TO THE HOLDERS OF COMMON STOCK OF
  ELECTROSTAR, INC.
 
                                  INTRODUCTION
 
    T3 Acquisition Corp., a Florida corporation (the "Purchaser") and a wholly
owned subsidiary of Tyco International Ltd., a Massachusetts corporation
("Tyco"), hereby offers to purchase all outstanding shares of common stock, par
value $.01 per share (the "Shares"), of ElectroStar, Inc., a Florida corporation
(the "Company"), at $14.00 per Share, net to the seller in cash, upon the terms
and subject to the conditions set forth in this Offer to Purchase and in the
related Letter of Transmittal (which together constitute the "Offer").
 
    Tendering shareholders will not be obligated to pay brokerage fees or
commissions or, subject to Instruction 6 of the Letter of Transmittal, stock
transfer taxes on the purchase of Shares by the Purchaser pursuant to the Offer.
However, any tendering shareholder or other payee who fails to complete and sign
the Substitute Form W-9 that is included in the Letter of Transmittal may be
subject to a required backup federal income tax withholding of 31% of the gross
proceeds payable to such shareholder or other payee pursuant to the Offer. See
Section 2. The Purchaser will pay all charges and expenses of MacKenzie
Partners, Inc., as Information Agent (the "Information Agent"), and ChaseMellon
Shareholder Services, L.L.C., as Depositary (the "Depositary"), incurred in
connection with the Offer. See Section 17.
 
    THE OFFER IS CONDITIONED UPON, AMONG OTHER THINGS, THERE BEING VALIDLY
TENDERED AND NOT WITHDRAWN PRIOR TO THE EXPIRATION OF THE OFFER A NUMBER OF
SHARES REPRESENTING AT LEAST A MAJORITY OF THE TOTAL NUMBER OF OUTSTANDING
SHARES OF THE COMPANY ON A FULLY DILUTED BASIS AS OF THE DATE THE SHARES ARE
ACCEPTED FOR PAYMENT PURSUANT TO THE OFFER. BENEFICIAL OWNERS OF APPROXIMATELY
61% (57% ON A FULLY DILUTED BASIS) OF THE TOTAL NUMBER OF OUTSTANDING SHARES OF
THE COMPANY HAVE AGREED TO TENDER ALL OF THEIR SHARES PURSUANT TO THE OFFER. THE
OFFER IS ALSO SUBJECT TO CERTAIN OTHER TERMS AND CONDITIONS SET FORTH IN SECTION
15.
 
    The Offer is being made pursuant to an Agreement and Plan of Merger, dated
as of November 27, 1996 (the "Merger Agreement"), among Tyco, the Purchaser and
the Company. The Merger Agreement provides, among other things, that upon the
terms and subject to the conditions therein, as soon as practicable after the
consummation of the Offer, the Purchaser will be merged with and into the
Company (the "Merger"), with the Company being the corporation surviving the
Merger (the "Surviving Corporation"). At the effective time of the Merger (the
"Effective Time"), each outstanding Share (other than Shares owned by the
Company, any subsidiary of the Company, Tyco, the Purchaser, any other
subsidiary of Tyco or by shareholders, if any, who are entitled to and who
properly exercise dissenters' rights under the Florida Business Corporation Act
(the "FBCA")), will be converted into and represent the right to receive $14.00
in cash or any higher price that may be paid per Share in the Offer (the "Merger
Consideration"), without interest. See Section 13.
 
    THE BOARD OF DIRECTORS OF THE COMPANY HAS DETERMINED THAT THE OFFER AND THE
MERGER ARE FAIR TO, AND IN THE BEST INTERESTS OF, THE COMPANY AND ITS
SHAREHOLDERS, HAS APPROVED THE MERGER AGREEMENT, THE OFFER AND THE MERGER, AND
RECOMMENDS THAT THE COMPANY'S SHAREHOLDERS ACCEPT THE OFFER AND TENDER THEIR
SHARES PURSUANT TO THE OFFER.
 
    Alex. Brown & Sons Incorporated ("Alex. Brown"), the Company's financial
advisor, has delivered to the Company's Board of Directors its written opinion
that the consideration to be received by the shareholders of the Company
pursuant to the Offer and the Merger is fair to such shareholders from a
financial point of view. A copy of such opinion is contained in the Company's
Solicitation/Recommendation Statement on Schedule 14D-9 which is being
distributed to the Company's shareholders herewith.
 
    The Merger Agreement provides that, promptly upon the purchase of Shares
pursuant to the Offer, Tyco will be entitled to designate for election to the
Board of Directors of the Company a number of
 
                                       1
<PAGE>
directors (rounded up to the next whole number) equal to that number of
directors which equals the product of (i) the total number of directors on the
Board of Directors and (ii) the percentage that the aggregate number of Shares
purchased by the Purchaser in the Offer bears to the total number of Shares
outstanding. The Company has agreed, upon the request of Tyco, to increase the
size of the Board of Directors of the Company and/or use its reasonable best
efforts to secure the resignations of such number of directors as is necessary
to enable Tyco's designees to be elected to the Board of Directors and to cause
Tyco's designees to be so elected.
 
    The Company has informed the Purchaser that as of December 1, 1996 there
were 7,537,097 Shares outstanding (including 620,737 Shares issuable upon
conversion of the Company's Class B Common Stock, par value $.01 per share), and
497,129 Shares reserved for issuance pursuant to outstanding options. As of the
date hereof, neither the Purchaser, Tyco nor any of their affiliates
beneficially owns any Shares (other than Shares that they may be deemed to
beneficially own by virtue of the Shareholder Agreement described herein). Based
on such number of outstanding Shares and options, if the Purchaser acquires at
least 4,017,114 Shares in the Offer, it will own a majority of the outstanding
Shares on a fully diluted basis. In such event the Purchaser would have
sufficient voting power to approve the Merger without the affirmative vote of
any other shareholder. Beneficial owners of approximately 61% (57% on a fully
diluted basis) of the total number of outstanding Shares of the Company have
agreed to tender all of their Shares pursuant to the Offer. If the Purchaser
acquires 80% or more of the outstanding Shares in the Offer, the Purchaser would
be able to effect the Merger pursuant to the short form merger provisions of the
FBCA, without the action of any other shareholder of the Company.
 
    THIS OFFER TO PURCHASE AND THE RELATED LETTER OF TRANSMITTAL CONTAIN
IMPORTANT INFORMATION AND SHOULD BE READ IN THEIR ENTIRETY BEFORE ANY DECISION
IS MADE WITH RESPECT TO THE OFFER.
 
                                       2

                                THE TENDER OFFER
 
    1.  TERMS OF THE OFFER; EXTENSION OF TENDER PERIOD; TERMINATION;
AMENDMENTS.  Upon the terms and subject to the conditions of the Offer
(including, if the Offer is extended or amended, the terms and conditions of any
such extension or amendment), the Purchaser will accept for payment and pay for
all Shares which are validly tendered on or prior to the Expiration Date (as
hereinafter defined) and not theretofore withdrawn as permitted by Section 3.
The term "Expiration Date" means 12:00 Midnight, New York City time, on Friday,
January 3, 1997, unless and until the Purchaser (subject to the terms and
conditions of the Merger Agreement) shall have extended the period of time for
which the Offer is open, in which event the term "Expiration Date" shall mean
the latest time and date at which the Offer, as so extended by the Purchaser,
shall expire.
 
    The Offer is conditioned upon, among other things, the satisfaction of the
Minimum Condition (as defined in Section 15). The Purchaser reserves the right
(but shall not be obligated) to waive or reduce the Minimum Condition or to
waive any or all of the other conditions of the Offer. If, by 12:00 Midnight,
New York City time, on Friday, January 3, 1997, or any subsequent Expiration
Date, any or all of such conditions have not been satisfied or waived, subject
to the provisions of the Merger Agreement, the Purchaser may elect to (i)
terminate the Offer and return all tendered Shares to tendering shareholders,
(ii) waive all of the unsatisfied conditions and, subject to any required
extension, purchase all Shares validly tendered by the Expiration Date and not
withdrawn, (iii) extend the Offer and, subject to the right of shareholders to
withdraw Shares until the Expiration Date, retain the Shares that have been
tendered until the expiration of the Offer as extended, or (iv) delay acceptance
for payment of, or payment for, Shares, subject to complying with applicable
law, until the satisfaction or waiver of the conditions of the Offer. Under the
terms of the Merger Agreement, the Purchaser may not (except as described in the
next sentence), without the prior written consent of the Company, waive or amend
the Minimum Condition, reduce the number of Shares subject to the Offer, reduce
the price per Share to be paid pursuant to the Offer, extend the Offer if all of
the conditions to the Offer are satisfied or waived, change the form of
consideration payable in the Offer, or add, modify or amend any condition of the
Offer in any manner that would adversely affect the shareholders of the Company.
Notwithstanding the foregoing, the Purchaser may, without the consent of the
Company, extend the Offer (i) if, at the then scheduled Expiration Date of the
Offer, any of the conditions to the Purchaser's obligation to accept for payment
and pay for Shares shall not have been satisfied or waived until such time as
such conditions are satisfied or waived, (ii) for any period required by any
rule, regulation, interpretation or position of the Securities and Exchange
Commission (the "Commission") or the Commission staff applicable to the Offer or
(iii) for an aggregate period of not more than 10 business days (for all such
extensions) beyond the latest Expiration Date that would be permitted under
clause (i) or (ii) of this sentence if all of the conditions to the Offer are
satisfied or waived but the number of Shares tendered is less than 80% of the
then outstanding number of Shares.
 
    Subject to the applicable regulations of the Commission, the Purchaser also
expressly reserves the right (subject to the provisions of the Merger
Agreement), in its sole discretion, at any time or from time to time, to (i)
delay acceptance for payment of or, regardless of whether such Shares were
theretofore accepted for payment, payment for any Shares, (ii) terminate the
Offer (whether or not any Shares have theretofore been accepted for payment) if
any of the conditions referred to in Section 15 have not been satisfied or upon
the occurrence of any of the events specified in Section 15, and (iii) waive any
condition or otherwise amend the Offer in any respect, in each case by giving
oral or written notice of such delay, termination, waiver or amendment to the
Depositary and by making a public announcement thereof. If the Purchaser accepts
for payment any Shares pursuant to the terms of the Offer, it will accept for
payment all Shares validly tendered prior to the Expiration Date and not
withdrawn and, subject to clause (i) above, will promptly pay for all Shares so
accepted for payment. The Purchaser acknowledges that its reservation of the
right to delay payment for Shares that it has accepted for payment is limited by
(a) Rule 14e-l(c) under the Securities Exchange Act of 1934, as amended (the
"Exchange Act"), which requires the Purchaser to pay the consideration offered
or return the Shares tendered promptly after the termination or
 
                                       3
<PAGE>
withdrawal of the Offer, and (b) the requirement that the Purchaser may not
delay acceptance for payment of, or payment for, any Shares upon the occurrence
of any of the events specified in Section 15 without extending the period of
time during which the Offer is open.
 
    The rights reserved by the Purchaser in the preceding paragraph are in
addition to the Purchaser's rights pursuant to Section 15. Any extension, delay,
termination or amendment of the Offer will be followed as promptly as
practicable by public announcement thereof, such announcement in the case of an
extension to be issued no later than 9:00 a.m., New York City time, on the next
business day after the previously scheduled Expiration Date, in accordance with
the public announcement requirements of Rule 14e-1(d) under the Exchange Act.
Subject to applicable law (including Rules 14d-4(c) and 14d-6(d) under the
Exchange Act, which require that any material change in the information
published, sent or given to shareholders in connection with the Offer be
promptly disseminated to shareholders in a manner reasonably designed to inform
shareholders of such change) and without limiting the manner in which the
Purchaser may choose to make any public announcement, the Purchaser shall have
no obligation to publish, advertise or otherwise communicate any such public
announcement other than by making a release to the Dow Jones News Service.
 
    If the Purchaser makes a material change in the terms of the Offer or the
information concerning the Offer, or if it waives a material condition of the
Offer (including the Minimum Condition), the Purchaser will disseminate
additional tender offer materials (including by public announcement as set forth
above) and extend the Offer to the extent required by Rules 14d-4(c), 14d-6(d)
and 14e-1 under the Exchange Act. The minimum period during which an offer must
remain open following material changes in the terms of the Offer, other than a
change in price, percentage of securities sought or inclusion of or change to a
dealer's soliciting fee, will depend upon the facts and circumstances, including
the materiality, of the changes. In the Commission's view, an offer should
remain open for a minimum of five business days from the date the material
change is first published, sent or given to shareholders, and, if material
changes are made with respect to information that approaches the significance of
price and share levels, a minimum of ten business days may be required to allow
for adequate dissemination and investor response. With respect to a change in
price or, subject to certain limitations, a change in the percentage of
securities sought or inclusion of or change to a dealer's soliciting fee, a
minimum ten business day period from the date of such change is generally
required to allow for adequate dissemination to shareholders. Accordingly, if,
prior to the Expiration Date, the Purchaser decreases the number of Shares being
sought or increases or decreases the consideration offered pursuant to the
Offer, and if the Offer is scheduled to expire at any time earlier than the
period ending on the tenth business day from the date that notice of such
increase or decrease is first published, sent or given to holders of Shares, the
Offer will be extended at least until the expiration of such ten business day
period. For purposes of the Offer, a "business day" means any day other than a
Saturday, Sunday or a federal holiday and consists of the time period from 12:01
a.m. through 12:00 midnight, New York City time.
 
    The Company has provided or will provide the Purchaser with the Company's
shareholder list and security position listings for the purpose of disseminating
the Offer to holders of Shares. This Offer to Purchase, the related Letter of
Transmittal and other relevant materials will be mailed to registered holders of
Shares and will be furnished to brokers, dealers, commercial banks, trust
companies and similar persons whose names, or the names of whose nominees,
appear on the shareholder list or, if applicable, who are listed as participants
in a clearing agency's security position listing, for subsequent transmittal to
beneficial owners of Shares.
 
    2.  PROCEDURE FOR TENDERING SHARES.  Except as set forth below, in order for
Shares to be validly tendered pursuant to the Offer, the Letter of Transmittal
(or a facsimile thereof), properly completed and duly executed, together with
any required signature guarantees, or an Agent's Message (as hereinafter
defined) in connection with a book-entry transfer of Shares, and any other
documents required by the Letter of Transmittal, must be received by the
Depositary at one of its addresses set forth on the back cover of this Offer to
Purchase on or prior to the Expiration Date, and either (i) certificates
representing
 
                                       4
<PAGE>
tendered Shares must be received by the Depositary, or such Shares must be
tendered pursuant to the procedure for book-entry transfer set forth below (and
confirmation of receipt of such delivery must be received by the Depositary), in
each case on or prior to the Expiration Date, or (ii) the guaranteed delivery
procedures set forth below must be complied with. No alternative, conditional or
contingent tenders will be accepted.
 
    SIGNATURE GUARANTEES.  No signature guarantee is required on the Letter of
Transmittal (i) if such Letter of Transmittal is signed by the registered holder
of the Shares tendered therewith, unless such holder has completed either the
box entitled "Special Delivery Instructions" or the box entitled "Special
Payment Instructions" in the Letter of Transmittal, or (ii) if Shares are
tendered for the account of a firm that is a member in good standing of the
Security Transfer Agent's Medallion Program, the New York Stock Exchange
Medallion Signature Program or the Stock Exchange Medallion Program (each being
hereinafter referred to as an "Eligible Institution"). See Instruction 1 of the
Letter of Transmittal.
 
    If a certificate representing Shares is registered in the name of a person
other than the signer of the Letter of Transmittal (or a facsimile thereof), or
if payment is to be made, or Shares not accepted for payment or not tendered are
to be returned to a person other than the registered holder, the certificate
must be endorsed or accompanied by an appropriate stock power, in either case
signed exactly as the name(s) of the registered holder(s) appears on the
certificate, with the signature(s) on the certificate or stock power guaranteed
by an Eligible Institution. If the Letter of Transmittal or stock powers are
signed or any certificate is endorsed by trustees, executors, administrators,
guardians, attorneys-in-fact, officers of corporations or others acting in a
fiduciary or representative capacity, such persons should so indicate when
signing and, unless waived by the Purchaser, proper evidence satisfactory to the
Purchaser of their authority so to act must be submitted. See Instruction 5 of
the Letter of Transmittal.
 
    BOOK-ENTRY TRANSFER.  The Depositary will establish accounts with respect to
the Shares at The Depository Trust Company and the Philadelphia Depository Trust
Company (individually, a "Book-Entry Transfer Facility" and, collectively, the
"Book-Entry Transfer Facilities") for purposes of the Offer within two business
days after the date of this Offer to Purchase, and any financial institution
that is a participant in any of the Book-Entry Transfer Facilities' systems may
make book-entry delivery of the Shares by causing any Book-Entry Transfer
Facility to transfer such Shares into the Depositary's account in accordance
with such Book-Entry Transfer Facility's procedure for such transfer. However,
although delivery of Shares may be effected through book-entry transfer at any
Book-Entry Transfer Facility, a properly completed and duly executed Letter of
Transmittal (or facsimile thereof), with any required signature guarantees, or
an Agent's Message and any other required documents, must, in any case, be
transmitted to and received by the Depositary at one of its addresses set forth
on the back cover of this Offer to Purchase prior to the Expiration Date, or the
guaranteed delivery procedures described below must be complied with. The term
"Agent's Message" means a message transmitted through electronic means by a
Book-Entry Transfer Facility to, and received by, the Depositary and forming a
part of a book-entry confirmation, which states that such Book-Entry Transfer
Facility has received an express acknowledgment from the participant in such
Book-Entry Transfer Facility tendering the Shares that such participant has
received, and agrees to be bound by, the terms of the Letter of Transmittal.
Delivery of documents to a Book-Entry Transfer Facility in accordance with the
Book-Entry Transfer Facility's procedures does not constitute delivery to the
Depositary.
 
    GUARANTEED DELIVERY.  If a shareholder desires to tender Shares pursuant to
the Offer and such shareholder's certificates representing Shares are not
immediately available (or the procedures for book-entry transfer cannot be
completed on a timely basis) or time will not permit all required documents to
reach the Depositary prior to the Expiration Date, such Shares may nevertheless
be tendered, provided that all of the following conditions are satisfied:
 
        (a) such tender is made by or through an Eligible Institution;
 
                                       5
<PAGE>
        (b) the Depositary receives, prior to the Expiration Date, a properly
    completed and duly executed Notice of Guaranteed Delivery, substantially in
    the form provided by the Purchaser; and
 
        (c) the certificates representing all tendered Shares in proper form for
    transfer (or confirmation of a book-entry transfer of such Shares into the
    Depositary's account at one of the Book-Entry Transfer Facilities), together
    with a properly completed and duly executed Letter of Transmittal (or
    facsimile thereof) with any required signature guarantees (or, in connection
    with a book-entry transfer, an Agent's Message) and any other documents
    required by the Letter of Transmittal are received by the Depositary within
    three trading days after the date of such Notice of Guaranteed Delivery. A
    "trading day" is any day on which the National Market of the Nasdaq Stock
    Market ("The Nasdaq National Market") is open for business.
 
    The Notice of Guaranteed Delivery may be delivered by hand, or may be
transmitted by telegram, telex, facsimile transmission or mail, to the
Depositary and must include a guarantee by an Eligible Institution in the form
set forth in such Notice of Guaranteed Delivery.
 
    In all cases, payment for Shares tendered and accepted for payment pursuant
to the Offer will be made only after timely receipt by the Depositary of (i)
certificates representing such Shares (or timely confirmation of a book-entry
transfer of such Shares into the Depositary's account at a Book-Entry Transfer
Facility), (ii) properly completed and duly executed Letter(s) of Transmittal
(or facsimile(s) thereof), together with any required signature guarantees (or,
in connection with a book-entry transfer, an Agent's Message), and (iii) any
other documents required by the Letter of Transmittal. Accordingly, tendering
shareholders may be paid at different times depending upon when certificates
representing Shares or confirmations of book-entry transfers of such Shares are
actually received by the Depositary.
 
    The method of delivery of all documents, including certificates for Shares,
is at the option and risk of the tendering shareholder, and the delivery will be
deemed made only when actually received by the Depositary. If delivery is by
mail, registered mail with return receipt requested, properly insured, is
recommended. In all cases, sufficient time should be allowed to ensure timely
delivery.
 
    DETERMINATION OF VALIDITY.  All questions as to the form of documents and
the validity, eligibility (including time of receipt) and acceptance for payment
of any tendered Shares will be determined by the Purchaser in its sole
discretion, and its determination shall be final and binding on all parties. The
Purchaser reserves the absolute right to reject any or all tenders of any Shares
that it determines are not in appropriate form or the acceptance for payment of
or payment for which may, in the opinion of the Purchaser's counsel, be
unlawful. The Purchaser also reserves the absolute right to waive any of the
conditions of the Offer or any defect or irregularity in any tender with respect
to any particular Shares or any particular shareholder, and the Purchaser's
interpretation of the terms and conditions of the Offer (including the Letter of
Transmittal and the Instructions thereto) will be final and binding on all
parties. No tender of Shares will be deemed to have been validly made until all
defects or irregularities relating thereto have been cured or expressly waived
to the satisfaction of the Purchaser. None of the Purchaser, Tyco, the
Depositary, the Information Agent or any other person will be under any duty to
give notification of any defects or irregularities in tenders, nor shall any of
them incur any liability for failure to give any such notification.
 
    OTHER REQUIREMENTS.  By executing the Letter of Transmittal, a tendering
shareholder irrevocably appoints designees of the Purchaser as such
shareholder's proxies, in the manner set forth in the Letter of Transmittal,
each with full power of substitution, to the full extent of such shareholder's
rights with respect to the Shares tendered by such shareholder and accepted for
payment by the Purchaser (and any and all other Shares or other securities or
rights issued or issuable in respect of such Shares on or after December 2,
1996), effective if, when and to the extent that the Purchaser accepts such
Shares for payment pursuant to the Offer. Upon such acceptance for payment, all
prior proxies given by such shareholder with respect to such Shares or other
securities accepted for payment will, without further action, be revoked, and no
subsequent proxies may be given by such shareholder nor any subsequent written
consents executed
 
                                       6
<PAGE>
(and, if given or executed, will not be deemed effective). Such designees of the
Purchaser will, with respect to such Shares and other securities or rights
issuable in respect thereof, be empowered to exercise all voting and other
rights of such shareholder as they, in their sole discretion, may deem proper in
respect of any annual, special or adjourned meeting of the Company's
shareholders, by written consent in lieu of any such meeting or otherwise. The
Purchaser reserves the right to require that, in order for Shares to be deemed
validly tendered, immediately upon the Purchaser's acceptance for payment of
such Shares the Purchaser must be able to exercise full voting rights with
respect to such Shares.
 
    The Purchaser's acceptance for payment of Shares tendered pursuant to any of
the procedures described above will constitute a binding agreement between the
tendering shareholder and the Purchaser upon the terms and subject to the
conditions of the Offer.
 
    TO PREVENT FEDERAL INCOME TAX BACKUP WITHHOLDING ON PAYMENTS MADE TO
SHAREHOLDERS WITH RESPECT TO SHARES PURCHASED PURSUANT TO THE OFFER, EACH
SHAREHOLDER MUST PROVIDE THE DEPOSITARY WITH HIS CORRECT TAXPAYER IDENTIFICATION
NUMBER AND CERTIFY THAT HE IS NOT SUBJECT TO BACKUP FEDERAL INCOME TAX
WITHHOLDING BY COMPLETING THE SUBSTITUTE FORM W-9 INCLUDED IN THE LETTER OF
TRANSMITTAL. FOREIGN HOLDERS MUST SUBMIT A COMPLETED FORM W-8 TO AVOID BACKUP
WITHHOLDING. THIS FORM MAY BE OBTAINED FROM THE DEPOSITARY. SEE INSTRUCTIONS 10
AND 11 OF THE LETTER OF TRANSMITTAL.
 
    3.  WITHDRAWAL RIGHTS.  Tenders of Shares made pursuant to the Offer will be
irrevocable, except that Shares tendered may be withdrawn at any time prior to
the Expiration Date, and, unless theretofore accepted for payment by the
Purchaser as provided herein, may also be withdrawn on or after February 4,
1997.
 
    For a withdrawal of Shares tendered to be effective, a written, telegraphic,
telex or facsimile transmission notice of withdrawal must be timely received by
the Depositary at one of its addresses set forth on the back cover of this Offer
to Purchase. Any notice of withdrawal must specify the name of the person who
tendered the Shares to be withdrawn, the number of Shares to be withdrawn and
the name(s) in which the certificate(s) representing such Shares are registered,
if different from that of the person who tendered such Shares. If certificates
for Shares to be withdrawn have been delivered or otherwise identified to the
Depositary, the name of the registered holder and the serial numbers shown on
the particular certificates evidencing such Shares to be withdrawn must also be
furnished to the Depositary prior to the physical release of the Shares to be
withdrawn. The signature(s) on the notice of withdrawal must be guaranteed by an
Eligible Institution (except in the case of Shares tendered by an Eligible
Institution). If Shares have been tendered pursuant to the procedures for
book-entry transfer set forth in Section 2, any notice of withdrawal must
specify the name and number of the account at the appropriate Book-Entry
Transfer Facility to be credited with such withdrawn Shares and must otherwise
comply with such Book-Entry Transfer Facility's procedures.
 
    If the Purchaser extends the Offer, is delayed in its acceptance for payment
of any Shares tendered, or is unable to accept for payment or pay for Shares
tendered pursuant to the Offer, for any reason whatsoever, then, without
prejudice to the Purchaser's rights set forth herein, the Depositary may,
nevertheless, on behalf of the Purchaser, retain tendered Shares, and such
Shares may not be withdrawn except to the extent that the tendering shareholder
is entitled to and duly exercises withdrawal rights as described in this Section
and as otherwise required by Rule 14e-1(c) under the Exchange Act. Any such
delay will be accompanied by an extension of the Offer to the extent required by
law.
 
    Withdrawals of tenders of Shares may not be rescinded, and Shares properly
withdrawn will thereafter be deemed not validly tendered for purposes of the
Offer. However, withdrawn Shares may be retendered by again following the
procedures described in Section 2 at any time prior to the Expiration Date.
 
    All questions as to the form and validity (including time of receipt) of
notices of withdrawal will be determined by the Purchaser, in its sole
discretion, and its determination will be final and binding on all parties. None
of the Purchaser, Tyco, the Depositary, the Information Agent or any other
person will be
 
                                       7
<PAGE>
under any duty to give notification of any defects or irregularities in any
notice of withdrawal, nor shall any of them incur any liability for failure to
give any such notification.
 
    4.  ACCEPTANCE FOR PAYMENT AND PAYMENT OF OFFER PRICE.  Upon the terms and
subject to the conditions of the Offer (including, if the Offer is extended or
amended, the terms and conditions of any extension or amendment), the Purchaser
will accept for payment and will pay for all Shares validly tendered prior to
the Expiration Date (and not properly withdrawn in accordance with Section 3
above) as soon as practicable after the latest to occur of (a) the expiration or
termination of the waiting period applicable to the acquisition of the Shares
pursuant to the Offer under the Hart-Scott-Rodino Antitrust Improvements Act of
1976, as amended (the "HSR Act"), (b) the Expiration Date, and (c) subject to
compliance with Rule 14e-1(c) under the Exchange Act, the satisfaction or waiver
of the conditions of the Offer set forth in Section 15. Any determination
concerning the satisfaction of such terms and conditions shall be within the
sole discretion of the Purchaser, and such determination shall be final and
binding on all tendering shareholders. See Section 15.
 
    The Purchaser expressly reserves the right to delay acceptance for payment
of, or payment for, Shares in order to comply in whole or in part with any
applicable law. If the Purchaser desires to delay payment for Shares accepted
for payment pursuant to the Offer, and such delay would otherwise be in
contravention of Rule 14e-1(c) of the Exchange Act, the Purchaser will formally
extend the Offer. In all cases, payment for Shares accepted for payment pursuant
to the Offer will be made only after timely receipt by the Depositary of (i)
certificates representing such Shares (or a timely confirmation of a book-entry
transfer of such Shares into the Depositary's account at one of the Book-Entry
Transfer Facilities, as described in Section 2), (ii) a properly completed and
duly executed Letter of Transmittal (or facsimile thereof) with any required
signature guarantees (or, in connection with a book-entry transfer, an Agent's
Message), and (iii) any other documents required by the Letter of Transmittal.
 
    For purposes of the Offer, the Purchaser will be deemed to have accepted for
payment, and thereby purchased, tendered Shares when, as and if the Purchaser
gives oral or written notice to the Depositary, as agent for the tendering
shareholders, of the Purchaser's acceptance for payment of such Shares. Payment
for Shares so accepted for payment will be made by the deposit of the purchase
price therefor with the Depositary, which will act as agent for the tendering
shareholders for the purpose of receiving such payment from the Purchaser and
transmitting such payment to tendering shareholders. If, for any reason
whatsoever, acceptance for payment of any Shares tendered pursuant to the Offer
is delayed, or the Purchaser is unable to accept for payment Shares tendered
pursuant to the Offer, then, without prejudice to the Purchaser's rights under
Section 1, the Depositary may, nevertheless, on behalf of the Purchaser, retain
tendered Shares, and such Shares may not be withdrawn, except to the extent that
the tendering shareholders are entitled to withdrawal rights as described in
Section 3 and as otherwise required by Rule 14e-1(c) under the Exchange Act.
Under no circumstances will interest be paid on the purchase price by reason of
any delay in making such payments.
 
    If any tendered Shares are not accepted for payment and paid for,
certificates representing such Shares will be returned (or, in the case of
Shares delivered by book-entry transfer with any Book-Entry Transfer Facility as
permitted by Section 2, such Shares will be credited to an account maintained
with such Book-Entry Transfer Facility) without expense to the tendering
shareholder as promptly as practicable following the expiration or termination
of the Offer.
 
    If, prior to the Expiration Date, the Purchaser increases the consideration
to be paid for Shares pursuant to the Offer, the Purchaser will pay such
increased consideration for all Shares accepted for payment pursuant to the
Offer, whether or not such Shares have been tendered or accepted for payment
prior to such increase in the consideration.
 
    The Purchaser reserves the right to transfer or assign in whole or in part
to one or more affiliates of the Purchaser or Tyco the right to purchase all or
any portion of the Shares tendered pursuant to the Offer, but any such transfer
or assignment will not relieve the Purchaser of its obligations under the Offer
and will
 
                                       8
<PAGE>
in no way prejudice the rights of tendering shareholders to receive payment for
Shares validly tendered and accepted for payment pursuant to the Offer.
 
    5.  CERTAIN FEDERAL INCOME TAX CONSEQUENCES.  The receipt of cash for Shares
pursuant to the Offer (or in the Merger) will be a taxable transaction for
federal income tax purposes (and may also be a taxable transaction under
applicable state, local or other tax laws). In general, a shareholder will
recognize gain or loss for such purposes equal to the difference between such
shareholder's adjusted tax basis for the Shares such shareholder sells in such
transaction and the amount of cash received therefor. Gain or loss must be
determined separately for each block of Shares (i.e., Shares acquired at the
same cost in a single transaction) sold pursuant to the Offer or converted to
cash in the Merger. Such gain or loss will be capital gain or loss if the Shares
are a capital asset in the hands of the shareholder and will be long term
capital gain or loss if the Shares were held for more than one year on the date
of sale (in the case of the Offer) or the Effective Time of the Merger (in the
case of the Merger). The receipt of cash for Shares pursuant to the exercise of
dissenters' rights, if any, will generally be taxed in the same manner described
above. Long-term capital gains for individuals currently are taxed at a maximum
rate of 28%. Legislative proposals may be introduced that would decrease the tax
rate applicable to an individual's long-term capital gains. It is not known
whether any such proposal will be enacted, and, if enacted, what the new rate
(if changed) will be and when any such new rate will become effective.
 
    Payments in connection with the Offer or the Merger may be subject to
"backup withholding" at a rate of 31%. Backup withholding generally applies if
the shareholder (a) fails to furnish his social security number or TIN, (b)
furnishes an incorrect TIN, or (c) under certain circumstances, fails to provide
a certified statement, signed under penalties of perjury, that the TIN provided
is his correct number and that he is not subject to backup withholding. Backup
withholding is not an additional tax but merely an advance payment, which may be
refunded to the extent it results in an overpayment of tax. Certain persons
generally are entitled to exemption from backup withholding, including
corporations and financial institutions. Certain penalties apply for failure to
furnish correct information and for failure to include reportable payments in
income. Each shareholder should consult with his own tax advisor as to his
qualification for exemption from backup withholding and the procedure for
obtaining such exemption. Tendering shareholders may be able to prevent backup
withholding by completing the Substitute Form W-9 included in the Letter of
Transmittal.
 
    The foregoing discussion may not be applicable to a shareholder who acquired
Shares pursuant to the exercise of employee stock options or otherwise as
compensation, or to a shareholder who is not a citizen or resident of the United
States or who is otherwise subject to special tax treatment under the Internal
Revenue Code. In addition, the foregoing discussion does not address the tax
treatment of holders of Stock Options (as defined in Section 13).
 
    The federal income tax discussion set forth above is included for general
information only and is based upon present law. Shareholders are urged to
consult their tax advisors with respect to the specific tax consequences of the
Offer and the Merger to them, including the application and effect of the
alternative minimum tax, and state, local or foreign income and other tax laws.
 
    6.  PRICE RANGE OF SHARES; DIVIDENDS.  The Shares commenced trading on The
Nasdaq National Market on December 21, 1995 under the symbol "ESTR." The
following table sets forth, for the periods indicated, the high and low closing

    On November 27, 1996, the last full trading day prior to the public
announcement of the terms of the Offer and the Merger, the closing per Share
sales price on The Nasdaq National Market was $13.00. On December 4, 1996, the
last full trading day prior to commencement of the Offer, the closing per Share
sales price on The Nasdaq National Market was $13 13/16. Shareholders are urged
to obtain a current market quotation for the Shares.
 
    7.  EFFECTS OF THE OFFER ON THE MARKET FOR SHARES; STOCK QUOTATIONS;
REGISTRATION UNDER THE EXCHANGE ACT.  The purchase of Shares pursuant to the
Offer will reduce the number of holders of Shares and the number of Shares that
might otherwise trade publicly. Consequently, depending upon the number of
Shares purchased and the number of remaining holders of Shares, the purchase of
Shares pursuant to the Offer may adversely affect the liquidity and market value
of the remaining Shares held by the public. The Purchaser cannot predict whether
the reduction in the number of Shares that might otherwise trade publicly would
have an adverse or beneficial effect on the market price for, or marketability
of, the Shares or whether it would cause future market prices to be greater or
less than the Offer price.
 
    The Shares are currently listed and traded on The Nasdaq National Market,
which constitutes the principal trading market for the Shares. Depending upon
the aggregate market value and the number of Shares not purchased pursuant to
the Offer, the Shares may no longer meet the quantitative maintenance criteria
of the National Association of Securities Dealers, Inc. (the "NASD") for
continued inclusion on The Nasdaq National Market and may cease to be authorized
for quotation on such markets. The Nasdaq National Market's published guidelines
require that an issuer have at least 200,000 publicly held shares (exclusive of
holdings of officers, directors or beneficial owners of more than 10%), held
either by at least 400 beneficial shareholders or 300 beneficial shareholders of
round lots, with a market value of at least $1 million and must have net
tangible assets of at least either $1 million, $2 million or $4 million
depending on profitability levels during the issuer's four most recent fiscal
years. If these standards are not met, shares of an issuer might nevertheless
continue to be included in The Nasdaq Stock Market with quotations published in
The Nasdaq Stock Market's "additional list" or in one of the "local lists," but
if the number of beneficial holders were to fall below 300, or if the number of
publicly held shares were to fall below 100,000 or there were not at least two
registered and active market makers for the Shares, the NASD's rules provide
that such shares would no longer be "qualified" for reporting by The Nasdaq
Stock Market.
 
    If, as a result of the purchase of Shares pursuant to the Offer or
otherwise, the Shares no longer meet the requirements of the NASD for continued
inclusion in The Nasdaq National Market or in any other tier of The Nasdaq Stock
Market, and the Shares are no longer included in The Nasdaq National Market or
in any other tier of The Nasdaq Stock Market, the market for Shares could be
adversely affected.
 
    In the event that the Shares no longer meet the requirements of the NASD for
continued inclusion in any tier of The Nasdaq Stock Market, it is possible that
Shares would continue to trade in the over-the-counter market and that price
quotations would be reported by other sources. The extent of the public market
for the Shares and the availability of such quotations would, however, depend
upon the number of holders of Shares remaining at such time, the interest in
maintaining a market in Shares on the part of securities firms, the possible
termination of registration of the Shares under the Exchange Act, as described
below, and other factors.
 
                                       10
<PAGE>
    The Shares are currently registered under the Exchange Act. Such
registration may be terminated upon application of the Company to the Commission
if such Shares are not listed on a national securities exchange and there are
fewer than 300 holders of record of the Shares. The termination of the
registration of the Shares under the Exchange Act would substantially reduce the
information required to be furnished by the Company to its shareholders and to
the Commission, and would make certain of the provisions of the Exchange Act,
such as the short-swing profit recovery provisions of Section 16(b) and the
requirement of furnishing a proxy statement in connection with shareholders'
meetings and the related requirement of an annual report to shareholders, and
the requirements of Rule 13e-3 with respect to going private transactions, no
longer applicable with respect to the Shares or to the Company. Furthermore, if
registration of the Shares under the Exchange Act were terminated, the ability
of "affiliates" of the Company and persons holding "restricted securities" of
the Company to dispose of such securities pursuant to Rule 144 promulgated under
the Securities Act of 1933, as amended, may be impaired or, with respect to
certain persons, eliminated. According to the Company, as of December 2, 1996,
there were approximately 11 holders of record of Shares.
 
    The Shares are currently "margin securities" under the regulations of the
Board of Governors of the Federal Reserve System (the "Federal Reserve Board"),
which has the effect, among other things, of allowing brokers to extend credit
on such Shares as collateral. Depending on factors similar to those described
above regarding listing and market quotations, it is possible the Shares would
no longer constitute "margin securities" for purposes of the Federal Reserve
Board's margin regulations and therefore could no longer be used as collateral
for loans made by brokers. If registration of Shares under the Exchange Act were
terminated, the Shares would no longer be "margin securities."
 
    8.  CERTAIN INFORMATION CONCERNING THE COMPANY.  Except as otherwise set
forth herein, the information concerning the Company contained in this Offer to
Purchase, including financial information, has been furnished by the Company or
has been taken from or based upon publicly available documents and records on
file with the Commission and other public sources. Although neither the
Purchaser nor Tyco has any knowledge that would indicate that the statements
contained herein based on such information are untrue, neither the Purchaser nor
Tyco takes any responsibility for the accuracy or completeness of the
information concerning the Company furnished by the Company or contained in such
documents and records or for any failure by the Company to disclose events or
information which may have occurred or may affect the significance or accuracy
of any such information but which are unknown to the Purchaser or Tyco.
 
    The Company was incorporated in December 1994 under the laws of the State of
Florida under the name "Interconnect Technology, Inc." and changed its name to
"ElectroStar, Inc." in August 1995. The Company has two subsidiaries, Lundahl
Astro Circuits, Inc. ("Lundahl") and Electro-Etch Circuits, Inc. ("ElectroEtch")
Lundahl was acquired in November 1993 by LAC Acquisitions Corp., which merged
into Lundahl. ElectroEtch was acquired in December 1994 by EE Acquisition
Corporation, a subsidiary of ElectroStar that merged into ElectroEtch. In
connection with the acquisition of ElectroEtch in December 1994, the
shareholders of Lundahl exchanged their shares of stock for shares of
ElectroStar, resulting in the current corporate structure of the Company. The
Company's principal executive offices are located at 710 North 600 West, Logan,
Utah 84321 and its telephone number is (801) 753-4700. The following description
of the Company's business has been taken from the Company's 1995 Annual Report:
 
        "[The Company] produces complex printed circuit boards [("PCBs")],
    ranging from double-sided to 20 layers, that are used in the manufacture of
    sophisticated electronic equipment. The Company seeks to establish long-term
    relationships with its customers by also providing flexible manufacturing
    services, including computer aided manufacturing and engineering services
    and quick-turnaround manufacturing of prototype and preproduction PCBs."

    9.  CERTAIN INFORMATION CONCERNING TYCO AND THE PURCHASER.  The Purchaser is
a newly formed Florida corporation and a wholly owned subsidiary of Tyco. To
date, the Purchaser has not conducted any business other than incident to its
formation, the execution and delivery of the Merger Agreement and the
commencement of the Offer.
 
    Tyco, a Massachusetts corporation, is a global manufacturer, installer and
distributor of products and systems for a broad spectrum of markets, including
disposable medical products, packaging, life and life
 
                                       12
<PAGE>
safety, industrial process control and telecommunications. Tyco's Printed
Circuit Group is a leading manufacturer of complex multi-layered printed circuit
boards and assembler of backplanes in the northeastern United States. The
principal executive offices of Tyco and the Purchaser are located at One Tyco
Park, Exeter, New Hampshire 03833.
 
    Until immediately prior to the time that the Purchaser purchases Shares
pursuant to the Offer, it is not anticipated that Purchaser will have any
significant assets or liabilities or engage in activities other than those
incident to its formation and capitalization and the transactions contemplated
by the Offer and the Merger. Since the Purchaser is newly formed and has minimal
assets and capitalization, no meaningful financial information is available.
 
    Set forth below is certain selected historical consolidated financial
information with respect to Tyco excerpted or derived from financial information
contained in Tyco's Annual Report on Form 10-K for the year ended June 30, 1996,

reports are hereby incorporated by reference herein). More comprehensive
financial information is included in such reports and other documents filed by
Tyco with the Commission, and the following summary is qualified in its entirety
by reference to such reports and such other documents and of the financial
information (including any related notes) contained therein. Such reports and
other documents should be available for inspection and copies thereof should be
obtainable in the manner set forth in Section 8. Such reports and other
documents should also be available for inspection at the offices of the New York

    The name, citizenship, business address, present principal occupation or
employment and five year employment history of each of the directors and
executive officers of Tyco and the Purchaser are set forth in Annex I hereto.
 
    None of Tyco or the Purchaser or, to the best of their knowledge, any of the
persons listed on Annex I hereto, or any associate or majority-owned subsidiary
of Tyco, the Purchaser or any of the persons so listed,
 
                                       13
<PAGE>
owns or has the right to acquire any Shares (except pursuant to the Shareholder
Agreement described in Section 13) or has effected any transaction in the Shares
during the past 60 days.
 
    Except as set forth in this Offer to Purchase, none of Tyco or the Purchaser
or, to the best of their knowledge, any of the persons listed in Annex I hereto,
(a) has any contract, arrangement, understanding or relationship with any other
person with respect to any securities of the Company, including, but not limited
to, any contract, arrangement, understanding or relationship concerning the
transfer or the voting of any securities of the Company, joint ventures, loan or
option arrangements, puts or calls, guaranties of loans, guaranties against
loss, or the giving or withholding of proxies; (b) has engaged in contacts,
negotiations or transactions with the Company or its affiliates concerning a
merger, consolidation, acquisition, tender offer or other acquisition of
securities, election of directors or a sale or other transfer of a material
amount of assets; or (c) has had any other transaction with the Company or any
of its executive officers, directors or affiliates that would require disclosure
under the rules and regulations of the Commission applicable to the Offer.
 
    10.  SOURCE AND AMOUNT OF FUNDS.  The total amount of funds required by Tyco
and the Purchaser to purchase all Shares that may be tendered pursuant to the
Offer and in the Merger, and to pay related fees and expenses, is estimated to
be approximately $113 million.
 
    The Purchaser will obtain all such funds from Tyco or its affiliates. Tyco
has sufficient financial resources to satisfy its and the Purchaser's
obligations under the Offer and the Merger Agreement. This Offer is not
conditioned upon any financing arrangements.
 
    11.  CONTACTS WITH THE COMPANY; BACKGROUND OF THE OFFER.  On or about
October 9, 1996, Tyco requested Robertson, Stephens & Company LLC ("Robertson
Stephens") to contact the Company on behalf of Tyco to present Tyco's potential
interest in acquiring the Company. Following such contact, on October 28 and 29,
1996, J. Brad McGee, Vice President of Tyco, and other representatives of Tyco
met with Kenton K. Alder, President and Chief Executive Officer of the Company,
John Mayer, Chief Operating Officer of the Company, and Michael E. Moran, Senior
Vice President of Trivest, Inc., the Company's financial advisor ("Trivest").
The Tyco representatives visited the Company's manufacturing facilities in
Inglewood, California and Logan, Utah and obtained information about the Company
and provided the Company with certain information concerning Tyco.
 
    On November 1, 1996 Tyco and the Company executed a confidentiality
agreement. Also on November 1, 1996, Trivest invited Tyco to submit an
indication of interest in acquiring the stock of the Company.
 
    On November 12, 1996 Tyco, through Robertson Stephens, verbally expressed an
interest in acquiring the stock of the Company for $14.00 per share. Tyco
indicated that financing the transaction would be through existing financing
sources of Tyco and that due diligence could start immediately. Between November
12, and November 18, 1996 representatives of Tyco and the Company conducted
several discussions concerning the possibility of an acquisition transaction,
including with respect to price, structure, timing, due diligence and Tyco's
valuation analysis.
 
    On November 18, 1996 the Company and Tyco executed an exclusivity and
standstill agreement which, among other things, provided Tyco exclusive access
to non-public information concerning the Company until November 22, 1996, so
that Tyco could perform a definitive evaluation of an acquisition of the Company
by Tyco, and also contained Tyco's agreement to certain standstill provisions.
The exclusivity and standstill agreement was extended on November 22, 1996 until
November 27, 1996. During the week of November 18, 1996, representatives of Tyco
conducted a due diligence review of the Company's business and held discussions
concerning the review with representatives of the Company. Between November 25
and November 27, 1996, the legal advisors of Tyco and the Company negotiated the
terms of the Merger Agreement and the Shareholder Agreement, drafts of which had
been previously furnished by the Company to Tyco.
 
                                       14
<PAGE>
    On November 27, 1996, the Board of Directors of Tyco considered the proposal
to acquire the Company. Following the presentation of Tyco's management, Tyco's
Board voted to approve an offer to acquire the Company for $14.00 per Share
substantially on the terms set forth in the Merger Agreement.
 
    On November 27, 1996, following the action of Tyco's Board, the Board of
Directors of the Company met to consider the Tyco offer. The Company's Board
reviewed the terms of the Merger Agreement and received the opinion of Alex.
Brown that the offer price of $14.00 per share was fair to the shareholders of
the Company from a financial point of view. Thereafter, the Board of Directors
of the Company unanimously approved the Merger Agreement, the Offer and the
Merger. On November 27, 1996, Tyco, the Purchaser and the Company executed the
Merger Agreement. Public disclosure of the Merger Agreement was made on the
morning of November 29, 1996, prior to the opening of trading of Shares on The
Nasdaq National Market.
 
    12.  PURPOSE OF THE OFFER; SHORT FORM MERGER; PLANS FOR THE COMPANY;
DISSENTERS' RIGHTS; GOING PRIVATE TRANSACTIONS.
 
    PURPOSE OF THE OFFER.  The purpose of the Offer is for the Purchaser to
acquire control of, and a majority equity interest in, the Company. The purpose
of the Merger is to acquire all outstanding Shares not tendered and purchased
pursuant to the Offer. The acquisition of the entire equity interest in the
Company has been structured as a cash tender offer followed by a cash merger in
order to provide a prompt and orderly transfer of ownership of the Company from
the public shareholders to Tyco and to provide shareholders with cash for all of
their Shares.
 
    Under the FBCA and the Company's Articles of Incorporation, the approval of
the Board of Directors of the Company and the affirmative vote of a majority of
the holders of outstanding Shares are required to approve and adopt the Merger
Agreement and the Merger. The Board of Directors of the Company has approved the
Offer, the Merger and the Merger Agreement and the transactions contemplated
thereby, and, unless the Merger is consummated pursuant to the short-form merger
provisions under the FBCA described below, the only remaining required corporate
action of the Company is the approval and adoption of the Merger Agreement and
the Merger by the affirmative vote of the holders of a majority of the
outstanding Shares. If the Minimum Condition is satisfied, the Purchaser will
have sufficient voting power to cause the approval and adoption of the Merger
Agreement and the Merger without the affirmative vote of any other shareholder.
Beneficial owners of approximately 61% (57% on a fully diluted basis) of the
total number of outstanding Shares of the Company have agreed to tender all of
their Shares pursuant to the Offer.
 
    The Merger Agreement provides that, if approval of the Merger by the
shareholders of the Company is required by law, the Company will, as soon as
possible following payment for Shares in the Offer, duly call and hold a meeting
of shareholders for the purpose of obtaining shareholder approval of the Merger,
and the Company, through its Board of Directors, will recommend to shareholders
that such approval be given.
 
    SHORT FORM MERGER.  Under the FBCA, if the Purchaser acquires at least 80%
of the outstanding Shares, the Purchaser will be able to approve the Merger
without a vote of the Company's other shareholders. The Merger Agreement
provides that if the Purchaser, or any other direct or indirect subsidiary of
Tyco, acquires at least 80% of the outstanding Shares, Tyco, the Purchaser and
the Company will take all necessary and appropriate action to cause the Merger
to become effective as soon as practicable after the expiration of the Offer
without a meeting of shareholders of the Company, in accordance with Section
607.1104 of the FBCA. Among other things, Section 607.1104 provides that the
articles of merger may not be filed with the Florida Department of State until
at least 30 days after the date a copy or summary of the plan of merger is
mailed to each shareholder of the Company who did not waive such mailing
requirement or, if earlier, upon the waiver thereof by the holders of all the
Shares. In the event that all of the conditions to the Purchaser's obligation to
purchase Shares in the Offer are satisfied or waived and the number of Shares
tendered is less than 80% of the outstanding Shares, the
 
                                       15
<PAGE>
Purchaser may, subject to the limitations set forth in the Merger Agreement,
extend the Offer for an aggregate period of not more than 10 business days (for
all such extensions) without the consent of the Company. See Section 1. If the
Purchaser does not acquire at least 80% of the outstanding Shares, a
significantly longer period of time may be required to effect the Merger,
because a vote of the Company's shareholders would be required under the FBCA.
 
    PLANS FOR THE COMPANY.  Except as otherwise set forth in this Offer to
Purchase, it is expected that, initially following the Merger, the business and
operations of the Company will be continued by the Surviving Corporation
substantially as they are currently being conducted. The directors of the
Purchaser will be the initial directors of the Surviving Corporation, and the
officers of the Company and such other persons as are designated by Tyco will be
the initial officers of the Surviving Corporation. Upon completion of the Offer,
Tyco intends to conduct a detailed review of the Company and its assets,
corporate structure, capitalization, operations, policies, management and
personnel. After such review, Tyco will determine what actions or changes, if
any, would be desirable in light of the circumstances which then exist, and
reserves the right to effect such actions or changes.
 
    Except as described in this Offer to Purchase, neither Tyco nor the
Purchaser has any present plans or proposals that would relate to or result in
(i) any extraordinary corporate transaction, such as a merger, reorganization or
liquidation, involving the Company or any of its subsidiaries, (ii) a sale or
transfer of a material amount of assets of the Company or any of its
subsidiaries, (iii) any change in the Company's Board of Directors or
management, (iv) any material change in the Company's capitalization or dividend
policy, (v) any other material change in the Company's corporate structure or
business, (vi) a class of securities of the Company to be delisted from a
national securities exchange or to cease to be authorized to be quoted in an
inter-dealer quotation system of a registered national securities association,
or (vii) a class of equity securities of the Company becoming eligible for
termination of registration pursuant to Section 12(g) of the Exchange Act.
 
    DISSENTERS' RIGHTS.  Pursuant to Section 607.1302 of the FBCA, holders of
shares do not have dissenters' rights as a result of the Offer. If the Merger is
effected with a vote of the Company's shareholders and if on the record date
fixed to determine the shareholders entitled to vote, the Shares are registered
on a national securities exchange or designated as a national market system
security on an interdealer quotation system by the NASD or are held of record by
2,000 or more of such shareholders, then holders of the Shares will not have
dissenters' rights under the FBCA. If, however, the Merger is consummated with
or without the vote of the Company's shareholders but the Shares are not so
listed or designated or are not held of record by at least 2,000 shareholders,
holders of Shares will have certain rights pursuant to the provisions of
Sections 607.1301, 607.1302, and 607.1320 of the FBCA to dissent and demand
determination of and to receive payment in cash of the fair value of, their
Shares. If the statutory procedures are complied with, such rights could lead to
a judicial determination of the fair value required to be paid in cash to such
dissenting holders for their Shares. Any such judicial determination of the fair
value of the Shares or the market value of the Shares could be more or less than
the Offer Price or the price provided for in the Merger Agreement. Section
607.1301(2) of FBCA defines "fair value" as the value of the shares excluding
any appreciation or depreciation in anticipation of the transaction in question
unless such exclusion would be inequitable.
 
    If any holder of Shares who asserts dissenters' rights under the FBCA fails
to perfect, or effectively withdraws or loses his or her dissenters' rights, as
provided in the FBCA, the Shares of such shareholder will be converted into the
right to receive the Merger Consideration provided for in the Merger Agreement
in accordance with the Merger Agreement. A shareholder may withdraw his or her
notice of election to dissent by delivery of a written withdrawal of his or her
notice of election to dissent.
 
    GOING PRIVATE TRANSACTIONS.  The Merger would have to comply with any
applicable Federal law operative at the time. The Commission has adopted Rule
13e-3 under the Exchange Act which is applicable to certain "going private"
transactions and which may under certain circumstances be applicable
 
                                       16
<PAGE>
to the Merger or another business combination following the purchase of Shares
pursuant to the Offer in which the Purchaser or Tyco seeks to acquire the
remaining Shares not held by it. The Purchaser believes, however, that Rule
13e-3 will not be applicable to the Merger. If applicable, Rule 13e-3 requires,
among other things, that certain financial information concerning the Company
and certain information relating to the fairness of such transaction and the
consideration offered to minority shareholders in such transaction be filed with
the Commission and disclosed to shareholders prior to the consummation of such
transaction.
 
    13.  THE MERGER AGREEMENT; SHAREHOLDER AGREEMENT.
 
    THE MERGER AGREEMENT
 
    The following summary of certain provisions of the Merger Agreement, a copy
of which is filed as an exhibit to the Schedule 14D-1, is qualified in its
entirety by reference to the text of the Merger Agreement.
 
    THE OFFER.  The Purchaser commenced the Offer in accordance with the terms
of the Merger Agreement.
 
    THE MERGER.  The Merger Agreement provides that, upon the terms and subject
to the conditions of the Merger Agreement, and in accordance with the FBCA, the
Purchaser shall be merged with and into the Company. Following the Effective
Time, the separate corporate existence of the Purchaser will cease and the
Company will continue as the Surviving Corporation and will succeed to and
assume all the rights and obligations of the Purchaser in accordance with the
FBCA. The Articles of Incorporation of the Company, as in effect immediately
prior to the Effective Time, will be the Articles of Incorporation of the
Surviving Corporation, except that the capital stock of the Surviving
Corporation will consist of 1,000 shares of common stock and certain provisions
not appropriate for a wholly-owned subsidiary will be eliminated. The bylaws of
the Purchaser prior to the Effective Time will be the bylaws of the Surviving
Corporation.
 
    CONVERSION OF SHARES.  At the Effective Time, each then outstanding Share
(other than Shares owned by the Company, any subsidiary of the Company, Tyco,
the Purchaser, any other subsidiary of Tyco or by shareholders, if any, who are
entitled to and who properly exercise dissenters' rights under Florida law) will
be converted into the right to receive an amount in cash equal to the price per
Share paid pursuant to the Offer.

subject to the satisfaction of the following conditions: (a) if required by

order, decree, temporary restraining order, preliminary or permanent injunction

domestic, foreign or supranational (a "Governmental Entity") or other legal

paid for Shares pursuant to the Offer.

        (3) by Tyco or the Purchaser if (i) the representation and warranties of
    the Company with respect to the capitalization of the Company shall not have
    been true and correct in all material respects when made or any other
    representation or warranty of the Company shall not have been true and
    correct in
 
                                       19
<PAGE>
    all material respects when made, except in any case where such failure to be
    true and correct would not, in the aggregate, (x) have a material adverse
    effect (as defined) on the Company, or (y) prevent or materially delay the
    consummation of the Offer and/or the Merger; (ii) the representation and
    warranties of the Company with respect to the capitalization of the Company
    (other than representations and warranties made as of a specific date) shall
    have ceased at any later date to be true and correct in all material
    respects as if made at such later date or any other representation or
    warranty of the Company (other than representations and warranties made as
    of a specific date) shall have ceased at any later date to be true and
    correct in all material respects as if made at such later date, except in
    any case where such failure to be true and correct would not, in the
    aggregate, (x) have a material adverse effect, or (y) prevent or materially
    delay the consummation of the Offer and/or the Merger; or (iii) the Company
    shall have failed to comply in any material respect with any of its material
    obligations or covenants contained in the Merger Agreement; PROVIDED,
    HOWEVER, that the right of Tyco or the Purchaser to terminate this Agreement
    pursuant to this paragraph (3) shall not be available if the Purchaser or
    any affiliate of the Purchaser shall acquire any Shares pursuant to the
    Offer;
 
        (4) by Tyco or the Purchaser if either Tyco or the Purchaser is
    entitled, pursuant to the Merger Agreement, to terminate the Offer as a
    result of (i) the Board of Directors of the Company having withdrawn or
    modified in a manner adverse to Tyco or the Purchaser its approval or
    recommendation of the Offer, the Merger or the Merger Agreement, or approved
    or recommended any Acquisition Proposal (as defined below), (ii) the Company
    having entered into any agreement with respect to any Superior Proposal (as
    defined below) as described under "Acquisition Proposals" below or (iii) the
    Board of Directors of the Company shall have resolved to take any of the
    actions set forth in clauses 4(i) and 4(ii) above; or
 
        (5) by the Company in connection with entering into a definitive
    agreement with respect to a Superior Proposal as described below under
    "Acquisition Proposals," provided it has complied with certain provisions of
    the Merger Agreement with respect thereto, including notice to Tyco and the
    payment of the Termination Fee (as defined below under "Expenses and
    Termination Fee"), and provided that the Company shall not have breached in
    any material respect the other provisions described below under "Acquisition
    Proposals"; or
 
        (6) by the Company if (x) any representation or warranty of Tyco or the
    Purchaser shall not have been true and correct in all material respects when
    made or shall have ceased at any later date to be true and correct in all
    material respects as if made at such later date; or (y) Tyco or the
    Purchaser shall have failed to comply in any material respect with any of
    its material obligations or covenants contained in the Merger Agreement.
 
    In the event of the termination of the Merger Agreement, the Merger
Agreement shall forthwith become void and there shall be no liability on the
part of any party thereto except as described under "Expenses and Termination
Fee" below or as otherwise expressly provided for in the Merger Agreement;
PROVIDED, HOWEVER, that nothing in the Merger Agreement will relieve any party
from liability for any breach thereof.
 
    ACQUISITION PROPOSALS.  Pursuant to the Merger Agreement, the Company has
agreed that the Company and its officers, directors, employees, representatives
and agents will cease any discussions or negotiations with any parties with
respect to any Acquisition Proposal (as defined below). The Merger Agreement
further provides that the Company will not, nor will it permit any of its
subsidiaries to, authorize or permit any of its officers, directors or employees
or any investment banker, financial advisor, attorney, accountant or other
representative retained by it or any of its subsidiaries, directly or
indirectly, (1) to solicit, initiate or encourage (including by way of
furnishing information), or take any other action to facilitate, any inquiries
or the making of any proposal which constitutes, or may reasonably be expected
to lead to, any Acquisition Proposal or (2) to participate in any discussions or
negotiations regarding any Acquisition Proposal; PROVIDED, HOWEVER, that if, at
any time prior to the acceptance for payment of Shares pursuant to the Offer,
the Board of Directors of the Company determines in good faith, after
consultation
 
                                       20
<PAGE>
with outside counsel, that it is necessary to do so in order to comply with its
fiduciary duties to the Company's shareholders under applicable law, the Company
may, in response to an unsolicited Acquisition Proposal, and subject to
compliance with the notification provisions discussed below, (i) furnish
information with respect to the Company to any person pursuant to a
confidentiality agreement in reasonably customary form and (ii) participate in
negotiations regarding such Acquisition Proposal. The Merger Agreement defines
"Acquisition Proposal" as any inquiry, proposal or offer from any person
relating to any direct or indirect acquisition or purchase of 20% or more of the
assets of the Company and its subsidiaries or 20% or more of any class of equity
securities of the Company or any of its subsidiaries, any tender offer or
exchange offer that if consummated would result in any person beneficially
owning 20% or more of any class of equity securities of the Company or any of
its subsidiaries, any merger, consolidation, business combination, sale of all
or substantially all the assets, recapitalization, liquidation, dissolution or
similar transaction involving the Company or any of its subsidiaries (other than
transactions between the parties to, and contemplated by, the Merger Agreement),
or any other transaction the consummation of which could reasonably be expected
to impede, interfere with, prevent or materially delay the Offer or the Merger
or which could reasonably be expected to dilute materially the benefits to Tyco
of the transactions contemplated thereby.
 
    The Merger Agreement provides further that, except as described below,
neither the Board of Directors of the Company nor any committee thereof shall
(i) withdraw or modify, or propose to withdraw or modify, in a manner adverse to
Tyco, the approval or recommendation by the Board of Directors or such committee
of the Offer, the Merger Agreement or the Merger, (ii) approve or recommend, or
propose to approve or recommend, any Acquisition Proposal or (iii) cause the
Company to enter into any agreement with respect to any Acquisition Proposal.
Notwithstanding the foregoing, in the event that prior to the acceptance for
payment of Shares pursuant to the Offer the Board of Directors of the Company
determines in good faith, after consultation with outside counsel, that it is
necessary to do so in order to comply with its fiduciary duties to the Company's
shareholders under applicable law, the Board of Directors may (subject to the
other provisions regarding Acquisition Proposals) withdraw or modify its
approval or recommendation of the Offer, the Merger Agreement or the Merger,
approve or recommend a Superior Proposal, cause the Company to enter into an
agreement with respect to a Superior Proposal or terminate the Merger Agreement,
in each case at any time after the fifth business day following Tyco's receipt
of written notice advising Tyco that the Board of Directors of the Company has
received a Superior Proposal, specifying the material terms and conditions of
such Superior Proposal and identifying the person making such Superior Proposal.
In addition, if the Company proposes to enter into an agreement with respect to
any Acquisition Proposal, it must concurrently with entering into such agreement
pay, or cause to be paid, to Tyco the Termination Fee. See "Expenses and
Termination Fee". For purposes of the Merger Agreement, a "Superior Proposal"
means any bona fide proposal to acquire, directly or indirectly, for
consideration consisting of cash and/or securities, more than 20% of the Shares
then outstanding or all or substantially all the assets of the Company and
otherwise on terms which the Board of Directors of the Company determines in its
good faith judgment (based on the advice of a financial advisor of nationally
recognized reputation) to be more favorable to the Company's shareholders than
the Offer and the Merger.
 
    In addition to the obligations of the Company described in the preceding two
paragraphs, the Merger Agreement provides that the Company shall immediately
advise Tyco orally and in writing of any request for information or of any
Acquisition Proposal, the material terms and conditions of such request or
Acquisition Proposal and the identity of the person making any such request or
Acquisition Proposal.
 
    The Merger Agreement provides that nothing contained therein shall prohibit
the Company from taking and disclosing to its shareholders a position
contemplated by Rule 14e-2(a) promulgated under the Exchange Act or from making
any disclosure to the Company's shareholders if, in the good faith judgment of
the Board of Directors of the Company, after consultation with outside counsel,
failure to so disclose would be inconsistent with its fiduciary duties to the
Company's shareholders under applicable law;
 
                                       21
<PAGE>
PROVIDED, HOWEVER, that neither the Company nor its Board of Directors nor any
committee thereof shall, except as permitted by the Merger Agreement and as
described above, withdraw or modify, or propose to withdraw or modify, its
position with respect to the Merger or approve or recommend, or propose to
approve or recommend, an Acquisition Proposal.
 
    EXPENSES AND TERMINATION FEE.  Except as described below, whether or not the
Merger is consummated, all costs and expenses incurred in connection with the
Merger Agreement and the transactions contemplated thereby will be paid by the
party incurring such costs and expenses. The Merger Agreement provides that the
Company will pay, or cause to be paid, to Tyco a termination fee of $3,000,000
(the "Termination Fee") if (i) Tyco or the Purchaser terminates the Merger
Agreement by reason of the failure of the Company to comply with its material
obligations or covenants, as described in clause (3)(iii) under "Termination of
the Merger Agreement" above, or the Company or its Board of Directors has
withdrawn or modified its approval of the Offer or the Merger, recommended an
Acquisition Proposal, entered into an agreement with respect to a Superior
Proposal or resolved to do any of the foregoing, as described in clause (4)
under "Termination of the Merger Agreement" above, (ii) either Tyco or the
Company terminates the Merger Agreement as described under clause 2(a) under
"Termination of the Merger Agreement" above, the Minimum Condition has failed to
be satisfied and such failure is the result of a breach by any of the parties to
the Shareholder Agreement (as defined below) of its obligation thereunder to
tender its Shares in the Offer or (iii) the Company terminates the Merger
Agreement in connection with entering into a definitive agreement with respect
to any Superior Proposal, as described under clause (5) of "Termination of the
Merger Agreement" above.
 
    BOARD OF DIRECTORS.  The Merger Agreement provides that promptly upon the
acceptance for payment of, and payment for, a majority of the outstanding Shares
by the Purchaser pursuant to the Offer, Tyco shall be entitled to designate such
number of directors, rounded up to the next whole number, on the Board of
Directors of the Company as will give Tyco, subject to compliance with Section
14(f) of the Exchange Act, representation on the Board of Directors equal to the
product of (x) the total number of directors on the Board of Directors and (y)
the percentage that the number of Shares purchased by the Purchaser bears to the
number of Shares outstanding; PROVIDED, HOWEVER, that in the event that Tyco's
designees are elected to the Board of Directors, until the Effective Time such
Board of Directors shall have at least two directors who were directors on the
date of the Merger Agreement and who are not officers of the Company (the
"Independent Directors"); and PROVIDED FURTHER that, in such event, if the
number of Independent Directors shall be reduced below two, the remaining
Independent Director shall fill such vacancy or, if no Independent Director then
remains, the other directors shall designate two persons who shall not be
officers or affiliates of the Company or any of its subsidiaries, or officers or
affiliates of Tyco or any of its subsidiaries, to fill such vacancies, and such
persons shall be deemed Independent Directors for purposes of the Merger
Agreement. Subject to applicable law, the Company has agreed to take all action
requested by Tyco necessary to effect any such election, including mailing to
its shareholders the Information Statement containing the information required
by Section 14(f) of the Exchange Act and Rule 14f-1 promulgated thereunder,
which Information Statement is attached as Annex A to the Schedule 14D-9, and
increasing the size of the Board of Directors and/or obtaining the resignation
of such number of the current directors of the Company.
 
    Following the election or appointment of the Tyco designated directors, the
affirmative vote of a majority of the Independent Directors then in office will
be required by the Company to (i) amend or terminate the Merger Agreement by the
Company, (ii) exercise or waive any of the Company's rights or remedies under
the Merger Agreement or (iii) extend the time for performance of Tyco's and the
Purchaser's respective obligations under the Merger Agreement.
 
    STOCK OPTIONS.  Pursuant to the Merger Agreement, Tyco and the Company have
agreed, effective as of the Effective Time, (i) to cause each outstanding option
to purchase Shares (a "Company Stock Option") issued pursuant to the Company's
Second Amended and Restated Stock Option Plan, whether or
 
                                       22
<PAGE>
not exercisable or vested, to become fully exercisable and vested, (ii) cause
each Company Stock Option that is outstanding to be canceled and (iii) in
consideration for such cancellation, and except to the extent that Tyco or the
Purchaser and the holder of any such Company Stock Option agree, cause the
Company (or, at Tyco's option, the Purchaser) to pay (net of applicable
withholding taxes) such holders of Company Stock Options an amount in respect
thereof equal to the product of (x) the excess, if any, of the Offer price over
the exercise price of each such Company Stock Option and (y) the number of
Shares subject to the Company Stock Option immediately prior to its
cancellation.
 
    EMPLOYMENT AND BENEFIT ARRANGEMENTS.  Tyco has agreed pursuant to the Merger
Agreement that, from and after the Effective Time, it shall cause the Surviving
Corporation to honor all employment, severance, termination and retirement
agreements to which the Company is a party, as such agreements are in effect on
the date of the Merger Agreement. Tyco has also agreed that, for a one-year
period following the Effective Time, it shall cause the Surviving Corporation to
provide those employees who are employees of the Surviving Corporation at the
Effective Time with benefits that are, in the aggregate, no less favorable to
such employees as are the benefits of the Company available to such employees
immediately prior to the Effective Time. These provisions are not intended,
however, to create rights of third party beneficiaries.
 
    INDEMNIFICATION AND INSURANCE.  In the Merger Agreement, Tyco and the
Purchaser have agreed that all rights to indemnification for acts or omissions
occurring prior to the effectiveness of the Merger that are in existence as of
the date of the Merger Agreement in favor of the current or former directors or
officers of the Company and its subsidiaries as provided in their respective
certificates or articles of incorporation or by-laws or contractual arrangements
shall survive the Merger and shall continue in full force and effect in
accordance with their terms. In addition, pursuant to the Merger Agreement, Tyco
has agreed to provide, or cause the Surviving Corporation to provide, for a
period of not less than six years after the Effective Time, the Company's
current directors and officers an insurance and indemnification policy that
provides coverage for events occurring at or prior to the Effective Time (the
"D&O Insurance") that is no less favorable than the Company's existing policy
or, if substantially equivalent insurance coverage is unavailable, the best
available coverage; PROVIDED, HOWEVER, that Tyco and the Surviving Corporation
will not be required to pay an annual premium for the D&O Insurance in excess of
200% of the annual premium currently paid by the Company for such insurance, but
in such case will purchase as much coverage as possible for such amount.
 
    REASONABLE EFFORTS.  The Merger Agreement provides that each of the parties
will use its reasonable efforts to take, or cause to be taken, all actions
necessary to comply promptly with all legal requirements which may be imposed on
itself with respect to the Offer and the Merger and will promptly cooperate with
and furnish information to each other in connection with any such requirements
imposed upon any of them or any of their subsidiaries in connection with the
Offer and the Merger and will, and will cause its subsidiaries to, use its
reasonable efforts to take all reasonable actions necessary to obtain (and will
cooperate with each other in obtaining) any consent, authorization, order or
approval of, or any exemption by, any Governmental Entity or other public or
private third party required to be obtained or made by any of them or any of
their subsidiaries in connection with the Offer and the Merger or the taking of
any action contemplated thereby or by the Merger Agreement, except that no party
need waive any substantial rights or agree to any substantial limitation on its
operations or to dispose of or hold separate any assets or otherwise take any
action that would require a waiver of, or that is inconsistent with the
satisfaction of, certain related conditions of the Offer set forth in the Merger
Agreement.
 
    AMENDMENT.  The Merger Agreement may be amended by the parties thereto, by
action taken or authorized by their respective Boards of Directors; PROVIDED,
HOWEVER, that after any approval of the Merger Agreement by the shareholders of
the Company, no amendment will be made to the Merger Agreement which by law
requires further approval by such shareholders without such further approval.
 
                                       23
<PAGE>
    SHAREHOLDER AGREEMENT
 
    As an inducement to Tyco and the Purchaser entering into the Merger
Agreement with the Company, shareholders owning approximately 61% (57% on a
fully diluted basis) of the Shares (each a "Shareholder") have entered into a
Shareholder Agreement (the "Shareholder Agreement") with Tyco and the Purchaser.
 
    The following summary of certain provisions of the Shareholder Agreement, a
copy of which is filed as an exhibit to the Schedule 14D-1, is qualified in its
entirety by reference to the text of the Shareholder Agreement.
 
    AGREEMENT TO TENDER.  Each Shareholder has agreed that it shall tender its
Shares (including Shares issuable upon the conversion of all Class B Common
Stock) in the Offer and that it shall not withdraw any Shares so tendered. In
connection therewith, the Company has agreed with, and covenanted to, Tyco that
the Company shall not register the transfer of any certificate representing any
Shareholder's Shares, unless such transfer is made to Tyco or the Purchaser or
otherwise in compliance with the Shareholder Agreement.
 
    GRANT OF IRREVOCABLE PROXY.  Each Shareholder has irrevocably granted to,
and appointed, Tyco and any individual designated by Tyco as such Shareholder's
proxy and attorney-in-fact, to vote such Shareholder's Shares, or grant a
consent or approval in respect of such Shares, at any meeting of shareholders of
the Company or in any other circumstances upon which such Shareholder's vote,
consent or other approval is sought, against (i) any merger agreement or merger
(other than the Merger Agreement and the Merger), consolidation, combination,
sale of substantial assets, reorganization, joint venture, recapitalization,
dissolution, liquidation or winding up of or by the Company and (ii) any
amendment of the Company's Articles of Incorporation or bylaws or other proposal
or transaction (including any consent solicitation to remove or elect any
directors of the Company) involving the Company or any of its subsidiaries,
which amendment or other proposal or transaction would in any manner impede,
frustrate, prevent or nullify, or result in a breach of any covenant,
representation or warranty or any other obligation or agreement of the Company
under or with respect to, the Offer, the Merger, the Merger Agreement or any of
the other transactions contemplated by the Merger Agreement.
 
    REPRESENTATIONS, WARRANTIES, COVENANTS AND OTHER AGREEMENTS.  Each
Shareholder has made certain representations and warranties in the Shareholder
Agreement, including with respect to (i) ownership of the Shares, (ii) the
authority to enter into and perform its obligations under the Shareholder
Agreement and the absence of required consents and statutory or contractual
conflicts or violations, (iii) the absence of liens, claims, security interests,
proxies, voting trusts or other arrangements or any other encumbrances on or in
respect of its Shares, (iv) finder's fees, and (v) an acknowledgement of Tyco's
reliance upon such Shareholder's execution of the Shareholder Agreement in
entering into, and causing the Purchaser to enter into, the Merger Agreement. In
addition, each Shareholder has agreed not to transfer, or consent to any
transfer of any or all of such Shareholder's Shares or any interest therein
(except as contemplated by the Shareholder Agreement), enter into any contract,
option or other agreement or understanding with respect to any transfer of any
or all of such Shares or any interest therein, grant any proxy,
power-of-attorney or other authorization or consent in or with respect to such
Shares or any interest therein, deposit such Shares into a voting trust or enter
into a voting arrangement or agreement with respect to such Shares or take any
other action that would in any way restrict, limit or interfere with its
obligations under the Shareholders Agreement. Each Shareholder has also agreed,
directly or indirectly, not to solicit, initiate or encourage the submission of
any Acquisition Proposal or participate in any discussions or negotiations
regarding, or furnish to any person any information with respect to, or take any
other action to facilitate any inquiries or the making of any proposal that
constitutes, or may reasonably be expected to lead to, any Acquisition Proposal.
 
                                       24
<PAGE>
    TERMINATION.  The Shareholder Agreement, and all rights and obligations
thereunder, shall terminate upon the earlier of (a) the termination of the
Merger Agreement in accordance with its terms either (i) by Tyco or the
Purchaser (provided that no termination under this clause shall relieve any
Shareholder of liability for such Shareholder's breach of its obligations under
the Shareholder Agreement) or (ii) by the mutual written consent of Tyco, the
Purchaser and the Company, or (b) the date that Tyco or the Purchaser shall have
purchased and paid for the Shares of each Shareholder pursuant to the terms of
the Shareholder Agreement.
 
    14.  DIVIDENDS AND DISTRIBUTIONS.
 
    The Merger Agreement provides that neither the Company nor any of its
subsidiaries will (x) declare or pay any dividends on, or make other
distributions in respect of, any of its capital stock, other than dividends by a
direct or indirect wholly-owned subsidiary of the Company to its parent, (y)
split, combine or reclassify any of its capital stock or issue or authorize or
propose the issuance of any other securities in respect of, in lieu of or in
substitution for shares of its capital stock, or (z) repurchase, redeem or
otherwise acquire any shares of capital stock of the Company or any of its
subsidiaries or any other securities thereof.
 
    If on or after the date of the Merger Agreement and notwithstanding the
provisions thereof, the Company should (i) split, combine or otherwise change
the Shares or its capitalization, (ii) acquire presently outstanding Shares or
otherwise cause a reduction in the number of outstanding Shares, or (iii) issue
or sell any shares of any class or any securities convertible into any such
shares, or any rights, warrants or options to acquire any such shares or
convertible securities (other than Shares issued pursuant to, and in accordance
with the terms in effect on the date of the Merger Agreement of, stock options
issued prior to such date), then, without prejudice to the Purchaser's rights
under the Merger Agreement, the Purchaser (subject to the Merger Agreement), in
its sole discretion, may make such adjustments in the Offer price and other
terms of the Offer as it deems appropriate to reflect such action.
 
    If, on or after the date of the Merger Agreement and notwithstanding the
provisions thereof, the Company should declare or pay any cash, non-cash or
stock dividend or other distribution on, or issue any rights with respect to,
the Shares, payable or distributable to shareholders of record on a date prior
to the transfer to the name of the Purchaser or its nominees or transferees on
the Company's stock transfer records of the Shares purchased pursuant to the
Offer, then, without prejudice to the Purchaser's rights under the Merger
Agreement, (i) the price per Share payable by the Purchaser pursuant to the
Offer may (subject to the Merger Agreement), in the sole discretion of the
Purchaser, be reduced by the amount of any such cash dividend or distribution,
and (ii) any non-cash dividend, distribution or right to be received by the
tendering shareholders will (a) be received and held by the tendering
shareholders for the account of the Purchaser and will be required to be
promptly remitted and transferred by each tendering shareholder to the
Depositary for the account of the Purchaser, accompanied by appropriate
documentation of transfer, or (b) at the direction of the Purchaser, be
exercised for the benefit of the Purchaser, in which case the proceeds of such
exercise will promptly be remitted to the Purchaser. Pending such remittance,
the Purchaser will be, subject to applicable law, entitled to all rights and
privileges as owner of any such non-cash dividend, distribution or right or such
proceeds and may withhold the entire purchase price or deduct from the purchase
price the amount or value thereof, as determined by the Purchaser in its sole
discretion.
 
    15.  CERTAIN CONDITIONS OF THE OFFER. Notwithstanding any other term of the
Offer or the Merger Agreement, the Purchaser shall not be required to accept for
payment or pay for, subject to any applicable rules and regulations of the
Commission, including Rule 14e-1(c) of the Exchange Act, any Shares not
theretofore accepted for payment or paid for and may terminate or amend the
Offer as to such Shares, unless (i) there shall have been validly tendered and
not withdrawn prior to the expiration of the Offer that number of Shares which
would represent at least a majority of the outstanding Shares on a fully diluted
basis (the "Minimum Condition"), and (ii) any waiting period under the HSR Act
applicable to the
 
                                       25
<PAGE>
purchase of Shares pursuant to the Offer shall have expired or been terminated.
Furthermore, notwithstanding any other term of the Offer or the Merger
Agreement, the Purchaser shall not be required to accept for payment or, subject
as aforesaid, to pay for any Shares not theretofore accepted for payment or paid
for, and may terminate or amend the Offer, if at any time on or after the date
of the Merger Agreement and before the acceptance of such Shares for payment or
the payment therefor, any of the following conditions exist or shall occur and
remain in effect:
 
        (a) there shall have been instituted, pending or threatened any action
    or proceeding by any court or other Governmental Entity, which (i) seeks to
    challenge the acquisition by Tyco or the Purchaser (or any of its
    affiliates) of Shares pursuant to the Offer, restrain or prohibit the making
    or consummation of the Offer or the Merger, or obtain damages in connection
    therewith in an amount which would reasonably be expected to have a material
    adverse effect, (ii) seeks to make the purchase of or payment for some or
    all of the Shares pursuant to the Offer or the Merger illegal, (iii) seeks
    to impose limitations on the ability of Tyco (or any of its affiliates)

    their respective affiliates or subsidiaries to dispose of or hold separate,
    any portion of the assets or the business of Tyco and its affiliates or any
    material portion of the assets or the business of the Company and its
    subsidiaries taken as a whole, as a result of the Offer or the Merger or
    (iv) seeks to impose material limitations on the ability of Tyco (or its
    affiliates) to exercise full rights of ownership of the Shares purchased by
    it, including, without limitation, the right to vote the Shares purchased by
    it on all matters properly presented to the shareholders of the Company; or
 
        (b) there shall have been promulgated, enacted, entered, enforced or
    deemed applicable to the Offer or the Merger, by any statute, rule,
    regulation, judgment, decree, order or injunction, other than the
    application of waiting periods under the HSR Act, that is reasonably likely
    to directly or indirectly result in any of the consequences referred to in
    clauses (i) through (iv) of subsection (a) above; or
 
        (c) (A) the representations and warranties of the Company with respect
    to capitalization shall not have been true and correct in all material
    respect when made, or shall thereafter have ceased to be true and correct in
    all material respects as if made as of such later date (other than
    representations and warranties made as of a specified date) or (B) the
    representations and warranties made by the Company in the Merger Agreement
    shall not have been true and correct in all material respects when made, or
    shall thereafter have ceased to be true and correct in all material respects
    as if made as of such later date (other than representations and warranties
    made as of a specified date), except in any case where such failure to be
    true and correct would not, in the aggregate, have a material adverse effect
    or prevent or materially delay the consummation of the Offer and/or the
    Merger; or
 
        (d) the Company shall not in all material respects have performed in a
    timely manner any material obligation and agreement and complied with any
    material covenant to be performed and complied with by it under the Merger
    Agreement; or
 
        (e) (i) the Board of Directors of the Company shall have failed to

    or be threatened (other than any affecting the electronics industry
    generally) that would reasonably be expected to have a material adverse
    effect on the Company; or
 
        (g) the Company shall commence a case under any chapter of Title XI of
    the United States Code or any similar law or regulation; or a petition under
    any chapter of Title XI of the United States
 
                                       26

    Code or any similar law or regulation is filed against the Company which is
    not dismissed within five business days; or
 
        (h) the Merger Agreement shall have been terminated in accordance with
    its terms.
 
    The foregoing conditions are for the sole benefit of Tyco and the Purchaser
except as otherwise provided in the Merger Agreement and may be asserted by Tyco
or the Purchaser regardless of the circumstances giving rise to any such
condition and may be waived by Tyco or the Purchaser, in whole or in part, at
any time and from time to time, in the sole discretion of Tyco. The failure by
Tyco or the Purchaser at any time to exercise any of the foregoing rights will
not be deemed a waiver of any right, the waiver of such right with respect to
any particular facts or circumstances shall not be deemed a waiver with respect
to any other facts or circumstances, and each right will be deemed an ongoing
right which may be asserted at any time and from time to time.
 
    Should the Offer be terminated pursuant to the foregoing provisions, all
tendered Shares not theretofore accepted for payment shall forthwith be returned
by the Depositary to the tendering shareholders.
 
    16.  CERTAIN LEGAL MATTERS.
 
    GENERAL.  Except as described in this Section 16, based on a review of
publicly available filings by the Company with the Commission and other publicly
available information concerning the Company, neither Tyco nor the Purchaser is
aware of any license or regulatory permit that appears to be material to the
business of the Company and that might be adversely affected by the Purchaser's
acquisition of Shares pursuant to the Offer, or of any approval or other action
by any governmental, administrative or regulatory agency or authority, domestic
or foreign, that would be required for the acquisition or ownership of Shares by
the Purchaser pursuant to the Offer. Should any such approval or other action be
required, it is presently contemplated that such approval or action would be
sought, except as described below under "State Takeover Laws." While the
Purchaser does not currently intend to delay acceptance for payment of Shares
tendered pursuant to the Offer pending the outcome of any such matter, there can
be no assurance that any such approval or other action, if required, would be
obtained without substantial conditions or that adverse consequences would not
result to the Company's business or that certain parts of the Company's business
would not have to be disposed of in the event that such approvals were not
obtained or such other actions were not taken or in order to obtain any such
approval or other action. If certain types of adverse action are taken with
respect to the matters discussed below, the Purchaser may decline to accept for
payment or pay for any Shares tendered. See Section 15.
 
    STATE TAKEOVER LAWS.  The Company and certain of its subsidiaries conduct
business in a number of states throughout the United States, some of which have
adopted laws and regulations applicable to offers to acquire shares of
corporations that are incorporated or have substantial assets, shareholders
and/or a principal place of business in such states. In Edgar v. MITE Corp., the
Supreme Court of the United States held that the Illinois Business Takeover
Statute, which involved state securities laws that made the takeover of certain
corporations more difficult, imposed a substantial burden on interstate commerce
and was therefore unconstitutional. In CTS Corp. v. Dynamics Corp. of America,
however, the Supreme Court of the United States held that a state may, as a
matter of corporate law and, in particular, those laws concerning corporate
governance, constitutionally disqualify a potential acquiror from voting on the
affairs of a target corporation without prior approval of the remaining
shareholders, provided that such laws were applicable only under certain
conditions, in particular, that the corporation has a substantial number of
shareholders in and is incorporated under the laws of such state.
 
    The Company is incorporated under the laws of the State of Florida. Section
607.0901 of the FBCA (the "Affiliated Transactions Statute") prohibits certain
"affiliated transactions" (defined to include mergers and consolidations)
involving a Florida corporation and an "interested shareholder" (defined
generally as a person who is the beneficial owner of more than 10% of the
outstanding voting shares of the
 
                                       27
<PAGE>
subject corporation) unless the transaction has been approved by (i) a majority
of "disinterested directors" of the subject corporation (defined generally as
directors who were elected to the board prior to the time the shareholder became
an interested shareholder), (ii) holders of two-thirds of the outstanding voting
shares of the subject corporation, exclusive of those shares beneficially owned
by the shareholder who, but for such approval, would be an "interested
shareholder" or (iii) certain other statutory conditions have been met. At a
meeting held on November 27, 1996, the Board of Directors of the Company
approved the Merger Agreement, the Merger and the transactions contemplated
thereby (collectively, the "Merger Transaction") and determined that each of the
Offer and the Merger are fair to, and in the best interest of, the Company's
shareholders. Accordingly, the Affiliated Transactions Statute is inapplicable
to the Merger.
 
    Section 607.0902 of the FBCA (the "Control Share Acquisitions Statute")
limits, in certain circumstances, the voting rights of "control shares" (defined
generally as those shares of an issuing public corporation which, when added to
the number of shares of the corporation already owned or controlled by a person,
entitle that person, immediately after the acquisition of the shares, to
exercise, directly or indirectly, alone or as part of a group, at least
one-fifth of the voting power of the corporation in the election of directors)
acquired in a "control share acquisition" (defined generally to mean the
acquisition directly or indirectly by any person of ownership of, where the
person is to direct the exercise of, voting power with respect to issued and
outstanding control shares) unless the acquisition of the control shares of an
issuing public corporation has been approved by the board of directors of such
issuing public corporation or certain other statutory conditions have been met.
At a meeting held on November 27, 1996, the Board of Directors of the Company
approved the acquisition of the Shares pursuant to the Offer and the Merger.
Accordingly, the Control Share Acquisition Statute is inapplicable to Tyco and
the Purchaser in connection with the Offer and the Merger.
 
    Neither Tyco nor the Purchaser has determined whether any other state
takeover laws and regulations will by their terms apply to the Offer, and,
except as set forth above, neither Tyco nor the Purchaser has presently sought
to comply with any state takeover statute or regulation. Tyco and the Purchaser
reserve the right to challenge the applicability or validity of any state law or
regulation purporting to apply to the Offer or the Merger, and neither anything
in this Offer nor any action taken in connection herewith is intended as a
waiver of such right. In the event it is asserted that one or more state
takeover statutes is applicable to the Offer or the Merger and an appropriate
court does not determine that such statute is inapplicable or invalid as applied
to the Offer or the Merger, Tyco or the Purchaser might be required to file
certain information with, or to receive approval from, the relevant state
authorities, and the Purchaser might be unable to accept for payment or pay for
Shares tendered pursuant to the Offer, or be delayed in consummating the Offer.
 
    ANTITRUST.  Under the HSR Act and the rules that have been promulgated
thereunder by the Federal Trade Commission (the "FTC"), certain acquisition
transactions may not be consummated unless certain information has been
furnished to the Antitrust Division of the U.S. Department of Justice (the
"Antitrust Division") and the FTC and certain waiting period requirements have
been satisfied. The acquisition of Shares by the Purchaser pursuant to the Offer
is subject to such requirements. See Section 15.
 
    Under the provisions of the HSR Act applicable to the purchase of Shares
pursuant to the Offer, purchases may not be consummated until the expiration of
a 15-calendar day waiting period after the filing of certain required
information and documentary material with the Antitrust Division and the FTC
with respect to the Offer (unless earlier terminated pursuant to a request
therefor, which Tyco will make). If, within such 15-day waiting period, either
the Antitrust Division or the FTC requests additional information or documentary
material relevant to the Offer from Tyco, the waiting period will be extended
for an additional period of 10 calendar days following the date of substantial
compliance with such request. Only one extension of the waiting period pursuant
to a request for additional information is authorized by the rules promulgated
under the HSR Act. Thereafter, such waiting period may be extended only by court
order or by agreement of Tyco. A request for additional information issued to
the Company cannot extend
 
                                       28
<PAGE>
the waiting period. Tyco expects to file, or cause to be filed, a Notification
and Report Form with respect to the Offer under the HSR Act on December 9, 1996,
and, in such event, the required waiting period with respect to the Offer will
expire at 11:59 p.m., New York City time, on December 23, 1996, unless Tyco
receives a request for additional information or documentary material or the
Antitrust Division or the FTC terminates the waiting period prior thereto.
 
    The Antitrust Division and the FTC frequently scrutinize the legality under
the antitrust laws of transactions such as the proposed purchase of Shares by
the Purchaser pursuant to the Offer. At any time before or after such purchase,
the Antitrust Division or the FTC could take such action under the antitrust
laws as it deems necessary or desirable in the public interest, including
seeking to enjoin the transaction or seeking divestiture of the Shares so
acquired or divestiture of substantial assets of Tyco or its subsidiaries.
Litigation seeking similar relief could also be brought by private persons and
the state attorneys general.
 
    Based upon an examination of publicly available information relating to the
businesses in which Tyco and the Company are engaged, Tyco and the Purchaser do
not believe that consummation of the Offer will result in violation of any
applicable antitrust laws. However, there can be no assurance that a challenge
to the Offer on antitrust grounds will not be made, or, if such a challenge is
made, what the result would be. See Section 15 for certain conditions to the
Offer, including conditions with respect to litigation and certain governmental
actions.
 
    17.  FEES AND EXPENSES.  The Purchaser has retained MacKenzie Partners, Inc.
to act as the Information Agent and ChaseMellon Shareholder Services, L.L.C. to
act as the Depositary in connection with the Offer. The Information Agent may
contact holders of Shares by mail, telephone, telex, telecopy and personal
interview and may request brokers, dealers and other nominee shareholders to
forward the Offer materials to beneficial owners. The Information Agent and the
Depositary will receive reasonable and customary compensation for services
relating to the Offer and will be reimbursed for certain out-of-pocket expenses.
The Purchaser and Tyco have also agreed to indemnify the Information Agent and
the Depositary against certain liabilities and expenses in connection with the
Offer, including certain liabilities under the federal securities laws.
 
    Neither Tyco nor the Purchaser will pay any fees or commissions to any
broker or dealer or any other person (other than to the Information Agent) for
soliciting tenders of Shares pursuant to the Offer. Brokers, dealers, commercial
banks and trust companies will, upon request, be reimbursed by the Purchaser for
customary mailing and handling expenses incurred by them in forwarding offering
materials to their customers.
 
    18.  MISCELLANEOUS.  The Offer is being made to all holders of Shares. The
Purchaser is not aware of any jurisdiction where the making of the Offer is
prohibited by administrative or judicial action pursuant to any valid state
statute. If the Purchaser becomes aware of any valid state statute prohibiting
the making of the Offer or the acceptance of Shares pursuant thereto, the
Purchaser will make a good faith effort to comply with any such state statute or
seek to have such statute declared inapplicable to the Offer. If, after such
good faith effort, the Purchaser cannot comply with any such state statute, the
Offer will not be made to (nor will tenders be accepted from or on behalf of)
the holders of Shares in such state. In any jurisdiction where the securities,
blue sky or other laws require the Offer to be made by a licensed broker or
dealer, the Offer will be deemed to be made on behalf of the Purchaser by one or
more registered brokers or dealers licensed under the laws of such jurisdiction.
 
    No person has been authorized to give any information or make any
representation on behalf of Tyco, the Purchaser or the Company not contained in
this Offer to Purchase or in the related Letter of Transmittal and, if given or
made, such information or representation must not be relied upon as having been
authorized.
 
                                       29
<PAGE>
    Tyco and the Purchaser have filed with the Commission a Tender Offer
Statement on Schedule 14D-1, together with all exhibits thereto, pursuant to
Rule 14d-3 of the General Rules and Regulations under the Exchange Act,
furnishing certain additional information with respect to the Offer. Such Tender
Offer Statement and any amendments thereto, including exhibits, may be inspected
and copies may be obtained from the offices of the Commission in the manner set
forth in Section 8 (except that they will not be available at the regional
offices of the Commission).

other Shares or securities or rights), or transfer ownership of such Shares (and
any such other Shares or securities or rights) on the account books maintained

                                  INSTRUCTIONS
             FORMING PART OF THE TERMS AND CONDITIONS OF THE OFFER
 
    1.  GUARANTEE OF SIGNATURES.  No signature guarantee on this Letter of
Transmittal is required (i) if this Letter of Transmittal is signed by the
registered holder(s) of the Shares (which term, for purposes of this document,
shall include any participant in a Book-Entry Transfer Facility whose name
appears on a security position listing as the owner of Shares) tendered
herewith, unless such holder has completed either the box entitled "Special
Delivery Instructions" or the box entitled "Special Payment Instructions" on
this Letter of Transmittal, or (ii) if such Shares are tendered for the account
of a firm that is a member in good standing of the Security Transfer Agent's
Medallion Program, the New York Stock Exchange Medallion Signature Program or
the Stock Exchange Medallion Program (each being hereinafter referred to as an
"Eligible Institution"). In all other cases, all signatures on this Letter of
Transmittal must be guaranteed by an Eligible Institution. See Instruction 5.
 
    2.  DELIVERY OF LETTER OF TRANSMITTAL AND CERTIFICATES.  This Letter of
Transmittal is to be completed by shareholders either if certificates
representing Shares are to be forwarded herewith to the Depositary or, unless an
Agent's Message (as defined below) is utilized, if tenders of Shares are to be
made pursuant to the procedures for delivery by book-entry transfer set forth in
Section 2 of the Offer to Purchase. Certificates representing all physically
tendered Shares, or any book-entry confirmation of Shares, as the case may be,
together with a properly completed and duly executed Letter of Transmittal (or
facsimile thereof), with any required signature guarantees, or, in connection
with a book-entry transfer, an Agent's Message, and any other documents required
by this Letter of Transmittal, must be received by the Depositary at one of its
addresses set forth herein on or prior to the Expiration Date (as defined in
Section 1 of the Offer to Purchase). If a shareholder's certificate(s)
representing Shares are not immediately available (or the procedure for the
book-entry transfer cannot be completed on a timely basis) or time will not
permit all required documents to reach the Depositary on or prior to the
Expiration Date, such shareholder's Shares may nevertheless be tendered if the
procedures for guaranteed delivery set forth in Section 2 of the Offer to
Purchase are followed. Pursuant to such procedure, (i) such tender must be made
by or through an Eligible Institution, (ii) a properly completed and duly
executed Notice of Guaranteed Delivery, substantially in the form provided by
the Purchaser, must be received by the Depositary on or prior to the Expiration
Date, and (iii) the certificates representing all tendered Shares, in proper
form for transfer, or Book-Entry Confirmation of Shares, as the case may be, in
each case together with a properly completed and duly executed Letter of
Transmittal (or facsimile thereof), with any required signature guarantees (or,
in connection with a book-entry transfer, an Agent's Message) and any other
documents required by this Letter of Transmittal, must be received by the
Depositary within three Nasdaq Stock Market's National Market trading days after
the date of execution of such Notice of Guaranteed Delivery, all as provided in
Section 2 of the Offer to Purchase. The term "Agent's Message" means a message
transmitted through electronic means by a Book-Entry Transfer Facility to, and
received by, the Depositary and forming a part of a book-entry confirmation,
which states that such Book-Entry Transfer Facility has received an express
acknowledgment from the participant in such Book-Entry Transfer Facility
tendering the Shares that such participant has received, and agrees to be bound
by, this Letter of Transmittal.
 
    The method of delivery of this Letter of Transmittal, the certificate(s)
representing Shares and all other required documents, including delivery through
a Book-Entry Transfer Facility, is at the option and sole risk of the tendering
shareholder. The delivery will be deemed made only when actually received by the
Depositary. If such delivery is by mail, registered mail with return receipt
requested, properly insured, is recommended. In all cases, sufficient time
should be allowed to insure timely delivery.
 
    No alternative, conditional or contingent tenders will be accepted, and no
fractional Shares will be purchased. All tendering shareholders, by execution of
this Letter of Transmittal (or facsimile thereof), waive any right to receive
any notice of the acceptance of their Shares for payment.
 
    3.  INADEQUATE SPACE.  If the space provided herein is inadequate, the
certificate numbers and/ or the number of Shares should be listed on a separate
signed schedule attached hereto.
<PAGE>
    4.  PARTIAL TENDERS (not applicable to shareholders who tender Shares by
book-entry transfer).  If fewer than all the Shares represented by any
certificate submitted are to be tendered, fill in the number of Shares that are
to be tendered in the box entitled "Number of Shares Tendered." In such case,
new certificate(s) representing the remainder of the Shares that were
represented by the old certificate(s) will be sent to the registered holder(s),
unless otherwise provided in the appropriate box on this Letter of Transmittal,
as soon as practicable after the Expiration Date. All Shares represented by
certificate(s) delivered to the Depositary will be deemed to have been tendered
unless otherwise indicated.
 
    5.  SIGNATURES ON LETTER OF TRANSMITTAL, STOCK POWERS AND ENDORSEMENTS.  If
this Letter of Transmittal is signed by the registered holder(s) of the Shares
tendered hereby, the signature(s) must correspond exactly with the name(s) as
written on the face(s) of the certificate(s) without alteration, enlargement or
any change whatsoever.
 
    If any of the Shares tendered hereby are owned of record by two or more
joint owners, all such owners must sign this Letter of Transmittal.
 
    If any tendered Shares are registered in different names on several
certificates, it will be necessary to complete, sign and submit as many separate
Letters of Transmittal as there are different registrations of certificates.
 
    If this Letter of Transmittal is signed by the registered holder(s) of the
Shares listed and tendered hereby, no endorsements of certificates or separate
stock powers are required, unless payment or certificates for Shares not
tendered or accepted for payment are to be issued to a person other than the
registered holder(s). Signatures on such certificates or stock powers must be
guaranteed by an Eligible Institution.
 
    If this Letter of Transmittal or any certificates or stock powers are signed
by a trustee, executor, administrator, guardian, attorney-in-fact, officer of a
corporation or other person acting in a fiduciary or representative capacity,
such person should so indicate when signing, and proper evidence satisfactory to
the Purchaser of such person's authority so to act must be submitted.
 
    If this Letter of Transmittal is signed by a person other than the
registered holder(s) of the Shares tendered hereby, the certificates must be
endorsed or accompanied by appropriate stock powers, in either case signed
exactly as the name(s) of the registered holder(s) appear on the certificates.
Signatures on such certificates or stock powers must be guaranteed by an
Eligible Institution, unless the signature is that of an Eligible Institution.
 
    6.  STOCK TRANSFER TAXES.  Except as set forth in this Instruction 6, the
Purchaser will pay or cause to be paid any stock transfer taxes with respect to
the transfer and sale of purchased Shares to it or its order pursuant to the
Offer. If, however, payment of the purchase price is to be made to, or if
certificates representing Shares not tendered or accepted for payment are to be
registered in the name of, any person other than the registered holder, or if
tendered certificates are registered in the name of any person other than the
person(s) signing this Letter of Transmittal, the amount of any stock transfer
taxes (whether imposed on the registered holder or such other person) payable on
account of the transfer to such person will be deducted from the purchase price,
unless satisfactory evidence of the payment of such taxes or exemption therefrom
is submitted.
 
    7.  SPECIAL PAYMENT AND DELIVERY INSTRUCTIONS.  If a check and/or
certificates representing Shares not tendered or accepted for payment are to be
issued in the name of a person other than the signer of this Letter of
Transmittal or if a check is to be sent and/or such certificates are to be
returned to someone other than the signer of this Letter of Transmittal or to an
address other than that shown above, the appropriate boxes on this Letter of
Transmittal should be completed. Shareholders tendering Shares by book-entry
transfer may request that Shares not accepted for payment be credited to such
account maintained at a Book-Entry Transfer Facility as such shareholder may
designate hereon. If no such instructions are given, such Shares not accepted
for payment will be returned by crediting the account at the Book-Entry Transfer
Facility designated above.
<PAGE>
    8.  LOST, DESTROYED OR STOLEN CERTIFICATES.  If any certificate(s)
representing Shares has been lost, destroyed or stolen, the shareholder should
promptly notify the Depositary. The shareholder will then be instructed as to
the steps that must be taken in order to replace the certificate(s). This Letter
of Transmittal and related documents cannot be processed until the procedures
for replacing lost or destroyed certificates have been followed.
 
    9.  WAIVER OF CONDITIONS.  The conditions of the Offer may be waived by the
Purchaser, in whole or in part, at any time and from time to time in the
Purchaser's sole discretion, in the case of any Shares tendered hereby.
 
    10.  SUBSTITUTE FORM W-9.  The tendering shareholder is required to provide
the Depositary with a correct Taxpayer Identification Number ("TIN"), generally
the shareholder's social security or federal employer's identification number,
on Substitute Form W-9, which is provided below, and to certify whether the
shareholder is subject to backup withholding of Federal income tax. If a
tendering shareholder is subject to backup withholding, the shareholder must
cross out item (2) of the Certification box of the Substitute Form W-9. Failure
to provide the information on the Substitute Form W-9 may subject the tendering
shareholder to 31% Federal income tax withholding on the payment of the purchase
price. If the tendering shareholder has not been issued a TIN and has applied
for a number or intends to apply for a number in the near future, he or she
should write "Applied For" in the space provided for the TIN in Part I, and sign
and date the Substitute Form W-9. If "Applied For" is written in Part I and the
Depositary is not provided with a TIN within 60 days, the Depositary will
withhold 31% on all payments of the purchase price until a TIN is provided to
the Depositary.
 
    11.  FOREIGN HOLDERS.  Foreign holders must submit a completed IRS Form W-8
to avoid backup withholding. IRS Form W-8 may be obtained by contacting the
Depositary at one of the addresses on the face of this Letter of Transmittal.
 
    12.  REQUESTS FOR ASSISTANCE OR ADDITIONAL COPIES.  Requests for assistance
may be directed to the Information Agent at the address set forth below.
Additional copies of the Offer to Purchase, this Letter of Transmittal, the
Notice of Guaranteed Delivery and the Guidelines for Certification of Taxpayer
Identification Number on Substitute Form W-9 may be obtained from the
Information Agent at the address set forth below or from your broker, dealer,
commercial bank or trust company.
 
    IMPORTANT:  This Letter of Transmittal (or a facsimile thereof), together
with certificates representing Shares or confirmation of book-entry transfer and
all other required documents, or the Notice of Guaranteed Delivery, must be
received by the Depositary on or prior to the Expiration Date.
 
                           IMPORTANT TAX INFORMATION
 
    Under Federal income tax law, a shareholder whose tendered Shares are
accepted for payment is required to provide the Depositary (as payer) with such
shareholder's correct TIN on Substitute Form W-9 below. If such shareholder is
an individual, the TIN is his social security number. If a tendering shareholder
is subject to backup withholding, he must cross out item (2) of the
Certification box on the Substitute Form W-9. If the Depositary is not provided
with the correct TIN, the shareholder may be subject to a $50 penalty imposed by
the Internal Revenue Service ("IRS"). In addition, payments that are made to
such shareholder with respect to Shares purchased pursuant to the Offer may be
subject to backup withholding.
 
    Certain shareholders (including, among others, all corporations and certain
foreign individuals) are not subject to these backup withholding and reporting
requirements. In order for a foreign individual to qualify as an exempt
recipient, that shareholder must submit to the Depositary a properly completed
IRS Form W-8, signed under penalties of perjury, attesting to that individual's
exempt status. Such statements may be obtained from the Depositary. Exempt
shareholders, other than foreign individuals, should furnish their TIN, write
"Exempt" on the face of the Substitute Form W-9 below, and sign, date and return
the Substitute Form W-9 to the Depositary. See the enclosed Guidelines for
Certification of Taxpayer Identification Number on Substitute Form W-9 for
additional instructions.
<PAGE>
    If backup withholding applies, the Depositary is required to withhold 31% of
any payments made to the shareholder. Backup withholding is not an additional
tax. Rather, the tax liability of persons subject to backup withholding will be
reduced by the amount of tax withheld. If withholding results in an overpayment
of taxes, a refund may be obtained from the IRS.
 
PURPOSE OF SUBSTITUTE FORM W-9
 
    To prevent backup withholding on payments that are made to a shareholder
with respect to Shares purchased pursuant to the Offer, the shareholder is
required to notify the Depositary of his correct TIN by completing the
Substitute Form W-9 below certifying that the TIN provided on such form is
correct (or that such shareholder is awaiting a TIN) and that (i) such holder is
exempt from backup withholding, (ii) such holder has not been notified by the
IRS that he is subject to backup withholding as a result of a failure to report
all interest or dividends, or (iii) the IRS has notified such holder that he is
no longer subject to backup withholding (see Part II of Substitute Form W-9).
 
WHAT NUMBER TO GIVE THE DEPOSITARY
 
    The shareholder is required to give the Depositary the social security
number or employer identification number of the record owner of the Shares. If
the Shares are in more than one name or are not in the name of the actual owner,
consult the enclosed Guidelines for Certification of Taxpayer Identification
Number on Substitute Form W-9 for additional guidelines on which number to
report. If the tendering shareholder has not been issued a TIN and has applied
for a number or intends to apply for a number in the near future, he should
write "Applied For" in the space provided for in the TIN in Part I, and sign and
date the Substitute Form W-9. If "Applied For" is written in Part I and the
Depositary is not provided with a TIN within 60 days, the Depositary will
withhold 31% on all payments of the purchase price until a TIN is provided to
the Depositary.

                        (2) I am not subject to backup withholding either because (a) I am
                        exempt from backup withholding, (b) I have not been notified by the
                            IRS that I am subject to backup withholding as a result of a

into rapidly growing market segments and enlarge our mutual customer base. 
Additionally, the ElectroStar acquisition strengthens our quick-turn service 
capability," said L. Dennis Kozlowski, Tyco's Chairman and Chief Executive 
Officer. Mr. Kozlowski also noted that the acquisition would provide an 
immediate positive contribution to Tyco's earnings.

                               TYCO INTERNATIONAL LTD.


         T3 Acquisition Corp., a Florida corporation (the "Purchaser") and a 
wholly owned subsidiary of Tyco International Ltd., a Massachusetts 
corporation ("Tyco"), is offering to purchase all outstanding shares of 
common stock, par value $.01 per share (the "Shares"), of ElectroStar, Inc., 
a Florida corporation (the "Company"), at $14.00 per Share, net to the seller 
in cash (the "Offer Price"), upon the terms and subject to the conditions set 
forth in the Offer to Purchase dated December 5, 1996 and in the related 
Letter of Transmittal (which together constitute the "Offer").

         THE OFFER AND WITHDRAWAL RIGHTS WILL EXPIRE AT 12:00 MIDNIGHT, NEW
         YORK CITY TIME, ON FRIDAY, JANUARY 3, 1997, UNLESS EXTENDED.

         The Offer is conditioned upon, among other things, there being 
validly tendered and not withdrawn prior to the expiration of the Offer at 
least that number of Shares which would constitute a majority of the 
outstanding Shares on a fully diluted basis (the "Minimum Condition"). 
Beneficial owners of approximately 61% (57% on a fully diluted basis) of the 
total


<PAGE>


number of outstanding shares have agreed to tender all of their shares 
pursuant to the Offer.

         The Offer is being made pursuant to an Agreement and Plan of Merger, 
dated as of November 27, 1996 (the "Merger Agreement"), among Tyco, the 
Purchaser and the Company pursuant to which, following the consummation of 
the Offer and the satisfaction or waiver of certain conditions, the Purchaser 
will be merged with and into the Company (the "Merger").  At the effective 
time of the Merger, each outstanding Share (other than Shares held in the 
Company's treasury or by any wholly owned subsidiary of the Company, or owned 
by Tyco, the Purchaser or any other wholly owned subsidiary of Tyco or held 
by shareholders, if any, who are entitled to and who properly exercise 
dissenters' rights under Florida law) will be converted into the right to 
receive the Offer Price, without interest.

         The Board of Directors of the Company has determined that the Offer 
and the Merger are fair to, and in the best interests of, the Company and its 
shareholders, has approved the Merger Agreement, the Offer and the Merger, 
and recommends that the Company's shareholders accept the Offer and tender 
their Shares pursuant to the Offer.

         For purposes of the Offer, the Purchaser will be deemed to have 
accepted for payment, and thereby purchased, Shares properly tendered to the 
Purchaser and not withdrawn as, if and when the Purchaser gives oral or 
written notice to ChaseMellon Shareholder Services, L.L.C. (the "Depositary") 
of the Purchaser's acceptance for payment of such Shares.  Upon the terms and 
subject to the conditions of the Offer, payment for Shares purchased pursuant 
to the Offer will be made by deposit of the purchase price therefor with the 
Depositary, which will act as agent for tendering shareholders for the 
purpose of receiving payment from the Purchaser and transmitting payment to 
tendering shareholders.  In all cases, payment for Shares purchased pursuant 
to the Offer will be made only after timely receipt by the Depositary of (a) 
certificates for such Shares or timely confirmation of book-entry transfer of 
such Shares into the Depositary's account at a Book-Entry Transfer Facility 
(as defined in the Offer to Purchase) pursuant to the procedures set forth in 
Section 2 of the Offer to Purchase, (b) a properly completed and duly 
executed Letter of Transmittal (or facsimile thereof) with any required 
signature guarantees or an Agent's Message (as defined in the Offer to 
Purchase) in connection with a book-entry transfer, and (c) any other documents
required by the Letter of Transmittal.  Under no circumstances will interest be
paid by the Purchaser on the purchase price of the Shares, regardless of any 
delay in making such payment.

         The term "Expiration Date" means 12:00 Midnight, New York City time,
on Friday, January 3, 1997, unless and until the Purchaser, in its sole
discretion (but subject to the terms of the Merger Agreement), shall have
extended the period of time during which the Offer is open, in which event the
term

                                          -2-


<PAGE>

"Expiration Date" shall mean the latest time and date at which the Offer, as 
so extended by the Purchaser, shall expire.  The Purchaser expressly reserves 
the right, in its sole discretion (but subject to the terms of the Merger 
Agreement), at any time or from time to time, and regardless of whether or 
not any of the events set forth in Section 15 of the Offer to Purchase shall 
have occurred or shall have been determined by the Purchaser to have 
occurred, to extend the period of time during which the Offer is open and 
thereby delay acceptance for payment of, and the payment for, any Shares, by 
giving oral or written notice of such extension to the Depositary.  The 
Purchaser shall not have any obligation to pay interest on the purchase price 
for tendered Shares in the event the Purchaser exercises its right to extend 
the period of time during which the Offer is open.  There can be no assurance 
that the Purchaser will exercise its right to extend the Offer.  Any such 
extension will be followed by a public announcement thereof no later than 
9:00 A.M., New York City time, on the next business day after the previously 
scheduled Expiration Date.  During any such extension, all Shares previously 
tendered and not withdrawn will remain subject to the Offer, subject to the 
right of a tendering shareholder to withdraw such shareholder's Shares.  

         Except as otherwise provided below, tenders of Shares are 
irrevocable.  Shares tendered pursuant to the Offer may be withdrawn at any 
time prior to 12:00 Midnight, New York City time, on Friday, January 3, 1997 
(or, if the Purchaser shall have extended the period of time during which the 
Offer is open, the latest time and date at which the Offer, as so extended by 
the Purchaser, shall expire) and, unless theretofore accepted for payment and 
paid for by the Purchaser pursuant to the Offer, may also be withdrawn at any 
time on or after February 4, 1997.  For a withdrawal to be effective, a 
written, telegraphic or facsimile transmission notice of withdrawal must be 
timely received by the Depositary at one of its addresses set forth on the 
back cover of the Offer to Purchase and must specify the name of the person 
having tendered the Shares to be withdrawn, the number of Shares to be 
withdrawn and the name of the registered holder of the Shares to be 
withdrawn, if different from the name of the person who tendered the Shares.  
If certificates for Shares have been delivered or otherwise identified to the 
Depositary, then, prior to the physical release of such certificates, the 
serial numbers shown on such certificates must be submitted to the Depositary 
and, unless such Shares have been tendered by an Eligible Institution (as 
defined in Section 2 of the Offer to Purchase), the signatures on the notice 
of withdrawal must be guaranteed by an Eligible Institution.  If Shares have 
been delivered pursuant to the procedures for book-entry transfer as set 
forth in Section 2 of the Offer to Purchase, any notice of withdrawal must 
also specify the name and number of the account at the appropriate Book-Entry 
Transfer Facility to be credited with the withdrawn Shares and otherwise 
comply with such Book-Entry Transfer Facility's procedures.  Withdrawals of 
tenders of Shares may not be rescinded, and any Shares properly withdrawn 
will thereafter 

                                     -3-


<PAGE>

be deemed not validly tendered for purposes of the Offer.  However, withdrawn 
Shares may be retendered by again following one of the procedures described 
in Section 2 of the Offer to Purchase at any time prior to the Expiration 
Date.

         The Offer to Purchase and the related Letter of Transmittal and 
other relevant materials will be mailed to record holders of Shares and 
furnished to brokers, dealers, banks, trust companies and similar persons 
whose names, or the names of whose nominees, appear on the shareholder lists 
or, if applicable, who are listed as participants in a clearing agency's 
security position listing, for subsequent transmittal to beneficial owners of 
Shares.

         The information required to be disclosed by Rule 14d-6(e)(1)(vii) 
under the Securities Exchange Act of 1934, as amended, is contained in the 
Offer to Purchase and is incorporated herein by reference.

include any portion of an includible payment for interest, dividends, or

underpayment attributable to that failure unless there is clear and convincing
evidence to the contrary.
(3) CIVIL PENALTY FOR FALSE INFORMATION WITH RESPECT TO WITHHOLDING.--If you
make a false statement with no reasonable basis which results in no imposition
of backup withholding, you are subject to a penalty of $500.

affirmations may subject you to criminal penalties including fines and/or
imprisonment.

Dear Jeff:

   This letter is in reference to the continuing discussions that we have 
had regarding a possible transaction (the "Transaction") between 
ElectroStar, Inc. ("ElectroStar") and Tyco International Ltd. ("Tyco").

   In consideration of Tyco's efforts in evaluating the proposed 
Transaction, ElectroStar hereby agrees that until the Termination Date (as 
hereinafter defined), it will not, and will cause its officers, directors, 
employees and other agents not to, directly or indirectly (x) take any action 
to solicit or initiate any Acquisition Proposal (as hereinafter defined), or 
(y) continue, initiate or engage in negotiations concerning any Acqusitition 
Proposal with, or disclose any non-public information relating to 
ElectroStar, or afford access to the properties, books or records of 
ElectroStar to, any corporation, partnership, person or other entity (except 
Tyco and its representatives) that may be considering or has heretofore made 
an Acquisition Proposal. The term "Acquisition Proposal" as used herein 
means any offer or proposal for, or indication of interest in, any 
acquisition of ElectroStar, whether by way of a merger, consolidation or other 
business combination involving any equity interest in, or a substantial 
portion of the assets of, ElectroStar, or the acquisition of more than 5% of 
the capital stock of ElectroStar (other than the proposed Transaction with 
Tyco). As used herein, the term "Termination Date" means 5:00 p.m. (E.S.T.) 
on Friday, November 22, 1996, which date and time shall automatically be 
extended until 5:00 p.m. (E.S.T.) on Wednesday, November 27, 1996 if (i) Tyco 
and ElectroStar have reached an agreement in principle with respect to the 
structure and form of definitive agreement for the proposed Transaction, and 
(ii) in ElectroStar's reasonable opinion, Tyco has diligently and in good 
faith pursued its investigation and evaluation of ElectroStar. In no event 
shall the Termination Date be extended beyond November 27, 1996.

   In consideration of ElectroStar's covenants in the preceding paragraph, 
Electrostar's provision to Tyco of access to certain ElectroStar "Evaluation 
Material" and other good and valuable consideration, the receipt and 
sufficiency of which is hereby acknowledged, Tyco hereby agrees that for a 
period of three years from the date hereof, neither Tyco nor any of its 
affiliates will (nor shall Tyco or its affiliates assist or encourage any 
other person to) directly or indirectly, unless specifically requested in 
writing in advance by ElectroStar's Board of Directors: (i) acquire or offer, 
seek, propose (either publicly or otherwise) or agree to acquire ownership 
(including, but not limited to, beneficial ownership as defined in

Rule 13d-3 under the Securities Exchange Act of 1934, as amended) of any of 
ElectroStar's securities or any rights or options to acquire such ownership, 
(ii) seek or propose to influence or control ElectroStar's management or 
policies, or (iii) make any public disclosure with respect to any of the 
foregoing; PROVIDED, HOWEVER, that the foregoing prohibitions shall 
automatically terminate and be of no further effect if (a) a tender offer or 
exchange offer commences for ElectroStar's securities, or (b) ElectroStar 
enters into a merger agreement pursuant to which ElectroStar's shareholders 
would own less than two-thirds of the surviving corporation's stock. Tyco 
further covenants that for a period of two (2) years following the date of 
this agreement, Tyco will not, directly or indirectly, solicit for employment 
or hire any employee of ElectroStar or any of ElectroStar's subsidiaries with 
whom such Tyco has had contact or who became known to Tyco in connection with 
its consideration of the Transaction.

   If you are in agreement with the foregoing, please sign and return one 
copy of this letter, whereupon this letter will constitue our agreement with 
respect to the subject matter hereof. This agreement may be executed in 
several counterparts, all of which together shall constitute one and the same 
agreement.

                                   Very truly yours,

                                   ELECTROSTAR, INC.

Mr. J. Brad McGee
Vice President
Tyco International Ltd.
One Tyco Park
Exeter, NH 03833-1108

Dear Brad:

     This letter is being provided to you in connection with your 
consideration of a possible transaction with or involving the business of 
ElectroStar, Inc. (together with its subsidiaries, the "COMPANY"). You have 
requested access to certain information, properties and personnel of the 
Company. As a condition to your being furnished such information, you agree 
to treat confidentially any information (herein collectively referred to as 
the "EVALUATION MATERIAL") concerning the Company, whether prepared by the 
Company, its advisers (including, without limitation, Trivest, Inc. and its 
affiliates (collectively, "TRIVEST") or otherwise, that is to be, or has 
been, furnished to you or your representatives (which term, when applied to 
the Company or yourselves shall include your or the Company's officers, 
directors, employees, partners, joint ventures, agents, legal counsel, 
accountants and financial or other advisers and, with respect to yourselves, 
shall include current or prospective financing sources) by or on behalf of 
the Company in accordance with the provisions of this agreement and to take 
or refrain from taking certain other actions herein set forth.

     The term "EVALUATION MATERIAL" includes (i) trade secrets concerning the 
business and affairs of the Company, product specifications, data, know-how, 
formulae, compositions, processes, designs, sketches, photographs, graphs, 
drawings, samples, inventions and ideas, past, current, and planned research 
and development, current and planned manufacturing or distribution methods 
and processes, customer lists, current and anticipated customer requirements, 
price lists, market studies, business plans, computer software and programs 
(including object code and source code), computer software and database 
technologies, systems, structures and architectures (and related processes, 
formulae, composition, improvements, devices, know-how, inventions, 
discoveries, concepts, ideas, designs, methods and information), and any 
other information, however documented, that is a trade secret within the 
meaning of applicable law, and (ii) information concerning the business 
and affairs of the Company (which includes historical financial statements, 
financial projections and budgets, historical and projected sales, capital 
spending budgets and plans, the names and backgrounds of key personnel, 
personnel training techniques and materials), however documented, that has 
been or may hereafter be provided or shown to you by the Company or its 
representatives or is otherwise obtained from review of Company documents or 
property or discussions with Company representatives by you or your 
representatives, irrespective of the form of the communication, and also 
includes all notes, analyses, compilations, studies, summaries, and other 
material prepared by you or your representatives contained or based, in whole 
or in part, on any information included in the foregoing, PROVIDED, HOWEVER, 
that the term "EVALUATION MATERIAL" does not include any information that (x) 
is already in your possession (other than information previously furnished to 
you by the Company or any of its representatives), or (y) is or becomes 
generally available to the public other than as a result of an unauthorized 
disclosure by you or your representatives, or (z) becomes available to you on 
a non-confidential basis from a source other than the Company or its 
representatives, PROVIDED that such source is not known by you to be bound by 
a confidentiality agreement or other obligation of secrecy to the Company or 
another person.

Mr. J. Brad McGee

     You agree that the Evaluation Material will be used by you and your 
representatives solely for the purpose of evaluating a possible transaction 
between you and the Company, and will be kept confidential by you and your 
representatives; PROVIDED, HOWEVER, that (i) any of such information may be 
disclosed to your representatives who need to know such information for the 
purpose of evaluating any such possible transaction (it being understood and 
agreed that such representatives shall be informed by you of the confidential 
nature of such information and shall be directed by you to treat such 
information confidentially), and (ii) any disclosure of such information may 
be made to which the Company or Trivest consents in writing.

     In the event that you or your Representatives receive a request or 
become legally compelled to disclose all or a part of the information 
contained in the Evaluation Material (by oral questions, interrogatories, 
requests for information or documents, subpoena civil investigative demand or 
similar process or otherwise), (i) you agree to promptly notify the Company 
of the existence, terms and circumstances surrounding such a request, so that 
it may seek an appropriate protective order and/or waive your compliance with 
the provisions of this agreement, and (ii) if disclosure of such information 
is required in the written opinion of your counsel, you agree to exercise 
reasonable efforts to obtain an order or other reliable assurance that 
confidential treatment will be accorded to such of the disclosed material 
which the Company so designates.

     Except as permitted by the previous paragraph, without the prior written 
consent of the Company, you will not, and will direct your representatives 
not to, disclose to any person (including, without limitation, any officers, 
employees or agents of the Company) either the fact that discussions or 
negotiations are taking place concerning a possible transaction between the 
Company and you or any of the terms, conditions or other facts with respect 
to any such possible transaction, including the status thereof.

     Without the prior written consent of the Company, you and your 
representatives will not, for a period of two years after the date of this 
letter agreement, solicit or cause to be solicited the employment of any 
person who is now employed by the Company and with whom you had contact in 
connection with the transactions that are the subject of this letter 
agreement.

     You agree that the Company shall be entitled to equitable relief, 
including an injunction and specific performance in the event of the breach 
of any of the provisions of this confidentiality agreement. Such remedies 
shall not be deemed to be the exclusive remedies for a breach of this 
confidentiality agreement by you or your Representatives, but shall be in 
addition to all other remedies available at law or in equity.

     Although you have been advised that the Company has endeavored to 
include in the Evaluation Material information known to it which it believes 
to be relevant for the purpose of your investigation, you acknowledge that 
neither the Company nor any of its representatives (including, without 
limitation, Trivest) have made or make any representation or warranty as to 
the accuracy or completeness of the Evaluation Material, and neither the 
Company nor its representatives (including, without limitation, Trivest) 
shall have any liability to you, your representatives or any affiliate of 
such persons resulting from the use of the Evaluation Material by you or such 
persons. Only those representations and warranties that are made to a party 
to a definitive agreement providing for a transaction as contemplated by this 
agreement when, as and if it is executed, and subject to such limitations and 
restrictions as may be specified in such agreement, shall have any legal 
effect.

Mr. J. Brad McGee

     At any time upon the request of the Company, you and your 
representatives will promptly redeliver to the Company all written Evaluation 
Material and any other written material containing or reflecting any 
information in the Evaluation Material (whether prepared by the Company, its 
representatives or otherwise) and will not retain any copies, extracts or 
other reproductions in whole or in part of such written material. Also, all 
documents, memoranda, notes and other writings whatsoever prepared by you or 
your representatives based on the information in the Evaluation Material will 
be destroyed, and such destruction shall, upon request of the Company, be 
certified in writing to the Company by an authorized officer supervising such 
destruction.

     It is further understood and agreed that no failure or delay by the 
Company in exercising any right, power or privilege hereunder shall operate 
as a waiver thereof, nor shall any single or partial exercise thereof 
preclude any other or further exercise thereof or the exercise of any right, 
power or privilege hereunder.

     You agree that unless and until a definitive agreement between the 
Company and you with respect to any transaction referred to in the first 
paragraph of this agreement has been executed and delivered, neither the 
Company, its affiliates nor you will be under any legal obligation of any 
kind whatsoever with respect to such a transaction, except for the matters 
specifically agreed to in this agreement. The agreements set forth in this 
agreement may be modified or waived only by a separate writing signed by the 
Company and by you expressly so modifying or waiving such agreements. It is 
further acknowledged and agreed that each of the parties hereto reserves the 
right to terminate discussions and negotiations at any time.

     This agreement shall be governed by and construed in accordance with the 
internal laws of the State of Florida.

     You obligations under this agreement shall terminate on the third 
anniversary of the date hereof.

     You acknowledge that you are aware, and that you will advise your 
representatives who are informed as to the matters which are the subject of 
this agreement, that the United States securities laws prohibit any person 
who has received from an issuer material, non-public information concerning 
the matters which are the subject of this agreement from purchasing or 
selling securities of such issuer or from communicating such information to 
any other person while such information is non-public under circumstances in 
which it is reasonably forseeable that such person is likely to purchase or 
sell such securities.

                            AGREEMENT AND PLAN OF MERGER
                            ----------------------------


    THIS AGREEMENT AND PLAN OF MERGER is made and entered into as of November 
27, 1996, among Tyco International, Ltd., a Massachusetts corporation 
("PARENT"), T3 Acquisition Corp., a Florida corporation and a wholly owned 
subsidiary of Parent ("SUB"), and ElectroStar, Inc., a Florida corporation 
(the "COMPANY").

    WHEREAS the respective Boards of Directors of Parent, Sub and the Company 
have approved the acquisition of the Company by Parent on the terms and 
subject to the conditions set forth in this Agreement; and

    WHEREAS, in furtherance of such acquisition, Parent proposes to cause Sub 
to make a tender offer (as it may be amended from time to time as permitted 
under this Agreement, the "OFFER") to purchase all the outstanding shares of 
Common Stock, par value $0.01 per share, of the Company (the "COMPANY COMMON 
STOCK"; the outstanding shares of Company Common Stock being hereinafter 
collectively referred to as the "SHARES") at a purchase price of $14.00 per 
share (the "OFFER PRICE"), net to the seller in cash, without interest 
thereon, upon the terms and subject to the conditions set forth in this 
Agreement; and the Board of Directors of the Company has adopted resolutions 
approving the Offer and the Merger (as defined below), recommending that the 
Company's shareholders accept the Offer and approving the acquisition of 
Shares by Sub pursuant to the Offer and the Shareholder Agreement (as defined 
below); and

    WHEREAS the respective Boards of Directors of Parent, Sub and the Company 
have each approved the merger of Sub into the Company (the "MERGER"), upon 
the terms and subject to the conditions set forth in this Agreement, whereby 
each share of Company Common Stock, other than shares of Company Common Stock 
owned directly or indirectly by Parent or the Company, will be converted into 
the right to receive the price per share paid in the Offer; and

    WHEREAS, concurrently with the execution of this Agreement and as an 
inducement to Parent to enter into this Agreement, Parent, Sub and certain 
shareholders of the Company are entering into a Shareholder Agreement (the 
"SHAREHOLDER AGREEMENT") pursuant to which (i) if necessary to validly tender 
shares in the Offer, the sole holder of the Company's outstanding shares of 
Class B non-voting common stock, par value $0.01 per share (the "CLASS B 
COMMON STOCK"), has agreed to convert such shares into shares of Company 
Common Stock, and (ii) each of such holder and certain other shareholders 
have, among other things, agreed to tender all of its Shares in the Offer, 
upon the terms and subject to the conditions set forth in the Shareholder 
Agreement; and

    WHEREAS Parent, Sub and the Company desire to make certain 
representations, warranties, covenants and agreements in connection with the 
Offer and the Merger and also to prescribe various conditions to the Offer 
and the Merger.

    NOW, THEREFORE, in consideration of the foregoing and the mutual 
covenants and agreements herein contained, and intending to be legally bound 
hereby, Parent, Sub and the Company hereby agree as follows:

                                      ARTICLE I

                                      THE OFFER

    SECTION 1.01.  THE OFFER.

    (a)  Subject to the provisions of this Agreement, as promptly as 
practicable but in no event later than five business days after the date of 
the public announcement by Parent and the Company of this Agreement, Sub 
shall, and Parent shall cause Sub to, commence the Offer.  The obligation of 
Sub to, and of Parent to cause Sub to, commence the Offer and accept for 
payment, and pay for, any Shares tendered pursuant to the Offer shall be 
subject only to those conditions set forth in Exhibit A (the "OFFER 
CONDITIONS") (any of which may be waived in whole or in part by Sub in its 
sole discretion, provided that, without the consent of the Company, Sub shall 
not waive the Minimum Condition (as defined in Exhibit A)) and to the terms 
and conditions of this Agreement. The initial scheduled expiration date of 
the Offer shall be 20 business days after the Offer is commenced. Sub 
expressly reserves the right to modify the terms of the Offer, except that, 
without the consent of the Company, Sub shall not (and Parent shall not cause 
Sub to) (i) reduce the number of Shares subject to the Offer, (ii) reduce the 
Offer Price, (iii) add to the Offer Conditions, (iv) except as provided in 
the next sentence, extend the expiration date of the Offer, (v) change the 
form of consideration payable in the Offer or (vi) amend any other term of 
the Offer in any manner adverse to the holders of the Shares. Notwithstanding 
the foregoing, Sub may, without the consent of the Company, (A) extend the 
Offer, if at the scheduled or extended expiration date of the Offer any of 
the Offer Conditions shall not be satisfied or waived, until such time as 
such conditions are satisfied or waived (PROVIDED, HOWEVER, that the 
expiration date may not be extended beyond January 31, 1997 without the 
consent of the Company), (B) extend the Offer for any period required by any 
rule, regulation, interpretation or position of the Securities and Exchange 
Commission (the "SEC") or the staff thereof applicable to the Offer, or (C) 
if all Offer Conditions are satisfied or waived but the number of shares of 
Common Stock tendered is less than 80% of the then outstanding number of 
shares of Company Common Stock (determined on a fully diluted basis for all 
outstanding stock options, Class B Common Stock and any other rights to 
acquire Shares), extend the Offer for an aggregate period of not more than 10 
business days (for all such extensions) beyond the latest expiration date 
that would be permitted under clause (A) or (B) of this sentence.  Subject to 
the terms and conditions of the Offer and this Agreement, Sub shall, and 
Parent shall cause Sub to, accept for payment, and pay for, all Shares 
validly tendered and not withdrawn pursuant to the Offer that Sub becomes 
obligated to accept for payment, and pay for, pursuant to the Offer as soon 
as practicable after the expiration of the Offer.

    (b)  On the date of commencement of the Offer, Parent and Sub shall file 
with the SEC a Tender Offer Statement on Schedule 14D-1 (the "SCHEDULE 
14D-1") with respect to the Offer, which shall contain an offer to purchase 
and a related letter of transmittal and summary advertisement (such Schedule 
14D-1 and the documents included therein pursuant to which the Offer will be 
made, together with any supplements or amendments thereto, the "OFFER 
DOCUMENTS"). Parent and Sub agree that the Offer Documents shall comply as to 
form in all material respects with the Securities Exchange Act of 1934, as 
amended (the "EXCHANGE ACT"), and the rules and regulations promulgated 
thereunder and the Offer Documents, on the date first published, sent or 
given to the Company's shareholders, shall not contain any untrue statement 
of a material fact or omit to state any material fact required to be stated 
therein or necessary in order to make the statements therein, in light of the 
circumstances under which they were made, not misleading, except that no 
representation or warranty is made by Parent or Sub with respect to 
information supplied by the Company or any of its shareholders specifically 
for inclusion or incorporation by reference in the Offer Documents.  Parent, 
Sub and the Company each agrees promptly to correct any information provided 
by it for use in the Offer Documents if and to the extent that such 
information shall have become false or misleading in any material respect, 
and Parent and Sub further agree to take all steps necessary to cause the 
Schedule 14D-1 as so corrected to be filed with the SEC and the other Offer 
Documents as so corrected to be disseminated to holders of Shares, in each 
case as and to the extent required by applicable Federal securities laws.  
The Company and its counsel shall be given reasonable opportunity to review 
and comment upon the Offer Documents prior to their filing with 

                                         2

<PAGE>

the SEC or dissemination to the shareholders of the Company.  Parent and Sub 
agree to provide the Company and its counsel in writing any comments Parent, 
Sub or their counsel may receive from the SEC or its staff with respect to 
the Offer Documents promptly after the receipt of such comments.

    (c)  Parent shall provide or cause to be provided to Sub on a timely 
basis the funds necessary to accept for payment, and pay for, any Shares that 
Sub becomes obligated to accept for payment, and pay for, pursuant to the 
Offer.

    SECTION 1.02.  COMPANY ACTIONS.

    (a)  The Company hereby approves of and consents to the Offer and 
represents that the Board of Directors of the Company, at a meeting duly 
called and held, duly and unanimously adopted resolutions (i) approving this 
Agreement, the Offer and the Merger (and such approval is sufficient to 
render inapplicable the provisions of Sections 607.0901 and 607.0902 of the 
Florida Business Corporations Act (the "CORPORATION LAW")), (ii) determining 
that the terms of the Offer and the Merger are fair, from a financial point 
of view, to, and in the best interests of, the Company's shareholders, and 
(iii) recommending that the Company's shareholders accept the Offer, tender 
their shares pursuant to the Offer and approve and adopt this Agreement.  The 
Company represents that its Board of Directors has received the opinion of 
Alex. Brown & Sons Incorporated that the proposed consideration to be 
received by the holders of Shares pursuant to the Offer and the Merger is 
fair, from a financial point of view, to such holders, and a complete and 
correct signed copy of such opinion has been delivered by the Company to 
Parent.

    (b)  On the date the Offer Documents are filed with the SEC, or promptly 
thereafter, the Company shall file with the SEC a Solicitation/Recommendation 
Statement on Schedule 14D-9 with respect to the Offer (such Schedule 14D-9, 
as amended from time to time, the "SCHEDULE 14D-9") containing the 
recommendation described in paragraph (a) and shall mail the Schedule 14D-9 
to the shareholders of the Company.  The Schedule 14D-9 shall comply as to 
form in all material respects with the requirements of the Exchange Act and 
the rules and regulations promulgated thereunder and, on the date filed with 
the SEC and on the date first published, sent or given to the Company's 
shareholders, shall not contain any untrue statement of a material fact or 
omit to state any material fact required to be stated therein or necessary in 
order to make the statements therein, in light of the circumstances under 
which they were made, not misleading, except that no representation or 
warranty is made by the Company with respect to information supplied by 
Parent or Sub specifically for inclusion in the Schedule 14D-9.  Each of the 
Company, Parent and Sub agrees promptly to correct any information provided 
by it for use in the Schedule 14D-9 if and to the extent that such 
information shall have become false or misleading in any material respect, 
and the Company further agrees to take all steps necessary to amend or 
supplement the Schedule 14D-9 and to cause the Schedule 14D-9 as so amended 
or supplemented to be filed with the SEC and disseminated to the Company's 
shareholders, in each case as and to the extent required by applicable 
Federal securities laws.  Parent and its counsel shall be given reasonable 
opportunity to review and comment upon the Schedule 14D-9 prior to its filing 
with the SEC or dissemination to shareholders of the Company.  The Company 
agrees to provide Parent and its counsel in writing any comments the Company 
or its counsel may receive from the SEC or its staff with respect to the 
Schedule 14D-9 promptly after the receipt of such comments.

    (c)  In connection with the Offer and the Merger, the Company shall cause 
its transfer agent to furnish Sub promptly with mailing labels containing the 
names and addresses of the record holders of Shares as of a recent date and 
of those persons becoming record holders subsequent to such date, together 
with copies of all lists of shareholders, security position listings and 
computer files and all other information in the Company's possession or 
control regarding the beneficial owners of Shares, and shall furnish to Sub 
such information and assistance (including updated lists of shareholders, 
security position listings and computer files) as Parent may reasonably 
request in communicating the Offer to the Company's shareholders. Subject to 
the requirements of applicable law, and except for such steps as are 
necessary to disseminate the Offer Documents and any other documents 
necessary to consummate the 

                                         3

<PAGE>



Merger, Parent and Sub and their agents shall hold in confidence the 
information contained in any such labels, listings and files, will use such 
information only in connection with the Offer and the Merger and, if this 
Agreement shall be terminated, will, upon request, deliver, and will use 
their best efforts to cause their agents to deliver, to the Company all 
copies of such information then in their possession or control.

                                     ARTICLE II

existence of Sub shall cease and the Company shall continue as the surviving

execute an appropriate amendment to this Agreement in order to reflect the 
foregoing.

    SECTION 2.02.  CLOSING.  The closing of the Merger will take place at 
10:00 a.m. (New York time) on a date to be specified by Parent or Sub, which

offices of Kramer, Levin, Naftalis & Frankel, counsel to Parent, unless 
another date, time or place is agreed to in writing by the parties hereto.

    SECTION 2.03.  EFFECTIVE TIME.  Subject to the provisions of this 
Agreement, as soon as practicable on or after the Closing Date, the parties 
shall file a certificate of merger or other appropriate documents (in any 
such case, the "CERTIFICATE OF MERGER") executed in accordance with the 
relevant provisions of the Corporation Law and shall make all other filings 
or recordings required under the Corporation Law.  The Merger shall become 
effective at such time as the Certificate of Merger is duly filed with the 
Florida Secretary of State, or at such other time as Sub and the Company 
shall agree should be specified in the Certificate of Merger (the time the 
Merger becomes effective being hereinafter referred to as the "EFFECTIVE 
TIME").

    SECTION 2.04.  EFFECTS OF THE MERGER.  The Merger shall have the effects 
set forth in the applicable provisions of the Corporation Law.

    SECTION 2.05.  ARTICLES OF INCORPORATION AND BY-LAWS.

thereof shall be amended and restated to provide in its entirety that the 
number of shares of capital stock that the Surviving Corporation shall be 
authorized to issue shall consist of 1,000 shares of common stock, (B) 
Article V thereof shall be amended and restated to provide in its entirety 
that the Surviving Corporation's Board shall consist of not less than three 
nor more than eleven members, with the exact number to be fixed from time to

<PAGE>

    SECTION 2.06.  DIRECTORS.  The directors of Sub immediately prior to the
Effective Time shall be the directors of the Surviving Corporation until the
earlier of their resignation or removal or until their respective successors
are duly elected and qualified, as the case may be.

    SECTION 2.07.  OFFICERS.  The officers of the Company immediately prior
to the Effective Time and such other persons as Parent shall designate shall

                                     ARTICLE III

                  EFFECT OF THE MERGER ON THE CAPITAL STOCK OF THE
                 CONSTITUENT CORPORATIONS; EXCHANGE OF CERTIFICATES

    SECTION 3.01.  EFFECT ON CAPITAL STOCK.  As of the Effective Time, by
virtue of the Merger and without any action on the part of the holder of any
Shares or any shares of capital stock of Sub:

    (a)  CAPITAL STOCK OF SUB.  Each issued and outstanding share of capital
stock of Sub shall be converted into and become one fully paid and
nonassessable shares of Common Stock, par value $.01 per share, of the
Surviving Corporation.

    (b)  CANCELLATION OF PARENT OWNED STOCK.  Each share of Company Common
Stock that is owned by Parent, Sub or any other subsidiary of Parent shall
automatically be canceled and retired and shall cease to exist, and no
consideration shall be delivered in exchange therefor.

    (c)  CANCELLATION OF COMPANY OWNED STOCK.  All Shares (as hereinafter
defined) that are held in the treasury of the Company or by any wholly owned
subsidiary of the Company and any Shares owned by Parent, Sub or any other
wholly owned subsidiary of Parent shall be cancelled and no consideration
shall be delivered in exchange therefor.

    (d)  CONVERSION OF COMPANY COMMON STOCK.  Subject to Section 3.01(e), 
each Share (and each share of Class B Common Stock, if any shall be 
outstanding, which, for purposes of this Article III, shall be included in 
the term "Shares") issued and outstanding (other than Shares to be canceled 
in accordance with Section 3.01(b)) shall be converted into the right to 
receive from the Surviving Corporation in cash, without interest, the price 
paid in the Offer (the "MERGER CONSIDERATION"). As of the Effective Time, all 
such Shares shall no longer be outstanding and shall automatically be 
canceled and retired and shall cease to exist, and each holder of a 
certificate representing any such Shares shall cease to have any rights with 
respect thereto, except the right to receive the Merger Consideration, 
without interest.

    (e)  SHARES OF DISSENTING SHAREHOLDERS.  Notwithstanding anything in this 
Agreement to the contrary, any issued and outstanding Shares held by a person 
(a "DISSENTING SHAREHOLDER") who objects to the Merger and complies with all 
the provisions of Florida law concerning the right of holders of Company 
Common Stock to dissent from the Merger and require appraisal of their Shares 
("DISSENTING SHARES") shall not be converted as described in Section 3.01(c) 
but shall become the right to receive such consideration as may be determined 
to be due to such Dissenting Shareholder pursuant to the laws of the State of 
Florida. If, after the Effective Time, such Dissenting Shareholder withdraws 
his demand for appraisal or fails to perfect or otherwise loses his right of 
appraisal, in any case pursuant to the Corporation Law, his Shares shall be 
deemed to be converted as of the Effective Time into the right to receive the 
Merger Consideration. The Company shall give Parent (i) prompt notice of any 
demands for appraisal of Shares received by the Company and (ii) the 
opportunity to participate in all negotiations and proceedings with respect 
to any such demands.

    SECTION 3.02.  EXCHANGE OF CERTIFICATES.

    (a)  PAYING AGENT.  Prior to the Effective Time, Parent shall designate a 
bank or trust company to act as paying agent in the Merger (the "PAYING 
AGENT"), and, from time to time on, prior to or after the Effective Time, 
Parent shall make available, or cause the Surviving Corporation to make 
available, to the Paying Agent funds in amounts and at the times necessary 
for the payment of the Merger Consideration upon surrender of certificates 
representing Shares as part of the Merger pursuant to Section 3.01 (it being 
understood that any and all interest earned on funds made available to the 
Paying Agent pursuant to this Agreement shall be turned over to Parent).

    (b)  EXCHANGE PROCEDURE.  As soon as reasonably practicable after the 
Effective Time, the Paying Agent shall mail to each holder of record of a 
certificate or certificates which immediately prior to the Effective Time 
represented Shares (the "CERTIFICATES"), (i) a letter of transmittal (which 
shall specify

                                         5



<PAGE>

that delivery shall be effected, and risk of loss and title to the 
Certificates shall pass, only upon delivery of the Certificates to the Paying 
Agent and shall be in a form and have such other provisions as Parent may 
reasonably specify) and (ii) instructions for use in effecting the surrender 
of the Certificates in exchange for the Merger Consideration.  Upon surrender 
of a Certificate for cancellation to the Paying Agent or to such other agent 
or agents as may be appointed by Parent, together with such letter of 
transmittal, duly executed, and such other documents as may reasonably be 
required by the Paying Agent, the holder of such Certificate shall be 
entitled to receive in exchange therefor the amount of cash into which the 
Shares theretofore represented by such Certificate shall have been converted 
pursuant to Section 3.01, and the Certificate so surrendered shall forthwith 
be canceled.  In the event of a transfer of ownership of Shares that is not 
registered in the transfer records of the Company, payment may be made to a 
person other than the person in whose name the Certificate so surrendered is 
registered, if such Certificate shall be properly endorsed or otherwise be in 
proper form for transfer and the person requesting such payment shall pay any 
transfer or other taxes required by reason of the  payment to a person other 
than the registered holder of such Certificate or establish to the 
satisfaction of the Surviving Corporation that such tax has been paid or is 
not applicable.  Until surrendered as contemplated by this Section 3.02, each 
Certificate (other than Certificates representing Dissenting Shares) shall be 
deemed at any time after the Effective Time to represent only the right to 
receive upon such surrender the amount of cash, without interest, into which 
the Shares theretofore represented by such Certificate shall have been 
converted pursuant to Section 3.01.  No interest will be paid or will accrue 
on the cash payable upon the surrender of any Certificate.  In the event any 
Certificate shall have been lost, stolen or destroyed, Parent may, in its 
discretion and as a condition precedent to the payment of the Merger 
Consideration in respect of the shares represented by such Certificate, 
require the owner of such lost, stolen or destroyed Certificate to deliver a 
bond in such sum as it may reasonably direct as indemnity against any claim 
that may be made against Parent, the Surviving Corporation or the Paying 
Agent.

    (c)  No FURTHER OWNERSHIP RIGHTS IN COMPANY COMMON STOCK.  All cash paid
upon the surrender of Certificates in accordance with the terms of this
Article III shall be deemed to have been paid in full satisfaction of all
rights pertaining to the Shares theretofore represented by such Certificates. 
At the Effective Time, the stock transfer books of the Company shall be
closed, and there shall be no further registration of transfers on the stock
transfer books of the Surviving Corporation of the Shares that were
outstanding immediately prior to the Effective Time.  If, after the Effective
Time, Certificates are presented to the Surviving Corporation or the Paying
Agent for any reason, they shall be canceled and exchanged as provided in this
Article III.

    (d)  NO LIABILITY.  At any time following the expiration of six months
after the Effective Time, the Surviving Corporation shall be entitled to
require the Paying Agent to deliver to it any funds (including any interest
received with respect thereto) which had been made available to the Paying
Agent and which have not been disbursed to holders of Certificates, and
thereafter such holders shall be entitled to look to the Surviving Corporation
(subject to any applicable abandoned property, escheat or similar law) only as
general creditors thereof with respect to the Merger Consideration payable
upon due surrender of their Certificates, without any interest thereon.
Notwithstanding the foregoing, none of Parent, Sub, the Company or the Paying
Agent shall be liable to any person in respect of any cash delivered to a
public official pursuant to any applicable abandoned property, escheat or
similar law.

                    REPRESENTATIONS AND WARRANTIES OF THE COMPANY

    The Company represents and warrants to Parent and Sub as follows:

    SECTION 4.01.  ORGANIZATION.  The Company and each of its subsidiaries is
a corporation duly organized, validly existing and in good standing under the
laws of the jurisdiction of its incorporation and has all requisite corporate
power and authority to carry on its business as now being conducted, except
where the failure to be so organized, existing and in good standing or to have
such power and authority could not be reasonably expected to (i) prevent or
materially delay the consummation of the Offer and/or the Merger or (ii) have
a material adverse effect (as defined in Section 10.03) on the Company. The
Company and each of its subsidiaries is duly qualified or licensed to do
business and in good standing in each jurisdiction in which the property
owned, leased or operated by it or the nature of the business conducted by it
makes such qualification or licensing necessary, except in such jurisdictions
where the failure to be so duly qualified or licensed and in good standing
could not reasonably be expected to have a material adverse effect on the
Company or prevent or materially delay the consummation of the Offer and/or
the Merger. The Company has made available to Parent complete and correct
copies of its Articles of Incorporation and By-laws and the certificates of
incorporation and by-laws (or similar organizational documents) of its
subsidiaries.

    SECTION 4.02.  SUBSIDIARIES.  The only subsidiaries of the Company are

subsidiary of the Company, free and clear of all pledges, claims, liens,
charges, encumbrances and security interests of any kind or nature whatsoever

Financial, Inc. upon the capital stock of the Subsidiaries pursuant to a
Credit Agreement dated as of January 31, 1996, and are duly authorized,
validly issued, fully paid and nonassessable.  Except for the capital stock of
its subsidiaries and the Company's ownership interest in certain incidental
investments (the aggregate book value of which do not exceed $5,000), the
Company does not own, directly or indirectly, any capital stock or other
ownership interest in any corporation, partnership, joint venture or other
entity.

    SECTION 4.03.  CAPITALIZATION. The authorized capital stock of the
Company consists of 21,782,934 shares of Company Common Stock, 782,934 shares
of Class B Common Stock and 1,000,000 shares of preferred stock, par value

reserved for issuance upon exercise of outstanding Company Stock Options (as
defined in Section 7.04), and (iv) no shares of Company Preferred Stock were
issued and outstanding. Except as set forth above, and except for shares
issued upon the exercise of Company Stock Options since November 20, 1996, as
of the date of this Agreement, no shares of capital stock or other voting
securities of the Company were issued, reserved for issuance or outstanding. 
All outstanding shares of capital stock of the Company are, and all shares
which may be issued will be, when issued, duly authorized, validly issued,
fully paid and nonassessable and not subject to preemptive rights.  There are
no bonds, debentures, notes or other indebtedness of the Company having the
right to vote (or convertible into, or exchangeable for, securities having the
right to vote) on any matters on which shareholders of the Company may vote.
Except as set forth above, as of the date of this Agreement, there are not any
securities, options, warrants, calls, rights, commitments, agreements,
arrangements or undertakings of any kind to which the Company or any of its
subsidiaries is a party or by which any of them is bound obligating the
Company or any of its subsidiaries to issue, deliver or sell, or cause to be
issued, delivered or sold, additional shares of capital stock or other voting

securities of the Company or of any of its subsidiaries or obligating the 
Company or any of its subsidiaries to issue, grant, extend or enter into any 
such security, option, warrant, call, right, commitment, agreement, 
arrangement or undertaking.  As of the date of this Agreement, there are not 
any outstanding contractual obligations (i) of the Company or any of its 
subsidiaries to repurchase, redeem or otherwise acquire any shares of capital 
stock of the Company or (ii) of the Company to vote or to dispose of any 
shares of the capital stock of any of its subsidiaries. Except as set forth 
in Section 4.03 of the disclosure schedule annexed hereto (the "DISCLOSURE 
SCHEDULE"), there are no restrictions on the right of the Company to vote or 
dispose of any shares of the capital stock of its subsidiaries.

    SECTION 4.04.  AUTHORITY.  The Company has the requisite corporate power
and authority to execute and deliver this Agreement and to consummate the
transactions contemplated hereby (other than, with respect to the Merger, the
approval and adoption of the terms of this Agreement by the holders of a
majority of the Shares (the "COMPANY SHAREHOLDER APPROVAL")).  The execution,
delivery and performance of this Agreement and the consummation by the Company
of the Merger and of the other transactions contemplated hereby have been duly
authorized by all necessary corporate action on the part of the Company and no
other corporate proceedings on the part of the Company are necessary to
authorize this Agreement or to consummate the transactions so contemplated (in
each case, other than, with respect to the Merger, the Company Shareholder
Approval). This Agreement has been duly executed and delivered by the Company
and, assuming this Agreement constitutes a valid and binding obligation of
Parent and Sub, constitutes a valid and binding obligation of the Company
enforceable against the Company in accordance with its terms, except as
limited by applicable bankruptcy, insolvency, reorganization, moratorium and
other laws of general application affecting enforcement of creditors' rights
generally.

    SECTION 4.05.  CONSENTS AND APPROVALS; NO VIOLATIONS.  Except for
filings, permits, authorizations, consents and approvals as may be required
under, and other applicable requirements of, the Exchange Act (including the
filing with the SEC of the Schedule 14D-9 and a proxy statement relating to

"PROXY STATEMENT")), the Hart-Scott-Rodino Antitrust Improvements Act of 1976,
as amended (the "HSR ACT"), and Sections 607.1103 - 607.1105 of the
Corporation Law, neither the execution, delivery or performance of this
Agreement by the Company nor the consummation by the Company of the
transactions contemplated hereby will (i) conflict with or result in any
breach of any provision of the Articles  of Incorporation or By-laws of the
Company or of the similar organizational documents of any of its subsidiaries,
(ii) require any filing with, or permit, authorization, consent or approval
of, any Federal, state or local government or any court, tribunal,

practice, neither the Company nor any of its subsidiaries has incurred any

    SECTION 4.10.  BENEFIT PLANS.

    (a)  Except as set forth in Section 4.10 of the Disclosure Schedule, each
"employee pension benefit plan" (as defined in Section 3(2) of the Employee
Retirement Income Security Act of 1974, as amended ("ERISA")) (a "PENSION
PLAN"), "employee welfare benefit plan" (as defined in Section 3(1) of ERISA)
(a "WELFARE PLAN") and each other plan, arrangement or policy (written or
oral) relating to stock options, stock purchases, compensation, deferred
compensation, bonuses, severance, fringe benefits or other employee benefits,
in each case maintained or contributed to, or required to be maintained or
contributed to, by the Company or its subsidiaries for the benefit of any
present or former employee, officer or director (each of the foregoing, a
"BENEFIT PLAN") has been administered in all material respects in accordance
with its terms.  The Company and its subsidiaries and all the Benefit Plans
are in compliance in all material respects with the applicable provisions of
ERISA, the Internal Revenue Code of 1986, as amended (the "CODE"), all other
applicable laws and all applicable collective bargaining agreements. Section
4.10 of the Disclosure Schedule sets forth a list of all material Benefit
Plans.  Except as set forth in Section 4.10(a) of the Disclosure Schedule,
none of the Welfare Plans promises or provides retiree medical or other
retiree welfare benefits to any person.  To the knowledge of the Company, no
fiduciary of a Benefit Plan has breached any of the responsibilities or
obligations imposed upon fiduciaries under Title I of ERISA, which breach
would reasonably be expected to result in any material liability to the
Company.  Each Benefit Plan intended to qualify under section 401(a) of the
Code and each trust intended to qualify under section 501(a) of the Code is
the subject of a favorable determination letter from the IRS, and nothing has
occurred which would reasonably be expected to impair such determination.  All
contributions required to be made with respect to any Benefit Plan pursuant to
the terms of the Benefit Plan or any collective bargaining agreement, have
been made on or before their due dates.  

    (b)  None of the Pension Plans is subject to Title IV of ERISA and none
of the Company or any other person or entity that, together with the Company,
is or was treated as a single employer under Section 414 of the Code or
pursuant to Title IV of ERISA (each, including the Company, a "COMMONLY
CONTROLLED ENTITY") has any liability under Title IV of ERISA (whether actual
or contingent) with respect to a Pension Plan, or to any other employee
pension benefit plan that is or was maintained, contributed to or required to
be contributed to by a Commonly Controlled Entity (other than for
contributions not yet due) or to the Pension Benefit Guaranty Corporation
(other than for payment of premiums not yet due), which liability has not been
fully paid.

    (c)  No Commonly Controlled Entity is required to contribute to any
"multiemployer plan" (as defined in Section 4001(a)(3) of ERISA) or has
withdrawn from any multiemployer plan where such withdrawal has resulted or
would result in any "withdrawal liability" (within the meaning of Section 4201
of ERISA) that has not been fully paid or as to which a commonly controlled
entity would have liability pursuant to Section 4212(c) of ERISA.

    (d)  Each Benefit Plan that is a Welfare Plan may be amended or
terminated at any time after the Effective Time without material liability to
the Company or its subsidiaries.

    SECTION 4.11.  OTHER COMPENSATION ARRANGEMENTS. Except as disclosed in
the Company SEC Documents or in Section 4.11 of the Disclosure Schedule, and

written (i) consulting agreement not terminable on not more than 60 calendar
days notice and involving the payment of more than $100,000 per annum, (ii)
agreement with any executive officer or other key employee of the Company or
any of its subsidiaries (x) the benefits of which are contingent, or the terms
of which are materially altered, upon the occurrence of a transaction
involving the Company of the nature contemplated by this Agreement or (y)
providing any term of employment or compensation guarantee extending for a
period longer than two years or the payment of more than $100,000 per year or
(iii) agreement or plan, including any stock option plan, stock appreciation
right plan, restricted stock


                                   11

<PAGE>

plan or stock purchase plan, any of the benefits of which will be increased, 
or the vesting of the benefits of which will be accelerated, by the 
occurrence of any of the transactions contemplated by this Agreement or the 
value of any of the benefits of which will be calculated on the basis of any 
of the transactions contemplated by this Agreement.

    SECTION 4.12.  LITIGATION.  Except as disclosed in the Company SEC
Documents or Section 4.12 of the Disclosure Schedule, there is no suit, claim,
action, proceeding or investigation pending before any Governmental Entity or,
to the best knowledge of the Company, threatened against the Company or any of
its subsidiaries that could reasonably be expected to have a material adverse
effect on the Company or prevent or materially delay the consummation of the
Offer and/or the Merger.  Except as disclosed in the Company SEC Documents or
Section 4.12 of the Disclosure Schedule, neither the Company nor any of its
subsidiaries is subject to any outstanding order, writ, injunction or decree
that could reasonably be expected to have a material adverse effect on the
Company or prevent or materially delay the consummation of the Offer and/or
the Merger.

    SECTION 4.13.  PERMITS; COMPLIANCE WITH LAW.  The Company and its
subsidiaries hold all permits, licenses, variances, exemptions, orders and
approvals of all Governmental Entities necessary for the lawful conduct of
their respective businesses (the "COMPANY PERMITS"), except for failures to
hold such permits, licenses, variances, exemptions, orders and approvals that
could not reasonably be expected to have a material adverse effect on the
Company.  The Company and its subsidiaries are in compliance with the terms of
the Company Permits, except where the failure so to comply could not
reasonably be expected to have a material adverse effect on the Company. 
Except as disclosed in the Company SEC Documents or in the Disclosure
Schedule,  the businesses of the Company and its subsidiaries are not being
conducted in violation of any law, ordinance or regulation of any Governmental
Entity, except for violations that could not reasonably be expected to have a
material adverse effect on the Company or prevent or materially delay the
consummation of the Offer and/or the Merger.  As of the date of this
Agreement, no investigation or review by any Governmental Entity with respect
to the Company or any of its subsidiaries is pending or, to the best knowledge
of the Company, threatened, nor has any Governmental Entity indicated an
intention to conduct any such investigation or review, other than, in each
case, those the outcome of which could not be reasonably expected to have a
material adverse effect on the Company or prevent or materially delay the
consummation of the Offer and/or the Merger.

    SECTION 4.14.  TAX MATTERS.

    (a)  The Company and each of its subsidiaries has filed all Federal
income tax returns and all other material tax returns and reports required to
be filed by it.  All such returns are complete and correct in all material
respects (except to the extent a reserve has been established on the most
recent financial statements contained in the Company SEC Documents (the "MOST
RECENT FINANCIAL STATEMENTS")).  Each of the Company and each of its
subsidiaries has paid (or the Company has paid on its subsidiaries' behalf)
all taxes required to be paid by it (without regard to whether a tax return is
required or to the amount shown on any tax return), except taxes for which an
adequate reserve has been established on the Most Recent Financial Statements.
The Most Recent Financial Statements reflect an adequate reserve for all taxes
payable by the Company and its subsidiaries for all taxable periods and
portions thereof through the date of such financial statements.

    (b)  Except as set forth in Section 4.14 of the Disclosure Schedule, no
material tax return of the Company or any of its subsidiaries is under audit
or examination by any taxing authority, and no written or unwritten notice of
such an audit or examination has been received by the Company or any of its
subsidiaries.  Each material deficiency resulting from any audit or
examination relating to taxes by any taxing authority has been paid, except
for deficiencies being contested in good faith.  No material issues relating
to taxes were raised in writing by the relevant taxing authority during any
presently pending audit or examination, and no material issues relating to
taxes were raised in writing by the relevant taxing authority in any completed
audit or examination that can reasonably be expected to recur in a later


                                    12

<PAGE>


taxable period.  The Federal income tax returns of the Company and each of 
its subsidiaries consolidated in such returns have not been examined by and 
settled with the Internal Revenue Service.

    (c)  There is no agreement or other document extending, or having the
effect of extending, the period of assessment or collection of any taxes and
no power of attorney with respect to any taxes has been executed or filed with
any taxing authority.

    (d)  No material liens for taxes exist with respect to any assets or
properties of the Company or any of its subsidiaries, except for liens for
taxes not yet due.

    (e)  None of the Company or any of its subsidiaries is liable for taxes
of any other person (other than taxes of the Company and its subsidiaries) or
is a party to or is bound by any tax sharing agreement, tax indemnity
obligation or similar agreement, arrangement or practice with respect to taxes
(including any advance pricing agreement, closing agreement or other agreement
relating to taxes with any taxing authority).

    (f)  None of the Company or any of its subsidiaries shall be required to
include in a taxable period ending after the Effective Time taxable income
attributable to income that accrued in a prior taxable period but was not
recognized in any prior taxable period as a result of the installment method
of accounting, the completed contract method of accounting, the long-term
contract method of accounting, the cash method of accounting or Section 481 of
the Code or comparable provisions of state, local or foreign tax law.

    (g)  As used in this Agreement, "TAXES" shall include all Federal, state,
local and foreign income, property, sales, excise, withholding and other
taxes, tariffs or governmental charges of any nature whatsoever, together with
all interest, penalties and additions imposed with respect to such amounts.

    (h)  Neither the Company nor, to the best knowledge of the Company, any
of its subsidiaries has filed a consent pursuant to or agreed to the
application of Section 341(f) of the Code.

    (i)  The Company is not a "United States real property holding company"
as defined in Section 897(c)(2) of the Code during the applicable period
specified in Section 897(c)(1)(A)(ii) of the Code.

    (j)  Neither the Company nor any of its subsidiaries is a party to any
joint venture, partnership, or other arrangement or contract which could be
treated as a partnership for federal income tax purposes.

any sale leaseback or any leveraged lease transaction that fails to satisfy
the requirements of Revenue Procedure 75-21 (or similar provisions of foreign
law).

    (l)  Neither the Company nor any of its subsidiaries is a party to any
agreement, contract, arrangement or plan that would result (taking into
account the transactions contemplated by this Agreement), separately or in the
aggregate, in the payment of any "excess parachute payments" within the
meaning of Section 280G of the Code.

    (m)  Except as set forth in Section 4.14 of the Disclosure Schedule,
neither the Company nor any of its subsidiaries has ever been a Subchapter S
corporation (as defined in Section 1361 (a)(1) of the Code).

    (n)  All material elections with respect to taxes affecting the Company
and its subsidiaries are disclosed or attached to the Company's tax returns.

<PAGE>


    (o)  There are no private letter rulings in respect of any tax pending
between the Company or its subsidiaries and any taxing authority.

    SECTION 4.15.  STATE TAKEOVER STATUTES.  The Board of Directors of the
Company has approved the Offer, the Merger, this Agreement and the acquisition
of Shares by Sub pursuant to the Offer and the Shareholder Agreement and such
approval is sufficient to render inapplicable to the Offer, the Merger, this
Agreement and the Shareholder Agreement and the transactions contemplated by
this Agreement and the Shareholder Agreement the provisions of Sections
607.0901 and 607.0902 of the Corporation Law.  To the best knowledge of the
Company, no other state takeover statute or similar statute or regulation
applies or purports to apply to the Offer, the Merger, this Agreement, the
Shareholder Agreement or any of the transactions contemplated by this
Agreement.

    SECTION 4.16.  BROKERS; FEES AND EXPENSES.  No broker, investment banker,
financial advisor or other person, other than Alex. Brown & Sons Incorporated

similar fee or commission in connection with the transactions contemplated by
this Agreement based upon arrangements made by or on behalf of the Company. 
The Company has furnished to Parent true and complete copies of all written
agreements or arrangements, and reduced to writing and furnished to Parent the

the Company and either of Alex. Brown & Sons Incorporated and Trivest II, Inc.


    SECTION 4.17.  INTELLECTUAL PROPERTY.

the circumstances giving rise to such inaccuracy) could not reasonably be
expected to have a material adverse effect on the Company:

         (1)  the Company and each of its subsidiaries owns, or is licensed
    or otherwise has the legally enforceable right to use (in each case,

    Property used in or necessary for the conduct of its business as
    currently conducted;

         (2)  no claims are pending or, to the best knowledge of the Company,
    threatened that the Company or any of its subsidiaries is infringing on
    or otherwise violating the rights of any person with regard to any
    Intellectual Property used by, owned by and/or licensed to the Company or
    its subsidiaries and, to the best knowledge of the Company, there are no
    valid grounds for any such claims;

         (3)  to the best knowledge of the Company, no person is infringing
    on or otherwise violating any right of the Company or any of its
    subsidiaries with respect to any Intellectual Property owned by and/or

         (4)  to the best knowledge of the Company, there are no valid
    grounds for any claim challenging the ownership or validity of any
    Intellectual Property owned by the Company or any of its subsidiaries or
    challenging the Company's or any of its subsidiaries' license or legally
    enforceable right to use any Intellectual Property licensed by it; and

         (5)  to the best knowledge of the Company, all patents, registered
    trademarks, service marks and copyrights held by the Company and each of
    its subsidiaries are valid and subsisting.

                                    14

<PAGE>

    (b)  For purposes of this Agreement, "INTELLECTUAL PROPERTY" means
trademarks (registered or unregistered), service marks, brand names,

registrations in any jurisdiction of, and applications in any jurisdiction to

any such registration or application; inventions, discoveries and ideas,

Company Stock is the only  vote of the holders of any class of capital stock
necessary to approve this Agreement and the Merger.

the Disclosure Schedule, the Company and each of its subsidiaries have good
and defensible title to all of their properties and assets, free and clear of
all liens, charges and encumbrances, except liens for taxes not yet due and
payable and such liens or other imperfections of title, if any, as do not
materially detract from the value of or interfere with the present use of the
property affected thereby or which could not reasonably be expected to have a

default or event of default (or event which with notice or lapse of time, or
both, would constitute a material default), except where the lack of such good
standing, validity and effectiveness or the existence of such default or event
of default could not reasonably be expected to have a material adverse effect.

duly organized, validly existing and in good standing under the laws of the
jurisdiction of its incorporation and has all requisite corporate power and
authority to carry on its business as now being conducted, except where the
failure to be so organized, existing and in good standing or to have such
power and authority could not be reasonably expected to prevent or materially
delay the consummation of the Offer and/or the Merger. Each of Parent and Sub
is duly qualified or licensed to do business and in good standing in each
jurisdiction in which the property owned, leased or operated by it or the
nature of the business conducted by it makes such qualification or licensing

contract, agreement or other instrument or obligation to which Parent or any
of its subsidiaries is a party or by which any of them or any of their
properties or assets may be bound or (iv) violate any order, writ, injunction,
decree, statute, rule or regulation applicable to Parent, any of its
subsidiaries or any of their properties or assets, except in the case of
clauses (iii) and (iv) for violations, breaches or defaults which could not,
individually or in the aggregate, be reasonably expected to prevent or
materially delay the consummation of the Offer and/or the Merger.

    SECTION 5.04.  INFORMATION SUPPLIED.  None of the information supplied or
to be supplied by Parent or Sub specifically for inclusion or incorporation by
reference in (i) the Offer Documents, (ii) the Schedule 14D-9, (iii) the

certificate or schedule furnished or to be furnished by Parent or Sub to the
Company in, or pursuant to the provisions of, this Agreement contains or shall

<PAGE>

    SECTION 6.02.  NO SOLICITATION.

    (a)  The Company and its officers, directors, employees, representatives 
and agents shall immediately cease any discussions or negotiations with any 
parties that may be ongoing with respect to an Acquisition Proposal (as 
hereinafter defined). From and after the date hereof until the termination of 
this Agreement, the Company shall not, nor shall it permit any of its 
subsidiaries to, authorize or permit any of its officers, directors or 
employees or any investment banker, financial advisor, attorney, accountant 
or other representative retained by it or any of its subsidiaries to, 
directly or indirectly, (i) solicit, initiate or knowingly encourage 
(including by way of furnishing non-public information or assistance), or 
knowingly take any other action to facilitate, any inquiries or the making of 
any proposal which constitutes, or may reasonably be expected to lead to, any 
Acquisition Proposal or (ii) participate in any discussions or negotiations 
regarding any Acquisition Proposal; PROVIDED, HOWEVER, that if, at any time 
the Board of Directors of the Company determines in good faith, after 
consultation with independent legal counsel (who may be the Company's 
regularly engaged independent counsel), that it is necessary to do so in 
order to comply with its fiduciary duties to the Company's shareholders under 
applicable law, the Company may, in response to an unsolicited Acquisition 
Proposal, and subject to compliance with Section 6.02(c), (x) furnish 
information with respect to the Company to any person pursuant to a 
confidentiality agreement in reasonably customary form, and (y) participate 
in discussions or negotiations regarding such Acquisition Proposal. For 
purposes of this Agreement, "ACQUISITION PROPOSAL" means any inquiry, 
proposal or offer from any person relating to any direct or indirect 
acquisition or purchase of 20% or more of the assets of the Company and its 
subsidiaries or 20% or more of any class of equity securities of the Company 
or any of its subsidiaries, any tender offer or exchange offer that if 
consummated would result in any person beneficially owning 20% or more of any 
class of equity securities of the Company or any of its subsidiaries, any 
merger, consolidation, business combination, sale of all or substantially all 
the assets, recapitalization, liquidation, dissolution or similar transaction 
involving the Company or any of its subsidiaries (other than the transactions 
between the parties hereto contemplated by this Agreement), or any other 
transaction the consummation of which could reasonably be expected to impede, 
interfere with, prevent or materially delay the Offer and/or the Merger or 
which could reasonably be expected to dilute materially the benefits to 
Parent of the transactions contemplated hereby.

    (b)  Except as set forth in this Section 6.02, neither the Board of
Directors of the Company nor any committee thereof shall (i) withdraw or
modify, or propose to withdraw or modify, in a manner adverse to Parent, the
approval or recommendation by such Board of Directors or such committee of the
Offer, this Agreement or the Merger, (ii) approve or recommend, or propose to
approve or recommend, any Acquisition Proposal or (iii) cause the Company to
enter into any agreement with respect to any Acquisition Proposal. 
Notwithstanding the foregoing, in the event that the Board of Directors of the
Company determines in good faith, after consultation with independent legal
counsel  (who may be the Company's regularly engaged independent counsel),
that it is necessary to do so in order to comply with its fiduciary duties to
the Company's shareholders under applicable law, the Board of Directors of the
Company may (subject to the other provisions of Section 6.02) withdraw or
modify its approval or recommendation of the Offer, this Agreement and the
Merger, approve or recommend a Superior Proposal (as defined below), cause the
Company to enter into an agreement with respect to a Superior Proposal or
terminate this Agreement, but in each case only at a time that is after the
fifth business day following Parent's receipt of written notice (a "NOTICE OF
SUPERIOR PROPOSAL") advising Parent that the Board of Directors of the Company
has received a Superior Proposal, specifying the material terms and conditions
of such Superior Proposal and identifying the person making such Superior
Proposal. In addition, if the Company proposes to enter into an agreement with
respect to any Acquisition Proposal, it shall concurrently with entering into
such agreement pay, or cause to be paid, to Parent the Termination Fee (as
such term is defined in Section 7.06(b)).  For purposes of this Agreement, a
"SUPERIOR PROPOSAL" means any bona fide proposal made by a third party to
acquire, directly or indirectly, for consideration consisting of cash and/or
securities, more than 20% of the shares of Company Common Stock then
outstanding or all or substantially all the assets of the Company and
otherwise on terms which the Board 

                                        22


<PAGE>

of Directors of the Company determines in its good faith judgment (based on 
the advice of a financial advisor of nationally recognized reputation) to be 
more favorable to the Company's shareholders than the Offer and the Merger.

    (c)  In addition to the obligations of the Company set forth in
paragraphs (a) and (b) of this Section 6.02, the Company shall promptly advise
Parent orally and in writing of any request for information or of any
Acquisition Proposal, the material terms and conditions of such request or
Acquisition Proposal and the identity of the person making such request or
Acquisition Proposal.

    (d)  Nothing contained in this Section 6.02 shall prohibit the Company
from taking and disclosing to its shareholders a position contemplated by Rule
14e-2(a) promulgated under the Exchange Act or from making any disclosure to
the Company's shareholders if, in the good faith judgment of the Board of
Directors of the Company, after consultation with independent legal counsel
(who may be the Company's regularly engaged independent counsel), failure so
to disclose would be inconsistent with its fiduciary duties to the Company's
shareholders under applicable law; PROVIDED, HOWEVER, neither the Company nor
its Board of Directors nor any committee thereof shall, except as permitted by
Section 6.02(b), withdraw or modify, or propose to withdraw or modify, its
position with respect to the Offer, this Agreement or the Merger or approve or
recommend, or propose to approve or recommend, an Acquisition Proposal.

    SECTION 6.03.  OTHER ACTIONS.  Except as contemplated by Section 6.02 or
the other provisions of this Agreement, the Company shall not, and shall not
permit any of its subsidiaries to, take any action that could reasonably be
expected to result in (i) any of the representations and warranties of the
Company set forth in this Agreement that are qualified as to materiality
becoming untrue, (ii) any of such representations and warranties that are not
so qualified becoming untrue in any material respect or (iii) any of the Offer
Conditions not being satisfied in all material respects.

duly call, give notice of, convene and hold a meeting of its shareholders (the
"SHAREHOLDERS MEETING") for the purpose of obtaining the Company Shareholder
Approval. The Company will, through its Board of Directors, recommend to its
shareholders that the Company Shareholder Approval be given.  Notwithstanding
the foregoing, if Sub or any other subsidiary of Parent shall acquire at least
80% of the outstanding Shares, the parties shall, at the request of Parent,
take all necessary and appropriate action to cause the Merger to become
effective as soon as practicable after the expiration of the Offer without a
Shareholders Meeting in accordance with Section 607.1104 of the Corporation
Law.

    (b)  If the Company Shareholder Approval is required by law, the Company 
will, at Parent's request, as soon as practicable following acceptance for 
payment of and payment for shares of Company Common Stock by Sub in the Offer, 
prepare and file a preliminary Proxy Statement (or, if applicable, an 
information statement in lieu of a proxy statement pursuant to Rule 14C under 
the Exchange Act, with all references herein to the Proxy Statement being 
deemed to refer to such information statement, to the extent applicable) with 
the SEC and will use its best efforts to respond to any comments of the SEC or
its staff and to cause the Proxy Statement to be mailed to the Company's share-
holders as promptly as practicable after responding to all such comments to 
the satisfaction of the staff. The Company will notify Parent promptly of the 
receipt of any comments from the SEC or its staff and of any request by the 

                                        23


<PAGE>

SEC or its staff for amendments or supplements to the Proxy Statement or
for additional information and will supply Parent with copies of all
correspondence between the Company or any of its representatives, on the one
hand, and the SEC or its staff, on the other hand, with respect to the Proxy
Statement or the Merger.  If at any time prior to the Shareholders Meeting
there shall occur any event that should be set forth in an amendment or
supplement to the Proxy Statement, the Company will promptly prepare and mail
to its shareholders such an amendment or supplement.  The Company will not
mail any Proxy Statement, or any amendment or supplement thereto, to which
Parent reasonably objects.

    (c)  Parent agrees to cause all Shares purchased pursuant to the Offer
and all other Shares owned by Parent or any subsidiary of Parent to be voted
in favor of the Company Shareholder Approval.

    SECTION 7.02.  ACCESS TO INFORMATION. Upon reasonable notice and subject
to restrictions contained in confidentiality agreements to which the Company
is subject (from which it shall use reasonable efforts to be released), the
Company shall, and shall cause each of its subsidiaries to, afford to Parent
and to the officers, employees, accountants, counsel and other representatives
of Parent access, during normal business hours to all their respective
properties, books, contracts, commitments and records and, during such period,
the Company shall (and shall cause each of its subsidiaries to) furnish
promptly to Parent (a) a copy of each report, schedule, registration statement
and other document filed or received by it during such period pursuant to SEC
requirements and (b) all other information concerning its business, properties
and personnel as Parent may reasonably request.  Except as otherwise agreed to
by the Company, unless and until Parent and Sub shall have purchased a
majority of the outstanding Shares pursuant to the Offer or otherwise, and
notwithstanding termination of this Agreement, the terms of the
confidentiality letter agreement, dated as of October 30, 1996, between the
Company and Parent shall apply to all information about the Company which has
been furnished under this Agreement by the Company to Parent or Sub.

    SECTION 7.03.  REASONABLE EFFORTS.  Each of the Company, Parent and Sub
agrees to use its reasonable efforts to take, or cause to be taken, all
actions necessary to comply promptly with all legal requirements which may be
imposed on itself with respect to the Offer and the Merger (which actions
shall include furnishing all information required under the HSR Act and in
connection with approvals of or filings with any other Governmental Entity)
and will promptly cooperate with and furnish information to each other in
connection with any such requirements imposed upon any of them or any of their
subsidiaries in connection with the Offer and the Merger.  Each of the
Company, Parent and Sub will, and will cause its subsidiaries to, use its
reasonable efforts to take all reasonable actions necessary to obtain (and
will cooperate with each other in obtaining) any consent, authorization, order
or approval of, or any exemption by, any Governmental Entity or other public
or private third party required to be obtained or made by Parent, Sub, the
Company or any of their subsidiaries in connection with the Offer and the
Merger or the taking of any action contemplated thereby or by this Agreement,
except that no party need waive any substantial rights or agree to any
substantial limitation on its operations or to dispose of or hold separate any
assets or otherwise take any action that would require a waiver of, or that is
inconsistent with the satisfaction of, the conditions of the Offer set forth
in clause (iii) or (iv) of subsection (a) of Exhibit A hereto.

    SECTION 7.04.  COMPANY STOCK OPTIONS; PLANS.

    (a)  Parent and the Company shall, effective as of the Effective Time, 
(i) cause each outstanding option to purchase Company Common Stock (a 
"COMPANY STOCK OPTION") issued pursuant to the Company's Second Amended and 
Restated Stock Option Plan (the "COMPANY STOCK OPTION PLAN"), whether or not 
exercisable or vested, to become fully exercisable and vested, (ii) cause 
each Company Stock Option that is outstanding to be canceled and (iii) in 
consideration of such cancellation and, except to the extent that Parent or 
Sub and the holder of any such Company Stock Option otherwise agree, cause 
the Company (or, at Parent's option, Sub) to pay such holders of Company 
Stock Options an amount in respect thereof equal to the product of (x) the 
excess, if any, of the Offer price over the exercise price of each such 
Company Stock Option and (y) the number of shares of Company Common Stock 
subject to the Company Stock Option immediately prior to its cancellation 
(such payment to be net of applicable withholding taxes).

    (b)  Except as may otherwise be agreed by Parent or Sub and the Company,
the Company Stock Option Plan shall terminate as of the Effective Time, and no
holder of Company Stock Options or any participant in the Company Stock Option
Plan shall have any rights thereunder to acquire any equity securities of the
Company, the Surviving Corporation or any subsidiary thereof.

    (c)  Except as may otherwise be agreed by Parent or Sub and the Company,
all other plans, programs or arrangements providing for the issuance or grant
of any other interest in respect of the capital stock of the Company or any of
its subsidiaries shall terminate as of the Effective Time, and no participant
in any such plans, programs or arrangements shall have any rights thereunder
to acquire any equity securities of the Company, the Surviving Corporation or
any subsidiary thereof.

    SECTION 7.05.  DIRECTORS.  Promptly upon the acceptance for payment of, 
and payment for, any Shares by Sub pursuant to the Offer which represent at 
least a majority of the outstanding Shares (on a fully diluted basis), Parent 
shall be entitled to designate such number of directors, rounded up to the 
next whole number, on the Board of Directors of the Company as will give 
Parent, subject to compliance with Section 14(f) of the Exchange Act, 
representation on the Board of Directors equal to the product of (a) the 
total number of directors on the Board of Directors and (b) the percentage 
that the number of shares of Company Common Stock purchased by Sub bears to 
the number of shares of Company Common Stock outstanding; PROVIDED, HOWEVER, 
that in the event that Sub's designees are elected to the Board of Directors 
of the Company, until the Effective Time such Board of Directors shall have 
at least two directors who are directors on the date of this Agreement and 
who are not officers of the Company (the "INDEPENDENT DIRECTORS"); and 
PROVIDED FURTHER that, in such event, if the number of Independent Directors 
shall be reduced below two for any reason whatsoever, the remaining 
Independent Director shall designate a person to fill such vacancy who shall 
be deemed to be an Independent Director for purposes of this Agreement or, if 
no Independent Directors then remain, the other directors shall designate two 
persons to fill such vacancies who shall not be officers or affiliates of the 
Company or any of its subsidiaries, or officers or affiliates of Parent or 
any of its subsidiaries, and such persons shall be deemed to be Independent 
Directors for purposes of this Agreement. Subject to applicable law, the 
Company shall take all action requested by Parent necessary to effect any 
such election, including mailing to its shareholders the Information 
Statement containing the information required by Section 14(f) of the 
Exchange Act and Rule 14f-1 promulgated thereunder, and the Company agrees to 
make such mailing with the mailing of the Schedule 14D-9 (provided that Sub 
shall have provided to the Company on a timely basis all information required 
to be included in the Information Statement with respect to Sub's designees). 
 In connection with the foregoing, the Company will promptly, at the option 
of Parent, either increase the size of the Company's Board of Directors 
and/or obtain the resignation of such number of its current directors as is 
necessary to enable Sub's designees to be elected or appointed to, and to 
constitute a majority of, the Company's Board of Directors as provided above.

    SECTION 7.06.  FEES AND EXPENSES.

    (a)  Except as provided below in this Section 7.06, all fees and expenses 
incurred in connection with the Offer, the Merger, this Agreement and the 
transactions contemplated by this Agreement shall be paid by the party 
incurring such fees or expenses, whether or not the Offer or the Merger is 
consummated.

    (b)  If (i)  Parent or Sub terminates this Agreement under Section 
9.01(c)(iii) or Section 9.01(d), (ii) either Parent or the Company terminates 
this Agreement under Section 9.01(b)(i), the Minimum Condition has failed to 
be satisfied and such failure is the result of any of the parties to the 
Shareholder Agreement having breached its obligation thereunder to tender its 
Shares in the Offer or (iii) the Company terminates this Agreement pursuant 
to Section 9.01(e), the Company shall assume and pay, or cause to be paid, a 
termination fee in the amount of $3,000,000 (the "Termination Fee").

    SECTION 7.07.  INDEMNIFICATION; INSURANCE.

    (a)  Parent and Sub agree that all rights to indemnification for acts or
omissions occurring prior to the Effective Time now existing in favor of the
current or former directors or officers (the "INDEMNIFIED PARTIES") of the
Company and its subsidiaries as provided in their respective certificates or
articles  of incorporation or by-laws (or similar organizational documents) or
existing indemnification contracts shall survive the Merger and shall continue
in full force and effect in accordance with their terms.

    (b)  In addition, Parent will provide, or cause the Surviving Corporation
to provide, for a period of not less than six years after the Effective Time,
the Company's current directors and officers an insurance and indemnification
policy that provides coverage for events occurring at or prior to the
Effective Time (the "D&O Insurance") that is no less favorable than the
Company's existing D&O Insurance policy or, if substantially equivalent
insurance coverage is unavailable, the best available coverage; provided,
however, that Parent and the Surviving Corporation shall not be required to
pay an annual premium for the D&O Insurance in excess of 200% of the annual
premium currently paid by the Company for such insurance, but in such case
shall purchase as much such coverage as possible for such amount.

    (c)  This Section 7.07 shall survive the consummation of the Merger at
the Effective Time, is intended to benefit the Company, Parent, the Surviving
Corporation and the Indemnified Parties and their respective heirs, personal
representatives, successors and assigns, and shall be binding on all
successors and assigns of Parent and the Surviving Corporation.

    SECTION 7.08   EMPLOYMENT AND BENEFIT ARRANGEMENTS.

    (a)  From and after the Effective Time, Parent shall cause the Surviving
Corporation to honor all employment, severance, termination and retirement
agreements to which the Company is a party, as such agreements are in effect
on the date hereof.

    (b)  For a one-year period following the Effective Time, Parent shall
cause the Surviving Corporation to provide those employees who are employees
of the Surviving Corporation at the Effective Time with benefits that are, in
the aggregate, no less favorable to such employees as are the benefits of the
Company available to such employees immediately prior to the Effective Time.

    (c)  The provisions of this Section 7.08 are not intended to create
rights of third party beneficiaries.

    SECTION 9.03.  AMENDMENT.  This Agreement may be amended by the parties
hereto, by action taken or authorized by their respective Boards of Directors,
at any time before or after obtaining the Company Shareholder Approval (if

waiver of those rights.

Agreement to an Article or a Section, such reference shall be to an Article or
a Section of this Agreement unless otherwise indicated.  The table of contents
and headings contained in this Agreement are for reference purposes only and

Whenever the words "INCLUDE", "INCLUDES" or "INCLUDING" are used in this
Agreement, they shall be deemed to be followed by the words "WITHOUT

Rule 12b-2 promulgated under the Exchange Act. As used in this Agreement,
"MATERIAL ADVERSE CHANGE" or  "MATERIAL ADVERSE EFFECT" means, when used in
connection with the Company, any change or effect (or any development that,
insofar as can reasonably be foreseen, is likely to result in any change or
effect) that, individually or in the aggregate with any such other changes or
effects, is materially adverse to the business, prospects, assets (including
intangible assets), financial condition or results of operations of the
Company and its subsidiaries taken as a whole.  Notwithstanding the foregoing,
a material adverse change or material adverse effect shall not include any
material adverse change or material adverse effect to the extent caused by any
change resulting from the announcement of the Offer or the Merger.

    SECTION 10.04. COUNTERPARTS.  This Agreement may be executed in two or
more counterparts, all of which shall be considered one and the same agreement
and shall become effective when two or 

                                        30


<PAGE>

more counterparts have been signed by each of the parties and delivered to 
the other parties, it being understood that all parties need not sign the 
same counterpart.

    SECTION 10.05. ENTIRE AGREEMENT; THIRD PARTY BENEFICIARIES.  This
Agreement (including the documents and the instruments referred to herein) (a)
constitute the entire agreement and supersede all prior agreements and
understandings, both written and oral, among the parties with respect to the

7.08, are not intended to confer upon any person other than the parties hereto
any rights or remedies hereunder.

extent provided herein, the Corporation Law, without regard to any applicable
conflicts of law.

long as this Agreement is in effect, neither the Company nor Parent shall, or

press release or other public announcement with respect to the transactions
contemplated by this Agreement without the consent of the other party, which
consent shall not be unreasonably withheld or delayed.

    SECTION 10.08. ASSIGNMENT.  Neither this Agreement nor any of the rights,
interests or obligations hereunder shall be assigned by any of the parties
hereto (whether by operation of law or otherwise) without the prior written
consent of the other parties, except that Sub may assign, in its sole
discretion, any or all of its rights, interests and obligations hereunder to
Parent or to any direct or indirect wholly owned subsidiary of Parent. Subject
to the preceding sentence, this Agreement will be binding upon, inure to the
benefit of and be enforceable by the parties and their respective successors
and assigns.

    SECTION 10.09. ENFORCEMENT.  The parties agree that irreparable damage
would occur in the event that any of the provisions of this Agreement were not
performed in accordance with their specific terms or were otherwise breached. 
It is accordingly agreed that the parties shall be entitled to an injunction
or injunctions to prevent breaches of this Agreement and to enforce
specifically the terms and provisions of this Agreement.  In addition, each of
the parties hereto (i) consents to submit such party to the personal
jurisdiction of any Federal court located in the State of New York in the
event any dispute arises out of this Agreement or any of the transactions
contemplated hereby, (ii) agrees that such party will not attempt to deny or
defeat such personal jurisdiction by motion or other request for leave from
any such court, and (iii) agrees that such party will not bring any action
relating to this Agreement or any of the transactions contemplated hereby in
any court other than a Federal court sitting in the State of New York.  The
prevailing party in any judicial action shall be entitled to receive from the
other party reimbursement for the  prevailing party's reasonable attorneys'
fees and disbursements, and court costs.

                            CONDITIONS OF THE OFFER


    Notwithstanding any other term of the Offer or this Agreement, Sub shall 
not be required to accept for payment or, subject to applicable rules and 
regulations of the SEC, including Rule 14e-1(c)  under the Exchange Act 
(relating to Sub's obligation to pay for or return tendered Shares after the 
termination or withdrawal of the Offer), to pay for any Shares tendered 
pursuant to the Offer unless (i) there shall have been validly tendered and 
not withdrawn prior to the expiration of the Offer such number of Shares that 
would constitute a majority of the outstanding Shares (determined on a fully 
diluted basis for all outstanding stock options, Class B Common Stock and any 
other rights to acquire Shares) (the "MINIMUM CONDITION") and (ii) any 
waiting period under the HSR Act applicable to the purchase of Shares 
pursuant to the Offer shall have expired or been terminated. Furthermore, 
notwithstanding any other term of the Offer or this Agreement, Sub shall not 
be required to accept for payment or, subject as aforesaid, to pay for any 
Shares not theretofore accepted for payment or paid for, and may terminate 
the Offer if, at any time on or after the date of this Agreement and before 
the acceptance of such Shares for payment or the payment therefor, any of the 
following conditions exists (other than as a result of any action or inaction 
of Parent or any of its subsidiaries that constitutes a breach of this 
Agreement):

    (a)  there shall have been instituted, pending or threatened any action
or proceeding by any court or other Government Entity which (i) seeks to
challenge the acquisition by Parent or Sub (or any of its affiliates) of
shares of Company Common Stock pursuant to the Offer, restrain or prohibit the
making or consummation of the Offer or the Merger, or obtain damages in
connection therewith in an amount which would reasonably be expected to have a
material adverse effect; (ii) seeks to make the purchase of or payment for
some or all of the shares of Common Stock pursuant to the Offer or the Merger
illegal; (iii) seeks to impose limitations on the ability of Parent (or any of
its affiliates) effectively to acquire or hold, or to require Parent or the
Company or any of their respective affiliates or subsidiaries to dispose of or
hold separate, any material portion of the assets or the business of Parent
and its affiliates or any material portion of the assets or the business of
the Company and its subsidiaries taken as a whole, as a result of the Offer or
the Merger; or (iv) seeks to impose material limitations on the ability of
Parent (or its affiliates) to exercise full rights of ownership of the shares
of Company Common Stock purchased by it, including, without limitation, the
right to vote the shares purchased by it on all matters properly presented to
the shareholders of the Company; 

    (b)  there shall have been promulgated, enacted, entered, enforced or
deemed applicable to the Offer or the Merger, by any statute, rule,
regulation, judgment, decree, order or injunction, other than the application
to the Offer or the Merger of applicable waiting periods under the HSR Act,
that is reasonably likely to directly or indirectly result in any of the
consequences referred to in clauses (i) through (iv) of subsection (a) above;

    (c)  (A) the representations and warranties of the Company in Section
4.03 of this Agreement shall not have been true and correct in all material
respects when made, or shall thereafter have ceased to be true and correct in
all material respects as if made as of such later date (other than
representations and warranties made as of a specified date) or (B) any of the
representations and warranties made by the Company in this Agreement shall not
have been true and correct in all material respects when made, or shall
thereafter have ceased to be true and correct in all material respects as if
made as of such later date (other than representations and warranties made as
of a specified date), except in any case where such failure to be true and
correct would not, in the aggregate, (x) have a material adverse effect, or
(y) prevent or materially delay the consummation of the Offer and/or the
Merger;

    (d)  the Company shall not in all material respects have performed in a
timely manner any material obligation and agreement and complied in all
material respects in a timely manner with any material covenant of the Company
to be performed or complied with by it under this Agreement;



<PAGE>

    (e)  (i) the Board of Directors of the Company shall have failed to
approve and recommend or shall have withdrawn or modified in a manner adverse
to Parent or Sub its approval or recommendation of the Offer, the Merger or
this Agreement, or approved or recommended any Acquisition Proposal, (ii) the
Company shall have entered into any agreement with respect to any Superior
Proposal in accordance with Section 6.02(b) of this Agreement or (iii) the
Board of Directors of the Company thereof shall have resolved to take any of
the foregoing actions; 

    (f)  any change, development, effect or circumstance shall have occurred
or be threatened (other than any affecting the electronics industry generally)
that would reasonably be expected to have a material adverse effect on the
Company;

    (g)  the Company shall commence a case under any chapter of Title XI of
the United States Code or any similar law or regulation; or a petition under
any chapter of Title XI of the United States Code or any similar law or
regulation is filed against the Company which is not dismissed within five
business days; or

    (h)  the Agreement shall have been terminated in accordance with its
terms;

which, in the reasonable judgment of Parent in any such case, and regardless
of the circumstances giving rise to any such condition, makes it inadvisable
to proceed with such acceptance for payment or payments.

    The foregoing conditions are for the sole benefit of Parent and Sub and
may, except as otherwise provided in this Agreement, be asserted by Parent or
Sub regardless of the circumstances giving rise to any such condition and may
be waived by Parent or Sub, in whole or in part, at any time and from time to
time, in the sole discretion of Parent.  The failure by Parent or Sub at any
time to exercise any of the foregoing rights shall not be deemed a waiver of
any right, the waiver of such right with respect to any particular facts or
circumstances shall not be deemed an ongoing right which may be asserted at
any time and from time to time.

    Should the Offer be terminated pursuant to the foregoing provisions, all
tendered Shares not theretofore accepted for payment shall forthwith be
returned by the Paying Agent to the tendering shareholders.

                                SHAREHOLDER AGREEMENT


    THIS SHAREHOLDER AGREEMENT is made and entered into as of this 27th day
of November 1996, among TYCO INTERNATIONAL, LTD., a Massachusetts corporation
("PARENT"), T3 ACQUISITION CORP., a Florida corporation and a wholly owned
subsidiary of Parent ("SUB"), and the other parties signatory hereto (each, a
"SHAREHOLDER").
                   
    WHEREAS each Shareholder desires that ELECTROSTAR, INC., a Florida
corporation (the "Company"), Parent and Sub enter into an Agreement and Plan
of Merger dated as of the date hereof (as the same may be amended or
supplemented, the "MERGER AGREEMENT") with respect to the merger of Sub with
and into the Company (the "MERGER"); and

    WHEREAS each Shareholder is executing this Agreement as an inducement to
Parent to enter into and execute, and to cause Sub to enter into and execute,
the Merger Agreement.

    NOW, THEREFORE, in consideration of the execution and delivery by Parent
and Sub of the Merger Agreement and the mutual covenants, conditions and
agreements contained herein and therein, the parties agree as follows:

    SECTION 1.     REPRESENTATIONS AND WARRANTIES.  Each Shareholder
severally, and not jointly, represents and warrants to Parent and Sub as
follows:

         (a)  Such Shareholder is the record and beneficial owner of the
number of shares of Common Stock, par value $.01 per share, of the Company
(the "COMPANY COMMON STOCK"), including shares of Company Common Stock
issuable upon conversion of shares of the Company's Class B non-voting common
stock, par value $.01 per share (the "Class B Common Stock"), separately
identified as such, set forth opposite such Shareholder's name in SCHEDULE A
hereto (as may be adjusted from time to time pursuant to Section 5, such
Shareholder's "SHARES").  Except for such Shareholder's Shares and any other
shares of Company Common Stock subject hereto, such Shareholder is not the
record or beneficial owner of any shares of Company Common Stock.

         (b)  This Agreement has been duly authorized, executed and
delivered by such Shareholder and constitutes the legal, valid and binding
obligation of such Shareholder, enforceable against such Shareholder in
accordance with its terms, except as limited by applicable bankruptcy,
insolvency, reorganization, moratorium and other laws of general application
affecting enforcement of creditors' rights generally.  Neither the execution
and delivery of this Agreement nor the consummation by such Shareholder of the
transactions contemplated hereby will result in a violation of, or a default
under, or conflict with, any contract, trust, commitment, agreement,
understanding, arrangement or restriction of any kind to which such
Shareholder is a party or bound or to which such Shareholder's Shares are
subject. To the best of such Shareholder's knowledge, consummation by such
Shareholder of the transactions contemplated hereby will not violate, or
require any consent, approval, or notice under, any provision of any 
judgment, order, decree, statute, law, rule or regulation applicable to such
Shareholder or such Shareholder's Shares, except for any necessary filing
under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended.

         (c)  Such Shareholder's Shares and the certificates representing
such Shares are now and at all times during the term hereof will be held by
such Shareholder, or by a nominee or custodian for the benefit of such
Shareholder, free and clear of all liens, claims, security interests, proxies,
voting trusts or agreements, understandings or arrangements or any other
encumbrances whatsoever, except for any such encumbrances or proxies arising
hereunder.


<PAGE>


         (d)  Except for fees payable to Alex. Brown & Sons Incorporated
and Trivest II, Inc., no broker, investment banker, financial adviser or other
person is entitled to any broker's, finder's, financial adviser's or other
similar fee or commission from Parent, Sub or the Company in  connection with
the transactions contemplated hereby based upon arrangements made by or on
behalf of such Shareholder (it being agreed that the representation set forth
in this Section 1(d) is being given by the holder of the Company's Class B
Common Stock only as to its knowledge).

         (e)  Such Shareholder understands and acknowledges that Parent
is entering into, and causing Sub to enter into, the Merger Agreement in
reliance upon such Shareholder's execution and delivery of this Agreement.
Such Shareholder acknowledges that the irrevocable proxy set forth in Section
4 is granted in consideration for the execution and delivery of the Merger
Agreement by Parent and Sub.

    SECTION 2.     AGREEMENT TO TENDER.  Each Shareholder hereby severally
agrees that it shall tender its Shares into the Offer (as defined in the
Merger Agreement) and that it shall not withdraw any Shares so tendered (it
being understood that the obligation contained in this sentence is
unconditional).  If necessary, the Shareholder holding the outstanding shares
of Class B Common Stock shall convert such shares into Company Common Stock
and tender the Company Common Stock issued upon conversion as provided in the
previous sentence.

     SECTION 3.    COVENANTS.  Each Shareholder severally, and not jointly,
agrees with, and covenants to, Parent and Sub as follows:

         (a)  Such Shareholder shall not, except as contemplated by the
terms of this Agreement, (i) TRANSFER (the term "transfer" shall include,
without limitation, for the purposes of this Agreement, any sale, gift, pledge
or other disposition), or consent to any transfer of, any or all of such
Shareholder's Shares or any interest therein, (ii) enter into any contract,
option or other agreement or understanding with respect to any transfer of any
or all of such Shares or any interest therein, (iii) grant any proxy,
power-of-attorney or other authorization or consent in or with respect to such
Shares, (iv) deposit such Shares into a voting trust or enter into a voting
agreement or arrangement with respect to such Shares or (v) take any other
action that would in any way restrict, limit or interfere with the performance
of its obligations hereunder or the transactions contemplated hereby;
provided, however, that nothing in this Agreement shall prohibit Kenton K.
Alder and F.G. Lindsey Burton from making charitable contributions of up to
54,000 and 20,000 shares of Company Common Stock, respectively.

         (b)  Subject to Section 8, such Shareholder shall not, nor shall it
permit any investment banker, attorney or other adviser or representative of
such Shareholder to, directly or indirectly, (i) solicit, initiate or
encourage the submission of, any Acquisition Proposal (as defined in the
Merger Agreement) or (ii) participate in any discussions or negotiations
regarding, or furnish to any person any information with respect to, or take
any other action to facilitate any inquiries or the making of any proposal
that constitutes, or may reasonably be expected to lead to, any Acquisition
Proposal.  Without limiting the foregoing, it is understood that any violation
of the restrictions set forth in the preceding sentence by an investment
banker, attorney or other adviser or representative of such Shareholder,
whether or not such person is purporting to act on  behalf of such Shareholder
or otherwise, shall be deemed to be a violation of this Section 3(b) by such
Shareholder.

                                       2

    SECTION 4.     GRANT OF IRREVOCABLE PROXY; APPOINTMENT OF PROXY.  

         (a)  Each Shareholder hereby irrevocably grants to, and
appoints, Parent and Jeff Mattfolk, J. Brad McGee, Brian Moroze and any other
individual who shall hereafter be designated by Parent, such Shareholder's
proxy and attorney-in-fact (with full power of substitution), for and in the
name, place and stead of such Shareholder, to vote such Shareholder's Shares,
or grant a consent or approval in respect of such Shares, at any meeting of
shareholders of the Company or at any adjournment thereof or in any other
circumstances upon which their vote, consent or other approval is sought,
against (i) any merger agreement or merger (other than the Merger Agreement
and the Merger), consolidation, combination, sale of substantial assets,
reorganization, joint venture, recapitalization, dissolution, liquidation or
winding up of or by the Company and (ii) any amendment of the Company's
Articles of Incorporation or By-laws or other proposal or transaction
(including any consent solicitation to remove or elect any directors of the
Company) involving the Company or any of its subsidiaries which amendment or
other proposal or transaction would in any manner impede, frustrate, prevent
or nullify, or result in a breach of any covenant, representation or warranty
or any other obligation or agreement of the Company under or with respect to,
the Offer, the Merger, the Merger Agreement or any of the other transactions
contemplated by the Merger Agreement (each of the foregoing in clause (i) or
(ii) above, a "COMPETING TRANSACTION").

         (b)  Such Shareholder represents that any proxies heretofore
given in respect of such Shareholder's Shares are not irrevocable, and that
any such proxies are hereby revoked.

         (c)  Such Shareholder hereby affirms that the irrevocable proxy
set forth in this Section 4 is given in connection with the execution of the
Merger Agreement, and that such irrevocable proxy is given to secure the
performance of the duties of the Shareholder under this Agreement.  Such
Shareholder hereby further affirms that the irrevocable proxy is coupled with
an interest and may under no circumstances be revoked.  Such Shareholder
hereby ratifies and confirms all that such irrevocable proxy may lawfully do
or cause to be done by virtue hereof.  Such irrevocable proxy is executed and
intended to be irrevocable in accordance with the provisions of Section
607.0722 of the Florida Business Corporations Act (the "CORPORATION LAW").

    SECTION 5.     CERTAIN EVENTS.  Each Shareholder agrees that this
Agreement and the obligations hereunder shall attach to such Shareholder's
Shares and shall be binding upon any person or entity to which legal or
beneficial ownership of such Shares shall pass, whether by operation of law or
otherwise, including without limitation such Shareholder's heirs, guardians,
administrators or successors.  In the event of any stock split, stock
dividend, merger, reorganization, recapitalization or other change in the
capital structure of the Company affecting the Company Common Stock, or the
acquisition of additional shares of Company Common Stock or other securities
or rights of the Company by any Shareholder, the number of Shares listed on
Schedule A beside the name of such Shareholder shall be adjusted appropriately
and this Agreement and the obligations hereunder shall attach to any
additional shares of Company Common Stock or other securities or rights of the
Company issued to or acquired by such Shareholder.

    SECTION 6.     STOP TRANSFER; LEGEND.  The Company agrees with, and
covenants to, Parent that the Company shall not register the transfer of any
certificate representing any Shareholder's Shares, unless such transfer is
made to Parent or Sub or otherwise in compliance with this Agreement.  Each
Shareholder agrees that such Shareholder will tender to the Company, within
five business days after the date hereof, any and all certificates
representing such Shareholder's Shares and the Company will inscribe upon such
certificates the following legend:  "The shares of Common Stock, par value
$.01 per share, of the Company represented by this certificate are subject to
a Shareholder Agreement dated as

                                       3

<PAGE>


of November 27, 1996, and may not be sold or otherwise transferred, except in 
accordance therewith. Copies of such Agreement may be obtained at the 
principal executive offices of the Company.

    SECTION 7.     VOIDABILITY.  If prior to the execution hereof, the Board
of Directors of the Company shall not have duly and validly authorized and
approved by all necessary corporate action the acquisition of Company Common
Stock by Parent and Sub and the other transactions contemplated by this
Agreement and the Merger Agreement, so that by the execution and delivery
hereof Parent or Sub would become, or could reasonably be expected to become,
an "Interested shareholder" with whom the Company would be prevented for any
period pursuant to Section 607.0901 of the Corporation Law from engaging in
any "Affiliated transaction" (as such terms are defined in Section 607.0901 of
the Corporation Law) then this Agreement shall be void and unenforceable until
such time as such authorization and approval shall have been duly and validly
obtained.

    SECTION 8.     SHAREHOLDER CAPACITY.  No person executing this Agreement
who is or becomes during the term hereof a director or officer of the Company
makes any agreement or understanding herein in his or her capacity as such
director or officer.  Each Shareholder signs solely in its capacity as the
record holder and beneficial owner of such Shareholder's Shares and nothing
herein shall limit or affect any actions taken by a Shareholder or any
officer, director, partner or affiliate of such Shareholder in its capacity as
an officer or director of the Company to the extent specifically permitted by
the Merger Agreement.

    SECTION 9.     FURTHER ASSURANCES.  Each Shareholder shall, upon request
of Parent or Sub execute and deliver any additional documents and take such
further actions as may reasonably be deemed by Parent or Sub to be necessary
or desirable to carry out the provisions hereof and to vest the power to vote
such Shareholder's Shares as contemplated by Section 4 in Parent and the other
irrevocable proxies described therein.

    SECTION 10.    TERMINATION.  This Agreement, and all rights and
obligations of the parties hereunder, shall terminate upon the earlier of (a)
the date upon which the Merger Agreement is terminated in accordance with its
terms either (i) by Parent or Sub (provided that no termination under this
clause shall relieve any Shareholder of liability for such shareholder's
breach of its or his obligations under this Agreement) or (ii) by mutual
written consent of Parent, Sub and the Company or (b) the date that Parent or
Sub shall have purchased and paid for the Shares of each Shareholder pursuant
to Section 2.

    SECTION 11.    PUBLIC ANNOUNCEMENTS.  Each Shareholder will consult with
Parent before issuing, and provide Parent with the opportunity to review and
comment upon, any press release or other public statements with respect to the
transactions contemplated by this Agreement and the Merger Agreement, and
shall not issue any such press release or make any such public statement prior
to such consultation, except as may be required by applicable law, court
process or by obligations pursuant to any listing agreement with any national
securities exchange.

    SECTION 12.    MISCELLANEOUS. 

         (a)  Capitalized terms used and not otherwise defined in this
Agreement shall have the respective meanings assigned to such terms in the
Merger Agreement.

         (b)  All notices, requests, claims, demands and other
communications under this Agreement shall be in writing and shall be deemed
given if delivered personally or sent by overnight courier (providing proof of
delivery) to the parties at the following addresses (or at such other address
for a party as shall be specified by like notice): (i) if to Parent or Sub, to
the address set forth in Section 

                                       4

<PAGE>


10.02 of the Merger Agreement; and (ii) if to a Shareholder, to the address 
set forth on Schedule A hereto, or such other address as may be specified in 
writing by such Shareholder.

         (c)  The headings contained in this Agreement are for reference
purposes only and shall not affect in any way the meaning or interpretation of
this Agreement.

         (d)  This Agreement may be executed in two or more counterparts, all
of which shall be considered one and the same agreement, and shall become
effective (even without the signature of any other Shareholder) as to any
Shareholder when one or more counterparts have been signed by each of Parent,
Sub and such Shareholder and delivered to Parent, Sub and such Shareholder.

         (e)  This Agreement (including the documents and instruments
referred to herein) constitutes the entire agreement, and supersedes all prior
agreements and understandings, both written and oral, among the parties with
respect to the subject matter hereof.

         (f)  This Agreement shall be governed by, and construed in
accordance with, the laws of the New York and, to the extent expressly
provided herein, the Corporation Law, regardless of the laws that might
otherwise govern under applicable principles of conflicts of laws thereof.

         (g)  Neither this Agreement nor any of the rights, interests or
obligations under this Agreement shall be assigned, in whole or in part, by
operation of law or otherwise, by any of the parties without the prior written
consent of the other parties, except by laws of descent. Any assignment in
violation of the foregoing shall be void.

         (h)  If any term, provision, covenant or restriction herein, or the
application thereof to any circumstance, shall, to any event, be held by a
court of competent jurisdiction to be invalid, void or unenforceable, the
remainder of the terms, provisions, covenants and restrictions herein and the
application thereof to any other circumstances, shall remain in full force and
effect, shall not in any way be affected, impaired or invalidated, and shall
be enforced to the fullest extent permitted by law.

         (i)  Each Shareholder agrees that irreparable damage would occur and
that Parent and Sub would not have any adequate remedy at law in the event
that any of the provisions of this Agreement were not performed in accordance
with their specific terms or were otherwise breached.  It is accordingly
agreed that Parent and Sub shall be entitled to an injunction or injunctions
to prevent breaches by any Shareholder of this Agreement and to enforce
specifically the terms and provisions of this Agreement.  Each of the parties
hereto (i) consents to submit such party to the personal jurisdiction of any
Federal court located in the State of New York in the event any dispute arises
out of this Agreement or any of the transactions contemplated hereby, (ii)
agrees that such party will not attempt to deny or defeat such personal
jurisdiction by motion or other request for leave from any such court, (iii)
agrees that such party will not bring any action relating to this Agreement or
any of the transactions contemplated hereby in any court other than a Federal
court located in the State of New York.  The prevailing party in any judicial
action shall be entitled to receive from the other party reimbursement for the
prevailing party's reasonable attorneys' fees and disbursements, and court
costs.

         (j)  No amendment, modification or waiver in respect of this
Agreement shall be effective against any party unless it shall be in writing
and signed by such party.
