                           GAS TRANSPORTATION SERVICE

    1. Subject to the terms and  provisions  of this  agreement  and of Seller's
Rate Schedule IT, Buyer agrees to deliver or cause to be delivered to Seller gas
for transportation and Seller agrees to receive, transport and redeliver natural
gas to Buyer or for the account of Buyer,  on an  interruptible  basis,  up to a
maximum daily quantity of 300,000 DT per day. Seller, after having satisfied any
pending  requests  for  service  under Rate  Schedule  IT, may  transport  daily
quantities  of gas tendered by Buyer in excess of the  specified  maximum  daily
quantity;  however,  in no event  shall  Seller be  obligated  to receive at any
point(s)  of  receipt a quantity  of gas in excess of the lower of  Buyer's  (1)
maximum  daily  quantity plus  compressor  fuel and line loss make-up or (2) the
daily quantity  scheduled for delivery to Seller.  Nor shall Buyer tender at any
one or all point(s) of receipt a cumulative quantity of natural gas in excess of
such daily quantity without the prior consent of Seller.

    2. Transportation service rendered hereunder shall be subject to curtailment
or interruption  when in Seller's  judgment such  curtailment or interruption is
necessary  due  to  operating  conditions  or  insufficient   pipeline  capacity
available on Seller's system,  or is otherwise  necessary to protect  authorized
firm  services.  In the event  Seller is unable to receive or deliver  the total
quantity of natural gas  requested to be  transported  for all Buyers of service
under Rate Schedule IT, then seller shall allocate available capacity among such
Buyers in accordance  with Section 6 of Seller's Rate Schedule IT and Section 28
of the General Terms and Conditions of Seller's FERC Gas Tariff.

                                   ARTICLE II

Buyer  shall  deliver or cause to be  delivered  gas at the  point(s) of receipt
hereunder at a pressure  sufficient to allow the gas to enter Seller's  pipeline
system at the varying pressures that may exist in such system from time to time;
provided,  however,  that such  pressure  of the gas  delivered  or caused to be
delivered  by Buyer shall not exceed the maximum  allowable  operating  pressure
specified below.

point(s) of receipt hereunder, is from time to time increased or decreased, then

Buyer to Seller at the point(s) of receipt shall be correspondingly increased or
decreased.  The point(s) of receipt for natural gas received for  transportation
pursuant to this  agreement  shall  include all  available  points of receipt on

request log program required by Commission Regulation 250.16(b)(2).
