including the documents incorporated in this Prospectus by reference. As used
in this Prospectus, the term "Western Resources" refers to Western Resources,
Inc. and, unless the context otherwise requires, its subsidiaries, and the term
"KCPL" refers to Kansas City Power & Light Company and, unless the context
otherwise requires, its subsidiaries.
 
WESTERN RESOURCES
 
  Western Resources, and its wholly owned subsidiaries, include KPL, a rate-

KCPL
 
  The following information concerning KCPL is derived from the KCPL 1995 Form
10-K:
 
  KCPL was incorporated in 1922 under the laws of Missouri and is a public
utility engaged in the generation, transmission, distribution and sale of
electricity to approximately 430,000 customers in western Missouri and eastern
Kansas. KLT Inc., a wholly owned unregulated subsidiary of KCPL, pursues
opportunities in domestic and international energy-related ventures. KCPL also
owns 47% of WCNOC. KCPL has its principal executive offices at 1201 Walnut
Street, Kansas City, Missouri 64106-2124.
 
BACKGROUND OF THE OFFER
 
  Prior Communications with KCPL. KCPL and Western Resources have discussed the
possibility of a merger at various times over the last two years. In June 1994,
KCPL and Western Resources exchanged confidential information in connection
with preliminary discussions regarding a possible business combination. KCPL
declined Western Resources' request to present its analysis of the benefits of
a merger between the two companies, and the confidential information was
returned in August 1994. Discussions and correspondence between Mr. A. Drue
Jennings, Chairman of the Board, President, and Chief Executive Officer of
KCPL, and Mr. John E. Hayes, Jr., Chairman of the Board and Chief Executive
Officer of Western Resources, relating to a potential merger continued over the
next several months.
 
  In February 1995, Mr. Hayes expressed Western Resources' interest in a
combination with KCPL and the synergies and substantial benefits of such a
combination. In March 1995, Mr. Jennings wrote to Mr. Hayes that KCPL had
decided to focus on its current business plan rather than a business
combination with Western
 
                                       1
<PAGE>
 
Resources. In May 1995, Mr. Hayes sent a letter to Mr. Jennings again proposing
a merger of the two companies. Mr. Hayes also requested that KCPL outline its
interest, requirements or suggestions regarding a combination. In a letter, Mr.
Hayes stressed that Western Resources strongly preferred a negotiated
transaction with KCPL.
 
  On December 14, 1995, Mr. Hayes sent letters to each of Mr. Jennings and Mr.
Richard C. Green, Jr., Chairman of the Board and Chief Executive Officer of
UtiliCorp United Inc. ("UtiliCorp"), stating that Western Resources believed
that KCPL and UtiliCorp were in discussions concerning a possible combination
and requesting an opportunity to meet with Mr. Jennings and Mr. Green regarding
a possible combination.
 
  On the day of announcement of the merger of each of UtiliCorp and KCPL with
and into KC United Corp. (the "Proposed UtiliCorp/KCPL Transaction"), Mr.
Jennings telephoned Mr. Hayes to inform him of this development. Mr. Hayes
offered to meet with Mr. Jennings and discuss the possibility of a combination
with Western Resources but such offer was declined by Mr. Jennings.
 
  KCPL entered into the Agreement and Plan of Merger, dated as of January 19,
1996, by and among UtiliCorp, KCPL and KC United Corp. (the "UtiliCorp/KCPL
Merger Agreement") despite the fact that, as of January 19, 1996, KCPL was
aware of Western Resources' continuing interest to pursue a combination with
KCPL. See "Background of the Offer--The UtiliCorp /KCPL Merger Agreement."
 
  The April 14 Offer and Related Actions. On April 14, 1996, Mr. Hayes
telephoned Mr. Jennings to inform him that he was having delivered to Mr.
Jennings that afternoon a written proposal to the KCPL board of directors to
acquire all of the outstanding Shares in a transaction in which each holder of
Shares ("KCPL Shareholders") would be entitled to receive for each Share a
number of shares of Western Resources Common Stock equal to the Exchange Ratio
(as defined herein) (the "April 14 Offer").
 
  Following such telephone conversation Western Resources delivered to Mr.
Jennings a letter setting forth such offer which, among other things and taking
into account the April 12, 1996 closing (the last trading day before public
announcement of the April 14 Offer) stock prices and Western Resources $2.06
current annual dividend, represents a 17% premium and an indicated annual
dividend rate of $1.98 per Share, which is 27% higher than the current
indicated annual dividend rate in respect of the Shares. The letter also
pointed out that a combination with Western Resources would produce over $1
billion in savings during the ten years following consummation of the merger.
On April 15, 1996, Western Resources filed an Application with the State
Corporation Commission of the State of Kansas (the "KCC") seeking approval of
such combination and a Petition to Intervene in the Proposed UtiliCorp/KCPL
Transaction. See "Background of the Offer--The April 14 Offer and Related
Actions."
 
  On April 22, 1996, Mr. Jennings had delivered to Mr. Hayes a letter stating
that the KCPL board of directors had rejected the April 14 Offer. After the
delivery of the letter, Mr. Jennings telephoned Mr. Hayes to inform him of the
decision of the KCPL board of directors.
 
  On April 22, 1996, Western Resources announced its intention to commence the
Offer. As part of such announcement, Western Resources also stated that it had
filed a Proxy Statement with the Commission for use in soliciting proxies from
KCPL Shareholders against the approval and adoption of the UtiliCorp/KCPL
Merger Agreement and the Proposed UtiliCorp/KCPL Transaction.

COMPARISON OF THE PROPOSALS
 
  Offer Premium and Dividend Impact. Western Resources believes that the Offer
is clearly financially superior to the Proposed UtiliCorp/KCPL Transaction. The
annual dividend rate for each Share and the closing price per Share on April
12, 1996 (the last trading day before public announcement of the April 14
Offer) were $1.56 and $23.875, respectively. For the twenty trading days
immediately preceding April 12, 1996, the average closing price per share was
$24.956. The Offer provides a substantial premium to KCPL Shareholders in
relation to those levels, as shown by the following table:

  In addition, as shown by the following table, the Offer provides greater

UtiliCorp/KCPL Transaction assuming no change to the existing KCPL dividend
policy.

** Based on the current annual dividend rate of $2.06 per share of Western
   Resources Common Stock and the closing price of Western Resources Common
   Stock on the indicated dates. The implied annual dividend rate per Share
   will vary depending on the price of Western Resources' common stock at the
   time the Exchange Ratio is finally determined. Based on Western Resources'
   current annual dividend rate of $2.06 per share, the indicated annual
   dividend rate per Share would range from a minimum of $1.72 to a maximum of
   $2.03, or from 10% to 30% more than KCPL's current annual dividend.
 
  The premium and dividend accretion to KCPL Shareholders may change as the
market price of Western Resources Common Stock changes.
 
  For more detailed information concerning the background of the Offer, and for
a comparison of the Offer and the Proposed UtiliCorp/KCPL Transaction, see
"Background of the Offer" and "Background of the Offer--Comparison of the
Proposals" below.
 
  Potential Cost Savings. Western Resources believes that the KCPL
Shareholders, as well as KCPL's customers, employees and the communities it
serves, would realize benefits from the Offer and the Merger that are greater
than the benefits that would be realized if KCPL either remains an independent
entity or completes the Proposed UtiliCorp/KCPL Transaction. Western Resources
believes such greater benefit would be realized through the operational and
structural synergies as more fully set forth under "Background of the Offer--
Comparison of the Proposals--Potential Cost Savings." Anticipated net cost
savings from the Offer and the Merger are expected to exceed $1 billion
compared to approximately $636 million (derived from the KC United Registration
Statement and the KCPL/UtiliCorp Joint Application, Docket No. 194-141-U, filed
with the KCC on February 2, 1996 (the "KCPL/UtiliCorp Joint Application") for
the Proposed UtiliCorp/KCPL Transaction over a ten-year period.
 
  Regulatory Approvals. Regulatory commissions reviewing the Offer and the
Proposed UtiliCorp/KCPL Transaction will be asked to take into account the
greater customer benefits of the Offer when deciding between
 
                                       3
<PAGE>
 
the applications for approval. As such, Western Resources believes that it will
be able to obtain the necessary regulatory approvals for the Offer on a timely
basis and in a time frame at least as favorable as that in which UtiliCorp
would be able to obtain the necessary regulatory approvals for the Proposed
UtiliCorp/KCPL Transaction. With the cooperation of KCPL, Western Resources
believes that the Offer and the Merger could be completed by the second quarter
of 1997, otherwise Western Resources believes the Offer and the Merger could be
completed by year-end 1997. In light of the superior benefits and savings of
the Offer, Western Resources does not believe the Proposed UtiliCorp/KCPL
Transaction could be completed prior to year-end 1997. Accordingly, Western
Resources believes that the Proposed UtiliCorp/KCPL Transaction offers no
timing advantage over the Offer. (See "Background of the Offer--Comparison of
the Proposals--Regulatory Approvals").
 
  The UtiliCorp/KCPL Merger Agreement. On January 19, 1996, UtiliCorp and KCPL
entered into the UtiliCorp/KCPL Merger Agreement. The UtiliCorp/KCPL Merger
Agreement provides that, if approved by the shareholders of KCPL and UtiliCorp
and the satisfaction or waiver of certain other conditions, including obtaining
the requisite regulatory approvals, KCPL and UtiliCorp would be merged with and
into KC United Corp. ("KC United"), with KC United being the surviving
corporation. The Proposed UtiliCorp/KCPL Transaction is subject to certain
conditions customary in transactions in the utility industry, including among
others that all regulatory and shareholder approvals be obtained. The
UtiliCorp/KCPL Merger Agreement also includes the payment of a termination fee
of up to $58 million in certain circumstances. For a more detailed description
of the UtiliCorp/KCPL Merger Agreement, see "Background of the Offer--The
UtiliCorp/KCPL Merger Agreement."
 
THE OFFER
 
  General. Western Resources hereby offers, upon the terms and subject to the
conditions set forth herein and in the related Letter of Transmittal
(collectively, the "Offer"), to exchange shares of Western Resources Common
Stock, for each outstanding Share, validly tendered on or prior to the
Expiration Date and not withdrawn. Each Share validly tendered on or prior to
the Expiration Date and not withdrawn will be entitled to receive that number
of shares of Western Resources Common Stock equal to the Exchange Ratio. The
term "Exchange Ratio" means the quotient (rounded to the nearest 1/100,000)
determined by dividing $28.00 by the average of the high and low sales prices
of Western Resources Common Stock (as reported on the New York Stock Exchange
(the "NYSE") Composite Transactions reporting system as published in The Wall
Street Journal or, if not published therein, in another authoritative source)
on each of the twenty consecutive trading days ending with the second trading
day immediately preceding the Expiration Date; provided, that the Exchange
Ratio shall not be less than 0.833 nor greater than 0.985. See "The Offer--
General." The term "Expiration Date" shall mean 12:00 Midnight, New York City
Time, on        , 1996 unless the Offer is extended.
 
  The purpose of the Offer is to obtain control of, and ultimately exchange the
entire common equity interest in, KCPL. Western Resources intends, as soon as
practicable after consummation of the Offer, to seek to merge KCPL with and
into itself pursuant to section 351.447 of the Missouri General and Business
Corporation Law (the "MGBCL") and Section 17-6703 of the Kansas General
Corporation Code (the "KGCC"). Under Section 351.447 and section 17-6703,
assuming the Minimum Tender Condition, the Western Resources Shareholder
Approval Condition, the Missouri Control Share Acquisition Condition, the
Missouri Business Combination Condition and KCPL Preferred Stock Redemption
Condition are satisfied, Western Resources could merge KCPL into itself (the
"Merger") without any vote of the shareholders of either Western Resources or
KCPL. Pursuant to the Merger, each outstanding Share (except for Shares held in
the treasury of KCPL and Shares held by shareholders who properly exercise
their dissenters' rights, if any, under Missouri law) would be converted into
the right to receive a number of shares of Western Resources Common Stock equal
to the Exchange Ratio. See "The Offer--Purpose of the Offer; the Merger;" "The
Offer--Dissenters' Rights."
 
  Western Resources' obligation to exchange shares of Western Resources Common
Stock for Shares pursuant to the Offer is conditioned upon, among other things,
satisfaction or waiver, as applicable, of the Minimum Tender Condition, the
Western Resources Shareholder Approval Condition, the Missouri Control
 
                                       4
<PAGE>
 
Share Acquisition Condition, the Missouri Business Combination Condition, the
UtiliCorp/KCPL Merger Agreement Condition, the Regulatory Approval Condition,
the Pooling Condition, the Short Form Merger Condition, the KCPL Preferred
Stock Redemption Condition (in each case as defined on the cover page of this
Prospectus) and the other conditions set forth in "The Offer--Conditions of the
Offer--Certain Other Conditions of the Offer" (collectively, the "Offer
Conditions"). See "The Offer--Conditions of the Offer--Minimum Tender
Condition," "--Western Resources Shareholder Approval Condition," "--Missouri
Control Share Acquisition Condition," "--Missouri Business Combination
Condition," "--The UtiliCorp/KCPL Merger Agreement Condition," "--Regulatory
Approval Condition," "--Pooling Condition," "--Short Form Merger Condition,"
"--KCPL Preferred Stock Redemption Condition" and "--Certain Other Conditions
of the Offer." Waiver or amendment of any of these conditions may require an
extension of the Offer.
 
  Timing of the Offer. The Offer is currently scheduled to expire on      ,
1996. See "The Offer--Extension, Termination and Amendment." Consummation of
the Offer and the Merger is subject to numerous regulatory approvals. For a
discussion of the timing of such regulatory approvals, see "The Offer--
Regulatory Approval Condition." KCPL Shareholders are scheduled to vote on the
UtiliCorp/KCPL Merger Agreement at the KCPL annual meeting to be held on May
22, 1996. If the KCPL Shareholders do not approve the UtiliCorp/KCPL Merger
Agreement or the KCPL board of directors terminates the UtiliCorp/KCPL Merger
Agreement, the UtiliCorp/KCPL Merger Agreement Condition will then be
satisfied. Western Resources believes that the KCPL board of directors should
at that point respect the vote of the KCPL Shareholders and take all necessary
action in accordance with their fiduciary duties to allow the Offer and the
Merger to proceed.
 
  Extension, Termination and Amendment. Western Resources expressly reserves
the right (but will not be obligated), in its sole discretion, at any time or
from time to time, and regardless of whether any of the events set forth in
"The Offer--Conditions of the Offer" shall have occurred or shall have been
determined by Western Resources to have occurred, (a) to extend the period of
time during which the Offer is open by giving oral or written notice of such
extension to the Exchange Agent, which extension must be announced no later
than 9:00 A.M., New York City time, on the next business day after the
previously scheduled Expiration Date, and (b) to amend the Offer in any respect
(including, without limitation, by decreasing or increasing the consideration
offered in the Offer to holders of Shares and/or by decreasing the number of
Shares being sought in the Offer) by giving oral or written notice of such
amendment to the Exchange Agent. The rights reserved by Western Resources in
this paragraph are in addition to Western Resources' rights to terminate the
Offer as described in "The Offer--Extension, Termination and Amendment." There
can be no assurance that Western Resources will exercise its right to extend
the Offer. However, it is Western Resources' current intention to extend the
Offer until all conditions have been satisfied or waived. See "The Offer--
Extension, Termination and Amendment." During any such extension, all Shares
previously tendered and not withdrawn will remain subject to the Offer, subject
to the right of a tendering shareholder to withdraw his Shares. See "The
Offer--Withdrawal Rights."
 
  Exchange of Shares; Delivery of Western Resources Common Stock. Upon the
terms and subject to the conditions of the Offer, the acceptance for exchange
and the exchange of all outstanding Shares validly tendered and not properly
withdrawn will be made as soon as practicable after the Expiration Date. See
"The Offer--Exchange of Shares; Delivery of Western Resources Common Stock."
 
  Withdrawal Rights. Tenders of Shares made pursuant to the Offer are
irrevocable, except that Shares tendered pursuant to the Offer may be withdrawn
at any time prior to the Expiration Date, and, unless theretofore accepted for
exchange and paid for by Western Resources pursuant to the Offer, may also be
withdrawn at any time after      , 1996. See "The Offer--Withdrawal Rights."
 
  Procedure for Tendering Shares. For a shareholder validly to tender Shares
pursuant to the Offer, (i) a properly completed and duly executed Letter of
Transmittal (or facsimile thereof), together with any required signature
guarantees, or an Agent's Message (as defined herein) in connection with a
book-entry transfer, and any other required documents, must be transmitted to
and received by the Exchange Agent at one of its addresses set forth on the
back cover of this Prospectus and either certificates for tendered Shares must
be received by the
 
                                       5
<PAGE>
 
Exchange Agent at such address or such Shares must be tendered pursuant to the
procedures for book-entry tender set forth under "The Offer--Procedure for
Tendering" (and a confirmation of receipt of such tender received), in each
case, prior to the Expiration Date, or (ii) such shareholder must comply with
the guaranteed delivery procedure set forth under "The Offer--Procedure for
Tendering."
 
  THE METHOD OF DELIVERY OF SHARE CERTIFICATES AND ALL OTHER REQUIRED
DOCUMENTS, INCLUDING DELIVERY THROUGH ANY BOOK-ENTRY TRANSFER FACILITY, IS AT
THE OPTION AND RISK OF THE TENDERING SHAREHOLDER, AND THE DELIVERY WILL BE
DEEMED MADE ONLY WHEN ACTUALLY RECEIVED BY THE EXCHANGE AGENT. IF DELIVERY IS
BY MAIL, REGISTERED MAIL WITH RETURN RECEIPT REQUESTED, PROPERLY INSURED, IS
RECOMMENDED. IN ALL CASES, SUFFICIENT TIME SHOULD BE ALLOWED TO ENSURE TIMELY
DELIVERY.
 
  Certain Federal Income Tax Consequences In the opinions of Sullivan &
Cromwell and LeBoeuf, Lamb, Greene & MacRae, L.L.P., special counsel to Western
Resources, exchanges of Shares for Western Resources Common Stock pursuant to
the Offer and the Merger should be treated for federal income tax purposes as
exchanges pursuant to a plan of reorganization within the meaning of the
Internal Revenue Code of 1986, as amended (the "Code"). Consequently, if the
Offer and the Merger qualify as a reorganization, no gain or loss will be
recognized by holders of Shares upon such exchanges, except with respect to the
receipt of cash in lieu of fractional shares of Western Resources Common Stock.
This opinion is based on Sullivan & Cromwell's and LeBoeuf, Lamb, Greene &
MacRae, L.L.P.'s views that the Offer and the Merger should be treated as a
single transaction and on certain assumptions, including that (a) the
continuity of shareholder interest requirement applicable to corporate
reorganizations (which requires a continuing equity interest in Western
Resources by holders owning a significant percentage of the Shares prior to the
consummation of the Offer) will be satisfied, taking into account any holders
that exercise dissenters' rights, if any, (b) Western Resources will continue
KCPL's historic business or will use a significant portion of KCPL's historic
business assets in a business, and (c) the Offer and the Merger will generally
be consummated as contemplated by this Prospectus. Although there are currently
no binding agreements that would ensure that the shareholders of KCPL will have
a continuing equity interest in Western Resources following the consummation of
the Offer and the Merger, Western Resources believes that it is likely that the
shareholders of KCPL will retain a sufficient amount of the stock of Western
Resources to satisfy the continuity of interest requirement.
 
  Assuming that the Merger qualifies as a reorganization under the Code, no
gain or loss will be recognized by Western Resources or KCPL as a result of the
Offer and the Merger. If the Offer and the Merger together qualify as a
reorganization within the meaning of Section 368(a)(1)(A) of the Code, no gain
or loss will be recognized by a U.S. Holder (as defined under "The Offer--
Certain Federal Income Tax Consequences"), except with respect to a U.S. Holder
who receives cash in lieu of fractional shares of Western Resources Common
Stock.
 
  If the Merger is not consummated, or if the Merger is consummated but the
Offer is treated as a separate transaction for federal income tax purposes, the
Offer may fail to meet all of the requirements of a tax-free reorganization and
exchanges pursuant to the Offer may therefore be taxable transactions for
federal income tax purposes. In that case, each U.S. Holder exchanging Shares
for shares of Western Resources Common Stock pursuant to the Offer will
recognize gain or loss for federal income tax purposes measured by the
difference between such U.S. Holder's adjusted basis in the Shares exchanged
and the sum of the fair market value of Western Resources Common Stock received
by such U.S. Holder pursuant to the Offer and any cash received by such U.S.
Holder in lieu of fractional shares of Western Resources Common Stock.
 
                                       6
<PAGE>
 
 
  If the Offer is a taxable transaction, the Merger itself would be a
reorganization within the meaning of Section 368(a)(1)(A) of the Code if the
continuity of interest requirement is satisfied in the Merger. For advance
ruling purposes, guidelines published by the Internal Revenue Service would
require that KCPL Shareholders receive in the Merger stock of Western Resources
having a value equal to at least 50% of the value of all of the stock of KCPL
outstanding prior to the Merger. If the Offer is treated as a separate
transaction for federal income tax purposes, however, Western Resources Common
Stock issued in the Offer should count towards establishing that the Merger
satisfies the continuity of interest requirement. If the continuity of interest
requirement is satisfied in the Merger, a U.S. Holder receiving Western
Resources Common Stock in the Merger would be subject to the rules concerning
reorganizations described above with respect to such Western Resources Common
Stock, but not with respect to any Western Resources Common Stock received by
such U.S. Holder pursuant to the Offer.
 
  All Shareholders should carefully read the discussion of the material federal
income tax consequences of the Offer under "The Offer--Certain Federal Income
Tax Consequences" and are urged to consult with their own tax advisors as to
the federal, state, local and foreign tax consequences in their particular
circumstances.
 
  Effect of Offer on Market for Shares; Registration Under the Exchange
Act. The exchange of Shares pursuant to the Offer will reduce the number of
holders of Shares and the number of Shares that might otherwise trade publicly
and, depending upon the number of Shares so purchased, could adversely affect
the liquidity and market value of the remaining Shares held by the public.
 
  The Shares are listed and principally traded on the NYSE and are also listed
on the CSE. Depending on the number of Shares acquired pursuant to the Offer,
following consummation of the Offer, the Shares may no longer meet the
requirements of such exchanges for continued listing and the Shares may no
longer constitute "margin securities" for the purposes of the Federal Reserve
Board's margin regulations, in which event the Shares would be ineligible as
collateral for margin loans made by brokers. For a description of the treatment
of Shares in the Merger, see "The Offer--Purpose of the Offer; the Merger."
 
  Dissenters' Rights. In connection with the Merger and pursuant to Sections
351.447 and 351.455 of the MGBCL, a KCPL Shareholder may, by following the
procedures set forth in "The Offer--Dissenters' Rights," demand that Western
Resources pay the fair value of his Shares. Within ten days after the effective
date of the Merger, Western Resources will notify each holder of Shares still
outstanding immediately after consummation of the Offer that the Merger has
occurred. A dissenting shareholder then has twenty days after the mailing of
such notice to demand in writing the fair value of his Shares immediately prior
to the Merger, exclusive of any element of value arising from the expectation
or accomplishment of the Merger. For a more detailed description, see "The
Offer--Purpose of the Offer; the Merger" and "The Offer--Dissenters' Rights."

SELECTED UNAUDITED FORECASTED FINANCIAL DATA
 
  The forecast was prepared to reflect the pro forma results of operations for
the pre-Merger periods of 1996 and 1997 and the combined company post-Merger
results from operations for the periods 1998 through 2000. For purposes of the
forecast, the Merger is assumed to be consummated on January 1, 1998 and to be
accounted for as a pooling of interests.
 
  The forecast was developed solely by Western Resources from the stand-alone
forecast of Western Resources and, for KCPL, a forecast based on public
information, analysts' forecasts, knowledge of cost trends associated with
generating units jointly owned by Western Resources and KCPL, and Western
Resources' knowledge of the electric utility industry. To the best knowledge
and belief of Western Resources, the assumptions contained within the forecast
are reasonable. The assumptions disclosed herein are those which Western
Resources believes are significant to the forecast.
 
  This forecasted financial information involves significant judgments and
assumptions which may not be realized and are inherently subject to significant
uncertainties, all of which are difficult to predict and many of which are
beyond the control of Western Resources. Accordingly, there can be no assurance
this forecast will be realized and actual results may vary materially from
those shown. Selected significant assumptions to the forecasted financial data
are described in the "Summary of Selected Significant Assumptions" below and in
further detail in "Unaudited Forecasted Financial Data."

                  SUMMARY OF SELECTED SIGNIFICANT ASSUMPTIONS
                                  (UNAUDITED)
 
 . Increases in dividends are assumed to be continued consistent with Western
  Resources' past practice.
 
 . The major modifications which are assumed to result from the Merger include
  the estimated net cost savings and the proposed Regulatory Plan.
 
 . The assumptions incorporate forecasts of sales and revenues for Western
  Resources' gas operations and KCPL and Western Resources' electric
  operations.
 
 . The forecast assumes that increases in Western Resources' purchased gas costs
  will continue to be recovered through appropriate adjustment mechanisms
  within its rate structures.
 
 . The forecast assumes annual compound rates of growth in electric and gas
  operations and maintenance costs of approximately 3% before estimated cost
  savings and excluding scheduled refueling of Wolf Creek, medical costs and
  specific lease costs.
 
 . The assumptions associated with depreciation are consistent with each
  company's current practices with the exception of the adjustments made to
  reflect the proposed Regulatory Plan.
 
 . Income and other taxes are forecasted to increase or decrease as a direct
  result of changes in revenues, capital additions and wage rates. Income taxes
  were computed using the combined statutory income tax rates and the
  appropriate "flow through" items for each company in accordance with current
  and assumed regulatory treatment.
 
 . The financing requirements included in the forecasts were developed from cash
  requirements resulting from anticipated capital expenditures, refunding
  requirements and the results of operations as adjusted for the Merger.
 
  See "Unaudited Forecasted Financial Data" and "Notes to Unaudited Forecasted
Statement of Income" for an expanded discussion of selected significant
assumptions used in the forecast.

                            BACKGROUND OF THE OFFER
 
PRIOR COMMUNICATIONS WITH KCPL
 
  KCPL and Western Resources have discussed the possibility of a merger at
various times over the last two years. In June 1994, KCPL and Western
Resources exchanged confidential information in connection with preliminary
discussions regarding a possible business combination. KCPL declined Western
Resources' request to present its analysis of the benefits of a merger between
the two companies and the confidential information was returned in August
1994. Discussions and correspondence between Mr. Jennings and Mr. Hayes
relating to a potential merger continued over the next several months.
 
  In February 1995, Mr. Hayes expressed Western Resources' interest in a
combination with KCPL and the synergies and substantial benefits of such a
combination. In March 1995, Mr. Jennings wrote to Mr. Hayes that KCPL had
decided to focus on its current business plan rather than a business
combination with Western Resources. In May 1995, Mr. Hayes sent a letter to
Mr. Jennings again proposing a merger of the two companies. Mr. Hayes also
requested that KCPL outline its interest, requirements or suggestions
regarding a combination. In a letter, Mr. Hayes stressed that Western
Resources strongly preferred a negotiated transaction with KCPL.
 
  On December 14, 1995, Mr. Hayes sent letters to each of Mr. Jennings and Mr.
Green stating that Western Resources believed that KCPL and UtiliCorp were in
discussions concerning a possible combination and requesting an opportunity to
meet with Mr. Jennings and Mr. Green regarding a possible combination.
 
  On the day of announcement of the Proposed UtiliCorp/KCPL Transaction, Mr.
Jennings telephoned Mr. Hayes to inform him of this development. Mr. Hayes
offered to meet with Mr. Jennings and discuss the possibility of a combination
with Western Resources, but such offer was declined by Mr. Jennings.
 
  KCPL entered into the UtiliCorp/KCPL Merger Agreement despite the fact that,
as of January 19, 1996, KCPL was aware of Western Resources' continuing
interest to pursue a combination with KCPL. See "--The UtiliCorp/KCPL Merger
Agreement."
 
THE APRIL 14 OFFER AND RELATED ACTIONS
 
  On April 14, 1996, Mr. Hayes telephoned Mr. Jennings to inform him that he
was having delivered to Mr. Jennings that afternoon a written proposal to the
KCPL board of directors to acquire all of the outstanding Shares in a
transaction in which each KCPL Shareholder would be entitled to receive for
each Share a number of shares of Western Resources Common Stock equal to the
Exchange Ratio.
 
  Following such telephone conversation Western Resources delivered to Mr.
Jennings the following letter:
 
                                                                 April 14, 1996
 
Mr. Drue Jennings
Chairman of the Board, President & Chief Executive Officer
Kansas City Power & Light Company
1201 Walnut Street
Kansas City, Missouri 64141
 
Dear Drue,
 
  Following the filing of the proxy and regulatory application for your
proposed transaction with UtiliCorp, we have undertaken a further detailed
review of the benefits from a combination of Western Resources and KCPL and
have compared those benefits to those that would result from the proposed
UtiliCorp/KCPL combination. The difference in the proposals is striking and
demonstrates that a combination of our companies will result in significant
benefits for each company's respective shareholders, customers and employees.
 
                                      15
<PAGE>
 
  Accordingly, the Western Resources Board of Directors has authorized the
submission of the following merger proposal: KCPL and Western Resources would
merge in a transaction in which each KCPL common shareholder will receive $28
worth of Western Resources common stock in exchange for each KCPL share. The
exchange ratio is subject to a collar so that KCPL shareholders will receive
no less than .833 and no more than .985 shares of Western Resources common
stock for each share of KCPL common stock.
 
  Based upon last Friday's closing stock prices and Western Resources' $2.06
current annual dividend, our proposal represents a 17% premium above KCPL's
market price and a dividend rate of $1.98 per KCPL share, which is 27% higher
than KCPL's current dividend rate.
 
  Some of the other major benefits of our proposal include:
 
  . More than $1 billion in aggregate cost savings during the first 10 years
   following completion of the merger, which is 64% greater than in your
   proposed merger with UtiliCorp. Our savings are greater due to the larger
   size of our business as contrasted to UtiliCorp ($5.5 billion in assets
   versus $3.9 billion), our overlapping service territory and the $2.0
   billion of plant under common ownership.
 
  . Earnings accretion for KCPL and Western Resources' shareholders.
 
  . An initial rate reduction of $21 million and cumulative rate reductions
    of $210 million for KCPL's retail electric customers in the first 10
    years following the merger. This is a 30% greater reduction in rates than
    in the proposed UtiliCorp/KCPL transaction.
 
  . An initial rate reduction of $10 million and a cumulative rate reduction
    of $100 million for KGE's retail electric customers in the first ten
    years following the merger, in addition to our current rate reduction
    plan.
 
  . A five-year moratorium on electric rate increases for KCPL, KPL and KGE
    retail customers.
 
  . No layoffs of any KCPL or Western Resources' employees.
 
  . A stronger financial partner in Western Resources' A- bond rating as
    compared to UtiliCorp's BBB rating.
 
  We have a history of delivering on our promises. When we merged with KGE, we
provided $32 million in customer rebates and delivered all of the projected
cost savings. This was accomplished without employee layoffs. We are confident
we can deliver to our constituents again.
 
  Subject to your Board's favorable response to our proposal, we are prepared
to negotiate a merger agreement on substantially the same terms and conditions
as your proposed merger with UtiliCorp, including its tax-free structure,
except that (i) we would expect the Board of Western Resources, after the
merger, to be composed of nine directors from KCPL and 13 from Western
Resources, and (ii) the headquarters of KCPL would remain in Kansas City,
Missouri, the headquarters of KGE would remain in Wichita, and the
headquarters of KPL and Western Resources would remain in Topeka. In addition,
we are prepared to offer you the same position on the same terms following a
merger with us as you would have had with your proposed UtiliCorp/KCPL merger.
We also believe we offer your senior management opportunities for continued
career growth that appear to us not to exist with UtiliCorp.
 
  The combined company will be in a better position to promote economic and
civic development for the greater Kansas City area. The level of charitable
giving in the greater Kansas City area from both Western Resources and KCPL
will remain no less than the present combined involvement for at least the
next five years. Additionally, we will commit to locate one of our rapidly
growing business units in Kansas City, which will bring hundreds of jobs and
national and international business opportunities to Kansas City. Most
importantly, we will be able to reduce prices to both KCPL and KGE customers
to 10% below the national average, making our customers and their businesses
more competitive.
 
                                      16
<PAGE>
 
  The two companies together will be better positioned to lead the reshaping
of the increasingly competitive marketplace brought about by technology, and
customer and legislative demands. We will be able to create value because of
our larger competitive scale, expanded access to future energy customers and
the complementary nature of our growing energy businesses. As examples, the
Wing Group and KLT Energy will blend both domestic and international power
development businesses and our consumer energy services business aligned with
your deployment of new technologies will expand our capabilities to offer
innovative services.
 
  Our offer is, of course, contingent upon all necessary approvals from
shareholders, regulatory and other governmental agencies, and the availability
of pooling of interest accounting. In addition, this offer is expressly
conditioned on KCPL's compliance with its obligations under the Agreement and
Plan of Merger, dated as of January 19, 1996 between UtiliCorp and KCPL,
including but not limited to Sections 7.11 and 9.1 thereof.
 
  We are filing tomorrow an Application with the Kansas Corporation Commission
seeking approval of our proposed Western Resources/KCPL merger and a Petition
to Intervene in the proposed UtiliCorp/KCPL matter, Docket No. 194,141-U. This
filing provides additional detail regarding the comparative benefits of our
proposal and points out that the public interest requires that the KCC
consider competing alternatives when deciding whether to approve the proposed
UtiliCorp/KCPL merger. Likewise, we expect to file shortly with the Missouri
Public Service Commission.
 
  We appreciate that you will want to present our proposal to your Board of
Directors for its careful consideration. We feel that after such
consideration, your Board will agree with us that our proposal is financially
superior to the proposed transaction with UtiliCorp. We are also prepared to
meet with you or with you and your directors to discuss our proposal and to
answer any questions you or they may have.
 
  Drue, as I am sure you can appreciate with a proposal of this sort, time is
of the essence. Accordingly, we would appreciate hearing from you as soon as
practicable, and in any event, no later than 12:00 noon on Monday, April 22,
1996.
 
                                         Sincerely,
 
                                         /s/ John
 
  Shortly after delivery of the letter, Western Resources made a public
announcement regarding the delivery of the April 14 Offer and released the
letter to the Dow Jones News Service and certain other media outlets.
 
  On April 22, 1996, Mr. Jennings had delivered to Mr. Hayes a letter stating
that the KCPL board of directors had rejected the April 14 Offer. After the
delivery of the letter, Mr. Jennings telephoned Mr. Hayes to inform him of the
decision of the KCPL board of directors.
 
                                      17

  On April 22, 1996, Western Resources announced its intention to commence the
Offer. As part of such announcement, Western Resources also stated that it had
filed a Proxy Statement with the Commission for use in soliciting proxies from
KCPL Shareholders against the approval and adoption of the UtiliCorp/KCPL
Merger Agreement and the Proposed UtiliCorp/KCPL Transaction (the "Proxy
Solicitation").
 
 
COMPARISON OF THE PROPOSALS
 
  Offer Premium and Dividend Impact. Western Resources believes that the Offer
is clearly financially superior to the Proposed UtiliCorp/KCPL Transaction.
The indicated annual dividend rate for KCPL and the closing price per Share on
April 12, 1996 (the last trading day before public announcement of the April
14 Offer) were $1.56 and $23.875, respectively. For the twenty trading days
immediately preceding April 12, 1996, the average closing price per Share was
$24.956. The Offer provides a substantial premium to KCPL Shareholders in
relation to those levels, as shown by the following table:

   $1.72 to a maximum of $2.03, or from 10% to 30% more than KCPL's current
   annual dividend.
 
  The premium and dividend accretion to KCPL Shareholders may change as the
market price of Western Resources Common Stock changes.
 
  Potential Cost Savings. Western Resources believes that the KCPL
Shareholders, as well as KCPL's customers, employees and the communities it
serves, would realize benefits from the Offer and the Merger that are greater
than the benefits that would be realized if KCPL either remains an independent
entity or completes
 
                                      18
<PAGE>
 
the Proposed UtiliCorp/KCPL Transaction. Western Resources believes such
greater benefits would be realized through the following operational and
structural synergies:
 
  . Operational coordination--The geographic locations of the respective
    service territories of Western Resources and KCPL, which both operate in
    eastern Kansas and whose headquarters are within 60 miles of one another,
    provide an opportunity to efficiently integrate all aspects of their
    utility operations. Western Resources, along with KGE, already has
    numerous substantial electrical interconnections with KCPL. The combined
    system would be expected to benefit because it, unlike a combined
    UtiliCorp/KCPL system, could be operated as part of a single, larger
    cohesive system, with virtually no modification needed with respect to
    existing generating and transmission facilities. At present, Western
    Resources and KCPL maintain joint ownership in, or Western Resources is
    the lessee in, an operating lease with a third party of approximately
    2,440 mw of generation capacity that is operated by either WCNOC or KCPL
    and accounts for more than $2 billion in assets.
 
  . Complementary businesses--Western Resources operates a natural gas
    distribution business segment that adds substantial value to the combined
    company because of the partial co-location of this business with KCPL's
    electric operations. The nonregulated businesses of Western Resources and
    KCPL, such as independent power development, also complement each other.
    The combined customer bases of Western Resources and KCPL will provide
    more opportunities for earnings growth from other consumer service-
    oriented businesses.
 
  . A stronger company and a more diverse service territory--The combined
    company would be stronger than a combination of UtiliCorp and KCPL or
    Western Resources or KCPL as independent entities. The larger size of a
    Western Resources/KCPL combination and the financial strength of Western
    Resources' A- credit rating compared with UtiliCorp's BBB rating would
    enhance the combined company's flexibility to deal with new industry
    developments. In addition, the combined company's service territory would
    be more diverse than the service territory of either Western Resources or
    KCPL as independent entities. Such size and diversity improve the mix of
    commercial, industrial, agricultural and residential customers and reduce
    the exposure to changes in economic or climatic conditions in any given
    segment of the combined service territory.
 
  . Integrated product and service portfolio--The integration of the gas and
    electric business segments would enable the combined company to enhance
    the portfolio of products and services available to customers. This
    integration of products and services would position Western Resources and
    KCPL as providers of comprehensive energy solutions.
 
  . Economic development opportunities--The combined company would be able to
    concentrate its economic development programs and activities rather than
    pursue parallel paths with respect to potential customers or industry
    groups, which would enhance the ability of the combined company to
    attract to or retain within Kansas and Missouri such potential customers
    or industry groups.
 
  Western Resources believes that available synergies should generate cost
savings in excess of $1 billion to the combined company over a ten-year
period. The major components of the anticipated cost savings are as follows:
 
  Generation
 
  . Integration of dispatching and production operations--The combined
    company could obtain fuel savings from joint dispatch of generating
    capacity that is not available when the two companies are operated as two
    separate systems. Fuel savings result from an improved ability to
    schedule and commit each of the base load, intermediate and peaking
    facilities of the combined company in a more economically efficient
    manner.
 
  . Avoidance or deferral of future capital expenditures--The combined
    company would have the ability to reduce future expenditures for
    generating capacity by coordinating and optimizing planning for future
 
                                      19
<PAGE>
 
   resources. The combination of the two companies would result in system
   diversity due to differences in the timing of peak demands. This system
   makes available amounts of generating capacity which result in the delay
   or elimination of additional capacity now planned by the two stand-alone
   companies. The delay or elimination of these additional facilities also
   reduces the operations and maintenance expense associated with the total
   combined generation capacity.
 
  . Integration of generation and technical support functions--The combined
    company would be able to eliminate redundant functions in the areas of
    generation support, such as system planning and fuels management.
 
  Field Operations
 
  . Integration of distribution operations--The combined company would have
    the ability to consolidate certain customer business offices and service
    centers in the eastern Kansas area where Western Resources and KCPL have
    contiguous service territories. The close proximity of these operations
    also enables customer service functions such as service initiation,
    service scheduling, etc. to be combined. The close proximity of the two
    companies would enable work to be reconfigured and resources to be shared
    in operations areas and with respect to customer calls and inquiries.
 
  . Integration of field and technical support functions--The combined
    company would be able to eliminate redundant functions in the area of
    distribution support, such as engineering, construction, operation and
    maintenance.
 
  Purchasing Economies
 
  . Streamlining of inventories and purchasing economies--The combined
    company can achieve savings through the centralization of purchasing and
    inventory functions related to construction, operation and maintenance at
    generating plants, service centers, warehouses and headquarters. The
    greater purchasing power and the relative quantity discounts that can be
    obtained as a result of the combination of the two companies would
    provide additional cost savings.
 
  Corporate and Administrative
 
  . Integration of facilities--The combined company would be able to
    consolidate certain duplicative facilities such as corporate headquarters
    and provide opportunities to consolidate energy control centers, service
    centers and warehouses.
 
  . Integration of corporate management and administrative functions--The
    combined company would be able to eliminate redundant functions in the
    areas of finance, accounting, purchasing, shareholder relations, human
    resources, corporate planning, public relations and administration among
    other areas. The payroll costs of such functions are relatively fixed and
    do not vary directly with an increase or decrease in the number of
    customers served.
 
  . Avoidance of future operating system expenditures--The combined company
    would be able to eliminate certain operational expenditures in the area
    of management information systems that would be made by each company on a
    stand-alone basis. These avoided expenditures relate to operating
    systems, such as the customer information and geographic information
    systems, that would not be wholly duplicated in the combined company.
    Additional expenditures could be reduced through the more efficient
    management of investment in other technology areas, such as in personal
    computers, mainframe upgrades and backup facilities.
 
  . Concentration of corporate programs and expenditures--The combined
    company would integrate corporate and administrative functions, thereby
    reducing certain non-labor costs, including insurance, audit and
    consulting fees, professional and trade association dues, stock transfer
    and other fees, vehicle expenses and various license fees, among others.
 
  Based upon Western Resources' experience from the merger with KGE, the cost
savings outlined above can be achieved without layoffs by employing a
combination of attrition, controlled hiring and work management programs (such
as activity standardization or technology substitution).
 
                                      20

  Anticipated net cost savings from the Offer and the Merger are expected to
exceed $1 billion compared to approximately $636 million (derived from the KC
United Registration Statement and the KCPL/UtiliCorp Joint Application)
estimated for the Proposed UtiliCorp/KCPL Transaction over a ten-year period.
Cost savings are greater for the Merger than for the Proposed UtiliCorp/KCPL
Transaction due to the scale differences between the individual companies, the
contiguity and overlap of the KCPL and Western Resources service territories,
the joint ownership or lease by Western Resources as operating lessee of over
$2 billion of generating facilities and the knowledge and experience of
Western Resources in identifying and realizing expected cost savings. The
anticipated merger cost savings for each proposed transaction are summarized
below:

  Although limited information is available to fully compare each category,
Western Resources believes the above table reflects a reasonable comparison.
While figures for UtiliCorp and KCPL reflect the benefits of complete access
to personnel and detailed data within those companies and the identification
of specific cost savings categories, Western Resources has not had similar
access. Nonetheless, Western Resources believes that upon inspection of
similar data and discussions with KCPL personnel, additional cost savings
categories can be identified.
 
  Because Western Resources was unable to discuss the above analyses with KCPL
and did not have access to substantial material concerning KCPL's operations,
these analyses were necessarily limited in scope. In addition, such analyses
involve judgments and contain forward-looking statements with respect to,
among other things, normal weather conditions, future national and regional
economic and competitive conditions, inflation rates, regulatory treatment,
future financial market conditions, interest rates, future business decisions
and other uncertainties, which, though considered reasonable by Western
Resources, are beyond Western Resources' control and difficult to predict.
Accordingly, there can be no assurance that such cost savings will be
realized, and actual cost savings may vary materially from those set forth
above. In light of the uncertainties inherent in such analyses, the inclusion
of estimated cost savings herein should not be regarded as a representation by
Western Resources or any other person that such cost savings will be achieved.
 
  Regulatory Plan. The allocation of the benefits and cost savings outlined
above among the shareholders of Western Resources and KCPL and their
respective customers will depend on the extent by which the rates of Western
Resources and KCPL are adjusted to reflect such benefits. Although no
assurances can be given, Western Resources anticipates that such adjustments
will occur through approval of a regulatory plan (the "Regulatory Plan") that
Western Resources has proposed in its application to the KCC seeking approval
of the Offer and the Merger. The Regulatory Plan includes the following
components:
 
  . An initial rate reduction of $21 million for cumulative rate reductions
    of $210 million for KCPL's retail electric customers in the first 10
    years following the Merger. This is a 30% greater reduction in rates than
    in the Proposed UtiliCorp/KCPL Transaction.
 
  . An initial rate reduction of $10 million and a cumulative rate reduction
    of $100 million for KGE's retail electric customers in the first ten
    years following the Merger.
 
  . A five-year moratorium on electric rate increases for KCPL, KPL, and KGE
    retail customers.
 
  The Regulatory Plan also includes Western Resources' current proposed rate
reduction for KGE which reduces retail electric rates by $8.7 million annually
beginning in August 1996, compounding to $60.9 million at the end of seven
years (the "KGE Rate Plan"). The KGE Rate Plan also provides for acceleration
of annual
 
                                      21
<PAGE>
 
depreciation by $50 million for Wolf Creek for each of the next seven years
and reduces depreciation by $11 million for certain other electric utility
assets to reflect a more appropriate useful life for these properties.
However, there can be no assurance that the Regulatory Plan will be
implemented as described herein. In addition, Western Resources reserves the
right to propose changes to the Regulatory Plan, including changes resulting
from additional information about KCPL becoming available to Western
Resources.
 
  Regulatory Approvals. Regulatory commissions reviewing the Offer and the
Proposed UtiliCorp/KCPL Transaction will be asked to take into account the
greater customer benefits of the Offer when deciding between the applications
for approval.
 
  The consummation of the Offer and the Merger and the Proposed UtiliCorp/KCPL
Transaction both would be subject to approval of the KCC, the Missouri Public
Service Commission ("MPSC"), the Nuclear Regulatory Commission (the "NRC") and
the Federal Energy Regulatory Commission (the "FERC") and the expiration or
termination of the applicable waiting period under the Hart-Scott-Rodino
Antitrust Improvements Act of 1976, as amended, and certain other
miscellaneous filings. These are the only material regulatory approvals
required to effect the Offer and the Merger. By contrast, in addition to all
of the foregoing required regulatory approvals, the Proposed UtiliCorp/KCPL
Transaction would also require approvals from utility regulators in Colorado,
Iowa, Michigan, Minnesota, West Virginia and British Columbia and governmental
approvals in Australia and New Zealand.
 
  On February 2, 1996, KCPL and UtiliCorp jointly filed with the MPSC and the
KCC applications for approval of the Proposed UtiliCorp/KCPL Transaction. The
MPSC and the KCC have scheduled hearings on the Proposed UtiliCorp/KCPL
Transaction to begin, respectively, on October 7, 1996 and November 12, 1996.
On March 29, 1996, KCPL and UtiliCorp jointly filed with the FERC an
application for approval of the Proposed UtiliCorp/KCPL Transaction. As of
April 22, 1996, the FERC had not set the application for hearing.
 
  On April 15, 1996, Western Resources filed an application with the KCC
seeking approval of the Merger and a Petition to Intervene in the Proposed
UtiliCorp/KCPL Transactions.
 
  In light of the superior value of the Offer and the benefits of the
Regulatory Plan described above, Western Resources believes that it will be
able to obtain the necessary regulatory approvals for the Offer on a timely
basis and in a time frame at least as favorable as that in which UtiliCorp
would be able to obtain the necessary regulatory approvals for the Proposed
UtiliCorp/KCPL Transaction. Accordingly, Western Resources believes that the
Proposed UtiliCorp/KCPL Transaction offers no timing advantage over the Offer.
 
THE UTILICORP/KCPL MERGER AGREEMENT
 
  THE FOLLOWING SUMMARY OF CERTAIN PROVISIONS OF THE UTILICORP/KCPL MERGER
AGREEMENT IS TAKEN FROM THE KC UNITED REGISTRATION STATEMENT. THIS SUMMARY
DOES NOT PURPORT TO BE COMPLETE AND IS QUALIFIED IN ITS ENTIRETY BY REFERENCE
TO THE KC UNITED REGISTRATION STATEMENT, WHICH IS INCORPORATED BY REFERENCE
HEREIN, AND THE UTILICORP/KCPL MERGER AGREEMENT, WHICH IS INCLUDED AS APPENDIX
A TO THE KC UNITED REGISTRATION STATEMENT.
 
  The Proposed UtiliCorp/KCPL Transaction. According to the KC United
Registration Statement, the UtiliCorp/KCPL Merger Agreement provides that,
assuming the approval of the UtiliCorp/KCPL Merger Agreement and the Proposed
UtiliCorp/KCPL Transaction by the shareholders of KCPL and UtiliCorp (the
"UtiliCorp/KCPL Shareholder Approvals"), and the satisfaction or waiver of the
other conditions to the Proposed UtiliCorp/KCPL Transaction, including
obtaining the requisite regulatory approvals, KCPL and UtiliCorp would be
merged with and into KC United, with KC United being the surviving
corporation.
 
  If the UtiliCorp/KCPL Shareholder Approvals were obtained, and the other
conditions to the Proposed UtiliCorp/KCPL Transaction were satisfied or
waived, the closing of the Proposed UtiliCorp/KCPL Transaction (the
"UtiliCorp/KCPL Closing") would take place on the second business day
immediately following the date on which the last of the conditions precedent
in the UtiliCorp/KCPL Merger Agreement is fulfilled or waived, or at such
other time and date as KCPL and UtiliCorp would mutually agree (the
"UtiliCorp/KCPL Closing Date").
 
  Subject to the condition that the opinions of Merrill Lynch, Pierce, Fenner
& Smith, Incorporated, financial advisor to KCPL ("Merrill Lynch") and
Donaldson, Lufkin & Jenrette, financial advisor to UtiliCorp ("DLJ") shall not
have been withdrawn, KCPL and UtiliCorp have agreed to call, give notice of,
convene and hold
 
                                      22
<PAGE>
 
meetings of their respective shareholders as soon as reasonably practicable
for the purpose of securing the UtiliCorp/KCPL Shareholder Approvals. Meetings
of the shareholders of KCPL and UtiliCorp are scheduled for May 22, 1996.
 
  Consummation of the Proposed UtiliCorp/KCPL Transaction. If the Proposed
UtiliCorp/KCPL Transaction were consummated (i) each outstanding Share, other
than any shares owned by KCPL, UtiliCorp, KC United or any of their wholly-
owned subsidiaries would be cancelled and converted into the right to receive
one fully paid and nonassessable share, of par value $0.01 per share, of KC
United ("KC United Common Stock") and (ii) each outstanding share of common
stock, par value $0.01 per share, of UtiliCorp ("UtiliCorp Common Stock"),
other than any shares owned by KCPL, UtiliCorp, KC United or any of their
wholly-owned subsidiaries would be cancelled and converted into the right to
receive 1.096 fully paid and nonassessable shares of KC United Common Stock.
No fractional shares of KC United Common Stock would be issued and any
shareholder who would otherwise be entitled to receive a fractional share of
KC United Common Stock would instead be entitled to receive a cash payment in
an amount equal to the product of such fraction multiplied by the average of
the last reported sales price per Share on the NYSE Composite Tape for the
five business days prior to and including the last business day on which
Shares were traded on the NYSE. Based on the amount of Shares and UtiliCorp
Common Stock outstanding as of the date of the UtiliCorp/KCPL Merger
Agreement, the holders of Shares and the holders of UtiliCorp Common Stock
would hold in the aggregate approximately 55% and 45%, respectively, of the
total number of shares of KC United Common Stock outstanding if the Proposed
UtiliCorp/KCPL Transaction is consummated (assuming no shareholders demand and
perfect their dissenters' rights).
 
  Shares held by shareholders who properly demand and perfect their
dissenters' rights ("Dissenting Holders") would not be converted into shares
of KC United Common Stock in the Proposed UtiliCorp/KCPL Transaction and after
the Effective Time would represent only the right to receive such
consideration as is determined to be due such Dissenting Holders pursuant to
the MGBCL. If the Proposed UtiliCorp/KCPL Transaction is consummated, Shares
outstanding immediately prior thereto and held by a shareholder who withdraws
his demand for dissenters' rights or fails to perfect such rights would be
deemed to be converted into the right to receive shares of KC United Common
Stock, as provided above, without interest.
 
  In addition, if the Proposed UtiliCorp/KCPL Transaction were to occur before
March 1, 1997, each outstanding share of preference stock (cumulative), $2.05
Series of UtiliCorp ("UtiliCorp Preferred Stock") would be cancelled and
converted into the right to receive one share of KC United preferred stock. In
the event that the Proposed UtiliCorp/KCPL Transaction has not occurred by
March 1, 1997 (the first date on which the UtiliCorp Preferred Stock may be
redeemed pursuant to the Certificate of Designations for the KC United
preferred stock) or in the event that it becomes apparent that the Proposed
UtiliCorp/KCPL Transaction will not occur by March 1, 1997, the UtiliCorp/KCPL
Merger Agreement obligates UtiliCorp to call for redemption the UtiliCorp
Preferred Stock at or prior to the closing of the Proposed UtiliCorp/KCPL
Transaction. The redemption price would be $25.00 per share of UtiliCorp
Preferred Stock plus all dividends accrued and unpaid to the date fixed for
redemption. If issued, it is intended that the KC United preferred stock would
be redeemed on or after March 1, 1997.
 
  The UtiliCorp/KCPL Merger Agreement requires KCPL to call for redemption
before the effectiveness of the Proposed UtiliCorp/KCPL Transaction all of its
outstanding shares of preferred stock at the applicable redemption prices
therefor, together with all dividends accrued and unpaid through the
applicable redemption dates.
 
  Pursuant to the UtiliCorp/KCPL Merger Agreement, if the Proposed
UtiliCorp/KCPL Transaction is consummated, the certificate of incorporation of
KC United (the "KC United Charter") would be amended and restated to read in
its entirety as set forth in Exhibit 1.1C to the UtiliCorp/KCPL Merger
Agreement, provided that in the event that the UtiliCorp Preferred Stock is
redeemed prior to or as of the Proposed UtiliCorp/KCPL Transaction, the KC
United Charter would, at the option of KCPL and UtiliCorp, be modified as
appropriate to delete language contained therein which relates specifically to
the UtiliCorp Preferred Stock. Also pursuant to the UtiliCorp/KCPL Merger
Agreement, the bylaws of KC United (the "KC United Bylaws") would be
 
                                      23
<PAGE>
 
amended prior to or as of the effectiveness of the Proposed UtiliCorp/KCPL
Transaction to read in their entirety as set forth in Exhibit 1.1D to the
UtiliCorp/KCPL Merger Agreement.
 
  Exchange of Certificates. Assuming the Proposed UtiliCorp/KCPL Transaction
is consummated, an exchange agent mutually agreeable to KCPL and UtiliCorp
(the "UtiliCorp/KCPL Exchange Agent") would mail to each holder of record a
certificate evidencing shares of capital stock of KCPL or UtiliCorp (an "Old
Certificate"), a letter of transmittal and instructions for use in effecting
the surrender of Old Certificates in exchange for certificates representing
shares of KC United Common Stock or KC United preferred stock, as the case may
be. Upon surrender of Old Certificates to the Exchange Agent for cancellation,
together with a duly executed letter of transmittal and such other documents,
if any, as the Exchange Agent shall require, the holder of such Old
Certificates would be entitled to receive a certificate or certificates
representing that number of whole shares of KC United Common Stock or KC
United preferred stock, as the case may be, which such holder would have the
right to receive pursuant to the provisions of the UtiliCorp/KCPL Merger
Agreement. Until surrendered, each Old Certificate would be deemed at any time
after the effectiveness of the Proposed UtiliCorp/KCPL Transaction to
represent only the right to receive upon such surrender the certificate
representing KC United Common Stock or KC United preferred stock, as the case
may be, and cash in lieu of any fractional share of KC United Common Stock.
 
  The letter of transmittal may, at the option of KC United, provide for the
ability of a holder of one or more Old Certificates to elect that the shares
of KC United Common Stock or KC United preferred stock, as the case may be, to
be received be issued in uncertificated form or to elect that such shares be
credited to an account established for the holder under KC United's dividend
reinvestment and stock purchase plan.
 
  No dividends or other distributions declared or made after the effectiveness
of the Proposed UtiliCorp/KCPL Transaction Agreement with respect to KC United
Common Stock or KC United preferred stock with a record date after such
effectiveness would be paid to the holder of any unsurrendered Old
Certificates, and no cash payment in lieu of fractional shares would be paid
to any such holder until such Old Certificates had been surrendered by such
holder. Following such surrender, subject to applicable law, there would be
paid to such holder, without interest, the unpaid dividends and distributions,
and any cash payment in lieu of a fractional share, to which such holder would
be entitled.
 
  Subsidiaries and Joint Ventures. The UtiliCorp/KCPL Merger Agreement defines
"Subsidiary" to mean any corporation or other entity of which at least a
majority of the voting power will at the time be held, directly or indirectly,
by KCPL and UtiliCorp. The UtiliCorp/KCPL Merger Agreement defines "Joint
Venture" to mean specified joint ventures of KCPL or UtiliCorp. The covenants
of KCPL and UtiliCorp in the UtiliCorp/KCPL Merger Agreement apply to the
parties themselves and their Subsidiaries. Certain of the representations and
warranties of KCPL and UtiliCorp in the UtiliCorp/KCPL Merger Agreement apply
to the parties, their Subsidiaries and their Joint Ventures.
 
  Representations and Warranties. The UtiliCorp/KCPL Merger Agreement contains
customary representations and warranties by each of KCPL and UtiliCorp
relating to, among other things and subject to certain qualifications, (a)
their respective organizations, the organization of their respective
Subsidiaries and Joint Ventures and similar corporate matters; (b) their
respective capital structures; (c) the authorization, execution, delivery,
performance and enforceability of the UtiliCorp/KCPL Merger Agreement and
related matters; (d) required regulatory approvals; (e) their compliance with
applicable laws and agreements; (f) reports and financial statements filed
with the Commission or other regulatory authorities and the accuracy of
information contained therein; (g) the absence of any material adverse effect
on their business, assets, financial condition, results of operations or
prospects; (h) the absence of adverse material claims, suits, actions or
proceedings, and other litigation issues; (i) the accuracy of information
supplied by each of KCPL and UtiliCorp for use in the KC United Registration
Statement; (j) tax matters; (k) retirement and other employee benefit plans
and matters relating to the Employee Retirement Income Security Act of 1974,
as amended ("ERISA"); (l) agreements relating to certain employment and
benefits matters; (m) labor matters; (n) compliance with all applicable
material environmental laws, possession of all material environmental, health,

specified states; (p) the shareholder vote required in connection with the
UtiliCorp/KCPL Merger Agreement and the transactions contemplated thereby, as
set forth in the KC United Registration Statement, being the only vote
required; (q) that neither KCPL nor UtiliCorp nor any of their respective

interests; (r) the delivery of fairness opinions by Merrill Lynch, in the case
of KCPL, and DLJ, in the case of UtiliCorp; (s) the adequacy of insurance; and

Incorporation of UtiliCorp, as amended, relating to certain changes in
control.

  The UtiliCorp/KCPL Merger Agreement provides that the parties will execute
such further documents and instruments and take such actions as are necessary
and reasonably requested by the other party to consummate the Proposed
UtiliCorp/KCPL Transaction in accordance with the terms of the UtiliCorp/KCPL
Merger Agreement.
 
  No Solicitation of Transactions. The UtiliCorp/KCPL Merger Agreement
provides that neither KCPL nor UtiliCorp will, and that neither will authorize
or permit any of its officers, directors, employees, accountants, counsel,
investment bankers, financial advisors and other representatives
(collectively, "Representatives") to, directly or indirectly, initiate,
solicit or encourage (including by way of furnishing information) or take any
other action to facilitate knowingly any inquiries or the making of any
proposal which constitutes or may reasonably be expected to lead to an
Acquisition Proposal (as defined below) from any person, or engage in any
discussion or negotiations relating thereto or accept any Acquisition
Proposal; provided, however, that notwithstanding any other provision of the
UtiliCorp/KCPL Merger Agreement, a respective party may (i) at any time prior
to the time the respective parties' shareholders shall have voted to approve
the UtiliCorp/KCPL Merger Agreement, engage in discussions or negotiations
with a third party who (without any solicitation, initiation, encouragement,
discussion or negotiation, directly or indirectly, by or with the party or its
Representatives after January 19, 1996) seeks to initiate such discussions or
negotiations and may furnish such third-party information concerning the party
and its business, properties and assets if, and only to the extent that,
(A)(x) the third party has first made an Acquisition Proposal that is
financially superior to the Proposed UtiliCorp/KCPL Transaction and has
demonstrated that financing for the Acquisition Proposal is reasonably likely
to be obtained (as determined in good faith in each case by the party's board
of directors after consultation with its financial advisors) and (y) the
party's board of directors concludes in good faith, after considering
applicable provisions of state law, on the basis of oral or written advice of
outside counsel that such action is necessary for the board of directors to
act in a manner consistent with its fiduciary duties under applicable law and
(B) prior to furnishing such information to or entering into discussions or
negotiations with such person or entity, such party (x) provides prompt notice
to the other party to the effect that it is furnishing information to or
entering into discussions or negotiations with such person or entity and (y)
receives from such person or entity an executed confidentiality agreement in
reasonably customary form on terms not in the aggregate materially more
favorable to such person or entity than the terms contained in the
UtiliCorp/KCPL confidentiality agreement, dated November 28, 1995 (as amended
from time to time, the "Confidentiality Agreement"), (ii) comply with Rule
14e-2 promulgated under the Exchange Act with regard to a tender or exchange
offer, and/or (iii) accept an Acquisition Proposal from a third party,
provided such respective party terminates the UtiliCorp/KCPL Merger Agreement
pursuant to the provisions of Section 9.1(e) or 9.1(f) thereof, as applicable.
Each party has agreed to cease and terminate any existing solicitation,
initiation, encouragement, activity, discussion or negotiation with any
parties conducted previously by the party or its Representatives with respect
to the foregoing. Each party has agreed to notify the other party orally and
in writing of any such inquiries, offers or proposals (including, without
limitation, the
 
                                      26
<PAGE>
 
terms and conditions of any such proposal and the identity of the person
making it), within 24 hours of the receipt thereof, shall keep the other party
informed of the status and details of any such inquiry, offer or proposal, and
shall give the other party five days' advance notice of any agreement to be
entered into with or any information to be supplied to any person making such
inquiry, offer or proposal. As used herein, "Acquisition Proposal" means any
tender or exchange offer, proposal for a merger, consolidation or other
business combination involving the party or any material Subsidiary of the
party, or any proposal to acquire in any manner a substantial equity interest
in or a substantial portion of the assets of the party or any material
Subsidiary.
 
  KC United Board of Directors. The UtiliCorp/KCPL Merger Agreement provides
that if the Proposed UtiliCorp/KCPL Transaction is consummated, the Directors
of KC United (the "KC United Board") will consist of 18 persons, nine
designated by KCPL and nine designated by UtiliCorp. The initial designation
of such directors among the three classes of the KC United Board will be
agreed to by KCPL and UtiliCorp, the designees of each party to be divided
equally among such classes. If, prior to the time the Proposed UtiliCorp/KCPL
Transaction is consummated, any of such designees declines or is unable to
serve, the party which designated such person will designate another person to
serve in such person's stead. As of the date of the KC United Registration
Statement, KCPL and UtiliCorp have not decided who, in addition to Mr.
Jennings, Chairman of the Board, President and Chief Executive Officer of KCPL
and Mr. Green, Chairman of the Board and Chief Executive Officer of UtiliCorp,
will be designated to serve on the KC United Board after the effectiveness of
the Proposed UtiliCorp/KCPL Transaction. It is currently anticipated that the
directors of KCPL and UtiliCorp prior to the Proposed UtiliCorp/KCPL
Transaction will serve as the initial directors of KC United.
 
  Directors' and Officers' Indemnification. The UtiliCorp/KCPL Merger
Agreement provides that, to the extent, if any, not provided by an existing
right of indemnification or other agreement or policy, from and after the
Proposed UtiliCorp/KCPL Transaction, KC United would, to the fullest extent
permitted by applicable law, indemnify, defend and hold harmless each person
who is on, or who has been at any time prior to, January 19, 1996, or who
becomes prior to the Proposed UtiliCorp/KCPL Transaction, an officer, director
or employee of any of the parties thereto or any Subsidiary (each an
"Indemnified Party," and collectively, "Indemnified Parties") against all
losses, expenses (including reasonable attorney's fees and expenses), claims,
damages or liabilities or, subject to the proviso of the next succeeding
sentence, amounts paid in settlement, arising out of actions or omissions
occurring at or prior to the effectiveness of the Proposed UtiliCorp/KCPL
Transaction (and whether asserted or claimed prior to, at or after the
effectiveness of the Proposed UtiliCorp/KCPL Transaction) that are, in whole
or in part, based on or arising out of the fact that such person is or was a
director, officer or employee of such party, and all such indemnified
liabilities to the extent they are based on or arise out of or pertain to the
transactions contemplated by the UtiliCorp/KCPL Merger Agreement. In the event
of any such loss, expense, claim, damage or liability (whether or not arising
before the effectiveness of the Proposed UtiliCorp/KCPL Transaction), (i) KC
United would pay the reasonable fees and expenses of counsel selected by the
Indemnified Parties, which counsel must be reasonably satisfactory to KC
United, promptly after statements therefor are received and otherwise advance
to such Indemnified Party upon request reimbursement of documented expenses
reasonably incurred, in either case to the extent not prohibited by the
Delaware General Corporate Law, (ii) KC United would cooperate in the defense
of any such matter and (iii) any determination required to be made with
respect to whether an Indemnified Party's conduct complies with the standards
set forth under the Delaware General Corporate Law, the KC United Charter or
the KC United Bylaws would be made by independent counsel mutually acceptable
to KC United and the Indemnified Party; provided, however, that KC United will
not be liable for any settlement effected without its written consent (which
consent must not be unreasonably withheld). The UtiliCorp/KCPL Merger
Agreement further provides that the Indemnified Parties as a group may retain
only one law firm with respect to each related matter except to the extent
there is, in the opinion of counsel to an Indemnified Party, under applicable
standards of professional conduct, a conflict on any significant issue between
positions of such Indemnified Party and any other Indemnified Party or
Indemnified Parties. In addition, the UtiliCorp/KCPL Merger Agreement requires
that for a period of six years after the Proposed UtiliCorp/KCPL Transaction,
KC United will cause to be maintained in effect policies of directors and
officers' liability insurance maintained by KCPL and UtiliCorp for the benefit
of those persons who were covered by such policies on January 19, 1996, on
terms no less favorable than the terms of such insurance coverage, provided
that KC United
 
                                      27
<PAGE>
 
will not be required to expend in any year an amount exceeding 200% of the
annual aggregate premiums currently paid by KCPL and UtiliCorp for such
insurance. If the annual premiums of such insurance coverage exceed such
amount, KC United will be obligated to obtain a policy with the best coverage
available, in the reasonable judgment of the KC United Board, for a cost not
exceeding such amount. The UtiliCorp/KCPL Merger Agreement also provides that
to the fullest extent permitted by law, from and after the effectiveness of
the Proposed UtiliCorp/KCPL Transaction, all rights to indemnification
existing in favor of the employees, agents, directors and officers of KCPL,
UtiliCorp and their respective subsidiaries with respect to their activities
as such prior to the effectiveness of the Proposed UtiliCorp/KCPL Transaction,
as provided in their respective articles of incorporation and bylaws in effect
on January 19, 1996, or otherwise in effect on January 19, 1996, will survive
the Proposed UtiliCorp/KCPL Transaction and will continue in full force and
effect for a period of not less than six years from the effectiveness of the
Proposed UtiliCorp/KCPL Transaction.
 
  Conditions to Each Party's Obligation to Effect the Proposed UtiliCorp/KCPL
Transaction. The respective obligations of KCPL and UtiliCorp to effect the
Proposed UtiliCorp/KCPL Transaction are subject to the following conditions:
(a) the approval of the UtiliCorp/KCPL Merger Agreement and the Proposed
UtiliCorp/KCPL Transaction by the shareholders of KCPL and of UtiliCorp shall
have been obtained; (b) no temporary restraining order, preliminary or
permanent injunction or other order shall be in effect that prevents
consummation of the Proposed UtiliCorp/KCPL Transaction; (c) the KC United
Registration Statement shall have become effective and shall not be the
subject of a stop order; (d) the shares of KC United Common Stock issuable in
connection with the Proposed UtiliCorp/KCPL Transaction shall have been
authorized for listing on the NYSE, upon official notice of issuance; (e) the
receipt of all material governmental authorizations, permits, consents, orders
or approvals which do not impose terms or conditions that could reasonably be
expected to have a material adverse effect; (f) the receipt by each of KCPL
and UtiliCorp of letters from their independent public accountants stating
that the Proposed UtiliCorp/KCPL Transaction will qualify as a pooling of
interests transaction under generally accepted accounting principles and
applicable Commission regulations; (g) with respect to each of KCPL and
UtiliCorp, the performance in all material respects of all obligations of the
other party required to be performed under the UtiliCorp/KCPL Merger
Agreement; (h) with respect to each of KCPL and UtiliCorp, the accuracy of the
representations and warranties of the other party set forth in the
UtiliCorp/KCPL Merger Agreement as of January 19, 1996 and as of the
UtiliCorp/KCPL Closing Date (except as would not reasonably be likely to
result in a material adverse effect); (i) KCPL's and UtiliCorp's having
received officers' certificates from each other stating that certain
conditions set forth in the UtiliCorp/KCPL Merger Agreement have been
satisfied; (j) with respect to each of KCPL and UtiliCorp, there having been
no material adverse effect on the business, assets, financial condition,
results of operations or prospects of the other party and its subsidiaries
taken as a whole; (k) receipt of tax opinions from counsel to each party to
the effect that the Proposed UtiliCorp/KCPL Transaction will be treated as a
tax-free reorganization under Section 368(a) of the Code; (l) with respect to
each of KCPL and UtiliCorp, the receipt by the other party of certain material
third-party consents; and (m) with respect to each of KCPL and UtiliCorp, the
receipt by KC United of letter agreements relating to trading in securities of
KCPL, UtiliCorp and KC United (substantially in the form attached as an
exhibit to the KCPL/UtiliCorp Merger Agreement), duly executed by each
affiliate of the other party.
 
  In addition, the UtiliCorp/KCPL Merger Agreement provides that it is a
condition to the obligation of KCPL to hold the KCPL shareholders meeting that
the opinion of Merrill Lynch shall not have been withdrawn, and it is a
condition to the obligation of UtiliCorp to hold the UtiliCorp Shareholders
Meeting that the opinion of DLJ shall not have been withdrawn.
 
  At any time prior to the effective time of the Proposed UtiliCorp/KCPL
Transaction (the "UtiliCorp/KCPL Effective Time"), to the extent permitted by
applicable law, the conditions to KCPL's or UtiliCorp's obligations to
consummate the Proposed UtiliCorp/KCPL Transaction may be waived by the other
party. Either party's agreement to such a waiver is valid if set forth in a
written instrument signed on behalf of such party.
 
  Benefit Plans. The UtiliCorp/KCPL Merger Agreement provides that KCPL and
UtiliCorp have agreed to cooperate and agree upon the employee benefit plans
and programs to be provided by KC United, and that each
 
                                      28
<PAGE>
 
participant of any KCPL benefit plan or UtiliCorp benefit plan would receive
credit for purposes of eligibility to participate, vesting and eligibility to
receive benefits under any benefit plan of KC United or any of its
subsidiaries or affiliates that replaces a KCPL benefit plan or UtiliCorp
benefit plan; provided, however, that such crediting of service would not
operate to duplicate any benefit to any such participant or the funding for
any such benefit. In addition, the UtiliCorp Supplemental Contributory
Retirement Plan (as defined in the KC United Registration Statement) would be
revised to provide that references to UtiliCorp Common Stock shall instead
refer to KC United Common Stock.
 
 
  If the Proposed UtiliCorp/KCPL Transaction is consummated, no additional
obligations would be incurred under the existing short-term incentive
compensation plans of KCPL and UtiliCorp. Subject to shareholder approval
thereof at the KCPL shareholders meeting and the UtiliCorp shareholders
meeting, the KC United management incentive compensation plan (the "KC United
Stock Incentive Plan") will become effective at the UtiliCorp/KCPL Effective
Time. The KC United Incentive Plan provides for annual bonuses, based on
percentages of base salaries, to be awarded based upon the achievement of
performance goals determined in advance by the KC United Compensation
Committee. With respect to those participants in the new plan who are, or who
the KC United Compensation Committee determines are likely to be, "covered
individuals" within the meaning of Section 162(m) of the Code with
compensation in excess of the limitations set forth in Section 162(m), the
performance goals are to be objective standards that are approved by
shareholders in accordance with the requirements for exclusion from the limits
of Section 162(m) of the Code as performance-based compensation. Following the
implementation of the KC United Stock Incentive Plan, no additional awards
would be made under the existing stock incentive plans of KCPL and UtiliCorp.
Subject to shareholder approval thereof at the KCPL shareholders meeting and
the UtiliCorp shareholders meeting, the KC United Stock Incentive Plan would
become effective at the UtiliCorp/KCPL Effective Time. The KC United Stock
Incentive Plan provides for the grant of stock options, stock appreciation
rights ("SARs"), restricted stock and such other awards based upon KC United
Common Stock as the KC United compensation committee may determine, subject to
shareholder approval of the KC United Stock Incentive Plan. KC United intends
to reserve 9,000,000 shares of KC United Common Stock for issuance under this
plan. Accordingly, the KC United Stock Incentive Plan is being submitted to
shareholders for approval.
 
  If the Proposed UtiliCorp/KCPL Transaction is consummated, (i) each
outstanding option to purchase Shares under the existing stock incentive plans
of KCPL (each, "KCPL Stock Option") and each option to purchase shares of
UtiliCorp Common Stock under the existing stock incentive plans of UtiliCorp
(each, a "UtiliCorp Stock Option") would constitute an option to acquire, on
the same terms and conditions (subject to the adjustments necessary to give
effect to the Proposed UtiliCorp/KCPL Transaction), shares of KC United Common
Stock based on the same number of shares of KC United Common Stock as the
holder of such KCPL Stock Option or UtiliCorp Stock Option would have been
entitled to receive pursuant to the Proposed UtiliCorp/KCPL Transaction had
such holder exercised such option in full immediately prior to the
effectiveness of the Proposed UtiliCorp/KCPL Transaction and (ii) each other
outstanding award under the existing stock incentive plans of KCPL (each, a
"KCPL Stock Award") and the existing stock incentive plans of UtiliCorp (each,
a "UtiliCorp Stock Award") would constitute an award based upon the same
number of shares of KC United Common Stock as the holder of such KCPL Stock
Award or UtiliCorp Stock Award would have been entitled to receive pursuant to
the Proposed UtiliCorp/KCPL Transaction had such holder been the owner,
immediately before the effectiveness of the Proposed UtiliCorp/KCPL
Transaction, of the shares of Shares or UtiliCorp Common Stock on which such
KCPL Stock Award or UtiliCorp Stock Award is based, and otherwise on the same
terms and conditions as governed such KCPL Stock Award or UtiliCorp Stock
Award immediately before the effectiveness of the Proposed UtiliCorp/KCPL
Transaction.

                                   THE OFFER
 
GENERAL
 
  Western Resources hereby offers, upon the terms and subject to the
conditions of the Offer, to exchange that number of shares of Western
Resources Common Stock equal to the Exchange Ratio for each outstanding Share
validly tendered on or prior to the Expiration Date and not withdrawn. The
term "Expiration Date" shall mean 12:00 midnight, New York City time, on
     , 1996, unless and until Western Resources extends the period of time for
which the Offer is open, in which event the term "Expiration Date" shall mean
the latest time and date at which the Offer, as so extended by Western
Resources, shall expire.
 
  Tendering shareholders will not be obligated to pay any charges or expenses
of the Exchange Agent or any brokerage commissions. Except as set forth in the
Instructions to the Letter of Transmittal, transfer taxes on the exchange of
Shares pursuant to the Offer will be paid by or on behalf of Western
Resources.
 
  The purpose of the Offer is for Western Resources to obtain control of, and
ultimately the entire common equity interest in, KCPL. Western Resources
intends, as soon as practicable after consummation of the Offer, to seek to
have KCPL consummate the Merger with Western Resources in which each
outstanding Share (except for treasury shares of KCPL) would be converted into
the right to receive that number of shares of Western Resources Common Stock
equal to the Exchange Ratio. See "--Purpose of the Offer; the Merger."
 
  In the event that Western Resources obtains all of the Shares pursuant to
the Offer and/or the Merger, former shareholders of KCPL would own
approximately 47.7% of the outstanding shares of Western Resources Common
Stock, based on the number of Shares outstanding on April 3, 1996 and stock
prices as of April 19, 1996 (last trading day prior to the date of this
Preliminary Prospectus). If ninety percent of the Shares are exchanged, such
ownership percentage would be approximately 45.1%.
 
  Western Resources' obligation to exchange shares of Western Resources Common
Stock for Shares pursuant to the Offer is conditioned upon satisfaction of the
Offer Conditions. See "--Conditions of the Offer."
 
  According to the KC United Registration Statement, as of April 3, 1996,
there were 61,902,083 Shares outstanding and, together with outstanding
options, 62,061,588 Shares are expected to be outstanding immediately prior to
the consummation of the Proposed UtiliCorp/KCPL Transaction. As of the date of
this Prospectus, Western Resources did not own any Shares.
 
  Requests will be made to KCPL for use of a KCPL Shareholder list and
security position listings for the purpose of communications with KCPL
Shareholders and disseminating the Offer to holders of Shares. The Prospectus
and the related Letter of Transmittal and other relevant materials will be
mailed to record holders of Shares and will be furnished to brokers, dealers,
commercial banks, trust companies and similar persons whose names, or the
names of whose nominees, appear on the shareholder list or, if applicable, who
are listed as participants in a clearing agency's security position listing
for subsequent transmittal to beneficial owners of Shares by Western Resources
following receipt of such list or listings from KCPL.
 
TIMING OF THE OFFER
 
  The Offer is currently scheduled to expire on    , 1996; however, it is
Western Resources' current intention to extend the Offer from time to time as
necessary until all conditions to the Offer have been satisfied or waived. See
"--Extension, Termination and Amendment." Consummation of the Offer and the
Merger is subject to numerous regulatory approvals, which are presently
anticipated to be received by the second quarter of 1997 if the management of
KCPL cooperates; otherwise, such approvals are anticipated to be received by
year-end 1997. See "--Conditions of the Offer--Regulatory Approval Condition."
 
  KCPL shareholders are scheduled to vote on the UtiliCorp/KCPL Merger
Agreement at the KCPL annual meeting to be held on May 22, 1996. If KCPL's
shareholders do not approve the UtiliCorp/KCPL Merger Agreement or the KCPL
board of directors terminates the UtiliCorp/KCPL Merger Agreement, the
UtiliCorp/KCPL
 
                                      30
<PAGE>
 
Merger Agreement Condition will then be satisfied. Western Resources believes
that the KCPL board of directors would at that point respect the vote of the
KCPL Shareholders and take all necessary action in accordance with their
fiduciary duties to allow the Offer and the Merger to proceed.
 
EXTENSION, TERMINATION AND AMENDMENT
 
  Western Resources expressly reserves the right, in its sole discretion, at
any time or from time to time, to extend the period of time during which the
Offer is to remain open by giving oral or written notice of such extension to
the Exchange Agent, which extension must be announced no later than 9:00 A.M.,
New York City time, on the next business day after the previously scheduled
Expiration Date. There can be no assurance that Western Resources will
exercise its right to extend the Offer. However, it is Western Resources'
current intention to extend the Offer until all conditions have been satisfied
or waived. See "--Extension, Termination and Amendment." During any such
extension, all Shares previously tendered and not withdrawn will remain
subject to the Offer, subject to the right of a tendering shareholder to
withdraw his or her Shares. See "--Withdrawal Rights."
 
  Subject to the applicable rules and regulations of the Commission, Western
Resources also reserves the right, in its sole discretion, at any time or from
time to time, (i) to delay acceptance for exchange of or, regardless of
whether such Shares were theretofore accepted for exchange, exchange of any
Shares pursuant to the Offer or to terminate the Offer and not accept for
exchange or exchange any Shares not theretofore accepted for exchange, or
exchanged, upon the failure of any of the conditions of the Offer to be
satisfied and (ii) to waive any condition (other than the Western Resources
Shareholder Approval Condition, the Regulatory Approval Condition and the
condition relating to the effectiveness of the Registration Statement) or
otherwise amend the Offer in any respect, by giving oral or written notice of
such delay, termination or amendment to the Exchange Agent and by making a
public announcement thereof. Any such extension, termination, amendment or
delay will be followed as promptly as practicable by public announcement
thereof, such announcement in the case of an extension to be issued no later
than 9:00 A.M., New York City time, on the next business day after the
previously scheduled Expiration Date. Subject to applicable law (including
Rules 14d-4(c) and 14d-6(d) under the Exchange Act, which requires that any
material change in the information published, sent or given to KCPL
Shareholders in connection with the Offer be promptly disseminated to KCPL
Shareholders in a manner reasonably designed to inform KCPL Shareholders of
such change) and without limiting the manner in which Western Resources may
choose to make any public announcement, Western Resources shall have no
obligation to publish, advertise or otherwise communicate any such public
announcement other than by making a release to the Dow Jones News Service.
 
  Western Resources confirms that if it makes a material change in the terms
of the Offer or the information concerning the Offer, or if it waives a
material condition of the Offer, Western Resources will extend the Offer to
the extent required under the Exchange Act. If, prior to the Expiration Date,
Western Resources shall increase or decrease the percentage of Shares being
sought or the consideration offered to holders of Shares, such increase or
decrease shall be applicable to all holders whose Shares are accepted for
exchange pursuant to the Offer, and, if at the time notice of any such
increase or decrease is first published, sent or given to holders of Shares,
the Offer is scheduled to expire at any time earlier than the tenth business
day from and including the date that such notice is first so published, sent
or given, the Offer will be extended until the expiration of such ten
business-day period. For purposes of the Offer, a "business day" means any day
other than a Saturday, Sunday or a Federal holiday and consists of the time
period from 12:01 A.M. through 12:00 midnight, New York City time.
 
EXCHANGE OF SHARES; DELIVERY OF WESTERN RESOURCES COMMON STOCK
 
  Upon the terms and subject to the conditions of the Offer (including, if the
Offer is extended or amended, the terms and conditions of any such extension
or amendment), Western Resources will accept for exchange, and will exchange,
Shares validly tendered and not withdrawn as promptly as practicable after the
Expiration Date. In addition, subject to applicable rules of the Commission,
Western Resources expressly reserves the right to delay acceptance or exchange
or the exchange of Shares in order to comply with any applicable law. In all
 
                                      31
<PAGE>
 
cases, exchange of Shares tendered and accepted for exchange pursuant to the
Offer will be made only after receipt by the Exchange Agent of certificates
for such Shares (or a confirmation of a book-entry transfer of such Shares in
the Exchange Agent's account at The Depository Trust Company, the Midwest
Securities Trust Company, or the Philadelphia Depository Trust Company
(collectively, the "Book-Entry Transfer Facilities")), a properly completed
and duly executed Letter of Transmittal (or facsimile thereof) and any other
required documents.
 
  For purposes of the Offer, Western Resources will be deemed to have accepted
for exchange Shares validly tendered and not withdrawn as, if and when Western
Resources gives oral or written notice to the Exchange Agent of its acceptance
of the tenders of such Shares pursuant to the Offer. Delivery of Western
Resources Common Stock in exchange for Shares pursuant to the Offer and cash
in lieu of fractional shares of Western Resources Common Stock will be made by
the Exchange Agent as soon as practicable after receipt of such notice. The
Exchange Agent will act as agent for tendering shareholders for the purpose of
receiving Western Resources Common Stock and cash to be paid in lieu of
fractional shares of Western Resources Common Stock from Western Resources and
transmitting such Western Resources Common Stock and cash to tendering KCPL
Shareholders. Under no circumstances will interest with respect to fractional
shares be paid by Western Resources by reason of any delay in making such
exchange.
 
  If any tendered Shares are not accepted for exchange pursuant to the terms
and conditions of the Offer for any reason, or if certificates are submitted
for more Shares than are tendered, certificates for such unexchanged Shares
will be returned without expense to the tendering shareholder or, in the case
of Shares tendered by book-entry transfer of such Shares into the Exchange
Agent's account at a Book-Entry Transfer Facility pursuant to the procedures
set forth below under "--Procedure for Tendering," such Shares will be
credited to an account maintained within such Book-Entry Transfer Facility as
soon as practicable following expiration or termination of the Offer.
 
CASH IN LIEU OF FRACTIONAL SHARES OF WESTERN RESOURCES COMMON STOCK
 
  No certificates representing fractional shares of Western Resources Common
Stock will be issued pursuant to the Offer. In lieu thereof, each tendering
shareholder who would otherwise be entitled to a fractional share of Western
Resources Common Stock will receive cash in an amount equal to such fraction
(expressed as a decimal and rounded to the nearest 0.01 of a share) times the
closing price for shares of Western Resources Common Stock on the NYSE
Composite Tape on the date such KCPL Shareholder's Shares are accepted for
exchange by Western Resources.
 
WITHDRAWAL RIGHTS
 
  Tenders of Shares made pursuant to the Offer are irrevocable, except that
Shares tendered pursuant to the Offer may be withdrawn at any time prior to
the Expiration Date, and, unless theretofore accepted for exchange by Western
Resources pursuant to the Offer, may also be withdrawn at any time after    ,
1996.
 
  For a withdrawal to be effective, a written, telegraphic, telex or facsimile
transmission notice of withdrawal must be timely received by the Exchange
Agent at one of its addresses set forth on the back cover of this Prospectus
and must specify the name of the person having tendered the Shares to be
withdrawn, the number of Shares to be withdrawn and the name of the registered
holder, if different from that of the person who tendered such Shares.
 
  The signature(s) on the notice of withdrawal must be guaranteed by a
financial institution (including most banks, savings and loan associations and
brokerage houses) which is a participant in the Securities Transfer Agents
Medallion Program, the New York Stock Exchange Medallion Signature Program or
the Stock Exchange Medallion Program (an "Eligible Institution") unless such
Shares have been tendered for the account of any Eligible Institution. If
Shares have been tendered pursuant to the procedures for book-entry tender as
set forth below under "--Procedure for Tendering," any notice of withdrawal
must specify the name and number of the
 
                                      32
<PAGE>
 
account at the Book-Entry Transfer Facility to be credited with the withdrawn
Shares and must otherwise comply with such Book-Entry Transfer Facility's
procedures. If certificates have been delivered or otherwise identified to the
Exchange Agent, the name of the registered holder and the serial numbers of
the particular certificates evidencing the Shares withdrawn must also be
furnished to the Exchange Agent as aforesaid prior to the physical release of
such certificates.
 
  All questions as to the form and validity (including time of receipt) of any
notice of withdrawal will be determined by Western Resources, in its sole
discretion, which determination shall be final and binding. Neither Western
Resources, the Exchange Agent, the Information Agent, the Dealer Manager nor
any other person will be under any duty to give notification of any defects or
irregularities in any notice of withdrawal or will incur any liability for
failure to give any such notification. Any Shares properly withdrawn will be
deemed not to have been validly tendered for purposes of the Offer. However,
withdrawn Shares may be retendered by following one of the procedures
described under "--Procedure for Tendering" at any time prior to the
Expiration Date.
 
PROCEDURE FOR TENDERING
 
  For a KCPL Shareholder validly to tender Shares pursuant to the Offer, (i) a
properly completed and duly executed Letter of Transmittal (or manually
executed facsimile thereof), together with any required signature guarantees,
or an Agent's Message (as defined below) in connection with a book-entry
transfer, and any other required documents, must be transmitted to and
received by the Exchange Agent at one of its addresses set forth on the back
cover of this Prospectus and certificates for tendered Shares must be received
by the Exchange Agent at such address or such Shares must be tendered pursuant
to the procedures for book-entry tender set forth below (and a confirmation of
receipt of such tender received (such confirmation, a "Book-Entry
Confirmation")), in each case prior to the Expiration Date, or (ii) such KCPL
Shareholder must comply with the guaranteed delivery procedure set forth
below.
 
  The term "Agent's Message" means a message, transmitted by a Book-Entry
Transfer Facility to, and received by, the Exchange Agent and forming a part
of a Book-Entry Confirmation, which states that such Book-Entry Transfer
Facility has received an express acknowledgment from the participant in such
Book-Entry Transfer Facility tendering the Shares that such participant has
received and agrees to be bound by the terms of the Letter of Transmittal and
that Western Resources may enforce such agreement against such participant.
 
  The Exchange Agent will establish accounts with respect to the Shares at the
Book-Entry Transfer Facilities for purposes of the Offer within two business
days after the date of this Prospectus, and any financial institution that is
a participant in any of the Book-Entry Transfer Facilities' systems may make
book-entry delivery of the Shares by causing such Book-Entry Transfer Facility
to transfer such Shares into the Exchange Agent's account in accordance with
such Book-Entry Transfer Facility's procedure for such transfer. However,
although delivery of Shares may be effected through book-entry at the Book-
Entry Transfer Facilities, the Letter of Transmittal (or facsimile thereof),
with any required signature guarantees, or an Agent's Message in connection
with a book-entry transfer, and any other required documents, must, in any
case, be transmitted to and received by the Exchange Agent at one or more of
its addresses set forth on the back cover of this Prospectus prior to the
Expiration Date, or the guaranteed delivery procedure described below must be
complied with.
 
  Signatures on all Letters of Transmittal must be guaranteed by an Eligible
Institution, except in cases in which Shares are tendered (i) by a registered
holder of Shares who has not completed either the box entitled "Special
Payment Instructions" or the box entitled "Special Delivery Instructions" on
the Letter of Transmittal or (ii) for the account of an Eligible Institution.
If the certificates for Shares are registered in the name of a person other
than the signer of the Letter of Transmittal, or if certificates for
unexchanged Shares are to be issued to a person other than the registered
holder(s), the certificates must be endorsed or accompanied by appropriate
stock powers, in either case signed exactly as the name or names of the
registered owner or owners appear on the certificates, with the signature(s)
on the certificates or stock powers guaranteed as aforesaid.
 
                                      33
<PAGE>
 
  THE METHOD OF DELIVERY OF SHARE CERTIFICATES AND ALL OTHER REQUIRED
DOCUMENTS, INCLUDING DELIVERY THROUGH ANY BOOK-ENTRY TRANSFER FACILITY, IS AT
THE OPTION AND RISK OF THE TENDERING SHAREHOLDER, AND THE DELIVERY WILL BE
DEEMED MADE ONLY WHEN ACTUALLY RECEIVED BY THE EXCHANGE AGENT. IF DELIVERY IS
BY MAIL, REGISTERED MAIL WITH RETURN RECEIPT REQUESTED, PROPERLY INSURED, IS
RECOMMENDED. IN ALL CASES, SUFFICIENT TIME SHOULD BE ALLOWED TO ENSURE TIMELY
DELIVERY.
 
  TO PREVENT BACKUP FEDERAL INCOME TAX WITHHOLDING WITH RESPECT TO CASH
RECEIVED IN LIEU OF FRACTIONAL SHARES OF WESTERN RESOURCES COMMON STOCK, A
SHAREHOLDER MUST PROVIDE THE EXCHANGE AGENT WITH HIS OR HER CORRECT TAXPAYER
IDENTIFICATION NUMBER AND CERTIFY WHETHER SUCH SHAREHOLDER IS SUBJECT TO
BACKUP WITHHOLDING OF FEDERAL INCOME TAX BY COMPLETING THE SUBSTITUTE FORM W-9
INCLUDED IN THE LETTER OF TRANSMITTAL. CERTAIN SHAREHOLDERS (INCLUDING, AMONG
OTHERS, ALL CORPORATIONS AND CERTAIN FOREIGN INDIVIDUALS) ARE NOT SUBJECT TO
THESE BACKUP WITHHOLDING AND REPORTING REQUIREMENTS. IN ORDER FOR A FOREIGN
INDIVIDUAL TO QUALIFY AS AN EXEMPT RECIPIENT, THE SHAREHOLDER MUST SUBMIT A
FORM W-8, SIGNED UNDER PENALTIES OF PERJURY, ATTESTING TO THAT INDIVIDUAL'S
EXEMPT STATUS.
 
  If a KCPL Shareholder desires to tender Shares pursuant to the Offer and
such shareholder's certificates are not immediately available or such
shareholder cannot deliver the certificates and all other required documents
to the Exchange Agent prior to the Expiration Date or such shareholder cannot
complete the procedure for book-entry transfer on a timely basis, such Shares
may nevertheless be tendered, provided that all of the following conditions
are satisfied:
 
    (a) such tenders are made by or through an Eligible Institution;
 
    (b) a properly completed and duly executed Notice of Guaranteed Delivery,
  substantially in the form made available by Western Resources, is received
  by the Exchange Agent as provided below on or prior to the Expiration Date;
  and
 
    (c) the certificates for all tendered Shares (or a confirmation of a
  book-entry transfer of such securities into the Exchange Agent's account at
  a Book-Entry Transfer Facility as described above), in proper form for
  transfer, together with a properly completed and duly executed Letter of
  Transmittal (or facsimile thereof), with any required signature guarantees
  (or, in the case of a book-entry transfer, an Agent's Message) and all
  other documents required by the Letter of Transmittal are received by the
  Exchange Agent within three NYSE trading days after the date of execution
  of such Notice of Guaranteed Delivery.
 
  The Notice of Guaranteed Delivery may be delivered by hand or transmitted by
telegram, telex, facsimile transmission or mail to the Exchange Agent and must
include a guarantee by an Eligible Institution in the form set forth in such
Notice.
 
  In all cases, exchanges of Shares tendered and accepted for exchange
pursuant to the Offer will be made only after timely receipt by the Exchange
Agent of certificates for Shares (or timely confirmation of a book-entry
transfer of such securities into the Exchange Agent's account at a Book-Entry
Transfer Facility as described above), properly completed and duly executed
Letter(s) of Transmittal (or facsimile(s) thereof), or an Agent's Message in
connection with a book-entry transfer, and any other required documents.
Accordingly, tendering KCPL Shareholders may be paid at different times
depending upon when certificates for Shares or confirmations of book-entry
transfers of such Shares are actually received by the Exchange Agent.
 
  By executing a Letter of Transmittal as set forth above, the tendering KCPL
Shareholder irrevocably appoints designees of Western Resources as such
shareholder's attorneys-in-fact and proxies, each with full power of
substitution, to the full extent of such shareholder's rights with respect to
the Shares tendered by such
 
                                      34
<PAGE>
 
shareholder and accepted for exchange by Western Resources and with respect to
any and all other Shares and other securities issued or issuable in respect of
the Shares on or after      , 199 . Such appointment is effective, and voting
rights will be affected, when and only to the extent that Western Resources
deposits the shares of Western Resources Common Stock for Shares tendered by
such shareholder with the Exchange Agent. All such proxies shall be considered
coupled with an interest in the tendered Shares and therefore shall not be
revocable. Upon the effectiveness of such appointment, all prior proxies given
by such shareholder will be revoked, and no subsequent proxies may be given
(and, if given, will not be deemed effective). Western Resources' designees
will, with respect to the Shares for which the appointment is effective, be
empowered, among other things, to exercise all voting and other rights of such
shareholder as they, in their sole discretion, deem proper at any annual,
special or adjourned meeting of KCPL Shareholders, by written consent in lieu
of any such meeting or otherwise. Western Resources reserves the right to
require that, in order for Shares to be deemed validly tendered, immediately
upon Western Resources' exchange of such Shares, Western Resources must be
able to exercise full voting rights with respect to such Shares.
 
  All questions as to the validity, form, eligibility (including time of
receipt) and acceptance for exchange of any tender of Shares will be
determined by Western Resources, in its sole discretion, which determination
shall be final and binding. Western Resources reserves the absolute right to
reject any and all tenders of Shares determined by it not to be in proper form
or the acceptance of or exchange for which may, in the opinion of Western
Resources' counsel, be unlawful. Western Resources also reserves the absolute
right to waive any of the conditions of the Offer (other than the Western
Resources Shareholder Approval Condition, the Regulatory Approval Condition
and the condition relating to the effectiveness of the Registration
Statement), or any defect or irregularity in the tender of any Shares. No
tender of Shares will be deemed to have been validly made until all defects
and irregularities in tenders of Shares have been cured or waived. Neither
Western Resources, the Exchange Agent, the Information Agent, the Dealer
Manager nor any other person will be under any duty to give notification of
any defects or irregularities in the tender of any Shares or will incur any
liability for failure to give any such notification. Western Resources'
interpretation of the terms and conditions of the Offer (including the Letter
of Transmittal and instructions thereto) will be final and binding.
 
  The tender of Shares pursuant to any of the procedures described above will
constitute a binding agreement between the tendering KCPL Shareholder and
Western Resources upon the terms and subject to the conditions of the Offer.
 
CERTAIN FEDERAL INCOME TAX CONSEQUENCES
 
  In the opinions of Sullivan & Cromwell and LeBoeuf, Lamb, Greene & MacRae,
L.L.P., special counsel to Western Resources, exchanges of Shares for Western
Resources Common Stock pursuant to the Offer and the Merger should be treated
for federal income tax purposes as exchanges pursuant to a plan of
reorganization within the meaning of the Code. Consequently, if the Offer and
the Merger qualify as a reorganization, no gain or loss will be recognized by
holders of Shares upon such exchanges, except as described below under "--Tax
Consequences to Holders of Shares if the Offer and the Merger Qualify as a
Reorganization." These opinions are based on Sullivan & Cromwell's and
LeBoeuf, Lamb, Greene & MacRae, L.L.P.'s view that the Offer and the Merger
should be treated as a single transaction and on certain assumptions,
including that (a) the continuity of shareholder interest requirement
applicable to corporate reorganizations (which requires a continuing equity
interest in Western Resources by holders owning a significant percentage of
the Shares prior to the consummation of the Offer) will be satisfied, taking
into account any holders of Shares who exercise dissenters' rights, if any,
(b) Western Resources will continue KCPL's historic business or will use a
significant portion of KCPL's historic business assets in a business, and (c)
the Offer and the Merger will generally be consummated as contemplated by this
Prospectus. Although there are currently no binding agreements that would
ensure that the KCPL Shareholders will have a continuing equity interest in
Western Resources following the consummation of the Offer and the Merger,
Western Resources believes that it is likely that the shareholders of KCPL
will retain a sufficient amount of the stock of Western Resources to satisfy
the continuity of interest requirement.
 
  In rendering their opinions, Sullivan & Cromwell and LeBoeuf, Lamb, Greene &
MacRae, L.L.P. have further assumed that (a) upon consummation of the Offer,
there will be no significant contingencies preventing
 
                                      35
<PAGE>
 
the prompt consummation of the Merger, (b) upon consummation of the Offer,
Western Resources will not have waived any of the conditions relating to its
obligation to consummate the Offer in a manner that could prevent a prompt
consummation of the Merger, (c) the Merger will in fact be consummated
promptly after the consummation of the Offer and in no event more than one
year after the consummation of the Offer and (d) either KCPL will have, at the
time the Offer is consummated, entered into an agreement with Western
Resources requiring Western Resources to effect the Merger or the "binding
commitment" test discussed below will not apply to the Offer and the Merger. A
significant delay in the consummation of the Merger would substantially
increase the risk that the Offer will not qualify as part of a reorganization
within the meaning of Section 368(a)(1)(A) of the Code and the absence of the
Merger would mean that the Offer was not part of a reorganization. The
consequences of a failure to so qualify are discussed below under "--Tax
Consequences to Holders of Shares if the Offer Does Not Qualify as Part of a
Reorganization."
 
  In deciding whether two steps are part of a single transaction qualifying as
a reorganization, some courts have applied the so-called "binding commitment"
test. Under that test, two steps will be integrated only if, at the time that
the first step is consummated, there is a binding commitment to consummate the
second step. If the "binding commitment" test were applied to the Offer and
the Merger and KCPL has not at the time the Offer is consummated entered into
an agreement with Western Resources requiring Western Resources to effect the
Merger, the Offer and the Merger would not be treated as a single transaction,
and the Offer would not qualify as part of a reorganization. Although the
matter is not free from doubt, in the opinion of Sullivan & Cromwell and
LeBoeuf, Lamb, Greene & MacRae, L.L.P., the "binding commitment" test should
not be applied to determine whether the Offer and the Merger should be treated
as a single transaction.
 
  Assuming that the Merger qualifies as a reorganization under the Code, no
gain or loss will be recognized by Western Resources or KCPL as a result of
the Offer and the Merger.
 
  This summary does not address any tax consequences of the Offer or the
Merger to U.S. Holders who exercise dissenters' rights, if any. It may not
apply to certain classes of taxpayers, including, without limitation,
insurance companies, tax-exempt organizations, financial institutions, dealers
in securities, foreign persons, persons who acquired Shares pursuant to an
exercise of employee stock options or rights or otherwise as compensation and
persons who hold Shares as part of a straddle or conversion transaction. Also,
the summary does not address state, local or foreign tax consequences of the
Offer or the Merger. Consequently, each holder should consult such holder's
own tax advisor as to the specific tax consequences of the Offer and the
Merger to such holder.
 
  This summary is based on current law and the respective opinions of Sullivan
& Cromwell and LeBoeuf, Lamb, Greene & MacRae, L.L.P. Future legislative,
judicial or administrative changes or interpretations, which may be
retroactive, could alter or modify the statements set forth herein. The
opinions of Sullivan & Cromwell and LeBoeuf, Lamb, Greene & MacRae, L.L.P. set
forth in this summary are based, among other things, on the assumptions set
forth above, which assumptions have been made with the consent of Western
Resources. Western Resources will not request any ruling from the Internal
Revenue Service as to the United States federal income tax consequences of the
Offer and the Merger. An opinion of counsel is not binding on the Internal
Revenue Service, and the Internal Revenue Service is not precluded from taking
contrary positions.
 
  Tax Consequences to Holders of Shares if the Offer and the Merger Qualify as
a Reorganization. If the Offer and the Merger together qualify as a
reorganization within the meaning of Section 368(a)(1)(A) of the Code, the
material federal income tax consequences to holders who are (a) citizens or
residents of the United States, (b) domestic corporations or (c) otherwise
subject to United States federal income tax on a net income basis in respect
of the Shares ("U.S. Holders") who hold Shares as capital assets and who
exchange such Shares pursuant to the Offer or the Merger, or both, will be as
follows:
 
    (i) no gain or loss will be recognized by a U.S. Holder on the exchange
  of Shares for Western Resources Common Stock, except as described below
  with respect to the receipt of cash in lieu of fractional shares of Western
  Resources Common Stock;
 
                                      36
<PAGE>
 
    (ii) the aggregate adjusted tax basis of shares of Western Resources
  Common Stock received by a U.S. Holder (including fractional shares of
  Western Resources Common Stock deemed received and redeemed as described
  below) will be the same as the aggregate adjusted tax basis of the Shares
  exchanged therefor;
 
    (iii) the holding period of shares of Western Resources Common Stock
  (including the holding period of fractional shares of Western Resources
  Common Stock) received by a U.S. Holder will include the holding period of
  the Shares exchanged therefor; and
 
    (iv) a U.S. Holder of Shares who receives cash in lieu of fractional
  shares of Western Resources Common Stock will be treated as having received
  such fractional shares and then as having received such cash in redemption
  of such fractional shares. Under Section 302 of the Code, provided that
  such deemed distribution is "substantially disproportionate" with respect
  to such U.S. Holder or is "not essentially equivalent to a dividend" after
  giving effect to the constructive ownership rules of the Code, the U.S.
  Holder will generally recognize capital gain or loss equal to the
  difference between the amount of cash received and the U.S. Holder's
  adjusted tax basis in the fractional share interest in Western Resources
  Common Stock. Such capital gain or loss will be long-term capital gain or
  loss if the U.S. Holder's holding period in the fractional shares is more
  than one year.
 
  Tax Consequences to Holders of Shares if the Offer Does Not Qualify as Part
of a Reorganization. If the Merger is not consummated, or if the Merger is
consummated but the Offer is treated as a separate transaction for federal
income tax purposes, the Offer may fail to meet all of the requirements of a
tax-free reorganization and exchanges pursuant to the Offer may therefore be
taxable transactions for federal income tax purposes. In that case, each U.S.
Holder exchanging Shares for shares of Western Resources Common Stock pursuant
to the Offer will recognize gain or loss for federal income tax purposes
measured by the difference between such U.S. Holder's adjusted basis in the
Shares exchanged and the sum of the fair market value of Western Resources
Common Stock received by such U.S. Holder pursuant to the Offer and any cash
received by such U.S. Holder in lieu of fractional shares of Western Resources
Common Stock.
 
  If the Offer is a taxable transaction, the Merger itself would be a
reorganization within the meaning of Section 368(a)(1)(A) of the Code if the
continuity of interest requirement is satisfied in the Merger. For advance
ruling purposes, guidelines published by the Internal Revenue Service would
require that shareholders of KCPL receive in the Merger stock of Western
Resources having a value equal to at least 50% of the value of all of the
stock of KCPL outstanding prior to the Merger. If the Offer is treated as a
separate transaction for federal income tax purposes, however, Western
Resources Common Stock issued in the Offer should count towards establishing
that the Merger satisfies the continuity of interest requirement. If the
continuity of interest requirement is satisfied in the Merger, a U.S. Holder
receiving Western Resources Common Stock in the Merger would be subject to the
rules concerning reorganizations described above with respect to such Western
Resources Common Stock, but not with respect to any Western Resources Common
Stock received by such U.S. Holder pursuant to the Offer.
 
EFFECT OF OFFER ON MARKET FOR SHARES; REGISTRATION UNDER THE EXCHANGE ACT
 
  The exchange of Shares pursuant to the Offer will reduce the number of
holders of Shares and the number of Shares that might otherwise trade publicly
and could adversely affect the liquidity and market value of the remaining
Shares held by the public.
 
  The Shares are listed and principally traded on the NYSE and are also listed
on the CSE. Depending upon the number of Shares acquired pursuant to the
Offer, following consummation of the Offer the Shares may no longer meet the
requirements of such exchanges for continued listing. For example, published
guidelines of the NYSE indicate that the NYSE would consider delisting the
outstanding Shares if, among other things, (i) the number of publicly held
Shares (exclusive of holdings of officers, directors and members of their
immediate families and other concentrated holdings of 10 percent or more)
should fall below 600,000, (ii) the number of
 
                                      37
<PAGE>
 
record holders of 100 or more Shares should fall below 1,200 or (iii) the
aggregate market value of publicly held Shares should fall below $5 million.
 
  According to the KC United Registration Statement, there were, as of April
3, 1996, 61,902,083 Shares outstanding and 62,061,588 Shares are expected to
be outstanding immediately prior to the closing of the Proposed UtiliCorp/KCPL
Transaction. According to the KCPL 1995 Form 10-K, there were, as of December
31, 1995, 29,657 holders of record of Shares.
 
  If such exchanges were to delist the Shares, the market therefor could be
adversely affected. It is possible that the Shares would be traded on other
securities exchanges or in the over-the-counter market, and that price
quotations would be reported by such exchanges, or through Nasdaq or by other
sources. The extent of the public market for the Shares and the availability
of such quotations would, however, depend upon the number of holders and/or
the aggregate market value of the Shares remaining at such time, the interest
in maintaining a market in the Shares on the part of securities firms, the
possible termination of registration of Shares under the Exchange Act, as
described below, and other factors.
 
  The Shares are presently "margin securities" under the regulations of the
Federal Reserve Board, which has the effect, among other things, of allowing
brokers to extend credit on the collateral of such Shares. Depending on
factors similar to those described above with respect to listing and market
quotations, following consummation of the Offer the Shares may no longer
constitute "margin securities" for the purposes of the Federal Reserve Board's
margin regulations, in which event the Shares would be ineligible as
collateral for margin loans made by brokers. For a description of the
treatment of Shares in the Merger, see "--Purpose of the Offer; the Merger."
 
  The Shares are currently registered under the Exchange Act. Such
registration may be terminated by KCPL upon application to the Commission if
the outstanding Shares are not listed on a national securities exchange and if
there are fewer than 300 holders of record of Shares. Termination of
registration of the Shares under the Exchange Act would reduce the information
required to be furnished by KCPL to its shareholders and to the Commission and
would make certain provisions of the Exchange Act, such as the short-swing
profit recovery provisions of Section 16(b) and the requirement of furnishing
a proxy statement in connection with shareholders' meetings pursuant to
Section 14(a) and the related requirement of furnishing an annual report to
shareholders, no longer applicable with respect to the Shares. Furthermore,
the ability of "affiliates" of KCPL and persons holding "restricted
securities" of KCPL to dispose of such securities pursuant to Rule 144 under
the Securities Act may be impaired or eliminated. If registration of the
Shares under the Exchange Act were terminated, the Shares would no longer be
eligible for Nasdaq reporting or for continued inclusion on the Federal
Reserve Board's list of "margin securities."
 
PURPOSE OF THE OFFER; THE MERGER
 
  The purpose of the Offer is to obtain control of, and ultimately the entire
common equity interest in, KCPL. Western Resources intends, as soon as
practicable after consummation of the Offer, to seek to merge KCPL with and
into Western Resources pursuant to Section 351.447 of the MGBCL and Section
17-6703 of the KCC. Under Section 351.447 and Section 17-6703, assuming the
Minimum Tender Condition, the Western Resources Shareholder Approval
Condition, the Missouri Control Share Acquisition Condition, the Missouri
Business Combination Condition, the UtiliCorp/KCPL Merger Agreement Condition,
the Regulatory Approval Condition and the KCPL Preferred Stock Redemption
Condition are satisfied, Western Resources could consummate the Merger without
any additional vote of the holders of Western Resources Common Stock or any
vote of KCPL Shareholders. See "--Conditions of the Offer--Short Form Merger
Condition." Pursuant to the Merger, each outstanding Share (except for Shares
held in the treasury of KCPL and Shares held by shareholders who properly
exercise their dissenters' rights, if any, under Missouri law) would be
converted into the right to receive a number
of shares of Western Resources Common Stock equal to the Exchange Ratio. See
"The Offer--Dissenters' Rights."
 
                                      38
<PAGE>
 
  Pursuant to Section 351.447 of the MGBCL, a parent corporation that owns 90%
of the outstanding shares of each class of a corporation may merge such
corporation with and into itself (a "short-form merger") without a vote of the
subsidiary's shareholders. Pursuant to Sections 351.447 and 351.455 of the
MGBCL, if the subsidiary in a short-form merger is a Missouri corporation, a
shareholder of such subsidiary corporation other than the parent may, by
following the procedures summarized below in "--Dissenters' Rights," demand
that the surviving corporation pay him the fair value of his shares (exclusive
of any element of value arising from the expectation or accomplishment of the
short-form merger).
 
  Rule 13e-3 of the General Rules and Regulations under the Exchange Act,
which Western Resources does not believe would be applicable to the Merger if
the Merger occurred within one year of consummation of the Offer, would
require, among other things, that certain financial information concerning
KCPL, and certain information relating to the fairness of the proposed
transaction and the consideration offered to shareholders of KCPL therein, be
filed with the Commission and disclosed to shareholders of KCPL prior to
consummation of the Merger.
 
  In addition, Western Resources reserves the right to acquire, following the
consummation or termination of the Offer, additional Shares through open
market purchases, privately negotiated transactions, a tender offer or
exchange offer, or otherwise, upon such terms and at such prices as it shall
determine, which may be more or less favorable than those of the Offer.
Western Resources and its affiliates also reserve the right to (i) dispose of
any or all Shares acquired by them pursuant to the Offer or otherwise, upon
such terms and at such prices as they shall determine and (ii) purchase shares
of any class of preferred stock of KCPL ("KCPL Preferred Stock").
 
  In connection with the Offer, Western Resources has reviewed, and will
continue to review, on the basis of available information, various possible
business strategies that it might consider in the event that it acquires all
or substantially all of the common equity interest in KCPL. Western Resources
also intends to conduct a detailed review of KCPL and its assets, corporate
structure, capitalization, operations, properties, policies, management and
personnel and consider which changes, if any, would be desirable in light of
the circumstances which then exist. Such strategies could include, among other
things, changes in KCPL's business, corporate structure, certificate of
incorporation, bylaws, capitalization, the KCPL Board of Directors or
management, and consideration of disposition of certain assets or lines of
business of KCPL.
 
  Except as noted herein, Western Resources does not have any present plans or
proposals that would result in an extraordinary corporate transaction, such as
a merger, reorganization or liquidation, or sale or transfer of a material
amount of assets, involving KCPL or any of its subsidiaries, or any material
changes in KCPL's corporate structure or business or any change in its
management. However, because Western Resources has not had access to KCPL's
books and records, additional changes may be made after a full review of
KCPL's operations is completed.
 
DISSENTERS' RIGHTS
 
  In connection with the Merger and pursuant to Sections 351.447 and 351.455
of the MGBCL, a KCPL Shareholder may, by following the procedures summarized
below, demand in writing that Western Resources pay him the fair value of his
Shares. Within ten days after the effective date of the Merger, Western
Resources will notify each holder of Shares still outstanding immediately
after consummation of the Offer by registered or certified mail (return
receipt requested) delivered to the address of such shareholder appearing in
the records of KCPL that the Merger has occurred. A dissenting shareholder
then has twenty days after the mailing of such notice to demand in writing the
fair value of his Shares immediately prior to the Merger, exclusive of any
element of value arising from the expectation or accomplishment of the Merger.
Demands for the payment of fair value should be addressed to: Western
Resources, Inc., Attention: Corporate Secretary, 818 Kansas Avenue, Topeka,
Kansas 66612.
 
  A beneficial owner of Shares who is not the record owner may not assert
dissenters' rights. If the stock is owned of record in a fiduciary capacity,
such as by a trustee, guardian or custodian, or by a nominee, the written
 
                                      39
<PAGE>
 
demand asserting dissenters' rights must be executed by the fiduciary or
nominee. If the Shares are owned of record by more than one person, as in a
joint tenancy or tenancy in common, the demand must be executed by all joint
owners. An authorized agent, including an agent for two or more joint owners,
may execute the demand for a shareholder of record; however, the agent must
identify the record owner, disclose the fact that, in executing the demand, he
is acting as agent for the record owner and provide evidence of his authority.
 
  If Western Resources and the dissenting shareholder do not agree on the fair
value of the Shares within thirty days after the end of such twenty-day
period, then the shareholder has an additional sixty days after the end of the
thirty-day period to file a petition asking for a determination of such fair
value in a court of competent jurisdiction in the county where Western
Resources maintains its registered Missouri office. The shareholder is
entitled to judgment against Western Resources for the fair value of its
Shares, excluding any element of value arising from the expectation or
accomplishment of the Merger, together with interest thereon to the date of
such judgment. The judgment shall be payable only upon, and simultaneously
with, the surrender to Western Resources of the certificate or certificates
representing shares with respect to which dissenters' rights have been
exercised. Upon the payment of the judgment, the dissenting shareholder shall
cease to have any interest in such Shares or in Western Resources. Such Shares
may be held and disposed of by Western Resources as it may see fit. Unless the
dissenting shareholder shall file such petition within such sixty day period,
such shareholder and all persons claiming under such shareholder shall be
conclusively presumed to have approved and ratified the Merger and shall be
bound by the terms thereof.
 
  The right of a dissenting shareholder to be paid the fair value of the
shareholder's shares shall cease if the shareholder fails to comply with the
procedures set forth in Sections 351.447 and 351.455 and described above, or
if the Merger is abandoned for any reason.
 
  The foregoing does not purport to be a complete statement of the procedures
to be followed by shareholders desiring to exercise dissenters' rights and, in
view of the fact that exercise of such rights requires strict adherence to the
relevant provisions of the MGBCL, shareholders who desire to exercise
appraisal rights are advised to review with care all applicable provisions of
law and to obtain legal counsel concerning proper compliance with applicable
provisions of the MGBCL. HOLDERS OF SHARES ARE URGED TO, AND SHOULD, READ
SECTIONS 351.447 AND 351.455 OF THE MGBCL, A COPY OF WHICH IS ATTACHED HERETO
AS SCHEDULE B IN ITS ENTIRETY AND INCORPORATED HEREIN BY REFERENCE.
 
CONDITIONS OF THE OFFER
 
  Minimum Tender Condition. The Offer is conditioned upon, among other things,
there being validly tendered and not withdrawn prior to the Expiration Date a
number of Shares which will constitute at least ninety percent (90%) of the
total number of outstanding Shares on a fully diluted basis (as though all
options or other securities convertible into or exercisable or exchangeable
for Shares had been so converted, exercised or exchanged) as of the date the
Shares are accepted for exchange by Western Resources pursuant to the Offer.
Based upon information set forth in the KC United Registration Statement,
there were, as of April 3, 1996, 61,902,083 Shares outstanding and 62,061,588
Shares are expected to be outstanding immediately prior to the consummation of
the Offer and the Merger. Based on the foregoing, Western Resources believes
that the Minimum Tender Condition would be satisfied if at least an aggregate
of 55,855,430 Shares (or ninety percent (90%) of the Shares expected to be
outstanding immediately prior to the consummation of the Offer and the Merger)
had been validly tendered pursuant to the Offer and not withdrawn. Western
Resources reserves the right (but shall not be obligated), subject to the
rules and regulations of the Commission, to waive or amend the Minimum Tender
Condition and to purchase fewer than such number of Shares as would satisfy
the Minimum Tender Condition pursuant to the Offer; provided, however, that,
in the event of such waiver or amendment, the Offer shall expire no sooner
than ten business days from the date of such waiver or amendment.
 
  Western Resources Shareholder Approval Condition. Pursuant to the rules of
the NYSE (on which the Western Resources Common Stock is listed), the issuance
of Western Resources Common Stock pursuant to the Offer and the Merger must be
approved by the holders of a majority of the shares of Western Resources
Voting
 
                                      40
<PAGE>
 
Stock, voting as a single class, voted at a meeting of such holders at which
the total number of votes cast represents over 50% in interest of all shares
of Western Resources Voting Stock outstanding on the applicable record date.
In addition, pursuant to Western Resources' Amended and Restated Articles of
Incorporation (the "Western Resources Articles"), approval of (i) the holders
of a majority of the shares of Western Resources Voting Stock, voting as a
single class, to amend the Western Resources Articles to increase the number
of shares of Western Resources Common Stock authorized for issuance taking
into account the terms of the Offer and (ii) a majority of the Western
Resources preferred stock, par value $100 per share, 4 1/4% series, 4 1/2%
series and 5% series (the "Western Resources Preferred Stock") and together
with the Western Resources Common Stock, the "Western Resources Voting Stock")
voting as a single class, is required to approve the Merger. Western Resources
intends to seek such approvals at a special meeting of Western Resources'
shareholders (the "Western Resources Special Meeting").
 
  Missouri Control Share Acquisition Condition. The Missouri Control Share
Acquisition Condition may be satisfied by (i) the affirmative vote of (a) a
majority of all outstanding shares entitled to vote at a special meeting of
KCPL Shareholders voting by class if required by the terms of such shares, and
(b) a majority of all outstanding shares entitled to vote at such meeting
voting by class if required by the terms of such shares, excluding all
interested shares, in both cases approving the voting rights of the Shares to
be purchased pursuant to the Offer, (ii) the KCPL board of directors amending
the bylaws of KCPL (the "KCPL Bylaws") to provide that the Missouri Control
Share Acquisition Statute (as defined below) does not apply to the acquisition
of Shares pursuant to the Offer or (iii) Western Resources being satisfied, in
its sole discretion, that the provisions of the Control Share Acquisition
Statute do not in any way restrict Western Resources' ability to consummate
the Merger. For a summary of the Missouri Control Share Acquisition Statute,
see "Comparison of the Rights of Holders of Shares and Western Resources
Common Stock--Voting Rights in Connection with Mergers and Consolidations--
Missouri Control Share Acquisition Statute."
 
 
  Missouri Business Combination Condition. The Missouri Business Combination
Condition may be satisfied by the KCPL board of directors approving the Offer
for purposes of Section 351.459 prior to the consummation of the Offer. For a
summary of the Missouri Business Combination Statute, see "Comparison of the
Rights of Holders of Shares and Western Resources Common Stock--Voting Rights
in Connection with Mergers and Consolidations--Missouri Business Combination
Statute."
 
  The UtiliCorp/KCPL Merger Condition. One condition of the Offer is that
either (i) the KCPL Shareholders have voted on the approval and adoption of
the UtiliCorp/KCPL Merger Agreement and the Proposed UtiliCorp/KCPL
Transaction at a duly held meeting, and such merger agreement and merger have
not been approved and adopted by all requisite votes, (ii) a KCPL Shareholder
vote on such merger agreement and merger has not occurred and either a record
date for such a vote is not in effect or, if such a record date is in effect,
Western Resources is satisfied, in its sole discretion, that it will have full
voting rights as of such record date with respect to all Shares purchased by
it pursuant to the Offer or (iii) prior to the approval and adoption of the
UtiliCorp/KCPL Merger Agreement by the KCPL Shareholders, the KCPL board of
directors shall terminate the UtiliCorp/KCPL Merger Agreement in accordance
with its terms and without having breached such agreement. If the
UtiliCorp/KCPL Merger Agreement and the Proposed UtiliCorp/KCPL Transaction
are rejected by KCPL Shareholders at the Annual Meeting currently scheduled to
be held on May 22, 1996, or if the UtiliCorp/KCPL Merger Agreement is
terminated by the KCPL board of directors, this condition will be satisfied.
 
  Regulatory Approval Condition. Western Resources is subject as an operating
electric utility to the jurisdiction of the KCC and as a natural gas utility
to the jurisdiction of the KCC and the Corporation Commission of the State of
Oklahoma (the "OCC"), which have general regulatory authority over Western
Resources' rates, extensions and abandonments of service and facilities,
valuation of property, the classification of accounts, the acquisition of
securities of a competing utility and various other matters. Western Resources
is also subject to the jurisdiction of the KCC with respect to the issuance of
securities. There is no state regulatory body in Oklahoma having jurisdiction
over the issuance of Western Resources' securities.
 
                                      41
<PAGE>
 
   State and Local Public Utility Regulation. KCPL's 1995 Form 10-K indicates
 that KCPL is subject, as a public utility company, to the jurisdiction of the
 MPSC and the KCC with respect to, among other things, service and facilities,
 rates and charges, classification of accounts, valuations of property and
 various other matters.
 
   After the acquisition of Shares of KCPL and the Merger, Western Resources
 will be subject to the jurisdiction of the FERC, NRC, KCC, OCC and MPSC (the
 "Regulatory Commissions").
 
   Applications for approval, or waiver of approval, of the consummation of
 the Offer and the Merger and related transactions, including, in the case of
 certain commissions, the issuance of securities in connection therewith, have
 been or will be filed with the KCC, the MPSC and the OCC. On April 15, 1996,
 Western Resources filed its application for such approvals with the KCC.
 Western Resources intends to make applications after the date hereof to seek
 the required approvals of the Regulatory Commissions.
 
   Public Utility Holding Company Act. Western Resources is a "holding
 company" for purposes of the Public Utility Holding Company Act of 1935 (the
 "1935 Act") and is currently exempt from all provisions of the 1935 Act
 except Section 9(a)(2), which generally requires approval of the Commission
 prior to the direct or indirect acquisition of 5% or more of the voting
 securities of an electric or gas utility company by any person that already
 owns, directly or indirectly, 5% or more of the securities of a gas or
 electric utility company. KCPL is an electric utility company within the
 meaning of the 1935 Act, and exempt from all provisions of the 1935 Act
 except Section 9(a)(2). Western Resources anticipates that the Offer and the
 Merger will be consummated contemporaneously and that, consequently, no
 approval of the Commission under Section 9(a)(2) of the 1935 Act will be
 required for either the Offer or the Merger. Western Resources anticipates
 that, following consummation of the Offer and the Merger, it will continue to
 be exempt from all provisions of the 1935 Act except Section 9(a)(2).
 
   Federal Power Act. Section 203 of the Federal Power Act (the "FPA")
 provides that no public utility shall sell or otherwise dispose of its
 jurisdictional facilities or directly or indirectly merge or consolidate such
 facilities with those of any other person or acquire any security of any
 other public utility, without first having obtained authorization from the
 FERC. Thus, the approval of the FERC is required prior to consummation of the
 Offer and the Merger. Accordingly, Western Resources intends to file a FERC
 application requesting that FERC approve the acquisition of the Shares
 pursuant to the Offer and the Merger and the disposition of KCPL's
 jurisdictional facilities under (S) 203 of the FPA.
 
   Antitrust. Under the Hart-Scott-Rodino Antitrust Improvements Act of 1976,
 as amended (the "HSR Act") and the rules (the "Rules") that have been
 promulgated thereunder, certain acquisition transactions may not be
 consummated unless certain information has been furnished to the Antitrust
 Division of the Department of Justice (the "Antitrust Division") and the FTC
 and certain waiting period requirements have been satisfied. The acquisition
 of Shares pursuant to the Offer is subject to the HSR Act.
 
   Western Resources intends to file with the Antitrust Division and the
 Federal Trade Commission (the "FTC") a Hart-Scott-Rodino Notification and
 Report Form with respect to the Offer. Under the applicable provisions of the
 HSR Act, the purchase of Shares under the Offer could not be consummated
 until the expiration of a 30-day waiting period following the filing of such
 Form by Western Resources.
 
   Federal and state antitrust enforcement agencies frequently scrutinize
 under the antitrust laws transactions such as Western Resources' acquisition
 of Shares pursuant to the Offer. At any time before or after Western
 Resources' acquisition of Shares, any such agency could take such action
 under the antitrust laws as it deems necessary or desirable in the public
 interest, including seeking to enjoin the acquisition of Shares pursuant to
 the Offer or otherwise or seeking divestiture of Shares acquired by Western
 Resources or divestiture of substantial assets of Western Resources and/or
 KCPL. Private parties may also bring legal action under the antitrust laws
 under certain circumstances.
 
   Based upon an examination of publicly available information relating to the
 businesses in which both Western Resources and KCPL are engaged, Western
 Resources believes that the Offer will not violate the
 
                                      42
<PAGE>
 
 antitrust laws. Nevertheless, there can be no assurance that a challenge to
 the Offer on antitrust grounds will not be made or that, if such a challenge
 is made, Western Resources will prevail. See "The Offer--Conditions of the
 Offer."
 
   Atomic Energy Act. Section 184 of the Atomic Energy Act of 1954, as amended
 (the "AEA"), provides that no person may transfer or assign a license or any
 rights thereunder, either directly or indirectly, without first having
 obtained authorization from the NRC. Based upon information contained in the
 KC United Registration Statement, KCPL holds an interest in an NRC license
 (the "NRC Possession License") in connection with the ownership of an
 interest in Wolf Creek. KCPL is also a partial owner of WCNOC, which holds an
 NRC license (the "NRC Operating License") in connection with the operation of
 Wolf Creek. KGE also holds interests in the same licenses in connection with
 KGE's ownership of an interest in Wolf Creek and WCNOC. The approval of the
 NRC will be required prior to consummation of the Offer and the Merger.
 Accordingly, Western Resources has notified the NRC of the Offer and will
 request the approval of the Offer and the Merger and the transfer of the NRC
 Possession License and NRC Operating License under (S) 184 of the AEA.
 
   Other. Based upon the KC United Registration Statement, Western Resources
 is aware that KCPL possesses municipal franchises and environmental permits
 and licenses that may require the consent of the licensor to the consummation
 of the Offer and the Merger or may need to be renewed, replaced or
 transferred as a result of the Offer and Merger. Western Resources does not
 anticipate any difficulties at the present time in obtaining such consents,
 renewals, replacements or transfers.
 
   General. Except as set forth above, based upon an examination of publicly
 available information filed by KCPL with the Commission and other publicly
 available information with respect to KCPL, Western Resources is not aware of
 (a) any license or regulatory permit which appears to be material to the
 business of KCPL and its subsidiaries, taken as a whole, and which is likely
 to be adversely affected by Western Resources' acquisition of Shares pursuant
 to the Offer or the Merger or (b) any approval or other action by any state,
 federal or foreign governmental administrative or regulatory agency or
 authority that would be required prior to the acquisition of Shares pursuant
 to the Offer or the Merger. Western Resources presently intends to take such
 actions with respect to any approvals as will enable it to acquire the Shares
 and consummate the Merger. In this regard, Western Resources expressly
 reserves the right to challenge the validity and applicability of any state,
 foreign or other statutes or regulations purporting to require approval of
 the commencement or consummation of the Offer and the Merger.
 
   There can be no assurance that any license, permit, approval or other
 action, if needed, would be obtained, or would be obtained without
 substantial conditions, or, if so obtained, when it would be obtained, or
 that adverse consequences might not result to KCPL, Western Resources or to
 their respective businesses in the event of adverse regulatory action or
 inaction. Western Resources' obligation under the Offer to accept for
 exchange and exchange Shares is subject to the obtaining of all requisite
 regulatory approvals as well as the satisfaction of other conditions which
 could be triggered by an adverse regulatory development. See "The Offer--
 Conditions of the Offer."
 
   THE OFFER IS CONDITIONED UPON, AMONG OTHER THINGS, WESTERN RESOURCES HAVING
 RECEIVED ALL NECESSARY OR DESIRABLE GOVERNMENTAL AND REGULATORY APPROVALS AND
 CONSENTS FOR THE ACQUISITION OF SHARES PURSUANT TO THE OFFER AND FOR
 CONSUMMATION OF THE MERGER AND THE OTHER TRANSACTIONS CONTEMPLATED HEREIN,
 INCLUDING APPROVALS AND CONSENTS FROM THE REGULATORY COMMISSIONS AND SUCH
 APPROVALS AND CONSENTS HAVING BECOME FINAL ORDERS AND SUCH FINAL ORDERS NOT
 HAVING IMPOSED TERMS OR CONDITIONS WHICH, IN THE AGGREGATE, WOULD HAVE OR,
 INSOFAR AS REASONABLY CAN BE FORESEEN, COULD HAVE A MATERIAL ADVERSE EFFECT
 ON THE BUSINESS, ASSETS, FINANCIAL CONDITION, OR RESULTS OF OPERATIONS OF
 WESTERN RESOURCES, KCPL AND THEIR RESPECTIVE SUBSIDIARIES TAKEN AS A WHOLE.
 SEE "THE OFFER--CONDITIONS OF THE OFFER."
 
  Pooling Condition. The consummation of the Offer and the Merger is
conditioned upon, among other things, the receipt by Western Resources of a
letter from its independent accountants stating that the Merger will
 
                                      43
<PAGE>
 
qualify as a pooling of interests transaction under generally accepted
accounting principles and applicable Commission regulations. Based upon the
information currently available to it, Western Resources believes that the
combination of Western Resources and KCPL pursuant to the Offer and the Merger
will qualify for pooling of interests treatment under applicable accounting
rules and regulations.
 
  Short Form Merger Condition. The consummation of the Offer is conditioned
upon, among other things, Western Resources being satisfied, in its sole
discretion, that the provisions of Section 351.447 of the MGBCL and Section
17-6703 of the KGCC do not require the vote of any shareholder of either
Western Resources or KCPL unless such vote has been obtained prior to the
consummation of the Offer. Pursuant to the terms of each statute, Western
Resources must own 90% of each class of stock of KCPL to consummate a short-
form merger under Section 17-6703. It is a condition to the Offer that all
outstanding shares of KCPL Preferred Stock be redeemed. In addition to the
foregoing, under the Western Resources Articles, the holders of Western
Resources Preferred Stock, voting as a single class is required to approve a
merger consummated under Section 351.447 and Section 17-6703. Western
Resources intends to seek such approval at the Western Resources Special
Meeting.
 
  KCPL Preferred Stock Redemption Condition. The Offer is conditioned upon,
among other things, all outstanding Shares of KCPL Preferred Stock having been
redeemed prior to consummation of the Offer. This condition is substantially
the same as that provided for in the UtiliCorp/KCPL Merger Agreement. The
satisfaction of this condition will require the cooperation of the KCPL board
of directors.
 
  Certain Other Conditions of the Offer. Notwithstanding any other provision
of the Offer and subject to any applicable rules and regulations of the
Commission, including Rule 14e-1(c) under the Exchange Act (relating to
Western Resources' obligation to pay for or return tendered Shares promptly
after the termination or withdrawal of the Offer), Western Resources shall not
be required to accept for exchange or exchange any Shares, may postpone the
acceptance for exchange of or exchange for tendered Shares, and may, in its
sole discretion, terminate or amend the Offer as to any Shares not then
exchanged for tender if at the Expiration Date, any of the Offer Conditions
have not been satisfied or waived or if on or after the date of this
Prospectus and at or prior to the time of exchange of any such Shares (whether
or not any Shares have theretofore been accepted for exchange or exchanged
pursuant to the Offer), any of the following events shall not have occurred:
 
    (a) The shares of Western Resources Common Stock which shall be issued to
  the KCPL Shareholders in the Offer and the Merger shall have been
  authorized for listing on the NYSE, subject to official notice of issuance.
 
    (b) The Registration Statement shall have become effective under the
  Securities Act, and no stop order suspending the effectiveness of the
  Registration Statement shall have been issued and no proceedings for that
  purpose shall have been initiated or threatened by the Commission.
 
    (c) No order, injunction or decree issued by any court or agency of
  competent jurisdiction or other legal restraint or prohibition preventing
  the consummation of the Offer and/or the Merger or any of the other
  transactions contemplated by this Prospectus shall be in effect. No
  statute, rule, regulation, order, injunction or decree shall have been
  enacted, entered, promulgated or enforced by any court, administrative
  agency or commission or other governmental authority or instrumentality
  which prohibits, restricts or makes illegal the consummation of the Offer
  and/or the Merger.
 
    (d) All required material governmental authorizations, permits, consents,
  orders or approvals which do not impose terms or conditions that could
  reasonably be expected to have a material adverse effect on Western
  Resources and/or KCPL have been received.
 
    (e) (i) The representations and warranties of KCPL in the UtiliCorp/KCPL
  Merger Agreement with respect to capitalization, authority, financial
  statements, and absence of certain changes or events shall be true and
  correct in all material respects as of the date of this Prospectus and
  (except to the extent such representations and warranties speak as of an
  earlier date) as of the Expiration Date as though made on and as of the
  Expiration Date and (ii) the representations and warranties of KCPL set
  forth in the UtiliCorp/KCPL Merger Agreement other than those specifically
  enumerated in clause (i) hereof shall be
 
                                      44
<PAGE>
 
  true and correct in all respects as of the date of this Prospectus and
  (except to the extent such representations and warranties speak as of an
  earlier date) as of the Expiration Date as though made on and as of the
  Expiration Date; provided, however, that for purposes of determining the
  satisfaction of the condition contained in this clause (ii), no effect
  shall be given to any exception in such representations and warranties
  relating to materiality or a Material Adverse Effect (as defined in the
  UtiliCorp/KCPL Merger Agreement), and provided, further, however, that, for
  purposes of this clause (ii), such representations and warranties shall be
  deemed to be true and correct in all respects unless the failure or
  failures of such representations and warranties to be so true and correct,
  individually or in the aggregate, results or would reasonably be expected
  to result in a material adverse effect on KCPL and its subsidiaries taken
  as a whole.
 
  The foregoing conditions are for the sole benefit of Western Resources and
may be asserted by Western Resources regardless of the circumstances giving
rise to any such conditions (including any action or inaction by Western
Resources) or may be waived by Western Resources in whole or in part (other
than the Western Resources Shareholder Approval Condition, the Regulatory
Approval Condition and the condition relating to effectiveness of the
Registration Statement). Although Western Resources reserves the right to do
so, Western Resources does not currently intend to waive any Offer Condition
unless it determines that doing so would not prevent it from consummating the
Merger promptly after consummating the Offer. The determination as to whether
any condition has been satisfied shall be in the sole judgment of Western
Resources and will be final and binding on all parties. The failure by Western
Resources at any time to exercise any of the foregoing rights shall not be
deemed a waiver of any such right and each such right shall be deemed a
continuing right which may be asserted at any time and from time to time.
Notwithstanding the fact that Western Resources reserves the right to assert
the failure of a condition following acceptance for payment but prior to
payment in order to delay payment or cancel its obligation to exchange
properly tendered Shares, Western Resources will either promptly exchange such
Shares or promptly return such Shares.
 
FEES AND EXPENSES
 
  Western Resources has retained Georgeson & Company, Inc. ("Georgeson") to
act as Information Agent in connection with the Offer. The Information Agent
may contact holders of Shares by mail, telephone, telex, telegraph and
personal interviews and may request brokers, dealers and other nominee
stockholders to forward the Offer materials to beneficial owners of Shares.
The Information Agent will receive a fee estimated not to exceed $150,000 for
such services, plus reimbursement of out-of-pocket expenses, and Western
Resources will indemnify the Information Agent against certain liabilities and
expenses in connection with the Offer, including liabilities under federal
securities laws.
 
  Pursuant to a letter agreement dated September 5, 1995, as amended (the
"Letter Agreement"), Salomon Brothers Inc ("Salomon") is providing certain
financial advisory services to Western Resources in connection with the Offer.
Under the Letter Agreement, Western Resources has agreed to pay Salomon for
its financial advisory services (including its services as Dealer Manager) in
connection with the Western Resources Offer, a financial advisory fee of (i)
$400,000 upon execution of the Letter Agreement (ii) $500,000 upon public
announcement of the Offer, and (iii) up to an additional $6,000,000 (less
amounts paid or payable described in (ii) above) upon Western Resources'
acquisition of more than 20% of the outstanding Shares of KCPL or upon the
consummation of the Merger. Western Resources has also agreed to reimburse
Salomon for its reasonable out-of-pocket expenses, including the fees and
expenses of its legal counsel, incurred in connection with its engagement, and
has agreed to indemnify each of Salomon and certain related persons and
entities against certain liabilities and expenses in connection with Salomon's
engagement, including certain liabilities under the federal securities laws.
In connection with Salomon's engagement as financial advisor, Western
Resources anticipates that certain employees of Salomon may communicate in
person, by telephone or otherwise with a limited number of institutions,
brokers or other persons who are KCPL Shareholders for the purpose of
assisting in the Proxy Solicitation. Salomon will not receive any fee for or
in connection with such solicitation activities by its employees apart from
the fees it is otherwise entitled to receive as described above.
 
                                      45
<PAGE>
 
  In addition to the fees to be received by Salomon in connection with its
engagement as financial advisor to Western Resources, Salomon has in the past
rendered various investment banking and financial advisory services for
Western Resources for which it has received customary compensation.
 
  Western Resources will pay the Exchange Agent reasonable and customary
compensation for its services in connection with the Offer, plus reimbursement
for out-of-pocket expenses, and will indemnify the Exchange Agent against
certain liabilities and expenses in connection therewith, including
liabilities under the federal securities laws. Western Resources will not pay
any fees or commissions to any broker or dealer or other person (other than
the Dealer Manager and the Information Agent) for soliciting tenders of Shares
pursuant to the Offer. Brokers, dealers, commercial banks and trust companies
will be reimbursed by Western Resources for customary mailing and handling
expenses incurred by them in forwarding material to their customers.
 
ACCOUNTING TREATMENT
 
  Western Resources believes that the Merger will qualify as a "pooling of
interests" for accounting and financial reporting purposes, based upon their
review and the advice of Arthur Andersen LLP, their independent public
accountants. Under this method of accounting, Western Resources will restate
its consolidated financial statements to include the assets, liabilities,
shareholders' equity and results of operations of KCPL. It is anticipated that
upon consummation of the Merger, the fiscal year of the combined company will
be the calendar year.
 
STOCK EXCHANGE LISTING
 
  The Western Resources Common Stock is listed on the NYSE. Application will
be made to list the Western Resources Common Stock to be issued pursuant to
the Offer and the Merger on the NYSE. As described above under "The Offer--
Conditions of the Offer--Western Resources Shareholder Approval Condition,"
pursuant to the rules of the NYSE, the issuance of Western Resources Common
Stock in the Offer and the Merger must be approved by the holders of a
majority of the shares of Western Resources Voting Stock, voting as a single
class, voted at a meeting of such holders at which the total number of votes
cast represents over 50% in interest of all shares of Western Resources Voting
Stock outstanding on the applicable record date.
 
             MATERIAL CONTACTS BETWEEN KCPL AND WESTERN RESOURCES
 
  KGE, a wholly owned subsidiary of Western Resources, is the joint owner with
KCPL or lessee in an operating lease with a third party of the LaCygne Station
(a coal-fired station consisting of two generating units aggregating
approximately 1,344 MW capacity) and Wolf Creek (a nuclear powered generating
station of approximately 1,166 MW capacity). Western Resources, KGE and KCPL
are members of the MOKAN and Southwest Power Pools and in the normal course of
business make purchases and sales of power to each other and enter into other
agreements or arrangements with respect to their business operations.
 
  KCPL has been and is the operator of LaCygne Station and has billed KGE for
its share of capital additions, fuel costs and other operating expenses. KGE
and KCPL are parties to a variety of contracts relating to the operations and
maintenance of LaCygne Station. Since 1992 such expenses have been as follows:

  In 1981 KCPL, KGE and Kansas Electric Power Cooperative, Inc., a group of
approximately 25 electric cooperatives ("KEPCo"), signed an Ownership
Agreement with respect to Wolf Creek providing for undivided ownership shares
of 47%, 47% and 6%, respectively. Wolf Creek was completed in 1985. In 1986,
the joint

owners organized WCNOC and entered into an Operating Agreement with WCNOC,
which operates, maintains, repairs, decontaminates and decommissions Wolf
Creek as provided in the Operating Agreement. The license to operate Wolf
Creek was transferred to WCNOC effective January 1, 1987. WCNOC invoices each
of the joint owners for their respective shares of all expenses for operating
and maintaining, and for capital addition to Wolf Creek. Total operating
expenses related to WCNOC for its share of capital additions, fuel costs and
other operating and maintenance expenses since 1992 are as follows:

  From time to time WCNOC may generate an "owner work order" pursuant to which
one of the three owners contracts to provide a specific service to WCNOC for
which that owner is paid by WCNOC; the amount of such billing is then
reallocated to the joint owners in accordance with their ownership shares.
 
  Pursuant to an October 1, 1984 Lease Agreement, as amended, KCPL leases
KGE's 345 kv transmission line from Wolf Creek to LaCygne Station. The rent
paid by KCPL to KGE since 1992 for the use of the transmission line is as

          NOTES TO UNAUDITED PRO FORMA COMBINED FINANCIAL STATEMENTS
 
  The unaudited pro forma combined balance sheet and combined statement of
income are presented as if the Merger had been effective for all periods
presented. Terms of the Offer allow holders of Shares to exchange each Share
held for $28 worth of Western Resources Common Stock, subject to certain
limitations as set forth herein. Pro Forma shares and related earnings and
dividends per share information has been calculated assuming an exchange ratio
of .93333 based on April 19, 1996 closing stock prices (the last trading day
before the date of this Preliminary Prospectus).
 
  The Merger is assumed to generate substantial cost savings. The assumed cost
savings, effects of the Regulatory Plan and transaction costs have not been
reflected in the pro forma combined balance sheets and combined statements of
income. Transaction costs including fees for advisors, attorneys and other
consultants and incremental direct costs of completing the Merger are
estimated to approximate $88 million.
 
  There are no anticipated changes in either Western Resources' or KCPL's
accounting policies as a result of the Merger. Both companies accrue unbilled
revenue for energy delivered at the end of each reporting period, use
composite depreciation methods at group rates specified pursuant to regulation
and have certain other accounting policies which differ due to the nature of
how regulators have allowed certain costs to be recovered from customers.
 
  KGE is the joint owner with KCPL or lessee under an operating lease with a
third party of the LaCygne Station and Wolf Creek. These generating facilities
represent approximately 23% of Western Resources' total generating capacity,
39% of KCPL's total generating capacity, and 29% of the combined company's
total generating capacity. See "Material Contracts Between KCPL and Western
Resources."

                      UNAUDITED FORECASTED FINANCIAL DATA
 
  The forecast was prepared to reflect the pro forma results of operations for
the pre-Merger periods of 1996 and 1997 and the combined company post-Merger
results of operations for the periods 1998 through 2000. The Merger is assumed
to be consummated on January 1, 1998 and to be accounted for as a pooling of
interests.
 
  The forecast was developed solely by Western Resources from the stand-alone
forecast of Western Resources and, for KCPL, a forecast based on public
information, analysts' forecasts, knowledge of cost trends associated with
generating units jointly owned by Western Resources and KCPL, and Western
Resources' knowledge of the electric utility industry. To the best knowledge
and belief of Western Resources, the assumptions contained within the forecast
are reasonable. The assumptions disclosed herein are those which are
significant to the forecast.
 
  This forecasted financial information involves significant judgments and
assumptions which may not be realized and are inherently subject to
significant uncertainties, all of which are difficult to predict and many of
which are beyond the control of Western Resources. Accordingly, there can be
no assurance this forecast will be realized and actual results may vary
materially from those shown. Selected significant assumptions to the
forecasted financial data are described in "Prospectus Summary--Selected
Unaudited Forecasted Financial Data--Summary of Selected Significant
Assumptions" and in "Notes to Unaudited Forecasted Statement of Income."
 
  Western Resources as a matter of course does not publicly disclose
forecasted financial statements. The principal assumptions underlying the
forecast are the terms of the Offer and the Regulatory Plan. See "Background
of the Offer--Comparison of the Proposals--Regulatory Approvals" and "The
Offer." The assumptions underlying the forecast also involve judgments with
respect to, among other things, expected cost savings from the Merger, normal
weather conditions, future national and regional economic and competitive
conditions, inflation rates, regulatory treatment, future financial market
conditions, interest rates and future business decisions, which, though
considered reasonable by Western Resources, may not be realized. Additionally,
the forecast is inherently subject to significant weather, regulatory,
business, economic and competitive uncertainties, all of which are difficult
to predict and many of which are beyond the control of Western Resources;
accordingly, there can be no assurance that the forecast will be realized, and
actual results and subsequent forecasts, if any, may vary materially from
those shown. In light of the uncertainties inherent in forecasts of any kind,
the inclusion of the forecast herein should not be regarded as a
representation by Western Resources or any other person that the forecast will
be achieved. Shareholders and other investors are cautioned not to place undue
reliance on the forecast.
 
  Accordingly, the forecast reflects management's judgment as of April 14,
1996, the date of this forecast, of the expected conditions and its expected
course of action. There will be differences between forecasted and actual
results, because events and circumstances frequently do not occur as expected,
and those differences may be material.
 
  The forecasted financial data has not been audited, compiled or otherwise
examined by any independent certified public accountant. The forecasted data
for KCPL has not been obtained from or reviewed by the management of KCPL. The
forecast was not prepared with a view to compliance with the published
guidelines established by the American Institute of Certified Public
Accountants for preparation and presentation of financial forecast.
 
  Western Resources does not intend to update or otherwise revise the forecast
to reflect circumstances existing after the date of the forecast or to reflect
the occurrence of unanticipated events. The forecast should be read together
with the information contained in "Prospectus Summary" and "Western Resources
and KCPL Unaudited Pro Forma Combined Financial Information" included
elsewhere in this Prospectus and in conjunction with the historical financial
statements and notes thereto contained in the Western Resources' 1995 Form 10-
K and KCPL 1995 Form 10-K, both incorporated by reference herein.

               NOTES TO UNAUDITED FORECASTED STATEMENT OF INCOME
 
  The discussion which follows summarizes significant assumptions used in the
development of the forecasted Statements of Income for 1996 through 2000.
These assumptions were developed solely by Western Resources. The information
used by Western Resources to forecast amounts for KCPL is limited to publicly
available information, analyst's forecasts, knowledge of cost trends
associated with jointly owned generating facilities Western Resources has with
KCPL and Western Resources' knowledge of the electric utility industry. KCPL
has not participated in the development of the forecasted Statements of Income
for 1996 through 2000 or reviewed this information. The significant
assumptions are set forth below.
 
MERGER ASSUMPTIONS
 
  General. Pursuant to the Offer, each Share is entitled to $28 worth of
Western Resources Common Stock, subject to certain limitations. See "The
Offer." The Merger is assumed to result in lower operating costs due to the
achievement of cost savings resulting from the Merger and Regulatory Plan. See
"Background of the Offer--Comparison of the Proposals."
 
  Stock Exchange. The forecast assumes each Share is exchanged for .96137
shares of Western Resources Common Stock assuming common stock closing prices
as of April 12, 1996 (the last trading day before public announcement of the
April 14 Offer). The forecast assumes the Merger is accounted for as a pooling
of interests. Under this method, the recorded account balances of Western
Resources and KCPL are carried forward to a combined total at their recorded
amounts. The income includes the combined income of Western Resources and KCPL
as though the Merger occurred at the beginning of the accounting period. Prior
periods are restated to present the combined operating results and financial
position.
 
  Dividends. The forecasted dividends are consistent with Western Resources'
past practice. This practice is assumed for purposes of the forecast to be
continued subsequent to the Merger.
 
  Merger-Related Regulatory Assumptions. The forecast assumes all regulatory
approvals required to consummate the Merger will be obtained by December 31,
1997. As proposed in the application of Western Resources to the KCC, the
forecast assumes retail rates for KGE and KCPL customers will be reduced in
accordance with the Regulatory Plan. See "Background of the Offer--Comparison
of the Proposals--Regulatory Plan."
 
  Transaction Costs. Transaction costs associated with the Merger are
estimated to be approximately $88 million and are expensed upon consummating
the Merger in 1998. This nonrecurring expense is estimated to reduce earnings
by approximately $0.69 per share in 1998. The transaction costs represent
professional fees for attorneys, investment bankers, accountants and other
advisors and other direct incremental costs.
 
  Cost Savings. Cost Savings assumed in development of the forecast for the
combined company have been limited to quantifiable cost savings which are
estimated upon the combination of Western Resources and KCPL. Recognition has
been given to the costs to be incurred in achieving these potential savings
and to the time required to implement plans designed to lower costs. See
"Background of the Offer--Comparison of the Proposals."
 
 
                                      57
<PAGE>
 
  The total cost savings, net of the costs necessary to achieve these
reductions, are estimated to be approximately $43.3 million in 1998, $76.8
million in 1999, $93.8 million in 2000 and cumulatively $1.043 billion during
the first ten years following the Merger. The savings in 1998 and 1999 are
lower than any subsequent year's savings due to the costs to achieve and
phase-in of certain cost savings. A summary of the cost savings beginning

</TABLE>
 
  The forecasted amounts have been adjusted to consider the effect on
operating results from savings of capital costs such as capacity deferrals and
purchasing economies.
 
OPERATING ASSUMPTIONS
 
  Electric Revenues. Electric rates for the merged company will continue to be
subject to approval by the KCC at the retail level for Kansas jurisdictional
customers and the MPSC for Missouri jurisdictional customers and the FERC at
the wholesale level. Although both the wholesale and retail markets are
becoming increasingly competitive and subject to deregulation, these forecasts
do not assume any significant change to the structure of electric utility
regulation.
 
    KPL Electric. The forecast assumes KPL electric service territory will
  sustain continued growth in sales from electric operations at a compound
  annual growth rate of 2.7% over the forecast period.
 
                                      58
<PAGE>
 
    KGE Electric. The forecast assumes KGE's electric service territory will
  sustain continued growth in electric sales at a compound annual growth rate
  of 2.3% over the forecast period.
 
    KCPL Electric. The forecast assumes KCPL's electric service territory
  will sustain continued growth in electric sales at a compound annual growth
  rate of 2.5% over the forecast period.
 
  The forecast also assumes normal weather conditions. Sales distribution by
customer class is expected to remain relatively constant and reflect the
existing mix of customers within the service territories of each KPL, KGE and
KCPL. Forecasted revenues reflect the rate reductions in Regulatory Plan.
 
  Natural Gas Revenues. Natural gas rates are assumed to continue to be
subject to approval by the KCC and the OCC at the retail level. Although
recent FERC decisions and market conditions have created substantial change
within the natural gas business, this forecast does not assume any significant
changes in the current structure of natural gas regulation.
 
  The forecast assumes the natural gas service territory will experience
modest growth in natural gas sales. Revenue from continuing gas operations is
assumed to increase at a compound annual growth rate of approximately 6.9%
during the forecast periods taking into consideration increased purchased gas
costs passed on to customers through a purchased gas adjustment clause
("PGA"). The forecasted revenues also include increases to the rates charged
reflecting the gas rate increase authorized by the KCC in April 1996 and an
additional increase in 1998 which is assumed to be needed to recover revenue
requirements associated with the additional capital investment and operating
expenses related to Western Resources' gas service line replacement program.
The distribution of gas sales among customer classes remains relatively
constant over the forecast periods, with each class maintaining its relative
proportion of total sales, including transportation customers.
 
  Western Resources has been authorized in Kansas and Oklahoma to maintain a
PGA provision in its rates. The PGA allows Western Resources to pass on to its
customers the actual costs associated with purchases of natural gas, thereby
removing Western Resources' potential exposure associated with fluctuations in
the natural gas market. During the forecast period, a significant portion of
the anticipated revenue increase is associated with increased gas purchase
costs and has no impact on forecasted earnings.
 
  Regulatory Assumptions. The forecast assumes the accounting for regulated
enterprises prescribed by Statement of Financial Accounting Standards No. 71,
"Accounting for the Effects of Certain Types of Regulations" (SFAS 71),
continues to be applicable for all periods presented. SFAS 71 requires
deferral of certain costs and obligations based upon approvals received from
regulators to permit recovery or require refund of these costs and revenues in
future periods. Consequently, the recorded net book value of certain assets
and liabilities may be different than would otherwise be recorded by
unregulated enterprises. Although recent developments suggest the electric
generation industry may become more competitive, the degree to which
regulatory oversight will be lifted and competition permitted is uncertain.
 
  Fuel. KPL, KGE and KCPL rates do not provide for fuel adjustment clauses
within their respective retail rate structures.
 
    KPL. In 1996, predominantly all of KPL's electric energy was generated
  using low-sulfur coal, with the remainder generated using natural gas or
  fuel oil. This fuel mix pattern is expected to continue throughout the
  forecast periods.
 
    KGE. KGE generates electricity using a variety of fuels, including
  uranium, coal, natural gas and fuel oil. Currently, KGE has on hand or
  under contract 75% of the uranium required through the year 2003 for Wolf
  Creek. The balance is expected to be obtained through spot market or
  contract purchases. Unlike the cost of coal or other conventional fuels,
  the cost of uranium is recorded as a plant asset at the time of purchase,
  enrichment and fabrication, and is amortized to expense when used based
  upon the quantity of heat produced for the generation of electricity. Most
  of KGE's coal requirements are low-sulfur Wyoming coal purchased under
  long-term contracts.
 
 
                                      59
<PAGE>
 
    KCPL. Forecasted fuel costs have been estimated based upon historical
  trends. KCPL generates electricity primarily using coal and uranium as fuel
  sources.
 
  Natural Gas Purchases. Western Resources purchases natural gas from a
combination of interstate pipelines and direct wellhead production on both the
spot market and under long-term contracts. Approximately 80% of Western
Resources' gas purchases are from nonaffiliated interstate pipeline companies.
These contracts vary in length from one to twenty years.
 
  Operations and Maintenance. The cost savings estimated with the Merger are
assumed to be realized beginning in 1998. The forecasted savings are estimated
to reduce amounts classified as operations and maintenance expenses by $35
million in 1998, $64 million in 1999 and $70 million in 2000. See additional
details regarding cost savings listed under the Merger assumptions section of
this forecast.
 
  The forecast assumes an annual increase for operations and maintenance
expense of approximately 3.4%, based on economic projections for inflation.
The costs increased by this factor, however, do not include nuclear refueling
or La Cygne operating lease expenses. Nuclear refueling costs have been
included approximately every 18 months and are forecasted to occur in
accordance with Wolf Creek's normal refueling cycle. The operating lease
expense for the La Cygne Unit 2 is the result of KGE's sale-leaseback of that
plant. The operating lease expense, net of the amortization of the gain on the
sale, increases in 1997 from $22.5 million annually to $28.9 million annually
under provisions of the operating lease agreement.
 
  Depreciation. For financial reporting purposes, Western Resources and KCPL
both use the straight-line method to depreciate the original cost of property
over the estimated remaining service life. The depreciation rates used during
the forecast periods are consistent with those currently in effect and
approximate 3%, except as modified by the Regulatory Plan. In accordance with
this Regulatory Plan, depreciation of Wolf Creek has been accelerated by $50
million annually. This reduction will bring the estimated combined net book
value of Wolf Creek from about $1,870 per KW at December 31, 1995, to
approximately $740 per KW by the year 2007 (ten years following the Merger).
 
  Decommissioning. Decommissioning costs are assumed to be recovered from
customers over the life of Wolf Creek. These costs are based on estimated
unrecovered decommissioning costs, which consider inflation over the remaining
estimated life of Wolf Creek and are net of earnings on amounts recovered from
customers and deposited in an external trust fund.
 
  General Taxes. General taxes include such items as ad valorem taxes, payroll
taxes, and other miscellaneous taxes. The forecast assumes these taxes
increase as a direct result of items such as property additions, increased
wages and revenues.
 
  Income Taxes. The following income tax assumptions have been made in
developing the forecast.
 
  . Income tax expense includes provisions for income taxes currently payable
    and deferred income taxes. Income taxes include both federal and state
    income taxes, and are developed based upon each year's level of
    forecasted taxable income.
 
  . Forecasted income tax provisions have been adjusted for permanent and
    "flow-through" items to account for differences between the forecasted
    effective income tax rate and the applied statutory income tax rate. The
    principal difference between the statutory federal income tax rate and
    the effective income tax rate are state income taxes, non-taxable income,
    net tax benefits flowed through pursuant to regulatory orders and
    amortization of investment tax credits.
 
  . The combined effective income tax rate is forecasted to be approximately
    36%, 36%, 43%, 35% and 35% in 1996, 1997, 1998, 1999 and 2000,
    respectively.
 
 
                                      60

  Financing Assumptions. The forecast considers the following assumptions for
financing for 1996 through 2000:
 
    Short-Term Debt. Short-term debt is used to initially finance capital
  expenditures and meet other working capital requirements. The financing
  provided by short-term debt is assumed to bear an interest rate of 6%.
  During the forecast period, short-term debt is refinanced to long-term debt
  in the amount of $500 million in 1998.
 
    Common Stock. During the forecast period common stock is only issued to
  meet normal operational financing requirements. This includes shares issued
  under Western Resources' dividend reinvestment plan, providing
  approximately $27 million in 1996, $29 million in 1997 and $31 million in
  1998. In addition the forecast assumes Western Resources issues
  approximately $80 million to finance investments in international energy
  projects.
 
    Preferred and Preference Stock. The forecast assumes Western Resources
  redeems $150 million of preference stock in 1996 and 1997. In addition, the
  forecast assumes the redemption of KCPL's preferred stock.
 
    Quarterly Income Debt Securities (QUIDS). The forecast assumes Western
  Resources issues $170 million of QUIDS in 1996 and 1997 at an interest rate
  of 7.75%.
 
    Long-Term Debt. The forecast assumes long-term debt is issued only to
  refinance short-term debt used to meet operational financing requirements.
  Long-term debt retirements are made only to meet scheduled maturities of
  long-term debt.
 
    Securities Covenants. All covenants of debt and preferred stock are
  maintained in the forecast period.
 
  Other Income and Deductions. The following assumptions have been made in
developing forecasts for other income and deductions:
 
  . Western Resources owns 100% of several non-regulated subsidiaries. These
    include Westar Capital, Westar Business Services, Westar Consumer
    Services and The Wing Group. In addition, Western Resources owns a 23.9%
    interest in ADT and an equity interest in a gas compression company.
    Increases in other income during the forecast period are largely
    comprised of earnings from investments in electronic security services
    and the development of certain international independent power projects.
    See "Business of Western Resources."
 
  . KCPL's non-regulated business units have not been forecasted to generate
    any material amounts of earnings during the forecast period.
 
  . The forecast includes projected borrowings against the cash value and the
    costs associated with premium and interest payments on corporate owned
    life insurance ("COLI") policies, net of income due to increases in cash
    surrender value.
 
  . The forecast assumes Western Resources will continue its program of
    deferring post-retirement and post-employment costs determined on the
    accrual basis in accordance with SFAS 106 and SFAS 112, and netting those
    costs against an income stream generated by investments in COLI under
    provisions of current regulatory practices. In the event that the income
    stream of COLI is reduced or eliminated by pending national tax
    legislation, the forecast assumes incremental SFAS 106 and SFAS 112
    expense will be recovered in rates approved by the KCC.
 
  . Forecasted amounts for other income and deductions also include other
    smaller items of income and deductions, net of income tax effects, not
    included in the rate regulated revenues. A pre-tax gain of approximately
    $20 million in 1997 is assumed from selling certain immaterial non-
    strategic assets.

                DESCRIPTION OF WESTERN RESOURCES' CAPITAL STOCK
 
  The amount of authorized capital stock of Western Resources consists of
85,000,000 shares of Western Resources Common Stock, par value $5.00 per
share, 4,000,000 shares are Western Resources preference stock without par
value (the "Western Resources Preference Stock"), 600,000 shares are Western
Resources Preferred Stock, par value $100.00 per share (the "Par Value
Preferred Stock") and 6,000,000 shares of preferred stock without par value
(the "No Par Value Preferred Stock"). The Par Value Preferred Stock and the No
Par Value Preferred Stock are referred to herein together as the "Western
Resources Preferred Stock".
 
WESTERN RESOURCES COMMON STOCK
 
  As of April 15, 1996, Western Resources had 63,407,872 shares of Western
Resources Common Stock issued and outstanding. The holders of Western
Resources Common Stock and the Preferred Stock, voting as one class, are
entitled to one vote per share on all matters requiring stockholder action
(except for the election of directors) subject to the special voting rights of
holders of Western Resources Preferred Stock and Western Resources Preference
Stock described below. In all elections for directors, each holder of Western
Resources Preferred Stock or Western Resources Common Stock has the right to
cast as many votes in the aggregate as equals the number of shares held by him
multiplied by the number of directors to be elected; provided, however, that
if the holders of the Western Resources Preferred Stock are entitled to vote
separately as a class for the election of certain directors or the Western
Resources Preferred Stock and the Western Resources Preference Stock are each
entitled to vote separately as a class for the election of certain directors,
the holders of the Common Stock shall be entitled to vote separately as a
class for the remaining directors. The holders of Western Resources Preferred
Stock are entitled to elect a majority of the board of directors if, and so
long as, dividends payable on outstanding Western Resources Preferred Stock
are in default in an amount equal to four or more quarterly dividends, whether
or not consecutive. The holders of Western Resources Preference Stock are
entitled to elect two directors if, and so long as, dividends payable on
outstanding Western Resources Preference Stock are in default in an amount
equal to six or more quarterly dividends, whether or not consecutive. The
holders of the Western Resources Common Stock participate ratably in
liquidation, subject to the payment to the holders of the Western Resources
Preferred Stock and Western Resources Preference Stock of the preferential
amounts to which they are respectively entitled.
 
  Dividends on the Western Resources Common Stock may be declared and paid
only out of surplus or net profits legally available for the payment of
dividends and only when the full dividends on the Western Resources Preferred
Stock and the Western Resources Preference Stock have been paid or declared
and a sum sufficient for the payment thereof shall have been set apart. In
addition, the Western Resources Articles contain further restrictions on the
dividends which may be paid to holders of the Western Resources Common Stock.
In the event the Capitalization Ratio (as defined below) is less than 20%,
dividends (including the proposed payment) on the Western Resources Common
Stock and the Western Resources Preference Stock during the twelve month
period ending with and including the date of the proposed payment of such
dividends may not exceed 50% of the net income available for dividends during
the twelve calendar month period ending with and including the second calendar
month immediately preceding the date of the proposed payment of dividends on
such shares of capital stock. Similarly, if the Capitalization Ratio is 20% or
more, but less than 25%, then the payment of dividends on the Western
Resources Common Stock and the Western Resources Preference Stock (including
the proposed payment) during the twelve month period ending with and including
the date of the proposed payment of such dividends may not exceed 75% of the
net income of Western Resources available for dividends for the twelve
calendar months ending with and including the second calendar month
immediately preceding the date of the proposed payment of dividends on such
shares of capital stock. Except as permitted by the provisions of the Western
Resources Articles summarized in this paragraph, Western Resources may not pay
dividends on the Western Resources Common Stock and the Western Resources
Preference Stock which would reduce the Capitalization Ratio to less than 25%.
"Capitalization Ratio" is defined to mean the ratio of the capital represented
by the Western Resources Common Stock and the Western Resources Preference
Stock, including
 
                                      62
<PAGE>
 
premiums on the capital stock of Western Resources, plus the surplus accounts
of Western Resources, to the total capital of Western Resources, plus the
surplus accounts of Western Resources, at the end of the second calendar month
immediately preceding the date of the proposed payment of dividends, adjusted
to reflect the proposed payment of dividends.
 
WESTERN RESOURCES PREFERRED STOCK
 
  Western Resources is authorized to issue 6,600,000 shares of Western
Resources Preferred Stock, which may be issued from time to time in one or
more series, each such series to have such distinctive designation or title as
may be fixed by the Western Resources board of directors prior to the issuance
of any shares thereof. Each series may differ from each other series already
outstanding as may be declared from time to time by the Western Resources
board of directors in the following respects: (i) the rate of dividend; (ii)
the amount per share, if any, which the Western Resources Preferred Stock
shall be entitled to receive upon redemption, liquidation, distribution or
sale of assets, dissolution or winding up of Western Resources; (iii) terms
and conditions of conversions, if any; and (iv) terms of sinking fund,
redemption or purchase account, if any. As of April 15, 1996, Western
Resources had three series of Par Value Preferred Stock outstanding, the 4
1/2% Series (138,576 shares outstanding), the 4 1/4% Series (60,000 shares
outstanding) and the 5% Series (50,000 shares outstanding), and no shares of
No Par Value Preferred Stock were outstanding.
 
  The Western Resources Preferred Stock has special voting rights which are
triggered when dividends on the stock are in default in an amount equal to
four or more quarterly dividends, whether or not consecutive. If dividends are
not paid for four or more dividend periods on all series of Western Resources
Preferred Stock then outstanding, the holders of the Western Resources
Preferred Stock are entitled to elect the smallest number of directors
necessary to constitute a majority of the full Western Resources board of
directors until such unpaid dividends shall be paid. In addition, Western
Resources may not, without the consent of the holders of at least two-thirds
of the Western Resources Preferred Stock then outstanding, voting as a class,
(i) define or specify preferences, qualifications, limitations or other rights
for authorized but unissued shares of Western Resources Preferred Stock
superior to those of outstanding shares of such stock (except for differences
described in items (i) through (iv) in the previous paragraph) or amend,
alter, change or repeal any of the express terms or provisions of the then
outstanding Western Resources Preferred Stock in a manner substantially
prejudicial to the holders thereof, or (ii) issue or sell any Western
Resources Preferred Stock or any class of stock ranking prior to or on a
parity with the Western Resources Preferred Stock other than in exchange for
or for the purpose of effecting the retirement of not less than a like number
of shares of Western Resources Preferred Stock or shares of stock ranking
prior to or on a parity therewith or securities convertible into not less than
a like number of such shares unless (a) aggregate capital applicable to
Western Resources Common Stock and Western Resources Preference Stock plus
surplus equals the involuntary liquidation preference of all Western Resources
Preferred Stock and any such other stock ranking prior thereto or on a parity
therewith and (b) Western Resources' net earnings (as defined) for a period of
12 consecutive calendar months within the 15 calendar months preceding the
date of issuance, available for the payment of dividends, shall be at least
two times the annual dividend requirements on the Western Resources Preferred
Stock and on any such other stock ranking prior thereto or on a parity
therewith after giving effect to the proposed issuance, and the net earnings
(as defined), for the same period, available for payment of interest shall be
at least one and one-half times the sum of annual interest requirements and
dividend requirements on Western Resources Preferred Stock and such other
stock ranking prior thereto or on a parity therewith after giving effect to
the proposed issuance.
 
  The Western Resources Articles also provide that without the consent of the
holders of at least a majority of the Western Resources Preferred Stock then
outstanding, voting as a class, or if more than one-third shall vote
negatively, Western Resources shall not: (i) merge or consolidate with or into
any other corporation; (ii) sell, lease or exchange all or substantially all
of its property or assets unless the fair value of the net assets of Western
Resources after completion of such transaction shall at least equal the
liquidation value of all outstanding shares of Western Resources Preferred
Stock; or (iii) reacquire or pay any dividends or make any other distribution
upon shares of the Western Resources Preference Stock or the Western Resources
Common Stock or any other class of the stock of Western Resources over which
the Western Resources Preferred Stock
 
                                      63
<PAGE>
 
has preference with respect to the payment of dividends or the distribution of
assets, unless after any such action the sum of (a) the capital of Western
Resources represented by the outstanding Western Resources Preference Stock,
Western Resources Common Stock or other stock over which the Western Resources
Preferred Stock has preference, (b) Western Resources' earned surplus, and (c)
any capital surplus of Western Resources, shall not be less than the sum of
$10,500,000 plus an amount equal to twice the annual dividend requirement on
all outstanding shares of the Western Resources Preferred Stock and on any
such other stock ranking prior thereto or on a parity therewith.
 
  For consideration at Western Resources' 1996 Annual Shareholders Meeting is
a proposal to amend the Western Resources Articles by removing certain voting
rights of the holders of Western Resources Preferred Stock relating to the
issuance of unsecured indebtedness. The Western Resources Articles currently
provide that so long as any shares of Western Resources Preferred Stock are
outstanding, Western Resources shall not, without the consent of the holders
of a majority of the Western Resources Preferred Stock then outstanding,
voting together as a class, or if more than one-third of such shares vote
negatively, issue or assume any unsecured indebtedness (except for refunding
outstanding unsecured securities or redeeming or retiring shares of
outstanding Western Resources Preferred Stock) unless, immediately after such
issuance or assumption, the total principal amount of all outstanding
unsecured indebtedness would not exceed 15% of the total principal amount of
all secured indebtedness, issued or assumed by Western Resources, then to be
outstanding, plus capital and surplus of Western Resources. The proposed
amendment would eliminate such limitation on Western Resources' issuance of
unsecured debt.
 
WESTERN RESOURCES PREFERENCE STOCK
 
   Western Resources is authorized to issue 4,000,000 shares of Western
Resources Preference Stock, which may be issued from time to time in one or
more series, each such series to have such distinctive designation or title as
may be fixed by the board prior to the issuance of any shares thereof. Each
series may differ from each other series already outstanding, as may be
declared from time to time by the Western Resources board of directors, in the
following respects: (i) the rate of dividend; (ii) whether shares of Western
Resources Preference Stock are subject to redemption, and if so, the amount or
amounts per share which the shares of such series would be entitled to receive
in case of redemption, and the terms on which such shares may be redeemed;
(iii) the amounts payable in the case of the liquidation, distribution or sale
of assets, dissolution or winding up of Western Resources; (iv) terms and
conditions of conversion, if any; (v) terms of sinking fund, redemption or
purchase account, if any; and (vi) any designations, preferences and relative
participating, optional or other special rights and qualifications,
limitations or restrictions thereof. As of April 15, 1996, Western Resources
had two series of Western Resources Preference Stock outstanding: the 7.58%
Series, of which 500,000 shares were outstanding; and the 8.50% Series, of
which 1,000,000 shares were outstanding.
 
  The Western Resources Preference Stock has voting rights which are triggered
when dividends on the stock are in default in an amount equal to six or more
quarterly dividends, whether or not consecutive. If dividends are not paid for
six or more dividend periods, the holders of the Western Resources Preference
Stock are entitled to elect two directors to the Western Resources board of
directors until such unpaid dividends shall be paid. In addition, Western
Resources may not, without the consent of the holders of at least two-thirds
of the Western Resources Preference Stock then outstanding, voting as a class,
(i) amend, alter, change or repeal any of the express terms and conditions of
the then outstanding Western Resources Preference Stock in a manner
substantially prejudicial to the holders thereof, or (ii) create any class of
stock ranking prior to the Western Resources Preference Stock as to dividends
or upon liquidation, or securities convertible into shares ranking prior to
the Western Resources Preferred Stock in such respects; provided, no such
consent shall be required with respect to the taking of any such action
relating to the Western Resources Preferred Stock.

                      DESCRIPTION OF KCPL'S CAPITAL STOCK
 
THE SHARES
 
  The KCPL Charter provides that KCPL has authority to issue 150,000,000
Shares. According to the UtiliCorp/KCPL Joint Proxy/Prospectus, as of April 3,
1996, there were 61,902,083 Shares issued and outstanding.
 
  Holders of Shares are entitled to one vote per Share held, with the right of
cumulative voting in the election of directors. Holders of Shares are entitled
to receive dividends from funds legally available therefor, when and as
declared by the KCPL board of directors, and are entitled upon liquidation to
receive pro rata the net assets of KCPL after satisfaction in full of the
prior rights of creditors of KCPL and holders of the Cumulative Preferred
Stock, Cumulative No Par Preferred Stock and the KCPL Preference Stock (as
defined below).
 
  UMB Bank, N.A., is the Transfer Agent and Registrar for the Shares.
 
CUMULATIVE PREFERRED STOCK AND CUMULATIVE NO PAR PREFERRED STOCK
 
  The KCPL Charter authorizes the issuance of 409,157 shares of Cumulative
Preferred Stock, par value $100 per share and 1,572,000 shares of Cumulative
No Par Preferred Stock, without par value (the Cumulative Preferred Stock and
the Cumulative No Par Preferred Stock are referred to collectively as the
"KCPL Preferred Stock"). On December 31, 1995, KCPL had 404,357 shares of
Cumulative Preferred Stock outstanding and 500,000 shares of Cumulative No Par
Preferred Stock outstanding. The KCPL Preferred Stock may be issued from time
to time in one or more series and the KCPL board of directors is authorized to
determine or alter the powers, preferences and rights, and the qualifications,
limitations or restrictions to be granted or imposed upon the KCPL Preferred
Stock. Thus, the KCPL board of directors is authorized to designate and fix
with respect to each series of KCPL Preferred Stock the specific designation
of such series, the dividend rate, the terms of redemption, the terms and
amount of any sinking fund and conversion rights, all without further action
by the holders of the Shares.
 
  The holders of each series of KCPL Preferred Stock are entitled to receive
dividends from funds legally available therefor when, as and if declared by
the KCPL board of directors and are entitled upon liquidation to receive an
amount per share equal to that which such holders would have been entitled to
receive had shares held by them been redeemed. The shares of KCPL Preferred
Stock now outstanding have preference over the Shares with respect to the
payment of dividends and distribution of assets in the event of the
liquidation, winding up or dissolution of Western Resources.
 
  Generally, the holders of each series of KCPL Preferred Stock have no voting
rights. However, the holders of KCPL Preferred Stock are entitled to vote as a
single class for the approval of a merger or consolidation, except that no
consent of the holder of KCPL Preferred Stock is required with respect to any
merger or consolidation approved by the Commission under the 1935 Act, unless
such stock is to be redeemed prior to the effective time of the merger or
consolidation. Furthermore, if the equivalent of four quarterly dividends
payable on a series of KCPL Preferred Stock are in default, the holders of
KCPL Preferred Stock, voting as a single class, may elect the smallest number
of Directors necessary to constitute a majority of the full KCPL board of
directors.
 
PREFERENCE STOCK
 
  The KCPL Charter provides that KCPL has the authority to issue 11,000,000
shares of preference stock with no par value (the "KCPL Preference Stock"). On
December 31, 1995, no shares of Preference Stock were outstanding. The KCPL
Preference Stock may be issued from time to time in one or more series with
such rights, preferences and limitations as are specified by the KCPL board of
directors. The KCPL board of directors is authorized to establish, designate
and fix, with respect to each series of KCPL preference shares, the
designation of such series, the dividend rate, right of redemption and the
price, sinking fund provisions and voting rights, all without further action
by the holders of the Shares.

                    COMPARISON OF THE RIGHTS OF HOLDERS OF
                   SHARES AND WESTERN RESOURCES COMMON STOCK
 
  As a consequence of the Merger, shareholders of KCPL, a Missouri
corporation, will become shareholders of Western Resources, a Kansas
corporation. The rights of KCPL shareholders are currently governed by
Missouri law (including the MGBCL), the KCPL Charter and the KCPL Bylaws. Upon
consummation of the Merger, the rights of KCPL shareholders will be governed
by Kansas law (including the Kansas General Corporation Code (the "KGCC")),
the Western Resources Articles and the Western Resources Bylaws. The following
is a summary of certain similarities and material differences between the
rights of holders of KCPL Common Stock and the rights of holders of Western
Resources Common Stock.
 
  The following summary does not purport to be a complete statement of the
rights of KCPL shareholders under Missouri law, the KCPL Charter and the KCPL
Bylaws as compared with the rights of Western Resources shareholders under
Kansas law, the Western Resources Articles and the Western Resources Bylaws,
or a complete description of the specific provisions referred to herein. The
summary is qualified in its entirety by reference to the governing corporate
instruments, including the aforementioned instruments of KCPL and Western
Resources.
 
  Special Meetings of Shareholders. Section 351.225.3 of the MGBCL permits the
board of directors or such other person or persons as may be authorized in the
articles of incorporation or bylaws to call a special meeting of shareholders.
The KCPL Bylaws provide that a special meeting of shareholders may be called
only by the Chairman of the KCPL board of directors, by the President, or at
the written request of a majority of the KCPL board of directors.
 
  Section 17-6501(e) of the KGCC provides that special meetings of
shareholders may be called by the board of directors or by such person or
persons as may be authorized by the articles of incorporation or bylaws. The
Western Resources Bylaws provide that a special meeting of shareholders may be
called by the Western Resources Board, the Chairman or the President.
 
  Number of Directors. Section 351.315.1 of the MGBCL provides that a
corporation shall have three or more directors, except that a corporation may
have one or two directors if stated in the articles of incorporation. The KCPL
Bylaws fix the number of directors to be elected at the annual meeting of
shareholders at nine (9). The number of directors may be increased at a
special meeting called for such purpose by a majority of the shareholders
present and entitled to vote at such meeting.
 
  Section 17-6301(b) of the KGCC provides that the board of directors of a
corporation shall consist of one or more members. The number of directors
shall be fixed by, or in the manner provided in, the bylaws, unless the
articles of incorporation establish the number of directors, in which case a
change in the number of directors shall be made only by amendment of the
articles of incorporation. Directors need not be shareholders unless so
required by the articles of incorporation or the bylaws. The articles of
incorporation or bylaws may prescribe other qualifications for directors. The
Western Resources Articles provides that the number of directors shall not be
less than seven nor more than fifteen, the precise number to be set by the
Western Resources board of directors, provided that unless approved by a
majority of shareholders entitled to vote, the number of directors shall not
be reduced if such reduction will shorten the term of an existing director.
 
  Advance Notice of Shareholder Nominations of Directors.  Under the KCPL
Bylaws, nominations of persons for election to the KCPL board of directors may
be made at a meeting of shareholders by any shareholder who is a shareholder
of record on both the date notice of the meeting is given and on the record
date for the meeting, provided that the Secretary of KCPL receives proper
written notice of such nomination not less than sixty days nor more than
ninety days prior to the meeting. If less than seventy days notice or prior
public disclosure of the date of the meeting is given or made by KCPL to
shareholders, the notice of nomination must be received not later than the
close of business on the tenth day following the day on which such notice of
the date of the meeting was mailed or public disclosure was made, whichever
occurs first.
 
                                      66
<PAGE>
 
  The Western Resources Articles provide a similar advance notice provision.
Nominations of persons for election to the Western Resources board of
directors may be made at a meeting of shareholders by any shareholder,
provided that the Secretary of Western Resources receives written notice not
less than thirty-five days nor more than fifty days prior to the meeting. In
the event that less than forty-five days notice or prior public disclosure of
the date of the meeting is given or made by Western Resources to shareholders,
the notice of nomination must be received not later than the close of business
on the tenth day following the day on which such notice of the date of the
meeting was mailed or public disclosure was made. For notice by the
shareholder to be timely, it must be received in any event not later than the
close of business on the seventh day preceding the day on which the meeting is
to be held. Such notice shall contain (i) the names of the nominees and all
other information required to be disclosed in a proxy statement, (ii) the name
and address of the shareholder making the nomination, (iii) a representation
that the shareholder is a holder of record of the stock entitled to vote at
the meeting on the date of the notice and intends to appear in person or by
proxy at the meeting to nominate the person specified in the notice and (iv) a
description of all arrangements or understandings between the shareholder and
each nominee and any other person on whose behalf such nominations are being
made.
 
  Shareholder Proposal Procedures. Pursuant to the KCPL Bylaws, business is
properly brought before an annual meeting if any shareholder of KCPL who is a
shareholder of record on both the date notice of the meeting is given and on
the record date for the meeting provides the Secretary of KCPL with proper
written notice not less than sixty days nor more than ninety days prior to the
meeting. If less than seventy days notice or prior public disclosure of the
date of the meeting is given or made by KCPL to shareholders, the notice must
be received not later than the close of business on the tenth day following
the day on which such notice of the date of the meeting was mailed or public
disclosure was made, whichever occurs first.
 
  The Western Resources Articles permit any shareholder who is a holder of
record at the time of giving the required notice and who is entitled to vote
at the shareholders meeting, to bring business before such shareholders
meeting. Required notice must be received by the Secretary of Western
Resources not less than thirty-five days nor more than fifty days prior to the
meeting. In the event that less than forty-five days notice or prior public
disclosure of the date of the meeting is given or made by Western Resources to
shareholders, the notice must be received not later than the close of business
on the tenth day following the day on which such notice of the date of the
meeting was mailed or public disclosure was made. For notice by the
shareholder to be timely, it must be received in any event not later than the
close of business on the seventh day preceding the day on which the meeting is
to be held. The notice shall contain (i) a brief description of the business
desired to be brought forth and the reasons for considering the business, (ii)
the name and address of the shareholder as they appear on the books of Western
Resources, (iii) a representation that such shareholder is a holder of record
of the stock entitled to vote at the meeting on the date of the notice and
intends to appear in person or by proxy to present the business specified in
the notice and (iv) disclosure of any material interest of the shareholder in
such proposal.
 
  Classification of Board of Directors. Section 351.315.1 of the MGBCL
provides that any Missouri corporation may elect its directors for one or more
years, not to exceed three years, the time of service and mode of
classification to be provided for by the articles of incorporation or the
bylaws of the corporation, provided, that there shall be an annual election
for such number of directors as may be found upon dividing the entire number
of directors by the number of years composing a term. The KCPL board of
directors is not classified and the KCPL Bylaws provide that each director
will be elected annually to a one-year term.
 
  Section 17-6301(d) of the KGCC provides that the directors of any
corporation may be divided into one, two or three classes by the articles of
incorporation or by the corporation's initial bylaws, or by bylaws adopted by
a vote of the shareholders; the term of office of those of the first class to
expire at the annual meeting next ensuing; of the second class one year
thereafter; of the third class two years thereafter; and at each annual
election held after such classification and election, directors shall be
chosen for a full term, as the case may be, to succeed those whose terms
expire. The Western Resources Bylaws provide for three classes of directors as
nearly equal as possible with no class containing fewer than two directors and
with each holding office for a term of three years.
 
 
                                      67
<PAGE>
 
  Cumulative Voting. Both the MGBCL and the KGCC allow, but do not require,
cumulative voting for the election of directors. Under the KCPL Bylaws, KCPL
shareholders have cumulative voting rights for the election of directors.
Accordingly, each holder of shares eligible to vote for the election of
directors may cast a number of votes in the aggregate equal to the number of
shares held by that holder multiplied by the number of directors to be
elected, and such votes may be cast for one candidate or distributed among two
or more candidates at the shareholder's discretion. The Western Resources
Bylaws also provide for cumulative voting of all shares entitled to vote for
the election of directors.
 
  Removal of Directors: Filling Vacancies on the Board of Directors. The KCPL
Bylaws are silent on the issue of removal of directors. The MGBCL provides,
however, that one or more directors may be removed at a duly called special
meeting, with or without cause, by a vote of the holders of a majority of the
shares then entitled to vote at an election of directors. Under the MGBCL, in
the case of a corporation having cumulative voting for the election of
directors, such as KCPL, if less than the entire board is to be removed, no
director may be removed if the votes cast against such removal would be
sufficient to elect the director by cumulative voting at a duly convened
meeting to elect directors. Additionally, a majority of the entire KCPL board
of directors may remove a director if, at the time of removal, such director
fails to meet the qualifications for election stated in the KCPL Charter or
Bylaws or if he is in breach of any agreement between such director and KCPL
relating to his services to such corporation as a director or employee. Prior
notice of such proposed removal must be given to all directors.
 
  The KCPL Bylaws provide that vacancies on the KCPL board of directors may be
filled by a majority of the remaining directors, though less than a quorum,
until the successor or successors are elected at a meeting of the
shareholders.
 
  The KGCC provides that any director or the entire board of directors may be
removed, with or without cause, by the holders of a majority of shares then
entitled to vote at an election of directors, except that in the case of a
corporation having a classified board of directors, such as Western Resources,
shareholders may remove a director only for cause, unless the articles of
incorporation otherwise provide. Under the Western Resources Bylaws, no
director may be removed except for cause. Pursuant to the KGCC, in the case of
a corporation with cumulative voting, if less than the entire board is to be
removed, no director may be removed without cause if the votes cast against
such director's removal would be sufficient to elect such director if then
cumulatively voted at an election of the entire board of directors or, in the
case of a corporation having classes of directors, such as Western Resources,
at an election of the class of directors of which such director is a part.
 
  Pursuant to the Western Resources Bylaws, vacancies in the Western Resources
board of directors, caused by death, resignation or otherwise, may be filled
at any meeting of the Western Resources board of directors and such
replacement directors shall serve until the next annual meeting of
shareholders and until their successors are elected and qualified.
 
  Shareholder Action by Written Consent. Under both Section 351.273 of the
MGBCL and Section 17-6518 of the KGCC (except as otherwise provided in the
articles of incorporation of a Kansas corporation), any action which may be
taken by shareholders at any annual or special meeting may be taken without a
meeting by written consent, provided that such consent is unanimous.
 
  Preemptive Rights. No shareholder of KCPL or Western Resources has
preemptive rights with regard to shares of common or preferred stock.
 
  Amendment of KCPL Charter and Western Resources Articles. The KCPL Charter
may be amended in accordance with Missouri law. Section 351.090 of the MGBCL
provides that the board of directors may adopt a resolution setting forth the
proposed amendment and directing that it be submitted to a vote at a meeting
of shareholders, which may be either an annual or a special meeting, except
that the proposed amendment need not be adopted by the board of directors and
may be directly submitted to any annual or special meeting of
 
                                      68
<PAGE>
 
shareholders. Missouri law further provides that written notice setting forth
the proposed amendment or a summary of the changes to be effected shall be
given to each shareholder of record entitled to vote within the time and in
the manner for the giving of notice of meetings of shareholders. If the
meeting is an annual meeting, the proposed amendment or summary shall be
included in the notice of the annual meeting. At the meeting a vote of the
shareholders entitled to vote shall be taken on the proposed amendment. The
proposed amendment shall be adopted upon receiving the affirmative vote of a
majority of the outstanding shares entitled to vote, unless any class of
shares is entitled to vote as a class, in which event the proposed amendment
shall be adopted upon receiving the affirmative vote of a majority of the
outstanding shares of each class of shares entitled to vote as a class and of
the total shares entitled to vote.
 
  The Western Resources Articles provide that until and unless a specific
provision for amending the Western Resources Articles is specially adopted,
Western Resources reserves the right, except as otherwise provided, to amend,
alter, change, or repeal any provision contained in the Western Resources
Articles in the manner now or hereafter prescribed by the applicable
provisions of the laws of the State of Kansas for amending the articles of
incorporation of a Kansas corporation, and all rights conferred upon
shareholders are granted subject to such reservation.
 
  The KGCC provides that in connection with every amendment authorized by
Section 17-6602 of KGCC, the board of directors shall adopt a resolution
setting forth the amendment proposed, declaring its advisability, and either
calling a special meeting of the shareholders entitled to vote for the
consideration of such amendment or directing that the amendment proposed be
considered at the next annual meeting of the shareholders. Kansas law further
provides that written notice shall be given to each shareholder entitled to
vote at the meeting within the time and in the manner for the giving of notice
of meetings of shareholders. The notice shall set forth such amendment in full
or a brief summary of the changes to be effected. If a majority of the
outstanding stock entitled to vote and a majority of the outstanding stock of
each class entitled to vote thereon as a class have been voted in favor of the
amendment, a certificate setting forth the amendment and certifying that such
amendment has been duly adopted shall be executed, acknowledged, filed and
recorded.
 
  Amendment of Bylaws. The KCPL board of directors may make, alter, amend or
repeal the KCPL Bylaws by a majority vote of the whole KCPL board of directors
at any regular or special meeting of the KCPL board of directors provided
notice thereof has been given in the notice of such special meeting. The
shareholders may also amend the KCPL Bylaws at any shareholder meeting at
which a quorum is present by a majority vote of the shareholders present and
entitled to vote.
 
  The Western Resources board of directors may make and from time to time
alter, amend or repeal any Western Resources Bylaw, subject to the power of
the shareholders to amend, alter or repeal such Western Resources Bylaws. The
provisions of the Western Resources Bylaws regarding the classification of the
Western Resources board of directors, the filling of vacancies by directors
and the removal of directors may not be amended without the affirmative vote
of at least 80% of the outstanding shares of Western Resources entitled to
vote.
 
  Business Combinations. Article XII of the KCPL Charter provides that an
affirmative vote of at least 80% of the outstanding shares of KCPL Common
Stock entitled to vote shall be required for the approval or authorization of
any Business Combination with an Interested Shareholder; provided that such
80% voting requirement shall not be applicable if: (a) the Business
Combination shall have been approved by a majority of the Continuing
Directors; or (b) the cash or the Fair Market Value of the property,
securities or other consideration to be received in such Business Combination
is not less than the highest per share price paid by or on behalf of the
Interested Shareholder for any Shares during the five year period preceding
the commencement of such Business Combination. For purposes of the foregoing
provisions, an "Interested Shareholder" is defined as (i) any individual,
corporation, partnership or other person or entity, which together with its
"Affiliates" or "Associates" as such terms are defined in Rule 12b-2 under the
Exchange Act beneficially owns, as such term is defined in Rule 13d-3 under
the Exchange Act, in the aggregate 5% or more of the outstanding Common Stock
and (ii) any Affiliate or Associate of such Interested Shareholder;
"Continuing Directors" is defined as any director who is unaffiliated with the
Interested Shareholder and was a director prior to the Interested Shareholder
 
                                      69
<PAGE>
 
becoming an Interested Shareholder, and any successor of a Continuing Director
if unaffiliated with the Interested Shareholder and recommended to succeed the
Continuing Director by a majority of Continuing Directors; "Substantial Part"
means 10% or more of the Fair Market Value of KCPL's total assets as reflected
in the most recent balance sheet; and "Fair Market Value" is defined as (i) in
the case of stock, the highest closing sale price during the 30 day period
immediately prior to the date in question of a share of such stock on the
NYSE; and (ii) in the case of property other than cash, or stock, the Fair
Market Value of such property on the date in question as determined by a
majority of the Continuing Directors.
 
  Business Combinations requiring such a vote include: (i) any merger or
consolidation of KCPL or any of its subsidiaries with any Interested
Shareholders; (ii) any sale, lease, exchange, transfer or other disposition of
any Substantial Part of the assets of KCPL or a subsidiary to an Interested
Shareholder; (iii) the issuance of any securities of KCPL to an Interested
Shareholder other than an issuance on a pro rata basis to all holders of
shares pursuant to a stock split or dividend; (iv) any recapitalization or
reclassification that would increase the proportionate voting power of an
Interested Shareholder; (v) any liquidation, spinoff, split-up or other
dissolution of KCPL proposed on behalf of an Interested Shareholder; or (vi)
any agreement, contract, arrangement or understanding providing for any of the
above transactions.
 
  Article XII of the KCPL Charter may not be amended or repealed except by the
affirmative vote of at least 80% of the outstanding shares of KCPL Common
Stock entitled to vote.
 
  Article XVII of the Western Resources Articles provides that an affirmative
vote of at least 80% of the voting stock of Western Resources and the
affirmative vote of at least a majority of the voting stock held by
shareholders other than an Interested Shareholder shall be required for the
approval or authorization of any Business Combination with an Interested
Shareholder; provided that such 80% voting requirement not be applicable if:
(a) the Business Combination shall have been approved by a majority of the
Continuing Directors; or (b) the cash or the Fair Market Value (as determined
by a majority of the Continuing Directors) of the property, securities or
other consideration to be received in such Business Combination is not less
than the highest per share price paid on behalf of the Interested Shareholder
for any shares of the Western Resources stock.
 
  "Business Combinations" requiring such a vote include: (i) any merger or
consolidation of Western Resources or any of its subsidiaries with any
Interested Shareholder; (ii) any sale, lease, exchange, transfer or other
disposition of any Substantial Part of the assets of Western Resources or a
subsidiary to an Interested Shareholder; (iii) the issuance of any securities
of Western Resources or a subsidiary to an Interested Shareholder other than
an issuance on a pro rata basis to all holders of shares pursuant to a stock
split or dividend; (iv) any recapitalization or reclassification that would
increase the proportionate voting power of an Interested Shareholder; (v) any
liquidation or dissolution of Western Resources proposed on behalf of an
Interested Shareholder; or (vi) any agreement, contract, arrangement or
understanding providing for any of the above transactions. "Fair Market Value"
is defined as (i) in the case of stock, the highest closing sale price during
the 30 day period immediately prior to the date in question of a share of such
stock on the NYSE or such other exchange or quotation system; and (ii) in the
case of property other than cash, or stock, the Fair Market Value of such
property on the date in question as determined by a majority of the Continuing
Directors.
 
  The affirmative vote of 80% of the voting stock of Western Resources and the
affirmative vote of a majority of the voting stock, other than the stock held
by an Interested Shareholder, shall be required to amend, repeal or adopt any
provision inconsistent with Article XVII of the Western Resources Articles.
 
VOTING RIGHTS IN CONNECTION WITH MERGERS AND CONSOLIDATIONS
 
  Generally. A plan of merger or consolidation must be approved by the KCPL
board of directors, submitted to the shareholders of KCPL for approval at a
shareholder meeting, and must obtain the approval of the holders of at least
two-thirds of the outstanding shares entitled to vote at such meeting (MGBCL
Sections 351.410, 415, 420, 425, 458).
 
                                      70
<PAGE>
 
  Preferred Shares. The KCPL Charter provides that the approval of a merger or
consolidation shall require the vote of a majority of the outstanding shares
of KCPL Preferred Stock (as defined herein), voting as a single class, except
that such vote is not required (i) with respect to any merger or consolidation
ordered, approved or permitted by the Commission under the 1935 Act or (ii) if
provision for redemption of the KCPL Preferred Stock is made prior to the
effective time of the merger or consolidation.
 
  Section 351.093 of the MGBCL provides that the holders of the outstanding
shares of a class of stock shall be entitled to vote as a class upon a
proposed amendment, even if that stock confers no or limited voting rights
under the corporate charter, if such amendment would impair the relative
rights or preferences of that stock. The MGBCL does not specify whether a
class of stock would be entitled to vote on a merger whose effect would be the
same as an amendment to the articles of incorporation, but the possibility of
such an interpretation should be considered.
 
  Section 17-6701 of the KGCC provides that an agreement of merger or
consolidation shall be approved by resolution adopted by the board of
directors of the corporation and approved by a majority of the outstanding
stock entitled to vote thereon, subject to certain exceptions.
 
  The Western Resources Articles provide that so long as Western Resources
Preferred Stock (as defined herein) is outstanding, Western Resources may not
merge or consolidate with any other corporation without (i) the consent of the
holders of at least a majority of the shares of Western Resources Preferred
Stock then outstanding voting separately as a class and (ii) if more than one-
third of such holders of the Western Resources Preferred Stock shall vote
negatively, the vote of the percentage or number of shares of any and all
classes required by the law or the Western Resources Articles; provided,
however, that no consent of the Western Resources Preferred Stock shall be
required, except as otherwise required by law, with respect to (i) any merger
approved by the Commission under the 1935 Act or (ii) if provision for
redemption of the Western Resources Preferred Stock is made prior to the
effective time of the Merger or Consolidation.
 
  Dissenters' Rights. Pursuant to Section 351.455 of the MGBCL, if a
shareholder of a corporation which is a party to a merger files with the
corporation a written objection to such merger before the meeting at which the
merger is submitted to a shareholder vote, does not vote in favor of the
merger and, within twenty days after the merger is consummated (or, pursuant
to Section 351.447, within twenty days after being notified of a short-form
merger), makes written demand for the payment of the fair value of his shares
(determined as of the day prior to the date on which the vote approving the
merger was taken), the new or surviving corporation must pay such fair value.
Any shareholder who fails to make such a demand within twenty days after the
merger is conclusively presumed to have consented thereto and is bound by the
terms thereof.
 
  Section 17-6712 of the KGCC provides that a shareholder has the right to
dissent from and receive payment of the value of such shares in the event of
the consummation of a plan of merger or consolidation in which the shareholder
has a right to vote or which is a short-form merger. The KGCC further
provides, however, that unless otherwise provided in the articles of
incorporation of the Kansas corporation, this section does not apply to the
holders of any class or series which, on the record date, were either
registered on a national securities exchange or were held of record by at
least 2,000 shareholders.
 
  Missouri Control Share Acquisition Statute. Section 351.407 of the MGBCL
(the "Missouri Control Share Acquisition Statute"), a copy of which is
attached hereto as Schedule C and is incorporated by reference herein, may
have the effect of eliminating all voting rights attached to Shares acquired
by Western Resources in the Offer.
 
  In summary terms, a "control share acquisition" is the direct or indirect
acquisition (other than acquisitions permitted by the Missouri Control Share
Acquisition Statute as discussed below) by any person of ownership of, or the
power to direct the exercise of voting power with respect to, issued and
outstanding shares of a Missouri "issuing public corporation" that, except for
the Missouri Control Share Acquisition Statute, would have voting power with
respect to shares of such corporation that, when added to all other shares of
such corporation owned
 
                                      71
<PAGE>
 
by such person or in respect to which such person may exercise or direct the
exercise of voting power, would entitle such person, immediately after
acquisition of such shares, to exercise or direct the exercise of the voting
power of such corporation in the election of directors within any of the
following ranges of voting power: (i) one-fifth or more but less than one-
third of all voting power; (ii) one-third or more but less than a majority of
all voting power; or (iii) a majority or more of all voting power.
 
  This provision applies to issuing public corporations which are corporations
with 100 or more shareholders, a principal place of business, principal office
or substantial assets in Missouri and either more than 10% of their
shareholders resident in Missouri, at least 10% of their shares owned by
Missouri residents or at least 10,000 shareholders resident in Missouri. KCPL
meets these tests and is thus an issuing public corporation in Missouri.
 
  Pursuant to the Missouri Control Share Acquisition Statute, shares acquired
in a control share acquisition have no voting rights unless voting rights are
granted by resolution of the shareholders of such corporation. For such a
resolution to be adopted, it must be approved by the affirmative vote of: (i)
a majority of all outstanding shares entitled to vote at a special meeting of
shareholders voting by class if required by the terms of such shares; and (ii)
a majority of all outstanding shares entitled to vote at such meeting voting
by class if required by the terms of such shares, excluding all interested
shares. "Interested shares" means the shares of such corporation in respect of
which any of the following persons may exercise or direct the exercise of the
voting power of the corporation in the election of directors: (a) an acquiring
person or member of a group with respect to a control share acquisition; (b)
any officer of such corporation elected or appointed by the directors of such
corporation or (c) any employee of such corporation who is also a director of
such corporation.
 
  Any person who proposes to make or has made a control share acquisition may
at the person's election deliver an acquiring person statement to such
corporation at the corporation's principal office. The acquiring person
statement must set forth, among other things, certain information regarding
the acquiring person, its holdings of shares of such corporation and details
of such person's control share acquisition or proposed control share
acquisition. If the acquiring person so requests at the time of delivery of a
control share acquisition statement and gives an undertaking to pay the
corporation's expenses of a special meeting, the directors of the corporation
shall within ten days thereafter call a special meeting of shareholders of
such corporation for the purpose of considering the voting rights to be
accorded the shares acquired or to be acquired in the control share
acquisition. Unless the acquiring person agrees to a later date, such a
special meeting shall be held within fifty days after receipt by the
corporation of such request.
 
  Under the Missouri Control Share Acquisition Statute, several acquisitions
of shares are deemed not to constitute control share acquisitions, including
among others, acquisitions of shares (i) pursuant to a will or other
testamentary disposition, or by gift where such gift is made in good faith and
not for the purpose of circumventing the Missouri Control Share Acquisition
Statute, (ii) pursuant to a public offering, a private placement, or any other
issuance of shares by such corporation, (iii) by, on behalf of, or pursuant to
any benefit or other compensation plan or arrangement of such corporation,
(iv) pursuant to the conversion of debt securities into shares of such
corporation under the terms of such debt securities, (v) pursuant to a binding
contract, other than any contract created by, pursuant to, or in connection
with a tender offer, whereby the holders of shares representing at least two-
thirds of the voting power of such corporation, such holders acting
simultaneously, agreed to sell such shares to any person, (vi) pursuant to a
merger or consolidation effected in compliance with Sections 351.410 to
351.458 of the MGBCL if such corporation is a party to the agreement of merger
or consolidation, (vii) pursuant to a binding contract with any person which,
at any time within one year prior to the acquisition in question, owned shares
representing more than fifty percent of the voting power of such corporation
and (viii) by or from any person whose shares have been previously accorded
voting rights pursuant to the Missouri Control Share Acquisition Statute;
provided, such acquisition entitles the person making the acquisition to
exercise or direct the exercise of voting power of such corporation in the
election of directors within a range of the voting power not in excess of the
range of voting power associated with the shares to which voting rights have
been previously accorded.

  In addition, a corporation may exempt itself from application of the
Missouri Control Share Acquisition Statute by inserting a provision in its
articles of incorporation or bylaws expressly electing not to be covered by
the statute. The KCPL Charter and the KCPL Bylaws do not "opt out" of the
Missouri Control Share Acquisition Statute.
 
  The foregoing does not purport to be a complete description of the Missouri
Control Share Acquisition Statute. HOLDERS OF SHARES ARE URGED TO, AND SHOULD,
READ SECTION 351.407 OF THE MGBCL (AND THE RELATED DEFINITIONS INCLUDED
THEREIN), A COPY OF WHICH IS ATTACHED HERETO IN ITS ENTIRETY AS SCHEDULE C.
 
  Kansas Control Share Transaction Provision. Pursuant to Section 17-1286 of
the Kansas Statutes Annotated (the "Kansas Control Share Acquisition
Provision"), control shares are shares of an issuing public corporation that
would, except for application of the statute, entitle their holder to exercise
or direct the exercise of voting power in the election of directors within
certain specified ranges (one-fifth or more but less than one-third, one-third
or more but less than a majority, a majority or more). A control share
acquisition is an acquisition, directly or indirectly, by any person of
ownership of, or power to direct the voting of control shares, either pursuant
to a single transaction or various transactions within a 120 day period, or
pursuant to a plan to make a control share acquisition.
 
  This provision applies to shares of an issuing public corporation which has
100 or more shareholders, a principal place of business, principal office or
substantial assets in Kansas and either more than 10% of its shareholders
resident in Kansas or at least 10% of its shares owned by Kansas residents or
at least 2,500 shareholders resident in Kansas. Western Resources meets these
tests and is thus an issuing public corporation in Kansas.
 
  Control shares acquired in a control share acquisition shall have the same
voting rights as before the acquisition only to the extent approved by a
majority of all shares entitled to vote in the election of directors and a
majority of all shares entitled to vote in the election of directors,
excluding all interested shares. An acquiring person can request a special
meeting of shareholders to consider the voting rights that will attach to his
or her control shares.
 
  Interested shares are those over which (i) a person or group that makes or
proposes to make a control share acquisition, (ii) an officer of the issuing
public corporation, or (iii) an employee of the issuing public corporation who
is also a director, exercises voting power.
 
  An issuing public corporation can opt out of the Kansas Control Share
Acquisition Provision with a provision in either its articles of incorporation
or its by-laws stating that it does not apply. The opt-out is effective only
with regard to control share acquisitions which occur after the opt-out has
been adopted by the by-laws or articles of incorporation. The Western
Resources Articles and the Western Resources Bylaws do not contain an opt-out
at this time.
 
  Unless otherwise provided in the corporation's by-laws or articles of
incorporation, control shares may be redeemed if an acquiring person statement
has not been delivered to the corporation by the tenth day after the control
share acquisition, or if a statement has been filed but the shareholders have
voted not to accord voting rights to the control shares. A call for redemption
must occur within 30 days after the event that gives the corporation the
option to redeem the shares and the shares must be redeemed within 60 days of
such call.
 
  The definition of "control share acquisition" sets forth certain exceptions,
including, without limitation, the acquisition of shares in certain statutory
mergers or consolidations to which the issuing public corporation is a party.
 
  Missouri Business Combination Statute. Section 351.459 of the MGBCL (the
"Missouri Business Combination Statute"), a copy of which is attached hereto
as Schedule D and is incorporated by reference herein, protects Missouri
corporations from certain transactions.
 
 
                                      73
<PAGE>
 
  The Missouri Business Combination Statute prevents a Missouri corporation
from engaging in any "business combination" with any "interested shareholder"
of such corporation for a period of five years following such interested
shareholder's stock acquisition date unless such business combination or the
purchase of stock made by such interested shareholder on such interested
shareholder's stock acquisition date is approved by the board of directors of
such corporation on or prior to such stock acquisition date. A "business
combination" includes, among other things, a merger or consolidation, certain
sales, leases, exchanges, mortgages, transfers, pledges and similar
dispositions of corporate assets or stock and any reclassifications,
recapitalizations and reorganizations that increase the proportionate voting
power of the interested shareholder. An "interested shareholder" is defined
generally as the "beneficial owner" (as such term is defined in the Missouri
Business Combination Statute) of twenty percent (20%) or more of the
outstanding voting stock of such corporation or an "affiliate" or "associate"
(as such terms are defined in the Missouri Business Combination Statute) and
at any time within the preceding five years was the beneficial owner of twenty
percent (20%) or more of the outstanding voting stock of such corporation. The
"stock acquisition date", with respect to any person and any Missouri
corporation, means the date that such person first becomes an interested
shareholder of such corporation.
 
  In addition, the Missouri Business Combination Statute provides that a
Missouri corporation may not engage at any time in a business combination with
an interested shareholder other than any of the following business
combinations: (i) a business combination approved by the board of directors of
such corporation prior to such interested shareholder's stock acquisition
date, or where the purchase of stock made by such interested shareholder on
such interested shareholder's stock acquisition date had been approved by the
board of directors of such corporation prior to such interested shareholder's
stock acquisition date; (ii) a business combination approved by the
affirmative vote of the holders of a majority of the outstanding voting stock
not beneficially owned by such interested shareholder or any affiliate or
associate of such interested shareholder at a meeting called for such purpose
no earlier than five years after such interested shareholder's stock
acquisition date; (iii) a business combination that meets certain detailed
fairness and procedural requirements. Notwithstanding the foregoing, unless
the board of directors of the corporation approved such business combination
prior to the date on which the interested shareholder acquired such status, no
such business combination may be engaged in for a period of five years after
such date.
 
  Thus, the Missouri Business Combination Condition may be satisfied by the
approval of the Offer or the Merger by the KCPL board of directors prior to
the consummation of the Offer.
 
  The Missouri Business Combination Statute does not apply to: (i)
corporations that do not have a class of voting stock registered under Section
12 of the Exchange Act, unless the certificate of incorporation provides
otherwise; (ii) any business combination of a Missouri corporation whose
certificate of incorporation has been amended to provide that such corporation
shall be subject to the provisions of such statute, which did not have a class
of voting stock registered with the Commission pursuant to Section 12 of the
Exchange Act on the effective date of such amendment, and which is a business
combination with an interested shareholder whose stock acquisition date is
prior to the effective date of such amendment; (iii) any business combination
of a Missouri corporation the original certificate of incorporation of which
contains a provision expressly electing not to be governed by this section, or
which adopts an amendment to such corporation's bylaws prior to August 1,
1986, expressly electing not to be governed by such statute, or which adopts
an amendment to such corporation's bylaws, approved by the affirmative vote of
the holders, other than interested shareholders and their affiliates and
associates, expressly electing not to be governed by such statute, provided
that such amendment to the bylaws shall not be effective until eighteen months
after such vote of such corporation's shareholders and shall not apply to any
business combination of such corporation with an interested shareholder whose
stock acquisition date is on or prior to the effective date of such amendment;
(iv) any business combination of a Missouri corporation with an interested
shareholder of a domestic corporation which became an interested shareholder
inadvertently, if such interested shareholder, as soon as practicable, divests
itself of a sufficient amount of the voting stock of such corporation so that
it no longer is the beneficial owner, directly or indirectly, of twenty
percent or more of the outstanding voting stock of such corporation, and would
not at any time within the five-year period preceding the announcement date
with respect to such business combination have been an interested
 
                                      74
<PAGE>
 
shareholder but for such inadvertent acquisition; or (v) any business
combination with an interested shareholder who was the beneficial owner,
directly or indirectly, of five percent or more of the outstanding voting
stock of such corporation on December 1, 1985, and remained so to such
interested shareholder's stock acquisition date.
 
  The foregoing does not purport to be a complete description of the Missouri
Business Combination Statute. HOLDERS OF SHARES ARE URGED TO, AND SHOULD, READ
SECTION 351.459 OF THE MGBCL, A COPY OF WHICH IS ATTACHED HERETO AS SCHEDULE D
IN ITS ENTIRETY.
 
  Kansas Business Combination Statute. The KGCC prohibits, subject to certain
exceptions set forth therein, various business combinations with "interested
stockholders" (as hereafter described) including mergers or consolidations of
the corporation, or of any direct or indirect majority-owned subsidiary of the
corporation, for a period of three years following the date such stockholder
became an interested stockholder unless (a) prior to such date the board of
directors of the corporation approved either the business combination or the
transaction which resulted in the stockholder becoming an interested
stockholder; (b) upon consummation of the transaction which resulted in the
stockholder becoming an interested stockholder, the interested stockholder
owned at least 85% of the voting stock of the corporation outstanding at the
time the transaction commenced (determined in accordance with the KGCC); or
(c) on or subsequent to such date the business combination is approved by the
board of directors and authorized at an annual or special meeting of the
shareholders of the corporation (but not by written consent of the
shareholders), by the affirmative vote of at least 66 2/3% of the outstanding
voting shares of the corporation which are not owned by the interested
stockholder. "Interested stockholder" means, subject to certain exceptions,
any person, other than the corporation or any direct or indirect majority-
owned subsidiary of the corporation, that is (i) the owner of 15% or more of
the outstanding voting stock of the corporation; or (ii) an affiliate or
associate of the corporation and was the owner of 15% or more of the
outstanding voting stock of the corporation at any time within the three-year
period immediately prior to the date on which it is sought to be determined
whether such person is an interested stockholder, and the affiliates and
associates of such person.
 
 Other Constituency Statute
 
  Section 351.347 of the MGBCL expressly authorizes directors to consider
"non-monetary factors" when analyzing takeover bids. The factors that the
board of directors is authorized to consider include the adequacy of the
consideration offered, compared not only to the board's estimate of the value
of the corporation in a freely-negotiated sale on the liquidation value of the
corporation, but also the future value of the corporation over a period of
years as an independent entity, discounted to current value; current
political, economic and other factors bearing on security prices; whether the
bid might violate federal, state or local laws; social, legal and economic
effects on employees, suppliers, customers and others with the corporation and
the communities in which the corporation conducts its business; the financial
conditions and earnings prospects of the bidder; and the competence,
experience and integrity of the bidder.
 
  Kansas does not have a similar statute.
 
  Directors' Standard of Care and Indemnification. The KCPL Charter provides
for indemnification of KCPL's officers, directors, employees and agents, to
the fullest extent permitted under the MGBCL.
 
  The MGBCL does not provide a standard of care or otherwise fix the fiduciary
duties of corporate directors and officers. Under MGBCL (S) 351.355, a
corporation may indemnify any person who was or is a party or is threatened to
be made a party to any threatened, pending or completed action, suit or
proceeding, whether civil, criminal, administrative or investigative, other
than an action by or in the right of the corporation, by reason of the fact
that he is or was a director, officer, employee or agent of the corporation,
or is or was serving at the request of the corporation as a director, officer,
employee or agent of another corporation, partnership, joint venture, trust or
other enterprise if such person acted in good faith and in a manner such
person reasonably believed to be in or not opposed to the best interests of
the corporation, and, with respect to any criminal action or proceeding, had
no reasonable cause to believe his conduct was unlawful. A corporation may
indemnify any such person who was or is a party or is threatened to be made a
party to any threatened, pending or completed action or suit by or in the
right of the corporation to procure a judgment in its favor if such person
acted in
 
                                      75
<PAGE>
 
good faith and in a manner such person reasonably believed to be in or not
opposed to the best interests of the corporation (except in certain
circumstances where such person has been adjudged to be liable for negligence
or misconduct in the performance of his duty to the corporation). The
indemnification described above may cover not only expenses but also amounts
paid in settlements, and is not exclusive of any other rights to which such
person seeking indemnification may be otherwise entitled. In addition to the
indemnification described above, the MGBCL permits a corporation to grant
further indemnity to such person if authorized or provided for in the articles
of incorporation (or amendment thereof) or in any bylaw that has been adopted
by vote of the shareholders, except to the extent that such person's conduct
was finally adjudged to have been knowingly fraudulent, deliberately dishonest
or willful misconduct.
 
  The Western Resources Articles provide that each person who was or is made a
party or is threatened to be made a party to or is involved in any action,
administrative or investigative, by reason of the fact that he or she, or a
person of whom he or she is the legal representative, is or was a director or
officer, of Western Resources or is or was serving at the request of Western
Resources as a director, including service with respect to employee benefit
plans, whether the basis of such proceeding is an alleged action in an
official capacity as a director, officer, employee or agent or in any other
capacity while serving as a director, officer, employee or agent, shall be
indemnified and held harmless by Western Resources to the fullest extent
authorized by the KGCC.
 
  The KGCC does not provide for a standard of care or affix fiduciary duties
to corporate directors but does permit indemnification of directors. Pursuant
to KGCC (S) 17-6305, a corporation shall have power to indemnify any person
who was or is a party, or is threatened to be made a party, to any threatened,
pending or completed action, suit or proceeding, whether civil, criminal,
administrative or investigative, other than an action by or in the right of
the corporation, by reason of the fact that such person is or was a director,
officer, employee or agent of the corporation, or is or was serving at the
request of the corporation as a director, officer, employee or agent of
another corporation if such person acted in good faith and in a manner such
person reasonably believed to be in or not opposed to the best interests of
the corporation; and, with respect to any criminal action or proceeding, had
no reasonable cause to believe such person's conduct was unlawful. A
corporation may indemnify any such person who was or is a party, or is
threatened to be made a party, to any threatened, pending or completed action
or suit by or in the right of the corporation to procure a judgment in its
favor if such person acted in good faith and in a manner such person
reasonably believed to be in or not opposed to the best interests of the
corporation (except in certain circumstances where such person has been
adjudged to be liable to the corporation). The indemnification described above
may cover expenses, judgments and amounts paid in settlement, and is not
exclusive of any other rights to which such person seeking indemnification may
be otherwise entitled.
 
  Dividends; Declarations and Payments. Under MGBCL (S) 351.220, the board of
directors of a corporation may declare and the corporation may pay dividends
on its outstanding shares in cash, property, or its own shares, subject to the
following limitations and provisions, among others:
 
    (1) No dividend shall be declared or paid at a time when the net assets
  of the corporation are less than its stated capital or when the payment
  thereof would reduce the net assets of the corporation below its stated
  capital;
 
    (2) No dividend shall be declared or paid contrary to any restrictions
  contained in the articles of incorporation.
 
  Under KGCC (S) 17-6420, the directors of every corporation, subject to any
restrictions contained in its articles of incorporation, may declare and pay
dividends upon the shares of its capital stock either (1) out of its surplus,
as defined in and computed in accordance with K.S.A. (S)(S) 17-6404 and 17-
6604, or (2) in case there shall be no such surplus, out of its net profits
for the fiscal year in which the dividend is declared or the preceding fiscal
year. If the capital of the corporation shall have been diminished by
depreciation in the value of its property, or by losses, or otherwise, to an
amount less than the aggregate amount of the capital represented by the issued
and outstanding stock of all classes having a preference upon the distribution
of assets, the directors of such corporation shall not declare and pay out of
such net profits any dividends until the deficiency in the amount of capital
represented by the issued and outstanding stock of all classes having a
preference upon the distribution of assets shall have been repaired.

     SECTION 351.447 OF THE MISSOURI GENERAL AND BUSINESS CORPORATION LAW
 
(S) 351.447. CORPORATION HOLDING NINETY PERCENT OF THE SHARES OF ANOTHER MAY
MERGE.
 
  1. In any case in which at least ninety percent of the outstanding shares of
each class of a corporation or corporations is owned by another corporation
and one of the corporations is a domestic corporation and the other or others
are domestic corporations, or foreign corporations if the laws of the
jurisdictions of their incorporation permit a corporation of that jurisdiction
to merge with a corporation of another jurisdiction, the corporation having
such share ownership may either merge the other corporation or corporations
into itself and assume all of its or their obligations, or merge itself, or
itself and one or more of the other corporations, into one of the other
corporations without any vote of the shareholders of any domestic corporation
in which event the articles of merger shall state that the plan of merger has
been adopted pursuant to this section and shall set forth the resolution of
the board of directors of the parent corporation approving the plan of merger
and the date of adoption of the resolution and shall state that the parent
corporation is in compliance with the ninety percent ownership requirement of
this section and will maintain at least ninety percent ownership until the
issuance of the certificate of merger by the secretary of state; provided,
however, that if the parent corporation shall not own all of the outstanding
shares of all the subsidiary corporations, parties to a merger as aforesaid,
the plan of merger shall set forth the securities, cash, property, or rights
to be issued, paid, delivered or granted by the surviving corporation upon
surrender of each share of the subsidiary corporation or corporations not
owned by the parent corporation; and provided further, that if the parent
corporation is not the surviving corporation, the plan of merger shall include
provision for the pro rata issuance of shares of the surviving corporation to
the holders of the shares of the parent corporation on surrender of the
certificates therefor, and the articles of merger shall state that the
proposed merger has been approved by receiving the affirmative vote of holders
of at least two-thirds of the outstanding shares of the parent corporation
entitled to vote thereon at a meeting thereof duly called and held, or the
articles of merger shall state that in lieu of such required voting, the
proposed merger has been approved by the directors of each of the
corporations, that the rights and benefits of the shareholders as set forth in
section 351.093 are the same, and that the surviving corporation is solvent
and will retain the name of the parent. If the surviving corporation is a
foreign corporation, the provisions of section 351.458 shall also apply to a
merger under this section.
 
  2. If the surviving corporation is a domestic corporation, it may change its
corporate name by the inclusion of a provision to that effect in the plan of
merger adopted by the directors of the parent corporation, and upon the
effective date of the merger the name of the corporation shall be so changed
if the name is available.
 
  3. In the event all of the shares of a subsidiary domestic corporation party
to a merger effected under this section are not owned by the parent
corporation immediately prior to the merger, the surviving corporation shall,
within ten days after the effective date of the merger, notify each
shareholder of the subsidiary domestic corporation that the merger has become
effective. The notice shall be sent by certified or registered mail, return
receipt requested, addressed to the shareholder at his address as it appears
on the records of the corporation. Any shareholder of the subsidiary domestic
corporation may, within twenty days after the date of mailing of the notice,
demand in writing from the surviving corporation payment of the value of his
shares immediately prior to the merger exclusive of any element of value
arising from the expectation or accomplishment of the merger. If during a

(S) 351.455. SHAREHOLDER WHO OBJECTS TO MERGER MAY DEMAND VALUE OF SHARES,
WHEN
 
  1. If a shareholder of a corporation which is a party to a merger or
consolidation shall file with such corporation, prior to or at the meeting of
shareholders at which the plan of merger or consolidation is submitted to a
vote, a written objection to such plan of merger or consolidation, and shall
not vote in favor thereof, and such shareholder, within twenty days after the
merger or consolidation is effected, shall make written demand on the
surviving or new corporation for payment of the fair value of his shares as of
the day prior to the date on which the vote was taken approving the merger or
consolidation, the surviving or new corporation shall pay to such shareholder,
upon surrender of his certificate or certificates representing said shares,
the fair value thereof. Such demand shall state the number and class of the
shares owned by such dissenting shareholder. Any shareholder failing to make
demand within the twenty day period shall be conclusively presumed to have
consented to the merger or consolidation and shall be bound by the terms
thereof.
 
  2. If within thirty days after the date on which such merger or

certificates representing said shares. Upon payment of the agreed value the
dissenting shareholder shall cease to have any interest in such shares or in

judgment against the surviving or new corporation for the amount of such fair
value as of the day prior to the date on which such vote was taken approving
such merger or consolidation, together with interest thereon to the date of
such judgment. The judgment shall be payable only upon and simultaneously with
the surrender to the surviving or new corporations of the certificate or
certificates representing said shares. Upon the payment of the judgment, the
dissenting shareholder shall cease to have any interest in such shares, or in
the surviving or new corporation. Such shares may be held and disposed of by
the surviving or new corporation as it may see fit. Unless the dissenting
shareholder shall file such petition within the time herein limited, such
shareholder and all persons claiming under him shall be conclusively presumed
to have approved and ratified the merger or consolidation, and shall be bound
by the terms thereof.
 
  4. The right of a dissenting shareholder to be paid the fair value of his
shares as herein provided shall cease if and when the corporation shall
abandon the merger or consolidation.

     SECTION 351.407 OF THE MISSOURI GENERAL AND BUSINESS CORPORATION LAW
 
(S) 351.407. CONTROL SHARES ACQUISITION PROCEDURES--EXCEPTION.
 
  1. Unless, before the control share acquisition, the corporation's articles

share acquisitions of shares of the corporation, control shares of an issuing
public corporation acquired in a control share acquisition have only such
voting rights as are conferred by subsection 5 of this section.

may at the person's election deliver an acquiring person statement to the
issuing public corporation at the issuing public corporation's principal
office. The acquiring person statement must set forth all of the following:

    control share acquisition; and
 
      (b) Representations of the acquiring person, together with a

    that the proposed control share acquisition, if consummated, will not
    be contrary to law, and that the acquiring person has the financial
    capacity to make the proposed control share acquisition.
 
  3. (1) If the acquiring person so requests at the time of delivery of an
acquiring person statement and gives an undertaking to pay the corporation's
expenses of a special meeting, the directors of the issuing public corporation
shall within ten days thereafter call a special meeting of shareholders of the
issuing public corporation for the purpose of considering the voting rights to
be accorded the shares acquired or to be acquired in the control share
acquisition.
 
   (2) Unless the acquiring person agrees in writing to another date, the
  special meeting of shareholders shall be held within fifty days after
  receipt of the request by the issuing public corporation.
 
   (3) If no request is made, the voting rights to be accorded the shares
  acquired in the control share acquisition shall be presented to the next
  special or annual meeting of shareholders.
 
   (4) If the acquiring person so requests in writing at the time of delivery
  of its acquiring statement pursuant to this subsection, the special meeting
  must not be held sooner than thirty days after receipt by the issuing
  public corporation of the acquiring person statement.
 
  4. (1) If a special meeting is requested, notice of the special meeting of
shareholders shall be given as promptly as reasonably practicable by the
issuing public corporation to all shareholders of record as of the record date
set for the meeting, whether or not entitled to vote at the meeting.

    public corporation pursuant to this section; and
 
      (b) A statement by the board of directors of the corporation of its
    position or recommendation, or that it is taking no position or making
    no recommendation, with respect to the proposed control share
    acquisition.
 
  5. (1) Control shares acquired in a control share acquisition have the same
voting rights as were accorded the shares before the control share acquisition
only to the extent granted by resolution approved by the shareholders of the
issuing public corporation.
 
   (2) To be approved under this section, the resolution must be approved by:
 
      (a) The affirmative vote of a majority of all outstanding shares
    entitled to vote at such meeting voting by class if required by the
    terms of such shares; and
 
      (b) Also by the affirmative vote of a majority of all outstanding
    shares entitled to vote at such meeting voting by class if required by
    the terms of such shares, excluding all interested shares.
 
  6. If a shareholder shall file with the corporation, prior to or at the
meeting of shareholders at which the voting rights to be accorded any control
shares are submitted to a vote, a written objection to such voting rights
being accorded any control shares, and shall not vote in favor thereof, and
such shareholder, within twenty days after approval of voting rights being
accorded any control shares, shall make written demand on the corporation for
payment of the fair value of his shares as of the day prior to the date on
which the vote was taken approving voting rights being accorded any control
shares, the corporation shall pay to such shareholder, upon surrender of his
certificate or certificates representing such shares, the fair value of his
shares. Such demand shall state the number and class of the shares owned by
such dissenting shareholder. Any shareholder failing to make demand within the
twenty-day period provided in this subsection shall be conclusively presumed
to have consented to the control share acquisition.
 
  7. If within thirty days after the date of approval of voting rights being
accorded any control shares the value of such shares is agreed upon between
the dissenting shareholder and the corporation, payment for the shares shall
be made within ninety days after approval of voting rights being accorded any
control shares, upon the surrender of his certificate for the shares or
certificates representing such shares. Upon payment of the agreed value, the
dissenting shareholder shall cease to have any interest in such shares or in
the corporation.
 
  8. If, within the thirty-day period provided in subsection 7 of this
section, the shareholder and the corporation do not so agree, then the
dissenting shareholder may, within sixty days after the expiration of such
thirty-day period, file a petition in any court of competent jurisdiction
within the county in which the registered office of the corporation is
situated, asking for a finding and determination of the fair value of such
shares, and shall be entitled to judgment against the corporation for the
amount of such fair value as of the day prior to the date on which such vote
was taken approving such control share acquisition, together with interest
thereon to the date of such judgment. The judgment shall be payable only upon
and simultaneously with the surrender to the corporation of the certificate or
certificates representing such shares. Upon the payment of the judgment, the
dissenting shareholder shall cease to have any interest in such shares, or in
the corporation. Such shares may be held and disposed of by the corporation as
it may see fit. Unless the dissenting shareholder shall file such petition
within the time provided in this subsection, such shareholder and all persons
claiming under him shall be conclusively presumed to have consented to the
control share acquisition.
 
  9. Except as expressly provided in this section, nothing in this section
shall be construed to affect or impair any right, remedy, obligation, duty,
power, or authority of any acquiring person, any issuing public corporation,
the board of directors of any acquiring person or issuing public corporation,
or any other person under the laws of this state or any other state of the
United States of America. The requirements of this section shall be in
addition to, and shall in no way limit, the validly adopted provisions of the
articles of incorporation of any issuing public corporation.

(S) 351.015. DEFINITIONS.*
 
  (1) "Control share acquisition" means the acquisition, directly or
indirectly, by any person of ownership of, or the power to direct the exercise
of voting power with respect to, issued and outstanding control shares. For
the purposes of this chapter, shares acquired within ninety days of any
acquisition of shares or shares acquired pursuant to a plan to make a control
share acquisition are considered to have been acquired in the same
acquisition. For the purposes of this chapter, a person who acquires shares in
the ordinary course of business for the benefit of others in good faith and
not for the purpose of circumventing this chapter has voting power only of
shares in respect of which that person would be able to exercise or direct the
exercise of votes without further instruction from others. The acquisition of
any shares of an issuing public corporation does not constitute a control
share acquisition if the acquisition is consummated in any of the following
circumstances:
 
    (a) Prior to June 13, 1984;
 
    (b) Pursuant to a contract in existence prior to June 13, 1984;
 
    (c) Pursuant to a will or other testamentary disposition, the laws of
  descent and distribution or by intervivos gift where such gift is made in
  good faith and not for the purpose of circumventing section 351.407;
 
    (d) Pursuant to a public offering, a private placement, or any other
  issuance of shares by an issuing public corporation;
 
    (e) By, on behalf of, or pursuant to any benefit or other compensation
  plan or arrangement of an issuing public corporation;
 
    (f) Pursuant to the conversion of debt securities into shares of an
  issuing public corporation under the terms of such debt securities;
 
    (g) Pursuant to a binding contract, other than any contract created by,
  pursuant to, or in connection with a tender offer, whereby the holders of
  shares representing at least two-thirds of the voting power of an issuing
  public corporation, such holders acting simultaneously, agreed to sell such
  shares to any person;
 
    (h) Pursuant to the satisfaction of a pledge or other security interest
  created in good faith and not for the purpose of circumventing section
  351.407;
 
    (i) Pursuant to a merger or consolidation effected in compliance with
  sections 351.410 to 351.458 if the issuing public corporation is a party to
  the agreement of merger or consolidation;
 
    (j) Pursuant to a binding contract or other arrangement with any
  individual, foreign or domestic corporation (whether or not for profit),
  partnership, limited liability company, unincorporated society or
  association, or other entity which, at any time within one year prior to
  the acquisition in question, owned shares representing more than fifty
  percent of the voting power of the issuing public corporation;
 
    (k) By or from any person whose shares have been previously accorded
  voting rights pursuant to section 351.407; provided, the acquisition
  entitles the person making the acquisition, directly or indirectly, alone
  or as a part of a group, to exercise or direct the exercise of voting power
  of the corporation in the election of directors within a range of the
  voting power not in excess of the range of voting power associated with the
  shares to which voting rights have been previously accorded;
 
  (2) "Control shares" means shares that, except for this chapter, would have
voting power with respect to shares of an issuing public corporation that,
when added to all other shares of the issuing public corporation owned by a
person or in respect to which that person may exercise or direct the exercise
of voting power, would entitle that person, immediately after acquisition of
the shares, directly or indirectly, alone or as part of a group, to exercise
or direct the exercise of the voting power of the issuing public corporation
in the election of directors within any of the following ranges of voting
power:
 
    (a) One-fifth or more but less than one-third of all voting power;
 
    (b) One-third or more but less than a majority of all voting power;

    (c) A majority or more of all voting power; provided, however, that
  shares which the person or the group have owned or of which the person or
  the group could have exercised or directed the voting for more than ten
  years shall not be deemed to be "control shares" and shall not be
  aggregated for the purpose of determining inclusion within the above-stated
  ranges;
 
  (3) "Interested shares" means the shares of an issuing public corporation in
respect of which any of the following persons may exercise or direct the
exercise of the voting power of the corporation in the election of directors:
 
    (a) An acquiring person or member of a group with respect to a control
  share acquisition;
 
    (b) Any officer of the issuing public corporation elected or appointed by
  the directors of the issuing public corporation;
 
    (c) Any employee of the issuing public corporation who is also a director
  of such corporation;
 
  (4) "Issuing public corporation" means either a corporation incorporated
under the laws of the state of Missouri, or, subdivision (2) of section
351.690 notwithstanding, any insurance company organized pursuant to the laws
of Missouri and doing business under the provisions of chapter 376, RSMo,
provided that the bylaws of such insurance company expressly state that such
insurance company shall, for the purposes of this chapter, be included within
the definition of "issuing public corporation", that has:
 
    (a) One hundred or more shareholders;
 
    (b) Its principal place of business, its principal office, or substantial
  assets within Missouri; and
 
    (c) One of the following:
 
      a. More than ten percent of its shareholders resident in Missouri;
 
      b. More than ten percent of its shares owned by Missouri residents;
    or
 
      c. Ten thousand shareholders resident in Missouri.
 
The residence of a shareholder is presumed to be the address appearing in the
records of the corporation. Shares held by banks (except as trustee or
guardian), brokers or nominees shall be disregarded for purposes of
calculating the percentages or numbers described above.

      of shares of such class or series of stock are entitled in the event
      of any voluntary liquidation, dissolution or winding up of such

    shareholder immediately prior to the consummation of such business
    combination are entitled to receive in such business combination cash
    or other consideration for such shares in compliance with paragraphs
    (a), (b) and (c) of this subdivision;
 
      (e) After such interested shareholder's stock acquisition date and
    prior to the consummation date with respect to such business
    combination, such interested shareholder has not become the beneficial
    owner of any additional shares of voting stock of such resident

  certificate of incorporation provides otherwise; or
 
    (2) Any business combination of a resident domestic corporation whose
  certificate of incorporation has been amended to provide that such resident
  domestic corporation shall be subject to the provisions of this section,
  which did not have a class of voting stock registered with the Securities
  and Exchange Commission pursuant to Section 12 of the Exchange Act on the
  effective date of such amendment, and which is a business combination with
  an interested shareholder whose stock acquisition date is prior to the
  effective date of such amendment; or
 
    (3) Any business combination of a resident domestic corporation the
  original certificate of incorporation of which contains a provision
  expressly electing not to be governed by this section, or which adopts an
  amendment to such resident domestic corporation's bylaws prior to August 1,
  1986, expressly electing not to be governed by this section, or which
  adopts an amendment to such resident domestic corporation's bylaws,
  approved by the affirmative vote of the holders, other than interested
  shareholders and their affiliates and associates, expressly electing not to
  be governed by this section, provided that such amendment to the bylaws
  shall not be effective until eighteen months after such vote of such
  resident domestic corporation's shareholders and shall not apply to any
  business combination of such resident domestic corporation with an
  interested shareholder whose stock acquisition date is on or prior to the
  effective date of such amendment; or
 
    (4) Any business combination of a resident domestic corporation with an
  interested shareholder of such resident domestic corporation which became
  an interested shareholder inadvertently, if such interested shareholder as
  soon as practicable, divests itself of a sufficient amount of the voting
  stock of such resident domestic corporation so that it no longer is the
  beneficial owner, directly or indirectly, of twenty percent or more of the
  outstanding voting stock of such resident domestic corporation, and would
  not at any time within the five-year period preceding the announcement date
  with respect to such business combination have been an interested
  shareholder but for such inadvertent acquisition;
 
    (5) Any business combination with an interested shareholder who was the
  beneficial owner, directly or indirectly, of five percent or more of the
  outstanding voting stock of such resident domestic corporation on December
  1, 1985, and remained so to such interested shareholder's stock acquisition
  date.
