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 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, 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 and demographic patterns; (iv) competition for
retail and wholesale customers; (v) pricing of natural gas relative to other
energy sources; (vi) risks resulting from uninsured property damage to Company
property, intentional or otherwise; (vii) unanticipated changes in interest or
foreign currency exchange rates or in rates of inflation; (viii) economic
factors that could cause a severe downturn in certain key industries, thus
affecting demand for natural gas; (ix) unanticipated changes in operating
expenses and capital expenditures; (x) unanticipated changes in future
liabilities relating to employee benefit plans; (xi) capital market conditions,
including their effect on pension costs; (xii) competition for new energy

development opportunities; (xiii) potential inability to obtain permits, rights
of way, easements or other necessary authority to construct pipelines or other
system expansions; and (xiv) 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.
