furtherance thereof, the Parties shall, during the term of the Agreement,
continue in service the existing transmission lines and interconnection
facilities and essential terminal equipment, to the extent required for the
purposes of this Agreement. 

ARTICLE 2 - SERVICE CONDITIONS 

2.1              Avoidance of Unauthorized Use and Control of System
Disturbances   Each Party shall have facilities or contractual arrangements
adequate to serve its own load and shall exercise reasonable care to design,
construct, maintain, and operate its Transmission System, in accordance with
Good Utility Operating Practice, and neither Party shall be obligated to receive
or deliver real or reactive power when to do so might introduce objectionable
operating conditions on its Transmission System.  Any Party may install and
operate on its Transmission System such relays, disconnecting devices, and other
equipment as it may deem appropriate for the protection of its Transmission
System or the relief of an Unauthorized Use to its Transmission System.  The
Parties shall maintain and operate their respective Transmission Systems so as
to minimize, in accordance with Good Utility Practice, the likelihood of a
disturbance originating in either Transmission System, which might cause
impairment to the service of the other Party or of any transmission system
interconnected with the Transmission System of the other Party.    

2.2              Interruption of Service   The interconnections provided
under this Agreement, and any service being provided under this Agreement, may
be interrupted or reduced upon such notice as is reasonable under the
circumstances: (a) by operation of automatic equipment installed for power
system protection; (b) after consultation with the other Party, if practicable,
when a Party deems it desirable for installation, maintenance, inspection,
repairs or replacements of equipment; or (c) at any time that, in the sole
judgment of the interrupting Party, such action is necessary to preserve the
integrity of, or to prevent or limit any instability on, or to avoid or mitigate
an Unauthorized Use of its Transmission System.   

2.3      Operating Responsibilities   The Parties agree to operate and
maintain their Transmission System, including the transmission equipment and
facilities, in a manner consistent with Good Utility Practice in order to permit
the Parties to operate their respective Transmission System as required by this
Agreement at their respective cost. Operating arrangements for facility
maintenance of this Agreement shall be coordinated between operating personnel
of the AEP system control center and operating personnel of the IPL system
control center.  Except as may be necessary and appropriate in an emergency, all
operating arrangements shall be coordinated with, and consistent with, the
practices of their respective RTO.    

2.4       Energy Losses   The energy losses on the interconnected facilities
shall be assigned to the appropriate Party based on the metering points of the
interconnected facilities or according to procedures developed by the Operating
Committee and subject to any requirements of their respective RTO.

that all costs paid by a Party to the other Party, for the establishment,
discontinuance or modification of an Interconnection Point, shall be non-taxable
contributions to capital, and shall not be taxable as contributions in aid of
construction (“CIAC”). If federal or state income taxes are imposed upon the
Party with respect to such payments paid by the other Party as a CIAC by the
Internal Revenue Service (“IRS”) and/or a state department of revenue (“State”),
the Party paying the CIAC shall reimburse the other Party for the tax effect of
such CIAC computed in accordance with FERC rules and including any interest and
penalty charged to the Party by the IRS and/or State.

Applicable Laws and Regulations, each (the “Indemnifying Party”) shall
indemnify, save harmless, and defend the other Party from and against any
losses, liabilities, costs, expenses, suits, actions, claims, and all other
obligations arising out of injuries or death to persons or damage to property
caused by or in any way attributable to the ownership or operation of the
Transmission System of the Indemnifying Party, except that the Indemnifying
Party’s obligation to indemnify the other Party shall not apply to the extent of
any liabilities arising from the other Party’s negligence, recklessness or
intentional misconduct or that portion of any liabilities that arise out of the
other Party’s contributing negligent, reckless or intentional acts or
omissions.  Further, to the extent that a Party’s immunity as a complying
employer, under the worker’s compensation and occupational disease laws, might
serve to bar or affect recovery under or enforcement of the indemnification
otherwise granted herein, each Party agrees to waive its immunity.  For the
purposes of this Article 7.1 only, the term “Party” shall include the Party’s
directors, officers, employees, Affiliates and agents.   

7.2       Limitation of Damages   No Party nor any
of its Affiliates, members, managers, shareholders, officers, directors,
employees, agents, successors or assigns shall be liable under this Agreement,
whether in contract, tort (including negligence and strict liability) or
otherwise, to the other Party or any of its Affiliates, members, managers,
shareholders, officers, directors, employees, agents, successors or assigns for
incidental, punitive, special, indirect, multiple, exemplary or consequential
damages (including, without limitation, attorneys’ fees, litigation costs, lost
profits or revenues, or loss of good will) connected with or resulting from
performance or non-performance of this Agreement.   

7.3       Fines   

(a)        Except as set forth in Sections 7.3(b),
any fines, penalties or other costs incurred by either Party or such Party’s
agents, employees or subcontractors for non-compliance by such Party or its
agents, employees or subcontractors with the requirements of any Applicable Laws
and Regulations or Governmental Authorities, will not be reimbursed by the other
Party but will be the sole responsibility of such non-complying Party.   

(b)        If such fines, penalties or other costs
are assessed against a Party (the “Penalized Party”) by any Governmental
Authority due to the non-compliance by the other Party with Applicable Laws and
Regulations or requirement of a Governmental Authority, the other Party will
indemnify and hold harmless the Penalized Party against any and all losses,
liabilities, damages and claims suffered or incurred because of the failure of
the other Party to comply therewith, subject to refund in the event that the
Penalized Party or other Party prevails in any contest of the fines, penalties
or other costs.  The other Party will also reimburse the Penalized Party for any
and all legal or other expenses (including attorneys’ fees) reasonably incurred
by the Penalized Party in connection with such losses, liabilities, damages and
claims.   

(c)        In the case of Section 7.3(b), either
Party will, upon written notice to the other Party, have the right to reasonably
contest in the name of either or both Parties, as required, or to require the
other Party to reasonably contest the assessment of such fines, penalties or
costs, and the Party requesting such contest will be responsible for any costs
and expenses (including the costs and expenses of the other Party) relating to
such contest. 

ARTICLE 8 - ARBITRATION 

8.1       Submission to Arbitration In the event of
disagreement between the Parties with respect to (1) any matter herein
specifically made subject to arbitration, (2) any question of operating practice
involved in the performance of this Agreement, (3) any question of fact involved
in the application of provisions of this Agreement, or (4) the interpretation of
any provision of this Agreement, the matter involved in the disagreement shall,
upon demand of either Party, be submitted to arbitration in the manner
hereinafter provided. The arbitration shall be governed by the Federal
Arbitration Act, 9 U.S.C. Sections 1 et seq., and judgment upon the award rendered by
the arbitrator(s) may be entered by any court having jurisdiction thereof. An
offer of such submission to arbitration shall be a condition precedent to any
right to institute proceedings at law or in equity concerning such matter. 

8.2       Appointment of Arbitrators   The Party
calling for arbitration shall serve notice in writing upon the other Party,
setting forth in detail the subject or subjects to be arbitrated, and the
Parties thereupon shall endeavor to agree upon and appoint one person to act as
sole arbitrator.  If the Parties fail to agree on an arbitrator within a period
of fifteen (15) days from the receipt of the original notice, the Party calling
for the arbitration shall, by written notice to the other Party, call for
appointment of a board of arbitrators skilled with respect to matters of the
character involved in the disagreement, naming one arbitrator in such notice. 
The other Party shall, within ten (10) days after the receipt of such call,
appoint a second arbitrator, and the two arbitrators so appointed shall choose
and appoint a third arbitrator.  In case such other Party fails to appoint an
arbitrator within said ten (10) days, or in case the two so appointed fail for
ten (10) days to agree upon and appoint a third, the Party calling for the
arbitration, upon five (5) days’ written notice delivered to the other Party,
shall seek appointment the second or third arbitrator, as the case may be, from
and pursuant to the rules of the American Arbitration Association (“AAA”) for
commercial arbitration.  No arbitrator named by a Party or, as the case may be,
the AAA, shall have been employed previously by either Party or have a direct or
indirect interest in either Party or the subject matter of the arbitration.   

8.3       Arbitration   

(a)                Except as otherwise provided for
herein to the contrary, arbitration proceedings shall be conducted in accordance
with the commercial arbitration rules of the AAA to the extent not inconsistent
with the rules herein specified.   

(b)               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.    

(c)                The validity, construction and
interpretation of this Article 8, and all procedural aspects of the arbitration
conducted pursuant hereto shall be decided by the arbitrator(s).  In deciding
the substance of the Parties' claims, the arbitrator(s) shall refer to the
governing law referenced in this Agreement.  It is agreed that the arbitrator(s)
shall have no authority to award treble, exemplary or punitive damages of any
type under any circumstances whether or not such damages may be available under
state or federal law, or the rules of the AAA.  The arbitrator(s) shall have the
right only to interpret and apply the terms and conditions of this Agreement,
but may not change any term or condition of this Agreement, deprive either Party
of any right or remedy expressly provided hereunder, or provide any right or
remedy that has been excluded hereunder.    

(d)               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.  To the fullest extent permitted by law,
any arbitration proceeding and subsequent arbitration award shall be maintained
in confidence by the Parties.   

(e)            
Each Party shall pay for the services and expenses of the arbitrator appointed
on its behalf.  If there is a board of arbitrators, all costs incurred in
connection with the arbitration shall be paid in equal parts by the Parties,
unless the award shall specify a different division of the costs.

 ARTICLE 9 - TERMS AND TERMINATION OF
AGREEMENT 

9.1       Terms and Termination   This Agreement shall be effective as of the
date first written above, or such later date as the last necessary regulatory
approval hereof shall be obtained (unless an earlier date is specified by the
regulatory authority having jurisdiction), and shall remain in effect until the
date falling on the tenth (10th) anniversary of the date hereof (the “Initial
Term”) and, thereafter, for successive twelve (12) month periods (“Renewal
Terms”).  Either Party may terminate this Agreement after the Initial Term by
providing to the other Party at least twelve (12) months’ advance written notice
of its intent to terminate this Agreement, in which case this Agreement shall
terminate at the end of such twelve (12) month notice period without regard to
the expiration of any Renewal Term.  Notwithstanding the above, this Agreement
may be terminated earlier (a) if the Parties mutually agree or (b) as otherwise
expressly provided for in this Agreement.   

9.2              Default; Remedies of Parties Upon Default   

(a)        Either Party shall be in default under this Agreement if it fails
to perform any of its material duties or obligations under this Agreement, and
such failure continues for thirty (30) days after written notice thereof from
the other party; provided, that if such failure (other than the failure to make
payment of any amounts due and payable hereunder) is not capable of being cured
within such thirty (30) days period with the exercise of Due Diligence, then
such cure period shall be extended for an additional reasonable period, not to
exceed thirty (30) days, so long as the defaulting Party is exercising Due
Diligence to cure such failure.   

(b)        Upon a default by a defaulting Party, the other Party may, at its
option, (i) take action to terminate this Agreement by providing written notice
of termination to the defaulting Party, Midwest ISO, PJM and FERC; provided,
that any such terminating shall not take effect until FERC approval, if any is
required by Applicable Laws and Regulations, is obtained, and/or (ii) take any
other action at law or in equity as may be permitted under this Agreement to
enforce the performance or observance of any rights, remedies, duties,
obligation or liabilities under this Agreement.   

(c)        No remedy conferred by any provision of this Agreement is intended
to be exclusive of any other remedy and each and every remedy shall be
cumulative and shall be in addition to every other remedy given hereunder or now
or hereafter existing at law or in equity or by statute or otherwise.  The
election of any one or more remedies shall not constitute a waiver of the right
to pursue other available remedies. 

ARTICLE 10 - REGULATORY AUTHORITIES 

10.1          Regulatory Authorities   This
Agreement is made subject to the jurisdiction of any Governmental Authority
having jurisdiction over the Parties, the Transmission Systems of the Parties,
this Agreement or the subject matter hereof.  Nothing contained in this

furnishing service under this Agreement to unilaterally make application to FERC
for a change in rates, charges, classification, service or any rule, regulation
or contract relating thereto under Section 205 and 206 of the Federal Power Act
and pursuant to the FERC’s Rules and Regulations promulgated thereunder.   

10.2          Adverse Regulatory Change   The
Parties agree to jointly submit and support the filing of this Agreement with
the FERC.  Any changes or conditions imposed by the FERC or any other
Governmental Authority with competent jurisdiction in connection with such
submission or otherwise in respect of this Agreement, any of which are
unacceptable to a Party after the Parties’ good faith attempt to negotiate a
resolution to such objectionable change or condition, shall be cause for
termination of this Agreement upon thirty (30) days’ prior written notice by the
non-consenting Party to the other Party.   

ARTICLE 11 - CANCELLATION OF PRIOR AGREEMENTS 

11.1     Cancellation of Prior Agreements   When
this Agreement becomes effective pursuant to Article 9 of this Agreement, this
Agreement shall cancel and supersede in their entirety the 1960 Agreement, 1968
Agreement, 1973 MOA, and the 1985 Agreements.   

ARTICLE 12 - GENERAL

  12.1       Force Majeure   No Party shall be
in default in respect to any obligation hereunder because of Force Majeure.  A
Party unable to fulfill any obligation by reason of Force Majeure shall use Due
Diligence to remove such disability with appropriate dispatch. Each Party
shall:  (a) provide prompt written notice of such Force Majeure event to the
other Party which notice shall include an estimate of the expected duration of
such event; and (b) attempt to exercise all reasonable efforts to continue to
perform its obligations under this Agreement.   

12.2     Waivers   Any waiver at any time by either
Party of its rights with respect to default under this Agreement, or with
respect to any other matter arising in connection with this Agreement, shall not
be deemed a waiver with respect to any subsequent default or matter.  Any delay,
short of the statutory period of limitation, in asserting or enforcing any right
under this Agreement, shall not be deemed a waiver of such right.   

12.3     Liability   

(a)        No Party shall be liable for the failure
of the other Party to perform its obligations hereunder. Nothing in this
Agreement shall be construed to create or give rise to any liability on the part
of Midwest ISO and PJM and the Parties expressly waive any claims that may arise
against Midwest ISO and PJM under this Agreement.   

(b)        The Parties acknowledge and understand
that the signatures of the authorized officers of Midwest ISO and PJM on this
Agreement is for the limited purpose of acknowledging that representatives of
Midwest ISO and PJM have read the terms of this Agreement.  The Parties, Midwest
ISO and PJM further state that they understand that FERC desires that the
Parties keep Midwest ISO and PJM fully apprised of the matters addressed herein
as well as any reliability and planning issues that may arise under this
Agreement, and that the signature of the PJM officer or the Midwest ISO officer
shall not in any way be deemed to imply that Midwest ISO and PJM are taking
responsibility for the actions of either Party, that Midwest ISO and PJM have
any affirmative duties under this Agreement or that Midwest ISO and PJM is
liable in any way under this Agreement.   

12.4     Audit Rights   Each Party shall have the

METERING AND METERING POINTS

1.1              Metering Points   Electric power
and energy  across an Interconnection Point shall be measured by suitable
metering equipment provided by the Parties at the metering points as described
below; and at such other points, voltages, and ownership as may be agreed upon
by the Parties.   Existing Interconnection Points   

1.1.1        IPL shall, at its sole cost, install,
own, operate and maintain or cause to be installed, owned, operated and
maintained, as the case may be, the following metering equipment:    

(a)                Sunnyside Metering Point: 345 kV
metering equipment installed at IPL’s Sunnyside 345 kV Station for the Fall
Creek-Sunnyside Interconnection Point (see Figure 2, Appendix I).

maintained, as the case may be, the following metering equipment:  

 (a)                Breed Metering Point: 345
kV metering equipment installed at AEP’s Breed 345 kV Station for the
Breed-Petersburg/Wheatland Interconnection Point (see Figure 1, Appendix I). 

  1.2              Metering Equipment   Suitable and
reliable metering equipment of revenue quality shall be installed at each of the
existing and future Interconnection Points, as described under Section 1.1
above, and shall include potential and current transformers, revenue meters,
test switches and such other equipment as may be needed.  The metering design
and functionality established by this Appendix II shall serve as a guideline for
all new interconnection metering installations, including any modification,
addition or upgrade to any of the existing metering equipment after the date of
this Agreement. As such, a Party may deviate from this metering design and
functionality with the other Party’s consent, which shall not be unreasonably
withheld, conditioned or delayed.   

1.2.1        General Requirements   All metering
quantities shall be measured at the Interconnection Point and its metering
accuracy shall meet the required metered standards of IPL, PJM, Midwest ISO and
AEP. The Parties may agree by amendment to this Agreement to install metering at
locations other than the Interconnection Points; however, measured metering
quantities shall be compensated for losses to the Interconnection Point,
provided, however, that the Parties shall exercise reasonable efforts to avoid
such compensating metering installations. Based upon mutual agreement between
the Parties, metering can be installed at a location different from the
Interconnection Point; provided, however, measured metering quantities shall be
compensated to the Interconnection Point.   

All reasonable costs for meter changes or meter
upgrades requested by a Party, shall be borne by the requesting Party, unless
agreed otherwise. 

1.2.2    Industry Standard Requirements  
            At least (N-1) metering elements will be used to measure all real
and reactive power crossing the Interconnection Points, where N is the number of
wires in service including the ground wire.  The metering equipment (consisting
of instrument transformers, meters, sockets, and test switches) shall be
installed, calibrated, and tested (at the requesting Party’s expense) in
accordance with the latest approved version of (but not limited to) the Standard
Documents listed below, including the standard testing procedures and guidelines
of the Party that owns the metering equipment: 

ANSI C12.1 :              Code For Electricity
Metering 
ANSI C12.7 :              Requirements for Watt-Hour Meter Socket
 ANSI

ANSI/IEEE C57.13:    Standard
Requirements for Instrument Transformers

To the extent that the above requirements conflict
with the manuals, standards or guidelines of the applicable Regional Reliability
Organization regarding interchange metering and transactions, the manuals,
standards and guidelines of such Regional Reliability Organization shall
control. 

1.2.3    Metering Equipment Maintenance And Testing
  Upon installation and unless otherwise specified, the meters shall be
inspected and tested in accordance with the latest applicable ANSI Standards and
at least annually, or at any other mutually agreed frequency thereafter.  More
frequent meter tests can be performed at the request of a Party; however, the
test will be performed at the requesting Party’s expense if the meter is found
to be within the established ANSI tolerances.  The Party that owns the metering
shall inform the other Party with at least two (2) weeks’ advance notice, of
impending metering tests, and invite the other Party to attend and witness the
tests.   Metering accuracy shall be maintained at three tenths of one percent
(0.3%) accuracy or better, and the meter test shall require a meter standard
with accuracy traceable to the National Institute of Standards and Technology
(“NIST”).   If at any test of metering equipment an inaccuracy shall be
disclosed exceeding two percent (2%), the account between the Parties shall be
adjusted to correct for the inaccuracy disclosed over the shorter of the
following two periods:  (1) for the 30-day period immediately preceding the day
of the test, or (2) for the period that such inaccuracy may be determined to
have existed.  No meter shall be left in service if the percent accuracy error
is found to be more than plus or minus one percent (+/-1%).     The Party that
owns the metering equipment shall maintain records that would demonstrate
compliance with all meter tests and maintenance, and that they are  conducted in
accordance with Good Utility Practice for the life of the Interconnection
Point.  The non-owning Party shall have reasonable access to such records. If
metering equipment fails to function, the energy registration shall be
determined from the best available data, including the check metering, if
applicable. The Instrument Transformers (“IT”) shall also be inspected and
maintained based on Article 1.2.2 of this Appendix II, and existing standards
and practices of the Party that owns the metering equipment. 

1.2.4        Current Transformer Requirements   Each
metering point shall have a dedicated set of metering class current
transformers.  Unless otherwise agreed by the Parties, all metering shall be
type 3.0 element metering, and have three (3) metering accuracy current
transformers.   Current transformers shall meet or exceed an accuracy class of
0.3% (as defined in IEEE C57.13), or better. Current transformers shall comply
with the minimum BIL rating as specified in standards IEEE C57.13 and ANSI
C12.11.    The mechanical and thermal short term current ratings of the current
transformer shall exceed or withstand the available fault current, while the
secondary burden of the current transformer shall not exceed its stated name
plate burden rating. 

1.2.5       Voltage Transformers Requirements   Each
metering point shall have a dedicated set of metering class of voltage
transformers.  Unless otherwise agreed upon by the Parties, all metering shall
be type 3.0 element metering, and have three (3) metering accuracy voltage
transformers.   Voltage transformers shall meet or exceed an accuracy class of
0.3% (as defined in IEEE C57.13).  The secondary of the voltage transformer
shall be exclusively used for the meters only, so as not to exceed the secondary
burden of the stated voltage transformer’s nameplate burden rating.  Voltage
transformers with two separate secondary windings may have one winding dedicated
to the meters and the other winding used for the relaying or metering.  The
nameplate burden rating on either winding must not be exceeded.   Voltage
transformers shall comply with the minimum BIL rating as specified in standards
IEEE C57.13 and ANSI C12.11.   

1.3       Remote Meter Access and Data
Communications   For Interconnection Points not designated as normally open, and
for normally open Interconnection Points, the Party that owns the metering
equipment at such Interconnection Points, unless otherwise mutually agreed,
shall be responsible for installation of the communications facilities
(typically consisting of a telephone circuit and modems) for remotely accessing
the meter. The Owning Party shall also be responsible for operation and
maintenance, and on-going monthly costs of the communication facilities. 

1.3.1    Remote Billing Data Retrieval   The Owning
Party shall provide appropriate communication capability of electronic remote
interrogation of the billing data in a manner that is compatible with commonly
used billing data systems.    

1.3.2    Real Time Communications   Meters shall be
capable of communicating with DAS equipment such as a Remote Terminal Unit
(“RTU”) to provide the following real time bi-directional power and energy
data:  instantaneous power flows, per phase and three-phase averaged RMS
voltages, per phase and three-phase averaged RMS currents and frequency with at
least two decimal points.   

1.3.3    Energy Flow Data   A continuous
accumulating record of active and reactive energy flows shall be provided by
means of the registers on the meters.   The deployed meter(s) shall be capable
of providing bi-directional energy data flow in either kyz pulse signals format,
or accumulated counters to RTU.  The Parties shall share the same data register
buffers regardless of the types of employed data communication methods.  If the
accumulation counter method is used, only one Party shall be responsible for
freezing the accumulator buffers and Party owning of the metering equipment
shall freeze them.  The accumulator freezing signals shall be synchronized to
Universal Coordinated Time (“UCT”) within 1/ 2 seconds.  

1.4       Metering Device Requirements   All meters
shall be programmable and capable of measuring, recording, and displaying
bi-directional active and reactive energy and four quadrant power quantities. 
Also, the meters shall be programmable for compensating for power transformer
and line losses. The meters may preferably have at least one serial
communication, one Ethernet port, hard-wired “kyz” pulse output, and internal
modem for data communication.    The meters’ internal clocks and real-time DAS
equipment shall be synchronized with UCT with at least 10 milliseconds
resolution.  The GPS clock receiver used at each Interconnection Point, shall be
capable of providing unmodulated IRIG-B signals to support the UCT time synch
requirement.   

1.5       Redundant Installation   Future
interconnection metering shall have a primary and a backup meter.  The revenue
meters shall preferably be powered by the station control battery with an
automatic backup power throw-over scheme to one of the phases available from the
metering potential transformers.  

 1.6       Meter Access   A Party whose
metering equipment is located within a station owned by the other Party shall
have reasonable access to the metering equipment for purposes of meter reading,
inspection, testing, and other such valid operating purposes.  Such access shall
not be unreasonably withheld.  

 1.7       Meter Removal   Upon termination of
this Agreement or when the metering is no longer needed, the Party owning the
meter equipment in another Party’s station shall remove the metering equipment
from the premises of the other Party within one (1) year after termination or
within one year after the Party owning the meter equipment determines that the
interchange metering is no longer needed. 

APPENDIX III 

DAS EQUIPMENT: OWNERSHIP, INSTALLATION AND
MAINTENANCE   

1.1       Need for Data Acquisition Provisions   In
recognition that the coordination of the system operations by the Parties may be
facilitated by the sharing of power flow and other real time information from
meters and other equipment at the Interconnection Points, the Parties may agree
to cooperate on the installation and operation of data acquisition system
(“DAS”) equipment including remote terminal units (“RTUs”), meters, MW/MVAR and
volt transducers, telecommunication devices, lease lines, etc., at points which
shall from time to time be mutually agreed upon.  Therefore, the Parties
establish this Appendix III to govern the general principles of such DAS
arrangements. DAS arrangements modifying these general principles shall be
provided in an amendment to this Agreement. 

For purposes of this Appendix III, the term “Other
Party” means a Party that wishes to obtain information from an Owning Party
through the installation of DAS equipment. 

The Owning Party’s RTU or equivalent devices may be
shared by the Other Party. Therefore, the RTU shall support multiple dedicated
communication ports with mutually agreed upon communication protocols.  If a
backup telemetry system or data is required by the Other Party for its own use,
the Other Party shall be responsible for installing and/or maintaining the field
devices and associated telecommunication system at its cost. Where there are
protocol restrictions because of existing legacy systems, the owning Party shall
offer industry standard protocols such as DNP 3.0 or ICCP.  If a proprietary
communication protocol is to be used solely for one Party, the Party requesting
use  of such protocol shall be responsible for the cost  of adding the
customized communication protocol to the RTU.    

The following real time data shall be provided  to
each Party as minimum requirements: Three phase bi-directional energy flows
(e.g., MWH, MVARH), Three phase instantaneous power flows (e.g. MW, MVAR), per
phase RMS voltages, per phase RMS currents, and frequency measurement with at
least two decimal points resolution. In addition to the real time data, the
status of all switching devices associated with the interconnection circuit(s)
shall be provided. For the energy flow data, either or both accumulated data or
hourly interval data shall be provided based on mutually agreed formats.  If
accumulated data is used, the Party owning the RTU will freeze the accumulated
data buffers at the top of each hour and the Other Party will read the frozen
data.  This shall be accomplished in a manner providing for both Parties to have
the same accumulator data readings even though the accumulator data reading
frequencies may not be synchronized. 

1.1.1    The DAS equipment covered herein shall be
associated with the interconnection metering points specified in Appendix II. 
When the Other Party requests additional data, and/or DAS equipment upgrade, the
Parties shall cooperate with each other, based on Good Utility Practice. Unless
otherwise mutually agreed, the Other Party will bear the cost associated with
such requests. This Agreement shall be amended, from time to time, to revise
Appendix III whenever new data acquisition installations are established (new
Interconnection Point) or existing installations are upgraded or deactivated. 

1.1.2    Commissioning Test Procedures 

When new interconnection metering and/or DAS
equipment is installed, replaced or upgraded, a commissioning test shall be
performed based on mutually agreed test procedure. Before the equipment is
officially placed in service, the following processes shall be followed, as a
minimum requirement: 

(a)        The Owning Party shall inform the Other
Party of the commissioning test.               (b)        The Owning Party will
provide a three-way conference call between the interconnection site and
Transmission System control centers of both Parties.                (c)       
Bidirectional test currents shall be injected to the interconnection energy
meter and the instantaneous analog data values displayed by the meter shall be
checked against the corresponding readings received at each control center  
This verification test will be made at the 0, 2.5 and 5 Amp cases, and with
unity and 50% power factors.               (d)        The pulse accumulator
counter data shall be tested in the same manner and the accumulator freeze
functionality shall be verified.               (e)        A “roll-over” count
test may be performed for each accumulator data point  in order to verify the
“roll-over” count is properly processed by both controls centers to verify the
data. 

1.2       New DAS Arrangement   Upon approval of the
Operating Committee, the Parties shall amend this Agreement to revise this
Appendix III to provide the details of DAS arrangements that may have been
established for the mutual benefit of the Parties for new or existing
Interconnection Points, including the ownership of specific DAS equipment and
any mutually agreed provisions different from or in addition to the arrangements
specified in this Agreement.  Any such amendment shall address such additional
details as the Parties’ responsibilities for the provision and installation of
equipment, equipment location, ownership, project scheduling, testing and
commissioning, maintenance, and cost reimbursement, if applicable.    

1.3       Ownership, Installation and Maintenance of
New DAS Equipment   The installation of such DAS equipment, as described in
Article 1.2 of this Agreement, shall be paid for by the Owning Party, unless it
is mutually agreed otherwise to share in the cost; provided, however, the Owning
Party shall have the responsibility to install all DAS equipment. 

1.3.1    The Owning Party shall provide, install,
own and maintain the relays, transducers, wiring, protection equipment and
associated materials (“Owning Party Equipment”) required  to support the
installation of the Other Party’s data acquisition equipment (“Other Party’s
Equipment”).  Provided, however, that if the Interconnection Point is
established for the benefit of and at the request of a Party, the Party
benefiting and requesting the Interconnection Point shall install, own and
maintain the DAS equipment arrangement and shall provide access to the DAS data
to the non-requesting Party. Equipment that is shared in common between the
Owning Party and the Other Party (such as duplicating relays, test switches,
etc.) shall likewise be provided, installed, owned and maintained by the Party
on whose property the shared equipment is located and shall be part of the
Owning Party’s Equipment, unless agreed otherwise. Unless otherwise mutually
agreed, each Party will maintain its own equipment on its side of the
Interconnection Point. 

1.3.2    The Other Party shall provide the Owning
Party documents listing and describing the Other Party’s Equipment that the
Other Party will supply for installation by the Owning Party.  These documents
will generally consist of a hardware list and detailed drawings and/or circuit
diagram.  If the owning Party does not stock the DAS equipment or other
components specified by the Other Party, then the Other Party will supply the
necessary components including spare parts.  The owning Party reserves the right
to refuse to install any material supplied by the Other Party that has not been
approved by the owning Party for use in its installations. The Owning Party
assumes no liability whatsoever in refusing such material or with respect to
material the Other Party thereafter provides for the Owning Party’s
installation.   

1.3.3    The Other Party shall provide, own and
maintain as part of the Other Party’s Equipment, the data communication
circuits, including any necessary data circuit protection equipment, and be
responsible for the costs of such circuit.  Where deemed appropriate by the
owning Party, the Other Party personnel shall be permitted to work independently
on its equipment.  Generally, however, work performed by the Other Party’s
personnel shall be performed under the supervision of the Owning Party
personnel, unless such equipment is located outside or is only accessible from
outside the Owning Party’s facilities. 

1.3.4    Unless otherwise mutually agreed, the
Owning Party will provide station battery power to the DAS equipment at 48, 125,
or 250 Volt DC, via a DC circuit (fused or circuit breaker) at 15, 5, or 5
ampere, respectively.  Under no circumstances shall the Other Party connect
either the positive or negative side of this circuit to ground.  The Other
Party’s Equipment shall be connected to the station’s grounding conductor
through the Owning Party’s breaker control panel.  The Owning Party’s shall
provide station service power for the data acquisition equipment via a 115 V,
60Hz with a 15 ampere (fused or circuit breaker) circuit. 

 

1.4       Location and Site Access   The Owning
Party shall permit the Other Party to locate its data acquisition equipment and
data circuit protection equipment in the Owning Party’s station control
building, if adequate space exist or is available, or outside the Owning Party’s
station switchyard, if no control building is available.  In choosing equipment
location, consideration shall be given to equipment security, protection and
access needs of  both Parties.  In cases where escorted access to the station
control house or outdoor equipment is required, the Other Party shall notify the
Owning Party at least 24 hours prior to any planned visit.  If access is needed
on a short notice, the Parties shall endeavor to arrange such visits by mutual
agreement.  The Owning Party shall not unreasonably withhold access to the
equipment to the Other Party; provided, however, the Owning Party may deny
access based upon safety considerations, operating condition or other relevant
criteria.  

1.5       Proprietary and Confidential Information  
Except as may be required by an RTO or Regional Reliability Organization, the
Parties shall treat all shared telemetry information received via telemetry from
each other as confidential and proprietary and shall take such precautions as
may be reasonable and necessary to prevent such information from being made
known or disclosed to any person or entity except in accordance with this
Agreement.  However, provided, that if a Party is required by law, legal process
or action of a Governmental Authority to disclose any information, such Party
shall promptly notify the Other Party of such requirement so that action, deemed
appropriate in the circumstances, may be taken to protect confidential and
proprietary information against disclosure. 

1.6       Cost Estimate, Billing and Payment   Prior
to the installation of the Other Party’s equipment, both the Owning Party and
the Other Party shall prepare an estimate of the costs associated with such
installation.  All billings and payments terms and conditions, billing disputes
and resolutions shall be handled pursuant to Article 5 of this Agreement.

    2.02  Inasmuch as the specific services to be

rendered in furtherance of such purpose will vary from

time to time while this agreement is in effect, 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

mutually agreed upon from time to time between the

parties.  Such service schedules, until and unless

changed by such mutual agreement, shall be those provided

by Section 2.03 hereof.  Each such service schedule,

while in effect, shall be deemed a part of this

agreement.

    2.03  The respective service schedules designated:

        1.  Service Schedule A - Emergency Service

                       ARTICLE 3

                   SERVICE CONDITIONS

Control of System Disturbance

    3.01  The parties hereto 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

    3.02  It is intended that neither party hereto shall

be obligated to deliver kilovars for the benefit of the

other party; also that neither party shall be obligated

to receive kilovars when to do so may introduce

objectionable operating conditions on its system.  The

Operating Committee shall be responsible for the

establishment from time to time of operating procedures

and schedules, in respect of carrying kilovar loads by

one system for the other in order to secure adequate

service and economical use of the facilities of both

systems and in respect of proper charges, if any, for the

use of facilities carrying kilovar loads.  In discharging

such duties the Operating Committee shall recognize that

in the transmission and delivery of power and energy

hereunder the carrying of kilovar loads by either of the

parties, in harmony with sound engineering principles of

transmission operation with their systems interconnected,

is subject to numerous variables contingent upon loading

and operating conditions existing simultaneously on both

of their systems.  The operating procedures and schedules

so set up by the Operating Committee shall be in accord

with such principles and shall require each of the

parties to carry kilovar loads at such times and in such

amounts as will be equitable to both parties.

Control of Unscheduled Power Deliveries

    3.03  The parties hereto shall exercise reasonable

foresight in carrying out all matters related to the

providing and operating of their respective electric

power resources so as to minimize to the extent

practicable deviations between actual and scheduled

deliveries of electric power and energy between their

systems.  The parties shall provide and install on their

respective systems such communication and telemetering

facilities as are essential to so 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 4.01 of this

agreement, taking into account electrical losses incurred

from the source or sources of such energy to said

delivery point or points) 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 4

               DELIVERY POINTS, METERING

                  POINTS AND METERING

Delivery Points

    4.01  All electric energy delivered under this

agreement shall be of the character commonly known as

three-phase sixty-cycle energy, and shall be delivered at

the Interconnection Point, as defined under Section 1.03

hereof, at a nominal voltage of 138,000 volts and at such

other points and voltages as may be agreed upon by the

parties hereto.

Metering Points

    4.02  Electric Power and energy supplied under this

agreement shall be measured by suitable metering

equipment, having appropriate voltage rating, to be

installed, owned and maintained at the metering point or

points by the party in each case, as provided below:

       4.021  At the Interconnection Point specified in

    Section 1.03 above, by 138,000 volt metering

    equipment to be installed, owned and maintained by

    Indianapolis Company; and

       4.022  At such other points as may be hereafter

    agreed upon, such equipment at each such other

    metering point to have such voltage rating and to be

    installed under such arrangement with respect to

    ownership and maintenance thereof as the parties

    mutually determine.

Metering

    4.03  Suitable metering equipment at the metering

points as provided in Section 4.02 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.

    4.04  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 4.02 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 hereto as

hereinabove provided, the other party hereto shall have

the right to install check metering equipment at the

aforesaid metering points.  Check 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 check 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.

    4.05  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 hereto, 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.

    4.06  If, at any test of metering equipment an

inaccuracy shall be disclosed exceeding two percent, the

account between the parties hereto for service

theretofore delivered shall be adjusted to correct for

the inaccuracy 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 4.03 hereof 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 5

                 RECORDS AND STATEMENTS

Records

    5.01  In addition to records of the metering

provided for in Article 4 hereof, the parties hereto

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

    5.02  As promptly as practicable after the end of

each calendar month, the parties hereto shall cause to be

prepared a statement setting forth the electric power and

energy transactions between them during such month in

such detail and with such segregations as may be needed

for operating records or for settlements under the

provision of this agreement.

                       ARTICLE 6

                 BILLINGS AND PAYMENTS

    6.01  All bills for amounts owed by one party hereto

to the other shall be due and payable on the fifteenth

day of the month next following the month 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.  The term "month" shall mean a calendar

month for the purpose of settlements under this

agreement.

                       ARTICLE 7

                   EMERGENCY SERVICE

              Under Agreement, dated as of
                December 2, 1968 between

         Indianapolis Power & Light Company and
       Southern Indiana Gas and Electric Company

SECTION 1 - DURATION

    1.1  This Service Schedule, a part of and under

agreement (referred to in this Schedule as the Agreement)

dated as of December 2, 1968, between Indianapolis Power

& Light Company (Indianapolis Company) and Southern

Indiana Gas and Electric Company (Southern Indiana

Company) shall become effective on the Interconnection

Date as defined in Section 9.01 of Article 9 of the

Agreement and shall continue in effect until termination

of the Agreement.

SECTION 2 - SERVICES TO BE RENDERED

    2.1  Subject to the provisions of subsection 2.2 of

this Section 2, in the event of a breakdown or other

emergency in or on the system of either party involving

either sources of power or transmission facilities, or

both, impairing or jeopardizing the ability of the party

suffering the emergency to meet the loads of its system,

the other party shall deliver to such party such electric

energy as it is requested to deliver; provided, however,

that neither party shall be obligated to deliver such

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 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 as provided for in subsection 2.1 of this

Section 2 is subject to two conditions which may preclude

the delivery of such energy as so provided:  (a) the

party requested to deliver electric energy may be

suffering an emergency in or on its own system as

described in said subsection 2.1, or (b) the system of

the party of whom such request is made may be delivering

electric energy, under a mutual emergency interchange

agreement, to the system of another interconnected

company which is suffering an emergency in or on its

system.  Under conditions as cited under (a) above,

neither party shall be considered to be in default

hereunder if unable to comply with the provisions of said

subsection 2.1.  Under conditions as cited under (b)

above, neither party shall be considered to be in default

hereunder if it is unable to comply with the provisions

of said subsection 2.1 provided that the aforesaid

interconnected company has suffered said emergency in or

on its system prior to and within forty-eight hours of

that of the other party hereto and that, if requested by

said other party, such delivery of electric energy to

said interconnected company shall be discontinued within

forty-eight hours following the start of such delivery,

and a subsequent delivery shall be made for a full forty-

eight hour period to said other party in accordance with

the provisions of said subsection 2.1.

    2.3  If at any time the record over a 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 the

Agreement.  It shall be the purpose of such study to

determine the adequacy or inadequacy of reserve

generating capacity and transmission facilities being

provided to meet the requirements of the parties'

respective systems, reflecting obligations under the

Agreement, and, if inadequate, the extent of the burden

that one party may be placing upon the other.  If it

should be found that one party is placing an unreasonable

burden upon the other, the party causing such burden

shall take such measures as are necessary to remove the

burden from the other party, or the parties shall enter

into such arrangements as shall provide for equitable

compensation to the party being burdened.

SECTION 3 - COMPENSATION

    3.1  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 in

Section 4.01 of Article 4 of the 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 percent of such cost.  If equivalent

energy is returned, it shall be returned at times when

the load conditions of the party receiving it are

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 B

                    ENERGY TRANSFER

              Under Agreement, dated as of

                December 2, 1968 between

         Indianapolis Power & Light Company and

       Southern Indiana Gas and Electric Company

SECTION 1 - DURATION

    1.1  This Service Schedule, a part of and under

agreement (referred to in this Schedule as the Agreement)

dated as of December 2, 1968, between Indianapolis Power

& Light Company (Indianapolis Company) and Southern

Indiana Gas and Electric Company (Southern Indiana

Company) shall become effective on the Interconnection

Date as defined in Section 9.01 of Article 9 of the

Agreement and shall continue in effect until termination

of the Agreement.

SECTION 2 - TRANSFER ARRANGEMENT

    2.1  In carrying out the interconnected operation of

their respective systems as provided for under the

Agreement, energy being received by a portion of one

party's system from another portion of its system or 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 agree as follows; viz.:

       2.11  Such energy transfer over their respective

    transmission 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 to meet its own requirements, as described

    under 2.11 above, is not affected adversely or

    jeopardized.  In the event the need for such

    additional transmission facilities becomes apparent

    to either of the parties during 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 5 of the Agreement.  Proper consideration to such

electrical losses will be in accordance with the manner

agreed upon by the Operating Committee.  It is understood

by the parties, however, that such electrical losses

resulting from energy 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.

                December 2, 1968 between

         Indianapolis Power & Light Company and
       Southern Indiana Gas and Electric Company

SECTION 1 - DURATION

    1.1  This Service Schedule, a part of and under

agreement (referred to in this Schedule as the Agreement)

dated as of December 2, 1968, between Indianapolis Power

& Light Company (Indianapolis Company) and Southern

Indiana Gas and Electric Company, Inc. (Southern Indiana

Company) shall become effective on the Interconnection

Date as defined in Section 9.01 of Article 9 of the

Agreement and shall continue in effect until termination

of the Agreement.

SECTION 2 - SERVICES TO BE RENDERED

    Economy Energy

    2.1  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.

    Compensation - Economy Energy

    2.2  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

    2.3  It is further recognized that from time to time

occasions will arise when the effecting of transactions

as provided in 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, 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.

    Compensation - Non-Displacement Energy

    2.4  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 4.01 of Article 4 of the 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 D

                    SHORT TERM POWER

              Under Agreement, dated as of
                December 2, 1968 between

         Indianapolis Power & Light Company and
       Southern Indiana Gas and Electric Company

SECTION 1 - DURATION

    1.1  This Service Schedule, a part of and under

agreement (referred to in this Schedule as the

Agreement), dated as of December 2, 1968, between

Indianapolis Power & Light Company (Indianapolis Company)

and Southern Indiana Gas and Electric Company (Southern

Indiana Company) shall become effective on the

Interconnection Date as defined in Section 9.01 of

Article 9 of the Agreement and shall continue in effect

until termination of the Agreement.

SECTION 2 - SERVICES TO BE RENDERED

    2.1  Either party by giving the other party notice

may reserve for periods of not less than one calendar

week if the reservation begins with Sunday or Monday or

for the balance of the calendar week if the reservation

begins with any day subsequent to Monday, 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 it 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 acknowledgement, shall signify the extent of

    its ability and willingness to comply with the

    provision of such notice.  Any notice or any

    acknowledgement 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,

    excluding a Saturday, Sunday and holidays, 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 4.01 of Article 4 of the

    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 shall have 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

    period shall be taken as equal to the number of

    kilowatts reserved for such period 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 or if the

    period is less than a week at the rate of $0.06 per

    kilowatt per day.  In the event the amount of Short

    Term Energy taken is reduced upon request of the

    supplying party, the demand charge for the period

    during which such 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 4.01 of

    Article 4 of the 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.

         Indianapolis Power & Light Company and
       Southern Indiana Gas and Electric Company

SECTION 1 - DURATION

    1.1  This Service Schedule, a part of and under

agreement (referred to in this Schedule as the

Agreement), dated as of December 2, 1968, between

Indianapolis Power & Light Company (Indianapolis Company)

and Southern Indiana Gas and Electric Company (Southern

Indiana Company) shall become effective on the

Interconnection Date as defined in Section 9.01 of

Article 9 of the Agreement and shall continue in effect

until termination of the Agreement.

SECTION 2 - SERVICES TO BE RENDERED

    2.1  In the 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, the parties shall arrange for, deliver, and take

electric power and energy in amounts and under conditions

as follows; viz.:

       2.11  Either party, to the extent that it has

    capacity available and is willing to do so, may

    supply to the other electric energy in an amount up

    to, but not limited to, 25,000 kilowatts to provide

    for and coordinate the scheduled maintenance,

    repair, and overhauling of generating facilities in

    the system of the other party.  The party desiring a

    supply of maintenance energy shall initiate the

    delivery and receipt thereof by informing the other

    party of such desire.  A schedule setting forth the

    intervals and extent of the use to be made of

    maintenance energy shall be agreed upon by both

    parties.  For the purposes of this Service Schedule

    the full twelve months period commencing with the

    January 1st after the effective date of this Service

    Schedule 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.  Maintenance energy shall be settled for by

    the return of maintenance energy equivalent to that

    supplied, except that if, at the end of a

    Maintenance Period there is a balance of maintenance

    energy owed by one party to the other, the party to

    whom such balance is owed may, at its option,

    require that the owing party pay 110% of the

    out-of-pocket cost to the supplying party of

    supplying such balance.  Such out-of-pocket cost

    computations shall be based on the assumption the

    kilowatt-hour balance being settled for consists of

    the kilowatt-hours most recently delivered to the

    owing party under this schedule.  Equivalent energy

    shall be energy returned at times when the load

    conditions of the party receiving it are

    substantially equivalent to the load conditions of

    such party at the time the electric energy for which

    it is returned was delivered or, if such party

    elects to have energy returned under different

    conditions, it shall be returned in such amounts to

    be agreed upon by the parties hereto, as will

    compensate for the difference in conditions.

       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 Southern Indiana Company

    and, conversely, the dates of such intervals during

    which Southern 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 quantities

    agreed upon 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 quantities

    agreed upon from the other under this Service

    Schedule.

       2.13  On the day next preceding the first day of

    an interval as described in 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 4.01 of the

    Agreement.

SECTION 3 - MODIFICATION

    3.1  Either party, by written notice given to the

other party not less than ninety days prior to the end of

the first or any subsequent Maintenance Period, may call

for a reconsideration of the terms and conditions of this

Service Schedule, provided that no subsequent

reconsideration shall be made earlier than one year

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 date of this Service

Schedule 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.

         December 2, 1968, as modified, between

         Indianapolis Power & Light Company and
       Southern Indiana Gas and Electric Company

SECTION 1 - DURATION

    1.1  This Service Schedule, a part of and under

agreement (referred to in this Schedule as the

Agreement), dated as of December 2, 1968, between

Indianapolis Power & Light Company (Indianapolis Company)

and Southern Indiana Gas and Electric Company (Southern

Indiana Company) shall become effective March 1, 1977 or

at such later date as is practicable under applicable

regulations or orders of the Federal Power Commission,

and shall continue in effect until termination 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 one or more calendar weeks or

for periods of less than one week, 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 it 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 acknowledgement, shall signify the extent of

    its ability and willingness to comply with the

    provisions of such notice.  Any notice or any

    acknowledgement 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,

    excluding a Saturday, Sunday and holidays, 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 set

    forth in Section 4.01 of Article 4 of the 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 shall have 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

    period shall be taken as equal to the number of

    kilowatts reserved for such period 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 $0.55 per kilowatt for such week or if the

    period is less than a calendar week, at the rate of

    $0.095 per kilowatt per day.  In the event the

    amount of Short Term Energy taken is reduced upon

    the request of the supplying party, the demand

    charge for the period during which such reduction is

    made shall be reduced $0.095 per kilowatt of

    reduction for each day during which any reduction is

    in effect.  However, such reduction shall not exceed

    $0.55 per kilowatt for a calendar week.

         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 set forth in Section 4.01 of Article

    4 of the 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.

              Under Agreement, dated as of

         December 2, 1968, as modified, between

         Indianapolis Power & Light Company and

       Southern Indiana Gas and Electric Company

SECTION 1 - DURATION

    1.1  This Service Schedule, a part of and under

agreement (referred to in this Schedule as the

Agreement), dated as of December 2, 1968, between

Indianapolis Power & Light Company (Indianapolis Company)

and Southern Indiana Gas and Electric Company (Southern

Indiana Company) shall become effective March 1, 1977 or

at such later date as is practicable under applicable

regulations or orders of the Federal Power Commission,

and shall continue in effect until termination of the

Agreement.

SECTION 2 - SERVICES TO BE RENDERED

    2.1  Either Party by giving the other party notice

may reserve for periods of not less than one month or

more than twelve months, such electric power (herein

called Limited Term Power (Firm)) as the other party may

be willing to make available as Limited Term Power

(Firm).  The party asked to supply Limited Term Power

(Firm) shall be the sole judge as to the amounts and

periods that it has electric power available that may be

reserved by the other party as Limited Term Power (Firm).

    2.11  To reserve Limited Term Power (Firm), 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.  The party receiving such notice shall

    signify the extent of its ability and willingness to

    comply with the provisions of such notice.  Any

    notice or any acknowledgement of such notice that

    initially may be given orally shall be confirmed

    thereafter in writing.

    2.12  During each period that Limited Term Power

    (Firm) has been reserved as above provided, the

    party having agreed to supply such power shall

    deliver upon call electric energy (herein called

    Limited Term Energy (Firm)) to the other party at

    the delivery point or points set forth in Section

    4.01 of Article 4 of the Agreement in any amount up

    to and including 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 Limited Term

    Energy (Firm) to be burdensome to the supplying

    party, the supplying party may reduce or interrupt

    the delivery of such energy to preserve the

    integrity of, or to prevent or limit any instability

    on, its system.

    2.13  The Limited Term Power (Firm) billing demand

    for any period shall be taken as equal to the number

    of kilowatts reserved as Limited Term Power (Firm)

    for such period.

SECTION 3 - COMPENSATION

    3.1  Payments for the supply of Limited Term Power

(Firm) and Limited Term Energy (Firm) shall be predicated

on the following rates:

    3.11  Demand Charge

       For any month that Limited Term Power (Firm) is

    reserved, $3.00 per kilowatt reserved.  However, in

    the event the Limited Term Power (Firm) reserved is

    reduced upon the request of the supplying party, the

    demand charge for the period during which such

    reduction is made shall be reduced $0.10 per

    kilowatt of reduction for each day during which any

    reduction is in effect.  However, such reduction

    shall not exceed $3.00 per kilowatt month.

    3.12  Energy Charge

       For the kilowatt-hours of Limited Term Power

    (Firm) taken, at a rate per kilowatt-hour equal to

    the out-of-pocket cost (such cost being as of the

    delivery point or points set forth in Section 4.01

    of Article 4 of the 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 percent of such

    cost.

              Under Agreement, dated as of
         December 2, 1968, as modified, between

         Indianapolis Power & Light Company and
       Southern Indiana Gas and Electric Company

SECTION 1 - DURATION

    1.1  This Service Schedule, a part of and under

agreement (referred to in this Schedule as the

Agreement), dated as of December 2, 1968, between

Indianapolis Power & Light Company (Indianapolis Company)

and Southern Indiana Gas and Electric Company (Southern

Indiana Company) shall become effective June 1, 1980 or

at such later date as is practicable under applicable

regulations or orders of the Federal Power Commission,

and shall continue in effect until termination 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 one or more calendar weeks or

for periods of less than one week, 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 it 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 acknowledgement, shall signify the extent of

    its ability and willingness to comply with the

    provisions of such notice.  Any notice or any

    acknowledgement 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,

    excluding a Saturday, Sunday, and holidays,

    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 set

    forth in Section 4.01 of Article 4 of the 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 shall have 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

    period shall be taken as equal to the number of

    kilowatts reserved for such period 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 calendar week

    at the rate of $0.85 per kilowatt for such week or

    if the period is less than a calendar week, at the

    rate of $0.14 per kilowatt per day.  In the event

    the amount of Short Term Energy taken is reduced

    upon the request of the supplying party, the demand

    charge for the period during which such reduction is

    made shall be reduced $0.14 per kilowatt of

    reduction for each day during which any reduction is

    in effect.  However, such reduction shall not exceed

    $0.85 per kilowatt for a calendar week.

         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 set forth in Section 4.01 of Article

    4 of the 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.

         Indianapolis Power & Light Company and

       Southern Indiana Gas and Electric Company

Indianapolis Power & Light Company (Indianapolis Company)

and Southern Indiana Gas and Electric Company (Southern

Indiana Company) shall become effective June 1, 1980 or

at such later date as is practicable under applicable

regulations or orders of the Federal Energy Regulatory

Commission, and shall continue in effect until

termination of the Agreement.

SECTION 2 - SERVICES TO BE RENDERED

    2.1  Either party by giving the other party notice

may reserve for periods of not less than one month or

more than twelve months, such electric power (herein

called Limited Term Power (Firm)) as the other party may

be willing to make available as Limited Term Power

(Firm).  The party asked to supply Limited Term Power

(Firm) shall be the sole judge as to the amounts and

periods that it has electric power available that may be

reserved by the other party as Limited Term Power (Firm).

    2.11  To reserve Limited Term Power (Firm), 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.  The party receiving such notice shall

    signify the extent of its ability and willingness to

    comply with the provisions of such notice.  Any

    notice or any acknowledgement of such notice that

    initially may be given orally shall be confirmed

    thereafter in writing.

    2.12  During each period that Limited Term Power

    (Firm) has been reserved as above provided, the

    party having agreed to supply such power shall

    deliver upon call electric energy (herein called

    Limited Term Energy (Firm)) to the other party at

    the delivery point or points set forth in Section

    4.01 of Article 4 of the Agreement in any amount up

    to and including 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 Limited Term

    Energy (Firm) to be burdensome to the supplying

    party, the supplying party may reduce or interrupt

    the delivery of such energy to preserve the

    integrity of, or to prevent or limit any instability

    on, its system.

    2.13  The Limited Term Power (Firm) billing demand

    for any period shall be taken as equal to the number

    of kilowatts reserved as Limited Term Power (Firm)

    for such period.

SECTION 3 - COMPENSATION

    3.1  Payments for the supply of Limited Term Power

(Firm) and Limited Term Energy (Firm) shall be predicated

on the following rates:

    3.11  Demand Charge

       For any month that Limited Term Power (Firm) is

    reserved, $4.50 per kilowatt reserved.  However, in

    the event the Limited Term Power (Firm) reserved is

    reduced upon the request of the supplying party, the

    demand charge for the period during which such

    reduction is made shall be reduced $0.15 per

    kilowatt of reduction for each day during which any

    reduction is in effect.  However, such reduction

    shall not exceed $4.50 per kilowatt month.

    3.12  Energy Charge

       For the kilowatt-hours of Limited Term Power

    (Firm) taken, at a rate per kilowatt-hour equal to

    the out-of-pocket cost (such cost being as of the

    delivery point or points set forth in Section 4.01

    of Article 4 of the 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 percent of such

    cost.

SECTION 2 - SERVICES TO BE RENDERED

    2.1  Either party by giving the other party notice

may reserve for periods of one or more days or weeks,

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 it has electric power available

that may be reserved by the other party as Short Term

Power.  As used herein, the term "week" shall mean any

seven consecutive days.

       2.11  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

    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 shall have the right

    to request that the other party reduce its take of

    such energy to the lesser amount specified 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

    period shall be taken as equal to the number of

       kilowatt).  For each period less than one week

       that Short Term Power is reserved, $0.18 per

       kilowatt reserved per day; less, for any day

       during any party of which the amount of Short

       Term Power is reduced by the supplying party,

       $0.18 per kilowatt of the reduction; plus

         3.12  110% of the out-of-pocket costs of

    supplying the Short Term Energy taken during such

    reservation periods that comes from the supplying

    party's own system; plus, for energy purchased by

    the supplying party from another system to supply

    any part of the Short Term Energy taken during such

    reservation periods, 100% of the amount paid

    therefor by the supplying party plus 10% thereof,

    but not to exceed (a) 1.6 mills per kilowatt-hour if

    Indianapolis Company is the supplying party, or (b)

    2.1 mills per kilowatt-hour if Southern Indiana

    Company is the supplying party.

                Under Agreement Between

           Indianapolis Power & Light Company

                          And

       Southern Indiana Gas and Electric Company

SECTION 1 - DURATION

    1.1  This Service Schedule, a part of and under

Agreement (herein called the "Agreement"), dated as of

December 2, 1968, between Indianapolis Power & Light

Company ("Indianapolis Company') and Southern Indiana Gas

and Electric Company ("Southern Indiana Company"), shall

become effective June 1, 1982 or at such later date as is

practicable under applicable regulations or orders of the

Federal Energy Regulatory Commission, and shall continue

in effect until termination of the Agreement.

SECTION 2 - SERVICES TO BE RENDERED

    2.1  Either party by giving the other party notice

may reserve for periods of not less than one month or

more than twelve months, such electric powers herein

called "Limited Term Power (Firm)", as the other party

may be willing to make available as Limited Term Power

(Firm).  The party asked to supply Limited Term Power

(Firm) shall be the sole judge as to the amounts and

periods that it will make electric power available for

reservation by the other party as Limited Term Power

(Firm).

    2.11  To reserve Limited Term Power (Firm), 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.  The party receiving such notice shall

    signify the extent of its ability and willingness to

    comply with the provisions of such notice.  Any

    notice or any acknowledgement of such notice that

    initially may be given orally shall be confirmed

    thereafter in writing.

    2.12  During each period that Limited Term Power

    (Firm) has been reserved as above provided, the

    party having agreed to supply such power shall

    deliver, upon call, electric energy, herein called

    "Limited Term Energy (Firm)", to the other party at

    the delivery point or points set forth in Section

    4.01 of Article 4 of the Agreement in any amount up

    to and including 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 Limited Term

    Energy (Firm) to be burdensome to the supplying

    party, the supplying party may reduce or interrupt

    the delivery of such energy to preserve the

    integrity of, or to prevent or limit any instability

    on, its system.

    2.13  The Limited Term Power (Firm) billing demand

    for any period shall be taken as equal to the number

    of kilowatts reserved as Limited Term Power (Firm)

    for such period.

SECTION 3 - COMPENSATION

    3.1  The reserving party shall pay the supplying

party:

    3.11  For any month that Limited Term Power (Firm)

    is reserved, $5.50 per kilowatt reserved.  However,

    in the event the Limited Term Power (Firm) reserved

    is reduced upon the request of the supplying party,

    the demand charge for the period during which such

    reduction is made shall be reduced $0.185 per

    kilowatt of reduction for each day during which any

    reduction is in effect.  However, such reduction

    shall not exceed $5.50 per kilowatt-month; plus

    3.12  110% of the out-of-pocket costs of supplying

    the Limited Term Energy (Firm) taken during such

    reservation periods that comes from the supplying

    party's own system; plus, for energy purchased by

    the supplying party from another system to supply

    any part of the Limited Term Energy (Firm) taken

    during such reservation periods, 100% of the amount

    paid therefor by the supplying party plus 10%

    thereof, but not to exceed (a) 1.6 mills per

    kilowatt-hour if Indianapolis Company is the

    supplying party, or (b) 2.1 mills per kilowatt-hour

    if Southern Indiana Company is the supplying party.

by revising Section 9.02 to read as follows:

       "9.02  Either party upon at least thirty months'
       prior written notice to the other, may terminate
       this agreement after the expiration of the
       initial term or any successive term hereof;
       provided, that this agreement shall not be deemed
       to have terminated until all prior commitments
       for the sale or purchase of power under this
       agreement have been fulfilled.

and by deleting Section 9.03 in its entirety.

    1.03  Article 18 is hereby added to the 1968
Agreement to read as follows:

                      "ARTICLE 18

                        "DEFAULT

             "18.01  Default Defined.  As used herein,

                   SERVICE SCHEDULE A

                   EMERGENCY SERVICE

SECTION 1 - DURATION

1.1  This Service Schedule, being a part of and under

Modification No. 8 to the Interconnection Agreement

(referred to herein as the "1968 Agreement") dated as of

December 2, 1968 between Indianapolis Power & Light

Company (hereinafter called "IPL" or a "Party") and

Southern Indiana Gas and Electric Company, Inc.

(hereinafter called "SIGECO" or a "Party") shall become

effective as of the date of the Eighth Modification and

shall continue in effective throughout the duration of

the 1968 Agreement.

SECTION 2 - SERVICES TO BE RENDERED

2.1  Conditional Service.  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 that it

is requested to deliver; provided, however, that neither

Party shall be obligated to deliver such 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 to the other for a period in excess of forty-eight

(48) consecutive hours during any single emergency.

    2.2  Non-Performance.  The Parties recognize that

the delivery of electric energy as provided in subsection

2.1 of this Section 2 is subject to two conditions which

may preclude the delivery of such energy as so provided:

(a) the Party requested to deliver electric energy may be

suffering an emergency in or on its own system as

described in said subsection 2.1, or (b) the system of 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 it is 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, however,

that such Party shall make every effort consistent with

the terms of its contract with said other interconnected

company to make the electric energy as provided in

subsection 2.1 available to the other Party hereto as

soon as possible.

    2.3  Reserve Generating Capacity Review.  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 the 1989 Agreement.  It shall be the purpose

of such study to determine the adequacy or inadequacy of

reserve generating capacity and transmission facilities

being provided to meet the requirements of the Parties'

respective systems, reflecting obligations under the

Agreement, and, if inadequate, the extent of the burden

that one Party may be placing upon the other.  If it

should be found that one Party is placing an unreasonable

burden upon the other, the Party causing such burden

shall take such measures as are necessary to remove the

burden from the other Party, or the Parties shall enter

into such arrangements as shall provide for equitable

compensation to the Party being burdened.

SECTION 3 - COMPENSATION

    3.1  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 in

Section 4.01 and 4.02 of Article 4 of the 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 generating such energy

plus ten percent of such cost.  If equivalent energy is

returned, it shall be returned at times when the load

conditions of the Party electing to receive 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.

3.2  Electric energy delivered under Section 2 above that

is purchased by the supplying Party's system from another

interconnected system shall be settled for by the payment

of 100% of the amount paid therefore by the supplying

Party plus the following:

    3.21  Where IPL is the supplying Party, up to 3.46

    mills per kilowatt-hour (2.46 mills/KWH for bulk

    transmission charges plus 1.0 mill/KWH for difficult

    to quantify energy related costs) plus the cost of

    any transmission losses, taxes, and other expenses

    incurred that would not have been incurred if such

    transaction had not been made.

    3.22  Where SIGECO is the supplying Party, up to

    3.19 mills per kilowatt-hour (2.19 mills/KWH for

    bulk transmission charge plus 1.0 mill/KWH for

    difficult to quantify energy-related costs) plus the

    cost of any transmission losses, taxes, and other

    expenses incurred that would not have been incurred

    if such transaction had not been made.

                                           Exhibit III

                   SERVICE SCHEDULE C

                   INTERCHANGE ENERGY

SECTION 1 - DURATION

1.1  This Service Schedule, a part of and under

Modification No. 8 to the Interconnection Agreement

(referred to herein as the "1968 Agreement") dated as of

December 2, 1968 between Indianapolis Power & Light

Company (hereinafter called "IPL" or a "Party") and

Southern Indiana Gas and Electric Company, Inc.

(hereinafter called "SIGECO" or a "Party") shall become

effective as of the date of the Eighth Modification and

shall continue in effective throughout the duration of

the 1968 Agreement.

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

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 in subsection 2.1 of this Section 2 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, 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 Party shall be based on the

principle that the Party purchasing it shall pay the

out-of-pocket cost (including all operating, maintenance,

tax, transmission losses and other expenses incurred that

would not have been incurred if the energy had not been

supplied) 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 the 1968 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 costs of the receiving Party

or system would have been to generate such energy, and

(2) the out-of-pocket costs of the supplying Party or

system providing the energy.  Such allocation shall be

made as provided in subsection 3.21 and 3.22 hereinbelow:

    3.21  The transmitting Party shall be paid (a) its

    cost of purchasing the Energy supplied, plus (b) its

    costs of additional transmission losses plus (c) the

    following:

        (1) When IPL is such transmitting Party:

            The greater of (i) fifteen percent of the

            gross savings remaining after deducting all

            such payments for transmission losses or

            (ii) an amount not to exceed 3.46 mills per

            kilowatt-hour of Energy received for

            transmission.

        (2) When SIGECO is such transmitting Party:

            The greater of (i) fifteen percent of the

            gross savings remaining after deducting all

            such payments for transmission losses or

            (ii) an amount not to exceed 3.19 mills per

            kilowatt-hour of Energy received for

            transmission.

    3.22  The supplying Party or system shall be paid

    its out-of-pocket cost 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.

3.3  Prior to any transaction involving the delivery and

receipt of Economy Energy, as provided in subsection 3.1

and 3.2 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

3.4  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 in Sections

SECTION 1 - DURATION

1.1  This Service Schedule, being a part of and under

Modification No. 8 to the Interconnection Agreement

(referred to herein as the "1968 Agreement") dated as of

December 2, 1968 between Indianapolis Power & Light

Company (hereinafter called "IPL" or a "Party") and

Southern Indiana Gas and Electric Company, Inc.

(hereinafter called "SIGECO" or a "Party") shall become

effective as of the date of the Eighth Modification and

shall continue in effect throughout the duration of the

1968 Agreement.

SECTION 2 - SERVICES TO BE RENDERED

2.1  Either Party by giving the other Party notice may

reserve from the other, (a) electric power ("Weekly Short

Term Power") for periods of one or more weeks or (b)

electric power ("Daily Short Term Power") for periods of

one or more days whenever, the Party requested to reserve

the same, is willing to make such power available.  Under

ordinary circumstances such reservation shall extend for

not less than a calendar week if it begins with Sunday or

for the balance of the calendar week if it begins with

any day subsequent to the Sunday; however, under unusual

circumstances, the Parties may mutually agree upon a

reservation of Daily or Weekly Short Term Power for a

lesser number of days.  In all cases the Party asked to

supply Daily or Weekly Short Term Power shall be the sole

judge as to the amounts and periods that it has electric

power available that may be reserved by the other Party

as Short Term Power.

        2.11  Prior to each reservation of Weekly or

    Daily Short Term Power, the number of kilowatts to

    be reserved, the period of the reservation, the

    terms of such reservation, and the source of such

    power if the supplying Party is in turn reserving

    such power from another interconnected system

    ("Third Party"), shall be determined by the Parties.

    Such determination shall be confirmed in writing at

    the request of either Party.  If during such period

    conditions arise that could not have been reasonably

    foreseen at the time of the reservation and cause

    the reservation to be burdensome to the supplying

    Party or its system, such Party may by oral notice

    to the reserving Party, such oral notice to be later

    confirmed in writing if requested by either Party,

    reduce the number of kilowatts reserved by such

    amount and for such time as it shall specify in such

    notice, but kilowatts reserved hereunder that the

    supplying Party is in turn reserving from another

    system may be reduced only to the extent they are

    reduced by such other system.

        2.12  During the period that Weekly or Daily

    Short Term Power has been reserved, the Party that

    has agreed to supply such power shall upon call by

    the reserving Party deliver associated electric

    energy ("Weekly or Daily Short Term Energy") to the

    reserving Party as of the delivery point or points,

    as provided in Section 4.01 and 4.02 of Article 4 of

    the 1968 Agreement at a rate during each hour of up

    to and including the number of kilowatts reserved.

Modification No. 8 does not accept it for filing within

ninety (90) days after its submission, or requires any

modification to its rates, terms, or conditions as a

condition of accepting Modification No. 8 for filing,

either Party may terminate Modification No. 8, if in such

Party's good faith judgment such modification materially

changes the benefits or burdens to the Party desiring to

terminate; provided, the terminating Party has used its

best efforts to obtain regulatory acceptance.  In that

event, such Party may terminate Modification No. 8 and

this Service Schedule G by notifying the other Party in

writing of its intention to so terminate not more than

         Service Schedule C         Interchange Energy

         Service Schedule D         Short Term Power and Energy

         Service Schedule F         Limited Term Power (Firm)

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
Energy, Short Term Power and Energy, and Limited Term
Power (Firm), 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.

            EMISSIONS CONSTRAINED DISPATCH PLAN
                 Effective January 1, 1995

Economic Dispatch is loading each generating unit so the lowest cost
generation is called upon first to generate the power needed, thereby
minimizing total electric energy generation cost.  Emissions Constrained
Dispatch is simply Economic Dispatch where the estimated value of the
SO2 allowances being consumed by a unit is included as a part of the
unit's cost of generation.  A lower emitting unit will reflect a
relatively lower emissions cost because it requires fewer sulfur dioxide
(SO2) allowances.

IPL's plan to implement Emissions Constrained Dispatch is to incorporate
SO2 allowance values into the existing Energy Management System (load
dispatching system), which economically dispatches IPL's generation.  As
the generation required (load) increases, the available unit with the
lowest incremental cost is dispatched to meet the increase.  As the
generation demanded decreases, the unit with the highest incremental cost
is dispatched to reduce its generation, thereby minimizing cost.1

Currently, the Energy Management System uses incremental heat
rates, along with fuel and variable operation costs to
determine the incremental cost of generation on each unit in
service.  Effective January 1, 1995, SO2 emissions related
costs will be included in each unit's incremental cost prior
to the incremental costs being compared to make the unit
dispatch.

The incremental SO2 value will be in units of dollars per million British
Thermal Units ($/MMBTU) and computed by the following guidelines:

        IPL plans to use EPA (Environmental Protection Agency)
        certifiable data for SO2 emission rates in conjunction with
        the incremental value of emission allowances to form the
        emissions dispatch cost in units of $/MMBTU.  Each
        generating unit affected by the Clean Air Act will have its
        own specific SO2 emissions data input into the Energy
        Management System at the beginning of each month. That data
        will remain for the month unless projected coal deliveries
        for the month have an SO2 value that will change the current
        dispatch.  The Fuel Supply Organization will notify the System
        Operation Office of the projected coal delivery SO2 emission
        rate in #SO2/MMBTU, so that a correct SO2 emission rate can
        be input into the Energy Management System.

        1  Optimization of unit loadings in the Energy
Management System is constrained by equipment physical
limitations such as maximum rate of load pickup or maximum
load reduction rate on a unit as well as contrained by the
maximum and minimum capability of the units.

        IPL's Treasury Organization will not less often than the 10th day
        of each month supply the IPL System Operation Office the incremental
        value of an emission allowance in units of dollars per ton of SO2
        based upon the Cantor Fitzgerald asking price for allowances, or
        other nationally recognized allowance trading market price, for use
        in IPL's emission constrained dispatch on a forward going basis.
        Beginning January 1, 1995, the allowance price that will be used for
        purposes of IPL's emissions constrained dispatch will be the asking
        price for allowances obtained from Cantor Fitzgerald on December 30,
        1994.  The Treasury Organization will track the emission allowance
        market and if a significant change in allowance prices occurs within
        a given month, the Treasury Organization may provide an updated
        allowance price value to the IPL System Operation Office.  The
        updated allowance price will be entered into the Energy Management
        System and the economic dispatch algorithm will be updated
        accordingly.

The emissions cost will be added with the fuel and variable
operating cost to produce a total dispatch cost.  The total
dispatch cost will be combined with the incremental unit heat
rate data to produce the total incremental dispatch cost as
calculated by the following formula:

        INCREMENTAL COST = (Fuel Cost + Emissions Value Divided By
                                Variable Operating Cost) X Incremental
                                Heat Rate

The dimensions for each of the variables is as follows:

        Emissions Value, $/MMBTU; Fuel Cost, $/MMBTU; Variable Operating
        Cost $/MMBTU; Incremental Heat Rate, MMBTU/MWH; Allowance Value,
        $/Allowance; Incremental Cost, $/MWH

The dispatch made using the total incremental cost, including
SO2 emissions related costs, will constitute IPL's Emissions
Constrained Dispatch.

plus "one mill per kilowatt-hour for difficult to quantify energy
related costs."  Service Schedule C is hereby be revised to
remove the term "one mill per kilowatt-hour for difficult to
quantify energy related costs."

3)   Transmission and ancillary services necessary to effectuate
sales under the Interconnection Agreement shall be arranged by
IPL under and subject to the rates, terms, and conditions of
IPL's Open Access Transmission Tariff.  The rates for point-to-
point transmission service and the two ancillary services
necessary to effectuate sales under the Interconnection Agreement
are provided below.  IPL will provide either Short-Term Firm
Point-to-Point or Non-Firm Point-to-Point transmission service
and ancillary services for Scheduling, System Control and
Dispatch Service (Scheduling Service), and Reactive Supply and
Voltage Control from Generation Sources Service (Reactive Supply

Agreement, and there will be no charge for such services in
connection with the sales under the Interconnection Agreement.

     The rates for both Short-Term Firm and Non-Firm Point-to-
Point Service are:  $ 930.00/MW of reserved capacity for monthly
service, $215.00/MW of reserved capacity for weekly service,
$43.00/MW of reserved capacity for on-peak daily, and $30.70/MW
of reserved capacity for off-peak daily service with the daily
service capacity charges capped at the weekly rates.  Non-Firm
Point-to-Point service is available on an hourly basis at
$2.69/MW for on-peak hours and $1.28/MWH for off-peak hours with
the maximum hourly charges capped at the daily rates.

     For Scheduling Service, the monthly charges are $10.00/MW of
reservation, the weekly rate is $3.00/MW, the daily rate is
$0.60/MW, and the hourly rate is $0.04/MWH.  The sum of the
hourly charges is capped at the daily rates, the sum of the daily
charges is capped at the weekly rate, and the sum of the weekly
charges is capped at the monthly rate.

     For Reactive Supply Service, the monthly charges are
$110.00/MW of reservation, the weekly rate is $25.00/MW, the
daily rate is $5.00/MW, and the hourly rate is $0.31/MWH.  The
sum of the hourly charges is capped at the daily rates, the sum
of the daily charges is capped at the weekly rate, and the sum of
the weekly charges is capped at the monthly rate.

     If transmission and ancillary services are obtained by
Southern Indiana Gas & Electric Company under Indianapolis Power
& Light Company's Open Access Transmission Tariff, there will be
no charge related to transmission and ancillary service assessed
under the Interconnection Agreement.  A service agreement under
Indianapolis Power & Light Company's Open Access Transmission
Tariff is on file as of the effective date of this Modification
No. 10 to govern service to Southern Indiana Gas & Electric
