the earliest Rate Class Effective Date hereunder the Certifying Company's
Tangible Net Worth is below the Minimum Tangible Net Worth and the Certifying
Company's investment rating is below the Minimum Investment Rating, then DLC, in

market-based POLR program for large C&I customers, then the POLR Supplier shall
cooperate in good faith with DLC and use all commercially reasonable efforts to
attempt to negotiate and execute any amendments to this Agreement that would be

Supplier may provide certain or all of such Ancillary Services) and that DLC's
costs attributable to such Ancillary Services (except for energy imbalance) at
the rates then set forth in Schedule 9B of the OATT shall be netted against
Billed Generation Revenues, as provided under the terms of this Agreement. The
POLR Supplier further acknowledges and agrees that any POLR Energy Imbalance

attributable to such EGS's load, (y) the FERC has issued an order, in a form
reasonably acceptable to the Parties, approving the terms and conditions of this
Agreement, and (z) the PUC has issued an order approving the Revised POLR I

2000, the POLR Supplier (as defined in the POLR I Agreement) shall no longer be
responsible for providing all Energy necessary to compensate for transmission
and distribution losses in the DLC Control Area other than those losses that are
the responsibility of others, but rather shall be responsible for providing all
Energy necessary to compensate for all transmission and distribution losses in
the DLC Control area that would be attributable to the POLR Supplier (as defined
in the POLR I Agreement) under the Supplier Tariff if the POLR Supplier were an
EGS, (iii) as of one minute after 11:59 p.m. (eastern time) on December 31,
2000, the POLR Supply Amount (as defined in the POLR I Agreement) shall be
modified such that the POLR Supplier (as defined in the POLR I Agreement) shall
no longer be responsible for all residual losses in the DLC Control Area, but
rather for only such POLR Supplier's pro rata allocation of the Residual Losses
and Unaccounted For Energy based on the amount of retail Energy consumed during
each hour (including average losses) attributable to Energy supplied pursuant to
the POLR I Agreement. In addition, as soon as practicable following the date
hereof, the POLR Supplier shall cause to be executed one or more amendments to
the POLR I Agreement providing that DLC retail customers classified in the AL

Supplier (as defined in the POLR I Agreement), on a daily basis, the payment for
GRA billed under the Revised Retail Tariff, if any, received by DLC as of the
close of business on the immediately preceding day, and (iii) DLC shall
reasonably cooperate with the efforts by the POLR Supplier, if warranted by
available evidence, to seek enforcement of the provisions relating to the
Switching Rule and the GRA under the Revised POLR I Retail Tariff, provided,
however, that in any such case the POLR Supplier shall reimburse DLC for its
reasonable costs (including attorney and consulting fees) incurred to obtain
regulatory relief or enforcement on behalf of the POLR Supplier.

                    (iii) Provided that conditions (w), (x) and (z) of
subsection (i) of this Section 4.1(h) are satisfied, the POLR Supplier shall (i)
consent, pursuant to the terms of the POLR I Agreement, to such modifications to

period of time after December 31, 2001 and (ii) shall, prior to January 1, 2002,
terminate that certain EGS Power Sales Agreement, dated as of April 28, 2000, by

     provision of Energy as the POLR Supplier shall reasonably request and DLC
     shall reasonably approve, including the name and logo of the POLR Supplier,
     and such other information upon which the Parties shall mutually agree.

               (f)  Retail Services.  DLC, or its designated agent or
                    ---------------
     contractor, shall continue to perform, at no cost to the POLR Supplier, all
     retail functions and services associated with DLC's retail customers, and
     all functions and services associated with Company Use Energy supplied
     under this Agreement, including, as applicable, distribution, metering,
     billing, customer collections, and universal service programs, in
     accordance with Good Utility Practice.

               (g)  Transmission and Distribution Outages.  As long as DLC is
                    -------------------------------------
     maintaining and operating the DLC Transmission System and DLC's
     distribution system in accordance with Good Utility Practice, DLC shall not
     be responsible to the POLR Supplier for (i) any lost revenues associated
     with the interruption by DLC of POLR load due to outages on the DLC
     Transmission System or DLC's distribution system or actions taken by DLC to
     protect the security and integrity of the DLC Transmission System or DLC's
     distribution system, nor (ii) any costs associated with the interruption by
     DLC of POLR load due to failures on the DLC Transmission System or DLC's
     distribution system or actions taken by DLC to protect the security and
     integrity of the DLC Transmission System or DLC's distribution system. In
     addition, DLC shall reasonably cooperate with the POLR Supplier to
     coordinate planned outages on the DLC Transmission System or DLC's
     distribution system to coincide as much as practicable with planned outages
     at the generating facilities located in the DLC Control Area and acquired
     by the POLR Supplier in the Asset Sale.

               (h)  Information.
                    -----------

                    (i)  Upon such notice from the POLR Supplier as is
          sufficient to permit DLC to compile the requested information,
          DLC shall provide the POLR Supplier such information regarding
          DLC's retail customers as the POLR Supplier shall reasonably
          request, including customer account numbers, names, addresses,
          phone numbers, rate classes and historical usage information,
          provided that (x) the POLR Supplier agrees to reimburse DLC for
          the incremental costs incurred in compiling and providing such
          information and (y) the release of such information does not
          conflict with any Law or agreement by which DLC is bound,
          including those respecting the privacy of, or confidentiality of
          information regarding, DLC's retail customers.

                    (ii) DLC shall use its good faith best efforts to
          cooperate with the POLR Supplier in exchanging information
          regarding or relating to the Parties' obligations hereunder.

          (iii)     The POLR Supplier shall have the right to audit the books
          and records of DLC to confirm the accuracy of the Billed Generation
          Revenues and the Net Billed Generation Revenues, provided that any
          such audit shall be at the POLR Supplier's expense, consistent with
          standard business practices and following reasonable notice to DLC.

               (i)  Ancillary Services.  DLC shall be responsible for securing
                    ------------------
and providing all Ancillary Services associated with DLC's retail customers
classified in a Rate Class for which the Transition Period has terminated and
Company Use Energy (provided that by separate, mutual agreement between the POLR
Supplier and DLC, the POLR Supplier may provide certain or all of such Ancillary
Services) and shall net DLC's costs attributable to such Ancillary Services
(except for energy imbalance) at the rates then set forth in Schedule 9B to the
OATT against Billed Generation Revenue, as provided under the terms of this
Agreement. If at any time DLC's costs for regulation and frequency response,
operating reserve -- spinning reserve and operating reserve -- supplemental
reserve ancillary services change, DLC shall file with the FERC an amendment to
Schedule 9B to the OATT to reflect any such change. At the expiration of the FE
Ancillary Services Agreement, DLC agrees to use commercially reasonable efforts
to provide a means by which the POLR Supplier can provide the Ancillary Services
requirements associated with its POLR obligations under this Agreement such that
the amounts deducted from Billed Generation Revenue are equal to the amounts
paid to the POLR Supplier pursuant to the POLR Supplier Ancillary Services
Agreement, but only in the event that doing so can be accomplished without
causing DLC to under-recover the Ancillary Services costs that it incurs on
behalf of retail customers being served under this Agreement.

               (j)  Regulatory Cooperation.  DLC agrees to reasonably cooperate
                    ----------------------
with efforts by the POLR Supplier, if warranted by available evidence, to seek
(i) regulatory relief from unfair practices by residential customers who elect
to receive Energy from an EGS at certain times of the year and who return to
POLR service at other times of the year, and (ii) enforcement of the provisions
relating to the Switching Rule and GRA contained in that certain Joint Petition
for Settlement filed with the PUC in Docket No. R-00974104 on November 29, 2000;
provided, however, that in any such case, the POLR Supplier shall reimburse DLC
for its reasonable costs (including attorney and consulting fees) incurred to
obtain regulatory relief or enforcement on behalf of the POLR Supplier. In
addition, DLC agrees to refrain from filing with the PUC any request for
modification of the Generation Rates, unless the Parties shall mutually agree
otherwise.

               (k)  POLR I Agreement Amendment.
                    --------------------------

                    (i)  Provided that (w) the PUC has issued an order approving
the Retail Tariff set forth on Schedule 2 attached hereto (unless the failure to
approve such Retail Tariff is based solely on the absence of a definitive
effective date for such Retail Tariff) and the Generation Rates set forth on
Schedule 3 attached hereto, (x) the PUC has issued an order approving
modifications to the Supplier Tariff such that each EGS is responsible for its
pro rata allocation of the Residual Losses and Unaccounted For Energy based on
the amount of retail Energy consumed during each hour (including average losses)
attributable to such EGS's load, (y) the FERC has issued an order, in form
reasonably acceptable to the Parties, approving the terms and conditions of this
Agreement, and (z) the PUC has issued an order approving the Revised POLR I
Retail Tariff, DLC shall execute, no later than February 15, 2001, one or more
amendments to the POLR I Agreement providing that (i) as of one minute after
11:59 p.m. (eastern time) on December 31, 2001, Company Use Energy shall no
longer be provided pursuant to the POLR I Agreement but instead shall be

minute after 11:59 p.m. (eastern time) on December 31, 2000, the POLR Supplier
(as defined in the POLR I Agreement) shall no longer be responsible for
providing all Energy necessary to compensate for transmission and distribution
losses in the DLC Control Area other than those losses that are the
responsibility of others, but rather shall be responsible for providing all
Energy necessary to compensate for all transmission and distribution losses in
the DLC Control area that would be attributable to the POLR Supplier (as defined
in the POLR I Agreement) under the Supplier Tariff if the POLR Supplier were an
EGS, (iii) as of one minute after 11:59 p.m. (eastern time) on December 31,
2000, the POLR Supply Amount (as defined in the POLR I Agreement) shall be
modified such that the POLR Supplier (as defined in the POLR I Agreement) shall
no longer be responsible for all residual losses in the DLC Control Area, but
rather for only such POLR Supplier's pro rata allocation of the Residual Losses
and Unaccounted For Energy based on the amount of retail Energy consumed during
each hour (including average losses) attributable to Energy supplied pursuant to
the POLR I Agreement. In addition, as soon as practicable following the date
hereof, DLC shall execute one or more amendments to the POLR I Agreement
providing that DLC retail customers classified in the AL and SH Rate Classes
shall continue to be served under the POLR I Agreement at the rates provided
therein through December 31, 2001.

                    (ii) Provided that conditions (w), (x) and (z) of subsection
(i) of this Section 4.2(k) are satisfied, as soon as practicable following the
date on which the PUC issues an order approving the Revised POLR I Retail
Tariff, DLC

                                       26
<PAGE>

shall execute one or more amendments to the POLR I Agreement and the Retail
Tariff (as defined in the POLR I Agreement) providing that (i) the Revised POLR
I Retail Tariff shall apply to the POLR I Agreement, (ii) GRA shall be
specifically excluded from the definition of Billed Generation Revenue (as
defined in the POLR I Agreement) and DLC shall pay to the POLR Supplier (as
defined in the POLR I Agreement), on a daily basis, the payment for GRA billed
under the Revised POLR I Retail Tariff, if any, received by DLC as of the close
of business on the immediately preceding day, and (iii) DLC shall reasonably
cooperate with the efforts by the POLR Supplier, if warranted by available
evidence, to seek enforcement of the provisions relating to the Switching Rule
and the GRA under the Revised POLR I Retail Tariff, provided, however, that in
any such case the POLR Supplier shall reimburse DLC for its reasonable costs
(including attorney and consulting fees) incurred to obtain regulatory relief or
enforcement on behalf of the POLR Supplier.

                         (iii) Provided that conditions (w), (x) and (z) of
subsection (i) of this Section 4.2(k) are satisfied, DLC shall cause to be made,
pursuant to the terms of the POLR I Agreement, such modifications to the Special
Contracts (as defined in the POLR I Agreement) as shall be necessary to
effectuate the terms set forth on Schedule 6 attached hereto.

                    (l)  Pilot Program.  If the PUC determines, pursuant to
                         -------------
Section III.B.8 of that certain Joint Petition for Settlement filed with the PUC
in Docket No. R-00974104 on November 29, 2000, to consider the institution of a
market-based POLR program for large C&I customers, then DLC shall cooperate in
good faith with the POLR Supplier and use all commercially reasonable efforts to
attempt to negotiate and execute any amendments to this Agreement that would be
necessary to implement a Pilot Program; provided, however, that, for the
avoidance of doubt, if such negotiations are not successful, the POLR Supplier
shall have no obligations under this Agreement to provide Energy for the Pilot
Program. In addition, DLC shall make a neutral filing with the PUC, on or before
December 31, 2002, evaluating the wholesale market in the DLC Control Area. DLC
agrees that any retail service adder billed to DLC's retail customers under a
Pilot Program shall be collected by DLC and shared between DLC and the POLR
Supplier as follows: DLC shall retain eighty percent (80%) of any such adder and
DLC shall pay to the POLR Supplier twenty percent (20%) of any such adder.

                    (m)  Maintenance.  DLC shall maintain and operate the DLC

                    (n)  Power Sales Agreement.  As soon as practicable
                         ---------------------
following the date hereof, DLC shall execute an amendment to the Power Sales
Agreement that deletes therefrom the second sentence of Section 2.1 of the Power
Sales Agreement.

               1.15 POLR Energy Imbalance and Supply Violations Charges.  For
                    ---------------------------------------------------
any hour during which there is POLR Energy Imbalance, the POLR Supplier shall
pay to DLC, in accordance with the billing procedures set forth in Article VII
of this Agreement, the following amounts, as applicable:

                    (a)  POLR Supplier Self-Schedules the POLR Supply Amount.
                         ---------------------------------------------------
In the event that the POLR Supplier does not either schedule the POLR Supply
Amount according to the POLR Supply Forecast, as contemplated by Section 4.3(b)
hereof, or Dynamically Schedule the POLR Supply Amount, as contemplated by
Section 4.3(c) hereof, then:

                         (i)   If the POLR Supplier delivers, in any hour, an
amount of Energy that is between 90% and 110% of the POLR Supply Amount for that
hour, the POLR Supplier shall, in the event of an under-delivery, pay to DLC an
amount of dollars equal to the charge under the OATT applicable to an under-
delivery of an amount of Energy equal to the POLR Energy Imbalance, and, in the
event of an over-delivery, receive a credit from DLC in an amount of dollars
equal to the credit under the OATT applicable to an over-delivery of an amount
of Energy equal to the POLR Energy Imbalance (net of any costs DLC incurs in
disposing of such excess Energy).

                         (ii)  If the POLR Supplier delivers, in any hour, an
amount of Energy that is at least 75% but less than 90% of the POLR Supply
Amount for that hour, the POLR Supplier shall pay to DLC an amount of dollars
equal to 110% of the charge under the OATT applicable to an under-delivery of an
amount of Energy equal to the POLR Energy Imbalance. If the POLR Supplier
delivers, in any hour, an amount of Energy that is less than 75% of the POLR
Supply Amount for that hour, the POLR Supplier shall pay to DLC an amount of
dollars equal to 125% of the charge under the OATT applicable to an under-
delivery of an amount of Energy equal to the POLR Energy Imbalance.

                         (iii) If the POLR Supplier delivers, in any hour, an
amount of Energy that is greater than 110% of the POLR Supply Amount for that
hour, the POLR Supplier shall receive from DLC a credit in an amount of dollars
equal to the credit under the OATT applicable to an over-delivery of an amount
of

                                       28
<PAGE>

Energy equal to that portion of the POLR Energy Imbalance attributable to the
portion of such over-delivery that does not exceed 110% of such POLR Supply
Amount (net of any costs DLC incurs in disposing of such excess Energy) as
contemplated by Section 4.3(a) hereof and, for the balance of such POLR Energy
Imbalance, attributable to the portion of such over-delivery that exceeds 110%
of such POLR Supply Amount, reimburse DLC for any costs it incurs in disposing
of such excess Energy.

                         (iv) If the POLR Supplier's failure to deliver the POLR
Supply Amount in accordance with Section 4.1 hereof causes DLC to Shed Load
during any hour, the POLR Supplier shall pay to DLC, in addition to any amounts
due under Sections 4.3 (a) - (c) hereunder, $1,000 per megawatt-hour of Shed
Load attributable to such failure plus any out-of-pocket costs incurred by DLC
as the result of claims, penalties, repairs, expenses or other damages resulting
from such Shed Load; provided, however, that if during any such hour (x) the
POLR Supplier delivers the full output of all of its operable generation (e.g.,
all generation that is not on forced outage and/or forced curtailments) to the
DLC Control Area (and delivers to DLC a certificate executed by a duly
authorized officer of the POLR Supplier to such effect) and nevertheless fails
to deliver the POLR Supply Amount and (y) DLC is unable to procure alternative
sources of Energy in the market sufficient to compensate for the POLR Supplier's
under-delivery, then the POLR Supplier shall pay to DLC, in addition to any
amounts due under Sections 4.3(a) - (c) hereunder, but in lieu of the $1,000 per
megawatt-hour of Shed Load described above, $100 per megawatt-hour of Shed Load
attributable to such failure plus any of the aforementioned out-of-pocket costs
incurred by DLC. For purposes of this Section 4.3(a)(iv), DLC shall determine
the amount of such Shed Load using Good Utility Practice.

               (b)  POLR Supplier Schedules the POLR Supply Amount According to
                    -----------------------------------------------------------
the POLR Supply Forecast.  In the event that the POLR Supplier schedules to the
------------------------
DLC Control Area, in any hour, an amount of Energy that is between 98% and 102%
of the amount of Energy forecast by DLC for such hour in the POLR Supply
Forecast for such hour last delivered by DLC to the POLR Supplier pursuant to
Section 5.1(a) hereof, the provisions of Section 4.3(a) and (c) hereof shall not
apply and in such an instance, if the POLR Supplier fails to deliver to the DLC
Control Area the POLR Supply Amount in accordance with Section 4.1 hereof for
such hour, the POLR Supplier shall, in the event of an under-delivery, pay to
DLC an amount of dollars equal to the charge under the OATT applicable to an
under-delivery of an amount of Energy equal to the POLR Energy Imbalance and, in
the event of an over-delivery, receive a credit from DLC in an amount of dollars
equal to the credit under the OATT applicable to an over-delivery of an amount
of Energy equal to the POLR Energy Imbalance (net of any costs DLC incurs in
disposing of such Energy).

               (c)  POLR Supplier Dynamically Schedules the POLR Supply Amount.
                    ----------------------------------------------------------
In the event that the POLR Supplier Dynamically Schedules the POLR Supply Amount
to the DLC Control Area, subject to the terms of Section 4.2(c) hereof, in any
hour, the provisions of Section 4.3(a) and (b) hereof shall not apply and in
such an instance, if the POLR Supplier fails to deliver to the DLC Control Area
the POLR Supply Amount in accordance with Section 4.1 hereof for such hour, the
POLR Supplier shall, in the event of an under-delivery, pay to DLC an amount of
dollars equal to the charge under the OATT applicable to an under-delivery of an
amount of Energy equal to the POLR Energy Imbalance and, in the event of an
over-delivery, receive a credit from DLC in an amount of dollars equal to the
credit under the OATT applicable to an over-delivery of an amount of Energy
equal to the POLR Energy Imbalance (net of any costs DLC incurs in disposing of
such Energy).

               (d)  Effect of Force Majeure and DLC T&D Outages.  The Parties
                    -------------------------------------------
agree that in the event that the POLR Supplier's failure to deliver the POLR
Supply Amount in accordance with Section 4.1 hereof resulted from (x) an event
of Force Majeure (and provided that the POLR Supplier complied with the
provisions of Article VIII hereof relating to events of Force Majeure) or (y)
outages on the DLC Transmission System or DLC's distribution system, the
provisions of Section 4.3(a) through (c) hereof shall not apply and in such an
instance, the POLR Supplier shall, in the event of an under-delivery, pay to DLC
an amount of dollars equal to the charge under the OATT applicable to an under-
delivery of an amount of Energy equal to the POLR Energy Imbalance and, in the
event of an over-delivery,

                                       30
<PAGE>

receive a credit from DLC in an amount of dollars equal to the credit under the
OATT applicable to an over-delivery of an amount of Energy equal to the POLR
Energy Imbalance (net of any costs DLC incurs in disposing of such Energy).

               (e)  Liquidated Damages.  The Parties agree that the foregoing
                    ------------------
payment provisions are an integral part of this Agreement and form a portion of
the consideration for the execution of this Agreement. The Parties recognize and
agree that the amounts set forth in this Section 4.3 represent a reasonable
estimate of the damages that would be incurred by DLC in the event the POLR
Supplier in any hour fails to deliver the POLR Supply Amount in accordance with
Section 4.1 hereof. The Parties further recognize and agree that the payment of
such amounts by the POLR Supplier is an appropriate remedy in the event of such
a failure and that any such payment does not constitute a forfeiture or penalty
of any kind but rather constitutes liquidated damages under the terms of this
Agreement.

          1.16 Demonstration of Ability to Perform.  Each April 1 and
               -----------------------------------
September 1 during the term of this Agreement, the POLR Supplier shall
demonstrate to DLC's reasonable satisfaction that the POLR Supplier has the
ability to perform its obligations under this Agreement during the following
calendar year. Such demonstration shall include a list of all resources,
including generation assets owned or operated by the POLR Supplier and Energy
purchase contracts, from which the POLR Supplier intends to obtain the Energy
necessary to satisfy its obligations under this Agreement, and shall provide
reasonable assurance that such resources satisfy any reserve margin or other
requirements then required by any Governmental Authority or applicable regional
or national reliability council, including NERC or ECAR, whether or not the POLR
Supplier is a member thereof. On or before the 15th day of each month during the
term of this Agreement, the POLR Supplier shall provide DLC with notice of any
significant changes in the POLR Supplier's list of resources described in the
preceding sentence.

(or such shorter period of time in the event of emergency operations as
contemplated by the Supplier Tariff).

               (b)  In addition, DLC shall deliver to the POLR Supplier, as
often as is practicable but in no event later than the end of each month, a
report listing known changes in the POLR Supply Amount, as well as any known
changes to the Schedules attached hereto, which changes shall be incorporated
into and become a part of the Schedules to which they relate, subject, however,
to the prior consent of the POLR Supplier to such changes to such Schedules if
such consent is required under this Agreement.

          1.19 Supply Scheduling.  The terms and conditions of Article 7 --
               -----------------

                     PAYMENT, INVOICING, ESCROW and OFFSET

          1.23 Daily Payment of Net Billed Generation Revenues; Monthly Payment
               ----------------------------------------------------------------
of the Company Use Energy Payment; and Daily Payment of the GRA Payment.
-----------------------------------------------------------------------
(a) Except as may otherwise be provided in this Article VII, beginning on the
thirty-fifth day following the earliest Rate Class Effective Date hereunder and
continuing until the end of the term of this Agreement (or the earlier
termination of this Agreement), DLC shall pay to the POLR Supplier the dollar
amount equal to the aggregate amount of the sum of the Net Billed Generation
Revenue attributable to each of DLC's retail customers that was billed by DLC,
and whose Energy requirements were included in the POLR Supply Amount, on the
date that was thirty-five (35) days prior to such day, whether or not such
billed amounts have been paid by such retail customers or EGSs. The Parties
recognize and agree that in calculating such Net Billed Generation Revenue, DLC
shall, as necessary, pro rate by kilowatt-hour usage the total amount of Net
Billed Generation Revenue attributable to such customers during such billing
period in order to account for that portion of such billing period during which
the POLR Supplier (as defined in the POLR I Agreement) supplied a portion of
such customer's Energy requirements and that portion of such billing period
during which the POLR Supplier supplied the POLR Supply Amount. DLC shall bill
all DLC retail customers on a current basis.

               (b)  Beginning on March 15, 2002 and continuing on the fifteenth
day of each calendar month thereafter until the end of the term of this
Agreement (or the earlier termination of this Agreement), DLC shall cause its
designated marketing affiliate pay to the POLR Supplier the Company Use Energy
Payment calculated for the Company Use Energy that was included in the POLR
Supply Amount during the calendar month ending on or about forty-five (45) days
prior to such date.

               (c)  Beginning on the earliest Rate Class Effective Date
hereunder and continuing on a daily basis until the end of the term of this
Agreement (or the earlier termination of this Agreement), DLC shall pay to the

business on the immediately preceding day.

          1.24 Monthly Invoicing for Preliminary Supplier Charges.  DLC shall,
               --------------------------------------------------
within ten (10) days following the end of each calendar month, invoice the POLR
Supplier for all Preliminary Supplier Charges attributable to such month.
Invoices rendered pursuant to this Section 7.2 shall be immediately due from the
POLR Supplier and payable to DLC by offset pursuant to Section 7.5 hereof.
Credits owing to the POLR Supplier reflected on any invoices rendered pursuant
to this Section 7.2 shall be immediately due from DLC and netted against any
payments owing to DLC on such invoice with any excess amount payable to the POLR
Supplier by increasing by the amount of any such excess the amount of Net Billed
Generation Revenue to be paid to the POLR Supplier under Section 7.1 hereof on
the day that the invoice reflecting such excess is rendered.

          1.25 Monthly Statement of Account for Supplier Charges (True-up and
               --------------------------------------------------------------
Adjustments).  DLC shall, after all customer accounts have been fully metered
------------
for a calendar month (which shall occur approximately forty-five (45) days
following the end of such calendar month), provide a statement of account to the
POLR Supplier adjusting one or more prior months' invoices rendered pursuant to
Section 7.2 hereof for the difference between Preliminary Supplier Charges and
Supplier Charges for such prior months.  Payments owing to DLC reflected on such
statements of account rendered pursuant to this Section 7.3 shall be immediately
due from the POLR Supplier and payable to DLC by offset pursuant to Section 7.5
hereof.  Credits owing to the POLR Supplier reflected on any statement of
account rendered pursuant to this Section 7.3 shall be immediately due from DLC
and netted against any payments owing to DLC on such statement of account with
any excess amount payable to the POLR Supplier by increasing by the amount of
any such excess the amount of Net Billed Generation Revenue to be paid to the
POLR Supplier under Section 7.1 hereof on the day that the statement of account
reflecting such excess is rendered.

          1.26 DLC Right to Escrow.  In addition to any other right to escrow
               -------------------
funds under this Agreement, DLC shall have the right to withhold payment of Net
Billed Generation Revenues otherwise owing to the POLR Supplier pursuant to
Section 7.1 hereof and to place such funds into an escrow account (the "Escrow
Account") subject to the terms and conditions of an escrow agreement
substantially in the form of that certain escrow agreement attached to the POLR
I Agreement (the "Escrow Agreement"), in the amounts and under the circumstances
provided below:

                                       35
<PAGE>

               (a)  Each Monday, DLC shall estimate the total Net Billed
Generation Revenue that was billed by DLC to DLC's retail customers within the
preceding seven (7) days. The amount so estimated is defined as the "Weekly NBGR
Estimate."

               (b)  Each Monday, DLC shall estimate that portion of the
Preliminary Supplier Charges that would be invoiced to the POLR Supplier under
Section 7.2 hereof and is attributable to the preceding (7) days. The amount so
estimated is defined as the "Weekly Supplier Charge Estimate."

               (c)  Each Monday, DLC shall sum all Weekly NBGR Estimates made
during the current calendar month (including the Weekly NBGR Estimate made that
day). The sum so calculated is defined as the "Cumulative Weekly NBGR Estimate."

               (d)  Each Monday, DLC shall sum all Weekly Supplier Charge
Estimates made during the current calendar month (including the Weekly Supplier
Charge Estimate made that day together with any known adjustments included in
any statement of account prepared by DLC pursuant to Section 7.3 hereof). The
sum so calculated is defined as the "Cumulative Weekly Supplier Charge
Estimate."

               (e)  On any Monday of a calendar month, if the Cumulative Weekly
Supplier Charge Estimate calculated pursuant to Section 7.4 (d) is greater than
the Cumulative Weekly NBGR Estimate calculated pursuant to Section 7.4 (c),
then, except as may otherwise be provided in Section 7.5 hereof, DLC may direct
payment to the Escrow Account of the Net Billed Generation Revenue that would
otherwise be payable to the POLR Supplier pursuant to Section 7.1 hereof, until
the earlier of the end of that calendar month or the next Monday in that
calendar month.

               (f)  If DLC is unable to escrow any amount of funds pursuant to
     Section 7.4 (e) because the funds are also subject to offset pursuant to
     Section 7.5 hereof (the "Escrow Shortfall"), then DLC may extend the period
     for escrow under Section 7.4 (e) until the dollar amount of the Escrow
     Shortfall has been withheld from payment of Net Billed Generation Revenues
     otherwise owing to the POLR Supplier pursuant to Section 7.1 hereof and
     placed into the Escrow Account.

          1.27 DLC Right to Offset.  In addition to any other right to offset
               -------------------
against payments to the POLR Supplier under this Agreement, DLC shall have the
right to offset any amounts the POLR Supplier owes to DLC pursuant to Sections
7.2 and 7.3 hereof (except for such amounts reasonably disputed by the POLR
Supplier), against the amounts owed by DLC pursuant to Section 7.1 hereof. DLC
may exercise the right to offset granted by this Section 7.5 in the amounts and
under the circumstances provided below:

               (a)  If the amount owing to DLC on the invoice to be rendered by
DLC pursuant to Section 7.2 hereof, or the statement of account to be rendered
by DLC pursuant to Section 7.3 hereof, is less than or equal to the balance of
the Escrow Account on the last day of the month (the "Month-End Escrow
Balance"), then any amounts in the Escrow Account up to the amount owing to DLC
on such invoice or statement of account shall be released to DLC as an offset in
satisfaction thereof, and the difference between the Month-End Escrow Balance
and the amount owing to DLC on such invoice or statement of account shall be
released to the POLR Supplier.

               (b)  If the amount owing to DLC on the invoice to be rendered by
DLC pursuant to Section 7.2 hereof, or the statement of account to be rendered
by DLC pursuant to Section 7.3 hereof, is greater than the Month-End Escrow
Balance, then any amounts in the Escrow Account up to the Month-End Escrow
Balance shall be released and retained by DLC as an offset, and DLC may withhold
further payments of Net Billed Generation Revenue otherwise owing to the POLR
Supplier under Section 7.1 hereof as an offset until the difference between the
Month-End Escrow Balance and the amount owing to DLC on such invoice or
statement of account has been fully recovered by DLC.

               (c)  DLC's right to offset Net Billed Generation Revenue under
Section 7.5 (b) shall take precedence over DLC's right to escrow Net Billed
Generation Revenue under Section 7.4 (e) hereof.

          1.28 Right to Immediate Payment and to Draw on Letter of Credit.  In
               ----------------------------------------------------------
addition to the rights to escrow under Section 7.4 hereof and the rights to
offset under Section 7.5 hereof, DLC shall further have the right to immediate
payment from the POLR Supplier, and to draw upon the letter(s) of credit posted
by the POLR Supplier under the terms of this Agreement, in the amounts and under
the circumstances provided below:

                                       37
<PAGE>

               (a)  In each calendar month, as of the date of the invoice
rendered pursuant to Section 7.2 hereof, DLC shall estimate the Net Billed
Generation Revenue that would become payable to the POLR Supplier under Section
7.1 hereof during the remainder of such month (ignoring any potential escrow of
funds pursuant to Section 7.4 hereof or potential offset of funds pursuant to
Section 7.5 hereof). The amount so estimated is defined as the "Residual Monthly
NBGR Estimate."

               (b)  If in any calendar month the sum of the net amount of the
most recent invoice rendered pursuant to Section 7.2 hereof and the net amount
of the most recent statement of account rendered pursuant to Section 7.3 hereof
(and less any offset from the Escrow Account made pursuant to Section 7.5
hereof) is greater than the Residual Monthly NBGR Estimate for the current
month, then the difference between such sum and the Residual Monthly NBGR
Estimate is defined as the "Forecast Supplier Charge Shortfall."

               (c)  DLC may give notice to the POLR Supplier of a Forecast
Supplier Charge Shortfall, and, upon receipt thereof, the POLR Supplier shall
make immediate payment to DLC of the dollar amount of the Forecast Supplier
Charge Shortfall in immediately available funds to the bank account designated
by DLC in Section 15.3 hereof.

               (d)  If, within ten (10) days following notice to the POLR
Supplier given by DLC pursuant to Section 7.6 (c), DLC has not received payment
in full of the Forecast Supplier Charge Shortfall so noticed, then DLC has the
right to draw upon the letter(s) of credit posted by the POLR Supplier under the
terms of this Agreement in an amount up to, but not exceeding, any portion of
the Forecast Supplier Charge Shortfall then unpaid by the POLR Supplier, and,
regardless of whether DLC draws on such letter(s) of credit, DLC shall also have
the right to terminate this Agreement upon ten (10) days written notice to the
POLR Supplier.

     7.7  Payments.  Except as may otherwise be provided in this Agreement,
          --------
beginning on the Closing Date and continuing on each Business Day thereafter
until the end of the term of this Agreement (or the earlier termination of this
Agreement), all payments then due hereunder shall be made to the Party owed such
payments by electronic transmission to the bank account designated by such Party
in Section 15.3 hereof.  All such payments shall be denominated and paid in U.S.
dollars.

                                       38

     7.8  Payment Disputes.  The Parties shall use their good faith best efforts
          ----------------
to resolve all disputes relating to payments hereunder pursuant to the dispute
resolution provisions of Article X of this Agreement.

     7.9  Survival.  Notwithstanding any other provision of this Agreement to
          --------
the contrary, the provisions of this Article VII, and the rights and obligations
of the Parties thereunder, shall survive the expiration of the term of this
Agreement (or earlier termination of this Agreement) for a period not to exceed
one hundred twenty (120) days from the date of the expiration or termination of
this Agreement for the purpose of satisfying the rights and obligations of the
Parties under this Article VII relating to the POLR Supply Service provided
through the date of expiration or termination of this Agreement.

                                 FORCE MAJEURE

          8.1  Force Majeure.  Notwithstanding anything in this Agreement to the
               --------------
contrary, neither Party shall be liable in damages, or otherwise responsible to
the other Party, for its failure to perform or observe any of its obligations
under this Agreement if and only to the extent that it is unable to so perform
or is prevented from performing by an event of Force Majeure; provided, however,
that to the extent that the POLR Supplier fails in any hour to deliver the POLR
Supply Amount in accordance with Section 4.1 hereof, whether as a result of an
event of Force Majeure or for any other reason, the provisions of Section 4.3
hereof shall apply to such failure.  The Parties recognize and agree that an
event of Force Majeure will not relieve any Party of its obligation to make
payments when due hereunder.

          8.2  Definition of Force Majeure.  The term "Force Majeure" as used
               ---------------------------
herein means those causes beyond the reasonable control of the Party affected
that, by the exercise of reasonable diligence, including Good Utility Practice,
such Party is unable to prevent, avoid, mitigate, or overcome, including an act
of God, labor dispute (including a strike), act of the public enemy, war, civil
disturbance, insurrection, riot, fire (unless resulting from the fault or
negligence of the Party asserting Force Majeure), storm or flood, lightning,
explosion (unless resulting from the fault or negligence of the Party asserting
Force Majeure), order, government decree or rule, regulation or restriction
imposed by governmental, military or lawfully-established civilian authorities,
or any other cause of a similar nature beyond such Party's reasonable control.
Events that cause a change in the market value of Energy, the POLR Supplier's
generation costs or otherwise affect the POLR

                                       39
<PAGE>

Supplier's cost of performance under this Agreement shall not be considered
Force Majeure events.

          8.3  Force Majeure Procedures.  Upon the occurrence of an event of
               ------------------------
Force Majeure, the Party affected by such event shall (a) provide prompt written
notice of such Force Majeure event to the other Party, including an estimation
of its expected duration and the probable impact on the performance of its
obligations hereunder; (b) exercise all reasonable efforts in accordance with
Good Utility Practice to continue to perform its obligations under this
Agreement; (c) expeditiously take action to correct or cure the event or
condition excusing performance, provided, however, that settlement of labor
disputes will be completely within the sole discretion of the Party affected by
such labor dispute; (d) exercise all reasonable efforts to mitigate or limit
damages to the other Party; and (e) provide prompt notice to the other Party of
the cessation of the event or condition giving rise to its excuse from
performance.  Any obligation under this Agreement shall be suspended only to the
extent caused by such Force Majeure event and only during the continuance of any
inability of performance caused by such Force Majeure event but for no longer
period.

                            DEFAULT AND TERMINATION

          1.29 Event of Default.  Unless excused by Force Majeure, each of the
               ----------------
following events shall be considered an Event of Default:

               (a)  The material breach by either Party of any agreement,
covenant or obligation under this Agreement; provided that such breach is not
caused by the material breach of the other Party, and provided further that, if
such breach is curable, a default shall not occur until the Party in breach has
failed to cure such breach within thirty (30) days after receipt of written
notice thereof by the non-defaulting Party;

                                       40
<PAGE>

               (b)  The failure by the POLR Supplier to post, supplement,
replace or maintain any letter of credit required to be so posted, supplemented,
replaced or maintained pursuant to the terms of this Agreement; provided that if
the POLR Supplier fails to replace or supplement any letter of credit as
required by the terms of such letter of credit, a default shall not occur unless
the POLR Supplier shall fail to replace or supplement such letter of credit
within ten (10) days of receiving written notice by DLC of such failure;

               (c)  The discovery that any representation, warranty or
certification made by a Party (or the Certifying Company, if applicable)
hereunder was false or misleading in any material respect when made that is not
cured within thirty (30) days and which has a material adverse effect on the
ability of the Party making such representation or warranty to perform its
obligations hereunder;

               (d)  The filing of an involuntary petition in bankruptcy against
either Party (or the Certifying Company) or the appointment of a receiver or
liquidator or trustee for either Party (or the Certifying Company) or of any
substantial part of the property of a Party (or the Certifying Company),
provided that if such Party (or the Certifying Company) is working diligently to
have such petition, receiver, liquidator or trustee stayed, dismissed or
discharged, a default shall not occur unless such petition, receiver, liquidator
or trustee is not stayed, dismissed or discharged within thirty (30) days;

               (e)  The entry of a decree adjudicating a Party (or the
Certifying Company) or any substantial part of the property of a Party (or the
Certifying Company) bankrupt or insolvent, provided that if such Party (or the
Certifying Company) is working diligently to have such decree discharged or
stayed, a default shall not occur unless such decree is continued undischarged
and unstayed for a period of thirty (30) days;

               (f)  The filing of a voluntary petition in bankruptcy under any
provision of any federal or state bankruptcy law by a Party (or the Certifying
Company) or against it;

                                       41
<PAGE>

               (g)  The failure of DLC to pay the POLR Supplier undisputed
amounts owed within ten (10) days after receiving written notice from the POLR
Supplier that any such amount is overdue;

A failure by the POLR Supplier to deliver the POLR Supply Amount in accordance
with Section 4.1 hereof that causes DLC to Shed Load during any hour (other than
any such failure that results from an event of Force Majeure or outages on the
DLC Transmission System or DLC's distribution system), provided that DLC has
requested reasonable assurances from the POLR Supplier that the circumstances
that caused such failure have been corrected and the POLR Supplier has not,
within sixty (60) days of such request, provided DLC with such assurances;

A default by the POLR Supplier (or the Certifying Company) on its indebtedness
to third parties, resulting in obligations of the POLR Supplier (or the
Certifying Company) in an amount of $50,000,000 or more being accelerated;

Termination.  (a)  Upon the occurrence of an Event of Default, the
non-defaulting Party may terminate this Agreement by providing sixty (60) days'
written notice to the defaulting Party of a specified date of termination;
provided, however, that upon the occurrence of an Event of Default specified in
Section 9.1 (d), (e) and (f) hereof, the non-defaulting Party may terminate this
Agreement by delivering to the defaulting Party a written notice of termination,
which termination shall be effective upon the defaulting Party's receipt of such
notice. The non-defaulting Party may exercise all such rights and remedies as
may be available to it to recover damages caused by such Event of Default.

               (b)  If by February 15, 2001 (w) the PUC has failed to issue an
order approving the Retail Tariff set forth on Schedule 2 attached hereto
(unless the failure to approve such Retail Tariff is based solely on the absence
of a definitive effective date for such Retail Tariff) and the Generation Rates
set forth on Schedule 3 attached hereto, (x) the PUC has failed to issue an
order approving modifications to the Supplier Tariff such that each EGS is
responsible for its pro rata allocation of the Residual Losses and Unaccounted
For Energy based on the amount of retail Energy consumed during each hour
(including average losses) attributable to such EGS's load, (y) the FERC has
failed to issue an order, in a form reasonably acceptable to the Parties,
approving the terms and conditions of this Agreement, or (z) the PUC has failed
to issue an order approving the Revised POLR I Retail Tariff, then for a period
not to exceed thirty (30) days thereafter either Party may terminate this
Agreement by providing written notice of such termination to the other Party.
Upon

                                       42
<PAGE>

any such termination, neither Party shall have any further liability to the
other Party under this Agreement.

               (c)  Following the earliest Rate Class Effective Date hereunder,
if:

     (i)   the PUC issues an order requiring a change that will directly or
     indirectly reduce or increase the Generation Rates or that will result in
     any other material change to the Retail Tariff,

     (ii)  the PUC issues an order requiring a change to the Supplier Tariff
     that materially affects the rights or obligations of the Parties as
     provided hereunder,

     (iii) the FERC issues an order requiring a change (other than those changes
     to Schedule 9B to the OATT contemplated hereunder) that materially affects
     the rights or obligations of the Parties as provided hereunder,

     (iv)  there is any change in the rates of any Governmental Charges imposed
     on or with respect to the Parties rights or obligations hereunder, or in
     the manner in which any such Governmental Charges are imposed, in either
     case that materially affects the rights or obligations of the Parties as
     provided hereunder, or

     (v)   the policies of any RTO that DLC joins, or for a region in which the
     POLR Supplier's generation assets are located, differ, or are reasonably
     likely to differ, materially from the terms of this Agreement, and if such
     policies will materially affect either Party to this Agreement, including,
     but not limited to, the imposition of costs or obligations on either Party
     or the ability of either Party to perform its obligations under this
     Agreement, and if the Parties have exhausted their remedies under Section
     III.B.5(b) of that certain Joint Petition for Settlement filed with the PUC
     in Docket No. R-00974104 on November 29, 2000

then, either Party may deliver written notice of the occurrence of any such
event(s) to the other Party (such notice, a "Renegotiation Notice").  Promptly
after the delivery and receipt of a Renegotiation Notice, the Parties shall, in
good faith, attempt to negotiate a mutually satisfactory amendment to this
Agreement to restore the respective rights and obligations of the Parties under
this Agreement as they existed immediately prior to such event(s).  If within
thirty (30) days following the delivery

                                       43
<PAGE>

of any such Renegotiation Notice the Parties fail to agree upon any such
amendment, either Party may then terminate the Agreement by providing the other
Party with fifteen (15) days' prior written notice of such termination. Any
amendment to this Agreement negotiated as a result of a Renegotiation Notice
shall be deemed to be retroactively effective to the date on which the event(s)
described in such Renegotiation Notice occurred; provided, however, that if
following any such event, the order giving rise to such event is no longer in
effect (or is modified in a manner described in clause (i), (ii) or (iii)
hereof) by virtue of a decision by a Governmental Authority that has become
final and non-appealable, then any such amendment shall be of no further force
and effect and this Agreement shall be read so as not to include such amendment
(and in the event such order is modified in a manner described in clause (i),
(ii) or (iii) hereof, the Parties may deliver a Renegotiation Notice with
respect thereto as otherwise contemplated hereunder). Upon any termination
pursuant to this Section 9.2(c), neither Party shall have any further liability
to the other Party under this Agreement, except for any obligations that arose
or accrued prior to the effective date of such termination.

          1.30 Letter(s) of Credit.  Upon the occurrence of an Event of Default
               -------------------
(other than an Event of Default for which DLC is responsible), DLC may draw on
any and all letter(s) of credit posted pursuant to the terms of this Agreement
to cure any monetary default. Unless DLC has given written notice of its intent
to terminate this Agreement, within five (5) Business Days prior to the
expiration of any letter(s) of credit posted pursuant to the terms of this
Agreement, or within ten (10) Business Days of the day on which DLC draws on any
letter(s) of credit posted pursuant to the terms of this Agreement, the POLR
Supplier shall replace such letter(s) of credit with another letter of credit
issued by a Commercial Bank of like amount and in form and substance reasonably
acceptable to DLC.

          1.31 Additional Remedies.  The POLR Supplier acknowledges and
               -------------------
specifically agrees that its obligations under this Agreement are essential to
ensure the reliability of the DLC Control Area; that breach of the POLR
Supplier's obligations may result in irreparable harm and damage to DLC which
cannot adequately be compensated by a monetary award; and that, as a consequence
thereof, DLC shall, in addition to any other remedy to which DLC may be entitled
by reason of the POLR Supplier's breach of this Agreement, be entitled to seek
and obtain temporary, preliminary and permanent injunctive relief from any court
or Governmental Authority of competent jurisdiction restraining the POLR
Supplier from committing or continuing any breach of this Agreement.

          1.32 Reimbursement for Replacement Costs.
               -----------------------------------

          (a)  Upon the termination of this Agreement pursuant to Section 9.2(a)
hereof as a result of any Event of Default, other than those Events of Default
specified in Sections 9.1(d), (e) and (f) hereof, the defaulting Party shall be
liable to the non-defaulting Party for all losses and costs reasonably incurred
by the non-defaulting Party as a direct result of the defaulting Party's Event
of Default, including all reasonable costs associated with replacing the
obligations of the defaulting Party hereunder.

          (b)  Upon the termination of this Agreement pursuant to Section 9.2(a)
hereof as a result of an Event of Default specified in Sections 9.1(d), (e) and
(f) hereof, the defaulting Party shall be liable to the non-defaulting Party for
all of the non-defaulting Party's Losses (as defined in the next sentence) as a
result thereof.  For purposes of this Section 9.5(b), "Losses" means an amount
that the non-defaulting Party, or its agent, determines in good faith and in a
commercially reasonable manner to be the total losses and costs that the non-
defaulting Party has and/or would incur in replacing the obligations of the
defaulting Party for the remaining term of this Agreement.  The non-defaulting
Party, or its agent, may determine such Losses by using pricing or other
valuation models and by reference to information available to it internally or
supplied by one or more third parties (including, without limitation, dealers,
information vendors and other sources of market information), which information
may include, without limitation, quotations (either firm or indicative) of
relevant rates, prices, yields, yield curves, volatilities, spreads or other
relevant market data in the relevant markets.  The defaulting Party shall pay an
amount equal to the Losses to the non-defaulting Party within thirty (30) days
after the defaulting Party receives written notice from the non-defaulting Party
of such amount.

          (c)  In addition to the foregoing amounts, the defaulting Party shall
be liable for reasonable administrative and legal expenses incurred by the non-
defaulting Party as a result of the defaulting Party's Event of Default.  The
Parties expressly agree that the obligations of each Party under this Section
9.5 shall survive and continue in full force following any termination of this
Agreement pursuant to Section 9.2(a) hereof.

                               DISPUTE RESOLUTION

          1.33 Disputes.   A Party with a claim or dispute under this Agreement
               --------
shall submit to the other Party a notification of such claim or dispute within
sixty (60) days of the date on which the Party knew, or should have known, of
the occurrence of the circumstances that gave rise to the claim or the question
or issue in dispute, and shall provide the Administration Committee with a copy
of such notification. Any such notification shall be in writing and shall

specifying the claim, issue or question in dispute. If the Administration
Committee is unable to do so, the Parties shall refer the claim or dispute to
their respective senior management. Subject to Section 10.4 hereof, if, after
using their good faith best efforts to resolve the dispute, the Parties' senior
management cannot resolve the dispute within thirty (30) days, the Parties may,
if they both so agree in writing, utilize the alternative dispute resolution
procedures set forth below in Sections 10.2 and 10.3 hereof.

          1.34 Arbitration.  Any arbitration initiated under this Agreement
               -----------
shall be conducted before a single neutral arbitrator appointed by the Parties
within thirty (30) days of receipt by respondent of the demand for arbitration.
If the Parties are unable to agree on an arbitrator, such arbitrator shall be
appointed by the American Arbitration Association. Unless the Parties agree
otherwise, the arbitrator shall be an attorney or retired judge with at least
fifteen (15) years of experience and shall not have any current or past
substantial business or financial relationships with any Party to the
arbitration. In addition, if possible, the arbitrator shall have significant
system operations experience in the electric industry. Unless otherwise agreed,
the arbitration shall be conducted in accordance with the American Arbitration
Association's Commercial Arbitration Rules, then in effect, in Pittsburgh,

          1.35 Arbitration Terms.  The arbitration shall, if possible, be
               -----------------
concluded not later that six (6) months after the date that it is initiated. The
arbitrator shall be authorized only to interpret and apply the provisions of
this Agreement or any related agreements entered into under this Agreement and
shall have no power to modify or change any of the above in any manner. The
arbitrator shall have no authority to award punitive or multiple damages or any
damages inconsistent with this Agreement. The arbitrator shall, within thirty
(30) days of the conclusion of any hearing, unless such time is extended by
agreement of the Parties, notify the Parties in writing of his or her decision,
stating his or her reasons for such decision and separately listing his or her
findings of fact and conclusions of law. The decision of the arbitrator rendered
in such a proceeding shall be final and binding on the Parties. Judgment on any
award made by the arbitrator may be entered in any court having jurisdiction.

          1.36 FERC Jurisdiction.  Notwithstanding any other provision of this
               -----------------
Agreement to the contrary, nothing in this Agreement shall preclude, or be
construed to preclude, any Party from filing a petition or complaint with FERC
with respect to any arbitrable claim over which FERC has jurisdiction.  In such
a case, the other Party may request FERC to reject or to waive jurisdiction.  If
FERC rejects or waives jurisdiction with respect to all or a portion of such
claim, the portion of such claim not so accepted by FERC may be resolved through
arbitration, as provided in this Agreement.  To the extent that FERC asserts or
accepts jurisdiction over such claim, the decision, findings of fact or order of
FERC shall be final and binding, subject to judicial review under the Federal
Power Act, and any arbitration proceedings that may have commenced with respect
to such claim prior to the assertion or acceptance of jurisdiction by FERC shall
be terminated.

          1.37 Assignment.  The POLR Supplier shall not assign this Agreement
               ----------
in whole or in part, or any of the rights, interests, or obligations hereunder,
without the prior written consent of DLC, which consent shall not be
unreasonably withheld; provided, however, that at any time during the term of
this Agreement, in order to facilitate the POLR Supplier obtaining or
maintaining Exempt Wholesale Generator ("EWG") status, the POLR Supplier may
assign to one of its Affiliates, or to an unaffiliated third party, its
obligations hereunder relating to obtaining Energy on behalf of retail
customers, including providing Company Use Energy to DLC, so long as the POLR
Supplier provides written notice to DLC of any such assignment. For purposes
hereof, the merger, consolidation or sale of all or substantially all of the
assets of the POLR Supplier shall constitute an assignment subject to this
Article XI. It shall not be unreasonable for DLC to refuse to consent to any
assignment by the POLR Supplier to a Person that does not have both an
investment rating equal to or greater than the Minimum Investment Rating and a
Tangible Net Worth equal to or greater than the Minimum Tangible Net Worth or
that, in DLC's reasonable judgment, is otherwise unable to perform the
obligations of the POLR Supplier hereunder.

               Notwithstanding the foregoing, the POLR Supplier, or its
permitted assignee, may assign, transfer, pledge or otherwise dispose of its
rights and interests hereunder to a trustee, lending institution, or other
Person for the purposes of financing or refinancing the POLR Supply Service
opportunity or the generating facilities and other assets associated with the
Asset Sale, including upon or pursuant to the exercise of remedies under such
financing or refinancing, or by way of assignments, transfers, conveyances of
dispositions in lieu thereof; provided, however, that no such assignment or
disposition shall relieve or in any way discharge the POLR Supplier or any such
permitted assignee from the performance of the duties and obligations of the
POLR Supplier under this Agreement. DLC agrees to execute and deliver such
documents as may be reasonably necessary to accomplish any such assignment,
transfer, conveyance, pledge or disposition of rights hereunder for purposes of
such financing or refinancing, so long as DLC's rights under this Agreement are
not materially altered, amended, diminished or otherwise impaired thereby.

               ---------------------------------
merger, consolidation or sale of all or substantially all of the assets of the
POLR Supplier), transfer, conveyance, pledge or disposition of rights,
interests, duties or obligations under this Agreement by a Party shall relieve
that Party from liability and financial responsibility for the performance
thereof after any such transfer, assignment, conveyance, pledge or disposition
unless and until (i) the transferee or assignee shall agree in writing to assume
the obligations and duties of that Party under this Agreement and, in the case
of the transferee or assignee of the POLR Supplier, certify in writing that it
has either an investment rating equal to or greater than the Minimum Investment
Rating or a Tangible Net Worth equal to or greater than the Minimum Tangible Net
Worth and (ii) the non-assigning Party has consented in writing to such
assumption and to a release of the assigning Party from such liability, such
consent not to be unreasonably conditioned, delayed or withheld.

without the prior written consent of the other Party, unless otherwise provided
hereunder, and (iii) agrees to use such information only for such purposes and
in such manner as is contemplated by the terms of this Agreement.

related to this Agreement, including any such damages which are based upon
