Neither party shall be responsible to the other party for any damage or loss of revenue caused by any such interruption. ARTICLE 3 SERVICES TO BE RENDERED 3.01 It is the purpose in general of the parties to seek and realize 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 by them by carrying out under stated terms and conditions various interconnection services and transactions that may include among others: the sale and purchase of firm power and associated energy, the furnishing of mutual emergency and standby assistance, the interchange, sale, and purchase of energy to effect operating economies, the coordination of maintenance schedules of generating and transmission facilities, the transfer of electric energy through the transmission system of one party for the benefit of the other, and 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 furtherance of such purpose the parties shall appoint an Operating Committee as provided under Article 8. 3.02 Inasmuch as the specific services to be rendered in furtherance of such purpose will vary from time to time during the duration of this agreement, and the terms and conditions applicable to such services may require modification from time to time, it is intended that such specific services and the terms and conditions applicable thereto will be set forth in service schedules from time to time arranged between the parties. Such service schedules upon agreement of the parties, initially by Section 3.03 below or subsequently by separate execution, shall become parts of this agreement during the periods fixed by their respective duration. 3.03 The following service schedules are agreed to initially and hereby made a part of this agreement: Service Schedule A - Firm Power to Indianapolis Company Service Schedule B - Emergency Service Service Schedule C - Coordination of Scheduled Maintenance of Generating Facilities Service Schedule D - Energy Transfer Service Schedule E - Interchange Power Service Schedule F - Short Term Power ARTICLE 4 SERVICE CONDITIONS Control of System Disturbance 4.01 The parties shall maintain and operate their respective systems so as to minimize, in accordance with sound operating practice, 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 4.02 It is the intent that neither party 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 4.03 The parties shall exercise due diligence and 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 minimizing 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. Electric energy delivered hereunder in such event shall be settled for either by the return of equivalent energy or by payment of the out-of-pocket cost--such cost being as of the delivery point or points, as provided for in Section 5.01 of this agreement, taking into account electrical losses incurred from the source or sources of such energy to said delivery point or points--to the supplying party of generating or acquiring such energy plus ten per cent of such cost. If equivalent energy is returned, it shall be returned at times when the load conditions of the party receiving it are 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 5 DELIVERY POINTS, METERING POINTS, AND METERING Delivery Points 5.01 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 1.03 above, at a nominal voltage of 345,000 volts and at such other points and voltages as may be agreed upon by the parties. Metering Points 5.02 Electric power and energy supplied and delivered under this agreement shall be measured by suitable metering equipment provided, owned, and maintained by Indianapolis Company at the metering point at hereinbelow set forth; and at such other points, voltages, and ownership as may be agreed upon by the parties; viz.: 5.021 In respect of the Interconnection Point by 138,000-volt metering equipment installed at Hanna Substation.

If the weighted average cost other than fuel at Breed Station for a period of twelve consecutive elapsed months is below 16.7 cents per kilowatt-month by at least 0.5 cent, for each full 0.5 cent that such cost is below 16.7 cents, the bill rendered to Indianapolis Company for the next succeeding month shall be decreased by 0.625 cent per kilowatt of Firm Contract Demand. SECTION 6 - BILLINGS AND PAYMENTS 6.1 Billings and payments for the purposes of effecting settlements under this Service Schedule shall be made in accordance with and subject to the terms and conditions of Article 7 of this agreement. SECTION 7 - TAXES 7.1 It is expressly agreed and made a provision of this Service Schedule that if at any time during the term hereof there should be levied and/or assessed against Indiana Company any direct tax by any taxing authority on the Firm Power and/or Firm Energy manufactured, generated, produced, converted, sold, purchased, transmitted, interchanged, exchanged, exported or imported by Indiana Company, in addition to or different from the forms of such direct taxes now being levied and/or assessed against Indiana Company, or any increase in the rate of such existing or future direct taxes, which Indiana Company could demonstrate to be unduly burdensome to it in the performance of the obligations herein provided, then in such event, the parties shall endeavor to make such an agreement in regard to sharing the burden created by such tax as appears to be equitable and proper under the circumstances. SECTION 8 - DEFERRAL OF EFFECTIVE DATE 8.1 Notwithstanding any of the foregoing provisions of this Service Schedule, in the event Indiana Company as of June 1, 1963, is unable to provide 345,000-volt transmission line facilities suitable for connection to Indianapolis Company's terminal facilities as Hanna Substation, as described in Section 1.02 of Article 1 of this agreement, and sufficiently completed to enable Indiana Company to supply over such facilities Firm Power service as provided for in this Service Schedule, this Service Schedule shall not become effective until June 1 next following the day, or on such day if it should be June 1, that Indiana Company is so able to provide such 345,000-volt transmission line facilities. In the event that this Service Schedule becomes effective after June 1, 1963, as provided for in this subsection 8.1, it shall continue in effect from the date that it so becomes effective to the expiration of a period of ten consecutive years and thereafter for successive periods of one year unless and until terminated as provided for in this subsection 8.1. Either party upon at least thirty months' prior written notice to the other may terminate this Service Schedule at the expiration of said period of ten consecutive years or at the expiration of any successive period of one year.

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 deliver to such party electric energy in amounts up to and including 50,000 kilowatts which 50,000 kilowatts is hereby designated and herein called Emergency Capacity, and shall also deliver any additional electric energy in excess of said amount that it is requested to deliver; provided, however, that neither party shall be obligated to deliver any part of such additional energy which, in its sole judgment, it cannot deliver without interposing a hazard to or economic burden upon its operations or without impairing or jeopardizing the other load requirements of its system; and provided further, that neither party shall be obligated to deliver electric energy in amounts up to and including or in excess of said Emergency Capacity to the other for a period in excess of forty-eight consecutive hours during any single emergency. 2.2 The parties recognize that the delivery of electric energy up to and including the Emergency Capacity 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 system of a party may be suffering an emergency in or on its own system as described in said subsection 2.1, or (b) the system of a party 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 reasonable 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 this 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 this 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 Electric energy delivered under Section 2 above shall be settled for either by the return of equivalent energy or, at the option of the party that supplied such energy, by payment of the out-of-pocket cost--such cost being as of the delivery point or points, as provided for in Section 5.01 of Article 5 of this agreement, taking into account electric losses incurred from the source or sources of such energy to said delivery point or points--to the supplying party of generating or supplying such energy plus ten per cent of such cost. If equivalent energy is returned, it shall be returned at times when the load conditions of the party receiving it are 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. SERVICE SCHEDULE C COORDINATION OF SCHEDULED MAINTENANCE OF GENERATING FACILITIES Under Agreement, dated December 30, 1960, between Indianapolis Power & Light Company and Indiana & Michigan Electric Company SECTION 1 - DURATION 1.1 This Service Schedule, a part of and under agreement, dated December 30, 1960, between Indianapolis Power & Light Company (Indianapolis Company) and Indiana & Michigan Electric Company (Indiana Company) shall become effective on the Interconnection Date as defined in Section 10.01 of Article 10 of this agreement and shall continue in effect throughout the duration of the agreement of which it is a part. SECTION 2 - SERVICES TO BE RENDERED 2.1 In furtherance of the benefits to be realized by the parties by coordinating to the extent practicable the scheduled maintenance, repair, and overhaul of generating facilities in their respective systems and in connection with such scheduled maintenance, repair, and overhaul of generating facilities the parties shall arrange for, deliver, and take electric power and energy in amounts and under conditions as follows; viz.: 2.11 For purposes of this Service Schedule the full twelve months' period commencing on the Interconnection Date shall be the first Maintenance Period and each succeeding full twelve months' period that this Service Schedule is in effect shall be a Maintenance Period. During each Maintenance Period, at different intervals determined as provided for under subsection 2.12 below, each party shall have the right to call for and take delivery of not more than the total of 10,000,000 kilowatt-hours from the other under this Service Schedule. Delivery of such energy, subject to the provisions of this subsection 2.1, may be taken at such times and at such rates of take as the receiving party may elect up to a maximum rate of take of 25,000 kilowatts. 2.12 The Operating Committee shall determine and agree upon the dates of the intervals referred to under subsection 2.11 above during which Indianapolis Company shall deliver any such energy desired by or returnable to Indiana Company and, conversely, the dates of such intervals during which Indiana Company shall deliver any such energy desired by or returnable to Indianapolis Company. Subject to the understanding hereinbelow cited, such intervals shall each consist of single periods of not less than seven consecutive calendar days, and the receiving party's right to call for and take not more than the aforesaid total of 10,000,000 kilowatt-hours during any Maintenance Period shall be restricted to not more than eight such intervals so agreed upon by the Operating Committee during such Maintenance Period. It is understood that during any Maintenance Period each party shall have a total of sixty days during which it shall have the right to call for and take not more than said 10,000,000 kilowatt-hours from the other under this Service Schedule. 2.13 On the day next preceding the first day of an interval as described under 2.12 above and on each day of such interval excepting the last day, at a time determined to be practicable by the Operating Committee, the receiving party shall furnish the other a load schedule for the next calendar day, or for such other twenty-four hour period or periods as may be agreed upon by the Operating Committee. Such load schedules shall show for each clock hour the quantity of energy that the receiving party expects to take from the other at the delivery point or points, as provided for in Section 5.01 of this agreement. SECTION 3 - ANNUAL SETTLEMENT 3.1 It is expected that during a full Maintenance Period one party shall, to the extent practicable, take from the other party the same number of kilowatt-hours, up to the aforesaid 10,000,000 kilowatt-hours specified in Section 2 of this Service Schedule, that such other party has delivered pursuant to said Section 2. If, however, the total kilowatt-hours received by one party during a full Maintenance Period, pursuant to said Section 2, is greater than the total kilowatt-hours delivered by such party during such period and pursuant to said Section 2, the parties shall (1), subject to their mutual agreement, effect the arrangements provided for in subsection 3.11 below or (2), subject to their mutual agreement, effect a combination of the arrangements provided for in subsection 3.11 below and a cash settlement as provided for in subsection 3.12 below or (3) effect a cash settlement as provided for in subsection 3.12 below. 3.11 The Operating Committee shall arrange, if the parties mutually agree that it shall be so arranged, for the delivery of all or any part of the kilowatt-hour difference between the total kilowatt-hours received and delivered by one party during a full Maintenance Period, pursuant to Section 2 of this Service Schedule. Such delivery, to be made by the party receiving such kilowatt-hour difference to the other party, shall be made during the next following Maintenance Period at intervals thereof and in amounts and at rates of delivery to be determined and agreed upon by the Operating Committee, but such delivery shall be excluded from all accounting under this Service Schedule with respect to such following Maintenance Period. 3.12 For the kilowatt-hour difference, or any part thereof if the parties mutually agree to effect a cash settlement for only such part, between the total kilowatt-hours received and delivered by one party during a full Maintenance Period, pursuant to Section 2 of this Service Schedule, the party receiving such kilowatt-hour difference shall pay the other party at a rate per kilowatt-hour determined by dividing (1), one hundred and ten per cent of the aggregate out-of-pocket cost--such cost being as of the delivery point or points, as provided for in Section 5.01 of Article 5 of this agreement, taking into account electrical losses incurred from the source or sources of such energy to said delivery point or points--experienced by the systems of both parties in generating or supplying the aggregate kilowatt-hours delivered during and applicable to such Maintenance Period, pursuant to Section 2 of this Service Schedule, by (2), the number of such aggregate kilowatt-hours. SECTION 4 - MODIFICATION 4.1 Each party, by written notice given to the other party not less than ninety days prior to the end of the second or any subsequent Maintenance Period, may call for a reconsideration of the terms and conditions of this Service Schedule, provided that there shall be no such reconsideration during the first Maintenance Period and no more than one such reconsideration during the second Maintenance Period, and that no subsequent reconsideration shall be made sooner than two years following any previous reconsideration. If such reconsideration is called for, there shall be taken into account any changed conditions, any results from the application of said terms and conditions not foreseen or reasonably foreseeable as of the day first above written or as of the day of conclusion of the next previous reconsideration, if any, and any other factors which might cause said terms and conditions to result in any inequitable division of the benefits of interconnected operation or in an inadequate realization of such benefits. Any modification in terms and conditions agreed to between the parties following such reconsideration shall become effective at the beginning of the Maintenance Period next following the aforesaid ninety-day notice period. SERVICE SCHEDULE D ENERGY TRANSFER Under Agreement, dated December 30, 1960, between Indianapolis Power & Light Company and Indiana & Michigan Electric Company SECTION 1 - DURATION 1.1 This Service Schedule, a part of and under agreement, dated December 30, 1960, between Indianapolis Power & Light Company (Indianapolis Company) and Indiana & Michigan Electric Company (Indiana Company) shall become effective on the Interconnection Date as defined in Section 10.01 of Article 10 of this agreement and shall continue in effect throughout the duration of the agreement of which it is a part. SECTION 2 - TRANSFER ARRANGEMENT 2.1 In carrying out the interconnected operation of their respective systems as provided for under this agreement, energy being received by a portion of one party's system from another portion of its system or from the system of another interconnected company, or energy being delivered by a portion of one party's system to 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 of which the transmission systems of the parties are a part. 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 agreed as follows; viz.: 2.11 Such energy transfer over their respective facilities shall be permitted when such transfer occurs; subject, however, to the understanding 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 transfer occurs to render proper service to its customers, and to render or accept service to or from companies with which it now has or at any time hereafter it may have contractual arrangements to furnish, take, or interchange power or energy, or both. 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 transfer occurs is not affected adversely or jeopardized in meeting its own requirements as described under 2.11 above. In the event the need for such additional transmission facilities become apparent to either of the parties during the duration 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 re-examine conditions relating to energy transfer. In such re-examination, 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 transfer as described under Section 2 of this Service Schedule, except for such amounts of electrical losses as may be incurred because of such energy transfer, is 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 transfer occurs. Power and energy associated with energy transfer, including electrical losses associated therewith, shall be accounted for each clock-hour as provided for under Article 6 of this 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 transfer, 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 transfer is being made. The parties have agreed 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 re-examination and reconsideration of matters pertinent to the establishment of said basic conditions, whenever such re-examination 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. A statement to be prepared by the parties at the end of each calendar month 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. SERVICE SCHEDULE E INTERCHANGE POWER Under Agreement, dated December 30, 1960, between Indianapolis Power & Light Company and Indiana & Michigan Electric Company SECTION 1 - DURATION 1.1 This Service Schedule, a part of and under agreement, dated December 30, 1960, between Indianapolis Power & Light Company (Indianapolis Company) and Indiana & Michigan Electric Company (Indiana Company) shall become effective on the Interconnection Date as defined in Section 10.01 of Article 10 of this agreement and shall continue in effect throughout the duration of the agreement of which it is a part. SECTION 2 - SERVICES TO BE RENDERED Economy Energy 2.1 It is recognized that from time to time each of the parties may have electric energy (herein called Economy Energy) available from surplus capacity either on its own system or from sources outside its own system, or both, and that Economy Energy could be supplied to the other party at a cost that would result in operating savings to such other party. Such operating savings would result from the displacement of electric energy that otherwise would be supplied from capacity either on such other party's system or from sources outside its own system, or both. To promote the economy of electric power supply and to achieve efficient utilization of production capacity, either party, whenever it in its own judgment determines Economy Energy is available, may, but shall not be obligated to, offer Economy Energy to the other party. Promptly upon receipt of any such offer said other party shall notify the offering party of the extent to which it desires to use such Economy Energy, and schedules providing the periods and extent of use shall be agreed upon. Non-Displacement Energy 2.2 It is further recognized that from time to time occasions will arise when the effecting of transactions as provided under subsection 2.1 next above will be impracticable, but at the same time one of the parties may have electric energy (herein called Non-Displacement Energy) which it is willing to make available from surplus capacity either on its own system or from sources outside its own system, or both, that can be utilized advantageously for short intervals by the other party. It shall be the responsibility of the party desiring the receipt of Non-Displacement Energy to initiate the receipt and delivery of such energy. The party desiring such receipt of energy shall inform the other party of the extent to which it desires to use Non-Displacement Energy, and, when ever in its own judgment such other party determines that it has Non-Displacement Energy 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 Economy Energy supplied hereunder shall be considered as displacing electric energy that otherwise would have been generated by the receiving party at its own steam-electric generating stations or any electric energy from third parties mutually agreed to be subject to displacement hereunder. Economy Energy shall be settled for at rates which shall be predicated upon the principle that savings in operating costs to the systems of the parties resulting from the use of Economy Energy shall be divided between the parties as equally as is practicable. Prior to any transaction involving the delivery and receipt of Economy Energy, authorized representatives of the parties shall determine and agree upon the compensation applicable to such transaction. Compensation so agreed upon shall not be subject to later review or adjustment. Non-Displacement Energy 3.2 Non-Displacement Energy delivered hereunder shall be settled for either by the return of equivalent energy or, at the option of the party that supplied such energy, by payment of the out-of-pocket cost--such cost being as of the delivery point or points, as provided for in Section 5.01 of Article 5 of this agreement, taking into account electrical losses incurred from the source or sources of such energy to said delivery point or points--to the supplying party of generating or supplying such energy plus ten per cent of such cost. If equivalent energy is returned, it shall be returned at times when the load conditions of the party receiving it are 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. SERVICE SCHEDULE F SHORT TERM POWER Under Agreement, dated December 30, 1960, between Indianapolis Power & Light Company and Indiana & Michigan Electric Company SECTION 1 - DURATION 1.1 This Service Schedule, a part of and under agreement, dated December 30, 1960, between Indianapolis Power & Light Company (Indianapolis Company) and Indiana & Michigan Electric Company (Indiana Company) shall become effective on the Interconnection Date as defined in Section 10.01 of Article 10 of this agreement and shall continue in effect throughout the duration of the agreement of which it is a part. SECTION 2 - SERVICES TO BE RENDERED 2.1 Either party by giving the other party notice may reserve for periods of not less than one week, i.e., any specified period of seven consecutive days, such electric power (herein called Short Term Power) as the other party may at such time have and is willing to make available as Short Term Power. The party asked to supply Short Term Power shall be the sole judge as to the amounts and periods that its has electric power available that may be reserved by the other party as Short Term Power. 2.11 To reserve Short Term Power, the party desiring such power shall specify in its notice to the other party the number of kilowatts and the period for which it desires to so reserve such power and the desired schedule of delivery of the power so reserved. The party receiving such notice, in a prompt acknowledgment shall signify the extent of its ability and willingness to comply with the provisions of such notice. Any notice or any acknowledgment of such notice that may be given orally initially, if requested by either party, 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. 2.12 During the period that Short Term Power has been reserved as above provided, the party having agreed to supply such power shall deliver electric energy (herein called Short Term Energy) to the other party at the delivery point or points, as provided for in Section 5.01 of Article 5 of this agreement, upon call and in amounts up to the number of kilowatts reserved. However, in the event conditions arise during such period which could not have been reasonably foreseen at the time said power was reserved and such conditions would cause the delivery of Short Term Energy to be burdensome to the supplying party, said party has the right to request the other party to reduce its take of such energy to any amount specified and for any portion of such period. The party so requested shall promptly comply with the request of the other party. 2.13 The Short Term Power billing demand for any week shall be taken as equal to the number of kilowatts reserved for such week as Short Term Power. SECTION 3 - COMPENSATION 3.1 Payments for the supply of Short Term Power and Short Term Energy shall be predicated upon the following rates: 3.11 Demand Charge For the billing demand for each week at the rate of $0.30 per kilowatt for such week. In the event the amount of Short Term Energy taken is reduced upon request of the supplying party, the demand charge for the week during which such reduction is made shall be reduced by $0.06 per kilowatt of reduction for each day during which any reduction is in effect. 3.12 Energy Charge For the kilowatt-hours of Short Term Energy taken, at a rate per kilowatt-hour equal to the out-of-pocket cost--such cost being as of the delivery point or points, as provided for in Section 5.01 of Article 5 of this agreement, taking into account electrical losses incurred from the source or sources of such energy to said delivery point or points--to the supplying party of generating or supplying such energy plus ten per cent of such cost.

Section 2 - SERVICES TO BE RENDERED Economy Energy 2.1 Either party may arrange to purchase from any party of the other system electric energy ("Economy Energy") whenever it is possible to effect a saving thereby and, in the sole judgment of the party requested to supply the same, such energy is available. Economy Energy may also be arranged to be obtained from or delivered to systems interconnected with the parties, but not a party to this Agreement. Prior to each delivery of Economy Energy, the amount and time of delivery and the charge therefore shall be determined by the parties. Non-Displacement Energy 2.2 It is further recognized that from time to time occasions will arise when the effecting of transactions as provided under subsection 2.1 next above will be impracticable but that at the same time one of the parties may have electric energy (herein called "Non-Displacement Energy") which it is willing to make available from surplus capacity either on its own system or from sources outside its own system or both, that can be utilized advantageously for short intervals by the other party. It shall be the responsibility of the party desiring Non-Displacement Energy to initiate the receipt and delivery of such energy. The party desiring such receipt of energy shall notify the other party of the extent to which it desires to use Non-Displacement Energy, and whenever in its sole judgment such other party determines that it has Non-Displacement Energy 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 party purchasing it shall pay the out-of-pocket cost of the party supplying such energy and that the resulting savings to the receiving party shall be equally shared by the supplying and receiving parties. 3.2 When Economy Energy is obtained from or delivered to other systems interconnected with the parties, but 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 which are defined as the difference between (1) what the out-of-pocket cost of the receiving party or system would have been to generate such energy, and (2) the out-of-pocket cost of the supplying party or system providing the energy such allocation shall be made as provided in subsections 3.21 and 3.22 hereinbelow. 3.21 Each party or system participating in the transaction other than the supplying and receiving parties or systems, shall be paid (a) its cost of purchasing the energy supplied, plus (b) its cost of additional transmission losses incurred, plus (c) fifteen per cent of the gross savings remaining after deducting all such payments for transmission losses. 3.22 The supplying party or system shall be paid its out-of-pocket costs of providing the energy, plus one-half of the gross savings remaining after deducting all (b) and (c) payments made under subsection 3.21. The receiving party or system shall be entitled to the other one-half of the gross savings remaining after deducting all (b) and (c) payments made under subsection 3.21. Non-Displacement Energy 3.3 Non-Displacement Energy delivered hereunder shall be settled for either by the return of equivalent energy or, at the option of the party that supplied such energy, by payment of the out-of-pocket cost - such cost being as of the delivery point or points, as provided for in Section 5.01 of said Interconnection Agreement, taking into account electrical losses incurred from the source or sources of such energy to said delivery point or points - of the supplying party in generating or supplying such energy plus ten per cent of such cost. If equivalent energy is returned, it shall be returned at times when the load conditions of the party receiving it are 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.

MODIFICATION NO. 17 TO THE INTERCONNECTION AGREEMENT BETWEEN INDIANAPOLIS POWER & LIGHT COMPANY AND INDIANA MICHIGAN POWER COMPANY 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 Indiana Michigan Power Company ("Buyer") and IPL dated December 30, 1960, as amended (the "Agreement"). WITNESSETH: WHEREAS, IPL and Indiana Michigan Power Company entered into the Agreement on December 30, 1960, 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 B Emergency Service Service Schedule E Interchange Power Service Schedule F Short Term Power Service Schedule I Limited Term Power (Firm) Service Schedule L Peaking Power and Energy and Seasonal Exchange Power and Energy 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 Peaking Power and Energy and Seasonal Exchange Power and Energy, 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, then 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.
