Legal Opinion in connection with an Offer to Exchange (Euro)600,000,000 6 1/8%
Notes due 2007, Tyco International Group S.A. (incorporated as a societe
anonyme with limited liability under the laws of the Grand Duchy of Luxembourg)


Dear Sirs:

   We have acted as legal advisers in the Grand-Duchy of Luxembourg
("Luxembourg") to Tyco International Group S.A. (the "Issuer"), a limited
liability company (societe anonyme) now organized under the laws of Luxembourg
but formerly a company named "Velum Limited" organized under the laws of
Gibraltar which transferred its registered and principal office to Luxembourg
on March 30(th), 1998. We are giving this opinion in connection with the filing
by Tyco International Ltd., a Bermuda company ("Tyco") and the Issuer, with the
United States Securities and Exchange Commission, of Amendment No. 1 to Form S-
4 Registration Statement (File Nos. 333-42128 and 333-42128-01) (the
"Registration Statement") with respect to the Issuer's offer to exchange up to
(Euro)600,000,000 6 1/8% Notes due April 4(th), 2007 for any and all
outstanding 6 1/8% Notes due 2007 (the exchange notes being the "Debt
Securities").

   We have examined copies of the following documents:

     (a) the Registration Statement;

     (b) the minutes of the extraordinary general meeting of shareholders of
  the Issuer held in notarial form before the notary Jean-Joseph Wagner on
  March 30(th), 1998;

     (c) the restated articles of association of the Issuer in a version,
  dated March 30, 1998, published in the Official Gazette (Memorial) C-N(o)
  474 of June 29(th), 1998, an amendment to the articles of association of
  the Issuer by way of a notarial deed dated July 6(th), 1998 and published
  in the Official Gazette (Memorial) C-N(o) 733 of October 10(th), 1998, and
  an amendment to the articles of association of the Issuer by way of a
  notarial deed dated October 22(nd), 1998, published in the Official Gazette
  (Memorial) C-N(o) 44 of January 26(th), 1999, and an amendment to the
  articles of association of the Issuer by way of a notarial deed dated
  December 4(th), 1998, published in the Official Gazette (Memorial) C-N(o)
  144 of March 5(th), 1999, and an amendment to the articles of association
  of the Issuer by way of a notarial deed dated June 14(th), 1999, and
  published in the Official Gazette (Memorial) C-N(o) 692 of September
  16(th), 1999;

     (d) an excerpt from the trade and company register at the district court
  of Luxembourg; and

     (e) the minutes of a meeting of the board of directors of the Issuer
  dated August 26(th), 1999 resolving inter alia the issue of the Debt
  Securities, the entry into any and all contractual documents in connection
  therewith (the "Agreements") and the filing of the Registration Statement.



   For the purposes of this opinion, we have assumed with your consent, and we
have not verified independently, the following:

     (i) the genuineness of all the signatures and documents submitted to us
  as originals and the conformity to the originals thereof of all documents
  in respect of the Debt Securities submitted to us as copies or specimens;

     (ii) the due authorization, execution and delivery of all documents in
  respect of the Debt Securities by all the parties thereto (other than the
  Issuer), as well as the power, authority and legal right of all the parties
  thereto (other than the Issuer) to enter into, execute, deliver and perform
  their respective obligations thereunder, and compliance with all applicable
  laws and regulations, other than Luxembourg law;

     (iii) that all authorizations and consents of any country other than
  Luxembourg which may be required in connection with the execution, delivery
  and performance of the Agreements and other documents, including the
  Registration Statement, in respect of the issue of the Debt Securities have
  been or will be obtained;

     (iv) the validity and enforceability of the Agreements and other
  documents in respect of the Debt Securities under their governing laws
  (other than the laws of Luxembourg);

     (v) that the Debt Securities will not be the subject of a public
  offering in Luxembourg, unless the relevant requirements of Luxembourg law
  concerning public offerings of securities have been fulfilled; and

     (vi) that there are no provisions of the laws of any jurisdiction
  outside Luxembourg which would have any negative impact on the opinions we
  express in this legal opinion.

   Subject to the assumptions made above and the qualifications set forth
below, we are of the opinion as at the date hereof that:

     1. The Issuer is a limited liability company validly organized and
  existing under the laws of Luxembourg and has all requisite corporate power
  and authority to issue the Debt Securities.

     2. All necessary action required to be taken by the Issuer pursuant to
  the laws of Luxembourg has been taken by or on behalf of the Issuer and all
  the necessary authorizations and approvals of government authorities in
  Luxembourg have been duly obtained for the issue by the Issuer of the Debt
  Securities.

     3. No filing with, or authorization, approval, consent, license, order,
  registration, qualification or decree of, any court or government authority
  or agency in Luxembourg is necessary or required to be made or obtained by
  Tyco or the Issuer in connection with the issue by the Issuer of the Debt
  Securities.

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

   The above opinions are subject to the following qualifications:

     a) Although this is rarely done in practice, if any or all Agreements or
  the Registration Statement were produced in Luxembourg proceedings or in
  front of a Luxembourg official authority, the court could order the
  registration thereof, in which case an ad valorem tax would be payable at
  the rate of 0.24 per cent., unless production was made in an enforceability
  claim under the provisions of the European Convention of Jurisdiction and
  Enforcement or Judgements in Civil and Commercial matters signed at
  Brussels on September 27(th), 1968, as amended.

     b) This opinion is limited to matters of Luxembourg law only and we
  express no opinion other than with respect to Luxembourg law under the
  assumptions and reservations made hereunder.


                                       2


     c) This opinion is as of this date and we undertake no obligation to
  update it or advise of changes hereafter occurring. We express no opinion
  as to any matters other than those expressly set forth herein, and no
  opinion is, or may be, implied or inferred herefrom.

   It should be noted that there are always irreconcilable differences between
languages making it impossible to guarantee a totally accurate translation or
interpretation. In particular, there are always some legal concepts which exist
in one jurisdiction and not in another, and in those cases it is bound to be
difficult to provide a completely satisfactory translation or interpretation
because the vocabulary is missing from the language. We accept no
responsibility for omissions or inaccuracies to the extent that any are
attributable to such factors.

   This opinion shall be construed in accordance with Luxembourg law and
Luxembourg legal concepts are expressed in English terms and not in their
original French terms. The concepts concerned may not be identical to the
concepts described by the same English terms as they exist under the laws of
other jurisdictions.

   This opinion may, therefore, only be relied upon under the express condition
that any issues of interpretation arising thereunder will be governed by
Luxembourg law and be brought before a Luxembourg court. Nothing in this
opinion should be taken as expressing an opinion in respect of any
representations or warranties, or other information, contained in the
Prospectus included in the Registration Statement or any other document
examined in connection with the opinion except as expressly confirmed herein.

   We hereby consent to the inclusion of the opinion as an exhibit to the
Registration Statement. We also consent to the reference to our firm under the
caption "Legal Matters" in the Prospectus included as part of the Registration
Statement.

Yours faithfully,

Beghin & Feider
