                          FORWARD-LOOKING STATEMENTS

   This prospectus includes "forward-looking statements" within the meaning of
Section 27A of the Securities Act and Section 21E of the Securities Exchange
Act of 1934, or the "Exchange Act." All statements other than statements of
historical fact included or incorporated by reference herein, for example,
regarding the prospects for the electric industry or our prospects, plans,
financial position and business strategy, may constitute forward-looking
statements. The Private Securities Litigation Reform Act of 1995 has
established that these statements qualify for safe harbors from liability.
Forward-looking statements may include words like we "believe," "anticipate,"
"expect," "plan," "will," "may," "could," "estimate," "intend" or words of
similar meaning. Forward-looking statements describe our future plans,
objectives, expectations or goals. Such statements address future events and
conditions concerning:

   .   capital expenditures,

   .   earnings,

   .   liquidity and capital resources,

   .   litigation,

   .   possible corporate restructurings (including the separation of our
       regulated and unregulated businesses), mergers, acquisitions and
       dispositions (including our intended sale of our ownership interests in
       ONEOK),

   .   compliance with debt and other restrictive covenants,

   .   interest and dividends,

   .   Protection One, Inc.'s financial condition and its impact on our
       consolidated results,

   .   impairment charges that have been expensed during the first quarter of
       2002 or that may be expensed hereafter,

   .   environmental matters,

   .   nuclear operations,

   .   ability to enter new markets successfully and capitalize on growth
       opportunities in non-regulated businesses,

   .   events in foreign markets in which investments have been made and

   .   the overall economy of our service area.

   What happens in each case could vary materially from what we expect because
of such things as:

   .   electric utility deregulation,

   .   ongoing municipal, state and federal activities, such as the Wichita
       municipalization effort,

   .   future economic conditions,

   .   changes in accounting requirements and other accounting matters,

   .   changing weather,

   .   rate and other regulatory matters, including the impact of (i) the
       Kansas Corporation Commission's order to reduce our rates issued on July
       25, 2001, (ii) the Kansas Corporation Commission's order issued July 20,
       2001 and related proceedings with respect to the proposed separation of
       our electric utility businesses from Westar Industries, Inc. and (iii)
       the Kansas Corporation Commission's recent comments and orders relating
       to our refinancing activities,

                                      ii



   .   the impact on our service territory of the September 11, 2001 terrorist
       attacks,

   .   the impact of Enron Corporation's bankruptcy on the market for trading
       wholesale electricity,

   .   our liquidity, financial position and results of operations,

   .   political, legislative and regulatory developments,

   .   amendments or revisions to our current business and financial plans,

   .   the outcome of litigation related to the agreement concerning the
       acquisition of our electric operations by Public Service Company of New
       Mexico, which agreement has been terminated,

   .   regulatory, legislative and judicial actions,

   .   regulated and competitive markets and

   .   other circumstances affecting anticipated operations, sales and costs.

   These lists do not purport to be all-inclusive because it is not possible to
identify or predict all possible factors.

                              of payment to all other bonds currently
                              outstanding or hereafter issued under the
                              mortgage. The mortgage under which the
                              outstanding bonds were and the exchange bonds
                              will be issued prohibits us from incurring other
                              debt senior or equal to the bonds (unless certain
                              tests are met). The outstanding bonds were and
                              the exchange bonds will be subordinate to the
                              debt of our subsidiaries with respect to the

                              after giving effect to the issuance of the
                              outstanding bonds and notes, we would have had
                              total indebtedness on our consolidated balance
                              sheet of approximately $3.38 billion and $220
                              million of our mandatorily redeemable preferred
                              securities. Approximately $1.12 billion was
                              senior with respect to the assets of our
                              subsidiaries because our subsidiaries are the
                              obligors under such indebtedness. Our total
                              indebtedness includes approximately $298 million
                              of outstanding borrowings under our $400 million
                              revolving credit facility.

                              as described under "Description of

                              will have the right, as a holder of bonds, to
                              require us to repurchase all or part of your
                              bonds at a repurchase price equal to 101% of the

                              interest, if any, to the date of repurchase.

Risk Factors................  You should consider carefully all of the
                              information set forth in this prospectus and, in

                              will be our senior unsecured obligations, equal
                              in right of payment to all of our existing and
                              future unsecured senior indebtedness and other
                              obligations that are not, by their terms,

                              exchange notes.

                              The outstanding notes were and the exchange notes
                              will be effectively junior to all of our secured
                              indebtedness, including the exchange bonds
                              offered hereby and other obligations to the
                              extent of the value of the assets securing such
                              indebtedness and other obligations. The
                              outstanding notes were and the exchange notes
                              will be subordinate to the indebtedness of our
                              subsidiaries to the extent of their assets. As of
                              March 31, 2002, after giving effect to the
                              issuance of the outstanding bonds and notes, we
                              would have had total indebtedness on our
                              consolidated balance sheet of approximately $3.38
                              billion and $ million of our mandatorily
                              redeemable preferred securities. Approximately
                              $1.12 billion was senior with respect to the
                              assets of our subsidiaries because our
                              subsidiaries are the obligors under such
                              indebtedness and approximately $220 million would
                              have been senior indebtedness representing our
                              secured obligations. Our total indebtedness
                              includes approximately $298 million of
                              outstanding borrowings under our $400 million
                              revolving credit facility.

Optional Redemption.........  We may redeem all or a part of the notes at any
                              time and from time to time by paying a

                              the notes at 109.75% of their principal amount,

                              notes, we and our Restricted Subsidiaries will
                              not be required to comply with particular
                              covenants contained in the indenture. For more
                              detailed information on the covenants contained
                              in the securities resolution governing the notes,
                              see "Description of Notes."

Risk Factors................  You should consider carefully all of the
                              information set forth in this prospectus and, in
                              particular, you should evaluate the specific
                              factors set forth under "Risk Factors" herein and
                              in our 2001 Form 10-K before deciding whether to
                              invest in the exchange notes.

                                 RISK FACTORS

   In addition to the information contained elsewhere in this prospectus and in
the documents incorporated by reference herein (which includes certain of the
risk factors set forth in our Form 10-K for the year ended December 31, 2001),
the following risk factors should be carefully considered by each prospective
investor in deciding to exchange your outstanding securities for exchange
securities.

Risks Relating to the Exchange Securities

Our substantial indebtedness could impair our financial condition and our
ability to fulfill our obligations under our existing indebtedness as well as
under the securities.

   We have a significant amount of debt outstanding. The following chart shows
important credit statistics giving effect to the sale of the outstanding bonds
and outstanding notes and our use of the proceeds thereof to retire debt. The
chart also gives effect to the first quarter 2002 goodwill and customer account
impairment charges as of March 31, 2002:

                                                          March 31, 2002
                                                          --------------
                                                          (in thousands)
       Total debt........................................   $3,378,188
       Shareholders' equity and mandatorily redeemable
         preferred securities............................   $1,408,119
       Total debt as a percentage of total capitalization      70.6%

   Our substantial indebtedness could, for example:

   .   make it more difficult for us to satisfy our obligations with respect to
       the securities;

   .   reduce the amount of money available to finance our operations, capital
       expenditures and other activities;

   .   increase our vulnerability to economic downturns and industry conditions;

   .   limit our flexibility in responding to changing business and economic
       conditions, including increased competition and demand for new products
       and services;

   .   limit our ability to borrow additional funds; and

   .   impact our ability to pay dividends.

   We may incur substantial additional debt in the future, and we may do so in
order to finance future acquisitions and investments. The terms of the mortgage
and/or the indenture governing the bonds and the notes, respectively, will
permit us and our subsidiaries to do so, subject to certain limitations with
respect to our Restricted Subsidiaries, which conduct or hold our utility
businesses. The addition of further debt to our current debt levels could
intensify the leverage-related risks that we now face. The Note indenture also
permits us to incur additional debt senior to the notes including the first
mortgage bonds issued under the mortgage.

The securities are effectively subordinated to all debt and other liabilities
of our subsidiaries with respect to the assets of our subsidiaries.

   Significant portions of our operations are conducted through our
subsidiaries. Due to structural subordination, the securities will be
effectively subordinated to all existing and future indebtedness and other
liabilities and commitments of our subsidiaries with respect to the assets of
our subsidiaries. The mortgage and the indenture governing the bonds and the
notes, respectively, do not contain any covenants which restrict the ability of
our Unrestricted Subsidiaries, which conduct or hold our non-utility
businesses, to incur additional indebtedness. As of March 31, 2002, our
subsidiaries had approximately $1.12 billion of indebtedness outstanding, of
which $433 million is the debt of our Unrestricted Subsidiaries, not subject to
the covenants described under "Description of Notes."

                                      8



The agreements governing our indebtedness contain various covenants that limit
our management's discretion in the operation of our businesses and also require
us to meet certain financial maintenance tests. Failure to comply with any of
these tests could have a material adverse effect on us.

   The agreements governing our indebtedness contain various covenants,
including those that restrict our ability to:

   .   incur additional debt;

   .   pay dividends on, redeem or repurchase our capital stock;

   .   create liens; and

   .   consolidate, merge or sell all or substantially all of our assets.

   Any failure to comply with the restrictions of any of our existing or new
credit facilities or any agreement governing our indebtedness, including the
mortgage and the indenture governing the bonds and the notes, respectively, may
result in a default under such facilities and agreements. Such default may
allow the creditors to accelerate the related debt, which acceleration may
trigger cross-acceleration or cross-default provisions in other debt. For more
information, see "Description of Bonds" and "Description of Notes."

We may be unable to repurchase the bonds or the notes if we experience a change
of control.

   Following a change of control, we would be required to offer to purchase the
bonds and notes at a price equal to 101% of their principal amount, plus
accrued interest to the purchase date. We cannot assure you that we will have
sufficient funds available to make the required purchases of the bonds and/or
notes in that event.

   Any future debt that we incur may also contain restrictions on repurchases
in the event of a change of control or similar event. These purchase
requirements may delay or make it harder for a third party to obtain control of
our company.

   The change of control provisions may not protect you in a transaction in
which we incur a large amount of debt, including a reorganization,
restructuring, merger or other similar transaction, if the transaction does not
involve any shift in voting power or beneficial ownership or does not involve a
shift large enough to trigger a change of control as defined in the indentures
governing the bonds or notes, respectively.

   The change of control provisions do not apply to the proposed merger with
PNM or to any merger of a Restricted Subsidiary and us, or to the acquisition
of any additional shares of our common stock by Westar Industries.

An active or liquid trading market for the exchange securities may not develop.

   Prior to these offerings, there has been no public market for the exchange
securities. We intend to apply to have the exchange securities designated as
eligible for trading in the PORTAL Market. The initial purchasers of the
outstanding securities have informed us that they intend to make a market in
the exchange securities. However, they are not obligated to do so, and may
discontinue any such market-making with respect to the exchange bonds, the
exchange notes or both, at any time without notice. There can be no assurance
that an active trading market for the exchange securities will develop, or, if
one does develop, that it will be sustained.

   Historically, the market for non-investment grade debt has been highly
volatile in terms of price. It is possible that the market for the exchange
securities, as well as for the publicly tradeable exchange securities for which
they may be exchanged, will also be volatile. This volatility may affect your
ability to resell your outstanding bonds, outstanding notes or the exchange
bonds or exchange notes, as well as the timing of any such resale or exchange.

                                      9



Failure to exchange your outstanding securities will leave them subject to
transfer restrictions.

   If you do not exchange your outstanding securities for exchange securities,
you will continue to be subject to the restrictions on transfer of your
outstanding securities set forth in their legend, because the outstanding
securities were issued pursuant to an exemption from, or in a transaction not
subject to, the registration requirements of the Securities Act. In general,
outstanding securities may not be offered or sold unless registered under the
Securities Act, except pursuant to an exemption from, or in a transaction not
subject to, the Securities Act and applicable state securities laws. We
currently do not anticipate registering the outstanding securities under the
Securities Act. As outstanding securities are tendered and accepted in the
exchange offers, the aggregate principal amount of outstanding securities will
decrease, which decrease will decrease their liquidity.

Risks Relating to the Exchange Notes

Holders of our secured debt would be paid first to the extent of their security
interest if we were to become insolvent.

   The notes are not secured by any of our assets or any of the assets of our
subsidiaries. The indenture governing the notes permits us to incur additional
debt, including bonds, purchase money debt and other secured debt. If we were
to become insolvent, holders of any current and future secured debt would be
paid first to the extent of their security interest. Our bonds are secured by a
first lien on substantially all of our assets (excluding cash and accounts
receivable, securities not pledged under the mortgage, electric energy, gas,
water, materials and supplies held for consumption in operation or held in
advance of use for fixed capital purposes and merchandise, appliances and
supplies held for resale or lease to customers). Accordingly, investors in the
notes may not be fully repaid if we become insolvent.

   As of March 31, 2002, we had secured debt on our consolidated balance sheet
of approximately $1.4 billion giving effect to the issuance of the outstanding
notes and bonds. In addition, we may incur additional secured debt in the
future, including under our revolving credit facility. See "Description of
Bonds" and "Description of Notes."

Other Risks

Accountants

   The indictment of Arthur Andersen LLP may adversely affect Arthur Andersen
LLP's ability to satisfy any claims arising from the provision of auditing
services to us, including claims that may arise out of Arthur Andersen LLP's
audit of our financial statements incorporated by reference in this prospectus,
and may impede our access to the capital markets after completion of this
offering. Arthur Andersen LLP, which audited our financial statements
incorporated by reference in this prospectus for each of the years in the
three-year period ended December 31, 2001 has informed us that on March 14,
2002 an indictment was unsealed charging it with federal obstruction of justice
arising from the government's investigation of Enron Corp. Arthur Andersen LLP
has indicated that it intends to contest the indictment vigorously. Should we
seek to access the public capital markets after we complete this offering, SEC
rules will require us to include or incorporate by reference in any prospectus
three years of audited financial statements. The SEC's current rules would
require us to present audited financial statements for one or more fiscal years
audited Arthur Andersen LLP. If the SEC ceases accepting financial statements
audited by Arthur Andersen LLP, we could be unable to access the public capital
markets unless Deloitte and Touche LLP, our current independent accounting
firm, or another independent accounting firm, is able to audit the financial
statements originally audited by Arthur Andersen LLP. Any delay or inability to
access the public capital markets caused by these circumstances could have a
material adverse effect on our business, profitability and growth prospects.

                                      10



                                USE OF PROCEEDS

   We will not receive any cash proceeds from the issuance of the exchange
securities offered by this prospectus. In consideration for issuing the
exchange bonds or exchange notes as contemplated by this prospectus, we will
receive a like principal amount of outstanding bonds or outstanding notes, as
the case may be. The terms of the exchange securities will be identical in all
material respects to the terms of the outstanding securities for which they are
exchanged, except that the transfer restrictions and registration rights
applicable to the outstanding securities will not be applicable to the exchange
securities. The outstanding securities tendered in exchange for the exchange
securities will be retired and canceled. Accordingly, the issuance of the
exchange securities will not result in any increase in our indebtedness.

                                      11



                              THE EXCHANGE OFFERS

Purpose and Effect of the Exchange Offers

   Exchange Offer Registration Statements.  We issued the outstanding
securities on May 10, 2002. The initial purchasers have advised us that they
subsequently resold the outstanding securities to "qualified institutional
buyers" in reliance on Rule 144A under the Securities Act and to certain
persons in offshore transactions in reliance on Regulation S under the
Securities Act. As a condition to the offering of the outstanding securities,
we entered into registration rights agreements dated May 10, 2002, pursuant to
which we agreed, for the benefit of all holders of the outstanding securities,
at our own expense, to do the following:

      (1) to file the registration statement of which this prospectus is a part
   with the Commission on or prior to 180 days after the issue date of the
   outstanding securities,

      (2) to use our best efforts to cause the registration statement to be
   declared effective under the Securities Act within 270 days after the issue
   date of the outstanding securities, and

      (3) to use our best efforts to keep the registration statement effective
   during the one-year period following the consummation of the exchange offers.

   Further, we agreed to keep the exchange offers open for acceptance for not
less than 20 nor more than 35 business days (or longer if required by
applicable law). For each outstanding security validly tendered pursuant to the
exchange offers and not withdrawn, the holder of the outstanding security will
receive an exchange security having a principal amount equal to that of the
tendered outstanding security. Interest on each exchange security will accrue
from the last date on which interest was paid on the tendered outstanding
security in exchange therefor or, if no interest was paid on such outstanding
security, from the issue date.

   The following is a summary of the registration rights agreements relating to
the outstanding securities. It does not purport to be complete and it does not
contain all of the information you might find useful. For further information
you should read the registration rights agreement, a copy of which has been
filed as an exhibit to the registration statement. The exchange offers are
intended to satisfy certain of our obligations under the registration rights
agreement.

   Transferability.  We issued the outstanding securities on May 10, 2002 in a
transaction exempt from the registration requirements of the Securities Act and
applicable state securities laws. Accordingly, the outstanding securities may
not be offered or sold in the United States unless registered or pursuant to an
applicable exemption under the Securities Act and applicable state securities
laws. Based on no-action letters issued by the staff of the Commission with
respect to similar transactions, we believe that the exchange securities issued
pursuant to the exchange offers in exchange for outstanding securities may be
offered for resale, resold and otherwise transferred by holders of securities
who are not our affiliates without further compliance with the registration and
prospectus delivery requirements of the Securities Act, provided that:

      (1) any exchange securities to be received by the holder were acquired in
   the ordinary course of the holder's business;

      (2) at the time of the commencement of the exchange offers the holder has
   no arrangement or understanding with any person to participate in the
   distribution (within the meaning of the Securities Act) of the exchange
   securities; and

      (3) the holder is not an "affiliate" of the Company, as defined in Rule
   405 under the Securities Act.

   However, we have not sought a no-action letter with respect to the exchange
offers and we cannot assure you that the staff of the Commission would make a
similar determination with respect to the exchange offers. Any holder who
tenders his outstanding securities in the exchange offers with any intention of
participating in a distribution of exchange securities (1) cannot rely on the
interpretation by the staff of the Commission, (2) will

                                      12



not be able to validly tender outstanding securities in the exchange offers and
(3) must comply with the registration and prospectus delivery requirements of
the Securities Act in connection with any secondary resale transactions.

   In addition, each broker-dealer that receives exchange securities for its
own account pursuant to the exchange offers must acknowledge that it will
deliver a prospectus in connection with any resale of such exchange securities.
The letter of transmittal accompanying this prospectus states that by so
acknowledging and by delivering a prospectus, a broker-dealer will not be
deemed to admit that it is an "under-writer" within the meaning of Section
2(11) of the Securities Act. This prospectus, as it may be amended or
supplemented from time to time, may be used by a broker-dealer in connection
with resales of exchange securities received in exchange for outstanding
securities where the outstanding securities were acquired by such broker-dealer
as a result of market-making activities or other trading activities. Pursuant
to the registration rights agreement, we agreed to make this prospectus
available to any such broker-dealer for use in connection with any such resale
for the one-year period ending on the first anniversary of the expiration date.

   Each broker-dealer that receives exchange securities for its own account in
exchange for outstanding securities, where such securities were acquired by
such broker dealer as a result of market-making activities or other trading
activities, must acknowledge that it will deliver a prospectus in connection
with any resale of such exchange securities. See "Plan of Distribution."

   Shelf Registration Statement.  We will, at our cost, (a) file with the
Commission one or more shelf registration statements covering resales of the
outstanding securities as soon as practicable, but, in any event, within 360
days after the issue date of the outstanding securities, (b) use our best
efforts to cause the shelf registration statement to be declared effective
under the Securities Act and (c) use our best efforts to keep the shelf
registration statement continually effective, supplemented and amended to the
extent necessary to ensure that it is available for resales of securities by
the holders of Transfer Restricted Securities for a period of at least two
years following the effective date of such shelf registration statement (or
such shorter period that will terminate when all the securities covered by such
shelf registration statement have been sold pursuant to such shelf registration
statement or are otherwise no longer Transfer Restricted Securities), if:

      (1) we are not required to file the exchange offer registration statement
   or not permitted to consummate the exchange offers because the exchange
   offers are not permitted by applicable law or Commission policy or

      (2) any initial purchaser so requests with respect to outstanding
   securities that are not eligible to be exchanged for exchange securities in
   the exchange offers or notifies us that it may not resell the exchange
   securities acquired by it in the exchange offers to the public without
   delivering a prospectus and the prospectus contained in the exchange offer
   registration statements is not appropriate or available for such resales.

   We will, in the event of the filing of the shelf registration statement,
provide to each holder of the outstanding securities copies of the prospectus
which is a part of the shelf registration statement, notify each such holder
when the shelf registration statement for the outstanding securities has become
effective and take certain other action as is required to permit unrestricted
resales of the outstanding securities. A holder of outstanding securities who
sells such outstanding securities pursuant to the shelf registration statement
generally will (1) be required to be named as a selling security holder in the
related prospectus, (2) be subject to certain of the civil liability provisions
under the Securities Act in connection with such sales and (3) be bound by the
provisions of
the registration rights agreement which are applicable to the holder (including
certain indemnification obligations).

Terms of the Exchange Offers

   Upon satisfaction or waiver of all the conditions of the exchange offers, we
will accept any and all outstanding securities properly tendered and not
withdrawn prior to the expiration date and will issue the

                                      13



exchange securities promptly after acceptance of the outstanding securities.
See "--Conditions to the Exchange Offers" and "Procedures for Tendering
Outstanding Securities." We will issue $1,000 principal amount of exchange
securities in exchange for each $1,000 principal amount of outstanding
securities accepted in the exchange offers. As of the date of this prospectus,
there are $365,000,000 aggregate principal amount of outstanding bonds and
$400,000,000 aggregate principal amount of outstanding notes. Holders may
tender some or all of their outstanding securities pursuant to the exchange
offers. However, outstanding securities may be tendered only in integral
multiples of $1,000.

   The exchange securities are identical to the outstanding securities except
for the elimination of certain transfer restrictions and registration rights.
The exchange securities will evidence the same debt as the outstanding
securities and will be issued pursuant to, and entitled to the benefits of, the
respective indentures pursuant to which the outstanding securities were issued
and each will be deemed one issue of securities, together with the outstanding
securities.

   This prospectus, together with the letter of transmittal, is being sent to
all registered holders and to others believed to have beneficial interests in
the outstanding securities. Holders of outstanding securities do not have any
appraisal or dissenters' rights under the indentures in connection with the
exchange offers. We intend to conduct the exchange offers in accordance with
the applicable requirements of the Securities Act, the Exchange Act and the
rules and regulations of the Commission promulgated thereunder.

   For purposes of the exchange offers, we will be deemed to have accepted
validly tendered outstanding securities when, and as if, we have given oral or
written notice thereof to the appropriate exchange agent. Each exchange agent
will act as our agent for the purpose of distributing the appropriate exchange
securities from us to the tendering holders. If we do not accept any tendered
outstanding securities because of an invalid tender, the occurrence of certain
other events set forth in this prospectus or otherwise, we will return the
unaccepted outstanding securities, without expense, to the tendering holder
thereof as promptly as practicable after the expiration date.

   Holders who tender outstanding securities in the exchange offers will not be
required to pay brokerage commissions or fees or, except as set forth below
under "--Transfer Taxes," transfer taxes with respect to the exchange of
outstanding securities pursuant to the exchange offers. We will pay all charges
and expenses, other than certain applicable taxes, in connection with the
exchange offers. See "--Fees and Expenses."

Expiration Date; Extensions; Amendments

   The term "expiration date" shall mean 5:00 p.m., New York City time,
on       , 2002, for each exchange offer unless we, in our sole discretion,
extend an exchange offer, in which case the term "expiration date" shall mean
the latest date and time to which the exchange offer is extended. In order to
extend an exchange offer, we will notify the exchange agent by oral or written
notice and each appropriate registered holder by means of press release or
other public announcement of any extension, in each case, prior to 9:00 a.m.,
New York City time, on the next business day after the previously scheduled
expiration date. We reserve the right, in our sole discretion, (1) to delay
accepting any outstanding securities, (2) to extend each exchange offer, (3) to
terminate each exchange offer if each condition set forth below under
"--Conditions to the Exchange Offers" shall not have been satisfied, or (4) to
amend the terms of the exchange offer in any manner. We will notify the
appropriate exchange agent of any delay, extension, termination or amendment by
oral or written notice. We will additionally
notify each registered holder of any amendment. We will give to the appropriate
exchange agent written confirmation of any oral notice.

Exchange Date

   As soon as practicable after the close of each exchange offer we will accept
for exchange all outstanding securities properly tendered and not validly
withdrawn prior to 5:00 p.m., New York City time, on the expiration date in
accordance with the terms of this prospectus and the letter of transmittal.

                                      14



Conditions to the Exchange Offers

   Notwithstanding any other provisions of the exchange offers, and subject to
our obligations under the registration rights agreement, we (1) shall not be
required to accept any outstanding securities for exchange, (2) shall not be
required to issue exchange securities in exchange for any outstanding
securities and (3) may terminate or amend an exchange offer if, at any time
before the acceptance of outstanding securities for exchange, any of the
following events shall occur:

      (1) any injunction, order or decree shall have been issued by any court
   or any governmental agency that would prohibit, prevent or otherwise
   materially impair our ability to proceed with the exchange offer;

      (2) any change, or any development involving a prospective change, in our
   business or financial affairs or any of our subsidiaries has occurred which,
   in our sole judgment, might materially impair our ability to proceed with an
   exchange offer or materially impair the contemplated benefits of such
   exchange offer to us;

      (3) any law, statute, rule or regulation is proposed, adopted or enacted
   which, in our sole judgment, might materially impair our ability to proceed
   with an exchange offer or materially impair the contemplated benefits of the
   exchange offer to us;

      (4) any governmental approval has not been obtained, which approval we
   shall, in our sole discretion, deem necessary for the consummation of the
   exchange offer as contemplated hereby; or

      (5) the exchange offer will violate any applicable law or any applicable
   interpretation of the staff of the Commission.

   The foregoing conditions are for our sole benefit and may be asserted by us
regardless of the circumstances giving rise to any such condition or may be
waived by us in whole or in part at any time and from time to time in our sole
discretion. Our failure at any time to exercise any of the foregoing rights
shall not be deemed a waiver of any such right and such right shall be deemed
an ongoing right which may be asserted at any time and from time to time.

   In addition, we will not accept for exchange any outstanding securities
tendered, and no exchange securities will be issued in exchange for any such
outstanding securities, if at such time any stop order shall be threatened by
the Commission or be in effect with respect to the registration statement of
which this prospectus is a part or the qualification of the indenture for the
bonds or the notes, as the case may be, under the Trust Indenture Act of 1939,
as amended.

   Neither exchange offer is conditioned on any minimum aggregate principal
amount of outstanding securities being tendered for exchange.

   The exchange offers are separate transactions and the consummation of the
bonds exchange offer is not conditioned upon the consummation of the notes
exchange offer and vice versa.

Consequences of Failure to Exchange

   Any outstanding securities not tendered pursuant to the exchange offers will
remain outstanding and continue to accrue interest. The outstanding securities
will remain "restricted securities" within the meaning of the Securities Act.
Accordingly, prior to the date that is one year after the later of the issue
date and the last date on which we or any of our affiliates was the owner of
the outstanding securities, the outstanding securities may be resold only (1)
to us, (2) to a person who the seller reasonably believes is a "qualified
institutional buyer" purchasing for its own account or for the account of
another "qualified institutional buyer" in compliance with the resale
limitations of Rule 144A, (3) to an Institutional Accredited Investor that,
prior to the transfer, furnishes to the trustee a written certification
containing certain representations and agreements relating to the restrictions
on transfer of the securities (the form of this letter can be obtained from the
trustee), (4) pursuant to the

                                      15



limitations on resale provided by Rule 144 under the Securities Act, (5)
pursuant to the resale provisions of Rule 904 of Regulation S under the
Securities Act, (6) pursuant to an effective registration statement under the
Securities Act, or (7) pursuant to any other available exemption from the
registration requirements of the Securities Act, subject in each of the
foregoing cases to compliance with applicable state securities laws. As a
result, the liquidity of the market for non-tendered outstanding securities
could be adversely affected upon completion of the exchange offers.

Fees and Expenses

   We will not make any payments to brokers, dealers or others soliciting
acceptances of the exchange offers. The principal solicitation is being made by
mail; however, additional solicitations may be made in person or by telephone
by our officers and employees.

   Expenses incurred in connection with the exchange offers will be paid by us.
Such expenses include, among others, the fees and expenses of the trustee and
the exchange agent, accounting and legal fees, printing costs and other
miscellaneous fees and expenses.

Accounting Treatment

   We will not recognize any gain or loss for accounting purposes upon the
consummation of the exchange offers. We will amortize the expenses of the
exchange offers as additional interest expense over the term of the exchange
securities.

Procedures for Tendering Outstanding Securities

   The tender of outstanding securities pursuant to any of the procedures set
forth in this prospectus and in the letter of transmittal will constitute a
binding agreement between the tendering holder and us in accordance with the
terms and subject to the conditions set forth in this prospectus and in the
letter of transmittal. The tender of outstanding securities will constitute an
agreement to deliver good and marketable title to all tendered outstanding
securities prior to the expiration date free and clear of all liens, charges,
claims, encumbrances, interests and restrictions of any kind.

   Except as provided in "--Guaranteed Delivery Procedures," unless the
outstanding securities being tendered are deposited by you with the appropriate
exchange agent prior to the expiration date and are accompanied by a properly
completed and duly executed letter of transmittal, we may, at our option,
reject the tender. Issuance of exchange securities will be made only against
deposit of tendered outstanding securities and delivery of all other required
documents. Notwithstanding the foregoing, DTC participants tendering through
its Automated
Tender Offer Program ("ATOP") will be deemed to have made valid delivery where
the exchange agent receives an agent's message prior to the expiration date.

   Accordingly, to properly tender outstanding securities, the following
procedures must be followed:

   Securities held through a Custodian.  Each beneficial owner holding
outstanding securities through a DTC participant must instruct the DTC
participant to cause its outstanding securities to be tendered in accordance
with the procedures set forth in this prospectus.

   Securities held through DTC.  Pursuant to an authorization given by DTC to
the DTC participants, each DTC participant holding outstanding securities
through DTC must (1) electronically transmit its acceptance through ATOP, and
DTC will then edit and verify the acceptance, execute a book-entry delivery to
the exchange agent's account at DTC and send an agent's message to the exchange
agent for its acceptance, or (2) comply with the guaranteed delivery procedures
set forth below and in a notice of guaranteed delivery. See "--Guaranteed
Delivery Procedures--Securities held through DTC."

                                      16



   The exchange agents will (promptly after the date of this prospectus)
establish accounts at DTC for purposes of the exchange offers with respect to
outstanding securities held through DTC. Any financial institution that is a
DTC participant may make book-entry delivery of interests in outstanding
securities into the exchange agent's account through ATOP. However, although
delivery of interests in the outstanding securities may be effected through
book-entry transfer into the exchange agent's account through ATOP, an agent's
message in connection with such book-entry transfer, and any other required
documents, must be, in any case, transmitted to and received by the exchange
agent at its address set forth under "--Exchange Agents," or the guaranteed
delivery procedures set forth below must be complied with, in each case, prior
to the expiration date. Delivery of documents to DTC does not constitute
delivery to an exchange agent. The confirmation of a book-entry transfer into
an exchange agent's account at DTC as described above is referred to herein as
a "Book-Entry Confirmation."

   The term "agent's message" means a message transmitted by DTC to, and
received by, the appropriate exchange agent and forming a part of the
book-entry confirmation, which states that DTC has received an express
acknowledgment from each DTC participant tendering through ATOP that such DTC
participant has received a letter of transmittal and agrees to be bound by the
terms of the letter of transmittal and that we may enforce such agreement
against such DTC participants.

   Cede & Co., as the holder of the global security, will tender a portion of
the global security equal to the aggregate principal amount due at the stated
maturity for which instructions to tender are given by DTC participants.

   By tendering, each holder and each DTC participant will represent to us
that, among other things, (1) it is not our affiliate, (2) it is not a
broker-dealer tendering outstanding securities acquired directly from us for
its own account, (3) it is acquiring the exchange securities in its ordinary
course of business and (4) it is not engaged in, and does not intend to engage
in, and has no arrangement or understanding with any person to participate in,
a distribution of the exchange securities.

   We will not accept any alternative, conditional, irregular or contingent
tenders (unless waived by us). By executing a letter of transmittal or
transmitting an acceptance through ATOP, as the case may be, each tendering
holder waives any right to receive any notice of the acceptance for purchase of
its outstanding securities.

   We will resolve all questions as to the validity, form, eligibility
(including time of receipt) and acceptance of tendered outstanding securities,
and such determination will be final and binding. We reserve the absolute right
to reject any or all tenders that are not in proper form or the acceptance of
which may, in the opinion of our counsel, be unlawful. We also reserve the
absolute right to waive any condition to either exchange offer and any
irregularities or conditions of tender as to particular outstanding securities.
Our interpretation of the terms and conditions of each exchange offer
(including the instructions in the letter of transmittal) will be final and
binding. Unless waived, any irregularities in connection with tenders must be
cured within such time as we shall determine. We, along with the exchange
agents, shall be under no duty to give notification of defects in such tenders
and shall not incur liabilities for failure to give such notification. Tenders
of outstanding securities will not be deemed to have been made until such
irregularities have been cured or waived. Any outstanding securities received
by an exchange agent that are not properly tendered and as to which the
irregularities have not been cured or waived will be returned by the exchange
agent to the tendering holder, unless otherwise provided in the letter of
transmittal, as soon as practicable following the expiration date.

   LETTERS OF TRANSMITTAL AND OUTSTANDING SECURITIES MUST BE SENT ONLY TO THE
EXCHANGE AGENT. DO NOT SEND LETTERS OF TRANSMITTAL OR OUTSTANDING SECURITIES TO
US OR DTC.

   The method of delivery of outstanding securities, letters of transmittal,
any required signature guarantees and all other required documents, including
delivery through DTC and any acceptance through ATOP, is at the election and
risk of the persons tendering and delivering acceptances or letters of
transmittal and, except as

                                      17



otherwise provided in the applicable letter of transmittal, delivery will be
deemed made only when actually received by the appropriate exchange agent. If
delivery is by mail, it is suggested that the holder use properly insured,
registered mail with return receipt requested, and that the mailing be made
sufficiently in advance of the expiration date to permit delivery to the
appropriate exchange agent prior to the expiration date.

Guaranteed Delivery Procedures

   Securities held through DTC.  DTC participants holding outstanding
securities through DTC who wish to cause their outstanding securities to be
tendered, but who cannot transmit their acceptances through ATOP prior to the
expiration date, may cause a tender to be effected if:

      (1) guaranteed delivery is made by or through a firm or other entity
   identified in Rule 17Ad-15 under the Exchange Act, including:

      .   a bank;

      .   a broker, dealer, municipal securities dealer, municipal securities
          broker, government securities dealer or government securities broker;

      .   a credit union;

      .   a national securities exchange, registered securities association or
          clearing agency; or

      .   a savings institution that is a participant in a Securities Transfer
          Association recognized program;

      (2) prior to the expiration date, the exchange agent receives from any of
   the above institutions a properly completed and duly executed notice of
   guaranteed delivery (by mail, hand delivery, facsimile transmission or
   overnight courier) substantially in the form provided with this prospectus;
   and

      (3) book-entry confirmation and an agent's message in connection
   therewith are received by the exchange agent within three NYSE trading days
   after the date of the execution of the notice of guaranteed delivery.

Withdrawal Rights

   You may withdraw tenders of outstanding securities, or any portion of your
outstanding securities, in integral multiples of $1,000 principal amount due at
the stated maturity, at any time prior to 5:00 p.m., New York City time, on the
expiration date. Any outstanding securities properly withdrawn will be deemed
to be not validly tendered for purposes of the exchange offers.

   Securities held through DTC.  DTC participants holding outstanding
securities who have transmitted their acceptances through ATOP may, prior to
5:00 p.m., New York City time, on the expiration date, withdraw the instruction
given thereby by delivering to the appropriate exchange agent, at its address
set forth under "--Exchange Agents," a written, telegraphic or facsimile notice
of withdrawal of such instruction. Such notice of withdrawal must contain the
name and number of the DTC participant, the principal amount due at the stated
maturity of outstanding securities to which such withdrawal relates and the
signature of the DTC participant. Receipt of such written notice of withdrawal
by the appropriate exchange agent effectuates a withdrawal.

   A withdrawal of a tender of outstanding securities by a DTC participant or a
holder, as the case may be, may be rescinded only by a new transmission of an
acceptance through ATOP or execution and delivery of a new letter of
transmittal, as the case may be, in accordance with the procedures described
herein.

   Securities held by Holders.  Holders may withdraw their tender of
outstanding securities, prior to 5:00 p.m., New York City time, on the
expiration date, by delivering to the exchange agent, at its address set forth
under "--Exchange Agents," a written, telegraphic or facsimile notice of
withdrawal. Any such notice of withdrawal must (1) specify the name of the
person who tendered the outstanding securities to be withdrawn,

                                      18



(2) contain a description of the outstanding securities to be withdrawn and
identify the certificate number or numbers shown on the particular certificates
evidencing such outstanding securities and the aggregate principal amount due
at the stated maturity represented by such outstanding securities and (3) be
signed by the holder of such outstanding securities in the same manner as the
original signature on the letter of transmittal by which such outstanding
securities were tendered (including any required signature guarantees), or be
accompanied by (x) documents of transfer in a form acceptable to us, in our
sole discretion, and (y) a properly completed irrevocable proxy that authorized
such person to effect such revocation on behalf such holder. If the outstanding
securities to be withdrawn have been delivered or otherwise identified to the
exchange agent, a signed notice of withdrawal is effective immediately upon
written, telegraphic or facsimile notice of withdrawal even if physical release
is not yet effected.

   All signatures on a notice of withdrawal must be guaranteed by a recognized
participant in the Securities Transfer Agents Medallion Program, the New York
Stock Exchange Medallion Signature Program or the Stock Exchange Medallion
Program; provided, however, that signatures on the notice of withdrawal need
not be guaranteed if the outstanding securities being withdrawn are held for
the account of any of the institutions listed above under "--Guaranteed
Delivery Procedures."

   A withdrawal of an instruction or a withdrawal of a tender must be executed
by a DTC participant or a holder of outstanding securities, as the case may be,
in the same manner as the person's name appears on its transmission through
ATOP or letter of transmittal, as the case may be, to which such withdrawal
relates. If a notice of withdrawal is signed by a trustee, partner, executor,
administrator, guardian, attorney-in-fact, agent, officer of a corporation or
other person acting in a fiduciary or representative capacity, such person must
so indicate when signing and must submit with the revocation appropriate
evidence of authority to execute the notice of withdrawal. A DTC participant or
a holder may withdraw an instruction or a tender, as the case may be, only if
such withdrawal complies with the provisions of this prospectus.

   A withdrawal of a tender of outstanding securities by a DTC participant or a
holder, as the case may be, may be rescinded only by a new transmission of an
acceptance through ATOP or execution and delivery of a new letter of
transmittal, as the case may be, in accordance with the procedures described
herein.

Transfer Taxes

   Holders of outstanding securities who tender their outstanding securities
for exchange securities will not be obligated to pay any transfer taxes in
connection therewith, except that holders who instruct us to register exchange
securities in the name of, or request that outstanding securities not tendered
or not accepted in the exchange offers be returned to, a person other than the
registered tendering holder will be responsible for the payment of any
applicable transfer tax thereon.

                                      21



                             DESCRIPTION OF BONDS

   In this description, the terms "Westar Energy," "Company," "we," "our,"
"ours" and "us" refer solely to Westar Energy, Inc. and not to any of our
subsidiaries.

Description of Bonds

   The outstanding bonds were and the exchange bonds will be issued under and
secured by the Mortgage and Deed of Trust, dated July 1, 1939, between Western
Resources and BNY Midwest Trust Company, as successor to Harris Trust and
Savings Bank, as Trustee (the "Trustee"), as supplemented and amended by
thirty-four supplemental indentures and as to be supplemented and amended by a
thirty-fifth supplemental indenture (the "Thirty-Fifth Supplemental Indenture")
providing for the outstanding bonds (the original mortgage as so supplemented
and amended we will refer to as the "Mortgage"). We will refer to the
outstanding bonds and the exchange bonds as the "Bonds" and to all the first
mortgage bonds issued or issuable under the Mortgage as the "bonds." What
follows is a brief summary of certain provisions contained in the Mortgage. The
following summaries of certain provisions of the Mortgage do not purport to be
complete and are qualified in their entirety by express reference to the
Mortgage and any supplemental indentures. Capitalized terms used in this
section without definition have the meanings given to such terms in the
Mortgage. In addition, capitalized terms used in "--Repurchase at the Option of
Holders Upon a Change of Control" in this "Description of Bonds" have the same
meanings given to such terms in "Description of Notes--Repurchase at the Option
of Holders upon a Change of Control."

General

   The Bonds are limited to an aggregate principal amount of $365 million. The
Bonds were issued only in the form of registered bonds without coupons in
denominations of $1,000 and multiples thereof. The Bonds are exchangeable for
other bonds in equal aggregate principal amounts without charge to the holders
except for any applicable tax or governmental charge.

   Each Bond bears interest at the rate set forth on the cover, payable
semi-annually on May 1 and November 1 each year. Subject to certain exceptions
provided in the Mortgage, interest is payable at either the office of the
Trustee in Chicago, Illinois, or of the Paying Agent, BNY Midwest Trust
Company, Chicago, Illinois, to the persons in whose names the Bonds are
registered at the close of business on the tenth day prior to the interest
payment date or, at the option of the Company, may be paid by checks mailed to
such persons at their registered addresses. Principal of the Bonds is payable
at either of the agencies of the Company mentioned above.

   There are no improvement and/or maintenance fund for the Bonds.

   The Company maintains routine banking relationships with the Trustee.

Optional Redemption

   At any time, and from time to time, the Company may redeem all or any
portion of the Bonds, after giving the required notice under the Mortgage at a
redemption price equal to the greater of:

      (a) of the principal amount of the Bonds to be redeemed, or

      (b) the sum of the present values of the remaining scheduled payments of
   principal and interest thereon discounted to the date of redemption on a
   semi-annual basis (assuming a 360-day year consisting of twelve 30-day
   months) at the Treasury Rate plus 50 basis points, plus, in either case,
   accrued and unpaid interest, if any, to the redemption date (subject to the
   right of holders of record on the relevant record date to receive interest
   due on the relevant interest payment date).

                                      22



   Any notice to holders of Bonds of such a redemption shall state, among other
things, the redemption price and date. No such redemptions may be conditional
once notice of redemption is given.

Sinking Fund

   There is no mandatory sinking fund payments for the Bonds.

Repurchase at the Option of Holders Upon a Change of Control

   Upon the occurrence of a Change of Control, each holder of Bonds shall have
the right to require the Company to repurchase all or any part of such holder's
Bonds pursuant to the offer described below (the "Change of Control Offer") at
a purchase price (the "Change of Control Purchase Price") equal to 101% of the
principal amount thereof, plus accrued and unpaid interest, if any, to the
purchase date (Thirty-Fifth Supplemental Indenture, Article III).

   Within 30 days following any Change of Control, the Company shall:

      (a) cause a notice of the Change of Control Offer to be sent at least
   once to the Dow Jones News Service or similar business news service in the
   United States; and

      (b) send, by first-class mail, with a copy to the Trustee, to each holder
   of Bonds, at such holder's address appearing in the security register, a
   notice stating:

          (1) that a Change of Control has occurred and a Change of Control
       Offer is being made pursuant to the covenant entitled "--Repurchase at
       the Option of Holders upon a Change of Control" and that all Bonds
       timely tendered will be accepted for payment;

          (2) the Change of Control Purchase Price and the purchase date, which
       shall be, subject to any contrary requirements of applicable law, a
       business day no earlier than 30 days nor later than 60 days from the
       date such notice is mailed;

          (3) the circumstances and relevant facts regarding the Change of
       Control; and

          (4) the procedures that holders of Bonds must follow in order to
       tender their Bonds (or portions thereof) for payment, and the procedures
       that holders of Bonds must follow in order to withdraw an election to
       tender Bonds (or portions thereof) for payment.

   The Company will comply, to the extent applicable, with the requirements of
Section 14(e) of the Exchange Act and any other securities laws or regulations
in connection with the repurchase of Bonds pursuant to a Change of Control
Offer. To the extent that the provisions of any securities laws or regulations
conflict with the provisions of the covenant described hereunder, the Company
will comply with the applicable securities laws and regulations and will not be
deemed to have breached its obligations under the covenant described hereunder
by virtue of such compliance.

   Subject to certain covenants described below, the Company could, in the
future, enter into certain transactions, including acquisitions, refinancings
or other recapitalizations, that would not constitute a Change of Control under
the Mortgage, but that could increase the amount of Debt outstanding at such
time or otherwise affect the Company's capital structure or credit ratings.

   The definition of Change of Control includes a phrase relating to the sale,
transfer, assignment, lease, conveyance or other disposition of "all or
substantially all" the Company's assets. Although there is a developing body of
case law interpreting the phrase "substantially all," there is no precise
established definition of the phrase under applicable law. Accordingly, if the
Company disposes of less than all its assets by any of the means described
above, the ability of a holder of Bonds to require the Company to repurchase
its Bonds may be

                                      23



uncertain. In such a case, holders of the Bonds may not be able to resolve this
uncertainty without resorting to legal action.

   Other Debt of the Company issued in the future may contain prohibitions of
certain events which would constitute a Change of Control or require such Debt
to be repurchased upon a Change of Control. Moreover, the exercise by holders
of Bonds of their right to require the Company to repurchase such Bonds could
cause a default under existing or future Debt of the Company, even if the
Change of Control itself does not, due to the financial effect of such
repurchase on the Company. Finally, the Company's ability to pay cash to
holders of Bonds upon a repurchase may be limited by the Company's then
existing financial resources. There can be no assurance that sufficient funds
will be available when necessary to make any required repurchases. The
Company's failure to purchase Bonds in connection with a Change of Control
would result in a default under the Mortgage. Such a default would, in turn,
constitute a default under existing Debt of the Company, and may constitute a
default under future Debt as well. The Company's obligation to make an offer to
repurchase the Bonds as a result of a Change of Control may be waived or
modified at any time prior to the occurrence of such Change of Control with the
written consent of the holders of a majority in principal amount of the Bonds.
See "--Modification of the Mortgage."

Issuance of Additional Bonds

   Additional bonds ranking equally with the bonds of other series then
outstanding, including the Bonds, may be issued having dates, maturities,
interest rates, redemption prices and other terms as may be determined by our
board of directors. Additional bonds may be issued in principal amounts not
exceeding the sum of:

      (1) 60% (so long as any bonds issued prior to January 1, 1997 remain
   outstanding, and thereafter 70%) of the net bondable value of property
   additions not subject to an unfunded prior lien;

      (2) the principal amount of bonds retired or to be retired (except out of
   trust monies); and

      (3) the amount of cash deposited with the Trustee for such purpose, which
   may thereafter be withdrawn upon the same basis that additional bonds are
   issuable under (1) or (2) above.

   Additional bonds may not be issued on the basis of property additions
subject to an unfunded prior lien. (Mortgage, Article III; Twenty-Eighth,
Twenty-Ninth, Thirtieth, Thirty-First, Thirty-Second, Thirty-Third,
Thirty-Fourth and Thirty-Fifth Supplemental Indentures, Article V.) As of
January 31, 2002, we had approximately $271 million of net bondable property
additions not subject to unfunded prior liens enabling us to issue
approximately $163 million principal amount of additional bonds on such date,
subject to certain other limitations.

   In addition to the restrictions discussed above, so long as any bonds issued
prior to January 1, 1997 remain outstanding additional bonds may not be issued
unless our unconsolidated net earnings available for interest, depreciation and
property retirements for a period of any 12 consecutive months during the
period of 15 calendar months immediately preceding the first day of the month
in which the application for authentication and delivery of additional bonds is
made shall have been not less than the greater of two times the annual interest
charges on, and 10% of the principal amount of, all bonds then outstanding, all
additional bonds then applied for, all outstanding prior lien bonds and all
prior lien bonds, if any, then being applied for. Bonds canceled at or prior to
the time application is made for the issuance of bonds are not deemed to be
outstanding for purposes of calculating interest charges in determining whether
the net earnings test is met for the issuance of additional bonds. Bonds or
prior lien bonds for which monies sufficient for the payment thereof have been
deposited with the Trustee are not considered outstanding for this purpose.

   The net earnings test referred to in the previous paragraph need not be
satisfied to issue additional bonds:

   .   on the basis of property additions subject to an unfunded prior lien
       which simultaneously will become a funded prior lien, if application for
       the issuance of the additional bonds is made at any time after a date
       two years prior to the date of the maturity of the bonds secured by the
       prior lien, and

                                      24



   .   on the basis of the payment at maturity of bonds heretofore issued by
       us, or the redemption, conversion or purchase of bonds, after a date two
       years prior to the date on which those bonds mature.

   We have reserved the right to amend the Mortgage to eliminate the foregoing
requirement. See "--Modification of the Mortgage."

   Based on our results for the twelve months ended January 31, 2002, and
giving effect to the repayment of $100 million principal amount of bonds
maturing on August 15, 2002, and $397.8 million principal amount of bonds
released as collateral from credit facilities, we could issue approximately
$365 million principal amount of additional bonds (assuming an interest rate of
7 7/8%). The Bonds have been issued against the principal amount of bonds
retired or to be retired and/or additional property additions. (Mortgage,
Article III, Sections 3, 4, and 6; Twenty-Eighth, Twenty-Ninth, Thirtieth,
Thirty-First, Thirty-Second, Thirty-Third, Thirty-Fourth and Thirty-Fifth
Supplemental Indentures, Article V.)

Release and Substitution of Property

   The Mortgage provides that, subject to various limitations, property may be
released from the lien thereof on the basis of cash deposited with the Trustee,
bonds or purchase money obligations delivered to the Trustee, prior lien bonds
delivered to the Trustee, or unfunded net property additions certified to the
Trustee. (Mortgage, Article VII.) The Mortgage also in effect permits the
withdrawal of cash against the certification to the Trustee of gross property
additions at 100%, or the net bondable value of property additions at 60% (so
long as any bonds issued prior to January 1, 1997 remain outstanding, and
thereafter 70%), or the deposit with the Trustee of bonds we have acquired.
(Mortgage, Article VIII; Sections 1-3; Twenty-Eighth, Twenty-Ninth, Thirtieth,
Thirty-First, Thirty-Second, Thirty-Third, Thirty-Fourth and Thirty-Fifth
Supplemental Indentures, Article V.) The Mortgage contains special provisions
with respect to the release of all or substantially all of our gas and electric
properties. (Twenty-Eighth, Twenty-Ninth, Thirtieth, Thirty-First,
Thirty-Second, Thirty-Third, Thirty-Fourth and Thirty-Fifth Supplemental
Indentures, Article IV, Sections 2 and 3.) We have reserved the right to amend
the Mortgage to change the release and substitution provisions. See
"--Modification of the Mortgage."

Priority and Security

   In the opinion of Larry D. Irick, Esq., our Vice President and Corporate
Secretary, the Bonds are secured, equally and ratably with all of the bonds now
outstanding or hereafter issued under the Mortgage, by the lien on
substantially all of our fixed property and franchises purported to be conveyed
by the Mortgage, subject to the exceptions referred to below, to certain minor
leases and easements, permitted liens, exceptions and reservations in the
instruments by which we acquired title to our property and the prior lien of
the Trustee for compensation, expenses and liability. In the opinion of Mr.
Irick, the Mortgage constitutes a lien on after-acquired property of the
character intended to be mortgaged property.

   Excepted from the lien of the Mortgage are:

   .   cash and accounts receivable;

   .   contracts or operating agreements;

   .   securities not pledged under the Mortgage;

   .   electric energy, gas, water, materials and supplies held for consumption
       in operation or held in advance of use for fixed capital purposes; and

   .   merchandise, appliances and supplies held for resale or lease to
       customers.

   There is further expressly excepted any property of any other corporation,
all the securities of which may be owned or later acquired by us. (Granting
Clauses of the Mortgage.) The lien of the Mortgage does not apply to property
of KGE so long as KGE remains our wholly owned subsidiary, to the stock of KGE
owned by us or to

                                      25



the stock of any of our other subsidiaries. The Mortgage permits our
consolidation or merger with, or the conveyance of all or substantially all of
our property to, any other corporation; provided, that the successor
corporation assumes the due and punctual payment of the principal and interest
on the bonds of all series then outstanding under the Mortgage and assumes the
due and punctual performance of all the covenants and conditions of the
Mortgage (Mortgage, Article XII, Section 1); provided further, however, holders
of Bonds may require us to purchase all or part of their Bonds as described
more fully under "--Repurchase at the Option of Holders upon a Change of
Control."

Modification of the Mortgage

   Except as provided in "--Repurchase at the Option of Holders upon a Change
of Control," the Mortgage may be modified or altered, subject to our rights and
obligations and the rights of holders of bonds, by the written consent of the
holders of at least 60% in principal amount of the bonds, and, if the rights of
one or more, but less than all, series of bonds then outstanding are to be
affected by action taken pursuant to such consent, then also by consent of the
holders of at least 60% in principal amount of each series of bonds so
affected. No modification or alteration may be made which will permit the
extension of the time or times of payment of the principal of, and premium, if
any, or interest (including additional interest) on any bond or a reduction in
the rate of interest thereon, or otherwise affect the terms of payment of the
principal of, and premium, if any, or interest (including additional interest)
on any bond or a reduction in the rate of interest thereon or reduce the
percentages required for the taking of any action thereunder. Bonds owned by us
or any affiliated corporation are excluded for the purpose of any vote,
determination of a quorum or consent. (Mortgage, Article XV, Section 6;
Twenty-Eighth, Twenty-Ninth, Thirtieth, Thirty-First, Thirty-Second,
Thirty-Third, Thirty-Fourth and Thirty-Fifth Supplemental Indentures, Article
V, Sections 3 and 4.)

   The Mortgage also provides that without the consent of any holder of any
bond issued thereunder, the right of such holder to receive payment of the
principal of, and premium, if any, or interest (including additional interest)
on, on or after the respective due dates expressed in such bond, or to
institute suit for the enforcement of any payment on or after such respective
due dates shall not be impaired or affected. (Mortgage, Article XXII, Section
2.)

   We have reserved the right, subject to appropriate corporate action, but
without the consent or other action of holders of bonds of any series created
after January 1, 1997, to make amendments to the Mortgage to permit, unless an
event of default shall have happened and be continuing, or shall happen as a
result of making or granting an application,

      1.  the release from the lien of the Mortgage of any mortgaged property
   if the fair value of all of the property constituting the trust estate
   (excluding the mortgaged property to be released but including any mortgaged
   property to be acquired by us with the proceeds of, or otherwise in
   connection with, such release) equals or exceeds an amount equal to 10/7ths
   of the aggregate principal amount of outstanding bonds and any prior lien
   bonds outstanding at the time of such release;

      2.  in the event we are unable to obtain a release of property as
   described in clause (1), the release from the lien of the Mortgage of any
   property constituting part of the trust estate if the fair value thereof is
   less than 1/2 of 1% of the aggregate principal amount of bonds and prior
   lien bonds outstanding at the time of such release; provided, that the
   property released pursuant to this clause (2) in any period of
   12 consecutive calendar months shall not exceed 1% of such bonds and prior
   lien bonds;

      3.  the deletion of the net earnings test for the issuance of additional
   bonds;

      4.  the deletion of the requirement to obtain an independent engineer's
   certificate in connection with certain releases of property from the lien of
   the Mortgage; and

      5.  the deletion of a financial test to be met by another corporation in
   the event of our consolidation or merger into or our sale of our property as
   an entirety or substantially as an entirety to such other corporation.
   (Thirty-Third, Thirty-Fourth and Thirty-Fifth Supplemental Indentures,
   Article V.)

                                      26



Events of Default

   An event of default under the Mortgage includes:

   .   default in the payment of the principal of any bond when the same shall
       become due and payable, whether at maturity or otherwise;

   .   default continuing for 30 days in the payment of any installment of
       interest on any bond or in the payment or satisfaction of any sinking
       fund obligation;

   .   default in performance or observance of any other covenant, agreement or
       condition in the Mortgage continuing for a period of 60 days after
       written notice to us thereof by the Trustee or by the holders of not
       less than 15% of the aggregate principal amount of all bonds then
       outstanding;

   .   failure to discharge or stay within 30 days a final judgment against us
       for the payment of money in excess of $100,000; and

   .   certain events in bankruptcy, insolvency or reorganization. (Mortgage,
       Article IX, Section 1.)

   The Trustee is required, within 90 days after the occurrence thereof, to
give to the holders of the bonds notice of all defaults known to the Trustee
unless such defaults shall have been cured before the giving of such notice
(the term "defaults" for such purposes being defined to be the events specified
above, not including any periods of grace); provided, however, that except in
the case of default in the payment of the principal of, and premium, if any, or
interest (including additional interest) on any of the bonds, or in the payment
or satisfaction of any sinking or purchase fund installment, the Trustee shall
be protected in withholding notice if and so long as the Trustee in good faith
determines that the withholding of notice is in the interests of the holders of
the bonds and, in the case of any default specified in the third bullet point
above, no notice shall be given until at least 60 days after the occurrence
thereof. (Mortgage, Article XIX, Section 3.) The Trustee is under no obligation
to defend or initiate any action under the Mortgage which would result in the
incurring of non-reimbursable expenses unless one or more of the holders of
bonds, including the Bonds, furnishes the Trustee with reasonable indemnity
against such expenses. In the event of a default, the Trustee is not required
to act unless requested to act by holders of at least 25% in aggregate
principal amount of the bonds then outstanding. (Mortgage, Article IX, Sections
1 and 4, Article XIII, Section 2 and Article XXI, Section 6.) In addition, a
majority of the holders of the bonds have the right to direct all proceedings
under the Mortgage; provided, the Trustee is indemnified to its satisfaction.
(Mortgage, Article IX, Section 11.)

                             DESCRIPTION OF NOTES

   In this description the terms "Westar Energy," "we," "Company," "our,"
"ours" and "us" refer solely to Westar Energy, Inc. and not to any of our
subsidiaries.

Description of Debt Securities

   The outstanding notes and the exchange notes are a series of unsecured debt
securities (the "Debt Securities"). The outstanding notes were and the exchange
notes will be under an Indenture and a Securities Resolution (together, the
"Indenture") between the Company and Deutsche Bank Trust Company Americas, as
trustee (the "Note Trustee"). The following summaries of certain provisions of
the Indenture establishing the terms of the Notes do not purport to be complete
and are qualified in their entirety by express reference to the Indenture. For
purposes of this section, the term "Notes" refers to both the outstanding notes
and the exchange notes. Certain capitalized terms used in this section,
"Description of Notes," are used with the meanings set forth under "--Certain
Definitions," below. Certain other capitalized terms used in this section
without definition have the meanings given to such terms in the Indenture.

General

   The Indenture does not limit the amount of Debt Securities that can be
issued thereunder and provides that the Debt Securities may be issued from time
to time in one or more series pursuant to the terms of one or more Securities
Resolutions creating such series. The Debt Securities are unsecured and rank on
a parity with all other unsecured and unsubordinated senior debt of the
Company, but are effectively junior to any existing and future secured Debt to
the extent of the value of the collateral securing the Debt. The Debt
Securities are senior to all indebtedness of the Company which by its terms is
made subordinate to the Debt Securities.

Ranking

   The Notes are:

   .   senior unsecured obligations of the Company;

   .   equal in right of payment ("pari passu") with all existing and future
       Senior Debt; and

   .   senior in right of payment to all existing and future Subordinated
       Obligations.

   As of March 31, 2002, after giving effect to the issuance of the outstanding
bonds and outstanding notes and our use of the net proceeds to retire debt, we
would have had indebtedness on our consolidated balance sheet of approximately
$3.38 billion and $220 million of mandatorily redeemable preferred securities.
Approximately $1.16 billion would have been senior with respect to the assets
of our Subsidiaries because our Subsidiaries are the obligors under such
indebtedness, and $724 million would have been senior indebtedness representing
our secured obligations. Our total indebtedness would have included $298
million of outstanding borrowings under our $400 million revolving credit
facility.

   The Company only has a stockholder's claim on the assets of its
Subsidiaries. This stockholder's claim is junior to the claims that creditors
of the Company's Subsidiaries have against those Subsidiaries. Holders of the
Notes are only creditors of the Company, and not of any of its Subsidiaries. As
a result, all the existing and future liabilities of the Company's
Subsidiaries, including any claims of trade creditors and preferred
stockholders, are effectively senior to the Notes with respect to the assets of
the Subsidiaries.

   The Company's Subsidiaries have significant liabilities, including
contingent liabilities. Although the Indenture contains limitations on the
amount of additional Debt that the Company and any Restricted Subsidiary may
Incur, the amounts of such Debt could be substantial. In addition, the
Indenture does not restrict the Incurrence of Debt by the Company's
Unrestricted Subsidiaries, and such Debt would be effectively senior in right
of payment to the Notes with respect to the assets of those Subsidiaries. See
"--Certain Covenants--Limitation on Debt."

                                      28



   The Notes are obligations exclusively of the Company. To the extent that the
Company's ability to service its debt, including the Notes, may be dependent
upon the earnings of the Company's Subsidiaries, the Company's ability to do so
will be dependent on the Subsidiaries' ability to distribute those earnings to
the Company as dividends, loans or other payments. There are no loan documents
or other agreements that restrict the ability of the Company's Restricted
Subsidiaries to pay dividends, extend loans or make other payments to the
Company. Certain laws restrict the ability of the Company's Restricted
Subsidiaries to pay dividends, extend loans or make other payments to the
Company.

   The Notes are unsecured obligations. Secured Debt of the Company is
effectively senior to the Notes to the extent of the value of the assets
securing such secured Debt. Substantially all of the utility assets of the
Company and KGE, a Restricted Subsidiary, are subject to Liens under the
Mortgage pursuant to which the bonds are issued and under the KGE mortgage
pursuant to which KGE's bonds are issued, respectively.

   As of March 31, 2002, $724 million of the bonds were outstanding. The
Mortgage provides that no other Debt equal with respect to the property subject
to the Lien of the Mortgage or senior to such bonds in right of payment may be
Incurred by the Company except as permitted thereunder.

   See "Risk Factors--Risks Relating to the Exchange Securities--Our
substantial indebtedness could impair our financial condition and our ability
to fulfill our obligations under our existing indebtedness as well as under the
exchange securities" and "--The exchange securities are effectively
subordinated to all debt and other liabilities of our subsidiaries with respect
to the assets of our subsidiaries."

Optional Redemption

   At any time, and from time to time, the Company may redeem all or any
portion of the Notes, after giving the required notice under the Indenture at a
redemption price equal to the greater of:

      (a) 100% of the principal amount of the Notes to be redeemed, or

      (b) the sum of the present values of the remaining scheduled payments of
   principal and interest thereon discounted to the date of redemption on a
   semi-annual basis (assuming a 360-day year consisting of twelve 30-day
   months) at the Treasury Rate plus 75 basis points,

plus, in either case, accrued and unpaid interest, if any, to the redemption
date (subject to the right of holders of record on the relevant record date to
receive interest due on the relevant interest payment date).

   Any notice to holders of Notes of such a redemption shall state, among other
things, the redemption price and date. No such redemptions may be conditional
once notice of redemption is given.

   At any time and from time to time, prior to May 1, 2004, the Company may
redeem up to a maximum of 35% of the original aggregate principal amount of the
Notes with the proceeds of one or more Public Equity Offerings at a redemption
price equal to 109.75% of the principal amount thereof, plus accrued and unpaid
interest, if any, to the redemption date (subject to the right of holders of
record on the relevant record date to receive interest due on the relevant
interest payment date); provided, however, that after giving effect to any such
redemption, at least 65% of the original aggregate principal amount of the
Notes remains outstanding. Any such redemption shall be made within 75 days of
such Public Equity Offering upon not less than 30 nor more than 60 days' prior
notice.

Sinking Fund

   There is no mandatory sinking fund payments for the Notes.

                                      29



Repurchase at the Option of Holders Upon a Change of Control

   Upon the occurrence of a Change of Control, each holder of Notes shall have
the right to require the Company to repurchase all or any part of such holder's
Notes pursuant to the offer described below (the "Change of Control Offer") at
a purchase price (the "Change of Control Purchase Price") equal to 101% of the
principal amount thereof, plus accrued and unpaid interest, if any, to the
purchase date.

   Within 30 days following any Change of Control, the Company shall:

      (a) cause a notice of the Change of Control Offer to be sent at least
   once to the Dow Jones News Service or similar business news service in the
   United States; and

      (b) send, by first-class mail, with a copy to the Note Trustee, to each
   holder of Notes, at such holder's address appearing in the security
   register, a notice stating:

          (1) that a Change of Control has occurred and a Change of Control
       Offer is being made pursuant to the covenant entitled "Repurchase at the
       Option of Holders Upon a Change of Control" and that all Notes timely
       tendered will be accepted for payment;

          (2) the Change of Control Purchase Price and the purchase date, which
       shall be, subject to any contrary requirements of applicable law, a
       business day no earlier than 30 days nor later than 60 days from the
       date such notice is mailed;

          (3) the circumstances and relevant facts regarding the Change of
       Control; and

          (4) the procedures that holders of Notes must follow in order to
       tender their Notes (or portions thereof) for payment, and the procedures
       that holders of Notes must follow in order to withdraw an election to
       tender Notes (or portions thereof) for payment.

   The Company will comply, to the extent applicable, with the requirements of
Section 14(e) of the Exchange Act and any other securities laws or regulations
in connection with the repurchase of Notes pursuant to a Change of Control
Offer. To the extent that the provisions of any securities laws or regulations
conflict with the provisions of the covenant described hereunder, the Company
will comply with the applicable securities laws and regulations and will not be
deemed to have breached its obligations under the covenant described hereunder
by virtue of such compliance.

   Subject to certain covenants described below, the Company could, in the
future, enter into certain transactions, including acquisitions, refinancings
or other recapitalizations, that would not constitute a Change of Control under
the Indenture, but that could increase the amount of Debt outstanding at such
time or otherwise affect the Company's capital structure or credit ratings.

   The definition of Change of Control includes a phrase relating to the sale,
transfer, assignment, lease, conveyance or other disposition of "all or
substantially all" the Company's assets. Although there is a developing body of
case law interpreting the phrase "substantially all," there is no precise
established definition of the phrase under applicable law. Accordingly, if the
Company disposes of less than all its assets by any of the means described
above, the ability of a holder of Notes to require the Company to repurchase
such holder's Notes may be uncertain. In such a case, holders of the Notes may
not be able to resolve this uncertainty without resorting to legal action.

   Other Debt of the Company issued in the future may contain prohibitions on
certain events which would constitute a Change of Control or require such Debt
to be repurchased upon a Change of Control. Moreover, the exercise by holders
of Notes of their right to require the Company to repurchase such Notes could
cause a default under existing or future Debt of the Company, even if the
Change of Control itself does not, due to the financial effect of such
repurchase on the Company. Finally, the Company's ability to pay cash to
holders of Notes upon a repurchase may be limited by the Company's then
existing financial resources. There can be no assurance that sufficient funds
will be available when necessary to make any required repurchases. The
Company's failure to purchase Notes in connection with a Change of Control
would result in a default under the Indenture. Such a

                                      30



default would, in turn, constitute a default under existing Debt of the
Company, and may constitute a default under future Debt as well. The Company's
obligation to make an offer to repurchase the Notes as a result of a Change of
Control may be waived or modified at any time prior to the occurrence of such
Change of Control with the written consent of the holders of a majority in
principal amount of the Notes. See "--Amendments and Waivers."

Certain Covenants

   Covenant Suspension.  Set forth below are summaries of certain covenants
applicable to the Notes. During any period of time that the Notes have
Investment Grade Ratings from the Required Rating Agencies, the Company and any
Restricted Subsidiary will not be subject to the following provisions of the
Indenture:

   .   "--Limitation on Debt,"

   .   "--Limitation on Restricted Payments,"

   .   "--Limitation on Asset Sales,"

   .   "--Limitation on Restrictions on Distributions from any Restricted
       Subsidiary,"

   .   "--Limitation on Transactions with Affiliates,"

   .   clause (x) of the fourth paragraph (and such clause (x) as referred to
       in the second paragraph) of "--Designation of Restricted and
       Unrestricted Subsidiaries,"

   .   "--Limitation on Company's Business,"

   .   "--Repurchase at the Option of Holders Upon a Change of Control" and

   .   clauses (e) and (f) of the first paragraph of "--Merger, Consolidation
       and Sale of Property"

(collectively, the "Suspended Covenants"). In the event that the Company and
any Restricted Subsidiary are not subject to the Suspended Covenants for any
period of time as a result of the preceding sentence and, subsequently, a
Rating Agency withdraws its rating or downgrades the rating assigned to the
Notes so that the Notes no longer have Investment Grade Ratings from the
Required Rating Agencies or a Default or Event of Default occurs and is
continuing, then the Company and any Restricted Subsidiary will thereafter
again be subject to the Suspended Covenants and compliance with the Suspended
Covenants with respect to Restricted Payments made after the time of such
withdrawal, downgrade, Default or Event of Default will be calculated in
accordance with the terms of the covenant described below under "--Limitation
on Restricted Payments" as though such covenant had been in effect during the
entire period of time from the Issue Date.

   Limitation on Debt.  The Company shall not, and shall not permit any
Restricted Subsidiary to, Incur, directly or indirectly, any Debt unless, after
giving effect to the application of the proceeds thereof, no Default or Event
of Default would occur as a consequence of such Incurrence or be continuing
following such Incurrence and either:

      (1) if such Debt is Debt of the Company or any Restricted Subsidiary,
   after giving effect to the Incurrence of such Debt and the application of
   the proceeds thereof, the Consolidated Interest Coverage Ratio would be
   greater than 2.00 to 1.00, or

      (2) such Debt is Permitted Debt.

   The term "Permitted Debt" is defined to include the following:

      (a) Debt of the Company evidenced by the Notes and the bonds (including
   bonds pledged to secure Debt under clause (b) below);

                                      31



      (b) Debt of the Company under the Credit Facilities, provided that the
   aggregate principal amount of all such Debt under the Credit Facilities at
   any one time outstanding shall not exceed $1.3 billion, which amount shall
   be permanently reduced by the amount of Net Available Cash used to Repay
   Debt under the Credit Facilities, and not subsequently reinvested in
   Additional Assets or used to purchase Notes or Repay other Debt, pursuant to
   the covenant described under "--Limitation on Asset Sales";

      (c) Capital Expenditure Debt, provided that:

          (1) the aggregate principal amount of such Debt does not exceed the
       Fair Market Value (on the date of the Incurrence thereof) of the
       Property acquired, constructed or leased, and

          (2) the aggregate principal amount of all Debt Incurred pursuant to
       this clause (c) during any calendar year does not exceed $150 million;

      (d) Debt of the Company owing to and held by any Wholly Owned Restricted
   Subsidiary and Debt of a Restricted Subsidiary owing to and held by the
   Company or any Wholly Owned Restricted Subsidiary; provided, however, that
   any subsequent issue or transfer of Capital Stock or other event that
   results in any such Wholly Owned Restricted Subsidiary ceasing to be a
   Wholly Owned Restricted Subsidiary or any subsequent transfer of any such
   Debt (except to the Company or a Wholly Owned Restricted Subsidiary) shall
   be deemed, in each case, to constitute the Incurrence of such Debt by the
   issuer thereof;

      (e) Debt under Interest Rate Agreements entered into by the Company or
   any Restricted Subsidiary for the purpose of limiting interest rate risk in
   the ordinary course of the financial management of the Company or such
   Restricted Subsidiary and not for speculative purposes, provided that the
   obligations under such Agreements are directly related to payment
   obligations on Debt otherwise permitted by the terms of this covenant;

      (f) Debt under Currency Exchange Protection Agreements entered into by
   the Company or any Restricted Subsidiary for the purpose of limiting
   currency exchange rate risks directly related to transactions entered into
   by the Company or such Restricted Subsidiary in the ordinary course of
   business and not for speculative purposes;

      (g) Debt under Commodity Price Protection Agreements entered into by the
   Company or any Restricted Subsidiary in the ordinary course of the financial
   management of the Company or such Restricted Subsidiary and not for
   speculative purposes;

      (h) Debt in connection with one or more standby letters of credit,
   performance bonds and/or collateral margin accounts issued or opened by the
   Company or any Restricted Subsidiary (but not including any Guarantees) in
   the ordinary course of business or pursuant to self-insurance obligations
   and not in connection with the borrowing of money or the obtaining of
   advances or credit;

      (i) Debt outstanding on the Issue Date not otherwise described in clauses
   (a) through (h) above;

      (j) Debt of the Company and the Restricted Subsidiaries in an aggregate
   principal amount outstanding at any one time not to exceed $100 million; and

      (k) Permitted Refinancing Debt Incurred in respect of Debt Incurred
   pursuant to clauses (a), (c) and (i) of clause (2) of this covenant.

   Notwithstanding anything to the contrary contained in this covenant,

      (a) accrual of interest, accretion or amortization of original issue
   discount and the payment of interest or dividends in the form of additional
   Debt will be deemed not to be an incurrence of Debt for purposes of this
   covenant; and

      (b) for purposes of determining compliance with this covenant, in the
   event that an item of Debt (including Acquired Debt) meets the criteria of
   more than one of the categories of Permitted Debt described in clauses (a)
   through (k) of clause (2) of this covenant or is entitled to be incurred
   pursuant to clause (l) of the first paragraph of this covenant, the Company
   will, in its sole discretion, classify (or later reclassify in whole or in
   part, in its sole discretion) such item of Debt in any manner that complies
   with this covenant.

                                      32



   Limitation on Restricted Payments.  The Company shall not make, and shall
not permit any Restricted Subsidiary to make, directly or indirectly, any
Restricted Payment if at the time of, and after giving effect to, such proposed
Restricted Payment,

      (a) a Default or Event of Default shall have occurred and be continuing,

      (b) the Company could not Incur at least $1.00 of additional Debt
   pursuant to clause (1) of the first paragraph of the covenant described
   under "--Limitation on Debt" or

      (c) the aggregate amount of such Restricted Payment and all other
   Restricted Payments declared or made since the Issue Date (the amount of any
   Restricted Payment, if made other than in cash, to be based upon Fair Market
   Value) would exceed an amount equal to the sum of:

          (1) 50% of the aggregate amount of Consolidated Net Income accrued
       during the period (treated as one accounting period) from the beginning
       of the first fiscal quarter during which the Issue Date occurs to the
       end of the most recent fiscal quarter for which financial statements are
       available prior to the date of such Restricted Payment (or if the
       aggregate amount of Consolidated Net Income for such period shall be a
       deficit, minus 100% of such deficit), plus

          (2) Capital Stock Sale Proceeds, plus

          (3) the sum of:

             (A) the aggregate net cash proceeds received by the Company or any
          Restricted Subsidiary from the issuance or sale after the Issue Date
          of convertible or exchangeable Debt that has been converted into or
          exchanged for Capital Stock (other than Disqualified Stock) of the
          Company, and

             (B) the aggregate amount by which Debt (other than Subordinated
          Obligations) of the Company or any Restricted Subsidiary is reduced
          on the Company's consolidated balance sheet on or after the Issue
          Date upon the conversion or exchange of any Debt issued or sold on or
          prior to the Issue Date that is convertible or exchangeable for
          Capital Stock (other than Disqualified Stock) of the Company,

      excluding, in the case of clause (A) or (B):

                 (x) any such Debt issued or sold to the Company or any
              Restricted Subsidiary of the Company, and

                 (y) the aggregate amount of any cash or other Property
              distributed by the Company or such Restricted Subsidiary upon any
              such conversion or exchange,

      plus

          (4) an amount equal to the sum of:

             (A) the net reduction in Investments in any Person other than the
          Company or a Restricted Subsidiary resulting from dividends,
          repayments of loans or advances or other transfers of Property, in
          each case to the Company or any Restricted Subsidiary from such
          Person, and

             (B) the portion (proportionate to the Company's equity interest in
          such Unrestricted Subsidiary) of the Fair Market Value of the net
          assets of an Unrestricted Subsidiary at the time such Unrestricted
          Subsidiary is designated a Restricted Subsidiary; provided, however,
          that the foregoing sum shall not exceed, in the case of any Person,
          the amount of Investments previously made (and treated as a
          Restricted Payment) by the Company or any Restricted Subsidiary in
          such Person.

   Notwithstanding the foregoing limitation, the Company may:

      (a) pay dividends on its Capital Stock within 75 days of the declaration
   thereof if, on said declaration date, such dividends could have been paid in
   compliance with the Indenture and this covenant; provided, however, that at
   the time of such payment of such dividend, no other Default or Event of
   Default shall have occurred and be continuing (or result therefrom);
   provided further, however, that such dividends shall be included in the
   calculation of the amount of Restricted Payments;

                                      33



      (b) purchase, repurchase, redeem, legally defease, acquire or retire for
   value Capital Stock of the Company or Subordinated Obligations in exchange
   for, or out of the proceeds of the substantially concurrent sale of, Capital
   Stock of the Company (other than Disqualified Stock and other than Capital
   Stock issued or sold to a Subsidiary of the Company); provided, however, that

          (1) such purchase, repurchase, redemption, legal defeasance,
       acquisition or retirement shall be excluded in the calculation of the
       amount of Restricted Payments, and

          (2) the Capital Stock Sale Proceeds from such exchange or sale shall
       be excluded from the calculation pursuant to clause (c)(2) above; and

      (c) purchase, repurchase, redeem, legally defease, acquire or retire for
   value any Subordinated Obligations in exchange for, or out of the proceeds
   of the substantially concurrent sale of, Permitted Refinancing Debt;
   provided, however, that such purchase, repurchase, redemption, legal
   defeasance, acquisition or retirement shall be excluded in the calculation
   of the amount of Restricted Payments;

      (d) repurchase shares of, or options to purchase shares of, common stock
   of the Company or any of its Subsidiaries from current or former officers,
   directors or employees of the Company or any of its Subsidiaries (or
   permitted transferees of such current or former officers, directors or
   employees), pursuant to the terms of agreements (including employment
   agreements) or plans (or amendments thereto) approved by the Board of
   Directors under which such individuals purchase or sell, or are granted the
   option to purchase or sell, shares of such common stock; provided, however,
   that at the time of such repurchase, no other Default or Event of Default
   shall have occurred and be continuing (or result therefrom); provided
   further, however, that such repurchases shall be excluded in the calculation
   of the amount of Restricted Payments;

      (e) make a Restricted Payment, if at the time the Company or any
   Restricted Subsidiary first Incurred a commitment for such Restricted
   Payment, such Restricted Payment could have been made; provided, however,
   that all commitments Incurred and outstanding shall be treated as if such
   commitments were Restricted Payments expended by the Company or such
   Restricted Subsidiary at the time the commitments were Incurred, except that
   commitments Incurred and outstanding that are treated as the Restricted
   Payment expended by the Company or such Restricted Subsidiary and that are
   terminated shall no longer be treated as a Restricted Payment expended by
   the Company or such Restricted Subsidiary upon the termination of such
   commitment;

      (f) pay scheduled dividends on Preferred Stock of the Company or any
   Restricted Subsidiary or on Disqualified Stock of the Company issued
   pursuant to and in compliance with the covenant described under
   "--Limitation on Debt," provided, however, that any such dividends shall be
   included in the calculation of the amount of Restricted Payments;

      (g) pay scheduled cash dividends on the Company's common stock and
   Restricted Share Units at an annual rate not in excess of $1.20 per share,
   provided, however, that any such cash dividends shall be included in the
   calculation of the amount of Restricted Payments;

      (h) make distributions of part or all of the businesses of Protection One
   or Protection One Europe to holders of the Company's Capital Stock;

      (i) repurchase the Cumulative Preferred Stock outstanding as of the Issue
   Date; and

      (j) make Restricted Payments not otherwise permitted hereunder in an
   aggregate amount not in excess of $50 million.

   Limitation on Liens.  So long as any of the Notes are outstanding, the
Company shall not, and shall not permit any Restricted Subsidiary to, directly
or indirectly, Incur or suffer to exist, any Lien (other than Permitted Liens)
upon or with respect to any of its Property of any character, including without
limitation any shares of Capital Stock of any Restricted Subsidiary, without
making effective provision whereby the Notes shall (so long as any such other
creditor shall be so secured) be equally and ratably secured (along with any
other creditor similarly entitled to be secured) by a direct Lien on all
property subject to such Lien (for the avoidance of doubt, the foregoing
restriction shall not apply to Permitted Liens securing Debt of the Company).

                                      34



   Limitation on Asset Sales.  The Company shall not, and shall not permit any
Restricted Subsidiary to, directly or indirectly, consummate any Asset Sale
unless:

      (a) the Company or such Restricted Subsidiary receives consideration at
   the time of such Asset Sale at least equal to the Fair Market Value of the
   Property subject to such Asset Sale;

      (b) at least 75% of the consideration paid to the Company or such
   Restricted Subsidiary in connection with such Asset Sale is in the form of
   cash or Cash Equivalents or the assumption by the purchaser of liabilities
   of the Company or such Restricted Subsidiary (other than liabilities that
   are by their terms subordinated to the Notes) as a result of which the
   Company and such Restricted Subsidiary are no longer obligated with respect
   to such liabilities, provided, however, that the foregoing shall not
   prohibit the Company or such Restricted Subsidiary from transferring assets
   in consideration of receipt of Additional Assets and other cash or Cash
   Equivalents; and

      (c) the Company delivers an Officers' Certificate to the Note Trustee
   certifying that such Asset Sale complies with the foregoing clauses (a) and
   (b).

   The Net Available Cash (or any portion thereof) from Asset Sales may be
applied by the Company or any Restricted Subsidiary, to the extent the Company
or any Restricted Subsidiary elects (or is required by the terms of any Debt):

      (a) to Repay Senior Debt of the Company or Debt of any Restricted
   Subsidiary (excluding, in any such case, any Debt owed to the Company or an
   Unregulated Affiliate of the Company); or

      (b) to reinvest in Additional Assets (including by means of an Investment
   in Additional Assets by such Restricted Subsidiary with Net Available Cash
   received by the Company or another Restricted Subsidiary).

   Any Net Available Cash from an Asset Sale not applied in accordance with the
preceding paragraph within one year from the date of the receipt of such Net
Available Cash or that is not segregated from the general funds of the Company
for investment in identified Additional Assets in respect of a project that
shall have been commenced, and for which binding contractual commitments have
been entered into, prior to the end of such one-year period and that shall not
have been completed or abandoned shall constitute "Excess Proceeds."

   When the aggregate amount of Excess Proceeds exceeds $25 million (taking
into account income earned on such Excess Proceeds, if any), the Company will
be required to make an offer to purchase (the "Prepayment Offer") the Notes,
which offer shall be in the amount of the Allocable Excess Proceeds, on a pro
rata basis according to the principal amount of the Notes, at a purchase price
equal to 100% of the principal amount thereof, plus accrued and unpaid
interest, if any, to the purchase date, in accordance with the procedures
(including prorating in the event of oversubscription) set forth in the
Indenture. To the extent that any portion of the amount of Net Available Cash
remains after compliance with the preceding sentence and provided that all
holders of Notes have been given the opportunity to tender their Notes for
purchase in accordance with the Indenture, the Company or any Restricted
Subsidiary may use such remaining amount for any purpose permitted by the
Indenture and the amount of Excess Proceeds will be reset to zero.

   The term "Allocable Excess Proceeds" will mean the product of:

      (a) the Excess Proceeds, and

      (b) a fraction,

          (1) the numerator of which is the aggregate principal amount of the
       Notes outstanding on the date of the Prepayment Offer, and

          (2) the denominator of which is the sum of the aggregate principal
       amount of the Notes outstanding on the date of the Prepayment Offer and
       the aggregate principal amount of other Debt of the Company outstanding
       on the date of the Prepayment Offer that is pari passu in right of
       payment with the Notes and subject to terms and conditions in respect of
       Asset Sales similar in all material

                                      35



       respects to the covenant described hereunder and requiring the Company
       to make an offer to purchase such Debt at substantially the same time as
       the Prepayment Offer.

   Within five business days after the Company is obligated to make a
Prepayment Offer as described in the second preceding paragraph, the Company
shall send a written notice, by first-class mail, to the holders of Notes,
accompanied by such information as the Company in good faith believes will
enable such holders to make an informed decision with respect to such
Prepayment Offer. Such notice shall state, among other things, the purchase
price and the purchase date, which shall be, subject to any contrary
requirements of applicable law, a business day no earlier than 30 days nor
later than 60 days from the date such notice is mailed.

   The Company will comply, to the extent applicable, with the requirements of
Section 14(e) of the Exchange Act and any other securities laws or regulations
in connection with the repurchase of Notes pursuant to the covenant described
hereunder. To the extent that the provisions of any securities laws or
regulations conflict with provisions of the covenant described hereunder, the
Company will comply with the applicable securities laws and regulations and
will not be deemed to have breached its obligations under the covenant
described hereunder by virtue thereof.

   Limitation on Restrictions on Distributions from any Restricted
Subsidiary.  The Company shall not, and shall not permit any Restricted
Subsidiary to, directly or indirectly, create or otherwise cause or suffer to
exist any consensual restriction on the right of such Restricted Subsidiary to:

      (a) pay dividends, in cash or otherwise, or make any other distributions
   on or in respect of its Capital Stock, or pay any Debt or other obligation
   owed, to the Company or any other Restricted Subsidiary;

      (b) make any loans or advances to the Company or any other Restricted
   Subsidiary; or

      (c) transfer any of its Property to the Company or any other Restricted
   Subsidiary.

   The foregoing limitations shall not apply:

      (1) to restrictions:

          (A) in effect on the Issue Date,

          (B) relating to Debt of any Restricted Subsidiary and existing at the
       time it became a Restricted Subsidiary, or

          (C) that result from the Refinancing of Debt Incurred pursuant to an
       agreement referred to in clause (1)(A) or (B) above or in clause (2)(A)
       or (B) below, provided that such restriction is no less favorable to the
       holders of Notes than those under the agreement evidencing the Debt so
       Refinanced, and

      (2) with respect to clause (c) only, to restrictions:

          (A) relating to Debt (that is permitted to be Incurred and secured
       without also securing the Notes) pursuant to the covenants described
       under "--Limitation on Debt" and "--Limitation on Liens" that limit the
       right of the debtor to dispose of the Property securing such Debt,

          (B) encumbering Property at the time such Property was acquired by
       the Company or any Restricted Subsidiary, so long as such restriction
       relates solely to the Property so acquired,

          (C) resulting from customary provisions restricting subletting or
       assignment of leases or customary provisions in other agreements that
       restrict assignment of such agreements or rights thereunder, or

          (D) customary restrictions contained in asset sale agreements
       limiting the transfer of such Property pending the closing of such sale.

                                      36



   Limitation on Transactions with Affiliates.  The Company shall not, and
shall not permit any Restricted Subsidiary to, directly or indirectly, conduct
any business or enter into or suffer to exist any transaction or series of
transactions (including the purchase, sale, transfer, assignment, lease,
conveyance or exchange of any Property or the rendering of any service) with,
or for the benefit of, any Affiliate of the Company (an "Affiliate
Transaction"), unless:

      (a) the terms of such Affiliate Transaction are:

          (1) set forth in writing, and

          (2) in the best interest of the Company or such Restricted
       Subsidiary, as the case may be, and

          (3) no less favorable to the Company or such Restricted Subsidiary,
       as the case may be, than those that could be obtained in a comparable
       arm's-length transaction with a Person that is not an Affiliate of the
       Company;

      (b) if such Affiliate Transaction involves aggregate payments or value in
   excess of $10 million, the Board of Directors approves such Affiliate
   Transaction and, in its good faith judgment, believes that such Affiliate
   Transaction complies with clauses (a)(2) and (a)(3) of this paragraph as
   evidenced by a Board resolution promptly delivered to the Note Trustee;

      (c) if such Affiliate Transaction involves aggregate payments or value in
   excess of $50 million, the Company obtains a written opinion from an
   Independent Financial Advisor to the effect that the consideration to be
   paid or received in connection with such Affiliate Transaction is fair, from
   a financial point of view, to the Company and such Restricted Subsidiary; or

      (d) if such Affiliate Transaction involves or arises out of contracts or
   agreements (1) in existence on the Issue Date and any amendments,
   modifications or extensions thereof not materially disadvantageous to the
   Company, or (2) ordered or required by the KCC.

   Limitation on Sale and Leaseback Transactions.  The Company shall not, and
shall not permit any Restricted Subsidiary to, enter into any Sale and
Leaseback Transaction with respect to any Property unless:

      (a) the Company or such Restricted Subsidiary would be entitled to:

          (1) Incur Debt in an amount equal to the Attributable Debt with
       respect to such Sale and Leaseback Transaction pursuant to the covenant
       described under "--Limitation on Debt," and

          (2) create a Lien on such Property securing such Attributable Debt
       without also securing the Notes pursuant to the covenant described under
       "--Limitation on Liens"; and

      (b) such Sale and Leaseback Transaction is effected in compliance with
   the covenant described under "--Limitation on Asset Sales".

   Designation of Restricted and Unrestricted Subsidiaries.  Subject to the
relevant provisions of the covenant described under "-- Limitation on Company's
Business," the Board of Directors may designate any Restricted Subsidiary
(including any newly acquired or newly formed Subsidiary of the Company), other
than KGE, to be an Unrestricted Subsidiary if such Subsidiary to be so
designated does not own any Capital Stock or Debt of, or own or hold any Lien
on any Property of, the Company or any other Restricted Subsidiary; provided
that: (A) any Guarantee by the Company or any Restricted Subsidiary of any Debt
of the Subsidiary being so designated shall be deemed an "Incurrence" of such
Debt and an "Investment" by the Company or such Restricted Subsidiary at the
time of such designation; (B) either the Subsidiary to be so designated has
total assets of $1,000 or less or if such Subsidiary has assets of greater than
$1,000, such designation would be permitted under "--Limitation on Restricted
Payments"; and (C) if applicable, the Incurrence of Indebtedness and the
Investment referred to in clause (A) of this covenant would be permitted under
"--Limitation on Debt" and "--Limitation on Restricted Payments."

   Unless so designated as an Unrestricted Subsidiary, any Person that becomes
a Subsidiary of the Company will be classified as a Restricted Subsidiary;
provided, however, that such Subsidiary shall not be designated a

                                      37



Restricted Subsidiary and shall be automatically classified as an Unrestricted
Subsidiary if either of the requirements set forth in clauses (x) and (y) of
the second immediately following paragraph will not be satisfied after giving
pro forma effect to such classification or if such Person is a Subsidiary of an
Unrestricted Subsidiary.

   In addition, neither the Company nor any Restricted Subsidiary shall be
directly or indirectly liable for any Debt incurred after the Issue Date that
provides that the holder thereof may (with the passage of time or notice or
both) declare a default thereon or cause the payment thereof to be accelerated
or payable prior to its Stated Maturity upon the occurrence of a default with
respect to any Debt, Lien or other obligation of any Unrestricted Subsidiary
(including any right to take enforcement action against such Unrestricted
Subsidiary).

   The Board of Directors may designate any Unrestricted Subsidiary to be a
Restricted Subsidiary if, immediately after giving pro forma effect to such
designation,

      (x) the Company could Incur at least $1.00 of additional Debt pursuant to
   clause (1) of the first paragraph of the covenant described under
   "--Limitation on Debt," and

      (y) no Default or Event of Default shall have occurred and be continuing
   or would result therefrom.

   Any such designation or redesignation by the Board of Directors will be
evidenced to the Note Trustee by filing with the Note Trustee a Board
Resolution giving effect to such designation or redesignation and an Officers'
Certificate that:

      (a) certifies that such designation or redesignation complies with the
   foregoing provisions, and

      (b) gives the effective date of such designation or redesignation,

such filing with the Note Trustee to occur within 45 days after the end of the
fiscal quarter of the Company in which such designation or redesignation is
made (or, in the case of a designation or redesignation made during the last
fiscal quarter of the Company's fiscal year, within 90 days after the end of
such fiscal year).

   Limitation on Company's Business.  The Company shall not, directly or
indirectly through Restricted Subsidiaries, engage primarily in any business
other than the Regulated Utility Business. For the avoidance of doubt, the
Company may not transfer any material portion of the assets used by the Company
in its Regulated Utility Business to any Affiliate and may not do so to any
Subsidiary unless (i) such Subsidiary is designated as a Restricted Subsidiary
and (ii) such Subsidiary unconditionally Guarantees the Company's obligations
under the Notes; provided, however, this covenant shall not limit the
businesses engaged in by the Unrestricted Subsidiaries or their Subsidiaries or
successors.

Merger, Consolidation and Sale of Property

   The Company shall not merge, consolidate or amalgamate with or into any
other Person (other than a merger of any Restricted Subsidiary into the
Company) or sell, transfer, assign, lease, convey or otherwise dispose of all
or substantially all its Property, excluding the Unrestricted Subsidiaries, in
any one transaction or series of transactions unless:

      (a) the Company shall be the surviving Person (the "Surviving Person") or
   the Surviving Person (if other than the Company) formed by such merger,
   consolidation or amalgamation or to which such sale, transfer, assignment,
   lease, conveyance or disposition is made shall be a corporation organized
   and existing under the laws of the United States of America, any State
   thereof or the District of Columbia and which is engaged primarily, directly
   or indirectly through Subsidiaries, in the Regulated Utility Business;

      (b) the Surviving Person (if other than the Company) expressly assumes,
   by supplemental indenture in form satisfactory to the Note Trustee, executed
   and delivered to the Note Trustee by such Surviving Person, the due and
   punctual payment of the principal of, and premium, if any, and interest on,
   all the Notes,

                                      38



   according to their tenor, and the due and punctual performance and
   observance of all the covenants and conditions of the Indenture to be
   performed by the Company;

      (c) in the case of a sale, transfer, assignment, lease, conveyance or
   other disposition of all or substantially all the Property of the Company,
   excluding the Unrestricted Subsidiaries, such Property shall have been
   transferred as an entirety or virtually as an entirety to one Person;

      (d) immediately before and after giving effect to such transaction or
   series of transactions on a pro forma basis (and treating, for purposes of
   this clause (d) and clauses (e) and (f) below, any Debt that becomes, or is
   anticipated to become, an obligation of the Surviving Person or a Restricted
   Subsidiary as a result of such transaction or series of transactions as
   having been Incurred by the Surviving Person or the Restricted Subsidiary at
   the time of such transaction or series of transactions), no Default or Event
   of Default shall have occurred and be continuing;

      (e) immediately after giving effect to such transaction or series of
   transactions on a pro forma basis, the Company or the Surviving Person, as
   the case may be, would be able to Incur at least $1.00 of additional Debt
   under clause (1) of the first paragraph of the covenant described under
   "--Limitation on Debt";

      (f) immediately after giving effect to such transaction or series of
   transactions on a pro forma basis, the Surviving Person shall have a
   Consolidated Net Worth in an amount which is not less than the Consolidated
   Net Worth of the Company immediately prior to such transaction or series of
   transactions; and

      (g) the Company shall deliver, or cause to be delivered, to the Note
   Trustee, in form and substance reasonably satisfactory to the Note Trustee,
   an Officers' Certificate and an Opinion of Counsel, each stating that such
   transaction and the supplemental indenture, if any, in respect thereto
   comply with this covenant and that all conditions precedent herein described
   relating to such transaction have been satisfied.

   The Surviving Person shall succeed to, and be substituted for, and may
exercise every right and power of the Company under the Indenture, but the
predecessor Company in the case of:

      (a) a sale, transfer, assignment, conveyance or other disposition (unless
   such sale, transfer, assignment, conveyance or other disposition is of all
   the assets of the Company as an entirety or virtually as an entirety), or
      (b) a lease,

shall not be released from any of the obligations or covenants under the
Indenture, including with respect to the payment of the Notes.

SEC Reports

   Notwithstanding that the Company may not be subject to the reporting
requirements of Section 13 or 15(d) of the Exchange Act, the Company shall file
with the SEC and provide the Note Trustee and holders of Notes with such annual
reports and such information, documents and other reports as are specified in
Sections 13 and 15(d) of the Exchange Act and applicable to a U.S. corporation
subject to such Sections, such information, documents and reports to be so
filed and provided at the times specified for the filing of such information,
documents and reports under such Sections; provided, however, that the Company
shall not be so obligated to file such information, documents and reports with
the SEC if the SEC does not permit such filings.

Events of Default

   Events of Default in respect of the Notes include:

      (a) failure to make the payment of any interest on the Notes when the
   same becomes due and payable, and such failure continues for a period of 30
   days;

                                      39



      (b) failure to make the payment of any principal of, or premium, if any,
   on, any of the Notes when the same becomes due and payable at its Stated
   Maturity, upon acceleration, redemption, optional redemption, required
   repurchase or otherwise;

      (c) failure to comply with the covenant described under "--Merger,
   Consolidation and Sale of Property";

      (d) failure to comply with any other covenant or agreement in the Notes
   or in the Indenture (other than a failure that is the subject of the
   foregoing clause (1), (2) or (3)) and such failure continues for 90 days
   after written notice is given to the Company as provided below;

      (e) a default under any Debt by the Company or any Restricted Subsidiary
   that results in acceleration of the maturity of such Debt, or failure to pay
   any such Debt at maturity, in an aggregate amount greater than $25 million
   (or its foreign currency equivalent at the time), which acceleration has not
   been rescinded or annulled within 10 days after the period for annulment in
   the agreement governing such Debt (the "cross acceleration provisions");

      (f) any judgment or judgments for the payment of money in an aggregate
   amount in excess of $25 million (or its foreign currency equivalent at the
   time) that shall be rendered against the Company or any Restricted
   Subsidiary and that shall not be waived, satisfied or discharged for any
   period of 60 consecutive days during which a stay of enforcement shall not
   be in effect (the "judgment default provisions"); and

      (g) certain events involving bankruptcy, insolvency or reorganization of
   the Company or any Restricted Subsidiary (the "bankruptcy provisions");

   A Default under clause (4) is not an Event of Default until the Note Trustee
or the holders of not less than 25% in aggregate principal amount of the Notes
then outstanding notify the Company of the Default and the Company does not
cure such Default within the time specified after receipt of such notice. Such
notice must specify the Default, demand that it be remedied and state that such
notice is a "Notice of Default."

   The Company shall provide an Officers' Certificate to the Note Trustee
promptly upon the Company obtaining knowledge of any Default or Event of
Default that has occurred, and, if applicable, describe such Default or Event
of Default, the status thereof and what action the Company is taking or
proposes to take with respect thereto.

   If an Event of Default with respect to the Notes (other than an Event of
Default resulting from certain events involving bankruptcy, insolvency or
reorganization with respect to the Company) shall have occurred and be
continuing, the Note Trustee or the registered holders of not less than 25% in
aggregate principal amount of the Notes then outstanding may declare to be
immediately due and payable the principal amount of all the Notes then
outstanding, plus accrued but unpaid interest to the date of acceleration. In
case an Event of Default resulting from certain events of bankruptcy,
insolvency or reorganization with respect to the Company shall occur, such
amount with respect to all the Notes shall be due and payable immediately
without any declaration or other act on the part of the Note Trustee or the
holders of the Notes. After any such acceleration, but efore a judgment or
decree based on acceleration is obtained by the Note Trustee, the registered
holders of a majority in aggregate principal amount of the Notes then
outstanding may, under certain circumstances, rescind and annul such
acceleration if all Events of Default, other than the nonpayment of accelerated
principal, premium or interest, have been cured or waived as provided in the
Indenture.

   Subject to the provisions of the Indenture relating to the duties of the
Note Trustee, in case an Event of Default shall occur and be continuing, the
Note Trustee shall be under no obligation to exercise any of its rights or
powers under the Indenture at the request or direction of any of the holders of
the Notes, unless such holders shall have offered to the Note Trustee indemnity
satisfactory to it. Subject to such provisions for the indemnification of the
Note Trustee, the holders of a majority in aggregate principal amount of the
Notes then

                                      40



outstanding shall have the right to direct the time, method and place of
conducting any proceeding for any remedy available to the Note Trustee or
exercising any trust or power conferred on the Note Trustee with respect to the
Notes.

   No holder of Notes shall have any right to institute any proceeding with
respect to the Indenture, or for the appointment of a receiver or trustee, or
for any remedy thereunder, unless:

      (a) such holder has previously given to the Note Trustee written notice
   of a continuing Event of Default,

      (b) the registered holders of at least 25% in aggregate principal amount
   of the Notes then outstanding have made written request and offered
   reasonable indemnity to the Note Trustee to institute such proceeding as
   trustee, and

      (c) the Note Trustee shall not have received from the registered holders
   of a majority in aggregate principal amount of the Notes then outstanding a
   direction inconsistent with such request and shall have failed to institute
   such proceeding within 60 days.

   However, such limitations do not apply to a suit instituted by a holder of
any Note for enforcement of payment of the principal of, and premium, if any,
or interest on, such Note on or after the respective due dates expressed in
such Note.

Amendments and Waivers

   Subject to certain exceptions, the Indenture may be amended with the consent
of the registered holders of a majority in aggregate principal amount of the
Notes then outstanding (including consents obtained in connection with a tender
offer or exchange offer for the Notes) and any past default or compliance with
any provisions may also be waived (except a default in the payment of
principal, premium or interest and certain covenants and provisions of the
Indenture which cannot be amended without the consent of each holder of an
outstanding Note) with the consent of the registered holders of at least a
majority in aggregate principal amount of the Notes then outstanding. However,
without the consent of each holder of an outstanding Note, no amendment may,
among other things,

      (1) reduce the amount of Notes whose holders must consent to an amendment
   or waiver,

      (2) reduce the rate of or extend the time for payment of interest on any
   Note,

      (3) reduce the principal of, or premium, if any, or extend the Stated
   Maturity of any Note,

      (4) make any Note payable in money other than U.S. dollars,

      (5) impair the right of any holder of the Notes to receive payment of
   principal of, or premium, if any, and interest on such holder's Notes on or
   after the due dates therefor or to institute suit for the enforcement of any
   payment on or with respect to such holder's Notes,

      (6) subordinate the Notes to any other obligation of the Company,

      (7) reduce the Change of Control Purchase Price or, at any time after a
   Change of Control has occurred, change the time at which the Change of
   Control Offer relating thereto must be made or at which the Notes must be
   repurchased pursuant to such Change of Control Offer, and

      (8) at any time after the Company is obligated to make a Prepayment Offer
   with the Excess Proceeds from Asset Sales, change the time at which such
   Prepayment Offer must be made or at which the Notes must be repurchased
   pursuant thereto.

   Without the consent of any holder of the Notes, the Company and the Note
Trustee may amend the Indenture to:

      (1) cure any ambiguity, omission, defect or inconsistency in any manner
   that is not adverse in any material respect to any holder of the Notes,

                                      41



      (2) provide for the assumption by a successor corporation of the
   obligations of the Company under the Indenture,

      (3) provide for uncertificated Notes in addition to or in place of
   certificated Notes,

      (4) secure the Notes, to add to the covenants of the Company for the
   benefit of the holders of the Notes or to surrender any right or power
   conferred upon the Company,

      (5) make any change that does not adversely affect the rights of any
   holder of the Notes,

      (6) make any change to the subordination provisions of the Indenture that
   would not limit or terminate the benefits available to any holder of Senior
   Debt under such provisions or to comply with any requirement of the SEC in
   connection with the qualification of the Indenture under the Trust Indenture
   Act of 1939, and

      (7) provide for the issuance of additional Notes in accordance with the
   Indenture.

   No amendment may be made to the subordination provisions of the Indenture
that adversely affects the rights of any holder of Senior Debt then outstanding
unless the holders of such Senior Debt (or their Representative) consent to
such change. The consent of the holders of the Notes is not necessary to
approve the particular form of any proposed amendment. It is sufficient if such
consent approves the substance of the proposed amendment. After an amendment
becomes effective, the Company is required to mail to each registered holder of
the Notes at such holder's address appearing in the security register a notice
briefly describing such amendment. However, the failure to give such notice to
all holders of the Notes, or any defect therein, will not impair or affect the
validity of the amendment.

Defeasance

   The Company at any time may terminate all its obligations under the Notes
and the Indenture ("legal defeasance"), except for certain obligations,
including those respecting the defeasance trust and obligations to register the
transfer or exchange of the Notes, to replace mutilated, destroyed, lost or
stolen Notes and to maintain a registrar and paying agent in respect of the
Notes.

   The Company at any time may terminate:

      (1) its obligations under the covenants described under "--Repurchase at
   the Option of Holders Upon a Change of Control" and "--Certain Covenants,"

      (2) the operation of the cross acceleration provisions, the judgment
   default provisions, and the bankruptcy provisions described under "--Events
   of Default" above, and

      (3) the limitations contained in clauses (e) and (f) under the first
   paragraph of "--Merger, Consolidation and Sale of Property," above
   ("covenant defeasance").

   The Company may exercise its legal defeasance option notwithstanding its
prior exercise of its covenant defeasance option.

   If the Company exercises its legal defeasance option, payment of the Notes
may not be accelerated because of an Event of Default with respect thereto. If
the Company exercises its covenant defeasance option, payment of the Notes may
not be accelerated because of an Event of Default specified in clause (4) (with
respect to the covenants described under "--Certain Covenants"), (5), (6) or
(7) under "--Events of Default" above or because of the failure of the Company
to comply with clauses (e) and (f) under the first paragraph of "--Merger,
Consolidation and Sale of Property," above.

   The legal defeasance option or the covenant defeasance option may be
exercised only if:

      (a) the Company irrevocably deposits in trust with the Note Trustee money
   or U.S. Government Obligations for the payment of principal of, premium, if
   any, and interest on the Notes to repurchase, redemption or maturity, as the
   case may be;

                                      42



      (b) the Company delivers to the Note Trustee a certificate from a
   nationally recognized firm of independent certified public accountants
   expressing their opinion that the payments of principal and interest when
   due and without reinvestment on the deposited U.S. Government Obligations
   plus any deposited money without investment will provide cash at such times
   and in such amounts as will be sufficient to pay principal, premium, if any,
   and interest when due on all the Notes to repurchase, redemption or
   maturity, as the case may be;

      (c) 91 days pass after the deposit is made and during the 91-day period
   no Default described in clause (7) under "--Events of Default" occurs with
   respect to the Company or any other Person making such deposit which is
   continuing at the end of the period;

      (d) no Default or Event of Default has occurred and is continuing on the
   date of such deposit and after giving effect thereto;

      (e) such deposit does not constitute a default under any other agreement
   or instrument binding on the Company;

      (f) in the case of the legal defeasance option, the Company delivers to
   the Note Trustee an Opinion of Counsel stating that:

          (1) the Company has received from the Internal Revenue Service, or
       "IRS," a ruling, or

          (2) since the date of the Indenture there has been a change in the
       applicable Federal income tax law, to the effect, in either case, that,
       and based thereon such Opinion of Counsel shall confirm that, the
       holders of the Notes will not recognize income, gain or loss for Federal
       income tax purposes as a result of such defeasance and will be subject
       to Federal income tax on the same amounts, in the same manner and at the
       same time as would have been the case if such legal defeasance had not
       occurred; and

      (g) in the case of the covenant defeasance option, the Company delivers
   to the Note Trustee an Opinion of Counsel to the effect that the holders of
   the Notes will not recognize income, gain or loss for Federal income tax
   purposes as a result of such covenant defeasance and will be subject to
   Federal income tax on the same amounts, in the same manner and at the same
   times as would have been the case if such legal defeasance had not occurred.

Governing Law

   The Indenture and the Notes are governed by the internal laws of the State
of New York without reference to principles of conflicts of law.

The Note Trustee

   Deutsche Bank Trust Company Americas is the Note Trustee under the Indenture.

   Except during the continuance of an Event of Default, the Note Trustee will
perform only such duties as are specifically set forth in the Indenture. During
the existence of an Event of Default, the Note Trustee will exercise such of
the rights and powers vested in it under the Indenture and use the same degree
of care and skill in its exercise as a prudent person would exercise under the
circumstances in the conduct of such person's own affairs.

Subsidiary which may properly be classified as current liabilities (including

   Subsidiary or between two or more Restricted Subsidiaries, and

      (b) all current maturities of long-term Debt.

      (a) the aggregate amount of EBITDA for the most recent four consecutive
   fiscal quarters for which financial statements are available prior to such
   determination date to

      (b) Consolidated Interest Expense for such four fiscal quarters;

          (A) since the beginning of such period the Company or any Restricted

       Debt, or

          (B) the transaction giving rise to the need to calculate the
       Consolidated Interest Coverage Ratio is an Incurrence or Repayment of
       Debt,

   Consolidated Interest Expense for such period shall be calculated after
giving effect on a pro forma basis to such Incurrence or Repayment as if such
Debt was Incurred or Repaid on the first day of such period, provided that, in
the event of any such Repayment of Debt, EBITDA for such period shall be
calculated as if the Company or any Restricted Subsidiary had not earned any

       all or substantially all of an operating unit of a business,

          (B) the transaction giving rise to the need to calculate the
       Consolidated Interest Coverage Ratio is such an Asset Sale, Investment
       or acquisition, or

                                      47



          (C) since the beginning of such period any Person (that subsequently
       became a Restricted Subsidiary or was merged with or into the Company or
       any Restricted Subsidiary since the beginning of such period) shall have
       made such an Asset Sale, Investment or acquisition,

then EBITDA for such period shall be calculated after giving pro forma effect
to such Asset Sale, Investment or acquisition as if such Asset Sale, Investment
or acquisition had occurred on the first day of such period.

   If any Debt bears a floating rate of interest and is being given pro forma
effect, the interest expense on such Debt shall be calculated as if the base
interest rate in effect for such floating rate of interest on the date of
determination had been the applicable base interest rate for the entire period
(taking into account any Interest Rate Agreement applicable to such Debt if
such Interest Rate Agreement has a remaining term in excess of 12 months). In
the event the Capital Stock of any Restricted Subsidiary is sold during the
period, the Company shall be deemed, for purposes of clause (1) above, to have
Repaid during such period the Debt of such Restricted Subsidiary to the extent
the Company and its continuing Restricted Subsidiary are no longer liable for
such Debt after such sale.

   "Consolidated Interest Expense" means, for any period, the total interest

   to letters of credit and bankers' acceptance financing,

      (f) net costs associated with Hedging Obligations (including amortization
   of fees),

      (g) Disqualified Stock Dividends and Preferred Stock Dividends (not
   including the dividends due in respect of the Preferred Stock of the Company
   or any Restricted Subsidiary outstanding as of the Issue Date),

      (h) interest Incurred in connection with Investments in discontinued
   operations,

      (i) interest accruing on any Debt of any other Person to the extent such
   Debt is Guaranteed by the Company or any Restricted Subsidiary, and

      (j) the cash contributions to any employee stock ownership plan or
   similar trust to the extent such contributions are used by such plan or
   trust to pay interest or fees to any Person (other than the Company) in
   connection with Debt Incurred by such plan or trust.

   "Consolidated Net Income" means, for any period, the net income (loss) of
the Company and any Restricted Subsidiary; provided, however, that there shall
not be included in such Consolidated Net Income:

      (a) any net income (loss) of any Person (other than the Company) if such
   Person is not a Restricted Subsidiary, except that, the Company's and any
   Restricted Subsidiary's interest in the net income of any such Person for

   shares, stock options or other rights to officers, directors and employees
   of the Company or any Restricted Subsidiary, provided that such shares,
   options or other rights can be redeemed at the option of the holder only for
   Capital Stock of the Company (other than Disqualified Stock).

   Notwithstanding the foregoing, for purposes of the covenant described under
"--Certain Covenants--Limitation on Restricted Payments" only, there shall be
excluded from Consolidated Net Income any dividends, repayments of loans or
advances or other transfers of Property from Unrestricted Subsidiaries to the
Company or any Restricted Subsidiary to the extent such dividends, repayments
or transfers increase the amount of Restricted Payments permitted under such

shall be considered to have been Repaid only to the extent the related loan
commitment, if any, shall have been permanently reduced in connection therewith.

no longer published, any publicly available source of similar market data))
most nearly equal to the period from the redemption date to May 1, 2007;
provided, however, that if the period from the redemption date to May 1, 2007
is less than one year, the weekly average yield on actively traded United
States Treasury securities adjusted to a constant maturity of one year shall be
used.

   "Unregulated Affiliate" means any Affiliate that is primarily engaged in a
business not involving the provision of utility services.

                                      59



   "Unrestricted Subsidiary" means:

                                      60



                               BOOK-ENTRY SYSTEM

   The outstanding securities are represented by a global security in
registered, global form without interest coupons (the " Outstanding Global
Security"). The Global Security was deposited upon issuance with the DTC or its
nominee, for credit to the accounts of persons holding through it with the
respective principal amounts of the outstanding securities represented by such
Global Security purchased by such persons in the offerings of the outstanding
securities.

   After the expiration of the exchange offers new global securities will be
issued. Those securities which are not exchanged will be represented by one or
more securities (the "Outstanding Global Security") in registered, global form
without interest coupons. The exchange securities will be represented by one or
more securities in registered, global form without interest coupons (the
"Exchange Global Securities" and together with the Outstanding Global
Securities, the "Global Securities"). The Global Securities will be deposited
on the date of the acceptance for exchange of the outstanding securities and
the issuance of the exchange securities with the DTC, and registered in the
name of a nominee of such depositary.

   Ownership of beneficial interests in the Global Securities will be limited
to persons that have accounts with DTC ("participants") or persons that may
hold interests through participants. Any person acquiring an interest in a
Global Securities through an offshore transaction in reliance on Regulation S
under the Securities Act ("Regulation S") may hold such interest through
Clearstream or Euroclear. Holders of exchange securities under DTC's system
must be made through direct participants who will receive a credit for the
Securities on DTC's records. The ownership interest of each beneficial owner is
in turn to be recorded on the records of the direct participants and indirect
participants. The laws of certain jurisdictions require that certain purchasers
of Securities take physical delivery of such exchange securities in definitive
form. Such limits and such laws may impair the ability to pledge or transfer
beneficial interests in the exchange securities.

   Payment of the principal of, or premium, if any, and interest on, exchange
securities represented by the Global Securities will be made in immediately
available funds to DTC or its nominee, as the case may be, as the sole
registered owner and the sole holder of the Securities represented thereby for
all purposes under the Mortgage or Indenture. We have been advised by DTC that
upon receipt of any payment of principal of, premium, if any, or interest on,
any Global Security, DTC will immediately credit, on its book-entry
registration and transfer system, the accounts of participants with payments in
amounts proportionate to their respective beneficial interests in such Global
Security as shown on the records of DTC. Payments by participants to owners of
beneficial interests in a Global Security held through such participants will
be governed by standing instructions and customary practices as is now the case
with securities held for customer accounts registered in "street name" and will
be the sole responsibility of such participants.

   A Global Security may not be transferred except as a whole by DTC or a
nominee of DTC to a nominee of DTC or to DTC. A Global Security is exchangeable
for certificated exchange securities only if:

      (a) DTC notifies us that it is unwilling or unable to continue as a
   depositary for such Global Security or if at any time DTC ceases to be a
   clearing agency registered under the Exchange Act;

      (b) we in our discretion at any time determine not to have all the
   exchange securities represented by such Global Security; or

      (c) there shall have occurred and be continuing a Default or an Event of
   Default with respect to the Securities represented by such Global Security.

   Any Global Security that is exchangeable for certificated exchange
securities pursuant to the preceding sentence will be exchanged for
certificated Securities in authorized denominations and registered in such
names as DTC or any successor depositary holding such Global Security may
direct. Subject to the foregoing, a Global Security is not exchangeable, except
for a Global Security of like denomination to be registered in the name of

                                      61



DTC or any successor depositary or its nominee. If a Global Security becomes
exchangeable for certificated Securities,

      (a) certificated exchange securities will be issued only in fully
   registered form in denominations of $1,000 or integral multiples thereof,

      (b) payment of the principal of, premium, if any, and interest on, the
   certificated exchange securities will be payable and the transfer of the
   certificated Securities will be registerable, at our office or an agency
   maintained by us for such purposes, and

      (c) no service charge will be made for any registration of the transfer
   or exchange of the certificated Securities, although we may require payment
   of a sum sufficient to cover any tax or governmental charge imposed in
   connection therewith.

   So long as DTC or any successor depositary for a Global Security, or any
nominee, is the registered owner of such Global Security, DTC or such successor
depositary or nominee, as the case may be, will be considered the sole owner or
holder of the Securities represented by such Global Security for all purposes
under the Mortgage, the Indenture and the Securities. Except as set forth
above, owners of beneficial interests in a Global Security will not be entitled
to have the Securities represented by such Global Security registered in their
names, will not receive or be entitled to receive physical delivery of
certificated Securities in definitive form and will not be considered to be the
owners or holders of any exchange securities under such Global Security.
Accordingly, each person owning a beneficial interest in a Global Security must
rely on the procedures of DTC or any successor depositary, and, if such person
is not a participant, on the procedures of the participant through which such
person owns its interest, to exercise any rights of a holder under the Mortgage
or the Indenture. We understand that under existing industry practices, in the
event that we request any action of holders or that an owner of a beneficial
interest in a Global Security desires to give or take any action which a holder
is entitled to give or take under the Mortgage or the Indenture, DTC or any
successor depositary would authorize the participants holding the relevant
beneficial interest to give or take such action, and such participants would
authorize beneficial owners owning through such participants to give or take
such action or would otherwise act upon the instructions of beneficial owners
owning through them.

   DTC has advised us that DTC is a limited-purpose trust company organized
under the Banking Law of the State of New York, a member of the Federal Reserve
System, a "clearing corporation" within the meaning of the New York Uniform
Commercial Code and a "clearing agency" registered under the Exchange Act. DTC
was created to hold the securities of its participants and to facilitate the
clearance and settlement of securities transactions among its participants in
such securities through electronic book-entry changes in their respective
accounts, thereby eliminating the need for physical movement of securities
certificates. DTC's participants include securities brokers and dealers (which
may include the initial purchasers), banks, trust companies, clearing
corporations and certain other organizations, some of which (or their
representatives) own DTC. Access to DTC's book-entry system is also available
to others, such as banks, brokers, dealers and trust companies, that clear
through or maintain a custodial relationship with a participant, either
directly or indirectly.

   Although DTC has agreed to the foregoing procedures in order to facilitate
transfers of interests in Global Securities among participants of DTC, it is
under no obligation to perform or continue to perform such procedures, and such
procedures may be discontinued at any time.

                                      62



                CERTAIN U.S. FEDERAL INCOME TAX CONSIDERATIONS

   The following discussion is a summary of certain U.S. Federal income tax
considerations relevant to the purchase, ownership and disposition of the
securities by the holders thereof. This summary does not purport to be a
complete analysis of all the potential U.S. Federal income tax consequences
relating to the ownership and disposition of the exchange securities by holders
who acquired the exchange securities in the exchange offers. There can be no
assurance that the IRS will take a similar view of such consequences. Further,
the discussion does not address all aspects of taxation that may be relevant to
particular purchasers in light of their individual circumstances (including the
effect of any foreign, state or local laws) or to certain types of purchasers
subject to special treatment under U.S. Federal income tax laws (including
dealers in securities, insurance companies, financial institutions,
pass-through entities, persons that hold securities that are a hedge or that
are hedged against currency risks or that are part of a straddle or conversion
transaction, persons whose functional currency is not the U.S. dollar and
tax-exempt entities). The discussion below assumes that the exchange securities
are held as capital assets and were acquired at original issue for their
original "issue price."

   The discussion of the U.S. Federal income tax consequences below is based on
currently existing provisions of the Code, judicial decisions, and
administrative interpretations. Because individual circumstances may differ,
each holder of outstanding securities, is strongly urged to consult its own tax
advisor with respect to its particular tax situation and the particular tax
effects of any state, local, non-U.S. or other tax laws and possible changes in
the tax laws. As used herein, the term "U.S. Holder" means a beneficial owner
of a Bond or a Note who or which is for U.S. Federal income tax purposes either:

      (a) a citizen or resident of the U.S.;

      (b) a corporation or other entity treated as a corporation, created or
   organized in or under the laws of the U.S. or of any political subdivision
   thereof;

      (c) an estate the income of which is subject to U.S. Federal income
   taxation regardless of its source; or

      (d) a trust if a court within the U.S. is able to exercise primary
   supervision over the administration of the trust and one or more U.S.
   persons have the authority to control all substantial decisions of the trust.

   The term "U.S. Holder" also includes certain former citizens of the U.S.
whose income and gain on the Securities will be subject to U.S. taxation. As
used herein, the term "Non-U.S. Holder" means a beneficial owner of a Bond or a
Note that is not a U.S. Holder or a pass-through entity.

   The exchange of the outstanding securities for exchange securities will not
be a taxable event for federal income tax purposes. A holder will not recognize
any taxable gain or loss as a result of exchanging outstanding securities for
exchange securities, and the holder will have the same tax basis and holding
period in the exchange securities as he had in the outstanding securities
immediately before exchange.

Tax Consequences to U.S. Holders

Payments of Interest

   Interest on an exchange bond or exchange note generally will be taxable to a
U.S. Holder as ordinary income at the time it accrues or is received, in
accordance with the U.S. Holder's method of accounting for U.S. Federal income
tax purposes.

   If special interest is paid, although not free from doubt, such payment
should be taxable to a U.S. Holder as ordinary income at the time it accrues or
is received in accordance with such U.S. Holder's regular method of accounting.
It is possible, however, that the IRS may take a different position, in which
case the timing and amount of income inclusion may be different.

                                      63



   Under certain circumstances, we may be entitled to redeem all or a portion
of the exchange bonds and/or the exchange notes. In addition, under certain
circumstances, each holder of the exchange bonds or the exchange notes, as the
case may be, will have the right to require us to repurchase all or any part of
such holder's exchange bonds or exchange notes. Treasury Regulations contain
special rules for determining the yield to maturity or maturity date of a debt
instrument in the event the debt instrument provides for a contingency that
could result in the acceleration or deferral of one or more payments. We do not
believe that these rules are likely to apply either to our right to redeem the
exchange bonds and/or the exchange notes or to the holders' rights to require
us to repurchase the exchange bonds and/or the exchange notes. Therefore, we do
not intend to treat such redemption and repurchase provisions of the exchange
bonds and/or exchange notes as affecting the computation of the yield to
maturity or maturity date of the exchange bonds and/or exchange notes.

Sale, Exchange or Retirement of Securities

   Upon the sale, exchange or retirement of an exchange bond or an exchange
note, a U.S. Holder will recognize taxable gain or loss equal to the difference
between the amount realized on the sale, exchange or retirement (not including
any amount attributable to accrued but unpaid interest) and such U.S. Holder's
adjusted tax basis in the exchange bond or the exchange note, as the case may
be. A U.S. Holder's adjusted tax basis in an exchange bond or an exchange note
generally will be equal to the cost of the Bond or Note to such U.S. Holder.

   In general, gain or loss realized on the sale, exchange or retirement of an
exchange bond or an exchange note by a U.S. Holder will be capital gain or
loss, and will be long-term capital gain or loss if at the time of the sale,
exchange or retirement, the U.S. Holder has held the exchange bond or exchange
note for more than one year. For a U.S. Holder who is an individual, long-term
capital gain generally is taxed at a Federal maximum rate of 20%. The
distinction between capital gain or loss and ordinary income or loss is also
relevant for purposes of, among other things, limitations on the deductibility
of capital losses.

Tax Consequences to Non-U.S. Holders

   Under present U.S. Federal income tax law, and subject to the discussion
below concerning backup withholding:

      1.  payments of the principal of, premium, if any, or interest on, the
   exchange securities by us or any paying agent to a beneficial owner of the
   Securities that is a Non-U.S. Holder will not be subject to U.S. Federal
   withholding tax, or the "portfolio interest exemption," provided that, in
   the case of interest:

          (a) such Non-U.S. Holder does not own, actually or constructively,
       10% or more of the total combined voting power of all classes of our
       stock;

          (b) such Non-U.S. Holder is not, for U.S. Federal income tax
       purposes, a controlled foreign corporation related, directly or
       indirectly, to us through stock ownership;

          (c) such Non-U.S. Holder is not a bank receiving interest described
       in Section 881(c)(3)(A) of the Code; and

          (d) the certification requirements under Section 871(h) or Section
       881(c) of the Code and Treasury Regulations thereunder (summarized
       below) are met.

      2.  a Non-U.S. Holder of the exchange securities will not be subject to
   U.S. Federal income tax on gains realized on the sale, exchange or other
   disposition of such exchange securities, unless:

          (a) such holder is an individual who is present in the U.S. for 183
       days or more in the taxable year of sale, exchange or other disposition,
       and certain other conditions are met;

          (b) such gain is effectively connected with the conduct by such
       Non-U.S. Holder of a trade or business in the U.S., and if so provided
       in an applicable tax treaty, is attributable to a U.S. permanent
       establishment maintained by the Non-U.S. Holder; or

                                      64



          (c) the Non-U.S. Holder is subject to tax pursuant to the Code
       provisions applicable to certain U.S. expatriates.

   Sections 871(h) and 881(c) of the Code and currently effective Treasury
Regulations thereunder require that, to obtain the exemption from withholding
tax described above, either (a) the beneficial owner of an exchange bond or an
exchange note must certify on IRS Form W-8BEN, under penalties of perjury, to
us or the paying agent, as the case may be, that such owner is a Non-U.S.
Holder and must provide such owner's name and address, and U.S. taxpayer
identification number, if any, or (b) a securities clearing organization, bank
or other financial institution that holds customers' securities in the ordinary
course of its trade or business, or a "financial institution" that holds the
exchange bond or the exchange note on behalf of the beneficial owner thereof
must certify, under penalties of perjury, to us or the paying agent, as the
case may be, that such certificate has been received from the beneficial owner
by it or by a financial institution between it and the beneficial owner and
must furnish the payor with a copy thereof.

   If a Non-U.S. Holder of an exchange bond or an exchange note is engaged in a
trade or business in the U.S., and if interest on such exchange bond or
exchange note, or gain realized on the sale, exchange or other disposition of
such exchange bond or exchange note, is effectively connected with the conduct
of such trade or business and, if so provided in an applicable tax treaty, is
attributable to a U.S. permanent establishment maintained by the Non-U.S.
Holder, the Non-U.S. Holder, although exempt from U.S. withholding tax, will
generally be subject to regular U.S. income tax on such interest or gain in the
same manner as if it were a U.S. Holder. In lieu of the certificate described
in the preceding paragraph, such a holder must provide us a properly executed
IRS Form W-8ECI to claim an exemption from withholding tax. In addition, if
such Non-U.S. Holder is a foreign corporation, it may be subject to a branch
profits tax equal to 30% (or such lower rate provided by an applicable treaty)
of its effectively connected earnings and profits for the taxable year, subject
to certain adjustments. For purposes of the branch profits tax, interest on and
any gain recognized on the sale, exchange or other disposition of an exchange
bond or an exchange note is included in the earnings and profits of the
Non-U.S. Holder if such interest or gain is effectively connected with the
conduct by the Non-U.S. Holder of a trade or business in the U.S.

   Interest that neither qualifies for the portfolio interest exemption
described above nor constitutes U.S. trade or business income will be subject
to U.S. withholding tax at the rate of 30% unless such withholding tax is
reduced or eliminated by an applicable income tax treaty. To claim the
protection of an income tax treaty, a Non-U.S. Holder must provide a properly
executed Form W-8BEN prior to the payment of interest and must periodically
update such Form W-8BEN (or, if necessary, provide the applicable successor
form). A Non-U.S. Holder may be required to obtain a U.S. taxpayer
identification number and provide documentary evidence issued by foreign
governmental authorities to prove residence in a foreign treaty country.

Information Reporting and Backup Withholding

   We will, where required, report to the holders of the exchange bonds and/or
exchange notes and the IRS the amount of any interest paid on the exchange
bonds and/or exchange notes in each calendar year and the amounts of Federal
income tax withheld, if any, with respect to payments. A noncorporate U.S.
Holder may be subject to information reporting and to backup withholding with
respect to payments of principal, premium, if any, and interest made on the
exchange bonds and/or the exchange notes, or on proceeds of the disposition of
the exchange bonds and/or exchange notes before maturity, unless such U.S.
Holder provides a correct taxpayer identification number or proof of an
applicable exemption, and otherwise complies with applicable requirements of
the information and backup withholding rules. The backup withholding rate for
payments made in 2002 and 2003 is 30% and will be reduced to 29% for years 2004
and 2005, and further reduced to 28% for years 2006 through 2007.

   Backup withholding and information reporting will not apply to payments made
by us or any agent thereof (in its capacity as such) to a Non-U.S. Holder of
the exchange securities if such Non-U.S. Holder has provided

                                      65



the required certification that it is not a U.S. person on the Form W-8BEN or
has otherwise established an exemption (provided that neither we nor our agents
have actual knowledge or has reason to know that such holder is a U.S. person
or that the conditions of any exemption are not in fact satisfied).

   Payments of the proceeds from the sale of exchange securities to or through
a foreign office of a broker will not be subject to information reporting or
backup withholding, except if the broker is (i) a U.S. person, (ii) a
controlled foreign corporation, (iii) a foreign person 50% or more of whose
gross income for certain periods is effectively connected with a U.S. trade or
business, or (iv) a foreign partnership, if at any time during its taxable year
one or more of its partners are U.S. persons who in the aggregate hold more
than 50% of the income or capital interest in the partnership, or if at any
time during its taxable year the foreign partnership is engaged in a U.S. trade
or business, unless the Non-U.S. Holder establishes an exception.

   Backup withholding is not an additional tax. Any amount withheld under the
backup withholding rules will be refunded or credited against the Non-U.S.
Holder's Federal income tax liability, provided that the required information
is furnished to the IRS.

   THE FOREGOING DISCUSSION IS FOR GENERAL INFORMATION ONLY AND IS NOT TAX
ADVICE. ACCORDINGLY, EACH PROSPECTIVE HOLDER OF A BOND OR NOTE SHOULD CONSULT
ITS OWN TAX ADVISOR AS TO THE PARTICULAR TAX CONSEQUENCES TO THE PROSPECTIVE
HOLDER OF PURCHASING, HOLDING AND DISPOSING OF THE BONDS AND/OR NOTES,
INCLUDING THE APPLICABILITY AND EFFECT OF ANY STATE, LOCAL OR NON-U.S. INCOME
TAX LAWS AND ANY RECENT OR PROSPECTIVE CHANGES IN APPLICABLE TAX LAWS.

                             PLAN OF DISTRIBUTION

   Each broker-dealer that receives exchange securities for its own account
pursuant to the exchange offer must acknowledge that it will deliver a
prospectus in connection with any resale of such exchange securities. This
prospectus, as it may be amended or supplemented from time to time, may be used
by a broker-dealer in connection with resales of exchange securities received
in exchange for outstanding securities where such outstanding securities were
acquired by such broker-dealer as a result of market-making activities or other
trading activities. We have agreed that, starting on the expiration date and
ending on the close of business one year after the expiration date, we will
make this prospectus, as amended or supplemented, available to any
broker-dealer for use in connection with any such resale. In addition,
until      , 200 ,  all dealers effecting transactions in the exchange
securities may be required to deliver a prospectus.

   We will not receive any proceeds from any sale of exchange securities by
broker-dealers. Exchange securities received by broker-dealers for their own
account pursuant to the exchange offer may be sold from time to time in one or
more transactions in the over-the-counter market, in negotiated transactions,
through the writing of options on the exchange securities or a combination of
such methods of resale, at market prices prevailing at the time of resale, at
prices related to such prevailing market prices or at negotiated prices. Any
such resale may be made directly to purchasers or to or through brokers or
dealers who may receive compensation in the form of commissions or concessions
from any such broker-dealer and/or the purchasers of any such exchange
securities. Any broker-dealer that resells exchange securities that were
received by it for its own account pursuant to the exchange offer and any
broker or dealer that participates in a distribution of such exchange
securities may be deemed to be an "underwriter" within the meaning of the
Securities Act and any profit of any such resale of exchange securities and any
commissions or concessions received by any such persons may be deemed to be
underwriting compensation under the Securities Act. The letter of transmittal
states that, by acknowledging that it will deliver and by delivering a
prospectus, a broker-dealer will not be deemed to admit that it is an
"underwriter" within the meaning of the Securities Act.

   For a period of one year after the expiration date, we will promptly send
additional copies of this prospectus and any amendment or supplement thereto to
any broker-dealer that requests such documents in the letter of transmittal. We
have agreed to pay all expenses incident to the exchange offer (including the
expenses of any one counsel for the Holders of the Notes) other than
commissions or concessions of any brokers or dealers and will indemnify the
Holders of the Notes participating in the exchange offer (including any
broker-dealers) against certain liabilities, including liabilities under the
Securities Act.

                                 LEGAL MATTERS

   Legal matters as to the validity of the exchange securities offered by this
prospectus will be passed upon for the company Larry D. Irick, Esq., our Vice
President and Corporate Secretary, as to matters governed by Kansas law.

                            INDEPENDENT ACCOUNTANTS

   Our consolidated financial statements and the related financial statement
schedule, as of December 31, 2001 and 2000, and for each of the years in the
three-year period ended December 31, 2001, included in our 2001 Form 10-K, have
been audited by Arthur Andersen LLP, independent certified public accountants,
as stated in their report, incorporated by reference herein in reliance upon
the authority of that firm as experts in giving such reports. We have not been
able to obtain, after reasonable efforts, the written consent of Arthur
Andersen to the inclusion of their report in this prospectus, and we have
dispensed with the requirement to file their consent in reliance on Rule 437A
promulgated under the Securities Act. Because Arthur Andersen has not consented
to the inclusion of its report in this prospectus, your ability to assert
claims against Arthur Andersen may be limited. In particular, because of this
lack of consent, you will not be able to sue Arthur Andersen under Section
11(a)(4) of the Securities Act for any untrue statements of a material fact
contained in the financial statements audited by Arthur Andersen or any
omissions to state a material fact required to be stated in those financial
statements and therefore your right of recovery under that section may be
limited.

                  INFORMATION NOT REQUIRED IN THE PROSPECTUS

ITEM 20.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.

   Article XVIII of the registrant's Restated Articles of Incorporation, as
amended, provides that a director shall not be personally liable to the
corporation or its stockholders for monetary damages for breach of fiduciary
duty as a director except for liability (i) for any breach of the director's
duty of loyalty to the corporation or its stockholders, (ii) for acts or
omissions not in good faith or which involve intentional misconduct or a
knowing violation of law, (iii) for paying a dividend or approving a stock
repurchase in violation of the Kansas General Corporation Law or (iv) for any
transaction from which the director derived an improper personal benefit. This
provision is specifically authorized by Section 17-6002(b)(8) of the Kansas
General Corporation Law.

   Section 17-6305 of the Kansas General Corporation Law (the "Indemnification
Statute") provides for indemnification by a corporation of its corporate
officers, directors, employees and agents. The indemnification Statute provides
that a corporation may indemnify such persons who have been, are, or may become
a party to an action, suit or proceeding due to his or her status as a
director, officer, employee or agent of the corporation. Further, the
Indemnification Statute grants authority to a corporation to implement its own
broader indemnification policy. Article XVIII of the registrant's Restated
Articles of Incorporation, as amended, requires the corporation to indemnify
its directors and officers to the fullest extent provided by Kansas law.
Further, as is provided for in Article XVIII, the registrant entered into
indemnification agreements with its directors, which provide indemnification
broader than that available under Article XVIII and the Indemnification Statute.

ITEM 22.  UNDERTAKINGS.

   The undersigned Registrants hereby undertake that:

      (a) For purposes of determining any liability under the Securities Act of
   1933, each filing of the registrant's annual report pursuant to section
   13(a) or section 15(d) of the Securities Exchange Act of 1934 that is
   incorporated by reference in this registration statement shall be deemed to
   be a new registration statement relating to the securities offered therein,
   and the offering of such securities at that time shall be deemed to be the
   initial bona fide offering thereof.

      (b) To deliver or cause to be delivered with the prospectus, to each
   person to whom the prospectus is sent or given, the latest annual report to
   security holders that is incorporated by reference in the prospectus and
   furnished pursuant to and meeting the requirements of Rule 14a-3 or Rule
   14c-3 under the Securities Exchange Act of 1934; and, where interim
   financial information required to be presented by Article 3 of Regulation
   S-X are not set forth in the prospectus, to deliver, or cause to be
   delivered to each person to whom the prospectus is sent or given, the latest
   quarterly report that is specifically incorporated by reference in the
   prospectus to provide such interim financial information.

      (c) Insofar as indemnification for liabilities arising under the
   Securities Act of 1933 may be permitted to directors, officers and
   controlling persons of the registrant pursuant to the foregoing provisions,
   or otherwise, the registrant has been advised that in the opinion of the
   Securities and Exchange Commission such indemnification is against public
   policy as expressed in the Securities Act and is, therefore, unenforceable.
   In the event that a claim for indemnification against such liabilities
   (other than the payment by the registrant of expenses incurred or paid by a
   director, officer or controlling person of the registrant in the successful
   defense of any action, suit or proceeding) is asserted by such director,
   officer or controlling person in connection with the securities being
   registered, the registrant will, unless in the opinion of its counsel the
   matter has been settled by controlling precedent, submit to a court of
   appropriate jurisdiction the question whether such indemnification by it is
   against public policy as expressed in the Act and will be governed by the
   final adjudication of such issue.

      (d) To respond to requests for information that is incorporated by
   reference into the prospectus pursuant to Item 4, 10(b), 11 or 13 of this
   Form, within one business day of receipt of such request, and to send the
   incorporated documents by first class mail or other equally prompt means.
   This undertaking includes information contained in documents filed
   subsequent to the effective date of this registration statement through the
   date of responding to the request.

      (e) To supply by means of a post-effective amendment all information
   concerning a transaction and the company being acquired involved therein,
   that was not the subject of and included in this registration statement when
   it became effective.

                                     II-4



                                  SIGNATURES

   Pursuant to the requirements of the Securities Act of 1933, the Registrant
has duly caused this Registration Statement to be signed on its behalf by the
undersigned, thereunto duly authorized in the City of Topeka, State of Kansas,
on the 26th day of June, 2002.
