ITEM 1. BUSINESS

General
- -------

         Northwest Natural Gas Company (NW Natural or the Company) was
incorporated under the laws of Oregon in 1910. The Company and its predecessors
have supplied gas service to the public since 1859. Since September 1997, it has
been doing business as NW Natural.

         NW Natural is principally engaged in the distribution of natural gas.
The Oregon Public Utility Commission (OPUC) has allocated to NW Natural as its
exclusive service area a major portion of western Oregon, including the Portland
metropolitan area, most of the fertile Willamette Valley and the coastal area
from Astoria to Coos Bay. NW Natural also holds certificates from the Washington
Utilities and Transportation Commission (WUTC) granting it exclusive rights to
serve portions of three Washington counties bordering the Columbia River. Gas
service is provided in 95 cities, together with neighboring communities, in 16
Oregon counties, and in nine cities, together with neighboring communities, in
three Washington counties. Based on U.S. Census Bureau statistics for 1995, NW
Natural's service areas had a population of about 2,735,000, including about 78
percent of the population of the State of Oregon and 6 percent of the population
of the State of Washington. The City of Portland, Oregon is the principal retail
and manufacturing center in the Columbia River Basin. It is a major port and
growing nucleus for trade with Pacific Rim nations such as Japan, Taiwan and
Korea.

         At year-end 1997, NW Natural had about 407,100 residential customers,
50,300 commercial customers and 600 industrial customers. Industries served
include pulp, paper and other forest products; the manufacture of electronic,
electrochemical and electrometallurgical products; the processing of farm and
food products; the production of various mineral products; metal fabrication and
casting; and the production of machine tools, machinery and textiles.

         The Company has two active wholly-owned subsidiaries.  NNG Financial
Corporation (Financial Corporation) is incorporated in Oregon. Canor Energy
Ltd. (Canor) is incorporated in Alberta, Canada.

         Financial Corporation arranges short-term financing for Canor and holds
financial investments as a limited partner in three solar electric generating
plants, four windpower electric generation projects and a hydroelectric project,
all located in California, and in two low-income housing projects in Portland.
Financial Corporation also holds interests in certain gas producing properties
in the western United States (See Item 2, Properties, below).

     Canor is engaged in natural gas and oil exploration, development and
production in Alberta and Saskatchewan, Canada. Since 1995, Canor has managed a
joint venture with a wholly-owned subsidiary of NIPSCO Industries, Inc.
(NIPSCO), to develop gas and oil properties in western Canada. Canor and NIPSCO
plan to amalgamate their respective operations into a new company during 1998.

Gas Supply - General
- --------------------

         NW Natural meets the needs of its core market (residential, commercial
and firm industrial) customers through natural gas purchases from a variety of
suppliers. NW Natural has a diverse portfolio of short-, medium- and long-term
firm gas supply contracts. During periods of peak demand, supplies under these
contracts are supplemented with gas from storage facilities either owned by or
contractually committed to NW Natural.

         Natural gas for NW Natural's core market is transported by Northwest
Pipeline Corporation (NPC), primarily under three firm transportation
agreements. NPC's rates for service under these agreements are established by
the Federal Energy Regulatory Commission (FERC) under NPC's primary firm
transportation rate schedule, as amended or superseded from time to time.

         The largest of the contracts with NPC expires September 30, 2013 and
provides for firm transportation capacity of up to 2,160,440 therms(1) per day.
This agreement provides access to natural gas supplies in British Columbia and
the U.S. Rocky Mountains.

         NW Natural also has a contract with NPC expiring September 30, 2009 for
340,000 therms per day of firm transportation capacity for the Company's core
market. This agreement also accesses gas supplies in the U.S. Rocky Mountain
region.

         The third transportation contract with NPC, under which service
commenced on December 1, 1995 and expires November 30, 2011, provides 1,020,000
therms per day of firm transportation capacity from the point of interconnection
of the NPC and PG&E Gas Transmission Northwest (PG&E GT-NW, formerly Pacific Gas
Transmission) systems in eastern Oregon to NW Natural's service territory. PG&E
GT-NW's pipeline runs from the U.S./Canadian border through northern Idaho,
southeastern Washington and central Oregon to the California/Oregon border. NW
Natural's total capacity on PG&E GT-NW and two other upstream pipelines (Alberta
Natural Gas Company and NOVA Corporation of Alberta) substantially matches this
amount of NPC capacity northward into Alberta, Canada.

         The cost to NW Natural of gas to supply its core market consists of the
purchase price paid to suppliers plus charges paid to pipelines to transport
such gas to NW Natural's distribution system. While the rates for pipeline
transportation and peaking services are subject to federal regulation, the
purchase price of gas is not. Although pipeline rates increased significantly in
1993 due to system expansion and rate design changes, the effect of such
increases on core market customers has been more than offset by lower gas
commodity prices. In addition, NW Natural has been able to offset firm
transportation charges, in part, by making off-system sales and releasing
capacity in periods when core market customers do not fully utilize firm
pipeline capacity.

         NW Natural supplies many of its non-core customers (larger industrial
interruptible customers with full or partial dual fuel capabilities) through gas
transportation service, delivering gas purchased by these customers directly
from suppliers. (See "Transportation".)

- -------------------------
     (1) One therm is equivalent to 100 cubic feet of natural gas at an assumed
heat content of 1,000 British Thermal Units (Btu's) per cubic foot.

Gas Supply -- Core Market Basic Supply
- --------------------------------------

         NW Natural purchases gas for its core market from a variety of
suppliers located in the western United States and Canada. At January 1, 1998,
NW Natural had 21 firm contracts with 20 suppliers with original terms of from
four months to 15 years which provided for a maximum of 2,757,090 therms of firm
gas per day during the peak winter season and 1,418,300 therms per day during
the remainder of the year. About 80 percent of the annual supply comes from
Canada.

         The terms of NW Natural's principal purchase agreements are summarized
as follows:

         An agreement expiring November 1, 2003, with CanWest Gas Supply, Inc.
(CanWest), an aggregator for gas producers in British Columbia, Canada, entitles
NW Natural to purchase up to 960,000 therms of firm gas per day. This agreement
contains a demand and commodity pricing structure and a provision for annual
renegotiations of the commodity price to reflect then-prevailing market prices.
The demand charges reflect the reservation of firm transportation space on the
Westcoast Energy, Inc. pipeline system in British Columbia. These demand charges
are subject to change as approved by the Canadian National Energy Board (NEB) in
rate proceedings similar to those conducted in the United States by the FERC.
This contract contains minimum purchase obligations.

         An agreement also expiring November 1, 2003, with Amoco Canada
Petroleum Company, Ltd., on terms similar to the CanWest agreement, entitles NW
Natural to purchase up to 83,300 therms of firm gas per day. This gas is
aggregated from production in the Canadian province of Alberta and the Yukon and
Northwest Territories. This contract contains minimum purchase obligations.

         An agreement with Poco Petroleums, Ltd., a Canadian producer, expiring
September 30, 2003, entitles NW Natural to purchase up to 155,160 therms per day
during the winter and up to 110,000 therms per day during the summer of gas
produced in Alberta.

         Two agreements expiring September 30, 2003 with Westcoast Gas Services
entitle NW Natural to purchase up to 140,000 therms per day year-round, plus up
to 92,750 therms per day as winter season supply, of gas produced in Alberta.
Pricing for supplies under these agreements can be renegotiated annually. The
current pricing arrangement includes demand charges for upstream capacity on the
Canadian pipeline systems and a monthly reservation charge. The commodity
pricing consists of a portion of the daily contract quantity at a fixed price
and the remaining daily contract quantity tied to a monthly Canadian index.

         An agreement expiring October 31, 2000, with Summit Resources Ltd.,
entitles NW Natural to purchase up to 77,580 therms per day during the winter
and up to 50,000 therms per day during the summer of gas produced in Alberta.
Pricing for supplies under this agreement can be renegotiated annually. The
current pricing arrangement includes demand charges for upstream capacity on
NOVA Corporation of Alberta's system and commodity charges that are fixed in
three volumetrically based tiers.

         During 1997, new short-term (4 or 5 month) purchase agreements for firm
gas were entered into with 14 suppliers which provide for a total of 1,181,130
therms per day during the 1997-98 heating season. These contracts have a variety
of pricing structures and purchase obligations. NW Natural intends to enter into
new short-term purchase agreements in 1998 for equivalent volumes of gas with
these or other similar suppliers to be available during the 1998-99 winter
season.

         NW Natural continues to purchase gas under agreements with two
producers (one of which is Financial Corporation), for gas produced from the
Mist gas field, located about 60 miles northwest of Portland, Oregon. The
production areas are situated near NW Natural's existing underground gas storage
facility. These agreements have primary terms of 10 years and prices that are
tied to NW Natural's weighted average cost of gas. Current production is
approximately 25,000 therms per day from about 17 wells, supplying about 1
percent of NW Natural's total annual requirements. Production from these wells
varies as existing wells are depleted and new wells are drilled.

         During 1997, approximately 23 percent of NW Natural's purchases for its
core market was from the spot market (30 days or less), a significant increase
from the prior year. This reflects the increased flexibility provided under the
terms of NW Natural's firm supply contracts which permit the purchase of spot
gas under certain conditions and allowed NW Natural to take advantage of
generally depressed spot market prices in the western United States and Canada.

         NW Natural's goal in purchasing gas for its core market is to meet
customers' needs at reasonable prices. NW Natural believes that gas supplies
available from suppliers in the western United States and Canada are adequate to
serve its core market customers for the foreseeable future, and that the cost of
such gas generally will track market prices.

Gas Supply -- Core Market Peaking Supply
- ----------------------------------------

         NW Natural supplements its firm gas supplies with gas from
Company-owned or contracted peaking facilities in which gas is stored during
periods of low demand for use during periods of peak demand. In addition to
enabling NW Natural to meet its peak demand, these facilities make it possible
to lower the annual average cost of gas by allowing NW Natural both to reduce
its pipeline transportation contract demand and to purchase gas for storage
during the summer months when prices are generally at their lowest.

         NW Natural has contracts with NPC which expire in 2004 for firm storage
services from the underground gas storage field at Jackson Prairie near
Centralia, Washington, and the liquefied natural gas (LNG) facility at Plymouth,
Washington. Together, these facilities provide NW Natural with daily firm
deliverability of 923,470 therms and total seasonal capacity of 13,082,647
therms. In addition, NW Natural has a contract with NPC which continues from
year-to-year, at NW Natural's sole option, for additional daily deliverability
of 132,510 therms and additional seasonal capacity of 2,779,970 therms from the
Jackson Prairie storage field. Separate contracts with NPC provide for the
transportation of these storage supplies to NW Natural's service territory.

         NW Natural owns and operates two LNG plants which liquefy gas during
the summer months for use during the peak winter season. These two plants, one
located in Portland and the other near Newport, Oregon, provide a maximum daily
deliverability of 1.8 million therms and a total seasonal capacity of 17 million
therms. NW Natural also owns and operates an underground gas storage facility at
Mist, Oregon. This facility has a maximum daily deliverability of 1 million
therms and a total seasonal working gas capacity of 70 million therms. NW
Natural is engaged in a multi-year, major expansion of the Mist storage
facility.

         NW Natural has a contract with Portland General Electric Company (PGE)
which expires in 2010 that provides NW Natural with additional winter peaking
supply. With certain limitations, NW Natural may interrupt gas deliveries to
PGE, use that gas for its core customers, and compensate PGE for its cost of
replacement fuel oil. The daily deliverability under this contract is 300,000
therms.

         NW Natural also has contracts with two industrial customers, one gas
marketing company and another local gas distribution company on terms similar to
those under the contract with PGE which provide a total of 137,000 therms per
day of year-round capacity, plus 150,000 therms per day of recallable capacity
and supply. These contracts have original terms ranging from five to ten years.

Gas Supply -- Transportation
- ----------------------------

         Between 1988 and early 1992, most of NW Natural's large industrial
interruptible customers switched from sales service to transportation service,
whereby they purchased gas directly from suppliers and shipped the gas on the
Company's system and those of its pipeline suppliers for a fee. Since 1992, many
of these customers have returned to sales service, primarily because NW
Natural's industrial sales rates were lower than those customers' costs of
purchasing and shipping their own gas. The ability of industrial customers to
switch between sales service and transportation service has made it possible for
NW Natural to retain most of these customers. Because transportation charges
typically have been the same as the margin on an equivalent sale of gas,
switching between sales service and transportation service by industrial
interruptible customers has not had a material effect on NW Natural's results of
operations. (See "Competition and Marketing".)

Regulation and Rates
- --------------------

         NW Natural is subject to regulation with respect to, among other
matters, rates, systems of accounts and issuance of securities by the OPUC and
the WUTC. In 1997, 94 percent of both NW Natural's gas deliveries and its
utility operating revenues were derived from Oregon customers and the balance
from Washington customers. The Company is exempt from the provisions of the
Natural Gas Act by order of the Federal Power Commission (now the FERC).

         NW Natural's most recent general rate case in Oregon, which was
effective in 1989, authorized rates designed to produce a return on common
equity of 13.25 percent. The most recent general rate increase in Washington,
which was effective in 1997, authorized rates designed to produce a return on
common equity of 11.25 percent. Actual revenues resulting from the OPUC's and
WUTC's general rate orders are dependent on weather, economic conditions,
customer growth, competition and other factors affecting gas usage in NW
Natural's service area. NW Natural's returns on average common equity from
utility operations were 13.7 percent in 1996 and 12.0 percent in 1997. The
Company's returns from consolidated operations, including subsidiary results,
were 13.0 percent in 1996 and 11.3 percent in 1997.

         NW Natural tentatively plans to file for a general rate increase in
Oregon in the fourth quarter of 1998.

         In Oregon, NW Natural has a Purchased Gas Cost Adjustment (PGA) tariff
under which net income derived from Oregon operations is affected only within
defined limits by changes in purchased gas costs. The PGA tariff provides for
periodic revisions in rates due to changes in the Company's cost of purchased
gas. Costs included in the PGA adjustments are based on NW Natural's gas
requirements for the 12-month period ended each June 30. Any resulting rate
adjustments, derived from gas prices negotiated for the gas supply contract year
commencing on the following November 1, are made effective on the following
December 1.

         Effective January 1, 1998, the PGA tariff provides that 67 percent of
any difference between actual purchased gas costs and estimated purchased gas
costs incorporated into rates will be deferred for amortization in subsequent
periods. If actual gas commodity costs exceed those incorporated in rates, NW
Natural subsequently will adjust its rates upward to recover 67 percent of the
deficiency from core market customers. Similarly, if actual gas commodity costs
are lower than those reflected in rates, rates will be adjusted downward to
distribute to core market customers 67 percent of such gas commodity cost
savings.

         In Washington, NW Natural is permitted to track increases and decreases
in gas commodity costs coincidental with their incurrence, with the result that
net income is not directly affected by changes in gas commodity costs.

         In both Oregon and Washington, the PGA permits NW Natural to recover
100 percent of FERC-approved pipeline transportation cost increases.

         In October 1997, NW Natural filed under its Oregon PGA tariff to
increase rates for Oregon customers by an average of 11.4 percent. The OPUC
approved the filing effective January 1, 1998, along with a settlement between
NW Natural and the OPUC Staff. The settlement modified the incentive formula for
future deferrals of variations in gas costs, from 80 percent to 67 percent, and
provided for a revenue reduction not relating to gas costs amounting to $2.5
million per year, effective on a deferred basis as of January 1, 1998. In
February 1998, NW Natural filed a further rate increase averaging 6.1 percent
under the PGA tariff, proposing as of April 1, 1998, to remove a temporary rate
discount in effect since December 1996.

         In October 1997, NW Natural filed under its Washington PGA tariff to
increase rates for Washington customers by 11.4 percent. The WUTC approved a
substitute filing increasing rates by 10.5 percent effective December 1, 1997.

         The OPUC and WUTC have approved transportation tariffs under which NW
Natural may contract with customers to deliver customer-owned gas. Under these
tariffs, revenues from the transportation of customer-owned gas, except that of
large industrial customers having the capability of bypassing NW Natural's
system, generally are equivalent to the margins that would have been realized
from sales of Company-owned gas. (See "Gas Supply -- Transportation" and
"Competition and Marketing".)

         The OPUC and WUTC have implemented "integrated resource planning"
processes under which utilities develop plans defining alternative growth
scenarios and resource acquisition strategies. In 1996, the OPUC acknowledged
and accepted NW Natural's submission of its third Integrated Resource Plan. The
WUTC acknowledged and accepted NW Natural's third plan in 1997. Elements of the
Plan included an evaluation of supply and demand resources; the consideration of
uncertainties in the planning process and the need for flexibility to respond to
changes; a primary goal of "least cost" service; and consistency with state
energy policy. Although the OPUC's order acknowledging the Integrated Resource
Plan does not constitute ratemaking approval of any specific resource
acquisition or expenditure, the OPUC indicated that it would give considerable
weight in prudency reviews to utility actions that are consistent with
acknowledged plans. NW Natural will file its fourth Integrated Resource Plan for
acknowledgment by the OPUC and WUTC in 1998.

Competition and Marketing
- -------------------------

         NW Natural has no direct competition in its service area from other
natural gas distributors. For residential customers' heating needs, however, NW
Natural competes with electricity, fuel oil, and, to a lesser extent, wood. It
also competes with electricity and fuel oil for commercial applications.
Competition among these forms of energy is based on price, reliability,
efficiency and performance. In 1997, NW Natural maintained its competitive price
advantage over electricity and approximate price parity with fuel oil in both
the residential and commercial markets. Throughout 1997, natural gas rates
continued to be substantially lower than rates for electricity provided by the
investor-owned utilities which serve approximately 75 percent of the homes in NW
Natural's Oregon service area. NW Natural believes that this rate advantage will
continue for the foreseeable future.

         The relatively low saturation of natural gas in residential
single-family and attached dwellings in NW Natural's service territory,
estimated at between 33 and 40 percent, together with the price advantage of
natural gas compared with electricity and its operating convenience over fuel
oil, provides the potential for continuing growth in the residential conversion
market. In 1997, 21,848 net residential customers (after subtracting
disconnected or terminated services) were added, including 8,718 units of
existing residential housing which were reconnected to the system or were
converted from oil or electric appliances to natural gas. Of the new heating
conversions from other fuels, at least 60 percent converted to gas for water
heating. In addition, 3,006 net commercial customers were connected in 1997. The
net total of all new customers added in 1997, including industrial sales and
transportation customers, was 24,852. This constituted a growth rate of 5.7
percent, more than three times the national average for local distribution
companies as reported by the American Gas Association.

         Despite warmer weather, natural gas sales volumes to residential and
commercial customers in 1997 were about the same as in 1996, largely due to new
customer acquisitions. For the year 1997, temperatures in NW Natural's service
territory, based on heating degree days, were 8 percent warmer than in 1996 and
4 percent warmer than the 20-year average.

         The Pacific Northwest has historically enjoyed some of the lowest
electric rates in the nation, primarily due to the proximity of federal
hydropower facilities. With further deregulation in the energy business, the
region is unlikely to experience the large drop in electric rates expected in
other, high-cost areas of the country.

         While the natural gas industry, including producers, interstate
pipelines and local distribution companies (LDCs), has undergone many changes in
its long history, perhaps no era has brought greater change than the past 10
years. These changes, brought about by the deregulation or restructuring of the
energy markets, are intended to promote competition where it is economically
beneficial to consumers. The changes are continuing, though at different rates
among the various regulatory jurisdictions around the country.

         Traditionally, LDCs have sold a "bundled" product which included the
natural gas itself as well as delivery to the meter. Since the late 1980s,
however, large customers have sought savings by procuring their own supplies of
natural gas from producers and contracting with pipelines and LDCs for
transportation. Since the cost of the gas commodity is passed through directly
to LDC customers without markup, the impact to net income when a customer
chooses transportation service has been negligible. While NW Natural's ability
to obtain competitively-priced gas commodity has enabled it to retain sales
customers, further deregulation of the industry may bring an unbundled product
offering to a greater number of customers, such that an increasing number of
suppliers will actively compete for customers' gas commodity business. However,
since the final delivery of customer-owned gas will continue to be through
regulated distribution systems, no material impact to NW Natural's profitability
is anticipated. Bypass of NW Natural's facilities by other potential providers
of delivery service is not considered a widespread, significant threat because
of the nature of NW Natural's customer base and proximity to interstate
pipelines.

         Total industrial throughput, including both sales and transportation of
firm and interruptible gas, was 579 million therms in 1997, up 2.7 percent from
564 million therms in 1996. This growth in industrial throughput is an indicator
of the economic health of the region served by NW Natural. The basic industries
such as forest products and metals continue to consolidate and experience only
slow growth. But a new manufacturing base, notably high-technology, is emerging
and has expanded and diversified the region's economic base. This economic
growth has contributed to an increase in industrial gas volumes averaging 2
percent per year over the past four years.

         Industrial firm gas sales and transportation deliveries during 1997
totaled 194 million therms, up 41 percent from 1996. This increase reflects
mid-year transfers of several large customers previously served under
interruptible rates (52 million therms) and the effects of a strong local
economy. In 1997, 9 percent of total utility operating revenues and 17 percent
of total therms delivered were derived from sales and transportation deliveries
to industrial firm customers.

         Industrial interruptible gas sales and transportation deliveries during
1997 totaled 385 million therms, down 10 percent from 1996. While economic
expansion strengthened interruptible deliveries, a number of larger customers
migrated from tariff-based interruptible transportation or sales rates to
individually negotiated transportation agreements based upon bypass economics
(the customers' costs of a direct connection to an interstate pipeline). In
1997, 9 percent of total utility operating revenues and 35 percent of total
therms delivered were derived from sales and transportation deliveries to
industrial interruptible customers.

         As described above, NW Natural and many of its largest industrial
customers have entered into negotiated transportation service agreements. These
agreements are designed to provide rates that are either: 1) competitive with
the costs of alternative fuels, such as heavy oil, or 2) competitive with the
customer's bypass alternatives. These agreements generally prohibit bypass
during their terms. NW Natural currently has a proposed contract before the OPUC
which, if not approved, may expose NW Natural to a bypass risk of up to 6
million therms of deliveries per year to a single customer. Other than this
possibility, NW Natural does not expect significant bypass to occur in the
foreseeable future.

         Since 1994, NW Natural has been authorized by the OPUC to make
off-system commodity sales and to release portions of its firm interstate
pipeline capacity at discounted rates when seasonal demand is low. This
authorization allows NW Natural to compete effectively with independent gas
marketers. Eighty percent of all positive net revenues (gross revenues less the
actual cost of gas or pipeline capacity) generated from these sales and capacity
releases ($3.5 million in 1997) have been credited to Oregon core market
customer gas costs. Effective March 2, 1998, the crediting factor for off-system
commodity sales changed from 80 percent to 67 percent.

         During 1997, NW Natural entered into a marketing alliance with
PacifiCorp, the purpose of which is to provide electric and gas commodity
services to industrial and commercial customers in the states of Oregon and
Washington. In addition, the alliance will provide other energy-related services
and products. NW Natural does not expect the alliance to have a material impact
on its earnings. The primary value of the alliance is to provide convenience and
extra value to end-use customers, creating a more loyal customer base for both
NW Natural and PacifiCorp. PacifiCorp provides wholesale power throughout the
U.S. and electricity and energy-related services to over 1.4 million retail
customers in seven western states through its divisions, Pacific Power and Utah
Power.

Environment
- -----------

         NW Natural is subject to air, water, hazardous waste and other
environmental regulation by state and federal authorities and has complied in
all material respects with applicable regulations. Compliance with these
regulations has not had a material effect on the Company's capital expenditures,
earnings or competitive position.

         NW Natural owns property in Linnton, Oregon and previously owned
property in Salem and Eugene, Oregon that were sites of former gas manufacturing
plants. The Linnton site is currently under investigation for potential
remediation. The Company received a release from further liability for the Salem
property in 1996. (See Part II, Item 7., "Environmental Matters.")

Employees
- ---------

         At year-end 1997, NW Natural had 1,337 employees, of which 900 were
members of the Office and Professional Employees International Union, Local No.
11. These union employees are working under a seven-year Joint Accord covering
wages, benefits and working conditions which will expire March 31, 2004.

ITEM 2.  PROPERTIES

         NW Natural's natural gas distribution system consists of approximately
10,500 miles of mains, as well as service pipes, meters and regulators, and gas
regulating and metering stations. The mains and feeder lines are located in
municipal streets or alleys pursuant to valid franchise or occupation
ordinances, in county roads or state highways pursuant to valid agreements or
permits granted pursuant to statute, or on lands of others pursuant to valid
easements obtained from the owners of such lands. NW Natural also holds all
necessary permits for the crossing of the Willamette River and a number of
smaller rivers by its mains.

         NW Natural owns service facilities in Portland, as well as various
satellite service centers, garages, warehouses, and other buildings necessary
and useful in the conduct of its business. It leases office space in Portland
for its corporate headquarters. District offices are maintained on owned or
leased premises at convenient points in the distribution system. NW Natural owns
LNG facilities in Portland and near Newport, Oregon, and also owns two
underground natural gas reservoirs at Mist, Oregon.

         NW Natural considers all of its properties currently used in its
operations, both owned and leased, to be well maintained, in good operating
condition, and adequate for its present and foreseeable future needs.

         NW Natural 's Mortgage and Deed of Trust constitutes a first mortgage
lien on substantially all of the real property constituting its utility plant.

         NW Natural holds interests in 8,915 net acres of underground natural
gas storage in Oregon. Financial Corporation holds interests in United States
oil and gas leases covering 8,558 net acres located in Oregon, California,
Wyoming, and Colorado. Canor holds interests in Canadian gas and oil leases
covering 149,211 net acres in Alberta and Saskatchewan. Most Canadian gas
production is sold under long-term contracts to markets in both Canada and the
United States. NW Natural owns four depleted gas reservoirs near Mist, Oregon,
that will be developed as underground gas storage facilities. It also holds an
option to purchase future storage rights in certain other areas of the Mist gas
field. The Company also holds an equity investment in a Boeing 737-300 aircraft.

ITEM 3.  LEGAL PROCEEDINGS

         In July 1995, a jury in an Oregon state court returned a verdict
against NW Natural in the case of Northwest Natural Gas Company v. Chase
                                  --------------------------------------
Gardens, Inc. (Lane County Circuit Court Case No. 16-91-01370). The Oregon
- -------------
Court of Appeals (Oregon Court of Appeals Case No. CA A90481) affirmed the trial
court decision in February 1997. The Oregon Supreme Court agreed to hear the
case on appeal and is expected to render a final ruling during 1998. NW Natural
recorded a charge of $5.6 million in the fourth quarter of 1996, equivalent to
15 cents a share, as a reserve against payment of the judgment, costs and
post-judgment interest from the case.

         The Company is party to certain other legal proceedings in which
claimants seek material amounts. Although it is not possible to predict the
outcome with certainty, based upon the opinions of legal counsel, management
does not expect disposition of these matters to have a materially adverse effect
on the Company's financial position, results of operations or cash flows.

ITEM 4.  SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS

         There were no matters submitted to a vote of security holders, through
the solicitation of proxies or otherwise, during the fourth quarter of the year
ended December 31, 1997.

ITEM 5.   MARKET FOR THE REGISTRANT'S COMMON EQUITY AND RELATED STOCKHOLDER

          MATTERS

         (A) NW Natural's common stock is traded on the Nasdaq National Market
tier of the Nasdaq Stock Market, which reports the daily high, low and closing
transaction prices, as well as volume data, under the symbol "NWNG".

         NW Natural's common stock is included on the Federal Reserve Board's
list of over-the-counter securities determined to be subject to margin
requirements under the Board's regulations.

       NW Natural's common stock was split three-for-two effective September 6,
1996, in the form of a 50% stock dividend, to shareholders of record August 23,
1996. Share prices and dividends paid on shares of NW Natural's common stock for
periods prior to the effective date of the stock split, have been adjusted for
the stock split.

         The quarterly high and low closing trades for NW Natural's common
stock, as quoted on the Nasdaq National Market and published in the Wall Street
Journal and on Nasdaq's World Wide Web site, were as follows:

                         1997                   1996
                  ------------------    -------------------

December 31 .....  31.25       24.38      25.75       23.25

         The closing quotation for the common stock on December 31, 1997 was
$31.00. On December 31, 1996 the closing quotation was $24.00.

         (B) As of December 31, 1997 there were 10,097 holders of record of the
Company's common stock.

         (C) NW Natural has paid quarterly dividends on its common stock in each
year since the stock first was issued to the public in 1951. Annual common
dividend payments have increased each year since 1956. Dividends per share paid
during the past two years were as follows:

          Payment Date:                       1997                     1996

                                              ------                   -----
               Total per share                $1.205                   $1.20

         It is the intention of the Board of Directors to continue to pay cash
dividends on the Company's common stock on a quarterly basis. However, future
dividends will be dependent upon NW Natural's earnings, its financial condition
and other factors.

         NW Natural's Dividend Reinvestment and Stock Purchase Plan permits
registered owners of common stock to reinvest all or a portion of their
quarterly dividends in additional shares of NW Natural's common stock at the
current market price. Shareholders also may invest cash on a monthly basis, up
to $50,000 per calendar year, in additional shares at the current market price.
During 1997, dividend reinvestments and optional cash investments under the Plan
aggregated $5.2 million and resulted in the issuance of 211,532 shares of common
stock. During the 20 years the Plan has been available the Company has issued
and sold 3,400,110 shares of common stock which produced $70.1 million in
additional capital.

ITEM 7.   MANAGEMENT'S  DISCUSSION AND ANALYSIS OF RESULTS OF OPERATIONS AND
          FINANCIAL CONDITION

          The consolidated financial statements include:
          Regulated utility:

               Northwest Natural Gas Company (NW Natural)
          Non-regulated wholly-owned subsidiaries:

               NNG Financial Corporation (Financial Corporation)
               Canor Energy, Ltd. (Canor)
               Oregon Natural Gas Development Corporation (Oregon
               Natural)-merged with and into NW Natural during the
               second quarter of 1996

          Together these businesses are referred to herein as the "Company" (see
"Subsidiary Operations" below and Note 2 to the Consolidated Financial
Statements).

          The following is management's assessment of the Company's financial
condition including the principal factors that affect results of operations. The
discussion refers to the consolidated activities of the Company for the three
years ended December 31, 1997.

Earnings and Dividends
- ----------------------

          In 1997, the Company's earnings applicable to common stock were $40.4
million, the second highest in the Company's history. Earnings in 1996 were a
record $44.1 million, up 25 percent from $35.3 million in 1995. The higher 1996
earnings reflect both colder weather and customer growth. Earnings for both 1997
and 1995 were lower due to warmer than normal weather, the effect of which was
partially offset by additional sales from customer growth.

          The Company's basic earnings from consolidated operations were $1.78 a
share in 1997, down from $1.97 a share in 1996 and up from $1.62 a share in
1995.

          NW Natural earned $1.70 a share from gas utility operations in 1997,
compared to $1.87 in 1996 and $1.43 in 1995. Weather conditions in NW Natural's
service territory in 1997 were 8 percent warmer than in 1996 and 4 percent
warmer than the 20-year average. Weather in 1996 was 17 percent colder than 1995
and 4 percent colder than the 20-year average. The estimated weather-related
decrease in net operating revenues (margin) during 1997 was equivalent to about
24 cents a share compared to actual conditions during 1996. The colder weather
in 1996 resulted in increased gas deliveries to, and related margin from,
weather-sensitive customers. The weather-related increase in 1996 was equivalent
to about 55 cents a share compared to actual conditions in 1995.

          Customer growth of 5.7 percent during both 1997 and 1996 contributed
an estimated $12.6 million to 1997 margin and $10.9 million to 1996 margin.
Customer growth of 4.7 percent during 1995 contributed an estimated $9.7 million
to margin.

          The estimated impact on margin of weather and customer growth are
derived from NW Natural's internal planning model. The model calculates expected
sales to, and revenues from, residential and commercial customers for "base
usage," representing gas use for water heaters, ranges, and other appliances not
sensitive to outside temperatures. The model also calculates expected sales to,
and revenues from, these customers for "heat sensitive" usage, primarily
furnaces, as a function of heating degree days (the difference between 65
degrees Fahrenheit and the average of a day's high and low temperatures). The
model then estimates the earnings effect of the difference between expected
sales and revenues under actual temperature conditions, and expected sales and
revenues under average temperature conditions.

          Subsidiary earnings for 1997 were equivalent to 8 cents a share,
compared to 10 cents in 1996 and 19 cents in 1995. The decrease in 1997 from
1996 was primarily due to a one-time $2.9 million gain in 1996 from Oregon
Natural's sale of its underground storage assets to NW Natural which was offset
in part by an impairment loss of $1.3 million on producing wells and a $1.0
million write-down of unproven properties. The decrease in 1996 from 1995 was
primarily due to a one-time $3.8 million gain in 1995 from Oregon Natural's sale
of production and related gathering system assets.

          1997 was the 42nd consecutive year in which the Company's dividends
paid have increased. Dividends paid on common stock were $1.205 a share in 1997
compared with $1.20 in 1996 and $1.18 in 1995.

Results of Operations
- ---------------------
     Regulatory Matters
     ------------------

          NW Natural provides gas utility service in Oregon and Washington, with
Oregon representing approximately 94 percent of its revenues. Future earnings
and cash flows from utility operations will be determined for the most part by
continued growth in the residential and commercial markets, and by NW Natural's
ability to remain price competitive in the large industrial market, to control
expenses, and to obtain timely regulatory approval for rate changes reflecting
investments in new utility plant.

          NW Natural currently has no competition from other gas utility
distributors in the territory it serves. However, it competes with Northwest
Pipeline Corporation (NPC) to serve large industrial customers, with oil and
electricity for industrial and commercial uses, and with oil, electricity, and
wood for residential use. The Pacific Northwest has historically enjoyed some of
the lowest electric rates in the nation, primarily due to the proximity of
federal hydropower facilities. With further deregulation of the energy business,
the market for energy will become more competitive, but the Pacific Northwest is
unlikely to experience the large drop in electric rates that other, high-cost
areas of the country are anticipating. In 1997, NW Natural maintained its
competitive advantage over electricity and approximate price parity with fuel
oil in the residential and commercial markets.

          In October 1997, the Washington Utilities and Transportation
Commission (WUTC) approved a general rate increase averaging 3 percent for NW
Natural's customers in Washington. Revenue from Washington operations will
increase by approximately $0.6 million annually due to the combined effects of
the general rate increase of about $0.5 million and a temporary surcharge to
recover over five years the balance of deferred expense related to retiree
health care and life insurance benefits attributable to Washington operations.
The WUTC authorized a return on common equity of 11.25 percent. Effective
December 1, 1997, the WUTC approved a rate increase averaging 10.5 percent to
pass through to Washington customers increases in purchased gas costs and to
remove temporary rate increments to amortize balances in deferred accounts. The
WUTC approved rate decreases averaging 4.9 percent and 8.0 percent,
respectively, effective December 1, 1996 and 1995.

          Effective January 1, 1998, the Oregon Public Utility Commission (OPUC)
approved rate increases averaging 11.4 percent for NW Natural's customers in
Oregon. The OPUC also approved a settlement modifying the incentive formula for
deferrals of variations in gas costs, from 80 percent to 67 percent. The OPUC
approved rate decreases averaging 3.6 percent and 6.7 percent effective December
1, 1996 and 1995, respectively. The rate increases in Oregon in 1998 and the
rate decreases in 1996 and 1995 reflected changes in NW Natural's purchased gas
costs, the application of temporary rate adjustments to amortize regulatory
balancing accounts and the removal of temporary rate adjustments effective the
previous year.

          None of the rate increases and decreases discussed above had a
material effect on net income.

</TABLE>

          Residential and Commercial
          --------------------------

          NW Natural continues to experience a rapid customer growth rate
relative to others in the industry. The 24,852 customers added during 1997
represent a growth rate of 5.7 percent, repeating the record growth rate
achieved in 1996. In the three years ended December 31, 1997, more than 66,000
customers were added to the system, representing an average annual growth rate
of 5.4 percent.

          Weather conditions were 4 percent warmer than average in 1997, 4
percent colder than average in 1996, and 12 percent warmer than average in 1995.
Average weather conditions are calculated from the most recent 20 years of
temperature data measured by heating degree days. Weather in 1997 was 8 percent
warmer than in 1996 while 1996 was 17 percent colder than 1995.

          Typically, 75 percent or more of NW Natural's annual operating
revenues are derived from gas sales to weather-sensitive residential and
commercial customers. Accordingly, variations in temperatures between periods
will affect volumes of gas sold to, and revenues derived from, these customers.

          The volumes of gas sold to residential and commercial customers during
1997 were comparable to 1996, reflecting the combined effects of residential and
commercial volumes added from customer growth, offset by reduced gas use due to
warmer weather. Related revenues decreased 3 percent primarily due to rate
decreases effective December 1, 1996. The addition of 23,220 customers and 17
percent colder weather in 1996 compared to 1995 resulted in a 9 percent increase
in related revenues over 1995.

          In order to match revenues with related purchased gas costs, NW
Natural records unbilled revenues for gas delivered but not yet billed to
customers through the end of the period.

          Industrial Sales, Transportation and Other Revenues
          ---------------------------------------------------

          The combined margin from industrial sales and transportation decreased
5 percent in 1997, from $53.9 million in 1996 to $51.3 million in 1997, and
increased 9 percent from $49.6 million in 1995 to $53.9 million in 1996. Total
volumes delivered to industrial customers were 15.3 million therms, or 3
percent, higher in 1997 than in 1996. The decrease in margin despite increased
volumes in 1997 reflects the migration by some customers to lower rates under
special anti-bypass contracts. Total volumes delivered to industrial customers
were 16.7 million therms, or 3 percent, higher in 1996 than in 1995. In addition
to higher volumes, margin improved in 1996 due to higher prices under industrial
incentive rate schedules which are designed to track changes in oil prices.

          NW Natural did not experience margin losses from new bypasses of its
system in 1997, 1996 or 1995. Although NW Natural does not expect a significant
number of its large customers to bypass its system in the foreseeable future, it
may experience further deterioration of margin associated with customers'
transfers to contracts with pricing designed to be competitive with the capital
and operating costs of direct connections to NPC's system.

          Other revenues primarily relate to adjustments in regulatory accounts
(see Note 1 to the Consolidated Financial Statements). Other revenues for 1997
included $6.1 million from the amortization of property tax savings and $1.2
million from the amortization of Oregon income tax savings.

          In 1996, other revenues included $4.0 million from the amortization of
property tax savings, $1.6 million from regulatory amortizations, and two
non-recurring gains. Specifically, NW Natural recorded a gain of $0.7 million
for the recovery of costs and lost revenues related to energy conservation
programs approved by the OPUC. NW Natural also recorded a gain of $0.9 million
as the result of a settlement with the OPUC concerning amounts to be refunded to
Oregon customers from prior-year savings in property taxes and Oregon income
taxes.

          In 1995, other revenues included a one-time, $3.0 million payment
under a contract with Portland General Electric Company (PGE), an electric
utility based in Portland. This contract gave PGE the option to request gas
transportation service for electric generation at one or more sites in NW
Natural's service territory. Additionally, other revenues in 1995 included $2.3
million from amortization of the Interruptible Sales Adjustment account and $3.1
million from other regulatory amortizations.

          Cost of Gas
          -----------

          The cost per therm of gas sold during 1997 was 7 percent lower than in
1996, while such cost in 1996 was 10 percent lower than in 1995. The cost per
therm of gas sold includes current gas purchases, gas drawn from storage, demand
cost equalization, regulatory deferrals, and company use. For the years 1997,
1996 and 1995, the cost of gas sold was reduced by non-regulated gas sales of
$2.3 million, $1.2 million, and $0.3 million, respectively. Under an agreement
with the OPUC, these sales are treated as a reduction of gas costs.

          The average cost per therm of gas purchased was 8 percent higher in
1997 than in 1996, due to fluctuations in prices NW Natural paid for the portion
of its gas supplies tied to monthly market price indexes. NW Natural has a
Purchased Gas Cost Adjustment (PGA) tariff under which its net income from
Oregon operations is affected only within defined limits by changes in purchased
gas costs. In 1997, NW Natural absorbed 20 percent of the higher cost of gas
purchased, as compared to projections, under its Oregon PGA tariff. The
remaining 80 percent of the higher gas costs was recorded as deferred debits
(regulatory assets). Effective January 1, 1998, the incentive formula for
deferred gas costs was modified so that NW Natural will absorb 33 percent of the
difference between actual and projected gas costs and the remaining 67 percent
will be deferred for recovery or refund to customers in future rates.

          Subsidiary Operations
          ---------------------

          Consolidated subsidiary earnings for 1997 were $1.8 million,
equivalent to 8 cents a share, compared to $2.2 million, or 10 cents a share, in
1996, and $4.1 million, or 19 cents a share, in 1995 (see Note 2 to the
Consolidated Financial Statements).

          In 1997, Financial Corporation earned $1.6 million, compared to $1.0
million in 1996 and $1.3 million in 1995. 1997 results included a $1.1 million
gain from the sale of Financial Corporation's interest in a California solar
electric generation partnership during the fourth quarter. The decreases in
Financial Corporation's on-going operating results from 1996 to 1997 and from
1995 to 1996 were primarily due to weaker operating results attributable to its
investments in windpower energy facilities in California.

          Canor earned $0.2 million in 1997, compared to $0.5 million in 1996.
Canor's 1997 results included a $0.9 million write-down of unproven properties
in the fourth quarter, while 1996 results include $0.9 million in impairment
losses resulting from the application of Statement of Financial Accounting
Standards (SFAS) No. 121, "Accounting for the Impairment of Long-Lived Assets
and for Long-Lived Assets to Be Disposed Of." Oregon Natural was merged into NW
Natural during 1996, thereby effecting the transfer of certain assets, including
the stock of Canor, to NW Natural. As a result of this merger, Canor became a
wholly-owned subsidiary of NW Natural. Earnings from Canor's operations in 1995,
prior to the merger, are included in Oregon Natural's results of operations.

          Oregon Natural earned $0.7 million in 1996 compared to $1.8 million in
1995. Oregon Natural's earnings in 1996 and 1995 included one-time gains from
asset sales, including a $2.9 million gain from the sale of underground storage
assets to NW Natural in 1996, and a $3.8 million gain from the sale of its
gathering system and gas producing properties in 1995. The 1996 gain was
partially offset by a $1.3 million impairment loss on producing wells and a $1.0
million write-down of unproven properties.

     Operating Expenses
     ------------------

          Operations and Maintenance
          --------------------------

          Consolidated operations and maintenance expenses were $2.3 million, or
3 percent, lower in 1997 than in 1996. NW Natural's operations and maintenance
expenses in 1997 decreased $2.1 million, or 3 percent, compared to 1996
primarily due to a one-time charge of $4.9 million in 1996 for 1995 litigation
(see "Chase Gardens Litigation", below), offset by increases in customer service
and market development expense ($2.9 million); electronic and network services
($0.6 million); and environmental investigation and remediation charges ($0.6
million). Included in 1997 operations and maintenance expense was a $4 million
increase in payroll due to salary increases as well as wage increases resulting
from NW Natural's new seven-year labor agreement effective April 1, 1997.
Subsidiary expenses decreased $0.2 million, or 6 percent, in 1997 compared to
1996 primarily due to a decline in oil and gas production costs.

          NW Natural's operations and maintenance expenses in 1996 were $9.3
million higher than in 1995, while subsidiary expenses decreased $1.1 million.
The increase in utility operations and maintenance expenses was primarily due to
the $4.9 million judgment against NW Natural in the Chase Gardens litigation 
                                                    -------------
(see below); expenses related to cold weather and floods ($0.6 million); higher 
bonus accruals ($1.9 million); environmental investigation costs ($0.4 million);
service costs tied to customer growth ($0.8 million); and market development 
costs ($0.7 million). Lower subsidiary operations and maintenance expenses were 
primarily due to a decline in oil and gas production expenses.

          Chase Gardens Litigation
          ------------------------

          In July 1995, a jury in an Oregon state court returned a verdict
against NW Natural in the case of Northwest Natural Gas Company v. Chase
                                  --------------------------------------
Gardens, Inc. (Lane County Circuit Court Case No. 16-91-01370). The Oregon
- -------------
Court of Appeals (Oregon Court of Appeals Case No. CA A90481) affirmed the trial
court decision in February 1997. The Oregon Supreme Court agreed to hear the
case on appeal and is expected to render a final ruling during 1998. NW Natural
recorded charges of $5.6 million in the fourth quarter of 1996, equivalent to 15
cents a share, as a reserve against payment of the $4.9 million judgment plus
related costs and post-judgment interest.

          Taxes Other Than Income
          -----------------------

          Taxes other than income, which are comprised of property, franchise,
payroll and other taxes, declined $1.6 million, or 8 percent, in 1997. Property
tax expense was $1.6 million, or 17 percent, lower than in 1996, due to
settlements reached in 1996 relating to property valuations and regulatory
treatment of reduced property taxes.

          NW Natural's franchise taxes, which are incurred as a percentage of
revenue, decreased 4 percent, from $8.2 million in 1996 to $7.9 million in 1997,
paralleling the percentage decrease in gas sales revenues from 1996 to 1997. The
decrease in franchise taxes was offset by increased payroll taxes and regulatory
fees.

          Depreciation, Depletion and Amortization
          ----------------------------------------

          Depreciation, depletion and amortization expense increased $1.6
million, or 4 percent, in 1997 compared to 1996, and $2.5 million, or 6 percent,
in 1996 compared to 1995. NW Natural's depreciation expense increased $3.1
million from 1996 to 1997 due to an additional $111.1 million of utility plant
placed in service. The new Customer Information System (CIS), placed in service
in the fourth quarter of 1997, increased depreciation expense by $0.2 million
compared to 1996. NW Natural's depreciation expense decreased $0.7 million, or 2
percent, in 1996 compared to 1995 primarily due to lower depreciation rates
approved by the OPUC and WUTC effective January 1, 1996.

          Depreciation, depletion and amortization expense for subsidiaries
decreased $1.5 million in 1997. Depreciation expense for 1997 included expenses
of $1.7 million recorded by Canor for the write-down of unproven properties and
the abandonment of dry wells. Subsidiary depreciation, depletion and
amortization expense increased $3.2 million, or 79 percent, in 1996 compared to
1995 primarily due to impairment and abandonment expenses totaling $2.3 million
which were recorded by Oregon Natural pursuant to SFAS No. 121 and the
write-down of unproven properties. Canor also recorded a $0.9 million expense
during 1996 pursuant to SFAS No. 121.

          Other Income
          ------------

          The variations in other income during the past three years resulted
primarily from non-recurring items and a $1.4 million decline in interest income
in 1997 from 1996. Oregon Natural recorded a gain in 1996 on the sale of its
underground storage facilities, and recorded a gain in 1995 on the sale of its
gathering system and interests in production assets in Oregon. NNG Energy
Systems, Inc., a wholly-owned subsidiary of the Company that was dissolved in
1995, recorded a gain in 1995 resulting from the reorganization of its
California cogeneration subsidiary.

     Interest Charges
     ----------------

          NW Natural's interest charges increased $2.7 million, or 10 percent,
in 1997 compared to 1996 due to the issuance of $90 million of Medium-Term Notes
during 1997 and higher commercial paper balances outstanding. The average
commercial paper balances increased from $14.0 million in 1996 to $45.8 million
in 1997. The increases in NW Natural's long-term and short-term debt balances
were primarily due to the financing of its $117 million utility construction
program and $28.6 million in deferred gas costs.

          Interest charges in 1996 increased $1.2 million, or 5 percent,
compared to 1995, also due to higher long-term and short-term debt balances
outstanding related to the financing of NW Natural's utility construction
expenditures, and to accrued interest charges of $0.7 million for post-judgment
interest for the Chase Gardens litigation.

          Allowance for Funds Used During Construction (AFUDC) represents the
cost of funds used during the construction of utility plant (see Note 1 to the
Consolidated Financial Statements). In 1997, 1996 and 1995, AFUDC reduced
interest expense by $1.7 million , $0.8 million and $0.6 million, respectively.
The weighted average AFUDC rates were 5.8 percent in 1997, 8.9 percent in 1996
and 5.3 percent in 1995 (See "Financing Activities" below).

     Income Taxes
     ------------

          The effective corporate income tax rate for the years ended December
31, was 33 percent for 1997 and 37 percent for both 1996 and 1995. The lower
1997 tax rate was primarily due to permanent tax savings from the change in book
depreciation rates, an increase in tax credits, and a reversal of amounts
previously recorded for a California solar energy investment that was sold by
Financial Corporation (see Note 7 to the Consolidated Financial Statements).

          The significant increase in 1996 income tax expense was due to the $14
million, or 23 percent, increase in income before income taxes compared to 1995.
In 1996, NW Natural recorded an adjustment reducing tax expense for the year by
$1.9 million, or 8 cents a share, for reversal of deferred tax amounts provided
in prior years.

     Redeemable Preferred and Preference Stock Dividend Requirements
     ---------------------------------------------------------------

          Redeemable preferred and preference stock dividend requirements for
1997 were lower by $0.1 million, or 3 percent, compared to 1996, due to sinking
fund redemptions and the redemption of all the outstanding shares of the $4.68
series of preferred stock in June 1997. 1996 requirements were $0.1 million, or
3 percent, lower than 1995 due to sinking fund redemptions and the conversion or
redemption of the remaining shares of the Convertible Preference Stock, $2.375
Series, in May 1995.

Financial Condition
- -------------------

     Capital Structure
     -----------------

          NW Natural's capital expenditures are incurred primarily for utility
construction resulting from customer growth and system improvements. NW Natural
finances these expenditures from cash provided by operations and from short-term
borrowings which are periodically refinanced through the sale of long-term debt
or equity securities. In addition to its capital expenditures, the
weather-sensitive nature of gas usage by NW Natural's residential and commercial
customers influences the Company's financing requirements. Short-term liquidity
requirements are satisfied primarily through the sale of commercial paper, which
is supported by commercial bank lines of credit (see Note 6 to the Consolidated
Financial Statements).

          The Company's long-term goal is to maintain a capital structure
comprised of 45 to 50 percent common stock equity, 5 to 10 percent preferred and
preference stock and 45 to 50 percent short-term and long-term debt. When
additional capital is required, the Company issues debt or equity securities
depending upon both the target capital structure and market conditions. The
Company also uses these sources to meet long-term debt and preferred and
preference stock redemption requirements (see Notes 3 and 5 to the Consolidated
Financial Statements).

     Cash Flows
     ----------

          Operating Activities
          --------------------

          Cash provided by operating activities in 1997 was $44.1 million, or 49
percent, lower than in 1996. The decrease was primarily due to an increase in
deferred gas costs ($36.7 million) and a decrease in accounts payable ($6.0
million).

          In 1996, cash provided by operating activities was $6.1 million, or 7
percent, higher than in 1995, primarily due to increased gas deliveries and the
related margin from weather-sensitive customers resulting from colder weather
and customer growth. The increase in margin in 1996 was partially offset by the
continuing effects of rate reductions effective in December 1994 and 1995 to
amortize credit balances in regulatory accounts.

          The Company has lease and purchase commitments related to its
operating activities which are financed with cash flows from operations (see
Note 13 to the Consolidated Financial Statements).

          Investing Activities
          --------------------

          Cash requirements for NW Natural's capital expenditures in 1997
totaled $115.9 million, up $32.5 million, or 39 percent, from 1996. The increase
included expenditures for expansion of the Mist underground storage facility
($10.8 million); completion of the new customer information system (CIS)
software development ($7.9 million); transportation equipment ($2.2 million);
expansion and reinforcement of the gas distribution system to accommodate
customer growth ($3.2 million); land purchases for a new service center ($1.6
million); and the upgrading of other computer system hardware and software ($1.5
million).

          The $16.2 million increase in capital expenditures in 1996 compared to
1995 resulted largely from higher amounts expended for the gas distribution
system in order to serve significant customer growth ($8.8 million); the ongoing
development of the new CIS which had been delayed in 1995 ($3.7 million); and
the development of a remote data terminal system ($1.9 million).

          NW Natural's construction expenditures are estimated at $90 million
for 1998. Over the five year period 1998 through 2002, these expenditures are
estimated to be $500 million to $550 million. The higher projected level of
capital expenditures over the next five years reflects continued high customer
growth, a major system reinforcement project and the development of additional
underground storage facilities. About half of the required funds are expected to
be internally generated, with the remainder to be funded through a combination
of long-term debt and equity securities with short-term debt providing liquidity
and bridge financing.

          NW Natural invested $3.0 million in both 1996 and 1997 in Canor's
exploration and production program to supplement Canor's internally-generated
funds.

          Financing Activities
          --------------------

          Cash provided by financing activities in 1997 totaled $76.8 million,
compared to cash used for financing of $6.5 million in 1996 and $7.2 million in
1995. The primary financing activities which accounted for the change from 1996
were NW Natural's sale of $90 million of its Medium-Term Notes in 1997 and the
net issuance of $39.3 million of commercial paper, partially offset by the
redemption of $27 million of long-term debt.

          Significant financing activity in 1996 consisted of NW Natural's sale
of $20 million of Medium-Term Notes, the net issuance of $21.2 million of
commercial paper and the redemption of $22 million of long-term debt.

          In 1995, financing activity consisted primarily of NW Natural's sales
of $33 million of common stock and $10 million of Medium-Term Notes, the
redemption of the remaining shares of the $2.375 series of Convertible
Preference Stock and a net decrease of $24.8 million of commercial paper.

     Ratios of Earnings to Fixed Charges
     -----------------------------------

          For the years ended December 31, 1997, 1996 and 1995, the Company's
ratios of earnings to fixed charges, computed using the Securities and Exchange
Commission method, were 2.99, 3.53 and 3.15, respectively. For this purpose,
earnings consist of net income before taxes plus fixed charges, and fixed
charges consist of interest on all indebtedness, the amortization of debt
expense and discount or premium, and the estimated interest portion of rentals
charged to income.

Contingent Liabilities
- ----------------------

          Like all companies with business application software programs, the
Company is affected by the "Year 2000" issue. Much of this software, which
includes NW Natural's customer service, operations, and financial systems, was
written using two digits to define the year, rather than four. Any of the
Company's software that is time-sensitive may recognize a date using "00" as the
year 1900 rather than 2000. This could result in the computer shutting down or
performing incorrect calculations.

          NW Natural has identified and is in the process of correcting the
systems within its control that could be affected by the Year 2000 issue. In
1997, the consultant that performed an assessment of NW Natural's application
software estimated that the cost of making its application source code for these
systems Year 2000-compliant would be about $4.0 million. NW Natural believes
that with the appropriate modifications, it will be able to operate its
time-sensitive software programs beyond the turn of the century.

          NW Natural has identified major vendors for which it depends on
products or services and is contacting such vendors to hear what plans they have
to correct problems they may face with Year 2000 compliance. The Company can
make no assurances regarding the Year 2000 compliance status of systems or
parties outside its control, and cannot assess the effect on it of any
non-compliance by such systems or parties.

          In December 1997, the OPUC authorized NW Natural to defer and amortize
over five years, commencing January 1, 1998, its incremental costs for
assessment, planning and renovation of systems for Year 2000 compliance.

Environmental Matters
- ---------------------

          NW Natural owns property in Linnton, Oregon, that is the site of a
former gas manufacturing plant that was closed in 1956. In 1993, pursuant to
Oregon Department of Environmental Quality (ODEQ) procedures, NW Natural
submitted a notice of intent to participate in the ODEQ's Voluntary Cleanup
Program and, in 1994, the site was listed on ODEQ's Confirmed Release List and
Inventory. During 1995, initial tests revealed environmental contamination, but
the extent or the estimated cost of remediation cannot yet be determined. NW
Natural continues to monitor this site.

          NW Natural expects that its costs of investigation and any remediation
at the Linnton site for which it may be responsible should be recoverable, in
large part, from insurance or through future rates. During the period from 1993
through 1997, NW Natural recorded as expense a total of $1.6 million for the
estimated costs of consultants' fees, ODEQ oversight and the voluntary
investigation.

          In 1996, the Eugene Water and Electric Board (EWEB) asked NW Natural
to participate in an investigation and the potential remediation of a 1.5 acre
site of a former manufactured gas plant in Eugene, Oregon. NW Natural purchased
the property in 1958, after the plant had been converted to a liquid propane gas
plant. It used the propane plant until 1960 when the system was converted to
natural gas, and continued to use the site as a service center until 1976 when
it was sold. To date, NW Natural has not agreed to participate in an
investigation of the site and has not obtained sufficient information to
determine the extent of its responsibility, if any, for remediation of the site.

Forward-Looking Statements
- --------------------------

          This report and other presentations made by the Company from time to
time may contain forward-looking statements within the meaning of Section 21E of
the Securities Exchange Act of 1934, as amended. Forward-looking statements
include statements concerning plans, objectives, goals, strategies, future
events or performance, and other statements which are other than statements of
historical facts. The Company's expectations, beliefs and projections are
expressed in good faith and are believed by the Company to have a reasonable
basis. However, each such forward-looking statement involves uncertainties and
is qualified in its entirety by reference to the following important factors
that could cause the actual results of the Company to differ materially from
those projected in such forward-looking statements: (i) prevailing governmental
policies and regulatory actions, including those of the Oregon Public Utility
Commission and the Washington Utilities and Transportation Commission, with
respect to allowed rates of return, industry and rate structure, purchased gas
and investment recovery, acquisitions and dispositions of assets and facilities,
operation and construction of plant facilities, present or prospective wholesale
and retail competition, changes in tax laws and policies and changes in and
compliance with environmental and safety laws and policies; (ii) weather
conditions and other natural phenomena; (iii) unanticipated population growth or
decline, and changes in market demand and demographic patterns; (iv) competition
for retail and wholesale customers; (v) pricing of natural gas relative to other
energy sources; (vi) unanticipated changes in interest rates or in rates of
inflation; (vii) unanticipated changes in operating expenses and capital
expenditures; (viii) capital market conditions; (ix) competition for new energy
development opportunities; and (x) legal and administrative proceedings and
settlements. All subsequent forward-looking statements, whether written or oral
and whether made by or on behalf of the Company, also are expressly qualified by
these cautionary statements.

          Any forward-looking statement speaks only as of the date on which such
statement is made, and the Company undertakes no obligation to update any
forward-looking statement to reflect events or circumstances after the date on
which such statement is made or to reflect the occurrence of unanticipated
events. New factors emerge from time to time and it is not possible for the
Company to predict all such factors, nor can it assess the impact of each such
factor or the extent to which any factor, or combination of factors, may cause
results to differ materially from those contained in any forward-looking
statement.

              MANAGEMENT'S RESPONSIBILITY FOR FINANCIAL STATEMENTS
              ----------------------------------------------------

          The financial statements in this report were prepared by management,
which is responsible for their objectivity and integrity. The statements have
been prepared in conformity with generally accepted accounting principles and,
where appropriate, reflect informed estimates based on judgments of management.
The responsibility of the Company's independent auditors is to render an
independent report on the financial statements.

          The Company's system of internal accounting controls is designed to
provide reasonable assurance that assets are safeguarded and transactions are
executed in accordance with management's authorizations, that transactions are
recorded to permit the preparation of financial statements in conformity with
orders of regulatory authorities and generally accepted accounting principles
and that accountability for assets is maintained. The Company's system of
internal controls has provided such reasonable assurances during the periods
reported herein. The system includes written policies, procedures and
guidelines, an organization structure that segregates duties and an established
program for monitoring the system by internal auditors. In addition, Northwest
Natural Gas Company has prepared and annually distributes to its employees a
Code of Ethics covering its policies for conducting business affairs in a lawful
and ethical manner. Ongoing review programs are carried out to ensure compliance
with these policies.

          The Board of Directors, through its Audit Committee, oversees
management's financial reporting responsibilities. The committee meets regularly
with management, the internal auditors, and representatives of the Company's
independent auditors. Both internal and external auditors have free and
independent access to the committee and the Board of Directors. No member of the
committee is an employee of the Company. The committee reports the results of
its activities to the full Board of Directors. Annually, the Audit Committee
recommends the nomination of independent auditors to the Board of Directors for
shareholder approval.

                        REPORT OF INDEPENDENT ACCOUNTANTS

February 20, 1998

To the Board of Directors and
Stockholders of NW Natural

In our opinion, the accompanying consolidated balance sheets and statements of
capitalization and the related consolidated statements of income, of cash flows
and of changes in earnings invested in the business present fairly, in all
material respects, the financial position of Northwest Natural Gas Company
(doing business as NW Natural) and its subsidiaries at December 31, 1997, and
the results of their operations and their cash flows for the year then ended, in
conformity with generally accepted accounting principles. These financial
statements are the responsibility of the Company's management; our
responsibility is to express an opinion on these financial statements based on
our audit. We conducted our audit of these statements in accordance with
generally accepted auditing standards which require that we plan and perform the
audit to obtain reasonable assurance about whether the financial statements are
free of material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the financial statements,
assessing the accounting principles used and significant estimates made by
management, and evaluating the overall financial statement presentation. We
believe that our audit provides a reasonable basis for the opinion expressed
above.

opinion on these financial statements based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the consolidated financial statements. An audit
also includes assessing the accounting principles used and significant estimates
made by management, as well as evaluating the overall financial statement
presentation. We believe that our audits provide a reasonable basis for our
opinion.

In our opinion, such consolidated financial statements present fairly, in all
material respects, the consolidated financial position of Northwest Natural Gas
Company and subsidiaries at December 31, 1996, and the results of their
operations and their cash flows for each of the two years in the period ended

NORTHWEST NATURAL GAS COMPANY
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
- --------------------------------------------------------------------------------

1.        SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:
- -----------------------------------------------------

Organization and Principles of Consolidation
- --------------------------------------------

          The consolidated financial statements include:
               Regulated utility:
               --Northwest Natural Gas Company (doing business as NW Natural)
               Non-regulated wholly-owned businesses:
               --NNG Financial Corporation (Financial Corporation)
               --Canor Energy, Ltd. (Canor)
               --Oregon Natural Gas Development Corporation (Oregon Natural)

          Oregon Natural was merged with and into NW Natural during the second
          quarter of 1996.

          Together these businesses are referred to herein as the "Company."
          Intercompany accounts and transactions have been eliminated.

          Investments in corporate joint ventures and partnerships in which the
          Company's ownership is 50 percent or less are accounted for by the
          equity method or the cost method (see Note 10).

          Certain amounts from prior years have been reclassified to conform
          with the 1997 presentation.

Use of Estimates
- ----------------

          The preparation of financial statements in conformity with generally
          accepted accounting principles requires management to make estimates
          and assumptions that affect reported amounts in the consolidated
          financial statements and accompanying notes. Changes in such estimates
          may affect amounts reported in future periods.

Industry Regulation
- -------------------

         The Company's principal business is the distribution of natural gas
         which is regulated by the Oregon Public Utility Commission (OPUC) and
         the Washington Utilities and Transportation Commission (WUTC).
         Accounting records and practices conform to the requirements and
         uniform system of accounts prescribed by these regulatory authorities
         in accordance with Statement of Financial Accounting Standards (SFAS)
         No. 71, "Accounting for the Effects of Certain Types of Regulation."

Utility Plant
- -------------

         NW Natural's utility plant is stated at original cost (see table in
         Note 10). When a depreciable unit of property is retired, the original
         cost is removed from both utility plant and the accumulated provision
         for depreciation together with the cost of removal, less any salvage.
         No gain or loss is recognized upon normal retirement.

         NW Natural's provision for depreciation of utility property, which is
         computed under the straight-line, age-life method in accordance with
         independent engineering studies and as approved by regulatory
         authorities, approximated 3.8 percent of average depreciable plant in
         both 1997 and 1996 and 4.2 percent in 1995. The rate of depreciation
         approximates the economic life of the utility property.

         Certain additions to utility plant include an allowance for funds used
         during construction (AFUDC), a non-cash item. AFUDC represents the cost
         of funds borrowed during construction and is calculated using actual
         commercial paper interest rates. If commercial paper borrowings are
         insufficient to finance the total work in progress, then a composite
         rate of interest on all debt, shown as a reduction to interest charges,
         and a return on equity funds, shown as other income, is used to compute
         AFUDC. While cash is not realized currently from AFUDC, it is realized
         in the ratemaking process over the service life of the related property
         through increased revenues resulting from higher rate base and higher
         depreciation expense. NW Natural's weighted average AFUDC rates were
         5.8 percent for 1997, 8.9 percent for 1996, and 5.3 percent for 1995.

Regulatory Accounts
- -------------------

         In applying SFAS No. 71, NW Natural has capitalized certain costs and
         benefits as regulatory assets and liabilities pursuant to orders of the
         state utility regulatory commissions, in general rate proceedings or
         expense deferral proceedings, in order to provide for recovery of
         revenues or expenses from, or refunds to, utility customers in future
         periods. At December 31, 1997 and 1996, regulatory tax assets were
         $56.9 million and $57.9 million, respectively, while other regulatory
         assets and liabilities (net) were $36.9 million and $8.2 million,
         respectively.

         If, in the future, NW Natural determines that all or a portion of these
         regulatory assets and liabilities no longer meets the criteria for
         ccontinued application of SFAS No. 71, it would be required to write
         off that portion which it could not recover or refund.

Cash and Cash Equivalents
- -------------------------

         For purposes of reporting cash flows, cash and cash equivalents include
         cash on hand and highly liquid temporary investments with original
         maturity dates of three months or less.

Unbilled Revenue
- ----------------

         NW Natural accrues for gas deliveries not billed to customers from the
         meter reading dates to month end.

Inventories
- -----------

         NW Natural's inventories of gas in storage and materials and supplies
         are stated at the lower of average cost or net realizable value.

Derivatives Policy
- ------------------

         NW Natural has a "Derivatives Policy" which allows up to a 100 percent
         hedge position in currency derivatives to match and lock-in prices on
         individual Canadian natural gas purchase transactions; interest rate
         derivatives to match specific outstanding debt instruments maturing in
         less than five years; and natural gas commodity derivatives to lock-in
         or cap prices on gas purchased for a future period under contracts with
         market-indexed pricing. The policy requires derivatives to be used
         within prescribed limitations and only in order to reduce price risk,
         so as to qualify for hedge accounting treatment. Changes in market
         values of foreign currency contracts, and gains or losses on commodity
         swap contracts, are deferred and recognized as adjustments to gas
         purchase costs upon concurrent settlement of these contracts (see Note
         12).

Income Taxes
- ------------

         NW Natural uses the liability method of accounting for deferred income
         taxes. Deferred tax liabilities and assets reflect the expected future
         tax consequences, based on enacted tax law, of temporary differences
         between the tax basis of assets and liabilities and their financial
         reporting amounts.

         Consistent with rate and accounting instructions of regulatory
         authorities, deferred income taxes are not currently collected for
         those temporary income tax differences where the prescribed regulatory
         accounting methods do not provide for current recovery in rates. NW
         Natural has recorded a regulatory tax asset for such amounts pending
         recovery from customers in future rates. These amounts are primarily
         differences between the book and tax basis of net utility plant in
         service. This asset balance was $56.9 million at December 31, 1997 and
         $57.9 million at December 31, 1996 (see Note 7).

         Investment tax credits on utility property additions and leveraged
         leases, which reduce income taxes payable, are deferred for financial
         statement purposes and amortized over the life of the related property
         or lease. Investment and energy tax credits generated by non-regulated
         subsidiaries are amortized over a period of one to five years.

Other Income
- ------------

         Other income consists of interest income, gain on the sale of assets,
         including non-recurring gains from the sale of Oregon Natural's
         underground gas storage assets, gathering system and gas producing
         properties to NW Natural in 1996 and 1995, investment income of
         Financial Corporation, and other miscellaneous income from merchandise
         sales, rent, the aircraft lease and other items.

Earnings Per Share
- ------------------

         The Company adopted SFAS No. 128, "Earnings Per Share", for the year
         ended December 31, 1997. SFAS No. 128 requires disclosure of basic and
         diluted earnings per share. All prior years have been restated to
         reflect the adoption of SFAS No. 128. Basic earnings per share are
         computed based on the weighted average number of common shares
         outstanding each year. Diluted earnings per share reflect the potential
         effects of the conversion of any outstanding convertible debentures and
         the exercise of outstanding stock options. Diluted earnings are
         calculated as follows:

2.       CONSOLIDATED SUBSIDIARY OPERATIONS:
- --------------------------------------------

         At December 31, 1997, the Company had two active wholly-owned
         subsidiaries, Financial Corporation and Canor. Another wholly-owned
         subsidiary, Oregon Natural, was merged into NW Natural during 1996.

NNG Financial Corporation
- -------------------------

         Financial Corporation provides short-term financing for Canor and has
         several financial investments, including investments as a limited
         partner in solar electric generating systems, windpower electric
         generating projects, a hydroelectric facility and low-income housing
         projects. It also holds interests in certain gas producing properties
         in the western United States (see Note 10).

Canor Energy, Ltd.
- ------------------

         Canor, an Alberta, Canada corporation, is engaged in natural gas and
         oil exploration, development and production in Alberta and
         Saskatchewan, Canada. Canor began operations in 1990 as a wholly-owned
         subsidiary of Oregon Natural. When Oregon Natural was merged into NW
         Natural during 1996, Canor became a wholly-owned subsidiary of NW
         Natural.

3.   CAPITAL STOCK:
- -------------------

Common Stock
- ------------

         At December 31, 1997, NW Natural had reserved 68,181 shares of common
         stock for issuance under the Employee Stock Purchase Plan, 737,153
         shares under its Dividend Reinvestment and Stock Purchase Plan, 833,858
         shares under its 1985 Stock Option Plan (see Note 4), 578,033 shares
         for future conversions of its 7-1/4 percent Convertible Debentures and
         3,000,000 shares under the Shareholder Rights Plan.

         During 1996, the Board of Directors adopted a Shareholder Rights Plan
         and declared a dividend of one Right for each outstanding share of
         common stock. Each Right entitles the shareholder to purchase one tenth
         of a share of common stock for $6.67. In the event that any person
         acquired more than 15 percent of the outstanding common stock, or
         should the Company be acquired in a merger or other business
         combination transaction, subject to the terms of the Rights Plan, the
         Right would become exercisable, entitling each holder (other than the
         acquiring person or group), for a purchase price equal to 10 times the
         current purchase price of the Right, to purchase that number of shares
         of common stock having a market value equal to 20 times the purchase
         price of the Right. The Rights will expire on March 15, 2006.

         Effective September 6, 1996, additional shares of common stock were
         distributed to shareholders of record on August 23, 1996, in connection
         with a three-for-two stock split. All share disclosures and per share
         data related to the common stock included in these financial statements
         are presented on a post-split basis. Amounts associated with common
         stock for years prior to the effective date of the stock split have
         been adjusted to reflect the split.

Redeemable Preference Stock
- ---------------------------

         The $6.95 Series of Preference Stock is not redeemable prior to
         December 31, 2002, but is subject to mandatory redemption on that date.

Redeemable Preferred Stock
- --------------------------

         The mandatory preferred stock redemption requirements aggregate $1.0
         million in both 1998 and 1999, and $0.8 million in each of the years
         2000, 2001 and 2002. These requirements are noncumulative. At any time
         NW Natural is in default on any of its obligations to make the
         prescribed sinking fund payments, it may not pay cash dividends on
         common stock or preference stock. Upon involuntary liquidation, all
         series of redeemable preferred stock are entitled to their stated
         value.

         The remaining shares of the $4.68 Series redeemable preferred stock
         were redeemed on June 2, 1997.

         The redeemable preferred stock is callable at stipulated prices, plus
         accrued dividends. At December 31, 1997, redemption prices were $100
         per share for the $4.75 Series. Shares of the $7.125 Series are
         redeemable on or after May 1, 1998 at a price of $104.75 per share
         decreasing each year thereafter to $100 per share on or after May 1,
         2008.

4.   STOCK OPTION AND PURCHASE PLANS:
- -------------------------------------

         NW Natural's 1985 Stock Option Plan (Plan) authorizes an aggregate of
         1,200,000 shares of common stock for issuance as incentive or
         non-statutory stock options. These options may be granted only to
         officers and key employees designated by a committee of NW Natural's
         Board of Directors.

         All options are granted at an option price not less than the market
         value at the date of grant and may be exercised for a period not
         exceeding 10 years from the date of grant. Option holders may exchange
         shares they have owned for at least one year, at the current market
         price, to purchase shares at the option price.

         Since the Plan's inception in 1985, options on 649,173 shares of common
         stock have been granted at prices ranging from $11.75 to $24.00 per
         share, and options on 55,296 shares have expired. NW Natural applies
         Accounting Principles Board (APB) Opinion No. 25, "Accounting for Stock
         Issued to Employees," and related interpretations, in accounting for
         its stock-based compensation plans. Accordingly, no compensation cost
         has been recognized for either the Plan or the employee stock purchase
         plan. Had compensation cost for NW Natural's two stock-based
         compensation plans been determined based on the fair value at the grant
         dates for awards under those plans in a manner consistent with the
         method determined under SFAS No. 123, "Accounting for Stock-Based
         Compensation," net income and earnings per share would have been
         reduced to the pro forma amounts shown below:

</TABLE>

         For purposes of the pro forma expense, the fair value of each option is
         estimated on the grant date using the Black-Scholes option pricing
         model with the following weighted-average assumptions used for grants
         in 1996 and 1995, respectively: a dividend yield of 5 and 5.4 percent;
         expected volatility of 22 and 21 percent; risk-free interest rates of 6
         and 7 percent; and, for both of such years, expected lives of seven
         years.

6.       NOTES PAYABLE AND LINES OF CREDIT:
- -------------------------------------------

         NW Natural has available through September 30, 1998, committed lines of
         credit with five commercial banks totaling $100 million, consisting of
         a primary fixed amount of $50 million plus an excess amount of up to
         $50 million available as needed, at NW Natural's option, on a monthly
         basis. Financial Corporation has available through September 30, 1998,
         committed lines of credit with two commercial banks totaling $20

         Corporation pay commitment fees but are not required to maintain
         compensating bank balances. The interest rates on borrowings under
         these lines of credit are based on current market rates as negotiated.

         Financial Corporation line of credit as of December 31, 1997 or 1996.

         NW Natural and Financial Corporation issue domestic commercial paper,
         which is supported by the committed bank lines, under agency agreements

8.       EMPLOYEE RETIREMENT PLANS:
- -----------------------------------

         NW Natural has two non-contributory defined benefit retirement plans
         covering all regular employees with more than one year of service. The
         benefits under the plans are based upon years of service and the
         employee's average compensation during the final years of service. NW
         Natural's funding policy is to make the annual contribution required by
         applicable regulations and recommended by its actuary. Plan assets
         consist primarily of marketable foreign and domestic equity securities,
         corporate obligations, U.S. government obligations and cash
         equivalents.

         The following table sets forth the amounts recognized in the financial
         statements and the combined funded status of the retirement plans:

</TABLE>

         Effective December 31, 1997, NW Natural changed the assumed discount
         rate used in determining the funded status of the plans from 7.50
         percent to 7.25 percent. The 7.25 percent discount rate was used in
         determining the funded status of the plans at year-end 1997 and 7.50
         percent was used to determine annual pension cost in 1997 and 1996. The
         7.25 percent discount rate will be used to determine funded status and
         pension cost in 1998.

         NW Natural has a qualified "Retirement K Savings Plan" under Internal
         Revenue Code Section 401(k) and a non-qualified "Executive Deferred
         Compensation Plan," for eligible employees. These plans are designed to
         enhance the existing retirement program of employees and to assist them
         in strengthening their financial security by providing an incentive to
         save and invest regularly. NW Natural's contributions to these plans in
         1997, 1996 and 1995 were $1.1 million, $1.0 million and $0.8 million,
         respectively.

         NW Natural has a non-qualified supplemental retirement plan for
         eligible executive officers which it is funding with trust-owned life
         insurance. The amount of coverage is designed to provide sufficient
         returns to recover all costs of the plan if assumptions made as to
         mortality experience, policy earnings, and other factors are realized.
         Expenses related to the plan were $1.3 million in both 1997 and 1996
         and $1.0 million in 1995.

9.       POSTRETIREMENT HEALTH CARE AND LIFE INSURANCE BENEFITS:
- ----------------------------------------------------------------

         The Company provides continued health care and life insurance coverage
         after retirement for exempt employees. These benefits and similar
         benefits for active employees are provided by insurance companies, and
         related premiums are based on the amount of benefits paid during the
         year.

         The accrued costs in excess of benefits paid relating to SFAS No. 106,
         "Employers' Accounting for Postretirement Benefits Other than
         Pensions," are not included in NW Natural's rates in Oregon. The staff
         of the OPUC has recommended that NW Natural's portion of these costs
         allocated to Oregon be authorized for recovery in rates only pursuant
         to a general rate case filing, and has recommended against the use of
         deferred accounting treatment for their recovery. NW Natural is
         charging the Oregon portion of these costs to expense. In Washington,
         the WUTC's order in NW Natural's 1997 general rate case authorized NW
         Natural to begin amortizing the deferred SFAS No. 106 costs
         attributable to Washington operations that had accrued since adoption
         of SFAS No. 106 in 1993, to be collected from customers over a five
         year period. Additionally, the ongoing annual SFAS No. 106 cost
         relating to Washington operations was placed into rates and deferrals
         were discontinued.

</TABLE>

         The unrecognized transition obligation is being amortized over a period
         of 20 years beginning January 1, 1993. The assumed health care cost
         trend rate used in measuring the accumulated postretirement benefit
         obligation for pre-Medicare eligibility is 8.5 percent for 1998; 8
         percent for 1999; 7.5 percent for 2000; 7 percent for 2001; 6.5 percent
         for 2002; then decreasing over the next five years to 4 percent. The
         assumed rate for the HMO plan is 5 percent for 1998; 4.5 percent for
         1999; and 4 percent for the next eight years. The assumed rate for
         post-Medicare eligibility is 8 percent for 1998; 7.5 percent for 1999;
         7 percent for 2000; 6.5 percent for 2001; 6 percent for 2002; then
         decreasing over the next five years to 4 percent. A
         one-percentage-point change in the assumed health care cost trend rate
         for each year would adjust the accumulated postretirement benefit
         obligation and net postretirement health care cost as of December 31,
         1997 by approximately 14.8 percent and 16.1 percent, respectively. The
         assumed discount rate used in determining the accumulated
         postretirement benefit obligation was 7.25 percent at December 31,
         1997, 8.0 percent at December 31, 1996, and 7.5 percent at December 31,
         1995.

         Financial Corporation has invested in solar electric generation plants
         located near Barstow, California. Power generated by these plants is
         sold to Southern California Edison Company under long-term contracts.
         Financial Corporation's ownership interests in these projects range
         from 4.0 percent to 5.3 percent.

         Financial Corporation also has invested in U. S. Windpower Partners
         electric generating projects, with facilities located near Livermore
         and Palm Springs, California. The wind-generated power is sold to
         Pacific Gas and Electric Company and Southern California Edison Company
         under long-term contracts. Financial Corporation's ownership interests
         in these projects range from 8.5 percent to 41 percent.

         In 1987, Oregon Natural purchased a Boeing 737-300 aircraft which was

- ------------------------------------------------------------------------------------
</TABLE>

         Fair value of the redeemable preference stock and the redeemable
         preferred stock was estimated using quoted market prices. Interest
         rates that are currently available to the Company for issuance of debt
         with similar terms and remaining maturities were used to estimate fair
         value for debt issues.

         The carrying amount of long-term notes receivable was stated at
         estimated fair value at December 31, 1997 and 1996.

12.  USE OF FINANCIAL DERIVATIVES:
- -----------------------------------

         In connection with its Canadian gas purchase commitments, NW Natural
         uses foreign currency forward contracts to hedge against fluctuations
         in currency values. The forward contracts have terms ranging up to 12
         months. Such contracts are purchased in an amount up to 100 percent but
         not less than 80 percent of estimated daily requirements for commodity
         gas purchased in Canadian currency from gas suppliers in Canada. The
         notional amount of these contracts at December 31, 1997 totaled $5.6
         million, and, if settled on that date, NW Natural would have realized a
         negligible loss on these contracts.

         As part of an overall strategy to maintain an acceptable level of
         exposure to the risk of gas price fluctuations, NW Natural has
         developed a targeted mix of fixed-rate and cap-protected natural gas
         commodity contracts versus variable rate contracts. To efficiently
         manage this mix, NW Natural uses natural gas commodity swap and cap
         agreements to effectively convert the gas purchase commitments into an
         acceptable fixed-rate and capped rate mix. NW Natural uses natural gas
         commodity swap agreements to convert certain long-term gas purchase
         contracts from floating prices to fixed prices. Under the commodity
         swap agreements, NW Natural receives or makes payments based on the
         differential between a specified price and the actual price of natural
         gas as measured by price indices relating to the market area where it
         purchases the gas. The swap agreements have terms ranging up to 12
         months. At December 31, 1997 and 1996, NW Natural had cap and swap
         agreements with broker-dealers to cover notional quantities of 131,635
         and 30,000 million British Thermal Units (MMBtu) per day of gas,
         respectively. Under the swap agreements in effect at December 31, 1997,
         NW Natural pays fixed prices averaging $1.687 per MMBtu. In return, it
         receives a price that varies from month to month with market
         conditions. The notional amount of the swap agreements at December 31,
         1997 was $23 million, and, if settled on that date, NW Natural would
         have realized a loss on these swaps of $4.4 million. (See Note 1,
         "Derivatives Policy," for a summary of accounting for gains and
         losses.)

13.  COMMITMENTS AND CONTINGENCIES:
- -----------------------------------

         Lease Commitments
         -----------------

         Future lease commitments are: $5.3 million in 1998; $2.8 million in
         1999; $2.5 million in 2000; $2.3 million in 2001; and $2.1 million in
         2002. Thereafter, total commitments amount to $6.2 million. These
         commitments principally relate to the lease of NW Natural's office
         headquarters, vehicles and computer systems.

         Total rental expense for 1997, 1996 and 1995 was $ 6.4 million, $5.4
         million and $5.3 million, respectively.

         Purchase Commitments
         --------------------

         NW Natural has signed agreements providing for the availability of firm
         pipeline capacity under which it must make fixed monthly payments for
         contracted capacity. The pricing component of the monthly payment is
         established, subject to change, by U.S. or Canadian regulatory bodies.
         In addition, NW Natural has entered into long-term agreements to
         release firm pipeline capacity. The aggregate amounts of these
         agreements were as follows at December 31, 1997:

         NW Natural's total payments of fixed charges under capacity purchase
         agreements in 1997, 1996 and 1995 were $76.7 million, $73.4 million and
         $62.2 million, respectively. Included in the amounts for 1997, 1996 and
         1995 were reductions for capacity release sales totaling $4.2 million,
         $4.2 million and $4.8 million, respectively. In addition, NW Natural is
         required to pay per-unit charges based on the actual quantities shipped
         under the agreements. In certain of NW Natural's take-or-pay purchase
         commitments, annual deficiencies may be offset by prepayments subject
         to recovery over a longer term if future purchases exceed the minimum
         annual requirements.

         Environmental Matters
         ---------------------

         NW Natural owns property in Linnton, Oregon, that is the site of a
         former gas manufacturing plant that was closed in 1956. In 1993,
         pursuant to Oregon Department of Environmental Quality (ODEQ)
         procedures, NW Natural submitted a notice of intent to participate in
         the ODEQ's Voluntary Cleanup Program and, in 1994, the site was listed
         on ODEQ's Confirmed Release List and Inventory. During 1995, initial
         tests revealed environmental contamination, but the extent or the
         estimated cost of remediation cannot yet be determined. NW Natural
         continues to monitor this site.

         NW Natural expects that its costs of investigation and any remediation
         at the Linnton site for which it may be responsible should be
         recoverable, in large part, from insurance or through future rates.
         During the period from 1993 through 1997, NW Natural recorded as
         expense a total of $1.6 million for the estimated costs of consultants'
         fees, ODEQ oversight and the voluntary investigation.

         In 1996, the Eugene Water and Electric Board (EWEB) asked NW Natural to
         participate in an investigation and the potential remediation of a 1.5
         acre site of a former manufactured gas plant in Eugene, Oregon. NW
         Natural purchased the property in 1958, after the plant had been
         converted to a liquid propane gas plant. It used the propane plant
         until 1960 when the system was converted to natural gas, and continued
         to use the site as a service center until 1976 when it was sold.
         Although NW Natural never operated the manufactured gas plant, EWEB has
         contended that NW Natural's activities on the site may have exacerbated
         prior contamination. To date, NW Natural has not agreed to participate
         in an investigation of the site and has not obtained sufficient
         information to determine the extent of its responsibility, if any, for
         remediation of the site.

         Litigation
         ----------

         In July 1995, a jury in an Oregon state court returned a verdict
         against NW Natural in the case of Northwest Natural Gas Company v.
                                           --------------------------------
         Chase Gardens, Inc. (Lane County Circuit Court Case No. 16-91-01370).
         -------------------
         The Oregon Court of Appeals (Oregon Court of Appeals Case No. CA
         A90481) affirmed the trial court decision in February 1997. The Oregon
         Supreme Court agreed to hear the case on appeal and is expected to
         render a final ruling during 1998. NW Natural recorded a charge of $5.6
         million in the fourth quarter of 1996, equivalent to 15 cents a share,
         as a reserve against payment of the judgment, costs and post-judgment
         interest from the case.

         The Company is party to certain other legal proceedings in which
         claimants seek material amounts. Although it is not possible to predict
         the outcome with certainty, based upon the opinions of legal counsel,
         management does not expect disposition of these matters to have a
         materially adverse effect on the Company's financial position, results
         of operations or cash flows.

* Quarterly earnings per share are based upon the average number of common
shares outstanding during each quarter. Because the average number of shares
outstanding has increased in each quarter shown, the sum of quarterly earnings
may not equal earnings per share for the year. Variations in earnings between
quarterly periods are due primarily to the seasonal nature of the Company's
business.

** Results for the fourth quarter of 1996 include a charge equivalent to 15
cents a share resulting from a judgment against NW Natural in litigation dating
from 1995, and an adjustment reducing tax expense by $1.9 million, or 8 cents a
share, for reversal of deferred tax amounts provided in prior years.

                                   ARTICLE I.

                                     OFFICES

     SECTION 1. OFFICE. The principal office of the company shall be located in
the City of Portland, Oregon. The company also may have offices at such other
places both within and without the State of Oregon as the board of directors
from time to time may determine.

         SECTION 2. REGISTERED OFFICE. The registered office of the company
required by law to be maintained in the state shall be at the same location as
the principal office unless otherwise designated by resolution of the board of
directors.

                                   ARTICLE II.

                            MEETINGS OF SHAREHOLDERS

         SECTION 1. ANNUAL MEETING. The annual meeting of shareholders of the
company for the election of directors and for the transaction of other business
shall be held at the company's office in the City of Portland, Oregon, or such
other place in that City as shall be determined by the board of directors, on
the fourth Thursday of May in each year, unless such day shall be a legal
holiday, in which event such meeting shall be held on the next business day. If
such meeting shall not be held on such day in any year, it shall be held within
60 days thereafter on such day as shall be fixed by the board of directors and
be specified in the notice of the meeting. Every such meeting shall be held at
the hour of two o'clock p.m., or at such other hour as shall be fixed by the
board and specified in such notice.

         SECTION 2. SPECIAL MEETINGS. Special meetings of the shareholders of
the company may be called by the board of directors or the holders of not less
than one-tenth of all shares entitled to vote at the meeting. Each special
meeting shall be held for such purposes, at such place in the City of Portland,
Oregon, and at such time as shall be specified in the notice thereof.

         SECTION 3. NOTICE. Written or printed notice stating the place, day and
hour of the meeting and, in case of a special meeting, the purpose or purposes
for which the meeting is called, shall be delivered not less than 10 nor more
than 50 days before the date of the meeting, either personally or by mail, by or
at the direction of the board of directors or the persons calling the meeting,
to each shareholder of record entitled to vote at such meeting.

         SECTION 4. FIXING RECORD DATE. For the purpose of determining
shareholders entitled to notice of or to vote at any meeting of shareholders, or
any adjournment thereof, or entitled to receive payment of any dividend, or in
order to make a determination of shareholders for any other proper purpose, the
board of directors may fix in advance a date as the record date for any such
determination of shareholders, such date in any case to be not more than 50 days
and, in the case of a meeting of shareholders, not less than 10 days prior to
the date on which the particular action requiring such determination of
shareholders is to be taken. If no record date is fixed for the determination of
shareholders entitled to notice of or to vote at a meeting of shareholders, or
shareholders entitled to receive payment of a dividend, the date on which notice
of the meeting is mailed or the date on which the resolution of the board
declaring such dividend is adopted, as the case may be, shall be the record date
for such determination of shareholders. When a determination of shareholders
entitled to vote at any meeting of shareholders has been made as provided in
this section, such determination shall apply to any adjournment thereof.

         SECTION 5. RECORD OF SHAREHOLDERS. The officer or agent having charge
of the transfer books for shares of the company shall make, at least 10 days
before each meeting of shareholders, a complete record of the shareholders
entitled to vote at such meeting or any adjournment thereof, arranged in
alphabetical order with the address of and the number of shares held by each,
which record, for a period of 10 days prior to such meeting, shall be kept on
file at the registered office of the company and shall be subject to inspection
by any shareholder at any time during usual business hours. Such record also
shall be produced and kept open at the time and place of the meeting and shall
be subject to the inspection of any shareholder during the whole time of the
meeting. The original transfer books for shares shall be prima facie evidence as
to who are the shareholders entitled to examine such record or transfer books or
to vote at any meeting of the shareholders.

         SECTION 6. QUORUM. A majority of the shares of the company entitled to
vote, represented in person or by proxy, shall constitute a quorum at all
meetings of shareholders. If a quorum is present, in person or by proxy, the
affirmative vote of a majority of the shares represented at the meeting and
entitled to vote on the subject matter shall be the act of the shareholders,
unless the vote of a greater number, or voting by classes, is required by law or
the Restated Articles of Incorporation.

              If a quorum shall not be represented at any meeting of
shareholders, the shareholders represented may adjourn the meeting from time to
time without further notice. At such adjourned meeting, at which a quorum shall
be present or represented, any business may be transacted which might have been
transacted at the meeting as originally noticed. The shareholders represented at
a duly organized meeting may continue to transact business until adjournment,
notwithstanding the withdrawal of enough shareholders to leave less than a
quorum.

         SECTION 7. VOTING. Each outstanding share, regardless of class, shall
be entitled to one vote on each matter submitted to a vote at a meeting of
shareholders, except to the extent that the voting rights of the shares of any
class or classes are limited or denied by law or the Restated Articles of
Incorporation. At each election of directors holders of shares of common stock
have the right to cumulative voting as provided for in the Restated Articles of
Incorporation. A shareholder may vote either in person or by proxy executed in
writing by the shareholder or by his or her duly authorized attorney-in-fact.
Such proxy shall be filed with the secretary of the company before or at the
time of the meeting.

         SECTION 8. CONDUCT OF MEETINGS. Every meeting of shareholders shall be
presided over by the chairman of the board, in his or her absence by the
president, in their absence by a vice president or, if none be present, by a
chairman appointed by the shareholders present at the meeting. The minutes of
such meeting shall be recorded by the secretary or an assistant secretary but,
if neither be present, by a secretary appointed for that purpose by the chairman
of the meeting.

elected a director, but a director may serve until the next annual meeting of

         SECTION 2. CHAIRMAN OF THE BOARD. The board of directors may elect one
of its members as chairman of the board. The chairman of the board, if that
position be filled, shall preside at all meetings of the shareholders and the

be prescribed by the board of directors. If there shall be no chairman of the
board, or in his or her absence or disability, the president also shall exercise
the duties and responsibilities of that position.

Transportation Rep., PNW Division
PanEnergy Trading and Market Services, LLC

Subject:          Letter Agreement Regarding Firm Transportation and Supply
                  ---------------------------------------------------------

Dear Ms. Flaim:

         Confirming your recent conversation and correspondence with Randy
Friedman, PanEnergy Trading and Market Services, LLC/Inland Pacific Energy
Services Corp. (PanEnergy) and Northwest Natural Gas (NNG) hereby agree to the
following:

1. PanEnergy will release and assign to NNG 5,000 Dth/day of its Northwest
Pipeline (NWP) firm transportation capacity at the maximum applicable NWP rate.
There will be no recall or other special provisions. Sumas will be the primary
receipt point for all 5,000 Dth/day. The primary delivery points will consist of
Vanalco (2,200 Dth/day), Rivergate (2,000 Dth/day) and Portland West (800
Dth/day). The assignment will commence November 1, 1997, continuing through the
primary term of PanEnergy's capacity contract with NWP, i.e., March 31, 2008,
and year-to-year thereafter at NNG's option.

2. PanEnergy consents to permanent changes made by NNG to the primary delivery
points specified above as long as such points remain within or adjacent to NNG's
service territory in northwest Oregon and southwest Washington. It is understood
that NNG must gain approval for any such changes from Northwest Pipeline.

3. NNG will provide PanEnergy with at least 60 days prior notice if NNG decides,
in its sole judgment, not to continue the capacity assignment after the end of
the primary term or beyond any annual extension after March 31, 2008. If NNG so
elects to terminate the assignment, it will return 5,000 Dth/day to PanEnergy
with receipt capacity at Sumas. The delivery points will be as specified in
section 1 above, subject to any modifications made pursuant to section 2 above.

4. PanEnergy will perform the above capacity assignment using NWP's electronic
bulletin board process within 10 working days of the execution date of this
Letter Agreement, or such later date as may be mutually agreeable.

5. PanEnergy warrants that the firm capacity it is assigning to NNG will be free
and clear of all adverse claims, liens or other encumbrances. PanEnergy remains
financially liable for all costs or penalties incurred using this capacity prior
to November 1, 1997.

6. NNG will enter into a 1-year contract to purchase 5,000 Dth/day (plus NWP
fuel) from PanEnergy commencing November 1, 1997, for delivery into NWP at
market competitive prices. This transaction may be structured as a baseload
contract, as synthetic storage (NNG buys in the summer and PanEnergy delivers in
the winter), or as such other arrangement as is mutually agreeable. Negotiations
are to be concluded no later than September 30, 1997.

7. NNG extends to PanEnergy a right of first refusal on the first 5,000 Dth/day
(plus NWP fuel) of 1-year supply contracted by NNG for delivery into Northwest
Pipeline on or after November 1, 1998. This right continues to and through the
contract year commencing November 1, 2007, after which it expires.

8. The right of first refusal shall mean that PanEnergy has the right to match
or beat any bona fide offers for 1-year supply received by NNG. If PanEnergy
does so, NNG will contract with PanEnergy for the first 5,000 Dth/day of its
1-year supply requirement. To exercise this right, PanEnergy must respond within
10 working days of notice by NNG of bona fide offers for 1-year supply and NNG's
intent to so contract.

9. The right of first refusal does not apply to or displace any of NNG's
currently existing 1-year or longer gas supply contracts.

10. The right of first refusal is granted solely to PanEnergy and its
successors, and does not extend to any of PanEnergy's assignees, transferees or
trustees, unless NNG otherwise consents.

         Please indicate your acceptance with the foregoing by executing below
and returning one original to Mr. Friedman's attention.

                              Very truly yours,

                              /s/ W. R. Harper, Jr.

                          NORTHWEST NATURAL GAS COMPANY

                      EXECUTIVE DEFERRED COMPENSATION PLAN

                                1990 RESTATEMENT

         This Amendment No. 3 to the Northwest Natural Gas Company Executive
Deferred Compensation Plan, 1990 Restatement (the "Plan"), is effective as of
January 1, 1998 and has been executed as of this 18th day of December, 1997.

         The Plan is hereby amended as follows:

         FIRST:  Section 4.2 is amended to read as follows:

4.2      Matching Contribution. The Corporation shall credit a Matching
         Contribution to the Executive's Account with respect to Deferral
         Commitments. The amount of the Matching Contribution shall be
         twenty-five percent (25%) of the first eight percent (8%) of the
         Executive's Elective Deferred Compensation during the calendar year,
         but the total Matching Contribution shall not exceed two percent (2%)
         of the Executive's Compensation during such calendar year. The Matching
         Contribution shall be reduced by the amount, if any, the Corporation
         has contributed as a matching contribution for the Executive to the
         Corporation's Retirement K Savings Plan. Matching Contributions shall
         be credited to the Executive's Account on the last day of the calendar
         quarter in which the Matching Contribution was earned. If the Executive
         is not eligible to participate in the Retirement K Savings Plan, no
         Matching Contributions shall be made to this Plan until such time of
         eligibility.

         SECOND:  Except as provided herein, all other plan provisions shall
remain in full force and effect.

         IN WITNESS WHEREOF, Northwest Natural Gas Company has caused this
Amendment No. 3 to be executed as of the date first written above.

                          NORTHWEST NATURAL GAS COMPANY

                      DIRECTORS DEFERRED COMPENSATION PLAN

1. RESTATEMENT. The Board of Directors (the "Board") of Northwest Natural Gas
Company (hereinafter, the "Company") adopted a Director's Deferred Compensation
Plan (hereinafter, the "Plan") effective June 1, 1981, which was previously
restated effective as of January 1, 1988 and then amended effective as of
February 23, 1995. The existing Plan is amended by this Restatement, effective
as of December 1, 1997.

2.       Election by Directors.
         ----------------------

     (1) ELIGIBILITY. Any director of the Company or any corporation or other
entity affiliated with or subsidiary to it (a "Director") is eligible to elect
to defer receipt of all or part of (i) the fees paid to him or her as a Director
or as a member of a committee of the Board ("Fees"), or (ii) the shares of
restricted common stock of the Company ("Common Stock") awarded to the Director
under the Company's Non-Employee Directors Stock Compensation Plan ("NEDSCP
Shares").

     (2) DEFERRAL OF FEES. Any Director may elect, prior to the beginning of any
calendar year, to defer receipt of fees for that calendar year, whether or not
the fees are actually payable in that calendar year; and any newly elected
Director prior to assuming office may elect to defer receipt of fees commencing
after the date on which the Director assumes office. Any election under the
preceding sentence shall apply only to fees earned subsequent to the date the
election is filed. Total deferrals of Fees by a Director in a calendar year must
be at least $1,500.

     (3) DEFERRAL OF NEDSCP SHARES. Any Director may elect, prior to the
beginning of any calendar year, to defer receipt of unvested NEDSCP Shares that
are scheduled to vest in that calendar year; and any newly elected Director
prior to assuming office may elect to defer receipt of NEDSCP Shares that will
vest in the remainder of the calendar year after the date on which the Director
assumes office. Total deferrals of NEDSCP Shares by a Director in a calendar
year must be at least 100% of the NEDSCP Shares scheduled to vest in that year.
No deferral shall be allowed of NEDSCP Shares as to which a Director has made an
election under Section 83(b) of the Internal Revenue Code.

     (4) CONTINUATION AND MODIFICATION. An election to defer Fees or NEDSCP
Shares by a Director shall automatically continue from year to year unless the
Director terminates or modifies the election by written request. Any such
termination or modification shall not become applicable until the calendar year
following the year in which such written termination or modification is filed.
In the event of a termination of a deferral election, any amounts already
deferred by a Director shall not be paid until he or she ceases to serve as a
Director, and then only pursuant to the terms, conditions, limitations and
restrictions of the Plan.

3.       Accounts.
         ---------

     (1) ACCOUNTS. The Company shall establish on its books one, two or three
separate accounts (individually, an "Account" and collectively, the "Accounts")
for each Director who participates in the Plan: a Stock Account, a Cash Account,
and/or for each person who is a Director as of January 1, 1998, a Retirement
Benefit Account. The number of NEDSCP Shares deferred by a Director shall be
credited to the Stock Account. Fees deferred by a Director shall be credited to
the Stock Account or the Cash Account as elected by the Director at the time the
Director elects to defer Fees. Such election may be divided between the two
Accounts in increments of 25 percent of the deferred Fees covered by the
election. An election between the Stock Account and the Cash Account shall be
irrevocable as to the deferred Fees covered by the election and no transfers
between the Stock Account and the Cash Account shall be permitted. The credit
for deferred Fees shall be entered on the Company's books of account each month
at the time that Fees are paid to other Directors who do not elect to defer the
payment of such Fees. The credit for deferred NEDSCP Shares shall be entered on
the Company's books of account as soon as practicable after January 1 of the
year subject to the deferral. No special fund shall be established nor shall any
notes or securities be issued by the Company with respect to a Director's
Accounts.

     (2) STOCK ACCOUNT. A Director's Stock Account shall be denominated in
shares of Common Stock, including fractional shares. With respect to each amount
of Fees deferred to a Director's Stock Account, the Stock Account shall be
credited with a number of shares equal to the deferred Fees divided by the
purchase price for shares of Common Stock under the Company's Dividend
Reinvestment and Stock Purchase Plan (the "DRSPP") on the Investment Date (as
defined in the DRSPP) next succeeding the day the deferred Fees would have been
paid if not for the deferral. As of each date for payment of dividends on the
Common Stock, the Stock Accounts shall be credited with an additional number of
shares (including fractional shares) equal to the amount of dividends that would
be paid on the number of shares recorded as the balance of the Stock Account as
of the record date for such dividend divided by the purchase price for shares of
Common Stock under the DRSPP for dividends reinvested on such payment date.

     (3) FORFEITURE OF NEDSCP SHARES. If any NEDSCP Shares deferred by a
Director under this Plan are forfeited under the terms of the Company's
Non-Employee Directors Stock Compensation Plan, the Director's Stock Account
shall be reduced by the number of shares so forfeited.

     (4) RETIREMENT BENEFIT ACCOUNT. A Director's Retirement Benefit Account
shall be denominated in shares of Common Stock, including fractional shares.
Effective as of January 1, 1998, Section 5 of Article III of the Company's
Bylaws has been amended to eliminate with respect to all persons who are
Directors as of January 1, 1998 a provision for a retirement benefit payable to
Directors who retire from the Board at age 72 with at least 10 years of service.
Effective as of January 1, 1998, the Retirement Benefit Account of each person
who is a Director on that date shall be credited with a number a shares of
Common Stock determined by the Company as a replacement for the prior retirement
benefit. As of each date for payment of dividends on the Common Stock, the
Retirement Benefit Accounts shall be credited with an additional number of
shares (including fractional shares) equal to the amount of dividends that would
be paid on the number of shares recorded as the balance of the Retirement
Benefit Account as of the record date for such dividend divided by the purchase
price for shares of Common Stock under the DRSPP for dividends reinvested on
such payment date. The Retirement Benefit Account of a Director shall be
canceled, and all amounts credited to such account shall be forfeited, if the
Director ceases to be a Director before reaching age 72 or before serving as a
Director for 10 years; provided, however, that all Retirement Benefit Accounts
will be fully vested and noncancellable upon a Change in Control as defined in
Paragraph 8.

     (5) STATEMENT OF ACCOUNT. At the end of each calendar quarter, a report
shall be issued by the Company to each participating Director setting forth the
balances of the Director's Accounts under the Plan. The credit entries made to a
Director's Accounts constitute merely a general obligation of the Company to pay
such Accounts to the Director, or to his or her beneficiary or estate when due
under the Plan.

     4. INTEREST. Interest shall be credited to the Cash Account balance
(including both principal and interest) of each participating Director based on
the balance at the end of each calendar quarter. The rate of interest to be
applied at the end of each calendar quarter shall be the quarterly equivalent of
an annual yield that is three (3) percentage points higher than the annual yield
on 30-Year, Long-Term Government Securities for the preceding quarter, as
published by the Federal Reserve Board (or any successor thereto), or if such
index is no longer published, a substantially similar index selected by the
Board. At no time shall the interest rate be less than six percent (6%)
annually. The interest credit shall continue to be applied to the Cash Account
of a Director, even if ceasing to serve as a Director, until all amounts
credited to his or her Cash Account have been paid. Said interest shall be
calculated quarterly, based upon the average daily balance of the Director's
Cash Account since the preceding calendar quarter, after giving effect to any
reduction in the Cash Account as a result of any payments. The remaining annual
payments will be recomputed to reflect the additional interest credits.

5.       Terms of Payment.
         -----------------

     (1) PLAN BENEFITS. The amounts contained in a Director's Accounts are
subject to the terms of payment as set forth in this paragraph. When a Director
ceases to serve as a Director of the Company, either by retirement or otherwise,
or upon a Change in Control as defined in Paragraph 8, the individual shall be
entitled to payment of the amounts in his or her Accounts.

     (2) TIMING OF BENEFIT PAYMENT. At the time the Director elects to defer
Fees or NEDSCP Shares, and with respect to Retirement Benefit Accounts before
January 1, 1998, the Director may designate the number of annual installments,
not to exceed ten, in which the applicable Account balance shall be paid, or the
Director may elect to receive such Account balance in a lump sum payment, or in
a combination of a partial lump sum and the remainder in installment payments.
Such elections may be modified by written request at any time with respect to
Fees earned or NEDSCP Shares that vest in subsequent calendar years, but shall
be irrevocable with respect to Retirement Benefit Accounts and with respect to
Fees earned and NEDSCP Shares that vest during the year the request is filed and
prior years as well as all interest and dividend credits with respect to such
amounts.

     (3) FORM OF BENEFIT PAYMENT. Benefits payable to a Director from a Stock
Account or a Retirement Benefit Account shall only be paid to such Director as a
distribution of Common Stock plus cash for fractional shares. Benefits payable
to a Director from a Cash Account shall only be paid to such Director in cash.

     (4) COMMENCEMENT OF PAYMENT. Any lump sum payment or the first annual
installment payment owed to a Director shall not be due earlier than the first
business day of January in the year following the year in which he or she ceases
to serve as a Director of the Company. In the event a Director terminates the
election to defer Fees or NEDSCP Shares, any Fees or NEDSCP Shares already
deferred shall not be payable to the Director until such time as he or she
ceases to serve as a Director, and then only subject to the terms and conditions
contained herein. The provisions of this paragraph are subject to the terms of
Paragraph 6 covering the death of a Director and to the terms of Paragraph 8
covering a Change in Control.

     (5) PAYMENT TO GUARDIAN. If a benefit under the Plan is payable to a minor
or a person declared incompetent or to a person incapable of handling the
disposition of his property, the Committee may direct payment of such Plan
benefit to the guardian, legal representative or person responsible for the care
and custody of such minor, incompetent or person. The Committee may require
proof of incompetency, minority, incapacity or guardianship as it may deem
appropriate prior to distribution of the Plan benefit. Such distribution shall
completely discharge the Committee and the Company from all liability with
respect to such benefit.

     (6) WITHHOLDING; PAYROLL TAXES. The Company shall withhold from payments
made hereunder any taxes required to be withheld from such payments under
federal, state or local law.

6.       Death of Director.
         ------------------

     (1) PLAN DEATH BENEFIT. Upon the death of a Director or a former Director
prior to the receipt of the full amount credited to his or her Accounts, the
balance of the Director's Accounts shall be paid to the designated beneficiary
or beneficiaries in the manner elected in writing by the Director at the time of
the deferral election, or if no such election is made, by lump sum payment.

     (2) BENEFICIARY. At the time a Director elects to defer payment of Fees or
NEDSCP Shares, and with respect to Retirement Benefit Accounts before January 1,
1998, the Director may designate a beneficiary or beneficiaries. If greater than
50% of the benefit is designated to a beneficiary other than the Director's
spouse, such beneficiary designation shall be consented to by the Director's
spouse. Such designation may be changed by the Director at any time without the
consent of a beneficiary, subject to the spousal consent requirement above. If
no designated beneficiary survives the Director or former Director, the balance
of the Director's Accounts shall be paid to the Director's estate.

7.       Administration.
         ---------------

     (1) COMMITTEE DUTIES. This Plan shall be administered by the Organization
and Executive Compensation Committee of the Board (the "Committee"). The
Committee shall have responsibility for the general administration of the Plan
and for carrying out its intent and provisions. The Committee shall interpret
the Plan and have such powers and duties as may be necessary to discharge its
responsibilities. The Committee may, from time to time, employ other agents and
delegate to them such administrative duties as it sees fit, and may from time to
time consult with counsel who may be counsel to the Company.

     (2) BINDING EFFECT OF DECISIONS. The decision or action of the Committee in
respect of any question arising out of or in connection with the administration,
interpretation and application of the Plan and the rules and regulations
promulgated hereunder shall be final and conclusive and binding upon all persons
having any interest in the Plan.

     (3) INDEMNITY OF COMMITTEE. To the extent permitted by applicable law, the
Company shall indemnify, hold harmless and defend the members of the Committee
against any and all claims, loss, damage, expense or liability arising from any
action or failure to act with respect to this Plan, provided that the members of
the Committee were acting in accordance with the applicable standard of care.

     8. CHANGE IN CONTROL. In the event of a Change in Control, any lump sum
payment or the first annual payment, as elected by the Director in Paragraph
5(b) above, shall be made immediately, with any subsequent annual payments to be
made thereafter in the manner elected by the Director in the applicable deferral
election. For purposes of this Plan, a "Change in Control" of the Company shall
mean the occurrence of any of the following events:

               (a)  The approval by the shareholders of the Company of:

                    (1) any consolidation, merger or plan of share exchange
               involving the Company (a "Merger") in which the Company is not
               the continuing or surviving corporation or pursuant to which
               shares of Common Stock would be converted into cash, securities
               or other property, other than a Merger involving shares of Common
               Stock in which the holders of shares of Common Stock immediately
               prior to the Merger have the same proportionate ownership of
               common stock of the surviving corporation immediately after the
               Merger;

                     (2) any sale,lease,exchange or other transfer (in one
               transaction or a series of related transactions) of all, or
               substantially all, the assets of the Company; or

                     (3) the adoption of any plan or proposal for the
               liquidation or dissolution of the Company;

              (b) At any time during a period of two consecutive years,
individuals who at the beginning of such period constituted the board of
directors of the Company ("Incumbent Directors") shall cease for any reason to
constitute at least a majority thereof; provided, however, that the term
"Incumbent Director" shall also include each new director elected during such
two-year period whose nomination or election was approved by two-thirds of the
Incumbent Directors then in office; or

               (c) Any person (as such term is used in Section 14(d) of the
Securities Exchange Act of 1934, other than the Company or any employee benefit
plan sponsored by the Company) shall, as a result of a tender or exchange offer,
open market purchases or privately negotiated purchases from anyone other than
the Company, have become the beneficial owner (within the meaning of Rule 13d-3
under the Securities Exchange Act of 1934), directly or indirectly, of
securities of the Company ordinarily having the right to vote for the election
of directors ("Voting Securities") representing twenty percent (20%) or more of
the combined voting power of the then outstanding Voting Securities.

9. Amendment and Termination of the Plan.
   --------------------------------------

     (1) AMENDMENT. The Board may at any time amend the Plan in whole or in
part; provided, however, that no amendment shall decrease or restrict the amount
credited to any Account maintained under the Plan as of the date of amendment.
An amendment affecting the interest rate credited under Paragraph 4 shall not
become effective before the first day of the calendar year which follows the
adoption of the amendment and at least 30 days written notice of the amendment
to the Director.

     (2) TERMINATION. The Board may at any time partially or completely
terminate the Plan if, in its judgment, the tax, accounting, or other effects of
the continuance of the Plan, or potential payments thereunder, would not be in
the best interests of the Company.

     (1) PARTIAL TERMINATION. The Board may partially terminate the Plan by
instructing the Committee not to accept any additional deferrals. In the event
of such a partial termination, the Plan shall continue to operate and be
effective with regard to deferrals entered into prior to the effective date of
such partial termination.

     (2) COMPLETE TERMINATION. The Board may completely terminate the Plan by
instructing the Committee not to accept any additional deferrals, and terminate
all ongoing deferrals. In the event of such a complete termination, the Plan
shall cease to operate and the Committee shall pay out to each Director the
balance in each of his or her Accounts in equal annual installments amortized
over the period listed below based on the balance in the particular Account at
the time of such complete termination:

                  Appropriate Account Balance               Payout Period
                  ------------------------------            -------------
                  Less than $10,000                           2 Years
                  $10,000 but less than $50,000               5 Years
                  More than $50,000                           10 Years

         Interest earned on the unpaid balance in a Director's Cash Account
shall be the applicable interest rate at the end of the calendar quarter
immediately preceding the effective date of such complete termination.

10.      Miscellaneous.
         --------------

     (1) UNSECURED GENERAL CREDITOR. The Accounts shall be established solely
for the purpose of measuring the amounts owed to a Director or beneficiary under
the Plan. Directors and their beneficiaries, heirs, successors and assigns shall
have no legal or equitable rights, interest or claims in any property or assets
of the Company, nor shall they be beneficiaries of, or have any rights, claims
or interests in any life insurance policies, annuity contracts or the proceeds
therefrom owned or which may be acquired by the Company. Except as may be
provided in Paragraph 10(b), such policies, annuity contracts or other assets of
the Company shall not be held under any trust for the benefit of the Directors,
their beneficiaries, heirs, successors or assigns, or held in any way as
collateral security for the fulfilling of the obligations of the Company under
this Plan. Any and all of the Company's assets and policies shall be, and
remain, the general, unpledged, unrestricted assets of the Company. The
Company's obligation under the Plan shall be that of an unfunded and unsecured
promise to pay money in the future.

     (2) TRUST FUND. The Company shall be responsible for the payment of all
benefits provided under the Plan. At its discretion, the Company may establish
one or more trusts, with such trustees as the Board may approve, for the purpose
of providing for the payment of such benefits. Such trust or trusts may be
irrevocable, but the assets thereof shall be subject to the claims of the
Company's creditors. To the extent any benefits provided under the Plan are
actually paid from any such trust, the Company shall have no further obligation
with respect thereto, but to the extent not so paid, such benefits shall remain
the obligation of, and shall be paid by, the Company.

     (3) NONASSIGNABILITY. No assignment or alienation may be made of any
deferred fees or interest thereon, except in accordance with Paragraph 6.

     (4) GOVERNING LAW. The provisions of this Plan shall be construed and
interpreted according to the laws of the State of Oregon.

     (5) SUCCESSORS. The provisions of this Plan shall bind and inure to the
benefit of the Company and its successors and assigns. The term successors as
used herein shall include any corporate or other business entity which shall,
whether by merger, consolidation, purchase or otherwise acquire all or
substantially all of the business and assets of the Company, and successors of
any such corporation or other business entity.

         The foregoing restatement of the Plan was approved by the Board of
Directors of Northwest Natural Gas Company on December 18, 1997.

                                      NORTHWEST NATURAL GAS COMPANY

                                      By:  /s/ Richard G. Reiten
                                          -------------------------


Attest:           /s/ C. J. Rue



                                                                 (Exhibit 10i.)

                          NORTHWEST NATURAL GAS COMPANY
                 NON-EMPLOYEE DIRECTORS STOCK COMPENSATION PLAN

                                 January 1, 1989

Northwest Natural Gas Company
  an Oregon corporation

220 NW Second Avenue

Portland, OR  97209                                                the Company

         The Company believes it desirable that members of its board of
directors, who represent the Company's shareholders, be themselves shareholders.
To supplement the efforts of the directors towards this end, the Company wishes
to increase the ownership interest of non-employee directors through awards of
Company Common Stock. The Company expects by this means to increase the
community of interest of its shareholders at large and the Company's directors
and to make stock ownership a dynamic influence on the attitudes of its board of
directors.

         The following plan is therefore adopted:

         1.       Administration.
                  ---------------

         Unless otherwise determined pursuant to this section, this plan shall
be administered by the corporate secretary of the Company (the Administrator),
who may delegate all or part of that authority and responsibility. The
Administrator shall interpret the plan, arrange for the purchase and delivery of
shares, determine forfeitures, and otherwise assume general responsibility for
administration of the plan. Any decision by the Administrator shall be final and
bind all parties. The Administrator may be replaced from time to time in the
discretion of the chief executive officer of the Company.

         2.       Awards.
                  -------

                  2.1 Each non-employee director of the Company, including those
directors who have been employees of the Company in the past but are not
employees at the time of any award under this plan, shall be awarded Common
Stock of the Company as of the following award dates:

                    (a)  January 1, 1989; or

                    (b) In the case of (i) directors elected after January 1,
1989 and (ii) persons who become non-employee directors after January 1, 1989 by
ceasing to be employees of the Company, the date on which such director is first
elected, whether by the shareholders or board of directors of the Company, or
ceases to be an employee of the Company, as the case may be; and

                    (c) On January 1 of each year thereafter, commencing with
January 1, 1998.

                  2.2 As of each award date, a participant shall receive an
award calculated in the following manner. The "Number of Award Months" shall be
determined by subtracting the number of month ends remaining until all, if any,
previous awards to the participant under this plan will be vested from the
number of month ends remaining until the fifth year end after the award date;
provided, however, that if, assuming the participant were reelected, a
participant's term as a director would end because of age before the fifth year
end after the award date, the "Number of Award Months" shall be determined by
subtracting the number of month ends remaining until all, if any, previous
awards to the participant under this plan will be vested from the number of
month ends remaining until the participant's term will end because of age. The
amount awarded shall then be calculated by multiplying the Number of Award
Months by $833.33.

                  2.3 As of each award date, the dollar amount calculated under
2.2 shall be awarded to the participant in Common Stock as follows:

                    (a) As soon as practicable after the award date, the
Administrator shall deliver cash in the amount of the award and applicable
commissions to one or more brokers or other persons with instructions to
purchase Company Common Stock in the open market. It is understood that market
conditions or regulations affecting the purchases by a corporation of its own
shares may extend the period of purchase over several days or weeks.

                    (b) When several participants have the same award date, all
of the stock shall be purchased and then divided among the participants in
proportion to their respective awards, regardless of any changes in price that
occur while purchases are being carried out.

                    (c) When all of the stock has been purchased with respect to
any award date, certificates in the names of the participants for their
respective shares shall be delivered to the Administrator. Each participant
shall deliver to the Administrator a blank stock power duly executed in a form
satisfactory to the Administrator for each certificate for shares issued in the
participant's name.

                    (d) The Administrator shall hold the certificates and stock
powers until the shares are vested and released as provided in 3.4.

               2.4 Upon any amendment of this plan to increase the dollar amount
of awards set forth in 2.2, each participant shall receive an additional award
in accordance with the procedures set forth in 2.3. The amount of the additional
award for each participant shall be determined by multiplying the amount of the
increase in the award amount by the number of month ends remaining until the
participant's most recent prior award under this plan will be fully vested. The
resulting dollar amount shall then be used to purchase Common Stock for the
participant as set forth in 2.3.

         3.    Vesting; Delivery of Shares; Forfeitures.
               -----------------------------------------

               3.1 For each award under 2.2 and 2.3, the number of awarded
shares that will vest per month shall be determined by dividing the number of
awarded shares by the Number of Award Months. This monthly amount shall vest as
of the last day of each calendar month commencing with the later of the month in
which the award is made or the first month after all previous awards to the
participant under this plan shall have vested.

               3.2 For each award under 2.3 and 2.4, the number of awarded
shares that will vest per month shall be determined by dividing the number of
awarded shares by the number of month ends remaining until the participant's
most recent prior award under 2.2 and 2.3 will be fully vested. This monthly
amount shall vest as of the last day of each calendar month commencing with the
month in which the award is made.

               3.3 Notwithstanding 3.1 and 3.2, all awarded shares shall vest
upon a change in control of the Company. For purposes of this plan, a "change in
control" of the Company shall mean the occurrence of any of the following
events:

                    (a)  The approval by the shareholders of the Company of:

                         (1) any consolidation, merger or plan of share exchange
     involving the Company (a "Merger") in which the Company is not the
     continuing or surviving corporation or pursuant to which shares of Common
     Stock would be converted into cash, securities or other property, other
     than a Merger involving shares of Common Stock in which the holders of
     shares of Common Stock immediately prior to the Merger have the same
     proportionate ownership of common stock of the surviving corporation
     immediately after the Merger;

                          (2) any sale, lease, exchange or other transfer (in

     one transaction or a series of related transactions) of all, or
     substantially all, the assets of the Company; or

                          (3) the adoption of any plan or proposal for the
     liquidation or dissolution of the Company;

                     (b) At any time during a period of two consecutive years,
individuals who at the beginning of such period constituted the board of
directors of the Company ("Incumbent Directors") shall cease for any reason to
constitute at least a majority thereof; provided, however, that the term
"Incumbent Director" shall also include each new director elected during such
two-year period whose nomination or election was approved by two-thirds of the
Incumbent Directors then in office; or

                     (c) Any person (as such term is used in Section  14(d) of
the Securities Exchange Act of 1934, other than the Company or any employee
benefit plan sponsored by the Company) shall, as a result of a tender or
exchange offer, open market purchases or privately negotiated purchases from
anyone other than the Company, have become the beneficial owner (within the
meaning of Rule 13d-3 under the Securities Exchange Act of 1934), directly or
indirectly, of securities of the Company ordinarily having the right to vote for
the election of directors ("Voting Securities") representing twenty percent
(20%) or more of the combined voting power of the then outstanding Voting
Securities.

                  3.4 The certificate and stock power for vested shares shall be
delivered to the participant or in accordance with 5.2 as soon as practicable
after the participant ceases to be a director of the Company or, if earlier, as
soon as practicable after a change in control of the Company.

                  3.5 If a participant ceases to be a director (other than
pursuant to a simultaneous change in control of the Company), awarded shares
remaining unvested shall be forfeited. The Administrator, acting for the
participant pursuant to the executed stock power, shall transfer the unvested
shares to the Company, and these shares shall be cancelled. The participant or
the participant's representative shall execute any documents reasonably
requested by the Administrator to facilitate the transfer.

         4.       Status Before Full Vesting; Transfer of Shares.
                  -----------------------------------------------

                  4.1 Each participant shall be a shareholder of record with
respect to all shares awarded, whether or not vested, and shall be entitled to
all of the rights of such a holder, except that a participant's share
certificates shall be held by the Administrator until delivered in accordance
with 3.4.

                  4.2 Any dividends or communications to shareholders received
by the Administrator with respect to shares held by the Administrator shall
promptly be transmitted to the participant.

                  4.3 No participant may transfer any interest in unvested
shares to any person other than the Company.

                  4.4 No participant may transfer any interest in any shares
awarded under this plan, whether vested or not, until he or she ceases to be a
director of the Company.

                  4.5 Notwithstanding 2.3(d), 3.4, 4.1, 4.3 and 4.4, if a
participant in the Company's Directors Deferred Compensation Plan (the "DDCP")
elects under the DDCP to defer shares of Company Common Stock awarded to the
participant under this plan, promptly after the deferral election becomes
irrevocable the Administrator shall cause the Common Stock subject to such
irrevocable deferral to be transferred to the trustee of the Northwest Natural
Gas Company Umbrella Trust(TM) For Directors. The Common Stock so transferred
shall nevertheless remain subject to forfeiture under 3.5 if the participant
ceases to be a director prior to vesting of the shares.

         5. Death of a Participant.
            -----------------------

                  5.1 Any vested shares held by the Administrator for a
participant who has died shall be delivered as soon as practicable to the
participant's death beneficiary under 5.2.

                  5.2 Any vested shares to be delivered on death of a
participant under 5.1 shall go to a participant's beneficiary in the following
order of priority:

                           (a) To the surviving beneficiary designated by

Paragraph 5.1 of the Employment Agreement between the undersigned parties dated

replaced by the following, to conform to the original intent of the parties:

5.1       ...Company's Retirement Plan without any reduction based on age at

          select any of the benefit payment options under Section 3.01 of the
          ESRIP for which he is eligible.

5.2       Full ESRIP. NNG shall be liable under the ESRIP to pay Dodson the full
          ESRIP benefit using the 65 percent normal retirement income target
          provided under Section 2.01-1(b) of the ESRIP once any of the

               completes the Second Term;

               during employment by NNG;

          (c)  NNG terminates Dodson without cause, where "cause" has the
               meaning set forth in paragraph 4(iii) of Dodson's separate
               severance agreement dated September 15, 1997; or

          (d)  Dodson becomes entitled to receive severance benefits for
               termination of employment in connection with a change of control,
               where such entitlement is determined under the provisions of
               Dodson's separate severance agreement dated September 15, 1997.

5.3  One-half ESRIP. At the end of the initial Term, or at any time thereafter
     prior to completing the Second Term, NNG shall be liable under the ESRIP to
     pay Dodson a one-half ESRIP benefit using a 32.5 percent normal retirement
     income target under ESRIP Section 2.01-1(b) in place of the 65 percent
     target if Dodson terminates employment with NNG under circumstances where
     he is not entitled to full ESRIP benefits under 5.2 above.
