                     FIRM NO-NOTICE TRANSPORTATION AGREEMENT
                                Rate Schedule NNS


         THIS AGREEMENT, made and entered into this 1st day of November, 1997,
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 was receiving a firm, bundled city gate sales service
from Texas Gas on May 18, 1992, under provisions of a sales service agreement
dated November 1, 1997; and

         WHEREAS, Customer desires to continue receiving the equivalent
transportation service formerly embedded in its bundled sales service, or
portion thereof, as no-notice service; and

         WHEREAS, Texas Gas desires to provide and Customer desires to receive
such no-notice service under its NNS Rate Schedule on the terms and conditions
set forth herein;

         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 The definitions in Section 3 of Rate Schedule NNS, as well as Section 1 of
the General Terms and Conditions of Texas Gas's FERC Gas Tariff, are hereby
incorporated by reference and made a part of this Agreement.

                              ARTICLE II. QUANTITY

2.1 Pursuant to Texas Gas's Rate Schedule NNS and 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 to
Customer at the Point(s) of Delivery in Exhibit "B" hereunder, the daily and
seasonal quantities of gas set forth herein. The parties agree that the
transportation service provided hereunder shall be a firm service provided by
combining pipeline capacity (the "Nominated" portion of the service) and storage
capacity (the "Unnominated" portion of the service) into a single transportation
service.

2.2 The maximum daily quantity of gas which Texas Gas shall be obligated to
transport and redeliver to Customer, and which Customer shall be obligated to
receive, is Customer's applicable Contract Demand expressed on a seasonal basis
as set forth below:

<Table>

<S>                                                   <C>

                        Winter                         50,429
                        Summer                          5,000
</Table>

2.3 The above Contact Demands consist of a Nominated Daily Quantity, for which
Customer is responsible for scheduling the delivery of gas supplies into Texas
Gas's system, and an Unnominated Daily Quantity, which is


                                       2

automatically delivered from storage by Texas Gas to meet Customer's
requirements. Those quantities, expressed on a seasonal basis, are set forth
below:

<Table>
<Caption>
              Nominated Daily Quantity                         MMBtu/D

              Winter                                             5,000
              Summer                                             5,000

<S>                                                            <C>
              Winter                                            45,429
</Table>

2.4 Customer's Excess Unnominated Daily Quantity shall be 5,043 MMBtu per day,
which is ten percent (10%) of its Winter Contract Demand.

2.5 The maximum seasonal quantities of gas which Texas Gas shall be obligated to
transport and deliver to Customer, and which Customer shall be obligated to
receive, are Customer's Seasonal Quantity Entitlements as set forth below:

<Table>
<Caption>
                     Seasonal
                Quantity Entitlement                              MMBtu
                --------------------                            ---------
<S>                                                            <C>
                     Winter                                     1,785,797
                     Summer                                     1,070,000
</Table>

2.6 A portion of Customer's Winter Quantity Entitlement consists of unnominated
quantities of gas delivered by Texas Gas from storage. The maximum net quantity
of gas Texas Gas is obligated to deliver to Customer from storage during any
Winter Season is Customer's Unnominated Seasonal Quantity, which is 1,030,797
MMBtu. In addition to scheduling the receipt of Customer's Summer Quantity
Entitlement, Customer is also responsible for the redelivery each summer of that
portion of Customer's Unnominated Seasonal Quantity actually used the prior
winter, as more fully set forth herein.

2.7 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.

2.8 Texas Gas, at its sole option, may, if tendered by Customer, transport
daily quantities in excess of Customer's Contract Demand.

2.9 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 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
suppliers 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.

                           ARTICLE III. SCHEDULING OF
                       CUSTOMER'S NOMINATED DAILY QUANTITY

3.1 This Article III only applies to the scheduling of the Nominated Daily
Quantity portion of Customer's Contract Demand and not to the Unnominated Daily
Quantity of Unnominated Seasonal Quantity delivered from storage.

3.2 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.

3.3 Customer shall give Texas Gas, after the first of the month, 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. If Customer's nomination change does not require
Texas Gas to interrupt service to another customer, Texas Gas will agree 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 PDA's 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 AND 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.

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, 1997, and shall remain in
full force and effect for a primary term of five (5) years ending October 31,
2002. At the end of such primary term, or any subsequent rollover term, this
Agreement shall automatically be extended for an additional rollover term of
five (5) years, unless Customer terminates this Agreement at the end of such
primary or rollover term by giving Texas Gas at least 365 days advance written
notice prior to the expiration of the primary term or any subsequent rollover
term.

                        ARTICLE VI. POINT OF MEASUREMENT

6.1 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 First Revised Volume No. 1 of
Texas Gas's FERC Gas Tariff.

<PAGE>
                             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. 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 Unless otherwise agreed to in writing by Texas Gas and Customer, Customer
shall pay to Texas Gas each month a Reservation Charge which shall consist of
the applicable Contract Demand as specified in this Agreement multiplied by the
applicable demand rate per MMBtu. The Reservation Charge shall be billed as of
the effective date of this Agreement. Unless otherwise agreed to in writing by
Texas Gas and Customer, Customer shall also pay Texas Gas the Maximum Commodity
Rate per MMBtu of gas delivered by Texas Gas for no-notice transportation
services rendered to Customer up to Customer's applicable Contract Demand. For
all gas quantities delivered in excess of Customer's applicable Contract Demand
on any day, Customer shall pay the NNS Overrun Rate per MMBtu, as described
in the NNS Rate Schedule. In addition, Customer shall pay any and all currently
effective demand or commodity surcharges, including but not limited to, the GRI
Funding Unit, the FERC ACA Unit Charge, Texas Gas's Take-or-Pay surcharge, and
Order 636 Transition Costs surcharge.

         If Texas Gas declares force majeure which renders it unable to perform
service for Customer under this Agreement either in whole or part, then Customer
shall be relieved of its obligation to pay NNS demand charges for that part of
its NNS 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 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
delivered up to Customer's applicable Contract Demand and the maximum overrun
commodity charge for any quantities delivered by Texas Gas in excess of
Customer's Seasonal Quantity Entitlement. 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 Texas Gas's tariff, 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 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.

<PAGE>
                           ARTICLE IX. WINTER SERVICE


9.1 Customer will only be required to nominate into Texas Gas's system a
quantity of gas up to the Nominated Daily Quantity.

9.2 In addition to the Nominated Daily Quantity actually scheduled by Customer,
Texas Gas will adjust deliveries from storage up to Customer's Unnominated Daily
Quantity to meet Customer's city gate requirements up to Customer's Winter
Contract Demand.

9.3 In addition, Customer may exceed its Unnominated Daily Quantity by a
quantity equal to its Excess Unnominated Daily Quantity (i.e. 10% of its Winter
Contract Demand) for up to two consecutive gas days without a penalty; however,
total deliveries to the Customer may not exceed the Customer's Winter Contract
Demand. Texas Gas will notify the Customer within four (4) hours of the end of
the gas day in which Customer has exceeded its Unnominated Daily Quantity. If
the Customer does not cease taking such Excess Unnominated Daily Quantity from
Texas Gas's storage after two consecutive gas days, then pipeline may assess a
penalty of $15 per MMBtu of such excess gas taken and may issue an operational
flow order requiring Customer to immediately inject additional gas supply and/or
reduce city gate deliveries so that the customer is no longer exceeding his
Unnominated Daily Quantity.

9.4 Monthly Maximum Withdrawal: No more than 50% of Customer's Unnominated
Seasonal Quantity shall be withdrawn in any consecutive thirty (30) day period.

9.5 Seasonal Minimum and Maximum Withdrawal: No more than 105% of Customer's
Unnominated Seasonal Quantity shall be withdrawn by March 1; provided further,
that no less than 68% and no more than 100% of Customer's Unnominated Seasonal
Quantity shall be withdrawn by April 1 (the end of the Winter Season).

9.6 Adjusted Unnominated Daily Quantity: As Customer's Unnominated Seasonal
Quantity (USQ) is withdrawn, that portion of Customer's Unnominated Daily
Quantity (UDQ) available to Customer shall be adjusted. Customer's Adjusted
Unnominated Daily Quantity (UDQ) shall be equal to the greater of its average
winter daily unnominated quantity (i.e., Customer's USQ divided by the total
number of Winter days the UDQ is available) or the applicable percentage of its
Unnominated Daily Quantity (UDQ) as set forth in the following table:

<Table>
<Caption>
                      % USQ Withdrawn          % UDQ Available
                      ---------------          ---------------
<S>                                            <C>

                            75%                       90%
                            80%                       85%
                            85%                       80%
                            90%                       75%
</Table>

9.7 During the Winter Season, Texas Gas will also inject gas into storage on a
best efforts basis as part of NNS service. Although such injections will be
done on a best efforts basis, Texas Gas will be presumed, unless it gives notice
to the contrary, to be able to inject into storage such quantities of gas as to
take into account routine variations in no-notice deliveries. If Texas Gas is
unable to make such best efforts injections, it will advise Customer by posting
on its electronic bulletin board. However, no presumption will exist for
nonroutine situations (e.g. injections in excess of 15% of Customer's Winter
Contract Demand or sustained injections of more than five days) and Customer
must give 24 hours advance written notice to Texas Gas of quantities it desires
to inject into storage, so that Texas Gas can determine the extent to which it
can make such injections and adjust its operations accordingly.

                           ARTICLE X. SUMMER SERVICE

10.1 Texas Gas shall deliver to Customer at the city gate during each Summer
Season up to the Customer's Summer Contract Demand and Summer Quantity
Entitlement as nominated by Customer.




                                       6
<PAGE>
10.2 Pursuant to the provisions set forth below, Customer shall deliver in kind
to Texas Gas during each Summer Season a quantity of gas equal to that portion
of Customer's Unnominated Seasonal Quantity actually utilized by Customer
(including any infield transfers pursuant to Section 25.8(c) of the General
Terms and Conditions of this tariff) during the prior Winter Season. Customer
shall reserve and utilize such portion of its Summer Contract Demand as
necessary to redeliver such volumes into storage.

10.3 Maximum Daily Injection Quantity: To protect the storage formations and
allow uniform filling of the storage reservoirs, Customer will be required to
adhere to certain injection limits (calculated as a percentage of the
Unnominated Seasonal Quantity), throughout the summer injection period. During
the Summer Season Customer may, on a daily basis, inject according to the
following table:

<Table>
<Caption>
                   % of Unnominated            Maximum Available
                   Seasonal Quantity             Injection Rate
                        Injected                  (% of USQ)
                   ----------------            -----------------
<S>                                            <C>

                        0%- 65%                         1.3%
                        65%-90%                         1.1%
                         >90%                           0.6%
</Table>

10.4 Inventory verification tests will be conducted on a semiannual basis. These
tests require the temporary suspension of individual storage field activities
(injections and withdrawals) for a period of approximately two weeks. If
conditions will not permit the full maximum daily injection or withdrawal
quantity, Texas Gas may temporarily adjust the limit and allow makeup quantities
on succeeding days. Texas Gas will provide at least 45 days prior notice in
regard to the scheduling of these shut-in periods.

10.5 During the Summer Season, Texas Gas will also withdraw gas from storage on
a best efforts basis as part of the NNS service. Although such withdrawals will
be done on a best efforts basis, Texas Gas will be presumed, unless it gives
notice to the contrary, to be able to withdraw from storage such quantities of
gas as to take into account routine variations in no-notice services. If Texas
Gas is unable to make such best efforts withdrawals, it will advise Customer by
posting on its electronic bulletin board. However, no presumption will exist for
nonroutine situations (e.g. withdrawals in excess of 10% of Customer's Winter
Contact Demand or sustained withdrawals of more than five days) and Customer
must give 24 hours advance written notice to Texas Gas of quantities it desires
to withdraw from storage, so that Texas Gas can determine the extent to which it
can make such withdrawals and adjust its operations accordingly.

10.6 To assist Texas Gas's operational and maintenance scheduling through the
Summer Season, Customer will notify Texas Gas by March 15 of each year, with
updates monthly, of the quantities it intends to inject monthly during the
immediately upcoming Summer Season; such injection schedule provided by Customer
is a best efforts estimate and may be revised as necessary. Texas Gas will use
its reasonable efforts to coordinate its test, maintenance, alteration and
repair activities during such Summer Season to accommodate Customer's request.

                            ARTICLE XI. MISCELLANEOUS
