                                                                   July 12, 1999

Dear Raychem Stockholder:

    You are cordially invited to attend a Special Meeting of Stockholders of
Raychem Corporation, which will be held on August 12, 1999 at 300 Constitution
Drive, Menlo Park, California 94025 at 10:00 a.m. Pacific Time.

    At the meeting, you will be asked to approve and adopt the Agreement and
Plan of Merger and Reorganization, dated as of May 19, 1999, among Raychem, Tyco
International Ltd. and Tyco International (PA) Inc., a wholly owned subsidiary
of Tyco. The merger agreement provides for, among other things, the merger of
Raychem with Tyco (PA).

    If this merger is approved, all of the outstanding shares of Raychem common
stock will be exchanged for the aggregate consideration of approximately $1.44
billion in cash and 16.1 million Tyco shares, based on the number of outstanding
shares of Raychem common stock as of July 7, 1999. The cash and Tyco shares will
be apportioned so that you will receive for each of your shares of Raychem
common stock merger consideration having a value of $18.50 plus the value of
0.2070 of a Tyco share. You will be able to elect to receive your pro rata share
of the merger consideration in either cash, Tyco shares or a combination of cash
and shares. If more stockholders elect cash than can be paid with the available
aggregate cash consideration, cash electing stockholders will receive a
combination of cash and shares according to a proration formula. Similarly, if
more stockholders elect Tyco shares than can be paid with the available
aggregate Tyco share consideration, share electing stockholders will receive a
combination of shares and cash according to a proration formula. The
accompanying Proxy Statement/ Prospectus provides a detailed description of the
proposed merger, the merger consideration and the proration mechanisms, as well
as the effects of the merger on you as a stockholder and on Raychem. I urge you
to read the enclosed materials carefully.

    AFTER CAREFUL CONSIDERATION, YOUR BOARD OF DIRECTORS HAS UNANIMOUSLY
DETERMINED THAT THE MERGER IS FAIR TO AND IN THE BEST INTERESTS OF RAYCHEM AND
ITS STOCKHOLDERS AND UNANIMOUSLY RECOMMENDS THAT YOU VOTE FOR THE APPROVAL AND
ADOPTION OF THE MERGER AGREEMENT.

    YOUR VOTE IS VERY IMPORTANT.  Whether or not you plan to attend the meeting,
please take the time to vote on the proposal submitted to you by completing and
mailing the enclosed proxy card to us.

                                    Sincerely,

                                    /s/ Richard A. Kashnow

                                    Richard A. Kashnow
                                    CHAIRMAN OF THE BOARD, PRESIDENT AND CHIEF
                                    EXECUTIVE OFFICER
    SEE "RISK FACTORS" BEGINNING ON PAGE 7 FOR A DISCUSSION OF ISSUES WHICH
SHOULD BE CONSIDERED BY STOCKHOLDERS WITH RESPECT TO THE MERGER.
    Neither the Securities and Exchange Commission nor any state securities
commission has approved or disapproved the Tyco common shares to be issued in
the merger or determined if this Proxy Statement/Prospectus is truthful or
complete. Any representation to the contrary is a criminal offense.

Proxy Statement/Prospectus dated July 12, 1999 and first mailed to stockholders
on or about July 14, 1999.

              QUESTIONS AND ANSWERS ABOUT THE TYCO/RAYCHEM MERGER

    Q.  WHY ARE TYCO AND RAYCHEM PROPOSING TO MERGE?

    A.  Tyco and Raychem are engaged in a number of complementary businesses,
and the merger will create opportunities for cost savings and synergies. By
synergies we mean that the companies will be able to sell to one another's
customers, offer customers a more comprehensive product line, use a combined
worldwide distribution network and jointly pursue future acquisitions. The goal
is to create increased value for stockholders through higher earnings per share.

    Based on current market prices for Tyco shares, all Raychem stockholders
will receive a significant premium for their shares over the value of the
Raychem common stock on May 18, 1999, the day before the merger was publicly
announced. Raychem stockholders who receive Tyco shares in the merger will have
an interest in a larger and more diversified manufacturing and service company.

    Q.  WHAT WILL I RECEIVE IN THE MERGER?

    A.  You will receive cash, a fraction of a Tyco common share or a
combination of cash and a fraction of a Tyco common share, in each case having a
value of $18.50 plus the value of 0.2070 of a Tyco common share, for each of
your shares of Raychem common stock. The cash and/ or Tyco shares payable to you
in the merger will be allocated in accordance with the election and proration
procedures described later in this document.

    Q.  WHAT SHOULD I DO NOW?

    A.  VOTING. You should cast your vote on the merger by completing, signing
and dating your proxy card. The completed proxy card should be returned in the
enclosed self-addresed postage paid envelope. You can also attend the special
meeting and vote in person.

    THE BOARD OF DIRECTORS OF RAYCHEM RECOMMENDS THAT YOU VOTE FOR THE APPROVAL
AND ADOPTION OF THE MERGER AGREEMENT.

    ELECTION FORMS.  If you have a preference for receiving cash, Tyco shares or
a particular combination of cash and shares for your shares of Raychem common
stock, complete the enclosed election form indicating your preference. The
certificates representing your shares of Raychem stock must accompany the
election form. Your completed election form and your stock certificates should
be returned in the enclosed self-addressed postage paid envelope.

    Q.  WHEN SHOULD I SEND IN MY PROXY CARD? CAN I CHANGE MY VOTE?

    A.  You should send in your proxy card as soon as possible so that your
shares will be voted at the meeting. You can change your vote at any time prior
to the special meeting by submitting a later dated signed proxy card or by
attending the special meeting and voting in person.

    Q.  BY WHEN MUST I SEND IN MY ELECTION FORM? CAN I CHANGE OR REVOKE MY
ELECTION?

    A.  Your election form must be returned no later than the election deadline,
which is the close of business on the last business day before the date on which
the merger takes effect. The merger is expected to take effect on the date
Raychem stockholders approve and adopt the merger agreement. Therefore,
regardless of how you vote, if you wish to make an election, you should make
sure that the exchange agent receives your election form no later than 5:00 p.m.
Eastern Time on August 11, 1999. You may change your election by delivering a
later dated election form to the exchange agent before the election deadline.
You may revoke your election by written notice of revocation to the exchange
agent before the election deadline.

    Q.  IF MY SHARES OF RAYCHEM COMMON STOCK ARE HELD BY A BANK OR BROKER, HOW
CAN I VOTE AND MAKE AN ELECTION?

    A.  If your shares are held by a bank, broker or other fiduciary, you must
instruct the fiduciary to vote and make the election on your behalf.

    Q.  AM I REQUIRED TO COMPLETE AN ELECTION FORM IN ORDER TO RECEIVE MY MERGER
CONSIDERATION?

    A.  No. If you do not make an election, you will still receive the merger
consideration. However, if you have a preference for a specific form or mix of
merger consideration and do not make an election, we will not take your
preference into consideration. You will receive merger consideration in whatever
form or mix remains after giving effect to the preferences of the Raychem
stockholders that do make elections.

    Q.  WHAT SHOULD I DO IF I HAVE QUESTIONS?

    A.  You should call Georgeson & Company Inc. at 800-223-2064 (toll free in
the United States) or 212-440-9800 (call collect).

                       RAYCHEM SPECIAL MEETING (PAGE 16)
    The special meeting of the Raychem stockholders will be held on August 12,
1999 at 300 Constitution Drive, Menlo Park, California 94025 at 10:00 a.m.
Pacific Time.
    The record date for Raychem stockholders entitled to receive notice of and
to vote at the Raychem special meeting is the close of business on July 7, 1999.
On that date, there were 77,800,919 shares of Raychem common stock outstanding.
                         MERGER CONSIDERATION (PAGE 43)
    Each share of Raychem common stock will be exchanged in the merger for
merger consideration having a value of $18.50 plus the value, at the time of the
merger, of 0.2070 Tyco common shares. This value is referred to as the "per
share value of the merger consideration." Raychem stockholders may elect to
receive their merger consideration in the form of cash, Tyco common shares or a
combination of cash and Tyco common shares. However, the total amount of cash
that Tyco will pay in the merger is fixed at $18.50 multiplied by the number of
shares of Raychem common stock outstanding at the time of the merger. If any
Raychem stockholders exercise appraisal rights, the total amount of cash paid in
the merger will be reduced by the product of the number of shares of Raychem
common stock for which appraisal is sought multiplied by the per share value of
the merger consideration. Also, the total number of Tyco common shares that Tyco
will deliver to Raychem stockholders in the merger is fixed at 0.2070 multiplied
by the number of shares of Raychem stock outstanding at the time of the merger.
Therefore, if more cash consideration is elected than the amount of cash
available for payment, there will be proration, and the Raychem common stock
with respect to which cash is elected will be exchanged for a combination of
cash and Tyco shares. Similarly, if more stock consideration is elected than the
number of Tyco shares available for payment, there will be proration, and the
Raychem common stock with respect to which Tyco shares is elected will be
exchanged for a combination of Tyco common shares and cash. For a description of
the proration rules, see "Merger Consideration--The Proration Rules" beginning
on page 45. Shares of restricted Raychem common stock that do not vest on or
before the occurrence of the merger will each be exchanged for 0.4140 of a Tyco
common share.

    The value of a Tyco common share at the time of the merger for purposes of
allocating the merger consideration will be determined by taking the average of
the volume weighted average sale prices per Tyco common share on the New York
Stock Exchange for the three consecutive trading days beginning on the date the
merger becomes effective.

    The following table illustrates the allocation of the merger consideration
for different values of a Tyco common share at the time of the merger and for
three different divisions between the percentage of Raychem common stock
electing cash and the percentage of Raychem common stock electing Tyco shares.
For simplicity, the table assumes that all Raychem stockholders have made
elections. The table also assumes that no Raychem stockholders have exercised
appraisal rights.

PROCEDURE FOR MAKING AN ELECTION
    Raychem stockholders can make their election to receive cash, Tyco common
shares or a combination of cash and Tyco common shares by delivering to the
exchange agent a completed election form included with this document together
with the certificates representing their shares and any other required
documentation specified in the election form. The election form, certificates
and other documentation must be received by the exchange agent no later than the
close of business on the last business day before the date the merger becomes
effective. Tyco and Raychem anticipate that the merger will be consummated on
the date that it is approved by Raychem stockholders. Accordingly, stockholders
who wish to make an election must assure that their materials are received by
the exchange agent no later than 5:00 p.m. Eastern Time on August 11, 1999, the
day before the special meeting.
    Tyco and Raychem do not intend to consummate the merger until all conditions
to the merger are satisfied, including receipt of all necessary regulatory
approvals. Both Tyco and Raychem expect to receive these approvals before the
August 12, 1999 special meeting. However, they cannot assure you that this will
be the case. If the merger is not consummated by August 19, 1999, Tyco and
Raychem will issue a press release on the Dow Jones News Service at least five
business days before consummating the merger. The press release will inform you
of the last date for submitting and/or changing your election forms. For a
discussion on the key regulatory approvals necessary for the merger, please see
"Certain Legal Matters" on page 39.
    Raychem stockholders who hold their shares in "street name" and who wish to
make an election will have to instruct their broker, dealer, bank or other
financial institution that holds their shares to make an election on their
behalf. For a more detailed description of the election procedures, see "Merger
Consideration--Making the Election" beginning on page 43.
                              THE MERGER (PAGE 18)
STOCKHOLDER VOTE REQUIRED
    The holders of a majority of the outstanding shares of Raychem common stock
must vote for the approval and adoption of the merger agreement to approve the
merger.

APPRAISAL RIGHTS

    Under Delaware law, any stockholder who does not wish to accept the
consideration provided for in the merger agreement has the right to demand
appraisal of, and to be paid the fair market value for, his or her shares of
Raychem common stock. The value of the Raychem common stock for this purpose
will exclude any element of value arising from the accomplishment or expectation
of the merger.

    In order for any Raychem stockholder to exercise his or her right to an
appraisal, the stockholder must deliver to Raychem before the special meeting a
written demand for an appraisal of his or her shares of Raychem common stock as
provided by Delaware law. Annex C contains the pertinent provisions of Delaware
law addressing appraisal rights.

    Raychem stockholders should particularly note the following:

    - simply voting against the adoption of the merger agreement will not be
      considered a demand for appraisal rights;

    - a stockholder who wishes to exercise appraisal rights must send a demand
      for appraisal to the Corporate Secretary of Raychem at MS 120-1A, 300
      Constitution Drive, Menlo Park, California 94025, which must be received
      before the vote at the special meeting; and

    - a stockholder who votes for approval of the merger will not have appraisal
      rights.

TAX TREATMENT

    It is a condition to the merger that Tyco and Raychem each receive an
opinion that the merger will qualify as a reorganization for United States
federal income tax purposes. Qualification as a reorganization depends in part

                                       4
<PAGE>
on the value of the Tyco common shares at the time the merger is effective
relative to the value of the overall merger consideration. If either tax opinion
is not rendered, Raychem may elect to require Tyco to proceed with the
acquisition of Raychem on a taxable basis.
    Provided the merger qualifies as a reorganization, in general for United
States federal income tax purposes:
    - Raychem stockholders who receive solely cash generally will recognize gain
      or loss with respect to the Raychem common stock they exchange;
    - Raychem stockholders who receive solely Tyco common shares will not
      recognize gain or loss in the merger, other than with respect to cash
      received in lieu of fractional shares; and
    - Raychem stockholders who receive cash and Tyco common shares will not
      recognize loss, other than with respect to cash received in lieu of
      fractional shares, but will recognize gain, if any, but not in excess of
      the cash received.
    If the acquisition of Raychem is consummated on a taxable basis, for United
States federal income tax purposes, Raychem stockholders will recognize gain or
loss with respect to the Raychem common stock they exchange.
    To review tax consequences of the merger in greater detail, see "Material
U.S. Federal Income Tax and Bermuda Tax Consequences" beginning on page 33.
INTERESTS OF OFFICERS AND DIRECTORS IN THE MERGER
    In considering the recommendation of the Raychem Board in favor of the
merger, stockholders should be aware that members of the Raychem Board and
Raychem management will receive benefits as a result of the merger that will be
in addition to or different from benefits received by Raychem stockholders
generally. For example, options held by members of the Raychem Board will become
vested in connection with the merger, and options and restricted stock held by
Raychem management that were scheduled to vest within the 12-month period
following consummation of the merger will become vested upon consummation of the
merger. In addition, under certain qualifying circumstances, members of Raychem
management will be entitled to receive severance benefits upon actual or
constructive termination of their employment following the merger. See
"Interests of Certain Persons in the Merger" beginning on page 31.

CONDITIONS OF THE MERGER

    The consummation of the merger depends upon satisfaction of a number of
conditions, including:

    - approval of the merger by the Raychem stockholders;

    - the absence of legal restraints to the consummation of the merger; and

    - receipt of opinions regarding the tax-free nature of the merger in respect
      of the Tyco common shares received. Raychem can elect to proceed with the
      acquisition on a taxable basis notwithstanding the failure to satisfy this
      condition. For further details, see "Conditions to the Merger--Failure to
      Deliver Tax Opinions" on page 56.

TERMINATION OF THE MERGER

    Either Raychem or Tyco may call off the merger if:

    - both parties consent in writing;

    - the merger is not completed by November 30, 1999 through no fault of the
      party seeking to call off the merger;

    - there exist legal restraints preventing the merger;

    - the Raychem stockholders do not approve the merger; or

    - the other party breaches in a material way its representations,
      warranties, covenants or agreements and that breach is not or cannot be
      remedied.

                                       5
<PAGE>
    In addition, Tyco may terminate the merger if the Board of Directors of
Raychem withdraws or adversely modifies its approval or recommendation of the
merger or recommends an alternative acquisition transaction with a third party.
Subject to certain conditions, Raychem may terminate the merger to accept an
acquisition proposal that is more favorable to Raychem and its stockholders than
the proposed merger with Tyco.
    For further details, see "Termination" beginning on page 56.
NO-SOLICITATION PROVISIONS; TERMINATION FEE AND EXPENSES
    Raychem has agreed that it will not solicit or encourage the initiation of
any inquiries or proposals regarding any alternative acquisition transactions
with third parties. Raychem may respond to unsolicited transaction proposals if
required by the Raychem Board's fiduciary duties. Raychem must promptly notify
Tyco if it receives a proposal for an alternative acquisition transaction. If
the merger is terminated under specified circumstances, generally involving an
alternative acquisition transaction, Raychem may be required to pay a
termination fee of $100 million to Tyco and reasonable out-of-pocket expenses of
up to $7.5 million to Tyco and Tyco (PA). Tyco may be required to pay reasonable
out-of-pocket expenses of up to $7.5 million to Raychem if the merger is
terminated under certain circumstances.
    See "Termination--Fees and Expenses," beginning on page 57, for a discussion
of the circumstances in which the fee and expenses are payable.
    In addition, Raychem may not redeem or amend its rights plan to permit or
facilitate an alternative acquisition transaction unless the merger agreement
has been terminated. See "No Solicitation" beginning on page 51.
    The termination fee and the no-solicitation provisions may have the effect
of discouraging persons who might be interested in entering into an acquisition
transaction with Raychem from proposing an alternative transaction.
ACCOUNTING TREATMENT
    The merger will be accounted for as a purchase by Tyco in accordance with
United States generally accepted accounting principles.

OPINION OF RAYCHEM'S FINANCIAL ADVISOR

    In determining that the merger is fair to and in the best interests of
Raychem and its stockholders, the Raychem Board considered an opinion from its
financial advisor, Morgan Stanley & Co. Incorporated, that, as of the date of
the opinion, the consideration to be received by the holders of Raychem common
stock pursuant to the merger agreement is fair from a financial point of view to
such holders. See "Opinion of Financial Advisor to Raychem" beginning on page
23. The full text of the written opinion of Morgan Stanley & Co. Incorporated is
attached as Annex B. WE ENCOURAGE YOU TO READ THIS OPINION.

                                  RISK FACTORS

    In evaluating the merger and the merger agreement, Raychem stockholders
should take into account the following factors:

FACTORS THAT RELATE TO THE MERGER CONSIDERATION

    THE VALUE OF THE MERGER CONSIDERATION THAT RAYCHEM STOCKHOLDERS WILL RECEIVE
WILL DEPEND ON THE VALUE OF TYCO COMMON SHARES AT THE TIME OF THE MERGER.

    In the merger, Raychem stockholders will receive cash, Tyco common shares or
a combination of cash and shares in exchange for their shares of Raychem common
stock. Whatever form of merger consideration a stockholder receives, the value
of the merger consideration will equal $18.50 plus the value of 0.2070 Tyco
common shares for each share of Raychem stock. The market value of Tyco shares
fluctuates based upon general market and economic conditions, Tyco's business
and prospects and other factors. Because the value of the merger consideration
depends on the value of a Tyco common share at the time of the merger, the value
that Raychem stockholders will receive in the merger cannot now be determined.
In particular, this value may be less than or greater than $37.00 per share of
Raychem stock, which is the value of the merger consideration based upon the
closing Tyco common share price of $89.375 on May 18, 1999, the last full
trading day prior to the announcement of the merger agreement.

    THE FORM OR MIX OF MERGER CONSIDERATION--CASH AND/OR TYCO SHARES--THAT A
RAYCHEM STOCKHOLDER RECEIVES MAY BE DIFFERENT FROM THE FORM OR MIX OF
CONSIDERATION THAT A STOCKHOLDER HAS ELECTED TO RECEIVE. RAYCHEM STOCKHOLDERS
WILL NOT KNOW THE ACTUAL FORM OR MIX OF MERGER CONSIDERATION THAT THEY WILL
RECEIVE AT THE TIME THEY VOTE ON THE MERGER.

    The total amount of cash and Tyco shares that will be paid to all Raychem
stockholders is fixed and will be allocated among stockholders according to
formulas discussed under "Merger Consideration--The Proration Rules" beginning
on page 45. The amount of cash, Tyco shares or combination of cash and Tyco
shares that a Raychem stockholder receives in the merger will depend on whether
the stockholder has submitted an election form, what the stockholder has elected
to receive and the elections made by all other stockholders. It will also depend
on the average of the volume weighted average sale prices per Tyco common share
on the New York Stock Exchange for the three consecutive trading days beginning
on the day the merger becomes effective. Accordingly, the form or mix of merger
consideration that a Raychem stockholder receives may be different from the form
or mix that he has elected to receive. A stockholder that has elected to receive
only cash could receive a combination of cash and Tyco shares, and a stockholder
that has elected to receive only Tyco shares could receive a combination of Tyco
shares and cash.

    If the merger qualifies as a reorganization for U.S. federal income tax
purposes, a Raychem stockholder that has elected to receive, and does in fact
receive, only Tyco shares will not be taxed, other than with respect to cash
received in lieu of fractional shares. If, however this stockholder receives a
combination of cash and Tyco shares, he will recognize gain, if any, to the
extent of the cash received. Similarly, a Raychem stockholder that has elected
to receive, and does in fact receive, only cash will be able to recognize any
loss he may have for tax purposes. If, however, this stockholder receives a
combination of cash and Tyco shares, he will not be able to recognize loss, if
any. If the acquisition of Raychem is consummated on a taxable basis, a Raychem
stockholder will recognize gain or loss regardless of the form or mix of merger
consideration that he receives.

    As discussed under "Merger Consideration--Making the Election" beginning on
page 43, the allocation of the merger consideration cannot be determined until
after the the merger is consummated. Therefore, Raychem stockholders will not
know the actual form or mix of consideration they will receive at the time they
vote on the merger.

                                       7
<PAGE>
    THE VALUE THAT ALL RAYCHEM STOCKHOLDERS ARE ENTITLED TO RECEIVE IS INTENDED
TO BE THE SAME, REGARDLESS OF WHETHER THEY RECEIVE CASH OR STOCK. HOWEVER, THE
VALUE OF THE CONSIDERATION RECEIVED BY STOCKHOLDERS MAY DIFFER AT THE TIME THE
MERGER CONSIDERATION IS ACTUALLY PAID BECAUSE OF FLUCTUATIONS IN THE TYCO SHARE
PRICE.

    The value of the merger consideration Raychem stockholders receive is
intended to be the same whether a stockholder receives cash, Tyco common shares
or a combination of cash and Tyco shares. This equivalence is based upon the
average of the three trading day volume weighted average sale prices per Tyco
common share referred to above. The market value of a Tyco common share on the
date the merger consideration is paid to a Raychem stockholder is likely to be
different from this volume weighted average value. Thus, the value of the merger
consideration, as determined on the dates that Raychem stockholders actually
receive the merger consideration, is likely to differ depending upon the mix of
cash and/or Tyco shares received by each stockholder.

    RAYCHEM COULD ELECT TO REQUIRE TYCO TO PROCEED WITH THE ACQUISITION OF
RAYCHEM EVEN THOUGH IT WOULD NOT QUALIFY FOR TAX-FREE TREATMENT WITH RESPECT TO
THE STOCK CONSIDERATION.

    The merger is intended to qualify as a reorganization for U.S. federal
income tax purposes, resulting in tax-free treatment with respect to the stock
consideration received. Qualification as a reorganization depends in part on the
value of the Tyco common shares at the time the merger becomes effective
relative to the value of the overall merger consideration. If the tax advisor to
either Tyco or Raychem cannot deliver its opinion that the merger will qualify
as a reorganization, Raychem may nonetheless elect to require Tyco to proceed
with the acquisition of Raychem on a taxable basis. Whether the tax advisors are
prepared to deliver their opinions may not be known at the time of the
stockholder vote on the merger. Raychem does not expect to submit its
determination of whether to proceed with the acquisition by Tyco in the absence
of the tax opinions to a separate vote of stockholders. If Raychem elects to
proceed even though Tyco's acquisition of Raychem does not qualify as a
reorganization, Raychem stockholders will recognize all of the gain or loss with
respect to their Raychem common stock exchanged in the acquisition, even though
such stockholders may receive Tyco common shares in the exchange.

OTHER FACTORS

    THE RIGHTS OF SHAREHOLDERS OF TYCO UNDER BERMUDA LAW ARE NOT AS FAVORABLE IN
SOME WAYS AS THE RIGHTS OF STOCKHOLDERS OF RAYCHEM UNDER DELAWARE LAW.

    - Shareholders may not be able to obtain jurisdiction over Tyco outside
      Bermuda, so that certain remedies available to stockholders of Raychem,
      such as class action lawsuits under United States federal and Delaware
      law, might not be available to Tyco shareholders.

    - The right to bring a derivative action in the name of the company for a
      wrong to a company committed by present or former directors of the company
      is more limited under Bermuda law than under Delaware law.

    - Under Bermuda law and Tyco's bye-laws, only shareholders holding 5% or
      more of the outstanding Tyco shares or numbering 100 or more may propose a
      resolution at a Tyco general meeting. Raychem stockholders do not have to
      satisfy these requirements to propose a resolution at a Raychem
      stockholders meeting.

    Report on Form 8-K filed on June 3, 1999 which is incorporated in this
    document by reference.

(2) Operating income in the fiscal year ended September 30, 1998 includes
    charges of $80.5 million primarily related to costs to exit certain
    businesses in US Surgical's operations and restructuring charges of $12.0
    million related to the operations of US Surgical. In addition, Tyco recorded
    restructuring charges of $185.8 million in connection with AMP's profit
    improvement plan and a credit of $21.4 million to restructuring charges
    related to the execution of AMP's 1996 restructuring plans. See Note 16 to
    the Supplemental Consolidated Financial Statements contained in Tyco's
    Current Report on Form 8-K filed on June 3, 1999.

(3) In September 1997, Tyco changed its fiscal year end from December 31 to
    September 30. Accordingly, the nine-month transition period ended September
    30, 1997 is presented.

(4) On July 2, 1997, Tyco, formerly called ADT Limited, merged with Tyco
    International Ltd., a Massachusetts corporation ("Former Tyco"). On August
    27, 1997, August 29, 1997, October 1, 1998 and April 2, 1999, Tyco merged
    with INBRAND Corporation, Keystone, US Surgical and AMP, respectively. These
    five combinations are more fully described in Notes 1 and 2 to the
    Supplemental Consolidated Financial Statements contained in Tyco's Current
    Report on Form 8-K filed on June 3, 1999. Operating income in the nine
    months ended September 30, 1997 includes charges related to merger,
    restructuring and other non-recurring costs of $917.8 million and impairment
    of long-lived assets of $148.4 million primarily related to the mergers and
    integration of ADT, Former Tyco, Keystone and INBRAND, and charges of $24.3
    million for litigation and other related costs and $5.8 million for
    restructuring charges in US Surgical's operations. See Notes 11 and 16 to
    the Supplemental Consolidated Financial Statements contained in Tyco's
    Current Report on Form 8-K filed on June 3, 1999. The results for the nine
    months ended September 30, 1997 also include a charge of $361.0 million for
    the write-off of purchased in-process research and development related to
    the acquisition of the submarine systems business of AT&T Corp.

(5) Prior to their respective mergers, ADT, Keystone, US Surgical and AMP had
    December 31 fiscal year ends and Former Tyco had a June 30 fiscal year end.
    The selected consolidated financial data have been combined using a December
    31 fiscal year end for ADT, Keystone, Former Tyco, US Surgical and AMP for
    the year ended December 31, 1996. For 1995 and 1994, the results of
    operations and financial position reflect the combination of ADT, Keystone,
    US Surgical and AMP with a December 31 fiscal year end and Former Tyco with
    a June 30 fiscal year end. Net sales and net income for Former Tyco for the
    period July 1, 1995 through December 31, 1995, which results are not
    included in the historical combined results, were $2.46 billion and $136.4
    million, respectively.

(6) Operating income in 1996 includes non-recurring charges of $744.7 million
    related to the adoption of Statement of Financial Accounting Standards No.
    121, $237.3 million related principally to the restructuring of ADT's
    electronic security services business in the United States and United
    Kingdom, $98.0 million to exit various product lines and manufacturing
    operations associated with AMP's operations and $8.8 million of fees and
    expenses related to ADT's acquisition of Automated Security (Holdings) plc,
    a United Kingdom company. See Notes 11 and 16 to the Supplemental
    Consolidated Financial Statements contained in Tyco's Current Report on Form
    8-K filed on June 3, 1999.

(7) Operating income in 1995 includes a loss of $65.8 million on the disposal of
    the European auto auction business and a gain of $31.4 million from the
    disposal of the European electronic article surveillance business. Operating
    income also includes non-recurring charges of $97.1 million for
    restructuring charges at ADT and Keystone and for the fees and expenses
    related to the 1994 merger of Kendall International, Inc. and Former Tyco,
    as well as a charge of $8.2 million relating to the divestiture of certain
    assets by Keystone.

(8) Per share amounts have been retroactively restated to give effect to the
    mergers with Former Tyco, Keystone, INBRAND, US Surgical and AMP, a 0.48133
    reverse stock split effected on July 2, 1997, and a two-for-one stock split
    distributed on October 22, 1997, effected in the form of a stock dividend.

(9) Tyco has paid a quarterly dividend of $0.025 per common share since July 2,
    1997, the date of the Former Tyco/ADT merger. ADT had not paid any dividends
    on its common shares since 1992. Prior to the merger with ADT, Former Tyco
    paid a quarterly cash dividend of $0.025 per share of common stock since
    January 1992. US Surgical paid quarterly dividends of $0.04 per share in the
    year ended September 30, 1998 and the nine months ended September 30, 1997
    and aggregate dividends of $0.08 per share in 1996, 1995 and 1994. AMP paid
    dividends of $0.27 per share in the quarter ended March 31, 1999 and in each
    of the four quarters during calendar 1998, $0.26 per share in each of the
    four quarters during calendar 1997, and aggregate dividends of $1.00 per
    share in 1996, $0.92 per share in 1995 and $0.84 per share in 1994. The
    payment of dividends by Tyco in the future will be determined by Tyco's
    Board and will depend on business conditions, Tyco's financial condition and
    earnings and other factors.

    The special meeting of Raychem's stockholders will be held at 10:00 a.m.

PURPOSE OF THE RAYCHEM SPECIAL MEETING

    At the special meeting, Raychem stockholders will consider and vote upon a
proposal to approve and adopt the Agreement and Plan of Merger and
Reorganization, dated as of May 19, 1999, among Raychem, Tyco and Tyco (PA). The
merger agreement provides, among other things, that Raychem will be merged with
Tyco (PA), and each outstanding share of Raychem common stock will be converted
into the right to receive a fraction of a Tyco common share, cash or a
combination of shares and cash.

RECORD DATE, VOTING RIGHTS, QUORUM AND REQUIRED VOTE

    The close of business on July 7, 1999 is the record date for determining the
holders of Raychem common stock who are entitled to receive notice of and to
vote at the special meeting or at any adjournment of the special meeting.

    Raychem has only one class of capital stock outstanding, which is common
stock, par value $1.00 per share. Each holder of Raychem common stock
outstanding on the record date is entitled to one vote for each share held. The
holders of a majority of the outstanding shares of Raychem common stock entitled
to vote must be present at the special meeting, in person or by proxy, to
constitute a quorum to transact business.

    The holders of a majority of the outstanding shares of Raychem common stock
must vote for the approval and adoption of the merger agreement to approve the
merger. On the record date, 77,800,919 shares of Raychem common stock were
outstanding, held by approximately 1,907 holders of record.

    The Raychem Board has unanimously approved the merger. The Tyco Board has
approved the merger and the issuance of Tyco common shares for delivery in
connection with the merger. See "Background of the Merger" beginning on page 18.
Bermuda law does not require that Tyco shareholders approve the merger. Tyco, as
the sole shareholder of Tyco (PA), has approved the merger.

RECOMMENDATION OF THE BOARD OF DIRECTORS OF RAYCHEM

    THE BOARD OF DIRECTORS OF RAYCHEM HAS UNANIMOUSLY DETERMINED THAT THE MERGER
IS FAIR TO AND IN THE BEST INTERESTS OF RAYCHEM AND ITS STOCKHOLDERS AND
UNANIMOUSLY RECOMMENDS THAT YOU VOTE FOR THE APPROVAL AND ADOPTION OF THE MERGER
AGREEMENT. See "Recommendation of the Board of Directors of Raychem" beginning
on page 21 and "Interests of Certain Persons in the Merger" beginning on page
31.

PROXIES AND REVOCATION

    A proxy card is enclosed for use by Raychem stockholders. The Board of
Directors of Raychem requests that stockholders SIGN AND RETURN THE PROXY CARD
IN THE ACCOMPANYING ENVELOPE. No postage is required if mailed within the United
States. IF YOU HAVE QUESTIONS OR REQUESTS FOR ASSISTANCE IN COMPLETING AND
SUBMITTING PROXY CARDS, PLEASE CONTACT GEORGESON & COMPANY INC., A FIRM THAT
PROVIDES PROFESSIONAL PROXY SOLICITING SERVICES THAT RAYCHEM HAS RETAINED, AT
THE FOLLOWING ADDRESS AND TELEPHONE NUMBER:

<PAGE>
    All properly executed proxies that are not revoked will be voted at the
special meeting as instructed on those proxies. A stockholder who executes and
returns a proxy may revoke it at any time before it is voted, but only by
executing and returning a proxy bearing a later date, by giving written notice
of revocation to the Corporate Secretary of Raychem, or by attending the special
meeting and voting in person. A proxy that has been properly executed, but has
otherwise been left blank, will be voted for approval of the merger, unless the
proxy is revoked before the vote is taken. Abstentions will be treated as shares
present in determining whether Raychem has a quorum for the special meeting, but
abstentions will have the same effect as a vote against approval of the merger.
If a broker or other record holder or nominee indicates on a proxy that it does
not have direction or authority to vote certain shares, those shares will be
considered present at the special meeting for purposes of determining a quorum
but will have the same effect as a vote against approval of the merger.

SOLICITATION OF PROXIES

    The solicitation of the enclosed proxies from Raychem stockholders is made
on behalf of the Board of Directors of Raychem. The expenses of the solicitation
of proxies, including preparing, handling, printing and mailing the proxy
soliciting material, will be borne by Raychem. Solicitation will be made by
mail, by electronic telecommunications or in person. Raychem has retained the
services of Georgeson & Company Inc. to assist in the solicitation of proxies
for a fee estimated at $10,000 plus out-of-pocket expenses. Management of
Raychem may also use the services of its directors, officers and employees in
soliciting proxies, who will not receive any additional compensation therefor,
but who will be reimbursed for their out-of-pocket expenses. Raychem will
reimburse banks, brokers, nominees, custodians and other fiduciaries for their
expenses in forwarding copies of the proxy soliciting material to the beneficial
owners of the stock held by such persons and in requesting authority for the
execution of proxies and election forms.

                                   THE MERGER

    This section, as well as the next section, "The Merger Agreement," describes
the material aspects of the proposed merger. These discussions are qualified in
their entirety by reference to the merger agreement, which is attached as an
Annex to this document, and to the other agreements and documents that are
discussed in this document and that are filed as exhibits to the registration
statement of which this document forms a part. YOU SHOULD READ THE MERGER
AGREEMENT IN ITS ENTIRETY AS IT IS THE LEGAL DOCUMENT THAT GOVERNS THE MERGER.

BACKGROUND OF THE MERGER

    Richard A. Kashnow, Chairman of the Board and Chief Executive Officer of
Raychem, and L. Dennis Kozlowski, Chairman of the Board and Chief Executive
Officer of Tyco, have known each other since 1994 and since that time have been
members of the Board of Directors of Applied Power, Inc. As a result, in
December 1998 and January 1999, Dr. Kashnow and Mr. Kozlowski discussed various
matters relating to the businesses of Raychem and AMP. In November 1998, a
subsidiary of Tyco entered into a merger agreement to acquire AMP.

    Following such discussions, in early March 1999, Dr. Kashnow and Mr.
Kozlowski agreed to meet to discuss on a preliminary basis whether Tyco and
Raychem should explore a possible business combination transaction.

    On March 21 and 22, 1999, Dr. Kashnow and Mr. Kozlowski, together with
Raymond J. Sims, Chief Financial Officer of Raychem, and Mark H. Swartz, Chief
Financial Officer of Tyco, met to discuss Raychem's and Tyco's businesses. The
group preliminarily determined in their discussions that Raychem's and Tyco's
businesses were complementary in nature and that cost savings and the ability to
market a broader line of products to their customers might result from, among
other things, a business combination of Raychem and Tyco. Dr. Kashnow and Mr.
Kozlowski concluded that they would ask Tyco and Raychem representatives to
further explore the benefits and risks of a possible combination. On March 21,
1999, Raychem and Tyco entered into a confidentiality agreement on customary
terms and conditions.

    On March 24, 1999, the Raychem Board met and, among other things, received a
report from Dr. Kashnow on the meetings.

    During the last week of March, representatives of Raychem and Tyco met to
discuss their respective business and operations and potential cost savings and
synergies that might result from a business combination. Based on such
discussions, Dr. Kashnow and Mr. Kozlowski determined that it was advisable to
continue to explore whether a business combination was in the best interests of
Raychem's and Tyco's stockholders.

    Dr. Kashnow and Mr. Kozlowski continued discussions in early April 1999 with
a view to exploring preliminary transaction structures, the form of
consideration to be received by the holders of Raychem common stock and a range
of values to be paid by Tyco for the shares of Raychem common stock.

    On April 7, 1999, the Raychem Board met and Dr. Kashnow updated the board on
the status of the exploratory discussions. Also, at such meeting, the Raychem
Board continued its periodic review of Raychem's general strategic alternatives.
To assist the Raychem Board in its review, Morgan Stanley & Co. Incorporated,
financial advisor to Raychem, made a presentation to the Raychem Board relating
principally to Raychem's general business, financial performance and general
strategic alternatives.

    On April 14, 1999, Dr. Kashnow and Mr. Kozlowski met to discuss further the
potential transaction and instructed representatives of Raychem and Tyco,
respectively, to coordinate due diligence reviews. During the middle of April
1999, representatives of Raychem and Tyco planned due

                                       18
<PAGE>
diligence reviews of the respective companies and began comprehensive business,
financial, accounting and legal due diligence reviews of the other company.

    On April 29, 1999, the Raychem Board met and, among other things, discussed
the progress of the due diligence reviews and the status of the parties' efforts
to determine whether a business combination was desirable. Due diligence reviews
continued during early May 1999. In the course of their investigation, Tyco
personnel reviewed documentation and conducted discussions with Raychem, its
accountants and other Raychem representatives concerning Raychem's financial
condition, facilities, operations, human resources programs, intellectual
property, tax posture, environmental compliance and other business and legal
matters. Raychem's representatives conducted a similar due diligence review of
Tyco.

    On May 7, 1999, the Raychem Board met again and received a report from Dr.
Kashnow concerning the status of the due diligence reviews and the preliminary
discussions between Tyco and Raychem regarding the possible structures and terms
of a business combination transaction.

    Dr. Kashnow and Mr. Kozlowski, together with representatives of Tyco and
Raychem, met on May 11, 1999 to discuss, among other things, possible
transaction structures, the form of consideration to be paid to Raychem
stockholders and the range of per share value to be paid to holders of Raychem
common stock. On May 11, 1999, the Raychem Board met to review the status of the
discussions with Tyco. Dr. Kashnow described the transaction structures, the
form of consideration and the range of per share consideration values being
discussed by Raychem, Tyco and their respective representatives.

    On May 12, 1999, with due diligence continuing, Tyco delivered to Raychem an
initial draft of a merger agreement. On that same day, Tyco's Board of Directors
met in Bermuda to discuss a potential transaction with Raychem. The Tyco Board
determined a merger transaction with Raychem was in the best interests of Tyco's
shareholders and authorized Tyco's officers to complete the transaction within
certain parameters. Beginning on May 14, 1999, legal representatives of Raychem
and Tyco held numerous discussions regarding the terms and conditions of the
proposed merger agreement and various other legal, financial, accounting and
regulatory issues including, among other things, the treatment of Raychem's
employee benefit plans, the identification of required regulatory filings and
the tax treatment of the proposed transaction. These discussions continued
through May 16, 1999. Also, during such period, representatives of Tyco and
Raychem discussed on a number of occasions a range of values to be paid on a per
share basis to holders of Raychem common stock.

    During the morning of May 17, 1999, the Raychem Board met to review the
terms of the proposed merger. Representatives of Morgan Stanley made a
presentation regarding the financial terms of the proposed merger and discussed,
among other things, with the Raychem Board the financial performance of Raychem
and Tyco. Raychem's outside legal counsel also reviewed with the Raychem Board
certain legal matters, including a detailed review of the merger agreement, and
discussed with the Raychem Board the Board's fiduciary duties in the context of
the proposed transaction and other relevant aspects of applicable law. Following
such presentations and discussions, the Raychem Board authorized senior
management to continue to pursue the proposed merger.

    Throughout the day on May 17, 1999, the management teams of Raychem and
Tyco, together with their advisors, continued to discuss various issues,
including those relating to employee benefits, the rights of a party to
terminate the merger agreement and whether any payment would be due as a result
of a termination of the merger agreement under certain circumstances.

    The Raychem Board met again on May 18, 1999 to continue its discussions
regarding the merger and to further review the terms and conditions of the
proposed merger with senior management, outside legal counsel and Morgan
Stanley. During this meeting, the Raychem Board received the opinion of Morgan
Stanley that, as of such date, the consideration to be received by the holders
of Raychem common stock pursuant to the merger agreement is fair from a
financial point of view to

                                       19
<PAGE>
such holders. Following further discussions, the Raychem Board unanimously
determined that the merger is fair to, and in the best interests of, Raychem and
its stockholders, approved the merger and the merger agreement, and resolved to
recommend that the stockholders of Raychem vote to approve and adopt the merger
agreement.

    The merger agreement was signed by Raychem and Tyco early in the morning on
May 19, 1999. Later that morning, prior to commencement of trading on the NYSE,
the companies issued a joint press release announcing the execution of the
merger agreement.

EXCHANGE OF FINANCIAL FORECASTS

    As part of their respective business planning cycles, management of each of
Tyco and Raychem from time to time have prepared internal financial forecasts
regarding their respective anticipated future operations. In the course of the
discussions described in "Background of the Merger," each of Tyco and Raychem
provided certain of these internal forecasts to the other and to the other's
financial advisor.

    The internal financial forecasts regarding Raychem prepared by Raychem's
management reflected the following forecasted information, prior to
restructuring charges announced on June 8, 1999 and expenses related to the
merger:

<TABLE>

</TABLE>

    The internal financial forecasts regarding Tyco prepared by Tyco's
management reflected the following forecasted information for Tyco's fiscal year
1999. The forecast includes Tyco results, without AMP, through March 31, 1999
and the expected results, including AMP, for the balance of fiscal 1999,
excluding restructuring and other non-recurring charges:

$  19.4 billion  $ 2.3 billion  $    3.00
</TABLE>

    Raychem's and Tyco's forecasts were prepared for internal budgeting and
planning purposes only and not with a view to public disclosure or compliance
with published guidelines of the SEC or the guidelines established by the
American Institute of Certified Public Accountants regarding projections or
forecasts. While presented with numerical specificity, the forecasts are based
upon a variety of assumptions relating to the business of the respective
companies and are inherently subject to significant uncertainties and
contingencies that are beyond the control of the managements of Raychem or Tyco.
These include the impact of general economic and business conditions, the
competitive environment in which each operates and other factors. See "Forward
Looking Information" on page 9. Accordingly, actual results may differ
materially from those forecasted.

    The inclusion of the forecasts in this document should not be regarded as a
representation by Raychem or Tyco that such forecasts are or will prove to be
correct. As a matter of course, neither Raychem nor Tyco makes public
projections or forecasts of its anticipated financial position or results of
operations. Except to the extent required under applicable securities laws,
neither Raychem nor Tyco intends to make publicly available any update or other
revisions to any of the forecasts to reflect circumstances existing after the
respective dates of preparation of such forecasts.

RECOMMENDATION OF THE BOARD OF DIRECTORS OF RAYCHEM; REASONS OF RAYCHEM FOR THE
  MERGER

    The Raychem Board, after careful consideration, has unanimously:

    1.  determined that the merger is fair to and in the best interests of
       Raychem and its stockholders;

    2.  approved the merger and the merger agreement; and

    3.  recommended that holders of shares of Raychem common stock vote for the
       approval and adoption of the merger agreement.

    At a meeting held on May 18, 1999, the Raychem Board, with the assistance of
Raychem's outside financial and legal advisors, considered the legal, financial
and other terms of the merger.

    In determining that the merger is fair to and in the best interests of
Raychem and its stockholders, the Raychem Board considered a number of factors
and potential benefits, including, without limitation, the following:

    - the opportunity for Raychem stockholders to receive a significant premium
      over the market price for shares of Raychem common stock existing prior to
      the public announcement of the merger;

    - the ability of Raychem stockholders to continue to participate in the
      growth of the business conducted by Tyco and Raychem after the merger and
      to benefit from the potential appreciation in the value of Tyco common
      shares by electing to receive Tyco common shares;

    - the qualification of the merger as a reorganization for U.S. federal
      income tax purposes, which will result in the exchange of shares of
      Raychem common stock for Tyco common shares or for a combination of Tyco
      common shares and cash, except to the extent of cash received, being tax-
      free for U.S. federal income tax purposes;

    - the financial condition, results of operations and business of Raychem and
      Tyco, on both an historical and prospective basis, and current industry,
      economic and market conditions;

    - the historical market prices and recent trading patterns of Raychem common
      stock and Tyco common shares and market prices, recent trading patterns
      and financial data relating to other companies engaged in the same
      businesses as Raychem and Tyco;

    - the possible strategic growth opportunities that might be available to
      Raychem absent the merger and the belief, based on review of such
      opportunities, that stockholders of Raychem would benefit most from the
      potential business combination with Tyco to the extent they receive Tyco
      common shares;

    - the larger public float and trading volume of Tyco common shares compared
      to the public float and trading volume of shares of Raychem common stock,
      which would provide Raychem stockholders the opportunity to gain greater
      liquidity in their investment to the extent they receive Tyco common
      shares;

    - the review of, and discussions with, Raychem senior management, legal and
      financial advisors, regarding certain business, financial, legal and
      accounting aspects of the merger, the results of legal and financial due
      diligence and a review of the terms of and conditions to the merger;

    - the analysis and recommendation of Raychem's management that the merger be
      approved, including, without limitation, a discussion of the complementary
      nature of certain product lines of Raychem and Tyco;

                                       21
<PAGE>
    - the belief, based on presentations by Raychem's legal and financial
      advisors, that the terms of the merger agreement, including the limited
      conditions to Tyco's obligation to close the merger and the ability of
      Raychem to consider proposed alternative business combinations under
      certain circumstances, are generally customary for transactions such as
      the merger; and

    - the fairness opinion of Morgan Stanley & Co. Incorporated to the effect
      that, as of the date of such opinion and based upon and subject to certain
      matters stated therein, the consideration to be received by the holders of
      shares of Raychem common stock pursuant to the merger agreement was fair
      from a financial point of view to such holders.

    The Raychem Board also considered and balanced against the potential
benefits of the merger a number of potentially negative factors, including,
without limitation, the following:

    - the risk that the merger would not be consummated;

    - the possibility that the market value of Tyco common shares might
      decrease, which would result in less aggregate value paid to Raychem
      stockholders;

    - the fact that stockholders of Raychem will not receive the full benefit of
      any future growth in the value of their equity that Raychem may have
      achieved as an independent company, and the potential disadvantage to
      Raychem stockholders who receive Tyco common shares in the event that Tyco
      does not perform as well in the future as Raychem may have performed as an
      independent company;

    - the substantial management time and effort that will be required to
      consummate the merger and integrate the operations of the two companies;

    - the possibility that certain provisions of the merger agreement,
      including, among others, the no solicitation and termination fee payment
      provisions of the merger agreement, might have the effect of discouraging
      other persons potentially interested in merging with or acquiring Raychem
      from pursuing such an opportunity or, if pursued, from announcing and
      thereafter consummating such a transaction prior to November 30, 2000;

    - the possibility that the tax-free treatment with respect to the exchange
      of shares of Raychem common stock may not be available under certain
      circumstances; and

    - other matters described under "Risk Factors" beginning on page 7.

    After detailed consideration of these factors, the Raychem Board concluded
that the potential benefits of the merger outweighed these considerations and
determined that the merger was fair to and in the best interests of Raychem and
its stockholders.

    The above discussion of the information and factors considered by the
Raychem Board is not exhaustive and does not include all factors considered by
the Raychem Board. In view of the variety of factors considered in connection
with its evaluation of the merger, the Raychem Board did not find it practicable
to, and did not, quantify or otherwise assign relative weights to the specific
factors considered in reaching its determination. In addition, individual
members of the Raychem Board may have given different weights to different
factors. Based on the factors outlined above, the Raychem Board determined that
the merger is fair to and in the best interests of Raychem and its stockholders.

    THE RAYCHEM BOARD HAS UNANIMOUSLY DETERMINED THAT THE MERGER IS FAIR TO AND
IN THE BEST INTERESTS OF RAYCHEM AND ITS STOCKHOLDERS AND UNANIMOUSLY RECOMMENDS
THAT YOU VOTE FOR THE APPROVAL AND ADOPTION OF THE MERGER AGREEMENT.

Advisor to Raychem" beginning on page 23, "Material U.S. Federal Income Tax and
Bermuda Tax Consequences" beginning on page 33 and "Comparative Per Share Prices
and Dividends" beginning on page 60.

OPINION OF FINANCIAL ADVISOR TO RAYCHEM

    Pursuant to a letter agreement dated as of March 24, 1999, Morgan Stanley
was engaged to provide Raychem with financial advisory services and a financial
fairness opinion in connection with the merger. Morgan Stanley was selected by
the Raychem Board to act as Raychem's financial advisor based on Morgan
Stanley's qualifications, expertise and reputation and its knowledge of the
business and affairs of Raychem. At the meeting of the Raychem Board on May 18,
1999, Morgan Stanley rendered its oral opinion, subsequently confirmed in
writing, that as of May 18, 1999, based upon and subject to the various
considerations set forth in the opinion, the consideration to be received by
holders of Raychem common stock pursuant to the merger agreement was fair from a
financial point of view to the holders of Raychem common stock.

    THE FULL TEXT OF THE WRITTEN OPINION OF MORGAN STANLEY, DATED MAY 18, 1999,
WHICH SETS FORTH, AMONG OTHER THINGS, ASSUMPTIONS MADE, PROCEDURES FOLLOWED,
MATTERS CONSIDERED AND LIMITATIONS ON THE SCOPE OF THE REVIEW UNDERTAKEN BY
MORGAN STANLEY IN RENDERING ITS OPINION, IS ATTACHED AS ANNEX B TO THIS
DOCUMENT. RAYCHEM STOCKHOLDERS ARE URGED TO, AND SHOULD, READ THE OPINION
CAREFULLY AND IN ITS ENTIRETY. MORGAN STANLEY'S OPINION IS DIRECTED TO THE
RAYCHEM BOARD AND ADDRESSES ONLY THE FAIRNESS OF THE CONSIDERATION TO BE
RECEIVED BY HOLDERS OF RAYCHEM COMMON STOCK PURSUANT TO THE MERGER AGREEMENT
FROM A FINANCIAL POINT OF VIEW AS OF THE DATE OF THE OPINION; IT DOES NOT
ADDRESS ANY OTHER ASPECT OF THE MERGER AND DOES NOT CONSTITUTE A RECOMMENDATION
TO ANY HOLDER OF RAYCHEM COMMON STOCK AS TO HOW TO VOTE AT THE RAYCHEM SPECIAL
MEETING. THE SUMMARY OF THE OPINION OF MORGAN STANLEY SET FORTH IN THIS DOCUMENT
IS QUALIFIED IN ITS ENTIRETY BY REFERENCE TO THE FULL TEXT OF SUCH OPINION.

    In connection with rendering its opinion, Morgan Stanley, among other
things:

    - reviewed certain publicly available financial statements and other
      information of Raychem and Tyco;

    - reviewed certain internal financial statements and other financial and
      operating data concerning Raychem prepared by the management of Raychem;

      operating data concerning Tyco prepared by the management of Tyco;

    - analyzed certain financial projections prepared by the management of
      Raychem;

    - analyzed certain financial projections prepared by the management of Tyco;

    - discussed the past and current operations and financial condition and the
      prospects of Raychem, including information relating to certain strategic,
      financial and operational benefits anticipated from the merger, with
      senior executives of Raychem;

    - discussed the past and current operations and financial condition and the
      prospects of Tyco, including information relating to certain strategic,
      financial and operational benefits anticipated from the merger, with

    - reviewed the reported prices and trading activity for Raychem common stock
      and Tyco common shares;

      trading activity of Raychem common stock and Tyco common shares with that
      of certain other publicly traded companies and their securities;

    - reviewed the financial terms, to the extent publicly available, of certain
      comparable acquisition transactions;

                                       23
<PAGE>
    - reviewed the merger agreement and certain related agreements; and

    - performed such other analyses and considered such other factors as Morgan
      Stanley deemed appropriate.

    Morgan Stanley has assumed and relied upon, without independent
verification, the accuracy and completeness of the information reviewed by it
for the purposes of this opinion. With respect to the internal financial
statements and other financial and operating data and discussions relating to
strategic, financial and operational benefits anticipated from the merger
provided by Raychem, Morgan Stanley has assumed that they have been reasonably
prepared on bases reflecting the best currently available estimates and
judgments of the prospects of Raychem. Morgan Stanley has relied upon, without
independent verification, the following:

    - the assessment by the management of Raychem of the cost savings and
      benefits expected to result from the merger; and

    - the assumption that the merger will be consummated in accordance with the
      terms set forth in the merger agreement, including, among other things,
      that the exchange of Raychem common stock for Tyco common shares or for a
      combination of Tyco common shares and cash, except to the extent of cash
      received, will be tax-free for U.S. federal income tax purposes.

    Morgan Stanley did not make any independent valuation or appraisal of the
assets or liabilities of Raychem, nor has it been furnished with any such
appraisals. Morgan Stanley's opinion is necessarily based on financial,
economic, market and other conditions as in effect on, and the information made
available to it as of, the date of its opinion.

    The following is a brief summary of certain of the analyses performed by
Morgan Stanley in connection with its oral opinion and the preparation of its
opinion letter dated May 18, 1999. Certain of these summaries of financial
analyses include information presented in tabular format. In order to fully
understand the financial analyses used by Morgan Stanley, the tables must be
read together with the text of each summary. The tables alone do not constitute
a complete description of the financial analyses.

with publicly available information for the Specialty Chemical Companies, the
Telecom Equipment Companies and the Connectors Companies. For this analysis,
Morgan Stanley examined median estimates from securities research analysts,
where appropriate. The following table presents, as of May 17, 1999, the median
for these groups of the following statistics:

    - the ratio of price to calendar year 2000 estimated earnings per share,
      commonly known as EPS;

    - the ratio of aggregate value, defined as market capitalization plus total
      debt less cash and cash equivalents, to:

     1.  latest twelve months of revenue,

     2.  estimated calendar year 1999 revenue,

     3.  last twelve months of earnings before interest, taxes, depreciation and
         amortization, commonly known as EBITDA;

     4.  estimated calendar year 1999 EBITDA; and

    - five year projected EPS growth rates.

The analyses reflected in the table above show that as of May 17, 1999:

    - Raychem's common stock price was 13.4 times estimated calendar year 2000
      EPS, as compared to the comparable ratios for the Specialty Chemical,
      Telecom Equipment and Connectors groups of 14.8, 27.6 and 21.9,
      respectively;

    - Raychem's aggregate value was 1.5 times its last twelve months of revenue,
      as compared to the comparable ratios for the Specialty Chemical, Telecom
      Equipment and Connectors groups of 1.0, 3.2 and 1.6, respectively;

    - Raychem's aggregate value was 1.4 times management's estimated revenue for
      calendar year 1999, as compared to the comparable ratios for the Specialty
      Chemical, Telecom Equipment and Connectors groups of 1.0, 3.0 and 1.3,
      respectively;

    - Raychem's aggregate value was 9.4 times its last twelve months of EBITDA,
      as compared to the comparable ratios for the Specialty Chemical, Telecom
      Equipment and Connectors groups of 7.9, 18.9 and 8.7, respectively.

    - Raychem's aggregate value was 7.9 times its EBITDA for calendar year 1999
      as compared to the comparable ratios for the Specialty Chemical, Telecom
      Equipment and Connectors groups of 7.7, 16.3 and 8.5, respectively; and

    - Raychem's projected EPS growth rate over the next five years was 15% as
      compared to the median projected EPS growth rates for the Specialty
      Chemical, Telecom Equipment and Connectors groups of 11%, 25% and 17%,
      respectively.

Such analyses also showed that as of May 17, 1999, the Tyco common share price
to estimated calendar year 2000 earnings was 21.8 times, compared to a median of
20.5 times for the Tyco Comparable Companies. Tyco's aggregate value was 5.8
times last twelve months of revenue, compared to a median of 2.1 for the Tyco
Comparable Companies, and Tyco's aggregate value was 3.5 times estimated
calendar year 1999 revenue compared to a median of 1.9 times for Tyco Comparable
Companies. Tyco's aggregate value was 24.1 times last twelve months of EBITDA,
compared to a median of 12.1 for the Tyco Comparable Companies, and Tyco's
aggregate value was 15.4 times calendar year 1999 EBITDA compared to a median of
11.4 times for the Tyco Comparable Companies. Lastly, Tyco's projected growth
rate was 20.0%, compared to a median of 13.5% for the Tyco Comparable Companies.

    No company utilized in the peer group comparison analysis as a comparison is
identical to either Raychem or Tyco. In evaluating the peer groups, Morgan
Stanley made judgments and assumptions with regard to industry performance,
general business, economic, market and financial conditions and other matters,
many of which are beyond the control of either Raychem or Tyco, such as the
impact of competition on the business of Raychem or Tyco and the industries in
which they operate generally, industry growth and the absence of any adverse
material change in the financial condition and prospects of either Raychem or
Tyco or the industries in which they operate or in the financial markets in
general. Mathematical analysis, such as determining the average or median, is
not in itself a meaningful method of using peer group data.

Morgan Stanley compared the publicly available statistics for the Selected
Precedent Transactions listed above to the relevant financial statistics for the
merger based on the consideration to be received by the holders of Raychem's
common stock, based upon Tyco's closing common share price as of May 18, 1999.
The following table presents the median for the Selected Precedent Transactions
described above and the Raychem/Tyco merger of the following statistics:

    - the ratio for the acquired company of estimated aggregate value, defined
      as market capitalization plus total debt less cash and cash equivalent,
      to:

      1. last twelve months of revenue, and

      2. last twelve months EBITDA;

    - merger consideration to estimated next 12 months EPS; and

    - premium to unaffected stock price, defined, with respect to the merger,
      the Raychem stock price as of May 11, 1999, and with respect to the
      Selected Precedent Transactions, the stock price one month prior to
      commencement of the transactions.

The analysis of the Selected Precedent Transactions showed:

    - a median multiple for the acquired company of aggregate value to latest
      twelve months' revenue of 1.4 times,

    - a median multiple for the acquired company of 11.4 times last twelve
      months EBITDA,

    - a median multiple of merger consideration to next twelve months' earnings,
      based on estimates from securities research analysts, of 17.9 times, and

    - a median premium to unaffected price of 31.6%.

Based on the consideration to be received by the holders of Raychem's common
stock, assuming Tyco's closing common stock price as of May 18, 1999, these
statistics compared to:

    - a multiple of Raychem's aggregate value to latest twelve months' revenue
      of 1.8 times,

    - a multiple of Raychem's aggregate value to latest twelve months' EBITDA of
      11.4 times,

    - a multiple of Raychem's merger consideration to next twelve months'
      earnings, as estimated by Raychem's management, of 18.1 times, and

    - a premium of Raychem's unaffected price of 45.5%.

    No company utilized in the precedent transactions analysis as a comparison
is identical to Raychem. In evaluating the Selected Precedent Transactions,
Morgan Stanley made judgments and assumptions with regard to industry
performance, general business, economic, market and financial conditions and
other matters, many of which are beyond the control of Raychem and Tyco, such as
the impact of competition on the business of Raychem or Tyco and the industries
in which they operate generally, industry growth and the absence of any adverse
material change in the financial condition and prospects of Raychem or Tyco or
the industries in which they operate or in the financial markets in general.
Mathematical analysis, such as determining the average or median, is not in
itself a meaningful method of using precedent transactions data.

DISCOUNTED EQUITY VALUE

    Morgan Stanley performed an analysis of the present value per share of the
implied value of Raychem on a standalone basis based on Raychem's assumed future
trading price. Morgan Stanley observed that, based on a range of Raychem
earnings estimates for the calendar year 2001, illustrative multiples of
earnings ranging from 10.0 times to 18.0 times and an illustrative discount rate
of 14.0%, the present value of Raychem on a standalone basis ranged from $18.42
to $39.46 per share of Raychem common stock. This compared with an implied
assumed future trading price, assuming consummation of the merger pursuant to
the terms of the merger agreement, based on Tyco's earnings estimates of
securities research analysts for the calendar year 2001, illustrative multiples
of earnings estimates of 20.0 times to 30.0 times and an illustrative discount
rate of 13.0%, the present value of the combined entity on a share of Raychem
common stock equivalent basis ranged from $35.16 to $46.27. Morgan Stanley also
performed an analysis of the present value per share of the implied value of
Tyco on a standalone basis based on Tyco's future trading price. Morgan Stanley
observed that, based on a range of Tyco earnings estimates for the calendar year
2001, illustrative multiples of earnings ranging from 20.0 times to 30.0 times
and an illustrative discount rate of 13.0%, the present value of Tyco on a
standalone basis ranged from $79.65 to $132.74 per Tyco share.

                                       28
<PAGE>
DISCOUNTED CASH FLOW ANALYSIS

    Morgan Stanley performed a discounted cash flow analysis of Raychem to
determine a range of present values for Raychem based on the financial
projections prepared by the management of Raychem. Morgan Stanley calculated
unlevered free cash flow as the after-tax operating earnings of Raychem
excluding any interest income and interest expense plus depreciation and
amortization, plus deferred taxes, plus or minus net changes in non-cash working
capital, minus capital expenditures. Morgan Stanley calculated terminal values
by applying a range of multiples to EBITDA in fiscal year 2004 from 5.5 to 7.5
times. Morgan Stanley then discounted the unlevered free cash flows and terminal
values to present values using a discount rate of 11.5%. Based on this analysis
and the assumptions set forth, Morgan Stanley calculated per share equity value
estimates of Raychem ranging from approximately $24 to $31, excluding any
potential operational benefits to be realized from the merger. Morgan Stanley
noted that as of May 11, 1999, the price per share of Raychem common stock was
$25.44, which reflects an unaffected stock price and excludes the effect of
rumors regarding the merger in the market.

PRO FORMA MERGER ANALYSIS

    Morgan Stanley analyzed the pro forma impact of the merger on the combined
company's projected earnings per share for Tyco's fiscal year 2000. Such
analysis was based on earnings and synergies projections prepared by the
management of Raychem for Raychem and earnings projections for Tyco by
securities research analysts for Tyco. Morgan Stanley observed that the merger
would result in earnings per share accretion for Tyco in fiscal year 2000.

GENERAL

    The preparation of a fairness opinion is a complex process and is not
necessarily susceptible to partial analysis or summary description. In arriving
at its opinion, Morgan Stanley considered the results of all of its analyses as
a whole and did not attribute any particular weight to any analysis or factor
considered by it. Furthermore, Morgan Stanley believes that selecting any
portion of its analyses, without considering all analyses, would create an
incomplete view of the process underlying its opinion. In addition, Morgan
Stanley may have given various analyses and factors more or less weight than
other analyses and factors, and may have deemed various assumptions more or less
probable than other assumptions, so that the ranges of valuations resulting from
any particular analysis described above should not be taken to be Morgan
Stanley's view of the actual value of Raychem or Tyco. In performing its
analyses, Morgan Stanley made numerous assumptions with respect to industry
performance, general business and economic conditions and other matters, many of
which are beyond the control of Raychem or Tyco. Any estimates contained in
Morgan Stanley's analyses are not necessarily indicative of future results or
actual values, which may be significantly more or less favorable than those
suggested by such estimates.

    The analyses performed were prepared solely as part of Morgan Stanley's
analysis of the fairness of the consideration to be received by the holders of
Raychem common stock pursuant to the merger agreement from a financial point of
view to such holders and were conducted in connection with the delivery of the
Morgan Stanley opinion. The analyses do not purport to be appraisals or to
reflect the prices at which Raychem or Tyco might actually be sold. The
consideration to be received by the holders of Raychem common stock pursuant to
the merger agreement was determined through arm's-length negotiations between
Raychem and Tyco and was approved by the Raychem Board. Morgan Stanley provided
advice to Raychem during such negotiations; however, Morgan Stanley did not
recommend any specific consideration to Raychem or that any specific
consideration constituted the only appropriate consideration for the merger. In
addition, as described above, Morgan Stanley's

                                       29
<PAGE>
opinion and presentation to the Raychem Board was one of many factors taken into
consideration by Raychem's Board in making its decision to approve the merger.
Consequently, the Morgan Stanley analyses as described above should not be
viewed as determinative of the opinion of the Raychem Board with respect to the
consideration or of whether the Raychem Board would have been willing to agree
to a different consideration.

    The Raychem Board retained Morgan Stanley based upon Morgan Stanley's
qualifications, experience and expertise. Morgan Stanley is an internationally
recognized investment banking and advisory firm. Morgan Stanley, as part of its
investment banking business, is continuously engaged in the valuation of
businesses and securities in connection with mergers and acquisitions,
negotiated underwritings, competitive biddings, secondary distributions of
listed and unlisted securities, private placements and valuations for corporate,
estate and other purposes. In the past, Morgan Stanley and its affiliates have
provided financial advisory services for Raychem and Tyco and have received fees
for the rendering of these services. In the ordinary course of Morgan Stanley's
trading and brokerage activities, Morgan Stanley or any of its affiliates may at
any time hold long or short positions, may trade or otherwise effect
transactions, for its own account or for the account of customers in the equity
securities of Raychem or Tyco.

    Pursuant to the engagement letter, Morgan Stanley provided financial
advisory services and a financial fairness opinion in connection with the
merger, and Raychem agreed to pay Morgan Stanley a customary fee in connection
therewith. In addition, Raychem has also agreed to indemnify Morgan Stanley and
its affiliates, their respective directors, officers, agents and employees and
each person, if any, controlling Morgan Stanley or any of its affiliates against
certain liabilities and expenses, including certain liabilities under the
federal securities laws, arising out of Morgan Stanley's engagement.

REASONS OF TYCO FOR THE MERGER

    At a meeting of the Tyco Board held on May 12, 1999, the Tyco Board
determined that the merger with Raychem was in keeping with its corporate
strategy of complementing its internal growth with acquisitions that are likely
to benefit from cost reductions and synergies when combined with Tyco's existing
operations and that are expected to be accretive to earnings per share.

    In reaching its decision to approve the merger, Tyco's Board considered the
following material factors:

    - the expectation that Raychem's businesses could be readily integrated with
      Tyco's businesses, primarily its AMP, flow control and Polyken tape and
      adhesives businesses;

    - the expectation that the merger before restructuring and similar charges,
      and assuming the realization of certain of the cost savings referred to
      below and other synergies, would be immediately accretive to Tyco's
      earnings per share;

    - the belief of Tyco's management that there are prospects for reduction of
      Raychem corporate costs, possible elimination of facilities of the
      combined company and potential cost reductions for purchased materials and
      services;

    - the prospect of utilization of some of Raychem's business as a platform
      for further growth in the markets served by Raychem; and

    - Tyco's history of growth through acquisitions, including its substantial
      experience integrating acquired businesses with existing operations and
      thereby achieving synergies and cost savings.

INTERESTS OF CERTAIN PERSONS IN THE MERGER

GENERAL

    Certain Raychem executive officers and certain members of the Raychem Board
will receive benefits as a result of the merger that will be in addition to or
different from their interests as stockholders of Raychem generally. These
include, among other things, provisions in the merger agreement relating to
indemnification and the acceleration and/or payout of benefits under certain
agreements and employee benefit plans. The Raychem Board was aware of these
interests and considered them, among other matters, in approving the merger
agreement and the merger.

STOCK OWNERSHIP

    As of July 7, 1999, Raychem's directors and executive officers collectively
beneficially own 305,340 shares of Raychem common stock, not including options,
which are described below.

RAYCHEM EQUITY-BASED INCENTIVE AWARDS

    Pursuant to the terms of the merger agreement, at the time the merger is
completed, each outstanding option to purchase a share of Raychem common stock
issued to employees and directors of Raychem will be converted into an option to
acquire 0.4140 of a Tyco share. Shares of restricted stock of Raychem that have
vested prior to the merger or that will vest upon completion of the merger will
be treated the same in the merger as shares of unrestricted Raychem common
stock. Each unvested restricted share of Raychem common stock that does not vest
upon completion of the merger will be converted into 0.4140 of an unvested
restricted Tyco common share. In addition, Raychem's Key Employee Retention and
Severance Plan provides for:

    - all outstanding Raychem options and restricted stock held by participants
      in that plan that were scheduled to vest during the 12 month period
      commencing on the date of the merger to be immediately vested upon
      completion of the merger; and

    - full acceleration of vesting of unvested Raychem options and restricted
      stock upon termination of employment under certain qualifying
      circumstances within two years after the merger.

    Under Raychem's two non-employee director option plans, the non-employee
directors' options will become fully vested upon the the approval and adoption
of the merger agreement by the Raychem stockholders. The other terms and
conditions applicable immediately prior to the merger of each Raychem option and
each share of Raychem restricted stock will continue to apply after the merger.
The conversion of Raychem options into options to acquire Tyco shares pursuant
to the merger agreement is more fully described below in "Treatment of Raychem
Equity-Based Awards."

    As of July 7, 1999, directors and executive officers of Raychem owned an
aggregate of 89,250 shares of Raychem restricted stock and 2,508,307 Raychem
options, of which 89,250 shares of restricted stock and 1,418,725 options were
unvested. Approximately 7,600 shares of Raychem restricted stock and 598,976
Raychem options held by directors and executive officers will become vested as a
result of the merger.

<PAGE>
SEVERANCE BENEFITS UNDER THE KEY EMPLOYEE RETENTION AND SEVERANCE PLAN

    The Raychem Key Employee Retention and Severance Plan provides that, if an
executive officer's employment is actually or constructively terminated under
certain qualifying circumstances within two years following a change of control
of Raychem, the executive officer will be entitled to:

    - a pro-rated bonus for the year in which the termination of employment
      occurred, based on the executive officer's target bonus and the portion of
      the year worked;

    - a lump sum cash severance payment equal to 2.5 times the sum of the
      executive officer's base salary and target bonus;

    - full vesting of all outstanding unvested options and restricted stock; and

    - continued medical and dental benefits under Raychem's plans for the
      shorter of 2.5 years or until the executive officer obtains coverage under
      another employer's plans.

    Certain other severance benefits will be available to terminated officers
under Raychem's Executive Termination Compensation Policy.

RETENTION AND NON-COMPETITION AGREEMENT WITH RICHARD KASHNOW

    If the merger is completed, Dr. Kashnow will serve in the capacity of
Executive Vice President of Tyco International (US) Inc. pursuant to the terms
of a retention and non-competition agreement executed by Dr. Kashnow and Tyco at
the time of the execution of the merger agreement. The term of the agreement is
three years. Under the agreement, Dr. Kashnow will be entitled to receive an
annual salary of $900,000 and an annual incentive bonus determined on a basis
consistent with those of other similarly situated Tyco executives. Upon
completion of the merger, Tyco will grant Dr. Kashnow 90,000 shares of
restricted stock and 900,000 options which will vest pro rata over three years.
Vesting of the restricted stock will be subject to the satisfaction of certain
performance criteria. Dr. Kashnow will be entitled to receive other benefits
which are no less favorable than those provided to other Tyco executives.

    If Dr. Kashnow's employment terminates under certain qualifying
circumstances, including his resignation, he will receive certain severance
payments. In addition, Dr. Kashnow has agreed that during the two-year period
following his termination, he will not compete against the surviving corporation
in the merger and will not solicit employees of the surviving corporation, Tyco
or their subsidiaries.

INDEMNIFICATION

    The surviving corporation will provide to the individuals who have served as
officers or directors of Raychem, for six years after the merger,
indemnification as set forth by the certificate of incorporation and by-laws of
Raychem prior to the effective time of the merger. Tyco has also agreed to
provide, for at least six years after the merger, to the current directors and
officers of Raychem, an insurance and indemnification policy that is no less
favorable than the existing policy provided by Raychem with respect to acts
occurring prior to or at the effective time of the merger.

MATERIAL U.S. FEDERAL INCOME TAX AND BERMUDA TAX CONSEQUENCES

U.S. FEDERAL INCOME TAX CONSEQUENCES

    In the opinions of PricewaterhouseCoopers LLP and Shearman & Sterling, tax
advisors to Tyco and Raychem respectively, the following discussion is a summary
of the material U.S. federal income tax consequences of the exchange of Raychem
common stock for Tyco common shares and/or cash in the merger and the ownership
of Tyco common shares. The discussion which follows is based on the U.S.
Internal Revenue Code, Treasury Regulations promulgated thereunder,
administrative rulings and pronouncements and judicial decisions as of the date
hereof, all of which are subject to change, possibly with retroactive effect.

    The discussion below, except where specifically noted, does not address the
effects of any state, local or non-United States tax laws. In addition, the
discussion below relates to persons who hold Raychem common stock and will hold
Tyco common shares as capital assets. The tax treatment of a Raychem stockholder
may vary depending upon such stockholder's particular situation, and certain
stockholders may be subject to special rules not discussed below. Such
stockholders would include, for example, insurance companies, tax-exempt
organizations, financial institutions, broker-dealers, and individuals who
received Raychem common stock pursuant to the exercise of employee stock options
or otherwise as compensation. In addition, this discussion does not address the
tax consequences to any Raychem stockholder who will own 5% or more of either
the total voting power or the total value of the outstanding Tyco common shares
after the merger, determined after there is taken into account ownership under
the applicable attribution rules of the U.S. Internal Revenue Code, or non-U.S.
Holders, defined below, who have held more than 5% of the Raychem common stock
at any time within the five-year period ending at the consummation of the
merger.

    As used in this section, a "U.S. Holder" means a beneficial owner of Raychem
common stock who exchanges Raychem common stock for Tyco common shares and/or
cash and who is, for U.S. federal income tax purposes:

    - a citizen or resident of the U.S.;

    - a corporation, partnership or other entity, other than a trust, created or
      organized in or under the laws of the U.S. or any political subdivision
      thereof;

    - an estate whose income is subject to U.S. federal income tax regardless of
      its source; or

    - a trust

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

    (2) that has a valid election in effect under applicable U.S. treasury
       regulations to be treated as a U.S. person.

    As used in this section, a non-U.S. Holder is a holder of Raychem common
stock who exchanges Raychem common stock for Tyco common shares and/or cash and
who is not a U.S. Holder.

    1. CONSEQUENCES OF THE MERGER

    REORGANIZATION TREATMENT

    Consummation of the merger is conditioned upon the receipt of opinions of
PricewaterhouseCoopers LLP and Shearman & Sterling, which will be rendered as of
the time the merger becomes effective, that the merger will constitute a
reorganization for U.S. federal income tax purposes. The tax opinions will be
based on facts existing as of the consummation of the merger and

                                       33
<PAGE>
on certain representations as to factual matters made by Tyco, Tyco (PA) and
Raychem. Such representations, if incorrect in certain material respects, could
jeopardize the conclusions reached in the opinions. No ruling has been or will
be obtained from the U.S. Internal Revenue Service with respect to the merger.
The opinions of the tax advisors are not binding on the U.S. Internal Revenue
Service or the courts, and no assurance can be given that the U.S. Internal
Revenue Service would not be able to successfully challenge the conclusions
expressed in such opinions.

    For the merger to qualify as a reorganization for United States federal
income tax purposes, among other requirements, the Tyco common shares delivered
in the merger must represent a substantial portion of the overall consideration
received by Raychem stockholders. Based on the closing trading prices for Tyco
common shares on the day preceding the date the merger agreement was signed and
on the date hereof, the Tyco common shares represented by value 50% and
approximately 52%, respectively, of the total merger consideration. If the value
of the Tyco common shares at the date the merger becomes effective constitutes
less than 40% of the overall merger consideration, it may not be possible to
render the tax opinions. If a tax opinion cannot be delivered, Raychem may elect
to require Tyco to proceed with the acquisition of Raychem on a taxable basis.
Both PricewaterhouseCoopers LLP and Shearman & Sterling are of the opinion that,
based on facts existing as of June 30, 1999 and on representations made as of
that date by Tyco, Tyco (PA) and Raychem, and provided the value of the Tyco
common shares at the date the merger becomes effective constitutes a substantial
portion of the overall merger consideration received by Raychem stockholders,
the merger will qualify as a reorganization. Except as otherwise noted, the
remainder of the discussion assumes that the merger will qualify as a
reorganization.

    RECEIPT ONLY OF CASH

    In general, a Raychem stockholder who receives only cash in exchange for its
Raychem common stock in the merger will recognize capital gain or loss equal to
the difference between the amount of cash received and such stockholder's
adjusted tax basis in the shares of Raychem common stock surrendered, except to
the extent the stockholder actually or constructively owns Tyco common shares
and, as a result, the receipt of cash is treated as a distribution of a dividend
for U.S. federal income tax purposes. See generally below "--Receipt of Tyco
common shares and cash." Such gain or loss will be long-term capital gain or
loss if, as of the effective date of the merger, the holding period for such
shares is more than one year.

    RECEIPT ONLY OF TYCO COMMON SHARES

    A Raychem stockholder who receives only Tyco common shares in the merger
will not recognize any gain or loss upon such exchange, except to the extent
cash is received in lieu of a fractional Tyco common share, which will be taxed
as discussed below. The aggregate adjusted tax basis of Tyco common shares
received in such exchange, including any fractional interest in a Tyco common
share for which cash is received, will be equal to the aggregate adjusted tax
basis of the shares surrendered therefor. The holding period of the Tyco common
shares will include the holding period of the Raychem common stock surrendered
therefor.

    RECEIPT OF TYCO COMMON SHARES AND CASH

    A Raychem stockholder who receives a combination of cash and Tyco common
shares in the merger will recognize gain, if any, with respect to the shares so
exchanged but only to the extent of the lesser of (a) the amount of gain
realized with respect to the Raychem common stock and (b) the amount of cash
received, other than cash received in lieu of a fractional share, which is
discussed below. The amount of gain realized with respect to the exchanged
Raychem common stock will equal the excess, if any, of the cash, including cash
received in lieu of a fractional share, and the fair market value of the Tyco
common shares received over such stockholder's adjusted tax basis in the Raychem

                                       34
<PAGE>
common stock exchanged therefor. No loss will be recognized by a Raychem
stockholder who receives a combination of cash and Tyco common shares in the
merger, except in connection with cash received in lieu of a fractional share as
discussed below. The determination of gain, which is recognized, or loss, which
is not, is to be made on a share by share basis. That is, each Raychem share, or
block of shares acquired at the same price, will be treated as exchanged for a
pro rata portion of cash and Tyco common shares.

    Any gain recognized will be treated as capital gain unless, as discussed
below, the receipt of the cash has the effect of the distribution of a dividend
for U.S. federal income tax purposes, in which case such gain will be treated as
ordinary dividend income to the extent of the stockholder's ratable share of
Raychem's accumulated earnings and profits. Any capital gain will be long-term
capital gain if, as of the date of the exchange, the holding period for such
shares is more than one year.

    The adjusted tax basis of the Tyco common shares received in such exchange,
including any fractional interest in a Tyco common share for which cash is
received, generally will be equal to the tax basis of the shares surrendered
therefor, decreased by the amount of cash received and increased by the amount
of gain or dividend income recognized, if any. The holding period of the Tyco
common shares received will include the holding period of the Raychem common
stock exchanged therefor. As a result of these "substitute" basis rules, in
general, any inherent gain or loss with respect to Raychem common stock that is
not recognized in the exchange will be reflected as the difference between the
basis and the value of the Tyco common shares received therefor, after making
the basis adjustments described above.

    In determining whether gain recognized with respect to cash received by a
Raychem stockholder pursuant to the merger will be treated as a dividend, a
Raychem stockholder will be treated as if the portion of the Raychem common
stock exchanged for cash in the merger had been instead exchanged for Tyco
common shares, followed immediately by a redemption of such hypothetical shares
by Tyco for cash, referred to in this document as the "hypothetical redemption."
A Raychem stockholder will recognize capital gain rather than dividend income
with respect to the cash received if the hypothetical redemption is "not
essentially equivalent to a dividend" or is "substantially disproportionate"
with respect to such stockholder, taking into account in each case the
stockholder's actual and constructive ownership of Tyco common shares.

    The hypothetical redemption would be "not essentially equivalent to a
dividend" with respect to a Raychem stockholder if, based on all the facts and
circumstances, it results in a "meaningful reduction" in such stockholder's
percentage ownership of Tyco common shares. The U.S. Internal Revenue Service
has indicated in a published ruling that a shareholder in a publicly-held
corporation whose relative stock interest in the corporation is minimal and who
exercises no control over corporate affairs is generally treated as having had a
meaningful reduction in his or her stock after a redemption transaction if his
or her percentage stock ownership in the corporation has been reduced to any
extent, taking into account the shareholder's actual and constructive ownership
before and after the hypothetical redemption. In that ruling, a reduction from
 .0001118% to .0001081% was held to be a meaningful reduction.

    The hypothetical redemption transaction would be "substantially
disproportionate," and therefore would not have the effect of a distribution of
a dividend, with respect to a Raychem stockholder, if the percentage of Tyco
common shares actually and constructively owned by such stockholder immediately
after the hypothetical redemption is less than 80% of the percentage of Tyco
common shares actually, hypothetically and constructively owned by such
stockholder immediately after both the actual and deemed receipt of the Tyco
common shares but before the hypothetical redemption.

    Raychem stockholders should consult their tax advisors as to the possibility
that all or a portion of any cash received in exchange for their Raychem common
stock will be treated as a dividend and with respect to the consequences
thereof, including the eligibility of Raychem stockholders that are

                                       35
<PAGE>
corporations for a dividends-received-deduction and treatment of the dividend as
an "extraordinary dividend" under section 1059 of the U.S. Internal Revenue
Code.

    CASH RECEIVED IN LIEU OF A FRACTIONAL TYCO COMMON SHARE

    A Raychem stockholder who receives cash in lieu of a fractional Tyco common
share will be treated as having received such fractional share pursuant to the
merger and then as having exchanged such fractional share for cash in a
redemption by Tyco. Such a deemed redemption will be treated as a sale of the
fractional share, provided that it either is "not essentially equivalent to a
dividend" or is "substantially disproportionate" with respect to the Raychem
stockholder, as discussed in the preceding section. If the deemed redemption is
treated as a sale of a fractional share, a Raychem stockholder will recognize
gain or loss equal to the difference between the amount of cash received and the
portion of the basis of the Tyco common shares allocable to such fractional
share interest. Such gain or loss will be long-term capital gain or loss if, as
of the date of the exchange, the holding period for such shares is more than one
year.

    TAXABLE ACQUISITION

    If, as discussed above, one or both tax opinions is not rendered and Raychem
elects to require Tyco to proceed with the acquisition of Raychem on a taxable
basis, Raychem stockholders will recognize capital gain or loss equal to the
difference between the amount of cash and the fair market value of the Tyco
common shares received and their adjusted tax bases in the Raychem common stock
exchanged. The gain or loss will be long-term capital gain or loss if, as of the
effective date of the merger, the holding period for such shares is more than
one year. The basis of the Tyco common shares received will be equal to their
fair market value at the effective time and the holding period of such shares
will begin on the day following the time the merger becomes effective.

    NON-U.S. HOLDERS

    Non-U.S. Holders who receive cash in the merger will not be subject to U.S.
federal income or withholding tax except as set forth in paragraph 3.b below,
applied with respect to Raychem common stock, or unless the receipt of the cash
is taxable as a dividend, as discussed above, in which case such amount may be
subject to withholding at a 30% rate, or at such lower rate set forth in an
applicable treaty.

    CONSEQUENCES TO RAYCHEM, TYCO AND TYCO (PA)

    No income, gain or loss will be recognized by Raychem, Tyco or Tyco (PA),
whether the merger is consummated as a reorganization or whether Raychem elects,
pursuant to the merger agreement, to require Tyco to proceed with the
acquisition of Raychem on a taxable basis.

    2. TRANSFER TAXES

    In the event that any state or local transfer taxes are imposed on Raychem
stockholders as a result of the merger, Raychem will pay all such transfer
taxes, if any, directly to state and local taxing authorities on behalf of all
Raychem stockholders. Any such payments by Raychem made on behalf of the Raychem
stockholders may result in dividend income to each Raychem stockholder on behalf
of whom such payment is made. The amount of such dividend income attributable to
each share of Raychem common stock cannot be determined at this time, but is not
expected to be material.

                                       36
<PAGE>
    3. OWNERSHIP OF TYCO COMMON SHARES

    a. U.S. Holders

    DISTRIBUTIONS

    Distributions made to U.S. Holders of Tyco common shares will be treated as
dividends and are taxable as ordinary income to the extent that such
distributions are made out of Tyco's current or accumulated earnings and profits
as determined for U.S. federal income tax purposes, with any excess being
treated as a tax-free return of capital which reduces such U.S. Holder's tax
basis in the Tyco common shares to the extent thereof, and thereafter as capital
gain from the sale or exchange of property. The U.S. federal income tax
treatment described in the immediately preceding sentence applies whether or not
such distributions are treated as a return of capital for non-tax purposes.
Amounts taxable as dividends generally will be treated as foreign source
"passive" or "financial services" income for foreign tax credit purposes. The
amount of any distribution of property other than cash will be the fair market
value of such property on the date of distribution by Tyco. U.S. Holders of Tyco
common shares that are corporations generally will not be entitled to claim a
dividends received deduction with respect to distributions by Tyco because Tyco
is a foreign corporation.

    DISPOSITION

    Gain or loss recognized by a U.S. Holder of Tyco common shares on the sale,
exchange or other taxable disposition of Tyco common shares will be subject to
U.S. federal income taxation as capital gain or loss in an amount equal to the
difference between the amount realized on such sale, exchange or other
disposition and such U.S. Holder's adjusted tax basis in the Tyco common shares
surrendered. Such gain or loss will be long term capital gain or loss if such
U.S. Holder's holding period for its Tyco common shares is more than one year.
Any gain or loss so recognized generally will be United States source.

    b. Non-U.S. Holders

    DISTRIBUTIONS AND DISPOSITION

    In general, and subject to the discussion below under "Information Reporting
and Backup Withholding," a non-U.S. Holder will not be subject to U.S. federal
income or withholding tax on income from distributions with respect to, or gain
upon the disposition of, Tyco common shares, unless either (1) the income or
gain is effectively connected with the conduct by the non-U.S. Holder of a trade
or business in the U.S. or (2) in the case of gain realized by an individual
non-U.S. Holder upon a disposition of Tyco common shares, the non-U.S. Holder is
present in the U.S. for 183 days or more in the taxable year of the sale and
certain other conditions are met.

    In the event that clause 1 in the preceding paragraph applies, such income
or gain generally will be subject to regular U.S. federal income tax in the same
manner as if such income or gain, as the case may be, were realized by a U.S.
Holder. In addition, if such non-U.S. Holder is a non-U.S. corporation, such
income or gain may be subject to a branch profits tax at a rate of 30%, although
a lower rate may be provided by an applicable income tax treaty. In the event
that clause 2, but not clause 1, in the preceding paragraph applies, the gain
generally will be subject to tax at a rate of 30%, or such lower rate as may be
provided by an applicable income tax treaty.

    4. INFORMATION REPORTING AND BACKUP WITHHOLDING

    Certain U.S. Holders may be subject to information reporting with respect to
the receipt of cash in the merger and with respect to payments of dividends on,
and the proceeds of the disposition of, Tyco common shares. U.S. Holders who are
subject to information reporting and who do not provide appropriate information
when requested may be subject to backup withholding at a 31% rate. U.S.

                                       37
<PAGE>
Holders should consult their tax advisors regarding the imposition of backup
withholding and information reporting with respect to the receipt of cash in the
merger and with respect to distributions on, and dispositions of, Tyco common
shares.

    If the Raychem common stock is held by a non-U.S. Holder through a non-U.S.,
and non-U.S. related, broker or financial institution, information reporting and
backup withholding generally would not be required with respect to the receipt
of cash in the merger. If the Tyco common shares are held by a non-U.S. Holder
through a non-U.S., and non-U.S. related, broker or financial institution,
information reporting and backup withholding generally would not be required
with respect to distributions on and dispositions of Tyco common shares.
Information reporting, and possibly backup withholding, may apply if the Raychem
common stock or Tyco common shares are held by a non-U.S. Holder through a U.S.,
or U.S. related, broker or financial institution and the non-U.S. Holder fails
to provide appropriate information. Non-U.S. Holders should consult their tax
advisors regarding the imposition of backup withholding and information
reporting with respect to the receipt of cash in the merger and with respect to
distributions on and dispositions of Tyco common shares.

BERMUDA TAX CONSEQUENCES

    In the opinion of Appleby, Spurling & Kempe, attorneys in Bermuda for Tyco,
there will be no Bermuda income, corporation or profits tax, withholding tax,
capital gains tax, capital transfer tax, estate duty or inheritance tax payable
in respect of the delivery of Tyco common shares and/or cash to Raychem
stockholders in exchange for Raychem common stock pursuant to the merger. In
addition, as of the date hereof, there is no Bermuda income, corporation or
profits tax, withholding tax, capital gains tax, capital transfer tax, estate
duty or inheritance tax payable in respect of capital gains realized on a
disposition of Tyco common shares or in respect of distributions by Tyco with
respect to Tyco common shares. Furthermore, Tyco has received from the Minister
of Finance of Bermuda under the Exempted Undertakings Tax Protection Act of 1966
an undertaking that, in the event of there being enacted in Bermuda any
legislation imposing any tax computed on profits or income, including any
dividend or capital gains withholding tax, or computed on any capital assets,
gain or appreciation or any tax in the nature of an estate or inheritance tax or
duty, the imposition of such tax shall not be applicable to Tyco or any of its
operations, its common shares or its obligations, until the year 2016. This
undertaking applies to Tyco common shares. It does not, however, prevent the
application of Bermuda taxes to persons ordinarily resident in Bermuda.

    THE FOREGOING DISCUSSION IS INTENDED ONLY AS A SUMMARY AND DOES NOT PURPORT
TO BE A COMPLETE ANALYSIS OR LISTING OF ALL POTENTIAL TAX EFFECTS RELEVANT TO A
DECISION WHETHER TO VOTE IN FAVOR OF APPROVAL AND ADOPTION OF THE MERGER
AGREEMENT. RAYCHEM STOCKHOLDERS ARE URGED TO CONSULT THEIR TAX ADVISORS
CONCERNING THE UNITED STATES FEDERAL, STATE, LOCAL AND NON-UNITED STATES TAX
CONSEQUENCES OF THE MERGER TO THEM.

ACCOUNTING TREATMENT

    The merger will be treated as a purchase for accounting and financial
reporting purposes. Under this method of accounting, the assets and liabilities
of Raychem will be recorded on Tyco's books at their estimated fair market value
with the remaining purchase price reflected as goodwill. For more information,
see the notes to the Unaudited Pro Forma Combined Condensed Financial
Information beginning on page 62.

                                       38
<PAGE>
CERTAIN LEGAL MATTERS

    Tyco, Tyco (PA) and Raychem have committed to use their reasonable best
efforts to take whatever actions are required to obtain necessary regulatory
approvals.

    The Hart-Scott-Rodino Antitrust Improvements Act of 1976 prohibits Tyco,
Tyco (PA) and Raychem from completing the merger until certain information and
materials have been furnished to the U.S. Federal Trade Commission and the
Antitrust Division of the U.S. Department of Justice and a required waiting
period has expired or been terminated. Tyco and Raychem have filed their
Premerger Notification and Report Forms pursuant to the HSR Act with the FTC and
the Antitrust Division and the applicable waiting period began on June 24, 1999.
Tyco and Raychem expect that the applicable waiting period will expire on July
24, 1999, although the waiting period could be extended if the FTC or the
Antitrust Division requests additional information. Even after the waiting
period expires or is terminated, the FTC or the Antitrust Division could take
such action under the antitrust laws as it deems necessary or desirable in the
public interest, including seeking divestiture of substantial assets of Tyco or
Raychem.

    The merger is also subject to notification to, and approval by, the
Commission of the European Communities under Council Regulation (EEC) No.
4064/89 of 21 December 1989 on the control of concentrations. Tyco and Raychem
made the requisite filing with the EC Commission on June 23, 1999. They expect
the EC Commission to make a determination regarding approval of the merger on or
about July 26, 1999. Neither Tyco, Tyco (PA) nor Raychem believes that
consummation of the merger will result in a violation of any applicable
antitrust laws. However, there can be no assurance that a challenge to the
merger on antitrust grounds will not be made or, if such a challenge is made, of
the result.

    Tyco, Tyco (PA) and Raychem do not believe that any additional material
governmental filings in the United States or the European Economic Area, other
than the Articles of Merger in Nevada and Certificate of Merger in Delaware, are
required with respect to the merger. In addition to the United States and the
European Economic Area, Tyco and Raychem conduct operations in a number of
countries in which regulatory filings or approvals may be required in connection
with the consummation of the merger. Tyco and Raychem believe that all such
material filings and approvals have been made or obtained, or will be made or
obtained, as the case may be.

U.S. FEDERAL SECURITIES LAW CONSEQUENCES

    Recipients of Tyco common shares issued in connection with the merger can
freely transfer such shares under the U.S. Securities Act of 1933, except that
persons who are deemed to be "affiliates", as such term is defined under the
Securities Act, of Raychem prior to the merger may only sell shares they receive
in the merger in transactions permitted by the resale provisions of Rule 145
under the Securities Act, or as otherwise permitted under the Securities Act.
Individuals or entities that control, are controlled by, or are under common
control with, Raychem, including directors and certain officers of Raychem, are
typically considered to be affiliates.

    In general, under Rule 145, for one year following the consummation of the
merger, Raychem affiliates will be subject to the following restrictions on the
public sale of Tyco common shares acquired in the merger:

    - a Raychem affiliate, together with certain related persons, may sell only
      through unsolicited "broker transactions" or in transactions directly with
      a "market maker," as such terms are defined in Rule 144 under the
      Securities Act,

    - the number of shares a Raychem affiliate may sell, together with certain
      related persons and certain persons acting in concert, within any
      three-month period for purposes of Rule 145 may

                                       39
<PAGE>
      not exceed the greater of 1% of the outstanding Tyco common shares or the
      average weekly trading volume of such stock during the four calendar weeks
      preceding such sale, and

    - a Raychem affiliate may sell only if Tyco remains current with its
      informational filings with the SEC under the Exchange Act.

    After the end of one year from the consummation of the merger, a Raychem
affiliate may sell Tyco common shares received in the merger without such manner
of sale or volume limitations, provided that Tyco is current with its Exchange
Act informational filings and such Raychem affiliate is not then an affiliate of
Tyco. Two years after the consummation of the merger, an affiliate of Raychem
may sell such Tyco common shares without any restrictions so long as such
affiliate had not been an affiliate of Tyco for at least three months prior to
such sale.

DIVIDENDS

    Although the payment of dividends by Tyco in the future will depend on
business conditions, Tyco's financial condition and earnings and other factors,
Tyco expects to declare regularly scheduled dividends consistent with the
practices of Tyco prior to the merger. The merger agreement restricts each of
Raychem and Tyco from declaring, setting aside, making or paying any dividend or
other distribution in respect of its capital stock, other than its regularly
scheduled dividend consistent with past practices, during the period from the
date of the merger agreement until the earlier of the termination of the merger
agreement or the consummation of the merger.

STOCK EXCHANGE LISTING

    It is a condition to the merger that the NYSE authorize for listing the Tyco
common shares to be delivered in connection with the merger. In addition, Tyco
expects to list such shares on the London Stock Exchange and the Bermuda Stock
Exchange in due course after the completion of the merger.

APPRAISAL RIGHTS

    If the merger is consummated, a holder of record of shares of Raychem common
stock who objects to the terms of the merger may seek an appraisal under
Delaware law of the fair value of such holder's shares. The following is a
summary of the material provisions of Delaware law. This discussion is qualified
in its entirety by reference to Section 262 of the Delaware General Corporation
Law. A copy of this provision is attached to this document as Annex C. If you
fail to take any action required by Delaware law, your rights to an appraisal
will be waived or terminated.

ELECTING APPRAISAL RIGHTS

    To exercise appraisal rights, the record holder of Raychem common stock
must:

    - deliver a written demand for appraisal to Raychem before the Raychem
      stockholders vote on the merger agreement, and

    - not vote to approve the merger.

    A stockholder demanding appraisal rights must do so by a separate written
demand. This demand must reasonably inform Raychem of the identity of the holder
of record and that the stockholder demands appraisal of his or her shares of
Raychem common stock. A VOTE AGAINST THE MERGER, IN PERSON OR BY PROXY, DOES NOT
CONSTITUTE A DEMAND.

    If you deliver a proxy that has been left blank, the proxy will be voted FOR
the approval of the merger, unless the proxy is revoked before the vote is
taken. Therefore, if you intend to exercise your appraisal rights and you vote
by proxy, you must not leave the proxy blank. You should either vote AGAINST the
merger or ABSTAIN from voting for or against the approval of the merger.

    A demand for appraisal must be delivered to the Corporate Secretary, Raychem
Corporation, MS 120-1A, 300 Constitution Drive, Menlo Park, California 94025.

RECORD HOLDERS MUST DEMAND APPRAISAL RIGHTS

    Only the record holder of the Raychem common stock is entitled to demand
appraisal rights. The demand must be executed by or for the record holder, fully
and correctly, as the holder's name appears on the holder's stock certificates.

    - If the Raychem common stock is owned of record in a fiduciary capacity,
      such as by a trustee, guardian or custodian, the demand should be executed
      in that capacity.

    - If the Raychem common stock is owned of record by more than one person, as
      in a joint tenancy or tenancy in common, the demand should be executed by
      or for all owners.

    - An authorized agent, including one of two or more joint owners, may
      execute the demand for appraisal for a holder of record. The agent must
      identify the owner or owners of record and expressly disclose the fact
      that, in executing the demand, the agent is acting as agent for the owner
      or owners of record.

    - A holder of record, such as a broker, who holds common stock as nominee
      for beneficial owners, may exercise a holder's right of appraisal with
      respect to common stock held for all or less than all of such beneficial
      owners. In that case, the written demand should set forth the number of
      shares of common stock covered by the demand. If no number of shares of
      common stock is expressly mentioned, the demand will be presumed to cover
      all shares of common stock standing in the name of the record holder.

NOTIFICATION OF MERGER'S EFFECTIVENESS

    Within ten days after the effective time of the merger, the surviving
corporation in the merger will send notice of the effectiveness of the merger to
each person who has satisfied the foregoing conditions.

COURT PETITION MUST BE FILED

    Within 120 days after the effective time of the merger, the surviving
corporation in the merger or any stockholder who has satisfied the foregoing
conditions may file a petition in the Delaware Court of Chancery demanding a
determination of the fair value of the Raychem common stock. Tyco (PA) does not
intend to file a petition with the court. Stockholders seeking to exercise
appraisal rights should initiate all necessary action to perfect their appraisal
rights within the time periods prescribed by Delaware law.

STATEMENT REGARDING SHARES NOT VOTED FOR MERGER

    Within 120 days after the effective time of the merger, any stockholder who
has complied with the requirements for exercise of appraisal rights is entitled,
upon written request, to receive a statement setting forth the aggregate number
of shares of common stock not voted in favor of the merger and with respect to
which demands for appraisal have been made and the aggregate number of holders
of such stock. The surviving corporation in the merger is required to mail this
statement within ten days after it receives the written request.

APPRAISAL PROCEEDING BY DELAWARE COURT

    If a petition for an appraisal is timely filed, after a hearing on the
petition, the Delaware Court of Chancery will determine which of the
stockholders are entitled to appraisal rights. The court will

                                       41
<PAGE>
appraise the common stock owned by the stockholders and determine its fair
value. In determining fair value, the court may consider a number of factors,
including market values of Raychem's stock, asset values and other generally
accepted valuation considerations, but will exclude any element of value arising
from the accomplishment and expectation of the merger. The court will also
determine the amount of interest, if any, to be paid upon the value of the
common stock to the stockholders entitled to appraisal.

    The value determined by the court for Raychem common stock could be more
than, less than, or the same as the merger consideration. The court may also
order that all or a portion of any stockholder's expenses incurred in connection
with an appraisal proceeding, including reasonable attorneys' fees and fees and
expenses of experts utilized in the appraisal proceeding, be charged against the
value of all common stock entitled to appraisal.

EFFECT OF APPRAISAL DEMAND ON VOTING AND RIGHT TO DIVIDENDS

    Any stockholder who has duly demanded an appraisal in compliance with
Delaware law will not, after the effective time of the merger, be entitled to
vote the shares subject to the demand for any purpose. The shares subject to the
demand will not be entitled to dividends or other distributions, other than
those payable or deemed to be payable to stockholders of record as of a date
prior to the effective time.

LOSS, WAIVER OR WITHDRAWAL OF APPRAISAL RIGHTS

    Holders of Raychem common stock lose the right to appraisal if no petition
for appraisal is filed within 120 days after the effective time of the merger. A
stockholder will also lose the right to an appraisal by delivering to the
surviving corporation a written withdrawal of such stockholder's demand for an
appraisal. In addition, any attempt to withdraw that is made more than 60 days
after the effective time requires the written approval of the surviving
corporation. If appraisal rights are not perfected or a demand for appraisal
rights is withdrawn, a stockholder will be entitled to receive the consideration
otherwise payable pursuant to the merger. Whether such stockholder receives Tyco
shares, cash or a combination of shares and cash will be determined at such time
by Tyco (PA) in its discretion. The value of any Tyco shares paid to such
stockholder will be based on the same average price for Tyco shares used to
determine the allocation of the merger consideration among the other Raychem
stockholders, regardless of the market price of Tyco shares at the time the
stockholder receives the merger consideration. An election form of a stockholder
that seeks appraisal rights will have no force and effect.

DISMISSAL OF APPRAISAL PROCEEDING

    If an appraisal proceeding is timely instituted, such proceeding may not be
dismissed as to any stockholder who has perfected a right of appraisal without
the approval of the court.

                              THE MERGER AGREEMENT

GENERAL

    This section describes the material provisions of the merger agreement. This
description is not complete, and stockholders are encouraged to read the full
text of the merger agreement, which is annexed to this document. In addition,
important information about the merger agreement and the merger is provided in
the previous section entitled "The Merger" beginning on page 18.

EFFECTIVE TIME

    Promptly after the satisfaction or waiver of the conditions to the merger
set forth in the merger agreement:

    1.  Tyco (PA) will file Articles of Merger with the Secretary of State of
       the State of Nevada, as prescribed by Nevada Law; and

    2.  Raychem will file a Certificate of Merger with the Secretary of State of
       the State of Delaware, as prescribed by Delaware law.

    The effect of these filings is that Raychem will merge with and into Tyco
(PA). Tyco (PA) is a wholly owned subsidiary of Tyco.

MERGER CONSIDERATION

GENERAL

    In the merger, Raychem's stockholders will receive, in the aggregate, merger
consideration consisting of:

    1.  cash equal to $18.50 multiplied by the number of shares of Raychem
       common stock outstanding at the effective time of the merger; and

    2.  Tyco common shares equal to 0.2070 multiplied by the number of shares of
       Raychem common stock outstanding at the effective time of the merger.

Based on the number of shares of Raychem common stock outstanding as of July 7,
1999, approximately $1.44 billion and 16.1 million Tyco shares will be delivered
to Raychem's stockholders in the aggregate. The cash and Tyco shares will be
apportioned so that Raychem stockholders will receive for each of their shares
of Raychem common stock, merger consideration having a value, sometimes referred
to in this document as the "per share value of the merger consideration," of
$18.50 plus the value of 0.2070 of a Tyco share. The value of a Tyco common
share for these purposes will be the average of the volume weighted average sale
prices per Tyco common share on the New York Stock Exchange for the three
consecutive trading days beginning on the date the merger becomes effective.

    A Raychem stockholder will not receive a fraction of a Tyco common share in
the merger. All Tyco common shares that a Raychem stockholder is entitled to
receive will be aggregated. Any fractional Tyco common share resulting from the
aggregation will be paid in cash equal to the fraction multiplied by the value
of a Tyco common share described above.

MAKING THE ELECTION

    EXCHANGE AGENT.  Tyco (PA) has selected ChaseMellon Shareholder Services,
LLC, which is the transfer agent for Tyco, to serve as the exchange agent for
purposes of effecting the election and proration procedures.

                                       43
<PAGE>
    ELECTION FORM.  An election form, which is also a transmittal letter, is
included with this document. The election form must be used to make the election
to receive cash, Tyco shares or a combination of cash and Tyco shares as merger
consideration. To make an election, Raychem stockholders should:

    1.  submit a properly completed and signed election form accompanied by the
       certificates representing the shares of Raychem stock as to which the
       election is being made; or

    2.  in the case of Raychem stockholders whose shares are held in book-entry
       form, instruct the broker, dealer, bank or other financial institution
       that holds the shares to make an election on their behalf by:

       - transferring their shares of Raychem common stock to an account
         established by ChaseMellon for this purpose at the Depository Trust
         Company, and

       - transmitting a message through DTC to ChaseMellon setting forth the
         election and otherwise agreeing to be bound by the terms of the
         election form.

    Stockholders of record that want to make an election, but are unable to
furnish the exchange agent with their stock certificates prior to the election
deadline referred to below, should use the guaranteed delivery procedures set
forth in the election form. Delivery of the certificates must be guaranteed in
the election form by an Eligible Guarantor Institution, generally a bank,
broker, dealer and certain other financial institutions. In addition, the
election form must be submitted to the exchange agent before the election
deadline, and the certificates representing shares of Raychem common stock must
be delivered to the exchange agent within three business days of submitting the
election form.

    The election form is also a transmittal letter, so that stockholders who
have delivered an election form with their shares of Raychem common stock to the
exchange agent will not have to take any further action after the merger to
receive their merger consideration.

    If a Raychem stockholder delivers his election form to the exchange agent
after the election deadline or the election form does not comply with the
required procedures, the stockholder will not be regarded as having made an
election. See "Non-Electing Shares" below. Raychem stockholders should read the
election form for a more complete discussion of the election procedures.

    ELECTION DEADLINE.  The deadline for Raychem stockholders to make their
elections is the close of business on the last business day before the date that
the merger is effected. Tyco and Raychem expect the merger to be consummated on
the day that the Raychem stockholders vote to approve the merger. Accordingly,
Raychem stockholders who wish to make an election should make sure that their
election is received by the exchange agent no later than 5 p.m. Eastern Time on
August 11, 1999.

    If the merger is not consummated by August 19, 1999, Tyco and Raychem will
issue a press release on the Dow Jones News Service at least five business days
before consummating the merger. The press release will inform stockholders of
the last date for submitting and/or changing their election forms.

    CHANGES AND REVOCATION.  Any stockholder may change his election prior to
the election deadline:

    - by submitting to the exchange agent a properly completed and signed
      revised election form; or

    - in the case of stockholders whose shares are held in book-entry form, by
      causing a new message with revised election information to be transmitted
      through DTC to the exchange agent.

    Any holder of Raychem common stock may revoke its election at any time prior
to the election deadline:

    - by written notice to the exchange agent; or

                                       44
<PAGE>
    - in the case of stockholders whose shares are held in book-entry form, by
      causing a new message to be transmitted through DTC to the exchange agent
      withdrawing the shares previously deposited and specifying the name and
      number of the account at DTC to be credited.

    As soon as practicable after the election deadline, the exchange agent will
determine the number of cash electing shares, stock electing shares and
non-electing shares, and will notify the surviving corporation of its
determination. Promptly after such notification, Tyco and the surviving
corporation will issue a press release announcing the allocation of the merger
consideration.

    GENERAL.  Raychem stockholders having a preference as to the form of
consideration they wish to receive for their shares of Raychem common stock
should make an election. None of Tyco, Tyco (PA), Raychem or the Raychem Board
makes any recommendation as to whether stockholders should make an election or
what election they should make. Each holder of Raychem common stock must make
his or her own decision whether to make an election and, if so, what election to
make.

    The allocation of the merger consideration among the Raychem stockholders
depends upon the elections made by the stockholders and the average of the
volume weighted average sale prices of Tyco common shares referred to above. The
election forms may be submitted until the day before the merger is effective,
and it may take a period of time before the exchange agent can verify the
election forms and tabulate the election results. The average share price cannot
be determined until the close of trading on the third trading day beginning on
the date the merger is consummated. Therefore, there will be a period of time
following the consummation of the merger before the allocation of the merger
consideration can be determined. Consequently, the payment of the merger
consideration to Raychem stockholders will begin some time after the merger is
consummated.

THE PRORATION RULES

    These are the proration rules that will govern the allocation of the cash
and stock consideration in the merger.

    CASE 1: MORE CASH CONSIDERATION IS ELECTED THAN THE AMOUNT OF CASH AVAILABLE
     FOR PAYMENT

    In this case, Tyco will calculate a proration factor for the shares of
Raychem common stock making a cash election. This proration factor will equal
(1) the total amount of cash available for payment divided by (2) the total cash
that would have to be paid if all cash elections were honored in full. This
latter amount is determined by multiplying the number of shares of Raychem
common stock electing cash by the per share value of the merger consideration.

    - Each share of Raychem common stock electing Tyco common shares will be
      exchanged for a fraction of a Tyco common share having a value equal to
      the per share value of the merger consideration;

    - Each share of Raychem common stock as to which no election has been made
      will be exchanged for a fraction of a Tyco common share having a value
      equal to the per share value of the merger consideration; and

    - Each share of Raychem common stock electing cash will be exchanged for:

     1.  cash equal to the per share value of the merger consideration
        multiplied by the proration factor; and

                                       45
<PAGE>
     2.  a fraction of a Tyco common share having a value equal to the per share
        value of the merger consideration less the amount of the cash.

<TABLE>
<S>        <C>        <C>
           EXAMPLE:   In this and the examples that follow, assume:

                      (a) there are 80,000,000 shares of Raychem common stock outstanding at
                      the time of the merger. The total amount of cash that would be paid in
                      the merger, assuming there are no dissenting shares, is:

                        $18.50 X 80,000,000 = $1,480,000,000,

                      and the total number of shares that would be delivered is:

                      0.2070 X 80,000,000 = 16,560,000 shares;

                      (b) the average of the volume weighted average sale prices of a Tyco
                      common share for the three days beginning on the date the merger becomes
                      effective is $89.375, so that the per share value of the merger
                      consideration is $37.00 and the fraction of a Tyco common share having a
                      value equal to the per share value of the merger consideration is:

                      $37.00  DIVIDED BY $89.375 = 0.4140.

                      Assume for this example that cash is elected with respect to 60% of the
                      shares of Raychem common stock. The cash proration factor will be:

                      $1,480,000,000  DIVIDED BY (48,000,000 X $37.00) = 0.8333.

                      Each share of Raychem common stock as to which an election has been made
                      to receive Tyco common shares or as to which no election has been made
                      will receive 0.4140 of a Tyco common share. Each share of Raychem common
                      stock as to which a cash election has been made will receive:

                          - cash in the amount of 0.8333 X $37.00 = $30.83, and

                          - a fraction of a Tyco common share having a value equal to the
                          balance of the per share value of the merger consideration, or
                            ($37.00 - $30.83)  DIVIDED BY $89.375 = 0.0690 of a Tyco common
                            share.
</TABLE>

    CASE 2: MORE STOCK CONSIDERATION IS ELECTED THAN THE NUMBER OF TYCO COMMON
    SHARES AVAILABLE FOR DELIVERY

    In this case, Tyco will calculate a proration factor for the shares of
Raychem common stock making a stock election. This proration factor will equal
(1) the total number of Tyco common shares available for payment, divided by (2)
the total number of Tyco common shares that would have to be delivered if all
stock elections were honored in full. This latter number is determined by
multiplying the number of shares of Raychem common stock electing stock by the
fraction of a Tyco common share having a value at the time of the merger equal
to the per share value of the merger consideration.

    - Each share of Raychem common stock electing cash will be exchanged for
      cash in the amount of the per share value of the merger consideration;

    - Each share of Raychem common stock as to which no election has been made
      will be exchanged for cash in the amount of the per share value of the
      merger consideration; and

    - Each share of Raychem common stock electing Tyco common shares will be
      exchanged for:

     1.  a fraction of a Tyco common share having a value equal to the per share
        value of the merger consideration multiplied by the proration factor;
        and

                                       46
<PAGE>
     2.  cash equal to the per share value of the merger consideration less the
        value of the fraction of a Tyco common share referred to in clause 1.

<TABLE>
<S>        <C>        <C>
           EXAMPLE:   Assume for this example that stock is elected with respect to 60% of the
                      shares of Raychem common stock. The stock proration factor will be:

                        16,560,000  DIVIDED BY (48,000,000 X 0.4140) = 0.8333.

                      Each share of Raychem common stock as to which an election has been made
                      to receive cash or as to which no election has been made will receive
                      $37.00 in cash. Each share of Raychem common stock as to which a share
                      election has been made will receive:

                        - 0.4140 X 0.8333 = 0.3450 of a Tyco common share, and

                        - cash equal to the per share value of the merger consideration less
                          the value of this fraction of a Tyco common share, or
                          $37.00 - ($89.375 X 0.3450) = $6.17.
</TABLE>

    CASE 3: THE NUMBER OF SHARES AS TO WHICH NO ELECTION IS MADE IS SUFFICIENTLY
    LARGE SO THAT THE CASH CONSIDERATION ELECTED IS LESS THAN THE CASH AVAILABLE
    FOR PAYMENT AND THE STOCK CONSIDERATION ELECTED IS LESS THAN THE NUMBER OF
    TYCO COMMON SHARES AVAILABLE FOR DELIVERY

    In this case, Tyco will calculate a proration factor for the shares that
make no election. This proration factor will equal (1) the difference between
the total number of shares of Raychem common stock that must receive cash less
the total number of Raychem shares that have elected cash divided by (2) the
total number of shares of Raychem common stock as to which no election has been
made. The total number of shares that must receive cash is determined by
dividing the total cash available for payment by the per share value of the
merger consideration.

    - Each share of Raychem common stock electing cash will be exchanged for
      cash in the amount of the per share value of the merger consideration;

    - Each share of Raychem common stock electing stock will be exchanged for a
      fraction of a Tyco common share having a value equal to the per share
      value of the merger consideration; and

    - Each share of Raychem common stock as to which no election has been made
      will be exchanged for:

     1.  cash equal to the per share value of the merger consideration
        multiplied by the proration factor; and

     2.  a fraction of a Tyco common share having a value equal to the per share
        value of the merger consideration less the amount of cash.

<TABLE>
<S>        <C>        <C>
           EXAMPLE:   Assume for this example that cash is elected with respect to 40% of the
                      shares of Raychem common stock, Tyco shares are elected with respect to
                      40% of the Raychem shares and no election is made with respect to 20% of
                      the Raychem shares. The non-electing share proration factor will be:

                        (($1,480,000,000  DIVIDED BY $37.00) - 32,000,000)  DIVIDED BY
                        16,000,000 = 0.5.

                      Each share of Raychem common stock as to which a cash election has been
                      made will be exchanged for $37.00. Each share of Raychem common stock as
                      to which a stock election has been made will be exchanged for 0.4140 of
                      a Tyco common share. Each share as to which no election has been made
                      will be exchanged for:

                        - cash equal to $37.00 X 0.5 = $18.50, and
                        - a fraction of a Tyco common share equal to
                          ($37.00 - $18.50)  DIVIDED BY $89.375 = 0.2070.

<PAGE>
    The table in the Summary under the caption "Merger Consideration" provides
examples for the allocation of the merger consideration assuming different
values for the Tyco average share price and other assumptions that are described
there.

UNVESTED RESTRICTED STOCK

    Unvested shares of Raychem restricted stock held by Raychem employees that
do not vest at the time of the merger will not be exchanged for the merger
consideration in the manner described above. Instead, these shares will be
converted in the merger into the right to receive Tyco common shares only, at an
exchange ratio of 0.4140 Tyco common shares for each Raychem share, and the
restrictions applicable to the Raychem shares will continue to apply to the Tyco
common shares. Restricted Raychem shares that vest at the time of the merger
will be treated the same as all other shares of Raychem common stock outstanding
at the time of the merger.

DISSENTING SHARES

    If any Raychem stockholders properly exercise their right to seek appraisal
for their shares, these stockholders will not receive the merger consideration.
In this case, the amount of cash available for payment to Raychem stockholders
in the merger will be reduced by the number of Raychem shares as to which
appraisal rights have been exercised, multiplied by the per share value of the
merger consideration. For a description of appraisal procedures, see "Appraisal
Rights" beginning on page 40.

NON-ELECTING SHARES

    MERGER CONSIDERATION.  The shares of Raychem stockholders who do not submit
an election form prior to the election deadline will be treated as non-electing
shares. If Tyco (PA) or the exchange agent determine that any election was not
properly made, such election will have no force and effect, and the shares with
respect to which such election was made will be deemed to be non-electing
shares. Neither Tyco (PA) nor the exchange agent has any obligation to inform
any Raychem stockholder of any defect in the making of an election. If a
stockholder submits an election form with stock certificates and the election
form is defective, the certificates will be held by the exchange agent and
exchanged for the merger consideration to be received by holders of non-electing
shares after the merger is consummated. The stockholder will not need to
complete and deliver to the exchange agent a separate letter of transmittal
after the merger as described below. Tyco (PA) and the exchange agent reserve
the right to waive defects in an election form, including late delivery.
However, waiver of defects is in their sole discretion.

    EXCHANGE OF NON-ELECTING SHARES OF RAYCHEM COMMON STOCK.  As soon as
reasonably practicable after the consummation of the merger, the surviving
corporation will instruct the exchange agent to mail to each holder of record of
non-electing shares a letter of transmittal and instructions on surrendering
their certificates of Raychem common stock in exchange for the merger
reconsideration they are entitled to receive.

    Holders of certificates previously representing Raychem common stock will
not be paid dividends or distributions on any Tyco common shares they are
entitled to receive as merger consideration, and will not be paid cash in lieu
of a fractional Tyco common share, until the Raychem stock certificates are
surrendered for exchange. When the certificates are surrendered, any unpaid
dividends declared by Tyco after the consummation of the merger and any cash in
lieu of a fractional Tyco common share will be paid without interest.

    The exchange agent will deliver the merger consideration in exchange for
lost, stolen or destroyed certificates if the owner of such certificates signs
an affidavit of loss, theft or destruction, as appropriate. The surviving
corporation may also, in its discretion, require the holder of such lost, stolen
or destroyed certificates to deliver a bond in a reasonable sum as indemnity
against any claim that

                                       48
<PAGE>
might be made against the surviving corporation, Tyco or the exchange agent with
respect to alleged lost, stolen or destroyed certificates.

TREATMENT OF RAYCHEM EQUITY-BASED AWARDS

    The merger agreement provides that each option to purchase shares of Raychem
common stock issued to employees and directors of Raychem and outstanding at the
time the merger is completed will constitute an option to acquire the number of
Tyco shares, rounded down to the nearest whole Tyco share, determined by
multiplying the number of shares of Raychem common stock subject to such option
by 0.4140. In addition, the exercise price per Tyco share of such option will be
determined by dividing the exercise price per share of Raychem common stock
underlying such option by 0.4140, rounded up to a whole cent. At the time the
merger is completed, each holder of unvested Raychem restricted stock that does
not vest at the time of the merger will receive 0.4140 Tyco restricted shares
for each share of Raychem restricted stock held by such individual. Raychem
restricted stock which becomes vested as a result of the merger pursuant to the
terms of Raychem's Key Employee Retention and Severance Plan will be treated the
same as other outstanding Raychem common stock, and will receive the
consideration described above in "Merger Consideration."

    Tyco will reserve for issuance enough Tyco common shares for delivery upon
exercise of the outstanding Raychem stock options in accordance with the merger
agreement. As soon as practicable following consummation of the merger, Tyco
will register the Tyco common shares issuable upon exercise of the Raychem stock
options with the SEC to the extent such registration is required. Tyco will use
at least such efforts as are applied to Tyco's other stock options generally to
cause the effectiveness of such registration, and the current status of the
prospectus or prospectuses included in the relevant registration statements, to
be maintained as long as the Raychem stock options remain outstanding.

REPRESENTATIONS AND WARRANTIES

    Tyco, Tyco (PA) and Raychem have made various customary mutual
representations and warranties in the merger agreement about themselves and
their subsidiaries.

    In addition, Raychem represented that the Raychem Board of Directors, prior
to the execution of the merger agreement, authorized an amendment to the Raychem
Rights Agreement to render the Raychem Rights Agreement inapplicable to the
merger agreement and the transactions that it contemplates. Raychem
appropriately amended the Raychem Rights Agreement on May 19, 1999.

CONDUCT OF BUSINESS BY RAYCHEM

    Raychem has agreed that, prior to the consummation of the merger, Raychem
will conduct its business, and that of its subsidiaries, only in the ordinary
course of business and in a manner consistent with past practice. In this
regard, Raychem will use reasonable commercial efforts to preserve substantially
intact the business organization of Raychem and its subsidiaries; keep available
the services of the present officers, employees and consultants of Raychem and
its subsidiaries; and preserve the present relationships of Raychem and its
subsidiaries with customers, suppliers and other persons with which Raychem or
any of its subsidiaries has significant business relations. In particular,
unless the merger agreement provides otherwise or as previously disclosed to
Tyco (PA) by Raychem, Raychem has agreed that neither it nor any of its
subsidiaries, without the prior written consent of Tyco (PA), will:

    1.  amend or otherwise change Raychem's Amended and Restated Certificate of
       Incorporation or Bylaws;

                                       49

    2.  issue, dispose or encumber any shares of capital stock of any class, or
       any options, warrants, convertible securities or other rights of any kind

       or affiliates, subject to certain exceptions in the case of Raychem's
       equity-based incentive plans;

    3.  dispose of or encumber any assets of Raychem or any of its subsidiaries
       out of the ordinary course of business;

    4.  - declare or pay any dividend or other distribution on any of its
          capital stock, other than regular quarterly dividends,

       - split, combine or reclassify any of its capital stock or permit or
         propose the issuance of any other securities in respect of, in lieu of
         or in substitution for shares of its capital stock,

       - amend the terms or change the period of exercisability of, acquire, or
         permit any subsidiary to amend the terms of or to acquire, any of its
         or its subsidiaries' securities, or

       - settle or discharge any action brought or threatened against Raychem
         arising out of a stockholder equity interest in Raychem;

    5.  - make any acquisitions,

       - incur any indebtedness other than pursuant to credit facilities
         previously disclosed to Tyco,

       - authorize capital expenditures or purchases of fixed assets which are,
         in the aggregate, in excess of $50 million, or

       - enter into or amend any contract, agreement, commitment or arrangement
         to do any of the above;

    6.  - increase the compensation or severance payable or to become payable to
          its directors, officers or employees except in accordance with past
          practice,

       - grant severance or termination pay to any director, officer or
         employee,

       - enter into any employment or severance agreement with any new employee
         of Raychem which provides for annual base and bonus compensation in
         excess of $200,000,

       - enter into or modify any agreement with a director of Raychem, or

       - establish, adopt, enter into or amend any collective bargaining,
         employment, termination, severance or benefit plan, agreement, trust,
         fund, policy or arrangement for any current or former directors,
         officers or employees;

    7.  change accounting policies or procedures;

    8.  make any tax election or settle or compromise any United States federal,
       state, local or non-United States tax liability;

    9.  satisfy claims, liabilities or obligations out of the ordinary course of
       business;

    10. make any loan to any director, officer, employee or independent
       contractor of Raychem, except to effect a cashless exercise of a Raychem
       stock option; or

    11. take, or agree to take, any of the above actions or take or agree to
       take, any action which would make any of the representations or
       warranties of Raychem contained in the merger agreement untrue or
       incorrect or prevent Raychem from performing its covenants under the
       merger agreement.

    These restrictions have certain exceptions which are set forth in the merger
agreement.

                                       50
<PAGE>
CONDUCT OF BUSINESS BY TYCO

    Tyco has agreed that, prior to the consummation of the merger, it will
conduct its business and that of its subsidiaries in the ordinary course of
business and consistent with past practice, including actions taken by Tyco or
its subsidiaries in contemplation of the merger, and will not, without the prior
written consent of Raychem:

    1.  amend or otherwise change Tyco's Memorandum of Association or Bye-Laws;

    2.  make or agree to make any acquisition or disposition which would
       materially delay or prevent the consummation of the transactions
       contemplated by the merger agreement;

    3.  declare or pay any dividend or other distribution on any of its capital
       stock, other than regular quarterly dividends;

    4.  change accounting policies or procedures; or

    5.  take or agree to take, any action which would make any of the
       representations or warranties of Tyco contained in the merger agreement
       untrue or incorrect or prevent Tyco from performing its covenants under
       the merger agreement.

NO SOLICITATION

    Raychem has agreed that it will not solicit or encourage the initiation of
any inquiries or proposals regarding any other consolidation, business
combination, recapitalization or similar transaction, including any transaction
with a third party in which such party would acquire more than a 20% interest in
any class of Raychem's equity securities or in the outstanding equity of the
surviving entity in a merger with Raychem or would acquire more than 20% of the
fair market value of Raychem's assets. Any of the foregoing transactions are
referred to in this document as an "Alternative Transaction," and any proposal
from a third party to effect an Alternative Transaction is referred to as an
"Acquisition Proposal."

    Until the Raychem stockholders approve and adopt the merger agreement, if
the Raychem Board, following consultation with independent legal counsel,
determines that such action is reasonably likely to be required to discharge
properly its fiduciary duties, the Raychem Board, after notice to Tyco, is
permitted to:

    1.  furnish information to a third party which has made, but was not
       solicited in violation of the merger agreement to make, a "Superior
       Proposal." A "Superior Proposal" is defined as a BONA FIDE Acquisition
       Proposal to acquire for cash and/or securities, all of the voting equity
       securities of Raychem or all or substantially all of Raychem's assets, on
       terms which the Raychem Board reasonably believes are more favorable than
       the merger:

    - from a financial point of view to Raychem stockholders, after consultation
      with a nationally recognized financial advisor, taking into account at the
      time of determination any changes to the financial terms of the merger
      proposed by Tyco, and

    - to Raychem, taking into account all pertinent factors deemed relevant by
      the Raychem Board under the laws of Delaware; and

    2. consider and negotiate such Superior Proposal.

    Raychem and the Raychem Board may not withdraw or modify in a manner adverse
to Tyco or Tyco (PA) the Raychem Board's approval of the merger, except to the
extent that the Raychem Board reasonably determines in good faith and after
consultation with independent legal counsel that it is reasonably likely to be
required to do so in order to properly discharge its fiduciary duties.

                                       51
<PAGE>
    In addition, unless the merger agreement has been terminated in accordance
with its terms, the merger agreement must be submitted for approval and adoption
by the Raychem stockholders at the Raychem special meeting, and the Raychem
Board may not recommend that stockholders vote against approval of the merger
and adoption of the merger agreement.

    The merger agreement expressly provides that the foregoing covenants shall
not prohibit Raychem from taking or disclosing to its stockholders a position
regarding an Alternative Transaction or Acquisition Proposal required by the
SEC's tender offer rules or from making any disclosure to its stockholders
required by law.

    Raychem has agreed:

    1.  to cease any discussions or negotiations with any third party that were
       ongoing at the time of the execution of the merger agreement;

    2.  not to release any third party from the confidentiality and standstill
       provisions of any agreement to which Raychem is a party; and

    3.  not to redeem the rights under, or waive or amend any provisions of, the
       Raychem Rights Agreement that would facilitate the consummation of any
       Acquisition Proposal or Alternative Transaction.

    Raychem will ensure that the officers and directors of Raychem and its
subsidiaries and any investment banker or other advisor or representative
retained by Raychem are aware of the no-solicitation restrictions described in
the merger agreement.

CERTAIN OTHER COVENANTS

CONSENTS; APPROVALS

    Tyco, Tyco (PA) and Raychem will each use its reasonable best efforts to
obtain all consents, waivers, approvals, authorizations or orders, and Tyco,
Tyco (PA) and Raychem will make all filings, required in connection with the
authorization, execution and delivery of the merger agreement and the
consummation by each of them of the transactions contemplated thereby.

INDEMNIFICATION AND INSURANCE

    For six years following consummation of the merger, the Articles of
Incorporation and By-laws of the surviving corporation will contain the same
indemnification provisions as currently in the Certificate of Incorporation of
Raychem and such provisions will not be modified in any manner adverse to those
individuals who were directors, officers or employees of Raychem at the
consummation of the merger.

    After consummation of the merger, the surviving corporation will, to the
fullest extent permitted under applicable law or under its Articles of
Incorporation or By-laws, indemnify and hold harmless each present and former
director, officer or employee of Raychem or any of its subsidiaries against any
costs or expenses, judgments, fines, losses, claims, damages, liabilities and
amounts paid in settlement in connection with any claim, action, suit,
proceeding or investigation, whether civil, criminal, administrative or
investigative, arising out of or pertaining to the transactions contemplated by
the merger agreement, or otherwise with respect to any acts or omissions
occurring at or prior to the consummation of the merger, to the same extent as
provided in Raychem's Articles of Incorporation or By-laws or any applicable
contract or agreement as in effect on the date of the merger agreement, in each
case for a period of six years after the date of the merger agreement.

    Following the merger, the surviving corporation will continue to honor in
all respects Raychem's obligations under the indemnification agreements and
employment agreements with Raychem's officers and directors existing at or
before consummation of the merger.

                                       52
<PAGE>
    Tyco will provide, or cause the surviving corporation to provide, for a
period of not less than six years after consummation of the merger, Raychem's
current directors and officers an insurance and indemnification policy for
events occurring at or prior to consummation of the merger that is no less
favorable than Raychem's existing policy or, if substantially equivalent
insurance coverage is unavailable, the best available coverage. Tyco and the
surviving corporation will not, however, be required to pay an annual insurance
premium in excess of 200% of the annual premium currently paid by Raychem for
such insurance, but in such case will purchase as much coverage as possible for
such amount.

NOTIFICATION OF CERTAIN MATTERS

    Tyco, Tyco (PA) and Raychem will each give each other prompt notice of the
occurrence or nonoccurrence of any event which would be reasonably expected to
cause any representation or warranty of the notifying party contained in the
merger agreement to be materially untrue or inaccurate, or any failure of the
notifying party materially to comply with any covenant, condition or agreement
in the merger agreement.

FURTHER ACTION/TAX TREATMENT

    Tyco, Tyco (PA) and Raychem will use all reasonable efforts to take, or
cause to be taken, all actions and do other things necessary, proper or
advisable to consummate as promptly as practicable the transactions contemplated
by the merger agreement, to obtain in a timely manner all necessary waivers,
consents and approvals and to effect all necessary registrations and filings,
and otherwise to satisfy or cause to be satisfied all conditions precedent to
each of their obligations under the merger agreement. However, Tyco is under no
obligation to agree to divest, abandon, license or take similar action with
respect to any material assets of Tyco or Raychem. The merger agreement defines
"material" for these purposes as any assets to which are attributable annual
sales in an amount equal to 1% or more of Raychem's annual sales in fiscal year
1998. In addition, the parties have each agreed to use their reasonable best
efforts to cause the merger to qualify as a reorganization under the provisions
of Section 368 of the U.S. Internal Revenue Code, as specified in the merger
agreement, and will not, both before and after consummation of the merger, take
any actions which to their knowledge could reasonably be expected to prevent the
merger from so qualifying. Raychem has the option of proceeding with the
acquisition by Tyco even if the merger does not so qualify as a reorganization.
See "Conditions to the Merger--Failure to Deliver Tax Opinions" on page 56.

PUBLIC ANNOUNCEMENTS

    Tyco and Raychem will not issue any press release or make any public written
statement with respect to the merger or the merger agreement without the prior
consent of the other party, which consent will not be unreasonably withheld,
except as required by law or the regulations of the NYSE.

TYCO COMMON SHARES

    Tyco will transfer to Tyco (PA) the Tyco common shares to be delivered to
the Raychem stockholders in the merger. Tyco has agreed to use its best efforts
to list the shares on the NYSE prior to the time the merger becomes effective.

EMPLOYEE MATTERS

    Subject to the limitations contained in the merger agreement, Tyco, Tyco
(PA) and Raychem have agreed to a number of covenants regarding the treatment of
employee and retiree benefits following the consummation of the merger,
including the following:

    - Raychem will terminate its stock purchase plans as of the consummation of
      the merger.

                                       53
<PAGE>
    - Through June 30, 2000, Tyco and Tyco (PA) will provide:

    1.  those persons who, immediately prior to the merger, were employees of
       Raychem or its subsidiaries, and who continue their employment with the
       surviving corporation following the merger, employee welfare and
       retirement benefits that in the aggregate are substantially equivalent to
       those benefits provided by Raychem immediately prior to the merger. For
       this purpose, service accrued by these employees with Raychem or its
       subsidiaries prior to the merger will be recognized except to the extent
       necessary to prevent duplication of benefits; and

    2.  any person who immediately prior to the merger is a retiree under a
       Raychem retiree medical program with retiree medical benefits that in the
       aggregate are substantially equivalent to those provided by Raychem
       immediately prior to the merger.

    Subject to 1 and 2 above, Tyco (PA) can amend any Raychem retiree benefit
    plan, with respect to any Raychem employee, upon consummation of the merger,
    and with respect to any Raychem retiree, effective July 1, 2000.

    - Tyco and Tyco (PA) will assume and maintain Raychem's Key Employee
      Retention and Severance Plan. In addition, Tyco and Tyco (PA) will assume,
      and through June 30, 2000, maintain, Raychem's Executive Termination
      Compensation Policy and Lay-Off Benefits Plan.

    - Tyco and Tyco (PA) have agreed to honor deferral elections made on or
      prior to June 30, 1999 under Raychem's deferred compensation plans. Tyco
      and Tyco (PA) have further agreed to continue and maintain Raychem's loan
      program through June 30, 2000 and to honor the terms of loans previously
      made under this program.

The merger agreement provides that the foregoing provisions are not enforceable
by persons not parties to the merger agreement.

RIGHTS AGREEMENT

    The Raychem Board has agreed to take all necessary action to render the
rights under the Raychem Rights Agreement inapplicable to the merger agreement
and the merger.

CONDITIONS TO THE MERGER

    warranties of Raychem in the merger agreement are true and correct in all
    material respects on and as of the date of the consummation of the merger,
    with the same force and effect as if made on and as of the date of the

    Agreement, has not occurred under the Raychem Rights Agreement.

ADDITIONAL CONDITIONS TO OBLIGATION OF RAYCHEM

    The obligation of Raychem to complete the merger is also subject to the
following conditions:

1.  REPRESENTATIONS AND WARRANTIES. Except as would not reasonably be expected
    to have a material adverse effect on Tyco and Tyco (PA), the representations
    and warranties of Tyco and Tyco (PA) contained in the merger agreement are
    true and correct in all material respects at and as of the

                                       55
<PAGE>
    consummation of the merger, with the same force and effect as if made on and

2.  AGREEMENTS AND COVENANTS. Tyco and Tyco (PA) have performed or complied in
    all material respects with all agreements and covenants required by the

    in connection with the merger; and

5.  TYCO SHAREHOLDERS RIGHTS PLAN. A Distribution Date, as defined in the Tyco

FAILURE TO DELIVER TAX OPINIONS

    In the event that:

    - PricewaterhouseCoopers LLP notifies Tyco and Tyco (PA) that it cannot
      render the Tyco tax opinion, or

    - Shearman & Sterling notifies Raychem that it cannot render the Raychem tax
      opinion,

Raychem, within three business days of receipt of such notice, may elect to
require Tyco to proceed with the acquisition of Raychem on a taxable basis. In
such event, the condition of receiving tax opinions shall be deemed waived.
Tyco, Tyco (PA) and Raychem will then take all necessary steps to effectuate a
merger of a wholly owned subsidiary of Tyco with and into Raychem, as the
surviving corporation, in accordance with the provisions of the Delaware General
Corporation Law. Except as may be necessary to reflect the change in the
structure of the merger and the jurisdiction of the Tyco subsidiary
participating in the merger, the terms of the merger agreement will still
govern.

TERMINATION

CONDITIONS TO TERMINATION.

    The merger agreement may be terminated at any time prior to the consummation
of the merger, notwithstanding the approval of the merger by the Raychem
stockholders:

1.  by mutual written consent duly authorized by the Boards of Directors of both
    Raychem and Tyco;

2.  by either of Tyco or Raychem, if the merger has not been consummated by
    November 30, 1999, other than for reasons set forth in 4 below, provided
    that this right to terminate is not available to the party whose failure to
    fulfill any of its obligations under the merger agreement caused the merger
    not to be consummated by November 30, 1999;

3.  by either of Tyco or Raychem, if a court of competent jurisdiction or
    governmental, regulatory or administrative agency or commission issues a
    nonappealable final order, decree or ruling or takes any other action which
    permanently prohibits the merger;

                                       56
<PAGE>
4.  by either of Tyco or Raychem, if a meeting of Raychem's stockholders to vote
    on the merger agreement is not held by November 30, 1999 or if the Raychem
    stockholders do not approve the merger at the Raychem special meeting;

5.  by Tyco, if, whether or not permitted to do so by the merger agreement,
    Raychem or the Raychem Board:

    - withdraws or changes its approval or recommendation of the merger
      agreement or the merger in a manner adverse to Tyco,

    - approves or recommends to the stockholders of Raychem an Acquisition
      Proposal or Alternative Transaction,

      Raychem stockholders at the Raychem special meeting,

    - the Raychem Board reasonably determines in good faith, following
      consultation with independent legal counsel, that it is reasonably likely
      to be required to accept such proposal in order to discharge properly its
      fiduciary duties,

    - Raychem in fact accepts the Superior Proposal, and

    - Raychem complies in all material respects with its no solicitation
      obligations as described on page 51; or

7.  by either of Tyco or Raychem:

    - if any representation or warranty of the other party set forth in the
      merger agreement is untrue when made,

    - if any representation or warranty of the other party set forth in the
      merger agreement becomes untrue, or

    - upon a breach of any covenant or agreement set forth in the merger
      agreement by the other party,

    such that in each case, the conditions to the terminating party's obligation
    to complete the merger described above under "Conditions to the Merger"
    would not be satisfied. If such misrepresentation or breach is curable prior
    to November 30, 1999 and the party in breach exercises its reasonable best
    efforts to cure the same, the merger agreement may not be terminated under
    these provisions while such party continues to exercise such efforts.

FEES AND EXPENSES.

    Except as set forth below, each of Tyco, Tyco (PA) or Raychem will pay its
own fees and expenses incurred in connection with the merger agreement and the
merger, whether or not the merger is completed, PROVIDED that Tyco and Raychem
will share equally all filing fees and printing expenses incurred in connection
with the printing and filing of this document and the related registration
statement.

<PAGE>
    Raychem will pay Tyco a fee of $100 million, and will pay Tyco's and Tyco
(PA)'s actual, documented and reasonable out-of-pocket expenses relating to the
merger of up to $7.5 million, upon the first to occur of any of the following
events:

1.  the termination of the merger agreement by Tyco or Raychem because the
    meeting of stockholders of Raychem to approve the merger has not been held
    by November 30, 1999, or due to the failure of the Raychem stockholders to
    approve the merger at the Raychem special meeting, if:

    - at the time of the Raychem special meeting, an Acquisition Proposal is
      made directly to the Raychem stockholders or otherwise becomes publicly
      known or a credible third party has announced a BONA FIDE intention to
      make such an Acquisition Proposal, or

    - within 12 months following the date of termination of the merger
      agreement, an Alternative Transaction is publicly announced by Raychem or
      any third party and such transaction is at any time thereafter consummated
      on substantially the terms previously announced.

2.  the termination of the merger agreement by Tyco due to the Raychem Board's
    approval or recommendation of an Acquisition Proposal or Alternative
    Transaction or its approval or recommendation to Raychem stockholders to
    tender their shares in an Alternative Transaction;

3.  the termination of the merger agreement by Raychem due to the Raychem Board
    accepting a Superior Proposal as permitted by the merger agreement and
    described in paragraph 6 under "Conditions to Termination" above.

4.  the termination of the merger agreement by Tyco due to Raychem's willful
    breach of a covenant or agreement set forth in the merger agreement, if:

    - at the time of the breach by Raychem, an Acquisition Proposal is made
      directly to the Raychem stockholders or otherwise becomes publicly known
      or a credible third party has announced a BONA FIDE intention to make such
      an Acquisition Proposal, or

    - within 12 months following the date of termination of the merger
      agreement, an Alternative Transaction is publicly announced by Raychem or
      any third party and such transaction is at any time thereafter consummated
      on substantially the terms previously announced.

    Raychem is required to pay to Tyco and Tyco (PA) for their respective
expenses relating to the merger, but in no event more than $7.5 million upon a
termination of the merger agreement by Tyco as a result of a representation or
warranty of Raychem being untrue when made, as described in paragraph 7 under
"Conditions to Termination" above.

    Tyco (PA) is required to pay to Raychem for the expenses of Raychem relating
to the merger, but in no event more than $7.5 million, upon termination of the
merger agreement by Raychem as a result of a representation or warranty by Tyco
or Tyco (PA), being untrue when made, as described in paragraph 7 under
"Conditions to Termination" above.

    The fee and/or expenses are payable within one business day after a demand
for payment following the occurrence of the event requiring such payment.
However, in no event will a party be required to pay such fee and/or expenses to
the other if, immediately prior to the termination of the merger agreement, the
party to receive the fee and/or expenses was in material breach of its
obligations, representations or warranties under the merger agreement.

    The fee payable under certain circumstances by Raychem to Tyco is intended,
among other things, to compensate Tyco for its costs, including lost opportunity
costs, if certain actions or inactions by Raychem or its stockholders lead to
the abandonment of the merger. This may have the effect of increasing the
likelihood of consummation of the merger in accordance with the terms of the
merger agreement. The fee may also have the effect of discouraging persons from
making an offer to acquire all of or a significant interest in Raychem by
increasing the cost of any such acquisition.

AMENDMENT AND WAIVER; PARTIES IN INTEREST

    Tyco, Tyco (PA) and Raychem may amend the merger agreement in writing by
action taken by or on behalf of their respective Boards of Directors at any time
prior to consummation of the merger. However, after approval of the merger by
the stockholders of Raychem, the merger agreement cannot be amended without the
necessary stockholder approval as required by law.

    At any time prior to consummation of the merger, any of Tyco, Tyco (PA) and
Raychem may extend the time for the performance of any of the obligations or
other acts by the other, waive any inaccuracies in the representations and
warranties contained in the merger agreement or in any document delivered
pursuant to the merger agreement, or, to the extent allowed by law, waive
compliance with any of the agreements or conditions contained in the merger
agreement. Any such extension or waiver will be valid if set forth in writing by
the party or parties granting such extension or waiver.

    The merger agreement is binding upon and inures solely to the benefit of the
parties thereto, and nothing in the merger agreement confers upon any other
person any right, benefit, remedy or obligation, other than the indemnification,
employment and insurance obligations of Tyco and the surviving corporation
following consummation of the merger, which are intended for the benefit of
certain specified officers, directors and employees of Raychem and may be
enforced by such individuals.

          UNAUDITED PRO FORMA COMBINED CONDENSED FINANCIAL INFORMATION

    The merger is to be accounted for in accordance with the purchase method of
accounting pursuant to APB Opinion No. 16. Accordingly, the accompanying
unaudited pro forma combined condensed financial information gives effect to the
transaction in accordance with the purchase method of accounting. Pursuant to
Rule 11-02 of Regulation S-X, the unaudited pro forma combined condensed
financial information excludes the results of extraordinary items.

    The unaudited pro forma combined condensed financial information should be
read in conjunction with:

        1. Tyco's audited September 30, 1998 supplemental consolidated financial
    statements, including the accounting policies and notes thereto, and Tyco's
    unaudited March 31, 1999 supplemental consolidated financial statements and
    notes thereto, both of which are included in Tyco's Current Report on Form
    8-K filed on June 3, 1999,

        2. Raychem's audited consolidated financial statements, including the
    accounting policies and notes thereto, included in its annual report on Form
    10-K for the fiscal year ended June 30, 1998, and

        3. Raychem's unaudited consolidated financial statements and notes
    thereto included in its quarterly reports on Form 10-Q for the quarterly
    periods ended September 30, 1998, December 31, 1998 and March 31, 1999.

    The following unaudited pro forma combined condensed financial information
sets forth the results of operations for the fiscal year ended September 30,
1998 and the six months ended March 31, 1999, as if the merger had occurred at
the beginning of fiscal 1998 and the financial position as of March 31, 1999 as
if the merger had occurred as of that date. Raychem has a June 30 fiscal year
end, which differs from Tyco's September 30 fiscal year end. The unaudited pro
forma combined condensed statements of continuing operations for the fiscal year
ended September 30, 1998 and the six months ended March 31, 1999 include the
historical results of operations for Raychem for the fiscal year ended June 30,
1998 and the six months ended December 31, 1998, respectively. The unaudited pro
forma combined balance sheet includes the financial position of Raychem at March
31, 1999.

    The unaudited pro forma combined condensed financial information has been
prepared in accordance with generally accepted accounting principles in the
United States. These principles require management to make extensive use of
estimates and assumptions that affect the reported amounts of assets and
liabilities and disclosure of contingent assets and liabilities at the date of
the consolidated financial statements and the reported amounts of revenues and
expenses during the reporting period. Actual results could differ from those
estimates. The unaudited pro forma combined condensed results of operations are
not necessarily indicative of future operating results.

                          NOTES TO UNAUDITED PRO FORMA
                    COMBINED CONDENSED FINANCIAL INFORMATION

(1) Raychem has a June 30 fiscal year end, which differs from Tyco's September
    30 fiscal year end. The pro forma results of operations for the fiscal year
    ended September 30, 1998 and the six months ended March 31, 1999 include the
    historical results of Raychem for the fiscal year ended June 30, 1998 and
    the six months ended December 31, 1998, respectively. The pro forma balance
    sheet includes the financial position of Raychem at March 31, 1999.

(2) The pro forma combined per share amounts are based on the pro forma combined
    weighted average number of common shares which equals Tyco's weighted
    average number of common shares outstanding for the period plus the total
    number of Tyco common shares that will be delivered to Raychem stockholders
    in the merger. The number of shares to be delivered in the merger is fixed
    at 0.2070 multiplied by the number of Raychem common shares outstanding at
    the time of the merger. For purposes of the pro forma combined condensed
    financial information, 77,585,116 Raychem common shares outstanding as of
    May 18, 1999 was assumed.

(3) Certain reclassifications, none of which affects income from continuing
    operations, have been made to the Raychem statements of operations in the
    pro forma combined condensed statements of continuing operations to classify
    research and development expenses and interest income on a consistent basis.
    The pro forma adjustments to the balance sheet were required to classify on
    a consistent basis goodwill and other intangibles, long-term investments,
    deferred income taxes and deferred revenue.

(4) Diluted income per common share from continuing operations for Tyco, after
    adding Liquid Yield Option Notes ("LYONs") discount amortization, was based
    on adjusted income from continuing operations available to common
    shareholders of $56.7 million for the six months ended March 31, 1999 and
    $1,175.8 million for the year ended September 30, 1998.

(5) There were no material transactions between Tyco and Raychem during any of
    the periods presented.

(6) During the six months ended March 31, 1999, Tyco recorded $841.0 million of
    merger, restructuring and other non-recurring charges, consisting of $434.9
    million primarily related to the merger with US Surgical and $406.1 million
    related to AMP's operations. In addition, Tyco recorded $143.6 million for
    the impairment of long-lived assets, consisting of $76.0 million primarily
    related to the merger with US Surgical and $67.6 million related to AMP's
    operations.

(7) During the fiscal year ended September 30, 1998, Tyco recorded charges of
    $80.5 million primarily related to costs to exit certain businesses in US
    Surgical's operations and restructuring charges of $12.0 million related to
    the operations of US Surgical. In addition, Tyco recorded restructuring
    charges of $185.8 million in connection with AMP's profit improvement plan
    and a credit of $21.4 million to restructuring charges related to the
    execution of AMP's 1996 restructuring plans. During the fiscal year ended
    June 30, 1998, Raychem recorded restructuring charges of $27.6 million
    associated with moving certain manufacturing facilities to lower-cost
    locations. In addition, Raychem recorded a non-recurring charge of $12.0
    million reflecting the write-off of assets related to a minority investment.

(8) The allocation of the purchase price to the fair value of assets and
    liabilities of Raychem has not yet been determined. Therefore, for purposes
    of the pro forma combined condensed financial information, the excess of the
    purchase price over the book value of net assets acquired of Raychem is
    being recorded as goodwill, which is amortized over a period of 40 years to
    selling, general and administrative expenses.

(9) Increase in interest expense due to the borrowing of long-term debt used to
    make the cash payment of approximately $1.44 billion to acquire Raychem,
    calculated using Tyco's average borrowing rate of 5.13%.

(10) Income tax benefit associated with the interest expense adjustment in (9)
    above, calculated at the statutory income tax rate of 35%.

(11) Excess of the purchase price over the net assets acquired of Raychem. See
    (8) above for further discussion.

(12) Increase in accrued expenses for direct transaction costs incurred related
    to the merger.

(13) Increased borrowings used to make the cash payment to acquire Raychem.

                      COMPARISON OF RIGHTS OF STOCKHOLDERS
                      OF RAYCHEM AND SHAREHOLDERS OF TYCO

    Raychem is a Delaware corporation, and the rights of Raychem's stockholders
are governed by Raychem's Certificate of Incorporation and Bylaws and by
Delaware law. Upon the consummation of the merger, stockholders of Raychem, to
the extent that they receive Tyco common shares, will become shareholders of
Tyco, and their rights will be governed by Tyco's Memorandum of Association and
Bye-laws and by Bermuda law.

    The following is a summary comparison of the material differences between
the rights of a Raychem stockholder and a Tyco shareholder arising from the
differences between the corporate laws of Delaware and of Bermuda and the
governing instruments of the two companies. The summary is not a complete
description of those laws or governing instruments.

    Copies of Tyco's Memorandum of Association and Bye-laws and Raychem's
Certificate of Incorporation and Bylaws have been filed with the SEC and will be
sent to holders of Raychem common stock upon request. See "Where to Find More

                                            for relief, and the court has a wide
                                            discretion to grant relief if it is
                                            satisfied that the complaint is

                          FUTURE STOCKHOLDER PROPOSALS

    Due to the contemplated consummation of the merger, Raychem does not
currently expect to hold a 1999 annual meeting of stockholders because Raychem
will be an indirect wholly owned subsidiary of Tyco following the merger. In the
event the merger is not consummated, proposals of Raychem stockholders to be
included in the proxy statement to be mailed to all Raychem stockholders
entitled to vote at the 1999 Annual Meeting of Raychem stockholders must have
been received at Raychem's principal executive offices no later than May 21,
1999. In addition, under Raychem's Bylaws, business to be brought before the
1999 annual meeting must be submitted in writing to the Corporate Secretary of
Raychem no later than August 8, 1999 and no earlier than July 9, 1999. These
dates would change if the 1999 annual meeting were not held within specified
time periods of the first anniversary of the 1998 annual meeting of Raychem
stockholders.

                AGREEMENT AND PLAN OF MERGER AND REORGANIZATION

    AGREEMENT AND PLAN OF MERGER AND REORGANIZATION, dated as of May 19, 1999
(this "AGREEMENT"), among Tyco International Ltd. , a Bermuda company
("PARENT"), Tyco International (PA) Inc., a Nevada corporation and a direct,
wholly-owned subsidiary of Parent ("MERGER SUB"), and Raychem Corporation, a
Delaware corporation (the "COMPANY").

                              W I T N E S S E T H:

    WHEREAS, the Boards of Directors of Parent, Merger Sub and the Company have
each determined that it is advisable and in the best interests of their
respective shareholders, and consistent with and in furtherance of their
respective business strategies and goals, for Parent to acquire all of the
outstanding shares of the Company through the merger of the Company with Merger
Sub or such other entity as provided in Section 6.04 upon the terms and subject
to the conditions set forth herein;

    WHEREAS, in furtherance of such combination, the Boards of Directors of
Parent, Merger Sub and the Company have each approved the merger (the "MERGER")
of the Company with Merger Sub or such other entity as provided in Section 6.04,
in accordance with the applicable provisions of the Nevada General Corporation
Law (the "NGCL") and the Delaware General Corporation Law (the "DGCL"), or such
other jurisdiction as appropriate in accordance with the provisions of Section
6.04, and upon the terms and subject to the conditions set forth herein;

    WHEREAS, Parent, Merger Sub and the Company intend, by approving resolutions
authorizing this Agreement, to adopt this Agreement as a plan of reorganization
within the meaning of Section 368 of the United States Internal Revenue Code of
1986, as amended (the "CODE"), and the regulations promulgated thereunder, and
that the transactions contemplated by this Agreement be undertaken pursuant to
such plan except as otherwise provided in Section 6.04; and

    WHEREAS, pursuant to the Merger, each outstanding share (together with the
preferred stock purchase right associated therewith, a "SHARE") of the Company's
Common Stock, par value $1.00 (the "COMPANY COMMON STOCK"), other than shares
owned directly or indirectly by the Parent, Merger Sub or the Company and other
than Dissenting Shares (as defined in Section 1.13) will be converted into the
right to receive the Merger Consideration (as defined in Section 1.07(b)), upon
the terms and subject to the conditions set forth herein.

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

                                   ARTICLE I

    Section 1.01.  THE MERGER.  At the Effective Time (as defined in Section
1.02), and subject to and upon the terms and conditions of this Agreement, the
NGCL and the DGCL, the Company shall be merged with and into Merger Sub, the
separate corporate existence of the Company shall cease and Merger Sub shall
continue as the surviving corporation. Merger Sub as the surviving corporation
after the Merger is hereinafter sometimes referred to as the "SURVIVING
CORPORATION."

    Section 1.02.  EFFECTIVE TIME.  Unless this Agreement shall have been

in Article VI, the parties hereto shall cause the Merger to be consummated by
(a) filing articles of merger as contemplated by the NGCL (the "ARTICLES OF
MERGER") and (b) filing a certificate of merger as contemplated by the DGCL (the

related certificates, with the Secretaries of State of the States of Nevada and
Delaware, as appropriate, in such forms as required by, and executed in
accordance with, the relevant provisions of the NGCL and the DGCL, respectively.
The Merger shall become effective at the time of the later to occur of such
filings or at such later time as agreed to by each of the parties hereto in
writing, which will be as soon as reasonably practicable, specified in the
Articles of Merger and Certificate of Merger (the "EFFECTIVE TIME"). Prior to
such filings, a closing shall be held at the offices of Kramer Levin Naftalis &
Frankel LLP, 919 Third Avenue, New York, NY, unless another time or place is
agreed to in writing by the parties hereto, for the purpose of confirming the
satisfaction or waiver, as the case may be, of the conditions set forth in
Article VI.

by the NGCL and such Articles of Incorporation.

    (b) BYLAWS. Subject to the provisions of Section 5.06(a), the By-Laws of

    the Average Share Price multiplied by 0.2070 (such fraction, the "SHARE
    RATIO").

converted into the right to receive from Merger Sub a fraction of a Parent
Common Share, cash or a combination of a fraction of a Parent Common Share and
cash as hereinafter provided.

    (B) The total amount of cash that Merger Sub will pay to Company
stockholders in the Merger under this Section 1.06(a) is the product of $18.50
multiplied by the number of shares of Company Common Stock outstanding at the

Shares multiplied by the Closing Per Share Amount. The total number of Parent
Common Shares that Merger Sub will transfer to Company stockholders in the
Merger under this Section 1.06(a) is 0.2070 multiplied by the number of shares
of Company Common Stock outstanding at the Effective Time.

    (C) Shares of restricted stock that do not vest as a result of the

treated as outstanding and are not included in determining the number of shares

    Parent Common Share equal to the Closing Per Share Amount divided by the
    Average Share Price;

        (2) each Cash Electing Share shall be converted into the right to
    receive (I) cash equal to the Closing Per Share Amount multiplied by the
    Cash Proration Factor and (II) a fraction of a Parent Common Share equal to
    (x) the Closing Per Share Amount divided by the Average Share Price
    multiplied by (y) one minus the Cash Proration Factor; and

        (3) each Non-Electing Share shall be converted into the right to receive
    a fraction of a Parent Common Share equal to the Closing Per Share Amount
    divided by the Average Share Price.

    (v) EXCESS OF STOCK ELECTING SHARES. If the number of Stock Electing Shares
exceeds the Number of Share Exchange Shares,

    Share Amount divided by the Average Share Price multiplied by (y) the Stock
    Proration Factor and (II) cash equal to (x) the Closing Per Share Amount
    multiplied by (y) one minus the Stock Proration Factor; and

        (3) each Non-Electing Share shall be converted into the right to receive
    cash equal to the Closing Per Share Amount.

    (vi) NO EXCESS OF CASH ELECTING OR STOCK ELECTING SHARES. In the event that
neither Section 1.06(a)(iv) nor 1.06(a)(v) above is applicable,

        (1) each Cash Electing Share shall be converted into the right to
    receive cash equal to the Closing Per Share Amount;

        (2) each Stock Electing Share shall be converted into the right to
    receive a fraction of a Parent Common Share equal to the Closing Per Share
    Amount divided by the Average Share Price; and

        (3) each Non-Electing Share shall be converted into the right to receive
    (I) cash in the amount of (x) the Closing Per Share Amount multiplied by (y)
    the Cash Deficiency Ratio and (II) a fraction of a Parent Common Share equal
    to (x) the Closing Per Share Amount divided by the Average Stock Price
    multiplied by (y) the Stock Deficiency Ratio.

   (vii) EXERCISE OF ELECTION. All elections in accordance with this Section
1.06(a) shall be made on a form designed for that purpose and mutually

when the Effective Time shall occur) (a "FORM OF ELECTION") and mailed to

Stockholders Meeting (as defined in Section 2.13) or such other date as Merger
Sub and the Company shall mutually agree (the "ELECTION FORM RECORD DATE") or,

transmission of an Agent's Message (as hereinafter defined). Merger Sub and the
Company shall make available one or more Forms of Election as may be reasonably
requested by all persons who become holders (or beneficial

<PAGE>
owners) of Company Common Stock between the Election Form Record Date and the

Elections shall be made by submitting to the Exchange Agent in accordance with
Section 1.06(a)(viii) either (A) a properly completed and signed Form of

Common Stock as to which the election is being made (or an appropriate guarantee
of delivery by an Eligible Guarantor Institution, as that term is defined in
Rule 17Ad-15 promulgated pursuant to the Exchange Act (as defined in Section
2.05)) or (B) in the case of shares of Company Common Stock held in book-entry

The term "AGENT'S MESSAGE" means a message transmitted by DTC and received by
the Exchange Agent and forming part of the confirmation of a book-entry transfer
which states that DTC has received an express acknowledgment from a participant
transmitting the shares of Company Common Stock, sets forth the election being
made with respect to such shares and states that such participant has agreed to
be bound by the terms of the Form of Election with respect to such shares.
Merger Sub will have the discretion, which it may delegate in whole or in part
to the Exchange Agent, to reasonably determine whether Forms of Election have
been properly completed, signed and submitted or revoked and to disregard
immaterial defects in Forms of Election, or, in the case of shares of Company
Common Stock held in book-entry form, whether an Agent's Message has properly
been received or whether any modifications of the procedures set forth in this
Section 1.06(a)(vii) or in Section 1.06(a)(viii) are necessary to comply with
the requirements of DTC. The decision of Merger Sub (or the Exchange Agent) in
such matters shall be conclusive and binding on the holders of Company Common
Stock.

  (viii) ELECTION DEADLINE. An Election must be received by the Exchange Agent
by the close of business on the last business day prior to the Effective Time
(such time hereinafter referred to as the "ELECTION DEADLINE") in order to be
effective. Any holder of Company Common Stock who has made an Election may at
any time prior to the Election Deadline change such holder's election by
submitting a revised Form of Election, properly completed and signed, that is
received by the Exchange Agent prior to the Election Deadline or, in the case of
shares of Company Common Stock held in book-entry form, by causing there to be
transmitted and received by the Exchange Agent prior to the Election Deadline a
properly transmitted "Request Message" through ATOP. Any holder of Company
Common Stock may at any time prior to the Election Deadline revoke its election
and withdraw its certificates representing shares of Company Common Stock
deposited with the Exchange Agent by written notice to the Exchange Agent
received prior to the Election Deadline or, in the case of shares of Company
Common Stock held in book-entry form, withdraw its shares of Company Common
Stock transferred to the Exchange Agent by a properly transmitted "Request
Message" through ATOP prior to the Election Deadline specifying the name and
number of the account at DTC to be credited. As soon as practicable after the
Election Deadline, the Exchange Agent shall determine the number of Cash
Electing Shares, Stock Electing Shares and Non-Electing Shares, and shall notify
Merger Sub of its determination. Promptly after such notification, Parent and
Merger Sub shall issue a press release announcing in reasonable detail the
allocation of the Merger Consideration.

    (ix) DEEMED NON-ELECTION. For the purposes hereof, the shares of a holder of
Company Common Stock who does not submit an Election prior to the Election
Deadline shall be deemed to be Non-Electing Shares. If Merger Sub or the
Exchange Agent shall determine that any purported election was not properly
made, such purported election shall be deemed to be of no force and effect, and
the shares with respect to which such purported election was made shall, for
purposes hereof, be deemed to be Non-Electing Shares. Neither Merger Sub nor the
Exchange Agent shall have any obligation to inform any holder of Company Common
Stock of any defect in the making of an election.

                                      A-5
<PAGE>
    (x) RETURN OF COMPANY COMMON STOCK. In the event that this Agreement is
terminated without the Merger having been consummated, Merger Sub shall instruct
the Exchange Agent to return all shares of Company Common Stock submitted or
transferred to the Exchange Agent pursuant to Section 1.06(a)(vii).

    (b) CANCELLATION Each Share held in the treasury of the Company and each
Share owned by Parent, Merger Sub or any direct or indirect, wholly-owned
subsidiary of the Company or Parent immediately prior to the Effective Time
shall, by virtue of the Merger and without any action on the part of the holder
thereof, cease to be outstanding, be canceled and retired without payment of any
consideration therefor and cease to exist.

    (c) COMPANY/EQUITY AWARDS.

        (i) STOCK OPTIONS. Each option outstanding at the Effective Time to
    purchase shares of Company Common Stock (a "STOCK OPTION") granted under (A)
    the Company's Executive Long Term Incentive Plan, (B) the Company's Amended
    and Restated 1987 Directors Stock Option Plan, (C) the Company's Amended and
    Restated 1990 Incentive Plan (the "1990 PLAN"), (D) the Company's 1996
    Directors Stock Option Plan, (E) the Company's Bonus Deferral Plan (the
    "BONUS DEFERRAL PLAN"), (F) the 1981 Stock Option Plan or (G) any other
    written or otherwise binding stock option plan or agreement of the Company
    except the Company's 1984 Employee Stock Purchase Plan, the 1985 Employee
    Stock Purchase Plan and the Amended and Restated Raychem Corporation Limited
    Employee Stock Purchase Plan (the "STOCK PURCHASE PLANS") (collectively, the
    "COMPANY STOCK OPTION PLANS"), shall constitute an option (an "ADJUSTED
    OPTION") to acquire, on the same terms and conditions MUTATIS MUTANDIS as
    were applicable to such Stock Option prior to the Effective Time (but taking
    account of the Merger), the number of Parent Common Shares (rounded down to
    a whole Parent Common Share) determined by multiplying (x) the number of
    shares of Company Common Stock subject to such Stock Options immediately
    prior to the Effective Time by (y) 0.4140, at a price per share (rounded up
    to a whole cent) equal to (u) the per share exercise price for Company
    Common Stock otherwise purchasable pursuant to such Stock Option divided by
    (v) 0.4140. The other terms of each such Stock Option, and the Company Stock
    Option Plans under which they were issued, shall continue to apply in
    accordance with their terms, including, to the extent provided therein or
    under the Company's Key Employee Retention and Severance Plan, the
    acceleration of vesting of such Stock Options in connection with the
    transactions contemplated hereby or upon the termination of employment of a
    holder of an Adjusted Option. As soon as practicable after the Effective
    Time, Merger Sub shall cause to be delivered to each holder of an
    outstanding Stock Option an appropriate notice setting forth such holder's
    rights pursuant thereto, and stating that such Stock Option shall continue
    in effect on the same terms and conditions (subject to the adjustments as a
    result of the Merger described in this Section 1.06(c)). Parent shall comply
    with the terms of all such Adjusted Options and ensure, to the extent
    required by, and subject to the provisions of, the Company Stock Option
    Plans, that Adjusted Options which qualified as incentive stock options
    under Section 422(b) of the Code ("ISOS") prior to the Effective Time
    continue to qualify as ISOs after the Effective Time to the extent
    permissible under governing law. Nothing in this paragraph is intended to or
    shall amend or modify the terms of any Stock Option, including any provision
    for its expiration, cancellation or forfeiture in a transaction such as the
    Merger.

        (ii) RESTRICTED SHARES. As of the Effective Time, each holder of an
    outstanding share of restricted stock (each, a "RESTRICTED SHARE") under any
    Company stock incentive plan, the terms of which do not provide for its
    vesting in a transaction such as the Merger, shall receive 0.4140 of a
    Parent Common Share in exchange for such Restricted Share. Any such Parent
    Common Share so received shall be subject to all the terms and conditions of
    the plans and agreements under which the Restricted Share was issued and the
    Company's Key Employee Retention and Severance Plan but only to the extent
    such plan specifically modifies one or more terms of such Restricted Share,

                                      A-6
<PAGE>
    MUTATIS MUTANDIS, including acceleration of vesting of such Restricted Share
    in connection with the transactions contemplated hereby or upon the
    termination of employment of any holder of a Restricted Share. The terms of
    Section 1.06(f) shall apply to the Parent Common Shares issued in exchange
    for such Restricted Shares. Restricted Shares that vest upon consummation of
    the Merger shall be exchanged in the Merger as provided in Section 1.06(a).

       (iii) AMENDMENT, MODIFICATION OR TERMINATION. Nothing in this Section
    1.06(c) is intended to or shall be construed as limiting in any respect
    Parent's or Merger Sub's right to amend, modify or terminate after the
    Effective Time any equity-based plan of the Company to the extent Parent or
    Merger Sub is otherwise permitted to do so.

        (iv) REGISTRATION. Parent shall reserve for issuance a sufficient number
    of Parent Common Shares for delivery upon exercise of Adjusted Options in
    accordance with this Section 1.06(c). Either on or as soon as practicable
    following the Effective Time, Parent will register the Parent Common Shares
    subject to the Adjusted Options under the United States Securities Act of
    1933, as amended, and the rules and regulations of the United States
    Securities and Exchange Commission ("SEC") thereunder (the "SECURITIES ACT")
    pursuant to a registration statement on Form S-4 or Form S-8 (or any
    successor or other appropriate form) to the extent such registration is
    required under the Securities Act, and to use at least such efforts as are
    applied to Parent's other stock options generally to cause the effectiveness
    of such registration statement or registration statements (and the current
    status of the prospectus or prospectuses contained therein) to be maintained
    for so long as the Adjusted Options remain outstanding (subject to
    interruptions of such effectiveness or current status as may be reasonably
    required from time to time, and are applicable to registration statements of
    Parent with respect to its option plans generally, because of developments
    affecting Parent or otherwise).

    (d) CAPITAL STOCK OF MERGER SUB. Each share of common stock, $0.01 par value
per share, of Merger Sub issued and outstanding immediately prior to the
Effective Time shall constitute one validly issued, fully paid and nonassessable
share of common stock, $0.01 par value, of the Surviving Corporation.

    (e) ADJUSTMENTS TO EXCHANGE RATIO. The Cash Amount and the Share Ratio shall
be appropriately adjusted to reflect fully the effect of any stock split,
reverse split or stock dividend (including any dividend or distribution of
securities convertible into Parent Common Shares or Company Common Stock); any
distribution, exercise or exchange of Rights (as defined in Section 5.13) or
such Rights becoming exercisable; or any reorganization, recapitalization, split
up, combination or exchange of shares, or other like event with respect to
Parent Common Shares (in the case of the Share Ratio) or Company Common Stock
(in the case of both the Share Ratio and the Cash Amount), occurring after the
date hereof and prior to the Effective Time.

    (f) FRACTIONAL SHARES. No certificates or scrip representing less than one
Parent Common Share shall be issued in exchange for Shares upon the surrender
for exchange of a certificate which immediately prior to the Effective Time
represented outstanding Shares (the "CERTIFICATES") or pursuant to any
book-entry transfer. In lieu of any such fractional share, each holder of Shares
who would otherwise have been entitled to a fraction of a Parent Common Share
shall be paid upon such surrender cash (without interest) in an amount equal to
such fraction multiplied by the Average Share Price.

                                      A-7
<PAGE>
    Section 1.07.  EXCHANGE OF SHARES.  (a) EXCHANGE AGENT. At or prior to the
Effective Time, and, to the extent required, from time to time thereafter,
Merger Sub shall cause to be supplied to or for such bank or trust company as
shall be designated by Merger Sub and shall be reasonably acceptable to the
Company (the "EXCHANGE AGENT"), in trust for the benefit of the holders of
Company Common Stock (other than Dissenting Shares), for exchange in accordance
with this Section 1.07 through the Exchange Agent, (i) certificates evidencing
the Parent Common Shares issuable pursuant to Section 1.06(a), (ii) the cash
payable pursuant to Section 1.06(a) and (iii) cash payable in lieu of fractional
shares pursuant to Section 1.06(f) (such certificates for Parent Common Shares
and cash being referred to as the "EXCHANGE FUND").

    (b) EXCHANGE PROCEDURES. As soon as reasonably practicable after the
Effective Time, Merger Sub will cause the Exchange Agent to mail to each holder
of record of Certificates who has not submitted (or who has submitted and
withdrawn) such holders' Certificates to the Exchange Agent in accordance with
Section 1.06(a)(vii) (other than Certificates representing Dissenting Shares)
(i) a letter of transmittal (which shall specify that delivery shall be
effected, and risk of loss and title to the Certificates shall pass, only upon
proper delivery of the Certificates to the Exchange Agent and shall be in such
form and have such other provisions as Merger Sub may reasonably specify) and
(ii) instructions to effect the surrender of the Certificates in exchange for
the certificates evidencing Parent Common Shares and cash. A holder that has
submitted and not withdrawn Shares as provided in Section 1.06(a)(vii) or that
surrenders Certificates for cancellation to the Exchange Agent, together with a
duly executed letter of transmittal, and other required documents as provided in
this Section 1.07(b), shall be entitled to receive in exchange therefor solely
(A) certificates evidencing that number of whole Parent Common Shares which such
holder has the right to receive in accordance with Section 1.06(a) in respect
thereof and/or (B) the cash which such holder has the right to receive in
accordance with Section 1.06(a) in respect thereof, together with any cash in
respect of fractional shares as provided in Section 1.06(f) (such Parent Common
Shares and cash being referred to, collectively, as the "MERGER CONSIDERATION"),
except that Shares held at the Effective Time in book-entry form shall be
exchanged for Merger Consideration in accordance with the customary procedures
of DTC. The holder of Shares upon their exchange, in whole or in part, for
Parent Common Shares shall also receive any dividends or other distributions
declared or made with a record date after the Effective Time with respect to
such Parent Common Shares. Certificates surrendered pursuant to this Section
1.07(b) or Section 1.06(a)(vii) shall forthwith be canceled following the
Effective Time. In the event of a transfer of ownership of Shares which is not
registered in the transfer records of the Company as of the Effective Time, the
Merger Consideration, dividends or distributions may be issued and paid in
accordance with this Article I to a transferee if the Certificate evidencing
such Shares is presented to the Exchange Agent, accompanied by all documents
required to evidence and effect such transfer pursuant to this Section 1.07(b)
and by evidence that any applicable stock transfer taxes have been paid. Until
so surrendered, each outstanding Certificate that, prior to the Effective Time,
represented shares of Company Common Stock will be deemed from and after the
Effective Time, for all corporate purposes, other than the payment of dividends
or other distributions, to represent only the right to receive upon such
surrender the applicable Merger Consideration with respect to the shares of
Company Common Stock formerly represented thereby.

    (c) DISTRIBUTIONS WITH RESPECT TO UNEXCHANGED SHARES. No dividends or other
distributions declared or made after the Effective Time with respect to Parent
Common Shares with a record date after the Effective Time shall be paid to the
holder of any unsurrendered Certificate with respect to the Parent Common Shares
entitled to be received therefor until the holder of such Certificate shall
surrender such Certificate in accordance with the provisions of Section 1.07(b).
Subject to applicable law, following surrender of any such Certificate, there
shall be paid to the record holder of the certificates representing whole Parent
Common Shares issued in exchange therefor, without interest, at the time of such
surrender, the amount of dividends or other distributions with a record date
after the Effective Time theretofore paid with respect to such whole Parent
Common Shares.

                                      A-8
<PAGE>
    (d) TRANSFERS OF OWNERSHIP. If any Merger Consideration is to be issued and
paid to a person other than the person in whose name the Certificate surrendered
in exchange therefor is registered, it will be a condition of the payment
thereof that the Certificate so surrendered will be properly endorsed and
otherwise in proper form for transfer and that the person requesting such
exchange will have paid to Merger Sub or any agent designated by it any transfer
or other taxes required by reason of the issuance of a certificate for Parent
Common Shares in any name other than that of the registered holder, or payment
of cash to any person other than the registered holder, of the Certificate
surrendered, or establish to the satisfaction of Merger Sub or any agent
designated by it that such tax has been paid or is not payable.

    (e) ESCHEAT. Neither Parent, Merger Sub nor the Company nor any of their
respective affiliates shall be liable to any holder of Company Common Stock for
any Merger Consideration delivered to a public official pursuant to any
applicable abandoned property, escheat or similar law.

    (f) WITHHOLDING RIGHTS. The Exchange Agent shall be entitled to deduct and
withhold from the Merger Consideration otherwise issuable or payable pursuant to
this Agreement to any holder of Company Common Stock, and from any cash
dividends or other distributions that the holder is entitled to receive under
Section 1.07(b) or (c), such amounts as the Exchange Agent is required to deduct
and withhold with respect to the making of such payment under the Code, or any
provision of state, local or non-United States tax law. To the extent that
amounts are so withheld by the Exchange Agent, such portion of the Merger
Consideration and other such amounts payable under Section 1.07(b) or (c) that
are withheld shall be treated for all purposes of this Agreement as having been
received by the holder of the Shares in respect of which such deduction and
withholding was made by the Exchange Agent.

    (g) TERMINATION OF EXCHANGE FUND. Any portion of the Exchange Fund which
remains undistributed to the holders of the Certificates one year after the
Effective Time shall be delivered to Merger Sub, upon demand, and any holders of
the Certificates who have not theretofore complied with this Section 1.07 shall
thereafter look only to Merger Sub for payment of their claim for Merger
Consideration and any dividends or distributions with respect to Parent Common
Shares.

    Section 1.08.  STOCK TRANSFER BOOKS.  At the Effective Time, the stock
transfer books of the Company shall be closed, and there shall be no further
registration of transfers of the Company Common Stock thereafter on the records
of the Company.

    Section 1.09.  NO FURTHER OWNERSHIP RIGHTS IN COMPANY COMMON STOCK.  The
Merger Consideration delivered upon the surrender for exchange of Shares in
accordance with the terms hereof shall be deemed to have been issued in full
satisfaction of all rights pertaining to such Shares, and there shall be no
further registration of transfers on the records of the Surviving Corporation of
Shares which were outstanding immediately prior to the Effective Time. If, after
the Effective Time, Certificates are presented to the Surviving Corporation, the
Parent or the Exchange Agent for any reason, they shall be canceled and
exchanged as provided in this Article I.

    Section 1.10.  LOST, STOLEN OR DESTROYED CERTIFICATES.  In the event any
Certificates shall have been lost, stolen or destroyed, the Exchange Agent shall
pay and/or issue in exchange for such lost, stolen or destroyed Certificates,
upon the making of an affidavit of that fact by the holder thereof, such cash
and/or Parent Common Shares as may be required pursuant to Section 1.06(a);
PROVIDED, HOWEVER, that Merger Sub may, in its discretion and as a condition
precedent to the issuance thereof, require the owner of such lost, stolen or
destroyed Certificates 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 Exchange Agent with respect to the Certificates alleged to
have been lost, stolen or destroyed.

    Section 1.11.  TAX CONSEQUENCES.  Subject to Section 6.04, it is intended by
the parties hereto that the Merger shall constitute a reorganization within the
meaning of Section 368 of the Code and the regulations promulgated thereunder.
The parties hereto hereby adopt this Agreement as a "plan of

                                      A-9
<PAGE>
reorganization" within the meaning of Sections 1.368-2(g) and 1.368-3(a) of the
United States Treasury Regulations.

    Section 1.12.  TAKING OF NECESSARY ACTION; FURTHER ACTION.  Each of Parent,
Merger Sub and the Company will take all such reasonable and lawful actions as
may be necessary or appropriate in order to effectuate the Merger and the other
transactions contemplated by this Agreement in accordance with this Agreement as
promptly as possible. If, at any time after the Effective Time, any such further
action is necessary or desirable to carry out the purposes of this Agreement and
to vest the Surviving Corporation with full right, title and possession to all
assets, property, rights, privileges, powers and franchises of the Company and
Merger Sub, the officers and directors of the Company and Merger Sub immediately
prior to the Effective Time are fully authorized in the name of their respective
corporations or otherwise to take, and will take, all such lawful and necessary
action.

    Section 1.13.  DISSENTING SHARES.  Notwithstanding any other provisions of
this Agreement to the contrary, shares of Company Common Stock that are issued
and outstanding immediately prior to the Effective Time and which are held by
stockholders who shall have not voted in favor of the Merger or consented
thereto in writing and who shall have demanded properly in writing appraisal for
such Shares in accordance with Section 262 of the DGCL (collectively, the
"DISSENTING SHARES") shall not be converted into or represent the right to
receive the Merger Consideration. Such stockholders shall be entitled to receive
payment of the appraised value of such shares of Company Common Stock held by
them in accordance with the provisions of such Section 262, except that all
Dissenting Shares held by stockholders who shall have failed to perfect or who
effectively shall have withdrawn or lost their rights to appraisal of such
shares of Company Common Stock under such Section 262 shall thereupon be deemed
to have been converted into and to have become exchangeable, as of the Effective
Time, for the right to receive, without any interest thereon, cash, Parent
Common Shares or a combination of cash and Parent Common Shares, in the sole
discretion of Merger Sub, such that (x) the sum of (I) such cash and (II) the
number of such Parent Common Shares multiplied by the Average Share Price equals
(y) (I) the number of shares of Company Common Stock so converted multiplied
(II) by the Closing Per Share Amount, together with any dividends or other
distributions to which such stockholders are entitled pursuant to Section
1.07(c), except that cash will be paid in lieu of any fractional Parent Common
Shares pursuant to Section 1.06(f).

    Section 1.14.  MATERIAL ADVERSE EFFECT.  When used in connection with the
Company or any of its subsidiaries or Parent or any of its subsidiaries, as the
case may be, the term "MATERIAL ADVERSE EFFECT" means any change, effect or
circumstance that is or would reasonably be expected to be materially adverse to
the business, assets (including intangible assets), financial condition or
results of operations of the Company and its subsidiaries or Parent and its
subsidiaries, as the case may be, in each case taken as a whole; PROVIDED,
HOWEVER, that effects of changes that result from (A) any changes in economic,
regulatory or political conditions generally, (B) the United States securities
markets, (C) this Agreement or the transactions contemplated by this Agreement
or the announcement hereof or (D) with respect to the Company, any changes
affecting the construction, electronic components, telecommunications or energy
infrastructure industries generally, shall be excluded from the definition of
"Material Adverse Effect" and from any determination as to whether a Material
Adverse Effect has occurred or may occur.

                                   ARTICLE II

                 REPRESENTATIONS AND WARRANTIES OF THE COMPANY

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

    Section 2.01.  ORGANIZATION AND QUALIFICATION; SUBSIDIARIES.  Each of the
Company and its subsidiaries is an entity duly organized, validly existing and
in good standing under the laws of the jurisdiction of its incorporation and has
the requisite corporate or other power and authority necessary to own, lease and
operate the properties it purports to own, operate or lease and to carry on its
business as it is now being conducted, except where the failure to be so
organized, existing and in good standing or to have such power or authority
would not reasonably be expected to have a Material Adverse Effect. Each of the
Company and its subsidiaries is duly qualified or licensed as a foreign
corporation to do business, and is in good standing, in each jurisdiction where
the character of its properties owned, leased or operated by it or the nature of
its activities makes such qualification or licensing necessary, except for such
failures to be so duly qualified or licensed and in good standing that would not
reasonably be expected to have a Material Adverse Effect. A true and complete
list of all of the Company's "significant" subsidiaries, as defined in
Regulation S-X, is included as an exhibit to the Company's 1998 Annual Report on
Form 10-K (the "COMPANY SIGNIFICANT SUBSIDIARIES"). The Company has furnished to
Parent a list of all subsidiaries of the Company together with the jurisdiction
of incorporation or organization of each such subsidiary and the percentage of
each such subsidiary's outstanding capital stock owned by the Company or another
subsidiary of the Company in Section 2.01 of the written disclosure schedule
previously delivered by the Company to Parent (the "COMPANY DISCLOSURE
SCHEDULE"). Except as set forth in Section 2.01 of the Company Disclosure
Schedule or the Company SEC Reports (as defined in Section 2.07 below), neither
the Company nor any of its subsidiaries directly or indirectly owns any equity
or similar interest in, or any interest convertible into or exchangeable or
exercisable for any equity or similar interest in, any corporation, partnership,
joint venture or other business association or entity (other than its
wholly-owned subsidiaries), with respect to which interest the Company or a
subsidiary has invested (and currently owns) or is required to invest $2,000,000
or more, excluding securities in any publicly-traded company held for investment
by the Company and comprising less than five percent of the outstanding stock of
such company.

    Section 2.02.  CERTIFICATE OF INCORPORATION AND BYLAWS.  The Company has
heretofore made available to Parent and Merger Sub complete and correct copies
of (i) its Amended and Restated Certificate of Incorporation and Amended and
Restated Bylaws, each as amended to date (the "COMPANY'S CHARTER DOCUMENTS"),
and (ii) the Certificate of Incorporation and Bylaws (or equivalent
organizational documents) (with respect to any subsidiary of the Company, the
"SUBSIDIARY DOCUMENTS") of each of its subsidiaries that account for more than
10% of the assets or sales of the Company on a consolidated basis. Within 30
days of the date of this Agreement, the Company will deliver to Parent the
Subsidiary Documents of each other active subsidiary of the Company. All such
Company Charter Documents and Subsidiary Documents are in full force and effect.
Neither the Company nor any of its subsidiaries is in violation of any of the
provisions of its Certificate of Incorporation or Bylaws or equivalent
organizational documents, except for immaterial violations of the documents
which do not and are not reasonably likely to materially interfere with the
operations of such entity.

    Section 2.03.  CAPITALIZATION.  The authorized capital stock of the Company
consists of 150,000,000 shares of Company Common Stock and 15,000,000 shares of
the Company's Preferred Stock (the "COMPANY PREFERRED STOCK"), par value $1.00
per share, of which 150,000 shares have been designated as Series RP Preferred
Stock. As of May 17, 1999, (i) 77,585,116 shares of Company Common Stock were
issued and outstanding, all of which are validly issued, fully paid and
nonassessable, (ii) 12,778,879 shares were held in treasury, (iii) no shares of
Company Preferred Stock were outstanding or held in treasury, (iv) no shares of
Company Common Stock or Company Preferred Stock were held by subsidiaries of the
Company, (v) 10,966,914 shares of Company Common Stock were issuable upon the

                                      A-11
<PAGE>
exercise of outstanding options granted under the Company's Stock Option Plans
and (vi) 2,311,000 shares of Company Common Stock were subject to future
issuance pursuant to the Stock Purchase Plans. Except as set forth in Section
2.03 of the Company Disclosure Schedule, no change in such capitalization has
occurred as of the date hereof, except for changes resulting from the exercise
of Stock Options and for issuances in accordance with the terms of the Stock
Purchase Plans. Except as set forth in Section 2.01, this Section 2.03 or
Section 2.11, Section 2.03 or Section 2.11 of the Company Disclosure Schedule or
for rights granted pursuant to the Company's Rights Agreement (as defined in
Section 2.24), there are no options, warrants or other rights, agreements,
arrangements or commitments of any character binding on the Company or any of
its subsidiaries relating to the issued or unissued capital stock of the Company
or any of its subsidiaries or obligating the Company or any of its subsidiaries
to issue or sell any shares of capital stock of, or other equity interests in,
the Company or any of its subsidiaries. All shares of Company Common Stock
subject to issuance as aforesaid, upon issuance on the terms and conditions
specified in the instruments pursuant to which they are issuable, shall be duly
authorized, validly issued, fully-paid and nonassessable. Except as disclosed in
Section 2.03 of the Company Disclosure Schedule or the Company SEC Reports,
there are no obligations, contingent or otherwise, of the Company or any of its
subsidiaries to repurchase, redeem or otherwise acquire any shares of Company
Common Stock or the capital stock of any subsidiary. Except as disclosed in
Section 2.03 of the Company Disclosure Schedule or the Company SEC Reports,
there are no obligations, contingent or otherwise, of the Company or any of its
subsidiaries to provide funds to or make any investment (in the form of a loan,
capital contribution or otherwise) in any such subsidiary or any other entity
other than guarantees of bank obligations of subsidiaries entered into in the
ordinary course of business. Except as set forth in Section 2.01 or 2.03 of the
Company Disclosure Schedule, all of the outstanding shares of capital stock
(other than directors' qualifying shares) of each of the Company's subsidiaries
are duly authorized, validly issued, fully-paid and nonassessable, and all such
shares (other than directors' qualifying shares and a DE MINIMIS number of
shares owned by employees of such subsidiaries) are owned by the Company or
another subsidiary free and clear of all security interests, liens, claims,
pledges, agreements, limitations in the Company's voting rights, charges or
other encumbrances of any nature whatsoever.

    Section 2.04.  AUTHORITY RELATIVE TO THIS AGREEMENT.  The Company has all
necessary corporate power and authority to execute and deliver this Agreement
and to perform its obligations hereunder and to consummate the transactions
contemplated hereby. The execution and delivery of this Agreement by the Company

applicable to the Company or any of its subsidiaries or by which its or any of

both would become a default), or impair the Company's or any of its
subsidiaries' rights or alter the rights or obligations of any third party
under, or give to others any rights of termination, amendment, acceleration or
cancellation of, or result in the creation of a lien or encumbrance on

which the Company or any of its subsidiaries or its or any of their respective
properties is bound or affected, except, in the case of clause (ii) or (iii),
for any such conflicts, violations, breaches, defaults or other occurrences that
would not reasonably be expected, individually or in the aggregate, to have a
Material Adverse Effect.

where the failure to obtain such consents, approvals, authorizations or permits,
or to make such filings or notifications, would not prevent or materially delay
consummation of the Merger, or

                                      A-13
<PAGE>
otherwise prevent or materially delay the Company from performing its material
obligations under this Agreement, or would not otherwise reasonably be expected,
individually or in the aggregate, to have a Material Adverse Effect, or (iii) as
to which any necessary consents, approvals, authorizations, permits, filings or
notifications have heretofore been obtained or filed, as the case may be, by the
Company.

    Section 2.06.  COMPLIANCE; PERMITS.  (a) Except as disclosed in Section

operation of the business of the Company and its subsidiaries, taken as a whole,
as it is now being conducted (collectively, the "COMPANY PERMITS"), except where
the failure to hold such Company Permits would not reasonably be expected,
individually or in the aggregate, to have a Material Adverse Effect.

    The Company and its subsidiaries are in compliance with the terms of the
Company Permits, except as described in the Company SEC Reports or where the
failure to so comply would not reasonably be expected, individually or in the
aggregate, to have a Material Adverse Effect.

    Section 2.07.  SEC FILINGS; FINANCIAL STATEMENTS.  (a) The Company has filed

Schedule, the Company SEC Reports (i) were prepared in all material respects in
accordance with the requirements of the Securities Act or the Exchange Act, as

superseded by a filing prior to the date of this Agreement, then on the date of
such filing) contain any untrue statement of a material fact or omit to state a
material fact required to be stated therein or necessary in order to make the
statements therein, in the light of the circumstances under which they were

Company and its subsidiaries as at the respective dates thereof and the

be material in amount.

<PAGE>
individually or in the aggregate, to have a Material Adverse Effect; (iv) any

for prohibited transactions under ERISA or Section 4975 of the Code; (iv) to the
Company's knowledge, no fiduciary of any Company Employee Plan has breached any

substantially in accordance with their terms and have operated in compliance in
all material respects with the requirements of applicable law (including, but

such event for

                                      A-16
<PAGE>
which the 30-day notice requirement has been waived under the regulations to
Section 4043 of ERISA) has occurred for which there is any material outstanding
liability to the Company or any Company ERISA Affiliate nor would the
consummation of the transactions contemplated hereby (including the execution of

has not been waived; (ix) none among the Company, any Company ERISA Affiliate or
any subsidiary thereof has incurred or reasonably expects to incur any material
liability under Title IV of ERISA including, without limitation, with respect to

that would materially adversely affect the funding status of such plans; (iv)
all applicable premiums required to be paid to the PBGC with respect to the

maintained in good standing with applicable regulatory authorities. Except as
set forth on Section 2.11(h) of the Company Disclosure Schedule, each Non-U.S.
Company Plan which is required by contract or under applicable local law to be
funded has been funded at least to the extent so required; if and to the extent

                                  ARTICLE III
            REPRESENTATIONS AND WARRANTIES OF PARENT AND MERGER SUB

    Parent and Merger Sub hereby, jointly and severally, represent and warrant
to the Company as follows:

    Section 3.01.  ORGANIZATION AND QUALIFICATION; SUBSIDIARIES.  Each of Parent
and its subsidiaries is an entity duly organized and validly existing under the
laws of the jurisdiction of its incorporation and has the requisite corporate or
other power and authority necessary to own, lease and operate the properties it
purports to own, operate or lease and to carry on its business as it is now
being conducted, except where the failure to be so organized and existing or to
have such power or authority would not reasonably be expected to have a Material
Adverse Effect. Each of Parent and its subsidiaries is duly qualified or
licensed as a foreign corporation to do business, and is in good standing, in
each jurisdiction where the character of its properties owned, leased or
operated by it or the nature of its activities makes such qualification or
licensing necessary, except for such failures to be so duly qualified or
licensed and in good standing that would not reasonably be expected to have a
Material Adverse Effect. A true and complete list of all of Parent's
subsidiaries, together with the jurisdiction of incorporation or organization of
each subsidiary and the percentage of each subsidiary's outstanding capital
stock owned by Parent or another subsidiary of Parent, is set forth in Section
3.01 of the written disclosure schedule previously delivered by Parent to the
Company (the "PARENT DISCLOSURE SCHEDULE"). Except as set forth in Section 3.01
of the Parent Disclosure Schedule or the Parent SEC Reports (as defined in
Section 3.07 below), Parent does not directly or indirectly own any equity or
similar interest in, or any interest convertible into or exchangeable or
exercisable for, any equity or similar interest in, any corporation,
partnership, joint venture or other business association or entity (other than
its wholly-owned subsidiaries), with respect to which Parent has invested and
currently owns or is required to invest $10,000,000 or more, excluding
securities in any publicly traded company held for investment by Parent and
comprising less than five percent of the outstanding capital stock of such
company.

    Section 3.02.  MEMORANDUM OF ASSOCIATION AND BYE-LAWS.  Parent has
heretofore made available to the Company a complete and correct copy of Parent's
Memorandum of Association and Bye-Laws, as amended to date (the "PARENT CHARTER
DOCUMENTS"). Such Parent Charter Documents are in full

                                      A-24
<PAGE>
force and effect. Neither Parent nor Merger Sub is in violation of any of the
provisions of its Memorandum of Association (or Articles of Incorporation) or
bye-laws (or by-laws).

    Section 3.03.  CAPITALIZATION.  (a) The authorized capital stock of Parent
consists of 2,500,000,000 Parent Common Shares and 125,000,000 Preference
Shares, $1.00 par value per share ("PARENT PREFERRED SHARES"). (i) As of April
2, 1999, (I) 818,453,964 Parent Common Shares were issued and outstanding, all

Preferred Shares were outstanding and (III) no more than 10,000,000 Parent
Common Shares and no Parent Preferred Shares were held by subsidiaries of
Parent; (ii) as of March 31, 1999, warrants to purchase 98,966 Parent Common
Shares were outstanding; and (iii) as of March 31, 1999, approximately
60,607,058 Common Shares were reserved for issuance upon exercise of stock
options issued under Parent's stock option plans. No material change in such
capitalization has occurred since such dates, respectively, other than as a
result of the exercise of options or warrants outstanding as of such dates.
Except as set forth in Section 3.03 of the Parent Disclosure Schedule or the
Parent SEC Reports or as contemplated by this Agreement, there are no options,
warrants or other rights, agreements, arrangements or commitments of any
character binding on Parent or any of its subsidiaries relating to the issued or
unissued capital stock of Parent or any of its subsidiaries or obligating Parent
or any of its subsidiaries to issue or sell any shares of capital stock of, or
other equity interests in, Parent or any of its subsidiaries. Except as set
forth in Section 3.01 or 3.03 of the Parent Disclosure Schedule, all of the
outstanding shares of capital stock (other than directors' qualifying shares) of
each of Parent's subsidiaries is duly authorized, validly issued, fully paid and
nonassessable, and all such shares (other than directors' qualifying shares and
a DE MINIMIS number of shares owned by employees of such subsidiaries) are owned
by Parent or another subsidiary free and clear of all security interests, liens,
claims, pledges, agreements, limitations in Parent's voting rights, charges or
other encumbrances of any nature whatsoever. The authorized capital stock of
Merger Sub consists of 10,000 shares of common stock, par value $0.01 per share,
all of which are duly authorized, and of which 6,000 shares are issued. All such
issued shares are validly issued, fully paid and non-assessable and free of any
preemptive rights in respect thereof and all of the outstanding shares of which
are owned by Parent.

Merger Sub has all necessary corporate power and authority to execute and
deliver this Agreement, as applicable, and to perform its obligations hereunder
and to consummate the transactions contemplated hereby. The execution and
delivery of this Agreement by Parent and Merger Sub and the consummation by
Parent and Merger Sub of the transactions contemplated hereby have been duly and
validly authorized by all necessary corporate action on the part of Parent and
Merger Sub, and no other corporate proceedings on the part of Parent or Merger
Sub are necessary to authorize this Agreement or to consummate the transactions
so contemplated. The Board of Directors of Parent has determined that it is
advisable and in the best interests of Parent's shareholders for Parent to enter
into this Agreement, and for Parent to consummate the Merger upon the terms and
subject to the conditions of this Agreement. This Agreement has been duly and
validly executed and delivered by Parent and Merger Sub, and, assuming due
authorization, execution and delivery by the Company, constitutes the legal,
valid and binding obligation of Parent and Merger Sub.

Schedule, the execution and delivery of this Agreement by Parent and Merger Sub
do not, and the performance of this Agreement by Parent and Merger Sub will not,

Incorporation) or bye-laws (or by-laws) of Parent or Merger Sub, (ii) conflict
with or violate any law, rule, regulation, order, judgment or decree applicable
to Parent or any of its subsidiaries or by which its or their respective

Agreement and would not otherwise be reasonably expected, individually or in the
aggregate, to have a Material Adverse Effect or (iii) as to which any necessary

established and maintained substantially in accordance with their terms and have
operated in compliance in all material respects with the requirements of
applicable law; (iv) each Parent Employee Plan which is intended to be qualified
under Section 401(a) of the Code is the subject of a favorable determination
letter from the IRS, and, to Parent's knowledge, nothing has occurred which may

required to be made with respect to any Parent Employee Plan (whether pursuant
to the terms of such plan, Section 412 of the Code, any collective bargaining
agreement, or otherwise) have been made on or before their due dates (including
any extensions thereof); (vi) with respect to each Parent Employee Plan, no
"reportable event" within the meaning of Section 4043 of ERISA (excluding any
such event for which the 30-day notice requirement has been waived under the
regulations to Section 4043 of ERISA) has occurred for which there is any
material outstanding liability to Parent or any Parent ERISA Affiliate nor would
the consummation of the transaction contemplated hereby (including the execution
of this Agreement) constitute a reportable event for which the 30-day
requirement has not been waived; and (vii) neither Parent nor any Parent ERISA
Affiliate has incurred or reasonably expects to incur any material liability
under Title IV of ERISA including, without limitation, with respect to an event
described in Section 4062, 4063 or 4041 of ERISA (other than liability for
premium payments to the PBGC arising in the ordinary course).

    (c) Except as set forth in Section 3.11(c) of the Parent Disclosure

value of the benefit liabilities (within the meaning of Section 4041 of ERISA)
of each Parent Defined Benefit Plan, determined on an ongoing basis using the
actuarial assumptions used for funding purposes in the most recent actuarial
report prepared by each such plan's actuary with respect to that plan's most
recently completed fiscal year, does not exceed by more than $10,000,000 the
value of that Parent Defined Benefit Plan's assets and, to the knowledge of
Parent, nothing has occurred since the end of the most recently completed fiscal
year that would adversely affect the funding status of such plans; (iv) all
applicable premiums required to be paid to the PBGC with respect to the Parent
Defined Benefit Plans have been paid; and (v) no facts or

                                      A-28
<PAGE>
circumstances exist with respect to any Parent Defined Benefit Plan which would
give rise to a lien on the assets of Parent under Section 4068 of ERISA or
otherwise.

    (d) Each Parent Employee Plan covering non-U.S. employees (a "NON-U.S.
PARENT PLAN") has been maintained in substantial compliance with its terms and

be registered with the SEC shall not, at the time the Registration Statement
(including any amendments or supplements thereto) is declared effective by the
SEC, contain any untrue statement of a material fact or omit to state any
material fact necessary in order to make the statements included therein, in

statements therein not false or misleading, or omit to state any material fact
necessary to correct any statement in any earlier communication with respect to
the solicitation of proxies for the Company Stockholders Meeting which has

relating to Parent, Merger Sub or any of their respective affiliates, officers
or directors should be discovered by Parent or Merger Sub which should be set
forth in an amendment to the Registration Statement or a supplement to the Proxy
Statement/Prospectus, Parent or Merger Sub will promptly inform the Company. The
Registration Statement and Proxy Statement/Prospectus shall comply in all
material respects with the requirements of the Securities Act and the Exchange
Act. Notwithstanding the foregoing, Parent and Merger Sub make no representation
or warranty with respect to any information supplied by the Company which is

existing material default or event of default (or event which with notice or

default or event of default, would not reasonably be expected, individually or

date of this Agreement or incurred in the ordinary course of business and
consistent with past practice and except for any payment, discharge or

    Section 4.02.  NO SOLICITATION.  (a) The Company shall not, directly or

the Company or any of its subsidiaries, solicit or encourage the initiation of
(including by way of furnishing information) any inquiries or proposals
regarding any merger, sale of assets, sale of shares of capital stock
(including, without limitation, by way of a tender offer) or similar
transactions involving the Company or any subsidiaries of the Company that if
consummated would constitute an Alternative Transaction (as defined in Section
7.01) (any of the foregoing inquiries or proposals being referred to herein as
an "ACQUISITION PROPOSAL"). Nothing contained in this Agreement shall prevent
the Board of Directors of the Company from (i) furnishing information to a third
party which has made a BONA FIDE Acquisition Proposal that is a Superior
Proposal (as defined below) not solicited in violation of this Agreement,
PROVIDED that such third party has executed an agreement with confidentiality
provisions substantially similar to those then

                                      A-34
<PAGE>
in effect between the Company and Parent, or (ii) subject to compliance with the
other terms of this Section 4.02, including Section 4.02(c), considering and
negotiating a bona fide Acquisition Proposal that is a Superior Proposal not
solicited in violation of this Agreement; PROVIDED, HOWEVER, that, as to each of
clauses (i) and (ii), (x) such actions occur at a time prior to approval of the
Merger and this Agreement at the Company Stockholders Meeting and (y) the Board
of Directors of the Company reasonably determines in good faith (after due
consultation with independent counsel, which may be Shearman & Sterling) that it
is or is reasonably likely to be required to do so in order to discharge
properly its fiduciary duties. For purposes of this Agreement, a "SUPERIOR
PROPOSAL" means any proposal made by a third party to acquire, directly or
indirectly, for consideration consisting of cash and/or securities, all of the
equity securities of the Company entitled to vote generally in the election of
directors or all or substantially all the assets of the Company, on terms which
the Board of Directors of the Company reasonably believes (i) (after
consultation with a financial advisor of nationally recognized reputation) to be
more favorable from a financial point of view to its stockholders than the
Merger and the transactions contemplated by this Agreement taking into account
at the time of determination any changes to the financial terms of this
Agreement proposed by Parent and (ii) to be more favorable to the Company than
the Merger and the transactions contemplated by this Agreement after taking into
account all pertinent factors deemed relevant by the Board of Directors of the
Company under the laws of the State of Delaware; PROVIDED, HOWEVER, that a
Superior Proposal may be subject to a due diligence review of confidential
information and to other customary conditions.

    (b) The Company shall immediately notify Parent and Merger Sub after receipt
of any Acquisition Proposal, or any modification of or amendment to any
Acquisition Proposal, or any request for nonpublic information relating to the
Company or any of its subsidiaries in connection with an Acquisition Proposal or
for access to the properties, books or records of the Company or any subsidiary
by any person or entity that informs the Board of Directors of the Company or
such subsidiary that it is considering making, or has made, an Acquisition
Proposal. Such notice shall be made orally and in writing, and shall indicate
the identity of the person making the Acquisition Proposal or intending to make
an Acquisition Proposal or requesting non-public information or access to the
books and records of the Company, the terms of any such Acquisition Proposal or
modification or amendment to an Acquisition Proposal, and whether the Company is
providing or intends to provide the person making the Acquisition Proposal with
access to information concerning the Company as provided in Section 4.02(a). The
Company shall also immediately notify Parent and Merger Sub, orally and in
writing, if it enters into negotiations concerning any Acquisition Proposal.

    (c) Except to the extent the Board of Directors of the Company reasonably
determines in good faith (after due consultation with independent counsel, which
may be Shearman & Sterling) that it is or is reasonably likely to be required to
act to the contrary in order to discharge properly its fiduciary duties (and,
with respect to the approval, recommendation or entering into any, Acquisition
Proposal, it may take such contrary action only after the second business day
following Parent's and Merger Sub's receipt of written notice of the Board of
Directors' intention to do so), neither the Company nor the Board of Directors
of the Company shall withdraw or modify, or propose to withdraw or modify, in a
manner adverse to Parent or Merger Sub, the approval by such Board of Directors
of this Agreement or the Merger; PROVIDED, HOWEVER, that in all events, unless
this Agreement has been terminated in accordance with its terms, the Merger and
this Agreement shall be submitted for approval and adoption by the Company's
stockholders at the Company Stockholders Meeting and the Board of Directors
shall not recommend that stockholders vote against approval of the Merger and
adoption of this Agreement.

    (d) Nothing contained in this Section 4.02 shall prohibit the Company from
taking and disclosing to its stockholders a position required by Rule 14d-9 or
14e-2(a) promulgated under the Exchange Act or from making any disclosure to its
stockholders required by applicable law, rule or regulation.

    (e) The Company shall immediately cease and cause to be terminated any
existing discussions or negotiations with any persons (other than Parent and
Merger Sub) conducted heretofore with respect to any of the foregoing. The
Company agrees not to release any third party from the confidentiality and
standstill provisions of any agreement to which the Company is a party. Unless
this Agreement has been terminated in accordance with its terms, the Company
shall not redeem the Rights or waive or amend any provision of the Rights
Agreement to permit or facilitate the consummation of any Acquisition Proposal
or Alternative Transaction.

    (f) The Company shall ensure that the officers and directors of the Company
and the Company Significant Subsidiaries and any investment banker or other
advisor or representative retained by the Company are aware of the restrictions
described in this Section 4.02.

    Section 4.03.  CONDUCT OF BUSINESS BY PARENT PENDING THE MERGER.  Parent
covenants and agrees that during the period from the date of this Agreement and
continuing until the earlier of the termination of this Agreement or the
Effective Time, except as set forth in Section 4.03 of the Parent Disclosure
Schedule or unless the Company shall otherwise agree in writing, (i) Parent
shall conduct its business, and cause the businesses of its subsidiaries to be
conducted, in the ordinary course of business and consistent with past practice,
including actions taken by Parent or its subsidiaries in contemplation of the
Merger, and (ii) Parent shall not directly or indirectly do, or propose to do,
any of the following without the prior written consent of the Company:

    (a) amend or otherwise change Parent's Charter Documents;

    (b) acquire or agree to acquire, by merging or consolidating with, by
purchasing an equity interest in or a portion of the assets of, or by any other
manner, any business or any corporation, partnership, association or other
business organization or division thereof, or otherwise acquire or agree to
acquire any assets of any other person, or dispose of any assets, which, in any
such case, would materially delay or prevent the consummation of the Merger and
the other transactions contemplated by this Agreement;

    (c) declare, set aside, make or pay any dividend or other distribution
(whether in cash, stock or property or any combination thereof) in respect of
any of its capital stock, except that a wholly owned subsidiary of Parent may
declare and pay a dividend to its parent, and except that Parent may declare and
pay quarterly cash dividends on the Parent Common Shares of $0.025 per share
consistent with past practice;

    (d) take any action to change its accounting policies or procedures
(including, without limitation, procedures with respect to revenue recognition,
payments of accounts payable and collection of accounts receivable), except as
required by a change in GAAP occurring after the date hereof; or

    (e) take or agree in writing or otherwise to take any action that would make
any of the representations or warranties of Parent contained in this Agreement
untrue or incorrect or prevent Parent from performing or cause Parent not to
perform its covenants hereunder.

in the two preceding sentences of this Section 5.02 (but not the first sentence
of this Section 5.02) to the extent that the Board of Directors of the Company
reasonably determines (after due consultation with independent counsel, which
may be Shearman & Sterling) that it is or is reasonably likely that any such
action is inconsistent with the proper discharge of its fiduciary duties;
PROVIDED, HOWEVER, that in no event shall the Board of Directors recommend that
the Company's stockholders vote against approval of the Merger and adoption of
the Merger Agreement at the Company Stockholders Meeting.

    Section 5.03.  ACCESS TO INFORMATION; CONFIDENTIALITY.  Upon reasonable
notice and subject to restrictions contained in confidentiality agreements or

accountants, counsel and other representatives (collectively the
"REPRESENTATIVES") of the other, reasonable access, during the period after the
execution and delivery of this Agreement and prior to the Effective Time, to its
properties, books, contracts, commitments and records and (ii) during such
period, furnish promptly to the other all information concerning its business,

    Section 5.04.  CONSENTS; APPROVALS.  The Company, Parent and Merger Sub

all required filings in connection therewith.

    Section 5.05.  AGREEMENTS WITH RESPECT TO AFFILIATES.  The Company shall
deliver to Merger Sub, prior to the date the Registration Statement becomes
effective under the Securities Act, a letter (the

                                      A-37
<PAGE>
"COMPANY AFFILIATE LETTER") identifying all persons who are anticipated to be
"affiliates" of the Company at the time of the Company Stockholders Meeting for
purposes of Rule 145 under the Securities Act ("RULE 145"). The Company shall
use its reasonable best efforts to cause each person who is identified as an
"affiliate" in the Affiliate Letter to deliver to Parent, prior to the date of
the Company Stockholders Meeting, a written agreement (an "AFFILIATE AGREEMENT")
restricting the sales of securities by such affiliates in accordance with the
restrictions on affiliates under Rule 145, in a form mutually agreeable to the
Company and Parent.

    Section 5.06.  INDEMNIFICATION AND INSURANCE.  (a) The Articles of
Incorporation and By-laws of the Surviving Corporation shall contain the
provisions with respect to indemnification set forth in the Company's Charter
Documents, which provisions shall not be amended, modified or otherwise repealed
for a period of six years from the Effective Time in any manner that would
adversely affect the rights thereunder as of the Effective Time of individuals
who at the Effective Time were directors, officers, employees or agents of the
Company, unless such modification is required after the Effective Time by law
and then only to the minimum extent required by such law.

    (b) The Surviving Corporation shall, to the fullest extent permitted under
applicable law or under the Surviving Corporation's Articles of Incorporation or
By-laws, indemnify and hold harmless, each present and former director, officer
or employee of the Company or any of its subsidiaries (collectively, the
"INDEMNIFIED PARTIES") against any costs or expenses (including attorneys'
fees), judgments, fines, losses, claims, damages, liabilities and amounts paid
in settlement in connection with any claim, action, suit, proceeding or
investigation, whether civil, criminal, administrative or investigative, (x)
arising out of or pertaining to the transactions contemplated by this Agreement
or (y) otherwise with respect to any acts or omissions occurring at or prior to
the Effective Time, to the same extent as provided in the Company's Charter
Documents or any applicable contract or agreement as in effect on the date
hereof, in each case for a period of six years after the date hereof. In the
event of any such claim, action, suit, proceeding or investigation (whether
arising before or after the Effective Time) and subject to the specific terms of
any indemnification contract, (i) any counsel retained by the Indemnified
Parties for any period after the Effective Time shall be reasonably satisfactory
to the Surviving Corporation, (ii) after the Effective Time, the Surviving
Corporation shall pay the reasonable fees and expenses of such counsel, promptly
after statements therefor are received and (iii) the Surviving Corporation will
cooperate in the defense of any such matter; PROVIDED, HOWEVER, that the
Surviving Corporation shall not be liable for any settlement effected without
its written consent (which consent shall not be unreasonably withheld); and
PROVIDED, FURTHER, that, in the event that any claim or claims for
indemnification are asserted or made within such six-year period, all rights to
indemnification in respect of any such claim or claims shall continue until the
disposition of any and all such claims. The Indemnified Parties as a group may
retain only one law firm to represent them in each applicable jurisdiction with
respect to any single action unless there is, under applicable standards of
professional conduct, a conflict on any significant issue between the positions
of any two or more Indemnified Parties, in which case each Indemnified Person
with respect to whom such a conflict exists (or group of such Indemnified
Persons who among them have no such conflict) may retain one separate law firm
in each applicable jurisdiction.

    (c) The Surviving Corporation shall honor and fulfill in all respects the
obligations of the Company pursuant to indemnification agreements and employment
agreements (the employee parties under such agreements being referred to as the
"OFFICER EMPLOYEES") with the Company's directors and officers (including former
directors and officers) existing at or before the Effective Time, PROVIDED such
agreements have not been entered into or modified in violation of Section
4.01(f).

    (d) 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 existing policy or, if

                                      A-38
<PAGE>
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.

    (e) From and after the Effective Time, Parent shall unconditionally
guarantee the timely payment of all funds owing by, and the timely performance
of all other obligations of, the Surviving Corporation under this Section 5.06.

    (f) This Section shall survive the consummation of the Merger at the
Effective Time, is intended to benefit the Company, the Surviving Corporation
and the Indemnified Parties and the Officer Employees, shall be binding on all
successors and assigns of the Surviving Corporation and shall be enforceable by
the Indemnified Parties.

    Section 5.07.  NOTIFICATION OF CERTAIN MATTERS.  The Company shall give
prompt notice to Parent and Merger Sub, and Parent and Merger Sub shall give
prompt notice to the Company, of (i) the occurrence or nonoccurrence of any
event the occurrence or nonoccurrence of which would reasonably be expected to
cause any representation or warranty of the notifying party contained in this
Agreement to be materially untrue or inaccurate, or (ii) any failure of the
Company, Parent or Merger Sub, as the case may be, materially to comply with or
satisfy any covenant, condition or agreement to be complied with or satisfied by
it hereunder; PROVIDED, HOWEVER, that the delivery of any notice pursuant to
this Section shall not limit or otherwise affect the remedies available
hereunder to the party receiving such notice.

    Section 5.08.  FURTHER ACTION/TAX TREATMENT.  Upon the terms and subject to
the conditions hereof, each of the parties hereto shall use all reasonable
efforts to take, or cause to be taken, all actions and to do, or cause to be
done, all other things necessary, proper or advisable to consummate and make
effective as promptly as practicable the transactions contemplated by this
Agreement, to obtain in a timely manner all necessary waivers, consents and
approvals and to effect all necessary registrations and filings, and otherwise
to satisfy or cause to be satisfied all conditions precedent to its obligations
under this Agreement. The foregoing covenant shall not include any obligation by
Parent to agree to divest, abandon, license or take similar action with respect
to any material assets (tangible or intangible) of Parent or the Company or any
of their subsidiaries. The term "material" for purposes of the preceding
sentence means any assets to which are attributable annual sales in an amount
equal to 1% or more of the Company's annual sales for the fiscal year ended June
30, 1998. Subject to Section 6.04, each of Parent, Merger Sub and the Company
shall use its reasonable best efforts to cause the Merger to qualify, and will
not (either before or after consummation of the Merger) knowingly take any
actions, or fail to take any action, that might reasonably be expected to
prevent the Merger from qualifying as a reorganization under the provisions of
Section 368 of the Code that is not subject to Section 367(a)(1) of the Code
pursuant to Treasury Regulation Section 1.367(a)-(3)(c) (other than with respect
to Company stockholders who are or will be "5% transferee stockholders" within
the meaning of Treasury Regulation Section 1.367(a)-3(c)(5)(ii)). Subject to
Section 6.04, Parent shall, and shall use its reasonable best efforts to cause
the Surviving Corporation to, report, to the extent required by the Code, the
Merger for United States federal income tax purposes as a reorganization within
the meaning of Section 368 of the Code.

    Section 5.09.  PUBLIC ANNOUNCEMENTS.  Parent and the Company shall consult
with each other before issuing any press release or making any written public
statement with respect to the Merger or this Agreement and shall not issue any
such press release or make any such public statement without the prior consent
of the other party, which shall not be unreasonably withheld; PROVIDED, HOWEVER,
that either party may, without the prior consent of the other, issue such press
release or make such public statement as may upon the advice of counsel be
required by law or the rules and regulations of the NYSE if it has used all
reasonable efforts to consult with the other party.

delivered by Merger Sub to the holders of Company Common Stock in the Merger to
be listed, upon official notice of issuance, on the NYSE prior to the Effective
Time and the Parent Common Shares to be issued upon exercise of the Adjusted
Options to be so listed, as soon as practicable following the Effective Time.

taxes, any transfer, recording, registration and other fees, and any similar
taxes which become payable in connection with the transactions contemplated
hereby that are required or permitted to be filed on or before the Effective
Time, and the Company shall be responsible for the payment of all such taxes and
fees.

    Section 5.12.  OPTION PLANS AND BENEFITS, ETC.  (a) Prior to the Effective
Time, the parties to this Agreement shall take all such actions as shall be
necessary to effectuate the provisions of Section 1.06(c).

date of the then current offering periods under the Stock Purchase Plans to be
prior to the Effective Time and to terminate such plan as of or prior to the
Effective Time.

    (c) BENEFIT CONTINUATION. (i) From the Effective Date through June 30, 2000
(the "BENEFITS CONTINUATION PERIOD"), Parent and Merger Sub agree to provide
each person who is, as of the Effective Time, an employee of the Company or any
Company subsidiary (a "COMPANY EMPLOYEE") with employee benefits, including, but
not limited to, retirement, health and welfare benefits that are, in the
aggregate, substantially equivalent to those provided to such Company Employee
immediately prior to the Effective Time, PROVIDED that, Parent and Merger Sub
reserve the right to amend, without limitation, the retiree welfare benefit
plans with respect to the Company Employees effective as of the Effective Time.

    (ii) During the Benefit Continuation Period, Parent and Merger Sub agree to
provide each person who is, as of the Effective Time, a retired employee of the
Company or any Company subsidiary participating in any Company Benefit Plan (a
"COMPANY RETIREE") with health and welfare benefits that are, in the aggregate,
substantially equivalent to those provided to such Company Retiree immediately
prior to the Effective Time. Parent and Merger Sub reserve the right to amend
the retiree welfare benefit plans with respect to the Company Retirees effective
as of July 1, 2000.

vesting and, except as would result in duplication of benefits, calculation of
welfare benefits, under any Parent Employee Plan or subsequently established
employee benefit plan, program or arrangement maintained by Parent or any
subsidiary for which such individual is eligible, such Parent Employee Plan or
other plan, program or arrangement shall credit Company Employees who
participate therein for service on or prior to the Effective Time to the extent
such service was credited under the corresponding (if any) Company Employee Plan
with the Company or any subsidiary or any affiliate or predecessor of any of
them. In addition, Parent and Merger Sub shall (i) waive limitations on benefits
relating to any pre-existing conditions under any welfare benefit plan of Parent
or any subsidiary in which Company Employees may participate and (ii) recognize,

dental plans, deductible and out-of-pocket expenses paid by Company Employees
and their respective dependents under the Company's and any subsidiary's medical

shall assume the Company's Key Employee Retention and Severance Plan. At the
Effective Time, Parent shall assume, and through June 30, 2000, maintain, the

benefits which accrue thereunder and to maintain such plans on the same terms
and conditions MUTATIS MUTANDIS. Prior to the Effective Time, the Company shall
amend the Company's Layoff Benefits Plan to limit severance payable thereunder
to a maximum of 104 weeks of pay.

    (f) DEFERRED COMPENSATION PROGRAMS. Parent and Merger Sub agree to continue

Compensation Plan and the Company's Supplemental Executive Retirement Plan (the
"DEFERRAL PLANS"), PROVIDED that investment options with respect to deferred
monies shall be similar to those offered under the Deferral Plans as of the

each of their advisors whether to amend the Executive Deferred Compensation Plan
to eliminate the right of the participants to elect distributions upon the
occurrence of certain corporate reorganizations and to provide the administrator
of such Plan with discretionary powers consistent with those in the Company's
other Deferral Plans. The Company shall communicate, in a written document the
form and substance of which has been agreed to by the Company and Merger Sub, to
each individual who may receive a "Restricted Stock Amount" as defined in
Section 2.16 of the Company's Executive Deferred Compensation Plan, in respect
of any Restricted Share that vests on or after the Effective Date, that any such
share will not become a Restricted Stock Amount in the event that the Merger is
consummated. The Company shall communicate, in a written document the form and
substance of which has been agreed to by the Company and Merger Sub, to each
participant in the Company's Bonus Deferral Plan that stock options are no
longer available with respect to any bonus not paid before the Effective Date.
The Company shall amend the Company's Executive Deferred Compensation Plan, the
1990 Plan and the Bonus Deferral Plan, as agreed upon by the Company and Parent,
in order to effectuate the foregoing. At the Effective Time, Company Employees'
participation in the Deferral Plans shall cease with respect to future deferrals
and Company Employees shall be able to participate in the Parent Deferred
Compensation Plan on the same terms as other comparably situated employees of
Parent.

    (g) COMPANY LOAN PROGRAM. Through June 30, 2000, Parent and Merger Sub agree
to continue to maintain the Company's Loan Program (the "COMPANY LOAN PROGRAM")
and Parent and Merger Sub acknowledge that neither the consummation of the
transactions contemplated hereby nor any amendment or termination of the Company
Loan Program shall accelerate the maturity date of or otherwise affect in any
way any loans previously made to the Company's executives under the Company Loan
Program.

    (h) NO THIRD PARTY RIGHTS. It is expressly agreed that the provisions of
this Section 5.12 are not intended to be for the benefit of or otherwise be
enforceable by any third party, including, without limitation, any current or
former employee, officer, director, independent contractor or any collective
bargaining unit or employee organization.

    Section 5.13.  RIGHTS AGREEMENT.  The Board of Directors of the Company
shall take all further action (in addition to that referred to in Section 2.26),
if any, necessary in order to render the Rights (as defined in the Rights
Agreement) inapplicable to the Merger and the other transactions contemplated by
this Agreement.

    Section 5.14.  ACCOUNTANT'S LETTERS.  Upon reasonable notice from the other,
the Company shall use its best efforts to cause PricewaterhouseCoopers LLP to
deliver to Merger Sub, and Merger Sub shall use its best efforts to cause
PricewaterhouseCoopers to deliver to the Company, a letter covering such matters
as are reasonably requested by Merger Sub or the Company, as the case may be,
and as are customarily addressed in accountants' "comfort letters."

    Section 5.15.  COMPLIANCE WITH STATE PROPERTY TRANSFER LAWS.  The Company
agrees that it shall use its reasonable commercial efforts to comply promptly
with all requirements of applicable state property transfer laws as may be
required by the relevant state agency and shall take all action necessary to
cause the transactions contemplated hereby to be effected in compliance with
applicable state property transfer laws. The Company, after consultation with
Parent and Merger Sub, shall determine which actions must be taken prior to or
after the Effective Time to comply with applicable state property transfer laws.
The Company agrees to provide Parent and Merger Sub with any documents required
to be submitted to the relevant state agency prior to submission, and the
Company shall not take any action to comply with applicable state property
transfer laws without Parent's and Merger Sub's prior consent, which consent
shall not be unreasonably withheld or delayed. Parent and Merger Sub shall
provide to the Company any assistance reasonably requested by the Company with
respect to such compliance.

    Section 5.16.  CHARITIES.  After the Effective Time, Parent shall cause the
Surviving Corporation to provide charitable contributions and community support
within the communities in which the Company and each of its commercial business
units are located and do business at levels substantially comparable to the
levels of charitable contributions and community support provided by the Company
and its commercial business units within such areas for the two-year period
immediately prior to the Effective Time. Section 5.16 of the Company Disclosure
Schedule sets forth all charitable contributions and community support provided
by the Company for the two-year period immediately prior to the date hereof. It
is expressly agreed that the provisions of this Section 5.16 are not intended to
be for the benefit of or otherwise be enforceable by any third party.

MERGER.  The respective obligations of each party to effect the Merger shall be
subject to the satisfaction at or prior to the Effective Time of the following
conditions:

        (a) EFFECTIVENESS OF THE REGISTRATION STATEMENT. The Registration
    Statement shall have been declared effective by the SEC under the Securities
    Act. No stop order suspending the effectiveness of the Registration
    Statement shall have been issued by the SEC and no proceedings for that
    purpose and no similar proceeding in respect of the Proxy
    Statement/Prospectus shall have been initiated or threatened by the SEC;

        (b) STOCKHOLDER APPROVAL. This Agreement and the Merger shall have been
    approved and adopted by the requisite vote of the stockholders of the
    Company;

        (c) ANTITRUST. All waiting periods applicable to the consummation of the
    Merger under the HSR Act shall have expired or been terminated, and all
    clearances and approvals required to be obtained in respect of the Merger
    prior to the Effective Time under any Non-U.S. Monopoly Laws shall have been
    obtained, except where the failure to have obtained any such clearances or
    approvals with respect to any Non-U.S. Monopoly Laws would not reasonably be
    expected to have a Material Adverse Effect on the Company, Parent or
    Parent's electrical and electronic component business;

        (d) GOVERNMENTAL ACTIONS. There shall not have been instituted, pending
    or threatened any action or proceeding (or any investigation or other
    inquiry that is reasonably likely to result in such an action or proceeding)
    by any governmental authority or administrative agency before any
    governmental authority, administrative agency or court of competent
    jurisdiction, United States or non-United States, that is reasonably likely
    to result in an order, nor shall there be in effect any judgment, decree or
    order of any governmental authority, administrative agency or court of

                                      A-42
<PAGE>
    competent jurisdiction, or any other legal restraint (i) preventing or
    seeking to prevent consummation of the Merger, (ii) prohibiting or seeking
    to prohibit, or limiting or seeking to limit, Parent from exercising all
    material rights and privileges pertaining to its ownership of the Surviving
    Corporation or the ownership or operation by Parent or any of its
    subsidiaries of all or a material portion of the business or assets of the
    Surviving Corporation and its subsidiaries, or (iii) compelling or seeking
    to compel Parent or any of its subsidiaries to dispose of or hold separate
    all or any material portion of the business or assets of Parent or any of
    its subsidiaries (including the Surviving Corporation and its subsidiaries),
    as a result of the Merger or the transactions contemplated by this
    Agreement;

        (e) ILLEGALITY. No statute, rule, regulation or order shall be enacted,
    entered, enforced or deemed applicable to the Merger which makes the
    consummation of the Merger illegal; and

        (f) TAX OPINIONS. Subject to Section 6.04, the Company shall have
    received a written opinion of Shearman & Sterling (the "COMPANY TAX
    OPINION"), and Merger Sub shall have received a written opinion of
    PricewaterhouseCoopers LLP (the "PARENT TAX OPINION"), in form and substance
    reasonably satisfactory to each of them, to the effect that (i) the Merger
    will constitute a reorganization within the meaning of Section 368 of the
    Code and (ii) the transfer of Company Common Stock by Company stockholders
    pursuant to the Merger, other than Company stockholders who are or will be
    "5% transferee stockholders" within the meaning of Treasury Regulation
    Section 1.367(a)-3(c)(5)(ii), will qualify for an exception under Treasury
    Regulation Section 1.367(a)-3 and, accordingly, Parent will be treated as a
    corporation for United States federal income tax purposes. Each party agrees
    to make all customary and reasonable representations and covenants to such
    counsel in connection with the rendering of such opinions.

    Section 6.02.  ADDITIONAL CONDITIONS TO OBLIGATIONS OF PARENT AND MERGER

    by this Agreement, (ii) those representations and warranties which address
    matters only as of a particular date (which shall have been true and correct
    as of such date, subject to clause (iii)), or (iii) where the failure to be
    true and correct would not reasonably be expected, individually or in the
    aggregate with all other such failures, to have a Material Adverse Effect,

    to such effect signed by the Chief Executive Officer or Chief Financial
    Officer of the Company;

        (b) AGREEMENTS AND COVENANTS. The Company shall have performed or

    Officer of the Company; PROVIDED HOWEVER, that unless the Company knowingly
    breaches Section 4.01(k), the Company shall have been deemed to have
    complied with Section 4.01(k) unless the failure to comply with such section
    would also result in the failure of the condition referred to in Section
    6.02(a);

        (c) CONSENTS OBTAINED. All material consents, waivers, approvals,
    authorizations or orders required to be obtained, and all filings required

    this Agreement and the consummation by it of the transactions contemplated
    hereby shall have been obtained and made by the Company, except where the

    with all other such failures, to have a Material Adverse Effect on the
    Company or Parent; and

                                      A-43
<PAGE>
        (d) RIGHTS AGREEMENT. A Distribution Date shall not have occurred under
    the Rights Agreement.

    Section 6.03.  ADDITIONAL CONDITIONS TO OBLIGATION OF THE COMPANY.  The
obligation of the Company to effect the Merger is also subject to the following
conditions:

        (a) REPRESENTATIONS AND WARRANTIES. The representations and warranties
    of Parent and Merger Sub contained in this Agreement shall be true and
    correct in all respects on and as of the Effective Time, with the same force

    changes contemplated by this Agreement, (ii) those representations and
    warranties which address matters only as of a particular date (which shall
    have been true and correct as of such date, subject to clause (iii)), or
    (iii) where the failure to be true and correct would not reasonably be
    expected, individually or in the aggregate with all other such failures, to
    have a Material Adverse Effect, and the Company shall have received a
    certificate to such effect signed by the Chief Executive Officer or Chief
    Financial Officer of Parent;

        (b) AGREEMENTS AND COVENANTS. Parent and Merger Sub shall have performed
    or complied in all material respects with all agreements and covenants

    authorizations or orders required to be obtained, and all filings required
    to be made, by Parent or Merger Sub for the authorization, execution and
    delivery of this Agreement and the consummation by them of the transactions

    Sub, except where the failure to receive such consents, waivers, approvals,
    authorizations or orders would not reasonably be expected, individually or
    in the aggregate with all other such failures, to have a Material Adverse
    Effect on the Company or Parent;

        (d) LISTING. The Parent Common Shares issuable in connection with the
    Merger and upon exercise of the Adjusted Options shall have been authorized
    for listing on the NYSE upon official notice of issuance; and

        (e) SHAREHOLDER RIGHTS PLAN. A Distribution Date shall not have occurred
    under Parent's Shareholder Rights Plan dated November 6, 1996, as amended.

    Section 6.04.  FAILURE TO DELIVER TAX OPINIONS.  In the event that or
PricewaterhouseCoopers LLP notifies Parent and Merger Sub in writing that it
cannot render the Parent Tax Opinion (as reasonably determined by
PricewaterhouseCoopers LLP and concurred in by Shearman & Sterling), or Shearman
& Sterling notifies the Company in writing that it cannot render the Company Tax
Opinion (as reasonably determined by Shearman & Sterling and concurred in by
PricewaterhouseCoopers LLP), the Company, within three business days of receipt
of such notice from Shearman & Sterling or a copy of such PricewaterhouseCoopers
LLP notice, may provide Parent and Merger Sub with written notice that it elects
to proceed to consummate this Agreement notwithstanding the failure to satisfy
the condition set forth in Section 6.01(f) (the "TAX OPINION CONDITION"). In
such event, and any other provision of this Agreement notwithstanding, the Tax
Opinion Condition shall be deemed waived by the parties to this Agreement, and
Parent, Merger Sub and the Company shall take all steps necessary to effectuate
a merger (the "NEW MERGER") of a wholly-owned direct or indirect subsidiary of
Parent ("NEW MERGER SUB") with and into the Company, with the Company being the
Surviving Corporation, in accordance with the provisions of the DGCL and any
other applicable jurisdiction. Except as may be necessary to reflect the change
in the transaction structure to the New Merger and the jurisdiction of New
Merger Sub, the terms of this Agreement, including the provisions of Section
1.06, shall govern the New Merger, and the references in this Agreement to
Merger Sub, the Surviving Corporation and the

                                      A-44
<PAGE>
Merger shall be deemed references, MUTATIS MUTANDIS, to New Merger Sub, the
Company and the New Merger, respectively. The waiver of the Tax Opinion
Condition, in accordance with and in the circumstances contemplated by this
Section, shall not constitute a waiver of any other condition to the Merger or
any other provisions of this Agreement.

                                  ARTICLE VII
                                  TERMINATION

    Section 7.01.  TERMINATION.  This Agreement may be terminated at any time
prior to the Effective Time, notwithstanding approval thereof by the
stockholders of the Company:

        (a) by mutual written consent duly authorized by the Boards of Directors
    of Parent and the Company; or

        (b) by either Parent or the Company if the Merger shall not have been
    consummated by November 30, 1999 (other than for the reasons set forth in
    clause (d) below); PROVIDED, HOWEVER, that the right to terminate this
    Agreement under this Section 7.01(b) shall not be available to any party
    whose failure to fulfill any obligation under this agreement has been the
    cause of, or resulted in, the failure of the Merger to be consummated on or
    prior to such date; or

        (c) by either Parent or the Company if a court of competent jurisdiction
    or governmental, regulatory or administrative agency or commission shall
    have issued a nonappealable final order, decree or ruling or taken any other
    nonappealable final action having the effect of permanently restraining,
    enjoining or otherwise prohibiting the Merger; or

        (d) by either Parent or the Company if the Company Stockholders Meeting
    has not been held by November 30, 1999, or if the stockholders of the
    Company shall not have approved the Merger and adopted this Agreement at the
    Company Stockholders Meeting; or

        (e) by Parent, if, whether or not permitted to do so by this Agreement,
    the Board of Directors of the Company or the Company shall (x) (i) withdraw,
    modify or change its approval or recommendation of this Agreement or the
    Merger in a manner adverse to Parent; (ii) approve or recommend to the
    stockholders of the Company an Acquisition Proposal or Alternative
    Transaction; or (iii) approve or recommend that the stockholders of the
    Company tender their shares in any tender or exchange offer that is an
    Alternative Transaction or (y) take any position or make any disclosures to
    the Company's stockholders permitted pursuant to Section 4.02(d) which has
    the effect of any of the foregoing; or

        (f) by the Company, in order to accept a Superior Proposal, provided
    that the Merger and this Agreement shall not theretofore have been approved
    at the Company Stockholders Meeting; the Board of Directors of the Company
    reasonably determines in good faith (after due consultation with independent
    counsel, which may be Shearman & Sterling), that it is or is reasonably
    likely to be required to accept such proposal in order to discharge properly
    its fiduciary duties; the Company shall in fact accept such proposal; and
    the Company shall have complied in all respects with the provisions of
    Section 4.02; or

        (g) by Parent or the Company, if any representation or warranty of the
    Company, or Parent and Merger Sub, respectively, set forth in this Agreement
    shall be untrue when made, such that the conditions set forth in Section
    6.02(a) or 6.03(a), as the case may be, would not be satisfied (in each
    case, a "TERMINATING MISREPRESENTATION"); PROVIDED that, if such Terminating
    Misrepresentation is curable prior to November 30, 1999 by the Company or
    Parent, as the case may be, through the exercise of its reasonable best
    efforts to eliminate, undo or reverse the event or circumstance giving rise
    to such Terminating Misrepresentation and for so long as the Company or
    Parent, as

                                      A-45
<PAGE>
    the case may be, continues to exercise such reasonable best efforts, neither
    Parent nor the Company, respectively, may terminate this Agreement under
    this Section 7.01(g); or

        (h) by Parent, if any representation or warranty of the Company shall
    have become untrue such that the condition set forth in Section 6.02(a)
    would not be satisfied, or by the Company, if any representation or warranty
    of Parent and Merger Sub shall have become untrue such that the condition
    set forth in Section 6.03(a) would not be satisfied (in each case, a
    "TERMINATING CHANGE"), in either case other than by reason of a Terminating
    Breach (as hereinafter defined); PROVIDED that, if any such Terminating
    Change is curable prior to November 30, 1999 by the Company or Parent, as
    the case may be, through the exercise of its reasonable best efforts, and
    for so long as the Company or Parent, as the case may be, continues to
    exercise such reasonable best efforts, neither Parent nor the Company,
    respectively, may terminate this Agreement under this Section 7.01(h); or

        (i) by Parent or the Company, upon a breach of any covenant or agreement
    on the part of the Company or Parent, respectively, set forth in this
    Agreement such that the conditions set forth in Section 6.02(b) or 6.03(b),
    as the case may be, would not be satisfied (in each case, a "TERMINATING
    BREACH"); PROVIDED that, except for any breach of the Company's obligations
    under Section 4.02, if such Terminating Breach is curable prior to November
    30, 1999 by the Company or Parent, as the case may be, through the exercise
    of its reasonable best efforts and for so long as the Company or Parent, as
    the case may be, continues to exercise such reasonable best efforts, neither
    Parent nor the Company, respectively, may terminate this Agreement under
    this Section 7.01(i).

    As used herein, "ALTERNATIVE TRANSACTION" means any of (i) a transaction
pursuant to which any person (or group of persons) other than Parent or its
affiliates (a "THIRD PARTY") acquires or would acquire more than 20% of the
outstanding shares of any class of equity securities of the Company, whether
from the Company or pursuant to a tender offer or exchange offer or otherwise,
(ii) a merger or other business combination involving the Company pursuant to
which any Third Party acquires more than 20% of the outstanding equity
securities of the Company or the entity surviving such merger or business
combination, (iii) any transaction pursuant to which any Third Party acquires or
would acquire control of assets (including for this purpose the outstanding
equity securities of subsidiaries of the Company and securities of the entity
surviving any merger or business combination including any of the Company's
subsidiaries) of the Company, or any of its subsidiaries, having a fair market
value (as determined by the Board of Directors of the Company in good faith)
equal to more than 20% of the fair market value of all the assets of the Company
and its subsidiaries, taken as a whole, immediately prior to such transaction,
or (iv) any other consolidation, business combination or similar transaction
involving the Company or any of the Company Significant Subsidiaries, other than
the transactions contemplated by this Agreement; PROVIDED, HOWEVER, that the
term Alternative Transaction shall not include any acquisition of securities by
a broker dealer in connection with a bona fide public offering of such
securities.

    Section 7.02.  EFFECT OF TERMINATION.  In the event of the termination of
this Agreement pursuant to Section 7.01, this Agreement shall forthwith become
void and there shall be no liability on the part of any party hereto or any of
its affiliates, directors, officers or shareholders except that (i) the Company
or Parent or Merger Sub may have liability as set forth in Section 7.03 and
Section 8.01 hereof, and (ii) nothing herein shall relieve the Company, Parent
or Merger Sub from liability for any willful material breach hereof (it being
understood that the mere existence of a Material Adverse Effect, by itself,
shall not constitute such a willful material breach).

    Section 7.03.  FEES AND EXPENSES.  (a) Except as set forth in this Section
7.03, all fees and expenses incurred in connection with this Agreement and the
transactions contemplated hereby shall be paid by the party incurring such
expenses, whether or not the Merger is consummated; PROVIDED, HOWEVER, that
Parent and the Company shall share equally (i) all SEC filing fees and printing
expenses

                                      A-46
<PAGE>
incurred in connection with the printing and filing of the Proxy
Statement/Prospectus (including any preliminary materials related thereto) and
the Registration Statement (including financial statements and exhibits) and any
amendments or supplements thereto and (ii) all conveyance and similar taxes
required to be paid prior to the Effective Time under Section 5.11.

    (b) The Company shall pay Parent a fee of $100 million (the "FEE"), and
shall pay Parent's respective actual, documented and reasonable out-of-pocket
expenses, relating to the transactions contemplated by this Agreement
(including, but not limited to, fees and expenses of counsel and accountants and
out-of-pocket expenses (but not fees) of financial advisors) ("EXPENSES," as
applicable to either Parent or the Company), such payment of Expenses not to
exceed $7.5 million, upon the first to occur of any of the following events:

        (i) the termination of this Agreement by Parent or the Company pursuant
    to Section 7.01(d), PROVIDED that, if this Agreement is terminated because
    the stockholders have not approved and adopted the Merger and this Agreement
    at the Company's Stockholders Meeting, the Fee and Expenses shall only be
    payable under this clause (i) if there shall occur a Payment Trigger; or

        (ii) the termination of this Agreement by Parent pursuant to clause
    (x)(ii) or (x)(iii) of Section 7.01(e) or the corresponding application of
    clause (y) thereof to clause (x)(ii) or (x)(iii); or

        (iii) the termination of this Agreement by the Company pursuant to
    Section 7.01(f); or

        (iv) the termination of this Agreement by Parent pursuant to Section
    7.01(i) as a result of a willful breach by the Company; PROVIDED that the
    Fee and Expenses shall only be payable under this clause (iv) if there shall
    occur a Payment Trigger.

    The term "PAYMENT TRIGGER" means either (A) at the time of the Company
Stockholders Meeting, in the case of clause (i) above, or at the time of the
Terminating Breach, in the case of clause (iv) above, there shall be outstanding
a bona fide Acquisition Proposal which has been made directly to the
stockholders of the Company or has otherwise become publicly known or there
shall be outstanding an announcement by any credible third party of a bona fide
intention to make an Acquisition Proposal (in each case whether or not
conditional and whether or not such proposal shall have been rejected by the
Board of Directors of the Company) or (B) an Alternative Transaction shall be
publicly announced by the Company or any third party within 12 months following
the date of termination of this Agreement and such transaction shall at any time
thereafter be consummated on substantially the terms theretofore announced.

    (c) Upon a termination of this Agreement by Parent pursuant to Section
7.01(g), the Company shall pay to Parent and Merger Sub their respective
Expenses relating to the transactions contemplated by this Agreement, but in no
event more than $7.5 million. Upon termination of this Agreement by the Company
pursuant to Section 7.01(g), Merger Sub shall pay to the Company the Expenses of
the Company relating to the transactions contemplated by this Agreement, but in
no event more than $7.5 million.

    (d) The Fee and/or Expenses payable pursuant to Section 7.03(b) or Section
7.03(c) shall be paid within one business day after a demand for payment
following the first to occur of any of the events described in Section 7.03(b)
or Section 7.03(c); PROVIDED that in no event shall the Company or Parent, as
the case may be, be required to pay such Fee and/or Expenses to the entities
entitled thereto, if, immediately prior to the termination of this Agreement,
the other entity was entitled to terminate this Agreement pursuant to Section
7.01(g), Section 7.01(h) or Section 7.01(i).

    (e) Each of the Company and Parent agrees that the payments provided for in
Section 7.03(b) or (c), as the case may be, shall be the sole and exclusive
remedies of Parent upon a termination of this Agreement pursuant to Sections
7.01(d), (e) and (f) or a termination pursuant to Section 7.01(g) (but only if
the Terminating Misrepresentation is not intentional), as the case may be, and
such remedies shall be limited to the sums stipulated in Section 7.03(b) or (c),
as the case may be, regardless of the circumstances giving rise to such
termination.

    Section 8.04.  AMENDMENT.  This Agreement may be amended by the parties
hereto by action taken by or on behalf of their respective Boards of Directors

stockholders without such further approval. This Agreement may not be amended
except by an instrument in writing signed by the parties hereto.

    Section 8.11.  FAILURE OR INDULGENCE NOT WAIVER; REMEDIES CUMULATIVE.  No
failure or delay on the part of any party hereto in the exercise of any right
hereunder shall impair such right or be construed to be a waiver of, or

nor shall any single or partial exercise of any such right preclude any other or
further exercise thereof or of any other right. All rights and remedies existing
under this Agreement are cumulative to, and not exclusive of, any rights or

Board of Directors
Raychem Corporation
300 Constitution Drive
Menlo Park, California 94025

Members of the Board of Directors:

    We understand that Raychem Corporation ("Raychem" or the "Company"), Tyco
International Ltd. ("Tyco") and Tyco International (PA) Inc., a wholly owned
subsidiary of Tyco ("Tyco (PA)"), propose to enter into an Agreement and Plan of
Merger and Reorganization, substantially in the form of the draft dated May 18,
1999 (the "Merger Agreement"), which provides, among other things, for the
merger (the "Merger") of Raychem with and into Tyco (PA). Pursuant to the
Merger, each outstanding share of common stock, par value $1.00 per share (the
"Raychem Common Stock"), of Raychem, other than shares held in treasury or held
by Tyco, Tyco (PA) or any affiliate of Tyco or as to which dissenters' rights
have been perfected, will be converted into the right to elect to receive a
certain number of shares of common stock, par value $0.20 per share (the "Tyco
Common Stock"), of Tyco or a certain amount of cash or a combination of Tyco
Common Stock and cash, subject to proration if too many elections with respect
to cash or Tyco Common Stock, as the case may be, are received. The total amount
of cash in aggregate to be received by the holders of shares of Raychem Common
Stock is $18.50 multiplied by the number of shares of Raychem Common Stock
outstanding as of the consummation of the Merger, excluding any shares to which
dissenters' rights have been perfected. The total number of shares of Tyco
Common Stock in aggregate to be received by the holders of shares of Raychem
Common Stock is 0.2070 multiplied by the number of shares of Raychem Common
Stock outstanding as of the consummation of the Merger. The terms and conditions
of the Merger are more fully set forth in the Merger Agreement.

    You have asked for our opinion as to whether the consideration to be
received by the holders of shares of Raychem Common Stock pursuant to the Merger
Agreement is fair from a financial point of view to such holders.

    For purposes of the opinion set forth herein, we have:

    (i) reviewed certain publicly available financial statements and other
        information of the Company and Tyco;

    (ii) reviewed certain internal financial statements and other financial and
         operating data concerning the Company prepared by the management of the
         Company;

   (iii) reviewed certain internal financial statements and other financial and
         operating data concerning Tyco prepared by the management of Tyco;

    (iv) analyzed certain financial projections prepared by the management of
         the Company;

    (v) analyzed certain financial projections prepared by the management of
        Tyco;

    (vi) discussed the past and current operations and financial condition and
         the prospects of the Company, including information relating to certain
         strategic, financial and operational benefits anticipated from the
         Merger, with senior executives of the Company;

   (vii) discussed the past and current operations and financial condition and
         the prospects of Tyco, including information relating to certain
         strategic, financial and operational benefits anticipated from the
         Merger, with senior executives of Tyco;

  (viii) reviewed the reported prices and trading activity for the Raychem
         Common Stock and the Tyco Common Stock;

    (ix) compared the financial performance of the Company and Tyco and the
         prices and trading activity of the Raychem Common Stock and the Tyco
         Common Stock with that of certain other comparable publicly-traded
         companies and their securities;

    (x) reviewed the financial terms, to the extent publicly available, of
        certain acquisition transactions we deem comparable;

    (xi) analyzed the pro forma impact of the Merger on Tyco's earnings per
         share;

   (xii) reviewed the draft Merger Agreement and certain related documents; and

  (xiii) performed such other analyses and considered such other factors as we
         have deemed appropriate.

    We have assumed and relied upon without independent verification the
accuracy and completeness of the information reviewed by us for the purposes of
this opinion. With respect to the financial projections, including information
relating to certain strategic, financial and operational benefits anticipated
from the Merger, we have assumed that they have been reasonably prepared on
bases reflecting the best currently available estimates and judgments of the
future financial performance of the Company. We have also relied upon the
assessment by the management of the Company of the cost savings and benefits
expected to result from the Merger. In addition, we have assumed that the Merger
will be consummated in accordance with the terms set forth in the Merger
Agreement, including, among other things, that the Merger will be treated with
respect to the stock consideration as tax-free pursuant to the Internal Revenue
Code of 1986, as amended. We have not made any independent valuation or
appraisal of the assets or liabilities of the Company, nor have we been
furnished with any such appraisals. Our opinion is necessarily based on
financial, economic, market and other conditions as in effect on, and the
information made available to us as of, the date hereof.

    In arriving at our opinion, we were not authorized to solicit, and did not
solicit, interest from any party with respect to the acquisition, business
combination or other extraordinary transaction involving the Company or any of
its assets.

    We have acted as financial advisor to the Board of Directors of the Company
in connection with this transaction and will receive a fee for our services. In
the past, Morgan Stanley & Co. Incorporated and its affiliates have provided
financial advisory and financing services for the Company and Tyco and have
received fees for the rendering of these services.

    It is understood that this letter is for the information of the Board of
Directors of the Company and may not be used for any other purpose without our
prior written consent, except that this opinion may be included in its entirety
in any filing made by the Company in respect of the transaction with the
Securities and Exchange Commission.

    In addition, this opinion does not in any manner address the prices at which
Tyco Common Stock will trade following consummation of the Merger, and Morgan
Stanley expresses no opinion or recommendation as to how stockholders of the
Company should vote at the stockholders' meeting held in connection with the
Merger.

    Based and subject to the foregoing, we are of the opinion on the date hereof
that the consideration to be received by the holders of shares of Raychem Common
Stock pursuant to the Merger Agreement is fair from a financial point of view to
such holders.

                                        Very truly yours,

                        DELAWARE GENERAL CORPORATION LAW

Section 262. Appraisal rights.

(a)  Any stockholder of a corporation of this State who holds shares of stock on
the date of the making of a demand pursuant to subsection (d) of this section
with respect to such shares, who continuously holds such shares through the
effective date of the merger or consolidation, who has otherwise complied with
subsection (d) of this section and who has neither voted in favor of the merger
or consolidation nor consented thereto in writing pursuant to Section 228 of
this title shall be entitled to an appraisal by the Court of Chancery of the
fair value of the stockholder's shares of stock under the circumstances
described in subsections (b) and (c) of this section. As used in this section,
the word "stockholder" means a holder of record of stock in a stock corporation
and also a member of record of a nonstock corporation; the words "stock" and
"share" mean and include what is ordinarily meant by those words and also
membership or membership interest of a member of a nonstock corporation; and the
words "depository receipt" mean a receipt or other instrument issued by a
depository representing an interest in one or more shares, or fractions thereof,
solely of stock of a corporation, which stock is deposited with the depository.

(b)  Appraisal rights shall be available for the shares of any class or series
of stock of a constituent corporation in a merger or consolidation to be
effected pursuant to Section 251 (other than a merger effected pursuant to
Section 251(g) of this title), Section 252, Section 254, Section 257, Section
258, Section 263 or Section 264 of this title:

    (1)  Provided, however, that no appraisal rights under this section shall be
    available for the shares of any class or series of stock, which stock, or
    depository receipts in respect thereof, at the record date fixed to
    determine the stockholders entitled to receive notice of and to vote at the
    meeting of stockholders to act upon the agreement of merger or
    consolidation, were either (i) listed on a national securities exchange or
    designated as a national market system security on an interdealer quotation
    system by the National Association of Securities Dealers, Inc. or (ii) held
    of record by more than 2,000 holders; and further provided that no appraisal
    rights shall be available for any shares of stock of the constituent
    corporation surviving a merger if the merger did not require for its
    approval the vote of the stockholders of the surviving corporation as
    provided in subsection (f) of Section 251 of this title.

    (2)  Notwithstanding paragraph (1) of this subsection, appraisal rights
    under this section shall be available for the shares of any class or series
    of stock of a constituent corporation if the holders thereof are required by
    the terms of an agreement of merger or consolidation pursuant to
    SectionSection251, 252, 254, 257, 258, 263 and 264 of this title to accept
    for such stock anything except:

       a.  Shares of stock of the corporation surviving or resulting from such
       merger or consolidation, or depository receipts in respect thereof;

       b.  Shares of stock of any other corporation, or depository receipts in
       respect thereof, which shares of stock (or depository receipts in respect
       thereof) or depository receipts at the effective date of the merger or
       consolidation will be either listed on a national securities exchange or
       designated as a national market system security on an interdealer
       quotation system by the National Association of Securities Dealers, Inc.
       or held of record by more than 2,000 holders;

       c.  Cash in lieu of fractional shares or fractional depository receipts
       described in the foregoing subparagraphs a. and b. of this paragraph; or

                                      C-1
<PAGE>
       d.  Any combination of the shares of stock, depository receipts and cash
       in lieu of fractional shares or fractional depository receipts described
       in the foregoing subparagraphs a., b. and c. of this paragraph.

    (3)  In the event all of the stock of a subsidiary Delaware corporation
    party to a merger effected under Section 253 of this title is not owned by
    the parent corporation immediately prior to the merger, appraisal rights
    shall be available for the shares of the subsidiary Delaware corporation.

(c)  Any corporation may provide in its certificate of incorporation that
appraisal rights under this section shall be available for the shares of any
class or series of its stock as a result of an amendment to its certificate of
incorporation, any merger or consolidation in which the corporation is a
constituent corporation or the sale of all or substantially all of the assets of
the corporation. If the certificate of incorporation contains such a provision,
the procedures of this section, including those set forth in subsections (d) and
(e) of this section, shall apply as nearly as is practicable.

(d)  Appraisal rights shall be perfected as follows:

    (1)  If a proposed merger or consolidation for which appraisal rights are
    provided under this section is to be submitted for approval at a meeting of
    stockholders, the corporation, not less than 20 days prior to the meeting,
    shall notify each of its stockholders who was such on the record date for
    such meeting with respect to shares for which appraisal rights are available
    pursuant to subsection (b) or (c) hereof that appraisal rights are available
    for any or all of the shares of the constituent corporations, and shall
    include in such notice a copy of this section. Each stockholder electing to
    demand the appraisal of his shares shall deliver to the corporation, before
    the taking of the vote on the merger or consolidation, a written demand for
    appraisal of his shares. Such demand will be sufficient if it reasonably
    informs the corporation of the identity of the stockholder and that the
    stockholder intends thereby to demand the appraisal of his shares. A proxy
    or vote against the merger or consolidation shall not constitute such a
    demand. A stockholder electing to take such action must do so by a separate
    written demand as herein provided. Within 10 days after the effective date
    of such merger or consolidation, the surviving or resulting corporation
    shall notify each stockholder of each constituent corporation who has
    complied with this subsection and has not voted in favor of or consented to
    the merger or consolidation of the date that the merger or consolidation has
    become effective; or

    (2)  If the merger or consolidation was approved pursuant to Section 228 or
    Section 253 of this title, each consitutent corporation, either before the
    effective date of the merger or consolidation or within ten days thereafter,
    shall notify each of the holders of any class or series of stock of such
    constitutent corporation who are entitled to appraisal rights of the
    approval of the merger or consolidation and that appraisal rights are
    available for any or all shares of such class or series of stock of such
    constituent corporation, and shall include in such notice a copy of this
    section; provided that, if the notice is given on or after the effective
    date of the merger or consolidation, such notice shall be given by the
    surviving or resulting corporation to all such holders of any class or
    series of stock of a constituent corporation that are entitled to appraisal
    rights. Such notice may, and, if given on or after the effective date of the
    merger or consolidation, shall, also notify such stockholders of the
    effective date of the merger or consolidation. Any stockholder entitled to
    appraisal rights may, within 20 days after the date of mailing of such
    notice, demand in writing from the surviving or resulting corporation the
    appraisal of such holder's shares. Such demand will be sufficient if it
    reasonably informs the corporation of the identity of the stockholder and
    that the stockholder intends thereby to demand the appraisal of such
    holder's shares. If such notice did not notify stockholders of the effective
    date of the merger or consolidation, either (i) each such constitutent
    corporation shall send a second notice before the effective date of the
    merger or consolidation notifying each of the holders of any class or series
    of stock of such constitutent corporation that are entitled to appraisal
    rights of the effective date of the merger or consolidation

                                      C-2
<PAGE>
    or (ii) the surviving or resulting corporation shall send such a second
    notice to all such holders on or within 10 days after such effective date;
    provided, however, that if such second notice is sent more than 20 days
    following the sending of the first notice, such second notice need only be
    sent to each stockholder who is entitled to appraisal rights and who has
    demanded appraisal of such holder's shares in accordance with this
    subsection. An affidavit of the secretary or assistant secretary or of the
    transfer agent of the corporation that is required to give either notice
    that such notice has been given shall, in the absence of fraud, be prima
    facie evidence of the facts stated therein. For purposes of determining the
    stockholders entitled to receive either notice, each constitutent
    corporation may fix, in advance, a record date that shall be not more than
    10 days prior to the date the notice is given, provided, that if the notice
    is given on or after the effective date of the merger or consolidation, the
    record date shall be such effective date. If no record date is fixed and the
    notice is given prior to the effective date, the record date shall be the
    close of business on the day next preceding the day on which the notice is
    given.

(e)  Within 120 days after the effective date of the merger or consolidation,
the surviving or resulting corporation or any stockholder who has complied with
subsections (a) and (d) hereof and who is otherwise entitled to appraisal
rights, may file a petition in the Court of Chancery demanding a determination
of the value of the stock of all such stockholders. Notwithstanding the
foregoing, at any time within 60 days after the effective date of the merger or
consolidation, any stockholder shall have the right to withdraw his demand for
appraisal and to accept the terms offered upon the merger or consolidation.
Within 120 days after the effective date of the merger or consolidation, any
stockholder who has complied with the requirements of subsections (a) and (d)
hereof, upon written request, shall be entitled to receive from the corporation
surviving the merger or resulting from the consolidation a statement setting
forth the aggregate number of shares not voted in favor of the merger or
consolidation and with respect to which demands for appraisal have been received
and the aggregate number of holders of such shares. Such written statement shall
be mailed to the stockholder within 10 days after his written request for such a
statement is received by the surviving or resulting corporation or within 10
days after expiration of the period for delivery of demands for appraisal under
subsection (d) hereof, whichever is later.

(f)  Upon the filing of any such petition by a stockholder, service of a copy
thereof shall be made upon the surviving or resulting corporation, which shall
within 20 days after such service file in the office of the Register in Chancery
in which the petition was filed a duly verified list containing the names and
addresses of all stockholders who have demanded payment for their shares and
with whom agreements as to the value of their shares have not been reached by
the surviving or resulting corporation. If the petition shall be filed by the
surviving or resulting corporation, the petition shall be accompanied by such a
duly verified list. The Register in Chancery, if so ordered by the Court, shall
give notice of the time and place fixed for the hearing of such petition by
registered or certified mail to the surviving or resulting corporation and to
the stockholders shown on the list at the addresses therein stated. Such notice
shall also be given by 1 or more publications at least 1 week before the day of
the hearing, in a newspaper of general circulation published in the City of
Wilmington, Delaware or such publication as the Court deems advisable. The forms
of the notices by mail and by publication shall be approved by the Court, and
the costs thereof shall be borne by the surviving or resulting corporation.

(g)  At the hearing on such petition, the Court shall determine the stockholders
who have complied with this section and who have become entitled to appraisal
rights. The Court may require the stockholders who have demanded an appraisal
for their shares and who hold stock represented by certificates to submit their
certificates of stock to the Register in Chancery for notation thereon of the
pendency of the appraisal proceedings; and if any stockholder fails to comply
with such direction, the Court may dismiss the proceedings as to such
stockholder.

(h)  After determining the stockholders entitled to an appraisal, the Court
shall appraise the shares, determining their fair value exclusive of any element
of value arising from the accomplishment or

                                      C-3
<PAGE>
expectation of the merger or consolidation, together with a fair rate of
interest, if any, to be paid upon the amount determined to be the fair value. In
determining such fair value, the Court shall take into account all relevant
factors. In determining the fair rate of interest, the Court may consider all
relevant factors, including the rate of interest which the surviving or
resulting corporation would have had to pay to borrow money during the pendency
of the proceeding. Upon application by the surviving or resulting corporation or
by any stockholder entitled to participate in the appraisal proceeding, the
Court may, in its discretion, permit discovery or other pretrial proceedings and
may proceed to trial upon the appraisal prior to the final determination of the
stockholder entitled to an appraisal. Any stockholder whose name appears on the
list filed by the surviving or resulting corporation pursuant to subsection (f)
of this section and who has submitted his certificates of stock to the Register
in Chancery, if such is required, may participate fully in all proceedings until
it is finally determined that he is not entitled to appraisal rights under this
section.

(i)  The Court shall direct the payment of the fair value of the shares,
together with interest, if any, by the surviving or resulting corporation to the
stockholders entitled thereto. Interest may be simple or compound, as the Court
may direct. Payment shall be so made to each such stockholder, in the case of
holders of uncertificated stock forthwith, and the case of holders of shares
represented by certificates upon the surrender to the corporation of the
certificates representing such stock. The Court's decree may be enforced as
other decrees in the Court of Chancery may be enforced, whether such surviving
or resulting corporation be a corporation of this State or of any state.

(j)  The costs of the proceeding may be determined by the Court and taxed upon
the parties as the Court deems equitable in the circumstances. Upon application
of a stockholder, the Court may order all or a portion of the expenses incurred
by any stockholder in connection with the appraisal proceeding, including,
without limitation, reasonable attorney's fees and the fees and expenses of
experts, to be charged pro rata against the value of all the shares entitled to
an appraisal.

(k)  From and after the effective date of the merger or consolidation, no
stockholder who has demanded his appraisal rights as provided in subsection (d)
of this section shall be entitled to vote such stock for any purpose or to
receive payment of dividends or other distributions on the stock (except
dividends or other distributions payable to stockholders of record at a date
which is prior to the effective date of the merger or consolidation); provided,
however, that if no petition for an appraisal shall be filed within the time
provided in subsection (e) of this section, or if such stockholder shall deliver
to the surviving or resulting corporation a written withdrawal of his demand for
an appraisal and an acceptance of the merger or consolidation, either within 60
days after the effective date of the merger or consolidation as provided in
subsection (e) of this section or thereafter with the written approval of the
corporation, then the right of such stockholder to an appraisal shall cease.
Notwithstanding the foregoing, no appraisal proceeding in the Court of Chancery
shall be dismissed as to any stockholder without the approval of the Court, and
such approval may be conditioned upon such terms as the Court deems just.

(l)  The shares of the surviving or resulting corporation to which the shares of
such objecting stockholders would have been converted had they assented to the
merger or consolidation shall have the status of authorized and unissued shares
of the surviving or resulting corporation.

ANTICIPATE THAT SUCH DATE WILL BE ON OR ABOUT AUGUST 12, 1999, THE DATE OF THE
SPECIAL MEETING OF RAYCHEM'S STOCKHOLDERS TO VOTE ON THE MERGER. AS A RESULT, WE
RECOMMEND THAT YOU SUBMIT THIS DOCUMENT, TOGETHER WITH YOUR RAYCHEM STOCK

DOCUMENTATION, NO LATER THAN 5:00 P.M. EASTERN TIME ON AUGUST 11, 1999.

Ladies and Gentlemen:

    Pursuant to the merger agreement, and subject to the proration rules
included in the merger agreement and described in the proxy
statement/prospectus, I hereby surrender to ChaseMellon Shareholder Services,
LLC, as exchange agent, certificate(s) representing all of my shares of Raychem
common stock listed above. I elect to have each of such shares of Raychem common
stock represented by such certificates converted according to the following
three election options, in the manner indicated in Box A below:

        (A) CASH ELECTION: The right to receive cash equal to the "per share
    amount of the merger consideration;"

        (B) STOCK ELECTION: The right to receive Tyco shares having a value
    equal to the "per share amount of the merger consideration;" or

        (C) NO ELECTION: The right to receive cash and/or shares having a value
    equal to the "per share value of the merger consideration," as provided in
    the merger agreement, for shares of Raychem common stock as to which no
    election is made.

The "per share amount of the merger consideration" is $18.50 plus the value of
0.2070 of a Tyco common share. The value of a Tyco common share for these
purposes is the average of the volume weighted average sale prices per Tyco
common share on the New York Stock Exchange for the three consecutive trading
days beginning on the date the merger becomes effective. The exchange agent will
pay cash in lieu of any fractional Tyco shares otherwise issuable in connection
with the merger.

    I understand that each election is subject to certain terms, conditions and
limitations set forth in the merger agreement, including that the aggregate
amount of cash and the aggregate number of Tyco shares to be paid or delivered
in the merger is fixed.

    - The aggregate amount of cash that is payable in the merger is equal to
      $18.50 multiplied by the number of shares of Raychem common stock
      outstanding on the date the merger becomes effective. If there are
      dissenting shares, the aggregate amount of cash will be reduced by the
      number of dissenting shares multiplied by the per share value of the
      merger consideration.

    - The aggregate number of Tyco common shares that are deliverable in the
      merger is equal to 0.2070 multiplied by the number of shares of Raychem
      common stock outstanding on the date the merger becomes effective.

    I ACKNOWLEDGE THAT THE MERGER AGREEMENT PROVIDES FOR PRORATION IF, AS A
RESULT OF THE ELECTIONS MADE BY RAYCHEM STOCKHOLDERS, EITHER THE FIXED AMOUNT OF
CASH OR THE FIXED NUMBER OF TYCO SHARES WOULD OTHERWISE BE EXCEEDED. IN SUCH A
CASE, I UNDERSTAND THAT I MAY RECEIVE A COMBINATION OF CASH AND TYCO SHARES THAT
DIFFERS FROM MY ELECTION(S) MADE IN BOX A.

    If I am acting in a representative or fiduciary capacity for a particular
beneficial owner, I hereby certify that this document covers all of the shares
of Raychem common stock that I own in a representative or fiduciary capacity for
such particular beneficial owner.

    I hereby represent and warrant that I am, as of the date hereof, and will
be, as of the date the merger becomes effective, the registered holder of the
shares of Raychem common stock represented by the certificate(s) surrendered
with this document, with good title to such shares and full power and authority
to:

    1.  sell, assign and transfer such shares free and clear of all liens,
       restrictions, charges and encum-brances, and not subject to any adverse
       claims, and

    2.  make the election(s) indicated in Box A.

                                       3
<PAGE>
    I will, upon request, execute any additional documents necessary or
desirable to complete the surrender and exchange of my shares of Raychem common
stock. I hereby irrevocably appoint the exchange agent, as my agent, to effect
the exchange pursuant to the merger agreement and the instructions to this
document. All authority conferred by this document shall be binding upon my
successors, assigns, heirs, executors, administrators and legal representatives.
This authority shall not be affected by, and shall survive, my death or
incapacity.

                                     BOX A:
                                    ELECTION

    ALL ELECTIONS ARE SUBJECT TO THE PRORATION RULES SET FORTH IN SECTION 1.06
OF THE MERGER AGREEMENT, A COPY OF WHICH IS ATTACHED TO THE PROXY
STATEMENT/PROSPECTUS AS ANNEX A. THESE RULES ARE DESCRIBED UNDER THE CAPTION
"THE MERGER AGREEMENT--MERGER CONSIDERATION--THE PRORATION RULES" IN THE PROXY
STATEMENT/ PROSPECTUS AND IN GENERAL INSTRUCTION 3 BELOW. YOU ARE URGED TO READ
THE PROXY STATEMENT/PROSPECTUS IN ITS ENTIRETY BEFORE COMPLETING THIS DOCUMENT.

    You will be deemed not to have made an election if:

    A. No election choice is indicated in Box A;

    B.  You fail to follow the instructions in this document, including failure
       to submit your Raychem stock certificate(s) or a guarantee of their
       delivery, or otherwise fail to properly make an election;

    C.  This document, completed and accompanied by your Raychem stock
       certificate(s) or a guarantee of their delivery, is not actually received
       by the exchange agent before the election deadline; or

    D. You return this document with a guarantee of delivery of your stock
       certificates, but do not deliver the certificates within three NYSE
       trading days.

    Tyco (PA) and the exchange agent reserve the right to waive any defects in
your completion of this document, but are under no obligation to do so.

    In order for your election to be valid and to receive your merger
consideration, this document MUST be:

    - completed and signed in the space provided above and on the included
      Substitute Form W-9; and

    - received by the exchange agent, together with your Raychem stock
      certificate(s) or a guarantee of their delivery, at one of the addresses
      set forth above, prior to the election deadline.

    The allocation of the merger consideration among the Raychem stockholders
will depend upon the elections made by stockholders and the average of the
volume weighted average sale prices per Tyco common share on the NYSE for the
three consecutive trading days beginning on the date the merger becomes
effective. Raychem stockholders may submit their election until the business day
preceding the date the merger becomes effective, and it may take some time
before the exchange agent can verify the election forms and tabulate the
election results. The validity of elections submitted just prior to the election
deadline and accompanied by a guarantee of delivery will not be finally
determined until three trading days after the deadline. The three trading day
average value of Tyco common shares cannot be determined until the close of
trading on the second trading day after the date the merger becomes effective.
Because of these mechanics, there will be a period of time following
consummation of the merger before the allocation of the merger consideration can
be determined. Consequently, the payment to you of the merger consideration,
even if you made an election and delivered your Raychem stock certificates to
the exchange agent prior to the election deadline, may be delayed.

               SPECIAL ISSUANCE, PAYMENT OR DELIVERY INSTRUCTIONS

    Unless you otherwise indicate above under "Special Issuance and Payment
Instructions," the merger consideration will be delivered in your name.
Similarly, unless you otherwise indicate above under "Special Delivery
Instructions," the merger consideration will be mailed to you at the address
shown above. In the event that you complete the "Special Issuance and Payment
Instructions" box, the merger consideration will be delivered in the name of,
and will be mailed to, the indicated person or entity at the indicated address.
Before such delivery can be made, however, the exchange agent must be provided
with satisfactory evidence of the payment of, or exemption from payment of, any
applicable stock transfer taxes. In addition, you must include appropriate
signature guarantees with respect to shares of Raychem common stock for which
you give Special Issuance and Payment Instructions.

                              GENERAL INSTRUCTIONS

    You should complete and submit this document to the exchange agent prior to
the election deadline if you wish to make a cash or stock election. You can also
use this document as a letter of transmittal at any time if you wish to submit
your shares to be exchanged for the merger consideration without electing
whether to receive cash or stock. Until your Raychem stock certificates are
received and processed by the exchange agent at one of the addresses set forth
on the cover, together with such other documents as the exchange agent may
require, you will not receive your merger consideration. No interest will accrue
on any cash you are entitled to receive. If you are receiving Tyco shares, you
will be entitled to any dividends or other distributions paid on Tyco common
shares with a record date after the effective time of the merger.

    YOU MUST FILL IN THE APPROPRIATE ELECTION INFORMATION IN BOX A ABOVE TO MAKE
AN ELECTION TO RECEIVE YOUR CHOICE OF CASH AND/OR TYCO SHARES AS YOUR MERGER
CONSIDERATION.

    Your election is subject to certain terms, conditions and limitations which
are set forth in the merger agreement and described in the proxy
statement/prospectus. The merger agreement is included as Annex A to the proxy
statement/prospectus.

    1.  ELECTION DEADLINE.  The election deadline is the close of business on
the business day prior to the date the merger becomes effective. For any
election to be effective, this document, properly completed, and your related
Raychem stock certificate(s), or a guarantee of their delivery, must be received
by the exchange agent at one of the addresses shown on the cover of this
document prior to the deadline. The exchange agent will determine whether this
document or any of your Raychem stock certificates whose delivery has been
guaranteed are received on a timely basis. Any such determination will be
conclusive and binding. WE ANTICIPATE THAT THE DATE THE MERGER BECOMES EFFECTIVE
WILL BE ON OR ABOUT THE DATE OF THE SPECIAL MEETING OF RAYCHEM STOCKHOLDERS TO
VOTE ON THE MERGER, WHICH IS SCHEDULED TO BE HELD ON AUGUST 12, 1999. WE
THEREFORE RECOMMEND THAT IF YOU WISH TO MAKE AN ELECTION, YOU DELIVER THIS
DOCUMENT, TOGETHER WITH THE RELATED RAYCHEM STOCK CERTIFICATE(S) OR A GUARANTEE
OF THEIR DELIVERY, PRIOR TO 5:00 P.M. EASTERN TIME ON AUGUST 11, 1999.

    If the merger is not consummated by August 19, 1999, Tyco and Raychem will
issue a press release on the Dow Jones News Service at least five business days
before consummating the merger. The press release will inform stockholders of
the last date for submitting and/or changing their election forms.

    2.  REVOCATION OR CHANGE OF ELECTION.  An election may be:

    - revoked, if the exchange agent receives written notice prior to the
      election deadline from the record holder of the shares covered by such
      election, or

    - changed, if the exchange agent receives a completed replacement of this
      document prior to the election deadline from the record holder of the
      shares covered by such election.

If you effectively revoke an election, you may, by signed written notice to the
exchange agent, request the return of your Raychem stock certificates submitted
to the exchange agent, and they will be returned to you without charge by first
class, insured mail as promptly as practicable after receipt of such request.

    3.  ELECTION PROCEDURES/PRORATION.  To properly complete Box A, you must
indicate the number of your shares of Raychem common stock for which you are
electing to receive cash or stock or for which you are not making any election.

    Also, in the address box on page 2 above,

    - your name and address must be set forth in the column under the heading
      "Name(s) and address(es) of registered owners(s)," and

                                       11
<PAGE>
    - either (a) the number of each Raychem stock certificate that you are
      surrendering with this document must be written in the column under the
      heading "Certificate number" or (b) if you are using the guarantee of
      delivery procedures, the number of shares represented by your stock
      certificates to be delivered pursuant to such procedures must be written
      in the column under the heading "Number of shares represented by each
      certificate (or covered by a guarantee of delivery)," but no certificate
      number is required.

You will be deemed to have made no election with respect to all shares as to
which you have not indicated an election choice. As set forth above, the
aggregate amount of cash that is payable in the merger, and the aggregate number
of Tyco common shares that are deliverable in the merger are fixed. If the
elections by Raychem stockholders result in an oversubscription of either the
cash consideration or the stock consideration, the exchange agent will follow
the procedures for allocating the merger consideration set forth in Section 1.06
of the merger agreement and described in the proxy statement/prospectus.
Accordingly, there can be no assurance that your election will result in your
receipt of your desired form or mix of merger consideration. However, in all
events, the form and mix of merger consideration you receive will be closer to
your desired choice than if you had made no election. See the proxy
statement/prospectus under the caption "The Merger Agreement--Merger
Consideration--The Proration Rules."

    4.  TERMINATION OF MERGER AGREEMENT.  Consummation of the merger is subject
to the approval of the stockholders of Raychem and to the satisfaction of
certain other conditions. No payments for surrendered Raychem stock certificates
will be made prior to the consummation of the merger, and no payments will be
made if the merger agreement is terminated. If the merger agreement is
terminated, all elections will be void and of no effect, and the exchange agent
will promptly return all Raychem stock previously received by it. In such event,
shares of Raychem common stock held through The Depository Trust Company are
expected to be available for sale or transfer promptly following such
termination. Certificates representing shares of Raychem common stock will be
returned by the exchange agent without charge to the record holder as promptly
as practicable by first class, insured mail.

    5.  NO FRACTIONAL INTERESTS.  No certificate representing a fraction of a
Tyco share will be issued to you. Instead, the exchange agent will remit cash,
without interest, in an amount equal to the product of (A) the average of the
volume weighted average sale prices per Tyco common share on the NYSE for the
three consecutive trading days beginning on the date the merger becomes
effective, and (B) the fractional interest of a Tyco common share to which you
would otherwise be entitled, after taking into account all shares of Raychem
common stock then held of record by you.

    6.  GUARANTEE OF SIGNATURES.  If the merger consideration is to be issued in
your name as inscribed on your surrendered Raychem stock certificate(s), your
signatures on this document need not be guaranteed. If you have completed the
"Special Issuance and Payment Instructions" box so that payment is to be made to
someone other than yourself, your signatures on this document must be guaranteed
by a financial institution, such as most commercial banks, savings and loan
associations and brokerage houses, that is a participant in the Security
Transfer Agent's Medallion Program, the New York Stock Exchange Medallion
Program or the Stock Exchange Medallion Program. Public notaries cannot execute
guarantees of signatures.

    7.  DELIVERY OF THIS DOCUMENT AND YOUR RAYCHEM STOCK CERTIFICATES; GUARANTEE
OF DELIVERY.  You should deliver this document, properly completed and duly
executed, together with your Raychem stock certificate(s) or a guarantee of
their delivery, to the exchange agent at one of the addresses set forth above.
Delivery of the materials will be deemed effective, and risk of loss with
respect thereto will pass, only when such materials are actually received by the
exchange agent. THE METHOD OF DELIVERY OF THIS DOCUMENT, YOUR RAYCHEM STOCK
CERTIFICATES AND ALL OTHER REQUIRED DOCUMENTS IS AT YOUR ELECTION AND RISK. IF
YOU CHOOSE TO SEND THE MATERIALS BY MAIL, IT IS RECOMMENDED THAT THEY BE SENT BY
REGISTERED MAIL, APPROPRIATELY INSURED, WITH RETURN RECEIPT REQUESTED.

                                       12
<PAGE>
    If you wish to make an election but the certificates representing your
shares of Raychem common stock will not be available by the election deadline,
you can use the procedure for guarantee of delivery of your certificates. This
allows you to make your election before the election deadline and subsequently
to deliver your certificates. To use this procedure, the guarantee of delivery
information set forth above must be completed. A guarantee of delivery of stock
certificates must be made by an Eligible Guarantor Institution, generally a
bank, broker, dealer and certain other financial institutions. ANY RAYCHEM STOCK
CERTIFICATES COVERED BY A GUARANTEE OF DELIVERY MUST IN FACT BE DELIVERED TO THE
EXCHANGE AGENT WITHIN THREE NYSE TRADING DAYS AFTER THE DATE THIS DOCUMENT IS
SUBMITTED TO THE EXCHANGE AGENT. FAILURE TO DELIVER SUCH RAYCHEM STOCK
CERTIFICATES WITHIN SUCH THREE DAY PERIOD WILL INVALIDATE ANY ELECTION.

    8.  SHARES HELD IN BOOK-ENTRY FORM.  The exchange agent will request to
establish an account with respect to the Raychem common stock at The Depositary
Trust Company for purposes of receiving shares of Raychem common stock held in
book-entry form owned by holders who wish to make an election. Any financial
institution that is a participant in DTC may make book-entry delivery of Raychem
common stock by causing DTC to transfer such stock into the exchange agent's
account at DTC in accordance with DTC's procedures for transfer. Also, an
Agent's Message, as defined in the next paragraph, and any other required
documents, must be transmitted to and received by the exchange agent prior to
the election deadline.

    The term "Agent's Message" means a message transmitted by DTC to, and
received by, the exchange agent and forming part of the confirmation of
book-entry transfer, which:

    - states that DTC has received an express acknowledgment from the
      participant in DTC transmitting the shares of Raychem common stock,

    - sets forth the election made with respect to such shares, and

    - states that such participant agrees to be bound by the terms of this
      document with respect to such shares.

    9.  SHARES HELD BY NOMINEES, TRUSTEES OR OTHER REPRESENTATIVES.  If you are
a record holder of shares of Raychem common stock and hold such shares as a
nominee, trustee or in another representative or fiduciary capacity, you may
submit one or more Election Form and Transmittal Letters covering the aggregate
number of shares of Raychem common stock held by you for the beneficial owners
for whom you are making an election. You must, however, certify that each
Election Form and Transmittal Letter covers all of the shares of Raychem common
stock held by you for any single beneficial owner. You may be required to
provide the exchange agent with such documents and/or additional certifications,
if requested, in order to satisfy the exchange agent that you hold such shares
of Raychem common stock for a particular beneficial owner. If any shares of
Raychem common stock are not covered by an effective Election Form and
Transmittal Letter, they will be deemed shares for which you have made no
election.

    10.  INADEQUATE SPACE.  If the space provided in this document is
inadequate, the share certificate numbers and the numbers of shares of Raychem
common stock that they represent should be listed on additional sheets and
attached to this document.

    11.  SIGNATURES ON ELECTION FORM AND TRANSMITTAL LETTER, STOCK POWERS AND
ENDORSEMENTS.

    (a) Your signatures must correspond exactly with your name written on the
       face of your Raychem stock certificate(s) without alteration, variation
       or any change whatsoever.

    (b) If the Raychem stock certificates surrendered are held of record by two
       or more joint owners, all such owners must sign this document.

                                       13
<PAGE>
    (c) If any surrendered shares of Raychem common stock are registered in
       different names on several Raychem stock certificate(s), it will be
       necessary to complete, sign and submit as many separate Election Form and
       Transmittal Letters as there are different registrations of Raychem stock
       certificates.

    (d) If you sign this document and you are not the record holder(s) of the
       Raychem stock certificate(s) listed, other than as set forth in paragraph
       (e) below, such certificates must be endorsed or accompanied by
       appropriate stock powers, in either case signed exactly as the name(s) of
       the record holder(s) appear(s) on such certificate(s).

    (e) If you sign this document as a trustee, executor, administrator,
       guardian, attorney-in-fact, officer of a corporation or other person
       acting in a fiduciary or representative capacity and you are not the
       record holder of the accompanying Raychem stock certificates, you must
       indicate the capacity in which you are signing and must submit proper
       evidence of your authority to act.

    12.  SPECIAL ISSUANCE AND PAYMENT INSTRUCTIONS.  If you want the merger
consideration to be delivered in the name of a person or persons that is
different from the person(s) signing this document, you must complete the
"Special Issuance and Payment Instructions" box. If the "Special Issuance and
Payment Instructions" box is completed, the exchange agent will deliver the
merger consideration in the name of, and will mail the merger consideration to,
the person(s) you have indicated at the indicated address. However, the exchange
agent must be provided with satisfactory evidence of the payment of, or
exemption from payment of, any applicable stock transfer taxes.

    13.  SPECIAL DELIVERY INSTRUCTIONS.  If you want the merger consideration to
be delivered in the name of the person(s) signing this document, but to an
address that is different from the address set forth in the address box above,
you must complete the "Special Delivery Instructions" box.

    14.  LOST, STOLEN OR DESTROYED CERTIFICATES.  You cannot make an effective
election without enclosing your Raychem stock certificates with this document or
providing a guarantee of delivery followed within three NYSE trading days by
your certificates. If your Raychem stock certificate(s) have been lost, stolen
or destroyed, you are urged to call Harris Trust and Savings Bank, Raychem's
transfer agent, at (312) 360-5199. The transfer agent will forward additional
documentation which you must complete in order to obtain a replacement stock
certificate. You may be required to post an indemnity bond if so required by
Raychem or its transfer agent.

    15.  MISCELLANEOUS.  Tyco (PA) and the exchange agent have the discretion to
determine whether this document has been properly completed, signed and
submitted or revoked and to disregard immaterial defects in your completion of
this document. The decision of Tyco (PA) or the exchange agent in such matters
shall be conclusive and binding. Tyco (PA) and the exchange agent are not under
any duty to give notification of defects in your completion of this document.

    16.  INFORMATION AND ADDITIONAL COPIES.  Information and additional copies
of this document may be obtained from the information agent by telephoning
toll-free (800) 223-2064.

                           IMPORTANT TAX INFORMATION

    Under federal income tax law, the exchange agent is required to file a
report with the Internal Revenue Service disclosing any cash payments made to
you pursuant to the merger agreement and to impose 31% backup withholding if
required. If the correct certifications on Substitute Form W-9 are not provided,
a $50 penalty may be imposed on you by the IRS and payments made for your shares
of Raychem common stock may be subject to backup withholding of 31% with respect
to any cash consideration to be received pursuant to the merger agreement.
Backup withholding is also required if the IRS notifies you that you are subject
to backup withholding as a result of a failure to report all interest and
dividends.

    In order to avoid backup withholding resulting from a failure to provide a
correct certification, you must, unless an exemption applies, provide the
exchange agent with your correct taxpayer identification number (TIN) on
Substitute Form W-9 as set forth on this document. You must certify under
penalties of perjury that such number is correct and that you are not otherwise
subject to backup withholding.

    The TIN that you must provide is that of the registered holder of the
Raychem common stock. If the Raychem common stock is held in more than one name
or is not registered in the name of the actual holder or if the merger
consideration is to be delivered to another person as provided in the box
entitled "Special Issuance and Payment Instructions," consult the enclosed
guidelines for Certification of Taxpayer Identification Number on Substitute
Form W-9 and your tax advisor for additional guidance on which number to report.
The box in Part 3 of the Substitute Form W-9 should be checked if the
surrendering holder of Raychem common stock has not been issued a TIN and has
applied for a TIN or intends to apply for a TIN in the near future. If the box
in Part 3 is checked and the exchange agent is not provided with a TIN, the
exchange agent will withhold 31% of all cash payments to be paid to the holder
of Raychem common stock pursuant to the merger agreement. Certain persons,
including corporations and non-United States persons are exempt from the
information reporting and backup withholding requirements. If you are a
non-United States person, you may qualify as an exempt recipient by submitting
to the exchange agent a properly completed IRS Form W-8, signed under penalties
of perjury, attesting to your exempt status. Non-United States investors should
consult their tax advisors regarding the need to complete IRS Form W-8 and any
other forms that may be required.

    Backup withholding is not an additional federal income tax. Rather, the
federal income tax liability of a person subject to backup withholding will be
reduced by the amount of tax withheld. If backup withholding results in an
overpayment of taxes, a refund may be obtained from the IRS.

    Please read the enclosed Guidelines for Certification of Taxpayer
Identification Number on Substitute Form W-9 for additional important
information on how to complete the Substitute Form W-9.

    For a summary of the United States federal income tax consequences of the
receipt of the merger consideration, see "Material U.S. Federal Income Tax and
Bermuda Tax Consequences of the Merger" in the proxy statement/prospectus.

the Social Security Administration or the Internal Revenue Service and apply for
a number. United States resident aliens who cannot obtain a social security
number must apply for an ITIN (Individual Taxpayer Identification Number) on

    - A corporation.

    - A financial institution.

    - An organization exempt from tax under section 501(a), an individual

    - An entity registered at all times during the tax year under the Investment
      Company Act of 1940.

    PENALTIES

(1) PENALTY FOR FAILURE TO FURNISH TAXPAYER IDENTIFICATION NUMBER.--If you fail
    to furnish your taxpayer identification number to a payer, you are subject
    to a penalty of $50 for each such failure unless your failure is due to
    reasonable cause and not to willful neglect.

(2) 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.

(3) CRIMINAL PENALTY FOR FALSIFYING INFORMATION.--Willfully falsifying
    certifications or affirmations may subject you to criminal penalties
    including fines and/or imprisonment.

                         MERGER OF RAYCHEM CORPORATION
                                      WITH
                    A SUBSIDIARY OF TYCO INTERNATIONAL LTD.
                      ELECTION FORM AND TRANSMITTAL LETTER

                                                                   July 12, 1999

To the Participants in the Raychem Corporation
Employee Stock Purchase Plan:

    Enclosed for your consideration is a proxy statement/prospectus, dated July
12, 1999, and the related election form and transmittal letter. These documents
are provided to you in connection with the proposed merger of Raychem
Corporation with a subsidiary of Tyco International Ltd. The terms of the merger
are set forth in the Agreement and Plan of Merger and Reorganization, dated as
of May 19, 1999, among Tyco, Tyco International (PA) Inc., a wholly owned
subsidiary of Tyco, and Raychem, which is Annex A to the proxy
statement/prospectus.

    In the merger, Raychem stockholders will receive in the aggregate an amount
of cash equal to $18.50 multiplied by the number of shares of Raychem common
stock outstanding at the time the merger becomes effective (subject to
reduction, as provided in the merger agreement, if there are any dissenting
shares) and a number of Tyco common shares equal to 0.2070 multiplied by the
number of outstanding shares of Raychem common stock. This consideration will be
allocated among Raychem stockholders such that each stockholder will receive
merger consideration with a value of $18.50 plus the value of 0.2070 of a Tyco
common share for each of their shares of Raychem common stock. The value of a
Tyco common share for these purposes is the average of the volume weighted
average sale prices per Tyco share on the New York Stock Exchange for the three
consecutive trading days beginning on the date that the merger becomes
effective.

    Stockholders will have the right to elect to receive their merger
consideration in cash, Tyco common shares or a combination of cash and Tyco
common shares, subject to proration.

    ONLY RAYCHEM STOCKHOLDERS OF RECORD CAN MAKE AN ELECTION. RAYCHEM IS THE
HOLDER OF RECORD OF SHARES FOR YOUR EMPLOYEE STOCK PURCHASE PLAN ACCOUNT, SO
ONLY RAYCHEM CAN MAKE AN ELECTION WITH RESPECT TO YOUR SHARES. THE BLUE GENERAL
STOCKHOLDER ELECTION FORM AND TRANSMITTAL LETTER IS FURNISHED TO YOU FOR YOUR
INFORMATION ONLY AND CANNOT BE USED BY YOU TO MAKE AN ELECTION FOR THE SHARES
THAT RAYCHEM HOLDS FOR YOUR ACCOUNT. YOU MUST USE THE ATTACHED TAN INSTRUCTION
FORM IF YOU WISH RAYCHEM TO MAKE AN ELECTION ON YOUR BEHALF.

    We request instruction whether to have Raychem make an election on your
behalf with respect to any or all of the shares held by Raychem for your
account. If you own any other shares of Raychem, you will be receiving separate
documentation to make your election in respect of those shares.

MATERIALS, PLEASE CALL RAYCHEM EQUITY OPERATIONS AT (650) 361-3925.

                                         WHAT YOU WILL RECEIVE FOR EACH SHARE OF
          ELECTION                                 RAYCHEM COMMON STOCK
- -------------------------------------------------------------------------------------------

                               0.2070 of a Tyco common share
Stock Election...............  a fraction of a Tyco common share having a value of $18.50
                               plus the value of 0.2070 of a Tyco common share
No Election..................  cash, without interest, and/or a fraction of a Tyco common
                               share having a combined value of $18.50 plus the value of
                               0.2070 of a Tyco common share, as determined by the
                               proration rules of the merger agreement
- -------------------------------------------------------------------------------------------
</TABLE>

    Please note:  No fractional Tyco share certificates will be issued in the
                  merger. Any fractional shares in your account after the merger
                  will be paid out in cash.

    2. All elections are subject to the proration procedures set forth in
Section 1.06 of the merger agreement. The proration procedures are described
under the caption "The Merger Agreement-- Merger Consideration--The Proration
Rules" in the proxy statement/prospectus and in General Instruction 3 to the
election form and transmittal letter. IN ADDITION, YOUR CASH AND/OR STOCK
ELECTIONS MAY BE ROUNDED UP OR DOWN AS A RESULT OF THE AGGREGATION WITH THE
OTHER RAYCHEM EMPLOYEE STOCK PURCHASE PLAN PARTICIPANTS.

    3. To be effective, a stockholder's election must be received by the
exchange agent for the merger before the election deadline. This deadline is the
close of business on the last trading day before the date the merger becomes
effective. Tyco and Raychem anticipate that such date will be on or about August
12, 1999, the date of the special meeting of Raychem's stockholders to vote on
the merger. Accordingly, they recommend that stockholders wishing to make an
election assure that their elections are received by the exchange agent no later
than 5:00 p.m. Eastern Time on August 11, 1999. TO ALLOW RAYCHEM TO MAKE AN
ELECTION ON YOUR BEHALF ON A TIMELY BASIS, WE MUST RECEIVE YOUR INSTRUCTIONS NO
LATER THAN 5:00 P.M. EASTERN TIME ON AUGUST 6, 1999.

    4. The right hand corner of the label on the instruction form set forth
below indicates the number of Raychem shares in your account as of July 7, 1999,
if any. If you wish to have Raychem make an election for any or all of these
shares, please complete, sign and return the instruction form to us. It is
important for you to note the following:

    - THE PLAN IS SCHEDULED TO PURCHASE ADDITIONAL SHARES FOR PARTICIPANTS ON OR
      ABOUT JULY 30, 1999. CONSEQUENTLY, THE NUMBER OF SHARES APPEARING ON THE
      LABEL DOES NOT REFLECT ANY ADDITIONAL SHARES THAT YOU MAY RECEIVE ON OR
      ABOUT JULY 30. IF YOU ELECT TO RECEIVE CASH FOR ALL OF YOUR SHARES, YOUR
      ELECTION WILL COVER THE JULY 30 SHARES AS WELL. SIMILARLY, IF YOU ELECT TO
      RECEIVE TYCO SHARES FOR ALL OF YOUR SHARES, YOUR ELECTION WILL COVER THE
      JULY 30 SHARES AS WELL. HOWEVER, IF YOU ELECT TO RECEIVE CASH FOR SOME OF
      YOUR CURRENT SHARES AND ELECT TO RECEIVE TYCO SHARES FOR SOME OF YOUR
      CURRENT SHARES, WE WILL ASSUME THAT YOU ELECT TO RECEIVE TYCO SHARES FOR
      YOUR JULY 30 SHARES UNLESS YOU INSTRUCT US OTHERWISE IN THE SPECIAL
      INSTRUCTIONS SECTION ON THE INSTRUCTION FORM.

    - After you submit your instruction form to us, you may still instruct
      Raychem to sell the shares in your account or make any other transfers out
      of your account at any time on or prior to July 30, 1999, as permitted by
      the terms of the plan. In certain circumstances, this may cause the number
      of shares in your account at the time that Raychem makes the election on
      your behalf to be less

                                       2
<PAGE>
      than the number indicated on the instruction form. If you elect to receive
      either cash for ALL of your shares or Tyco shares for ALL of your shares,
      Raychem will make such election for whatever number of shares is in your
      account at that time. However, if you elect to receive cash for some of
      your shares and elect to receive Tyco shares for some of your shares, and
      your account contains less than the number of shares for which you have
      submitted instructions to us, unless you instruct us otherwise in the
      Special Instructions section, we will first reduce the number of shares
      for which you have not made an election, then reduce the number of shares
      for which you have elected to receive cash, and then reduce the number of
      shares for which you have elected to receive Tyco shares, until the number
      of shares for which you have made an election equals the number of shares
      actually in your account. IN ORDER TO FACILITATE OUR ADMINISTRATIVE
      PROCESSES, THE LAST DAY THAT YOU WILL BE PERMITTED TO INSTRUCT RAYCHEM TO
      SELL THE SHARES IN YOUR ACCOUNT OR MAKE ANY OTHER TRANSFERS OUT OF YOUR
      ACCOUNT WILL BE JULY 30, 1999.

    5. If the merger is not approved by Raychem's stockholders or the merger is
not consummated for any other reason, Raychem's election on your behalf will
have no effect and you will not receive any merger consideration.

    6. To avoid backup withholding, you must also complete the attached
Substitute Form W-9, or, if you are a non-United States person for tax purposes,
the attached Form W-8 or any other required forms. See "Important Tax
Information" immediately following the forms for information regarding these
forms.

    7. This document cannot be used to cast a vote on the merger. If you had
shares of Raychem common stock in your account on July 7, 1999, the record date
for the special meeting, we have provided you with a proxy card with which to
cast your vote.

    You are urged to read the proxy statement/prospectus in its entirety before
completing the instruction form below.

    A tan striped envelope to return your instructions to us is enclosed. Our
address is:

       Harris Trust and Savings Bank

    If you return the instruction form to us but do not indicate an election
with respect to all or part of your shares, we will regard you as making no
election with respect to those shares as to which you have not given us
instructions.

    IF YOU WISH TO MAKE AN ELECTION, PLEASE FORWARD YOUR INSTRUCTIONS TO US NO
LATER THAN 5:00 P.M. EASTERN TIME ON AUGUST 6, 1999 TO ALLOW RAYCHEM TIME TO
MAKE THE ELECTION FOR YOUR SHARES PRIOR TO THE ELECTION DEADLINE.

                           IMPORTANT TAX INFORMATION

    Under federal income tax law, we are required to file a report with the
Internal Revenue Service disclosing any cash payments made to you pursuant to
the merger agreement and to impose 31% backup withholding if required. If the
correct certifications on Substitute Form W-9 are not provided, a $50 penalty
may be imposed on you by the IRS and payments made for your shares of Raychem
common stock may be subject to backup withholding of 31% with respect to any
cash consideration to be received pursuant to the merger agreement. Backup
withholding is also required if the IRS notifies you that you are subject to
backup withholding as a result of a failure to report all interest and
dividends.

    In order to avoid backup withholding resulting from a failure to provide a
correct certification, you must, unless an exemption applies, provide us with
your correct taxpayer identification number (TIN) on Substitute Form W-9 as set
forth on this document. You must certify under penalties of perjury that such
number is correct and that you are not otherwise subject to backup withholding.

    Although Raychem is the registered holder of the Raychem common stock in
your account, the TIN that you must provide is that of the named owner of your
ESPP account. If you are the Raychem employee, in most cases this will be your
Social Security number. If your account is held in more than one name consult
the enclosed guidelines for Certification of Taxpayer Identification Number on
Substitute Form W-9 and your tax advisor for additional guidance on which number
to report. The box in Part 3 of the Substitute Form W-9 should be checked if the
account holder has not been issued a TIN and has applied for a TIN or intends to
apply for a TIN in the near future. If the box in Part 3 is checked and we are
not provided with a TIN, we will withhold 31% of all cash payments to be paid to
the account holder pursuant to the merger agreement. Certain persons, including
corporations and non-United States persons are exempt from the information
reporting and backup withholding requirements. If you are a non-United States
person, you may qualify as an exempt recipient by submitting to us a properly
completed IRS Form W-8, signed under penalties of perjury, attesting to your
exempt status. A Form W-8 is included with this document for the convenience of
participants who are non-United States persons. Non-United States persons should
consult their tax advisors regarding the need to complete, or for assistance
completing, the attached Form W-8 and any other forms that may be required.

    Backup withholding is not an additional federal income tax. Rather, the
federal income tax liability of a person subject to backup withholding will be
reduced by the amount of tax withheld. If backup withholding results in an
overpayment of taxes, a refund may be obtained from the IRS.

    Please read the attached Guidelines for Certification of Taxpayer
Identification Number on Substitute Form W-9 for additional important
information on how to complete the Substitute Form W-9.

    For a summary of the United States federal income tax consequences of the
receipt of the merger consideration, see "Material U.S. Federal Income Tax and
Bermuda Tax Consequences of the Merger" in the proxy statement/prospectus.

                    A SUBSIDIARY OF TYCO INTERNATIONAL LTD.

                      ELECTION FORM AND TRANSMITTAL LETTER

                                                                   July 12, 1999

To Brokers, Dealers, Commercial Banks,
Trust Companies And Other Nominees:

    We have been appointed by Tyco International (PA) Inc., a wholly owned
subsidiary of Tyco International Ltd., to act as exchange agent in connection
with the proposed merger of Raychem Corporation and a subsidiary of Tyco. The
terms of the merger are contained in an Agreement and Plan of Merger and
Reorganization, dated as of May 19, 1999, among Tyco, Tyco (PA) and Raychem. The
stockholders of Raychem will vote on the merger at a meeting scheduled to be
held on August 12, 1999.

    In the merger, Raychem stockholders will receive in the aggregate an amount
of cash equal to $18.50 multiplied by the number of shares of Raychem common
stock outstanding at the time the merger becomes effective (subject to
reduction, as provided in the merger agreement, if there are any dissenting
shares) and a number of Tyco common shares equal to 0.2070 multiplied by the
number of outstanding shares of Raychem common stock. This consideration will be
allocated among Raychem stockholders such that each stockholder will receive
merger consideration with a value of $18.50 plus the value of 0.2070 of a Tyco
common share for each of their shares of Raychem common stock. The value of a
Tyco common share for these purposes is the average of the volume weighted
average sale prices per Tyco share on the New York Stock Exchange for the three
consecutive trading days beginning on the date that the merger is consummated.

    Stockholders will have the right to elect to receive their merger
consideration in cash, Tyco common shares or a combination of cash and Tyco
common shares, subject to proration.

    Only Raychem stockholders of record can make an election. We understand that
you or your nominee may hold of record shares of Raychem common stock for the
account of your clients. Accordingly, we request that you furnish copies of the
enclosed materials to your clients for whose accounts you or your nominee hold
Raychem common stock and request the instruction of your clients as to any
election they wish to make. The enclosed materials include:

        1. Proxy statement/prospectus which contains as Annex A a copy of the
    merger agreement.

        2. The blue election form and transmittal letter to be used by
    stockholders of record of Raychem in making an election.

        3. A printed form of letter which may be sent to your clients for whose
    account you hold shares of Raychem common stock in your name or in the name
    of your nominee with space provided for obtaining your clients' instructions
    for making an election.
