                        CAMDEN POWER MARKETING AGREEMENT


         THIS CAMDEN POWER MARKETING AGREEMENT (the "Agreement"), made and
entered into this 1st day of October, 2001, by and between EL PASO MERCHANT
ENERGY, L.P. ("Marketer") and MESQUITE INVESTORS, L.L.C., a Delaware limited
liability company ("Mesquite"). Marketer and Mesquite are hereafter sometimes
referred to individually as a "Party" and collectively as the "Parties."

                              W I T N E S S E T H:

         WHEREAS, Camden Cogen L.P. (the "Company") owns a natural gas-fired
combined cycle electric generation facility having a nominal capacity of
approximately 143 MW located in Camden, New Jersey (the "Facility");

         WHEREAS, Marketer is a power marketer engaged in the purchase, sale and
marketing of electric energy and capacity;

         WHEREAS, Marketer and Company have entered into the Camden Power
Purchase/Sale Transaction Confirmation, dated as of the date hereof, pursuant to
which Marketer has agreed to purchase Energy from the Company as provided
therein (the "Camden Transaction Confirmation");

         WHEREAS, Mesquite desires to induce Marketer to enter into the Camden
Transaction Confirmation; and

         WHEREAS, the Parties desire to set forth certain terms and conditions
applicable to such management of the purchases and sales of the Power of the
Facility pursuant to the Camden Transaction Confirmation.

         NOW, THEREFORE, in consideration of the mutual agreements, covenants
and conditions herein contained, the Parties agree as follows:

                                    ARTICLE I
                         DEFINITIONS AND INTERPRETATIONS

         1.1 Definitions - Unless otherwise provided to the contrary in this
Agreement, capitalized terms in this Agreement shall have the meanings set forth

         1.2 Interpretations - Unless expressly provided to the contrary in this

                                   ARTICLE II
                           PURCHASE AND SALE OF POWER

         2.1 Marketing Obligation - Subject to the other provisions of this
Agreement, Marketer shall be obligated to use all commercially reasonable
efforts to schedule Power under the Camden Transaction Confirmation and to sell
all of the available Power made available to it under the Camden Transaction
Confirmation in a manner to maximize the net revenues obtained for the sale of
such Power.

         2.2 Terms and Conditions for all Sales - The terms and conditions
applicable to sales of Power shall be in accordance with the provisions of the
PJM Agreement and the contracts entered into by parties pursuant to the PJM
Agreement for the sale of Power ("PJM Contracts"), as such agreement and
contracts may change from time to time.

                  (a) Limitation of Liability - The Parties acknowledge that the
market for the purchase and sale of Power is often a volatile and fluctuating
market and that, despite use of commercially reasonable efforts, Marketer may
not always obtain the maximum net revenues for the Power.

         2.3 Negotiation of Bilateral Contracts - Marketer shall use all
commercially reasonable efforts to identify opportunities for the sale of the
Power purchased by Marketer from Company under the Camden Transaction
Confirmation pursuant to Bilateral Contracts with third parties that Marketer
believes would be on terms more favorable than selling the Power under short
term arrangements. Depending on the term of the proposed Bilateral Contract, the
Parties agree as follows:

                  (a) Long-Term Bilateral Contracts - With regard to any
proposed Bilateral Contract with a term of three (3) months or more ("Long-Term
Bilateral Contract"), Marketer shall submit such Long-Term Bilateral Contract
opportunity to Mesquite for its review and approval. Marketer shall provide all
information that is reasonably requested by Mesquite to assist in Mesquite's
review and analysis of the opportunity. Without limiting the above, Marketer
shall provide Mesquite the form of the Bilateral Contract to be entered into for
the sale of the Power in accordance with such opportunity. Marketer shall
provide such information and details regarding the Long-Term Bilateral Contract
opportunity to Mesquite, to the extent possible, at least ten (10) days prior to
the anticipated date of execution of the associated Bilateral Contract. If
Mesquite approves the opportunity and the execution of the Bilateral Contract,
then Marketer shall use all commercially reasonable efforts to enter into the
Bilateral Contract substantially in the form of the Bilateral Contract submitted
to Mesquite for its approval. If Mesquite does not approve the Long-Term
Bilateral Contract opportunity or does not provide a response in sufficient time
to permit the execution of the associated Bilateral Contract or Marketer is
unable to enter into such Bilateral Contract


                                      - 2 -

<PAGE>

following receipt of Mesquite's approval, then the sale of Power subject to such
opportunity shall be made pursuant to the terms set forth in Section 2.2.

                  (b) Short-Term Bilateral Contracts - With regard to any
proposed Bilateral Contract with a term of less than three months ("Short-Term
Bilateral Contract"), Marketer shall use all commercially reasonable efforts to
enter into a Bilateral Contract without the need to obtain the approval of
Mesquite.

                  (c) Terms and Conditions of Bilateral Contracts - If Marketer
is able to enter into either a Long-Term Bilateral Contract or a Short-Term
Bilateral Contract, then the following terms and conditions shall apply to such
sales of Power pursuant to this Section 2.3:

                           (i) Power Revenues - Each month Marketer shall pay
Mesquite Power Revenues equal to (A) until and including December 31, 2003, the

months of October through May, as applicable, and (B) beginning January 1, 2004,
all revenues from the sale of Power resold by Marketer pursuant to Bilateral
Contracts or PJM Contracts equal to the amounts paid to Marketer pursuant to
such Bilateral Contracts or PJM Contracts. Marketer may also provide Bilateral
Contracts from the next day or forward markets to maximize trading margins.
Notwithstanding the foregoing, all profits and losses from such transactions
shall be taken into account in the computation of Power Revenues and Power
Costs.

                           (ii) Power Costs - Each month Mesquite shall pay
Marketer Power Costs equal to (A) all amounts paid by Marketer to Company under
the Camden Transaction Confirmation (exclusive of amounts paid by Marketer in
respect of "Energy Price" as set forth in the Camden Transaction Confirmation),
(B) all other costs paid by Marketer to purchasers of Power under the applicable
Bilateral Contracts or PJM Contracts or for the transmission of Power to the
applicable delivery point under such Bilateral Contracts or PJM Contracts and
(C) taxes or other charges paid by Marketer arising from the sale of Power.

                           (iii) Indemnification - Marketer shall indemnify and
hold Mesquite harmless for any costs, expenses, claims or liabilities incurred
by Mesquite arising from or associated with the resale of Power pursuant to the
Long-Term Bilateral Contracts and the Short-Term Bilateral Contracts as a result
of Marketer's failure to perform in accordance with such contracts, except to
the extent that Marketer's failure to perform in accordance with such contracts
was the result of Company's failure to perform in accordance with the Camden
Transaction Confirmation.

         2.4 Alternative Structures - In addition to the sales made in
accordance with Sections 2.2 and 2.3 above, Marketer shall use all commercially
reasonable efforts to identify other opportunities to maximize the net revenues
for

Power. Without limiting the above, Marketer shall review and analyze the
following other opportunities:

or in part to the market prices for the purchase of natural gas supplies for the
Facility;

                  (b) the sale of Power pursuant to the terms of power pools
other than PJM; and

                  (c) the use of financial derivatives to mitigate price
volatility.

Marketer shall submit such other opportunities to Mesquite for its review and
approval, which shall include Marketer's proposal regarding the terms and
conditions that are applicable to such transactions, including, without
limitation, any proposed sharing of the risks and benefits of such transactions.

         2.5 Taxes - Mesquite shall reimburse Marketer for any taxes, fees or

governmental or regulatory body on the Power sold by Marketer under this
Agreement. The Parties shall cooperate to obtain and to provide any available
certificates of exemption or other evidence of exemption from taxes that might
otherwise apply.

associated with providing the marketing services under this Agreement (including
the ability of the staff assigned to administering this Agreement to also
provide similar services to sales of Power under other power marketing
arrangements with Affiliates of Mesquite) and (b) the risks that Marketer
assumes in purchasing the Power and other services under this Agreement. If the

terminate this Agreement at the beginning of the fourth Annual Period upon

Marketer shall render to Mesquite a statement setting forth a calculation of
Power Revenues and Power Costs for the preceding month and the amounts owed to
or by Marketer pursuant to Section 6.2 of this Agreement with respect to the
preceding month. Within five (5) days following receipt of such statement,
Mesquite shall provide Marketer any objections thereto.

         6.2 Payments - If Power Revenues for a month exceed Power Costs for a

an amount equal to such excess. The Payment Due Date for such payments is the
fifth (5th) business day after receipt of the invoice. If payment is not made by
the Payment Due Date, interest shall be due on the unpaid balance from the
Payment Due Date until the date paid. Interest shall accrue on each calendar day
at the Interest Rate. Notwithstanding the above, if Marketer is not paid for the
resale of the Power sold pursuant to Section 2.2 within thirty (30) days after

amounts owed under this Agreement.

promptly paid (but in any event, within thirty (30) days of the resolution of
the dispute) after such determination with interest calculated at the Interest
Rate from the Payment Due Date to the date the payment is made. Acceptance of a
partial payment shall not be deemed (i) a release or (ii) waiver of Mesquite's
rights under Section 6.4.

         6.4 Audit - Each Party or any third-party representative of a Party
may, at its sole expense and during normal working hours, 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 the provisions of this
Agreement. No adjustments shall be made after the lapse of one (1) year from the
rendition of such statement, charge or computation. This Section 6.4 will
survive any termination of this Agreement for a period of one (1) year from the
date of such termination for the purpose of such statement and payment
adjustments. Payment together with interest at the Interest Rate shall be made
to correct any inaccuracy within thirty (30) days after discovery.

thereof to the other Party as soon as practicable after the occurrence of the
Force Majeure. Such notice may be given orally or in writing, but, if given
orally, it shall be promptly confirmed in writing, giving reasonably full
particulars. Such inability shall be promptly corrected to the extent it may be
corrected through the exercise of reasonable diligence by the Party claiming
inability by reason of Force Majeure.

         7.2 Liability During Force Majeure - Neither Party shall be liable to
the other for any losses or damages, regardless of the nature thereof and
however occurring, whether such losses or damages be direct or indirect,
immediate or remote, by reason of, caused by, arising out of or in any way
attributable to suspension of the performance of any obligation of either Party
to the extent that such suspension occurs because a Party is rendered unable,
wholly or in part, by Force Majeure to perform its obligations.

herein shall mean, cover and include acts of God, epidemics, landslides,

evacuation of facilities and restrict service under this Agreement), restraints
of any court or governmental or regulatory authorities, acts of civil disorder,
acts of industrial disorder which are part of a national or regional strike or
labor dispute, accidents to any transmission facilities, freezing of facilities
or other equipment, necessities for making repairs or alterations to machinery
or equipment, the failure of any governmental authority to grant or renew
authorizations to permit Marketer to resell Power under this Agreement, or any
cause, whether of the kind enumerated in this Agreement or otherwise, that in
the event of each of the above described events or circumstances (a) restricts
or prevents performance under this Agreement, (b) is not reasonably within the
control of the party claiming suspension and (c) by the exercise of due
diligence, such party is unable to prevent or overcome; provided, however, the
settlement of any labor dispute shall be within the sole discretion of the Party
to this Agreement involved in such labor dispute, and the above requirement that
an inability shall be corrected with reasonable diligence shall not apply to
labor disputes.

         7.4 Termination - If a Force Majeure event continues for a period of
ninety (90) consecutive days, then the Parties will discuss the anticipated
length of the Force Majeure event and steps, if any, that are being taken to
resolve the Force Majeure event. If, despite these efforts, the Parties are
unable to resolve the Force


                                      - 7 -

Majeure event, then the Party which did not claim such Force Majeure may at any
time thereafter terminate this Agreement upon thirty (30) days' prior written
notice provided to the other Party to the extent the Force Majeure event has not
been corrected prior to the expiration of such notice period; provided that
Marketer will not terminate this Agreement pursuant to this Section 7.4 so long
as Marketer is being paid the Power Marketing Fee pursuant to Section 3.1
hereof.

                                  ARTICLE VIII
                                   ARBITRATION

         8.1 Submission of Dispute for Arbitration - Any controversy pertaining
to matters expressly made subject to arbitration under this Agreement shall be
determined in accordance with the rules of the American Arbitration Association
by a board of arbitration, consisting of three (3) members, upon notice of
submission given by either Party, which notice shall also name one (1)
arbitrator. The Party receiving such notice, shall, by notice to the other Party
within ten (10) days thereafter, name the second arbitrator, or failing to do
so, the Party giving notice of submission shall name the second arbitrator. The

the support of a majority of the arbitrators. If the board of arbitration is
unable to reach such decision, new arbitrators will be named and shall act
hereunder, at the request of either Party, in a like manner as if none had been
previously named. After the presentation of evidence has been concluded, each
Party shall submit to the arbitrators a final offer of its proposed resolution
of the dispute. The arbitrators shall approve the final offer of one Party,
without modification and reject that of the other. In considering the evidence
and deciding which final offer to approve, the arbitrators shall be bound by the
criteria described in the applicable section of this Agreement.

rendered in writing and supported by written reasons. The decision of the
arbitrators shall be final and binding upon the Parties and will be complied
with by the Parties. The decision of the arbitrators shall be kept confidential
in accordance

with Section 11.1 of this Agreement. Each Party shall bear the expenses of its
chosen arbitrator, and the expenses of the third arbitrator shall be borne
equally by the Parties. Each Party shall bear the compensation and expenses of
its legal counsel, witnesses and employees.

                                     DEFAULT

         9.1 Default Remedies - If an Event of Default shall occur, then the
non-defaulting Party may (a) except to the extent such remedy is limited in this

Agreement in accordance with this Section 9.1 or (c) in the case of Marketer's
failure (i) to pay in accordance with Section 9.2(a) and (ii) to provide
reasonable assurances that it will be able to make payments under this Agreement
for future periods, Mesquite may terminate this Agreement upon thirty (30) days'

the non-defaulting Party shall provide the defaulting Party written notice of
the Event of Default.

         9.2 Events of Default - An "Event of Default" shall mean:

                  (a) Failure to Pay - The failure of either Party to make
payments in full and when due pursuant to this Agreement, which failure is not
cured within twenty (20) days after written notice of such default by the
non-defaulting Party to the defaulting Party;

                  (b) Failure to Perform - Except with respect to the payment of
amounts owed under this Agreement which is governed by Section 9.2(a), the
failure of either Party to perform any of its material obligations under this
Agreement and such failure is not cured within forty-five (45) days after
written notice thereof by the non-defaulting Party provided to the defaulting
Party specifying the failure; provided that if the nature of the failure is such
that the Event of Default cannot be cured within such forty-five (45) Day period
and if the defaulting Party has commenced and is diligently pursuing such cure,
such period shall be extended for such further period not to exceed three (3)
months after the notice of the default, as shall be necessary for non-defaulting
Party to cure the failure;

                  (c) Voluntary Bankruptcy - Either Party files for voluntary
bankruptcy or similar proceedings; or

                  (d) Involuntary Bankruptcy - Either Party has filed against it
involuntary bankruptcy or similar proceedings and such proceedings are not
dismissed or stayed within ninety (90) days; provided, however, that the events
described in (c) and (d) of this Section 9.2 of this Agreement shall not
constitute an Event of Default if the debtor in possession, trustee, or other
party exercising

                                      - 9 -

<PAGE>

control over the assets of the party in default affirms this Agreement within a
reasonable period of time and provides evidence reasonably satisfactory to the
non-defaulting Party, of the ability to continue the performance of the
defaulting party's obligations under this Agreement.

                                    ARTICLE X
                                REGULATORY BODIES

         10.1 Laws and Regulations - This Agreement shall be subject to all
valid applicable governmental laws and orders, regulatory authorizations,
directives, rules and regulations of any governmental body or official having
jurisdiction over the Parties, the Power or this Agreement or any provision
thereof or any Transaction under this Agreement; but nothing contained herein
shall be construed as a waiver of any right to question or contest any such law,
order, rule or regulation in any forum having jurisdiction. The rights and
obligations of the Parties associated with the purchase and sale of Power shall
not be effective until all Regulatory Approvals have been obtained; provided,
however, that if Regulatory Approvals are not issued by applicable governmental
authorities by the effective date of any Transaction, either Party may terminate
such Transaction without further obligation or liability to the other Party.

         10.2 Reliance on Law - The Parties are entitled to act in accordance
with a law until such law is amended, reversed or otherwise disposed in a final
nonappealable order.

         10.3 Cooperation - The Parties shall cooperate to ensure compliance
with all governmental regulation, including obtaining and maintaining all
necessary regulatory authorizations or any reasonable exchange or provision of
information needed for filing or reporting requirements. Without limiting the
above, Marketer represents that it has all Regulatory Approvals that are
required on the date of this Agreement to purchase and sell the Power pursuant
to the terms of this Agreement, except to the extent that the failure to have
obtained and maintained such Regulatory Approval could not reasonably be
expected to have a material adverse effect on Marketer or its ability to perform
its obligations under this Agreement. Marketer covenants that it will use all
commercially reasonable efforts to maintain such Regulatory Approvals for the
term of this Agreement and to obtain and maintain any additional Regulatory
Approvals that may be imposed following the date of this Agreement.

         10.4 Changes in Law or Regulation - If any federal or state statute or
regulation or order by a court of law or regulatory authority directly or
indirectly (a) prohibits performance under this Agreement, (b) makes such
performance illegal or impossible or (c) effects a change in a substantive
provision of this Agreement which has a significant material adverse impact upon

         11.11 Severability - Except as otherwise stated herein, any article or
section declared or rendered unlawful by a court of law or regulatory authority
with jurisdiction over the Parties or deemed unlawful because of a statutory
change will not otherwise affect the lawful obligations that arise under this
Agreement.

power and authority to enter into and perform its obligations under this
Agreement and that this Agreement constitutes a legal, valid and binding
