(i) At least five Business Days before the Closing, Seller shall prepare and deliver to Purchaser a statement (the “Estimated Closing Working Capital Statement”) setting forth (A) its good faith estimate of the Closing Working Capital (the “Estimated Closing Working Capital”) and its calculation thereof, (B) an estimated balance sheet of the Company as of the Closing Date (without giving effect to the transactions contemplated herein), and (C) a certification of Seller that the Estimated Closing Working Capital Statement was prepared in accordance with IFRS applied using the same methodologies, practices, estimation techniques, assumptions, policies and principles used in the preparation of the Balance Sheet.

(ii) The “Closing Adjustment” shall be an amount equal to the Estimated Closing Working Capital minus the Target Working Capital. If the Closing Adjustment is a positive number, the Purchase Price shall be increased by the amount of the Closing Adjustment. If the Closing Adjustment is a negative number, the Purchase Price shall be reduced by the amount of the Closing Adjustment.

(iii) If Closing occurs after December 31, 2015, the aggregate Purchase Price shall be adjusted by subtracting therefrom the amount of the Company’s earnings before interest and taxes from and including January 1, 2016 to the Closing Date.

(i) Within 90 days after the Closing Date, Seller shall prepare and deliver to Purchaser a statement (the “Closing Working Capital Statement”) setting forth (A) its calculation of the Closing Working Capital, (B) an unaudited balance sheet of the Company as of the Closing Date (without giving effect to the transactions contemplated herein), and (C) a certification of Seller that the Closing Working Capital Statement was prepared in accordance with IFRS applied using the same methodologies,

practices, estimation techniques, assumptions, policies and principles used in the preparation of the Balance Sheet.

(ii) The “Post-Closing Adjustment” shall be an amount equal to the Closing Working Capital minus the Estimated Closing Working Capital. If the Post-Closing Adjustment is a positive number, Purchaser shall pay to Seller an amount equal to the Post-Closing Adjustment. If the Post-Closing Adjustment is a negative number, Seller shall pay to Purchaser an amount equal to the Post-Closing Adjustment.

(iii) After receipt of the Closing Working Capital Statement, Purchaser shall have 30 days (the “Review Period”) to review the Closing Working Capital Statement. During the Review Period, Purchaser and its representatives shall have access to the books and records of the Company, the personnel of, and work papers prepared by, Seller and its representatives to the extent that they relate to the Closing Working Capital Statement as Purchaser may reasonably request for the purpose of reviewing the Closing Working Capital Statement and to prepare a Statement of Objections (defined below).

(iv) On or prior to the last day of the Review Period, Purchaser may object to the Closing Working Capital Statement by delivering to Seller a written statement setting forth Purchaser’s objections in reasonable detail, indicating each disputed item or amount and the basis for Purchaser’s disagreement therewith (the “Statement of Objections”). If Purchaser fails to deliver the Statement of Objections before the expiration of the Review Period, the Closing Working Capital Statement and the Closing Working Capital reflected in the Closing Working Capital Statement shall be deemed to have been accepted by Purchaser. If Purchaser delivers the Statement of Objections before the expiration of the Review Period, Purchaser and Seller shall negotiate in good faith to resolve such objections within 30 days after the delivery of the Statement of Objections (the “Resolution Period”), and, if the same are so resolved within the Resolution Period, the Closing Working Capital and the Closing Working Capital Statement with such changes as may have been previously agreed in writing by Purchaser and Seller, shall be final and binding.

(v) If Seller and Purchaser fail to reach an agreement with respect to all of the matters set forth in the Statement of Objections before expiration of the Resolution Period, then any amounts remaining in dispute (the “Disputed Amounts”) shall be submitted for resolution to the Independent Accountant who, acting as experts and not arbitrators, shall resolve the Disputed Amounts only and make any adjustments to the Closing Working Capital and the Closing Working Capital Statement. The Parties agree that all adjustments shall be made without regard to materiality. The Independent Accountant shall only decide the specific items under dispute by the Parties and its decision for each Disputed Amount must be within the range of values assigned to each such item in the Closing Working Capital Statement and the Statement of Objections.

(vi) The Independent Accountant shall make a determination as soon as practicable within 30 days (or such other time as the Parties shall agree in writing) after its engagement, and its resolution of the Disputed Amounts and its adjustments to the Closing Working Capital and the Closing Working Capital Statement shall be conclusive and binding upon the Parties.

(vii) The fees and expenses of the Independent Accountant shall be allocated to be paid by Seller and Purchaser based upon the percentage that the amount actually contested but not awarded to Seller or Purchaser, respectively, bears to the aggregate amount actually contested by Purchaser.

(viii) Any payment of the Post-Closing Adjustment shall (A) be due (x) within five Business Days of acceptance of the Closing Working Capital Statement or (y) if there are Disputed

Amounts, then within five Business Days of the Independent Accountant’s resolution of the Disputed Amounts; and (B) be paid by wire transfer of immediately available funds to such account as is directed by Purchaser or Seller, as the case may be.

(e) Coal Stockpile Adjustment.

(i) No earlier than five (5) days before the Closing Date, the volume of the Stockpile Coal shall be photographed using aerial photography by Aero Graphics or Cooper Aerial Surveys Co. (or if neither are available, another company mutually agreed to by the Parties) and promptly thereafter measured using photogrammatic procedures by Aero Graphics (or if Aero Graphics is not available, by another company mutually agreed to by the Parties). The volume measured through that process shall be the “Starting Volume.” The Starting Volume will then be converted to the “Starting Tonnage” by multiplying the Starting Volume by the average bulk density of the Stockpile Coal for the twelve (12) months immediately preceding the date of this Agreement, which is 81.3 lbs/ft³. The “Coal Stockpile Tonnage” as of the Closing Date will be determined by calculating the change in the tonnage from the Starting Tonnage on the date photographed to the Closing Date. This shall be determined by calculating the difference between the measurement of the tonnages recorded on the ROM Belt Scale as input and the Coal Plant Belt Scale as output and adding it to the Starting Tonnage. Purchaser shall have the right to observe the operations and measurements related to the Coal Stockpile Tonnage. The calculation of the Coal Stockpile Tonnage shall be completed promptly after the Closing Date.

(ii) The “Coal Stockpile Target Tonnage” as of Closing shall be 4.8 million tons plus or minus 200,000 tons, with an average calorific value greater than or equal to 9,000 Btu/lb. The “Coal Stockpile Tonnage Excess” shall be the amount, if any, by which the Coal Stockpile Tonnage exceeds the Coal Stockpile Target Tonnage. The “Coal Stockpile Tonnage Shortfall” shall be the amount, if any, by which the Coal Stockpile Target Tonnage exceeds the Coal Stockpile Tonnage. For the avoidance of doubt, the Coal Stockpile Tonnage Excess shall be coal volumes above 5.0 million tons and the Coal Stockpile Tonnage Shortfall shall be coal volumes below 4.6 million tons.

(iii) If a Coal Stockpile Tonnage Excess exists, then Purchaser shall pay to Seller an amount equal to US$10.00 per ton of the Coal Stockpile Tonnage Excess.

(iv) If a Coal Stockpile Tonnage Shortfall exists, then Seller shall pay to Purchaser an amount equal to US$10.00 per ton of the Coal Stockpile Tonnage Shortfall.

(v) All amounts to be paid by a Party pursuant to this Section 2.1(e)(v) shall be paid promptly upon determination of such amounts by a wire transfer of immediately available funds to an account designated by the Party to whom such amounts are owed.

(f) San Juan Mine Employees’ Liabilities Adjustment.

(i) No later than thirty (30) days before Closing, Purchaser shall identify in writing to Seller any employees of BBNMC to become San Juan Mine Employees on or before Closing. Upon receipt of such information, Seller shall promptly transfer such identified employees to become San Juan Mine Employees. No later than fifteen (15) days before Closing, Seller shall provide to Purchaser the following information: (x) annual leave balances as of July 1, 2015 for the people who are expected to be San Juan Mine Employees on the Closing Date; (y) estimated annual leave balances as of the Closing Date for the people who are expected to be San Juan Mine Employees on the Closing Date; and (z) estimated accrued bonuses as of the Closing Date for the people who are expected to be San Juan Mine Employees on the Closing Date.

(ii) The Purchase Price shall be adjusted by (y) an amount equal to the difference between the annual leave balances as of July 1, 2015 for the people who are San Juan Mine Employees on the Closing Date minus the estimated annual leave balances as of the Closing Date for the people who are San Juan Mine Employees on the Closing Date and (z) reducing the Purchase Price by the estimated accrued bonuses as of the Closing Date for the people who are San Juan Mine Employees on the Closing Date, all as calculated by the Seller as described in Section 2.1(f)(i) (collectively, the “Estimated Employee Liability Adjustment”). If the difference between the annual leave balance described above on July 1, 2015 and the Closing Date is a positive number, the Purchase Price shall be increased by that number. If the difference between the annual leave balance described above on July 1, 2015 and the Closing Date is a negative number, the absolute value of the difference shall be subtracted from the Purchase Price.

(iii) Within 90 days after the Closing Date, Seller shall prepare and deliver to Purchaser a statement of calculations as of the Closing Date of the actual amounts of the items described in 2.1(f)(ii)(the “Closing Employee Liability Adjustment”). The “Post-Closing Employee Liability Adjustment” shall be an amount equal to the Closing Employee Liability Adjustment minus the Estimated Employee Liability Adjustment. If the Post-Closing Employee Liability Adjustment is a positive number, Purchaser shall pay Seller an amount equal to the Post-Closing Employee Liability Adjustment. If the Post-Closing Employee Liability Adjustment is a negative number, Seller shall pay to Purchaser an amount equal to the absolute value of the Post-Closing Employee Liability Adjustment.

(iv) Purchaser shall have thirty (30) days after receipt of Seller’s Closing Employee Liability Adjustment to object to Seller’s Closing Employee Liability Adjustment. During the thirty day period, Purchaser and its representatives shall have access to the books and records of the Company, the personnel of, and work papers prepared by, Seller and its representatives to the extent they relate to the Closing Employee Liability Adjustment as Purchaser may reasonably request for the purpose of reviewing such calculations and preparing objections.

(v) Purchaser’s process for providing objections, the resolution of such objections, and the payment of any shall be the same as provided for with regard to the Working Capital Adjustment, set forth in Section 2.1(d)(iv) through Section 2.1(d)(viii).

(g) Adjustments for Tax Purposes. Any payments made pursuant to Section 2.1(d) and Section 2.1(e) shall be treated as an adjustment to the Purchase Price by the Parties for Tax purposes, unless otherwise required by Law.

(h) UG-CSA Final Invoicing and True Up.

(i) The adjusted Interim Invoice, as defined in the UG-CSA; the UG-CSA Invoice, as defined in the UG-CSA; and the final invoice under the CCBDA will be sent to the Utilities after the Closing. The amounts in such invoices shall be Reimbursable Amounts. Seller shall cooperate with Purchaser to prepare such invoices, and Seller shall use its Commercially Reasonable Efforts to send such invoices in accordance with the provisions of the UG-CSA and CCBDA, as applicable, with a request to the Utilities that amounts for each invoice be paid directly to the Seller. Amounts received by Purchaser from such invoices, if any, shall be paid to Seller promptly after receipt thereof by Purchaser.

(ii) UG-CSA Invoices, as defined in the UG-CSA and Interim Invoices, as defined in the UG-CSA, are delivered monthly with a true-up process at the end of each calendar year at which time Utilities are to pay or the Company is to credit any difference between Interim Invoices and UG-CSA Invoices for such calendar year. The Seller shall cooperate with the Purchaser in preparing the true-up in accordance with the terms of the UG-CSA and the UG-CSA Termination and Mutual Release

Agreement, if applicable, and Seller shall use its Commercially Reasonable Efforts to send such invoices in accordance with the provisions of the UG-CSA and the UG-CSA Termination and Mutual Release Agreement, if applicable, with a request to the Utilities that amounts owed by the Utilities for the Pre-Closing Date Period be paid directly to the Seller. Amounts received by Purchaser from such true-up process, if any, shall be paid to Seller promptly after receipt thereof by Purchaser.

2.2 The Closing. Unless this Agreement shall have been terminated pursuant to Article VIII, subject to the satisfaction or waiver of the conditions set forth in Article VI and Article VII (collectively, the “Closing Conditions”), the closing (the “Closing”) of the Transaction shall take place remotely via the exchange of documents and signatures on December 15, 2015, and shall be effective as of 11:59 p.m., Albuquerque, New Mexico time on the later of (i) December 31, 2015 or (ii) ten (10) days after satisfaction of all of the conditions set forth in Article VI and Article VII (the date on which the Closing occurs, the “Closing Date”).

3.12 Tax Matters.

(a) All material Tax Returns required to be filed by or with respect to the Company have been timely and properly filed (taking into account extensions of time to file), and all such Tax Returns were true, correct and complete in all material respects when filed or validly amended. The Company has paid all material Taxes shown thereon or otherwise due from the Company (except for Taxes that may result from the transactions contemplated by this Agreement). Except as set forth on Schedule 3.12(a), the Company

is not currently the beneficiary of an extension of time within which to file any Tax Return. The Company does not have and, prior to the Closing Date, will not have any liability for Taxes of any Person (other than either Company) as a result of being a member of any affiliated, consolidated, combined unitary or similar group under Treasury Regulation Section 1.1502-6 (or any similar provision of state, local or non-U.S. Law) or as a transferee, successor or guarantor, or by contract, indemnification or otherwise.

(b) There are no Encumbrances, other than Permitted Encumbrances, for Taxes upon the properties or assets of the Company. The unpaid Taxes of the Company (A) did not, as of the Balance Sheet Date, exceed the reserve therefor (rather than any reserve for deferred Taxes established to reflect timing differences between book and Tax income) set forth on the face of the Balance Sheet (rather than in any notes thereto) and (B) do not exceed that reserve as adjusted for the passage of time through the Closing Date in accordance with the past custom and practice of the Company or the Seller Group in filing Tax Returns. Since the Balance Sheet Date, the Company has not incurred any liability for Taxes arising from extraordinary gains or losses, as that term is used in IFRS, outside the ordinary course of business consistent with past custom and practice.

(c) The Company has timely withheld, or collected, and paid all Taxes required to be withheld or collected (other than any Taxes attributable in whole or in part to the transactions contemplated by this Agreement), and all such Taxes have been paid over to the appropriate Taxing Authority or Governmental Authority. The Company does not have any liability or obligation to remit any amounts with respect to any escheat or state forfeiture laws, except to the extent set forth on the Balance Sheet.

(d) To the Knowledge of Seller, no written claim has been made by any Taxing Authority in a jurisdiction where the Company does not file Tax Returns that the Company was, is, or may be, subject to taxation by that jurisdiction, nor is there any reasonable basis for such a claim. The Company (A) is not and has not been a ‘‘controlled foreign corporation’’ as defined in Code Section 957, (B) is not and has not been a “passive foreign investment company” within the meaning of Code Section 1297, and (C) does not have a permanent establishment (within the meaning of an applicable Tax treaty) or otherwise has an office or fixed place of business in a country other than the United States.

(e) All deficiencies for Taxes proposed or asserted, and all Tax assessments made have been fully paid. Except as set forth on Schedule 3.12(e), there is no pending or, to the Knowledge of the Seller, threatened Proceeding with any Governmental Authority for the assessment or collection of any Taxes, against or with respect to the Company, nor are there any audits or investigations by any Taxing Authority or Proceedings in progress, nor has the Company received any written notice from any Taxing Authority that it intends to conduct such an audit or investigation, nor does Seller or any officer (or employee) responsible for Tax matters of Company expect any authority to assess any additional Taxes for any period for which Tax Returns have been filed. There are no outstanding agreements or waivers extending the statutory period of limitation applicable to any claim for, or the period for the collection or assessment of, Taxes due from or with respect to the Company, for any taxable period ending on or prior to the Closing Date. Schedule 3.12(e) lists all federal, state, local, and foreign income Tax Returns filed with respect to any of the Company for taxable periods ended on or after December 31, 2011 and indicates those Tax Returns that have been audited. Seller has delivered to Purchaser correct and complete copies of all federal income Tax Returns, examination reports, and statements of deficiencies assessed against or agreed to by the Company since December 31, 2011.

(f) Except as set forth on Schedule 3.12(f), the Company has not waived any statute of limitations in respect of Taxes, or agreed to any extension of time with respect to a Tax assessment or deficiency, which waiver or agreement is currently in effect.

(g) Except as set forth on Schedule 3.12(g), no power of attorney that is currently in force has been granted by the Company with respect to any Tax matter. The Company has not requested or received any written ruling from any Governmental Authority relating to Taxes, and no request for such ruling is pending.

(h) Seller is not a “foreign person” as that term is used in Treasury Regulations Section 1.1445-2.

(i) Except as set forth on Schedule 3.12(i), there are no tax sharing, allocation, indemnification, or similar agreements or arrangements in effect between the Company (or any predecessor or Affiliate thereof)), and any other Person under which the Company could be liable for any Taxes, or other claims of any other Person, or for which the Company will have any liability at or after the Closing.

(f) (i) No event has occurred that (with or without notice or lapse of time, or both) would constitute a breach or default under the Financing Letter, (ii) Purchaser is not aware of any fact, event or other occurrence that makes any of the representations or warranties of Purchaser in the Financing Letter inaccurate, and (iii) Purchaser has no reason to believe that any of the conditions in the Financing Letter will fail to be timely satisfied or that the full amount of the Financing will not be funded at the Closing.

ARTICLE VCOVENANTS OF THE PARTIES

5.1 Conduct of Business During the Interim Period.

(a) During the Interim Period, except as disclosed on Schedule 5.1(a) or with the prior written consent of Purchaser, Seller will: (A) use its Commercially Reasonable Efforts to cause the Company to operate the Business in the Ordinary Course of Business, in accordance with prudent mining standards and practices and consistent with the operating plan described on Schedule 5.1 (the “Interim Operating Plan”), and in compliance with all Laws (including Environmental Laws), Governmental Orders, Material Contracts and Material Permits, (B) use its Commercially Reasonable Efforts to ensure that the obligations of the Company will be paid or performed when due (and that the Company will not change in any material respect its practices in connection with the payment of accounts payable in respect of its purchases), (C) use its Commercially Reasonable Efforts to cause the present organization and business relationships and customer relationships of the Company to be preserved and their respective rights and operations to be maintained in all material respects, (D) use its Commercially Reasonable Efforts to cause the Company to keep in full force and effect insurance comparable in amount and scope of coverage to that currently maintained by the Company, (E) use its Commercially Reasonable Efforts to cause the Company to maintain, renew, keep in full force and effect and preserve its corporate existence, business organization and material rights, franchises, Permits and licenses and (F) promptly notify Purchaser of any Proceeding pending (or to the Knowledge of Seller, threatened) against the Company, the Company’s assets and/or the Business that, if adversely decided against the Company could have a Material Adverse Effect.

(b) During the Interim Period, except as disclosed on Schedule 5.3(b) or with the prior written consent of Purchaser, Seller will not: (A) cause the Company to make any capital expenditure, merger or other fundamental change, significant disposition or significant acquisition that is not included in the Interim Operating Plan, (B) amend the Organizational Documents of the Company, (C) cause the Company to make any material change in any method of accounting or in any of its accounting practices, (D) cause the Company to enter into any contract that would constitute a Material Contract, (E) cause the Company to amend or terminate any Material Contract other than as expressly contemplated by this Agreement, or (F) cause the Company to incur or otherwise become liable for any indebtedness for borrowed money that will remain outstanding as of the Closing or amend or terminate any instrument governing indebtedness of the Company outstanding as of the date hereof.

5.2 Access; Cooperation and Further Assurances; Notice of Developments; Real Property Review.

(a) During the Interim Period, Seller will cause the Company to afford Purchaser and its officers, employees, accountants, counsel and other authorized representatives, access, during normal business hours and in accordance with the Company’s safety protocols, to the Company and its properties, contracts, documents, dates, commitments, books and records and to make copies of such books, records,

contracts, data, information and documents as Purchaser may reasonably request; provided, however, that nothing in this Section 5.2(a) or elsewhere in this Agreement shall be construed to require Seller to prepare any reports, analyses, appraisals, opinions or other information or to require Seller to allow Purchaser or its officers, employees, accountants, counsel and other authorized representatives to conduct environmental sampling of any kind at any real property used by the Company in connection with the Company’s operations without the prior written consent of Seller (which may be withheld in Seller’s sole discretion). Subject to compliance with applicable Law, during the Interim Period, Seller shall, and shall cause the Company to, confer with Purchaser on a regular and frequent basis to report operational matters and the general status of ongoing operations and Business of the Company.

(b) Prior to and following the Closing, Seller and Purchaser will from time to time, execute and deliver such additional instruments, documents, assignments, conveyances or assurances and take such other actions as shall be necessary, or otherwise reasonably requested by the other Party to confirm and assure the rights and obligations provided for in this Agreement and render effective the consummation of the Transaction. Without limiting the foregoing, Seller and Purchaser shall cooperate with one another (i) in determining whether any action by or in respect of, or filing with or notification to, any Governmental Authority is required in connection with this Agreement and the consummation of the Transaction, and (ii) in taking such actions or making any such filings, furnishing information required in connection therewith and seeking timely to obtain any such actions, consents, approvals or waivers.

(c) From the date hereof until the Closing Date, Seller and Purchaser shall notify the other and PNM in writing if either Party acquires Knowledge of any fact or condition that causes the Closing Conditions of the non-breaching Party, as applicable, to be incapable of being satisfied or that may make the timely satisfaction of any of its covenants or conditions set forth in this Agreement impossible or unlikely. Should any such fact or condition require any change in the Disclosure Schedule (or the addition of one or more schedules to describe one or more exceptions to the representations and warranties set forth in Article III) if such Disclosure Schedule were dated the date of the occurrence or discovery of any such fact or condition, the Seller shall promptly deliver to the Purchaser and PNM a supplement to the Disclosure Schedule specifying such change(s). If the non-breaching Party has the right to terminate this Agreement pursuant to Section 8.1(b) as a result of such breach following the delivery of any notification or supplement pursuant to this Section 5.2(c) and does not do so within ten (10) Business Days, then all such disclosures included in such notification or supplement or any other notification or supplement delivered pursuant to this Section 5.2(c) delivered to the non-breaching Party prior to the first day of such ten (10) Business Day period shall be deemed accepted by the non-breaching Party and the conditions to Closing set forth in Section 6.1 and Section 7.1, as applicable, shall be deemed waived with respect to the matters so disclosed in any such notification or supplement, and the disclosure relative to any representations and warranties in this Agreement shall be deemed modified or supplemented as indicated in all such notifications and supplements. The Purchaser also hereby acknowledges and agrees that in no event shall the Seller have any liability whatsoever for, nor may the Purchaser invoke the failure of any Closing Condition or any termination right hereunder as a result of, any breach of any representation, warranty of covenant to the extent that the Purchaser had any Knowledge of such breach either on or prior to the date hereof.

(d) During the Interim Period, each of Seller, Purchaser and PNM will give prompt written notice to the others upon (a) receipt of any written notice from any Person alleging that the consent of such Person is or may be required in connection with the transactions contemplated by the Transaction Documents, (b) acquiring Knowledge of any Proceeding commenced or threatened against, relating to or involving or otherwise affecting the Company or, to the extent the subject matter of such Proceeding is directly related to the transactions contemplated by this Agreement, Seller or any of their respective Affiliates, or (c) receipt

of any written notice from any Governmental Authority directly in connection with the transactions contemplated by the Transaction Documents.

(e) (i) From and after the date of this Agreement until 5:00 p.m. Mountain time on the date that is ninety (90) days after the date of this Agreement (such date and time referred to herein as the “Real Property Review Deadline”), Purchaser shall have the right to: (A) obtain a title commitment (a “Title Commitment”) covering the Leased Real Property and any real property listed on Schedule 3.19(a) of this Agreement (collectively, the “Real Property”); (B) obtain a current survey (the “Survey”) of the Real Property by a licensed New Mexico surveyor; (C) examine title to the Real Property; and (D) notify Seller in writing (the “Title Objection Notice”) of any matters of title to which Purchaser objects (the “Title Objections”).

(ii) If Purchaser timely delivers to Seller a Title Objection Notice, then Seller shall use Commercially Reasonable Efforts prior to the Closing Date to resolve Purchaser’s Title Objections.

(iii) If Purchaser either does not object to any particular title or survey matter (whether by a failure to obtain the Title Commitment or Survey, to investigate such title or survey matters, or to object timely to such matters) or waives (or is deemed to have waived) any particular objection to title or survey matters, then Purchaser shall be deemed to have waived all objections contained in the Title Commitment and Survey or otherwise appearing of record or which would be reflected on a current and accurate survey of the Real Property. Purchaser acknowledges and agrees that, notwithstanding anything to the contrary in this Agreement, Purchaser’s obligation to consummate the transactions contemplated by this Agreement is not, in any way, conditioned on Seller having resolved Purchaser’s Title Objections.

5.3 Tax Matters

(a) Tax Returns. Seller shall prepare, or cause to be prepared, and timely file, or cause to be timely filed: (i) all income Tax Returns of the Company required to be filed for Pre-Closing Date Tax Periods, regardless of whether such income Tax Returns are filed before, on, or after the Closing Date; (ii) all other Tax Returns of the Company that are filed, or required to be filed (taking into account any valid extension of time to file), on or before the Closing Date; and (iii) any amendments to the Tax Returns described in clauses (i) or (ii) of this sentence (“Seller-Prepared Returns”). All Seller-Prepared Returns shall be prepared, and all determinations necessary to give effect to the foregoing allocations shall be made, in a manner consistent with prior practice of the Business and the Company to the extent permitted by applicable Law and in a manner that does not materially distort as between pre-Closing and post-Closing periods. Purchaser shall prepare, or cause to be prepared, and shall timely file, or cause to be timely filed all Tax Returns of the Company not described in the immediately preceding sentence (“Purchaser-Prepared Returns”). Subject to Seller’s right to payment pursuant to Section 2.1(h) and subject to Section 5.3(b), Seller shall be liable for (and, subject to the limitation set forth in Section 5.3(i), indemnify Purchaser and hold it harmless from and against) and shall pay all Taxes due with respect to Seller-Prepared Returns, and Purchaser or Company shall be liable for (and, subject to the limitation set forth in Section 5.3(b), indemnify Seller and hold it harmless from and against) and pay all Taxes due with respect to Purchaser-Prepared Returns. Seller shall provide copies of all Seller-Prepared Returns to Purchaser at least five (5) Business Days before the filing of each such Seller-Prepared Return. All refunds that may be received by the Company or Seller that would be payable to either or both of the Utilities without regard to this Agreement shall be paid to the Utilities and Seller shall have no right to such refunds, whether such refunds relate to Seller-Prepared Returns or Straddle Period Returns.

(b) Straddle Period Returns. Any Tax Return (other than an income Tax Return or a Tax Return for any Transfer Tax described in Section 2.4) filed for a taxable period that includes, but does not end on, the Closing Date (a “Straddle Period”) shall be referred to as a “Straddle Period Return”):

(i) All Straddle Period Returns shall be Purchaser-Prepared Returns. Purchaser shall provide to Seller a copy of any such Straddle Period Return, together with a written calculation (in accordance with Section 5.3(c)) determining the portion of the Tax for such Straddle Period that is allocable to the portion of the Straddle Period preceding and including the Closing Date, and Seller shall promptly reimburse and, subject to the limitation set forth in Section (i), indemnify Purchaser for and hold it harmless from and against such portion of the Tax (except to the extent that Seller is entitled to payment for such portion pursuant to Section 2.1(h) of this Agreement), subject to the rights of Seller set forth in Section 5.3(b)(ii).

(ii) Notwithstanding any provision in this Agreement to the contrary, if Seller disagrees with the calculation or allocation of Tax pursuant to a Straddle Period Return, Seller shall notify Purchaser of such disagreement within five (5) calendar days of receiving the calculation set forth in Section 5.3(b)(i) and the Parties shall negotiate in good faith to resolve such disagreement. If the Parties are unable to resolve such disagreement within thirty (30) days of Seller’s notice to Purchase of its disagreement, such disagreement shall be determined by an accounting firm of international reputation that is mutually agreeable to Purchaser and Seller (the “Tax Accountant”). Provided, however, if such accounting firm has provided services to Purchaser or Seller within the past sixty (60) months preceding such dispute between the Parties, that accounting firm may not be used if the Party not receiving services objects to the selection of that accounting firm. The Tax Accountant shall resolve such Tax dispute among and between the Parties contemplated by this Section 5.3(b). The Tax Accountant’s determination and resolution of the Tax dispute among and between the Parties contemplated by this Section 5.3(b) shall be final. The fees and expenses of the Tax Accountant shall be divided equally by Purchaser and Seller with each Party paying its allocated one-half of the expenses. If the Tax Accountant does not resolve any differences between Purchaser and Seller with respect to such Straddle Period Return at least five (5) calendar days prior to the due date therefor, such Straddle Period Return shall be filed as prepared by Purchaser and the Tax Accountant’s resolution shall control the rights of the parties under this Agreement.

(c) Calculation of Taxes for Straddle Period Returns. Except with respect to ad valorem property Taxes, Taxes accruing and payable for the Pre- Closing Date Tax Period (the “Pre- Closing Date Taxes”) for Straddle Period Returns shall be calculated as though the taxable period of the Company terminated as of the close of business on the Closing Date. In the case of ad valorem property Taxes, Pre- Closing Date Taxes shall be equal to the amount of ad valorem property Tax for the entire Straddle Period multiplied by a fraction, the numerator of which is the total number of calendar days from the beginning of the Straddle Period through and including the Closing Date and the denominator of which is the total number of calendar days in the Straddle Period. All Straddle Period Returns shall be prepared, and all determinations necessary to give effect to the foregoing allocations shall be made, in a manner consistent with prior practice of the Business and the Company to the extent permitted by applicable Law.

(d) Tax Return Amendments. After the Closing Date, the Purchaser or any Affiliate shall not amend, materially modify or otherwise change any Tax Return of the Company for any Pre-Closing Date Tax Periods or Straddle Periods, without the prior written consent of Seller.

(e) Cooperation. Seller, Purchaser, and the Company shall cooperate fully, as and to the extent reasonably requested by the other Party, in connection with the preparation and filing of Tax Returns pursuant to this Section 5.3 and any Tax Proceeding (as defined below). Such cooperation shall

include signing any Tax Returns, amended Tax Returns, claims or other documents necessary to settle or finally resolve any Tax Proceeding, the retention and (upon the other Party’s request) the provision of records, documents and information which are reasonably relevant to any such Tax Proceeding or other Proceeding and making employees available on a mutually convenient basis to provide additional information and explanation of any material provided hereby. The Party requesting assistance hereunder shall reimburse the other Party for reasonable out-of-pocket expenses incurred in providing such assistance.

(f) Tax Proceedings.

(i) Within three (3) Business Days of receipt of any proposed assessment or the commencement of any Tax audit or administrative or judicial proceeding or of any demand or claim on the Company, for any Tax Period ending on or before the Closing Date or involving a Straddle Period Return (each, a “Tax Proceeding”), the Purchaser shall notify the Seller in writing of the Tax Proceeding. After the Closing, Seller shall within three (3) Business Days of the receipt of any Tax Proceeding involving the Company notify Purchaser in writing of any Tax Proceeding. Notices required to be given by or to Purchaser or Seller shall contain factual information (to the extent known to Seller or Purchaser, as the case may be) describing the asserted Tax Liability in reasonable detail, and shall include copies of any notice or other document received from any Governmental Authority in respect of any such asserted Tax Liability.

(ii) In the case of a Tax Proceeding that relates solely to any Pre-Closing Date Tax Period, but excluding any Straddle Periods, Seller shall have the right to direct and control the conduct of such Tax Proceeding, provided Purchaser shall have the right to meaningfully participate (at Purchaser’s own expense) in any such Tax Proceeding. Purchaser’s right to participate shall include, but shall not be limited to, the right to receive copies of all correspondence from any Governmental Authority relating to such Tax Proceeding, attend meetings and review and comment on submissions relating to any Tax Proceeding, and Seller shall consider in good faith any comments provided by Purchaser. Seller may elect to waive Seller’s right under this Section 5.3(f)(ii) to direct and control any Pre-Closing Period Tax Proceeding. In the event Seller waives its right to direct and control any Pre-Closing Period Tax Proceeding, Purchaser shall assume control of such Tax Proceeding. Upon such a waiver, Seller shall have the right to meaningfully participate (at Seller’s own expense) in any such Tax Proceeding. Seller’s right to participate shall include, but shall not be limited to, the right to receive copies of all correspondence from any Governmental Authority relating to such Tax Proceeding, attend meetings and review and comment on submissions relating to any Tax Proceeding, and Purchaser shall consider in good faith any comments provided by Seller. Neither Purchaser nor the Company may settle or compromise any Tax Proceeding for any Pre-Closing Date Tax Period that would result in any Liability of Seller for Taxes without prior written consent of Seller, which consent shall not be unreasonably withheld, conditioned or delayed.

(iii) In the case of a Tax Proceeding that relates to any Straddle Periods, Purchaser shall have the right to control the conduct of such Tax Proceeding, provided Seller shall have the right to meaningfully participate (at Seller’s own expense) in any such Tax Proceeding involving any asserted Tax Liability for such Straddle Period with respect to which payment may be sought from the Seller pursuant to this Agreement. Seller’s right to participate shall include, but shall not be limited to, the right to receive copies of all correspondence from any Governmental Authority relating to such Tax Proceeding, attend meetings and review and comment on submissions relating to any Tax Proceeding, and Purchaser shall consider in good faith any comments provided by Seller. Neither Purchaser nor the Company may settle or compromise any Tax Proceeding for any Straddle Period that would result in any Liability of Seller for Taxes without prior written consent of Seller, which consent shall not be unreasonably withheld, conditioned or delayed.

(iv) The provisions of Section 5.3(f)(ii) and (iii) shall not apply with respect to any Tax Proceedings to the extent such Tax Proceedings relate to the Seller Consolidated or Combined Returns. Seller shall have the sole right to direct and control the conduct of any such Tax Proceeding.

(g) Documentation. Purchaser and Seller further agree, upon request from the other Party, to use their Commercially Reasonable Efforts to obtain any certificate or other document from any Governmental Authority or any other Person as may be necessary to mitigate, reduce or eliminate any Tax that could be imposed (including with respect to the Transaction). Purchaser and Seller further agree, upon request, to provide the other party with all information that either party may be required to report pursuant to Code Section 6043, or Code Section 6043A, or Treasury Regulations promulgated thereunder.

(h) Overpayments and Refunds. Any overpayment or refunds or credits of Taxes or other similar benefits of the Company with respect to any Pre- Closing Date Tax Period, together with any interest paid or credit with respect thereto, shall be for the account of Seller. Purchaser shall within five (5) Business Days after receipt or entitlement thereto, pay or cause to be paid to Seller any such refund and the dollar value of any such credit or benefit. If Seller determines that the Company is entitled to file or make a claim for a refund or credit or a Tax Return providing for a refund or credit with respect to a Pre- Closing Date Tax Period, Seller shall be entitled to file or make such claim or Tax Return (solely at Seller’s expense) on behalf of the Company and shall control the prosecution of such claim (so long as such refund or credit is solely for the account of Seller). Purchaser shall cooperate with any reasonable request by Seller relating to filing or making such claim or Tax Return or prosecuting such claim, including but not limited to signing a claim for refund or an amended Tax Return.

(i) Limitation on Indemnity. Seller’s indemnification obligation set forth in this Section 5.3 shall be limited to amounts owed for Taxes other than taxes or royalties that are reimbursable to SJCC under the UG-CSA or CCBDA. Further, Seller’s aggregate liability to Purchaser with respect to any indemnity obligations set forth in this Section 5.3 shall be limited to an amount equal to the Purchase Price.

(j) Tax Election.

(i) Purchaser is considering making an election under Section 338(h)(10) of the Code (and any corresponding election under state or local law) with respect to its purchase hereunder of all the issued and outstanding shares of SJCC and/or SJTC (collectively, the “338(h)(10) Election”). The decision whether to make the 338(h)(10) Election shall be solely that of Purchaser. If Purchaser determines to make such election, Seller hereby agrees to join with Purchaser in making the 338(h)(10) Election, and, in such case, Seller shall include any income, gain, loss, deduction, or other tax item resulting from the 338(h)(10) Election on its Tax Return to the extent required by applicable law, and Purchaser shall pay to Seller: (A) an amount equal to any additional Taxes imposed on Seller attributable to the making of the 338(h)(10) Election (including an amount equal to any additional Taxes on the amount described in this clause (A)) such that Seller will be in the same after-tax position following receipt of such payment as if no 338(h)(10) Election had been made; and (B) any reasonable costs and expenses incurred by Seller in joining with Purchaser in making the 338(h)(10) election, including reasonable accounting and legal fees. To facilitate the 338(h)(10) Election, Seller shall deliver to Purchaser at Closing two duly executed IRS Forms 8023, one with respect to SJCC and the other with respect to SJTC (collectively, “Form 8023”), electing to treat Purchaser’s purchase hereunder of all the issued and outstanding shares of SJCC, on the one hand, and SJTC, on the other hand, as qualified stock purchases under Section 338(h)(10) of the Code and shall take such other actions as may be reasonably requested by Purchaser to facilitate the 338(h)(10) Election, including joining in filing any comparable forms or other documents with respect to any state or local tax elections. Purchaser shall provide executed copies of Form 8023 to Seller within ninety (90) days

after Closing. If Purchaser determines not to make the 338(h)(10) Election with respect to SJCC and/or SJTC, Purchaser shall return to Seller the originally executed Form 8023 for SJCC and/or SJTC, as applicable, and all copies thereof.

(ii) Within 60 days after Closing, Purchaser shall send to Seller allocations of the Purchase Price among the assets of SJCC and SJTC, together with the relevant documentation, including all information required for completion of Form 8883. Such allocation shall be final and binding on Seller unless, within ten Business Days after the date of delivery by Purchaser of such allocation, Seller delivers to Purchaser a written request for changes to such allocation. If Seller delivers such a request, then Seller and Purchaser shall undertake in good faith to resolve the issues raised in such request within 30 days after receipt of such written request for changes by Purchaser. If Seller and Purchaser are unable to resolve any such issue within the 30-day period, Purchaser shall engage the Tax Accountant to resolve the dispute. The determination of the Tax Accountant will be final and binding on the parties hereto. The costs and expenses of the Tax Accountant with respect to determining the allocation will be shared equally by Purchaser and Seller. Within 45 days of Seller’s receipt of such allocation of the Purchase Price, if Seller does not timely send a written request for changes to such allocation, or, if Seller does timely send a written request for changes to such allocation, within 30 days of the determination of the disputed items (either through the agreement of Purchaser and Seller or the determination by the Tax Accountant, as the case may be), Seller shall send to Purchaser a calculation of any additional Taxes imposed on Seller attributable to the making of the 338(h)(10) Election (computed separately with respect to SJCC, on the one hand, and SJTC, on the other hand), together with all relevant documentation, plus a calculation of the marginal tax rate at which any such payments to Seller will be taxed (the calculation of the amount of incremental taxes grossed up for the taxes payable with respect to such payments, the “Incremental 338(h)(10) Tax Calculation” and the amount payable by Purchaser to Seller pursuant to the Incremental 338(h)(10) Tax Calculation, as ultimately determined pursuant to this Section 5.3(j)(ii), the “Incremental 338(h)(10) Tax Amount”). The Incremental 338(h)(10) Tax Calculation shall be binding and final unless, within 30 calendar days after delivery of the Incremental 338(h)(10) Tax Calculation to Purchaser, Purchaser delivers to Seller written objection to the Incremental 338(h)(10) Tax Calculation (an “Incremental 338(h)(10) Tax Calculation Objection Notice”). If Purchaser delivers an Incremental 338(h)(10) Tax Calculation Objection Notice within the specified time, authorized representatives of Purchaser and Seller shall promptly negotiate in good faith to resolve such objections. If Purchaser and Seller are unable to reach an agreement with respect to the objections within 30 calendar days after delivery of the Incremental 338(h)(10) Tax Calculation Objection Notice, Purchaser shall engage the Tax Accountant to review the Incremental 338(h)(10) Tax Calculation and resolve the objections. The costs and expenses of the Tax Accountant with respect to determining Seller’s Incremental 338(h)(10) Tax Amount shall be paid by Purchaser. If there is no timely Incremental 338(h)(10) Tax Calculation Objection Notice as provided above, the Incremental 338(h)(10) Tax Calculation shall be the binding and final determination of the Incremental 338(h)(10) Tax Amount. If there is a timely Incremental 338(h)(10) Tax Calculation Objection Notice, the Incremental 338(h)(10) Tax Amount as revised, if applicable, by the agreement of Purchaser and Seller or by the Tax Accountant shall be the binding and final determination of the Incremental 338(h)(10) Tax Amount.

(iii) Prior to Purchaser’s filing Form 8023 to make the 338(h)(10) Election with respect to its purchase of all the issued and outstanding shares of SJCC and/or SJTC, Purchaser shall pay to Seller the Incremental 338(h)(10) Tax Amount with respect to SJCC and/or SJTC, as applicable, as determined in Section 5.3(j)(ii); provided, however, that such payment need not be made prior to filing the 338(h)(10) Election if Seller did not timely provide the Incremental 338(h)(10) Tax Calculation as provided in Section 5.3(j)(ii) above (it being understood that when the Incremental 338(h)(10) Tax Amount for Seller is determined, Purchaser shall be responsible for such payment); and provided, further, that if Purchaser and Seller are still in the process of resolving the Incremental 338(h)(10) Tax Amount in accordance with

Section 5.3(j)(ii) at the time Purchaser makes the 338(h)(10) Election, Purchaser shall pay to Seller an estimate of the Incremental 338(h)(10) Tax Amount based on the Incremental 338(h)(10) Tax Calculation as provided by Seller. If the Incremental 338(h)(10) Tax Amount for Seller is ultimately determined to be a different amount, Purchaser or Seller, as applicable, shall pay to the other party the appropriate amount so that Seller has received the actual Incremental 338(h)(10) Tax Amount.

5.4 Further Actions.

(a) During the Interim Period, Purchaser and Seller shall use their respective Commercially Reasonable Efforts to take, or cause to be taken, all appropriate action, and do, or cause to be done, all things necessary, proper or advisable under applicable Laws or otherwise to consummate and make effective the Transaction as promptly as practicable, including the satisfaction of the Closing Conditions of such Party set forth in Article VI and Article VII, as applicable; provided that any obligation related to Permits shall be further subject to the terms of Section 5.7.

(b) Without limiting the generality of Section 5.4(a), each Party promptly shall make all filings and submissions and take all other actions necessary, proper or advisable under applicable Laws to obtain any required approval of any Governmental Authority with jurisdiction over the transactions contemplated hereby, including the HSR Act. Each Party shall furnish to the appropriate Governmental Authority all information required for any application or other filing to be made pursuant to any applicable Law in connection with the transactions contemplated hereby. The Parties shall, however, assert and permit the assertion of all applicable rights and privileges to withhold or prevent disclosure of information requested by any Governmental Authority, which is of a confidential or sensitive nature and not expressly and unambiguously required by applicable Law, including permitting a Party to intervene and be heard, and otherwise cooperating fully with that Party in any Proceedings relating to the disclosure of information to the extent permitted by applicable Law. Each of the Parties shall cooperate with the other in promptly filing any other necessary applications, reports or other documents with any Governmental Authority having jurisdiction with respect to this Agreement and the transactions contemplated hereby, and in seeking necessary consultation with and prompt favorable action by such Governmental Authority. If HSR filing is required, the Seller and Purchaser shall each pay ½ of the applicable filing fee.

(c) In the event any claim, action, suit, investigation or other Proceeding by any Governmental Entity or other Person is commenced that questions the validity or legality of the Transaction or seeks damages in connection therewith, the Parties shall (i) cooperate and use Commercially Reasonable Efforts to defend against such claim, action, suit, investigation or other Proceeding, (ii) in the event an injunction or other order is issued in any such action, suit or other Proceeding, use Commercially Reasonable Efforts to have such injunction or other order lifted, and (iii) cooperate reasonably regarding any other impediment to the consummation of the Transaction.

(d) During the Interim Period, Seller shall give prompt written notice to Purchaser of the occurrence of any Material Adverse Effect.

(e) Seller and Purchaser shall use Commercially Reasonable Efforts to satisfy all Closing Conditions on or before the proposed closing date of December 31, 2015.

5.5 Intercompany Accounts; Affiliate Agreements. All Intercompany Accounts shall be settled on the Closing Date in accordance with Seller’s past practice.

5.6 Substitute Bonds.

(a) Substitute Bonds. Purchaser shall obtain or cause to be obtained substitute surety bonds and/or letters of credit or provide other financial obligations or assurances acceptable to the regulating Governmental Authorities, including policies of insurance, all in form and substance acceptable to the applicable Governmental Authorities and Seller (collectively, “Substitute Bonds”), which Substitute Bonds (i) shall be submitted to the regulating Governmental Authorities for their review no less than thirty (30) days before the Closing Date and (ii) shall be effective and filed not later than the Closing Date in full substitution for all obligations of the Company under the Existing Bonds, and shall cooperate with Seller to obtain the release of all guarantees and collateral of the Company’s Affiliates securing the obligations of the Company under any of the Existing Bonds. Purchaser shall seek in good faith from the applicable Governmental Authorities reasonable assurances that the Substitute Bonds comply with applicable Law.

(b) Refund of Premiums; Return of Collateral. All funds in respect of premiums and collateral amounts that are refunded or released in respect of Existing Bonds and policies of insurance on account of the replacement thereof by Purchaser pursuant to this Section 5.6 shall be for the account of Seller and its Affiliates, and Purchaser hereby assigns to Seller any and all claims in respect of such premiums and collateral accounts, effective as of the Closing Date; provided that any such refunds are subject to the terms of the UG-CSA and CCBDA or the UG-CSA Termination and Mutual Release Agreement and CCBDA Termination and Mutual Release Agreement, as applicable. Purchaser shall pay over or cause the Company to pay over to Seller any such refunds or other amounts received by the Company after the Closing Date promptly upon receipt of such refunds or other amounts.

5.7 Permits. The Parties acknowledge and agree that the Transaction may necessitate one or more Governmental Approvals in relation to certain Permits (each a “Required Approval”), including a possible transfer, assignment or sale process for the SMCRA permit. Promptly following the date hereof, each Party shall use its Commercially Reasonable Efforts and cooperate in good faith with the other Party to make all necessary applications, filings and requests, furnish all required supporting materials, and take all other actions reasonably required to obtain all such Required Approvals. The Parties shall not request any material modification of such Permits in connection with the request for the consent of the appropriate Governmental Authorities to the transfer of such Permits. Notwithstanding the foregoing, the Parties acknowledge that as a condition to granting a Required Approval, the appropriate Governmental Authority may require modification of the subject Permits. The Parties shall consult with each other regarding any changes to the subject Permits requested by the appropriate Governmental Authority. The Parties shall agree to all reasonable modifications that will take effect as of the Closing Date to those subject Permits issued by Governmental Authorities that are requested by such Governmental Authorities as a condition to granting a Required Approval affecting the transfer of such subject Permits and upon the request of either Purchaser or Seller shall evidence such agreement in writing in a form satisfactory to the Party making such request acting reasonably; provided, that such modifications shall take effect only in the event of the occurrence of the Closing. To the extent any Material Permits are not transferrable, Purchaser shall be responsible for obtaining a new permit or license as necessary or desirable for Purchaser, and Seller shall use Commercially Reasonable Efforts to cooperate with Purchaser in relation to obtaining such new permit or license. To the extent any Permits, or applicable Law, require notices or other filings after Closing, Purchaser and/or the Company shall be responsible for such notices or filings.

5.8 Royalties. Seller shall provide notice to Purchaser within thirty (30) calendar days of receipt by Seller of any assessment, notice or demand for payment of any royalty which the Company disputes.

NLRB, 452 U.S. 661 (1981) and its progeny, to provide notice and a meaningful opportunity to the Union to engage in effects bargaining regarding the Transaction. Such notice will be timely provided to the Union in accordance with the NLRA following execution of this Agreement. The Seller and the Company will advise Purchaser of the outcome, if any, of effects bargaining with the Union. However, none of the above-described matters shall be regarded a condition to Closing hereunder.

5.12 Seller’s Covenants Regarding Employees and Employee Plans. Effective as of Closing, to the extent any Employee Plan does not have SJCC as the plan sponsor, Seller shall either (i) make SJCC the plan sponsor to the extent possible, but only if SJCC and SJTC are the only participating employers in the Employee Plan or (ii) create a clone document for SJCC to adopt as a spin-off of the larger plan for the purpose of covering the Company participants and no other employees in that Employee Plan. Solely for the Navajo Mine Retirement Plan, Seller will retain a plan solely covering active employees of Seller Group immediately after the Closing. All other portions of the Navajo Mine Retirement Plan not spun off to the Seller Group as described in the immediately preceding sentence, shall be assumed and sponsored by the Purchaser effective as of the Closing Date. The process described above shall not apply to any equity based plans providing for grants of equity in Seller or its Affiliates (collectively, “BHP Equity Plans”), to the BHP Minerals International LLC Stock Investment Plan, to post-retirement medical benefits for former employees of the Company who terminate service with the Company before Closing, or to any Employee Plan for which substantially equivalent benefits will be provided under a benefit plan maintained by Purchaser for its employees. The effective date of such spun-off plans shall be on or before the Closing Date. All assets and liabilities pertaining to the San Juan Mine Employees and former employees of SJCC shall be transferred to the spun-off plan as of the Closing Date.

Section 2102, et seq., and any similar foreign, state or local Law. All such Liabilities that accrue and/or vest from and after the Closing Date shall be the responsibility of Purchaser.

(b) Effective as of Closing, the Company shall be responsible as the plan sponsor for those Employee Plans that are transferred to the Company in accordance with Section 5.12 and all Liabilities related thereto.

(c) From the Closing Date until the expiration or termination of the CBA, as applicable, to afford all San Juan Mine Employees, including hourly and salaried employees, the protections and remedies provided by federal employment law and labor law, and to comply, and cause Company to comply, in all material respects with the terms of any federal and labor laws in respect of any of the San Juan Mine Employees and the terms of any CBA in respect of any of the San Juan Mine Employees subject to such an agreement.

If the Company terminates a San Juan Mine Employee without cause on or before the one year anniversary of the Closing Date, the Company shall pay to such San Juan Mine Employee a severance amount that is the greater of (y) any amount owed under an applicable severance policy or plan and/or any amount owed under an applicable employment agreement (such as pay in lieu of notice amounts) and (z) an amount equal to the terminated employee’s compensation for the remainder of the period to the one year anniversary of the Closing Date.

(e) From and after the Closing Date, Purchaser shall pay all amounts promised to be paid to SJCC Employees in relation to the freezing of the Retirement Income Plan.

(f) This Section 5.13 shall be binding upon and inure solely to the benefit of the respective Parties hereto, and nothing in this Agreement, express or implied, is intended to or shall confer upon any other Person (including any employees, former employees, any participant or any beneficiary thereof in any Seller Employee Plan or any employee benefit plan of Purchaser) any right, benefit or remedy of any nature whatsoever under or by reason of this Section 5.13. Nothing in this Agreement, express or implied, is intended to, and it shall not be construed to, amend any Employee Plan in any manner whatsoever.

(g) Purchaser shall enter into an employee matters agreement substantially in the form of Exhibit G (the “Employee Matters Agreement”) with Seller prior to Closing to address other matters concerning the San Juan Mine Employees and Employee Plans, to the extent deemed appropriate to the Seller and in a form and substance mutually agreed to by Seller and Purchaser. Such Employee Matters Agreement shall include, without limitation, transitions issues of (i) the disposition of any health and dependent care reimbursement accounts for San Juan Mine Employees, to include both the liability for amounts that are reimbursable under such accounts and the related amounts that have been contributed by San Juan Mine Employees to such accounts as of Closing; (ii) designation of which Party will be responsible for COBRA coverage for San Juan Mine Employees who terminate employment or have other COBRA “qualifying events” on or prior to Closing; (iii) how any out-of-pocket and deductible limits for health plan coverage of San Juan Mine Employees will be coordinated between the Employee Plans sponsored by the Company before and after the Closing; (iv) provisions for Seller’s retention of post-retirement medical obligations for employees of the Company who terminate service before Closing or within thirty (30) days after Closing; (v) provisions for any bonuses or incentive compensation that are expected to be payable after Closing and that are based on the performance of entities or businesses other than Purchaser, and (iv) post-closing payments of amounts described in Section 5.13(e). The Employee Matters Agreement will also address Purchaser’s obligation to establish benefit plans, programs, arrangements, agreements and policies, as described in Section 5.13(d)(iii) and, to the extent deemed appropriate by Seller, an agreement between

the Parties that they will share such information needed to accurately administer the employee benefit plans that cover the affected employees.

5.16 Excluded Contracts. Effective upon Closing, Seller shall terminate all Excluded Contracts. Purchaser acknowledges and agrees that Purchaser must make arrangements for replacement of the goods and services provided for under the Excluded Contracts.

5.17 Nonsurvival of Representations and Warranties. The representations set forth in Sections 3.1, 3.2, 3.3, 4.1, and 4.2 shall survive the Closing. Other than (i) in the case of intentional fraud and (ii) in the case of those representations set forth in the preceding sentence, no representations and warranties made by Seller and Purchaser in this Agreement or in any instrument delivered pursuant to this Agreement shall survive the Closing, and no Person shall have any Liability or obligation in connection with any such representation or warranty following the Closing.

5.18 Exclusivity. During the Interim Period, Seller will not, and will cause its Affiliates and its and its Affiliates’ representatives not to, directly or indirectly: (a) solicit, initiate, or encourage the submission of any proposal or offer from any Person relating to, or enter into or consummate any transaction relating to, the acquisition of any Shares or other equity securities in the Company or any merger, recapitalization, share exchange, sale of substantial assets or any similar transaction or alternative to the transactions contemplated hereby, or (b) participate in any discussions or negotiations regarding, furnish any information with respect to, assist or participate in, or facilitate in any other manner any effort or attempt by any Person to do or seek any of the foregoing.

5.19 Financing Matters.

(a) Purchaser Efforts. Purchaser shall use reasonable best efforts to take, or cause to be taken, all actions and to do, or cause to be done, all things reasonably necessary, proper or advisable to arrange and obtain the Financing on the terms and conditions described in the Financing Letter and shall not agree to any amendment or modification to be made to, or any waiver of any provision or remedy, under the Financing Letter without the prior written consent of Seller and PNM if such amendments, modifications or waivers would reasonably be expected to (i) reduce the aggregate amount of the Financing below the amount required to consummate the transactions contemplated by this Agreement and pay all related fees and expenses, (ii) impose new or additional conditions to the receipt of the Financing, (iii) prevent or materially delay the consummation of the transactions contemplated by this Agreement or (iv) adversely impact the ability of Purchaser to enforce its rights against the other parties to the Financing Letter; provided that, Purchaser may amend the Financing Letter to add lenders, arrangers, bookrunners, syndication agents or similar entities who have not executed the Financing Letter. Without limiting the foregoing, Purchaser shall use its reasonable best efforts to (A) maintain in effect the Financing Letter, (B) satisfy on a timely basis all conditions to obtaining the Financing, (C) enter into definitive agreements with respect to the Financing Letter on terms and conditions contained in the Financing Letter (including any “market flex” provisions

with respect to the Financing Letter) (or terms and conditions not materially less favorable, in the aggregate, to Purchaser than the terms and conditions in the Financing Letter), (D) in the event that all conditions in the Financing Letter have been satisfied, consummate the Financing at or prior to Closing, (E) enforce its rights under the Financing Letter, and (F) in the event that all conditions in the Financing Letter have been satisfied, cause the lenders and other persons providing the Financing to fund on the Closing Date the Financing required to consummate the transactions contemplated by this Agreement. Upon any amendment, supplement or modification of the Financing Letter in accordance with this Section 5.19, Purchaser shall provide a copy thereof to Seller and PNM and the term “Financing Letter” shall mean the Financing Letter as so amended, supplemented or modified.

(b) Alternate Financing. If any portion of the Financing becomes unavailable, or it becomes reasonably likely that such funds will be unavailable to Purchaser, on the terms and conditions contemplated in the Financing Letter, Purchaser shall, as promptly as practicable following the occurrence of such event, (i) notify Seller and PNM in writing thereof, (ii) use reasonable best efforts to obtain alternative financing (on terms in the aggregate not materially less favorable to Purchaser taken as a whole than the Financing contemplated by the Financing Letter) sufficient to enable Purchaser to consummate the transactions contemplated by this Agreement (the “Alternate Financing”); provided that such Alternate Financing shall not (A) be subject to any material additional conditions to the funding of the Financing than those contained in the Financing Letter or (B) otherwise be reasonably likely to impair or delay the Closing or the date on which the Financing would be obtained, and (iii) use reasonable best efforts to obtain a new financing letter that provides for such Alternate Financing and, promptly after execution thereof, deliver to Seller and PNM true, complete and correct copies of the new letter (including all annexes, exhibits, schedules and other attachments thereto) and related definitive financing documents with respect to such Alternate Financing. Upon obtaining any Alternate Financing, such financing shall be deemed to be a part of the “Financing” and any letter for such Alternate Financing shall be deemed the “Financing Letter” for all purposes of this Agreement.

(c) Notice of Default. Purchaser shall give Seller and PNM prompt notice: (i) of any breach or default (or any event or circumstance that, with or without notice, lapse of time or both, could reasonably be expected to give rise to any breach or default) by any party to the Financing Letter or other definitive document related to the Financing; (ii) of the receipt of any written notice or other written communication from any party to the Financing Letter with respect to any actual or threatened breach, default, withdrawal, termination or repudiation by any party to the Financing Letter or any definitive document related to the Financing or any provisions of the Financing Letter or any definitive document related to the Financing; (iii) of any material written dispute or disagreement between or among Purchaser and any of the other parties to the Financing Letter or any definitive document related to the Financing; (iv) of any amendment or modification of, or waiver under, the Financing Letter and (v) if for any reason Purchaser believes in good faith that it will not be able to timely obtain all or any portion of the Financing on the terms, in the manner or from the sources contemplated by the Financing Letter or the definitive documents related to the Financing. Purchaser shall keep Seller and PNM informed on a reasonably current basis in reasonable detail of the status of its efforts to arrange the Financing (or Alternate Financing obtained in accordance with Section 5.19(b)) and provide to Seller copies of all documents related to the Financing (or Alternate Financing obtained in accordance with Section 5.19(b)), other than any ancillary agreements subject to confidentiality agreements (except to the extent such agreements relate to the amounts or conditionality of, or contain any conditions precedent to, the funding of the Financing (or Alternate Financing obtained in accordance with Section 5.19(b), including any “market flex” provisions)).

(d) Seller Cooperation. Prior to Closing, Seller shall use Commercially Reasonable Efforts to provide, and cause their respective Affiliates and representatives to use Commercially Reasonable

Efforts to provide, such cooperation as may be reasonably requested by Purchaser and the Financing sources in connection with the Financing at no material cost to Seller or the Company, including, without limitation,

(iii) facilitating the granting of a security interest (and perfection thereof) in collateral, guarantees, mortgages, other definitive financing documents contemplated by any debt financing or as may be requested by the Purchaser; provided that there are no legal or contractual restrictions or impediments to such pledge or security document taking effect on the terms and conditions described therein (other than documentation relating to indebtedness to be discharged at Closing) and that no such pledge or security document shall be effective, and the Company shall have no liability under, any such document prior to Closing;

(iv) obtaining customary authorization letters with respect to the bank information memoranda or offering memoranda (as the case may be) and consents of the auditors (or reserve engineers, if applicable) for use of their reports in any such materials or other materials relating to any debt financing (including any registration statement, prospectus, offering memorandum or private placement memorandum);

(v) providing all information to the Lenders and their advisors and the Purchaser and its advisors as shall reasonably be requested in connection with legal and business due diligence, including obtaining accountants’ comfort letters, legal opinions, and other customary information or documents as reasonably requested by the Purchaser; provided that providing such information does not

constitute waiver of attorney-client privilege and further provided that Purchaser shall reimburse Seller for any reasonable out-of-pocket costs incurred by Seller in connection with providing such information;

(vi) providing such information to legal counsels to allow them to prepare and deliver customary 10b-5 “negative assurance” letters in connection with any offering of Securities contemplated by clause (i) above;

The Parties acknowledge that money damages would not be an adequate remedy at Law if any party fails to perform in any material respect any of its obligations hereunder and accordingly agree that each Party, in addition to any other remedy to which it may be entitled at Law, in equity or, after the Closing, as provided in this Agreement, shall be entitled to specific performance of the obligations of any other Party under this Agreement and appropriate injunctive relief may be applied for and granted in connection therewith, in each case, in accordance with Section 9.17 of this Agreement, and if any action should be brought in equity to enforce any of the provisions of this Agreement, none of the Parties shall raise the defense that there is an adequate remedy at Law. No remedy shall be exclusive of any other remedy. All available remedies shall be cumulative. Any party seeking an injunction to prevent breaches of this Agreement and to enforce specifically the terms and provisions hereof shall not be required to provide any bond or other security in connection with any such order or injunction.

9.4 Assignment. Neither this Agreement nor any of the rights, interests or obligations hereunder shall be assigned by any Party hereto without the prior written consent of the other Parties; provided that the Parties may assign this Agreement to any Affiliate without the prior written consent of the other Party. Subject to the preceding sentence, this Agreement will be binding upon, inure to the benefit of and be enforceable by, the Parties and their respective successors and permitted assigns, and is not intended to confer upon any Person other than the Parties and their respective successors and permitted assigns any rights or remedies hereunder.

9.5 Waiver. Any of the terms or conditions of this Agreement which may be lawfully waived may be waived in writing at any time by each Party which is entitled to the benefits thereof. Any waiver of any of the provisions of this Agreement by any Party hereto shall be binding only if set forth in an instrument in writing signed on behalf of such Party. No failure to enforce any provision of this Agreement shall be deemed to or shall constitute a waiver of such provision and no waiver of any of the provisions of this Agreement shall be deemed to or shall constitute a waiver of any other provision hereof (whether or not similar) nor shall such waiver constitute a continuing waiver.

9.6 Survival. The provisions of this Section 9.6 and Sections 2.1(d), 2.1(e), 2.1(h), 2.4, 5.2(b), 5.3, 5.10, 5.13, 5.17, 9.17 of this Agreement shall not merge into the various documents executed and delivered pursuant to this Agreement, but shall instead survive the Closing, subject only to any applicable statute of limitation or other express limitation herein. All other provisions of this Agreement shall merge into the documents executed and delivered pursuant to this Agreement.

(a) All Disputes Subject to Dispute Resolution Process. Any and all disputes between the Parties arising pursuant to, out of, in connection or related in any way with this Agreement and its meaning, interpretation, application, shall be resolved as set forth in Section 5.3 and this Section 9.17 (the “Disputes”).

(b) Informal Negotiation. Subject to a Party’s right to seek exigent equitable relief as provided in Section 9.17(d), before an Arbitration Notice can be provided by one Party to the other, the Parties shall first engage in informal negotiation in the effort to resolve any dispute. The informal negotiation shall be initiated by one Party providing the other a written dispute notice (the “Dispute Notice”). The Parties shall in good faith negotiate for a period of no less than ten (10) calendar days and no more than sixty (60) calendar days after receipt of the Dispute Notice. The Dispute Notice shall include (i) a brief statement of the legal and factual basis for the claim; (ii) identification of documents relevant to the claim; and, (iii) a statement of the actions demanded to resolve such claim. If these negotiations do not resolve the claim, additional good faith negotiations for up to sixty (60) calendar days shall occur between senior executives of each Party within thirty (30) calendar days of conclusion of previous informal negotiations described in this Section 9.17. For purposes of notices required under this Section 9.17, the Parties shall provide notice in accordance with the notice provisions in Section 9.7 of this Agreement.

(c) Executive Management Involvement. Nothing in this Section 9.17 is intended to prevent the executive management of the Parties from becoming involved in a Dispute(s) at any time after the Dispute Notice is delivered. If the Dispute is not thereafter resolved within sixty (60) calendar days after receipt of the Dispute Notice, or such other time period agreed to in writing by the Parties, either Party may initiate binding arbitration, as set forth below.

(d) Court Relief. Any unresolved disputes that require exigent equitable relief (including, without limitation, specific performance or injunctive relief) to preserve the status quo may be brought only in the Eleventh Judicial District Court of the State of New Mexico without the need for the aggrieved Party to first submit to or complete a binding arbitration, but only if injunctive or other equitable relief is so needed before arbitration can feasibly be commenced and an arbitrator can be appointed and hear the matter, and only for equitable relief (such as specific performance or injunctive relief) in accordance with the terms of this Agreement.

(e) Binding Arbitration. In the event negotiations between the Parties do not result in resolution of the Dispute(s), the Parties shall submit to binding arbitration conducted pursuant to the American Arbitration Association’s (“AAA”) Commercial Arbitration Rules, including Procedures for Large, Complex Commercial Disputes and the Optional Rules for Emergency Measures of Protection, all as may be amended from time to time (collectively “AAA Rules”), except as otherwise provided herein, and the New Mexico Uniform Arbitration Act, Section 44-7A-1 through Section 4-7A-32with substantive resolution of any Disputes governed by the choice of law provided in Section 9.17(g) of this Agreement, subject to and conditioned by the following:

The Arbitration Notice shall be provided to the Respondent in accordance with the Notice provisions of Sections 9.7 and 9.17(b).

(ii) Response to Arbitration Notice. Within thirty (30) calendar days of receipt of the Arbitration Notice (unless otherwise agreed to in writing by the Parties), the Respondent shall provide the Claimant a Response to the Arbitration Notice, which shall include: (i) the designation of such Party’s arbitrator; and (ii) a reasonably detailed statement of the facts and theories supporting the Respondent’s defenses and counter-claims. Neither the Arbitration Notice, nor the Response may seek the joinder of other entities to the arbitration proceeding or otherwise seek to consolidate any arbitration proceedings under this Agreement with any other arbitration or judicial proceedings, unless otherwise agreed by the Parties. The Parties agree that any arbitration shall only be binding as between the Parties.

(iii) Third Neutral Arbitrator. The two (2) Party arbitrators shall choose the third neutral arbitrator for the arbitration panel. In the event the two (2) Party arbitrators cannot agree on a third neutral arbitrator, the AAA shall select a third neutral arbitrator from its National Roster, who shall be free of any association of any kind with either Party, and whose participation as an arbitrator shall not otherwise constitute a conflict of interest or give rise to an appearance of impropriety.

(iv) Arbitrator Requirements. All arbitrators shall be competent and professionally experienced in the technical and/or legal matters in dispute in the arbitration. The Parties agree that none of the arbitrators shall be employees, advisors, stockholders, or bondholders of the Parties or any of their affiliates, or any organization affiliated with the Parties’ entities or their affiliates. All

arbitrators shall be selected, and shall conduct themselves in accordance with Canon IX of the American Bar Association’s Code of Ethics for Arbitrators in Commercial Disputes, as amended.

(v) Schedule.

(vii) Discovery. Deposition and written discovery shall be reasonably limited by the arbitrators to achieve economical resolution of the dispute. Except in exceptional circumstances, or by mutual agreement of the Parties, and without restricting the arbitrators’ authority to further limit discovery, one set of not more than thirty (30) interrogatories and one set of not more than twenty (20) document requests, depositions of opposing expert witnesses, and no more than five (5) depositions of non-expert witnesses per Party shall be deemed adequate. The arbitrators shall have the authority to issue orders to effectuate such discovery consistent with the AAA Rules, and where appropriate, the Federal Rules of Civil Procedure.

(viii) Location. The arbitration shall be conducted at a mutually-agreed-upon location; which shall be any of the following cities: Farmington, New Mexico and Albuquerque, New Mexico. In the event the Parties cannot agree to the location of the arbitration hearing or proceeding, a majority of the arbitral panel shall decide on the location of the arbitration hearing or proceeding; which shall be any of the following cities: Farmington, New Mexico; and Albuquerque, New Mexico.

In any arbitration, each Party shall bear its own costs, expenses, and attorneys' fees. The arbitrators do not have authority to award costs, expenses, or attorneys' fees to the prevailing Party. The Party-appointed arbitrators’ fees and expenses shall be paid by the appointing Party. The Parties shall split, and pay, the third neutral arbitrator’s fees and expenses equally.

(xi) Award and Enforcement. The decision or award of the arbitration panel shall be made by a majority of the panel, and given in writing to the Parties within thirty (30) calendar days after the conclusion of the arbitral hearing or proceeding, the submittal of any post-hearing briefs or other filings that may be requested by the arbitration panel.
