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 that are other than statements of historical
facts. The Company's expectations, beliefs and projections are expressed in good
faith and are believed 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, among others, that
could cause the actual results of the Company to differ materially from those
projected in such forward-looking statements: (i) prevailing state and federal
governmental policies and regulatory actions, including those of the Oregon
Public Utility Commission, the Washington Utilities and Transportation
Commission and the U.S. Department of Transportation's Office of Pipeline
Safety, 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, the maintenance
of pipeline integrity, present or prospective wholesale and retail competition,
changes in tax laws and policies and changes in and compliance with
environmental and safety laws, regulations and policies; (ii) weather conditions
and other natural phenomena; (iii) unanticipated population growth or decline,
and changes in market demand caused by changes in demographic or customer
consumption patterns; (iv) competition for retail and wholesale customers; (v)
pricing of natural gas relative to other energy sources; (vi) risks relating to
dependence on a single pipeline transportation provider for natural gas supply;
(vii) risks resulting from uninsured property damage to Company property,
intentional or otherwise; (viii) unanticipated changes in interest or foreign
currency exchange rates or in rates of inflation; (ix) economic factors that
could cause a severe downturn in certain key industries, thus affecting demand
for natural gas; (x) unanticipated changes in operating expenses and capital
expenditures; (xi) unanticipated changes in future liabilities relating to
employee benefit plans; (xii) capital market conditions, including their effect
on pension costs; (xiii) competition for new energy development opportunities;
(xiv) potential inability to obtain permits, rights of way, easements, leases or
other interests or other necessary authority to construct pipelines, develop
storage or complete other system expansions; and (xv) 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


                                       2



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.
