                           APPENDIX B 
                       TERMS & CONDITIONS 
                           WARRANTY LETTER AGREEMENT
1.  DEFINITIONS: 

a.  MMBtu: The unit of measurement shall be one million British Thermal Units 
(MMBtu),  determined on the basis of gross heating value (determined at
60degreesF when saturated with water vapor at an absolute pressure of 14.73
psia, adjusted for water content as delivered). 

b.  Day: A period from 7:00 A.M. at the Sales Points until 7:00 A.M. on the
following day.

c.  Month: A period from 7:00 A.M. on the first Day of the calendar month and
ending at 7:00 A.M. on the first Day of the following month.

2.  DECONTROL: Buyer and Seller agree, to the extent they are legally
empowered to do so, that gas sold under this Agreement shall not be subject to
control by any governmental agency. Instead, the parties intend to have their
negotiated price govern. 

3.  BUYER'S OBLIGATIONS: Buyer will notify Mobil, in writing, on or before the
20th Day of each Month, of the quantity of gas Buyer willt purchase each Day
during the next Month (Purchase Quantity).  Buyer may request any quantity,
including zero, up to the MCQ.  Except to the extent prevented by Force
Majeure, it is Buyer's intention to take each day at least 80% of all gas
nominated at the Sales Point(s).  As to any  failure to take at least 80% of
the monthly nominated quantity at the delivery point, or take during any month
at least 80% of the nominated quantity at the delivery point,  Buyer shall pay
Seller, in addition to the commodity price set forth on Appendix A, the
difference between 80% of the nominated quantity and the quantities actually
delivered multiplied by 20% of the commodity price. 

4.  SELLER'S OBLIGATIONS: Mobil agrees to deliver each Day at the Sales 
Point(s) a quantity of gas within +-10% of the Purchase Quantity (Daily
Operating Tolerance), up to the MCQ.  Mobil's obligation to deliver gas during
any Month shall be met by deliveries within +-5% (Monthly Operating Tolerance)
of the Monthly Purchase Quantity (the sum of the Purchase Quantities in effect
each Day during such Month). 

5.  DAMAGES: If Mobil tenders a quantity of gas which is less than the
Purchase  Quantity and outside the Daily Operating Tolerance and is not
excused by Mobil's force  majeure or an act or omission of Buyer or Buyer's
transporter, Mobil shall pay damages for such failure in an amount equal to
the increased costs which Buyer demonstrates it paid for replacement Gas. 
Such increased costs, if any, shall be measured by comparing:(i) the total
costs paid by Buyer for the replacement gas and  Buyer's costs  to have such
gas delivered to the Sales Point(s) to (ii) the total costs which  would 
otherwise have been paid by Buyer to purchase gas hereunder and have such gas 
delivered  to its facilities, provided that it is understood that Buyer will
purchase the least expensive replacement gas consistent with consideration of
reliability of supply. If, however, any such shortfall does not result in
Buyer receiving less gas at its facilities than required, but rather
results in an imbalance under Buyer's transportation agreement(s), Mobil shall
have no obligation to pay damages for such shortfall; provided that Mobil,
upon written demand and after having failed to make-up such imbalance within
the maximum period prescribed in Buyer's transportation  agreement(s), shall
reimburse Buyer for any imbalance penalties caused by Mobil's shortfall and
paid by Buyer under its transportation agreement(s).  Buyer's written demand
for damages or reimbursement for imbalance penalties must be received within 
sixty (60) Days after the end of the Month for which damages or imbalance 
penalties are claimed or Buyer shalt be deemed to have waived any right to
seek damages or reimbursement for imbalance penalties for such Month. 

6.  BILLING & PAYMENT: Mobil will provide Buyer an invoice by the 10th Day of 
each Month showing the quantity of gas tendered at the Sales Points during the 
preceding Month and the amount due therefor.  If actual measurement data is
not  available, Mobil will estimate the volume delivered using the best
information available.  Payment shall be made by electronic transmission of
funds, or other means agreeable to the parties, within ten (10) Days of the
date of the date of Mobil's posting its invoice in  the U.S. mails or other
delivery mechanism or service.  A revised invoice will be prepared as soon as
actual data is available, and any additional payment, or refund, will  be made 
within 10 days after the posting of Mobil's invoice in the U.S.  mails or 
other delivery mechanism or service.  Buyer's obligation to pay for gas
received  will not be  excused for force majeure, and will survive the
termination hereof.  If Buyer fails to pay any amount when due,
interest thereon shat I accrue at the lesser of the average prime commercial
rate being charged during the period of delinquency by Citibank, N.A., New
York, N.Y. or the effective maximum legal rate. Each party has the right, at
its  expense and during business hours, to examine the pertinent records and
books of the other to verify the accuracy of any invoice, charge, or
computation. 

7.  MEASUREMENT, QUALITY & PRESSURE: The parties will agree which, as between 
them, is  responsible for measurement.  Measurement requirements will be those
in effect on the pipeline system through which gas is transported to the Sales
Point(s).  Gas tendered by Mobil will meet the quality and pressure
specifications of the pipeline and/or facilities at the Sales Point(s) into
which gas is delivered. 

8.  WARRANTY OF TITLE: Mobil warrants, at the time of delivery, Mobil's title 
to all gas delivered, and that such gas will be free from liens, claims or 
encumbrances.  Mobil indemnifies Buyer against any direct loss, damage or
expense Buyer may sustain from a claim involving gas hereunder prior to
delivery at the Sales Point(s).   Buyer agrees to indemnify Mobil against any
direct loss, damage, or expense Mobil may sustain from a claim involving gas
hereunder at or after delivery at the Sales Point(s).  Neither party shall be
liable to the other for indirect, consequential, or special damages.

9.  FORCE MAJEURE: Non-performance of any obligation hereunder, other than the 
obligation to pay for gas taken, shall be excused if prevented by an 
occurrence of force maieure, but only for so long as performance is prevented
by such force majeure.  The party claiming excuse shall promptly advise the
other party of such force majeure event and shall, with reasonable efforts,
seek to remedy the occurrence.  Force majeure as used herein shall mean any
event beyond the reasonable control of the party  in  question which prevents,
in whole or part, that party's performance of obligations hereunder, and shall
include, without limitation: floods, hurricanes, breakage or accident to
machinery, plants or pipelines, failure or inability of Mobil's or Buyer's 
transporter(s) to transport gas made available hereunder, and the operation of 
governmental authority (except at the request of the party claiming force 
majeure), but shall not include Buyer's loss of markets or Mobil's inability
to secure gas at prices satisfactory to Mobil. 

10.  PROCESSING: Mobil reserves the right to process gas after delivery at the 
Sales Point(s), and agrees to indemnify Buyer for any Btu losses and
transportation charges incurred by Buyer as a result of Mobil's processing. 

11.  NOTICE: All notices will be in writing and will be deemed delivered when 
mailed by U.S. Mail to the address of the other party. Notice by telecopier
shall be effective when received provided a copy is mailed by the U.S. Mail
within two (2) working days. 

12.  MISCELLANEOUS: This Agreement may not be assigned, except to an affiliate 
of the assigning party, without the prior written consent of the other party,
and shall be governed by the laws of the State of Texas without recourse to
the rules for conflicts of Laws. 

13.  ALABAMA PUBLIC COMMISSION APPROVAL: It is understood that Buyer will seek 
approval  of the Alabama Public Commission of this contract. If the Alabama
Public Commission  issues an order disapproving this contract, or otherwise
indicates its disapproval, then Buyer may terminate this contract by giving 30
days prior written notice.   Should Buyer not so terminate the contract, the
terms and provisions of this contract shall remain in full force and effect
for the remaining term. In the event of any such termination, Mobil shall not
be obligated to refund any amounts received by Mobil for gas delivered under
this contract prior to termination. 


                           APPENDIX C 

During a month, Buyer may request on 24 hours notice a change in the Purchase 
Quantity  for the portion of such Month remaining after the date of such a
request, upward by ***  percent ( *** %) of the MCQ not to exceed the MCQ, or
downward by *** percent(  ***%) of  the MCQ, not less than zero, by notifying
Seller verbally (followed by written  confirmation within 24 hours) of its
desire for such a change.  This swing  option is  available on a *** month
basis ( *** ).  If the swing option is not utilized  in any  given month, that
option becomes null and void and is not available to be  carried  forward for
use in future months (i.e., there is no accumulation of unused  monthly  swing
options).
