                   [GENERAL SURGICAL INNOVATIONS, INC. LOGO]

                                                                October   , 1999

Dear GSI Shareholder:

    You are cordially invited to attend a Special Meeting of Shareholders of
General Surgical Innovations, Inc. which will be held on October   , 1999, at
10:00 a.m., Pacific Time, at GSI's principal executive offices located at 10460
Bubb Road, Cupertino, California 95014.

    At the meeting, you will be asked to approve and adopt an Agreement and Plan
of Merger that GSI has entered into with subsidiaries of Tyco International Ltd.
The merger agreement provides for the merger of GSI with a Tyco subsidiary, as a
result of which GSI will become an indirect wholly owned Tyco subsidiary and GSI
shareholders will become Tyco shareholders. Tyco has guaranteed the obligations
of its subsidiaries in the merger.

    If this merger is approved, you will receive a fraction of a Tyco common
share for each share of GSI common stock valued at $7.50. This fraction is
determined by the average of the daily volume weighted selling prices of Tyco
common shares on the New York Stock Exchange over the five trading days ending
four trading days before the GSI shareholders meeting.

    Tyco common shares are listed on the New York Stock Exchange and the Bermuda
Stock Exchange under the symbol "TYC" and on the London Stock Exchange under the
symbol "TYI."

    The accompanying Proxy Statement/Prospectus provides a detailed description
of the proposed merger and the merger consideration, as well as the effects of
the merger on you as a shareholder and on GSI. I urge you to read the enclosed
materials carefully.

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

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

                                          Sincerely,

                                          Gregory D. Casciaro
                                          PRESIDENT AND CHIEF EXECUTIVE OFFICER

      SEE "RISK FACTORS" BEGINNING ON PAGE   FOR A DISCUSSION OF ISSUES WHICH
  SHOULD BE CONSIDERED BY SHAREHOLDERS WITH RESPECT TO THE MERGER.

      Neither the Securities and Exchange Commission nor any state securities
  commission has approved or disapproved the Tyco common shares to be issued
  in the merger or determined if this Proxy Statement/Prospectus is truthful
  or complete. Any representation to the contrary is a criminal offense.

    Proxy Statement/Prospectus dated October   , 1999 and first mailed to
shareholders on or about October   , 1999.

                QUESTIONS AND ANSWERS ABOUT THE TYCO/GSI MERGER

    Q. WHY ARE TYCO AND GSI PROPOSING THE MERGER?

    A.  GSI's line of balloon dissectors and related devices for minimally
invasive surgery are complementary to related products manufactured and marketed
by Tyco's healthcare products group. With the greater resources available to
Tyco, the merger should provide a means to significantly enhance the development
and distribution of GSI's products. The merger will also give GSI shareholders
the opportunity to participate in a substantially larger and more diversified
public company.

    Based on current market prices for Tyco common shares, all GSI shareholders
will receive a significant premium for their shares over the value of the GSI
common stock on August 20, 1999, the last trading day before the merger was
publicly announced.

    Q. WHAT WILL I RECEIVE IN THE MERGER?

    A.  You will receive a fraction of a Tyco common share for each of your
shares of GSI common stock. This fraction is referred to as the "exchange
ratio." The exchange ratio is designed so that GSI shareholders will receive
$7.50 worth of Tyco common shares for each of their shares of GSI common stock
based upon the "average share price" for Tyco common shares. The average share
price will be computed by taking the average of the daily volume weighted
selling prices of Tyco common shares on the New York Stock Exchange over the
five trading days ending four trading days before the special meeting of GSI
shareholders. Cash will be paid instead of the distribution of fractional
shares.

    Q. HOW WILL I KNOW WHAT THE EXCHANGE RATIO IS?

    A.  You can call toll free 1-   -   -    at any time beginning on October
  , 1999, after the close of trading, for a voice recording with the exchange
ratio. If the average share price is less than $82.15, you will be informed that
General Acquisition has the right to call off the merger unless GSI agrees to an
exchange ratio of 0.0913 and will be advised to call again on October   , 1999
for final information on the exchange ratio. These numbers are not adjusted for
a two-for-one stock split of Tyco common shares payable on October 21, 1999.

    Q. WHAT SHOULD I DO NOW?

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

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

    You should not send in your share certificates now. After the merger is
completed, you will be sent written instructions for exchanging your share
certificates.

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

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

    Q. WHEN WILL THE MERGER TAKE EFFECT?

    A.  The merger is expected to take effect on the date GSI shareholders
approve and adopt the merger agreement at a special meeting of shareholders.

    Q. IF MY SHARES OF GSI COMMON STOCK ARE HELD BY A BANK OR BROKER, HOW CAN I
VOTE?

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

    Q. WHAT SHOULD I DO IF I HAVE QUESTIONS?

    A.  You should call         at 1-   -   -     (toll free in the United
States) or 1-   -    -    (call collect).

GENERAL SURGICAL INNOVATIONS, INC.
10460 Bubb Road
Cupertino, California 95014
(408) 863-1100

    Since its inception in April 1992, GSI has been engaged in the development,
manufacturing and marketing of balloon dissection systems and related minimally
invasive surgical instruments. GSI began commercial sales of its balloon
dissection systems for hernia repair in September 1993. To date, GSI has
received from the FDA eight 510(k) clearances for use of its technology to
perform dissection of tissue planes anywhere in the body using a broad range of
balloon sizes and shapes. GSI currently sells products in the United States,
Europe, South America and Australia for selected applications, such as hernia
repair, subfascial endoscopic perforator surgery, saphenous vein harvesting,
breast reconstruction and augmentation surgery, and laparoscopic bladder neck
suspension.

    Sales of GSI's products in the United States and internationally are
currently made through both distributors and GSI's direct sales force. To date,
the majority of the sales of GSI's products have been for use in hernia repair
procedures. While GSI had developed or is developing surgical balloon dissectors
for stress urinary incontinence and vascular and plastic surgery, sales of
products for hernia repair are expected to provide a majority of GSI's revenues
at least through fiscal year 2000.

                         THE SPECIAL MEETING (PAGE   )

    The special meeting of GSI shareholders will be held on October   , 1999, at
10:00 a.m., Pacific Time, at 10460 Bubb Road, Cupertino, California 95014.

    The record date for GSI shareholders entitled to receive notice of and to
vote at the GSI special meeting is the close of business on October   , 1999. On
that date, there were             shares of GSI common stock outstanding.

                              THE MERGER (PAGE   )

    SHAREHOLDER VOTE REQUIRED

    The holders of a majority of the outstanding shares of GSI common stock must
vote for the approval and adoption of the merger agreement in order to approve
the merger.

    DISSENTERS' RIGHTS

    Under California law, any shareholder who does not wish to accept the
consideration provided for in the merger agreement is entitled to exercise
dissenters' rights. Such rights entitle the shareholder to require GSI to
purchase the dissenting shares for cash at their fair market value, excluding
any element of value arising from the accomplishment or expectation of the
merger.

    Annex C contains the pertinent provisions of California law addressing
dissenters' rights. Any GSI shareholder intending to exercise statutory
dissenter's rights is urged to review Annex C carefully and to consult with
legal counsel so as to assure strict compliance with its provisions.

    A vote in favor of the merger agreement and the merger will constitute a
waiver of your dissenters' right. For further information regarding dissenters'
rights, see "The Merger-- Dissenters' Rights."

    TAX TREATMENT

    The receipt of Tyco common shares in the merger will generally be tax free
to GSI shareholders for United States federal income tax purposes, except for
tax on cash received in lieu of fractional shares.

    To review tax consequences of the merger in greater detail, see "Material
U.S. Federal Income Tax and Bermuda Tax Consequences" beginning on page   .

    INTERESTS OF OFFICERS AND DIRECTORS IN THE MERGER

    In considering the recommendation of the GSI Board in favor of the merger,
shareholders should be aware that members of the GSI Board and GSI management
will receive benefits as a result of the merger that will be in addition to or
different from benefits received by GSI shareholders generally. For example,
options to purchase shares of GSI common stock that are held by GSI's directors
and members of its management generally will become fully vested and exercisable
prior to the consummation of the merger. In addition, under certain qualifying
circumstances, members of GSI management will be entitled to receive severance
benefits upon actual or constructive termination of their employment following
the merger. Also, certain members of GSI management are eligible to receive
retention bonuses if they do not terminate their employment with GSI prior to
consummation of the merger. See "Interests of Certain Persons in the Merger"
beginning on page   .

    CONDITIONS OF THE MERGER

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

    - approval and adoption of the merger agreement by the GSI shareholders;

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

    - receipt of opinions regarding the tax-free nature of the merger in respect
      of the Tyco common shares received.

                                       3
<PAGE>
    TERMINATION OF THE MERGER

    Either GSI or General Acquisition may call off the merger if:

    - both parties consent in writing;

    - the merger is not completed by February 28, 2000 through no fault of the
      party seeking to call off the merger;

    - there exist legal restraints preventing the merger;

    - the GSI shareholders do not approve and adopt the merger agreement; or

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

    General Acquisition may terminate the merger if the average share price is
less than $82.15 (pre-split) and GSI does not agree to an exchange ratio equal
to 0.0913 (pre-split).

    In addition, General Acquisition may terminate the merger if the Board of
Directors of GSI withdraws or adversely modifies its approval or recommendation
of the merger or recommends an alternative acquisition transaction with a third
party. Subject to certain conditions, GSI may terminate the merger to accept an
acquisition proposal that is more favorable to GSI and its shareholders than the
proposed merger with General Acquisition.

    For further details, see "Termination" beginning on page   .

    NO-SOLICITATION PROVISIONS; TERMINATION FEE AND EXPENSES

    GSI has agreed that it will not solicit or encourage the initiation of any
inquiries or proposals regarding any alternative acquisition transactions with
third parties. GSI may respond to unsolicited transaction proposals if required
by the GSI Board's fiduciary duties. GSI must promptly notify Tyco if it
receives proposals for any such alternative acquisition transactions. If the
merger is terminated under specified circumstances, generally involving an
alternative acquisition transaction, GSI may be required to pay a termination
fee of $4.0 million to Tyco and pay reasonable out-of-pocket expenses of up to
$375,000 to Tyco and General Acquisition. General Acquisition may be required to
pay to GSI up to $375,000 of GSI's reasonable out-of-pocket expenses if the
merger is terminated under certain circumstances.

    See "Termination--Fees and Expenses" beginning on page   for a discussion of
the circumstances in which the fee and expenses are payable.

    In addition, GSI may not redeem or amend its rights plan to permit or
facilitate an alternative acquisition transaction unless the merger agreement
has been terminated. See "No Solicitation" beginning on page   .

    The termination fee and the no-solicitation provisions may have the effect
of discouraging persons who might be interested in entering into an acquisition
transaction with GSI from proposing an alternative acquisition transaction.

    ACCOUNTING TREATMENT

    The merger will be accounted for as a purchase by Tyco in accordance with
United States generally accepted accounting principles.

    OPINION OF GSI'S FINANCIAL ADVISOR

    In determining that the merger is fair to and in the best interests of GSI
and its shareholders, the GSI Board considered an opinion from its financial
advisor, ING Barings LLC, that, as of the date of such opinion, the
consideration to be received by the equity holders of GSI pursuant to the merger
agreement is fair from a financial point of view to such holders. See "Opinion
of Financial Advisor to GSI" on page   . The full text of the written opinion of
ING Barings is attached as Annex B. YOU SHOULD READ THIS OPINION.

<PAGE>
                                  RISK FACTORS

    In evaluating the merger and the merger agreement, GSI shareholders should
take into account the following factors:

    THE VALUE OF THE MERGER CONSIDERATION THE GSI SHAREHOLDERS WILL RECEIVE WILL
DEPEND ON THE VALUE OF TYCO COMMON SHARES AT THE TIME OF THE MERGER.

    Although the merger is designed to provide GSI shareholders with
approximately $7.50 worth of Tyco common shares for each share of GSI common
stock, they could get less in market value. The merger values the Tyco common
shares that GSI shareholders will receive based upon the "average share price."
The average share price is computed by taking the average of the daily volume
weighted selling prices of Tyco common shares on the New York Stock Exchange
over the five trading days ending four trading days before the special meeting
of GSI shareholders. At the time of the merger, which is expected but not
certain to occur promptly following the meeting, the market price of a Tyco
common share could be more or less than the average share price used in
calculating the exchange ratio. If it is less, the value of the Tyco common
shares that a GSI shareholder receives in the merger could be less than $7.50.
The market value of Tyco shares fluctuates based upon general market and
economic conditions, Tyco's business and prospects and other factors.

    GSI shareholders should also note that they will receive less than $7.50
worth of Tyco common shares, calculated on the basis of the average share price,
if the average share price is less than $82.15 (pre-split) and GSI agrees to an
exchange ratio of 0.0913 (pre-split) so that General Acquisition will not have
the right to call off the merger.

    THE RIGHTS OF SHAREHOLDERS OF TYCO UNDER BERMUDA LAW IN SOME WAYS ARE NOT AS
FAVORABLE AS THE RIGHTS OF SHAREHOLDERS OF GSI UNDER CALIFORNIA LAW.

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

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

    - Under Bermuda law and Tyco's bye-laws, only shareholders holding 5% or
      more of the outstanding Tyco shares or numbering 100 or more are entitled
      to propose a resolution at a Tyco general meeting. The Tyco Board can
      waive these requirements, and the staff of the SEC has taken the position
      that the United States proxy rules may require Tyco to include in its
      proxy materials proposals of shareholders who do not satisfy the
      requirements. GSI shareholders do not have to satisfy these requirements
      to propose a resolution at a GSI shareholders meeting.

    - the ability to achieve anticipated synergies and other cost savings in
      connection with acquisitions,

    - the timing, impact and other uncertainties of future acquisitions by Tyco,
      and

    Report on Form 10-Q for the quarterly period ended June 30, 1999, which is
    incorporated by reference in this document.

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

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

(4) On July 2, 1997, Tyco, formerly called ADT Limited, merged with Tyco
    International Ltd., a Massachusetts Corporation ("Former Tyco"). On August
    27, 1997, August 29, 1997, October 1, 1998 and April 2, 1999, Tyco merged
    with INBRAND Corporation, Keystone International, Inc., US Surgical and AMP,
    respectively. These five combinations are more fully described in Notes 1
    and 2 to the Consolidated Financial Statements contained in Tyco's Current
    Report on Form 8-K filed on June 3, 1999. Operating income in the nine
    months ended September 30, 1997 includes charges related to merger,
    restructuring and other non-recurring costs of $917.8 million and

                                       8
<PAGE>
    impairment of long-lived assets of $148.4 million primiarily related to the
    mergers and integration of ADT, Former Tyco, Keystone and INBRAND and
    charges of $24.3 million for litigation and other related costs and $5.8
    million for restructuring charges in US Surgical's operations. See Notes 11
    and 16 to the Consolidated Financial Statements contained in Tyco's Current
    Report on Form 8-K filed on June 3, 1999. The results for the nine months
    ended September 30, 1997 also include a charge of $361.0 million for the
    write-off of purchased in-process research and development related to the
    acquisition of the submarine systems business of AT&T Corp.

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

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

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

(8) Per share amounts have been retroactively restated to give effect to the
    mergers with Former Tyco, Keystone, INBRAND, US Surgical and AMP, a 0.48133
    reverse stock split effected on July 2, 1997, and a two-for-one stock split
    distributed on October 22, 1997, effected in the form of a stock dividend.
    Per share amounts have not been retroactively adjusted to reflect the
    two-for-one stock split payable on October 21, 1999 in the form of a stock
    dividend.

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

(1) Tyco has a September 30 fiscal year end. GSI has a June 30 fiscal year end.
    For purposes of the unaudited pro forma combined statements of operations
    data, operating results for the nine months ended June 30, 1999 have been
    combined using the results of Tyco and GSI for such period, and the
    operating results for the fiscal year ended September 30, 1998 have been
    combined using the results of Tyco for the fiscal year ended September 30,
    1998 and results of GSI for its fiscal year ended June 30, 1998. For
    purposes of the unaudited pro forma combined balance sheet data, the
    financial position at June 30, 1999 combines the balance sheets of Tyco and
    GSI as of such date.

(2) See Notes (1) and (2) to "Selected Consolidated Historical Financial Data of
    Tyco" on page 8 for information on certain non-recurring items.

(3) The unaudited pro forma combined per share data are based on GSI
    shareholders receiving 0.0734 of a Tyco common share for each share of GSI
    common stock held, which assumes an average share price for Tyco common
    shares of $102.1875. The actual average share price may be higher or lower
    than this value. For purposes of the unaudited pro forma combined financial
    information, the number of GSI common shares outstanding on August 20, 1999
    of 13,838,181 was used. The per share data have not been retroactively
    adjusted to reflect the two-for-one Tyco stock split payable on October 21,
    1999.

(4) Tyco has paid a quarterly dividend of $0.025 per common share since July 2,
    1997, the date of the Former Tyco/ADT Merger. GSI has paid no dividends
    since its inception in April 1992.

                          CURRENT DEVELOPMENTS OF TYCO

    In July 1999, Tyco announced that its Board of Directors had declared a
two-for-one stock split on its common shares. The split will be in the form of a
100 percent stock distribution payable on October 21, 1999 to shareholders of
record on October 1, 1999. Per share amounts and share data within this document
have not been retroactively adjusted to reflect the stock split.

    In August 1999, a subsidiary of Tyco consummated the private sale of $500
million aggregate principal amount of its floating rate notes due 2000, $500
million aggregate principal amount of its floating rate notes due 2001, $1
billion aggregate principal amount of 6 7/8% notes due 2002 and Y10 billion
(approximately $89.7 million) aggregate principal amount of 0.57% notes due
2000. The net proceeds of approximately $2.08 billion were used to repay a
portion of the borrowings under the $3.90 billion commercial paper program of
the issuing subsidiary.

    On August 12, 1999, Tyco consummated its acquisition of Raychem Corporation.
In the transaction, a subsidiary of Tyco paid approximately $1.45 billion in
cash and delivered approximately 16.2 million Tyco common shares and assumed
approximately $590 million of Raychem debt. Raychem, with fiscal 1998 revenues
of $1.8 billion, is a leading international designer, manufacturer and
distributor of high-performance electronics products for OEM businesses, and for
a broad range of specialized telecommunications, energy and industrial
applications, and will be integrated within Tyco's Telecommunications and
Electronics group (formerly the Electrical and Electronic Components group).
Tyco has accounted for the acquisition as a purchase.

    On August 17, 1999, Tyco announced the completion of the sale of certain
businesses within its flow control products division, including The Mueller
Company and Grinnell Supply Sales and Manufacturing, for approximately $810
million in cash.

    On August 31, 1999, Tyco announced that a subsidiary of Tyco entered into a
definitive agreement to acquire AFC Cable Systems, Inc., a manufacturer of
prewired armor cable. AFC Cable shareholders will receive a fraction of a Tyco
share valued at $45.00 per share for each share of AFC Cable. The transaction is
valued at approximately $575 million and is contingent upon customary regulatory
review and approval by AFC Cable shareholders. AFC Cable will be integrated
within Tyco's Telecommunications and Electronics group. Tyco intends to account
for the acquisition as a purchase.

    In September 1999, Tyco's Board of Directors amended its shareholder rights
plan to accelerate the plan's expiration date to September 30, 1999. The plan
will terminate on that date.

               GENERAL SURGICAL INNOVATIONS, INC. SPECIAL MEETING

DATE, TIME AND PLACE

    The special meeting of GSI shareholders will be held on October   , 1999, at
10:00 a.m., Pacific Time, at GSI's principal executive offices located at 10460
Bubb Road, Cupertino, California 95014.

PURPOSE OF THE GSI SPECIAL MEETING

    At the special meeting, GSI shareholders will consider and vote upon a
proposal to approve and adopt the Agreement and Plan of Merger, dated as of
August 23, 1999, among GSI, General Acquisition and General Sub. The merger
agreement provides, among other things, that General Sub will be merged with and
into GSI, and each outstanding share of GSI common stock will be converted into
the right to receive a fraction of a Tyco common share. General Acquisition and
General Sub are subsidiaries of Tyco, whose obligations in connection with the
merger are guaranteed by Tyco.

    GSI is not proposing any matters other than the approval and adoption of the
merger agreement to come before the GSI special meeting, and GSI has not
received notice of other proposals to be considered at the meeting.

RECORD DATE; VOTING RIGHTS; QUORUM; REQUIRED VOTE

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

    GSI has only one class of capital stock outstanding, which is common stock,
par value $0.001 per share. Each holder of GSI common stock outstanding on the
record date is entitled to one vote for each share held. The holders of a
majority of the outstanding shares of GSI common stock entitled to vote must be
present at the special meeting, in person or by proxy, to constitute a quorum to
transact business.

    The holders of a majority of the outstanding shares of GSI common stock must
vote for the approval and adoption of the merger agreement to approve the
merger. On the record date,             shares of GSI common stock were
outstanding, excluding shares held in treasury, held by approximately
            holders of record.

    Votes cast by proxy or in person at the GSI special meeting will be
tabulated by the election inspectors appointed for the meeting and will
determine whether or not a quorum is present. Abstentions will be treated as
shares present in determining whether GSI has a quorum for the special meeting,
but abstentions will have the same effect as a vote against approval of the
merger. If a broker or other record holder or nominee indicates on a proxy that
it does not have direction or authority to vote certain shares, those shares
will be considered present at the special meeting for purposes of determining a
quorum but will have the same effect as a vote against approval of the merger.

RECOMMENDATION OF THE BOARD OF DIRECTORS OF GSI

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

special meeting as instructed on those proxies. A shareholder who executes and
returns a proxy may revoke it at any time before it is voted, but only by
executing and returning a proxy bearing a later date, by giving written notice
of revocation to an officer of GSI, or by attending the special meeting and
voting in person. A proxy that has been properly executed, but has otherwise
been left blank, will be voted for the approval and adoption of the merger
agreement, unless the proxy is revoked before the vote is taken.

SOLICITATION OF PROXIES

                                   THE MERGER

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

BACKGROUND OF THE MERGER

    On various occasions between January and June 1999, the management of GSI,
including its president, Gregory Casciaro, and personnel from Tyco's United
States Surgical Corporation subsidiary conducted discussions concerning possible
strategic alliances between GSI and US Surgical. In these discussions, conducted
in phone conversations, at professional conferences and in June 1999 at GSI's
offices, the representatives of the parties explored possible distribution
arrangements, whereby US Surgical would be a distributor of GSI products or vice
versa. The representatives also raised the possibility of an acquisition of GSI
by Tyco.

    In February 1999, a jury entered a judgment in a patent infringement case
against Origin Medsystems, Inc., a unit of Guidant Corporation which was
acquired by US Surgical in July 1999. In April 1999, the court entered judgment
on the verdict, awarding GSI damages of $12.9 million and imposing a permanent
injunction against sales of Origin's infringing products to take effect
generally on November 15, 1999. Under the terms of US Surgical's purchase of
Origin, Guidant agreed to be responsible for the damage award. Origin's appeal
of the judgment, together with GSI's cross-appeal on certain issues, is pending.

    In June 1999, US Surgical began to conduct a valuation of GSI with a view
towards a possible acquisition proposal. On June 21, 1999, GSI retained ING
Barings LLC to assist GSI in evaluating its strategic alternatives.

    Beginning in July 1999, representatives of US Surgical and GSI's management
engaged in discussions regarding diligence and valuation issues. On July 28,
1999, US Surgical personnel and officers of Tyco International (US) Inc. met at
the offices of the Venture Law Group, GSI's outside counsel, with Mr. Casciaro
and other members of GSI's management and a representative of ING Barings to
discuss the businesses of GSI and Tyco, the valuation of GSI and diligence
activities in contemplation of a possible acquisition transaction.

    On August 2, 1999, a team from US Surgical reviewed diligence materials
assembled at the offices of GSI's outside counsel. Mr. Casciaro, other members
of GSI's management and GSI's outside counsel were also in attendance. On August
3, 1999, officers of Tyco (US) contacted Mr. Casciaro with a verbal offer of
$7.25 per share of GSI common stock payable in Tyco common shares. Mr. Casciaro
agreed to present this offer to the GSI Board, although he expressed
disappointment with the price. Thereafter, the Tyco (US) representatives
contacted ING Barings and raised Tyco's offer to $7.50 per share of GSI common
stock.

    GSI held a telephonic board meeting on August 5, 1999. At that meeting, ING
Barings and management of GSI presented the Tyco proposal to the Board. ING
Barings informed the GSI Board that Tyco's verbal offer had increased to $7.50
per GSI share. Following an extended discussion, the GSI Board authorized the
GSI management team and ING Barings to continue their discussions regarding a
transaction with Tyco at the $7.50 per share price.

                                       17
<PAGE>
    On August 6, 1999, GSI and Tyco (US) signed a letter of intent in which GSI
granted Tyco a right of exclusive negotiation for a specified time period. At a
meeting of the Tyco Board of Directors on August 9, 1999, the Tyco Board
approved the acquisition of GSI by General Acquisition in a merger transaction
at a price of $7.50 per share of GSI common stock and authorized the issuance of
Tyco common shares required to be delivered to GSI shareholders in the merger.

    Between August 6 and August 20, 1999, the parties and their advisors
negotiated the terms of definitive transaction documents and substantially
completed their respective due diligence reviews.

    On August 19, 1999, the GSI Board of Directors met with GSI management and
GSI's financial and legal advisors at a special meeting of the Board to review
the status of the negotiations with Tyco and the terms of the negotiated
transaction documents. After management provided its view of the proposed
merger, ING Barings presented its oral opinion, subsequently confirmed in
writing, that the consideration to be received by the shareholders of GSI in the
merger was fair, from a financial point of view, to the GSI shareholders. ING
Barings also provided the GSI Board with the financial analysis serving as a
basis for its opinion and responded to questions raised by the GSI Board
regarding the analysis and the opinion. Following this discussion, GSI's outside
counsel reviewed with the GSI Board the proposed terms of the merger agreement
and related documents. The GSI Board then engaged in a full discussion of the
terms of the proposed merger, including the strategic benefits of the
combination, the terms and conditions of the proposed merger agreement and the
analysis and opinion of ING Barings. The GSI Board concluded that the proposed
merger and merger agreement were fair to and in the best interests of GSI and
its shareholders. The GSI Board then approved the merger and the merger
agreement and the related documents and authorized management to proceed with
the final negotiation and execution of the merger documents.

    The boards of directors of General Acquisition and General Sub approved the
merger and the merger agreement by written consent on August 19, 1999.

    On August 21 and 22, the parties and their counsel finalized the transaction
documents and completed their due diligence procedures.

    On August 23, 1999, the parties executed the definitive merger agreement and
issued a joint press release announcing the transaction.

EXCHANGE OF FINANCIAL FORECASTS

    As part of its business planning cycle, management of GSI from time to time
has prepared internal financial forecasts regarding its anticipated future
operations. In the course of the discussions described in "Background of the
Merger," GSI provided certain of these internal forecasts to Tyco and its
financial advisor.

    The internal financial forecasts regarding GSI prepared by GSI management
reflected the following forecasted information:

<TABLE>

2001............................     47.9 million      3.9 million      2.2 million       0.17
</TABLE>

    GSI's forecasts were prepared for internal budgeting and planning purposes
only and not with a view to public disclosure or compliance with published
guidelines of the SEC or the guidelines established by the American Institute of
Certified Public Accountants regarding projections or forecasts. While presented
with numerical specificity, the forecasts are based upon a variety of

                                       18
<PAGE>
assumptions relating to the business of GSI and are inherently subject to
significant uncertainties and contingencies that are beyond the control of the
management of GSI. These include the impact of general economic and business
conditions, the competitive environment in which GSI operates and other factors.
See "Forward-Looking Information" on page   . Accordingly, actual results may
differ materially from those forecasted.

    The inclusion of the forecasts herein should not be regarded as a
representation by GSI or any other person that such forecasts are or will prove
to be correct. As a matter of course, GSI does not make public projections or
forecasts of its anticipated financial position or results of operations. Except
to the extent required under applicable securities laws, GSI does not intend to
make publicly available any update or other revisions to any of the forecasts to
reflect circumstances existing after the date of preparation of such forecasts.

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

    The GSI Board, after careful consideration, has unanimously:

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

    2.  approved the merger and the merger agreement; and

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

    At a meeting held on August 19, 1999, the GSI Board, with the assistance of
GSI's outside financial and legal advisors, considered the legal, financial and
other terms of the merger.

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

    - the opportunity for GSI shareholders to receive a significant premium over
      the existing market price for shares of GSI common stock prior to the
      public announcement of the merger and an even larger premium over the
      average market price for shares of GSI common stock over the three month
      period that preceded the announcement;

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

    - the qualification of the merger as a reorganization for U.S. federal
      income tax purposes, which will permit GSI shareholders to receive Tyco
      common shares in a tax-free exchange;

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

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

    - the possible strategic growth opportunities that might be available to GSI
      absent the merger and the belief, based on review of such opportunities,
      that GSI shareholders would benefit most from the potential business
      combination with Tyco;

                                       19
<PAGE>
    - the larger public float and trading volume of Tyco common shares compared
      to the public float and trading volume of shares of GSI common stock,
      which would provide GSI shareholders the opportunity to gain greater
      liquidity in their investment;

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

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

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

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

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

    - the risk that the merger would not be consummated;

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

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

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

    - the possibility that certain provisions of the merger agreement,
      including, among others, the no solicitation and termination fee payment
      provisions of the merger agreement, might have the effect of discouraging
      other persons potentially interested in merging with or acquiring GSI from
      pursuing such an opportunity; and

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

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

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

                                       20
<PAGE>
to different factors. Based on the factors outlined above, the GSI Board
determined that the merger is fair to and in the best interests of GSI and its
shareholders.

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

    See "Background of the Merger" on page   , "Opinion of Financial Advisor to
GSI" on page   , "Material U.S. Federal Income Tax and Bermuda Tax Consequences"
on page   and "Comparative Stock Prices and Dividends" on page   .

OPINION OF FINANCIAL ADVISOR TO GSI

    GENERAL

    Pursuant to a letter agreement dated as of June 21, 1999, as amended, ING
Barings was engaged to provide GSI with financial advisory services and render
an opinion to the GSI Board as to the fairness to GSI shareholders, from a
financial point of view, of the merger consideration. GSI retained ING Barings
only as an advisor or agent to the GSI Board and not to GSI shareholders or any
other person.

    At the meeting of the GSI Board on August 19, 1999, ING Barings rendered its
oral opinion, subsequently confirmed in writing as of August 23, 1999, to the
effect that as of the date of such opinion, and based upon and subject to the
assumptions, limitations and qualifications set forth in such opinion, the
merger consideration was fair to GSI shareholders from a financial point of
view.

    The full text of ING Barings' opinion is attached to this document as Annex
B. You are urged to read the opinion in its entirety for assumptions made,
procedures followed, other matters considered and limits of the review
undertaken in arriving at the opinion. ING Barings' opinion was prepared for the
GSI Board and addresses only the fairness of the merger consideration to GSI
shareholders from a financial point of view. It does not address the merits of
the underlying decision by the GSI Board to engage in the merger or other
business strategies considered by the GSI Board. ING Barings' opinion does not
constitute a recommendation to any GSI shareholder as to how such shareholder
should vote at the GSI special meeting.

    ING Barings' opinion does not constitute an opinion as to the price at which
GSI common stock will actually trade at any time. The merger consideration was
determined in arms'-length negotiations between GSI and Tyco, in which
negotiations ING Barings advised GSI. GSI imposed no restrictions or limitations
upon ING Barings with respect to the investigations made or the procedures
followed by ING Barings in rendering its opinion.

    In arriving at its opinion, ING Barings reviewed and analyzed, among other
things, the following:

    - the merger agreement and certain related documents and the financial terms
      of the Proposed Transaction set forth therein;

    - GSI's Annual Report on Form 10-K for the fiscal year ended June 30, 1998,
      GSI's Quarterly Report on Form 10-Q for the quarterly period ended March
      31, 1999, and GSI's earnings announcement for the fiscal year ended June
      30, 1999;

    - Tyco's Annual Report on Form 10-K for the fiscal year ended September 30,
      1998 and Tyco's Quarterly Report on Form 10-Q for the quarterly period
      ended June 30, 1999;

    - certain other publicly available information concerning GSI and the
      trading market for GSI common stock;

                                       21
<PAGE>
    - certain other publicly available information concerning Tyco and the
      trading market for Tyco common shares;

    - certain non-public information and other data relating to GSI, its
      business and prospects, including forecasts and projections, provided to
      ING Barings by management of GSI;

    - certain publicly available information concerning certain other companies
      engaged in businesses which ING Barings believed to be generally
      comparable to GSI and the trading markets for certain of such other
      companies' securities;

    - the financial terms of certain recent business combinations which ING
      Barings believed to be relevant; and

    - certain discussions and negotiations among representatives of GSI and
      Tyco.

    ING Barings also met with certain officers and employees of GSI concerning
its business and operations, assets, present condition and prospects and
undertook such other studies, analyses and investigations deemed appropriate.
Included in the information provided to ING Barings were certain financial
projections prepared by GSI management. GSI does not publicly disclose internal
management projections of the type provided to ING Barings in connection with
its engagement and, accordingly, such projections were not prepared with a view
toward public disclosure. The projections so provided were based upon numerous
variables and assumptions which are inherently uncertain, including, without
limitation, factors related to general economic and competitive conditions.
Consequently, actual results could vary significantly from those set forth in
such projections. In rendering its opinion, ING Barings relied upon and assumed
the accuracy and completeness of all of the financial and other information used
by it and did not attempt to independently verify such information, nor did it
assume any responsibility to do so. ING Barings also assumed that the financial
projections supplied to it were reasonably prepared on bases reflecting the best
current estimates and judgments of GSI management as to GSI's future financial
condition and results of operations. ING Barings has not made, nor has it
assumed any responsibility for making, any independent evaluation or appraisal
of GSI's properties, facilities or liabilities. ING Barings relied on the advice
of GSI's counsel as to certain legal matters. ING Barings has also taken into
account its assessment of general economic, market and financial conditions and
its experience in similar transactions, as well as its experience in securities
valuation in general. ING Barings' opinion is necessarily based on economic,
market, financial and other conditions as they existed and can be evaluated on,
and on the information made available to ING Barings as of, the date of its
opinion. It should be understood that, although subsequent developments may
affect its opinion, ING Barings does not have any obligation to update, revise
or reaffirm its opinion as a result of changes in such conditions or otherwise,
although it has reserved the right to withdraw, revise or modify its opinion
based on additional information, which may be provided or obtained by it and
which suggest, in its judgment, a material change in the assumptions upon which
its opinion is based.

    Included in the textual discussion below are summaries of certain of the
statistical information appearing in such discussion presented in a tabular
format. While these tables are presented for the purpose of clarity and ease of
reference, they are not substitutes for, and must be read along with, all of the
information appearing under the captions immediately preceding them as well as
all of the information in this section.

    ANALYSIS OF CERTAIN OTHER PUBLICLY TRADED COMPANIES

    To provide comparative market information, ING Barings compared selected
historical common stock prices, earnings and operating and financial ratios for
GSI to the corresponding data and ratios of certain companies that ING Barings
believed to be generally comparable to GSI and whose securities are
publicly-traded. ING Barings used August 5, 1999 (the last date before there was
a

                                       22
<PAGE>
significant increase in the stock price and trading volume in GSI common stock)
stock prices for these comparable companies and projections based upon First
Call Research Network consensus research analyst estimates. The comparable
companies were chosen because they possess general business, operating and
financial characteristics representative of companies in the industry in which
GSI operates. The comparable companies were:

    - Datascope Corporation

    - EndoSonics Corporation

    - Innerdyne, Inc.

    - Kensey Nash Corporation

    - Maxxim Medical Inc.

    - Mentor Corporation

    - Orthofix International N.V.

    - Vital Signs, Inc.

    The data and ratios ING Barings analyzed included total enterprise value as
a multiple of latest twelve-months' revenues, Earnings Before Interest, Taxes,
Depreciation and Amortization ("EBITDA"), and Earnings Before Interest and Taxes
("EBIT"), and price per share as a multiple of projected calendar year 1999
earnings per share (based upon the First Call Research Network consensus
research analyst estimates). Due to current and projected negative results of
GSI, however, ING Barings focused only on the multiple of latest twelve-months,
estimated calendar year 1999 and estimated calendar year 2000 revenues when
inferring value from its public comparable companies analysis.

    For purposes of its analysis, total enterprise value was calculated as the
aggregate value of the common stock outstanding at June 30, 1999 (treating on a
treasury stock method basis the net shares issuable upon exercise of options and
warrants and other rights of conversion as outstanding), plus book value of debt
and preferred equity, less cash, cash equivalents and marketable securities. The
multiples of enterprise value to latest twelve months' revenue for the
comparable companies ranged from 1.24x to 3.05x, compared to 13.41x for GSI
based on the Tyco common shares issuable in the merger having an assumed value
of $7.50 per GSI share. The multiples of enterprise value to revenues for the
comparable companies ranged from 1.05x to 2.36x for calendar year 1999 and from
0.95x to 2.07x for calendar year 2000. GSI's enterprise value to revenues
multiple decreased from 7.46x for calendar year 1999 to 2.96x for calendar year
2000.

    REVENUE MULTIPLE VALUATION

    ING Barings calculated total enterprise value (for purposes of this
analysis) by applying the median multiple stated above to GSI's latest
twelve-months and estimated calendar year 1999 and 2000 revenues, subtracted
total debt outstanding as of June 30, 1999, and added cash, cash equivalents and
marketable securities as of June 30, 1999, to arrive at an implied equity value
for GSI. ING Barings then divided each implied equity value figure by the 14.9
million fully diluted shares outstanding as of June 30, 1999. The implied per
share value for GSI common stock was $2.22 based on the LTM revenues multiple of
2.0x, $2.79 based on calendar year 1999 revenues multiple of 1.8x and $4.48
based on calendar year 2000 revenues multiple of 1.5x.

    In arriving at its opinion, ING Barings took into account that the multiples
available to GSI, based on the merger consideration, compared favorably to the
multiples derived from the comparable companies. No other company utilized in
ING Barings' analysis of the comparable publicly traded companies is identical
to GSI. Accordingly, such analysis necessarily involves complex considerations
and judgments concerning differences in GSI's financial and operating
characteristics and other factors that could affect GSI's public trading value
and the public trading value of other companies included in such analysis.

    COMPARABLE TRANSACTION ANALYSIS

    ING Barings reviewed 12 selected acquisitions that it believed to be
generally comparable. The comparable transactions were:

    For purposes of this analysis, total enterprise value was calculated as the
aggregate purchase price of equity (in the case of stock purchases), or the
aggregate purchase price of assets (in the case of asset purchases), plus book
value of debt and preferred equity, less cash, cash equivalents and marketable
securities. For each of the comparable transactions, ING Barings' calculated a
total enterprise value to latest twelve-months' revenues multiple, total
enterprise value to latest twelve-months' EBITDA, and total enterprise value to
latest twelve-months' EBIT. In addition, ING Barings calculated equity value to
latest twelve-months' net income and book value. Due to current and projected
negative results of GSI, however, ING Barings focused only on the multiple of
latest twelve-months revenue when inferring value from its transaction
comparables analysis. The transaction comparables analysis resulted

                                       24
<PAGE>
in a median total enterprise value to latest twelve-months' revenue multiple of
3.3x, resulting in a total enterprise value for GSI of $22.8 million. After
subtracting total debt outstanding as of June 30, 1999, and then adding cash,
cash equivalents and marketable securities as of June 30, 1999, ING Barings
arrived at an implied equity value of $42.0 million for GSI, based on the merger
consideration. ING Barings then divided GSI's implied equity value figure by the
fully diluted shares outstanding as of June 30, 1999, to reach an implied share
value for GSI common stock of $2.82.

    In addition to revenue multiples, ING Barings analyzed the 1 and 30 day
takeover premiums for the comparable transactions. In terms of its relation to
the stock price the day before the merger announcement, the median multiples for
the 1 and 30 trading premiums were 1.214x and 1.475x, respectively. Multiplying
these multiples by the $4.00 pre-announcement stock price and the number of
fully-diluted shares, ING Barings derived implied equity values of $72.4 million
and $87.9 million. ING Barings then divided GSI's implied equity value figure by
the fully diluted shares outstanding as of June 30, 1999, to reach an implied
share value for GSI common stock of $4.86 and $5.90 for the 1 and 30 day trading
premiums, respectively, compared to the merger consideration of $7.50 per share.

(c) Based on August 5, 1999 stock prices (the last date before there was a
    significant increase in the stock price and trading volume in GSI common
    stock).

    In arriving at its opinion, ING Barings took into account that the multiples
available to GSI, based on the merger consideration, compared favorably to the
multiples derived for the selected transactions. No transaction utilized in the
comparable transaction analysis is identical to the merger. Accordingly, such
analysis necessarily involves complex considerations and judgments concerning
differences in GSI's financial and operating characteristics and other factors
that could affect the acquisition value of the companies to which they are being
compared.

    DISCOUNTED CASH FLOW ANALYSIS

    ING Barings performed a discounted cash flow analysis for the three and a
half year period ending with calendar year 2002 on GSI's stand-alone unlevered
free cash flow, using financial projections provided by GSI management.
Unlevered free cash flows were calculated as: (A) EBIT; (B) less taxes; (C) plus
depreciation and amortization; (D) less capital expenditures; (E) less net
changes in working capital. ING Barings calculated terminal values by applying a
range of estimated EBIT multiples of 14x to 16x to projected EBIT of GSI in the
calendar year 2002. The unlevered free cash flows and terminal values were then
discounted to the present value using a range of discount rates from 13.8% to
15.8%. This range was selected because GSI's weighted average cost of capital
was 14.8%. After deriving total enterprise values from this analysis, ING
Barings derived two separate implied equity values. In both cases, cash, cash
equivalents and marketable securities were added and total debt outstanding was

                                       25
<PAGE>
subtracted from enterprise value. However, in one case 90% of the estimated
lawsuit receivable due to GSI from the court verdict against Origin Medsystems,
Inc. was discounted back one year at GSI's weighted average cost of capital
(14.8%) and was added to derive implied equity value. Based on this analysis
assuming a 14.8% discount rate, an EBIT terminal value multiple range between
14x--16x and using management estimates, ING Barings calculated values per share
of GSI common stock ranging from $7.45 to $8.34 with the lawsuit receivable
included and from $6.40 to $7.29 excluding the lawsuit receivable.

    COMMON STOCK TRADING PRICE HISTORY

    ING Barings also analyzed the value of the merger consideration as a premium
to the 5, 15, 30, and 90-day average price of GSI common stock as well as to the
52 week high and low. The information in the table below was presented solely to
provide the GSI Board with background information regarding GSI stock price

    The summary set forth above describes the principal elements of the
presentation made by ING Barings to the GSI Board on August 19, 1999. The
presentation of a fairness opinion involves various determinations as to the
most appropriate and relevant methods of financial analysis and the application
of these methods to the particular circumstances and, therefore, such an opinion
is not readily susceptible to summary description. Each of the analyses
conducted by ING Barings was carried out in order to provide a different
perspective on the transaction and to add to the total mix of information
available. ING Barings did not form a conclusion as to whether any individual
analysis, considered in isolation, supported or failed to support an opinion as
to fairness from a financial point of view. Rather, in reaching its conclusion,
ING Barings considered the results of the analyses in light of each other and
ultimately reached its opinion based on the results of all analyses taken as a
whole. ING Barings did not place particular reliance or weight on any individual
analysis, but instead concluded that its analyses, taken as a whole, supported
its determination. Accordingly, notwithstanding the separate factors summarized
above, ING Barings believes that its analyses must be considered as a whole and
that selecting portions of its analysis and the factors considered by it,
without considering all analyses and factors, could create an incomplete or
misleading view of the evaluation process underlying its opinion.

    In performing its analyses, ING Barings made numerous assumptions with
respect to industry performance, business and economic conditions and other
matters. The analyses performed by ING

                                       26
<PAGE>
Barings are not necessarily indicative of actual values or future results, which
may be significantly more or less favorable than suggested by such analyses.

    Pursuant to the terms of the engagement letter dated June 21, 1999, and
amendment dated August 9, 1999, GSI agreed to pay ING Barings:

    - $75,000 as a retainer fee;

    - $250,000 at the time of execution of the merger agreement; and

    - 1% of the aggregate consideration received by GSI shareholders upon the
      consummation of the merger, against which any fees previously paid to ING
      Barings under the foregoing items will be credited.

    GSI has also agreed to reimburse ING Barings promptly for all out-of-pocket
expenses, including the reasonable fees and out-of-pocket expenses of counsel,
incurred by ING Barings in connection with its engagement, and to indemnify ING
Barings and related persons against liabilities in connection with its
engagement, including liabilities under the federal securities laws. The terms
of the fee arrangement with ING Barings were negotiated at arms'-length between
GSI and ING Barings.

    ING Barings is a full service securities firm that engages in securities
trading and brokerage activities, in addition to providing investment banking
services. In the ordinary course of its business, ING Barings, as a market maker
or otherwise, may trade or otherwise effect transactions in the securities of
GSI and Tyco and, accordingly, may at any time hold a long or short position in
such securities.

REASONS OF TYCO FOR THE MERGER

    At a meeting of the Tyco Board held on August 9, 1999, the Tyco Board
determined that the acquisition of GSI was in keeping with its corporate
strategy of complementing its internal growth with acquisitions that are likely
to benefit from cost reductions and synergies when combined with Tyco's existing
operations and that are expected to be accretive to earnings per share.

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

    - the expectation that GSI's businesses could be readily integrated with
      Tyco's healthcare products business, enabling Tyco to broaden the line of
      surgical supplies offered to its customers;

    - the patent litigation between GSI and a subsidiary of Tyco and the
      prospect that if the judgment in this litigation in favor of GSI were
      upheld on appeal, Tyco could be forced permanently to discontinue
      manufacturing and marketing of certain balloon dissection devices found at
      trial to infringe on GSI's patents;

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

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

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

                                       27

INTERESTS OF CERTAIN PERSONS IN THE MERGER

    GENERAL

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

    STOCK OPTIONS HELD BY GSI EXECUTIVE OFFICERS AND NON-EMPLOYEE DIRECTORS

    As of October   , 1999, GSI's directors and executive officers collectively
beneficially own options to acquire an aggregate of     shares of GSI common
stock.

    Under the merger agreement, following the merger each option to acquire
stock of GSI will become the right to receive the difference in cash between
$7.50 and the exercise price of the option for each share subject to the option.
This amount will be payable whether or not the option is vested at the time of
the merger. Options whose exercise price equals or exceeds $7.50 will be
cancelled. The cash amounts, before income taxes, that the principal executive
officers of GSI will receive for their options as a result of the merger are:
Gregory D. Casciaro--$1,544,004.79; Roderick A. Young-- $746,196.84; James E.
Jervis--$719,969.77; Stephen J. Bonelli--$836,595.32; and Ferolyn T. Powell--
$548,125.00. The cash amounts, before income taxes, that the non-employee
directors of GSI will receive for their options as a result of the merger are:
David W. Chonette--$207,091.27; Thomas J. Fogarty--$87,811.84; Paul
Goeld--$230,980.42; James R. Sulat--$46,332.00; and Mark A. Wan-- $212,239.27.
The amounts in this paragraph assume that the exchange ratio has not been fixed
at 0.0913 (pre-split), in the circumstances described under "Certain Provisions
of the Merger Agreement--Termination" on page 44. If the exchange ratio were
fixed at 0.0913 (pre-split), these amounts would be lower.

    INDEMNIFICATION

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

    OTHER

    Certain officers of GSI have been awarded retention bonuses to incentivize
them to continue their employment with GSI until the merger is consummated.
These bonuses, which are payable following consummation of the merger if the
officers remain employed by GSI through that time, are as follows: Mr.
Casciaro--$153,000; Mr. Bonelli--$60,000; Mr. Jervis--$60,000; and Ms.
Powell--$60,000.

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

    U.S. FEDERAL INCOME TAX CONSEQUENCES

    The following discussion is a summary of the material U.S. federal income
tax consequences of the exchange of GSI common stock for Tyco common shares and
the ownership of Tyco common shares. The discussion which follows is based on
the U.S. Internal Revenue Code, Treasury Regulations

                                       28
<PAGE>
promulgated thereunder, administrative rulings and pronouncements and judicial
decisions as of the date hereof, all of which are subject to change, possibly
with retroactive effect.

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

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

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

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

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

    - a trust

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

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

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

    1. CONSEQUENCES OF THE MERGER

    In the opinion of PricewaterhouseCoopers LLP and Venture Law Group, A
Professional Corporation, the material U.S. federal income tax consequences that
will result from the merger are as follows:

a.  The merger will constitute a reorganization within the meaning of Section
    368 of the U.S. Internal Revenue Code.

b.  A GSI shareholder, other than a GSI shareholder that is a "5% transferee
    shareholder" within the meaning of U.S. Treasury Regulation 1.367(a)-3, will
    not recognize any income, gain or loss as a result of the receipt of Tyco
    common shares in exchange for GSI common stock pursuant to the merger,
    except for cash received in lieu of a fractional Tyco common share.

c.  The tax basis to a GSI shareholder of the Tyco common shares received in
    exchange for GSI common stock pursuant to the merger, including any
    fractional share interest in Tyco common

                                       29
<PAGE>
    shares for which cash is received, will equal such GSI shareholder's tax
    basis in the GSI common stock surrendered in exchange therefor.

d.  The holding period of a GSI shareholder for the Tyco common shares received
    pursuant to the merger will include the holding period of the GSI common
    stock surrendered in exchange therefor.

e.  A GSI shareholder who is a U.S. Holder and who receives cash in lieu of a
    fractional share interest in Tyco common shares pursuant to the merger will
    be treated as having received such cash in exchange for such fractional
    share interest and generally will recognize capital gain or loss on such
    deemed exchange in an amount equal to the difference between the amount of
    cash received and the basis of the GSI stock allocable to such fractional
    share. Non-U.S. Holders who receive cash in lieu of a fractional share
    interest in Tyco common shares will not be subject to United States income
    or withholding tax except as set forth in paragraph 3.b below.

f.  No income, gain or loss will be recognized by Tyco, General Acquisition, GSI
    or General Sub as a result of the transfer to GSI shareholders of the Tyco
    common shares provided by Tyco to General Acquisition pursuant to the
    merger.

    Consummation of the merger is conditioned upon the receipt of opinions to
this effect as of the consummation of the merger. If delivery of such opinions
is waived notwithstanding a material change in the tax consequences of the
merger, GSI and Tyco will recirculate and resolicit this document. Such opinions
are and will be based on facts existing as of the date hereof and as of the
consummation of the merger and on certain representations as to factual matters
made by Tyco, General Acquisition and GSI. Such representations, if incorrect in
certain material respects, could jeopardize the conclusions reached in the
opinions. Such opinions are not binding on the U.S. Internal Revenue Service or
the courts.

    2. TRANSFER TAXES

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

    3. OWNERSHIP OF TYCO COMMON SHARES

    a. U.S. Holders

    DISTRIBUTIONS

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

                                       30
<PAGE>
are corporations generally will not be entitled to claim a dividends received
deduction with respect to distributions by Tyco, because Tyco is a foreign
corporation.

    DISPOSITION

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

    INFORMATION REPORTING AND BACKUP WITHHOLDING

    Certain U.S. Holders may be subject to information reporting with respect to
payments of dividends on, and the proceeds of the disposition of, Tyco common
shares. U.S. Holders who are subject to information reporting and who do not
provide appropriate information when requested may be subject to backup
withholding at a 31% rate. U.S. Holders should consult their tax advisors
regarding the imposition of backup withholding and information reporting with
respect to distributions on, and dispositions of, Tyco common shares.

    b. Non-U.S. Holders

    DISTRIBUTIONS AND DISPOSITION

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

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

    INFORMATION REPORTING AND BACKUP WITHHOLDING

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

    BERMUDA TAX CONSEQUENCES

    In the opinion of Appleby, Spurling & Kempe, attorneys in Bermuda for Tyco,
there will be no Bermuda income, corporation or profits tax, withholding tax,
capital gains tax, capital transfer tax, estate duty or inheritance tax payable
in respect of the delivery of Tyco common shares to GSI shareholders in exchange
for GSI common stock pursuant to the merger. In addition, as of the date hereof,
there is no Bermuda income, corporation or profits tax, withholding tax, capital
gains tax, capital transfer tax, estate duty or inheritance tax payable in
respect of capital gains realized on a disposition of Tyco common shares or in
respect of distributions by Tyco with respect to Tyco common shares.
Furthermore, Tyco has received from the Minister of Finance of Bermuda under the
Exempted Undertakings Tax Protection Act of 1966 an undertaking that, in the
event of there being enacted in Bermuda any legislation imposing any tax
computed on profits or income, including any dividend or capital gains
withholding tax, or computed on any capital assets, gain or appreciation or any
tax in the nature of an estate or inheritance tax or duty, the imposition of
such tax shall not be applicable to Tyco or any of its operations, nor to its
common shares nor to obligations of Tyco until the year 2016. This undertaking
applies to Tyco common shares. It does not, however, prevent the application of
Bermuda taxes to persons ordinarily resident in Bermuda.

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

ACCOUNTING TREATMENT

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

CERTAIN LEGAL MATTERS

    General Acquisition and GSI have committed to use their reasonable best
efforts to take whatever actions are required to obtain necessary regulatory
approvals.

    The Hart-Scott-Rodino Antitrust Improvements Act of 1976 prohibits Tyco and
GSI from completing the merger until certain information and materials have been
furnished to the U.S. Federal Trade Commission and the Antitrust Division of the
U.S. Department of Justice and a required waiting period is observed. This
waiting period will expire on             , 1999 unless terminated earlier. Even
after the waiting period expires or terminates, the FTC or the Antitrust
Division could take such action under the antitrust laws as it deems necessary
or desirable in the public interest, including seeking divestiture of
substantial assets of Tyco or GSI. Neither Tyco nor GSI believes that
consummation of the merger will result in a violation of any applicable
antitrust laws. However, there is no assurance that a challenge to the merger on
antitrust grounds will not be made or, if such a challenge is made, of the
result.

    Tyco and GSI do not believe that any additional material governmental
filings in the United States, other than the agreement of merger in California,
are required with respect to the merger.

                                       32
<PAGE>
U.S. FEDERAL SECURITIES LAW CONSEQUENCES

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

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

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

    - the number of shares a GSI affiliate may sell, together with certain
      related persons and certain persons acting in concert, within any
      three-month period for purposes of Rule 145 may not exceed the greater of
      1% of the outstanding Tyco common shares or the average weekly trading
      volume of such stock during the four calendar weeks preceding such sale,
      and

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

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

DIVIDENDS

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

STOCK EXCHANGE LISTING

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

DISSENTERS' RIGHTS

    If the merger is approved by the required vote at the special meeting of GSI
shareholders, a holder of record of shares of GSI common stock who does not vote
in favor of the merger and who follows the procedures set forth in Chapter 13 of
the California General Corporation Law may be entitled to exercise dissenters'
rights under California law. Dissenter's rights will, however, only be

                                       33
<PAGE>
available in connection with the merger if holders of more than five percent
(5%) of GSI's outstanding shares of common stock elect to exercise such rights.
If dissenter's rights are determined to be available in connection with the
merger, such rights entitle the holder to require GSI to purchase the holder's
shares for cash at their fair market value. The fair market value of the GSI
common stock will be determined as of the day before the first announcement of
the terms of the merger, excluding any element of value arising from the
accomplishment or expectation of the merger. The following is a summary
description of the provisions of the applicable California law. This summary is
complete in all material respects but should be read with the full text of the
applicable law, a copy of which is attached hereto as Annex C. Any holder of
shares of GSI common stock intending to exercise statutory dissenters' rights is
urged to review Annex C carefully and to consult with legal counsel so as to
assure strict compliance with its provisions.

    A vote in favor of the merger agreement and the merger will constitute a
waiver of dissenters' rights. If a GSI shareholder delivers a proxy that has
been left blank, the proxy will be voted for the approval and adoption of the
merger agreement, unless the proxy is revoked before the special meeting.
Therefore, any GSI shareholder that intends to exercise dissenters' rights and
to vote by proxy should not leave the proxy blank. The shareholder should either
vote against the merger or abstain from voting for or against the approval and
adoption of the merger agreement.

    NOTIFICATION OF APPROVAL AND ADOPTION OF MERGER AGREEMENT

    Within 10 days after approval and adoption of the merger agreement by the
GSI shareholders, GSI must mail a notice of the approval to holders of shares of
GSI common stock which were not voted in favor of the merger, together with a
statement of the price determined by GSI to represent the fair market value of
the shares for which dissenters' rights remain available, a brief description of
the procedures to be followed in order for the holder to pursue dissenters'
rights, and a copy of Sections 1300 to 1304 of Chapter 13. The statement of
price by GSI constitutes an offer by GSI to purchase all shares for which
dissenters' rights remain available at the stated amount. Only a holder of
record of shares of GSI common stock on the record date (or the holder's duly
appointed representative) is entitled to exercise dissenters' rights.

    ELECTING DISSENTERS' RIGHTS

    To exercise dissenters' rights, the record holder of GSI common stock must

    - not vote to approve and adopt the merger agreement, and

    - within 30 days after the date the approval notice is mailed to the holder,
      deliver a written demand for purchase demanding that GSI purchase the
      holder's shares of common stock and a statement as to what the holder
      claims to be the fair market value of such shares.

    The statement of the fair market value of the shares of GSI common stock
constitutes an offer by the shareholder to sell the shares of GSI at that price.

    The written demand for purchase must be delivered to GSI at 10460 Bubb Road,
Cupertino, California 95014, Attention: Corporate Secretary.

    If GSI and the dissenting holder agree upon the purchase price of the
shares, the dissenting holder is entitled to the agreed upon price with interest
thereon at the legal rate on judgments from the date of such agreement. Payment
for the dissenting shares must be made within 30 days after the later date of
such agreement or the date on which all statutory and contractual conditions to
the merger are satisfied, and is subject to surrender to GSI of the certificates
for the dissenting shares.

                                       34
<PAGE>
    APPRAISAL PROCEEDING BY CALIFORNIA COURT

    If GSI and the record holder of GSI common stock fail to agree upon the fair
market value of such holder's shares of GSI common stock, then within six months
after the date of the approval notice from GSI, any shareholder who has not
voted in favor of approval and adoption of the merger agreement and who has made
a valid written demand for purchase may file a complaint in superior court
requesting a determination as to whether the shares are dissenting shares or as
to the fair market value of such holder's shares of GSI common stock, or both.

    EFFECT OF EXERCISE OF DISSENTERS' RIGHTS ON VOTING AND RIGHT TO DIVIDENDS

    Any shareholder who has duly exercised dissenters' rights in compliance with
California law will not, after the effective time of the merger, be entitled to
vote the dissenting shares for any purpose. The dissenting shares will not be
entitled to the payment of dividends or other distributions, other than those
payable or deemed payable to shareholders of record as of the date prior to the
effective time of the merger.

    LOSS, WAIVER OR WITHDRAWAL OF DISSENTERS' RIGHTS

    If a holder of shares of GSI common stock who demands the purchase of shares
under Chapter 13 fails to perfect, or effectively withdraws or loses the right
to such purchase, such holder will be entitled to receive the consideration
otherwise payable pursuant to the merger.

    Dissenting shares lose their status as dissenting shares if:

    - the merger is abandoned;

    - the shares are transferred prior to their submission for the required
      endorsement;

    - the dissenting shareholder fails to make a timely written demand for
      purchase, along with a statement of fair market value;

    - the dissenting shares are voted in favor of the merger;

    - the dissenting shareholder and GSI do not agree upon the status of the
      shares as dissenting shares or do not agree on the purchase price, but
      neither GSI nor the shareholder files a complaint or intervenes in a
      pending action within six months after mailing of the approval notice; or

    - with GSI's consent, the shareholder delivers to GSI a written withdrawal
      of the shareholder's written demand for purchase.

                   CERTAIN PROVISIONS OF THE MERGER AGREEMENT

GENERAL

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

EFFECTIVE TIME

    Promptly after the satisfaction or waiver of the conditions to the merger
set forth in the merger agreement, GSI and General Sub will file an agreement of
merger with the Secretary of State of the State of California, as prescribed by
California law. The effect of this filing is that General Sub will merge with
and into GSI, and GSI will become an indirect wholly-owned subsidiary of Tyco.

MERGER CONSIDERATION

    GENERAL

    As a result of the merger, all outstanding shares of GSI common stock will
be converted into Tyco common shares in accordance with the terms of the merger
agreement.

    THE EXCHANGE RATIO

    GSI's shareholders will receive a fraction of a Tyco common share for each
share of GSI common stock, based on an exchange ratio determined by dividing
$7.50 by the average share price computed by taking the average of the daily
volume weighted selling prices of Tyco common shares on the New York Stock
Exchange over the five trading days ending four trading days before the special
meeting of GSI shareholders.

    If the average share price is less than $82.15 (pre-split), General
Acquisition may call off the merger prior to the time of the GSI special
meeting, unless on or before the second trading day prior to the date of the GSI
special meeting, GSI agrees to an exchange ratio equal to 0.0913 (pre-split). If
GSI agrees to fix the exchange ratio at 0.0913, then General Acquisition will
not have the right to call off the merger and the exchange ratio will be 0.0913.

    A GSI shareholder will not receive a fraction of a Tyco common share in the
merger. Any fractional Tyco common share will be paid in cash equal to the
fraction multiplied by the last reported sale price of a Tyco common share on
the last trading day prior to the time of the merger.

    BASIS OF GSI'S DETERMINATION TO FIX THE EXCHANGE RATIO

    The average share price will not be known until the close of trading on
October   , 1999, the fourth trading day before the GSI special meeting. GSI has
made no decision as to whether, if the average share price were less than $82.15
(pre-split), it would agree to fix the exchange ratio at 0.0913 (pre-split). In
the event such decision is required to be made, the GSI Board would consult with
its management and legal and financial advisors and take into account,
consistent with its fiduciary duties, all relevant facts and circumstances that
exist at such time, including:

    - the amount of the decrease in the value of Tyco common shares to be
      received in the merger if the exchange ratio is fixed at 0.0913;

    - general market, economic and business conditions;

                                       36
<PAGE>
    - management's assessment of the potential benefits expected to be realized
      by combining the operations of GSI and Tyco;

    - other opportunities available to GSI; and

    - whether the proposed merger continues to be in the best interests of GSI
      and its shareholders.

    Any decision of the GSI Board to fix the exchange ratio at 0.0913 will be
made prior to the GSI special meeting. Approval of the merger agreement by the
GSI shareholders will constitute approval of such decision. GSI has not
considered whether it will seek a revised fairness opinion if the average share
price is less than $82.15 and it elects to fix the exchange ratio at 0.0913. GSI
does not currently intend to resolicit proxies if it determines to proceed with
the merger at an exchange ratio of 0.0913.

    STOCK OPTIONS

    The merger agreement provides that each option to purchase shares of GSI
common stock issued to employees and directors of GSI and outstanding at the
time the merger is completed will receive an amount in cash equal to the
positive difference between (i) the number of shares of GSI common stock for
which the option was exercisable at the time of the merger multiplied by the
product of the exchange ratio and the average share price and (ii) the aggregate
exercise price of the shares of GSI common stock purchasable pursuant to the
option. Any GSI stock option the exercise price of which as of the time of the
consummation of the merger equals or exceeds the product of the exchange ratio
and the average share price will be cancelled and be of no further force and
effect as of the effective time of the merger.

EXCHANGE OF GSI COMMON STOCK

    As soon as reasonably practicable after the consummation of the merger,
General Acquisition will instruct ChaseMellon Shareholder Services LLC, as
exchange agent, to mail to each holder of record of GSI common stock a letter of
transmittal and instructions as to how to surrender certificates of GSI common
stock in exchange for Tyco common shares and payment for any fractional shares.
GSI SHAREHOLDERS SHOULD NOT RETURN STOCK CERTIFICATES WITH THE ENCLOSED PROXY.

    Holders of certificates previously representing GSI common stock will not be
paid dividends or distributions on the Tyco common shares and will not be paid
cash in lieu of a fractional Tyco common share until such certificates are
surrendered to ChaseMellon for exchange. When such certificates are surrendered,
any unpaid dividends declared by Tyco after the consummation of the merger and
any cash in lieu of a fractional Tyco common share will be paid without
interest. For all other corporate purposes, certificates that represented shares
of GSI common stock prior to the consummation of the merger will represent from
and after the consummation of the merger, the number of Tyco common shares and
cash in respect of fractional shares, into which such shares of GSI common stock
are actually converted in the merger.

    ChaseMellon will deliver Tyco common shares in exchange for lost, stolen or
destroyed certificates if the owner of such certificates signs an affidavit of
loss, theft or destruction, as appropriate. General Acquisition may also, in its
discretion, require the holder of such lost, stolen or destroyed certificates to
deliver a bond in a reasonable sum as indemnity against any claim that might be
made against Tyco, General Acquisition or ChaseMellon with respect to alleged
lost, stolen or destroyed certificates.

REPRESENTATIONS AND WARRANTIES

    GSI and General Acquisition have made various customary mutual
representations and warranties in the merger agreement about themselves and
their subsidiaries, as well as, in the case of General Acquisition, Tyco and its
other subsidiaries. General Acquisition's representations and warranties have
been unconditionally guaranteed by Tyco.

                                       37
<PAGE>
    In addition, GSI represented that the GSI Board of Directors, prior to the
execution of the merger agreement, authorized an amendment to the GSI
shareholder rights agreement to render the GSI shareholder rights agreement
inapplicable to the merger agreement and the transactions contemplated thereby.
GSI appropriately amended the GSI shareholder rights agreement as of August 23,
1999.

CONDUCT OF BUSINESS BY GSI

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

    1.  amend or otherwise change GSI's Amended and Restated Articles of
       Incorporation or Bylaws;

    2.  issue, sell, pledge, dispose of or encumber, or authorize the issuance,
       sale, pledge, disposition or encumbrance of, any shares of capital stock
       of any class, or any options, warrants, convertible securities or other
       rights of any kind to acquire any ownership interest in GSI or any of its
       subsidiaries or affiliates, subject to certain exceptions in the case of
       GSI's equity-based incentive plans;

    3.  sell, pledge, dispose of or encumber any assets of GSI or any of its
       subsidiaries, other than in the ordinary course of business and in a
       manner consistent with past practice or pursuant to other limited
       exceptions;

    4.  -  declare, set aside, make or pay any dividend or other distribution in
           respect of any of its capital stock,

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

       -  amend the terms or change the period of exercisability of, acquire or
          permit any subsidiary to amend the terms or change the period of

       action which would make any of the representations or warranties of GSI
       contained in the merger agreement untrue or incorrect or prevent GSI from

CONDUCT OF BUSINESS BY TYCO

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

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

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

    3.  declare, set aside, make or pay any dividend or other distribution on
       any of its capital stock, other than a previously declared two-for-one
       stock split in the form of a stock distribution and regular quarterly
       cash dividends and other than a dividend to Tyco by a wholly owned
       subsidiary of Tyco;

    4.  change accounting policies or procedures; or

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

NO SOLICITATION

    GSI has agreed that it will not solicit or encourage the initiation of any
inquiries or proposals regarding any other merger, sale of assets, sale of
shares of capital stock or similar transaction with a third party in which such
party would acquire more than 30% of the outstanding shares of any class of
GSI's equity securities or more than 30% of the outstanding equity securities of
GSI or the surviving entity in a merger with GSI or would acquire more than 30%
of the fair market value of GSI's assets. Any of the foregoing transactions are
referred to in this document as an "Alternative Transaction" and any proposal
from a third party to effect an Alternative Transaction is referred to as an
"Acquisition Proposal."

                                       39
<PAGE>
    Until the GSI shareholders approve and adopt the merger agreement, if the
GSI Board, following consultation with independent legal counsel, determines
that such action is reasonably likely to be required to discharge properly its
fiduciary duties, the GSI Board, after notice to General Acquisition, is
permitted to:

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

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

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

    2.  consider and negotiate such Superior Proposal.

    Notwithstanding the foregoing points 1 and 2, GSI and the GSI Board, except
to the extent that the GSI Board reasonably determines in good faith and after
consultation with independent legal counsel that it is reasonably likely to be
required to act to the contrary in order to properly discharge its fiduciary
duties, may not in any circumstance withdraw or modify in a manner adverse to
General Acquisition or General Sub the GSI Board's approval of the merger.

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

    The merger agreement expressly provides that the foregoing covenants shall
not prohibit GSI from taking or disclosing to its shareholders a position
regarding an Alternative Transaction or Acquisition Proposal or from making any
disclosure to its shareholders required by law.

    GSI has agreed

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

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

    3.  not redeem the rights under, or waive or amend any provisions of, the
       GSI shareholder rights agreement that would facilitate the consummation
       of any Acquisition Proposal or Alternative Transaction.

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

CERTAIN OTHER COVENANTS

    CONSENTS; APPROVALS

    General Acquisition and GSI will each use its reasonable best efforts to
obtain all consents, waivers, approvals, authorizations or orders, and General
Acquisition and GSI will make or cause to be

                                       40
<PAGE>
made all filings, required in connection with the authorization, execution and
delivery of the merger agreement and the consummation by each of them of the
transactions contemplated thereby.

    INDEMNIFICATION AND INSURANCE

    For six years following consummation of the merger, the Articles of
Incorporation and By-laws of the surviving corporation will contain the same
indemnification provisions as currently set forth in the Amended and Restated
Articles of Incorporation and By-laws of GSI and such provisions will not be
modified in any manner adverse to the rights of individuals who were directors,
officers, employees or agents of GSI at the consummation of the merger unless
otherwise required by law.

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

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

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

    NOTIFICATION OF CERTAIN MATTERS

    General Acquisition and GSI will each give each other prompt notice of the
occurrence or nonoccurrence of any event which would be reasonably expected to
cause any representation or warranty contained in the merger agreement to be
materially untrue or inaccurate, or any failure of GSI, General Acqusition or
General Sub materially to comply with or satisfy any covenant, condition or
agreement contained in the merger agreement.

    FURTHER ACTION/TAX TREATMENT

    The parties to the merger agreement will use all reasonable efforts to take,
or cause to be taken, all actions and to do all other things necessary, proper
or advisable to consummate and make effective as promptly as practicable the
transactions contemplated by the merger agreement, to obtain in a timely manner
all necessary waivers, consents and approvals and to effect all necessary
registrations and filings, and otherwise to satisfy or cause to be satisfied all
conditions precedent to each of their obligations under the merger agreement.
However, Tyco is under no obligation to agree to divest, abandon, license, enter
into, modify, maintain or renew any contract arrangement regarding or take
similar action with respect to any assets of Tyco or GSI or any of their
respective subsidiaries. In addition, General Acquisition, General Sub and GSI
have each agreed to use their reasonable best

                                       41
<PAGE>
efforts to cause the merger to qualify as a reorganization under the provisions
of Section 368 of the U.S. Internal Revenue Code, as specified in the merger
agreement, and will not, both before and after consummation of the merger, take
any actions which might reasonably be expected to prevent the merger from so
qualifying.

    PUBLIC ANNOUNCEMENTS

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

    TYCO COMMON SHARES

    Tyco has guaranteed to take all actions necessary to transfer to General
Acquisition the Tyco common shares to be delivered by General Acquisition to the
GSI shareholders in the merger. Tyco also has guaranteed to use its best efforts
to list on the NYSE the Tyco common shares to be delivered in the merger.

    RIGHTS AGREEMENT

    The GSI Board has agreed to take all necessary action to render the rights
under the GSI shareholder rights agreement inapplicable to the merger agreement
and the merger.

    4.  GOVERNMENTAL ACTIONS. No action or proceeding has been instituted,
       pending or threatened by any governmental authority or administrative

       prevents or seeks to prevent the consummation of the merger, prevents or

TERMINATION

    CONDITIONS TO TERMINATION

    The merger agreement may be terminated at any time prior to the consummation

GSI shareholders of the merger agreement:

    1.  by mutual written consent duly authorized by the Boards of Directors of
       both GSI and General Acquisition;

    2.  by either of General Acquisition or GSI, if the merger has not been
       consummated by February 28, 2000, other than for reasons set forth in 4
       below; PROVIDED, HOWEVER, that this right to terminate is not available
       to the party whose failure to fulfill any of its obligations under the
       merger agreement caused the merger not to be consummated before February
       28, 2000;

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

    4.  by either of General Acquisition or GSI, if GSI shareholders do not
       approve and adopt the merger agreement at the GSI special meeting;
       provided, however, that this right to terminate is not available to GSI
       if GSI fails to call the GSI shareholder meeting;

    5.  by General Acquisition, if, whether or not permitted to do so by the
       merger agreement, GSI or the GSI Board:

          required by law, rule or regulation that has the effect of any of the
          foregoing;

<PAGE>
    6.  by either of General Acquisition or GSI:

       -  if any representation or warranty of GSI, General Acquisition or
          General Sub set forth in the merger agreement was untrue when made or
          has become untrue, or

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

       such that in either case, the conditions to the terminating party's

       the Merger" would not be satisfied; PROVIDED THAT, if such
       misrepresentation or breach is curable prior to February 28, 2000 and the

          enter into a definitive agreement with respect to a Superior Proposal,

       -  within two full business days of receipt of GSI's notification,

          determines, in good faith after consultation with its financial

       -  GSI has complied in all material respects with its no solicitation
          obligations as described on page   .

    8.  by General Acquisition, prior to the GSI special meeting, if the average
       share price is less than $82.15 (pre-split), unless on or before the
       second trading day prior to the GSI special meeting, GSI agrees to an
       exchange ratio equal to 0.0913 (pre-split).

    FEES AND EXPENSES

    Except as set forth below, each of General Acquisition, General Sub and GSI
will pay its own fees and expenses incurred in connection with the merger

<PAGE>
       -  prior to or at the time of the GSI special meeting, a BONA FIDE
          Acquisition Proposal is made directly to the GSI shareholders or
          otherwise becomes publicly known or a credible third party has
          announced a BONA FIDE intention to make an Acquisition Proposal, or

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

    2.  the termination of the merger agreement by General Acquisition due to
       the GSI Board's approval or recommendation of an Acquisition Proposal or
       Alternative Transaction or its approval or recommendation to GSI

       described in paragraph 9 under "Conditions to Termination" above.

    GSI is required to pay the expenses of Tyco and General Acquisition relating

General Acquisition due to GSI's willful breach of a covenant or agreement set
forth in the merger agreement, and, in addition, GSI is required to pay Tyco the
fee of $4.0 million, if

       -  prior to the termination, a BONA FIDE Acquisition Proposal is made
          directly to the GSI shareholders or otherwise becomes publicly known
          or a credible third party has announced a BONA FIDE intention to make
          an Acquisition Proposal, or

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

    GSI is required to pay to Tyco and General Acquisition their respective
expenses relating to the merger of up to $375,000 upon a termination of the
merger agreement by General Acquisition as a result of a representation or
warranty of GSI being untrue when made, as described in paragraph 6 under
"Conditions to Termination" above.

    General Acquisition is required to pay to GSI the expenses of GSI relating
to the merger of up to $375,000 upon termination of the merger agreement by GSI

Termination" above.

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

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

AMENDMENT AND WAIVER; PARTIES IN INTEREST

    The parties to the merger agreement may amend the merger agreement in
writing by action taken by or on behalf of their respective Boards of Directors
at any time prior to consummation of the merger. However, after approval of the
merger and the merger agreement by the shareholders of GSI, the merger agreement
cannot be amended without shareholder approval if shareholder approval of such
amendment is required by law.

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

    The merger agreement is binding upon and inures solely to the benefit of the
parties thereto, and nothing in the merger agreement confers upon any other
person any right, benefit or remedy of any nature whatsoever, other than certain
indemnification, employment and insurance obligations of General Acquisition and
GSI following consummation of the merger which are intended for the benefit of
certain specified officers, directors and employees of GSI and may be enforced
by such individuals and other than certain obligations of the parties to pay
certain fees and expenses.

GUARANTEE

    Tyco has fully and unconditionally guaranteed the representations,
warranties, covenants, agreements and other obligations of General Acquisition
and General Sub under the merger agreement.

          UNAUDITED PRO FORMA COMBINED CONDENSED FINANCIAL INFORMATION

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

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

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

        2. Tyco's unaudited consolidated financial statements and notes thereto
    included in its Quarterly Report on Form 10-Q for the quarterly period ended
    June 30, 1999, and

        3. GSI's audited financial statements, including the notes thereto,
    included in its Annual Report on Form 10-K for the fiscal year ended June
    30, 1999.

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

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

                    COMBINED CONDENSED FINANCIAL INFORMATION

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

(2) The unaudited pro forma combined per share amounts are based on the pro
    forma combined weighted average number of common shares which equals Tyco's
    weighted average number of common shares outstanding for the period plus the
    total number of Tyco common shares that will be delivered to GSI
    shareholders in the merger. The number of shares to be delivered in the
    merger is based on GSI shareholders receiving 0.0734 of a Tyco common share
    for each share of GSI common stock held, which assumes an average share
    price for Tyco common shares of $102.1875. The actual average share price
    may be higher or lower than this value. For purposes of the unaudited pro
    forma combined condensed financial information, 13,838,181 GSI common shares
    outstanding as of August 20, 1999 was assumed. The per share data have not
    been retroactively adjusted to reflect the two-for-one Tyco stock split
    payable on October 21, 1999.

(3) Certain reclassifications, none of which affects income from continuing
    operations, have been made to the GSI statements of operations in the
    unaudited pro forma combined condensed statements of continuing operations
    to classify research and development expenses on a consistent basis.

(4) Diluted income per common share from continuing operations for Tyco, after
    adding Liquid Yield Option Notes ("LYONs") discount amortization, was based
    on adjusted income from continuing operations available to common
    shareholders of $251.7 million for the nine months ended June 30, 1999 and
    $1,175.8 million for the fiscal year ended September 30, 1998.

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

(6) During the nine months ended June 30, 1999 Tyco recorded charges of $1.26
    billion for merger, restructuring and other non-recurring charges, of which
    $78.9 million is included in cost of sales, and $335.0 million for the
    impairment of long-lived assets primarily related to the mergers with US
    Surgical and AMP and costs associated with AMP's profit improvement plan.

(7) During the fiscal year ended September 30, 1998, Tyco recorded charges of
    $80.5 million primarily related to costs to exit certain businesses in US
    Surgical's operations and restructuring charges of $12.0 million related to
    the operations of US Surgical. In addition, Tyco recorded restructuring
    charges of $185.8 million in connection with AMP's profit improvement plan
    and a credit of $21.4 million to restructuring charges representing a
    revision of estimates related to AMP's 1996 restructuring plans.

(8) The allocation of the purchase price to the fair value of assets and
    liabilities of GSI has not yet been determined. Therefore, for purposes of
    the unaudited pro forma combined condensed financial information, the excess
    of the purchase price over the book value of net assets acquired of GSI is
    being recorded as goodwill and amortized over an estimated composite 20 year
    life to selling, general and administrative expenses.

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

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

                       CERTAIN INFORMATION CONCERNING GSI

BUSINESS OF GSI

    GENERAL

    Since its inception in April 1992, GSI has been engaged in the development,
manufacturing and marketing of balloon dissection systems and related minimally
invasive surgical instruments. GSI began commercial sales of its balloon
dissection systems for hernia repair in September 1993. To date, GSI has
received from the FDA eight 510(k) clearances for use of its technology to
perform dissection of tissue planes anywhere in the body using a broad range of
balloon sizes and shapes. GSI currently sells products in the United States,
Europe, South America and Australia for selected applications, such as hernia
repair, subfascial endoscopic perforator surgery, saphenous vein harvesting and
breast reconstruction and augmentation surgery, and laparoscopic bladder neck
suspension.

    Sales of GSI's products in the United States and internationally are
currently made through both distributors and GSI's direct sales force. To date,
the majority of the sales of GSI's products have been for use in hernia repair
procedures. While GSI has developed or is developing surgical balloon dissectors
for stress urinary incontinence, vascular and plastic surgery, sales of products
for hernia repair are expected to provide a majority of GSI's revenues at least
through fiscal year 2000.

    BALLOON DISSECTION SYSTEMS

    GSI's SPACEMAKER-Registered Trademark- tissue dissection systems, based on
the company's patented balloon technology, rapidly and gently create surgical
working spaces in the body by separating natural tissue planes without resorting
to blunt dissection used in conventional open surgery or minimally invasive
surgery conducted outside of a natural body cavity. In procedures using
SPACEMAKER-Registered Trademark- dissectors, a surgeon creates a small incision
through which the balloon is inserted and placed between naturally occurring
tissue layers such as muscle, fat, and skin. Subsequently, the balloon is filled
to a specific volume with air or saline, causing the desired dissection of the
tissue planes. The system is then deflated and removed and the dissected space
can be insufflated with gas to create a surgical operating space.

    GSI's surgical balloon dissectors incorporate several proprietary
technologies to increase the reliability, effectiveness and ease of use in
creating working spaces during minimally invasive surgery (MIS). Each balloon is
composed of strong and reliable nonelastomeric polyurethane material and is
welded using a proprietary technique that allows the balloon to be inflated to a
predetermined size and predictable shape with minimal risk of rupture. Each of
GSI's balloons is designed to be deployed in a predictable manner that maximizes
effectiveness and accuracy in creating the surgical working space and is
designed to minimize unnecessary tissue trauma because of the specific and
predictable manner in which the balloon unfurls. GSI has designed its dissection
balloons in a variety of shapes and sizes that are tailored for specific
procedures. For example, GSI's kidney shaped balloon is designed for use in
hernia repair to maximize working space and visibility of the surgical site
while minimizing the disruption of other anatomy at the surgical site.

    GSI currently offers its surgical balloon dissectors in five distinct access
and deployment platforms, the SPACEMAKER-Registered Trademark- I platform with
integral cannula, the SPACEMAKER-Registered Trademark- II platform with optimal
visualization, the SPACEMAKER-Registered Trademark- Plastics platform,
SAPHtrak-Registered Trademark- platform, and the ENDOSAPH-Registered Trademark-
platform, along with several different balloon shapes and sizes, designed for
various surgical techniques, procedures types and market segments. Each balloon
dissection system, except ENDOSAPH-Registered Trademark- system, contains three
primary components: a guide rod and blunt tip to access the surgical site; a
single use, disposable balloon dissector (which includes a tubing and valve
apparatus to fill the balloon) to create a working space at the surgical site;
and a balloon cover to protect the balloon dissector and maintain the balloon in
its furled state prior to inflation. ENDOSAPH-Registered Trademark- dissectors
contain the first two components.

                                       56
<PAGE>
The end-user price for GSI's single surgical balloon dissector is approximately
$250 per unit, and procedural kits range from approximately $350 to $850 per
kit, depending upon the type of balloon dissector platform purchased and the
ancillary instruments chosen by the customer to complete the procedural kit.

    The key attributes of GSI's five major product platforms are described
below:

    SPACEMAKER-REGISTERED TRADEMARK- I (WITH INTEGRAL CANNULA) PLATFORM.  The
SPACEMAKER-Registered Trademark- I platform is composed of a stainless steel rod
with a blunt tip which is used both as the guide rod for the balloon and as the
insertion rod for a pre-loaded integral cannula. This enables the surgeon to
insert the cannula quickly and accurately into the dissected space once the
balloon is removed. In addition, the balloon cover used with the
SPACEMAKER-Registered Trademark- I platform is a strong sheath that maximizes
its tunneling capability.

    SPACEMAKER-REGISTERED TRADEMARK- II PLATFORM.  The
SPACEMAKER-Registered Trademark- II platform is a blunt-tipped, polymeric guide
rod for insertion of the balloon. This platform is designed to allow endoscopic
visualization of the dissected space. Visualization enables the surgeon to
identify anatomical features and access the dissected surgical site. The
SPACEMAKER-Registered Trademark- II platform includes an integral balloon cover,
which releases automatically upon inflation of the balloon, thus simplifying the
procedure for the surgeon.

    SPACEMAKER-REGISTERED TRADEMARK- PLASTICS PLATFORM.  The
SPACEMAKER-Registered Trademark- Plastics platform consists of a combined
blunt-tipped guide rod and handle, used for insertion, and a balloon. An
integral cover over the balloon provides protection to the balloon during
insertion. This platform is used primarily for plastic and reconstructive breast
surgery.

    SPACEMAKER-REGISTERED TRADEMARK- SAPHTRAK-REGISTERED TRADEMARK-
PLATFORM.  The SPACEMAKER-Registered Trademark- SAPHtrak-Registered Trademark-
platform consists of a malleable steel rod with a blunt tip, an eight inch
balloon and a handle. The malleable feature of the guide rod allows the surgeon
to adjust the curvature of the device to maneuver around challenging patient
anatomy. The 150cc capacity balloon is not removable from the guide so that it
is redeployable at multiple sites along the course of the vein. This platform is
used primarily for saphenous vein harvesting.

    ENDOSAPH-REGISTERED TRADEMARK- PLATFORM.  The
SPACEMAKER-Registered Trademark- ENDOSAPH-Registered Trademark- platform
consists of two disposable devices: the SAPHfinder-TM- balloon dissector and the
SPACEKEEPER-TM- retractor. The SAPHfinder-TM- balloon dissector consists of an
open-ended tip on a hollow guide rod, an eight inch balloon, and a handle. The
device is designed to accommodate a standard-length 5mm endoscope for viewing
from the tip. The 150cc capacity balloon is not removable from the guide rod so
that it is re-deployable at multiple sites along the course of the vein. The
SPACEKEEPER-TM- retractor is a single-piece, polycarbonate construction
consisting of a distal retractor, 5mm endoscope channel and handle. The
retractor is used to hold the operating space open after removal of the balloon
and is also designed to accommodate a standard-length 5mm endoscope. This
platform is used primarily for saphenous vein harvesting.

    APPLICATIONS OF BALLOON DISSECTION TECHNOLOGIES

    GSI's initial market focus has been the application of its
SPACEMAKER-Registered Trademark- balloon dissection technology for hernia
repair. More recently, GSI has begun to increase its emphasis on
cardiac/vascular applications. GSI has completed marketing-related clinical
studies of, and has introduced products for, saphenous vein harvesting,
subfascial endoscopic perforator surgery, breast augmentation and reconstruction
procedures, stress urinary incontinence applications. GSI believes that its
current FDA clearances provide coverage for many surgical applications that it
may pursue. GSI has commenced commercial sales of its products in the United
States, Europe, Asia and South America for selected applications including
hernia repair, saphenous vein harvesting, SEPS and breast augmentation and
reconstruction surgery.

    HERNIA REPAIR

    A hernia, a condition that commonly occurs in the groin, is a protrusion of
normal abdominal contents through a muscle defect, usually in the tissue layers
overlying the abdomen. The peritoneum and/or bowel often project into this
defect, causing pain and potential major complications. In 1997 over 650,000
people in the United States and approximately 1.3 million people worldwide
underwent surgery for hernia repair.

    The open surgical procedure for hernia repair is a herniorrhaphy, which
involves making a 10 to 15 cm open incision in the groin over the muscle defect
to be repaired. As in most invasive surgical procedures, recovery periods tend
to be long, typically extending between three and six weeks.

    Over the last few years, in an effort to reduce post-operative pain and
recovery times, several laparoscopic techniques have been developed to repair
hernias. Despite these advances, there is not yet a consensus on the optimal
method for MIS hernia repair. For example, in certain MIS hernia repair
procedures, a surgeon first makes an incision in the abdominal wall to gain
access to the abdominal cavity. She then makes an additional incision in the
peritoneum in order to reach the surgical site and create the working space
required to conduct the surgical repair. GSI believes that its balloon
dissection technology can significantly improve the outcome of this laparoscopic
hernia repair procedure by eliminating the need for an incision in the abdominal
wall.

    Utilizing GSI's SPACEMAKER-Registered Trademark- products, the surgeon
tunnels the device through a small incision at the umbilicus and then inflates
the balloon to create a large and relatively bloodless space at the site of the
hernia, but outside the abdominal wall. As a result, the surgeon is able to
access the target surgical site and complete the hernia repair. In addition,
because the surgeon never enters the peritoneum, this procedure reduces the risk
of organ damage, adhesion formation and morbidity, and eliminates the
requirement for general anesthesia. In a study published in March 1997 by the
NEW ENGLAND JOURNAL OF MEDICINE, MIS hernia repair procedures utilizing balloon
dissection systems resulted in fewer recurrences and faster recovery times as
compared to traditional open surgical hernia repair procedures.

    GSI believes that its SPACEMAKER-Registered Trademark- products provide a
platform for increasing the conversion of open hernia repair procedures to
laparoscopic procedures. According to Medical Data International, Inc.,
laparoscopic hernia repair procedures represented approximately 104,000 or 16
percent of total hernia repair procedures in the United States in 1997.

    GSI commenced commercial sales of its hernia repair balloon dissection
products in the United States in late 1993 and in Europe in 1994 and currently
sells two versions: the SPACEMAKER-Registered Trademark- I platform, which was
introduced in September 1993 and the SPACEMAKER-Registered Trademark- II
platform, which was introduced in October 1995. GSI sells these products both in
the United States and certain foreign markets, including Europe, Australia and
South America, through its direct sales force and distributors.

    SUBFASCIAL ENDOSCOPIC PERFORATOR SURGERY

    Chronic venous insufficiency, which results in insufficient blood flow from
the extremities, is a common and debilitating disease. A frequent manifestation
of venous insufficiency is venous stasis ulceration (chronic skin ulcers), which
currently affects approximately 1.25 million people in the United States.

    GSI believes that current treatment options for venous stasis ulceration and
venous insufficiency are suboptimal. Compression stockings (elastic stockings
that put pressure on the leg to force blood flow), the most common treatment,
often temporarily heal the ulcers but do not treat the underlying venous
incompetence. Compression stockings as treatments are also ineffective because
patients often do not wear the stockings, the associated healing process is slow
and the recurrence rate for the ulcers is high. Treating the incompetent vein
through an open surgical procedure allows treatment of the underlying condition,
but requires an incision through the ulcer wound, which is composed of diseased

                                       58
<PAGE>
tissue and is often incapable of healing. Alternatively, a minimally invasive
ligation procedure known as subfascial endoscopic perforator surgery (SEPS)
allows the surgeon to access the incompetent vein from an incision remote from
the ulcer wound using traditional dissection instruments. However, because this
access to the surgical site causes bleeding and significant tissue trauma, the
procedure is difficult and time consuming for the surgeon to perform because of
poor visualization

    GSI's SPACEMAKER-Registered Trademark- surgical balloon dissectors allow the
surgeon to perform SEPS to ligate incompetent veins endoscopically in a
relatively atraumatic, bloodless manner. By utilizing GSI's
SPACEMAKER-Registered Trademark- technology, the surgeon is able to deploy an
elongated balloon down the length of the patient's leg to create an operating
space for access to one or more incompetent veins. Because the incisions needed
for this procedure are very small (approximately one cm) and are remote from the
area of ulcerated skin, GSI believes that wounds will heal more rapidly and that
there will be fewer complications compared to open surgery at or near the ulcer
site. In addition, the relatively bloodless working space created by GSI's
balloon provides the surgeon with improved visualization of the veins requiring
ligation, making the procedure easier and faster for the surgeon.

    GSI launched its initial product to treat venous stasis ulceration and
venous insufficiency in January 1996. Additional outcome studies have been
completed, including the study reported in the June 1997 JOURNAL OF VASCULAR
SURGERY that supported GSI's belief that balloon assisted SEPS tends to produce
faster healing rates, fewer complications and lower recurrence rates as compared
to compression stockings or open surgical ligation. By the end of 1998, GSI's
SPACEMAKER-Registered Trademark- I balloon dissection products had been used to
treat over 1,100 patients suffering from venous stasis ulcers or venous
insufficiency in over 250 centers across the United States, with results
indicating generally successful outcomes.

    SAPHENOUS VEIN HARVESTING

    In recent years, advanced coronary artery disease has been increasingly
treated by coronary artery bypass graft (CABG) procedures, which usually involve
grafting a portion of a patient's vein, taken from a different part of the body,
around an arterial blockage. An estimated 665,000 CABG procedures were performed
worldwide in 1998. About 80 percent of these procedures in the United States
utilize the patient's saphenous vein for bypass grafting.

    Traditional saphenous vein harvesting procedures require a continuous
incision above the vein segment to be harvested, often from the ankle to the
upper thigh of the patient's leg. The saphenous vein is then dissected and
removed, and the wound is sutured closed. A study published in the Annals of
Thoracic Surgery in 1998 involving over 112 patients indicates that the open
surgical procedure for saphenous vein harvesting results in wound healing
impairment in approximately 19 percent of patients. The length and invasiveness
of the leg incision also causes significant postoperative patient pain and
discomfort. Surgeons indicate that after the CABG procedure patients more
frequently complain about the pain caused by leg incisions than other aspects of
the procedure.

    GSI launched its ENDOSAPH-Registered Trademark- vein harvest system,
utilizing balloon dissection technology and ancillary instruments in January
1998. By utilizing GSI's ENDOSAPH-Registered Trademark- balloon dissection
system and hook and fork dissection tools in the saphenous vein harvest
procedure, the surgeon can reduce the leg incisions to a total length of three
or four centimeters, and can minimize damage to the muscles and nerve endings
surrounding the saphenous vein. Results from clinical usage of the
ENDOSAPH-Registered Trademark- vein harvest system indicate generally successful
outcomes from the procedure including less postoperative pain, faster healing
and less scarring than with traditional open procedures.

    STRESS URINARY INCONTINENCE SURGERY

    Stress urinary incontinence (SUI) is the uncontrollable loss of urine due to
a displacement of the bladder neck. THE JOURNAL OF UROLOGY in September 1997
reported the findings of The American Urological Association Female Stress
Urinary Incontinence Clinical Guidelines Panel which concluded

                                       59
<PAGE>
from long-term outcomes that "surgical treatment of stress urinary incontinence
effective, offering a long-term cure in a significant percentage of women."

    Depending on the severity of incontinence, there are a number of treatment
options for SUI, including collagen injections, drugs, biofeedback exercises and
absorbent pads. The standard treatment for severe SUI is a highly invasive, open
surgical procedure involving suture suspension of the bladder neck. This method
can create significant complications for the patient, including enterocele (a
hernia within the vaginal wall) and genital prolapse (a descending of the uterus
due to a weakness of the pelvic floor). Furthermore, after surgery patients may
require up to six weeks or more to resume their preoperative lifestyle. Because
of the risk, expense and complexity of open suture suspension, this surgical
procedure is often performed only in conjunction with other open abdominal
procedures such as hysterectomy.

    Several MIS alternatives to open surgical procedures for the treatment of
SUI have recently been developed to suspend the bladder neck. These less
invasive procedures have been increasingly accepted as stand-alone procedures
and are typically less expensive and less likely to cause adverse side effects.
Outcome studies are now becoming available which indicate satisfactory outcomes
for MIS procedures when compared to open bladder neck suspension procedures in
successfully treating incontinence. As in hernia repair, some MIS techniques
involve accessing the surgical site by entering, traversing and then exiting the
abdominal cavity. While these procedures offer improvements over open surgery
and afford the benefits of MIS, they still involve the morbidity risks and
difficulties associated with violating the peritoneum.

    Utilizing GSI's surgical balloon dissector, the surgeon can suspend the
bladder neck laparoscopically without entering the peritoneum, and can do so
under visualization. As in the hernia repair procedure, GSI's
SPACEMAKER-Registered Trademark- dissection products can be deployed near the
umbilicus to provide direct access to the bladder and bladder neck. The surgeon
can then use conventional laparoscopic instruments to complete the procedure. A
study published in THE JOURNAL OF THE AMERICAN ASSOCIATION OF GYNECOLOGIC
LAPAROSCOPISTS in November 1996 shows that the SUI repair procedure utilizing
balloon dissection can usually be performed in less than one hour on an
outpatient basis.

    GSI offers a SPACEMAKER-Registered Trademark- II dissector and
SPACEMAKER-Registered Trademark- Total Solution-TM- Laparoscopic Bladder Neck
Suspension kit to specifically to address the extraperitoneal treatment of SUI,
which GSI believes optimizes the working space for the procedure.

    BREAST AUGMENTATION AND RECONSTRUCTIVE SURGERY

    In 1997, approximately 150,000 women in the United States had breast
reconstruction and augmentation surgery. Traditional surgical methods for such
procedures require making a three to five cm incision in the skin, finding the
required tissue plane, and then using a combination of blunt and sharp
dissection tools to create a pocket for the implant. The procedure can cause
substantial bleeding, can sever both sensory nerves and perforating vessels and
can leave the patient with substantial, noticeable scars.

    In contrast to traditional breast augmentation and reconstruction
procedures, GSI's SPACEMAKER-Registered Trademark- products require only small
incisions, create a relatively bloodless pocket, minimize disruption of sensory
nerves and perforating vessels and minimize scarring and loss of mobility or
sensation. In addition, because the SPACEMAKER-Registered Trademark- product
allows the surgeon to introduce the balloon dissector from a crease in the
axilla (armpit), from the inframammary fold (below the breast), or in the
periareolar (nipple) area, the surgeon can minimize the appearance of any marks
or scars. GSI believes that its SPACEMAKER-Registered Trademark- dissection
products for breast augmentation and reconstruction procedures enable the
surgeon to create uniform, symmetrical pockets in less time and with much less
bleeding than is possible with traditional blunt or sharp dissection tools.

                                       60
<PAGE>
    GSI's balloon dissection products for breast augmentation and reconstruction
were first introduced commercially in the United States in January 1995. The
SPACEMAKER-Registered Trademark- Plastic platform is used for these procedures.

    OTHER COSMETIC AND RECONSTRUCTIVE SURGERY

    In addition to the market opportunities for breast augmentation and
reconstruction, GSI has designed and developed balloon dissection technology for
combined tissue dissection and expansion for general cosmetic and reconstructive
surgery procedures. Gsi believes that its balloon dissection technology is
well-suited for such procedures, including limb reconstruction, correction of
congenital deformities and scar revision.

    SPINE SURGERY

    GSI believes that its products can be used to provide exposure in several
orthopedic spinal procedures to both reduce the costs of the procedure and
enhance patient benefits. Foremost among these procedures is spinal fusion,
which was performed approximately 200,000 times in the United States in 1994.
Spinal fusion is usually performed to remove a ruptured vertebral disc that is
causing significant patient discomfort, and subsequently to promote fusion
between the then exposed and adjacent vertebrae. This fusion procedure can be
performed by using any of several prosthetic systems, by traditional bone
prostheses, or by a combination of the two.

    Most traditional open spinal fusion procedures have approached the spine
from the back. Several newer procedures, some currently under clinical
investigation, approach the spine through the abdomen, which appears to yield
better results. The open abdominal approach is highly invasive, however, and has
led researchers to try to develop a minimally invasive, transperitoneal
laparoscopic approach. This approach still subjects the patient to the same
risks associated with the open abdominal approach. GSI's surgical balloon
dissectors have been used in several cadaver studies in which an extraperitoneal
laparoscopic approach to the spine has been successfully performed. In this
procedure, the balloon is deployed in the retroperitoneal area under the rib
cage and is inflated in order to dissect the peritoneum away from muscle layers
in the back and side of the patient. By doing so, the surgeon can create a large
working space to access the spine without entering the peritoneum. GSI believes
the spinal fusion procedure is a natural extension of the aortic reconstruction
application for balloon dissection technology because the required dissected
space is essentially the same. GSI intends to conduct additional
marketing-related clinical evaluations to evaluate physician preference and
utility of its SPACEMAKER-Registered Trademark- surgical balloon dissectors for
the orthopedic spine surgery market.

    ADDITIONAL PRODUCTS UNDER DEVELOPMENT

    As part of its competitive strategy, GSI continually seeks to leverage its
core technology to develop surgical balloon dissectors for new surgical
procedures, as well as to develop new surgical instruments for MIS. GSI has made
a significant investment in developing its proprietary balloon dissection
technology and believes its research and development commitment in this area is
critical to its competitive position. Research and development expenses for
fiscal 1999, 1998 and 1997 were approximately $3.7 million, $2.8 million and
$2.2 million, respectively. As of June 30, 1999, GSI employed 14 persons engaged
in research and development activities.

    GSI is continuing to exploit its expertise in MIS to develop a range of
instruments to maximize the surgeon's ability to perform MIS once an operative
working space is created by its surgical balloon dissectors. Product research
and development will require substantial expenditures, and there can be no
assurance that GSI will be successful in identifying products for which demand
exists, in developing products that have the characteristics necessary to treat
target indications, or that any new product introduced will receive regulatory
approval or be commercially successful.

    YEARS ENDED JUNE 30, 1999 AND 1998

    REVENUE.  Revenue totaled $6.9 million in fiscal 1999, an increase of $0.1
million or one percent over revenue of $6.8 million in fiscal 1998. During
fiscal 1999, no guaranteed payments were received from Ethicon Endo-Surgery
(EES), a distributor of GSI's products in the United States, versus $1.6 million
during fiscal 1998. Product sales accounted for all of the fiscal 1999 revenue,
which represents a 32 percent increase over fiscal 1998 product sales. The
increase in product sales is due to an increase in product demand, primarily for
SPACEMAKER-Registered Trademark- Total Solution-TM- hernia kits, as well as
expanded product distribution in the fourth quarter.

    COST OF SALES.  Cost of sales at $5.2 million in 1999 increased 46% as
compared to $3.6 million in 1998 due to increased product sales and production
capacity ramp-up. Direct product costs were 76 percent of total product sales in
fiscal 1999, an increase of seven percent from fiscal 1998, as a result of
increasing costs related to ramping up production capacity in anticipation of
the court injunction against Origin Medsystems, Inc. In addition, GSI's product
costs have increased relative to sales dollars as additional OEM products are
offered as part of the SPACEMAKER-Registered Trademark- Total Solution-TM-
hernia and laparoscopic bladder neck suspension kits. GSI expects cost of sales
as a percentage of product sales to decrease as GSI's sales volume increases.

    RESEARCH AND DEVELOPMENT EXPENSES.  Research and Development (R&D) expenses
for fiscal 1999 increased 31 percent to $3.7 million versus $2.8 million for the
year ended June 30, 1998. Increases over the prior year are mainly due to
increased expenditures on new general surgery product design work in conjunction
with expanding SPACEMAKER-Registered Trademark- Total Solution-TM- hernia and
laparoscopic bladder neck suspension kit offerings, as well as an increase in
the number of employees in R&D. GSI expects to continue to increase R&D expenses
as it pursues additional market opportunities.

    SELLING, GENERAL AND ADMINISTRATIVE EXPENSES.  Selling, General and
Administrative (SG&A) expenses were $15.6 million in fiscal year 1999, an
increase of 32 percent as compared to $11.8 million in fiscal 1998. This
increase is primarily related to litigation expenses related to the Origin
matters and are expected to decrease in the future. In addition, sales and
marketing expenses increased as GSI devoted more resources to physician training
programs as well as increased exposure at relevant industry trade shows. GSI
expects increases in SG&A expenses as GSI's level of sales increases and GSI
continues to administratively support growth, and expects SG&A to be impacted by
its ongoing litigation matters.

    INTEREST AND OTHER INCOME AND EXPENSE (NET).  Interest and other income and
expense (net) totaled $1.5 million in fiscal 1999 compared to $2.3 million in
fiscal 1998, and consisted mainly of interest income, primarily from interest
earned on available-for-sale securities. Interest income decreased 32% from $2.3
million in 1998 to $1.6 million in 1999, due to overall lower cash balances in
connection with funding ongoing operating activities.

    NET LOSS.  GSI had a net loss of approximately $16.1 million in fiscal 1999
compared to a $9.1 million net loss in fiscal 1998, primarily due to the
increased operating expenses as GSI prepared for anticipated sales growth and
aggressively defended its patent positions.

    YEARS ENDED JUNE 30, 1998 AND 1997

    SALES AND GUARANTEED PAYMENTS.  Sales and guaranteed payments totaled $6.8
million in fiscal 1998, a decrease of $2.2 million or 24 percent from sales and
guaranteed payments of $9.0 million in fiscal 1997. This decrease in revenue is
in connection with the conversion of EES to a non-exclusive distributor, which
eliminated future guaranteed payments. During fiscal 1998, $1.6 million in
guaranteed payments was received from EES versus $4.9 million during fiscal
1997. Product sales accounted for $5.2 million of total revenue in fiscal 1998,
which represents a 27 percent increase over fiscal 1997. This increase was a
result of rapid growth in sales of GSI's vascular surgery products and plastic
surgery products.

                                       63
<PAGE>
    COST OF SALES.  Direct product costs were 69 percent of total product sales
in fiscal 1998, an increase of 11 percent from fiscal 1997, as a result of
underutilized manufacturing capacity in fiscal 1998.

    RESEARCH AND DEVELOPMENT EXPENSES.  R&D expenses for fiscal 1998 increased
27 percent to $2.8 million versus $2.2 million for the year ended June 30, 1997,
as GSI continued to develop products for its vascular and hernia markets. GSI
expects to continue to increase R&D expenses as it pursues additional market
opportunities.

    SELLING, GENERAL AND ADMINISTRATIVE EXPENSES.  SG&A expenses were $11.8
million in fiscal year 1998, an increase of 35 percent as compared to $8.8
million in fiscal 1997. This increase is primarily related to increased
litigation expenses related to the Origin infringement case.

    INTEREST AND OTHER INCOME AND EXPENSE (NET).  Interest and other income and
expense (net) totaled $2.3 million in fiscal 1998 compared to $2.5 million in
fiscal 1997, and consisted mainly of interest income, primarily from interest
earned on available-for-sale securities. Interest income decreased 10% from $2.6
million in 1997 to $2.3 million in 1998, due to overall lower cash balances in
connection with funding ongoing operating activities.

    NET LOSS.  GSI had a net loss of approximately $9.1 million in fiscal 1998
compared to a $1.9 million net loss in fiscal 1997, primarily due to the
decrease in guaranteed payments from EES and increased operating expenses as GSI
prepared for anticipated sales growth and aggressively defended its patent
position.

    LIQUIDITY AND CAPITAL RESOURCES

    Since inception, GSI's cash expenditures have significantly exceeded its
sales, resulting in an accumulated deficit of $40.9 million at June 30, 1999.
GSI has funded its operations primarily through the sale of equity securities.
From its inception through June 30, 1999, GSI raised approximately $15.5 million
through the private placement of equity securities, and approximately $46.9
million (net of underwriting discounts and commissions) in an initial public
offering.

    Net cash used in operating activities in 1999 was approximately $16.1
million which consisted mainly of GSI's net loss for the year of $16.1 million
offset slightly by increases in gross accounts receivable and inventory of $3.3
million. Net cash provided by investing activities totaled approximately $8.0
million. Proceeds from sales and maturities of available-for-sale securities of
$13.5 million was somewhat offset by purchases of available-for-sale securities
of $3.8 million and acquisition of property and equipment of $1.7 million. Net
cash used in financing activities was approximately $258,000, which consisted of
$157,000 in proceeds from the issuance of common stock, offset by a $300,000
outflow for a related party loan, as well as $117,000 in payments on capital
lease obligations and bank borrowings.

    As of June 30, 1999, GSI's principal source of liquidity consists of cash,
cash equivalents and investments of $19.3 million. GSI has an equipment loan
outstanding with a balance of approximately $82,000. GSI expects to spend
approximately $2.1 million on capital equipment purchases in fiscal year 2000.

    GSI expects to incur additional costs over the next fiscal year, including
costs related to increased sales and marketing activities, increased research
and development, additional marketing-related clinical studies, and litigation
costs. GSI believes that its current cash balances and short-term investments
along with cash generated from the future sales of products will be sufficient
to meet GSI's operating and capital requirements through calendar year 2000. GSI
may seek additional equity or debt financing to address its working capital
needs or to provide funding for capital expenditures. There can be no assurance
that additional financing, if sought, will be available on satisfactory terms or
at all.

    MANAGEMENT INFORMATION SYSTEMS

    The Year 2000 ("Y2K") issue arises from computer programs using two digits
rather than four to define the applicable year. Such software may recognize a
date using "00" as the year 1900 rather than the year 2000. This could result in
system failures or miscalculations leading to disruptions or delays in GSI's
activities and operations. If GSI, its key customers or suppliers fail to make
necessary modifications to their information technology or non-information
technology systems on a timely basis, the year Y2K issue could have a material
adverse effect on GSI's operations. However, the impact cannot be quantified at
this time.

    In January 1998 GSI began to evaluate and assess its information technology
and non-information technology systems for compliance with the Y2K issue. GSI
intends to fix or replace noncompliant software and systems by November 30,
1999, but there can be no assurance that such fixes or replacements will occur
by such date. GSI is currently conducting testing and remediation activities on
its systems, and intends to survey major customers and suppliers to assess their
systems' compliance as well as their systems' compatibility with GSI's existing
or projected compliant systems. There can be no assurance that there will not be
an adverse material effect on GSI's business, financial condition or results of
operations if GSI or its suppliers or customers do not convert or replace their
systems in a timely manner to comply with the Y2K issue.

    GSI's costs related to the Y2K issue are funded through operating cash
flows. Through fiscal 1999, GSI expended approximately $20,000 in evaluating and
planning and fixing and replacing noncompliant systems, including the cost of
new software and modifying the applicable code of existing software. GSI
estimates total costs to be approximately $25,000 to achieve Y2K compliance. GSI
currently believes that the total cost of achieving Y2K compliant systems will
not be material to its business, financial condition or results of operations.
In the event that GSI will be unable to achieve Y2K compliance in a timely
manner with existing personnel, as a contingency GSI expects to hire outside Y2K
solution providers to assist in achieving such compliance. GSI has not yet
developed a complete contingency plan for dealing with the most likely
worst-case scenario, as this scenario has not yet been clearly identified. GSI
currently plans to complete such contingency planning by November 30, 1999.
There can be no assurance that such contingency plan will adequately address
GSI's Y2K compliance issues.

    Time and cost estimates are based on currently available information.
Factors that could affect these estimates include, but are not limited to, the
availability and cost of trained personnel to evaluate and implement the
changes, the ability to locate and correct all noncompliant systems, and the
ability of GSI's customers and suppliers to successfully implement Y2K compliant
systems or fixes.

    RECENT ACCOUNTING PRONOUNCEMENTS

    In June 1998, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 133 ("SFAS 133"), "Accounting for Derivative
Instruments and Hedging Activities," which establishes accounting and reporting
standards for derivative instruments and hedging activities. It requires that an
entity recognize all derivatives as either assets or liabilities in the
statement of financial position and measure those instruments at fair value. To
date, GSI has not engaged in derivative and hedging activities. SFAS 133 will be
effective for fiscal years beginning after June 15, 2000.

    QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

    Market risk represents the risk of loss that may impact GSI's financial
position, operating results or cash flows due to changes in financial and
commodity market prices and rates. GSI's exposure to market risk for changes in
United States interest rates relates primarily to its investment portfolio and
bank borrowings. GSI does not use derivative financial instruments in its
investment portfolio, and its investment portfolio only includes highly liquid
instruments with original maturity dates ranging

                                       65
<PAGE>
between September 24, 1999 and October 30, 2000. GSI has primarily entered into
debt obligations for capital expenditures.

    GSI is subject to fluctuating interest rates that may impact, adversely or
otherwise, its results of operations or cash flows for our variable rate bank
borrowings, available-for-sale securities and cash and cash equivalents.

interest rates by period of maturity for our investment portfolio and debt

    FACTORS AFFECTING FUTURE RESULTS

    The following discussion should be read in conjunction with the consolidated
financial statements and notes thereto included herein.

    GSI desires to take advantage of the "safe harbor" provisions of the Private
Securities Litigation Reform Act of 1995. Specifically GSI wishes to alert
readers that, except for the historical information contained in this
Management's Discussion and Analysis of Financial Condition and Results of
Operations, the matters discussed herein are forward-looking statements that are
subject to certain risks and uncertainties that could cause the actual results
to differ materially from those projected. Factors that could cause actual
results to differ materially include, but are not limited to, outcomes in
litigation proceedings, market demand for GSI's products, the timing of orders
and shipments, the timely development and market acceptance of new products and
surgical procedures, the impact of performance of GSI's distributors and direct
sales force, GSI's ability to further expand into international markets, public
policy relating to health care reform in the United States and other countries,
approval of its products by government agencies such as the United States Food
and Drug Administration, and other risks detailed below and included from time
to time in GSI's other SEC reports and press releases, copies of which are
available from GSI upon request. GSI assumes no obligation to update any
forward-looking statements contained herein. The factors listed under "Factors
Affecting Future Results," as well as other factors, have in the past affected,
and could in the future affect, GSI's actual results and could cause GSI's
results for future periods to differ materially from those expressed in any
forward-looking statements contained in the following discussion.

    HISTORY OF LOSSES AND ANTICIPATED FUTURE LOSSES.  GSI has experienced
significant operating losses since inception. As of June 30, 1999, GSI had an
accumulated deficit of $40.9 million. GSI's net operating losses for the fiscal
years ending June 30, 1999, 1998 and 1997 were $16.1 million, $9.1 million and
$1.9 million, respectively. GSI expects to continue to incur operating losses on
a quarterly and annual basis through at least fiscal 2000. There can be no
assurance that GSI will ever generate substantial revenue or achieve
profitability. Failure by GSI to generate substantial revenues

                                       66
<PAGE>
would have material adverse effect on the Company's business, financial
conditions and results of operations.

    DEPENDENCE UPON BALLOON DISSECTION PRODUCTS; RISK OF TECHNOLOGICAL
OBSOLESCENCE.  Nearly all of GSI's sales since inception have been derived from
sales of its balloon dissection products, with a substantial portion derived
from sales for hernia repair procedures. The success of GSI's products depends
on the market acceptance of and demand for GSI's products and related
procedures, the nature of the technological advances inherent in the product
designs, reduction in patient trauma or other benefits provided by such
products, continued adoption of minimally invasive surgery (MIS) procedures by
surgeons, reimbursement for GSI's products by health care payors and GSI's
receipt of regulatory approvals. There can be no assurance that GSI's products
will have the required technical characteristics, that GSI's products will
provide adequate patient benefits, that clinical studies results will be
favorable, that surgeons will continue to adopt MIS procedures, that
recently-introduced products or future products of GSI or procedures using GSI's
products will gain market acceptance, or that required regulatory approvals will
be obtained. The failure to achieve any of the foregoing could have a material
adverse effect on GSI's business, financial condition and results of operations.
To the extent demand for GSI's surgical balloon dissectors for hernia repair
declines and GSI's newly-introduced products are not commercially accepted or
its existing products are not developed for new procedures, there could be a
material adverse effect on GSI's business, financial condition and results of
operations. See "Business of GSI--Applications of Balloon Dissection Technology"
and "--Additional Products Under Development."

    DEPENDENCE ON KEY DISTRIBUTORS.  In February 1998, GSI entered into a
non-exclusive distribution agreement with EES. Unlike the prior EES OEM
agreement, this new agreement does not provide for any minimum payments from EES
to GSI. In December 1997, GSI entered into a distribution agreement with
Genzyme. Under the agreement, Genzyme has exclusive rights to market and
distribute GSI's surgical balloon dissectors worldwide for use in plastic
surgery (reconstructive and aesthetic) procedures. In September 1998, GSI signed
a non-exclusive, three-year agreement with USSC, a wholly-owned subsidiary of
Tyco. Under the terms of the agreement, USSC has obtained non-exclusive rights
to market and distribute GSI's SPACEMAKER-Registered Trademark- surgical balloon
dissectors worldwide for use in hernia repair and incontinence procedures.

    In May 1999, GSI signed a distribution agreement with Dexterity Surgical,
Inc. The terms of the agreement give Dexterity rights to market and distribute
GSI's SPACEMAKER-Registered Trademark- balloon dissector products for hernia
repair and laparoscopic bladder neck suspension repair procedures in all or
parts of 28 states.

    In June 1997, GSI entered into an exclusive agreement with Japan Lifeline to
market and distribute in Japan GSI's surgical balloon dissectors for use in
vascular procedures. Distribution of the GSI surgical balloon dissectors is
expected to begin following final receipt of the Japanese Ministry of Health and
Welfare approval, which GSI expects to occur in fiscal year 2000.

    Although GSI intends to continue to establish additional distributorships in
the United States and internationally, there can be no assurance that its
distributors will be successful, or that efforts to establish additional
distributors will be successful. Failure of current distributors to succeed, or
failure to add additional distributors to its distribution network, could have a
material adverse effect on GSI's business, financial condition and results of
operations.

    LIMITED MARKETING AND DIRECT SALES EXPERIENCE.  GSI has only limited
experience marketing and selling its products through its direct sales force.
GSI intends to establish relationships with additional distribution partners,
and there can be no assurance that GSI will be successful in establishing such
relationships on commercially reasonable terms, if at all. The failure to
establish and maintain an effective distribution channel for GSI's products, or
to hire and retain qualified and effective direct

                                       67
<PAGE>
sales personnel to support commercial sales of GSI's products, could have a
material adverse effect on GSI's business, financial condition and results of
operations.

    UNCERTAINTY OF MARKET ACCEPTANCE; NO ASSURANCE OF CLINICAL ADVANTAGE.  GSI's
success is substantially dependent upon the success of its
SPACEMAKER-Registered Trademark- balloon dissection products. GSI believes that
market acceptance of GSI's products will depend on the adoption of laparoscopic
techniques generally and the conversion of non-balloon dissection techniques to
balloon dissection techniques specifically. To date, GSI has limited long-term
outcomes data regarding successful balloon dissection procedures. If GSI is not
able to demonstrate consistent clinical benefits resulting from the use of its
products (including reduced procedure time, reduced patient trauma and lower
costs) or to the extent that laparoscopic techniques are adopted slowly, that
surgical balloon dissectors are not incorporated into laparoscopic techniques or
that surgeons are unwilling or unable to develop the skills necessary to utilize
surgical balloon dissectors, GSI's business, financial condition and results of
operations could be materially adversely affected.

    GSI further believes that the ability of health care providers to obtain
adequate reimbursement for procedures using GSI's
SPACEMAKER-Registered Trademark- balloon dissection products and related
instruments will be critical to market acceptance of GSI's products. Although
GSI believes that procedures using its balloon dissection products currently may
be reimbursed in the United States under certain existing procedure codes, there
can be no assurance that such procedure codes will remain available or that
reimbursement under these codes will be adequate. The failure to obtain
reimbursement for some or all of its products could have a material adverse
effect on GSI's business, financial condition and results of operations.

    FLUCTUATIONS IN QUARTERLY RESULTS.  Results of GSI's operations may
fluctuate significantly from quarter to quarter and will depend on numerous
factors, including (i) fluctuations in purchases of GSI's products by its
distributors and direct sales force, (ii) the ability of GSI's distributors to
effectively promote and sell GSI's products, (iii) the rate of adoption by
surgeons of balloon dissection technology in markets targeted by GSI , (iv) the
mix of sales among distributors and GSI's direct sales force, (v) new product
introductions by GSI and its competitors, (vi) fluctuations in revenues among
different product lines and markets, (vii) timing of patent and regulatory
approvals, if any, (viii) litigation, (ix) timing and growth of operating
expenses and (x) general market conditions.

    In addition, announcements or expected announcements by GSI, its competitors
or its distributors of new products, new technologies or pricing changes could
cause existing or potential customers of GSI to defer purchases of GSI's
existing products and could alter the mix of products purchased from GSI, which
could have a material adverse effect on GSI's business, financial condition and
results of operations. There can be no assurance that future products or product
enhancements will be successfully introduced or that such introductions will not
adversely affect the demand for existing products. As a result of these and
other factors, GSI's quarterly operating results have fluctuated in the past,
and GSI expects that such results may fluctuate in the future. Due to such
quarterly fluctuations in operating results, quarter-to-quarter comparisons of
GSI's operating results are not necessarily meaningful and should not be relied
upon as indicators of likely future performance or annual operating results.
GSI's limited operating history makes accurate prediction of future operating
results difficult or impossible to make. There can be no assurance that in the
future GSI will achieve sales growth or become profitable on a quarterly or
annual basis, if at all, or that its growth, if any, will be consistent with
predictions by securities analysts and investors. In such event, the price of
GSI's common stock would likely be materially and adversely affected.

    RELIANCE ON PATENTS AND PROPRIETARY TECHNOLOGY.  GSI's success will depend
on its ability to obtain patent protection for its products and processes, to
preserve its trade secrets and proprietary technology and to operate without
infringing upon the patents or proprietary rights of third parties.

                                       68
<PAGE>
    In May 1996, Origin Medsystems, Inc., a unit of Guidant Corporation filed
suit against GSI for infringement of U.S. Patent No. 5,520,609 in the United
States District Court for the Northern District of California (C96-20424JW). In
April 1998, GSI had obtained a summary judgment that the patent in suit, Moll et
al Patent No. 5,520,609, was unenforceable because it had been obtained by
misleading the Patent & Trademark Office, and an award of attorney's fees of
$990,000. The appellate court subsequently vacated this decision because, in its
view, there are factual issues which must be resolved in a trial on whether
Origin misled the PTO. In July 1999, the case was returned to the district court
for further proceedings.

    In June 1996, GSI filed an action against Origin in the U.S. District Court
for the Northern District of California alleging that the use of Origin's
products infringes GSI's U.S. Patent No. 5,514,153 (C96-20447JW). The case was
decided in favor of GSI partly by summary judgment and partly by jury verdict,
both during fiscal 1999. Patent 5,514,153 ("the '153 patent") was found to be
valid, and Origin's infringement was found to be willful. Lost profits of
approximately $12.9 million were awarded to GSI by the jury. Origin is appealing
the infringement and willfulness findings (but not patent validity nor the
amount of infringement damages), and GSI is appealing for enhanced damages,
attorneys' fees and the failure to find infringement of additional claims.
Resolution is expected in calendar year 2000. Following these findings, the
Court has entered an injunction prohibiting sale in the United States of all of
Origin's balloon dissection products, to become fully effective on November 15,
1999, and an immediate injunction against sales of all of Origin's balloon
dissection products to any new customers in the United States.

    In September 1997, GSI filed an action against Origin alleging that the use
of Origin's products infringes GSI's U.S. Patent No. 5,667,520 (C97-20944JW).
Discovery is nearly complete in this case and the complaint has now been amended
to add a claim of infringement of GSI's patent number 5,860,997. This case is
now stayed pending the outcome of appeals in the '153 case.

    GSI is also involved in an interference proceeding in the U.S. Patent Office
against Origin to determine whether certain subject matter was first invented by
GSI and whether the disputed matter is patentable. In November 1998, binding
arbitration determined that GSI was first to invent the disputed subject matter
and therefore is the only party entitled to any patent. Additionally, the Patent
Office Appeals Board found the subject matter to be patentable. This latter
finding is being appealed by Origin to the Court of Appeals for the Federal
Circuit. Resolution is expected in calendar year 2000.

    On April 9, 1999, a suit was filed against GSI in the United States District
Court for the Southern District of Illinois. This suit, brought by Dr. Peter M.
Bonutti and by Bonutti Research, Inc., seeks a 50 percent share of the $12.9
million damages judgment GSI obtained in its suit against Origin and seeks
rescission of the 1995 agreement by which GSI obtained assignment of certain
Bonutti technology. From this assigned technology, GSI prosecuted patent
applications which became the '153 and other patents, which credit Dr. Bonutti
as sole inventor. This case is in the discovery phase.

    Patent interference or infringement proceedings involve complex legal and
factual issues and are highly uncertain, and there can be no assurance that any
conclusion reached by GSI regarding patent interference or infringement will be
consistent with the resolution of such issue by a court. In the event the
Company's products are found to infringe patents held by competitors, there can
be no assurance that GSI will be able to modify successfully its products to
avoid infringement, or that any modified products will be commercially
successful. Failure in such event to either develop a commercially successful
alternative or obtain a license to such patent on commercially reasonable terms
would have a material adverse effect on GSI's business, financial condition and
results of operations. As discussed above, GSI is defending itself, and may in
the future have to defend itself, in court against allegations of infringement
of third-party patents. Patent litigation is expensive, requires extensive
management time, and could subject GSI to significant liabilities, require
disputed rights to be licensed from third parties or require GSI to cease
selling its products.

                                       69
<PAGE>
    While GSI believes it will be successful in these proceedings, there can be
no assurance of such success. Failure of GSI to prevail in such proceedings
would have a material adverse effect on GSI's business, financial condition and
results of operations.

    The validity and breadth of claims in medical technology patents involve
complex legal and factual questions and, therefore, may be highly uncertain. No
assurance can be given that any patents based on pending patent applications or
any future patent applications will be issued, that the scope of any patent
protection will exclude competitors or provide competitive advantages to GSI,
that any of GSI's patents or patents to which it has licensed rights will be
held valid under current challenges or if subsequently challenged or that
persons or entities in addition to Origin will not claim rights in or ownership
of the patents and other proprietary rights held or licensed by GSI or that
GSI's existing patents will cover GSI's future products. Furthermore, there can
be no assurance that others have not developed or will not develop similar
products, duplicate any of GSI's products or design around any patents issued to
or licensed by GSI or that may be issued in the future to GSI. Since patent
applications in the United States are maintained in secrecy until patents issue,
GSI also cannot be certain that others did not first file applications for
inventions covered by GSI's pending patent applications, nor can GSI be certain
that it will not infringe any patents that may issue to others on such
applications.

    The patent laws of European and certain other foreign countries generally do
not allow for the issuance of patents for methods of surgery on the human body.
Accordingly, the ability of GSI to gain patent protection for its methods of
tissue dissection will be significantly limited. As a result, there can be no
assurance that GSI will be able to develop a patent portfolio in Europe or that
the scope of any patent protection will provide competitive advantages to GSI.

    ROYALTY PAYMENT OBLIGATIONS.  GSI has acquired rights to patents from third
parties, including rights that apply to GSI's current surgical balloon
dissectors. GSI has historically paid and is obligated to pay in the future to
such third parties royalties equal to between one and four percent of sales of
such products, which payments are expected to exceed minimum royalty payments
due under agreements with such parties. The payment of such royalty amounts will
have an adverse impact on GSI's gross profit and other results of operations.
There can be no assurance that GSI will be able to continue to satisfy such
royalty payment obligations in the future, and a failure to do so could have a
material adverse effect on GSI's business, financial condition and results of
operations.

    COMPETITION; UNCERTAINTY OF TECHNOLOGICAL CHANGE.  Competition in the market
for medical devices and tissue dissection products is intense and is expected to
increase. GSI competes primarily with other producers of MIS tissue dissection
products. Origin, which was a subsidiary of Guidant Corporation and has recently
been purchased by Tyco, was previously, and will continue through November 15,
1999 (pending the outcome of current litigation), to be GSI's primary direct
competition in the field of balloon dissection products. Other companies
currently compete against GSI in the development, production and marketing of
MIS tissue dissection instruments and technology, such as blunt dissectors,
insufflation dissection and aqua irrigation with blunt dissection. To the extent
that surgeons elect to use open surgical procedures rather than MIS, GSI also
competes with producers of tissue dissection products used in open surgical
procedures, such as blunt dissectors or graspers. A number of companies
currently compete against GSI in the development, production and marketing of
tissue dissection products and technology for open surgical procedures. In
addition, GSI competes indirectly with producers of therapeutic drugs, when such
drugs are used as an alternative to surgery. Many of GSI's competitors and
potential competitors have substantially greater name recognition and capital
resources than GSI and also have greater resources and expertise in the areas of
research and development, the obtaining of regulatory approvals, and in
manufacturing and marketing.

    GSI believes that the primary competitive factors in the market for tissue
dissection products include safety, efficacy, ease of use, quality, reliability
and cost effectiveness. In addition, the length of

                                       70
<PAGE>
time required for products to be developed and to receive regulatory approval is
an important competitive factor. GSI believes that it competes favorably with
respect to these factors, although there can be no assurance that it will
continue to do so.

    The market for tissue dissection products is characterized by rapid
technical innovation. Product development involves a high degree of risk, and
there can be no assurance that GSI's competitors and potential competitors will
not succeed in developing and marketing technologies and products that are more
effective than those developed and marketed by GSI or that would render GSI's
technology and products obsolete or noncompetitive. The medical applications for
which GSI's MIS tissue dissection products are used can also be addressed by
other medical devices in either MIS or open surgical procedures, many of which
are widely accepted in the medical community. There can be no assurance that a
procedure using MIS balloon dissection technology will be able to replace such
established products and procedures. Additionally, new surgical products or
procedures could be developed that replace or reduce the importance of current
procedures that use GSI's products.

    UNCERTAIN AVAILABILITY OF THIRD-PARTY REIMBURSEMENT.  GSI's success will
depend upon the ability of surgeons to obtain satisfactory reimbursement from
healthcare payors for GSI's products. In the United States, hospitals,
physicians and other healthcare providers that purchase medical devices
generally rely on third-party payors, such as private health insurance plans, to
reimburse all or part of the costs associated with the treatment of patients.
Reimbursement in the United States for GSI's balloon dissection products is
currently available from most third-party payors, including most major private
health care insurance plans and Medicaid, under existing surgical procedure
codes. GSI does not expect that third-party reimbursement in the United States
will be available for use of some of its other products unless and until
clearance or approval is received from the federal Food and Drug Administration.
However, given the efforts to control and decrease health care costs in recent
years, there can be no assurance that any reimbursement will be sufficient to
permit GSI to increase revenues or achieve or maintain profitability. The
unavailability of third-party or other adequate reimbursement in the United
States could have a material adverse effect on GSI's business, financial
condition and results of operations.

    Reimbursement systems in international markets vary significantly by
country, and by region within some countries, and reimbursement approvals must
be obtained on a country-by-country basis. Many international markets have
government-managed health care systems that govern reimbursement for new devices
and procedures. In most markets, there are private insurance systems as well as
government-managed systems. Large-scale market acceptance of GSI's surgical
balloon dissectors and other products will depend on the availability and level
of reimbursement in international markets targeted by GSI. Failure to obtain
such approvals for reimbursement in international markets could have a material
adverse effect on GSI's business, financial condition and results of operations.

    Regardless of the type of reimbursement system, GSI believes that surgeon
advocacy of its products will be required to obtain reimbursement. There can be
no assurance that surgeons will support and advocate reimbursement for use of
GSI's systems for all applications intended by GSI. Failure by surgeons,
hospitals and other users of GSI's products to obtain sufficient reimbursement
from health care payors or adverse changes in government and private third-party
payors' policies toward reimbursement for procedures employing GSI's products
could have a material adverse effect on GSI's business, financial condition and
results of operations.

    GOVERNMENT REGULATION.  GSI's products are subject to extensive and rigorous
regulation by the FDA and, to varying degrees, by state and foreign regulatory
agencies. Under the federal Food, Drug, and Cosmetic Act, the FDA regulates the
clinical testing, manufacture, labeling, packaging, marketing, distribution and
record keeping for medical devices, in order to ensure that medical devices
distributed in the United States are safe and effective for their intended use.
Prior to commercialization, a medical device generally must receive FDA and
foreign regulatory clearance or approval, which can be an

                                       71
<PAGE>
expensive, lengthy and uncertain process. GSI is also subject to routine
inspection by the FDA and state agencies, such as the California Department of
Health Services ("CDHS"), for compliance with Good Manufacturing Practice
requirements, Medical Device Reporting requirements and other applicable
regulations. Noncompliance with applicable requirements can result in warning
letters, import detentions, fines, civil penalties, injunctions, suspensions or
losses of regulatory approvals, recall or seizure of products, operating
restrictions, refusal of the government to approve product export applications
or allow GSI to enter into supply contracts, and criminal prosecution. Delays in
receipt of, or failure to obtain, regulatory clearances and approvals, if
obtained, or any failure to comply with regulatory requirements could have a
material adverse effect on GSI's business, financial condition and results of
operations.

    Labeling and promotional activities are subject to scrutiny by the FDA and,
in certain circumstances, by the Federal Trade Commission. Current FDA
enforcement policy prohibits the marketing of approved medical devices for
unapproved uses. The SPACEMAKER-Registered Trademark- I platform,
SPACEMAKER-Registered Trademark- II platform, SPACEMAKER-Registered Trademark-
Plastics platform and SPACEMAKER-Registered Trademark-
SAPHtrak-Registered Trademark- platform each have received 510(k) clearance for
use during general, endoscopic, laparoscopic and plastic and reconstructive
surgery (including aesthetic), and certain vascular surgery (including saphenous
vein procedures) when tissue dissection is required. Additionally, GSI has
received clearance to market these products for thoracoscopic procedures
involving exposure and dissection of structures external to the parietal pleura
and procedures in the extraperitoneal space. GSI has also received clearance to
market combined tissue dissection/expansion products. GSI has promoted these
products for surgical applications (E.G., hernia repair, SEPS, breast
augmentation and reconstruction, treatment of SUI and saphenous vein
harvesting), and may in the future promote these products for the dissection
required for additional selected applications (E.G., tissue dissection/expansion
and a variety of procedures which require exposure to the anterior spine or for
long-bone plating). For any medical device cleared through the 510(k) process,
modifications or enhancements that could significantly affect the safety or
effectiveness of the device or that constitute a major change to the intended
use of the device will require a new 510(k) submission. GSI has made
modifications to its products which GSI believes do not affect the safety or
effectiveness of the device or constitute a major change to the intended use and
therefore do not require the submission of new 510(k) notices. There can be no
assurance, however, that the FDA will agree with any of GSI's determinations not
to submit a new 510(k) notice for any of these changes or will not require GSI
to submit a new 510(k) notice for any of the changes made to the product. If
such additional 510(k) clearances are required, there can be no assurance that
GSI will obtain them on a timely basis, if at all, and delays in receipt of or
failure to receive such approvals could have a material adverse effect on GSI's
business, financial condition and results of operations. If the FDA requires GSI
to submit a new 510(k) notice for any product modification, GSI may be
prohibited from marketing the modified product until the 510(k) notice is
cleared by the FDA.

    Sales of medical devices outside of the United States are subject to foreign
regulatory requirements that vary widely from country to country. GSI currently
relies on its international distributors for the receipt of premarket approvals
and compliance with clinical trial requirements in those countries that require
them, and it expects to continue to rely on distributors in those countries
where GSI continues to use distributors. In the event that GSI's international
distributors fail to obtain or maintain premarket approvals or compliance in
foreign countries where such approvals or compliance are required, GSI may be
required to cause the applicable distributor to file revised governmental
notifications, cease commercial sales of its products in the applicable
countries or otherwise act so as to stop any ongoing noncompliance in such
countries. Any enforcement action by regulatory authorities with respect to past
or any future regulatory noncompliance could have a material adverse effect on
GSI's business, financial condition and results of operations.

                                       72

    LIMITED MANUFACTURING EXPERIENCE.  GSI has only limited experience in
manufacturing its products in commercial quantities. Manufacturers often
encounter difficulties in scaling up production of new products, including
problems involving production yields, quality control and assurance, component
supply and shortages of qualified personnel. Difficulties experienced by GSI in
manufacturing scale-up and manufacturing difficulties could have a material
adverse effect on its business, financial condition and results of operations.
There can be no assurance that GSI will be successful in scaling up or that it
will not experience manufacturing difficulties or product recalls in the future.

    DEPENDENCE ON SINGLE SOURCE SUPPLIERS; LACK OF CONTRACTUAL
ARRANGEMENTS.  GSI currently relies upon single source suppliers for several
components of its balloon dissection products, and in most cases there are no
formal contracts with such suppliers. There can be no assurance that the
component materials obtained from single source suppliers will continue to be
available in adequate quantities or, if required, that GSI will be able to
locate alternative sources of such component materials on a timely basis to
market its products, if at all. In addition, there can be no assurance that the
single source suppliers will meet GSI's future requirements for timely delivery
of products of sufficient quality and quantity. The failure to obtain sufficient
quantities and qualities of such component materials, or the loss of any of
GSI's single source suppliers, could cause a delay in GSI's ability to fulfill
orders while it attempts to identify and certify a replacement supplier and
could have a material adverse effect on GSI's business, financial condition and
results of operations.

    PRODUCT LIABILITY RISK AND PRODUCT RECALL; LIMITED INSURANCE
COVERAGE.  GSI's business exposes it to potential product liability risks or
product recalls that are inherent in the design, development, manufacture and
marketing of medical devices, in the event the use of GSI's products cause or
are alleged to have caused adverse effects on a patient or such products are
believed to be defective. GSI's products are designed to be used in certain
procedures where there is a high risk of serious injury or death. Such risks
will exist even with respect to those products that have received, or may in the
future receive, regulatory clearance for commercial sale. As a result, there can
be no assurance that GSI's product liability insurance is adequate or that such
insurance coverage will continue to be available on commercially reasonable
terms or at all. Particularly given the lack of data regarding the long-term
results of the use of balloon dissection products, there can be no assurance GSI
will avoid significant product liability claims. Consequently, a product
liability claim or other claim with respect to uninsured or underinsured
liabilities could have a material adverse effect on GSI's business, financial
condition and results of operations.

    DEPENDENCE ON MANAGEMENT AND OTHER KEY PERSONNEL.  GSI is dependent upon a
limited number of key management and technical personnel. The loss of the
services of one or more of such key employees could have a material adverse
effect on GSI's business, financial condition, and results of operations. In
addition, GSI's success will be dependent upon its ability to attract and retain
additional highly qualified sales, management, manufacturing and research and
development personnel. GSI faces intense competition in its recruiting
activities and there can be no assurance that GSI will be able to attract and/or
retain qualified personnel.

    POTENTIAL VOLATILITY OF STOCK PRICE.  The market prices of GSI common stock
and the stock of many other publicly held medical device companies have in the
past been, and can in the future be expected to be, especially volatile.
Announcements regarding competitive developments, product sales, clinical
marketing trial results, release of reports by securities analysts, developments
or disputes concerning patents or proprietary rights, regulatory developments,
changes in regulatory or medical reimbursement policies, economic and other
external factors, as well as period-to-period fluctuations in GSI's financial
results, may have a significant impact on the market price of the common stock.
In addition, the securities markets have from time to time experienced
significant price and volume fluctuations that are unrelated to the operating
performance of particular companies.

    YEAR 2000 COMPLIANCE.  The Year 2000 ("Y2K") issue arises from computer
programs using two digits rather than four to define the applicable year. Such
software may recognize a date using "00" as the year 1900 rather than the year
2000. This could result in system failures or miscalculations leading to
disruptions or delays in GSI's activities and operations. If GSI, its key
customers or suppliers fail to make necessary modifications to their information
technology or non-information technology systems on a timely basis, the Y2K
issue could have a material adverse effect on GSI's operations. However, the
impact cannot be quantified at this time.

    In January 1998 GSI began to evaluate and assess its information technology
and non-information technology systems for compliance with the Y2K issue. GSI
intends to fix or replace noncompliant software and systems by November 30,
1999, but there can be no assurance that such fixes or replacements will occur
by such date. GSI is currently conducting testing and remediation activities on
its systems, and intends to survey major customers and suppliers to assess their
systems' compliance as well as their systems' compatibility with GSI's existing
or projected compliant systems. There can be no assurance that there will not be
an adverse material effect on GSI's business, financial condition or results of
operations if GSI or its suppliers or customers do not convert or replace their
systems in a timely manner to comply with the Y2K issue. See "Management's
Discussion and Analysis of Financial Condition and Results of
Operations--Management Information Systems".

                      COMPARISON OF RIGHTS OF SHAREHOLDERS
                        OF GSI AND SHAREHOLDERS OF TYCO

    GSI is a California corporation, and the rights of GSI's shareholders are
governed by GSI's Amended and Restated Articles of Incorporation and Bylaws and
by California law. Upon the consummation of the merger, shareholders of GSI will
become shareholders of Tyco and their rights will be governed by Tyco's
Memorandum of Association and Bye-laws and by Bermuda law.

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

    Copies of Tyco's Memorandum of Association and Bye-laws and GSI's Amended
and Restated Articles of Incorporation and Bylaws have been filed with the SEC
and will be sent to holders of GSI common stock upon request. See "Where You Can
Find More Information" on page   .

  potential change in control of GSI a potentially

To the Board of Directors and Shareholders of
General Surgical Innovations, Inc.:

    In our opinion, the accompanying balance sheets and the related statements
of operations and comprehensive loss, of shareholders' equity and of cash flows
present fairly, in all material respects, the financial position of General
Surgical Innovations, Inc. at June 30, 1999 and 1998, and the results of its
operations and its cash flows for each of the three years in the period ended
June 30, 1999, in conformity with generally accepted accounting principles.
These financial statements are the responsibility of the Company's management;
our responsibility is to express an opinion on these financial statements based
on our audits. We conducted our audits of these statements in accordance with
generally accepted auditing standards which require that we plan and perform the
audit to obtain reasonable assurance about whether the financial statements are
free of material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the financial statements,
assessing the accounting principles used and significant estimates made by
management, and evaluating the overall financial statement presentation. We
believe that our audits provide a reasonable basis for the opinion expressed
above.

                         NOTES TO FINANCIAL STATEMENTS

1. FORMATION AND BUSINESS OF GSI:

    General Surgical Innovations, Inc. ("GSI") was incorporated on April 13,
1992, to engage in the development, manufacturing and marketing of medical
device surgical balloon dissectors which create new working spaces between
natural tissue planes in the human body. GSI sells products in the United
States, Europe, Australia and South America, through its direct sales force and
key distributors. While GSI has developed or is developing surgical balloon
dissectors for stress urinary incontinence, vascular and plastic surgery, sales
of products for hernia repair are expected to provide a majority of GSI's
revenues at least through fiscal 2000.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

    USE OF ESTIMATES:

    The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements, and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.

    CASH AND CASH EQUIVALENTS:

    GSI considers investments with an original maturity of 90 days or less as of
the date of purchase to be cash equivalents.

    AVAILABLE-FOR SALE SECURITIES:

    GSI has classified its investments as "available-for-sale." Such investments
are recorded at fair value, and unrealized holding gains and losses are recorded
net of related taxes as a separate component of shareholders' equity. Interest
income is recorded using an effective interest rate, with associated premium or
discount amortized to "investment income." Realized gains and losses on sales of
all such securities are reported in earnings and computed using the specific
identification cost method. All investments with maturity dates greater than 365
days are classified as non-current.

    INVENTORIES:

    Inventories are stated at the lower of cost or market. Cost is based on
actual costs computed on a first-in, first-out basis.

    PROPERTY AND EQUIPMENT:

    Property and equipment are stated at cost, net of accumulated depreciation
and amortization. Furniture, fixtures, equipment and tooling are depreciated on
a straight-line basis over their estimated useful lives of three to five years.
Leasehold improvements are amortized over the lesser of their estimated useful
lives or the term of the lease.

    INTANGIBLE ASSETS:

    Intangible assets include patents which are being amortized on a
straight-line basis over five years. GSI periodically assesses the
recoverability of intangible assets by determining whether amortization of the
asset balance over the remaining life can be recovered through undiscounted
future operating cash

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES: (CONTINUED)
flows of the acquired operation. The amount of impairment, if any, is measured
based on projected discounted future operating cash flows and is recognized as a
write down of the asset to net realizable value.

    EMPLOYEE STOCK PLANS:

    GSI accounts for its stock option plans and its employee stock purchase plan
in accordance with the provisions of the Accounting Principles Board's Opinion
No. 25 ("APB 25"), "Accounting for Stock Issued to Employees." In 1995, the
Financial Accounting Standards Board issued Statement of Financial Accounting
Standards No. 123 ("SFAS 123"), "Accounting for Stock-Based Compensation." SFAS
123 establishes a fair value based method of accounting for stock-based plans
and is effective for fiscal years beginning after December 15, 1995. GSI is
continuing to account for its employee stock plans in accordance with the
provisions of APB 25, and has provided pro forma disclosure in Note 6 as if the
measurement provisions of SFAS 123 had been adopted.

    REVENUE RECOGNITION:

    GSI recognizes revenue from product sales upon shipment of product and when
title passes to its customer. Allowances are provided for estimated returns.
Revenue from guaranteed payments is recognized in the period received according
to the terms and conditions of a distributor agreement.

    RESEARCH AND DEVELOPMENT:

    Research and development expenses are charged to operations as incurred.

    BUSINESS RISKS AND CREDIT CONCENTRATION:

    A substantial portion of GSI's sales have been derived from sales of its
surgical balloon dissectors for hernia repair procedures. Failure of GSI to
successfully develop and commercialize surgical balloon dissector products for
applications other than hernia repair could have a material adverse effect on
GSI's business, financial condition and results of operations.

    In March 1994, GSI entered into a distribution agreement with United States
Surgical Corporation ("USSC") providing USSC with limited exclusive rights to
distribute GSI's surgical balloon dissectors in the hernia repair market in both
the United States and certain other countries. In fiscal 1997 and 1996, sales to
USSC, which include sales to Autosuture, Inc., a subsidiary of USSC, represented
approximately 27 percent and 92 percent, respectively, of GSI's sales. In
November 1996, GSI terminated its distribution agreement with USSC; there were
no sales to USSC in fiscal 1998. In September 1998, GSI signed two
non-exclusive, three-year agreements with USSC. Under the terms of the first
agreement, USSC has obtained non-exclusive rights to market and distribute GSI's
SPACEMAKER(R) surgical balloon dissectors worldwide for use in hernia repair and
stress urinary incontinence ("SUI") procedures. Under the terms of the second
agreement, GSI has non-exclusive rights to market and distribute several
products, including USSC's 5 mm mesh fixation device, the ProTack(TM), which is
offered with GSI's balloon dissectors in the SPACEMAKER(R)Total Solution(TM)
hernia repair kit. Sales to USSC in fiscal 1999 represented approximately three
percent of GSI's total sales.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES: (CONTINUED)
    In December 1996, GSI entered into a five year OEM supply agreement (the
"EES Agreement") with Ethicon Endo-Surgery ("EES"), pursuant to which GSI
granted EES exclusive worldwide sales and marketing rights to sell the
SPACEMAKER(R) surgical balloon dissectors in the laparoscopic hernia repair and
stress urinary incontinence ("SUI") markets. EES made guaranteed payments
pursuant to the EES Agreement of $4.9 million in fiscal year 1997, and
additional payments in lieu of product purchases pursuant to a mutual agreement
in the amount of $1.6 million in fiscal year 1998. In February 1998, GSI and EES
replaced the exclusive EES Agreement with a non-exclusive distribution agreement
for the laparoscopic hernia repair and SUI markets. In fiscal year 1999, EES
made no guaranteed payments or payments in lieu of product purchases. Sales and
guaranteed payments from EES represented approximately 21 percent, 74 percent
and 65 percent of GSI's 1999, 1998 and 1997 revenues, respectively.

    In May 1999, GSI signed a distribution agreement with Dexterity Surgical,
Inc. ("Dexterity"). The terms of the agreement gave Dexterity rights to market
and distribute GSI's SPACEMAKER(R) balloon dissector products for hernia repair
and laparoscopic bladder neck suspension repair procedures in all or parts of 28
states. In fiscal year 1999, sales to Dexterity represented approximately 23
percent of total company sales.

    GSI maintains its cash balances in demand accounts primarily with one
financial institution. For its accounts receivable, management of GSI performs
ongoing credit evaluations of its customers and maintains allowances for
doubtful accounts. Historically GSI has not experienced significant losses
related to individual customers or groups of customers in any particular
geographic area. At June 30, 1998 and 1997, one distributor accounted for
approximately 46 percent and 93 percent, respectively, of accounts receivable.
At June 30, 1999, another distributor accounted for approximately 46 percent of
accounts receivable.

    FAIR VALUE OF FINANCIAL INSTRUMENTS:

    Carrying amounts of GSI's financial instruments including cash and cash
equivalents, accounts receivable and accounts payable approximate fair values
due to their short maturities. Based on the borrowing rates currently available
to GSI for loans with similar terms, the carrying values of the equipment loan
and line of credit approximate fair values. Estimated fair values for
available-for-sale securities, which are separately disclosed elsewhere, are
based on quoted market prices for the same or similar instruments.

    INCOME TAXES:

    GSI accounts for income taxes under the liability method. Under the
liability method, deferred tax assets and liabilities are determined based on
differences between financial reporting and tax bases of assets and liabilities
and are measured using the enacted tax rates and laws that will be in effect
when the differences are expected to reverse. GSI is required to adjust deferred
tax liabilities in the period when tax rates or the provisions of the income tax
laws change. Valuation allowances are established when necessary to reduce
deferred tax assets to the amounts expected to be realized.

    COMPREHENSIVE INCOME:

    GSI has adopted the provisions of Statement of Financial Accounting
Standards No. 130 ("SFAS 130"), "Comprehensive Income." SFAS 130 establishes
standards for reporting and display of

                                      F-9

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES: (CONTINUED)
comprehensive income and its components for general-purpose financial
statements. Comprehensive income is defined as net income plus all revenues,
expenses, gains and losses from non-owner sources that are excluded from net
income in accordance with generally accepted accounting principles.

    COMPUTATION OF NET LOSS PER COMMON SHARE AND PER COMMON SHARE-ASSUMING
     DILUTION:

    Net loss per common share and per common share-assuming dilution are
computed using the weighted average number of shares of common stock
outstanding. Common equivalent shares from stock options are excluded from the
computation of net loss per common share-assuming dilution as their effect is
antidilutive.

    Stock options to purchase 2,245,655, 1,816,906 and 1,363,447 shares of
common stock at prices ranging from $0.09 to $9.75 per share were outstanding at
June 30, 1999, 1998 and 1997, respectively, but were not included in the
computation of net loss per common share-assuming dilution because they were
antidilutive. The aforementioned stock options could potentially dilute earnings
per share in the future.

    RECENT PRONOUNCEMENTS:

    In June 1998, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 133 ("SFAS 133"), "Accounting for Derivative
Instruments and Hedging Activities," which establishes accounting and reporting
standards for derivative instruments and hedging activities. It requires that an
entity recognize all derivatives as either assets or liabilities in the
statement of financial position and measure those instruments at fair value. To
date, GSI has not engaged in derivative and hedging activities. SFAS 133 will be
effective for fiscal years beginning after June 15, 2000.

4. BANK BORROWINGS:

    On March 25, 1996, GSI entered into a loan agreement with a financial
institution which provides for an equipment loan of $700,000 with interest at
the bank's prime rate plus 1.25 percent (9.00 percent at June 30, 1999). The
note matures on June 30, 2000. Future minimum payments under the loan are
$82,000 in the fiscal year ending June 30, 2000.

    The bank borrowings are collateralized by substantially all of GSI's assets.
In addition, GSI is required to maintain certain restrictive financial covenants
including minimum tangible net worth and a minimum quick ratio.

5. COMMITMENTS AND CONTINGENCIES:

    Rent expense for the years ended June 30, 1999, 1998 and 1997 was $635,244,
$625,488, and $600,645, respectively.

    CAPITAL LEASE AGREEMENTS:

    The Company has two capital lease agreements for office equipment. Amounts
financed under these leases total approximately $41,000, with associated
accumulated depreciation of $29,000. Future minimum lease payments under these
capital leases are $12,000 in the fiscal year ending June 30, 2000.

    OTHER COMMITMENTS:

    The Company has entered into certain royalty agreements to obtain technology
which provide for royalties ranging from one to four percent of the sales price
for products which utilize this technology. Amounts charged to operations for
the years ended June 30, 1999, 1998 and 1997 were $187,497, $289,255 and
$356,831, respectively.

    Also, in 1994 in conjunction with obtaining technology, GSI entered into a
royalty agreement that provides for royalties of four percent of net sales for
products which utilize this technology through 2001. Minimum royalties under the
agreement are $75,000, $87,500 and $50,000 for the years ending June 30, 2000,
2001 and 2002, respectively.

    CONTINGENCIES:

    In May 1996, Origin Medsystems, Inc. ("Origin") a unit of Guidant
Corporation filed suit against GSI for infringement of U.S. Patent No. 5,520,609
in the United States District Court for the Northern District of California
(C96-20424JW). In April 1998, GSI obtained a summary judgment that the patent in
suit, Moll et al Patent No. 5,520,609, was unenforceable because it had been
obtained by misleading the Patent & Trademark Office, and an award of attorney's
fees of $990,000. The appellate court subsequently vacated this decision
because, in its view, there are factual issues which must be resolved in a trial
on whether Origin misled the PTO. In July 1999, the case was returned to the
district court for further proceedings.

    In June 1996, GSI filed an action against Origin in the U.S. District Court
for the Northern District of California alleging that the use of Origin's
products infringes GSI's U.S. Patent No. 5,514,153 (C96-20447JW). The case was
decided in favor of GSI partly by summary judgment and partly by jury verdict,
both during fiscal 1999. Patent 5,514,153 ("the '153 patent") was found to be
valid, and Origin's infringement was found to be willful. Lost profits of
approximately $12.9 million were awarded to GSI by the jury. Origin is appealing
the infringement and willfulness findings (but not patent validity nor the
amount of infringement damages), and GSI is appealing for enhanced damages,

attorneys' fees and the failure to find infringement of additional claims. The
Company has not recorded a receivable for this gain contingency. Resolution is
expected in calendar year 2000. Following these findings, the Court has entered
an injunction prohibiting sale in the United States of all of Origin's balloon
dissection products, to become fully effective on November 15, 1999, and an
immediate injunction against sales to any new customers.

    In September 1997, GSI filed an action against Origin alleging that the use
of Origin's products infringes GSI's U.S. Patent No. 5,667,520 (C97-20944JW).
Discovery is nearly complete in this case and the complaint has now been amended
to add a claim of infringement of GSI's patent number 5,860,997. This case is
now stayed pending the outcome of appeals in the '153 case.

    GSI is also involved in an interference proceeding in the U.S. Patent Office
against Origin to determine whether certain subject matter was first invented by
GSI and whether the disputed matter is patentable. In November 1998, binding
arbitration determined that GSI was first to invent the disputed subject matter
and therefore is the only party entitled to any patent. Additionally, the Patent
Office Appeals Board found the subject matter to be patentable. This latter
finding is being appealed by Origin to the Court of Appeals for the Federal
Circuit. Resolution is expected in calendar year 2000.

    On April 9, 1999, a suit was filed against GSI in the United States District
Court for the Southern District of Illinois. This suit, brought by Dr. Peter M.
Bonutti and by Bonutti Research, Inc., seeks a 50 percent share of the $12.9
million damages judgment GSI obtained in its suit against Origin and seeks
rescission of the 1995 agreement by which GSI obtained assignment of certain
Bonutti technology. From this assigned technology, GSI prosecuted patent
applications which became the '153 and other patents, which credit Dr. Bonutti
as sole inventor. This case is in the discovery phase.

    While GSI believes it will be successful in these proceedings, there can be
no assurance of such success. Failure of the Company to prevail in such
proceedings would have a material adverse effect on GSI's business, financial
condition and results of operations.

6. SHAREHOLDERS' EQUITY:

    PREFERRED STOCK:

    Under GSI's Articles of Incorporation, GSI's preferred stock is issuable in
series and GSI's Board of Directors is authorized to determine the rights,
preferences and terms of each series.

    During 1996, GSI amended its Articles of Incorporation to authorize
2,000,000 shares of undesignated preferred stock. Preferred stock may be issued
from time to time in one or more series. As of June 30, 1999, the Company had no
shares issued and outstanding.

    COMMON STOCK:

    The Company has issued through June 30, 1999, shares of its common stock to
the founders and key employees of GSI under stock purchase agreements. Certain
stock purchase agreements (the "Agreements") contain provisions for the
repurchase of common stock by GSI in the event of termination of employment
during the vesting period following the date of employment. Generally, 25
percent of the shares of common stock purchased under the Agreements are
released from GSI's repurchase option at the end of twelve months from a
participant's hiring date with the remaining shares being released from
repurchase ratably over the next 36 months. At June 30, 1999, 14,897 shares are
subject to repurchase under the Agreements. Each share of common stock has the
right to one vote. The holders of common stock are also entitled to receive
dividends whenever funds are legally available and when declared by the Board of
Directors, subject to the prior rights of holders of any class of outstanding
stock having priority rights as to dividends.

    STOCK OPTION PLANS:

    1992 STOCK OPTION PLAN

    GSI has an Incentive Stock Option Plan (the "Plan") under which 1,715,895
shares of common stock were originally reserved for issuance. An additional
500,000 and 400,000 shares were reserved in November 1997 and November 1996,
respectively, bringing the aggregate number of shares of common stock reserved
for issuance to 2,615,895 as of June 30, 1998. In November 1998, the Plan was
amended to: (i) increase the number of shares of common stock reserved for
issuance thereunder on the date of each annual meeting of the shareholders
during the period beginning on and including November 19, 1998 and ending
September 14, 2002 (the date the 1992 Plan terminates) by an amount equal to the
lesser of (x) four percent (four percent) of the total number of shares of GSI's
common stock issued and outstanding as of the last business day immediately
preceding the date of such annual meeting, or (y) 600,000 shares, and (ii)
increase the total maximum number of shares subject to options that may be
issued to any one employee during a fiscal year to 1,000,000 (effective as of
July 1, 1998). The maximum aggregate number of shares of common stock that may
be issued under the 1992 Plan is 5,015,895. At this time, an additional 438,773
shares were reserved, bringing the aggregate number of shares of common stock
reserved for issuance to 3,054,668 as of June 30, 1999.

    Under the Plan, incentive options may be granted at prices not lower than
fair market value at the date of grant or 110 percent of the fair market value
if the optionee, immediately prior to the grant, owns stock representing 10
percent or more of the voting power or value of all securities. Nonstatutory
options may be granted at prices not lower than 85 percent of fair market value
at the date of grant as determined by the Board of Directors. Options granted
under the Plan are exercisable and vest at such times and under such conditions
as determined by the Board. The options generally expire from five years to ten
years from date of grant.

    1995 DIRECTORS' STOCK OPTION PLAN

    In November 1995, GSI adopted the Directors' Stock Option Plan ("the
Directors' Plan"), under which 164,726 shares of common stock have been reserved
for issuance. The Directors' Plan provides for the grant of nonstatutory stock
options to non-employee directors of GSI. The Directors' Plan provides an
initial option to purchase 27,454 shares of common stock, which vests annually
over four years, and beginning with the 1997 annual meeting, provides an
additional annual option to purchase 6,864 shares of common stock.

    The exercise price of all stock options granted under the Directors' Plan
shall be equal to the fair market value of GSI's common stock on the date of
grant of the option. Options granted under the Directors' Plan have a term of
ten years.

    An additional 25,000 shares have been granted outside of the above stock
options plans.

    At June 30, 1998 and 1997, options to purchase 679,327 and 434,609 shares
were exercisable at a weighted average exercise price of $2.49 and $1.60 per
share, respectively.

    Compensation of approximately $600,000 has been attributed to stock options
granted after May 1995 and prior to the sale of GSI's common stock in an initial
public offering. The deferred compensation is being recognized as a charge to
income over the period for which the related stock options become exercisable,
which is generally four years. Amortization of the deferred compensation was
approximately $137,000, $138,000 and $199,000 during the years ended June 30,
1999, 1998 and 1997, respectively.

6. SHAREHOLDERS' EQUITY: (CONTINUED)
    On August 5, 1997, GSI repriced 357,034 options, ranging in price from $5.63
to $22.25 per share, to the fair market value on that date of $4.38 per share.

    GSI implemented a stock option exchange program effective October 6, 1998,
pursuant to which all holders of options issued under the 1992 Plan may
surrender for cancellation all options granted after May 10, 1996 (the date of
GSI's initial public offering) with a price above $1.5601, the fair market value
on the effective date. GSI cancelled 1,127,876 options, ranging in price from
$2.00 to $9.75, and reissued the same number of new options for an exercise
price of $1.5601. The new options were subject to a nine month restriction on
exercise (until July 6, 1999), subject to certain exceptions. All executive
officers of GSI were eligible to participate in the option exchange program.

    PRO FORMA INFORMATION:

    Had compensation costs for options awarded in fiscal 1999, 1998 and 1997
been determined based on the fair value at the grant date consistent with the
provisions of SFAS 123, GSI's net loss and net loss per share would have
resulted in the pro forma amounts indicated in the following (IN THOUSANDS,

    EMPLOYEE STOCK PURCHASE PLAN:

    In March 1996, the Board of Directors adopted the 1996 Employee Stock
Purchase Plan (the "ESPP") and reserved 274,543 shares of common stock for
issuance. The purpose of the ESPP is to provide eligible employees of GSI with a
means of acquiring common stock of GSI through payroll deductions. The purchase
price of such stock under the ESPP cannot be less than 85 percent of the

lower of the fair market value on the specified purchase date or at the
beginning of the offering period. At June 30, 1999, 69,670 shares had been
issued under the ESPP.

    COMMON STOCK PURCHASE RIGHTS:

    In May 1997, GSI distributed a dividend to shareholders comprised of a right
to purchase one share of common stock (a "Right") for each outstanding share of
common stock of GSI they hold. These Rights do not become exercisable or
transferable apart from the common stock until the Distribution Date which is
the tenth day after a person or group either (a) acquires beneficial ownership
of 15 percent or more of GSI's common stock or (b) announces a tender or
exchange offer, the consummation of which would result in ownership by a person
or group of 15 percent or more of GSI's common stock. After the Distribution
Date, each Right will entitle the holder to purchase from GSI one share of
common stock at a price of $35 per share.

    If GSI is acquired in a merger or other business combination transaction, or
if 50 percent or more of its assets or earnings power is sold, each Right will
entitle the holder to purchase at the exercise price that number of shares of
the acquiring company having a then current market value of two times the
exercise price of the Right. In the event that GSI is the surviving corporation
in a merger and GSI's common stock remains outstanding, or in the event that an
acquiring party engages in certain self-dealing transactions, each Right not
owned by the acquiring party will entitle the holder to purchase at the exercise
price that number of shares of GSI's common stock having a then current market
value of two times the exercise price of the Right.

    The Rights are redeemable at GSI's option for $.01 per Right prior to
becoming exercisable, may be amended at GSI's option on or prior to the
Distribution Date and expire on May 8, 2007.

7. EMPLOYEE BENEFIT PLAN:

    GSI has a qualified 401(k) plan available to substantially all employees
over the age of 21. Participants may contribute up to 20 percent of their annual
compensation to the plan, limited to a maximum amount set by the Internal
Revenue Service. GSI may make contributions to the 401(k) plan at the discretion
of the Board of Directors. No Company contributions have been made to the plan
since inception.

8. INCOME TAXES:

    At June 30, 1999, GSI had federal and state net operating loss carryforwards
of $37.3 million and $11.5 million, respectively, which expire in the years 1999
- -2019.

    As a result of a change in ownership, as defined, federal and state net
operating loss carryforwards are subject to an annual limitation of $400,000.

    In accordance with generally accepted accounting principles, a valuation
allowance must be established for a deferred tax asset if it is more likely than
not that a tax benefit will not be realized from the asset in the future. GSI
has established a valuation allowance to the extent of its deferred tax assets
since it is more likely than not that a benefit will not be realized in the
future due to GSI's recurring operating losses.

    GSI's effective tax rate differs from the statutory federal income tax rate
as shown in the following schedule:

9. RELATED PARTY TRANSACTIONS:

    GSI entered into certain product development arrangements and royalty
agreements with a sole proprietorship which is owned by a director of GSI. Under

                              W I T N E S S E T H:

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

    WHEREAS, in furtherance of such combination, the Boards of Directors of
Parent, Merger Sub and the Company have each approved the merger (the "MERGER")
of Merger Sub with and into the Company in accordance with the applicable
provisions of the California General Corporation Law (the "CGCL"), and upon the
terms and subject to the conditions set forth herein;

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

    WHEREAS, pursuant to the Merger, each outstanding share (together with the
common stock purchase right associated therewith, a "SHARE") of the Company's
common stock, par value $0.001 per share (the "COMPANY COMMON STOCK"), shall be
converted into the right to receive the Merger Consideration (as defined in
Section 1.07(b)), upon the terms and subject to the conditions set forth herein;

    WHEREAS, concurrently with the execution and delivery of this Agreement, and
as a condition to the Company's willingness to enter into this Agreement,
Guarantor has agreed fully and unconditionally to guarantee the representations,
warranties, covenants, agreements and other obligations of Parent and Merger Sub
in this Agreement (the "GUARANTEE"); and

    WHEREAS, as a condition and inducement to Parent entering into this
Agreement and incurring the obligations set forth herein, concurrently with the
execution and delivery of this Agreement, Parent is entering into a Voting
Agreement with each of certain shareholders of the Company (each, a "SELLING
SHAREHOLDER"), in the form of EXHIBIT A hereto (the "VOTING AGREEMENT") pursuant
to which, among other things, such Selling Shareholder has agreed to vote the
shares of Company Common Stock owned by such Selling Shareholder in favor of
this Agreement and the Merger provided for herein;

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

                                   ARTICLE I

with and into the Company, the separate corporate existence of Merger Sub shall
cease, and the Company shall continue as the surviving corporation (hereinafter
sometimes referred to as the "SURVIVING CORPORATION").

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

hold office until the next annual meeting. Each director, including a director
elected to fill a vacancy, shall hold office until the expiration of the term
for which such director was elected and until a successor has been elected and
qualified."

    SECTION 1.05.  DIRECTORS AND OFFICERS.  The directors of Merger Sub
immediately prior to the Effective Time shall be the initial directors of the
Surviving Corporation, each to hold office in accordance with the Articles of
Incorporation and By-laws of the Surviving Corporation, and the officers of the
Company immediately prior to the Effective Time shall be the initial officers of
the Surviving Corporation, in each case until their respective successors are
duly elected or appointed and qualified.

    SECTION 1.06.  EFFECT ON SECURITIES, ETC.  At the Effective Time, by virtue
of the Merger and without any action on the part of Parent, Merger Sub, the
Company or the holders of any securities of the Company:

    (a)  CONVERSION OF SECURITIES.  Each Share issued and outstanding
immediately prior to the Effective Time (excluding any Shares to be canceled
pursuant to Section 1.06(b) and any Dissenting Shares) shall be converted,
subject to Sections 1.06(e), 1.06(f) and 7.01(j), into the right to receive from
Parent a fraction of a validly issued, fully paid and nonassessable common
share, par value $0.20 per share, of Guarantor (a "GUARANTOR COMMON SHARE") such
fraction to be in the ratio (the "EXCHANGE RATIO") of $7.50 divided by the
Average Share Price.

    "AVERAGE SHARE PRICE" means the average of the Daily Per Share Prices (as
hereinafter defined) for the five consecutive trading days ending on the fourth
trading day prior to date of the Company Shareholders Meeting (as defined in
Section 2.13). The "DAILY PER SHARE PRICE" for any trading day means the
volume-weighted average of the per share selling prices on the New York Stock
Exchange, Inc. (the "NYSE") of Guarantor Common Shares (as reported in the NYSE
Composite Transaction Tape) for that day.

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

    (c)  STOCK OPTIONS.  At the Effective Time, by virtue of the Merger and
without any further action on the part of the holders thereof, each outstanding
option to purchase shares of Company Common Stock (collectively, the "COMPANY
STOCK OPTIONS"), whether or not then vested or exercisable, shall constitute the
right to receive an amount in cash equal to the positive difference, if any,
between (i) the product of the Exchange Ratio and the Average Share Price,
multiplied by the number of shares of Company Common Stock for which the Company
Stock Option was exercisable immediately prior to the Effective Time and (ii)
the aggregate exercise price of the Company Common Stock purchasable pursuant to
such Company Stock Option. Any Company Stock Option the exercise price of which
as of the Effective Time equals or exceeds the amount equal to the product of
the Exchange Ratio and the Average Share Price shall be cancelled and be of no
further force and effect as of the Effective Time.

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

    (e)  ADJUSTMENTS TO EXCHANGE RATIO.  The Exchange Ratio shall be
appropriately adjusted to reflect fully the effect of any stock split, reverse
split, stock dividend (including any dividend or distribution of securities
convertible into Guarantor Common Shares or Company Common Stock), distribution,
exercise or exchange of Rights (as defined in Section 4.02(d)) or such Rights
becoming exercisable, reorganization, recapitalization, split up, combination or
exchange of shares or other like event with respect to Guarantor Common Shares
or Company Common Stock occurring after the date hereof and prior to the
Effective Time.

    (f)  FRACTIONAL SHARES.  No certificates or scrip representing less than one
Guarantor Common Share shall be issued upon the surrender for exchange of a
certificate or certificates or other evidence for shares issued pursuant to the
Company's direct registration system which immediately prior to the Effective
Time represented outstanding Shares (the "CERTIFICATES"). In lieu of any such
fractional share, each holder of Shares who would otherwise have been entitled
to a fraction of a Guarantor Common Share upon surrender of Certificates for
exchange shall be paid upon such surrender cash (without

                                      A-3
<PAGE>
interest) in an amount equal to such fraction multiplied by the last reported
sale price per Guarantor Common Share on the NYSE Composite Transaction Tape on
the last trading day prior to the date of the Effective Time.

    SECTION 1.07.  EXCHANGE OF CERTIFICATES.  (a) EXCHANGE AGENT. Parent shall
cause to be supplied to or for such bank or trust company as shall be designated
by Parent and shall be reasonably acceptable to the Company (the "EXCHANGE
AGENT"), in trust for the benefit of the holders of Company Common Stock, as
needed for exchange in accordance with this Section 1.07 through the Exchange
Agent, certificates evidencing the Guarantor Common Shares issuable pursuant to
Section 1.06(a) and the cash to be paid in lieu of fractional shares in exchange
for outstanding Shares.

    (b)  EXCHANGE PROCEDURES.  As soon as reasonably practicable after the
Effective Time, Parent will cause the Exchange Agent to mail to each holder of
record of Certificates (i) a letter of transmittal (which shall specify that
delivery shall be effected, and risk of loss and title to the Certificates shall
pass, only upon proper delivery of the Certificates to the Exchange Agent and
shall be in such form and have such other provisions as Parent may reasonably
specify), and (ii) instructions to effect the surrender of the Certificates in
exchange for the certificates evidencing Guarantor Common Shares. Upon surrender
of a Certificate for cancellation to the Exchange Agent together with such
letter of transmittal, duly executed, and such other customary documents as may
be required pursuant to such instructions, the holder of such Certificate shall
be entitled to receive in exchange therefor solely (A) certificates evidencing
that number of whole Guarantor Common Shares which such holder has the right to
receive in accordance with the Exchange Ratio in respect of the Shares formerly
evidenced by such Certificate and (B) cash in respect of fractional shares as
provided in Section 1.06(f) (the Guarantor Common Shares and cash in respect of
fractional shares being, collectively, the "MERGER CONSIDERATION"). The holder
of such Certificate, upon its exchange for Guarantor Common Shares, shall also
receive any dividends or other distributions to which such holder is entitled
pursuant to Section 1.07(c). Certificates surrendered pursuant to this Section
1.07(b) shall forthwith be canceled. In the event of a transfer of ownership of
Shares which is not registered in the transfer records of the Company as of the
Effective Time, Merger Consideration, dividends or distributions may be issued
and paid in accordance with this Article I to a transferee if the Certificate
evidencing such Shares is presented to the Exchange Agent, accompanied by all
documents required to evidence and effect such transfer pursuant to this Section
1.07(b) and by evidence that any applicable stock transfer taxes have been paid.
Until so surrendered, each outstanding Certificate that, prior to the Effective
Time, represented Shares of Company Common Stock will be deemed from and after
the Effective Time, for all corporate purposes, other than the payment of
dividends or other distributions, to evidence the ownership of the number of
full Guarantor Common Shares, and cash in respect of fractional shares, into
which such Shares of Company Common Stock shall have been so converted.

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

    (d)  TRANSFERS OF OWNERSHIP.  If any certificate for Guarantor Common Shares
is to be issued in a name other than that in which the Certificate surrendered
in exchange therefor is registered, it will be a condition of the issuance
thereof that the Certificate so surrendered will be properly endorsed and
otherwise in proper form for transfer and that the person requesting such
exchange will have paid to Parent or any agent designated by it any transfer or
other taxes required by reason of the issuance of a

                                      A-4
<PAGE>
certificate for Guarantor Common Shares in any name other than that of the
registered holder of the certificate surrendered, or establish to the
satisfaction of Parent or any agent designated by it that such tax has been paid
or is not payable.

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

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

    (g)  UNDISTRIBUTED CERTIFICATES.  Any portion of the certificates evidencing
the Guarantor Common Shares and the cash to be paid in lieu of fractional shares
supplied to the Exchange Agent which remains undistributed to the holders of the
Certificates for one year after the Effective Time shall be delivered to Parent,
upon demand, and any holders of the Certificates who have not theretofore
complied with this Section 1.07 shall thereafter look only to Parent for payment
of their claim for Merger Consideration and any dividends or distributions with
respect to Guarantor Common Shares.

    SECTION 1.08.  DISSENTING SHARES.  Notwithstanding anything to the contrary
contained in this Agreement, any Shares outstanding immediately prior to the
Effective Time that were not voted in favor of the Merger and are held by
shareholders who have complied with the applicable provisions of Chapter 13 of
the CGCL (the "DISSENTING SHARES") shall not be converted into or represent the
right to receive Guarantor Common Shares in accordance with Section 1.06(a) (or
cash in lieu of fractional shares in accordance with Section 1.06(f)), and each
holder of Dissenting Shares shall be entitled only to such rights as may be
granted to such holder under Chapter 13 of the CGCL. From and after the
Effective Time, a holder of Dissenting Shares shall not have and shall not be
entitled to exercise any of the voting rights or other rights of a shareholder
of Guarantor. If any holder of Dissenting Shares shall fail to assert or
perfect, or shall waive, rescind, withdraw or otherwise lose, such holder's
right to dissent and obtain payment under Chapter 13 of the CGCL, then such
shares shall automatically be converted into and shall represent only the right
to receive (upon the surrender of the Certificate(s) previously representing
such Shares) Guarantor Common Shares in accordance with Section 1.06(f) (and
cash in lieu of any fractional share in accordance with Section 1.06(f)). In no
event shall Guarantor, Parent or any of their respective affiliates (other than
a subsidiary of the Company) reimburse the Company for any payment with respect
to the Dissenting Shares.

    SECTION 1.09.  STOCK TRANSFER BOOKS.  At the Effective Time, the stock
transfer books of the Company shall be closed, and there shall be no further
registration of transfers of the Company Common Stock thereafter on the records
of the Company.

    SECTION 1.10.  NO FURTHER OWNERSHIP RIGHTS IN COMPANY COMMON STOCK.  The
Merger Consideration delivered upon the surrender for exchange of Shares in
accordance with the terms hereof shall be deemed to have been issued in full
satisfaction of all rights pertaining to such Shares, and there shall be no
further registration of transfers on the records of the Surviving Corporation of
Shares which were outstanding immediately prior to the Effective Time. If, after
the Effective Time, Certificates are presented to the Surviving Corporation for
any reason, they shall be canceled and exchanged as provided in this Article I.

                                      A-5
<PAGE>
    SECTION 1.11.  LOST, STOLEN OR DESTROYED CERTIFICATES.  In the event any
Certificates shall have been lost, stolen or destroyed, the Exchange Agent shall
issue in exchange for such lost, stolen or destroyed Certificates, upon the
making of an affidavit of that fact by the holder thereof, such Guarantor Common
Shares as may be required pursuant to Section 1.06(a); PROVIDED, HOWEVER, that
Parent may, in its discretion and as a condition precedent to the issuance
thereof, require the owner of such lost, stolen or destroyed Certificates to
deliver a bond in such sum as it may reasonably direct as indemnity against any
claim that may be made against Guarantor, Parent or the Exchange Agent with
respect to the Certificates alleged to have been lost, stolen or destroyed.

    SECTION 1.12.  TAX CONSEQUENCES.  It is intended by the parties hereto that
the Merger shall constitute a reorganization within the meaning of Section 368
of the Code and the regulations promulgated thereunder. The parties hereto
hereby adopt this Agreement as a "plan of reorganization" within the meaning of
Sections 1.368-2(g) and 1.368-3(a) of the United States Treasury Regulations.

    SECTION 1.13.  TAKING OF NECESSARY ACTION; FURTHER ACTION.  Each of Parent,
Merger Sub and the Company will take all such reasonable and lawful actions as
may be necessary or appropriate in order to effectuate the Merger and the other
transactions contemplated by this Agreement in accordance with this Agreement as
promptly as possible. If, at any time after the Effective Time, any such further
action is necessary or desirable to carry out the purposes of this Agreement and
to vest the Surviving Corporation with full right, title and possession to all
assets, property, rights, privileges, powers and franchises of the Company and
Merger Sub, the officers and directors of the Company and Merger Sub immediately
prior to the Effective Time are fully authorized in the name of their respective
corporations or otherwise to take, and will take, all such lawful and necessary
action.

    SECTION 1.14.  MATERIAL ADVERSE EFFECT.  When used in connection with the
Company or any of its subsidiaries or Guarantor or any of its subsidiaries, as
the case may be, the term "MATERIAL ADVERSE EFFECT" means any change, effect or
circumstance that is or would reasonably be expected to be materially adverse to
the business, assets (including intangible assets), financial condition or
results of operations of the Company and its subsidiaries or Guarantor and its
subsidiaries, as the case may be, in each case taken as a whole; PROVIDED,
HOWEVER, that effects of changes that are applicable to (A) the United States
economy generally, (B) the United States securities markets generally, (C) the
healthcare or medical device industries generally, or (D) with respect to the
Company, changes or developments in any of the Company's pending litigation
matters set forth in Section 1.14 of the written disclosure schedule previously
delivered by the Company to Parent (the "COMPANY DISCLOSURE SCHEDULE") shall be
excluded from the definition of "Material Adverse Effect" and from any
determination as to whether a Material Adverse Effect has occurred or may occur.

                                   ARTICLE II
                 REPRESENTATIONS AND WARRANTIES OF THE COMPANY

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

    SECTION 2.01.  ORGANIZATION AND QUALIFICATION; SUBSIDIARIES.  Each of the
Company and its subsidiaries is a corporation duly organized, validly existing
and in good standing under the laws of the jurisdiction of its incorporation and
has the requisite corporate power and authority necessary to own, lease and
operate the properties it purports to own, operate or lease and to carry on its
business as it is now being conducted, except where the failure to be so
organized, existing and in good standing or to have such power or authority
would not reasonably be expected to have a Material Adverse Effect. Each of the
Company and its subsidiaries is duly qualified or licensed as a foreign
corporation to do business, and is in good standing, in each jurisdiction where
the character of its properties owned, leased or operated by it or the nature of
its activities makes such qualification or licensing necessary, except for such
failures to be so duly qualified or licensed and in good standing that would not
reasonably be expected to have a Material Adverse Effect. A true and complete
list of all of the

                                      A-6
<PAGE>
Company's "significant" subsidiaries, as defined in Regulation S-X, is included
as an exhibit to the Company's 1998 Annual Report on Form 10-K (the "COMPANY
SIGNIFICANT SUBSIDIARIES"). The Company has furnished or will furnish to Parent
a list of all subsidiaries of the Company together with the jurisdiction of
incorporation of each such subsidiary and the percentage of each such
subsidiary's outstanding capital stock owned by the Company or another
subsidiary of the Company in Section 2.01 of the Company Disclosure Schedule.
Except as set forth in Section 2.01 of the Company Disclosure Schedule or the
Company SEC Documents (as defined in Section 2.07 below), the Company does not
directly or indirectly own any equity or similar interest in, or any interest
convertible into or exchangeable or exercisable for, any equity or similar
interest in, any corporation, partnership, joint venture or other business
association or entity (other than its wholly-owned subsidiaries), with respect
to which interest the Company has invested (and currently owns) or is required
to invest $100,000 or more, excluding securities in any publicly-traded company
held for investment by the Company and comprising less than five percent of the
outstanding stock of such company.

    SECTION 2.02.  ARTICLES OF INCORPORATION AND BY-LAWS.  The Company has
heretofore made available to Parent a complete and correct copy of its Amended
and Restated Articles of Incorporation and By-laws as amended to date (the
"COMPANY CHARTER DOCUMENTS"), and will make available to Parent, as promptly as
practicable, the Articles of Incorporation and By-laws (or equivalent
organizational documents) of each of its subsidiaries reasonably requested by
Parent (the "SUBSIDIARY DOCUMENTS"). Such Company Charter Documents and
Subsidiary Documents are in full force and effect. Neither the Company nor any
of its subsidiaries is in violation of any of the provisions of its Articles of
Incorporation or By-laws or equivalent organizational documents, except for
violations of the documents which do not and are not reasonably likely to
materially interfere with the operations of such entity.

    SECTION 2.03.  CAPITALIZATION.  The authorized capital stock of the Company
consists of 50,000,000 shares of Company Common Stock and 2,000,000 shares of
preferred stock, par value $0.001 per share (the "COMPANY PREFERRED STOCK"). As
of July 31, 1999, (i) 13,546,347 shares of Company Common Stock were issued and
outstanding, all of which are validly issued, fully paid and nonassessable
(excluding shares which are issued but not outstanding all of which are not
entitled to vote), (ii) no shares of Company Common Stock were held by
subsidiaries of the Company, (iii) 2,115,838 shares of Company Common Stock were
reserved for existing grants and 780,531 shares were reserved for future grants
pursuant to (A) the Company's 1992 Stock Option Plan, as amended, (B) the
Company's 1995 Directors' Stock Option Plan, as amended, or (C) any other stock
option plan or agreement of the Company (collectively, the "COMPANY STOCK OPTION
PLANS"), and (iv) 204,873 shares of Company Common Stock were reserved and
available for future issuance pursuant to the Company's 1996 Employee Stock
Purchase Plan (the "COMPANY STOCK PURCHASE PLAN"). There are no outstanding
shares of Company Preferred Stock. Except as set forth in Section 2.03 of the
Company Disclosure Schedule, no change in such capitalization has occurred since
July 31, 1999, except for changes resulting from the exercise of Company Stock
Options. Except as set forth in Section 2.01, this Section 2.03 or Section 2.11
or in Section 2.03 or Section 2.11 of the Company Disclosure Schedule or the
Company SEC Documents, there are no options, warrants or other rights,
agreements, arrangements or commitments of any character binding on the Company
or any of its subsidiaries relating to the issued or unissued capital stock of
the Company or any of its subsidiaries or obligating the Company or any of its
subsidiaries to issue or sell any shares of capital stock of, or other equity
interests in, the Company or any of its subsidiaries. All shares of Company
Common Stock subject to issuance as aforesaid, upon issuance on the terms and
conditions specified in the instruments pursuant to which they are issuable,
shall be duly authorized, validly issued, fully-paid and nonassessable. Except
as disclosed in Section 2.03 of the Company Disclosure Schedule or the Company
SEC Documents, there are no obligations, contingent or otherwise, of the Company
or any of its subsidiaries to repurchase, redeem or otherwise acquire any shares
of Company Common Stock or the capital stock of any subsidiary. Except as
disclosed in Section 2.03 of the Company Disclosure Schedule or the

                                      A-7
<PAGE>
Company SEC Documents, there are no obligations, contingent or otherwise, of the
Company or any of its subsidiaries to provide funds to or make any investment
(in the form of a loan, capital contribution or otherwise) in any such
subsidiary or any other entity other than guarantees of bank obligations of
subsidiaries entered into in the ordinary course of business and other than
obligations in amounts less than $50,000 individually and $250,000 in the
aggregate. Except as set forth in Sections 2.01 and 2.03 of the Company
Disclosure Schedule, all of the outstanding shares of capital stock (other than
directors' qualifying shares) of each of the Company's subsidiaries are duly
authorized, validly issued, fully-paid and nonassessable, and all such shares
(other than directors' qualifying shares and a DE MINIMIS number of shares owned
by employees of such subsidiaries) are owned by the Company or another
subsidiary free and clear of all security interests, liens, claims, pledges,
agreements, limitations in the Company's voting rights, charges or other
encumbrances of any nature whatsoever.

    SECTION 2.04.  AUTHORITY RELATIVE TO THIS AGREEMENT.  The Company has all
necessary corporate power and authority to execute and deliver this Agreement
and to perform its obligations hereunder and to consummate the transactions
contemplated hereby. The execution and delivery of this Agreement by the Company
and the consummation by the Company of the transactions contemplated hereby have
been duly and validly authorized by all necessary corporate action, and no other
corporate proceedings on the part of the Company are necessary to authorize this
Agreement or to consummate the transactions so contemplated (other than the
approval of the Merger and this Agreement by the Company's shareholders in
accordance with the CGCL and the Company's Charter Documents). As of the date

the CGCL, and (c) unanimously recommended the adoption and approval of this
Agreement and the Merger by holders of the Company Common Stock and directed

Company's shareholders at the Company Shareholders Meeting. This Agreement has
been duly and validly executed and delivered by the Company and, assuming the
due authorization, execution and delivery by Guarantor, Parent and Merger Sub of
such agreement and/or the Guarantee thereof, as applicable, constitutes a legal,
valid and binding obligation of the Company.

    SECTION 2.05.  NO CONFLICT; REQUIRED FILINGS AND CONSENTS.  (a) Section
2.05(a) of the Company Disclosure Schedule includes, as of the date hereof, a
list of (i) other than intercompany, all loan agreements, indentures, mortgages,

to which the Company or any of its subsidiaries is a party or by which any of
them is bound; (ii) all contracts, agreements, commitments or other
understandings or arrangements to which the Company or any of its subsidiaries

assets are bound or affected, but excluding contracts, agreements, commitments
or other understandings or arrangements entered into in the ordinary course of
business and involving, in the case of any such contact, agreement, commitment,

amended, and the SEC's rules and regulations thereunder (the "EXCHANGE ACT") but
have not been so filed with the SEC.

    (b)  Except as set forth in Section 2.05(b) of the Company Disclosure
Schedule, the execution and delivery of this Agreement by the Company does not,
and the performance of this Agreement by the Company will not, (i) conflict with
or violate the Amended and Restated Articles of Incorporation or

                                      A-8
<PAGE>
By-laws of the Company, (ii) conflict with or violate any law, rule, regulation,
order, judgment or decree applicable to the Company or any of its subsidiaries
or by which its or any of their respective properties is bound or affected, or
(iii) result in any breach of or constitute a default (or an event that with
notice or lapse of time or both would become a default), or impair the Company's
or any of its subsidiaries' rights or alter the rights or obligations of any
third party under, or give to others any rights of termination, amendment,
acceleration or cancellation of, or result in the creation of a lien or
encumbrance on (including a right to purchase) any of the properties or assets
of the Company or any of its subsidiaries pursuant to, any note, bond, mortgage,
indenture, contract, agreement, lease, license, permit, franchise or other
instrument or obligation to which the Company or any of its subsidiaries is a
party or by which the Company or any of its subsidiaries or its or any of their
respective properties is bound or affected, except, in the case of clauses (ii)
or (iii), for any such conflicts, violations, breaches, defaults or other
occurrences that would not reasonably be expected, individually or in the
aggregate, to have a Material Adverse Effect.

    (c)  The execution and delivery of this Agreement by the Company does not,
and the performance of this Agreement by the Company will not, require any
consent, approval, authorization or permit of, or filing with or notification
to, any governmental or regulatory authority, domestic or foreign (each, a
"GOVERNMENTAL AUTHORITY"), except (i) for applicable requirements, if any, of
the Securities Act of 1933, as amended, and the rules and regulations of the
Securities and Exchange Commission ("SEC") thereunder (the "SECURITIES ACT"),

1976, as amended, and the rules and regulations thereunder (the "HSR ACT"),
filings and consents under any applicable foreign laws intended to prohibit,
restrict or regulate actions having the purpose or effect of monopolization or

the transactions contemplated by this Agreement, and the filing and recordation
of appropriate merger or other documents as required by the CGCL, (ii) where the
failure to obtain such consents, approvals, authorizations or permits, or to
make such filings or notifications, would not prevent or materially delay
consummation of the Merger, or otherwise prevent or materially delay the Company
from performing its material obligations under this Agreement, or would not
otherwise reasonably be expected, individually or in the aggregate, to have a
Material Adverse Effect, or (iii) as to which any necessary consents, approvals,
authorizations, permits, filings or notifications have heretofore been obtained
or filed, as the case may be, by the Company.

    SECTION 2.06.  COMPLIANCE; PERMITS.  (a) Except as disclosed in Section
2.06(a) of the Company Disclosure Schedule or the Company SEC Documents, neither
the Company nor any of its subsidiaries is in conflict with, or in default or

their respective properties is bound or affected or (ii) any note, bond,
mortgage, indenture, contract, agreement, lease, license, permit, franchise or
other instrument or obligation to which the Company or any of its subsidiaries
is a party or by which the Company or any of its subsidiaries or its or any of
their respective properties is bound or affected, except for any such conflicts,
defaults or violations which would not reasonably be expected, individually or
in the aggregate, to have a Material Adverse Effect.

    (b)  Except as disclosed in Section 2.06(b) of the Company Disclosure
Schedule or the Company SEC Documents, the Company and its subsidiaries hold all
permits, licenses, easements, variances, exemptions, consents, certificates,
orders and approvals from governmental authorities which are material to the
operation of the business of the Company and its subsidiaries taken as a whole
as it is now being conducted (collectively, the "COMPANY PERMITS"), except where
the failure to hold such Company Permits would not reasonably be expected,
individually or in the aggregate, to have a Material Adverse Effect. The Company
and its subsidiaries are in compliance with the terms of the

                                      A-9
<PAGE>
Company Permits, except as described in the Company SEC Documents or where the

material tax, penalty or other material liability for prohibited transactions
under ERISA or Section 4975 of the Code; (iv) no fiduciary of any Company
Employee Plan has breached any of the responsibilities or obligations imposed

Employee Plan that is subject to Title IV of ERISA (each, a "COMPANY DEFINED

any

                                      A-12
<PAGE>
extensions of any amortization period within the meaning of Section 412 of the
Code or Section 302 of ERISA been applied for with respect thereto; (iii) the
present value of the benefit liabilities (within the meaning of Section 4041 of
ERISA) of each Company Defined Benefit Plan, determined on an ongoing basis
using the actuarial assumptions used for funding purposes in the most recent
actuarial report prepared by each such plan's actuary with respect to that
plan's most recently completed fiscal year, does not exceed the value of that
Company Defined Benefit Plan's assets and to the knowledge of the Company,
nothing has occurred since the end of the most recently completed fiscal year
that would adversely affect the funding status of such plans; (iv) all
applicable premiums required to be paid to the PBGC with respect to the Company

    (f) Except as set forth in Section 2.11(f) of the Company Disclosure

    (g) The consummation of the transactions contemplated by this Agreement,
either alone or in combination with another event, will not result in (i) any
payment (including, without limitation, severance, unemployment compensation,
golden parachute or bonus payments or otherwise) becoming due to any current or
former director, officer, employee or consultant of the Company, (ii) any
increase in the amount of compensation or benefits payable in respect of any
director, officer, employee or consultant of the Company, (iii) accelerate the
vesting or timing of payment of any benefits or compensation payable in respect

with its terms and with the requirements prescribed by any and all applicable
laws (including any special provisions relating to registered or qualified plans
where such Non-U.S. Company Plan was intended to so qualify) and has been
maintained in good standing with applicable regulatory authorities. Except as
set forth on Section 2.11(h) of the Company Disclosure Schedule, the fair market
value of the assets of each funded Non-U.S. Company Plan, if any, (or the
liability of each funded Non-U.S. Company Plan funded through insurance) is

Effective Time according to the actuarial assumptions and valuations most
recently used to determine employer contributions to the Non-U.S. Company Plan.

investigation is in progress.

occupational health or safety legislation and to the best knowledge of the

effectiveness or the existence of such default or event of default would not
reasonably be expected, individually or in the aggregate, to have a Material
Adverse Effect.

    SECTION 4.02. NO SOLICITATION. (a) The Company shall not, directly or
indirectly, through any officer, director, employee, representative or agent of
the Company or any of its subsidiaries, solicit or encourage the initiation of
(including by way of furnishing information) any inquiries or proposals
regarding any merger, sale of assets, sale of shares of capital stock (including
without limitation by way of a tender offer) or similar transactions involving
the Company or any subsidiaries of the Company that if consummated would
constitute an Alternative Transaction (as defined in Section 7.01) (any of the
foregoing inquiries or proposals being referred to herein as an "ACQUISITION
PROPOSAL"). Nothing contained in this Agreement shall prevent the Board of
Directors of the Company from (i) furnishing information to a third party which
has made a BONA FIDE Acquisition Proposal that is a Superior Proposal (as
defined below) not solicited in violation of this Agreement, PROVIDED that such
third party has executed an agreement with confidentiality provisions
substantially similar to those then in effect between the Company and a
subsidiary of Guarantor or (ii) subject to compliance with the other terms of
this Section 4.02, including Sections 4.02(c) and (d), considering and
negotiating a bona fide Acquisition Proposal that is a Superior Proposal not
solicited in violation of this Agreement; PROVIDED, HOWEVER, that, as to each of
clauses (i) and (ii), (x) such actions occur at a time prior to approval of the
Merger and this Agreement at the Company Shareholders Meeting and (y) the Board
of Directors of the Company reasonably determines in good faith (after due
consultation with independent counsel, which may be Venture Law Group), that it
is or is reasonably likely to be required to do so in order to discharge
properly its fiduciary duties. For purposes of this Agreement, a "SUPERIOR
PROPOSAL" means any proposal made by a third party to acquire, directly or
indirectly, for consideration consisting of cash and/or securities, all of the
equity securities of the Company entitled to vote generally in the election of
directors or all or substantially all the assets of the Company, on terms which
the Board of Directors of the Company reasonably believes (i) (after
consultation with a financial advisor of nationally recognized reputation) to be
more favorable from a financial point of view to its shareholders than the
Merger and the transactions contemplated by this Agreement taking into account
at the time of determination any changes to the financial terms of this
Agreement proposed by Parent and (ii) to be more favorable to the Company than
the Merger and the transactions contemplated by this Agreement after taking into
account all pertinent factors deemed relevant by the Board of Directors of the
Company under the laws of the State of California; PROVIDED, HOWEVER, that a
Superior Proposal may be subject to a due diligence review of confidential
information and to other customary conditions.

    (b) The Company shall notify Parent promptly (but in no event later than 24
hours) after receipt of any Acquisition Proposal, or any modification of or
amendment to any Acquisition Proposal, or any request for nonpublic information
relating to the Company or any of its subsidiaries in connection with an
Acquisition Proposal or for access to the properties, books or records of the
Company or any subsidiary by any person or entity that informs the Board of
Directors of the Company or such subsidiary that it is considering making, or
has made, an Acquisition Proposal. Such notice to Parent shall be made orally
and in writing, and shall indicate the identity of the person making the
Acquisition

                                      A-26
<PAGE>
Proposal or intending to make an Acquisition Proposal or requesting non-public
information or access to the books and records of the Company, the terms of any
such Acquisition Proposal or modification or amendment to an Acquisition
Proposal, and whether the Company is providing or intends to provide the person
making the Acquisition Proposal with access to information concerning the
Company as provided in Section 4.02(a). The Company shall keep Parent fully
informed, on a current basis, of any material changes in the status and any
material changes or modifications in the material terms of any such Acquisition
Proposal, indication or request. The Company shall also immediately notify
Parent, orally and in writing, if it enters into negotiations concerning any
Acquisition Proposal.

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

    (d) The Company and the Board of Directors of the Company shall not (i)
redeem the rights (the "RIGHTS") issued under the Preferred Shares Rights
Agreement, dated as of May 9, 1997, as amended, between the Company and The U.S.
Stock Transfer Corporation, as Rights Agent (the "RIGHTS AGREEMENT"), or waive
or amend any provision of the Rights Agreement, in any such case to permit or
facilitate the consummation of any Acquisition Proposal or Alternative
Transaction, or (ii) enter into any agreement with respect to, or otherwise
approve or recommend, or propose to approve or recommend, any Acquisition
Proposal or Alternative Transaction, unless this Agreement has been terminated
in accordance with its terms. It is understood and agreed that a deferral of the
distribution of Rights following the commencement of a tender offer or exchange
offer shall not be prohibited hereunder.

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

    (f) The Company shall immediately cease and cause to be terminated any
existing discussions or negotiations with any persons (other than Parent and
Merger Sub) conducted heretofore with respect to any of the foregoing. The
Company agrees not to release any third party from the confidentiality and
standstill provisions of any agreement to which the Company is a party.

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

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

                                      A-27

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

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

        (c) declare, set aside, make or pay any dividend or other distribution
    (whether in cash, stock or property or any combination thereof) in respect
    of any of its capital stock, except that a wholly owned subsidiary of
    Guarantor may declare and pay a dividend to its parent, and except that
    Guarantor may effect a previously declared two-for-one stock split in the
    form of a stock dividend and may declare and pay quarterly cash dividends on
    the Guarantor Common Shares of $0.025 per share (on a pre-split basis)
    consistent with past practice;

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

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

                                   ARTICLE V
                             ADDITIONAL AGREEMENTS

    SECTION 5.01. PROXY STATEMENT/PROSPECTUS; REGISTRATION STATEMENT. As
promptly as practicable after the execution of this Agreement, the Company

thereon and after the furnishing by the Company and Guarantor of all information
required to be contained therein, the Company shall, and Parent shall cause
Guarantor to, file with the SEC the definitive Proxy Statement/Prospectus and

extent that the Board of Directors of the Company reasonably determines (after

                                      A-28
<PAGE>
due consultation with independent counsel, which may be Venture Law Group) that
it is or is reasonably likely that any such action is inconsistent with the
proper discharge of its fiduciary duties; PROVIDED, HOWEVER, that in no event
shall the Board of Directors recommend that the Company's shareholders vote
against approval of the Merger and adoption of this Agreement at the Company
Shareholders Meeting.

Parent shall take all action necessary such that Guarantor will make) all

modification is required after the Effective Time by law and then only to the
minimum extent required by such law.

                                      A-29
<PAGE>
    (b) The Surviving Corporation shall, to the fullest extent permitted under
applicable law or under the Surviving Corporation's Articles of Incorporation or
By-laws, indemnify and hold harmless, each present and former director, officer
or employee of the Company or any of its subsidiaries (collectively, the
"INDEMNIFIED PARTIES") against any costs or expenses (including attorneys'
fees), judgments, fines, losses, claims, damages, liabilities and amounts paid
in settlement in connection with any claim, action, suit, proceeding or
investigation, whether civil, criminal, administrative or investigative, (x)
arising out of or pertaining to the transactions contemplated by this Agreement
or (y) otherwise with respect to any acts or omissions occurring at or prior to
the Effective Time, to the same extent as provided in the Company's Amended and
Restated Articles of Incorporation or By-laws or any applicable contract or
agreement as in effect on the date hereof, in each case for a period of six
years after the Effective Time. In the event of any such claim, action, suit,
proceeding or investigation (whether arising before or after the Effective Time)
and subject to the specific terms of any indemnification contract, (i) any
counsel retained by the Indemnified Parties for any period after the Effective
Time shall be reasonably satisfactory to the Surviving Corporation, (ii) after
the Effective Time, the Surviving Corporation shall pay the reasonable fees and
expenses of such counsel, promptly after statements therefor are received and
(iii) the Surviving Corporation will cooperate in the defense of any such
matter; PROVIDED, HOWEVER, that the Surviving Corporation shall not be liable
for any settlement effected without its written consent (which consent shall not
be unreasonably withheld); and PROVIDED, FURTHER, that, in the event that any
claim or claims for indemnification are asserted or made within such six-year
period, all rights to indemnification in respect of any such claim or claims
shall continue until the disposition of any and all such claims. The Indemnified
Parties as a group may retain only one law firm to represent them in each
applicable jurisdiction with respect to any single action unless there is, under
applicable standards of professional conduct, a conflict on any significant
issue between the positions of any two or more Indemnified Parties, in which
case each Indemnified Person with respect to whom such a conflict exists (or
group of such Indemnified Persons who among them have no such conflict) may
retain one separate law firm in each applicable jurisdiction.

    (c) The Surviving Corporation shall honor and fulfill in all respects the
obligations of the Company pursuant to indemnification agreements and employment
agreements (the employee parties under such agreements being referred to as the
"OFFICER EMPLOYEES") with the Company's directors and officers existing at or
before the Effective Time.

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

    (e) From and after the Effective Time, Parent shall unconditionally
guarantee the timely payment of all funds owing by, and the timely performance
of all other obligations of, the Surviving Corporation under this Section 5.07.

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

    SECTION 5.07. NOTIFICATION OF CERTAIN MATTERS. The Company shall give prompt
notice to Parent, and Parent shall give prompt notice to the Company, of (i) the
occurrence or nonoccurrence of any event the occurrence or nonoccurrence of
which would reasonably be expected to cause any

                                      A-30
<PAGE>
representation or warranty contained in this Agreement to be materially untrue
or inaccurate, or (ii) any failure of the Company, Parent or Merger Sub, as the
case may be, materially to comply with or satisfy any covenant, condition or
agreement to be complied with or satisfied by it hereunder; PROVIDED, HOWEVER,
that the delivery of any notice pursuant to this Section shall not limit or
otherwise affect the remedies available hereunder to the party receiving such
notice; and PROVIDED FURTHER that failure to give such notice shall not be
treated as a breach of covenant for the purposes of Sections 6.02(b) or 6.03(b)
unless the failure to give such notice results in material prejudice to the
other party.

    SECTION 5.08. FURTHER ACTION/TAX TREATMENT. Upon the terms and subject to
the conditions hereof, each of the parties hereto shall use all reasonable
efforts to take, or cause to be taken, all actions and to do, or cause to be
done, all other things necessary, proper or advisable to consummate and make
effective as promptly as practicable the transactions contemplated by this
Agreement, to obtain in a timely manner all necessary waivers, consents and
approvals and to effect all necessary registrations and filings, and otherwise
to satisfy or cause to be satisfied all conditions precedent to its obligations
under this Agreement. The foregoing covenant shall not include any obligation by
Guarantor to agree to divest, abandon, license, enter into, modify, maintain or
renew any contract arrangement regarding or take similar action with respect to
any assets (tangible or intangible) of Guarantor or the Company or any of their
subsidiaries. Each of Parent, Merger Sub and the Company shall, and Parent shall
use its reasonable best efforts to cause Guarantor to, use its reasonable best
efforts to cause the Merger to qualify, and will not (either before or after
consummation of the Merger) take any actions, or fail to take any action, that
might reasonably be expected to prevent the Merger from qualifying as a
reorganization under the provisions of Section 368 of the Code that is not
subject to Section 367(a)(1) of the Code pursuant to Treasury Regulation Section
1.367(a)-(3)(c) (other than with respect to Company shareholders who are or will
be "5% transferee shareholders" within the meaning of Treasury Regulation
Section 1.367(a)-3(c)(5)(ii)). Parent shall, and shall use its reasonable best
efforts to cause the Surviving Corporation and Guarantor, to report, to the
extent required by the Code or the regulations thereunder, the Merger for United
States federal income tax purposes as a reorganization within the meaning of
Section 368 of the Code.

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

    SECTION 5.10. GUARANTOR COMMON SHARES. (a) Prior to the Effective Time,
Parent shall take all action necessary so that Guarantor shall transfer to
Parent the Guarantor Common Shares to be delivered by Parent to the holders of
Company Common Stock in the Merger.

    (b) Parent will take all action necessary so that Guarantor will use its
best efforts to cause the Guarantor Common Shares to be delivered by Parent to
the holders of Company Common Stock in the Merger to be listed, upon official
notice of issuance, on the NYSE prior to the Effective Time.

    SECTION 5.11. CONVEYANCE TAXES. Parent and the Company shall cooperate in
the preparation, execution and filing of all returns, questionnaires,
applications, or other documents regarding any real property transfer or gains,
sales, use, transfer, value added, stock transfer and stamp taxes, any transfer,
recording, registration and other fees, and any similar taxes which become
payable in connection with the transactions contemplated hereby that are
required or permitted to be filed on or before the Effective Time, and the
Company shall be responsible for the payment of all such taxes and fees. In no
event shall Parent or any affiliate thereof (other than a subsidiary of the
Company) reimburse the Company for the payment of such taxes and fees.

                                      A-31
<PAGE>

date of the then current offering period under the Company Stock Purchase Plan
to be prior to the Effective Time and to terminate such plan as of the Effective
Time.

take all further action (in addition to that referred to in Section 2.24), if
any, necessary in order to render the Rights inapplicable to the Merger and the
other transactions contemplated by this Agreement.

the Company shall use its best efforts to cause PricewaterhouseCoopers LLP to
deliver to Parent, and Parent shall use its best efforts to cause
PricewaterhouseCoopers LLP to deliver to the Company, a letter covering such
matters as are reasonably requested by Parent or the Company, as the case may

shareholders of the Company:

        (a) by mutual written consent duly authorized by the Boards of Directors

                                      A-34
<PAGE>
    the right to terminate this Agreement under this Section 7.01(b) shall not
    be available to any party whose failure to fulfill any obligation under this
    agreement has been the cause of, or resulted in, the failure of the Merger
    to be consummated on or prior to such date; or

    or governmental, regulatory or administrative agency or commission shall

    Misrepresentation is curable prior to February 28, 2000 by the Company or
    Parent, as the case may be, through the exercise of its reasonable best
    efforts and for so long as the Company or Parent, as the case may be,
    continues to exercise such reasonable best efforts, neither Parent nor the
    Company, respectively, may terminate this Agreement under this Section
    7.01(f); or

    Breach (as hereinafter defined); PROVIDED that if any such Terminating
    Change is curable prior to February 28, 2000 by the Company or Parent, as
    the case may be, through the exercise of its reasonable best efforts, and
    for so long as the Company or Parent, as the case may be, continues to

    respectively, may terminate this Agreement under this Section 7.01(g); or

        (h) by Parent or the Company, upon a breach of any covenant or agreement
    on the part of the Company or Parent, respectively, set forth in this
    Agreement such that the conditions set forth in Sections 6.02(b) or 6.03(b),
    as the case may be, would not be satisfied (a "TERMINATING BREACH");
    PROVIDED that, except for any breach of the Company's obligations under
    Section 4.02, if such Terminating Breach is curable prior to February 28,
    2000 by the Company or Parent, as the case may be, through the exercise of
    its reasonable best efforts and for so long as the Company or Parent, as the

    Company shall have notified Parent in writing that it intends to enter into
    such an agreement, attaching a summary of the material terms thereof, (x)
    Parent shall not have made, within two full business days (disregarding any
    partial business days) of receipt of the Company's written notification of
    its intention to enter into a definitive agreement with respect to a
    Superior Proposal, an offer that the Board of Directors of the Company
    determines, in good faith after consultation with its financial advisors, is
    at least as favorable, from a financial point of view, to the shareholders
    of the Company as the Superior Proposal, (y) the Company prior to such
    termination pursuant to this clause (i) shall have paid to Parent in
    immediately available funds the Fee and the Expenses required to be paid
    pursuant to Section 7.03(b), and (z) this Agreement shall not theretofore

(ii) a merger or other business combination involving the Company pursuant to
which any Third Party acquires more than 30% of the outstanding equity

subsidiaries) of the Company, or any of its subsidiaries having a fair market
value (as determined by the Board of Directors of the Company in good faith)
equal to more than 30% of the fair market value of all the assets of the Company
and its subsidiaries, taken as a whole, immediately prior to such transaction,
or (iv) any other consolidation, business combination, recapitalization or
similar transaction involving the Company or any of the Company Significant
Subsidiaries, other than the transactions contemplated by this Agreement;
PROVIDED, HOWEVER, that the term Alternative Transaction shall not include any
acquisition of securities by a broker dealer in connection with a bona fide
public offering of such securities.

affiliates, directors, officers or shareholders (i) except that the Company or
Parent or Merger Sub may have liability as set forth in Section 7.03 and Section
8.01 hereof, and (ii) nothing herein shall relieve the Company, Parent or Merger
Sub from liability for any willful material breach hereof (it being understood
that the mere existence of a Material Adverse Effect, by itself, shall not
constitute such a willful material breach).

    SECTION 7.03. FEES AND EXPENSES. (a) Except as set forth in this Section
7.03, all fees and expenses incurred in connection with this Agreement and the
transactions contemplated hereby shall be paid by the party incurring such

reference purposes only and shall not affect in any way the meaning or
interpretation of this Agreement.

    SECTION 8.07. SEVERABILITY. (a) If any term or other provision of this
Agreement is invalid, illegal or incapable of being enforced by any rule of law
or public policy, all other conditions and provisions of this Agreement shall
nevertheless remain in full force and effect so long as the economic or legal
substance of the transactions contemplated hereby is not affected in any manner
adverse to any party. Upon a determination that any term or other provision is
invalid, illegal or incapable of being enforced, the parties hereto shall
negotiate in good faith to modify this Agreement so as to effect the original

that transactions contemplated hereby are fulfilled to the extent possible.

7.03(b) is fair and reasonable in the circumstances. If a court of competent

circumstances, as determined by such court of competent jurisdiction.

    SECTION 8.08. ENTIRE AGREEMENT. This Agreement, the Guarantor's guarantees
thereof and the Voting Agreement constitute the entire agreement and supersede

and thereof, except as otherwise expressly provided herein or therein.

of law or otherwise, except that all or any of the rights of Parent and/or
Merger Sub hereunder may be assigned to Guarantor or any direct or indirect
wholly-owned subsidiary of Guarantor provided that no such assignment shall
relieve the assigning party of its obligations hereunder.

    SECTION 8.10. PARTIES IN INTEREST. This Agreement shall be binding upon and
inure solely to the benefit of each party hereto, and nothing in this Agreement,
express or implied, is intended to or shall confer upon any other person any
right, benefit or remedy of any nature whatsoever under or by reason of this
Agreement, including, without limitation, by way of subrogation, other than
Section 5.06 (which is intended to be for the benefit of the Indemnified Parties
and Officer Employees and may be enforced by such Indemnified Parties and
Officer Employees) and Section 7.03 (which contains provisions intended to be
for the benefit of Guarantor and may be enforced by Guarantor).

    SECTION 8.11. FAILURE OR INDULGENCE NOT WAIVER; REMEDIES CUMULATIVE. No
failure or delay on the part of any party hereto in the exercise of any right
hereunder shall impair such right or be construed to be a waiver of, or
acquiescence in, any breach of any representation, warranty or agreement herein,
nor shall any single or partial exercise of any such right preclude other or
further exercise thereof or of any other right. All rights and remedies existing
under this Agreement are cumulative to, and not exclusive of, any rights or
remedies otherwise available.

COMPANY HEREBY IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY LAW, ALL

                                   GUARANTEE

    Tyco International Ltd. ("GUARANTOR") guarantees each and every
representation, warranty, covenant, agreement and other obligation of Parent and
Merger Sub, and/or any of their respective permitted assigns (and where any such
representation or warranty is made to the knowledge of Parent or Merger Sub,
such guarantee shall be deemed made to the knowledge of Guarantor), and the full
and timely performance of their respective obligations under the provisions of
the foregoing Agreement. This is a guarantee of payment and performance, and not
of collection, and Guarantor acknowledges and agrees that this guarantee is
unconditional, and no release or extinguishment of Parent's and Merger Sub's
obligations or liabilities (other than in accordance with the terms of the
Agreement), whether by decree in any bankruptcy proceeding or otherwise, shall
affect the continuing validity and enforceability of this guarantee, as well as
any provision requiring or contemplating performance by Guarantor.

    Without limiting in any way the foregoing guarantee, Guarantor covenants and
agrees to take all actions to enable Parent to adhere to the provisions of
Sections 1.06, 5.01 and 5.10 of the Agreement.

    The provisions of ARTICLE VIII of the Agreement are incorporated herein,
MUTATIS MUTANDIS, except that notices and other communications hereunder to
Guarantor shall be delivered to Tyco International Ltd., The Gibbons Building,
10 Queen Street, Suite 301, Hamilton HM 11 Bermuda, Attn: Secretary, Telecopy
No. (441) 295-9647, Confirm No. (441) 292-8674 (with a copy as provided therefor
in Section 8.02(a)).

    We understand that the Company is relying on this guarantee in entering into
the Agreement and may enforce this guarantee as if Guarantor were a party
thereto.

Board of Directors
General Surgical Innovations, Inc.
10460 Bubb Road
Cupertino, CA 95014

Gentlemen:

    We understand that General Surgical Innovations, Inc. ("GSI" or the
"Company"), General Acquisition Corp. ("Parent"), a direct wholly-owned
subsidiary of Tyco International Ltd. ("Guarantor" or "Tyco"), and General Sub
Acquisition Corp., a direct wholly-owned subsidiary of Parent ("Merger Sub"),
have entered into an Agreement and Plan of Merger (the "Agreement") dated as of
August 23, 1999, pursuant to which, and subject to certain conditions precedent,
the Merger Sub shall be merged with and into the Company, and each share of
issued and outstanding capital stock of GSI will be converted into the right to
receive from Parent a fraction of a Tyco share equal to $7.50 divided by the
price of Tyco's shares over a certain period of time (the "Average Share Price")
prior to the Company's Shareholders Meeting, subject to certain potential
adjustments (the "Proposed Transaction"). The terms and conditions of the
Proposed Transaction are set forth in more detail in the Agreement.

    You have requested our opinion, as investment bankers, as to the fairness,
from a financial point of view, to the shareholders of GSI of the consideration
to be received in the Proposed Transaction.

    We have acted as financial advisor to the Board of Directors of the Company
in connection with the Proposed Transaction and will receive a fee for our
services. As you are aware, ING Barings LLC ("ING Barings") is a full service
securities firm that engages in securities trading and brokerage activities, in
addition to providing investment banking services. In the ordinary course of its
business, ING Barings, as a market maker or otherwise, may trade or otherwise
effect transactions in the securities of the Company and, accordingly, may at
any time hold a long or short position in such securities.

    In conducting our analysis and arriving at our opinion as expressed herein,
we have reviewed and analyzed, among other things, the following:

    (i) the Agreement and certain related documents and the financial terms of
the Proposed Transaction set forth therein;

    (ii) the Company's Annual Report on Form 10-K for the fiscal year ended June
30, 1998, the Company's Quarterly Report on Form 10-Q for the quarter ended
March 31, 1999, and the Company's earnings announcement for the year ended June
30, 1999;

    (v) certain other publicly available information concerning Tyco and the
trading market for Tyco's Common Stock;

    (vi) certain non-public information and other data related to the Company,
its business and prospects, including forecasts and projections, provided to us
by management of the Company;

    (vii) certain publicly available information concerning certain other
companies engaged in businesses which we believe to be generally comparable to
the Company and the trading markets for certain of such other companies'
securities;

    (viii) the financial terms of certain recent business combinations which we
believe to be relevant; and

    (ix) certain discussions and negotiations among representatives of the
Company and Tyco.

    We have also met with certain officers and employees of the Company
concerning its business and operations, assets, present condition and prospects
and undertook such other studies, analyses and investigations as we deemed
appropriate.

    In arriving at our opinion, we have assumed and relied upon the accuracy and
completeness of the financial and other information used by us and have not
attempted independently to verify such information, nor do we assume any
responsibility to do so. We have assumed that the Company's forecasts and
projections provided to or reviewed by us have been reasonable prepared based on
the best current estimates and judgment of the Company's management as to the
future financial condition and results of operations of the Company. We have
visited but have not conducted a physical inspection of the properties and
facilities of the Company, nor have we made or obtained any independent
evaluation or appraisal of such properties and facilities. We have also taken
into account our assessment of general economic, market and financial conditions
and our experience in similar transactions, as well as our experience in
securities valuation in general. Our opinion necessarily is based upon economic,
market, financial and other conditions as they exist and can be evaluated on the
date hereof and we assume no responsibility to update or revise our opinion
based upon events or circumstances occurring after the date hereof. We reserve,
however, the right to withdraw, revise or modify our opinion based upon
additional information which may be provided to or obtained by us, which
suggests, in our judgment, a material change in the assumptions upon which our
opinion is based.

    This letter and the opinion expressed herein are for the use of the Board of
Directors of the Company. This opinion does not address the Company's underlying
business decision to approve the Proposed Transaction or constitute a
recommendation to the shareholders of the Company as to how such shareholders
should vote or as to any other action such shareholders should take regarding
the Proposed Transaction. This opinion may not be reproduced, summarized,
excerpted from or otherwise publicly referred to or disclosed in any manner
without our prior written consent, except the Company may include this opinion
in its entirety in any proxy statement or information statement relating to the
transaction sent to the Company's shareholders.

    Based upon and subject to the foregoing, it is our opinion as investment
bankers that the consideration to be received by the shareholders of the Company
in the Proposed Transaction is fair, from a financial point of view, to such
shareholders.

                                          Very truly yours,

                       CALIFORNIA GENERAL CORPORATION LAW
                         CHAPTER 13--DISSENTERS' RIGHTS

Section 1300.  (a) If the approval of the outstanding shares (Section 152) of a
corporation is required for a reorganization under subdivisions (a) and (b) or
subdivision (e) or (f) of Section 1201, each shareholder of the corporation
entitled to vote on the transaction and each shareholder of a subsidiary
corporation in a short-form merger may, by complying with this chapter, require
the corporation in which the shareholder holds shares to purchase for cash at
their fair market value the shares owned by the shareholder which are dissenting
shares as defined in subdivision (b). The fair market value shall be determined
as of the day before the first announcement of the terms of the proposed
reorganization or short-form merger, excluding any appreciation or depreciation
in consequence of the proposed action, but adjusted for any stock split, reverse
stock split, or share dividend which becomes effective thereafter.

    (b)  As used in this chapter, "dissenting shares" means shares which come
within all of the following descriptions:

        (1)  Which were not immediately prior to the reorganization or
short-form merger either (A) listed on any national securities exchange
certified by the Commissioner of Corporations under subdivision (o) of Section
25100 or (B) listed on the list of OTC margin stocks issued by the Board of
Governors of the Federal Reserve System, and the notice of meeting of
shareholders to act upon the reorganization summarizes this section and Sections
1301, 1302, 1303 and 1304; provided, however, that this provision does not apply
to any shares with respect to which there exists any restriction on transfer
imposed by the corporation or by any law or regulation; and provided, further,
that this provision does not apply to any class of shares described in
subparagraph (A) or (B) if demands for payment are filed with respect to 5
percent or more of the outstanding shares of that class.

        (2)  Which were outstanding on the date for the determination of
shareholders entitled to vote on the reorganization and (A) were not voted in
favor of the reorganization or, (B) if described in subparagraph (A) or (B) of
paragraph (1) (without regard to the provisos in that paragraph), were voted
against the reorganization, or which were held of record on the effective date
of a short-form merger; provided, however, that subparagraph (A) rather than
subparagraph (B) of this paragraph applies in any case where the approval
required by Section 1201 is sought by written consent rather than at a meeting.

        (3)  Which the dissenting shareholder has demanded that the corporation
purchase at their fair market value, in accordance with Section 1301.

        (4)  Which the dissenting shareholder has submitted for endorsement, in
accordance with Section 1302.

    (c)  As used in this chapter, "dissenting shareholder" means the
recordholder of dissenting shares and includes a transferee of record.

Section 1301. (a) If, in the case of a reorganization, any shareholders of a
corporation have a right under Section 1300, subject to compliance with
paragraphs (3) and (4) of subdivision (b) thereof, to require the corporation to
purchase their shares for cash, such corporation shall mail to each such
shareholder a notice of the approval of the reorganization by its outstanding
shares (Section 152) within 10 days after the date of such approval, accompanied
by a copy of Sections 1300, 1302, 1303, 1304 and this section, a statement of
the price determined by the corporation to represent the fair market value of
the dissenting shares, and a brief description of the procedure to be followed
if the shareholder desires to exercise the shareholder's right under such
sections. The statement of price

                                      C-1
<PAGE>
constitutes an offer by the corporation to purchase at the price stated any
dissenting shares as defined in subdivision (b) of Section 1300, unless they
lose their status as dissenting shares under Section 1309.

    (b)  Any shareholder who has a right to require the corporation to purchase
the shareholder's shares for cash under Section 1300, subject to compliance with
paragraphs (3) and (4) of subdivision (b) thereof, and who desires the
corporation to purchase such shares shall make written demand upon the
corporation for the purchase of such shares and payment to the shareholder in
cash of their fair market value. The demand is not effective for any purpose
unless it is received by the corporation or any transfer agent thereof (1) in
the case of shares described in clause (i) or (ii) of paragraph (1) of
subdivision (b) of Section 1300 (without regard to the provisos in that
paragraph), not later than the date of the shareholders' meeting to vote upon
the reorganization, or (2) in any other case within 30 days after the date on
which the notice of the approval by the outstanding shares pursuant to
subdivision (a) or the notice pursuant to subdivision (i) of Section 1110 was
mailed to the shareholder.

    (c)  The demand shall state the number and class of the shares held of
record by the shareholder which the shareholder demands that the corporation
purchase and shall contain a statement of what such shareholder claims to be the
fair market value of those shares as of the day before the announcement of the
proposed reorganization or short-form merger. The statement of fair market value
constitutes an offer by the shareholder to sell the shares at such price.

Section 1302. Within 30 days after the date on which notice of the approval by
the outstanding shares or the notice pursuant to subdivision (i) of Section 1110
was mailed to the shareholder, the shareholder shall submit to the corporation
at its principal office or at the office of any transfer agent thereof, (a) if
the shares are certificated securities, the shareholder's certificates
representing any shares which the shareholder demands that the corporation
purchase, to be stamped or endorsed with a statement that the shares are
dissenting shares or to be exchanged for certificates of appropriate
denomination so stamped or endorsed or (b) if the shares are uncertificated
securities, written notice of the number of shares which the shareholder demands
that the corporation purchase. Upon subsequent transfers of the dissenting
shares on the books of the corporation, the new certificates, initial
transaction statement, and other written statements issued therefor shall bear a
like statement, together with the name of the original dissenting holder of the
shares.

Section 1303. (a) If the corporation and the shareholder agree that the shares
are dissenting shares and agree upon the price of the shares, the dissenting
shareholder is entitled to the agreed price with interest thereon at the legal
rate on judgments from the date of the agreement. Any agreements fixing the fair
market value of any dissenting shares as between the corporation and the holders
thereof shall be filed with the secretary of the corporation.

    (b)  Subject to the provisions of Section 1306, payment of the fair market
value of dissenting shares shall be made within 30 days after the amount thereof
has been agreed or within 30 days after any statutory or contractual conditions
to the reorganization are satisfied, whichever is later, and in the case of
certificated securities, subject to surrender of the certificates therefor,
unless provided otherwise by agreement.

Section 1304. (a) If the corporation denies that the shares are dissenting
shares, or the corporation and the shareholder fail to agree upon the fair
market value of the shares, then the shareholder demanding purchase of such
shares as dissenting shares or any interested corporation, within six months
after the date on which notice of the approval by the outstanding shares
(Section 152) or notice pursuant to subdivision (i) of Section 1110 was mailed
to the shareholder, but not thereafter, may file a complaint in the superior
court of the proper county praying the court to determine whether the shares are
dissenting shares or the fair market value of the dissenting shares or both or
may intervene in any action pending on such a complaint.

                                      C-2
<PAGE>
    (b)  Two or more dissenting shareholders may join as plaintiffs or be joined
as defendants in any such action and two or more such actions may be
consolidated.

    (c)  On the trial of the action, the court shall determine the issues. If
the status of the shares as dissenting shares is in issue, the court shall first
determine that issue. If the fair market value of the dissenting shares is in
issue, the court shall determine, or shall appoint one or more impartial
appraisers to determine, the fair market value of the shares.

Section 1305. (a) If the court appoints an appraiser or appraisers, they shall
proceed forthwith to determine the fair market value per share. Within the time
fixed by the court, the appraisers, or a majority of them, shall make and file a
report in the office of the clerk of the court. Thereupon, on the motion of any
party, the report shall be submitted to the court and considered on such
evidence as the court considers relevant. If the court finds the report
reasonable, the court may confirm it.

    (b)  If a majority of the appraisers appointed fail to make and file a
report within 10 days from the date of their appointment or within such further
time as may be allowed by the court or the report is not confirmed by the court,
the court shall determine the fair market value of the dissenting shares.

    (c)  Subject to the provisions of Section 1306, judgment shall be rendered
against the corporation for payment of an amount equal to the fair market value
of each dissenting share multiplied by the number of dissenting shares which any
dissenting shareholder who is a party, or who has intervened, is entitled to
require the corporation to purchase, with interest thereon at the legal rate
from the date on which judgment was entered.

    (d)  Any such judgment shall be payable forthwith with respect to
uncertificated securities and, with respect to certificated securities, only
upon the endorsement and delivery to the corporation of the certificates for the
shares described in the judgment. Any party may appeal from the judgment.

    (e)  The costs of the action, including reasonable compensation to the
appraisers to be fixed by the court, shall be assessed or apportioned as the
court considers equitable, but, if the appraisal exceeds the price offered by
the corporation, the corporation shall pay the costs (including in the
discretion of the court attorneys' fees, fees of expert witnesses and interest
at the legal rate on judgments from the date of compliance with Sections 1300,
1301 and 1302 if the value awarded by the court for the shares is more than 125
percent of the price offered by the corporation under subdivision (a) of Section
1301).

Section 1306. To the extent that the provisions of Chapter 5 prevent the payment
to any holders of dissenting shares of their fair market value, they shall
become creditors of the corporation for the amount thereof together with
interest at the legal rate on judgments until the date of payment, but
subordinate to all other creditors in any liquidation proceeding, such debt to
be payable when permissible under the provisions of Chapter 5.

Section 1307. Cash dividends declared and paid by the corporation upon the
dissenting shares after the date of approval of the reorganization by the
outstanding shares (Section 152) and prior to payment for the shares by the
corporation shall be credited against the total amount to be paid by the
corporation therefor.

Section 1308. Except as expressly limited in this chapter, holders of dissenting
shares continue to have all the rights and privileges incident to their shares,
until the fair market value of their shares is agreed upon or determined. A
dissenting shareholder may not withdraw a demand for payment unless the
corporation consents thereto.

<PAGE>
Section 1309. Dissenting shares lose their status as dissenting shares and the
holders thereof cease to be dissenting shareholders and cease to be entitled to
require the corporation to purchase their shares upon the happening of any of
the following:

    (a)  The corporation abandons the reorganization. Upon abandonment of the
reorganization, the corporation shall pay on demand to any dissenting
shareholder who has initiated proceedings in good faith under this chapter all
necessary expenses incurred in such proceedings and reasonable attorneys' fees.

    (b)  The shares are transferred prior to their submission for endorsement in
accordance with Section 1302 or are surrendered for conversion into shares of
another class in accordance with the articles.

    (c)  The dissenting shareholder and the corporation do not agree upon the
status of the shares as dissenting shares or upon the purchase price of the
shares, and neither files a complaint or intervenes in a pending action as
provided in Section 1304, within six months after the date on which notice of
the approval by the outstanding shares or notice pursuant to subdivision (i) of
Section 1110 was mailed to the shareholder.

    (d)  The dissenting shareholder, with the consent of the corporation,
withdraws the shareholder's demand for purchase of the dissenting shares.

Section 1310. If litigation is instituted to test the sufficiency or regularity
of the votes of the shareholders in authorizing a reorganization, any
proceedings under Sections 1304 and 1305 shall be suspended until final
determination of such litigation.

Section 1311. This chapter, except Section 1312, does not apply to classes of
shares whose terms and provisions specifically set forth the amount to be paid
in respect to such shares in the event of a reorganization or merger.

Section 1312. (a) No shareholder of a corporation who has a right under this
chapter to demand payment of cash for the shares held by the shareholder shall
have any right at law or in equity to attack the validity of the reorganization
or short-form merger, or to have the reorganization or short-form merger set
aside or rescinded, except in an action to test whether the number of shares
required to authorize or approve the reorganization have been legally voted in
favor thereof; but any holder of shares of a class whose terms and provisions
specifically set forth the amount to be paid in respect to them in the event of
a reorganization or short-form merger is entitled to payment in accordance with
those terms and provisions or, if the principal terms of the reorganization are
approved pursuant to subdivision (b) of Section 1202, is entitled to payment in
accordance with the terms and provisions of the approved reorganization.

    (b)  If one of the parties to a reorganization or short-form merger is
directly or indirectly controlled by, or under common control with, another
party to the reorganization or short-form merger, subdivision (a) shall not
apply to any shareholder of such party who has not demanded payment of cash for
such shareholder's shares pursuant to this chapter; but if the shareholder
institutes any action to attack the validity of the reorganization or short-form
merger or to have the reorganization or short-form merger set aside or
rescinded, the shareholder shall not thereafter have any right to demand payment
of cash for the shareholder's shares pursuant to this chapter. The court in any
action attacking the validity of the reorganization or short-form merger or to
have the reorganization or short-form merger set aside or rescinded shall not
restrain or enjoin the consummation of the transaction except upon 10 days'
prior notice to the corporation and upon a determination by the court that
clearly no other remedy will adequately protect the complaining shareholder or
the class of shareholders of which such shareholder is a member.

    (c)  If one of the parties to a reorganization or short-form merger is
directly or indirectly controlled by, or under common control with, another
party to the reorganization or short-form merger, in any action to attack the
validity of the reorganization or short-form merger or to have the
reorganization or short-form merger set aside or rescinded, (1) a party to a
reorganization or short-form merger which controls another party to the
reorganization or short-form merger shall have the burden of proving that the
transaction is just and reasonable as to the shareholders of the controlled
party, and (2) a person who controls two or more parties to a reorganization
shall have the burden of proving that the transaction is just and reasonable as
to the shareholders of any party so controlled.

                 PART II INFORMATION NOT REQUIRED IN PROSPECTUS

ITEM 20. INDEMNIFICATION OF DIRECTORS AND OFFICERS

    Bye-Law 102 of the Tyco Bye-Laws provides, in part, that Tyco shall
indemnify its directors and other officers for all costs, losses and expenses
which they may incur in the performance of their duties as director or officer,
provided that such indemnification is not otherwise prohibited under the
Companies Act 1981 of Bermuda. Section 98 of the Companies Act 1981 prohibits
such indemnification against any liability arising out of the fraud or
dishonesty of the director or officer. However, such section permits Tyco to
indemnify a director or officer against any liability incurred by him in
defending any proceedings, whether civil or criminal, in which judgment is given
in his favor or in which he is acquitted or when other similar relief is granted
to him.

    The Registrant maintains $100,000,000 of insurance to reimburse the
directors and officers of Tyco and its subsidiaries for charges and expenses
incurred by them for wrongful acts claimed against them by reason of their being
or having been directors or officers of the Registrant or any subsidiary
thereof. Such insurance specifically excludes reimbursement of any director or
officer for any charge or expense incurred in connection with various designated
matters, including libel or slander, illegally obtained personal profits,
profits recovered by the Registrant pursuant to Section 16(b) of the Exchange
Act and deliberate dishonesty.

ITEM 22. UNDERTAKINGS

    The undersigned Registrant hereby undertakes:

        (1) To file, during any period in which offers or sales are being made,
    a post-effective amendment to this Registration Statement:

           (i) To include any prospectus required by Section 10(a)(3) of the
       Securities Act of 1933;

           (ii) To reflect in the prospectus any facts or events arising after
       the effective date of this Registration Statement (or most recent
       post-effective amendment thereof) which, individually or in the
       aggregate, represent a fundamental change in the information set forth in
       this Registration Statement. Notwithstanding the foregoing, any increase
       or decrease in volume of securities offered (if the total dollar value of
       securities offered would not exceed that which was registered) and any
       deviation from the maximum aggregate offering price may be reflected in
       the form of prospectus filed with the SEC pursuant to Rule 424(b) under
       the Securities Act, if in the aggregate, the changes in volume and price
       represent no more than a 20% change in the maximum aggregate offering
       price set forth in the "Calculation of Registration Fee" table in the
       effective registration statement; and

           (iii) To include any material information with respect to the plan of
       distribution not previously disclosed in this Registration Statement or
       any material change to such information in this Registration Statement;

        (2) That, for the purposes of determining any liability under the
    Securities Act of 1933, each such post-effective amendment shall be deemed
    to be a new registration statement relating to the securities offered
    therein, and the offering of such securities at that time shall be deemed to
    be the initial BONA FIDE offering thereof; and

        (3) To remove from registration by means of a post-effective amendment
    any of the securities being registered which remain unsold at the
    termination of the offering.

    The Registrant undertakes that, for purposes of determining any liability
under the Securities Act, each filing of the Registrant's annual report pursuant
to Section 13(a) or 15(d) of the Exchange Act (and, where applicable, each
filing of an employee benefit plan's annual report pursuant to Section 15(d) of
the Exchange Act) that is incorporated by reference in the Registration
Statement shall be deemed to be a new Registration Statement relating to the
securities offered therein, and the offering of such securities at that time
shall be deemed to be the initial BONA FIDE offering thereof.

    The Registrant undertakes that prior to any public reoffering of the
securities registered hereunder through use of a prospectus which is a part of
this Registration Statement, by any person or party who is deemed to be an
underwriter within the meaning of Rule 145(c), the issuer undertakes that such
reoffering prospectus will contain the information called for by the applicable
registration form with respect to reofferings by persons who may be deemed
underwriters, in addition to the information called for by the other items of
the applicable form.

    The Registrant undertakes that every prospectus: (i) that is filed pursuant
to the paragraph immediately preceding, or (ii) that purports to meet the
requirements of Section 10(a)(3) of the Securities Act and is used in connection
with an offering of securities subject to Rule 415, will be filed as a part of
an amendment to the Registration Statement and will not be used until such
amendment is effective, and that, for purposes of determining any liability
under the Securities Act, each such

                                      II-2
<PAGE>
post-effective amendment shall be deemed to be a new Registration Statement
relating to the securities offered therein, and the offering of such securities
at that time shall be deemed to be the initial BONA FIDE offering thereof.

    Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the foregoing provisions, or otherwise, the Registrant
has been advised that in the opinion of the SEC such indemnification is against
public policy as expressed in the Securities Act and is, therefore,
unenforceable. In the event that a claim for indemnification against such
liabilities (other than the payment by the Registrant of expenses incurred or
paid by a director, officer or controlling person of the Registrant in the
successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the Registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Securities Act and will be governed by the final
adjudication of such issue.

    The undersigned Registrant hereby undertakes that: (1) for purposes of
determining any liability under the Securities Act of 1933, the information
omitted from the form of prospectus filed as part of this Registration Statement
in reliance upon Rule 430A and contained in a form of prospectus filed by the
Registrant pursuant to Rule 424(b)(1) or (4) or 497(h) under the Securities Act
shall be deemed to be part of this Registration Statement as of the time it was
declared effective; and (2) for the purpose of determining any liability under
the Securities Act of 1933, each post-effective amendment that contains a form
of prospectus shall be deemed to be a new Registration Statement relating to the
securities offered therein, and the offering of such securities at that time
shall be deemed to be the initial BONA FIDE offering thereof.

    The undersigned Registrant hereby undertakes to respond to requests for
information that is incorporated by reference into the prospectus pursuant to
Item 4, 10(b), 11 or 13 of this form, within one business day of receipt of such
request, and to send the incorporated documents by first class mail or other
equally prompt means. This includes information contained in documents filed
subsequent to the effective date of the Registration Statement through the date
of responding to the request.

    The undersigned Registrant hereby undertakes to supply by means of a
post-effective amendment all information concerning a transaction, and the
company being acquired involved therein, that was not the subject of and
included in the Registration Statement when it became effective.
