ITEM 5.  OTHER EVENTS

In addition to presenting results of operations and earnings amounts in total,
Northwest Natural Gas Company ("NW Natural" or the "Company") has expressed
certain measures herein in cents per share on a diluted basis (see Note 1 in the
Company's 2002 Form 10-K). These amounts reflect factors that directly impact
the Company's earnings. The Company believes this per share information is
useful because it enables readers to better understand the impact of these
factors on the Company's earnings.

EARNINGS FOR FOURTH QUARTER, TWELVE MONTHS ENDED DECEMBER 31, 2003
------------------------------------------------------------------

NW Natural reported consolidated earnings applicable to common stock of $45.7
million for the fiscal year ended Dec. 31, 2003, compared to $41.5 million in
2002. Earnings in 2003 were $1.76 a diluted share, compared to earnings of $1.62
a diluted share in 2002. The results for 2002 included charges equivalent to 33
cents a share relating to a terminated acquisition.

For the quarter ended Dec. 31, 2003, NW Natural's consolidated earnings
applicable to common stock were $21.7 million, up 22 percent from $17.8 million
in the fourth quarter of 2002. Earnings for the fourth quarter were 83 cents a
diluted share, up from 69 cents a diluted share last year.

In 2003, NW Natural grew its customer base by more than 3 percent adding 18,083
customers to its gas distribution system during the year. The Company also
increased earnings from its business segment for interstate gas storage services
from 14 cents a share in 2002 to 17 cents a share in 2003, secured a permit for
the construction of a major extension of its pipeline from the Mist Storage
Field to the Portland metropolitan area and completed the first 11.7-mile
segment of the pipeline, below budget and on time for the 2003-04 heating
season.

NW Natural completed its general rate case in Oregon with a result that included
phased rate increases, the recovery of costs relating to its gas storage
investments and higher operating expenses, and the approval of a new weather
normalization mechanism.

Fourth Quarter Detail
---------------------

Total gas deliveries in the fourth quarter were 350 million therms, up 7 percent
from last year. Net utility margin, after allowances for demand charges and
other items, was $89.4 million, 12 percent higher than last year's $80.0
million.

Sales to residential and commercial customers in the fourth quarter of 2003 were
204 million therms, up 8 percent from last year despite slightly warmer weather.
Weather for the fourth quarter was 7 percent warmer than average and 1 percent
warmer than last year. The Company's new weather normalization mechanism in
Oregon contributed $2.1 million of margin in the fourth quarter, equivalent to 5
cents a share, making up a significant portion of the weather-related margin
loss. The mechanism was not effective until the middle of October, a month that


                                       2



was 28 percent warmer than average in NW Natural's service area (measured in
degree-days) and 34 percent warmer than last year.

Gas deliveries to industrial and electric generation customers in the fourth
quarter were 146 million therms, up 6 percent from 137 million therms last year.
Margin in these sectors in the fourth quarter was $10.1 million, up from $9.7
million last year. The higher deliveries and margin in the industrial market in
the fourth quarter primarily reflect the addition of a large new customer and
some rate design changes approved in the Oregon general rate case.

Earnings from NW Natural's gas storage business segment in the fourth quarter of
2003 were $0.9 million, equivalent to 3 cents a diluted share, compared to $1.2
million or 4 cents a share in the fourth quarter of 2002. These results include
income from interstate gas storage services as well as income from a contract
with an independent trading company that seeks to optimize the use of NW
Natural's assets by trading temporarily unused portions of its gas storage
capacity and upstream pipeline transportation capacity. 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. Results from the gas storage segment were higher in the
fourth quarter of 2002 due to a larger contribution of income in that quarter
from the asset optimization contract.

NW Natural completed the first phase of its South Mist Pipeline Extension
(SMPE), an 11.7-mile segment from the Molalla gate station on the Williams-West
interstate pipeline system to a point near Aurora, Ore., and put it into service
in mid-November. Results for the fourth quarter include $0.6 million of deferred
revenues for the recovery of costs relating to this pipeline segment, pursuant
to the treatment of the SMPE in NW Natural's Oregon general rate case.

Fiscal Year Detail
------------------

NW Natural earned $1.57 a diluted share from utility operations in 2003,
compared to $1.76 a share from utility operations in 2002. In addition, the
Company earned 17 cents a diluted share in 2003 from interstate gas storage
operations, up from 14 cents a share in 2002; and 2 cents a diluted share from
subsidiary and other non-utility operations, compared to a loss of 28 cents a
share in 2002. The loss from non-utility operations in 2002 included charges
equivalent to 33 cents a diluted share relating to NW Natural's effort to
purchase Portland General Electric Company from Enron.

NW Natural's total gas sales and transportation deliveries in 2003, excluding
deliveries of gas stored for others, were 1.1 billion therms, down 2 percent
from 2002. Net utility margin, after allowances for demand charges and other
items, was $279 million, about the same as last year.

Gas sales to residential and commercial customers in 2003 were 582 million
therms, down about 1 percent from 2002. Weather in 2003 was 6 percent warmer
than average and 7 percent warmer than 2002.


                                       3



Margin from the residential and commercial market sectors was $309 million, up 3
percent from $299 million in 2002. The negative impact of warmer weather was
more than offset by the effects of rate increases and customer growth. The
higher margin in 2003 reflects the full-year impact of rate increases effective
in Oregon on Oct. 1, 2002, designed to recoup the margin lost due to changes in
customers' consumption patterns. The higher margin also reflects rate increases
effective Sept. 1, 2003, resulting from NW Natural's general rate case in
Oregon. NW Natural had 578,150 customers at year-end 2003, up 3.2 percent from
year-end 2002. The Company estimates that customer growth contributed 16 million
therms to sales volumes and $6.7 million to margin revenues during the year.

Gas deliveries to industrial and electric generation customers in 2003 were 518
million therms, down 3 percent from last year. Margin from sales and
transportation in these markets was $37.7 million, down about 17 percent from
last year. Results for 2003 reflect weak economic conditions early in the year,
but also some cost-related changes in the design of industrial rates in the
Oregon general rate case that reduced industrial margins. Results in 2002
included $4.5 million of margin, equivalent to 11 cents a share of earnings,
from contracts for service to electric generation customers that expired at
mid-year 2002.

NW Natural earned $4.3 million from its gas storage business segment in 2003,
compared to $3.6 million in 2002. In both cases the income is net of amounts
shared with core utility customers.

NW Natural's partial decoupling mechanism in Oregon contributed $3.5 million of
margin in 2003, equivalent to 8 cents a diluted share of earnings, compared to
$1.7 million of margin or 4 cents a share in 2002. The decoupling mechanism,
approved by the Public Utility Commission of Oregon in the fall of 2002 as part
of NW Natural's Conservation Tariff, was designed to recover lost margin due to
changes in residential and commercial consumption patterns.

NW Natural has a Purchased Gas Adjustment 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. The
Company also retains 33 percent of the margin when it sells surplus gas
commodity off-system, distributing 67 percent to its customers. NW Natural's
share of the commodity savings and off-system margin realized from its gas
purchasing program in 2003 contributed $5.2 million of margin for the year,
equivalent to 12 cents a diluted share of earnings. Last year these factors
contributed $11.7 million of margin, equivalent to 28 cents a share of earnings.

Operations and maintenance expenses in 2003 were up $11.3 million, or 13
percent, over last year. The increase in O&M expenses included higher pension
expense as determined under Statement of Financial Accounting Standards (SFAS)
No. 87 ($3.1 million), as well as higher costs for health benefits ($0.9
million) and business risk insurance premiums ($0.9 million). The higher
expenses in these three categories reduced earnings for the year by about 12
cents a share as compared to the equivalent expenses in 2002. Expenses in these
categories at approximately their current levels were included in expenses for
ratemaking purposes in NW Natural's Oregon general rate case.
