(1) Pursuant to Rule 457, no registration fee separate from the registration fee
    for the Preferred Stock is required.
 
(2) Solely for the purpose of calculating the registration fee pursuant to Rule
    457(c) under the Securities Act of 1933, as amended ("Securities Act"), the
    proposed maximum offering price has been determined by multiplying (1) the
    average of the high and low prices for the Common Stock on August 11, 1998
    as reported in the consolidated reporting system for securities traded on
    the New York Stock Exchange by (2) a factor of ten, representing the number
    of shares of Common Stock which will be received by the Company in exchange
    for each share of Preferred Stock.
 
   
(3) The registration fee for the shares of the Preferred Stock registered hereby
    has been calculated pursuant to Rule 457(f)(1) under the Securities Act,
    which requires the registration fee to be based upon the market value of the
    Common Stock of The Washington Water Power Company (the "Company") to be
    received in exchange for the Preferred Stock. This registration fee was paid
    at the time of the initial filing of the Registration Statement on August
    17, 1998.
    
 
(4) Represents the number of shares of Common Stock issuable upon conversion of
    the Preferred Stock. Also being registered are such indeterminate number of
    additional shares of Common Stock as may be issuable upon or in connection
    with the conversion of the Preferred Stock as a consequence of the payment
    of any conversion premium or of adjustments to the Common Equivalent Rate
    (i.e. the rate at which shares of Preferred Stock are converted into shares
    of Common Stock).
 
(5) No additional consideration will be received by the Company upon conversion
    of the Preferred Stock and, therefore, pursuant to Rule 457(i) under the
    Securities Act, no separate registration fee is required.
 
   
(6) The Preferred Share Purchase Rights (the "Rights") are appurtenant to and
    will trade with the Common Stock.
    
 
   
(7) The value attributable to the Rights, if any, is reflected in the market
    price of the Common Stock. Because no additional consideration will be
    received by the Company upon conversion of the Preferred Stock and,
    therefore, pursuant to Rule 457(i) under the Securities Act, no separate
    registration fee is required.

                           EXCHANGE OFFER--IMPORTANT

    TO ENSURE TIMELY RECEIPT BY THE EXCHANGE AGENT, DO NOT MAIL OR PRESENT THE
LETTER OF TRANSMITTAL AND/OR STOCK CERTIFICATES TO THE COMPANY.
    
 
Dear Shareholder:
 
   
    On August 14, 1998, the Board of Directors approved an initiative that will
help position our Company to grow-- a Common Stock dividend restructuring plan.
We believe this change will better position us to pursue our growth strategies
and provide greater value for your investment in Washington Water Power. To
improve financial flexibility and retain a larger share of earnings in order to
fund future growth, the Board of Directors announced a plan to lower the annual
dividend paid to you, as a shareholder, from $1.24 to $0.48 per Common Share. We
also announced that we intend to change our corporate name to Avista Corporation
effective January 1, 1999. Our common stock will trade under the symbol "AVA."
    
 
    Recognizing that some of you may rely on current income from the dividend,
we have also created an opportunity for you to exchange your Common Shares for a
new security called RECONS(EDT) (Return Enhanced Convertible Securities).
 
    A RECONS is a security that:
 
    - will pay an annual dividend of $1.24 ($.31 each quarter);
 
    - will allow you to participate in future appreciation in the value of the
      Common Shares up to $[      ] per share;
 
    - will automatically convert into one Common Share on November 1, 2001,
      unless we choose to convert it earlier; and
 
   
    - we may convert, before its automatic conversion, into one or less than one
      Common Share, having a value up to a maximum of $[      ], plus all
      accrued and unpaid dividends, and on which, if converted before September
      15, 2001, we would also pay a premium, either in cash or Common Shares.
    
 
   
    For a more complete description of the terms of the RECONS, see "Description
of RECONS" beginning on page 26.
    
 
   
    Whether you should participate in the exchange offer depends on many
factors. FOR A DESCRIPTION OF RISK FACTORS ASSOCIATED WITH THE EXCHANGE OFFER,
SEE "RISK FACTORS/INVESTMENT CONSIDERATIONS" BEGINNING ON PAGE 12.
    
 
    We will accept a maximum of 20,000,000 Common Shares for exchange into
RECONS. You may tender all or part of your Common Shares, but if shareholders
tender more than 20,000,000 shares, we will accept tendered shares on a pro rata
basis. Fractional shares may not be tendered.
 
    This Exchange Offer is also subject to certain other conditions, including a
minimum tender of 6,000,000 Common Shares. THIS EXCHANGE OFFER WILL BE OPEN
UNTIL 12:00 MIDNIGHT, NEW YORK CITY TIME, ON     ,           , 1998, UNLESS WE
EXTEND IT. Until that time, you may tender your Common Shares or, if you have
tendered them and you change your mind, you may withdraw them by following the
procedures described in this document.
 
    To assist you in connection with the Exchange Offer, we have retained
 
   
    - Morrow & Co., Inc., as Information Agent. If you are an individual or
      institutional shareholder and desire assistance, please call
      1-800-566-9061. Banks or brokerage firms may call 1-800-662-5200.
    
 
   
    - J.P. Morgan Securities Inc., as Dealer Manager. If you are an
      institutional shareholder you may call (212)    -    .
    
 
   
    All shareholders may call the Information Agent to request additional
documents and individual shareholders and banks or brokerage firms should
contact the Information Agent to ask any questions. Institutional shareholders
may call either the Information Agent or the Dealer Manager with any questions.
    
 
    Our Common Shares are listed and traded on the New York Stock Exchange and
the Pacific Exchange, in each case under the symbol WWP.
 
    WWP has a long history of innovation and leadership. We trust you will find
this Exchange Offer is consistent with that legacy.

                 QUESTIONS AND ANSWERS ABOUT THE EXCHANGE OFFER
 
Q1: WHY ARE WE CHANGING THE DIVIDEND POLICY NOW?
 
A1: The utility and energy industries are rapidly changing and abundant
opportunities are emerging to apply our capabilities to serve new markets and
grow the Company for the benefit of shareholders. Reducing the dividend we
currently pay on Common Shares will allow us to retain more of our earnings for
reinvestment in our Company and to fund our growth plans.
 
Q2: WHY ARE WE MAKING THE EXCHANGE OFFER?
 
A2: We recognize that some of you may rely on the income produced by the
dividend we currently pay on Common Shares. Once we made the decision to reduce
the dividend, we decided to create an opportunity for you to retain for a period
of time all or part of the income stream to which you may have been accustomed.
The Exchange Offer is structured to also allow you to benefit from a portion of
the longer term Common Share price growth potential.
 
Q3: WHAT DO I GET IF I EXCHANGE ANY OF MY COMMON SHARES FOR RECONS?
 
   
A3: For each Common Share exchanged you will receive one RECONS on which
quarterly dividends of $0.31 will be paid. Each RECONS will automatically be
converted into one Common Share at the end of three years, unless we choose to
convert earlier, in which case there is a substantial likelihood that you would
receive less than one Common Share (see Question 16).
    
 
Q4: HOW DO RECONS DIFFER FROM PREFERRED STOCK?
 
A4: Each RECONS is a depositary share that constitutes a one-tenth (1/10)
interest in one share of a new series of Preferred Stock of The Washington Water
Power Company ("WWP"), to be designated the $12.40 Preferred Stock, Convertible
Series L, no par value ("New Preferred Stock"). WWP will issue up to 2,000,000
shares of New Preferred Stock from its total of 10,000,000 authorized shares of
Preferred Stock.
 
Q5: WHAT IS A DEPOSITARY SHARE?
 
A5: The Bank of New York, acting as a depositary, holds the New Preferred Stock
under a deposit agreement. The depositary shares, which we are calling RECONS,
are interests in the New Preferred Stock.
 
Q6: WILL RECONS BE PUBLICLY TRADED?
 
A6: There is currently no public market for the RECONS. We will apply to list
the RECONS on the New York Stock Exchange ("NYSE"), but if NYSE listing
requirements are not met, we expect that the RECONS will trade in the over-the-
counter market. You should not assume that there will be an active trading
market for the RECONS.
 
Q7: WILL I BE TAXED ON THE RECONS THAT I RECEIVE IN THE EXCHANGE OFFER?
 
   
A7: The Exchange Offer generally should be tax-free to WWP and its shareholders.
You should consult your tax advisor as to the particular consequences of the
Exchange Offer to you.
    
 
Q8: HOW DOES THE EXCHANGE OFFER WORK?
 
A8: You may tender some or all of your Common Shares, on a one-for-one basis,
for RECONS. Only whole shares may be tendered. The specifics of this Exchange
Offer are described in this document.
 
Q9: WHAT MUST I DO IF I WANT TO EXCHANGE MY COMMON SHARES?
 
   
A9: If your Common Shares are held by your broker you should follow the
instructions from your broker on how to participate in the Exchange Offer, or
contact your broker directly. If you hold your Common Shares directly, you
should follow the instructions for tendering Common Shares in this document
under the caption "The Exchange Offer--Procedure for Tender" beginning on page
20.
    
 
Q10: WHAT MUST I DO IF I DO NOT WANT TO EXCHANGE MY COMMON SHARES?
 
   
A10: IF YOU WANT TO RETAIN YOUR COMMON SHARES, YOU SHOULD NOT TAKE ANY ACTION.
Note, however, that as a holder of Common Shares your interests will be affected
by this Exchange Offer whether or not you choose to exchange your Common Shares,
as explained in this document.
    
 
   
Q11: DO I NEED TO HAVE HELD MY COMMON SHARES PRIOR TO THE DATE OF THIS
PROSPECTUS TO PARTICIPATE IN THE EXCHANGE OFFER?
    
 
   
A11: No. You may tender Common Shares you acquired before or after the date of
this Prospectus, provided that you deliver such Common Shares in accordance with
the procedures and within the time frame described under the caption "The
Exchange Offer--Procedure for Tender" beginning on page 20.
    
 
   
Q12: WHAT WILL I GET TO REPRESENT MY OWNERSHIP OF RECONS?
    
 
   
A12: You will NOT receive a stock certificate, but will instead get:
    
 
- -  if your Common Shares were held by your broker, a statement confirming your
    exchange of Common Shares and the number of your RECONS; or
 
- -  if you held your Common Shares directly, a depositary receipt evidencing your
    RECONS.
 
   
Q13: WILL PARTICIPANTS IN WWP'S DIVIDEND REINVESTMENT PLAN BE ABLE TO
PARTICIPATE IN THE EXCHANGE OFFER?
    
 
   
A13: Yes. Each participant in the Dividend Reinvestment Plan may withdraw and
tender some or all of the whole Common Shares held in his or her plan account.
However, dividend payments on RECONS will be paid in cash and cannot be
automatically reinvested.
    
 
   
Q14: WILL PARTICIPANTS IN THE COMPANY'S 401(K) PLAN BE ABLE TO PARTICIPATE IN
THE EXCHANGE OFFER?
    
 
   
A14: Participants in the Company's 401(k) Plan may tender Common Shares held in
their 401(k) Company Stock Fund, but not in their 401(k) Company Contribution
Account.
    
 
   
Q15: WHAT HAPPENS AT THE END OF THREE YEARS?
    
 
   
A15: On November 1, 2001, each RECONS will be converted into one Common Share,
unless we choose to convert earlier, in which case there is a substantial
likelihood that you would receive less than one Common Share.
    
 
   
Q16: WHAT HAPPENS IF THE COMPANY CONVERTS EARLY?
    
 
   
A16: If we choose to convert before November 1, 2001, for each RECONS you will
receive no more than one Common Share, having a value up to a maximum of
$[      ]. This means that there is a substantial likelihood that you will
receive less than one Common Share for each RECONS, depending upon the value of
Common Shares at the time of the conversion. You will also receive accrued and
unpaid dividends and a premium payable, if any, in cash or Common Shares.

THE COMPANY (SEE PAGE 14)
    
 
   
    Washington Water Power is an energy services company with utility and
subsidiary operations located throughout the United States. We operate as a
regional utility providing electric and natural gas sales and services and as a
national entity providing both energy and non-energy products and services. We

businesses. Avista's subsidiaries include Pentzer Corporation ("Pentzer"),
Avista Energy, Avista Advantage and Avista Labs.
    
 
   
    Changes now underway in the utility and energy industries are creating new
opportunities to expand the Company's businesses and serve new markets. In
pursuing such opportunities, the Company is shifting to a more growth-oriented
strategy in order to achieve its goal of becoming a diversified North American
energy company. Our principal offices are at 1411 East Mission Avenue, Spokane,
Washington 99202 and the telephone number is (509) 489-0500. Our mailing address
is Post Office Box 3727, Spokane, Washington 99220.
    
 
RECENT DEVELOPMENTS
 
    On August 17, 1998, we announced a dividend restructuring and broad
corporate refocus aimed at strengthening our financial position and providing
needed capital to fund our new growth strategy. As part of that initiative, we
announced that we are reducing the annual dividend on our Common Shares from
$1.24 to $.48 per share, effective with the quarterly dividend expected to be
paid in December 1998. This reduced dividend will permit us to use more of our
operating cash flow for growth initiatives and new investment opportunities in
each of our lines of business. We also announced that we intend to change our
corporate name to Avista Corporation and align our businesses under this name in
order to promote a cohesive brand identity.
 
BACKGROUND AND PURPOSE OF THE EXCHANGE OFFER
 
    We chose to make the Exchange Offer because we wanted to give those of you
whose primary objective may be current income the chance to continue receiving
over the next few years the same dividend the Common Shares now pay. We believe
that the Exchange Offer will help our investors adjust to the Company's
transition to a more growth-oriented strategy. In deciding to pursue the
Exchange Offer, we considered, among other things, the advice of our financial
advisors, J.P. Morgan Securities Inc.
 
   
    To review the reasons for the Exchange Offer in greater detail, see page 18.
    
 
THE EXCHANGE OFFER GENERALLY
 
EFFECTS OF THE EXCHANGE OFFER
 
    WWP shareholders will be affected by the Exchange Offer whether or not 
they tender their Common Shares in the Exchange Offer. If you tender all of 
your Common Shares and all such shares are accepted for exchange, you will 
not have a voting common equity interest in WWP until such time as your 
RECONS are converted. As long as you hold RECONS, you will participate only 
up to a certain level of appreciation in the value of Common Shares. If you 
do not tender any of your Common Shares, you will continue to have a voting 
common equity interest in WWP and your ownership interest in the common 
equity will have increased on a percentage basis as a result of the Exchange 
Offer.
 
THE POSITION OF WWP ON THE EXCHANGE OFFER
 
   
    Neither WWP nor the J.P. Morgan Securities Inc., nor any of their directors
or executive officers, makes any recommendation as to whether you should tender
your Common Shares. Among the factors which you should consider when deciding
whether to tender your Common Shares are (1) your view of the relative value of
a single Common Share and a single RECONS, (2) the relative importance you place
on current income versus potential long-term capital appreciation, (3) your
expectation of what the price of a Common Share will be during the next three
years and (4) your investment strategy, including tax considerations. You must
make your own decision as to whether to tender, and, if so, how many of your
shares to tender after reading this Prospectus and consulting with your advisors
based on your own financial position and requirements. We urge you to read this
document very carefully.
    
 
   
CERTAIN FEDERAL INCOME TAX CONSEQUENCES (SEE PAGE 36)
    
 
    The Exchange Offer generally should be tax-free to WWP and its shareholders.
You should consult your tax advisor as to the particular consequences of the
Exchange Offer to you.

COMPARISON OF RIGHTS OF HOLDERS
    

   
    The following table presents certain features of the RECONS and the Common
Shares. This summary, which is based on the current authorized capitalization of
WWP, is not complete, and is subject to the provisions of the Company's Restated
Articles of Incorporation (the "Restated Articles") authorizing the issuance of
the New Preferred Stock and the Articles of Amendment designating the terms of
the New Preferred Stock (the "Articles of Amendment"). You should read this
comparison in conjunction with the more detailed descriptions under "Description
of RECONS" and "Description of Capital Stock." Each RECONS will constitute a
one-tenth interest in a share of New Preferred Stock that we will issue.

                                               may change the dividend level at its

a holder will receive for each RECONS (1) the
"RECONS Optional Conversion Price" plus (2) a
cash amount equal to all accrued and unpaid

The RECONS Optional Conversion Price equals
the number of Common Shares equal to the
lesser of (i) the amount of $     (which is
   % of the closing price of a Common Share
on the NYSE on            1998) divided by
the Current Market Price (as defined herein)
as of the close of business on the second
trading day immediately preceding the day on
which the Company gives notice of such
conversion, and (ii) one Common Share
(subject to certain antidilution
adjustments).

The amount of $      is sometimes called the
"Optional Conversion Price Cap."

The RECONS Optional Conversion Premium means
an amount, in cash, initially equal to $2.09
declining by $.002111 for each day following
December 15, 1998 to the optional conversion
date (computed on the basis of a 360-day year
consisting of twelve 30-day months) and equal
to zero on and after September 15, 2001;
provided, that the Company may, at its
option, deliver a number of shares of Common
Stock equal to the quotient of such amount
divided by the Current Market Price on the
second trading day immediately preceding the
day on which the Company gives notice of such
conversion.
 
The initial RECONS Optional Conversion
Premium of $2.09 represents the difference
between the annual dividend of $1.24 on each
RECONS and an assumed annual dividend of
$0.48 for each Common Share for the period
after December 15, 1998 through September 15,
2001 (i.e. $0.19 per quarter for eleven
quarters). The premium declines to zero on
September 15, 2001; no premium will be paid
on or after September 15, 2001. Dividends
will accrue on the RECONS through the
conversion date.

COMPARISON OF RETURNS
    
 
   
    The center table below illustrates how your investment might change if you
elect to exchange 100 Common Shares for 100 RECONS and the Company exercises its
option to convert those RECONS on September 15, 2001. The table on the right
reflects a continued investment in 100 Common Shares and assumes that there is
no change in the new dividend rate on Common Shares of $0.12 per quarter ($0.48
per year) and that the dividend on the RECONS of $0.31 per quarter is paid. Both
tables exclude the effect of dividend reinvestment, assume that the investment
is held until September 15, 2001, and further assume the following:

calculated as (i) total market value on September 15, 2001 plus total RECONS
dividends paid, minus total market value at commencement of the Exchange Offer,
divided by (ii) total market value at commencement of the Exchange Offer. Actual
investment results may vary depending on a variety of factors including but not
limited to market conditions, actual dividends paid on Common Shares, the number
of RECONS exchanged for Common Shares, whether the RECONS are converted into
Common Shares earlier than September 15, 2001, how long Common Shares are
actually held and any gain or loss on reinvestment of dividends by a holder.
Shareholders should note that the Optional Conversion Price will never be more
than one Common Share for each RECONS and will be a decreasing fraction of one
Common Share as the Current Market Price per Common Share increases over the
Optional Conversion Price Cap.

                     RISK FACTORS/INVESTMENT CONSIDERATIONS
 
   
    You should consider certain risk factors in deciding whether to participate
in the Exchange Offer, including: the limited potential of holders of RECONS to
benefit from gains in the price of Common Shares; the anticipated relative
trading values of the RECONS and the Common Shares; the possible volatility of
the price of Common Shares; the uncertainty of whether there will be a public
market for the RECONS; the loss of voting power if you exchange Common Shares
for RECONS; the reduction in the dividends on Common Shares; the dividend
preference of the RECONS; and the dilution of the Common Shares upon conversion
of the RECONS. See "Risk Factors/Investment Considerations" on page 12.

(a) For purposes of computing the ratios of earnings to fixed charges plus
    preferred dividend requirements, "earnings" consist of net income before
    interest charges and cumulative preferred dividend requirements, plus income
    taxes, plus the estimated interest component of rentals. "Earnings" also
    include allowance for borrowed and other funds used during construction.
    Fixed charges consist of interest charges, the estimated interest component
    of rentals and the pretax dividend requirements on cumulative preferred
    stock. The ratio shown for the June 30 period is based on information for
    the twelve months ended June 30.

       SUMMARY UNAUDITED PRO FORMA CONDENSED CONSOLIDATED FINANCIAL DATA
 
   
    The following unaudited pro forma information is provided to you to aid in
your analysis of the financial aspects of the Exchange Offer. This information
was derived from the audited consolidated financial statements of WWP for the
fiscal year ended December 31, 1997 and the unaudited consolidated financial
statements of WWP for the six-month period ended June 30, 1998. This information
is only a summary and you should read it in conjunction with the historical
consolidated financial statements of WWP that are incorporated by reference
herein and other information that we have filed with the SEC. See "Additional
Information" on page 42.
    
 
   
    The Unaudited Pro Forma Condensed Consolidated Financial Statements give
effect to the following transactions and events: (1) the planned reduction in
the annualized Common Stock dividend from $1.24 per share ($.31 per share each
quarter) to $.48 per share ($.12 per share each quarter), (2) the proposed
exchange of 20,000,000 Common Shares for 20,000,000 RECONS representing
2,000,000 shares of New Preferred Stock and (3) the planned dividend on New
Preferred Stock of $12.40 per share annually and an assumed stated value of $180
per share. The Pro Forma Consolidated Statement of Income Data assumes that
these transactions occurred on the first day of the respective periods presented
and the Pro Forma Consolidated Balance Sheet Data assumes that these
transactions occurred on June 30, 1998.
    
 
    This information is presented to show you what WWP might have looked like 
if the Exchange Offer had occurred for such amount and at the times outlined 
above. You should not rely on the pro forma information as being indicative 
of the historical results that would have been achieved, the future results 
that WWP will experience after the Exchange Offer or the number of Common 
Shares that will be exchanged in the Exchange Offer.

    earnings per share purposes. The estimated preferred stock dividend of $24.8
    million for 1997 and $12.4 million for the first half of 1998 have been
    deducted from net income for purposes of determining basic earnings per
    common share.
 
(b) For purposes of determining diluted earnings per share, the Series L
    Preferred Stock is common stock equivalent (assumed conversion). The
    estimated preferred stock dividends of $24.8 million for 1997 and $12.4

(a) Reflects the issuance of $360 million, or 2,000,000 shares, of Series L
    Preferred Stock assumed to be exchanged for 20,000,000 shares of Common
    Stock. Series L Preferred Stock will be issued in exchange for shares of
    Common Stock on a one-for-ten basis. Each share of Series L Preferred Stock
    will be recorded at its stated value which will be fixed at the market price
    of the Common Stock received in exchange therefor (assumed to be $18 per
    share).
    
 
   
(b) Common Shares received in exchange for the Series L Preferred Stock will be
    recorded as a charge against common equity at cost (market value at the time
    of the exchange) on the Company's Balance Sheet. This will have the effect
    of reducing common equity by $360 million (assuming 20,000,000 shares at $18
    per share). An estimate of $7.8 million of expenses for the Exchange Offer
    has been included as a charge to equity.

                     RISK FACTORS/INVESTMENT CONSIDERATIONS
 
   
    In considering whether or not to tender Common Shares pursuant to the
Exchange Offer, you should consider carefully all of the information set forth
or incorporated in this Prospectus and, in particular, the following risk
factors and investment considerations. In addition, for a discussion of certain
additional uncertainties associated with (1) the business of WWP, as well as (2)
forward-looking statements in this Prospectus, please see "Forward-Looking
Statements" on page 13.
    
 
LIMITED POTENTIAL TO BENEFIT FROM GAINS IN THE COMMON SHARE PRICE
 
   
    We may convert your RECONS before November 1, 2001, in which case you will
receive the number of Common Shares having a value equal to the RECONS Optional
Conversion Price, plus cash equal to accrued and unpaid dividends and the RECONS
Optional Conversion Premium, if any (payable in cash or, at the Company's
option, in Common Shares). If at any time while the RECONS are outstanding the
Common Shares are trading in the marketplace at a market value higher than the
market value of the RECONS Optional Conversion Price, you may expect that we
would convert your RECONS. This would limit your potential to profit from any
increase in the price of the Common Shares above the RECONS Optional Conversion
Price, since you would receive less than one Common Share for each RECONS
required to be exchanged. On the other hand, you are not protected from any
decrease in the trading price of the Common Shares. On            , 1998, the
trading day immediately prior to the commencement of the Exchange Offer, Common
Shares closed at $      per share on the NYSE.
    
 
TRADING VALUE OF THE SECURITIES
 
    Because the RECONS have a different economic structure than the Common
Shares, we do not expect that the two securities will trade at the same price.
Depending on the circumstances discussed in the next paragraph, the RECONS may
trade at a price higher or lower than the Common Shares.
 
POSSIBLE VOLATILITY OF COMMON STOCK PRICE
 
    When your RECONS are converted, whether on November 1, 2001, or earlier, you
will receive a certain number of Common Shares in return. The price of these
Common Shares will be determined in the marketplace and may be influenced by
many factors, including how we perform as a company, how other investors in the
marketplace perceive us and our prospects, how many people are buying and
selling our Common Shares, and generally how the economy and stock markets are
performing.
 
NO PRIOR PUBLIC MARKET FOR RECONS; POSSIBLE WITHDRAWAL OF LISTING ON NYSE
 
    At the time of the Exchange Offer, there will be no public market for the
RECONS. We will apply to have the RECONS listed for trading on the NYSE. Rules
of the NYSE require that the number, total value and number of holders of RECONS
meet certain minimum criteria in order to be listed. If any of these criteria
are not satisfied, the NYSE might not accept the RECONS for listing, in which
case we would withdraw our listing application. We cannot promise that the
RECONS will meet the NYSE's criteria or that, even if they do, the RECONS will
be accepted for listing on the NYSE. If the RECONS are not accepted for listing
on the NYSE, it might be more difficult for you to buy and sell the RECONS,
which could lower their value. In the event that the RECONS cannot be listed on
the NYSE, the Company will use its best efforts to cause them to be listed on
another securities exchange or included in the National Association of
Securities Dealers Automated Quotation System. Again, we cannot promise that we
would be successful in these efforts or that an active trading market for the
RECONS will develop.
 

                                       13
<PAGE>

LOSS OF VOTING POWER
 
    Once you exchange your Common Shares for RECONS, you will not have the 
same rights as a holder of Common Shares. In particular, you will no longer 
be entitled to vote for directors of the Company, except that if we fail to 
pay dividends on the New Preferred Stock (and thus your RECONS) for eighteen 
months the holders of Preferred Stock, as a class, you will have the right to 
elect a majority of the Board of Directors. The voting power of those holders 
of Common Shares who do not tender their shares in the Exchange Offer will be 
increased proportionately.
 
REDUCTION IN COMMON SHARE DIVIDEND PAYMENT; DIVIDEND PREFERENCE OF THE NEW
  PREFERRED STOCK AND THE RECONS
 
   
    On September 15, 1998, we paid a cash dividend of $0.31 per Common Share to
holders of record as of August 25, 1998. However, we expect that thereafter we
will pay dividends at an annual rate not exceeding $0.48 per share ($0.12 per
quarter), a reduction of approximately 61% compared to the $1.24 annual level
paid in the past. We have already announced the dividend reduction for the
dividend payable on December 15, 1998. We are reducing the dividend in order to
enable us to use a greater portion of our operating cash flow for growth
initiatives and new investment opportunities in every area of our business.
After the Exchange Offer, we may pay a higher or lower dividend on the Common
Shares, depending on our future earnings, our financing needs, our financial
condition and other factors, all as determined by the Board of Directors from
time to time. Holders of RECONS will receive payment of dividends before holders
of Common Shares receive any dividend payments.
    
 
DILUTION OF COMMON EQUITY UPON CONVERSION OF THE RECONS
 
    When your RECONS are converted back into a number of Common Shares, whether
at the Mandatory Conversion Date or earlier, the total number of Common Shares
outstanding will be increased by the number of such Common Shares given in
exchange for the RECONS. As a result, each Common Share will represent a smaller
percentage of the Company's total equity than it did while the RECONS were
outstanding.

                                  THE COMPANY
 
    Washington Water Power is an energy services company with operations located
throughout the United States. The Company, which was incorporated in the State
of Washington in 1889, primarily operates in the electric and natural gas
utility businesses. WWP owns Avista, which in turn owns all the Company's
non-regulated energy and non-energy businesses. Avista's subsidiaries include
Pentzer, Avista Energy, Avista Advantage and Avista Labs. At December 31, 1997,
the Company's employees included 1,467 people in its utility operations and
approximately 1,751 people in its majority-owned non-regulated businesses
(energy and non-energy). The Company's corporate headquarters are located at
1411 East Mission Avenue, in Spokane, Washington 99202.

    The Company's operations are organized into four lines of businesses, two of
which comprise its utility operations. The Energy Delivery business provides
electricity and natural gas in a 26,000 square-mile area in eastern Washington
and northern Idaho, with a combined population of approximately 825,000, as of
December 31, 1997, as well as natural gas services in a 4,000 square-mile area
in northeast and southwest Oregon and South Lake Tahoe region of California,
with a combined population of approximately 495,000, as of such date. The
Generation and Resources business includes the generation and production of
electric energy, and short- and long-term electric and natural gas wholesale
sales and wholesale marketing primarily to, and commodity trading with, other
utilities and power brokers in the Western Systems Coordinating Council. The
National Energy Trading and Marketing business, which is conducted through
subsidiaries, focuses on commodity trading, energy marketing and energy related
products and services on a national basis. The non-energy business primarily
consists of Pentzer, a private investment firm.
    
 
    Changes underway in the utility and energy industries are creating new
opportunities to expand the Company's businesses and serve new markets. In
pursuing such opportunities, the Company is shifting its strategic direction to
growth in order to achieve its goal of becoming a diversified North American
energy company. The Company's strategies are described below.
 
ENERGY
 
   
    The Company seeks to strengthen its position of leadership in energy
delivery and generation as well as energy trading and marketing on a local,
regional and national basis. The Company will seek to increase its asset and
customer base through a focus on acquisitions and strategic alliances in all
parts of its business. The Company intends to focus on growing its core energy
business by seeking to acquire control of physical assets, specifically power
generation assets and electric and gas transmission and distribution assets. The
Company expects that initial growth will come at a local and regional level,
with national growth to follow. Key strengths of the Company today include its
position as one of the lowest-cost-producers of power in the nation, expertise
in hydroelectric and power system management, plus capabilities in trading and
wholesale and retail marketing of gas and electric energy. The Company is also
continuing to develop a unique approach to commercialization of fuel cell
technology.
    
 
   
LOCALLY
    
 
   
    WWP is a long-standing leader in the Northwest region of the United States,
providing some of the lowest cost energy to its customers. The Company's
strategy is to add selectively to its already strong foundation of
state-regulated utility assets to solidify its position as a leading supplier of
a low-cost electric and natural gas energy services.
    
 
   
REGIONALLY
    
 
   
    The Company intends to add to its regulated and non-regulated assets on a
regional basis and participate in industry consolidation to further optimize its
assets and create greater economies of scale. In addition to energy delivery and
generation, WWP plans to concentrate on growing its energy trading and marketing
business. The strong growth in this


                                       15
<PAGE>

business is driven by the Company's significant base of knowledge and 
experience in the operation of physical systems--for both natural gas and 
electric energy-- in the region, as well as its relationship-focused approach 
to the customer.
    
 
   
NATIONALLY
    
 
   
    WWP's strong regional energy trading and marketing skills serve as a
platform for the Company's growing national presence. The Company will seek to
expand its customer base through relationships with other energy providers
outside WWP's Northwest stronghold and thereby leverage its existing trading and
marketing skills.
    
 
NON-ENERGY
 
   
    WWP conducts the majority of its non-energy business through its wholly
owned subsidiary, Pentzer Corporation. Pentzer's business strategy is to acquire
controlling interests in a broad range of middle market companies, facilitate
improved productivity and growth, and ultimately sell such companies to the
public or a strategic buyer.
    
 
    The Company's growth strategy will expose the Company to risks associated
with rapid expansion, challenges in recruiting and retaining qualified
personnel, risks associated with acquisitions and joint ventures and increasing
competition. In addition, growth in the energy and trading and marketing
business will expose the Company to increased financial and credit risks
associated with commodity trading activities. The Company believes that its
extensive experience in the electric and gas businesses, coupled with its strong
management team, will allow WWP to effectively manage its transition to a
diversified North American energy company.

                               THE EXCHANGE OFFER
 
BACKGROUND AND PURPOSE
 
   
    The Company is making the Exchange Offer to provide those shareholders whose
primary objective may be current income with an opportunity, subject to the
terms and conditions of the Exchange Offer, to exchange all or a portion of
their Common Shares for an equal number of RECONS entitled to receive an annual
cash dividend of $1.24 per share. The Exchange Offer provides holders of Common
Shares with the option of exchanging their shares for RECONS and receiving a
stated dividend higher than the dividend expected on Common Shares. However, the
Company may convert the RECONS at any time at the RECONS Optional Conversion
Price (plus the RECONS Optional Conversion Premium, if any, and accrued
dividends), which may, at the time of such conversion, be less than the then
existing market price of the Common Shares. In the event of an optional
conversion, there is a substantial likelihood that a holder of RECONS would
receive less than one Common Share for each RECONS. Thus, an investment in the
RECONS does not provide the holder with the same opportunity for share price
appreciation afforded by an investment in the Common Shares.
    
 
TERMS OF THE EXCHANGE OFFER
 
   
    Upon the terms and subject to the conditions described herein and in the
related Letter of Transmittal (which together constitute the Exchange Offer),
the Company is offering to exchange RECONS for up to 20,000,000 Common Shares at
a rate of one RECONS for each Common Share validly tendered prior to the
Expiration Date and not theretofore withdrawn as described under "--Withdrawal
of Tendered Common Shares." The Exchange Offer is being made to all
shareholders, including officers, directors and affiliates of the Company, on
the same terms and conditions, except that participants in the Company's 401(k)
Plan (as defined herein) may not tender Common Shares held in the Company
Contribution Account on the same terms and conditions. If the Exchange Offer is
oversubscribed as described below, only Common Shares validly tendered pursuant
to the Exchange Offer and not withdrawn prior to the Expiration Date will be
eligible for proration. All Common Shares not acquired pursuant to the Exchange
Offer, including Common Shares not purchased because of proration, will be
returned to the tendering shareholders at the Company's expense as promptly as
practicable following the Expiration Date.
    
 
    The Company's obligation to accept Common Shares for exchange pursuant to
the Exchange Offer is subject to certain conditions set forth under
"--Conditions of the Exchange Offer." Among other conditions, the Exchange Offer
is conditioned upon a minimum of 6,000,000 Common Shares being validly tendered
and not withdrawn prior to the Expiration Date (the "Minimum Condition"). If the
Minimum Condition is not satisfied prior to the Expiration Date, the Company
reserves the right (but shall not be obligated) to (i) decline to accept for
exchange and exchange any of the Common Shares tendered and terminate the
Exchange Offer, (ii) waive or reduce the Minimum Condition and, subject to
complying with the applicable rules and regulations of the SEC, accept for
exchange and exchange all Common Shares validly tendered pursuant to the
Exchange Offer, or (iii) extend the Exchange Offer and, subject to the right of
shareholders to withdraw Common Shares until the Expiration Date, retain the
Common Shares which have been tendered during the period or periods for which
the Exchange Offer is extended.
 
    The Company reserves the right at any time or from time to time to amend 
the Exchange Offer in any respect by making a public announcement of such 
amendment subject to complying with the applicable rules and regulations of 
the SEC. If the Company materially changes the terms of the Exchange Offer or 
the information concerning the Exchange Offer, the Company will extend the 
duration of the Exchange Offer to the extent required by the Securities 
Exchange Act of 1934, as amended (the "Exchange Act"). Certain rules 
promulgated under the Exchange Act provide that the minimum period during 
which an offer must remain open following material changes in the terms of 
the offer or information concerning the offer (other than a change in price 
or a change in percentage of securities sought) will depend on the facts and 
circumstances, including the relative materiality of such terms or 
information. The SEC has stated that, as a general rule, it is of the view 
that an offer should remain open for a minimum of five business days from the 
date that notice of such material is first published, sent or given, and that 
if material changes are made with respect to information that approaches the 
significance of price and share levels, a minimum of ten business days may be 
required to allow adequate dissemination and investor response.

 
                                       19
<PAGE>
 
    The tender of any Common Shares pursuant to the Exchange Offer will include
the tender of the associated Rights (as defined herein) under the Rights
Agreement (as defined herein), as described in "Description of Capital
Stock--Preferred Share Purchase Rights." No separate consideration will be paid
for such Rights.
 
EXPIRATION OF THE EXCHANGE OFFER; EXTENSION OF THE EXCHANGE OFFER
 
    The Exchange Offer will expire on the Expiration Date, unless theretofore
extended. The term "Expiration Date" shall mean 12:00 Midnight, New York City
time, on       ,         , 1998, unless and until the Company shall have
extended the period of time for which the Exchange Offer is open, in which event
"Expiration Date" shall mean the latest time and date on which the Exchange
Offer, as so extended by the Company, shall expire.
 
    The Company expressly reserves the right, in its sole discretion, at any
time or from time to time, to extend the period of time during which the
Exchange Offer is open by giving oral or written notice of such extension to the
Exchange Agent. There can be no assurance, however, that the Company will
exercise its right to extend the Exchange Offer. If the Company decides, in its
sole discretion, to increase (except for any increase not in excess of 2% of the
outstanding Common Shares) or decrease the number of Common Shares being sought
in the Exchange Offer and, at the time that notice of such increase or decrease
is first published, sent or given to holders of Common Shares in the manner
specified below, the Exchange Offer is scheduled to expire at any time earlier
than the tenth business day from the date that such notice is first so
published, sent or given, the Exchange Offer will be extended until the
expiration of such ten business day period. As used herein, a "business day"
means any day other than a Saturday, Sunday or federal holiday and consists of
the time period from 12:01 a.m. through 12:00 midnight, New York City time.
 
PRORATION
 
    Upon the terms and subject to the conditions of the Exchange Offer
(including the Minimum Condition), if 20,000,000 or fewer Common Shares have
been validly tendered pursuant to the Exchange Offer and not withdrawn prior to
the Expiration Date, the Company will accept all such Common Shares for
exchange. Upon the terms and subject to the conditions of the Exchange Offer, if
more than 20,000,000 Common Shares have been validly tendered pursuant to the
Exchange Offer and not withdrawn prior to the Expiration Date, the Company will
accept for exchange all Common Shares validly tendered pursuant to the Exchange
Offer and not withdrawn prior to the Expiration Date on a pro rata basis (with
appropriate adjustments to avoid purchases of fractional Common Shares).
 
    The Company does not expect that it would be able to announce the final
proration factor or to commence delivery of RECONS until approximately five NYSE
trading days after the Expiration Date if proration of tendered Common Shares is
required, because of the difficulty in determining the number of Common Shares
validly tendered (including Common Shares tendered pursuant to the guaranteed
delivery procedure described below) and not withdrawn prior to the Expiration
Date. Preliminary results of proration will be announced by press release as
promptly as practicable after the Expiration Date. Holders of Common Shares may
obtain such preliminary information from the Information Agent and may also be
able to obtain such information from their brokers.
 
REGULATORY APPROVALS
 
    Prior to commencing the Exchange Offer, the Company will have received all
material federal or state regulatory approvals necessary to consummate the
Exchange Offer or any transactions contemplated in connection therewith.
 
                                       20
<PAGE>
APPRAISAL RIGHTS
 
    The Exchange Offer will not give rise to dissenter's rights of appraisal
under Washington law.
 
ACCOUNTING TREATMENT
 
    Each share of New Preferred Stock will be recorded on the Company's Balance
Sheet at its stated value which will be fixed at the market price of the Common
Stock received in exchange therefor. Common Stock received in exchange for the
New Preferred Stock will be recorded on the Company's Balance Sheet as a charge
against common equity at cost (market value at the time of the exchange).
 
PROCEDURE FOR TENDER
 
   
    REGISTERED HOLDERS OF COMMON SHARES, AS WELL AS BENEFICIAL OWNERS WHO ARE
DIRECT PARTICIPANTS IN DTC OR WHO ARE PARTICIPANTS IN THE COMPANY'S DIVIDEND
REINVESTMENT AND STOCK PURCHASE PLANS, WHO DESIRE TO PARTICIPATE IN THE EXCHANGE
OFFER SHOULD FOLLOW THE INSTRUCTIONS SET FORTH BELOW AND IN THE LETTER OF
TRANSMITTAL.
    
 
   
    ALL OTHER BENEFICIAL OWNERS OF COMMON SHARES SHOULD FOLLOW THE INSTRUCTIONS
RECEIVED FROM THEIR BROKER OR NOMINEE AND SHOULD CONTACT THEIR BROKER OR NOMINEE
DIRECTLY. THE INSTRUCTIONS SET FORTH BELOW AND IN THE LETTER OF TRANSMITTAL DO
NOT APPLY TO SUCH BENEFICIAL OWNERS.
    
 
   
    To tender Common Shares pursuant to the Exchange Offer, either (a) a
properly completed and duly executed Letter of Transmittal (or manually signed
facsimile thereof) with any required signature guarantees, or an Agent's Message
(as defined below) in the case of a book-entry transfer of shares, and any other
documents required by the Letter of Transmittal must be received by the Exchange
Agent at one of its addresses set forth on the back cover of this Prospectus and
either (i) certificates for the Common Shares to be tendered must be received by
the Exchange Agent at one of such addresses or (ii) such Common Shares must be
delivered pursuant to the procedures for book-entry transfer described below
(and a timely confirmation of such delivery must be received by the Exchange
Agent), in each case by the Expiration Date, or (b) the guaranteed delivery
procedure described below must be complied with.
    
 
   
    The Exchange Agent will establish accounts with respect to the Common Shares
at The Depository Trust Company ("DTC"), for purposes of the Exchange Offer
within two business days after the date of this Prospectus, and any financial
institution that is a participant in DTC's system may make delivery of Common
Shares by causing DTC to transfer such Common Shares into the Exchange Agent's
account in accordance with DTC's procedures. Although delivery of Common Shares
may be effected through book-entry transfer, the Letter of Transmittal (or
manually signed facsimile thereof), or an Agent's Message, and any other
required documents must, in any case, be received by the Exchange Agent at one
of its addresses set forth on the back cover of this Prospectus by the
Expiration Date, or the guaranteed delivery procedure described below must be
complied with. The term "Agent's Message" means a message transmitted through
electronic means by DTC to and received by the Exchange Agent and forming a part
of a book-entry confirmation, which states that DTC has received an express
acknowledgment from the participant tendering the shares that such participant
has received and agrees to be bound by the Letter of Transmittal. DELIVERY OF
THE LETTER OF TRANSMITTAL AND ANY OTHER REQUIRED DOCUMENTS TO DTC DOES NOT
CONSTITUTE DELIVERY TO THE EXCHANGE AGENT.
    
 
   
    Except as otherwise provided below, all signatures on a Letter of
Transmittal must be guaranteed by a firm that is a participant in the Securities
Transfer Agents Medallion Program, the New York Stock Exchange, Inc. Medallion
Signature Program or the Stock Exchange Medallion Program (each being an
"Eligible Institution"). Signatures on a Letter of Transmittal need not be
guaranteed if (a) the Letter of Transmittal is signed by the registered holder
of the Common Shares tendered therewith and such holder has not completed the
boxes entitled "Special Issue Instructions" or "Special Delivery Instructions"
on the Letter of Transmittal or (b) such Common Shares are tendered for the
account of an Eligible Institution. See Instructions 1 and 5 of the Letter of
Transmittal.
    
 
                                       21
<PAGE>
    If a shareholder desires to tender Common Shares pursuant to the Exchange
Offer and cannot deliver such Common Shares and all other required documents to
the Exchange Agent by the Expiration Date, such Common Shares may nevertheless
be tendered if all of the following conditions are met:
 
        (i) such tender is made by or through an Eligible Institution;
 
        (ii) a properly completed and duly executed Notice of Guaranteed
    Delivery substantially in the form provided by the Company is received by
    the Exchange Agent (as provided below) by the Expiration Date; and
 
   
       (iii) the certificates for such Common Shares (or a confirmation of a
    book-entry transfer of such Common Shares into the Exchange Agent's account
    at DTC), together with a properly completed and duly executed Letter of
    Transmittal (or manually signed facsimile thereof), or an Agent's Message in
    connection with a book-entry transfer, and any other documents required by
    the Letter of Transmittal, are received by the Exchange Agent within three
    NYSE trading days after the date of execution of the Notice of Guaranteed
    Delivery.
    
 
    The Notice of Guaranteed Delivery may be delivered by hand or transmitted by
telegram, telex, facsimile transmission or mail to the Exchange Agent and must
include a Guarantee by an Eligible Institution in the form set forth in such
Notice.
 
   
    Shareholders who are participants in the Company's Dividend Reinvestment and
Stock Purchase Plan may tender some or all of the Common Shares held in their
plan account. However, dividend payments on RECONS received in exchange for such
Common Shares will be paid in cash and cannot be automatically reinvested under
the plan. Holders wishing to tender Common Shares should so indicate by checking
the appropriate box in the section of the Letter of Transmittal captioned
"Description of Common Shares Tendered in the Exchange Offer" and returning the
properly completed and duly executed Letter of Transmittal or manually signed
facsimile thereof with any required signature guarantees and any other documents
required by the Letter of Transmittal to the Exchange Agent.
    
 
   
    Participants in the Company's Investment and Employee Stock Ownership Plan
(the "401(k) Plan") may tender Common Shares held in their 401(k) Company Stock
Fund. Any Common Shares held in the Company Contribution Account in the 401(k)
Plan may not be tendered. Dividend payments on RECONS received in exchange for
Common Shares which were originally held under the 401(k) Plan will
automatically be invested in Common Shares. Shareholders who wish to tender
Common Shares held in their 401(k) Company Stock Fund should complete and return
the 401(k) Election to Tender Shares of Common Stock to the plan record keeper,
Howard Johnson & Company. Any plan account Common Shares tendered but not
accepted for exchange will be returned to the shareholder's applicable plan
account.
    
 
   
    PARTICIPANTS WHO HOLD COMMON SHARES IN THEIR 401(K) COMPANY STOCK FUND UNDER
THE 401(K) PLAN MAY NOT USE THE LETTER OF TRANSMITTAL TO DIRECT THE TENDER OF
COMMON SHARES, BUT MUST USE THE SEPARATE ELECTION FORM SENT TO THEM.
    
 
   
    If any certificate representing Common Shares has been mutilated, destroyed,
lost or stolen, the shareholder must (i) furnish to the Exchange Agent evidence,
satisfactory to it in its discretion, of the ownership of and destruction, loss
or theft of such certificate, (ii) furnish to the Exchange Agent indemnity
satisfactory to it in its discretion and (iii) comply with such other reasonable
regulations as the Exchange Agent may proscribe.
    
 
    The tender of Common Shares pursuant to the Exchange Offer in accordance
with the procedures described above will constitute an agreement between the
tendering shareholder and the Company upon the terms and subject to the
conditions of the Exchange Offer, including the tendering shareholder's
representation and warranty that (i) such shareholder owns the Common Shares
being tendered within the meaning of Rule 14e-4 under the Exchange Act and (ii)
the tender of such Common Shares complies with Rule 14e-4.

    It is a violation of Rule 14e-4 under the Exchange Act for a person,
directly or indirectly, to tender Common Shares for his own account unless the
person so tendering (i) has a net long position equal to or greater than the
number of (x) Common Shares tendered or (y) other securities immediately
convertible into, or exercisable or exchangeable for, the number of Common
Shares tendered and will acquire such Common Shares for tender by conversion,
exercise or exchange of such other securities and (ii) 
 
                                       22
<PAGE>

will cause such Common Shares to be delivered in accordance with the terms of 
the Exchange Offer. Rule 14e-4 provides a similar restriction applicable to 
the tender or guarantee of a tender on behalf of another person. The tender 
of Common Shares pursuant to the procedures described above will constitute 
the tendering shareholder's representation and warranty that (i) such 
shareholder has a net long position in the Common Shares being tendered 
within the meaning of Rule 14e-4 under the Exchange Act and (ii) the tender 
of such Common Shares complies with Rule 14e-4.
 
    All questions as to the form of documents and the validity, eligibility
(including time of receipt) and acceptance for exchange of any tender of Common
Shares will be determined by the Company, in its sole discretion, which
determination shall be final and binding. The Company reserves the absolute
right to reject any or all tenders of Common Shares determined by it not to be
in proper form or to reject Common Shares the acceptance of exchange or exchange
of which may, in the opinion of the Company's counsel, be unlawful. The Company
also reserves the absolute right to waive any defect or irregularity in any
tender of Common Shares. None of the Company, the Exchange Agent, the
Information Agent or any other person will be under any duty to give
notification of any defect or irregularity in tenders or incur any liability for
failure to give any such notification.
 
   
    THE METHOD OF DELIVERY OF ALL DOCUMENTS, INCLUDING CERTIFICATES FOR COMMON
SHARES, IN CONNECTION WITH TENDERING PURSUANT TO THE EXCHANGE OFFER IS AT THE
ELECTION AND RISK OF THE TENDERING SHAREHOLDER AND, EXCEPT AS OTHERWISE PROVIDED
IN THE LETTER OF TRANSMITTAL, DELIVERY WILL BE DEEMED MADE ONLY WHEN ACTUALLY
RECEIVED BY THE EXCHANGE AGENT. IF DELIVERY IS BY MAIL, REGISTERED MAIL WITH
RETURN RECEIPT REQUESTED, INSURED FOR AT LEAST 2% OF THE MARKET VALUE OF THE
COMMON SHARES, IS RECOMMENDED AND SUFFICIENT TIME SHOULD BE ALLOWED TO ASSURE
TIMELY DELIVERY.
    
 
WITHDRAWAL OF TENDERED COMMON SHARES
 
    Tenders of Common Shares made pursuant to the Exchange Offer may be
withdrawn at any time prior to the Expiration Date. Thereafter, such tenders are
irrevocable, except that they may be withdrawn after             , 1998 unless
theretofore accepted for exchange as provided in this Prospectus. If the Company
extends the period of time during which the Exchange Offer is open, is delayed
in accepting for exchange or exchanging Common Shares or is unable to accept for
exchange or to exchange Common Shares pursuant to the Exchange Offer for any
reason, then, without prejudice to the Company's rights under the Exchange
Offer, the Exchange Agent may, on behalf of the Company, retain all Common
Shares tendered, and such Common Shares may not be withdrawn except as otherwise
provided herein, subject to Rule 13e-4(f)(5) under the Exchange Act, which
provides that the issuer making the tender offer shall either pay the
consideration offered, or return the tendered securities, promptly after the
termination or withdrawal of the tender offer.
 
   
    A Holder whose Common Shares are held through a broker and who has tendered
any or all of such shares pursuant to the Exchange Offer may withdraw such
tender only by directly contacting the broker and following the broker's
withdrawal instructions. Participants in the Company's 401(k) Plan who have
tendered Common Shares held in their 401(k) Company Stock Fund may only withdraw
such tender by contacting the plan record keeper, Howard Johnson & Company, and
following the record keeper's withdrawal instructions. The broker or plan record
keeper, as the case may be, should be contacted as promptly as possible and with
sufficient time to allow such party to withdraw the applicable tender prior to
the Expiration Date.
    
 
   
    In order for the withdrawal of a tender of Common Shares held by a 
registered holder, or of Common Shares held in the Dividend Reinvestment and 
Stock Purchase Plan, to be effective, a written, telegraphic, telex or 
facsimile transmission notice of withdrawal must be timely received by the 
Exchange Agent at one of its addresses set forth on the back cover of this 
Prospectus and must specify the name of the person who tendered the Common 
Shares to be withdrawn and the number of Common Shares to be withdrawn with 
respect to the Exchange Offer. If the Common Shares to be withdrawn have been 
delivered to the Exchange Agent, a signed notice of withdrawal with 
signatures guaranteed by an Eligible Institution (except in the case of 
Common Shares tendered by an Eligible Institution) must be submitted prior to 
the release of such Common Shares. In addition, such notice must specify, in 
the case of Common Shares tendered by delivery of certificates, the name of 
the registered holder (if different from that of the tendering shareholder) 
and the certificate numbers shown on the particular certificates evidencing 
the Common Shares to be withdrawn or, in the case of Common Shares tendered 
by book-entry transfer, the name and number of the account at the DTC to be 
credited with the withdrawn Common Shares. Withdrawals may not be rescinded 
and Common Shares withdrawn will thereafter be deemed not validly tendered 
for purposes of the Exchange Offer. However, withdrawn Common 


                                       23
<PAGE>

Shares may be tendered again by following one of the procedures described in 
"--Procedure for Tender" at any time prior to the Expiration Date.
    

    All questions as to the form and validity (including time of receipt) of any
notice of withdrawal will be determined by the Company, in its sole discretion,
which determination shall be final and binding. None of the Company, the
Exchange Agent, the Information Agent or any other person will be under any duty
to give notification of any defect or irregularity in any notice of withdrawal
or incur any liability for failure to give any such notification.
 
ACCEPTANCE; DELIVERY OF CONSIDERATION
 
    Upon the terms and subject to the conditions of the Exchange Offer, and as
promptly as practicable after the Expiration Date, the Company will (subject to
the proration provisions of the Exchange Offer) accept for exchange (and thereby
acquire) and exchange for RECONS the Common Shares validly tendered pursuant to
the Exchange Offer by the Expiration Date and not withdrawn as permitted under
"--Withdrawal of Tendered Common Shares" above. In all cases, delivery of the
RECONS to exchanging holders of Common Shares will be made as soon as
practicable after the Expiration Date (subject to possible delay in the event of
proration) but only after timely receipt by the Exchange Agent of certificates
for Common Shares (or of a confirmation of a book-entry transfer of such Common
Shares into the Exchange Agent's account at DTC), a properly completed and duly
executed Letter of Transmittal (or manually signed facsimile thereof), or an
Agent's Message in the case of a book-entry transfer of Common Shares, and any
other required documents. In addition, the Company reserves the right, in its
sole discretion (subject to Rule 13e-4(f)(5) under the Exchange Act), to delay
the acceptance for exchange or to delay exchange of any Common Shares in order
to comply in whole or in part with applicable law.
 
    For purposes of the Exchange Offer, the Company will be deemed to have
accepted for exchange (and thereby acquired), subject to the proration
provisions of the Exchange Offer, Common Shares that are validly tendered
pursuant to the Exchange Offer prior to the Expiration Date and not withdrawn
as, if and when it gives oral or written notice to the Exchange Agent of its
acceptance for exchange of Common Shares tendered pursuant to the Exchange
Offer. The Exchange Agent will act as agent for tendering shareholders for the
purpose of (i) receiving RECONS from the Company in exchange for Common Shares
tendered pursuant to the Exchange Offer and (ii) delivering RECONS to tendering
shareholders. Under no circumstances will interest be paid on RECONS to be
delivered to tendering shareholders by the Company by reason of any delay in
making such delivery.

   
    Certificates for all Common Shares not acquired by the Company pursuant 
to the Exchange Offer for any reason will be returned (or, in the case of 
Common Shares tendered by book-entry transfer, such Common Shares will be 
credited to an account maintained with DTC) as soon as practicable (subject 
to possible delay in the event of proration) without expense to the tendering 
shareholder. The Company will pay all stock transfer taxes, if any, payable 
on the transfer to it of Common Shares purchased pursuant to the Exchange 
Offer, except as set forth in Instruction 87 of the Letter of Transmittal.
    
 
    Delivery of RECONS in exchange for Common Shares may be delayed in the event
of difficulty in determining the number of Common Shares validly tendered or if
proration is required. See "--Proration" above. In addition, if certain
conditions are not satisfied, the Company may not be obligated to exchange
RECONS pursuant to the Exchange Offer. See "--Conditions of the Exchange Offer"
below. As provided in Rules 13e-4(f)(4) and (8)(ii) under the Exchange Act, the
Company will deliver the same consideration per Common Share for each Common
Share accepted pursuant to the Exchange Offer.
 
CONDITIONS OF THE EXCHANGE OFFER
 
    It is a condition of the Exchange Offer that a minimum of 6,000,000 Common
Shares be validly tendered pursuant to the Exchange Offer by the Expiration Date
and not withdrawn.
 
    In addition, notwithstanding any other provision of the Exchange Offer, the
Company shall not be required to accept for exchange or to exchange any Common
Shares tendered pursuant to the Exchange Offer, and may terminate or amend the
Exchange Offer or may postpone (subject to the requirements of the Exchange Act
for prompt exchange or return of Common 


                                       24
<PAGE>

Shares) the acceptance for exchange and exchange of Common Shares tendered, 
if at any time on or after             , 1998 and before acceptance for 
exchange or exchange of any such Common Shares any of the following shall 
have occurred:
 
        (a) there shall have been threatened, instituted or pending any action
    or proceeding by any government or governmental, regulatory or
    administrative agency or authority or tribunal or any other person, domestic
    or foreign, before any court, authority, agency or tribunal which (i)
    challenges the making of the Exchange Offer, the issuance of the New
    Preferred Stock, the acquisition of some or all of the Common Shares
    pursuant to the Exchange Offer or otherwise relates in any manner to the
    Exchange Offer, or (ii) in the Company's sole judgment, could materially
    affect the business, condition (financial or other), income, operations or
    prospects of the Company and its subsidiaries, taken as a whole, or
    otherwise materially impair in any way the contemplated future conduct of
    the business of the Company or any of its subsidiaries or materially impair
    the contemplated benefits of the Exchange Offer to the Company;
 
        (b) there shall have been any action threatened, pending or taken, or
    approval withheld, or any statute, rule, regulation, judgment, order or
    injunction threatened, proposed, sought, promulgated, enacted, entered,
    amended, enforced or deemed to be applicable to the issuance of the New
    Preferred Stock or the Exchange Offer or the Company or any of its
    subsidiaries, by any court or any authority, agency or tribunal which, in
    the Company's sole judgment, would or might directly or indirectly (i) make
    the issuance of the New Preferred Stock or the acceptance for exchange or
    exchange of some or all of the Common Shares illegal or otherwise restrict
    or prohibit consummation of the Exchange Offer; (ii) delay or restrict the
    ability of the Company, or render the Company unable, to issue the New
    Preferred Stock or to accept for exchange or to exchange some or all of the
    Common Shares; (iii) materially impair the contemplated benefits of the
    Exchange Offer to the Company; or (iv) materially affect the business,
    condition (financial or other), income, operations or prospects of the
    Company and its subsidiaries, taken as a whole, or otherwise materially
    impair in any way the contemplated future conduct of the business of the

    significant decrease in the market price of the Common Shares or any

    the foregoing existing at the time of the commencement of the Exchange
    Offer, a material acceleration or worsening thereof or (vii) any decline in

    close of business on             , 1998) by an amount in excess of

        (d) any tender or exchange offer with respect to some or all of the

from time to time in its sole discretion, with respect to the Exchange Offer.

not be deemed a waiver of any such right; the waiver of any such right with
respect to particular facts and circumstances shall not be deemed a waiver with
respect to any other facts or circumstances; and each such right shall be deemed
an ongoing right which may be asserted at any time and from time to time. Any
determination by the Company concerning the events described above will be final
and binding on all parties.

                             DESCRIPTION OF RECONS
 
GENERAL
 
   
    Each RECONS constitutes a one-tenth (1/10) ownership interest in one share
of a New Preferred Stock deposited under the Deposit Agreement (the "Deposit
Agreement"), to be entered into between the Company and The Bank of New York, as
depositary (the "Preferred Stock Depositary). Subject to the terms of the
Deposit Agreement, each owner of a RECONS is entitled, proportionately, to all
the rights, preferences and privileges of the New Preferred Stock (including
dividend, voting and liquidation rights), and subject, proportionately, to all
of the limitations of the New Preferred Stock, all as set forth in the Articles
of Amendment to the Company's Restated Articles of Incorporation, as amended,
summarized under "Description of Capital Stock."
    
 
   
    The RECONS will be evidenced by depositary receipts issued pursuant to the
Deposit Agreement (the "Depositary Receipts"). The following summary of the
terms and provisions of the RECONS does not purport to be complete and is
subject to, and qualified in its entirety by, the Deposit Agreement (which
contains the form of Depositary Receipt). Copies of the Deposit Agreement are
available for inspection at the corporate office of the Preferred Stock
Depositary located at The Bank of New York, 101 Barclay Street, New York, New
York 10286.
    
 
ISSUANCE OF DEPOSITARY RECEIPTS
 
   
    Upon issuance of the New Preferred Stock by the Company, the Company will
deposit the New Preferred Stock with the Preferred Stock Depositary, which will
execute and deliver the Depositary Receipts to the Company. The Company will, in
turn, deliver the Depositary Receipts to the Exchange Agent which will deliver
the Depositary Receipts to the owners of RECONS evidenced thereby. Depositary
Receipts will be issued evidencing whole RECONS only.
    
 
WITHDRAWAL OF NEW PREFERRED STOCK
 
    Upon surrender of Depositary Receipts at the principal office of the
Preferred Stock Depositary, upon payment of a sum sufficient for the payment of
any tax or other governmental charge with respect thereto, and subject to the
terms of the Deposit Agreement, the owner of the RECONS evidenced thereby is
entitled to delivery of the number of whole shares of New Preferred Stock
represented by such RECONS. Fractional shares of New Preferred Stock will not be
issued. If the Depositary Receipts delivered by the holder evidence a number of
RECONS in excess of the number of RECONS representing the number of whole shares
of New Preferred Stock to be withdrawn, the Preferred Stock Depositary will
deliver to such holder at the same time a new Depositary Receipt evidencing such
excess number of RECONS. Holders of New Preferred Stock thus withdrawn will not
thereafter be entitled to deposit such shares under the Deposit Agreement or to
receive Depositary Receipts evidencing RECONS therefor. There is currently no
market for New Preferred Stock and it is not expected that an active trading
market for New Preferred Stock will develop. All trading is expected to be in
RECONS.
 
CONVERSION OF RECONS
 
   
    As described under "Description of Capital Stock--Mandatory Conversion" and
"--Optional Conversion," the New Preferred Stock is subject (i) to conversion
into Common Shares on the Mandatory Conversion Date (or in connection with
certain mergers, consolidations or other extraordinary transactions of the
Company), and (ii) to the right of the Company, at its option, to convert
    
 
                                       28
<PAGE>

the New Preferred Stock into Common Shares at any time prior to the Mandatory 
Conversion Date. Upon any such conversion, each RECONS will constitute an 
interest in Common Shares, with the number of such Common Shares being equal 
to one-tenth of the number of Common Shares into which each share of New 
Preferred Stock was converted. When the RECONS are converted into Common 
Shares and all of such Common Shares cannot be distributed to the record 
holders of Depositary Receipts without creating fractional interests in such 
shares, the Preferred Stock Depositary may, with the consent of the Company, 
adopt such method as it deems equitable and practicable for the purpose of 
effecting such distribution, including the public or private sale of such 
shares representing in the aggregate such fractional interests at such places 
and upon such terms as it may deem proper, and the net proceeds of any such 
sale shall be distributed or made available for distribution to such record 
holders that would otherwise have received fractional interests in such 
shares. The amount distributed in the foregoing cases will be reduced by any 
amounts required to be withheld by the Company or the Preferred Stock 
Depositary on account of taxes or otherwise required pursuant to law, 
regulation or court process.
 
DIVIDENDS AND OTHER DISTRIBUTIONS
 
   
    The Preferred Stock Depositary will distribute all cash dividends or other
cash distributions in respect of the New Preferred Stock represented by the
RECONS to the record holders of Depositary Receipts in proportion to the number
of RECONS owned by such holders on the relevant record date, which will be the
same date as the corresponding record date fixed by the Company for the New
Preferred Stock. In each case where a holder of RECONS would otherwise be
entitled to receive a fraction of a cent, the Preferred Stock Depositary will
round the amount of the distribution up to the next whole cent.
    
 
   
    In the event of a distribution other than in cash, the Preferred Stock
Depositary will distribute property to the record holders of Depositary Receipts
entitled thereto, in proportion, as nearly as may be practicable, to the number
of RECONS owned by such holders on the relevant record date, unless the Company
determines that it is not feasible to make such distribution, in which case the
Preferred Stock Depositary may adopt any other method for such distribution as
it deems appropriate, including the sale of such property and distribution of
the net proceeds from such sale to such holders.
    
 
    The amount distributed in any of the foregoing cases will be reduced by any
amount required to be withheld by the Company or the Preferred Stock Depositary
on account of taxes.
 
RECORD DATE
 
   
    Whenever (i) any cash dividend or other cash distribution shall become
payable, any distribution other than cash shall be made, or any rights,
preferences or privileges shall be offered with respect to the New Preferred
Stock, or (ii) the Depositary shall receive notice of any meeting at which
holders of New Preferred Stock are entitled to vote or of which holders of New
Preferred Stock are entitled to notice, the Preferred Stock Depositary shall in
each such instance fix a record date (which shall be the same date as the
corresponding record date for the New Preferred Stock) for the determination of
the holders of Depositary Receipts (x) who shall be entitled to receive such
dividend, distribution, rights, preferences or privileges or the net proceeds of
the sale thereof, (y) who shall be entitled to give instructions for the
exercise of voting rights at any such meeting or to receive notice of such
meeting, or (z) who shall be entitled to receive notice of conversion or other
events, subject to the provisions of the Deposit Agreement.
    
 
PROCEDURES FOR VOTING
 
   
    Promptly upon receipt of notice of any meeting at which the holders of New
Preferred Stock are entitled to vote, the Preferred Stock Depositary (unless
another arrangement for allowing holders of RECONS to exercise the voting rights
associated with the New Preferred Stock is agreed to by the Company and the
Preferred Stock Depositary) will cause the information contained in such notice
of meeting to be mailed to the record holders of Depositary Receipts as of the
record date for such meeting. Each such record holder of Depositary Receipts
will be entitled to instruct the Preferred Stock Depositary as to the exercise
of voting rights with respect to the number of shares of New Preferred Stock
represented by such holder's RECONS. The Preferred Stock
    
 
                                       29
<PAGE>
   
Depositary, as registered holder of such shares of New Preferred Stock, will 
endeavor, insofar as practicable, to vote with respect to the number of 
shares of New Preferred Stock represented by such RECONS in accordance with 
such instructions, and the Company intends to take all action which may be 
deemed necessary by the Preferred Stock Depositary in order to enable the 
Preferred Stock Depositary to do so. The Preferred Stock Depositary will 
abstain from voting with respect to the New Preferred Stock to the extent 
that it does not receive specific written instructions from the holders of 
Depositary Receipts.
    
 
AMENDMENT AND TERMINATION OF DEPOSIT AGREEMENT
 
   
    The form of Depositary Receipt evidencing the RECONS and any provision of
the Deposit Agreement may at any time and from time to time be amended by
agreement between the Company and the Preferred Stock Depositary. However, any
amendment which imposes or increases any fees, taxes or charges upon holders of
RECONS (other than taxes and other governmental charges, fees and other expenses
payable by such holders as provided for in the Deposit Agreement or Depositary
Receipt and as stated under "--Charges of Preferred Stock Depositary"), or which
otherwise prejudices any substantial existing right of holders of RECONS, will
not take effect as to outstanding RECONS until the expiration of 30 days after
notice of such amendment has been given to the record holders of outstanding
RECONS. Every holder of an outstanding RECONS at the time any such amendment
becomes effective will be deemed, by continuing to hold such RECONS, to consent
and agree to such amendment and to be bound
by the Deposit Agreement as amended thereby. No such amendment may impair the
right, subject to the terms of the Deposit Agreement, of any owner of any RECONS
to surrender the Depositary Receipt evidencing such RECONS with instructions to
the Preferred Stock Depositary to deliver to the holder the New Preferred Stock
or Common Stock, as applicable, represented thereby, except in order to comply
with mandatory provisions of applicable law.
    
 
   
    The Deposit Agreement may be terminated by the Company or the Preferred
Stock Depositary only if (i) the New Preferred Stock has been converted or (ii)
there has been a final distribution in respect of the New Preferred Stock (or
the Common Stock into which the New Preferred Stock shall have been converted)
in connection with any liquidation, dissolution or winding up of the Company and
such distribution has been made to all the holders of RECONS. The Company and
the Preferred Stock Depositary will undertake to terminate the Deposit Agreement
upon such conversion or distribution.
    
 
CHARGES OF PREFERRED STOCK DEPOSITARY
 
   
    The Company will pay all transfer and other taxes and governmental charges
arising solely from the existence of the depositary arrangements. The Company
will pay charges of the Preferred Stock Depositary in connection with the
initial deposit of the New Preferred Stock and the initial issuance of the
RECONS, the conversion of the New Preferred Stock and all withdrawals of the New
Preferred Stock by owners of RECONS. Holders of Depositary Receipts will pay
transfer, income and other taxes and governmental charges and charges incurred
by the Preferred Stock Depositary at the election of a holder, as provided in
the Deposit Agreement. In certain circumstances, the Preferred Stock Depositary
and the Company may refuse to transfer RECONS, may withhold dividends and
distributions and may sell the RECONS evidenced by such Depositary Receipt if
such charges are not paid.
    
 
MISCELLANEOUS
 
    Application will be made to list the RECONS on the NYSE upon official notice
of issuance and subject to adequacy of distribution and other listing
requirements. If these conditions are not met, it is expected that the RECONS
will trade in the over-the-counter market.
 
   
    The Company will deliver to the Preferred Stock Depositary all reports to 
shareholders and other communications which the Company is required to 
furnish to the holders of New Preferred Stock by law, by the rules of the 
NYSE or any other stock exchange or trading market on which the RECONS are 
listed or by the Restated Articles of Incorporation of the Company. The 
Preferred Stock Depositary will forward to the holders of RECONS and will 
make available for inspection by holders of RECONS, at the principal office 
of the Preferred Stock Depositary and at such other places as it may from 
time to time deem advisable, any such report and communications received from 
the Company.
    
 
                                       30
<PAGE>
 
    Neither the Preferred Stock Depositary nor the Company will be subject to
any liability under the Deposit Agreement to holders of Depositary Receipts
other than for its negligence, bad faith or willful misconduct. Neither the
Preferred Stock Depositary nor the Company will be liable if it is prevented or
delayed by law or any circumstance beyond its control in performing its
obligations under the Deposit Agreement. The obligations of the Company and the
Preferred Stock Depositary under the Deposit Agreement will be limited to
performance in good faith of their duties thereunder, and they will not be
obligated to prosecute or defend any legal proceeding in respect of any RECONS
or shares of New Preferred Stock unless satisfactory indemnity is furnished. The
Company and the Preferred Stock Depositary may rely on written advice of counsel
or accountants, on information provided by holders of RECONS or other persons
believed in good faith to be competent to give such information and on documents
believed to be genuine and to have been signed or presented by the proper party
or parties.
 
RESIGNATION AND REMOVAL OF PREFERRED STOCK DEPOSITARY
 
    The Preferred Stock Depositary may resign at any time by delivering to the
Company notice of its election to do so. The Company may at any time, by notice,
remove the Preferred Stock Depositary or may terminate the engagement of the
Preferred Stock Depositary with respect to any or all of its duties and
obligations under the Deposit Agreement. Any such resignation, removal or
termination will take effect upon the appointment of a successor Preferred Stock
Depositary and such successor's acceptance of such appointment with respect to
all the predecessor's duties and obligations so terminated. Such successor
Preferred Stock Depositary must be appointed within 45 days after delivery of
the notice for resignation, removal or termination and, if the predecessor is to
acquire title to New Preferred Stock, must be a bank or trust company having its
principal office in the United States of America and having a combined capital
and surplus of at least $50,000,000.
 
                          DESCRIPTION OF CAPITAL STOCK
 
GENERAL
 
   
    The authorized capital stock of the Company consists of 10,000,000 shares of
Preferred Stock, cumulative, without par value (the "Preferred Stock"), and
200,000,000 shares of Common Stock without par value (the "Common Stock"). As of
September 30, 1998, the Company had 55,960,360 shares of Common Stock issued and
outstanding. Shares of the Common Stock are sometimes herein called "Common
Shares." For a detailed description of the terms and characteristics of the
capital stock of the Company, reference is made to the Company's Restated
Articles of Incorporation (the "Restated Articles"), the form of the proposed
Articles of Amendment (the "Articles of Amendment") and the Company's Bylaws, as
amended (the "Bylaws"), copies of which are exhibits to the Registration
Statement, and to the laws of the State of Washington. Following is a brief
summary of such terms and characteristics, which does not purport to be complete
and is qualified in its entirety by the foregoing references.
    
 
   
    The Restated Articles provide that the Preferred Stock may be divided 
into and issued from time to time in one or more series. All shares of 
Preferred Stock constitute one and the same class of stock, are of equal rank 
and will otherwise be identical except as to the designation thereof, the 
date or dates from which dividends on shares thereof will be cumulative, and 
except that each series may vary as to (a) the rate or rates of dividend, if 
any, which may be expressed in terms of a formula or other method by which 
such rate or rates will be calculated from time to time, and the date or 
dates on which dividends may be payable, (b) whether shares may be redeemed 
and, if so, the redemption price and terms and conditions of redemption, (c) 
the amount payable on voluntary and involuntary liquidation, (d) sinking fund 
provisions, if any, for the redemption or purchase of shares, and (e) the 
terms and conditions, if any, on which shares may be converted. When 
Preferred Stock is initially issued, the number of shares constituting such 
series, its distinguishing serial designation and its particular 
characteristics (insofar as there may be variations between series) may be 
fixed by resolution of the Board of Directors.
    
 
                                       31
<PAGE>
 
DIVIDEND RIGHTS
 
    The New Preferred Stock will be entitled, on a parity with each other series
of Preferred Stock and in preference to the Common Stock, to receive, but only
when and as declared by the Board of Directors, dividends at the rate of $12.40
per share per annum; provided, however, that the dividend payable on December
15, 1998 will be $3.10 per share. Such dividends will be cumulative from the
date of issuance of the New Preferred Stock and will be payable on the fifteenth
day of March, June, September and December in each year, commencing December 15,
1998.
 
    After full provision for all Preferred Stock dividends declared or in
arrears, the holders of Common Stock of the Company are entitled to receive such
dividends as may be lawfully declared from time to time by the Board of
Directors of the Company.
 
LIQUIDATION RIGHTS
 
   
    The New Preferred Stock will be entitled, upon dissolution or liquidation,
on a parity with each other series of Preferred Stock and in preference to the
Common Stock, to a liquidation preference per share plus an amount equivalent to
accrued and unpaid dividends thereon, if any, to the date of such event. The
liquidation preference will be an amount equal to ten (10) times the average of
the high and low sale prices of the Common Shares on the NYSE as of the end of
the regular session on the trading date next preceding the date of issuance of
the New Preferred Stock, as reported in the consolidated reporting system.
    
 
    In the event of any dissolution or liquidation of the Company, after
satisfaction of the preferential liquidation rights of the Preferred Stock, the
holders of the Common Stock would be entitled to share ratably in all assets of
the Company available for distribution to shareholders.
 
CONVERSION
 
MANDATORY CONVERSION
 
   
    On the Mandatory Conversion Date (November 1, 2001), each outstanding share
of New Preferred Stock will be mandatorily converted into (i) a number of Common
Shares determined by reference to the Common Equivalent Rate and (ii) the right
to receive a cash amount equal to all accrued and unpaid dividends on such share
of New Preferred Stock to but excluding the Mandatory Conversion Date.
    
 
    The "Common Equivalent Rate" initially will be ten Common Shares for each 
share of New Preferred Stock, subject to adjustment in the event that the 
Company shall (i) pay a dividend or make a distribution with respect to its 
Common Stock in shares of Common Stock, (ii) subdivide, reclassify or split 
its outstanding shares of Common Stock into a greater number of shares, (iii) 
combine or reclassify its outstanding shares of Common Stock into a smaller 
number of shares, (iv) issue by reclassification of its Common Stock any 
shares of Common Stock other than in an Extraordinary Transaction (as defined 
below), (v) issue certain rights or warrants to all holders of its Common 
Stock, (vi) pay a dividend or make a distribution to all holders of its 
Common Stock of evidences of its indebtedness or other assets (including 
shares of capital stock of the Company (other than Common Stock) but 
excluding any distributions and dividends referred to in clause (i) above or 
any cash dividends) or issue to all holders of its Common Stock rights or 
warrants to subscribe for or purchase any of its securities other than those 
described in clause (v) above, (vii) make a distribution consisting of cash, 
excluding any quarterly cash dividend on the Common Stock to the extent that 
the aggregate cash dividend per Common Share in any quarter does not exceed 
$0.16 (as adjusted to reflect any events described in clauses (ii) and 
(iii)), and excluding any dividend or distribution in connection with the 
liquidation, dissolution or winding up of the Company or (viii) cause the 
Rights (as defined below under "--Preferred Share Purchase Rights") to be 
separated from the Common Shares in accordance with the provisions of the 
Rights Agreement (as defined below) such that holders of New Preferred Stock 
would not be entitled to receive any such Rights in respect of the Common 
Shares issuable upon conversion of such New Preferred Stock. The Company will 
also be entitled to make additional upward adjustments in the Common 
Equivalent Rate, as it in its discretion shall determine to be advisable, so 
that any stock dividends, subdivision of shares, distribution of rights to 
purchase stock or securities, or distribution of securities convertible into 
or exchangeable for stock (or any transaction which could be treated as any 
of the foregoing transactions pursuant to Section 305 of the Internal 


                                       32
<PAGE>

Revenue Code of 1986, as amended) hereafter made by the Company to its 
shareholders will not be taxable. See "--Preferred Share Purchase Rights" for 
additional information on the Rights.
 
    Upon the effectiveness at any time of a merger, consolidation or similar
extraordinary transaction involving the Company that results in the conversion
or exchange of the Common Shares into, or results in the holders of Common
Shares having the right to receive, other securities or other property (an
"Extraordinary Transaction"), each share of New Preferred Stock will be
automatically converted into, or into the right to receive, as the case may be,
securities and other property (including cash) of the same character and in the
same respective amounts as the holder of such share would have received if such
share had been converted pursuant to the optional conversion provisions
described below under "--Optional Conversion" immediately prior to the
effectiveness of such Extraordinary Transaction.
 
   
    The term "Current Market Price" on any date of determination means the
average closing price of a Common Share as reported in the composite quotations
for securities listed on the NYSE for the five consecutive trading days ending
on and including such date of determination; provided, however, that if the
closing price of the Common Shares on the NYSE on the trading day next following
such five-day period (the "next-day closing price") is less than 95% of such
average closing price, then the Current Market Price per Common Share on such
date of determination will be the next-day closing price; and provided, further,
that, with respect to any conversion of the New Preferred Stock, if any
adjustment of the Common Equivalent Rate becomes effective during the period
beginning on the first day of such five-day period and ending on the applicable
conversion date, the Current Market Price as determined pursuant to the
foregoing will be appropriately adjusted to reflect such adjustment.
    
 
OPTIONAL CONVERSION
 
   
    The shares of New Preferred Stock may be converted, at the option of the
Company, at any time on or after December 15, 1998 and prior to the Mandatory
Conversion Date, in whole but not in part, into, for each share so converted (1)
a number of Common Shares equal to the Optional Conversion Price (as defined
below) then in effect plus (2) the right to receive an amount, in cash, equal to
the accrued and unpaid dividends thereon to but excluding the conversion date
plus (3) the right to receive the Optional Conversion Premium (as defined
below).
    
 
    The "Optional Conversion Price" means, for each share of New Preferred Stock
converted at the option of the Company, a number of shares of Common Stock equal
to the lesser of (a) the amount of $        divided by the Current Market Price
as of the close of business on the second trading day immediately preceding the
day on which the Company gives notice of optional conversion and (b) the number
of shares of Common Stock determined by reference to the Common Equivalent Rate
as discussed under "--Mandatory Conversion."
 
    The "Optional Conversion Premium" means, for each share of New Preferred
Stock converted at the option of the Company, an amount, in cash, initially
equal to $20.90, declining by $0.02111 for each day following December 15, 1998
to the optional conversion date (computed on the basis of a 360-day year
consisting of twelve 30-day months) and equal to zero on and after September 15,
2001; provided, however, that in lieu of delivering such amount in cash, the
Company may, at its option, deliver a number of Common Shares equal to the
quotient of such amount divided by the Current Market Price on the second
trading day immediately preceding the day in which the Company gives notice of
such conversion.

    The initial Optional Conversion Premium of $20.90 represents the difference
between the annual dividend of $12.40 on each share of New Preferred Stock and
an assumed annual dividend of $4.80 for ten Common Shares for the period after
December 15, 1998 through September 15, 2001 (i.e. $1.90 per quarter for eleven
quarters). The premium declines to zero on September 15, 2001; no premium will
be paid on or after September 15, 2001. Dividends will accrue on the Preferred
Stock through the conversion date.

PROCEDURES FOR CONVERSION

   
    Notice of any conversion will be sent to the holders of the shares of New
Preferred Stock to be converted not less than 15 days nor more than 60 days
prior to the conversion date; provided, however, that the failure to mail any
such notice of conversion 
                                       33
<PAGE>
 
or any defect therein or in the mailing thereof will not prevent the 
occurrence of such conversion or impair the validity thereof.
    
 
   
    Shares of New Preferred Stock to be converted will, on the date fixed for
conversion, be deemed to have been converted; from and after such conversion
date dividends will cease to accrue on such shares; and all rights of the
holders of such shares (except only rights as holders of securities into which
such shares have been converted and the right to receive certificates
representing such securities and the right to receive an amount, in cash, equal
to dividends accrued on such shares to the date fixed for such conversion plus
any Optional Conversion Premium not otherwise paid in Common Shares) will
terminate.
    
 
    Because the price of the Common Shares is subject to market fluctuations,
the value of the Common Shares received by a holder of shares of New Preferred
Stock upon conversion thereof on the Mandatory Conversion Date or upon an
Extraordinary Transaction of the Company may be more or less than the value of
the Common Shares tendered in exchange therefor. The shares of New Preferred
Stock are not convertible into Common Shares or cash at the option of the
holders thereof.
 
VOTING RIGHTS
 
    Except for those purposes for which the right to vote is expressly conferred
by law or the Restated Articles, the holders of New Preferred Stock have no
power to vote. The holders of the Common Stock have sole voting power, except as
indicated below or as otherwise provided by law, and each holder of Common Stock
is entitled to vote cumulatively for the election of directors.
 
    Under the Restated Articles, whenever and as often as dividends payable on
shares of Preferred Stock (including the New Preferred Stock) shall be in
arrears in an amount equal to the aggregate amount of dividends accumulated on
such shares over the eighteen (18) month period ended on such date, the holders
of Preferred Stock, voting separately and as a single class, shall be entitled
to elect a majority of the Board of Directors, and the holders of the Common
Stock, voting separately and as a single class, shall be entitled to elect the
remaining directors of the Company until such time as all defaults in the
payment of dividends on the Preferred Stock of any and all series shall have
been cured.
 
    In addition, under the Restated Articles the affirmative vote of the holders
of at least a majority of the shares of the Preferred Stock is required:
 
    (a) for the adoption of any amendment of the Restated Articles which would:
(i) create or authorize any new class of stock ranking prior to or on a parity
with the Preferred Stock as to dividends or upon dissolution, liquidation or
winding up; (ii) increase the authorized number of shares of the Preferred
Stock; or (iii) change any of the rights or preferences of the Preferred Stock
at the time outstanding, provided that if any such change would affect the
holders of less than the Preferred Stock of all series then outstanding, only
the affirmative vote of the holders of at least a majority of the shares of all
series so affected is required; and
 
    (b) for the issuance of Preferred Stock, or of any other class of stock 
ranking prior to or on a parity with such Preferred Stock as to dividends or 
upon dissolution, liquidation or winding up, unless the net income of the 
Company available for the payment of dividends for a period of 12 consecutive 
calendar months within the 15 calendar months immediately preceding the 
issuance of such shares is at least equal to one and one-half times the 
annual dividend requirements on shares of Preferred Stock and on all shares 
of all other classes of stock ranking prior to or on a parity with the 
Preferred Stock as to dividends or upon dissolution, liquidation or winding 
up, which will be outstanding immediately after the issuance of such shares, 
including the shares proposed to be issued; PROVIDED, HOWEVER, that if the 
shares of Preferred Stock or any such prior or parity stock shall have a 
variable dividend rate, the annual dividend requirement of such shares shall 
be determined by reference to the weighted average dividend rate on such 
shares during the 12 month period for which the net income of the Company 
available for the payment of dividends shall have been determined; and 
provided, further, that if the shares of the series to be issued are to have 
a variable dividend 

                                       34
<PAGE>

rate, the annual dividend requirement on such shares shall be determined by 
reference to the initial dividend rate upon the issuance of such shares.
 
   
    Under Washington law, a vote of the holders of a majority of the outstanding
shares of Preferred Stock is required in connection with certain changes in the
capital structure of the Company or in certain rights and preferences of the
Preferred Stock, including certain of the changes described in (a) above. In
addition, Washington law requires the approval of certain mergers, share
exchanges and other major corporate transactions by the holders of two-thirds of
the outstanding Preferred Stock.
    
 
    For those purposes for which the Preferred Stock has the right to vote, the
holders are entitled to one vote for each share held. In such a situation, each
RECONS would receive one-tenth of the vote allotted to one share of Preferred
Stock. Votes may be cumulated in electing directors.
 
CLASSIFIED BOARD OF DIRECTORS
 
    Both the Restated Articles and the Bylaws provide for a Board of Directors
divided into three classes, each of which will generally serve for a term of
three years, with only one class of directors being elected in each year. The
Restated Articles and Bylaws also provide that directors may be removed only for
cause and only by the affirmative vote of the holders of a least a majority of
the Common Stock. The Restated Articles and Bylaws further require an
affirmative vote of the holders of at least 80% of the Common Stock to alter,
amend or repeal the provisions relating to the classification of the Board of
Directors and the removal of members from, and the filling of vacancies on, the
Board of Directors.
 
CHANGE IN CONTROL
 
    The Restated Articles contain a "fair price" provision which requires the
affirmative vote of the holders of at least 80% of the Common Stock for the
consummation of certain business combinations, including mergers,
consolidations, recapitalizations, certain dispositions of assets, certain
issuances of securities, liquidations and dissolutions involving the Company and
a person or entity who is or, under certain circumstances, was, a beneficial
owner of 10% or more of the outstanding shares of Common Stock (an "Interested
Shareholder"), unless (a) such business combination shall have been approved by
a majority of the directors unaffiliated with the Interested Shareholder or (b)
certain minimum price and procedural requirements are met. The Restated Articles
provide that the "fair price" provision may be altered, amended or repealed only
by the affirmative vote of the holders of at least 80% of the Common Stock.
 
PREFERRED SHARE PURCHASE RIGHTS
 
   
    Reference is made to the Rights Agreement, dated as of February 16, 1990
(the "Rights Agreement"), between the Company and The Bank of New York, as
successor Rights Agent, filed with the SEC. The following statements are
qualified in their entirety by such reference.
    
 
    The Company has adopted a shareholder rights plan pursuant to which 
holders of Common Stock outstanding on March 2, 1990 or issued thereafter 
have been granted one preferred share purchase right ("Right") on each 
outstanding share of Common Stock. The description and terms of the Rights 
are set forth in the Rights Agreement. Certain of the capitalized terms used 
in the following description have the meanings set forth in the Rights 
Agreement.
 
    Each Right, initially evidenced by and traded with the shares of Common
Stock, entitles the registered holder to purchase one one-hundredth of a share
of Preferred Stock of the Company, without par value (the "Preferred Shares"),
at an exercise price of $80, subject to certain adjustments, regulatory approval
and other specified conditions. The Rights will be exercisable only if a person
or group acquires 10% or more of the outstanding Common Stock or announces a
tender offer, the consummation of which would result in the beneficial ownership
by a person or group of 10% or more of the Common Stock.

 
                                       35
<PAGE>
 
    If any person or group acquires 10% or more of the outstanding Common Stock,
each Right will entitle its holder (other than such person or members of such
group), subject to regulatory approval and other specified conditions, to
purchase that number of shares of Common Stock or Preferred Shares having a
market value of twice the Right's exercise price. In addition, in the event that
any person or group has acquired 10% or more of the outstanding Common Stock or
the Company consolidates or merges with or into, or sells 50% or more of its
assets or earning power to, any person or group, or engages in certain
"self-dealing" transactions with any person or group owning 10% or more of the
outstanding Common Stock, proper provision will be made so that each Right would
thereafter entitle its holder to purchase that number of the acquiring company's
common shares having a market value at that time of twice the Right's exercise
price.
 
    At any time after a person or group acquires more than 10% but less than 50%
of the outstanding Common Stock, the Board of Directors of the Company may,
subject to any necessary regulatory approval, require each outstanding Right to
be exchanged for one share of Common Stock or cash, securities or other assets
having a value equal to the market value of one share of Common Stock.
 
    The Rights may be redeemed, at a redemption price of $.01 per Right, by the
Board of Directors of the Company at any time until any person or group has
acquired 10% or more of the Common Stock. Under certain circumstances, the
decision to redeem the Rights will require the concurrence of a majority of the
Continuing Directors. The Rights will expire on February 16, 2000.
 
    The Rights have certain anti-takeover effects. The Rights may cause
substantial dilution to a person or group that attempts to acquire the Company
on terms not approved by the Company's Board of Directors, except pursuant to an
offer conditioned on a substantial number of Rights being acquired. The Rights
should not interfere with any merger or other business combination approved by
the Board of Directors of the Company prior to the time that a person or group
has acquired beneficial ownership of 10% or more of the Common Stock since until
such time the Rights may be redeemed as described above.
 
PRE-EMPTIVE RIGHTS
 
    No holder of any stock of the Company has any pre-emptive rights.
 
MISCELLANEOUS
 
    There is no specific restriction on the repurchase by the Company of the New
Preferred Stock or Common Stock while there is any arrearage in the payment of
dividends on the New Preferred Stock.
 
    Upon issuance and exchange pursuant to the Exchange Offer as herein
described, the New Preferred Stock will be validly issued, fully paid and
nonassessable, and the holders thereof will not be subject to liability for
further calls or assessment by the Company.
 
    The presently outstanding shares of Common Stock of the Company are fully
paid and nonassessable, and the shares of Common Stock to be issued upon
conversion of the Preferred Stock, as herein described, will be fully paid and
nonassessable.

             CERTAIN UNITED STATES FEDERAL INCOME TAX CONSEQUENCES
 
    The following discussion describes certain United States federal income tax
consequences that may be expected to result from (i) an exchange of Common
Shares pursuant to the Exchange Offer, and (ii) the ownership and disposition of
RECONS and New Preferred Stock. The discussion contained in this summary is
based on the Internal Revenue Code of 1986, as amended (the "Code"), existing
and proposed Treasury Regulations, judicial decisions and administrative
pronouncements, all of which are subject to change. Any such changes may be
applied retroactively in a manner that could cause the tax consequences to vary
substantially from the consequences described below, with possible adverse
effects.
 
    This summary discusses only Common Shares, RECONS and New Preferred Stock
held by United States Holders (as defined below) as capital assets within the
meaning of Section 1212 of the Code. The tax treatment of a holder may vary
depending on such holder's particular situation. This summary does not deal with
all tax consequences that may be relevant to all categories of holders such as
banks, thrift institutions, real estate investment trusts, regulated investment
companies, insurance companies, dealers in securities or commodities, tax-exempt
investors, certain U.S. expatriates, holders whose "functional currency" is not
the U.S. dollar, or persons who hold Common Shares, RECONS or New Preferred
Stock as a position in a straddle, as part of a synthetic security or hedge, as
part of a conversion transaction or other integrated investment, or as other
than a capital asset, or holders who are not United States Holders (as defined
below). Moreover, the summary may not be applicable to holders who received
their Common Shares pursuant to the exercise of employee stock options or
otherwise as compensation or to Common Shares held by the Company's employee
benefit plans. Further, the summary does not include any description of any
alternative minimum tax consequences or any state, local or foreign tax
consequences that may be applicable.
 
    The following discussion is based upon the views of Thelen Reid & Priest
LLP. No statutory, administrative or judicial authority directly addresses the
tax treatment of RECONS or New Preferred Stock. As a result, significant aspects
of the United States federal income tax consequences of an investment in the
RECONS are not certain. No ruling is being requested from the Internal Revenue
Service ("IRS") with respect to the RECONS, and no assurance can be given that
the Internal Revenue Service will agree with the tax consequences described
herein. HOLDERS OF COMMON SHARES ARE URGED TO CONSULT THEIR TAX ADVISORS WITH
RESPECT TO THE TAX CONSEQUENCES TO THEM OF THE EXCHANGE OFFER AND THE OWNERSHIP
AND DISPOSITION OF THE RECONS OR NEW PREFERRED STOCK IN LIGHT OF THEIR
PARTICULAR CIRCUMSTANCES, INCLUDING THE TAX CONSEQUENCES UNDER STATE, LOCAL,
FOREIGN AND OTHER TAX LAWS, AND THE POSSIBLE EFFECTS OF CHANGES IN UNITED STATES
FEDERAL OR OTHER TAX LAWS.
 
    As used herein, a "United States Holder" means a beneficial owner of Common
Shares, RECONS or New Preferred Stock, as the case may be, that is (i) a citizen
or resident of the United States, (ii) a corporation, partnership or other
entity created or organized in or under the laws of the United States or any
State thereof or the District of Columbia, (iii) an estate the income of which
is subject to United States federal income taxation regardless of its source, or
(iv) a trust the administration of which is subject to the primary supervision
of a court within the United States and for which one or more U.S. persons have
the authority to control all substantial decisions. An individual may, subject
to certain exceptions, be deemed to be a resident (as opposed to a non-resident
alien) of the United States by virtue of being present in the United States on
at least 31 days in the calendar year and for an aggregate of at least 183 days
during a three-year period ending in the current calendar year (counting for
such purposes all of the days present in the current year, one-third of the days
present in the immediately preceding year, and one-sixth of the days present in
the second preceding year).

CHARACTERIZATION OF THE EXCHANGE OFFER
 
    The Company has received an opinion of Thelen Reid & Priest LLP, as tax
counsel, that the exchange of Common Shares for RECONS or New Preferred Stock
should be treated as a "recapitalization" pursuant to section 368(a)(1)(E) of
the Code. In that event, the transaction will have the tax consequences to
shareholders set forth below.

                                       37
<PAGE>

 
EXCHANGE OF COMMON SHARES PURSUANT TO THE EXCHANGE OFFER
 
EXCHANGE OF COMMON SHARES FOR RECONS
 
    Based upon the view that the New Preferred Stock is not classified as
"nonqualified preferred stock" within the meaning of Code section 351(g)(2), as
described below, no gain or loss will be recognized by an exchanging shareholder
on the exchange. A United States Holder's tax basis in the RECONS received in
the exchange will be equal to such holder's tax basis in the Common Shares
exchanged therefor, and the holding period of such RECONS will include the
holding period of such Common Shares.
 
CLASSIFICATION OF NEW PREFERRED STOCK AS "NONQUALIFIED PREFERRED STOCK"
 
    The nonrecognition rule described in the preceding paragraph will not apply,
and gain or loss will be recognized upon the exchange of Common Shares for New
Preferred Shares, if the New Preferred Shares are classified as "nonqualified
preferred stock" within the meaning of Code section 351(g)(2). For these
purposes, the term "nonqualified preferred stock" means preferred stock if (i)
the holder of such stock has the right to require the issuer or a related person
to redeem or purchase the stock, (ii) the issuer or a related person is required
to redeem or purchase such stock, (iii) the issuer or a related person has the
right to redeem or purchase the stock and, as of the issue date, it is more
likely than not that such right will be exercised, or (iv) the dividend rate on
such stock varies in whole or in part (directly or indirectly) with reference to
interest rates, commodity prices, or other similar indices.
 
    Code section 351(g)(2) was added to the Code pursuant to the Taxpayer Relief
Act of 1997 and, to date, little authority has been issued regarding the scope
of this provision. It is unclear whether the New Preferred Stock will be treated
as preferred stock for purposes of Code section 351(g). For this purpose,
"preferred stock" is defined as stock which is limited and preferred as to
dividends and does not participate in corporate growth to any significant
extent. The New Preferred Stock will participate in future appreciation in the
value of Common Shares up to $[ ] per share. Assuming that the New Preferred
Stock is treated as preferred stock for those purposes, certain terms of the New
Preferred Shares raise the concern that such shares would fall within the
definition of "nonqualified preferred stock." However, the legislative history
underlying the enactment of this provision indicates that the nonrecognition
reorganization provisions of the Code are not to apply where a common
shareholder exchanges that stock for a more secure equity investment in the
issuer. Since, inter alia, the holders of the New Preferred Stock will not be
protected from any decrease in the trading price of the Common Shares into which
the New Preferred Stock is convertible, the New Preferred Stock should not be
classified as "nonqualified preferred stock" within the meaning of Code section
351(g)(2).
 
OWNERSHIP AND DISPOSITION OF RECONS AND NEW PREFERRED STOCK
 
RECONS
 
    The tax treatment of United States Holders of RECONS will be the same as 
the tax treatment of United States Holders of New Preferred Stock as 
described below. In addition, a United States Holder will recognize no gain 
or loss on the withdrawal of New Preferred Stock in exchange for RECONS 
pursuant to the Deposit Agreement; the United States Holder's tax basis in 
the withdrawn New Preferred Stock will be the same as such Holder's tax basis 
in the RECONS surrendered therefor; and the United States Holder's holding 
period for the withdrawn New Preferred Stock will include the period during 
which such Holder held the surrendered RECONS.
 
DIVIDENDS
 
    Dividends paid on the New Preferred Stock out of the Company's current or
accumulated earnings and profits will be taxable as ordinary income and will
qualify for the 70% intercorporate dividends-received deduction, subject to the
minimum holding period requirement (generally at least 46 days) and other
applicable requirements. The dividends-received deduction will not be allowed
for purposes of calculating a corporate United States Holder's adjusted current
earnings under the alternative minimum tax rules. To the extent, if any, that
the amount of any dividend paid on the New Preferred Stock exceeds the Company's
current and 
                                       38
<PAGE>

accumulated earnings and profits, it will be treated first as a return of the 
United States Holder's tax basis in the New Preferred Stock and thereafter as 
a capital gain.
 
    Under certain circumstances, a corporation that receives an "extraordinary
dividend," as defined in Section 1059(c) of the Code, is required to reduce the
tax basis of its stock by the non-taxed portion of such dividend. A corporate
United States Holder must consider its holding period for, its tax basis in, and
the fair market value of, the New Preferred Stock in determining whether
dividends paid on the New Preferred Stock will constitute "extraordinary
dividends." In addition, under Section 1059(f) of the Code, any dividend with
respect to "disqualified preferred stock" is treated as an "extraordinary
dividend." While the issue is not free from doubt due to the lack of authority
directly on point, the New Preferred Stock should not constitute "disqualified
preferred stock."
 
CONSTRUCTIVE DISTRIBUTION RISKS
 
    Under certain circumstances, Section 305(c) of the Code requires that any
excess of the redemption price of preferred stock over its issue price be
includible in income, prior to receipt, as a constructive dividend. However,
while the issue is not free from doubt due to the lack of authority directly on
point, since, inter alia, the New Preferred Stock bears risk with respect to a
decline in the value of Common Shares, and therefore its redemption price is not
truly fixed, Section 305(c) should not currently apply to stock with terms such
as those of the New Preferred Stock.
 
    Certain adjustments to the conversion rate for the New Preferred Stock to
reflect the Company's issuance of stock or warrants to holders of Common Shares
(or similar transactions) may result in constructive distributions taxable as
dividends to the United States Holders of the New Preferred Stock. The
antidilution formula for the New Preferred Stock is intended to adjust the
conversion ratio to reflect these types of distributions in a manner to qualify
under Code section 305(c) and should not result in constructive distributions to
holders of New Preferred Stock.
 
    A constructive distribution may result where preferred stock with dividends
in arrears is exchanged for other stock and, as a result, a holder of the
preferred stock increases his proportionate interest in the assets or earnings
and profits of the corporation. This provision is designed to prevent the
capitalization of dividends into stock on a tax free basis. Since cash will be
paid with respect to accrued unpaid dividends upon a conversion of the New
Preferred Stock, this provision should not apply.
 
    Any constructive dividend may constitute, and may cause other dividends to
constitute, "extraordinary dividends" to corporate United States Holders. See
"Dividends" above.
 
CONVERSION OF NEW PREFERRED STOCK INTO COMMON SHARES AND CASH
 
    Gain or loss generally will not be recognized by a United States Holder 
upon the conversion of the New Preferred Stock solely into Common Shares. 
Gain realized by a United States Holder upon the conversion of the New 
Preferred Stock into Common Shares and cash will be recognized to the extent 
of the cash received (including any Option Conversion Premium which is paid 
in cash and any cash received in payment of accrued unpaid and undeclared 
dividends, but excluding any cash received in lieu of a fractional share). 
Such taxable gain will be treated either as capital gain or as a dividend, 
depending on such Holder's particular circumstances, as described in the 
following paragraphs. No loss will be recognized upon the conversion of the 
New Preferred Stock into Common Shares and cash.
 
    In testing whether gain recognized upon the conversion of the New Preferred
Stock into Common Shares and cash (other than cash in lieu of fractional Common
Shares) will be treated as capital gain or as a dividend, the United States
Holder will be treated as if such holder received Common Shares with a value
equal to such cash, and then such deemed Common Shares were redeemed by the
Company for such cash. Such gain will be treated as capital gain if, inter alia,
such deemed redemption would be a "substantially disproportionate" redemption
with respect to such Holder or is "not essentially equivalent to a dividend"
with respect to the Holder. An exchange of Common Shares for cash will be "not
essentially equivalent to a dividend" if it results in a "meaningful reduction"
of the United States Holder's equity interest in the Company. An exchange of
Common Shares for cash that results in a reduction of the proportionate equity
interest in the Company of a United States Holder whose relative equity interest
in the Company is minimal (an interest of less than one percent should satisfy
this requirement) and who exercises  

                                       39
<PAGE>

no control over the Company's corporate affairs should be treated as "not 
essentially equivalent to a dividend." If the deemed redemption would be 
treated as a dividend under Code section 302, then the gain recognized will 
be taxed as a dividend. However, notwithstanding the foregoing, the IRS may 
take the position that cash paid with respect to accrued unpaid dividends 
will be treated as dividends in all events. United States Holders should 
consult their own tax advisors about the application of these rules in their 
particular circumstances.
 
    Cash received by a United States Holder in lieu of a fractional share will
be treated as if such holder received a fractional Common Share with a value
equal to such cash, and then such deemed fractional Common Share were redeemed
by the Company for such cash. Any resulting gain or loss should be treated as
capital gain or loss.
 
    A United States Holder's tax basis in the Common Shares, including any
fractional share, received on the conversion of the New Preferred Stock will
equal the tax basis of the New Preferred Stock surrendered in exchange therefor,
reduced by the amount of cash received and increased by the amount of income or
gain recognized. The holding period of such Common Shares will include the
holding period of the New Preferred Stock surrendered in exchange therefor.
 
OTHER DISPOSITIONS OF NEW PREFERRED STOCK
 
    A United States Holder will generally recognize gain or loss on a sale,
exchange or other disposition of New Preferred Stock in an amount equal to the
difference between the amount realized on the sale, exchange or other
disposition and such Holder's tax basis in the New Preferred Stock. Any such
gain or loss will be capital gain or loss and will be long-term capital gain or
loss if the holding period of the New Preferred Stock exceeds one year as of the
date of the disposition.
 
    Under certain circumstances, upon the taxable disposition or taxable
redemption of "section 306 stock," the holder of such stock is required to
recognize as ordinary income, in the case of a disposition, or as dividend
income, in the case of a redemption, all or a portion of the proceeds received
by such holder, without regard to such holder's tax basis in the "section 306
stock," and cannot recognize any loss. To the extent that a United States Holder
that exchanges Common Shares for New Preferred Stock would have been treated,
under the rules of Section 302 of the Code, as receiving a dividend distribution
from the Company if such Holder had tendered such Common Shares for cash, the
New Preferred Stock owned by such United States Holder may be treated as
"section 306 stock." United States Holders should consult their tax advisors
concerning the consequences of the Exchange Offer under Section 306 of the Code.

NON-PARTICIPATION IN THE EXCHANGE OFFER
 
RETENTION OF COMMON SHARES
 
    Subject to the discussion in the immediately following paragraphs, United
States Holders of Common Stock who do not participate in the Exchange Offer
should not incur any tax liability as a result of the consummation of the
Exchange Offer.
 
CONSTRUCTIVE DISTRIBUTION RISKS
 
    Under section 305(c) of the Code, a recapitalization or a redemption (such
as exchanges pursuant to the Exchange Offer or any future conversion of RECONS
or New Preferred Stock) may, under certain limited circumstances, be deemed to
be a taxable distribution of stock with respect to any other shareholder whose
proportionate interest in the assets or earnings and profits of the corporation
is increased as a result. Exchanges pursuant to the Exchange Offer and any
subsequent conversion of any RECONS or New Preferred Stock may have the effect
of increasing the proportionate interests in the assets or earnings and profits
of the Company of the holders of Common Shares who do not participate in the
Exchange Offer. However, neither an exchange pursuant to the Exchange Offer nor
a subsequent conversion of RECONS or New Preferred Stock should result in any
deemed taxable distribution of stock to the United States Holders of the Common
Shares because such exchange or subsequent conversion should be treated as an
isolated recapitalization and not as part of a plan periodically to increase the
proportionate interest of holders of Common Shares in the Company's assets or
earnings and profits and because there is no certainty that the interest of the
holders of Common Shares would in fact be increased upon the Exchange Offer or
any subsequent conversion of RECONS.


                                       40

    Under section 305(b)(2) of the Code, a distribution which has the result of
the receipt of property by some shareholders (such as distributions on the New
Preferred Stock) and an increase in the proportionate interests of other
shareholders in the assets or earnings and profits of the corporation may, under
certain limited circumstances, be deemed to be a taxable distribution of stock
with respect to the other shareholders whose interests in the assets or earnings
and profits of the corporation are increased. It is believed that distributions
on the New Preferred Stock should not have the effect of increasing the
proportionate interests of the holders of the Common Shares in the assets or
earnings and profits of the Company because such distributions will only result
in adjustments to the Optional Conversion Premium which is designed to deliver a
specific value to holders of New Preferred Stock in lieu of future dividends and
such premium (payable in cash or Common Shares, at the option of the Company)
will be payable only if the Company exercises its right to effect an optional
conversion. As such, distributions on the New Preferred Stock should not result
in any deemed taxable distribution of stock to the holders of the Common Shares
pursuant to Code section 305(b)(2).
 
    The failure to adjust fully the conversion rate of the New Preferred Stock
to reflect distributions of stock dividends (or rights to acquire stock) with
respect to the Common Shares (or transactions having the effect of such
distributions) may result in a taxable dividend to the holders of the Common
Shares. The antidilution formula for the New Preferred Stock is intended to
adjust the conversion ratio to reflect distributions of stock dividends or
similar transactions in a manner to qualify under Code section 305(c) and should
not result in constructive distributions to holders of Common Shares.
 
    Any constructive dividend may constitute, and may cause other dividends to
constitute, "extraordinary dividends" to corporate United States Holders. See
"--Dividends" above.
 
INFORMATION REPORTING AND BACKUP WITHHOLDING
 
    In general, information reporting requirements will apply to payments of
dividends and the proceeds of sales of the New Preferred Stock made to United
States Holders other than certain exempt recipients (such as corporations). A
31% backup withholding tax will apply to such payments if the United States
Holder (i) fails to provide a taxpayer identification number ("TIN"), (ii)
furnishes an incorrect TIN, (iii) is notified by the IRS that it has failed to
properly report payments of interest and dividends, or (iv) under certain
circumstances, fails to certify, under penalty of perjury, that it has furnished
a correct TIN and has not been notified by the IRS that it is subject to backup
withholding. In the case of dividends paid after December 31, 1999, a United
States Holder generally will be subject to backup withholding at a 31% rate
unless certain IRS certification procedures are complied with directly or
through an intermediary.
 
    Any amounts withheld under the backup withholding rules will be allowed as a
refund or credit against such United States Holder's U.S. federal income tax
liability provided the required information is furnished to the IRS.

   
    THE DESCRIPTION OF FEDERAL INCOME TAX CONSEQUENCES SET FORTH ABOVE IS FOR
GENERAL INFORMATION PURPOSES ONLY. THE COMPANY DOES NOT INTEND TO SEEK A RULING
FROM THE INTERNAL REVENUE SERVICE WITH RESPECT TO THE FEDERAL INCOME TAX
CONSEQUENCES OF THE EXCHANGE OFFER OR THE OWNERSHIP OR DISPOSITION OF THE NEW
PREFERRED STOCK AND, UPON EXAMINATION OF THE INCOME TAX RETURN OF THE COMPANY OR
A SHAREHOLDER, THE INTERNAL REVENUE SERVICE MAY TAKE POSITIONS CONTRARY TO THOSE
SET FORTH HEREIN. ALL SHAREHOLDERS SHOULD CONSULT THEIR OWN TAX ADVISORS AS TO
THE PARTICULAR TAX CONSEQUENCES TO THEM OF THE EXCHANGE OFFER AND OF THE
OWNERSHIP AND SUBSEQUENT DISPOSITION OF THE NEW PREFERRED STOCK, INCLUDING THE
APPLICABILITY OF STATE, LOCAL AND FOREIGN TAX LAWS.

                                    PART II
 
ITEM 20. INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
    Article Seventh of the Company's Restated Articles of Incorporation
("Articles") provides, in part, as follows:
 
    "The Corporation shall, to the full extent permitted by applicable law, as
from time to time in effect, indemnify any person made a party to, or otherwise
involved in, any proceeding by reason of the fact that he or she is or was a
director of the Corporation against judgments, penalties, fines, settlements and
reasonable expenses actually incurred by him or her in connection with any such
proceeding. The Corporation shall pay any reasonable expenses incurred by a
director in connection with any such proceeding in advance of the final
determination thereof upon receipt from such director of such undertakings for
repayment as may be required by applicable law and a written affirmation by such
director that he or she has met the standard of conduct necessary for
indemnification, but without any prior determination, which would otherwise be
required by Washington law, that such standard of conduct has been met. The
Corporation may enter into agreements with each director obligating the
Corporation to make such indemnification and advances of expenses as are
contemplated herein. Notwithstanding the foregoing, the Corporation shall not
make any indemnification or advance which is prohibited by applicable law. The
rights to indemnity and advancement of expenses granted herein shall continue as
to any person who has ceased to be a director and shall inure to the benefit of
the heirs, executors and administrators of such a person."
 
    The Company has entered into indemnification agreements with each director
as contemplated in Article Seventh of the Articles.
 
    Reference is made to Revised Code of Washington 23B.08.510, which sets forth
the extent to which indemnification is permitted under the laws of the State of
Washington.
 
    Article IX of the Company's Bylaws contains an indemnification provision
similar to that contained in the Articles and, in addition, provides in part as
follows:
 
    "SECTION 2. LIABILITY INSURANCE. The Corporation shall have the power to
purchase and maintain insurance on behalf of any person who is, or was a
director, officer, employee, or agent of the Corporation or is or was serving at
the request of the Corporation as a director, officer, employee or agent of
another corporation, partnership, joint venture, trust, other enterprise, or
employee benefit plan against any liability asserted against him and incurred by
him in any such capacity or arising out of his status as such, whether or not
the Corporation would have the power to indemnify him against such liability
under the laws of the State of Washington."
 
    Insurance is maintained on a regular basis (and not specifically in
connection with this offering) against liabilities arising on the part of
directors and officers out of their performance in such capacities or arising on
the part of the Company out of its foregoing indemnification provisions, subject
to certain exclusions and to the policy limits.
 
ITEM 21. EXHIBITS.
 
    Reference is made to the Exhibit Index on page II-5 hereof.
 
ITEM 22. UNDERTAKINGS.
 
    The undersigned registrant hereby undertakes:
 
   
        (1) To file, during any period in which offers or sales are being made,
    a post-effective amendment to this registration statement:
    
 
                                      II-1
<PAGE>
   
            (i) To include any prospectus required by Section 10(a)(3) of the
       Securities Act of 1933, as amended (the "Securities Act");
    
 
   
            (ii) To reflect in the prospectus any facts or events arising after
       the effective date of the registration statement (or the most recent
       post-effective amendment thereof) which, individually or in the
       aggregate, represent a fundamental change in the information set forth in
       the registration statement; and
    
 
   
           (iii) To include any material information with respect to the plan of
       distribution not previously disclosed in the registration statement or
       any material change to such information in this registration statement;
    
 
   
        (2) That, for the purpose of determining any liability under the
    Securities Act, each such post-effective amendment shall be deemed to be a
    new registration statement relating to the securities offered herein, and
    the offering of such securities at that time shall be deemed to be the
    initial bona fide offering thereof;
    
 
   
        (3) To remove from registration by means of a post-effective amendment
    any of the securities being registered which remain unsold at the
    termination of the offering;
    
 
   
        (4) That, for purposes of determining any liability under the Securities
    Act, each filing of the registrant's annual report pursuant to Section 13(a)
    or 15(d) of the Exchange Act (and, where applicable, each filing of an
    employee benefit plan's annual report pursuant to Section 15(d) of the
    Exchange Act) that is incorporated by reference in this registration
    statement shall be deemed to be a new registration statement relating to the
    securities offered herein, and the offering of such securities at that time
    shall be deemed to be the initial bona fide offering thereof; and
    
 
   
        (5) To respond to requests for information that is incorporated by
    reference into the prospectus pursuant to Items 4, 10(b), 11, or 13 of Form
    S-4, within one business day of receipt of such request, and to send the
    incorporated documents by first class mail or other equally prompt means.
    This includes information contained in documents filed subsequent to the
    effective date of the registration statement through the date of responding
    to the request.
    
 
    Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers and controlling persons of the
registrant pursuant to the foregoing provisions, or otherwise, the registrant
have been advised that in the opinion of the Commission such indemnification is
against public policy as expressed in the Securities Act and is, therefore,
unenforceable. In the event that a claim for indemnification against such
liabilities (other than the payment by the registrant of expenses incurred or
paid by a director, officer or controlling person of the registrant in the
successful defense of any action, suit or proceeding) is asserted against either
of the registrant by such director, officer or controlling person in connection
with the securities being registered, such registrant will, unless in the
opinion of its counsel the matter has been settled by controlling precedent,
submit to a court of appropriate jurisdiction the question whether such
indemnification by it is against public policy as expressed in the Securities
Act and will be governed by the final adjudication of such issue.

                          DEALER MANAGER AGREEMENT

                                                  ________ __, 1998

J.P. Morgan Securities Inc.
60 Wall Street
New York, New York 10260

Dear Sirs:

     1.   OFFER TO EXCHANGE.  The Washington Water Power Company, a 
Washington corporation (the "Company"), plans to make an exchange offer to 
exchange up to 20,000,000 shares of its outstanding Common Stock, no par 
value (collectively, the "Original Securities") for Depositary Shares (the 
"Return Enhanced Convertible Shares" or "RECONS"), each constituting a 1/10th 
interest in one share of new series of Preferred Stock of the Company to be 
designated the $12.40 Cumulative Preferred Stock, Convertible Series L (the 
"New Preferred Stock") (the RECONS and the Preferred Stock are collectively 
referred to in this Agreement as the "New Securities") on the terms and 
subject to the conditions to be set forth in the Exchange Offer Prospectus 
relating to the New Securities and the accompanying letters of transmittal 
(each, a "Letter of Transmittal"). The RECONS will be evidenced by depositary 
receipts ("Receipts") to be issued by The Bank of New York, as Depositary 
(the "Depositary") under a Deposit Agreement, to be dated as of 
[__________________], 1998 (the "Deposit Agreement"), between the Company and 
the Depositary.  The offer to exchange the Original Securities on the terms 
and subject to the conditions set forth in the Exchange Offer Prospectus and 
the related Letters of Transmittal (including the solicitation of tenders 
with respect to the Original Securities) is referred to as the "Exchange 
Offer".

     The New Securities will be convertible into shares of common stock, no 
par value, of the Company (the "Common Stock"), in accordance with the terms 
of the Articles of Amendment (the "Articles") to the Company's Restated 
Articles of Incorporation establishing the New Preferred Stock.

     The Company has prepared and filed with the Securities and Exchange 
Commission (the "Commission") in accordance with the provisions of the 
Securities Act of 1933, as amended, and the rules and regulations of the 
Commission thereunder (collectively, the "Securities Act"), a registration 
statement on Form S-4, including a prospectus relating to the New Securities. 
The registration statement as amended at the time when it shall become 
effective, or, if a post-effective amendment is filed with respect thereto, 
as amended by such 

<PAGE>

post-effective amendment at the time of its effectiveness, is referred to in 
this Agreement as the "Registration Statement", and the prospectus included 
therein at the time the Registration Statement (or such post-effective 
amendment) is declared effective is referred to in this Agreement as the 
"Exchange Offer Prospectus."  Any reference in this Agreement to the 
Registration Statement, any preliminary exchange offer prospectus or the 
Exchange Offer Prospectus shall be deemed to refer to and include the 
documents incorporated by reference therein pursuant to the relevant 
provisions of Form S-4 under the Securities Act, as of the effective date of 
the Registration Statement or the date of such preliminary exchange offer 
prospectus or the Exchange Offer Prospectus, as the case may be, and any 
reference to "amend," "amendment" or "supplement" with respect to the 
Registration Statement, any preliminary exchange offer prospectus or the 
Exchange Offer Prospectus shall be deemed to refer to and include any 
documents filed after such date under the Securities Exchange Act of 1934, as 
amended, and the rules and regulations of the Commission thereunder 
(collectively, the "Exchange Act") that are deemed to be incorporated by 
reference therein.

     The Company has also prepared and filed with the Commission an Issuer 
Tender Offer Statement on Schedule 13E-4 (as amended, supplemented or 
modified at any time, and together with the exhibits thereto, the "Schedule 
13E-4") pursuant to the Exchange Act.

     2.   APPOINTMENT OF DEALER MANAGER.  The Company hereby appoints you as 
exclusive Dealer Manager, and authorizes you to act as such, in connection 
with the Exchange Offer. As Dealer Manager, you agree, in accordance with 
your customary practice, to perform those services in connection with the 
Exchange Offer as are customarily performed by investment banking concerns in 
connection with exchange offers of like nature, including but not limited to 
assisting the Company in communicating the terms of the Exchange Offer and 
the mailing of the Exchange Offer Prospectus, the related Letters of 
Transmittal and other related documents to the holders of the Original 
Securities (the "Holders") in conjunction with Morrow & Co. Inc. (the 
"Information Agent") and The Bank of New York (the "Exchange Agent").  You 
shall act as an independent contractor in connection with the Exchange Offer 
with duties solely to the Company, and nothing herein contained shall 
constitute you as an agent of the Company in connection with the solicitation 
of Original Securities pursuant to and in accordance with the terms and 
conditions of the Exchange Offer; PROVIDED that the Company hereby authorizes 
you, and/or one or more registered brokers or dealers chosen by you, to act 
as the Company's agent in making the Exchange Offer to residents of any 
jurisdiction in which such agent's designation may be necessary to comply 
with applicable law.  Nothing in this Agreement shall constitute you as a 
partner of or member of a joint venture with the Company or any of its 
subsidiaries.

                                       2

     3.   COMPENSATION.  The Company has previously agreed in an engagement 
letter with you dated July 20, 1998 (the "Engagement Letter") to pay you 
certain fees in connection with your providing certain financial advisory 
services and the Dealer Manager services described herein, and the terms of 
the Engagement Letter regarding compensation for such services are

any other person for any act or omission on the part of any broker or dealer 
in securities (each, a "Dealer") (other than yourself) or any bank or trust 
company or any other person.  In soliciting or obtaining tenders, no Dealer, 
bank or trust company is to be deemed to be acting as your agent or the agent 
of the Company, and you, as Dealer Manager, are not deemed the agent of the 
Company, any Dealer, bank or trust company or any other person.

     5.   EXPENSES. In addition to your compensation for your services as 
Dealer Manager, the Company agrees to pay (i) all fees and expenses relating 
to the preparation, filing, printing, mailing and publishing of the Exchange 
Offer Material (as defined in Section 6), (ii) all fees and expenses incident 
to the preparation, issuance, execution and delivery of the New Securities, 
(iii) the cost of printing or producing any Blue Sky or Legal Investment 
memorandum in connection with the offer and exchange of the New Securities 
under state securities laws and all costs and expenses incurred in connection 
with the registration or qualification of the New Securities under the laws 
of such jurisdictions as you reasonably may designate, including filing fees 
and the fees and disbursements of your counsel in connection with such 
qualification and in connection with the preparation of any Blue Sky or Legal 
Investment memorandum, (iv) the fees, if any, of the New York Stock Exchange, 
Inc. or any other stock exchange in connection with the listing of the 
RECONS, (v) all fees and expenses of the Depositary, the Information Agent 
and the Exchange Agent appointed, or other persons rendering services, in 
connection with the Exchange Offer, (vi) all advertising charges approved by 
the Company, (vii) all customary mailing and handling fees and expenses of 
any Dealers, banks and trust companies in forwarding the Exchange Offer 
Material to their customers and (viii) all other fees and expenses in

for all reasonable fees and disbursements of your legal counsel as set forth 
in the Engagement Letter, and the terms of the Engagement Letter regarding 
reimbursement of expenses are incorporated by reference herein. All payments 
to be made by the Company pursuant to this Section shall be due as such 
expenses are incurred.  The Company shall perform its obligations set forth 
in this Section whether or not the Exchange Offer is

                                       3

<PAGE>

commenced or any Original Securities are exchanged for New Securities 
pursuant to the Exchange Offer.

     6.   GENERAL AGREEMENTS. The Company authorizes you to use, and agrees 
to furnish you with as many copies as you may reasonably request of, each of 
the Exchange Offer Prospectus and the related letter of the Dealer Manager to 
brokers, dealers and other nominees, the letter to clients, the Letters of 
Transmittal, the notice of guaranteed delivery, the Registration Statement, 
the Schedule 13E-4, newspaper announcements, press releases and any other 
offering documents or materials prepared by the Company for use in connection 
with the Exchange Offer, and all exhibits, amendments or supplements thereto 
(collectively, as amended or supplemented from time to time, the "Exchange 
Offer Material"), without any responsibility for independent verification on 
your part.

     The Exchange Offer Material has been or will be prepared and approved 
by, and is the sole responsibility of, the Company.  The Company shall, to 
the extent permitted by law, use its best efforts to disseminate the Exchange 
Offer Material to each registered Holder as soon as practicable after the 
Commencement Date (as defined in Section 7), pursuant to Rule 13e-4 under the 
Exchange Act, and shall comply with its obligations thereunder.  You shall 
not have any obligation to cause any Exchange Offer Material to be 
transmitted generally to the Holders.  The Company agrees that any reference 
to the Dealer Manager in any Exchange Offer Material or in any newspaper 
announcement or press release or other document or communication is subject 
to your prior consent.

     Prior to and during the period of the Exchange Offer, the Company will 
inform you promptly after any senior executive officer, senior accounting or 
legal officer or treasurer of the Company receives notice or becomes aware of 
the happening of any event, or the discovery of any fact, which such person 
believes would require the making of any change in any Exchange Offer 
Material then being used or would affect the truth or completeness of any 
representation or warranty contained in this Agreement if such representation 
or warranty were being made immediately after the happening of such event or 
the discovery of such fact.

     The Company will provide you with copies of the Company's records 
showing the names and addresses of, and the numbers of Original Securities 
held by, the Holders as of a recent date, and will use its reasonable efforts 
to advise you from day to day during the period of the Exchange Offer as to 
any transfers of record of the Original Securities.  The Company will advise 
you during each business day of all Original Securities tendered for exchange 
or withdrawn during the preceding business day and the names and addresses 
of, and the number of

                                       4

<PAGE>

Original Securities so tendered for exchange or withdrawn by, each such 
tendering or withdrawing Holder.  The Company will advise you of any 
defective tenders and of all tenders verified to be in proper form.  Not 
later than the opening of business on the day following the Expiration Time 
(as defined in the Exchange Offer Prospectus), the Company will advise you of 
all tendered Original Securities, including the number of Original Securities 
either tendered in proper form, rejected for tender or being processed.

     You are authorized to communicate directly with the Depositary, the
Information Agent and the Exchange Agent (and any other information agent or
exchange agent designated or retained by the Company) with respect to matters
relating to the Exchange Offer.

     The Company will arrange for The Bank of New York to serve as Exchange
Agent in connection with the Offer and, as such, to advise you at least daily as
to such matters relating to the Exchange Offer as you may request.

     You and your affiliates may continue at any time to own or trade securities
of the Company or its subsidiaries (including the Original Securities) for your
or their account or the account of others.

     7.   REPRESENTATIONS OF ISSUER. The Company represents and warrants to you

Date") and at all times on or prior to the date of acceptance for exchange of

     the applicable effective date as to the Registration Statement and any
     amendment thereto and as of the date of the Exchange Offer Prospectus and

<PAGE>

Ladies and Gentlemen:

          This opinion is being delivered to you at the request of The
Washington Water Power Company, a Washington corporation (the "Company"), as
contemplated by Section 9(a) of the Dealer Manager Agreement, dated October __,
1998 (the "Dealer Manager Agreement"), between you and the Company relating to
the proposed issuance by the Company of up to 2,000,000  shares of a new series
of the Company's Preferred Stock, no par value, to be designated Preferred
Stock, Convertible Series L (the "New Preferred Stocks").  As contemplated in
the Dealer Manager Agreement, (a) the New Preferred Stock is to be issued and
delivered to The Bank of New York, as depositary (the "Depositary") under a
deposit agreement, to be dated as of _________, 1998 (the "Deposit Agreement"),
(b) up to 20,000,000 depositary shares, each constituting a one-tenth interest
in one share of New Preferred Stock (the "Depositary Shares"), will be offered
to holders of the Company's Common Stock, no par value (the "Common Stock"), in
exchange for outstanding shares of Common Stock on a one-for-one basis (the
"Exchange Offer"), and depositary receipts ("Depositary Receipts") will be
delivered to tendering shareholders to evidence Depositary Shares, and (c) the
New Preferred Stock will be convertible into Common Stock, the Common Stock to
be issued and delivered upon such conversion being hereinafter called the "New
Common Stock".  Capitalized terms used herein but


<PAGE>



not otherwise defined herein shall have the meaning ascribed to them in the 
Dealer Manager Agreement.

          The Company has filed with the Securities and Exchange Commission (the
"SEC") under the Securities Act of 1933, as amended (the "1933 Act"), a
registration statement on Form S-4 (Registration No. 333-61599) for the
registration under the 1933 Act of (a) the New Preferred Stock, (b) the
Depositary Shares and (c) the New Common Stock and the Rights (as hereinafter
defined) appurtenant thereto.  Such registration statement, as amended at the
time it became effective (or at the time of effectiveness of any post-effective
amendment), is hereinafter called the "Registration Statement", and the
prospectus contained in the Registration Statement is hereinafter called the
"Prospectus".  As used herein the term "Rights" means the preferred share
purchase rights issued and to be issued under the Rights Agreement, dated as of
February 16, 1990, between the Company and First Chicago Trust Company of New
York, as amended.

          We have examined, or are generally familiar with, the following:
(a) the Restated Articles of Incorporation, as amended, and the Bylaws, as
amended, of the Company; (b) the Engagement Letter and the Dealer Manager
Agreement; (c) the Deposit Agreement; (d) the Registration Statement and (e) the
documents incorporated by reference into the Registration Statement.  We have
also examined such other documents and satisfied ourselves as to such other
matters as we have deemed necessary in order to render this opinion.  We have
not examined the certificates evidencing shares of the New Preferred Stock,
except a specimen thereof.

          As to various questions of fact (but not as to the legal conclusions
contained therein) material to the opinions set forth below, in rendering such
opinions we have relied, with your permission, upon certificates of public
officials, certificates of officers or other employees of the Company,
representations of the Company in the Dealer Manager Agreement, and other oral
or written assurances by officers or other employees of the Company.  We do not
serve as counsel to direct or indirect subsidiaries or affiliates of the
Company, and, as to various questions relating to the activities of such
subsidiaries and affiliates, we have further relied upon certificates of
officers thereof.

          We have assumed, for the purposes of the opinions enumerated below,
the legal conclusions set forth in paragraphs (1)(a) and (b), (2), (3), (4),
(5), (6) and (7) of the opinion of even date herewith rendered to you by Paine,
Hamblen, Coffin, Brooke & Miller LLP.  We have not been engaged by the Company
with respect to the matters so assumed; however, during the course of such
examinations as we have made for the purposes of the opinions enumerated

<PAGE>


below, nothing came to our attention which leads us to believe that such 
assumptions are not correct.

          Based upon the foregoing, and subject to the qualifications set forth
herein, we are of the opinion that:

          (1)  the Deposit Agreement constitutes a valid and binding instrument,
     enforceable against the Company in accordance with its terms, except to the
     extent the enforcement of the Deposit Agreement may be limited by any
     applicable bankruptcy, insolvency, fraudulent conveyance, reorganization,
     moratorium or other laws affecting creditors' rights generally, by general
     principles of equity (whether asserted in an action in equity or at law)
     and by rules of law governing specific performance, injunctive relief,
     foreclosure, receivership and other equitable remedies;

          (2)  the Depositary Receipts, when duly executed and delivered by the
     Depositary against the deposit of the New Preferred Stock in accordance
     with the Deposit Agreement, will be validly issued and the registered
     holders thereof will be entitled to the rights specified therein and in the
     Deposit Agreement;

          (3)  the execution, delivery and performance by the Company of its
     obligations under the Engagement Letter, the Dealer Manager Agreement and
     the Deposit Agreement and the consummation by the Company of the
     transactions contemplated therein and compliance by the Company with its
     obligations thereunder will not (A) breach or violate the Company's
     Restated Articles of Incorporation, as amended, or Bylaws, as amended, or
     (B) breach or violate, or constitute a default under, (i) the Company's
     Mortgage and Deed of Trust dated as of June 1, 1939, to Citibank, N.A., as
     trustee, (ii) the Indenture, dated as of July 1, 1988, of the Company to
     Chemical Bank, (iii) the Indenture, dated as of April 1, 1998, of the
     Company to The Chase Manhattan Bank, (iv) the Lease Agreement, dated as of
     December 15, 1986, between the Company and IRE-4 of New York, Inc. and all
     agreements of the Company associated therewith, (v) the Loan Agreement,
     dated as of October 1, 1989, between the Company and the City of Forsyth,
     Rosebud County, Montana, and all agreements of the Company associated
     therewith, (vi) the Indenture, dated as of January 1, 1997, of the Company
     to Wilmington Trust Company, (vii) the Agreement for Lease and the Lease
     Agreement, each dated as of February 26, 1993, between the Company and WP
     Funding, Limited Partnership, and all agreements of the Company associated
     therewith, (viii) the Amended and Restated Declaration of Trust of
     Washington Water Power Capital I, dated as of January 23, 1997, or (ix) the
     Amended and Restated Declaration of Trust of Washington Water Power Capital
     II, dated as of June 3, 1997;

<PAGE>


          (4)  no approval, authorization, consent or other order of, or filing
     with, any governmental agency of the State of New York or of the United
     States of America is required under the respective laws of such
     jurisdictions in order for (i) the Engagement Letter, the Dealer Manager
     Agreement or the Deposit Agreement to constitute valid and binding
     obligations of the Company, (ii) the New Preferred Stock or the New Common
     Stock to be validly issued, fully paid and non-assessable, (iii) the Rights
     appurtenant to the New Common Stock to be validly issued or (iv) the
     Depositary Receipts to be validly issued or otherwise in order for the
     transactions contemplated by the Dealer Manager Agreement and the
     Registration Statement to be consummated by the Company.

          (5)  the Company is not and, after giving effect to the offering and
     sale of the New Preferred Stock, will not be, an "investment company" or an
     entity "controlled" by an "investment company," as such terms are defined
     in the Investment Company Act of 1940, as amended;

          (6)  the Registration Statement and Prospectus (except the financial
     statements and other financial and statistical data contained therein, upon
     which we do not pass) comply as to form in all material respects with the
     applicable requirements of the 1933 Act and the applicable instructions,
     rules and regulations promulgated thereunder; and the Registration
     Statement has become effective under the 1933 Act and, to the best of our
     knowledge, no proceedings for a stop order with respect thereto are pending
     or threatened under Section 8(d) of the 1933 Act;

          (7)  the documents incorporated by reference into the Registration
     Statement and the Prospectus, as amended or supplemented at the date of
     this opinion, and the Schedule 13E-4 (except the financial statements and
     other financial and statistical data contained therein, upon which we do
     not pass), when they were filed with the SEC, complied as to form in all
     material respects with the applicable requirements of the Securities
     Exchange Act of 1934, as amended, and the applicable instructions, rules
     and regulations promulgated thereunder; and

          (8)  the statements made in the Registration Statement under the
     captions "Description of the RECONS", "Description of Capital Stock" and
     "Certain Federal Income Tax Consequences" fairly presents the information
     purported to be given.

          We have acted as counsel to the Company primarily with respect to
general compliance with the federal securities laws and specific financing and
other corporate transactions.  Our engagement regarding such compliance was
limited to advising the Company as to the requirements of such laws and the
rules

<PAGE>



and regulations of the SEC thereunder, assisting the Company in the 
assessment of the materiality of particular matters brought to our attention 
and generally reviewing, with a view toward such compliance, drafts prepared 
by the Company of the documents incorporated by reference into the 
Registration Statement and the Prospectus.  We have not acted as general 
counsel to the Company and have not, except for specific purposes, attended 
meetings of the Board of Directors of the Company, or committees thereof, or 
of officers of the Company; nor have we otherwise been in a position to 
become aware of matters not specifically brought to our attention by officers 
or other employees of, or other counsel to, the Company.

          Accordingly, in the course of the preparation by the Company of the
Registration Statement and the Prospectus, we participated in conferences with
certain officers and other employees of the Company, with other counsel for the
Company, with you and your counsel, and with Deloitte & Touche LLP, the
independent certified public accountants who examined the financial statements
included in the Registration Statement, but we made no independent verification
of the accuracy or completeness of the representations and statements made to us
by the Company or the information included by the Company in the Registration
Statement or the Prospectus, as amended or supplemented at the date of this
opinion, and we take no responsibility therefor, except insofar as such
information relates to us and as set forth in paragraphs (2) and (8) above.  In
passing upon the forms of the Registration Statement and Prospectus in paragraph
(6) and in rendering the opinion expressed in paragraph (7) above, we have,
therefore, assumed the accuracy and completeness of such representations,
statements and information, except as aforesaid.

          The nature and extent of our engagement by the Company and our
participation in the preparation of the Registration Statement and the
Prospectus, as so amended or supplemented, as described above, would not
necessarily be adequate to bring to our attention all matters which could be
deemed material or to enable us to make a valid assessment of the materiality of
such matters as were brought to our attention.

          However, during the course of our examination of the Registration
Statement and the Prospectus, as so amended or supplemented, and our
participation in the above-mentioned conferences, nothing came to our attention
which gives us reason to believe that (A) when the Registration Statement became
effective, the Registration Statement contained an untrue statement of a
material fact or omitted to state a material fact required to be stated therein
or necessary to make the statements therein not misleading, or that, as of the
date of this opinion, the Prospectus, as so amended or supplemented, contains an
untrue statement of a material fact or omits to state a material fact necessary
in order to make the statements therein, in the light of the circumstances under
which they were made,

<PAGE>


not misleading; provided, however, that we do not express any belief as to 
any financial statements or other financial or statistical information, data 
or computations contained in the Registration Statement or the Prospectus, as 
so amended or supplemented; or (B) there exist any material contracts which 
are required to be filed as exhibits to the Registration Statement which have 
not been so filed.

          The opinions enumerated above are limited to the laws of the State of
New York and the federal law of the United States of America (excluding
therefrom principles of conflicts of laws and state securities or blue sky
laws).  To the extent that such opinions relate to or are dependent upon matters
governed by the laws of other States, they are based upon the assumptions set
forth above or otherwise upon the legal conclusions set forth in the aforesaid
opinions of Paine, Hamblen, Coffin, Brooke & Miller LLP.  For purposes of the
opinion expressed in paragraph (3) above, we have assumed that any document
referred to therein which is not stated to be governed by the law of the State
of New York would be enforced as written.

          This opinion is not being delivered for the benefit of, nor may it be
relied upon by, the holders of the New Preferred Stock, the New Common Stock or
the Depositary Receipts or any other party to which it is not specifically
addressed or to which reliance is not expressly permitted hereby.


                              Very truly yours,

Dear  Ladies and Gentlemen:

     This opinion is being delivered to you at the request of the Washington 
Water Power Company, a Washington corporation (the "Company") pursuant to 
Section 9(a) of the Dealer Manager Agreement, dated October __, 1998 (the 
"Dealer Manager Agreement"), between you and the Company relating to the 
proposed issuance by the Company of up to 2,000,000 shares of a new series of 
the Company's Preferred Stock, no par value, to be designated Preferred 
Stock, Convertible Series L (the "New Preferred Stock").  As contemplated in 
the Dealer Manager Agreement, (a) the New Preferred Stock is to be issued and 
delivered to The Bank of New York, as depositary (the "Depositary") under a 
deposit agreement, to be dated as of ___________, 1998 (the "Deposit 
Agreement"), (b) up to 20,000,000 depositary shares, each constituting a 
one-tenth interest in one share of New Preferred Stock (the "Depositary 
Shares"), will be offered to holders of the company's Common Stock, no par 
value (the "Common Stock"), in exchange for outstanding shares of Common 
Stock on a one-for-one basis (the "Exchange Offer"), and depositary receipts 
("Depositary Receipts") will be delivered to tendering shareholders to 
evidence Depositary Shares, and (c) the New Preferred Stock will be 
convertible into Common Stock, the Common Stock to be issued and delivered 
upon such conversion being hereinafter called the "New Common Stock".  
Capitalized terms used herein but not otherwise defined herein shall have the 
meaning ascribed to them in the Dealer Manager Agreement.

     The Company has filed with the Securities and Exchange Commission (the 
"SEC") under the Securities Act of 1933, as amended (the "1933 Act"), a 
registration statement on Form S-4 (Registration No. 333-61599) for the 
registration under the 1933 Act of (a) the New Preferred Stock, (b) the 
Depositary Shares and (c) the New Common Stock and the Rights (as hereinafter 
defined) 

<PAGE>

appurtenant thereto.  Such registration statement, as amended at the time it 
became effective or at the time of effectiveness of any post-effective 
amendments thereto, is hereinafter called the "Registration Statement", and 
the prospectus contained in the Registration Statement is hereinafter called 
the "Prospectus". As used herein the term "Rights" means the preferred share 
purchase rights issued and to be issued under the Rights Agreement, dated as 
of February 16, 1990, between the Company and First Chicago Trust Company of 
New York, as amended.

     We have examined, or are generally familiar with, the following: (a) the 
Restated Articles of Incorporation, as amended, and the Bylaws, as amended, 
of the Company; (b) the Engagement Letter and the Dealer Manager Agreement; 
(c) the Deposit Agreement; (d) a Certificate of Existence/Authorization 
issued by the Secretary of State of the State of Washington, a Certificate of 
Corporate Status issued by the Secretary of State of the State of Idaho, a 
Certificate of Authorization issued by the Secretary of State of the State of 
Montana, a Certificate of Authorization issued by the Secretary of State of 
the State of Oregon, and a Certificate of Status of Foreign Corporation 
issued by the Secretary of State of the State of California, (e) the relevant 
orders of the Washington Utilities and Transportation Commission ("WUTC"), 
the California Public Utilities Commission (the "CPUC"), the Idaho Public 
Utilities Commission (the "IPUC") and the Public Utility Commission of Oregon 
(the "OPUC"); (f) the Registration Statement); and (g) the documents 
incorporated by reference in the Registration Statement, (the "Incorporated 
Documents"). We have also examined such other documents and satisfied 
ourselves as to such other matters as we have deemed necessary in order to 
render this opinion. We have not examined the certificates evidencing the 
shares of the New Preferred Stock, except a specimen thereof.

     As to various questions of fact (but not as to the legal conclusions 
contained therein) material to the opinions set forth below, in rendering 
such opinions we have relied, with your permission, upon certificates of 
public officials, certificates of officers or other employees of the Company, 
representations contained in the Dealer Manager Agreement, and other oral or 
written assurances by officers or other employees of the Company.

     We have represented the Company in connection with the matters described 
herein and we have acted as counsel to the following subsidiaries; Avista Corp.,
Avista Laboratories, Inc., Avista Advantage, Inc., WP International, Inc., 
Washington Irrigation and Development Company, and WP Finance Co.; Avista 
Energy, Inc.; WWP Fiber, Inc.; and WWP Receivables Corp.  In such capacity, 
we represent the Company and such subsidiaries other than Avista Energy, Inc. 
on various matters referred to us by them.  We represent Avista Energy, Inc. 
on certain specific matters referred to us by it (primarily with respect to 
energy 

<PAGE>

purchase and sale transactions), but not on all matters.  We do not act as 
counsel to other direct or indirect subsidiaries and affiliates of the 
Company.

     We have assumed the genuineness of all signatures, the authenticity of 
all documents submitted to us as originals, the conformity to original 
documents of all documents submitted to us as copies, and the due 
authorization, execution and delivery of all documents by all parties thereto 
other than the Company.

     As used in this opinion, the expression "to the best of our knowledge 
after reasonable inquiry with respect thereto" means that, after an 
examination of the documents made available to us by the Company and after 
inquiries of officers or employees of the Company, we find no reason to 
believe that the opinions expressed herein are factually inaccurate; beyond 
that, however, we have not made an independent factual investigation for the 
purpose of rendering this opinion.

     Based upon the foregoing, and subject to the qualifications set forth 
herein, we are of the opinion that:

          (1)(a)  The Company is a corporation duly incorporated, validly
     existing and in good standing under the laws of the State of Washington and
     the Company has been duly qualified as a foreign corporation for the
     transaction of business and is in good standing under the laws of each
     other jurisdiction in which it owns or leases properties, or conducts any
     business, so as to require such qualification, other than where the failure
     to be so qualified or in good standing would not have a material adverse
     effect on the Company and its subsidiaries taken as a whole.  Each of the
     Company's following subsidiaries; Avista Corp.; Avista Laboratories, Inc.;
     Pentzer Corporation; Avista Energy, Inc.; Avista Advantage, Inc.; WP
     International, Inc.; WP Finance Co.; Washington Irrigation and Development
     Company; WWP  Fiber, Inc.; and WWP Receivables Corp. is a corporation duly
     incorporated, validly existing and in good standing under the laws of the
     State of Washington; these subsidiaries, with the exception of Pentzer
     Corporation, will be referred to hereinafter as the "Designated
     Subsidiaries" or as a "Designated Subsidiary."

                    Each Designated Subsidiary has been duly qualified as a
     foreign corporation for the transaction of business and is in good standing
     under the laws of each other jurisdiction in which it owns or leases
     properties, or conducts any business, so as to require such qualification,
     other than where the failure to be so qualified or in good standing would
     not have a material adverse effect upon such subsidiary.

               (b)  The outstanding shares of Common Stock of the Company have
     been duly authorized and validly issued and are fully paid and 

<PAGE>

     non-assessable; provided, however, that in passing upon the valid issuance
     of and full payment for shares of Common Stock issued pursuant to offerings
     specifically made to shareholders, directors or officers and other
     employees of the Company, we have necessarily assumed that the certificates
     therefor have been duly countersigned and registered by a transfer agent
     and registrar and that upon, the issuance thereof, the Company received the
     full consideration therefor authorized by the Board of Directors of the
     Company.

               (c)  The Company has adequate corporate powers and has all
     material required licenses, permits, approvals and authorizations to own,
     lease and operate its properties and to transact its business in such
     states as are described in the Registration Statement and the Incorporated
     Documents and, to the best of our knowledge after reasonable inquiry with
     respect thereto, is in material compliance with all laws and regulations
     relating to the conduct of its business in such states as are described in
     the Registration Statement and the Incorporated Documents.  The Company has
     adequate corporate powers to execute and deliver, and perform its
     obligations under, the Engagement Letter, the Dealer Manager Agreement and
     the Deposit Agreement and to consummate the transactions contemplated
     thereby.  The Company's Designated Subsidiaries have all material required
     licenses, permits, approvals and authorizations to own, lease and operate
     their properties and to transact their business as described in the
     Registration Statement and the Incorporated Documents and, to the best of
     our knowledge after reasonable inquiry with respect thereto, are in
     material compliance with all laws and regulations relating to the conduct
     of its business in such states as are described in the Registration
     Statement and the Incorporated Documents. Except as described in the
     Registration Statement and the Incorporated Documents, the Designated
     Subsidiaries have not received any actual notice of any proceeding relating
     to revocation or modification of any approval or authorization which would
     have a material adverse impact upon the conduct of each such Designated
     Subsidiary.

               (d)  The outstanding shares of the common stock of each of the
     Company's Significant Subsidiaries have been duly authorized and validly
     issued, are fully paid and non-assessable and are owned by the Company,
     directly or indirectly, free of any liens, encumbrances or security
     interests therein.

          (2)  The WUTC, CPUC, IPUC and OPUC have entered appropriate orders
     (the "Commission Orders") authorizing (a) the issuance and delivery by the
     Company of the New Preferred Stock pursuant to the Exchange Offer and
     (b) the issuance and delivery by the Company of the New Common Stock and
     the Rights appurtenant thereto upon the conversion of the New Preferred
     Stock; each of the Commission Orders, to the best of our 

<PAGE>

     knowledge after reasonable inquiry with respect thereto, remains in full 
     force and effect on the date of this opinion; and no further approval, 
     authorization, consent or other order of, or filing with, any 
     governmental agency of the States of Washington, California, Idaho, 
     Montana and Oregon is legally required for the authorization of the 
     execution, delivery or performance by the Company of the Dealer Manager 
     Agreement or the Deposit Agreement or in order for the Dealer Manager 
     Agreement or the Deposit Agreement to constitute valid and binding 
     obligations of the Company, the authorization of the issuance and 
     delivery by the Company of the New Preferred Stock or in order for the 
     New Preferred Stock to be validly issued and delivered fully paid and 
     non-assessable, the authorization of the issuance and delivery of the 
     New Common Stock and the Rights appurtenant thereto upon the conversion 
     of the New Preferred Stock, or in order for the New Common Stock to be 
     validly issued and delivered, or in order for such Rights to be validly 
     issued, or in order for the Depositary Receipts to be validly issued or 
     in order for the transaction contemplated by the Dealer Manager 
     Agreement and the Prospectus to be consummated by the Company.

          (3)  The Dealer Manager Agreement and the Deposit Agreement have been
     duly authorized, executed and delivered by the Company.

          (4)  The issuance and delivery of the New Preferred Stock pursuant to
     the Exchange Offer, and the issuance and delivery of the New Common Stock
     and the Rights appurtenant thereto upon the conversion of the New Preferred
     Stock, have been duly authorized by all necessary corporate action on the
     part of the Company; the shareholders of the Company have no preemptive
     rights to subscribe for any shares of such stock; and the Company's capital
     stock and the Rights conform to the descriptions thereof in the
     Registration Statement.

          (5)  When (a) the Articles of Amendment have been filed with the
     Secretary of State of the State of Washington and (b) certificates
     representing shares of the New Preferred Stock have been (i) countersigned
     and registered by a transfer agent and registrar, (ii) issued pursuant to
     the Exchange Offer as contemplated in the Registration Statement and
     (iii) delivered under the Deposit Agreement, the New Preferred Stock will
     be validly issued, fully paid and non-assessable.

          (6)  The New Preferred Stock is convertible into the Common Stock as
     provided in the Articles of Amendment; 25,000,000 shares of the New Common
     Stock have been reserved for issuance upon conversion, and, upon such
     conversion, the New Common Stock will be validly issued, fully 

<PAGE>

     paid and non-assessable and the Rights appurtenant thereto will be validly
     issued.

          (7)  The execution, delivery and performance by the Company of its
     obligations under the Engagement Letter, the Dealer Manager Agreement and
     the Deposit Agreement, and the issuance and delivery by the Company of the
     New Preferred Stock pursuant to the Exchange Offer, and the issuance and
     delivery by the Company of the New Common Stock and the Rights appurtenant
     thereto upon the conversion of the New Preferred Stock and the consummation
     by the Company of the transactions contemplated therein and in the
     Prospectus and compliance by the Company with its obligations thereunder
     have been authorized by all necessary corporate action and will not 
     (A) breach or violate the Company's Restated Articles of Incorporation, as
     amended, or Bylaws, as amended, or (B) breach or violate, or constitute a
     default under, (i) any applicable law or statute or order of any court or
     governmental agency of such States having jurisdiction over the Company or
     any of its properties which is material to the Company or (ii) any
     contract, indenture, mortgage, agreement or other instrument to which the
     Company or any of the subsidiaries is a party or to which any of its
     properties is subject and which is listed as an exhibit to any of the
     Incorporated Documents, except that we express no opinion as to any such
     contract, indenture, mortgage, agreement or other instrument which is
     addressed in the separate opinion to you of Thelen Reid & Priest LLP.

          (8)  To the best of our knowledge after reasonable inquiry with
     respect thereto, except as described in the Registration Statement, the
     Prospectus or the Incorporated Documents, there are no legal or
     governmental investigations, actions, suits or proceedings, either pending
     or threatened, which arise out of, threaten against or affect the
     operations of the Company or any Designated Subsidiary in the States of
     Washington, California, Idaho, Montana or Oregon to which the Company is a
     party or to which the Company or any Designated Subsidiary or any of its
     properties are subject and which are material to the Company, other than
     ordinary, routine legal or governmental proceedings incidental to the kind
     of business conducted by the Company, which if determined adversely to the
     Company or any Designated Subsidiary could not individually or in the
     aggregate have, or reasonably be expected to have, a material adverse
     effect on the business of the Company and its subsidiaries, taken as a
     whole.  There are no existing or, to the best of our knowledge after
     reasonable inquiry with respect thereto, threatened lawsuits seeking to
     enjoin the Exchange offer.

          (9)  The descriptions of legal or governmental proceedings contained
     in Item 8 (Note 17) of the Annual Report on Form 10-K for the year ended
     December 31, 1997 and Note 5 of the Quarterly Report on Form 10-Q 

<PAGE>

     for the quarterly periods ended March 31, 1998 and June 30, 1998 are fair
     and accurate descriptions thereof in all material respects.

     As noted above, and we represent the Company and the subsidiaries named 
herein on specific matters referred to us.  Our involvement in the 
preparation of the Registration Statement, the Prospectus and the 
Incorporated Documents was limited to generally reviewing drafts thereof 
prepared by the Company or other counsel to the Company and to participating 
in the conferences referred to below.  However, we have not been engaged to 
make the ultimate determination of materiality for purposes of, or to 
determine the wording and degree of disclosure contained in, the Registration 
Statement, the Prospectus or the Incorporated Documents; we have not been 
engaged to advise the Company with respect to compliance with securities 
laws; and we have not otherwise acted as securities law counsel to the 
Company.

     Accordingly, in such capacity during the course of the preparation by 
the Company of the Registration Statement, the Prospectus and the 
Incorporated Documents, we have participated in conferences with certain 
officers and other employees of the Company, with other counsel for the 
Company, with you and your counsel, and with Deloitte & Touche LLP, the 
independent certified public accountants who examined the financial 
statements included in the Registration Statement, the Prospectus and the 
Incorporated Documents, but we have made no independent verification of the 
accuracy or completeness of the representations and statements made to us by 
the Company or the information included by the Company in the Registration 
Statement, the Prospectus or the Incorporated Documents, and we take no 
responsibility therefor, except as specifically set forth herein and insofar 
as such information relates to us.

     The nature and extent of our engagement by the Company and our 
participation in the above-mentioned conferences, as described above, would 
not necessarily be adequate to bring to our attention all matters which could 
be deemed material or to enable us to make a valid assessment of the 
materiality of such matters as were brought to our attention or of the 
wording and degree of disclosure contained in the Registration Statement, the 
Prospectus or the Incorporated Documents.

     However, during the course of our examination of the Registration 
Statement, the Prospectus and the Incorporated Documents and our 
participation in the above-mentioned conferences, nothing came to our 
attention which gives us reason to believe that, when the Registration 
Statement became effective, the Registration Statement, the Prospectus and 
the Incorporated Documents contained an untrue statement of a material fact 
or omitted to state a material fact necessary to make the statements therein 
not misleading, or that, as of the date of this opinion, the Prospectus, as 
then amended or supplemented, and the Incorporated 

<PAGE>

Documents contain an untrue statement of a material fact or omit to state a 
material fact necessary in order to make the statements therein, in the light 
of the circumstances under which they were made, not misleading; provided, 
however, that we do not express any belief as to any financial statements or 
other financial or statistical information, data or computations contained in 
the Registration Statement, the Prospectus or the Incorporated Documents, or 
as to any specific sections contained within the Registration Statement or 
the Prospectus other than the sections entitled "The Company" and 
"Description of Capital Stock" insofar as such descriptions relate to 
Washington law and Part II of the Registration Statement.

     The opinions expressed above are limited to the laws of the States of 
Washington, California, Idaho, Montana and Oregon (excluding therefrom 
principles of conflicts of laws, state securities or blue sky laws, laws of 
political subdivisions of such States and the federal law of the United 
States of America). For purposes of the opinion expressed in paragraph (7) 
above, we have assumed that any document referred to therein which is not 
stated to be governed by the laws of the States of Washington, California, 
Idaho, Montana and Oregon would be enforced as written.

     This opinion is limited to the opinions and confirmations expressed 
above, and no additional opinions or confirmations are to be implied or 
inferred. Without limiting the generality of the foregoing, it is 
specifically understood that we express no opinion or confirmation as to 
whether the Engagement Letter, the Dealer Manager Agreement, the Deposit 
Agreement or related documents constitute legal, valid and binding 
obligations, enforceable in accordance with their terms.

     This opinion is being delivered as of this date solely in connection 
with the Exchange offer for the benefit of the addressee hereof. Davis Polk & 
Wardwell is hereby also authorized to rely upon this opinion in connection 
therewith as if it were addressed to them. This opinion is not being 
delivered, nor may it be relied upon, for any other purpose; this opinion is 
not being delivered for the benefit of, nor may it be relied upon by, the 
holders of the New Preferred Stock, the New Common Stock or the Depositary 
Receipts or any other party to which it is not specifically addressed or to 
which reliance is not expressly permitted hereby; and this opinion is not to 
be used, delivered, circulated, quoted or otherwise referred to except as 
expressly permitted hereby.

     This opinion is given as of the date hereof, without any obligation upon 
us to update this opinion or to advise the addressees hereof or any other 
party of any changes in circumstances or laws that may hereafter be brought 
to our attention or occur which may affect this opinion.

     Capitalized terms used in this Schedule II and not defined herein shall 
have the meanings ascribed thereto in the Dealer Manager Agreement to which 
this Schedule II is appended.

                     OPINION OF COUNSEL TO DEALER MANAGER

       (i)  the Dealer Manager Agreement has been duly authorized, executed 
and delivered by the Company;

      (ii)  the Deposit Agreement has been duly executed and delivered by the 
Company and constitutes a valid and legally binding obligation of the Company 
enforceable against the Company in accordance with its terms, subject to 
bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium and 
similar laws of general applicability relating to or affecting creditors' 
rights and to general equity principles;

     (iii)  upon due issuance by the Depositary of the Receipts evidencing 
the RECONS against the deposit of the Original Securities in respect thereof 
in accordance with the provisions of the Deposit Agreement, such Receipts 
will be duly and validly issued and persons in whose names such Receipts are 
registered will be entitled to the rights specified therein and in the 
Deposit Agreement; and

      (iv)  such counsel believes that the Registration Statement and the 
Exchange Offer Prospectus and any amendments and supplements thereto (other 
than the financial statements and related schedules or other financial or 
statistical information data or computations therein, as to which such 
counsel need express no belief) comply as to form in all material respects 
with the requirements of the Securities Act and believes that (other than the 
financial statements and related schedules or other financial or statistical 
information data or computations therein, as to which such counsel need 
express no belief) the Registration Statement and the Prospectus did not 
contain any untrue statement of a material fact or omit to state a material 
fact required to be stated therein or necessary to make the statements 
therein not misleading, and that the Exchange Offer Prospectus, as amended or 
supplemented, if applicable, does not contain any untrue statement of a 
material fact or omit to state a material fact necessary in order to make the 
statements therein, in the light of the circumstances under which they were 
made, not misleading.

     THIRD:

     (a)  The amount of capital with which the Corporation will begin to carry
          on business hereunder shall be FIVE MILLION FIVE HUNDRED DOLLARS
          ($5,000,500).

     (b)  The aggregate number of shares of capital stock which the Corporation
          shall have authority to issue is 210,000,000 shares, divided into
          10,000,000 shares of Preferred Stock without nominal or par value,
          issuable in series as hereinafter provided, and 200,000,000 shares of
          Common Stock without nominal or par value.

     (c)  A statement of the preferences, limitations and relative rights of
          each class of capital stock of the Corporation, namely, the Preferred
          Stock without nominal or par value and the Common Stock without
          nominal or par value, of the variations in the relative rights and
          preferences as between series of the Preferred Stock insofar as the
          same are fixed by these Articles of Incorporation, and of the
          authority vested in the Board of Directors of the Corporation to
          establish series of Preferred Stock and to fix and determine the
          variations in the relative rights and preferences as between series
          insofar as the same are not fixed by these Articles of Incorporation
          and as to which there may be variations between series is as follows.

     (d)  The shares of the Preferred Stock may be divided into and issued in
          series.  Each series shall be so designated as to distinguish the
          shares thereof from the shares of all other series of the Preferred
          Stock and all other classes of capital stock of the Corporation.  To
          the extent that these Articles of Incorporation shall not have
          established series of the Preferred Stock and fixed and determined the
          variations in the relative rights and preferences as between series,
          the Board of Directors shall have authority, and is hereby expressly
          vested with authority, to divide the Preferred Stock into series and,
          within the limitations set forth in these Articles of Incorporation
          and such limitations as may be provided by law, to fix and determine
          the relative rights and preferences of any series of the Preferred
          Stock so established.  Such action by the Board of Directors shall be
          expressed in a resolution or resolutions adopted by it prior to the
          issuance of shares of each series, which resolution or resolutions
          shall also set forth the distinguishing designation of the particular
          series of the Preferred Stock established thereby.  Without limiting
          the generality of the foregoing, authority is hereby expressly vested
          in the Board of Directors so to fix and determine, with respect to any
          series of the Preferred Stock:
     
          (1)  the rate or rates of dividend, if any, which may be expressed in
               terms of a formula or other method by which such rate or rates
               shall be calculated from time to time, and the date or dates on
               which dividends may be payable;

<PAGE>

          (2)  whether shares may be redeemed and, if so, the redemption price
               and the terms and conditions of redemption;

          (3)  the amount payable upon shares in event of voluntary and
               involuntary liquidation;

          (4)  sinking fund provisions, if any, for the redemption or purchase
               of shares; and

          (5)  the terms and conditions, if any, on which shares may be
               converted.
     
               All shares of the Preferred Stock of the same series shall be
          identical except that shares of the same series issued at different
          times may vary as to the dates from which dividends thereon shall be
          cumulative; and all shares of the Preferred Stock, irrespective of
          series, shall constitute one and the same class of stock, shall be of
          equal rank, and shall be identical except as to the designation
          thereof, the date or dates from which dividends on shares thereof
          shall be cumulative, and the relative rights and preferences set forth
          above in clauses (1) through (5) of this subdivision (d), as to which
          there may be variations between different series.  Except as may be
          otherwise provided by law, by subdivision (j) of this Article THIRD,
          or by the resolutions establishing any series of Preferred Stock in
          accordance with the foregoing provisions of this subdivision (d),
          whenever the written consent, affirmative vote, or other action on the
          part of the holders of the Preferred Stock may be required for any
          purpose, such consent, vote or other action shall be taken by the
          holders of the Preferred Stock as a single class irrespective of
          series and not by different series.
     
     (e)  Out of any funds legally available for the payment of dividends, the
          holders of the Preferred Stock of each series shall be entitled, in
          preference to the holders of the Common Stock, to receive, but only
          when and as declared by the Board of Directors, dividends at the rate
          or rates fixed and determined with respect to each series in
          accordance with these Articles of Incorporation, and no more, payable
          as hereinafter provided. Such dividends shall be cumulative so that if
          for all past dividend periods and the then current dividend periods
          dividends shall not have been paid or declared and set apart for
          payment on all outstanding shares of each series of the Preferred
          Stock, at the dividend rates fixed and determined for the respective
          series, the deficiency shall be fully paid or declared and set apart
          for payment before any dividends on the Common Stock shall be paid or
          declared and set apart for payment; provided, however, that nothing in
          this subdivision (e) or elsewhere in these Articles of Incorporation
          shall prevent the simultaneous declaration and payment of dividends on
          both the Preferred Stock and the Common Stock if there are sufficient
          funds legally available to pay all dividends concurrently. Dividends
          on all shares of the Preferred Stock of each series shall be
          cumulative from the date of issuance of shares of such series.  If
          more than one series of the Preferred Stock shall be outstanding and
          if dividends on each series shall not have been paid or declared and
          set apart for payment, at the dividend rate or rates fixed and
          determined for such series, the shares of the Preferred Stock of each
          series shall share ratably in the payment of dividends including
          accumulations, if any, in accordance with the sums which would be
          payable on such shares if all dividends were declared and paid in
          full.  As to all series of Preferred Stock, the dividend payment dates
          for regular dividends shall be the fifteenth day of March, June,
          September and December in each year, unless other dividend payment
          dates shall have been fixed and determined for any series in
          accordance with subdivision (d) of this Article THIRD, and the
          dividend period in respect of which each regular dividend shall be
          payable in respect of each series shall be the period commencing on
          the next preceding dividend payment date for such series and ending on
          the day next preceding the dividend payment date for such dividend. 
          No interest, or sum of money in lieu of interest, shall be payable in
          respect of any dividend payment or payments which may be in arrears.
     
     (f)  Subject to the limitations set forth in paragraph (e) or elsewhere in
          these Articles of Incorporation (and subject to the rights of any
          class of stock hereafter authorized), dividends may be paid on the
          Common Stock when and as declared by the Board of Directors out of any
          funds legally available for the payment of dividends, and no holder of
          shares of any series of the Preferred Stock as such shall be entitled
          to share therein.

<PAGE>
     
     (g)  In the event of any voluntary dissolution, liquidation or winding up
          of the Corporation, before any distribution or payment shall be made
          to the holders of the Common Stock, the holders of the Preferred Stock
          of each series then outstanding shall be entitled to receive out of
          the net assets of the Corporation available for distribution to its
          shareholders the respective amounts per share fixed and determined in
          accordance with these Articles of Incorporation to be payable on the
          shares of such series in the event of voluntary liquidation, and no
          more, and in the event of any involuntary dissolution, liquidation or
          winding up of the Corporation, before any distribution or payment
          shall be made to the holders of the Common Stock, the holders of the
          Preferred Stock of each series then outstanding shall be entitled to
          receive out of the net assets of the Corporation available for
          distribution to its shareholders the respective amounts per share
          fixed and determined in accordance with these Articles of
          Incorporation to be payable on the shares of such series in the event
          of involuntary liquidation, and no more.  If upon any dissolution,
          liquidation or winding up of the Corporation, whether voluntary or
          involuntary, the net assets of the Corporation available for
          distribution to its shareholders shall be insufficient to pay the
          holders of all outstanding shares of Preferred Stock of all series the
          full amounts to which they shall be respectively entitled as
          aforesaid, the entire net assets of the Corporation available for
          distribution shall be distributed ratably to the holders of all
          outstanding shares of Preferred Stock of all series in proportion to
          the amounts to which they shall be respectively so entitled.  For the
          purposes of this and the next succeeding subdivision, and without
          limiting the right of the Corporation to distribute its assets or to
          dissolve, liquidate or wind up in connection with any sale, merger or
          consolidation, the sale of all or substantially all of the property of
          the Corporation, or the merger or consolidation of the Corporation
          into or with any other corporation or corporations, shall not be
          deemed to be a distribution of assets or a dissolution, liquidation or
          winding up of the Corporation, whether voluntary or involuntary.
     
     (h)  Subject to the limitations set forth in subdivision (g) of this
          Article THIRD or elsewhere in these Articles of Incorporation (and
          subject to the rights of any class of stock hereafter authorized) upon
          any dissolution, liquidation or winding up of the Corporation, whether
          voluntary or involuntary, any net assets of the Corporation available
          for distribution to its shareholders shall be distributed ratably to
          holders of the Common Stock.
     
     (i)  The Preferred Stock may be redeemed in accordance with the following
          provisions of this subdivision (i):
     
          (1)  Each series of the Preferred Stock which has been determined to
               be redeemable as permitted by subdivision (d) of this Article
               THIRD may be redeemed in whole or in part by the Corporation, at
               its election expressed by resolution of the Board of Directors,
               at any time or from time to time, at the then applicable
               redemption price fixed and determined with respect to each
               series, subject however, to any terms and conditions specified in
               respect of any series of the Preferred Stock in accordance with
               subdivision (d) of this Article THIRD.  If less than all of the
               shares of any series are to be redeemed, the redemption shall be
               made either pro rata or by lot in such manner as the Board of
               Directors shall determine.
     
          (2)  In the event the Corporation shall so elect to redeem shares of
               the Preferred Stock, notice of the intention of the Corporation
               to do so and of the date and place fixed for redemption shall be
               mailed not less than thirty nor more than ninety days before the
               date fixed for redemption to each holder of shares of the
               Preferred Stock to be redeemed at his address as it shall appear
               on the books of the Corporation, and on and after the date fixed
               for redemption and specified in such notice (unless the
               Corporation shall default in making payment of the redemption
               price), such holders shall cease to be shareholders of the
               Corporation with respect to such shares and shall have no
               interest in or claim against the Corporation with respect to such
               shares, excepting only the right to receive the redemption price
               therefor from the Corporation on the date fixed for redemption,
               without interest, upon endorsement, if required, and surrender of
               their certificates for such shares.
     
          (3)  Contemporaneously with the mailing of notice of redemption of any
               shares of the Preferred Stock as aforesaid or at any time
               thereafter on or before the date fixed for redemption, the

<PAGE>

               Corporation may, if it so elects, deposit the aggregate
               redemption price of the shares to be redeemed with any bank or
               trust company doing business in the City of New York, New York,
               or Spokane, Washington, having a capital and surplus of at least
               $5,000,000, named in such notice, payable on the date fixed for
               redemption in the proper amounts to the respective holders of the
               shares to be redeemed, upon endorsement, if required, and
               surrender of their certificates for such shares, and on and after
               the making of such deposit such holders shall cease to be
               shareholders of the Corporation with respect to such shares and
               shall have no interest in or claim against the Corporation with
               respect to such shares, excepting only the right to exercise such
               redemption or exchange rights, if any, on or before the date
               fixed for redemption as may have been provided with respect to
               such shares or the right to receive the redemption price of their
               shares from such bank or trust company on the date fixed for
               redemption, without interest, upon endorsement, if required, and
               surrender of their certificates for such shares.

          (4)  If the Corporation shall have so elected to deposit the
               redemption moneys with a bank or trust company, any moneys so
               deposited which shall remain unclaimed at the end of six years
               after the redemption date shall be repaid to the Corporation, and
               upon such repayment holders of Preferred Stock who shall not have
               made claim against such moneys prior to such repayment shall be
               deemed to be unsecured creditors of the Corporation for an 
               amount, without interest, equal to the amount they would
               theretofore have been entitled to receive from such bank or trust
               company.  Any redemption moneys so deposited which shall not be
               required for such redemption because of the exercise, after the
               date of such deposit, of any right of conversion or exchange or
               otherwise, shall be returned to the Corporation forthwith.  The
               Corporation shall be entitled to receive any interest allowed by
               any bank or trust company on any moneys deposited with such bank
               or trust company as herein provided, and the holders of any
               shares called for redemption shall have no claim against any such
               interest.

          (5)  Nothing herein contained shall limit any legal right of the
               Corporation to purchase or otherwise acquire any shares of the
               Preferred Stock.
     
     (j)  The holders of the Preferred Stock shall not have any right to vote
          for the election of Directors or for any other purpose except as
          otherwise provided by law and as set forth below in this subdivision
          of this Article THIRD or elsewhere in these Articles of Incorporation.
          Holders of Preferred Stock shall be entitled to notice of each meeting
          of shareholders at which they shall have any right to vote but except
          as may be otherwise provided by law shall not be entitled to notice of
          any other meeting of shareholders.
     
          (1)  Whenever and as often as, at any date, dividends payable on any
               shares of the Preferred Stock shall be in arrears in an amount
               equal to the aggregate amount of dividends accumulated on such
               shares of the Preferred Stock over the eighteen-month period
               ended on such date, the holders of the Preferred Stock of all
               series, voting separately and as a single class, shall be
               entitled to vote for and to elect a majority of the Board of
               Directors, and the holders of the Common Stock, voting separately
               and as a single class, shall be entitled to vote for and to elect
               the remaining Directors of the Corporation.  The right of the
               holders of the Preferred Stock to elect a majority of the Board
               of Directors shall, however, cease when all defaults in the
               payment of dividends on their stock shall have been cured and
               such dividends shall be declared and paid out of any funds
               legally available therefor as soon as in the judgment of the
               Board of Directors is reasonably practicable.  The terms of
               office of all persons who may be Directors of the Corporation at
               the time the right to elect Directors shall accrue to the holders
               of the Preferred Stock as herein provided shall terminate upon
               the election of their successors at a meeting of the shareholders
               of the Corporation then entitled to vote.  Such election shall be
               held at the next Annual Meeting of Shareholders or may be held at
               a special meeting of shareholders but shall be held upon notice
               as provided in the Bylaws of the Corporation for a special
               meeting of the shareholders.  Any vacancy in the Board of
               Directors occurring during any period when the Preferred Stock
               shall have elected representatives on the Board shall be filled
               by a majority vote of the remaining Directors representing the
               class of stock theretofore represented by 

<PAGE>

               the Director causing the vacancy.  At all meetings of the 
               shareholders held for the purpose of electing Directors during 
               such times as the holders of the Preferred Stock shall have 
               the exclusive right to elect a majority of the Board of 
               Directors of the Corporation, the presence in person or by 
               proxy of the holders of a majority of the outstanding shares 
               of Preferred Stock of all series shall be required to 
               substitute a quorum of such class for the election of 
               Directors, and the presence in person or by proxy of the 
               holders of a majority of the outstanding shares of Common 
               Stock shall be required to constitute a quorum of such class 
               for the election of Directors; provided, however, that the 
               absence of a quorum of the holders of stock of either class 
               shall not prevent the election at any such meeting, or 
               adjournment thereof, of Directors by the other class if the 
               necessary quorum of the holders of stock of such class is 
               present in person or by proxy at such meeting; and provided 
               further, that, in the absence of a quorum of the holders of 
               stock of either class, a majority of those holders of such 
               stock who are present in person or by proxy shall have the 
               power to adjourn the election of those Directors to be elected 
               by that class from time to time without notice, other than 
               announcement at the meeting, until the requisite amount of 
               holders of stock of such class shall be present in person or 
               by proxy.

          (2)  So long as any shares of the Preferred Stock shall be
               outstanding, the Corporation shall not, without the affirmative
               vote of the holders of at least a majority of the shares of the
               Preferred Stock at the time outstanding, adopt any amendment to
               these Articles of Incorporation if such amendment would:
     
               (i)    create or authorize any new class of stock ranking prior
                      to or on a parity with the Preferred Stock as to
                      dividends or upon dissolution, liquidation or winding up;

               (ii)   increase the authorized number of shares of the Preferred
                      Stock; or

               (iii)  change any of the rights or preferences of the Preferred
                      Stock at the time outstanding provided, however, that if
                      any proposed change of any of the rights or preferences
                      of any outstanding shares of the Preferred Stock would
                      affect the holders of shares of one or more, but not all,
                      series of the Preferred Stock then outstanding, only the
                      affirmative vote of the holders of at least a majority of
                      the total number of outstanding shares of all series so
                      affected shall be required; and provided further, that
                      nothing herein shall authorize the adoption of any
                      amendment to these Articles of Incorporation by the vote
                      of the holders of a lesser number of shares of the
                      Preferred Stock, or of any other class of stock, or of
                      all classes of stock, than is required for such an
                      amendment by the laws of the state of Washington at the
                      time applicable thereto.
     
          (3)  So long as any shares of the Preferred Stock shall be
               outstanding, the Corporation shall not, without the affirmative
               vote of the holders of at least a majority of the shares of the
               Preferred Stock at the time outstanding, issue any shares of the
               Preferred Stock, or of any other class of stock ranking prior to
               or on a parity with the Preferred Stock as to dividends or upon
               dissolution, liquidation or winding up, unless the net income of
               the Corporation available for the payment of dividends for a
               period of twelve consecutive calendar months within the fifteen
               calendar months immediately preceding the issuance of such shares
               (including, in any case in which such shares are to be issued in
               connection with the acquisition of new property, the net income
               of the property so to be acquired, computed on the same basis as
               the net income of the Corporation) is at least equal to one and
               one-half times the annual dividend requirements on all shares of
               the Preferred Stock, and on all shares of all other classes of
               stock ranking prior to or on a parity with the Preferred Stock as
               to dividends or upon dissolution, liquidation or winding up,
               which will be outstanding immediately after the issuance of such
               shares, including the shares proposed to be issued; provided,
               however, that if the shares of any series of the Preferred Stock
               or any such prior or parity stock shall have a variable dividend
               rate, the annual dividend requirement on the shares of such
               series shall be determined by reference to the weighted average
               dividend rate on such shares during the twelve-month period for
               which the net income of the Corporation available for the payment
               of dividends shall have been determined; and 

<PAGE>

               provided, further, that if the shares of the series to be 
               issued are to have a variable dividend rate, the annual 
               dividend requirement on the shares of such series shall be 
               determined by reference to the initial dividend rate upon the 
               issuance of such shares.  In any case where it would be 
               appropriate, under generally accepted accounting principles to 
               combine or consolidate the financial statements of any parent 
               or subsidiary of the Corporation with those of the 
               Corporation, the foregoing computation may be made on the 
               basis of such combined or consolidated financial statements.
     
     (k)  Subject to the limitations set forth in subdivision (j) of this
          Article THIRD (and subject to the rights of any class of stock
          hereafter authorized), and except as may be otherwise provided by law,
          the holders of the Common Stock shall have the exclusive right to vote
          for the election of Directors and for all other purposes.  At each
          meeting of shareholders, each holder of stock entitled to vote thereat
          shall be entitled to one vote for each share of such stock held by him
          and recorded in his name on the record date for such meeting, and may
          vote and otherwise act in person or by proxy; provided, however, that
          at each election for Directors every shareholder entitled to vote at
          such election shall have the right to vote the number of shares held
          by him for as many persons as there are Directors to be elected and
          for whose election he has the right to vote, or to cumulate his votes
          by giving one candidate as many votes as the number of such Directors
          multiplied by the number of his shares shall equal, or by distributing
          such votes on the same principle among any number of such candidates.
     
     (l)  Subject to the limitations set forth in subdivision (j) of this
          Article THIRD (and subject to the rights of any class of stock
          hereafter authorized), and except as may be otherwise provided by law,
          upon the vote of a majority of all of the Directors of the Corporation
          and of the holders of record of two-thirds of the total number of
          shares of the Corporation then issued and outstanding and entitled to
          vote (or, if the vote of a larger number or different proportion of
          shares is required by the laws of the state of Washington,
          notwithstanding the above agreement of the shareholders of the
          Corporation to the contrary, then upon the vote of the holders of
          record of the larger number or different proportion of shares so
          required) the Corporation may from time to time create or authorize
          one or more other classes of stock with such preferences,
          designations, rights, privileges, powers, restrictions, limitations
          and qualifications as may be determined by said vote, which may be the
          same or different from the preferences, designations, rights,
          privileges, powers, restrictions, limitations and qualifications of
          the classes of stock of the Corporation then authorized and/or the
          Corporation may increase or decrease the number of shares of one or
          more of the classes of stock then authorized.
     
     (m)  All stock of the Corporation without nominal or par value whether
          authorized herein or upon subsequent increases of capital stock or
          pursuant to any amendment hereof may be issued, sold and disposed of
          by the Corporation from time to time for such consideration in labor,
          services, money or property as may be fixed from time to time by the
          Board of Directors and authority to the Board of Directors so to fix
          such consideration is hereby granted by the shareholders.  The
          consideration received by the Corporation from the issuance and sale
          of new or additional shares of capital stock without par value shall
          be entered in the capital stock account.

     (n)  No holder of any stock of the Corporation shall be entitled as of
          right to purchase or subscribe for any part of any stock of the
          Corporation authorized herein or of any additional stock of any class
          to be issued by reason of any increase of the authorized capital stock
          of the Corporation or of any bonds, certificates of indebtedness,
          debentures or other securities convertible into stock of the
          Corporation but any stock authorized herein or any such additional
          authorized issue of any stock or of securities convertible into stock
          may be issued and disposed of by the Board of Directors to such
          persons, firms, corporations or associations upon such terms and
          conditions as the Board of Directors in their discretion may determine
          without offering any thereof on the same terms or any terms to the
          shareholders then of record or to any class of shareholders.
     
     (o)  (1)  SERIES I.  There is hereby established a ninth series of the
               Preferred Stock of the Corporation which shall have, in addition
               to the general terms and characteristics of all of the authorized
               shares of Preferred Stock of the Corporation, the following

                              satisfied in full the cumulative sinking fund
                              requirement to redeem shares of said ninth series
                              pursuant to this subparagraph (d), and if at such
                              time the Corporation shall be required pursuant to
                              a sinking or similar fund to redeem or purchase
                              shares of any other series of the Preferred Stock
                              or any other class of stock ranking as to
                              dividends and distributions of assets on a parity
                              with the Preferred Stock, any funds of the
                              Corporation legally available for the purpose
                              shall be allocated among all such sinking or
                              similar funds for series of the Preferred Stock
                              and such parity stock in proportion to the
                              respective amounts then required for the
                              satisfaction thereof.

               (e)    The shares of said ninth series shall not, by their
                      terms, be convertible.

                              of $100.00 per share plus an amount equivalent to

                              Corporation shall be entitled, at its option, on

                              however, that the option of the Corporation to so

                              not reduce the sinking fund requirements of this

                              Corporation shall be entitled, at its option, to

                              any other sinking fund redemption requirement.  In
                              the case of any redemption pursuant to this
                              subparagraph (d), the shares to be redeemed shall
                              be selected by lot among the holders of the shares
                              of said eleventh series then outstanding in such
                              manner as the appropriate Officers of the
                              Corporation shall determine to result in a random
                              selection.  The shares of said eleventh series

                              subparagraph (d).

                              this subparagraph (d) shall be subject to any
                              applicable restrictions of law and such redemption
                              shall be made only out of funds legally available
                              therefor.

                      (iii)   The sinking fund requirement of the Corporation to
                              redeem shares of said eleventh series pursuant to
                              this subparagraph (d) shall be cumulative.  If at
                              any time the Corporation shall not have satisfied
                              in full the cumulative sinking fund requirement to
                              redeem shares of said eleventh series, the
                              Corporation shall not pay or declare and set apart
                              for payment any dividends upon, or make any other
                              distribution with respect to, or redeem, purchase
                              or otherwise acquire any shares of, the Common
                              Stock or any other class of stock ranking as to
                              dividends and distributions of assets junior to
                              the Preferred Stock.
     
                      (iv)    If at any time the Corporation shall not have
                              satisfied in full the cumulative sinking fund
                              requirement to redeem shares of said eleventh
                              series pursuant to 

<PAGE>

                              this subparagraph (d), and if at such time the 
                              Corporation shall be required pursuant to a 
                              sinking or similar fund to redeem or purchase 
                              shares of any other series of the Preferred 
                              Stock or any other class of stock ranking as to 
                              dividends and distributions of assets on a 
                              parity with the Preferred Stock, any funds of 
                              the Corporation legally available for the 
                              purpose shall be allocated among all such 
                              sinking or similar funds for series of the 
                              Preferred Stock and such parity stock in 
                              proportion to the respective amounts then 
                              required for the satisfaction thereof.
     
          (e)  The shares of said eleventh series shall not, by their terms, be
               convertible.
     
     FOURTH:  The duration of the Corporation shall be perpetual.

     FIFTH:  The number of Directors of the Corporation shall be such number, 
not to exceed eleven (11), as shall be specified from time to time by the 
Board of Directors in the Bylaws; provided, however, that if the right to 
elect a majority of the Board of Directors shall have accrued to the holders 
of the Preferred Stock as provided in paragraph (1) of subdivision (j) of 
Article THIRD, then, during such period as such holders shall have such 
right, the number of directors may exceed eleven (11).  The Directors shall 
be divided into three classes, as nearly equal in number as possible.  
Commencing with the directors elected at the 1987 Annual Meeting of 
Shareholders, the term of office of the first class shall expire at the 1988 
Annual Meeting of Shareholders, the term of office of the second class shall 
expire at the 1989 Annual Meeting of Shareholders and the term of office of 
the third class shall expire at the 1990 Annual Meeting of Shareholders.  At 
each Annual Meeting of Shareholders thereafter, Directors elected to succeed 
those Directors whose terms expire shall be elected for a term of office to 
expire at the third succeeding Annual Meeting of Shareholders after their 
election.  Notwithstanding the foregoing, Directors elected by the holders of 
the Preferred Stock in accordance with paragraph (1) of subdivision (j) of 
Article THIRD shall be elected for a term which shall expire not later than 
the next Annual Meeting of Shareholders.  All Directors shall hold office 
until the expiration of their respective terms of office and until their 
successors shall have been elected and qualified.

     Subject to the provisions of paragraph (1) of subdivision (j) of Article
THIRD, (a) any vacancy occurring in the Board of Directors may be filled by the
affirmative vote of a majority of the remaining Directors though less than a
quorum of the Board of Directors and any director so elected to fill a vacancy
shall be elected for the unexpired term of his or her predecessor in office and
(b) any directorship to be filled by reason of an increase in the number of
Directors may be filled by the Board of Directors for a term of office
continuing only until the next election of Directors by the shareholders.

     No decrease in the number of directors constituting the Board of Directors
shall shorten the term of any incumbent director.

     Subject to the provisions of paragraph (1) of subdivision (j) of Article
THIRD and the provisions of the next preceding paragraph of this Article FIFTH,
any Director may be removed from office at any time, but only for cause and only
by the affirmative vote of the holders of at least a majority of the voting
power of all of the shares of capital stock of the Corporation entitled
generally to vote in the election of directors (such stock being hereinafter in
these Articles of Incorporation called "Voting Stock"), voting together as a
single class, at a meeting of shareholders called expressly for that purpose;
provided, however, that if less than the entire Board of Directors is to be
removed, no one of the directors may be removed if the votes cast against the
removal of such director would be sufficient to elect such director if then
cumulatively voted at an election of the class of Directors of which such
director is a part.

     Notwithstanding anything contained in these Articles of Incorporation to
the contrary, the provisions of this Article FIFTH shall not be altered, amended
or repealed, and no provision inconsistent therewith shall be included in these
Articles of Incorporation or the Bylaws of the Corporation, without the
affirmative vote of the holders of at least eighty percent (80%) of the voting
power of all of the shares of the Voting Stock, voting together as a single
class.

     SIXTH:  That the principal place of business of said Corporation shall be
Spokane, Spokane County, Washington.

<PAGE>

     SEVENTH:  The corporate powers shall be exercised by the Board of
Directors, except as otherwise provided by statute or by these Articles of
Incorporation.  The Board of Directors shall have power to authorize the payment
of compensation to the Directors for services to the Corporation, including fees
for attendance at meetings of the Board of Directors and other meetings, and to
determine the amount of such compensation and fees.

     The Board of Directors shall have power to adopt, alter, amend and repeal
the Bylaws of the Corporation.  To the extent provided under the laws of the
state of Washington, any Bylaws adopted by the Directors under the powers
conferred hereby may be repealed or changed by the shareholders.

     An Executive Committee may be appointed by and from the Board of Directors
in such manner and subject to such regulations as may be provided in the Bylaws,
which committee shall have and may exercise, when the Board is not in session,
all the powers of said Board which may be lawfully delegated subject to such
limitations as may be provided in the Bylaws or by resolutions of the Board. 
The fact that the Executive Committee has acted shall be conclusive evidence
that the Board was not in session at the time of such action.  Additional
committees may be appointed by and from the Board of Directors in such manner
and subject to such regulations as may be provided in the Bylaws.  Any action
required or permitted by these Articles of Incorporation to be taken by the
Board of Directors of the Corporation may be taken by a duly authorized
committee of the Board of Directors, except as otherwise required by law.

     No Director shall have any personal liability to the Corporation or its
shareholders for monetary damages for his or her conduct as a Director of the
Corporation; provided, however, that nothing herein shall eliminate or limit any
liability which may not be so eliminated or limited under Washington law, as
from time to time in effect.  No amendment, modification or repeal of this
paragraph shall eliminate or limit the protection afforded by this paragraph
with respect to any act or omission occurring prior to the effective date
thereof.  

     The Corporation shall, to the full extent permitted by applicable law, as
from time to time in effect, indemnify any person made a party to, or otherwise
involved in, any proceeding by reason of the fact that he or she is or was a
Director of the Corporation against judgments, penalties, fines, settlements and
reasonable expenses actually incurred by him or her in connection with such
proceeding.  The Corporation shall pay any reasonable expenses incurred by a
Director in connection with any such proceeding in advance of the final
determination thereof upon receipt from such Director of such undertakings for
repayment as may be required by applicable law and a written affirmation by such
director that he or she has met the standard of conduct necessary for
indemnification, but without any prior determination, which would otherwise be
required by Washington law, that such standard of conduct has been met.  The
Corporation may enter into agreements with each Director obligating the
Corporation to make such indemnification and advances of expenses as are
contemplated herein.  Notwithstanding the foregoing, the Corporation shall not
make any indemnification or advance which is prohibited by applicable law.  The
rights to indemnity and advancement of expenses granted herein shall continue as
to any person who has ceased to be a Director and shall inure to the benefit of
the heirs, executors and administrators of such a person.

     A Director of the Corporation shall not be disqualified by his office from
dealing or contracting with this Corporation either as a vendor, purchaser or
otherwise, nor shall any transaction or contract of the Corporation be void or
voidable by reason of the fact that any Director, or any firm of which any
Director is a member, or any corporation of which any Director is a shareholder
or Director, is in any way interested in such transaction or contract, provided
that such transaction or contract is or shall be authorized, ratified, or
approved, either (1) by vote of a majority of a quorum of the Board of Directors
or of the Executive Committee without counting in such majority or quorum any
Directors so interested, or a member of a firm so interested, or a shareholder
or Director of a corporation so interested; or (2) by the written consent or by
vote at a shareholders' meeting of the holders of record of a majority in number
of all the outstanding shares of capital stock of the Corporation entitled to
vote; nor shall any Director be liable to account to the Corporation for any
profits realized by and from or through any such transaction or contract of the
Corporation authorized, ratified, or approved as aforesaid by reason of the fact
that he, or any firm of which he is a member, or any corporation of which he is
a shareholder or a Director, was interested in such transaction or contract. 
Nothing herein contained shall create any liability in the events 

<PAGE>

above described or prevent the authorization, ratification or approval of 
such transaction or contract in any other manner approved by law.

     Shareholders shall have no rights, except as conferred by statute or by the
Bylaws, to inspect any book, paper or account of the Corporation.

     Any property of the Corporation not essential to the conduct of its
corporate business may be sold, leased, exchanged, or otherwise disposed of, by
authority of its Board of Directors and the Corporation may sell, lease,
exchange or otherwise dispose of, all of its property and franchises, or any of
its property, franchises, corporate rights, or privileges, essential to the
conduct of its corporate business and purposes upon the consent of and for such
consideration and upon such terms as may be authorized by a majority of all of
the Directors and the holders of two-thirds of the issued and outstanding shares
of the Corporation having voting power (or, if the consent or vote of a larger
number or different proportion of the Directors and/or shares is required by the
laws of the state of Washington, notwithstanding the above agreement of the
shareholders of the Corporation to the contrary, then upon the consent or vote
of the larger number or different proportion of the Directors and/or shares so
required) expressed in writing, or by vote at a meeting of holders of the shares
of the Corporation having voting power duly held as provided by law, or in the
manner provided by the Bylaws of the Corporation, if not inconsistent therewith.
     
     Upon the affirmative vote of the holders of two-thirds of the issued and
outstanding shares of the Corporation having voting power given at a meeting of
the holders of the shares of the Corporation having voting power duly called for
that purpose or when authorized by the written consent of the holders of
two-thirds of the issued and outstanding shares of the Corporation having voting
power and upon the vote of a majority of the Board of Directors, all of the
property, franchises, rights and assets of the Corporation may be sold,
conveyed, assigned and transferred as an entirety to a new company to be
organized under the laws of the United States, the state of Washington or any
other state of the United States, for the purpose of so taking over all the
property, franchises, rights and assets of the Corporation, with the same or a
different authorized number of shares of stock and with the same preferences,
voting powers, restrictions and qualifications thereof as may then attach to the
classes of stock of the Corporation then outstanding so far as the same shall be
consistent with such laws of the United States or of Washington or of such other
state (provided that the whole or any part of such stock or of any class thereof
may be stock with or without a nominal or par value), the consideration for such
sale and conveyance to be the assumption by such new company of all of the then
outstanding liabilities of the Corporation and the issuance and delivery by the
new company of shares of stock (any or all thereof either with or without
nominal or par value) of such new company of the several classes into which the
stock of the Corporation is then divided equal in number to the number of shares
of stock of the Corporation of said several classes then outstanding.  In the
event of such sale, each holder of stock of the Corporation agrees so far as he
may be permitted by the laws of Washington forthwith to surrender for
cancellation his certificate or certificates for stock of the Corporation and to
receive and accept in exchange therefor, as his full and final distributive
share of the proceeds of such sale and conveyance and of the assets of the
Corporation, a number of shares of the stock of the new company of the class
corresponding to the class of the shares surrendered equal in number to the
shares of stock of the Corporation so surrendered, and in such event no holder
of any of the stock of the Corporation shall have any rights or interests in or
against the Corporation, except the right upon surrender of his certificate as
aforesaid properly endorsed, to receive from the Corporation certificates for
such shares of said new company as herein provided.  Such new company may have
all or any of the powers of the Corporation and the certificate of incorporation
and bylaws of such new company may contain all or any of the provisions
contained in the Articles of Incorporation and Bylaws of the Corporation.
     
     Upon the written assent, in person or by proxy, or pursuant to the
affirmative vote, in person or by proxy, of the holders of a majority in number
of the shares then outstanding and entitled to vote (or, if the assent or vote
of a larger number or different proportion of shares is required by the laws of
the state of Washington notwithstanding the above agreement of the shareholders
of the Corporation to the contrary, then upon the assent or vote of the larger
number or different proportion of the shares so required) (1) any or every
statute of the state of Washington hereafter enacted, whereby the rights, powers
or privileges of the Corporation are or may be increased, diminished, or in any
way affected, or whereby the rights, powers or privileges of the shareholders of
corporations organized under the law under which the 

<PAGE>

Corporation is organized are increased, diminished or in any way affected or 
whereby effect is given to the action taken by any part less than all of the 
shareholders of any such corporation shall, notwithstanding any provision 
which may at the time be contained in these Articles of Incorporation or any 
law, apply to the Corporation, and shall be binding not only upon the 
Corporation but upon every shareholder thereof, to the same extent as if such 
statute had been in force at the date of the making and filing of these 
Articles of Incorporation and/or (2) amendments to said Articles authorized 
at the time of the making of such amendments by the laws of the state of 
Washington may be made; provided, however, that (a) the provisions of Article 
THIRD hereof limiting the preemptive rights of shareholders, requiring 
cumulative voting in the election of Directors and regarding entry in the 
capital stock account of consideration received upon the sale of shares of 
capital stock without nominal or par value and all of the provisions of 
Article FIFTH hereof shall not be altered, amended, repealed, waived or 
changed in any way, unless the holders of record of at least two-thirds of 
the number of shares entitled to vote then outstanding shall consent thereto 
in writing or affirmatively vote therefor in person or by proxy at a meeting 
of shareholders at which such change is duly considered.

     Special meetings of the shareholders may be called by the President, the
Chairman of the Board of Directors, a majority of the Board of Directors, any
Executive Committee of the Board of Directors, and shall be called by the
President at the request of the holders of at least two-thirds (2/3) of the
voting power of all of the shares of the Voting Stock, voting together as a
single class.  Only those matters that are specified in the call of or request
for a special meeting may be considered or voted upon at such meeting.

     Notwithstanding anything contained in these Articles of Incorporation to
the contrary, the paragraph in this Article SEVENTH relating to the adoption,
alteration, amendment, change and repeal of the Bylaws of the Corporation, the
paragraph in this Article SEVENTH relating to the calling and conduct of special
meetings of the shareholders and this paragraph, and the provisions of the
Bylaws of the Corporation relating to procedures for the nomination of
Directors, shall not be altered, amended or repealed, and no provision
inconsistent therewith shall be included in these Articles of Incorporation or
the Bylaws of the Corporation, without the affirmative vote of the holders of at
least eighty percent (80%) of the voting power of all the shares of the Voting
Stock, voting together as a single class.

     EIGHTH:

          of Incorporation, and except as otherwise expressly provided in
          subdivision (b) of this Article EIGHTH:
     
     (1)  any merger or consolidation of the Corporation or any Subsidiary (as
          hereinafter defined) with (a) any Interested Shareholder (as
          hereinafter defined) or (b) any other corporation (whether or not
          itself an Interested Shareholder) which is, or after such merger or
          consolidation would be, an Affiliate (as hereinafter defined) of an
          Interested Shareholder; or

     (2)  any sale, lease, exchange, mortgage, pledge, transfer or other
          disposition (in one transaction or a series of transactions) to or
          with any Interested Shareholder or any Affiliate of any Interested
          Shareholder of any assets of the Corporation or any Subsidiary having
          an aggregate Fair Market Value of $10,000,000 or more; or

     (3)  the issuance or transfer by the Corporation or any Subsidiary (in one
          transaction or a series of transactions) of any securities of the
          Corporation or any Subsidiary to any Interested Shareholder or any
          Affiliate of any Interested Shareholder in exchange for cash,
          securities or other property (or a combination thereof) having an
          aggregate Fair Market Value of $10,000,000 or more; or

     (4)  the adoption of any plan or proposal for the liquidation or

<PAGE>

     
     (5)  any reclassification of securities (including any reverse stock
          split), or recapitalization of the Corporation, or any merger or
          consolidation of the Corporation with any of its Subsidiaries or any
          other transaction (whether or not with or into or otherwise involving
          an Interested Shareholder) which has the effect, directly or
          indirectly, of increasing the proportionate share of the outstanding
          shares of any class of equity or convertible securities of the
          Corporation or any Subsidiary which is directly or indirectly owned by
          any Interested Shareholder or any Affiliate of any Interested
          Shareholder;

          shall require the affirmative vote of the holders of at least 80% of
          the voting power of all of the shares of the Voting Stock, voting
          together as a single class.  Such affirmative vote shall be required
          notwithstanding the fact that no vote may be required or that the vote
          of a lower percentage may be specified, by law or in any agreement
          with any national securities exchange or otherwise.  The term
          "Business Combination" as used in this Article EIGHTH shall mean any
          transaction which is referred to in any one or more of paragraphs (1)
          through (5) of this subdivision (a).
     
     (b)  The provisions of subdivision (a) of this Article EIGHTH shall not be
          applicable to any particular Business Combination, and such Business
          Combination shall require only such affirmative vote, if any, as is
          required by law and any other provision of these Articles of
          Incorporation, if all of the conditions specified in either paragraph
          (1) or paragraph (2) below are met:
     
          (1)  The Business Combination shall have been approved by a majority
               of the Continuing Directors (as hereinafter defined); or

          (2)  All of the following conditions shall have been met:
     
               (A)    The aggregate amount of the cash and the Fair Market
                      Value (as hereinafter defined) as of the date of the
                      consummation of the Business Combination of consideration
                      other than cash to be received per share by holders of

                              Interested Shareholder for any shares of Common
                              Stock acquired by it (x) within the two-year
                              period immediately prior to the date of the first

                              Business Combination (the "Announcement Date") or
                              (y) in the transaction in which it became an
                              Interested Shareholder, whichever is higher;

                      (ii)    the Fair Market Value per share of Common Stock on

                      requirements of this subparagraph (B) shall be required 
                      to be met with respect to every class of outstanding 
                      Voting Stock (other than Institutional Voting Stock), 
                      whether or not the Interested Shareholder has 
                      previously acquired any shares of a particular class of 
                      Voting Stock):

                              period upon which the Interested Shareholder
                              acquired any shares of such class of Voting Stock.
     
               (C)    The consideration to be received by holders of a
                      particular class of outstanding Voting Stock (including
                      Common Stock) shall be in cash or in the same form as the
                      Interested Shareholder has previously paid for shares of
                      such class of Voting Stock.  If the Interested
                      Shareholder has paid for shares of any class of Voting
                      Stock with varying forms of consideration, the form of
                      consideration for such class of Voting Stock shall be
                      either cash or the form used to acquire the largest
                      number of shares of such class of Voting Stock previously
                      acquired by it.

               (D)    After such Interested Shareholder has become an
                      Interested Shareholder and prior to the consummation of
                      such Business Combination:
     
                      (i)     except as approved by a majority of the Continuing
                              Directors, there shall have been no failure to
                              declare and pay at the regular date therefor full
                              dividends (whether or not cumulative) on the
                              outstanding shares of stock of all classes ranking
                              prior as to dividends to the Common Stock;

                      (ii)    there shall have been (x) no reduction in the
                              annual rate of dividends paid on the Common Stock
                              (except as necessary to reflect any subdivision of
                              the Common Stock), except as approved by a
                              majority of the Continuing Directors, and (y) an
                              increase in such annual rate of dividends as
                              necessary to reflect any reclassification
                              (including any reverse stock split),
                              recapitalization, reorganization or any similar
                              transaction which has the effect of reducing the
                              number of outstanding shares of the Common Stock,
                              unless the failure to so increase such annual rate
                              is approved by a majority of the Continuing
                              Directors; and

                      (iii)   such Interested Shareholder shall not have become
                              the beneficial owner of any additional shares of
                              Voting Stock except as part of the transaction
                              which results in such Interested Shareholder
                              becoming an Interested Shareholder.
     
<PAGE>

               (E)    After such Interested Shareholder has become an
                      Interested Shareholder, such Interested Shareholder shall
                      not have received the benefit, directly or indirectly
                      (except proportionately as a shareholder), of any loans,
                      advances, guarantees, pledges or other financial
                      assistance or any tax credits or other tax advantages
                      provided by the Corporation, whether in anticipation of

                      Business Combination and complying with the requirements
                      of the Securities Exchange Act of 1934, as amended, and
                      the rules and regulations thereunder (or any subsequent
                      provisions replacing such Act, rules or regulations)
                      shall be mailed to shareholders of the Corporation at
                      least 30 days prior to the consummation of such Business
                      Combination (whether or not such proxy or information
                      statement is required to be mailed pursuant to such Act
                      or subsequent provisions).
     
     (c)  For the purposes of this Article EIGHTH:

          The terms "Affiliate" and "Associate" have the respective meanings
          ascribed to such terms in Rule 12b-2 of the General Rules and
          Regulations under the Securities Exchange Act of 1934, as in effect on
          January 1, 1987.

          A person shall be deemed to be a "beneficial owner" of any Voting
          Stock:
     
               (i)    which such person or any of its Affiliates or Associates
                      beneficially owns, directly or indirectly, or;

               (ii)   which such person or any of its Affiliates or Associates
                      has (a) the right to acquire (whether such right is
                      exercisable immediately or only after the passage of
                      time), pursuant to any agreement, arrangement or
                      understanding or upon the exercise of conversion rights,
                      exchange rights, warrants or options, or otherwise, or
                      (b) the right to vote pursuant to any agreement,
                      arrangement or understanding; or

               (iii)  which is beneficially owned, directly or indirectly, by
                      any other person with which such person or any of its
                      Affiliates or Associates has any agreement, arrangement
                      or understanding for the purpose of acquiring, holding,
                      voting or disposing of any shares of Voting Stock.
     
          For the purposes of determining whether a person is an Interested
          Shareholder the number of shares of Voting Stock deemed to be
          outstanding shall include all shares of which such person is the
          beneficial owner in accordance with the foregoing definition but shall
          not include any other shares of Voting Stock which may be issuable
          pursuant to any agreement, arrangement or understanding, or upon
          exercise of conversion rights, warrants or options, or otherwise.

          The term "Continuing Director" means any member of the Board of
          Directors of the Corporation who is unaffiliated with the Interested
          Shareholder and was a member of the Board of Directors prior to the
          time that the Interested Shareholder became an Interested Shareholder,
          and any successor of a Continuing Director who is unaffiliated with
          the Interested Shareholder and is recommended to succeed a Continuing
          Director by a majority of Continuing Directors then on the Board of
          Directors.

          The term "Fair Market Value" means (i) in the case of stock, the
          highest closing sale price during the 30-day period immediately
          preceding the date in question of a share of such stock on the
          Composite Tape for New York Stock Exchange-Listed Stocks, or, if such
          stock is not quoted on the Composite Tape, on the New York Stock
          Exchange, or, if such stock is not listed on such Exchange, on the
          principal United States securities exchange registered under the
          Securities Exchange Act of 1934, as amended, on which such stock is
          listed, or, if such stock is not listed on any such exchange, the
          highest closing bid quotation with respect to a share of 

<PAGE>

          such stock during the 30-day period preceding the date in question 
          on the National Association of Securities Dealers, Inc. Automated 
          Quotations System or any system then in use, or if no such 
          quotations are available, the fair market value on the date in 
          question of a share of such stock as determined by the Continuing 
          Directors in good faith; and (ii) in the case of property other 
          than cash or stock, the fair market value of such property on the 
          date in question as determined by a majority of the Continuing 
          Directors in good faith.

          The term "Interested Shareholder" shall mean any person (other than
          the Corporation or any Subsidiary) who or which:
     
               (i)    is the beneficial owner, directly or indirectly, of more
                      than 10% of the voting power of the outstanding Voting
                      Stock; or

               (ii)   is an Affiliate of the Corporation and at any time within
                      the two-year period immediately prior to the date in
                      question was the beneficial owner, directly or
                      indirectly, of 10% or more of the voting power of the
                      then outstanding Voting Stock; or

               (iii)  is an assignee of or has otherwise succeeded to any
                      shares of Voting Stock which were at any time within the
                      two-year period immediately prior to the date in question
                      beneficially owned by any Interested Shareholder, if such
                      assignment or succession shall have occurred in the
                      course of a transaction or series of transactions not
                      involving a public offering within the meaning of the
                      Securities Act of 1933, as amended.
     
          The term "Institutional Voting Stock" shall mean any class of Voting
          Stock which was issued to and continues to be held solely by one or
          more insurance companies, pension funds, commercial banks, savings
          banks or similar financial institutions or institutional investors.

          The term "person" shall mean any individual, firm, corporation or
          other entity.

          The term "Subsidiary" shall mean any corporation of which a majority
          of any class of equity security is owned, directly or indirectly, by
          the corporation; PROVIDED, HOWEVER, that for the purposes of the
          definition of Interested Shareholder set forth above, the term
          "Subsidiary" shall mean only a corporation of which a majority of each
          class of equity security is owned, directly or indirectly, by the
          Corporation.

          The term "Voting Stock" has the meaning ascribed to such term in
          Article FIFTH.
     
          In the event of any Business Combination in which the Corporation
          survives, the phrase "consideration other than cash to be received" as
          used in paragraphs 2(A) and 2(B) of subdivision (b) of this Article
          EIGHTH shall include the shares of Common Stock and/or the shares of
          any other class of outstanding Voting Stock retained by the holders of
          such shares.
     
     (d)  The Directors of the Corporation shall have the power and duty to
          determine for the purposes of this Article EIGHTH, on the basis of
          information known to them after reasonable inquiry, (A) whether a
          person is an Interested Shareholder, (B) the number of shares of
          Voting Stock beneficially owned by any person, (C) whether a person is
          an Affiliate or Associate of another person, (D) whether a class of
          Voting Stock is Institutional Voting Stock, and (E) whether the assets
          which are the subject of any Business Combination have, or the
          consideration to be received for the issuance or transfer of
          securities by the Corporation or any Subsidiary in any Business
          Combination has, an aggregate Fair Market Value of $10,000,000 or
          more.
     
          Nothing contained in this Article EIGHTH shall be construed to relieve
          any Interested Shareholder from any fiduciary obligation imposed by
          law.

          Notwithstanding anything contained in these Articles of Incorporation
          to the contrary, the provisions of this Article EIGHTH shall not be
          altered, amended or repealed, and no provision

<PAGE>

          inconsistent therewith shall be included in these Articles of 
          Incorporation or the Bylaws of the Corporation, without the 
          affirmative vote of the holders of at least eighty percent (80%) of 
          the voting power of all of the shares of the Voting Stock, voting 
          together as a single class.

                               ARTICLES OF AMENDMENT
                                         TO
                         RESTATED ARTICLES OF INCORPORATION
                                         OF
                         THE WASHINGTON WATER POWER COMPANY




          Articles of Amendment to the Restated Articles of Incorporation of The
Washington Water Power Company are herein executed by said corporation pursuant
to Section 23B.06.020 of the Washington business corporation act as follows:

          FIRST:    The name of the corporation is The Washington Water Power
Company (the "Corporation").

          SECOND:   The following amendment to the Restated Articles of 
Incorporation of the Corporation, establishing and designating a series of 
shares and fixing and determining certain of the relative rights and 
preferences thereof, was duly adopted by the Board of Directors of the 
Corporation at a meeting held on August 14, 1998 and by the Board Governance 
Committee of the Board of Directors at a meeting held on October __, 1998.  
No approval or consent of shareholders was required.

          THIRD:    The Restated Articles of Incorporation are hereby amended by
the addition of a paragraph (4) to be inserted at the end of subdivision (o) of
Article THIRD, which shall be and read as follows:

          (4)  SERIES L. There is hereby established a twelfth series of the
     Preferred Stock of the Corporation which shall have, in addition to the
     general terms and characteristics of all of the authorized shares of
     Preferred Stock of the Corporation, the following distinctive terms and
     characteristics:

          (a)  The twelfth series of Preferred Stock of the Corporation shall
     consist of _____ shares and be designated as "$12.40 Preferred Stock,
     Convertible Series L".

          (b)  Said twelfth series shall have a dividend rate of $12.40 per
     share per annum; provided, however, that the amount of the dividend per
     share payable on December 15, 1998 shall be $3.10.

          (c)  The shares of said twelfth series shall not, by their terms, be
     redeemable.

          (d)  The amount payable upon the shares of said twelfth series in the
     event of dissolution, liquidation or winding up of the Corporation shall be
     $______ per share plus an amount equivalent to accumulated and unpaid
     dividends thereon, if any, to the date of such dissolution, liquidation or
     winding up.

          (e)  There shall be no sinking fund for the redemption or purchase of
     shares of said twelfth series.


<PAGE>

          (f)(i)(A) Each share of said twelfth series shall be mandatorily
     converted on November 1, 2001 (the "Mandatory Conversion Date") into (1) a
     number of shares of Common Stock determined by reference to the Common
     Equivalent Rate (as hereinafter defined) then in effect plus (2) the right
     to receive an amount, in cash, equivalent to the accumulated and unpaid
     dividends on such share of said twelfth series, if any, to but excluding
     the Mandatory Conversion Date.

          (B)  Each share of said twelfth series shall be convertible, at the
     option of the Company, at any time on or after December 15, 1998 and prior
     to the Mandatory Conversion Date, into (1) a number of shares of Common
     Stock equal to the Optional Conversion Price then in effect, (2) the right
     to receive an amount, in cash, equivalent to the accumulated and unpaid
     dividends on the share of said twelfth series to be converted to but
     excluding the date fixed for conversion plus (3) the right to receive the
     Optional Conversion Premium; it being understood that the Company may not
     so convert less than all shares of said twelfth series.

          (C)  Each share of said twelfth series shall be mandatorily converted,
     at the time of effectiveness of any Extraordinary Transaction, into, or
     into the right to receive, as the case may be, securities and other
     property (including cash) of the same character and in the same respective
     amounts as the holder of such share would have received if such share had
     been converted pursuant to clause (B) above immediately prior to such time
     of effectiveness.

            (ii)(A) The "Common Equivalent Rate" shall be initially ten shares
     of Common Stock for each share of said twelfth series; provided, however,
     that the Common Equivalent Rate shall be subject to adjustment from time to
     time as provided below.  All adjustments to the Common Equivalent Rate
     shall be calculated to the nearest 1/100th of a share of Common Stock.
     Such rate, as adjusted and in effect at any time, is herein called the
     "Common Equivalent Rate."

          (B)  If the Corporation shall do any of the following (each, an
     "Adjustment Event"):

               (1)  pay a dividend or make a distribution with respect to Common
          Stock in shares of Common Stock,

               (2)  subdivide, reclassify or split its outstanding shares of
          Common Stock into a greater number of shares,

               (3)  combine or reclassify its outstanding shares of Common Stock
          into a smaller number of shares, or

               (4)  issue by reclassification of its shares of Common Stock any
          shares of Common Stock other than in an Extraordinary Transaction (as
          hereinafter defined),

     then the Common Equivalent Rate in effect immediately prior to such
     Adjustment Event shall be adjusted so that on the Mandatory Conversion Date
     each share of said twelfth series shall be converted into the number of
     shares of Common Stock that the holder of such share would have owned or
     been entitled to receive after the happening of the Adjustment Event had
     such share been mandatorily converted immediately prior to the record date,
     if any, for such Adjustment Event or, if there is no record date,
     immediately prior to the effectiveness of such Adjustment Event.  In case
     the Adjustment Event is a dividend or distribution, the adjustment to the
     Common Equivalent Rate shall become effective as of the close of business
     on the record date for determination of shareholders entitled to 

                                    -2-
<PAGE>

     receive such dividend or distribution and any shares of Common Stock 
     issuable in payment of a dividend shall be deemed to have been issued 
     immediately prior to the close of business on the record date for such 
     dividend for purposes of calculating the number of outstanding shares 
     of Common Stock under clauses (C) and (D) below; and, in case the 
     Adjustment Event is a subdivision, split, combination or reclassification,
     the adjustment to the Common Equivalent Rate shall become effective 
     immediately after the effective date of such subdivision, split, 
     combination or reclassification. Such adjustment shall be made 
     successively.

          In the event that Rights are separated from the outstanding shares of
     the Common Stock in accordance with the provisions of the Rights Agreement
     such that holders of shares of said twelfth series would not be entitled to
     receive any Rights in respect of the shares of Common Stock issuable upon
     conversion of the shares of said twelfth series, the Common Equivalent Rate
     shall be adjusted by multiplying the Common Equivalent Rate in effect on
     the Distribution Date (as defined in the Rights Agreement) by a fraction
     (1) the numerator of which shall be the Current Market Price per share of
     the outstanding shares of Common Stock on the Trading Date next preceding
     the Distribution Date and (2) the denominator of which shall be such
     Current Market Price less the fair market value (as determined by the Board
     of Directors of the Company, whose determination shall be conclusive, final
     and binding on the Corporation and all shareholders of the Corporation) as
     of such Distribution Date of the portion of the Rights allocable to one
     share of Common Stock.  Such adjustment shall become effective on the
     opening of business on the business day next following the Distribution
     Date and will remain in effect unless and until (A) the Company (i) amends
     the Rights Agreement to provide that upon conversion of the shares of said
     twelfth series the holders thereof will receive, in addition to the shares
     of Common Stock issuable upon such conversion, the Rights which would have
     attached to such shares of Common Stock if the Rights had not become
     separated from the Common Stock pursuant to the Rights Agreement and (ii)
     converts the Preferred Stock into shares of Common Stock with such Rights
     or (B) the Rights expire, terminate or are redeemed, in which case
     appropriate adjustments, if any, shall be made to the Common Equivalent
     Rate consistent with the provisions of this subparagraph (f)(i).
     Notwithstanding the foregoing, in the event the aforesaid fair market value
     of the portion of the Rights allocable to one share of Common Stock is
     equal to or greater than the Current Market Price per share of Common Stock
     on the Trading Date mentioned above, in lieu of the foregoing adjustment,
     adequate provision shall be made so that each holder of shares of said
     twelfth series shall have the right to receive upon conversion the number
     of shares of Common Stock such holder would have received had such holder
     converted each such share immediately prior to the Distribution Date.

          (C)  If the Corporation shall, after the date of the initial issuance
     of shares of said twelfth series, issue rights or warrants to all holders
     of the Common Stock entitling them for a period not exceeding 45 days from
     the date of such issuance to subscribe for or purchase shares of Common
     Stock at a price per share less than the Current Market Price of the Common
     Stock (as hereinafter defined), on the record date for the determination of
     shareholders entitled to receive such rights or warrants, then in each case
     the Common Equivalent Rate shall be adjusted by multiplying the Common
     Equivalent Rate in effect immediately prior to the date of issuance of such
     rights or warrants by a fraction (1) the numerator of which shall be the
     number of shares of Common Stock outstanding on the date of issuance of
     such rights or warrants, immediately prior to such issuance, plus the
     number of additional shares of Common Stock offered for subscription or
     purchase pursuant to such rights or warrants and (2) the denominator of
     which shall be the number of shares of Common Stock outstanding on the date
     of issuance of such rights or warrants, immediately prior to such issuance,
     plus the number of shares of Common Stock which the aggregate offering
     price of the total number of 

                                    -3-

<PAGE>

     shares of Common Stock so offered for subscription or purchase pursuant to 
     such rights or warrants would purchase at such Current Market Price 
     (determined by multiplying such total number of shares by the exercise 
     price of such rights or warrants and dividing the product so obtained 
     by such Current Market Price).  Such adjustment shall become effective 
     as of the close of business on the record date for the determination of 
     shareholders entitled to exercise such rights or warrants. To the extent 
     that shares of Common Stock are not delivered after the expiration of 
     such rights or warrants, the Common Equivalent Rate shall be readjusted
     to the Common Equivalent Rate which would then be in effect had the
     adjustments made upon the issuance of such rights or warrants been made
     upon the basis of delivery of only the number of shares of Common Stock
     actually delivered.  Such adjustment shall be made successively.

          (D)  If the Corporation shall pay a dividend or make any other
     distribution to all holders of its Common Stock of evidences of its
     indebtedness or other assets (including shares of capital stock of the
     Corporation (other than Common Stock) but excluding any distributions and
     dividends referred to in clause (B) above or any cash dividends), or shall
     issue to all holders of its Common Stock rights or warrants to subscribe
     for or purchase any of its securities (other than those referred to in
     clause (C) above), then, in each such case, the Common Equivalent Rate
     shall be adjusted by multiplying the Common Equivalent Rate in effect on
     the record date for the determination of shareholders entitled to receive
     such dividend or distribution mentioned below by a fraction (1) the
     numerator of which shall be the Current Market Price of the Common Stock on
     such record date and (2) the denominator of which shall be such Current
     Market Price per share of Common Stock less the fair market value (as
     determined by the Board of Directors of the Corporation, whose
     determination shall be conclusive, as final and binding upon the
     Corporation and all shareholders of the Corporation) as of such record date
     of the portion of the assets or evidences of indebtedness so distributed,
     or of such subscription rights or warrants, allocable to one share of
     Common Stock.  Such adjustment shall become effective on the opening of
     business on the business day next following the record date for the
     determination of the shareholders entitled to receive such dividend or
     distribution.  Notwithstanding the foregoing, in the event the portion of
     the assets or other evidences of indebtedness so distributed allocable to
     one share of Common Stock has a value equal to or greater than the Current
     Market Price per share of Common Stock on the record date mentioned above,
     in lieu of the foregoing adjustment, adequate provision shall be made so
     that each holder of shares of said twelfth series shall have the right to
     receive upon conversion assets or other evidences of indebtedness having a
     value in the amount such holder would have received had such holder
     converted each such share immediately prior to the record date for such
     dividend or distribution.

          (E)  If the Corporation shall pay a dividend or make any other
     distribution to all holders of its Common Stock exclusively in cash
     (excluding any quarterly cash dividend on Common Stock in any quarter to
     the extent it does not exceed $.18 per share (as adjusted to reflect
     subdivisions or combinations of Common Stock)) the Common Equivalent Rate
     shall be adjusted by multiplying the Common Equivalent Rate in effect on
     the record date for the determination of the shareholders entitled to
     receive such dividend or distribution by a fraction (1) the numerator of
     which shall be such Current Market Price per share of the Common Stock on
     such record date and (2) the denominator of which shall be such Current
     Market Price less the amount of cash so distributed (and not excluded as
     provided above) allocable to one share of Common Stock.  Such adjustment
     shall become effective immediately prior to the opening of business on the
     business day next following record date.  Notwithstanding the foregoing, in
     the event the portion of the cash so distributed allocable to one share of
     Common Stock is equal to or greater than the Current Market Price per share
     of Common Stock on the record date mentioned above, in lieu of the
     foregoing adjustment, adequate provision shall be 

                                    -4-

<PAGE>

     made so that each holder of shares of said twelfth series shall have the 
     right to receive upon conversion the amount of cash such holder would have
     received had such holder converted each such share immediately prior to 
     the record date for such dividend or distribution.  If an adjustment is 
     required to be made pursuant to this clause (E) as a result of a 
     distribution that is a quarterly dividend, such adjustment shall be 
     based upon the amount by which such distribution exceeds the amount of 
     the quarterly cash dividend permitted to be excluded as provided above; 
     and an adjustment is required to be made pursuant to this clause (E) as 
     a result of a distribution that is not a quarterly dividend, such 
     adjustment shall be based upon the full amount of the distribution.

          (F)  Anything herein to the contrary notwithstanding, the Corporation
     may, at its option, make such upward adjustment in the Common Equivalent
     Rate, in addition to the adjustments specified above, as the Corporation in
     its sole discretion may determine to be advisable, in order that any stock
     dividends, subdivision of shares, distribution of rights to purchase stock
     or securities, or a distribution of securities convertible into or
     exchangeable for stock (or any transaction that could be treated as any of
     the foregoing transactions pursuant to Section 305 of the Internal Revenue
     Code of 1986, as amended) hereinafter made by the Corporation to its
     shareholders shall not be taxable.  Any such adjustment shall be made
     effective as of such date as the Board of Directors of the Corporation
     shall determine.  The determination of the Board of Directors of the
     Corporation as to whether or not such an adjustment to the Common
     Equivalent Rate should be made and, if so, as to what adjustment should be
     made and when, shall be conclusive, final and binding on the Corporation
     and all shareholders of the Corporation.

          (G)  As used herein, the "Current Market Price" of a share of Common
     Stock on any date shall be, except as otherwise specifically provided, the
     average of the daily Closing Prices (as hereinafter defined) for the five
     consecutive Trading Dates (as hereinafter defined) ending on and including
     the date of determination of the Current Market Price; provided, however,
     that if the Closing Price of the Common Stock on the Trading Date next
     following such five-day period (the "next-day closing price") is less than
     95% of such average Closing Price, then the Current Market Price per share
     of Common Stock on such date of determination will be the next-day closing
     price; and provided, further, that with respect to any conversion or
     antidilution adjustment, if any event that results in an adjustment of the
     Common Equivalent Rate occurs during the period beginning on the first date
     of the applicable determination period and ending on the applicable
     conversion date, the Current Market Price as determined pursuant to the
     foregoing will be appropriately adjusted to reflect the occurrence of such
     event.

          (H)  In any case in which an adjustment as a result of any event is
     required to become effective as of the close of business on the record date
     for such event and the Mandatory Conversion Date occurs after such record
     date but before the occurrence of such event, the Corporation may in its
     sole discretion elect to defer the following until after the occurrence of
     such event (but shall be under no obligation to do so):  (1) issuing to the
     holder of any converted shares of said twelfth series the additional shares
     of Common Stock issuable upon such conversion as a result of such
     adjustment and (2) paying to such holder any amount in cash in lieu of a
     fractional share of Common Stock as hereinafter provided.

          (iii)     Whenever the Common Equivalent Rate is adjusted as herein
     provided, the Corporation shall:

                                    -5-

<PAGE>

          (A)  forthwith compute the adjusted Common Equivalent Rate in
     accordance herewith and prepare a certificate signed by the President, any
     Vice President or the Treasurer of the Corporation setting forth the
     adjusted Common Equivalent Rate, the method of calculation thereof in
     reasonable detail and the facts requiring such adjustment and upon which
     such adjustment is based, which certificate shall be conclusive, final and
     binding evidence of the correctness of the adjustment, and file such
     certificate forthwith with the transfer agent or agents for the shares of
     said twelfth series and for the Common Stock; and

          (B)  mail a notice stating that the Common Equivalent Rate has been
     adjusted, the facts requiring such adjustment and upon which such
     adjustment is based and setting forth the adjusted Common Equivalent Rate
     to the holders of record of the outstanding shares of said twelfth series
     at or prior to the time the Corporation mails an interim statement to its
     shareholders covering the fiscal quarter during which the facts requiring
     such adjustment occurred, but in any event within 45 days of the end of
     such fiscal quarter.

          (iv) No fractional shares or scrip representing fractional shares of
     Common Stock shall be issued upon the conversion of any shares of said
     twelfth series.  Instead of any fractional interest in a share of Common
     Stock which would otherwise be deliverable upon the conversion of a share
     of said twelfth series, the Corporation shall pay to the holder of such
     share an amount in cash (computed to the nearest cent) equal to the same
     fraction of the Current Market Price of the Common Stock determined as of
     the second Trading Date immediately preceding the relevant Notice Date.  If
     more than one share of any holder shall be converted at the same time, the
     number of full shares of Common Stock into which such shares shall be
     converted shall be computed on the basis of the aggregate number of shares
     so converted.

          (v)  DEFINITIONS.   As used with respect to the shares of said twelfth
     series:

          (A)  the term "business day" shall mean any day other than a Saturday,
     Sunday or a day on which banking institutions in the State of Washington or
     the State of New York are authorized or obligated by law or executive order

     otherwise;

          (B)  the term "Closing Price" on any day shall mean the reported last
     sale price regular way (with any relevant due bills attached) on such day,
     or in case no such sale takes place on such day, the average of the
     reported last bid and asked prices regular way (with any relevant due bills
     attached), in each case as reported in the composite quotations for
     securities listed on the New York Stock Exchange, or, if the Common Stock
     is not listed or admitted to trading on such Exchange, on the principal
     national securities exchange on which the Common Stock is listed or
     admitted to trading (which shall be the national securities exchange on
     which the greatest number of shares of Common Stock has been traded during
     the five consecutive Trading Dates ending on and including the date of
     determination of the Current Market Price), or, if not listed or admitted
     to trading on any national securities exchange, the average of the reported
     last bid and asked prices regular way (with any relevant due bills
     attached) of the Common Stock on the over-the-counter market on the day in
     question as reported by the National Association of Securities Dealers
     Automated Quotation System, or a similar generally accepted reporting
     service, or if no information of such character shall be  available, as
     determined in good faith by the Board of Directors on the basis of such
     relevant factors as the Board of Directors in good faith considers
     appropriate, (such determination to be conclusive, final and binding upon
     the Corporation and all shareholders of the Corporation);

     of the Corporation's capital stock or an amendment of the Restated Articles
     of Incorporation of the Corporation that results in the conversion or
     exchange of Common Stock into, or the right of the holders thereof to
     receive, in lieu of or in addition to their shares of Common Stock, other
     securities or other property (whether of the Corporation or any other
     entity);

          (D)  the term "Notice Date" with respect to any notice given by the
     Corporation in connection with a conversion of any of the Shares of said
     twelfth series shall be the date of the commencement of the mailing of such
     notice to the holders of such shares as specified herein;

          (E)  the term "Optional Conversion Premium" shall mean, in respect of

     conversion date (computed on the basis of a 360-day year consisting of
     twelve 30-day months) and equal to $0 on and after September 15, 2001;

     the date on which the Company gives notice of such conversion;

          (F)  the term "Optional Conversion Price" shall mean, in respect of
     each share of said twelfth series converted at the option of the Company, a
     number of shares of Common Stock equal to the lesser of (1) the amount of $
     ________ divided by the Current Market Price as of the close of business on
     the second Trading Date immediately preceding the date on which the Company
     gives notice of such conversion and (2) the number of shares of Common
     Stock determined by reference to the Common Equivalent Rate;

          (G)  the term "Rights Agreement" shall mean the Rights Agreement,
     dated as of February 16, 1990, between the Company and The Bank of New
     York, successor Rights Agent, as amended; and the term "Rights" shall mean
     the "Preferred Share Purchase Rights" established under the Rights
     Agreement; and

          (H)  the term "Trading Date" shall mean a date on which the New York

     conversion shall be sent to the holders of the shares of said twelfth
     series to be converted at the addresses shown on the books of the

     outstanding), (3) the conversion price, (4) the place or places where
     certificates for such shares are to be surrendered in exchange for
     certificates and/or cash representing the conversion price and (5) that

     conversion date.  Notwithstanding the foregoing, the failure so to mail any
     such notice of conversion or any defect therein or in the mailing thereof
     shall not prevent the occurrence of such conversion or impair the validity
     thereof.

                                    -7-

<PAGE>

          (B)  The shares of said twelfth series shall, on the date fixed for
     conversion, be deemed to have been converted; from and after such
     conversion date dividends shall cease to accrue on such shares; and all
     rights of the holders of such shares (except only rights as holders of
     securities into which such shares shall have been converted and the right
     to receive certificates representing such securities and the right to
     receive an amount equal to dividends accrued on such shares to the date
     fixed for such conversion) shall terminate.

        (vii)  Upon the surrender by a holder of converted shares of said
     twelfth series of certificates representing such shares in accordance with
     the notice of conversion on or after the conversion date, the Corporation
     shall deliver to or upon the order of such holder:

          (A)  certificates representing whole units of the securities into
     which such shares of said twelfth series have been converted, such
     certificates to be registered in such name or names, and to be issued in
     such denominations, as such holder shall have specified;

          (B)  an amount, in cash, in lieu of fractional shares, as hereinbefore

          (C)  an amount, in cash, equivalent to accumulated and unpaid
     dividends on such shares of Series A Preferred Stock to the conversion
     date;

          (D)  an amount, in cash, securities or other property, representing
     any other consideration to be delivered upon such conversion; and

          (E)  a certificate representing any shares of said twelfth series
     which had been represented by the certificate or certificates delivered to
     the Corporation in connection with such conversion but which were not
     converted.

     similar issue or transfer taxes payable in respect of the issue or delivery
     of shares of Common Stock or other securities on the conversion of shares
     of said twelfth series; provided, however, that the Corporation shall not
     be required to pay any tax which may be payable in respect of any
     registration of transfer involved in the issue or delivery of shares of
     Common Stock or other securities in a name other than that of the
     registered holder of the shares converted, and no such issue or delivery
     shall be made unless and until the person requesting such issue has paid to
     the Corporation the amount of any such tax or has established, to the
     satisfaction of the Corporation, that such tax has been paid.

     SECTION 1.  ANNUAL MEETING.  The Annual Meeting of Shareholders shall be 
held on such date in the month of May in each year as determined by the Board 
of Directors for the purpose of electing directors and for the transaction of 
such other business as may come before the meeting.  If the day fixed for the 
Annual Meeting shall be a legal holiday, such meeting shall be held on the 
next succeeding business day.

     SECTION 2.  SPECIAL MEETINGS.  Special meetings of the shareholders may 
be called by the President, the Chairman of the Board, the majority of the 
Board of Directors, the Executive Committee of the Board, and shall be called 
by the President at the request of the holders of not less than two-thirds 
(2/3) of the voting power of all shares of the voting stock voting together 
as a single class.  Only those matters that are specified in the call of or 
request for a special meeting may be considered or voted at such meeting.

     SECTION 3.  PLACE OF MEETING.  Meetings of the shareholders, whether 
they be annual or special, shall be held at the principal office of the 
Corporation, unless a place, either within or without the state, is otherwise 
designated by the Board of Directors in the notice provided to shareholders 
of such meetings.

     SECTION 4.  NOTICE OF MEETING.  Written or printed notice of every 
meeting of shareholders shall be mailed by the Corporate Secretary or any 
Assistant Corporate Secretary, not less than ten (10) nor more than fifty 
(50) days before the date of the meeting, to each holder of record of stock 
entitled to vote at the meeting.  The notice shall be mailed to each 
shareholder at his last known post office address, provided, however, that if

before or after the meeting, the notice of the meeting to such shareholders 
shall be unnecessary.

     SECTION 5.  VOTING OF SHARES.  At every meeting of shareholders each 
holder of stock entitled to vote thereat shall be entitled to one vote for 
each share of such stock held in his name on the books of the Corporation,

     SECTION 7.  CLOSING OF TRANSFER BOOKS OR FIXING OF RECORD DATE.  For the 
purposes of determining shareholders entitled to notice of or to vote at any 
meeting of shareholders or any adjournment thereof, or shareholders 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 of the 
Corporation may provide that the stock transfer books shall be closed for a 
stated period but not to exceed, in any case, fifty (50) days.  If the stock 
transfer books shall be closed for the purpose of determining shareholders 
entitled to notice of or to vote at a meeting of shareholders, such books 
shall be closed for at least ten (10) days immediately preceding such 
meeting.  In lieu of closing the stock transfer books, 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 seventy (70) days 
and, in case of a meeting of shareholders, not less than ten (10) days prior 
to the date on which the particular action, requiring such determination of 
shareholders, is to be taken.  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 8.  VOTING RECORD.  The officer or agent having charge of the 
stock transfer books for shares of the Corporation shall make, at least ten 
(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 ten (10) days prior to such 
meeting, shall be kept on file at the registered office of the Corporation.  
Such record 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 for the purposes thereof.

     SECTION 9.  CONDUCT OF PROCEEDINGS.  The Chairman of the Board shall 
preside at all meetings of the shareholders.  In the absence of the Chairman, 
the President shall preside and in the absence of both, the Executive Vice 
President shall preside.  The members of the Board of Directors present at 
the meeting may appoint any officer of the Corporation or member of the Board 
to act as Chairman of any meeting in the absence of the Chairman, the 
President, or Executive Vice President.  The Corporate Secretary of the 
Corporation, or in his absence, an Assistant Corporate Secretary, shall act 
as Secretary at all meetings of the shareholders.  In the absence of the 
Corporate Secretary or Assistant Corporate Secretary at any meeting of the 
shareholders, the presiding officer may appoint any person to act as 
Secretary of the meeting.

     SECTION 10.  PROXIES.  At all meetings of shareholders, a shareholder may
vote in person or by proxy executed in writing by the shareholder or by his duly
authorized attorney in fact.  Such proxy shall be filed with the Corporate
Secretary of the Corporation before or at the time of the meeting.

                                    ARTICLE III.
                                 BOARD OF DIRECTORS

     SECTION 1.  GENERAL POWERS.  The powers of the Corporation shall be 
exercised by or under the authority of the Board of Directors, except as 
otherwise provided by the laws of the State of Washington and the Articles of 
Incorporation.

     SECTION 2.  NUMBER AND TENURE.  The number of Directors of the 
Corporation shall be eight (8); provided, however, that if the right to elect 
a majority of the Board of Directors shall have accrued to the holders of the 
Preferred Stock as provided in paragraph (1) of subdivision (j) of Article 
THIRD of the Articles of Incorporation, then, during such period as such 
holders shall have such right, the number of directors may exceed eight (8).  
Directors shall be divided into three classes, as nearly equal in number as 
possible.  At each Annual Meeting of Shareholders, directors elected to 
succeed those directors whose terms expire shall be elected for a term of 
office to expire at the third succeeding Annual Meeting of Shareholders after 
their election.  Notwithstanding the foregoing, directors elected by the 
holders of the Preferred Stock in accordance with paragraph (1) of 
subdivision (j) of Article THIRD of the Articles of Incorporation shall be 
elected for a term which shall expire not later than the next Annual Meeting 
of Shareholders.  All directors shall hold office until the expiration of 
their respective terms of office and until their successors shall have been 
elected and qualified.

     SECTION 7.  QUORUM.  A majority of the number of directors shall 
constitute a quorum for the transaction of business at any meeting of the 
Board of Directors.  The action of a majority of the directors present at a 
meeting at which a quorum is present shall be the action of the Board.

     SECTION 8.  ACTION WITHOUT A MEETING.  Any action required by law to be 
taken at a meeting of the directors of the Corporation, or any action which 
may be taken at a meeting of the directors or of a committee, may be taken 
without a meeting if a consent in writing, setting forth the action so taken, 
shall be signed by all of the directors, or all of the members of the 
committee, as the case may be.  Such consent shall have the same effect as a 
unanimous vote.
     
     SECTION 9. VACANCIES.  Subject to the provisions of paragraph (1) of 
subdivision (j) of Article THIRD of the Articles of Incorporation, (a) any 
vacancy occurring in the Board of Directors may be filled by the affirmative

the Board of Directors and any director so elected to fill a vacancy shall be 
elected for the unexpired term of his or her predecessor in office and (b) 
any directorship to be filled by reason of an increase in the number of 
directors may be filled by the Board of Directors for a term of office 
continuing only until the next election of directors by the shareholders.

     SECTION 10.  RESIGNATION OF DIRECTOR.  Any director or member of any 
committee may resign at any time.  Such resignation shall be made in writing 
and shall take effect at the time specified therein.  If no time is 
specified, it shall take effect from the time of its receipt by the Corporate 
Secretary, who shall record such resignation, noting the day, hour and minute 
of its reception. The acceptance of a resignation shall not be necessary to 
make it effective.

     SECTION 11.  REMOVAL.  Subject to the provisions of paragraph (1) of 
subdivision (j) of Article THIRD of the Articles of Incorporation, any 
director may be removed from office at any time, but only for cause and only 
by the affirmative vote of the holders of at least a majority of the voting 
power of all of the shares of capital stock of the Corporation entitled 
generally to vote in the election of directors voting together as a single 
class, at a meeting of shareholders called expressly for that purpose; 
provided, however, that if less than the entire Board of Directors is to be 
removed, no one of the directors may be removed if the votes cast against the 
removal of such director would be sufficient to elect such director if then 
cumulatively voted at an election of the class of directors of which such 
director is a part.  No decrease in the number of directors constituting the 
Board of Directors shall shorten the term of any incumbent director.
     
     SECTION 12.  ORDER OF BUSINESS.  The Chairman of the Board shall preside 
at all meetings of the directors.  In the absence of the Chairman, the 
officer or member of the Board designated by the Board of Directors shall 
preside.  At meetings of the Board of Directors, business shall be transacted 
in such order as the Board may determine.  Minutes of all proceedings of the

maintained by the Corporate Secretary or an Assistant Corporate Secretary and 
the original shall be maintained in the principal office of the Corporation.

paragraph (1) of subdivision (j) of Article THIRD of the Articles of 
Incorporation, nominations for the election of directors may be made by the 
Board of Directors, or a nominating committee appointed by the Board of 
Directors, or by any holder of shares of the capital stock of the Corporation 
entitled generally to vote in the election of directors (such stock being 
hereinafter in this Section called "Voting Stock").  However, any holder of 
shares of the Voting Stock may nominate one or more persons for election as 
directors at a meeting only if written notice of such shareholder's intent to 
make such nomination or nominations has been given, either by personal 
delivery or by United States mail, postage prepaid, to the Corporate 
Secretary not later than (i) with respect to an election to be held at an 
annual meeting of shareholders, ninety (90) days in advance of such 

                                       4

of the shareholder who intends to make the nomination and of the person or 
persons to be nominated; (b) a representation that such shareholder is a 
holder of record of shares of the Voting Stock of the Corporation and intends 
to appear in person or by proxy at the meeting to nominate the person or 
persons identified in the notice; (c) a description of all arrangements or 
understandings between such shareholder and each nominee and any other person 
or persons (naming such person or persons) pursuant to which the nomination 
or nominations are to be made by such shareholder; (d) such other information 
regarding each nominee proposed by such shareholder as would be required to 
be included in a proxy statement under the Securities Exchange Act of 1934, 
as amended, and the rules and regulations thereunder (or any subsequent 
revisions replacing such Act, rules or regulations) if the nominee(s) had 
been nominated, or were intended to be nominated, by the Board of Directors; 
and (e) the consent of each nominee to serve as a Director of the Corporation 
if so elected.  The Chairman of the meeting may refuse to acknowledge the 
nomination of any person not made in compliance with the foregoing procedure.

     SECTION 14.  PRESUMPTION OF ASSENT.  A director of the Corporation who 
is present at a meeting of the Board of Directors, or of a committee thereof, 
at which action on any corporate matter is taken, shall be presumed to have 
assented to the action unless his dissent shall be entered in the minutes of 
the meeting or unless he shall file his written dissent to such action with 
the person acting as the Secretary of the meeting before the adjournment 
thereof or shall forward such dissent by registered mail to the Corporate 
Secretary of the Corporation immediately after the adjournment of the 
meeting.  Such right to dissent shall not apply to a director who voted in 
favor of such action.
     
     SECTION 15.  RETIREMENT OF DIRECTORS.  Directors who are seventy (70) 
years of age or more shall retire from the Board effective at the conclusion 
of the Annual Meeting of Shareholders held in the year in which their term 
expires, and any such Director shall not be nominated for election at such

Directors, or any member thereof, of any responsibility imposed by law.

     SECTION 2.  AUTHORITY.  The Executive Committee, when the Board of 
Directors is not in session, shall have and may exercise all of the authority 
of the Board of Directors including authority to authorize distributions or

Section 2.02, without charge to the holder.  Upon surrender for cancellation of

deliver in exchange therefor definitive Depositary Receipts representing the
same number of Depositary Shares as represented by the surrendered temporary
Depositary Receipt or Depositary Receipts.  Such exchange shall be made at the
Company's expense and without any charge to the holder thereof.  Until so

signature of a duly authorized signatory of the Depositary; provided, however,
that such signature may be a facsimile if a Registrar (other than the
Depositary) shall have countersigned the Depositary Receipts by manual signature

entitled to any benefits under this Deposit Agreement or be valid or obligatory
for any purpose unless it shall have been executed as provided in the preceding
sentence.  The Depositary shall record on its books each Depositary Receipt
executed as provided above and delivered as hereinafter provided.



                                       -3-

<PAGE>

     Except as the Depositary may otherwise determine, Depositary Receipts shall
be in denominations of any number of whole Depositary Shares.  All Depositary
Receipts shall be dated the date of their execution.

     Depositary Receipts may be endorsed with or have incorporated in the text
thereof such legends or recitals or changes not inconsistent with the provisions
of this Deposit Agreement as may be required by the Depositary or required to
comply with any applicable law or regulation or with the rules and regulations
of any securities exchange upon which the New Preferred Stock, the Depositary
Shares or the Depositary Receipts may be listed or to conform with any usage
with respect thereto, or to indicate any special limitations or restrictions to
which any particular Depositary Receipts are subject by reason of the date of
issuance of the New Preferred Stock or otherwise.

     Title to any Depositary Receipt (and to the Depositary Shares evidenced by
such Depositary Receipt) that is properly endorsed or accompanied by a properly
executed instrument of transfer or endorsement shall be transferable by delivery
with the same effect as in the case of a negotiable instrument; provided,
however, that until a Depositary Receipt shall be transferred on the books of
the Depositary as provided in Section 2.04, the Depositary may, notwithstanding
any notice to the contrary, treat the record holder thereof at such time as the
absolute owner thereof for the purpose of determining the person entitled to
distribution of dividends or other distributions or to any notice provided for
in this Deposit Agreement and for all other purposes.

     SECTION 1.022. DEPOSIT OF NEW PREFERRED STOCK; EXECUTION AND DELIVERY OF
DEPOSITARY RECEIPTS IN RESPECT THEREOF.  On the date the New Preferred Stock is
initially issued by the Company, the Depositary, upon receipt of a written order
from the Company and a certificate or certificates for the New Preferred Stock
to be deposited under this Deposit Agreement in accordance with the provisions
of this Section, shall execute and deliver a Depositary Receipt or Depositary
Receipts for the number of Depositary Shares representing such deposited New
Preferred Stock to the person or persons stated in such order.  Deposited New
Preferred Stock shall be held by the Depositary in an account to be established
by the Depositary at the Corporate Office.

     The Company shall deliver to the Depositary from time to time such
quantities of Depositary Receipts as the Depositary may reasonably request to
enable the Depositary to perform its obligations under this Deposit Agreement.

     SECTION 1.023. CONVERSIONS OF NEW PREFERRED STOCK.  Whenever the Company
shall convert New Preferred Stock into Common Stock in accordance with the
Articles of Amendment, it shall (unless otherwise agreed in writing with the
Depositary) give the Depositary in its capacity as Depositary not less than
[five] business days prior notice of the proposed date of the mailing of the
notice of conversion to be effected in connection with a conversion of New
Preferred Stock and of the number of such shares of New Preferred Stock held by
the Depositary to be converted as hereinafter provided.


                                       -4-

<PAGE>

     The Depositary shall, as directed by the Company, mail, first class postage
prepaid, the notice of the conversion of New Preferred Stock not less than 15
and not more than 60 days prior to the date fixed for conversion (the
"conversion date") of such New Preferred Stock.  Such notice shall be mailed to
each holder of record of the Depositary Receipts evidencing the Depositary
Shares, at the address of such holder as the same appears on the records of the
Depositary; but the failure to mail any such notice of conversion or any defect
therein or the mailing thereof shall not prevent the occurrence of such
conversion or impair the validity thereof.

     With respect to the notices provided in this Section 2.03, the Company
shall provide the Depositary with such notice, and each such notice shall, as
appropriate and to the extent determinable at the time of such notice, state:
the conversion date; in connection with an optional redemption, the Optional
Conversion Price, the number of shares of Common Stock deliverable upon
conversion of each share of New Preferred Stock, the Current Market Price used
to calculate the number of shares of Common Stock (subject to any subsequent
adjustments pursuant to paragraph Third of the Articles of Amendment) and the
number of shares of Common Stock to be delivered in respect of each Depositary
Share, the Optional Conversion Premium and whether the same will be paid in cash
or in shares of Common Stock and, if to be paid in shares of Common Stock, the
number of shares to be delivered in respect of each share of New Preferred Stock
and in receipt of each Depositary Share; in connection with a mandatory
conversion, the number of shares of Common Stock deliverable upon conversion of
each share of New Preferred Stock and the then effective Common Equivalent Rate
used to calculate the number of shares of Common Stock (subject to any
subsequent adjustments pursuant to paragraph Third of the Articles of Amendment)
and the number of shares of Common Stock to be delivered in respect of each
Depositary Share; the place or places where Depositary Receipts evidencing
Depositary Shares are to be surrendered for certificates and/or cash
representing the conversion price; and that dividends in respect of the New
Preferred Stock to be converted will cease to accrue on such conversion date.

     Notice having been mailed by the Depositary as aforesaid, from and after
the conversion date, the Depositary Shares shall be deemed no longer to be
outstanding and all rights of the holders of Depositary Receipts evidencing such
Depositary Shares (except the right to receive the shares of Common Stock and
any cash upon conversion) shall cease and terminate.  Upon surrender in
accordance with said notices of the Depositary Receipts evidencing such
Depositary Shares (properly endorsed or assigned for transfer, if the Depositary
shall so require), such Depositary Shares shall be exchanged for shares of
Common Stock at a rate equal to one-tenth of the number of shares of Common
Stock delivered in respect of the shares of New Preferred Stock represented by
such Depositary Shares; provided, however, that no fractional shares of Common
Stock shall be distributed.

     SECTION 2.04. TRANSFER OF DEPOSITARY RECEIPTS.  Subject to the terms and
conditions of this Deposit Agreement, the Depositary shall make transfers on its
books from time to time of Depositary Receipts upon any surrender thereof by the
holder in person

                                       -5-
<PAGE>

or by a duly authorized attorney, properly endorsed or accompanied by a 
properly executed instrument of transfer or endorsement, together with 
evidence of the payment of any transfer taxes as may be required by law.  
Upon such surrender, the Depositary shall execute a new Depositary Receipt or 
Depositary Receipts and deliver the same to or upon the order of the person 
entitled thereto evidencing the same aggregate number of Depositary Shares 
evidenced by the Depositary Receipt or Depositary Receipts surrendered.

     The Depositary shall not be required to issue, transfer or exchange any
Depositary Receipts for a period beginning at the opening of business 15 days
next preceding the date of the selection of New Preferred Stock to be converted
and ending at the close of business on the day of the mailing of notice of
conversion of New Preferred Stock.

     SECTION 2.05. COMBINATION AND SPLIT-UPS OF DEPOSITARY RECEIPTS. Upon
surrender of a Depositary Receipt or Depositary Receipts at the Corporate Office
or such other office as the Depositary may designate for the purpose of
effecting a split-up or combination of Depositary Receipts, subject to the terms
and conditions of this Deposit Agreement, the Depositary shall execute and
deliver a new Depositary Receipt or Depositary Receipts in the authorized
denominations requested evidencing the same aggregate number of Depositary
Shares evidenced by the Depositary Receipt or Depositary Receipts surrendered;
provided, however, that the Depositary shall not issue any Depositary Receipt
evidencing  fractional Depositary Shares.

     SECTION 2.06. SURRENDER OF DEPOSITARY RECEIPTS AND WITHDRAWAL OF NEW
PREFERRED STOCK.  Any holder of a Depositary Receipt or Depositary Receipts may
withdraw any or all of the New Preferred Stock (but only whole shares)
represented by the Depositary Shares evidenced by such Depositary Receipts by
surrendering such Depositary Receipt or Depositary Receipts at the Corporate
Office or at such other office as the Depositary may designate for such
withdrawals.  After such surrender, without unreasonable delay, the Depositary
shall deliver to such holder, or to the person or persons designated by such
holder as hereinafter provided, the whole number of shares of New Preferred
Stock represented by the Depositary Shares evidenced by the Depositary Receipt
or Depositary Receipts so surrendered.  Delivery of the New Preferred Stock
being withdrawn may be made by the delivery of such certificates, documents of
title and other instruments as the Depositary may deem appropriate, which, if
required by the Depositary, shall be properly endorsed or accompanied by proper
instruments of transfer.

     Holders of a Depositary Receipt or Depositary Receipts who withdraw New
Preferred Stock will not thereafter be entitled to deposit such shares of New
Preferred Stock hereunder or to receive Depositary Shares therefor.  If, prior
to a conversion, the Depositary Receipt or Depositary Receipts delivered by the
holder to the Depositary in connection with such withdrawal shall evidence a
number of Depositary Shares in excess of the number of Depositary Shares
representing the whole number of shares of New Preferred Stock to be withdrawn,
the Depositary shall at the same time, in addition to such whole number of
shares of New Preferred Stock, deliver to such holder, or (subject to Section
2.04) upon his order,

                                       -6-
<PAGE>

a new Depositary Receipt or Depositary Receipts evidencing such excess number 
of Depositary Shares.

     To the extent that Depositary Receipts are surrendered and all shares of
New Preferred Stock which would otherwise be distributed cannot be distributed
to the record holder of Depositary Receipts without creating fractional
interests in such shares of New Preferred Stock or, the Depositary may, with the
consent of the Company, adopt such method as it deems equitable and practicable
for the purpose of effecting such distribution, including the sale (at public or
private sale) of such shares of New Preferred Stock representing in the
aggregate such fractional interests at such place or places and upon such terms
as it may deem proper, and the net proceeds of any such sale shall, subject to
Section 3.02, be distributed or made available for distribution to such record
holders that would otherwise receive fractional interests in such shares of New
Preferred Stock.

     If the New Preferred Stock being withdrawn is to be delivered to a person
or persons other than the registered holder of the Depositary Receipt or
Depositary Receipts being surrendered for withdrawal of such New Preferred
Stock, such holder shall execute and deliver to the Depositary a written order
so directing the Depositary and the Depositary may require that the Depositary
Receipt or Depositary Receipts surrendered by such holder for withdrawal of such
shares of New Preferred Stock be properly endorsed in blank or accompanied by a
properly executed instrument of transfer or endorsement in blank.

     The Depositary shall deliver the New Preferred Stock represented by the
Depositary Shares evidenced by Depositary Receipts surrendered for withdrawal at
the Corporate Office, except that, at the request, risk and expense of the
holder surrendering such Depositary Receipt or Depositary Receipts and for the
account of the holder thereof, such delivery may be made at such other place as
may be designated by such holder.

     SECTION 2.07. LIMITATIONS ON EXECUTION AND DELIVERY, TRANSFER, SPLIT-UP,
COMBINATION, SURRENDER AND EXCHANGE OF DEPOSITARY RECEIPTS.  As a condition
precedent to the execution and delivery, transfer, split-up, combination,
surrender or exchange of any Depositary Receipt, the Depositary, any of the
Depositary's Agents or the Company may require any or all of the following: (i)
payment to it of a sum sufficient for the payment (or, in the event that the
Depositary or the Company shall have made such payment, the reimbursement to it)
of any tax or other governmental charge with respect thereto (including any such
tax or charge with respect to the New Preferred Stock being withdrawn or with
respect to the Common Stock of the Company being issued upon conversion); (ii)
the production of proof satisfactory to it as to the identity and genuineness of
any signature; and (iii) compliance with such regulations, if any, as the
Depositary or the Company may establish not inconsistent with the provisions of
this Deposit Agreement.

     The transfer of Depositary Receipts may be refused and the transfer, 
split-up, combination, surrender or exchange of outstanding Depositary 
Receipts may be suspended (i) during a period when the register of 
shareholders of the Company is closed, (ii) if any such

                                       -7-
<PAGE>

action is deemed necessary or advisable by the Depositary, any of the 
Depositary's Agents or the Company at any time or from time to time because 
of any requirement of law or of any government or governmental body or 
commission, or under any provision of this Deposit Agreement, or (iii) with 
the approval of the Company, for any other reason.

     SECTION 2.08. LOST DEPOSITARY RECEIPTS, ETC.  In case any Depositary
Receipt shall be mutilated or destroyed or lost or stolen, the Depositary in its
discretion may execute and deliver a Depositary Receipt of like form and tenor
in exchange and substitution for such mutilated Depositary Receipt or in lieu of
and in substitution for such destroyed, lost or stolen Depositary Receipt;
provided, however, that the holder thereof provides the Depositary with (i)
evidence satisfactory to the Depositary of such destruction, loss or theft of
such Depositary Receipt, of the authenticity thereof and of his ownership
thereof, (ii) reasonable indemnification satisfactory to the Depositary and
(iii) payment of any expense (including fees, charges and expenses of the
Depositary) in connection with such indemnification, execution and delivery.

     SECTION 2.09. CANCELLATION AND DESTRUCTION OF SURRENDERED DEPOSITARY
RECEIPTS.  All Depositary Receipts surrendered to the Depositary or any
Depositary's Agent shall be canceled by the Depositary.  Except as prohibited by
applicable law or regulation, the Depositary is authorized to destroy such
Depositary Receipts so canceled.

                                     ARTICLE III.

                            CERTAIN OBLIGATIONS OF HOLDERS
                        OF DEPOSITARY RECEIPTS AND THE COMPANY

     SECTION 3.01. FILING PROOFS, CERTIFICATES AND OTHER INFORMATION.  Any
holder of a Depositary Receipt may be required from time to time to file such
proof of residence or other information, to execute such certificates and to
make such representations and warranties as the Depositary or the Company may
reasonably deem necessary or proper.  The Depositary or the Company may withhold
or delay the delivery of any Depositary Receipt, the transfer, conversion or
exchange of any Depositary Receipt, the withdrawal of the New Preferred Stock
represented by the Depositary Shares evidenced by any Depositary Receipt or the
distribution of any dividend or other distribution until such proof or other
information is filed, such certificates are executed or such representations and
warranties are made.

     SECTION 3.02. PAYMENT OF TAXES OR OTHER GOVERNMENTAL CHARGES.  If any tax
or other governmental charge shall become payable by or on behalf of the
Depositary with respect to any Depositary Receipt, the Depositary Shares
evidenced by such Depositary Receipt, the New Preferred Stock (or any fractional
interest therein) represented by such Depositary Shares or any transaction
referred to in Section 4.06, such tax (including transfer, issuance or
acquisition taxes, if any) or governmental charge shall be payable by the holder

                                       -8-
<PAGE>

of such Depositary Receipt.  Until such payment is made, transfer of any
Depositary Receipt or any withdrawal of the New Preferred Stock represented by
the Depositary Shares evidenced by such Depositary Receipt may be refused and
any dividend or other distribution may be withheld.  Any dividend or other
distribution so withheld may be applied to any payment of such tax or other
governmental charge, the holder of such Depositary Receipt remaining liable for
any deficiency.  Unless the Company determines otherwise, the Depositary shall
act as the withholding agent for any payments, distributions and exchanges made
with respect to the Depositary Shares and Depositary Receipts, and the New
Preferred Stock represented thereby (collectively, the "Securities").  The
Depositary shall be responsible with respect to the Securities for the timely
(i) collection and deposit of any required withholding or backup withholding
tax, and (ii) filing of any information returns or other documents with federal
(and other applicable) taxing authorities.  In the event the Depositary is
required to pay any such amounts, the Company shall reimburse the Depositary for
payment thereof upon the request of the Depositary and the Depositary shall,
upon the Company's request and as instructed by the Company, pursue its rights
against such holder at the Company's expense.

     SECTION 3.03. REPRESENTATIONS AND WARRANTIES AS TO NEW PREFERRED STOCK.
The Company hereby represents and warrants that the New Preferred Stock has been
validly issued and is fully paid and nonassessable and that the Company is duly
authorized to deposit the New Preferred Stock.  Such representations and
warranties shall survive the deposit of the New Preferred Stock and the issuance
of Depositary Receipts.

                                     ARTICLE IV.

                           THE NEW PREFERRED STOCK, NOTICES

     SECTION 4.01. CASH DISTRIBUTIONS.  Whenever any cash dividend or other
cash distribution shall be paid on the New Preferred Stock, the Company, on
behalf of the Depositary, (or, if the Company determines otherwise, the
Depositary) shall, subject to Sections 3.01 and 3.02, distribute on the payment
date to record holders of Depositary Receipts on the record date fixed pursuant
to Section 4.04 such amounts of such sum as are, as nearly as practicable, in
proportion to the respective numbers of Depositary Shares evidenced by the
Depositary Receipts held by such holders; provided, however, that in case the
Company or the Depositary shall be required to withhold and does withhold from
any cash dividend or other cash distribution in respect of the New Preferred
Stock an amount on account of taxes or as otherwise required pursuant to law,
regulation or court process, the amount made available for distribution or
distributed in respect of Depositary Shares shall be reduced accordingly.  The
Company, on behalf of the Depositary, (or, if the Company determines otherwise,
the Depositary) shall distribute or make available for distribution, as the case
may be, only such amount, however, as can be distributed without attributing to
any owner of Depositary Shares a fraction of one cent.  In the event that the
calculation of any such cash dividend or other cash distribution to be paid to
any record holder on the aggregate

                                       -9-
<PAGE>

number of Depositary Shares held by such holder results in an amount which is 
a fraction of a cent, the amount the Depositary shall distribute to such 
record holder shall be rounded to the next highest whole cent; and upon 
request of the Depositary, the Company shall pay the additional amount to the 
Depositary for distribution.

     SECTION 4.02. DISTRIBUTIONS OTHER THAN CASH.  Whenever any distribution
other than cash shall be made on the New Preferred Stock, the Company, on behalf
of the Depositary (or, if the Company determines otherwise, the Depositary)
shall, subject to Sections 3.01 and 3.02, distribute on the payment date to
record holders of Depositary Receipts on the record date fixed pursuant to
Section 4.04 such amounts of the securities or property received by it as are,
as nearly as practicable, in proportion to the respective numbers of Depositary
Shares evidenced by the Depositary Receipts held by such holders, in any manner
that the Company may deem equitable and practicable for accomplishing such
distribution.  If, in the opinion of the Company, such distribution cannot be
made proportionately among such record holders, or if for any other reason
(including any requirement that the Company or the Depositary withhold an amount
on account of taxes or as otherwise required pursuant to law, regulation or
court process), the Company deems such distribution not to be feasible, the
Company, on behalf of the Depositary (or, if the Company determines otherwise,
the Depositary) may adopt such method as it deems equitable and appropriate for
the purpose of effecting such distribution, including the sale (at public or
private sale) of the securities or property thus received, or any part thereof,
at such place or places and upon such terms as it may deem proper.  The net
proceeds of any such sale shall, subject to Sections 3.01 and 3.02, be
distributed or made available for distribution, as the case may be, by the
Company, on behalf of the Depositary (or, if the Company determines otherwise,
the Depositary) to record holders of Depositary Receipts as provided by Section
4.01 in the case of a distribution received in cash.

     SECTION 4.03. SUBSCRIPTION RIGHTS, PREFERENCES OR PRIVILEGES.  If the
Company shall at any time offer or cause to be offered to the persons in whose
names New Preferred Stock is registered on the books of the Company any rights,
preferences or privileges to subscribe for or to purchase any securities or any
rights, preferences or privileges of any other nature, such rights, preferences
or privileges shall in each such instance be made available by the Depositary or
the Company to the record holders of Depositary Receipts if the Company so
directs in such manner as the Company shall instruct (including by the issue to
such record holders of warrants representing such rights, preferences or
privileges); provided, however, that (a) if at the time of issue or offer of any
such rights, preferences or privileges the Company determines that it is not
lawful or feasible to make such rights, preferences or privileges available to
some or all holders of Depositary Receipts (by the issue of warrants or
otherwise) or (b) if and to the extent instructed by holders of Depositary
Receipts who do not desire to exercise such rights, preferences or privileges,
the Depositary shall then, if so instructed by the Company, and if applicable
laws or the terms of such rights, preferences or privileges so permit, sell such
rights, preferences or privileges of such holders at public or private sale, at
such place or places and upon such terms as it may deem proper.  The net
proceeds of any such sale shall, subject to Sections

                                       -10-
<PAGE>

3.01 and 3.02, be distributed by the Depositary or the Company, as the case 
may be, to the record holders of Depositary Receipts entitled thereto as 
provided by Section 4.01 in the case of a distribution received in cash.

     If registration under the Securities Act of the securities to which any
rights, preferences or privileges relate is required in order for holders of
Depositary Receipts to be offered or sold such securities, the Company shall
promptly file a registration statement pursuant to the Securities Act with
respect to such rights, preferences or privileges and securities and use its
best efforts and take all steps available to it to cause such registration
statement to become effective sufficiently in advance of the expiration of such
rights, preferences or privileges to enable such holders to exercise such
rights, preferences or privileges.  In no event shall the Depositary make
available to the holders of Depositary Receipts any right, preference or
privilege to subscribe for or to purchase any securities unless and until the
Depositary has been notified by the Company that such registration statement has
become effective or that the offering and sale of such securities to such
holders are exempt from registration under the provisions of the Securities Act.

     If any other action under the law of any jurisdiction or any governmental
or administrative authorization, consent or permit is required in order for such
rights, preferences or privileges to be made available to holders of Depositary
Receipts, the Company will use its best efforts to take such action or obtain
such authorization, consent or permit sufficiently in advance of the expiration
of such rights, preferences or privileges to enable such holders to exercise
such rights, preferences or privileges.

     SECTION 4.04. NOTICE OF DIVIDENDS, FIXING OF RECORD DATE FOR HOLDERS OF
DEPOSITARY RECEIPTS.  Whenever (i) any cash dividend or other cash distribution
shall become payable, any distribution other than cash shall be made, or any
rights, preferences or privileges shall at any time be offered with respect to
the New Preferred Stock, or (ii) the Depositary shall receive notice of any
meeting at which holders of New Preferred Stock are entitled to vote or of which
holders of New Preferred Stock are entitled to notice or any solicitation of
consents in respect of the New Preferred Stock, or any event of which holders of
New Preferred Stock are entitled to notice in accordance with the Articles of
Amendment, the Depositary shall in each such instance fix a record date (which
shall be the same date as the record date fixed by the Company with respect to
the New Preferred Stock) for the determination of the holders of Depositary
Receipts (x) who shall be entitled to receive such dividend, distribution,
rights, preferences or privileges or the net proceeds of the sale thereof, (y)
who shall be entitled to receive notice of, and to give instructions for the
exercise of voting rights at, or the delivery of consents with respect to, any
such meeting or consent solicitation, as the case may be, or (z) who shall be
entitled to receive notice of any conversion or other event.

     SECTION 4.05. VOTING RIGHTS.  Promptly upon receipt of notice of any
meeting at which the holders of New Preferred Stock are entitled to vote, the
Depositary (unless another arrangement for allowing holders of Depositary Shares
to exercise the voting

                                       -11-
<PAGE>

rights associated with the Depositary Shares is agreed by the Company and the 
Depositary), shall mail to the record holders of Depositary Receipts a 
notice, which shall be provided by the Company and which shall contain (i) 
such information as is contained in such notice of meeting, (ii) a statement 
that the holders of Depositary Receipts at the close of business on a 
specified record date fixed pursuant to Section 4.04 will be entitled, 
subject to any applicable provision of law, the Restated Articles of 
Incorporation or the Articles of Amendment, to instruct the Depositary as to 
the exercise of the voting rights with respect to the number of shares of New 
Preferred Stock represented by their respective Depositary Shares and (iii) a 
brief statement as to the manner in which such instructions may be given.  
Upon the written request of a holder of a Depositary Receipt on such record 
date, the Depositary shall endeavor insofar as practicable to vote or cause 
to be voted with respect to the amount of New Preferred Stock represented by 
the Depositary Shares evidenced by such Depositary Receipt in accordance with 
the instructions set forth in such request.  The Depositary will abstain from 
voting with respect to the New Preferred Stock to the extent that it does not 
receive specific instructions from the holders of Depositary Receipts.

     SECTION 4.06. CHANGES AFFECTING NEW PREFERRED STOCK AND RECLASSIFICATIONS,
RECAPITALIZATIONS, ETC.  Upon any conversion, split-up, consolidation or any
other reclassification of New Preferred Stock, or upon any recapitalization,
reorganization, merger, amalgamation or consolidation affecting the Company or
to which it is a party or sale of all or substantially all of the Company's
assets, the Depositary shall, upon the instructions of the Company, treat any
shares of stock or other securities (including depositary shares) or property
(including cash) that shall be received by the Depositary in exchange for or
upon conversion of or in respect of the New Preferred Stock as new deposited
property under this Deposit Agreement, and Depositary Receipts then outstanding
shall thenceforth represent the proportionate interests of holders thereof in
the new deposited property so received in exchange for or upon conversion of or
in respect of such New Preferred Stock.  In any such case the Depositary may, in
its discretion, with the approval of the Company, execute and deliver additional
Depositary Receipts, or may call for the surrender of all outstanding Depositary
Receipts to be exchanged for new Depositary Receipts specifically describing
such new deposited property.  If upon any conversion, split-up, consolidation or
any other reclassification of New Preferred Stock, or upon any recapitalization,
reorganization, merger, amalgamation or consolidation affecting the Company or
to which it is a party or sale of all or substantially all of the Company's
assets the Company delivers to the Depositary shares of stock or other
securities (including depositary shares) or property (including cash) a portion
of which is to be distributed to record holders of Depositary Receipts in
accordance with Sections 4.01, 4.02 and 4.03 and a portion of which is to be
received by the Depositary in exchange for or upon conversion of or in respect
of the New Preferred Stock as new deposited property under this Section 4.06,
the Company shall clearly indicate such division in the instructions to the
Depositary provided pursuant to this Section 4.06.

                            THE DEPOSITARY AND THE COMPANY

     SECTION 5.01. MAINTENANCE OF OFFICES, AGENCIES, TRANSFER BOOKS BY THE
DEPOSITARY; THE REGISTRAR.  Upon execution of this Deposit Agreement in
accordance with its terms, the Depositary shall maintain at the Corporate Office
facilities for the execution and delivery, transfer, surrender and exchange,
split-up and combination of Depositary Receipts and the deposit and withdrawal
of New Preferred Stock and Common Stock and at the offices of the Depositary's
Agents, if any, facilities for the delivery, transfer, surrender and exchange,
split-up, combination and conversion of Depositary Receipts and the deposit and
withdrawal of New Preferred Stock and Common Stock, all in accordance with the
provisions of this Deposit Agreement.

     The Depositary shall keep books at the Corporate Office for the
registration and transfer of Depositary Receipts, which books at all reasonable
times shall be open for inspection by the record holders of Depositary Receipts
as and to the extent provided by applicable law.  The Depositary shall consult
with the Company upon receipt of any request for inspection.  The Depositary may
close such books, at any time or from time to time, when deemed expedient by it
in connection with the performance of its duties hereunder.

     The Depositary shall make available for inspection by holders of Depositary
Receipts at the Corporate Office and at such other places as it may from time to
time deem advisable during normal business hours any reports and communications
received from the Company that are both received by the Depositary as the holder
of New Preferred Stock and made generally available to the holders of New
Preferred Stock.

     Promptly upon request from time to time by the Company and at the Company's
sole expense, the Depositary shall furnish to it a list, as of a recent date, of
the names, addresses and holdings of Depositary Shares of all persons in whose
names Depositary Receipts are registered on the books of the Depositary.

     If the Depositary Receipts or the Depositary Shares evidenced thereby or
the New Preferred Stock represented by such Depositary Shares shall be listed on
the New York Stock Exchange (the "NYSE"), the Depositary shall, if directed by
the Company, appoint a Registrar for registry of such Depositary Receipts or
Depositary Shares in accordance with the requirements of the NYSE.  Such
Registrar (which may be the Depositary if so permitted by the requirements of
the NYSE) may be removed and a substitute registrar appointed by the Depositary
upon the request or with the approval of the Company.  If the Depositary
Receipts, the Depositary Shares or the New Preferred Stock are listed on one or
more other stock exchanges, the Depositary will, at the request of the Company,
arrange such facilities for the delivery, transfer, surrender and exchange of
such Depositary Receipts, such Depositary Shares or such New Preferred Stock as
may be required by law or applicable stock exchange regulations.

     SECTION 5.02. LIABILITY OF THE DEPOSITARY, THE DEPOSITARY'S AGENTS OR THE
COMPANY.  Neither the Depositary nor any Depositary's Agent nor the Company
shall incur any liability to any holder of any Depositary Receipt, if by reason
of any provision of any present or future law or regulation thereunder of the
United States of America or of any other governmental authority or, in the case
of the Depositary or the Depositary's Agent, by reason of any provision, present
or future, of the Restated Articles of Incorporation or the Articles of
Amendment or, in the case of the Company, the Depositary or the Depositary's
Agent, by reason of any act of God or war or other circumstances beyond the
control of the relevant party, the Depositary, any Depositary's Agent or the
Company shall be prevented or forbidden from doing or performing any act or
thing that the terms of this Deposit Agreement provide shall be done or
performed; nor shall the Depositary, any Depositary's Agent or the Company incur
any liability to any holder of a Depositary Receipt by reason of any
nonperformance or delay, caused as aforesaid, in the performance of any act or
thing that the terms of this Deposit Agreement provide shall or may be done or
performed, or by reason of any exercise of, or failure to exercise, any
discretion provided for in this Deposit Agreement except, in case of any such
exercise or failure to exercise discretion not caused as aforesaid, if caused by
the negligence, bad faith or willful misconduct of the party charged with such
exercise or failure to exercise.

     SECTION 5.03. OBLIGATIONS OF THE DEPOSITARY, THE DEPOSITARY'S AGENTS AND
THE COMPANY.  Neither the Depositary nor any Depositary's Agent nor the Company
nor the Registrar assumes any obligation or shall be subject to any liability
under this Deposit Agreement or any Depositary Receipt to holders of Depositary
Receipts other than that each of them agrees to use good faith in the
performance of such duties as are specifically set forth in this Deposit
Agreement and other than for its negligence, bad faith or willful misconduct.

     Neither the Depositary nor any Depositary's Agent nor the Company nor the
Registrar shall be under any obligation to appear in, prosecute or defend any
action, suit or other proceeding with respect to New Preferred Stock, Depositary
Shares or Depositary Receipts or Common Stock or other securities or property
that in its opinion may involve it in expense or liability, unless indemnity
satisfactory to it against all expense and liability be furnished as often as
may be required.

     Neither the Depositary nor any Depositary's Agent nor the Company nor the
Registrar shall be liable for any action or any failure to act by it in reliance
upon the advice of or information from legal counsel, accountants, any holder of
a Depositary Receipt or any other person believed by it in good faith to be
competent to give such advice or information.  The Depositary, any Depositary's
Agent, the Registrar and the Company may each rely and shall each be protected
in acting upon any written notice, request, direction or other document believed
by it to be genuine and to have been signed or presented by the proper party or
parties.

                                       -14-
<PAGE>

     Notwithstanding the first paragraph of this Section 5.03, the Depositary
shall not be responsible for any failure to carry out any instruction to vote
any of the deposited shares of New Preferred Stock or for the manner or effect
of any such vote made, as long as any such action or non-action is in good faith
or in accordance with this Deposit Agreement.  The Depositary undertakes, and
any Registrar shall be required to undertake, to perform such duties and only
such duties as are specifically set forth in this Deposit Agreement with respect
to the Depositary or any Registrar.  The Depositary will indemnify the Company
against any liability that may arise out of acts performed or omitted by the
Depositary or its agents due to its or their negligence, bad faith or willful
misconduct.  The Depositary, its parent, affiliates or subsidiaries and any
Depositary's Agent may own, buy, sell or deal in any class of securities of the
Company and its affiliates and in Depositary Receipts or Depositary Shares or
become pecuniarily interested in any transaction in which the Company or its
affiliates may be interested or contract with or lend money to or otherwise act
as fully or as freely as if it were not the Depositary or the Depositary's Agent
hereunder.  The Depositary may also act as transfer agent or registrar of any of
the securities of the Company and its affiliates or act in any other capacity
for the Company or its affiliates.

     It is intended that neither the Depositary nor any Depositary's Agent shall
be deemed to be an "issuer" of the securities under the federal securities laws
or applicable state securities laws, it being expressly understood and agreed
that the Depositary and any Depositary's Agent are acting only in a ministerial
capacity as Depositary for the New Preferred Stock.

     The Depositary agrees to comply with all information reporting and
withholding requirements applicable to it under law or this Deposit Agreement in
its capacity as Depositary.

     Each of the Company and the Depositary agree to be bound by, and act in
accordance with, the Operating Guidelines current from time to time.

     The Depositary shall not lend any securities, cash or other property on
deposit under this agreement.

     Neither the Depositary (or its officers, directors, employees or agents)
nor any Depositary's Agent nor the Registrar makes any representation or has any
responsibility as to the validity of the Prospectus pursuant to which the
Depositary Shares are offered, the New Preferred Stock, the Depositary Shares or
the Depositary Receipts (except its countersignature thereon), or any
instruments referred to therein or herein, or as to the correctness of any
statement made therein or herein; provided, however, that the Depositary is
responsible for its representations in this Deposit Agreement.

     The Depositary assumes no responsibility for the correctness of the
description that appears in the Depositary Receipts, which can be taken as a
statement of the Company summarizing certain provisions of this Deposit
Agreement.  Notwithstanding any other

                                       -15-
<PAGE>

provision herein or in the Depositary Receipts, the Depositary makes no 
warranties or representations as to the validity, genuineness or sufficiency 
of any New Preferred Stock at any time deposited with the Depositary 
hereunder or of the Depositary Shares, as to the validity or sufficiency of 
this Deposit Agreement, as to the value of the Depositary Shares or as to any 
right, title or interest of the record holders of Depositary Receipts in and 
to the Depositary Shares, except that the Depositary hereby represents and 
warrants as follows: (i) the Depositary has been duly organized and is 
validly existing and in good standing under the laws of the State of New 
York, with full power, authority and legal right under such law to execute, 
deliver and carry out the terms of this Deposit Agreement; (ii) this Deposit 
Agreement has been duly authorized, executed and delivered by the Depositary; 
and (iii) this Deposit Agreement constitutes a valid and binding obligation 
of the Depositary, enforceable against the Depositary in accordance with its 
terms, except as enforcement thereof may be limited by bankruptcy, 
insolvency, reorganization or other similar laws affecting enforcement of 
creditors, rights generally and except as enforcement thereof is subject to 
general principles of equity (regardless of whether enforcement is considered 
in a proceeding in equity or at law).  The Depositary shall not be 
accountable for the use or application by the Company of the Depositary 
Shares or the Depositary Receipts or the proceeds thereof.

     SECTION 5.04. RESIGNATION AND REMOVAL OF THE DEPOSITARY, APPOINTMENT OF
SUCCESSOR DEPOSITARY.  The Depositary may at any time resign as Depositary
hereunder by notice of its election to do so delivered to the Company, such
resignation to take effect upon the appointment of a successor depositary and
its acceptance of such appointment as hereinafter provided.

     The Company may, by notice in writing to the Depositary, terminate the
engagement of the Depositary with respect to any or all of the duties or
obligations of the Depositary set out in this Deposit Agreement (including such
duties as are customarily associated with the role of a transfer agent or paying
agent), such termination to take effect upon the appointment of a successor to
fulfill those duties or obligations and its acceptance of such appointment as
hereinafter provided.  In the event that the Company terminates the engagement
of the Depositary with respect to some, but not all, of the duties or
obligations of the Depositary, the Depositary shall thereafter be deemed only to
have such rights and obligations under this Deposit Agreement as are necessary
for it to fulfill its remaining duties or obligations.  The Depositary agrees to
cooperate with the Company or any person appointed by the Company or that person
with respect to the performance of any of the duties previously performed by the
Depositary.

     In case at any time the Depositary acting hereunder shall resign or the
Company shall terminate the engagement of the Depositary with respect to any or
all of the duties or obligations of the Depositary set out in this Deposit
Agreement, the Company shall, within 45 days after the delivery of the notice of
resignation or termination, as the case may be, appoint a successor with respect
to such duties and obligations so terminated.  If such successor is to take
title to the New Preferred Stock (a "Depositary Successor"), the Depositary
Successor shall be a bank or trust company, or an affiliate of a bank or trust

                                       -16-
<PAGE>

company, having its principal office in the United States of America and having
a combined capital and surplus of at least $50,000,000.  If a successor shall
not have been appointed in 45 days, the resigning Depositary may petition a
court of competent jurisdiction to appoint a successor.

     Every Depositary Successor shall execute and deliver to its predecessor and
to the Company an instrument in writing accepting its appointment hereunder, and
thereupon such Depositary Successor, without any further act or deed, shall
become fully vested with all the duties and obligations of its predecessor so
terminated and all rights and powers with respect thereto and for all purposes
shall be the Depositary under this Deposit Agreement with respect to the duties
and obligations of the predecessor so terminated, and such predecessor, upon
payment of all sums due it and on the written request of the Company, shall
promptly execute and deliver an instrument transferring to such Depositary
Successor all such rights and powers of such predecessor hereunder, shall, if
applicable, duly assign, transfer and deliver all rights, title and interest in
the New Preferred Stock and any moneys or property held hereunder to such
Depositary Successor and shall, if applicable, deliver to such Depositary
Successor a list of the record holders of all outstanding Depositary Receipts.
Any Depositary Successor shall promptly mail notice of its appointment to the
record holders of Depositary Receipts.

     Any corporation into or with which the Depositary may be merged,
consolidated or converted shall be the successor of such Depositary without the
execution or filing of any document or any further act.  Such successor
depositary may execute the Depositary Receipts either in the name of the
predecessor depositary or in the name of the successor depositary.

     SECTION 5.05. CORPORATE NOTICES AND REPORTS.  The Company agrees that it
will deliver to the Depositary, and the Depositary will, promptly after receipt
thereof, transmit to the record holders of Depositary Receipts, in each case at
the address recorded in the Depositary's books, copies of all notices and
reports (including financial statements) required by law, by the rules of any
national securities exchange upon which the New Preferred Stock, the Depositary
Shares or the Depositary Receipts are listed or by the Restated Articles of
Incorporation and the Articles of Amendment to be furnished by the Company to
holders of New Preferred Stock.  Such transmission will be at the Company's
expense and the Company will provide the Depositary with such number of copies
of such documents as the Depositary may reasonably request.  In addition, the
Depositary will transmit to the record holders of Depositary Receipts at the
Company's expense such other documents as may be requested by the Company.  The
Depositary will make available for inspection by holders of Depositary Receipts
at the Corporate Office and at such other places as it may from time to time
deem advisable during normal business hours any such notices and reports
received from the Company.

     SECTION 5.06. TRUST PROPERTY HELD FOR BENEFIT OF HOLDERS OF DEPOSITARY
RECEIPTS.  The New Preferred Stock, the Common Stock into which the New
Preferred Stock

                                       -17-
<PAGE>

shall be converted and any cash or other property received by the Depositary 
in respect of the New Preferred Stock and/or such Common Stock shall be held 
by the Depositary, in accordance with the provisions of this Deposit 
Agreement, for the benefit of the holders from time to time of the Depositary 
Receipts, and the Company shall have no right, title or interest therein.

     SECTION 5.07. INDEMNIFICATION BY THE COMPANY.  The Company agrees to
indemnify the Depositary, any Depositary's Agent and any Registrar against, and
hold each of them harmless from, any liability, costs and expenses (including
reasonable attorneys' fees) that may arise out of or in connection with its
acting as Depositary, Depositary's Agent or Registrar, respectively, under this
Deposit Agreement and the Depositary Receipts, except for any liability arising
out of negligence, bad faith or willful misconduct on the part of any such
person or persons.

     SECTION 5.08. FEES, CHARGES AND EXPENSES.  No fees, charges and expenses
of the Depositary or any Depositary's Agent hereunder or of any Registrar shall
be payable by any person other than the Company, except for any taxes and other
governmental charges and except as provided in this Deposit Agreement.  If the
Depositary incurs fees, charges or expenses for which it is not otherwise liable
hereunder at the election of a holder of a Depositary Receipt or other person,
such holder or other person will be liable for such fees, charges and expenses.
All other fees, charges and expenses of the Depositary and any Depositary's
Agent hereunder and of any Registrar (including, in each case, fees and expenses
of counsel) incident to the performance of their respective obligations
hereunder will be paid from time to time upon consultation and agreement between
the Depositary and the Company as to the amount and nature of such fees, charges
and expenses.

                                     ARTICLE VI.

                              AMENDMENT AND TERMINATION

     SECTION 6.01. AMENDMENT.  The form of the Depositary Receipts and any
provision of this Deposit Agreement may at any time and from time to time be
amended by agreement between the Company and the Depositary in any respect that
they may deem necessary or desirable.  Any amendment that shall impose or
increase any fees, taxes or charges upon holders of Depositary Receipts (other
than fees and charges provided for herein or in the Depositary Receipts), or
that shall otherwise prejudice any substantial existing right of holders of
Depositary Receipts, shall not become effective as to outstanding Depositary
Receipts until the expiration of 30 days after notice of such amendment shall
have been given to the record holders of outstanding Depositary Receipts.  Every
holder of an outstanding Depositary Receipt at the time any such amendment
becomes effective shall be deemed, by continuing to hold such Depositary
Receipt, to consent and agree to such amendment and to be bound by this Deposit

subject to the provisions of Sections 2.03, 2.06, 2.07 and Article III, of any

owner of any Depositary Shares to surrender the Depositary Receipt evidencing 
such Depositary Shares with instructions to the Depositary to deliver to the 
holder the New Preferred Stock or Common Stock, as applicable, represented 
thereby, except in order to comply with mandatory provisions of applicable 
law.

     SECTION 6.02. TERMINATION.  This Deposit Agreement may be terminated by
the Company or the Depositary only after (i) all the outstanding New Preferred
Stock has been converted as contemplated in Section 2.03 or (ii) there shall
have been made a final distribution in respect of the New Preferred Stock (or
the Common Stock into which the New Preferred Stock shall have been converted)
in connection with any liquidation, dissolution or winding up of the Company and
such distribution shall have been made to the holders of Depositary Shares
pursuant to Section 4.01 or 4.02 as applicable.  The Company and the Depositary
shall undertake to terminate this Deposit Agreement as soon as reasonably
practicable after any such conversion or distribution.

     If any Depositary Receipts shall remain outstanding after the date of
termination of this Deposit Agreement, the Depositary thereafter shall
discontinue the transfer of Depositary Receipts, the Company or the Depositary,
as the case may be, shall suspend the distribution of dividends to the holders
thereof, and the Depositary shall not give any further notices (other than
notice of such termination) or perform any further acts under this Deposit
Agreement, except that the Depositary shall, if applicable, continue to collect
dividends and other distributions pertaining to New Preferred Stock, sell
rights, preferences or privileges as provided in this Deposit Agreement and
shall continue to deliver the New Preferred Stock and any money and other
property represented by Depositary Receipts upon surrender thereof by the
holders thereof. At any time after the expiration of two years from the date of
termination, the Depositary may sell New Preferred Stock then held hereunder at
public or private sale, at such places and upon such terms as it deems proper
and may thereafter hold the net proceeds of any such sale, together with any
money and other property held by it hereunder, without liability for interest,
for the benefit, pro rata in accordance with their holdings, of the holders of
Depositary Receipts that have not theretofore been surrendered.  After making
such sale, the Depositary shall be discharged from all obligations under this
Deposit Agreement except to account for such net proceeds and money and other
property.

     Upon the termination of this Deposit Agreement, the Company shall be
discharged from all obligations under this Deposit Agreement except for its
obligations to the Depositary, any Depositary's Agent and any Registrar under
Sections 5.07 and 5.08. In the event this Deposit Agreement is terminated, the
Company hereby agrees to use its reasonable efforts to list the underlying New
Preferred Stock on the NYSE or any other national securities exchange on which
the Common Stock is listed.

The Washington Water Power Company
1411 East Mission Avenue
Spokane, Washington 99202

Ladies and Gentlemen:

     We are acting as counsel to The Washington Water Power Company (the 
"Company") in connection with the proposed issuance by the Company of up to 
2,000,000 shares of its Preferred Stock, Convertible Series L (the "New 
Preferred Stock"), and a number of shares of Common Stock (the "New Common 
Stock") to be delivered upon conversion of the New Preferred Stock, and the 
related delivery of depositary receipts evidencing depositary shares each 
constituting a one-tenth interest in one share of the New Preferred Stock 
deposited with The Bank of New York, as depositary under a Deposit Agreement 
with the Company (the "Deposit Agreement"), all as contemplated by the 
registration statement on Form S-4 filed by the Company with the Securities 
and Exchange Commission on August 17, 1998 under the Securities Act of 1933, 
as amended (the "Act"), said registration statement, as it may be amended, 
being hereinafter called the "Registration Statement".

     We have examined originals or copies, certified or otherwise identified 
to our satisfaction, of (i) the Registration Statement, (ii) a Certificate of 
Existence/Authorization issued by the Secretary of State of the State of 
Washington, (iii) the Company's Restated Articles of Incorporation and (iv) a 
form of the Articles of Amendment containing the terms and provisions of the 
New Preferred Stock (the "Articles of Amendment").  We have also examined 
such other documents and satisfied ourselves as to such other matters as we 
have deemed necessary in order to render this opinion.  As to various facts 
material to the opinions expressed below, we have relied on certificates of 
public officials, certificates of officers or employees of the Company, 
representations contained in the documents and other oral or written 
assurances by officers or employees of the Company.

     Based upon the foregoing and subject to the qualifications hereinafter
expressed, we are of the opinion that when:


                                      
<PAGE>

The Washington Water Power Company

          (a)  the Registration Statement shall have become effective under the
     Act (and assuming that no stop order shall have been issued);

          (b)  the Articles of Amendment shall have been filed with the
     Secretary of State of the State of Washington in the form and manner
     required by law;

          (c)  The Deposit Agreement shall have been duly executed and delivered
     by the Company;

          (d)  the certificates for shares of the New Preferred Stock have been
     duly countersigned and registered by a transfer agent and registrar; and

          (e)  the New Preferred Stock shall have been issued and delivered by
     the Company as contemplated by, and in conformity with, the acts,
     proceedings and documents referred to above and the Company's Restated
     Articles of Incorporation, as amended by the Articles of Amendment;

the New Preferred Stock will have been legally issued and will be fully paid 
and non-assessable, and the Deposit Agreement will have been duly authorized, 
executed and delivered by the Company, and, thereafter, when the New 
Preferred Stock shall have been converted as contemplated in the Articles of 
Amendment and the Rights appurtenant to such shares of Common Stock shall 
have been issued in accordance with the terms of the Rights Agreement, dated 
as of February 6, 1990, as amended (the "Rights Agreement"), between the 
Company and First Chicago Trust Company of New York, the New Common Stock 
issued upon such conversion will have been legally issued and will be fully 
paid and non-assessable and the Rights appurtenant thereto will have been 
legally issued; and no further approval, authorization, consent or other 
order of, or filing with, any governmental agency of the States of 
Washington, California, Idaho, Montana and Oregon will be legally required 
for the issuance by the Company of the New Preferred Stock or the New Common 
Stock (including the appurtenant Rights) as contemplated in the Registration 
Statement or in order for the New Preferred Stock and the New Common Stock to 
be fully paid and non-assessable or in order for the Deposit Agreement to be 
a legal and binding obligation of the Company.

     The opinions expressed herein are limited to the laws of the States of 
Washington, California, Idaho, Montana and Oregon (excluding therefrom 
principles of conflicts of laws, state securities or blue sky laws and laws 
of political subdivisions of such States).  To the extent the such opinions 
relate to or are dependent upon matters governed by the Federal Power Act, as 
amended, the Public Utility Holding Company Act of 1935, as amended, or the 
Investment Company Act of 1940, as amended, we have assumed the legal 
conclusions set forth in the opinion of Thelen Reid & Priest LLP which is 
being filed as Exhibit 5(b) and 8 to the Registration Statement.

     We note that we are not aware of any court decisions applying the law of 
the State of Washington that addresses plans similar to the Rights Agreement, 
and that, as a consequence, it is difficult to predict how a court applying 
such law would rule with respect to the due authorization and valid issuance 
of the Rights.  We have concluded that a court applying the law of the State 
of Washington, when presented with novel questions concerning matters such as 
the authorization and issuance of the Rights, after giving effect to reported 
court decisions concerning the "business judgment rule" under Washington law, 
most likely would look to and apply the corporate law of the State of 
Delaware. Accordingly, the opinions relating to the Rights expressed in the 
immediately

preceding paragraph are based upon such conclusion.  We do not herein express 
any opinion as to the enforceability of the Rights or the Rights Agreement 
under the law of the State of Washington.

     This opinion is given as of the date hereof, without any obligation upon 
us to update this opinion or to advise the addressee hereof or any other 
party of any changes in circumstances or laws that may hereafter be brought 
to our attention or occur which may affect this opinion.

     We hereby consent to the filing of this opinion as Exhibit 5(a) to the 
Registration Statement and to the references to our firm under the heading 
"Legal Matters" in the Prospectus which forms a part of the Registration 
Statement.  In giving the foregoing consent, we do not admit that we are 
within the category of persons whose consent is required under Section 7 of 
the Act or the rules and regulations promulgated thereunder.  Except as 
expressly permitted hereby, this opinion may not be used, delivered, 
circulated, filed, quoted or otherwise referred to.

Ladies and Gentlemen:

     We are acting as counsel to The Washington Water Power Company (the
"Company") in connection with the proposed issuance by the Company of up to
2,000,000 shares of its Preferred Stock, Convertible Series L (the "New

related delivery of depositary receipts (the "Depositary Receipts") evidencing

Preferred Stock deposited with The Bank of New York, as depositary (the
"Depositary") under a Deposit Agreement with the Company (the "Deposit

     Based upon the foregoing and subject to the qualifications hereinafter

          (a)  the Registration Statement shall have become effective under the

                                       -2-

          (c)  the New Preferred Stock shall have been issued and delivered by
     the Company as contemplated by, and in conformity with, the Company's
     Restated Articles of Incorporation, as amended, and the other acts,
     proceedings and documents referred to in the opinion of Paine, Hamblen,
     Coffin, Brooke & Miller LLP which is being filed as Exhibit 5(a) to the
     Registration Statement; and

          (d)  the Depositary Receipts shall have been duly executed by the
     Depositary and delivered as contemplated in the Deposit Agreement;

the Depositary Receipts will be legal and binding instruments with respect to
the deposit of the New Preferred Stock under the Deposit Agreement.

          We further are of the opinion that no approval, authorization 
consent or other order of, or filing with, the Federal Energy Regulatory 
Commission under the Federal Power Act, as amended, or the Securities and 
Exchange Commission under the Public Utility Holding Company Act of 1935, as 
amended, or the Investment Company Act of 1940, as amended, is required for 
the legal issuance by the Company of the New Preferred Stock or the New 
Common Stock (including the Rights appurtenant thereto) or for the legal 
issuance of the Depositary Receipts, as contemplated in the Registration 
Statement, or in order for the New Preferred Stock or the New Common Stock to 
be fully paid and non-assessable or for the Depositary Receipts to be legal 
and binding obligations.

          We are further of the opinion that the information contained in the
Registration Statement under "Certain United States Federal Income Tax
Consequences" constitutes an accurate description, in general terms, of the
indicated federal income tax consequences to the holders of the Company's Common
Stock of the exchange offer contemplated in the Registration Statement.

     The opinions expressed herein are limited to the laws of the State of New
York and the federal law of the United States (excluding therefrom principles of
conflicts of laws, state securities or blue sky laws).  To the extent that such
opinions relate to or are dependent upon matters governed by the laws of other
States, we have assumed the legal conclusions set forth in the opinion of Paine,
Hamblen, Coffin, Brooke & Miller LLP, which is being filed as Exhibit 5(a) to
the Registration Statement.

     We hereby consent to the filing of this opinion as Exhibit 5(b) and 8 to
the Registration Statement and to the references to our firm in the Registration
Statement.  In giving the foregoing consent, we do not admit that we are within
the category of persons whose consent is required under Section 7 of the Act or

                 PLEASE READ THE ACCOMPANYING INSTRUCTIONS CAREFULLY

Ladies and Gentlemen:

     The undersigned hereby tenders to The Washington Water Power Company, a
Washington corporation (the "Company"), the above-described Common Shares
pursuant to the offer by the Company to exchange up to 20,000,000 Common Shares
for depositary shares each constituting a one-tenth interest in one share of the
Company's $12.40 Preferred Stock, Convertible Series L (each such depositary
share being herein called a "RECONS"), upon the terms and subject to the
conditions set forth in the Prospectus dated October __, 1998 (the
"Prospectus"), receipt of which is hereby acknowledged, and in this Letter of
Transmittal (which together constitute the "Exchange Offer").  Common Shares not
accepted for exchange because of proration will be returned.

     Subject to and effective upon acceptance for exchange of the Common Shares
tendered herewith, the undersigned hereby sells, assigns and transfers to or
upon the order of the Company all right, title and interest in and to all the
Common Shares that are being tendered hereby and appoints the Exchange Agent the
true and lawful agent and attorney-in-fact of the undersigned with respect to
such Common Shares, with full power of substitution (such power of attorney
being deemed to be an irrevocable power coupled with an interest), to (a)
deliver certificates for such Common Shares or transfer ownership of such Common
Shares on the account books maintained by DTC, together, in any such case, with
all accompanying evidences of transfer and authenticity, to the Exchange Agent
for the account of the Company, (b) present such Common Shares for transfer on
the books of the Company and (c) receive all benefits and otherwise exercise all
rights of beneficial ownership of such Common Shares, all in accordance with the
terms of the Exchange Offer.

     The undersigned hereby represents and warrants that the undersigned has
full power and authority to tender, exchange, assign and transfer the Common
Shares tendered hereby and to acquire RECONS issuable upon the exchange of such
tendered Common Shares and that, when the undersigned's Common Shares are
accepted for exchange, the Company will acquire good and unencumbered title to
such Common Shares, free and clear of all liens, restrictions, charges and
encumbrances and not subject to any adverse claim.  The undersigned will, upon
request, execute and deliver any additional document deemed by the Company to be
necessary or desirable to complete the exchange, assignment and transfer of
tendered Common Shares or transfer ownership of such Common Shares.

     All authority herein conferred or agreed to be conferred shall survive the
death, bankruptcy or incapacity of the undersigned and every obligation of the
undersigned hereunder shall be binding upon the heirs, legal representatives,
successors, assigns, executors and administrators of the undersigned.  Except as
stated in the Exchange Offer, this tender is irrevocable.  Any tender of Common
Shares hereunder may be withdrawn only in accordance with the procedures set
forth in the Prospectus under "The Exchange Offer--Withdrawal of Tendered Common
Shares."

     The undersigned understands that tenders of Common Shares pursuant to any
one of the procedures described in the Prospectus (see "The Exchange
Offer--Procedure for Tender") and in the instructions hereto will constitute an
agreement between the undersigned and the Company upon the terms and subject to
the conditions of the Exchange Offer, including the tendering holder's
representation and warranty that (i) such holder owns the Common Shares being
tendered within the meaning of Rule 14e-4 promulgated under the Securities
Exchange Act of 1934, as amended, and (ii) the tender of such Common Shares
complies with Rule 14e-4.

     The undersigned understands and agrees that (i) the Preferred Stock to be
delivered in exchange for Common Shares tendered by the undersigned and accepted
for exchange pursuant to the Exchange Offer will be deposited under the Deposit
Agreement (the "Deposit Agreement") dated as of October __, 1998 between the
Company and The Bank of New York, as Depositary, (ii) the RECONS will be subject
to the terms and conditions of the Deposit Agreement, and (iii) the RECONS will
be evidenced by receipts ("Depositary Receipts") issued pursuant to the Deposit
Agreement.

     The undersigned recognizes that, under certain circumstances and subject to
certain conditions to the Exchange Offer (any or all of which the Company may
waive) set forth in the Prospectus, the Company may not

                                       -3-
<PAGE>

be required to accept for exchange any of the Common Shares that the 
undersigned has tendered (including any Common Shares tendered after the 
Expiration Date).  Common Shares delivered to the Exchange Agent and not 
accepted for exchange will be returned to the undersigned as promptly as 
practicable following expiration or termination of the Exchange Offer at the 
address set forth on the cover page of this Letter of Transmittal unless 
otherwise indicated under "Special Delivery Instructions" below.

     Unless otherwise indicated under "Special Issue Instruction" below, 
please cause Depositary Receipts to be issued, and return any Common Shares 
not tendered or not accepted for exchange, in the name(s) of the undersigned 
(or, in the case of Common Shares tendered by book-entry transfer and 
Depositary Receipts to be issued into DTC, by credit to the account at DTC 
designated above).  Similarly, unless otherwise indicated under "Special 
Delivery Instruction," please mail any certificates for Common Shares not 
tendered or not accepted for exchange (and accompanying documents, as 
appropriate), and any Depositary Receipts issued pursuant to the Exchange 
Offer, to the undersigned at the address shown below the undersigned's 
signature(s).  If both "Special Issue Instructions" and "Special Delivery 
Instructions" are completed, please cause Depositary Receipts to be issued, 
and return any Common Shares not tendered or not accepted for exchange, in 
the name(s) of, and deliver any certificates for such Common Shares and such 
Depositary Receipts to, the person(s) so indicated. The undersigned 
recognizes that the Company has no obligation, pursuant to the "Special Issue 
Instructions," to transfer any Common Shares from the name of the registered 
holder(s) thereof if the Company does not accept for exchange any of the 
Common Shares so tendered.

                                     INSTRUCTIONS

            FORMING PART OF THE TERMS AND CONDITIONS OF THE EXCHANGE OFFER

     1.  GUARANTEE OF SIGNATURES.  Except as otherwise provided below, all
signatures on this Letter of Transmittal must be guaranteed by a firm that is a
participant in the Securities Transfer Agents Medallion Program, the New York
Stock Exchange Medallion Signature Program or the Stock Exchange Medallion
Program (each being an "Eligible Institution").  Signatures on this Letter of
Transmittal need not be guaranteed if (a) this Letter of Transmittal is signed
by the registered holder(s) of the Common Shares tendered herewith and such
holder(s) have not completed either of the boxes entitled "Special Issue
Instructions" or "Special Delivery Instructions" on this Letter of Transmittal
or (b) such Common Shares are tendered for the account of an Eligible
Institution.  See Instruction 5.

     2.  DELIVERY OF LETTER OF TRANSMITTAL AND COMMON SHARES; AGENT'S 
MESSAGE. This Letter of Transmittal is to be completed by holders of Common 
Shares either (i) if Common Shares are to be tendered herewith or (ii) unless 
an Agent's Message is utilized, if tenders are to be made pursuant to the 
procedure for tender by book-entry transfer set forth in the Prospectus under 
"The Exchange Offer--Procedure for Tender."  Certificates for Common Shares, 
or timely confirmation of a book-entry transfer of such Common Shares into 
the Exchange Agent's account at DTC, as well as this Letter of Transmittal 
(or a manually signed facsimile hereof), properly completed and duly 
executed, with any required signature guarantees, or an Agent's Message (in 
the case of a book-entry transfer of shares), and any other documents 
required by this Letter of Transmittal, must be received by the Exchange 
Agent at one of its addresses set forth in the front page hereof prior to the 
Expiration Date.  An "Agent's Message" is a message transmitted through 
electronic means by DTC to and received by the Exchange Agent and forming a 
part of a book-entry confirmation, which states that DTC has received an 
express acknowledgment from the participant tendering the Common Shares that 
such participant has received and agrees to be bound by the Letter of 
Transmittal.  Delivery of the Letter of Transmittal and any other required 
documents to DTC does not constitute delivery to the Exchange Agent.

     If a holder of Common Shares desires to participate in the Exchange 
Offer and time will not permit this Letter of Transmittal or Common Shares to 
reach the Exchange Agent before the Expiration Date or the procedure for 
book-entry transfer cannot be completed on a timely basis, a tender may be 
effected if the Exchange Agent has received at its office prior to the 
Expiration Date, from or through an Eligible Institution, a properly 
completed and duly executed Notice of Guaranteed Delivery substantially in 
the form provided by the Company, setting forth the name and address of the 
tendering holder, the name(s) in which the Common Shares are registered and, 
if the Common Shares are held in certificated form, the certificate numbers 
of the Common Shares to be tendered, and stating that the tender is being 
made thereby and guaranteeing that within three New York Stock Exchange, Inc. 
("NYSE") trading days after the date of execution of such Notice of 
Guaranteed Delivery by the Eligible Institution, the Common Shares in proper 
form for transfer or a confirmation of book-entry transfer of such Common 
Shares into the Exchange Agent's account at DTC, together with a properly 
completed and duly executed Letter of Transmittal (or manually signed 
facsimile thereof), or an Agent's Message in connection with a book-entry 
transfer, and any other required documents, will be delivered by such 
Eligible Institution.  Unless the Common Shares being tendered by the 
above-described method are deposited with the Exchange Agent within the time 
period set forth above or a confirmation of book-entry transfer of such 
Common Shares into the Exchange Agent's account at DTC is received 
(accompanied or preceded by a properly completed Letter of Transmittal and 
any other required documents), the Company may, at its option, reject the 
tender.

     THE METHOD OF DELIVERY OF COMMON SHARES AND ALL OTHER REQUIRED 
DOCUMENTS, INCLUDING DELIVERY THROUGH DTC, IS AT THE OPTION AND RISK OF THE 
TENDERING SHAREHOLDER AND ANY DELIVERY WILL BE DEEMED MADE ONLY WHEN ACTUALLY 
RECEIVED BY THE EXCHANGE AGENT.  IF CERTIFICATES FOR COMMON SHARES ARE SENT 
BY MAIL, REGISTERED MAIL WITH RETURN RECEIPT REQUESTED, PROPERLY INSURED, IS 
RECOMMENDED. IN ALL CASES, SUFFICIENT TIME SHOULD BE ALLOWED TO ENSURE TIMELY 
DELIVERY.

                                       -6-
<PAGE>

     No alternative, conditional or contingent tenders will be accepted, and 
no fractional shares of Common Shares will be accepted for exchange.  By 
executing this Letter of Transmittal (or a manually signed facsimile hereof), 
the tendering holder waives any right to receive any notice of the acceptance 
of the Common Shares attached hereto.

     3.  INADEQUATE SPACE.  If the space provided herein is inadequate, the 
certificate numbers and/or the number of Common Shares should be listed on a 
separate signed schedule attached hereto.

     4.  PARTIAL TENDERS.  (Not applicable to Book-Entry Shareholders).  If 
fewer than all Common Shares represented by any certificate delivered to the 
Exchange Agent are to be tendered, fill in the number of Common Shares which 
are to be tendered in the box entitled "Number of Shares Tendered."  In such 
case, a new certificate for the remainder of the Common Shares represented by 
the old certificate will be sent to the person(s) signing this Letter of 
Transmittal, unless otherwise provided in the appropriate box on this Letter 
of Transmittal, as promptly as practicable following the Expiration Date.  
All Common Shares represented by certificates delivered to the Exchange Agent 
will be deemed to have been tendered unless otherwise indicated.

     5.  SIGNATURES ON LETTER OF TRANSMITTAL; STOCK POWERS AND ENDORSEMENTS.  
If this Letter of Transmittal is signed by the registered holder(s) of the 
Common Shares tendered hereby, the signature(s) must correspond with the 
name(s) as written on the face of the certificates, reinvestment statement of 
account or on the security position listing of DTC without alteration, 
enlargement or any change whatsoever.

     If any of the Common Shares tendered hereby are held of record by two or 
more persons, all such persons must sign this Letter of Transmittal.

     If any of the Common Shares tendered hereby are registered in different 
names on different certificates, it will be necessary to complete, sign and 
submit as many separate Letters of Transmittal as there are different 
registrations of certificates.

     If this Letter of Transmittal is signed by the registered holder(s) of 
the Common Shares tendered hereby, no endorsements of certificates or 
separate stock powers are required unless Depositary Receipts issued in 
exchange therefor are to be issued, or Common Shares not tendered or not 
exchanged are to be returned, in the name of any person other than the 
registered holder(s).  Signatures on any such certificates or stock powers 
must be guaranteed by an Eligible Institution as set forth above "1.  
Guarantee of Signatures."

     If this Letter of Transmittal is signed by a person other than the 
registered holder(s) of the Common Shares tendered hereby, certificates must 
be endorsed or accompanied by appropriate stock powers, in either case, 
signed exactly as the name(s) of the registered holder(s) appear(s) on the 
certificates for such Common Shares.  Signature(s) on any such certificates 
or stock powers must be guaranteed by an Eligible Institution.

     If this Letter of Transmittal or any certificate or stock power is 
signed by a trustee, executor, administrator, guardian, attorney-in-fact, 
officer of a corporation or other person acting in a fiduciary or 
representative capacity, such person should so indicate when signing, and 
proper evidence satisfactory to the Company of the authority of such person 
so to act must be submitted.

     6.  SPECIAL ISSUE AND DELIVERY INSTRUCTIONS.  If Depositary Receipts are 
to be issued, or any Common Shares not tendered or not accepted for exchange 
are to be returned, in the name of a person other than the person(s) signing 
this Letter of Transmittal, or any Depositary Receipts issued, or 
certificates for Common Shares not tendered or not accepted for exchange, are 
to be mailed to someone other than the person(s) signing this Letter of 
Transmittal or to the person(s) signing this Letter of Transmittal at an 
address other than shown above, the appropriate boxes on this Letter of 
Transmittal should be completed. Common Shares not accepted for exchange

                                       -7-
<PAGE>

will be returned and Depositary Receipts will be issued to a Book-Entry 
Shareholder by crediting the account at DTC designated above.

     7.  PARTICIPANTS IN THE DIVIDEND REINVESTMENT AND STOCK PURCHASE PLAN OF
THE COMPANY.  If a shareholder desires to tender, pursuant to the Exchange
