                                  THE COMPANY
 
    Tyco is a diversified manufacturing and service company that, through its
subsidiaries:
 
    - designs, manufactures and distributes electrical and electronic components
      and designs, manufactures, installs and services undersea cable
      communication systems;
 
    - designs, manufactures and distributes disposable medical supplies and
      other specialty products, and conducts vehicle auctions and related
      services;
 
    - designs, manufactures, installs and services fire detection and
      suppression systems and installs, monitors and maintains electronic
      security systems; and
 
    - designs, manufactures and distributes flow control products.
 
    Tyco's strategy is to be the low-cost, high quality producer and provider in
each of its markets. It promotes its leadership position by investing in
existing businesses, developing new markets and acquiring complementary
businesses and products. Combining the strengths of its existing operations and
its business acquisitions, Tyco seeks to enhance shareholder value through
increased earnings per share and strong cash flows.
 
    On July 2, 1997, a wholly-owned subsidiary of what was formerly called ADT
Limited merged with Tyco International Ltd., a Massachusetts corporation. Upon
consummation of the merger, ADT, the continuing public company, changed its name
to Tyco International Ltd.
 
    Tyco's registered and principal executive offices are located at The Gibbons
Building, 10 Queen Street, Suite 301, Hamilton HM 11, Bermuda, and its telephone
number is (441) 292-8674. The executive offices of Tyco's principal United
States subsidiary, Tyco International (US) Inc., are located at One Tyco Park,
Exeter, New Hampshire 03833, and its telephone number is (603) 778-9700.
 
                              CURRENT DEVELOPMENTS
 
PENDING ACQUISITION OF AMP
 
    On November 22, 1998, a subsidiary of Tyco entered into a definitive merger
agreement for the acquisition of AMP Incorporated. It is estimated that Tyco
will issue up to approximately 186.0 million common shares for delivery by its
subsidiary to the former shareholders of AMP in the merger. AMP designs,
manufactures and markets electronic, electrical and electro-optic connection
devices and associated application tools and machines. AMP had annual revenues
of approximately $5.5 billion in 1998.
 
    The acquisition of AMP, which will be accounted for as a pooling of
interests, has been structured so that AMP shareholders will receive for each of
their shares of AMP common stock a fraction of a Tyco common share valued
between $51.00 and $55.95. The fraction will be determined based on the average
of the daily weighted averages of the trading price of Tyco common shares on the
New York Stock Exchange for the 15 trading days ending on March 26, 1999, which
is the fourth trading day prior to the date of the special meeting of AMP
shareholders to vote on the merger.
 
    Tyco has identified certain risks in connection with the AMP acquisition,
including:
 
    - The benefits to Tyco and its shareholders of the merger are predicated on
      the assumption that the merger will be accretive to Tyco's earnings per
      share, but this will only be the case if Tyco can efficiently integrate
      AMP with Tyco's existing operations. On a pro forma basis, which combines
      the financial results of the two companies based upon their historical
      performance, the merger is not accretive to earnings per share. Tyco
      expects that the merger will be accretive if it can realize cost savings
      and synergies through the combination of the two companies. In this
      regard, Tyco's management believes that it can continue to implement and
      enhance AMP's profit
 
                                       2
<PAGE>
      improvement plan, which involves staff reductions, plant closings and
      consolidations and other cost cutting activities. Tyco has in the past
      been successful in integrating prior acquisitions and realizing
      anticipated earnings benefits. However, with facilities in 53 countries
      and approximately 48,500 employees worldwide, AMP is substantially larger
      than the largest company previously integrated by Tyco's management. It is
      possible that Tyco will not be able to integrate AMP in a manner that
      achieves the desired savings and other benefits. Also, it may take longer
      to achieve these savings and other benefits than anticipated by Tyco's
      management. If so, Tyco's earnings-per-share performance, which is driven
      in part by the success of its acquisitions, is likely to suffer.
 
    - The AMP acquisition could significantly increase the effects of the
      downturn in the Asian economy on Tyco. Historically, only 3% of Tyco's
      revenues were attributable to Tyco's Asian operations, as opposed to 20%
      of AMP's revenues. The effect of the downturn has been more pronounced on
      AMP because of AMP's greater dependence on Asian business. Tyco cannot
      predict how long the economic downturn in Asia will persist.
 
   
    The consummation of the AMP transaction is contingent upon approval by the
AMP shareholders of the merger, approval by the Tyco shareholders of the
issuance of the Tyco common shares to be delivered in connection with the merger
and other customary conditions. Special meetings of the shareholders of Tyco and
AMP to consider these matters have been scheduled for April 1, 1999. Tyco
expects that the closing of the AMP transaction will occur shortly after receipt
of the required shareholder consents. There is no assurance that the AMP
acquisition will be consummated.
    
 
   
    AMP is subject to the informational requirements of the Exchange Act, and in
accordance with the Exchange Act, files reports, proxy statements and other
information with the SEC. Tyco has filed a registration statement on Form S-4
with the SEC in respect of the AMP transaction which has been declared
effective.
    
 
                                USE OF PROCEEDS
 
    All net proceeds from the sale of the common shares offered hereby will go
to the selling shareholders. Tyco will not receive any of the proceeds from the
sale of the common shares by the selling shareholders.
 
                              SELLING SHAREHOLDERS
 
    The selling shareholders are former stockholders or optionholders of
Progressive Angioplasty Systems, Inc. PAS was acquired by United States Surgical
Corporation under the terms of an agreement and plan of merger dated February 4,
1997 and amended as of August 6, 1997. Pursuant to this merger agreement, US
Surgical issued shares of its common stock to the PAS stockholders with an
aggregate value of approximately $73.8 million. US Surgical also agreed to
assume the outstanding PAS stock options, which became options to acquire US
Surgical common stock.
 
   
    In addition, the merger agreement between US Surgical and PAS provided that
the former PAS stockholders, and former PAS optionholders following exercise of
their options, would be entitled to receive, without payment of any additional
consideration, in the aggregate:
    
 
        1. US Surgical common stock with a value of up to $25 million, some of
    which was paid upon closing of the merger, if certain milestones related to
    the business of PAS were achieved. This stock is referred to as "milestone
    consideration."
 
        2. US Surgical common stock with a value of up to $50 million, some of
    which was paid upon closing of the merger, if specified net sales of
    catheters, stents and radiation products embodying PAS's proprietary
    technology were achieved at various times through December 31, 2003. This
    stock is referred to as "earn out consideration."
 
                                       3
<PAGE>
   
    On October 1, 1998, Tyco acquired US Surgical. Under the terms of the
agreement and plan of merger between Tyco and US Surgical, Tyco agreed to assume
the obligation of US Surgical to deliver additional stock to the former PAS
stockholders and optionholders, except that Tyco common shares would be
delivered rather than shares of US Surgical common stock. The common shares
offered by this document and listed below are shares that were issued to the
former PAS stockholders or are issuable to former PAS optionholders as a result
of the occurrence of certain milestone events or as earn out consideration for
sales of products during the period just prior to the merger of Tyco and US
Surgical through January 1, 1999. Additional common shares may be offered in the
event that
    
 
   
    - other former PAS optionholders who are entitled to receive milestone
      consideration or earn out consideration upon exercise of their options
      exercise such options;
    
 
    - additional milestone consideration or earn out consideration becomes
      payable to former PAS stockholders and optionholders; or
 
   
    - additional common shares are issued to the selling shareholders by way of
      adjustment to milestone consideration or earn out consideration they have
      previously received,
    
 
   
and the recipients of such additional shares elect to have their additional
shares offered. In addition, certain former PAS stockholders and optionholders
that have received milestone consideration and earn out consideration but have
not elected to have their shares offered may elect to do so in the future. If
any additional common shares are to be offered, this document will be
appropriately supplemented or amended.
    
 
   
    On February 19, 1999, US Surgical commenced an action in the United States
District Court for the District of Delaware against one of the selling
shareholders. (United States Surgical Corporation v. Frank Litvack, Civil Action
No. 99-088). The action seeks a declaratory judgment that the terms of the
merger agreement between US Surgical and PAS do not prohibit US Surgical from
discontinuing any business or operations conducted by PAS prior to its merger
with US Surgical or give any right or remedy to the former PAS stockholders and
optionholders as a result of such discontinuance.

                              PLAN OF DISTRIBUTION
    
 
    The common shares may be sold from time to time by the selling shareholders
or by pledgees or donees of the selling shareholders. Such sales may be made on
the New York Stock Exchange or other exchanges or in the over-the-counter
market, or otherwise, at prices and on terms then prevailing or at prices
related to the then current market price, or in negotiated transactions at
negotiated prices. The manner in which sales of common shares can be made
include:
 
    - ordinary brokerage transactions;
 
    - transactions in which a broker solicits purchasers;
 
    - block trades;
 
    - purchases by a broker or dealer as principal and resale by such broker
      dealer for its account;
 
    - put or call option transactions relating to the common shares; or
 
    - transactions directly between seller and purchaser without a
      broker-dealer.
 
Common shares that qualify for sale in accordance with Rule 144 under the
Securities Act may be sold under Rule 144 rather than pursuant to this document.
 
    Brokers or dealers involved in the sale may receive commissions or discounts
in connection with such sale in amounts to be negotiated. A broker or dealer
that acts as agent for a purchaser of common shares would be paid by the
purchaser. The selling shareholders and any broker-dealers who act in connection
with the sale of the common shares that are offered by this document may be
deemed underwriters for purposes of the Securities Act. Any commissions
broker-dealers receive and profits they make on resale might be deemed
underwriting discounts and commissions.
 
    Tyco will pay all expenses of registration of the common shares offered
hereby, other than commissions, discounts and fees of brokers, dealers or
agents.
 
                                 LEGAL MATTERS

hereby have been passed upon for Tyco by Appleby, Spurling & Kempe, Hamilton,

(as amended) prohibits such indemnification against any liability arising out of
fraud or dishonesty of the director or officer. However, such section permits
Tyco to indemnify a director or officer against any liability incurred by him in
defending any proceedings, whether civil or criminal, in which judgment is given
in his favor or in which he is acquitted or when other similar relief is granted
to him.
 
    Tyco maintains $75 million of insurance to reimburse the directors and
officers of Tyco and its subsidiaries for charges and expenses incurred by them
for wrongful acts claimed against them by reason of their being or having been
directors or officers of Tyco and or any of its subsidiaries. Such insurance
specifically excludes reimbursement of any director or officer for any charge or
expense incurred in connection with various designated matters, including libel
or slander, illegally obtained personal profits, profits recovered by Tyco
pursuant to Section 16(b) of the Exchange Act and deliberate dishonesty.

ITEM 17. UNDERTAKINGS
 
    Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the foregoing provisions, or otherwise, the Registrant
has been advised that in the opinion of the Securities and Exchange Commission
such indemnification is against public policy as expressed in the Act and is,
therefore, unenforceable. In the event that a claim for indemnification against
such liabilities (other than the payment by the Registrant of expenses incurred
or paid by a director, officer or controlling person of the Registrant in the
successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the Registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Securities Act and will be governed by the final
adjudication of such issue.
 
    The undersigned Registrant hereby undertakes:
 
        (1) To file, during any period in which offers or sales are being made,
    a post-effective amendment to this registration statement:
 
           i. To include any prospectus required by Section 10(a)(3) of the
       Securities Act;
 
                                      II-2
<PAGE>
           ii. To reflect in the prospectus any facts or events arising after
       the effective date of the registration statement (or the most recent
       post-effective amendment thereof) which, individually or in the
       aggregate, represent a fundamental change in the information set forth in
       the registration statement. Notwithstanding the foregoing, any increase
       or decrease in volume of securities offered (if the total dollar value of
       securities offered would not exceed that which was registered) and any
       deviation from the maximum aggregate offering price may be reflected in
       the form of prospectus filed with the SEC pursuant to Rule 424(b) under
       the Securities Act, if in the aggregate, the changes in volume and price
       represent no more than a 20% change in the maximum aggregate offering
       price set forth in the "Calculation of Registration Fee" table in the
       effective registration statement; and
 
           iii. To include any material information with respect to the plan of
       distribution not previously disclosed in the registration statement or
       any material change to such information in the registration statement;
 
           PROVIDED, HOWEVER, that clauses (i) and (ii) do not apply if the
           registration statement is on Form S-3, Form S-8 or Form F-3, and the
           information required to be included in a post-effective amendment by
           such clauses is contained in periodic reports filed with or furnished
           to the Commission by the Registrant pursuant to Section 13 or 15(d)
           of the Securities Exchange Act of 1934 that are incorporated by
           reference in the registration statement;
 
        (2) That, for the purpose of determining any liability under the
    Securities Act, each such post-effective amendment shall be deemed to be a
    new registration statement relating to the securities offered therein, and
    the offering of such securities at that time shall be deemed to be the
    initial BONA FIDE offering thereof;
 
        (3) To remove from registration by means of a post-effective amendment
    any of the securities being registered which remain unsold at the
    termination of the offering.
 
    The undersigned Registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act, each filing of the
Registrant's annual report pursuant to Section 13(a) or 15(d) of the Securities
Exchange Act of 1934 (and, where applicable, each filing of an employee benefit
plan's annual report pursuant to Section 15(d) of the Securities Exchange Act of
1934) that is incorporated by reference in the registration statement shall be
deemed to be a new registration statement relating to the securities offered
therein, and the offering of such securities at that time shall be deemed to be
the initial BONA FIDE offering thereof.
 
    The undersigned Registration hereby undertakes that: (1) for purposes of
determining any liability under the Securities Act of 1933, the information
omitted from the form of prospectus filed as part of this registration statement
in reliance upon Rule 430A and contained in a form of prospectus filed by the
Registrant pursuant to Rule 424(b)(1) or (4) or 497(h) under the Securities Act
shall be deemed to be part of this registration statement as of the time it was
declared effective; and (2) for the purpose of determining any liability under
the Securities Act of 1933, each post-effective amendment that contains a form
of prospectus shall be deemed to be a new registration statement relating to the
securities offered therein, and the offering of such securities at that time
shall be deemed to be the initial BONA FIDE offering thereof.

Tyco International Ltd.
The Gibbons Building
10 Queen Street
Hamilton HM 11
Bermuda



Dear Sirs

REGISTRATION STATEMENT ON FORM S-3

We have acted as attorneys in Bermuda for Tyco International Ltd., a Bermuda
limited liability company ("Tyco"), in connection with its filing with the
United States Securities and Exchange Commission of a Registration Statement on
Form S-3, File No. 333-73223, as amended by Amendment No. 1 thereto (together
the "Registration Statement"), with respect to 300,000 of the Company's common
shares, US$0.20 par value per share (the "Shares"), issued to the selling
shareholders named in the Registration Statement (the "Selling Shareholders")
under the Securities Act of 1933, as amended, of the United States.

For the purposes of this opinion we have examined and relied upon the documents
listed which, in some cases, are also defined in the Schedule to this opinion,
(the "Documents").

Unless otherwise defined herein terms defined in the Registration Statement have
the same meanings when used in this opinion.

ASSUMPTIONS

We have assumed:

(i) that there is no provision of the law, regulation or public policy of any
jurisdiction, other than Bermuda, which would have a material effect on any of
the opinions herein expressed;

(ii) that all representations and factual statements appearing in the
Registration Statement are true, accurate and complete in all material respects;

(iii) the genuineness of all signatures on the Documents;

<PAGE>

(iv) the authenticity, accuracy and completeness of all documents submitted to
us as originals and the conformity to authentic original documents, of all
documents produced to us as certified, conformed, notarised or photostatic
copies;

(v) that options held by the Selling Shareholders to acquire US Surgical common
stock pursuant to the merger agreement between US Surgical and PAS (the "PAS
Merger") have been or will be validly exercised in accordance with their terms;

(vi) that pursuant to the PAS Merger US Surgical received valid consideration 
for the US Surgical common stock issued or to be issued to the Selling 
Shareholders, and that such consideration represents not less than the par 
value of the Shares issued, or to be issued, by Tyco in satisfaction of the 
obligation of US Surgical to the Selling Shareholders assumed by Tyco 
pursuant to the terms of the agreement and plan of merger between Tyco and US 
Surgical;

(vii) that the information disclosed by our Searches has not been materially
altered and that the Searches did not fail to disclose any material information
which had been delivered for filing or registration, but was not disclosed or
did not appear on the public file at the time of the Searches;

(viii) that the Signature Pages evidence the approval of all of the Directors of
Tyco of all matters relating to Tyco set out in the Registration Statement;

(ix) that the Resolutions are in full force and effect and have not been
rescinded, either in whole or in part and accurately record the resolutions
passed by the Board of Directors of the Company at a meeting which was duly
convened and at which a duly constituted quorum was present and voting
throughout; and

(x) that any resolutions of the Board of Directors of Tyco, being similar to the
Resolutions, in respect of the authorisation of the issue of the balance of the
Shares will be adopted at a meeting which will have been validly convened and
at which a duly constituted quorum will be present and voting throughout and
such resolutions will be in full force and effect and will not have been
rescinded in whole or in part at the time that such shares are issued.

OPINION

Based on and subject to the foregoing, subject to the reservations set out
below, and to any matters not disclosed to us, we are of the opinion that:

(1)  Tyco has been duly incorporated as a limited liability company and is
     validly existing and in good standing under the laws of Bermuda and has all
     requisite corporate power and authority to issue the Shares.

(2)  When duly issued pursuant to the Resolutions or similar duly adopted Board
     resolutions all necessary action required to be taken by Tyco pursuant to 
     Bermuda law will have been taken by 

<PAGE>

     or on behalf of Tyco and all the necessary authorisations and approvals of
     Governmental authorities in Bermuda have been duly obtained for the issue 
     by Tyco of the Shares.

(3)  When duly issued pursuant to the Resolutions or similar duly adopted 
     Board resolutions and in the circumstances referred to or summarised 
     under the caption "Selling Shareholder" in the Registration Statement 
     the Shares will be (or, to the extent heretofore issued, are) validly
     issued, fully paid and non-assessable shares in the capital of Tyco.

(4)  There are no taxes, duties or other charges payable to or chargeable by the
     Government of Bermuda, or any authority or agency thereof, in respect of
     the issue of the Securities.

RESERVATIONS

We have the following reservations:-

(a)  We express no opinion as to any other law other than Bermuda law and none
     of the opinions expressed herein relates to compliance with or matters
     governed by the laws of any jurisdiction except Bermuda. This opinion is
     limited to Bermuda law as applied by the Courts of Bermuda as at the date
     hereof.

(b)  In paragraph (1) above, the term "good standing" means that the Company has
     neither failed to make any filing with any Bermuda governmental authority
     nor to pay any Bermuda government fee or tax, which might make it liable to
     be struck off the Registrar of Companies and thereby cease to exist under
     the laws of Bermuda.

(c)  Any reference in this opinion to shares being "non-assessable" shall mean,
     in relation to fully paid shares of Tyco and subject to any contrary
     provision in any agreement in writing between such company and the holder
     of such shares, that no shareholder shall be bound by an alteration to the
     Memorandum of Association or Bye-laws of Tyco after the date on which he
     became a shareholder, if and so far as the alteration requires him to take,
     or subscribe for additional shares, or in any way increases his liability
