                                                                   June   , 1996
 
Dear Shareholder:
 
The  merger agreement  between Kansas  City Power  & Light  Company ("KCPL") and
UtiliCorp United Inc.  ("UCU") has been  revised to increase  the value to  KCPL
shareholders  by increasing their ownership in the combined company. As a result
of the revision to the merger agreement, the percentage interest in the combined
company held  by  KCPL shareholders  will  increase to  57%  from 55%,  and  the
percentage interest in the combined company held by UCU stockholders will change
from 45% to 43% (based, in each case, upon the capitalization of KCPL and UCU on
the date of the original merger agreement and the revised merger agreement). The
revised  terms of the merger  agreement provide for a  new structure pursuant to
which a new KCPL subsidiary will be  created which will be merged into UCU.  UCU
will  then merge with KCPL. At the  time the mergers are completed, the combined
company will change its name to Maxim Energies, Inc. ("Maxim"). Shareholders  of
UCU  will receive one share in Maxim  for each UCU share held. KCPL shareholders
will continue to hold their existing  KCPL shares (which after the mergers  will
be  called  Maxim  shares). As  a  result of  the  revised terms  of  the merger
agreement, the affirmative vote of KCPL shareholders required to approve of  the
transactions contemplated by the merger agreement has changed from two-thirds of
all  outstanding shares to a majority of the shares voting (provided a quorum is
present). The  other  significant  terms  of the  revised  mergers  will  remain
substantially the same as the original merger.
 
A  Special  Meeting  of  Shareholders  of  KCPL  is  scheduled  to  be  held  at
             on August   , 1996 at                           (the "Meeting")  to
consider  and vote upon the issuance of up  to a maximum of 54,000,000 shares of
KCPL common stock  to be  issued in the  mergers (the  "Share Issuance").  Under
Missouri  law, no separate vote of KCPL  shareholders is required to approve the
mergers. However, as it is a condition  to the closing of the mergers that  KCPL
shareholders  approve the Share Issuance,  a vote for the  Share Issuance is, in
essence, a vote for the  mergers. The attached Joint Proxy  Statement/Prospectus
describes  the recent  amendment to  the merger  agreement and  the transactions
related to it,  including certain  stock incentive  and management  compensation
plans  (the  "Plans") which  will take  effect if  the mergers  are consummated.
Please review the attached Joint Proxy Statement/Prospectus carefully.
 
   
Western Resources,  Inc.  ("Western  Resources") has  revised  its  proposal  to
acquire  KCPL  and has  announced  that it  intends  to commence  an unsolicited
exchange offer for  KCPL common stock.  Your Board of  Directors has  determined
that  Western Resources' proposal is  not in the best  interests of KCPL and its
shareholders and  has rejected  this proposal.  A complete  description of  your
Board's  rejection of  Western Resources'  latest proposal  is set  forth in the
attached Joint Proxy Statement/Prospectus. Additionally, in accordance with  its
duties  under  applicable  law,  your Board  of  Directors  will  review Western
Resources' unsolicited exchange offer if and when it is formally commenced.
    
 
For the reasons described in the attached Joint Proxy Statement/Prospectus, YOUR
BOARD OF  DIRECTORS  HAS  UNANIMOUSLY  APPROVED THE  KCPL/UCU  MERGERS  AND  THE
TRANSACTIONS  CONTEMPLATED THEREBY, AND RECOMMENDS THAT YOU VOTE FOR APPROVAL OF
THE SHARE ISSUANCE AND FOR APPROVAL OF EACH OF THE PLANS.
 
Whether or not you plan to attend the Special Meeting, PLEASE SIGN AND DATE  THE
ACCOMPANYING  WHITE PROXY  CARD AND  RETURN IT  IN THE  ENCLOSED ENVELOPE, WHICH
REQUIRES NO POSTAGE  IF MAILED IN  THE UNITED  STATES. EVEN IF  YOU SUBMITTED  A
PROXY CARD IN CONNECTION WITH THE ORIGINAL MERGER AGREEMENT, YOU WILL STILL NEED
TO  SUBMIT A NEW PROXY CARD ON THE  REVISED MERGER AGREEMENT. WE URGE YOU NOT TO
SIGN ANY PROXY CARD THAT WESTERN RESOURCES MAY SEND YOU. A KCPL shareholder  may
revoke  a proxy at any time prior to  the Meeting by delivering to the Secretary
of KCPL a notice of revocation or a duly executed proxy bearing a later date  or
by  attending the Meeting and  voting in person. Attendance  at the Meeting will
not in itself constitute revocation of a  proxy. Again, thank you very much  for
your support.
 
                                          Very truly yours,
 
                                          /s/ DRUE JENNINGS

                   NOTICE OF SPECIAL MEETING OF SHAREHOLDERS
                                AUGUST   , 1996
                             ---------------------
 
    Notice is hereby given that a Special Meeting of Shareholders of Kansas City
Power & Light Company ("KCPL") will be held at
                                  on                         , August    , 1996,
commencing at         , local time (the "Meeting"). At the Meeting, shareholders
will be asked to consider  and vote upon the  following matters, which are  more
fully described in the accompanying Joint Proxy Statement/Prospectus:
 
    1.   A proposal  to approve the issuance  (the "Share Issuance")  of up to a
       maximum of  54,000,000 shares  of common  stock, no  par value,  of  KCPL
       ("KCPL  Common Stock") pursuant to the Amended and Restated Agreement and
       Plan of Merger by and among KCPL, KC Merger Sub, Inc. ("Sub"),  UtiliCorp
       United Inc. ("UCU") and KC United Corp., dated as of January 19, 1996, as
       amended  and  restated  as  of  May 20,  1996  (as  amended,  the "Merger
       Agreement"), providing for (i) the merger of Sub with and into UCU,  with
       UCU  surviving (the "UCU  Merger"), and (ii)  immediately thereafter, the
       merger of UCU, as the corporation surviving the UCU Merger, with and into
       KCPL, with KCPL surviving (the  "Consolidating Merger" and together  with
       the  UCU Merger,  the "Mergers").  As part  of the  Consolidating Merger,
       KCPL, as the corporation surviving  in the Consolidating Merger, will  be
       renamed Maxim Energies, Inc. ("Maxim"). Pursuant to the Merger Agreement,
       each  issued and outstanding  share of common stock,  $1.00 par value per
       share, of UCU will be converted into  one share of Maxim Common Stock  in
       the  UCU Merger. Each  issued and outstanding share  of KCPL Common Stock
       held by  KCPL  shareholders will  remain  outstanding after  the  Mergers
       (except  that each such share shall be  referred to as one share of Maxim
       Common Stock).
 
    2.  A proposal to approve the Maxim Stock Incentive Plan, a copy of which is
       attached as Annex D to the accompanying Joint Proxy Statement/Prospectus.
 
    3.  A proposal to approve  the Maxim Management Incentive Compensation  Plan
       (the  "Maxim MIC Plan"),  a copy of which  is attached as  Annex E to the
       accompanying Joint Proxy Statement/Prospectus.
 
    Only shareholders of record at the close of business on June 26, 1996,  will
be  entitled to notice  of and to vote  at the Meeting or  at any adjournment or
postponement thereof. Approval  of the Share  Issuance requires the  affirmative
vote  of the holders of a majority of  the shares of KCPL Common Stock voting on
the Share  Issuance where  the total  number of  votes cast  represents over  50
percent  of all outstanding shares of KCPL  Common Stock. Under Missouri law, no
separate vote of KCPL shareholders is required to approve the Mergers.  However,
as  it  is a  condition to  the closing  of the  Mergers that  KCPL shareholders
approve of the Share  Issuance, a vote  for the Share Issuance  is in essence  a
vote  for the Mergers. The affirmative vote of  a majority of the shares of KCPL
Common Stock present and entitled to vote is required to approve the Maxim Stock
Incentive Plan and  the Maxim MIC  Plan. KCPL shareholders  are not entitled  to
dissenters' rights of appraisal.
 
    Approval  of the Share  Issuance is a  condition to the  consummation of the
Mergers. The consummation of the Mergers is also subject to the approval of  the
holders  of UCU  Common Stock, certain  required regulatory  approvals and other
conditions. If approved by the shareholders, the Maxim Stock Incentive Plan  and
the Maxim MIC Plan will be implemented only if the Mergers are consummated.

                                                                    July 1, 1996
 
Dear UtiliCorp United Inc. Stockholder,
 
    You  are cordially invited to attend  the Special Meeting of Stockholders of
UtiliCorp United Inc. ("UCU") which will be held at the Conference Center at the
Kansas City Convention Center, 14th Street between Wyandotte and Central, Kansas
City, Missouri 64105, on  Wednesday, August 14, 1996,  commencing at 2:00  p.m.,
local  time. At this important  meeting, holders of common  stock of UCU will be
asked to consider and to vote on  a proposal relating to the strategic  business
combination between UCU and Kansas City Power & Light Company ("KCPL").
 
    The merger agreement between UCU and KCPL has been amended and the structure
of  the merger has  been revised. Under the  revised terms of  the merger, a new
KCPL subsidiary will be  created, and will  be merged into UCU  with UCU as  the
surviving  corporation. UCU will then  be merged with KCPL  to form the combined
company. The combined company will be renamed Maxim Energies, Inc. ("Maxim")  at
the time of the mergers. Shareholders of UCU will receive one share of Maxim for
each  UCU share held. Shareholders of KCPL will continue to hold their shares of
KCPL, which after  the merger will  become shares of  Maxim. Under the  original
terms  of the merger, UCU  shareholders would have received  1.096 shares in the
combined company for each share held.
 
    Upon completion  of the  merger, the  holders of  UCU common  stock and  the
holders  of KCPL common stock will  own approximately 43% and 57%, respectively,
of the outstanding shares of Maxim common stock based upon the capitalization of
UCU and KCPL on  the date of  the amended merger  agreement. This represents  an
increase in value for KCPL shareholders as compared to the original merger. Your
Board  has received  a written  opinion from  its financial  advisor, Donaldson,
Lufkin & Jenrette Securities  Corporation, dated as of  the date hereof, to  the
effect  that the exchange ratio is fair, from  a financial point of view, to the
holders of UCU common stock. Other  than the changes described above, the  other
substantive terms of the merger will remain substantially the same.
 
    Your  Board believes that  this merger will  provide significant benefits to
UCU  stockholders  and  will   create  a  combined   enterprise  that  will   be
well-positioned  for an  increasingly competitive  energy environment. Strategic
advantages that Maxim will  possess include substantial operating  efficiencies,
increased  ability  to diversify  operations and  grow in  a prudent  manner and
greater financial stability.  Maxim will  also enjoy  greater opportunities  for
earnings and dividend growth through the combination of UCU's and KCPL's equity,
management, human resources and technical expertise.
 
    This  merger is subject  to certain required  regulatory approvals and other
conditions.  The  merger  will  be  consummated  shortly  after  the   necessary
regulatory  approvals  are  obtained  and other  conditions  to  the  merger are
satisfied or waived. Under Delaware law,  you do not have dissenters' rights  of
appraisal with respect to the merger.
 
    The  attached Joint Proxy Statement/Prospectus reflects the recent amendment
to the merger agreement. As you may know, the original merger agreement was  not
voted  on at  UCU's 1996 Annual  Meeting. Accordingly, the  attached Joint Proxy
Statement/Prospectus supersedes  the  Joint  Proxy  Statement/Prospectus,  dated
April  4, 1996, that  was previously sent to  you as it  relates to the proposed
merger.  You  should  review  the  attached  Joint  Proxy   Statement/Prospectus
carefully.
 
    YOUR  BOARD OF DIRECTORS HAS CAREFULLY REVIEWED AND CONSIDERED THE TERMS AND
CONDITIONS OF THE MERGER AND BELIEVES THAT IT IS FAIR AND IN THE BEST  INTERESTS
OF  UCU AND ITS  STOCKHOLDERS AND UNANIMOUSLY  RECOMMENDS THAT STOCKHOLDERS VOTE
"FOR" THE MERGER DESCRIBED IN THE ATTACHED JOINT PROXY STATEMENT/PROSPECTUS.
<PAGE>
    BECAUSE A MAJORITY  VOTE OF ALL  OUTSTANDING SHARES OF  UCU COMMON STOCK  IS
REQUIRED TO APPROVE THE MERGER, YOUR VOTE IS IMPORTANT NO MATTER HOW MANY SHARES
YOU  HOLD.  UNDER DELAWARE  LAW,  THE FAILURE  TO  VOTE, ABSTENTIONS  AND BROKER
NON-VOTES WILL  HAVE THE  SAME EFFECT  AS  VOTES CAST  AGAINST APPROVAL  OF  THE
MERGER. TO ENSURE YOUR SHARES WILL BE REPRESENTED AT THE MEETING, WHETHER OR NOT
YOU PLAN TO ATTEND, I URGE YOU TO PROMPTLY SIGN, DATE AND MAIL YOUR PROXY IN THE
ENCLOSED  SELF-ADDRESSED ENVELOPE,  WHICH REQUIRES NO  POSTAGE IF  MAILED IN THE
UNITED STATES. You may cancel your proxy by voting in person, by written  notice
to UCU's Corporate Secretary or by delivery of a later dated proxy, in each case
prior to the closing of the polls for voting at the meeting.
 
                                          Sincerely,
 
                                             /s/ Richard C. Green, Jr.
                                             RICHARD C. GREEN, JR.

    corporation in the  UCU Merger will  be merged with  and into KCPL.  The

    Stockholders  of record at the  close of business on  June 26, 1996, will be

entitled to dissenters' rights.
 
    YOUR BOARD OF DIRECTORS HAS UNANIMOUSLY APPROVED OF THE MERGER AGREEMENT AND

                       KANSAS CITY POWER & LIGHT COMPANY

                              MAXIM ENERGIES, INC.
                                ---------------
 
    This Joint Proxy  Statement/Prospectus relates to  the proposed Mergers  (as
defined herein) and certain related transactions contemplated by the Amended and
Restated  Agreement  and Plan  of  Merger, dated  as  of January  19,  1996 (the
"Original Merger  Agreement"), as  amended  and restated  on  May 20,  1996  (as
amended  and restated, the "Merger Agreement"), by and among Kansas City Power &
Light Company, a Missouri corporation ("KCPL"), KC Merger Sub, Inc., a  Delaware
corporation  and  a wholly-owned  subsidiary of  KCPL ("Sub"),  UtiliCorp United
Inc.,  a  Delaware  corporation  ("UCU"),  and  KC  United  Corp.,  a   Delaware
corporation  ("KCU"). Pursuant to the Merger  Agreement, (i) Sub will merge with
and into  UCU, with  UCU  surviving (the  "UCU  Merger"), and  (ii)  immediately
thereafter,  the surviving  corporation in  the UCU  Merger (the  "UCU Surviving
Corporation")  will  merge  with  and  into  KCPL,  with  KCPL  surviving   (the
"Consolidating  Merger,"  and  together  with the  UCU  Merger,  the "Mergers").
Pursuant to the Merger Agreement, the surviving corporation in the Consolidating
Merger will, at the effective time  of the Consolidating Merger (the  "Effective
Time"), change its name to Maxim Energies, Inc. ("Maxim"). As used in this Joint
Proxy  Statement/Prospectus, "Maxim" shall  mean KCPL after  the consummation of
the Mergers and as renamed as described above.
 
    The Mergers will be consummated on  the terms and subject to the  conditions
set  forth  in  the Merger  Agreement,  as a  result  of which  each  issued and
outstanding share  of common  stock, $1.00  par value  per share,  of UCU  ("UCU
Common  Stock") (other  than shares  of UCU  Common Stock  owned by  KCPL or UCU
either directly or through a wholly-owned  subsidiary ) shall be converted  into
and  become one  (the "Exchange  Ratio") fully  paid and  nonassessable share of
common stock, no  par value, of  KCPL ("KCPL Common  Stock"). KCPL Common  Stock
outstanding  after the consummation of the Mergers  shall be referred to in this
Joint Proxy  Statement/Prospectus  as  "Maxim Common  Stock."  Each  issued  and
outstanding  share of  KCPL Common Stock  held by KCPL  shareholders will remain
outstanding after the Mergers,  unchanged, as one share  of Maxim Common  Stock.
Based  on  the  number  of shares  outstanding  as  of the  date  of  the Merger
Agreement, the holders of KCPL Common Stock and the holders of UCU Common  Stock
will hold in the aggregate approximately 57% and 43%, respectively, of the total
number  of  shares  of  Maxim Common  Stock  outstanding  immediately  after the
Effective Time. See "THE MERGER AGREEMENT -- The Mergers."
 
    KCPL has agreed in  the Merger Agreement to  call for redemption before  the
effective  time  of  the UCU  Merger  (the  "UCU Effective  Time"),  all  of its
outstanding shares of preferred stock and preference stock (collectively,  "KCPL
Preferred  Stock") at the  applicable redemption prices  therefor, together with
all dividends accrued and  unpaid through the  applicable redemption dates.  UCU
has  agreed  under  the Merger  Agreement  to  call for  redemption  all  of the
outstanding shares of  UCU's preference stock  (cumulative), $2.05 Series  ("UCU
Preferred  Stock"), which is  the only outstanding series  of preferred stock of
UCU, on March  3, 1997  or on such  later date  as KCPL and  UCU shall  mutually
agree.  The redemption price therefor will be  $25.00 per share of UCU Preferred
Stock plus all dividends accrued and unpaid through the redemption date. It is a
condition to the closing of  the Mergers that the  UCU Preferred Stock and  KCPL
Preferred  Stock  be redeemed  before the  UCU Effective  Time. See  "THE MERGER
AGREEMENT -- The Mergers."
 
    Holders of UCU Common  Stock will not have  dissenters' rights of  appraisal
under  the Delaware General Corporation Law (the "DGCL") with respect to the UCU
Merger or any of  the other transactions contemplated  by the Merger  Agreement.
The Missouri General and Business Corporation Law (the "MGBCL") does not provide
dissenters'  rights of appraisal to holders of KCPL Common Stock with respect to
the UCU Merger because KCPL itself is  not merging with any corporation in  such
merger.  The  MGBCL also  does not  provide dissenters'  rights of  appraisal to
holders of KCPL  Common Stock  with respect to  the Share  Issuance (as  defined
herein)  or  with  respect to  the  Consolidating  Merger or  any  of  the other
transactions  contemplated  by  the  Merger  Agreement.  See  "THE  MERGERS   --
Dissenters' Rights."
                           --------------------------
 
THESE  SECURITIES HAVE  NOT BEEN APPROVED  OR DISAPPROVED BY  THE SECURITIES AND
EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION NOR HAS THE SECURITIES
   AND EXCHANGE COMMISSION OR ANY  STATE SECURITIES COMMISSION PASSED  UPON
     THE  ACCURACY OR ADEQUACY OF THIS JOINT PROXY STATEMENT/PROSPECTUS.
        ANY REPRESENTATION TO THE CONTRARY IS A CRIMINAL OFFENSE.

                  SUMMARY OF JOINT PROXY STATEMENT/PROSPECTUS
 
    THE  FOLLOWING IS A SUMMARY OF CERTAIN IMPORTANT TERMS AND CONDITIONS OF THE
MERGERS AND RELATED INFORMATION.  THIS SUMMARY DOES NOT  PURPORT TO BE  COMPLETE
AND  IS QUALIFIED IN ITS ENTIRETY BY  REFERENCE TO THE MORE DETAILED INFORMATION
APPEARING  IN  THIS  JOINT  PROXY  STATEMENT/PROSPECTUS,  THE  ANNEXES  AND  THE
DOCUMENTS  INCORPORATED HEREIN BY REFERENCE. STOCKHOLDERS ARE URGED TO READ THIS
JOINT PROXY STATEMENT/PROSPECTUS AND THE ANNEXES IN THEIR ENTIRETY.
 
THE PARTIES
 
    KCPL.  KCPL is a  low-cost electric power producer providing  energy-related
products  and  services to  customers in  its  service territory  and worldwide.
Headquartered in Kansas City, Missouri, KCPL serves the electric power needs  of
over 430,000 customers in and around the metropolitan Kansas City area. Included
in a diverse customer base are about 379,000 residences, 50,000 commercial firms
and  3,000 industrial  firms, municipalities  and other  electric utilities. Low

utility  operations,  natural  gas  gathering,  marketing  and  processing   and
independent  power projects managed  through four business  groups. UCU operates

addition,  UCU  has  ownership interests  in  17 independent  power  projects in
various locations in the United States and Jamaica. UCU also markets natural gas
in the United Kingdom  through several joint ventures,  and owns an interest  in

executive offices of  UCU are  located at 911  Main Street,  Suite 3000,  Kansas
City, Missouri 64105 and UCU's telephone number is (816) 421-6600. See "SELECTED
INFORMATION CONCERNING KCPL AND UCU -- Business of UCU."
 
THE KCPL MEETING
 
    PURPOSE.    At the  KCPL  Meeting, the  holders  of KCPL  Common  Stock will
consider and vote upon (i) a proposal to approve the Share Issuance pursuant  to
which  up to a maximum of 54,000,000 shares  of KCPL Common Stock (such stock on
or after the Mergers is referred to herein as Maxim Common Stock) will be issued
in the UCU Merger, (ii) a proposal to approve the Maxim Stock Incentive Plan and
(iii) a  proposal  to  approve  the  Maxim MIC  Plan.  Pursuant  to  the  Merger
Agreement,  the  consummation of  the Mergers  is  conditioned upon  approval of
proposal (i) above, but is not conditioned upon approval by the shareholders  of
KCPL  of any other  of the above  proposals. If approved  by the shareholders of
KCPL, each  of the  Maxim Plans  will be  implemented only  if the  transactions
contemplated by the Merger Agreement are consummated.
 
    Under  the  MGBCL, no  separate  vote of  KCPL  shareholders is  required to
approve the Mergers. However, as it is a condition to the closing of the Mergers
that KCPL  shareholders approve  of the  Share Issuance,  a vote  for the  Share
Issuance is, in essence, a vote for the Mergers.
 
                                       12
<PAGE>
    THE  KCPL BOARD, BY A UNANIMOUS VOTE, HAS APPROVED THE MERGER AGREEMENT, THE
MERGERS AND THE TRANSACTIONS CONTEMPLATED THEREBY, AUTHORIZED THE EXECUTION  AND
DELIVERY OF THE MERGER AGREEMENT, AND RECOMMENDS THAT KCPL SHAREHOLDERS VOTE FOR
APPROVAL  OF THE SHARE ISSUANCE, FOR APPROVAL  OF THE MAXIM STOCK INCENTIVE PLAN
AND FOR APPROVAL OF THE MAXIM MIC PLAN.
 
    See "MEETINGS, VOTING AND PROXIES -- The KCPL Meeting."
 
    DATE, PLACE AND TIME; RECORD DATE.  The KCPL Meeting is scheduled to be held
at                                           , on            , August   ,  1996,
commencing at     , local time. Holders of record of shares of KCPL Common Stock
at  the close  of business  on June 26,  1996 (the  "KCPL Record  Date") will be
entitled to notice and to vote at the KCPL Meeting. At the close of business  on
the  KCPL Record Date, 61,902,083 shares of KCPL Common Stock are anticipated to
be issued and outstanding and entitled to vote.
 
    VOTING RIGHTS; QUORUM; REQUIRED VOTE.  Each outstanding share of KCPL Common
Stock is entitled to one vote upon each matter presented at the KCPL Meeting.  A
majority  of the voting power of the  shares issued, outstanding and entitled to
vote, present  in  person  or  by  proxy, shall  constitute  a  quorum  for  the
transaction of business at the KCPL Meeting.
 
    Under  the  rules of  the NYSE,  the affirmative  vote of  the holders  of a
majority of the shares of KCPL Common  Stock voting on the Share Issuance  where
the  total number of  votes cast represents  over 50 percent  of all outstanding
shares of KCPL Common Stock outstanding on  the KCPL Record Date is required  to
approve the Share Issuance. Abstentions and broker non-votes will be disregarded
and  will have no effect on the vote on the Share Issuance. The affirmative vote
of a majority of the shares of KCPL Common Stock present and entitled to vote is
required to approve the Maxim Stock Incentive Plan and the Maxim MIC Plan.
 
    As of  the  KCPL Record  Date,  it is  anticipated  that the  directors  and
executive  officers of  KCPL, together  with their  affiliates as  a group, will
beneficially own  less than  1% of  the issued  and outstanding  shares of  KCPL
Common Stock.
 
    Direct  KCPL shareholder approval of the Mergers is not required under state
law for the  following reasons. The  UCU Merger is  between Sub, a  wholly-owned
subsidiary  of KCPL, and  UCU, both Delaware corporations.  Under Section 251 of
the DGCL, only stockholders of the corporations which are parties to the  merger
are  required to vote. Because KCPL is not a party to the UCU Merger, no vote of
KCPL's shareholders is  required under  Delaware law. Further,  no provision  of
Missouri law requires that KCPL shareholders vote to approve the UCU Merger. The
Consolidating  Merger  contemplated by  the Merger  Agreement is  a "short-form"
merger between KCPL and  UCU which will be  KCPL's wholly-owned subsidiary as  a
result  of the UCU  Merger. Missouri law  permits a corporation  owning at least
ninety percent of  the outstanding stock  of another corporation  to complete  a
merger  of such corporations without any  shareholder vote. In currently pending
litigation, Western Resources, Robert L. Rives and an intervening shareholder of
KCPL contend that the  Merger Agreement requires approval  of two-thirds of  all
outstanding KCPL shares.
 
    See  "MEETINGS, VOTING AND PROXIES -- The  KCPL Meeting" and "THE MERGERS --
Certain Litigations."
 
THE UCU MEETING
 
    PURPOSE.  At the UCU Meeting, the holders of UCU Common Stock will be  asked
to consider and vote upon a proposal to approve the Merger Agreement and the UCU
Merger.
 
    THE  UCU BOARD, BY A  UNANIMOUS VOTE, HAS APPROVED  THE MERGER AGREEMENT AND
THE UCU MERGER, AUTHORIZED THE EXECUTION  AND DELIVERY OF THE MERGER  AGREEMENT,
AND  RECOMMENDS THAT UCU STOCKHOLDERS VOTE  FOR APPROVAL OF THE MERGER AGREEMENT
AND THE UCU MERGER.
 
    See "MEETINGS, VOTING AND PROXIES -- The UCU Meeting."
 
                                       13
<PAGE>
    DATE, PLACE AND TIME; RECORD DATE.  The UCU Meeting is scheduled to be  held
at  the  Conference Center  at the  Kansas City  Convention Center,  14th Street
between Wyandotte and Central, Kansas City, Missouri 64105, on Wednesday, August
14, 1996, commencing at 2:00  p.m., local time. Holders  of record of shares  of
UCU  Common Stock  at the close  of business on  June 26, 1996  (the "UCU Record
Date") will be entitled to notice and to  vote at the UCU Meeting. At the  close
of  business  on the  UCU Record  Date, approximately  46,776,000 shares  of UCU
Common Stock are anticipated to be issued and outstanding and entitled to vote.
 
    VOTING RIGHTS; QUORUM; REQUIRED VOTE.  Each outstanding share of UCU  Common
Stock  is entitled to one  vote upon the Merger Agreement  and the UCU Merger. A
majority of the voting power of  the shares issued and outstanding and  entitled
to  vote,  present in  person or  by proxy,  shall constitute  a quorum  for the
transaction of business at the UCU Meeting.
 
    As provided under  the DGCL,  the Certificate  of Incorporation  of UCU,  as
amended  (the  "UCU Charter")  and the  bylaws  of UCU  (the "UCU  Bylaws"), the
affirmative vote of a majority of the outstanding shares of the UCU Common Stock
entitled to vote at the UCU Meeting  is required for the approval of the  Merger
Agreement  and the  UCU Merger. Abstentions  and broker non-votes  will have the
same effect as votes cast against approval  of the Merger Agreement and the  UCU
Merger.
 
    As  of  the  UCU Record  Date,  it  is anticipated  that  the  directors and
executive officers  of UCU,  together with  their affiliates  as a  group,  will
beneficially  own 2.2% of the issued and  outstanding shares of UCU Common Stock
entitled to vote at the UCU Meeting.
 
    See "MEETINGS, VOTING AND PROXIES -- The UCU Meeting."
 
THE MERGERS
 
    The Mergers will be consummated on  the terms and subject to the  conditions
set  forth in  the Merger  Agreement, as  a result  of which  (i) as  of the UCU
Effective Time, Sub will be merged with and into UCU, with UCU surviving in  the
UCU  Merger  and (ii)  immediately  thereafter at  the  Effective Time,  the UCU
Surviving Corporation will  be merged with  and into KCPL,  with KCPL  surviving
(and  renamed as Maxim) in the Consolidating  Merger. In addition, as of the UCU
Effective Time, (i) each issued and outstanding share of UCU Common Stock (other
than shares of UCU Common Stock owned by KCPL or UCU either directly or  through
a wholly-owned Subsidiary (as defined herein)) will be converted into and become
one  fully paid  and nonassessable  share of  Maxim Common  Stock and  (ii) each
issued and outstanding share of common stock, $1.00 par value per share, of  Sub
("Sub  Common  Stock") will  be converted  into  and become  one fully  paid and
nonassessable share  of common  stock, $0.01  par value  per share,  of the  UCU
Surviving  Corporation. Each issued  and outstanding share  of KCPL Common Stock
held by KCPL shareholders will remain outstanding after the Mergers,  unchanged,
as one share of Maxim Common Stock. Based on the number of shares of KCPL Common
Stock  and UCU Common Stock outstanding as  of the date of the Merger Agreement,
the holders of KCPL Common Stock and  the holders of UCU Common Stock will  hold
in the aggregate approximately 57% and 43%, respectively, of the total number of
shares of Maxim Common Stock outstanding immediately after the Effective Time.
 
    KCPL has agreed under the Merger Agreement to call for redemption before the
UCU  Effective Time all  of the outstanding  shares of each  series and class of
KCPL Preferred Stock at the applicable redemption prices therefor, together with
all dividends accrued and  unpaid through the  applicable redemption dates.  UCU
has  agreed  under  the Merger  Agreement  to  call for  redemption  all  of the
outstanding shares of UCU Preferred Stock, which is the only outstanding  series
or  class of preferred stock of  UCU, on March 3, 1997  or on such later date as
KCPL and UCU shall mutually agree. The redemption price therefor will be  $25.00
per  share of UCU Preferred Stock plus  all accrued and unpaid dividends through
the redemption date. It is  a condition to the closing  of the Mergers that  the
UCU  Preferred  Stock  and  KCPL  Preferred Stock  be  redeemed  before  the UCU
Effective Time.
 
    See "THE MERGER AGREEMENT -- The Mergers."
 
                                       14

CERTAIN LITIGATION
 
    The  litigation  summarized  below  concerns  the  legality  of  the  Merger
Agreement  and its adoption, and particularly relate to the requirement that the
Mergers in effect be approved by a vote  of a majority of shares of KCPL  Common
Stock  voting  (provided a  quorum  is present)  rather  than two-thirds  of all
outstanding shares of KCPL Common Stock.
 
    On May 20,  1996, KCPL commenced  litigation captioned KANSAS  CITY POWER  &
LIGHT  CO. V.  WESTERN RESOURCES,  INC, ET AL.,  C.A. No.  96-0552-CV-W-5 in the
United States  District Court  for  the Western  District of  Missouri,  Western
Division,  against Western Resources,  Inc. ("Western Resources")  and Robert L.
Rives, a KCPL shareholder.  The purpose for which  the litigation was  commenced
was  to obtain, prior to consummation of the Mergers, declaratory judgments that
the Merger Agreement  is legally  valid and its  adoption did  not constitute  a
breach of duty by KCPL's directors. On May 24, 1996, a shareholder of KCPL filed
a motion to intervene in the action as a representative of a class consisting of
similarly  situated KCPL shareholders. This  shareholder also requested leave to
file an answer to the complaint, in which he would assert counterclaims  against
KCPL  and each of its directors, who would be joined as counterclaim defendants.
The proposed counterclaims  would allege  that KCPL and  its directors  breached
fiduciary  duties  of  care, loyalty  and  disclosure in  responding  to Western
Resources'  acquisition  overtures,  including  their  adoption  of  the  Merger
Agreement;  that their actions in adopting the Merger Agreement were illegal and
ULTRA VIRES; that the adoption of  the Merger Agreement illegally deprived  KCPL
shareholders  of voting  and appraisal rights  under Missouri law;  and that the
adoption of  the Merger  Agreement was  a disproportionate  response to  Western
Resources'  acquisition offer.  On June  7, 1996,  this motion  to intervene was
granted. KCPL  believes that  the counterclaims  of the  intervenor are  without
merit and will vigorously defend.
 
    Also  on  June  7, 1996,  Western  Resources and  Rives  filed counterclaims
contending, INTER ALIA, that the Merger Agreement is illegal because it does not
require approval of  two-thirds of all  outstanding KCPL shares  and because  it
does  not provide KCPL shareholders with dissenters' rights. KCPL believes these
counterclaims to be  without merit  and will  vigorously defend.  The court  has
scheduled  a hearing on  these issues for  July 25, 1995.  If Western Resources,
Rives, and the  intervenor prevail on  these issues, the  Merger Agreement  will
require  approval of two-thirds  of all outstanding  KCPL shares and dissenters'
rights will  be available  to KCPL  shareholders. See  "THE MERGERS  --  Certain
Litigation."
 
    An  outcome favorable  to KCPL  in the above  described litigation  is not a
condition to the consummation of the Mergers. However, it is a condition to  the
consummation  of the Mergers that no  temporary restraining order or preliminary
or permanent injunction or other order by any federal or state court  preventing
consummation  of the Mergers shall have been  issued and be continuing in effect
immediately before the Effective Time. An adverse outcome to the above described
litigation which  results  in any  such  order  or injunction  may  prevent  the
consummation of the Mergers.
 
CONDITIONS TO THE MERGERS
 
    The  respective obligations  of KCPL and  UCU to consummate  the Mergers are
subject to the satisfaction of certain conditions, including the approval of the
Share Issuance by the shareholders of KCPL and the approval of the UCU Merger by
the stockholders  of  UCU; the  absence  of  any injunction  that  prevents  the
consummation  of the Mergers;  the effectiveness of  the Registration Statement;
the listing on the NYSE of the shares of Maxim Common Stock to be issued in  the
UCU   Merger;  the   receipt  of   all  material   governmental  approvals;  the
qualification of the Mergers as a pooling of interests for accounting  purposes;
obtaining  necessary permits; the performance by the other party in all material
respects, or  waiver, of  all obligations  required to  be performed  under  the
Merger  Agreement; the  accuracy of  the representations  and warranties  of the
other party set forth in the Merger Agreement as of the Closing Date (as defined
herein) (except for inaccuracies which would not reasonably be likely to  result
in  a material adverse effect to such  other party); the receipt of an officer's
certificate from the other  party stating that certain  conditions set forth  in
the  Merger Agreement have been satisfied; there having been no material adverse
effect on the other party; the

tax-free  reorganization; the receipt of  certain material third-party consents;
and the receipt of letters from  affiliates of UCU with respect to  transactions
in  securities of KCPL or  UCU. See "THE MERGER  AGREEMENT -- Conditions to Each
Party's  Obligation  to  Effect  the  Mergers"  and  "THE  MERGERS  --   Certain
Litigation."
 
EXCHANGE OF STOCK CERTIFICATES
 
    As  soon as practicable after the Effective Time, an exchange agent mutually
agreeable  to  KCPL  and  UCU  (the  "Exchange  Agent")  will  mail  transmittal
instructions  to each holder of record of shares of UCU Common Stock outstanding
at  the  UCU  Effective  Time,  advising  such  holder  of  the  procedure   for
surrendering  such  holder's  certificates (each,  an  "Old  Certificate") which
immediately prior to the UCU Effective Time represented certificates for  shares
of UCU Common Stock that were cancelled in the UCU Merger and became instead the
right  to receive shares of Maxim Common Stock. Holders of Old Certificates will
not be entitled to  receive any payment of  dividends or other distributions  on
their  Old  Certificates  until  such  certificates  have  been  surrendered for
certificates representing shares of Maxim Common Stock. Holders of shares of UCU
Common Stock should  not submit their  stock certificates for  exchange until  a
letter  of transmittal and  instructions therefor are  received. Holders of KCPL
Common Stock will  not need to  surrender their share  certificates. Issued  and
outstanding  shares of KCPL  Common Stock held by  KCPL shareholders will remain
outstanding and unchanged after the Mergers but are referred to herein as  Maxim
Common  Stock to  reflect the  combined company's  name change  to Maxim  at the
Effective Time. See "THE MERGER AGREEMENT -- The Mergers."
 
MAXIM PLANS
 
    Pursuant to the Merger Agreement, Maxim will adopt the Maxim Stock Incentive
Plan and the Maxim  MIC Plan to  replace comparable plans of  KCPL and UCU.  The
Maxim  Stock Incentive Plan is a comprehensive stock compensation plan providing
for the grant of stock options, stock appreciation rights, restricted stock  and
performance  units. The  Maxim MIC Plan  is a  short-term incentive compensation
plan providing for awards  based upon the achievement  of individual, group  and
corporate  performance goals during periods of up  to 12 months. The Maxim Plans
will only be implemented if they are  approved by KCPL shareholders at the  KCPL
Meeting and if the Mergers are consummated. For descriptions of the Maxim Plans,
see "THE MERGERS -- Maxim Plans" and "APPROVAL OF MAXIM PLANS."
 
BACKGROUND OF THE MERGERS
 
    For  a description  of the  background of the  Mergers, see  "THE MERGERS --
Background of the Mergers."
 
REASONS FOR THE MERGERS
 
    KCPL and  UCU  believe that  the  Mergers offer  significant  strategic  and
financial benefits to each company and to their respective stockholders, as well
as  to their employees and customers and  the communities in which they transact
business. These benefits include, among  others: increased ability to  diversify
into  non-regulated areas; greater efficiency; increased purchasing power; lower
future  rates  due  to  cost   savings  resulting  from  the  Mergers;   greater
coordination  of operations;  expanded management  resources and  the ability to
select leadership from a larger and more diverse management pool; increased size
and financial  stability;  enhanced  access  to new  customers  and  to  capital
markets;   stimulation  of  local  economic   growth  and  development;  reduced
administrative costs; cost savings in a  variety of other categories, which  are
estimated  to result in net savings of approximately $636 million over a 10-year
period following the Mergers as identified in a report prepared by Ernst & Young
LLP  ("Ernst  &  Young");  additional  operational  savings  identified  by  the
managements  of KCPL and UCU after the  announcement of the Original Merger; and
opportunities to enhance  revenue growth. See  "THE MERGERS --  Reasons for  the
Mergers;  Recommendations of  the Boards of  Directors," "--  Synergies from the
Mergers," "-- Additional Operational Benefits" and "-- Enhancement of  Financial
Performance."
 
                                       16
<PAGE>
    The  estimated $636 million  in net cost  savings are not  anticipated to be
realized evenly  over  the 10-year  period  following the  consummation  of  the
Mergers.  The  estimated  net cost  savings,  for  each of  the  first  10 years
following the  Mergers are  (in millions):  $19.2, $31.3,  $42.3, $49.6,  $67.7,
$82.6,  $85.6,  $82.4,  $87.7  and  $87.9,  respectively.  See  "THE  MERGERS --
Synergies from the Mergers." There can be no assurance that the combined company
will realize the cost savings estimated to occur as a result of the Mergers.  In
addition, the cost savings are subject to material assumptions. See "THE MERGERS
- --  Synergies from the  Mergers -- Material  Assumptions Underlying Cost Savings
from Synergies."

RECOMMENDATIONS OF THE BOARDS OF DIRECTORS
 
    In  considering the recommendations of the KCPL Board and the UCU Board with
respect to the  Mergers, stockholders should  be aware that  certain members  of
KCPL's  and UCU's management  and Boards of Directors  have certain interests in
the Mergers that are in  addition to the interests  of stockholders of KCPL  and
UCU generally. See "THE MERGERS -- Conflicts of Interest."
 
   
    KCPL.   The KCPL  Board, by a  unanimous vote, has  approved and adopted the
Merger  Agreement,  the  Mergers  and  the  transactions  contemplated  thereby,
believes  that the terms of  the Mergers are fair to,  and in the best interests
of, KCPL's shareholders and  recommends that the shareholders  of KCPL vote  FOR
approval  of the Share Issuance and FOR approval of each of the Maxim Plans. The
KCPL Board approved and  adopted the Merger Agreement  after consideration of  a
number  of factors described under  the heading "THE MERGERS  -- Reasons for the
Mergers; Recommendations  of the  Boards of  Directors" including  the  Proposed
Western  Resources Offer and the June  17 Announcement (each as defined herein).
In addition, on  June 24,  1996, the  KCPL Board,  after careful  consideration,
rejected  the Western Resources Offer contained in the June 17 Announcement. See
"THE MERGERS --  Background of  the Mergers" and  "-- Reasons  for the  Mergers;
Recommendations of the Board of Directors."
    
 
    UCU.   The  UCU Board,  by a  unanimous vote,  has approved  and adopted the
Merger Agreement and  the transactions contemplated  thereby, believes that  the
terms  of  the UCU  Merger are  fair to,  and  in the  best interests  of, UCU's
stockholders and recommends that  the stockholders of UCU  vote FOR approval  of
the  Merger Agreement and the UCU Merger. The UCU Board approved and adopted the
Merger Agreement after consideration of a number of factors described under  the
heading  "THE MERGERS -- Reasons for  the Mergers; Recommendations of the Boards
of Directors."
 
OPINIONS OF FINANCIAL ADVISORS
 
   
    KCPL.  On May 20, 1996,  Merrill Lynch, Pierce, Fenner & Smith  Incorporated
("Merrill  Lynch") delivered  its oral  opinion, which  opinion was subsequently
confirmed in written opinions  dated as of May  20, 1996 and as  of the date  of
this  Joint Proxy Statement/Prospectus, to the KCPL Board to the effect that, as
of such dates and based upon the assumptions made, matters considered and limits
of review as  set forth in  such opinions,  the proposed Exchange  Ratio of  one
share  of Maxim Common Stock for each share  of UCU Common Stock pursuant to the
UCU Merger is fair to the holders of shares of KCPL Common Stock (other than UCU
and its affiliates) from a financial point of view. In arriving at its  opinions
dated   as  of  May  20,   1996  and  as  of  the   date  of  this  Joint  Proxy
Statement/Prospectus, the KCPL Board did not  ask Merrill Lynch to consider  the
Proposed  Western Resources  Offer or  the Proposed  Western Resources  Offer as
amended  to  reflect  the   terms  contained  in   the  June  17   Announcement,
respectively,  and Merrill  Lynch did not  do so.  The full text  of the written
opinion  of  Merrill  Lynch,  dated  as   of  the  date  of  this  Joint   Proxy
Statement/Prospectus,  which sets forth the assumptions made, matters considered
and limits of the review undertaken in connection with the opinion, is  attached
hereto  as Annex B and is incorporated herein by reference. HOLDERS OF SHARES OF
KCPL COMMON STOCK ARE URGED TO, AND  SHOULD, READ SUCH OPINION IN ITS  ENTIRETY.
See "THE MERGERS -- Opinion of KCPL's Financial Advisor" and Annex B.
    
 
                                       17
<PAGE>
    UCU.   On May 19, 1996,  Donaldson, Lufkin & Jenrette Securities Corporation
("DLJ") delivered its oral opinion, which opinion was subsequently confirmed  in
a  written opinion dated as of May 19,  1996 and a further written opinion dated
the date of  this Joint Proxy  Statement/Prospectus, to the  effect that, as  of
such  dates, and subject to the  assumptions made, matters considered and limits
of the review undertaken, as set forth  in such opinions, the Exchange Ratio  is
fair,  from a financial point of view, to holders of UCU Common Stock. A copy of
the written  opinion  of  DLJ,  dated  as  of  the  date  of  this  Joint  Proxy
Statement/Prospectus,  which sets forth the assumptions made, matters considered
and limits of the review undertaken in connection with the opinion, is  attached
hereto  as Annex C and is incorporated herein by reference. HOLDERS OF SHARES OF
UCU ARE  URGED TO,  AND SHOULD,  READ SUCH  OPINION IN  ITS ENTIRETY.  See  "THE
MERGERS -- Opinion of UCU's Financial Advisor" and Annex C.
 
WESTERN RESOURCES' PROPOSALS
 
   
    On April 14, 1996 Western Resources delivered an unsolicited proposal to the
KCPL  Board  pursuant  to  which  Western Resources  would  acquire  all  of the
outstanding shares of KCPL Common Stock in exchange for Western Resources Common
Stock (as  defined herein)  valued at  $28.00 per  share of  KCPL Common  Stock,
subject to a "collar" limiting the amount of Western Resources Common Stock that
holders  of KCPL Common Stock would receive  for each share of KCPL Common Stock
to no more than 0.985 shares and no  less than 0.833 shares. On April 21,  1996,
the  KCPL Board, after  careful consideration, rejected  such proposal. On April
22, 1996, Western Resources filed preliminary materials with the SEC relating to
the Proposed Western Resources Offer  pursuant to which Western Resources  would
acquire  the outstanding  shares of  KCPL Common Stock  for $28.00  per share of
Western Resources  Common Stock,  subject to  the "collar"  described above  and
numerous  other conditions. On May 6,  1996, Western Resources announced that it
was changing the minimum number of shares of Western Resources Common Stock that
KCPL shareholders would receive for each  share of KCPL Common Stock from  0.833
to  0.91  shares.  On  June  17,  1996,  Western  Resources  made  the  June  17
Announcement (as defined herein) pursuant to which it increased the price in its
offer to merger with KCPL to $31.00  of Western Resources Common Stock for  each
share  of KCPL Common Stock, subject to  a "collar" pursuant to which each share
of KCPL Common Stock would  be exchanged for no more  than 1.1 and no less  than
0.933  shares  of Western  Resources  Common Stock.  On  June 19,  1996, Western
Resources amended the Proposed Western  Resources Offer to reflect the  increase
in  price and change in  the "collar" announced in  the June 17 Announcement. On
June 24, 1996, the KCPL Board, after careful consideration, rejected the Western
Resources offer contained in the June 17 Announcement.
    
 
   
    As of the date of  this Joint Proxy Statement/Prospectus, Western  Resources
has not formally commenced the Proposed Western Resources Offer.
    
 
    See "THE MERGERS -- Background of the Mergers."
 
CONFLICTS OF INTEREST
 
    In  considering the recommendations of the KCPL Board and the UCU Board with
respect to the  Mergers, stockholders should  be aware that  certain members  of
KCPL's  and UCU's management  and Boards of Directors  have certain interests in
the Mergers that are in  addition to the interests  of stockholders of KCPL  and
UCU generally.
 
    BOARD  OF  DIRECTORS.   The  Merger  Agreement  provides that  the  board of
directors of Maxim  (the "Maxim Board")  will consist of  18 directors, nine  of
whom  will  be the  then existing  directors  of KCPL  immediately prior  to the
Effective Time and nine of whom will be designated by UCU. To date, UCU has  not
determined which individuals, in addition to Richard C. Green, Jr., the Chairman
of  the Board and Chief Executive Officer of UCU, will be its designees to serve
as directors  of  Maxim as  of  the Effective  Time.  However, it  is  currently
anticipated  that the directors  of UCU immediately prior  to the Effective Time
will serve as UCU's designees to the Maxim Board. See "THE MERGERS --  Conflicts
of Interest -- Board of Directors."
 
                                       18
<PAGE>
   
    EMPLOYMENT AGREEMENTS.  Each of A. Drue Jennings, the Chairman of the Board,
President  and Chief Executive Officer of KCPL, and Mr. Green will enter into an
employment agreement with Maxim to become effective upon the consummation of the
Mergers (each, an "Employment Agreement"). The term of each Employment Agreement
shall last until the  fifth anniversary of the  Effective Time. Pursuant to  Mr.
Jennings'  Employment Agreement, from  the Effective Time until  the date of the
annual meeting of shareholders of Maxim  that occurs in 2002, Mr. Jennings  will
serve  as  Chairman  of  Maxim,  and  thereafter  until  the  expiration  of his
Employment Agreement will serve  as Vice Chairman of  Maxim. From the  Effective
Time  until the  earlier of  the annual  meeting of  shareholders of  Maxim that
occurs in 2002 or the date Mr.  Jennings ceases to serve as Chairman, Mr.  Green
will serve as Vice Chairman and Chief Executive Officer of Maxim, and thereafter
until  the expiration  of his  Employment Agreement  will serve  as Chairman and
Chief Executive Officer. Pursuant to the Employment Agreements, Messrs. Jennings
and Green  will  receive  salary,  bonus and  other  compensation  as  shall  be
determined  by the  Maxim Board,  but not less  than either  received before the
Effective Time. Based  upon current  compensation levels,  Messrs. Jennings  and
Green would receive an annual base salary of $630,000 and be eligible for annual
bonuses  of between $0 and approximately $1,040,000, depending upon performance.
The Employment Agreements provide for the payment by Maxim of severance benefits
in the event of the termination  of employment by the Executive under  specified
circumstances.  Based  upon  the  salary  levels  currently  in  effect,  if the
employment of Mr. Jennings or Mr. Green is terminated immediately following  the
consummation  of  the  Mergers  under circumstances  entitling  them  to receive
severance benefits, they would be entitled  to a severance payment ranging  from
approximately  $1.9  million  to $3.1  million,  plus certain  other  amounts in
respect of bonuses and benefits. No other  officers or directors of KCPL or  UCU
have entered into employment or other agreements with Maxim. See "THE MERGERS --
Conflicts of Interest -- Employment Agreements."
    
 
    EMPLOYEE PLANS AND SEVERANCE ARRANGEMENTS.  Under certain agreements entered
into  by KCPL  and UCU,  certain officers  of KCPL  and UCU  may be  entitled to
payment of certain severance benefits  upon termination of employment  following
consummation  of the Mergers. In addition, stock options outstanding under UCU's
Amended and Restated 1986 Stock Incentive Plan (the "UCU Plan") and the UCU 1986
Stock Incentive Plan (the "UCU 1986 Plan") vested upon execution of the Original
Merger Agreement. Restricted stock outstanding under the UCU 1986 Plan will vest
upon consummation of the UCU Merger. The aggregate amount which could be payable
under certain circumstances upon termination of employment after the Mergers  to
the  five most  highly compensated executive  officers of KCPL  who have entered
into the "KCPL Severance Agreements"  (as defined herein) is approximately  $6.1
million.  In  addition,  an  aggregate  of  approximately  $450,000  in deferred
compensation  would  be  payable  to  these  individuals  upon  termination   of
employment  after the Mergers. The aggregate amount which could be payable under
certain circumstances upon termination  of employment after  the Mergers to  the
five most highly compensated executive officers of UCU who have entered into the
"UCU  Severance Agreements" (as  defined herein) is  approximately $4.9 million.
Approximately 290,000 options  vested for  such officers upon  execution of  the
Merger Agreement. Approximately 71,800 shares of restricted stock will vest upon
consummation  of the UCU  Merger. See "THE  MERGERS -- Conflicts  of Interest --
Employee Plans and Severance Arrangements."
 
    INDEMNIFICATION.  The parties have agreed in the Merger Agreement that Maxim
will indemnify, to the fullest extent  permitted by applicable law, the  present
and  former officers,  directors and  employees of  each of  the parties  to the
Merger Agreement  or  any of  their  Subsidiaries (as  defined  herein)  against
certain  liabilities (i)  arising out  of actions  or omissions  occurring at or
prior to the Effective Time that arise from  or are based on such service as  an
officer,  director or  employee or  (ii) that are  based on  or arise  out of or
pertain to  the  transactions  contemplated  by the  Merger  Agreement,  and  to
maintain  policies of directors' and officers'  liability insurance for a period
of not less than six years after  the Effective Time, provided that Maxim  shall
not  be required to expend in any year an amount in excess of 200% of the annual
aggregate premium currently  paid by  KCPL and UCU  for such  insurance. To  the
fullest  extent permitted by law, from and  after the Effective Time, all rights
to indemnification  existing in  favor of  the employees,  agents, directors  or
officers of KCPL,
 
                                       19
<PAGE>
UCU  and their respective Subsidiaries with  respect to their activities as such
prior to  the  Effective Time,  as  provided  in their  respective  articles  of
incorporation  and bylaws in effect on January  19, 1996, or otherwise in effect
on January 19, 1996, shall survive the Mergers and shall continue in full  force
and  effect for a period of not less than six years from the Effective Time. See
"THE MERGERS  --  Conflicts of  Interest  -- Indemnification"  and  "THE  MERGER
AGREEMENT -- Directors' and Officers' Indemnification."
 
EMPLOYEE STOCK OPTIONS
 
    All  stock options to  acquire UCU Common Stock  under the existing employee
stock incentive plans of UCU that are outstanding at the UCU Effective Time will
be converted into options to  buy Maxim Common Stock,  and the number of  shares
and  exercise  price under  such options  will,  in most  cases, be  adjusted to
reflect the Exchange  Ratio. See "THE  MERGERS -- Maxim  Plans" and "THE  MERGER
AGREEMENT -- Benefit Plans."
 
MANAGEMENT OF MAXIM
 
    In connection with the Mergers, the Maxim Board, at the Effective Time, will
consist  of 18 persons, nine of whom will be the then existing directors of KCPL
immediately prior to the Effective Time, and nine of whom will be designated  by
UCU.  At the Effective Time, A. Drue  Jennings will become the Chairman of Maxim
and Richard C. Green, Jr., will become Vice Chairman and Chief Executive Officer
of Maxim.  Robert K.  Green,  brother of  Richard C.  Green,  Jr., will  be  the
president  of  Maxim and  Marcus Jackson  will serve  as Maxim's  executive vice
president and chief operating officer. Robert K. Green is currently president of
UCU and Marcus Jackson is senior  vice president and chief operating officer  of
KCPL.  See  "THE  MERGERS --  Employment  Agreements" and  "MAXIM  FOLLOWING THE
MERGERS -- Management of Maxim."
 
RIGHTS TO TERMINATE, AMEND OR WAIVE CONDITIONS
 
    The  Merger  Agreement  may  be  terminated  under  certain   circumstances,
including:  by mutual consent of  KCPL and UCU; by any  party if the Mergers are
not consummated by December 31, 1997 (which date may be extended to December 31,
1998 under certain  circumstances); by  any party if  the requisite  stockholder
approvals  are  not obtained  or  if any  state or  federal  law or  court order
prohibits consummation of the Mergers; by a non-breaching party if there  occurs
a  material breach of the Merger Agreement which is not cured within 20 days; or
by either party, under  certain circumstances, as a  result of a more  favorable
third-party  tender offer or business combination  proposal with respect to such
party. The Merger Agreement requires that termination fees be paid under certain
circumstances, including if there  is a material, willful  breach of the  Merger
Agreement  or if,  under certain  circumstances, a  business combination  with a
third party is entered into or consummated within two and one-half years of  the
termination  of the Merger Agreement. The aggregate termination fees under these
provisions may not exceed $58,000,000. See "THE MERGER AGREEMENT --  Termination
Fees."
 
    The  Merger  Agreement may  be amended  by  the Boards  of Directors  of the
parties at any time before  or after the approval of  the Share Issuance by  the
shareholders  of KCPL and the approval of  the UCU Merger by the stockholders of
UCU, but after such approvals, no amendment may be made which alters or  changes
(i)  the amount or  kind of shares, rights  or the manner  of conversion of such
shares, or  (ii)  the terms  or  conditions of  the  Merger Agreement,  if  such
alteration  or change,  alone or  in the  aggregate, would  materially adversely
affect the  rights of  the KCPL  shareholders or  UCU stockholders,  except  for
alterations  or  changes that  could  otherwise be  adopted  by the  Maxim Board
without the further approval of such stockholders. See "THE MERGER AGREEMENT  --
Amendment and Waiver."
 
    At  any  time  prior to  the  Effective  Time, to  the  extent  permitted by
applicable law, the conditions to KCPL's or UCU's obligations to consummate  the
Mergers may be waived by the other party. Any determination to waive a condition
would    depend   upon   the   facts   and   circumstances   existing   at   the
 
                                       20
<PAGE>
time of such waiver and would be made by the waiving party's Board of Directors,
exercising its fiduciary  duties to such  party and its  stockholders. See  "THE
MERGER AGREEMENT -- Amendment and Waiver."
 
CERTAIN FEDERAL INCOME TAX CONSEQUENCES
 
    The  consummation of the Mergers is conditioned  upon the receipt by KCPL of
an opinion from Skadden,  Arps, Slate, Meagher &  Flom ("Skadden Arps") and  the
receipt  by UCU of  an opinion from  Blackwell Sanders Matheny  Weary & Lombardi
L.C. ("Blackwell Sanders") substantially to the effect that (i) the Mergers will
qualify as a reorganization under Section 368(a) of the Internal Revenue Code of
1986, as  amended (the  "Code"), (ii)  no gain  or loss  will be  recognized  by
stockholders  of UCU who exchange their shares of UCU Common Stock for shares of
Maxim Common Stock as a result of the Mergers, and (iii) no gain or loss will be
recognized by shareholders of KCPL as a result of the Mergers. See "THE  MERGERS
- -- Certain Federal Income Tax Consequences."
 
    STOCKHOLDERS  OF KCPL AND  UCU ARE URGED  TO CONSULT THEIR  OWN TAX ADVISORS
WITH RESPECT TO THE SPECIFIC TAX CONSEQUENCES TO THEM OF THE MERGERS,  INCLUDING
THE   APPLICATION  TO  THEM  AND  POSSIBLE  EFFECT  UPON  THEM  OF  ANY  PENDING
LEGISLATION, THE ALTERNATIVE MINIMUM  TAX, AND STATE,  LOCAL AND FOREIGN  INCOME
AND OTHER TAX LAWS.
 
MAXIM FOLLOWING THE MERGERS
 
    At the Effective Time, KCPL will change its name to Maxim or such other name
as  KCPL and  UCU shall  mutually agree.  The headquarters  of Maxim  will be in
Kansas City, Missouri. The utility businesses of Maxim will serve  approximately
860,000  electric customers and  800,000 gas customers  in portions of Missouri,
Kansas, Colorado, Iowa, Michigan, Minnesota, Nebraska, West Virginia and British
Columbia. A joint venture in Australia will serve approximately 520,000 electric
customers. The business of Maxim will primarily consist of owning and  operating
electric  and gas utilities, including  interests in several international joint
ventures, and also owning and operating various non-utility subsidiaries.
 
    Pursuant  to   the  Merger   Agreement,  Maxim   shall  provide   charitable
contributions  and community support within the service areas of KCPL and UCU at
levels substantially comparable  to the levels  of charitable contributions  and
community support provided by such parties within their service areas within the
two-year period immediately prior to the Effective Time.
 
    See "MAXIM FOLLOWING THE MERGERS."
 
REGULATORY MATTERS
 
    The  approval of the  Nuclear Regulatory Commission  under the Atomic Energy
Act of 1954, as amended (the "Atomic Energy Act"), the Federal Energy Regulatory
Commission (the "FERC") under the Federal Power Act, as well as the approval  of
the utility regulators in Missouri, Kansas, Colorado, Iowa, Michigan, Minnesota,
West  Virginia and British  Columbia under applicable  state and provincial laws
and the expiration  or termination of  the applicable waiting  period under  the
Hart-Scott-Rodino  Antitrust  Improvements Act  of  1976, as  amended  (the "HSR
Act"), are  required  in order  to  consummate  the Mergers.  In  addition,  the
approval  of governmental authorities in Australia and New Zealand are required.
The receipt of all of these approvals  is presently anticipated to occur by  the
second quarter of 1997.
 
    KCPL  and UCU intend to  request a "no-action" letter  from the staff of the
SEC, confirming  their view  that (i)  the Mergers  will not  require the  prior
approval  of the SEC pursuant  to Section 9(a)(2) of  the Public Utility Holding
Company Act of  1935 (the  "1935 Act") and  (ii) following  consummation of  the
Mergers, Maxim will be a holding company entitled to claim exemption pursuant to
Rule  10 from all provisions of the 1935 Act. In the event that the staff of the
SEC does not concur with this view,  KCPL and UCU will file an application  with
the  SEC  for the  necessary  approvals and  exemptions  in connection  with the
Mergers.
 
                                       21
<PAGE>
    KCPL and  UCU possess  municipal franchises  and environmental  permits  and
licenses  that require the consent of the licensor to the Mergers or may need to
be renewed  or  replaced as  a  result of  the  Mergers. Neither  KCPL  nor  UCU
anticipate  any difficulties  at the  present time  in obtaining  such consents,
renewals, replacements or transfers.
 
    Assuming the requisite  regulatory approvals are  obtained, Maxim's  utility
operations  will  be  subject  to regulation  by  state  and  provincial utility
regulators in  Missouri,  Kansas,  Colorado,  Iowa,  Michigan,  Minnesota,  West
Virginia and British Columbia and certain non-utility operations will be subject
to  regulation  in  Oklahoma,  South  Dakota  and  Texas.  In  addition, certain
investment activities of Maxim will be subject to the jurisdiction of regulatory
authorities in Australia and New Zealand.
 
    Under the Merger Agreement, KCPL and UCU have agreed to use all commercially
reasonable efforts  to  obtain  all  governmental  authorizations  necessary  or
advisable  to consummate or  effect the transactions  contemplated by the Merger
Agreement. Various parties may seek intervention in these proceedings to  oppose
the  Mergers  or  to  have  conditions imposed  upon  the  receipt  of necessary
approvals. While  KCPL and  UCU believe  that they  will receive  the  requisite
regulatory approvals for the Mergers, there can be no assurance as to the timing
of  such approvals or  the ability of  such parties to  obtain such approvals on
satisfactory terms or otherwise.  It is a condition  to the consummation of  the
Mergers  that final  orders approving the  Mergers be obtained  from the various
federal and state regulators described above on terms and conditions which would
not have,  or foreseeably  could not  have,  a material  adverse effect  on  the
business,  assets, financial condition or results of operations of Maxim and its
prospective subsidiaries  taken  as  a  whole,  or  which  would  be  materially
inconsistent  with  the  agreements  of  the  parties  contained  in  the Merger
Agreement. There can be  no assurance that any  such approvals will not  contain
terms  or conditions that cause such approvals to fail to satisfy such condition
to the consummation of the Mergers.
 
    See "THE MERGERS -- Regulatory Matters."
 
ACCOUNTING TREATMENT
 
    KCPL and  UCU believe  that the  Mergers will  be treated  as a  pooling  of
interests  for accounting purposes.  See "THE MERGERS  -- Accounting Treatment."
The receipt  by  each  of  KCPL  and UCU  of  a  letter  from  their  respective
independent  accountants, stating that the transaction will qualify as a pooling
of interests, is a condition to the consummation of the Mergers. This  condition
may  be waived, but KCPL and UCU presently  have no intention to do so. See "THE
MERGER AGREEMENT  --  Conditions  to  Each  Party's  Obligation  to  Effect  the
Mergers."
 
DISSENTERS' RIGHTS
 
    Holders  of KCPL Common Stock and UCU Common Stock will not have dissenters'
rights of appraisal with respect to the Mergers. See "THE MERGERS -- Dissenters'
Rights."
 
    Under the Original  Merger Agreement, dissenters'  rights of appraisal  were
available  to  shareholders of  KCPL. In  currently pending  litigation, Western
Resources, Mr.  Rives,  and an  intervening  KCPL shareholder  contend  that  by
adopting  the Merger Agreement, KCPL has illegally deprived KCPL shareholders of
dissenters' rights. See "THE MERGERS -- Certain Litigation."
 
DIVIDENDS
 
    KCPL AND UCU.  Pursuant to the  Merger Agreement, each of KCPL and UCU  have
agreed  not to,  and have  agreed not  to permit  any of  their Subsidiaries to,
declare or pay any dividends on, or make other distributions in respect of,  any
of  its capital stock, other  than (i) to such party  or any of its wholly-owned
Subsidiaries, (ii) dividends required to be  paid on the UCU Preferred Stock  or
series or class of KCPL Preferred Stock, (iii) regular quarterly dividends to be
paid  on  KCPL Common  Stock and  UCU Common  Stock  not to  exceed 105%  of the
dividends for the comparable period of the prior fiscal year, and (iv) dividends
by Aquila Gas Pipeline Corporation ("AGP"), UtiliCorp U.K., Inc., UtiliCorp U.K.
Limited, West Kootenay Power Ltd., UtiliCorp N.Z., Inc. and any Subsidiaries  of
such  entities. KCPL currently pays  an annual dividend of  $1.56 per share, and
UCU currently  pays an  annual dividend  of  $1.76 per  share. See  "THE  MERGER
AGREEMENT -- Certain Covenants."

    MAXIM.    The dividend  policy  of Maxim  will  be determined  upon periodic
evaluation by  the  Maxim Board  of  Maxim's results  of  operations,  financial
condition, capital requirements and such other considerations as the Maxim Board
considers  relevant in accordance with applicable laws. Although there can be no
assurance, it  is  the intention  of  KCPL and  UCU,  subject to  the  fiduciary
obligations  of the Maxim Board,  that the initial annual  dividend per share of
Maxim Common  Stock following  the Effective  Time will  be at  least $1.85  per
share.  See "MAXIM FOLLOWING THE MERGERS -- Dividends" and "DESCRIPTION OF MAXIM
COMMON STOCK."
 
COMPARISON OF STOCKHOLDERS' RIGHTS
 
    As a result  of the  UCU Merger,  holders of  UCU Common  Stock will  become
shareholders of KCPL (to be renamed Maxim upon consummation of the Consolidating
Merger),  a Missouri corporation. Such holders will have certain rights as Maxim
shareholders that  are different  than they  had as  stockholders of  UCU,  both
because  of the  differences between  KCPL's Restated  Articles of Consolidation
(the "KCPL Charter" or, after the  name change, the "Maxim Charter") and  KCPL's
Bylaws (the "KCPL Bylaws" or, after the name change, the "Maxim Bylaws"), on the
one hand, and the UCU Charter and the UCU Bylaws, on the other hand, and because
of  differences between Missouri and Delaware  corporation law. For a comparison
of the charter and bylaw provisions of KCPL and UCU and of Missouri and Delaware
law, see "COMPARISON OF STOCKHOLDERS' RIGHTS."

SELECTED UNAUDITED PRO FORMA FINANCIAL DATA
 
    The  following selected  unaudited pro forma  financial information combines
the historical consolidated balance sheets and statements of income of KCPL  and
UCU,  including  their  respective  subsidiaries,  after  giving  effect  to the
Mergers. The unaudited pro forma combined balance sheet data at March 31,  1996,
and  December 31, 1995, 1994 and 1993 give  effect to the Mergers as if they had
occurred at the respective balance sheet dates. The unaudited pro forma combined
statements of  income for  each of  the  years in  the three-year  period  ended
December  31, 1995, and the three-month period ended March 31, 1996, give effect
to the Mergers as if they had occurred at January 1, 1993. These statements  are
prepared  on the basis of  accounting for the Mergers  as a pooling of interests
and are based on the assumptions set  forth in the notes thereto. The  following
information is not necessarily indicative of the financial position or operating
results that would have occurred had the Mergers been consummated on the date as
of  which, or at the  beginning of the periods for  which, the Mergers are being
given effect nor  is it necessarily  indicative of future  operating results  or
financial  position. See "UNAUDITED PRO FORMA COMBINED FINANCIAL INFORMATION" in

NOTES TO SELECTED HISTORICAL AND PRO FORMA DATA
 
    The following notes explain by  company certain yearly activities that  have
impacted income or earnings:
 
    KCPL:
 
    (a)  In 1994, KCPL  recorded a $22.5  million expense for  a voluntary early
       retirement program.
 
    (b) In  1992, KCPL's  revenues were  adversely impacted  by abnormally  cool
       summer temperatures.
 
    UCU:
 
    (c)  In 1995, UCU changed its method  of accounting for domestic natural gas
       trading  operations  to  the   mark-to-market  method.  This  change   in
       accounting  increased  operating  revenues  and  operating  income before
       income taxes by $29.8  million, earnings available  for common shares  by
       $18.3  million  and  total  assets  by  $201.9  million.  This  change in
       accounting has been reflected from January 1, 1995. The pro forma  effect
       on  prior periods  is not  material. Also in  1995, UCU  recorded a $34.6
       million  pretax  charge  related  to  impaired  assets  and  adoption  of
       Statement of Financial Accounting Standards No. 121.
 
    (d) In 1993, Aquila Energy Corporation ("Aquila"), a wholly-owned subsidiary
       of  UCU,  recorded a  $69.8 million  restructuring charge  against pretax
       earnings related to a change in strategic direction. Aquila also sold 18%
       of AGP, its then wholly-owned  subsidiary, in an initial public  offering
       resulting in a non-taxable gain of $47.8 million.
 
    (e)  In 1992, Aquila recorded a $17.7 million charge against pretax earnings
       for improper payments by former employees.
 
    Other Notes:
 
    (f) On February 7,  1996, UCU increased its  quarterly cash dividend on  the
       UCU  Common Stock to $.44  per share from $.43  per share. The annualized
       rate is now $1.76 per share of UCU Common Stock.
 
    (g) For  purposes of  computing  the ratio  of  earnings to  fixed  charges,
       "earnings" consists of net income plus interest charges, income taxes and
       the  estimated interest component  of rents. "Fixed  charges" consists of
       interest charges and the estimated interest component of rents. The ratio
       shown for  the three-month  period is  based on  information for  the  12
       months ended March 31, 1996.
 
    (h)  For purposes of computing  the ratio of earnings  to fixed charges plus
       preferred dividend requirements, "earnings"  consists of net income  plus
       interest  charges, income taxes  and the estimated  interest component of
       rents. "Fixed charges"  consists of  interest charges  and the  estimated
       interest  component of rents.  "Preferred dividend requirements" consists
       of the calculated pre-tax preferred dividend requirement. The ratio shown
       for the three-month  period is  based on  information for  the 12  months
       ended March 31, 1996.
 
    (i) Includes notes payable to banks and others, commercial paper borrowings,
       and the current portion of long-term debt.
 
    (j)   Pro forma per common share amounts give effect to the exchange of each
       share of UCU  Common Stock  outstanding into  one share  of Maxim  Common
       Stock.  See "THE  MERGER AGREEMENT  -- The  Mergers" in  this Joint Proxy
       Statement/Prospectus. Pro forma per common share amounts do not, however,
       give   effect    to    the    synergies    of    the    transaction    or
 
                                       27

       transaction  costs. For a description of  the synergies, see "THE MERGERS
       -- Reasons for the Mergers;  Recommendations of the Boards of  Directors"
       in this Joint Proxy Statement/ Prospectus.
 
    (k) See Note 4 to Notes to Unaudited Pro Forma Combined Financial Statements
       for  a discussion  of the  redemption of  certain preferred  stock issues
       prior to consummation of the Mergers.
 
COMPARATIVE PER SHARE DATA
 
    Set forth below are earnings, cash dividends and book value per common share
data of KCPL and UCU, on both historical and pro forma combined bases. Pro forma
combined earnings per share is derived  from the pro forma combined  information
presented  elsewhere herein, which gives effect to the Mergers under the pooling
of interests accounting method and combines the results of KCPL and UCU for  the
periods  presented. Pro forma  combined cash dividends  per share reflect KCPL's
and UCU's cash  dividends in the  periods indicated. The  information set  forth
below  should  be  read in  conjunction  with the  respective  audited financial
statements of  KCPL  and UCU  incorporated  by  reference in  this  Joint  Proxy
Statement/Prospectus   and   the   "UNAUDITED  PRO   FORMA   COMBINED  FINANCIAL
INFORMATION." See  "INCORPORATION OF  CERTAIN DOCUMENTS  BY REFERENCE"  in  this
Joint Proxy Statement/Prospectus.

                          MEETINGS, VOTING AND PROXIES
 
    This  Joint Proxy Statement/Prospectus is being furnished to (i) the holders
of KCPL Common Stock in connection with the solicitation of proxies by the  KCPL
Board from the holders of KCPL Common Stock for use at the KCPL Meeting and (ii)
the  holders of UCU Common Stock in  connection with the solicitation of proxies
by the  UCU Board  from the  holders of  UCU Common  Stock for  use at  the  UCU
Meeting. KCPL after the Mergers is referred to herein as "Maxim" and KCPL Common
Stock  after the  Mergers is  referred to herein  as "Maxim  Common Stock." This
Joint Proxy Statement/ Prospectus is also being furnished to the holders of  UCU
Common  Stock in connection with  the issuance of the  Maxim Common Stock in the
UCU Merger.
 
THE KCPL MEETING
 
    PURPOSE OF KCPL MEETING.  The purpose of the KCPL Meeting is to consider and
vote upon: (i)  a proposal to  approve the  Share Issuance pursuant  to which  a
maximum  of up to 54,000,000 shares of Maxim  Common Stock will be issued in the
UCU Merger, (ii) a proposal to approve the Maxim Stock Incentive Plan and  (iii)
a proposal to approve the Maxim MIC Plan.
 
    The  KCPL Board, by  a unanimous vote,  has adopted and  approved the Merger
Agreement, the Mergers and the transactions contemplated thereby, authorized the
execution and  delivery  of  the  Merger Agreement,  and  recommends  that  KCPL
shareholders  vote FOR approval of the Share Issuance, FOR approval of the Maxim
Stock Incentive Plan and FOR approval of the Maxim MIC Plan.
 
    In considering the  recommendation of  the KCPL  Board with  respect to  the
Share  Issuance and the  Maxim Plans, shareholders should  be aware that certain
members of KCPL's management  and the KCPL Board  have certain interests in  the
Mergers that are in addition to the interests of shareholders of KCPL generally.
See "THE MERGERS -- Conflicts of Interest."
 
    Pursuant  to  the  Merger  Agreement, the  consummation  of  the  Mergers is
conditioned upon approval  of proposal (i)  above, but is  not conditioned  upon
approval  by the  shareholders of KCPL  of the  Maxim Plans. If  approved by the
shareholders, the  Maxim Plans  will  be implemented  only if  the  transactions
contemplated by the Merger Agreement are consummated.
 
    Under  the  MGBCL, no  separate  vote of  KCPL  shareholders is  required to
approve the Mergers. However, as it is a condition to the closing of the Mergers
that KCPL shareholders approve the Share Issuance, a vote for the Share Issuance
is, in essence, a vote for the Mergers.
 
    DATE, PLACE  AND TIME;  RECORD DATE;  VOTING RIGHTS.   The  KCPL Meeting  is
scheduled  to be held at                    ,  on                   , August   ,
1996, commencing at         , local  time. Holders of record  of shares of  KCPL
Common  Stock at the close  of business on June 26,  1996, the KCPL Record Date,
will be entitled  to notice and  to vote at  the KCPL Meeting.  At the close  of
business  on the KCPL  Record Date, 61,902,083  shares of KCPL  Common Stock are
anticipated to be issued and outstanding and entitled to vote. Each  outstanding
share of KCPL Common Stock is entitled to one vote upon each matter presented at
the KCPL Meeting.
 
    A  majority  of  the voting  power  of  the shares  issued,  outstanding and
entitled to vote, present in person or  by proxy, shall constitute a quorum  for
the  transaction of business at  the KCPL Meeting. Under  the rules of the NYSE,
the affirmative vote of the holders of  a majority of the shares of KCPL  Common
Stock  voting  on  the Share  Issuance  where  the total  number  of  votes cast
represents over  50 percent  of  all outstanding  shares  of KCPL  Common  Stock
outstanding  on the KCPL Record Date is  required to approve the Share Issuance.
Abstentions will have the same effect as votes cast against such proposals,  but
broker  non-votes, if any,  will be disregarded  and will have  no effect on the
vote. Approval  of the  Share Issuance  is a  condition to  consummation of  the
Mergers.
 
    The  affirmative  vote of  a majority  of  the shares  of KCPL  Common Stock
present and entitled to  vote is required to  approve the Maxim Stock  Incentive
Plan and the Maxim MIC Plan. Abstentions will have the same effect as votes cast
against  such proposals, but broker non-votes  will be disregarded and will have
no effect on the vote.
 
                                       30
<PAGE>
    As of  the  KCPL Record  Date,  it is  anticipated  that the  directors  and
executive  officers of  KCPL, together  with their  affiliates as  a group, will
beneficially own  less than  1% of  the issued  and outstanding  shares of  KCPL
Common Stock.
 
   
    Direct  KCPL shareholder approval of the Mergers is not required under state
law for  the  following  reasons.  The UCU  Merger  is  between  a  wholly-owned
subsidiary of KCPL and UCU, both Delaware corporations. Under Section 251 of the
DGCL,  only stockholders of the corporations which are parties to the merger are
required to vote.  Because KCPL is  not a party  to the UCU  Merger, no vote  of
KCPL's  shareholders is  required under Delaware  law. Further,  no provision of
Missouri law requires that KCPL shareholders vote to approve the UCU Merger. The
Consolidating Merger  contemplated by  the Merger  Agreement is  a  "short-form"
merger  between KCPL and UCU  which will be KCPL's  wholly-owned subsidiary as a
result of the  UCU Merger. Missouri  law permits a  corporation owning at  least
ninety  percent of  the outstanding stock  of another corporation  to complete a
merger of such corporations without  any shareholder vote. In currently  pending
litigation, Western Resources, Robert L. Rives and an intervening shareholder of
KCPL  contend that the  Merger Agreement requires approval  of two-thirds of all
outstanding KCPL shares. See "THE MERGERS -- Certain Litigation."
    
 
    PROXIES.  Holders of the KCPL Common  Stock may vote either in person or  by
properly executed proxy. By returning a properly executed form of WHITE proxy, a
KCPL  shareholder authorizes the persons named therein  to vote all of such KCPL
shareholder's shares  on  behalf of  such  shareholder. Issued  and  outstanding
shares  of KCPL Common Stock which are represented by properly executed proxies,
will, unless such  proxies have been  revoked, be voted  in accordance with  the
instructions  indicated in such proxies. If  no instructions are indicated, such
shares will be voted  FOR approval of  the Share Issuance,  FOR approval of  the
Maxim  Stock  Incentive Plan  and FOR  approval of  the Maxim  MIC Plan.  A KCPL
shareholder may  revoke  a proxy  at  any time  prior  to the  KCPL  Meeting  by
delivering  to the Secretary of  KCPL a notice of  revocation or a duly executed
proxy bearing  a later  date or  by attending  the KCPL  Meeting and  voting  in
person.  Attendance at the KCPL Meeting will not in itself constitute revocation
of a proxy.
 
    KCPL will bear the cost of  soliciting proxies for the KCPL Meeting,  except
that  KCPL  and UCU  will  share equally  expenses  incurred in  connection with
printing and filing this Joint  Proxy Statement/Prospectus and the  Registration
Statement.  See "THE  MERGER AGREEMENT --  Expenses." In  addition to soliciting
proxies by mail, directors,  officers and employees  of KCPL, without  receiving
additional compensation therefor, may solicit proxies by telephone, by telecopy,
by telegram, in person or otherwise. KCPL has retained D.F. King & Co., Inc., 77
Water  Street,  New York,  New York  10008. The  fee for  such services  will be
between $200,000 and  $400,000 plus reimbursement  for reasonable  out-of-pocket
expenses.  In addition  to the  foregoing, UCU  and its  directors, officers and
employees, without  receiving  additional  compensation  therefor,  may  solicit
proxies  from  holders  of  KCPL  Common  Stock  by  mail,  telephone, telecopy,
telegram, in person or otherwise.
 
    The KCPL  Meeting may  be adjourned  to another  date and/or  place for  any
proper  purpose (including,  without limitation,  for the  purpose of soliciting
additional proxies).
 
THE UCU MEETING
 
    PURPOSE OF THE UCU MEETING.  The  purpose of the UCU Meeting is to  consider
and vote upon a proposal to approve the Merger Agreement and the UCU Merger.
 
    The  UCU  Board, by  unanimous  vote, has  adopted  and approved  the Merger
Agreement, authorized the execution  and delivery of  the Merger Agreement,  and
recommends  that UCU stockholders vote FOR  approval of the Merger Agreement and
the UCU Merger.
 
    In considering the recommendation of the  UCU Board with respect to the  UCU

    Each outstanding share of UCU Common Stock is entitled to one vote upon  the
Merger Agreement and the UCU Merger.
 
    PROXIES.   Holders of the  UCU Common Stock may vote  either in person or by
properly executed proxy. By returning a  properly executed form of WHITE  proxy,
the  UCU stockholder authorizes  the persons named  therein to vote  all the UCU
stockholder's shares on his  or her behalf. All  completed UCU proxies  returned
will  be voted in accordance with the instructions indicated on such proxies. If
no instructions are given,  the UCU proxies  will be voted  FOR approval of  the
Merger  Agreement and the  UCU Merger. A UCU  proxy may be  revoked by voting in
person at the UCU Meeting, by written notice to UCU's Corporate Secretary or  by
delivery  of a later-dated proxy, in each case prior to the closing of the polls
for voting at the UCU Meeting. Attendance at the UCU Meeting will not in  itself
constitute revocation of a proxy.
 
    UCU  will bear the cost of the  solicitation of proxies for the UCU Meeting,
except that KCPL and UCU will share equally expenses incurred in connection with
printing and  filing  this Joint  Proxy  Statement/Prospectus. See  "THE  MERGER
AGREEMENT  -- Expenses." Proxies may be solicited by certain directors, officers
and employees of  UCU or its  subsidiaries by mail,  by telephone, by  telecopy,
personally  or by  other communications,  without compensation  apart from their
normal salaries. UCU has retained Morrow & Co. to assist in the solicitation  of
proxies  from UCU stockholders,  including brokers' accounts, at  a fee for such
services of $50,000 plus reasonable  out-of-pocket expenses. In addition to  the
foregoing,  KCPL and  its directors,  officers and  employees, without receiving
additional compensation therefor, may solicit proxies from holders of UCU Common
Stock by mail, telephone, telecopy, telegram, in person or otherwise.
 
    The UCU Meeting may be adjourned to another date and/or place for any proper
purpose (including, without limitation, for the purpose of soliciting additional
proxies).
 
    As of  the  UCU  Record Date,  it  is  anticipated that  the  directors  and
executive officers of UCU, together with their affiliates, will beneficially own
2.2% of the issued and outstanding shares of UCU Common Stock.
 
                                  THE MERGERS
BACKGROUND OF THE MERGERS
 
    KCPL  and UCU share the view that the  energy industry has entered an era of
inevitable, accelerating  change that  will  have a  significant impact  on  the
future  competitive position of utility based energy companies and their ability
to maintain  and  increase earnings.  More  than  ever, the  industry  is  being
transformed  by  technological  advances, consumer  demand  and  legislative and
regulatory  reforms  which  are  leading  to  greater  competition  in  a   once
monopolistic industry.
 
                                       32
<PAGE>
    Both  KCPL and  UCU believe  that these  changes are  leading to fundamental
changes in the nature of energy related businesses. As a result, public  utility
companies  face increased  business risks  and limits  to their  ability to grow
earnings through  rate  base  increases and  are,  therefore,  pursuing  various
business  combinations  in  order to  reduce  risk  and create  new  avenues and
opportunities for earnings growth.  Accordingly, public utilities have  invested
and,  KCPL and UCU believe, will  continue to invest in non-regulated businesses
within the energy sector  and in businesses  complementary to their  traditional
business.  In response to intensified  competition, public utilities have sought
and, KCPL  and  UCU believe,  will  continue  to seek  opportunities  to  create
efficiencies  and control future costs through consolidation. Efficiency and the
ability to respond quickly to the needs of the market will be rewarded. KCPL and
UCU each share the view that  only efficient, low-cost suppliers of energy  that
pursue  reforms in the regulatory and legislative arenas will be able to compete
successfully in a changing marketplace.
 
    Recognizing this trend, KCPL and UCU each have separately studied  strategic
options and opportunities and have from time to time over the last several years
participated  in preliminary discussions with other utility and energy companies
regarding possible strategic  business combinations. In  October 1993, KCPL  and
UCU  executives  and  their  respective advisors  participated  in  a  number of
meetings regarding a business combination involving the two companies. After  an
exchange  and review of confidential data,  the two companies mutually agreed to
cease consideration of a business combination at that time.
 
    In June  1994,  KCPL  and  Western  Resources  also  exchanged  confidential
information  in  connection with  preliminary  discussions regarding  a possible
business combination. Upon  review of such  confidential information, in  August
1994,  KCPL advised Western Resources that KCPL was not interested in pursuing a
business  combination  with  Western   Resources.  Although  Western   Resources
indicated  a continuing  interest in pursuing  a business  combination with KCPL
from late 1994  through early  1996, KCPL  reaffirmed to  Western Resources  the
conclusion  of its analysis that a combination with Western Resources was not in
the best interest of KCPL's shareholders.
 
    On May 25, 1995 and again on June 6, 1995, A. Drue Jennings, Chairman of the
Board, President and  Chief Executive Officer  of KCPL, Richard  C. Green,  Jr.,
Chairman  of the  Board, President  and Chief  Executive Officer  of UCU,  and a
representative of DLJ, financial advisor to UCU, met to discuss a new  potential
joint   venture  between  the  two  companies  involving  power  operations  and
maintenance. Further discussions  were held by  senior operations executives  of
KCPL and UCU on June 10, 1995.
 
    KCPL and UCU subsequently each formed teams, which met throughout the summer
of  1995,  to  explore  new  joint  alliances  in  areas  including  operations,
information technology, marketing and procurement. Pursuant to a confidentiality
agreement, dated September  1, 1995,  the two  companies exchanged  confidential
information  in order to facilitate  such discussions and related investigations
of each other's business operations in connection therewith.
 
    The KCPL and  UCU teams  continued to  meet through  September, October  and
November  of  1995 and  periodically  updated their  respective  Chief Executive
Officers regarding  their  progress  in  exploring  additional  potential  joint
ventures  and strategic alliances. The meetings  between the respective teams of
the two companies as well  as discussions between the  members of the teams  and
their  respective Chief Executive  Officers revealed that  the two companies had
similar visions and  strategic outlooks in  a number  of areas. As  a result  of
these  meetings, both  companies continued to  discuss the  possibility of joint
ventures.
 
    Because of their shared views regarding the accelerating pace of the changes
facing the energy industry and, in  particular, the convergence of electric  and
gas  supplies into a single energy source giving customers the ability to choose
between the two, as well as the unique advantages a combined company would  have
to expand into additional opportunities in the unregulated sector and additional
acquisition  opportunities, on  October 30, 1995,  A. Drue  Jennings, Richard C.
Green, Jr., Turner  White, KCPL Senior  Vice President of  Retail Services,  and
Michael D. Bruhn, UCU Vice President of
 
                                       33
<PAGE>
Corporate  Development, met to discuss the general terms of a possible merger of
equals transaction. The parties recognized that unique opportunities for  growth
and  certain  synergies  would  be  available in  a  combined  company  and that
additional discussions and due  diligence were warranted.  At the conclusion  of
the  meeting, each Chief Executive Officer agreed to discuss with his respective
Board of Directors at their  upcoming regularly scheduled meetings, the  concept
of such a combination.
 
    The  KCPL Board met on November 7,  1995 and agreed that Mr. Jennings should
continue exploratory  discussions  with  UCU. Thereafter,  KCPL  consulted  with
Skadden  Arps, a law firm that had previously been engaged by KCPL in connection
with other matters, and on November 14, 1995, KCPL engaged Merrill Lynch as  its
financial  advisor  to  advise  KCPL with  respect  to  a  potential transaction
involving KCPL and UCU.
 
    The UCU Board met on November 9, 1995 and also agreed that Mr. Green  should
continue  preliminary discussions with KCPL. In  addition to its regular outside
legal counsel of Blackwell Sanders, UCU engaged the law firm of Weil, Gotshal  &
Manges  LLP ("Weil Gotshal") and  also retained DLJ as  its financial adviser to
advise with respect to the potential transaction involving KCPL and UCU.
 
    On November 10,  1995, Messrs.  Jennings, Green,  White and  Bruhn met  with
representatives  of  Skadden  Arps  and  Weil  Gotshal  to  conduct  preliminary
discussions regarding  a  merger  of  equals involving  the  two  companies.  On
November  18, 1995, the  Strategic Planning Committee  of the KCPL  Board met to
discuss the merits of such a business combination between KCPL and UCU in  light
of KCPL's long-term strategic plans. The committee concluded that the discussion
and analysis should continue.
 
    A  meeting  of  representatives  of  both  companies  and  their  respective
financial advisors was held on November 22, 1995 to discuss business,  financial
and  other  issues.  At  that  meeting,  the  companies  determined  that unique
opportunities were  present  in  the  proposed  business  combination  and  that
additional discussions and due diligence should proceed.
 
    A  meeting of representatives  of both companies  and their respective legal
and financial advisors was  also held on  November 28, 1995  to commence a  more
detailed   examination  of   the  numerous   structural,  corporate  governance,
regulatory and  other issues  relating  to the  proposed transaction.  Also,  on
November  28,  1995,  KCPL  and UCU  entered  into  a  confidentiality agreement
pursuant to which the companies and their representatives provided  confidential
information  to each other  in connection with  the proposed transaction. Senior
management of  both companies  analyzed financial,  operational, regulatory  and
other legal issues relating to such a possible business combination.
 
    During  December 1995, the chief  executive officers of KCPL  and UCU met on
several occasions  to  discuss key  issues  relating to  the  possible  business
combination.  On December 6, 1995, Ernst & Young was retained by KCPL and UCU to
identify and quantify the potential cost savings from synergies available from a
merger of KCPL and UCU.
 
    Through mid-January  1996,  representatives  of both  KCPL  and  UCU,  their
counsels  and financial  advisors held numerous  meetings and  participated in a
number of conference calls  to conduct due diligence  and discuss and  negotiate
the terms of a possible business combination pursuant to which the businesses of
KCPL and UCU would be merged. These ongoing discussions focused on the structure
of  the transaction, the conditions to  the transaction, the covenants regarding
the operations of each company during the period between signing of an agreement
and consummation of  the transactions contemplated  thereby, regulatory  matters
impacting the combination and possible termination fees.
 
    At  a  meeting  of  the  KCPL  Board  on  December  8,  1995,  Merrill Lynch
representatives reviewed for the KCPL Board preliminary financial data regarding
the two companies. Skadden Arps attorneys  also described to the KCPL Board  its
legal  responsibilities and fiduciary  duties to shareholders  in evaluating the
proposed transaction. The KCPL  Board discussed the  rationale for the  proposed
transaction and authorized management to continue its analysis and discussion.
 
                                       34
<PAGE>
    At a meeting of the UCU Board on December 9, 1995, DLJ's representatives and
officers  of UCU described the status of  the proposed transaction with KCPL and
analyzed preliminary  financial data.  The UCU  Board authorized  the  executive
officers of UCU to continue discussions with representatives of KCPL.
 
    At  a meeting  of the  KCPL Board  on January  5, 1996,  the KCPL  Board was
updated  regarding  the  proposed  business  combination,  including   potential
strategic  benefits of  the transaction  and the  status of  negotiations. These
potential strategic benefits included the ability of a stronger combined company
to operate in a dynamic environment; enhanced opportunities for earnings  growth
that  would create value for shareholders; diversification and, hence, reduction
of regulatory risks that would result  from the combination; and production  and
operation  cost  savings.  Merrill  Lynch  representatives  presented  a general
overview of  the various  UCU businesses  and the  methodologies that  might  be
relevant  to a  financial analysis of  a business combination,  and Skadden Arps
attorneys provided advice  regarding relevant regulatory  issues, explained  the
mechanics of the proposed transaction and outlined the terms of the then current
draft of the Original Merger Agreement. Pursuant to such agreement, KCPL and UCU
would  each  merge with  and  into KCU,  with KCU  surviving  in each  case (the
"Original Merger") and stockholders  of KCPL and UCU  would each receive  common
stock  of KCU ("KCU Common  Stock") in exchange for  their shares of KCPL Common
Stock and UCU Common Stock,  respectively. The KCPL Board concluded  unanimously
that  management  and  its advisors  should  continue to  pursue,  negotiate and
evaluate the proposed combination.
 
    At a meeting of the UCU Board on January 12, 1996, the UCU Board was updated
on the merger discussions.
 
    During their discussion  regarding the  parties' synergies  analysis at  the
January  5, 1996 meeting of  the KCPL Board and the  January 19, 1996 meeting of
the UCU Board, Ernst & Young emphasized  that the estimated net cost savings  of
approximately  $619  million  over  a  10-year period  were  all  created  by or
attributable to the proposed merger and  did not include other types of  savings
that  might  be achieved  without a  merger.  Ernst &  Young explained  that the
projected cost  savings  reflected  the  creation of  cost  reductions  or  cost
avoidance  opportunities through the ability to consolidate separate stand-alone
operations  into  a  single  entity.   This  consolidation  would  thus   enable
duplicative   functions  and  positions  to  be  eliminated,  similar  corporate
activities to be combined,  avoided or reduced in  scope, external purchases  of
goods  and services  to be aggregated,  technical skills and  capabilities to be
optimized and  shared and  capital expenditures  to be  avoided. Ernst  &  Young
informed  the KCPL Board and  the UCU Board that  the report was preliminary and
that while components of the analysis might change, the joint synergies analysis
had indicated estimated savings opportunities in the regulated utility  business
totalling  approximately $619  million net of  all anticipated  costs to achieve
those savings  and costs  expected to  be incurred  to consummate  the  proposed
merger.  The approximately  $619 million  of net  cost savings  were composed of
approximately $232 million  in labor  related cost  savings, approximately  $128
million  of avoidable capital requirements  and reductions of approximately $259
million in other non-capital related  expenses. The cost savings estimates  were
developed  and quantified by the parties based on the individual facts regarding
existing and planned costs  for each company, the  current mode of operation  of
each  company, the potential organization and operational framework post-merger,
the estimated timing to achieve the  savings and the interrelationship of  these
factors  and the costs and complexity of savings attainment. See "THE MERGERS --
Synergies from  the  Mergers,"  "-- Additional  Operational  Benefits"  and  "--
Enhancement of Financial Performance."
 
    During  the week of January 15, 1996, the financial advisors of KCPL and UCU
discussed the methodology  for determining the  appropriate exchange ratios  for
the Original Merger and negotiated with respect thereto, and late in the evening
on  January 18, 1996, together  with senior officers of  KCPL and UCU, agreed to
recommend to each company's  Board of Directors that  each share of KCPL  Common
Stock would be converted into the right to receive 1.0 share of KCU Common Stock
and  each share of UCU Common Stock would be converted into the right to receive
1.096 shares of KCU Common Stock.
 
                                       35
<PAGE>
    Meetings of the KCPL Board and the  UCU Board were held on January 19,  1996
to  consider and  approve the  Original Merger.  At each  company's meeting, its
senior management and financial and legal advisors discussed material aspects of
the Original Merger and related transactions. At the KCPL Board meeting, Merrill
Lynch representatives reviewed for  the KCPL Board  various financial and  other
information  and delivered its oral opinion to the KCPL Board, which opinion was
subsequently confirmed in a written opinion dated as of January 19, 1996,  that,
as  of such date and based upon the assumptions made, matters considered and the
limits of review as set forth in  such opinion, the exchange ratio of 1.0  share
of  KCU Common  Stock for each  share of  KCPL Common Stock  (the "Original KCPL
Exchange Ratio") was fair to  the holders of KCPL  Common Stock (other than  UCU
and  its  affiliates) from  a financial  point of  view. Skadden  Arps attorneys
summarized recently negotiated terms of  the Original Merger Agreement  relating
to  employee benefit issues and the proposed organizational documents of KCU. In
addition, the KCPL Board  was advised as to  the reasonableness of the  proposed
employment  agreements to be entered into at  the Effective Time by KCU and each
of Messrs. Jennings and  Green based on a  review of similar agreements  entered
into  in connection with similar transactions  in the electric utility industry.
After considering and discussing the  various presentations at such meeting  and
at  prior meetings as well as the  recommendation of KCPL's management, the KCPL
Board approved, by  a unanimous vote  of those directors  present, the  Original
Merger  Agreement, the Original Merger and the transactions contemplated thereby
and authorized the execution of the Original Merger Agreement.
 
    At a  meeting of  the UCU  Board  on January  19, 1996,  the UCU  Board  was
presented  with a  discussion of  the status of  the negotiations  with KCPL and
various details relating to the proposed Original Merger. Representatives of DLJ
reviewed for the UCU Board various financial and other information and delivered
oral and written opinions that  as of such date  and subject to the  assumptions
made,  matters considered and limits  of the review undertaken,  as set forth in
such opinions and assuming the Original KCPL Exchange Ratio, the exchange  ratio
of  1.096 shares  of KCU Common  Stock for each  share of UCU  Common Stock (the
"Original UCU Exchange  Ratio") was  fair, from a  financial point  of view,  to
holders  of UCU  Common Stock. Representatives  from Blackwell  Sanders and Weil
Gotshal outlined the terms  of the Original Merger  Agreement for the UCU  Board
and  advised as to the fiduciary duties  of the directors. After considering and
discussing the various  presentations, the  UCU Board approved,  by a  unanimous
vote,  the Original Merger  Agreement, the Original  Merger and the transactions
contemplated thereby  and  authorized  the  execution  of  the  Original  Merger
Agreement.
 
    The Original Merger Agreement and certain related documents were executed on
January 19, 1996 following such approval by the KCPL Board and the UCU Board.
 
    On  April 9, 1996, a  joint proxy statement/prospectus of  KCPL, UCU and KCU
relating to the  Original Merger  was mailed to  stockholders of  KCPL and  UCU.
Included  in  such  joint  proxy  statement/prospectus  were  notices  of annual
meetings of stockholders of KCPL and UCU,  as the case may be, establishing  May
22, 1996 as the date on which both KCPL and UCU would have their annual meetings
to  consider and vote upon, among other  things, the Original Merger and related
matters, the election of directors and the ratification of independent auditors.
 
    On April 14, 1996, Mr. Jennings received  a telephone call from Mr. John  E.
Hayes,  Jr.,  Chairman  of the  Board  and  Chief Executive  Officer  of Western
Resources, in which Mr.  Hayes informed Mr. Jennings  that he was delivering  to
Mr. Jennings an unsolicited proposal to the KCPL Board pursuant to which Western
Resources would acquire all of the outstanding KCPL Common Stock in exchange for
shares  of  common  stock,  par  value $5.00  per  share,  of  Western Resources
("Western Resources Common  Stock") valued at  $28.00 per share  of KCPL  Common
Stock, subject to adjustment.
 
                                       36
<PAGE>
    Following  such  telephone conversation,  on  April 14,  1996,  Mr. Jennings
received from Western Resources a letter  (the "April 14 Letter") setting  forth
Western Resources' unsolicited merger proposal. In the letter, Western Resources
proposed  that KCPL and Western  Resources merge in a  transaction in which each
holder of KCPL  Common Stock  would receive  $28.00 worth  of Western  Resources
Common  Stock, subject  to a "collar"  limiting the amount  of Western Resources
Common Stock that holders  of KCPL Common  Stock would receive  to no more  than
0.985 shares and no less than 0.833 shares of Western Resources Common Stock for
each  share of KCPL Common Stock. Shortly after delivery of the April 14 Letter,
Western Resources publicly announced its unsolicited merger proposal.
 
    On April 15,  1996, Western Resources  filed an application  with the  State
Corporation  Commission  of  the State  of  Kansas seeking  approval  of Western
Resources' proposed business combination with  KCPL and a Petition to  Intervene
in the Original Merger.
 
    A  meeting of the  KCPL Board was held  on April 19,  1996 and reconvened on
April 21, 1996  to consider Western  Resources' proposal. At  this meeting,  the
KCPL  Board received  presentations concerning Western  Resources' proposal from
KCPL's management and  its financial  and legal  advisors. Representatives  from
Skadden  Arps advised the  KCPL Board with  respect to certain  legal matters in
connection   with   its   consideration   of   Western   Resources'    proposal.
Representatives  from Ernst  & Young provided  information to the  KCPL Board in
three areas.  First, Ernst  & Young  provided a  summary of  the differences  in
assumptions  included in  the Ernst &  Young synergies report  and the synergies
study conducted for  Western Resources  by Deloitte  & Touche  LLP ("Deloitte  &
Touche").  Second, Ernst  & Young identified  the following  areas where Western
Resources and Deloitte &  Touche appeared to  have made inaccurate  assumptions:
(i)  that  KCPL employed  more persons  than  they actually  do; (ii)  that KCPL
budgeted more for  customer information  systems than KCPL  actually has;  (iii)
that  the costs of operating  KCPL's data center were  higher than they actually
are; and (iv) that KCPL's level of benefits loading was higher than it  actually
was.  Finally, Ernst & Young noted for the KCPL Board the fact that the group of
comparable companies reviewed to develop benchmarks demonstrated wide  variances
in  projected synergies thereby bringing into question whether an average of the
group's  projected  synergies  provided  an  appropriate  benchmark  from  which
conclusions could be drawn.
 
   
    On  April 19,  1996, Merrill  Lynch made  a presentation  to the  KCPL Board
summarizing Western Resources' business and its proposal contained in the  April
14   Letter.  The  purpose  of  Merrill  Lynch's  presentation  was  to  provide
information to the KCPL Board regarding Western Resources and its proposal,  and
accordingly,  Merrill Lynch drew no  conclusions from its presentation regarding
such proposal. The following is a summary of such presentation.
    
 
    Merrill Lynch  summarized  the key  financial  terms of  Western  Resources'
proposal  contained in  the April 14  Letter, including the  announced price per
share of KCPL Common Stock, the operation of the proposed "collar" over a  range
of  prices  of  the  Western Resources  Common  Stock,  the  proposed accounting
treatment, the synergies claimed by Western Resources, the proposed  composition
of the board of directors of the combined company, the pro forma share ownership
of  the combined company, and the implied 1996 annual dividend rate per share of
the KCPL Common Stock.
 
   
    Using publicly available information, Merrill  Lynch presented a profile  of
Western  Resources,  including  a  description of  Western  Resources'  lines of
business, a summary of recent financial  and operating results, a chronology  of
significant  recent  corporate  events,  and a  comparison  of  the  stock price
performance of the Western Resources Common Stock to the stock price performance
of the KCPL Common Stock,  the UCU Common Stock  and the S&P Electric  Companies
Index for the three year and twelve month periods preceding the April 14 Letter.
Merrill  Lynch  also presented  excerpts  from recent  commentaries  by research
analysts  regarding  Western  Resources,  a  comparison  of  research  analysts'
earnings  estimates for Western Resources  complied by First Call, Institutional
Brokers Estimating  Service  and  Nelsons, respectively,  and  a  comparison  of
certain financial and
    
 
                                       37
<PAGE>
operating  information and ratios  for Western Resources  with the corresponding
financial and operating information  and ratios for a  group of publicly  traded
companies  that  Merrill  Lynch  deemed  to  be  reasonably  similar  to Western
Resources.
 
    Using publicly available research  analysts' earnings estimates for  Western
Resources  and KCPL, Merrill Lynch reviewed  certain pro forma effects resulting
from Western  Resources'  proposal, including  the  potential impact  to  KCPL's
projected  stand-alone  earnings per  share,  dividends per  share  and dividend
payout ratios,  both  including  and  excluding  synergies  claimed  by  Western
Resources.  In  addition,  Merrill  Lynch  reviewed  certain  pro  forma effects
resulting from Western Resources'  proposal and the  potential impact to  KCPL's
projected  stand-alone earnings per share and dividend payout ratios, assuming a
range of  synergies claimed  by  Western Resources  that  would be  retained  by
shareholders,  a range of potential  rate reductions affecting Western Resources
on a stand-alone basis, and a range of aggregate synergies.
 
    Using  publicly  available  information,  Merrill  Lynch  reviewed   certain
financial  information  and  ratios  claimed or  implied  by  Western Resources'
proposal and  compared  such  information  and  ratios  with  the  corresponding
financial  information and ratios for a number of recent combinations of utility
companies, including the terms of the Original Merger with UCU.
 
   
    On April 21, the KCPL Board, based upon the presentations given, the  advice
received  and the  considerations discussed at  such meeting of  the KCPL Board,
determined that further exploration of the Western Resources proposal was not in
the best interests of KCPL, its  shareholders, its employees and its  customers.
Also on such date, the KCPL Board reaffirmed its approval of the Original Merger
with UCU.
    
 
    On April 22, 1996, Mr. Jennings delivered to Mr. Hayes a letter stating that
the  KCPL  Board had  rejected Western  Resources'  proposal. Mr.  Jennings also
telephoned Mr. Hayes to inform him of the decision of the KCPL Board.
 
    On April 22, 1996, Western Resources announced that it intended to  commence
an unsolicited exchange offer, and that it had filed preliminary proxy materials
for use in soliciting proxies from holders of KCPL Common Stock in opposition to
the  approval and adoption of the Original Merger, the Original Merger Agreement
and the transactions contemplated  thereby. On the  same day, Western  Resources
filed  a Registration Statement  on Form S-4 (the  "Western Resources Form S-4")
with the SEC  which described  a proposed  offer to  exchange Western  Resources
Common Stock for all of the outstanding shares of KCPL Common Stock. Pursuant to
a  preliminary  prospectus  included  in the  Western  Resources  Form  S-4 (the
"Western Resources  Preliminary  Prospectus"),  Western  Resources  proposed  to
offer,  upon the terms  and subject to  the conditions set  forth in the Western
Resources  Preliminary  Prospectus  and  in  a  related  Letter  of  Transmittal
(together, the "Proposed Western Resources Offer"), to exchange less than a full
share  of  Western Resources  Common Stock  for each  outstanding share  of KCPL
Common Stock validly tendered on or  prior to the "Expiration Date" (as  defined
in  the  Western  Resources  Preliminary  Prospectus)  of  the  Proposed Western
Resources Offer and  not properly withdrawn.  As initially filed  with the  SEC,
each  such share would be  entitled to receive a fraction  of a share of Western
Resources Common Stock equal to the "Western Resources Exchange Ratio,"  defined
as 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 the Western Resources Common
Stock (as  reported  on 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 Western Resources Exchange  Ratio would not be  less than 0.833 nor  greater
than 0.985.
 
    According to the Western Resources Preliminary Prospectus, Western Resources
intends,  as  soon as  practicable after  consummation  of the  Proposed Western
Resources Offer,  to  seek  to merge  KCPL  with  and into  itself  pursuant  to
applicable law (the "Proposed Western Resources Merger").
 
    The  Proposed Western Resources Offer is subject to numerous conditions. The
Proposed Western Resources Offer  is conditioned upon,  among other things,  (i)
there being validly tendered and not
 
                                       38
<PAGE>
withdrawn  prior to the Expiration Date a  number of shares of KCPL Common Stock
which will constitute at least ninety percent of the total number of outstanding
shares of KCPL Common Stock on a  fully diluted basis (as though all options  or
other  securities  convertible  into  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 Proposed Western Resources Offer,
(ii) approval  of the  issuance  of shares  of  Western Resources  Common  Stock
pursuant  to  the  Proposed Western  Resources  Offer and  the  Proposed Western
Resources Merger and approval of an amendment to the Western Resources  articles
of  incorporation to increase  the number of shares  of Western Resources Common
Stock authorized for issuance  by the holders,  voting as a  single class, of  a
majority  of the shares of Western  Resources Common Stock and Western Resources
preferred stock outstanding on  the applicable record date  and approval of  the
Proposed Western Resources Merger by the holders, voting as a single class, of a
majority of the Western Resources preferred stock, (iii) Western Resources being
satisfied, in its sole discretion, that the provisions of Section 351.407 of the
MGBCL are inapplicable to Western Resources and the transactions contemplated by
the  Proposed Western Resources Offer or full voting rights for all shares to be
acquired by Western Resources pursuant  to the Proposed Western Resources  Offer
having  been approved by the shareholders of KCPL pursuant to such statute, (iv)
Western Resources being satisfied, in  its sole discretion, that the  provisions
of  Section 351.459 of  the MGBCL will not  prohibit for any  period of time the
consummation of the  Proposed Western  Resources Merger or  any other  "Business
Combination"  (as defined in such statute)  involving KCPL and Western Resources
or any subsidiary of Western Resources, (v) the shareholders of KCPL not  having
approved  the Original Merger Agreement,  (vi) all regulatory approvals required
to consummate  the Proposed  Western Resources  Offer and  the Proposed  Western
Resources  Merger having been  obtained and remaining in  full force and effect,
all statutory waiting  periods in  respect thereof  having expired  and no  such
approval  containing any conditions or  restrictions which the Western Resources
board of directors reasonably determines in  good faith will have or  reasonably
could  be expected to have a material  adverse effect on Western Resources, KCPL
and their respective subsidiaries taken as a whole, (vii) the receipt by Western
Resources of a letter from its  independent public accountants stating that  the
Proposed  Western  Resources  Merger  will qualify  as  a  pooling  of interests
transaction under generally  accepted accounting principles  and applicable  SEC
regulations,  (viii) Western Resources being  satisfied, in its sole discretion,
that it will be able  to consummate the Proposed  Western Resources Merger as  a
"short-form"  merger pursuant to the provisions  of Section 351.447 of the MGBCL
and Section 17-6703  of the  Kansas General Corporation  Code immediately  after
consummation  of the Proposed  Western Resources Offer  and (ix) all outstanding
shares of KCPL Preferred Stock having been redeemed.
 
    On May  3, 1996,  Western  Resources commenced  soliciting proxies  of  KCPL
shareholders in opposition to the Original Merger.
 
    On  May 6, 1996, KCPL and UCU  announced that they would recommend an annual
dividend of  $1.85 per  common  share for  KCU. Also  on  May 6,  1996,  Western
Resources announced that it had increased the lower limit of the "collar" in the
Proposed  Western Resources Offer.  According to Western  Resources, the minimum
number of shares of Western Resources Common Stock that KCPL shareholders  would
receive  for each share of  KCPL Common Stock if  the Proposed Western Resources
Offer is consummated would be changed from 0.833 to 0.91. The maximum number was
not changed.
 
    On May 9,  1996, the KCPL  Board met in  order to review  the status of  the
Original  Merger and the Proposed Western  Resources Offer. At such meeting, the
KCPL Board received presentations  from its management  and financial and  legal
advisors  regarding recent developments and the financial and legal terms of the
Proposed Western  Resources Offer,  including  the May  6,  1996 change  in  the
"collar."  In  addition, representatives  from the  Palmer Bellevue  practice of
Coopers & Lybrand Consulting  ("CLC"), which had been  retained by KCPL  shortly
after  the announcement of  the Proposed Western  Resources Offer, were present.
CLC reviewed with the KCPL Board the synergies analysis undertaken on behalf  of
Western  Resources in connection with the Proposed Western Resources Offer. This
review was based on publicly available information. Their review concluded  that
the study conducted on behalf of Western Resources by Deloitte & Touche appeared
to  contain certain flaws which result  in overestimates of the savings expected
to  be  realized.  Such  flaws  identified  were:  (a)  the  application  of   a
 
                                       39
<PAGE>
discount on materials procurement that assumes similarities and commonalities in
plant  that do not exist; (b) the use  of a labor benefits loading of 34% rather
than the actual  KCPL benefits loading  which averages 26%;  (c) the  assumption
that  layoffs will not be required for  headcount reductions estimated to be 36%
greater in the proposed combination of KCPL and Western Resources than in  other
recent  utility mergers;  (d) the assumption  that 100%  of headcount reductions
will be available as  of January 1,  1998, a time  virtually at the  anticipated
time  of closing a business combination with  Western Resources; and (e) the use
of a  4.3%  labor  inflation  rate in  contrast  to  relatively  contemporaneous
Deloitte  & Touche utility synergy studies  which assumes a 3.5% labor inflation
rate. Additionally, they reviewed the study conducted by Ernst & Young  relative
to  likely savings  related to  synergies resulting  from the  proposed Original
Merger. They concluded that the study was conservative in its assumptions,  well
documented  and professional in  its methodology. There was  no report issued by
CLC related to these conclusions.
 
    During the period  beginning on May  10, 1996  and ending on  May 19,  1996,
various  meetings were  held between  executives of  KCPL and  UCU to  discuss a
possible change in the exchange ratios  in the Original Merger, certain  changes
in  the structure of the Original Merger and other possible changes to the terms
of the Original Merger. During the  course of such meetings, representatives  of
UCU  indicated that  UCU would  consider a change  in the  Original UCU Exchange
Ratio, but any such change would be  conditioned upon a change in the  structure
of  the transaction to  the form set forth  in the Merger  Agreement. On May 18,
1996, representatives of KCPL  and UCU agreed to  recommend to their  respective
Boards  of Directors the  Exchange Ratio of  one share of  KCPL Common Stock for
each share  of UCU  Common  Stock and  the structure  set  forth in  the  Merger
Agreement and described in this Joint Proxy Statement/Prospectus, subject to the
approvals of the KCPL Board and the UCU Board.
 
    On  May  19, 1996,  the UCU  Board met  to consider  and approve  the Merger
Agreement. At  such meeting,  UCU's senior  management and  financial and  legal
advisors  summarized the proposed merger.  Also at such meeting, representatives
of DLJ reviewed for  the UCU Board various  financial and other information  and
delivered  an oral opinion that  as of such date  and subject to the assumptions
made, matters considered and  limits of the review  undertaken, as set forth  in
such  opinion, the Exchange Ratio  was fair, from a  financial point of view, to
holders of UCU Common  Stock. UCU's legal advisors  noted that the structure  of
the  merger  had  been  modified  to  provide  for  the  merger  of  UCU  with a
wholly-owned subsidiary of KCPL following  which UCU stockholders would  receive
one  share of KCPL Common Stock for  each share of UCU Common Stock. Thereafter,
UCU would be merged into KCPL and the surviving corporation would be a  Missouri
corporation  to be renamed. It was noted  by the legal advisors that the revised
structure would require only  a majority vote of  KCPL's shareholders voting  at
the meeting, rather than two-thirds vote of the outstanding shares, and that the
vote required by UCU would remain the same. The legal advisors further discussed
with  the UCU Board  the differences between  Missouri and Delaware  law and the
articles of incorporation  and bylaws proposed  for Maxim as  compared to  those
contemplated  for  the surviving  corporation  pursuant to  the  Original Merger
Agreement. The UCU Board also discussed the fact that the change in the Original
UCU Exchange  Ratio  was conditioned  upon  a change  in  the structure  of  the
transaction to the form set forth in the Merger Agreement. After considering and
discussing the various presentations at such meeting, the UCU Board approved the
Merger  Agreement,  the UCU  Merger and  the transactions  contemplated thereby,
authorized the execution and  delivery of the Merger  Agreement and granted  the
Chairman  and  Chief  Executive  Officer  of UCU  the  authority  to  direct the
Secretary of UCU to remove from the agenda of the UCU annual meeting to be  held
on  May 22, 1996 the proposal to approve the Original Merger Agreement. See "THE
MERGERS -- Opinion of UCU's Financial Advisor" for a discussion of parts of  the
presentation made by DLJ to the UCU Board at such meeting.
 
    On  May 20,  1996, the  KCPL Board  met to  consider and  approve the Merger
Agreement. At such  meeting, KCPL's  senior management and  financial and  legal
advisors  discussed the material  aspects of the Mergers.  Also at such meeting,
Merrill Lynch representatives reviewed for the KCPL Board various financial  and
other  information  and delivered  its  oral opinion  to  the KCPL  Board, which
opinion was subsequently  confirmed in  a written opinion  dated as  of May  20,
1996,  that,  as of  such  date and  based  upon the  assumptions  made, matters
considered and limits of review as set forth in
 
                                       40
<PAGE>
such opinion, the Exchange Ratio  was fair to the  holders of KCPL Common  Stock
(other than UCU and its affiliates) from a financial point of view. Skadden Arps
attorneys  summarized and  discussed (i)  the revised  deal structure,  (ii) the
reduction in  the  percentage  of  KCPL shareholders  required  to  approve  the
transaction from two-thirds of the outstanding shares to a majority of a quorum,
(iii) the tax-free structure of the transaction, (iv) the removal of dissenters'
right  of appraisal and (v) the fact that Maxim would be a Missouri corporation.
See "THE MERGERS  -- Opinion of  KCPL's Financial Advisor"  for a discussion  of
parts  of  the presentation  made by  Merrill Lynch  to the  KCPL Board  at such
meeting. After  considering and  discussing the  various presentations  at  such
meeting  and  at  prior  meetings  as  well  as  the  recommendation  of  KCPL's
management, the KCPL Board  approved the Merger  Agreement and the  transactions
contemplated  thereby and  directed that the  proposals to  approve the Original
Merger Agreement and related transactions be removed from the agenda of the KCPL
annual meeting of shareholders to be held on May 22, 1996.
 
    The Merger Agreement and certain related documents were executed on May  20,
1996  following such approval by the KCPL Board  and the UCU Board, and KCPL and
UCU issued the following joint press release:
 
                         KCPL AND UTILICORP AMEND TERMS
                              OF MERGER AGREEMENT
                    MAY 22 VOTE ON PREVIOUS ACCORD CANCELLED
 
        KANSAS CITY, Missouri, May 20, 1996 -- Kansas City Power & Light Company
    (NYSE: KLT) and UtiliCorp United Inc. (NYSE: UCU) announced today that  they
    have  entered into  an Amended  and Restated  Agreement and  Plan of Merger.
    Under the  revised terms  of the  merger,  a new  KCPL subsidiary  would  be
    created,  and it  would be  merged into  UtiliCorp. UtiliCorp  would then be
    merged with KCPL  to form  the combined company.  Shareholders of  UtiliCorp
    would receive one share in the merged company for each UtiliCorp share held.
    KCPL  shareholders would continue to hold  their existing KCPL shares. Other
    substantive terms  of the  merger  will remain  the same.  Previously,  KCPL
    holders  would have received  one share of  stock in a  new company for each
    share held, while  UtiliCorp shareholders would  have received 1.096  shares
    for each share held.
 
        The  transaction is  anticipated to be  tax-free for  both UtiliCorp and
    KCPL shareholders and will be accounted  for as a pooling of interests.  The
    revised merger agreement was unanimously approved by the boards of directors
    of both companies.
 
        The merger of equals will create a diversified energy company with total
    assets  of approximately  $6.4 billion  and about  2.2 million  customers in
    domestic and international markets.
 
        The boards of KCPL and  UtiliCorp recommend that the initial  annualized
    dividend  rate upon completion of the merger be set at $1.85 per share. This
    compares to  UtiliCorp's current  dividend  of $1.76  per share  and  KCPL's
    current  divided of $1.56 per share.  Each company will continue its current
    dividend policy until completion of the merger.
 
        Drue Jennings, Chairman and Chief Executive Officer of KCPL, said, "This
    revised agreement preserves the  significant benefits of the  KCPL/UtiliCorp
    strategic   merger  for   shareholders  of   both  companies   and  provides
    shareholders with even greater value.  The merger combines the strengths  of
    both  companies  to form  a diversified  growth  company, fully  prepared to
    compete effectively in  the deregulated  utility industry. The  merger is  a
    friendly  combination  designed  to  distribute  benefits  equitably between
    shareholders and customers. We  are confident it  will receive all  required
    regulatory approvals."
 
        "As  we have  stated since our  first announcement, we  believe that our
    merger will create a truly unique company with a winning growth strategy for
    the future,"  said  Richard C.  Green,  Jr., Chairman  and  Chief  Executive
    Officer  of UtiliCorp United. "Both KCPL  and UtiliCorp want the opportunity
    to make that happen. Business is about choices. And, in order to  facilitate
    this  merger, we have chosen another tack to ensure the delivery of benefits
    and value to our key constituents."
 
                                       41
<PAGE>
        Upon completion of the transaction, the board of KCPL will consist of 18
    members: nine from KCPL and nine from UtiliCorp.
 
        KCPL and UtiliCorp shareholders will vote on the proposed transaction at
    separate special  meetings expected  to  be held  this summer.  The  Amended
    Merger Agreement requires an affirmative vote by owners of a majority of the
    outstanding  shares of UtiliCorp. The Agreement also calls for KCPL to issue
    new shares to complete the merger  which will require, under New York  Stock
    Exchange  rules, approval by owners of a  majority of the KCPL shares voting
    at a duly called meeting.
 
        The companies do not expect any interruption in the previously disclosed
    regulatory-approval process. The two  companies plan in  the near future  to
    file  revised proxy soliciting materials pertaining to the amended agreement
    with the Securities and Exchange Commission.
 
        As a  result  of  the  revised merger,  both  KCPL  and  UtiliCorp  have
    cancelled  the shareholder votes on the  original merger proposal which were
    scheduled to be held at each company's annual meeting on May 22, 1996.  Both
    annual meetings will still be held on May 22, 1996 in Kansas City to conduct
    all non-merger-related business on the agendas.
 
                                    *  *  *
 
    Also  on May 20,  1996, KCPL commenced  litigation against Western Resources
and others seeking certain declaratory  judgments in connection with the  Merger
Agreement   and  the   transactions  contemplated   thereby.  See   "--  Certain
Litigation."
 
    KCPL's and UCU's directors  were elected, and  the other matters  considered
were  approved, by  each company's  respective stockholders  at their respective
annual meetings on May 22, 1996.
 
    On June 17, 1996, Western Resources commenced a solicitation of proxies from
KCPL shareholders in opposition to the Share Issuance and announced that it  was
increasing  the  price in  its offer  to merge  with KCPL  to $31.00  of Western
Resources Common  Stock  for each  share  of KCPL  Common  Stock, subject  to  a
"collar"  pursuant to which each  share of KCPL Common  Stock would be exchanged
for no more than 1.1 and no  less than 0.933 shares of Western Resources  Common
Stock (the "June 17 Announcement").
 
    Also  on June 17,  1996, KCPL issued  a press release  stating that the KCPL
Board  will  review  Western  Resources'  proposal  in  due  course  and  advise
shareholders of developments as they occur.
 
    On  June  19, 1996,  Western  Resources amended  the  terms of  the Proposed
Western Resources  Offer to  reflect the  increase in  price and  change in  the
"collar" announced in the June 17 Announcement.
 
   
    A  meeting of the KCPL Board was held  on June 24, 1996 to consider the June
17 Announcement. Representatives from  Skadden Arps advised  the KCPL Board  and
answered  questions with respect to certain legal matters in connection with its
consideration  of  Western  Resources'  proposal   contained  in  the  June   17
Announcement.  In addition, the KCPL Board consulted with and asked questions of
KCPL's management, Merrill Lynch, and  KCPL's proxy solicitor regarding  Western
Resources' proposal contained in the June 17 Announcement.
    
 
   
    On June 24, 1996, the KCPL Board, based upon the considerations discussed at
the June 24, 1996 meeting of the KCPL Board, determined that further exploration
of  the proposal of Western Resources contained  in the June 17 Announcement was
not in  the best  interests of  KCPL, its  shareholders, its  employees and  its
customers.  The KCPL Board also  reaffirmed its approval of  the Mergers and the
Merger Agreement.

    On June 24, 1996, Mr. Jennings delivered to Mr. Hayes the following letter:
    
 
   
                                                                   June 24, 1996
    
 
   
      Mr. John E. Hayes, Jr.
       Chairman of the Board and
        Chief Executive Officer
       Western Resources, Inc.
       818 Kansas Avenue
       Topeka, Kansas 66612
    
 
   
       Dear John:
    
 
   
           The Board of  Directors (the "Board")  of Kansas City  Power &  Light
       Company ("KCPL") has carefully considered the revised proposal of Western
       Resources, Inc. ("Western") as set forth in your letter of June 17, 1996,
       and  has unanimously  voted to  reject Western's  unsolicited proposal to
       acquire KCPL. We  continue to  believe strongly  that Western  is not  an
       appropriate  strategic partner  for KCPL  and that  Western's unsolicited
       proposal is not in the best interests  of our shareholders, nor is it  in
       the  best interests of our  customers, employees and other constituencies
       served  by  KCPL,  and  we  reaffirm  our  commitment  to  our   business
       combination with UtiliCorp United Inc. ("UtiliCorp").
    
 
   
           I  also want you to  understand clearly that our  Board has not been,
       and will  not  be,  influenced  by your  unsubtle  efforts  at  corporate
       intimidation.  KCPL shareholders will vote on the issuance of KCPL shares
       required to accomplish the UtiliCorp merger, and the vote will be decided
       by a majority of all shares present and entitled to vote at the  meeting.
       This  is democracy in its purest form.  We are fully aware that you would
       prefer that the UtiliCorp merger be subject to a two-thirds supermajority
       voting requirement, where a minority of shares could thwart the wishes of
       a substantial majority.  We also  fully recognize that  your position  is
       designed  to further the interests of your own shareholders -- not KCPL's
       --and any protestations to the contrary will fool no one.
    
 
   
           The following are some of the more significant factors considered  by
       the  Board in rejecting Western's revised proposal (including some points
       which I discussed with you as early as March 1995).
    
 
   
       -WESTERN FACES SIGNIFICANT RATE REDUCTIONS.
    
 
   
           In connection with Western's acquisition  of Kansas Gas and  Electric
       Company  ("KGE") in 1991,  the Kansas Corporation  Commission (the "KCC")
       ordered that all merger savings (over and above an acquisition adjustment
       that is inapplicable  here) should be  shared equally between  ratepayers
       and shareholders. But, as you well know, Western has not yet adjusted its
       rate  levels to  reflect the  savings achieved  in the  KGE merger.  As a
       result, Western  is currently  embroiled  in rate  reduction  proceedings
       before the KCC.
    
 
   
           We believe that the KCC will impose rate reductions on Western far in
       excess  of the $8.7  million per year  over seven years  that Western has
       proposed. Western has implicitly  admitted that it  can afford to  reduce
       its earnings by at least an additional $50 million per year by requesting
       the  KCC's permission to accelerate depreciation  on the Wolf Creek plant
       by that annual amount.  Indeed, the staff of  the KCC has recommended  an
       immediate  rate reduction of  $105 million. We believe  that the KCC will
       address Western's overearnings  by ordering  significant rate  reductions
       and will not permit Western to keep such overearnings.
    
 
   
       -
    
   
        RATE REDUCTIONS IMPERIL WESTERN'S ABILITY TO DELIVER PROMISED DIVIDENDS.
    
 
   
           The  implementation of the KCC  staff's recommended $105 million rate
       reduction would have a significant negative impact on Western's cash flow
       and earnings. If  the $105  million rate reduction  is implemented,  then
       virtually  all of Western's  projected earnings for  1998 (as reported in
       the Western materials distributed  to analysts on June  17, 1996, but  as
       adjusted  for the  rate decrease  recommended by  the KCC  staff) will be
       required to pay the dividends

       promised to KCPL shareholders. Even if the KCC orders a rate decrease  of
       only   $80   million,   approximately   three-fourths   of   the  staff's
       recommendation, over 90% of Western's  projected earnings for 1998  could
       be  required to  make the promised  dividend payments. In  light of these
       facts, the Board does  not believe that  Western's dividend promises  are
       credible.
    
 
   
       -WESTERN'S  RATE DISPARITY BETWEEN KGE AND KPL ELECTRIC CUSTOMERS AMOUNTS
        TO AT LEAST $171.3 MILLION ANNUALLY.
    
 
   
           There is  a significant  disparity among  the rates  charged to  your
       customers.  The rates charged to KGE  customers were to have been reduced
       in connection with your acquisition of KGE. However, testimony before the
       KCC indicates that if the rates charged to KGE customers were reduced  to
       equal  the rates  charged to KPL  customers, Western would  suffer a $171
       million revenue reduction. Thus, even  if the KCC follows the  suggestion
       of its staff and the entire $105 million annual rate reduction is applied
       to   KGE  customers,  Western  would  still  face  a  rate  disparity  of
       approximately  $65  million  per  year.  Given  these  facts,  the  Board
       questions Western's commitment to sharing prospective merger savings with
       KCPL customers. In addition, the Board believes that Western will have to
       address  the rate disparity by lowering  rates for its KGE customers, and
       the Board does not  believe that revenues from  KCPL customers should  be
       used to subsidize a rate reduction for KGE customers.
    
 
   
       -
    
   
        RECENTLY,  WESTERN  BEGAN THE  40-YEAR  AMORTIZATION OF  THE ACQUISITION
        PREMIUM FOR KGE OF APPROXIMATELY $20 MILLION ANNUALLY.
    
 
   
           As a result of  the KGE acquisition, Western  must amortize the  $801
       million  acquisition premium at the rate of approximately $20 million per
       year over  a period  of forty  years, only  a portion  of which  will  be
       recovered  in rates. This significant, ongoing  and long-term burden is a
       liability  that  the  Board  does  not  believe  KCPL  shareholders   and
       ratepayers should be forced to share.
    
 
   
       -
    
   
        A COMBINATION OF KCPL AND WESTERN WOULD CONCENTRATE RISK.
    
 
   
           A  combined  KCPL/Western  entity would  own  94% of  the  Wolf Creek
       nuclear plant, concentrating a significant amount of capital and risk  in
       a  single asset. The Board believes that  it would be preferable to avoid
       additional  concentration  of  risk  in   Wolf  Creek.  In  contrast,   a
       KCPL/UtiliCorp entity would own only 47% of Wolf Creek.
    
 
   
       -A  COMBINED KCPL/UTILICORP ENTITY WOULD  BE BETTER POSITIONED TO COMPETE
        IN A DEREGULATED MARKET.
    
 
   
           A merger with UtiliCorp provides KCPL  with access to new markets  in
       several  states  and  foreign  countries,  diversifies  KCPL's  risks  by
       providing entry into nonregulated energy related businesses, and provides
       KCPL with  the competitive  advantages  of UtiliCorp's  successful  brand
       name,  EnergyOne. A merger  with Western would provide  KCPL with none of
       these immediate  advantages. UtiliCorp  is  much better  positioned  than
       Western to compete in a deregulated utility market.
    
 
   
       -WESTERN'S  SYNERGIES  CLAIMS ARE  UNREALISTIC  AND WESTERN  WILL  NOT BE
        ALLOWED TO RETAIN 70% OF THE SAVINGS RESULTING FROM A MERGER WITH KCPL.
    
 
   
           The  Board  believes,  based  on  a  review  of  Western's  synergies
       analysis,  that  Western has  significantly  overestimated the  amount of
       savings that would result  from a KCPL/Western combination.  Furthermore,
       Western's assumption in its KCC filings that it will be allowed to retain
       70% of the savings resulting from a merger with KCPL is inconsistent with
       applicable precedent. The KCC, in its order authorizing the merger of KGE
       and  Western's predecessor, Kansas  Power and Light  Co., required merger
       savings (over and  above an acquisition  adjustment that is  inapplicable
       here)  to  be  shared  equally  between  shareholders  and  customers. In
       addition, the staff  of the  Missouri Public Service  Commission, in  the
       pending  Union Electric/ CIPSCO merger,  is recommending an equal sharing
       of merger savings between shareholders
    
 
                                       44
<PAGE>
   
       and customers. As  you know, Western  will need the  approval of both  of
       these  regulatory agencies  for any merger  with KCPL. In  light of these
       precedents, it appears unrealistic to assume that Western will be able to
       keep 70% of merger savings.
    
 
   
           As a result of the Board's  conclusion that Western will not  realize
       its  forecasted amount of sav- ings,  and the Board's belief that Western
       will not be able  to retain its expected  portion of whatever savings  it
       does  realize,  the  Board  does  not  believe  that  Western's financial
       forecasts are credible.
    
 
   
       -WESTERN'S "NO LAYOFFS" PROMISE IS NOT CREDIBLE.
    
 
   
           Western has stated that  no layoffs would  result from its  proposal.
       However,  the synergy analysis filed by  Western with the KCC stated that
       531 employee positions would be eliminated and assumed that all resulting
       savings would be  available by  January 1,  1998. In  light of  Western's
       admission  in its proxy materials that a hostile transaction could not be
       completed until the end of 1997, the Board does not believe that  Western
       could achieve those 531 "reductions" without laying off KCPL employees.
    
 
   
                                        *  *  *
    
 
   
           The  proposed Western  transaction would require  our shareholders to
       exchange their KCPL stock, not for cash, but for Western stock. The value
       of such Western shares is therefore  very much at issue. For the  reasons
       stated  in this  letter, among others,  we have  significant doubts about
       Western's business prospects and believe that Western's earnings will not
       be sufficient  to sustain,  let alone  grow, dividends.  Accordingly,  we
       firmly  believe  that the  proposed  Western transaction,  in  which KCPL
       shareholders would receive shares  of Western stock, is  not in the  best
       interests  of  our  shareholders  and we  reject  it.  Moreover,  we have
       concluded in  view of  the  factors enumerated  in  this letter  and  our
       conclusions  regarding the Western proposal and  the value of the Western
       shares, that it would serve no purpose to meet with you.
    
 
   
           You have made many  promises that we do  not believe Western will  be
       able  to  keep.  Your  dividend promises  are  contingent  on unrealistic
       earnings forecasts that are undermined by inflated merger savings and the
       likelihood that  the  KCC  will impose  significant  rate  reductions  on
       Western. Your rate reduction promises ring hollow, because your customers
       are still waiting for tens of millions of dollars of rate reductions that
       should  have resulted from  the acquisition of KGE.  Your promise that no
       employees will be laid off  is in conflict with  your KCC filings. We  do
       not  intend  to  risk  the  future  of  our  company  and  its customers,
       employees, shareholders and other constituencies on your hollow promises.
    
 
   
           Western  faces  serious  problems  relating  to  the  impending  rate
       reduction  and rate disparity issues discussed above. These problems need
       to be resolved by  Western's management and Board  of Directors, and  the
       consequences  of your actions should be  borne by your customers and your
       shareholders alone.  Our  Board will  not  permit Western  to  solve  its
       internal business problems by merging with KCPL.
    
 
   
                                          Sincerely,

REASONS FOR THE MERGERS; RECOMMENDATIONS OF THE BOARDS OF DIRECTORS
    In  considering the recommendations of the KCPL Board and the UCU Board with
respect to the  Mergers, stockholders should  be aware that  certain members  of
KCPL's  and UCU's management  and Boards of Directors  have certain interests in
the Mergers that are in  addition to the interests  of stockholders of KCPL  and
UCU    generally.    See    "THE   MERGERS    --    Conflicts    of   Interest,"
"-- Certain Arrangements Regarding the  Directors and Management of Newco,"  "--
Employment Agreements" and "-- Employee Plans and Severance Agreements."
 
    KCPL.   The KCPL Board  believes that the terms of  the Mergers are fair to,
and in the  best interests  of, KCPL, its  shareholders, its  employees and  its
customers.  Accordingly, the KCPL  Board, by a unanimous  vote, has approved the
Merger Agreement and the Mergers and recommends that the holders of KCPL  Common
Stock  approve the  Share Issuance.  The KCPL  Board believes  that the electric
utility industry will undergo tremendous  upheaval in the wake of  deregulation.
As  barriers to the  mergers of utilities  come down, the  utility industry will
come to more closely resemble other industries where competition is intense  and
only  the strongest companies succeed. The KCPL Board is convinced that in order
to succeed in such a  market, KCPL must be a  customer focused, low cost  energy
supplier  with diversified  assets and the  financial resources  to leverage its
strengths. The KCPL Board believes that  the Mergers will allow KCPL to  achieve
these goals, and that this unique opportunity for KCPL and UCU to merge provides
unusual  opportunities for KCPL shareholders to participate in the growth of the
combined company. This growth will  derive from operating efficiencies  obtained
from  economies of scale; the  more efficient use of  the current investments in
generating and transmission capacity and advanced information systems;  improved
opportunities  for cost  reductions; revenue  enhancements made  possible by the
combination of  KCPL and  UCU  (see "--  Enhancement of  Financial  Performance"
below);  domestic  market  diversification,  due  to  UCU's  presence  in  eight
different states, leading to reduced risk; international market diversification,
due to  UCU's  presence  in  five foreign  countries,  both  reducing  risk  and
affording  unusual  growth opportunities;  the addition  of  natural gas  to the
products and services offered to customers and the potential for attracting  new
customers  through the  offering of such  additional service;  and the long-term
financial capability of  a larger company.  In the judgment  of the KCPL  Board,
these  factors combine to offer shareholders improved opportunities for earnings
and dividend growth  and an  enhanced ability to  manage risk  in the  uncertain
environment created by the changing utility market.
 
    In  reaching this conclusion, the KCPL Board considered: (i) the prospective
financial strength of each company individually and the benefits of  combination
discussed  above, particularly in light of the KCPL Board's familiarity with and
review of KCPL's business, operations, financial condition and earnings on  both
an  historical  and prospective  basis,  and the  KCPL  Board's belief  that the
strategic alliance with UCU will  provide opportunities to achieve benefits  for
KCPL's  shareholders and customers that  would not be available  if KCPL and UCU
remained as separate  enterprises; (ii)  current industry,  economic and  market
conditions  which encourage consolidation to reduce  risk and create new avenues
for earnings  growth  as discussed  under  "THE  MERGERS --  Background  of  the
Mergers"  above; (iii) KCPL's estimated cost savings resulting from the Mergers,
which the KCPL Board believes to be  credible and achievable, and the effect  of
such  savings on the competitive position of  Maxim; (iv) the enhanced access to
capital that Maxim  would enjoy due  to the  size of the  combined company;  (v)
UCU's  experience in energy related  non-regulated businesses; (vi) the proposed
structure of the  transaction and the  terms of the  Merger Agreement and  other
documents  to  be executed  in  connection with  the  Mergers which  provide for
reciprocal representations and warranties, conditions  to closing and rights  to
termination,  and balanced  rights and obligations;  (vii) that  the Mergers are
expected to be treated as a tax-free reorganization and to be accounted for as a
pooling-of-interests transaction (which avoids  the reduction in earnings  which
would  result  from the  creation and  amortization  of goodwill  under purchase
accounting); (viii) the expected benefits  of the Mergers discussed below  under
"-- Expected Benefits of the Mergers"; (ix) the Exchange Ratio in the Mergers as
compared to the exchange ratios in the Original Merger and the increase in value
to  KCPL shareholders in the  Mergers as compared to  the Original Merger, which
increase in value is due to an  increase in the percentage interest held in  the
combined company by KCPL shareholders from 55% to 57%;
 
                                       46
<PAGE>
   
(x)  that approval of  the Share Issuance  requires the affirmative  vote of the
holders of a  majority of  the shares  of KCPL  Common Stock  voting thereon  as
compared  to the Original Merger which required the favorable vote of two-thirds
of the outstanding shares of KCPL  Common Stock, that this change increased  the
likelihood  of consummation  of the  combination by  eliminating the  power of a
minority of KCPL shareholders to effectively veto what the majority approve, and
that Western Resources would likely commence litigation challenging this  aspect
of  the Merger Agreement (which latter consideration  led the KCPL Board to deem
it advisable to commence litigation seeking declaratory judgments concerning the
legality of the Merger Agreement and  its adoption. See "THE MERGERS --  Certain
Litigation.");  and (xi) the written opinion of Merrill Lynch to the effect that
the Exchange Ratio is fair to holders  of KCPL Common Stock (other than UCU  and
its  affiliates) from a financial  point of view. In  that regard, management of
KCPL  has  advised  Merrill  Lynch  that  it  believes  there  are   significant
contingencies  and uncertainties associated with  the Proposed Western Resources
Offer (collectively with  the Western Resources'  related proxy statement  dated
May  3,  1996, the  "WR  Proposal") due  to  the speculative  nature  of certain
assumptions made by  Western Resources in  the WR Proposal  relating to  Western
Resources'  ability  to  achieve  and retain  certain  estimated  aggregate cost
savings, and the likelihood of  substantially greater rate reductions  affecting
Western  Resources in  a pending rate  proceeding than those  assumed by Western
Resources. Management of KCPL  has also advised Merrill  Lynch that it  believes
that the WR Proposal is not consistent with the strategic objectives of KCPL. In
view  of  the  foregoing, Merrill  Lynch  was not  asked  by the  KCPL  Board to
consider, and Merrill Lynch did not consider, the WR Proposal in arriving at its
opinion. In determining that the Mergers are  fair to and in the best  interests
of  its shareholders, the KCPL  Board considered the above  facts as a whole and
did not assign specific or relative weights to them.
    
 
   
    In making  its  recommendation in  favor  of  the Mergers,  the  KCPL  Board
considered  the Proposed Western Resources Offer as amended to reflect the terms
of the June 17 Announcement but  determined to proceed with the Mergers  because
of  the benefits of a transaction with UCU to KCPL's shareholders, customers and
employees and  the Kansas  City area.  The KCPL  Board also  considered  certain
additional factors concerning the Proposed Western Resources Offer as amended to
reflect   the  terms   of  the   June  17   Announcement,  including:   (i)  the
incompatibility between (x)  the KCPL Board's  desired strategy of  diversifying
risk  by entering into  new markets and unregulated  businesses through a merger
with UCU, and (y) the concentrated  risk and lack of diversification that  would
result  from a KCPL/Western  Resources combined company,  which would operate in
relatively uniform climatic, geographic and regulatory markets, and which  would
concentrate  a substantial amount of capital and  risk in the Wolf Creek nuclear
power facility; (ii) the likelihood that the Kansas State Corporation Commission
(the "Kansas Commission") would impose  rate reductions on Western Resources  in
excess  of the  $8.7 million requested  by Western Resources,  which concern was
recently exacerbated by the recommendation of the staff of the Kansas Commission
that Western Resources' rates be reduced by $105 million; (iii) the KCPL Board's
belief, based on a  review of Western Resources  synergy analysis, that  Western
Resources  significantly overestimated the  amount of savings  that would result
from a KCPL/Western  Resources combination;  (iv) the KCPL  Board's belief  that
Western  Resources would not be able to retain 70% of the merger related savings
due to  (x)  the Kansas  Commission's  stated desire  for  an equal  sharing  of
benefits between utilities and their customers, which desire is evidenced in the
order  approving the merger of Western  Resources' predecessor, Kansas Power and
Light Co. ("KPL"), and Kansas Gas and Electric Company ("KGE") and (y) the  fact
that  in the  pending Union  Electric/CIPSCO merger,  the staff  of the Missouri
Public Service Commission  is recommending  an equal sharing  of merger  savings
between shareholders and customers; (v) the fact that Western Resources is under
an  order from  the Kansas Commission  to amortize an  acquisition adjustment of
approximately $800 million incurred in connection with the merger of KPL and KGE
over a  forty-year period  commencing August  1995; (vi)  the condition  to  the
Proposed  Western Resources  Offer that  90% of  the outstanding  shares of KCPL
Common Stock must  be tendered, and  the KCPL  Board's belief that  such a  high
threshold  would not be met; (vii) the  fact that the Proposed Western Resources
Offer is conditioned on the availability  of the pooling of interests method  of
accounting,  when the Proposed Western Resources Offer would permit the exercise
of certain stock
    
 
                                       47
<PAGE>
   
appreciation rights  held  by KCPL  officers  that would  cancel  related  stock
options  and allow the holders to receive  cash payments for securities that are
essentially the same as common stock,  which would violate paragraph 47b of  APB
Opinion No. 16 of the Accounting Principles Board and thereby prohibit using the
pooling  of  interests  method  of  accounting;  (viii)  the  fact  that Western
Resources stated  that  no  layoffs  would  result  from  the  Proposed  Western
Resources  Offer, while the synergy analysis filed by Western Resources with the
Kansas Commission stated  that 531  employee positions would  be eliminated  and
assumed  that all resulting savings would be  available by January 1, 1998; (ix)
the disparity among  rates charged to  customers of Western  Resources, and  the
negative impact upon Western Resources and current KCPL customers of any efforts
to  address  such  disparity;  (x) the  KCPL  Board's  doubts  regarding Western
Resources' commitment  to  Kansas  City  charities  and  Kansas  City  community
development  efforts;  and  (xi)  the  validity  of  certain  assumptions  to be
contained in the opinions of Western Resources' tax counsel regarding whether or
not the  Proposed  Western  Resources  Offer would  be  treated  as  a  tax-free
transaction to KCPL shareholders, and the adverse affect on KCPL shareholders if
a  merger of KCPL and Western Resources  constituted a taxable transaction. As a
result of the KCPL Board's consideration of factors (ii), (iii) and (iv)  above,
the KCPL Board discounted the nominal value of Western Resources' various offers
because  of the significant contingencies  and uncertainties surrounding Western
Resources' financial  forecasts.  In particular,  as  discussed in  clause  (ii)
above,  the  KCPL Board  believes that  the Kansas  Commission will  impose rate
reductions on  Western Resources  in excess  of the  $8.7 million  requested  by
Western Resources, as evidenced by the recommendation of the Kansas Commission's
staff  that Western  Resources' rates  be reduced by  $105 million.  If the $105
million rate reduction is implemented, then virtually all of Western  Resources'
projected  earnings for  1998 (as  reported in  the Western  Resources materials
distributed to analysts on June 17, 1996, but as adjusted for the rate  decrease
recommended  by  the  Kansas  Commission  staff) will  be  required  to  pay the
dividends promised to KCPL shareholders. Even if the Kansas Commission orders  a
rate  decrease of only  $80 million, approximately  three-fourths of the staff's
recommendation, over 90% of Western Resources' projected earnings for 1998 could
be required to  make the  promised dividend  payments. As  discussed in  clauses
(iii) and (iv) above, the KCPL Board further believes that Western Resources has
significantly  overestimated the amount of merger  savings that it could realize
and significantly  underestimated  the  amount  of  any  realized  savings  that
regulatory  authorities  would  require  Western  Resources  to  share  with its
customers.
    
 
    THE KCPL BOARD, BY A UNANIMOUS VOTE, HAS APPROVED THE MERGER AGREEMENT,  THE
MERGERS AND THE TRANSACTIONS CONTEMPLATED THEREBY AND BELIEVES THAT THE TERMS OF
THE  MERGERS ARE FAIR TO, AND IN THE BEST INTERESTS OF, KCPL'S SHAREHOLDERS. THE
KCPL BOARD RECOMMENDS A VOTE FOR APPROVAL OF THE SHARE ISSUANCE, FOR APPROVAL OF
THE MAXIM STOCK INCENTIVE PLAN AND FOR APPROVAL OF THE MAXIM MIC PLAN.
 
    UCU.  The UCU Board believes that the terms of the Mergers are fair to,  and
in  the best interests of, UCU  and its stockholders and customers. Accordingly,
the UCU Board,  by a unanimous  vote of  the directors, has  adopted the  Merger
Agreement  and recommends both approval  of the Merger Agreement  and of the UCU
Merger by the stockholders of UCU. The UCU Board believes that the Mergers  will
provide  opportunities to  achieve benefits  for its  stockholders and customers
that would  not  be  available if  UCU  and  KCPL were  to  remain  as  separate
enterprises  and that, as a result of the combination of UCU's and KCPL's common
stock equity, management,  personnel and  technical expertise, Maxim  will be  a
company  with  great  financial  strength  and  will  be  able  to  compete more
effectively in  both  its  regulated  and unregulated  markets.  The  UCU  Board
believes  that  the Mergers  will  allow UCU  stockholders  to benefit  from the
financial stability of KCPL  and its low-cost,  efficient manner of  operations.
This,  in turn, will give Maxim increased flexibility and leverage in financing.
In reaching its conclusions, the UCU Board considered the financial performance,
condition, business operations and prospects of  each of UCU and KCPL and  that,
on  a combined basis, the companies will likely have greater financial stability
and strength as a result of  the participation in the combined economic  climate
and growth of UCU and KCPL, the inherent increase in scale economies, the market
diversification  resulting from the combination and  the impact of the potential
operation efficiencies
 
                                       48
<PAGE>
and other synergies. As a result, the UCU Board believed that the Mergers  would
provide  opportunities to  achieve benefits for  UCU stockholders  that would be
greater than those available  if UCU remained a  separate entity. The UCU  Board
also  based its  conclusions on its  belief that current  industry, economic and
market conditions  will constrain  the ability  of public  utility companies  to
increase  earnings through additions to rate base, which as discussed above (see
"THE MERGERS -- Background of the Mergers"), indicates utilities should strongly
consider consolidation to reduce and diversify  risk, to create new avenues  for
earnings  growth, and  to create greater  efficiencies and  abilities to control
costs. The UCU Board  also considered (i) the  access the combined company  will
have  to the  resources of  Maxim in  diversifying its  operations to counteract
increased competition in the  utility industry; (ii)  the proposed structure  of
the  transaction as a merger of equals; (iii) that the proposed structure of the
transaction is expected  to be treated  as a tax-free  reorganization and to  be
accounted  for as a pooling-of-interests transaction (which avoids the reduction
in earnings which would  result from the creation  and amortization of  goodwill
under purchase accounting); (iv) the written opinion of DLJ, dated May 19, 1996,
that,  subject to  the assumptions  made, matters  considered and  limits of the
review undertaken as set forth in such opinion, the Exchange Ratio is fair, from
a financial point  of view, to  holders of  UCU Common Stock;  (v) the  proposed
terms  of the  Merger Agreement;  and (vi)  the other  expected benefits  of the
Mergers discussed below. In determining that the Mergers are fair to and in  the
best  interests of its stockholders, the UCU Board considered the above facts as
a whole and did not assign specific or relative weights to them.
 
    THE UCU BOARD  HAS UNANIMOUSLY  APPROVED OF  THE MERGER  AGREEMENT, THE  UCU
MERGER  AND THE TRANSACTIONS CONTEMPLATED THEREBY AND BELIEVES THAT THE TERMS OF
THE MERGERS ARE FAIR TO, AND IN  THE BEST INTERESTS OF, UCU'S STOCKHOLDERS.  THE
UCU  BOARD RECOMMENDS A  VOTE FOR APPROVAL  OF THE MERGER  AGREEMENT AND THE UCU
MERGER.
 
    EXPECTED BENEFITS OF THE MERGERS.   The Board of  Directors of each of  KCPL
and UCU believe that the expected benefits of the Mergers will include:
 
    -Diversification -- The Mergers will result in the increased ability of KCPL
     and  UCU  to diversify  their existing  operations through  acquisitions of
     primarily energy related, non-regulated assets or entities, development and
     marketing of  new products  and use  of new  technology, thereby  assisting
     Maxim  in counteracting potential decreases  in revenue caused by increased
     competition in the utility industry.
 
    -Customer Service  -- Maxim  will  rapidly be  able  to develop  and  deploy
     innovative  customer services, especially  those using advanced information
     technology. These services will reach a  wider customer base than would  be
     possible with each company operating alone.
 
    -Strategic Acquisitions -- The Mergers will provide a larger and more stable
     platform  from which  to acquire  properties that  mesh with  the strategic
     intent of the combined enterprise.
 
    -Coordination of Dispatch  -- The  coordination of the  dispatch of  Maxim's
     electric  generating units  and transmission facilities  should permit more
     efficient utilization of  Maxim's resources to  meet the combined  system's
     requirements and provide continued low-cost energy to Maxim's customers.
 
    -Increased  Purchasing  Coordination  -- The  coordination  of  purchases of
     products including  fuel, electric  energy and  natural gas  should  enable
     Maxim to lower costs of such items through economies of scale and increased
     bargaining  strength  and  should contribute  to  more  efficient inventory
     management.
 
    -Management of Price Increases -- The operating cost savings resulting  from
     the  Mergers will allow Maxim to  hold future electric rate increases below
     what would  otherwise  be  necessary for  the  individual  utilities,  thus
     maintaining  the cost advantage currently enjoyed  by customers of KCPL and
     UCU.
 
    -Generation Planning Benefits --  Due to the greater  size and diversity  of
     electric generating units which will result from combining the KCPL and UCU
     systems,  Maxim can achieve the same  level of reliability for the combined
     system with a lower reserve margin than that
 
                                       49
<PAGE>
     currently employed by either KCPL or UCU. Future generation planning should
     benefit Maxim by improving the existing ability of KCPL and UCU to  satisfy
     customer demand load by lowering reserve requirements, diversifying periods
     of peak customer demands and optimizing base-load plant usage. In addition,
     the Mergers will permit the two utilities to reduce the consequences of the
     loss  of a major base-load power plant.  Major extended outages can be very
     costly both to utilities  and to their  customers. Protection against  such
     costs  include  backup capacity  and  provisions for  alternative base-load
     sources. The risk to any one utility of having problems at any one facility
     may also be mitigated through coordinated system planning and scheduling of
     power plant maintenance in a large pool of base-load generating units.
 
    -Peak Demand Reduction Efforts -- As  members of a coordinated system,  KCPL
     and  UCU will  be able to  share their expertise  in demand-side management
     techniques. Demand-side management includes the reduction of peak loads  of
     customers  through  pricing,  energy  efficiency  programs  and  other load
     management programs.
 
    -Deferral of Capital  Investments -- It  is anticipated that  Maxim will  be
     able  to eliminate or  defer certain capital investments  that KCPL and UCU
     otherwise would  have  to make  as  separate entities.  These  include  the
     deferral  or  elimination of  planned  peaking capacity  additions  and the
     deferral of planned base-load capacity additions in the early 2000s.
 
    -Operations and  Maintenance Activities  --  The coordinated  allocation  of
     manpower,  equipment,  technology  and  other  resources  should  result in
     benefits to customers of the two utilities. Sharing of stored inventory and
     other materials should  be attainable and  may result in  reduced costs  to
     both utilities.
 
    -Expanded  Management Resources -- In combination, KCPL and UCU will be able
     to draw on a larger and more diverse mid- and senior-level management  pool
     to   lead  the  combined  Maxim  forward  in  an  increasingly  competitive
     environment for the delivery of energy.
 
    -Increased Size and Stability -- As a larger entity, Maxim will have a  more
     diverse generating, transmission and customer base. In addition, Maxim will
     have  a larger asset base than either  KCPL or UCU, enhancing its access to
     capital markets.
 
    -Economic Development Efforts  -- A larger,  more diverse service  territory
     and  competitive rates should  broaden the range  of opportunities KCPL and
     UCU can offer existing and potential customers, making the combined service
     area more attractive to business  and helping to stimulate economic  growth
     in the region.
 
    -Reduced  Administrative  Costs --  It is  anticipated that  as a  result of
     combining  staff  functions,   within  several  years,   Maxim  will   need
     approximately  200 fewer employees than KCPL and UCU would need without the
     Mergers. These  work force  reductions  will be  accomplished, as  much  as
     possible, through restrictions on hirings (which are currently in effect at
     both  companies), attrition  and voluntary  early retirement.  In addition,
     some savings in areas such as insurance, regulatory costs and auditing  and
     consulting fees should be realizable.
 
    -Community  Involvement -- Maxim will be  a stronger partner in the economic
     development efforts  of  the  communities  KCPL  and  UCU  now  serve.  The
     philanthropic  and  volunteer  programs  currently  maintained  by  the two
     companies will be  continued with  the enhanced resources  of the  combined
     entity. Moreover, Maxim's substantial customer base will give it a stronger
     voice in national policy debates on issues affecting the region.
 
CERTAIN FORWARD-LOOKING INFORMATION
 
    This  Joint  Proxy  Statement/Prospectus  contains  certain  forward-looking
information including information provided under the captions "-- Synergies from
the Mergers,"  "--  Additional Operational  Benefits,"  and "--  Enhancement  of
Financial  Performance." The  Private Securities  Litigation Reform  Act of 1995
provides a  new  "safe  harbor" for  forward-looking  information  to  encourage
companies  to provide prospective information about their companies without fear
of litigation so long as such  information is identified as forward-looking  and
is accompanied by meaningful cautionary statements identifying important factors
that could cause actual results to differ materially from those projected in the
information.  KCPL  and  UCU  identify  the  following  important  factors which
 
                                       50
<PAGE>
could cause KCPL's, UCU's and Maxim's  actual results to differ materially  from
any  such results which  might be projected, forecast,  estimated or budgeted by
KCPL, UCU  or Maxim  in forward-looking  information. All  of such  factors  are
difficult  to predict and many of which are  beyond the control of KCPL and UCU.
Accordingly, while  KCPL and  UCU believe  that the  assumptions underlying  the
forward-looking  information are reasonable  for purposes of  the development of
estimates of revenue enhancements and cost  savings, there can be no  assurances
that  such  assumptions  will approximate  actual  experience or  that  all such
revenue enhancements  and cost  savings will  be realized,  and in  such  event,
actual  results  could  differ  materially from  the  predictions  herein. These
important factors  include: (a)   future  economic conditions  in the  regional,
national  and international  markets in which  KCPL and UCU  compete; (b) state,
federal and foreign regulation, including limitations on the amount of synergies
Maxim will be able to keep  and possible additional reductions in regulated  gas
and  electric rates;  (c) weather  conditions; (d)  financial market conditions,
including, but not limited to, changes  in interest rates; (e) inflation  rates;
(f) changing competition, including, but not limited to, the deregulation of the
United  States electric utility industry, and  the entry of new competitors; (g)
the ability to carry out marketing and sales plans; (h) the ability to eliminate
duplicative administrative  functions; (i)  the  ability to  achieve  generation
planning  goals  and the  occurrence of  unplanned  generation outages;  (j) the
ability to defer  or eliminate certain  capital investments which  KCPL and  UCU
would  have to make as separate companies;  (k) the ability to enter new markets
successfully and capitalize on growth opportunities in non-regulated businesses;
and (l)  adverse changes  in  applicable laws,  regulations or  rules  governing
environmental, tax or accounting matters.

SYNERGIES FROM THE MERGERS
 
    KCPL  and UCU have jointly  identified a number of  synergies related to the
Mergers which their managements believe can be achieved. KCPL and UCU anticipate
that a portion of these savings  from regulated operations will be allocated  to
their  ratepayers by state regulatory authorities in the various states in which
Maxim will conduct  business. The companies  retained Ernst &  Young in 1995  to
assist  in identifying, for their regulatory  filings, the synergies relating to
combining the regulated utility operations pursuant to the Original Merger.  The
Ernst & Young report, dated March 29, 1996, which identified potential synergies
of $636 million, was filed with the FERC on March 29, 1996 and complies with the
filing  requirements  of  the  FERC.  The  Ernst  &  Young  synergies  amount is
consistent with  the  Joint Proxy  Statement/Prospectus,  dated April  4,  1996,
relating  to the  Original Merger.  In addition,  the companies  have identified
other operational  efficiencies in  both  regulated and  non-regulated  segments
which  are  discussed  below  under  the  captions  "--  Additional  Operational
Benefits" and "-- Enhancement  of Financial Performance."  This section and  the
sections  captioned "-- Additional Operational  Benefits" and "-- Enhancement of
Financial Performance" include certain forward-looking information and should be
read in  conjunction  with  the "Certain  Forward-Looking  Information"  section
above.

MATERIAL ASSUMPTIONS UNDERLYING COST SAVINGS FROM SYNERGIES
 
    The  material assumptions for  the cost savings which  are anticipated to be
realized from the Mergers are as follows:
 
    - All synergies discussed below are estimated for a 10-year period.
 
    - In calculating synergies by  year, an inflation rate  of 3.5% was  assumed
      for the 10-year period.
 
    - All synergies outlined below represent approximate amounts.
 
    - No synergies were evaluated which relate to non-regulated businesses.
 
    - Labor  cost estimates are  based on an analysis  of nine labor categories:
      executive, management, professional,  clerk, plant operator,  supervisors,
      craft labor, customer service supervisors and associates.
 
    - Position  reductions (which, together with avoided hires, are shown on the
      above chart as reductions in Full-Time Equivalent employees ("FTEs"))  are
      expected  to occur over a 10-year period.  The managements of KCPL and UCU
      believe, based on historical attrition patterns at KCPL and UCU, that such
      reductions should  be  attained  entirely through  attrition  and  avoided
      hires.
 
    - All  existing  cost savings  initiatives are  excluded from  the synergies
      report.
 
    - In the discussion below, fixed charges represent the annual carrying costs
      of avoided capital  projects. Carrying costs  include depreciation,  taxes
      other than income taxes, and interest.
 
    - Avoided  capital costs are  incurred on June 30,  while FTE reductions are
      implemented on January 1.
 
    The discussion below provides a brief description of the synergy savings  by
category  as detailed in the table above which is derived from the Ernst & Young
report and  is limited  to the  material synergy  areas with  smaller  synergies
aggregated in a category total. The major captions below correspond to the above
chart.
 
GENERATE ENERGY
 
    FUEL  PROCUREMENT -- Expected savings of $3.8 million result from reductions
in fuel procurement, labor and reduced inventory balances.
 
    SYSTEM GENERATION -- Combined dispatch of system generation results in  fuel
and   variable  operation  and  maintenance  costs  ("O&M")  savings  which  are
anticipated to  be $107.4  million. Construction  of less  expensive  generation
capacity  enabled by the Mergers could result in reductions of plant capital and
O&M charges. These  reductions are expected  to include $88.6  million of  fixed
charges and $72.5 million of O&M savings.
 
    GENERATION  PROCESS -- Consolidation of  the system operations should result
in estimated labor savings of $30.5 million. Operation of one energy  management
system  should reduce costs  by an estimated  $3.8 million. Avoiding maintenance
contract costs by using KCPL crews at UCU's Sibley plant is anticipated to  save
$6.0 million. Other synergies were estimated that total $2.6 million.
 
DISTRIBUTE AND TRANSPORT ENERGY
 
    TRANSMISSION  --  Delay  or  avoidance  of  the  construction  of  redundant
transmission lines  and  substations  and  the avoided  purchase  of  parts  and
equipment  resulting from  the Mergers  is anticipated  to save  $8.7 million in
fixed charges. Consolidation  of transmission  staffing is  anticipated to  save
$6.7 million.
 
    DISTRIBUTION  --  Delay  or  elimination  of  redundant  distribution system
capital projects  should  reduce  fixed  charges by  $3.1  million.  Merging  of
distribution,  engineering,  planning,  and  design  functions  should  save  an
estimated  $3.4  million  in  staffing  costs.  Combining  dispatching   efforts
 
                                       53
<PAGE>
should reduce labor costs by $5.9 million and fixed charges by an estimated $3.2
million, the latter related to the avoidance of certain systems. Other potential
synergies were identified that total $1.1 million.
 
SERVE CUSTOMERS
 
    CUSTOMER  SERVICE -- Anticipated savings of  $3.1 million should result from
consolidating customer call centers.  Other potential synergies were  identified
that total $1.3 million.
 
PURCHASING/MATERIALS MANAGEMENT
 
    PURCHASING  AND  MATERIALS  MANAGEMENT  -- Based  on  a  sample  of vendors'
materials and services, discounts are  expected to be obtained through  supplier
consolidation  and leveraging the  larger scale of  purchases. These savings are
estimated at $34.5 million. Labor savings of $14.6 million are anticipated  from
consolidating   procurement  and  warehouse   functions.  Other  synergies  were
estimated that total $1.7 million.
 
    FLEET AND  FACILITIES  --  Consolidation of  headquarters'  buildings,  call
centers  and  other  facilities  should result  in  estimated  savings  of $21.9
million. Estimated fleet maintenance savings of $5.5 million should be  achieved
by  consolidating functions  into existing  internal functions.  Other synergies
were estimated that total $2.4 million.
 
INFORMATION TECHNOLOGY ("IT")
 
    ENTERPRISE SUPPORT --  Avoidance of  the purchase of  duplicate systems  for
financial  support and  certain transmission  and distribution  functions should
result in  anticipated savings  for fixed  charges of  $36.0 million  and  $10.4
million of labor based O&M costs.
 
    CUSTOMER  INFORMATION SYSTEM ("CIS") -- Both  companies had plans to replace
their CIS  systems. Developing  one system  for both  companies should  save  an
estimated  $15.2 million of  fixed charges. Other  synergies were estimated that
total $1.0 million.
 
    DATA CENTER CONSOLIDATION -- The consolidation of computer data centers  and
the elimination of duplicate functions should save an estimated $33.0 million in
labor and other costs.
 
    OTHER  IT  ISSUES  --  Consolidating  the  telecommunication  and technology
activities of the  two companies  should save  an anticipated  $13.3 million  of
labor and other costs.
 
EXECUTIVE AND ADMINISTRATIVE SUPPORT
 
    SUPPORT  FUNCTION FINANCIAL LABOR  -- Labor reductions  anticipated from the
elimination  of  duplication  in   accounting,  planning  and  budgeting,   cash
management,  investor relations and  internal audit should  result in savings of
$35.4 million.
 
    SUPPORT FUNCTION NONFINANCIAL LABOR -- Labor reductions anticipated from the
elimination  of  duplication   in  human  resources,   rates  and   regulations,
environmental,  governmental relations, communications,  and legal should result
in savings of $16.4 million.
 
    SUPPORT-RELATED FINANCIAL  EXPENDITURES  --  Estimated  synergies  of  $11.1
million  should be achieved  by combining activities  such as lockbox processing
and disbursements, lines of credit,  transfer agents and meetings with  analysts
and large stockholders. Risk management expense is estimated to decrease by $7.3
million  because of the  elimination of duplicate  coverage and reduced premiums
for the  combined  companies. Other  synergies  related to  accounting  and  tax
advisory services are anticipated to save $6.5 million.
 
    SUPPORT-RELATED  NONFINANCIAL EXPENDITURES --  Anticipated savings resulting
from the  elimination of  duplicate legal  and communication  efforts should  be
$11.6  million and  $3.4 million,  respectively. Other  synergies were estimated
that total $3.3 million.

    The combination of  the Missouri and  Kansas operations of  KCPL and UCU  is
expected  to produce benefits  of approximately $8.5  million, declining to $4.6
million by  the fourth  year, in  dispatch related  pre-tax savings  due to  the
substitution  of  low  variable  cost  KCPL  generated  power  for  UCU supplies
currently generated  by  UCU or  purchased  by  UCU. In  addition,  benefits  of
approximately  $1.3  million per  year in  production  pre-tax savings  at UCU's
Sibley power station were identified from the introduction of KCPL low cost coal
purchases as part of the fuel mix.
 
    A review of procurement  savings related to the  Mergers yields an  expected
pre-tax  savings increment of $2.1 million per year in non-generating small item
stock purchases and  related carrying  costs and in  contractual services.  This
review  also found approximately  $1.3 million per year  in pre-tax savings from
combined purchases of technical information  and an additional $2.5 million  per
year in pre-tax savings from the internalization of certain legal and regulatory
services.

ENHANCEMENT OF FINANCIAL PERFORMANCE
 
    The  Palmer Bellevue practice  of Coopers &  Lybrand Consulting assisted the
managements of  KCPL and  UCU  in their  development of  additional  information
relating  to Maxim's ability to enhance  its financial performance subsequent to
the Mergers by facilitating  discussions between KCPL and  UCU and by  reviewing
the methodologies utilized in the development of the additional information.
 
    KCPL  and UCU believe that their  combination offers a substantial alignment
of complementary capabilities  for growth  in a competitive  energy and  service
market.  There  are  valuable  benefits identified  below  that  arise  from the
combination of KCPL and UCU that stem from the rapidly developing  international
energy  markets, the expansion of  gas and electric marketing  in an open access
environment and the offering of new products and services to a combined customer
base.
 
    UCU believes that  it brings  entrepreneurial experience  as illustrated  by
carrying  out a ten-fold expansion  of revenues over the  past ten years through
foreign and  domestic utility  acquisitions,  independent power  investment  and
energy marketing ventures. KCPL believes that it is recognized for its financial
strength and management practices which have resulted in low cost generation and
superior  performance.  The combination  of  these capabilities  should position
Maxim for sustained expansion  in a competitive energy  market. The table  below
shows  the expected  benefits of the  enhancements broken  into three categories
with a discussion of each category following the table.

INTERNATIONAL
 
    Rapidly  developing  overseas  opportunities  in  utility  acquisitions  and
privatizations  as well as in power plant  development will be a strategic focal
point for Maxim.  Maxim will be  well positioned to  compete for these  projects
because  of the financial  foundation and operating  capabilities resulting from
the Mergers.  It  is  anticipated that  Maxim  will  be able  to  combine  UCU's
investment and operating experience in existing English-speaking utility markets
with KCPL's involvement in the small power production market in China and KCPL's
in-depth technical and operational expertise and financial strength.
 
    UCU has begun to refocus its gas marketing business in the United Kingdom to
reduce  gas supply costs in anticipation of  a fully open retail market in 1997.
The financial strength of KCPL should allow the United Kingdom gas marketing and
trading operation  to take  expanded  positions and  grow in  the  de-regulating
United Kingdom gas market.
 
    UCU  currently  has  investments  in  electric  distribution  businesses  in
Australia and New Zealand.  KCPL and UCU intend  to apply their operational  and
technical  skills and  ability to  access markets  to these  businesses. This is
expected to result in greater efficiencies and market share.
 
                                       56
<PAGE>
    Anticipated improvements in operational efficiencies from these  investments
are  expected  to  produce  incremental  pre-tax  income  which  ranges  between
approximately $16.4 million and  $30.2 million over  the four-year period  after
the Mergers.
 
ENERGY MARKETING
 
    The  combination of KCPL's low variable cost regional wholesale position and
financial strength  coupled  with  UCU's  pioneer status  in  gas  and  electric
marketing  is expected to provide growth opportunities in the power market. This
plan is consistent  with the new  conditions represented by  the April 24,  1996
issuance by the FERC of the electric open access Orders 888 and 889 and with the
potential for gas marketing within the KCPL electric service territory.
 
    AGP,  a subsidiary  of Aquila  and an  indirect subsidiary  of UCU, recently
reported to stockholders  that in 1995  it set company  records for natural  gas
throughput,  volumes  of extracted  natural gas  liquids, total  operating wells
connected and operated miles of pipeline. AGP built two new strategic  pipelines
in  1995 to  facilitate the company's  processing plants on  the Southeast Texas
Pipeline System.  This  investment effectively  doubles  the capacity  of  AGP's
system.
 
    The increased focus on gas and electric trading opportunities is expected to
produce  pre-tax income which ranges between approximately $3.3 million and $6.6
million over  the four-year  period.  In addition,  an investment  in  increased
throughput  capacity for AGP's Texas  intra-state pipeline system is anticipated
to produce pre-tax earnings  which range between $3.9  million and $4.7  million
over the four-year period.
 
NEW PRODUCTS
 
    Both  KCPL  and UCU  are  focusing on  expanding  the relationship  with the
customer by offering  value added  services beyond the  traditional delivery  of
electric  and gas service. UCU's EnergyOne, the first nationally branded line of
products and  services for  the  electric and  gas  utility industry,  seeks  to
provide  a portfolio of value-added services  and customer energy solutions. The
EnergyOne concept and UCU's partnership  with Novell, Inc., a national  provider
of  network software, can be complemented by KCPL's experience in the widespread
deployment  of  the   CellNet  wireless  communication   and  customer   premise
communication technologies.
 
    UCU,  in  cooperation  with  KCPL,  is  currently  developing  an  EnergyOne
partnership program that leverages the  complementary strengths of each  company
and  the national  brand recognition  of EnergyOne.  The financial  strength and
urban presence  of KCPL  coupled  with the  marketing  acumen and  rural  market
coverage  by UCU provides an excellent  foundation for achieving Maxim's goal of
becoming an  energy leader  worldwide. The  partnership will  expand to  include
other energy companies as well as supply partners.
 
    The   combination  of  these  companies   is  expected  to  create  enhanced
opportunities and capabilities to provide customers with energy information  and
communications  services, to better manage operational expenses, and to generate
additional revenues  from new  products  and services.  These new  products  and
services  include  electronic  home  security,  appliance  warranty  service and
leasing of utility fiber optic capacity for telecommunications.
 
    Pre-tax  income  from  new  products  and  services  is  expected  to  total
approximately  $7.0 million to $19.2 million over the four-year period while the
EnergyOne partnership  program  is  expected to  contribute  approximately  $2.3
million  in pre-tax earnings in the first year, growing to $29.6 million by year
four.
 
CORPORATE GROWTH
 
    HISTORICAL --  Both  UCU  and KCPL  have  independently  pursued  strategies
committed  to  continuing  growth  in earnings  and  stockholder  value  in both
regulated and non-regulated business segments.
 
    UCU began its  aggressive growth  in 1983  with the  formation of  UtiliCorp
United  Inc. from its  predecessor company Missouri  Public Service Corporation.
Since 1983 UCU has:
 
                                       57
<PAGE>
    - Acquired  and  merged  with  ten  domestic  electric  and  gas  utilities,
      investing a total of $858 million;
 
    - Purchased  interests in four international electric utilities, investing a
      total of $426 million;
 
    - Established UtilCo Group and invested $206 million in 17 independent power
      projects;
 
    - Established Aquila and invested $303 million in natural gas gathering  and
      transportation assets.
 
    Over the period from 1985 to 1995, UCU has increased its Assets and Earnings
Before   Interest,  Taxes,  Depreciation  and  Amortization  by  431%  and  425%
respectively while also  delivering to  its stockholders a  total return  (stock
appreciation  plus dividends) in excess of both  the average for the S&P 500 and
the utility industry peer group average.*
 
    UCU has also been an industry innovator in marketing and commodity  trading.
In 1995, UCU introduced the first national brand in the electric and gas utility
industry. UCU's brand, EnergyOne, has been nationally recognized and has quickly
achieved a high level of consumer awareness. UCU has built one of the industry's
first  national  sales forces.  Because of  the success  of the  EnergyOne brand
strategy, UCU  now provides  energy solutions  to over  125 of  the Fortune  500
companies in the United States.
 
    UCU  has also been an industry innovator in the application of technology to
the energy industry and to the solution of customer problems. UCU believes  that
its  alliance  with  Novell, Inc.  holds  the  promise of  a  new  generation of
information, comfort  and security  customer solutions.  The two  companies  are
actively working towards product introductions in 1997.
 
    KCPL has also delivered above market and peer-group average total returns to
its  shareholders* as a result of its focus  on economic value added in its core
business and  carefully  planned  growth  through  investment  in  non-regulated
segments.
 
    Over  the past ten years, KCPL  has significantly reduced its financial risk
and increased its financial strength as indicated by its current A1 bond  rating
by  Moody's Investors Service, its A+ bond rating by Duff & Phelps Credit Rating
Company and its A bond rating by Standard & Poor's Corporation. Strong cash flow
and interest  rate  management have  allowed  KCPL  to reduce  debt  and  reduce
interest  rates on existing debt which has resulted in one of the lowest average
costs of debt in the electric utility industry.
 
    KCPL has focused its growth activities principally in non-regulated segments
of the energy
industry. In 1992, KCPL formed KLT,  a non-regulated subsidiary. KLT invests  in
independent  power projects, oil and  gas reserves, utility-related technologies
and services,  and tax-advantaged  investment  opportunities. KLT  has  invested
approximately $150 million since its inception in 1992.
 
MAXIM GROWTH STRATEGY
    The  managements  of  both KCPL  and  UCU  are committed  to  a  strategy of
continuing growth through  investment in  both the  regulated and  non-regulated
segments of the energy business. Overall the goals of the growth strategy are to
provide stockholders:
 
    - total returns above both peer group and broad market averages consistently
      and over an extended period of time;
 
    - an investment which carries below market-average risk (beta); and
 
    - an  investment in a company which has a diversified base of energy-related
      businesses, without undue concentration in (i) fuel source, (ii)  customer
      mix, or (iii) regulatory jurisdiction.

    In  order to achieve these objectives the managements of KCPL and UCU intend
for Maxim  to continue  to  emphasize aggressive  yet carefully  planned  growth
through investment, acquisition and merger.
 
OPINION OF KCPL'S FINANCIAL ADVISOR
    On January 19, 1996, Merrill Lynch delivered its oral opinion, which opinion
was  subsequently confirmed in written opinions dated as of January 19, 1996 and
April 4, 1996, to the KCPL Board to the effect that, as of such dates, and based
upon the assumptions made, matters considered and limits of review, as set forth
in such opinions, the Original KCPL Exchange  Ratio was fair to holders of  KCPL
Common Stock (other than UCU and its affiliates) from a financial point of view.
 
   
    On May 20, 1996, Merrill Lynch delivered its oral opinion, which opinion was
subsequently  confirmed in written opinions  dated as of May  20, 1996 and as of
the date of  this Joint  Proxy Statement/Prospectus, to  the KCPL  Board to  the
effect  that, as  of such  dates and  based upon  the assumptions  made, matters
considered and limits  of review  as set forth  in such  opinions, the  Exchange
Ratio  is  fair  to  holders  of  KCPL Common  Stock  (other  than  UCU  and its
affiliates) from a financial  point of view. References  herein to the  "Merrill
Lynch Opinion" refer to the written opinion of Merrill Lynch dated as of May 20,
1996.  The  Merrill Lynch  opinion  dated as  of the  date  of this  Joint Proxy
Statement/Prospectus is substantially  the same  as the  Merrill Lynch  Opinion,
except  that the Merrill Lynch Opinion indicates that the KCPL Board did not ask
Merrill Lynch to consider the WR Proposal  and Merrill Lynch did not do so,  and
the   Merrill  Lynch  opinion  dated  as  of   the  date  of  this  Joint  Proxy
Statement/Prospectus indicates that the KCPL Board did not ask Merrill Lynch  to
consider  the Proposed Western  Resources Offer as amended  to reflect the terms
contained in the June 17 Announcement and Merrill Lynch did not do so.
    
 
   
    A COPY OF THE MERRILL LYNCH OPINION DATED AS OF THE DATE OF THIS JOINT PROXY
STATEMENT/PROSPECTUS, WHICH SETS FORTH THE ASSUMPTIONS MADE, MATTERS  CONSIDERED
AND  CERTAIN LIMITATIONS ON THE SCOPE OF  REVIEW UNDERTAKEN BY MERRILL LYNCH, IS

    In arriving at the Merrill Lynch  Opinion, Merrill Lynch among other  things
(i) reviewed KCPL's Annual Reports, Forms 10-K and related financial information
for the five fiscal years ended December 31, 1995, and Form 10-Q and the related
unaudited  financial information for the quarterly period ending March 31, 1996;
(ii) reviewed UCU's Annual Reports, Forms 10-K and related financial information
for the five fiscal years ended December 31, 1995, and Form 10-Q and the related
unaudited financial information for the quarterly period ending March 31,  1996;
(iii)  reviewed certain information, including  financial forecasts, relating to
the business,  earnings,  cash flow,  assets  and  prospects of  KCPL  and  UCU,
furnished  to Merrill  Lynch by  KCPL and  UCU; (iv)  conducted discussions with
members of  senior  management  of  KCPL and  UCU  concerning  their  respective
businesses,  regulatory  environments,  prospects and  strategic  objectives and
possible operating, administrative and capital synergies which might be realized
for the combined companies  following the Mergers;  (v) reviewed the  historical
market  prices and trading activity  for KCPL Common Stock  and UCU Common Stock
and compared them  with those  of certain  publicly traded  companies deemed  by
Merrill  Lynch  to be  reasonably similar  to KCPL  and UCU,  respectively; (vi)
compared the  results  of operations  of  KCPL and  UCU  with those  of  certain
companies  deemed by  Merrill Lynch  to be reasonably  similar to  KCPL and UCU,
respectively; (vii) analyzed the relative valuation of KCPL Common Stock and UCU
Common Stock using various valuation methodologies which Merrill Lynch deemed to
be appropriate; (viii) considered the pro  forma effect of the Merger on  KCPL's
capitalization ratios and earnings, dividends and book value per common share of
KCPL Common Stock; (ix) reviewed the
 
                                       59
<PAGE>
Merger  Agreement; and (x)  reviewed such other  financial studies and performed
such other analyses and took into account such other matters deemed necessary by
Merrill Lynch for purposes of rendering the Merrill Lynch Opinion.
 
    In preparing the Merrill Lynch Opinion, Merrill Lynch relied on the accuracy
and completeness of all information supplied  or otherwise made available to  it
by  KCPL  and UCU,  and did  not  independently verify  such information  or any
underlying assumptions. Merrill Lynch did not undertake an independent appraisal
or physical inspection of the assets or liabilities (contingent or otherwise) of
KCPL or UCU. Merrill Lynch also  assumed that the financial forecasts  furnished
to  it by  KCPL and  UCU were  reasonably prepared  in accordance  with accepted
industry practices  and reflected  the best  currently available  estimates  and
judgments of KCPL's and UCU's management, as the case may be, as to the expected
future  financial  performance of  KCPL  and UCU,  respectively,  and as  to the
expected future  projected  outcomes  of various  legal,  regulatory  and  other
contingencies.  Merrill  Lynch also  assumed that  the Mergers  will be  free of
Federal tax to KCPL, UCU,  Sub and the respective  holders of KCPL Common  Stock
and UCU Common Stock, and further assumed that the Mergers will be accounted for
as  a pooling  of interests.  The Merrill  Lynch Opinion  is based  upon general
economic, market, monetary  and other conditions  as they existed  and could  be
evaluated, and the information made available to it, as of May 20, 1996.
 
    KCPL's  management  has advised  Merrill Lynch  that  it believes  there are
significant contingencies and uncertainties associated with the WR Proposal  due
to  the speculative nature  of certain assumptions made  by Western Resources in
the WR Proposal  relating to Western  Resources' ability to  achieve and  retain
certain  estimated aggregate cost  savings, and the  likelihood of substantially
greater rate reductions affecting Western Resources in a pending rate proceeding
than those  assumed by  Western Resources.  KCPL's management  has also  advised
Merrill  Lynch that it  believes the WR  Proposal is not  consistent with KCPL's
strategic objectives. In view of the foregoing, Merrill Lynch has not been asked
by the KCPL  Board to consider,  and Merrill  Lynch has not  considered, the  WR
Proposal in arriving at its opinion.
 
    The  matters considered  by Merrill Lynch  in arriving at  the Merrill Lynch
Opinion are based on numerous macroeconomic, operating and financial assumptions
with respect to industry performance, general business and economic  conditions,
many  of  which  are  beyond  the  control of  KCPL  and  UCU,  and  involve the
application of  complex  methodologies  and  educated  judgment.  Any  estimates
incorporated  in the  analyses performed  by Merrill  Lynch are  not necessarily
indicative  of  actual  past  or  future   results  or  values,  which  may   be
significantly  more or less  favorable than such  estimates. Estimated values do
not purport to be appraisals and do not necessarily reflect the prices at  which
businesses  or companies may  be sold in  the future. The  Merrill Lynch Opinion
does not present a discussion of the  relative merits of the Merger as  compared
to  any other business plan  or opportunity that might  be presented to KCPL, or
the effect of any  other arrangement in which  KCPL might engage. Merrill  Lynch
also  advised  the KCPL  Board  that the  valuation  approaches utilized  in the
relative valuation of  KCPL and  UCU for  purposes of  determining the  Exchange
Ratio  were not intended to  reflect the maximum short-term  value that could be
realized for holders of KCPL Common Stock, including through a sale of KCPL.
 
    The following  is  a  summary  of the  material  financial  and  comparative
analyses performed by Merrill Lynch in arriving at its January 19, 1996 opinion.
 
KCPL VALUATION
    Merrill Lynch performed its valuation of KCPL by separately analyzing KCPL's
two major business segments, the regulated utility business (the "KCPL Regulated
Business")  and the  unregulated businesses (the  "KCPL Unregulated Businesses")
operated  by  KCPL's  unregulated  businesses  subsidiary,  KLT,  Merrill  Lynch
analyzed  the  KCPL Regulated  Business by  performing  an analysis  of publicly
traded comparable companies and a discounted cash flow ("DCF") analysis. Merrill
Lynch analyzed  KLT by  performing a  DCF analysis  of KLT  Investments Inc.,  a
passive  investment portfolio  company ("KLT  Investments"), and  by valuing the
remaining KLT businesses at various multiples of book value.
 
                                       60

    KCPL REGULATED  BUSINESS.   Based upon  the valuation  techniques  described
below,  Merrill Lynch  derived an estimated  enterprise valuation  range for the
KCPL Regulated Business of $2,300 million to $2,475 million.
 
    PUBLICLY TRADED  COMPARABLE  COMPANY  ANALYSIS.   Using  publicly  available
information,  Merrill Lynch compared certain financial and operating information
and  ratios  (described  below)  for  the  KCPL  Regulated  Business  with   the
corresponding  financial and  operating information  and ratios  for a  group of
publicly traded companies that Merrill Lynch deemed to be reasonably similar  to
the  KCPL  Regulated Business.  The companies  included  in the  KCPL comparable
company analysis were: DQE, Inc.,  MidAmerican Energy Company, Oklahoma Gas  and
Electric  Company,  Portland  General Corporation,  Union  Electric  Company and
Western  Resources,   Inc.   (collectively,   the   "KCPL   Regulated   Business
Comparables").  Merrill  Lynch  selected  the companies  in  the  KCPL Regulated
Business Comparables based upon their financial and operating characteristics.
 
    Merrill Lynch derived implied equity values for the KCPL Regulated  Business
by   selecting  certain  multiples  (price  per  share/research  analysts'  1995
estimated earnings per share, price per share/ research analysts' 1996 estimated
earnings per share and  price per share/book value  of common equity per  share)
from  the  KCPL Regulated  Business Comparables  and applying  them to  the KCPL
Regulated Business' projected  1995 earnings,  1996 earnings and  book value  of
common equity for the year ended December 31, 1995. The relevant multiple ranges
for  price per share/research analysts' 1995 estimated earnings per share, price
per share/research analysts'  1996 estimated  earnings per share  and price  per
share/book  value of common equity per share were 12.2x to 14.6x, 12.0x to 14.5x
and 1.4x to  1.9x, respectively.  Merrill Lynch  then added  projected debt  and
preferred stock (less cash) for the KCPL Regulated Business at December 31, 1995
to  arrive at  an estimated  enterprise valuation  range for  the KCPL Regulated
Business.
 
    DISCOUNTED CASH FLOW ANALYSIS.  Merrill  Lynch performed a DCF analysis  for
the  KCPL Regulated Business using KCPL management projections and calculated an
estimated enterprise valuation range. The  DCF was calculated assuming  discount
rates  ranging from 7.75% to 8.75%, and was  comprised of the sum of the present
value of (i) the projected unlevered free cash flows for the years 1996  through
2000,  and (ii) the 2000 terminal value based upon two techniques (a) a range of
multiples from 12.5x  to 13.5x projected  2000 net  income, and (b)  a range  of
multiples  from 1.5x to 1.7x projected 2000 book value of common equity, in each
case adding projected debt and preferred stock (less cash) at year-end 2000.
 
    KCPL UNREGULATED BUSINESSES.  Merrill Lynch performed a DCF analysis for KLT
Investments using  KCPL  management  projections  and  calculated  an  estimated
enterprise  valuation  range. The  DCF  was calculated  assuming  discount rates
ranging from  6.0%  to 7.0%  and  was comprised  of  the present  value  of  the
projected unlevered free cash flows for the years 1996 through 2006, subtracting
projected  non-recourse debt (plus cash) at December 31, 1995. The remaining KLT
entities were valued at 1.0x to 1.5x projected December 31, 1995 book values  as
provided  by  KCPL management.  Based upon  these valuation  techniques, Merrill
Lynch derived an estimated valuation range (after the deduction for non-recourse
debt of KLT which is included  in KCPL's consolidated financial statements)  for
KLT of $95 million to $115 million.
 
UCU VALUATION
    Merrill  Lynch  performed its  valuation analysis  of  UCU by  analyzing the
following  four  business   segments:  regulated   businesses  ("UCU   Regulated
Businesses"),  Aquila,  UtilCo Group  ("UtilCo") and  all other  businesses. For
purposes of its valuation,  contribution and pro  forma analyses, Merrill  Lynch
included  a  December  31,  1995  pro forma  adjustment  to  the  UCU management
projections, furnished  to it  by  UCU management,  of  a delayed  common  stock
offering  of five million UCU shares, which offering is expected to occur in the
third quarter of 1996.
 
    UCU REGULATED BUSINESSES.   The  UCU Regulated Businesses  include all  U.S.
electric  and  gas  utility  operations.  Based  upon  the  valuation techniques
described below, Merrill Lynch derived  an estimated enterprise valuation  range
for the UCU Regulated Businesses of $1,700 million to $1,850 million.
 
                                       61
<PAGE>
    PUBLICLY  TRADED  COMPARABLE  COMPANY ANALYSIS.    Using  publicly available
information, Merrill Lynch compared certain financial and operating  information
and  ratios  (described  below)  for  the  UCU  Regulated  Businesses  with  the
corresponding financial  and operating  information and  ratios for  a group  of
publicly  traded companies that Merrill Lynch deemed to be reasonably similar to
the UCU  Regulated Businesses.  The  companies included  in the  UCU  comparable
company  analysis were: Central Hudson Gas & Electric Corporation, CILCORP Inc.,
Delmarva  Power  &  Light  Company,  LG&E  Energy  Corp.,  Orange  and  Rockland
Utilities, Inc. and Southern Indiana Gas and Electric Company (collectively, the
"UCU Regulated Businesses Comparables"). Merrill Lynch selected the companies in
the  UCU  Regulated  Businesses  Comparables  based  upon  their  financial  and
operating characteristics.
 
    Merrill Lynch derived implied equity values for the UCU Regulated Businesses
by  selecting  certain  multiples  (price  per  share/research  analysts'   1995
estimated  earnings per share, price per share/research analysts' 1996 estimated
earnings per share and  price per share/book value  of common equity per  share)
from  the  UCU Regulated  Businesses Comparables  and applying  them to  the UCU
Regulated Businesses' projected 1995 earnings,  1996 earnings and book value  of
common equity for the year ended December 31, 1995. The relevant multiple ranges
for  price per share/research analysts' 1995 estimated earnings per share, price
per share/research analysts'  1996 estimated  earnings per share  and price  per
share/book  value of common equity per share were 11.5x to 14.4x, 11.3x to 13.6x
and 1.2x to  1.7x, respectively.  Merrill Lynch  then added  projected debt  and
preferred  stock (less  cash) for the  UCU Regulated Businesses  at December 31,
1995 to arrive at an estimated enterprise valuation range for the UCU  Regulated
Businesses.
 
    DISCOUNTED  CASH FLOW ANALYSIS.  Merrill  Lynch performed a DCF analysis for
the UCU Regulated Businesses using UCU management projections and calculated  an
estimated  enterprise valuation range. The  DCF was calculated assuming discount
rates ranging from 7.5%  to 8.5%, and  was comprised of the  sum of the  present
value  of (i) the projected unlevered free cash flows for the years 1996 through
2000, and (ii) the 2000 terminal value based upon two techniques (a) a range  of
multiples  from 13.0x  to 14.0x projected  2000 net  income, and (b)  a range of
multiples from 1.5x to 1.7x projected 2000 book value of common equity, in  each
case adding projected debt and preferred stock (less cash) at year-end 2000.
 
    AQUILA  ENERGY  CORPORATION.   Merrill Lynch  performed a  segment valuation
analysis of Aquila that involved the  individual analysis of AGP, Aquila  Energy
Marketing  ("AEM") and  Aquila Power Corporation  ("Aquila Power").  For AGP and
AEM, Merrill  Lynch  utilized  three valuation  methodologies:  publicly  traded
comparable  company analysis,  comparable company  acquisition analysis  and DCF
analysis. For Aquila Power, Merrill Lynch performed a DCF analysis.
 
    Based upon the valuation techniques  described below, Merrill Lynch  derived
an  estimated enterprise valuation range for  Aquila after adjusting for certain
unallocated corporate amounts and before deducting minority interest related  to
AGP, of $585 million to $675 million.
 
    PUBLICLY  TRADED  COMPARABLE  COMPANY ANALYSIS.    Using  publicly available
information, Merrill Lynch compared certain financial and operating  information
and  ratios (described below) for AGP  and AEM, with the corresponding financial
and operating information and  ratios for a group  of publicly traded  companies
that  Merrill Lynch  deemed to be  reasonably similar  to both AGP  and AEM. The
companies  included  in  the  Aquila  comparable  company  analysis  were:   NGC
Corporation,  Tejas  Gas Corporation,  Tejas Power  Corporation and  Western Gas
Resources, Inc. (collectively, the "Aquila Comparables"). Merrill Lynch selected
the companies in the Aquila Comparables based upon their financial and operating
characteristics.
 
    In the case of AGP, which is publicly traded on the New York Stock Exchange,
Merrill Lynch compared the market value of AGP Common Stock as a multiple of (a)
estimated 1995 EPS (the "1995 EPS Multiple"), which estimates were obtained from
Institutional Brokers Estimating  Service ("IBES")  and (b)  estimated 1996  EPS
(the  "1996  EPS Multiple"),  which  estimates were  obtained  from IBES  to the
corresponding ratios  for the  Aquila Comparables.  Additionally, Merrill  Lynch
compared  the market capitalization of  AGP as a multiple  of (a) 1995 projected
EBITDA (the "1995 EBITDA Multiple"), (b) 1996 projected EBITDA (the "1996 EBITDA
Multiple"), (c) 1995 projected
 
                                       62
<PAGE>
EBIT (the  "1995  EBIT Multiple"),  (d)  1996  projected EBIT  (the  "1996  EBIT
Multiple")  and (e) 1995  projected total assets (the  "1995 Asset Multiple") to
the corresponding ratios for  the Aquila Comparables.  Merrill Lynch derived  an
estimated  enterprise valuation range for AGP by applying these multiples to the
comparable AGP values. In  the case of  the 1995 EPS Multiple  and the 1996  EPS
Multiple,  Merrill Lynch added projected debt (less cash) to arrive at estimated
enterprise values  for  AGP. The  relevant  multiple  ranges for  the  1995  EPS
Multiple,  the  1996 EPS  Multiple, the  1995 EBITDA  Multiple, the  1996 EBITDA
Multiple, the 1995  EBIT Multiple,  the 1996 EBIT  Multiple and  the 1995  Asset
Multiple  were 21.0x to 22.3x, 14.4x to 16.1x, 7.9x to 9.4x, 6.9x to 8.3x, 13.3x
to 13.9x, 10.3x to 12.5x and 0.9x  to 1.3x, respectively. As used herein,  "EPS"
means  earnings  per  share,  "EBITDA" means  earnings  before  interest, taxes,
depreciation and amortization,  and "EBIT"  means earnings  before interest  and
taxes.
 
    Merrill  Lynch derived an estimated enterprise valuation range for AEM using
both the  market values  of the  Aquila  Comparables as  multiples of  (a)  1995
estimated  EPS, which estimates  were obtained from IBES  and (b) 1996 estimated
EPS, which estimates were obtained from  IBES and the market capitalizations  of
the  Aquila Comparables as multiples  of (a) 1995 projected  EBITDA and (b) 1996
projected EBITDA.  In  the case  of  the 1995  EPS  Multiple and  the  1996  EPS
Multiple,  Merrill Lynch added projected debt (less cash) to arrive at estimated
enterprise values  for  AEM. The  relevant  multiple  ranges for  the  1995  EPS
Multiple,  the 1996 EPS Multiple,  the 1995 EBITDA Multiple  and the 1996 EBITDA
Multiple were 21.0x to  22.3x, 14.4x to  16.1x, 7.9x to 9.4x  and 6.9x to  8.3x,
respectively.
 
    COMPARABLE   COMPANY  ACQUISITION   ANALYSIS.     Using  publicly  available
information, Merrill Lynch reviewed ten transactions announced between July 1993
and August 1995  involving the  acquisition of selected  natural gas  gathering,
processing   and  marketing   companies  (the   "Aquila  Comparable  Acquisition
Transactions") to derive estimated enterprise valuation ranges for both AGP  and
AEM.   The  Aquila  Comparable  Acquisition   Transactions  and  the  date  each
transaction was announced were as  follows: Atlanta Gas Light Company/Sonat  Gas
Marketing Company (August 1995), The Williams Companies, Inc./Gas Company of New
Mexico  (June 1995), El Paso Natural Gas Company/Eastex Energy, Inc. (May 1995),
LG&E  Energy  Corp./Hadson  Corporation  (May  1995),  Associated  Natural   Gas
Corporation/Grand    Valley    Gas    (February    1995),    Panhandle   Eastern
Corporation/Associated   Natural   Gas   Corporation   (December   1994),    NGC
Corporation/Trident  NGL, Inc.  (August 1994),  Red Cedar  Gathering Co./WestGas
Gathering, Inc. (August 1994), KN Energy,  Inc./ American Oil & Gas  Corporation
(March  1994) and Western Gas Resources, Inc./Mountain Gas Resources, Inc. (July
1993).
 
    In the case of AGP, Merrill Lynch  (i) compared the equity value in each  of
the  Aquila Comparable Acquisition  Transactions as a  multiple of then publicly
available (a) latest 12 months ("LTM") net income available to common stock (the
"Net Income Multiple") and (b) book value of common equity for the most recently
available fiscal quarter preceding such transaction (the "Book Value  Multiple")
and  (ii) compared the transaction  value (defined as the  equity value plus the
liquidation value of  preferred stock  plus the  principal amount  of debt  less
cash)  for each of the Aquila  Comparable Acquisition Transactions as a multiple
of then publicly available (a) LTM EBITDA (the "EBITDA Multiple"), (b) LTM  EBIT
(the  "EBIT Multiple") and (c) the total  assets for the most recently available
fiscal quarter preceding such transaction  (the "Asset Multiple"). The  relevant
multiple ranges for the Net Income Multiple, the Book Value Multiple, the EBITDA
Multiple,  the EBIT Multiple and the Asset Multiple were 24.4x to 30.0x, 1.3x to
2.1x, 7.6x to 10.6x, 13.6x to 16.8x and 0.7x to 1.1x, respectively.
 
    In the case of AEM, Merrill Lynch  (i) compared the equity value in each  of
the  Aquila Comparable Acquisition  Transactions as a  multiple of then publicly
available LTM  net  income available  to  common  stock and  (ii)  compared  the
transaction  value for each of the Aquila Comparable Acquisition Transactions as
a multiple of  then publicly  available (a)  LTM EBITDA  and (b)  LTM EBIT.  The
relevant  multiple ranges for  the Net Income Multiple,  the EBITDA Multiple and
the EBIT  Multiple were  24.4x to  30.0x, 7.6x  to 10.6x,  and 13.6x  to  16.8x,
respectively.

    DISCOUNTED  CASH FLOW  ANALYSIS.  Merrill  Lynch performed  DCF analyses for
AGP, AEM  and  Aquila Power  using  UCU management  projections  and  calculated
estimated  enterprise valuation ranges  for each business. For  AGP, the DCF was
calculated assuming discount rates ranging from 7.0% to 12.0%, and was comprised
of the sum of the present value  of (i) the projected unlevered free cash  flows
for  the years 1996 through  2001 and (ii) the 2001  terminal value based upon a
range of multiples from 6.0x to 9.0x  projected EBITDA. For both AEM and  Aquila
Power,  the DCFs  were calculated assuming  discount rates ranging  from 8.0% to
12.0%, and were comprised of the sum  of the present value of (i) the  projected
unlevered  free cash  flows for the  years 1996  through 1999 and  (ii) the 1999
terminal value  based upon  a range  of multiples  from 6.0x  to 9.0x  projected
EBITDA.
 
    UTILCO  GROUP.  Based upon the valuation techniques described below, Merrill
Lynch derived an estimated enterprise valuation range for UtilCo of $165 million
to $200 million.
 
    PUBLICLY TRADED  COMPARABLE  COMPANY  ANALYSIS.   Using  publicly  available
information,  Merrill Lynch compared certain financial and operating information
and ratios (described  below) for  UtilCo with the  corresponding financial  and
operating  information and ratios for a  group of publicly traded companies that
Merrill Lynch  deemed  to be  reasonably  comparable to  UtilCo.  The  companies
included  in the analysis were: The  AES Corporation, California Energy Company,
Inc., Destec  Energy,  Inc.,  Enron  Global  Power  &  Pipelines  L.L.C.,  Ogden
Corporation  and Sithe Energies, Inc.  (collectively, the "UtilCo Comparables").
Merrill Lynch selected the companies in the UtilCo Comparables based upon  their
financial and operating characteristics.
 
    Merrill  Lynch derived an estimated enterprise valuation range for UtilCo by
selecting certain multiples (price  per share/research analysts' 1995  estimated
earnings  per share, price per share/ research analysts' 1996 estimated earnings
per share, price per share/book value  of common equity per share, market  value
of    common   stock/cash    flow,   market    capitalization/revenues,   market
capitalization/EBITDA  and   market   capitalization/EBIT)   from   the   UtilCo
Comparables  and applying  them to  UtilCo's projected  1995 and  1996 earnings,
December 31, 1995 book value of  common equity, 1996 revenues, EBITDA and  EBIT.
In  the case  of price per  share/research analysts' 1995  estimate earnings per
share, price per  share/research analysts'  1996 estimated  earnings per  share,
price per share/book value of common equity per share and market value of common
stock/cash  flow, Merrill Lynch  added projected debt  and preferred stock (less
cash) for UtilCo at December 31,  1995 to arrive at estimated enterprise  values
for  UtilCo. The relevant multiple ranges for price per share/research analysts'
1995 estimated  earnings  per share,  price  per share/research  analysts'  1996
estimated  earnings per share,  price per share/book value  of common equity per
share, market value of  common stock/cash flow, market  capitalization/revenues,
market capitalization/EBITDA and market capitalization/EBIT were 14.1x to 15.6x,
12.2x to 13.3x, 1.0x to 1.8x, 4.2x to 7.7x, 1.0x to 3.9x, 8.2x to 9.8x and 10.5x
to 12.7x, respectively.
 
    DISCOUNTED  CASH FLOW ANALYSIS.  Merrill  Lynch performed a DCF analysis for
UtilCo using UCU's management projections of future project cash flows for  each
of  UtilCo's existing projects in operation or under construction and calculated
an estimated valuation range. The analysis  did not include value for  estimated
earnings  from future development projects that were not under signed or awarded
power contracts. The  DCF was  calculated assuming discount  rates ranging  from
11.5%  to 12.5% and  was comprised of  the sum of  the present value  of (i) the
projected unlevered free cash flows generated by each project over the remaining
term of the project's power purchase agreement and (ii) by assigning a  terminal
value  at the end  of the term of  the power purchase  agreement to each project
based on each project's remaining useful life.
 
    OTHER BUSINESSES.    Other businesses  include  UCU Australia,  UCU  British
Columbia,  UCU  Marketing  Services, UCU  New  Zealand, UCU  United  Kingdom and
Unallocated and Other Items. Using various valuation methodologies, including  a
comparable  company analysis, DCF analysis and book value approaches, similar to
those described above, Merrill Lynch  derived an estimated enterprise  valuation
range for these businesses of $426 million to $577 million.

IMPLIED EXCHANGE RATIO RANGE
    Based upon the estimated valuations of KCPL and UCU set forth above, Merrill
Lynch  derived estimated enterprise and common  equity valuation ranges for both
companies and  calculated an  implied exchange  ratio range  of 0.883  to  1.332
shares of UCU Common Stock to a share of KCPL Common Stock.
 
TRADING RATIO ANALYSIS
    Merrill  Lynch reviewed  the performance of  the per share  market prices of
KCPL Common Stock and UCU Common  Stock over the five-year period ended  January
12,  1996. Merrill  Lynch also calculated  the ratio  of the average  of the per
share market prices of UCU Common Stock  to the per share market prices of  KCPL
Common  Stock from  January 11, 1991  to January  12, 1996, January  15, 1993 to
January 12, 1996, January 20, 1995 to January 12, 1996, July 14, 1995 to January
12, 1996, October 13, 1995 to January 12, 1996 and December 15, 1995 to  January
12,  1996. This analysis  showed that over  the five-year, three-year, one-year,
six-month, three-month and one-month periods, the per share market prices of UCU
Common Stock  compared to  the per  share market  prices of  KCPL Common  Stock,
traded at average ratios of 1.25, 1.26, 1.20, 1.17, 1.13 and 1.11, respectively.
Merrill  Lynch noted for the  KCPL Board that based  on January 12, 1996 closing
prices, the trading ratio of UCU Common Stock compared to KCPL Common Stock  was
1.096.
 
CONTRIBUTION ANALYSIS
    In  order to  determine an  implied exchange  ratio based  upon contribution
analysis, Merrill Lynch calculated the contribution  of KCPL and UCU to the  pro
forma  combined  company with  respect to  (i) earnings  per common  share, (ii)
dividends per common share and (iii) book value of equity per common share,  for
the  years  ended  1993  through  1994  (the  "Historical  Period")  and,  using
management projections (excluding estimated potential synergies) provided by the
respective managements of  KCPL and UCU,  for the years  1995 through 2000  (the
"Projected  Period"). The analysis of earnings  per common share yielded a range
of implied exchange ratios for UCU Common Stock to KCPL Common Stock of 1.273 to
1.299 during  the Historical  Period and  0.980 to  1.163 during  the  Projected
Period.  The analysis of dividends  per common share yielded  a range of implied
exchange ratios of  1.109 to  1.132 during the  Historical Period  and 1.081  to
1.114  during the Projected Period. The analysis  of book value of common equity
per common share yielded a  range of implied exchange  ratios of 1.439 to  1.449
during the Historical Period and 1.406 to 1.461 during the Projected Period.
 
PRO FORMA ANALYSIS
    Merrill  Lynch also  analyzed certain pro  forma effects  resulting from the
Original Merger, including the potential impact to KCPL's projected  stand-alone
earnings  per share, dividends per share,  dividend payout ratios and total debt
to total capitalization ratios. Using the projected earnings for the years  1995
through  2000 provided  by the respective  managements of KCPL  and UCU, Merrill
Lynch compared the projected earnings per  share of KCPL on a stand-alone  basis
(assuming  the Original  Merger does  not occur)  to the  earnings per  share of
common stock of KCU  assuming the exchange ratios  contemplated by the  Original
Merger  Agreement.  In  addition,  Merrill  Lynch  considered  certain estimated
synergies expected  to be  achieved as  a  result of  the Original  Merger.  For
conservatism,  Merrill Lynch  excluded certain  savings in  the area  of capital
deferral. For its  pro forma analysis,  based upon input  from KCPL  management,
Merrill Lynch assumed 50% of the estimated pre-tax labor and non-labor synergies
would be realized by stockholders of Maxim.
 
    Assuming  inclusion  of  the  synergies  as  detailed  above,  the  analysis
indicated that the Original Merger would  be dilutive to the projected  earnings
per  share of a KCPL shareholder in the amount of 3.4% in 1995, accretive to the
projected earnings per  share of a  KCPL shareholder  in the amount  of 0.6%  in
1996,  dilutive to the projected earnings per share of a KCPL shareholder in the
amount of 0.6% in 1997  and accretive to the projected  earnings per share of  a
KCPL  shareholder in the amounts of 0.8% in 1998, 2.1% in 1999 and 4.9% in 2000.
KCPL's stand-alone dividend payout  ratios were projected to  be 81.7% in  1995,
81.5%  in 1996, 75.5%  in 1997, 70.2% in  1998, 67.6% in 1999  and 67.5% in 2000
compared to KCU's projected  dividend payout ratios of  86.9% in 1995, 81.1%  in
1996,  76.0% in  1997, 69.9% in  1998, 66.2% in  1999 and 64.3%  in 2000. KCPL's
stand-alone total debt to total
 
                                       65
<PAGE>
capitalization ratios were projected to be  44.5% in 1996, 44.4% in 1997,  42.7%
in  1998, 41.6% in  1999 and 40.7%  in 2000 compared  to Maxim's projected total
debt to total capitalization ratios  of 51.2% in 1996,  50.7% in 1997, 48.8%  in
1998, 46.8% in 1999 and 46.2% in 2000.
 
    In  addition, Merrill Lynch made a  similar comparison assuming the exchange
ratios contemplated  by the  Original Merger  Agreement with  no synergies.  The
analysis  indicated that the Original Merger  would be dilutive to the projected
earnings per share of  a KCPL shareholder  in amounts of 3.4%  in 1995, 1.4%  in
1996,  4.6% in 1997, 4.6% in 1998, 3.9%  in 1999 and 1.8% in 2000. KCPL's stand-
alone dividend payout ratio was  projected to be 81.7%  in 1995, 81.5% in  1996,
75.5%  in 1997, 70.2% in 1998, 67.6% in 1999 and 67.5% in 2000 compared to KCU's
projected dividend payout ratio of 86.9% in 1995, 82.7% in 1996, 79.2% in  1997,
73.5% in 1998, 70.3% in 1999 and 68.7% in 2000. KCPL's stand-alone total debt to
total  capitalization ratio was  projected to be  44.5% in 1996,  44.4% in 1997,
42.7% in 1998, 41.6% in 1999 and 40.7% in 2000 compared to KCU's projected total
debt to total capitalization  ratio of 51.2%  in 1996, 51.1%  in 1997, 49.4%  in
1998,  47.7% in 1999 and 47.6% in  2000. In both analyses, Merrill Lynch assumed
that KCU would assume the same dividend policy as KCPL.
 
    The following  is  a  summary  of the  material  financial  and  comparative
analyses  performed by Merrill Lynch in  connection with its presentation to the
KCPL Board on May 20, 1996 and used by Merrill Lynch in arriving at the  Merrill
Lynch Opinion.
 
RELATIVE STOCK PRICE PERFORMANCE
 
    Merrill  Lynch reviewed  the performance of  the per share  market prices of
KCPL Common Stock and UCU Common  Stock over the five-year and one-year  periods
ended  May 17, 1996. Merrill Lynch compared  the per share market prices of KCPL
Common Stock and UCU Common Stock versus the S&P Electric Companies Index and an
index of  regional companies  which included  IES Industries  Inc.,  MidAmerican
Energy  Company, Oklahoma Gas  and Electric Company,  Union Electric Company and
Western Resources, Inc.
 
TRADING RATIO ANALYSIS
 
    Merrill Lynch calculated the  ratio of the average  of the per share  market
prices  of UCU Common Stock to the per  share market prices of KCPL Common Stock
from May 17, 1991 to May 17, 1996, May 14, 1993 to May 17, 1996, May 19, 1995 to
May 17, 1996, November 17,  1995 to May 17, 1996,  February 16, 1996 to May  17,
1996  and April  12, 1996 to  May 17, 1996.  This analysis showed  that over the
five-year, three-year, one-year, six-month,  three-month and one-month  periods,
the  per share  market prices  of UCU  Common Stock,  compared to  the per share
market prices of  KCPL Common  Stock, traded at  average ratios  of 1.24,  1.25,
1.16, 1.12, 1.12, and 1.09, respectively.
 
PRO FORMA ANALYSIS -- EXCLUDING REVENUE ENHANCEMENTS
 
    Merrill  Lynch analyzed certain pro forma effects resulting from the Mergers
excluding  certain  revenue   enhancements,  or   unregulated  business   growth
opportunities,  as provided  by the  managements of  KCPL and  UCU, as described
below. Merrill Lynch  analyzed the  potential impact  of the  Mergers on  KCPL's
projected  stand-alone  earnings per  share,  dividends per  share  and dividend
payout ratios,  using  both  management projections  and  First  Call  consensus
earnings  estimates and management projections for  dividends per share. In both
analyses, Merrill Lynch compared the projected earnings per share, dividends per
share and dividend payout ratios  of KCPL for the years  1996 through 2000 on  a
stand-alone basis (assuming the Mergers do not occur) to the earnings per share,
dividends  per share and dividend payout  ratios of Maxim Common Stock (assuming
the Effective Time  of the  Mergers is January  1, 1997)  assuming the  Exchange
Ratio   contemplated  by  the  Merger  Agreement.  In  addition,  Merrill  Lynch
considered the  financial  effects  of certain  estimated  synergies  (including
amounts,  timing  of  realization  and retention  rates  to  Maxim shareholders)
expected to be achieved as a result of the Mergers as provided by Ernst &  Young
and  included in KCPL's and UCU's filing  with the FERC relating to the Original
Merger. Merrill Lynch did not consider  the financial effects of the  additional
operational   benefits  discussed  above  under  the  caption  "THE  MERGERS  --
Additional Operational Benefits."
 
    Using the projected earnings for the years 1996 through 2000 provided by the
respective managements of KCPL and UCU, the analysis indicated that the  Mergers
would be accretive to the projected
 
                                       66
<PAGE>
earnings per share of a KCPL shareholder in the amounts of 3.8% in 1996, 1.5% in
1997, 3.3% in 1998, 7.0% in 1999 and 10.2% in 2000. Assuming Maxim dividends per
share  of $1.85 in  1997, $1.90 in  1998, $1.95 in  1999 and $2.00  in 2000, the
analysis indicated  that  the  Mergers  would  be  accretive  to  the  projected
dividends per share of a KCPL shareholder in the amounts of 15.6% in 1997, 15.9%
in  1998, 16.1% in  1999 and 16.3%  in 2000. KCPL's  stand-alone dividend payout
ratios were projected  to be 74.4%  in 1997, 69.2%  in 1998, 66.7%  in 1999  and
66.9%  in 2000 compared to  Maxim's projected dividend payout  ratio of 84.8% in
1997, 77.6% in 1998, 72.4% in 1999 and 70.6% in 2000.
 
    Using the projected earnings  for the years 1996  through 2000 derived  from
First Call consensus earnings estimates, the analysis indicated that the Mergers
would  be accretive to the projected earnings per share of a KCPL shareholder in
the amounts of  4.7% in 1996,  5.7% in 1997,  10.4% in 1998,  14.8% in 1999  and
18.1%  in 2000. Assuming  Maxim dividends per  share of $1.85  in 1997, $1.90 in
1998, $1.95 in 1999 and $2.00 in  2000, the analysis indicated that the  Mergers
would be accretive to the projected dividends per share of a KCPL shareholder in
the  amounts of 15.6% in 1997,  15.9% in 1998, 16.1% in  1999 and 16.3% in 2000.
KCPL's stand-alone dividend payout  ratios were projected to  be 77.7% in  1997,
77.8%  in 1998, 78.0%  in 1999 and  78.0% in 2000  compared to Maxim's projected
dividend payout ratio of 84.9% in 1997,  81.7% in 1998, 78.8% in 1999 and  76.8%
in 2000.
 
PRO FORMA ANALYSIS -- INCLUDING REVENUE ENHANCEMENTS
 
    In  addition, Merrill Lynch separately analyzed certain pro forma effects of
the  Mergers  including  certain  revenue  enhancements,  as  provided  by   the
management  teams from both KCPL  and UCU. CLC assisted  the managements of KCPL
and UCU in their  identification of these  revenue enhancements by  facilitating
discussions  between KCPL and UCU and by reviewing the methodologies utilized in
the identification  of  these  revenue enhancements.  Merrill  Lynch's  analysis
consisted of a revenue enhancement sensitivity assuming $30, $45 and $60 million
of  pre-tax revenue  enhancements per  year. Merrill  Lynch assumed  that 50% of
these pre-tax revenue enhancements would be realized in 1997, and 100% of  these
pre-tax revenue enhancements would be realized thereafter.
 
    Using the projected earnings for the years 1997 through 2000 provided by the
respective  managements  of KCPL  and UCU  and assuming  $30 million  of pre-tax
revenue enhancements per year, the analysis indicated that the Mergers would  be
accretive  to the  projected earnings  per share  of a  KCPL shareholder  in the
amounts of 5.3% in 1997, 10.3% in 1998, 13.5% in 1999 and 16.7% in 2000.  KCPL's
stand-alone  dividend payout ratios were projected to be 74.4% in 1997, 69.2% in
1998, 66.7% in  1999 and 66.9%  in 2000 compared  to Maxim's projected  dividend
payout  ratio of 81.7% in 1997, 72.7% in  1998, 68.2% in 1999 and 66.7% in 2000.
Assuming $45  million of  pre-tax revenue  enhancements per  year, the  analysis
indicated  that the  Mergers would  be accretive  to the  projected earnings per
share of a KCPL shareholder in the amounts of 7.3% in 1997, 13.8% in 1998, 16.8%
in 1999  and 19.9%  in  2000. KCPL's  stand-alone  dividend payout  ratios  were
projected  to be 74.4% in 1997,  69.2% in 1998, 66.7% in  1999 and 66.9% in 2000
compared to Maxim's projected dividend payout  ratio of 80.2% in 1997, 70.4%  in
1998,  66.2% in 1999 and 64.9% in  2000. Assuming $60 million of pre-tax revenue
enhancements per  year,  the  analysis  indicated  that  the  Mergers  would  be
accretive  to the  projected earnings  per share  of a  KCPL shareholder  in the
amounts of 9.2% in 1997, 17.4% in 1998, 20.1% in 1999 and 23.2% in 2000.  KCPL's
stand-alone  dividend payout ratios were projected to be 74.4% in 1997, 69.2% in
1998, 66.7% in  1999 and 66.9%  in 2000 compared  to Maxim's projected  dividend
payout ratio of 78.8% in 1997, 68.3% in 1998, 64.4% in 1999 and 63.2% in 2000.
 
    Using  the projected earnings  for the years 1997  through 2000 derived from
First Call  consensus earnings  estimates and  assuming $30  million of  pre-tax
revenue  enhancements per year, the analysis indicated that the Mergers would be
accretive to  the projected  earnings per  share of  a KCPL  shareholder in  the
amounts  of 9.8% in 1997, 18.3% in 1998, 22.5% in 1999 and 25.6% in 2000. KCPL's
stand-alone dividend payout ratios were projected to be 77.7% in 1997, 77.8%  in
1998,  78.0% in 1999  and 78.0% in  2000 compared to  Maxim's projected dividend
payout ratio of 81.8% in 1997, 76.2% in  1998, 73.9% in 1999 and 72.2% in  2000.
Assuming  $45 million  of pre-tax  revenue enhancements  per year,  the analysis
indicated that the  Mergers would  be accretive  to the  projected earnings  per
share  of a  KCPL shareholder in  the amounts of  11.8% in 1997,  22.3% in 1998,
26.3% in 1999 and 29.4% in 2000. KCPL's stand-alone dividend payout ratios  were
projected to be 77.7% in 1997, 77.8% in 1998, 78.0%
 
                                       67

in 1999 and 78.0% in 2000 compared to Maxim's projected dividend payout ratio of
80.3%  in 1997,  73.8% in 1998,  71.6% in 1999  and 70.1% in  2000. Assuming $60
million of pre-tax revenue  enhancements per year,  the analysis indicated  that
the  Mergers would be  accretive to the  projected earnings per  share of a KCPL
shareholder in the amounts of  13.8% in 1997, 26.2% in  1998, 30.2% in 1999  and
33.1%  in 2000. KCPL's  stand-alone dividend payout ratios  were projected to be
77.7% in  1997, 77.8%  in 1998,  78.0% in  1999 and  78.0% in  2000 compared  to
Maxim's  projected dividend payout ratio of 78.9%  in 1997, 71.5% in 1998, 69.5%
in 1999 and 68.2% in 2000.
 
    The summary set forth above does not purport to be a complete description of
the analyses performed by Merrill Lynch in arriving at the Merrill Lynch Opinion
or the  written opinion  dated as  of January  19, 1996.  The preparation  of  a
fairness  opinion is a complex process not necessarily susceptible to partial or
summary description. Merrill Lynch believes that its analyses must be considered
as a  whole and  that selecting  portions of  its analyses  and of  the  factors
considered  by  it, without  considering all  such  factors and  analyses, could
create a misleading view of the process underlying its analyses set forth in the
Merrill Lynch Opinion and its opinion dated  as of January 19, 1996. No  company
in  the  KCPL  Regulated  Business  Comparables,  the  UCU  Regulated Businesses
Comparables, the Aquila Comparables  or the UtilCo  Comparables is identical  to
the  KCPL  Regulated Business,  the UCU  Regulated Businesses,  AGP and  AEM, or
UtilCo, respectively.  Accordingly, an  analysis of  publicly traded  comparable
companies  is not mathematical;  rather, it involves  complex considerations and
judgments concerning differences in  financial and operating characteristics  of
the  comparable companies and other factors that could affect the public trading
value of the comparable companies or company to which they are being compared.
 
    The KCPL Board selected Merrill Lynch  to render a fairness opinion  because
Merrill  Lynch  is an  internationally recognized  investment banking  firm with
substantial experience in transactions similar to  the Merger and because it  is
familiar  with  KCPL and  its  business. Merrill  Lynch  has from  time  to time
rendered investment banking, financial advisory  and other services to KCPL  for
which  it has received customary compensation. As part of its investment banking
business, Merrill Lynch is  continually engaged in  the valuation of  businesses
and their securities in connection with mergers and acquisitions.
 
    Pursuant  to the terms of an engagement letter dated November 14, 1995, KCPL
has agreed  to  pay  Merrill Lynch  (i)  a  $150,000 retainer  fee  and  (ii)  a
transaction  fee equal to  $7,000,000 (the "Transaction  Fee") against which the
amount referred  to in  clause (i)  will  be credited.  The Transaction  Fee  is
payable  in three installments  (a) 33 1/3%  upon the execution  of a definitive
agreement to effect the  Merger, (b) 33 1/3%  upon shareholder approval and  (c)
any remaining unpaid portion upon closing of the Merger. KCPL has also agreed to
reimburse  Merrill Lynch for  its reasonable out-of-pocket  expenses, subject to
certain limitations, and to indemnify Merrill Lynch and certain related  persons
against certain liabilities in connection with its engagement, including certain
liabilities under the federal securities laws.
 
    Pursuant  to the terms of an engagement letter dated March 4, 1995, KCPL has
retained Merrill  Lynch  as its  exclusive  financial advisor  with  respect  to
certain  events, including, among other things,  (a) any acquisition by a person
or group of persons of 5% or more of any class of KCPL's equity securities,  (b)
any solicitation of proxies or shareholder consents in opposition to, or without
the  support of the KCPL Board, (c) any  oral or written proposal to KCPL or any
of its shareholders  relating to an  acquisition of, or  a business  combination
involving  KCPL  (by  merger, tender  offer  or  otherwise) or  relating  to the
acquisition of any of its capital stock  or all or a substantial portion of  its
revenues  or  income by  way  of a  joint  venture, negotiated  purchase, lease,
license, exchange or  other means  or (d) any  other extraordinary  transactions
involving  KCPL. Pursuant to  such engagement letter, KCPL  has agreed to retain
Merrill  Lynch  on  terms  and  conditions  customarily  established  by   major
investment  banking firms for similar services  in similar circumstances at such
time. KCPL  has  also agreed  to  reimburse  Merrill Lynch  for  its  reasonable
out-of-pocket  expenses  and  to  indemnify Merrill  Lynch  and  certain related
persons against certain liabilities in connection with its engagement, including
certain liabilities under the federal securities laws.

    In the  ordinary  course of  Merrill  Lynch's business,  Merrill  Lynch  may
actively  trade the securities of  KCPL and UCU for its  own account and for the
accounts of its customers and, accordingly, may at any time hold a long or short
position in such securities.
 
OPINION OF UCU'S FINANCIAL ADVISOR
 
    UCU has engaged DLJ to act as  its financial advisor in connection with  the
transactions  contemplated by the Merger Agreement  and to render its opinion to
the UCU  Board as  to the  fairness,  from a  financial point  of view,  to  the
stockholders  of UCU of the  terms of the Exchange  Ratio pursuant to the Merger
Agreement. DLJ was retained based on its experience, expertise in the  industry,
reputation and prior relationship with UCU.
 
    On  May 19,  1996, DLJ delivered  its oral  opinion to the  UCU Board, which
opinion was subsequently confirmed in a written opinion dated as of May 19, 1996
and  a  further   written  opinion   dated  the   date  of   this  Joint   Proxy
Statement/Prospectus,  to the effect that,  as of such dates  and subject to the
assumptions made, matters considered and limits of the review undertaken, as set
forth in such opinions, the  Exchange Ratio is fair,  from a financial point  of
view,  to holders  of UCU  Common Stock. Reference  herein to  the "DLJ Opinion"
refers to the written opinion of DLJ dated  as of May 19, 1996. The DLJ  Opinion
dated  the date  of this Joint  Proxy Statement/Prospectus  is substantially the
same as the May 19, 1996 opinion.
 
    A COPY OF THE  WRITTEN OPINION OF DLJ,  DATED AS OF THE  DATE OF THIS  JOINT
PROXY   STATEMENT/PROSPECTUS,  WHICH   SETS  FORTH   ASSUMPTIONS  MADE,  MATTERS
CONSIDERED AND LIMITS  OF THE REVIEW  UNDERTAKEN BY DLJ,  IS ATTACHED HERETO  AS
ANNEX  C AND IS INCORPORATED HEREIN BY  REFERENCE. STOCKHOLDERS OF UCU ARE URGED
TO, AND SHOULD, READ SUCH OPINION IN  ITS ENTIRETY. THE DLJ OPINION IS  DIRECTED
ONLY TO THE FAIRNESS OF THE UCU EXCHANGE RATIO FROM A FINANCIAL POINT OF VIEW TO
HOLDERS  OF UCU COMMON STOCK AND DOES NOT CONSTITUTE A RECOMMENDATION TO ANY UCU
STOCKHOLDER AS  TO HOW  SUCH STOCKHOLDER  SHOULD VOTE  AT THE  UCU MEETING.  THE
SUMMARY  OF THE DLJ OPINION SET  FORTH IN THIS JOINT PROXY STATEMENT/PROSPECTUS,
WHILE CONTAINING ALL  MATERIAL ELEMENTS  OF SUCH  OPINION, IS  QUALIFIED IN  ITS
ENTIRETY  BY REFERENCE TO THE FULL  TEXT OF THE OPINION OF  DLJ, DATED AS OF THE
DATE OF THIS JOINT PROXY STATEMENT/PROSPECTUS, ATTACHED AS ANNEX C HERETO.
 
    In arriving at the  DLJ Opinion, DLJ reviewed,  among other things, (i)  the
draft  Merger Agreement, dated May 18, 1996; (ii) Annual Reports to Stockholders
and Annual Reports on Form 10-K of UCU and KCPL for the five fiscal years  ended
December  31, 1995 and  Quarterly Reports on Form  10-Q of UCU  and KCPL for the
periods ending June 30, 1995, September 30, 1995 and March 31, 1996; (iii)  FERC
Forms  1 of UCU and KCPL; (iv) certain other communications from UCU and KCPL to
their respective  stockholders;  (v)  certain internal  financial  analyses  and
projections,   including   analyses   and  projections   of   certain  operating
efficiencies and financial synergies expected to be achieved as a result of  the
Mergers, provided to DLJ by each of UCU and KCPL; (vi) the historical prices and
trading  volumes of  the common stock  of each  of UCU and  KCPL; (vii) publicly
available financial data and  stock market performance  data of companies  which
DLJ  deemed comparable  in relevant  respects to  UCU and  KCPL; and  (viii) the
financial terms, including prices and premiums paid, of certain recent  business
combinations in the gas and electric utility industry. DLJ also held discussions
with  members of the  senior management of  UCU and KCPL  regarding the past and
current business operations, financial condition  and future prospects of  their
respective  companies and their  analyses of strategic  benefits of the Mergers,
including, without  limitation, the  amount  and timing  of realization  of  the
synergies  referred to  above. In addition,  DLJ performed  such other financial
studies, analyses and investigations, and  took into account such other  matters
as DLJ considered appropriate for purposes of rendering the DLJ Opinion.
 
    In  connection with its review, DLJ did  not independently verify any of the
foregoing information or any underlying assumptions, including certain synergies
expected to be achieved in the Mergers, and relied on the accuracy, completeness
and fairness of all  financial and other information  that was available to  DLJ
from  public sources, that was provided to  DLJ by UCU, KCPL or their respective
representatives, or that was otherwise  reviewed by DLJ, including the  outcomes
projected  by UCU  and KCPL of  legal, regulatory and  other contingencies. With
respect to the financial projections supplied to DLJ, DLJ assumed that they  had
been    reasonably    prepared    on    the    basis    reflecting    the   best
 
                                       69
<PAGE>
currently available estimates and judgment of the managements of UCU and KCPL as
to the future financial performance of UCU and KCPL, as the case may be, and  as
to  the outcomes projected of legal, regulatory and other contingencies. DLJ did
not and does not  assume any responsibility for  the information or  projections
provided  to  it,  and  DLJ  has  further  relied  upon  the  assurances  of the
managements of UCU and KCPL that they  are unaware of any facts that would  make
the  information or  projections provided  to DLJ  incomplete or  misleading. In
addition, DLJ, with UCU's  consent, did not make  an independent evaluation  and
appraisal  of  the assets  and  liabilities of  UCU  or KCPL  or  any respective
subsidiaries and  DLJ  has  not  been furnished  with  any  such  evaluation  or
appraisal. In arriving at its opinion, DLJ assumed, with UCU's consent, that the
consummation  of the transactions  contemplated by the  Merger Agreement will be
accounted for  as a  pooling of  interests under  generally accepted  accounting
principles.  In addition, DLJ assumed that  the Mergers will be a reorganization
as described in Section 368(a) of the Code, and the regulations thereunder,  and
that  UCU and the stockholders of UCU who exchange their shares solely for stock
of Maxim will recognize  no gain or  loss for federal income  tax purposes as  a
result  of the consummation of the Mergers. The DLJ Opinion is necessarily based
on economic, market and other conditions, and the information made available  to
it, as of May 19, 1996.
 
    In rendering the DLJ Opinion, DLJ performed a variety of financial analyses.
All such material analyses are summarized below.
 
    COMPARABLE  PUBLIC COMPANIES.   DLJ  reviewed and  compared certain publicly
available historical  financial  information,  projected  1996,  1997  and  1998
financial  results (based on  research analysts' estimates  as reported by IBES)
and stock market performance for UCU  and KCPL to corresponding information  for
selected  publicly-traded companies including  Cilcorp, Inc., Citizens Utilities
Company, MidAmerican  Energy  Company, MDU  Resources  Group, Inc.  and  Western
Resources, Inc. (collectively, the "Public Comparables"). The Public Comparables
were  chosen because they are publicly-traded companies with operations that for
purposes of analysis may be considered similar to UCU and KCPL.
 
    DLJ examined, among other  things, (i) the  market capitalization; (ii)  the
per share market price as a multiple of (a) EPS for the latest twelve months for
which financial reports had been filed with the SEC; (b) 1996 projected EPS (the
"1996  PE  Ratio"); (c)  1997  projected EPS  (the  "1997 PE  Ratio");  (d) 1998
projected EPS (the  "1998 PE  Ratio") and  (e) per  share book  value of  common
equity  (the "Price/Book  Ratio") for the  most recent fiscal  quarter for which
financial information was available and  (iii) the enterprise value (defined  as
market capitalization plus the principal amount of debt and liquidation value of
preferred  stock  less cash  and  cash equivalents)  as  a multiple  of  (a) LTM
revenue; (b)  LTM  EBITDA;  and  (c)  LTM EBIT  of  UCU,  KCPL  and  the  Public
Comparables.  Although  DLJ  considered  each of  the  foregoing  multiples, DLJ
attributed relatively greater weight to the  1996 PE Ratio, 1997 PE Ratio,  1998
PE  Ratio and the  Price/Book Ratio for  purposes of its  analyses of the Public
Comparables.
 
    The analysis indicated that the  average (excluding the maximum and  minimum
values)  1996 PE Ratio, 1997 PE Ratio, 1998 PE Ratio and Price/Book Ratio of the
Public Comparables was 13.0x, 12.4x, 11.9x and 1.4x, respectively. The  analysis
also  indicated  that UCU's  1996 PE  Ratio, 1997  PE Ratio,  1998 PE  Ratio and
Price/Book Ratio were  12.8x, 12.3x,  11.7x and 1.3x,  respectively, and  KCPL's
1996  PE Ratio, 1997  PE Ratio, 1998  PE Ratio and  Price/Book Ratio were 13.4x,
12.9x, 12.5x  and  1.8x, respectively.  Such  multiples, except  the  Price/Book
Ratio,  were based  on a  composite of  research analyst  estimates of projected
1996, 1997 and 1998 EPS  as reported by IBES.  The comparison of trading  levels
for UCU Common Stock and KCPL Common Stock to the average trading levels for the
Public Comparables provided an indication that neither UCU Common Stock nor KCPL
Common  Stock  were  trading  at levels  materially  different  than  the Public
Comparables.
 
    COMPARABLE  MERGER  &  ACQUISITION  TRANSACTION  ANALYSIS.    DLJ   reviewed
comparable  transactions  involving  proposed or  completed  mergers  between or
acquisitions of regulated gas and electric utilities occurring between June 1994
and November 1995 (the "Comparable M&A Transactions"). The companies involved in
the  Comparable  M&A   Transactions  were  IES   Industries,  Interstate   Power
 
                                       70
<PAGE>
and  WPL  Holdings; Washington  Energy Company  and Puget  Sound Power  & Light;
Potomac Electric  Power Company  and Baltimore  Gas and  Electric;  Southwestern
Public  Service and Public  Service Co. of Colorado;  Pennsylvania Power & Light
and PECO Energy; CIPSCO and Union Electric; Northern States Power and  Wisconsin
Energy  Corp.; Iowa-Illinois Gas & Electric  Company and Midwest Resources Inc.;
and Sierra Pacific Resources and Washington Water Power Co. DLJ studied  certain
publicly  available data for  each of the  Comparable M&A Transactions including
the market value of the consideration to be received by the stockholders of  the
company  (the "Equity Consideration")  as a multiple  of the LTM  net income and
book value. In addition,  DLJ calculated the  "Total Consideration" (defined  as
Equity Consideration plus the principal amount of debt and the liquidation value
of  preferred stock minus  cash and cash  equivalents and option  proceeds) as a
multiple of LTM revenue, LTM EBITDA and LTM EBIT.
 
    The  analysis  of  Comparable   M&A  Transactions  yielded  average   Equity
Consideration  multiples of  LTM net  income and book  value of  14.8x and 1.6x,
respectively, and Total Consideration multiples  of LTM revenue, LTM EBITDA  and
LTM EBIT of 2.2x, 7.4x and 11.3x, respectively. Based on the Exchange Ratio, DLJ
calculated  per share  Equity Consideration multiples  of LTM EPS  and per share
book value  of  common  equity  of  12.0x  and  1.3x,  respectively,  and  Total
Consideration  multiples of LTM revenue,  LTM EBITDA and LTM  EBIT of 0.9x, 6.6x
and 10.2x, respectively, for UCU and per share Equity Consideration multiples of
LTM EPS  and  per  share  book  value  of  common  equity  of  14.0x  and  1.9x,
respectively,  and Total Consideration multiples of  LTM revenue, LTM EBITDA and
LTM EBIT of 3.0x, 7.5x and 11.2x, respectively, for KCPL.
 
    Because the reasons for and circumstances surrounding each of the Comparable
M&A Transactions analyzed were diverse  and because of the inherent  differences
between  the operations of UCU, KCPL and the companies engaged in the Comparable
M&A Transactions, DLJ believed that a purely quantitative comparable transaction
analysis would not be particularly meaningful in the context of the Mergers. DLJ
believed that an appropriate  use of a comparable  transaction analysis in  this
instance  would involve qualitative judgments concerning differences between the
characteristics of these  transactions and  the Mergers which  would affect  the
relative values of the merged companies and UCU and KCPL.
 
    PRO FORMA MERGER ANALYSIS.  DLJ analyzed the pro forma impact of the Mergers
on  the holders of shares of UCU Common  Stock, based on the Exchange Ratio. The
analysis was based on projections for UCU and KCPL prepared by their  respective
managements  for the years 1996, 1997, 1998, 1999 and 2000. The UCU projections,
provided by UCU management,  included a common  stock offering of  approximately
five  million shares expected to  be completed in 1996.  DLJ compared the EPS of
UCU Common Stock, on  a stand-alone basis, to  the EPS of Maxim  on a pro  forma
basis  (as adjusted for the Exchange Ratio). Based on such analysis and assuming
no synergies, the proposed transaction would  be dilutive to the holders of  UCU
Common  Stock on an EPS basis in the  years 1996, 1997, 1998, 1999 and 2000. The
proposed transaction would be accretive to  UCU stockholders on an EPS basis  in
the  years 1996, 1997, 1998, 1999 and 2000 assuming $25 million of annual pretax
retained  synergies  (amounts  DLJ  believed  to  be  achievable  based  on  its
discussions with UCU and KCPL).
 
    DLJ also analyzed the pro forma impact of the Mergers on the common dividend
per  share and dividend payout ratio (the "Payout Ratio") (defined as the common
dividend per share  divided by EPS)  to holders  of UCU Common  Stock. Based  on
Maxim's  announced common  dividend per  share of  $1.85 beginning  in 1998, DLJ
determined that Maxim's common  dividend per share would  be accretive to  UCU's
stand-alone  projected common dividend per share.  In addition, DLJ compared the
Payout Ratio of UCU Common Stock, on a stand-alone basis, to the Payout Ratio of
Maxim on a pro forma  basis. Based on such  analysis and assuming no  synergies,
the higher common dividend per share would increase the Payout Ratio for holders
of  UCU Common Stock in the years 1996,  1997, 1998, 1999 and 2000. As synergies
are realized and retained, the Payout Ratio will be reduced.
 
    In addition,  DLJ determined  the pro  forma impact  of the  Mergers on  the
end-of-year return on common equity ("ROE") (defined as the net income available
to the common equity divided by end-of-year common equity). DLJ compared the ROE
of UCU Common Stock, on a stand-alone basis, to the
 
                                       71
<PAGE>
ROE  of Maxim  on a  pro forma  basis. Based  on such  analysis and  assuming no
synergies, the proposed  transaction would increase  the ROE to  holders of  UCU
Common Stock in the years 1996, 1997, 1998, 1999 and 2000.
 
    RELATIVE  CONTRIBUTION ANALYSIS.  DLJ calculated the contribution of each of
UCU and  KCPL  to Maxim  with  respect to,  among  other things,  equity  market
capitalization,  enterprise  value  and  net  income  available  to  common. The
analysis indicated  that  UCU  would  contribute  44.5%  of  the  equity  market
capitalization,  52.5% of  the aggregate enterprise  value and 46.3%  of the net
income available to common of Maxim. The analysis indicated that UCU contributed
a higher percentage of  enterprise value than  equity market capitalization  and
net  income available to common  because of its higher  debt level. DLJ compared
UCU's relative contribution to 43.0%, its pro forma ownership of Maxim based  on
the Exchange Ratio.
 
    DISCOUNTED CASH FLOW ANALYSIS.  DLJ performed a DCF analysis of UCU and KCPL
using their respective management's projections.
 
    DLJ's  DCF  analysis  of  UCU  consisted of  a  segment  valuation  of UCU's
regulated  domestic  and  international   utility  businesses  (the   "Regulated
Businesses"),  Aquila,  UCU's  non-regulated gas  marketing,  transportation and
processing subsidiary, and UtilCo, UCU's non-regulated subsidiary with ownership
interests in independent power projects (collectively the "Segments"). For  each
of the Segments, DLJ calculated the present value of (i) the projected five-year
free  cash flow and (ii) the year 2000 value (the "Terminal Value") based upon a
range of multiples of  projected year 2000 EBIT.  The projections used in  DLJ's
DCF  analysis were provided to DLJ by UCU management. DLJ used multiples of EBIT
ranging from 9.0 to 11.0 for the  Regulated Businesses, 13.0 to 15.0 for  Aquila
and  10.0 to 12.0 for UtilCo. These  multiples were selected based on comparable
companies for  each  Segment's  business  and  based  on  DLJ's  experience  and
judgment. For the Regulated Businesses, DLJ reviewed the multiples of the Public
Comparables. For Aquila, DLJ reviewed the multiples for selected publicly-traded
companies   including  Tejas  Gas  Corp.,   Western  Gas  Resources,  Inc.,  NGC
Corporation and Mitchell Energy & Development Corp. For UtilCo, DLJ reviewed the
multiples for selected publicly-traded companies including AES Corp., California
Energy Co. Inc., Destec  Energy Inc., Sithe Energies  Inc., Trigen Energy  Corp.
and  Enron Global Power & Pipelines. DLJ  calculated the enterprise value of UCU
by taking the summation of the present  values calculated above for each of  the
Segments. In performing this analysis, DLJ used discount rates ranging from 7.0%
to  8.5%  for  each of  the  Segments.  These discount  rates  were  selected by
calculating the  weighted average  cost  of capital  for  each of  the  Segments
according  to the Capital Asset Pricing Model. The analysis indicated enterprise
values for UCU ranging from $3,208.5 million to $4,043.0 million.
 
    DLJ calculated the present value of free  cash flows for KCPL for the  years
1996 through 2000 using discount rates ranging from 7.5% to 9.5%. DLJ calculated
KCPL's  Terminal Value in the year 2000  based on multiples of EBIT ranging from
9.0 to 11.0 (which DLJ believed to  be appropriate based on KCPL's business  and
based  on DLJ's experience  and judgment) and discounted  this value by discount
rates ranging  from  7.5%  to  9.5%.  These  discount  rates  were  selected  by
calculating  the  weighted average  cost of  capital for  KCPL according  to the
Capital Asset Pricing Model. The  analysis indicated enterprise values for  KCPL
ranging from $2,295.3 million to $2,898.9 million. DLJ does not believe that the
exchange  ratios implied  by the DCF  of UCU and  KCPL should be  viewed as more
reliable than  any other  valuation  methodology DLJ  used  in arriving  at  its
opinion.
 
    DIVIDEND  DISCOUNT VALUATION  ANALYSIS.   DLJ performed  a dividend discount
valuation analysis for UCU and KCPL. DLJ calculated a range of equity values for
UCU Common Stock based upon  the sum of the present  value of (a) its  projected
dividends  for the years  1996 through 2000 and  (b) the year  2000 value of UCU
Common Stock assuming perpetual dividend growth rates ranging from 2.0% to 4.0%,
utilizing equity discount rates ranging from 10.0% to 11.5%. The equity discount
rates were  calculated  according  to  the Capital  Asset  Pricing  Model.  This
analysis was based upon projections and other information provided to DLJ by UCU
management.  DLJ  calculated a  range  of equity  values  for KCPL  Common Stock
utilizing the same perpetual  dividend growth rates  and based upon  projections
and  other  information provided  to DLJ  by  KCPL management,  utilizing equity
discount rates ranging
 
                                       72
<PAGE>
from 10.5% to 12.0%. This analysis  yielded exchange ratios ranging from  1.160x
to 1.180x. In arriving at the DLJ Opinion, DLJ considered, as one of the factors
in  its analysis, that the Exchange Ratio is outside the exchange ratios implied
by the dividend discount valuation of UCU and KCPL.
 
    DLJ has  indicated  to  UCU that  it  believes  that its  analyses  must  be
considered  as a whole and that selecting portions of the factors considered and
analyses performed, without considering all  factors and analyses, could  create
an  incomplete  view of  the  processes underlying  DLJ's  analyses and  the DLJ
Opinion. The preparation of a fairness opinion  is a complex process and is  not
necessarily  susceptible  to partial  analyses  or summary  description.  In its
analyses, DLJ did  not attribute any  particular weight to  any analysis  factor
considered  by it;  rather, DLJ  made its  determination as  to fairness  from a
financial point of view  based on qualitative judgments  as to the  significance
and  relevance of the  financial and comparative  analyses and factors described
above, taken as a whole. No company or transaction used in the above analyses as
a comparison  is identical  to  UCU or  KCPL  or the  contemplated  transaction.
Accordingly,  an analysis of  public comparables and  comparable transactions is
not  purely  quantitative;  rather,  it  involves  complex  considerations   and
judgments  concerning differences in financial  and operating characteristics of
the comparable companies and other factors that could affect the public  trading
value  of the comparable companies or company  to which they are being compared.
The analyses were prepared solely for the purpose of assisting DLJ in  providing
the  DLJ Opinion to the UCU  Board as to the fairness  from a financial point of
view of the Exchange Ratio to holders of UCU Common Stock and do not purport  to
be  appraisals and do not necessarily reflect  the prices at which companies may
actually be  sold. Analyses  based  upon forecasts  of  future results  are  not
necessarily indicative of actual future results, which may be significantly more
or  less  favorable  than  as  set  forth  herein.  Because  such  estimates are
inherently subject  to  uncertainty, DLJ  assumes  no responsibility  for  their
accuracy.  Although DLJ evaluated the fairness from a financial point of view of
the Exchange Ratio to holders of  UCU Common Stock, the specific Exchange  Ratio
was  determined by UCU and KCPL  through arm's-length negotiation. The foregoing
summary does not purport to be a complete description of the analysis  performed
by  DLJ and is  qualified by reference to  the DLJ Opinion set  forth in Annex C
hereto.
 
    DLJ is  an  internationally  recognized investment  banking  firm  which  is
continually  engaged  in the  valuation of  businesses  and their  securities in
connection with  transactions  and  acquisitions  and  other  purposes.  In  the
ordinary  course of  its business,  DLJ may actively  trade the  debt and equity
securities of UCU, KCPL and their subsidiaries  for its own account and for  the
accounts  of customers and,  accordingly, may, at  any time, hold  long or short
positions in such securities. DLJ has provided financial advisory and investment
banking services to UCU, KCPL and its affiliates in the past, for which services
it has received customary fees.
 
    For its services as financial advisor,  DLJ has received $2,000,000 in  fees
to  date and will receive an additional $5,000,000 advisory fee upon the closing
of the Mergers. UCU has also agreed to indemnify DLJ and certain related parties
against certain liabilities in connection with its engagement, including certain
liabilities under the federal securities laws.
 
CONFLICTS OF INTEREST
    In considering the recommendations of the KCPL Board and the UCU Board  with
respect  to the  Mergers, stockholders should  be aware that  certain members of
KCPL's and UCU's management  and Boards of Directors  have certain interests  in
the  Mergers that are in  addition to the interests  of stockholders of KCPL and
UCU generally. The Boards  of Directors of  each of KCPL and  UCU were aware  of
these  interests  and considered  them, among  other  matters, in  approving the
Merger Agreement, the Mergers and the transactions contemplated thereby.
 
    EMPLOYMENT AGREEMENTS.    The Employment  Agreements  with each  of  Messrs.
Jennings  and Green will become effective  upon the consummation of the Mergers.
The term of each Employment Agreement shall last until the fifth anniversary  of
the  Effective Time.  Pursuant to Mr.  Jennings' Employment  Agreement, from the
Effective Time until  the date of  the annual meeting  of shareholders of  Maxim
that  occurs  in  2002,  Mr.  Jennings will  serve  as  Chairman  of  Maxim, and
thereafter until the expiration of his  Employment Agreement will serve as  Vice
Chairman of Maxim. From the Effective
 
                                       73
<PAGE>
   
Time  until the  earlier of  the annual  meeting of  shareholders of  Maxim that
occurs in 2002 or the date Mr.  Jennings ceases to serve as Chairman, Mr.  Green
will serve as Vice Chairman and Chief Executive Officer of Maxim, and thereafter
until  the expiration  of his  Employment Agreement  will serve  as Chairman and
Chief  Executive  Officer.  See  "--  Employment  Agreements."  The   Employment
Agreements  with Messrs.  Jennings and Green  provide that each  will receive an
annual  base  salary,  short-term  and  long-term  incentive  compensation   and
supplemental retirement benefits no less than they received before the Effective
Time  and  no  less than  any  other  senior executive  officer  of  Maxim. Such
compensation continues to be set in the discretion of the KCPL Board and the UCU
Board, respectively. Based  upon current compensation  levels, Messrs.  Jennings
and  Green would each receive an annual  base salary of $630,000 and be eligible
for annual bonuses of  between $0 and  approximately $1,040,000, depending  upon
performance.  Under the  Employment Agreements, Mr.  Jennings and  Mr. Green may
become  entitled  to  certain  severance  benefits  upon  termination  of  their
employment  under specified circumstances. The amount  of such benefits is based
on, among other things, the remaining term of the Employment Agreement and their
compensation in effect at the time of such termination of employment. Based upon
the salary levels currently in effect, if the employment of Mr. Jennings or  Mr.
Green  is terminated immediately following the consummation of the Mergers under
circumstances entitling them to receive  severance benefits, they would each  be
entitled  to  a severance  payment ranging  from  approximately $1.9  million to
approximately $3.1 million, plus certain amounts in respect of bonuses and other
benefits. Because the maximum severance would be payable only if the  employment
of Mr. Jennings or Mr. Green is terminated immediately following consummation of
the  Mergers, and because the KCPL Board  and the UCU Board have determined that
it is in the best interest of Maxim to continue to employ both Mr. Jennings  and
Mr.  Green,  the Boards  believe that  it  is highly  unlikely that  the maximum
severence will actually become payable.
    
 
    EMPLOYEE  PLANS  AND  SEVERANCE  ARRANGEMENTS.    Under  certain   severance
arrangements  entered into by KCPL and  UCU, certain payments may become payable
in connection with the Mergers. In addition, stock options outstanding under the
UCU Plan and  the UCU 1986  Plan vested  upon execution of  the Original  Merger
Agreement.  Restricted stock outstanding under the  UCU 1986 Plan will vest upon
consummation of the Mergers. See "-- Employee Plans and Severance Arrangements."
 
    Each of KCPL's five most highly compensated executive officers have  entered
into  a KCPL  Severance Agreement.  Payments which  could be  made under certain
circumstances  to  such  individuals  in  the  event  of  their  termination  of
employment after the Mergers are as follows: Mr. A. Drue Jennings -- $2,275,384;
Mr.  Bernard  J. Beaudoin  -- $1,129,949;  Mr. Marcus  Jackson --  $861,161; Mr.
Ronald G. Wasson --  $1,045,065; Mr. J. Turner  White -- $780,736. In  addition,
each  of these  individuals, if  they receive  the severance  payments described
above, would also receive  the following amounts  in deferred compensation:  Mr.
Jennings  -- $282,196; Mr. Beaudoin -- $54,025; Mr. Jackson -- $0; Mr. Wasson --
$113,493; and Mr. White -- $0.
 
    Except for Mr. Charles  Dempster, each of the  five most highly  compensated
executive officers of UCU entered into a UCU Severance Agreement. Payments which
could  be made under certain circumstances  to such individuals upon termination
of their  employment after  the Mergers  are as  follows: Mr.  Richard Green  --
$1,890,000,  Mr. Robert  Green -- $1,440,000;  Mr. Burgess --  $722,304; and Mr.
Miller -- $841,548.
 
    Stock options vested for the five most highly compensated executive officers
of UCU are as follows: Mr. Richard Green -- 120,565 shares; Mr. Robert Green  --
74,194; Mr. Burgess -- 21,744; Mr. Dempster -- 41,582; and Mr. Miller -- 32,022.
Restricted  stock which will vest  for such officers is  as follows: Mr. Richard
Green -- 44,536 shares;  Mr. Robert Green  -- 19,601; Mr.  Burgess -- none;  Mr.
Dempster -- 4,132; and Mr. Miller -- 3,493.
 
    BOARD  OF DIRECTORS.  As provided in  the Merger Agreement, at the Effective
Time, the Maxim Board  will consist of  18 directors, nine of  whom will be  the
then  existing  directors  of  KCPL immediately  prior  to  the  Effective Time,
including Mr. Jennings, and nine of whom will be designated by UCU. To date, UCU
has not determined which individuals, in addition to Richard C. Green, Jr., will
be its  designees to  serve as  directors of  Maxim as  of the  Effective  Time.
However, it is currently
 
                                       74
<PAGE>
anticipated  that the directors  of UCU immediately prior  to the Effective Time
will serve  as UCU's  designees to  the Maxim  Board. See  "MAXIM FOLLOWING  THE
MERGERS -- Maxim Board of Directors."
 
    INDEMNIFICATION.  The parties have agreed in the Merger Agreement that Maxim
will  indemnify, to the fullest extent  permitted by applicable law, the present
and former  officers, directors  and employees  of each  of the  parties to  the
Merger  Agreement or any  of their Subsidiaries  against certain liabilities (i)
arising out of actions or omissions occurring at or prior to the Effective  Time
that arise from or are based on such service as an officer, director or employee
or  (ii)  that are  based on  or arise  out  of or  pertain to  the transactions
contemplated by the Merger Agreement, and to maintain policies of directors' and
officers' liability insurance for a period of not less than six years after  the
Effective  Time, provided that Maxim shall not be required to expend in any year
an amount in excess of  200% of the annual  aggregate premium currently paid  by
KCPL  and UCU for such  insurance. To the fullest  extent permitted by law, from
and after the Effective Time, all rights to indemnification existing in favor of
the employees, agents, directors or officers  of KCPL, UCU and their  respective
Subsidiaries  with respect  to their activities  as such prior  to the Effective
Time, as provided in  their respective articles of  incorporation and bylaws  in
effect  on January 19, 1996,  or otherwise in effect  on January 19, 1996, shall
survive the Mergers and shall continue in full force and effect for a period  of
not  less than six years  from the Effective Time.  See "THE MERGER AGREEMENT --
Directors' and Officers' Indemnification."
 
CERTAIN ARRANGEMENTS REGARDING THE DIRECTORS AND MANAGEMENT OF MAXIM
 
    In connection with the Mergers, the Maxim Board, at the Effective Time, will
consist of 18 persons, nine of whom will be the then existing directors of  KCPL
immediately  prior to the Effective Time, and nine of whom will be designated by
UCU. To date, UCU has not  determined which individuals, in addition to  Richard
C.  Green, Jr., will be its  designees to serve as directors  of Maxim as of the
Effective Time. However, it is currently  anticipated that the directors of  UCU
immediately  prior to the Effective Time will  serve as the initial directors of
Maxim. Robert K. Green, brother of Richard C. Green, Jr., will be the  president
of  Maxim and Marcus Jackson will serve  as Maxim's executive vice president and
chief operating  officer. Robert  K. Green  is currently  president of  UCU  and
Marcus Jackson is senior vice president and chief operating officer of KCPL. See
"MAXIM  FOLLOWING THE MERGERS -- Maxim Board of Directors" and "-- Management of
Maxim."
 
    The Merger Agreement provides that  during the three-year period  commencing
at the Effective Time, certain provisions thereof (including provisions relating
to  existing employee agreements, workforce matters, benefit plans, stock option
and other  plans and  certain officer  positions of  Maxim) may  be enforced  on
behalf of the officers, directors and employees of KCPL and UCU, as the case may
be, by the directors of Maxim designated by KCPL and UCU, respectively (or their
successors).
 
EMPLOYMENT AGREEMENTS
 
    Forms  of  the  Employment  Agreements of  Messrs.  Jennings  and  Green are
attached hereto as Annexes F and G, respectively. Messrs. Jennings and Green are
sometimes  hereinafter  individually  referred   to  as  the  "Executive."   The
Employment  Agreements will  become effective  only at  the Effective  Time. The
provisions of the Employment Agreements which relate to the Executive serving as
a director on the Maxim Board assume that the Executive is elected to the  Maxim
Board by Maxim shareholders.
 
    The term of each Employment Agreement shall last until the fifth anniversary
of  the Effective Time. Pursuant to Mr. Jennings' Employment Agreement, from the
Effective Time until  the date of  the annual meeting  of shareholders of  Maxim
that  occurs  in  2002,  Mr.  Jennings will  serve  as  Chairman  of  Maxim, and
thereafter until the expiration of his  Employment Agreement will serve as  Vice
Chairman  of Maxim.  From the  Effective Time  until the  earlier of  the annual
meeting of shareholders of Maxim  that occurs in 2002  or the date Mr.  Jennings
ceases  to serve as  Chairman, Mr. Green  will serve as  Vice Chairman and Chief
Executive  Officer  of  Maxim,  and  thereafter  until  the  expiration  of  his
Employment Agreement will serve as Chairman and Chief Executive Officer.
 
                                       75
<PAGE>
    Each Employment Agreement provides that the Executive will receive an annual
base  salary, short-term  and long-term incentive  compensation (including stock
options and restricted stock) and supplemental retirement benefits no less  than
they  received before the Effective Time, as  well as life insurance providing a
death benefit of three times their  annual base salaries. The Executive is  also
entitled  to  retirement  and  welfare  benefits  on  the  same  basis  as other
executives, and certain  fringe benefits  and to an  unreduced early  retirement
benefit under certain circumstances.
 
    CERTAIN  OBLIGATIONS OF MAXIM UPON TERMINATION  OF EMPLOYMENT AGREEMENT.  If
Maxim terminates the employment of the Executive without "cause" (as defined  in
the  Employment Agreements) or the Executive terminates his employment for "good
reason" (as defined  in the  Employment Agreements,  and which  term includes  a
termination  by the Executive for any reason during the 30-day period commencing
on the third anniversary of the UCU Effective Time), (i) Maxim shall pay to  the
Executive  in a lump  sum, a cash amount  equal to (a) the  present value of the
Executive's annual base salary and incentive compensation (assuming targets have
been met) payable through the end of the term of the Employment Agreement or, if
longer, for a  period of three  years (the "Continuation  Period"), each at  the
rate  in effect at  the time of  termination of the  Executive's employment, (b)
except with respect to benefits described in clause (ii) below, the value of all
insurance, expenses and  fringe benefits to  which he would  have been  entitled
through  the Continuation Period and (c)  the value of all deferred compensation
amounts (together with accrued interest or earnings thereon), and all  executive
life  insurance benefits whether or  not then vested or  payable, and (ii) Maxim
shall continue medical and welfare benefits  to the Executive and/or his  family
at  least equal to those which would have been provided had he remained employed
by Maxim  through the  end of  the Continuation  Period. If  the Executive  dies
during  the term of the Employment Agreement, Maxim will pay to the Executive or
his beneficiaries or estate  all compensation earned through  the date of  death
(including  previously deferred compensation and pro rata incentive compensation
based upon the  maximum potential  awards). If  the Executive  is terminated  by
Maxim  for  cause or  if the  Executive terminates  his employment  without good
reason, Maxim will pay his base salary through the date of termination plus  any
previously  deferred compensation. Any amounts paid to the Executive pursuant to
his severance agreement will be netted against amounts due under his  Employment
Agreement. See "-- Employee Plans and Severance Arrangements."
 
EMPLOYEE PLANS AND SEVERANCE ARRANGEMENTS
 
    UCU  has  entered  into Severance  Compensation  Agreements with  36  of its
officers (each, a "UCU Severance  Agreement"). The UCU Severance Agreements  are
intended  to provide for continuity  of management in the  event of a "change of
control" of  UCU  or a  "spin-off  "  of a  business  unit of  UCU.  Under  such
agreements,  executives are entitled to certain severance benefits if, following
a (a) "change  of control," the  executive's employment with  UCU is  terminated
within  the three-year period following the "change of control," (b) "spin-off "
affecting the  executive,  the  executive  is terminated  and  does  not  become
employed by the "spin-off purchaser" or (c) "spin-off " affecting the executive,
the  executive's employment with  the "spin-off purchaser"  is terminated within
the one-year  period following  the  "spin-off," unless  such termination  is  a
result of the executive's (i) "disability," (ii) "retirement," (iii) termination
for  "cause,"  or (iv)  decision to  terminate employment  other than  for "good
reason" (each as defined  in the UCU  Severance Agreements). Severance  benefits
include  (A) a lump-sum cash amount equal to 2.99 times the executive's "average
annual compensation" in the event of a "change in control," or (B) 1.0 times the
executive's "average  annual compensation"  in  the event  of a  "spin-off."  In
addition,  each UCU Severance  Agreement provides for  (1) acceleration of stock
options granted to  the executive pursuant  to UCC's stock  incentive plan,  (2)
lapsing  of any  restrictions relating  to stock awards  under such  plan, (3) a
lump-sum cash payment of any deferred compensation, (4) immediate vesting in any
long-term incentive  compensation  under  UCU's long-term  incentive  plan,  (5)
payment of a percentage of the cost of insurance continuation benefits on behalf
of  the executive pursuant to the Consolidated Omnibus Budget Reconciliation Act
of 1986 and  any other  benefits relating  to health  or medical  care that  are
available under UCU policy to the executive following termination of employment,
and (6) a lump-sum cash amount equal to the
 
                                       76
<PAGE>
annual  incentive paid to the executive in each of the immediately preceding two
calendar years, in the event of a  "change in control," other than a  "spinoff,"
or  in the  immediately preceding  calendar year in  the event  of a "spin-off."
Severance benefits to executives are effectively limited by Section 280G of  the
Code, and are therefore subject to adjustment in the event it is determined that
such  benefits exceed or fall below the maximum amount permitted under the Code.
The Mergers will, at  the Effective Time, constitute  a "change in control."  If
benefits become payable under all of the UCU Severance Agreements, the aggregate
amount  that Maxim  would be required  to pay thereunder  would be approximately
$20.5 million.
 
    KCPL has entered into severance agreements with a number of its  executives,
including  its seven  most senior  executives (each  agreement with  such senior
executives, a "KCPL Severance Agreement"). Each of the KCPL Severance Agreements
provides for the payment  of severance benefits  upon termination of  employment
with  KCPL (a) during the three-year period beginning with a "change in control"
of KCPL (or, if  later, beginning with the  consummation of the transaction  the
approval  of  which by  KCPL's shareholders  constitutes  a change  in control),
unless such termination of employment  is (i) by KCPL  for "cause," (ii) by  the
senior executive for any reason other than "good reason" (each as defined in the
KCPL  Severance Agreements) or (iii) as a result of the senior executive's death
or disability or (b) during the  30-day period commencing one year after  change
in control (or, if later, beginning with the consummation of the transaction the
approval of which by KCPL's shareholders constitutes a change in control).
 
    If  a senior  executive's employment  is terminated  under the circumstances
described in the immediately  preceding paragraph, KCPL is  obligated to pay  or
provide  to such executive the following benefits: (A) a lump-sum cash amount in
an amount equal to  (i) three times the  senior executive's highest annual  base
salary  as in effect during the 12-month period immediately prior to the date of
termination, plus (ii)  three times  the senior  executive's average  annualized
incentive  compensation awards  paid or payable  pursuant to  the KCPL Incentive
Compensation Plan during the five fiscal years immediately preceding the  fiscal
year  in which the Mergers occur; (B) a  lump-sum cash amount equal to the value
of three additional years  of credit service under  the KCPL Management  Pension
Plan  and any  related agreement, and  (C) a  lump-sum cash amount  equal to the
value of  the unvested  portion (if  any) of  such senior  executive's  employer
matching contributions under the KCPL Cash or Deferred Arrangement. In addition,
each  KCPL Severance  Agreement provides  for three  years' continuation  of all
medical, accident,  disability and  life  insurance plans  with respect  to  the
senior  executive.  The  KCPL  Severance Agreements  provide  for  an additional
payment to be  made to the  senior executive  in order to  indemnify the  senior
executive  for any excise tax imposed by Section 4999 of the Code on any payment
or distribution by KCPL or its affiliated companies to or for the benefit of the
senior  executive.  If  benefits  become   payable  under  the  KCPL   Severance
Agreements,  the aggregate amount that Maxim would be required to pay thereunder
to the five most highly compensated officers of KCPL would be approximately $6.1
million.
 
MAXIM PLANS
 
    Pursuant to the  terms of  the Merger  Agreement, Maxim  will implement  the
Maxim Plans described below, subject to shareholder approval thereof at the KCPL
Meeting. Each of the Maxim Plans will become effective as of the Effective Time.
 
    MAXIM STOCK INCENTIVE PLAN.  This plan is a comprehensive stock compensation
plan  designed to provide Maxim with the ability to provide incentives linked to
the profitability  of its  businesses and  increases in  stockholder value.  The
Maxim  Stock Incentive Plan  provides for the grant  of stock options, including
incentive stock options ("ISOs"), stock appreciation rights ("SARs"), restricted
stock and performance units. The maximum number of shares of Maxim Common  Stock
available  for issuance under  the plan is  9,000,000 shares, but  not more than
3,000,000 shares  may be  issued  as restricted  stock,  no participant  may  be
granted awards covering in excess of 600,000 shares of Maxim Common Stock in any
one year and no participant may be granted performance units in any one calendar
year  payable in cash in an amount  that would exceed $2,000,000. The Nominating
and
 
                                       77
<PAGE>
Compensation Committee of the Maxim  Board (the "Maxim Compensation  Committee")
will  administer  the  plan and  make  awards  thereunder, and  will  have broad
authority to  fix  the  terms  and  conditions  of  individual  agreements  with
participants. This plan is being submitted to shareholders of KCPL for approval,
and is described in greater detail under "APPROVAL OF MAXIM PLANS -- Maxim Stock
Incentive  Plan" elsewhere in  this Joint Proxy  Statement/Prospectus; a copy of
the plan is  attached as Annex  D. Following implementation  of the Maxim  Stock
Incentive Plan, no further obligations will be incurred under the existing stock
incentive plans of KCPL and UCU.
 
    MAXIM  MIC  PLAN.   This plan  is a  short-term incentive  compensation plan
designed to benefit eligible employees of Maxim and its subsidiaries. The  Maxim
MIC  Plan rewards key  management personnel for  meeting established individual,
group and  corporate goals.  Employees  who participate  in  this plan  will  be
granted  awards payable in cash, shares of Maxim Common Stock or such other form
as may  be  determined  by  the  Maxim  Compensation  Committee  to  the  extent
predetermined goals are attained within the performance period. Awards are based
on  a  percentage of  a participant's  annual  base salary.  This plan  is being
submitted to shareholders  of KCPL  for approval,  and is  described in  greater
detail under "APPROVAL OF MAXIM PLANS -- Maxim MIC Plan" elsewhere in this Joint
Proxy Statement/Prospectus; a copy of the plan is attached as Annex E. Following
implementation  of the Maxim  MIC Plan, no further  obligations will be incurred
under the existing short-term incentive plans of KCPL and UCU.
 
    ACTIONS WITH RESPECT TO  EXISTING STOCK OPTIONS  AND CERTAIN OTHER  EXISTING
ARRANGEMENTS.   All  stock options  to acquire  UCU Common  Stock under  the UCU
Employee  Stock  Option  Plan  and  UCU  1986  Stock  Incentive  Plan  that  are
outstanding  at the Effective Time  will be converted into  options to buy Maxim
Common Stock, and  the number of  shares and exercise  price under such  options
will  be  adjusted  so as  to  preserve both  the  same aggregate  gain  or loss
immediately after the Effective Time as existed immediately before the Effective
Time and the ratio of the exercise price per share subject to such stock  option
to  the fair market value  per underlying share, provided,  however, that in the
case of any stock option which is intended to be an ISO, the conversion shall be
adjusted, if necessary, to  comply with Section 424(a)  of the Code. Maxim  will
assume  the obligation  to honor such  options and any  other outstanding awards
under the existing stock incentive plans of UCU, and the terms and conditions of
such options and awards will otherwise  remain the same as before the  Effective
Time  after giving effect to  the conversion ratio of  the UCU Common Stock. See
"THE MERGER AGREEMENT -- Benefit Plans."
 
DIVIDEND REINVESTMENT PLAN
 
    It is anticipated that, after the Effective Time, Maxim will have a dividend
reinvestment  and  stock  purchase  plan.  Participants  in  the  KCPL  Dividend
Reinvestment  Plan  immediately prior  to the  Effective  Time will  continue to
participate in the Maxim dividend reinvestment and stock purchase plan after the
Effective Time. Following the Effective Time, former common stockholders of  UCU
will  be  able  to participate  in  the  Maxim dividend  reinvestment  and stock
purchase plan with respect to the shares of Maxim Common Stock that they receive
in  the  UCU  Merger,  and  to  have  their  accounts  under  the  UCU  Dividend
Reinvestment  and Common Stock  Purchase Plan transferred  to the Maxim dividend
reinvestment and  stock purchase  plan. Stockholders  of KCPL  and UCU  will  be
notified  as to the terms of the  Maxim dividend reinvestment and stock purchase
plan as soon as practicable after such terms have been finalized.
 
CERTAIN FEDERAL INCOME TAX CONSEQUENCES
 
    CONSEQUENCES TO EXCHANGING STOCKHOLDERS.  The consummation of the Mergers is
conditioned upon the receipt  by KCPL of  an opinion from  Skadden Arps and  the
receipt  by  UCU of  an opinion  from Blackwell  Sanders, each  dated as  of the
Effective Time,  substantially  to the  effect  that,  on the  basis  of  facts,
representations  and assumptions set forth therein: (i)  no gain or loss will be
recognized by KCPL, UCU or Maxim pursuant  to the Mergers; (ii) with respect  to
the  opinion  of  Blackwell Sanders,  no  gain  or loss  will  be  recognized by
stockholders   of   UCU    who   exchange   their    shares   of   UCU    Common
 
                                       78
<PAGE>
Stock  for shares of  Maxim Common Stock as  a result of  the Mergers; and (iii)
with respect to the opinion of Skadden Arps, no gain or loss will be  recognized
by shareholders of KCPL as a result of the Mergers.
 
    The aggregate tax basis of the Maxim Common Stock received in the UCU Merger
will  be  the same  as the  tax basis  in  the UCU  Common Stock  surrendered in
exchange therefor. The holding period of the Maxim Common Stock received in  the
UCU Merger will include the period during which the UCU Common Stock surrendered
in  exchange therefor  was held (provided  such UCU  Common Stock was  held as a
capital asset at the UCU Effective Time).
 
    THE DISCUSSION SET FORTH ABOVE IS INCLUDED FOR GENERAL INFORMATION ONLY  AND
DOES  NOT ADDRESS THE STATE, LOCAL, FOREIGN INCOME AND OTHER TAX CONSEQUENCES OF
THE MERGERS. FURTHER, THE DISCUSSION MAY  NOT APPLY TO PARTICULAR CATEGORIES  OF
STOCKHOLDERS  OF  UCU, INCLUDING  (I) STOCKHOLDERS  WHO  ACQUIRED SHARES  OF UCU
COMMON STOCK PURSUANT TO THE EXERCISE OF EMPLOYEE STOCK OPTIONS OR OTHERWISE  AS
COMPENSATION,  (II) INDIVIDUALS WHO ARE NOT  CITIZENS OR RESIDENTS OF THE UNITED
STATES, (III) FOREIGN CORPORATIONS AND (IV) ENTITIES THAT ARE OTHERWISE  SUBJECT
TO SPECIAL TAX TREATMENT UNDER THE CODE (SUCH AS INSURANCE COMPANIES, TAX-EXEMPT
ENTITIES  AND REGULATED  INVESTMENT COMPANIES). THE  DISCUSSION IS  BASED ON THE
CODE AS IN EFFECT  ON THE DATE OF  THIS JOINT PROXY STATEMENT/PROSPECTUS,  WHICH
MAY DIFFER AT THE EFFECTIVE TIME. STOCKHOLDERS OF UCU ARE URGED TO CONSULT THEIR
TAX  ADVISORS  WITH RESPECT  TO THE  SPECIFIC  TAX CONSEQUENCES  TO THEM  OF THE
MERGERS, INCLUDING THE APPLICATION TO THEM AND POSSIBLE EFFECT UPON THEM OF  ANY
PENDING  LEGISLATION, THE ALTERNATIVE MINIMUM TAX,  AND STATE, LOCAL AND FOREIGN
INCOME AND OTHER TAX LAWS.
 
ACCOUNTING TREATMENT
 
    It is intended that the Mergers will  qualify as a pooling of interests  for
accounting  and financial reporting  purposes. Under this  method of accounting,
the recorded assets and liabilities of KCPL  and UCU will be carried forward  to
the consolidated financial statements of Maxim at their recorded amounts; income
of Maxim will include income of KCPL and UCU for the entire fiscal year in which
the  Mergers occur;  and the  reported income  of the  separate corporations for
prior periods will be combined and restated  as income of Maxim. The receipt  by
each  of KCPL and UCU of a letter from their respective independent accountants,
stating that the Mergers will qualify as a pooling of interests, is a  condition
precedent to consummation of the Mergers. This condition may be waived, but KCPL
and  UCU presently  have no  intention to  do so.  Representatives of  Coopers &
Lybrand L.L.P. and Arthur Andersen  LLP are expected to  be present at the  KCPL
Meeting  and  the  UCU  Meeting,  respectively.  See  "THE  MERGER  AGREEMENT --
Conditions to Each Party's Obligation to Effect the Mergers" and "UNAUDITED  PRO
FORMA COMBINED FINANCIAL INFORMATION."
 
STOCK EXCHANGE LISTING OF THE MAXIM COMMON STOCK
 
    KCPL  will apply for the listing on the NYSE of the Maxim Common Stock to be
issued in the UCU Merger. It is  a condition to the consummation of the  Mergers
that  the Maxim  Common Stock  to be issued  in the  UCU Merger  be approved for
listing on the  NYSE, subject to  official notice  of issuance. So  long as  UCU
continues to meet applicable requirements, the UCU Common Stock will continue to
be  listed on the NYSE and each of the other securities exchanges on which it is
listed until the UCU Effective Time.  In addition, until called for  redemption,
all  classes and series of preferred stock of KCPL and of UCU will remain listed
on any securities exchange on which such preferred stock is presently listed.
 
FEDERAL SECURITIES LAW CONSEQUENCES
 
    All shares of  Maxim Common Stock  received by holders  of UCU Common  Stock
will  be freely transferable, except that  shares of Maxim Common Stock received
by persons who are deemed to be "affiliates" (as such term is defined under  the
Securities Act) of UCU prior to the Mergers may be
 
                                       79
<PAGE>
resold  by them only in transactions permitted  by the resale provisions of Rule
145 promulgated under  the Securities  Act (or  Rule 144,  in the  case of  such
persons  who become  affiliates of  Maxim) or  as otherwise  permitted under the
Securities  Act.  Persons  who  may  be  deemed  to  be  affiliates  of  UCU  or
Maxim generally include individuals or entities that control, are controlled by,
or  are under common control  with, such party and  may include certain officers
and directors of such party as well as principal stockholders of such party. The
Merger Agreement requires UCU to use all reasonable efforts to cause each of its
affiliates to execute a written agreement to the effect that such affiliate will
not offer or sell or otherwise dispose  of (i) any shares of Maxim Common  Stock
during  the period beginning 30 days prior  to the Effective Time and continuing
until such time  as results  covering at least  30 days  of post-Effective  Time
operations  of Maxim have been published or (ii) any of the shares of UCU Common
Stock or  any shares  of  Maxim Common  Stock issued  to  such affiliate  in  or
pursuant  to the  Mergers in violation  of the  Securities Act or  the rules and
regulations promulgated by the SEC thereunder.
 
    This Joint Proxy Statement/Prospectus does not cover resales of Maxim Common
Stock received in the Mergers by any person who may be deemed to be an affiliate
of UCU or Maxim.
 
DISSENTERS' RIGHTS
 
    KCPL.  Holders  of KCPL  Common Stock will  not have  dissenters' rights  of
appraisal under the MGBCL with respect to the Consolidating Merger or any of the
other transactions contemplated by the Merger Agreement.
 
    UCU.    Holders of  UCU Common  Stock  will not  have dissenters'  rights of
appraisal under the  DGCL with respect  to the UCU  Merger or any  of the  other
transactions contemplated by the Merger Agreement.
 
REGULATORY MATTERS
 
    As  indicated  below, consummation  of the  Mergers  is subject  to numerous
regulatory approvals,  which are  presently anticipated  to be  received by  the
second  quarter of 1997. KCPL and UCU do not expect that obtaining such required
regulatory approvals will be delayed by  reason of amending the Original  Merger
Agreement.  Set forth below is a summary of the material regulatory requirements
affecting the Mergers.
 
    STATE APPROVALS  AND RELATED  MATTERS.   KCPL currently  is subject  to  the
jurisdiction  of the Missouri Commission and  the Kansas Commission with respect
to its utility operations in those states.
 
    UCU currently is subject  to the jurisdiction of  the Kansas Commission,  as
well  as the Colorado  Public Utilities Commission  (the "Colorado Commission"),
the Iowa State Utilities Board (the  "Iowa Board"), the Michigan Public  Service
Commission   (the  "Michigan   Commission"),  the   Minnesota  Public  Utilities
Commission (the "Minnesota Commission"), the Missouri Public Service  Commission
(the "Missouri Commission") and the West Virginia Public Service Commission (the
"West  Virginia Commission")  with respect  to its  utility operations  in those
states. In  addition, certain  utility  activities of  UCU  and certain  of  its
Subsidiaries  are subject to the jurisdiction  of the British Columbia Utilities
Commission (the  "British  Columbia  Commission"). The  Treasurer  of  Australia
(Foreign  Investment Review  Board) (the "Treasurer  of Australia")  and the New
Zealand Overseas  Investment  Commission  (the "New  Zealand  Commission")  also
regulate the investment activities of UCU in Australia and New Zealand.
 
    Applications for approval, or waiver of approval, of the Mergers and related
transactions,  including, in  the case of  certain commissions,  the issuance of
securities  in  connection  therewith,  are   being  filed  with  the   Missouri
Commission,  the Kansas Commission, the Colorado Commission, the Iowa Board, the
Michigan Commission, the Minnesota Commission, the West Virginia Commission, the
British Columbia  Commission, the  Treasurer of  Australia and  the New  Zealand
Commission.
 
                                       80
<PAGE>
    Assuming  the requisite  regulatory approvals are  obtained, Maxim's utility
operations will be subject to regulation by the Missouri Commission, the  Kansas
Commission,  the Colorado Commission,  the Iowa Board,  the Michigan Commission,
the Minnesota Commission, the West Virginia Commission and the British  Columbia
Commission,  and certain non-utility operations will be subject to regulation in
Oklahoma, South Dakota and Texas. In addition, certain investment activities  of
Maxim  in Australia and New  Zealand will be subject  to the jurisdiction of the
Treasurer of Australia and the New Zealand Commission, respectively.
 
    PUBLIC UTILITY HOLDING  COMPANY ACT OF  1935.  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). UCU  is a gas and electric utility  company
and  a holding company that is exempt pursuant to Rule 10 from all provisions of
the 1935 Act except Section 9(a)(2), which generally requires SEC approval prior
to the direct or indirect acquisition of 5% or more of the voting securities  of
more than one electric or gas utility company.
 
    KCPL  and UCU intend to  request a "no-action" letter  from the staff of the
SEC, confirming  their view  that (i)  the Mergers  will not  require the  prior
approval  of  the SEC  pursuant  to Section  9(a)(2) of  the  1935 Act  and (ii)
following consummation of the Mergers, Maxim will be a holding company  entitled
to  claim exemption pursuant to  Rule 10 from all provisions  of the Act. In the
event that the staff  of the SEC does  not concur with this  view, KCPL and  UCU
will file an application with the SEC for the necessary approvals and exemptions
in connection with the Mergers.
 
    FEDERAL  POWER ACT.  Section  203 of the Federal  Power Act 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.  The approval of the FERC is
required in order to  consummate the Mergers. Under  Section 203 of the  Federal
Power  Act, the FERC will  approve a merger if  it finds such merger "consistent
with the public interest." In reviewing a merger, the FERC generally  evaluates:
(i)  whether  the merger  will adversely  affect  competition, (ii)  whether the
merger will adversely affect operating costs and rates, (iii) whether the merger
will impair the effectiveness of regulation, (iv) whether the purchase price  is
reasonable,  (v) whether the merger is the  result of coercion, and (vi) whether
the accounting treatment is reasonable. On March 29, 1996, KCPL and UCU filed  a
combined  application with the FERC requesting that the FERC approve the Mergers
under Section 203 of the Federal Power Act (the "Application"). The  Application
will  be amended to reflect the terms of the Merger Agreement as compared to the
Original Merger Agreement. In connection with the Application, KCPL and UCU also
filed a comparable transmission service tariff under Section 205 of the  Federal
Power Act, to become effective upon consummation of the Mergers.
 
    ANTITRUST  CONSIDERATIONS.    The  HSR Act  and  the  rules  and regulations
promulgated thereunder provide that certain transactions (including the Mergers)
may not  be consummated  until certain  information has  been submitted  to  the
Antitrust  Division of the Department of  Justice (the "Antitrust Division") and
the Federal Trade Commission  (the "FTC") and specified  HSR Act waiting  period
requirements  have been satisfied. The expiration  or earlier termination of the
HSR Act waiting period would not preclude the Antitrust Division or the FTC from
challenging the Mergers on antitrust grounds. Neither KCPL nor UCU believes that
the Mergers  will  violate  federal  antitrust laws.  If  the  Mergers  are  not
consummated  within 12 months after the expiration or earlier termination of the
initial HSR Act waiting  period, KCPL and  UCU would be  required to submit  new
information  to the Antitrust  Division and the  FTC, and a  new HSR Act waiting
period would have to expire or be earlier terminated before the Mergers could be
consummated. KCPL and UCU intend to file their premerger notifications  pursuant
to  the HSR Act  at such time as  they believe will result  in the expiration or
termination of  the  waiting  period  thereunder within  12  months  before  the
anticipated consummation of the Mergers.
 
    ATOMIC  ENERGY ACT OF  1954, AS AMENDED.   KCPL holds an  interest in an NRC
license in connection  with its  ownership interest  in the  Wolf Creek  nuclear
generating facility and its operator, the Wolf
 
                                       81
<PAGE>
Creek  Nuclear  Operating  Corporation ("WCNOC").  The  WCNOC  operating license
authorizes KCPL to own 47% of the  facility and 47% of WCNOC. The Atomic  Energy
Act  provides that such licenses or any  rights thereunder may not be amended or
transferred or in any manner disposed of, directly or indirectly, to any  person
through  transfer  of control  unless the  NRC  finds that  such transfer  is in
accordance with the Atomic Energy Act and consents to the transfer. Pursuant  to
the  Atomic Energy Act, KCPL and UCU will  seek approval from the NRC to reflect
the fact that  after the Mergers,  WCNOC and the  Wolf Creek nuclear  generating
facility will be owned 47% by Maxim.
 
    OTHER.   KCPL and UCU possess municipal franchises and environmental permits
and licenses that require the consent of the licensor to the Mergers or may need
to be renewed, replaced or transferred as a result of the Mergers. Neither  KCPL
nor  UCU  anticipate any  difficulties  at the  present  time in  obtaining such
consents, renewals, replacements or transfers.
 
    GENERAL.  Under the Merger  Agreement, KCPL and UCU  have agreed to use  all
commercially  reasonable  efforts  to obtain  all  necessary  permits, consents,
approvals and  authorizations  of  all  governmental  authorities  necessary  or
advisable  to consummate or  effect the transactions  contemplated by the Merger
Agreement. Various parties may seek intervention in these proceedings to  oppose
the  Mergers  or  to  have  conditions imposed  upon  the  receipt  of necessary
approvals. While  KCPL and  UCU believe  that they  will receive  the  requisite
regulatory approvals for the Mergers, there can be no assurance as to the timing
of  such approvals or  the ability of  such parties to  obtain such approvals on
satisfactory terms or otherwise.  It is a condition  to the consummation of  the
Mergers  that final  orders approving the  Mergers be obtained  from the various
federal and  state commissions  described above  on terms  and conditions  which
would  not have, or foreseeably could not have, a material adverse effect on the
business, assets, financial condition or results of operations of Maxim and  its
prospective  subsidiaries  taken  as  a  whole,  or  which  would  be materially
inconsistent with  the  agreements  of  the  parties  contained  in  the  Merger
Agreement.  There can be no  assurance that any such  approvals will not contain
terms or conditions that cause such approvals to fail to satisfy such  condition
to the consummation of the Mergers.
 
CERTAIN LITIGATION
 
    On  May 20,  1996, KCPL commenced  litigation captioned KANSAS  CITY POWER &
LIGHT CO. v.  WESTERN RESOURCES, INC.,  ET AL., C.A.  No. 96-0552-CV-W-5 in  the
United  States  District Court  for the  Western  District of  Missouri, Western
Division, against Western  Resources and  Robert L. Rives.  In this  litigation,
KCPL  is  seeking  a declaratory  judgment  that  the Merger  Agreement  and the
transaction contemplated thereby were adopted and may be completed in accordance
with Missouri  law  and  are  not  void,  voidable,  subject  to  injunction  or
rescission  based upon any claim that KCPL's directors, officers or agents acted
illegally or inequitably  in adopting the  Merger Agreement. KCPL  also seeks  a
declaratory  judgment  that Western  Resources lacks  standing to  challenge the
Merger Agreement, the transaction contemplated  thereby, or the acts leading  to
its adoption.
 
    On  May 24, 1996, Jack R. Manson  ("Manson"), a shareholder of KCPL, filed a
motion to  intervene  in  the  above  action as  a  representative  of  a  class
consisting  of similarly situated KCPL shareholders. Manson also requested leave
to file  an answer  to the  complaint, in  which he  would assert  counterclaims
against  KCPL and  each of  its directors, who  would be  joined as counterclaim
defendants. The proposed counterclaims would allege that KCPL and its  directors
breached  fiduciary  duties of  care, loyalty  and  disclosure in  responding to
Western Resources' acquisition overtures, including their adoption of the Merger
Agreement; that their actions in adopting the Merger Agreement were illegal  and
ULTRA  VIRES; that the adoption of  the Merger Agreement illegally deprived KCPL
shareholders of voting  and appraisal rights  under Missouri law;  and that  the
adoption  of the  Merger Agreement  was a  disproportionate response  to Western
Resources' acquisition offer.  On June  7, 1996,  this motion  to intervene  was
granted.  KCPL believes  that the proposed  counterclaims are  without merit and
will vigorously defend.
 
    On June 7, 1996, Western Resources  and Rives answered the complaint in  the
above  action and made two counterclaims  against KCPL, alleging that the Merger
Agreement is illegal under Missouri
 
                                       82
<PAGE>
law because it does not require  approval of two-thirds of all outstanding  KCPL
shares  and does not  provide dissenters' rights to  KCPL shareholders, and that
the directors of  KCPL breached their  fiduciary duties by  adopting the  Merger
Agreement.  KCPL believes  that these counterclaims  are without  merit and will
vigorously defend.
 
    During a  June  13,  1996 telephone  conference  concerning  scheduling  the
proceedings  in the above litigation, the court indicated that the issues of the
legality of the Merger Agreement and its adoption would be heard by the court on
July 25, 1996.
 
                              THE MERGER AGREEMENT
 
    The following is a  summary of certain provisions  of the Merger  Agreement,
which  is attached as  Annex A hereto  and is incorporated  herein by reference.
Such summary is qualified in its entirety by reference to the Merger Agreement.
 
THE MERGERS
 
    IN GENERAL.  The Merger Agreement  provides that, following the approval  of
the  Share  Issuance  by  the  shareholders  of  KCPL  (the  "KCPL Shareholders'
Approval"), and  following the  approval of  the Merger  Agreement and  the  UCU
Merger  by  the  stockholders  of UCU  (the  "UCU  Stockholders'  Approval" and,
together with the KCPL  Shareholders' Approval, the "Stockholders'  Approvals"),
and the satisfaction or waiver of the other conditions to the Mergers, including
obtaining  the requisite regulatory  approvals, (i) Sub will  be merged with and
into UCU, with UCU surviving in  the UCU Merger and (ii) immediately  thereafter
at  the Effective Time,  the UCU Surviving  Corporation will be  merged with and
into KCPL,  with KCPL  surviving (and  renamed as  Maxim) in  the  Consolidating
Merger.
 
    If the Stockholders' Approvals are obtained, and the other conditions to the
Mergers are satisfied or waived, the closing of the Mergers (the "Closing") will
take  place on the second  business day immediately following  the date on which
the last of the conditions referred to below under the caption "-- Conditions to
Each Party's Obligation  to Effect the  Mergers" is fulfilled  or waived, or  at
such other time and date as KCPL and UCU mutually agree (the "Closing Date").
 
    Subject  to  the  condition  that  the opinions  of  Merrill  Lynch  and DLJ
described under the caption "THE MERGERS -- Opinion of KCPL's Financial Advisor"
and "-- Opinion of UCU's Financial Advisor" shall not have been withdrawn,  KCPL
and UCU have agreed to call, give notice of, convene and hold a meeting of their
respective  stockholders as  soon as reasonably  practicable for  the purpose of
securing the Stockholders' Approvals.
 
    CONSUMMATION OF THE MERGERS.  The  Mergers will be consummated on the  terms
and  subject to the conditions set forth in the Merger Agreement, as a result of
which (i) as of the  UCU Effective Time, Sub will  be merged with and into  UCU,
with  UCU surviving  in the  UCU Merger and  (ii) immediately  thereafter at the
Effective Time, the UCU Surviving Corporation will be merged with and into KCPL,
with KCPL  surviving (and  renamed as  Maxim) in  the Consolidating  Merger.  In
addition, as of the UCU Effective Time, (i) each issued and outstanding share of
UCU  Common Stock (other  than shares of UCU  Common Stock owned  by KCPL or UCU
either directly or through a wholly-owned Subsidiary) will be converted into and
become one fully  paid and nonassessable  share of Maxim  Common Stock and  (ii)
each issued and outstanding share of Sub Common Stock will be converted into and
become  one fully paid and nonassessable share  of common stock, $0.01 par value
per share, of the UCU Surviving  Corporation. Each issued and outstanding  share
of KPCL Common Stock held by KCPL shareholders will remain outstanding after the
Mergers,  unchanged, as one share of Maxim  Common Stock. Based on the number of
shares of KCPL Common Stock and UCU  Common Stock outstanding as of the date  of
the  Merger Agreement, the holders  of KCPL Common Stock  and the holders of UCU
Common Stock will hold in the aggregate approximately 57% and 43%, respectively,
of the total  number of  shares of  Maxim Common  Stock outstanding  immediately
after the Effective Time.
 
                                       83
<PAGE>
    KCPL has agreed under the Merger Agreement to call for redemption before the
UCU  Effective Time all  of the outstanding  shares of each  series and class of
KCPL Preferred Stock at the applicable redemption prices therefor, together with
all dividends accrued and  unpaid through the  applicable redemption dates.  UCU
has  agreed  under  the Merger  Agreement  to  call for  redemption  all  of the
outstanding shares of UCU Preferred Stock, which is the only outstanding  series
or  class of preferred stock of  UCU, on March 3, 1997  or on such later date as
KCPL and UCU shall mutually agree. The redemption price therefor will be  $25.00
per  share of UCU Preferred Stock plus  all accrued and unpaid dividends through
the redemption date. It is  a condition to the closing  of the Mergers that  the
UCU  Preferred  Stock  and  KCPL  Preferred Stock  be  redeemed  before  the UCU
Effective Time.
 
    Pursuant to the Merger  Agreement, at the Effective  Time, (i) the  Restated
Articles  of  Consolidation  of  KCPL  as in  effect  immediately  prior  to the
Effective Time, and as  amended in respect  of clause (iii)  below, will be  the
Restated Articles of Consolidation of Maxim until thereafter amended as provided
by  law and such Restated Articles of  Consolidation, (ii) the Bylaws of KCPL as
in effect immediately prior to  the Effective Time will  be the Bylaws of  Maxim
until   thereafter  amended  as  provided  by  law,  the  Restated  Articles  of
Consolidation of Maxim and such by-laws, and (iii) KCPL will change its name  to
Maxim  or such other name  as KCPL and UCU shall  mutually agree. Subject to the
foregoing, the  additional  effects  of  the Consolidating  Merger  will  be  as
provided in the applicable provisions of the DGCL and the MGCL.
 
    EXCHANGE  OF CERTIFICATES.   As soon as practicable  after the UCU Effective
Time, the  Exchange  Agent  will  mail  to each  holder  of  record  of  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  Maxim Common Stock. 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  will be  entitled to  receive  a certificate  or certificates
representing that number of whole shares of Maxim Common Stock which such holder
has the right  to receive pursuant  to the provisions  of the Merger  Agreement.
Until surrendered, each Old Certificate will be deemed at any time after the UCU
Effective  Time to represent only  the right to receive  upon such surrender the
certificate representing Maxim Common Stock.
 
    The letter  of transmittal  may, at  the option  of Maxim,  provide for  the
ability  of a holder of one or more Old Certificates to elect that the shares of
Maxim Common Stock to be received be  issued in uncertificated form or to  elect
that  such shares  be credited  to an account  established for  the holder under
Maxim's dividend reinvestment and stock purchase plan.
 
    No dividends or other distributions declared or made after the UCU Effective
Time with  respect to  Maxim  Common Stock  with a  record  date after  the  UCU
Effective  Time will be paid to the holder of any unsurrendered Old Certificates
until such Old Certificates have been surrendered by such holder. Following such
surrender, subject to applicable law, there will be paid to such holder, without
interest, the  unpaid  dividends  and  distributions to  which  such  holder  is
entitled.
 
    HOLDERS  OF UCU  COMMON STOCK  SHOULD NOT  SEND IN  THEIR STOCK CERTIFICATES
UNTIL THEY RECEIVE A TRANSMITTAL FORM.
 
    HOLDERS OF  KCPL  COMMON  STOCK  WILL NOT  NEED  TO  SURRENDER  THEIR  SHARE
CERTIFICATES.  ISSUED AND OUTSTANDING  SHARES OF KPCL COMMON  STOCK HELD BY KCPL
SHAREHOLDERS WILL  REMAIN OUTSTANDING  AFTER  THE MERGERS  BUT ARE  REFERRED  TO
HEREIN AS MAXIM COMMON STOCK TO REFLECT KCPL'S NAME CHANGE TO MAXIM.
 
SUBSIDIARIES AND JOINT VENTURES
 
    The  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 or UCU,  as the case  may be. The Merger
Agreement also defines "Joint Venture" to mean specified joint ventures of  KCPL
and  UCU,  as the  case may  be. The  covenants of  KCPL and  UCU in  the Merger
Agreement
 
                                       84
<PAGE>
apply  to  the  parties  themselves  and  their  Subsidiaries.  Certain  of  the
representations  and warranties of KCPL and UCU in the Merger Agreement apply to
the parties, their Subsidiaries and their Joint Ventures.

    The 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  Mergers in accordance with  the
terms of the Merger Agreement.
 
NO SOLICITATION OF TRANSACTIONS
 
    The  Merger  Agreement provides  that neither  KCPL nor  UCU will,  and that
neither will  authorize or  permit any  of its  officers, directors,  employees,
accountants, counsel, investment bankers, financial
 
                                       86
<PAGE>
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 Merger Agreement, a respective party may (i) at any time  prior
to  the time the parties'  stockholders shall have voted  in respect of the KCPL
Shareholders' Approval or the  UCU Stockholders' Approval, as  the case may  be,
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  Mergers  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  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
Merger Agreement pursuant to the provisions of Section 9.1(e) or 9.1(f) thereof,
as   applicable  (which  provisions  are  described  in  clause  (e)  under  "--
Termination," below). 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 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.
 
MAXIM BOARD OF DIRECTORS
 
    The Merger Agreement provides  that at the Effective  Time, the Maxim  Board
will  consist of 18 persons, nine of whom will be the then existing directors of
KCPL prior to  the Effective Time  and nine of  whom will be  designated by  UCU
prior  to  the Effective  Time. If,  prior to  the Effective  Time, any  of such
designees declines or is unable to serve, the party that designated such  person
will designate another person to serve in such person's stead. As of the date of
this  Joint Proxy Statement/Prospectus, UCU has  not decided who, in addition to
Mr. Green, will be designated  to serve on the  Maxim Board after the  Effective
Time.

DIRECTORS' AND OFFICERS' INDEMNIFICATION
 
    The  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  Effective  Time, Maxim  will,  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
Effective  Time, 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 Effective Time (and whether asserted  or
claimed prior to, at or after the Effective Time) 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 Merger  Agreement. In the event  of any such loss,  expense,
claim,  damage or liability (whether or  not arising before the Effective Time),
(i) Maxim will pay the reasonable fees  and expenses of counsel selected by  the
Indemnified  Parties, which  counsel must  be reasonably  satisfactory to Maxim,
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 MGCL, (ii)  Maxim
will  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 MGCL, the Restated Articles of
Consolidation or Bylaws of  Maxim will be made  by independent counsel  mutually
acceptable  to Maxim  and the Indemnified  Party; provided,  however, that Maxim
will not  be liable  for any  settlement effected  without its  written  consent
(which  consent must not be unreasonably withheld). The 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 Merger  Agreement requires that for  a period of six  years
after  the Effective Time, Maxim will cause  to be maintained in effect policies
of directors' and officers' liability insurance  maintained by KCPL and UCU  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  Maxim will  not  be required  to expend  in  any year  an amount
exceeding 200% of the annual aggregate  premiums currently paid by KCPL and  UCU
for  such insurance.  If the annual  premiums of such  insurance coverage exceed
such amount, Maxim will be obligated to  obtain a policy with the best  coverage
available,  in  the reasonable  judgment  of the  Maxim  Board, for  a  cost not
exceeding such amount. The  Merger Agreement also provides  that to the  fullest
extent  permitted  by law,  from and  after  the Effective  Time, all  rights to
indemnification existing  in  favor  of the  employees,  agents,  directors  and
officers  of KCPL, UCU  and their respective Subsidiaries  with respect to their
activities as such prior to the Effective Time, as provided in their  respective
articles  of  incorporation  and  by-laws  in effect  on  January  19,  1996, or
otherwise in  effect on  January 19,  1996, will  survive the  Mergers and  will
continue  in full force and effect for a  period of not less than six years from
the Effective Time.
 
CONDITIONS TO EACH PARTY'S OBLIGATION TO EFFECT THE MERGERS
 
    The respective obligations of KCPL and UCU to effect the Mergers are subject
to the  following conditions:  (a) the  approval of  the Share  Issuance by  the
shareholders  of KCPL and the  UCU Merger by the  stockholders of UCU shall have
been obtained;  (b) no  temporary restraining  order, preliminary  or  permanent

which do not impose terms or
 
                                       88
<PAGE>
conditions  that could reasonably be expected to have a material adverse effect;
(f) the receipt by each of KCPL and UCU of letters from their independent public
accountants stating  that the  Mergers will  qualify as  a  pooling-of-interests
transaction  under generally  accepted accounting principles  and applicable SEC
regulations; (g) with respect to  each of KCPL and  UCU, the performance in  all
material respects of all obligations of the other party required to be performed
under the Merger Agreement, including the redemption of the KCPL Preferred Stock
and  UCU Preferred Stock, as the  case may be; (h) with  respect to each of KCPL
and UCU, the accuracy of the  representations and warranties of the other  party
set forth in the Merger Agreement as of January 19, 1996 (except with respect to
representations  and warranties made as of May 20, 1996, which shall be accurate
as of such date) and as  of the Closing Date (except  in all cases as would  not
reasonably  be likely to  result in a  material adverse effect);  (i) KCPL's and
UCU's having  received  officers'  certificates from  each  other  stating  that
certain  conditions set forth  in the Merger Agreement  have been satisfied; (j)
with respect to  each of KCPL  and UCU,  there having been  no material  adverse
effect  on the business,  assets, financial condition,  results of operations or

with  respect to each of KCPL and UCU, the receipt by the other party of certain
material third-party consents; and (m) with respect to UCU, the receipt by  KCPL
of  letter  agreements  relating  to  trading  in  securities  of  KCPL  and UCU
(substantially in the form attached as an exhibit to the Merger Agreement), duly
executed by each affiliate of UCU.
 
    In addition, the  Merger Agreement provides  that it is  a condition to  the
obligation  of KCPL to hold  the KCPL Meeting that  the opinion of Merrill Lynch
attached hereto as Annex B shall not have been withdrawn, and it is a  condition
to  the  obligation of  UCU to  hold the  UCU  Meeting that  the opinion  of DLJ
attached hereto as Annex C shall not have been withdrawn.
 
    At any time  prior to the  UCU Effective  Time, to the  extent permitted  by
applicable  law, the conditions to KCPL's or UCU's obligations to consummate the
Mergers 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. See "-- Amendment and Waiver."
 
BENEFIT PLANS
 
    The Merger Agreement provides that KCPL and UCU have agreed to cooperate and
agree upon the employee benefit plans and programs to be provided by Maxim,  and
that each participant of any KCPL benefit plan or UCU benefit plan shall receive
credit  for purposes of  eligibility to participate,  vesting and eligibility to
receive benefits under any benefit plan of  Maxim or any of its subsidiaries  or
affiliates  that replaces  a KCPL  benefit plan  or UCU  benefit plan; provided,
however, that  such crediting  of service  shall not  operate to  duplicate  any
benefit  to  any  such participant  or  the  funding for  any  such  benefit. In
addition, the UCU Supplemental Contributory Retirement Plan shall be revised  to
provide  that references to UCU Common Stock shall instead refer to Maxim Common
Stock.
 
    Upon the  consummation of  the Mergers,  no additional  obligations will  be
incurred  under the existing short-term incentive compensation plans of KCPL and
UCU. Subject to shareholder approval thereof at the KCPL Meeting, the Maxim  MIC
Plan  will become effective at  the Effective Time. The  Maxim MIC 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 Maxim
Compensation Committee. With respect to those  participants in the new plan  who
are,  or  who the  Maxim  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. See  "APPROVAL
OF MAXIM PLANS -- Maxim MIC Plan" and Annex E.
 
    Following   the  implementation  of  the  Maxim  Stock  Incentive  Plan,  no
additional awards will be made under the existing stock incentive plans of  KCPL
and UCU. Subject to shareholder approval
 
                                       89
<PAGE>
thereof  at  the  KCPL  Meeting,  the Maxim  Stock  Incentive  Plan  will become
effective at the Effective Time. The Maxim Stock Incentive Plan provides for the
grant of stock options, SARs, restricted stock and such other awards based  upon
Maxim Common Stock as the Maxim Compensation Committee may determine, subject to
shareholder approval of the Maxim Stock Incentive Plan. Maxim intends to reserve
9,000,000   shares  of  Maxim  Common  Stock   for  issuance  under  this  plan.
Accordingly, the Maxim Stock Incentive  Plan is being submitted to  shareholders
for  approval. See "APPROVAL OF  MAXIM PLANS -- Maxim  Stock Incentive Plan" and
Annex D.
 
    At the Effective Time, (i) an option to purchase shares of UCU Common  Stock
under  the existing stock  incentive plans of  UCU (each, a  "UCU Stock Option")
will constitute an option to acquire, on the same terms and conditions  (subject
to  the adjustments necessary  to give effect  to the Mergers),  shares of Maxim
Common Stock based on  the same number  of shares of Maxim  Common Stock as  the
holder  of such UCU Stock Option would have been entitled to receive pursuant to
the Mergers had such holder exercised  such option in full immediately prior  to
the  Effective Time  and (ii)  each other  outstanding award  under the existing
stock incentive plans  of UCU  (each, a "UCU  Stock Award")  will constitute  an
award  based upon the same number of shares  of Maxim Common Stock as the holder
of such UCU  Stock Award would  have been  entitled to receive  pursuant to  the
Mergers  had such holder been the  owner, immediately before the Effective Time,
of the shares of UCU  Common Stock on which such  UCU Stock Award is based,  and
otherwise  on the  same terms  and conditions as  governed such  UCU Stock Award
immediately before the Effective Time. See "THE MERGERS -- Maxim Plans."
 
CERTAIN EMPLOYMENT AGREEMENTS AND WORKFORCE MATTERS
 
    Subject to  certain  provisions  in  the Merger  Agreement,  Maxim  and  its
Subsidiaries   have  agreed  to  honor,  without  modification,  all  contracts,
agreements, collective bargaining  agreements and  commitments of  KCPL and  UCU
prior  to the date of  the Merger Agreement that apply  to any current or former
employee or  current  or former  director  of  the parties  hereto.  Subject  to
applicable  collective  bargaining  agreements,  for  a  period  of  three years
following the  Effective  Time,  any  reductions  in  workforce  in  respect  of
employees  of Maxim shall be made on  a fair and equitable basis, without regard
to whether employment was with KCPL or  the KCPL Subsidiaries or UCU or the  UCU
Subsidiaries,  and  any  employee  whose  employment  is  terminated  or  job is
eliminated by  Maxim or  any of  its Subsidiaries  during such  period shall  be
entitled to participate on a fair and equitable basis in the job opportunity and
employment  placement programs offered by Maxim  or any of its Subsidiaries. Any
workforce reductions carried out following the  Effective Time by Maxim and  its
Subsidiaries  shall  be  done  in  accordance  with  all  applicable  collective
bargaining  agreements  and  all  laws  and  regulations  governing  the  Worker
Adjustment   and  Retraining   Notification  Act   and  regulations  promulgated
thereunder, and any comparable state or local law.
 
TERMINATION
 
    The Merger Agreement  may be  terminated at any  time prior  to the  Closing
Date,  whether before or  after the Stockholders'  Approvals have been obtained:
(a) by mutual written consent of the KCPL Board and the UCU Board; (b) by either
KCPL or UCU  if (i)  the other  party (x)  has breached  certain agreements  and
covenants relating to dividends or issuance of securities but only to the extent
such  agreements and  covenants apply  to KCPL or  UCU and  not their respective
Subsidiaries, or (y) has breached any representations, warranties, covenants  or
agreements  set forth in the Merger Agreement, which breaches individually or in
the aggregate would result in  a material adverse effect  on such party and,  in
the  case of either (x) or (y), the breach has not been cured within 20 business
days following  the  breaching party's  receipt  of  notice of  such  breach  or
adequate  assurance of such cure  is not given by or  on behalf of the breaching
party within such  20 business-day period,  (ii) the Board  of Directors of  the
other  party or any  committee thereof (A)  withdraws or modifies  in any manner
adverse to such party its approval or recommendation of the Merger Agreement  or
the  Mergers, (B)  fails to reaffirm  such approval or  recommendation upon such
party's request, (C) approves or
 
                                       90
<PAGE>
recommends  any acquisition  of the  other party  or a  material portion  of its
assets or any tender offer for the other party's capital stock, in each case  by
a  party other than such party or any  of its affiliates or (D) resolves to take
any of the actions specified  in clause (A), (B) or  (C), or (iii) any state  or
federal  law, order,  rule or  regulation is  adopted or  issued, which  has the
effect, as supported by the written opinion of outside counsel of such party, of
prohibiting the Mergers, or any court  of competent jurisdiction in the U.S.  or
any   state  shall  have  issued  an   order,  judgment  or  decree  permanently
restraining, enjoining or  otherwise prohibiting  the Mergers,  and such  order,
judgment  or decree shall have become final  and nonappealable; (c) by any party
thereto, if the Effective Time shall not have occurred on or before December 31,
1997 (which date will be extended to December 31, 1998 if the required statutory
approvals and third-party consents have not been obtained by December 31,  1997,
but  all other conditions to the Closing  shall be fulfilled or shall be capable
of being fulfilled); provided, however, that such right to terminate the  Merger
Agreement  will  not be  available to  any  party whose  failure to  fulfill any
obligation under the Merger Agreement has been the cause of, or resulted in, the
failure of the Effective Time  to occur on or before  December 31, 1997; (d)  by
any  party thereto, if the Stockholders' Approvals shall not have been obtained;
(e) by KCPL or UCU, upon five days' prior notice to the other party and prior to
approval of the  Merger Agreement by  the other party's  stockholders, if, as  a
result  of an Acquisition Proposal by a person other than the other party or any
of its affiliates, the Board of Directors of such party determines in good faith
after considering applicable provisions  of state law, on  the basis of oral  or
written  advice of outside counsel, that  acceptance of the Acquisition Proposal
is necessary for such Board of Directors to act in a manner consistent with  its
fiduciary duties under applicable law; provided, however, that (i) such Board of
Directors  shall  have concluded  in  good faith,  after  considering applicable
provisions of state law and after giving effect to all concessions which may  be
offered  by the other party pursuant to clause  (ii) below, 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 (ii) prior to any such termination, such party will, and will
cause  its respective financial and legal  advisors to, negotiate with the other
party to  make  such adjustments  in  the terms  and  conditions of  the  Merger
Agreement   as  would  enable  such  party  to  proceed  with  the  transactions
contemplated thereby on such adjusted terms.
 
    In the event of termination of the Merger Agreement by either KCPL or UCU as
provided above, there will be no liability  or obligation on the part of  either
KCPL  or UCU or their respective officers  or directors thereunder other than to
hold in strict  confidence all documents  furnished to the  other in  accordance
with the Confidentiality Agreement; to pay certain fees and expenses pursuant to
certain  specified provisions of the Merger  Agreement described below under the
captions "-- Termination  Fees" and  "-- Expenses"  and to  comply with  certain
other specified provisions of the Merger Agreement.
 
TERMINATION FEES
 
    The  Merger Agreement provides that if the Merger Agreement is terminated at
such time as  it is  terminable by either  (but not  both) of KCPL  and UCU  for
breaches of any representations or warranties contained in the Merger Agreement,
or of agreements and covenants contained in the Merger Agreement pursuant to the
provisions of the Merger Agreement described in clause (b) (i) under the caption
"--  Termination" above,  then the  breaching party  will pay  the non-breaching
party a fee equal  to $10 million  in cash, minus amounts  previously paid by  a
breaching  party  in respect  of termination,  provided however,  if termination
results from a  willful breach, the  breaching party will  pay the  nonbreaching
party  a fee equal to $35 million in cash minus any amounts previously paid by a
breaching party  in respect  of termination.  If at  the time  of the  breaching
party's  willful  breach, pursuant  to the  provisions  of the  Merger Agreement
described in  such clause  (b) (i)  there  shall have  been previously  made  an
Acquisition  Proposal (whether or not such  Acquisition Proposal shall have been
rejected or withdrawn prior to the time of termination) involving the  breaching
party  or  one of  its  affiliates, and  within two  and  one-half years  of any
termination by  the non-breaching  party, the  breaching party  or an  affiliate
becomes a Subsidiary of such offeror or of an
 
                                       91
<PAGE>
affiliate  thereof, or accepts  a written offer to  consummate or consummates an
Acquisition Proposal  with such  third  party or  affiliate thereof,  then  such
breaching party (jointly and severally with its affiliates), upon the signing of
a  definitive agreement relating to such an Acquisition Proposal, or, if no such
agreement is signed, then at the closing (and as a condition to the closing)  of
such breaching party becoming such a Subsidiary or of such Acquisition Proposal,
shall  pay to the non-breaching party an  additional fee equal to $58 million in
cash minus any such amounts  as may have previously  been paid by the  breaching
party due to a termination.
 
    If  the Merger  Agreement is terminated  because UCU's  stockholders fail to
approve the UCU  Merger, in  the case  of UCU,  or KCPL's  shareholders fail  to
approve  the Share  Issuance, in the  case of KCPL,  such party will  pay to the
other a fee  of $5 million;  provided that such  fee shall be  reduced (but  not
below zero) by any termination fee previously paid.
 
    The  Merger  Agreement also  requires payment  of a  termination fee  of $58
million in  cash minus  any amounts  previously  paid by  the Target  Party  (as
defined below in this paragraph) to the other party, if (i) the Merger Agreement
is  terminated (A) as a result of the acceptance by such party of an Acquisition
Proposal pursuant to the provisions of the Merger Agreement described in  clause
(e)  under the caption  "-- Termination" above,  (B) following a  failure of the
stockholders of such party to grant  the KCPL Shareholders' Approval or the  UCU
Stockholders'  Approval, as the case may be, or  (C) as a result of such party's
material failure to  convene a stockholder  meeting, distribute proxy  materials
and,  subject to  its Board  of Directors'  fiduciary duties,  recommend the UCU
Merger to its stockholders, in the case of UCU, or recommend the approval of the
Share Issuance, in the  case of KCPL;  (ii) at the time  of such termination  or
prior  to the  meeting of  such party's stockholders,  there shall  have been an
Acquisition Proposal involving such party or  any of its affiliates (whether  or
not this Acquisition Proposal shall have been rejected or withdrawn prior to the
time  of  termination); and  (iii) within  two  and one-half  years of  any such
termination described in  clause (i) above,  such party or  such affiliate  (the
"Target  Party") becomes  a Subsidiary  of such offeror  or accepts  an offer to
consummate or  consummates  an Acquisition  Proposal  with such  offeror  of  an
affiliate,  then the Target  Party (jointly and  severally with its affiliates),
upon the  signing of  a definitive  agreement relating  to such  an  Acquisition
Proposal,  or, if  no such agreement  is signed, then  at the closing  (and as a
condition to the closing) of such party's becoming such a Subsidiary or of  such
Acquisition Proposal.
 
    The  Merger Agreement further provides  that all termination fees constitute
liquidated damages  and  not  penalties  and  that,  notwithstanding  any  other
provision  of  the  Merger  Agreement,  if one  party  should  fail  to  pay any
termination fee due, in addition to payment of such amount, the defaulting party
will pay the costs and expenses in  connection with any action taken to  collect
payment, together with interest on the amount of any unpaid termination fee.
 
EXPENSES
 
    Except  as set  forth above, all  costs and expenses  incurred in connection
with the Merger Agreement and the transactions contemplated thereby will be paid
by the  party incurring  the expense,  except that  those expenses  incurred  in
connection with printing and filing of the Registration Statement, of which this
Joint  Proxy Statement/Prospectus forms  a part, will be  shared equally by KCPL
and UCU.
 
AMENDMENT AND WAIVER
 
    The Merger Agreement may be amended by the Board of Directors of the parties
thereto at any time before or after approval thereof by the stockholders of KCPL
and UCU  and prior  to the  Effective Time,  but after  such approvals  no  such
amendment will alter or change the amount or kind of shares, rights or manner of
exchange  of such shares, or alter or change  any of the terms and conditions of
the Merger Agreement  if any  of the  alterations or  changes, alone  or in  the
aggregate,  would  materially adversely  affect the  rights  of holders  of KCPL
Common Stock or UCU Common Stock,  except for alterations or changes that  could
otherwise  be adopted by  the Maxim Board  without the further  approval of such
stockholders. At any time prior  to the UCU Effective  Time, the parties to  the
Merger  Agreement may  by a  signed written  agreement extend  the time  for the
performance of any of the
 
                                       92
<PAGE>
obligations or other acts of the  other parties thereto, waive any  inaccuracies
in  the  representations and  warranties contained  therein  or in  any document
delivered pursuant thereto, and waive compliance  with any of the agreements  or
conditions contained in the Merger Agreement to the extent permitted by law.
 
CONFIDENTIALITY AGREEMENT
 
    KCPL and UCU have agreed pursuant to the Confidentiality Agreement that, for
a three-year period commencing on November 28, 1995, unless and until such party
shall  have received the  prior written approval  of a majority  of the Board of
Directors of  the  other  party,  neither  party,  nor  its  representatives  or
affiliates,  will directly or  indirectly (a) acquire, agree  to acquire or make
any proposal  to  acquire any  securities  of the  other  party or  any  of  its
subsidiaries, any warrant or option to acquire any such securities, any security
convertible  into or exchangeable for any such  securities or any other right to
acquire any  such securities,  (b) seek  or propose  any merger,  consolidation,
business  combination, tender or  exchange offer, sale or  purchase of assets or
securities, dissolution, liquidation, restructuring, recapitalization or similar
transactions of or  involving the other  party or any  of its subsidiaries,  (c)
make,  or in any way  participate in, any "solicitation"  of proxies or consents
with respect to any securities of the other party or any of its subsidiaries, or
seek to  advise or  influence  any person  with respect  to  the voting  of  any
securities  of the other party or any of  its subsidiaries, (d) form, join or in
any way participate in a "group" (within the meaning of Section 13(d)(3) of  the
Exchange Act) with respect to any voting securities of the other party or any of
its subsidiaries, (e) otherwise act, alone or in concert with others, to seek to
control  or  influence, in  any manner,  the management,  Board of  Directors or
policies of the other party or any of its subsidiaries, (f) have any discussions
or enter into any  arrangements, understandings or  agreements with, or  advise,
finance,  assist or encourage, any  other persons in connection  with any of the
foregoing, or (g)  make any  publicly disclosed  proposal regarding  any of  the
foregoing.
 
                       DESCRIPTION OF MAXIM COMMON STOCK
 
    The  following  statements  contain, in  summary  form,  certain information
relating to KCPL Common  Stock (which herein is  termed Maxim Common Stock  when
referring  to KCPL Common  Stock after the  Mergers). They do  not purport to be
complete or to  reflect or  give effect  to statutory  law and  are intended  to
outline  the information  presented in general  terms only.  Such statements are
subject to  the  detailed  provisions  of the  KCPL  Charter,  which  after  the
Effective  Time will be renamed  and become the Maxim  Charter, and the detailed
provisions of the KCPL  Bylaws, which after the  Effective Time will be  renamed
and become the Maxim Bylaws.
 
DIVIDEND RIGHTS AND RESTRICTIONS
 
    Subject  (i) to the preferential dividends  of the Maxim Preferred Stock (as
defined herein), (ii)  to certain provisions  for the protection  of holders  of
Maxim  Preferred Stock,  and (iii) to  other restrictive  provisions referred to
below, dividends  may  be  paid on  shares  of  Maxim Common  Stock  from  funds
available for that purpose, when and as declared by the Maxim Board. Pursuant to
the  Merger Agreement, KCPL is obligated to redeem all outstanding shares of the
KCPL Preferred Stock  before the Effective  Time. However, Maxim  will have  the
ability  to issue preferred stock ("Maxim  Preferred Stock") after the Effective
Time.
 
    No dividends may  be declared or  paid on  Maxim Common Stock  and no  Maxim
Common Stock may be purchased or redeemed or otherwise retired for consideration
(a)  unless  all  past and  current  dividends  on shares  of  outstanding Maxim
Preferred Stock have been paid  or set apart for payment  and (b) except to  the
extent of retained earnings.
 
    In  addition, cash  dividends on and  the acquisition of  Maxim Common Stock
will be restricted by provisions of the Indenture of Michigan Gas Utilities,  an
operating division of UCU, dated as of July 1, 1951, as amended and supplemented
(the  "MGU  Indenture"),  securing  a portion  of  Maxim's  mortgage  bonds. The
obligations under the  MGU Indenture were  assumed by  UCU and will  be, at  the
Effective  Time, assumed by Maxim. Under  the most restrictive of the provisions
contained in the
 
                                       93
<PAGE>
MGU Indenture, Maxim may not declare or pay any dividend (other than a  dividend
payable in shares of its capital stock), whether in cash, stock or otherwise, or
make  any other  distribution, on or  with respect  to any class  of its capital
stock, or purchase or otherwise acquire any  shares of any class of its  capital
stock  if, after giving effect  thereto, the sum of  (i) the aggregate amount of
all dividends declared and  all other distributions  made (other than  dividends
declared  or distributions made in shares of its capital stock) on shares of its
capital stock, of  any class,  subsequent to December  31, 1984,  plus (ii)  the
excess,  if any, of the amount applied to or set apart for the purchase or other
acquisition of any  shares of  its capital stock,  of any  class, subsequent  to
December 31, 1984, over such amounts as shall have been received by Maxim as the
net  cash  proceeds of  sales  of shares  of its  capital  stock, of  any class,
subsequent to December 31, 1984, would exceed the sum of the net income of Maxim
since January 1, 1985, plus $50 million. In addition, Maxim may not declare such
dividends unless it maintains a tangible net worth of at least $250 million  and
the  aggregate principal amount of its  outstanding indebtedness does not exceed
70% of its capitalization. On a pro forma basis and as of the date of this Joint
Proxy  Statement/Prospectus,  none  of   Maxim's  retained  earnings  would   be
restricted  as  to payment  of cash  dividends on  its capital  stock as  of the
Effective Time pursuant to the MGU Indenture.
 
    In addition, the cash payment of dividends on, and the acquisition of, Maxim
Common Stock will be restricted by provisions of the Indenture of UCU, dated  as
of  June  1,  1995, relating  to  UCU's  8 7/8%  Junior  Subordinated Deferrable
Interest Debentures, Series  A, due 2025,  which provide that  in the event  UCU
elects to defer interest on such debentures, UCU may not declare any dividend on
or  acquire any  shares of  its capital stock  during such  deferral period. The
obligations of UCU under this  Indenture will be, prior  to or at the  Effective
Time, assumed by Maxim.
 
VOTING RIGHTS
 
    The holders of Maxim Common Stock exclusively possess full voting powers for
the  election of directors (who may be voted for cumulatively) and for all other
purposes, except (a) as by statute otherwise mandatorily provided, (b) that  the
consent  of  specified percentages  of holders  of  outstanding shares  of Maxim
Preferred Stock is required to authorize certain actions which may affect  their
interest, and (c) that if at any time dividends on any of the outstanding shares
of  certain series  of Maxim Preferred  Stock shall  be in default  in an amount
equivalent to four or more full quarterly dividends, the holders of  outstanding
shares  of such  series, voting  as a  single class,  shall be  entitled (voting
cumulatively) to elect the smallest number of directors necessary to  constitute
a  majority of the full Maxim Board,  which right shall continue in effect until
all dividend arrearages shall have been paid.
 
LIQUIDATION RIGHTS
 
    In the event of voluntary dissolution  or liquidation of Maxim, after  there
shall  have been paid to  or set aside for the  holders of shares of outstanding
Maxim  Preferred  Stock  the  full  preferential  amounts  to  which  they   are
respectively  entitled, the holders of outstanding  shares of Maxim Common Stock
shall be entitled to receive pro rata, according to the number of shares held by
each, the remaining assets of Maxim available for distribution.
 
PREEMPTIVE RIGHTS
 
    No holder of  outstanding shares of  Maxim Common Stock  has any  preemptive
right  to subscribe for or acquire any shares  of stock or any securities of any
kind issued by Maxim.
 
LIABILITY TO ASSESSMENT
 
    The outstanding shares of Maxim Common Stock when issued in accordance  with
the terms of the Merger Agreement will be fully paid and nonassessable.

CERTAIN ANTI-TAKEOVER PROVISIONS
 
    The  Maxim Charter  and Maxim  Bylaws contain  provisions that  may have the
effect of discouraging persons from acquiring large blocks of Maxim Common Stock
or delaying or preventing  a change in  control of Maxim.  For a description  of
these provisions, see "COMPARISON OF STOCKHOLDERS' RIGHTS."
 
                       COMPARISON OF STOCKHOLDERS' RIGHTS
 
GENERAL
 
    KCPL  is incorporated in the  State of Missouri, and  UCU is incorporated in
the State of Delaware. UCU stockholders, whose rights are currently governed  by
Delaware  law (including the  DGCL), the UCU  Charter and the  UCU Bylaws, will,
upon consummation of the  Mergers, become shareholders of  KCPL (which is to  be
renamed Maxim at the Effective Time). After such time, their rights will then be
governed  by Missouri law (including the MGBCL), the Maxim Charter and the Maxim
Bylaws.
 
    Certain differences, including all material differences, that may affect the
rights and interests of stockholders of Maxim and UCU are set forth below.  This
summary  is not  intended to  be an  exhaustive or  detailed description  of the
provisions discussed. It is qualified in its entirety by reference to the MGBCL,
DGCL, the Maxim Charter, the Maxim Bylaws, the UCU Charter and the UCU Bylaws.
 
NUMBER OF DIRECTORS
 
    Under the  Maxim Charter  and the  Maxim  Bylaws, the  Maxim Board  must  be
comprised of at least three directors, the exact number to be fixed by the Maxim
Bylaws.  The Maxim Bylaws  presently provide that the  exact number of directors
will be nine, but the  Maxim Bylaws may be amended  by the KCPL Board to  change
such  number.  See "--  Amendment  of Bylaws."  KCPL  has agreed  in  the Merger
Agreement to  take such  action  as may  be necessary  to  cause the  number  of
directors  comprising the Maxim  Board at the  Effective Time to  be 18 persons.
Under the UCU Charter and the UCU Bylaws, the UCU Board must be comprised of  at
least  three  directors,  the  exact  number to  be  fixed  by  the  UCU Bylaws.
Currently, the UCU  Board consists of  nine directors. Under  the UCU Bylaws,  a
majority vote of the UCU Board is required to alter the size of the UCU Board.
 
CLASSIFIED BOARD OF DIRECTORS
 
    The  Maxim Board is not  classified, and the Maxim  Bylaws provide that each
director will be elected annually  to a one-year term.  The UCU Charter and  UCU
Bylaws  provide for  the UCU  Board to  be divided  into three  classes. At each
annual meeting  of  stockholders  of UCU,  one  class  is to  be  elected  to  a
three-year term.
 
VACANCIES ON THE BOARD OF DIRECTORS
 
    Under  the Maxim Charter and the Maxim  Bylaws, vacancies on the Maxim Board
may be filled by  the designee of  a majority of the  directors then in  office,
even if less than a quorum. A director so designated will hold office for a term
coinciding  with  the term  of  the class  to  which such  director  is elected.
Vacancies on the UCU Board are filled in the same manner.
 
REMOVAL OF DIRECTORS
 
    The Maxim Charter and the Maxim Bylaws  are silent as to the removal of  any
director,  but, under the MGBCL, one or more directors or the entire Maxim Board
may be removed, with  or without cause,  at a meeting of  the shareholders by  a
vote  of the  holders of  a majority  of the  shares then  entitled to  vote. In
addition, if less than the  entire Maxim Board is to  be removed, no one of  the
directors  may  be  removed if  the  votes  cast against  his  removal  would be
sufficient to elect him if then cumulatively voted at an election of the  entire
Maxim Board. The UCU Charter provides that directors of UCU may be removed, with
or  without cause,  by a  majority of  the shares  then entitled  to vote  at an
election of directors  cast at  a meeting of  the stockholders  called for  that
purpose.  If less than  the entire UCU Board  is to be  removed, however, no one
director may  be  removed  if  the  votes cast  against  his  removal  would  be
sufficient  to elect him if then cumulatively  voted at an election of the class
of directors of which  he is a  member. The UCU  Charter further provides  that,
notwithstanding the foregoing or the
 
                                       95
<PAGE>
fact  that the law may specify a lesser  percentage, the entire UCU Board may be
removed only by an affirmative vote of holders of at least 80% of the shares  of
outstanding  UCU capital  stock entitled  to vote  generally in  the election of
directors cast at a meeting of the stockholders called for that purpose.
 
VOTING/CUMULATIVE VOTING
 
    The Maxim  Bylaws  provide for  cumulative  voting in  connection  with  the
election of directors and otherwise provide that each outstanding share entitled
to vote under the Maxim Charter is entitled to one vote on each matter submitted
to  a shareholder  vote. The  UCU Charter  and the  UCU Bylaws  also provide for
cumulative voting  in  connection  with  the  election  of  directors  and  also
otherwise  provide that each  outstanding share entitled to  vote is entitled to
one vote on each matter submitted to a stockholder vote. Cumulative voting means
that in electing directors, each stockholder has the right to cast as many votes
in the aggregate as equals the number of shares held multiplied by the number of
directors to be elected at the election.
 
    The Maxim Bylaws  state that  unless required  otherwise by  law, the  Maxim
Charter  or the  Maxim Bylaws, issues  brought before a  meeting of shareholders
will, except with respect to the election of directors, be decided by a vote  of
the  holders of a majority  of the shares represented  and entitled to vote. The
UCU Bylaws contain a similar provision.
 
SPECIAL MEETINGS; STOCKHOLDER ACTION BY WRITTEN CONSENT
 
    The Maxim Bylaws state that, in general, special shareholders' meetings  may
only  be called by the Chairman of the Maxim Board, by the President of Maxim or
at the written request of a majority  of the Maxim Board. The Maxim Bylaws  also
state  that unless otherwise provided by law or in the Maxim Charter, any action
required to be taken by shareholders may be taken without a meeting if a consent
in writing, stating the action taken, is signed by all shareholders entitled  to
vote  on  the matter.  The UCU  Charter and  the UCU  Bylaws state  that special
meetings of UCU stockholders may be called by the President, the Vice President,
a majority of the UCU Board and holders of at least one-fifth of all outstanding
shares entitled  to vote  at such  meeting.  Under the  UCU Charter,  no  action
permitted  or required to be taken at a special or annual meeting of the holders
of UCU Common  Stock may be  taken by their  written consent in  lieu of such  a
meeting.
 
INDEMNIFICATION/LIMITATION OF LIABILITY
 
    The  MGBCL  and the  DGCL  permit indemnification  on  substantially similar
terms. A corporation may indemnify  any person made or  threatened to be made  a
party  to any  legal proceeding,  including any suit  by or  in the  name 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 in any capacity with respect to another enterprise, against expenses
and  other  amounts reasonably  incurred by  him in  connection with  such legal
proceeding if he acted in good faith  and in a manner he reasonably believed  to
be in or not opposed to the best interests of the corporation, and, with respect
to  any criminal proceeding, had no reasonable  cause to believe his conduct was
unlawful. The  foregoing  notwithstanding, no  indemnification  may be  made  in
respect  of any claim brought by  or in the name of  the corporation as to which
such person is adjudged to be liable  to the corporation unless and only to  the
extent  that a proper court determines that  in view of all the circumstances of
the case, such person  is fairly and reasonably  entitled to indemnity for  such
expenses  that  the court  deems proper.  These  indemnification rights  are not
exclusive of any  other rights to  which the person  seeking indemnification  is
entitled  and do not limit a corporation's right to make further indemnification
as allowed by law.
 
    The Maxim Charter  provides that  it will  indemnify to  the fullest  extent
permitted  by the MGBCL  any person made or  threatened to be made  a party to a
legal proceeding by reason  of the fact  that the person is  or was a  director,
officer  or employee of Maxim, or is or was serving at the request of Maxim as a
director, officer  or  employee  of another  enterprise,  against  all  expense,
liability  or  loss  (including  attorneys'  fees  and  judgments)  actually and
reasonably incurred  by such  person.  The Maxim  Board  has the  discretion  to
indemnify  agents of Maxim under similar terms. These indemnification rights are
not exclusive of  any other rights  to which the  person is entitled  by law  or
under any other Maxim
 
                                       96
<PAGE>
authorizations.  Maxim may, without shareholder  approval, provide its officers,
directors and  employees with  greater indemnification  than the  MGBCL  offers,
provided  that such  further indemnity  will not  be offered  to a  person whose
conduct was finally adjudged to  have been knowingly fraudulent or  deliberately
dishonest, or to have constituted willful misconduct.
 
    The  UCU Charter contains a provision that eliminates the personal liability
of UCU's directors to UCU or its stockholders for monetary damages for breach of
fiduciary duty to the fullest extent permitted  by the DGCL. A provision in  the
UCU  Bylaws entitles  officers and  directors to  be indemnified  by UCU against
costs and  expenses,  attorneys' fees,  judgments,  fines and  amounts  paid  in
settlement that are actually and reasonably incurred in connection with any such
action, suit or proceeding, including actions brought by or in the right of UCU,
to  which such persons are made  or threatened to be made  a party, by reason of
their being a  director or  officer of  UCU. Such  right, however,  may only  be
authorized  by (i) a  majority vote of  a quorum of  disinterested directors, or
(ii) if such quorum is not obtainable  or, if obtainable, a majority thereof  so
directs,  by independent  legal counsel  in a written  opinion, or  (iii) by the
stockholders  of   UCU,   upon  a   determination   that  the   person   seeking
indemnification  acted  in  good faith  and  in  the manner  that  he reasonably
believed to be in or  not opposed to UCU's best  interest, or, if the action  is
criminal in nature, upon a determination that the person seeking indemnification
had no reasonable cause to believe that his conduct was unlawful. This provision
also  requires UCU, upon  authorization by the  UCU Board, to  advance costs and
expenses, including  attorneys'  fees,  reasonably incurred  in  defending  such
actions; provided that any person seeking such an advance first provide UCU with
an  undertaking to repay any amount as to which it may be determined such person
is not entitled.
 
AMENDMENT OF CHARTERS
 
    The Maxim Charter may, in general, be amended only by an affirmative vote of
holders of a majority of the  outstanding shares of Maxim Common Stock  entitled
to  vote.  However,  the  provisions in  the  Maxim  Charter  concerning certain
business combinations (see "-- Business Combinations" below) may not be  changed
without  the affirmative vote of the holders  of at least 80% of the outstanding
shares of  Maxim Common  Stock  entitled to  vote.  Notwithstanding any  of  the
foregoing  to  the  contrary,  no  amendment  to  the  Maxim  Charter provisions
concerning indemnification may adversely affect  the right of a person  entitled
to  indemnification which arises  out of circumstances that  occur prior to such
amendment.
 
    The UCU Charter provides that provisions of the UCU Charter dealing with the
number, election,  and  removal  of  directors,  director  powers,  and  certain
business  combinations may  not be repealed  or amended  without the affirmative
vote of holders of at least 80%  of the outstanding shares of voting stock.  The
UCU  stockholders may otherwise amend, alter,  change or repeal any provision in
the UCU Charter as the DGCL provides.
 
AMENDMENT OF BYLAWS
 
    The Maxim Charter  and the  Maxim Bylaws provide  that the  Maxim Board  may
make,  alter, amend or repeal the Maxim Bylaws  by a majority vote of the entire
Maxim Board. This provision does not  limit shareholders' power to make,  alter,
amend or replace the Maxim Bylaws by a majority vote of shareholders present and
entitled  to vote  at an annual  or special  meeting, provided that  a quorum is
present. The UCU  Charter authorizes  the UCU Board  to make,  alter and  repeal
bylaws,  subject to the rights of stockholders at any regular or special meeting
to alter or repeal bylaws made by the  UCU Board, and to the rights, if any,  of
the  holders of any  class of stock. Notwithstanding  the previous sentence, the
affirmative vote of the holders of at least 80% of the outstanding shares of UCU
capital stock entitled to  vote generally in director  elections is required  to
amend  or repeal, or to  adopt any provision inconsistent  with, the sections of
the UCU Bylaws dealing  with the UCU  Board (Article Two)  and amending the  UCU
Bylaws  (Article Six, Section 6), unless  first approved by the affirmative vote
of at  least two-thirds  of the  Continuing  Directors, as  defined in  the  UCU
Charter.  The DGCL provides that a corporation's bylaws may otherwise be amended
by the affirmative vote of the holders  of a majority of the outstanding  shares
of the corporation entitled to vote thereon.

<PAGE>
NOTICE OF SHAREHOLDER PROPOSALS/NOMINATIONS OF DIRECTORS
 
    The  Maxim Bylaws have certain requirements  for providing advance notice of
the introduction  by  shareholders  of  business  to  be  transacted  at  annual
shareholders'  meetings. For any such proposal  properly to be brought before an
annual meeting, a shareholder of record, on the date both of giving such  notice
and  of determining  shareholders entitled to  vote at the  annual meeting, must
give timely notice of such  proposal in a proper  written form to the  company's
corporate  Secretary,  as  provided  in  the  Maxim  Bylaws.  To  be  timely,  a
shareholder's notice  to  the Secretary  must  be  delivered to  or  mailed  and
received  at the company's principal executive offices not less than 60 nor more
than 90 days prior to the date of the annual meeting of shareholders,  provided,
however,  that if less  than 70 days'  notice or prior  public disclosure of the
date of the meeting is  given to shareholders, notice  by the shareholder to  be
timely must be so received not later than the close of business on the tenth day
following  the day on  which such notice of  the date of  the annual meeting was
mailed or such public  disclosure of the  date of the  annual meeting was  made,
whichever occurs first.
 
    The  Maxim  Bylaws  require  that  a  shareholder's  notice  include  (i)  a
description of  the  proposed  business  and the  reasons  for  conducting  such
business,  (ii) the name and record address of such shareholder, (iii) the class
and number  of  shares  that  are  owned  beneficially  or  of  record  by  such
shareholder,  (iv) a description of any financial or other interest of each such
shareholder in  the proposal,  and (v)  a representation  that such  shareholder
intends  to appear  in person or  by proxy at  the annual meeting  to bring such
business before the meeting.
 
    The Maxim Bylaws permit shareholders to nominate persons for election to the
Maxim Board at  any annual  shareholders' meeting  if they  are shareholders  of
record  as of both  the date of giving  such notice and  the date of determining
shareholders entitled to  vote at the  annual meeting. A  shareholder must  give
timely  notice thereof in a  proper written form to  the corporate Secretary, as
provided in the bylaws. To be timely, a shareholder's notice must meet the  same
timeliness  requirements  as described  above  for providing  advance  notice of
business to be transacted at a shareholders' meeting.
 
    To be in proper written form,  a shareholder's notice to the Secretary  must
set  forth (a) as to  each person whom the  shareholder proposes to nominate for
election as a director (i) the name, age, business address and residence address
of the person, (ii) the principal occupation or employment of the person,  (iii)
the  class or series and  number of shares of capital  stock of the company that
are owned beneficially or of record by the person and (iv) any other information
relating to  the person  that  would be  required to  be  disclosed in  a  proxy
statement  or other filings required to be made in connection with solicitations
of proxies for election of directors pursuant to Section 14 of the Exchange Act,
and the  rules  and  regulations  promulgated thereunder;  and  (b)  as  to  the
shareholder  giving  the  notice  (i)  the  name  and  record  address  of  such
shareholder, (ii) the class or series and  number of shares of capital stock  of
the  company that are owned beneficially or of record by such shareholder, (iii)
a description of all arrangements or understandings between such shareholder and
each proposed nominee and  any other person or  persons (including their  names)
pursuant  to which the nomination(s) are to  be made by such shareholder, (iv) a
representation that such shareholder intends to appear in person or by proxy  at
the  meeting  to nominate  the persons  named in  the notice  and (v)  any other
information relating to such shareholder that would be required to be  disclosed
in  a proxy statement  or other filings  required to be  made in connection with
solicitations of proxies for election of directors pursuant to Section 14 of the
Exchange Act and the rules  and regulations promulgated thereunder. Such  notice
must be accompanied by a written consent of each proposed nominee to being named
as a nominee and to serve as a director if elected.
 
    The  UCU Bylaws provide that any stockholder who intends to bring any matter
other than the  election of directors  before a meeting  of stockholders and  is
entitled   to  vote  on  such  matter   must  deliver  written  notice  of  such
stockholder's intent to bring  such matter before  the meeting of  stockholders,
either  by personal delivery or by United  States mail, postage pre-paid, to the
Secretary of UCU. Such notice must be  received by the Secretary not later  than
the  following dates: (1) with respect to  an annual meeting of stockholders, 60
days   in    advance    of   such    meeting    if   such    meeting    is    to
 
                                       98
<PAGE>
be  held on  a day  which is  within 30  days preceding  the anniversary  of the
previous year's annual meeting  or 90 days  in advance of  such meeting if  such
meeting  is to be held on or after the anniversary of the previous year's annual
meeting; and (2) with respect to any other annual meeting of stockholders, or  a
special  meeting  of  stockholders,  the  close of  business  on  the  tenth day
following the date of public disclosure of the date of such meeting.
 
    Any UCU stockholder entitled  to vote for  the election of  a director at  a
meeting  called  for such  purpose may  nominate  one or  more persons  for such
election only  if  written  notice  of the  stockholder's  intent  to  make  the
nomination  is  given, either  by  personal delivery  or  by United  States mail
postage pre-paid, to the Secretary of UCU. The timing for receipt of the  notice
is  the same  as for receiving  notice of stockholders'  proposals. Such written
notice must set forth (i) the name, age, business address and residence  address
of  each  nominee proposed  in  such notice,  (ii)  the principal  occupation or
employment of each such nominee, (iii) the number of shares of capital stock  of
UCU  which are  beneficially owned  by each  such nominee,  and (iv)  such other
information concerning each such nominee as  would be required, under the  rules
of  the SEC, in  a proxy statement  soliciting proxies for  the election of such
nominee as a director. Such  notice will include a  signed consent of each  such
nominee to serve as a director of UCU, if elected.
 
STOCKHOLDER INSPECTION
 
    Under  the DGCL, any stockholder may inspect the corporation's stock ledger,
stockholder list and other books and  records for any proper purpose. A  "proper
purpose" is defined as a purpose reasonably related to such person's interest as
a  stockholder. The DGCL specifically provides that a stockholder may appoint an
agent for the  purpose of examining  the stock ledger,  list of stockholders  or
other  books and  records of  the corporation.  A stockholder  may apply  to the
Delaware Court of Chancery to compel  inspection in the event the  stockholder's
request to examine the books and records is refused. In general, the corporation
has the burden of proving an improper purpose where that stockholder requests to
examine  only the stockholder ledger  or the stockholder list,  and in all other
circumstances, the stockholder has the burden  of proving a proper purpose.  The
right of shareholders to inspect under the MGBCL is generally similar to that of
stockholders  under the DGCL. Neither the  MGBCL nor Missouri case law, however,
provides specific guidance as to whether a shareholder may appoint an agent  for
the  purpose of examining books and records or the extent to which a shareholder
must have a  "proper purpose." Accordingly,  in comparison with  the DGCL, in  a
given situation, a Missouri shareholder may be provided with less guidance as to
the  scope  of his  or  her ability  to  inspect the  books  and records  of the
corporation.
 
    The Maxim Bylaws provide that a shareholder has the right to inspect Maxim's
books only to the extent that the right is conferred by law, the Maxim  Charter,
the  Maxim Bylaws, or a resolution of  the Maxim Board. The list of shareholders
entitled to vote  at any  meeting will  be kept  on file  at Maxim's  registered
office  for ten days before the meeting and will be subject to Maxim shareholder
inspection at any time during that period, during usual business hours.
 
    The UCU Bylaws provide that  the UCU Board may  determine from time to  time
whether  and, if allowed,  when and under what  conditions and regulations UCU's
books and records will be open to stockholder inspection. Rights in this respect
will be limited  accordingly, except  as the  law requires  otherwise. Under  no
circumstances  will any  stockholder have  the right  to inspect  UCU's books or
records or receive any statement for an illegal or improper purpose. A  complete
list  of stockholders entitled to vote at each meeting of stockholders, prepared
in accordance with  the UCU  Bylaws, shall be  prepared by  UCU's Secretary  and
shall be open for examination by any stockholder, for any purpose germane to the
meeting,  during ordinary business hours for a period of at least 10 days before
every meeting, either  at a place  within the city  where the meeting  is to  be
held, or, if not so specified, at the place where the meeting will be held.
 
STOCKHOLDERS' VOTE FOR MERGERS
 
    In  the area of mergers or other corporate reorganizations, the DGCL differs
from the MGBCL  in a number  of respects. A  corporation incorporated under  the
DGCL must obtain the affirmative vote
 
                                       99
<PAGE>
(except  as indicated below and unless its certificate of incorporation provides
otherwise) of  the  holders of  a  majority of  the  outstanding shares  of  the
corporation   entitled  to  vote  thereon  to  approve  a  merger  with  another
corporation, the sale of  substantially all of the  corporation's assets or  the
voluntary  dissolution of  the corporation.  In the  same situations,  the MGBCL
requires the approval of persons holding at least two-thirds of the  outstanding
shares entitled to vote thereon.
 
    The DGCL does not require a stockholder vote of the surviving corporation in
a  merger if (i) the merger agreement does not amend the existing certificate of
incorporation, (ii) each outstanding share  of the surviving corporation  before
the  merger is  unchanged, and (iii)  the number of  shares to be  issued in the
merger does not exceed 20% of  the shares outstanding immediately prior to  such
issuance. The MGBCL has no such exception.
 
    Both  the  MGBCL and  the  DGCL do  not require  a  vote of  a corporation's
stockholders if such corporation  is merged with and  into a parent  corporation
that owns 90 percent or more of such corporation's stock.
 
APPRAISAL RIGHTS
 
    Both  the  DGCL  and  the MGBCL  provide  appraisal  rights  to shareholders
entitled to vote in merger transactions  (except as indicated below). The  MGBCL
also  provides such rights in  a sale of assets,  unless pursuant to a voluntary
dissolution of the  corporation, whereas the  DGCL does not.  The DGCL does  not
recognize  dissenters' rights of  appraisal in a merger  or consolidation if the
dissenting shares  of  the  corporation  are listed  on  a  national  securities
exchange,  designated as  a national  market system  security on  an interdealer
quotation system by the National Association of Securities Dealers, Inc. or held
of record  by  more  than 2,000  stockholders,  or  if the  corporation  is  the
surviving  corporation and no  vote of its stockholders  is required, subject to
certain exceptions.
 
ANTI-TAKEOVER STATUTES
 
    The MGBCL and DGCL contain certain provisions which may be deemed to have an
anti-takeover effect.
 
    The Missouri  business combination  statute protects  domestic  corporations
from  unsolicited  takeovers by  prohibiting  certain transactions.  The statute
restricts  certain  "Business  Combinations"   between  a  corporation  and   an
"Interested  Shareholder"  and  its "Affiliates"  and  "Associates"  (as defined
therein). A "Business Combination" includes  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" includes  any person  or entity which
beneficially owns or controls  20% or more of  the outstanding voting shares  of
the  corporation.  Pursuant  to  the Missouri  business  combination  statute, a
Missouri corporation may  at no time  engage in a  Business Combination with  an
Interested  Shareholder other  than (i) a  Business Combination  approved by the
board of  directors  prior to  the  date  on which  the  Interested  Shareholder
acquired  such status; (ii) a Business Combination  approved by the holders of a
majority  of  the  outstanding  voting  stock  not  beneficially  owned  by  the
Interested  Shareholder or its  Affiliates or Associates at  a meeting called no
earlier than  five years  after the  date on  which the  Interested  Shareholder
acquired  such status;  or (iii) a  Business Combination  that satisfies 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.
 
    The MGBCL exempts from its business combination provisions: (i) corporations
not having a class of voting stock  registered under Section 12 of the  Exchange
Act; (ii) corporations which adopt
 
                                      100
<PAGE>
provisions  in  their  original  articles  of  incorporation  or,  under certain
circumstances, adopt amendments  to their  bylaws expressly electing  not to  be
covered  by the statute; and (iii)  certain circumstances in which a shareholder
inadvertently becomes an Interested Shareholder. The Maxim Charter and the Maxim
Bylaws do not "opt out" of the Missouri business combination statute.
 
    The MGBCL also contains a "Control Share Acquisition Statute" which provides
that an "Acquiring Person"  who, after any acquisition  of shares of a  publicly
traded  corporation, has the voting power, when  added to all shares of the same
corporation previously owned or controlled by the Acquiring Person, to  exercise
or  direct the exercise of (i)  20% but less than 33  1/3%, (ii) 33 1/3% or more
but less than a majority or (iii) a majority of the voting power of  outstanding
stock  of such corporation, must obtain shareholder approval for the purchase of
the "Control Shares." If  approval is not given,  the Acquiring Person's  shares
lose  the right to vote.  The statute prohibits an  Acquiring Person from voting
its shares unless certain disclosure requirements  are met and the retention  or
restoration  of  voting  rights  is  approved by  both  (i)  a  majority  of the
outstanding voting stock, and  (ii) a majority of  the outstanding voting  stock
after  exclusion  of "Interested  Shares."  "Interested Shares"  are  defined as
shares owned by the Acquiring Person,  by directors who are also employees,  and
by  officers of the corporation. Shareholders  are given dissenters' rights with
respect to the vote on Control Share Acquisitions and may demand payment of  the
fair value of their shares.
 
    A  number of  acquisitions of  shares are  deemed not  to constitute Control
Share Acquisitions, including  good faith  gifts, transfers  pursuant to  wills,
purchases  pursuant to  an issuance  by the  corporation, mergers  involving the
corporation which satisfy the other requirements of the MGBCL, transactions with
a person who owned a majority of the voting power of the corporation within  the
prior  year,  or  purchases  from  a person  who  has  previously  satisfied the
provisions of the Control Share Acquisition  Statute so long as the  transaction
does  not result in the purchasing party  having voting power after the purchase
in a percentage range (such ranges are as set forth in the immediately preceding
paragraph) beyond the range for which the selling party previously satisfied the
provisions of the statute.  Additionally, a corporation  may exempt itself  from
application  of  the  statute  by  inserting  a  provision  in  its  articles of
incorporation or bylaws expressly electing not to be covered by the statute. The
Maxim Charter  and the  Maxim  Bylaws do  not "opt  out"  of the  Control  Share
Acquisition Statute.
 
    The  DGCL sections applicable to UCU  contain a business combination statute
similar to that contained in the  MGBCL. Like the Missouri business  combination
statute,  the  Delaware  business  combination  statute  generally  prohibits  a
domestic corporation from  engaging in  mergers or  other business  combinations
with  any person who is  the beneficial owner of 15%  or more of the outstanding
voting stock of the corporation  (an "Interested Stockholder"). The  prohibition
can  be  avoided if,  prior  to the  date on  which  the stockholder  becomes an
Interested Stockholder,  the  Board  of  Directors  of  a  Delaware  corporation
approves  either the business  combination or the  transaction which resulted in
the stockholder becoming an Interested  Stockholder. The MGBCL imposes a  longer
prohibition  period  on  transactions  with  Interested  Stockholders  than  the
three-year  prohibition  provided  for  under  the  DGCL,  thereby   potentially
increasing the period during which an unsolicited takeover may be frustrated. In
addition,  the  DGCL, unlike  its Missouri  counterpart, does  not apply  if the
Interested Stockholder obtains at  least 85% of  the corporation's voting  stock
upon  consummation  of  the  transaction  which  resulted  in  the stockholder's
becoming an Interested Stockholder. Thus, a person acquiring at least 85% of the
corporation's voting stock could circumvent the defensive provisions of the DGCL
while being unable to do so under the MGBCL.
 
    The DGCL does  not contain a  control share acquisition  statute similar  to
that contained in the MGBCL.
 
BUSINESS COMBINATIONS
 
    The  Maxim Charter provides that  the affirmative vote of  the holders of at
least 80% of  voting power  of Maxim  Common Stock  is required  to approve  any
Business  Combination with  an Interested Shareholder  unless certain exceptions
are   satisfied.   A    "Business   Combination"   is    defined   to    include
 
                                      101
<PAGE>
certain  transactions by  Maxim or any  of its  subsidiaries, including, without
limitation, (i) any merger or consolidation with an Interested Shareholder; (ii)
any sale, lease, exchange, transfer or other disposition (in one transaction  or
a  series) of a Substantial Part (as defined  therein) of the assets of Maxim to
an Interested Shareholder; (iii) the issuance of any securities to an Interested
Shareholder other than  on a pro  rata basis to  all holders of  the same  class
pursuant  to  a  stock  split  or  stock  dividend;  (iv)  any recapitalization,
reclassification,  or  similar   transaction  that   increases  the   Interested
Shareholder's proportionate voting power; (v) any liquidation, spinoff, split-up
or  dissolution of Maxim  that the Interested Shareholder  proposes; or (vi) any
agreement, contract or arrangement providing for an action specified in (i)-(v).
An "Interested Shareholder"  is defined  as any  person and  its affiliates  and
associates  that beneficially  owns 5% or  more of the  outstanding Maxim Common
Stock. The 80% voting requirement referred to above is not applicable if  either
(a)  a majority of  the Continuing Directors  (as defined in  the Maxim Charter)
approved the Business Combination, or (b) the cash or fair market value of other
consideration received per  share by the  holders of Maxim  Common Stock in  the
Business  Combination  equals  or  exceeds  the  highest  share  price  that the
Interested Shareholder  paid  for  Maxim  Common Stock  during  the  five  years
preceding the announcement of the Business Combination.
 
    The  UCU Charter  provides that  the affirmative vote  of the  holders of at
least 80% of UCU  stock entitled to  vote is required  to approve any  "Business
Transaction"  with a  "Related Person," or  any Business Transaction  in which a
Related Person has  an interest  (except proportionately as  a UCU  stockholder)
unless  certain exceptions are satisfied. A "Business Transaction" is defined to
include certain  transactions by  UCU  or any  of its  subsidiaries,  including,
without limitation, (i) any merger or consolidation of UCU or a subsidiary; (ii)
any  sale, lease, exchange, transfer or other disposition (in one transaction or
a series of transactions) of 20% or more  of the assets of UCU or a  subsidiary;
(iii)   any  sale,  lease,  exchange  transfer  or  other  disposition  (in  one
transaction or a series)  of 20% or more  of the assets of  a Related Person  to
UCU;  (iv) the  issuance, sale, exchange,  transfer or other  disposition of any
securities  of  UCU  or   a  subsidiary  by  UCU   or  a  subsidiary;  (v)   any
recapitalization,  reclassification  or  similar  transaction  that  increases a
Related Person's  proportionate  voting  power; (v)  any  liquidation,  spinoff,
split-up  or dissolution of UCU; and (vi) any agreement, contract or arrangement
providing for an action specified in  (i)-(v). A "Related Person" is defined  as
any person and any affiliate or associate which beneficially owns 20% or more of
UCU  outstanding Voting Stock.  The 80% voting requirement  referred to above is
not applicable if either (a) a majority of the Continuing Directors (as  defined
in  the  UCU Charter)  approved the  Business Transaction,  or (b)  the Business
Transaction was a merger or consolidation,  or sale of all or substantially  all
of UCU assets, and the cash or fair market value of other consideration received
per share by common stockholders (other than the Related Person) in the Business
Transaction   equals  at  least  the  greater  of  (1)  the  highest  amount  of
consideration that the Related Person  paid for a share  of UCU Common Stock  at
any time such person was a Related Person or in the transaction that resulted in
such  person's becoming  a Related Person,  provided, however,  that the highest
purchase price  will  be  appropriately adjusted  to  reflect  reclassification,
recapitalization,   stock  splits,   reverse  stock  splits   or  other  similar
adjustments in the  number of  shares, or the  declaration of  a stock  dividend
thereon,  between the last date  upon which the Related  Person paid the highest
price and the  effective date  of the  merger or  consolidation or  the date  of
distributing proceeds from the sale of all or substantially all of UCU assets to
stockholders,  or  (2) 110%  of the  book value  per share  of UCU  Common Stock
immediately before  the  first  public announcement  of  the  proposed  business
transaction  or on the date the Related  Party became a Related Party, whichever
is higher.
 
                            APPROVAL OF MAXIM PLANS
 
MAXIM STOCK INCENTIVE PLAN
 
    Pursuant to the  Merger Agreement, it  was agreed that  Maxim would adopt  a
stock  compensation plan to  replace the existing stock  incentive plans of KCPL
and UCU (except with respect to obligations
 
                                      102
<PAGE>
incurred or attributable to employment prior  to the Effective Time) subject  to
approval  by  stockholders.  Accordingly,  the  Maxim  Stock  Incentive  Plan is
submitted to the  shareholders of  KCPL for  approval, as  more fully  described
below.  The Maxim Stock Incentive Plan will become effective only if approved by
stockholders as described below, in which event it will become effective at  the
Effective Time and will terminate ten years thereafter.
 
    The  purpose of the  Maxim Stock Incentive  Plan is to  enable Maxim and its
Affiliates (as defined in the Maxim Stock Incentive Plan) to attract, retain and
motivate officers and employees and to provide Maxim and its Affiliates with the
ability to provide incentives linked to the profitability of Maxim's businesses,
increases in stockholder value  and the enhancement  of performance relating  to
customers.
 
    The  Maxim  Stock  Incentive  Plan  has been  designed  to  comply  with the
provisions of Section 162(m) of the Code which imposes limits on the ability  of
a public company to claim tax deductions for compensation paid to certain highly
compensated  executives. Section 162(m) of the Code generally denies a corporate
tax deduction for annual compensation in excess of $1,000,000 paid to the  chief
executive  officer  and the  four other  most highly  compensated officers  of a
public company.  Certain  types  of  compensation,  including  performance-based
compensation,  are generally excluded from this deduction limit. In an effort to
ensure that stock awards  under the Maxim Stock  Incentive Plan will qualify  as
performance-based  compensation, which is generally  deductible, the Maxim Stock
Incentive Plan is being  submitted to stockholders of  KCPL for approval at  the
KCPL  Meeting. KCPL  believes compensation payable  pursuant to  the Maxim Stock
Incentive Plan will  be deductible for  federal income tax  purposes under  most
circumstances.  However, under  certain circumstances such  as death, disability
and change  in control  (all as  defined  in the  Maxim Stock  Incentive  Plan),
compensation  not qualified under Section 162(m) of  the Code may be payable. By
approving the Maxim Stock  Incentive Plan, the  stockholders will be  approving,
among  other  things,  the performance  measures,  eligibility  requirements and
limits on various  stock awards  contained therein.  The affirmative  vote of  a
majority  of the votes entitled to be cast  by the holders of the shares of KCPL
Common Stock represented  at the KCPL  Meeting and entitled  to vote thereon  is
required  to  approve the  Maxim Stock  Incentive Plan  with respect  to Section
162(m) of  the  Code. Such  vote  will  also satisfy  the  stockholder  approval
requirements  of Section 422 of  the Code with respect to  the grant of ISOs and
Rule 16b-3 under  the Exchange  Act ("Rule 16b-3").  THE BOARD  OF DIRECTORS  OF
KCPL,  BY A UNANIMOUS  VOTE, RECOMMENDS A  VOTE FOR APPROVAL  OF THE MAXIM STOCK
INCENTIVE PLAN.
 
    Set forth below is a summary of certain material features of the Maxim Stock
Incentive Plan, which summary is qualified  in its entirety by reference to  the
actual plan attached as Annex F to this Joint Proxy Statement/Prospectus:
 
    ADMINISTRATION.   The Maxim Stock Incentive Plan will be administered by the
Maxim Compensation Committee or such other  committee of the Maxim Board as  the
Maxim  Board may from time  to time designate, which  will be composed solely of
not less than two directors who qualify as "disinterested persons" for  purposes
of  Rule 16b-3 and as "outside directors"  for purposes of Section 162(m) of the
Code. Among  other  things,  the  Maxim Compensation  Committee  will  have  the
authority,  subject to the  terms of the  Maxim Stock Incentive  Plan, to select
officers and employees to whom awards may  be granted, to determine the type  of
award  as well as  the number of shares  of Maxim Common Stock  to be covered by
each award, and to determine  the terms and conditions  of any such awards.  The
Maxim  Compensation Committee also  will have the authority  to adopt, alter and
repeal such administrative rules, guidelines  and practices governing the  Maxim
Stock  Incentive Plan  as it  shall deem advisable,  to interpret  the terms and
provisions of the Maxim  Stock Incentive Plan and  any awards issued  thereunder
and to otherwise supervise the administration of the Maxim Stock Incentive Plan.
All  decisions made  by the Maxim  Compensation Committee pursuant  to the Maxim
Stock Incentive Plan will be final and binding.
 
    ELIGIBILITY.  Officers and  salaried employees of  Maxim and its  Affiliates
designated  by  the  Maxim Compensation  Committee  who are  responsible  for or
contribute to the management, growth and
 
                                      103
<PAGE>
profitability of Maxim are eligible to  be granted awards under the Maxim  Stock
Incentive  Plan. No grant will be made under the Maxim Stock Incentive Plan to a
director who is not an officer or a salaried employee. The initial determination
of persons eligible to participate in the Maxim Stock Incentive Plan will not be
made until after the Effective Time by the Maxim Compensation Committee as  then
constituted. Accordingly, it is not possible to estimate at this time the number
of  persons who  will be  eligible to participate  in the  Maxim Stock Incentive
Plan.
 
    PLAN FEATURES.  The Maxim Stock Incentive Plan authorizes the issuance of up
to 9,000,000 shares of Maxim Common Stock  pursuant to the grant or exercise  of
stock  options (including ISOs),  SARs, restricted stock  and performance units,
but not more than 3,000,000 shares may be issued as restricted stock. No  single
participant  may be  granted awards pursuant  to the Maxim  Stock Incentive Plan
covering in excess of 600,000 shares of  Maxim Common Stock in any one  calendar
year  and no participant  may be granted  performance units in  any one calendar
year payable in cash in an amount  that would exceed $2,000,000. Subject to  the
foregoing  limits, the shares available under the Maxim Stock Incentive Plan can
be allocated among the various types of awards and among the participants as the
Maxim Compensation  Committee deems  appropriate. The  shares subject  to  grant
under  the Maxim Stock Incentive  Plan are to be  made available from authorized
but unissued shares or from treasury shares  as determined from time to time  by
the  Maxim Board. Awards may be granted for such terms as the Maxim Compensation
Committee may determine, except that the term of an ISO may not exceed ten years
from its date of  grant. No awards  outstanding on the  termination date of  the
Maxim  Stock Incentive Plan  shall be affected or  impaired by such termination.
Awards will not  be transferable, except  by will  and the laws  of descent  and
distribution  and, in  the case  of nonqualified  stock options  and any related
SARs, as a gift to an optionee's children. The Maxim Compensation Committee will
have broad authority to  fix the terms and  conditions of individual  agreements
with participants.
 
    As  indicated above, several types of stock-related grants can be made under
the Maxim Stock Incentive Plan. A summary of these grants is set forth below:
 
    STOCK OPTIONS.    The  Maxim  Stock  Incentive  Plan  authorizes  the  Maxim
Compensation  Committee to  grant options to  purchase Maxim Common  Stock at an
exercise price (the "option price") to be determined by the Committee. The Maxim
Stock  Incentive  Plan  permits  optionees,  with  the  approval  of  the  Maxim
Compensation  Committee, to  pay the  exercise price  of options  in cash, stock
(valued at its  fair market  value on  the date  of exercise)  or a  combination
thereof.  As noted above, options may be  granted either as ISOs or nonqualified
options. The principal difference between ISOs and nonqualified options is their
tax treatment. See "-- Certain Federal Income Tax Consequences."
 
    SARS.   The Maxim  Stock Incentive  Plan authorizes  the Maxim  Compensation
Committee  to grant  SARs in conjunction  with all  or part of  any stock option
granted under the  Maxim Stock  Incentive Plan. An  SAR entitles  the holder  to
receive  upon exercise the excess of the fair market value of a specified number
of shares of Maxim Common  Stock at the time of  exercise over the option  price
per share specified in the related stock option. Such amount will be paid to the
holder  in shares of Maxim Common Stock (valued  at its fair market value on the
date of  exercise),  cash or  combination  thereof, as  the  Maxim  Compensation
Committee   may  determine.  An  SAR  may  be  granted  in  conjunction  with  a
contemporaneously granted  ISO  or  a previously  or  contemporaneously  granted
nonqualified option. The option will be cancelled to the extent that the related
SAR  is exercised and the SAR will be cancelled to the extent the related option
is exercised.
 
    RESTRICTED STOCK.   The  Maxim  Stock Incentive  Plan authorizes  the  Maxim
Compensation  Committee  to  grant  restricted stock  to  individuals  with such
restriction periods as the Maxim Compensation Committee may designate. The Maxim
Compensation Committee  may,  prior  to granting  shares  of  restricted  stock,
designate certain participants as "Covered Employees" upon determining that such
participants  are or are expected to  be "covered employees" (within the meaning
of Section 162(m)(3) of the Code), with compensation in excess of the limitation
provided in Section 162(m) of the  Code, and will provide that restricted  stock
awards    to   these   Covered   Employees   cannot   vest   unless   applicable
 
                                      104
<PAGE>
performance goals established  by the  Maxim Compensation  Committee within  the
time  period  prescribed by  Section  162(m) of  the  Code are  satisfied. These
performance goals  must  be based  on  the  attainment of  specified  levels  of
earnings  per  share, market  share, stock  price,  sales, costs,  net operating
income, cash  flow,  retained earnings,  return  on equity,  return  on  assets,
economic  value  added,  results  of  customer  satisfaction  surveys, aggregate
product  price  and  other  product  price  measures,  safety  record,   service
reliability,   demand-side   management   (including   conservation   and   load
management),  operating  and  maintenance  cost  management,  energy  production
availability  and individual  performance measures. Such  performance goals also
may be based on the attainment of specified levels of Maxim's performance  under
one or more of the measures described above relative to the performance of other
corporations.  Performance goals based on  the foregoing factors are hereinafter
referred to  as "Performance  Goals."  With respect  to Covered  Employees,  all
Performance   Goals  must   be  objective   performance  goals   satisfying  the
requirements for "performance-based compensation" within the meaning of  Section
162(m)(4)  of the  Code. Notwithstanding  the foregoing,  the Maxim Compensation
Committee shall  have the  discretion to  grant to  an employee  who has  become
entitled  to an  award under the  Maxim MIC Plan  (see "-- Maxim  MIC Plan"), in
payment of all or any part of such award, shares of restricted stock that  shall
vest   without  regard  to  the  attainment  of  Performance  Goals.  The  Maxim
Compensation Committee also may condition the vesting of restricted stock awards
to participants who are not Covered Employees upon the satisfaction of these  or
other  applicable performance goals.  The provisions of  restricted stock awards
(including any applicable Performance Goals) need  not be the same with  respect
to  each  participant. During  the  restriction period,  the  Maxim Compensation
Committee may require that the  stock certificates evidencing restricted  shares
be  held  by Maxim.  Restricted stock  may not  be sold,  assigned, transferred,
pledged or otherwise encumbered. Other  than these restrictions on transfer  and
any  other  restrictions  the  Maxim  Compensation  Committee  may  impose,  the
participant will have all the rights of  a holder of stock holding the class  or
series of stock that is the subject of the restricted stock award.
 
    PERFORMANCE  UNITS.   The Maxim  Stock Incentive  Plan authorizes  the Maxim
Compensation Committee  to grant  performance units.  Performance units  may  be
denominated  in shares of Maxim Common Stock or cash, or may represent the right
to receive dividend equivalents with respect to shares of Maxim Common Stock, as
determined by  the  Maxim  Compensation Committee.  Performance  units  will  be
payable  in cash or shares of Maxim Common Stock if applicable Performance Goals
(based on one  or more of  the measures  described in the  section entitled  "--
Restricted  Stock" above)  determined by such  committee are  achieved during an
award cycle. An award cycle will consist of a period of consecutive fiscal years
or portions thereof designated  by the Maxim  Compensation Committee over  which
performance  units are  to be  earned. At the  conclusion of  a particular award
cycle, the Maxim Compensation Committee will determine the number of performance
units granted to  a participant  which have been  earned in  view of  applicable
Performance Goals and shall deliver to such participant (i) the number of shares
of  Maxim Common Stock equal to the value of performance units determined by the
Maxim Compensation Committee to have been  earned and/or (ii) cash equal to  the
value of such earned performance units. The Maxim Compensation Committee may, in
its discretion, permit participants to defer the receipt of performance units on
terms and conditions established by the Maxim Compensation Committee.
 
    The  Maxim Compensation Committee  will have the  authority to determine the
officers and employees to whom and the time or times at which performance  units
shall  be  awarded,  the  number  of performance  units  to  be  awarded  to any
participant, the duration of the award cycle and any other terms and  conditions
of  an  award. In  the event  that a  participant's employment  is involuntarily
terminated  or  in  the  event  of  the  participant's  retirement,  the   Maxim
Compensation  Committee  may waive  in whole  or  in part  any or  all remaining
payment limitations,  provided, however,  that  the satisfaction  of  applicable
Performance  Goals by a designated Covered Employee cannot be waived unless such
Covered Employee's employment is  terminated by death,  disability or change  of
control.
 
    AMENDMENT  AND  DISCONTINUANCE.    The Maxim  Stock  Incentive  Plan  may be
amended,  altered  or  discontinued  by  the  Maxim  Board,  but  no  amendment,
alteration or discontinuance may be made
 
                                      105
<PAGE>
which  would (i) impair the rights of an optionee under an option or a recipient
of an SAR, restricted stock award  or performance unit award previously  granted
without  the optionee's or recipient's consent, except such an amendment made to
qualify the Maxim Stock Incentive Plan for the exemption provided by Rule  16b-3
or (ii) disqualify the Maxim Stock Incentive Plan from the exemption provided by
Rule  16b-3. Except as expressly provided in the Maxim Stock Incentive Plan, the
Maxim Stock Incentive Plan  may not be amended  without stockholder approval  to
the extent such approval is required by law or agreement.
 
    CHANGES  IN CAPITALIZATION;  CHANGE IN CONTROL.   The  Maxim Stock Incentive
Plan provides that, in the event of any change in corporate capitalization, such
as a stock split, or a corporate transaction, such as any merger, consolidation,
share exchange, separation, spin-off or other distribution of stock or  property
of  Maxim or any reorganization or partial or complete liquidation of Maxim, the
Maxim Compensation Committee or the Maxim  Board may make such substitutions  or
adjustments  in the  aggregate number and  kind of shares  reserved for issuance
under the Maxim Stock Incentive  Plan, in the number,  kind and option price  of
shares subject to outstanding stock options and SARs, and in the number and kind
of  shares subject  to other  outstanding awards  granted under  the Maxim Stock
Incentive Plan as may be determined to be appropriate by the Maxim  Compensation
Committee  or the Maxim Board, in its sole discretion. The Maxim Stock Incentive
Plan also provides that in the event of  a change in control (as defined in  the
Maxim  Stock Incentive Plan) of Maxim (i) any SARs and stock options outstanding
as of the  date of  the change  of control which  are not  then exercisable  and
vested   will  become  fully  exercisable  and  vested,  (ii)  the  restrictions
applicable to restricted stock will lapse and such restricted stock shall become
free of all restrictions and fully  vested and (iii) all performance units  will
be  considered to be earned and payable  in full and any restrictions will lapse
and such performance units will be  settled in cash as promptly as  practicable.
The  holders of options (other than options  of holders subject to Section 16(b)
of the Exchange Act that were granted not more than six months before the change
in control) will have  the right, for a  period of 60 days  after such date,  to
surrender  such options in  exchange for a  cash payment based  on the change in
control price  (as defined  in  the Maxim  Stock  Incentive Plan).  However,  if
settlement  in  cash would  disqualify  a transaction  from pooling-of-interests
accounting treatment, the Maxim Compensation Committee may substitute stock.
 
    FEDERAL INCOME TAX CONSEQUENCES.  The following discussion is intended  only
as  a brief summary of  the federal income tax  rules relevant to stock options,
SARs, restricted stock and performance units. The laws governing the tax aspects
of awards are highly technical and such laws are subject to change.
 
  - NONQUALIFIED OPTIONS AND  SARS.   Upon the  grant of  a nonqualified  option
    (with or without an SAR), the optionee will not recognize any taxable income
    and  Maxim will not be entitled to a deduction. Upon the exercise of such an
    option or an SAR, the excess of the fair market value of the shares acquired
    on the exercise of the option over  the option price (the "spread"), or  the
    consideration paid to the optionee upon exercise of the SAR, will constitute
    compensation  taxable to the optionee as ordinary income. In determining the
    amount of the spread  or the amount of  consideration paid to the  optionee,
    the  fair market value of the stock on  the date of exercise is used, except
    that in the case of an optionee subject to the six month short-swing  profit
    recovery provisions of Section 16(b) of the Exchange Act (generally officers
    and directors of Maxim), the fair market value will be determined six months
    after  the date on which the option was  granted (if such date is later than
    the exercise date) unless such optionee elects to be taxed based on the fair
    market value at the  date of exercise. Any  such election (a "Section  83(b)
    election") must be made and filed with the IRS within 30 days after exercise
    in  accordance with the regulations under  Section 83(b) of the Code. Maxim,
    in computing  its  federal income  tax,  will  generally be  entitled  to  a
    deduction in an amount equal to the compensation taxable to the optionee.
 
  - ISOS.    An optionee  will  not recognize  taxable  income on  the  grant or
    exercise of an ISO. However, the spread at exercise will constitute an  item
    includable in alternative minimum taxable
 
                                      106
<PAGE>
    income, and thereby may subject the optionee to the alternative minimum tax.
    Such  alternative  minimum  tax  may be  payable  even  though  the optionee
    receives no cash upon the exercise of his ISO with which to pay such tax.
 
          Upon the  disposition  of shares  of stock  acquired pursuant  to  the
    exercise of an ISO after (i) two years from the date of grant of the ISO and
    (ii)  one year after  the transfer of  the shares to  the optionee (the "ISO
    Holding Period"),  the optionee  will recognize  long-term capital  gain  or
    loss,  as the case  may be, measured  by the difference  between the stock's
    selling price  and the  exercise price.  Maxim is  not entitled  to any  tax
    deduction  by reason of the grant  or exercise of an ISO,  or by reason of a
    disposition of stock  received upon exercise  of an ISO  if the ISO  Holding
    Period  is satisfied. Different rules apply  if the optionee disposes of the
    shares of stock acquired
    pursuant to the exercise of an ISO before the expiration of the ISO  Holding
    Period.
 
  - RESTRICTED  STOCK.  A participant who is granted restricted stock may make a
    Section 83(b) election to have the grant taxed as compensation income at the
    date  of  receipt,  with  the  result  that  any  future  appreciation   (or
    depreciation)  in the value of the shares of stock granted shall be taxed as
    capital gain (or loss) upon a subsequent sale of the shares. However, if the
    participant does not make a Section  83(b) election, then the grant will  be
    taxed  as compensation income at the full fair market value on the date that
    the restrictions imposed on the shares expire. Unless a participant makes  a
    Section  83(b)  election,  any  dividends  paid  on  stock  subject  to  the
    restrictions are  compensation income  to the  participant and  compensation
    expense to Maxim. Maxim is generally entitled to an income tax deduction for
    any  compensation income taxed to the participant, subject to the provisions
    of Section 162(m) of the Code.
 
  - PERFORMANCE UNITS.  A  participant who has been  granted a performance  unit
    award  will  not realize  taxable income  until  the applicable  award cycle
    expires and  the participant  is  in receipt  of  the stock  distributed  in
    payment  of the award  or an equivalent  amount of cash,  at which time such
    participant will realize ordinary income equal to the full fair market value
    of the shares  delivered or the  amount of  cash paid. At  that time,  Maxim
    generally  will  be  allowed  a corresponding  tax  deduction  equal  to the
    compensation taxable to the  award recipient, subject  to the provisions  of
    Section 162(m) of the Code.
 
    NEW  PLAN BENEFITS.  It  cannot be determined at  this time what benefits or
amounts, if any,  will be received  by or allocated  to any person  or group  of
persons  under the Maxim  Stock Incentive Plan  if such plan  is adopted or what
benefits or amounts would have  been received by or  allocated to any person  or
group  of persons for the last fiscal year if the plan had been in effect. These
determinations will be made by the Maxim Compensation Committee.
 
MAXIM MIC PLAN
 
    Pursuant to the  Merger Agreement,  it was  agreed that  Maxim would  adopt,
subject  to  shareholder  approval,  an annual  incentive  plan  to  replace the
existing short-term incentive compensation  plans of KCPL  and UCU (except  with
respect  to  obligations incurred  or attributable  to  employment prior  to the
Effective Time), effective as of the Effective Time. The Maxim MIC Plan will not
become effective with respect to individuals  who are subject to Section  162(m)
of the Code unless the shareholder approval described below is obtained.
 
    The  purpose of the Maxim MIC Plan  is to provide a significant and flexible
economic opportunity to selected  officers and salaried  employees of Maxim  and
its  Affiliates (as defined in the Maxim MIC  Plan) in an effort to reward their
individual and  group  contributions to  Maxim  and  to more  closely  link  the
financial interests of management, shareholders and customers.
 
                                      107
<PAGE>
    The  Maxim MIC Plan is  designed to take into  account Section 162(m) of the
Code, which generally denies a  corporate tax deduction for annual  compensation
exceeding $1,000,000 paid to the chief executive officer and the four other most
highly  compensated officers of a public company. Certain types of compensation,
including performance-based  compensation,  are  excluded  from  this  deduction
limit. In an effort to ensure that compensation payable under the Maxim MIC Plan
to  certain executives  will qualify  as performance-based  compensation that is
generally tax-deductible, the Maxim MIC Plan is being submitted to  shareholders
of  KCPL  for approval  at  the KCPL  Meeting.  KCPL believes  that compensation
payable pursuant to the Maxim MIC Plan will be deductible for federal income tax
purposes under most circumstances. However, under certain circumstances such  as
death,  disability and change in control (all as defined in the Maxim MIC Plan),
compensation not qualified under Section 162(m)  of the Code may be payable.  By
approving the Maxim MIC Plan, KCPL's shareholders will be approving, among other
things,  the performance measures, eligibility requirements and annual incentive
award limits contained therein. The affirmative vote of a majority of the  votes
entitled  to  be  cast  by  the  holders of  the  shares  of  KCPL  Common Stock
represented at the  KCPL Meeting  and entitled to  vote thereon  is required  to
approve the Maxim MIC Plan. THE BOARD OF DIRECTORS OF KCPL, BY A UNANIMOUS VOTE,
RECOMMENDS A VOTE FOR APPROVAL OF THE MAXIM MIC PLAN.
 
    Set  forth below is a summary of  certain material features of the Maxim MIC
Plan, which summary is qualified in its entirety by reference to the actual plan
attached as Annex G to this Joint Proxy Statement/Prospectus:
 
    ADMINISTRATION.   The Maxim  MIC  Plan will  be  administered by  the  Maxim
Compensation  Committee, or such other committee of the Maxim Board as the Maxim
Board may from time to time designate, which, unless the Maxim Board  determines
otherwise,  will be composed solely of not less than two "disinterested persons"
who qualify as "outside directors" for  purposes of Section 162(m) of the  Code.
The  Maxim Compensation  Committee will  have sole  authority to  make rules and
regulations relating  to the  administration  of the  Maxim  MIC Plan,  and  any
interpretations  and decisions of the  Maxim Compensation Committee with respect
to the Maxim MIC Plan will be final and binding.
 
    ELIGIBILITY.  The Maxim Compensation Committee will, in its sole discretion,
determine those officers and salaried employees  of Maxim who shall be  eligible
to participate in the Maxim MIC Plan for a given period (an "Incentive Period").
These  participants  will be  selected based  upon their  opportunity to  have a
substantial impact on Maxim's results. Participation in the Maxim MIC Plan by  a
participant   during  a  given  Incentive  Period  does  not  require  continued
participation by  such  participant  in any  subsequent  Incentive  Period.  The
initial  determination of persons eligible to  participate in the Maxim MIC Plan
will not  be made  until after  the  Effective Time  by the  Maxim  Compensation
Committee  as then constituted.  Accordingly, it is not  possible to estimate at
this time the number of persons who will be eligible to participate in the Maxim
MIC Plan.
 
    PLAN FEATURES.   The Maxim MIC  Plan provides for  the payment of  incentive
awards  to participants  designated by  the Maxim  Compensation Committee, which
payments may be conditioned upon  the attainment of pre-established  performance
goals or upon such other factors or criteria as the Maxim Compensation Committee
shall  determine. Such performance goals may  be different for each participant.
Bonus amounts are  determined by multiplying  a participant's "Target  Incentive
Award"  by  a percentage  which  varies depending  on  the extent  to  which the
performance goals or other  factors or criteria  are satisfied. A  participant's
Target Incentive Award, in turn, is determined by multiplying such participant's
base  salary  as  of  the last  day  of  the applicable  Incentive  Period  by a
percentage  designated  by  the  Maxim  Compensation  Committee,  in  its   sole
discretion,  which percentage  need not  be the  same for  each participant (and
which may  exceed 100%).  The  Maxim Compensation  Committee  may, in  its  sole
discretion, increase or decrease the amount of any incentive awards payable to a
participant  and  may, in  recognition of  special circumstances,  pay incentive
awards even if not earned, provided that the Maxim Compensation Committee cannot
increase the  amount  of any  incentive  awards payable  to  certain  designated
"Covered Employees." Incentive awards payable under the
 
                                      108
<PAGE>
Maxim  MIC Plan to certain designated "Covered Employees" are subject to special
restrictions described in the following section. Incentive awards are payable in
cash, shares  of  Maxim  Common  Stock  or in  such  other  form  as  the  Maxim
Compensation Committee may determine.
 
    DESIGNATED  COVERED EMPLOYEES.   The Maxim Compensation  Committee will have
the authority,  in its  sole discretion,  to designate  certain participants  as
"Covered  Employees" for a specified Incentive Period upon determining that such
participants are or are expected to  be "covered employees" (within the  meaning
of  Section 162(m) of the  Code) for such Incentive  Period with compensation in
excess of the limitation provided in Section  162(m) of the Code. Not more  than
90  days after the beginning of the  Incentive Period, and, in any event, before
25% or  more  of  the  Incentive Period  has  elapsed,  the  Maxim  Compensation
Committee will establish the performance goals for the bonus award opportunities
of these Covered Employees. Such performance goals are to be comprised of one or
more  of the following measures: earnings  per share, market share, stock price,
sales, costs,  net operating  income, cash  flow, retained  earnings, return  on
equity,   economic  value  added,  results  of  customer  satisfaction  surveys,
aggregate product price and other product price measures, safety record, service
reliability,   demand-side   management   (including   conservation   and   load
management),  operating  and  maintenance  cost  management,  energy  production
availability and individual  performance measures. Such  performance goals  also
may be based on the attainment of specified levels of performance by Maxim under
one or more of the measures described above relative to the performance of other
corporations.  With respect to Covered Employees,  all Performance Goals must be
objective performance goals satisfying  the requirements for  "performance-based
compensation" within the meaning of Section 162(m) of the Code. Incentive awards
payable  to Covered Employees are to be  calculated in the same manner described
in the  "-- Plan  Features"  section above,  except that  subjective  individual
performance  ratings cannot be  used to increase the  amount of incentive awards
payable to  Covered Employees.  No  incentive awards  will  be paid  to  Covered
Employees  if the minimum  applicable pre-established Performance  Goals are not
satisfied, unless the  Covered Employee's  employment is  terminated because  of
death,  disability or a  change of control.  Furthermore, the Maxim Compensation
Committee will have the authority to  decrease, but not to increase, the  amount
of   incentive  awards  otherwise  payable  to  Covered  Employees  pursuant  to
pre-established performance  goals  and  payment formulas.  The  maximum  amount
payable to any Covered Employee for any fiscal year of Maxim will be $3,000,000.
 
    AMENDMENT AND DISCONTINUANCE.  The Maxim Board may amend, alter, discontinue
or otherwise modify the Maxim MIC Plan from time to time, but no amendment will,
without  the consent of the participant affected, impair any award made prior to
the effective date of the modification.
 
    NEW PLAN BENEFITS.  It  cannot be determined at  this time what benefits  or
amounts,  if any,  will be received  by or allocated  to any person  or group of
persons under  the Maxim  MIC Plan  if the  Maxim MIC  Plan is  adopted or  what
benefits  or amounts would have  been received by or  allocated to any person or
group of persons  for the last  fiscal year if  the Maxim MIC  Plan had been  in
effect.

               UNAUDITED PRO FORMA COMBINED FINANCIAL INFORMATION
 
    The  following  unaudited  pro  forma  financial  information  combines  the
historical consolidated balance sheets and statements of income of KCPL and UCU,
including their respective subsidiaries, after giving effect to the Mergers. The
unaudited pro forma combined  balance sheet at March  31, 1996, gives effect  to
the  Mergers as if they had occurred at  March 31, 1996. The unaudited pro forma
combined statements of income for  each of the three  years in the period  ended
December  31, 1995 and the  three-month periods ended March  31, 1996, and 1995,
give effect to the  Mergers as if  they had occurred at  January 1, 1993.  These
statements  are prepared on the basis of accounting for the Mergers as a pooling
of interests and are based on the assumptions set forth in the notes thereto.
 
    The following pro forma  financial information has  been prepared from,  and
should  be  read  in  conjunction with,  the  historical  consolidated financial
statements and related  notes thereto of  KCPL and UCU,  incorporated herein  by
reference.  The  following  information  is not  necessarily  indicative  of the
financial position or operating results that would have occurred had the Mergers
been consummated on the date, or at the beginning of the periods, for which  the
Mergers  are  being given  effect  nor is  it  necessarily indicative  of future
operating results or financial position. See "INCORPORATION OF CERTAIN DOCUMENTS
BY REFERENCE" in this Joint Proxy Statement/Prospectus.

           NOTES TO UNAUDITED PRO FORMA COMBINED FINANCIAL STATEMENTS
 
1.   The pro forma combined financial  statements reflect the conversion of each
    outstanding share of UCU Common Stock into one share of Maxim Common  Stock,
    as  provided  in  the Merger  Agreement.  The pro  forma  combined financial
    statements are  presented  as if  the  companies were  combined  during  all
    periods included therein.
 
2.  The allocation between KCPL and UCU and their customers of the approximately
    $600 million in net estimated cost savings over the 10-year period following
    the  Mergers, less transaction  costs, will be  subject to regulatory review
    and approval. Transaction costs, currently estimated to be approximately $40
    million (including  fees  for financial  advisors,  attorneys,  accountants,
    consultants,  filings  and printing),  are  being deferred  for post-Mergers
    amortization in accordance with future regulatory approval. As of March  31,
    1996,  $5.4  million  and  $4.2 million  in  merger-related  costs  had been
    deferred by KCPL and UCU, respectively.
 
    The net estimated cost savings and transactions costs do not reflect certain
    other costs that could be incurred by Maxim, such as increases or  decreases
    in  costs caused by the provisions of the Employment Agreements with Messrs.
    Jennings and Green,  Severance Agreements  with certain  executives and  the
    Maxim  Plans. See "THE MERGERS -- Employment Agreements," "-- Employee Plans
    and Severance Arrangements," "-- Maxim Plans" and "APPROVAL OF MAXIM  PLANS"
    in this Joint Proxy Statement/Prospectus.
 
    The  net estimated costs savings, transaction  costs and certain other costs
    have not  been reflected  in  the pro  forma combined  financial  statements
    because  of the  inability to predict  regulatory treatment  or estimate the
    amount of such costs that would impact any one period.
 
3.    Intercompany  transactions   (including  purchased  and  exchanged   power
    transactions)  between KCPL  and UCU during  the periods  presented were not
    material and, accordingly, no pro  forma adjustments were made to  eliminate
    such  transactions.  All  financial  statement  presentation  and accounting
    policy differences are  immaterial and  have not  been adjusted  in the  pro
    forma combined financial statements.
 
4.   Prior to  the consummation of the  Mergers, KCPL and  UCU must redeem their
    preferred stock outstanding as provided in the Merger Agreement. Because the
    basis of accounting for the Mergers is a pooling of interests, the effect of
    these redemptions is not required to be reflected in the pro forma  combined
    financial  statements. The only redemption premium, as of December 31, 1995,
    is $755,000 applicable to KCPL Preferred Stock. The on-going effect of these
    redemptions is anticipated to be immaterial.
 
5.  The fully  diluted earnings per common  share was determined assuming  UCU's
    outstanding  Convertible  Subordinated  Debentures and  UCU's  $1.775 Series
    Cumulative Convertible Preference Stock were converted into UCU Common Stock
    at the  beginning of  the periods  presented. In  calculating fully  diluted
    earnings  per share, earnings  available for common  shares were adjusted to
    eliminate interest expense, net  of tax, and to  eliminate dividends on  the
    Convertible Preference Stock.
 
6.  In other parts of this Joint Proxy Statement/Prospectus, EBITDA, which means
    earnings before interest, taxes, depreciation and amortization, is used as a
    financial  measurement. EBITDA is not intended to replace net income or cash
    flows  from  operations   computed  under   generally  accepted   accounting
    principles.  The Unaudited  Pro Forma Combined  Financial Statements contain
    financial information prepared on a basis consistent with generally accepted
    accounting principles.

    to exist, and each holder of  a Certificate (as defined in SECTION  2.2(B)),
    formerly  representing any such  shares shall cease to  have any rights with
    respect to such shares,  except the right to  receive shares of KCPL  Common
    Stock  to be  issued in  consideration therefor  upon the  surrender of such
    Certificate in accordance with Section 2.2.

    Stock that are owned by  UCU as treasury stock or  by KCPL or by any  wholly
    owned  Subsidiary of UCU  or KCPL shall  be cancelled and  retired and shall
    cease to exist and no stock of  KCPL or other consideration shall be  issued
    or delivered in exchange therefor.
 
       (iii)  REDEMPTION OF  KCPL PREFERRED STOCK.   Prior to  the UCU Effective
    Time, the  Board  of  Directors  of  KCPL  shall  call  for  redemption  all
    outstanding shares of KCPL Preferred Stock (as defined in SECTION 4.3), at a
    redemption  price equal to the amount set  forth in the Restated Articles of
    Consolidation of KCPL, together with all dividends accrued and unpaid to the
    date of  such  redemption. All  shares  of  KCPL Preferred  Stock  shall  be
    redeemed so that no such shares shall be deemed to be outstanding at the UCU
    Effective Time or entitled to vote on the approval of this Agreement and the
    transactions contemplated hereby.
 
       (iv)  REDEMPTION OF UCU PREFERRED  STOCK.  The Board  of Directors of UCU
    shall take  all action  necessary to  cause all  outstanding shares  of  UCU
    Preferred  Stock (as defined in SECTION 5.3) to be redeemed on March 3, 1997

    price  equal to the amount set forth  in the Certificate of Incorporation of
    UCU, together with  all dividends  accrued and unpaid  to the  date of  such
    redemption.  All shares of UCU Preferred Stock  shall be redeemed so that no
    such shares shall be deemed to be  outstanding at the UCU Effective Time  or
    entitled  to vote  on the  approval of  this Agreement  and the transactions
    contemplated hereby. The redemption price shall be paid in cash by UCU  from
    its  own cash resources or  its own line of credit.  UCU and KCPL agree that
    under no  circumstances  shall  the  payment  of  the  redemption  price  be
    financed,  guaranteed, secured, loaned,  reimbursed or otherwise facilitated
    or provided directly or indirectly by KCPL or any of the KCPL Subsidiaries.
 
    (b) As of the Consolidating Effective  Time, by virtue of the  Consolidating
Merger  and without any action on the part of any holder of any capital stock of
KCPL or the  UCU Surviving  Corporation, each  issued and  outstanding share  of
capital  stock of the  UCU Surviving Corporation shall  no longer be outstanding

    Section 2.2  ISSUANCE OF NEW CERTIFICATES.
 
    (a)  DEPOSIT  WITH EXCHANGE AGENT.   As  soon as practicable  after the  UCU
Effective  Time, KCPL  shall deposit,  in trust  for the  benefit of  holders of
Certificates, with such bank or trust company mutually agreeable to UCU and KCPL
(the "EXCHANGE AGENT"),  certificates representing shares  of KCPL Common  Stock
required  to effect the issuance referred to in Section 2.1(a)(i), together with
cash payable in respect of fractional shares pursuant to Section 2.2(d).
 
    (b)  ISSUANCE PROCEDURES.   As soon as  practicable after the UCU  Effective
Time, the Exchange Agent shall mail to each holder of record of a certificate or
certificates  (the "CERTIFICATES") which immediately  prior to the UCU Effective
Time represented outstanding shares of UCU Common Stock (the "CANCELLED SHARES")
that were  cancelled and  became instead  the right  to receive  shares of  KCPL
Common  Stock (the "KCPL SHARES") pursuant to Section 2.1(a)(i): (i) a letter of
transmittal (which shall specify  that delivery shall be  effected, and risk  of
loss  and title to the Certificates shall pass, only upon actual delivery of the
Certificates to the Exchange Agent) and  (ii) instructions for use in  effecting
the surrender of the Certificates in exchange for certificates representing KCPL
Shares.  Upon surrender of a Certificate  to the Exchange Agent for cancellation
(or to such other agent or agents as  may be appointed by agreement of KCPL  and
UCU),  together  with  a duly  executed  letter  of transmittal  and  such other
documents as the Exchange  Agent shall require, the  holder of such  Certificate
shall  be entitled  to receive a  certificate or  certificates representing that
number of whole KCPL Shares which such holder has the right to receive  pursuant
to the provisions of this Article II. In the event of a transfer of ownership of
Cancelled  Shares which  is not  registered in  the transfer  records of  UCU, a
certificate representing the  proper number of  KCPL Shares may  be issued to  a
transferee if the Certificate representing such Cancelled Shares is presented to
the Exchange Agent, accompanied by all documents required to evidence and effect
such transfer and by evidence satisfactory to the
 
                                      A-9
<PAGE>
Exchange  Agent that any  applicable stock transfer taxes  have been paid. Until
surrendered as  contemplated by  this  Section 2.2,  each Certificate  shall  be
deemed  at any time after the UCU Effective  Time to represent only the right to
receive upon such surrender the certificate representing KCPL Shares and cash in
lieu of  any fractional  shares of  KCPL Common  Stock as  contemplated by  this
Section 2.2.
 
    (c)   DISTRIBUTIONS WITH  RESPECT TO UNSURRENDERED SHARES.   No dividends or
other distributions declared or made after  the UCU Effective Time with  respect
to  KCPL Shares with a record date after the UCU Effective Time shall be paid to
the holder of  any unsurrendered  Certificate with  respect to  the KCPL  Shares
represented  thereby and no cash  payment in lieu of  fractional shares shall be
paid to any such holder pursuant to Section 2.2(d) until the holder of record of
such Certificate  shall surrender  such Certificate.  Subject to  the effect  of
unclaimed  property, escheat and  other applicable laws,  following surrender of
any such  Certificate,  there  shall  be  paid  to  the  record  holder  of  the
certificates  representing whole  KCPL Shares issued  in consideration therefor,
without interest, (i)  at the time  of such  surrender, the amount  of any  cash
payable  in lieu of a fractional share of KCPL Common Stock to which such holder
is entitled pursuant  to Section  2.2(d) and the  amount of  dividends or  other
distributions  with a record date after  the UCU Effective Time theretofore paid
with respect to such whole KCPL Shares and (ii) at the appropriate payment date,
the amount of dividends or other distributions with a record date after the  UCU
Effective Time but prior to surrender and a payment date subsequent to surrender
payable with respect to such whole KCPL Shares.
 
    (d)    NO  FRACTIONAL SECURITIES.    No certificates  or  scrip representing
fractional shares of KCPL  Common Stock shall be  issued upon the surrender  for
exchange  of Certificates and such fractional shares shall not entitle the owner
thereof to vote  or to  any other rights  of a  holder of KCPL  Common Stock.  A
holder  of  UCU  Common  Stock  who would  otherwise  have  been  entitled  to a
fractional share  of KCPL  Common Stock  shall  be entitled  to receive  a  cash
payment  in lieu of such  fractional share in an amount  equal to the product of
such fraction  multiplied by  the  average of  the  last reported  sales  price,
regular  way, per  share of  KCPL Common  Stock on  the New  York Stock Exchange
("NYSE") Composite Tape for  the five business days  prior to and including  the
last business day on which KCPL Common Stock was traded on the NYSE, without any
interest thereon.
 
    (e)  BOOK ENTRY.  Notwithstanding any other provision of this Agreement, the
letter  of transmittal referred to in Section 2.2(b) may, at the option of KCPL,
provide for the ability of  a holder of one or  more Certificates to elect  that
KCPL  Shares  to  be received  in  exchange  for the  Cancelled  Shares formerly
represented by such surrendered Certificates be issued in uncertificated form or
to elect that such  KCPL Shares be  credited to an  account established for  the
holder under the dividend reinvestment and stock purchase plan of KCPL.
 
    (f)   CLOSING OF TRANSFER BOOKS.  From and after the UCU Effective Time, the
stock transfer books of UCU shall be closed and no registration of any  transfer
of  any capital stock of UCU shall thereafter be made on the records of UCU. If,
after the UCU Effective Time, Certificates are presented to KCPL, they shall  be
cancelled  and exchanged for certificates representing the appropriate number of
KCPL Shares, as provided in this Section 2.2.
 
    (g)   TERMINATION OF  EXCHANGE AGENT.   Any  certificates representing  KCPL
Shares  deposited with  the Exchange  Agent pursuant  to Section  2.2(a) and not
exchanged within one year after the UCU Effective Time pursuant to this  Section
2.2  shall be returned by the Exchange Agent to KCPL, which shall thereafter act
as Exchange Agent.  All funds  held by  the Exchange  Agent for  payment to  the
holders  of unsurrendered Certificates and unclaimed at the end of one year from
the UCU Effective Time shall be returned to KCPL; after which time any holder of
unsurrendered Certificates shall  look as a  general creditor only  to KCPL  for
payment  of such funds  to which such  holder may be  due, subject to applicable
law. KCPL shall not be liable to  any person for such shares or funds  delivered
to  a public official pursuant to  any applicable abandoned property, escheat or
similar law. As used in this Agreement, the term "PERSON" shall mean any natural
person, corporation, general or limited partnership, limited liability  company,
joint venture, trust, association or entity of any kind.

Disclosure  Schedule shall  be deemed  to be made  as of  the Original Execution
Date. KCPL shall have no obligation  to update the KCPL Disclosure Schedule  for

standing to do business in each jurisdiction in which the nature of its business
or  the  ownership  or  leasing  of   its  assets  and  properties  makes   such

fairly present the financial position  of KCPL as of  the dates thereof and  the
results of its operations and cash flows for the periods then ended, subject, in
the  case of  the unaudited interim  financial statements,  to normal, recurring
audit adjustments. True, accurate and  complete copies of the Restated  Articles
of  Consolidation and by-laws  of KCPL, as  in effect on  the Original Execution
Date, are included (or incorporated by reference) in the KCPL SEC Reports.

and  each of  the KCPL  Subsidiaries have conducted  their business  only in the
ordinary course of  business consistent  with past  practice and  there has  not
been, and no fact or condition exists which would have or, insofar as reasonably
can  be foreseen, could have, a material adverse effect on the business, assets,
financial condition, results  of operations or  prospects of KCPL  and the  KCPL
Subsidiaries taken as a whole (a "KCPL MATERIAL ADVERSE EFFECT").

Material Adverse Effect.

    Section  4.10  EMPLOYEE MATTERS; ERISA.  Except as set forth in Section 4.10

        (a)  BENEFIT  PLANS.  Section  4.10(a) of the  KCPL Disclosure  Schedule
    contains  a true and complete list of each written or oral material employee
    benefit plan, policy  or agreement covering  employees, former employees  or
    directors   of   KCPL  and   each  of   the   KCPL  Subsidiaries   or  their
 
                                      A-16
<PAGE>
    beneficiaries, or providing benefits to such persons in respect of  services
    provided  to any  such entity, including,  but not limited  to, any employee
    benefit plans within the meaning of Section 3(3) of the Employee  Retirement
    Income  Security  Act of  1974, as  amended ("ERISA")  and any  severance or
    change in control agreement (collectively, the "KCPL BENEFIT PLANS").
 
        (b)   CONTRIBUTIONS.   All  material  contributions and  other  payments
    required  to be  made by KCPL  or any of  the KCPL Subsidiaries  to any KCPL
    Benefit Plan (or to any person pursuant to the terms thereof) have been made
    or the amount of such payment or contribution obligation has been  reflected
    in the KCPL Financial Statements.
 
        (c)  QUALIFICATION; COMPLIANCE.  Each of the KCPL Benefit Plans intended
    to  be "qualified" within the meaning of Section 401(a) of the Code has been
    determined by the Internal Revenue Service  (the "IRS") to be so  qualified,
    and,  to  the  best  knowledge  of KCPL,  no  circumstances  exist  that are
    reasonably expected  by  KCPL  to  result in  the  revocation  of  any  such
    determination. KCPL is in compliance in all material respects with, and each
    of  the KCPL Benefit Plans is and has been operated in all material respects
    in compliance with,  all applicable  laws, rules  and regulations  governing
    such  plan, including,  without limitation,  ERISA and  the Code.  Each KCPL
    Benefit Plan intended to provide for  the deferral of income, the  reduction
    of  salary or  other compensation, or  to afford other  income tax benefits,
    complies with the requirements of the  applicable provisions of the Code  or
    other  laws,  rules  and regulations  required  to provide  such  income tax
    benefits. No prohibited transactions  (as defined in Section  406 or 407  of
    ERISA  or Section  4975 of  the Code)  have occurred  for which  a statutory
    exemption is not available with respect to any KCPL Benefit Plan, and  which
    could  give rise to liability on the part of KCPL, any KCPL Benefit Plan, or
    any fiduciary, party in interest or disqualified person with respect thereto
    that would be  material to  KCPL or  would be material  to KCPL  if it  were
    KCPL's liability.
 
        (d)   LIABILITIES.  With respect to the KCPL Benefit Plans, individually
    and in the aggregate, no event has  occurred, and, to the best knowledge  of
    KCPL,  there does not now exist any  condition or set of circumstances, that
    could subject KCPL or any of the KCPL Subsidiaries to any material liability
    arising under  the  Code, ERISA  or  any other  applicable  law  (including,
    without  limitation, any liability  to any such plan  or the Pension Benefit
    Guaranty Corporation  (the "PBGC")),  or under  any indemnity  agreement  to
    which  KCPL or any of the KCPL  Subsidiaries is a party, excluding liability
    for benefit claims and funding obligations payable in the ordinary course.
 
        (e)  WELFARE PLANS.   None of the KCPL  Benefit Plans that are  "welfare
    plans,"  within  the  meaning of  Section  3(1)  of ERISA,  provide  for any
    benefits with respect to current  or former employees for periods  extending
    beyond  their  retirement  or  other  termination  of  service,  other  than
    continuation coverage required  to be  provided under Section  4980B of  the
    Code or Part 6 of Title I of ERISA.
 
        (f)   DOCUMENTS MADE AVAILABLE.   KCPL has made  available to UCU a true
    and correct copy of  each collective bargaining agreement  to which KCPL  or
    any  of the KCPL Subsidiaries is  a party or under which  KCPL or any of the
    KCPL Subsidiaries has  obligations and,  with respect to  each KCPL  Benefit
    Plan, where applicable, (i) such plan and summary plan description, (ii) the
    most  recent  annual report  filed with  the IRS,  (iii) each  related trust
    agreement, insurance  contract, service  provider or  investment  management
    agreement  (including all amendments  to each such  document), (iv) the most
    recent determination of the IRS with respect to the qualified status of such
    KCPL Benefit Plan, and (v) the most recent actuarial report or valuation.
 
        (g)    PAYMENTS  RESULTING  FROM  THE  MERGERS.    The  consummation  or
    announcement  of  any transaction  contemplated by  this Agreement  will not
    (either alone or upon  the occurrence of any  additional or further acts  or
    events,  including, without limitation, the termination of employment of any
    officers, directors,  employees  or  agents  of KCPL  or  any  of  the  KCPL
    Subsidiaries)  result  in  any  (i) payment  (whether  of  severance  pay or
    otherwise) becoming due from KCPL or any of the KCPL Subsidiaries or, to the
    knowledge of  KCPL,  any  of  the  KCPL  Joint  Ventures,  to  any  officer,
 
                                      A-17
<PAGE>
    employee,  former employee or  director thereof or to  the trustee under any
    "rabbi trust" or similar arrangement, or (ii) benefit under any KCPL Benefit
    Plan being established or becoming accelerated, vested or payable.
 
        (h)  LABOR AGREEMENTS.  As of the Original Execution Date, neither  KCPL
    nor  any of the  KCPL Subsidiaries is  a party to  any collective bargaining
    agreement or other labor agreement with any union or labor organization.  To
    the  best knowledge of KCPL, as of  the Original Execution Date, there is no
    current union representation question involving employees of KCPL or any  of
    the  KCPL Subsidiaries, nor does KCPL know  of any activity or proceeding of
    any labor  organization (or  representative thereof)  or employee  group  to
    organize  any such  employees. Except as  disclosed in the  KCPL SEC Reports
    filed prior to  the Original  Execution Date or  except to  the extent  such
    would  not have a KCPL Material Adverse Effect, (i) there is no unfair labor
    practice, employment discrimination or other material complaint against KCPL
    or any of the KCPL Subsidiaries pending,  or to the best knowledge of  KCPL,
    threatened,  (ii) there is no strike,  lockout or material dispute, slowdown
    or work  stoppage pending  or, to  the best  knowledge of  KCPL,  threatened
    against  or involving KCPL,  and (iii) there is  no proceeding, claim, suit,
    action or governmental investigation  pending or, to  the best knowledge  of
    KCPL,  threatened in  respect of  which any  director, officer,  employee or
    agent of KCPL or any of the KCPL Subsidiaries is or may be entitled to claim
    indemnification  from  KCPL  or  such  KCPL  Subsidiary  pursuant  to  their
    respective  articles  of  incorporation or  by-laws  or as  provided  in the
    indemnification agreements listed in Section 4.10(h) of the KCPL  Disclosure
    Schedule.

    knowledge  of  KCPL,  the KCPL  Joint  Ventures  is in  compliance  with all

    where  the  failure to  so comply  would  not have  a KCPL  Material Adverse
    Effect, and neither KCPL nor any  of the KCPL Subsidiaries has received  any
    communication  (written or oral), from  any person or Governmental Authority
    that alleges that KCPL  or any of  the KCPL Subsidiaries  or the KCPL  Joint
    Ventures  is not in  such compliance with  applicable Environmental Laws. To
    the best knowledge  of KCPL,  compliance with  all applicable  Environmental
    Laws  including,  without  limitation,  all laws  relating  to  the storage,
    handling, use and disposal of nuclear fuel or wastes, will not require  KCPL
    or  any KCPL Subsidiary or, to the knowledge of KCPL, any KCPL Joint Venture
    to incur costs beyond that currently budgeted in the five KCPL fiscal  years
    beginning with January 1, 1996 that will be reasonably likely to result in a
    KCPL Material Adverse Effect, including but not limited to the costs of KCPL
    and  KCPL Subsidiary and  KCPL Joint Venture  pollution control equipment or
    equipment for the  storage, handling,  use or  disposal of  nuclear fuel  or
    wastes, required or known to be required in the future.

    authorizations (collectively, the "ENVIRONMENTAL PERMITS") necessary for the
    construction  of their facilities or the  conduct of their operations except
    where the  failure to  so obtain  would  not have  a KCPL  Material  Adverse
    Effect,  and all such  Environmental Permits are in  good standing or, where
    applicable, a  renewal application  has  been timely  filed and  is  pending
    agency approval, and KCPL and the KCPL Subsidiaries and, to the knowledge of
    KCPL,  the KCPL Joint Ventures are in material compliance with all terms and
    conditions of the Environmental Permits.
 
       (iii) ENVIRONMENTAL CLAIMS.  There is no Environmental Claim (as  defined
    in  SECTION  4.11(C)(I)) which  would have  a  KCPL Material  Adverse Effect
    pending (A)  against  KCPL  or any  of  the  KCPL Subsidiaries  or,  to  the
    knowledge of KCPL, any of the KCPL Joint Ventures, (B) to the best knowledge
    of  KCPL, against any person or entity whose liability for any Environmental
 
                                      A-18
<PAGE>
    Claim KCPL or any of the KCPL Subsidiaries or, to the knowledge of KCPL, any
    of the  KCPL Joint  Ventures has  or  may have  retained or  assumed  either
    contractually  or by operation of  law, or (C) against  any real or personal
    property or operations which KCPL or any of the KCPL Subsidiaries or, to the
    knowledge of KCPL, any of the  KCPL Joint Ventures owns, leases or  manages,

    SECTION 4.11(C)(IV))  of  any  Hazardous Material  (as  defined  in  SECTION
    4.11(C)(III))  that  would be  reasonably likely  to form  the basis  of any
    Environmental Claim against KCPL or any of the KCPL Subsidiaries or the KCPL
    Joint Ventures, or  against any  person or  entity whose  liability for  any
    Environmental  Claim KCPL or any of the  KCPL Subsidiaries or the KCPL Joint
    Ventures has or  may have  retained or  assumed either  contractually or  by
    operation  of law except for any Environmental  Claim which would not have a
    KCPL Material Adverse Effect.
 
        (v)  PREDECESSORS.    KCPL  has  no  knowledge,  with  respect  to   any
    predecessor  of  KCPL or  any of  the  KCPL Subsidiaries  or the  KCPL Joint
    Ventures, of  any  Environmental Claim  which  would have  a  KCPL  Material
    Adverse  Effect  pending  or  threatened, or  of  any  Release  of Hazardous
    Materials that  would  be  reasonably  likely  to  form  the  basis  of  any
    Environmental Claim which would have a KCPL Material Adverse Effect.
 
    (b)  DISCLOSURE.  To KCPL's best knowledge, KCPL has disclosed in writing to
UCU  all facts which KCPL reasonably believes form the basis of an Environmental
Claim which would have a KCPL Material Adverse Effect arising from (i) the  cost

    Section 5.10  EMPLOYEE MATTERS; ERISA.  Except as set forth in Section  5.10
of the UCU Disclosure Schedule:
 
        (a)   BENEFIT  PLANS.   Section 5.10(a)  of the  UCU Disclosure Schedule
    contains a true and complete list of each written or oral material  employee
    benefit  plan, policy or  agreement covering employees,  former employees or
    directors of UCU and each of the UCU Subsidiaries or their beneficiaries, or
    providing benefits to such  persons in respect of  services provided to  any
    such  entity,  including, but  not limited  to,  any employee  benefit plans
    within the meaning of Section 3(3) of  ERISA and any severance or change  in
    control agreement (collectively, the "UCU BENEFIT PLANS").
 
        (b)    CONTRIBUTIONS.   All  material contributions  and  other payments
    required to be made by UCU or any of the UCU Subsidiaries to any UCU Benefit
    Plan (or to any person pursuant to the terms thereof) have been made or  the
    amount  of such payment or contribution obligation has been reflected in the
    UCU Financial Statements.
 
        (c)  QUALIFICATION; COMPLIANCE.  Each of the UCU Benefit Plans  intended
    to  be "qualified" within the meaning of Section 401(a) of the Code has been
    determined by the IRS to be so qualified, and, to the best knowledge of UCU,
    no circumstances exist that are reasonably expected by UCU to result in  the
    revocation  of any such determination. UCU  is in compliance in all material
    respects with, and each of the UCU Benefit Plans is and has been operated in
    all material respects  in compliance  with, all applicable  laws, rules  and
    regulations  governing such  plan, including, without  limitation, ERISA and
    the Code. Each  UCU Benefit  Plan intended to  provide for  the deferral  of
    income,  the reduction of  salary or other compensation,  or to afford other
    income tax  benefits,  complies  with the  requirements  of  the  applicable
    provisions  of the  Code or  other laws,  rules and  regulations required to
    provide such income tax benefits. No prohibited transactions (as defined  in
    Section  406 or 407 of ERISA or Section  4975 of the Code) have occurred for
    which a statutory exemption is not available with respect to any UCU Benefit
    Plan, and which could  give rise to  liability on the part  of UCU, any  UCU
    Benefit  Plan, or  any fiduciary, party  in interest  or disqualified person
    with respect thereto that would be material  to UCU or would be material  to
    UCU if it were UCU's liability.
 
                                      A-26
<PAGE>
        (d)   LIABILITIES.  With respect  to the UCU Benefit Plans, individually
    and in the aggregate, no event has  occurred, and, to the best knowledge  of
    UCU,  there does not now  exist any condition or  set of circumstances, that
    could subject UCU or any of  the UCU Subsidiaries to any material  liability
    arising  under  the  Code, ERISA  or  any other  applicable  law (including,
    without limitation, any liability  to any such plan  or the PBGC), or  under
    any  indemnity agreement to  which UCU or  any of the  UCU Subsidiaries is a
    party, excluding  liability  for  benefit  claims  and  funding  obligations
    payable in the ordinary course.
 
        (e)   WELFARE PLANS.   None of  the UCU Benefit  Plans that are "welfare
    plans," within  the meaning  of  Section 3(1)  of  ERISA, provides  for  any
    benefits  with respect to current or  former employees for periods extending
    beyond  their  retirement  or  other  termination  of  service,  other  than
    continuation  coverage required  to be provided  under Section  4980B of the
    Code or Part 6 of Title I of ERISA.
 
        (f)  DOCUMENTS MADE AVAILABLE.   UCU has made  available to KCPL a  true
    and correct copy of each collective bargaining agreement to which UCU or any
    of  the UCU Subsidiaries  is a party  or under which  UCU or any  of the UCU
    Subsidiaries has obligations  and, with  respect to each  UCU Benefit  Plan,
    where  applicable, (i) such plan and summary plan description, (ii) the most
    recent annual report filed with the IRS, (iii) each related trust agreement,
    insurance contract,  service  provider or  investment  management  agreement
    (including  all  amendments to  each such  document),  (iv) the  most recent
    determination of the IRS  with respect to the  qualified status of such  UCU
    Benefit Plan, and (v) the most recent actuarial report or valuation.
 
        (g)    PAYMENTS  RESULTING  FROM  THE  MERGERS.    The  consummation  or
    announcement of  any transaction  contemplated by  this Agreement  will  not
    (either  alone or upon the  occurrence of any additional  or further acts or
    events, including, without limitation, the termination of employment of  any
    officers,  directors,  employees  or  agents  of  UCU  or  any  of  the  UCU
    Subsidiaries) result  in  any  (i)  payment (whether  of  severance  pay  or
    otherwise)  becoming due from UCU or any  of the UCU Subsidiaries or, to the
    knowledge of UCU, any of the  UCU Joint Ventures, to any officer,  employee,
    former  employee  or director  thereof or  to the  trustee under  any "rabbi
    trust" or similar arrangement,  or (ii) benefit under  any UCU Benefit  Plan
    being established or becoming accelerated, vested or payable.
 
        (h)   LABOR AGREEMENTS.  As of  the Original Execution Date, neither UCU
    nor any of  the UCU  Subsidiaries is a  party to  any collective  bargaining
    agreement  or other labor agreement with any union or labor organization. To
    the best knowledge of UCU,  as of the Original  Execution Date, there is  no
    current  union representation question involving employees  of UCU or any of
    the UCU Subsidiaries, nor does UCU know of any activity or proceeding of any
    labor organization (or representative thereof) or employee group to organize
    any such employees. Except as disclosed  in the UCU SEC Reports filed  prior
    to the Original Execution Date or except to the extent such would not have a
    UCU  Material  Adverse  Effect,  (i)  there  is  no  unfair  labor practice,
    employment discrimination or other material complaint against UCU or any  of
    the  UCU Subsidiaries pending, or to  the best knowledge of UCU, threatened,
    (ii) there  is no  strike, lockout  or material  dispute, slowdown  or  work
    stoppage  pending or,  to the best  knowledge of UCU,  threatened against or
    involving UCU, and  (iii) there  is no  proceeding, claim,  suit, action  or
    governmental  investigation  pending  or,  to  the  best  knowledge  of UCU,
    threatened in respect of which any  director, officer, employee or agent  of
    UCU  or  any  of  the  UCU  Subsidiaries is  or  may  be  entitled  to claim
    indemnification from UCU or such UCU Subsidiary pursuant to their respective
    articles of incorporation or by-laws  or as provided in the  indemnification
    agreements listed in Section 5.10(h) of the UCU Disclosure Schedule.

    Section 5.11  ENVIRONMENTAL PROTECTION.
 
    (a) Except as set forth in Section 5.11 of the UCU Disclosure Schedule or in
the UCU SEC Reports filed prior to the Original Execution Date:
 
        (i)  COMPLIANCE.   UCU  and each  of  the UCU  Subsidiaries and,  to the
    knowledge of  UCU,  the  UCU  Joint  Ventures  is  in  compliance  with  all
    applicable  Environmental Laws except  where the failure  to so comply would
    not have a UCU Material Adverse Effect,  and neither UCU nor any of the  UCU
    Subsidiaries  has  received any  communication (written  or oral),  from any
    person or Governmental  Authority that alleges  that UCU or  any of the  UCU
    Subsidiaries  or  the UCU  Joint  Ventures is  not  in such  compliance with
    applicable Environmental Laws. To the best knowledge of UCU, compliance with
    all applicable Environmental Laws will not require UCU or any UCU Subsidiary
    or, to the knowledge  of UCU, any  UCU Joint Venture  to incur costs  beyond
    that  currently budgeted in the five UCU fiscal years beginning with January
    1, 1996 that will be reasonably likely  to result in a UCU Material  Adverse
    Effect, including but not limited to the costs of UCU and UCU Subsidiary and
    UCU  Joint  Venture  pollution control  equipment  required or  known  to be
    required in the future.
 
        (ii) ENVIRONMENTAL PERMITS.  UCU and  each of the UCU Subsidiaries  and,
    to  the knowledge of UCU, the UCU Joint Ventures has obtained or has applied
    for all the Environmental  Permits necessary for  the construction of  their
    facilities or the conduct of their operations except where the failure to so
    obtain  would  not  have  a  UCU  Material  Adverse  Effect,  and  all  such
    Environmental Permits are in good  standing or, where applicable, a  renewal
    application  has been timely  filed and is pending  agency approval, and UCU
    and the  UCU  Subsidiaries and,  to  the knowledge  of  UCU, the  UCU  Joint
    Ventures  are in  material compliance with  all terms and  conditions of the
    Environmental Permits.
 
       (iii) ENVIRONMENTAL CLAIMS.  There is no Environmental Claim which  would
    have a UCU Material Adverse Effect pending (A) against UCU or any of the UCU
    Subsidiaries or, to the knowledge of UCU, any of the UCU Joint Ventures, (B)
    to  the best knowledge of UCU, against  any person or entity whose liability
    for any Environmental Claim UCU  or any of the  UCU Subsidiaries or, to  the
    knowledge  of UCU, any of the UCU Joint Ventures has or may have retained or
    assumed either contractually or by operation of law, or (C) against any real
    or personal property or operations which UCU or any of the UCU  Subsidiaries
    or,  to the knowledge of UCU, any of  the UCU Joint Ventures owns, leases or
    manages, in whole or in part.
 
       (iv) RELEASES.   UCU has no  knowledge of any  Releases of any  Hazardous
    Material  that  would  be  reasonably  likely  to  form  the  basis  of  any
    Environmental Claim against UCU  or any of the  UCU Subsidiaries or the  UCU
    Joint  Ventures, or  against any  person or  entity whose  liability for any
    Environmental Claim UCU  or any  of the UCU  Subsidiaries or  the UCU  Joint
    Ventures  has or  may have  retained or  assumed either  contractually or by
    operation of law except for any  Environmental Claim which would not have  a
    UCU Material Adverse Effect.
 
        (v) PREDECESSORS.  UCU has no knowledge, with respect to any predecessor
    of  UCU or  any of the  UCU Subsidiaries or  the UCU Joint  Ventures, of any
    Environmental Claim which would have  a UCU Material Adverse Effect  pending
    or  threatened,  or of  any  Release of  Hazardous  Materials that  would be
    reasonably likely to form the basis  of any Environmental Claim which  would
    have a UCU Material Adverse Effect.
 
    (b)   DISCLOSURE.  To UCU's best  knowledge, UCU has disclosed in writing to
KCPL all facts which UCU reasonably believes form the basis of an  Environmental
Claim  which would have a UCU Material  Adverse Effect arising from (i) the cost
of UCU pollution control equipment currently required or known to be required in
the future, (ii) current UCU remediation costs or UCU remediation costs known to
be required in the future or (iii) any other environmental matter affecting UCU.

of any class or series  of the capital stock of  UCU or any of its  Subsidiaries
required  to  approve this  Agreement, the  Mergers  and the  other transactions
contemplated hereby.
 
    Section 5.14  ACCOUNTING MATTERS.  Neither UCU nor, to UCU's best knowledge,
any of its Affiliates has taken or agreed to take any action that would  prevent
the  Surviving Corporation from  accounting for the  transactions to be effected
pursuant to this Agreement as a pooling of interests in accordance with GAAP and
applicable SEC regulations.
 
    Section 5.15   ARTICLE EIGHT  OF UCU'S  CERTIFICATE OF  INCORPORATION.   The
provisions  of Article  Eight of  UCU's Certificate  of Incorporation  will not,
prior to  the  termination of  this  Agreement,  assuming the  accuracy  of  the
representation contained in Section 4.18 (without giving effect to the knowledge
qualification  thereof),  apply  to  this  Agreement,  the  Mergers  or  to  the
transactions contemplated hereby.
 
    Section 5.16  OPINION OF FINANCIAL ADVISOR.  UCU has received the opinion of

insurers in such amounts and against such  risks and losses as are customary  in
all  material respects for companies conducting the business as conducted by UCU
and the UCU Subsidiaries during such time period. Except as set forth in Section
5.17 of the UCU Disclosure Schedule, neither UCU nor any of the UCU Subsidiaries
has received  any notice  of cancellation  or termination  with respect  to  any
material  insurance policy of UCU or any  of the UCU Subsidiaries. The insurance
policies of  UCU and  each of  the UCU  Subsidiaries are  valid and  enforceable
policies in all material respects.
 
    Section  5.18   UCU  NOT  AN INTERESTED  SHAREHOLDER.   As  of  the Original
Execution Date,  neither  UCU nor,  to  its  reasonable knowledge,  any  of  its
Affiliates,  is an "Interested  Shareholder" as such term  is defined in Article

    cause  its respective Subsidiaries to,  carry on their respective businesses
    in the usual, regular and ordinary  course in substantially the same  manner
    as  heretofore  conducted and  use  all commercially  reasonable  efforts to
    preserve intact their present business organizations and goodwill,  preserve
    the  goodwill and relationships with  customers, suppliers and others having
    business dealings with them and, subject to prudent management of work force
    needs and ongoing programs currently  in force, keep available the  services
    of  their present  officers and  employees, provided,  however, that nothing
    shall prohibit either  party or  any of its  Subsidiaries from  transferring
    operations  to such party or any of its wholly owned Subsidiaries. Except as
    set forth  in Section  6.1(a) of  the KCPL  Disclosure Schedule  or  Section

    KCPL, to KCPL and the KCPL Subsidiaries taken as a whole, and in the case of
    UCU,  to UCU and the  UCU Subsidiaries taken as  a whole; provided, however,
    that  notwithstanding  the  above,  a   party  or  any  of  its   respective

    respect of, in  lieu of,  or in substitution  for, shares  of their  capital
    stock  or (iii) redeem, repurchase or  otherwise acquire any shares of their
    capital  stock,  other  than  (A)  redemptions,  purchases  or  acquisitions
    required  by the respective terms  of any series of  KCPL Preferred Stock or

    accordance with GAAP and applicable  SEC regulations, and each party  hereto
    shall  use all reasonable  efforts to achieve  such result (including taking

<PAGE>
    Joint Ventures, or, in the case of  KCPL, the KCPL Joint Ventures, on  terms
    materially less favorable to such party than could be reasonably expected to
    have  been  obtained with  an unaffiliated  third-party  on an  arm's length
    basis.
 
        (o)   COOPERATION, NOTIFICATION.    Each party  shall  (i) confer  on  a
    regular  and frequent  basis with one  or more representatives  of the other
    party to discuss,  subject to applicable  law, material operational  matters
    and  the general status of its  ongoing operations, (ii) promptly notify the
    other party of any significant changes in its business, properties,  assets,
    condition  (financial or other),  results of operations  or prospects, (iii)
    promptly advise the other  party of any  change or event  which has had  or,

    UCU Material Adverse Effect and (iv)  promptly provide the other party  with
    copies of all filings made by such party or any of its Subsidiaries with any
    state   or  federal  court,  administrative   agency,  commission  or  other
    Governmental  Authority   in  connection   with  this   Agreement  and   the
    transactions contemplated hereby.
 
        (p)   RATE  MATTERS.  Subject  to applicable  law, each of  KCPL and UCU
    shall, and  shall cause  its respective  Subsidiaries to,  discuss with  the
    other  any changes  in its  or its  Subsidiaries' rates  or the  services it
    provides or charges (other than pass-through fuel and gas rates or charges),
    standards of service  or accounting  from those  in effect  on the  Original
    Execution Date and consult with the other prior to making any filing (or any
    amendment  thereto), or effecting any  agreement, commitment, arrangement or
    consent with governmental  regulators, whether  written or  oral, formal  or
    informal,  with respect thereto, and no party will make any filing to change
    its rates or the services it provides on file with the FERC that would  have
    a  material  adverse effect  on the  benefits  associated with  the business
    combination provided for herein.
 
        (q)  THIRD-PARTY CONSENTS.  KCPL shall, and shall cause its Subsidiaries

        (r)  NO BREACH, ETC.  No party shall, nor shall any party permit any  of
    its  Subsidiaries to, willfully take any  action that would or is reasonably
    likely to result in a material breach of any provision of this Agreement  or
    in  any of  its representations and  warranties set forth  in this Agreement
    being untrue on and as of the Closing Date.
 
        (s)  TAX-EXEMPT STATUS.  No party shall, nor shall any party permit  any
    Subsidiary   to,  take   any  action   that  would   likely  jeopardize  the
    qualification of KCPL's or UCU's outstanding revenue bonds which qualify  on
    the  Original Execution  Date under  Section 142(a)  of the  Code as "exempt
    facility bonds" or as tax-exempt industrial development bonds under  Section
    103(b)(4) of the Internal Revenue Code of 1954, as amended, prior to the Tax
    Reform Act of 1986.
 
        (t)   TRANSITION MANAGEMENT.  As  soon as practicable after the Original

    consistent with past practice, modify, amend,
 
                                      A-33
<PAGE>
    terminate,  renew or  fail to use  reasonable business efforts  to renew any
    material contract or agreement to which such party or any Subsidiary of such
    party is a party or waive, release or assign any material rights or claims.
 
        (v)  INSURANCE.  Each party shall, and shall cause its Subsidiaries  to,
    maintain  with financially responsible insurance companies insurance in such
    amounts and against  such risks and  losses as are  customary for  companies
    engaged  in the electric  and gas utility industry  and employing methods of
    generating electric power and fuel sources similar to those methods employed
    and fuels used by such party or its Subsidiaries.
 
        (w)  PERMITS.   Each party shall, and  shall cause its Subsidiaries  to,
    use  reasonable  efforts to  maintain  in effect  all  existing governmental
    permits  which  are  material  to  the  operations  of  such  party  or  its
    Subsidiaries.

    Disclosure Schedule  or  Section  6.1(x) of  the  UCU  Disclosure  Schedule,
    neither  party  shall (i)  make or  rescind any  material express  or deemed
    election relating to  taxes unless  such election  will have  the effect  of
    minimizing  the tax liabilities  of KCPL or  UCU or any  of their respective
    Subsidiaries,  including  elections   for  any  and   all  joint   ventures,
    partnerships,  limited  liability  companies,  working  interests  or  other
    investments where  KCPL  or  UCU  has the  capacity  to  make  such  binding
    elections,  (ii)  settle or  compromise  any material  claim,  action, suit,
    litigation, proceeding,  arbitration,  investigation, audit  or  controversy
    relating  to taxes  unless such  settlement or  compromise results  in (A) a
    change in  taxable income  or  tax liability  that  will reverse  in  future
    periods and is therefore, by its nature, a timing difference or (B) a change
    in  taxable income or tax liability that  will not reverse in future periods
    and is  therefore, by  its nature,  a permanent  difference unless  the  tax
    liability  resulting from  the increase  is less  than $1  million, or (iii)
    change in any  material respect any  of its methods  of reporting income  or
    deductions  for  federal  income tax  purposes  from those  employed  in the
    preparation of its  federal income tax  return for the  taxable year  ending
    December 31, 1994, except as may be required by applicable law or except for
    such  changes  that  would  reduce consolidated  federal  taxable  income or
    alternative minimum taxable income.
 
        (y)  DISCHARGE  OF LIABILITIES.   No party  shall, nor  shall any  party
    permit  any of its respective Subsidiaries to, pay, discharge or satisfy any
    material claims, liabilities or obligations (absolute, accrued, asserted  or
    unasserted,  contingent or otherwise), other  than the payment, discharge or
    satisfaction, in  the  ordinary  course of  business  consistent  with  past
    practice (which includes the payment of final and unappealable judgments) or
    in accordance with their terms, of liabilities reflected or reserved against
    in,  or contemplated by,  the most recent  consolidated financial statements
    (or the notes thereto) of such party included in such party's reports  filed
    with the SEC, or incurred in the ordinary course of business consistent with
    past practice.

Statement shall be true and correct in all material respects without omission of
any  material  fact which  is required  to  make such  information not  false or
misleading. No representation, covenant or agreement is made by any party hereto
with respect to  information supplied by  any other party  for inclusion in  the
Joint Proxy Statement/Registration Statement.

such  loss,  expense,  claim,  damage  or  liability  (whether  or  not  arising
 
                                      A-36
<PAGE>
before  the  Effective  Time),  (i)  the  Surviving  Corporation  shall  pay the
reasonable fees and  expenses of  counsel selected by  the Indemnified  Parties,
which  counsel shall  be reasonably  satisfactory to  the Surviving Corporation,
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  MGCL, (ii)  the
Surviving Corporation will 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 MGCL and  the
Restated Articles of Consolidation or by-laws of the Surviving Corporation shall
be  made by independent counsel mutually acceptable to the Surviving Corporation
and the Indemnified  Party; PROVIDED,  HOWEVER, that  the Surviving  Corporation
shall  not be  liable for  any settlement  effected without  its written consent
(which consent shall not be unreasonably withheld). 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.
 
    (b)   INSURANCE.   For a period of  six years after  the Effective Time, the
Surviving Corporation  shall  cause  to  be maintained  in  effect  policies  of
directors  and officers' liability insurance maintained  by KCPL and UCU for the
benefit of those persons who are currently covered by such policies on terms  no
less  favorable than  the terms  of such  current insurance  coverage; PROVIDED,
HOWEVER, that the Surviving Corporation shall  not be required to expend in  any
year an amount in excess of 200% of the annual aggregate premiums currently paid
by  KCPL and UCU for  such insurance; and PROVIDED,  FURTHER, that if the annual
premiums  of  such  insurance  coverage   exceed  such  amount,  the   Surviving
Corporation  shall  be  obligated to  obtain  a  policy with  the  best coverage
available, in the reasonable judgment of the Board of Directors of the Surviving
Corporation, for a cost not exceeding such amount.
 
    (c)  SUCCESSORS.   In  the event  the Surviving  Corporation or  any of  its
successors  or assigns (i) consolidates with or  merges into any other person or
entity and shall  not be the  continuing or surviving  corporation or entity  of
such  consolidation or merger or (ii) transfers  all or substantially all of its
properties and assets to  any person or  entity, then and  in either such  case,
proper  provisions  shall be  made so  that  the successors  and assigns  of the
Surviving Corporation shall  assume the  obligations set forth  in this  Section
7.5.
 
    (d)   SURVIVAL OF INDEMNIFICATION.  To  the fullest extent permitted by law,
from and after the Effective Time, all rights to indemnification as of the  date
hereof  in favor of the  employees, agents, directors and  officers of KCPL, UCU
and their respective Subsidiaries with respect to their activities as such prior
to the Effective Time, as provided in their respective articles of incorporation
and by-laws in effect on  the date thereof, or otherwise  in effect on the  date
hereof,  shall survive the Mergers  and shall continue in  full force and effect
for a period of not less than six years from the Effective Time.
 
    (e)  BENEFIT.  The provisions of this Section 7.5 are intended to be for the
benefit of, and  shall be  enforceable by, each  Indemnified Party,  his or  her
heirs and his or her representatives.
 
    Section  7.6   PUBLIC  ANNOUNCEMENTS.   Subject  to each  party's disclosure
obligations imposed by law, KCPL and UCU  will cooperate with each other in  the
development  and distribution of all news  releases and other public information
disclosures  with  respect  to  this  Agreement  or  any  of  the   transactions
contemplated  hereby and  shall not issue  any public  announcement or statement
with respect hereto  or thereto without  the consent of  the other party  (which
consent shall not be unreasonably withheld).
 
    Section  7.7  RULE 145  AFFILIATES.  UCU shall identify  in a letter to KCPL
all persons who  are, and to  UCU's best knowledge  who will be  at the  Closing
Date,  "affiliates" of UCU as such term is used in Rule 145 under the Securities
Act (or  otherwise under  applicable  SEC accounting  releases with  respect  to
pooling-of-interests accounting treatment). UCU shall use all reasonable efforts
to cause its
 
                                      A-37
<PAGE>
affiliates  (including  any person  who may  be  deemed to  have become  such an
affiliate after the date  of the letter  referred to in  the prior sentence)  to
deliver   to  KCPL  on  or  prior  to  the  Closing  Date  a  written  agreement
substantially  in  the  form  attached  as  EXHIBIT  7.7  (each,  an  "AFFILIATE
AGREEMENT").
 
    Section 7.8  EMPLOYEE AGREEMENTS AND WORKFORCE MATTERS.
 
    (a)   CERTAIN  EMPLOYEE AGREEMENTS.   Subject to Section  7.9, Section 7.10,
Section 7.13 and Section  7.14, the Surviving  Corporation and its  Subsidiaries
shall   honor,  without  modification,  all  contracts,  agreements,  collective
bargaining agreements and commitments  of the parties prior  to the date  hereof
that  apply to any current  or former employee or  current or former director of
the parties hereto; PROVIDED, HOWEVER, that this undertaking is not intended  to
prevent  the Surviving  Corporation from  enforcing such  contracts, agreements,
collective bargaining agreements and commitments in accordance with their terms,
including, without limitation,  any reserved  right to  amend, modify,  suspend,
revoke   or  terminate  any  such  contract,  agreement,  collective  bargaining
agreement or commitment.
 
    (b)   WORKFORCE  MATTERS.    Subject  to  applicable  collective  bargaining
agreements, for a period of 3 years following the Effective Time, any reductions
in  workforce in respect of employees of the Surviving Corporation shall be made
on a fair  and equitable basis,  without regard to  whether employment was  with
KCPL  or the KCPL Subsidiaries or UCU  or the UCU Subsidiaries, and any employee
whose employment is terminated or job is eliminated by the Surviving Corporation
or any of its Subsidiaries during  such period shall be entitled to  participate
on  a fair and equitable  basis in the job  opportunity and employment placement
programs offered by the  Surviving Corporation or any  of its Subsidiaries.  Any
workforce  reductions carried out following the  Effective Time by the Surviving
Corporation and its Subsidiaries shall be done in accordance with all applicable
collective bargaining  agreements and  all laws  and regulations  governing  the
employment  relationship and termination  thereof including, without limitation,
the  Worker  Adjustment   and  Retraining  Notification   Act  and   regulations
promulgated thereunder, and any comparable state or local law.
 
    Section 7.9  EMPLOYEE BENEFIT PLANS.
 
    (a)   COMPANY  PLANS.  KCPL  and UCU agree  to cooperate and  agree upon the
employee  benefits  plans  and  programs   to  be  provided  by  the   Surviving
Corporation.
 
    (b)   EFFECT OF THE  MERGERS.  The consummation of  the Mergers shall not be
treated as a termination of employment for  purposes of any UCU Benefit Plan  or
KCPL Benefit Plan.
 
    (c)   UCU SUPPLEMENTAL CONTRIBUTORY PLAN.  The UCU Supplemental Contributory
Retirement Plan shall be revised to  provide that, from and after the  Effective
Time,  the reference to "UCU COMMON SHARES"  shall instead refer to "KCPL COMMON
STOCK."
 
    (d)   CREDIT  FOR  PAST  SERVICE.    Without  limitation  of  the  foregoing
provisions of this Section 7.9, each participant of any KCPL Benefit Plan or UCU
Benefit   Plan  shall  receive  credit  for   purposes  of  (i)  eligibility  to
participate, vesting and eligibility to receive benefits under any benefit  plan
of  the  Surviving Corporation  or any  of its  subsidiaries or  affiliates that
replaces a KCPL Benefit  Plan or a  UCU Benefit Plan,  and (ii) benefit  accrual
under  any  severance  or  vacation  pay  plan,  for  service  credited  for the
corresponding purpose  under  such  KCPL  Benefit  Plan  or  UCU  Benefit  Plan;
provided, however, that such crediting of service shall not operate to duplicate
any benefit to any such participant or the funding for any such benefit.
 
    (e)   ADOPTION OF SURVIVING CORPORATION  REPLACEMENT PLANS.  With respect to
the KCPL annual incentive plan (the  "KCPL INCENTIVE PLAN"), the UCU annual  and
long-term  incentive  plan  (the  "UCU  INCENTIVE  PLAN"),  the  KCPL  long-term
incentive plan (the  "KCPL INCENTIVE STOCK  PLAN") and the  UCU stock  incentive
plan  (the  "UCU  INCENTIVE  STOCK PLAN"),  the  Surviving  Corporation  and its
subsidiaries shall adopt replacement plans as  set forth in this Section  7.9(e)
(collectively,  the  "SURVIVING  CORPORATION  REPLACEMENT  PLANS").  Subject  to
shareholder approval thereof by the KCPL shareholders and the UCU  shareholders,
the   Surviving   Corporation   Replacement   Plans   shall   go   into   effect
 
                                      A-38
<PAGE>
at the  Effective Time.  Upon the  consummation of  the Mergers,  no  additional
obligations  shall be incurred under the  KCPL Incentive Plan, the UCU Incentive
Plan, the KCPL Stock Incentive Plan or  the UCU Incentive Stock Plan, except  to
the  extent  such  obligations  are  attributable  to  employment  prior  to the
Effective Time and are consistent with past practice under the applicable  plan.
The  KCPL Incentive Plan  and the UCU  Incentive Plan shall  be replaced (except
with respect to obligations incurred or attributable to employment prior to  the
Effective Time) by a new annual bonus plan (the "SURVIVING CORPORATION INCENTIVE
PLAN") under which bonuses, based on percentages of base salaries and payable in
cash,  shares of KCPL  Common Stock or such  form as shall  be determined by the
Compensation Committee of the  Board of Directors  of the Surviving  Corporation
(the  "COMMITTEE"), are awarded based upon  the achievement of performance goals
determined in advance by  the Committee. With respect  to those participants  in
the  Surviving  Corporation  Incentive  Plan  who  are,  or  who  the  Committee
determines are likely to be, "covered  employees" within the meaning of  Section
162(m)  of the Code, whose compensation is likely to exceed the amount specified
in Code Section 162(m)(1),  the performance goals  shall be objective  standards
that  are  approved  by shareholders  in  accordance with  the  requirements for
exclusion  from   the   limitations  of   Section   162(m)  of   the   Code   as
performance-based  compensation.  The  KCPL  Incentive Stock  Plan  and  the UCU
Incentive Stock  Plan shall  be  replaced (except  with respect  to  obligations
incurred  or attributable to employment prior to  the Effective Time) by a stock
compensation plan  (the  "SURVIVING  CORPORATION  STOCK  PLAN").  The  Surviving
Corporation  Stock  Plan shall  provide for  the grant  of stock  options, stock
appreciation rights, restricted stock and such other awards based upon the  KCPL
Common  Stock as the Committee may determine, subject to shareholder approval of
the Surviving Corporation Stock Plan. The Surviving Corporation shall reserve an
appropriate number of shares for issuance under the Surviving Corporation  Stock
Plan.
 
    (f)  KCPL AND UCU ACTION.  With respect to each of the Surviving Corporation
Replacement  Plans,  each  of  KCPL  and UCU  shall  take  all  corporate action
necessary or appropriate to obtain the approval of their respective shareholders
with respect to such plan prior to the Effective Time.
 
    Section 7.10  STOCK OPTION AND OTHER STOCK PLANS.
 
    (a)  UCU STOCK  OPTIONS.  As of  the Effective Time, each  of the UCU  Stock
Options  which is outstanding as  of the UCU Effective  Time shall be assumed by
the Surviving Corporation  and converted  into an  option (or  a new  substitute
option  shall be granted) to purchase the  number of shares of KCPL Common Stock
(rounded up to the  nearest whole share)  equal to the number  of shares of  UCU
Common  Stock subject to such  option multiplied by the  Conversion Ratio, at an
exercise price  per share  of KCPL  Common Stock  (rounded down  to the  nearest
penny)  equal to the former  exercise price per share  of UCU Common Stock under
such option  immediately  prior  to  the  UCU  Effective  Time  divided  by  the
Conversion Ratio; PROVIDED, HOWEVER, that in the case of any UCU Stock Option to
which  Section 421  of the  Code applies  by reason  of its  qualification under
Section 422 of the Code, the conversion formula shall be adjusted, if necessary,
to comply  with  Section 424(a)  of  the Code.  Except  as provided  above,  the
converted  or substituted UCU Stock  Options shall be subject  to the same terms
and conditions  (including, without  limitation,  expiration date,  vesting  and
exercise  provisions) as were applicable to  UCU Stock Options immediately prior
to the  UCU  Effective  Time,  except  that  the  acceleration  of  vesting  and
exercisability  as  a result  of  the Mergers  shall  not be  given  effect. For
purposes of such terms and  conditions, the Mergers shall  not be treated as  an
event  which shall affect the period for exercising UCU Stock Options. UCU Stock
Options shall not be treated as expiring as of the UCU Effective Time solely due
to the fact that UCU shall cease to exist as of the Effective Time.
 
    (b)  KCPL STOCK OPTIONS.  The Mergers shall not be treated as an event which
shall cause the acceleration of vesting and exercisability of KCPL Stock Options
or affect the period for exercising KCPL Stock Options.
 
    (c)  OTHER UCU STOCK AWARDS.  Each outstanding award under the UCU Incentive
Stock Plan  other than  the UCU  Stock Options  (the "UCU  STOCK AWARDS")  shall
constitute an award based upon the same number of shares of KCPL Common Stock as
the holder of such UCU Stock Award would
 
                                      A-39
<PAGE>
have been entitled to receive pursuant to the Mergers in accordance with Article
II  hereof had such holder  been the absolute owner,  immediately before the UCU
Effective Time, of the shares of UCU Common Stock on which such UCU Stock  Award
is  based, and otherwise on  the same terms and  conditions as governed such UCU
Stock  Award  immediately  before  the   UCU  Effective  Time  (the   "SURVIVING
CORPORATION STOCK AWARDS"). At the UCU Effective Time, the Surviving Corporation
shall  assume each agreement  relating to the  UCU Stock Awards. Notwithstanding
the foregoing, this paragraph shall not be construed, interpreted or applied  so
as to cause a duplication of any benefit to any individual.
 
    (d)    SURVIVING  CORPORATION ACTION.    As  soon as  practicable  after the
Effective Time, the Surviving  Corporation shall deliver to  the holders of  UCU
Stock  Options  and  UCU Stock  Awards  appropriate notices  setting  forth such
holders' rights pursuant to the  Surviving Corporation Stock Plan and  Surviving
Corporation  Stock Awards (the "SURVIVING  CORPORATION STOCK BENEFITS") and each
underlying stock award agreement, each as assumed by the Surviving  Corporation.
As  soon as practicable after the  Effective Time the Surviving Corporation will
cause to be filed one  or more registration statements on  Form S-3 or Form  S-8
under the Securities Act (or any successor or other appropriate forms), in order
to  register the  shares of  KCPL Common Stock  issuable in  connection with the
Surviving Corporation Stock  Benefits, and the  Surviving Corporation shall  use
its  best efforts to maintain the  effectiveness of such registration statements
(and maintain the current status of  the prospectuses contained therein) for  so
long  as  such  benefits  and  grants remain  payable  and  such  options remain
outstanding. At or prior  to the UCU Effective  Time, the Surviving  Corporation
shall  take all corporate action necessary  to reserve for issuance a sufficient
number of  shares of  KCPL Common  Stock  for delivery  in connection  with  the
Surviving  Corporation Stock Benefits. The  Surviving Corporation shall take all
corporate action necessary  or appropriate  to (i)  obtain shareholder  approval
with  respect to  the Surviving  Corporation Stock  Benefits to  the extent such
approval is required for purposes of the  Code or other applicable law, or  (ii)
enable  any plan pursuant to which such  benefits are issued to comply with Rule
16b-3 promulgated under the Exchange Act. With respect to those individuals  who
subsequent  to the Mergers  will be subject to  the reporting requirements under
Section 16(a)  of the  Exchange Act  with respect  to equity  securities of  the
Surviving Corporation, the Surviving Corporation shall administer such Surviving
Corporation  Stock Benefits,  where applicable, in  a manner  that complies with
Rule 16b-3 promulgated under the Exchange Act.
 
    Section 7.11  NO SOLICITATIONS.   From and after  the date hereof, KCPL  and
UCU  will  not,  and  will  not authorize  or  permit  any  of  their respective
Representatives to,  directly  or  indirectly, solicit,  initiate  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  herein) from  any person, or  engage in any  discussion or negotiations
relating thereto or  accept any  Acquisition Proposal;  PROVIDED, HOWEVER,  that
notwithstanding  any other provision hereof, the respective party may (i) at any
time prior to the time the  respective party's stockholders shall have voted  to
approve  this 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  the date hereof)  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
Mergers  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 shall  conclude 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
 
                                      A-40
<PAGE>
reasonably  customary  form  on  terms  not  in  the  aggregate  materially more
favorable  to  such  person   or  entity  than  the   terms  contained  in   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 this Agreement pursuant to  Section 9.1(e) or 9.1(f), as  applicable.
Each  party  shall immediately  cease and  terminate any  existing solicitation,
initiation, encouragement, activity, discussion or negotiation with any  parties
conducted  heretofore by  the party or  its Representatives with  respect to the
foregoing. Each party hereto shall notify the other party orally and in  writing
of  any such inquiries, offers or  proposals (including, without limitation, the
terms and conditions of any such proposal and the identify 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" shall mean  a proposal or
offer (other  than by  another party  hereto) for  a tender  or exchange  offer,
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.
 
    Section 7.12   SURVIVING  CORPORATION  BOARD OF  DIRECTORS.   The  Board  of
Directors  of KCPL  will take  such action  as may  be necessary  (including the
amendment of the KCPL by-laws) to  cause the number of directors comprising  the
full Board of Directors of KCPL immediately prior to or at the Effective Time to
be  18 persons, 9 of whom shall be  the then existing directors of KCPL prior to
the Effective  Time and  9 of  whom  shall be  designated by  UCU prior  to  the
Effective  Time. If, prior  to the Effective  Time, any of  such designees shall

    transferred  or  reissued  to the  Surviving  Corporation at  or  before the

    immediately after the UCU Effective Time.

    the  United States  or any  state shall  have issued  an order,  judgment or
    decree permanently  restraining,  enjoining  or  otherwise  prohibiting  the
    Mergers,  and such  order, judgment  or decree  shall have  become final and

Attention: Drue Jennings
        Chairman of the Board and President
 
Gentlemen and Madam:
 
    Kansas  City  Power &  Light Company  (the "Company"),  KC Merger  Sub, Inc.
("Sub"), UtiliCorp United Inc. (the "Merger  Partner") and KC United Corp.  have
entered  into an Amended and  Restated Agreement and Plan  of Merger dated as of
January 19, 1996, as amended and restated as of May 20, 1996 (the  "Agreement"),
pursuant  to which  (i) Sub will  merge with  and into Merger  Partner, with the
Merger Partner surviving  (the "UCU Merger"),  and (ii) immediately  thereafter,
the  surviving  corporation in  the  UCU Merger  will  merge with  and  into the
Company,  with  the  Company  surviving  (together  with  the  UCU  Merger,  the
"Mergers").  In the  Mergers, (a)  each issued  and outstanding  share of common
stock, par value  $1.00 per share,  of the Merger  Partner (the "Merger  Partner
Shares"),  (other than the Merger Partner Shares  owned by the Merger Partner or
by any wholly-owned subsidiary of the Merger Partner, or by the Company, all  of
which shall be canceled and retired) will be converted into the right to receive
1.0  share (the  "Exchange Ratio")  of the  Company's common  stock, without par
value (the "Company Shares"), and (b)  each issued and outstanding share of  the
Company  Shares  shall  remain  outstanding.  The  Mergers  are  expected  to be
considered by the shareholders of the Company and the Merger Partner at separate
shareholder's meetings in August 1996.
 
    You have  asked us  whether, in  our opinion,  the proposed  Exchange  Ratio
pursuant to the proposed Mergers is fair to the holders of Company Shares (other
than the Merger Partner and its affiliates) from a financial point of view.
 
    In arriving at the opinion set forth below, we have, among other things:
 
    (1)  Reviewed the Company's Annual Reports, Forms 10-K and related financial
       information for the five fiscal years  ended December 31, 1995, and  Form
       10-Q  and the related  unaudited financial information  for the quarterly
       period ending March 31, 1996;
 
    (2) Reviewed the  Merger Partner's  Annual Reports, Forms  10-K and  related
       financial  information for the five fiscal years ended December 31, 1995,
       and Form 10-Q  and the  related unaudited financial  information for  the
       quarterly period ending March 31, 1996;
 
    (3) Reviewed certain information, including financial forecasts, relating to
       the  business, earnings, cash  flow, assets and  prospects of the Company
       and the Merger  Partner, furnished to  us by the  Company and the  Merger
       Partner;
 
    (4)  Conducted discussions with members of  senior management of the Company
       and the Merger Partner concerning their respective businesses, regulatory
       environments, prospects and strategic objectives and possible  operating,
       administrative  and  capital synergies  which might  be realized  for the
       combined companies following the Mergers;
 
    (5) Reviewed  the historical  market  prices and  trading activity  for  the
       Company  Shares and the Merger Partner Shares and compared them with that
       of certain publicly  traded companies  which we deemed  to be  reasonably
       similar to the Company and the Merger Partner, respectively;
 
    (6) Compared the results of operations of the Company and the Merger Partner
       with  that of certain companies which  we deemed to be reasonably similar
       to the Company and the Merger Partner, respectively;
 
    (7) Analyzed the  relative valuation of  the Company Shares  and the  Merger
       Partner  Shares  using various  valuation  methodologies which  we deemed
       appropriate;
 
                                      B-1
<PAGE>
    (8) Considered  the  pro  forma  effect of  the  Mergers  on  the  Company's
       capitalization ratios and earnings, dividends and book value per share;
 
    (9) Reviewed the Agreement; and
 
    (10) Reviewed such other financial studies and performed such other analyses
       and took into account such other matters as we deemed necessary.
 
    In preparing our opinion, we have relied on the accuracy and completeness of
all  information supplied or otherwise  made available to us  by the Company and
the Merger Partner, and we have  not independently verified such information  or
undertaken  an independent appraisal of the assets or liabilities, contingent or
otherwise, of the Company or the  Merger Partner. With respect to the  financial
forecasts  furnished by the Company and the Merger Partner, we have assumed that
they have been reasonably prepared in accordance with accepted industry practice
and reflect the best currently available estimates and judgment of the Company's
and the  Merger  Partner's  management  as  to  the  expected  future  financial
performance  of the Company or the Merger Partner, as the case may be, and as to
the expected future projected  outcomes of various  legal, regulatory and  other
contingencies. We have also assumed that the Mergers will be free of Federal tax
to the Company, the Merger Partner and Sub and the respective holders of Company
Shares and Merger Partner Shares, and we further assume that the Mergers will be
accounted  for as  a pooling  of interests.  Our opinion  is based  upon general
economic, market,  monetary  and other  conditions  as  they exist  and  can  be
evaluated, and the information made available to us, as of the date hereof.
 
    We  have, in the past, provided financial advisory and financing services to
the Company  and have  received fees  for  the rendering  of such  services.  In
addition,  in the  ordinary course of  our securities business,  we may actively
trade debt and equity securities of the  Company and the Merger Partner for  our
own account and the accounts of our customers, and we therefore may from time to
time hold a long or short position in such securities.
 
   
    Management  of  the  Company  has  advised us  that  it  believes  there are
significant contingencies  and uncertainties  associated  with the  proposal  of
Western  Resources, Inc.  ("WR") to  acquire the  outstanding Company  Shares by
means of  an  exchange  offer and  merger  (as  set forth  in  the  Registration
Statement  on Form  S-4 (the  "Form S-4")  filed by  WR with  the Securities and
Exchange Commission on April 22, 1996, as amended by the terms contained in WR's
press release issued on June  17, 1996 and contained in  Amendment No. 1 to  the
Form S-4 filed with the Securities and Exchange Commission on June 19, 1996 (the
"WR Proposal")), due to the speculative nature of certain assumptions made by WR
in  the  WR Proposal  relating to  WR's  ability to  achieve and  retain certain
estimated aggregate cost  savings, and the  likelihood of substantially  greater
rate  reductions affecting WR in a pending rate proceeding than those assumed by
WR. Management of the Company has also  advised us that it believes that the  WR
Proposal is not consistent with the strategic objectives of the Company. In view
of  the foregoing,  we have  not been  asked by  the Board  of Directors  of the
Company to consider, and we have not considered, the WR Proposal in arriving  at
our opinion.
    
 
    On  the basis of,  and subject to  the foregoing and  other matters which we
deem relevant, we are of the opinion  that, as of the date hereof, the  proposed
Exchange  Ratio pursuant to the Mergers is fair to the holders of Company Shares
(other than the  Merger Partner and  its affiliates) from  a financial point  of
view.
 
                                        Very truly yours,

Board of Directors
UtiliCorp United Inc.
911 Main Street
Kansas City, Missouri 64105
 
Dear Sirs:
 
    You  have requested our opinion as to the fairness from a financial point of
view to  the  shareholders of  UtiliCorp  United  Inc. (the  "Company")  of  the
exchange  ratio applicable to  the determination of  the number of  shares to be
received by such shareholders pursuant to the terms of the Agreement and Plan of
Merger dated as of  January 19, 1996  as amended and restated  on May 20,  1996,
among  the Company, Kansas City  Power & Light Company  ("KCPL"), KC Merger Sub,
Inc. ("Sub") and KC  United Corp., ("KCU"), (the  "Agreement"). Pursuant to  the
Merger  Agreement,  Sub will  merge  with and  into  the Company  (the surviving
entity) and immediately thereafter, the Company  will merge with and into  KCPL,
with  KCPL  being  the  surviving  entity.  It  is  our  understanding  that the
transactions described in the Agreement (the "Mergers") are intended to  qualify
for  pooling  of interests  treatment for  financial  reporting purposes  and as
tax-free reorganizations for United States income tax purposes and that none  of
the  Company, KCPL, Sub or KCU will recognize any gain or loss for United States
income tax  purposes as  a result  of the  Mergers. We  further understand  that
consummation  of the Mergers is subject to the terms and conditions set forth in
the Agreement.
 
    Pursuant to the Agreement, each share of common stock of the Company will be
converted into the right to receive 1.000  shares of common stock, no par  value
of KCPL.
 
    In  arriving  at our  opinion, we  have  reviewed the  Agreement as  well as
financial and other information that was  publicly available or furnished to  us
by  the Company and KCPL including  information provided during discussions with
their  respective  managements  concerning   their  respective  businesses   and
prospects.  Included  in the  information provided  during discussions  with the
respective managements were  certain financial  projections of  the Company  for
calendar  years begining with 1995 and ending in 2000 prepared by the management
of the Company and certain fiinancial projections of KCPL for the calendar years
beginning with 1995 and ending  in 2000 prepared by  the management of KCPL.  We
analyzed  the respective  contributions in terms  of assets,  earnings, and cash
flow of each of the Company and  KCPL to the combined company and also  analyzed
the  valuation of  each company's  shares using  various valuation methodologies
which we deemed appropriate. In addition, we have compared certain financial and
securities data  of  the Company  and  KCPL  with various  other  companies  who
securities  are traded in  public markets, reviewed  the historical stock prices
and trading  volumes of  the  common stock  of each  of  the Company  and  KCPL,
reviewed  prices and premiums paid in  other business combinations and conducted
such  other  financial  studies,  analyses  and  investigations  as  we   deemed
appropriate  for purposes of this opinion. We were not requested to, nor did we,
solicit the interest of any other party in acquiring the Company.
 
    In rendering our  opinion, we  have relied  upon and  assumed the  accuracy,
completeness and fairness of all of the financial and other information that was
available  to us from  public sources, that  was provided to  us by the Company,
KCPL or their respective representatives, or that was otherwise reviewed by  us.
In  particular,  we have  relied upon  the  estimates of  the management  of the
Company of the  operating synergies  that can  be achieved  as a  result of  the
Mergers  and retained upon our discussion  of such synergies with the management
of KCPL.  With respect  to the  financial projections  supplied to  us, we  have
assumed that they have been reasonably prepared on the basis reflecting the best
currently  available estimates and judgments of  the mangement of the Company as
to the future operating  and financial performance of  the Company and KCPL.  We
have  not assumed any responsibility for making an independent evaluation of the
Company's or  KCPL's  assets  or  liabilities  or  for  making  any  independent
verification  of any of the information reviewed by us. We have relied as to all
legal matters relating  to the  Mergers, including without  limitation, the  tax
treatment of the Mergers, on advice of counsel to the Company.
 
                                      C-1

    Our  opinion is necessarily  based on economic,  market, financial and other
conditions as they exist on, and on the information made available to us as  of,
the  date  of this  letter. It  should be  understood that,  although subsequent
developments may affect this opinion, we  do not have any obligation to  update,
revise  or reaffirm this opinion. We are  expressing no opinion herein as to the
prices at which  shares of KCPL  will trade  either prior to,  or following  the
Mergers. Our opinion does not constitute a recommendation to any shareholders as
to how such shareholder should vote on the proposed transaction.
 
    Donaldson,  Lufkin & Jenrette Securities Corporation ("DLJ"), as part of its
investment banking services, is regularly engaged in the valuation of businesses
and securities in  connection with mergers,  acquisitions, underwritings,  sales
and  distributions  of listed  and unlisted  securities, private  placements and
valuations  for  estate,  corporate  and  other  purposes.  DLJ  has   performed
investment  banking and other services for the  Company and KCPL in the past and
has been compensated for such services.
 
    Based upon the foregoing  and such other factors  as we deemed relevant,  we
are  of the opinion that  the exchange ratio applicable  to the determination of
the number of shares to be received by the shareholders of the Company  pursuant
to  the Agreement is  fair to the  shareholders of the  Company from a financial
point of view.
 
                                                 Very truly yours,

Company  and its  Affiliates. Among other  things, the Committee  shall have the
authority, subject to the terms of the Plan:

    The Committee  shall have  the authority  to adopt,  alter and  repeal  such
administrative  rules, guidelines and  practices governing the  Plan as it shall
from time to time deem advisable, to  interpret the terms and provisions of  the
Plan  and any Award issued  under the Plan (and  any agreement relating thereto)

except that the members hereof may (i) delegate to an officer of the Company the
authority to make decisions pursuant to paragraphs (c), (f), (g), (h) and (i) of

the Exchange Act)  and (ii) authorize  any one or  more of their  number or  any
officer  of  the Company  to  execute and  deliver  documents on  behalf  of the

    Section 3.   COMMON STOCK  SUBJECT TO PLAN;  OTHER LIMITATIONS.   The  total
number  of shares of Common Stock reserved  and available for issuance under the
Plan shall be 9,000,000; PROVIDED, HOWEVER, that not more than 3,000,000 of such
shares shall be issued as Restricted Stock. No participant may be granted Awards
covering in excess of 600,000 shares of  Common Stock in any one calendar  year.
Shares  subject to an Award under the Plan may be authorized and unissued shares
or may be treasury  shares. No participant may  be granted Performance Units  in
any one calendar year payable in cash in an amount that would exceed $2,000,000.
 
    Subject  to  Section  7(c)(iv),  if  any  shares  of  Restricted  Stock  are
forfeited, or if any Stock Option (and related Stock Appreciation Right, if any)
terminates without  being  exercised, or  if  any Stock  Appreciation  Right  is
exercised  for cash, shares subject to such  Awards shall again be available for
distribution in connection with Awards under the Plan.
 
    In the event  of any  change in corporate  capitalization, such  as a  stock
split,   or  a  corporate  transaction,   such  as  any  merger,  consolidation,
separation, including a spin-off, or other distribution of stock or property  of
the Company, any reorganization (whether or not such reorganization comes within
the  definition of  such term  in Section  368 of  the Code)  or any  partial or
complete liquidation  of the  Company,  the Committee  or  Board may  make  such
substitution  or adjustments in the aggregate number and kind of shares reserved
for issuance under  the Plan, in  the number,  kind and option  price of  shares
subject  to  outstanding Stock  Options and  Stock  Appreciation Rights,  in the
number and kind of shares subject to other outstanding Awards granted under  the
Plan and/or such other equitable substitution or adjustments as it may determine
to  be appropriate in its sole discretion; PROVIDED, HOWEVER, that the number of
shares subject to any Award shall always be a whole number. Such adjusted option
price shall also be used to determine the amount payable by the Company upon the
exercise of any Stock Appreciation Right associated with any Stock Option.
 
    Section 4.   ELIGIBILITY.   Officers and employees  of the  Company and  its
Affiliates  who are responsible for or  contribute to the management, growth and
profitability of the business of the Company and its Affiliates are eligible  to
be  granted Awards under the Plan.  No grant shall be made  under this Plan to a
director who is not an officer or a salaried employee.
 
    Section 5.   STOCK  OPTIONS.   Stock  Options may  be  granted alone  or  in
addition  to  other Awards  granted  under the  Plan and  may  be of  two types:
Incentive Stock Options and Nonqualified Stock Options. Any Stock Option granted
under the Plan  shall be in  such form as  the Committee may  from time to  time
approve.
 
    The Committee shall have the authority to grant any optionee Incentive Stock
Options, Nonqualified Stock Options or both types of Stock Options (in each case
with  or  without Stock  Appreciation  Rights); PROVIDED,  HOWEVER,  that grants
hereunder  are  subject  to  the   aggregate  limit  on  grants  to   individual
participants set forth in Section 3. Incentive Stock Options may be granted only
to  employees of the Company and its subsidiaries (within the meaning of Section
424(f) of the Code). To the extent that any Stock Option is not designated as an
Incentive Stock Option or even if so designated does not qualify as an Incentive
Stock Option, it shall constitute a Nonqualified Stock Option.
 
    Stock Options  shall  be  evidenced  by option  agreements,  the  terms  and
provisions  of which may differ. An option  agreement shall indicate on its face
whether it is intended  to be an  agreement for an Incentive  Stock Option or  a
Nonqualified  Stock Option. The grant of a  Stock Option shall occur on the date
the Committee by  resolution selects an  individual to be  a participant in  any
grant  of a Stock Option, determines the number  of shares of Common Stock to be
subject to such Stock Option to be granted to such individual and specifies  the
terms and provisions of the Stock Option. The Company shall notify a participant
of  any grant of  a Stock Option,  and a written  option agreement or agreements
shall be duly  executed and delivered  by the Company  to the participant.  Such
agreement or agreements shall become effective upon execution by the Company and
the participant.

    Anything  in the Plan to  the contrary notwithstanding, no  term of the Plan
relating to Incentive Stock Options shall be interpreted, amended or altered nor
shall any discretion or authority granted under  the Plan be exercised so as  to
disqualify the Plan under Section 422 of the Code or, without the consent of the
optionee  affected, to disqualify any Incentive  Stock Option under such Section
422.
 
    Stock Options granted under the Plan shall be subject to the following terms
and conditions and  shall contain such  additional terms and  conditions as  the
Committee shall deem desirable:
 
        (a)    OPTION  PRICE.    The option  price  per  share  of  Common Stock
    purchasable under a Stock  Option shall be determined  by the Committee  and
    set forth in the option agreement.
 
        (b)   OPTION TERM.  The term of  each Stock Option shall be fixed by the
    Committee, but no Incentive Stock Option  shall be exercisable more than  10
    years after the date the Stock Option is granted.
 
        (c)  EXERCISABILITY.  Except as otherwise provided herein, Stock Options
    shall  be exercisable at  such time or  times and subject  to such terms and
    conditions as  shall  be  determined  by the  Committee.  If  the  Committee
    provides  that any  Stock Option  is exercisable  only in  installments, the
    Committee may at  any time  waive such installment  exercise provisions,  in
    whole  or in part, based on such  factors as the Committee may determine. In
    addition, the Committee may at any time accelerate the exercisability of any
    Stock Option.
 
        (d)  METHOD OF EXERCISE.  Subject  to the provisions of this Section  5,
    Stock  Options may be exercised, in whole or in part, at any time during the
    option term by giving written notice  of exercise to the Company  specifying
    the  number of  shares of  Common Stock  subject to  the Stock  Option to be
    purchased.
 
    Such notice shall be accompanied by payment in full of the purchase price by
certified or bank check or such other  instrument as the Company may accept.  If
approved  by the Committee, payment in  full or in part may  also be made in the
form of unrestricted  Common Stock  already owned by  the optionee  of the  same
class  as the Common Stock subject  to the Stock Option and,  in the case of the
exercise of a Nonqualified  Stock Option, Restricted Stock  subject to an  Award
hereunder  which is of the  same class as the Common  Stock subject to the Stock
Option (based, in each case, on the Fair Market Value of the Common Stock on the
date the Stock Option is exercised); PROVIDED, HOWEVER, that, in the case of  an
Incentive Stock Option, the right to make a payment in the form of already owned
shares  of Common  Stock of the  same class as  the Common Stock  subject to the
Stock Option may be authorized only at the time the Stock Option is granted.
 
    If payment of the  option exercise price of  a Nonqualified Stock Option  is
made  in whole or in part in the  form of Restricted Stock, the number of shares
of Common Stock to be received upon such exercise equal to the number of  shares
of  Restricted Stock  used for  payment of  the option  exercise price  shall be
subject to the same forfeiture restrictions  to which such Restricted Stock  was
subject, unless otherwise determined by the Committee.
 
    In  the discretion  of the  Committee, payment for  any shares  subject to a
Stock Option may also be made by delivering a properly executed exercise  notice
to  the Company, together with a copy of irrevocable instructions to a broker to
deliver promptly to the Company the amount  of sale or loan proceeds to pay  the
purchase  price, and, if  requested by the  Company, the amount  of any federal,
state, local  or foreign  withholding taxes.  To facilitate  the foregoing,  the
Company  may enter into  agreements for coordinated procedures  with one or more
brokerage firms.
 
    No shares of Common  Stock shall be issued  until full payment therefor  has
been  made. Subject  to any  forfeiture restrictions that  may apply  if a Stock
Option is exercised using  Restricted Stock, an Optionee  shall have all of  the
rights  of a shareholder  of the Company  holding the class  or series of Common
Stock that is subject to such Stock Option (including, if applicable, the  right
to  vote the shares and  the right to receive  dividends), when the optionee has
given written notice  of exercise,  has paid  in full  for such  shares and,  if
requested, has given the representation described in Section 13(a).
 
                                      D-5
<PAGE>
        (e)   NONTRANSFERABILITY  OF STOCK  OPTIONS.   No Stock  Option shall be
    transferable by  the optionee  other than  (i) by  will or  by the  laws  of
    descent and distribution or (ii) in the case of a Nonqualified Stock Option,
    pursuant  to  a  gift  to  such  optionee's  children,  whether  directly or
    indirectly or by means of a trust or partnership or otherwise, if  expressly
    permitted  under the applicable option agreement. All Stock Options shall be
    exercisable, during the optionee's lifetime, only by the optionee or by  the
    guardian  or legal representative of the  optionee, it being understood that
    the  terms  "holder"   and  "optionee"  include   the  guardian  and   legal
    representative  of the optionee named in the option agreement and any person
    to whom  an  option is  transferred  by will  or  the laws  of  descent  and
    distribution  or,  in  the  case  of a  Nonqualified  Stock  Option,  a gift
    permitted under the applicable option agreement.
 
        (f)    TERMINATION  BY  DEATH.    Unless  otherwise  determined  by  the
    Committee,  if an optionee's  employment terminates by  reason of death, any
    Stock Option  held by  such optionee  may thereafter  be exercised,  to  the
    extent  then exercisable, or on such  accelerated basis as the Committee may
    determine, for a period of one year  (or such other period as the  Committee
    may  specify in the option  agreement) from the date  of such death or until
    the expiration of the stated term of such Stock Option, whichever period  is
    the shorter.
 
        (g)   TERMINATION BY REASON OF  DISABILITY.  Unless otherwise determined
    by the  Committee,  if an  optionee's  employment terminates  by  reason  of
    Disability,  any  Stock  Option  held by  such  optionee  may  thereafter be
    exercised by the optionee, to the extent  it was exercisable at the time  of
    termination,  or on such  accelerated basis as  the Committee may determine,
    for a period of  three years (or  such shorter period  as the Committee  may
    specify  in  the option  agreement)  from the  date  of such  termination of
    employment or until the expiration of the stated term of such Stock  Option,
    whichever  period is  the shorter; PROVIDED,  HOWEVER, that  if the optionee
    dies within such three-year period (or such shorter period), any unexercised
    Stock Option held by such optionee shall, notwithstanding the expiration  of
    such  three-year (or such shorter) period, continue to be exercisable to the
    extent to which it was exercisable at the  time of death for a period of  12
    months  from the date  of such death  or until the  expiration of the stated
    term of such Stock Option, whichever period is the shorter. In the event  of
    termination  of employment  by reason of  Disability, if  an Incentive Stock
    Option is exercised after the expiration of the exercise periods that  apply
    for  purposes of Section 422 of the  Code, such Stock Option will thereafter
    be treated as a Nonqualified Stock Option.
 
        (h)  TERMINATION BY REASON  OF RETIREMENT.  Unless otherwise  determined
    by  the  Committee,  if an  optionee's  employment terminates  by  reason of
    Retirement, any  Stock  Option  held  by such  optionee  may  thereafter  be
    exercised  by the optionee, to the extent  it was exercisable at the time of
    such  Retirement,  or  on  such  accelerated  basis  as  the  Committee  may
    determine,  for  a period  of three  years  (or such  shorter period  as the
    Committee may  specify  in the  option  agreement)  from the  date  of  such
    termination of employment or until the expiration of the stated term of such
    Stock  Option, whichever period  is the shorter;  PROVIDED, HOWEVER, that if
    the optionee  dies  within such  three-year  (or such  shorter)  period  any
    unexercised  Stock Option held  by such optionee  shall, notwithstanding the
    expiration of  such three-year  (or  such shorter)  period, continue  to  be
    exercisable  to the extent to which it  was exercisable at the time of death
    for a  period  of 12  months  from  the date  of  such death  or  until  the
    expiration  of the stated term of such Stock Option, whichever period is the
    shorter. In the event of termination of employment by reason of  Retirement,
    if  an  Incentive Stock  Option  is exercised  after  the expiration  of the
    exercise periods that apply  for purposes of Section  422 of the Code,  such
    Stock Option will thereafter be treated as a Nonqualified Stock Option.
 
        (i)   OTHER TERMINATION.  Unless  otherwise determined by the Committee,
    if an optionee incurs a Termination of Employment for any reason other  than
    death,  Disability or  Retirement, any  Stock Option  held by  such optionee
    shall thereupon terminate, except that such Stock Option, to the extent then
    exercisable, or on such  accelerated basis as  the Committee may  determine,
    may  be  exercised for  the lesser  of three  months from  the date  of such
    Termination of
 
                                      D-6
<PAGE>
    Employment or  the  balance of  such  Stock  Option's stated  term  if  such
    Termination of Employment of the optionee is involuntary; PROVIDED, HOWEVER,
    that  if the optionee  dies within such  three-month period, any unexercised
    Stock Option held by such optionee shall, notwithstanding the expiration  of
    such  three-month period, continue to be  exercisable to the extent to which
    it was exercisable at the time of death  for a period of 12 months from  the
    date  of such death or until the expiration of the stated term of such Stock
    Option, whichever period is the  shorter. Notwithstanding the foregoing,  if
    an  optionee incurs  a Termination  of Employment  at or  after a  Change in
    Control (as  defined  in Section  9(b)),  other  than by  reason  of  death,
    Disability  or Retirement, any  Stock Option held by  such optionee shall be
    exercisable for the lesser of  (1) six months and one  day from the date  of
    such  Termination of Employment, and (2)  the balance of such Stock Option's
    stated term. In  the event  of Termination  of Employment,  if an  Incentive
    Stock  Option is exercised after the expiration of the exercise periods that
    apply for  purposes of  Section 422  of  the Code,  such Stock  Option  will
    thereafter be treated as a Nonqualified Stock Option.
 
        (j)   CASHING  OUT OF  STOCK OPTION.   On  receipt of  written notice of
    exercise, the Committee may elect to cash out all or part of the portion  of
    the  shares of Common Stock  for which a Stock  Option is being exercised by
    paying the optionee an amount, in cash or Common Stock, equal to the  excess
    of the Fair Market Value of the Common Stock over the option price times the
    number  of shares of Common Stock for which the Option is being exercised on
    the effective date of such cash-out.
 
         Cash-outs pursuant  to this Section  5(j) relating to  Options held  by
    optionees  who are Reporting  Persons shall comply  with the "window period"
    provisions of Rule  16b-3, to  the extent applicable,  and, in  the case  of
    cash-outs  of  Nonqualified  Stock  Options  held  by  such  optionees,  the
    Committee may determine Fair Market Value  under the pricing rule set  forth
    in Section 6(b)(ii)(2).
 
        (k)  CHANGE IN CONTROL CASH-OUT.  Notwithstanding any other provision of
    the  Plan, during the 60-day period from  and after a Change in Control (the
    "Exercise Period"), unless  the Committee shall  determine otherwise at  the
    time  of grant, an optionee  shall have the right,  whether or not the Stock
    Option is fully exercisable and in lieu of the payment of the exercise price
    for the shares of Common Stock being purchased under the Stock Option and by
    giving notice  to the  Company, to  elect (within  the Exercise  Period)  to
    surrender  all or  part of the  Stock Option  to the Company  and to receive
    cash, within 30 days  of such notice,  in an amount equal  to the amount  by
    which  the Change in Control Price per share  of Common Stock on the date of
    such election shall  exceed the  exercise price  per share  of Common  Stock
    under  the Stock Option (the "Spread") multiplied by the number of shares of
    Common Stock granted under  the Stock Option as  to which the right  granted
    under  this Section 5(k) shall have  been exercised; PROVIDED, HOWEVER, that
    if the Change  in Control is  within six months  of the date  of grant of  a
    particular  Stock Option held by  an optionee who is  a Reporting Person, no
    such election shall  be made  by such optionee  with respect  to such  Stock
    Option  prior to six months  from the date of grant.  However, if the end of
    such 60-day period from and after a  Change in Control is within six  months
    of  the  date of  grant of  a  Stock Option  held by  an  optionee who  is a
    Reporting Person, such  Stock Option shall  be cancelled in  exchange for  a
    cash  payment to the optionee,  effected on the day  which is six months and
    one day  after  the date  of  grant of  such  Option, equal  to  the  Spread
    multiplied  by the number of shares of  Common Stock granted under the Stock
    Option.
 
    Section 6.  STOCK APPRECIATION RIGHTS.
 
    (a)   GRANT AND  EXERCISE.   Stock  Appreciation Rights  may be  granted  in
conjunction  with all or part of any Stock Option granted under the Plan. In the
case of a Nonqualified  Stock Option, such  rights may be  granted either at  or
after  the time of grant of such Stock Option. In the case of an Incentive Stock
Option, such rights  may be  granted only  at the time  of grant  of such  Stock
Option.  A Stock Appreciation Right shall terminate and no longer be exercisable
upon the termination or exercise of the related Stock Option.
 
                                      D-7
<PAGE>
    A Stock Appreciation  Right may be  exercised by an  optionee in  accordance
with  Section 6(b) by  surrendering the applicable portion  of the related Stock
Option in accordance  with procedures  established by the  Committee. Upon  such
exercise  and surrender, the optionee shall be  entitled to receive an amount in
the manner  prescribed  in  Section  6(b). Stock  Options  which  have  been  so
surrendered  shall  no longer  be exercisable  to the  extent the  related Stock
Appreciation Rights have been exercised.
 
    (b)  TERMS AND  CONDITIONS.  Stock Appreciation  Rights shall be subject  to
such terms and conditions as shall be determined by the Committee, including the
following:
 
        (i)  Stock Appreciation Rights shall be exercisable only at such time or
    times and to  the extent that  the Stock  Options to which  they relate  are
    exercisable  in accordance with the provisions of Section 5 and this Section
    6;  PROVIDED,  HOWEVER,  that  a  Stock  Appreciation  Right  shall  not  be
    exercisable  during the first six months of its term by an optionee who is a
    Reporting Person, except that this limitation  shall not apply in the  event
    of  death  or Disability  of the  optionee  prior to  the expiration  of the
    six-month period.
 
        (ii) Upon the exercise of a Stock Appreciation Right, an optionee  shall
    be  entitled to receive  an amount in  cash, shares of  Common Stock or both
    equal in value to the excess of the Fair Market Value of one share of Common
    Stock over the option price per share specified in the related Stock  Option
    multiplied   by  the  number  of  shares  in  respect  of  which  the  Stock
    Appreciation Right shall have been exercised, with the Committee having  the
    right to determine the form of payment.
 
         In the case of Stock Appreciation Rights relating to Stock Options held
    by optionees who are Reporting Persons, the Committee:
 
           (1) may require that such Stock Appreciation Rights be exercised  for
       cash only in accordance with the applicable "window period" provisions of
       Rule 16b-3; and
 
           (2) in the case of Stock Appreciation Rights relating to Nonqualified
       Stock  Options,  may provide  that the  amount  to be  paid in  cash upon
       exercise of such Stock  Appreciation Rights during  a Rule 16b-3  "window
       period"  shall be  based on  the highest of  the daily  means between the
       highest and lowest reported sales prices  of the Common Stock on the  New
       York  Stock Exchange or  other national securities  exchange on which the
       shares are listed  or on NASDAQ,  as applicable, on  any day during  such
       "window period."
 
       (iii)  Stock Appreciation Rights shall  be transferable only to permitted
    transferees of the underlying Stock Option in accordance with Section 5(e).
 
       (iv) Upon the exercise of a Stock Appreciation Right, the Stock Option or
    part thereof to  which such  Stock Appreciation  Right is  related shall  be
    deemed to have been exercised for the purpose of the limitation set forth in
    Section  3 on the  number of shares of  Common Stock to  be issued under the
    Plan, but only to the extent of the  number of shares as to which the  Stock
    Appreciation Right is exercised at the time of exercise.
 
    Section 7.  RESTRICTED STOCK.
 
    (a)  ADMINISTRATION.  Shares of Restricted Stock may be awarded either alone
or  in addition  to other  Awards granted  under the  Plan. The  Committee shall
determine the officers  and employees to  whom and  the time or  times at  which
grants  of Restricted Stock will be awarded,  the number of shares to be awarded
to any  participant (subject  to the  aggregate limit  on grants  to  individual
participants  set forth in Section  3), the conditions for  vesting, the time or
times within which such Awards may be subject to forfeiture and any other  terms
and conditions of the Awards, in addition to those contained in 7(c).
 
    Subject  to the immediately succeeding sentence,  the Committee shall in the
case of Covered Employees, and may in the case of other Participants,  condition
the grant or vesting of Restricted
 
                                      D-8
<PAGE>
Stock upon the attainment of Performance Goals established before or at the time
of grant. Notwithstanding the foregoing, the Committee shall have the discretion
to  grant to an employee who has become entitled to an award under the Company's
Management Incentive Compensation Plan,  in payment of all  or any part of  such
award,  shares  of  Restricted  Stock  that shall  vest  without  regard  to the
attainment of Performance  Goals. The  Committee may, in  addition to  requiring
satisfaction  of any applicable  Performance Goals, also  condition vesting upon
the continued service  of the  participant. The provisions  of Restricted  Stock
Awards  (including the applicable  Performance Goals) need not  be the same with
respect to each recipient.
 
    (b)  AWARDS AND CERTIFICATES.  Shares of Restricted Stock shall be evidenced
in such  manner as  the  Committee may  deem appropriate,  including  book-entry
registration  or issuance  of one  or more  stock certificates.  Any certificate
issued in respect of shares of Restricted Stock shall be registered in the  name
of such participant and shall bear an appropriate legend referring to the terms,
conditions,  and  restrictions applicable  to such  Award, substantially  in the
following form:
 
          "The  transferability of  this certificate  and  the shares  of  stock
    represented  hereby  are  subject  to the  terms  and  conditions (including
    forfeiture) of  the  Maxim  Stock  Incentive Plan  and  a  Restricted  Stock
    Agreement.  Copies of such Plan and Agreement  are on file at the offices of
    Maxim at                                 ."
 
    The Committee may require  that the certificates  evidencing such shares  be
held  in custody by the Company until the restrictions thereof shall have lapsed
and that, as a condition of any Award of Restricted Stock, the participant shall
have delivered a stock  power, endorsed in blank,  relating to the Common  Stock
covered by such Award.
 
    (c)   TERMS AND CONDITIONS.  Shares  of Restricted Stock shall be subject to
the following terms and conditions:
 
        (i) Subject to the provisions of  the Plan (including Section 5(d))  and
    the  Restricted Stock Agreement referred to  in Section 7(c)(vi), during the
    period, if any, set by the Committee, commencing with the date of such Award
    for which such participant's continued service is required (the "Restriction
    Period"), and  until the  later of  (i) the  expiration of  the  Restriction
    Period  and  (ii) the  date the  applicable Performance  Goals (if  any) are
    satisfied, the participant shall not be permitted to sell, assign, transfer,
    pledge or  otherwise  encumber  shares of  Restricted  Stock.  Within  these
    limits,  the Committee may provide for  the lapse of restrictions based upon
    period of service in installments or otherwise and may accelerate or  waive,
    in  whole or  in part,  restrictions based  upon period  of service  or upon
    performance; PROVIDED, HOWEVER, that  in the case  of Restricted Stock  with
    respect  to  which  a  participant is  a  Covered  Employee,  any applicable
    Performance Goals have been satisfied.
 
        (ii) Except as provided in this  paragraph (ii) and Section 7(c)(i)  and
    the  Restricted Stock Agreement, the participant shall have, with respect to
    the shares of Restricted Stock,  all of the rights  of a shareholder of  the
    Company  holding the class or series of  Common Stock that is the subject of
    the Restricted Stock, including, if applicable, the right to vote the shares
    and the  right  to receive  any  cash dividends.  If  so determined  by  the
    Committee  in  the  applicable  Restricted Stock  Agreement  and  subject to
    Section 13(f) of  the Plan, (1)  cash dividends  on the class  or series  of
    Common  Stock that  is the  subject of the  Restricted Stock  Award shall be
    automatically deferred and reinvested  in additional Restricted Stock,  held
    subject  to the vesting of the  underlying Restricted Stock, or held subject
    to meeting Performance Goals applicable only to dividends, and (2) dividends
    payable in Common Stock shall be paid in the form of Restricted Stock of the
    same class  as the  Common Stock  with which  such dividend  was paid,  held
    subject  to the vesting of the  underlying Restricted Stock, or held subject
    to meeting Performance Goals applicable only to dividends.
 
                                      D-9
<PAGE>
       (iii)  Except  to  the  extent  otherwise  provided  in  the   applicable
    Restricted  Stock Agreement, any applicable employment agreement and Section
    7(c)(i),  7(c)(iv)  and  9(a)(ii),  upon  a  participant's  Termination   of
    Employment  for  any  reason during  the  Restriction Period  or  before the
    applicable Performance  Goals are  satisfied, all  shares still  subject  to
    restriction shall be forfeited by the participant.
 
       (iv)  Except to the extent otherwise provided in Section 9(a)(ii), in the
    event that  a  participant  retires  or  such  participant's  employment  is
    involuntarily  terminated, the Committee shall  have the discretion to waive
    in whole or in part  any or all remaining  restrictions (other than, in  the
    case  of Restricted Stock with  respect to which a  participant is a Covered
    Employee, satisfaction of  the applicable  Performance Goals  to the  extent
    necessary  for the shares to be deductible by the Company or its Affiliates,
    unless the  participant's employment  is terminated  by reason  of death  or
    Disability)  with  respect to  any or  all of  such participant's  shares of
    Restricted Stock.
 
        (v) If and when the applicable  Performance Goals are satisfied and  the
    Restriction  Period  expires without  a prior  forfeiture of  the Restricted
    Stock, unlegended  certificates of  such shares  shall be  delivered to  the
    participant upon surrender of the legended certificates.
 
       (vi)  Each Award shall be confirmed by, and be subject to the terms of, a
    Restricted Stock Agreement.
 
    Section 8.  PERFORMANCE UNITS
 
    (a)  ADMINISTRATION.   Performance Units may be  awarded either alone or  in
addition  to  other Awards  granted  under the  Plan.  Performance Units  may be
denominated in shares of  Common Stock or  cash, or may  represent the right  to
receive  dividend equivalents  with respect  to shares  of Common  Stock, as the
Committee shall  determine.  The  Committee shall  determine  the  officers  and
employees  to whom  and the time  or times  at which Performance  Units shall be
awarded, the  form  and  number  of  Performance Units  to  be  awarded  to  any
participant (subject to the aggregate limit on grants to individual participants
set forth in Section 3), the duration of the Award Cycle and any other terms and
conditions of the Award, in addition to those contained in Section 8(b).
 
    The  Committee shall condition the settlement  of Performance Units upon the
attainment of Performance Goals.  The provisions of  such Awards (including  the
applicable  Performance  Goals)  need  not  be the  same  with  respect  to each
recipient.
 
    (b)  TERMS AND CONDITIONS.  Performance Units Awards shall be subject to the
following terms and conditions:
 
        (i) Subject  to the  provisions of  the Plan  and the  Performance  Unit
    Agreement  referred to  in Section  8(b)(vi), Performance  Units may  not be
    sold, assigned,  transferred, pledged  or  otherwise encumbered  during  the
    Award  Cycle.  At the  expiration of  the Award  Cycle, the  Committee shall
    evaluate actual performance in light of the Performance Goals for such Award
    and  shall  determine  the  number  of  Performance  Units  granted  to  the
    participant  which  have been  earned and  the Committee  may then  elect to
    deliver  cash,  shares  of  Common  Stock,  or  a  combination  thereof,  in
    settlement  of the  earned Performance Units,  in accordance  with the terms
    thereof.
 
        (ii)  Except  to  the  extent  otherwise  provided  in  the   applicable
    Performance  Unit  Agreement and  Sections 8(b)(iii)  and 9(a)(iii),  upon a
    participant's Termination  of Employment  for any  reason during  the  Award
    Cycle  or before the applicable Performance  Goals are satisfied, the rights
    to the  shares  still  covered  by the  Performance  Units  Award  shall  be
    forfeited by the participant.
 
       (iii)  Except to the  extent otherwise provided  in Section 9(a)(iii), in
    the event that a participant's  employment is involuntarily terminated,  the
    Committee shall have the discretion to waive
 
                                      D-10
<PAGE>
    in whole or in part any or all remaining payment limitations (other than, in
    the  case of  Performance Units  with respect  to which  a participant  is a
    Covered Employee, satisfaction  of the applicable  Performance Goals  unless
    the participant's employment is terminated by reason of death or Disability)
    with respect to any or all of such participant's Performance Units.
 
       (iv)  A participant may elect to further defer receipt of the Performance
    Units payable under an Award (or an installment of an Award) for a specified
    period or until a specified event,  subject in each case to the  Committee's
    approval and to such terms as are determined by the Committee (the "Elective
    Deferral  Period"). Subject to any exceptions adopted by the Committee, such
    election must generally be made prior to commencement of the Award Cycle for
    the Award (or for such installment of an Award).
 
        (v) If and when the applicable  Performance Goals are satisfied and  the
    Elective   Deferral  Period  expires  without  a  prior  forfeiture  of  the
    Performance Units, payment in accordance  with Section 8(b)(i) hereof  shall
    be made to the participant.
 
       (vi)  Each Award shall be confirmed by, and be subject to the terms of, a
    Performance Unit Agreement.
 
    Section 9.  CHANGE IN CONTROL PROVISIONS.
 
    (a)  EFFECT OF EVENT.   Notwithstanding any other  provision of the Plan  to
the contrary, in the event of a Change in Control:
 
        (i)  Any Stock Options  and Stock Appreciation  Rights outstanding as of
    the date of such Change in Control and not then exercisable and vested shall
    become fully exercisable and vested.
 
        (ii) The restrictions  applicable to any  Restricted Stock shall  lapse,
    and  such Restricted Stock shall become  free of all restrictions and become
    fully vested and transferable.
 
       (iii) All Performance Units shall be considered to be earned and  payable
    in  full  and  any  deferral  or  other  restriction  shall  lapse  and such
    Performance Units shall be settled in cash as promptly as is practicable.

    of Rule 13d-3 promulgated under Section 13 of the Exchange Act), directly or

    beneficially  owned by such Person any securities acquired directly from the
    Company or its affiliates other than  in connection with the acquisition  by
    the  Company or its  affiliates of a  business) representing 20%  or more of
    either the then  outstanding shares of  common stock of  the Company or  the
    combined voting power of the Company's then outstanding securities; or
 
        (ii)  the following  individuals cease  for any  reason to  constitute a

    director whose initial assumption of office is in connection with an  actual
    or  threatened  election contest,  including but  not  limited to  a consent
    solicitation, relating to the  election of directors  of the Company)  whose
    appointment  or  election by  the Board  or nomination  for election  by the
    Company's stockholders was approved by a  vote of at least two-thirds  (2/3)
    of  the directors then still in office who either were directors on the date
    hereof or  whose  appointment,  election  or  nomination  for  election  was
    previously so approved; or
 
       (iii)  there is consummated a merger  or consolidation of the Company (or
    any  direct  or  indirect  subsidiary   of  the  Company)  with  any   other
    corporation,  other than (i) a merger or consolidation which would result in
    the voting securities of the  Company outstanding immediately prior to  such
    merger  or  consolidation  continuing  to  represent  (either  by  remaining

    entity or any parent
 
                                      D-11
<PAGE>
    thereof),  in  combination  with  the  ownership  of  any  trustee  or other
    fiduciary holding securities under an employee benefit plan of the  Company,
    at  least 80% of the  combined voting power of  the voting securities of the
    Company  or  such  surviving  entity  or  any  parent  thereof   outstanding
    immediately  after  such  merger  or  consolidation,  or  (ii)  a  merger or
    consolidation effected to  implement a recapitalization  of the Company  (or
    similar  transaction) in which no Person is or becomes the beneficial owner,
    directly or indirectly, of securities of  the Company (not including in  the
    securities  beneficially  owned  by  such  Person  any  securities  acquired
    directly from the Company or its subsidiaries other than in connection  with
    the   acquisition  by  the  Company  or  its  subsidiaries  of  a  business)
    representing 20% or  more of either  the then outstanding  shares of  common
    stock  of the  Company or  the combined voting  power of  the Company's then
    outstanding securities; or
 
       (iv)  the  stockholders  of  the  Company  approve  a  plan  of  complete
    liquidation  or dissolution of the Company or there is consummated a sale or
    disposition by the  Company of  all or  substantially all  of the  Company's

    combined voting power of the voting securities of which are owned by Persons
    in  substantially the  same proportions  as their  ownership of  the Company
    immediately prior to such sale.
 
         For purposes  of the above  definition of Change  in Control,  "Person"
    shall  have the meaning set forth in Section 3(a)(9) of the Exchange Act, as
    modified and used in Sections 13(d) and 14(d) thereof, except that such term
    shall not include (i) the Company or any of its subsidiaries, (ii) a trustee

    substantially the  same  proportions as  their  ownership of  stock  of  the
    Company.
 
    (c)   CHANGE IN CONTROL PRICE.  For purposes of the Plan, "Change in Control
Price" means the higher of (i) the highest reported sales price, regular way, of
a share  of Common  Stock in  any transaction  reported on  the New  York  Stock
Exchange  Composite Tape  or other  national exchange  on which  such shares are
listed or on NASDAQ during the 60-day period prior to and including the date  of
a  Change in Control or (ii) if the Change  in Control is the result of a tender
or exchange offer  or a Corporate  Transaction, the highest  price per share  of
Common  Stock paid  in such tender  or exchange offer  or Corporate Transaction;
PROVIDED, HOWEVER, that (x) in the case of  a Stock Option which (A) is held  by
an  optionee who  is an  officer or director  of the  Company and  is subject to
Section 16(b) of the  Exchange Act and  (B) was granted within  180 days of  the
Change  in Control, then the Change in Control Price for such Stock Option shall
be the Fair Market Value  of the Common Stock on  the date such Stock Option  is
exercised or deemed exercised and (y) in the case of Incentive Stock Options and
Stock  Appreciation Rights  relating to Incentive  Stock Options,  the Change in
Control Price shall be in all cases the Fair Market Value of the Common Stock on
the date such Incentive Stock Option  or Stock Appreciation Right is  exercised.
To  the extent  that the  consideration paid  in any  such transaction described
above consists all or in part of securities or other noncash consideration,  the
value  of such securities or other  noncash consideration shall be determined in
the sole discretion of the Board.
 
    Section 10.    LOANS.   The  Company may  make  loans to  a  participant  in
connection  with Awards subject  to the following terms  and conditions and such
other terms and conditions not inconsistent with the Plan as the Committee shall
impose from time to time, including without limitation (i) the rate of interest,
if any, (ii) the extent  to which the participant  shall be required to  provide
collateral  for such  loan, and  (iii) whether  such loan  shall be  recourse or
nonrecourse.
 
    No loan made under the plan shall exceed the sum of (i) the aggregate  price
payable  with respect to the  Award in relation to which  the loan is made, plus
(ii) the amount  of the  reasonably estimated  combined amounts  of Federal  and
state income taxes payable by the participant.
 
    No  loan  shall have  an initial  term exceeding  ten (10)  years; PROVIDED,
HOWEVER, that the loans under the Plan  shall be renewable at the discretion  of
the Committee; and FURTHER PROVIDED, HOWEVER,
 
                                      D-12
<PAGE>
that  the indebtedness under each loan shall become due and payable, as the case
may be, on a date no later than (i) one year after Termination of Employment due
to death, Retirement or Disability, or (ii) the day of Termination of Employment
for any reason other than death, Retirement or Disability.
 
    Loans under the Plan may be  satisfied by the participant, as determined  by
the  Committee, in cash  or, with the consent  of the Committee,  in whole or in
part in the form of unrestricted  Common Stock already owned by the  participant
where such Common Stock shall be valued at Fair Market Value on the date of such
payment.
 
    When  a loan shall have been made, Common  Stock with a Fair Market Value on
the date  of such  loan equivalent  to the  amount of  the loan  (or such  other
security  as shall be required  by the Committee in  its sole discretion) may be
pledged by the participant to the Company as security for payment of the  unpaid
balance of the loan. Any portions of such Common Stock may, in the discretion of
the  Committee, be released  from time to time  as it deems not  to be needed as
security.
 
    The making of any loan is subject to satisfying all applicable laws, as well
as any  regulations  and  rules of  the  Federal  Reserve Board  and  any  other
governmental agency having jurisdiction.
 
    Section  11.  TERM, AMENDMENT  AND TERMINATION.  The  Plan will terminate 10
years after the effective date of the  Plan. Awards outstanding as of such  date
shall not be affected or impaired by the termination of the Plan.
 
    The  Board  may amend,  alter, or  discontinue the  Plan, but  no amendment,
alteration or discontinuation shall be made which would (i) impair the rights of
an optionee under a Stock Option or  a recipient of a Stock Appreciation  Right,
Restricted Stock Award or Performance Unit Award theretofore granted without the
optionee's  or recipient's consent,  except such an amendment  made to cause the
Plan to qualify for the exemption provided by Rule 16b-3, or (ii) disqualify the
Plan from the exemption provided by Rule 16b-3 or from the provisions of Section
162(m)(4)(c) of the Code. In addition,  no such amendment shall be made  without
the  approval  of the  Company's  shareholders to  the  extent such  approval is
required by law or agreement.
 
    The Committee  may  amend the  terms  of any  Stock  Option or  other  Award
theretofore granted, prospectively or retroactively, but no such amendment shall
impair  the rights  of any  holder without the  holder's consent  except such an
amendment made to cause the Plan or Award to qualify for the exemption  provided
by Rule 16b-3.
 
    Subject to the above provisions, the Board shall have authority to amend the
Plan  to take into account changes in law  and tax and accounting rules, as well
as other developments and to grant Awards which qualify for beneficial treatment
under such rules without shareholder approval.
 
    Section 12.  UNFUNDED  STATUS OF PLAN.   It is  presently intended that  the
Plan  constitute an "unfunded" plan for incentive and deferred compensation. The
Committee may authorize the creation of trusts or other arrangements to meet the
obligations created under  the Plan to  deliver Common Stock  or make  payments;
PROVIDED,   HOWEVER,  that,  unless  the  Committee  otherwise  determines,  the
existence of such trusts or other arrangements is consistent with the "unfunded"
status of the Plan.
 
    Section 13.  GENERAL PROVISIONS.
 
    (a) The Committee  may require  each person purchasing  or receiving  shares
pursuant  to an Award to represent to and agree with the Company in writing that
such person is acquiring the shares without a view to the distribution  thereof.
The  certificates for  such shares  may include  any legend  which the Committee
deems appropriate to reflect any restrictions on transfer.
 
                                      D-13
<PAGE>
    Notwithstanding any other provision of the Plan or agreements made  pursuant
thereto,  the Company shall not be required  to issue or deliver any certificate
or certificates for shares of Common  Stock under the Plan prior to  fulfillment
of all of the following conditions:
 
        (1) The listing or approval for listing upon notice of issuance, of such
    shares  on  the New  York  Stock Exchange,  Inc.,  or such  other securities
    exchange as may at the time be the principal market for the Common Stock;
 
        (2) Any  registration  or other  qualification  of such  shares  of  the
    Company  under any state or Federal law or regulation, or the maintaining in
    effect of any such registration  or other qualification which the  Committee
    shall, in its absolute discretion upon the advice of counsel, deem necessary
    or advisable; and
 
        (3)  The obtaining  of any other  consent, approval, or  permit from any
    state or  Federal governmental  agency  which the  Committee shall,  in  its
    absolute  discretion after receiving the advice  of counsel, determine to be
    necessary or advisable,
 
    (b) Nothing contained in the Plan shall prevent the Company or any Affiliate
from adopting other or additional compensation arrangements for its employees.
 
    (c) The adoption of the Plan shall not confer upon any employee any right to
continued employment nor shall  it interfere in  any way with  the right of  the
Company  or any  Affiliate to  terminate the employment  of any  employee at any
time.
 
    (d) No later than the date as of which an amount first becomes includible in
the gross income of the participant for federal income tax purposes with respect
to any Award under the Plan, the  participant shall pay to the Company, or  make
arrangements  satisfactory to the Company regarding the payment of, any federal,
state, local or foreign taxes  of any kind required by  law to be withheld  with
respect  to such amount. Unless otherwise determined by the Company, withholding
obligations may be  settled with Common  Stock, including Common  Stock that  is
part  of  the  Award  that  gives  rise  to  the  withholding  requirement.  The
obligations of the Company under the  Plan shall be conditional on such  payment
or  arrangements,  and  the Company  and  its  Affiliates shall,  to  the extent
permitted by law,  have the  right to  deduct any  such taxes  from any  payment
otherwise due the participant. The Committee may establish such procedures as it
deems  appropriate,  including  the  making of  irrevocable  elections,  for the
settlement of withholding obligations with Common Stock.
 
    (e) At the time of grant, the  Committee may provide in connection with  any
grant  made under the Plan that the shares  of Common Stock received as a result
of such grant shall be subject to a right of first refusal pursuant to which the
participant shall  be required  to offer  to  the Company  any shares  that  the
participant  wishes to sell at  the then Fair Market  Value of the Common Stock,
subject to such other terms and conditions  as the Committee may specify at  the
time of grant.
 
    (f) The reinvestment of dividends in additional Restricted Stock at the time
of any dividend payment shall only be permissible if sufficient shares of Common
Stock  are available under Section 3  for such reinvestment (taking into account
then outstanding Stock Options and other Awards).
 
    (g) The Committee shall  establish such procedures  as it deems  appropriate
for  a participant to designate a beneficiary to whom any amounts payable in the
event of the participant's  death are to be  paid or by whom  any rights of  the
participant, after the participant's death, may be exercised.
 
    (h)  In the case of a grant of an Award to any employee of an Affiliate, the
Company may, if the Committee so directs, issue or transfer the shares of Common
Stock, if  any,  covered  by  the  Award  to  the  Affiliate,  for  such  lawful
consideration  as the Committee may specify, upon the condition or understanding
that the Affiliate will transfer the shares  of Common Stock to the employee  in
accordance  with the terms of  the Award specified by  the Committee pursuant to
the provisions of the Plan.
 
    (i) Notwithstanding any other  provision of the Plan,  if any right  granted
pursuant  to this Plan would make a Change in Control transaction ineligible for
pooling of interests accounting under
 
                                      D-14
<PAGE>
APB No. 16 that but for the nature of such grant would otherwise be eligible for
such accounting treatment, the  Committee shall have  the ability to  substitute
for the cash payable pursuant to such grant Common Stock (or the common stock of
the  issuer for  which the  Common Stock  is being  exchanged in  such Change in
Control transaction)  with a  Fair Market  Value equal  to the  cash that  would
otherwise be payable hereunder.
 
    (j)   The  Plan and all  Awards made  and actions taken  thereunder shall be
governed by and construed in accordance with the laws of the State of  Missouri,
without reference to principles of conflict of laws.
 
    Section  14.  EFFECTIVE  DATE OF PLAN.   The Plan shall  be effective at the
Effective Time, but only if it is previously approved by the affirmative vote of
the holders of a majority of the securities of KCPL present, or represented, and
entitled to vote at a meeting duly  held in accordance with the applicable  laws
of the state of Missouri.

                                  ELIGIBILITY
 
    The  Committee shall, in  its sole discretion,  determine for each Incentive
Period those officers and salaried employees  of the Company and its  Affiliates
who  shall be eligible to participate in  the Plan (the "Participants") for such
Incentive Period based upon such Participants' opportunity to have a substantial
impact on  the  operating  results  of the  Company  or  an  Affiliate.  Nothing
contained  in the Plan shall  be construed as or be  evidence of any contract of
employment with any Participant for a term of any length nor shall participation
in the  Plan  in any  Incentive  Period  by any  Participant  require  continued
participation by such Participant in any subsequent Incentive Period.
 
                                       V
                       DETERMINATION OF INCENTIVE AWARDS
 
    Subject  to Article IX hereof, the amount  and terms of each Incentive Award
to a Participant shall be determined by and in the discretion of the  Committee.
The  Committee  may  condition  the  earning  of  an  Incentive  Award  upon the
attainment of  specified performance  goals, measured  over a  period ending  no
later  than the end  of the applicable Incentive  Period. Such performance goals
may relate to  the Participant  or the Company,  or any  Affiliate, division  or
department  of  the Company  for or  within which  the Participant  is primarily
employed, or  upon  such  other  factors or  criteria  as  the  Committee  shall
determine,  and may be different for  each Participant. Incentive Awards payable
under the  Plan  will  consist of  an  award  from the  Company,  based  upon  a
percentage  (which  may  exceed 100%)  of  the  Target Incentive  Award  and, if
applicable, the  degree  of achievement  of  such performance  goals.  Incentive
Awards  under this Plan for Covered Employees shall be subject to preestablished
Performance Goals in accordance with Article  IX hereof. Except with respect  to
Covered  Employees,  the  Committee may,  in  its sole  discretion,  increase or
decrease the amount  of any  Incentive Award payable  to a  participant and,  in
recognition  of changed or special circumstances,  may award Incentive Awards to
Participants even though the Incentive  Awards are not earned. Incentive  Awards
earned or otherwise awarded will be paid as soon as administratively feasible on
or  after  the Payment  Date. Incentive  Awards  shall be  paid in  cash, shares
(including restricted shares) of the Company's common stock, par value $.01  per
share,  or in  such combination  of cash and  shares or  such other  form as the
Committee shall determine.

                           TERMINATION OF EMPLOYMENT
 
    In the  event that  a  Participant's employment  with  the Company  and  its
Affiliates terminates for any reason during the Incentive Period with respect to
any Incentive Awards, the balance of any Incentive Award which remains unpaid at
the  time of such termination shall be  payable to the Participant, or forfeited
by the Participant, in  accordance with the  terms of the  award granted by  the
Committee;  PROVIDED, HOWEVER, that  in the case  of a Covered  Employee, to the
extent necessary  for  such  amount to  be  deductible  by the  Company  or  its
affiliates,  no  amount  shall  be  payable  pursuant  to  the  Plan  unless the
Performance Goals are satisfied or the termination of employment of the  Covered
Employee  is  due to  death or  disability. A  Participant who  remains employed
through the Incentive Period but is  terminated prior to the Payment Date  shall
be  entitled to  receive any  Incentive Award  payable to  such Participant with
respect to such Incentive Period.
 
                                      VII
                          AMENDMENT AND DISCONTINUANCE
 
    The Board shall  have the right  to amend, alter,  discontinue or  otherwise
modify  the Plan from time  to time but no  such modification shall, without the
consent of  the  Participant  affected,  impair any  award  made  prior  to  the
effective date of the modification.
 
                                      VIII
                                 MISCELLANEOUS
 
    It  is presently  intended that the  Plan constitute an  "unfunded" plan for
incentive and deferred compensation. The Committee may authorize the creation of
trusts or other arrangements to meet  the payment obligations created under  the
Plan;  PROVIDED, HOWEVER, that,  unless the Committee  otherwise determines, the
existence of such  trusts or  other arrangements  shall be  consistent with  the
"unfunded"  status of the Plan.  The Plan shall be  governed by and construed in
accordance with  the  laws of  the  State of  Missouri,  without regard  to  its
principles of conflict of laws.
 
                                       IX
                 PROCEDURES FOR CERTAIN DESIGNATED PARTICIPANTS
 
    Incentive  Awards under the  Plan to Participants  who are Covered Employees
shall be  subject  to preestablished  Performance  Goals as  set  forth  herein.
Notwithstanding  Article V  hereof, the Committee  shall not  have discretion to
modify the terms of awards to such Participants except as specifically set forth
in this Article IX.
 
    (a)  TARGET BONUS.  On or before the 90th day of each Incentive Period,  and
in  any  event before  25%  or more  of the  Incentive  Period has  elapsed, the
Committee  shall  establish  in  writing  specific  Performance  Goals  for  the
Incentive  Period, upon the attainment of  which will be conditioned the payment
of Incentive Awards ("Special Incentive Awards") to such of the Participants who
may be Covered Employees.  A Special Incentive Award  shall consist of an  award
from  the Company  to be based  upon a percentage  (which may exceed  100%) of a
Target Incentive Award. The extent, if  any, to which a Special Incentive  Award
will  be payable will be based upon  the degree of achievement of preestablished
Performance Goals over a specified Incentive Period; PROVIDED, HOWEVER, that the
Committee may, in its sole discretion,  reduce the amount which would  otherwise
be payable with respect to an Incentive Period.
 
    (b)   INCENTIVE  PERIOD.   The Incentive Period  will be  a period  of up to
twelve months, unless a shorter period is otherwise selected and established  in
writing  by the Committee at the time the Performance Goals are established with
respect to such Incentive Period.
 
                                      E-4
<PAGE>
    (c)  PERFORMANCE GOALS.  The Performance Goals established by the  Committee
at the time a Special Incentive Award is granted will be based on one or more of
the  following: earnings per share, market share, stock price, sales, costs, net
operating income,  cash flow,  retained earnings,  return on  equity, return  on
assets,   economic  value  added,  results  of  customer  satisfaction  surveys,
aggregate product price and other product price measures, safety record, service
reliability,   demand-side   management   (including   conservation   and   load
management),  operating  and  maintenance  cost  management,  energy  production
availability, and individual performance  measures; PROVIDED, HOWEVER, that  all
Performance   Goals  shall   be  objective  performance   goals  satisfying  the
requirements for "performance-based compensation" within the meaning of  Section
162(m)(4)  of  the  Code.  Such  Performance Goals  also  may  be  based  on the
attainment of levels of performance of  the Company and/or any Affiliates  under
one or more of the measures described above relative to the performance of other
corporations.
 
    (d)  PAYMENT OF AN INCENTIVE AWARD.  At the time the Special Incentive Award
is  granted, the Committee shall prescribe a formula to determine the percentage
of the Target  Incentive Award which  may be  payable based upon  the degree  of
attainment  of the Performance Goals during the Incentive Period. If the minimum
Performance Goals established by the Committee  are not met, no payment will  be
made  to a Participant who is a Covered Employee. To the extent that the minimum
Performance Goals are satisfied or surpassed, and upon written certification  by
the  Committee that  the Performance Goals  have been satisfied  to a particular
extent and any  other material  terms and  conditions of  the Special  Incentive
Awards  have  been satisfied,  payment  shall be  made  on the  Payment  Date in
accordance with the  prescribed formula based  upon a percentage  of the  Target
Incentive  Award unless  the Committee  determines, in  its sole  discretion, to
reduce the payment to be made.
 
    (e)  MAXIMUM  PAYABLE.   The maximum amount  payable to  a Covered  Employee
under  this Plan for any fiscal year of  the Company pursuant to this Plan shall
be $3,000,000.
 
                                       X
                               CHANGE IN CONTROL
 
    Notwithstanding any  other provision  of this  Plan, (i)  upon a  Change  in
Control,  each  Participant  who is  employed  by  the Company  or  an Affiliate
immediately before the Change in Control shall be entitled to receive a  payment
equal  to  his or  her  Target Incentive  Award  for the  Incentive  Period that
includes the date of the  Change in Control, and  (ii) any Incentive Award  that
becomes  payable to such a Participant for  that Incentive Period, to the extent
that it is duplicative  of the amount  of the payment  made to such  Participant
pursuant  to clause (i) of this Article X, shall be reduced (but not below zero)
by such prior payment.
 
                                       XI
                               DEFERRAL ELECTIONS
 
    The Committee may  at its  option establish written  procedures pursuant  to
which  Participants  are  permitted to  defer  the receipt  of  Incentive Awards
payable hereunder.
 
                                      XII
                              SHAREHOLDER APPROVAL
 
    This Plan shall  not become effective  with respect to  individuals who  are
Covered  Employees unless it shall have been approved by the affirmative vote of
the holders  of  a  majority  of  the securities  of  the  Company  present,  or
represented,  and entitled to vote at a meeting duly held in accordance with the
applicable laws of the state of Missouri.

         , 199 ,  by and between  Maxim Energies, Inc.,  a Missouri  corporation
formerly known as Kansas City Power & Light Company (the "Company"), and A. Drue
Jennings (the "Executive");
 
    WHEREAS, the Executive is currently serving as Chairman, President and Chief
Executive  Officer  of  the  Company,  and the  Company  desires  to  secure the
continued employment of the Executive in accordance herewith;
 
    WHEREAS, the Company has entered into a severance agreement (the  "Severance

1996;
 
    WHEREAS, pursuant to the Amended and  Restated Agreement and Plan of  Merger
(the  "Merger Agreement"), dated as of January 19, 1996, as amended and restated
as of May 20,  1996, by and among  the Company, KC Merger  Sub Inc., a  Delaware
corporation,  UtiliCorp United Inc., a Delaware  corporation ("UCU"), and the KC

pursuant to the terms thereof;
 
    WHEREAS,  the Executive is willing  to commit himself to  be employed by the
Company on  the  terms  and conditions  herein  set  forth and  thus  to  forego
opportunities elsewhere; and
 
    WHEREAS,  the  parties  desire  to  enter into  this  Agreement,  as  of the
Effective Date, as hereinafter defined,  setting forth the terms and  conditions
for  the employment  relationship of the  Executive with the  Company during the
Employment Period (as hereinafter defined).
 
    NOW, THEREFORE,  IN  CONSIDERATION of  the  mutual premises,  covenants  and
agreements set forth below, it is hereby agreed as follows:
 
    1.  EMPLOYMENT AND TERM.
 
    (a)    EMPLOYMENT.   The Company  agrees  to employ  the Executive,  and the
Executive agrees to be employed by the Company, in accordance with the terms and
provisions of this Agreement during the term thereof (as described below).
 
    (b)  TERM.  The term of this Agreement shall commence as of the Closing Date
(the "Effective Date") of the "UCU Merger" (as defined in the Merger  Agreement)
and  shall continue until the fifth anniversary of the Effective Date (such term
being referred to hereinafter as the "Employment Period"); and FURTHER PROVIDED,
HOWEVER, that if the Merger Agreement is  terminated, then, at the time of  such
termination, this Agreement shall be deemed cancelled and of no force or effect.
As  a  condition to  the "Mergers"  (as  defined in  the Merger  Agreement), the
parties hereto  agree that  the Company  shall  be responsible  for all  of  the
premises, covenants and agreements set forth in this Agreement.
 
    2.  DUTIES AND POWERS OF EXECUTIVE.
 
    (A)   POSITION; LOCATION.  During the Employment Period, the Executive shall
serve from  the  Effective  Date  until  the  date  of  the  annual  meeting  of
shareholders of the Company that occurs in 2002, as the Chairman of the Board of
Directors  of  the  Company  (the  "Board")  with  such  authority,  duties  and
responsibilities with respect to such position as set forth on Annex A  attached
hereto,  and thereafter the  Executive shall serve  as the Vice  Chairman of the
Board with  such authority,  duties and  responsibilities with  respect to  such
position  as set forth on Annex A attached hereto. The titles, authority, duties
and responsibilities set forth  in Annex A attached  hereto may be changed  from
time to time but only with the mutual written agreement of the Executive and the
Company.  The Executive's services shall be performed primarily at the Company's
headquarters which shall be located in the Kansas City metropolitan area.
 
                                      F-1
<PAGE>
    (b)  BOARD MEMBERSHIP.  The Executive shall be a member of the Board on  the
first  day of the Employment  Period, and the Board  shall propose the Executive
for re-election to the Board throughout the Employment Period.
 
    (c)  ATTENTION.  During the Employment Period, and excluding any periods  of
vacation  and sick leave to which the Executive is entitled, the Executive shall
devote reasonable  attention  and  time  during normal  business  hours  to  the
business  and affairs of the  Company and, to the  extent necessary to discharge
the responsibilities assigned  to the  Executive under this  Agreement, use  the
Executive's   reasonable  best  efforts  to   carry  out  such  responsibilities
faithfully and  efficiently. It  shall  not be  considered  a violation  of  the
foregoing for the Executive to serve on corporate, industry, civic or charitable
boards  or committees, so long as such activities do not significantly interfere
with the performance of the Executive's  responsibilities as an employee of  the
Company in accordance with this Agreement.
 
    3.   COMPENSATION.   The Executive shall  receive the following compensation
for his services hereunder to the Company:
 
        (a)  SALARY.  During the Employment Period, the Executive's annual  base
    salary  (the "Annual Base Salary"), payable in accordance with the Company's
    general payroll practices,  in effect  from time to  time, shall  be at  the
    annual  rate established by the Board, but in no event less than the greater
    of his annual base salary with the Company as in effect as of the day before
    the Effective Date and the annual base salary of any other senior  executive
    officer  of the Company or its subsidiaries. The Board may from time to time
    direct such upward adjustments in Annual  Base Salary as the Board deems  to
    be  necessary or  desirable, including,  without limitation,  adjustments in
    order to reflect  increases in the  cost of living.  The Annual Base  Salary
    shall not be reduced after any increase thereof. Any increase in Annual Base
    Salary  shall  not serve  to limit  or  reduce any  other obligation  of the
    Company under this Agreement.
 
        (b)    INCENTIVE  COMPENSATION.    During  the  Employment  Period,  the
    Executive  shall participate in short-term  incentive compensation plans and
    long-term incentive  compensation  plans (the  latter  to consist  of  plans
    offering  stock  options,  restricted stock  and  other  long-term incentive
    compensation) providing him with the opportunity to earn, on a  year-by-year
    basis,  short-term  and  long-term  incentive  compensation  (the "Incentive
    Compensation") at least equal to the greater of (i) the amounts that he  had
    the  opportunity to  earn under  the comparable plans  of the  Company as in
    effect immediately before the Effective Time,  or (ii) the amounts that  any
    other  senior executive officer  of the Company has  the opportunity to earn
    under the plans of the Company and its subsidiaries for that year.
 
        (c)  RETIREMENT, INCENTIVE  AND WELFARE BENEFIT PLANS.   In addition  to
    3(b),  during the Employment Period and so long as the Executive is employed
    by the Company, he shall be eligible to participate in all other  incentive,
    stock  option, restricted  stock, performance unit,  savings, retirement and
    welfare plans,  practices, policies  and  programs applicable  generally  to
    employees   and/or  senior  executive  officers   of  the  Company  and  its
    subsidiaries, except with respect to any benefits under any plan,  practice,
    policy  or program to which the Executive  has waived his rights in writing.
    Notwithstanding anything in this Agreement to the contrary, and in  addition
    to  any  other  payments or  benefits  provided hereunder,  for  all periods
    following the termination of the  Executive's employment (i) for any  reason
    during  the term of this Agreement but after the Executive has satisfied the
    requirements for early retirement under any retirement plans or arrangements
    maintained by the  Company, as in  effect on  the Effective Date  or by  the
    Company  after the Effective  Date (the "Plans")  or (ii) at  any other time
    upon the consent of the Board, the Company shall provide the Executive (and,
    if elected  by  the  Executive  pursuant  to  the  following  sentence,  his
    designated  beneficiary) with retirement income, in addition to any benefits
    provided under the Plans, in an amount each year during the Executive's life
    (and, if elected by  the Executive pursuant to  the following sentence,  the
    life of his designated beneficiary) equal to the
 
                                      F-2
<PAGE>
    excess,  if any, of (i)  sixty percent (60%) of  the Executive's Annual Base
    Salary in effect immediately prior to his termination of employment (reduced
    based  upon  the   actuarial  assumptions   set  forth   in  the   Company's
    tax-qualified  defined benefit retirement plan (the "Qualified Plan") if the
    Executive elects  a form  of  benefit payment  other  than a  straight  life
    annuity  pursuant to the following sentence)  over (ii) the aggregate amount
    of retirement income,  if any, that  would have been  paid to the  Executive
    under  the Plans during such  year had the Executive  elected to receive his
    benefits thereunder in the  same form as he  elects to receive his  benefits
    hereunder  pursuant to  the following sentence.  The Executive  may elect to
    receive the amounts payable pursuant to  the preceding sentence in any  form
    permitted under the Qualified Plan. Such election must be made not less than
    90 days preceding the payment of any such benefits. In addition, the Company
    shall assume and continue the Severance Agreement.
 
        (d)  INSURANCE.  During the Employment Period, the Company shall provide
    the Executive with life insurance coverage providing a death benefit to such
    beneficiary or beneficiaries as the Executive may designate of not less than
    three times his Annual Base Salary.
 
        (e)    EXPENSES.   The  Company shall  reimburse  the Executive  for all
    expenses, including those for travel and entertainment, properly incurred by
    him in the performance of his  duties hereunder in accordance with  policies
    established from time to time by the Board.
 
        (f)   FRINGE BENEFITS.  During the  Employment Period and so long as the
    Executive is employed by the Company, he shall be entitled to receive fringe
    benefits in accordance with the  plans, practices, programs and policies  of
    the  Company from time to time in effect, commensurate with his position and
    at least the same as those received  by any senior executive officer of  the
    Company.
 
    4.  TERMINATION OF EMPLOYMENT.
 
    (a)   DEATH.  The Executive's  employment shall terminate automatically upon
the Executive's death during the Employment Period.
 
    (b)  BY THE COMPANY  FOR CAUSE.  The  Company may terminate the  Executive's
employment  during  the  Employment  Period  for  Cause.  For  purposes  of this
Agreement, "Cause" shall mean the conviction of the Executive for the commission
of a felony  which, at the  time of  such commission, has  a materially  adverse
effect on the Company.
 
    (c)   BY THE COMPANY WITHOUT CAUSE.   Notwithstanding any other provision of
this Agreement, the Company may terminate the Executive's employment other  than
by  a termination  for Cause  during the  Employment Period,  but only  upon the
affirmative vote of two-thirds of the membership of the Board.
 
    (d)  BY  THE EXECUTIVE FOR  GOOD REASON.   The Executive  may terminate  his
employment  during the Employment  Period for Good Reason.  For purposes of this
Agreement, "Good Reason" shall mean:
 
        (i) the reduction in the Executive's Annual Base Salary as specified  in
    Section  3(a)  of  this Agreement,  the  Executive's  Incentive Compensation
    benefit as specified in Section 3(b) of this Agreement, or any other benefit
    or payment described in Section 3 of this Agreement;
 
        (ii) the  change  without the  Executive's  consent of  the  Executive's
    title, authority, duties or responsibilities as specified in Section 2(a) of
    this Agreement;
 
       (iii)  the Company's  requiring the Executive  without his  consent to be
    based at any office or location other than the Company's headquarters  which
    shall be located in the Kansas City metropolitan area; or
 
       (iv)  any breach by the  Company of any other  material provision of this
    Agreement;
 
                                      F-3
<PAGE>
PROVIDED, HOWEVER,  that  during  the  30-day period  commencing  on  the  third
anniversary  of the  Effective Date,  the termination  by the  Executive for any
reason shall constitute  a termination by  the Executive of  his employment  for
Good Reason.
 
    (e)  NOTICE OF TERMINATION.  Any termination by the Company for Cause, or by
the Executive for Good Reason, shall be communicated by Notice of Termination to
the other party hereto given in accordance with Section 10(b) of this Agreement.
For purposes of this Agreement, a "Notice of Termination" means a written notice
which  (i) indicates the specific termination provision in this Agreement relied
upon, (ii) to the extent applicable,  sets forth in reasonable detail the  facts
and  circumstances claimed to provide a basis for termination of the Executive's
employment  under  the  provision  so  indicated,  and  (iii)  if  the  Date  of
Termination  (as defined in Section  4(f)) is other than  the date of receipt of
such notice, specifies the termination date  (which date shall be not more  than
30  days after the giving  of such notice). The failure  by the Executive or the
Company to set forth in the Notice of Termination any fact or circumstance which
contributes to a showing of  Good Reason or Cause shall  not waive any right  of
the  Executive or the Company hereunder or preclude the Executive or the Company
from asserting such  fact or circumstance  in enforcing the  Executive's or  the
Company's rights hereunder.
 
    (f)    DATE  OF  TERMINATION.    "Date  of  Termination"  means  (i)  if the
Executive's employment  is  terminated by  the  Company  for Cause,  or  by  the
Executive  for Good Reason, the date of  receipt of the Notice of Termination or
any later date specified therein,  as the case may  be, (ii) if the  Executive's
employment  is  terminated by  the Company  other  than for  Cause, the  Date of
Termination shall be  the date on  which the Company  notifies the Executive  of
such termination and (iii) if the Executive's employment is terminated by reason
of death, the Date of Termination shall be the date of death.
 
    5.  OBLIGATIONS OF THE COMPANY UPON TERMINATION.
 
    (a)  TERMINATION OTHER THAN FOR CAUSE.  During the Employment Period, if the
Company  shall terminate the Executive's employment (other than in the case of a
termination for Cause), the  Executive shall terminate  his employment for  Good
Reason  or  the  Executive's  employment  shall  terminate  by  reason  of death
(termination in any such case being referred to as a "Termination"):
 
        (i) the Company shall  pay to the  Executive a lump  sum amount in  cash
    equal  to the sum of (A) the Executive's Annual Base Salary through the Date
    of Termination to the  extent not theretofore paid,  (B) an amount equal  to
    the  Incentive  Compensation  benefit  described  in  Section  3(b)  of this
    Agreement for  the  fiscal  year  that  includes  the  Date  of  Termination
    multiplied  by a fraction the numerator of which shall be the number of days
    from the  beginning  of  such fiscal  year  to  and including  the  Date  of
    Termination  and  the  denominator  of  which  shall  be  365,  and  (C) any
    compensation previously deferred by the Executive (together with any accrued
    interest or earnings thereon) and any accrued vacation pay, in each case  to
    the  extent not theretofore paid. (The amounts specified in clauses (A), (B)
    and (C) shall be hereinafter referred to as the "Accrued Obligations".)  The
    amounts specified in this Section 5(a)(i) shall be paid within 30 days after
    the Date of Termination; and
 
        (ii) in the event of Termination other than by reason of the Executive's
    death, then (A) the Company shall pay to the Executive a lump sum amount, in
    cash, equal to the present value of the Annual Base Salary and the Incentive
    Compensation  benefit described  in Section  3(b) of  this Agreement payable
    through the end  of the Employment  Period or,  if longer, for  a period  of
    three years (the "Continuation Period"), each, at the rate, in effect at the
    time  Notice of  Termination is  given, and,  with respect  to the Incentive
    Compensation, assuming the full achievement of all target performance  goals
    in effect at the time that Notice of Termination is given, such amount to be
    paid  within 30 days of such Date of Termination; (B) except with respect to
    the benefits provided pursuant to clause (d) below, the Company shall pay to
    the Executive the value  of all benefits to  which the Executive would  have
    been entitled under Sections 3(d) and (f) had he remained in employment with
    the  Company until the end of the Continuation Period; (C) the Company shall
    pay the  value  of all  deferred  compensation amounts  (together  with  any
    accrued
 
                                      F-4
<PAGE>
    interest  or  earnings thereon)  and all  executive life  insurance benefits
    whether or not then  vested or payable; and  (D) the Company shall  continue
    medical  and welfare benefits to the Executive and/or the Executive's family
    at least equal  to those which  would have been  provided had the  Executive
    remained  in employment  to the  end of  the Continuation  Period (excluding
    benefits to which  the Executive  has waived  his rights  in writing),  such
    benefits  to be  in accordance with  the most favorable  medical and welfare
    benefit plans,  practices, programs  or policies  (the "M&W  Plans") of  the
    Company  as in effect and applicable to  any senior executive officer of the
    Company and his or her family during the 90-day period immediately preceding
    the Date of Termination or, if more favorable to the Executive, as in effect
    at any time thereafter with respect  to any senior executive officer of  the
    Company (but on a prospective basis only unless and then only to the extent,
    such  more favorable  M&W Plans are  by their  terms retroactive); PROVIDED,
    HOWEVER, that if the Executive becomes employed with another employer and is
    eligible  to  receive  medical  or  other  welfare  benefits  under  another
    employer-provided  plan, the benefits under the M&W Plans shall be secondary
    to those provided  under such other  plan during such  applicable period  of
    eligibility.
 
    (b)  TERMINATION BY THE COMPANY FOR CAUSE OR BY THE EXECUTIVE OTHER THAN FOR
GOOD  REASON. Subject to the  provisions of Section 6  of this Agreement, if the
Executive's employment  shall  be terminated  for  Cause during  the  Employment
Period,  or if the Executive terminates  employment during the Employment Period
other than a  termination for  Good Reason, the  Company shall  have no  further
obligations  to the Executive under this  Agreement other than the obligation to
pay to the Executive the Annual Base Salary through the Date of Termination plus
the amount of any  compensation previously deferred  by the Executive  (together
with  any accrued  interest or  earnings thereon),  in each  case to  the extent
theretofore unpaid.
 
    (c)   SEVERANCE  AGREEMENT.   Notwithstanding  the foregoing,  the  benefits
provided under subsections (a) and (b) of this Section 5 shall be reduced by any
amounts paid pursuant to the Severance Agreement.
 
    6.   NONEXCLUSIVITY OF RIGHTS.   Nothing in this  Agreement shall prevent or
limit the Executive's continuing or  future participation in any benefit,  plan,
program,  policy or practice provided by the Company and for which the Executive
may qualify  (except with  respect to  any benefit  to which  the Executive  has
waived  his rights  in writing),  nor shall  anything herein  limit or otherwise
affect such  rights  as the  Executive  may have  under  any other  contract  or
agreement  entered into after the Effective Date with the Company. Amounts which
are vested benefits  or which  the Executive  is otherwise  entitled to  receive
under  any benefit,  plan, policy,  practice or program  of, or  any contract or
agreement entered into  with, the Company  shall be payable  in accordance  with
such  benefit, plan, policy, practice or program or contract or agreement except
as explicitly modified by this Agreement.
 
    7.   FULL SETTLEMENT;  MITIGATION.   The Company's  obligation to  make  the
payments provided for in this Agreement and otherwise to perform its obligations
hereunder  shall  not  be  affected by  any  set-off,  counterclaim, recoupment,
defense or other claim, right or action  which the Company may have against  the
Executive  or others. In no event shall the Executive be obligated to seek other
employment or  take  any  other action  by  way  of mitigation  of  the  amounts
(including amounts for damages for breach) payable to the Executive under any of
the provisions of this Agreement and, except as provided in Section 5(a)(ii)(D),
such  amounts shall not  be reduced whether  or not the  Executive obtains other
employment. If there occurs a dispute  between the Executive and the Company  as
to  the  interpretation, terms,  validity  or enforceability  of  (including any
dispute about  the  amount of  any  payment  pursuant to  this  Agreement)  this
Agreement,  the Company  agrees to  pay all  legal fees  and expenses  which the
Executive may reasonably incur as a result of any such dispute.
 
    8.   CONFIDENTIAL INFORMATION.   The  Executive shall  hold in  a  fiduciary
capacity  for the benefit  of the Company  all secret, confidential information,
knowledge or data relating  to the Company or  any of its affiliated  companies,
and their respective businesses, which shall have been obtained by the Executive
during  the  Executive's employment  by  the Company  or  any of  its affiliated
companies (either before or  after the Effective Date)  and that shall not  have
been or now or hereafter have
 
                                      F-5
<PAGE>
become  public knowledge (other than by acts by the Executive or representatives
of the Executive in violation of this Agreement). During the Employment  Period,
the  Executive shall not, without the prior written consent of the Company or as
may otherwise be required  by law or legal  process, communicate or divulge  any
such  information, knowledge or data to anyone  other than the Company and those
designated by it.
 
    9.  SUCCESSORS.
 
    (a)  ASSIGNMENT BY EXECUTIVE.   This Agreement is personal to the  Executive
and  without the prior written consent of the Company shall not be assignable by
the Executive otherwise than  by will or the  laws of descent and  distribution.
This  Agreement  shall  inure  to  the benefit  of  and  be  enforceable  by the
Executive's legal representatives.
 
    (b)  SUCCESSORS AND ASSIGNS OF COMPANY.   This Agreement shall inure to  the
benefit of and be binding upon the Company, its successors and assigns.
 
    (c)  ASSUMPTION.  The Company shall require any successor (whether direct or
indirect,   by  purchase,  merger,   consolidation  or  otherwise)   to  all  or
substantially all  of  the business  and/or  assets  of the  Company  to  assume
expressly and agree to perform this Agreement in the same manner and to the same
extent  that the Company would  be required to perform  it if no such succession
had taken place. As used in this Agreement, "Company" shall mean the Company  as
hereinbefore  defined  and  any successor  to  its businesses  and/or  assets as
aforesaid that assumes and agrees to perform this Agreement by operation of law,
or otherwise.
 
    10.  MISCELLANEOUS.
 
    (a)  GOVERNING LAW.   This Agreement shall be  governed by and construed  in
accordance  with the  laws of  the State of  Missouri, without  reference to its
principles of conflict of laws. The captions  of this Agreement are not part  of
the  provisions hereof and shall have no force or effect. This Agreement may not

    (e)   NO WAIVER.   The Executive's  or the Company's  failure to insist upon
strict compliance  with any  provision hereof  or any  other provision  of  this
Agreement  or the failure to  assert any right the  Executive or the Company may
have hereunder, including,  without limitation,  the right of  the Executive  to
terminate employment for Good Reason pursuant to Section 4(d) of this Agreement,
or  the right of the  Company to terminate the  Executive's employment for Cause
pursuant to Section 4(b) of this Agreement shall not be deemed to be a waiver of
such provision or right or any other provision or right of this Agreement.

                              EMPLOYMENT AGREEMENT
 
    EMPLOYMENT  AGREEMENT made and entered into  as of the      day of         ,
199 , by and between Maxim Energies, Inc., a Missouri corporation formerly known
as Kansas City Power & Light Company (the "Company"), and Richard C. Green,  Jr.
(the "Executive");
 
    WHEREAS, the Executive is currently serving as Chairman, President and Chief
Executive  Officer of UtiliCorp United Inc., a Delaware corporation ("UCU"), and
the Company  desires to  secure the  continued employment  of the  Executive  in
accordance herewith;
 
    WHEREAS,  UCU  has  entered  into  a  severance  agreement  (the  "Severance
Agreement") with the Executive as of October 17, 1995;
 
    WHEREAS, pursuant to the Amended and  Restated Agreement and Plan of  Merger
(the  "Merger Agreement"), dated as of January 19, 1996, as amended and restated
as of May 20,  1996, by and among  the Company, KC Merger  Sub Inc., a  Delaware
corporation,  UCU  and  KC United  Corp.,  a Delaware  corporation,  the parties
thereto have agreed to merge pursuant to the terms thereof;
 
    WHEREAS, the Executive is  willing to commit himself  to be employed by  the
Company  on  the  terms and  conditions  herein  set forth  and  thus  to forego
opportunities elsewhere; and
 
    WHEREAS, the  parties  desire  to  enter into  this  Agreement,  as  of  the
Effective  Date, as hereinafter defined, setting  forth the terms and conditions
for the employment  relationship of the  Executive with the  Company during  the
Employment Period (as hereinafter defined).
 
    NOW,  THEREFORE,  IN CONSIDERATION  of  the mutual  premises,  covenants and
agreements set forth below, it is hereby agreed as follows:
 
    1.  EMPLOYMENT AND TERM.
 
    (a)   EMPLOYMENT.   The Company  agrees  to employ  the Executive,  and  the
Executive agrees to be employed by the Company, in accordance with the terms and
provisions of this Agreement during the term thereof (as described below).
 
    (b)  TERM.  The term of this Agreement shall commence as of the Closing Date
(the  "Effective Date") of the "UCU Merger" (as defined in the Merger Agreement)
and shall continue until the fifth anniversary of the Effective Date (such  term
being referred to hereinafter as the "Employment Period"); and FURTHER PROVIDED,
HOWEVER,  that if the Merger Agreement is  terminated, then, at the time of such
termination, this Agreement shall be deemed cancelled and of no force or effect.
As a  condition to  the "Mergers"  (as  defined in  the Merger  Agreement),  the
parties hereto agree that the Company shall be responsible for all the premises,
covenants and agreements set forth in this Agreement.
 
    2.  DUTIES AND POWERS OF EXECUTIVE.
 
    (a)   POSITION; LOCATION.  During the Employment Period, the Executive shall
serve from the Effective Date  until the earlier of (i)  the date of the  annual
meeting of shareholders of the Company that occurs in 2002, and (ii) the date on
which  A.  Drue Jennings  shall  no longer  serve as  Chairman  of the  Board of
Directors of the Company  (the "Board"), as the  Vice-Chairman of the Board  and
Chief  Executive  Officer  of  the  Company  with  such  authority,  duties  and
responsibilities with respect to such positions as set forth on Annex A attached
hereto, and thereafter the  Executive shall serve as  Chairman of the Board  and
Chief  Executive  Officer  of  the  Company  with  such  authority,  duties  and
responsibilities with respect to such positions as set forth on Annex A attached
hereto. The titles, authority, duties and responsibilities set forth in Annex  A
attached  hereto  may be  changed from  time to  time but  only with  the mutual
written agreement of  the Executive  and the Company.  The Executive's  services
shall  be  performed  primarily at  the  Company's headquarters  which  shall be
located in the Kansas City metropolitan area.
 
                                      G-1
<PAGE>
    (b)  BOARD MEMBERSHIP.  The Executive shall be a member of the Board on  the
first  day of the Employment  Period, and the Board  shall propose the Executive
for re-election to the Board throughout the Employment Period.
 
    (c)  ATTENTION.  During the Employment Period, and excluding any periods  of
vacation  and sick leave to which the Executive is entitled, the Executive shall
devote reasonable  attention  and  time  during normal  business  hours  to  the
business  and affairs of the  Company and, to the  extent necessary to discharge
the responsibilities assigned  to the  Executive under this  Agreement, use  the
Executive's   reasonable  best  efforts  to   carry  out  such  responsibilities
faithfully and  efficiently. It  shall  not be  considered  a violation  of  the
foregoing for the Executive to serve on corporate, industry, civic or charitable
boards  or committees, so long as such activities do not significantly interfere
with the performance of the Executive's  responsibilities as an employee of  the
Company in accordance with this Agreement.
 
    3.   COMPENSATION.   The Executive shall  receive the following compensation
for his services hereunder to the Company:
 
        (a)  SALARY.  During the Employment Period, the Executive's annual  base
    salary  (the "Annual Base Salary"), payable in accordance with the Company's
    general payroll practices,  in effect  from time to  time, shall  be at  the
    annual  rate established by the Board, but in no event less than the greater
    of his annual base  salary with UCU as  in effect as of  the day before  the
    Effective  Date and  the annual  base salary  of any  other senior executive
    officer of the Company or its subsidiaries. The Board may from time to  time
    direct  such upward adjustments in Annual Base  Salary as the Board deems to
    be necessary  or desirable,  including, without  limitation, adjustments  in
    order  to reflect increases  in the cost  of living. The  Annual Base Salary
    shall not be reduced after any increase thereof. Any increase in the  Annual
    Base  Salary shall not serve to limit  or reduce any other obligation of the
    Company under this Agreement.
 
        (b)    INCENTIVE  COMPENSATION.    During  the  Employment  Period,  the
    Executive  shall participate in short-term  incentive compensation plans and
    long-term incentive  compensation  plans (the  latter  to consist  of  plans
    offering  stock  options,  restricted stock  and  other  long-term incentive
    compensation) providing him with the opportunity to earn, on a  year-by-year
    basis,  short-term  and  long-term  incentive  compensation  (the "Incentive
    Compensation") at least equal to the greater of (i) the amounts that he  had
    the  opportunity to  earn under  the comparable  plans of  UCU as  in effect
    immediately before the Effective  Time, or (ii) the  amounts that any  other
    senior  executive officer of  the Company has the  opportunity to earn under
    the plans of the Company and its subsidiaries for that year.
 
        (c)  RETIREMENT, INCENTIVE  AND WELFARE BENEFIT PLANS.   In addition  to
    3(b),  during the Employment Period and so long as the Executive is employed
    by the Company, he shall be eligible to participate in all other  incentive,
    stock  option, restricted  stock, performance unit,  savings, retirement and
    welfare plans,  practices, policies  and  programs applicable  generally  to
    employees   and/or  senior  executive  officers   of  the  Company  and  its
    subsidiaries, except with respect to any benefits under any plan,  practice,
    policy  or program to which the Executive  has waived his rights in writing.
    Notwithstanding anything in this Agreement to the contrary, and in  addition
    to  any  other  payments or  benefits  provided hereunder,  for  all periods
    following the termination of the  Executive's employment (i) for any  reason
    during  the term of this Agreement but after the Executive has satisfied the
    requirements for early retirement under any retirement plans or arrangements
    maintained by UCU,  as in effect  on the  Effective Date or  by the  Company
    after  the Effective Date (the  "Plans") or (ii) at  any other time upon the
    consent of  the Board,  the Company  shall provide  the Executive  (and,  if
    elected  by the Executive pursuant to the following sentence, his designated
    beneficiary) with retirement  income, in addition  to any benefits  provided
    under the Plans, in an amount each year during the Executive's life (and, if
    elected by the Executive pursuant to the following sentence, the life of his
    designated  beneficiary) equal to  the excess, if any,  of (i) sixty percent
    (60%) of the Executive's Annual Base  Salary in effect immediately prior  to
 
                                      G-2
<PAGE>
    his  termination of employment (reduced based upon the actuarial assumptions
    set forth in  the Company's  tax-qualified defined  benefit retirement  plan
    (the  "Qualified Plan")  if the Executive  elects a form  of benefit payment
    other than a straight life annuity pursuant to the following sentence)  over
    (ii) the aggregate amount of retirement income, if any, that would have been
    paid  to the Executive  under the Plans  during such year  had the Executive
    elected to receive his benefits thereunder in the same form as he elects  to
    receive  his  benefits hereunder  pursuant  to the  following  sentence. The
    Executive may elect to receive the amounts payable pursuant to the preceding
    sentence in any form permitted under the Qualified Plan. Such election  must
    be made not less than 90 days preceding the payment of any such benefits. In
    addition, the Company shall assume and continue the Severance Agreement.
 
        (d)  INSURANCE.  During the Employment Period, the Company shall provide
    the Executive with life insurance coverage providing a death benefit to such
    beneficiary or beneficiaries as the Executive may designate of not less than
    three times his Annual Base Salary.
 
        (e)    EXPENSES.   The  Company shall  reimburse  the Executive  for all
    expenses, including those for travel and entertainment, properly incurred by
    him in the performance of his  duties hereunder in accordance with  policies
    established from time to time by the Board.
 
        (f)   FRINGE BENEFITS.  During the  Employment Period and so long as the
    Executive is employed by the Company, he shall be entitled to receive fringe
    benefits in accordance with the  plans, practices, programs and policies  of
    the  Company from time to time in effect, commensurate with his position and
    at least the same as  to those received by  any senior executive officer  of
    the Company.
 
    4.  TERMINATION OF EMPLOYMENT.
 
    (a)   DEATH.  The Executive's  employment shall terminate automatically upon
the Executive's death during the Employment Period.
 
    (b)  BY THE COMPANY  FOR CAUSE.  The  Company may terminate the  Executive's
employment  during  the  Employment  Period  for  Cause.  For  purposes  of this
Agreement, "Cause" shall mean the conviction of the Executive for the commission
of a felony  which, at the  time of  such commission, has  a materially  adverse
effect on the Company.
 
    (c)   BY THE COMPANY WITHOUT CAUSE.   Notwithstanding any other provision of
this Agreement, the Company may terminate the Executive's employment other  than
by  a termination  for Cause  during the  Employment Period,  but only  upon the
affirmative vote of two-thirds of the membership of the Board.
 
    (d)  BY  THE EXECUTIVE FOR  GOOD REASON.   The Executive  may terminate  his
employment  during the Employment  Period for Good Reason.  For purposes of this
Agreement, "Good Reason" shall mean:
 
        (i) the reduction in the Executive's Annual Base Salary as specified  in
    Section  3(a)  of  this Agreement,  the  Executive's  Incentive Compensation
    benefit as specified in Section 3(b) of this Agreement, or any other benefit
    or payment described in Section 3 of this Agreement;
 
        (ii) the  change  without the  Executive's  consent of  the  Executive's
    title, authority, duties or responsibilities as specified in Section 2(a) of
    this Agreement;
 
       (iii)  the Company's  requiring the Executive  without his  consent to be
    based at any office or location other than the Company's headquarters  which
    shall be located in the Kansas City metropolitan area; or
 
       (iv)  any breach by the  Company of any other  material provision of this
    Agreement;
 
                                      G-3
<PAGE>
provided, however,  that  during  the  30-day period  commencing  on  the  third
anniversary  of the  Effective Date,  the termination  by the  Executive for any
reason shall constitute  a termination by  the Executive of  his employment  for
Good Reason.
 
    (e)  NOTICE OF TERMINATION.  Any termination by the Company for Cause, or by
the Executive for Good Reason, shall be communicated by Notice of Termination to
the other party hereto given in accordance with Section 10(b) of this Agreement.
For purposes of this Agreement, a "Notice of Termination" means a written notice
which  (i) indicates the specific termination provision in this Agreement relied
upon, (ii) to the extent applicable,  sets forth in reasonable detail the  facts
and  circumstances claimed to provide a basis for termination of the Executive's
employment  under  the  provision  so  indicated,  and  (iii)  if  the  Date  of
Termination  (as defined in Section  4(f)) is other than  the date of receipt of
such notice, specifies the termination date  (which date shall not be more  than
30  days after the giving  of such notice). The failure  by the Executive or the
Company to set forth in the Notice of Termination any fact or circumstance which
contributes to a showing of  Good Reason or Cause shall  not waive any right  of
the  Executive or the Company hereunder or preclude the Executive or the Company
from asserting such  fact or circumstance  in enforcing the  Executive's or  the
Company's rights hereunder.
 
    (f)    DATE  OF  TERMINATION.    "Date  of  Termination"  means  (i)  if the
Executive's employment  is  terminated by  the  Company  for Cause,  or  by  the
Executive  for Good Reason, the date of  receipt of the Notice of Termination or
any later date specified therein,  as the case may  be, (ii) if the  Executive's
employment  is  terminated by  the Company  other  than for  Cause, the  Date of
Termination shall be  the date on  which the Company  notifies the Executive  of
such termination and (iii) if the Executive's employment is terminated by reason
of death, the Date of Termination shall be the date of death.
 
    5.  OBLIGATIONS OF THE COMPANY UPON TERMINATION.
 
    (a)  TERMINATION OTHER THAN FOR CAUSE.  During the Employment Period, if the
Company  shall terminate the Executive's employment (other than in the case of a
termination for Cause), the  Executive shall terminate  his employment for  Good
Reason  or  the  Executive's  employment  shall  terminate  by  reason  of death
(termination in any such case being referred to as a "Termination"):
 
        (i) the Company shall  pay to the  Executive a lump  sum amount in  cash
    equal  to the sum of (A) the Executive's Annual Base Salary through the Date
    of Termination to the  extent not theretofore paid,  (B) an amount equal  to
    the  Incentive  Compensation  benefit  described  in  Section  3(b)  of this
    Agreement for  the  fiscal  year  that  includes  the  Date  of  Termination
    multiplied  by a fraction the numerator of which shall be the number of days
    from the  beginning  of  such fiscal  year  to  and including  the  Date  of
    Termination  and  the  denominator  of  which  shall  be  365,  and  (C) any
    compensation previously deferred by the Executive (together with any accrued
    interest or earnings thereon) and any accrued vacation pay, in each case  to
    the  extent not theretofore paid. (The amounts specified in clauses (A), (B)
    and (C) shall be hereinafter referred to as the "Accrued Obligations".)  The
    amounts specified in this Section 5(a)(i) shall be paid within 30 days after
    the Date of Termination; and
 
        (ii) in the event of Termination other than by reason of the Executive's
    death, then (A) the Company shall pay to the Executive a lump sum amount, in
    cash, equal to the present value of the Annual Base Salary and the Incentive
    Compensation  benefit described  in Section  3(b) of  this Agreement payable
    through the end  of the Employment  Period or,  if longer, for  a period  of
    three years (the "Continuation Period"), each, at the rate, in effect at the
    time  Notice of  Termination is  given, and,  with respect  to the Incentive
    Compensation, assuming the full achievement of all target performance  goals
    in effect at the time that Notice of Termination is given, such amount to be
    paid  within 30 days of such Date of Termination; (B) except with respect to
    the benefits provided pursuant to clause (d) below, the Company shall pay to
    the Executive the value  of all benefits to  which the Executive would  have
    been entitled under Sections 3(d) and (f) had he remained in employment with
    the  Company until the end of the Continuation Period; (C) the Company shall
    pay the  value  of all  deferred  compensation amounts  (together  with  any
    accrued
 
                                      G-4
<PAGE>
    interest  or  earnings thereon)  and all  executive life  insurance benefits
    whether or not then  vested or payable; and  (D) the Company shall  continue
    medical  and welfare benefits to the Executive and/or the Executive's family
    at least equal  to those which  would have been  provided had the  Executive
    remained  in employment  to the  end of  the Continuation  Period (excluding
    benefits to which  the Executive  has waived  his rights  in writing),  such
    benefits  to be  in accordance with  the most favorable  medical and welfare
    benefit plans,  practices, programs  or policies  (the "M&W  Plans") of  the
    Company  as in effect and applicable to  any senior executive officer of the
    Company and his or her family during the 90-day period immediately preceding
    the Date of Termination or, if more favorable to the Executive, as in effect
    at any time thereafter with respect  to any senior executive officer of  the
    Company (but on a prospective basis only unless and then only to the extent,
    such  more favorable  M&W Plans are  by their  terms retroactive); PROVIDED,
    HOWEVER, that if the Executive becomes employed with another employer and is
    eligible  to  receive  medical  or  other  welfare  benefits  under  another
    employer-provided  plan, the benefits under the M&W Plans shall be secondary
    to those provided  under such other  plan during such  applicable period  of
    eligibility.
 
    (b)  TERMINATION BY THE COMPANY FOR CAUSE OR BY THE EXECUTIVE OTHER THAN FOR
GOOD  REASON. Subject to the  provisions of Section 6  of this Agreement, if the
Executive's employment  shall  be terminated  for  Cause during  the  Employment
Period,  or if the Executive terminates  employment during the Employment Period
other than a  termination for  Good Reason, the  Company shall  have no  further
obligations  to the Executive under this  Agreement other than the obligation to
pay to the Executive the Annual Base Salary through the Date of Termination plus
the amount of any  compensation previously deferred  by the Executive  (together
with  any accrued  interest or  earnings thereon),  in each  case to  the extent
theretofore unpaid.
 
    (c)   SEVERANCE  AGREEMENT.   Notwithstanding  the foregoing,  the  benefits
provided under subsections (a) and (b) of this Section 5 shall be reduced by any
amounts paid pursuant to the Severance Agreement.
 
    6.   NONEXCLUSIVITY OF RIGHTS.   Nothing in this  Agreement shall prevent or
limit the Executive's continuing or  future participation in any benefit,  plan,
program,  policy or practice provided by the Company and for which the Executive
may qualify  (except with  respect to  any benefit  to which  the Executive  has
waived  his rights  in writing),  nor shall  anything herein  limit or otherwise
affect such  rights  as the  Executive  may have  under  any other  contract  or
agreement  entered into after the Effective Date with the Company. Amounts which
are vested benefits  or which  the Executive  is otherwise  entitled to  receive
under  any benefit,  plan, policy,  practice or program  of, or  any contract or
agreement entered into  with, the Company  shall be payable  in accordance  with
such  benefit, plan, policy, practice or program or contract or agreement except
as explicitly modified by this Agreement.
 
    7.   FULL SETTLEMENT;  MITIGATION.   The Company's  obligation to  make  the
payments provided for in this Agreement and otherwise to perform its obligations
hereunder  shall  not  be  affected by  any  set-off,  counterclaim, recoupment,
defense or other claim, right or action  which the Company may have against  the
Executive  or others. In no event shall the Executive be obligated to seek other
employment or  take  any  other action  by  way  of mitigation  of  the  amounts
(including amounts for damages for breach) payable to the Executive under any of
the provisions of this Agreement and, except as provided in Section 5(a)(ii)(D),
such  amounts shall not  be reduced whether  or not the  Executive obtains other
employment. If there occurs a dispute  between the Executive and the Company  as
to  the  interpretation, terms,  validity  or enforceability  of  (including any
dispute about  the  amount of  any  payment  pursuant to  this  Agreement)  this
Agreement,  the Company  agrees to  pay all  legal fees  and expenses  which the
Executive may reasonably incur as a result of any such dispute.
 
    8.   CONFIDENTIAL INFORMATION.   The  Executive shall  hold in  a  fiduciary
capacity  for the benefit  of the Company  all secret, confidential information,
knowledge or data relating  to the Company or  any of its affiliated  companies,
and their respective businesses, which shall have been obtained by the Executive
during  the  Executive's employment  by  UCU and  the  Company or  any  of their
affiliated
 
                                      G-5
<PAGE>
companies and that shall not  have been or now  or hereafter have become  public
knowledge  (other  than  by acts  by  the  Executive or  representatives  of the
Executive in violation  of this  Agreement). During the  Employment Period,  the
Executive  shall not, without the prior written consent of the Company or as may
otherwise be required by law or  legal process, communicate or divulge any  such
information,  knowledge  or data  to  anyone other  than  the Company  and those
designated by it.
 
    9.  SUCCESSORS.
 
    (a)  ASSIGNMENT BY EXECUTIVE.   This Agreement is personal to the  Executive
and  without the prior written consent of the Company shall not be assignable by
the Executive otherwise than  by will or the  laws of descent and  distribution.
This  Agreement  shall  inure  to  the benefit  of  and  be  enforceable  by the
Executive's legal representatives.
 
    (b)  SUCCESSORS AND ASSIGNS OF COMPANY.   This Agreement shall inure to  the
benefit of and be binding upon the Company, its successors and assigns.
 
    (c)  ASSUMPTION.  The Company shall require any successor (whether direct or

substantially all  of  the business  and/or  assets  of the  Company  to  assume
expressly and agree to perform this Agreement in the same manner and to the same
extent  that the Company would  be required to perform  it if no such succession
had taken place. As used in this Agreement, "Company" shall mean the Company  as
hereinbefore  defined  and  any successor  to  its businesses  and/or  assets as
aforesaid that assumes and agrees to perform this Agreement by operation of law,
or otherwise.
 
    10.  MISCELLANEOUS.

principles of conflict of laws. The captions  of this Agreement are not part  of

                   INFORMATION NOT REQUIRED IN THE PROSPECTUS
 
ITEM 20.  INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
    Sections  351.355(1) and  (2) of  the MGBCL  provide that  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 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 director,
officer,  employee or agent of  another corporation, partnership, joint venture,
trust or other enterprise, against  expenses, judgments, fines and amounts  paid
in  settlement actually and  reasonably incurred by him  in connection with such
action, suit  or proceeding  if  he acted  in  good faith  and  in a  manner  he
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, except that, in the case
of an action or suit by or in the right of the corporation, the corporation  may
not  indemnify such persons against  judgments and fines and  no person shall be
indemnified as to any claim, issue or matter as to which such person shall  have
been  adjudged to be liable  for negligence or misconduct  in the performance of
his duty to  the corporation unless  and only to  the extent that  the court  in
which  the  action or  suit was  brought determines  upon application  that such
person is  fairly and  reasonably  entitled to  indemnity for  proper  expenses.
Section  351.355 further provides that, to  the extent that a director, officer,
employee or agent of the corporation has  been successful in the defense of  any
such  action, suit or proceeding or any claim, issue or matter therein, he shall
be  indemnified  against  expenses,  including  attorney's  fees,  actually  and
reasonably  incurred in connection with such action, suit or proceeding. Section
351.355 also  provides  that  a  Missouri  corporation  may  provide  additional
indemnification  to  any  person  indemnifiable  under  subsection  (1)  or (2),
provided such  additional indemnification  is  authorized by  the  corporation's
articles  of incorporation or an amendment  thereto or by a shareholder-approved
by-law or  agreement, and  provided  further that  no  person shall  thereby  be
indemnified  against conduct which  was finally adjudged  to have been knowingly
fraudulent, deliberately dishonest or willful misconduct.
 
    The KCPL Charter  provides that KCPL  will indemnify to  the fullest  extent
permitted  by the MGBCL  any person made or  threatened to be made  a party to a
legal proceeding by reason  of the fact  that the person is  or was a  director,
officer  or employee of KCPL, or  is or was serving at  the request of KCPL as a
director, officer  or  employee  of another  enterprise,  against  all  expense,
liability  or  loss  (including  attorneys'  fees  and  judgments)  actually and
reasonably incurred  by  such person.  The  KCPL  Board has  the  discretion  to
indemnify  agents of KCPL under similar  terms. These indemnification rights are
not exclusive of  any other rights  to which the  person is entitled  by law  or
under  any other  KCPL authorizations.  KCPL may,  without shareholder approval,
provide its officers, directors and employees with greater indemnification  than
the  MGBCL offers, provided that such further indemnity will not be offered to a
person whose conduct was finally adjudged  to have been knowingly fraudulent  or
deliberately dishonest, or to have constituted willful misconduct.
 
    The  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  Effective  Time,  KCPL  will, 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
Effective  Time, 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 Effective Time (and whether asserted  or
claimed prior to, at or after the Effective Time) 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   Merger    Agreement.   In    the   event    of    any
 
                                      II-1
<PAGE>
such  loss, expense, claim,  damage or liability (whether  or not arising before
the Effective  Time), (i)  KCPL will  pay the  reasonable fees  and expenses  of
counsel  selected by the  Indemnified Parties, which  counsel must be reasonably
satisfactory to  KCPL,  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 MGBCL,  (ii) KCPL will  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
MGBCL, the KCPL Charter and the KCPL Bylaws will be made by independent  counsel
mutually  acceptable to KCPL and the  Indemnified Party; provided, however, that
KCPL will not be liable for any settlement effected without its written  consent
(which  consent must not be unreasonably withheld). The 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 Merger  Agreement requires that for  a period of six  years
after the Effective Time, KCPL will cause to be maintained in effect policies of
directors  and officers' liability insurance maintained  by KCPL and UCU 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 KCPL will not be required to expend in any year an amount exceeding 200% of
the annual aggregate premiums currently paid by KCPL and UCU for such insurance.
If the annual premiums of such insurance coverage exceed such amount, KCPL  will
be  obligated  to obtain  a  policy with  the  best coverage  available,  in the
reasonable judgment of the KCPL Board, for a cost not exceeding such amount. The
Merger Agreement also provides that to the fullest extent permitted by law, from
and after the Effective Time, all rights to indemnification existing in favor of
the employees, agents, directors and officers of KCPL, UCU and their  respective
Subsidiaries  with respect  to their activities  as such prior  to the Effective
Time, 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 Mergers and will continue in  full force and effect for a period  of
not less than six years from the Effective Time.
 
    The  foregoing  statements are  subject to  the  detailed provisions  of the
MGBCL, the KCPL Charter and the Merger Agreement.

ITEM 22.  UNDERTAKINGS
 
    The undersigned registrant hereby undertakes as follows:
 
    (1)  To file, during any period in  which offers or sales are being made,  a
post-effective amendment to this registration statement:
 
        (i)  To  include  any prospectus  required  by Section  10(a)(3)  of the
    Securities Act of 1933;
 
        (ii) To reflect in the prospectus any facts or events arising after  the
    effective   date  of  the   registration  statement  (or   the  most  recent
    post-effective amendment thereof) which,  individually or in the  aggregate,
    represent  a  fundamental  change  in  the  information  set  forth  in  the
    registration statement.  Notwithstanding  the  foregoing,  any  increase  or
    decrease  in  volume of  securities offered  (if the  total dollar  value of
    securities offered  would not  exceed  that which  was registered)  and  any
    deviation  from the low or high and  of the estimated maximum offering range
    may be  reflected  in the  form  of  prospectus filed  with  the  Commission
    pursuant  to Rule  424(b) if,  in the aggregate,  the changes  in volume and
    price represent no more  than a 20 percent  change in the maximum  aggregate
    offering  price set forth in the  "Calculation of Registration Fee" table in
    the effective registration statement.
 
        (iii) To include any  material information with respect  to the plan  of
    distribution  not previously disclosed in  the registration statement or any
    material change to such information in the registration statement.
 
    Provided, however, that paragraphs  (1)(i) and (1)(ii) do  not apply if  the
registration  statement is on Form S-3 or Form S-8, and the information required
to be included in a post-effective amendment by those paragraphs is contained in
periodic reports filed  with or furnished  to the Commission  by the  registrant
pursuant  to Section 13 or Section 15(d)  of the Securities Exchange Act of 1934
that are incorporated by reference in the registration statement.
 
    (2)  That, for the purpose of determining any liability under the Securities
Act of 1933,  each such post-effective  amendment shall  be deemed to  be a  new
registration  statement  relating to  the  securities offered  therein,  and the
offering of such securities at that time shall be deemed to be the initial  bona
fide offering thereof.
 
    (3)   To remove from registration by means of a post-effective amendment any
of the securities being registered which remain unsold at the termination of the
offering.
 
    (4)   That,  for  the  purposes  of  determining  any  liability  under  the
Securities  Act of 1933, each filing  of the registrant's annual report pursuant
to Section 13(a) or Section 15(d) of  the Securities Exchange Act of 1934  (and,
where  applicable,  each  filing of  an  employee benefit  plan's  annual report
pursuant to  Section 15(d)  of the  Securities  Exchange Act  of 1934)  that  is
incorporated  by reference in the registration statement shall be deemed to be a
new registration statement relating to  the securities offered therein, and  the
offering  of such securities at that time shall be deemed to be the initial bona
fide offering thereof.
 
    (5)   That prior  to  any public  reoffering  of the  securities  registered
hereunder  through use  of a  prospectus which  is a  part of  this registration
statement, by any person or party who is deemed to be an underwriter within  the
meaning  of Rule 145(c),  the issuer undertakes  that such reoffering prospectus
will contain the information called for by the applicable registration form with
respect to reofferings by persons who may be deemed underwriters, in addition to
the information called for by the other items of the applicable form.
 
    (6)  That  every prospectus:  (i) that is  filed pursuant  to paragraph  (5)
immediately preceding, or (ii) that purports to meet the requirements of Section
10(a)(3)  of the Act  and is used  in connection with  an offering of securities
subject to Rule 415, will be filed as a part of an amendment to the registration
statement and will not be used until such amendment is effective, and that,  for
purposes
 
                                      II-3
<PAGE>
of  determining  any  liability under  the  Securities  Act of  1933,  each such
post-effective amendment  shall be  deemed to  be a  new registration  statement
relating  to the securities offered therein, and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.
 
    (7)  Insofar as indemnification for liabilities arising under the Securities
Act of 1933 may be permitted  to directors, officers and controlling persons  of
the  registrant  pursuant to  the  provisions referred  to  in Item  20  of this
registration statement, or otherwise,  the registrant has  been advised that  in
the  opinion of the  Securities and Exchange  Commission such indemnification is
against public policy as expressed in the Act and is, therefore,  unenforceable.
In  the event that  a claim for indemnification  against such liabilities (other
than the payment by the registrant of  expenses incurred or paid by a  director,
officer or controlling person of the registrant in the successful defense of any
action, suit or proceeding) is asserted by such director, officer or controlling
person  in connection with the securities being registered, the registrant will,
unless in the opinion of its counsel the matter has been settled by  controlling
precedent,  submit to a  court of appropriate  jurisdiction the question whether
such indemnification by it is against public policy as expressed in the Act  and
will be governed by the final adjudication of such issue.
 
    (8)    To  respond  to  requests for  information  that  is  incorporated by
reference into the Joint Proxy  Statement/Prospectus pursuant to Item 4,  10(b),
11  or 13 of this Form, within one  business day of receipt of such request, and
to send the incorporated documents by  first class mail or other equally  prompt
means.  This includes information contained in documents filed subsequent to the
effective date of the registration statement  through the date of responding  to
the request.
 
    (9)    To supply  by  means of  a  post-effective amendment  all information
concerning a transaction, and the company being acquired involved therein,  that
was not the subject of and included in the registration statement when it became
effective.
