pursuant to this Section 5.2, including the right to contest the rates or
charges for the services provided under this Agreement, from time to time, in

                          FIRM TRANSPORTATION AGREEMENT

         THIS AGREEMENT, made and entered into this 29th day of October, 2001,
by and between Texas Gas Transmission Corporation, a Delaware corporation,
hereinafter referred to as "Texas Gas," and Mississippi Valley Gas Company, a
Mississippi corporation, hereinafter referred to as "Customer,"

                                   WITNESSETH:

         WHEREAS, Customer has natural gas which it desires Texas Gas to move
through its existing facilities; and

         WHEREAS, Texas Gas has the ability in its pipeline system to move
natural gas for the account of Customer; and

         WHEREAS, Customer desires that Texas Gas transport such natural gas for
the account of Customer; and

         WHEREAS, Customer and Texas Gas are of the opinion that the transaction
referred to above falls within the provisions of Section 284.223 of Subpart G of
Part 284 of the Federal Energy Regulatory Commission's (Commission) regulations
and the blanket certificate issued to Texas Gas in Docket No. CP88-686-000, and
can be accomplished without the prior approval of the Commission;

         NOW, THEREFORE, in consideration of the premises and of the mutual
covenants herein contained, the parties hereto covenant and agree as follows:

                                    ARTICLE I

Definitions

1.1      Definition of Terms of the General Terms and Conditions of Texas Gas's
FERC Gas Tariff on file with the Commission is hereby incorporated by reference
and made a part of this Agreement.

                                   ARTICLE II

Transportation Service

2.1      Subject to the terms and provisions of this Agreement, Customer agrees
to deliver or cause to be delivered to Texas Gas, at the Point(s) of Receipt in
Exhibit "A" hereunder, gas for transportation, and Texas Gas agrees to receive,
transport, and redeliver, at the Point(s) of Delivery in Exhibit "B" hereunder,
equivalent quantities of gas to Customer or for the account of Customer, in
accordance with Section 3 of Texas Gas's effective FT Rate Schedule and the
terms and conditions contained herein, up to 20,476 MMBtu per day, which shall
be Customer's Firm Transportation Contract Demand.

2.2      Customer shall reimburse Texas Gas for the quantity of gas required for
fuel, company use, and unaccounted for associated with the transportation
service hereunder in accordance with Section 16 of the General Terms and
Conditions of Texas Gas's FERC Gas Tariff. Texas Gas may adjust the fuel
retention percentage as operating circumstances warrant; however, such change
shall not be retroactive. Texas Gas agrees to give Customer thirty (30) days'
written notice before changing such percentage.

<PAGE>

2.3      Texas Gas, at its sole option, may, if tendered by Customer, transport
daily quantities in excess of the Transportation Contract Demand.

2.4      In order to protect its system, the delivery of gas to its customers
and/or the safety of its operations, Texas Gas shall have the right to vent
excess natural gas delivered to Texas Gas by Customer or Customer's supplier(s)
in that part of its system utilized to transport gas received hereunder. Prior
to venting excess gas, Texas Gas will use its best efforts to contact Customer
or Customer's supplier(s) in an attempt to correct such excess deliveries to
Texas Gas. Texas Gas may vent such excess gas solely within its reasonable
judgment and discretion without liability to Customer, and a pro rata share of
any gas so vented shall be allocated to Customer. Customer's pro rata share
shall be determined by a fraction, the numerator of which shall be the quantity
of gas delivered to Texas Gas at the Point of Receipt by Customer or Customer's
supplier(s) in excess of Customer's confirmed nomination and the denominator of
which shall be the total quantity of gas in excess of total confirmed
nominations flowing in that part of Texas Gas's system utilized to transport
gas, multiplied by the total quantity of gas vented or lost hereunder.

2.5      Any gas imbalance between receipts and deliveries of gas, less fuel and
PVR adjustments, if applicable, shall be cleared each month in accordance with
Section 17 of the General Terms and Conditions in Texas Gas's FERC Gas Tariff.
Any imbalance remaining at the termination of this Agreement shall also be
cashed-out as provided herein.

                                   ARTICLE III

Scheduling

3.1      Customer shall be obligated four (4) working days prior to the end of
each month to furnish Texas Gas with a schedule of the estimated daily
quantity(ies) of gas it desires to be received, transported, and redelivered for
the following month. Such schedules will show the quantity(ies) of gas Texas Gas
will receive from Customer at the Point(s) of Receipt, along with the identity
of the supplier(s) that is delivering or causing to be delivered to Texas Gas
quantities for Customer's account at each Point of Receipt for which a
nomination has been made.

3.2      Customer shall give Texas Gas, after the first of the month, at least
twenty-four (24) hours' notice prior to the commencement of any day in which
Customer desires to change the quantity(ies) of gas it has scheduled to be
delivered to Texas Gas at the Point(s) of Receipt. Texas Gas agrees to waive
this 24-hour prior notice and implement nomination changes requested by Customer
to commence in such lesser time frame subject to Texas Gas's being able to
confirm and verify such nomination change at both Receipt and Delivery Points,
and receive PDAs reflecting this nomination change at both Receipt and Delivery
Points. Texas Gas will use its best efforts to make the nomination change
effective at the time requested by Customer; however, if Texas Gas is unable to
do so, the nomination change will be implemented as soon as confirmation is
received.

                                   ARTICLE IV

Points of Receipt, Delivery, and Supply Lateral Allocation

4.1      Customer shall deliver or cause to be delivered natural gas to Texas
Gas at the Point(s) of Receipt specified in Exhibit "A" attached hereto and
Texas Gas shall redeliver gas to Customer or for the account of Customer at the
Point(s) of Delivery specified in Exhibit "B" attached hereto in accordance with
Sections 7 and 15 of the General Terms and Conditions of Texas Gas's FERC Gas
Tariff.

                                       2

<PAGE>

4.2      Customer's preferential capacity rights on each of Texas Gas's supply
laterals shall be as set forth in Exhibit "C" attached hereto, in accordance
with Section 34 of the General Terms and Conditions of Texas Gas's FERC Gas
Tariff.

                                    ARTICLE V

Term of Agreement

5.1      This Agreement shall become effective November 1, 2001, and remain in
full force and effect for a primary term beginning November 1, 2001, (with the
rates and charges described in Article VIII becoming effective on that date) and
extending for a period of one year(s) from that date, or through October 31,
2002; with extensions of one year at the end of the primary term and each
additional term thereafter unless written notice is given at least three hundred
sixty-five (365) days prior to the end of such term by either party.

                                   ARTICLE VI

Point(s) of Measurement

6.1      The gas shall be delivered by Customer to Texas Gas and redelivered by
Texas Gas to Customer at the Point(s) of Receipt and Delivery hereunder.

6.2      The gas shall be measured or caused to be measured by Customer and/or
Texas Gas at the Point(s) of Measurement which shall be as specified in Exhibits
"A", "A-I", and "B" herein. In the event of a line loss or leak between the
Point of Measurement and the Point of Receipt, the loss shall be determined in
accordance with the methods described in Section 3, "Measuring and Measuring
Equipment," contained in the General Terms and Conditions of Texas Gas's FERC
Gas Tariff.

                                   ARTICLE VII

Facilities

7.1      Texas Gas and Customer agree that any facilities required at the
Point(s) of Receipt, Point(s) of Delivery, and Point(s) of Measurement shall be
installed, owned, and operated as specified in Exhibits "A", "A-I", and "B"
herein. Customer may be required to pay or cause Texas Gas to be paid for the
installed cost of any new facilities required as contained in Sections 1.3, 1.4,
and 1.5 of Texas Gas's FT Rate Schedule and Section 30 of the General Terms and
Conditions. Customer shall only be responsible for the installed cost of any new
facilities described in this Section if agreed to in writing between Texas Gas
and Customer.

                                  ARTICLE VIII

Rates and Charges

8.1      Each month, Customer shall pay Texas Gas for the service hereunder an
amount determined in accordance with Section 5 of Texas Gas's FT Rate Schedule
contained in Texas Gas's FERC Gas Tariff, which Rate Schedule is by reference
made a part of this Agreement. The maximum rates for such service consist of a
monthly reservation charge multiplied by Customer's firm transportation demand
as specified in Section 2.1 herein. The reservation charge shall be billed as of
the effective date of this Agreement. In addition to the monthly reservation
charge, Customer agrees to pay Texas Gas each month the maximum commodity charge
up to Customer's transportation contract demand. For any quantities delivered by
Texas Gas in excess of Customer's transportation contract

                                       3

<PAGE>

demand, Customer agrees to pay the maximum FT overrun commodity charge. In
addition, Customer agrees to pay:

         (a)      Texas Gas's Fuel Retention percentage(s).

         (b)      The currently effective GRI funding unit, if applicable, the
                  currently effective FERC Annual Charge Adjustment unit charge
                  (ACA), the currently effective Take-or-Pay surcharge, or any
                  other then currently effective surcharges, including but not
                  limited to Order 636 Transition Costs.

If Texas Gas declares force majeure which renders it unable to perform service
herein, then Customer shall be relieved of its obligation to pay demand charges
for that part of its FT contract demand affected by such force majeure event
until the force majeure event is remedied.

Unless otherwise agreed to in writing by Texas Gas and Customer, Texas Gas may,
from time to time, and at any time selectively after negotiation, adjust the
rate(s) applicable to any individual Customer; provided, however, that such
adjusted rate(s) shall not exceed the applicable Maximum Rate(s) nor shall they
be less than the Minimum Rate(s) set forth in the currently effective Sheet No.
10 of Texas Gas's FERC Gas Tariff. If Texas Gas so adjusts any rates to any
Customer, Texas Gas shall file with the Commission any and all required reports
respecting such adjusted rate.

8.2      In the event Customer utilizes a Secondary Point(s) of Receipt or
Delivery for transportation service herein, Customer will continue to pay the
monthly reservation charges as described in Section 8.1 above. In addition,
Customer will pay the maximum commodity charge applicable to the zone in which
gas is received and redelivered up to Customer's transportation contract demand
and the maximum overrun commodity charge for any quantities delivered by Texas
Gas in excess of Customer's winter season or summer season transportation
contract demand. Customer also agrees to pay the ACA, Take-or-Pay Surcharge, GRI
charges, fuel retention charge, and any other effective surcharges, if
applicable, as described in Section 8.1 above.

8.3      It is further agreed that Texas Gas may seek authorization from the
Commission and/or other appropriate body for such changes to any rate(s) and
terms set forth herein or in Rate Schedule FT, as may be found necessary to
assure Texas Gas just and reasonable rates. Nothing herein contained shall be
construed to deny Customer any rights it may have under the Natural Gas Act, as
amended, including the right to participate fully in rate proceedings by
intervention or otherwise to contest increased rates in whole or in part.

8.4      Customer agrees to fully reimburse Texas Gas for all filing fees, if
any, associated with the service contemplated herein which Texas Gas is required
to pay to the Commission or any agency having or assuming jurisdiction of the
transactions contemplated herein.

8.5      Customer agrees to execute or cause its supplier or processor to
execute a separate agreement with Texas Gas providing for the transportation of
any liquids and/or liquefiables, and agrees to pay or reimburse Texas Gas, or
cause Texas Gas to be paid or reimbursed, for any applicable rates or charges
associated with the transportation of such liquids and/or liquefiables, as
specified in Section 24 of the General Terms and Conditions of Texas Gas's FERC
Gas Tariff.
