                           PART II. OTHER INFORMATION



Item 5.   Other Events

         The following press release was issued by Northwest Natural Gas Company
on February 27, 1998:

         PORTLAND, Ore. - The Board of Directors of Northwest Natural Gas
Company (Nasdaq Stock Market: NWNG), dba NW Natural, has declared a quarterly
dividend of 30.5 cents a share on the Company's common stock, as well as regular
quarterly dividends on the Company's outstanding series of preferred and
preference stock.

         The following dividends will be paid May 15, 1998, to shareholders of
record on April 30, 1998:

         -  A regular quarterly dividend of $1.1875 per share on shares of the
            Preferred Stock $4.75 Series;

         -  A regular quarterly dividend of $1.78125 per share on shares of the
            Preferred Stock $7.125 Series;

         -  A regular quarterly dividend of $1.7375 per share on shares of the
            Preference Stock $6.95 Series; and

         -  A dividend of $0.305 per share on shares of the Common Stock.

         NW Natural also reported today that it estimates the warm weather in
this year's El Nino winter may reduce earnings for the quarter ending March 31,
1998, by 20 to 30 cents a share.

         Through Feb. 24, weather for the quarter has been about 15 percent
warmer than the 20-year average for that period. In the Company's service area,
January 1998 was the 7th warmest January in the past 25 years. If weather during
the remainder of the quarter were at average levels, the estimated net effect
for the quarter would be a reduction of about 20 cents a share. If the weather
continues at 15 percent warmer than average, however, the net effect for the
quarter would be closer to 30 cents a share.

         "This winter's El Nino pattern will leave a short-term earnings
disappointment in its wake," Bruce R. DeBolt, senior vice president and chief
financial officer, said Friday. "But it does not impair the Company's long-term
strengths, including our continuing story of profitable growth. NW Natural added
a record 24,900 new customers in 1997, and has grown at a rate of 5.4 percent
per year over the past three years."

         The Company's estimates of weather impact are derived from a model that
calculates expected revenues from sales to weather-sensitive customers as a
function of "heating degree days," meaning the difference between 65 degrees
Fahrenheit and the average of a day's high and low temperatures.

         NW Natural serves about 458,000 customers in western Oregon and
southwest Washington.

governmental policy and regulatory action, the competitive environment and
economic factors, as well as weather conditions. For a more complete description

Securities and Exchange Commission on Form 10-Q for the quarters ended Mar. 31,
