                                                         February   , 1997     
 
Dear Fellow ADT Shareowner:
   
  We are pleased to enclose for your consideration Western Resources' proxy
statement and GREEN proxy card relating to the special general meeting of ADT
Limited shareowners.     
   
  In the past, ADT has advised Western Resources that it is not interested in
discussing a business arrangement between ADT and Western Resources despite
the fact that Western Resources believes that such a combination could
maximize ADT's potential both in its existing security business and in the
emerging market of deregulated retail energy distribution. After careful study
and consideration, we believe that the potential benefits to ADT, Western
Resources and ADT's other shareowners can be best realized through a
combination of Western Resources and ADT. Therefore, Western Resources is
taking its proposal to combine with ADT directly to the true owners of ADT--
the ADT shareowners.     
   
  Western Resources is offering to exchange each ADT common share for $7.50 in
cash and $15.00 in Western Resources Common Stock (the "Offer"), on the terms
and subject to the conditions set forth in the enclosed Preliminary
Prospectus. ADT shareowners may receive less than $15.00 in Western Resources
Common Stock if the price of Western Resources Common Stock is less than
$29.75. The Offer is subject to certain conditions including Western
Resources' receipt of tenders of a number of ADT common shares which, together
with shares presently owned by Western Resources and its subsidiaries,
constitute a majority of the total number of ADT common shares outstanding.
Following completion of the Offer, Western Resources plans to acquire the
remaining equity interest of ADT by effecting an amalgamation of a Bermuda
subsidiary of Western Resources with and into ADT (the "Amalgamation").     
   
  The ADT board has recently taken certain actions which Western Resources
believes were designed to establish impediments to consummation of the Offer,
including the adoption of a "poison pill" shareowner rights plan pursuant to
which the associated preference share purchase rights were issued. Western
Resources believes that the ADT board of directors may be unwilling to amend
or redeem the "poison pill" and otherwise permit the Offer to be consummated.
Accordingly, Western Resources is soliciting your proxy as a shareowner of ADT
to remove the present members of the ADT board and to replace them with
nominees of Western Resources who presently intend to take all actions
necessary to expedite consummation of the Offer and the Amalgamation,
including amending or redeeming ADT's "poison pill."     
   
  Based upon the closing price of ADT common shares on December 17, 1996, the
last day prior to the public announcement of the Offer, the Offer represents a
12% premium over ADT's market price. In addition, the Offer provides ADT
shareowners with the opportunity     
<PAGE>
 
to invest in a combined company with the potential to become a market leader
in the converging energy marketing and security industries.
 
  TO RECEIVE THE BENEFITS OF THE OFFER, IT IS IMPORTANT THAT YOU VOTE THE
GREEN PROXY CARD IN FAVOR OF WESTERN RESOURCES' NOMINEES AND PROPOSALS. ONLY
YOUR LATEST-DATED PROXY WILL COUNT AT THE ADT SPECIAL MEETING.
   
  If you have any questions concerning this Proxy Statement or the Offer or
need assistance in voting your shares, please contact our Information Agent,
MacKenzie Partners, Inc. at 1-800-322-2885.     
 
                            YOUR VOTE IS ESSENTIAL
 
 IF YOU WANT THE OFFER TO SUCCEED, VOTE FOR THE WESTERN RESOURCES PROPOSALS BY
      SIGNING, DATING AND RETURNING THE ENCLOSED GREEN PROXY CARD TODAY.
 
  Thank you for your attention and support.
 
                                          Sincerely,
 
                                          /s/ John Hayes

  Western Resources has filed exchange offer materials with the Securities and
Exchange Commission and intends to make its offer directly to shareholders of
ADT Limited as soon as its registration statement has been declared effective
by the Securities and Exchange Commission.
 
  A registration statement relating to the Western Resources securities
referred to in this letter and in the accompanying proxy statement has been
filed with the Securities and Exchange Commission but has not yet become
effective. Such securities may not be sold nor may offers to buy be accepted
prior to the time the registration statement becomes effective. This letter
and the accompanying proxy statement shall not constitute an offer to sell or
the solicitation of an offer to buy nor shall there be any sale of these
securities in any state in which such offer, solicitation or sale would be
unlawful prior to registration or qualification under the securities laws of
any such state.

                            WESTERN RESOURCES, INC.
   
  This Preliminary Proxy Statement and the accompanying GREEN proxy card are
furnished by Western Resources, Inc., a Kansas corporation ("Western
Resources"), in connection with its solicitation of proxies to be voted at the
special general meeting of shareholders of ADT Limited, a company incorporated
under the laws of Bermuda ("ADT"), and at any adjournments, postponements,
continuations or reschedulings thereof (the "ADT Special Meeting"). This Proxy
Statement is first being mailed to ADT shareholders on or about        , 1997.
Westar Capital, Inc., a Kansas corporation and a wholly owned subsidiary of
Western Resources ("Westar Capital"), presently owns approximately 27% of the
Shares (as defined below). Westar Capital has requested, in accordance with
the Bye-Laws of ADT (the "ADT Bye-Laws") and Bermuda law, that the ADT Special
Meeting be convened on February 18, 1997; however, on January 7, 1997, ADT
announced that it had tentatively scheduled the ADT Special Meeting date for
July 8, 1997. Westar Capital has commenced litigation challenging the July 8,
1997 meeting date and is seeking relief to compel the board of directors of
ADT (the "ADT Board") to hold the ADT Special Meeting on or before March 20,
1997. See "Litigation." Enclosed is a copy of the Western Resources
Preliminary Prospectus, as filed with the Securities and Exchange Commission
on February 3, 1997 (the "Preliminary Prospectus"), which sets forth the terms
and conditions of the Offer (as hereinafter defined).     
 
At the ADT Special Meeting, ADT shareholders will be asked to vote upon the
following proposals:
     
  (1) The removal of all eight of the present members of the ADT Board and
      any person or persons elected or designated by any of such directors to
      fill any vacancy or newly created directorships;     
 
  (2) The reduction of the number of seats on the ADT Board to two; and
 
  (3) The election of Steven L. Kitchen and Steven A. Millstein (the "Western
      Resources Nominees") as the directors of ADT (or, if either Western
      Resources Nominee is unable to serve as a director of ADT due to death,
      disability or otherwise, any other person designated as a Western
      Resources Nominee by Western Resources).
   
  Each of the foregoing actions (collectively, the "Western Resources
Proposals") is designed to expedite consummation of Western Resources' offer
to acquire ADT for $7.50 net in cash and $15.00 in Western Resources Common
Stock (as defined below). Shareholders of ADT are being asked to vote FOR each
of the Western Resources Proposals on the accompanying GREEN proxy card.
Assuming the presence of a quorum at the ADT Special Meeting, adoption of each
of the Western Resources Proposals will require the affirmative vote of a
simple majority of Shares voted at the ADT Special Meeting. See "The Western
Resources Proposals--Voting at the ADT Special Meeting."     
 
   WESTERN RESOURCES RECOMMENDS THAT YOU VOTE FOR EACH OF THE WESTERN
RESOURCES PROPOSALS.
 
  Western Resources has filed exchange offer materials with the Securities and
Exchange Commission (the "Commission"). As soon as Western Resources'
registration statement has been declared effective by the Commission, Western
Resources and Westar Capital intend to commence an offer to exchange shares of
common stock, par value $5.00 per share, of Western Resources ("Western
Resources Common Stock"), and cash, for
<PAGE>
 
each outstanding common share, par value $ 0.10 per share (each a "Share" and
collectively, the "Shares"), of ADT, including the associated preference share
purchase rights (each, a "Right" and collectively, the "Rights") issued
pursuant to the Rights Agreement, dated as of November 6, 1996, between ADT
and Citibank, N.A., New York branch, as Rights Agent (the "Rights Agreement"),
upon the terms and subject to the conditions set forth in the Preliminary
Prospectus and in the related Letter of Transmittal (which, together with the
final Prospectus, as it may be amended or supplemented, shall constitute the
"Offer"). The term "Expiration Date" means 5:00 p.m., Eastern time, on
 , 1997, unless and until Western Resources, in its sole discretion, shall
have extended the period of time during which the Offer is open, in which
event the term "Expiration Date" shall mean the latest time and date at which
the Offer, as so extended by Western Resources, will expire.
   
  In the Offer, each Share will be entitled to receive $7.50 net in cash (the
"Cash Consideration") and that number of shares of Western Resources Common
Stock equal to the Exchange Ratio (as defined below) (the "Stock
Consideration" and, together with the Cash Consideration, the "Offer
Consideration"). The term "Exchange Ratio" means the quotient (rounded to the
nearest 1/100,000) determined by dividing $15.00 by the average of the high
and low sales prices of Western Resources Common Stock (as reported on the New
York Stock Exchange, Inc. (the "NYSE") Composite Transactions reporting system
as published in The Wall Street Journal or, if not published therein, in
another authoritative source) (the "Western Resources Average Price") on each
of the twenty consecutive trading days ending with the third trading day
immediately preceding the Expiration Date; provided, that the Exchange Ratio
shall not be greater than 0.50420. Pursuant to the Exchange Ratio, each Share
will be exchanged for $7.50 net in cash and $15.00 of Western Resources Common
Stock as long as the Western Resources Average Price is $29.75 or higher. If
the Western Resources Average Price is less than $29.75, each Share will be
exchanged for $7.50 net in cash and less than $15.00 of Western Resources
Common Stock. Western Resources Common Stock is listed for trading under the
symbol "WR" on the NYSE. On January 31, 1997, the closing price of Western
Resources Common Stock on the NYSE was $30.625. Based on such closing price,
the Exchange Ratio would be 0.48980 and each Share would be converted into
$7.50 net in cash and $15.00 of Western Resources Common Stock. The Exchange
Ratio will change as the market price of the Western Resources Common Stock
changes. Holders of Shares ("ADT Shareholders") may call (800)      any time
on or after the date hereof through the Expiration Date for the current
Exchange Ratio calculated based on the then-current Western Resources Average
Price for the twenty consecutive trading days ending with the third trading
day immediately preceding the date the call is placed. The actual Western
Resources Average Price and Exchange Ratio will be calculated as of the third
trading day immediately prior to the Expiration Date, as described above, and
a press release will be issued announcing the actual Exchange Ratio prior to
the opening of the second trading day prior to the Expiration Date (as it may
be extended from time to time).     
   
  Complete information regarding the Offer is contained in the enclosed
Preliminary Prospectus and in the Tender Offer Statement on Schedule 14D-1,
which will be filed with the Commission prior to the commencement of the
Offer. The Tender Offer Statement on Schedule 14D-1 and any amendments
thereto, including exhibits, should be available for inspection and copies
should be obtainable in the manner set forth under the caption "Certain
Information Concerning Western Resources and ADT" (except that such material
will not be available at the regional offices of the Commission or at the
offices of the NYSE).     
   
  The purpose of the Offer is to enable Western Resources to acquire control
of ADT. Western Resources presently intends, following consummation of the
Offer, to propose and seek to have ADT effect an amalgamation of a wholly
owned subsidiary of Western Resources, incorporated under the laws of Bermuda
("Bermuda Sub"), with and into ADT, pursuant to the provisions of Sections 104
through 109 of the Companies Act 1981 of Bermuda, as amended (the "Companies
Act"), with the amalgamated company operating under the name of ADT (the
"Amalgamation"). In the Amalgamation, each then outstanding Share (other than
Shares owned by Western Resources or any of its affiliates, Shares held in the
treasury of ADT (if ADT is so authorized) or by any subsidiary of ADT and
Shares owned by ADT Shareholders who perfect appraisal rights under Bermuda
law) would be cancelled in exchange for the right to receive the Offer
Consideration. A separate vote of ADT Shareholders subsequent to the ADT
Special Meeting will be required in order to approve the     
 
                                       2
<PAGE>
 
   
Amalgamation. If the Minimum Tender Condition is satisfied and the Offer is
consummated, no separate proxy solicitation of ADT Shareholders will be
required and Western Resources does not currently intend to make any such
solicitation.     
 
  THE ACCEPTANCE OF AND PAYMENT FOR SHARES BY WESTERN RESOURCES PURSUANT TO
THE OFFER IS CONDITIONED UPON ADOPTION OF THE WESTERN RESOURCES PROPOSALS.
ACCORDINGLY, APPROVAL OF THE WESTERN RESOURCES PROPOSALS AT THE ADT SPECIAL
MEETING WILL FACILITATE THE PROMPT CONSUMMATION OF THE OFFER.
 
  WESTERN RESOURCES URGES ADT SHAREHOLDERS TO PRESERVE THEIR OPPORTUNITY TO
ACCEPT THE SIGNIFICANT BENEFITS OF THE OFFER BY PROMPTLY SIGNING, DATING AND
RETURNING THE ENCLOSED GREEN PROXY CARD. YOU MUST SEPARATELY TENDER YOUR
SHARES PURSUANT TO THE OFFER IF YOU WISH TO PARTICIPATE IN THE OFFER. VOTING
FOR THE WESTERN RESOURCES PROPOSALS DOES NOT OBLIGATE YOU TO TENDER YOUR
SHARES PURSUANT TO THE OFFER, AND YOUR FAILURE TO VOTE FOR THE WESTERN
RESOURCES PROPOSALS DOES NOT PREVENT YOU FROM TENDERING YOUR SHARES PURSUANT
TO THE OFFER.

OFFER MATERIALS WITH THE SECURITIES AND EXCHANGE COMMISSION AND INTENDS TO

EXCHANGE COMMISSION. THE OFFER WILL BE MADE ONLY BY MEANS OF THE FINAL
PROSPECTUS AND THE RELATED LETTER OF TRANSMITTAL WHICH WILL BE SEPARATELY
MAILED TO ADT SHAREHOLDERS.

                        THE WESTERN RESOURCES PROPOSALS
 
THE REQUISITION
   
  On December 18, 1996, Westar Capital deposited a requisition (the
"Requisition") with ADT, pursuant to Section 74 of the Companies Act and Bye-
Law 42 of the ADT Bye-Laws, requiring the ADT Board to convene the ADT Special
Meeting so that ADT Shareholders will have the opportunity to vote on the
Western Resources Proposals. Under the Companies Act and the ADT Bye-Laws, the
ADT Board is required to convene the ADT Special Meeting. In the event that
the ADT Board does not within twenty-one days from the date of the deposit of
the Requisition convene the ADT Special Meeting, Westar Capital may itself
convene the ADT Special Meeting. Westar Capital has requested that the date of
the ADT Special Meeting be February 18, 1997; however, on January 7, 1997, ADT
announced that it had tentatively scheduled the ADT Special Meeting for July
8, 1997. Westar Capital has commenced litigation challenging the July 8, 1997
meeting date and is seeking relief to compel the ADT Board to hold the ADT
Special Meeting on or before March 20, 1997. See "Litigation."     
 
DESCRIPTION OF THE WESTERN RESOURCES PROPOSALS
 
  Western Resources is soliciting proxies in connection with the ADT Special
Meeting for the approval of the Western Resources Proposals, which are
described below. At the ADT Special Meeting, ADT Shareholders will be asked to
adopt the resolutions attached as Annex 1 hereto in order to implement the
Western Resources Proposals.
 
  (1) Removal of Directors. The Western Resources Proposals include the
removal of all eight of the present members of the ADT Board and any other
person who may be a director of ADT at the time of the ADT Special Meeting.
Pursuant to Section 93 of the Companies Act and Bye-Law 71 of the ADT Bye-
Laws, any director of ADT may be removed from office as a director by a
resolution of ADT Shareholders to that effect.
 
  (2) Reduction of the Number of Seats on the ADT Board. The Western Resources
Proposals include a proposal to reduce the number of seats on the ADT Board to
two. Section 91(1) of the Companies Act provides that the affairs of a company
shall be managed by not less than two directors. Bye-Law 52 of the ADT Bye-
Laws provides that the number of directors shall be such number, not less than
two, as the shareholders in general meeting may from time to time determine.
The ADT Board is currently comprised of eight directors.
 
  (3) Election of the Western Resources Nominees. The Western Resources
Proposals include the election as directors of ADT of the two Western
Resources Nominees named in the table below, each of whom has consented to
serve as a director, if elected, until the next annual general meeting of
shareholders of ADT and until his successor has been elected and qualified.
Westar Capital plans to nominate each of the Western Resources Nominees in
accordance with the ADT Bye-Laws which require that written notice be given of
Westar Capital's intention to propose the Western Resources Nominees for
election to the ADT Board, together with notice in writing signed by the
Western Resources Nominees of their willingness to be elected, to the
Corporate Secretary of ADT not less than 6 and not more than 28 days prior to
the day appointed for the shareholder meeting at which directors are to be
elected. In order to comply with the requirement of Bye-Law 53 of the ADT Bye-
Laws that a director of ADT own one Share, each of the Western Resources
Nominees will own at least one Share at the time of the ADT Special Meeting.
Western Resources' primary purpose in seeking to elect the Western Resources
Nominees to the ADT Board is to take all actions necessary to expedite
consummation of the Offer and the Amalgamation. The Western Resources Nominees
would also be responsible for managing the business and affairs of ADT and
intend to discharge fully their obligations under Bermuda law. Although
Western Resources has no reason to believe that any of the Western Resources
Nominees will be unable to serve as a director of ADT, if either of the
Western Resources Nominees is not available for election, the persons named as
proxies on the GREEN proxy card will vote for the election of such other
nominee or nominees as may be proposed by Western Resources.

  Schedule B sets forth certain information relating to Shares owned by the
Western Resources Nominees and certain transactions between any of them and

has also agreed to reimburse each Western Resources Nominee for his or her
reasonable out-of-pocket expenses, including reasonable fees and expenses of
counsel.
 
  THE PURPOSE OF THE WESTERN RESOURCES PROPOSALS IS TO FACILITATE CONSUMMATION
OF THE OFFER WHICH WOULD ENABLE ADT SHAREHOLDERS TO RECEIVE $7.50 NET IN CASH
AND $15.00 OF WESTERN RESOURCES COMMON STOCK (SUBJECT TO ADJUSTMENT) FOR EACH
SHARE.
 
  WESTERN RESOURCES BELIEVES THAT IT IS IN THE BEST INTERESTS OF ADT
SHAREHOLDERS TO APPROVE THE WESTERN RESOURCES PROPOSALS, INCLUDING THE
ELECTION OF THE WESTERN RESOURCES NOMINEES, AT THE ADT SPECIAL MEETING. THE
WESTERN RESOURCES NOMINEES PRESENTLY INTEND, SUBJECT TO THE FULFILLMENT OF THE
FIDUCIARY DUTIES THEY WOULD HAVE AS DIRECTORS OF ADT, TO TAKE ALL ACTIONS
NECESSARY AND DESIRABLE TO FACILITATE THE CONSUMMATION OF THE OFFER.
 
  WESTERN RESOURCES RECOMMENDS THAT YOU VOTE FOR EACH OF THE WESTERN RESOURCES
PROPOSALS.
   
  The effect of the Western Resources Proposals will be to replace the current
directors of ADT, Michael A. Ashcroft, John E. Dannenberg, Alan B. Henderson,
James S. Pasman, Jr., Stephen J. Ruzika, W. Peter Slusser, William W. Stinson
and Raymond S. Troubh, with the Western Resources Nominees. The Western
Resources Nominees are committed to taking, subject to the fulfillment of the
fiduciary duties they would have as directors of ADT, all actions necessary
and desirable to facilitate consummation of the Offer and the Amalgamation
including, among other things, (i) either redeeming the Rights or amending the
Rights Agreement to make the Rights inapplicable to the Offer, if necessary,
in order to satisfy the Rights Plan Condition, (ii) not invoking the
provisions of Bye-Law 104 or 46 of the ADT Bye-Laws (as described below) in
connection with the acquisition of Shares by Western Resources pursuant to the
Offer or otherwise, (iii) adopting and approving an agreement and plan of
amalgamation among ADT, Bermuda Sub and Western Resources pursuant to which
Bermuda Sub will amalgamate with and into ADT, with the amalgamated company
operating under the name of ADT, and     
 
                                       5

ADT Shareholders (other than Western Resources and ADT and their respective
affiliates, and ADT Shareholders who perfect appraisal rights under Bermuda
law) will receive the Offer Consideration in exchange for the cancellation of
each Share (the "Amalgamation Agreement") and (iv) proposing an amendment to
the ADT Bye-Laws providing that an amalgamation may be approved by the
affirmative vote of a simple majority of the votes cast at a general meeting
of ADT (the "Bye-Law Amendment"). Bye-Law 64 of the ADT Bye-Laws ("Bye-Law
64") restricts the ability of an ADT director to vote on, or be counted in a
quorum to consider, proposals concerning any other company in which the
director is the holder of or is beneficially interested in one percent or more
of the equity share capital or the voting rights. Bye-Law 64 will not restrict
the ability of the Western Resources Nominees to facilitate the consummation
of the Offer and the Amalgamation because any interest of the Western
Resources Nominees in the equity share capital or voting rights of either
Western Resources or Bermuda Sub will be less than one percent.     
 
VOTING AT THE ADT SPECIAL MEETING
   
  Adoption of each of the resolutions to be presented at the ADT Special
Meeting requires the affirmative vote of a simple majority of votes, assuming
the presence of a quorum of two holders of Shares present either in person or
by proxy. Such vote may be decided on a show of hands, with each ADT
Shareholder present in person or by proxy entitled to one vote, provided, that
if a poll is demanded, the required vote shall be determined by reference to
the number of Shares voted. A poll may be demanded at the ADT Special Meeting,
before or on the declaration of the result of a show of hands, by (a) the
chairman of the meeting, (b) at least three ADT Shareholders present in person
or represented by proxy, (c) any ADT Shareholder(s) present in person or
represented by proxy holding between them not less than one-tenth of the total
voting rights of the ADT Shareholders entitled to vote at the ADT Special
Meeting; (d) any ADT Shareholder(s) present in person or represented by proxy
holding Shares on which an aggregate sum has been paid up equal to not less
than one-tenth of the total sum paid up on all Shares entitled to vote at such
meeting. Western Resources and Westar Capital intend to vote Westar Capital's
Shares and those Shares for which Western Resources or its representatives
hold valid proxies at the ADT Special Meeting in favor of each of the Western
Resources Proposals.     
 
  The accompanying GREEN proxy card will be voted in accordance with your
instructions on such card at the ADT Special Meeting. You may vote FOR the
Western Resources Proposals or vote against, or abstain from voting on, the
Western Resources Proposals by marking the proper box on the GREEN proxy card
for the ADT Special Meeting. If no marking is made, you will be deemed to have
given a direction to vote the Shares represented by the GREEN proxy card FOR
the Western Resources Proposals, provided that you have signed the proxy card.
 
  WESTERN RESOURCES RECOMMENDS A VOTE FOR THE WESTERN RESOURCES PROPOSALS.
   
  It is not expected that any matter other than those referred to herein will
be brought before the ADT Special Meeting. If any other matter, including
consideration of a proposal for postponement or adjournment, is presented at
the ADT Special Meeting, the persons named in the enclosed form of proxy and
acting thereunder will vote on such matters in their discretion. However,
proxies voted against the Western Resources Proposals will be voted for any
proposal for postponement or adjournment to solicit additional proxies against
the Western Resources Proposals.

                         REASONS FOR THE SOLICITATION
 
  The purpose of this solicitation (the "Proxy Solicitation") is to remove all
of the present members of the ADT Board, to reduce the number of seats on the
ADT Board to two and to elect the Western Resources Nominees to the ADT Board
in order to expedite consummation of the Offer and the Amalgamation, which
Western Resources believes will be beneficial to both ADT and Western
Resources shareholders.
 
ENHANCED BUSINESS OPPORTUNITIES
 
  The Western Resources Board believes the combination of ADT and Western
Resources will provide significant benefits to the shareholders of both
companies. The combination of ADT's leading national presence and unmatched
brand equity in the security business and Western Resources' strong core
utility business and customer service expertise should provide the combined
entity with opportunities not available to either company on its own.
Following the Amalgamation, Western Resources intends to capitalize on these
opportunities to become one of the leading providers of energy and energy-
related products and services, including security, to homes and businesses.
   
  As deregulation continues for electric and natural gas utilities, individual
homes and businesses will have the opportunity to choose their energy
providers. As this process unfolds, companies with nationally recognized brand
names will have a significant advantage in marketing energy and energy-related
products and services. Consummation of the Offer and the Amalgamation will
position ADT to take advantage of this emerging market, as Western Resources
intends to leverage ADT's strong brand name by marketing energy and energy
related products and services to existing ADT customers and to new customers
who know and trust the ADT brand name. In the new era of deregulation,
formerly regulated utility companies that do not respond to the new realities
of the competitive energy marketplace may suffer erosion in market share,
revenues and profits as competitors enter their service territories. Although
Western Resources has been planning for the deregulation of the energy market,
increased competition for retail electricity sales may in the future reduce
Western Resources' earnings from its formerly regulated businesses. During
1995, however, Western Resources' average retail electric rates were over 9%
below the national average and continue to be competitive within the
midwestern United States. In 1997, Western Resources further reduced its
retail rates and expects to be able to retain a substantial portion of its
current sales volume in a competitive environment. Finally, Western Resources
believes that the deregulation of the energy market will prove beneficial to
Western Resources, since any potential competitive pressure in its formerly
regulated business is expected to be more than offset by the nationwide
markets which Western Resources expects to enter by bundling energy and
security services into one package.     
 
GROWTH OPPORTUNITIES IN THE SECURITY INDUSTRY
   
  The U.S. security business is a growth industry with annual revenue of $13
billion that Western Resources believes is growing at approximately 10% per
year. Many opportunities for further growth exist, particularly in the
residential segment.     
   
  Currently, the security industry serves approximately 17.4 million
residential customers in the U.S. Western Resources believes that the number
of households purchasing security alarm services each year has grown at a 13%
rate in recent years with growth expected at an annual rate of 10% through the
year 2000. This sustained growth will be driven by a combination of increased
demand for security alarm services and the low current penetration rate.
Today, only 22% of single family households and 18% of total U.S. households
have the protection provided by an electronic security alarm system. With the
advent of more reliable, less costly, equipment, which is easier to install,
the price of the average alarm system has decreased dramatically, permitting a
significantly larger segment of the population to afford this service. The
average price of a residential alarm system was $1,500 in 1990, compared with
only $1,200 in 1995. This decrease has coincided with an increased awareness
and concern over the incidence of crime, and a stronger general desire on the
part of consumers to protect their families and property. Industry estimates
project the penetration rate of the residential market segment to at least
double its current level to approximately 40% by the year 2005, which would
result in the creation of 17.6 million new residential customers.     
 
                                       7
<PAGE>
 
   
  Western Resources believes that the commercial market penetration rate is
currently 50-60%, with a continued opportunity for growth driven by the same
demand factors affecting the residential market. In addition, a large segment
of the existing customer base requires upgrading of older systems with newer
technology, and the integration of security enhancements such as access
control and closed circuit television equipment. The cost of these
technologies has decreased dramatically and now offers an economical and
reliable alternative to security guards and outdated methods of controlling
and documenting activities within the workplace.     
   
  In order to maximize these growth opportunities, successful industry
participants would ideally utilize sophisticated mass marketing techniques to
reach consumers, develop and leverage strong brand names and fully achieve the
available economies of scale. This maximization is unlikely within the current
industry structure due to its high fragmentation of providers. There are
presently approximately 9,000-11,000 alarm companies in the U.S. Although over
85% of such companies have less than $1,000,000 in annual revenue, companies
of this size currently have a 75% share of the market. Only 13% of the U.S.
market is controlled by larger companies with ADT having the largest share at
7%, which is more than three times the size of the next largest provider.     
   
  Western Resources believes that the security industry's characteristics of
rapid growth and provider fragmentation offers a unique opportunity for the
emergence of a dynamic, growth-oriented market leader. Western Resources
believes it is one of the first, and most successful, energy companies to
pursue the opportunities presented by the security business. Western
Resources' wholly owned security subsidiary, Westar Security, Inc. ("Westar
Security), has grown through acquisitions and internal growth and, following
Western Resources' recent acquisition of Westinghouse Security, Inc.
("Westinghouse Security"), a national security system monitoring company and a
wholly owned subsidiary of Westinghouse Electric Corporation ("Westinghouse"),
Western Resources' subsidiary, Westar Security, now has over 400,000 accounts
in 44 states, making it the third largest security service provider in the
country. The combination of Westar Security and Westinghouse Security with ADT
will increase ADT's current U.S. customer base of 1.6 million accounts by 25%,
a highly significant increase in the competitive and highly fragmented
security business. Western Resources believes that a combination of ADT's
leading position in the security industry with Western Resources' financial
strength and energy businesses, will expand and strengthen ADT's current
industry leadership in the security business. Western Resources intends to
take full advantage of the new technologies that are available to ADT, which
will not be limited as a result of the Offer and the Amalgamation. ADT has
indicated in its publicly filed documents that during the past few years it
has been offering energy management products and services to regulate the
temperature and lighting of customers' premises. Such services are a natural
fit with the energy and related services that Western Resources intends to
provide on a national basis through the ADT name.     
 
EXPANSION OF BRANDED ENERGY MARKETING
   
  The electric and natural gas utility industry in the United States is
rapidly evolving from a historically regulated monopolistic market to a
dynamic and competitive integrated marketplace. The 1992 Energy Policy Act
began the process of deregulation of the electricity industry by permitting
the FERC to order electric utilities to allow third parties to sell electric
power to wholesale customers over their transmission systems. Since that time
the wholesale electricity market has become increasingly competitive as
companies begin to engage in nationwide power brokerage. In addition, various
states including California and New York have taken active steps toward
allowing retail customers to purchase electric power from third party
providers. The natural gas industry has been substantially deregulated, with
FERC and many state regulators requiring local natural gas distribution
companies to allow wholesale and retail customers to purchase gas from third-
party providers. The successful providers of energy in a deregulated market
will not only provide electric or natural gas service but also a variety of
other services, including security. Western Resources believes that in the
newly deregulated environment, more sophisticated consumers will continue to
demand new and innovative options and insist on the development of more
efficient products and services to meet their energy-related needs. Western
Resources believes that its strong core utility business provides it with the
platform to offer the more efficient products and energy services that
customers will desire. Furthermore, Western Resources believes it is necessary
to continuously seek new ways to add value to its customers' lives and
businesses. Recognizing that its current     
 
                                       8
<PAGE>
 
customer base must expand beyond its existing service area, Western Resources
views every person, whether in the United States or abroad, as a potential
customer. Western Resources also recognizes that its potential to emerge as a
leading national energy and energy-related services provider is enhanced by
having a strong brand name. Western Resources has been establishing its brand
identity through the Westar Security name. The combination of Western Resources
and ADT would immediately provide an ideal brand name to capitalize on the
emerging security and energy marketplaces.
   
   The U.S. electric industry had retail revenues of approximately $200
billion, serving approximately 117 million homes and businesses, and the U.S.
natural gas retail industry had revenues of approximately $100 billion, serving
approximately 58 million homes and businesses. In Western Resources' view, the
deregulation of the energy business will result in a model similar to that used
by the long-distance telecommunications industry, with low-cost providers
serving customers throughout the country. However, unlike the long-distance
telecommunications market which is dominated by large companies with powerful
brands, today's energy market is highly fragmented. No utility company has a
market share in the U.S. greater than 6%. It is Western Resources' view that
this market fragmentation presents a superior opportunity for national industry
leaders to emerge. Western Resources believes that a combination with ADT will
give it the brand name recognition and complementary services to excel in the
emerging deregulated electric and natural gas markets.     
          
  The combination of Western Resources and ADT will allow the combined company
to integrate energy, energy related products and services, and security, into a
packaged group of products and services to homes and businesses under the
internationally recognized ADT brand name. This strategy is based upon what
Western Resources believes to be the compelling structural and operational
similarities between the energy and security businesses. From an operational
perspective, both businesses require expertise in constructing and maintaining
a highly reliable network with central service facilities and the dispatch of
trained personnel to customer locations to respond quickly to disruptions in
service. Western Resources believes that from the customer's point of view,
energy and security are both critical service streams which may be viewed as
necessities by homes and businesses. Rather than choosing a different supplier
for each service, Western Resources believes that customers will appreciate the
convenience of purchasing energy and security services as a package and paying
for them on one convenient customer statement. Western Resources is currently
putting this concept into practice in its utility service area, offering many
of its utility customers the convenience of one-stop shopping for their energy
and security needs. Following the Offer and the Amalgamation, Western Resources
plans to expand this successful concept by selling security and unregulated
energy services to ADT's customers nationwide through a unified sales and
marketing effort under the ADT brand name.     
          
  To date, ADT's management has not recognized the opportunities presented by
the deregulation of the energy market. Western Resources believes that a
combination of the strong core utility business and customer service skills of
Western Resources and the brand name, customer base and support infrastructure
of ADT will provide both the Western Resources and ADT shareholders with an
invaluable opportunity to succeed in the security and energy markets. As the
retail electric and natural gas markets become fully open to competition,
substantial opportunities exist to increase market share and to sell a menu of
integrated services which enhance the comfort and security of energy customers.

                                   THE OFFER
 
  Western Resources has filed exchange offer materials with the Commission. As
soon as Western Resources' registration statement is declared effective by the
Commission, Western Resources and Westar Capital intend to commence the Offer
in order to exchange the Offer Consideration for each outstanding Share, and
associated Right, upon the terms and subject to the conditions set forth in
the final Prospectus and in the related Letter of Transmittal.
   
  The purpose of the Offer is to enable Western Resources to acquire control
of ADT. Western Resources presently intends, following consummation of the
Offer, to propose and to seek to have ADT effect the Amalgamation. In the
Amalgamation, each then outstanding Share (other than Shares owned by Western
Resources or any of its affiliates, Shares held in the treasury of ADT (if ADT
is so authorized) or by any subsidiary of ADT and Shares owned by ADT
Shareholders who perfect appraisal rights under Bermuda law) would be
cancelled in exchange for the right to receive the Offer Consideration.     
 
OFFER PREMIUM AND DIVIDEND IMPACT
   
  Western Resources believes that the Offer is in the best interests of ADT
Shareholders because, among other things, the Offer Consideration represents a
premium to the closing price per Share on the last trading day prior to (i)
the public announcement of Westar Capital's initial investment in ADT and (ii)
the public announcement of the Offer. The following table shows the premium of
the Offer Consideration over the closing per Share price on the NYSE on the
last trading day immediately prior to such events.

  ** Based on the closing prices of Western Resources Common Stock and Shares
 on the indicated dates.     
   
  In addition to these per Share price premiums, the Offer also provides ADT
Shareholders with the opportunity to receive an ongoing cash return on their
ADT investment in the form of dividends on Western Resources Common Stock. It
has been Western Resources' past practice to return a substantial portion of
its earnings to shareholders in the form of dividends. Western Resources has
paid dividends every year since its formation in 1924 and dividends have been
increased every year since 1958 (except for 1975, in which the dividend
remained unchanged). Western Resources paid an annual dividend of $2.02 and
$2.06 per share of Western Resources Common Stock in 1995 and 1996,
respectively. In January 1997, Western Resources increased its quarterly
dividend to $0.525 for a 1997 annual indicated dividend of $2.10. Based on an
Exchange Ratio of .48980, Western Resources' 1996 dividend of $2.06 per share
of Western Resources Common Stock equates to an equivalent dividend to ADT
Shareholders of $1.01 per share, representing a dividend yield of 6.7%. Based
on such Exchange Ratio, Western Resources' 1997 annual indicated dividend of
$2.10 per share of Western Resources Common Stock equates to an equivalent
annual indicated dividend to ADT Shareholders of $1.03 per Share, representing
a dividend yield of 6.9%. Following completion of the Offer and the
Amalgamation, Western Resources plans to expand its combined security
businesses and to begin marketing unregulated energy services under the ADT
brand name as soon as market and regulatory conditions permit. Western
Resources expects to be able to fund these activities out of the cash flow of
its energy and security businesses and expects that the combination with ADT
will increase the revenues and net cash flow of Western Resources.     
          
  The issuance of shares of Western Resources Common Stock in the Offer and
the Amalgamation is expected to have a dilutive effect on Western Resources'
reported earnings per share in the short term due to the amortization of
goodwill. The goodwill to be recorded as a result of the Amalgamation is
expected to cause the payout ratio of Western Resources' dividends per share
to earnings per share (the "Payout Ratio") to increase     
 
                                      10
<PAGE>
 
   
above its historical levels. This expected temporary increase in the Payout
Ratio is not expected to have an adverse impact on Western Resources' financial
strength or ability to pay dividends since the amortization of goodwill does
not involve any cash expenditures. However, there can be no assurances that
Western Resources will maintain its past practice with respect to the payment
of dividends since the declaration of future dividends by Western Resources
will depend upon Western Resources' future earnings, cash flow and the overall
financial condition of Western Resources, among other factors.     
 
THE EXCHANGE RATIO
 
  The per Share price premium which ADT Shareholders will receive in the Offer,
and the dividend which ADT Shareholders will receive as holders of Western
Resources Common Stock, will depend on the Exchange Ratio at the time of
consummation of the Offer. Such Exchange Ratio will be determined based on the
Western Resources Average Price; provided, that the Exchange Ratio will not be
more than 0.50420 shares of Western Resources Common Stock per Share. The
amount of cash provided in the Offer will be $7.50 net per Share, regardless of
the level of the Exchange Ratio. Pursuant to the Offer, each Share will be
exchanged for $7.50 net in cash and $15.00 of Western Resources Common Stock as
long as the Western Resources Average Price is $29.75 or higher. If the Western
Resources Average Price is less than $29.75, then each Share will be exchanged
for $7.50 net in cash and less than $15.00 of Western Resources Common Stock.
   
  The following chart sets forth a range of possible Western Resources Average
Prices and the corresponding (i) Exchange Ratio, (ii) the dollar value of the
Stock Consideration to be received per Share, (iii) the dollar value of the
Cash Consideration to be received per Share, (iv) the total dollar value of the

CERTAIN CONDITIONS OF THE OFFER
 
  Western Resources' obligation to exchange the Offer Consideration for Shares
pursuant to the Offer will be conditioned upon, among other things, the
satisfaction or, where applicable, waiver of the following conditions: (i)
there being validly tendered and not withdrawn prior to the Expiration Date a
number of Shares which, together with Shares owned by Western Resources and
its affiliates, will constitute at least a majority of the total number of
outstanding Shares on a fully diluted basis (as though all options or other
securities convertible into or exercisable or exchangeable for Shares had been
so converted, exercised or exchanged) as of the date the Shares are accepted
for exchange by Western Resources pursuant to the Offer (the "Minimum Tender
Condition"), (ii) approval of the issuance of shares of Western Resources
Common Stock in connection with the Offer and the Amalgamation and approval of
an amendment to the Amended and Restated Articles of Incorporation of Western
Resources to increase the number of shares of Western Resources Common Stock
authorized for issuance, by the holders on the applicable record date (voting
as a single class) of a majority of the shares of Western Resources Common
Stock and Western Resources preferred stock outstanding (the "Western
Resources Shareholder Approval Condition"), (iii) the approval by a majority
of those Shares voting at the ADT Special Meeting of the Western Resources
Proposals (the "ADT Shareholder Approval Condition"), (iv) the ADT Board
having redeemed the Rights or amended the Rights Agreement so that the Rights
are inapplicable to the acquisition of Shares pursuant to the Offer, or
Western Resources being otherwise satisfied in its sole discretion that the
Rights are invalid or are not applicable to the acquisition of Shares pursuant
to the Offer (the "Rights Plan Condition"), (v) Western Resources and Westar
Capital being satisfied, in their sole discretion, that the provisions of Bye-
Law 104 and Bye-Law 46 of the ADT Bye-Laws do not and will not apply to
Western Resources, Westar Capital or the acquisition of Shares pursuant to the
Offer so as (A) to require Western Resources or Westar Capital to comply with
the provisions of Bye-Law 104 of the ADT Bye-Laws or (B) to prevent Western
Resources, Westar Capital or any of their affiliates from voting Shares owned
by any of them at any time (the "ADT Bye-Law Condition"), (vi) the receipt by
Westar Capital of a final judgment from a court of competent jurisdiction
declaring the Republic Warrant invalid or the expiration of the Republic
Warrant prior to the Expiration Date without having been exercised (the
"Republic Warrant Condition"), and (vii) all regulatory approvals required to
consummate the Offer 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 (the "Western Resources Board") determines will
or could be expected to materially impair the strategic and financial benefits
expected to result from the Offer (the "Regulatory Approval Condition"). For a
complete discussion of the conditions of the Offer, see "The Offer--Conditions
of the Offer" in the Preliminary Prospectus.
 
TIMING OF THE OFFER
   
  The Offer is currently scheduled to expire on      , 1997; however, it is
Western Resources' current intention to extend the Offer from time to time as
necessary until all conditions to the Offer have been satisfied or waived.
Western Resources expects that the Western Resources Shareholder Approval
Condition will be satisfied by       , 1997, the date on which it has called a
special meeting of its shareholders (the "Western Resources Special Meeting")
to approve the issuance of shares of Western Resources Common Stock in
connection with the Offer and the Amalgamation and an amendment to the Western
Resources Articles to increase the number of shares of Western Resources
Common Stock authorized for issuance. ADT has notified ADT Shareholders that
it tentatively plans to convene the ADT Special Meeting on July 8, 1997.
Westar Capital is seeking to enjoin ADT's attempt to delay the ADT Special
Meeting beyond March 20, 1997 and Western Resources expects that it will be
successful in such efforts. Western Resources currently anticipates that all
of the conditions to the Offer (other than the ADT Shareholder Approval
Condition, the Rights Plan Condition and the ADT Bye-Law Condition) will be
satisfied by the date of the ADT Special Meeting. Western Resources currently
anticipates that the ADT Shareholder Approval Condition will be satisfied at
the ADT Special Meeting and that the Rights Plan Condition and the ADT Bye-Law
Condition will be satisfied as soon as practicable thereafter. See
"Litigation."     
 
 
                                      12

THE RIGHTS AGREEMENT
 
  The Rights Plan Condition may be satisfied in a number of ways, including
the following: (i) the current ADT Board may redeem the Rights or amend the
Rights Agreement so that the Rights would not be triggered by the Offer and
the Amalgamation, (ii) following the satisfaction of the ADT Shareholder
Approval Condition, the newly elected ADT Board may, subject to its fiduciary
obligations, take such actions as may be necessary with respect to the Rights
so that they would not be triggered by the Offer and the Amalgamation, or
(iii) Western Resources may be successful in its litigation seeking, among
other things, the invalidation of the Rights or an injunction requiring the
ADT Board to redeem the Rights. See "Prospectus Summary--Litigation" and
"Litigation."
 
  Set forth below is certain additional information concerning the Rights.
 
  On November 4, 1996, the ADT Board declared a dividend of one Series A First
Preference Share Purchase Right for each Share in issue at the close of
business on November 15, 1996 and the issuance of one Right with respect to
each Share issued after such date but prior to the Distribution Date (as
defined below).
 
  The terms of the Rights are set forth in the Rights Agreement. The following
description of the Rights does not purport to be complete and is qualified in
its entirety by reference to the Rights Agreement which is further described
and filed as an exhibit to the ADT Form 8-A.
 
  After the Distribution Date, each Right entitles the holder thereof to
purchase from ADT one hundredth of a Series A First Preference Share at a
price of $90 (the "Purchase Price"), subject to adjustment for dilution. The
Rights are not exercisable and will not separate from the Shares until the
distribution date (the "Distribution Date") which occurs on the earlier to
occur of (i) the close of business on the tenth day (or such later date as may
be designated by a majority of the Continuing Directors (as defined below))
following the date of the first public announcement that a person (other than
certain persons described below) has become the beneficial owner of 15% or
more of the Shares then issued and outstanding (an "Acquiring Person") (such
date of public announcement being a "Share Acquisition Date") or (ii) the
close of business on the tenth business day (or such later date as may be
designated by a majority of the Continuing Directors) following the
commencement of a tender or exchange offer which would result in the person
making the tender or exchange offer becoming an Acquiring Person. None of ADT,
a subsidiary of ADT, an employee benefit plan of ADT or of any of its
subsidiaries or any person organized, appointed or established by ADT or any
of its subsidiaries for or pursuant to such a plan may be considered an
Acquiring Person. In addition, a person (together with its affiliates and
associates) (a "Grandfathered Person") owning 15% or more of the issued and
outstanding Shares (such person's share percentage being a "Grandfathered
Percentage") is not an Acquiring Person if such person acquired its Shares
prior to 5:00 p.m., Eastern time, on November 4, 1996, provided that such
Grandfathered Person will become an Acquiring Person if its Grandfathered
Percentage increases. Under this formulation, each of Western Resources and
Westar Capital is a "Grandfathered Person."
 
  A "Continuing Director" is defined under the Rights Agreement to be any
member of the ADT Board who, while such person is a member of the ADT Board,
is not an Acquiring Person (or an affiliate or associate thereof) or a
representative or nominee of an Acquiring Person or of any such affiliate or
associate and either (i) was a member of the ADT Board immediately prior to
the time any person becomes an Acquiring Person or (ii) subsequently becomes a
member of the ADT Board, if such person's nomination for election or election
to the ADT Board is recommended or approved by a majority of the Continuing
Directors.
 
  After any person becomes an Acquiring Person, each Right (other than Rights
beneficially owned by an Acquiring Person and its affiliates and associates,
or transferees thereof) will entitle the holder thereof to purchase, for the
Purchase Price, Shares having a market value equal to twice the Purchase
Price.
 
  In the event that, after a Share Acquisition Date, (i) ADT consolidates,
amalgamates, or otherwise combines with any other person and ADT is either not
the continuing or surviving corporation or the Shares are changed or exchanged
or (ii) ADT or one of its subsidiaries sell, or otherwise transfer, assets or
earning power aggregating
 
                                      13
<PAGE>
 
more than 50% of the assets or earning power of ADT and its subsidiaries taken
as a whole, each Right will entitle the holder thereof to purchase, for the
Purchase Price, a number of shares of common stock of the other party to such
business combination or sale having a market value equal to twice the Purchase
Price.
 
  The Rights may be redeemed at a redemption price of $.01 per Right at any
time prior to the earlier of (i) the close of business on the tenth day
following the Share Acquisition Date (or such later date as a majority of the
Continuing Directors may designate prior to such time as the Rights are no
longer redeemable) and (ii) November 14, 2005. If the Rights are to be
redeemed on or after the Share Acquisition Date after there has been a change
in the majority of the directors on the ADT Board as a result of a proxy or
consent solicitation and a participant in such solicitation has stated that
such person intends to take, or may consider taking, any action which would
result in such person becoming an Acquiring Person or would result in the
occurrence of any of the events specified in the immediately preceding
paragraph, a majority of the Continuing Directors will be required to
authorize such redemption.
 
  The Rights Agreement may be amended in any respect prior to the Distribution
Date. After the Distribution Date, the Rights Agreement may be amended in
certain respects, if such amendments would not adversely affect the interest
of the holders of Rights (other than the Acquiring Person and any of its
affiliates or associates). After an Acquiring Person has become such, to be
effective, any amendment must be approved by a majority of the Continuing
Directors.
 
  Unless previously redeemed in accordance with terms of its Agreement, the
Rights will expire on November 14, 2005.
 
  The Rights have certain anti-takeover effects. The Rights will cause
substantial dilution to a person or group of persons that attempts to acquire
ADT in a manner which causes the Rights to become exercisable.

ADT BYE-LAWS AND THE UNITED KINGDOM CITY CODE PROVISIONS
   
  Following their election, the Western Resources Nominees do not currently
intend to serve notice pursuant to Bye-Law 104 or 46 of the ADT Bye-Laws
("Bye-Law 104" and "Bye-Law 46," respectively) upon Western Resources or any
affiliate of Western Resources who, following consummation of the Offer, owns
30% or more of the Shares. Thus, in the event the Western Resources Nominees
are elected at the ADT Special Meeting, Western Resources believes that Bye-
Law 104 and Bye-Law 46 of the ADT Bye-Laws should not apply to Western
Resources or its affiliates and that the ADT Bye-Law Condition should,
therefore, be satisfied.     
 
ADT Bye-Law 104
   
  Pursuant to Bye-Law 104(1)(A) of the ADT Bye-Laws, where any person is or
becomes "interested" in Shares, whether as a result of one transaction or a
series of transactions, in circumstances in which such person would be
obligated to make an offer to shareholders of ADT or to the holders of every
class of securities convertible into, or of rights to subscribe for, share
capital of ADT under the Rules of the City Code on Take-overs and Mergers of
the United Kingdom of Great Britain and Northern Ireland, as amended (the
"City Code"), the ADT Board may require such person to make an offer under the
City Code as if the City Code applied to ADT, but so references in the City
Code to the "Panel" will be construed as if they were references to the ADT
Board. Rule 9 of the City Code, as it is applied by the ADT Bye-Laws, provides
that, except with the consent of the ADT Board, when any person (and persons
acting "in concert" with such person) acquires shares which carry 30% or more
of the voting rights of a company, such person must make an offer for all
shares of that class (whether voting or non-voting). The offer must be for
cash or offer a cash alternative, in each case at not less than the highest
price paid (in cash or otherwise) for shares of the same class by the offeror,
or anyone acting in concert with the offeror, during the offer period and
within the 12 months prior to commencement of the offer.     
 
  Pursuant to Bye-Law 104(3) of the ADT Bye-Laws, where any person is
interested, whether as a result of a series of transactions over a period of
time or not, in 30% or more of the outstanding Shares, the ADT Board may
demand that a cash offer for all of the outstanding voting or nonvoting
securities of ADT be made if the ADT Board determines that an offer pursuant
to Bye-Law 104(1)(A) of the ADT Bye-Laws is not expedient or if a person
required to make such an offer fails to do so. Pursuant to Bye-Law 104(4) of
the ADT Bye-Laws, if the ADT Board serves a notice under Bye-Law 104(3) of the
ADT Bye-Laws, the ADT Board may also require that the offeror offer to
purchase securities of ADT convertible into voting or non-voting shares of ADT
on terms considered "fair and reasonable" by the ADT Board in its sole
discretion. Such offer must be made within 30 days of the demand.
   
  Unless the ADT Board otherwise agrees, an offer for each class of ADT
capital stock under Bye-Laws 104(3) and 104(4) of the ADT Bye-Laws must be for
cash or must offer a cash alternative at not less than the highest price paid
by the offeror or any person acting in concert with it for shares of such
class within the preceding 12 months. Such offer must remain open for at least
14 days after the date on which it becomes unconditional as to acceptances,
and in the case of an offer under Bye-Law 104(3) of the ADT Bye-Laws, must
provide that all shares will be purchased within 21 days of the offer becoming
unconditional in all respects.     
 
ADT Bye-Law 46
   
  Subject to any rights or restrictions attached to any class of capital stock
of ADT, at any meeting of ADT, a shareholder present in person or by proxy is
entitled, on a poll, to one vote for each share held by such shareholder.
Pursuant to Bye-Law 46 of the ADT Bye-Laws, an ADT Shareholder is not entitled
(except as a proxy for another shareholder) to be present or to vote at any
meeting if such ADT Shareholder received a notice under Bye-Law 104 of the ADT
Bye-Laws stating that upon failure to make an offer pursuant to Bye-Law 104 of
the ADT Bye-Laws before a period of not less than 28 days from the date of
service of such notice the ADT Shareholder would not be entitled to vote and
the shareholder upon whom such notice was served (i) fails to make such an
offer within the period so specified, or (ii) having made such an offer or
acquired shares of ADT in contravention of a notice served under Bye-Law 104
of the ADT Bye-Laws, fails to remedy such noncompliance.     
 
                                      15
<PAGE>
 
   
  Neither Western Resources nor any of its subsidiaries are presently
"interested" in 30% or more of the outstanding Shares of ADT. Therefore, the
provisions of Bye-Laws 104 and 46 do not presently apply to Western Resources
or its subsidiaries. If elected, the Western Resources Nominees intend to take
all actions necessary and desirable to facilitate consummation of the Offer
and the Amalgamation, including, among other things, not invoking the
provisions of Bye-Law 104 or Bye-Law 46 of the ADT Bye-Laws in connection with
the acquisition of Shares by Western Resources pursuant to the Offer or
otherwise.     
 
  The foregoing does not purport to be a complete description of Bye-Law 104
or Bye-Law 46 of the ADT Bye-Laws. ADT Shareholders are urged to, and should,
read Bye-Law 104 and Bye-Law 46 of the ADT Bye-Laws, copies of which are
included herein as Schedules E and F, respectively.
 
  If the Offer is consummated, Western Resources and its affiliates will own a
majority of the outstanding Shares. Accordingly, Western Resources and its
affiliates will at such time have sufficient voting power in ADT to approve
the Bye-Law Amendment and the Amalgamation Agreement independently of the vote
of any other ADT Shareholders. Western Resources presently intends to vote any
and all Shares then owned by Western Resources and its affiliates to approve
such proposals.
   
  The Amalgamation will be subject to certain conditions, including the
consent of the Minister of Finance of Bermuda (the "Minister of Finance"). The
Western Resources Nominees are committed, subject to the exercise of their
fiduciary duties, as soon as practicable following the exchange of Shares by
Western Resources pursuant to the Offer, to causing all necessary actions to
be taken to seek the consent of the Minister of Finance to the Amalgamation.
Western Resources has no reason to believe that the Minister of Finance will
not grant approval for the Amalgamation; however, there can be no assurance
that the Minister of Finance would grant his consent for the Amalgamation. An
adverse decision by the Minister of Finance may not be subject to appeal or
review in any court. Western Resources also presently intends to condition the
Amalgamation upon holders of not more than 5% of the outstanding Shares at the
effective time of the Amalgamation perfecting appraisal rights with respect to
the Amalgamation pursuant to Section 106(6) of the Companies Act. See "Absence
of Appraisal Rights."

            VOTING SECURITIES OF ADT AND PRINCIPAL HOLDERS THEREOF
   
  Each Share is entitled to one vote upon each matter presented at the ADT
Special Meeting. The ADT Management Proxy Statement (as defined herein) states
that, as of December 31, 1996, there were 141,382,697 Shares outstanding,
including 3,182,787 which are owned by a subsidiary of ADT.     
   
  The following table and notes thereto, which, other than information
regarding Westar Capital, are reproduced from the ADT Management Proxy
Statement, set forth certain information with respect to beneficial ownership
of Shares (i) as of December 31, 1996 by any person known by ADT to own
beneficially more than five percent of the outstanding Shares, other than
Westar Capital, and (ii) as of December 31, 1996 by (a) all directors of ADT,
(b) the named directors and officers of ADT, including three executive
officers of subsidiaries of ADT and (c) all directors and executive officers
of ADT as a group. The following table also sets forth certain information
with respect to beneficial ownership of Shares by Westar Capital as of the
date of this Preliminary Proxy Statement. An asterisk indicates ownership of
less than one percent of outstanding Shares.

ADT
 
  The following information concerning ADT is derived from ADT's Annual Report
on Form 10-K for the period ended December 31, 1995:
 
  ADT was incorporated in Bermuda on September 28, 1984 under the name Hawley
Group Limited and is an exempted company limited by shares with its registered
office at Cedar House, 41 Cedar Avenue, Hamilton HM12 Bermuda. The executive
office of the subsidiary which supervises ADT's North American activities is
located in the United States at One Boca Place, 2255 Glades Road, Suite 421A,
Boca Raton, Florida 33431, and its telephone number is (407) 997-8406.
 
  ADT is currently engaged in two service businesses: electronic security
services in North America and Europe and vehicle auction and related services
in the United States. ADT is the largest provider of electronic security
services in North America and the largest provider in the United Kingdom,
providing continuous monitoring of commercial and residential security systems
for 1.6 million customers. ADT is also the second
 
                                      18
<PAGE>
 
largest provider of vehicle remarketing services in the United States,
operating a network of 28 vehicle auction centers.
 
  ADT's principal activities in the electronic security services businesses
are the electronic monitoring of its installed base of security systems and
the installation of new, monitored security systems to add to its installed
base. Monitored systems may be sold or, as is most often the case, ADT may
retain ownership of installed systems. ADT receives contractual recurring fees
for monitoring security systems through its electronic monitoring centers and
for maintenance of security systems installed at customer premises and other
related services. ADT sells, installs and maintains monitored security
systems, integrated electronic security systems and other electronic security
products for additional fees. In 1995, approximately 60% of ADT's total
electronic security services revenues in North America and Europe were derived
from contractually recurring fees for electronic monitoring and maintenance of
security systems installed at customer premises and other related services.
The remainder of ADT's security revenues were derived from the outright sale
and installation of security systems, the installation of security systems in
accordance with a monitoring service agreement and the maintenance of security
systems on a non-contractual basis.
 
  In September 1996, ADT acquired the entire equity interest in Automated
Security (Holdings) PLC, a United Kingdom company ("ASH"). ASH is engaged in
the provision of electronic security services in North America and Europe.
   
  In a press release issued by ADT on November 6, 1996, ADT announced its
intention to sell its United States vehicle auction business. ADT's vehicle
auction business operates a network of large modern auction centers which
provide an organized wholesale marketplace for the sale and purchase of used
vehicles. Principal sellers, or consignors, include new and used vehicle
dealers, vehicle manufacturers, fleet operators, leasing companies, financial
institutions and government agencies. Principal purchasers include franchise
and non-franchise vehicle dealers and distributors who acquire vehicles to
sell in the retail market. Western Resources does not presently possess
adequate information to formulate a position with respect to ADT's intention
to sell its U.S. vehicle auction business. If the Offer is consummated,
Western Resources would at such time evaluate its position with respect to
such proposed disposition.     
 
  Western Resources and ADT are subject to the informational requirements of
the Securities Exchange Act of 1934, as amended (the "Exchange Act"), and in
accordance therewith file reports, proxy statements and other information with
the Commission. Reports, proxy statements and other information filed by
Western Resources and ADT with the Commission may be inspected and copied at
the public reference facilities maintained by the Commission at Judiciary
Plaza, 450 Fifth Street, N.W., Room 1024, Washington, D.C. 20549 and at the
public reference facilities in the Commission's Regional Offices at Seven
World Trade Center, 13th Floor, New York, New York 10048 and Citicorp Center,
500 West Madison Street, Suite 1400, Chicago, Illinois 60661. Copies of
information may be obtained from the Public Reference Section of the
Commission at 450 Fifth Street, N.W., Washington, D.C. 20549 at prescribed
rates. The Western Resources Common Stock and the Shares are listed and traded
on the NYSE. The Shares are also listed and traded on the London Stock
Exchange, the Frankfurt Stock Exchange and the Bermuda Stock Exchange.
Reports, proxy statements and other information filed by Western Resources and
ADT with the Commission may be inspected at the offices of the NYSE, 20 Broad
Street, New York, New York 10005.
   
  Pursuant to Rule 409 promulgated under the Securities Act of 1933, as
amended, and Rule 12b-21 promulgated under the Exchange Act, Western Resources
has requested that ADT and its independent public accountants, Coopers &
Lybrand, L.L.P., provide to Western Resources the information required for
complete disclosure concerning the business, operations, financial condition
and management of ADT. Neither ADT nor Coopers & Lybrand, L.L.P. has yet
provided any information in response to such request. Western Resources will
provide any and all information which it receives from ADT or Coopers &
Lybrand, L.L.P. prior to the ADT Special Meeting and which Western Resources
deems material, reliable and appropriate in a subsequently prepared supplement
hereto.

                        BACKGROUND OF THE SOLICITATION
   
  In the past, ADT has advised Western Resources that it is not interested in
discussing a business arrangement between ADT and Western Resources despite
the fact that Western Resources believes that such a combination could
maximize ADT's potential both in its existing security business and in the
emerging market of deregulated retail energy distribution. After careful study
and consideration, Western Resources believes that the potential benefits to
ADT, Western Resources and the companies' respective shareholders can be best
realized through a combination of Western Resources and ADT, and has,
therefore, decided to proceed with the Offer.     
   
  In December 1995, Western Resources entered into a stock purchase agreement
with Laidlaw Transportation, Inc. ("Laidlaw"), and Laidlaw, Inc., pursuant to
which Westar Capital subsequently purchased a total of 30,800,000 Shares, on
or prior to March 18, 1996, at an average price of $14.40 per Share. Since
March 18, 1996, from time to time Westar Capital has purchased Shares in the
open market at prevailing market prices. Westar Capital owns 38,287,111
Shares, or approximately 27% of the outstanding Shares, including 14,115
Shares issuable upon exchange of 500 LYONs, which are exchangeable for Shares
at a rate of 28.23 Shares per LYON.     
   
  On July 1, 1996, ADT entered into an Agreement and Plan of Amalgamation (the
"Republic Agreement") with Republic Industries, Inc. ("Republic") and Republic
Sub Ltd., a newly created wholly owned subsidiary of Republic ("Republic
Sub"). Pursuant to the terms of the Republic Agreement, Republic Sub was to be
amalgamated with and into ADT with the amalgamated company operating under the
name of ADT (the "Republic Transaction"). The terms of the Republic Agreement
contemplated that ADT Shareholders would receive .92857 shares of Republic
common stock in exchange for each Share and was conditioned upon, among other
things, receipt by ADT of a fairness opinion from its financial advisor at a
later date (which fairness opinion was never obtained). Based upon the $26.75
closing price per share of Republic common stock on July 1, 1996, each Share
would have been exchangeable for approximately $24.84 worth of Republic common
stock. Following the public announcement of the Republic Transaction, the
closing price per share of Republic common stock fell to $20.75 per share.
Based on a closing price of $20.75, each Share would have been exchangeable
for approximately $19.27 worth of Republic common stock in the Republic
Transaction. On September 13, 1996, Westar Capital disclosed that it had
determined to oppose the Republic Transaction. Pursuant to the terms of the
Republic Agreement, ADT granted to Republic a warrant to subscribe for 15
million Shares at a purchase price of $20 per share, subject to adjustment
(the "Republic Warrant"). The Republic Warrant was to become exercisable for a
period of six months following the termination of the Republic Agreement. On
September 30, 1996, ADT and Republic jointly announced the termination of the
Republic Agreement citing uncertainty attributable to market conditions, and
amended the Republic Warrant to include certain restrictions on the issuance
of Shares pursuant thereto and the transfer of such Shares by Republic to
persons with interests in 10% or more of ADT. As described below, Western
Resources has commenced litigation challenging the validity of the Republic
Warrant. See "Litigation."     
   
  On September 5, 1996, the waiting period expired with respect to Western
Resources' filing under the HSR Act to acquire ownership of in excess of 25%
(but less than 50%) of the outstanding Shares.     
 
  On November 4, 1996, ADT declared a distribution of one Right for each
outstanding Share, payable to holders of record as of the close of business on
November 15, 1996, pursuant to the Rights Agreement. The Rights Agreement
provides, among other things, that after certain persons acquire 15% or more
(or, in certain limited situations, a greater percentage) of the issued and
outstanding Shares, holders of Shares (other than such persons) will be
entitled to purchase Shares at half of the current market value and that if,
after such an acquisition, ADT is involved in an amalgamation, other business
combination or certain sale transactions, holders of Shares (other than such
persons) will be entitled to purchase either Shares, or common stock of the
other party to such transaction, at half of the current market value of such
securities. See "The Offer--Conditions of the Offer--Rights Agreement" and "--
ADT Rights" in the Preliminary Prospectus.

  On November 6, 1996, ADT announced its intention to sell its United States
vehicle auction business.
 
  On December 17, 1996, the Western Resources Board met and determined to
proceed with the Offer. On December 18, 1996, in the letter set forth below to
Mr. Michael A. Ashcroft, Chairman of the Board, President and Chief Executive
Officer of ADT, Mr. John E. Hayes, Jr., Chairman of the Board and Chief
Executive Officer of Western Resources, informed Mr. Ashcroft and the ADT
Board of Western Resources' intention to pursue the Offer and the Amalgamation
and encouraged Mr. Ashcroft and the ADT Board to meet with Western Resources
to discuss the possibility of a mutually beneficial negotiated transaction.
 
 
                                              December 18, 1996
 
  Mr. Michael A. Ashcroft
  ADT Limited
  Cedar House
  41 Cedar Avenue
  Hamilton HM12
  Bermuda
 
  Dear Michael:
 
    We have demonstrated our belief in ADT's future by investing $589
  million to purchase 27% of ADT's outstanding common shares, making us
  ADT's largest shareowner. In the past you and your board have advised us
  that you are not interested in discussing a business arrangement between
  our companies that could maximize ADT's potential, both in its existing
  security business and in the emerging market of deregulated retail energy
  distribution.
 
    Now, after careful study and consideration, we have determined that the
  potential benefits to ADT, Western Resources and ADT's other shareowners
  from a combination of Western Resources and ADT are simply too compelling
  to ignore. We firmly believe that this combination will provide
  significant benefits to our respective shareowners, customers and
  employees not available to either company on its own.
 
    We believe ADT's full potential can only be realized in a strategic
  business combination. In our proposed transaction, ADT shareowners will
  become a part of one of the most innovative and dynamic companies in the
  business of making people's lives safer and more comfortable. Our
  subsidiary, Westar Security, is one of the fastest growing security
  companies in the nation. Combined with ADT, the leading brand name in the
  security industry, Western Resources will serve the energy and security
  needs of customers across the country and around the world.
 
    Western Resources, therefore, will file with the Securities and Exchange
  Commission a preliminary prospectus for an offer by Western Resources to
  ADT shareowners. Under our proposed offer, ADT shareowners (other than
  Western Resources and its affiliates) will receive $7.50 net in cash and
  $15.00 of Western Resources common stock in exchange for each ADT common
  share, up to a maximum of 0.50420 shares of Western Resources common
  stock. Based upon the closing price of ADT common shares on December 17,
  1996, our proposal represents a 12% premium above ADT's market price.
 
    In order to ensure ADT's other shareowners receive the chance to
  consider our proposal for themselves, we will also demand a special
  general meeting of ADT shareowners for the purposes of (i) removing the
  present members of the ADT board, (ii) reducing the number of seats on the
  ADT board from eight to two, and (iii) electing Western Resources'
  nominees to the ADT board. We will also file preliminary proxy materials
  relating to such special meeting. Once the Western Resources nominees are
  elected to the ADT board, Western Resources intends to consummate the
  exchange offer and a subsequent amalgamation pursuant to which Western
  Resources will acquire 100% of ADT's equity.
 
 
                                      21
<PAGE>
 
    We trust that you and the other members of ADT's board will consider the
  best interests of ADT's shareowners, customers and employees and agree to
  meet with us to achieve a mutually beneficial transaction, that ensures
  that ADT executives and employees will enjoy exciting opportunities for
  career growth with the combined company. We are, however, committed to
  achieving the strategic benefits of a business combination of ADT and
  Western Resources and prepared to take all necessary steps to ensure that
  we and ADT's other shareowners have the opportunity to decide the future
  of our investment in ADT.
 
    I look forward to hearing from you soon.
 
                                              Sincerely,
 
                                              LOGO
 
   On December 18, 1996, Western Resources also publicly announced its
intention to commence the Offer and filed this Preliminary Proxy Statement
with the Commission for use in soliciting proxies from ADT Shareholders to
approve the Western Resources Proposals at the ADT Special Meeting. On
December 18, 1996, Westar Capital deposited the Requisition with ADT,
requiring the ADT Board to convene the ADT Special Meeting.
   
  On January 7, 1997, ADT announced that it had tentatively scheduled the ADT
Special Meeting date for July 8, 1997. Westar Capital has commenced litigation
challenging the July 8, 1997 meeting date and is seeking relief to compel the
ADT Board to hold the ADT Special Meeting on or before March 20, 1997. ADT
also filed the ADT Management Proxy Statement with the Commission for use in
soliciting proxies from ADT Shareholders for the ADT Special Meeting against
the Western Resources Proposals.     
   
  On January 23, 1997, the waiting period expired with respect to Western
Resources' filing under the HSR Act to acquire ownership of up to 100% of the
outstanding Shares.     
 
                                  LITIGATION
   
  On December 18, 1996, Western Resources announced that Westar Capital had
commenced litigation in the United States District Court for the Southern
District of Florida (the "Court") charging ADT and the ADT Board with breaches
of their fiduciary duties to ADT and the ADT Shareholders. The complaint
alleged, among other things, that the ADT Board breached its fiduciary duty to
ADT and the ADT Shareholders by (i) adopting and continuing to deploy the ADT
Rights Agreement, (ii) granting the Republic Warrant in connection with the
subsequently terminated Republic Transaction for the purpose of making an
unsolicited bid for ADT more expensive and placing a block of votes under Mr.
Ashcroft's control, and (iii) placing approximately 3,182,787 Shares in an ADT
subsidiary to interfere with the voting rights of ADT's other shareholders.
Westar Capital also alleged that by agreeing to the Republic Warrant and the
amendments thereto, Republic aided and abetted breaches of fiduciary duties by
the ADT Board.     
   
  On January 3, 1997, Westar Capital filed an amended complaint alleging that
certain letters sent by ADT to Western Resources and Westar Capital interfered
with Westar Capital's voting rights as an ADT Shareholder.     
   
  On January 21, 1997, the Court granted Westar Capital's motion for leave to
file a Second Amended Complaint in which Westar Capital alleged that (i) ADT's
January 7, 1997 announcement that the ADT Special Meeting was scheduled for
July 8, 1997 violated the ADT Board's fiduciary and statutory duties under
Bermuda law and (ii) ADT's failure to file a Schedule 14D-9 Tender Offer
Statement violated Section 14(d) of the Exchange Act.     
 
 
                                      22
<PAGE>
 
   
  On January 23, 1997, Westar Capital filed a motion seeking to enjoin the ADT
Board from holding the ADT Special Meeting on July 8, 1997 and to compel the
ADT Board to hold the meeting on or before March 20, 1997. ADT has expressed
an intention to file a motion to dismiss Westar Capital's complaint on the
grounds that, among other things, the Court lacks personal jurisdiction over
ADT. Westar Capital has requested the Court to schedule expedited briefing on
its motion for a preliminary injunction.     
       
          
  On December 26, 1996, a shareholder of ADT filed a purported class action
complaint against ADT, the ADT Board, Western Resources and Westar Capital in
the Civil Division of the Circuit Court of the Fifteenth Judicial Circuit in
Palm Beach County, Florida. The complaint alleges, among other things, that
Western Resources and Westar Capital are breaching their fiduciary duties to
ADT Shareholders by failing to offer "an appropriate premium for the
controlling interest" in ADT and by holding "an effective blocking position"
that prevents independent parties from bidding for ADT. The complaint seeks
preliminary and permanent relief enjoining Western Resources from acquiring
outstanding Shares of ADT and unspecified damages. Western Resources believes
it has good and valid defenses to the claims asserted and does not anticipate
any material adverse effect on its assets or financial results arising
therefrom.     
 
                       WESTERN RESOURCES' OFFER FOR KCPL
 
  Kansas City Power & Light Company, a Missouri corporation ("KCPL"), is a
public utility engaged in the generation, transmission, distribution and sale
of electricity to approximately 430,000 customers in western Missouri and
eastern Kansas.
   
  On July 8, 1996, Western Resources commenced an offer (the "KCPL Offer") to
exchange shares of Western Resources Common Stock for each outstanding share
of common stock, without par value, of KCPL ("KCPL Common Stock"). The purpose
of the KCPL Offer is to obtain control of, and ultimately the entire equity
interest in, KCPL. Western Resources intends, as soon as practicable after
consummation of the KCPL Offer, to seek to merge KCPL with and into itself
(the "KCPL Merger"). Pursuant to the exchange ratio in the KCPL Offer, KCPL
shareholders would receive $31.00 of Western Resources Common Stock in
exchange for each share of KCPL Common Stock, subject to a maximum of 1.100
and a minimum of 0.933 shares of Western Resources Common Stock for each share
of KCPL Common Stock. According to KCPL's Quarterly Report on Form 10-Q for
the period ended September 30, 1996, as of November 5, 1996, there were
61,904,744 shares of KCPL Common Stock outstanding. Based on the number of
shares of KCPL Common Stock outstanding on November 5, 1996, if the KCPL Offer
and KCPL Merger were consummated, KCPL shareholders would receive
approximately 61,409,506 shares of Western Resources Common Stock,
representing approximately 31.5% of the total Western Resources Common Stock
(assuming that the Offer and the Amalgamation had previously been completed).
Western Resources reserves the right, in its sole discretion, at any time or
from time to time to amend or terminate the KCPL Offer in accordance with its
terms.     
 
  On November 15, 1996, representatives of Western Resources' and KCPL's
respective boards and managements met and had a cordial discussion regarding
the proposed KCPL Merger. On November 25, 1996, representatives of Western
Resources' and KCPL's respective boards and managements met again and
continued their discussions.
   
  As of January 15, 1997, the most recent expiration date for the KCPL Offer,
approximately 30.2 million shares of KCPL Common Stock, or 49% of the
outstanding shares of KCPL Common Stock, had been tendered to Western
Resources pursuant to the KCPL Offer. Western Resources believes that this
level of tenders demonstrates the support of KCPL shareholders for a merger of
Western Resources and KCPL. On January 15, 1997, Western Resources issued a
press release which stated that substantive merger negotiations are continuing
between KCPL and Western Resources. As a result of the dialogue between the
two companies, Western Resources has extended the expiration date for the KCPL
Offer to 5:00 p.m., Eastern time, on February 5, 1997 and will continue to
refrain from actively soliciting tenders of shares of KCPL Common Stock.
Although there     
 
                                      23
<PAGE>
 
   
can be no assurance that any agreement will result from such negotiations, if
a definitive merger agreement is reached on or prior to February 5, 1997, it
is Western Resources' present intention to terminate the KCPL Offer at such
time and to proceed with the KCPL Merger.     
   
  If an agreement with KCPL is not reached, Western Resources expects that it
will extend the KCPL Offer from time to time in its sole discretion until all
conditions thereto are satisfied, which Western Resources currently expects to
occur prior to the end of 1997. Western Resources' obligation to exchange
shares of Western Resources Common Stock for shares of KCPL Common Stock
pursuant to the KCPL Offer is subject to various terms and conditions set
forth in the KCPL Prospectus. Western Resources reserves the right, in its
sole discretion, at any time or from time to time to amend or terminate the
KCPL Offer in compliance with applicable law.     
 
                              RECENT DEVELOPMENTS
   
  On December 12, 1996, Western Resources and ONEOK announced that they had
entered into a proposed strategic alliance in which Western Resources will
contribute its regulated local natural gas distribution operations, MCMC, and
Westar Gas Marketing, and will become the largest shareholder of ONEOK. A
division of ONEOK, the Oklahoma Natural Gas Company, provides local natural
gas service to 75% of the state of Oklahoma. ONEOK also has interests in
natural gas marketing, processing and production.     
 
  In the transaction, which is expected to close in mid-1997, Western
Resources will receive 2,996,702 shares of ONEOK common stock ("ONEOK Common
Stock") and 19,317,584 shares of a new series of convertible preferred stock
of ONEOK ("ONEOK Preferred Stock"), representing 45% of the total equity of
ONEOK. The ONEOK Preferred Stock will pay an annual dividend of up to 1.5
times the ONEOK Common Stock dividend, with a minimum dividend of $1.80 per
share. The transaction is expected to be accretive to Western Resources in the
first full year.
   
  As a result of its alliance with Western Resources, ONEOK will become the
ninth largest gas distribution company in the United States, serving 1.4
million customers. The strategic alliance will also include a marketing
agreement under which Western Resources will provide electric energy products,
security products and other unregulated services to ONEOK's existing 735,000
customers. The transaction requires the approval of ONEOK's shareholders, the
Oklahoma Corporation Commission (the "OCC"), the KCC and the Commission.
Pursuant to the HSR Act, the transaction may not be consummated unless certain
information has been furnished to the Antitrust Division and the FTC and
certain waiting period requirements have been satisfied. Western Resources
shareholders will not vote on the transaction.     
   
  On December 31, 1996, Western Resources paid approximately $358 million,
subject to certain adjustments and assumed certain liabilities and
obligations, for all of the assets used in, related to or necessary for the
operation of the security installation, monitoring and service business
currently operated by Westinghouse Security, a subsidiary of Westinghouse. As
a result of the acquisition, Westar Security is now the third-largest
monitored security company in the United States with over 400,000 customers,
offices in many major U.S. markets and direct access to customers in 44
states.     
 
                          VOTING AND PROXY PROCEDURES
 
GENERAL
 
  Only persons entered in the register of members of ADT as holders of Shares
at the time of the ADT Special Meeting will be entitled to vote at such
meeting unless the ADT Board sets a record date for the ADT Special Meeting.
In the event the ADT Board sets a record date for the ADT Special Meeting,
only holders of Shares at the close of business on such record date will be
entitled to vote at the ADT Special Meeting. Each Share is
 
                                      24

entitled to one vote upon each matter presented at the ADT Special Meeting.
Holders of ADT preferred stock, if any, are not entitled to vote on any of the
Western Resources Proposals. Pursuant to Bye-Law 43 of the ADT Bye-Laws, at
any general meeting of ADT not less than two holders of Shares present either
in person or by proxy constitutes a quorum for the transaction of business.
Each of the Western Resources Proposals may be approved by the affirmative
vote of a majority of those Shares voted at the ADT Special Meeting. ADT
Shareholders do not have cumulative voting for directors.
 
  Pursuant to Bermuda law, only votes cast for a matter constitute affirmative
votes. Votes withheld or abstaining from voting are counted for quorum
purposes only.
 
  Any ADT Shareholder owning Shares held in the name of a brokerage firm, bank
or other institution should sign, date and return the GREEN proxy card to such
brokerage firm, bank or other institution in the envelope provided by that
firm. The accompanying GREEN proxy card will be voted in accordance with the
ADT Shareholder's instructions on such GREEN proxy card. In order to comply
with Bye-Law 48(1) of the ADT Bye-Laws, which requires that any person acting
as a proxy must be a shareholder of ADT, each of the representatives of
Western Resources named as a proxy on the accompanying proxy card will own at
least one Share at the time of the ADT Special Meeting.
 
OTHER PROPOSALS
 
  EXCEPT FOR THE WESTERN RESOURCES PROPOSALS AS SET FORTH ABOVE, WESTERN
RESOURCES IS NOT AWARE OF ANY PROPOSALS TO BE BROUGHT BEFORE THE ADT SPECIAL
MEETING. SHOULD OTHER PROPOSALS BE BROUGHT BEFORE THE ADT SPECIAL MEETING, THE
PERSONS NAMED ON THE GREEN PROXY CARD WILL ABSTAIN FROM VOTING ON SUCH
PROPOSALS UNLESS SUCH PROPOSALS ADVERSELY AFFECT THE INTERESTS OF WESTERN
RESOURCES AS DETERMINED BY WESTERN RESOURCES IN ITS SOLE DISCRETION, IN WHICH
EVENT SUCH PERSONS WILL VOTE ON SUCH PROPOSALS AT THEIR DISCRETION.
 
REVOCATION OF PROXIES
   
  An executed proxy may be revoked at any time prior to its exercise by
submitting another proxy with a later date, by voting in person at the ADT
Special Meeting or by sending a written, signed, dated revocation which
clearly identifies the proxy being revoked to the Chairman of the ADT Special
Meeting prior to the ADT Special Meeting or to the Secretary of ADT at the
registered office of ADT at Cedar House, 41 Cedar Avenue, Hamilton HM12,
Bermuda, so as to arrive before the ADT Special Meeting. Proxies may be
revoked prior to the ADT Special Meeting by facsimile transmission addressed
to the Chairman of the ADT Special Meeting at (  )   -  , or to the Secretary
of ADT at ( )   -  . A revocation may be in any written form validly signed by
the registered holder as long as it clearly states that the proxy previously
given is no longer effective.     
 
                              PROXY SOLICITATION
   
  Proxies for the ADT Special Meeting will be solicited by mail, telephone,
telegraph, telex, telecopier, facsimile and advertisement and in person.
Certain information about the directors and executive officers of Western
Resources and certain employees and other representatives of Western Resources
who may also assist MacKenzie Partners, Inc. ("MacKenzie") in soliciting
proxies is set forth in the attached Schedule A. Schedule B sets forth certain
information relating to Shares owned by Western Resources and its affiliates
and Western Resources' directors, executive officers, employees and other
representatives and certain transactions between any of them and ADT.     
 
  The entire expense of the Proxy Solicitation is being borne by Western
Resources. Western Resources may seek reimbursement for such expenses from
ADT, but does not expect that the question of such reimbursement will be
submitted to a vote of ADT Shareholders. Costs related to the Proxy
Solicitation include expenditures for
 
                                      25
<PAGE>
 
attorneys, accountants, financial advisors, proxy solicitors, public relations
advisors, printing, advertising, postage, litigation and related expenses and
filing fees and are expected to aggregate approximately $    million. Election
of the Western Resources Nominees and consummation of the Offer may, among
other things, (i) result in acceleration of credit facilities currently
available to ADT Operations, Inc., a subsidiary of ADT ("ADT Operations"),
(ii) enable the holders of certain debt instruments of ADT Operations to
require the repurchase of their securities, and (iii) accelerate the date on
which certain options outstanding under ADT's stock option plans become
exercisable. Although Western Resources and Westar Capital do not believe that
these events would materially and adversely impact the financial condition of
ADT, the actual impact of such events cannot be presently ascertained and will
depend, among other things, on interest rates and the future conditions in the
credit markets.
   
  Western Resources has retained MacKenzie to act as Information Agent in
connection with the Proxy Solicitation. The Information Agent may contact
holders of Shares by mail, telephone, telex, telegraph, facsimile and personal
interviews and may request brokers, dealers and other nominee shareholders to
forward Proxy Solicitation materials to beneficial owners of Shares. The
Information Agent will be paid a customary fee of [$   ] for such services,
plus reimbursement of out-of-pocket expenses, and Western Resources will
indemnify the Information Agent against certain liabilities and expenses in
connection with the Proxy Solicitation, including liabilities under federal
securities laws.     
 
  Salomon Brothers Inc ("Salomon"), Bear, Stearns & Co. Inc. ("Bear Stearns")
and Chase Securities Inc. ("Chase") are acting as Dealer Managers (the "Dealer
Managers") in connection with the Offer.
 
  Salomon is acting as financial advisor to Western Resources in connection
with its effort to acquire ADT, for which services, and for assistance
rendered by Salomon in connection with prior purchases of Shares by Westar
Capital, Western Resources has agreed to pay Salomon aggregate fees up to a
maximum of $5 million (a substantial portion of which is contingent upon the
consummation of an acquisition of 50% or more of the Shares of ADT or upon
consummation of the Amalgamation).
 
  Bear Stearns is acting as financial advisor to Western Resources in
connection with is effort to acquire ADT, for which services, and for
assistance rendered by Bear Stearns in connection with prior purchases of
Shares by Westar Capital, Western Resources has agreed to pay Bear Stearns
aggregate fees up to a maximum of $4.3 million (a substantial portion of which
is contingent upon the consummation of an acquisition of 50% or more of the
Shares of ADT or upon consummation of the Amalgamation).
 
  Chase is acting as financial advisor to Western Resources in connection with
its effort to acquire ADT, for which services Western Resources has agreed to
pay Chase aggregate fees up to a maximum of $1.5 million (a substantial
portion of which is contingent upon the consummation of an acquisition of 50%
or more of the Shares of ADT or upon consummation of the Amalgamation).
 
  In addition to the compensation set forth above, Western Resources has
agreed to reimburse the Dealer Managers for their reasonable travel and other
out-of-pocket expenses. Western Resources has also agreed to reimburse each of
the Financial Advisors for necessary and reasonable attorney's fees incurred
in connection with their engagement, and has agreed to indemnify each of the
Dealer Managers and certain related persons and entities against certain
liabilities and expenses in connection with the Dealer Managers' engagement,
including certain liabilities under the federal securities laws. In connection
with each of Salomon's, Bear Stearns' and Chase's engagement as Dealer
Manager, Western Resources anticipates that certain employees of Salomon, Bear
Stearns and Chase may communicate in person, by telephone or otherwise with a
limited number of institutions, brokers or other persons who are ADT
Shareholders for the purpose of assisting in the Proxy Solicitation. Neither
Salomon, Bear Stearns nor Chase will receive any fee for or in connection with
such solicitation activities by its employees apart from the fees it is
otherwise entitled to receive as described above.
 
  In addition to the fees to be received by each of Salomon, Bear Stearns and
Chase in connection with their engagement as Dealer Managers for the Offer,
Salomon, Bear Stearns and Chase have in the past rendered
 
                                      26
<PAGE>
 
various investment banking and financial advisory services for Western
Resources for which they have received customary compensation. In particular,
pursuant to a letter agreement dated September 5, 1995, as amended (the
"Salomon KCPL Letter Agreement"), Salomon is providing certain financial
advisory services to Western Resources in connection with the KCPL Offer.
Under the terms of the Salomon KCPL Letter Agreement, Western Resources has
agreed to pay Salomon for its financial advisory services (including services
as Dealer Manager) in connection with the KCPL Offer, a financial advisory fee
of (i) $400,000 upon execution of the Salomon KCPL Letter Agreement, (ii)
$500,000 upon public announcement of the KCPL Offer, and (iii) up to an
additional $6,000,000 (less amounts paid or payable described in (i) and (ii)
above) upon Western Resources' acquisition of more than 20% of the outstanding
KCPL Shares or upon the consummation of the KCPL Merger.
 
  Western Resources will not pay any fees or commissions to any broker or
dealer or other person (other than the Information Agent and the Dealer
Managers) for soliciting proxies for the ADT Special Meeting. Brokers,
dealers, commercial banks and trust companies will be reimbursed by Western
Resources for customary mailing and handling expenses incurred by them in
forwarding material to their customers.
 
                          ABSENCE OF APPRAISAL RIGHTS
 
  ADT Shareholders do not have appraisal rights with respect to the Offer.
   
  However, pursuant to Section 106(6) of the Companies Act, a registered
holder of Shares who does not vote in favor of the Amalgamation, if it is
proposed and submitted to a vote of ADT Shareholders, and who is not satisfied
that he or she has been offered fair value for his or her Shares, may, within
one month of the giving of the notice of the general meeting of ADT
Shareholders, apply to the Supreme Court of Bermuda (the "Bermuda Supreme
Court") to have the fair value of such dissenting ADT Shareholder's Shares
appraised by the Bermuda Supreme Court. Within one month of the Bermuda
Supreme Court appraising the fair value of any Shares, Western Resources shall
be entitled either to pay to the dissenting ADT Shareholder an amount equal to
the value of his or her Shares as appraised by the Bermuda Supreme Court or to
terminate the Amalgamation if the agreement with respect thereto so provides.
       
  A beneficial owner of Shares who is not the registered holder may not assert
appraisal rights. If the stock is owned in a fiduciary capacity, such as by a
trustee, guardian or custodian, or by a nominee, the notice asserting
appraisal rights must be executed by the fiduciary or nominee as the
registered holder of the Shares. If the Shares are owned of record by more
than one person, as in a joint tenancy or tenancy in common, the notice must
be executed by all joint owners. An authorized agent, including an agent for
two or more joint owners, may execute the notice for a registered shareholder;
however, the agent must identify the registered holder, disclose the fact
that, in executing the notice, he is acting as agent for the registered holder
and provide evidence of his authority.     
   
  The right of a dissenting shareholder to be paid the fair value of his or
her Shares shall cease if the shareholder fails to comply with the procedures
set forth in Section 106(6) of the Companies Act, or if the Amalgamation is
abandoned for any reason.     
 
  Western Resources presently intends to condition the Amalgamation upon,
among other things, holders of not more than 5% of the outstanding Shares
having perfected appraisal rights with respect to the Amalgamation.
   
  The foregoing does not purport to be a complete statement of the procedures
to be followed by ADT Shareholders desiring to exercise dissenters' rights
and, in view of the fact that exercise of such rights requires adherence to
the relevant provisions of the Companies Act, shareholders who desire to
exercise appraisal rights are advised to review with care all applicable
provisions of law and to obtain legal counsel in Bermuda concerning proper
compliance with applicable provisions of the Companies Act. ADT Shareholders
are urged to, and should, read Section 106 of the Companies Act, a copy of
which is included herein as Schedule G.

                           ADT AND KCPL INFORMATION
   
  While Western Resources has included information concerning ADT and KCPL
insofar as it is known or reasonably available to Western Resources, neither
ADT nor KCPL is affiliated with Western Resources and neither ADT nor KCPL has
to date permitted access by Western Resources to ADT's or KCPL's books and
records for the purpose of preparing this Proxy Statement. Therefore,
information concerning ADT and KCPL which has not been made public was not
available to Western Resources for the purpose of preparing this Proxy
Statement. Although Western Resources has no knowledge that would indicate
that statements relating to ADT or KCPL contained or incorporated by reference
in this Proxy Statement in reliance upon publicly available information are
inaccurate or incomplete, Western Resources was not involved in the
preparation of such information and statements and, for the foregoing reasons,
is not in a position to verify any such information or statements.

                BYE-LAW 104. TAKE-OVER OFFERS FOR THE COMPANY.
 
  (1) (A) Where any person is or becomes interested, whether as a result of
          transactions over a period of time or not, in shares in the capital
          of the Company in circumstances in which he would be obliged to make
          or extend an offer or offers to shareholders or holders of other
          securities or rights referred to in paragraph (4) below of the
          Company under the Rules for the time being of the City Code on Take-
          overs and Mergers of the United Kingdom of Great Britain and
          Northern Ireland (the "City Code", which expression shall include
          any revision or modification thereof) issued by the Panel on Take-
          overs and Mergers ("the Panel", which expression shall include any
          body which succeeds to the functions of the said Panel) if the
          Company was a company incorporated in the United Kingdom of Great
          Britain and Northern Ireland to which the City Code applied, the
          Directors may serve upon that person a notice requiring him to make
          or extend an offer or offers in writing in accordance with the
          requirements of the City Code in all respects as if the City Code
          did apply to the Company but so that references in the City Code to
          the Panel shall be construed, for the purposes of this Bye-Law, as
          if they were references to the Board of Directors of the Company.
 
(B)      Where any person has acquired, is in the process of acquiring, or
         appears to the Directors likely to acquire an interest in shares in
         the capital of the Company in circumstances in which he would be
         subject to the Rules Governing Substantial Acquisitions of Shares
         (the "SARs", which expression shall include any revision or
         modification thereof issued by the Panel, if the Company was a
         company incorporated in the United Kingdom of Great Britain and
         Northern Ireland to which the SARs applied, the Directors may serve
         upon that person a notice requiring him to comply with the provisions
         of the SARs in relation to any acquisition made (after the date of
         adoption of this paragraph (1)(B)) or proposed to be made by him and
         if that person has made (after the date of adoption of this paragraph
         (1)(B)) or subsequently makes any acquisition in contravention of the
         provisions of the SARs such a notice or a further notice issued by
         the Directors may require that person to dispose or to procure the
         disposal by any person with whom he has acted in concert of any
         interest in shares so acquired within twenty-eight days of the date
         of such notice.
 
(C)      If a notice served under paragraph (1)(B) requiring a disposal of
         shares is not complied with in accordance with its terms and has not
         been withdrawn, the Directors may, so far as they are able, dispose
         of the shares to which such notice relates at the best price
         reasonably obtainable in all the circumstances in which case they
         shall give written notice of such disposal to the person or persons
         on whom such notice was served. Except as hereinafter provided such a
         disposal shall be completed as soon as reasonably practicable after
         the giving of a notice under this paragraph (1)(C) as may in the
         opinion of the Directors be consistent with obtaining the best price
         reasonably obtainable and in any event within thirty days of expiry
         of such notice provided that a disposal under this paragraph (1)(C)
         shall be suspended during the period when dealings by the Directors
         in the Company's shares are not permitted either by law or by the
         regulations of any stock exchange upon which those shares of the
         Company which are to be disposed of are listed, but any disposal
         under this paragraph which is suspended as aforesaid shall be
         completed within thirty days after expiry of the period of such
         suspension and provided further that neither the Company nor the
         Directors shall be liable to any holder or any person having an
         interest in any share or other person for failing to obtain the best
         price so long as the Directors act in good faith within the period
         specified above.
 
(D)      For the purpose of effecting any disposal under paragraph (1)(C)
         above, the Directors may authorise in writing any officer or employee
         of the Company to execute any necessary transfer on behalf of any
         holder and may issue a new certificate to the purchaser. The net
         proceeds of such disposal shall be received by the Company, whose
         receipt shall be a good discharge for the purchase money, and shall
         be paid (without any interest being payable thereon) to the former
         holder upon surrender by him of the certificate in respect of the
         shares sold and formerly held by him.

(E)      The provisions of these Bye-Laws relating to the protection of
         purchasers of shares sold under a lien or upon forfeiture shall apply
         mutatis mutandis to disposals under this Bye-Law.
 
  (2) Any notice served under paragraph (1) above may also require the person
      on whom it is served to execute an undertaking under seal in favour of
      the Directors (as trustees for all the holders of shares in the capital
      of the Company) and in a form satisfactory to the Directors to observe
      and perform the rules and requirements of the City Code or the SARs as
      the case may be as if the same were applicable to the Company and in the
      manner prescribed in paragraph (1) above.
 
  (3) Where any person is interested, whether as a result of a series of
      transactions over a period of time or not, in Common Shares which (taken
      together with shares held or acquired by persons acting in concert with
      him) represent 30 per cent. or more of all the Common Shares for the
      time being in issue and the Directors determine that it is not expedient
      to serve a notice under paragraph (1)(A) above or if any person upon
      whom such a notice is served fails within thirty days to comply with the
      same, the Directors may serve upon that person a notice requiring him to
      make an offer in writing (the "Offer"), within 30 days of the date of
      such notice on the basis set out in the following paragraphs, to the
      holders of every class of share capital of the Company (whether voting
      or non-voting) to purchase all such shares for cash on terms that
      payment in full therefor will be made within 21 days of the Offer
      becoming or being declared unconditional in all respects.
 
  (4) Where the Directors serve a notice upon any person in accordance with
    paragraph (3) above, they may also include in that notice a requirement
    that such person shall make an appropriate offer or proposal in writing
    to the holders of every class of securities convertible into, or of
    rights to subscribe for, share capital of the Company (whether such share
    capital is voting or non-voting). Such appropriate offer or proposal is
    referred to in this Bye-Law as a "Convertible Offer". The Convertible
    Offer shall be made at the same time as the Offer. The terms of the
    Convertible Offer shall be such terms as the Directors, in their absolute
    discretion, consider to be fair and reasonable having regard to the terms
    of the Offer and the Directors shall notify such terms to the person
    specified in paragraph (3) above (the "Offeror"). The Convertible Offer
    shall be conditional only upon the Offer becoming or being declared
    unconditional in all respects.
 
  (5) In addition to the Offeror, the Directors may require, in their
    absolute discretion, each of the principal members of a group of persons
    acting in concert with him and who appear to be interested in any shares
    in, or convertible securities of, the Company to make the Offer and/or
    the Convertible Offer. For the purposes of this Bye-Law, persons shall be
    deemed to be acting in concert if, pursuant to an agreement or
    understanding (whether formal or informal) they actively co-operate in
    acquiring or seeking to acquire shares in, or convertible securities of,
    the Company.
 
  (6) Unless the Directors otherwise agree, an offer made under paragraphs
    (3), (4) or (5) of this Bye-Law must, in respect of each class of share
    capital or convertible securities involved, be in cash or be accompanied
    by a cash alternative offer at not less than the highest price paid by
    the Offeror or any person acting in concert with it for shares or
    convertible securities of that class within the preceding 12 months. If
    such price cannot be ascertained by the Directors or if such shares or
    convertible securities have been acquired other than for cash pursuant to
    a bargain made on any recognised stock exchange or if the Directors
    consider that such highest price is, for any reason, inappropriate,
    unfair or unreasonable having regard to the size and timing of the
    relevant purchases, the relationship (if any) between the seller and
    purchaser of such shares or convertible securities or the number of
    shares or convertible securities purchased in the preceding 12 months,
    the Directors may, in any such case, fix the price at which the Offer,
    the Convertible Offer or the cash alternative offer is to be made. The
    cash Offer, the cash Convertible Offer or the cash alternative offer
    must, in each case, remain open for not less than 14 days after the date
    on which the Offer or the Convertible Offer, as the case may be, has
    become or is declared to be unconditional as to acceptances.
 
                                      E-2

  (7) Any person who makes or is about to make or who is or can be required
    to make an offer under this Bye-Law or who has made such an offer which
    has lapsed, shall observe and shall procure that any persons acting in
    concert with him shall observe the rules and requirements of the City
    Code both in letter and in spirit prior to, during the pursuit of and, if
    applicable, after the failure of such an offer.
 
  (8) For the purposes of this Bye-Law, any questions or disputes arising out
    of the grant of consent by the Directors, the comparability of offers,
    the terms of offers, any question as to whether any person shall be
    regarded as acting in concert with another, any question regarding the
    interpretation or application of the City Code and the meaning of any
    terms or phrases used in this Bye-Law or the City Code shall be
    determined by the Directors in their absolute discretion.

        (c) for the purpose of this sub-paragraph (B) a person shall be
            treated as appearing to be interested in any shares if (after

      Provided that:--

            (2) of this Bye-Law which fulfils sub-sub-paragraphs (i) and

            with the service of such a notice, served by the Company with a
            notice under Bye-Law 104; and

            respects in accordance with its terms.
 
    (D) in respect of any shares in relation to which he and any person

         Company knows or has reasonable cause to believe to be interested in
         shares in the Company to indicate whether or not it is the case and,
         where that person holds any interest in any such shares, to give such
         further information as may be required in accordance with sub-
         paragraph (B) below.
 
    (B) Any such notice may require the person to whom it is addressed to
       give particulars of his own present interests in shares in the
       Company.
 
    (C)
      The particulars referred to above include particulars of the identity
      of persons interested in the shares in question and of whether
      persons interested in the same shares are parties to any agreement or
      arrangement relating to the exercise of any of the rights conferred
      by the holding of the shares.
 
    (D)
      A notice under this Bye-Law shall require any information given in
      response to the notice to be given in writing within such reasonable
      time as the Directors may determine and is specified in the notice.
 
    (E)
      For the purposes of this Bye-Law, a person who is interested in a
      right to subscribe for or convert into shares in the Company shall be
      deemed to be interested in shares in the Company and references to
      interests in shares shall include any interest whatsoever in such
      shares including, without limitation, a right to control directly or
      indirectly the exercise of any right conferred by the holding of
      shares alone or in conjunction with a person deemed to be acting in
      concert for the purposes of Bye-Law 104 and the interest of any
      person shall be deemed to include the interest of any other person
      deemed to be acting in concert as aforesaid.
 
    (F)
      A notice which has taken effect under this Bye-Law shall remain in
      effect in accordance with its terms following a transfer of the
      shares to which it relates unless and until the Directors determine
      otherwise and notify the registered holder accordingly.
 
    (G)
      The right to receive payments of income or capital which become due
      or payable in respect of any share during a period of
      disqualification applicable to such share under this Bye-Law shall be

      Member for late payment or non-payment and the Company may retain
      such sums for its own use and benefit during such period of
      suspension and the holders of such shares may, in the discretion of
      the Directors, be excluded from participation in any further issue of
      shares by reference to an existing holding of shares at a point in
      time during such period of suspension. No trust shall be created in
      respect of any such debt, no interest shall be payable in respect of
      the same and the Company shall not be required to account for any
      money earned on such amount, which may be employed in the business of
      the Company or invested in such investments as the Directors may from
      time to time think fit.
 
  (3) (A) Where any person whether alone or in circumstances where for the
         purposes of Bye-Law 104 he is acting in concert with other persons
         acquires or has acquired interests in shares which (including the
         interests of persons with whom he is acting in concert as aforesaid)
         amount to three per cent. or more of the issued share capital of any
         class of the Company he shall within two days following the date on
         which he became aware (or ought reasonably to have become aware) of
         the acquisition of such an interest notify the Company of the
         existence of such interest and shall in making such notification to
         the Company also supply the particulars referred to in sub-paragraphs
         (2)(B) and (2)(C) above and so long as his interest as aforesaid
         amounts to three per cent. or more of the issued share capital of any
         class of the Company he shall notify the Company of any change in his
         interests (including the interests of persons with whom he is acting
         in concert as aforesaid) amounting to one per cent. or more of the
         issued share capital of any class of the Company within two days
         following the date on which he became aware (or ought reasonably to
         have become aware) of such change.
 
    (B)
      If any person has failed to make a notification in accordance with
      sub-paragraph (3)(A) above (notwithstanding that such notification
      has been made after the said period of two days) the Directors may
      serve a notice on such person stating that the registered holder of
      the shares in which that person is interested shall not be entitled
      to vote or otherwise exercise the rights referred to in this Bye-Law
      in respect of any shares or a number of shares specified in the
      notice held by that registered holder during the one hundred and
      eighty days following the service of such notice provided that the
      registered holder of such shares has previously been, or is
      simultaneously with the service of such a notice, served with a
      notice under this sub-paragraph.
 
    (C)
      If the Directors resolve that they have reasonable cause to believe
      that a person is or may be interested in shares of the Company or
      that any such shares are or may be shares in which any person is
      interested and that they have made reasonable enquiries to establish
      whether a person is so interested, or whether they are such shares,
      as the case may be, such person shall for the purposes of this Bye-
      Law be deemed to be interested in shares or, as the case may be, such
      shares shall be deemed to be shares in which such person is
      interested, from the date of such resolution until any such time as
      the Directors resolve otherwise.
 
    (D)
      Any belief, resolution or decision of the Directors which is held or
      made in pursuance or purported pursuance of any of the provisions of
      this Bye-Law shall be conclusive, final and binding on all persons
      concerned, and the validity of any act or thing which is done or
      caused to be done by the Directors in pursuance or purported
      pursuance of any of such provisions shall not be capable of being
      impeached by anyone on the ground that there was not any basis or

                               THE COMPANIES ACT
 
                       SECTION 106. SHAREHOLDER APPROVAL
 
SHAREHOLDER APPROVAL
 
  (1) The directors of each amalgamating company shall submit the amalgamation
for approval to a meeting of the holders of shares of the amalgamating company
of which they are directors and, subject to subsection (4), to the holders of
each class of such shares.
 
  (2) A notice of a meeting of shareholders complying with section 75 shall be
sent in accordance with that section to each shareholder of each amalgamating
company, and shall--
 
    (a) include or be accompanied by a copy or summary of the amalgamation
  agreement; and
 
    (b) subject to subsection 2A, state--
 
      (i) the fair value of the shares as determined by each amalgamating
    company; and
 
      (ii) that a dissenting shareholder is entitled to be paid the fair
    value of his shares.
 
  (2A) Notwithstanding subsection 2(b)(ii), failure to state the matter
referred to in that subsection does not invalidate an amalgamation.
 
  (3) Each share of an amalgamating company carries the right to vote in
respect of an amalgamation whether or not it otherwise carries the right to
vote.
 
  (4) The holders of shares of a class of shares of an amalgamating company
are entitled to vote separately as a class in respect of an amalgamation if
the amalgamation agreement contains a provision which would constitute a
variation of the rights attaching to any such class of shares for the purposes
of section 47.
 
  (4A) The provisions of the bye-laws of the company relating to the holding
of general meetings shall apply to general meetings and class meetings
required by this section provided that, unless the bye-laws otherwise provide,
the resolution of the shareholders or class must be approved by a majority
vote of three-fourths of those voting at such meeting and the quorum necessary
for such meeting shall be two persons at least holding or representing by
proxy more than one-third of the issued shares of the company or the class, as
the case may be, and that any holder of shares present in person or by proxy
may demand a poll.
 
  (5) An amalgamation agreement shall be deemed to have been adopted when it
has been approved by the shareholders as provided in this section.
 
  (6) Any shareholder who did not vote in favour of the amalgamation and who
is not satisfied that he has been offered fair value for his shares may within
one month of the giving of the notice referred to in subsection (2) apply to
the Court to appraise the fair value of his shares.
 
  (6A) Subject to subsection (6B), within one month of the Court appraising
the fair value of any shares under subsection (6) the company shall be
entitled either--
 
    (a) to pay to the dissenting shareholder an amount equal to the value of
  his shares as appraised by the Court; or
 
    (b) to terminate the amalgamation in accordance with subsection (7).
 
  (6B) Where the Court has appraised any shares under subsection (6) and the
amalgamation has proceeded prior to the appraisal then, within one month of
the Court appraising the value of the shares, if the amount paid to the
dissenting shareholder for his shares is less than that appraised by the Court
the amalgamated company shall pay to such shareholder the difference between
the amount paid to him and the value appraised by the Court.
 
  (6C) No appeal shall lie from an appraisal by the Court under this section.
 
  (6D) The costs of any application to the Court under this section shall be
in the discretion of the Court.
 
  (7) An amalgamation agreement may provide that at any time before the issue
of a certificate of amalgamation the agreement may be terminated by the
directors of an amalgamating company, notwithstanding approval of the
agreement by the shareholders of all or any of the amalgamating companies.
