          The undersigned, Longview Fibre Company ("Fibre") and Cascade Natural
Gas Corporation ("Cascade"), are parties to the Agreement for Peaking Gas
Service dated as of March 22, 1991 ("PGS Agreement").  The parties have
disagreed over the amount properly payable by Cascade to Fibre for service under

          In the interest of compromise and settlement, the parties have entered
into this Settlement Agreement to resolve their differences without need for
arbitration or litigation.  This Settlement Agreement is a compromise reached
between the parties after negotiation relating to pricing to the service
rendered and to be rendered by Fibre to Cascade under the PGS Agreement.  The
applicable period of agreement for the PGS Fee is from October 1996, to
September 30, 2001.

          The parties agree as follows:

          1.   The settlement proposal of Fibre to Cascade contained in its
September 4, 1997, letter, a copy of which is attached hereto as Exhibit A and
incorporated herein by this reference, is agreed to by the parties with one
correction.  On page 2, next to last paragraph, the ending time for the reduced
PGS fee is to be the Contract Year October 2000 to September 2001.  This
correction is noted on Exhibit A.

          2.   In order to implement this agreement, the PGS Agreement will be
amended in the form attached as Exhibit B.

          This Settlement Agreement is entered into as of the date first set
forth above.

Mr. King Oberg                               PRIVILEGED AND 
Vice President, Gas Supply                   CONFIDENTIAL;
Cascade Natural Gas Corporation              FOR SETTLEMENT PURPOSES 
222 Fairview Avenue North                    ONLY
Seattle, WA  98109

Dear King:

This letter is in response to (1) the proposal of Cascade Natural Gas
("Cascade") to adjust the annual fee under the Agreement for Peaking Gas Service
("PGS") between Longview Fibre Company ("Fibre") and Cascade from $970,350.00 to
$708,894.44 beginning the  October 1996 to September 1997 period, and (2) your
August 8 reply to our letter expressing concerns with your proposal.

At the outset, Fibre must respectfully point out that the storage service is not
comparable to the PGS.  Although Cascade can change the scheduled quantity for
withdrawals from storage up to four times per day, Cascade can make up to 6
changes (initiating or terminating) and up to 12 changes (rate of taking) per
day under the PGS.  Moreover, in order to effect delivery of the storage gas to
the city gate, Cascade must comply with the transportation nomination procedures
of Northwest, which in all cases do not assure that Cascade can arrange for
delivery of the storage gas on 4 hours' notice or change the rate of delivery of
the storage gas on 2 hours' notice as Cascade can under the PGS.  The 4-hour and
2-hour notice provisions of the PGS are features that Fibre does not believe can
be duplicated by other alternative peaking services, especially not the storage
service obtained by Cascade.

Furthermore, Fibre respectfully disagrees with the methodology used in Cascade's
proposal.  Under the Agreement for PGS, the annual fee is adjusted "to ensure
the PGS fee is COMPARABLE to the least cost alternative sources of peaking
service reasonably available to Cascade."  As set forth in detail below, Fibre
does 

<PAGE>

not believe that the $708,894.44 figure proposed by Cascade represents a
comparable level of the full costs to Cascade for the storage service received
through Washington Water Power.

First, once Cascade withdraws 192,000 dekatherms of its gas in storage, Cascade
can no longer receive 15, 000 dt/day of gas as it does under the PGS.  To adjust
the features of the storage service to make them comparable to the PGS, Cascade
would have to either (1) obtain 405,000 additional dekatherms of annual storage
service, or (2) inject quantities into storage during the winter season.  Fibre
believes that the first option would increase Cascade's storage costs by at
least $588,912.00 per year, while the second option would increase the costs by
at least $229,608.00 per year.

Second, under the storage service, Cascade incurs a cost of carrying the gas
held in storage until it is delivered.  Fibre calculates this cost to be at
least $43,815.67 per year.

Third, Fibre believes that the cost to Cascade of the fuel charges for storage
withdrawals and in transporting gas from storage were omitted.  Fibre calculates
these charges to be at least $23,066.44 per year.

Fourth, Cascade did not calculate any costs for transporting gas to storage. 
Fibre calculates this cost to be at least $172,339.07 per year.

If the costs referred to above are added, the full costs of the storage service
received by Cascade would be at least $1,273,324.90 per year:

                                                  OPTION A        OPTION B

                                       Total   $1,632,628.90    $1,273,324.90
    

DESPITE THE FOREGOING, WITHOUT PREJUDICE TO FIBRE'S POSITION IN ANY ARBITRATION
(AND OTHER POSSIBLE PROCEEDING) AND IN A GOOD FAITH EFFORT TO REACH SETTLEMENT
OF THIS MATTER, FIBRE MAKES THE FOLLOWING NON-SEVERABLE SETTLEMENT OFFER:

<PAGE>

-    the PGS fee would be reduced to $708,984.44 per year;

-    the reduced PGS fee would be applicable starting with the contract year
     October 1996 to September 1997 and ending for the contract year October
     2001 to September 2002;

-    amend the Peaking Gas Service Agreement to reflect the new five year firm
     price with the option to renegotiate should gas and/or transportation rate
     increase, affecting the agreement with Cascade's Washington Water Power
     Storage Agreement; and

-    Cascade would provide Fibre with the following fuel management services for
     the remaining term of the Agreement for PGS:

     -    an aggressive program, with daily consultations between 
          Cascade and Fibre, to release any part of the 48,000 
          dt/day of capacity on Northwest Pipeline for which Fibre 
          currently pays the reservation fees and which is not 
          needed by Fibre, with the proceeds from such releases 
          going to Fibre;

     -    an aggressive program, with daily consultations between 
          Cascade and Fibre, to resale any part of the 18,000 
          dt/day of natural gas (or additional supplies purchased 
          by Fibre) which Fibre currently buys from Duke or other 
          supplier and which is not needed by Fibre, with the 
          revenue from such resale going to Fibre;

     -    an aggressive program, with daily consultations between Cascade and
          Fibre, to purchase gas at locations agreed to by Cascade and Fibre and
          to have such gas delivered to Fibre; 

     -    monthly reporting of the savings to Fibre under the above-stated
          programs; and

     -    monthly balancing and reporting of all gas and transportation
          activities related to Fibre.

If Cascade agrees with this settlement offer, please prepare and forward the
appropriate documents.  If you have any questions regarding the above, do not
hesitate to contact me.
