Should said facilities be delayed beyond said date due to any of the aforesaid causes, it shall nevertheless be completed as soon thereafter as practicable. 1.07 The parties shall cooperate to assure the maximum practicable coordination of design and installation of the facilities to be installed by each of them with new and existing facilities of the other. Each party agrees to promptly notify the other party of any potential delay in the In-Service Date. Synchronous Operation 1.08 When the installation of the facilities as provided for under this Article 1 is completed, the systems of the parties shall be connected at the Interconnection Point and thereafter throughout the duration of this agreement, subject to the provisions of this Section 1.08 and Section 1.09, such systems shall be operated in continuous synchronism through such line. If synchronous operation of the systems through such line becomes interrupted either manually or automatically because of reasons beyond the control of either party or because of scheduled maintenance that has been agreed to by both parties, the parties shall cooperate to remove the cause of such interruption as soon as practicable and restore such line to normal operating condition. Neither party shall be responsible to the other party for any damage or loss of revenue caused by any such interruption. 1.09 The parties hereto agree that either party may interrupt synchronous operation through this interconnection if either determines that its facilities may be damaged due to excessive loadings, and such loadings may be reduced or alleviated by such interruption. If such interruption occurs, the parties shall cooperate to remove the cause of such loadings as soon as practicable and restore such interconnection to normal operating condition. Neither party shall be responsible to the other party for damage or loss of revenue caused by such interruption. The parties hereto further agree to study and negotiate the installation, ownership, and cost of any additional equipment necessary to effect a long term solution to any such excessive loading herein described in the event either party determines that this interconnection contributes to the excess loading and requests such negotiation. Maintenance of Equipment 1.10 The parties hereto shall each keep the lines, together with all associated equipment and appurtenances, described in Article 1 hereof that are located on their respective sides of the Interconnection Point in a suitable condition of repair at all times, each at its own expense, in order that said lines will operate in a reliable and satisfactory manner and in order that reduction in the capacity of said lines will be avoided to the extent practicable. 1.11 The parties hereto understand that IPL and Hoosier each now has its transmission system interconnected with the electric transmission systems of other electric utility companies and each has contracted for other such interconnections and may hereafter during the term of this agreement desire to make additional interconnections with such companies or with other electric utility companies. Each such additional interconnection with another electric utility system shall be discussed between the parties and if, in the opinion of either party, the establishment of such interconnection will cause transfer of power or reactive power through the system of either party during normal parallel operation to or from the systems with which either party proposes to add an interconnection to its system, then before any such additional interconnection is made, joint load studies shall be carried on to determine the effect which such interconnection will have on the transmission systems of the parties. If as the results of such studies it is the reasonable opinion of one of the parties that the proposed additional interconnection would cause unreasonable transfers of power or reactive power through the electric transmission system of such party or otherwise impair the ability of such party to carry out its own obligations, then the party proposing such additional interconnection shall, before such proposed interconnection is placed in service: 1.111 agree to compensate the other party for the use of that portion of its facilities determined to be dedicated to the new situation caused by the establishment of the proposed interconnection; and/or 1.112 install and/or remove such equipment as may be reasonably necessary to avoid such unreasonable transfers of power or reactive power; or 1.113 abandon the establishment of such additional interconnection. ARTICLE 2 SERVICES TO BE RENDERED 2.01 It is the purpose of the parties hereto to realize on an equitable basis, all benefits practicable to be effected through coordination in the operation and development of their respective systems. It is understood by the parties that such benefits may be realized under the stated terms and conditions of the following interconnection services: A. the furnishing of mutual emergency and standby assistance, in accordance with Service Schedule A annexed hereto; B. the transfer of electric energy through the transmission system of one party for the benefit of the other, in accordance with Service Schedule B annexed hereto; C. the interchange, sale, and purchase of energy to effect operating economies, in accordance with Service Schedule C annexed hereto; D. the sale and purchase of short-term electric power and energy available on the system of one party and needed on the system of the other, in accordance with Service Schedule D annexed hereto; E. the sale and purchase of limited term power and energy available on the system of one party and needed on the system of the other, in accordance with Service Schedule E annexed hereto; F. the sale and purchase of diversity power and energy, in accordance with Service Schedule F annexed hereto. In furtherance of such purpose the parties hereto shall create an Operating Committee as provided in Article 7 hereof. 2.02 Inasmuch as the specific services to be rendered in furtherance of such purpose will vary, and the terms and conditions applicable to such services may require modification from time to time while this Agreement is in effect, it is intended that such specific services and the terms and conditions applicable thereto be set forth in service schedules mutually agreed upon from time to time between the parties. Such service schedules, until and unless changed by such mutual agreement, shall be those provided by Section 2.03 hereof, each of which, while in effect, shall be deemed to be a part of this agreement. Nothing contained herein shall be construed as affecting in any way the right of IPL in furnishing service under these rate schedules to unilaterally make application to the Federal Energy Regulatory Commission ("FERC") for a change in rates under Section 205 of the Federal Power Act and pursuant to the FERC's Rules and Regulations promulgated thereunder. Nothing contained herein shall be construed as affecting in any way the right of Hoosier in furnishing service under these rate schedules to unilaterally make application to the Public Service Commission of Indiana for a change in rates in accordance with the Public Service Commission Act and pursuant to such Commission's Rules and Regulations promulgated thereunder. 2.03 The respective service schedules shall be designated: I. Service Schedule A - Emergency Service II. Service Schedule B - Energy Transfer III. Service Schedule C - Interchange Power IV. Service Schedule D - Short Term Power V.

ARTICLE 3 SERVICE CONDITIONS Control of System Disturbance 3.01 The parties hereto shall maintain and operate their respective systems in accordance with sound operating practice so as to minimize the likelihood of disturbance originating in either system which might cause impairment to the service of the system of the other party or of any system interconnected with the system of the other party. Control of Kilovar Exchange 3.02 It is intended that neither party hereto shall be obligated to deliver kilovars for the benefit of the other party; also that neither party shall be obligated to receive kilovars when to do so may introduce objectionable operating conditions on its system. The Operating Committee shall be responsible for the establishment from time to time of operating procedures and schedules, in respect of carrying kilovar loads by one system for the other in order to secure adequate service and economical use of the facilities of both systems and in respect of proper charges, if any, for the use of facilities carrying kilovar loads. In discharging such duties the Operating Committee shall recognize that in the transmission and delivery of power and energy hereunder the carrying of kilovar loads by either of the parties, in harmony with sound engineering principles of transmission operation with their systems interconnected, is subject to numerous variables contingent upon loading and operating conditions existing simultaneously on both of their systems. The operating procedures and schedules so set up by the Operating Committee shall be in accord with such principles and shall require each of the parties to carry kilovar loads at such times and in such amounts as will be equitable to both parties. Control of Unscheduled Power Deliveries 3.03 The parties hereto shall exercise reasonable foresight in carrying out all matters related to the providing and operating of their respective electric power resources so as to minimize to the extent practicable deviations between actual and scheduled deliveries of electric power and energy between their systems. The parties shall provide and install on their respective systems such communication and telemetering facilities as are essential to so minimize such deviations; and, in developing and executing operating procedures that will enable the parties to avoid, to the extent practicable, deviations from scheduled deliveries, shall fully cooperate with each other and with third parties whose systems are either directly or indirectly interconnected with the systems of the parties and who of necessity, together with the parties, must unify their efforts cooperatively to achieve effective and efficient interconnected operation. The parties recognize, however, that, despite their best efforts to prevent the same, unscheduled deliveries of electric energy from one party to the other may occur. In such events, electric energy delivered hereunder shall be settled for either by the return of equivalent energy or by payment of the out-of-pocket cost (such cost being at the delivery point or points, set forth in Section 4.01 of this agreement, taking into account electrical losses incurred from the source or sources of such energy to said delivery point or points) of electric energy delivered hereunder to the supplying party plus ten percent of such cost. If equivalent energy is returned, it shall be returned at times when the load conditions of the party receiving it are substantially equivalent to the load conditions of such party at the time the energy for which it is returned was delivered or, if such party elects to have equivalent energy returned under different conditions, it shall be returned in such amounts, to be agreed upon by the Operating Committee, as will compensate for the difference in conditions. ARTICLE 4 DELIVERY POINTS, METERING POINTS, AND METERING Delivery Points 4.01 All electric energy delivered under this agreement shall be of the character commonly known as three-phase sixty-cycle energy, and shall be delivered at the Interconnection Point, as defined under Section 1.05 hereof, at a nominal voltage of 138,000-volts and at such other points and voltages as may be agreed upon by the parties in a written amendment hereto.

SECTION 2 - SERVICES TO BE RENDERED 2.1 Subject to the provisions of subsection 2.2 of this Section 2, in the event of a breakdown or other emergency in or on the system of either party involving either sources of power or transmission facilities, or both, impairing or jeopardizing the ability of the party suffering the emergency to meet the loads of its system, the other party shall supply to the party having the emergency such electric energy as the supplying party is requested to deliver; provided, that neither party shall be obligated to supply such emergency energy which, in the supplying party's sole judgment, cannot be delivered without creating a hazard to or economic burden upon its operations or without impairing or jeopardizing the total load requirements of its system; and provided further, that neither party shall be obligated to supply such emergency energy for a period in excess of forty-eight consecutive hours during any single emergency. 2.2 The parties recognize that the supply of electric energy as provided for in subsection 2.1 of this Section 2 is subject to two conditions which may preclude the delivery of such energy as so provided: (a) the party requested to deliver electric energy may be suffering an emergency in or on its own system as described in said subsection 2.1, or (b) the system of the party of whom such request is made may be delivering electric energy, under a mutual emergency interchange agreement, to the system of another interconnected company which is suffering an emergency in or on its system. Under conditions as cited under (a) above, neither party shall be considered to be in default hereunder if unable to comply with the provisions of said subsection 2.1. Under conditions as cited under (b) above, neither party shall be considered to be in default hereunder if it is unable to comply with the provisions of said subsection 2.1 provided that the aforesaid interconnected company has suffered said emergency in or on its system prior to and within forty-eight hours of that of the other party hereto and that, if requested by said other party, such delivery of electric energy to said interconnected company shall be discontinued within forty-eight hours following the start of such delivery, and a subsequent delivery shall be made for a full forty-eight hour period to said other party in accordance with the provisions of said subsection 2.1. 2.3 If at any time the record over a reasonably prior period shows clearly that either of the parties has failed to deliver energy in accordance with and subject to the provisions of subsection 2.1 and subsection 2.2 of this Section 2, either party, by written notice given to the other party, may call for a joint study by the parties of the reserve generating capacity in and provided for their respective systems and of their respective system transmission facilities affecting the supply and delivery of power and energy under the Agreement. It shall be the purpose of such study to determine the adequacy or inadequacy of reserve generating capacity and transmission facilities being provided to meet the requirements of the parties' respective systems, reflecting obligations under the Agreement, and, if inadequate, the extent of the burden that one party may be placing upon the other. If it should be found that one party is placing an unreasonable burden upon the other, the party causing such burden shall take such measures as are necessary to remove the burden from the other party, or the parties shall enter into such arrangements as shall provide for equitable compensation to the party being burdened. SECTION 3 - COMPENSATION 3.1 Emergency Energy shall be settled for, at the option of the supplying party, either by payment or by return of equivalent energy. 3.2 If the supplying party opts to receive payment for Emergency Energy delivered, the receiving party shall pay the supplying party the greater of: 3.21 110% of the out-of-pocket cost of supplying such Emergency Energy that is generated from the supplying party's own system, and, for energy purchased by the supplying party from another system to supply any part of such Emergency Energy, 100% of the amount paid by the supplying party therefor plus 10% of that amount, not exceeding, however, 1.6 mills per kilowatthour; or 3.22 30 mills per kilowatthour of such Emergency Energy 3.3 If the supplying party opts to receive equivalent energy for Emergency Energy delivered, such equivalent energy shall be returned at times when the load conditions of the party originally supplying Emergency Energy are substantially equivalent to the load conditions of such party that existed when the Emergency Energy was delivered or, if such party elects to have equivalent energy returned under different conditions, it shall be returned in such amounts and at such times as, the Operating Committee agrees will compensate the original supplying party, for the difference in conditions. EXHIBIT II SERVICE SCHEDULE B ENERGY TRANSFER SECTION 1 - DURATION 1.1 This Service Schedule, being a part of an agreement dated as of December 1, 1981, between Indianapolis Power & Light Company ("IPL") and Hoosier Energy Rural Electric Cooperative, Inc. ("Hoosier") (the "Agreement") shall become effective on the Interconnection Date as defined in Article 9 of the Agreement and shall continue in effect until termination of the Agreement. SECTION 2 - TRANSFER ARRANGEMENT 2.1 In carrying out the interconnected operation of their respective systems as provided for under the Agreement, energy being received by a portion of one party's system from another portion of its system or to the system of another interconnected company, may flow over the transmission facilities of the other party as a natural result of the physical and electrical characteristics of the interconnected network of transmission lines to which the parties are connected. Such flow of energy may occur during periods when conditions of system operation are normal or may occur during periods of emergency caused by the failure of either sources of power or transmission facilities, or both. In respect to such flow of energy (hereinafter called "energy transfer") the parties agree as follows: 2.11 Such energy transfer over their respective transmission facilities shall be permitted whenever such transfer occurs; provided, that such energy transfer shall not be of such magnitude or duration as to affect adversely, or jeopardize the ability of, the party over whose system such energy transfers occur to render or accept service to or from companies with which it now has, or at any time hereafter may have contractual arrangements for the interchange of power or energy. 2.12 The parties recognize that in carrying out the provisions of this Service Schedule, the above described energy transfer, either during periods when conditions of system operation are normal or during periods of emergency, or both, may eventually require the installation of additional transmission facilities in order that such energy transfer may be properly controlled to the end that the ability of the party over whose system such energy transfers occur to meet its own requirements, as described under 2.11 above, is not affected adversely or jeopardized. In the event the need for such additional transmission facilities becomes apparent to either of the parties during any term of this Service Schedule, upon written notice given by either party to the other party and as soon as practicable following such notice, the parties shall jointly reexamine conditions relating to energy transfer. In such reexamination, if called for, the parties shall agree upon such additional transmission facilities as may be required to be installed, if any, and upon an equitable basis for bearing the cost of installing, maintaining and operating such facilities, if installed. SECTION 3 - POWER AND ENERGY ACCOUNTING 3.1 The parties recognize that energy transfers as described under Section 2 of this Service Schedule, except for such amounts of electrical losses as may be incurred because of such energy transfers, are the simultaneous acceptance and delivery of like amounts of power and energy by and from the system of the party over whose system such energy transfers occur. Power and energy associated with energy transfers, including electrical losses associated therewith, shall be accounted for each clock-hour as provided for under Article 5 of the Agreement. Proper consideration to such electrical losses will be in accordance with the manner agreed upon by the Operating Committee. It is understood by the parties, however, that such electrical losses resulting from energy transfers, to be taken as losses over and above the losses prevailing under basic conditions agreed upon by the parties, shall be supplied simultaneously by the party for whom such energy transfers are being made. The parties agree that initially such basic conditions will be established as those that exist when the scheduled net delivery between the systems of the parties, and between their respective systems and the systems of other interconnected companies, is zero kilowatts. It is further understood that, from time to time, conditions may require the establishment of different basic conditions for such purpose. Either party by written notice given to the other party may call for a prompt reexamination and reconsideration of matters pertinent to the establishment of said basic conditions, whenever such reexamination appears to be warranted, and the parties will thereupon agree to effect such changes in the basic conditions, if any, that will equitably compensate the parties for such losses. Should such reexamination be required, a statement will be prepared by the parties which shall include in detail the amounts of energy delivered and received by the parties that are associated with energy transfer and the amounts of electrical losses associated therewith. EXHIBIT III SERVICE SCHEDULE C INTERCHANGE POWER SECTION 1 - DURATION 1.1 This Service Schedule, being a part of an agreement dated as of December 1, 1981, between Indianapolis Power & Light Company ("IPL") and Hoosier Energy Rural Electric Cooperative, Inc. ("Hoosier") (the "Agreement") shall become effective on the Interconnection Date as defined in Article 9 of the Agreement and shall continue in effect until termination of the Agreement. SECTION 2 - SERVICES TO BE RENDERED Economy Energy 2.1 Either party may arrange to purchase from the other party electric energy ("Economy Energy") when it is possible to effect a saving thereby and, when, in the sole judgment of the supplying party, such energy is available. Prior to each Economy Energy transaction, the amount of energy, the time of its delivery, and the charge therefore shall be determined by the parties. Receipt or delivery of Economy Energy may also be arranged with other interconnected systems not parties to this Agreement. Non-Displacement Energy 2.2 It is recognized that occasions will arise when transactions under subsection 2.1 above will be impracticable although a party may have electric energy (herein called "Non-Displacement Energy") which it is willing to make available from surplus capacity from its own system or from outside sources, or both and which can be utilized advantageously for short intervals by the other party. In such event, the party desiring such receipt of energy shall notify the other party of the extent to which it desires to obtain Non-Displacement Energy, and if the other party, in its sole judgment, determines that Non-Displacement Energy is available, schedules providing the periods and extent of use shall be mutually agreed upon. Neither party shall be obligated to make any Non-Displacement Energy available to the other. SECTION 3 - COMPENSATION Economy Energy 3.1 The charge for Economy Energy purchased by either party from the other shall be based on the principle that the purchasing party shall pay the out-of-pocket cost of the supplying party such energy and that the resulting savings to the purchasing party shall be equally shared by both parties. 3.2 When Economy Energy is obtained from or delivered to other interconnected systems not signatories to this Agreement, payments shall be based on the out-of-pocket cost of the supplying party or system providing the energy and an allocation of the gross savings to be realized. For such purpose, gross savings is defined as the difference between the out-of-pocket cost of the purchasing party or system to generate such energy, and the out-of-pocket cost of the supplying party or system to provide such energy. Such allocation shall be made as provided in subsections 3.21 and 3.22 of this section. 3.21 Each party or system participating in the transaction other than the supplying and purchasing parties or systems, shall be paid (a) its cost of purchasing the energy supplied, plus (b) its cost of any additional transmission losses incurred, plus (c) fifteen percent of the savings remaining after deducting all such costs for transmission losses. 3.22 The supplying party or system shall be paid out-of-pocket costs of providing the energy, plus one-half of the gross savings remaining after deducting all (b) and (c) costs enumerated in section 3.21 above. The receiving party or system shall be entitled to the other one-half of the such savings. Non-Displacement Energy 3.3 Non-Displacement Energy delivered hereunder shall be settled for either by return of equivalent energy or, at the option of the supplying party, by payment of the out-of-cost of the supplying party in generating or supplying such energy plus ten percent of such cost. Such cost shall be as of the delivery point or points, as provided for in Section 4.01 of said Interconnection Agreement, and shall take into account the electrical losses incurred from the source or sources of such energy to said delivery point or points. If equivalent energy is returned, it shall be returned at times when the load conditions of the receiving party are equivalent to the load conditions of such party at the time the energy was delivered. If such party elects to have equivalent energy returned under different conditions, such energy shall be returned in such amounts as will compensate the supplying party for the difference in conditions as agreed by the Operating Committee. EXHIBIT IV SERVICE SCHEDULE D SHORT TERM POWER SECTION 1 - DURATION 1.1 This Service Schedule, being a part of an agreement dated as of December 1, 1981, between Indianapolis Power & Light Company ("IPL") and Hoosier Energy Rural Electric Cooperative, Inc.

SECTION 2 - SERVICES TO BE RENDERED 2.1 Either party, by giving the other party sufficient notice, may reserve for periods of one or more days or weeks, such electric power (herein called "Short Term Power") as the supplying party at that time may have and is willing to supply as Short Term Power. The party asked to supply Short Term Power shall be the sole judge as to the amounts and periods that it has electric power available that may be reserved by the other party as Short Term Power. As used herein, the term "week" shall mean any seven consecutive days. 2.2 The party desiring to reserve Short Term Power shall specify in a notice to the other party the number of kilowatts and the period for which it desires to reserve such power and the desired delivery schedule for such power. The supplying party shall promptly acknowledge receipt of such notice and, shall signify the extent of its ability and willingness to supply power in accordance with the provisions of such notice. Any such notice or acknowledgement thereof initially may be given orally; however if requested by either party, it shall be confirmed in writing and such confirmation shall be forwarded not later than the third day following the day such oral notice is given, excluding Saturdays, Sundays and holidays. 2.3 During the period the Short Term Power has been reserved as provided in Section 2.2 above, the supplying party shall deliver upon call electric energy (herein called "Short Term Energy") to the other party at the delivery point or points set forth in Section 4.01 of the Agreement in amounts not to exceed the number of kilowatts reserved. However, in the event conditions arise during such period which could not have been reasonably foreseen at the time Short Term Energy was reserved and such conditions would cause the delivery of said power to be burdensome to the supplying party, said party shall have the right to require the purchasing party to reduce for any portion of such period the amount of such energy being taken to the amount specified by the supplying party. The purchasing party shall promptly comply with such requirement of the supplying party. SECTION 3 - COMPENSATION 3.1 The purchasing party shall pay the supplying party; 3.11 For any week that Short Term Power is reserved, $1.05 per kilowatt reserved; less, for each day during any part of which the amount of such Short Term Power is reduced by the supplying party, $0.18 per kilowatt of the reduction (except that in no event shall the total of such deductions in any week exceed $1.05 per kilowatt). For each period less than one week that Short Term Power is reserved, $0.18 per kilowatt reserved per day; less, for any day during any part of which the amount of Short Term Power is reduced by the supplying party, $0.18 per kilowatt of the reduction; plus 3.12 110% of the out-of-pocket cost of supplying the Short Term Energy taken during such reservation periods that comes from the supplying party's own system; plus, for energy purchased by the supplying party from another system to supply any part of the Short Term Energy taken during such reservation periods, 100% of the amount paid therefore by the supplying party plus 10% thereof not to exceed 1.6 mills per kilowatthour. EXHIBIT V SERVICE SCHEDULE E LIMITED TERM POWER (FIRM) SECTION 1 - DURATION 1.1 This Service Schedule, being a part of an agreement dated as of December 1, 1981, between Indianapolis Power & Light Company ("IPL") and Hoosier Energy Rural Electric Cooperative, Inc.

INDIANAPOLIS POWER & LIGHT COMPANY By /s/ Robert W. Hill Robert W. Hill Chairman and President HOOSIER ENERGY RURAL ELECTRIC COOPERATIVE, INC. By /s/ J. Steven Smith for Virgil E. Peterson Executive Vice President and General Manager EXHIBIT I SERVICE SCHEDULE A EMERGENCY SERVICE SECTION 1 - DURATION 1.1 This Service Schedule, being a part of an agreement dated as of December 1, 1981, between Indianapolis Power & Light Company ("IPL") and Hoosier Energy Rural Electric Cooperative, Inc. ("Hoosier") (the "Agreement") shall become effective on the Interconnection Date as defined in Article 9 of the Agreement and shall continue in effect until termination of the Agreement. SECTION 2 - SERVICES TO BE RENDERED 2.1 Subject to the provisions of subsection 2.2 of this Section 2, in the event of a breakdown or other emergency in or on the system of either party involving either sources of power or transmission facilities, or both, impairing or jeopardizing the ability of the party suffering the emergency to meet the loads of its system, the other party shall supply to the party having the emergency such electric energy as the supplying party is requested to deliver; provided, that neither party shall be obligated to supply such emergency energy which, in the supplying party's sole judgment, cannot be delivered without creating a hazard to or economic burden upon its operations or without impairing or jeopardizing the total load requirements of its system; and provided further, that neither party shall be obligated to supply such emergency energy for a period in excess of forty-eight consecutive hours during any single emergency. 2.2 The parties recognize that the supply of electric energy as provided for in subsection 2.1 of this Section 2 is subject to two conditions which may preclude the delivery of such energy as so provided: (a) the party requested to deliver electric energy may be suffering an emergency in or on its own system as described in said subsection 2.1, or (b) the system of the party of whom such request is made may be delivering electric energy under a mutual emergency interchange agreement, to the system of another interconnected company which is suffering an emergency in or on its system. Under conditions as cited under (a) above, neither party shall be considered to be in default hereunder if unable to comply with the provisions of said subsection 2.1. Under conditions as cited under (b) above, neither party shall be considered to be in default hereunder if it is unable to comply with the provisions of said subsection 2.1 provided that the aforesaid interconnected company has suffered said emergency in or on its system prior to and within forty-eight hours of that of the other party hereto and that, if requested by said other party, such delivery of electric energy to said interconnected company shall be discontinued within forty-eight hours following the start of such delivery, and a subsequent delivery shall be made for a full forty-eight hour period to said other party in accordance with the provisions of said subsection 2.1. 2.3 If at any time the record over a reasonably prior period shows clearly that either of the parties has failed to deliver energy in accordance with and subject to the provisions of subsection 2.1 and subsection 2.2 of this Section 2, either party, by written notice given to the other party, may call for a joint study by the parties of the reserve generating capacity in and provided for their respective systems and of their respective system transmission facilities affecting the supply and delivery of power and energy under the Agreement. It shall be the purpose of such study to determine the adequacy or inadequacy of reserve generating capacity and transmission facilities being provided to meet the requirements of the parties' respective systems, reflecting obligations under the Agreement, and, if inadequate, the extent of the burden that one party may be placing upon the other. If it should be found that one party is placing an unreasonable burden upon the other, the party causing such burden shall take such measures as are necessary to remove the burden from the other party, or the parties shall enter into such arrangements as shall provide for equitable compensation to the party being burdened. SECTION 3 - COMPENSATION 3.1 Emergency Energy shall be settled for, at the option of the supplying party, either by payment or by return of equivalent energy. 3.2 If the supplying party opts to receive payment for Emergency Energy delivered, the receiving party shall pay the supplying party the greater of: 3.21 110% of the out-of-pocket cost of supplying such Emergency Energy that is generated from the supplying party's own system, and, for energy purchased by the supplying party from another interconnected system which is not a signatory to this Agreement ("Third Party") at the request of the receiving party, 100% of the amount paid to such Third Party plus up to 3.46 mills per kilowatthour (consisting of up to 2.46 mills per kilowatthour for a transmission charge and 1 mill per kilowatthour for difficult to quantify energy related costs) plus any transmission losses. 3.22 30 mills per kilowatthour of such Emergency Energy 3.3 If the supplying party opts to receive equivalent energy for Emergency Energy delivered; such equivalent energy shall be returned at times when the load conditions of the party originally supplying Emergency Energy are substantially equivalent to the load conditions of such party that existed when the Emergency Energy was delivered or, if such party elects to have equivalent energy returned under different conditions, it shall be returned in such amounts and at such times as, the Operating Committee agrees will compensate the original supplying party, for the difference in conditions. EXHIBIT II AMENDED SERVICE SCHEDULE B ENERGY TRANSFER SECTION 1 - DURATION 1.1 This Service Schedule, being a part of an agreement dated as of December 1, 1981, between Indianapolis Power & Light Company ("IPL") and Hoosier Energy Rural Electric Cooperative, Inc. ("Hoosier") (the "Agreement") shall become effective on the Interconnection Date as defined in Article 9 of the Agreement and shall continue in effect until termination of the Agreement. SECTION 2 - TRANSFER ARRANGEMENT 2.1 In carrying out the interconnected operation of their respective systems as provided for under the Agreement, energy being received by a portion of one party's system from another portion of its system or to the system of another interconnected company, may flow over the transmission facilities of the other party as a natural result of the physical and electrical characteristics of the interconnected network of transmission lines to which the parties are connected. Such flow of energy may occur during periods when conditions of system operation are normal or may occur during periods of emergency caused by the failure of either sources of power or transmission facilities, or both. In respect to such flow of energy (hereinafter called "energy transfer") the parties agree as follows: 2.11 Such energy transfer over their respective transmission facilities shall be permitted whenever such transfer occurs; provided, that such energy transfer shall not be of such magnitude or duration as to affect adversely, or jeopardize the ability of, the party over whose system such energy transfers occur to render or accept service to or from companies with which it now has, or at any time hereafter may have contractual arrangements for the interchange of power or energy. 2.12 The parties recognize that in carrying out the provisions of this Service Schedule, the above-described energy transfer, either during periods when conditions of system operation are normal or during periods of emergency, or both, may eventually require the installation of additional transmission facilities in order that such energy transfer may be properly controlled to the end that the ability of the party over whose system such energy transfers occur to meet its own requirements, as described under 2.11 above, is not affected adversely or jeopardized. In the event the need for such additional transmission facilities becomes apparent to either of the parties during any term of this Service Schedule, upon written notice given by either party to the other party and as soon as practicable following such notice, the parties shall jointly reexamine conditions relating to Energy Transfer. In such reexamination, if called for, the parties shall agree upon such additional transmission facilities as may be required to be installed, if any, and upon an equitable basis for bearing the cost of installing, maintaining and operating such facilities, if installed. SECTION 3 - POWER AND ENERGY ACCOUNTING 3.1 The parties recognize that energy transfers as described under Section 2 of this Service Schedule, except for such amounts of electrical losses as may be incurred because of such energy transfers, are the simultaneous acceptance and delivery of like amounts of power and energy by and from the system of the party over whose system such energy transfers occur. Power and energy associated with energy transfers, including electrical losses associated therewith, shall be accounted for each clock-hour as provided for under Article 5 of the Agreement. Proper consideration to such electrical losses will be in accordance with the manner agreed upon by the Operating Committee. It is understood by the parties, however, that such electrical losses resulting from energy transfers, to be taken as losses over and above the losses prevailing under basic conditions agreed upon by the parties, shall be supplied simultaneously by the party for whom such energy transfers are being made. The parties agree that initially such basic conditions will be established as those that exist when the scheduled net delivery between the systems of the parties, and between their respective systems and the systems of other interconnected companies, is zero kilowatts. It is further understood that, from time to time, conditions may require the establishment of different basic conditions for such purpose. Either party by written notice given to the other party may call for a prompt reexamination and reconsideration of matters pertinent to the establishment of said basic conditions, whenever such reexamination appears to be warranted, and the parties will thereupon agree to effect such changes in the basic conditions, if any, that will equitably compensate the parties for such losses. Should such reexamination be required, a statement will be prepared by the parties which shall include in detail the amounts of energy delivered and received by the parties that are associated with energy transfer and the amounts of electrical losses associated therewith. Accepted and approved this 8th day of December, 1989. HOOSIER ENERGY RURAL ELECTRIC INDIANAPOLIS POWER & LIGHT COMPANY COOPERATIVE, INC. By /s/ R.E. Jones /s/ J.C. Berlier R.E. Jones, Division Manager J.C. Berlier, Vice President Power Supply Supply Planning and Rates EXHIBIT III SERVICE SCHEDULE C INTERCHANGE POWER SECTION 1 - DURATION 1.1 This Service Schedule, being a part of an agreement dated as of December 1, 1981, between Indianapolis Power & Light Company ("IPL") and Hoosier Energy Rural Electric Cooperative, Inc. ("Hoosier") (the "Agreement") shall become effective on the Interconnection Date as defined in Article 9 of the Agreement and shall continue in effect until termination of the Agreement. SECTION 2 - SERVICES TO BE RENDERED Economy Energy 2.1 Either party may arrange to purchase from the other party electric energy ("Economy Energy") when it is possible to effect a saving thereby and, when in the sole judgment of the supplying party, such energy is available. Prior to each Economy Energy transaction, the amount of energy, the time of its delivery, and the charge therefore shall be determined by the parties. Receipt or delivery of Economy Energy may also be arranged with other interconnected systems not parties to this Agreement. Non-Displacement Energy 2.2 It is recognized that occasions will arise when transactions under subsection 2.1 above will be impracticable although a party may have electric energy (herein called "Non-Displacement Energy") which it is willing to make available from surplus capacity from its own system or from outside sources, or both and which can be utilized advantageously for short intervals by the other party. In such event, the party desiring such receipt of energy shall notify the other party of the extent to which it desires to obtain Non-Displacement Energy, and if the other party, in its sole judgment, determines that Non-Displacement Energy is available, schedules providing the period and extent of use shall be mutually agreed upon. Neither party shall be obligated to make any Non-Displacement Energy available to the other. SECTION 3 - COMPENSATION Economy Energy 3.1 The charge for Economy Energy purchased by either party from the other shall be based on the principle that the purchasing party shall pay the out-of-pocket cost of the supplying party such energy and that the resulting savings to the purchasing party shall be equally shared by both parties. 3.2 When Economy Energy is obtained from or delivered to a system interconnected with either of the Parties which is not a signatory in the Agreement ("Third Party"), payments among the participants in such a transaction shall be based on the out-of-pocket costs of the supplying party or Third Party providing the Energy and an allocation of the gross savings, which are defined as the difference between (1) what the out-of- pocket costs of the receiving party or Third Party would have been to generate such Energy, and (2) the out-of-pocket costs of the supplying party or Third Party providing the Energy. Such allocation shall be made as provided in subsection 3.21 and 3.22 hereinbelow. 3.21 The transmitting party shall be paid (A) its cost of purchasing the Energy supplied, plus (B) its costs of any additional transmission losses incurred, plus (C) the greater of fifteen percent of the gross savings remaining after deducting all such payments for transmission losses or an amount up to 3.46 mills per kilowatthour of Energy received for transmission. 3.22 The supplying party or Third Party shall be paid its out- of-pocket costs of providing the Energy, plus one-half of the gross savings remaining after deducting all payments made under subsection 3.21. Non-Displacement Energy 3.3 Non-Displacement Energy delivered hereunder that is generated by the supplying party's system shall be settled for either by return of equivalent Energy or, at the option of the supplying party, by the payment of the out-of-pocket costs of the supplying party generating such Energy plus ten percent of such cost. If equivalent Energy is returned, it shall be returned at times when load conditions of the receiving party are equivalent to the load condition of such party at the time the energy was delivered or, different conditions, such energy shall be returned in such amounts, to be agreed upon by the operating committee, as will compensate for the difference in conditions. 3.4 Non-Displacement Energy delivered under subsection 2.2 above that is purchased by the supplying party from another interconnected system at the request of the receiving party shall be settled for by the payment of 100 percent of the amount paid to such Third Party, plus up to 3.46 mills per kilowatthour (consisting of up to 2.46 mills per kilowatthour for a transmission charge plus 1 mill per kilowatthour for difficult to quantify energy related costs) plus any transmission losses. EXHIBIT IV SERVICE SCHEDULE D SHORT TERM POWER SECTION 1 - DURATION 1.1 This Service Schedule, being a part of an agreement dated as of December 1, 1981, between Indianapolis Power & Light Company ("IPL") and Hoosier Energy Rural Electric Cooperative, Inc. ("Hoosier") (the "Agreement") shall become effective on the Interconnection Date as defined in Article 9 of the Agreement and shall continue in effect until termination of the Agreement. SECTION 2 - SERVICES TO BE RENDERED 2.1 Either party, by giving the other party sufficient notice, may reserve for periods of one or more days or weeks, such electric power (herein called "Short Term Power") as the supplying party at that time may have and is willing to supply as Short Term Power. The party asked to supply Short Term Power shall be the sole judge as to the amounts and periods that it has electric power available that may be reserved by the other party as Short Term Power. As used herein, the term "week" shall mean any seven consecutive days. 2.2 The party desiring to reserve Short Term Power shall specify in a notice to the other party the number of kilowatts and the period for which it desires to reserve such power and the desired delivery schedule for such power. The supplying party shall promptly acknowledge receipt of such notice and, shall signify the extent of its ability and willingness to supply power in accordance with the provisions of such notice.

MODIFICATION NO. 4 TO THE INTERCONNECTION AGREEMENT BETWEEN INDIANAPOLIS POWER & LIGHT COMPANY AND HOOSIER ENERGY RURAL ELECTRIC COOPERATIVE, INC. THIS AMENDMENT made and entered into as of the 1st day of January, 1995 by Indianapolis Power & Light Company ("IPL"), being an Amendment to the Interconnection Agreement between Hoosier Energy Rural Electric Cooperative, Inc. ("Buyer") and IPL dated December 1, 1981 (the "Agreement"). WITNESSETH: WHEREAS, IPL and Hoosier Energy Rural Electric Cooperative, Inc., entered into the Agreement on December 1, 1981, which Agreement has been amended from time to time; WHEREAS, the Agreement provides for the sale of power and energy by IPL under Service Schedules described as: Service Schedule A Emergency Service Service Schedule C Interchange Power Service Schedule D Short Term Power Service Schedule E Limited Term Power (Firm) Service Schedule F Diversity Power WHEREAS, the Agreement provides for the recovery of incremental costs or "out-of-pocket" costs occasioned by the sale by IPL of electric energy; WHEREAS, IPL has implemented its Emissions Constrained Dispatch Plan, attached hereto; WHEREAS, the rates for Emergency Service, Interchange Power, Short Term Power, Limited Term Power (Firm), and Diversity Power, do not expressly include the cost of replacing sulfur dioxide ("SO2") emission allowances expended in order to provide such energy in compliance with Federal laws governing SO2 emission; WHEREAS, IPL desires to amend the Agreement to clarify recovery of out- of-pocket costs occasioned by the sale of said energy as including the recovery of the incremental cost of SO2 emission allowances; NOW, THEREFORE, in consideration of the premises and the terms and conditions set forth herein; IPL desires to amend the Agreement as follows: Section 1. Compensation for SO2 Emission Allowances. The Buyer shall compensate IPL for the consumption of Sulfur Dioxide Emissions Allowances ("SO2 Allowances") directly attributed to electric energy sales by IPL to Buyer under the Service Schedules. Such compensation shall, at Buyer's option, be made by either supplying IPL with the number of SO2 Allowances directly attributed to such energy sales, or by reimbursing IPL for the incremental cost of such number of SO2 Allowances, rounded to the nearest whole SO2 Allowance. If Buyer opts to reimburse IPL in cash for SO2 Allowances associated with Buyer's energy purchases for the month, the cash amount due at billing will be determined by multiplying the number of SO2 Allowances attributed to the sale by the incremental cost of the SO2 Allowances, as determined in Section 2.2, at the time of the sale. If Buyer opts to reimburse IPL in SO2 Allowances, Buyer will record or transfer to IPL's account, the number of SO2 Allowances calculated below, at the time cash settlement for the energy is due. In all cases, Buyer will transfer to IPL's account the number of SO2 Allowances due IPL for calendar year no later than January 15 of the following year. "Transfer to IPL's account" shall mean, for purposes of the Amendment, the transfer by the USEPA of the requisite number of SO2 Allowances to IPL's Allowance Tracking System account and the receipt by IPL of the Allowance Transfer Confirmation. Section 2. Determination of SO2 Emission Allowances Due IPL. Section 2.1. Number of SO2 Allowances The number of SO2 Allowances directly attributed to an energy sale made by IPL shall be determined for each hour, by determining the contribution from each of the unit(s) from which the energy sale is being made for that hour. For each unit, the emission rate in pounds of SO2 per million Btu will be determined each month, from fuel sulfur content, control equipment performance, and continuous emissions monitoring data. The emission rate and the unit heat rate will be used to determine the SO2 Allowances used per megawatt-hour ("MWH"). The energy from each unit attributable to the sale, and the SO2 Allowances per MWH for each unit, will be used to determine the number of SO2 Allowances attributable to the sale. Section 2.2 . Cost of SO2 Allowances The incremental SO2 Allowance cost used to determine economic dispatch of IPL's generating units in any month, will also be the basis used to determine compensation for IPL's energy sales. The incremental SO2 Allowances cost, in dollars per ton of SO2, shall be determined each month and will be based on the Cantor Fitzgerald offer price for SO2 Allowances, or if such is not available, the another nationally recognized SO2 Allowance trading market price or market price index, at the beginning of the month. The SO2 Allowance value may be changed at any time during the month to reflect the more current incremental cost, or market price, for SO2 Allowances. Buyer will be notified of the new SO2 Allowance value prior to dispatch of IPL energy to Buyer. Section 3. Effective Date. This Amendment to the Agreement shall be made effective as of January 1, 1995. IN WITNESS WHEREOF, IPL has caused the foregoing Amendment to be signed by its duly authorized officer, effective as of the date set forth above. INDIANAPOLIS POWER & LIGHT COMPANY By: /s/ John C. Berlier, Jr. John C. Berlier, Jr. Vice President Resource Planning and Rates EMISSIONS CONSTRAINED DISPATCH PLAN Effective January 1, 1995 Economic Dispatch is loading each generating unit so the lowest cost generation is called upon first to generate the power needed, thereby minimizing total electric energy generation cost. Emissions Constrained Dispatch is simply Economic Dispatch where the estimated value of the SO2 allowances being consumed by a unit is included as a part of the unit's cost of generation. A lower emitting unit will reflect a relatively lower emissions cost because it requires fewer sulfur dioxide (SO2) allowances. IPL's plan to implement Emissions Constrained Dispatch is to incorporate SO2 allowance values into the existing Energy Management System (load dispatching system), which economically dispatches IPL's generation. As the generation required (load) increases, the available unit with the lowest incremental cost is dispatched to meet the increase. As the generation demanded decreases, the unit with the highest incremental cost is dispatched to reduce its generation, thereby minimizing cost. Currently, the Energy Management System uses incremental heat rates, along with fuel and variable operation costs to determine the incremental cost of generation on each unit in service. Effective January 1, 1995, SO2 emissions related costs will be included in each unit's incremental cost prior to the incremental costs being compared to make the unit dispatch. The incremental SO2 value will be in units of dollars per million British Thermal Units ($/MMBTU) and computed by the following guidelines: IPL plans to use EPA (Environmental Protection Agency) certifiable data for SO2 emission rates in conjunction with the incremental value of emission allowances to form the emissions dispatch cost in units of $/MMBTU. Each generating unit affected by the Clean Air Act will have its own specific SO2 emissions data input into the Energy Management System at the beginning of each month. That data will remain for the month unless projected coal deliveries for the month have an SO2 value that will change the current dispatch. The Fuel Supply Organization will notify the System Operation Office of the projected coal delivery SO2 emission rate in #SO2/MMBTU, so that a correct So2 emission rate can be input into the Energy Management System. Optimization of unit loadings in the Energy Management System is constrained by equipment physical limitations such as maximum rate of load pickup or maximum load reduction rate on a unit as well as contrained by the maximum and minimum capability of the units. IPL's Treasury Organization will not less often than the 10th day of each month supply the IPL System Operation Office the incremental value of an emission allowance in units of dollars per ton of SO2 based upon the Cantor Fitzgerald asking price for allowances, or other nationally recognized allowance trading market price, for use in IPL's emission constrained dispatch on a forward going basis. Beginning January 1, 1995, the allowance price that will be used for purposes of IPL's emissions constrained dispatch will be the asking price for allowances obtained from Cantor Fitzgerald on December 30, 1994. The Treasury Organization will track the emission allowance market and if a significant change in allowance prices occurs within a given month, the Treasury Organization may provide an updated allowance price value to the IPL System Operation Office. The updated allowance price will be entered into the Energy Management System and the economic dispatch algorithm will be updated accordingly. The emissions cost will be added with the fuel and variable operating cost to produce a total dispatch cost. The total dispatch cost will be combined with the incremental unit heat rate data to produce the total incremental dispatch cost as calculated by the following formula: INCREMENTAL COST = (Fuel Cost + Emissions Value Divided By Variable Operating Cost) X Incremental Heat Rate The dimensions for each of the variables is as follows: Emissions Value, $/MMBTU; Fuel Cost, $/MMBTU; Variable Operating Cost $/MMBTU; Incremental Heat Rate, MMBTU/MWH; Allowance Value, $/Allowance; Incremental Cost, $/MWH The dispatch made using the total incremental cost, including SO2 emissions related costs, will constitute IPL's Emissions Constrained Dispatch.

IPL hereby reserves and agrees to make available to Hoosier, except as otherwise provided in Section 2.5 below, sufficient capacity in said transmission system to provide for such transmission service subject, however, to the capacity of such transmission system required to serve the actual load of IPL's customers now and in the future. 2.2 IPL agrees to provide temporary transmission services to Hoosier for the purpose of delivering up to 20 MW of power (demand) and energy from any of the interconnection points between IPL and Hoosier for each of the tap points described and referred to in the 1981 Agreement as the Honey Creek and Mullinix Tap Points ("Tap Points"). This temporary transmission service shall be available at all times during the term of this Service Schedule G except as stated in Section 2.5 of this Service Schedule. 2.3 Any power (demand) and energy delivered by IPL to the Tap Points shall be simultaneously supplied to IPL from Hoosier at any other interconnection point or points provided for in the 1981 Agreement. The power and energy shall be adjusted to compensate IPL for electrical losses incurred in the delivery of such power. Any difference in power and energy delivered to Hoosier through said Tap Points and that supplied by Hoosier to IPL shall be settled for in accordance with Section 3.03 of the 1981 Agreement. 2.4 The parties shall plan, maintain and operate their respective systems in accordance with sound engineering and operating practice, so as to minimize the likelihood of disturbance(s) originating in either party's system which might cause impairment of the transmission service provided hereunder. 2.5 The Parties shall plan for continuous unrestricted operation to the Tap Points at all times; provided, that either party may interrupt or restrict service for necessary maintenance, system emergency, or if either determines that its facilities may be damaged due to excessive loadings caused by the transmission service provided hereunder. Should such interruptions or restrictions occur, the parties shall cooperate to restore such service to normal as soon as practicable. Excessive loads are current flows exceeding the normal facility ratings with all facilities in service, or current flows exceeding emergency facility ratings under contingency conditions. Neither party shall be responsible to the other party for damage or loss of revenue caused by such restrictions or interruptions. Excessive loadings shall be verified by either metering records or mutually agreed upon load flows. Maintenance outages shall be coordinated between the parties whenever possible. 2.6 IPL shall periodically conduct studies of its future system, and if such studies indicate problems due to IPL's load growth which may arise in the future due to the transmission service provided hereunder, shall as soon as practicable, develop plans and estimates of cost for the installation of any additional equipment or facilities necessary to effect a long term solution to such problem so that transmission services hereunder may be reliably continued, and shall notify Hoosier of such studies and plans. IPL shall use its best efforts to provide Hoosier with a three year advance notice of any impending problems. Upon approval of long term remedial plans by Hoosier, IPL shall proceed to install required facilities, and upon completion thereof, Hoosier shall commence reimbursement to IPL of Hoosier's proportionate share of costs involved in designing and installing such facilities which shall be calculated as a function of variables such as: a) Share of existing facilities utilized by each party, and; b) Timing of required capacity with and without Hoosier's power transfers; and c) Useful life of new facilities, and; d) Remaining term of Service Schedule, and; e) Other consequential variables determined at the time when excessive loadings are observed or mutually projected. In the event Hoosier does not elect to participate in the remedial plans prescribed above Hoosier may elect to continue service on a restricted basis when necessary and on an unrestricted basis at all other times.
