                              CONDITIONS PRECEDENT

approvals by both the Federal Energy Regulatory Commission and Mississippi
Public Service Commission prior to transfer and completion of the Starkville
Lateral in accordance with the terms and conditions of the purchase and sale

Company and the purchase by Shipper of the Starkville Lateral are not received
upon terms satisfactory to both parties by October 31, 2000, or (2) the
Starkville Lateral transaction is not completed within 60 days of the last of

less than sixty (60) days written notice to Company, and such notice must be
given no later than January 31,2001.

                                   ARTICLE VI
                                  REMUNERATION

         6.1      Shipper shall pay Company monthly for the transportation
services rendered hereunder the charges specified in Rate Schedule FT, Rate
Schedule FT-NN, as discounted in accordance with Exhibit E, and on each
effective Addendum, as applicable, including any penalty assessed under the
applicable FT or FT-NN Rate Schedule FT and the General Terms and Conditions.
For new service requested from Company under Rate Schedule FT or FT-NN from and
after the date of this Service Agreement, Company shall notify Shipper as soon
as practicable of the date services will commence hereunder, and if said date is
not the first day of the month, the Reservation Charge for the first month of
service hereunder shall be adjusted to reflect only the actual number of days
during said month that transportation service is available. Company may agree
from time to time to discount the rates charged Shipper for services provided
hereunder in accordance with the provisions of Rate Schedule FT and/or FT-NN, as
applicable. Said discounted charges shall be set forth on Exhibit E hereto.

shall be subject to increase or decrease pursuant to any order issued by the
Commission in any proceeding initiated by Company or applicable to the services
performed hereunder. Shipper agrees that Company shall, without any further
agreement by Shipper, have the right to change from time to time, all or any
part of Rate Schedule FT or FT-NN, as applicable, or the General Terms and
Conditions thereto, including without limitation the right to change the rates
and charges in effect thereunder, pursuant to Section 4(d) of the Natural Gas
Act as may be deemed necessary by Company, in its reasonable judgment, to assure
just and reasonable service and rates under the Natural Gas Act. It is
recognized, however, that once an Addendum has been issued. Company cannot
increase the Reservation Charge to be paid by Shipper under that Addendum.
Nothing contained herein shall prejudice the rights of Shipper to contest at any
time the changes made pursuant to this Section 6.2, from time to time, in any
subsequent rate proceedings by Company under Section 4 of the Natural Gas Act or
to file a compliant under Section 5 of the Natural Gas

                                   ARTICLE VII
                               SPECIAL PROVISIONS

         7.1      If Shipper is a seller of gas under more than one Service

2.2 of the General Terms and Conditions and the terms and conditions of the
Supply Pool Balancing Agreement executed by Shipper and Company pursuant thereto

nomination, provided that the seller (i) has entered into a Supply Pool
Balancing Agreement with Company and (ii) submits a corresponding nomination to
deliver gas to Shipper from its aggregate supply pool.

                                  ARTICLE VIII

the provisions of Rate Schedule FT and/or FT-NN, as applicable, and the General

                                                    Service Agreement No. FSNG46

         8.4      This Agreement shall bind and benefit the successors and
assigns of the respective parties hereto. Subject to the provisions of Section
22 of the General Terms and Conditions applicable hereto, neither party may
assign this Agreement without the prior written consent of the other party,
which consent shall not be unreasonably withheld; provided, however, that either

deed of trust, indenture or similar instrument.

         8.5      Exhibits A, A-l, B, B-l and/or E, if applicable, and any
effective Addendum attached to this Agreement constitute a part of this
Agreement and are incorporated herein.

         8.6      This Agreement is subject to all present and future valid laws
and orders, rules, and regulations of any regulatory body of the federal or
state government having or asserting jurisdiction herein. After the execution of
this Agreement for firm transportation capacity from Company, each party shall
make and diligently prosecute all necessary filings with federal or other
governmental bodies, or both, as may be required for the initiation and
continuation of the transportation service which is the subject of this
Agreement and to construct and operate any facilities necessary therefor. Each
party shall have the right to seek such governmental authorizations as it deems
necessary, including the right to prosecute its requests or applications for
such authorization in the manner it deems appropriate. Upon either party's
request, the other party shall timely provide or cause to be provided to the
requesting party such information and material not within the requesting party's
control and/or possession that may be required for such filings. Each party
shall promptly inform the other party of any changes in the representations made
by such party herein and/or in the information provided pursuant to this
paragraph. Each party shall promptly provide the party with a copy of all
filings, notices, approvals, and authorizations in the course of the prosecution
of its filings. In the event all such necessary regulatory approvals have not
been issued or have not been issued on terms and conditions acceptable to
Company or Shipper within twelve (12) months from the date of the initial
application therefor, then Company or Shipper may terminate this Agreement
without further liability or obligation to the other party by giving written
notice thereof at any time subsequent to the end of such twelve-month period,
but prior to the receipt of all such acceptable approvals. Such notice will be
effective as of the date it is delivered to the U.S. Mail, for delivery by
certified mail, return receipt requested.

         8.7      If Shipper experiences the loss of any load after November 1,
1993, by direct connection of such load to the Company's system, Shipper may
reduce its Transportation Demand under this Service Agreement or any other
Service Agreement for firm transportation service between Shipper and Company by
giving Company 30 days prior written notice of such reduction within six (6)
months of the date Company initiates direct services to the industrial customer;
provided, however, that any such reduction shall be applied first to the
Transportation Demand under the Service Agreement with the shortest remaining
contract term.

In order to qualify for a reducing in its Transportation Demand, Shipper must
certify and provide supporting data that:

                                       6



                                                    Service Agreement No. FSNG46

                  (i)      The load was actually being served by Shipper with
                           gas transported by Company prior to November 1, 1993.

                  (ii)     If the load lost by Shipper was served under a firm
                           contract, the daily contract quantity shall be
                           provided.

                  (iii)    If the load lost by Shipper was served under an
                           interruptible contract, the average daily volumes
                           during the latest twelve months of service shall be
                           provided.

Shipper may reduce its aggregate Transportation Demand under all its Service
Agreements by an amount up to the daily contract quantity in the case of the
loss of a firm customer and/or up to the average daily deliveries during the
latest twelve month period in the case of the loss of an interruptible customer.
Such reduction shall become effective thirty days after the date of Shipper's
notice that it desires to reduce its Transportation Demand.

         8.8      This Agreement supersedes and cancels the following firm
transportation Service Agreements between the parties hereto: FT Service
Agreement #907500 dated March 1, 1995 and FT-NN Service Agreement #907501 dated

         IN WITNESS WHEREOF, this Agreement has been executed by the parties as
of the date first written above by their respective duly authorized officers.
