Contract  Quantity,  as provided in Section 5.1, that Party shall be liable for,
and shall pay the other party, the following damages:

          (a) Buyer's  Failure.  If the quantity Buyer receives and purchases on
     any Day is less than the applicable  Contract  Quantity and the Sales Price
     is less than the Contract  Price,  then Buyer shall be liable for and shall
     pay to Seller a dollar  amount  equal to the product of (i) the  difference

     ten percent (10%) of the amount  calculated  pursuant to the first sentence

     costs and expenses.



          (b) Seller's Failure. If the quantity Seller sells and delivers on any
     Day is less than the applicable Contract Quantity and the Replacement Price
     is greater  than the  Contract  Price,  then Seller shall be liable for and
     shall  pay to  Buyer  a  dollar  amount  equal  to the  product  of (i) the
     difference  between the Replacement  Price and the Contract Price and; (ii)
     Seller's Deficiency Quantity. In addition, Seller shall pay Buyer an amount
     equal to ten percent (10%) of the amount  calculated  pursuant to the first
     sentence  of  this  subsection  (b) to  cover  Buyer's  administrative  and
     operational costs and expenses.

     purchase  or sale,  the failing  Party shall still be liable in  accordance

     shall be deemed to be the daily price as posted in BTU's Daily Gas Wire for
     Gas for each day to failure at the location which most closely reflects the
     relevant Delivery  Point(s);  provided,  however,  if the non-failing party
     does not learn of the  failure  until  after the fact,  then in lieu of the
     remedy provided in this subsection (c), the non-failing party may calculate
     its damages as of the date(s) on which  replacement  purchases or sales are
     actually made.

7.2  EFP  and  Trigger  Price  Transactions.   If  the  Transaction  is  an  EFP
Transaction,  any Party  failing to offer and  complete  the purchase or sale of
Exchange  futures  contracts  from or to the other  Party shall be liable to the
other  Party for actual  losses  incurred by it due to such  failure.  If either
Party  fails to complete  the  purchase or sale of gas after the other Party has
executed  trades  pursuant to Section 6.2 Trigger Price,  then the failing Party
shall be liable to the  non-failing  Party for an actual losses incurred for the
reversal of trades so  executed.  Calculation  of any  damages  pursuant to this
Section 7.2 shall be incorporated as necessary in the calculation of damages set
forth  in  Section  7.1 to  assure  that  the  non-failing  Party  will be fully
compensated for its actual loss incurred because of the other Party's failure.

     offsetting  the total  amount  each party owes to the other  Party shall be
     paid by the Party owing the greater amount, no later than the Payment Date.

          (b) If either Party, in good faith, disputes the amount of any invoice
     or  portion of any  invoice in the  current  billing  month,  then only the
     non-disputed portion of the invoice(s) will be subject to netting according
     to  this  Article  IX.  The   disputing   Party  must  provide   supporting
     documentation acceptable in industry practice to support the amount paid or
     disputed.  Upon  resolution  of such  dispute,  any  amounts  owing will be
     included in netting procedures in the subsequent month.
