   7. QUALITY
   
     7.1  Heat Content.  Heat content shall mean the gross heating value
          per cubic foot of Gas received or delivered hereunder.  Such
          Gas shall have a heat content not less than 950 BTU per cubic
          foot when determined on a dry basis.  Seller shall have the
          right to waive such BTU content limits if, in Sellers sole
          opinion, Seller is able to accept Gas with a BTU content
          outside such limits without affecting Sellers operations.
          The total heating value per cubic foot of Gas shall be
          determined by one of the following methods:
   
          (a)  by means of an instrument of standard manufacture
               installed to measure the heating value of the Gas.
   
          (b)  at intervals of not more than six (6) Months by means of
               an instrument of standard manufacture and a sample of Gas
               from the Gas stream.
   
          (c)  other method mutually agreed upon by both parties.
   
          For the purpose of calculating injections and withdrawals, the
          heat content of the Gas so determined at each such point shall
          be deemed to remain constant at such point until the next
          determination.  The unit of quantity for the purpose of
          determining total heating value shall be one (1) cubic foot of
