in consideration of the premises and of the mutual covenants herein set forth,
the Parties hereto agree as follows:

 

 

ARTICLE 1

PROVISIONS FOR, AND CONTINUITY OF INTERCONNECTED OPERATION

Interconnection Points.

The respective 69,000 volt,138,000 volt and 345,000 volt transmission systems of
IPL and PSI are presently interconnected at the following points:
 i.   The 138kv Five Points Interconnection Point
 ii.  The 345kv Whitestown Interconnection Point
 iii. The 345kv Gwynneville Interconnection Point
 iv.  The 138kv Petersburg Interconnection Point
 v.   The 345kv Petersburg Interconnection Point
 vi.  The 138kv Centerton Interconnection Point
 vii. The 138kv Carmel Tap Point

(viii) The 345kv Frances Creek Interconnection Point

Future Interconnection Points.
The services provided for by the 2002 Agreement may also be rendered through
such other points of interconnection as the Parties may later agree upon by
amending the 2002 Agreement.
Synchronous Operation.
The Parties mutually agree that, except as provided in Service Schedule D
hereof, their respective systems will be continuously operated in parallel
(except in cases of interruption of such parallel operation due to mutually
agreed upon maintenance or due to causes beyond the control of either Party, or
due to the necessity of an interruption of parallel operation in order that the
native load served by either Party may continue to receive adequate service from
such Party). If synchronous operation of the systems through a particular line
or lines become interrupted either manually or automatically because of any of
the above- stated reasons, the Parties shall cooperate so as to remove the cause
of such interruption as soon as practicable and restore such line or lines to
normal operating conditions.

1.03.1. Inadvertent Flow.

It is recognized that in interconnected system operation, power and reactive
flow will exist on an interconnection due to scheduled power flow from either
Party to third parties or between third parties. This inadvertent power flow
depends mainly on the design of the internal systems of the Parties and the
interconnected system, and the schedules of power flows on the interconnections.

Interruption of Operations.
If, in the sole judgment of either Party, the power or reactive flow over the
interconnection facilities of either Party is excessive to the extent that it
jeopardizes the reliability of either Party's service to its customers, the
Parties shall attempt to agree upon adequate corrective measures to eliminate or
control such excessive power or reactive flow; provided, however, that in the
event such a situation exists, the Party so burdened shall have the right, with
notice when possible to the other Party, to open and leave open one or all of
the interconnections between the respective systems of the Parties until
corrective action has been taken. The Parties further aggress to study and
negotiate the installation, ownership, and cost of any additional equipment
necessary to effect a long-term solution to any such excessive loading as herein
described in the event either Party determines that this interconnection
contributes to the excessive loading and requests such negotiation.

Maintenance of Equipment
. Each of the Parties shall keep, or shall cause to be kept, the transmission
lines together with all associated equipment and appurtenances that are located
on their respective sides of the Interconnection Points specified in Section
1.01 hereof, or agreed upon pursuant to Section 1.02 hereof, in a suitable
condition of repair at all times, each at its own expense, in order that said
transmission lines will operate in a reliable and satisfactory manner and in
order that reduction in the effective capacity of said transmission lines will
be avoided to the extent practicable.

 

ARTICLE 2

SERVICES TO BE RENDERED

Interconnection Services Schedules.
It is the purpose of the Parties to seek and realize, on an equitable basis, all
benefits which may be practicably effected through coordination in the operation
and development of their respective systems. It is understood by the Parties
that such benefits may be realized by each of them by carrying out under stated
terms and conditions various interconnection services and transactions that may
from time to time include among others:

 i.   The furnishing of emergency service,
 ii.  The interchange, sale, and purchase of energy to effect operating
      economies,
 iii. The sale and purchase of short term electric power and energy available on
      the system of one Party and needed on the system of the other, and
 iv.  The transmission of power and energy on the basis of simultaneous
      transfers.

In furtherance of such purpose, the Parties shall create, and continue the
functioning of, an Operating Committee, as provided in Article 7 hereof.

Specific Terms and Conditions.
Since the specific services to be rendered in furtherance of such purpose will
vary during the term of the 2002 Agreement, and the terms and conditions
applicable to such services may require modification from time to time, it is
intended that such specific services and the terms and conditions applicable
thereto will be set forth in Service Schedules mutually agreed upon between the
Parties. Such Service Schedules, unless and until changed, terminated, or
supplemented, shall be those specified in Section 2.03 hereof. If a Service
Schedule under the 2002 Agreement is changed or supplemented, such Service
Schedule shall be fully restated in order to reflect such change or supplement.
Service Schedules.
The respective Service Schedules designated

Service Schedule A - Emergency Service

Service Schedule B - Interchange Energy

Service Schedule C - Short Term Power and Energy

Service Schedule D - Carmel Southeast Tap Network Power & Energy

Transfer

have been agreed upon between the Parties, are identified as Exhibits I, II,
III, and IV, respectively, to the 2002 Agreement and are attached hereto and
made a part hereof the same as if incorporated herein. It is contemplated by the
Parties that all additional mutually agreed upon Service Schedules will be made
a part of the 2002 Agreement upon presentation and acceptance thereof.

2.04. Out-Of-Pocket Costs

. The term "Out-of-Pocket Cost" of energy from generating units on the system of
a Party shall consist of any costs that are directly incurred by IPL or PSI by
reason of its generation of such energy and which otherwise would not have been
incurred by such system including, but not limited to, fuel, labor, operation,
maintenance, start- up, fuel handling, taxes, regulatory commission charges, and
emission allowances.

"Out-of-Pocket Cost" of energy purchased from a third party by the supplying
Party shall consist of the total amount paid therefore by the supplying Party
which otherwise would not have been paid by such Party, plus any cost which
otherwise would not have been incurred, including, but no limited to, regulatory
commission charges, emission allowances, transmission losses and taxes related
to such transaction.

Tax expenses will be the expenses that are incurred as taxes either in
connection with the sale or production of such energy

2.05

. Emission Allowances. The federal Clean Air Act, as amended, 42 U.S.C. 7401 et
seq. (hereinafter referred to as "Clean Air Act"), establishes certain annual
maximum sulfur dioxide ("SO2") levels, stated in terms of required emission
allowances, for flue gases emitted by electric generating units, including units
operated by IPL, PSI and other electric utilities who may supply electric energy
for transactions under the 2002 Agreement. The generator of the electric energy
supplied and delivered under the 2002 Agreement is required by the Clean Air Act
to have adequate "allowances" (as defined by Section 402 (3) of the Clean Air
Act in conjunction with Section 403 (f) of the Clean Air Act) in order to
generate such electric energy. To the extent that either IPL or PSI are required
by the Clean Air Act to have additional allowances by reason of its generation
of electric energy to be supplied by it under the 2002 Agreement, which
allowances would otherwise not have been required by such supplying by it under
the 2002 Agreement, which allowances would otherwise not have been required by
such supplying Party, then, unless the supplying Party otherwise agrees in
advance in writing, at the discretion of the supplying Party, the Party
receiving such energy shall be responsible for the cost or the actual furnishing
(without cost to the supplying Party) of adequate allowances to the supplying
Party in order for such Party to supply such energy under the Agreement. The
Parties shall establish, by mutual agreement, appropriate procedures in order to
carry out the provisions of this Section 2.05, including a statement of costs
before any transactions under the Service Schedules attached hereto are started.
Also, prior to implementation of every transaction under the Service Schedules
attached hereto, the purchasing Party must declare whether they will pay in cash
or return SO2 Allowances in-kind for any consumption of SO2 Allowances directly
attribute to such transaction, if any.

It shall be the responsibility of the supplying Party to provide the receiving
Party, before the transaction begins, with a statement of the estimated emission
allowance charges associated with the transaction which the supplying Party is
seeking to add to the rates to be charged under the applicable Service Schedule.
Failure of the supplying Party to provide a statement of such charges before the
transaction begins shall constitute a waiver of the recovery of any such costs.
In establishing such procedures, the Parties shall recognize that the
determination of the additional allowances required in order to generate the
electric energy to be supplied hereunder is subject to variables contingent upon
the loading and operating conditions on the system where the actual generation
occurs. The procedures so established by the Parties shall be in accord with
sound engineering principles of power plant and system operation, and shall
require the furnishing of such additional allowances at such times and in such
amounts as will be equitable to the supplying Party.

When IPL is the supplier of energy and emission allowances, the recovery of the
applicable costs for the actual furnishing of adequate allowances in order for
IPL to generate and supply such energy will be implemented in the following
manner:

 1. 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, as determined in
    Subsection 2 (b) of this Section 2.05, 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 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 Allowance 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 2002 Agreement, 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

 2. Determination of SO2 Emission Allowances Due IPL
     a. 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 Allowance
        per MWH for each unit, will be used to determine the number of SO2
        Allowances attributable to the sale.
    
     b. 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.

When PSI is the supplier of energy and emission allowances, the recovery of the
applicable costs for the actual furnishing of adequate allowances in order for
PSI to generate and supply such energy will be implemented in the following
manner:

 1. The current Environmental Protection Agency ("EPA") auction price to value
    emission allowances will be used for energy sales transactions. The dispatch
    criteria may be revised from time to time if the emission allowance
    purchases on the average are determined to be significantly different than
    the EPA auction price.
 2. For each hour in which there is a transaction for energy services using an
    Out-of-Pocket Cost rate under the 2002 Agreement, PSI will:
     a. identify the generation sources used to provide the transaction's energy
        by identifying the energy that would not have been used had the
        transaction not been in effect that hour by using the same
        after-the-fact incrementing costing model that is used to calculate the
        incremental cost of fuel under the 2002 Agreement;
    
         
    
     b. determine, using the following formula, the quantity of emission
        allowances related to the energy transaction: (i) by calculating an
        incremental heat rate for the appropriate generating unit and the
        corresponding incremental SO2 emission levels, as determined by the
        computer based tools, for the identified units dispatched to serve the
        transaction; (ii) applying the following formula for such unit; (iii)
        adding together the total number of tons of SO2 produced per million BTU
        (i.e., British Thermal Unit) of fuel burned by each such unit for the
        transaction; and (iv) letting one (1) emission allowance equal one (1)
        ton of SO2 so produced.

    # OF UNITS

    S (MBTU sale - MBTU no sales) * (SO2) * (100%-SE)

    100%

    MBTU sale = Million BTU consumed on unit n with sale.

    MBTU no sale = Million BTU consumed on unit n without sale.

    SO2 = Tons of SO2 produced per million BTU of fuel burned.

    SE = Scrubber Efficiency in %

    PSI will perform periodic tests to maintain the accuracy and validity of
    such emission rate information. Because some generating sources may not be
    subject to Clean Air Act during Phase I or Phase II thereunder, there will
    be no emission allowance charges included for the utilization of such an
    energy source while it is not subject to such requirements. One (1) emission
    allowance shall be assigned to each ton of SO2 emitted to serve the
    transaction. Fractions of emission allowance tons will be rounded up to the
    next whole number when the fraction is equal to or greater than .5 and
    rounded down when the fraction is less than .5.

 3. The purchasing Party of energy shall have the option of purchasing or
    providing emission allowance for each transaction. The purchasing Party
    shall notify PSI of its election to purchase or provide emission allowances
    prior to the start of the transaction. The running quantity of emission
    allowances charged or furnished will be shown on the monthly invoices to the
    purchasing Party.
 4. When the purchasing Party of energy elects to purchase the emission
    allowances from PSI, then the quantity of emission allowances used will be
    included as part of the charges on the monthly invoices to the purchasing
    Party.
 5. By January 15th of the year following the calendar year in which the
    transaction occurred, the purchasing Party of energy shall transfer the
    appropriate emission allowances to PSI for the emission allowances used when
    the allowances are provided in kind.
 6. PSI has adopted the same incremental cost calculation to value emission
    allowances for dispatch criteria as for billing energy transactions.

 

ARTICLE 3

SERVICE CONDITIONS

Control of System Disturbance.
Each Party shall maintain and operate its system so as to minimize, in
accordance with sound operating practice , the likelihood of disturbance
originating in either Party's 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.
It is the intent that neither Party shall be obligated to deliver kilovars for
the benefit of the other Party; also that neither Party shall be obligated to
receive kilovars when to do so may introduce objectionable operating conditions
on its system. The Operating Committee shall be responsible for the
establishment of operating procedures and schedules in respect of carrying
kilovar loads by one Party's systems for the other Party's system in order to
secure adequate service and economical use of facilities of both Party's 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 Party, 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 the systems of both Parties. The operating procedures
and schedules so established by the Operating Committee shall be in accord with
such principles and shall require each Party to carry kilovar loads at such
times and in such amounts as will be equitable to both Parties.

Control of Unscheduled Power Deliveries.
The Parties shall exercise due diligence and foresight in carrying out all
matters related to the providing and operating of their respective electric
power resources so as to minimize to the extent practicable deviations between
actual and scheduled deliveries of electric power and energy between their
systems. The Parties shall provide and install on their respective systems such
communication and telemetering facilities as are essential to so minimize such
deviations and, in developing and executing operating procedures that will
enable the Parties to avoid to the extent practicable deviation from scheduled
deliveries, shall fully cooperate with each other and with third parties whose
systems are either directly or indirectly interconnected with the systems of the
Parties and who of necessity, together with the Parties must unify their efforts
cooperatively to achieve effective and efficient interconnected operation. The
Parties recognize, however, that, despite their best efforts to prevent the
same, unscheduled deliveries of electric energy from one Party to the other may
occur. In such event, electric energy delivered hereunder shall be settled for
by the return of equivalent energy. Equivalent energy 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.
All electric energy delivered under the 2002 Agreement shall be of the character
commonly know as three-phase sixty Hertz energy, and shall be delivered at the
Interconnection Points specified under Section 1.01 hereof, at a nominal voltage
of 138,000 volts at the Five Points and Centerton Interconnection Points, at the
138KV Petersburg Interconnection Point, and at the Carmel Tap Point; and at a
nominal voltage of 345,000 volts at the Whitestown and Gwynneville
Interconnection Points, at the 345KV Petersburg Interconnection Point, and at
the Frances Creek Interconnection Point; and at such other points and voltages
as hereafter may be agreed upon by the Parties pursuant to Section 1.02 hereof.
In addition to the interconnection points provided in Sections 1.01 and 1.02,
PSI may request IPL deliver electric energy under the 2002 Agreement at
interconnection points IPL may have with third parties (hereinafter referred to
as "Alternate Delivery Points").
Billing Based on Scheduled Transactions.
As IPL and PSI systems are interconnected with other systems forming a network,
it is recognized that, because of the physical and electrical characteristics of
the facilities involved, a part or all of the energy being transferred from one
Party to the other may flow through such other systems rather than through the
point or points of connection between the systems of the Parties. A part or all
of the power being transferred between other systems in the network may flow
through the point or points of connection between the systems of the Parties,
and as a result be included in the demand and energy meter readings at the point
or points of interconnection. Therefore, all billings shall be based on
scheduled transactions or upon methods determined by the Operating Committee
which may result from development of arrangements with other interconnected
systems and which provide a basis for accounting for the power and energy
transfers actually contracted for between the Parties.
Metering Points.
Electric power and energy supplied and delivered under the 2002 Agreement shall
be measured by suitable metering equipment which shall be provided, owned and
maintained by PSI or IPL as designated below at the following metering points:

 i.  138,000 volt metering equipment installed by PSI at the Five Points
     Substation; 138,000 volt metering equipment installed by PSI at the
     Centerton Substation; 138,000 and 345,000 volt metering equipment installed
     by IPL at the Petersburg Station; 345,000 volt metering equipment install
     by IPL at its Sunnyside Substation and at PSI's Gwynneville and Whitestown
     Substations; 12.47kv metering equipment installed by PSI at its Carmel
     Southeast Substation; and 345,000 volt metering equipment installed by PSI
     at its Frances Creek Substation, and
 ii. At such other locations as hereafter may be agreed upon by the Parties
     pursuant to Section 1.02 hereof.

 

Electric power and energy supplied and delivered at the Alternate Delivery
Points specified in Section 4.01 shall be measured by metering equipment either
provided, owned and maintained by IPL or third parties. Such metering equipment
shall not be subject to Sections 4.04 through 4.07 but shall meet the reasonable
requirements of the Operating Committee.

Metering Equipment.
Suitable metering equipment at the metering points as described in Section 4.03
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: (i) an automatic record of the kilowatt-hours for
each clock-hour, and (ii) a continuous integration record of the kilowatt-hours.
Measurement of Electric Energy.
Measurements of electric energy for the purpose of effecting settlements under
the 2002 Agreement shall be made by standard types of electric meters installed
and maintained (unless otherwise provided for in the Agreement) by the owner at
the metering points described in Section 4.03 above. The timing devices of all
meters having such devices shall be maintained in the synchronism as closely as
practicable.

The meters shall be sealed and the seals shall be broken only upon occasions
when the meters are to be tested or adjusted. For the purpose of checking the
records of the metering equipment installed by one of the Parties as hereinabove
provided, the other Party shall have the right to install check metering
equipment at the aforesaid metering points. Metering equipment so installed by
one Party on the premises of the other Party, unless otherwise provided for in
the 2002 Agreement, shall be owned and maintained by the Party installing such
equipment. Upon termination of the 2002 Agreement, the Party owning such
metering equipment shall remove it from the premises of the other Party.
Authorized representatives of both Parties shall have access at all reasonable
hours to the premises where the meters are located and to the records made by
the meters.

Testing and Access to Meters and Records.
The aforesaid metering equipment shall be tested by the owner at suitable
intervals and its accuracy of registration maintained in accordance with good
practice. On request of either Party, a special test may be made at the expense
of the Party requesting such special test. Representatives of both Parties shall
be afforded the 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.
Adjustments Due to Inaccuracies.
If at any test of metering equipment an inaccuracy shall be disclosed exceeding
two percent, the account between the Parties for service theretofore delivered
shall be adjusted to correct for the inaccuracy disclosed over the shorter of
the following two periods: (i) for the thirty (30) day period immediately
preceding the day of the test, or (ii) for the period that such inaccuracy may
be determined to have existed. Should the metering equipment described in
Section 4.04 above at any time fail to register, the electric power and energy
delivered shall be determined from the check meters, if installed, or otherwise
shall be determined from the best available data.

 

ARTICLE 5

RECORDS AND STATEMENTS

5.01. Records. In addition to records of the metering provided for in Article 4
hereof, the Parties shall keep in duplicate such other records as may be needed
to afford a clear history of the various deliveries of electric energy made by
one Party to the other and of the clock-hour integrated demands in
kilowatt-hours delivered by one Party to the other. In maintaining such records,
the Parties shall effect such segregations and allocations of demands and
electric energy delivered into classes representing the various

services and conditions as may be needed in connection with settlements under
the 2002 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 that the Parties may agree upon a different time interval
for such delivery.

Statements.
As promptly as practicable after the end of each calendar month, the Parties
shall prepare a statement setting forth the electric power and energy
transactions between the Parties during such month in such detail and with such
segregations as may be needed for operating records or for settlements under the
provisions of the 2002 Agreement.

 

ARTICLE 6

BILLINGS AND PAYMENTS

Billing Period.
Unless otherwise agreed upon by the Parties, the calendar month shall be the
standard billing period for all settlements under the
2002
Agreement.
Billing scheduled Transactions.
All billing shall be based on scheduled transactions unless otherwise determined
as provided in Section 4.02 hereof.
Billing Payments.
All bills for amounts owed by one Party to the other Party shall be due on the
first business day following the fifteenth (15
th
) day after the end of the calendar month or period service was rendered, or on
the tenth (10
th
) business day following receipt of a bill, whichever is later. Payments shall
be made by electronic transfer or by such other mutually agreeable method as
shall cause such payment to be available for the account of the payee on or
before the due date. Interest on unpaid amounts, both principal and interest,
shall accrue daily at the then current prime interest rate per annum of The
Chase Manhattan Bank, N.A., New York, New York, plus two percent (2%) per annum,
or the maximum rate permitted by law, whichever is less, from the date due until
the date upon which payment is made.

Estimated Billing Factors.
In order that bills may be rendered promptly after the end of each month, it may
be necessary, from time to time, to estimate certain factors involved in
calculating the monthly billing. Adjustments for errors in such estimates shall
be included in the bill for the month following the time when information
becomes available to make such corrections or adjustments in the billing for the
preceding month or moths.
Billing Disputes.
If a Party disputes the correctness of a bill, such Party will, nevertheless,
pay the undisputed portion of such bill, plus a minimum of one-half (1/2) of the
disputed amount, and shall submit to the other Party a written statement
detailing the items disputed. If the Parties are unable to agree upon the
disputed items, such items shall be submitted to the Operating Committee for
further action consistent with the 2002 Agreement.

 

 

ARTICLE 7

OPERATING COMMITTEE

 1. Operating Committee Organization and Duties

. To coordinate the operation of their respective generation, transmission and
substation facilities in order that the benefits of the 2002 Agreement may be
realized by the Parties to the fullest practicable extent, the Parties shall
establish a committee of authorized representatives to be known as the Operating
Committee. Each of the Parties shall designate in writing delivered to the other
Party, the person who is to act as its authorized representative (the "OC
Representative") on said committee (and the person or persons who may serve as
Alternate whenever the OC Representative is unable to act). The OC
Representative and Alternate or Alternates shall each be persons familiar with
the generation, transmission, and substation facilities of the system of the
Party he represents, and each shall be fully authorized (i) to cooperate with
the other OC Representative (or Alternates) and (ii) as the need arises and
subject to the declared intentions of the Parties as herein set forth and to the
terms hereof and the terms of any other agreements then in effect between the
Parties, to determine and agree from time to time upon the following:
 i.   All matters pertaining to the coordination of maintenance of the
      generation and transmission facilities of the Parties.
 ii.  All matters pertaining to the control of time, frequency, energy flow,
      kilovar exchange, power factor, voltage, and other similar matters bearing
      upon the satisfactory synchronous operation of the systems of the Parties.
 iii. Such other matters not specifically provided for herein upon which
      cooperation, coordination and agreement as to quantity, time, method,
      terms and conditions are necessary, in order that the operation of the
      respective systems of the Parties may be coordinated to the end that the
      potential benefits anticipated by the Parties will be realized to the

ARTICLE 8

CONTINUITY AND SUSPENSION OF SERVICE

RELATIVE RESPONSIBILITIES AND LIABILITY LIMITS

 1. Continuity and Suspension of Service

. Each Party shall exercise reasonable care and foresight to maintain continuity
of service as provided in the 2002 Agreement. In no event shall one Party be
liable to the other Party or its customers for loss or damage arising from
failure to provide or for the interruption or suspension of any service provided
for herein. Each Party reserves the right to suspend service without liability
at such time and for such periods and in such manner as it deems advisable,
including, without limitation, suspensions for the purpose of making necessary
adjustments to, changes in, or repairs on, its facilities and to suspend service
in cases where, in its sole opinion, the continuance of service to the other
Party would endanger persons or property. Both Parties shall use their best
efforts to provide each other with reasonable notice in the event of suspension
of service. Relative Responsibilities. Each Party assumes all responsibility for
receipt and delivery of electricity on its system to and from the Points of
Interconnection specified in Section 1.01 hereof or agreed upon pursuant to
Section 1.02 hereof or as requested by PSI pursuant to Section 4.01. Neither
Party assumes any responsibility with respect to the construction, installation,
maintenance or operation of the system of the other Party or of the systems of
third parties, in whole or in part. In no event shall one Party be liable to the
other Party for damage or injury to any person or property, whatsoever, arising,
accruing or resulting from, in any manner, the receiving, transmission, control,
use, application or distribution of said electric power and energy. Each Party
shall use reasonable diligence to maintain its facilities in proper and
serviceable condition, and shall take reasonable steps and precautions for
maintaining the services agreed to be provided and received under the 2002
Agreement. Each Party shall be responsible for its own compliance with all
applicable environmental regulations and shall bear all costs arising from its
failure to comply with such environmental regulations. Limitation of Liability.
In no event shall one Party be liable to the other Party for any indirect,
special, incidental or consequential damages with respect to any claim arising
out of the 2002 Agreement.

giving notice to the other Party of its intention to terminate the 2002
Agreement at lease two (2) years prior to the end of the Initial Term or any

termination hereunder shall be given to the President or Chief Operations
Officer of a Party with a copy to the OC Representative of such Party.

 

ARTICLE 10

WAIVERS

Any waiver at any time by either Party of their rights with respect to a default
under the 2002 Agreement, or with respect to any other matter arising in
connection with the 2002 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 the 2002 Agreement shall
not be deemed a waiver of such right.

 

ARTICLE 11

TAXES

If at any time during the term hereof there should be levied or assessed against
either Party any direct tax by any taxing authority on the capacity or energy
(or both) generated, purchased, sold, transmitted, interchanged or exchanged by
it, which tax is in addition to or different from the forms of such direct tax
as are being levied or assessed as of the date hereof and such direct tax
results in increasing the cost of either or both the Parties in carrying out the
provisions of the 2002 Agreement, then such increase shall be reflected in the
charges for capacity or energy (or both) furnished by one Party to the other
hereunder as is necessary in order to make adequate and equitable allowances for
such tax.

herein, and shall be treated as duly delivered when the same is either (a)
personally delivered to the President or Chief Operations Officer of the other
Party or (b) deposited in the United States mail, postage prepaid and properly

provided, however, that either Party may alter its recipient for notice
hereunder by written notice to the other Party in accordance with the provisions

ARTICLE 13

REGULATORY AUTHORITIES

 1. Regulatory Authority

. The 2002 Agreement is made subject to the authority of the Federal Energy
Regulatory Commission or any other governmental regulatory agency having
jurisdiction in the premises and, if any of the terms and conditions hereof are
altered or made impossible of performance by order, rule, or regulation of any
such regulatory agency, and the Parties hereto are unable to agree upon a
modification of such terms and conditions that will satisfy such order, rule, or
regulation, then neither Party shall be liable to the other for failure
thereafter to comply with such terms and conditions; provided, that if either
Party deems that the failure of such performance results in a substantial breach
of the 2002 Agreement, then the 2002 Agreement may be terminated forthwith upon
thirty (30) days' advance written notice.

Amendments. The 2002 Agreement and the annexed Service Schedules may be amended
by mutual agreement of the Parties, which amendment shall be in writing and
shall become effective in accordance with Section 13.01 hereof. The rates and
charges set forth in the annexed Service Schedules are subject to amendment and
change, and each Party reserves the right from time to time to seek
unilaterally, from any regulatory agency having jurisdiction, amendments or
changes in its rates and charges set forth therein in accordance with the
applicable law. Nothing contained in the 2002 Agreement, any annexed Service
Schedule or any supplements thereto shall be construed as affecting in any way
the right of either Party unilaterally to make application to the Federal Energy
Regulatory Commission (or any successor regulatory agency having jurisdiction)
for a change in rates under Section 205 of the Federal Power Act and pursuant to
the Commission's Rules and Regulation promulgated thereunder (or under
comparable statutes and regulations of a successor regulatory agency having
jurisdiction).

. Notwithstanding any provision of the 2002 Agreement to the contrary, the
Parties do not intend to create hereby any joint venture, partnership,
association taxable as a corporation, or other entity for the conduct of any
business for profit, and any construction of the 2002 Agreement to the contrary
which has an adverse tax effect on either Party shall render the 2002 Agreement
null and void from its inception. Computation of Time. In computing any period
of time prescribed or allowed by the 2002 Agreement, the day of the act, event,
or default from which the designated period of time begins to run shall be

Saturday, Sunday, or legal holiday, in which event the period shall run until
the end of the next business day which is not a Saturday, Sunday, or legal
holiday. Section Headings Not to Affect Meaning. The descriptive headings of the

inserted for convenience only and shall not modify or restrict any of the terms
and provisions thereof.

 

ARTICLE 15

ASSIGNMENT

The 2002 Agreement shall insure to the benefit of, and be binding upon, the

the services hereunder.

 

ARTICLE 16

ENTIRE AGREEMENT CONTAINED HEREIN

The 2002 Agreement contains the entire agreement between the Parties in respect
of the subject mater hereof, and there are no other understanding or agreements
between the Parties in respect thereof; provided, however, that nothing

whatsoever any rights or claims either Party may have against the other Party
pursuant to any other agreement in effect before the effective date of the 2002
Agreement with respect to any matter, including any right or claim to payments
after the effective date of the 2002 Agreement pursuant to other preexisting
agreement.
