                   MASTER ENERGY PURCHASE AND SALE AGREEMENT

      This Master Energy Purchase and Sale Agreement (this "Master Agreement"
and together with all Transactions, collectively, the "Agreement") is entered
into effective as of the 12th day of April, 2001 (the "Effective Date") by and
between Enron Energy Services, Inc., a Delaware corporation ("EESI"), and
Callaway Golf Company, a Delaware corporation ("Customer"). Each of EESI and
Customer may also be referred to individually as "Party" or collectively as
"Parties." The Party selling Energy pursuant to a Transaction shall be referred
to as the "Seller," and the Party purchasing Energy pursuant to a Transaction
shall be referred to as the "Buyer." The definitions set forth in Appendix "1"
shall apply to this Agreement.


                                   SECTION 1.
                               SCOPE OF AGREEMENT

1.1.  SCOPE OF AGREEMENT. From time to time, the Parties may, but shall not be
obligated to, enter into Transactions for the purchase or sale of Energy
hereunder. Each Transaction shall be effectuated and evidenced in accordance
with this Master Agreement and shall constitute a part of this Master Agreement.
The Parties are relying upon the fact that all Transactions, together with this
Master Agreement, shall constitute a single integrated agreement, and that the
Parties would not otherwise enter into any Transaction. Any conflict between
this Master Agreement and a Transaction shall be resolved in favor the
Transaction. This Master Agreement shall govern all Transactions between the
Parties from and after the Effective Date unless expressly stated otherwise and
shall govern all transactions between the Parties entered into prior to the
date hereof that relate to the purchase and sale of Energy.

1.2.  TRANSACTION PROCEDURES. Each Transaction shall be effectuated and
evidenced by a written Confirmation Letter executed by the Parties. The
specific terms to be established by the Parties for each Transaction shall
include the identity of the Buyer and Seller, the Period of Delivery, the
Contract Price, the Delivery Point, the Contract Quantity, whether the
Transaction is Firm or Non-Firm and such other terms as the Parties shall agree
upon.

1.3.  TERM OF AGREEMENT. The term of this Master Agreement shall commence on
the Effective Date and shall remain in effect for a period of five (5) years
from the Effective Date, and shall thereafter remain in effect until terminated
by either Party on 30 days prior written notice ("Master Term"); provided,
however, that this Master Agreement shall remain in effect with respect to any
Transaction(s) entered into prior to the end of the Master Term until both
Parties have fulfilled all their obligations with respect to such
Transaction(s).


                                   SECTION 2.
                         REPRESENTATIONS AND WARRANTIES

On the Effective Date and on the date of entering into each Transaction, each
Party represents and warrants to the other Party that: (i) it is duly
organized, validly existing and in good standing under the laws of the
jurisdiction of its formation and is qualified to conduct its business in each
jurisdiction in which a Transaction will be performed by it, (ii) it has all
regulatory authorizations necessary for it to legally perform its obligations
under this Master Agreement and each Transaction, (iii) the execution, delivery
and performance of this Master Agreement and each Transaction are within its
powers, have been duly authorized by all necessary action and do not violate
any of the terms and conditions in its governing documents, any contracts to
which it is a party or any Law applicable to it, (iv) this Master Agreement and
each Transaction when entered into in accordance with this Master Agreement
constitutes its legally valid and binding obligation enforceable against it in
accordance with its terms, subject to any Equitable Defenses, (v) there are no
Bankruptcy Proceedings pending or being contemplated by it or, to its
knowledge, threatened against it, (vi) there are no Legal Proceedings that
materially adversely affect its ability to perform its obligations under this
Master Agreement and each Transaction, and (vii) it has knowledge and
experience in financial matters and the electric industry that enable it to
evaluate the merits and risks of entering into this Master Agreement and each
Transaction.

                                   SECTION 3.
                           OBLIGATIONS AND DELIVERIES

3.1.  SELLER'S AND BUYER'S OBLIGATIONS. With respect to each Transaction and
subject to the terms of this Master Agreement, Seller shall sell and deliver,
or cause to be delivered, and Buyer shall purchase and receive, or cause to be
received, at the Delivery Point the Contract Quantity, and Buyer shall pay
Seller the Contract Price. Seller shall be responsible for any costs or charges
imposed on or associated with the delivery of the Contract Quantity, including
control area services, inadvertent energy flows, transmission losses and loss
charges relating to the transmission of the Contract Quantity, up to the
Delivery Point. Buyer shall be responsible for any costs or charges imposed on
or associated with the Contract Quantity, including control area services,
inadvertent energy flows, transmission losses and loss charges relating to the
transmission of the Contract Quantity, at and from the Delivery Point.

3.2.  TRANSMISSION AND SCHEDULING. Seller shall arrange and be responsible for
transmission service to the Delivery Point and shall Schedule or arrange for
Scheduling services with its Transmission Providers to deliver the Energy to
the Delivery Point. Buyer shall arrange and be responsible for transmission
service at and from the Delivery Point and shall Schedule or arrange for
Scheduling services with its Transmission Providers to receive the Energy at
the Delivery Point. Each Party shall designate authorized representatives or
agents to effect the Scheduling of the Contract Quantity of Energy.

3.3.  TITLE, RISK OF LOSS AND INDEMNITY. As between the Parties, Seller shall
be deemed to be in exclusive control (and responsible for any damages or injury
caused thereby) of the Energy prior to the Delivery Point, and Buyer shall be
deemed to be in exclusive control (and responsible for any damages or injury
caused thereby) of the Energy at and from the Delivery Point. Seller warrants
that it will deliver to Buyer the Contract Quantity free and clear of all
liens, claims and encumbrances arising prior to the Delivery Point. Title to
and risk of loss related to the Contract Quantity shall transfer from Seller to
Buyer at the Delivery Point. Seller and Buyer shall each indemnify, defend and
hold harmless the other Party from any Claims arising from any act or incident
occurring when title to the Energy is vested in the indemnifying Party.


3.4.  FORCE MAJEURE. If either Party is rendered unable by Force Majeure to
carry out, in whole or in part, its obligations under a Transaction and such
Party gives notice and full details of the event to the other Party as soon as
practicable after the occurrence of the event, then during the pendency of such
Force Majeure but for no longer period, the obligations of the Party affected
by the event (other than the obligation to make payments then due or becoming
due with respect to performance prior to the event) shall be suspended to the
extent required. The party affected by the Force Majeure shall remedy the Force
Majeure with all reasonable dispatch; provided, however, that this provision
shall not require Seller to deliver, or Buyer to receive, Energy at points
other than the Delivery Point.

      3.4.1.   FORCE MAJEURE SERVICE. In the case of a Force Majeure event,
where EESI is the Seller, EESI will use commercially reasonable efforts to
procure and provide to Customer the Contract Quantity under each affected
Transaction from alternate sources and/or transportation routes or other
available means ("Force Majeure Service"); provided that EESI will perform such
Force Majeure Service only with Customer's consent, and Customer will bear all
incremental costs associated with such Force Majeure Service, which incremental
costs will be separate from and in addition to any amounts due from Customer
under the applicable Transaction.

3.5.  BUYER'S COVER REMEDY FOR SELLER'S FAILURE TO DELIVER IN FIRM TRANSACTIONS.
Unless excused by Force Majeure or Buyer's failure to perform, if Seller fails
to Schedule and/or deliver all or part of the Contract Quantity pursuant to a
Firm Transaction, Seller shall pay Buyer an amount for each unit of Energy in
such deficiency equal to the positive difference, if any, obtained by
subtracting the Contract Price from the Replacement Price. "Replacement Price"
means the price at which Buyer, acting in a commercially reasonable manner,
purchases substitute units of Energy not delivered by Seller (plus costs
reasonably incurred by Buyer in purchasing substitute units of Energy, including
additional Transmission Charges and Penalties (to the extent not duplicative of
other charges incurred for Energy), if any, incurred by Buyer) or, absent a
purchase, the market price for such quantity at such Delivery Point as
determined by Buyer in a commercially reasonable manner. Amounts calculated
pursuant to this Section 3.5 shall be subject to Section 5.2. and amounts
payable pursuant to this Section 3.5 shall be


                                       2.
   3
payable on or before three (3) Business Days after receipt of an invoice from
Buyer.

3.6  SELLER'S COVER REMEDY FOR BUYER'S FAILURE TO RECEIVE IN FIRM TRANSACTIONS.
Unless excused by Force Majeure or Seller's failure to perform, if Buyer fails
to Schedule and/or receive all or part of the Contract Quantity pursuant to a
Firm Transaction, Buyer shall pay Seller an amount for each unit of Energy in
such deficiency equal to the sum of (1) the positive difference, if any,
obtained by subtracting the Sales Price from the Contract Price, and (2)
additional costs reasonably incurred by Seller in reselling such Energy not
received by Buyer, including additional Transmission Charges, if any. "Sales
Price" means the price per unit of Energy at which Seller, acting in a
commercially reasonable manner, resells or would be able to resell (if at all),
the Energy not received by Buyer, including additional Transmission Charges and
Penalties (to the extent not duplicative of other charges incurred for Energy),
if any, incurred by Seller. Amounts calculated pursuant to this Section 3.6
shall be subject to Section 5.2 and amounts payable pursuant to this Section 3.6
shall be payable on or before three (3) Business Days after receipt of an
invoice from Seller.

3.7  FAILURE TO DELIVER/RECEIVE IN NON-FIRM TRANSACTIONS. A Party may be excused
from delivering or receiving the Contract Quantity, in whole or in part, in a
Non-Firm Transaction for any reason without liability unless otherwise provided
in a Confirmation Letter.

                                   SECTION 4.
                             DEFAULTS AND REMEDIES

4.1. EVENTS OF DEFAULT. An "Event of Default" shall mean with respect to a Party
     ("Defaulting Party"):

(a)  the failure by the Defaulting Party to make, when due, any payment required
     pursuant to this Agreement if such failure is not remedied within three (3)
     Business Days after written notice of such failure is given to the
     Defaulting Party by the other Party ("Non-Defaulting Party") and provided
     the payment is not the subject of a good faith dispute as described in
     Section 6; or

(b)  any representation or warranty made by the Defaulting Party herein shall at
     any time prove to be false or misleading in any material respect; or

(c)  the failure by the Defaulting Party to perform any covenant set forth in
     this Agreement (other than the events that are otherwise specifically
     covered in this Section 4.1 as a separate Event of Default or its
     obligations to deliver or receive Energy a remedy for which is provided in
     Section 3), and such failure is not excused by Force Majeure or cured
     within five (5) Business Days after written notice thereof to the
     Defaulting Party; or

(d)  the Defaulting Party shall be subject to a Bankruptcy Proceeding; or

(e)  breach or default of the Defaulting Party or any of its subsidiaries with
     respect to any other term of any indebtedness, lease or other obligation in
     an amount in excess of $1,000,000, if the effect of such failure, default
     or breach is to permit the holder of the indebtedness, lease or other
     obligation, with the passage of time, to declare such to be due prior to
     its stated maturity.

4.2. EARLY TERMINATION DATE. If an Event of Default occurs with respect to a
Defaulting Party at any time during the Master Term, the Non-Defaulting Party
may, in its sole discretion, for so long as the Event of Default is continuing.

(a)  by no more than twenty (20) days notice to the Defaulting Party, designate
     a day no earlier than the day such notice is effective as an early
     termination date ("Early Termination Date") on which all Transactions shall
     terminate (individually a "Terminated Transaction" and collectively the
     "Terminated Transactions"); and

(b)  withhold any payments due in respect of the Terminated Transactions;
     provided, however, upon the occurrence of any Event of Default listed in
     item (d) of Section 4.1 as it may apply to any Party, all Transactions and
     this Agreement in respect thereof shall automatically terminate, without
     notice, and without any other action by either Party as if an Early
     Termination Date had been declared immediately prior to such event.



                                       3.

4.3. TERMINATION PAYMENT CALCULATION.

(a)  If an Early Termination Date has been designated, the Non-Defaulting Party
     shall in good faith calculate its Gains, Losses and Costs resulting from
     the termination of the Terminated Transactions.

     As used herein with respect to each Party:

     (1)   "GAINS" means, with respect to a Party, an amount equal to the
           present value of the economic benefit (exclusive of Costs), if any,
           to it resulting from the termination of its obligations with respect
           to a Terminated Transaction, determined in a commercially reasonable
           manner;

     (ii)  "LOSSES" means, with respect to a Party, an amount equal to the
           present value of the economic loss (exclusive of Costs), if any, to
           it resulting from the termination of its obligations with respect to
           a Terminated Transaction, determined in a commercially reasonable
           manner; and

     (iii) "COSTS" means, with respect to a Party, brokerage fees, commissions
           and other similar transaction costs and expenses reasonably incurred
           by such Party either in terminating any arrangement pursuant to which
           it has hedged its obligations or entering into new arrangements which
           replace a Terminated Transaction, and attorneys' fees, if any,
           incurred in connection with enforcing its rights under this
           Agreement.

(b)  The Gains, Losses and Costs shall be determined by comparing the value of
     the remaining term, Contract Quantities and Contract Prices under each
     Terminated Transaction had it not been terminated to the equivalent
     quantities and relevant market prices for the remaining term either quoted
     by a bona fide third-party offer or which are reasonably expected to be
     available in the market under a replacement contract for each Terminated
     Transaction.

(c)  To ascertain the market prices of a replacement contract, the
     Non-Defaulting Party may consider, among other valuations, any or all of
     the settlement prices of NYMEX Power futures contracts, quotations from
     leading dealers in energy swap contracts and other bona fide third party
     offers, all adjusted for the length of the remaining term and differences
     in transmission.

(d)  It is expressly agreed that a Party shall not be required to enter into
     replacement transactions in order to determine the Termination Payment
     (defined below).

(e)  The Non-Defaulting Party shall aggregate such Gains, Losses and Costs with
     respect to all Transactions into a single net amount ("Termination
     Payment") and notify the Defaulting Party of such amount.

4.4. OBLIGATION TO PAY TERMINATION PAYMENT.

(a)  If the Non-Defaulting Party's aggregate Losses and Costs exceed its
     aggregate Gains, the Defaulting Party shall, within five (5) Business Days
     of receipt of such notice, pay such net amount to the Non-Defaulting Party,
     which amount shall bear interest at the Interest Rate from the Early
     Termination Date until paid. If the Non-Defaulting Party's aggregate Gains
     exceed its aggregate Losses and Costs, there shall be no Early Termination
     Payment.

(b)  If the Defaulting Party disagrees with the calculation of the Termination
     Payment, the issue shall be submitted to arbitration in accordance with the
     arbitration procedures set forth in Section 8.8 and the resulting
     Termination Payment shall be due and payable within three (3) Business Days
     after the award.

(c)  Notwithstanding any other provision of this Agreement, if Buyer or Seller
     fails to pay to the other Party any amounts when due, the aggrieved Party
     shall have the right to (i) suspend performance under any or all
     Transactions until such amounts plus interest at the Interest Rate have
     been paid and/or (ii) exercise any remedy available at law or in equity to
     enforce payment of such amount plus interest at the Interest Rate;
     provided, however, if the non-paying Party, in good faith, shall dispute
     the amount of any such billing or part thereof and shall pay such amounts
     as it concedes to be correct, no suspension shall be permitted.

4.5  OTHER EVENTS. If Buyer is regulated by a federal, state or local regulatory
body, and such body disallows all or any portion of any costs incurred or yet to
be incurred by Buyer under any provision of this Agreement, such

                                       4.
   5


action shall not operate to excuse Buyer from performance of any obligation nor
shall such action give rise to any right of Buyer to any refund or retroactive
adjustment of the Contract Price provided in any Transaction. Notwithstanding
the foregoing, if a Party's (the "Regulated Party") activities hereunder become
subject to regulation of any kind whatsoever under any law to a greater or
different extent than that existing on the Effective Date and such regulation
renders this Agreement illegal or unenforceable, or, as to EESI, such regulation
has the effect of limiting the price that EESI can charge for Energy under a
Transaction or otherwise materially adversely affects EESI's ability to receive
the economic benefits of a Transaction, the Regulated Party shall at such time
have the right to declare an Early Termination Date in accordance with the
provisions hereof, provided, notwithstanding the rights of the Parties to
declare an Early Termination Date as above stated, the Regulated Party shall be
liable for payment of the Termination Payment as provided in Section 4.3 as
calculated by the non-Regulated Party.

                                   SECTION 5.
                         LIMITATIONS; DUTY TO MITIGATE

5.1.  LIMITATIONS OF REMEDIES, LIABILITY AND DAMAGES.  THE PARTIES CONFIRM THAT
THE EXPRESS REMEDIES AND MEASURES OF DAMAGES PROVIDED IN THIS AGREEMENT SATISFY
THE ESSENTIAL PURPOSES HEREOF. FOR BREACH OF ANY PROVISION FOR WHICH AN EXPRESS
REMEDY OR MEASURE OF DAMAGES IS PROVIDED, SUCH EXPRESS REMEDY OR MEASURE OF
DAMAGES SHALL BE THE SOLE AND EXCLUSIVE REMEDY, THE OBLIGOR'S LIABILITY SHALL BE
LIMITED AS SET FORTH IN SUCH PROVISION AND ALL OTHER REMEDIES OR DAMAGES AT LAW
OR IN EQUITY ARE WAIVED. IF NO REMEDY OR MEASURE OF DAMAGES IS EXPRESSLY HEREIN
PROVIDED, THE OBLIGOR'S LIABILITY SHALL BE LIMITED TO DIRECT ACTUAL DAMAGES
ONLY, SUCH DIRECT ACTUAL DAMAGES SHALL BE THE SOLE AND EXCLUSIVE REMEDY AND ALL
OTHER REMEDIES OR DAMAGES AT LAW OR IN EQUITY ARE WAIVED. UNLESS EXPRESSLY
HEREIN PROVIDED, NEITHER PARTY SHALL BE LIABLE FOR CONSEQUENTIAL, INCIDENTAL,
PUNITIVE, EXEMPLARY OR INDIRECT DAMAGES, LOST PROFITS OR OTHER BUSINESS
INTERRUPTION DAMAGES, BY STATUTE, IN TORT OR CONTRACT, UNDER ANY INDEMNITY
PROVISION OR OTHERWISE. IT IS THE INTENT OF THE PARTIES THAT THE LIMITATIONS
HEREIN IMPOSED ON REMEDIES AND THE MEASURE OF DAMAGES BE WITHOUT REGARD TO THE
CAUSE OR CAUSES RELATED THERETO, INCLUDING THE NEGLIGENCE OF ANY PARTY, WHETHER
SUCH NEGLIGENCE BE SOLE, JOINT OR CONCURRENT, OR ACTIVE OR PASSIVE. TO THE
EXTENT ANY DAMAGES REQUIRED TO BE PAID HEREUNDER ARE LIQUIDATED, THE PARTIES
ACKNOWLEDGE THAT THE DAMAGES ARE DIFFICULT OR IMPOSSIBLE TO DETERMINE, OTHERWISE
OBTAINING AN ADEQUATE REMEDY IS INCONVENIENT AND THE LIQUIDATED DAMAGES
CONSTITUTE A REASONABLE APPROXIMATION OF THE HARM OR LOSS.

5.2   DUTY TO MITIGATE.  Each Party agrees that it 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 of this Agreement.

5.3   UCC.  Except as otherwise provided for herein the provisions of the
Uniform Commercial Code ("UCC") of the state whose laws shall govern this
Agreement shall be deemed to apply to all Transactions and Energy shall be
deemed to be a "good" for purposes of the UCC. EXCEPT AS EXPRESSLY SET FORTH
HEREIN, SELLER EXPRESSLY NEGATES ANY OTHER REPRESENTATION OR WARRANTY, WRITTEN
OR ORAL, EXPRESS OR IMPLIED, INCLUDING, WITHOUT LIMITATION, ANY REPRESENTATION
OR WARRANTY WITH RESPECT TO CONFORMITY TO MODELS OR SAMPLES, MERCHANTABILITY, OR
FITNESS FOR ANY PARTICULAR PURPOSE.

                                   SECTION 6.
                                BILLING; PAYMENT

6.1.   BILLING AND PAYMENT.  Seller shall render to Buyer (by regular mail,
facsimile or other acceptable means pursuant to Section 8.3) for each calendar
month during which purchases/sales are made, a statement setting forth the total
quantity of Energy that was Scheduled or that Buyer was obligated to purchase
and any other charges due

                                       5.

   6
Seller, including payments or credits between the Parties pursuant to Section
3.5 and Section 3.6, under this Agreement during the preceding month and the
amounts due to Seller from Buyer therefor. Billing and Payment will be based on
Scheduled hourly quantities. On or before five (5) days after receipt of
Seller's statement or if such day is not a Business Day, the immediately
following Business Day, Buyer shall render, by wire transfer, the amount set
forth on such statement to the payment address provided in Exhibit "A". Overdue
payments shall accrue interest from, and including, the due date to, but
excluding, the date of payment at the Interest Rate. If Buyer, in good faith,
disputes a statement, Buyer shall provide a written explanation of the basis for
the dispute and pay the portion of such statement conceded to be correct no
later than the due date. If any amount disputed by Buyer is determined to be due
to Seller, it shall be paid within ten (10) days of such determination, along
with interest accrued at the Interest Rate until the date paid.

6.2  NETTING/SETOFF. If Buyer and Seller are each required to pay an amount in
the same month, then such amounts with respect to each Party may be aggregated,
and the Parties may discharge their obligations to pay through netting, in which
case the Party, if any, owing the greater aggregate amount may pay to the other
Party the difference between the amounts owed. Each Party reserves to itself all
rights, setoffs, counterclaims and other remedies and defenses consistent with
Section 5 (to the extent not expressly herein waived or denied) which such Party
has or may be entitled to arising from or out of this Agreement. All outstanding
Transactions and the obligations to make payment in connection therewith or
under this Agreement or any other agreement between the Parties may be offset
against each other, set off or recouped therefrom.

6.3. AUDIT. Each Party (and its representative(s)) has the right, at its sole
expense and during normal working hours, to examine the records of the other
Party to the extent reasonably necessary to verify the accuracy of any
statement, charge or computation made pursuant to this Agreement. If requested,
a Party shall provide to the other Party statements evidencing the quantities of
Energy delivered at the Delivery Point. If any such examination reveals any
inaccuracy in any statement, the necessary adjustments in such statement and the
payments thereof will be promptly made and shall bear interest calculated at the
Interest Rate from the date the overpayment or underpayment was made until paid;
provided, however, that no adjustment for any statement or payment will be made
unless objection to the accuracy thereof was made prior to the lapse of two
years from the rendition thereof; and provided further that this agreement will
survive any termination of the Agreement for a period of two years from the date
of such termination for the purpose of such statement and payment objections. If
any adjustment owed by a Party determined pursuant to this provision is in
excess of $10,000, the audited Party will be responsible for the auditing
Party's expenses, up to a maximum of $5,000. Further, the Parties agree that
each may audit the other a maximum of one time per year during the Master Term,
or any extension thereof.

                                   SECTION 7.
                                     TAXES

7.1  TAXES. The Contract Price shall include full reimbursement for, and Seller
is liable for and shall pay, or cause to be paid, or reimburse Buyer if Buyer
has paid, all Taxes applicable to a Transaction arising prior to the Delivery
Point. If Buyer is required to remit such Tax, the amount shall be deducted from
any sums due to Seller. Seller shall indemnify, defend and hold harmless Buyer
from any Claims for such Taxes. The Contract Price does not include
reimbursement for, and buyer is liable for and shall pay, cause to be paid, or
reimburse Seller if Seller has paid, all Taxes applicable to a Transaction
arising at and from the Delivery Point, including any Taxes imposed or collected
by a taxing authority with jurisdiction over Buyer. Buyer shall indemnify,
defend and hold harmless Seller from any Claims for such Taxes. Either Party,
upon written request of the other, shall provide a certificate of exemption or
other reasonably satisfactory evidence of exemption if either Party is exempt
from taxes, and shall use reasonable efforts to obtain and cooperate with
obtaining any exemption from or reduction of any Tax. Each Party shall use
reasonable efforts to administer this Agreement and implement the provisions in
accordance with the intent to minimize Taxes.

7.2. NEW TAXES. If (i) a New Tax is imposed and (ii) Customer or EESI would be
responsible for paying such New Tax with respect to the Transactions, the Party
responsible for the New Tax ("Affected Party") shall be entitled to declare an
Early Termination Date with respect to those Transactions affected by the New
Tax ("Affected Transactions") in accordance with the provisions of this
Agreement subject to the following conditions:



                                       6.
   7
(a) the Affected Party must give the other Party ("Non-Affected Party") at least
thirty (30) days prior written notice of its intent to declare an Early
Termination Date (which notice shall also include the additional information
described in the last sentence of this Section 7.2), and prior to the proposed
Early Termination Date, Customer and EESI shall attempt to reach a mutual
agreement as to which Party will pay the New Tax, (b) if a mutual agreement is
not reached within thirty (30) days after the Affected Party provides the notice
provided in subsection (a) above, the Early Termination Date shall take effect
and all Affected Transactions shall be terminated and be subject to the same
Early Termination Date, (c) the Early Termination Date shall be effected as if
an Event of Default had occurred and EESI shall calculate in a commercially
reasonable manner its net Loss (amount of Losses and Costs after netting Gains),
if any, resulting from the termination of all Affected Transactions as if it
were the "Non-Defaulting Party" under Section 4 hereof and provided further that
EESI's Gains and Losses shall be determined without taking into effect the
impact of the New Taxes, and (d) Customer shall pay to EESI the amount of the
net Loss calculated in subsection (c) above in accordance with the provisions of
Section 4.4(a). In the notice described in subsection (a) above the Affected
Party will include a calculation, in reasonable detail, estimating the notional
value of the amount payable under subsection (c) above, the Parties acknowledge
that such calculation shall be merely a good faith estimate of the amount
payable and a final and definitive calculation of the amount due will be made on
or before the Early Termination Date.

                                   SECTION 8.
                                 MISCELLANEOUS

8.1. ASSIGNMENT.  Neither Party shall assign this Agreement or its rights
hereunder without the prior written consent of the other Party, which consent
may be withheld in its sole discretion; provided, however, either Party may,
without the consent of (but with notice to) the other Party (and without
relieving itself from liability hereunder), (i) transfer, sell, pledge, encumber
or assign this Agreement or the accounts, revenues or proceeds hereof in
connection with any financing or other financial arrangements, (ii) transfer or
assign this Agreement to an Affiliate of such Party, or (iii) transfer or assign
this Agreement to any person or entity succeeding to all or substantially all of
the assets of such Party; provided, however, that in each such case, any such
assignee shall agree to in writing to be bound by the terms and conditions
hereof.

8.2. FINANCIAL INFORMATION.  If requested by Customer, EESI shall deliver (i)
within 120 days following the end of each fiscal year, a copy of the annual
report of Enron Corp. containing audited consolidated financial statements for
such fiscal year certified by independent certified public accountants and (ii)
within 60 days after the end of each of its first three fiscal quarters of each
fiscal year, a copy of the quarterly report of Enron Corp. containing unaudited
consolidated financial statements for such fiscal quarter. If requested by EESI,
Customer shall deliver (i) within 120 days following the end of each fiscal
year, a copy of the annual report of Customer containing audited consolidated

intention of the Parties. Notwithstanding the foregoing, or anything else in the
Agreement to the contrary, in the event that, as a result of a Regulatory Event,
a Party (the "Excused Party") is excused from any payment or performance
obligation, the other Party shall be correspondingly excused from any payment or
performance obligation that would have arisen but for the failure or inability
of the Excused Party to perform. The term "including" when used in this

to be in limitation. The headings used herein are for convenience and reference
purposes only.

nature, whether such Claims sound in contract, tort, or otherwise, at law or
in equity, under state or federal law, whether provided by statute or the common
law, for damages or any other relief, shall be resolved by binding arbitration.
Arbitration shall be conducted in accordance with the rules of arbitration of
the Federal Arbitration Act and, to the extent an issue is not addressed by the
federal law on arbitration, by the Commercial Arbitration Rules of the American

recover any such damages. The arbitration proceeding shall be conducted in
Phoenix, AZ. Within thirty days of the notice of initiation of the arbitration

select a third arbitrator. The third arbitrator shall be a person who has over
eight years professional experience in electrical energy-related transactions
and who has not previously been employed by either Party and does not have a
direct or indirect interest in either Party or the subject matter of the
arbitration. While the third arbitrator shall be neutral, the two
party-appointed arbitrators are not required to be neutral, and it shall not be
grounds for removal of either of the two party-appointed arbitrators or for
vacating the arbitrators' award that either of such arbitrators has past or
present relationships with the Party that appointed such arbitrator. To the
fullest extent permitted by law, any arbitration proceeding and the arbitrators
award shall be maintained in confidence by the Parties.
