Item 5.  Other Events and Regulation FD Disclosure

EARNINGS FOR FOURTH QUARTER, TWELVE MONTHS ENDED DECEMBER 31, 2002

     On February 4, 2003, Northwest Natural Gas Company ("NW Natural" or the
"Company"), reported consolidated earnings applicable to common stock of $41.5
million for the fiscal year ended Dec. 31, 2002, compared to $47.8 million in
2001. Earnings in 2002 were $1.62 a diluted share compared to earnings of $1.88
a diluted share in 2001.

     For the quarter ended Dec. 31, 2002, NW Natural's consolidated earnings
applicable to common stock were $17.8 million, compared to $23.8 million for the
fourth quarter of 2001. Earnings for the fourth quarter were 69 cents a diluted
share, down from 93 cents a diluted share in 2001. Temperatures in NW Natural's
service area in the Pacific Northwest were 13 percent warmer than average in
December, reflecting the El Nino weather pattern in place in the western U.S. in
the early part of the winter.

     Fourth Quarter Detail

     Total gas deliveries in the fourth quarter of 2002 were 326 million therms,
down about 1 percent from 2001. Total utility margin before allowances for
demand charges and other items was $106 million, 5 percent lower than $111
million in 2001.

     Sales to residential and commercial customers in the fourth quarter of 2002
were 189 million therms, down 5 percent from 2001 due to warmer weather. Weather
for the fourth quarter of 2002 as a whole was 6 percent warmer than average and
3 percent warmer than in 2001. The Company estimates that the warm weather and
other factors affecting consumption reduced sales to residential and commercial
customers in the fourth quarter of 2002 by 15 million therms and reduced margin
by $5.5 million, equivalent to 13 cents a share.

         Gas deliveries to industrial and electric generation customers in the
fourth quarter of 2002 were 137 million therms, up from 132 million therms in
2001. Margin in these sectors in the fourth quarter was $9.7 million, down from
$13.5 million in 2001. Results in 2001 included margin from the market for
electric generation totaling $2.1 million, equivalent to 5 cents a share.
Contracts with two electric generation customers expired as of June 30, 2002.

     Earnings from gas storage services in the fourth quarter of 2002 were $1.2
million, equivalent to 4 cents a share, compared to $0.7 million or 3 cents a
share in the fourth quarter of 2001. NW Natural provides gas storage services to
customers in the interstate market from its Mist gas storage field, using
storage capacity that has been developed in advance of core utility customers'
requirements. For reporting purposes, the Company has classified its interstate


                                       2



gas storage services as a separate business segment from its traditional gas
utility operations.

     NW Natural has a Purchased Gas Adjustment (PGA) tariff in Oregon under
which it absorbs 33 percent of any excess cost of gas, or retains 33 percent of
any savings, both as compared to the gas commodity prices built into rates.
Fourth quarter results in 2001 included a 33 percent share of the savings
realized from NW Natural's gas commodity purchases during the quarter. The
savings contributed $5.2 million of margin, equivalent to 12 cents a share of
earnings. The equivalent results under the sharing mechanism in the fourth
quarter of 2002 were an absorption of $0.4 million of excess costs, equivalent
to 1 cent a share.

     Consolidated operations and maintenance expenses in the fourth quarter of
2002 were $23.0 million, down slightly from the fourth quarter of 2001,
reflecting cost controls. The overall reduction from the 2001 expense level was
achieved despite significant increases in pension and health care expenses.

     Fiscal Year Detail

     NW Natural earned $1.76 a diluted share from traditional utility operations
in 2002, the same as the result from utility operations in 2001. In addition,
the Company earned 14 cents a share in 2002 from interstate gas storage
operations and 5 cents a share from subsidiary and other non-utility operations,
primarily a subsidiary that has investments as a limited partner in several
alternative electric generating projects in California. The charges to
non-utility operations relating to NW Natural's effort to purchase Portland
General Electric Company from Enron Corp. were equivalent to 33 cents a diluted
share. The results from non-utility operations in 2002 compared to earnings of 8
cents a share from interstate gas storage and 4 cents a share from subsidiary
and other non-utility operations in 2001.

     NW Natural's total gas deliveries in 2002, excluding deliveries of gas
stored for others, were 1.126 billion therms, up slightly from 2001. Total
utility margin before allowances for demand charges and certain other items was
$345 million, up 4 percent from $333 million in 2001.

     Gas sales to residential and commercial customers in 2002 were 591 million
therms, about the same as in 2001. Weather in 2002 was very close to average for
the year as a whole but was 2 percent warmer than 2001.

     Sales to residential and commercial customers in 2002 reflected lower
consumption patterns by customers which the Company believes are due to higher
gas commodity prices reflected in rates in previous years. Almost all of the
effects of the lower consumption patterns on margin and earnings were felt in
the first nine months of the year. Effective Oct. 1, 2002, the Company
implemented rate increases designed to recoup the margin lost due to the changes
in consumption patterns. These rate increases, which will continue in effect in


                                       3



2003, contributed approximately 10 cents a share to earnings in the fourth
quarter of 2002.

     Margin from the residential and commercial market sectors in 2002 was $299
million, up 5 percent from $285 million in 2001. NW Natural had 560,067
customers at year-end 2002, up 3.5 percent from year-end 2001. The Company
estimates that customer growth contributed 17 million therms to sales volumes
and $8.1 million to margin revenues during 2002.

     Gas deliveries to industrial and electric generation customers in 2002 were
535 million therms, up 1 percent from 2001. Margin from sales and transportation
in these markets was down about 6 percent from 2001, however, at $45.3 million
compared to $48.0 million. Both year's results include the effects of contracts
for service to electric generation customers that contributed margin equivalent
to 11 cents a share in each year's earnings.

     NW Natural earned $3.6 million from interstate gas storage services in
2002, equivalent to 14 cents a share, compared to $2.1 million or 8 cents a
share from storage services in 2001.

     NW Natural's share of the savings realized from its gas commodity purchases
in 2002 under the PGA mechanism in Oregon contributed $10.8 million of margin
for the year, equivalent to 26 cents a share of earnings. The equivalent result
from NW Natural's share of gas cost savings in 2001 was a margin contribution of
$4.1 million, generating 10 cents a share of earnings.
