Contractor shall develop and shall recommend to Owner a strategy for negotiation of all amendments, renewals or other modifications to such permits or bonds as may be necessary to allow Contractor to complete the Work. Owner will implement such strategy in cooperation with Contractor unless such strategy is, in Owner's reasonable judgment, inconsistent with applicable law, regulation or administrative policy or the terms of this Agreement, such strategy jeopardizes the continued existence of such permits or bonds, or such strategy will subject Owner to penalties under such law, regulation, policy, permits or bonds. To the extent permitted by applicable law, regulation and administrative policy and so long as such direction is consistent with the preceding sentence, Contractor will prepare all correspondence, drawings and other documents related to, and will direct the course of all negotiations with such agencies and businesses with respect to the terms, conditions, renewals, amendments, extensions, replacement or transfer of such permits and bonds; provided, however, that Owner will initiate all contacts with the agencies or businesses involved and will participate in all meetings and telephone conferences or other conversations with such agencies and businesses and will approve in advance the form and content of all correspondence and other documents prepared by Contractor in connection with such negotiations prior to submission to such agencies and businesses. (f) Contractor shall also promptly develop a strategy with respect to, and advise Owner as to, any additional permit or bond or increase in the amount of an existing bond that is or will be required with respect to the Work.

Contractor 7 EXHIBIT 10.52 further acknowledges that Contractor has familiarized itself with all laws and regulations applicable to the performance of the Work, including in particular all laws and regulations pertaining to the NRC that might be applicable to the Sweetwater Mill and the Work. By execution of this Agreement, Contractor acknowledges such visit and an understanding of all circumstances and conditions under which the Work must be accomplished. Contractor shall have the sole responsibility of satisfying itself concerning the nature and location of the Work and the general and local conditions. (c) Any prior work, investigations or studies made by Owner with respect to the Sweetwater Mill or the Work which are made available to Contractor by Owner were made by Owner solely with respect to its decision to proceed with the Work and were made only for the purpose of study and design. The records of such work, investigations or studies are not a part of this Agreement and are furnished solely for the convenience of Contractor and Contractor acknowledges that its agreement to enter into this Agreement is in no way premised upon the scope, completeness or accuracy of such work, investigations or studies. Owner makes no warranty, and assumes no responsibility whatsoever, in respect to the sufficiency or accuracy of the work, investigations or studies thus made. 2.9 Contractor's Warranty. (a) Contractor warrants and guarantees that the Work shall be performed with that degree of skill and judgment which is normally exercised by recognized professional consulting (including environmental consulting), engineering, procurement and construction management firms performing services of a similar nature taking into account the oversight responsibilities of the NRC and other affected agencies with respect to portions of the Work, and shall be free of faulty planning, consulting, engineering, design, procurement, construction management and quality assurance, field engineering and other services of Contractor, and that the Work shall be performed and shall conform to generally accepted consulting, engineering and construction management standards and practices. (b) Contractor's liability for breach of the warranty and guarantee given in this paragraph or the negligent performance of the Work to be performed hereunder by Contractor, its subcontractors or their employees shall be as follows: (i) Contractor, upon receipt of notice from Owner, shall promptly remedy the defect or damage identified by Owner through reperformance of the work and/or repair or replacement of the facility so identified; (ii) If Contractor is unable to so remedy the defect or damage to the satisfaction of Owner promptly, or if Contractor elects not to perform such remedy, Owner shall have the right to reperform the work and/or repair or replace the facility; and (iii) The cost of any work necessary to remedy the defect or damage resulting from Contractor's breach of the warranty and guarantee given in this section or the misconduct, error or omission or negligent performance of the Work shall be to Contractor's account, and Contractor shall not be 8 EXHIBIT 10.52 entitled to any fee, overhead expense, general or administrative expense in connection with such remedy. For purposes of calculating KUC's contributions to the Green Mountain Mining Venture as provided in Section 3 of the GMMV Amendment, each dollar contributed by KUC will count against KUC's obligation pursuant to Subsection 3(a) and each such dollar will be treated as a two dollar contribution for purposes of Subsection 3(b) of the amendment; or (iv) Owner may exercise any of its other rights and remedies as provided in this Agreement. 2.10 Back Charges. In addition to the rights and obligations attendant to the Contractor's warranty in Section 2.9 above, Owner shall have the following rights and Contractor the following obligations: (a) In the event any aspect of the Work performed by Contractor or its subcontractors under this Agreement is found to be defective as to workmanship or not to be in conformance with plans, specifications or NRC or other agency requirements, it remains the responsibility of Contractor to promptly correct any deficiency when so directed. (b) If upon being notified by Owner of deficient Work and having been directed to correct the deficient Work by a specific date consistent with the current project schedule, Contractor states, or by its action indicates to Owner, its inability or unwillingness to comply, then Owner shall have the right to suspend further Work by Contractor pursuant to Section 2.19 of this Agreement and to proceed to have the Work accomplished by the best and/or most expeditious means available to Owner (as determined by it, in its sole discretion) and back charge Contractor for the cost of the Work undertaken by Owner. For purposes of calculating KUC's contributions to the Green Mountain Mining Venture as provided in Section 3 of the GMMV Amendment, each back charged dollar will count against KUC's obligation pursuant to Subsection 3(a) and each back charged dollar will be treated as a two dollar contribution for purposes of Subsection 3(b) of the amendment. (c) Before proceeding on such back charge work, Owner will advise Contractor and forward to Contractor an Authorization of Back Charge for Contractor's signature. However, failure of Contractor to provide such written authorization shall not impair Owner's right to proceed to have the work performed and charge Contractor therefor. Contractor shall pay actual costs incurred, computed as shown above, or Owner may withhold such sum from funds due Contractor. The performance of back charge work shall not relieve Contractor of any of its responsibilities under this Contract, including but not limited to, express or implied warranties, guarantees, specified standards for quality, liabilities and indemnification, and the Contract schedule. 9 EXHIBIT 10.52 2.11 Indemnification. Contractor agrees to indemnify, defend, release and hold harmless the Indemnified Parties from and against the entirety of any and all Adverse Consequences, whether arising during or after the term of this Agreement, any of them shall suffer: (a) As the result of any breach of any obligation, representation, covenant or warranty of Contractor or its subcontractors as set forth in this Agreement; (b) As the result of (i) the release, threatened release, discharge, storage, treatment, disposal or presence of Hazardous Materials at, upon, about or beneath the Sweetwater Mill as a result of Contractor's operations; (ii) the release, threatened release, or discharge of Hazardous Materials emanating or migrating, or threatening to emanate or migrate to, from or across Owner's properties arising out of Contractor's or its subcontractors' operations; (iii) any violation of any Environmental Laws pertaining to the Sweetwater Mill and the activities thereon; or (iv) the treatment, storage, disposal, arrangement for disposal, or transportation of Hazardous Materials by Contractor at or to a facility other than one at the Sweetwater Mill; and (c) Contractor acknowledges and agrees that it has assumed the sole obligation and duty to provide a safe place to work for its employees and the employees of its subcontractors and agrees that Owner has no responsibility therefor, and that any claim for damages by employees of Contractor or its subcontractors against Owner alleging that Owner failed to furnish a safe place to work, shall not be construed as relieving Contractor of its indemnity obligations to Owner under the terms of this Agreement, except to the extent such claims for damages arise from a non-apparent pre-existing site condition, or from Owner's or its agents' (other than Contractor) negligence, willful misconduct or violation of any representations hereunder. 2.12 Waiver and Release of Liens. Contractor for itself and its subcontractors and for its and their materialmen and employees and for all other persons performing any labor or furnishing any labor or materials for any of the Work hereby waives to the full extent permitted by law all mechanics', materialmen's or other liens, or payment bond claims for or on account of the work done or materials furnished hereunder so that the improvements of structures wherein the same may be incorporated and the land to which they are appurtenant shall at all times be free and clear of all such liens and claims. If such liens or claims are placed on Owner's property by any person performing any labor or furnishing any labor or materials for any of the Work, Contractor will promptly have such liens or claims removed at Contractor's expense and Contractor shall indemnify Owner from any liabilities associated with such lien. 2.13 Owner-Furnished Materials, Tools and Equipment. In the event Owner furnishes materials or equipment for use on or with respect to the Work, Contractor shall be solely responsible for inspecting and using the same and for protection thereof from loss, damage of any kind and for payment of any demurrage incurred. 10 EXHIBIT 10.52 2.14 Contractor's Security Responsibilities. Contractor shall at all times conduct all operations under this Agreement in a manner to avoid the risk of loss, theft, or damage by vandalism, sabotage, or other means to any property. (a) Contractor shall promptly take all reasonable precautions which are necessary and adequate against any conditions which involve a risk of a loss, theft, or damage to property. Contractor shall continuously inspect all work, materials, equipment, and facilities to discover and determine any such conditions, and shall be solely responsible for discovery, determination, and correction of any such conditions; (b) Contractor shall ensure compliance by the employees of Contractor and all subcontractors with Owner's security program for this site and all applicable laws and regulations. Contractor shall cooperate with Owner on all security matters and shall promptly comply with any project security requirements established by Owner. In particular, Contractor agrees that all vehicles that enter upon Owner's property, and all lunch, other containers, and packages of Contractor, its subcontractors and their employees, shall be subject to inspection by Owner's security personnel at any time while on Owner's property; (c) Owner will accept no responsibility for replacement of, protection to, or policing of, Contractor's equipment, tools, or materials which are furnished or used in its work at Owner's property; and (d) Contractor shall, at its own expense, replace any lost or stolen property, repair any damage to all property of whatever kind or character, whether publicly or privately owned, including the property of Owner, which may result from its operations under this Contract. 2.15 Inspection of Work. (a) Owner shall at any and all times have access to the Work and to the premises affected thereby and to all equipment and materials, and to related books, records, correspondence, instruction plans, drawings, receipts, facilities, and memoranda of Contractor for inspection purposes including the utilization at Owner's expense of third-party inspectors; and Contractor shall provide proper facilities for such access and inspection. (b) Owner shall at all times remain the primary contact with any regulatory agency for which Owner is the permittee or licensee and shall have the sole responsibility for determining through inspection of the Work and consultation with Contractor when, and under what circumstances, drawings, specifications, correspondence and the like shall be submitted to such agencies. Contractor shall not initiate any contact with such agencies except as expressly provided in this Agreement. 2.16 Cooperation. Owner may perform work, including the normal operations of Owner, in the vicinity of or on the premises affected by the Work, and Contractor's work or use of certain facilities may 11 EXHIBIT 10.52 be interfered with as a result of such concurrent activities. Owner will cooperate with Contractor so that Contractor may perform the Work as required by this Agreement and Contractor will cooperate in scheduling the Work in such a manner as will minimize interference with any work being undertaken by Owner. 2.17 Progress. (a) Contractor will provide to Owner a program, in reasonable detail, of the operations and activities that Contractor expects to undertake in progressing to accomplish Phase I of the Work in the ensuing calendar quarter. The program will be submitted to Owner at least 15 days prior to the commencement of any such operations or activities. Within 30 days after the end of each calendar quarter, Contractor will submit to Owner a report, in reasonable detail, that describes the operations and activities that were actually undertaken in the calendar quarter and any activities described in the program that were not undertaken and accomplished. (b) Contractor will not undertake any operations or activities that depart from Phase I of the Work or the operations and activities set out in the program without submitting to Owner a proposed amendment to the program that describes such amended operations and activities and, if such amendment would require a modification of Phase I of the Work as described in Appendix A, a proposed amendment to the Work. Within 20 days of any such proposal, Owner will notify Contractor of its acceptance or rejection or the proposed amendment, which acceptance will not be unreasonably withheld so long as the proposed amendment does not depart from the overall scope of the Work and is consistent with the other terms and provisions of this Agreement. With respect to any proposal for modification of the program prepared by Contractor or any proposal to modify Phase I of the Work that departs from the overall scope of Work as described in Appendix A, Owner may accept or reject such proposal at Owner's sole discretion. (c) Contractor will not undertake any operations or activities with respect to Phase II of the Work until Contractor has developed, and Owner has approved, a detailed description of the Work to be accomplished in Phase II. Upon receipt of Owner's approval, Contractor may commence operation and activities with respect to Phase II by submitting a program as provided in Subsection 2.17(a). Owners response to that proposal and any proposed amendments to Phase II of the Work will be governed by the provisions of Subsections 2.17(a) and 2.17(b). 2.18 Force Majeure. Except as provided in Subsections 2.18(b) or 2.18(c) below, the failure to perform or to comply with any of the covenants or conditions contained in this Agreement, either expressed or implied, on the part of either party shall not be a ground for cancellation or termination or forfeiture of this Agreement, and shall not create a liability for the party for failure to perform its obligations during any period in which performance is prevented, in whole or part, by causes herein termed "force majeure". (a) For purposes of this Agreement, the term "force majeure" shall be limited to substantial and unforeseeable events beyond the control of a party that cannot be avoided through the diligent actions of a party, including extreme weather conditions; earthquakes or cave-ins; unforeseeable unavailability of labor, transportation, materials, machinery, equipment, supplies, 12 EXHIBIT 10.52 utilities, or services even on premium terms; serious accidents; unavoidable breakdown of major equipment, machinery, or facilities; injunctions issued by any court; inability to obtain licenses, permits, or other authorizations in spite of diligent efforts to do so; curtailment or suspension of activities to remedy or avoid an actual, serious violation of environmental laws; acts of war or conditions arising out of or attributable to war; riot; civil strife; fire; explosion; or any similar cause beyond the reasonable control of the party declaring force majeure. (b) If either party desires to invoke the provisions of this Section 2.18, the invoking party shall give notice to the other party of the commencement of the circumstances giving rise to such force majeure. The time for discharging the party's obligations with respect to the prevented performance shall be extended for the period of force majeure, provided that the party invoking force majeure pursues diligent efforts to eliminate the event that gave rise to the condition of force majeure. The existence of any event of force majeure shall not relieve a party of the obligation to make any payments required of a party with respect to maintenance of the Sweetwater Mill and the permits and bonds associated with the properties in accordance with the terms of this Agreement, making payments due under Section 3 of this Agreement and carrying out the indemnities required by Section 2.11, nor shall an event of force majeure extend the term of this Agreement. If an event of force majeure prohibits performance by Contractor, but would not prohibit performance by the Owner, for more than 120 days, Owner may terminate this Agreement for convenience and will have no further obligation to Contractor hereunder. (c) Notwithstanding the foregoing, neither party may invoke force majeure with respect to any event that would otherwise constitute force majeure if the duration of such event is less than 15 days. 2.19 Suspension.
