                          NORTHWEST NATURAL GAS COMPANY
                          PART I. FINANCIAL INFORMATION
                 (5) NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


1.   Basis of financial statements

     The information presented in the consolidated financial statements is
unaudited, but includes all adjustments, consisting of only normal recurring
accruals, which the management of the Company considers necessary for a fair
presentation of the results of such periods. These consolidated financial
statements should be read in conjunction with the financial statements and
related notes included in the Company's 1998 Annual Report on Form 10-K (1998
Form 10-K). A significant part of the business of the Company is of a seasonal
nature; therefore, results of operations for the interim periods are not
necessarily indicative of the results for a full year.

     Certain amounts from prior periods have been reclassified to conform with
the 1999 presentation.

2.   Recently Issued Accounting Standards

     In June 1998, the Financial Accounting Standards Board (FASB) issued
Statement of Financial Accounting Standards (SFAS) No. 133, "Accounting for
Derivative Financial Instruments and Hedging Activities." This standard is
effective for all fiscal years beginning after June 15, 1999 (January 1, 2000
for the Company). SFAS No. 133 requires that all derivative instruments be
recorded each period either in current earnings or in other comprehensive
income, depending on whether a derivative is designated as part of a hedge
transaction and, if so designated, what type of hedge transaction it is. The
Company has not determined the impact that adoption of SFAS No. 133 will have on
results of operation or its financial position.

     The FASB's Emerging Issues Task Force (EITF) Issue 98-10, "Accounting for
Energy Trading and Risk Management Activities," which is effective for fiscal
years beginning after December 15, 1998, addresses how to account for purchases
and sales of energy trading contracts. The Company's purchase and sales
activities do not meet the definition of trading activities, and therefore EITF
Issue 98-10 is not applicable.

     The American Institute of Certified Public Accountants' Accounting
Standards Executive Committee issued Statement of Position (SOP) 98-1,
"Accounting for the Costs of Computer Software Developed or Obtained for
Internal Use," and SOP 98-5, "Reporting on the Costs of Start-Up Activities,"
which are effective for years beginning after December 31, 1998. The Company has
adopted SOP 98-1 and SOP 98-5 with no material effect on the results of
operations or financial position.

3.   Segment Reporting

     The Company principally operates in a single line of business consisting of
the distribution of natural gas. Other segments are primarily investments in oil
and gas exploration properties in Canada and in alternative energy projects in
California.

     The following table presents information about reportable segments for the
three months ended March 31, 1999 and 1998. Inter-segment transactions are
insignificant.

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

          Earnings from consolidated operations were 93 cents a diluted share
for the quarter ended March 31, 1999, compared to 97 cents a diluted share in
last year's first quarter. The Company's earnings applicable to common stock
were $23.4 million in the quarter ended March 31, 1999, up 4 percent from
$22.5 million in the first quarter of 1998.

          NW Natural earned 95 cents a diluted share from utility operations in
the first quarter of 1999, compared to 85 cents a diluted share in the same
period in 1998. Weather conditions in NW Natural's service territory in the
first quarter of 1999 were 9 percent colder than the first quarter of 1998 and
comparable to normal weather conditions. The Company estimates that the
weather-related increase in gross margin revenues (margin) during the first
quarter of 1999 was equivalent to about 18 cents a share compared to the first
quarter of 1998. Weather conditions in the first quarter of 1998 were 8 percent
warmer than average resulting in an estimated margin reduction equivalent to
22 cents a share as compared to the first quarter of 1997. These estimates are
derived from the Company's internal planning model (see Part II, Item 7.,
"Earnings and Dividends," in the 1998 Form 10-K). The model also estimates that
customer growth in the residential and commercial segments since March 31, 1998
contributed an additional $3.9 million of margin during the first quarter of
1999.

          NW Natural's subsidiaries lost 2 cents a share during the first
quarter of 1999, compared to a loss of 3 cents in the first quarter of 1998. See
"Subsidiary Operations."

          Dividends paid on common stock were 30.5 cents a share for each of the
three-month periods ended March 31, 1999 and 1998. In April 1999, the Company's
Board of Directors declared a quarterly dividend of 30.5 cents a share on its
common stock, payable May 14, 1999, to shareholders of record on April 30, 1999.
The current indicated annual dividend rate is $1.22 a share.

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

          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 these customers. Average weather conditions
are calculated from the most recent 20 years of temperature data measured by
heating degree days. Weather conditions were comparable to average conditions in
the first quarter of 1999 and 9 percent colder than in the first quarter of
1998.

          NW Natural continues to experience a high level of customer growth
relative to other local gas distribution companies, with 23,812 customers added
since March 31, 1998 for a growth rate of 5.2 percent. In the three years ended
Dec. 31, 1998, more than 67,000 customers were added to the system, representing
an average annual growth rate of 5.2 percent.

          Volumes of gas sold to residential and commercial customers increased
36.7 million therms, or 18 percent, in the first quarter of 1999 compared to the
first quarter of 1998. Related revenues increased $33.7 million, or 30 percent,
due to increased volumes and rate increases effective during 1998. Effective
Jan. 1, April 1 and Dec. 1, 1998, the OPUC approved rate increases averaging
11.4 percent, 6.1 percent and 3.4 percent, respectively, for NW Natural's

                                   11

<PAGE>


customers in Oregon. These rate changes 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 in 1997. Effective Dec. 1, 1998, the WUTC approved a rate increase
averaging 5.8 percent primarily to pass through to Washington customers
increases in purchased gas costs.

         In October 1998, NW Natural filed its first general rate case in
Oregon since 1989. The filing proposes a revenue increase of $14.7 million per
year from Oregon operations through rate increases averaging 3.8 percent. The
proposed increase is designed to cover the costs of additional gas storage at
Mist, NW Natural's new customer information system, and the Year 2000 project.
In November 1998, the OPUC suspended the proposed rate increase for
investigation and hearings. In March 1999, the Staff of the OPUC issued its
recommendations on issues in the general rate case. The Staff recommended a
revenue reduction of $19.9 million per year which incorporates a recommended
return on common shareholders' equity (ROE) of 8.5 percent, compared to NW
Natural's proposed ROE of 11.25 percent. NW Natural's currently authorized ROE
is 13.25 percent. The OPUC Staff is considered to be an independent party in the
rate case. Its position is not binding on either the administrative law judge
who will preside over hearings in the case or on the Commission when it makes
its decisions on the issues. The OPUC is expected to extend its order suspending
the filing for investigation and hearing until Sept. 1, 1999.

          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
              ---------------------------------------------------

         Total volumes delivered to industrial firm, industrial interruptible,
and transportation customers were 13.8 million therms, or 8 percent, lower in
the first quarter of 1999 than in the same period of 1998. Margin from these
customers decreased by 8 percent to $12.6 million in the first quarter of 1999
from $13.7 million in the first quarter of 1998, reflecting some large
interruptible customers' use of oil rather than gas during the quarter, lower
margins from industrial schedules where rates are tied to oil prices, and the
loss of one industrial customer to bypass. (See Part II, Item 7., "Results of
Operations - Industrial Sales, Transportation and Other Revenues," in the 1998
Form 10-K.)

          Other revenues, which relate primarily to accumulations or
amortizations of regulatory accounts (see Part II, Item 8., Note 1, "Notes to
Consolidated Financial Statements," in the 1998 Form 10-K), decreased $1.1
million, or 83 percent, during the first quarter of 1999 compared to the first
quarter of 1998. The principal factors were a decrease in amortizations of
property tax savings ($2.6 million), offset by the conclusion of amortizations
of revenue reductions negotiated with the OPUC as part of the Jan. 1, 1998 rate
change ($0.8 million) and the refund of 1996-97 excise taxes ($0.4 million).

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

          The cost per therm of gas sold was 23 percent higher during the first
quarter of 1999 than in the first quarter of 1998. The cost per therm of gas
sold includes current gas purchases, gas drawn from storage, demand cost
equalization and regulatory deferrals, less Company use. The cost of gas sold 
was reduced by non-regulated net gas sales of $0.4 million and $0.8 million for
the first quarters of 1999 and 1998, respectively. Under an agreement with the 
OPUC,

                                   12

<PAGE>

revenues from these sales are treated as a reduction of gas costs.

          The average cost per therm of gas purchased in the first quarter of
1999 was 7 percent higher than in the first three months of 1998, due to higher
prevailing prices in the natural gas commodity market. NW Natural has a
Purchased Gas Adjustment (PGA) tariff in Oregon, under which its net income from
Oregon operations is affected only within defined limits by changes in purchased
gas costs. Effective Jan. 1, 1998, NW Natural recognizes 33 percent of the
difference between actual and projected gas costs in current operating results
while the remaining 67 percent is deferred for recovery from or refund to
customers in future rates. (See Part II, Item 5, Other Information, "Regulatory
Developments.")

         Results of operations for the individual subsidiaries for the first
quarter of 1999 were a net loss of $0.1 million for Canor compared to a
negligible net loss for the first quarter of 1998, and a net loss of
$0.3 million for Financial Corporation compared to a net loss of $0.7 million
for the first quarter of 1998. Canor's operations have been adversely affected
by low oil prices during the first quarter of 1999, while Financial Corporation
normally incurs a loss in the first quarter due to the seasonality of revenues
from its investments in solar and windpower generating plants in California.

         In the first quarter of 1998 NW Natural recorded a $3.5 million gain,
equivalent to 15 cents a share, from the combination of Canor with Southlake
Energy, Inc. (Southlake), an indirect subsidiary of NIPSCO Industries, Inc.
Canor purchased Southlake's stock in exchange for shares of Canor, with the
resulting company owned 66 percent by NW Natural and 34 percent by an indirect
subsidiary of NIPSCO. The resulting gain was not subject to U.S. income tax.
Canor had managed Southlake's assets since 1995 under a previous agreement.

         The following discussion summarizes operating expenses, other income
(expense), interest charges - net, and income taxes.

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

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

         Operations and maintenance expenses were $2.3 million, or 11 percent,
higher in the first quarter of 1999 compared to the same period in 1998. NW
Natural's expenses increased $1.6 million, or 8 percent, in the first quarter of
1999, primarily due to costs of a special voluntary early retirement program
($0.8 million) and higher accruals for bad debts ($0.6 million). Subsidiary
operating expenses increased $0.7 million, or 59 percent, as compared to the
first quarter of 1998, due to the inclusion in this category of expenses of
Southlake following the Canor/Southlake amalgamation at the end of the first
quarter of 1998.

         Taxes Other than Income
         -----------------------

         Taxes other than income increased $1.4 million, or 20 percent.
Franchise tax expense increased $0.9 million in the first quarter of 1999
compared to the first quarter of 1998 as a result of the higher revenues
reflecting rate increases and increased sales due to colder weather. Property
taxes increased $0.3 million due to more utility plant in service, while
regulatory commission fees and local business taxes each increased $0.1 million.

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

         The Company's depreciation expense increased $1.6 million, or
13 percent, compared to the first quarter of 1998. NW Natural's depreciation
expense increased by $0.4 million primarily due to the placement into service in
November 1998 of an expansion of its underground gas storage facility (Mist
Phase II) ($0.3 million) and other additional utility plant. Subsidiary
depreciation expense increased $1.2 million in the first quarter of 1999
compared to 1998 due to an increase in Canor's total assets following its
amalgamation with Southlake.

    Other Income (Expense)
    ----------------------

         The Company's other income decreased $1.6 million in the first quarter
of 1999 compared to the same period in 1998. Results from the first quarter of
1998 included the one-time $3.5 million gain from the combination of Canor with
Southlake (see "Subsidiary Operations," above). The first quarter of 1999
included a gain on the sale of assets by Canor ($0.6 million); a smaller loss
from Financial Corporation's alternative energy investments ($0.6 million); an
increase in net income from merchandise sales ($0.4 million); and increased
interest income ($0.1 million).

    Interest Charges - net
    ----------------------

         The Company's net interest expense decreased $0.2 million, or
3 percent, in the first quarter of 1999 compared to the same period in 1998.
Long-term debt decreased $3.5 million from March 31, 1998 and average interest
rates on outstanding debt declined due to the redemption or maturity of
$33.0 million of long-term debt bearing interest rates of 8.93 percent to
9.125 percent in the second and third quarters of 1998.

          The effective corporate income tax rates for the three months ended
March 31, 1999 and 1998 were 37 percent and 31 percent, respectively. The lower
1998 rate was due in part to the $3.5 million gain from the Canor combination
with Southlake that was not subject to income tax. (See Part II, Item 8.,
Note 7, "Notes to Consolidated Financial Statements," in the 1998 Form 10-K).

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

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

         NW Natural's capital expenditures are primarily related to 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 revenue derived from gas usage by NW Natural's
residential and commercial customers influences the Company's financing
requirements from one quarter to the next. Short-term liquidity is satisfied
primarily through the sale of commercial paper, which is supported by commercial
bank lines of credit (see Part II, Item 8., Note 6, "Notes to Consolidated
Financial Statements," in the 1998 Form 10-K).

          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 stock
redemption requirements (see Part II, Item 8., Notes 3 and 5, "Notes to
Consolidated Financial Statements," in the 1998 Form 10-K).

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

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

         Operating activities provided net cash of $72.4 million in the three
months ended March 31, 1999 compared to $43.1 million in the first three months
of 1998. The 68 percent increase was due to increased cash from operations
($7.2 million) and lower working capital requirements ($22.2 million). The
increase in cash from operations compared to 1998 was primarily due to lower
deferred gas costs receivable ($11.2 million), a decrease in non-cash gains on
the sale of assets ($2.7 million) and an increase in depreciation, depletion and
amortization expense ($1.6 million); offset by a reduction in deferred income
taxes and investment tax credits ($3.3 million) and higher regulatory account
debit balances ($5.1 million). The decrease in working capital requirements was
due to greater decreases in accrued unbilled revenue ($6.4 million) and
inventory balances ($5.6 million), a smaller decrease in accounts payable
($5.3 million) and a greater increase in accrued interest and taxes
($5.1 million). A non-cash gain of $3.5 million was recognized in the first
quarter of 1998 from Canor's amalgamation with Southlake.

         The Company has lease and purchase commitments relating to its
operating activities which are financed with cash flows from operations (see
Part II, Item 8., Note 12, "Notes to Consolidated Financial Statements," in the
1998 Form 10-K).


                                   15

<PAGE>

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

          Cash requirements for utility construction in the first quarter of
1999 totaled $25.4 million, up $5.1 million, or 25 percent, from the first
quarter of 1998. The increase was primarily due to higher expenditures for the
development of additional underground storage facilities ($4.6 million).

          NW Natural's construction expenditures are estimated at $110 million
for 1999. Over the five year period 1999 through 2003, these expenditures are
estimated at between $450 million and $500 million. The projected level of
capital expenditures during the next five years reflects projected customer
growth, a major system reinforcement project and the development of additional
underground storage facilities. It is anticipated that approximately 50 percent
of the funds required for these expenditures will be internally generated, and
that the remainder will be funded through the sale of long-term debt and equity
securities with short-term debt providing liquidity and bridge financing.

          In the first quarter of 1999, non-utility expenditures totaled
$4.6 million. Canor invested $2.1 million in Canadian exploration and production
properties and NW Natural's non-utility expenditures were $2.5 million for the
construction of the Port of Portland building (see "Lines of Credit," below).
During the first quarter of 1998, NW Natural converted to equity $11.8 million
of intercompany loans to Canor. (See Part II, Item 7., Financial Condition,
"Investing Activities," in the 1998 Form 10-K.)

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

                  In the first quarter of 1999, internally generated cash was
used to reduce short-term debt by $36.0 million. In the first quarter of 1998,
proceeds from the issuance of Medium-Term Notes were used to reduce short term
debt by $12.5 million and long-term debt by $2.0 million.

    Lines of Credit
    ---------------

         NW Natural has available through Sept. 30, 1999, 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 Sept. 30, 1999, committed lines of credit with two commercial
banks totaling $20 million, consisting of a primary fixed amount of $15 million
plus an excess amount of up to $5 million available as needed, at Financial
Corporation's option, on a monthly basis. Financial Corporation's lines are
supported by the guaranty of NW Natural.

          Under the terms of these lines of credit, which are used as backup
lines for commercial paper programs, NW Natural and Financial 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. There were no outstanding balances on either the NW
Natural or Financial Corporation lines of credit as of March 31, 1999 or 1998.

          In April 1998, NW Natural entered into an additional $18 million line
of credit with a commercial bank for the purpose of constructing the new
headquarters building for the Port of Portland on land currently owned by NW
Natural (see "Investing Activities," above). This line of credit is available
through Nov. 30, 1999, and the outstanding balance at March 31, 1999 was
$8.6 million.


                                   16

<PAGE>

          Canor has a $30 million (Canadian) revolving credit facility available
for its normal business operations through a Canadian commercial bank. The
amount of the facility declines by $1.2 million per quarter beginning April 1,
1999 and is subject to a re-setting annually either upward or downward, based
upon an analysis of Canor's gas and oil reserves as of March 31 each year. Canor
had the U.S. dollar equivalent of $4.8 million outstanding on this line of 
credit at March 31, 1999.

    Commercial Paper
    ----------------

          The Company's primary source of short-term funds is commercial paper.
Both NW Natural and Financial Corporation issue commercial paper under agency
agreements with a commercial bank. Financial Corporation's commercial paper is
supported by the guaranty of NW Natural (see Part II, Item 8., Note 6, "Notes to
Consolidated Financial Statements," in the 1998 Form 10-K).

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

          For the 12 months ended March 31, 1999 and Dec. 31, 1998, the
Company's ratios of earnings to fixed charges, computed using the Securities and
Exchange Commission method, were 2.26 and 2.12, respectively. For this purpose,
earnings consist of net income before taxes plus fixed charges. 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
- ----------------------

    Year 2000 Readiness
    -------------------

              Overview
              --------

         The Company has identified and is in the process of correcting the
information technology (IT) and non-IT systems within its control that could be
affected by the Year 2000 issue. In early 1997, NW Natural established a Year
2000 Project Office with technical specialists experienced in the Year 2000
issue, sponsored by two senior executives.

         The Company's objective in its Year 2000 program is to reduce the risk
of business disruption or serious financial loss due to IT and non-IT systems
failures relating to the Year 2000 issue. In November 1997, NW Natural replaced
its largest operating system, its customer information system for residential
and small commercial customers incorporating billing, customer order, credit and
other programs, with a fully Year 2000-ready system. Additional project work
includes maintaining and managing the inventory of its date-sensitive IT and
non-IT systems; researching and managing the degree of Year 2000 readiness of IT
and non-IT systems of the suppliers and vendors with whom it has material
relationships; identifying and assessing the cost of renovating or replacing
non-IT systems within its control that could be affected by the Year 2000 issue;
assigning risk ratings to its IT and non-IT systems in order to prioritize
renovation and replacement efforts; and developing contingency plans for
high-risk systems or vendor products where products are known to be
non-compliant or readiness levels cannot be independently verified.


                                    17

<PAGE>


              Readiness of Systems
              --------------------

         The Year 2000 project office has achieved various stages of correction
for impacted IT systems and non-IT equipment and, overall, NW Natural has
maintained and expects to continue its planned schedule for correction. NW
Natural plans to complete renovations of its internal applications with the
highest risk ratings by June 30, 1999, and to evaluate and develop appropriate
plans to renovate or address risks of failure in its remaining lower-risk
systems by the end of 1999.

         Among 29 high-priority applications originally identified for internal
renovation, 38 percent had been completed through construction, testing and
implementation as of March 31, 1999.

         NW Natural has been developing a new billing system for industrial and
large commercial (I&C) customers to replace an existing system that is not Year
2000 compliant. The development project for the new I&C system is on schedule,
but NW Natural has implemented a contingency plan for the renovation of the
existing system so that it could be ready by year-end. This effort may be
terminated at any time if it appears that the I&C replacement project is
reaching its key milestones on schedule for completion by October 1999.

              Suppliers and Vendors
              ---------------------

         NW Natural is evaluating the status of Year 2000 compliance efforts of
critical suppliers and vendors. These contacts include written communication or
face-to-face meetings with providers of interstate capacity and storage, natural
gas suppliers, financial institutions and electric and telephone companies. In
addition, the project office is currently investigating 588 vendor-supplied
products. Of these products, as of March 31, 1999, 443 products either have been
determined to be compliant or have been represented by the vendors to be
compliant if used in connection with other compliant systems. Another 89
products were deemed non-compliant and 56 products were under active
investigation. If warranted, the Company will identify alternative vendor
sources to the extent alternatives are available, and develop contingency plans
for any critical vendor products considered at risk where alternatives are not
available.

              Risks and Contingency Planning
              ------------------------------

          The Company has not quantified its worst-case exposure from the Year
2000 issue, but the project office intends to make such estimates while
prioritizing the highest-risk systems for correction.

          With respect to its internal operations, NW Natural believes its most
significant risks are its ability to render timely bills to its industrial and
large commercial customers, its ability to use electronic devices to control and
operate its distribution system and its ability to maintain continuous operation
of its computer systems. In the event that any Year 2000-related problems may
occur, the Company intends to implement contingency plans to mitigate the impact
of such failures to the extent possible. These plans will include options for
manual control and operation of the gas distribution system.

         With respect to external factors, NW Natural relies on the suppliers
of natural gas and interstate transportation to deliver natural gas to NW
Natural's distribution system. External infrastructure such as electric and
telephone service is necessary for NW Natural's basic operation as well as the

                                   18

<PAGE>

operations of many of its customers. A failure by any of these critical vendors
could challenge NW Natural's ability to meet the demands of its customers. As
part of its normal business practice, however, NW Natural maintains plans to
follow during emergency circumstances. These plans are incorporated into its
contingency plan for potential Year 2000-related problems.

              Financial Impact
              ----------------
         NW Natural's total estimated cost for its Year 2000 readiness program
is $6.9 million. This amount includes its costs of assessment, planning, vendor
management, project management and other project costs as well as the costs of
renovating and testing internal applications. NW Natural's costs from 1997
through March 31, 1999 for Year 2000 activities totaled $4.9 million. Neither
the total estimated cost nor the costs to date include the costs incurred in
replacing NW Natural's customer information system or costs for other IT systems
that are being replaced rather than renovated. In accordance with an order of
the OPUC, NW Natural's incremental operating costs for Year 2000 readiness are
being deferred and will be amortized over a five-year period.

              Disclaimer
              ----------

         As a result of its Year 2000 program and the replacement of the
residential and small commercial customer information system, the Company does
not believe that, in the aggregate, Year 2000 issues will be material to its
business, operations or financial condition. However, despite the Company's
efforts, there can be no assurance that all material Year 2000 risks relating to
systems within its control will have been adequately identified and corrected
before the end of 1999. In addition, while the Company is in the process of
researching the Year 2000 readiness of its suppliers and vendors, the Company
can make no assurances regarding the Year 2000 compliance status of systems or
parties outside its control, and currently cannot assess the effect on it of any
non-compliance by such systems or parties.

         The Year 2000 statements in this report are Year 2000 Readiness
Disclosures under the Year 2000 Information and Readiness Disclosure Act and are
made to the best knowledge and belief of the Company.


Item 3.       QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

          There have been no material changes to the information provided in
Part II, Item 7A., "Quantitative and Qualitative Disclosures About Market Risk,"
in the 1998 Form 10-K.


                           PART II. OTHER INFORMATION

Item 5.       OTHER INFORMATION

              Regulatory Developments
              -----------------------

          On April 19, 1999 the OPUC issued its order addressing the future
treatment of NW Natural's purchased gas costs. In its order, the OPUC formalized
a process that tests for "excessive earnings" in connection with gas utilities'
annual PGA filings of rate changes due to increases or decreases in gas
commodity costs. Under the order, NW Natural is authorized to retain all of its
earnings up to a threshold level equal to its authorized return on equity plus
300 basis points. Until a decision is made on NW Natural's authorized ROE in the

                                   19

<PAGE>

pending Oregon general rate case (see Part I, Item 2., "Results of Operations"),
NW Natural can earn up to a 12.6 percent ROE. One-third of any "excess" above
that level will be refunded to customers. The OPUC order also confirmed NW
Natural's ability to pass through 100 percent of its prudently incurred gas
costs into rates.

              Gas Storage
              -----------

          On March 30, 1999, the Oregon Energy Facility Siting Council approved
NW Natural's application to amend its site certificate for the South Mist
Feeder, its pipeline connecting the Mist gas storage field with NW Natural's
distribution system in metropolitan Portland. The amendment authorizes
construction of 29 miles of 24-inch pipeline parallel to the original 16-inch
pipeline built in the late 1980s. The new pipeline, together with additional
underground storage reservoirs and gas compression capacity, will increase gas
deliverability from Mist to 190 million cubic feet per day, representing about
30 percent of NW Natural's firm gas load on its most recent peak day.

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

Incorporation. At each election of directors holders of shares of common stock
