		GUARANTY
	 

	 
		                This GUARANTY, dated as of July 1, 2007
		(this “Guaranty”), by
		FIRSTENERGY SOLUTIONS CORP., an Ohio corporation (the “Guarantor”), in favor of the
		Guaranteed Parties (as defined in Section 5).
	 

	 
		WITNESSETH:
	 

	 
		                WHEREAS,  the Guarantor wishes
		to induce the Guaranteed Parties to enter into that certain Participation
		Agreement dated as of June 26, 2007 (the “Participation Agreement”) by and among FirstEnergy
		Generation Corp., as Lessee, the Guarantor, Mansfield 2007 Trust A, as Lessor,
		U.S. Bank Trust National Association, as Trust Company, Hillbrook Corp., as
		Owner Participant, The Bank of New York Trust Company, N.A., as Indenture
		Trustee, and The Bank of New York Trust Company, N.A., as Pass Through Trustee,
		and consummate the transactions contemplated therein with FirstEnergy
		Generation Corp., an Ohio corporation and wholly-owned subsidiary of the
		Guarantor; and
	 

	 
		                WHEREAS,  the Guaranteed
		Parties are unwilling to enter into such Participation Agreement and consummate
		the transactions contemplated therein unless the Guarantor enters into this
		Guaranty;
	 

	 
		                NOW, THEREFORE,  in order to
		induce the Guaranteed Parties to enter into such Participation Agreement and
		consummate the transactions contemplated therein, the Guarantor hereby agrees
		as follows:
	 

	 
		SECTION 1.
		DEFINED TERMS
	 

	 
		                Capitalized
		terms used in this Guaranty, including the recitals, and not otherwise defined
		herein shall have the respective meanings set forth in Appendix A to the
		Participation Agreement. The Rules of Interpretation set forth in Appendix
		A to the Participation Agreement shall apply to the terms used in and the
		interpretation of this Guaranty.
	 

	 
		SECTION 2.
		GUARANTY
	 

	 
		Section
		2.1.          
		Guaranty.
		 Subject to the terms and conditions in this Guaranty, the Guarantor
		hereby unconditionally and irrevocably guarantees to the Guaranteed Parties the
		due, punctual and full payment (when and as the same become due and payable)
		(the “Payment Obligations”), and, as applicable, performance
		by the Lessee of all of the Lessee’s obligations (the “Performance
		Obligations” and, together with the Payment Obligations, individually
		and collectively as the context may require, the
		“Obligations”) under the Lessee Documents in the event that
		the Lessee fails to pay when due and payable (by acceleration or otherwise), or
		perform when required, pursuant to the Lessee Documents, in each case, without
		regard to whether such Obligation is direct or indirect, absolute or
		contingent, now or hereafter existing or owing, voluntary or involuntary,
		created or arising by contract, operation of law or otherwise or incurred or
		payable before or after commencement of any proceedings by or against the
		Lessee under any bankruptcy law. In the case of any failure by the Lessee to
		perform any Obligation when required pursuant to the Lessee Documents, the
		Guarantor agrees to cause such performance or observance to be done, and in the
		case of any failure by the Lessee to make a 
	 

	 
		 
	 

	 

	 
		

	 

	 
		payment as and when the same
		shall become due and payable (by acceleration or otherwise), the Guarantor
		agrees to make such payment as and when such payment is due and payable.

	 

	 
		Section
		2.2.           Guaranty
		Absolute. This
		Guaranty is an absolute, unlimited and continuing guaranty of performance and
		payment of the Obligations in accordance with the Lessee Documents. This
		Guaranty is in no way conditioned upon any attempt to collect from the Lessee
		or upon any other event or contingency, and shall be binding upon and
		enforceable against the Guarantor without regard to the validity or
		enforceability of any Lessee Document or of any term thereof. 
	 

	 
		Section
		2.3.           Guaranty Not
		Assignable. The
		Guarantor shall not assign this Guaranty or any of its obligations hereunder to
		any Person; provided that when the Notes have been paid in full and the lien of
		the Indenture has been discharged, the Guarantor may assign this Guaranty to
		another Person with the explicit written consent of the Owner Participant, such
		consent not to be unreasonably withheld.
	 

	 
		Section
		2.5.          
		Reinstatement.
		 The obligations of the Guarantor herein shall continue to be effective or
		shall be reinstated, as the case may be, if at any time, payment of any amount
		guaranteed hereunder, or any part thereof, is rescinded or must otherwise be
		restored or returned upon the insolvency, bankruptcy or reorganization of the
		Lessee or otherwise. 
	 

	 
		Section 2.6.
		          Guaranty Not
		Subject to Setoff, etc.  The obligations of the Guarantor
		hereunder shall not be subject to any counterclaim, setoff, deduction or
		defense (other than payment or performance) based upon any claim or defense the
		Lessee may have against any Guaranteed Party or any claim or defense the
		Guarantor may have against the Lessee or any other Person and shall remain in
		full force and effect (subject to Section 2.3) until payment in full (or
		other satisfaction), performance (or other satisfaction), or transfer of this
		Guaranty as provided in Section 3.2, of all of the Obligations, and such
		obligations shall not be released, discharged, reduced or in any way affected
		by, any circumstance or condition whatsoever which might constitute a legal or
		equitable discharge or defense including, but not limited to, (a) the
		modification or amendment (by operation of law or otherwise), expressly or
		impliedly, of any Lessee Document, or any other instrument applicable to the
		Lessee or to its Obligations, or any part thereof; (b) the default or failure
		on the part of the Lessee to perform or comply with any term of any Lessee
		Document; (c) any waiver, consent, extension, indulgence or other action or any
		action or inaction under or in respect of any Lessee Document, including this
		Guaranty; (d) any bankruptcy, insolvency, reorganization, arrangement,
		readjustment, composition, liquidation or similar proceeding with respect to
		the Guarantor or the Lessee, or their respective properties or their creditors,
		or any action taken by any trustee or receiver or by any court in any such
		proceeding; (e) any furnishing or acceptance of additional security or any
		release of any security (and the Guarantor authorizes each Guaranteed Party to
		furnish, accept or release said security); (f) any lack of validity or
		unenforceability, in whole or in part, of any Lessee Document, or any term
		thereof; (g) any change in the time, manner or place of payment of, or any
		other term of, all or any of the Obligations; (h) any merger or consolidation
		of the Lessee into or with any other Person or any direct or indirect sale,
		lease or transfer of any other assets of the Lessee to any other Person; (i)
		any change in the ownership of any shares of capital stock of the Lessee
		(including any such change which results in the Guarantor no longer owning
		capital stock of the Lessee); (j) any assumption of the Notes by the Lessee
		pursuant to the terms of any Lessee 
	 

	 
		2
	 

	 

	 
		

	 

	 
		Document or otherwise; or (k)
		any other event or circumstance whatsoever (other than payment and performance,
		or other satisfaction, in full of the Obligations, or transfer of this Guaranty
		as provided in Section 3.2).
	 

	 
		Section 2.7.          
		Subrogation.
		 The Guarantor will not exercise any rights which it may acquire by way of
		subrogation hereunder, by any payment made hereunder or otherwise, unless and
		until all of the Obligations have been paid in full, or performed, as the case
		may be, (or otherwise satisfied). If any amount shall be paid to the Guarantor
		on account of such subrogation rights at any time when all of the Obligations
		shall not have been paid in full, performed or otherwise satisfied, such amount
		shall be held in trust for the benefit of the Guaranteed Parties and shall
		forthwith be paid as provided in Section 6.1 on account of the
		Obligations, whether matured or unmatured, and thereafter to be applied in
		accordance with the terms of the Lessee Document under which such Obligation
		arose, when such Obligation is due and payable. If (a) the Guarantor shall make
		payment to any Guaranteed Party of all or any part of the Obligations and (b)
		all the Obligations shall be paid in full, performed, or otherwise satisfied,
		such Guaranteed Party will, at the Guarantor’s request and expense,
		execute and deliver to the Guarantor appropriate documents, without recourse
		and without representation or warranty, necessary to evidence the transfer by
		subrogation to the Guarantor of an interest in the Obligations resulting from
		such payment by the Guarantor.
	 

	 
		Section
		2.8.           Exercise of
		Rights.  Each
		Guaranteed Party may, at its election, exercise any right or remedy it might
		have against the Lessee or any security held by such Guaranteed Party,
		including the right to foreclose upon any such security by judicial or
		nonjudicial sale, without affecting or impairing in any way the liability of
		the Guarantor hereunder, except to the extent the Obligations are paid or
		satisfied from such exercise of rights, or otherwise, and the Guarantor waives
		any defense arising out of the absence, impairment or loss of any right of
		reimbursement, contribution or subrogation or any other right or remedy of the
		Guarantor against the Lessee or any such security, whether resulting from such
		election by such Guaranteed Party, or otherwise. 
	 

	 
		Section
		2.9.           Right to
		Deal with the Lessee.
		 At any time, and from time to time, without terminating, affecting or
		impairing the validity of this Guaranty or the obligations of the Guarantor
		hereunder, any Guaranteed Party may deal with the Lessee in the same manner and
		as fully and as if this Guaranty did not exist and shall be entitled, among
		other things, to grant the Lessee, without notice or demand and without
		affecting the Guarantor’s liability hereunder, such extension or
		extensions of time to perform, renew, compromise, accelerate or otherwise
		change the time for payment of or otherwise change the terms of payment or any
		part thereof contained in or arising under any Lessee Document, or to waive any
		Obligation of the Lessee to perform any act or acts as such Guaranteed Party
		may deem advisable.

		Section
		3.4.           Compliance with
		Laws.  The
		Guarantor shall comply with all Applicable Laws, including all Environmental

		SECTION 4.
		REPRESENTATIONS AND WARRANTIES
	 

	 
		                The Guarantor represents and warrants to
		the Guaranteed Parties that:
	 

	 
		Section
		4.1.
		          Organization;
		Power and Authority.
		 The Guarantor is a corporation duly organized, validly existing and in
		good standing under the laws of the State of Ohio. The Guarantor is duly
		qualified to do business in each other jurisdiction where the nature of its
		business requires such qualification other than any such jurisdiction where the
		failure to be so qualified would not result in a Material Adverse Effect. The
		Guarantor has all requisite power and authority to own its assets, conduct its
		business and execute, deliver and perform its obligations under this Agreement
		and the other Lessee Documents.
	 

	 
		Section
		4.2.          
		Authorization.
		 The execution, delivery and performance by the Guarantor of this Guaranty
		and each other Lessee Document to which it is a party have been duly authorized
		by all necessary corporate action on the part of the Guarantor, and, when
		executed and delivered, this Guaranty and each such other Lessee Document will
		constitute the legal, valid and binding obligation of the Guarantor enforceable
		against the Guarantor in accordance with its terms, except as such
		enforceability may be limited by (a) applicable bankruptcy, insolvency,
		fraudulent conveyance, reorganization, arrangement, moratorium or other
		Applicable Laws relating to or affecting the rights of creditors generally and
		(b) general principles of equity.
	 

	 
		Section
		4.3.          
		Non-Contravention.
		 The execution, delivery and performance of this Guaranty and each other
		Lessee Document to which it is a party do not and will not (a) contravene any
		Applicable Law binding on the Guarantor or its property, (b) require any
		action, consent or 
	 

	 
		5
	 

	 

	 
		

	 

	 
		approval by any trustee or
		holder of indebtedness of the Guarantor or other Person (other than those
		obtained prior to or on the Closing Date) or (c) constitute a violation of or a
		default under any indenture, mortgage or other material contract, instrument or
		agreement to which the Guarantor is a party or by which any of its property is
		bound, which in any case, individually or in the aggregate, is reasonably
		likely to result in a Material Adverse Effect.
	 

	 
		Section
		4.4.           Governmental
		Approvals.  All
		Permits which are required to be obtained (as of the date this representation
		is made or deemed to be made) in connection with the Guarantor’s execution
		and delivery of, or performance of its obligations under, this Guaranty and the
		other Lessee Documents to which it is a party have been obtained, were validly
		issued and are in full force and effect on the date hereof. No such Permit is
		the subject of any pending or threatened judicial or administrative proceeding,
		which judicial review or proceeding could have a Material Adverse Effect. The
		Guarantor is in compliance with all Permits required to be obtained by it as of
		the date this representation is made or deemed to be made. The Guarantor does
		not have any reason to believe that it will be unable to obtain the
		Governmental Approvals that are not required to be obtained prior to the date
		this representation is made or deemed to be made, which Governmental Approvals
		are set forth on Part II of Schedule 4.5, in the ordinary course
		of business and at such time or times as may be necessary to avoid any
		substantial delay in, or material impairment to, the performance of the
		transactions as contemplated by the Lessee Documents and the Operating
		Agreement.
	 

	 
		Section
		4.5.          
		Litigation.
		 There are no actions, suits, investigations or proceedings at law or in
		equity by or before any Governmental Entity pending against the Guarantor or,
		to its Actual Knowledge, threatened against the Guarantor, or any property or
		other assets or rights of the Guarantor or with respect to this Agreement or
		any other Lessee Document to which it is a party which (i) questions the
		validity of this Agreement or such Lessee Documents or the ability of the
		Guarantor to perform its obligations under this Agreement or such Lessee
		Documents or (ii) if determined adversely to it, could reasonably be expected
		to materially adversely affect the ability of the Guarantor to perform its
		obligations under this Agreement or such Lessee Documents.

		SUPPORT AGREEMENT, (this “Support Agreement”) dated as of

		WITNESSETH:
	 

	 
		                WHEREAS, Concurrently herewith,
		Lessee will sell, and Lessor will purchase, the Undivided Interest (such term
		and all other terms used herein without definition having the respective
		definitions to which reference is made in Article I below);
	 

	 
		                WHEREAS, Lessor and Lessee will
		enter into the Site Lease relating to the Facility Site;
	 

	 
		                WHEREAS, the Undivided Interest is
		subject to the terms and conditions of the Operating Agreement;
	 

	 
		                WHEREAS,  Lessee is a party to
		the Operating Agreement;
	 

	 
		                WHEREAS, Lessor wishes to acquire,
		and Lessee is willing to grant, certain rights with respect to the Operating
		Agreement;
	 

	 
		                WHEREAS, Lessor wishes to acquire,
		and Lessee is willing to grant, certain additional rights (referred to herein
		and in the other Operative Documents as the “Ancillary Rights”) to
		enable Lessor and its successors and assigns to realize the benefits of the
		Undivided Interest in a commercially reasonable manner from the end of the
		Facility Lease Term to the Site Lease Termination Date;
	 

	 
		                NOW, THEREFORE, in consideration of
		the premises and of other good and valuable consideration, receipt and
		sufficiency of which are hereby acknowledged, the parties hereto agree as
		follows:
	 

	 
		SECTION 1.
		          DEFINITIONS
	 

	 
		                Capitalized terms used in this Support
		Agreement, including the recitals, and not otherwise defined herein shall have
		the respective meanings set forth in Appendix A to the
		Participation Agreement, dated as of June 26, 2007 (the “Participation
		Agreement”), among the Lessee, FirstEnergy Solutions Corp., as
		Guarantor, the Lessor, U.S. Bank Trust National Association, as Trust Company,

		SECTION 2.
		          OPERATING
		AGREEMENT
	 

	 
		                Section 2.1.
		    Assignment to Lessor.  Lessee hereby assigns to
		Lessor, for a term commencing on the date hereof and expiring on the Site Lease
		Termination Date, all of its right, title and interest in, to and under the
		Operating Agreement, to the extent the same derive from or otherwise relate to
		Lessee’s ownership of the Undivided Interest, the Facility Site and the
		Ancillary Facilities.
	 

	 
		                Section 2.2.
		    Reassignment to Lessee.  Lessor hereby reassigns,
		subject to the Indenture for so long as the Notes are outstanding, to Lessee,
		for a term commencing on the date hereof and terminating upon the termination
		(for whatever reason) of the Facility Lease (the “Facility Lease
		Termination Date”) all right, title and interest of Lessor under the
		Operating Agreement assigned to Lessor pursuant to Section 2.1 hereof, but
		subject, however, to the terms and conditions of this Support Agreement.

	 

	 
		                Section 2.3.
		    Assumption by Lessor.  Except as provided in
		Section 2.4 hereof, Lessor agrees that, effective on the Facility
		Lease Termination Date and until the Site Lease Termination Date, Lessor shall
		assume and agree to fully perform and discharge all obligations of Lessee under
		the Operating Agreement in relation to the Undivided Interest, the Facility
		Site and the Ancillary Facilities, other than any such obligations
		(a) arising prior to the Facility Lease Termination Date or subsequent to
		the Site Lease Termination Date, (b) in respect of dismantling and the
		permanent removal from service of the Facility, which obligations shall be the
		obligations of Lessee or (c) in respect of Claims or Taxes for which the Lessor
		is indemnified under Section 9 of the Participation Agreement.
	 

	 
		                Section 2.4.
		    Release of Lessor.  In the event Lessor transfers
		all of its rights and obligations under the Operating Agreement to a
		“Transferee” (as that term is used in the Operating Agreement)
		pursuant to a valid assumption agreement (whether on the Facility Lease
		Termination Date or thereafter), Lessor shall therewith and thereupon be
		released and discharged from its obligations under Section 2.3
		hereof, if any, arising on or after the date of such assumption
		agreement.
	 

	 
		                Section 2.5.     No
		Release of Lessee.  Notwithstanding the provisions
		of Section 2.3 or 2.4 or any other provision hereof or of
		any other Operative Document, and except to the extent provided in this
		Section 2.5, Lessee shall not be released from any liability or
		obligation under the Operating Agreement, and Lessee shall remain liable for
		the payment and performance of its proportionate share of all such liabilities
		and obligations as such are derived from its Use of the Facility and the
		Facility Site prior to the Facility Lease Termination Date, including, but not
		limited to, any and all liabilities and obligations not assumed by Lessor, or a
		Transferee pursuant to Section 2.3 or 2.4 hereof. To the
		extent that the obligations of Lessee under the Operating Agreement have been
		assumed by Lessor, or a Transferee, Lessee shall be released from the
		obligations under the Operating Agreement so assumed and agreed to by Lessor or
		the Transferee.
	 

	 
		                Section 2.6.    
		Lessee to Act as Participant.  Lessee will, at all times
		during the Facility Lease Term, perform all obligations and discharge all
		liabilities for which it is responsible as a “Participant” (as
		that term is used in the Operating Agreement) in respect of the Undivided
		
	 

	 
		2
	 

	 

	 
	 

	 

	 
		Interest as set forth in the
		Operating Agreement, subject to the terms and conditions of this Support
		Agreement.
	 

	 
		                Section 2.7.
		    Rights as Participant.  Lessor shall, on the Facility
		Lease Termination Date (unless such date shall also be the Site Lease
		Termination Date), and any Person to which Lessor shall sell or lease the
		Undivided Interest shall, on the date of such sale or lease (provided that the
		provisions of Section 25(c) of the Operating Agreement have been
		complied with in connection with such sale or lease), be and become a
		Participant (with power to bind) for all purposes of the Operating Agreement,
		to the extent of the Undivided Interest (whether owned or leased), in all
		dealings with the other Participants in relation to the Undivided Interest and
		the rights assigned to Lessor pursuant to this Agreement. 
	 

	 
		                Section 2.8.
		    Interpretation of Operating
		Agreement.   Lessee and the other Participants
		signatory hereto acknowledge and agree with Lessor that none of the following
		actions may, under the terms of the Operating Agreement, be taken without the
		consent of and each Participant affected thereby:
	 

	 
		                (i)            amendment
		to or modification of the Operating Agreement;
	 

	 
		                (ii)           reduction
		of the “generation entitlement share” of any Participant; or
	 

	 
		                (iii)          increase
		in any Participant’s proportionate share of liabilities, obligations or
		costs.
	 

	 
		                Section
		2.9.     Right of First Offer.  (a) Lessee and each of the
		other Participants hereby acknowledge and agree that the provisions of
		Section 25(c) of the Operating Agreement shall not be applicable to (i)
		the conveyance on the Closing Date by Lessee to Lessor of the Undivided
		Interest, (ii) the lease by Lessor to Lessee of the Undivided Interest, (iii)
		the mortgage by Lessor to the Indenture Trustee of the Undivided Interest and
		the Ground Interest and the assignment of other rights in the Operative
		Documents and the Operating Agreement or the exercise of any rights and
		remedies under the Facility Lease, the Operating Agreement, the Indenture or
		any other Operative Document, (iv) any transfer by the Owner Participant of a
		beneficial interest in Lessor, (v) any subsequent purchase by Lessee of the
		Undivided Interest, or (vi) any sale, assignment or lease of the Undivided
		Interest and the Ground Interest to an Affiliate of Lessor, the Owner
		Participant or any successor or assign of either subsequent to the Facility
		Lease Termination Date.
	 

	 
		                (b)           Lessor
		hereby acknowledges and agrees that the provisions of Section 25(c) of
		the Operating Agreement shall be applicable to any sale or lease by it of the
		Undivided Interest, on or subsequent to the Facility Lease Termination Date, to
		any Person other than Lessee, an Affiliate of Lessor, the Owner Participant or
		any successor or assign of either.
	 

	 
		                (c)           Each
		of the parties hereto acknowledges and agrees that any offer made to the
		“Eligible Participants” for the sale or lease of the Undivided
		Interest pursuant to Section 25(c) of the Operating Agreement shall not
		be accepted for less than all of the interest so offered.

		                Section
		2.10.   No Obligation to Dismantle or
		Remove.  Without limiting the
		Lessee’s obligations under the other Operative Documents or the Operating
		Agreement, the Lessee shall not be obligated to dismantle or remove the

		                Section 2.11.  
		Termination of Assignment. On the Site Lease Termination Date,
		the assignment provided in Section 2.1 shall terminate; the rights
		and interests so assigned shall be vested in Lessee; and any obligations

		Lessee, all without further action by the parties hereto.
	 

	 
		                Section
		2.12.   Consent Decree.  For so long as (a) it is the
		Operator under the Operating Agreement, (b) it, or its Affiliate, controls the
		day-to-day operation and maintenance of the Generating Station or the Facility
		or (c) any obligations binding on the Lessee relating to
		both (i) the Generating Station or the Facility
		and (ii) any other generating facility operated or controlled by the
		Lessee, or its Affiliate, are still in force or effect under the Consent
		Decree, the Lessee shall comply with and perform all corrective or
		other actions under the Consent Decree and any other administrative or judicial
		orders or decrees by, with or of any Governmental Entity in a manner that is
		not materially adverse to the Generating Station, the Facility, the Facility
		Site, the Ancillary Facilities, or any portion or component thereof or interest
		therein (including the Undivided Interest).
	 

	 
		SECTION 3.
		          ACTIONS UNDER
		OPERATING AGREEMENT
	 

	 
		                Section 3.1.
		    Actions under Operating
		Agreement.   Lessee covenants and agrees with
		Lessor:
	 

	 
		                (a)           to
		maintain in full force and effect the Operating Agreement;
	 

	 
		                (b)           to
		cause the “Units” (as that term is defined in the Operating
		Agreement) and the Ancillary Facilities to be operated in accordance with the
		terms of the Operating Agreement; 
	 

	 
		                (c)           to
		perform all of its duties and obligations set forth in the Operating Agreement,
		and to exercise all of its rights thereunder to cause the Operator to perform
		its duties and obligations;
	 

	 
		                (d)           not
		to take any action or, except as otherwise required by the terms of the
		Operating Agreement, permit any action to be taken under the Operating
		Agreement (including without limitation any amendments or modifications
		thereof) without the prior written consent of Lessor, that would (i)
		discriminate, with respect to the Undivided Interest or the Ground Interest,
		between periods prior to the Facility Lease Termination Date and periods
		thereafter, (ii) result in significant liabilities accruing to Lessor or any
		successor or assign during periods after the Facility Lease Termination Date or
		(iii) adversely affect the rights of Lessor or any successor or assign under
		any Operative Document; and
	 

	 
		                (e)           without
		limiting the generality of the foregoing, not to consent to or permit any
		amendment to or modification of the Operating Agreement that would have the
		effect of (i) 
	 

	 
		4
	 

	 

	 
	 

	 

	 
		reducing the “generation
		entitlement share” of Lessee thereunder, (ii) increasing Lessee’s
		proportionate share of liabilities, obligations or expenses thereunder or (iii)
		changing the provisions of Section 25 of the Operating Agreement.

	 

	 
		                Section 3.2.    
		Consultation.  In furtherance of the
		agreements set forth in Section 3.1 and without limiting the generality
		thereof, Lessee hereby agrees that, to the extent any decision or determination
		to authorize additions, replacements or retirements in respect of any or all of
		the Generating Station which would result in material adverse changes in
		capability, useful life, basic methods of operation or similar matters is
		proposed to be made which would affect the operation of the Generating Station
		prior to such time as Lessor, the Owner Participant or either of their
		successors or assigns shall become a Participant under the Operating Agreement,
		Lessor (or any successor or assign thereof) shall be given prior notice of any
		meeting at which any such decision or determination is to be made or considered
		and an opportunity to discuss the same with Lessee. Lessee agrees to give good
		faith consideration of the recommendations of Lessor or such successor or
		assign, and to the extent it is possible under the Operating Agreement, to
		follow such recommendations.
	 

	 
		SECTION 4.
		          TRANSMISSION
		FACILITIES
	 

	 
		                Section 4.1.
		    Transmission Facilities.   Lessee shall make
		available to Lessor for transmission of its “generation entitlement
		share” from the Generating Station for the purpose of transmitting
		Lessor’s “generation entitlement share” to any public utility
		company or other entity, such transmission facilities which are owned by Lessee
		or to which it has access, and shall use its best efforts to obtain any consent
		or agreement of other parties required in connection therewith. Subject to any
		necessary Governmental Action and notice to and approval of MISO, the
		compensation payable by Lessor for the use of such other facilities shall, in
		the case of facilities owned by Lessee, be equal to the fair market value
		thereof and, in the case of facilities to which it has access, be equal to the
		charges that would then be payable by Lessee for such use.
	 

	 
		SECTION 5.
		          ANCILLARY
		FACILITIES 
	 

	 
		                Section 5.1.     Ancillary
		Facilities.    Lessee will during the period from the
		Facility Lease Termination Date or, if later, the date any repair or
		restoration of the Facility in accordance with Section 10 of the
		Facility Lease is completed and the Undivided Interest is returned in
		accordance with the provisions of Section 5 of the Facility Lease (the
		later of such dates, the “AF Start Date”) through the end of
		the Initial Term of the Site Lease, subject to any necessary Governmental
		Action and Applicable Law, lease to Lessor, to the full extent such would be
		available to Lessee (but only to such extent), a 16.8885% undivided
		leasehold interest in the Common Facilities and a 16.8885% undivided
		leasehold interest in the Shared Facilities pursuant to the Ancillary
		Facilities Lease in the form attached hereto as Exhibit B. The Lessor
		will have the right to renew the Ancillary Facilities Lease upon any renewal of
		the Site Lease Term for an equal and coterminous term.
	 

	 
		5
	 

	 

	 
	 

	 

	 
		                Section 5.2.
		    Compensation.  For the lease of the interest
		in the Ancillary Facilities provided pursuant to Section 5.1,
		Lessor will be required to pay to Lessee annual rent (a) for each year during
		the Initial Term of the Site Lease including and following the AF Start Date,
		equal to Lessor’s Percentage of the amount specified in Schedule 1
		hereto determined by reference to the AL Start Date and (b) for each year
		following the Initial Term of the Site Lease, an amount equal to Lessor’s
		Percentage of $2 million, in each case in semi-annual installments payable in
		arrears on each June 1 and December 1 during the term of the Site Lease,
		provided that any rent for a semi-annual period that does not begin or end on a
		payment date shall be prorated based on the number of days remaining divided by
		the total number of days in that period.
	 

	 
		                Section
		5.3.     Assets are Unique
		.
		 Lessee agrees that a breach of any of the
		covenants contained in Section 5.1
		 or Article VI
		 of the Ancillary Facilities Lease
		will cause irreparable injury to the Lessor; that Lessor has no adequate remedy
		at law in respect of such breach; and, as a consequence, that each and every
		covenant contained in Section 5.1
		 and Article VI
		 of the Ancillary Facilities Lease
		shall be specifically enforceable against Lessee. Lessee hereby waives and
		agrees not to assert any defenses against an action for specific performance of
		such covenants except for a defense that no breach has occurred or is
		continuing.
	 

	 
		SECTION 6.
		          OTHER RIGHTS
	 

	 
		                Section 6.1.
		    Access to Materials and Services Other than
		Ancillary Facilities.  Lessee covenants and agrees
		that, during the period from the Facility Lease Termination Date to the Site
		Lease Termination Date, it will make available to Lessor, access to materials
		and rights other than the Ancillary Facilities, that are necessary or
		commercially advisable for the use, repair, maintenance, modification, removal
		from service and dismantlement of the Facility and the Ancillary Facilities, to
		the extent the same derive from or otherwise relate to the Undivided Interest,
		including without limitation: (i) sufficient amounts of fuel and water for
		the operation and maintenance of the Undivided Interest, (ii) sufficient
		waste disposal facilities to dispose of all waste material from the Undivided
		Interest, including access to such facilities included in the Ancillary
		Facilities, and (iii) such other property, materials, supplies,
		intellectual property, ancillary rights and services as may be required from
		time to time to realize the benefits of the Undivided Interest in a
		commercially reasonable manner from the Facility Lease Termination Date to the
		Site Lease Termination Date, including, without limitation, rights and services
		related to transmission, limestone, sulfur dioxide treatment, coal storage, ash
		handling and access to docks, rail and all Generating Station areas.
	 

	 
		                Section 6.2.    
		Compensation.  Lessor shall pay to Lessee,
		for any materials and services provided pursuant to Section 6.1, the
		amounts that Lessee pays, or would pay, for such materials and services under
		contracts or arrangements then in effect or available to either of them.

	 

	 
		                Section
