Unless agreed otherwise by the Parties,  Change Orders which result in additional or reduced payments to Contractor shall result in an equivalent upward or downward adjustment to the Contract Price, as the case may be.

			
	
			
				 (i)
			Company shall have the right to exercise the option to purchase certain additional equipment, material and/or services which as of the Effective Date are not included as part of the Work and which are described in Appendix E (the “Option”), within the times frame and at the price stated therein.  If Company exercises the Option in writing prior to the Option exercise deadline set forth in Appendix E, the Contract Price will be adjusted upward to account for the price associated with the Option and the equipment, materials and/or services associated with the Option shall become part of the Work.  The specific payment, construction and/or delivery schedules associated with such Option shall be set forth in a mutually agreed upon Change Order.

			
	
			
				 (b)
			Company shall pay Contractor all undisputed invoice amounts in accordance with the Payment Schedule within twenty-five (25) days of receipt of an invoice from Contractor; provided, however, in no event shall any payment be due and owing until such time as the Work associated with the applicable Payment Milestone has been satisfactorily completed and accepted by Company pursuant to the procedures set forth in this Contract (including Appendix D) and all other conditions to payment have been satisfied. Notwithstanding the foregoing, in the case of payments to be made pursuant to Payment Milestones,  no payment shall be made thirty (30) days prior to the Milestone Date corresponding to the applicable Payment Milestone unless Contractor (i) has achieved the Payment Milestone for which payment is requested and due in accordance with the Payment Schedule, and (ii) all Milestones for which Contractor has submitted a Notice of Request for Payment prior to such Payment Milestone have been achieved prior to Contractor submitting its invoice with respect thereto.  Payment due dates shall be on Business Days. If any payment becomes payable on a day that is not a Business Day, then payment shall be paid on the next succeeding Business Day. Company shall pay interest on any late payments, including any payment amount which Company disputes in good faith and which is later found conclusively to be have been due, at the Late Payment Rate, compounded daily from the date such amount was due.

If Company’s Representative disputes only a portion of the invoiced amount, the remaining amount not in dispute shall be paid on or before the due date. 

			
	
			
				 (e)
			Notwithstanding Section 3.1(d), payment by Company of any invoiced amounts shall not be deemed acceptance of the Work or waiver of any Claims that Company may have with respect to such Work,  including with respect to the completeness thereof or the compliance of such Work with Applicable Law or the terms of this Contract.

			
	
			
				 (f)
			In addition to the foregoing, within five (5) Business Days after receipt by Contractor of any payment made pursuant to (i) the Payment Schedule and/or (ii) any Limited Notice to Proceed, Contractor shall deliver to Company the Retainage Letter of Credit pursuant to Section 6.1(b).    

			
	
			
				 Section 3.2
			

			
	
			
			Conditions Precedent to Payment of Invoiced Amounts

		
			The obligation of Company to make payments for any invoice is subject to the satisfaction or waiver by Company of each of the following conditions precedent on each Milestone corresponding to the applicable Payment Milestone for which payment is being sought pursuant to the Payment Schedule:

				 (b)
			Representations and Warranties.   The representations and warranties made by Contractor in each Project Document to which it is a party shall be true and correct in all material respects on such payment date both before and after giving effect to the making of such payment. In each case such representations and warranties shall be deemed renewed and re-stated as of the date of such payment.

			No Change shall be effective unless authorized by Company by issuance of a Change Order pursuant to the provisions of this Article 13.

			
	
			
				 (c)
			Company shall, when reviewing each Contractor-Proposed Change and determining the nature and extent of any Change Order issued in accordance with this Article 13, consider in detail the following information:

			the factors necessitating or the basis for the proposed Change;

			
	
			
				 (ii)
			The nature, scope and extent of the Change,  including any additions to or deletions from the Work;

				 (iii)
			The effect, if any, of the Change on the Project Schedule, any Critical Milestone, the Guaranteed Substantial Completion Date or the completion of any Final Punch List items, as applicable;

			
	
			
				 (iv)
			The effect, if any, of the Change on the amount of the Contract Price; and

			
	
			
				 (v)
			Such other information as may reasonably be necessary for the implementation of the Change Order,  including the effect on any other provisions of this Contract.

			
	
			
				 (d)
			All requests for a Change Order shall be made in a form substantially similar to the form attached hereto as Exhibit O which shall address, to the extent required, all of the matters applicable to such request under this Article 13 (each, a “Change Order Request”). Company shall, in the case of a Company-Proposed Change or, if it elects to do so, in the case of a Contractor-Proposed Change, and in all events in the case of a Required Change, thereafter issue a Change Order substantially similar to the form attached hereto as Exhibit P, which shall be signed by both Parties.

			
	
			
				 (e)
			If Company desires to request a Company-Proposed Change, it shall communicate in writing to Contractor via a Change Order Request its requested Change.  Contractor shall promptly review the Company’s Change Order Request and shall notify Company in writing within ten (10) days after receipt of the options for implementing the proposed Change (including, if possible, any option that does not involve an increase in the Contract Price or extension of the Project Schedule), and the effect, if any, each such option would have on the Contract Price or the Project Schedule.  After consideration of such information from Contractor, Company may, but shall not be obligated to, issue a Change Order in accordance with the option the Company selects.  For the avoidance of doubt, Contractor shall be required to implement any and all Company-Proposed Changes if Company elects to proceed with such any such Change (subject to Section 13.2).

			
	
			
				 (f)
			If Contractor (i) desires to request a Contractor-Proposed Change or (ii) believes a Required Change is warranted, it shall in either case communicate in writing to Company via a Change Order Request the Contractor-Proposed Change or Required Change.  Any request by Contractor for a Change Order under this Section 13.1(f) shall be delivered to Company in writing as soon as reasonably practicable and in any event within ten (10) days after Contractor becomes aware of the circumstances which it believes necessitates or warrants a Change. In no case shall Contractor be entitled to recover Costs via a Change Order in connection with conditions that give rise to such Change Order arising prior to the date on which Contractor submits the Change Order Request, except as otherwise included in an agreed-upon Change Order.

			Contractor shall be entitled to the issuance of Change Orders pursuant to this Article 13 in connection with any circumstances which constitute a Required Change; provided that Contractor shall have in all cases use or have used commercially reasonable efforts to mitigate potential delays to the Project Schedule and potential

			increases to the Contract Price (the cost of such mitigation efforts to be addressed in any applicable Change Order).

			
	
			
				 (h)
			No circumstances will constitute grounds for a Change Order unless and to the extent that the Costs of such Change Order are in excess of Three Thousand Dollars ($3,000).   The foregoing limitation shall not apply to the extent that the activities that are the subject of separate Change Orders, one or more of which is below Three Thousand Dollars ($3,000), would, consistent with Prudent Industry Practices, the nature of the activities and the events giving rise to such Change Orders, have been the subject of a single Change Order.  

			
	
			
				 (i)
			Unless agreed otherwise by the Parties, the amount of a Change Order shall be equal to (i) the Costs of Contractor (labor, materials, and out-of-pocket expenses, etc.) to perform the work associated with the Change, plus (ii) a fee to be agreed upon by the Parties, plus (iii) solely in the case of a Company-Proposed Change, the Costs incurred by Contractor in preparing an estimate or proposal in connection with the work associated with such Change, which Costs shall be reimbursed by Company to Contractor without regard to whether the Company-Proposed Change results in a Change Order.  Any such amounts that are paid on a cost reimbursable basis will be subject to audit by Company upon reasonable prior notice except for the fee portion thereof.  

			
	
			
				 Section 13.2
			

			
	
			
			Continued Performance Pending Resolution of Disputes

		
			If the Parties are in dispute on a request for a Change Order,  Contractor shall, pending resolution of such dispute, nevertheless continue to perform work per the Change Order if it is a Change Order pursuant to a Required Change or Company-Proposed Change, unless Company directs Contractor not to proceed and provided that Contractor has been paid on a current basis for undisputed Work and for disputed Work which has been ordered to be paid through the dispute resolution procedures of this Contract.  
		

			
	
			
				 Section 13.3
			

			
	
			
			Preservation of Schedule and Contract Price

		
			Where any proposed Change or Change Order Request may give rise to an extension of any of the Project Schedule or an increase in the Contract Price,  Company reserves, in its sole discretion and to the extent reasonably practicable, the right to require Contractor to vary, amend or effect such other Change to the Work in such a manner as will mitigate or avoid the requirement for such extension of time or increase in price.

LIQUIDATED DAMAGES 

			
	
			
				 Section 23.1
			

			
	
			
			General

		
			The Parties agree that it is difficult or impossible to determine with precision the amount of damages that would be incurred by Company as a result of Contractor’s failure to timely achieve Substantial Completion or to achieve the BOP Load Guarantee. Accordingly, any sums that may become payable under this Article 23 because of such failures shall be deemed (i) to be liquidated damages (“Liquidated Damages”), (ii) to not be  a penalty, and (iii) to be fair and reasonable and that they represent a reasonable estimate of fair compensation for the losses and Liabilities that may reasonably be anticipated from such failures.  Except in connection with Contractor’s obligation to meet the Minimum Performance Guarantees and the remedies associated with Contractor’s failure to do so, the payment by Contractor to Company of Late Substantial Completion LDs and BOP Load Guarantee LDs shall be Company’s exclusive remedies for and Contractor’s sole obligations arising out of such delay and/or deficiencies.
		

			
	
			
				 Section 23.2

				 (a)
			If the Work fails to achieve the BOP Load Guarantee, Contractor shall pay Liquidated Damages in accordance with this Section 23.3 (the “BOP Load Guarantee LDs”).

			
	
			
				 (b)
			If Substantial Completion has occurred and the BOP Load Guarantee has not been met at Substantial Completion as demonstrated by the Final Performance Test Report, Contractor shall have the opportunity to demonstrate to Company via technical demonstration that the BOP Load falls within a reasonably expected range and that the Plant was designed in accordance with Prudent Industry Practice and in the best interests of the Company.  If Company determines in its sole discretion that either or both of the items in the preceding sentence have not been met, Contractor shall have a sixty (60) day cure period (the “BOP Load Guarantee LD Cure Period”) after the Substantial Completion Date to either repair or replace the underperforming Equipment or otherwise remedy the failure to meet the BOP Load Guarantee, or pay to Company the BOP Load Guarantee LDs, all in accordance with Section 23.3(c).  

			
	
			
				 (c)
			Contractor shall use commercially reasonable efforts to repair or replace the underperforming Equipment, or otherwise remedy the failure to meet the BOP Load Guarantee, during the BOP Load Guarantee LD Cure Period.  On or before the expiration of BOP Load Guarantee LD Cure Period, Contractor shall have demonstrated to Company’s satisfaction in Company’s sole discretion that the BOP Load Guarantee has been met.  In the event of Contractor’s failure to so demonstrate, Contractor shall pay to Company Liquidated Damages in the amount of $1,800 per kW; provided, however, that the amount of BOP Load Guarantee LDs shall not exceed, in the aggregate, an amount equal to ten percent (10%) of the Contract Price.

Company shall have the right to audit such calculations. Contractor shall itemize such calculations and such calculations shall include such supporting documentation as Company shall reasonably request and shall be in sufficient detail to permit Company to verify each calculation. Company shall notify Contractor as soon as reasonably practicable of any portion of the calculations with which Company disagrees.  In the event Contractor disputes in good faith the payment of any portion of Liquidated Damages hereunder, Company shall not otherwise withhold payment or make payment of such disputed portion of Liquidated Damages one of the criteria for Substantial Completion.

FORCE MAJEURE

			
	
			
				 Section 27.1
			

			
	
			
			Effect of Force Majeure

		
			Neither Party shall be considered to be in default or in breach of its obligations under this Contract to the extent that performance of such obligations is prevented by any event of Force Majeure arising after the Effective Date and such Party has otherwise complied with the requirements of this Article 27.    
		

			
	
			
				 Section 27.2
			

			
	
			
			Notice of Occurrence

		
			If either Party considers that any event of Force Majeure has occurred which may materially affect performance of its obligations under this Contract, it shall promptly notify the other Party thereof stating the full particulars and anticipated duration of the event and the performance obligations that will be affected by the event.  The Party invoking Force Majeure shall provide to the other Party (i) notice of the occurrence of Force Majeure in writing within two (2) Business Days after such Party becomes aware of the occurrence and (ii) an initial written report of the potential impact of the Force Majeure event on the Work, the status of the Force Majeure event and the steps and measures undertaken or proposed to be undertaken by Contractor in connection therewith within seven (7) Business Days after the provision of the notice specified in subsection (i) and shall continue to furnish such reports on weekly basis with

		respect thereto during the continuation, and until the termination, of the Force Majeure.  Failure to provide the notice or initial report within the time periods specified in this Section 27.2, shall preclude such Party from invoking Force Majeure with respect to such event or occurrence unless there is no adverse effect or undue prejudice on the other Party as the result of any such delay.  For the avoidance of doubt, except with respect to Company-Procured Equipment,  if any Subcontractor is entitled under any contract or agreement relating to the Work to excused performance on the basis of force majeure on terms additional to or broader than those set forth in this Contract, such additional or broader force majeure events shall not excuse Contractor’s non-performance of its obligations under this Contract.

			Performance to Continue

		
			Upon the occurrence of any event of Force Majeure, Contractor shall use commercially reasonable efforts to continue to perform its obligations under this Contract, and the suspension of performance shall be of no greater scope or of no longer duration than is reasonably required by the Force Majeure. Contractor shall notify Company of the steps Contractor proposes to take, including any reasonable alternative means for performance, which is not prevented by Force Majeure. Contractor shall not take any such alternative steps unless directed to do so by Company pursuant to a Change Order.  Contractor shall use commercially reasonable efforts to (a) mitigate all such costs and impacts on the Project Schedule and (b) remedy its inability to perform and resume its performance at the earliest practical time after cessation of the Force Majeure.  The obligations of Contractor that arose prior to the Force Majeure and that are not affected by such Force Majeure shall not be excused as a result of such Force Majeure.    
		

			
	
			
				 Section 27.4
			

			
	
			
			Resumption of Performance

		
			When the Party invoking Force Majeure is able to resume performance of its obligations hereunder, that Party will provide the other Party with written notice to that effect and will promptly resume such performance.
		

			
	
			
				 Section 27.5
			

			
	
			
			Termination in Consequence of Force Majeure

		
			If circumstances of Force Majeure have occurred that have materially affected the Work and have continued for a period of forty-five (45) days in the aggregate, and there is a corresponding delay in the schedule for performance and the Guaranteed Substantial Completion Date of forty-five (45) days in the aggregate caused by the Force Majeure, then, notwithstanding that Contractor may by reason thereof have been granted an extension of the schedule for performance and the Guaranteed Substantial Completion Date by Change Order,  Company shall be entitled to provide notice of its intent to terminate this Contract upon thirty (30) days notice to Contractor. If, at the expiration of such thirty (30)-day period, such Force Majeure shall still continue, Company may elect to terminate this Contract as a Voluntary Termination.

			4.1.7General Approach
		

		
			Prior to conducting Plant Performance Tests, Contractor shall coordinate and schedule the CEMS certification.  If the CEMS has not been certified, the Performance Tests can be conducted using a certified 3rd party stack tester.
		

		
			Contractor shall conduct tests to verify OTSG, CTG, and STG unit performance, plus combined cycle power output, fuel consumption, emissions, and Plant electric parasitic loads.  Contractor shall provide all necessary test instrumentation, parts and labor for the Performance Tests. Performance tests shall be performed in accordance with ASME PTCs as required, provisionally including aspects of PTC 4, 6, 22 and 46 and in accordance with Company-Procured Equipment suppliers’ testing requirements and conditions.
		

		
			During all Plant Performance Tests, the Plant shall be operated in a mode that is representative of the long-term normal operating configuration with all equipment operating as designed and within limits prescribed by manufacturers’ O&M manuals and the Operations and Maintenance Manuals consistent with Prudent Industry Practice.  No normally operating systems should be taken out of service, including bypassing or suppressing of alarms, unless specifically allowed for in the Company-approved test procedure.
		

		
			Instruments for primary measurements shall be calibrated using standard reference sources or shall have been previously calibrated and certified by independent nationally or internationally approved calibration authorities (NIST-traceable).
		

		
			Calibration certificates shall be provided for all test instruments at the time of test.  Any and all costs involved in preparation of calibration certificates shall be to Contractor’s account. 
		

		
			Precision test instrumentation will generally be utilized per the relevant ASME PTC.  Allowances will be made for measurement uncertainty in performance calculations. Measurement uncertainty will be based on the accuracy of the individual instruments used in conducting the Performance Tests.  An analysis of the pre-test measurement uncertainty shall be performed by Contractor, in accordance with ASME PTC 19.1 as part of the detailed Performance Test procedure and shall be submitted to Company for review and approval.  Post-test measurement uncertainty will be in the performance test report.
		

		
			For all equipment other than the CTGs the Performance Tests shall consist of four consecutive one-hour tests. During each one hour period all equipment shall meet the guarantees.
		

		
			4.2Plant BOP Load
		

		
			During the Plant net power output and Plant net heat rate tests the Plant total parasitic load power consumption shall be measured with the results corrected to Plant design

		conditions.  Test results shall be adjusted so that the corrected results do not include the parasitic load associated with Company-Procured Equipment, Company-Procured Equipment parasitic losses and electrical load associated with the Plant operations building. 
		

		
			4.3Air Emissions 
		

		
			Testing shall be done in accordance with the approved air permit, ADEC rules and regulations, EPA rules and regulations and in accordance with GE testing procedures and conditions.
		

		
			Normal Plant start-up and operating procedures shall be used when operating the units during the tests.  The CTGs shall be operated between minimum load of 50% based on Company Procured Equipment and 100% of baseload.
		

		
			4.4CTG Power Output, Heat Rate and Exhaust Energy
		

		
			Contractor shall conduct individual CTG power output, heat rate and exhaust energy tests to verify each CTGs performance while in compliance with the stack emissions guarantees listed in the table above. Each CTG shall be individually tested for generator gross electrical output and fuel input in accordance with the performance and acceptance testing requirements described in the GE CTG purchase agreement  appendices. The test data will be corrected to design conditions using the ASME Power Test Code 22 as modified by GE and by using GE’s correction curves and correction procedures. The Plant Performance Tests shall be completed as a condition of Substantial Completion. 
		

		
			Contractor shall provide instrumentation meeting the maximum allowable uncertainty criteria identified in the ASME PTC 22. Contractor shall prepare an uncertainty calculation in accordance with the procedures defined in ASME PTC 22 and by ASME PTC 19.1 to establish the overall test uncertainty.
		

		
			Contractor is only required to perform the CTG performance testing.  Contractor is not responsible for CTG equipment performance guarantees.
		

		
			During the Plant net power output and Plant net heat rate tests the GE supplied equipment parasitic load power consumption shall be measured with the results corrected to Plant design conditions.
		

		
			During the Plant net power output and Plant net heat rate tests, GSU losses shall be determined with the results corrected to Plant design conditions.
		

		
			4.5Noise Emissions
		

		
			Noise measurements shall be made with the Plant operating at baseload conditions in its normal Plant configuration.
		

		
			Noise tests shall only be carried out when weather conditions are dry with light winds.  Wind speed shall be calm and not exceed 5 mph during any noise measurements.  
		

		
			The results of the noise measurements shall be reported together with the operating conditions of the Plant equipment, meteorological conditions, noise measurement locations, and details of the instrumentation used for the measurements.  Any corrections made to the measured noise levels to take account of background noise levels or noise from other sources should be identified.
		

		
			Near-field Noise: Contractor shall guarantee that the sound level from all Equipment (other than Contractor Equipment) after erected and installed as an integrated part of the 
		

		 

		

			 

		

 

		

			EXECUTION VERSION

		

		

			CONTRACT NUMBER 51008 

		

		Plant shall not exceed 85 dBA when measured at five (5) feet above the base elevation of equipment and at a horizontal distance of three (3) feet from the Equipment surface.
		

		
			Equipment that need not meet the above criteria includes the following: gas compressors, air cooled condenser, building ventilators, stacks, CTG inlet, relief valve vents, and start-up valve vents.  
		

		
			The near-field noise level guarantee is limited to normal continuous operation of the Plant.  Each measurement of continuous Plant noise shall be made over 5 minute long sample periods.  Any extraneous noise shall be adjusted for.  The measuring equipment shall comply with ANSI S1.4 precision standards.  The test instrumentation shall be calibrated before use.  All noise tests shall be conducted by Contractor in accordance with ANSI Standards and good engineering practice.
		

		
			If the average of A-weighted sound levels, per piece of Equipment, assuming free-field measurement conditions, does not exceed 85 dBA, the Equipment will be considered to pass this portion of the noise guarantee.
		

		
			 
		

		
			4.6Reliability Test
		

		
			 
		

		
			The reliability test shall last for a period of 72 consecutive hours and shall demonstrate compliance with the Reliability Guarantee.
		

		
			The reliability test output shall be between 50% to 100% of full CTG power output based on a load schedule provided by Company and agreed by Contractor prior to commencing the run, and may include startups, shutdowns and other normal Equipment operation.
		

		
			The term "Equivalent Availability" is specifically defined as follows for the purposes of the reliability test:  EA = ((A+B+C)x100%)/72,
		

		
			 
		

		
			where:EA = Equivalent Availability in percent (%).
		

		
			A =Total number of hours during the reliability test that the Plant  is operating at the output required by dispatch control. These hours may include time to start-up, shut-down or other normal operation.
		

		
			B =Total number of hours during the test that the Plant is available for normal operation, but the Plant is not allowed to operate or not allowed to operate normally due to Company, Company-Procured Equipment defect or malfunction.
		

		
			C =Total number of hours during the test that the Plant is not operating, but is available for normal operation up to base load, including start-up, shutdown, coat-down or other normal unit operation.

			Instrumentation and control systems

		
			The exhaust gas from the CTG will be directed to the OTSG where energy is recovered to generate high and low-pressure steam.  Additional energy will be added by duct burners.
		

		
			High pressure superheated steam from each OTSG is routed to the steam turbine generator. 
		

		
			Low pressure steam from each OTSG will be routed to the steam turbine generator.
		

		
			Exhaust steam from the steam turbine generator will be condensed in an air cooled condenser.
		

		
			Cooling water for Plant auxiliary cooling will be supplied by a multi-cell air cooled heat exchanger.
		

		
			Power produced by the generator will pass through a generator step-up transformer (GSU) to an underground transmission line for delivery to a switchyard by others.
		

		
			Hot flue gas leaving the steam generator will be exhausted to atmosphere.  NOx emissions will be controlled by selective catalytic reduction (SCR) equipment; CO emissions will be controlled using catalytic oxidation equipment.
		

		
			The power plant will be controlled by a system of local control panels, local instrumentation and a central distributed control system.
		

			
	
			
				 24.1.1
			

			
	
			
			General Operating Philosophy

		
			The Plant design life will be 30 years.  The economic design life is also 30 years.  The Plant is expected to be used for base load power production to Company’s own grid system.  The Plant is not a merchant plant and will be dispatched by Chugach.
		

		
			The Plant will be designed for daily cycling but is expected to run base loaded in its initial years of operation.

			2.Unconditional Obligation.  This is a guarantee of payment and performance and not of collection.  The liability of Guarantor under this Guaranty is direct, irrevocable and not conditional or contingent upon the pursuit by Beneficiary under the Contract of any remedies against Contractor or any other Person, nor upon any other recourse available to Beneficiary.  Guarantor irrevocably waives any and all rights it may now or in the future have under law or in equity to require either (i) that an action be brought against Contractor or any other Person as a condition to Beneficiary proceeding against Guarantor, or (ii) that action be first taken against any security given by Contractor, Guarantor or any third party on behalf of or in favor of Contractor in connection with the Contract or to any balance of any deposit account or credit on the books of Beneficiary in favor of Contractor or any other person or entity before Beneficiary proceeds against Guarantor under this Guaranty.  
		

		
			 
		

		
			3.Absolute Obligation.  Subject only to the provisions of Section 4, the obligations of Guarantor under this Guaranty are absolute and without regard to the enforceability of the Contract or of any terms thereof, or lack of power or authority of Contractor to enter into the Contract, or any substitution, taking, release or exchange of any other guaranty of or any security for Contractor’s performance under the Contract or any other circumstances which might otherwise constitute a legal or equitable discharge of a surety or guarantor.  Without limitation, the obligations of Guarantor under this Guaranty shall not be affected, reduced, modified, impaired or discharged upon the occurrence of any of the following events:
		

		
			 
		

		
			(a)the change, modification or amendment of any obligation, duty, guarantee, warranty, responsibility, covenant or contract (including without limitation Change Orders (as such term is defined in the Contract)) set forth in the Contract;
		

		
			 
		

		
			(b)any failure, omission, delay by or inability on the part of Beneficiary to assert or exercise any right, power or remedy conferred upon Beneficiary under the Contract or this Guaranty;
		

		
			 
		

		
			(c)the voluntary or involuntary liquidation, dissolution, sale or other disposition of all or substantially all of any of Contractor’s assets, the receivership, insolvency, bankruptcy, assignment for the benefit of creditors, reorganization of, or similar proceedings affecting Contractor or any of the assets of Contractor;

			(g)any ongoing dispute, causes of action, mediation, arbitration or other proceedings between Beneficiary and Contractor under or in connection with the Contract or any other contract to which Beneficiary and Contractor are parties.
		

		
			 
		

		
			4.Limitation on Liability.  Notwithstanding anything to the contrary contained in this Guaranty, Guarantor’s obligations under this Guaranty shall in no event be greater than the obligations of the Contractor under the Contract.  The Guarantor’s obligations hereunder shall be subject to the same limitations as limit Contractor’s duties, obligations and liabilities under the Contract, and Guarantor shall be entitled to assert the same limitations of liability (including but not limited to monetary and time), and exclusions of types of damages, against Beneficiary hereunder as Contractor might assert against Beneficiary under the Contract, and shall be further entitled to assert hereunder all of the rights and defenses that Contractor has under the Contract.  
		

		
			 
		

		
			5.Waiver of Notice.  Guarantor hereby waives notice of (i) Beneficiary’s acceptance and reliance on this Guaranty; (ii) default or demand in the case of default, provided such notice or demand has been given to Contractor in accordance with the terms of the Contract; and (iii) any indulgences, extensions or consents granted to Contractor or any other surety.  Guarantor waives promptness, diligence, presentment, demand of payment or enforcement and any other notice with respect to any of the Guaranteed Obligations and this Guaranty.  Without limiting Guarantor’s waiver in the preceding sentence, Beneficiary may, in its sole discretion, elect to furnish a duplicate notice to Guarantor of any notice provided to Contractor in connection with a claim which may result in Guarantor’s liability for any Guaranteed Obligations. 
		

		
			 
		

		
			6.Subrogation Rights.  Until the expiration of this Guaranty, any subrogation rights of Guarantor arising by reason of any payments made under this Guaranty shall be subordinate to the performance and payment in full by Contractor of all obligations under the Contract, including, without limitation, payment in full of all amounts which may be owing by Contractor to Beneficiary thereunder.
