         B.      Shipper owns or controls certain supplies of natural gas which

of the regulations of the Federal Energy Regulatory Commission ("FERC").

         C.      Shipper has made a complete written request to Transporter for
the transportation service described herein on February 10, 1989.

set forth herein, the parties agree as follows:

                  ARTICLE I - GAS DELIVERIES AND REDELIVERIES

         1.1     Subject to the terms, conditions and limitations hereof,

Exhibit A herein, transport and deliver to Shipper at the Delivery Point(s)
specified in Exhibit B herein, the following quantities of natural gas, known
as Transportation Contract Demand:

         Up to 32,800 MMBtu's/day provided that Transporter's receipt of gas at
any receipt point for Shipper's account hereunder on any day shall not exceed
the maximum daily quantity set forth for such receipt point on Exhibit "A"
hereto, and provided that Transporter's daily obligation to deliver gas to
Shipper at any delivery point under this Transportation Agreement shall not

and Conditions applicable to this Agreement, Shipper has elected to furnish
fuel and lost or unaccounted for gas volumes in-kind. Transporter may receive
volumes of gas in excess of the maximum daily quantity set forth in Section 1.1
when necessary to cover such fuel gas reimbursement while making full delivery

by the parties.

         1.3  Such transportation shall be on a firm basis.
   2

         3.5      (Section 3.5 shall be applicable only for the transportation

it or its buyer or seller is the "importer of record" and it will comply with
all requirements for reporting and submitting payment of duties, fees, and
taxes to the United States or agencies thereof to be made on imported natural
gas and for making the declaration of entry pursuant to 19 CFR Section 141.19.
Shipper agrees to indemnify and hold Transporter harmless from any and all
claims of damage or violation of any applicable laws, ordinances and statutes
which pertain to the importation of the gas transported hereunder and which
require reporting and/or filing of fees in connection with said import.

                               ARTICLE IV - TERM

         4.1     This Agreement becomes effective the date first written above
and shall remain in full force and effect until October 31, 2004 and year to
year thereafter, subject to termination by either party either at the
expiration of the primary term or upon any anniversary thereafter by giving
written notice so stating to the other party at least twelve (12) months in
