                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. To improve financial flexibility
and retain a larger share of earnings in order to fund future growth, the Board
announced a plan to lower the annual dividend paid to you, from $1.24 to $.48
per Common Share. We also announced that we intend to change our corporate name
to Avista Corporation effective January 1, 1999.
 
    Recognizing that some of you may rely on current income from the dividend,
we have created an opportunity for you to exchange your Common Shares for a new
security called RECONS-SM- (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 $24.00 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 $24.00, 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 27. 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 WEDNESDAY, NOVEMBER 18, 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) 648-1443.
 
    All shareholders should 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. This symbol will change
to "AVA" effective January 1, 1999. WWP has a long history of innovation and
leadership. We trust you will find this Exchange Offer is consistent with that
legacy.
 
    [SIGNATURE]
 
NEITHER THE SECURITIES AND EXCHANGE COMMISSION NOR ANY STATE SECURITIES
COMMISSION HAS APPROVED OR DISAPPROVED THE PREFERRED STOCK OR RECONS TO BE
ISSUED IN THE EXCHANGE OFFER OR DETERMINED IF THIS PROSPECTUS IS ACCURATE OR
ADEQUATE. ANY REPRESENTATION TO THE CONTRARY IS A CRIMINAL OFFENSE.

                 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 have applied 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
$24.00. 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, if any, and a premium payable in cash or Common Shares.
    

Q17: How do I learn more about the Exchange Offer?
A17: This document contains a complete description of the terms of the Exchange
Offer and you are strongly encouraged to read the entire document. If you are an
individual or institutional Shareholder and after reading this document, have
further questions, please contact the Information Agent. If you are an
institutional shareholder, you may also contact the Dealer Manager, referred to
in the letter of the Chairman of the Board, President and Chief Executive
Officer at the beginning of this document.

This summary highlights selected information from this Prospectus and does 
not contain all the information that you should consider. To understand the 
Exchange Offer fully and for a more complete description of the legal terms 
of the Exchange Offer, you should read carefully this entire document and the 
documents to which we have referred you. See "Questions and Answers About the

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 provide electricity and natural gas in eastern Washington and northern 
Idaho and natural gas service in northeast and southwest Oregon and the South 
Lake Tahoe region of California. Washington Water Power also operates Avista 
Capital ("Avista"), which owns all the Company's non-regulated energy and 
non-energy 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 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.

Date"), the RECONS will be mandatorily converted into
(1) one Common Share per RECONS (subject to certain
antidilution adjustments), and (2) the right to
receive a cash amount equal to all accrued but unpaid
dividends thereon.

Optional Conversion

We will have the option at any time on or after              Does not apply.
December 15, 1998 and before November 1, 2001 to
convert all of the outstanding RECONS. On such an
optional conversion date, a holder will receive for
each RECONS (1) the "RECONS Optional Conversion
Price" plus (2) a cash amount equal to all accrued
and unpaid dividends to but excluding the conversion
date plus (3) the "RECONS Optional Conversion
Premium," if any.

<S>                                                              <C>

The RECONS Optional Conversion Price equals
the number of Common Shares equal to the
lesser of (i) the amount of $24.00 (which is
128% of the closing price of a Common Share
on the Consolidated Tape on October 20,
1998) divided by the Current Market Price
(as defined herein) 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 $24.00 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 on 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 optional
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 up to but
excluding the conversion date.

Voting Rights

Holders of RECONS will not have the right to vote with           Holders of Common Shares have one vote for 
the holders of Common Shares, but if we fail to pay              each share on all matters submitted generally for 
quarterly dividend payments for 18 months, then                  a vote of the shareholders of the Company, 
holders of RECONS will be entitled, voting together              except that they can vote cumulatively in the 
with the holders of other Preferred Stock of WWP, to             election of directors.
elect a majority of the Board of Directors of WWP. 
In that situation, each RECONS would receive one-tenth 
of the vote allotted to one share of Preferred Stock.

Trading and Listing

The RECONS will be newly issued.  There is currently                The Common Shares are listed and trade on the
no market for RECONS.  We  have applied to list the                 NYSE and the Pacific Exchange, in each case
RECONS on the NYSE subject to listing requirements,                 under the symbol "WWP."  Effective January 1,
including the requirement that the shares be broadly                1999, the Company will change its name to
distributed.  We anticipate that the RECONS will be                 Avista Corporation and the Common Shares will
listed and trade under the symbol "WWPPrL" until                   trade under the symbol "AVA" on the NYSE and
January 1, 1999 when the symbol will be changed to                  the Pacific Exchange.
"AVAPrL". If the conditions to listing on the NYSE 
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.

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:

The above tables are presented for illustration only. Total return is 
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 43.

    

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

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

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 plus the Optional
Conversion Premium, 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.

    

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 have applied to list the RECONS 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.

    

                                       12

<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, 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 on
the Mandatory Conversion Date or earlier, the total number of Common Shares
outstanding will be increased by the number of Common Shares issued 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 estimates for capital expenditures (as 
reported in the Company's Annual Report on Form 10-K for 1997) do not include 
expenditures that would be required to fund such strategies. Additional 
capital expenditures that would be required during the 1999-2000 period could 
range from $400 million to $600 million. Sources of funds would include, but 
are not necessarily limited to, cash flows from the reduction in the 
Company's common stock dividend that was announced on August 17, 1998, 
monetization of certain long-term contracts, an increase in the sale of the 
Company's accounts receivable, sales of certain assets, additional long-term 
debt, leasing or other equity securities. 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 
business is driven by the Company's significant base of knowledge and 
experience in the operation of physical

    

                                       14

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, which risks are described further
in the Company's reports filed with the SEC and incorporated by reference
herein. 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.

    

   

For a complete description of the Company's business and investment
considerations relevant to an investment in the Company, investors are
encouraged to carefully review the documents incorporated in this Prospectus by

The increased revenues over the periods presented are primarily the result of 
increased energy trading and marketing activities of Avista Energy. Resource 
costs for these same periods increased by nearly the same amount. Net income 
for the 12 months ended September 30, 1998 did not include the $47.3 million 
income tax recovery in June 1997, which was included in the other periods 
shown. Preferred dividends decreased over the periods presented due to 
redemptions, but have been offset by increased interest expense.

                               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 . 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 shall either (i) decline to accept for exchange and exchange any of 
the Common Shares tendered and terminate the Exchange Offer or (ii) 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.

                                       18
<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 extended. The 
term "Expiration Date" shall mean 12:00 Midnight, New York City time, on 
Wednesday, November 18, 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). Shares
validly tendered but not accepted for exchange will be promptly returned
following final determination of the proration factor.
    

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.

                                       19
<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 Plan, 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.

                                       20
<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) 

                                       21
<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 December 17, 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 . 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 DTC to be credited with the
withdrawn Common Shares. Withdrawals may not be rescinded and Common Shares
withdrawn will thereafter be deemed 

                                       22
<PAGE>


not validly tendered for purposes of the Exchange Offer. However, withdrawn 
Common 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 8 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

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

the commencement of a war, armed hostilities or other international or 
national calamity directly or indirectly involving the United States, (iv)

Shares, (vi) in the case of any of the foregoing existing at the time of the 
commencement of the Exchange Offer, a material acceleration or worsening 
thereof or (vii) any decline in either the Dow Jones Industrial Average 
(8,505.85 at the close of trading on October 20, 1998) or the Standard and 
Poor's 500 Index (1,063.93 at the close of trading on October 20, 1998) by an 
amount in excess of 15% measured from the close of trading on October 20, 
1998;

    

(d) any tender or exchange offer with respect to some or all of the Common
Shares (other than the Exchange Offer), or a merger, acquisition or other
business combination proposal for the Company, shall have been proposed,
announced or made by any person or entity;

(e) any change shall occur or be threatened in the business, condition
(financial or other), income, operations, Common Share ownership or prospects of
the Company and its subsidiaries, taken as a whole, which, in the sole judgment
of the Company, is or may be material to the Company; or

   
(f) (i) any person, entity or "group" (as that term is used in Section

than a person, entity or group which had publicly disclosed such ownership in 
a Schedule 13D or 13G (or an amendment thereto) on file with the SEC prior to 
October 21, 1998 (date of commencement of the Exchange Offer), (ii) any such 
person, entity or group which had publicly disclosed such ownership prior to 
such date shall have acquired, or proposed to acquire, beneficial ownership 
of additional Common Shares constituting more than 2% of the outstanding 
Common Shares (options for and other rights to acquire Common Shares which 
are so acquired or proposed to be acquired being deemed for this purpose to 
be immediately exercisable) or (iii) any new group shall have been formed 
which beneficially owns more than 5% of the outstanding Common Shares;
    

                                       24
<PAGE>

and, in the sole opinion of the Company, in any such case and regardless of the
circumstances (including any action or omission to act by the Company) giving
rise to such condition, such event makes it inadvisable to proceed with the
Exchange Offer or with such acceptance for exchange or such exchange.

The foregoing conditions are for the sole benefit of the Company and may be
asserted by the Company regardless of the circumstances (including any action or
inaction by the Company) giving rise to any such condition, and any such
condition may be waived by the Company, in whole or in part, at any time and
from time to time in its sole discretion, with respect to the Exchange Offer.
The Company's failure at any time to exercise any of the foregoing rights shall
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.

Commissions and Fees

Tendering shareholders will not be obligated to pay brokerage commissions,
solicitation fees, or, subject to Instruction 7 of the Letter of Transmittal,
stock transfer taxes on the acquisition of Common Shares by the Company in
connection with the Exchange Offer. The Company will pay reasonable and
customary compensation to, and all reasonable charges and expenses of, The Bank
of New York, as Exchange Agent, and Morrow & Co, Inc., as Information Agent, in
connection with the Exchange Offer and each may be indemnified against certain
liabilities and expenses in connection therewith. The Company will not pay any
commission or other remuneration to any broker, dealer, salesman or other person
for soliciting tenders of Common Shares in connection with the Exchange Offer,
except as discussed under "Dealer Manager." Officers and regular employees of
the Company and its affiliates may solicit tenders of Common Shares in
connection with the Exchange Offer by telecopier, telephone or in person. No
additional compensation will be paid to any such officers and employees who
engage in soliciting tenders.

Status of Common Shares Acquired Pursuant to the Exchange Offer

Any Common Shares acquired by the Company pursuant to the Exchange Offer will
return to the status of authorized but unissued shares. Subject to the receipt
of necessary regulatory approvals, such shares would be available for use by the
Company, without, in most cases, the need for further shareholder authorization,
for general or other corporate purposes, including conversion of RECONS, stock
splits or dividends, acquisitions, employee incentive, savings and compensation
plans, sales to a third party or parties, or issuance of rights or warrants to
purchase Common Shares. Except for use in employee benefit plans and conversion
of RECONS, the Company has no present plan to issue any authorized but unissued
Common Shares.

                              Description of RECONS


General

   
Each RECONS constitutes a one-tenth (1/10) interest in one share of a New
Preferred Stock deposited under the Deposit Agreement (the "Deposit Agreement"),
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 or, in certain events, cash 
may be distributed by the Depositary in lieu of any fractional interest in 
shares of New Preferred Stock. 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 the
New Preferred Stock into Common Shares at any time prior to the Mandatory
Conversion Date. Upon any such conversion, 

                                       27
<PAGE>

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 Depositary, as
registered holder of such shares of New Preferred Stock, will endeavor, insofar
as practicable, to vote with 

                                       28
<PAGE>

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.

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"). The
New Preferred Stock will constitute a new series of the Preferred 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.

                                       30

Dividend Rights

   
The New Preferred Stock will be a new series of the Preferred Stock which 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 trading date next
preceding the date of issuance of the New Preferred Stock, as reported on the
Consolidated Tape maintained by the Consolidated Tape Association, plus an
amount equal to accrued and unpaid dividends.
    

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 $0.18 (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 
    

                                       31
<PAGE>

   
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 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 on the Consolidated Tape
maintained by the Consolidated Tape Association, 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 $24.00 divided by the Current Market
Price on the second trading day immediately preceding (i) the day on which the
Company gives notice of optional conversion or (ii) in the event of an
Extraordinary Transaction, the effective date of such transaction 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 and
including 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 (i) the day on which the Company gives notice
of such optional conversion or (ii) in the event of an Extraordinary
Transaction, the effective date of such transaction.
    

   
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 in respect of any conversion on or after September 15, 2001. Dividends
will accrue on the Preferred Stock up to but excluding the conversion date.
    

                                    32

<PAGE>

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 mandatory conversion 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.

   
No fractional shares of Common Stock will be issued upon any conversion of 
the New Preferred Stock. Instead of any fractional interest in a share of 
Common Stock which would otherwise be deliverable upon the conversion of a 
share of New Preferred Stock, the Company will 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 day immediately preceding (i) the day on which the Company 
gives notice of an optional conversion, (ii) in the event of an Extraordinary 
Transaction, the effective date of such transaction or (iii) in the event of 
a mandatory conversion, the Mandatory Conversion Date.
    

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 

                                       33
<PAGE>

shall have been determined; and provided, further, that if the shares of the
series to be issued are to have a variable dividend 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.

                                       34
<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.

                                       36
<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 $24.00 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 

                                       37
<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 

                                       38
<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.

                                       39
<PAGE>

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.

                              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 20, 1998. No approval or consent of shareholders was
required.
    

   
     THIRD: The Restated Articles of Incorporation are hereby amended by the
addition of a paragraph (2) to be inserted at the end of subdivision (o) of
Article THIRD, which shall be and read as follows:
    

   
          (2) 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.
    

   
          (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, 
    

- --------
   
* Such amount will be equal to ten (10) times the average of the high and low
sales prices per share of the Common Stock on the trading date next preceding
the date of issuance of the shares of the twelfth series, as reported on the
Consolidated Tape maintained by the Consolidated Tape Association.
    

                                      A-1
<PAGE>

   
     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 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 
    

                                      A-2
<PAGE>

   
     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 the shares of said twelfth series
     been mandatorily converted 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 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 
    
                                      A-3
<PAGE>

   
     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 the shares of said
     twelfth series been mandatorily converted 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 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 the
     shares of said twelfth series been mandatorily converted 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) hereafter 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
    
                                      A-4
<PAGE>

   
     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:
    

   
          (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 (i) the day on which the 
     Company gives notice of an optional conversion, (ii) in the event of an 
     Extraordinary Transaction, the effective date of such transaction or (iii) 
     in the event of a mandatory conversion, the Mandatory Conversion 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 to remain closed or are closed because of a banking
         moratorium or otherwise;
    

   
                  (B) the term "Closing Price" on any day shall mean the
         reported last sale price on such day, or, in case no such sale takes
         place on such day, the average of the reported last bid and asked
         prices on such day, in either case as reported on the Consolidated Tape
         maintained by the Consolidated Tape Association, or, if the Common
         Stock is not listed or admitted to trading on any securities exchange
         which participates in the Consolidated Tape Association, 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);
    

   
                  (C) the term "Extraordinary Transaction" shall mean a merger
         or consolidation of the Corporation, a share exchange, division or
         conversion of the Corporation's capital stock or an amendment of the

                       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 20, 1998. No approval or consent of shareholders was
required.
    
     THIRD: The Restated Articles of Incorporation are hereby amended by the
addition of a paragraph (2) to be inserted at the end of subdivision (o) of
Article THIRD, which shall be and read as follows:

          (2) 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.

- -----------
    * Such amount will be equal to ten (10) times the average of the high
and low sales prices per share of the Common Stock on the trading date
next preceding the date of issuance of the shares of the twelfth series, as 
reported on the Consolidated Tape maintained by the Consolidated Tape 
Association.


<PAGE>




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

         (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

                                       -2-


<PAGE>



effective as of the close of business on the record date for determination of
shareholders entitled to 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 the shares of said twelfth series been
mandatorily converted 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

                                       -3-


<PAGE>



the number of shares of Common Stock which the aggregate offering price of the
total number of 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 the shares of said twelfth series been
mandatorily converted 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

                                       -4-


<PAGE>



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 the amount of cash such
holder would have received had the shares of said twelfth series been
mandatorily converted 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)
hereafter 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 (i) the day on which the Company gives 
notice of an optional conversion, (ii) in the event of an Extraordinary 
Transaction, the effective date of such transaction or (iii) in the event of 
a mandatory conversion, the Mandatory Conversion 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 to
remain closed or are closed because of a banking moratorium or otherwise;

     (B) the term "Closing Price" on any day shall mean the reported last sale
price on such day, or, in case no such sale takes place on such day, the average
of the reported last bid and asked prices on such day, in either case as
reported on the Consolidated Tape maintained by the Consolidated Tape
Association, or, if the Common Stock is not listed or admitted to trading on any
securities exchange which participates in the Consolidated Tape Association, 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);

     (C) the term "Extraordinary Transaction" shall mean a merger or
consolidation of the Corporation, a share exchange, division or conversion of
the Corporation's capital stock or an amendment of the Restated Articles of
Incorporation of the Corporation that results in the conversion

                                       -6-


<PAGE>



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 
each share of said twelfth series converted at the option of the Company, an 
amount, in cash, initially equal to $20.90, declining by $.02111 for each day 
following December 15, 1998 to and including the optional 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; provided, however, that in 
lieu of delivering such amount in cash, 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 Date 
immediately preceding (1) the date on which the Company gives notice of such 
conversion or (2) in the event of an Extraordinary Transaction, the effective 
date of such transaction;
    
     (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 $24.00
divided by the Current Market Price as of the second Trading Date immediately
preceding (a) the date on which the Company gives notice of such conversion or
(b) in the event of an Extraordinary Transaction, the effective date of such
transaction and (2) the number of shares of Common Stock determined by reference

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 Corporation by mailing a
copy of such notice not less than fifteen (15) days nor more than sixty (60)
days prior to the conversion date. Each such notice shall state (1) the
conversion date, (2) the total number of shares of said twelfth series to be
converted (being the total number of shares 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 dividends on the shares to be converted will cease to accrue
on such conversion date. Notwithstanding the foregoing, the failure so to mail
any such notice of mandatory conversion or any defect therein or in the mailing
thereof shall not prevent the occurrence of such conversion or impair the
validity thereof.

     (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

                                       -7-


<PAGE>



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

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
provided;

     (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.

     (viii) The Corporation shall pay any and all documentary, stamp or 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

                         [REVERSE OF DEPOSITARY RECEIPT]

     1. The Deposit Agreement. Depositary Receipts (the "Depositary Receipts"),
of which this Depositary Receipt is one, are made available upon the terms and
conditions set forth in the Deposit Agreement, dated as of _______, 1998 (the
"Deposit Agreement"), among the Company, the Depositary and all holders from
time to time of Depositary Receipts issued thereunder, each of whom by accepting
a Depositary Receipt agrees to be bound by all the terms and conditions thereof.
The Deposit Agreement (copies of which are on file at the Corporate Office and
at the office of any Depositary's Agent) sets forth the rights of holders of
Depositary Receipts and the rights and duties of the Depositary.

     The statements made on the face and reverse of this Depositary Receipt are
summaries of certain provisions of the Deposit Agreement and are qualified by
and subject to the detailed provisions thereof, to which reference is hereby
made. In the event of any conflict between the provisions of this Depositary
Receipt and the provisions of the Deposit Agreement, the provisions of the
Deposit Agreement will govern. Unless otherwise expressly herein provided, all
defined terms used herein shall have the meanings ascribed thereto in the
Deposit Agreement.

     2. 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 such conversion.

     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 as provided in paragraph 13 below of the Depositary
Receipts.

     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 each Depositary Receipt evidencing Depositary
Shares (properly endorsed or assigned for transfer, if the Depositary shall so
require), each such Depositary Share shall be exchanged for shares of Common
Stock at a rate equal to one-tenth of the number of shares of Common Stock into
which each share of New Preferred Stock shall have been converted; provided,
however, that no fractional shares of Common Stock shall be distributed.

     3. Surrender of Depositary Receipts and Withdrawal of New Preferred Stock
or Common Stock. Upon surrender of this Depositary Receipt to the Depositary at
the Corporate Office, or at such other office as the Depositary may designate,
and subject to the provisions of the Deposit Agreement, the holder hereof is
entitled to withdraw, and to obtain delivery, to or

upon the order of such holder, of any or all of the New Preferred Stock (but
only whole shares) and all money and other property, if any, at the time
represented by the Depositary Shares evidenced by this Depositary Receipt, but
holders of any such shares of New Preferred Stock will not thereafter be
entitled to deposit such shares of New Preferred Stock thereunder 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 and such money
and other property, if any, to be withdrawn, deliver, to or upon the order of
such holder, a new Depositary Receipt or Depositary Receipts evidencing such
excess number of Depositary Shares.

     4. Transfers, Split-ups, Combinations. Subject to paragraphs 5, 6 and 7
below, this Depositary Receipt is transferable on the books of the Depositary
upon surrender of this Depositary Receipt to the Depositary, properly endorsed
or accompanied by a properly executed instrument of transfer or endorsement, and
upon such transfer the Depositary shall sign and deliver a Depositary Receipt to
or upon the order of the person entitled thereto, all as provided in and subject
to the Deposit Agreement. This Depositary Receipt may be split into other
Depositary Receipts or combined with other Depositary Receipts into one
Depositary Receipt 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 a fractional Depositary Share.

     5. Conditions to Signing and Delivery, Transfer, etc., of Depositary
Receipts. Prior to the execution and delivery, transfer, split-up, combination,
surrender or exchange of this 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 New Preferred Stock being withdrawn or with
respect to 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 Deposit Agreement. Any
holder of this Depositary Receipt may be required to file such proof of
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 this
Depositary Receipt, the transfer or exchange of this Depositary Receipt, the
withdrawal of the New Preferred Stock or the Common Stock, as applicable,
represented by the Depositary Shares evidenced by this 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.

     6. Suspension of Delivery, Transfer, etc. The transfer, split-up,
combination, surrender or exchange of this Depositary Receipt may be suspended
(i) during any period when

                                        4


<PAGE>



the register of shareholders of the Company is closed, (ii) if any such 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 the Deposit Agreement, or (iii) with the approval of the
Company, for any other reason. 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.

     7. 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 this Depositary Receipt, the Depositary Shares evidenced by this
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 of the Deposit Agreement, such tax (including transfer, issuance or
acquisition taxes, if any) or governmental charge shall be payable by the holder
hereof. Until such payment is made, transfer of this Depositary Receipt or any
withdrawal of the New Preferred Stock represented by the Depositary Shares
evidenced by this 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 this Depositary Receipt remaining liable for any deficiency.

     8. Amendment. The form of the Depositary Receipts 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 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 Deposit Agreement), 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. The holder of this
Depositary Receipt at the time any such amendment becomes effective shall be
deemed, by continuing to hold this Depositary Receipt, to consent and agree to
such amendment and to be bound by the Deposit Agreement as amended thereby. In
no event shall any amendment impair the right, subject to the provisions of
paragraphs 2, 3, 6 and 7 hereof and of Sections 2.03, 2.06, 2.07 and Article III
of the Deposit Agreement, of the owner of the Depositary Shares evidenced by
this Depositary Receipt to surrender this Depositary Receipt with instructions
to the Depositary to deliver to the holder the New Preferred Stock or Common
Stock, as applicable, and all money and other property, if any, represented
thereby, except in order to comply with mandatory provisions of applicable law.

     9. Fees, Charges and Expenses. The Company will pay all fees, charges and
expenses of the Depositary, except for taxes (including transfer taxes, if any)
and other governmental charges and such charges as are expressly provided in the
Deposit Agreement to be at the expense of persons depositing New Preferred
Stock, holders of Depositary Receipts or other persons.

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

     11. Cash Dividends and 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) will, subject to the provisions of the Deposit Agreement, make such
distribution to record holders of Depositary Receipts 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 the event
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 by 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 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.

     12. Subscription Rights, Preferences or Privileges. If the Company shall at
any time offer or cause to be offered to the persons in whose name 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, subject to the provisions of the Deposit
Agreement, 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.

     13. Notice of Dividends, Fixing of 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 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

                                        6


<PAGE>



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.

     14. 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 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 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 determined as provided in paragraph
13 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.

     15. Reports, Inspection of Transfer Books. 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 holders of New Preferred
Stock and made generally available to the holders of New Preferred Stock by the
Company. The Depositary shall keep books at the Corporate Office for the
registration and transfer of Depositary Receipts, which books at all reasonable
times during normal business hours will be opened for inspection by the record
holders of the Depositary Receipts as and to the extent provided by applicable
law.

     16. Liability of the Depositary, the Depositary's Agent and 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 any
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
other circumstances beyond the control of the relevant party, the Depositary,
any Depositary's Agent or the Company shall be

                                        7


<PAGE>



prevented or forbidden from doing or performing any act or thing that the terms
of the 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 the
Deposit Agreement provide shall or may be done or performed, or by reasons of
any exercise of, or failure to exercise, any discretion provided for in the
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.

     17. 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 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.

     18. Termination of Deposit Agreement. The Deposit Agreement may be
terminated by the Company or the Depositary only after (i) all outstanding New
Preferred Stock shall have been converted as contemplated in Section 2.03 of the
Deposit Agreement 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 of the
Deposit Agreement, as applicable. The Company and the Depositary will undertake
to terminate the Deposit Agreement as soon as reasonable practicable after any
such conversion or distribution. Upon the termination of the Deposit Agreement,
the Company shall be discharged from all obligations thereunder except for its
obligations to the Depositary, any Depositary's Agent and any Registrar under
Sections 5.07 and 5.08 of the Deposit Agreement.

     If any Depositary Receipts remain outstanding after the date of
termination, the Depositary thereafter shall discontinue all functions and be
discharged from all obligations as provided in the Deposit Agreement, except as
specifically provided therein.
