applicable Taxes (if any) in accordance with Section 23.02. Except as specified
in Section 5.05, Purchaser will be entitled to the Net Electric Energy produced
during each such Shutdown. The Shutdown fuel requirements and associated Energy
during Shutdown are set forth in Exhibit 5.03.

      5.04 TECHNICAL INSPECTION

      Independence agrees to maintain and to make available to Purchaser
records, including those under the control of Independence or any third party
owner of the Facility and any relevant records otherwise within Independence's
control or ability to obtain, necessary to verify Contract Tolling Capability,
Target Tolling Capability, Force Majeure and any other rights and obligations
hereunder, including, but not limited to data, engineering specifications, test
results or any other information used in connection with any computation,
calculation or formulae set forth in this Agreement. Further, Independence
agrees that Purchaser representatives, upon three Days' prior written notice,
may visit the Facility during Regular Business Hours.

      5.05 RESERVED CAPABILITY

            (a) Subject to the terms and provisions of the Energy Management
Agreement, this Section 5.05 and Exhibits 5.02(A) and 5.02(B), Independence
shall have the right to operate the Facility utilizing all or any portion of the
electrical output associated with the Reserved Capability. At such times,
Independence shall be responsible for all costs associated with operation of the
Facility utilizing all or any portion of the electrical output associated with
the Reserved Capability, and Independence shall be entitled to all revenues
associated with the sale of Energy from the Facility utilizing all or any
portion of the electrical output associated with the Reserved Capability
(including the sale of all Energy produced during Start-up and Shutdown). In the
event that, absent Independence's operation of the Facility utilizing all or any
portion of the electrical output associated with the Reserved Capability, NYISO
Directed Operations to provide Tolling Services to Purchaser would require a
Start-up, such Start-up shall be counted as a Start-up pursuant to Sections 4.05
and 5.01.

            (b) Notwithstanding Section 5.05(a) or any other provision of this
Agreement, but subject to the requirements of Exhibit 5.02(B), the Parties
acknowledge that there may be some periods during the term of this Agreement
where Independence desires to deliver all or a portion of the Reserved Tolling
Capability to the NYISO for purposes of effectuating a physical hedge against
its financial obligations associated with the Market Price. If during such
periods, there

                    *** CONFIDENTIAL TREATMENT REQUESTED ***

                                       18
<Page>

exist contractual limitations on Independence's ability to deliver such portion
of the Reserved Tolling Capability either arising under the provisions of this
Agreement or the provisions of the Energy Management Agreement, such that
Independence is prevented from delivering such portion of the Reserved Tolling
Capability, then Purchaser shall pay to Independence an amount equal to the
difference between (i) the sum of the products of, for each hour during such
period (A) the Market Price multiplied by (B) such portion of the Reserved
Tolling Capability minus (ii) the revenues actually received by Independence
from the NYISO for sales of Energy associated with such portion of the Reserved
Tolling Capability; and provided further that if Independence notifies Purchaser
of its desire to operate the Facility at the Minimum Output Requirement,
Purchaser must cause the Minimum Output Requirement to operate. The foregoing
provisions are an acknowledgement of the obligations of Purchaser, as Energy
Manager, under the Energy Management Agreement to cause the dispatch of the
Reserved Tolling Capability in a manner consistent with the desires of
Independence, and if such obligations are not fulfilled, the foregoing
establishes a remedy under this Agreement for such circumstance. Purchaser shall
make such payments at the same time any other payments are due under this
Agreement.

            (c) The Parties acknowledge and agree that any and all references in
this Agreement, the Gas Supply Agreement, the Energy Management Agreement and
any other agreement between Independence and Purchaser (and any of Purchaser's
Affiliates) to Independence's effectuating a physical hedge against its
financial obligations associated with the Market Price (i) refer exclusively to
the operation of all or a portion of the Reserved Tolling Capability and (ii)
shall not be construed as implying that Independence shall have any obligation
to obtain Energy from any other source or to take any other action to effectuate
a physical hedge against its financial obligations associated with the Market
Price.

            (d) From time to time during the term of this Agreement,
Independence may have available certain quantities of As Available Energy
(defined below) that Independence is willing to make available to Purchaser.
Independence shall make As Available Energy available to Purchaser during the
"As Available Periods." The "As Available Periods" shall mean those hours during
which (i) Independence is not utilizing any of the Reserved Tolling Capability
for purposes of effectuating a physical hedge against its financial obligations
associated with the Market Price and (ii) Independence has nevertheless elected
to operate a portion of the Reserved Capability at the Minimum Output
Requirement. "As Available Energy" means an amount of Energy available from the
Facility by virtue of Independence's election to operate a portion of the
Reserved Capability at the Minimum Output Requirement, but represents a quantity
equal to the difference between the hourly amount available from one combustion
turbine/generator set in combined cycle mode at maximum output and the amount
attributable to the Minimum Output Requirement. Aside from the determination
that condition (i) of the preceding sentence has been satisfied, Independence
shall advise Purchaser in

                    *** CONFIDENTIAL TREATMENT REQUESTED ***

                                       19
<Page>

accordance with the procedures specified in Exhibit 5.02(A) of the number of
hours that the Facility will operate at the Minimum Output Requirement and
accordingly, the duration of the As Available Period. The As Available Period
must continue for the duration of the period specified in the notice delivered
by Independence in accordance with Exhibit 5.02(A). Subject to the Scheduling
and Operating Procedures specified in Exhibits 5.02(A) and 5.02(B) (and, in
particular, the limitation on changes in output specified as Item 6(e) to
Exhibit 5.02(B), Part I), following the establishment of the As Available
Period, Purchaser may, no later than ten (10) minutes prior to the top of each
hour during the As Available Period, provide Independence with telephonic notice
of Purchaser's desire to receive As Available Energy for the next following hour
of the As Available Period. Subject to the Scheduling and Operating Procedures
specified in Exhibits 5.02(A) and 5.02(B) (and, in particular, the limitation on
changes in output specified as Item 6(e) to Exhibit 5.02(B), Part I), Purchaser
may select all, any individual, or any combination of hours contained in an As
Available Period as the hours in which Purchaser will require the delivery of As
Available Energy. Purchaser may designate the hours in which Purchaser will
require the delivery of As Available Energy in a single communication to
Independence or in a series of individual hourly communications; provided that
in any event, Purchaser may change its election for any hour as long as the
change is communicated to Independence no later than ten (10) minutes prior to
the upcoming hour for which the change will apply.

            (e) As Available Energy shall for all purposes under this Agreement,
be deemed to be Energy resulting from the provision of Tolling Services. Thus,
Purchaser shall arrange for delivery of Gas required for the provision of As
Available Energy in the manner prescribed by Article VIII. In addition,
Independence and Purchaser acknowledge that the As Available Energy does not
contemplate any related Capacity component and no Capacity is being made
available with respect to the As Available Energy either as Contract Tolling
Capability or otherwise. The Fixed Tolling Services Payment shall be unaffected
by the provision of As Available Energy. The calculation of the Variable Tolling
Services Payment shall include any deliveries of As Available Energy when the
monthly quantities of Energy delivered to Purchaser are multiplied times the
Variable Tolling Services Charge, provided that with respect to the quantity of
As Available Energy only, the monthly Variable Tolling Services Payment shall be
increased by an amount equal to the product of a constant of $[***] per MWh
multiplied by the MWh of As Available Energy delivered to Purchaser during such
Month. The provision of As Available Energy and the applicable hours of the As
Available Period during which As Available Energy is provided shall be
considered circumstances during which Independence is providing Tolling Services
and as a result, the calculations described in Section 4.05 shall apply to the
As Available Energy; provided, however, that the applicable hours of the As
Available Period during which As Available Energy is provided shall not be
considered for purposes

                    *** CONFIDENTIAL TREATMENT REQUESTED ***

                                       20
<Page>

of the annual comparison pursuant to the last sentence of Section 4.05. No
Start-up shall be incurred during any As Available Period.

            (f) The Parties expressly acknowledge and agree that Independence
shall not be responsible to Purchaser for any liabilities or costs resulting
from the occurrence of an Outage that reduces the amount of As Available Energy
during an As Available Period, and that nothing in these Sections 5.05(d), (e)
and (f) shall have any effect on the calculation of the Annual Capability
Adjustment pursuant to Section 7.01.

      5.06 INSTALLED CAPACITY TESTING

            From time to time, Independence may perform any Installed Capacity
tests required pursuant to the NYISO Requirements. The Parties shall use
commercially reasonable efforts to schedule such tests during periods when the
Facility is otherwise expected to operate in a manner which conforms to the
requirements of any such tests. Independence may, however, elect to conduct such
tests when the Facility is not otherwise expected to operate in such manner and
the Parties shall cause the Facility (through the submission of bids or
otherwise) to operate in such manner. Independence shall be responsible for any
incremental costs and shall be entitled to any incremental revenues associated
with such testing.

      5.07 GOOD ELECTRICAL PRACTICES

            Subject to Section 10.02, Independence shall at all times operate
the Facility in accordance with Good Electrical Practices.

      5.08 OPERATING COMMITTEE

            The Parties shall each appoint a member and an alternate to an
Operating Committee, and so notify the other Parties of such appointments in
writing. Such appointments may be changed at any time by similar notice. The
Operating Committee shall meet as necessary to carry out the duties set forth
herein. The Operating Committee shall hold meetings at the request of any Party
at the Facility (unless otherwise agreed upon by the members of the Operating
Committee) and at a time agreed upon by the members of the Operating Committee.
Each member and alternate shall be a responsible person working with his or her
Party's respective day-to-day operations under this Agreement. The duties of the
Operating Committee shall include, but not be limited to, (i) coordinating
operation schedules, (ii) establishing and maintaining operating procedures,
including those pertaining to information transfers between and among the
Parties, consistent with the provisions of this Agreement, and (iii) such other
duties as may be conferred upon it by mutual agreement of the Parties.

      5.09 UNIT OUTAGES

            Each time, following completion of a Start-up and prior to
commencement of the next Shutdown, a combustion turbine/generator set operating
in combined cycle mode suffers an Outage, Independence shall pay Purchaser
$[***].

                       ARTICLE VI - GUARANTEED HEAT RATE

      6.01 GUARANTEED HEAT RATE

      The Guaranteed Heat Rate for any hour is the Heat Rate indicated in the
table contained in Exhibit 6.01 for the actual output level of the Facility
(including the output level associated with the provision of Tolling Services
plus the output level associated with the use of the Reserved Capability) for
such hour (in MW). The Guaranteed Heat Rate for part loading conditions is as
set forth in Exhibit 6.01.

      6.02 HEAT RATE

      At the conclusion of each Month, Independence shall calculate the
Guaranteed Heat Rate Gas Differential (GHRGD), where:

            GHRGD = (Actual Gas) - (Target Gas);

            Actual Gas = the difference for such Month between (a) actual
            quantities of Gas supplied pursuant to this Agreement and the Gas
            Supply Agreement and used by the Facility (expressed in MMBtu and
            measured utilizing the Gas Metering Equipment) minus (b) the
            quantities of Gas purchased or deemed purchased by Independence
            pursuant to Section 8.01(b) of this Agreement and pursuant to the
            Gas Supply Agreement; and

            Target Gas = the sum of (a) for each Start-up during the Month, the
            Start-up Gas guaranteed in Exhibit 5.01, plus (b) for each Shutdown
            during the Month, the Shutdown Gas guaranteed in Exhibit 5.03, plus
            (c) the sum for all hours during the Month after the completion of
            Start-up and prior to Shutdown of the Facility of the product of (i)
            the Guaranteed Heat Rate for such hour (expressed in Btu of Gas
            consumed per kWh) multiplied by (ii) the actual Net Electric Energy
            produced during such hour.

                    *** CONFIDENTIAL TREATMENT REQUESTED ***

      6.03 PAYMENT

      If the Guaranteed Heat Rate Gas Differential is positive, Independence
shall pay Purchaser the product of the Guaranteed Heat Rate Gas Differential,
increased to reflect Empire, Niagara Mohawk, TransCanada Pipelines Limited
(between Kirkwall and Chippawa) and Union Gas Limited (between Dawn and
Kirkwall) fuel, shrinkage and loss, multiplied by a rate equal to the sum of the
Monthly Gas Index Price plus variable Gas transportation costs (per MMBtu) under
the Niagara Mohawk Gas Transportation Contract and the Empire Gas Transportation
Contract and variable Gas transportation costs (per MMBtu) under firm
transportation capacity on the system of TransCanada Pipelines Limited between
Kirkwall and Chippawa and firm transportation capacity on the system of Union
Gas Limited between Dawn and Kirkwall and applicable Taxes (if any) in
accordance with Section 23.02. If the Guaranteed Heat Rate Gas Differential is
negative, Purchaser shall pay Independence the product of the Guaranteed Heat
Rate Gas Differential (expressed as a positive number), increased to reflect
Empire, Niagara Mohawk, TransCanada Pipelines Limited (between Kirkwall and
Chippawa) and Union Gas Limited (between Dawn and Kirkwall) fuel, shrinkage and
loss, multiplied by a rate equal to the sum of the Monthly Gas Index Price plus
variable Gas transportation costs (per MMBtu) under the Niagara Mohawk Gas
Transportation Contract and the Empire Gas Transportation Contract and variable
Gas transportation costs (per MMBtu) under firm transportation capacity on the
system of TransCanada Pipelines Limited between Kirkwall and Chippawa and firm
transportation capacity on the system of Union Gas Limited between Dawn and
Kirkwall and applicable Taxes (if any) in accordance with Section 23.02.

      6.04 EXCLUSIVE NATURE OF COMPENSATION

      The Parties expressly acknowledge and agree that the adjustment provided
in accordance with this Article VI constitutes the exclusive compensation of the
Parties for variations in Heat Rate and that the failure to achieve the
Guaranteed Heat Rate shall not constitute an Event of Default hereunder.

                  ARTICLE VII - GUARANTEED TOLLING CAPABILITY

      7.01 CALCULATION OF GUARANTEED TOLLING CAPABILITY

      An additional payment to or from Independence shall be made after the end

      8.07 EFFECT OF DELIVERY; INDEMNITY

      Title to all Gas delivered pursuant to Section 8.01(b) shall pass to
Independence at the Gas Delivery Point. As between the Parties, Purchaser shall
be deemed to be in exclusive control and possession of the Gas delivered
hereunder until the same shall have been delivered at the Gas Delivery Point, at
and after which delivery Independence shall be deemed to be in exclusive control
and possession thereof. Purchaser and Independence each assumes full
responsibility and liability for and shall indemnify and save harmless the other
Party and its officers, directors, employees, agents, and partners from all
liability and expense on account of any and all damages, claims, or actions,
including injury to and death of Persons, arising from any act or accident
occurring when title to the Gas is vested in the indemnifying Party as herein
provided.

      8.08 TRANSPORTER'S SPECIFICATIONS

      Gas delivered by Purchaser shall meet or exceed the minimum quality
specifications under the Empire Gas Transportation Contract (and related Empire
Gas tariffs) and the Niagara Mohawk Gas Transportation Contract (and related
Niagara Mohawk Gas tariffs). If any Gas delivered by Purchaser shall fail to
conform to such quality specifications, Independence's sole remedy shall be
refusal to accept the tendered quantities, in which event such Gas shall be
treated as if Purchaser shall have failed to deliver it; all other Gas shall be
treated as meeting such specifications. Gas delivered by Purchaser shall be
delivered at pressures sufficient to cause such Gas to enter Independence's
facilities at the Gas Facility Point, but not below the minimum allowable or
above the maximum allowable operating pressure specified in the Empire Gas
Transportation Contract (and related Empire Gas tariffs) and the Niagara Mohawk
Gas Transportation Contract (and related Niagara Mohawk Gas tariffs).

      8.09 GAS SUPPLY OBLIGATIONS

      9.01 SCHEDULED OUTAGES

            (a) Scheduled Outages will be scheduled and permitted as follows:

                    *** CONFIDENTIAL TREATMENT REQUESTED ***

                                       29
<Page>

                  (i) Within ten Days following the Effective Date, on or before
September 15, 2001 and thereafter prior to September 15 of each subsequent
Contract Year, Independence will provide to Purchaser a non-binding forecast
schedule of Scheduled Outages of the Facility for each Month. Such non-binding
forecast schedule will cover the period of time occurring (A) in the case of the
notice delivered within ten days after the Effective Date, from the Effective
Date through December 31, 2001, (B) in the case of the notice delivered on or
before September 15, 2001, from January 1, 2002 through December 31, 2002, and
(C) in the case of each subsequent notice, the following Contract Year. Within
30 Days of receipt of the forecast schedule, Purchaser may provide Independence
with comments on the forecast. Independence will make commercially reasonable
efforts to accommodate Purchaser's comments. No later than thirty Days following
the receipt of Purchaser's comments, Independence will submit to Purchaser its
schedule for Scheduled Outages for the period, which schedule will include the
number of generation turbines to be included in each Scheduled Outage. In no
event, without Purchaser's consent, will such schedule provide for a Scheduled
Outage during the months of June, July, August, September, December, January or
February.

                  (ii) Either Party may request a change in the schedule for a
Scheduled Outage by delivering a notice to the other Party at least 60 Days
prior to the start of such Scheduled Outage. The Parties will use commercially
reasonable efforts to accommodate such requests, provided that Independence will
in no event be required to accept such request if the implementation of the
requested schedule change could, in Independence's reasonable judgment,
invalidate or impair Independence's equipment warranties or insurance policies
or the success of any claims to be made thereunder, increase the cost to
Independence of performing maintenance or affect the quality of such
maintenance, cause Independence's actions or performance hereunder to deviate
from Good Electrical Practices or prevent Independence from meeting its
obligations under this Agreement.

            (b) Notwithstanding any other provision of this Section 9.01,
Independence may schedule or reschedule a Scheduled Outage at any time if
required, in Independence's reasonable judgment, by Good Electrical Practices or
pursuant to NYISO Requirements. Independence shall provide Purchaser with as
much notice of such Scheduled Outages as practicable under the circumstances. If
Independence desires to schedule or reschedule a Scheduled Outage during June,
July, August, September, December, January or February, Independence will, if
practicable, discuss with Purchaser the timing of such a Scheduled Outage and
will consider any reasonable requests by Purchaser to modify the timing for such
a Scheduled Outage.

      9.02 FORCED OUTAGES

      Any outage or unavailability of all or a portion of the Contract Tolling
Capability, other than due to Force Majeure, breach by Purchaser or a Scheduled

Outage shall constitute a Forced Outage. The Parties expressly acknowledge and
agree that the existence of a Forced Outage shall not constitute an Event of
Default hereunder. In the event of a Forced Outage, Independence shall use
commercially reasonable efforts to remedy the cause(s) and effect(s) of such
Forced Outage with all reasonable dispatch, including, if necessary, the
reconstruction, repair or replacement of all or a portion of the Facility
utilizing the proceeds of insurance required pursuant to Article XV.

                 ARTICLE X - NYISO AND REGULATORY REQUIREMENTS

      10.01 NYISO BIDDING

            (a) Subject to Section 10.01(b) and the applicable Scheduling and
Operating Procedures specified in Exhibits 5.02(A) and 5.02(B) and except as

adjustment under the NYISO Services Tariff, the ConEd Agreement or any Residual
Installed Capacity Agreement.

                  (ii) For any period during which Purchaser is supplying
Replacement Capacity to ConEd or to any other purchaser under a Residual
Installed Capacity Agreement on Independence's behalf and with Independence's
consent pursuant to Section 10.01(c)(i), Purchaser shall be entitled to the
Installed Capacity from the Facility up to the level of the Replacement Capacity
supplied and the requirements of Section 10.01(a) shall not apply with respect

Independence reasonably believes that the provision of Replacement Capacity to
ConEd or to any other purchaser under a Residual Installed Capacity Agreement
shall fail to satisfy any of the three conditions listed in Section 10.01(c)(i),
Independence shall be entitled to immediately take the Installed Capacity from
the Facility back from Purchaser and the requirements of Section 10.01(a) shall
once again apply with respect to such Installed Capacity. During the Contract
Term, in addition to other indemnification obligations of Purchaser set forth
elsewhere in this Agreement, Purchaser shall indemnify and hold Independence
harmless from and against any and all liabilities, costs, claims, causes of
action, judgments, lawsuits, or damages (including any penalties, deficiency
charges or price adjustments under the ConEd Agreement) that may be incurred by
Independence in connection with the failure of Replacement Capacity to satisfy
any of the three conditions listed in Section 10.01(c)(i).

                  (iv) For any period during which Purchaser is supplying
Replacement Capacity to ConEd or to any other purchaser under a Residual
Installed Capacity Agreement on Independence's behalf and with Independence's
consent pursuant to Section 10.01(c)(i), the Parties expressly acknowledge and
agree that Independence shall be entitled to receive directly all amounts
payable under the ConEd Agreement or such Residual Installed Capacity Agreement
and Purchaser hereby waives any right, title or interest to any such amounts
payable.

                  (v) Independence agrees to incorporate provisions in all
negotiated Residual Installed Capacity Agreements entered into during the
Contract Term to permit Independence or its designated agent to supply Installed
Capacity from sources other than the Facility. If Independence elects to sell

                    *** CONFIDENTIAL TREATMENT REQUESTED ***

                                       32
<Page>

Installed Capacity from the Facility through an auction process, Independence
shall notify Purchaser of its intent at least 15 Days prior to the deadline for
participation in such auction; it being understood that the first sentence of
this Section 10.01(c)(v) shall not apply to any sales of Installed Capacity
through an auction process.

      10.02 PURCHASER REQUIREMENTS

      Purchaser shall not issue any notices, instructions or schedules
inconsistent with this Agreement, any applicable operating policies, criteria
and/or guidelines of NERC, NYISO, any other regional or subregional operational
and reliability requirements or any other applicable Laws, or that would result
in NYISO Directed Operations that are inconsistent with Good Electrical
Practices. If Purchaser issues a notice, instruction or schedule in
contravention of the preceding sentence, Independence shall have no obligation
to comply with such notice, instruction or schedule. Any NYISO Directed
Operation that requires Independence to Start-up or Shutdown or otherwise
affects the operation of the Facility shall be treated under this Agreement as
if such direction had been issued by Purchaser, and Purchaser shall supply Gas
as required for Independence to comply with such NYISO order, and Purchaser
shall be entitled to all revenues from sales resulting from such NYISO order and
Independence shall be entitled to payment in accordance with Article IV (except
as specified in Sections 5.05 and 8.02). Independence shall comply with NYISO
Directed Operations that are not consistent with Good Electrical Practices only
during NYISO system emergencies. In the event that a Party receives notice of a
change or proposed change to the NYISO Requirements that would require a Party
to take or refrain from taking an action that would be inconsistent with such
Party's rights and/or obligations hereunder, the Party receiving notice will
promptly notify the other Party to the extent practicable that such NYISO
Requirement conflicts with the rights and/or obligations of a Party under this
Agreement and the Parties agree to promptly meet and negotiate in good faith an
agreement as to how compliance shall be established and maintained, attempting
in all events to restore or maintain for each Party as nearly as possible, its
respective rights, obligations and benefits under this Agreement provided that
such compliance shall not result in significant economic impact to the Parties.
The failure of the Parties to reach any such agreement shall not result in
termination of this Agreement or relieve any Party of its obligations to make
payments in accordance with this Agreement. Subject to any such agreement,
Independence and Purchaser shall each comply with all NYISO Requirements and
shall deviate (except for the payment of money for which there shall be no
deviation) from the provisions of this Agreement to the minimum extent necessary
in order to comply with such NYISO Requirements. During the Contract Term, in
addition to other indemnification obligations of Purchaser set forth elsewhere
in this Agreement, Purchaser shall indemnify and hold Independence harmless from
and against any and all liabilities, costs, claims, causes of action, judgments,
lawsuits, or damages that may be incurred by Independence as a result of
Purchaser's failure to meet its obligations under this Section 10.02.

written agreement of both Parties as provided above. Either Party shall, as and
if requested by the other Party, support this Agreement in filings and with
testimony in any administrative or judicial proceeding relating to or in
connection with this Agreement.

            (b) Except as provided in this Section 10.04, nothing in this
Agreement shall limit the ability of the Parties to participate in regulatory
proceedings. To the extent permitted by law, if a Party desires to participate
in a generic rulemaking or similar regulatory proceeding, the Parties may
participate in their own right or may cause Affiliates to participate in such
proceedings in lieu of direct participation by the Parties; provided that if a
Party determines, in its reasonable judgment, that its rights cannot be
adequately protected except through direct participation by such Party, the

<Page>

Purchaser pursuant to the terms of this Agreement. Monthly payments under this
Agreement for any partial Month during the Contract Term will be prorated.

      12.02 PAYMENT

      Each Party shall render payment to the other Party by wire transfer
payment, or other acceptable method agreed to by the Parties, of the amount due
as set forth in the invoice, by the later of (i) the twenty fifth (25th) Day of
the Month, and (ii) ten Days after the other Party's receipt of the invoice. The
address, account information and/or wire transfer information shall be as
provided pursuant to Section 24.07. Failure to make such payment when due shall
result in a late charge on the unpaid balance that shall accrue on each calendar

good faith disputes any part of any invoice, it shall make payment of the
undisputed amount invoiced and shall provide to the other Party on or before the
payment due date a written explanation of the basis for the dispute. If any
amount disputed is determined to be due, the disputing Party shall pay such
disputed amount within two Days of such determination, along with interest
accrued daily at the Interest Rate from the date that, but for the dispute,
payment was due until the date paid.

      12.03 AUDIT

      Each Party has the right with reasonable prior notice, at its sole
expense, to examine the records of the other Party during Regular Business Hours
to the extent reasonably necessary to verify the accuracy of any invoice, or
calculations provided with or supporting such invoice, rendered pursuant to this
Agreement. If any such examination reveals any inaccuracy in any invoice, or
calculations provided with or supporting such invoice, the necessary adjustments
in such invoice, or calculations provided with or supporting such invoice, and
the payments made pursuant to such inaccurate invoice, or calculations provided
with or supporting such invoice, shall be adjusted in the next invoice;
provided, however, that the party asserting the need for such adjustment brought
it to the attention of the other Party within twelve Months after the event
causing the need for adjustment. This Section 12.03 shall survive any
termination of this Agreement for a period of one year from the date on which
the last invoice is rendered to such Party pursuant to this Agreement.

      12.04 NYISO REIMBURSEMENT

      If and to the extent the NYISO pays Independence directly for Energy or
Ancillary Services to which Purchaser is entitled in accordance with Article
III, Independence shall forward such payments to Purchaser within five Days of
receipt. If the NYISO subsequently adjusts any such payment, Independence shall
forward such adjustment to Purchaser within five days of receipt (in the case of
an additional payment from the NYISO), and Independence shall include the amount
of such adjustment in the next billing statement to Purchaser (in the case of an

                    *** CONFIDENTIAL TREATMENT REQUESTED ***

required to be maintained.

            (b) All such insurance policies maintained by Independence will:

                  (ii) provide that Purchaser will receive from each insurer 30
                  Days' prior written notice of non-renewal, cancellation of, or

                  such notice period will be 10 Days in case of non-payment of
                  premiums); and

                  (iii) provide a waiver of any rights of subrogation against
                  Purchaser, its Affiliates and their officers, directors,

      The insurance certificates will indicate that the insurance policies have
been endorsed as described above.

            (c) All policies maintained by Independence will be written by one
or more nationally reputable insurance companies approved to do business in New
York and be rated B+VII or higher by A.M. Best Company or Lloyds Companies or

occurrence basis unless procured from AEGIS on a claims made basis. Policies
will contain an endorsement that Independence's policy will be primary as
respects

                    *** CONFIDENTIAL TREATMENT REQUESTED ***

                                       41

construction and operations of the Facility regardless of like coverages, if
any, carried by Purchaser.

            (e) Purchaser may request Independence to require that any insurance
obtained and maintained by a third party operator of the Facility name Purchaser
as an additional insured, with any cost for such coverage payable by Purchaser.

            (f) Independence will notify Purchaser of the insurance company (and
any replacement thereof) from which Independence obtains its Commercial or
Comprehensive General Liability insurance and, if Purchaser desires to obtain
Commercial or Comprehensive General Liability insurance from the same insurance
company (or any replacement thereof), Independence will comply with Purchaser's
reasonable requests for information concerning such coverages which assist
Purchaser in obtaining insurance from the same such insurance company.

            (g) In the event that (i) the third party liability insurance
required above or (ii) the Excess/Umbrella Liability insurance required, is on a
"claims made" basis and not on an occurrence basis, such insurance will provide
for a retroactive date and continuing "tail" coverage not later than the
Effective Date and such insurance will be maintained by Independence, with a
retroactive date not later than the retroactive date required above, for a
minimum of three years after the Contract Term.

            (h) In the event that Independence reasonably determines that any
such policy of insurance is no longer available at commercially reasonable
rates, Independence shall not be obligated to continue to carry such insurance,
and shall obtain substitute insurance which is as nearly identical as possible
to the policy of insurance which it is intended to replace.

            (i) Purchaser shall at all times effect, maintain and keep in force,
or cause to be effected, maintained and kept in force, comprehensive general
liability insurance, public liability coverage and property insurance for
injuries to persons and property, automobile liability insurance and workman's
compensation insurance, all in commercially reasonable amounts and terms. In the
event that Purchaser reasonably determines that any such policy of insurance is
no longer available at commercially reasonable rates, Purchser shall not be
obligated to continue to carry such insurance, and shall obtain substitute
insurance which is as nearly identical as possible to the policy of insurance
which it is intended to replace.

                     ARTICLE XIX - LIMITATION OF LIABILITY

      19.01 LIMITATION OF LIABILITY

            (a) Subject to Section 19.01(b), neither Party, nor their respective
officers, directors, partners, agents, employees or Affiliates, shall be liable
to the other Party or its Affiliates, officers, directors, trustees, partners,
agents, employees, successors or assigns, for claims for incidental, special,
indirect, consequential or punitive damages of any nature connected with or
resulting from performance or breach of this Agreement, including, without
limitation, claims in the nature of lost revenues, income or profits (other than
payments specifically provided for and properly due under this Agreement) or
losses, damages or liabilities under any financing, lending or construction
contracts, agreements or other arrangements, irrespective of whether such claims
are based upon warranty, negligence, strict liability, contract, operation of
law or otherwise. Under no circumstances shall Independence be liable to
Purchaser for damages associated with the costs to Purchaser to obtain
replacement Energy, Capacity or Ancillary Services to meet Purchaser's
contractual obligations to third parties. The Parties

                    *** CONFIDENTIAL TREATMENT REQUESTED ***

                                       46
<Page>

acknowledge and agree that the services to be provided hereunder are contingent
on the availability of the Facility.

            (b) Notwithstanding the limitation of liability under Section
19.01(a), if Purchaser (i) fails for any reason (including as a result of Force
Majeure) to deliver Gas to the Gas Facility Point or (ii) fails for any reason
(including as a result of Force Majeure) to cause the Reserved Tolling
Capability to be dispatched by the NYISO in accordance with Section 5.05(b), in
each case, during all or any portion of a period in which Independence desires
to operate any portion of the Reserved Tolling Capability for purposes of
effectuating a physical hedge against its financial obligations associated with
the Market Price (during which such portion of the Reserved Tolling Capability
is otherwise available), Purchaser shall pay to Independence the Market Price
for all quantities of Energy that would have been delivered to the Electric
Delivery Point but for the Purchaser's failure (i) to deliver Gas for such
period or (ii) to cause the Reserved Tolling Capability to be dispatched by the
NYISO in accordance with Section 5.05(b). The Parties acknowledge that damages
for such failure to deliver Gas or to cause the Reserved Tolling Capability to
operate are difficult or impossible to determine or otherwise obtaining an
adequate remedy is inconvenient and the damages calculated under this Section
19.01(b) constitute a reasonable approximation of the harm or loss.

      19.02 DUTY TO MITIGATE

      Notwithstanding any other provision of this Agreement, each Party has a
duty to mitigate damages and covenants that it will use commercially reasonable
efforts to minimize any damages it may incur as a result of the other Party's
performance or non-performance.

Affiliates and their officers, trustees, directors, employees and agents from
and against any and all claims, demands, suits, losses, damages, liabilities,
costs and expenses (including reasonable attorney's fees and costs of
investigation) for damage to the tangible property of third parties and injury
to or death of persons (other than Purchaser's employees and Independence's
employees) to the extent caused by, arising out of or relating to the gross
negligence or willful misconduct of Independence in connection with or resulting
from Independence's performance or breach of this Agreement.

      Purchaser shall indemnify, defend and hold harmless Independence and its
Affiliates and their officers, directors, trustees, employees and agents from
and against any and all claims, demands, suits, losses, damages, liabilities,
costs and expenses (including reasonable attorney's fees and costs of
investigation) for damage to tangible property of third parties and injury to or
death of persons (other than Independence's employees or Purchaser's employees)
to the extent caused by, arising out of or related to the gross negligence or
willful misconduct of Purchaser in connection with or resulting from Purchaser's
performance or breach of this Agreement.

      20.03 INDEMNIFICATION PROCEDURES

            (a) A Party which becomes entitled to indemnification under this
Agreement (the "Indemnified Party") shall give written notice to the other Party
(the "Indemnifying Party") of the occurrence of the events which give rise to
such right of indemnification within 30 Days of the Indemnified Party becoming
aware of the occurrence thereof. Such notice shall describe the claim, the basis
thereof and shall indicate an estimate of the amount of the claim. To the extent
that the Indemnifying Party is prejudiced by any failure of the Indemnified
Party to provide such notice, such notice shall be a condition precedent to the
liability of the Indemnifying Party under this Article XX.

            (b) At the Indemnified Party's request, the Indemnifying Party
shall, at its cost and expense, defend (with counsel reasonably acceptable to
the Indemnified Party) any suit asserting a claim against the Indemnified Party
with respect to which the Indemnified Party is entitled to indemnification
hereunder, and shall pay all costs and expenses incurred by the Indemnified
Party to enforce its right to indemnification. The Indemnified Party may, at its
own expense, retain separate counsel and participate in the defense of any such
suit. Neither Party may settle or compromise a claim or suit without the consent
of the Indemnifying Party, which consent shall not be unreasonably withheld or
delayed.

      20.04 SURVIVAL

      The indemnification obligations of each party under this Article XX shall
not be limited in any way by any limitation on insurance, by the amount or types
of damages, or by any compensation or benefits payable by the parties under
Worker's Compensation Acts, disability benefit acts or other employee acts or
otherwise. The provisions of this Article XX shall survive termination,
cancellation, suspension, completion or expiration of this Agreement.

            (a) This Agreement and all of the provisions hereof shall be binding
upon, and inure to the benefit of, the Parties hereto and their respective
successors and permitted assigns, but neither this Agreement nor any of the
rights, interests or obligations hereunder shall be assigned, except to an
Affiliate or successor, by either Party hereto, whether by operation of law or
otherwise, without the prior written consent of the other Party, which consent
may not be unreasonably withheld or delayed. No assignment of all or any portion
of the rights, interests or obligations permitted pursuant to the immediately
preceding sentence shall relieve or discharge the assignor from any of its
obligations under this Agreement without the prior written consent of the
non-assigning Party, which consent shall not be unreasonably withheld or
delayed. Any assignment of this Agreement in violation of the foregoing shall
be, at the option of the non-assigning Party, void.

(i) Purchaser may assign all or any portion of its rights and obligations
hereunder to any of its Affiliates, (ii) Independence may assign all or any
portion of its rights and obligations hereunder to any of its Affiliates

institution for the purposes of financing or refinancing any of its assets,
including upon or pursuant to the exercise of remedies with respect to such
financing or refinancing, or by way of assignments, transfers, pledges or other
dispositions in lieu thereof, provided, however, that no such assignment of all
or any portion of the rights, interests or obligations of a party pursuant to
this Section 21.01(b) shall relieve or discharge the assignor from any of its
obligations under this Agreement unless the non-assigning Party consents to such
release or discharge in accordance with Section 21.01(a). With respect to clause
(iii) of this Section 21.01(b), Purchaser agrees to execute and deliver such
documents as may be reasonably necessary to accomplish any such assignment,
transfer, pledge or other disposition of rights hereunder, so long as
Purchaser's rights under this Agreement are not thereby altered, amended,
diminished or otherwise impaired.

                          ARTICLE XXII - FORCE MAJEURE

      22.01 FORCE MAJEURE

            (a) The term "Force Majeure" shall mean causes beyond the reasonable

<Page>

disturbances; earthquakes; storms; fires; lightning; epidemics; wars; riots or
civil disturbances; sabotage or condemnation or other similar acts.
Notwithstanding the foregoing, under no circumstances shall Force Majeure
include any of the following: (i) any reduction, curtailment or interruption of

reduction, curtailment or interruption is caused by or arises from the
negligence or willful misconduct of the affected Party or any third party vendor
or supplier to the Facility of materials, equipment, supplies or services; (ii)
changes in market conditions that affect the cost of or demand for Energy,
Ancillary Services or Gas; (iii) any NYISO or other grid constraint affecting
the transmission of energy by Purchaser from the Electric Delivery Point; (iv)
derating of the Facility, unless such derating is due to a Force Majeure event;
(v) change in Law; (vi) failure of a Party to obtain and maintain any
governmental approval, (vii) any failure or Outage of the Facility the cause of
which cannot be determined through reasonable diligence; (viii) any failure or
outage of the Facility that is due to a latent or patent defect or inadequacy in
the generation equipment comprising the Facility; (ix) any failure or outage of
the Facility that is due to the improper or negligent maintenance, installation,
delivery, or design of the Facility; (x) the unavailability of equipment, goods,
or services that could have been avoided by the observance of Good Electrical
Practices or (ix) causes or events affecting the performance of third-party
suppliers of goods or services to the Facility or to Independence except to the
extent caused by an event that otherwise is an event of Force Majeure as

            (b) If either Party because of Force Majeure is rendered wholly or
partly unable to perform its obligations under this Agreement, except for a
Party's obligation to make payments under this Agreement (which shall not be
excused), that Party shall be excused from whatever performance is affected by
the Force Majeure to the extent so affected, provided that the Party whose
performance under this Agreement is affected by an event of Force Majeure (i)
gives the other Party notice of the occurrence of such Force Majeure event as
soon as possible, and (ii) uses all commercially reasonable efforts to remedy
the cause(s) and effect(s) of such Force Majeure event with all reasonable
dispatch. If an event of Force Majeure results in an Outage of the Facility,
Independence shall use commercially reasonable efforts to remedy the cause(s)
and effect(s) of such Force Majeure event with all reasonable dispatch,
including, if necessary, the reconstruction, repair or replacement of all or a
portion of the Facility utilizing the proceeds of insurance required pursuant to

      23.01 TAXES - POWER

            (a) Purchaser is liable for and shall pay, cause to be paid,

Authority, or to any other entity, all Taxes arising out of or related to
Independence's performance in providing Tolling Services or Ancillary Services
under this Agreement including (i) any Taxes imposed or collected by a taxing
authority with jurisdiction over Purchaser, and (ii) any Taxes imposed on the
delivery or sale of Energy or Ancillary Services to Purchaser, or Purchaser's
possession, transportation, consumption, use, sale or other disposition of the
Energy or Ancillary Services; provided, however, that Purchaser shall not be
responsible for the payment of any Taxes levied on or with respect to
Independence's personal or real property.

            (b) Each Party will provide the other Party upon written request a
certificate of exemption or other reasonably satisfactory evidence of exemption
if any exemption from or reduction of any Tax is applicable. Each Party will
exercise commercially reasonable efforts to obtain and to cooperate in obtaining
any exemption from or reduction of any Tax.

      23.02 TAXES - GAS

            (a) Purchaser is liable for and shall pay, or cause to be paid, or
reimburse Independence if Independence has paid, all Taxes applicable to Gas
provided by Purchaser pursuant to Section 8.01(a) this Agreement including (i)

sold hereunder, but excluding all Taxes applicable to the Gas sold hereunder
downstream of the Gas Facility Point and except in each case to the extent that
the Tax is assessed due to any subsequent sale by Independence of such Gas. All
Taxes incurred in or attributable to the production, sale, and delivery,
handling, or transportation of the Gas sold and delivered pursuant to Section
8.01(b) of this Agreement (or otherwise caused by or attributable to such Gas)

a result of the transfer of title to the Gas sold hereunder) shall be the
responsibility of Purchaser and Purchaser shall indemnify, defend, and hold
Independence and its officers, directors, employees, agents, and partners
harmless from and against all such Taxes. Any liability for the New York State
Tax on Natural Gas Importers under ss.189 of the New York Tax Law, or any

Purchaser shall indemnify, defend, and hold Independence and its officers,
directors, employees, agents, and partners harmless from and against all such
Taxes. Except as provided in the Gas Supply Agreement and with respect to Sec.
189 Taxes, all Taxes incurred in or attributable to the purchase and transfer,
handling, or transportation of the Gas purchased and received pursuant to
Section 8.01(b) of this Agreement (or otherwise caused by or attributable to
such Gas) after the Gas Facility Point shall be the responsibility of
Independence, and Independence shall indemnify, defend, and hold Purchaser and
its officers, directors, employees, agents, and shareholders harmless from and
against all such Taxes. Except as provided in the Gas Supply Agreement, all
sales, transfer, and use Taxes (if any) applicable to the sale or transfer of
Gas pursuant to Section 8.01(b) of this Agreement at the Gas Facility Point
shall be borne 50% each by Independence and Purchaser. Each of Purchaser and
Independence shall apply for, and shall cooperate with the other in applying
for, such exemption and other certificates as the other reasonably may request
to eliminate the necessity of paying, collecting, or withholding any such Taxes.

      23.03 COOPERATION

      The Parties agree to use commercially reasonable efforts to mitigate the
Parties' exposure to Taxes which could be imposed on either Party as a result of

      24.08 CONFIDENTIALITY

            (a) "Confidential Information" shall be any information or data
exchanged by the Parties relating to the trading and marketing activities of
either Party, the bids and Schedules submitted directly or indirectly to the
NYISO pursuant to this Agreement or daily advisory billing statements and
monthly billing statements received from the NYISO related to the Facility
(including non-public information related thereto communicated to a Party from
the NYISO). Confidential Information shall not include information:

                  (i) which was developed by the Receiving Party and was
contained in a writing in the Receiving Party's possession before its receipt
from the other Party;

                  (ii) which at the time of its disclosure to the Receiving
Party is, or thereafter becomes, through no act or failure to act on the part of
the Receiving Party, part of the public domain;

                  (iii) which has been rightfully furnished to the Receiving
Party by a third party without restriction on disclosure or use and not in
violation of any rights of, or obligations to, the other Party.

      The occurrence of any of the above exceptions shall not be construed as an
express or implied grant of any rights under any of the other Party's patents or
other intellectual property rights. For the purposes of this Section 24.08, a
Party that receives Confidential Information from the other Party shall be
referred to as the "Receiving Party."

                     ***CONFIDENTIAL TREATMENT REQUESTED***

                                       55
<Page>

            (b) No Receiving Party shall disclose or use Confidential
Information received from the other Party for any purpose other than in
connection with the performance of its obligations under this Agreement, without
the prior written consent of the other Party. The Receiving Party agrees to
utilize with respect to received Confidential Information the same standards and
procedures which it applies to protection of its own confidential information,
but not less than reasonable care.

            (c) Each Party will limit access to received Confidential
Information to those of its owners, affiliates, directors, officers, employees,
attorneys, lenders, contractors, suppliers, agents, and consultants who need to
know about or participate in the performance of its obligations under this
Agreement. Each Party agrees to (i) inform each of its owners, affiliates,
directors, officers, employees, attorneys, lenders, contractors, suppliers,
agents, and consultants who receive Confidential Information of the confidential
nature thereof and of the obligations imposed by this Agreement, and (ii) each
Party shall remain primarily liable to the other for unauthorized use or
disclosure of received Confidential Information by its owners, affiliates,
directors, officers, employees, attorneys, lenders, contractors, suppliers,
agents or consultants receiving such information.

            (d) Notwithstanding Section 24.08(c), Independence shall not
disclose Confidential Information to individuals who are actively involved in
material marketing and trading activities in the markets administered by the
NYISO; provided that Independence may designate by notice to Purchaser up to two
individuals for receipt of Confidential Information who have responsibilities
related to the Facility and associated contracts (including this Agreement) and
who are engaged in material marketing and trading activities in the markets
administered by the NYISO; provided further that Independence shall take all
reasonable precautions to ensure that such designated individuals do not utilize
Confidential Information in their marketing and trading activities; and provided
further that information related to transmission congestion contracts or
Installed Capacity contained in daily advisory billing statements and monthly
billing statements received from the NYISO related to the Facility shall not be
considered Confidential Information for purposes of this Section 24.08(d) only.
Such individuals will not be provided access to the results of the NYISO's
Day-Ahead Market bidding process undertaken by Purchaser under this Agreement
and the Energy Management Agreement, unless and until Independence's Facility
operating personnel (who will have daily access to such results) (i) have
identified a problem or material issue regarding such results, (ii) have
attempted to discuss the problem or material issue with Purchaser, and (iii)
following such discussions, have been unable to resolve the problem or material
issue.

            (e) Notwithstanding Section 24.08(c), Purchaser shall not disclose
information related to transmission congestion contracts or Installed Capacity

                     ***CONFIDENTIAL TREATMENT REQUESTED***

                                       56

contained in daily advisory billing statements and monthly billing statements
received from the NYISO related to the Facility to individuals who are actively
involved in material marketing and trading activities in the markets
administered by the NYISO.

            (f) Each Party may disclose Confidential Information to third
parties or other Governmental Authorities, including NYISO, to the extent such
disclosures are contemplated in and required by the Parties in connection with
the performance of their obligations under this Agreement. Each Party may also
disclose Confidential Information which it is legally required to furnish to
comply with a subpoena or other legal process of a Governmental Authority,
provided that the disclosing Party shall use reasonable efforts to limit such
disclosure and to obtain confidential treatment of such Confidential
Information.

            (g) The provisions of this Section 24.08 shall survive expiration,
cancellation, or termination of this Agreement. Each Party agrees to be bound by
the confidentiality obligations herein for a period of five (5) years from
expiration, cancellation or termination.

      24.09 COUNTERPARTS

      This Agreement may be executed in counterparts, all of which shall
constitute one and the same Agreement and each of which shall be deemed to be an
original.

      24.10 NO OFFSET

      Except as provided in Section 12.05, the amounts due Purchaser from
Independence and the amounts due Independence from Purchaser shall constitute
separate and independent obligations and may not be offset or net against each
other or offset or net against any other amounts due between the Parties
(whether under this Agreement or otherwise).

      24.11 OTHER ACTIVITIES

      The Parties acknowledge and agree that either Party or its Affiliates may
engage in competitive activities, including, on the part of Independence and its
Affiliates, the possible expansion of the Facility or construction of a new
generating facility adjacent to the Facility; provided, however, that such
activities shall not interfere with the Party's ability to perform its
obligations under this Agreement.

Monday and Tuesday in this example). The Parties shall comply with the
communications deadlines set forth in the table. Note that pursuant to Section
10.01(a), Independence shall initially be responsible for the submission of all
NYISO Bids. Pursuant to Section 10.01(b), at some point during the Contract
Term, Purchaser may take over responsibility to submit the NYISO Bids. The Daily
Operating Procedures set forth in this Exhibit 5.02(A)(I) describe a process
pursuant to which Purchaser submits all NYISO Bids. Until Purchaser takes over
responsibility to submit all NYISO Bids, the Parties will work together to
effectuate the requirements of this Exhibit 5.02(A)(I) with Independence
submitting all NYISO Bids.

Operating activities pursuant to this Exhibit 5.02(A) shall not result in any
operations of the Facility that conflict with the requirements of Exhibit

                                    Independence notifies Purchaser under Step 5 that it will require Gas to
                                    operate at the Minimum Output Requirement in the HAM, Purchaser shall submit
                                    HAM bids to ensure that the NYISO Directed Operation will be at least equal
                                    to the Minimum Output Requirement.  If under this Case 2,  Purchaser

[NOTES:

o     This form may be modified only with the concurrence of the NYISO.

o     Independence's ability to provide 10-minute spinning reserve service and
      30-minute spinning reserve service is currently contingent upon resolution
      with the NYISO of modified procedures for applicable ramp rates.

o     At present, Independence is bid into the NYISO as a single PURPA facility.
      In addition, the power supplied to Alcan, as measured by a Niagara Mohawk
      revenue meter, is subtracted from the net generation of Independence, as
      measured by two Niagara Mohawk revenue meters, to determine and measure
      the net output of the Facility to the grid (i.e., to the NYISO and Niagara
      Mohawk). As a single PURPA facility, in general, the amount of energy that
      the Facility actually produces that is above or below the NYISO Directed
      Operation level "floats" under the Niagara Mohawk Power Purchase Agreement
      between 0 MWs and a maximum of 300 MWs. If the Facility is not selected in
      the DAM and it runs in the HAM, under the Niagara Mohawk Power Purchase
      Agreement, Niagara Mohawk must purchase up to 300 MWs. As a result, the
      Facility's participation in the HAM is currently limited to sales under
      the

                     ***CONFIDENTIAL TREATMENT REQUESTED***

                                       70

      Niagara Mohawk Power Purchase Agreement of up to 300 MWs. Independence
      is working with the NYISO with respect to this issue.

o     Independence physically has two revenue meters, one for each power block,
      which are summed for net generation. Independence has commenced initial
      discussions with the NYISO and Niagara Mohawk on "splitting" into two
      separate "generators" in the eyes of the NYISO. Issues that need to be
      resolved are changes in software with Niagara Mohawk and NYISO,
      modifications to provide proper basepoint signals, how to handle PURPA
      "float" with Niagara Mohawk and how to deal with Alcan load. As for
      Purchaser, even if two "generators" to the ISO, Independence would still
      be considered a single Facility for power output, heat rate, etc. This
      "splitting" would provide much greater flexibility in how to bid
      Independence with the ISO.

o     There are certain constraints or limitations on how the Facility can be
      bid into the NYISO market and also meet the Agreement restrictions in
      number of starts per day, time between starts and startup times, etc.
      Details will have to be developed between Independence and Purchaser;
      however, as examples:

o     assuming availability of the entire Facility (i.e. all gas and steam
      turbines available), Independence could bid a minimum generation of
      nominal 500 MWs with defined startup cost for 4 GTs and run with various
      combinations thereafter.

o     assuming the availability of the entire Facility, if Independence or
      Purchaser wanted to specify minimum generation and startup cost, etc. with
      a single GT, then Independence does not believe it is possible to use the
      cost curve format for bidding up to 1000 MWs.

o     assuming availability of the entire Facility, if one bid using the block
      method of 250, 500 and 1000 blocks, then the minimum generation of 250
      reflect that 2 GTs must be operating and the startup costs should reflect
      the startup of 2 GTs. Then the cost of starting 1 GT for the 500 MW block
      would have to be incorporated in this block and likewise for the 1000 MW
      block. Once we see the actual dispatch scenario, since we can operate up
      to nominal 500 MWs with 2 GTs or operate down to 500 MWs with 4 GTs, the
      determination of how to actually operate can be determined.]

EXHIBIT 5.03

SHUTDOWN

For a Scheduled Shutdown, Independence requires 30 minutes to complete the
Shutdown. Shutdown Gas is equal to 600 MMBtu per combustion turbine. The Energy
output during Shutdown varies depending on the load level prior to Shutdown, but
with a baseload facility running at 1000 MW, a 30 minute shutdown would produce
approximately 250 MWh of Energy. For purposes of this Agreement, the term
"Shutdown Gas" refers to the amounts described in this Exhibit.

EXHIBIT 6.01

GUARANTEED HEAT RATE

The Guaranteed Heat Rate, measured in Btu/kWh (HHV) for the Tolling Services
provided to Purchaser is equal to the levels set forth in Table 6.01 below.

The Guaranteed Heat Rate for load factors between 100% and 80% assumes four
combustion turbine/generator sets operating combined cycle mode. The Guaranteed
Heat Rate for load factors between 75% and 55% assumes three combustion
turbine/generator sets operating in combined cycle mode. The Guaranteed Heat
Rate for load factors between 50% and 30% assumes two combustion
turbine/generator sets operating in combined cycle mode. The Guaranteed Heat
Rate for load factors between 25% and 15% assumes one combustion
turbine/generator set operating in combined cycle mode.

For clarification, if Purchaser desires operations at a load factor between 100%
and 15% but not in accordance with the number of combustion turbine/generator
sets as stated above (but still within the operating parameters of the plant),
the Guaranteed Heat Rate shall be as set forth in Table 6.01 below for the load
factor equal to the desired plant load factor divided by the number of
combustion turbine/generator sets Purchaser desires to operate. For example, if
Purchaser desires operating at a plant load factor of 60% but with four
combustion turbine/generator sets, the Guaranteed Heat Rate shall be that set
forth for such month at a 15% load factor.

Collateral Agent when the Company delivers a notice of default to the
Partnership under the Assigned Contract. The Collateral Agent shall have the
right (but not the obligation) to cure the defaults listed in any Notice within
the same period of time provided in the Assigned Contract for the Partnership to
cure such default; PROVIDED, HOWEVER, if the nature of any non-monetary default
on the part of the Partnership under the Assigned Contract is such that it
cannot be cured by the Collateral Agent without the Collateral Agent having
taken possession of the Project (as defined in the Security Agreement), then the
Collateral Agent's time for commencing such cure shall be extended for such
reasonable period of time as is necessary for the Collateral Agent to lawfully
obtain possession of the Project; PROVIDED, FURTHER, that the Collateral Agent
shall at all times be seeking by all reasonable and lawful means to obtain such
possession. Once the defaults listed in any Notice are timely cured by the
Collateral Agent, there shall no longer be deemed to be any default

                     ***CONFIDENTIAL TREATMENT REQUESTED***

                                     - 82 -

under the Assigned Contract in respect of such defaults so cured. The curing of
any defaults under the Assigned Contract shall not in and of itself be construed
as an assumption by the Collateral Agent or any of the Secured Parties of any of
the obligations, covenants or agreements of the Partnership under the Assigned
Contract.

            (b) If a notice of election is delivered to the Company as provided
in Section 5 below, the Company will accept performance of the Partnership's
obligations (as specified in such notice of election) under the Assigned
Contracts by the Collateral Agent, or its nominee(s) acting for the Secured
Parties, as the case may be, in lieu of the Partnership's performance of such
obligations.

            (c) Upon any transfer of the Partnership's rights under the Assigned
Contract pursuant to the exercise of the Collateral Agent's rights under this
Consent, the Collateral Agent or any third party to which such rights are
transferred by the Collateral Agent (hereinafter, a "THIRD PARTY TRANSFEREE")
shall, upon the Company's reasonable satisfaction with the Collateral Agent's or
such Third Party Transferee's financial condition and subject to all applicable
laws, rules and regulations, succeed to all of the Partnership's right, title
and interest under and in connection with the Assigned Contract and shall be
obligated to perform all of the terms and conditions of the Assigned Contract,
except that the Collateral Agent or any Third Party Transferee shall not be
required to perform or cause to be performed any of the Partnership's
obligations under the Assigned Contract (except for the Partnership's obligation
for the payment of all amounts due and payable to the Company under the terms of
the Assigned Contract including any interest applicable thereon) that remain
unperformed at the time that the Collateral Agent or such Third Party Transferee
is transferred such Assigned Contract other than continuing non-monetary
defaults under the Assigned Contract which are capable of performance by the
Collateral Agent or the Third Party Transferee or be liable for any prior act or
omission of the Partnership, and upon the transfer by the Collateral Agent of
its rights and interests and the rights and interests of the Partnership under
the Assigned Contracts to a Third Party Transferee, the Collateral Agent and the
Partnership shall be relieved of all obligations under the Assigned Contract
arising after such transfer.

            (d) In the event that (i) the Assigned Contract is rejected by a
trustee or any person exercising the powers of a trustee in any bankruptcy or
insolvency proceeding applicable to the Partnership or (ii) the Assigned
Contract is terminated as a result of any bankruptcy or insolvency proceeding
applicable to the Partnership, the Company shall, subject to all applicable
laws, rules and regulations, execute and deliver to the Collateral Agent and its
designees, successors and assigns a new contract; PROVIDED that the Company
shall be required to execute a new contract with the Collateral Agent only if
the Collateral Agent or its designees, successors or assigns shall within ten
(10) business days of entering

                     ***CONFIDENTIAL TREATMENT REQUESTED***

                                     - 83 -
<Page>

into such new contract, cure all defaults for failure to pay all amounts due and
payable to the Company under the Assigned Contract, including any interest
applicable thereon. The new contract shall, subject to all applicable laws,
rules and regulations, contain the same covenants, agreements, terms, provisions
and limitations as the Assigned Contract (except for any requirements with
respect to past performance which have been fulfilled by the Partnership or the
Collateral Agent or its designees, successors and assigns hereunder).

      SECTION 5. LIABILITY OF SECURED PARTIES

      The Collateral Agent, on behalf of the Secured Parties, and its successors
and assigns, shall have no right or power to enforce the Assigned Contract, and
assumes no duty or obligation thereunder unless and until the Collateral Agent
shall have notified the Company that it has elected to exercise its rights and
remedies under the Security Agreement and to substitute itself in the position
of the Partnership under the Assigned Contracts and has agreed in a written
instrument executed by the Collateral Agent to be bound by all terms and
conditions of the Assigned Contract applicable to the Partnership.

      SECTION 6. FURTHER ASSURANCES

      The Company hereby agrees to execute and deliver all such instruments and
take all such actions as may be reasonably necessary to effectuate fully the
purposes of this Consent, provided, however, that such further assurances shall
not expand the liability, or obligations arising under this Consent or dilute
any rights or remedies otherwise accruing to Company under this Consent.

      SECTION 7. NOTICES

      All notices and other communications hereunder shall be in writing, shall
refer on their face to the Assigned Contract (although failure to so refer shall
not render any such notice or communication ineffective), shall be sent by first
class mail, facsimile, by hand or overnight courier service and shall be
directed:

            (a)   if to the Company, in accordance with the Assigned Contract;

and

            (d) to such other address as any party may designate by notice to
the other party hereto given pursuant hereto.

      SECTION 8. MISCELLANEOUS

      (a) GOVERNING LAW. This Consent shall be governed by and construed in
accordance with the law of the State of New York as to all matters (without
giving effect to conflict of law principles). Each of the Company and the
Partnership hereby irrevocably waives, to the fullest extent permitted by law,
any and all right to trial by jury in any legal proceedings arising out of or
relating to this Consent.

      (b) SUBMISSION TO JURISDICTION. Each of the Parties hereby irrevocably and
unconditionally:

                  (i) submits for itself and its property in any legal action or
proceeding relating to this Consent, or for recognition and enforcement of any
judgment in respect thereof, to the non-exclusive general jurisdiction of the
Courts of the State of New York, the courts of the United States for the
Southern District of New York and appellate courts from any thereof;

                  (ii) agrees that service of process in any such action or
proceeding may be effected by mailing a copy thereof by registered or certified
mail (or any substantially similar form of mail), postage prepaid, to the other
Party at its address set forth in Section 7, or at such other address of which
the other Party shall have been notified pursuant thereto; and

                  (iii) agrees that nothing herein shall affect the right to
effect service of process in any other manner permitted by law.

      (c) HEADINGS. The descriptive headings of the Articles and Sections of
this Consent are inserted for convenience only and are not intended to affect
the meaning, interpretation or construction of this Consent.

      (d) WAIVER. Except as otherwise provided in this Consent, any failure of a
party to comply with any obligation, covenant, agreement or condition herein may
be waived by the party entitled to the benefits thereof only by a written
instrument signed by the party granting such waiver, but such waiver shall not
operate as a waiver of, or estoppel with respect to, any subsequent failure of
the first party to comply with such obligation, covenant, agreement or
condition.

      (e) SEVERABILITY. Any provision of this Consent which is prohibited or
unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective
to the extent of such prohibition or unenforceability without invalidating the

jurisdiction shall not invalidate or render unenforceable such provision in any
other jurisdiction.

to the benefit of the Company, the Collateral Agent, the Partnership and their
respective permitted successors and assigns.

      (g) COUNTERPARTS. This Consent may be executed in counterparts, all of

EXHIBIT 17.01(B)

EXHIBIT B

                               GUARANTY AGREEMENT

      Base Guaranty Agreement (this "Guaranty") dated as of July 1, 2001 is made
and entered into by Dynegy Holdings Inc., a Delaware corporation ("Guarantor"),
to and for the benefit of Sithe/Independence Power Partners, L.P., a Delaware
limited partnership ("Independence"), and its successors and permitted assigns.

                                   WITNESSETH:

      WHEREAS, Independence and Dynegy Power Marketing, Inc., a Texas
corporation (together with successors and permitted assigns, "Purchaser"), have
entered into a TOLLING AGREEMENT dated as of July 1, 2001 (as amended,
supplemented or modified from time to time, the "Tolling Agreement"), a copy of
which is attached hereto as Exhibit 1;

      WHEREAS, Purchaser is an indirect, wholly owned subsidiary of Guarantor,
and Guarantor will derive substantial benefit from the performance by
Independence of its obligations under the Tolling Agreement;

      WHEREAS, it is a condition precedent to Independence's obligations under
the Tolling Agreement that this Guaranty be duly executed and delivered to
Independence; and

      WHEREAS, Guarantor is willing to enter into this Guaranty.

      NOW, THEREFORE, in consideration of the foregoing premises and the
representations, warranties, covenants and agreements contained herein, and for
other good and valuable consideration, the receipt and adequacy of which are
hereby acknowledged, and intending to be legally bound, Guarantor hereby
covenants and agrees as follows:

      1. GUARANTY. Subject to the terms hereof, Guarantor hereby irrevocably,
absolutely, and unconditionally guarantees to Independence and its successors
and permitted assigns the due, punctual and full performance and payment of each
and every obligation of Purchaser under the Tolling Agreement (each such
obligation hereinafter referred to, individually, as a "Guaranteed Obligation"
and, collectively, as the "GUARANTEED OBLIGATIONS") and agrees that, if for any
reason whatsoever Purchaser shall fail or be unable duly, punctually and fully
to perform or pay any such Guaranteed Obligation, Guarantor shall forthwith,
upon demand as provided

                     ***CONFIDENTIAL TREATMENT REQUESTED***

                                     - 88 -
<Page>

in Section 4 hereof, perform or pay such Guaranteed Obligation, or cause such
Guaranteed Obligation to be performed or paid, without regard to any exercise or
nonexercise by Independence, its successors or permitted assigns of any right,
power or privilege under or in respect of the Tolling Agreement or the
Guaranteed Obligations. In connection with the foregoing, Independence
acknowledges that performance of the obligations of Purchaser under the Tolling
Agreement, to the extent that such performance is for an obligation other than
the payment of money, shall be accomplished by Guarantor causing such
performance to occur through a third party or otherwise by the payment of money.
This Guaranty shall be direct, immediate and primary and shall be a guaranty of
performance and payment and not of collection, and is not conditioned or
contingent upon any attempt to collect from Purchaser or upon any other event,
contingency or circumstance whatsoever, except as expressly provided otherwise
herein.

      2. OBLIGATIONS UNCONDITIONAL. Guarantor covenants to and agrees with
Independence and its successors and permitted assigns that, to the fullest
extent permitted by law, its obligations under this Guaranty are irrevocable,
absolute and unconditional, shall remain in full force and effect, and shall not
be impaired or affected by, or be subject to, any reduction, termination or
other impairment by set-off, deduction, counterclaim, recoupment, interruption
or otherwise, and Guarantor shall have no right to terminate this Guaranty or to
be released, relieved or discharged, in whole or in part, from its performance
or payment obligations referred to in this Guaranty for any reason whatsoever
(other than the performance and payment in full of the Guaranteed Obligations),
including (a) any amendment, supplement or modification to, waiver of, consent
to or departure from, or failure to exercise any right, remedy, power or
privilege under or in respect of, the Tolling Agreement, the Guaranteed
Obligations or any other agreement or instrument relating thereto, (b) any
insolvency, bankruptcy, reorganization, dissolution or liquidation of, or any
similar occurrence with respect to, or cessation of existence of, or change of
ownership of Purchaser, or any rejection of any of the Guaranteed Obligations in
connection with any Proceeding (as defined in Section 3 below) or any
disallowance of all or any portion of any claim by Independence, its successors
or permitted assigns in connection with any Proceeding, (c) any lack of
genuineness, legality, validity, regularity, enforceability or value of the
Tolling Agreement, any of the Guaranteed Obligations, or any other agreement or
instrument relating thereto, (d) the failure to create, preserve, validate,
perfect or protect any security interest granted to, or in favor of, any person,
(e) any substitution, modification, exchange, release, settlement or compromise
of any security or collateral for or guaranty of any of the Guaranteed
Obligations or failure to apply such security or collateral or failure to
enforce such guaranty or (f) any other event or circumstance whatsoever that
might otherwise constitute a legal or equitable discharge of a surety or
guarantor (other than the payment in full of the Guaranteed Obligations, and
defenses available to Purchaser

                     ***CONFIDENTIAL TREATMENT REQUESTED***

                                     - 89 -
<Page>

under the Tolling Agreement), it being the intent of Guarantor that its
obligations under this Guaranty shall be irrevocable, unconditional and absolute
under any and all circumstances, except as expressly provided herein. This
Guaranty and the obligations of Guarantor hereunder shall continue to be
effective or be automatically reinstated, as the case may be, if at any time any
payment by or on behalf of Purchaser is rescinded or must otherwise be restored
by Independence, its successors or permitted assigns for any reason, including,
but not limited to, as a result of any Proceeding with respect to Purchaser or
any other person, as though such payment had not been made.

      3. INTEREST. The Guaranteed Obligations shall include, without limitation,
interest accruing as part of the Guaranteed Obligations by the terms thereof
following the commencement by or against Purchaser of any case or proceeding
under any law relating to bankruptcy, insolvency, reorganization, winding-up,
liquidation, dissolution or composition or adjustment of debt (hereinafter, a
"PROCEEDING").

      4. DEMAND. If Purchaser shall fail or be unable duly, punctually and fully
to perform or pay any Guaranteed Obligation, Independence, its successors or
permitted assigns may at any time prior to the full performance or payment of
such Guaranteed Obligation deliver notice of such failure or inability of
Purchaser to perform or pay to Guarantor in writing, which notice shall
reasonably specify the nature of such failure or inability to perform or pay, as
the case may be and, in the case of a failure or inability to pay, the amount
thereof (each such written notice hereinafter a "DEMAND"). Guarantor shall, upon
receipt of a Demand, forthwith perform or pay such Guaranteed Obligation, or
cause such Guaranteed Obligation to be performed or paid in full. Promptly on
request, Guarantor shall reimburse Independence, its successors and permitted
assigns for all costs and expenses (including reasonable attorneys' fees)
incurred in enforcing Independence's, its successors' or permitted assigns'
rights under this Guaranty, but only to the extent that Independence is
successful in enforcing Independence's rights under this Guaranty.

      5. REPRESENTATIONS AND WARRANTIES. Guarantor represents and warrants to
Independence and its successors and permitted assigns that as of the date
hereof:

                  (a) it is a corporation duly organized, validly existing and
            in good standing under the laws of the State of Delaware, it has the
            corporate power and authority to execute, deliver and carry out the
            terms and provisions of this Guaranty;

                  (b) no authorization, approval, consent or order of, or
            registration or filing with, any court or other governmental body

                     ***CONFIDENTIAL TREATMENT REQUESTED***

                                     - 90 -
<Page>

            having jurisdiction over Guarantor is required on the part of
            Guarantor for the execution and delivery of this Guaranty;

                  (c) this Guaranty has been duly executed and delivered by
            Guarantor and constitutes a valid and legally binding agreement of
            Guarantor enforceable against Guarantor in accordance with its
            terms, subject, however, to applicable bankruptcy, insolvency,
            reorganization, moratorium or similar laws affecting creditors'
            rights generally and except as the enforceability thereof may be
            limited by general principles of equity (regardless of whether
            considered in a proceeding in equity or at law);

                  (d) the execution, delivery and performance of this Guaranty
            have been duly authorized by all necessary corporate action and do
            not require any other actions or proceedings or any stockholder
            approval or consent of any trustee or holder of any indebtedness of
            Guarantor;

                  (e) the execution, delivery and performance of this Guaranty
            and compliance by Guarantor with the terms hereof (i) will not
            violate any governmental approval or law applicable to it or any of
            its property, (ii) will not violate any provision of its certificate
            of incorporation, bylaws or other governing documents, and (iii)
            will not violate or constitute a default under any agreement or
            instrument to which it is a party or by which it or any of its
            property may be bound, or result in the creation or imposition of
            any lien upon any of its property, which violation, default or lien
            would have a material adverse effect on its ability to perform its
            obligations under this Guaranty;

                  (f) except as disclosed in Guarantor's latest Form 10-K and
            any Form 10-Qs or Form 8-Ks subsequently filed with the Securities
            and Exchange Commission, there are no actions, suits, investigations
            or proceedings against Guarantor by or before any court, arbitrator,
            administrative or regulatory agency, or other governmental authority
            pending, or to its knowledge, threatened against or affecting it,
            its properties, or its assets that, if adversely determined, would
            reasonably be expected to have a material and adverse effect on its
            ability to perform its obligations under this Guaranty; and

                  (g) it directly or indirectly owns all of the issued and
            outstanding shares of each class of capital stock of Purchaser.

      6. DOWNGRADE EVENT. If at any time any two of the credit ratings then
assigned to Guarantor's unsecured, senior long-term debt obligations falls below

                     ***CONFIDENTIAL TREATMENT REQUESTED***

                                     - 91 -
<Page>

"Investment Grade" from the Standard & Poor's Rating Group (a division of
McGraw-Hill, Inc.) or its successor ("S&P"),"Investment Grade" from Moody's
Investor Services, Inc. or its successor ("MOODY'S") or "Investment Grade" from
Fitch IBCA, Inc. or its successor ("FITCH") (or if Guarantor is not rated by any
of S&P, Moody's or Fitch), then Independence may require Guarantor to provide
collateral in the form of either a substitute guaranty on terms and conditions
substantially similar to this Guaranty (from a substitute guarantor whose
unsecured, senior long-term debt obligations are rated at least "Investment
Grade" from two of S&P, Moody's and Fitch) or other security reasonably
acceptable to Independence and Purchaser ("Performance Assurance") in an amount
determined by Independence in a commercially reasonable manner. The failure of
Guarantor to provide such Performance Assurance or a guaranty or other credit
assurance acceptable to Independence within twenty (20) business days of receipt
of notice shall constitute an Event of Default under the Tolling Agreement and
Independence will be entitled to the remedies set forth in the Tolling
Agreement.

      7. AMENDMENT OF GUARANTY. No term or provision of this Guaranty shall be
amended, modified, altered, waived, supplemented or terminated except in a
writing signed by Guarantor and Independence or Independence's successors and
permitted assigns.

      8. WAIVERS. To the fullest extent permitted by law, and except for the
Demand required pursuant to Section 4 hereof, Guarantor hereby waives (a) all
set-offs, counterclaims, presentments, demands for performance, notices of
nonperformance, protests, notice of any of the matters referred to in Section 2,
notices of protests, notices of dishonor, notice of any waivers or indulgences
or extensions, and notices of every kind that may be required to be given by any
statute or rule of law and notice of acceptance of this Guaranty, (b) diligence,
presentment, and demand of payment, filing of claims with a court in connection
with any Proceeding, protest or notice with respect to the Guaranteed
Obligations and all demands whatsoever; and (c) any requirement that any action
or proceeding be brought against Purchaser or any other person, or any
requirement that any person exhaust any right, power or remedy or proceed
against any other person, prior to any action against Guarantor under the terms
hereof. No delay on the part of Independence, its successors or permitted
assigns in the exercise of, or failure to exercise, any right or remedy shall
operate as a waiver thereof, a waiver of any other rights or remedies, or a
release of Guarantor from any obligations hereunder, and no single or partial
exercise by Independence, its successors or permitted assigns of any right or
remedy shall preclude any further exercise thereof or the exercise of any other
right or remedy.

      9. WAIVER OF SUBROGATION. Guarantor hereby agrees that it will not
exercise, and hereby irrevocably, absolutely and unconditionally waives, any
rights of subrogation, contribution, reimbursement, indemnification or other
rights of

                     ***CONFIDENTIAL TREATMENT REQUESTED***

payment or recovery for any payments made by it hereunder until all
Guaranteed Obligations have been fully paid and performed.

      10. NOTICE. Any Demand, notice, request, instruction, correspondence or
other document to be given hereunder (herein collectively called "Notice") shall
be in writing and delivered personally or mailed by certified mail, postage
prepaid and return receipt requested, or by telecopy, as follows:

EXHIBIT 2

                           ACKNOWLEDGMENT AND CONSENT

      Acknowledgment and Consent (this "CONSENT") dated as of July 1, 2001
between Dynegy Holdings Inc. a Texas corporation (together with its successors
and assigns, the "COMPANY") and Sithe/Independence Power Partners, L.P., a
Delaware limited partnership (together with its successors and assigns, the
"PARTNERSHIP"), to and for the benefit of Manufacturers and Traders Trust
Company, a New York banking corporation, in its capacity as collateral agent
(together with successors and assigns in that capacity, the "COLLATERAL AGENT").

      SECTION 1. CONSENT TO ASSIGNMENTS, ETC.

      The Company hereby (a) acknowledges that it has been advised of that
certain Security Agreement and Assignment of Contracts dated as of January 1,
1993 (as amended, supplemented or modified and in effect from time to time, the
"SECURITY AGREEMENT") between the Collateral Agent and the Partnership, (b)
consents, subject to the provisions of this Consent, to the collateral
assignment by the Partnership of the Guaranty Agreement dated as of July 1, 2001
between the Company and the Partnership (as amended, supplemented or modified
and in effect from time to time, the "ASSIGNED CONTRACT") as collateral for the
Partnership's obligations to the Secured Parties (as defined in the Security
Agreement), and any subsequent assignments by the Collateral Agent, on behalf of
the Secured Parties, (c) acknowledges the right of the Collateral Agent,
following an Event of Default (as defined in the Security Agreement) by the
Partnership, to make all demands, give all notices, take all actions and
exercise all rights of the Partnership under the Assigned Contract as the
Partnership could have taken absent the Event of Default, and (d) acknowledges
and agrees that the Collateral Agent succeeding to the rights and obligations of
the Partnership under the Assigned Contract shall not, in and of itself,
constitute or cause a default by the Partnership under the Assigned Contract.

      SECTION 2. PAYMENT OF ASSIGNED SUMS

      All payments (if any) to be made by the Company to the Partnership under
the Assigned Contract shall be made by wire transfer to the account specified in
Section 24.07 of the Assigned Contract.

      SECTION 3. REPRESENTATIONS OF COMPANY

            (a) The Company represents and warrants that as of the date hereof:

                     ***CONFIDENTIAL TREATMENT REQUESTED***

                                     - 97 -
<Page>

                  (i) AUTHORIZATION. The execution, delivery and performance by
the Company of this Consent has been duly authorized by all necessary action on
the part of the Company and does not require any approval or consent of any
shareholder of the Company or any holder (or any trustee for any holder) of any
indebtedness or other obligation of the Company, except as has been heretofore
obtained.

                  (ii) EXECUTION; DELIVERY; BINDING AGREEMENT. This Consent has
been duly executed and delivered on behalf of the Company by the appropriate
officers of the Company and constitutes the legal, valid and binding obligation
of the Company, enforceable against the Company in accordance with its terms,
subject to applicable bankruptcy, insolvency, moratorium and other similar laws
applicable to creditors' rights generally and except as the enforceability
thereof may be limited by general principles of equity (regardless of whether
considered in a proceeding in equity or at law).

                  (iii) NO DEFAULT OR AMENDMENT. As of the date hereof, neither
the Company nor, to the knowledge of the Company, the Partnership is in default
under the Assigned Contract. The Company has no existing claims, counterclaims,
offsets or defenses against the Partnership in respect of the Assigned Contract
except for routine claims for payment under the Assigned Contract.

      SECTION 4. RIGHTS OF SECURED PARTIES

      The Company agrees that, subject to the provisions of this Consent, the
Secured Parties shall have the following rights with respect to the Assigned
Contract:

            (a) Notwithstanding anything to the contrary contained in the
Assigned Contract, the Assigned Contract shall not be terminated or cancelled by
action of the Company and shall not be deemed abandoned or surrendered without
prior notice in writing to the Collateral Agent specifying the Partnership's
default (hereinafter called a "NOTICE"). Any such Notice shall contain a copy of
the notice of default sent to the Partnership and shall be delivered to the
Collateral Agent when the Company delivers a notice of default to the
Partnership under the Assigned Contract. The Collateral Agent shall have the
right (but not the obligation) to cure the defaults listed in any Notice within
the same period of time provided in the Assigned Contract for the Partnership to
cure such default; PROVIDED, HOWEVER, if the nature of any non-monetary default
on the part of the Partnership under the Assigned Contract is such that it
cannot be cured by the Collateral Agent without the Collateral Agent having
taken possession of the Project (as defined in the Security Agreement), then the
Collateral Agent's time for commencing such cure shall be extended for such
reasonable period of time as is necessary for the Collateral Agent to lawfully
obtain possession of the Project; PROVIDED, FURTHER, that

                     ***CONFIDENTIAL TREATMENT REQUESTED***

                                     - 98 -
<Page>

the Collateral Agent shall at all times be seeking by all reasonable and lawful
means to obtain such possession. Once the defaults listed in any Notice are
timely cured by the Collateral Agent, there shall no longer be deemed to be any
default under the Assigned Contract in respect of such defaults so cured. The
curing of any defaults under the Assigned Contract shall not in and of itself be
construed as an assumption by the Collateral Agent or any of the Secured Parties
of any of the obligations, covenants or agreements of the Partnership under the
Assigned Contract.

            (b) If a notice of election is delivered to the Company as provided
in Section 5 below, the Company will accept performance of the Partnership's
obligations (as specified in such notice of election) under the Assigned
Contracts by the Collateral Agent, or its nominee(s) acting for the Secured
Parties, as the case may be, in lieu of the Partnership's performance of such
obligations.

            (c) Upon any transfer of the Partnership's rights under the Assigned
Contract pursuant to the exercise of the Collateral Agent's rights under this
Consent, the Collateral Agent or any third party to which such rights are
transferred by the Collateral Agent (hereinafter, a "THIRD PARTY TRANSFEREE")
shall, upon the Company's reasonable satisfaction with the Collateral Agent's or
such Third Party Transferee's financial condition and subject to all applicable
laws, rules and regulations, succeed to all of the Partnership's right, title
and interest under and in connection with the Assigned Contract and shall be
obligated to perform all of the terms and conditions of the Assigned Contract,
except that the Collateral Agent or any Third Party Transferee shall not be
required to perform or cause to be performed any of the Partnership's
obligations under the Assigned Contract (except for the Partnership's obligation
for the payment of all amounts due and payable to the Company under the terms of
the Assigned Contract including any interest applicable thereon) that remain
unperformed at the time that the Collateral Agent or such Third Party Transferee
is transferred such Assigned Contract other than continuing non-monetary
defaults under the Assigned Contract which are capable of performance by the
Collateral Agent or the Third Party Transferee or be liable for any prior act or
omission of the Partnership, and upon the transfer by the Collateral Agent of
its rights and interests and the rights and interests of the Partnership under
the Assigned Contracts to a Third Party Transferee, the Collateral Agent and the
Partnership shall be relieved of all obligations under the Assigned Contract
arising after such transfer.

            (d) In the event that (i) the Assigned Contract is rejected by a
trustee or any person exercising the powers of a trustee in any bankruptcy or
insolvency proceeding applicable to the Partnership or (ii) the Assigned
Contract is terminated as a result of any bankruptcy or insolvency proceeding
applicable to the Partnership, the Company shall, subject to all applicable
laws, rules and regulations, execute and deliver to the Collateral Agent and its
designees,
                     ***CONFIDENTIAL TREATMENT REQUESTED***

                                     - 99 -
<Page>

successors and assigns a new contract; PROVIDED that the Company shall be
required to execute a new contract with the Collateral Agent only if the
Collateral Agent or its designees, successors or assigns shall within ten (10)
business days of entering into such new contract, cure all defaults for failure
to pay all amounts due and payable to the Company under the Assigned Contract,
including any interest applicable thereon. The new contract shall, subject to
all applicable laws, rules and regulations, contain the same covenants,
agreements, terms, provisions and limitations as the Assigned Contract (except
for any requirements with respect to past performance which have been fulfilled
by the Partnership or the Collateral Agent or its designees, successors and
assigns hereunder).

      SECTION 5. LIABILITY OF SECURED PARTIES

      The Collateral Agent, on behalf of the Secured Parties, and its successors
and assigns, shall have no right or power to enforce the Assigned Contract, and
assumes no duty or obligation thereunder unless and until the Collateral Agent
shall have notified the Company that it has elected to exercise its rights and
remedies under the Security Agreement and to substitute itself in the position
of the Partnership under the Assigned Contracts and has agreed in a written
instrument executed by the Collateral Agent to be bound by all terms and
conditions of the Assigned Contract applicable to the Partnership.

      SECTION 6. FURTHER ASSURANCES

      The Company hereby agrees to execute and deliver all such instruments and
take all such actions as may be reasonably necessary to effectuate fully the
purposes of this Consent, provided, however, that such further assurances shall
not expand the liability, or obligations arising under this Consent or dilute
any rights or remedies otherwise accruing to Company under this Consent.

      SECTION 7. NOTICES

      All notices and other communications hereunder shall be in writing, shall
refer on their face to the Assigned Contract (although failure to so refer shall
not render any such notice or communication ineffective), shall be sent by first
class mail, facsimile, by hand or overnight courier service and shall be
directed:

            (a)   if to the Company, in accordance with the Assigned Contract;

      SECTION 8. MISCELLANEOUS

      (a) GOVERNING LAW. This Consent shall be governed by and construed in
accordance with the law of the State of New York as to all matters (without
giving effect to conflict of law principles). Each of the Company and the
Partnership hereby irrevocably waives, to the fullest extent permitted by law,
any and all right to trial by jury in any legal proceedings arising out of or
relating to this Consent.

      (b) SUBMISSION TO JURISDICTION. Each of the Parties hereby irrevocably and
unconditionally:

                  (i) submits for itself and its property in any legal action or
proceeding relating to this Consent, or for recognition and enforcement of any
judgment in respect thereof, to the non-exclusive general jurisdiction of the

Party at its address set forth in Section 7, or at such other address of which
the other Party shall have been notified pursuant thereto; and

                  (iii) agrees that nothing herein shall affect the right to

      (c) HEADINGS. The descriptive headings of the Articles and Sections of
this Consent are inserted for convenience only and are not intended to affect

(MULTICURRENCY -- CROSS BORDER)

                                     ISDA(R)

                  International Swap Dealers Association, Inc.

                                MASTER AGREEMENT

                            dated as of July 1, 2001

SITHE/INDEPENDENCE POWER PARTNERS, L.P. (a Delaware limited partnership) and
DYNEGY POWER MARKETING, INC. (a Texas corporation) have entered and/or
anticipate entering into one or more transactions (each a "Transaction") that
are or will be governed by this Master Agreement, which includes the schedule
(the "Schedule"), and the documents and other confirming evidence (each a
"Confirmation") exchanged between the parties confirming those Transactions.

Accordingly, the parties agree as follows: --

1.    INTERPRETATION

(a) DEFINITIONS. The terms defined in Section 14 and in the Schedule will have
the meanings therein specified for the purpose of this Master Agreement.

(b) INCONSISTENCY. In the event of any inconsistency between the provisions of
the Schedule and the other provisions of this Master Agreement, the Schedule
will prevail. In the event of any inconsistency between the provisions of any
Confirmation and this Master Agreement (including the Schedule), such
Confirmation will prevail for the purpose of the relevant Transaction.

(c) SINGLE AGREEMENT. All Transactions are entered into in reliance on the fact
that this Master Agreement and all Confirmations form a single agreement between
the parties (collectively referred to as this "Agreement"), and the parties
would not otherwise enter into any Transactions.

2.    OBLIGATIONS

(a)   GENERAL CONDITIONS.

      (i) Each party will make each payment or delivery specified in each
      Confirmation to be made by it, subject to the other provisions of this
      Agreement.

      (ii) Payments under this Agreement will be made on the due date for value
      on that date in the place of the account specified in the relevant
      Confirmation or otherwise pursuant to this Agreement, in freely
      transferable funds and in the manner customary for payments in the
      required currency. Where settlement is by delivery (that is, other than by
      payment), such delivery will be made for receipt on the due date in the
      manner customary for the relevant obligation unless otherwise specified in
      the relevant Confirmation or elsewhere in this Agreement.

      (iii) Each obligation of each party under Section 2(a)(i) is subject to
      (1) the condition precedent that no Event of Default or Potential Event of
      Default with respect to the other party has occurred and is continuing,
      (2) the condition precedent that no Early Termination Date in respect of
      the relevant Transaction has occurred or been effectively designated and
      (3) each other applicable condition precedent specified in this Agreement.

(b) CHANGE OF ACCOUNT. Either party may change its account for receiving a
payment or delivery by giving notice to the other party at least five Local
Business Days prior to the scheduled date for the payment or delivery to which
such change applies unless such other party gives timely notice of a reasonable
objection to such change.

(c) NETTING. If on any date amounts would otherwise be payable:--

                                       1
<Page>

      (i) in the same currency; and

      (ii) in respect of the same Transaction,

by each party to the other, then, on such date, each party's obligation to make
payment of any such amount will be automatically satisfied and discharged and,
if the aggregate amount that would otherwise have been payable by one party
exceeds the aggregate amount that would otherwise have been payable by the other
party, replaced by an obligation upon the party by whom the larger aggregate
amount would have been payable to pay to the other party the excess of the
larger aggregate amount over the smaller aggregate amount.

The parties may elect in respect of two or more Transactions that a net amount
will be determined in respect of all amounts payable on the same date in the
same currency in respect of such Transactions, regardless of whether such
amounts are payable in respect of the same Transaction. The election may be made
in the Schedule or a Confirmation by specifying that subparagraph (ii) above
will not apply to the Transactions identified as being subject to the election,
together with the starting date (in which case subparagraph (ii) above will not,
or will cease to, apply to such Transactions from such date). This election may
be made separately for different groups of Transactions and will apply
separately to each pairing of Offices through which the parties make and receive
payments or deliveries.

(d) DEDUCTION OR WITHHOLDING FOR TAX.

      (i) GROSS-UP. All payments under this Agreement will be made without any
      deduction or withholding for or on account of any Tax unless such
      deduction or withholding is required by any applicable law, as modified by
      the practice of any relevant governmental revenue authority, then in
      effect. If a party is so required to deduct or withhold, then that party
      ("X") will:--

            (1) promptly notify the other party ("Y") of such requirement;

            (2) pay to the relevant authorities the full amount required to be
            deducted or withheld (including the full amount required to be
            deducted or withheld from any additional amount paid by X to Y under
            this Section 2(d)) promptly upon the earlier of determining that
            such deduction or withholding is required or receiving notice that
            such amount has been assessed against Y;

            (3) promptly forward to Y an official receipt (or a certified copy),
            or other documentation reasonably acceptable to Y, evidencing such
            payment to such authorities; and

            (4) if such Tax is an Indemnifiable Tax, pay to Y, in addition to
            the payment to which Y is otherwise entitled under this Agreement,
            such additional amount as is necessary to ensure that the net amount
            actually received by Y (free and clear of Indemnifiable Taxes,
            whether assessed against X or Y) will equal the full amount Y would
            have received had no such deduction or withholding been required.
            However, X will not be required to pay any additional amount to Y to
            the extent that it would not be required to be paid but for:--

                  (A) the failure by Y to comply with or perform any agreement
                  contained in Section 4(a)(i), 4(a)(iii) or 4(d); or

                  (B) the failure of a representation made by Y pursuant to
                  Section 3(f) to be accurate and true unless such failure would
                  not have occurred but for (I) any action taken by a taxing
                  authority, or brought in a court of competent jurisdiction, on
                  or after the date on which a Transaction is entered into
                  (regardless of whether such action is taken or brought with
                  respect to a party to this Agreement) or (II) a Change in Tax
                  Law.

      (ii) LIABILITY. If:--

            (1) X is required by any applicable law, as modified by the practice
            of any relevant governmental revenue authority, to make any
            deduction or withholding in respect of which X would not be required
            to pay an additional amount to Y under Section 2(d)(i)(4);

            (2) X does not so deduct or withhold; and

            (3) a liability resulting from such Tax is assessed directly against
            X,

      then, except to the extent Y has satisfied or then satisfies the liability
      resulting from such Tax, Y will promptly pay to X the amount of such
      liability (including any related liability for interest, but including any

                                       2
<Page>

      related liability for penalties only if Y has failed to comply with or
      perform any agreement contained in Section 4(a)(i), 4(a)(iii) or 4(d)).

(e) DEFAULT INTEREST; OTHER AMOUNTS. Prior to the occurrence or effective
designation of an Early Termination Date in respect of the relevant Transaction,
a party that defaults in the performance of any payment obligation will, to the
extent permitted by law and subject to Section 6(c), be required to pay interest
(before as well as after judgment) on the overdue amount to the other party on
demand in the same currency as such overdue amount, for the period from (and
including) the original due date for payment to (but excluding) the date of
actual payment, at the Default Rate. Such interest will be calculated on the
basis of daily compounding and the actual number of days elapsed. If, prior to
the occurrence or effective designation of an Early Termination Date in respect
of the relevant Transaction, a party defaults in the performance of any
obligation required to be settled by delivery, it will compensate the other
party on demand if and to the extent provided for in the relevant Confirmation
or elsewhere in this Agreement.

3.    REPRESENTATIONS

Each party represents to the other party (which representations will be deemed
to be repeated by each party on each date on which a Transaction is entered into
and, in the case of the representations in Section 3(f), at all times until the
termination of this Agreement) that:--

(a) BASIC REPRESENTATIONS.

      (i) STATUS. It is duly organised and validly existing under the laws of
      the jurisdiction of its organisation or incorporation and, if relevant
      under such laws, in good standing;

      its obligations under this Agreement and any obligations it has under any
      Credit Support Document to which it is a party and has taken all necessary
      action to authorise such execution, delivery and performance;

      (iii) NO VIOLATION OR CONFLICT. Such execution, delivery and performance
      do not violate or conflict with any law applicable to it, any provision of
      its constitutional documents, any order or judgment of any court or other
      agency of government applicable to it or any of its assets or any
      contractual restriction binding on or affecting it or any of its assets;

      (iv) CONSENTS. All governmental and other consents that are required to
      have been obtained by it with respect to this Agreement or any Credit

      force and effect and all conditions of any such consents have been
      complied with; and

      (v) OBLIGATIONS BINDING. Its obligations under this Agreement and any
      Credit Support Document to which it is a party constitute its legal, valid
      and binding obligations, enforceable in accordance with their respective
      terms (subject to applicable bankruptcy, reorganisation, insolvency,
      moratorium or similar laws affecting creditors' rights generally and
      subject, as to enforceability, to equitable principles of general
      application (regardless of whether enforcement is sought in a proceeding
      in equity or at law)).

(b) ABSENCE OF CERTAIN EVENTS. No Event of Default or Potential Event of Default
or, to its knowledge, Termination Event with respect to it has occurred and is
continuing and no such event or circumstance would occur as a result of its
entering into or performing its obligations under this Agreement or any Credit
Support Document to which it is a party.

(c) ABSENCE OF LITIGATION. There is not pending or, to its knowledge, threatened
against it or any of its Affiliates any action, suit or proceeding at law or in
equity or before any court, tribunal, governmental body, agency or official or

against it of this Agreement or any Credit Support Document to which it is a
party or its ability to perform its obligations under this Agreement or such
Credit Support Document.

(d) ACCURACY OF SPECIFIED INFORMATION. All applicable information that is
furnished in writing by or on behalf of it to the other party and is identified
for the purpose of this Section 3(d) in the Schedule is, as of the date of the

4.    AGREEMENTS

Each party agrees with the other that, so long as either party has or may have
any obligation under this Agreement or under any Credit Support Document to
which it is a party:--

(a) FURNISH SPECIFIED INFORMATION. It will deliver to the other party or, in
certain cases under subparagraph (iii) below, to such government or taxing
authority as the other party reasonably directs:--

      (i) any forms, documents or certificates relating to taxation specified in
      the Schedule or any Confirmation;

      (ii) any other documents specified in the Schedule or any Confirmation;
      and

      (iii) upon reasonable demand by such other party, any form or document
      that may be required or reasonably requested in writing in order to allow
      such other party or its Credit Support Provider to make a payment under
      this Agreement or any applicable Credit Support Document without any
      deduction or withholding for or on account of any Tax or with such
      deduction or withholding at a reduced rate (so long as the completion,
      execution or submission of such form or document would not materially
      prejudice the legal or commercial position of the party in receipt of such
      demand), with any such form or document to be accurate and completed in a
      manner reasonably satisfactory to such other party and to be executed and
      to be delivered with any reasonably required certification,

in each case by the date specified in the Schedule or such Confirmation or, if
none is specified, as soon as reasonably practicable.

(b) MAINTAIN AUTHORISATIONS. It will use all reasonable efforts to maintain in
full force and effect all consents of any governmental or other authority that
are required to be obtained by it with respect to this Agreement or any Credit
Support Document to which it is a party and will use all reasonable efforts to
obtain any that may become necessary in the future.

(c) COMPLY WITH LAWS. It will comply in all material respects with all
applicable laws and orders to which it may be subject if failure so to comply
would materially impair its ability to perform its obligations under this
Agreement or any Credit Support Document to which it is a party.

(d) TAX AGREEMENT. It will give notice of any failure of a representation made
by it under Section 3(f) to be accurate and true promptly upon learning of such
failure.

(e) PAYMENT OF STAMP TAX. Subject to Section 11, it will pay any Stamp Tax
levied or imposed upon it or in respect of its execution or performance of this
Agreement by a jurisdiction in which it is incorporated, organised, managed and
controlled, or considered to have its seat, or in which a branch or office
through which it is acting for the purpose of this Agreement is located ("Stamp
Tax Jurisdiction") and will indemnify the other party against any Stamp Tax
levied or imposed upon the other party or in respect of the other party's
execution or performance of this Agreement by any such Stamp Tax Jurisdiction
which is not also a Stamp Tax Jurisdiction with respect to the other party.

5.    EVENTS OF DEFAULT AND TERMINATION EVENTS

(a) EVENTS OF DEFAULT. The occurrence at any time with respect to a party or, if
applicable, any Credit Support Provider of such party or any Specified Entity of
such party of any of the following events constitutes an event of default (an
"Event of Default") with respect to such party:--

      (i) FAILURE TO PAY OR DELIVER. Failure by the party to make, when due, any
      payment under this Agreement or delivery under Section 2(a)(i) or 2(e)
      required to be made by it if such failure is not remedied on or before the
      third Local Business Day after notice of such failure is given to the
      party;

      (ii) BREACH OF AGREEMENT. Failure by the party to comply with or perform
      any agreement or obligation (other than an obligation to make any payment
      under this Agreement or delivery under Section

                                       4
<Page>

      2(a)(i) or 2(e) or to give notice of a Termination Event or any agreement
      or obligation under Section 4(a)(i), 4(a)(iii) or 4(d)) to be complied
      with or performed by the party in accordance with this Agreement if such
      failure is not remedied on or before the thirtieth day after notice of
      such failure is given to the party;

      (iii) CREDIT SUPPORT DEFAULT.

            (1) Failure by the party or any Credit Support Provider of such
            party to comply with or perform any agreement or obligation to be
            complied with or performed by it in accordance with any Credit
            Support Document if such failure is continuing after any applicable
            grace period has elapsed;

            (2) the expiration or termination of such Credit Support Document or
            the failing or ceasing of such Credit Support Document to be in full
            force and effect for the purpose of this Agreement (in either case
            other than in accordance with its terms) prior to the satisfaction
            of all obligations of such party under each Transaction to which
            such Credit Support Document relates without the written consent of
            the other party; or

            (3) the party or such Credit Support Provider disaffirms, disclaims,
            repudiates or rejects, in whole or in part, or challenges the
            validity of, such Credit Support Document;

      (iv) MISREPRESENTATION. A representation (other than a representation
      under Section 3(e) or (f)) made or repeated or deemed to have been made or
      repeated by the party or any Credit Support Provider of such party in this
      Agreement or any Credit Support Document proves to have been incorrect or
      misleading in any material respect when made or repeated or deemed to have
      been made or repeated;

      (v) DEFAULT UNDER SPECIFIED TRANSACTION. The party, any Credit Support
      Provider of such party or any applicable Specified Entity of such party
      (1) defaults under a Specified Transaction and, after giving effect to any
      applicable notice requirement or grace period, there occurs a liquidation
      of, an acceleration of obligations under, or an early termination of, that
      Specified Transaction, (2) defaults, after giving effect to any applicable
      notice requirement or grace period, in making any payment or delivery due
      on the last payment, delivery or exchange date of, or any payment on early
      termination of, a Specified Transaction (or such default continues for at
      least three Local Business Days if there is no applicable notice
      requirement or grace period) or (3) disaffirms, disclaims, repudiates or
      rejects, in whole or in part, a Specified Transaction (or such action is
      taken by any person or entity appointed or empowered to operate it or act
      on its behalf);

      (vi) CROSS DEFAULT. If "Cross Default" is specified in the Schedule as
      applying to the party, the occurrence or existence of (1) a default, event
      of default or other similar condition or event (however described) in
      respect of such party, any Credit Support Provider of such party or any
      applicable Specified Entity of such party under one or more agreements or
      instruments relating to Specified Indebtedness of any of them
      (individually or collectively) in an aggregate amount of not less than the
      applicable Threshold Amount (as specified in the Schedule) which has
      resulted in such Specified Indebtedness becoming, or becoming capable at
      such time of being declared, due and payable under such agreements or
      instruments, before it would otherwise have been due and payable or (2) a
      default by such party, such Credit Support Provider or such Specified
      Entity (individually or collectively) in making one or more payments on
      the due date thereof in an aggregate amount of not less than the
      applicable Threshold Amount under such agreements or instruments (after
      giving effect to any applicable notice requirement or grace period);

      (vii) BANKRUPTCY. The party, any Credit Support Provider of such party or
      any applicable Specified Entity of such party:--

            (1) is dissolved (other than pursuant to a consolidation,
            amalgamation or merger); (2) becomes insolvent or is unable to pay
            its debts or fails or admits in writing its inability generally to
            pay its debts as they become due; (3) makes a general assignment,
            arrangement or composition with or for the benefit of its creditors;
            (4) institutes or has instituted against it a proceeding seeking a
            judgment of insolvency or bankruptcy or any other relief under any
            bankruptcy or insolvency law or other similar law affecting
            creditors' rights, or a petition is presented for its winding-up or
            liquidation, and, in the case of any such proceeding or petition
            instituted or presented against it, such proceeding or petition (A)
            results in a judgment of insolvency or bankruptcy or the entry of an
            order for relief or the making of an order for its winding-up or
            liquidation or (B) is not dismissed, discharged, stayed or
            restrained in each case within 30 days of the institution or

                                       5
<Page>

            presentation thereof; (5) has a resolution passed for its
            winding-up, official management or liquidation (other than pursuant
            to a consolidation, amalgamation or merger); (6) seeks or becomes
            subject to the appointment of an administrator, provisional
            liquidator, conservator, receiver, trustee, custodian or other
            similar official for it or for all or substantially all its assets;
            (7) has a secured party take possession of all or substantially all
            its assets or has a distress, execution, attachment, sequestration
            or other legal process levied, enforced or sued on or against all or
            substantially all its assets and such secured party maintains
            possession, or any such process is not dismissed, discharged, stayed
            or restrained, in each case within 30 days thereafter; (8) causes or
            is subject to any event with respect to it which, under the
            applicable laws of any jurisdiction, has an analogous effect to any
            of the events specified in clauses (1) to (7) (inclusive); or (9)
            takes any action in furtherance of, or indicating its consent to,
            approval of, or acquiescence in, any of the foregoing acts; or

      (viii) MERGER WITHOUT ASSUMPTION. The party or any Credit Support Provider
      of such party consolidates or amalgamates with, or merges with or into, or
      transfers all or substantially all its assets to, another entity and, at
      the time of such consolidation, amalgamation, merger or transfer:--

            (1) the resulting, surviving or transferee entity fails to assume
            all the obligations of such party or such Credit Support Provider
            under this Agreement or any Credit Support Document to which it or
            its predecessor was a party by operation of law or pursuant to an
            agreement reasonably satisfactory to the other party to this
            Agreement; or

            (2) the benefits of any Credit Support Document fail to extend
            (without the consent of the other party) to the performance by such
            resulting, surviving or transferee entity of its obligations under
            this Agreement.

(b) TERMINATION EVENTS. The occurrence at any time with respect to a party or,
if applicable, any Credit Support Provider of such party or any Specified Entity
of such party of any event specified below constitutes an Illegality if the
event is specified in (i) below, a Tax Event if the event is specified in (ii)
below or a Tax Event Upon Merger if the event is specified in (iii) below, and,
if specified to be applicable, a Credit Event Upon Merger if the event is
specified pursuant to (iv) below or an Additional Termination Event if the event
is specified pursuant to (v) below:--

      (i) ILLEGALITY. Due to the adoption of, or any change in, any applicable
      law after the date on which a Transaction is entered into, or due to the
      promulgation of, or any change in, the interpretation by any court,
      tribunal or regulatory authority with competent jurisdiction of any
      applicable law after such date, it becomes unlawful (other than as a
      result of a breach by the party of Section 4(b)) for such party (which
      will be the Affected Party):--

            (1) to perform any absolute or contingent obligation to make a
            payment or delivery or to receive a payment or delivery in respect
            of such Transaction or to comply with any other material provision
            of this Agreement relating to such Transaction; or

            (2) to perform, or for any Credit Support Provider of such party to
            perform, any contingent or other obligation which the party (or such
            Credit Support Provider) has under any Credit Support Document
            relating to such Transaction;

      (ii) TAX EVENT. Due to (x) any action taken by a taxing authority, or
      brought in a court of competent jurisdiction, on or after the date on
      which a Transaction is entered into (regardless of whether such action is
      taken or brought with respect to a party to this Agreement) or (y) a
      Change in Tax Law, the party (which will be the Affected Party) will, or
      there is a substantial likelihood that it will, on the next succeeding
      Scheduled Payment Date (1) be required to pay to the other party an
      additional amount in respect of an Indemnifiable Tax under Section
      2(d)(i)(4) (except in respect of interest under Section 2(e), 6(d)(ii) or
      6(e)) or (2) receive a payment from which an amount is required to be
      deducted or withheld for or on account of a Tax (except in respect of
      interest under Section 2(e), 6(d)(ii) or 6(e)) and no additional amount is
      required to be paid in respect of such Tax under Section 2(d)(i)(4) (other
      than by reason of Section 2(d)(i)(4)(A) or (B));

      (iii) TAX EVENT UPON MERGER. The party (the "Burdened Party") on the next
      succeeding Scheduled Payment Date will either (1) be required to pay an
      additional amount in respect of an Indemnifiable Tax

                                       6
<Page>

      under Section 2(d)(i)(4) (except in respect of interest under Section
      2(e), 6(d)(ii) or 6(e)) or (2) receive a payment from which an amount has
      been deducted or withheld for or on account of any Indemnifiable Tax in
      respect of which the other party is not required to pay an additional
      amount (other than by reason of Section 2(d)(i)(4)(A) or (B)), in either
      case as a result of a party consolidating or amalgamating with, or merging
      with or into, or transferring all or substantially all its assets to,
      another entity (which will be the Affected Party) where such action does
      not constitute an event described in Section 5(a)(viii);

      (iv) CREDIT EVENT UPON MERGER. If "Credit Event Upon Merger" is specified
      in the Schedule as applying to the party, such party ("X"), any Credit
      Support Provider of X or any applicable Specified Entity of X consolidates
      or amalgamates with, or merges with or into, or transfers all or
      substantially all its assets to, another entity and such action does not
      constitute an event described in Section 5(a)(viii) but the
      creditworthiness of the resulting, surviving or transferee entity is
      materially weaker than that of X, such Credit Support Provider or such
      Specified Entity, as the case may be, immediately prior to such action
      (and, in such event, X or its successor or transferee, as appropriate,
      will be the Affected Party); or

      (v) ADDITIONAL TERMINATION EVENT. If any "Additional Termination Event" is
      specified in the Schedule or any Confirmation as applying, the occurrence
      of such event (and, in such event, the Affected Party or Affected Parties
      shall be as specified for such Additional Termination Event in the
      Schedule or such Confirmation).

(c) EVENT OF DEFAULT AND ILLEGALITY. If an event or circumstance which would
otherwise constitute or give rise to an Event of Default also constitutes an
Illegality, it will be treated as an Illegality and will not constitute an Event
of Default.

6.    EARLY TERMINATION

(a) RIGHT TO TERMINATE FOLLOWING EVENT OF DEFAULT. If at any time an Event of
Default with respect to a party (the "Defaulting Party") has occurred and is
then continuing, the other party (the "Non-defaulting Party") may, by not more
than 20 days notice to the Defaulting Party specifying the relevant Event of
Default, designate a day not earlier than the day such notice is effective as an
Early Termination Date in respect of all outstanding Transactions. If, however,
"Automatic Early Termination" is specified in the Schedule as applying to a
party, then an Early Termination Date in respect of all outstanding Transactions
will occur immediately upon the occurrence with respect to such party of an
Event of Default specified in Section 5(a)(vii)(1), (3), (5), (6) or, to the
extent analogous thereto, (8), and as of the time immediately preceding the
institution of the relevant proceeding or the presentation of the relevant
petition upon the occurrence with respect to such party of an Event of Default
specified in Section 5(a)(vii)(4) or, to the extent analogous thereto, (8).

(b)   RIGHT TO TERMINATE FOLLOWING TERMINATION EVENT.

      (i) NOTICE. If a Termination Event occurs, an Affected Party will,
      promptly upon becoming aware of it, notify the other party, specifying the
      nature of that Termination Event and each Affected Transaction and will
      also give such other information about that Termination Event as the other
      party may reasonably require.

      (ii) TRANSFER TO AVOID TERMINATION EVENT. If either an Illegality under
      Section 5(b)(i)(1) or a Tax Event occurs and there is only one Affected
      Party, or if a Tax Event Upon Merger occurs and the Burdened Party is the
      Affected Party, the Affected Party will, as a condition to its right to
      designate an Early Termination Date under Section 6(b)(iv), use all
      reasonable efforts (which will not require such party to incur a loss,
      excluding immaterial, incidental expenses) to transfer within 20 days
      after it gives notice under Section 6(b)(i) all its rights and obligations
      under this Agreement in respect of the Affected Transactions to another of
      its Offices or Affiliates so that such Termination Event ceases to exist.

      If the Affected Party is not able to make such a transfer it will give
      notice to the other party to that effect within such 20 day period,
      whereupon the other party may effect such a transfer within 30 days after
      the notice is given under Section 6(b)(i).

      Any such transfer by a party under this Section 6(b)(ii) will be subject
      to and conditional upon the prior written consent of the other party,
      which consent will not be withheld if such other party's policies in
      effect at such time would permit it to enter into transactions with the
      transferee on the terms proposed.

                                       7
<Page>

      (iii) TWO AFFECTED PARTIES. If an Illegality under Section 5(b)(i)(1) or a
      Tax Event occurs and there are two Affected Parties, each party will use
      all reasonable efforts to reach agreement within 30 days after notice
      thereof is given under Section 6(b)(i) on action to avoid that Termination
      Event.

      (iv) RIGHT TO TERMINATE. If:--

            (1) a transfer under Section 6(b)(ii) or an agreement under Section
            6(b)(iii), as the case may be, has not been effected with respect to
            all Affected Transactions within 30 days after an Affected Party
            gives notice under Section 6(b)(i); or

            (2) an Illegality under Section 5(b)(i)(2), a Credit Event Upon
            Merger or an Additional Termination Event occurs, or a Tax Event
            Upon Merger occurs and the Burdened Party is not the Affected Party,

either party in the case of an Illegality, the Burdened Party in the case of a
Tax Event Upon Merger, any Affected Party in the case of a Tax Event or an
Additional Termination Event if there is more than one Affected Party, or the
party which is not the Affected Party in the case of a Credit Event Upon Merger
or an Additional Termination Event if there is only one Affected Party may, by
not more than 20 days notice to the other party and provided that the relevant
Termination Event is then continuing, designate a day not earlier than the day
such notice is effective as an Early Termination Date in respect of all Affected
Transactions.

(c) EFFECT OF DESIGNATION.

      (i) If notice designating an Early Termination Date is given under Section
      6(a) or (b), the Early Termination Date will occur on the date so
      designated, whether or not the relevant Event of Default or Termination
      Event is then continuing.

      (ii) Upon the occurrence or effective designation of an Early Termination
      Date, no further payments or deliveries under Section 2(a)(i) or 2(e) in
      respect of the Terminated Transactions will be required to be made, but
      without prejudice to the other provisions of this Agreement. The amount,
      if any, payable in respect of an Early Termination Date shall be
      determined pursuant to Section 6(e).

(d) CALCULATIONS.

      (i) STATEMENT. On or as soon as reasonably practicable following the
      occurrence of an Early Termination Date, each party will make the
      calculations on its part, if any, contemplated by Section 6(e) and will
      provide to the other party a statement (1) showing, in reasonable detail,
      such calculations (including all relevant quotations and specifying any
      amount payable under Section 6(e)) and (2) giving details of the relevant
      account to which any amount payable to it is to be paid. In the absence of
      written confirmation from the source of a quotation obtained in
      determining a Market Quotation, the records of the party obtaining such
      quotation will be conclusive evidence of the existence and accuracy of
      such quotation.

      (ii) PAYMENT DATE. An amount calculated as being due in respect of any
      Early Termination Date under Section 6(e) will be payable on the day that
      notice of the amount payable is effective (in the case of an Early
      Termination Date which is designated or occurs as a result of an Event of
      Default) and on the day which is two Local Business Days after the day on
      which notice of the amount payable is effective (in the case of an Early
      Termination Date which is designated as a result of a Termination Event).
      Such amount will be paid together with (to the extent permitted under
      applicable law) interest thereon (before as well as after judgment) in the
      Termination Currency, from (and including) the relevant Early Termination
      Date to (but excluding) the date such amount is paid, at the Applicable
      Rate. Such interest will be calculated on the basis of daily compounding
      and the actual number of days elapsed.

(e) PAYMENTS ON EARLY TERMINATION. If an Early Termination Date occurs, the
following provisions shall apply based on the parties' election in the Schedule
of a payment measure, either "Market Quotation" or "Loss", and a payment method,
either the "First Method" or the "Second Method". If the parties fail to
designate a payment measure or payment method in the Schedule, it will be deemed
that "Market Quotation" or the "Second Method", as the case may be, shall apply.
The amount, if any, payable in respect of an Early Termination Date and
determined pursuant to this Section will be subject to any Set-off

      (i) EVENTS OF DEFAULT. If the Early Termination Date results from an Event
      of Default:--

                                       8
<Page>

            (1) FIRST METHOD AND MARKET QUOTATION. If the First Method and
            Market Quotation apply, the Defaulting Party will pay to the
            Non-defaulting Party the excess, if a positive number, of (A) the
            sum of the Settlement Amount (determined by the Non-defaulting
            Party) in respect of the Terminated Transactions and the Termination
            Currency Equivalent of the Unpaid Amounts owing to the
            Non-defaulting Party over (B) the Termination Currency Equivalent of
            the Unpaid Amounts owing to the Defaulting Party.

            (2) FIRST METHOD AND LOSS. If the First Method and Loss apply, the
            Defaulting Party will pay to the Non-defaulting Party, if a positive
            number, the Non-defaulting Party's Loss in respect of this
            Agreement.

            (3) SECOND METHOD AND MARKET QUOTATION. If the Second Method and
            Market Quotation apply, an amount will be payable equal to (A) the
            sum of the Settlement Amount (determined by the Non-defaulting
            Party) in respect of the Terminated Transactions and the Termination
            Currency Equivalent of the Unpaid Amounts owing to the
            Non-defaulting Party less (B) the Termination Currency Equivalent of
            the Unpaid Amounts owing to the Defaulting Party. If that amount is
            a positive number, the Defaulting Party will pay it to the
            Non-defaulting Party; if it is a negative number, the Non-defaulting
            Party will pay the absolute value of that amount to the Defaulting
            Party.

            (4) SECOND METHOD AND LOSS. If the Second Method and Loss apply, an
            amount will be payable equal to the Non-defaulting Party's Loss in
            respect of this Agreement. If that amount is a positive number, the
            Defaulting Party will pay it to the Non-defaulting Party; if it is a
            negative number, the Non-defaulting Party will pay the absolute
            value of that amount to the Defaulting Party.

      (ii) TERMINATION EVENTS. If the Early Termination Date results from a
      Termination Event:--

            (1) ONE AFFECTED PARTY. If there is one Affected Party, the amount
            payable will be determined in accordance with Section 6(e)(i)(3), if
            Market Quotation applies, or Section 6(e)(i)(4), if Loss applies,
            except that, in either case, references to the Defaulting Party and
            to the Non-defaulting Party will be deemed to be references to the
            Affected Party and the party which is not the Affected Party,
            respectively, and, if Loss applies and fewer than all the
            Transactions are being terminated, Loss shall be calculated in
            respect of all Terminated Transactions.

            (2) TWO AFFECTED PARTIES. If there are two Affected Parties:--

                  (A) if Market Quotation applies, each party will determine a
                  Settlement Amount in respect of the Terminated Transactions,
                  and an amount will be payable equal to (I) the sum of (a)
                  one-half of the difference between the Settlement Amount of
                  the party with the higher Settlement Amount ("X") and the
                  Settlement Amount of the party with the lower Settlement
                  Amount ("Y"); and (b) the Termination Currency Equivalent of
                  the Unpaid Amounts owing to X less (II) the Termination
                  Currency Equivalent of the Unpaid Amounts owing to Y, and

                  (B) if Loss applies, each party will determine its Loss in
                  respect of this Agreement (or, if fewer than all the
                  Transactions are being terminated, in respect of all
                  Terminated Transactions) and an amount will be payable equal
                  to one-half of the difference between the Loss of the party
                  with the higher Loss ("X") and the Loss of the party with the
                  lower Loss ("Y").

            If the amount payable is a positive number, Y will pay it to X; if
            it is a negative number, X will pay the absolute value of that
            amount to Y.

      (iii) ADJUSTMENT FOR BANKRUPTCY. In circumstances where an Early
      Termination Date occurs because "Automatic Early Termination" applies in
      respect of a party, the amount determined under this Section 6(e) will be
      subject to such adjustments as are appropriate and permitted by law to
      reflect any payments or deliveries made by one party to the other under
      this Agreement (and retained by such other party) during the period from
      the relevant Early Termination Date to the date for payment determined
      under Section 6(d)(ii).

                                       9
<Page>

      (iv) PRE-ESTIMATE. The parties agree that if Market Quotation applies an
      amount recoverable under this Section 6(e) is a reasonable pre-estimate of
      loss and not a penalty. Such amount is payable for the loss of bargain and
      the loss of protection against future risks and except as otherwise
      provided in this Agreement neither party will be entitled to recover any
      additional damages as a consequence of such losses.

7.    TRANSFER

Subject to Section 6(b)(ii), neither this Agreement nor any interest or
obligation in or under this Agreement may be transferred (whether by way of
security or otherwise) by either party without the prior written consent of the
other party, except that:--

(a) a party may make such a transfer of this Agreement pursuant to a
consolidation or amalgamation with, or merger with or into, or transfer of all
or substantially all its assets to, another entity (but without prejudice to any
other right or remedy under this Agreement); and

(b) a party may make such a transfer of all or any part of its interest in any
amount payable to it from a Defaulting Party under Section 6(e).

Any purported transfer that is not in compliance with this Section will be void.

8.    CONTRACTUAL CURRENCY

(a) PAYMENT IN THE CONTRACTUAL CURRENCY. Each payment under this Agreement will
be made in the relevant currency specified in this Agreement for that payment
(the "Contractual Currency"). To the extent permitted by applicable law, any
obligation to make payments under this Agreement in the Contractual Currency
will not be discharged or satisfied by any tender in any currency other than the
Contractual Currency, except to the extent such tender results in the actual
receipt by the party to which payment is owed, acting in a reasonable manner and
in good faith in converting the currency so tendered into the Contractual
Currency, of the full amount in the Contractual Currency of all amounts payable
in respect of this Agreement. If for any reason the amount in the Contractual
Currency so received falls short of the amount in the Contractual Currency
payable in respect of this Agreement, the party required to make the payment
will, to the extent permitted by applicable law, immediately pay such additional
amount in the Contractual Currency as may be necessary to compensate for the
shortfall. If for any reason the amount in the Contractual Currency so received
exceeds the amount in the Contractual Currency payable in respect of this
Agreement, the party receiving the payment will refund promptly the amount of
such excess.

(b) JUDGMENTS. To the extent permitted by applicable law, if any judgment or
order expressed in a currency other than the Contractual Currency is rendered
(i) for the payment of any amount owing in respect of this Agreement, (ii) for
the payment of any amount relating to any early termination in respect of this
Agreement or (iii) in respect of a judgment or order of another court for the
payment of any amount described in (i) or (ii) above, the party seeking
recovery, after recovery in full of the aggregate amount to which such party is
entitled pursuant to the judgment or order, will be entitled to receive
immediately from the other party the amount of any shortfall of the Contractual
Currency received by such party as a consequence of sums paid in such other
currency and will refund promptly to the other party any excess of the
Contractual Currency received by such party as a consequence of sums paid in
such other currency if such shortfall or such excess arises or results from any
variation between the rate of exchange at which the Contractual Currency is
converted into the currency of the judgment or order for the purposes of such
judgment or order and the rate of exchange at which such party is able, acting
in a reasonable manner and in good faith in converting the currency received
into the Contractual Currency, to purchase the Contractual Currency with the
amount of the currency of the judgment or order actually received by such party.
The term "rate of exchange" includes, without limitation, any premiums and costs
of exchange payable in connection with the purchase of or conversion into the
Contractual Currency.

(c) SEPARATE INDEMNITIES. To the extent permitted by applicable law, these
indemnities constitute separate and independent obligations from the other
obligations in this Agreement, will be enforceable as separate and independent
causes of action, will apply notwithstanding any indulgence granted by the party
to which any payment is owed and will not be affected by judgment being obtained
or claim or proof being made for any other sums payable in respect of this
Agreement.

(d) EVIDENCE OF LOSS. For the purpose of this Section 8, it will be sufficient
for a party to demonstrate that it would have suffered a loss had an actual
exchange or purchase been made.

                                       10

9.    MISCELLANEOUS

(a) ENTIRE AGREEMENT. This Agreement constitutes the entire agreement and
understanding of the parties with respect to its subject matter and supersedes
all oral communication and prior writings with respect thereto.

(b) AMENDMENTS. No amendment, modification or waiver in respect of this
Agreement will be effective unless in writing (including a writing evidenced by
a facsimile transmission) and executed by each of the parties or confirmed by an
exchange of telexes or electronic messages on an electronic messaging system.

(c) SURVIVAL OF OBLIGATIONS. Without prejudice to Sections 2(a)(iii) and
6(c)(ii), the obligations of the parties under this Agreement will survive the
termination of any Transaction.

(d) REMEDIES CUMULATIVE. Except as provided in this Agreement, the rights,
powers, remedies and privileges provided in this Agreement are cumulative and
not exclusive of any rights, powers, remedies and privileges provided by law.

(e) COUNTERPARTS AND CONFIRMATIONS.

      (i) This Agreement (and each amendment, modification and waiver in respect
      of it) may be executed and delivered in counterparts (including by
      facsimile transmission), each of which will be deemed an original.

      (ii) The parties intend that they are legally bound by the terms of each
      Transaction from the moment they agree to those terms (whether orally or
      otherwise). A Confirmation shall be entered into as soon as practicable
      and may be executed and delivered in counterparts (including by facsimile
      transmission) or be created by an exchange of telexes or by an exchange of
      electronic messages on an electronic messaging system, which in each case
      will be sufficient for all purposes to evidence a binding supplement to
      this Agreement. The parties will specify therein or through another
      effective means that any such counterpart, telex or electronic message
      constitutes a Confirmation.

(f) NO WAIVER OF RIGHTS. A failure or delay in exercising any right, power or
privilege in respect of this Agreement will not be presumed to operate as a
waiver, and a single or partial exercise of any right, power or privilege will
not be presumed to preclude any subsequent or further exercise, of that right,
power or privilege or the exercise of any other right, power or privilege.

(g) HEADINGS. The headings used in this Agreement are for convenience of
reference only and are not to affect the construction of or to be taken into
consideration in interpreting this Agreement.

10.   OFFICES; MULTIBRANCH PARTIES

(a) If Section 10(a) is specified in the Schedule as applying, each party that
enters into a Transaction through an Office other than its head or home office
represents to the other party that, notwithstanding the place of booking office
or jurisdiction of incorporation or organisation of such party, the obligations
of such party are the same as if it had entered into the Transaction through its
head or home office. This representation will be deemed to be repeated by such
party on each date on which a Transaction is entered into.

(b) Neither party may change the Office through which it makes and receives
payments or deliveries for the purpose of a Transaction without the prior
written consent of the other party.

(c) If a party is specified as a Multibranch Party in the Schedule, such
Multibranch Party may make and receive payments or deliveries under any
Transaction through any Office listed in the Schedule, and the Office through
which it makes and receives payments or deliveries with respect to a Transaction
will be specified in the relevant Confirmation.

11.   EXPENSES

A Defaulting Party will, on demand, indemnify and hold harmless the other party
for and against all reasonable out-of-pocket expenses, including legal fees and
Stamp Tax, incurred by such other party by reason of the enforcement and
protection of its rights under this Agreement or any Credit Support Document to
which the Defaulting Party is a party or by reason of the early termination of
any Transaction, including, but not limited to, costs of collection.

      will not be met by a transmission report generated by the sender's
      facsimile machine);

      (iv) if sent by certified or registered mail (airmail, if overseas) or the
      equivalent (return receipt requested), on the date that mail is delivered

      (v) if sent by electronic messaging system, on the date that electronic
      message is received,

unless the date of that delivery (or attempted delivery) or that receipt, as

Business Day, in which case that communication shall be deemed given and
effective on the first following day that is a Local Business Day.

(b) CHANGE OF ADDRESSES. Either party may by notice to the other change the
address, telex or facsimile number or electronic messaging system details at

13.   GOVERNING LAW AND JURISDICTION

(a) GOVERNING LAW. This Agreement will be governed by and construed in
accordance with the law specified in the Schedule.

(b) JURISDICTION. With respect to any suit, action or proceedings relating to
this Agreement ("Proceedings"), each party irrevocably:--

      (i) submits to the jurisdiction of the English courts, if this Agreement
      is expressed to be governed by English law, or to the non-exclusive
      jurisdiction of the courts of the State of New York and the United States
      District Court located in the Borough of Manhattan in New York City, if
      this Agreement is expressed to be governed by the laws of the State of New
      York; and

      (ii) waives any objection which it may have at any time to the laying of
      venue of any Proceedings brought in any such court, waives any claim that
      such Proceedings have been brought in an inconvenient forum and further
      waives the right to object, with respect to such Proceedings, that such
      court does not have any jurisdiction over such party.

Nothing in this Agreement precludes either party from bringing Proceedings in
any other jurisdiction (outside, if this Agreement is expressed to be governed
by English law, the Contracting States, as defined in Section 1(3) of the Civil
Jurisdiction and Judgments Act 1982 or any modification, extension or
re-enactment thereof for the time being in force) nor will the bringing of
Proceedings in any one or more jurisdictions preclude the bringing of
Proceedings in any other jurisdiction.

(c) SERVICE OF PROCESS. Each party irrevocably appoints the Process Agent (if
any) specified opposite its name in the Schedule to receive, for it and on its
behalf, service of process in any Proceedings. If for any reason any party's
Process Agent is unable to act as such, such party will promptly notify the
other party and within 30 days appoint a substitute process agent acceptable to
the other party. The parties irrevocably consent to service of process given in
the manner provided for notices in Section 12. Nothing in this Agreement will
affect the right of either party to serve process in any other manner permitted
by law.

(d) WAIVER OF IMMUNITIES. Each party irrevocably waives, to the fullest extent
permitted by applicable law, with respect to itself and its revenues and assets
(irrespective of their use or intended use), all immunity on the grounds of
sovereignty or other similar grounds from (i) suit, (ii) jurisdiction of any
court, (iii) relief by way of injunction, order for specific performance or for
recovery of property, (iv) attachment of its assets (whether before or after
judgment) and (v) execution or enforcement of any judgment to which it or its
revenues or assets might

                                       12
<Page>

otherwise be entitled in any Proceedings in the courts of any jurisdiction and
irrevocably agrees, to the extent permitted by applicable law, that it will not
claim any such immunity in any Proceedings.

relevant rates or prices from one or more leading dealers in the relevant
markets.

"MARKET QUOTATION" means, with respect to one or more Terminated Transactions
and a party making the determination, an amount determined on the basis of
quotations from Reference Market-makers. Each quotation will be for an amount,
if any, that would be paid to such party (expressed as a negative number) or by
such party (expressed as a positive number) in consideration of an agreement
between such party (taking into account any existing Credit Support Document
with respect to the obligations of such party) and the quoting Reference
Market-maker to enter into a transaction (the "Replacement Transaction") that
would have the effect of preserving for such party the economic equivalent of
any payment or delivery (whether the underlying obligation was absolute or
contingent and assuming the satisfaction of each applicable condition precedent)
by the parties under Section 2(a)(i) in respect of such Terminated Transaction
or group of Terminated Transactions that would, but for the occurrence of the
relevant Early Termination Date, have been required after that date. For this
purpose, Unpaid Amounts in respect of the Terminated Transaction or group of
Terminated Transactions are to be excluded but, without limitation, any payment
or delivery that would, but for the relevant Early Termination Date, have been
required (assuming satisfaction of each applicable condition precedent) after
that Early Termination Date is to be included. The Replacement Transaction would
be subject to such documentation as such party and the Reference Market-maker
may, in good faith, agree. The party making the determination (or its agent)
will request each Reference Market-maker to provide its quotation to the extent
reasonably practicable as of the same day and time (without regard to different
time zones) on or as soon as reasonably practicable after the relevant Early
Termination Date. The day and time as of which those quotations are to be
obtained will be selected in good faith by the party obliged to make a
determination under Section 6(e), and, if each party is so obliged, after
consultation with the other. If more than three quotations are provided, the
Market Quotation will be the arithmetic mean of the quotations, without regard
to the quotations having the highest and lowest values. If exactly three such
quotations are provided, the Market Quotation will be the quotation remaining
after disregarding the highest and lowest quotations. For this purpose, if more
than one quotation has the same highest value or lowest value, then one of such
quotations shall be disregarded. If fewer than three quotations are provided, it
will be deemed that the Market Quotation in respect of such Terminated
Transaction or group of Terminated Transactions cannot be determined.

"NON-DEFAULT RATE" means a rate per annum equal to the cost (without proof or
evidence of any actual cost) to the Non-defaulting Party (as certified by it) if
it were to fund the relevant amount.

on, such payer.

"SETTLEMENT AMOUNT" means, with respect to a party and any Early Termination
Date, the sum of:--

positive or negative) for each Terminated Transaction or group of Terminated
Transactions for which a Market Quotation is determined; and

(b) such party's Loss (whether positive or negative and without reference to any
Unpaid Amounts) for each Terminated Transaction or group of Terminated
Transactions for which a Market Quotation cannot be determined or would not (in
the reasonable belief of the party making the determination) produce a
commercially reasonable result.

"SPECIFIED ENTITY" has the meanings specified in the Schedule.

"SPECIFIED INDEBTEDNESS" means, subject to the Schedule, any obligation (whether
present or future, contingent or otherwise, as principal or surety or otherwise)
in respect of borrowed money.

the Termination Currency, such Termination Currency amount and, in respect of
any amount denominated in a currency other than the Termination Currency (the
"Other Currency"), the amount in the Termination Currency determined by the
party making the relevant determination as being required to purchase such
amount of such Other Currency as at the relevant Early Termination Date, or, if
the relevant Market Quotation or Loss (as the case may be), is determined as of
a later date, that later date, with the Termination Currency at the rate equal
to the spot exchange rate of the foreign exchange agent (selected as provided
below) for the purchase of such Other Currency with the Termination Currency at
or about 11:00 a.m. (in the city in which such foreign exchange agent is
located) on such date as would be customary for the determination of such a rate
for the purchase of such Other Currency for value on the relevant Early
Termination Date or that later date. The foreign exchange agent will, if only
one party is obliged to make a determination under Section 6(e), be selected in
good faith by that party and otherwise will be agreed by the parties.

"TERMINATION EVENT" means an Illegality, a Tax Event or a Tax Event Upon Merger
or, if specified to be applicable, a Credit Event Upon Merger or an Additional

Date, the aggregate of (a) in respect of all Terminated Transactions, the
amounts that became payable (or that would have become payable but for Section
2(a)(iii)) to such party under Section 2(a)(i) on or prior to such Early
Termination Date and which remain unpaid as at such Early Termination Date and
(b) in respect of each Terminated Transaction, for each obligation under Section
2(a)(i) which was (or would have been but for Section 2(a)(iii)) required to be
settled by delivery to such party on or prior to such Early Termination Date and
which has not been so settled as at such Early Termination Date, an amount equal
to the fair market value of that which was (or would have been) required to be
delivered as of the originally scheduled date for delivery, in each case
together with (to the extent permitted under applicable law) interest, in the
currency of such amounts, from (and including) the date such amounts or
obligations were or would have been required to have been paid or performed to
(but excluding) such Early Termination Date, at the Applicable Rate. Such
amounts of interest will be calculated on the basis of daily compounding and the
actual number of days elapsed. The fair market value of any obligation referred
to in clause (b) above shall be reasonably determined by the party obliged to
make the determination under Section 6(e) or, if each party is so obliged, it
shall be the average of the Termination Currency Equivalents of the fair market
values reasonably determined by both parties.
