WHEREAS, pursuant to the Case, Westmoreland San Juan Mining, LLC (“WSJM”) is the successor in interest to SJCC’s obligations under the Agreement; and

WHEREAS, Guarantor is willing to guarantee WSJM’s performance of its obligations under the Agreement;

NOW, THEREFORE, for good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, Guarantor hereby agrees with Utility as follows:

1.1Effective as of the Effective Date (as that term is defined in the Agreement), Guarantor hereby unconditionally and absolutely guaranties to Utility and its successors and permitted assigns timely and complete payment and performance of all of WSJM’s obligations under the Agreement and all other present or future agreements and instruments between Utility and Contractors in connection with the performance of the Agreement (all of the foregoing the “Agreement Documents”), all whether presently existing or from time to time hereafter created, incurred or arising and including, without limitation, any interest accrued on such amounts pursuant to the Agreement Documents (such obligations of WSJM collectively the “Obligations”). This Guaranty is a continuing guarantee, and shall apply to all Obligations whenever arising.

1.2Guarantor hereby agrees that its obligations hereunder shall be absolute and unconditional irrespective of (i) any insolvency, bankruptcy, reorganization or dissolution, or any proceeding in respect of any thereof, of WSJM or Guarantor, (ii) the validity, regularity or enforceability (except to the extent that the Agreement would not have been enforceable against Guarantor had it, rather than WSJM, been the primary obligor thereunder) of obligations of WSJM under the Agreement or the extension or renewal thereof, in whole or in part, with or without notice to or assent from Guarantor, (iii) any alteration, amendment, modification, extension, renewal, release, change, waiver or consent in respect of any of the terms, covenants, or conditions contained in the Agreement, and

Guarantor acknowledges and agrees that its consent to any of the foregoing actions is not required, or (iv) the absence of notice, other than notice required by the terms of the Agreement, or the absence of or any delay in any action to enforce any obligation or to exercise any right or remedy against WSJM or Guarantor, whether hereunder or under the Agreement, or any indulgence or extension granted to or compromise with WSJM or Guarantor, or any action or proceedings taken or not taken with respect to or by or on behalf of SJCC WSJM or Guarantor or (v) any circumstance whatsoever (including, without limitation, any statute of limitations) or any act of the Utility or any existence of or reliance on any representation by the Utility that might otherwise constitute a legal or equitable defense available to, or a discharge of, the Guarantor.

1.3Guarantor hereby (i) waives diligence, presentment, demand of payment, filing of claims with a court in the event of the merger or bankruptcy of WSJM, any right to require a proceeding first against WSJM, or to realize on any collateral, protest, notice and all demands whatsoever, with respect to the obligations of WSJM, (ii) agrees that its obligations hereunder constitute guaranties of performance and not of collection and are not in any way conditional or contingent upon any attempt to collect from or enforce against WSJM or upon any other condition or contingency, (iii) agrees that its obligations hereunder shall continue to be effective if at any time the obligations of WSJM under the Agreement are rescinded or modified or limited in connection with any bankruptcy or reorganization or other similar proceedings, and (iv) covenants that this Guaranty will not be discharged except by complete performance of WSJM’s obligations under and contained in the Agreement. Without limiting the generality of the preceding clause (ii), Guarantor specifically agrees that it shall not be necessary or required and that it shall not be entitled to require that Utility or either of them file suit or proceed to obtain or assert a claim for any judgment against WSJM or make any effort to enforce the Agreement or exercise or assert any other right or remedy to which Utility or either of them is or may be entitled in connection with the Agreement or any security or Guaranty or assert or file any claim against the assets of WSJM or any other person before or as a condition of enforcing the liability of Guarantor under this Guaranty or at any time thereafter

2.1This Guaranty is made to Utility solely for its benefit and may not be assigned by Utility except in connection with and contemporaneously with an assignment of the Agreement as permitted therein, and any other purported assignment shall be void and of no force and effect.

2.2Guarantor agrees that it will maintain its corporate existence, will not dissolve or otherwise dispose of all or substantially all of its assets and will not consolidate with or merge into another corporation; provided, however, that Guarantor may consolidate with or merge into, or sell or otherwise transfer all or substantially all of its assets as an entirety (and may thereafter dissolve) to, another corporation incorporated and existing under the laws of the United States or one of the states thereof, provided that, in the event that Guarantor is not the surviving, resulting or transferee corporation, as the case may be, such corporation, prior to such merger, consolidation, sale or transfer, assumes, by delivering to Utility an instrument in writing satisfactory in form and substance to Utility, all of the obligations of Guarantor herein.

2.3No remedy herein conferred upon Utility is intended to be exclusive of any other available remedy or remedies, but each and every such remedy shall be cumulative and shall be in addition to every other remedy given under this Guaranty or now or hereafter existing at law or in equity.

2.4The obligations of Guarantor hereunder shall be continuing and irrevocable. This Guaranty constitutes the entire agreement and supersedes all prior agreements and understandings both written and oral among Guarantor and Utility with respect to the subject matter hereof. No modification or waiver of this Guaranty shall be binding upon Utility or Guarantor unless such modification or waiver shall be in writing and signed by an officer of each of Utility and of Guarantor.

2.5This Guaranty shall be construed in accordance with and governed by the laws of the State of New Mexico. Wherever possible each provision of this Guaranty shall be interpreted in such manner as to be effective and valid under applicable law, but if any provision of this Guaranty shall be prohibited by or invalid under such law, such provisions shall be ineffective only to the extent of such prohibition or invalidity, without invalidating the remainder of such provision or the remaining provisions of this Guaranty. THE GUARANTOR HEREBY IRREVOCABLY WAIVES ALL RIGHT TO TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM (WHETHER BASED ON CONTRACT, TORT OR OTHERWISE) ARISING OUT OF OR RELATING TO, THIS GUARANTY, OR THE ACTIONS OF THE BENEFICIARY IN THE NEGOTIATION, ADMINISTRATION, PERFORMANCE OR ENFORCEMENT THEREOF.

2.6Each and every default of WSJM in performance of any obligation under the Agreement shall give rise to a separate cause of action hereunder, and separate suits may, but need not, be brought hereunder as each claim or cause of action arises.

2.7All payments by Guarantor to Utility shall be made in United States Dollars to the account designated by Utility and shall be paid within fifteen (15) days after receipt by Guarantor from Utility of written demand for such payment and shall not be the subject of any offset against any amounts which may be owed by Utility to Guarantor.

2.8Guarantor agrees to pay all costs, expenses and fees, including all reasonable attorneys’ fees, which may be incurred by Utility in enforcing this Guaranty, whether by suit or otherwise, to the extent Utility is the prevailing party.
