall be entitled to recover damages or otherwise obtain reimbursement or restitution more than once in respect of the same loss or damage.

(b)           No Indemnitor shall be liable for any claim to the extent the Indemnitee has a claim, right of indemnification or right of set off against any third party (other than in connection with an insurance claim pursuant to clause (d) below and net of any expenses in obtaining such third party payment), unless the Indemnitee assigns such claim, right of indemnification or right of set off against such third party to the Indemnitor.

(c)           Any payment made by an Indemnitor to an Indemnitee pursuant to this Article in respect of any claim will be reduced by an amount equal to any reduction in Taxes realized by the Indemnitee that are attributable to such claim, taking into account any offsetting increases in Taxes associated therewith.

(d)           If any matters giving rise to a claim of indemnification by an Indemnitee may be covered by any insurance policy or policies carried by (i) an Indemnitee (other than a self-administered claims program or policies issued or indemnified by an Indemnitee or its Affiliates) or (ii) a party other than the Indemnitees (e.g., a policy carried by a contractor of an Indemnitee that names an Indemnitee as an additional insured), then such Indemnitee shall use commercially reasonable efforts to pursue the claim and obtain compensation from its insurer or insurers under such insurance policy or policies.  If and when such compensation is actually received from such insurers for the matters giving rise to a claim of indemnification, such Indemnitee shall reduce such claim of indemnification against the Indemnitor to the extent of Indemnitee’s insurance recovery (minus expenses incurred in pursuing the claim with its insurer) or, if payment has already been made on such claim of indemnification, then such Indemnitee shall remit the insurance recovery (minus expenses incurred in pursuing the claim with its insurer), to the Indemnitor.

8.5          Survival.  The representations and warranties of Seller in Sections 5.1 and 5.2 and the representations and warranties of Buyer in Section 5.3 shall survive the execution of this Agreement and the consummation of the Transactions, but shall expire eighteen (18) months after the Closing Date, except to the extent that a notice of claim under Article 5, filed in accordance with Section 8.3, shall have been given to the Party obligated thereunder within such eighteen-month period. Notwithstanding the foregoing, the representations and warranties of Seller in Sections 5.1(a), 5.1(d), 5.2(d), 5.2(f), 5.2(h), 5.2(k) and 5.2(n) shall survive the execution of this Agreement and the consummation of the Transactions, but shall expire on the seventh (7th) anniversary of the Closing Date.

8.6          Exclusive Remedy; Exclusive Recourse.  Except for such equitable remedies as may be available to enforce any of the provisions of this Agreement and other than as set forth in Section 8.7 hereof, the indemnifications under this Article or elsewhere in this Agreement are the Parties’

26

sole and exclusive remedies, each against the other, with respect to matters arising solely under this Agreement.  The Parties hereby waive and release any other rights, remedies, causes of action or claims arising under this Agreement.  Buyer agrees that except in cases of fraud or willful misconduct its sole and exclusive recourse for indemnification claims with respect to Seller or its Affiliates shall be against Seller, and hereby agrees to bring any and all claims and disputes hereunder exclusively against Seller.

8.7          Specific Performance.  Each Party acknowledges and agrees that the other Party may be damaged irreparably if any Transaction Document is not performed in accordance with its terms or otherwise is breached and that a Party will be entitled to seek injunctive relief to prevent breaches hereof and thereof and to enforce specifically the Transaction Documents and its terms in addition to any other remedy to which such Party may be entitled hereunder and thereunder.

ARTICLE 9

GENERAL TERMS

9.1          Costs and Expenses.  Buyer shall pay the cost of any title insurance acquired on any of the Transferred Properties.  In addition, Buyer shall pay all filing fees, costs of assignments of Applicable Contracts and Permits and costs of recording required in connection with the Transactions.  Each Party shall pay its own attorneys’ fees and other expenses related to the preparation and execution of the Transaction Documents.

9.2          Bulk Transfer Law.  Buyer waives compliance with the provisions of any applicable bulk sales or bulk transfer Law.  Seller shall indemnify and hold Buyer harmless from any claims, loss or liability incurred by Buyer as a result of the failure to so comply; provided, however, such indemnity shall not apply to obligations and liabilities assumed by Buyer.

9.3          Further Assurances. At the request of either Party, Seller and Buyer will cause to be executed and delivered all such further instruments of conveyance, assignments and further assurances as reasonably may be required to transfer and assign Seller’s interest in the Transferred Properties or otherwise to implement the provisions and intent of this Agreement and the other Transaction Documents.  To the extent that it is determined by mutual agreement of all Parties following the Closing Date that any asset intended hereunder to have been an Excluded Item or otherwise intended not to transfer to the Buyer hereunder was so transferred, the Buyer shall promptly re-transfer such asset to the Seller.

9.4          Notices.  All notices and other communications required or permitted to be given or delivered hereunder shall be in writing and shall be delivered personally, transmitted by facsimile with answerback confirmed or sent by recognized overnight courier service or United States mail, postage prepaid and return receipt requested, directed to the Party intended at the address set forth below, or at such other address as may be designated by such Party by notice given to the other Party in the manner aforesaid, and shall be effective upon receipt:

27

9.5          Assignment.  No Party may assign any right granted to it under this Agreement or delegate performance of any duty to be performed by it hereunder without the express written consent of the other Party, which consent shall not be unreasonably withheld or delayed, provided that the Buyer shall be entitled to (i) assign and pledge its rights and interests under any Transaction Document to any financing party under any existing credit facility of the Buyer or its Affiliates or (ii) assign its rights and interests under any Transaction Document to any Affiliate of the Buyer, provided further that Buyer shall remain obligated to perform any of its duties under this Agreement notwithstanding any such assignment.  Subject to the foregoing, all rights and duties of each Party hereunder shall inure to the benefit of and be binding upon its successors and permitted assigns.

9.6          Governing Law and Dispute Resolution.  The interpretation and enforcement of this Agreement, and any arbitration and arbitral decision pursuant to clause (b) below, shall be governed by the substantive law of the State of New York, without the application of its conflict of law rules; provided, however, questions concerning arbitrability under the dispute resolution provision hereof shall be governed exclusively by the United States Arbitration Act (9 U.S.C. § 1-16) and questions concerning real property or title to real property shall be governed exclusively by the laws of the state in which such real property is located.

(a)           The Parties desire to avoid all forms of traditional litigation and therefore agree, except as otherwise specifically set forth in this Agreement, that all disputes, controversies or claims arising out of or relating to this Agreement (collectively “Disputes”) shall be resolved in accordance with the following procedures:

(i)            The Parties shall use commercially reasonable efforts to resolve Disputes through direct discussions.  Each of Seller and Buyer commits its management to respond promptly to any communications concerning Disputes.

(ii)           If the Parties are unable to resolve any Dispute, than the party asserting the existence of a dispute shall provide to the other Party, a description of the factual or legal basis for the Dispute through a formal written notice.

(iii)          Within fifteen (15) days of written notice that there is a Dispute, representatives of the Parties with authority to settle the matter shall meet at a mutually acceptable time and place in Denver, Colorado or such other location as may be agreed, and as often thereafter as they deem reasonably necessary in an effort to reach an amicable resolution.  If a representative intends to be accompanied at a meeting by an attorney, the other negotiator shall be given at least three (3) Business Days’ notice of such intention and may also be accompanied by an attorney.

28

(iv)          If no amicable resolution or settlement is reached within sixty (60) days as a result of the procedures in Sections 9.6(a)(i) - (iii) above, the Dispute shall be finally resolved through binding arbitration which shall be conducted expeditiously.  Seller and Buyer and the arbitration panel shall endeavor to complete the arbitration process within one hundred twenty (120) days of the first status conference before the arbitrators.  Unless otherwise agreed to by the Parties, arbitration shall be conducted in accordance with the Commercial Arbitration Rules of the American Arbitration Association (the “Rules”).

(A)          The arbitration shall be conducted by a panel of three (3) arbitrators.  Each side shall be permitted to nominate one arbitrator and the two Party-nominated arbitrators shall confer and attempt to agree on a suitable third arbitrator who will serve as chair for the arbitration panel within five (5) Business Days or such other time as the Parties may agree.  If the two Party-nominated arbitrators are unable to agree on a third arbitrator, or if any Party fails to nominate an arbitrator as herein provided, the arbitrators shall be appointed in accordance with the Rules.  In any event, all arbitrators appointed hereunder shall have expertise relevant to the matter under dispute.

(B)          Unless the Parties agree otherwise, the place of arbitration shall be Denver, Colorado. The arbitrators shall not be empowered to award any form of punitive, incidental or consequential damages that are waived under this Agreement.  As part of any arbitral award pursuant to this paragraph, the arbitrators shall render a reasoned award.  The Parties consent to judgment on such award being entered in any court having jurisdiction.

(C)          Pending final resolution of the Dispute and award as described in Section 9.6(c) below each Party shall bear the costs of preparing its own claims and/or defenses (including its own attorneys’ fees), however the Parties shall share equally the costs of the arbitration, including the arbitrators’ fees.

(b)           The dispute resolution proceedings contemplated by this provision shall be as confidential and private as permitted by Law or the rules of any applicable securities exchange.  To that end, the Parties shall not disclose the existence, content or results of any proceedings conducted in accordance with this provision, and materials prepared or submitted in connection with such proceedings shall not be admissible in any other proceeding; provided, however, that this confidentiality provision shall not prevent a petition to vacate or enforce an arbitral award, and shall not bar disclosures required by Law or, in the judgment of such disclosing Party, required by any applicable securities exchange or the regulations thereof.  The Parties agree that any decision or award resulting from proceedings in accordance with this dispute resolution provision shall have no preclusive effect in any other matter involving third parties.

(c)           Should any Party institute any arbitration (or court proceeding, to the extent permitted) under this Section 9.6 to enforce any provision hereof or for damages by reason of the breach, default or liability of the other Parties arising out of any provision of this Agreement or otherwise, the prevailing Party (as determined by the arbitral panel or court) shall be entitled to

29

recover costs of the arbitration or court proceeding and reasonable attorneys’ fees to be fixed by the arbitral panel or court.

(d)           Each Party is required to continue to perform its obligations under this Agreement pending final resolution of any Dispute.

(e)           Any judicial proceedings permitted to be brought with respect to this Agreement shall be brought in any state or federal court of competent jurisdiction in the State of Colorado and the Parties generally and unconditionally accept the exclusive jurisdiction of such courts.  The Parties waive, to the fullest extent permitted by applicable Law, any objection which they may now or hereafter have to the bringing of any such action or proceeding in such jurisdiction.

(f)            Notwithstanding the agreement to arbitrate Disputes that do not require injunctive relief, the Parties agree that each may petition a court of competent jurisdiction to address issues that require injunctive relief from a court and are not properly subject to arbitrability.

9.7          Entire Agreement and Modifications.

(a)           This Agreement and the other Transaction Documents constitute the entire agreement between the Parties with respect to the subject matter hereof and thereof, superseding all prior statements, representations, discussions, agreements and understandings relating to such subject matter; provided, however, that the Confidentiality Agreement shall remain in effect until and unless the execution of this Agreement and the consummation of the Transactions occurs.

30

(b)           Except as otherwise specifically provided in this Agreement, all covenants, agreements, representations, guaranties, indemnities, and warranties shall survive the execution of this Agreement and the consummation of the Transactions, and the delivery and recordation of deeds, assignments or bills of sale which convey the Transferred Properties to Buyer.  Buyer acknowledges that (i) it is not relying on any representation (written or verbal) by Seller or its Affiliates that is not specifically set forth in the Transaction Documents, and (ii) it is relying solely on the representations set forth in the Transaction Documents and its own evaluation in making its decision to enter into the Transaction Documents to which it is a party and the Transactions.

(c)           No amendment or modification to this Agreement shall be binding unless made in writing and signed by all Parties.  The waiver or failure of any Party to enforce any provision of this Agreement shall not be construed or operate as a waiver of any further breach of such provision or of any other provision of this Agreement.

9.8          Parties in Interest.  Nothing in this Agreement, whether express or implied, is intended to confer any rights or remedies under or by reason of this Agreement on any persons other than the Parties, their respective successors and assigns and any Indemnitee entitled to the benefit of the indemnification provisions of Article 8 hereof, nor is anything in this Agreement intended to relieve or discharge the obligation or liability of any third person to any Party to this Agreement, nor shall any provision of this Agreement give any third persons any right of subrogation or action over and against any Party to this Agreement.

9.9          Severability.  In the event any provision of this Agreement is held to be invalid by a court or arbitrator of competent jurisdiction, the invalidity of any such provision shall in no way affect any other provision contained herein; provided, however, that any such invalidity does not materially prejudice any Parties in their respective rights and obligations contained in the valid provisions of this Agreement. Upon such determination that any term or other provision is invalid, illegal or incapable of being enforced, the remainder of this Agreement will be interpreted so as to best accomplish the intent of the Parties within the limits of applicable Law.

9.10        Records and Assistance.

(a)           For a period which meets the minimum standards of Buyer’s internal policies for record retention (but in any event, no less than three (3) years after the Closing Date), Buyer will retain any records evidencing the operation and maintenance obligations or the cost of reimbursement rights of Buyer hereunder or otherwise relating to the Transferred Properties prior to the Closing Date (the “Records”), and will make such Records available to Seller for inspection and copying upon reasonable notice at Buyer’s headquarters (or at such other location in the United States as Buyer shall designate in writing to Seller) at reasonable times and during regular office hours. In addition, Buyer will cooperate in providing information required by Seller to complete reports, statements, or other submissions required by Law, without regard to whether such information is contained in the Records.  Following the expiration of such period, Buyer may destroy such Records, provided that until the fifth (5th) anniversary of the Closing Date, Buyer shall provide Seller with sixty (60) calendar days’ prior written notice of Buyer’s intent to destroy any material Records transferred to Buyer pursuant to this Agreement and if Seller do not consent to the proposed destruction of Records, Buyer shall either continue to retain

31

the Records and continue to make them available to Seller as provided in the preceding sentence or require Seller to remove such records at Seller’s cost and expense.  To the extent Buyer receives copies of the Records because such Records relate to both the Transferred Properties and properties excluded from the Transferred Properties, Buyer shall maintain those portions of the Records which do not relate solely to the Transferred Properties strictly confidential and shall not disclose any such Records to any person or agency, unless such disclosure is required by Law or has otherwise been made publicly available

(b)           Notwithstanding the provisions of clause (a) above, Seller shall make arrangements to have any tax records located at the Transferred Properties removed within sixty (60) days of the Closing Date.  Buyer may request copies, at Buyer’s expense, of any such designated tax records either prior to the sixtieth day after the Closing Date or thereafter upon written request of Seller.

(c)           In the event of any dispute with respect to the ownership of the Transferred Properties arising out of events which occurred prior to the Closing Date, Buyer shall reasonably cooperate with Seller and their Affiliates, at Seller’s sole cost and expense, in the resolution of such dispute, including appearing in any litigation which may result therefrom; provided however, Buyer shall not be obligated to cooperate in any such dispute (nor appear in any related litigation) if such dispute involves (y) the Buyer or its Affiliates, (z) any third party with whom the Buyer is a counterparty as a result of the Transactions; provided further, however, that Buyer’s agreement to so cooperate shall not be deemed an acceptance by Buyer of any liability arising from such dispute, as to which the other provisions of this Agreement shall control.  Subject to execution of a customary non-disclosure agreement among Buyer and Seller, Buyer shall make available to Seller, upon Seller’s request at all reasonable times, any and all files and business records in Buyer’s custody or control transferred to Buyer hereunder and, except in the case of a conflict of interest between the Parties, any and all individuals employed by Buyer whose testimony or knowledge in the opinion of Seller’s counsel may be necessary or useful to it concerning the issues involved in such claims or litigation or in anticipation thereof. Seller and Buyer agrees to preserve all documents required to be preserved by any statutes, regulations, ordinances, orders, and other government requirements.

(d)           While Seller and its Affiliates are transferring books and records pertaining to the Transferred Properties to Buyer, such transferors by such act in no way intend to waive their respective attorney-client and work product privileges as to such documents which may be contained in such books and records and in particular with respect to those files associated with outstanding claims and lawsuits which have been identified in this Agreement.  Buyer shall continue to maintain the confidential status of those files or turn them over to Seller or its Affiliates if so requested.

9.11        Counterparts.  This Agreement may be executed in two or more counterparts and by different Parties on separate counterparts, all of which shall be considered one and the same agreement, and each of which shall be deemed an original.  Signatures delivered by facsimile or by e-mail in portable document format (pdf) shall be binding for all purposes hereof.
