                                   ARTICLE III.

3.01  Subject  to the  other  terms and  provisions  of this  agreement,  Seller
expressly  reserves  unto  itself the right,  at its sole cost and  expense,  to
separate and extract liquid and  liquefiable  hydrocarbons,  other than methane,
from the gas upstream of the Pricing Point, together with such methane as cannot
be  separated  from the ethane and heavier  hydrocarbons  separated or extracted
from the gas,  provided  that such  extraction  (i) shall not  reduce  the total
heating value per cubic foot below a level acceptable to Transporter; (ii) shall
not render the gas incapable of meeting the quality specifications  described in
Article IX; and (iii) shall not cause the total number of dekatherms received by
Buyer at the Pricing Point to be less than the number of dekatherms scheduled by
Buyer in accordance with Article IV. All liquid and liquefiable  hydrocarbons so
recovered  shall belong to Seller.  Article XVI hereof  notwithstanding,  Seller
agrees to indemnify and hold Buyer harmless from all claims, liability, damages,
and expenses which may occur or be asserted by reason of Seller's  processing of
gas hereunder.
                                    ARTICLE IV.
                                 QUANTITY OF GAS
4.01  Subject to the other terms and  provisions  of this  agreement,  beginning
November 1, 1990 and daily thereafter  during each Contract Year,  Seller agrees
to make  available  to Buyer at the Pricing  Point(s) a maximum  quantity of gas
equal to the Daily Contract Maximum ("DCM") or such lesser quantity as Buyer may
schedule  from time to time  hereunder.  
4.02  Buyer shall have no  obligation to purchase any minimum quantity of gas
hereunder.
4.03  Buyer shall timely provide to Seller all nomination and scheduling
information required by Transporter in connection with the quantities of gas
Buyer desires to purchase hereunder. Buyer shall notify  Seller  by  telephone
of all changes in its daily scheduled quantities sufficiently in advance so
that Seller may comply with Transporter's advance notice requirements.  Buyer
shall take gas as nearly as practicable at uniform hourly rates of flow, at
uniform daily deliveries and in  conformance with any requirements of
Transporter, subject to Article XII.






4.04 (a) If on any day  during a  Contract  Year  Seller  fails to  deliver  any
portion of the gas  scheduled  by Buyer for  delivery on such day in  accordance
with this Article IV, Buyer shall use reasonable  efforts to replace such gas at
the lowest cost reasonably  available to Buyer. If Buyer is able to replace such
gas from other  sources,  then Seller  shall pay to Buyer,  as Buyer's  sole and
exclusive  remedy for such  failure to deliver (in  addition to the  adjustments
specified in Section 8.03), liquidated damages in an amount equal to:
         (i)  the excess of
              (a)  the price  per  dekatherm  reasonably  paid by Buyer for such
                   replacement  gas,  such price to be adjusted if necessary for
                   pricing point comparability,
over     (b)  the effective price per Dekatherm (including demand and commodity
              charges) that would have been applicable to such gas hereunder,
multiplied by
         (ii) the difference between
         (a)  the quantity of gas so scheduled by Buyer hereunder and
         (b)  the quantity of gas actually delivered hereunder.
If the price paid by Buyer for such  replacement  gas (as  described  in Section
4.04(a)(i)(a))  does not exceed the  effective  contract  price (as described in
Section  4.04(a)(i)(b)),  Buyer shall not receive any  damages.  If Buyer in its
reasonable  discretion,  replaces  such  gas  from  its own  supplies  of gas in
underground storage,  Buyer shall so advise Seller and Seller may elect, in lieu
of paying the liquidated  damages  specified in this paragraph,  to replace such
gas within Buyer's  storage  rights at a time  specified by Buyer.  At such time
Seller shall also reimburse Buyer for any injection and withdrawal  charges paid
or  incurred  by Buyer in  connection  with the  withdrawal  and use of  Buyer's
storage gas and the injection of replacement  quantities  supplied by Seller. In
such case, Seller's  replacement of such gas and reimbursement of such injection
and  withdrawal  charges (in  addition to the  adjustments  specified in Section
8.03) shall constitute Buyer's sole and exclusive remedy for Seller's failure to
deliver gas hereunder.  (b) If on any day during a Contract Year Seller fails to
deliver any portion of the gas  nominated and scheduled by Buyer for delivery on
such day in  accordance  with this Article IV, and if Buyer is unable to replace
such gas from other sources, or if Seller fails to redeliver such gas to storage
as requested by Buyer pursuant to Section 4.04(a), Seller shall pay to Buyer, as
Buyer's  sole and  exclusive  remedy for such failure to deliver (in addition to
the adjustments specified in Section 8.03),






liquidated  damages in an amount  equal to the  applicable  Commodity  Price (as
defined in Section 8.04)  multiplied by the  difference  between the quantity of
gas so  nominated  and  scheduled  by Buyer  hereunder  and the  quantity of gas
actually delivered.
         (c) If Seller fails to deliver the  quantity of gas  scheduled by Buyer
hereunder for sixty (60) consecutive days, (i) Seller (a) may, by giving written
notice to Buyer,  reduce the DCM to the average daily  quantity which Seller was
able to deliver  during such sixty (60) day period;  and (b) may terminate  this
agreement  by giving  written  notice to Buyer prior to the end of the  Contract
Year in which the DCM was so reduced,  provided that such  termination by Seller
shall be effective upon the expiration of the following  Contract Year; and (ii)
Buyer may terminate  this  agreement by giving  written  notice to Seller within
sixty (60) days of the expiration of such sixty 60 day failure period,  and such
termination by Buyer shall be effective upon Seller's receipt of Buyer's notice.
Upon  termination of this agreement by either party pursuant to this  paragraph,
neither party shall incur any further liability hereunder.
         (d)  Anything  to  the  contrary  notwithstanding,  the  provisions  of
Sections  4.04(a),  (b) and (c) and  Section  8.03  shall not apply if  Seller's
failure  to  deliver  is  due  to  a  force  majeure  condition  or  an  adverse
governmental,  action,  as such terms are defined below, or the failure of Buyer
to provide sufficient transportation capacity pursuant to Section 12.02.
                                  
                                  ARTICLE V.
                              DELIVERY PRESSURE
5.01 Seller shall deliver natural gas to Buyer at Transporter's line pressure at
the point(s) of delivery designated in Article VI hereof.
                                  
                                  ARTICLE VI.
                       POINTS OF DELIVERY AND OWNERSHIP
6.01 The point(s) of delivery for gas purchased and sold hereunder shall be
at the interconnection of the facilities of Transporter with the facilities of
third party sellers at Seller's sources of gas. Title shall pass to Buyer at
such point(s) of delivery.

                                  ARTICLE VII.
                               TERM OF AGREEMENT
7.01 Subject to the other provisions  hereof,  this agreement shall be effective
on the date first above  written and shall remain in full force and effect for a
primary term ending  March 31, 2006.  Beyond the primary  term,  this  agreement
shall extend on a year to year basis, unless terminated upon six (6)






months prior written notice by either party.
                               
                                  ARTICLE VIII.
                                     PRICE
8.01  (a)  Subject  to the  other  provisions  of  this  agreement,  for all gas
purchased  hereunder in a month, the Base Contract Price at the Pricing Point(s)
shall be equal to the sum of:
              (i)  one hundred and twenty-one percent (121%) of the arithmetic
                   average of the following:
                   (A)   the arithmetic average of the spot prices for gas
                         delivered to pipelines in the Louisiana Gulf Coast,
                         Onshore and Offshore, published in Natural Gas Week's
                         "Gas Price Report" in the first issue of such month;
                   (B)   the  arithmetic  average of the midpoints of the ranges
                         of  prices  of spot  gas  delivered  to  Tennessee  Gas
                         Pipeline Company in Louisiana and Offshore  (mainline),
                         published in Inside F.E.R.C.'s Gas Market Report in the
                         first issue of such month; and
                   (C)   the regional  average  spot price for gas  delivered to
                         Tennessee  Gas  Pipeline  Company  in South  Louisiana,
                         mainline  in  such  month   published  in  Natural  Gas
                         Intelligence Gas Price Index in the first issue of such
                         month;
         plus        (ii) the actual cost of  transportation  incurred by Seller
                     upstream  of the  Pricing  Point  including  fuel  and  all
                     applicable   surcharges  but  excluding  backhaul  fees  on
                     Transco, not to exceed thirty cents (30) per dekatherm.
         (b) Notwithstanding  Section 8.01(a),  if the  interconnection  between
United Gas Pipeline Company and TGPL at Holmesville,  Mississippi is used as the
Pricing Point for a month, the Base Contract Price shall be equal to one hundred
and twenty-one percent (121%) of the arithmetic average of the following:
                (i)  the average spot price for the week of publication  for gas
                     delivered  to TGPL in  Holmesville,  Mississippi  (Zone 4),
                     published  in Natural  Gas Week in the first  issue of such
                     month in the table  reporting  spot prices of gas delivered
                     to interstate pipelines; and
                (ii) the  midpoint of the range of prices of spot gas  delivered
                     to TGPL in  Mississippi  and  Alabama,  published in Inside
                     F.E.R.C.'s  Gas  Market  Report in the first  issue of such
                     month.






         (c) If any of the indices  described  in Section  8.01(a) or (b) or any
replacement  index  selected by the parties  ceases to be  published,  Buyer and
Seller shall immediately  negotiate a similar,  mutually acceptable  replacement
index or indices.  Until such  replacement  index or indices are  selected,  the
average  determined in accordance with paragraph  8.01(a)(i) or 8.01(b) shall be
based upon the  subparagraphs  of paragraph  8.01(a)(i) or 8.01(b) for which the
necessary indices remain  available.  In the event that none of the average spot
prices described in subparagraphs 8.01(a)(i)(A), (B) and (C) or in subparagraphs
8.01(b)(i) or (ii) can be determined  for a month because the necessary  indices
have  ceased  to be  published  and  the  parties  have  failed  to  agree  upon
replacement  indices,  then either party may refer the matter to the  respective
chief executive  officers of Buyer and Seller for resolution by giving the other
party written notice thereof ("CEO Notice"). The replacement indices selected by
said chief executive officers shall be effective  commencing the month following
the last month for which the Base Contract Price was determined from a published
index or indices,  (the "Index Replacement  Month"), and Seller's statements and
Buyer's payments shall be adjusted accordingly. If said chief executive officers
fail to reach  agreement on or before the  fourteenth  (14th) day  following the
date of the CEO Notice,  either  party may  terminate  this  agreement by giving
written  notice  of  termination  to the other  party,  such  termination  to be
effective upon the expiration of the current  Contract Year. In such event,  the
Base Contract Price for the Index  Replacement  Month and each succeeding  month
for the  remainder of the term shall be  determined  according to the  following
formula:
         Base   Contract Price for the current month = 1.21 x [(A-B) + C] where:
                A = Seller's WASP for the current  month;  B = Seller's WASP for
                the month  immediately  preceding the current month; and C = the
                Base  Contract  Price for the month  immediately  preceding  the
                current month.
8.02 The Base  Contract  Price  shall be billed  each month  based on a two part
(demand/commodity)  rate  design:  twenty-five  percent  (25%)  demand  rate and
seventy-five percent (75%) commodity rate.
              The Demand Bill shall be calculated on a monthly basis as follows:
                (A)(.25)(B) = Demand Bill
         where:
                A = Base Contract Price; and B = DCM multiplied by 30.20.
8.03 The Demand Bill for a month shall be reduced if Seller failed to
     deliver any






quantities of gas  requested by Buyer in  accordance  with Article IV on any day
during the preceding month. Such reduction shall be calculated as follows:
                (A)(.25)(C) =         Amount to be subtracted from the Demand
                                      Bill as otherwise calculated

                where:

                A =   Base Contract Price for the preceding month; and
                C =   Quantities  of gas  requested by Buyer but not delivered
                      by Seller during such month.
8.04  The  Commodity  Bill for a month shall be equal to the  Commodity  Price
multiplied by the total quantity of gas purchased by Buyer hereunder during such
month.  The Commodity Price for a month shall be equal to  seventy-five  percent
(75%) of the Base Contract price for such month.
         An example of the  calculation of the Demand and Commodity  Bills and
adjustments  thereto is outlined in Attachment "A" hereto.
8.05 (a) Either party may initiate a redetermination of the Base Contract Price
and/or the rate design (the "applicable price component(s)") by delivering 
written notice to the other party  on or  before  the  60th  day  prior to the
next Redetermination  Date ("Redetermination  Notice"). If neither party 
receives a Redetermination  Notice on or before such 60th day, the  applicable
price  component(s)  then in effect shall remain in  effect  for the next five
(5) year  period  commencing  on the Redetermination Date.
     (b) If either party receives a Redetermination Notice on or before such
60th day, the parties shall  commence  negotiating in good faith within five (5)
days of such notice to redetermine  the applicable  price  component(s).  If the
parties fail to reach  agreement  within  twenty (20) days of such  notice,  any
remaining  disputed  matters shall be referred to the respective chief executive
officers of Seller and Buyer for resolution.  If said chief  executive  officers
fail to reach  agreement  on or before  the  thirtieth  (30th)  day prior to the
Redetermination Date, either party may terminate this agreement effective on the
Redetermination Date by giving twenty-five (25) days written notice to the other
party.
                                   
                                     ARTICLE IX.
                                   QUALITY OF GAS






9.01 (a) The gas  delivered  hereunder  shall be  merchantable  gas which  shall
comply  with  the  quality   requirements   stated  in  the   tariff(s)  of  the
Transporter(s) transporting the gas purchased and sold hereunder.
     (b) SELLER HAS NO KNOWLEDGE  OF ANY  PARTICULAR  OR SPECIAL  PURPOSE OF
BUYER FOR THE GAS TO BE SOLD HEREUNDER AND MAKES NO WARRANTY WITH RESPECT TO THE
FITNESS OF THE GAS FOR ANY SUCH PURPOSE.

                                     ARTICLE X.
                              METERING AND MEASUREMENT
10.01 The unit of  measurement of the gas shall be one dekatherm of gas. The gas
delivered  hereunder shall be measured and metered by the initial Transporter at
Seller's  sources of gas in accordance with the provisions,  specifications  and
standards set forth in said Transporter's  tariff.  Each party shall preserve or
cause  to be  preserved  for at  least  one (1)  year  all  test  data,  charts,
allocation statements and other similar records available to it, unless a longer
period is prescribed by applicable regulation.

                                    ARTICLE XI.
                                BILLING AND PAYMENT
11.01 On the  first  day of the month  following  the month in which  deliveries
commence  hereunder and on the first day of each month thereafter,  Seller shall
render  to Buyer a  statement  of the  Demand  Bill for the  prior  month.  Such
statement shall include adjustments, if any, which may be calculated pursuant to
Section 8.03.  Buyer shall pay Seller the amount of the Demand Bill statement by
wire transfer to Seller's account at Citibank, N.A. (account number specified on
invoices) on or before the tenth  (lOth) day of each month,  or the tenth (lOth)
day following Buyer's receipt of such statement,  whichever is later;  provided,
however,  if any  payment  date is a  Saturday,  Sunday or legal  holiday,  such
payment  shall be due on the business  day  immediately  following  such payment
date.
11.02 On or before the tenth (lOth) day of each month, Seller shall render
to Buyer a statement  showing the  quantities  of gas delivered by Seller during
the preceding  month and the Commodity Bill therefor,  as well as the amount and
description of any  liquidated  damages owed to Buyer pursuant to Article IV for
the preceding  month.  Buyer shall pay Seller the amount of the  Commodity  Bill
statement by wire transfer to Seller's account at Citibank, N.A. (account number
specified on invoices) on or before the twentieth  (20th) day of each month,  or
the tenth (lOth) day following  Buyer's receipt of such statement,  whichever is
later; provided, however, if any payment date is a






Saturday, Sunday or legal holiday, such payment shall be due on the business day
immediately following such payment date.
11.03 Liquidated damages owed by Sellerfor any month shall be credited against
Buyer's Commodity Bill in the next month and against  Buyer's  Demand Bill and
Commodity  Bill in subsequent  month(s) as necessary.
11.04 If Buyer fails to pay any statement  in whole or in part when due, in 
addition to any other rights and remedies available to Seller, interest at a
rate equal to the prime rate of  Citibank,  N.A. or its  successor  plus 2%
shall accrue on unpaid amounts,  including on unpaid interest  compounded daily,
beginning  on the payment due date of  Seller's  statement  and ending when such
statement is paid. The foregoing  provisions of this Article XI notwithstanding,
if a legitimate, good faith dispute arises between Buyer and Seller concerning a
statement,  Buyer shall pay that portion of the  statement  not in dispute on or
before such due date,  and,  upon the  ultimate  determination  of the  disputed
portion of the statement,  Buyer shall pay Seller the remaining amount owed plus
interest accrued thereon. All disputes regarding quantities delivered to Buyer's
city gate shall be resolved by reference to the  measurement  charts and records
of TGPL at Buyer's  city gate.
11.05 Upon  request,  either party shall mail or deliver  to the  other  party 
for  verification  and  calculation  all  charts, allocation  statements  and 
other documents  used  in the  measurement  of gas delivered  hereunder (to the
extent  such  charts are  available  to the party receiving  such  request)
within ten (10) days after the last  charge for each billing period is received
by Buyer. Such charts,  statements or documents shall be returned to the sender
within thirty (30) days.

                                      ARTICLE XII.
                                     TRANSPORTATION
12.01 Seller will arrange for the  transportation of the gas sold hereunder from
the point(s) of delivery to the Pricing  Point(s) agreed on by Buyer and Seller.
Any  provision in this  agreement to the  contrary  notwithstanding,  as part of
Seller's obligation to arrange such  transportation,  Seller shall indemnify and
hold  Buyer  harmless  from  all  injuries,  claims,  liabilities,  and  damages
irrespective  of the cause thereof (other than Buyer's  negligence)  which arise
out of or in  connection  with  the  gas or the  handling  thereof  during  such
transportation.  
12.02  The gas will be transported  on TGPL from the Pricing Point(s) to Buyer's
city gate under Buyer's FT Agreement.  Buyer shall maintain firm transportation
capacity on TGPL in an amount equivalent to the DCM. To the extent that Buyer
fails to make sufficient firm transportation capacity






on TGPL  available  for the  transportation  of the gas  scheduled  for delivery
hereunder,  and  firm  transportation  is  not  otherwise  available,   Seller's
obligation  to  deliver  such  gas  shall  be  subject  to the  availability  of
interruptible  transportation on TGPL. 
12.03 Buyer and Seller shall cooperate to adjust any discrepancy  among (a) the
quantity  allocated at Seller's sources of gas,  (b) the  quantity  scheduled
by Buyer and (c) the  quantity  allocated as Seller's gas at Buyer's city gate
by the final Transporter.
12.04 Without waiver of any other remedies,  in the event any charges, 
penalties, costs or expenses are incurred or payable to Transporter as a result
of Seller's  failure to give Buyer  timely notice of any  increase or decrease
in daily quantities to be delivered at any point of delivery or  Pricing  Point
from  the quantities nominated and scheduled by Buyer pursuant to Article  IV, 
Seller shall be responsible for such charges, penalties, costs or expenses.
12.05 Without waiver of any other remedies, in the event any charges, penalties,
costs or expenses are incurred or payable to Transporter as a result of Buyer's
failure to give Seller  timely  notice of any  increase or decrease  in daily
quantities to be accepted at any Pricing  Point or at  Buyer's  city gate  from
the quantities nominated and scheduled by Buyer pursuant to Article  IV,  Buyer
shall be responsible  for such  charges,  penalties,  costs or  expenses.
12.06  For the purpose of Sections 12.04 and 12.05, notice will be deemed
timely if, under the circumstances, it should have given the party receiving
such notice reasonably sufficient time to notify  Transporter of such changes
in quantities by the time required  under  the terms of  Transporter's  tariff
to avoid  imposition of a penalty or charge.

                                     ARTICLE XIII.
                               GOVERNMENTAL REGULATIONS
13.01 This agreement shall be subject to all valid applicable state, federal and
local laws,  rules and  regulations;  provided that either party hereto shall be
entitled  to regard all laws,  rules and  regulations  issued by any  federal or
state  regulatory  body as valid and may act in accordance  therewith until such
time as the same may be held  invalid by final  judgment in a court of competent
jurisdiction.  Nothing herein shall be taken to preclude Buyer or Seller or both
from contesting the validity of any such law(s), rule(s) or regulation(s). 
13.02 In the event that the Federal Energy Regulatory Commission ("FERC") or 
any other regulatory  or  governmental  body  asserting  jurisdiction  (i) 
imposes  price controls on natural gas;  (ii)  prohibits  or prevents  any of 
the transactions described in (a) this agreement, (b) any agency






agreement between Buyer and Seller or (c) any  transportation  agreement between
Transporter and Buyer or Seller covering the transportation of the gas delivered
hereunder;  (iii)  otherwise  conditions  such  transactions  in a form  that is
unacceptable in the sole judgment of the party affected thereby;  or (iv) adopts
any action, rule or order which directly or indirectly, materially and adversely
affects the rights or obligations of either party  hereunder (each of the events
described  in (i),  (ii),  (iii) and (iv) being  referred  to herein as "adverse
governmental   action"),   then  the  party  hereto  affected  by  such  adverse
governmental  action may terminate this agreement  effective as of the effective
date of such adverse  governmental  action by giving written notice to the other
and each party shall be held harmless as a result of such termination.

                                    ARTICLE XIV.
                                   FORCE MAJEURE
14.01 No failure or delay in performance, whether in whole or in part, by either
Seller or Buyer shall be deemed to be a breach hereof when such failure or delay
is  occasioned  by or due to any  acts  of  God,  strikes,  lockouts,  or  other
industrial  disturbances,  acts of the public enemy, sabotage,  wars, blockades,
insurrections,  riots, epidemics,  landslides,  lightning,  earthquakes, floods,
storms,  fires,  washouts,  arrests and restraints of rulers and peoples,  civil
disturbances,  explosions,  breakage or accident to  machinery or lines of pipe,
hydrate  obstructions  of lines  of pipe,  lack of  pipeline  capacity  due to a
declared force majeure event experienced by Transporter,  repairs,  maintenance,
improvement,  replacement  or  alterations  to plants,  lines of pipe or related
facilities,  partial or complete  failure to perform by persons  storing gas for
Buyer or  Seller,  inability  of  either  party to obtain  necessary  machinery,
materials or permits or to obtain easements or rights of way, freezing of a well
or delivery  facility,  well  blowouts,  craterings  and the act of any court or
governmental  authority,  or  any  other  cause,  whether  of  the  kind  herein
enumerated or otherwise, not within the control of the party claiming suspension
which,  by the  exercise  of due  diligence,  such party is unable to prevent or
overcome; provided, however, that the settlement of strikes or lockouts shall be
entirely  within the  discretion  of the party  having the  difficulty,  and the
requirement  that any force  majeure  shall be  remedied  with the  exercise  of
diligence  shall not require  the  settlement  of strikes or lockouts  when such
course is  inadvisable  in the  discretion of the party having  difficulty.  Any
proration  or  curtailment  of capacity  under an  interruptible  transportation
agreement shall not constitute a force majeure condition  hereunder.
14.02 Such causes or contingencies affecting the performance of this agreement
by any party hereto, 




however,  shall not relieve  such party of liability in the event of its failure
to use due  diligence  to prevent or overcome  such cause or  contingency  in an
adequate  manner and with all  reasonable  dispatch.  Nor shall  such  causes or
contingencies affecting the performance of this agreement relieve any party from
its  obligations  to make payments of amounts when due. Nor shall such causes or
contingencies  relieve  any party of  liability,  unless  such party  shall give
notice and full  particulars of the same in writing or by telegraph to the other
party as soon as possible after the occurrence  relied on, and like notice shall
be given upon  termination  of such force majeure  conditions.
14.03 If, due to force  majeure,  the  quantities of gas available for delivery
on any day at a Pricing Point are insufficient to meet all of Seller's firm
sales obligations at such point, then Buyer shall be entitled to receive such
proportion of the total deliveries  which  Seller  is  able  to effect  at such
point (including any quantities  of gas  deliverable  by Seller to such point
pursuant to Seller's interruptible  transportation from TGPL Zones 1, 2 and 3)
as Buyer's  Nominated Quantity for such point bears to the sum of the nominated
quantities under this agreement and Seller's other firm sales contracts for such
point. In such event, deliveries to Buyer hereunder of its full Nominated
Quantity shall have priority over all sales of gas by Seller under interruptible
sales contracts at such point.

                                   ARTICLE XV.
                                WARRANTY OF TITLE
15.01 Seller warrants title to all gas delivered by it, that it has the right to
sell or  deliver  the same,  and that such gas is free  from  liens and  adverse
claims of every kind.  Seller  shall pay or cause to be paid all taxes and other
sums due on the gathering  and handling of the gas  delivered by Seller.  Seller
shall  indemnify and save Buyer  harmless  from and against all suits,  actions,
damages, costs and expenses arising from or out of any breach of this provision.

                                   ARTICLE XVI.
                                 RESPONSIBILITY
16.01 As between the parties  hereto,  Seller shall be deemed to be in exclusive
control  and  possession  of the gas  sold  hereunder  until  such  gas has been
delivered to the  point(s) of delivery,  after which point Buyer shall be deemed
to be in exclusive control and possession of such gas.
16.02 The party deemed to be in control and possession of the gas sold hereunder
shall be responsible for and shall indemnify the other party with respect to any
claims,  liabilities or damages  arising  therefrom  when  such  gas  is in 
that party's control and possession.







                                  ARTICLE XVII.
                               GENERAL PROVISIONS
17.01  Copies of any filing  submitted  to the FERC,  or to any state or federal
