either party or because of scheduled maintenance that has been agreed to by
both parties, the parties shall cooperate so as 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.

                             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

                             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.

Metering

     5.03  Suitable metering equipment at the metering points as provided
in Section 5.02 above shall include electric meters, potential and current
transformers, and such other appurtenances as shall be necessary to give for
each direction of flow the following quantities:  (1)  a continuous
automatic graphic record of both kilowatts and kilovars, (2) an automatic
record of the kilowatt-hours for each clock hour, and (3) a continuous
integrating record of the kilowatt-hours.

     5.04  Measurements of electric energy for the purpose of effecting
settlements under this agreement shall be made by standard types of electric
meters installed and maintained, unless otherwise provided for in this
agreement, by the owner at the metering points as provided under Section
5.02 above.  The timing devices of all meters having such devices shall be
maintained in time synchronism as closely as practicable. The meters shall
be sealed and the seals shall be broken only upon occasions when the meters
are to be tested or adjusted.  For the purpose of checking the records of
the metering equipment installed by one of the parties as hereinabove
provided, the other party shall have the right to install check metering
equipment at the aforesaid metering points.  Metering equipment so installed
by one party on the premises of another party, unless otherwise provided for
in this agreement, shall be owned and maintained by the party installing
such equipment.  Upon termination of this agreement the party owning such
metering equipment shall remove it from the premises of the other party.
Authorized representatives of both parties shall have access at all
reasonable hours to the premises where the meters are located and to the
records made by the meters.

     5.05  The aforesaid metering equipment shall be tested by the owner at
suitable intervals and its accuracy of registration maintained in accordance
with good practice.  On request of either party, a special test may be made
at the expense of the party requesting such special test. Representatives
of both parties shall be afforded opportunity to be present at all routine
or special tests and upon occasions when any readings, for purposes of
settlements hereunder, are taken from meters not bearing an automatic
record.

     5.06  If at any test of metering equipment an inaccuracy shall be
disclosed exceeding two percent, the account between the parties for service
theretofore delivered shall be adjusted to correct for the inaccuracy
disclosed over the shorter of the following two periods: (1) for the
thirty-day period immediately preceding the day of the test or (2) for the
period that such inaccuracy may be determined to have existed. Should the
metering equipment as provided for under Section 5.03 above at any time fail
to register, the electric power and energy delivered shall be determined
from the check meters, if installed, or otherwise shall be determined from
the best available data.

                             ARTICLE 6

                      RECORDS AND STATEMENTS

Records

     6.01  In addition to records of the metering provided for in Article 5
above, the parties shall keep in duplicate such other records as may be
needed to afford a clear history of the various deliveries of electric
energy made by one party to the other and of the clock-hour integrated
demands in kilowatt-hours delivered by one party to the other.  In
maintaining such records, the parties shall effect such segregations and
allocations of demands and electric energy delivered into classes
representing the various services and conditions as may be needed in
connection with settlements under this agreement.  The originals of all such
records shall be retained by the party keeping the records and the
duplicates shall be delivered monthly to the other party except as the
parties may agree upon a different time interval for such delivery.

Statements

     6.02  As promptly as practicable after the end of each calendar month,
the parties shall cause to be prepared a statement setting forth the
electric power and energy transactions between the parties during such month
in such detail and with such segregations as may be needed for operating
records or for settlements under the provisions of this agreement.

                             ARTICLE 7

                       BILLINGS AND PAYMENTS

     7.01  All bills for amounts owed by one party to the other shall be
due and payable on the fifteenth day of the month next following the monthly
or other period to which such bills are applicable, or on the tenth day
following receipt of bill, whichever date be later. Interest on unpaid
amounts shall accrue at the rate of six per cent per annum from the date due
until the date upon which payment is made.  Unless otherwise agreed upon a
calendar month shall be the standard monthly period for the purposes of
settlements under this agreement.

                             ARTICLE 8

the case may be.

     11.03  The sole arbitrator, or the board of arbitrators, shall afford
adequate opportunity to the parties to present information with respect to
the question or questions submitted for arbitration and may request further
information from either or both parties.  The findings and award of the sole
arbitrator or of a majority of the board of arbitrators shall be final and
conclusive with respect to the question or questions submitted for
arbitration and shall be binding upon the parties, provided, that such
findings and award shall not in any way vary the expressed terms of this
agreement or in any way extend the expressed scope and intent hereof.  Each
party shall pay for the services and expenses of the arbitrator appointed by
or for it, if there be a board of arbitrators, and all other costs incurred
in connection with the arbitration shall be paid in equal parts by the
parties hereto, unless the award shall specify a different division of the
costs.

     5.13  Weighted average Fuel Cost - The total of all the components of
               cost at all the Principal Stations chargeable to Account
               No. 501 Fuel during a specified period divided by the
               total millions of Btu in fuel charged to said account at
               all the Principal Stations during such period, expressed
               in cents per million Btu.

     5.14  Weighted average Fuel Consumption - The total Btu in fuel
               charged to Account No. 501 Fuel, at the Principal Stations
               during a specified period divided by the total kilowatt-hour
               net generation at all the Principal Stations during such
               period, expressed in Btu per kilowatthour.

     5.15  Accounts other than Fuel - All of the operating production
               expense accounts for Electric Generation-Steam Power of said
               Uniform System of Accounts other than Account No. 501 Fuel
               as prevailing during January 1961.

     5.16  Capability of Breed Station - The aggregate kilowatt-hours of
               net generation during a clock-hour period that the Breed
               Station is capable of generating at the time of the annual
               peak load of the Indiana Company system with all equipment
               operating at such station.

     5.17  Weighted average cost other than Fuel at Breed Station - The
               total of all the components of cost chargeable to the accounts
               other than Fuel specified in subsection 5.15 above at the

               product of (1) the Capability of the Breed Station during
               such period and (2) the number of months during such
               period, expressed in cents per kilowatt-month.

     5.2  The charges provided for in Section 4 of this Service Schedule
are based upon a weighted average fuel cost of twenty and one-half cents
($0.205) per million Btu at the Principal Stations.  In the event such
weighted average fuel cost for any month is above twenty and one-half cents
($0.205) per million Btu by at least one mill, an additional charge during
the next succeeding month shall be made on the kilowatt-hours of Firm Energy
actually delivered during such succeeding month at a rate of 0.0105 mills
per kilowatt-hour for each full mill increase in such weighted average fuel
cost above twenty and one-half cents ($0.205) per million Btu. In the event
such weighted average fuel cost for any month is less than twenty and
one-half cents ($0.205) per million Btu by at least one mill, the bill
rendered to Indianapolis Company for the next succeeding month shall be
decreased by an amount equal to the kilowatt-hours of Firm Energy actually
delivered during such succeeding month at a rate of 0.0105 mills per
kilowatt-hour for each full mill decrease in such weighted average fuel cost
below twenty and one-half cents ($0.205) per million Btu. The said
adjustment factor of 0.0105 mills shall be subject to adjustment as provided
for in subsection 5.3 of this Service Schedule.

     5.3  The said adjustment factor of 0.0105 mills is based upon a
weighted average fuel consumption of 10,500 Btu per kilowatthour of net
generation.  In the event that improvements in the thermal efficiency of the
presently existing Principal Stations or the addition of any new Principal
Station bring about a reduction in the weighted average fuel consumption for
a period of twelve (12) consecutive months of at least 200 Btu below 10,500
Btu per kilowatthour, the adjustment factor of 0.0105 mills for the next
succeeding month shall be decreased 0.00019 mills for each full 200 Btu that
the weighted average fuel consumption so becomes lower than 10,500 Btu per
kilowatthour.

     5.4  If the weighted average cost other than fuel at Breed Station for
a period of twelve consecutive elapsed months is above 16.7 cents per
kilowatt-month by at least 0.5 cent, for each full 0.5 cent that such cost
is above 16.7 cents, the next succeeding month Indianapolis Company shall
pay 0.625 cent per kilowatt of Firm Contract Demand.  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.

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

     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.

          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.

                         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.

     supplying party, one-sixth of said $0.40 per kilowatt of the
     reduction.  (Except that in no event shall the total of such
     deductions in any week exceed $0.40 per kilowatt.) For each period
     less than one week that Short Term Power is reserved, $0.10 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,
     $0.10 per kilowatt of the reduction; plus

          3.12  for each kilowatt of the reserved Short Term Power that is
     purchased by the supplying party from another system, prearranged in

         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 the Interconnection
Agreement, dated as of the 30th day of December, 1960 between Indianapolis
Power & Light Company (Indianapolis Company) and Indiana and Michigan
Electric Company (Indiana Company), shall become effective as of March 15,
1977, and shall continue in effect throughout the duration of said
Interconnection Agreement of which it is a part.

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.

          per hour for the next day.  Thereafter, the purchasing party
          may, due to unforeseen circumstances, make changes to this
          schedule by giving reasonable notice.

     d)   The availability of Seasonal Exchange Power and Energy and a
          supplying Party's obligation to deliver same to the purchasing
          Party in any hour is contingent upon the ability of the
          supplying Party to first meeting its internal load and its firm
          load commitments as of the effective date of this Service
          Schedule L.  The present firm load commitments of the AEP System
          are as enumerated in Section 2.5 above.

     e)   For the period defined in Section 2.7(a) during which Seasonal
          Exchange Power and Energy is agreed to be exchanged, I&M shall
          supply 50 MWH per hour to IPL during the months of June through

          shall supply 50 MWH per hour to I&M during the months of
          December through February in the winter seasons of 1995/1996,
          1996/1997, 1997/1998 and 1998/1999.

     f)   Seasonal Exchange of Power and Energy may be extended from time
          to time after the period defined in Section 2.7(a) in such
          amount and for such periods as may be mutually agreed upon by
          the parties.

2.8  I&M and IPL shall at all times operate and maintain their respective
generation and transmission systems in a manner consistent with safe,
prudent and efficient operating practices that are generally considered by
the electric utility industry as being prudent utility practice.

SECTION 3 - COMPENSATION

3.1  Demand Charges - IPL shall make monthly payments to I&M for Peaking

     a)   $600,000 from April 1, 1992 through March 31, 1993;

     b)   $1,200,000 from April 1, 1993 through March 31, 1997;

     c)   $1,200,000 from April 1, 1997 through December 31, 1997 if IPL
          chooses to continue service under Service Schedule L pursuant to
          subsection 2.6 above; and

     d)   $1,550,000 from January 1, 1998 through November 30, 1999, if

          pursuant to subsection 2.6 above.

3.2  Energy Charges - IPL shall make monthly payments to I&M for Peaking
Energy delivered during the term of this Service Schedule L.  The monthly
charges will equal the out-of-pocket cost of supplying Peaking Energy
delivered during the month, pursuant to subsection 2.4 above, including all
operating, variable maintenance, tax, transmission losses, the cost as
agreed to by the Operating Committee or replacement of consumed SO2 and
other atmospheric emission allowances, if any, when such allowance programs
become effective, and other expenses incurred which would not have been
incurred if the energy had not been supplied.  Energy charges are subject to
review by the Operating Committee.  However, the out-of-pocket cost for any
hour during which AEP generates or purchases power to meet its obligation to
deliver Peaking Power and Energy to IPL shall not exceed the calculated out-
of-pocket cost of operating a gas turbine plant with a Heat Rate of 11,121
/BUT/KWH during the same month.  The calculation of the out-of-pocket cost
of operating a gas turbine plant shall be made as agreed upon by the
Operating Committee.  The gas cost for this maximum rate calculation will be
equal to the cost experienced by IPL the previous month for its own gas
fired peaking capacity or the cost of natural gas for Indiana as listed in
the table "Average Price of Natural Gas Delivered to Electric Utility
Consumers by State" (current Table 31) in the "Energy Information
Administration/Natural Gas Monthly" for the previous month, if IPL shall not
have operated such generating capacity in the month.  IPL shall inform I&M
of such costs in a timely manner.

3.3  Charges for Seasonal Exchange Power.  There shall be no demand Charge
for Seasonal Exchange Power.  IPL shall make monthly payments to I&M during
the summer seasons and I&M shall make monthly payments to IPL during the
winter seasons, pursuant to Section 2.7(e), for Seasonal Exchange Energy
delivered.  The monthly charges will equal the delivering company's out-of-
pocket cost of supplying such Energy as defined in subsection 3.2 above,
plus the lesser of a) 10% of such out-of-pocket cost or b) 3 mills/KWH.

SECTION 4 -- REGULATORY APPROVAL

4.1  If the Federal Energy Regulatory Commission ("FERC") does not accept
this Service Schedule L for filing within ninety (90) days of its
submission, either Party may terminate this Service Schedule.  If the FERC
requires modification to the rates, terms, or conditions of this Service
Schedule L as a condition of accepting it for filing, either Party may
terminate this Service Schedule.  In the event the Indiana Utility
Regulatory Commission ("IURC") does not authorize IPL to sue one of the
purchase power cost recovery mechanisms requested by IPL, or in IPL's first
general retail electric rate proceeding ("Rate Case") following the
effective date of this Service Schedule L, the IURC disallows recovery of
past Demand Charges paid by IPL hereunder and/or disallows future Demand
Charges hereunder which are fixed, known and measurable for such rate
proceeding, then in any such event, IPL may terminate this Service Schedule
L.

4.2  Notice of any termination under this Section 4 shall be given in
writing by either Party to the other Party within thirty (30) days after
final action (final action being limited to relief available solely from
such regulatory authority without the necessity of filing any petition for
rehearing or reconsideration) of the regulatory authority involved which
imposes such modification, as hereinabove described, or which fails to
provide recovery by IPL of the Demand Charges payable by it under this
Service Schedule L.  This Service Schedule L shall automatically terminate
thirty (30) days after the date of such notice.

                                             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.
