          Northwest Natural Gas Company, a body corporate having
          an office in the City of Portland, in the State of
          Oregon (hereinafter referred to as "Customer")

IN CONSIDERATION of the premises and the covenants and agreements
herein contained, the parties hereto covenant and agree as
follows:

1.   Customer acknowledges receipt of a current copy of Company's
     Gas Transportation Tariff (the "Tariff").

2.   The terms used herein shall have the same meanings as are
     ascribed to corresponding terms in the General Terms and
     Conditions contained in the Tariff, unless otherwise defined
     herein.

3.   Customer hereby requests, and Company agrees to provide,
     Service pursuant to Rate Schedule FS in accordance with the
     attached Schedules of Service, such Service to commence on
     the Billing Commencement Date and to terminate, subject to
     the provisions hereof, on the Service Termination Date. 
     Company shall include on Customer's Index of Service for
     Rate Schedule FS the Service to be provided hereunder and
     Customer agrees to acknowledge such Index of Service from
     time to time at Company's request.

4.   Customer agrees to pay to Company each Billing Month, for
     all Service rendered under this Service Agreement, an amount
     equal to the aggregate charge for Service described in
     paragraph 4.5 of Rate Schedule FS.

5.   Customer shall:

     (a)  provide such assurances and information as Company may
          reasonably require respecting any Service to be
          provided pursuant to this Rate Schedule FS including,
          without limiting the generality of the foregoing, an
          assurance that necessary arrangements have been made
          among Customer, producers of gas for Customer,
          purchasers of gas from Customer and any other Person
          relating to such Service, including all gas purchase,
          gas sale, operating, processing and common stream
          arrangements; and

     (b)  at Company's request provide Company with an assurance
          that Customer has provided the Person operating
          facilities upstream of any Receipt Point in respect of
          which Customer has the right to receive Service with
          all authorizations necessary to enable such Person to
          provide Company with all data and information
          reasonably requested by Company for the purpose of
          allocating volumes of gas delivered to Company among
          Company's Customers and to bind Customer in respect of
          all such data and information provided.  

     If Customer fails to provide such assurances and information
     forthwith following request by Company, from time to time,
     Company may at its option, to be exercised by notice to
     Customer, suspend the Service to which such assurances and
     information relate until such time as Customer provides the
     assurances and information requested, provided however that
     any such suspension of Service shall not relieve Customer
     from any obligation to pay any rate, toll, charge or other
     amount payable to Company.

6.   Customer acknowledges that the Facilities have been designed
     to provide for the transportation of the aggregate gas
     supply that is forecast to be received at Receipt Points on
     the NOVA system, as described each year in NOVA's Annual
     Plan, and that interruption and curtailment of Service may
     occur if the aggregate gas supply actually received at such
     Receipt Points is greater than forecast.
