                  NOTES TO THE CONDENSED FINANCIAL STATEMENTS

                                  (UNAUDITED)

1.  BASIS OF PRESENTATION

     We are a single member Delaware limited liability company organized in May
2001, under the terms of a limited liability company agreement. We are a wholly
owned direct subsidiary of Mesquite Investors, L.L.C., an entity which is
indirectly owned by the Limestone Electron Trust and a subsidiary of El Paso
Corporation. Our sole business is to sell electric energy and provide electric
capacity to Public Service Electric and Gas Company, a New Jersey corporation,
under an amended power purchase agreement that we entered into with Public
Service Electric. We began operating under this amended power purchase agreement
on December 13, 2001.

     We prepared this Quarterly Report on Form 10-Q under the rules and
regulations of the United States Securities and Exchange Commission. Because
this is an interim period filing presented using a condensed format, it does not
include all of the disclosures required by generally accepted accounting
principles. You should read it along with our December 31, 2001 audited
financial statements as presented in the amendment to our registration statement
on Form S-4 which includes a summary of our significant accounting policies and
other disclosures. The financial statements as of September 30, 2002, and for
the quarter and nine months ended September 30, 2002, are unaudited. We derived
the balance sheet as of December 31, 2001, from the audited balance sheet filed
in our amendment to our registration statement on Form S-4. We believe we have
made all adjustments, all of which are of a normal, recurring nature, to fairly
present our interim period results. Due to the seasonal nature of our business,
information for interim periods may not necessarily indicate the results of
operations for the entire year.

     Our accounting policies are consistent with those discussed in our
amendment to our registration statement on Form S-4, except as discussed below.

  Deferred Financing Costs

     Our deferred financing costs represent the cost to issue our bonds and are
being amortized using the effective-interest method over the term of the bonds.
During the nine months ended September 30, 2002, we incurred an additional $0.5
million of deferred financing costs related to the exchange of our 9.875% Series
A Senior Secured Bonds for registered 9.875% Series B Senior Secured Bonds.
Amortization of deferred financing costs was approximately $0.7 million for the
nine months ended September 30, 2002 and is included in our statement of
operations as interest and debt expense.

  Accounting for Amended Power Purchase and Mirror Power Purchase Agreements

     We record our amended power purchase and mirror power purchase agreements
on our balance sheet at their estimated fair values in accordance with Statement
of Financial Accounting Standards (SFAS) No. 133, Accounting for Derivative
Instruments and Hedging Activities, as amended. We estimate the fair value of
our amended power purchase agreement with Public Service Electric and our mirror
power purchase agreement with El Paso Merchant Energy, L.P., our affiliate,
based on an estimate of the cash receipts and payments under these agreements
using anticipated future power prices compared to the contractual prices under
these agreements, discounted at a rate that is based upon the 10-year United
States Treasury rate, adjusted for the credit risk of each counterparty. We make
adjustments to this discount rate when we believe that market changes in the
rates result in changes in fair values that can be realized. We consider whether
changes in the rates are the result of changes in the capital markets, or are
the result of sustained economic changes. During the third quarter treasury
rates declined. We did not adjust our discount rate for this decline in treasury
rates since this decrease, combined with the significant uncertainties in the
capital markets, did not result in an increased fair value that we believe could
have been realized in the market. As of September 30, 2002, the discount rate
used to calculate the fair value of the amended power purchase agreement was
7.02 percent and the rate used to calculate the fair value of the mirror power
purchase agreement was 7.77 percent.

                                        4
<PAGE>

     Our estimates of the timing of cash receipts and payments are based on the
anticipated timing of power delivered under these agreements. These estimates
also consider the minimum and maximum energy delivery requirements under our
agreements. Estimates of the future prices of power are based on the forward
pricing curve of the appropriate power delivery and receipt points, and this
curve is derived from actual prices observed in the market, price quotes from
brokers and extrapolation models that rely on actively quoted prices and
historical information. Changes in these values in the future, which could be
positive or negative, will occur as our estimates of each of these variables
change and as additional market data becomes available, and these changes could
be material from period to period. However, the pricing of our power agreements
is fixed over their term and, as a result, despite short-term fluctuations in
market factors, our long-term reported results will be more reflective of the
terms of these agreements. If significant future changes in interest rates or
counterparty credit risks occur, it will have a significant impact on our
financial position and results of operations.

NEW ACCOUNTING PRONOUNCEMENTS

  Goodwill and Other Intangible Assets

     In July 2001, the Financial Accounting Standards Board (FASB) issued SFAS
No. 142, Goodwill and Other Intangible Assets. This standard requires that
goodwill no longer be amortized but periodically tested for impairment, at least
on an annual basis, or whenever an event occurs to indicate that an impairment
may have occurred. Other intangible assets are to be amortized over their useful
life and reviewed for impairment in accordance with the provisions of SFAS No.
144, Accounting for the Impairment or Disposal of Long-Lived Assets. An
intangible asset with an indefinite useful life can no longer be amortized until
its useful life becomes determinable. This statement has various effective
dates, the most significant of which is January 1, 2002. The adoption of this
standard on January 1, 2002 did not have a material effect on our financial
statements.

NEW ACCOUNTING PRONOUNCEMENTS ISSUED BUT NOT YET ADOPTED

  Reporting Gains and Losses from the Early Extinguishment of Debt

     In April 2002, the FASB issued SFAS No. 145, Rescission of FASB Statements
No. 4, 44, and 64, Amendment of FASB Statement No. 13, and Technical
Corrections. This statement addresses how to report gains or losses resulting
from the early extinguishment of debt. Under current accounting rules, any gains
or losses on early extinguishment of debt are reported as an extraordinary item.
When we adopt SFAS No. 145, we will be required to evaluate whether the debt
extinguishment is truly extraordinary in nature. If we routinely extinguish debt
early, the gain or loss will be included in income from continuing operations.
This statement will be effective for our 2003 year-end reporting.

  Accounting for Costs Associated with Exit or Disposal Activities

     In July 2002, the FASB issued SFAS No. 146, Accounting for Costs Associated
with Exit or Disposal Activities. This statement will require us to recognize
costs associated with exit or disposal activities when they are incurred rather
than when we commit to an exit or disposal plan. Examples of costs covered by
this guidance include lease termination costs, employee severance costs that are
associated with a restructuring, discontinued operations, plant closings, or
other exit or disposal activities. The provisions of this statement are
effective for fiscal years beginning after December 31, 2002 and will impact any
exit or disposal activities initiated after January 1, 2003.

2.  COMMITMENTS AND CONTINGENCIES

  Amended Power Purchase Agreement

     We have an amended power purchase agreement with Public Service Electric
that extends through March 5, 2013. Under the amended power purchase agreement,
we sell and deliver electric energy to Public Service Electric at established
prices and delivery points within the Pennsylvania-New Jersey-Maryland power
system. Additionally, we are required to arrange for 189 megawatts per day of
capacity through October 31, 2008 and 149 megawatts per day of electric capacity
from November 1, 2008 through the end of the

                                        5
<PAGE>

agreement to be made available to Public Service Electric. The prices under the
agreement are specified on an annual basis and escalate each year over the
contract term beginning in 2003. The price is $80.88 per megawatt hour (MWh) in
2002, $77.75 per MWh in 2003, and increases annually thereafter to $105.42 per
MWh in 2013. Annual energy deliveries cannot exceed the specified maximum
amounts, which range from 1,501,825 MWh in 2002 to 1,171,424 MWh in 2012 and
205,400 MWh in 2013.

     If we fail to deliver all or part of the scheduled energy or fail to
schedule sufficient deliveries to meet the minimum energy deliveries for reasons
within our control, Public Service Electric's payment to us may be reduced by a
credit as specified in the amended power purchase agreement, if any, for energy
purchased by Public Service Electric over the prices stated in our amended power
purchase agreement. No credits were applied during the nine months ended
September 30, 2002.

     If we fail to provide all or part of the required electric capacity for
reasons within our control, Public Service Electric must use reasonable efforts
to purchase replacement capacity in the amount of the shortfall. We must
reimburse Public Service Electric for all costs associated with the replacement
capacity. If Public Service Electric is unable to replace this capacity
shortfall, Public Service Electric's payment to us will be reduced by a credit
as specified in the amended power purchase agreement. Generally, the credit
would equal the deficiency charge, if any, payable by Public Service Electric as
a direct result of our failure to provide the required electric capacity. No
credits were applied during the nine months ended September 30, 2002.

  Mirror Power Purchase Agreement

     In order to meet our electric energy delivery and electric capacity
commitments under the amended power purchase agreement, we entered into a mirror
power purchase agreement with El Paso Merchant. The mirror power purchase
agreement has the same term as the amended power purchase agreement. Under this
agreement, we purchase energy at an established price and at quantities
sufficient to meet our obligations to Public Service Electric. The established
price under the mirror power purchase agreement is $32.00 per MWh for the term
of the contract.

     Under the mirror power purchase agreement, El Paso Merchant must schedule
and deliver to us during each year both the minimum hourly electric energy
deliveries and the full amount of electric energy deliveries that we are
obligated to deliver under our amended power purchase agreement with Public
Service Electric and El Paso Merchant must make available to us capacity credits
equal to the electric capacity we are required to provide under our amended
power purchase agreement with Public Service Electric. If El Paso Merchant fails
to deliver all or part of the scheduled energy to us for any reason within their
control, our payment to El Paso Merchant will be reduced by a credit calculated
in the same manner as the credit to Public Service Electric described above. No
credits were taken during the nine months ended September 30, 2002. El Paso
Merchant's performance under this agreement has been guaranteed by El Paso
Corporation under a performance guaranty.

     If El Paso Merchant fails in any month to provide all or part of the
capacity, for any reason within their control, our payment to El Paso Merchant
will be reduced by a credit calculated in the same manner as the credit to
Public Service Electric as a direct result of our failure to provide capacity
under the amended power purchase agreement. No credits were taken during the
nine months ended September 30, 2002.

     Because our amended power purchase and mirror power purchase agreements are
similar in terms of the amount of capacity provided and the quantities of energy
bought and sold, and since prices under these agreements are established, the
execution of these agreements results in our ability to receive a determinable
cash margin over the term of the agreements. Assuming that minimum energy
delivery requirements are met and all capacity requirements are made available,
this margin will range from $45.75 to $73.42 per MWh sold over the remaining
life of the agreements.

3.  RELATED PARTY TRANSACTIONS

  Mirror Power Purchase Agreement

     El Paso Merchant provides electric energy and electric capacity to us under
the mirror power purchase agreement as discussed above. Purchases under this
agreement are based on market rates at the time the agreement was negotiated.
Total purchases during 2002 are reflected as electricity purchases -- affiliate
in our statements of operations. Amounts owed under the agreement are included
in our accounts payable -- affiliate on our balance sheets.

  Administrative Services Agreement

     We have an administrative services agreement with El Paso Merchant to
provide project management, finance and accounting services to us for a fee of
$100,000 per year through 2013. In addition to the base fee, we are obligated to
reimburse El Paso Merchant for direct expenses other than project management,
finance and accounting services that may be incurred on our behalf. Fees and
expenses under this agreement are due and payable only to the extent that we
have sufficient cash after paying obligations under our bond indenture. Total
fees incurred under this agreement during 2002 are reflected as administrative
fees to affiliate in our statements of operations.

  El Paso Corporation Performance Guaranty

     El Paso Corporation, the parent company of El Paso Merchant, entered into a
performance guaranty with us on December 12, 2001, which expires after the
expiration of El Paso Merchant's obligations under the mirror power purchase and
administrative services agreements. Under the performance guaranty, El Paso
Corporation guarantees to us the punctual performance of all of El Paso
Merchant's obligations under the mirror power purchase agreement and the
administrative services agreement.

  Distributions

     As permitted by our senior secured bond indenture and our limited liability
company agreement, cash distributions may be made to our member bi-annually
starting September 1, 2002 for all excess cash, provided that no event of
default or defaults have occurred, and the debt coverage ratio calculated as of
that date for the most recently ended six-month period equals or exceeds 1.03 to
1.00. A distribution of $8.5 million was paid to our member during September
2002.

  El Paso Corporation Announces Exit of Energy Trading Activities

     On November 8, 2002, El Paso Corporation announced their plan to exit the
energy trading business. El Paso's plan includes forming a new subsidiary to
hold, manage and liquidate their trading assets and liabilities previously held
by their 100% owned subsidiary and our affiliate, El Paso Merchant Energy, L.P.
Our indenture requires the consent of our bondholders to an assignment by El
Paso Merchant of its obligations under our mirror power purchase agreement. El
Paso Corporation has guaranteed to us the punctual performance of all of El Paso
Merchant's obligations under the mirror power purchase and administrative
services agreements. We are in the process of evaluating what impact, if any,
that this announcement will have on these agreements.

4.  FAIR VALUE OF FINANCIAL INSTRUMENTS

     As of September 30, 2002 and December 31, 2001, the carrying amounts of our
financial instruments including cash, cash equivalents and trade receivables and
payables are representative of fair value because of their short-term nature.
The fair value of our long-term debt was $349.2 million as of September 30,
2002, and $432.0 million as of December 31, 2001. The fair value of our
long-term debt has been estimated based on quoted market prices for the same or
similar issues.

     In May 2002, Standard and Poor's lowered the senior unsecured credit rating
of our only customer, Public Service Electric, from BBB+ to BBB-. Although our
credit rating is not directly related to the credit
                                        7
<PAGE>

rating of Public Service Electric, an indirect result of this downgrade was a
reduction in the credit rating of our bonds in June 2002 by Standard and Poor's
from BBB to BBB-. Further downgrades of Public Service Electric could indirectly
have a negative impact on the fair value of our long-term debt.

     On October 4, 2002, Moody's Investors Service downgraded our debt rating to
Baa3 from Baa2. This downgrade reflects previous action taken by Moody's on the
ratings of El Paso Corporation which guarantees El Paso Merchant's performance
under our mirror power purchase agreement. On November 12, 2002, action was
taken by Standard and Poor's which resulted in a downgrade to El Paso
Corporation's credit ratings. This and further downgrades of El Paso
Corporation's credit ratings could indirectly have a negative impact on the fair
value of our long-term debt.

Potential Change in Mesquite Investors' Ownership

     On November 8, 2002, El Paso Corporation announced its intent to acquire an
additional interest in Chaparral Investors, L.L.C. Chaparral owns Mesquite
Investors, L.L.C., our parent company. Chaparral is owned approximately 20% by
El Paso and the remainder by Limestone Investors, L.L.C. If El Paso acquires
Limestone's interests, we would become a wholly-owned, indirect subsidiary of El
Paso.

GENERAL

Power Contract Restructurings

     Our sole business is to sell electric energy and provide electric capacity
to Public Service Electric under our amended power purchase agreement with them.
We were formed in May 2001, but did not begin operations until December 13, 2001
when the Cogen Technologies NJ Venture, or Bayonne, power purchase agreement
with Public Service Electric and the Camden Cogen, L.P., or Camden, power
purchase agreement with Public Service Electric were contributed to us by our
member. The amended power purchase agreement combined and superseded the Bayonne
and Camden power purchase agreements with Public Service Electric. The
contribution of these power purchase agreements to us was a part of the process
that has become known in the power industry as a "power contract restructuring."
Many domestic power plants have long-term power purchase agreements with
regulated utilities that were entered into under the Public Utility Regulatory
Policies Act of 1978 (PURPA). The power sold to the utility under these PURPA
contracts is required to be delivered from a specified power generation plant at
power prices that are usually significantly higher than the cost of power in the
wholesale power market. The cost of generating power at these PURPA power plants
is typically higher than the cost that would be incurred by obtaining the power
in the wholesale power market, principally because the PURPA power plants are
less efficient than newer power generation facilities.

     In a power contract restructuring, the PURPA power purchase agreement is
amended so that the power sold to the utility does not have to be provided from
the specific power plant. Because we are able to buy lower cost power in the
wholesale power market, we have the ability to reduce the cost paid by the
utility, thereby inducing the utility to enter into the power contract
restructuring transaction. Following the contract restructuring, the power plant
operates on a merchant basis, which means that it is no longer dedicated to one
buyer and will operate only when power prices are high enough to make operations
economical. Prior to a power contract restructuring, the power plant and its
related PURPA power purchase agreement are accounted for at their historical
cost, which is either the cost of construction or, if acquired, the acquisition
cost. Revenues and expenses prior to restructuring are, in most cases, accounted
for on an accrual basis as power is generated and sold to the utility. As part
of the restructuring, any related fuel supply and steam agreements are generally
amended or terminated, the value of the remaining merchant plant is evaluated
for possible impairment, and the restructured power agreements are adjusted to
their estimated fair value. The
                                        9
<PAGE>

restructured power purchase agreement can then be sold or we can enter into an
offsetting, or mirror, power purchase agreement. In cases when we enter into a
mirror power purchase agreement, we use the restructured agreement and the
mirror power purchase agreement along with the fixed-price spread between these
agreements as collateral to obtain financing. The offsetting power purchase
agreement requires the power supplier, which can be an affiliate or third-party,
to provide long-term fixed price power in amounts sufficient for us to meet our
obligations under the restructured power agreements.

     Under the pre-existing power purchase agreements, Bayonne and Camden sold
generating capacity and associated energy from the Bayonne and Camden facilities
to Public Service Electric and the Bayonne and Camden facilities were required
to be qualifying facilities under PURPA. The Bayonne power purchase agreement
and the Camden power purchase agreement each required that the sellers under the
respective agreements source capacity and energy only from their respective
facilities. The amended power purchase agreement eliminated the requirement that
the Bayonne facility and the Camden facility be the only sources of energy
provided under that agreement. The elimination of this requirement benefited us
because now we can source energy from any source connected to the
Pennsylvania-New Jersey-Maryland (PJM) market, and the cost of energy sourced in
this manner may be less expensive than the cost to produce such energy at the
Bayonne or Camden facilities. The benefits of the amended power purchase
agreement also include significantly more flexibility in scheduling energy
deliveries, including a greater degree of daily delivery flexibility. From the
perspective of Public Service Electric, our ability to source lower cost power
in the market allowed us to provide Public Service Electric with a benefit in
the form of a payment from us of $64.0 million when the restructured power
purchase agreement became effective.

     Through a series of transactions, the pre-existing power purchase
agreements were distributed to our member who, in turn, contributed them to us
on December 12, 2001 at a book value of $299.1 million. We subsequently combined
and amended the pre-existing power purchase agreements and began operating under
our amended power purchase agreement on December 13, 2001. In order to meet our
energy delivery and electric capacity commitments under the amended power
purchase agreement, we entered into a mirror power purchase agreement with El
Paso Merchant. The mirror power purchase agreement has the same term as the
amended power purchase agreement and we purchase energy at an established price
and at quantities sufficient to meet our obligations to Public Service Electric.

     In December 2001, we issued 9.875% Series A Senior Secured Bonds, due 2013,
with an aggregate principal amount of $431.4 million at a discount of $6.4
million. We completed an exchange of the Series A bonds for registered 9.875%
Series B Senior Secured Bonds, due 2013, on July 31, 2002. The terms of the
Series B bonds and the Series A bonds are substantially the same in all material
respects, except that the Series B bonds are registered with the Securities and
Exchange Commission. Scheduled payments of principal and interest on the bonds
will be paid from the positive margin created between the sales of electric
energy and capacity to Public Service Electric and purchases of electric energy
and capacity from El Paso Merchant.

     We account for our amended power purchase agreement and our mirror power
purchase agreement as derivative instruments under the provisions of SFAS No.
133, Accounting for Derivative Instruments and Hedging Activities, as amended.
As a result, the amended power purchase agreement and the mirror power purchase
agreement are recorded on our balance sheet at their estimated fair values. We
reflected the difference between the book value of these agreements and their
estimated market value at December 13, 2001 as a gain of $228.2 million in our
2001 statement of income.

     As of September 30, 2002, these agreements had an estimated net fair value
of $565.1 million. For the nine months ended September 30, 2002, the change in
estimated net fair value of these agreements was a decrease of $24.0 million and
was recorded as a component of operating expenses in our condensed statement of
operations. The fair values of these agreements are calculated based on expected
cash receipts and payments under the agreements compared to the estimated future
market prices of power. These estimated market prices for power consider a
combination of available market data, broker quotations and models that are
derived based on historical market prices. The differences between market and
contractual prices are then discounted using discount rates that consider the
counterparty credit risk and current and anticipated market conditions.

                                        10
<PAGE>

     We make adjustments to this discount rate when we believe that market
changes in the rates result in changes in fair values that can be realized. We
consider whether changes in the rates are the result of changes in the capital
markets, or are the result of sustained economic changes. During the third
quarter treasury rates declined. We did not adjust our discount rate for this
decline in treasury rates since this decrease, combined with the significant
uncertainties in the capital markets, did not result in an increased fair value
that we believe could have been realized in the market. As of September 30,
2002, the discount rate used to calculate the fair value of the amended power
purchase agreement was 7.02 percent and the rate used to calculate the fair
value of the mirror power purchase agreement was 7.77 percent.

     We also adjust our valuations for factors such as market liquidity, market
price correlation and model risk, as needed. Future power prices are based on
the forward pricing curve of the appropriate power delivery and receipt points
in the applicable power market. This forward pricing curve is derived from a
combination of actual prices observed in the applicable market, price quotes
from brokers and extrapolation models that rely on actively quoted prices and
historical information. The timing of cash receipts and payments are based on
the expected timing of power delivered under these contracts.

RESULTS OF OPERATIONS

     We were formed in May 2001, but did not begin operations until December 13,
2001 when we began operating under the amended power purchase agreement with
Public Service Electric and Gas Company. As a result, our discussion of
financial condition and results of operations only encompasses those periods in
which we had operations.

Quarter Ended September 30, 2002

     For the quarter ended September 30, 2002, we had a net loss of $0.5
million. During the third quarter of 2002, we generated operating revenues of
$33.1 million from the sale of approximately 409,000 megawatt hours of electric
energy, and from providing electric capacity to Public Service Electric. Our
operating expenses totaled approximately $22.6 million, and were comprised
primarily of payments to El Paso Merchant for purchases of energy of $13.1
million, and a decrease in the fair value of our power agreements of $9.5
million. Our operating expenses also include fees incurred under our
administrative services agreement with El Paso Merchant. Interest and debt
expense for the period was $11.1 million.

Nine Months Ended September 30, 2002

     For the nine months ended September 30, 2002, we had a net loss of $2.8
million. During the first nine months of 2002, we generated operating revenues
of $89.5 million from the sale of approximately 1,107,000 megawatt hours of
electric energy and from providing electric capacity to Public Service Electric.
Our operating expenses for the first nine months of 2002 were $59.5 million and
include purchases of electric energy from El Paso Merchant of $35.4 million and
a decrease in the fair value of our power agreements of $24.0 million. Our
operating expenses also include fees incurred under our administrative services
agreement with El Paso Merchant. Interest and debt expense for the nine months
ended September 30, 2002 was $33.3 million.

LIQUIDITY AND CAPITAL RESOURCES

Cash from Operating Activities

     Net cash provided by operating activities was $26.6 million for the nine
months ended September 30, 2002 and was derived primarily from electric energy
and electric capacity sales to Public Service Electric net of electricity
purchases, other operating expenses and cash paid for interest, offset by
working capital changes created by the timing of payments made and received.

                                        11
<PAGE>

Cash from Financing Activities

     Net cash used in financing activities was $14.8 million for the nine months
ended September 30, 2002 and consisted primarily of a $5.8 million principal
payment on our long-term debt, and an $8.5 million distribution to our member in
September 2002.

Distributions and Debt Service

     Under our bond indenture, cash distributions may be made to our member
bi-annually starting September 1, 2002 for all excess cash, provided that no
event of default or defaults have occurred, and the debt coverage ratio
calculated as of that date for the most recently ended six-month period equals
or exceeds 1.03 to 1.00. In September 2002, we distributed $8.5 million to our
member in accordance with the terms of our bond indenture and our limited
liability company agreement. During the six months ended August 31, 2002, we
generated funds of $35.2 million available for debt service from the sale of
electric energy and electric capacity. Interest for the period was approximately
$21.3 million, providing an interest coverage ratio of 1.65. Including
proportionate principal payments for the same period of approximately $4.1
million, the debt service ratio was 1.39. During the nine months ended September
30, 2002, we generated funds of approximately $54.4 million available for debt
service from the sale of electric energy and electric capacity. Interest for
this period was approximately $31.9 million, providing an interest coverage
ratio of 1.71. Including the proportionate principal payments for the same
period of approximately $7.5 million, this debt service coverage ratio was 1.38.

ITEM 3.  QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

INTEREST RATE RISK

     We are exposed to changing interest rates. The table below shows the
carrying amounts and weighted average interest rates of our interest bearing
debt, by expected maturity date. The fair value of our fixed rate long-term debt
was estimated based on quoted market prices for the same or similar issues.

     On October 4, 2002, Moody's Investor Service downgraded our debt rating to
Baa3 from Baa2. This downgrade reflects previous action taken by Moody's on the
rating of El Paso Corporation which guarantees El Paso Merchant's performance
under our mirror power purchase agreement. On November 12, 2002, action was
taken by Standard and Poor's which resulted in a downgrade to El Paso
Corporation's credit ratings. This and further downgrades of El Paso
Corporation's credit ratings could indirectly have a negative impact on the fair
value of our long-term debt.

     Our power contracts are also sensitive to interest rates since the
anticipated cash flows from these contracts are discounted at a credit
risk-adjusted United States Treasury rate to arrive at their fair value. Changes
in these rates impact our fair value estimates. The sensitivity of the fair
value of our power agreements to changes in interest rates are as follows:

COMMODITY PRICE RISK

     Our amended power purchase agreement and mirror power purchase agreement
meet the definition of derivatives under the provisions of SFAS No. 133 and are
carried at their fair value. The fair value of these

                                        13

agreements at September 30, 2002, was estimated considering the expected
estimated cash receipts and payments under these agreements using contractual
prices under these agreements compared to anticipated future power prices,
discounted at a risk-adjusted rate commensurate with the term of each contract
and the credit risk of the counterparty. Our estimates of the timing of cash
receipts and payments are based on the anticipated timing of power delivery
under these agreements. These estimates also consider the minimum and maximum
energy delivery requirements under those agreements. Estimates of the future
prices of power consider the forward pricing curve of the appropriate power
delivery and receipt points, and this curve is derived from the actual prices
observed in the market, price quotes from brokers and extrapolation models that
rely on actively, quoted prices and historical information. Changes in future
prices impact the fair value of these contracts.

     The sensitivity of the fair value of our power agreements to changes in
commodity prices is as follows:

ITEM 4.  CONTROLS AND PROCEDURES

     Under the supervision and with the participation of our management,
including our principal executive officer and principal financial officer, we
have evaluated the effectiveness of the design and operation of our disclosure
controls and procedures within 90 days of the filing date of this quarterly
report, pursuant to Rules 13a-15 and 15d-15 under the Securities Exchange Act of
1934 (the "Exchange Act"). Based on that evaluation, our principal executive
officer and principal financial officer have concluded that these controls and
procedures are effective. There were no significant changes in our internal
controls or in other factors that could significantly affect these controls
subsequent to the date of their evaluation.

     Disclosure controls and procedures are our controls and other procedures
that are designed to ensure that information required to be disclosed by us in
the reports that we file or submit under the Exchange Act is recorded,
processed, summarized and reported, within the time periods specified under the
Exchange Act. Disclosure controls and procedures include, without limitation,
controls and procedures designed to ensure that information required to be
disclosed by us in the reports that we file under the Exchange Act is
accumulated and communicated to our management, including our principal
executive officer and principal financial officer, as appropriate to allow
timely decisions regarding required disclosure.

     The principal executive officer and principal financial officer
certifications required under Sections 302 and 906 of the Sarbanes-Oxley Act of
2002 have been included herein, or as Exhibits to this Quarterly Report on Form
10-Q, as appropriate.
