                              CORPORATE GOVERNANCE

    We learned of instances of breakdowns of certain internal controls during
fiscal 2002. This began in January 2002, when our Board of Directors (sometimes
referred to herein as our "Board") learned of an unauthorized payment to our
former Lead Director, Frank E. Walsh, Jr., and eventually led to the Board
replacing our former senior corporate management team. These instances included
abuse of our employee relocation loan programs, unapproved bonuses, attempted
unauthorized credits to employee loans, undisclosed compensation arrangements,
unreported perquisites, self-dealing transactions and other misuses of corporate
trust, and have been widely reported in the press.

    Our Board retained the law firm of Boies, Schiller & Flexner LLP in
April 2002 to conduct an investigation. The scope of the investigation consisted
of a review and analysis of transactions between and among Tyco and its
subsidiaries and our directors and officers. The findings of the first phase
(Phase 1) were reported on September 17, 2002 in a Current Report on Form 8-K.

    In connection with the Phase 1 findings and at the direction of the Board
and our new Chief Executive Officer, the investigation was expanded to a second
phase (Phase 2), which involved a more comprehensive review of Tyco's accounting
and financial reporting. The scope of the Phase 2 review included an examination
of Tyco's reported revenues, profits, cash flow, internal auditing and control
procedures, use of reserves, and non-recurring charges, as well as corporate
governance issues such as the personal use of corporate assets and the use of
corporate funds to pay personal expenses, and employee loan and loan forgiveness
programs. Phase 2 of the investigation was completed by the Boies firm in late
December 2002. These findings were reported on December 30, 2002 in a Current
Report on Form 8-K.

    Additionally, our new senior management team in conjunction with our Board
reviewed overall company policies and procedures in areas that were viewed as
important. Specific areas of focus included acquisition accounting,
restructuring, financial and legal controls, reserve utilization, incentive
compensation and a number of other areas relevant to our financial statements.
New senior management determined that Tyco's existing policies and standards of
approval needed substantial improvement and found that there were instances in
which documentation of important financial reporting matters was substandard;
there had been limited review of bonuses and incentive compensation across Tyco;
and the manner in which former senior management managed Tyco did not reflect a
commitment to sound corporate governance nor the processes required to ensure
the highest standards of financial integrity and accounting rigor to which the
new senior management team and our Board is committed and our shareholders
deserve.

    Over the past several months, Tyco has replaced its former senior corporate
management team with entirely new members and the Board determined not to
nominate or support for re-election any of the current members of the Board who
were Board members prior to the appointment of Tyco's new Chairman and Chief
Executive Officer in July 2002. John A. Krol, our new lead director, joined the
Board in August 2002. Four new directors, Jerome B. York, Mackey J. McDonald,
George W. Buckley and Bruce S. Gordon, joined the Board in recent months. To
assist and provide any necessary continuity to the new Board that will be
elected at the Annual General Meeting, two of the members of the Board who were
members prior to the appointment of our new Chairman and Chief Executive Officer
will serve as advisors to the Board and will be invited to attend meetings of
the Board and its Committees as requested by the Board, but will not be entitled
to vote on any matters presented for a vote at any such meetings.

    Although a framework has been put in place to materially improve the control
structure of Tyco, it will take some time to realize all of the benefits from
our initiatives. Our Board and new senior corporate management are committed to
improving the state of our internal controls, corporate governance and financial
reporting. In this regard, new corporate governance principles have been
prepared and circulated, along with revised committee charters, to Tyco's Board
for their consideration and discussion and the position of Senior Vice President
of Corporate Governance has been established and staffed with a senior
executive. The full text of our corporate governance principles, along with all
our committee charters and

                                       5

our new employee code of conduct will be posted on Tyco's website at
WWW.TYCO.COM once they are adopted. A summary of the corporate governance
principles under consideration by Tyco's Board, as well as information about
Tyco's Board committees, is presented below. The charter of the audit committee
is attached as Exhibit A to this Proxy Statement.

CORPORATE GOVERNANCE PRINCIPLES

MISSION OF THE BOARD OF DIRECTORS

    The business of Tyco is managed under the direction of the Board. The
mission of the Board is to promote the long-term health of Tyco and grow
shareholder value.

BOARD RESPONSIBILITIES

    The Board's responsibilities include:

    - Recommending candidates to the shareholders for election to the Board.

    - Selecting, monitoring, evaluating, compensating and, if necessary,
      replacing, the chief executive officer and other senior executives, and
      seeing that robust management development and succession plans are
      maintained.

    - Overseeing compliance with laws and regulations and setting an ethical
      "tone at the top."

    - Appraising Tyco's major risks and its risk management and seeing that
      control procedures are in place.

    - Reviewing and approving management's strategic and business plans.

    - Reviewing and approving financial plans, objectives and actions, including
      significant capital allocations and expenditures.

    - Monitoring management performance of its plans and objectives.

    - Assessing its own effectiveness.

BOARD ORGANIZATION

    The Board consists of a substantial majority of independent directors who
meet a stringent definition of independence. The independent directors of the
Board, acting in executive session, elect a lead director to serve as chair of
the Corporate Governance and Nominating Committee. The lead director chairs an
executive session of the independent directors at each formal Board meeting. The
Board also maintains two other standing committees--Audit and Compensation. All
three committees are entirely composed of independent directors. Assignments to,
and chairs of, the committees are recommended by the Corporate Governance and
Nominating Committee and selected by the Board. All committees report on their
activities to the Board.

BOARD OPERATION

    The Board normally meets six times annually and committee meetings are
normally held in conjunction with Board meetings. The Board and committee chairs
are responsible for conducting meetings and informal consultations in a fashion
that encourages informed, meaningful and probing deliberations. Directors
receive the agenda and materials in advance and may ask for additional
information from, or meet with, senior managers at any time. Strategic planning
and succession planning sessions are held annually at regular Board meetings.

                                       6

BOARD ADVISORS

    The Board and its committees (consistent with their respective charters) may
retain their own advisors as they determine necessary to carry out their
responsibilities.

BOARD EVALUATION

    The Corporate Governance and Nominating Committee coordinates an annual
evaluation process by the directors of the Board's performance and procedures,
including evaluation of individual directors. The three standing committees each
conduct an annual evaluation of their performance and procedures, including the
adequacy of their charters.

BOARD COMPENSATION AND SHARE OWNERSHIP

    Director compensation consists of cash and, for non-employee directors, an
award of stock options. The stock option component reflects the Board's belief
that director compensation should be tied to the performance of Tyco's common
shares. The Compensation Committee, in collaboration with the Corporate
Governance and Nominating Committee, periodically reviews the directors'
compensation and recommends changes as appropriate.

COMMITTEES OF THE BOARD OF DIRECTORS

    The Board maintains three standing committees: Audit, Compensation, and
Corporate Governance and Nominating. The independent directors of the Board,
acting in executive session, elect a lead director to serve as chair of the
Corporate Governance and Nominating Committee. The lead director chairs an
executive session of the independent directors at each formal Board meeting.
Assignments to, and chairs of, the committees are recommended by the Corporate
Governance and Nominating Committee and selected by the Board. All committees
report on their activities to the Board.

    AUDIT COMMITTEE.  The Audit Committee monitors the integrity of Tyco's
financial statements, the independence and qualifications of the independent
auditors, the performance of Tyco's internal auditors as well as the independent
auditors, Tyco's compliance with legal and regulatory requirements and the
effectiveness of Tyco's internal controls. The Audit Committee is also
responsible for retaining, evaluating, and, if appropriate, recommending the
termination of Tyco's independent auditors. The Audit Committee held twelve (12)
formal meetings during fiscal 2002 in addition to the numerous and extensive
informal meetings and teleconferences that the Audit Committee held since the
Board and the Audit Committee learned of instances of breakdowns of certain
internal controls in January 2002. See "Corporate Governance." If the nominees
for director are elected at the Annual General Meeting, Mr. O'Neill and Ms.
Wijnberg will join Mr. York (who was elected Chairman in January 2003) on the
Audit Committee.

    COMPENSATION COMMITTEE.  The Compensation Committee reviews and approves
compensation and benefits policies and objectives, determines whether Tyco's
officers, directors and employees are compensated according to these objectives,
and carries out the Board's responsibilities relating to the compensation of
Tyco's executives. The Compensation Committee held seventeen (17) meetings
during fiscal 2002. If the nominees for director are elected at the Annual
General Meeting, Mr. Blair will join Messrs. Buckley and McDonald (who were
elected to the Compensation Committee in January 2003) on the Compensation
Committee, with Mr. McDonald serving as Chairman.

    CORPORATE GOVERNANCE AND NOMINATING COMMITTEE.  The Corporate Governance and
Nominating Committee is responsible for identifying individuals qualified to
become Board members, recommending to the Board the director nominees for the
annual general meeting of shareholders, developing and recommending to the Board
a set of corporate governance principles, and playing a general leadership role
in Tyco's corporate governance. The Committee will consider nominations
submitted by shareholders. To recommend a nominee, a shareholder should write to
Tyco's Secretary at Tyco's registered address in Pembroke, Bermuda. Any such
recommendation must include the name and address of the candidate, a brief
biographical description or statement of the qualifications of the candidate and
the candidate's signed consent to serve as a director if elected. The Corporate
Governance and Nominating Committee held three (3) meetings during fiscal 2002.
If the nominees for director are elected at the Annual General Meeting, the
members of the Corporate Governance and Nominating Committee will continue to be
Messrs. Gordon and Krol, with Mr. Krol serving as Chairman.

AUDIT COMMITTEE REPORT

    The Audit Committee of the Board was composed of three independent directors
during fiscal 2002. In January 2002, the Audit Committee, along with other Board
members, learned of instances of breakdowns of certain internal controls. This
began when the Board learned of an unauthorized payment to Tyco's former lead
director, Frank E. Walsh, Jr., that was purportedly made for his assistance in
arranging Tyco's acquisition of The CIT Group, Inc. These instances included
abuse of Tyco's employee relocation programs, unapproved bonuses, attempted
unauthorized credits to employee loans, undisclosed compensation arrangements,
unreported perquisites, self-dealing transactions and other misuses of corporate
trust, and have been widely reported in the press. Tyco's former Chief Executive
Officer resigned on June 3, 2002 and the former Chairman of the Audit Committee
replaced him on an interim basis. Tyco's former Chief Corporate Counsel was
dismissed on June 10, 2002 and the former Chief Financial Officer

                                       10
<Page>
resigned on August 1, 2002. These members of Tyco's former senior corporate
management team have each been indicted by the State of New York for violations
of criminal law. In addition, Mr. Walsh was indicted by the State of New York
for violations of criminal law and, in December 2002, pled guilty to a felony
violation of New York law, and, as part of such plea, agreed to return the
unauthorized payment.

    The Board, in conjunction with the Audit Committee, retained the law firm of
Boies, Schiller & Flexner LLP to conduct an investigation consisting of a review
and analysis of transactions between and among Tyco and its subsidiaries and its
directors and officers. The Board, in conjunction with the Audit Committee and
Tyco's new senior corporate management team, subsequently expanded the scope of
the investigation to include a comprehensive review of Tyco's reported revenues,
profits, cash flow, internal auditing and control procedures, use of reserves,
and non-recurring charges, as well as corporate governance issues such as the
personal use of corporate assets and the use of corporate funds to pay personal
expenses, and employee loan and loan forgiveness programs. The two phases of
this investigation were reported on September 17, 2002 and December 30, 2002,
respectively, in Current Reports on Form 8-K.

    The Audit Committee operates under a charter approved by the Board in
January 2003, which is attached to this Proxy Statement as Exhibit A. As more
fully described in its charter, the Audit Committee reviews Tyco's financial
reporting process on behalf of the Board. Management has the primary
responsibility for the financial statements and the reporting process. Tyco's
independent auditors are responsible for performing an audit of Tyco's
consolidated financial statements in accordance with generally accepted auditing
standards and expressing an opinion on the conformity of the financial
statements to generally accepted accounting principles. The internal auditors
are responsible to the Audit Committee and the Board for testing the integrity
of the financial accounting and reporting control systems and such other matters
as the Audit Committee and Board determine.

    In this context, the Audit Committee has met and held discussions with
management, the internal auditors and the independent auditors concerning the
consolidated financial statements for the fiscal year ended September 30, 2002.
Management represented to the Committee that Tyco's consolidated financial
statements were prepared in accordance with generally accepted accounting
principles, and the Committee has reviewed and discussed the consolidated
financial statements with management, the internal auditors and the independent
auditors. The Committee discussed with the independent auditors the matters
required to be discussed by Statement on Auditing Standards No. 61
(Communication with Audit Committees).

    In addition, the Committee has discussed with the independent auditors the
auditors' independence from Tyco and its management, including the matters in
the written disclosures required by the Independence Standards Board Standard
No. 1 (Independence Discussions with Audit Committees). The Committee also has
considered whether the independent auditors' provision of information technology
and other non-audit services to Tyco is compatible with the auditors'
independence.

    Based upon the Committee's review and discussions referred to above, the
Committee recommended that the Board include Tyco's audited consolidated
financial statements in Tyco's Annual Report on Form 10-K for the fiscal year
ended September 30, 2002 filed with the Securities and Exchange Commission.

Submitted by the Audit Committee,

Richard S. Bodman, Chairman
Wendy E. Lane
Dated January 15, 2003

                    PROPOSALS FOR THE ANNUAL GENERAL MEETING

    Tyco intends to present proposals numbered 1 through 3 for shareholder
consideration and voting at the Annual General Meeting. In addition,
shareholders of Tyco have informed us that they intend to present proposals
numbered 4 through 9 at the Annual General Meeting, in which case those
proposals will also be voted upon if properly presented at the Annual General
Meeting. Other than matters incident to the conduct of the Annual General
Meeting, including approval of the minutes of the 2002 Annual General Meeting,
Tyco does not know of any business or proposals to be considered at the Annual
General Meeting other than those set forth in this Proxy Statement. If any other
business is proposed and properly presented at the Annual General Meeting, the
proxies received from our shareholders give the proxy holders the authority to
vote on the matter according to their best judgment.

PROPOSAL NUMBER ONE--ELECTION OF DIRECTORS

    The size of Tyco's Board is currently eleven directors. All of our directors
who were Board members prior to the appointment of Tyco's new Chairman and Chief
Executive Officer in July 2002 have determined not to stand for re-election. In
August 2002, John A. Krol joined the Board and became the new Chairman of the
Board's Corporate Governance and Nominating Committee. On September 12, 2002,
the Board nominated Jerome B. York, Mackey J. McDonald, George W. Buckley, Bruce
S. Gordon and Sandra S. Wijnberg to fill vacancies created as directors resign.
On November 7, 2002, the Board nominated Dennis C. Blair, and on December 16,
2002, the Board nominated Brendan R. O'Neill, to fill additional vacancies
created as directors resign. Messrs. York and McDonald joined the Board to fill
vacancies created by the resignation of directors in November 2002, Mr. Buckley
joined the Board to fill a vacancy created by the resignation of a director in
December 2002 and Mr. Gordon joined the Board to fill a vacancy created by the
resignation of a director in January 2003. Upon the recommendation of the
Corporate Governance and Nominating Committee, the Board has nominated for
election at the 2003 Annual General Meeting a slate of nine nominees:
Messrs. Breen, Krol, York, McDonald, Buckley and Gordon, all of whom are
currently serving on the Board, as well as Messrs. Blair and O'Neill and
Ms. Wijnberg. Biographical information regarding each of the nine nominees is
set forth beginning on page 7 above, under the caption "Directors and Director
Nominees." To the extent that any additional vacancies occur on the Board prior
to the date of the Annual General Meeting, they will be filled by one of the
nominees who does not currently serve on the Board.

    The election of directors will take place at the Annual General Meeting.
Election of each director requires the affirmative vote of a majority of the
votes cast by the holders of common shares represented at the Annual General
Meeting in person or by proxy. Shareholders are entitled to one vote per share
for each of the nine directors to be elected. If the nine nominees are elected,
the size of Tyco's Board will be set at nine directors. Tyco is not aware of any
reason why any of the nominees will not be able to serve if elected. Each of the
directors elected will serve until the 2004 Annual General Meeting and until
their successors, if any, are elected and qualified.

    THE BOARD RECOMMENDS THAT SHAREHOLDERS VOTE FOR THE ELECTION OF THE NINE
(9) NOMINEES.

PROPOSAL NUMBER TWO--RE-APPOINTMENT OF INDEPENDENT AUDITORS AND
  AUTHORIZATION OF THE AUDIT COMMITTEE TO SET THEIR REMUNERATION

    In accordance with Section 89 of the Companies Act 1981 of Bermuda, Tyco's
shareholders have the authority to appoint Tyco's independent auditors and to
authorize the Audit Committee of the Board to set the auditors' remuneration. At
the meeting, shareholders will be asked to re-appoint PricewaterhouseCoopers LLP
as Tyco's independent auditors and to authorize the Audit Committee of the Board
to set their remuneration. Audit services performed by PricewaterhouseCoopers
LLP for Tyco in fiscal 2002 included the examination of the consolidated
financial statements of Tyco and its subsidiaries. Appointment of the
independent auditors requires the affirmative vote of a majority of the votes
cast by the holders of common shares represented at the Annual General Meeting
in person or by proxy.

                                       12
<Page>
    In addition to retaining PricewaterhouseCoopers LLP to audit the
consolidated financial statements of Tyco and its subsidiaries for fiscal 2002,
Tyco retained PricewaterhouseCoopers LLP, as well as other accounting and
consulting firms, to provide various non-audit services in fiscal 2002. The
aggregate fees billed for professional services by PricewaterhouseCoopers in
fiscal 2002 for the various services they performed were:

    - AUDIT FEES: $16.3 million for services rendered for the annual audit of
      Tyco's consolidated financial statements for fiscal 2002 and the quarterly
      reviews of the financial statements included in Tyco's Quarterly Reports
      on Form 10-Q (all references to "$" in this Proxy Statement are to United
      States dollars.);

    - FINANCIAL INFORMATION SYSTEMS DESIGN AND IMPLEMENTATION FEES:
      $2.7 million for services rendered in connection with the design or
      implementation of hardware or software systems that aggregate source data
      or generate information that is significant to the financial statements
      taken as a whole; and

    - ALL OTHER FEES: A total of $31.9 million for all other services, including
      $11.6 million for tax-related services; $11.3 million for non-financial
      statement audit services such as due diligence procedures associated with
      mergers and acquisitions, accounting consultation, SEC reviews and
      registration statement-related work, benefit plan audits, etc.; and
      $9.0 million for statutory audit work in non-U.S. countries unrelated to
      the financial statement audit.

    The Securities and Exchange Commission ("SEC") has proposed rules to
redefine the types of services that are included as audit services and to create
new reporting categories for "audit-related services" and "tax services". If
these proposed rules were in place currently, certain of the fees categorized as
"All Other Fees," such as fees for statutory audit work, benefit plan audits,
due diligence procedures associated with mergers and acquisitions, and
tax-related services, would be categorized as Audit Fees, Audit-Related Fees or
Tax Fees.

    Representatives of PricewaterhouseCoopers LLP are expected to be at the
Annual General Meeting to present the independent auditors' report. They will
also be given the opportunity to make a statement if they desire to do so, and
they will be available to respond to appropriate questions.

    THE BOARD RECOMMENDS THAT SHAREHOLDERS VOTE FOR THE RE-APPOINTMENT OF
PRICEWATERHOUSECOOPERS LLP AND THE AUTHORIZATION OF THE AUDIT COMMITTEE TO SET
THEIR REMUNERATION.

PROPOSAL NUMBER THREE--INCREASE IN THE NUMBER OF AUTHORIZED COMMON SHARES AND
  AMENDMENT TO TYCO'S BYE-LAWS TO REFLECT SUCH INCREASE

    Shareholders are being asked to consider and approve an increase in the
number of authorized common shares from 2,500,000,000 to 4,000,000,000 and an
amendment to Tyco's Bye-Laws to reflect such increase. This proposal was
unanimously approved by Tyco's Board and recommended for approval by the
shareholders.

    Our Board believes that it is in Tyco's best interest and the best interest
of Tyco's shareholders to increase the company's authorized common share capital
from 2,500,000,000 to 4,000,000,000 common shares. On January 9, 2003, there
were 1,995,890,462 common shares of Tyco outstanding. In addition, as of such
date, 356,071,235 common shares were reserved for issuance upon exercise of
convertible securities or under equity compensation plans. Accordingly, as of
January 9, 2003, only 148,038,303 common shares are otherwise available for
issuance. If this proposal is approved and effected, Tyco will have available
1,648,038,303 authorized but unissued and unreserved common shares.

    Our Board believes that it is prudent to have additional common shares
available for general corporate purposes, including future public or private
offerings, acquisitions of other businesses or properties, stock splits or stock
dividends. Tyco has no current plans for the issuance of any common shares,
except under existing compensation plans and outstanding convertible securities.
As Tyco has a

                                       13
<Page>
sufficient number of existing authorized and unissued common shares, approval of
this proposal is not necessary to satisfy these requirements.

    Unless otherwise required by applicable law or regulation, all authorized
but unissued and unreserved common shares will be issuable, without any further
authorization by the shareholders, on the terms and for such consideration as
our Board may determine. Tyco does not expect that shareholder approval will be
sought, unless required by applicable law, regulation or exchange listing
standard as a condition to the issuance of common shares in any particular
transaction.

    The sale of a substantial number of common shares to persons who have an
understanding with us concerning the voting of such common shares, or the
distribution or dividend of common shares (or the right to receive common
shares) to our shareholders, may have the effect of discouraging unsolicited
attempts to acquire control of Tyco. In addition, any issuance of additional
common shares could have the effect of diluting the earnings per share and book
value per share of existing common shares, and such additional common shares
could be used to dilute the share ownership of a person seeking to obtain
control of Tyco. Senior management and the Board have no knowledge of any effort
by any person to obtain control of Tyco, and the Board has no present intention
of issuing any common shares with the understanding that the purchasers would
vote their common shares in any particular way or of distributing common shares
or rights to Tyco's shareholders. Common shareholders do not have preemptive
rights to subscribe to additional securities that Tyco may issue, which means
that current shareholders do not have a prior right to purchase any new issue of
shares in order to maintain their proportionate ownership.

    A copy of the form of amendment to the Bye-Laws is attached to this Proxy
Statement as Exhibit B.

    This proposal has been unanimously approved by Tyco's Board and recommended
for approval by the shareholders. The affirmative vote of a majority of the
common shares represented and voting at the Annual General Meeting is required
for approval of this proposal.

    THE BOARD RECOMMENDS THAT YOU VOTE FOR THE RESOLUTION TO INCREASE THE NUMBER
OF AUTHORIZED COMMON SHARES AND TO AMEND TYCO'S BYE-LAWS TO REFLECT SUCH
INCREASE.

PROPOSAL NUMBER FOUR--SHAREHOLDER PROPOSAL REGARDING THE MANUFACTURE
  OF PVC- OR PHTHALATE-CONTAINING MEDICAL SUPPLIES

    Christian Brothers Investment Services, Inc., 90 Park Avenue, 29th Floor,
New York, NY 10016-1301, a shareholder that as of September 23, 2002 owned
68,518 common shares, has notified Tyco of its intention to propose the
resolution set forth below at the Annual General Meeting. Catholic Healthcare
West, 1700 Montgomery Street, Suite 300, San Francisco, CA 94111-1024, which, as
of September 24, 2002 owned 400 common shares and The Sisters of Mercy,
Burlingame, 2300 Adeline Drive, Burlingame, CA 94010-5599, which, as of
September 26, 2002, owned 200 common shares, have indicated their intention to
co-sponsor this proposal.

    WHEREAS:

    Polyvinyl chloride (PVC) plastic, the primary component in 25% of all
    medical products, including IV, blood, enteral feeding bags and others,
    creates dioxin in production and disposal.

    Dioxin, a known human carcinogen, has been linked to endocrine (hormone
    system) disruption, reproductive abnormalities, altered glucose tolerance,
    testicular atrophy, neurological problems, infertility and other effects in
    animals and humans.

    The Environmental Protection Agency has determined that the U.S. population
    already has bodily dioxin levels at or near levels which can cause adverse
    effects in laboratory animals.

    Large quantities of chemicals called "phthalates" are used to manufacture
    flexible PVC medical products. Flexible PVC products may contain significant
    amounts of di-ethylhexyl-phthalate (DEHP), a plasticizer that is a probable
    reproductive toxicant and toxicant of the liver and kidney.

                                       14
<Page>
    DEHP has been found to leach out of medical devices and into fluids they are
    carrying, putting vulnerable populations (e.g., premature infants, dialysis
    patients and pregnant women) at risk of adverse health effects related to
    DEHP exposure.

    A National Toxicology Program's "Expert Panel" expressed "serious concern"
    about DEHP exposures from PVC medical devices used in the treatment of
    critically ill infants.

    The Food and Drug Administration (FDA) issued a public health notification
    identifying a number of medical procedures that posed the highest patient
    risk from DEHP exposure, including enteral nutrition, infants receiving
    parenteral nutrition and exchange transfusions.

    In its recent draft guidance document, FDA recommends that medical device
    manufacturers help minimize patient exposure to DEHP by clearly indicating
    "through user labeling" that devices contain DEHP, and by "replacing PVC
    containing DEHP" with alternative materials.

    An expert advisory panel's report to Health Canada recommended that PVC
    devices containing DEHP should not be used in a number of circumstances
    including: all newborns and pre-pubertal males; high exposure procedures
    such as ECMO; some adults such as heart transplant patients; pregnant and
    lactating women.

    Other manufacturers have announced the development of cost-effective,
    high-quality alternatives to PVC, responding to the growing market for
    non-PVC medical supplies, although alternatives are not always available.

    Eliminating potential risks and liabilities associated with the sale of PVC
    medical devices may be consistent with efforts to restore investor
    confidence in the company.

    THEREFORE, BE IT RESOLVED that the shareholders request the Board of
    Directors of Tyco International to adopt a policy of phasing out the
    manufacture of PVC-containing or phthalate-containing medical supplies by
    its Kendall Healthcare subsidiary where safe alternatives are available.

    SUPPORTING STATEMENT

    Establishing as a priority the manufacture of blood bags and tubing without
    phthalate plasticizers would provide safer patient care in applications
    which currently expose patients to the greatest health risks. To implement
    this policy, the company might choose to: maintain an inventory of products
    which contain PVC or DEHP; investigate and track the availability of
    alternatives; establish policies for environmentally preferable
    manufacturing; request suppliers and purchasers to aid in the development of
    alternatives. By adopting these mechanisms, Tyco will demonstrate that there
    is a market for such devices, encourage development and marketing of
    additional alternative products, and demonstrate commitment to safe
    products.

RECOMMENDATION OF THE BOARD OF DIRECTORS ON PROPOSAL NUMBER FOUR

    The Board believes that adopting a policy requiring Tyco to phase-out the
production of polyvinyl chloride ("PVC")-containing or phthalate-containing
medical supplies would not be in the best interest of patients, health care
providers, Tyco or its shareholders, and recommends that you vote "AGAINST" the
proposal.

    As a supplier of health care products and services, Tyco is committed to
providing life-sustaining medical products and services that can safely and
effectively meet the needs of its health care customers and the patients who
rely on its products. The Board believes that Tyco should have the ability to
choose the most appropriate component materials for its products that would
enable it to achieve this goal. Tyco stays abreast of new developments and
relies on scientific research data to determine the safety of materials used in
its products. Tyco regularly explores alternative materials and will use them
when they are shown to be superior overall to materials currently used.

    PVC and di-ethylhexyl-phthalate ("DEHP") have a history of over 40 years of
safe and effective use in a variety of medical products, such as tubing and
solution bags, and have undergone strict regulatory

                                       15
<Page>
review by the U.S. Food and Drug Administration and many other governmental and
independent health agencies throughout the world. One recent study concerning
the use of PVC in medical products was the American Council on Science and
Health study published in 1999. This study was chaired by former U.S. Surgeon
General C. Everett Koop, and commissioned over 200 physicians and scientists. It
did not find a causal link between DEHP and human health risk. In addition,
numerous scientific studies by organizations such as the World Health
Organization demonstrate that PVC-and DEHP-containing medical products are safe.
Tyco is guided by and follows applicable FDA regulations concerning the medical
products that it manufactures. Tyco believes that the FDA is the proper agency
to determine the safety of such products, and Tyco is committed to the integrity
of that process.

    Tyco uses PVC for certain of its medical products because of its clarity,
flexibility, kink-resistance and processability, as well as for its
cost-effectiveness. The disposable medical device industry has looked to PVC
since the 1950s to provide cost-effective engineered solutions for providing and
improving health care delivery. Environmental concerns relating to the
manufacture and disposal of PVC that have arisen in recent years are being
addressed with modern pollution control technologies. Tyco believes that this
combination of proven utility, cost-effectiveness, and environmental progress
are each important considerations in evaluating manufacturing alternatives for
the medical supplies it produces.

    Tyco is aware that, in certain cases, alternatives to materials containing
PVC and DEHP may be appropriate for particular applications and therefore merit
investigation. For this reason, Tyco regularly evaluates a variety of materials
and allocates funding for the research and development of non-PVC alternative
polymers and commercial development of non-PVC medical products. Tyco believes
that substitute technology should be evaluated on a case-by-case basis, and, in
circumstances where an alternative material is proven to be superior overall to
PVC and regulatory clearance is obtained, Tyco will offer or convert to the
alternative. In the meantime, however, the Board believes that management must
have the flexibility to use the optimal materials available for any particular
application, consistent with evaluating their health and safety aspects. Tyco
should not be precluded from considering materials that have been found to be
safe, reliable and effective.

    For all of these reasons, the Board recommends that you vote against
adopting a policy requiring Tyco to phase out the production of PVC-containing
and phthalate-containing medical supplies.

    THE BOARD RECOMMENDS A VOTE AGAINST THIS SHAREHOLDER PROPOSAL.

PROPOSAL NUMBER FIVE--SHAREHOLDER PROPOSAL REGARDING SHAREHOLDER
  APPROVAL OF FUTURE SEVERANCE AGREEMENTS

    American Federation of Labor and Congress of Industrial Organizations
(AFL-CIO) Reserve Fund, 815 Sixteenth Street, N.W., Washington, D.C. 20006, a
shareholder that as of September 26, 2002 owned 1,200 common shares, has
notified the Tyco of its intention to propose the following resolution at the
Annual General Meeting:

    RESOLVED: That the shareholders of Tyco International Ltd. ("Tyco" or the
    "Company") urge the Board of Directors to seek shareholder approval for
    future severance agreements with senior executives that provide benefits in
    an amount exceeding 2.99 times the sum of the executive's base salary plus
    bonus. "Future severance agreements" include employment agreements
    containing severance provisions; retirement agreements; and agreements
    renewing, modifying or extending existing such agreements. "Benefits"
    include lump-sum cash payments and the estimated present value of periodic
    retirement payments, fringe benefits, perquisites, and consulting fees to be
    paid to the executive.

    SUPPORTING STATEMENT

    On January 22, 2001, Tyco entered into an employment agreement with Chairman
    and Chief Executive Officer Dennis Kozlowski. Under this employment
    agreement, Kozlowski was promised the

                                       16
<Page>
    following severance compensation should he be dismissed without cause or
    following a change in control:

       - A lump sum of three times his annual salary and bonus;

       - Immediate vesting of all stock options and restricted stock;

       - A lifetime consulting agreement with the Company;

       - Welfare and fringe benefits including access to Company facilities;

       - Credit for three additional years of pension service; and

       - A tax gross up for any resulting excise taxes.

    In our opinion, this severance agreement commonly known as a "golden
    parachute" is excessive given the high levels of compensation previously
    awarded Kozlowski. According to the Wall Street Journal, this severance
    agreement would have paid Kozlowski about $135 million, plus a consulting
    retainer of $3.4 million annually for the rest of his life. The Wall Street
    Journal calculates that in the past three fiscal years, he has been paid
    about $97 million by Tyco in cash, restricted stock and other compensation,
    and has reaped $240 million by exercising stock options.

    We believe that requiring shareholder approval of such agreements may have
    the beneficial effect of insulating the Board of Directors from manipulation
    in the event a senior executive's employment must be terminated by the
    Company. Because it is not always practical to obtain prior shareholder
    approval, the Company would have the option, if it implemented this
    proposal, of seeking approval after the material terms of the agreement were
    agreed upon.

    We are concerned that severance agreements weaken the negotiating position
    of the Board of Directors in the event of the need to replace senior
    executives. Fortunately for shareholders, Kozlowski voluntarily resigned for
    "personal reasons" thereby releasing Tyco from the terms of his severance
    agreement. Under the terms of this agreement, Tyco could dismiss Kozlowski
    "for cause" only if he was convicted of a "felony that is materially and
    demonstrably injurious to the Company" and following a vote of
    three-quarters of the entire Board of Directors.

    The California Public Employees Retirement System, the Council of
    Institutional Investors, and Institutional Shareholder Services generally
    favor requiring shareholder approval of these types of severance agreements.
    For these reasons we urge shareholders to vote FOR this proposal.

RECOMMENDATION OF THE BOARD OF DIRECTORS ON PROPOSAL NUMBER FIVE

    For the reasons described below, the Board believes that the shareholder
proposal is not in the best interests of Tyco and its shareholders and therefore
recommends a vote "AGAINST" the proposal.

    The Board believes that compensation arrangements with executives, including
severance agreements, should continue to be the responsibility of the Board's
Compensation Committee and the Board as a whole. The Board believes that it is
important to retain the flexibility to enter into executive employment
arrangements, which typically include severance provisions, so that Tyco can
compete effectively in attracting and retaining qualified executives. However,
placing arbitrary ceilings or restrictions on what Tyco may offer as severance
payments or requiring shareholder approval of the terms of each severance
agreement, as would be required under the Proposal, would make it difficult to
attract new executives and to provide a new executive with a competitive
employment package. For example, if Tyco were to delay entering into employment
and severance agreements pending shareholder approval or ratification, highly
sought-after executives could choose to pursue other career opportunities and
competitors could seek to hire prospects away from Tyco. The Board also believes
that, as a practical matter, it is often necessary to maintain confidentiality
as to employment agreement negotiations in order to attract highly-skilled
executives, because potential candidates will not want their current employers
to learn of their job negotiations until they have finalized the terms of a new
employment agreement and Tyco would not want competitors to learn who it is
seeking to hire or the employment terms it is proposing to offer.

                                       17
<Page>
    Tyco is transitioning to a new Compensation Committee. The Compensation
Committee, on an ongoing basis, will devote considerable time and effort to
executive compensation issues, including the balance to be struck among various
objectives of Tyco's executive compensation programs. Given the challenges
currently facing Tyco, the Board believes that any requirement to cap the value
of severance provisions or to obtain shareholder approval of severance
provisions would unduly inhibit Tyco's ability to recruit and retain talented
executives by imposing a rigid limitation or a time-consuming procedural
requirement. The Board believes that it is ultimately in the shareholders' best
interests that the responsibility for this ongoing process continues to be
vested in the Compensation Committee and your Board.

    THE BOARD RECOMMENDS A VOTE AGAINST THIS SHAREHOLDER PROPOSAL.

PROPOSAL NUMBER SIX--SHAREHOLDER PROPOSAL REGARDING USE OF STOCK PRICE INDEXED
  EXECUTIVE STOCK OPTIONS

    United Brotherhood of Carpenters Pension Fund, 101 Constitution Avenue,
N.W., Washington, D.C. 20001, a shareholder that as of September 30, 2002 owned
9,028 common shares, has notified Tyco of its intention to propose the following
resolution at the Annual General Meeting:

    RESOLVED, that the shareholders of Tyco International Ltd. (the "Company")
    request that the Board of Directors adopt an executive compensation policy
    that all future stock option grants to senior executives shall be
    performance-based. For the purposes of this resolution, a stock option is
    performance-based if the option exercise price is indexed or linked to an
    industry peer group stock performance index so that the options have value
    only to the extent that the Company's stock price performance exceeds the
    peer group performance level.

    STATEMENT OF SUPPORT

    As long-term shareholders of the Company, we support executive compensation
    policies and practices that provide challenging performance objectives and
    serve to motivate executives to achieve long-term corporate value
    maximization goals. We believe that stock option grants can and do often
    provide levels of compensation well beyond those merited. Further, we
    believe that stock option grants without specific performance-based targets
    often reward executives for stock price increases due solely to a general
    stock market rise, rather than to extraordinary company performance.

    The resolution advocates performance-based stock options. It defines
    performance-based stock options as indexed options whose exercise price
    moves with an appropriate peer group index composed of a company's primary
    competitors. It should be noted that there are other forms of indexed
    options that use other types of market indices. The resolution requests that
    the Company's Board ensure that future Company stock option plans link the
    options exercise price to an industry performance index associated with a
    peer group of companies selected by the Board, such as those companies used
    in the Company's proxy statement to compare 5 year stock price performance.

    Implementing an indexed stock option plan would mean that our Company's
    participating executives would receive payouts only if the Company's stock
    price performance was better than that of the peer group average. By tying
    the exercise price to a market index, indexed options reward participating
    executives for outperforming the competition. Indexed options would have
    value when our Company's stock price rises in excess of its peer group
    average or declines less than its peer group average stock price decline. By
    downwardly adjusting the exercise price of the option during a downturn in
    the industry, indexed options remove pressure to reprice stock options. In
    short, superior performance would be rewarded.

    At present, stock options granted by the Company are not indexed to peer
    group performance standards. As long-term owners, we feel strongly that our
    Company would benefit from the

                                       18
<Page>
    implementation of a stock option program that rewarded superior long-term
    corporate performance. We urge your support for this important governance
    reform.

RECOMMENDATION OF THE BOARD OF DIRECTORS ON PROPOSAL NUMBER SIX

    Tyco's Board and Compensation Committee strongly support the concept of
performance-based compensation arrangements as a critical component of executive
compensation. However, for the reasons described below, the Board believes that
adopting a policy of linking all future executive stock options to an industry
peer group stock performance index would unduly restrict the Compensation
Committee's choice among performance-based compensation arrangements, and
therefore would not be in the best interests of Tyco's shareholders. The Board
therefore recommends that you vote "AGAINST" the proposal.

    The Compensation Committee of the Board reviews, approves and oversees all
of the policies under which compensation is paid to Tyco's executives. The Board
believes that it is important to preserve the flexibility of its compensation
program so that the Compensation Committee can choose incentives that best
balance the variety of goals that Tyco seeks to pursue through its compensation
arrangements. Tyco is transitioning to a newly constituted Compensation
Committee that over the coming year will consider a variety of compensation
arrangements for its executives. In choosing what type of performance-based
compensation scheme to use for its executives, the Committee must consider a
variety of factors, such as what goals the Board has established for management,
tax consequences of various arrangements and competitive practice.

    The proposal would limit the Compensation Committee's flexibility by
requiring that stock options be tied to a specific performance measure--a peer
group stock performance index--in a specific way (by tying the exercise price,
rather than amounts granted or the vesting schedules, to a performance measure).
As the Board evaluates Tyco's operations and business goals, the Board believes
that the Compensation Committee should have the flexibility to measure
performance by criteria other than relative stock price performance and to tie
options to these other criteria or to grant traditional fixed-price options and
tie other forms of annual or long-term compensation to performance criteria that
are varied from time to time, as Tyco's goals and challenges change.

    In addition, the selection of performance criteria can affect whether
performance-based compensation qualifies for deductibility under
shareholder-approved performance criteria for purposes of Section 162(m) of the
Internal Revenue Code. Under Tyco's existing shareholder-approved compensation
plans, the type of options advocated in the proposal may not be deductible to
Tyco.

    Finally, the Board believes that the Compensation Committee should have the
ability to establish compensation policies in light of the competitive
environment in which Tyco must compete for executive talent. Tyco's current
stock option program is the type used by the vast majority of corporations. The
Board believes that limiting the Compensation Committee's ability to design a
compensation system in line with that of other companies could place Tyco at a
competitive disadvantage in recruiting executives.

    For all of these reasons, the Board recommends that you vote against
adopting a policy of limiting future stock option grants to price-indexed
options.

    THE BOARD RECOMMENDS A VOTE AGAINST THIS SHAREHOLDER PROPOSAL.

PROPOSAL NUMBER SEVEN--SHAREHOLDER PROPOSAL REGARDING CHANGING TYCO'S
  JURISDICTION OF INCORPORATION

    American Federation of State, County and Municipal Employees (AFSCME)
Employees Pension Plan, 1625 L Street, N.W., Washington, D.C. 20036, a
shareholder that as of September 26, 2002 owned

                                       19
<Page>
424,505 common shares, has notified Tyco of its intention to propose the
following resolution at the Annual General Meeting:

    RESOLVED, that the shareholders of Tyco International Ltd. ("Tyco") urge
    Tyco's Board of Directors to take the measures necessary to change Tyco's
    jurisdiction of incorporation from Bermuda to Delaware.

    SUPPORTING STATEMENT

    Tyco and its shareholders would benefit if Tyco changed its jurisdiction of
    incorporation from Bermuda to Delaware. First, Delaware's corporate laws are
    updated to meet changing business needs and are more responsive than Bermuda
    law to the needs of shareholders. Delaware is the state of incorporation for
    60% of Fortune 500 companies, according to the Delaware Division of
    Corporations. We believe that so many companies choose to incorporate in
    Delaware because it has an advanced and flexible corporate law, expert
    specialized courts dealing with corporate-law issues, a responsive state
    legislature and a highly-developed body of case law that allows corporations
    and shareholders to understand the consequences of their actions and plan
    accordingly. We believe the stability, transparency and predictability of
    Delaware's corporate-law framework are superior to Bermuda's and provide
    advantages to shareholders.

    Second, incorporation in Bermuda makes it more difficult for shareholders to
    hold companies, their officers and directors legally accountable in the
    event of wrongdoing. Recent events, we think, demonstrate how crucial it is
    that, in the event of legal violations by officers or directors,
    shareholders have the ability to pursue legal remedies. Unlike both U.S.
    federal and Delaware law, class actions are generally not available under
    Bermuda law. Under Bermuda law, shareholders have extremely limited ability
    to sue officers and directors derivatively, on behalf of the corporation. By
    contrast, under Delaware law, shareholders may sue derivatively for, among
    other things, breach of fiduciary duty, corporate waste and actions taken in
    violation of applicable law.

    Third, Delaware law affords shareholders rights not provided under Bermuda
    law. Unlike Delaware law, Bermuda law does not require shareholder approval
    for a corporation to dispose of all or substantially all of its assets.
    Bermuda law does not permit action by written consent of fewer than all
    shareholders, while Delaware law does.

    Fourth, incorporation in Bermuda may affect the enforceability of judgments
    obtained in a U.S. court. A judgment for money damages based on civil
    liability rendered by a U.S. court is not automatically enforceable in
    Bermuda because the U.S. and Bermuda do not have a treaty providing for
    reciprocal enforcement of judgments in civil matters. A Bermuda court may
    not recognize a judgment of a U.S. court if it is deemed contrary to Bermuda
    public policy, and Bermuda public policy may differ significantly from U.S.
    public policy.

RECOMMENDATION OF THE BOARD OF DIRECTORS ON PROPOSAL NUMBER SEVEN

    The Board believes that it is appropriate to evaluate periodically whether
to reincorporate Tyco from Bermuda and into a different jurisdiction, such as
Delaware or another state in the U.S. To this end, the Board intends to evaluate
the potential benefits, costs and disadvantages of such a move. However, because
the Board presently is newly constituted and has not had the opportunity to
undertake this review, the Board is not in a position to endorse this proposal
to reincorporate into Delaware. Accordingly, the Board recommends that
shareholders vote "AGAINST" this proposal.

    Tyco became a Bermuda company in July 1997 when its shareholders approved
its business combination with ADT Limited. ADT Limited was incorporated in
Bermuda in 1984. Although it is domiciled in Bermuda, Tyco is fully subject to
the U.S. securities laws and the rules and regulations of the SEC. Tyco is also
subject to the New York Stock Exchange requirements for listed companies,
including its

                                       20
<Page>
corporate governance provisions. Tyco's extensive facilities and operations in
the U.S. mean that Tyco is not removed from the U.S. legal system: it is
possible for Tyco to be sued in the U.S. and for judgments to be enforced in the
U.S. Likewise, contrary to what is suggested in the proposal, Tyco's
jurisdiction of incorporation has not prevented class action lawsuits from being
asserted against Tyco.

    A part of any review on whether to reincorporate into a different
jurisdiction would include evaluating the potential benefits, costs and
disadvantages of remaining a Bermuda company or reincorporating into a different
jurisdiction, the effect that jurisdiction of incorporation has on overall cost
and financial structure, as well as the costs involved in reincorporating into
another jurisdiction. Additional factors for review include any non-financial
implications of its state of incorporation, including the similarities and
differences, if any, of the rights and protections afforded shareholders under
Bermuda law and the laws of U.S.-based jurisdictions, including Delaware.

    For the reasons discussed above, the Board recommends that you vote against
the resolution requesting Tyco to change Tyco's jurisdiction of incorporation.

    THE BOARD RECOMMENDS A VOTE AGAINST THIS SHAREHOLDER PROPOSAL.

PROPOSAL NUMBER EIGHT--SHAREHOLDER PROPOSAL REGARDING NON-EXECUTIVE INDEPENDENT
  CHAIRMAN OF THE BOARD

    Amalgamated Bank LongView Collective Investment Fund and Amalgamated Bank
LongView 1500 Total Market Index Fund, 11-15 Union Square, New York, NY 10003,
shareholders that as of September 26, 2002 own 603,775 and 58,455 common shares,
respectively, have notified Tyco of their intention to propose the following
resolution at the Annual General Meeting:

    RESOLVED: The shareholders of Tyco International, Ltd. ("Tyco" or the
    "Company") urge the board of directors to amend the bylaws to require that,
    effective upon the expiration of the existing employment agreement, an
    independent director who has not served as chief executive officer ("CEO")
    of the Company shall serve as chairman of the board of directors.

    SUPPORTING STATEMENT

    The primary purpose of the board of directors is to protect shareholders'
    interests by providing independent oversight of management, including the
    CEO. Such oversight is important, particularly in light of the recent
    controversy surrounding Tyco's former chairman and CEO, L. Dennis Kozlowski.
    We believe that separating the roles of chairman and CEO will promote
    greater management accountability to Tyco shareholders.

    Corporate governance experts have questioned how one person serving as both
    chairman and CEO can effectively monitor and evaluate his or her own
    performance. The NACD Blue Ribbon Commission on Director Professionalism has
    recommended that an independent director should be charged with "organizing
    the board's evaluation of the CEO and providing continuous ongoing feedback;
    chairing executive sessions of the board; setting the agenda with the CEO,
    and leading the board in anticipating and responding to crises."

    Many institutional investors believe that a strong, objective board leader
    can best provide the necessary oversight of management. Thus, CalPERS'
    CORPORATE GOVERNANCE CORE PRINCIPLES AND GUIDELINES states that "the
    independence of a majority of the board is not enough" and that "the
    leadership of the board must embrace independence, and it must ultimately
    change the way in which directors interact with management."

    We believe that formally separating the two positions will help enhance
    investor confidence in Tyco, which we view as vital in light of the pending
    criminal indictments of Mr. Kozlowski and Tyco's former

                                       21
<Page>
    chief financial and legal officers, as well as a pending SEC civil fraud
    suit. The criminal cases charge Mr. Kozlowski and Mark H. Swartz, the former
    CFO, with enterprise corruption, fraud, conspiracy, grand larceny, and other
    crimes, and Mark A. Belnick, the former chief corporate counsel, with
    falsification of business records.

    Messrs. Kozlowski and Swartz are accused of granting themselves hundreds of
    millions of dollars in secret low interest and interest-free loans that they
    used for personal expenses and of causing Tyco to forgive tens of millions
    of dollars, again without disclosure to investors as required by the federal
    securities laws.

    Tyco has filed its own suit, which is pending, and stated in an SEC filing
    that the three former officials engaged in a "pattern of improper and
    illegal conduct by which they enriched themselves at the expense of the
    Company with no colorable benefit to the Company and concealed their conduct
    from the Board and its relevant committees."

    We believe that these events call into question the effectiveness of a
    governance structure that combined the roles of CEO and chairman in one
    person and that a bylaw creating an independent chairman will strengthen the
    board's integrity and effectiveness.

    We urge a vote FOR this resolution.

RECOMMENDATION OF THE BOARD OF DIRECTORS ON PROPOSAL NUMBER EIGHT

    The Board strongly endorses the view that one of its primary functions is to
protect shareholders' interests by providing independent oversight of
management, including the CEO. For this reason, the Board concurs with many of
the statements expressed by the proponents in their Supporting Statement above.
However, the Board does not believe that mandating a particular structure, such
as a separate chairman and CEO, is necessary to achieve effective oversight.
Accordingly, for the reasons discussed below, the Board believes that the
shareholder proposal is not in the best interests of Tyco and its shareholders
and therefore recommends a vote "AGAINST" the proposal.

    The Board is committed to strong principles of corporate governance. In the
past several months, it has appointed a new senior management team, is
implementing new Board Governance Principles and is transitioning to a newly
constituted Board. The Board currently has a lead independent director and
expects to formalize this arrangement by providing that the independent
directors of the Board, acting in executive session, will elect a lead director,
who will be Chair of the Corporate Governance and Nominating Committee and
facilitate executive sessions of the Board.

    The Board believes that it should have the ability to select a style of
leadership, including whether to separate the position of CEO from Board chair,
that is appropriate depending on time and circumstances. Consistent with good
corporate governance principles, the Board expects that its Corporate Governance
and Nominating Committee will review the Board's organization annually and
recommend appropriate changes.

    The Board also does not believe that Tyco's past Board structure caused, or
even necessarily contributed to, the irresponsible and deplorable conduct of
Tyco's former executives. Many of America's best-run and most respected
companies are chaired by either current or former executives of those companies,
which would be precluded by the proposal. The Board believes that success is
promoted by active and independent directors and loyal and hard-working
executives who act consistently with a strong set of corporate governance
ethics, rather than a particular Board structure. For the reasons described
above, the Board believes that it is not appropriate to impose an absolute rule
against a current or former chief executive officer serving as Board chairman
and, therefore, opposes the resolution.

    THE BOARD RECOMMENDS A VOTE AGAINST THIS SHAREHOLDER PROPOSAL.

                                       22

PROPOSAL NUMBER NINE--SHAREHOLDER PROPOSAL REGARDING OBTAINING ONLY
  AUDIT SERVICES FROM TYCO'S INDEPENDENT AUDITORS

    International Brotherhood of Electrical Workers Pension Benefit Fund, 1125
Fifteenth Street, N.W., Washington, D.C. 20005, a shareholder that as of
September 27, 2002 owned 169,575 common shares, has notified Tyco of its
intention to propose the following resolution at the Annual General Meeting:

    RESOLVED: The shareholders of Tyco International (the "Company") urge the
    Board of Directors to adopt a policy that in the future the firm that is
    appointed to be the Company's independent accountants will only provide
    audit services to the Company and not provide any other services.

    SUPPORTING STATEMENT

    New disclosure requirements by the Securities and Exchange Commission
    required corporations, starting in 2001, to disclose how much they were
    paying their "independent" auditors for audit work and how much they were
    paying them for "other" work.

    The results were startling. Surveys by the Wall Street Journal and the
    Investor Responsibility Research Center each found that, on the average,
    corporations were paying their "independent" auditors three times more for
    "other" work than for their audit work. That raised the obvious concern as
    to how "independent" and objective the auditors really were. This concern
    was heightened by the subsequent accounting scandals at Enron and WorldCom.

    In response to these accounting concerns, President Bush signed into law the
    Sarbanes-Oxley Act, which places restriction on the types of non-audit
    services auditors can render in an effort to reduce the conflict of
    interests. While the new law is certainly a step in the right direction, it
    does contain a potential and serious loophole. The auditors can still render
    tax and certain other services as long as they are pre-approved by the audit
    committee.

    According to this Company's 2002 proxy statement, it paid its auditors
    $18.1 million for tax services and $13.2 million for audit services. Such a
    disparity in fees does not provide comfort to shareholders concerned about
    auditor conflicts of interest.

    In light of past criticisms of the lack of transparency of the Company's
    financial records and the scandals involving the Company's senior
    executives, it is respectfully submitted that this new Board of Directors
    could send a positive message to its investors and the public at large by
    adopting a policy that in the future its auditors would do no other work for
    the Company.

RECOMMENDATION OF THE BOARD OF DIRECTORS ON PROPOSAL NUMBER NINE

    The Board believes that this proposal would preclude Tyco's independent
auditors from performing services for Tyco even when the Board determines that
those services cannot be performed as effectively by other service providers and
that the services do not raise independence concerns. For the reasons discussed
below, the Board believes that the shareholder proposal is not in the best
interests of Tyco and its shareholders and therefore recommends a vote "AGAINST"
the proposal.

    In July 2002, Congress enacted and President Bush signed into law the
Sarbanes-Oxley Act of 2002. As part of the Sarbanes-Oxley Act, Congress
determined that independent auditors should not be permitted to provide certain
non-audit services to their audit clients. Yet, after carefully considering the
arguments for and against the provision of non-audit services by independent
auditors, Congress rejected an absolute ban on the provision of non-audit
services. Instead, Congress expressly determined that independent auditors may
provide non-audit services, other than those specifically prohibited, so long as
the services are approved in advance by the audit committee of a company's board
of directors. This determination is reflected in rules being implemented by the
SEC, which will permit independent auditors

                                       23
<Page>
to provide many non-audit services to their clients, provided those services are
approved in advance by the audit committee of a company's board of directors.

    Consistent with these provisions, Tyco's Audit Committee is developing
policies and procedures with respect to the pre-approval of any non-audit
services that it may request its independent auditors to provide. Further,
pursuant to existing standards, the Audit Committee and Tyco's independent
auditors periodically discuss the auditors' independence. Taking these
discussions into account, the Audit Committee specifically considers whether the
auditors' provision of non-audit services is compatible with maintaining the
auditors' independence. Moreover, Tyco annually discloses the amount of fees
paid to the independent auditors for non-audit services. The Board believes that
these procedures facilitate Audit Committee oversight and discussion on issues
that might impact the auditors' independence or objectivity.

    The law thus provides the Audit Committee flexibility to determine the most
suitable vendor for various non-audit services that Tyco requires. In making
such determinations, the Audit Committee may consider a wide variety of factors,
such as an accounting firm's cost, efficiency, expertise, familiarity with
Tyco's business, and protection of trade secrets and other confidential
information, as well as any potential effects on the independence or objectivity
of Tyco's auditors.

    In light of the ability of the Audit Committee to determine that, in some
circumstances, it can be appropriate to use Tyco's independent auditors to
provide non-audit services, as permitted by the Sarbanes-Oxley Act, and because
Tyco's Board and Audit Committee already monitor closely the independence of
Tyco's auditors, the Board believes it is not prudent for the shareholders to
adopt a comprehensive ban on the provision of all non-audit services. For all of
these reasons, the Board recommends that you vote against adopting a policy
requiring that Tyco's independent auditors provide only audit services to Tyco
and not provide any other services.

    THE BOARD RECOMMENDS A VOTE AGAINST THIS SHAREHOLDER PROPOSAL.

    October 31, 2002 (except for AXA Financial, Inc., where the amounts are as
    of February 12, 2002, and Messrs. Kozlowski and Swartz, where the amounts
    are as of the date they terminated employment with Tyco) based on
    information furnished by the persons named, public filings and Tyco's
    records. A person is deemed to be the beneficial owner of common shares if
    such person, either alone or with others, has the power to vote or to
    dispose of such common shares. Except as otherwise indicated below and
    subject to applicable community property laws, each owner has sole voting
    and sole investment authority with respect to the common shares listed. To
    the extent indicated in the notes below, common shares beneficially owned by
    a person include common shares of which the person has the right to acquire
    beneficial ownership within 60 days, including under stock options that were
    exercisable on October 31, 2002, or that become exercisable within 60 days
    after October 31, 2002. There were 1,995,866,326 Tyco common shares

                  DIRECTOR AND EXECUTIVE OFFICER COMPENSATION

DIRECTORS' COMPENSATION

FISCAL 2002 COMPENSATION

    The fiscal 2002 compensation package for non-employee directors (other than
Mr. Krol who joined the Board on August 6, 2002) consisted of $80,000 in cash
and 20,000 stock options that vest one year after issuance. Mr. Krol was
entitled to a pro-rata cash fee of $13,333.33 and a pro-rata grant of 3,333
stock options. Directors who are also employees receive no additional
remuneration for services as a director.

    For fiscal 2002, directors could make an irrevocable election to receive
some or all of their annual cash remuneration in one or more of the following
forms:

    - phantom Tyco common shares under a deferred compensation plan;

    - interest in a trust that is invested in Tyco common shares; or

    - Tyco stock options.

    Under the deferred compensation plan, a director's account is credited with
an amount equal to the dividends on the phantom common shares in the account as
if they were owned. Payments from the account are made in cash in either a lump
sum or up to ten annual installments at the prior election of the director.
Installments may begin at termination of service or, if the director is under
age 70, at a later date not to exceed age 70. In addition, a director may elect
to receive a lump sum payment at least five years after deferral, even if he
remains a director.

    Under the trust arrangement, a director is the owner of the common shares
credited to the director's account. The director may vote these common shares,
and the director may withdraw the common shares from the account or sell the
common shares at any time. Any common shares remaining in the account at the
time the director terminates his service on the Board will be distributed to him
at that time.

    Under the option-in-lieu-of-fee arrangement, a director is granted a number
of options with a value equal to the amount of cash remuneration foregone by the
director, calculated using the Black-Scholes option pricing model.

    The fiscal 2002 option grant was made on October 1, 2001, and the options
have an exercise price of $44.70 per share. Mr. Bodman, Mr. Foss, Ms. Lane,
Mr. Slusser and our former directors Lord Ashcroft, Joshua M. Berman, James S.
Pasman, Jr., Frank E. Walsh, Jr. and Joseph F. Welch elected to receive some or
all of their cash retainer for fiscal 2002 in stock options and were granted
options to purchase 4,660 Tyco common shares (2,330 for Mr. Slusser) at an
exercise price of $44.70 per share. Mr. Krol received his pro-rata option grant
of 3,333 options on August 6, 2002, and the options have a vesting date of
August 6, 2003. In addition, Mr. Krol elected to receive his pro-rata cash
remuneration in the form of an award of 777 options (100% vested but not
exercisable until August 6, 2003). These options have an exercise price of
$12.97. Under the terms of the director restoration option described below,
Mr. Walsh received 13,105 options on December 18, 2001 with an exercise price of
$56.09 and an expiration date equal to that of the options they restored.
Mr. Foss also received a restoration option grant for 10,471 options on
September 21, 2001 with an exercise price of $40.77 and an expiration date equal
to that of the options they restored. Mr. Slusser also received a restoration
option grant for 2,467 options on December 13, 2001 with an exercise price of
$54.35 and expiration date equal to that of the options they restored. Upon his
departure from the Board effective February 21, 2002, the grant of 20,000
options for Mr. Walsh was cancelled.

    All options are granted under the Tyco International Ltd. Long Term
Incentive Plan and, except in the case of restoration options, have a term of
ten years from date of grant. Each option provides for an automatic grant of a
restoration option to the extent the director uses Tyco common shares towards

                                       28
<Page>
payment of his/her option exercise price. Restoration options have a term ending
on the expiration date of the options they restore.

    In fiscal 2002, some of the Board members had taxable compensation for
personal use of company aircraft. If the personal use was to take their spouse
to a Board meeting at the invitation of Tyco, Tyco approved the gross-up of this
income; otherwise, the amount was not grossed-up. The taxable income amounts are
as follows: Mr. Berman: $1,466.58 and gross-up of $542.43; Mr. Foss: $3,978.99
and gross-up of $443.71; Ms. Lane: $1,348.57 and gross-up of $498.79; and
Mr. Slusser: $600.37 and gross-up of $222.05.

    For the period from June 3, 2002 through the appointment of Tyco's new
Chairman and Chief Executive Officer in July 2002, Mr. Fort assumed
responsibility for the duties of an interim chief executive officer. Mr. Fort
was not an employee on Tyco's payroll, but the Board voted to pay Mr. Fort
$600,000 for his service and for his on-going work during a transition period
after Mr. Breen was named Chief Executive Officer.

    Mr. Berman was a director of Tyco until December 5, 2002. From March 1, 2000
through July 31, 2002, Mr. Berman was engaged to render legal and other
services. During this period, Tyco compensated Mr. Berman at an annual rate of
$360,000 and provided Mr. Berman with health benefits, secretarial assistance, a
cell phone and electronic security services for his homes.

FISCAL 2003 COMPENSATION

    Board remuneration for fiscal 2003 was set at $80,000, payable at the
monthly rate of $6,666.66 for each full month on the Board and pro-rated for the
number of days on the Board if the director begins or ends Board service during
the month, and 20,000 stock options that will vest one year after issuance. On
October 2, 2002, Mr. Krol was granted a stock option with respect to
compensation for fiscal 2003 at an exercise price of $13.45 per share. On
January 15, 2003, Messrs. McDonald, Buckley, York and Gordon received stock
options for fiscal 2003 at an exercise price of $17.80. Directors who join the
Board after January 15, 2003 will be granted their stock options with respect to
compensation for fiscal 2003 on the date they become Board members. All options
granted to Board members will have an exercise price equal to the average of the
high and low sale price of a Tyco common share reported for the date of grant.
Directors who are not standing for re-election were not given option grants for
fiscal 2003. The Board may in the future determine to grant additional options
or other equity compensation as a component of director compensation and/or to
adjust directors' cash remuneration.

FISCAL 2002 BOARD MEETINGS

    The Board of Directors held sixteen (16) meetings during fiscal 2002. During
the periods that he or she served, each director attended at least 75% of the
aggregate of: (1) the number of Board meetings held during the period in which
he or she was a director and (2) the number of meetings of all committees on
which he or she served.

BOARD COMPENSATION COMMITTEE REPORT ON EXECUTIVE COMPENSATION

    Fiscal 2002 was a difficult, yet pivotal, year for Tyco. On June 3, 2002, L.
Dennis Kozlowski resigned as Chairman and Chief Executive Officer of Tyco on the
eve of his indictment. On September 17, 2002, Tyco reported on a Form 8-K that
its former Chief Executive Officer, Chief Financial Officer, and Chief Corporate
Counsel had engaged in improper conduct that was concealed from the Board and
this Committee. The actions taken by, and the compensation of, Tyco's former
management have been the subject of both internal and external investigations.
Actions taken by Tyco to address these issues include legal proceedings against
its former Chief Executive Officer and Chief Financial Officer for breach of
fiduciary duties, fraud and other wrongful conduct, and against the former Chief
Corporate Counsel for breach of fiduciary duty and other wrongful conduct,
including using company funds for personal gain.

                                       29

    During fiscal 2002 and the beginning of fiscal 2003, an entirely new senior
corporate management team has been put in place. Edward D. Breen became Tyco's
Chairman, President and Chief Executive Officer effective July 25, 2002. The
Board selected Mr. Breen for, among other reasons, his record of proven
leadership, as well as his ability to handle complex and difficult business
challenges, to create effective problem-solving strategies, and to take decisive
action. Subsequent to Mr. Breen's joining Tyco, the following executive officers
also joined Tyco during fiscal 2002: David J. FitzPatrick, Executive Vice
President and Chief Financial Officer; William B. Lytton, Executive Vice
President and General Counsel; and Eric M. Pillmore, Senior Vice President,
Corporate Governance. In addition, Mackey J. McDonald, who was appointed a
director of Tyco on November 18, 2002, has been named by the Board to be the new
chair of the Compensation Committee. The Compensation Committee is confident
that the new leadership team will restore Tyco as a strong, viable company that
adheres to strict corporate governance.

COMPENSATION FOR FISCAL 2002

    During fiscal year 2002, the elements of Tyco's compensation program for its
senior executives were base salary, annual incentive bonus opportunity and
long-term equity-based incentive compensation. The annual incentive bonus
opportunities for division presidents were based upon the Compensation
Committee's and senior management's assessment of the respective divisions'
financial performance, evaluated in terms of earnings before interest and taxes
("EBIT") and free cash flow. As in prior years, a portion of annual bonuses was
paid in shares and a portion was payable in cash. Cash bonuses were determined
after Tyco filed its Annual Report on Form 10-K for fiscal 2002 so that final
bonus determinations reflected any required adjustments to the financial
statements. In some instances, annual bonuses were reduced by the Compensation
Committee in consultation with new management based on subjective assessments of
performance. The Compensation Committee also approved or awarded certain
discretionary bonuses to division executives in recognition of special
achievement. The cash bonuses paid to the new senior corporate management team
for fiscal 2002 were primarily in the form of (i) sign-on bonuses designed to
compensate these executives for awards and other compensation that they
forfeited under their prior employers' programs when they determined to join
Tyco, and (ii) minimum guaranteed bonuses under their employment agreements that
were provided in recognition of the fact that there may be a delay before
long-term corporate performance reflects their contributions to Tyco.

    In 2002, the Compensation Committee utilized a number of long-term
equity-based incentive compensation arrangements. The Compensation Committee
believes equity-based incentive compensation ties executive interests to
shareholder interests in several ways: (i) the lapse of restrictions on
restricted shares and the number of shares earned can be correlated to
achievement of performance objectives, (ii) the use of a multi-year vesting
schedule for equity awards encourages executive retention and emphasizes
long-term growth, and (iii) the value of the equity award is ultimately
determined by the future performance of Tyco as reflected by its share price. In
addition, the Compensation Committee believes that by paying a significant
portion of management's compensation in Tyco equity, management has a strong
interest in increasing shareholder value. Stock option and restricted share
awards for executive officers and divisional presidents in fiscal 2002 are
generally reflective of salary level, position and individual contribution,
taking into account share awards to executives at comparable positions at other
large diversified manufacturing companies. For awards to new executive officers
who were hired during the year, option grants consisted of both sign-on grant
and annual grant components, based on the same considerations reflected in their
bonuses. In addition, in lieu of restricted share grants, Tyco granted deferred
share units to Messrs. Breen, Fitzpatrick and Lytton. As explained further under
"Chief Executive Officer Compensation" below, these awards are designed to focus
management on both obtaining and maintaining long-term corporate performance.
The Compensation Committee exercises subjective judgment and discretion in
applying the above criteria and its general compensation objectives and policies
to determine individual equity awards.

                                       30
<Page>
    The Compensation Committee has retained outside consultants to complete a
formal review of compensation levels and strategy that will take into account
current cash compensation, annual incentive bonuses, and long-term equity-based
incentive compensation. Tyco is committed to hiring and retaining the best
executive talent, and paying competitively to keep and motivate its talented
executives when such pay is merited by performance.

CHIEF EXECUTIVE OFFICER COMPENSATION

    In connection with Mr. Breen's employment, Tyco entered into the employment
agreement described on page 44. The terms and conditions of the employment
agreement were unanimously approved by the Compensation Committee and Board
after consideration of Mr. Breen's qualifications and experience, his previous
compensation levels, foregone awards and other compensation at his prior
employer, and the competitive marketplace for executive talent at large
industrial companies. The Compensation Committee and Board also took into
consideration the unique challenges facing Tyco's new Chief Executive Officer,
and the need to name an executive who had both a strong record of success and
whose reputation for personal and professional integrity were unassailable.
Under the employment agreement, Mr. Breen is entitled to an annual salary of
$1,500,000, and for fiscal 2002 to a pro-rated bonus of $279,452. In addition,
Mr. Breen received a one-time sign-on bonus of $3,500,000. For fiscal 2003,
Mr. Breen is entitled to a minimum cash bonus of $1,500,000. Mr. Breen was also
provided the equity awards described on page 40 of 7,350,000 stock options, with
vesting of 3,350,000 options over a period of three years and the balance over a
period of five years, and 1,350,000 deferred share units, with vesting of
350,000 units over a period of three years and the balance over a period of five
years. The vesting of equity awards over a period of three to five years is
designed to encourage retention and an emphasis on long-term growth. In
addition, Mr. Breen's options were granted with an exercise price approximately
18% above the average of the high and low sale price reported for the date of
grant, to further the goal of long-term stock price appreciation. The deferred
share units awarded to Mr. Breen and other members of senior management also are
designed to further the goal of aligning Tyco's senior management team with
long-term shareholders. Once the deferred share units have vested, they are
settled through the issuance of shares only upon the executive's termination of
employment, thereby motivating management to both achieve and maintain long-term
stock price performance. The Compensation Committee believes the substantial
equity awards were warranted and necessary in order to attract an executive of
the highest caliber, and to provide a strong incentive to increase shareholder
value.

    For fiscal 2002, Mr. Kozlowski was paid $1,327,500 pursuant to the Retention
Agreement described on page 48. Mr. Kozlowski was also granted the equity award
described on page 40, which include a grant of 600,000 performance-based
restricted shares on October 1, 2001, and, in accordance with the Retention
Agreement, a grant of 800,000 time-based restricted shares on January 22, 2002.
Mr. Kozlowski forfeited 1,105,065 of these shares upon termination of his
employment. Mr. Kozlowski also received an option grant for 3,000,000 shares on
October 1, 2001, which was forfeited on his termination of employment. These
payments and awards were made before the improper conduct of the former Chief
Executive Officer and his related misuse of company funds became known to
members of the Compensation Committee.

    Some of the amounts and benefits received or obtained by Mr. Kozlowski and
by Mark H. Swartz, our former Chief Financial Officer, were obtained without
authorization from the Board or this Compensation Committee, or may have been
obtained without proper documentation under then-existing company policies. Tyco
has filed a civil complaint against Mr. Kozlowski for breach of fiduciary duty
and other wrongful conduct. The action alleges that Mr. Kozlowski
misappropriated millions of dollars from our Key Employee Loan Program and
relocation program; awarded millions of dollars in unauthorized bonuses to
himself and other Tyco employees; engaged in improper self-dealing real estate
transactions involving Tyco assets; and conspired with certain other former Tyco
employees in committing these acts. Tyco also has filed an arbitration claim
against Mr. Swartz. The action alleges that Mr. Swartz breached his fiduciary

                                       31
<Page>
duties and otherwise engaged in wrongful conduct relating to his employment by
Tyco and misappropriated Tyco funds and other assets and seeks to recover from
Mr. Swartz all damages suffered by Tyco as a result of such breach, wrongful
conduct and misappropriation. In these proceedings, we are seeking disgorgement
of all amounts received by Messrs. Kozlowski and Swartz during the periods shown
in the SUMMARY COMPENSATION TABLE. More information with respect to these
unauthorized payments and benefits was reported on September 17, 2002 in a
Current Report on Form 8-K and is set forth in Item 3 "Legal Proceedings" of our
Annual Report on Form 10-K for the fiscal year ended September 30, 2002 and in
the caption entitled "Related Party Transactions" below.

    For the period of June 3, 2002 to July 25, 2002, John F. Fort III, who was
serving as Lead Director of the Board, also acted as interim chief executive
officer of Tyco. Mr. Fort was not an employee on Tyco's payroll but received
compensation from Tyco of $600,000 for serving in this position and for
providing subsequent transition services.

CERTAIN OTHER EXECUTIVE OFFICERS

    In connection with recruiting and hiring Messrs. FitzPatrick, Lytton and
Pillmore, Tyco entered into the employment agreements described starting on page
44. The terms and conditions of the employment agreements were unanimously
approved by the Compensation Committee and the Board, and by Mr. Breen. The
employment agreements provide these executives with sign-on bonuses and equity
awards for the reasons noted above.

APPLICABLE TAX CODE PROVISION

    Section 162(m) of the Internal Revenue Code limits the amount of
compensation that may be deducted by Tyco with respect to each named officer to
$1,000,000, except that this limitation does not apply to compensation that is
considered to be performance-based and does not apply to an executive after the
executive ceases to be employed. Tyco's Long Term Incentive Plan, as amended
May 12, 1999 and approved by Tyco's shareholders, has been structured so that
compensation realized by executives upon their exercise of options granted under
that plan can qualify as performance-based compensation. The employment
agreements for Messrs. Breen, FitzPatrick, Lytton and Pillmore provide for
minimum guaranteed bonuses for fiscal 2003 and other awards and payments that
are not considered performance-based, which, as noted above, the Compensation
Committee believes were necessary to attract these executives to Tyco. The
Compensation Committee believes that in light of the circumstances affecting
Tyco in fiscal 2002, and taking into account the non-deductibility of those
arrangements, it was in the best interest of Tyco and its shareholders to pay
executive compensation the Committee deemed necessary and appropriate to attract
outstanding executives who are well equipped to address the challenges facing
Tyco.

COMPENSATION POLICY FOR FISCAL 2003 AND SUBSEQUENT YEARS

    The Board is taking this opportunity to initiate a policy of periodically
reviewing, evaluating and enhancing Tyco's governance processes. As part of this
process, it is expected that the Board will review and update the written
charter for the Compensation Committee that will clearly set forth the
Committee's objectives and responsibilities. The Compensation Committee is
already in the process of reviewing Tyco's overall compensation philosophy, and
proposing new short-term and long-term incentive compensation programs for
senior executives of Tyco and its subsidiaries that reflect the values and goals
of the new Tyco. Consistent with this overall philosophy, it is expected that
significant changes will be implemented for fiscal 2003. While overall
compensation will continue to be competitive on an industry-wide basis, it is
anticipated that there will be a reduction in the targeted level of annual cash
incentive awards.

    The Compensation Committee will be guided by the principle that its total
compensation program must be competitive, and must provide significant rewards
for outstanding financial performance while establishing clear consequences for
under-performance. It is anticipated that future bonus awards for divisional
executives will take into account Tyco's overall performance as well as
divisional and individual objectives and that long-term awards will be aligned
to shareholder return. Annual bonus and long-term awards for senior corporate
management will take into account not only objective financial goals and
enhanced shareholder value, but also individual performance goals that reinforce
core values of the new Tyco.

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

    Messrs. Foss, Pasman, Slusser and Welch served as members of the
Compensation Committee during fiscal 2002. Mr. Foss is the owner of a corporate
aircraft that Tyco leased from him starting in May 2001 after seeking
competitive bids, of which Mr. Foss's bid was considered the most competitive
given anticipated usage. Tyco paid Mr. Foss and a company of which he is
president an aggregate of $587,000 in lease payments for Tyco's use of the
aircraft and its pilots in fiscal 2002. These leasing arrangements were
terminated as of September 30, 2002.

EXECUTIVE COMPENSATION

SUMMARY COMPENSATION TABLE

    The table below presents the annual and long-term compensation for services
in all capacities to Tyco and its subsidiaries for the periods shown for our new
senior management team, our executives who oversee our business segments and
certain former executive officers (collectively, the "Named Officers"). As
detailed below, some of the amounts and benefits received or obtained by L.
Dennis Kozlowski, our former Chief Executive Officer, and Mark H. Swartz, our
former Chief Financial Officer, were obtained without authorization from our
Board or Compensation Committee, and thus do not constitute compensation
properly paid to such former executive officers for services to Tyco and its
subsidiaries, or may have been obtained without proper documentation under then
existing company policies. More information with respect to these unauthorized
payments and benefits was reported on September 17, 2002 in a Current Report on
Form 8-K and is set forth in Item 3 "Legal Proceedings" of our Annual Report on
Form 10-K for the fiscal year ended September 30, 2002 and in the caption
entitled "Related Party Transactions" below.

- ------------------------

(1) Under the Tyco Deferred Compensation Plan, the total amount of salary and
    bonus that has been deferred for fiscal 2002 is as follows:
    Mr. Boggess--$325,276; Mr. Meelia--$231,490; and Mr. Swartz-$564,375 (which
    was distributed to Mr. Swartz pursuant to his severance agreement described
    below under the subcaption entitled "--Employment, Retention and Severance
    Agreements"). The amounts shown in the table include the amounts deferred.
    We are seeking disgorgement of all amounts received by Mr. Swartz during the
    periods shown in this table. See footnote 16 below.

(2) The salaries shown for Messrs. Breen, FitzPatrick, Lytton and Pillmore are
    the amounts paid or accrued from the date of hire through September 30,
    2002.

(3) The bonus amounts shown in the table for Messrs. Breen and Pillmore include
    a sign-on bonus and a pro-rated fiscal 2002 bonus, each of which was paid
    pursuant to the terms of their employment agreement. The bonus amounts shown
    in the table for Messrs. FitzPatrick and Lytton are sign-on bonuses.
    Mr. Pillmore's sign-on bonus includes a gross-up of $55,763 so that the net
    payment was $100,000. The bonus amounts shown for Messrs. Boggess, Mead,
    Meelia and Dr. Gromer for fiscal 2002 reflect payments based on the
    performance during fiscal 2002 of the segment headed by the executives, and,
    in the cases of Mr. Boggess and Dr. Gromer, as reduced by the Compensation
    Committee in consultation with new management. A portion of the bonus
    amounts for Messrs. Boggess, Mead, Meelia and Dr. Gromer for fiscal 2002 was
    paid in the form of Tyco common shares. The number of common shares earned
    for fiscal 2002 was based on quarterly business segment performance. The
    total number of bonus common shares earned by each business segment
    president for fiscal 2002 is as follows: Mr. Boggess--22,631 common shares;
    Dr. Gromer--25,610 common shares; Mr. Mead--29,185 common shares; and
    Mr. Meelia--47,702 common shares. The amounts listed in the table include
    the fair market value of the common shares on the dates such common shares
    vested ($47.945 on January 15, 2002; $21.585 on April 25, 2002; $11.43 on
    July 23, 2002 and $17.80 on January 15, 2003). Dr. Gromer's bonus for fiscal
    2001 includes a bonus of $4,000,000 paid in November 2001 and 35,000 shares
    vested in January 2002 that were initially categorized as a special bonus
    for retention purposes and for managing a significant cost reduction program
    for Tyco's electronics segment during fiscal 2001, but was part of his
    fiscal 2001 performance bonus. The value of the share bonus is based on the
    fair market value of shares on January 30, 2002 of $31.645.

(4) Includes various perquisites and personal benefits if the amount exceeds
    $50,000 in any year, in addition to specifically noting tax gross-up
    payments and interest credited on deferred compensation in excess of 120% of
    the applicable federal long-term rate. Messrs. Breen, FitzPatrick and
    Pillmore received tax gross-ups for living expenses in New York (see ALL
    OTHER COMPENSATION column). The amounts shown represent their respective
    estimated tax gross-ups for the period through the end of fiscal 2002. The
    amounts shown in the table for fiscal 2002 include the personal use of
    company cars and aircraft of $107,114 for Mr. Kozlowski and $100,827 for
    Mr. Swartz valued at the rates prescribed under applicable IRS regulations;
    interest credited on deferred compensation in excess of 120% of the
    applicable federal long-term rate of $160,136 for Mr. Boggess, $15,097 for
    Mr. Mead, $211,158 for Mr. Meelia, $166,464 for Mr. Kozlowski and $101,347
    for Mr. Swartz; tax gross-ups related to perquisites of $4,533 for
    Mr. Boggess and $22,631 for Mr. Meelia; reimbursement for New York state
    taxes of $450,000 for Mr. Kozlowski and $419,287 for Mr. Swartz; tax
    gross-ups on a portion of the executive life insurance premiums shown in the
    ALL OTHER COMPENSATION column of $915,608 for Mr. Kozlowski and $480,534 for
    Mr. Swartz; use and maintenance of apartments in New York in the amount of
    $649,217 for Mr. Kozlowski and $130,661 for Mr. Swartz; and other
    miscellaneous perquisites or other personal benefits for Mr. Kozlowski of
    $430,730 and for Mr. Swartz of $39,241. We are seeking disgorgement of all
    amounts received by Mr. Kozlowski and Mr. Swartz during the periods shown in
    this table. See footnotes 15 and 16 below.

                                       35

(5) Amounts set forth in the restricted share awards column include grants of
    restricted shares and deferred share units. Under the terms of his
    employment agreement, Mr. Breen was granted awards of deferred share units
    ("DSU") corresponding to 1,000,000 and 350,000 common shares. The larger
    award vests one-fifth on each anniversary of the grant date and the other
    award vests one-third on each anniversary of the grant date.
    Messrs. FitzPatrick and Lytton were also awarded DSU's corresponding to
    200,000 and 150,000 common shares respectively. These awards vest one-third
    on each anniversary of the grant date. DSU's are credited with dividend
    equivalents on the same date and amount as dividends are paid on Tyco common
    shares. The value of the dividend equivalents will be used to credit
    additional DSU's to the executive's DSU account. DSU's are settled by
    issuance of common shares upon the executive's termination of employment.
    The amount listed in the table reflects the fair market value of the DSU's
    on the date they were granted (based on a share price of $8.465 on July 25,
    2002 for Mr. Breen, $16.285 on September 18, 2002 for Mr. FitzPatrick, and
    $13.765 on September 30, 2002 for Mr. Lytton). Mr. Pillmore was granted
    40,000 restricted shares vesting one-third on each of January 1, 2003,
    January 1, 2004, and January 1, 2005. The amount listed in the table
    reflects the fair market value of the common shares on the date they were
    granted (based on a common shares price of $12.395 on August 12, 2002).
    Dividends are payable on the restricted shares. The fiscal year-end value of
    DSU's and restricted share holdings calculated using the share price of
    $13.765, which is the average of the high and low sale price of Tyco common
    shares on September 30, 2002, is $18,582,750 for Mr. Breen, $2,753,000 for
    Mr. FitzPatrick, $2,064,750 for Mr. Lytton and $550,600 for Mr. Pillmore.
    Messrs. Kozlowski and Swartz, respectively, were granted 600,000 and 300,000
    performance-based restricted shares on October 1, 2001. Common shares were
    issued under the restricted share program whereby specific performance
    criteria determine the number of common shares that vest for the fiscal
    year. If the performance criteria are not met, resulting in some or all of
    the common shares not being earned (I.E., not vesting) within a three-year
    period, those common shares are forfeited and must be returned to Tyco. In
    addition, in accordance with their retention agreements, Messrs. Kozlowski
    and Swartz were granted 800,000 and 500,000 time-based restricted shares on
    January 22, 2002. The value shown is the fair market value on the dates of
    the grants ($45.105 for the October 1, 2001 grant and $49.91 for the
    January 22, 2002 grant). Mr. Kozlowski forfeited 1,105,065 of these common
    shares upon termination of his employment. Under the terms of his retention
    agreement, Mr. Swartz would have vested in all remaining common shares upon
    a resignation for good reason (as defined therein). We are seeking
    disgorgement of all amounts received by Messrs. Kozlowski and Swartz during
    the periods shown in the table. See footnotes 15 and 16 below.

(6) The total amounts shown in the table for fiscal 2002 for Messrs. Breen,
    FitzPatrick and Pillmore represent amounts paid by Tyco or reimbursed to
    these executives for living expenses in the New York area while working in
    the New York office. The amounts shown in the table for Messrs. Boggess,
    Mead, Meelia, Kozlowski and Swartz reflect Tyco contributions made on their
    behalf under Tyco's qualified and non-qualified defined contribution plans,
    as follows:

    The amount shown in the table for Mr. Boggess also includes an Employee
Stock Purchase Plan company match of $2,700, taxable life insurance of $422 and
the economic value of split dollar life insurance of $384. The amount shown in
the table for Mr. Mead also includes an Employee Stock Purchase Plan company

<Page>
Employee Stock Purchase Plan company match of $1,950 and taxable life insurance
premium of $1,697. The amounts shown in the table for Messrs. Kozlowski and
Swartz also include executive life insurance premiums of $5,136,419 and
$2,610,452, respectively. In addition, in fiscal 2002 Mr. Swartz received a lump
sum payment of $24,554,078, which represented a buy-out of the future funding
obligation under the executive life insurance policy (See "Former Executive Life
Insurance" on page 44), $756,250 in consulting fees and $9,075,000 in severance.
See the description of Mr. Swartz's severance agreement under the subcaption
"Employment, Retention and Severance Agreements" on page 49. We are seeking
disgorgement of all amounts received by Messrs. Kozlowski and Mr. Swartz during
the periods shown in the table. See footnotes 15 and 16 below.

(7) Mr. Breen became Chairman and Chief Executive Officer of Tyco on July 25,
    2002.

(8) Mr. FitzPatrick became Executive Vice President and Chief Financial Officer
    of Tyco on September 18, 2002.

(9) Mr. Lytton became Executive Vice President and General Counsel of Tyco on
    September 30, 2002.

(10) Mr. Pillmore became Senior Vice President of Corporate Governance of Tyco
    on August 12, 2002.

(11) Dr. Gromer's salary and bonus are set in US Dollars, but are converted into
    and paid in Euros. For fiscal 2002, Dr. Gromer's base salary was $695,500,
    which at the time it was set converted into E790,409.

(12) Mr. Mead was named as an executive officer in July 2002. The amount in the
    table reflects his compensation for all of fiscal 2002.

(13) Executive compensation reported for fiscal 2000 did not include
    compensation paid to, and amounts received or obtained by, Mark A. Belnick,
    our former Executive Vice President and Chief Corporate Counsel. Tyco has
    alleged that Messrs. Kozlowski and Belnick conspired to manipulate internal
    documents so as to avoid disclosing Mr. Belnick's compensation for fiscal
    2000. Had such amounts been included in our proxy statement for fiscal 2000,
    they would have been as follows: Salary--$737,500; Bonus--$4,000,000; Other
    Annual Compensation--$200,254 (including executive life insurance premiums
    of $2,769 and a tax gross-up on forgiveness of mortgage loans of $197,485);
    Restricted Share Grant $14,009,000 (representing the value of an aggregate
    of 300,000 restricted shares calculated using the average of the high and
    low sale prices of Tyco common shares on the dates of grant); Common Shares
    Underlying Options--211,012 Tyco options and 100,000 options to purchase
    shares of Tycom Ltd.; and All Other Compensation--$293,115 (including a
    qualified plan contribution of $8,500 and a non-qualified plan contribution
    of $102,750, forgiveness on mortgage loans in the amount of $179,990 and an
    award of 50 common shares having a fair market value of $1,875 on the date
    of grant). We have filed a civil complaint against Mr. Belnick for breach of
    fiduciary duty and other wrongful conduct. The action alleges that
    Mr. Belnick solicited and accepted cash and stock bonuses without Board
    approval; took interest-free loans from our relocation program without Board
    approval; failed to disclose to the Board and to the SEC his retention
    agreement and compensation; failed to advise the Board of the improper
    conduct of other officers; refused to cooperate with internal
    investigations; and engaged in other improper conduct. We are seeking
    disgorgement of all amounts received by Mr. Belnick during such period. More
    information with respect to this action was reported on September 17, 2002
    in a Current Report on Form 8-K and is set forth in Item 3 "Legal
    Proceedings" of our Annual Report on Form 10-K for the fiscal year ended
    September 30, 2002 and in the caption entitled "Related Party Transactions"
    below.

(14) Mr. Fort was Tyco's Lead Director until August 2002. He assumed
    responsibility for the duties of an interim chief executive officer from
    June 3, 2002 until the appointment of Tyco's new Chairman and Chief
    Executive Officer in July 2002 and performed other services during a
    transition period from July 25, 2002 to September 30, 2002. Mr. Fort was not
    an employee on Tyco's payroll, but the Board voted to compensate Mr. Fort at
    the rate of $150,000 per month for each full or partial month he

                                       37
<Page>
    acted as an interim chief executive officer or provided transition services.
    The amount shown in the table, which does not include the Board remuneration
    described in "Directors' Compensation" on page 28, represents the amount
    paid to Mr. Fort in this capacity.

(15) Mr. Kozlowski ceased to be employed by Tyco in June 2002. We have filed a
    civil complaint against Mr. Kozlowski for breach of fiduciary duty and other
    wrongful conduct. The action alleges that Mr. Kozlowski misappropriated
    millions of dollars from our Key Employee Loan Program and relocation
    program; awarded millions of dollars in unauthorized bonuses to himself and
    certain other Tyco employees; engaged in improper self-dealing real estate
    transactions involving our assets; and conspired with certain other former
    Tyco employees in committing these acts. We are seeking disgorgement of all
    amounts received by Mr. Kozlowski during the periods shown in the table.
    More information with respect to this action was reported on September 17,
    2002 in a Current Report on Form 8-K and is set forth in Item 3 "Legal
    Proceedings" our Annual Report on Form 10-K for the fiscal year ended
    September 30, 2002 and in the caption entitled "Related Party Transactions"
    below.

(16) Mr. Swartz ceased to be employed by Tyco in August 2002. We have filed an
    arbitration claim against Mr. Swartz. The action alleges that Mr. Swartz
    breached his fiduciary duties and otherwise engaged in wrongful conduct
    relating to his employment by Tyco and misappropriated Tyco funds and other
    assets and seeks to recover from Mr. Swartz all damages suffered by Tyco as
    a result of such breach, wrongful conduct and misappropriation. We are
    seeking disgorgement of all amounts received by Mr. Swartz during the
    periods shown in the table. More information with respect to this
    arbitration claim was reported on October 8, 2002 in a Current Report on
    Form 8-K and is set forth in Item 3 "Legal Proceedings" of our Annual Report
    on Form 10-K for the fiscal year ended September 30, 2002 and in the caption
    entitled "Related Party Transactions" below.

(17) Does not include unauthorized bonuses of $700,000 received by
    Mr. Kozlowski and $350,000 received by Mr. Swartz in fiscal 2001 for which
    Tyco has brought claims against Mr. Kozlowski and Mr. Swartz. See footnotes
    15 and 16 above.

(18) The amount in the table reflecting Mr. Meelia's OTHER ANNUAL COMPENSATION
    for fiscal 2000 has been revised. The amounts shown include, among other
    items, a cash payment of the unused portion of a perquisite entitlement of
    $21,031, a tax gross-up on such entitlement of $16,838 and the personal use
    of a company car and related maintenance of $20,218, as well as interest
    credited on deferred compensation in excess of 120% of the applicable

    life insurance premium of $1,571,190 for fiscal 2001; use and maintenance of

    $485,634 for fiscal 2000; imputed interest of $16,528 in fiscal 2001 and
    $1,053,713 in fiscal 2000; and other miscellaneous perquisites or other
    personal benefits of $478,192 for fiscal 2001 and $533,914 for fiscal 2000.
    The amounts shown do not include unauthorized tax gross-ups of $6,768,338 in

    and for which Tyco has brought a claim against Mr. Kozlowski. See footnote
    15 above.

- ------------------------------

(1) Certain options granted to the Named Officers include a restoration feature
    whereby participants receive options to replace exercised options or common
    shares if the common shares or share proceeds (i) are used to pay the
    exercise price of stock options, (ii) are applied to satisfy tax withholding
    obligations or repay indebtedness to Tyco or (iii) are sold by trusts for
    tax planning purposes ("restoration options"). In certain cases, restoration
    options are granted to an executive who has sold vested restricted shares to
    Tyco or a subsidiary thereof, enabling the executive to maintain the level
    of his equity interest in Tyco. The Restoration Option Program was
    discontinued by Tyco during fiscal 2002.

(2) Represents the percentage of all options granted in fiscal 2002 under Tyco's
    option plans: the LTIP and the Tyco International Ltd. Long Term Incentive
    Plan II.

(3) Options were granted at an exercise price equal to the fair market value of
    the Tyco common shares on the date of grant (except for options granted to
    Mr. Breen, which were granted with an exercise price above the average high
    and low sale price). Fair market value was determined based on either the
    average of the high and low reported sale price of Tyco common shares on the
    date of grant, the volume weighted average sale price, the closing price,
    the low reported sale price of Tyco common shares on the date of grant or,
    in the case of restoration options, the sale price of the Tyco common shares
    that gave rise to such grant.

(4) Tyco chose to use the Black-Scholes option pricing model to value the
    options. The Black-Scholes model is a method of calculating the hypothetical
    value of the options on the date of grant. With the exception of
    Mr. Breen's option grants, all options were granted at an exercise price
    equal to the fair market value of Tyco's common shares on the date of grant
    (see footnotes 3

                                       40
<Page>
    and 14). The following assumptions were used in calculating the
    Black-Scholes values: The value shown on the table for the options: expected
    life of five years (except for Mr. Kozlowski, for which the actual life is
    until June 3, 2003--see footnote 11); interest rates of 2.24%-4.72%; assumed
    annual volatility of underlying common shares of 39.15%-67.56%; and the
    vesting schedule listed for the option grant. For all of the above, the
    interest rates represent the yield of a zero coupon Treasury strip with a
    maturity date similar to the assumed exercise price; and the assumed annual
    volatility and dividend yield of underlying common shares was calculated
    based on 36 months of historical Tyco share price movement and the dividend
    payments. In addition, the value has been discounted for risk of forfeiture
    based on the vesting schedule of the grant, by 3% for options which vest
    after one year, by 8.7% for options which vest after three years, by 5.9%
    for options which vest in equal installments over three years and by 8.6%
    for options which vest in equal installments over five years.

(5) Options vest one-third per year on each anniversary of the grant date,
    except for Mr. Breen's grant of options on 4,000,000 common shares, which
    vest 20% per year on each anniversary of the grant date. Option vesting is
    subject to acceleration upon the executive's termination of employment by
    Tyco other than for "cause" or following a "change in control" or by the
    executive for "good reason" (in each case as defined in the executive's
    employment agreement or option agreement) and in the case of Mr. Breen, upon
    a change in control. Options have a ten year term, subject in certain cases
    to earlier expiration following termination of employment.

(6) Options vest 100% on the third anniversary of the grant date. Options have a
    ten year term, subject in certain cases to earlier expiration following
    termination of employment.

(7) Represents restoration options which are fully vested on the grant date,
    granted at fair market value and have a ten year term, subject in certain
    cases to earlier expiration following termination of employment.

(8) Options vests one-third per year on each anniversary of the grant date.
    Options have a ten year term, subject in certain cases to earlier expiration
    following termination of employment. In the case of Mr. Swartz, we are
    seeking disgorgement of all amounts received by Mr. Swartz during the
    periods shown in the SUMMARY COMPENSATION TABLE. See footnote 16 to SUMMARY
    COMPENSATION TABLE above.

(9) The portion of Dr. Gromer's options that are allocated to his Swiss
    compensation expire ten years and one month from the date of grant.

(10) Option vests one-third per year on each anniversary of the grant date.
    Option has a ten-year term, subject in certain cases to earlier expiration
    following termination of employment. The value of $0 shown on the table
    reflects that this option grant was cancelled as a result of
    Mr. Kozlowski's termination of employment. The grant date present value for
    this option grant using a term of three years (the original estimated period
    of exercise) was $49,560,000. We are seeking disgorgement of all amounts
    received by Mr. Kozlowski during the periods shown in the SUMMARY
    COMPENSATION TABLE. See footnote 15 to SUMMARY COMPENSATION TABLE above.

(11) Represents restoration options which are fully vested on the grant date but
    not exercisable for a period of two months from the grant date, granted at
    fair market value and have a ten year term, subject in certain cases to
    earlier expiration following termination of employment. The values in the
    table shown for these grants reflect their actual expiration date of
    June 3, 2003, which is a shortened term due to Mr. Kozlowski's termination
    of employment. The grant date present value for these options using a term
    of three years (the original estimated period of exercise) would be
    $3,722,690, $483,800, and $4,577,074, respectively. We are seeking
    disgorgement of all amounts received by Mr. Kozlowski during the periods
    shown in the SUMMARY COMPENSATION TABLE. See footnote 15 to SUMMARY
    COMPENSATION TABLE above.

(12) Under the terms of his retention agreement, Mr. Swartz would have vested in
    all options upon a resignation for good reason (as defined therein). We are
    seeking disgorgement of all amounts received by Mr. Swartz during the
    periods shown in the table. See footnote 16 to SUMMARY COMPENSATION TABLE
    above.

(13) Represents restoration options which are fully vested on the grant date but
    not exercisable for a period of two months from the grant date, granted at
    fair market value and have a ten year term, subject in certain cases to
    earlier expiration following termination of employment. We are seeking
    disgorgement of all amounts received by Mr. Swartz during the periods shown
    in the SUMMARY COMPENSATION TABLE. See footnote 16 to SUMMARY COMPENSATION
    TABLE above.

(14) Options granted with an exercise price of $10.00, which is $1.535 (18.13%)
    higher than the average high and low sale price reported for the grant date.

RETIREMENT PLANS

    Messrs. Breen, FitzPatrick, Lytton, Pillmore and Dr. Gromer participate in
defined benefit or actuarial retirement plans ("pension plans") maintained by
Tyco or a subsidiary, as described below.

    As part of his employment agreement, Mr. Breen is provided with a
Supplemental Retirement Benefit. Commencing at age 60, Mr. Breen will receive a
monthly annuity based upon 50% of his highest average earnings from Tyco during
any consecutive 36-month period within the 60-month period prior to his
termination. This monthly annuity is offset by any benefits provided under a
defined benefit plan maintained by any prior employer and his benefits
attributable to the company match under Tyco's 401(k) and supplemental plans,
adjusted to reflect earnings. At his current pay level, Mr. Breen will have a
lifetime benefit of $95,782 per month, commencing at his normal retirement age
of 60. One-half of this amount will continue to his surviving spouse in the
event of his death. Retirement benefits are available at an earlier age but
would be reduced by .25% for each month that the benefit commences prior to age
60 and could result in a forfeiture of any unvested portion. Mr. Breen may elect
to receive the actuarial equivalent of his annuity in the form of a lump sum
payment.

    As part of his employment agreement, Mr. FitzPatrick is provided with a
Supplemental Retirement Benefit. Commencing at age 62, Mr. FitzPatrick will
receive a monthly annuity based upon 2% multiplied by his years of service plus
an additional 10% multiplied by his highest average earnings from Tyco during
any consecutive 36-month period within the 60-month period prior to his
termination. This monthly annuity is offset by any benefits provided under a
defined benefit plan maintained by his immediately preceding employer and his
benefits attributable to the company match under Tyco's 401(k) and supplemental
plans, adjusted to reflect earnings. At his current pay level, Mr. FitzPatrick
will have a

                                       42
<Page>
lifetime benefit of $34,794 per month, commencing at his normal retirement age
of 62. One-half of this amount will continue to his surviving spouse in the
event of his death. Retirement benefits are available at an earlier age but
would be reduced by .25% for each month that the benefit commences prior to age
62 and could result in a forfeiture of any unvested portion. Mr. FitzPatrick may
elect to receive the actuarial equivalent of his annuity in the form of a lump
sum payment.

    As part of his employment agreement, Mr. Lytton is provided with a
Supplemental Retirement Benefit. Commencing at age 62, Mr. Lytton will receive a
monthly annuity based upon 6.25% of his highest average earnings from Tyco
during any consecutive 36-month period within the 60-month period prior to his
termination multiplied by his years of service with Tyco. This monthly annuity
is offset by any benefits provided under a defined benefit plan maintained by
his immediately preceding employer and his benefits attributable to the company
match under Tyco's 401(k) and supplemental plans, adjusted to reflect earnings.
At his current pay level, Mr. Lytton will have a lifetime benefit of $48,779 per
month, commencing at his normal retirement age of 62. One-half of this amount
will continue to his surviving spouse in the event of his death. Retirement
benefits are available at an earlier age but would be reduced by .25% for each
month that the benefit commences prior to age 62 and could result in a
forfeiture of any unvested portion. Mr. Lytton may elect to receive the
actuarial equivalent of his annuity in the form of a lump sum payment.

    As part of his employment agreement, Mr. Pillmore is provided with a
Supplemental Retirement Benefit. Commencing at age 62, Mr. Pillmore will receive
a monthly annuity based upon 2% of his highest average earnings from Tyco during
any consecutive 36-month period within the 60-month period prior to his
termination multiplied by his years of service with Tyco. This monthly annuity
is offset by his benefits attributable to the company match under Tyco's 401(k)
and supplemental plans, adjusted to reflect earnings. At his current pay level,
Mr. Pillmore will have a lifetime benefit of $12,716 per month, commencing at
his normal retirement age of 62. Retirement benefits are available at an earlier
age but would be reduced by .25% for each month that the benefit commences prior
to age 62 and could result in a forfeiture of any unvested portion.
Mr. Pillmore may elect to receive the actuarial equivalent of his annuity in the
form of a lump sum payment.

    At the time of Tyco's acquisition of AMP in 1999, Dr. Gromer was a
participant in a defined benefit pension plan that covered eligible AMP
employees in Germany. As a result, Dr. Gromer is entitled to receive from Tyco
upon retirement at age 65 a defined pension benefit that is determined primarily
based on his annual base salary as of three years prior to the date of his
retirement and his years of service with Tyco at the time of his retirement. The
following table sets forth the estimated annual benefits payable under the Tyco
Electronics (formerly AMP) pension plan for the compensation amounts and the
years of credited service specified in the table, assuming benefits are paid in
the form of a single life annuity upon normal retirement at age 65:

CONVERTED FROM EUROS USING A CONVERSION RATIO OF $1.00 TO E0.9768.

    The compensation of Dr. Gromer covered by the pension plan would be the base
salary amount that is noted in the "Salary" column of the SUMMARY COMPENSATION
TABLE above, less statutory payments for specified holiday and vacation time.
Dr. Gromer's current covered compensation, designated in Euro is E700,584, which
converts to $717,223 using a conversion ratio of $1.00 to E0.9768. Under the
pension plan, no more than a maximum of 30 years of credited service may be
recognized for benefit accrual purposes. As of September 30, 2002, for purposes
of calculating benefits accrued under the pension plan, Dr. Gromer had 24 years
and 9 months of credited service with Tyco.

    Dr. Gromer is a beneficiary under another AMP pension benefit funded through
an insurance policy. At September 30, 2002, Dr. Gromer had accrued a taxable
pension of $3,849 per year payable at retirement through this insurance. This
amount is subject to increase in future periods only to the extent of dividends
on the insurance policy.

    Messrs. Kozlowski and Swartz participated in individual Executive Retirement
Arrangements maintained by Tyco (the "ERA"). Under the ERA, Mr. Kozlowski has a
fixed lifetime benefit commencing at his normal retirement age of 65 that has a
present value of $372,708 monthly. Mr. Swartz's fixed lifetime benefit at his
normal retirement age of 65 has a present value of $167,446 monthly. Retirement
benefits are available at earlier ages and alternative forms of benefits can be
elected. Any such variations would be actuarially equivalent to the fixed
lifetime benefit starting at age 65. We are seeking disgorgement of all benefits
to Messrs. Kozlowski and Swartz under their ERAs. See footnotes 15 and 16 to
SUMMARY COMPENSATION TABLE above.

FORMER EXECUTIVE LIFE INSURANCE

    Tyco purchased executive life insurance policies for Messrs. Kozlowski and
Swartz and agreed to pay premiums of a specified amount for these insurance
policies for an 11-year period beginning in fiscal 2001. In the event the
policies do not earn specified interest amounts, Tyco agreed to make specified
supplemental premium payments. The amounts paid for premiums in fiscal 2002 and
2001 are included under the caption ALL OTHER COMPENSATION in the SUMMARY
COMPENSATION TABLE above. In conjunction with Mr. Swartz's termination of
employment, a lump sum payment of $24,554,077.14, which represented the value of
the annual premium amounts for the remainder of the eleven-year period, was made
to Mr. Swartz and in return Mr. Swartz waived Tyco's obligation to continue
making the premium payments. Tyco discontinued making premium payments for
Mr. Kozlowski's insurance policy as of October 1, 2002. We are seeking
disgorgement of all benefits to Messrs. Kozlowski and Swartz under their
executive life insurance policies. See footnotes 15 and 16 to SUMMARY
COMPENSATION TABLE above.

supplemental retirement benefits and to offer him continued participation in our
health and welfare plans for a period of three years. In the event that

to the fullest extent permitted by law and under Tyco's bye-laws.

    Our employment agreement with Mr. Lytton is dated as of September 30, 2002

    Our employment agreement with Mr. Pillmore is dated as of August 12, 2002.
The agreement provides for Mr. Pillmore to serve as our Senior Vice President,

Mr. Pillmore is also entitled to participate in all of our employee benefit

benefits that he would have accrued assuming he had been credited with three
additional years of service and all of his outstanding equity awards will vest.
"Good reason" includes any termination by the executive during the 30-day period
immediately following the 15-month anniversary of the date of a change in
control or the breach of the following representation made by us if such breach
has a material adverse impact on Tyco. Tyco has represented in Mr. Pillmore's

    Tyco is party to a retention agreement with Richard J. Meelia, which is
filed as an exhibit to our Quarterly Report on Form 10-Q for the fiscal quarter
ended December 31, 2001. Under the agreement, if Mr. Meelia is terminated by us
without cause or upon disability or Mr. Meelia resigns for good reason

                                       47
<Page>
(each as defined in the agreement) prior to February 28, 2005, then he is
entitled to receive a lump sum payment equal to three times the sum of his
annual base salary, average cash bonus during the prior four fiscal years and
the greater of 10% of his base salary or $20,000, as well as a pro rata portion
of the maximum annual bonus that he would have been eligible for in the year of
termination. Mr. Meelia would also be entitled to receive certain welfare,
fringe, and other benefits comparable to those provided to him prior to
termination for a period of three years from his termination date. Additionally,
all options and restricted shares owned by Mr. Meelia and not already vested
would continue to vest for a period of three years from termination. Under the
agreement, if Mr. Meelia is terminated by us without cause or upon disability at
any time after February 28, 2005, Mr. Meelia may elect to receive the same
severance benefits if he agrees not to disparage or compete with us or to
solicit managerial level employees or customers of Tyco for a period of three
years following his termination. The payments provided for in the agreement are
subject to additional gross-up payments in the event that such payments are
subject to federal excise tax. All of Mr. Meelia's unvested options and
restricted shares vest in full immediately upon a change in control of Tyco (as
defined therein).

    On January 22, 2001, Tyco entered into a retention agreement with
Mr. Kozlowski. The agreement, as amended on August 1, 2001, was not properly
approved, but purported to provide for an award of 800,000 restricted shares to
be made on January, 22, 2002, with 1/8 of the common shares vesting each year
beginning in January 2002 and full vesting upon Mr. Kozlowski's 62nd birthday on
November 16, 2008. The agreement further provided that Mr. Kozlowski could sell
the restricted shares to Tyco once the common shares vest at the fair market
value on the date he elects to do so. The agreement provided that Mr. Kozlowski
could retire at any time after November 16, 2008, and, with the consent of
Tyco's Board, could retire before that date. If Mr. Kozlowski were terminated
for "cause" or voluntarily resigned without "good reason" (each as defined in
the retention agreement) prior to November 16, 2008, the agreement provided that
he would receive no retirement payments under the agreement and any remaining
common shares would not vest. However, if Mr. Kozlowski were terminated by the
Board without cause or left for good reason, the agreement provided that he
would receive a lump sum payment equal to three times the sum of his annual base
salary and highest annual incentive compensation earned within the prior eight
year period. Additionally, all options and restricted shares under the agreement
or any company program not already vested would become vested at that time. The
agreement also provided that he would receive payment for his services as a
consultant annually in the amount of 1/12 of the sum of his last annual base
salary and highest annual incentive compensation. The agreement provided that
Mr. Kozlowski would continue to receive welfare, fringe, and other benefits
comparable to those provided prior to retirement including, among other
benefits, access to company facilities and services, and would receive three
additional years of credits under the nonqualified retirement plan.
Mr. Kozlowski resigned on June 3, 2002. Tyco has taken the position that the
agreement is not valid or enforceable because of Mr. Kozlowski's fraudulent
misrepresentation, breach of fiduciary duty and other misconduct. In addition,
Tyco has brought an action against Mr. Kozlowski seeking disgorgement of all
compensation and forfeiture of all benefits to him under the retention
agreement. See footnote 15 to the SUMMARY COMPENSATION TABLE above.

    On January 22, 2001, Tyco entered into a retention agreement with
Mr. Swartz. The agreement, as amended on August 1, 2001, was not properly
approved, but purported to provide for an award of 500,000 restricted shares to
be made on January, 22, 2002, with full vesting of the common shares on
January 22, 2006. The agreement further provided that Mr. Swartz could sell the
restricted shares to Tyco once the common shares vest at their fair market value
on the date he elects to do so. If Mr. Swartz were terminated for "cause" or
voluntarily resigned without "good reason" (each as defined in the retention
agreement) prior to January 22, 2006, the agreement provided that he would
receive no retirement payments under the agreement and any remaining common
shares would not vest. However, if Swartz were terminated by the Board without
cause or left for good reason, the agreement provided that he would receive a
lump sum payment equal to three times the sum of his annual base salary and
highest annual incentive compensation earned within the prior six year period.
Additionally, all options and restricted shares under the agreement or any
company program not already vested would become vested at that time. The
agreement also

                                       48
<Page>
provided that he would receive payment for his services as a consultant annually
for a period of three years in the amount of 1/12 of the sum of his last annual
base salary and highest annual incentive compensation. The agreement provided
that Mr. Swartz would continue to receive welfare, fringe, and other benefits
comparable to those provided prior to retirement including, among other
benefits, access to company facilities and services, and would receive three
additional years of credits under the nonqualified retirement plan. Mr. Swartz
resigned in August 2002.

    On August 1, 2002, Tyco entered into a severance agreement with Mr. Swartz
which provided that Mr. Swartz would waive his rights under the August 1, 2001
amendment to his retention agreement and that Tyco would treat Mr. Swartz's
leaving Tyco as if it were a resignation for good reason. The severance
agreement provided that Tyco would pay Mr. Swartz amounts due Mr. Swartz under
Tyco's Deferred Compensation Plan, the current value of Mr. Swartz's Executive
Life Insurance Program, amounts due to Mr. Swartz under his 401(k) plan and
amounts due to Mr. Swartz under his Supplemental Executive Retirement Program.
In connection with the severance agreement, Mr. Swartz retained his claim to any
amounts owned to him under his Executive Retirement Agreement. The agreement
also provided that all disputes between Tyco and Mr. Swartz arising from or
concerning his employment at Tyco would be subject to binding arbitration. Tyco
has filed an arbitration claim against Mr. Swartz seeking disgorgement of all
compensation and forfeiture of all benefits to him under the retention agreement
and severance agreement. See footnote 16 to the SUMMARY COMPENSATION TABLE
above.

RELATED PARTY TRANSACTIONS

    Tyco has amounts due related to loans and advances issued to employees under
Tyco's Key Employee Loan Program, relocation programs and other advances made to
executives. Loans were provided to employees under Tyco's Key Employee Loan
Program for the payment of taxes upon the vesting of common shares granted under
our restricted share ownership plans. The loans are unsecured and bear interest,
payable annually, at a rate based on the six month LIBOR rate, calculated
annually as the average of the 12 rates in effect on the first day of the month.
Loans are generally repayable in ten years, except that earlier payments are
required under certain circumstances. In addition, Tyco made loans secured by
mortgages to certain employees under employee relocation programs. These loans
are generally payable in 15 years and are secured by the underlying property.
During fiscal 2002, the maximum amount outstanding under these programs was
$117.5 million. Loans receivable under these programs, as well as other
unsecured advances outstanding, were $88.1 and $93.4 million at September 30,
2002 and 2001, respectively. Certain of the above loans totaling $30.3 million
and $33.7 million at September 30, 2002 and 2001, respectively, are non-interest
bearing. Interest income on interest bearing loans totaled $5.5 million,
$1.3 million, and $3.7 million in fiscal 2002, fiscal 2001 and fiscal 2000,
respectively.

    During fiscal 2002, Mr. Kozlowski had outstanding loans from Tyco. The rate
of interest charged on such loans was 1.91%. The maximum amount outstanding
under these loans during fiscal 2002 was $51.0 million plus accrued interest of
$3.2 million, and the amount outstanding at September 30, 2002 was
$47.0 million. During fiscal 2001 and 2000, Mr. Kozlowski had outstanding loans
from Tyco under our Key Employee Loan Program. The maximum amount of such loans
previously reported in each of fiscal 2001 and 2000 were understated by
approximately $25 million, plus accrued interest at the time. In addition,
during fiscal 2001 and fiscal 2000, Mr. Kozlowski received $9,719,696 and
$19,439,392 in unauthorized mortgage loans that were later forgiven without
proper approval. Mr. Kozlowski also received an unauthorized gross-up payment to
cover taxes payable due to income associated with such forgiveness. See footnote
21 to the SUMMARY COMPENSATION TABLE set forth in the caption entitled
"Executive Compensation" above.

    During fiscal 2002, Mr. Swartz had outstanding loans from Tyco. The rate of
interest charged on such loans was 2.11%. The maximum amount outstanding under

$14.8 million, $14.5 million is a non-interest bearing mortgage loan and
$0.3 million is in the form of an interest bearing promissory note. The interest
rate on the promissory note was 2.78% for fiscal 2002. We have filed a civil
complaint against Mr. Belnick for breach of fiduciary duty and other wrongful
conduct. More information with respect to this action was reported on

management team adopted a policy under which no new loans are allowed to be
granted to any officers of Tyco and existing loans are not allowed to be
extended or modified.

    Certain Tyco directors and executive officers owned TyCom Ltd. common shares
or options, which were converted to Tyco common shares and Tyco options upon the
amalgamation of a subsidiary of Tyco with TyCom Ltd. on December 18, 2001 at the
exchange ratio applicable to all holders of TyCom Ltd. common shares and
options.

    Joshua M. Berman was a director of Tyco until December 5, 2002. From
March 1, 2000 through July 31, 2002, Tyco also engaged Mr. Berman to render
legal and other services. During this period, Tyco compensated Mr. Berman at an
annual rate of $360,000 and provided Mr. Berman with health benefits,
secretarial assistance, a cell phone and electronic security services for his
homes. Tyco also reimbursed Mr. Berman for legal fees and expenses incurred by
him in connection with matters relating to Tyco pursuant to indemnification
provisions applicable to all directors of Tyco. Mr. Berman is a retired counsel
to the law firm Kramer Levin Naftalis & Frankel LLP, which provided legal
services to us in fiscal 2002.

MicroWarehouse approximately $1.5 million for products in 2002.

    As previously reported in our Quarterly Report on Form 10-Q for the fiscal
quarter ended June 30, 2002, and our Annual Report on Form 10-K for the fiscal
period ended September 30, 2002, Tyco and certain of our current and former
directors are defendants in four pending actions purporting to bring suit
derivatively on behalf of Tyco against certain former officers and certain
current and former directors of

                                       50
<Page>
Tyco and against Tyco as a nominal defendant in connection with alleged improper
conduct of former officers of Tyco relating to the use of our funds, our Key
Employee Loan Program and assets. The ultimate resolution of these actions is
not yet determinable.

    As previously reported on September 17, 2002 and October 8, 2002 in our
Current Reports on Form 8-K, Tyco has filed civil complaints against
Mr. Kozlowski and Mr. Belnick, and an arbitration claim against Mr. Swartz, for
breach of fiduciary duty and other wrongful conduct relating to alleged abuses
of our Key Employee Loan Program and relocation program, unauthorized bonuses,
unauthorized payments, self-dealing transactions or other improper conduct.

    As previously reported on September 17, 2002 in our Current Report on
Form 8-K, on June 17, 2002, Tyco filed a civil complaint against our former
director Frank E. Walsh, Jr. for breach of fiduciary duty, inducing breaches of
fiduciary duty and related wrongful conduct involving a $20 million payment by
Tyco, $10 million of which went to Mr. Walsh with the balance going to a charity
of which Mr. Walsh is trustee. The payment was purportedly made for Mr. Walsh's
assistance in arranging our acquisition of The CIT Group, Inc. On December 17,
2002, Mr. Walsh pleaded guilty to a felony violation of New York law in the
Supreme Court of the State of New York, (New York County) and settled a civil
action for violation of federal securities laws brought by the Securities and
Exchange Commission in United States District Court for the Southern District of
New York. Both the felony charge and the civil action were brought against
Mr. Walsh based on such payment. The felony charge accused Mr. Walsh of
intentionally concealing information concerning the payment from Tyco's
directors and shareholders while engaged in the sale of Tyco securities in the
State of New York. The SEC action alleged that Mr. Walsh knew that the
registration statement covering the sale of Tyco securities as part of the CIT
acquisition contained a material misrepresentation concerning fees payable in
connection with the acquisition. Pursuant to the plea and settlement, Mr. Walsh
paid $20 million in restitution to Tyco on December 17, 2002. Our claims against
Mr. Walsh are still pending.

    Tyco has filed a civil complaint against Messrs. Kozlowski and Swartz
pursuant to Section 16(b) of the Securities Exchange Act of 1934 for
disgorgement to Tyco of short-swing profits from transactions in our common
shares believed to exceed $40 million. The action seeks disgorgement of profits,
interest, attorneys' fees and costs.

                                 OTHER MATTERS

COSTS OF SOLICITATION

    The cost of solicitation of proxies will be paid by Tyco. Tyco has engaged
MacKenzie Partners, Inc. as the proxy solicitor for the Annual General Meeting
for an approximate fee of $9,500. In addition to the use of the mails, certain
directors, officers or employees of Tyco may solicit proxies by telephone or
personal contact. Upon request, Tyco will reimburse brokers, dealers, banks and
trustees, or their nominees, for reasonable expenses incurred by them in
forwarding proxy materials to beneficial owners of common shares.

SECTION 16(A) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

    Section 16(a) of the Securities Exchange Act of 1934 requires Tyco's
officers and directors and persons who beneficially own more than ten percent of
Tyco's common shares to file reports of ownership and changes in ownership of
such common shares with the SEC and the New York Stock Exchange. These persons
are required by SEC regulations to furnish Tyco with copies of all
Section 16(a) forms they file. As a matter of practice, Tyco's administrative
staff assists Tyco's officers and directors in preparing initial reports of
ownership and reports of changes in ownership and files those reports on their
behalf. Based solely on Tyco's review of the copies of such forms it has
received and written representations from certain reporting persons confirming
that they were not required to file Forms 5 for specified fiscal years, Tyco
believes that all of its officers, directors and beneficial owners of more than
ten percent of its common shares complied with Section 16(a) during Tyco's
fiscal year ended September 30, 2002, except for (i) Mr. Fort who reported one
transaction six months late, (ii) Mr. Welch who reported one transaction eight
months late and another transaction seven months late, (iii) Mr. Breen who
reported his initial statement of beneficial ownership on Form 3 four days late,
(iv) Mr. FitzPatrick who reported his initial statement of beneficial ownership
on Form 3 14 days late and one transaction 20 days late, (v) Mr. Lytton who
reported four transactions eight days late (these transactions occurred on the
same day), (vi) Mr. Kozlowski who failed to report approximately 12 transactions
and (vii) Mr. Swartz who failed to report approximately 14 transactions.
