             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)
 
1.  BASIS OF PRESENTATION
 
     The unaudited financial statements presented herein have been prepared in
accordance with the instructions to Form 10-Q and do not include all of the
information and note disclosures required by generally accepted accounting
principles. These statements should be read in conjunction with the financial
statements and notes thereto included in the Company's Transition Report on Form
10-K for the nine months ended September 30, 1997. The accompanying financial
statements have not been examined by independent accountants in accordance with
generally accepted auditing standards, but in the opinion of management such
financial statements include all adjustments, consisting only of normal
recurring adjustments, necessary to summarize fairly the Company's financial
position and results of operations. Certain prior year amounts have been
reclassified to conform with current year presentation.
 
     On July 2, 1997 a wholly-owned subsidiary of what was formerly called ADT
Limited ("ADT") merged with Tyco International Ltd. ("Former Tyco"). Upon
consummation of the merger, ADT (the surviving corporation) changed its name to
Tyco International Ltd. (the "Company" or "Tyco"). Former Tyco became a
wholly-owned subsidiary of the Company and changed its name to Tyco
International (US) Inc. ("Tyco US"). In addition, subsidiaries of Tyco merged
with INBRAND Corporation ("INBRAND") and Keystone International, Inc.
("Keystone") on August 27, 1997 and August 29, 1997, respectively. These
consolidated financial statements include the consolidated accounts of Tyco, a
company incorporated in Bermuda, and its subsidiaries. They have been prepared
using the pooling of interests method of accounting for the mergers and
therefore reflect the combined financial position, operating results and cash
flows of ADT, Former Tyco and Keystone as if they had been combined for all
periods presented. The restated combined financial statements do not include the
financial position, operating results and cash flows of INBRAND prior to January
1, 1997, due to immateriality.
 
2.  ACQUISITIONS AND DIVESTITURES
 
     During the first quarter of fiscal 1998, the Company purchased businesses
with cash payments of $93.1 million. The cash portion of the acquisitions were
made utilizing cash on hand. Each of these acquisitions was accounted for as a
purchase and, as a result of the acquisitions, approximately $30.7 million in
goodwill was recorded by the Company. Additional purchase liabilities were
recorded totaling $3.0 million for severance, relocation, facilities related and
direct transaction costs.
 
     In addition, during the first quarter, the Company entered into an
agreement to purchase the Sherwood-Davis & Geck division ("Sherwood") of
American Home Products Corporation ("AHP") for cash of $1.77 billion. Sherwood
is a manufacturer of medical and surgical devices, such as catheters, needles
and syringes, sutures, thermometers and other specialized disposable medical
products with annual revenues of approximately $1.0 billion. The Sherwood
acquisition is subject to approval of various regulatory agencies and certain
other conditions. The transaction is expected to close in the second quarter of
fiscal 1998. On February 3, 1998, the Company completed its acquisition of
Holmes Protection Group, Inc. ("Holmes") for $104.0 million in cash. Holmes
provides electronic security systems to commercial and residential customers
throughout the United States and will be integrated with Tyco's Fire and
Security Services Division. The Company intends to account for these
acquisitions as purchases.
 
     In connection with purchase acquisitions consummated during and prior to
the quarter ended December 31, 1997, liabilities for approximately $22.9 million
for severance and related costs and $23.0 million for the shutdown and
consolidation of acquired facilities remained on the balance sheet at December
31, 1997. The Company expects that the termination of employees and
consolidation of facilities related to these acquisitions will be substantially
complete by the end of fiscal 1998.

     In December 1997, Tyco US terminated a $500 million portion of its existing
credit agreement and thereafter had the right to borrow (a) up to $750 million
until June 1998 and (b) up to $500 million until June 2002. Balances outstanding
at the time of termination were repaid through the issuance of private placement
notes, $225 million due in March 1998 and $250 million due in June 1998, all of
which bear interest at LIBOR plus 0.25%. The $475 million of private placement
notes and the $400 million drawn under the portion of the existing credit
agreement due in June 1998 have been classified as long term liabilities, based
on the Company's ability and intent to refinance these obligations on a long
term basis.
 
     On February 13, 1998, Tyco US entered into a new $2.25 billion credit
agreement with a group of commercial banks, giving it the right to borrow (a) up
to $1.75 billion until February 12, 1999, with the ability to extend, at the
option of Tyco US, to February 12, 2000, and (b) up to $0.5 billion until
February 12, 2003, such term converting from a 364-day term to a five year term
upon termination of the existing credit agreement. Interest payable on
borrowings is variable based upon the borrower's option of selecting a
Eurodollar rate plus margins ranging from 0.17% to 0.19%, a certificate of
deposit rate plus margins ranging from 0.295% to 0.315%, or a base rate, as
defined. If the outstanding principal amount of loans equals or exceeds
one-third of the commitments, the Eurodollar and certificate of deposit margins
are increased by 0.10%. Repayment of amounts outstanding under this agreement is
guaranteed by the Company.
 
     Simultaneous with the closing of the new credit agreement, Tyco US reduced
aggregate commitments available under its existing credit agreement to $950
million by reducing the $750 million portion to $450 million due in June 1998
and amended the terms and conditions, including interest rates, of the existing
credit agreement to conform to the new credit agreement.
 
     Uncommitted lines of credit are borrowings by Tyco US from commercial banks
on an "as offered" basis. Borrowings and repayments occur daily and contain no
significant terms other than due dates and interest rates. The due dates
generally range from overnight to 90 days and interest rates approximate those
available under the Tyco US credit agreement.

     NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED) -- (CONTINUED)
 
     Under its various loan agreements, the Company is required to meet certain
covenants, none of which is considered restrictive to the operations of the
Company.
 
     During the quarters ended December 31, 1997 and 1996, respectively, 124,264
and 100 of the Liquid Yield Option Notes ("LYONs") with a carrying value of
$55.1 and $0.3 million were exchanged for 3,376,990 and 2,717 common shares of
the Company. Extraordinary items in the quarter ended December 31, 1997 include
the write-off of net unamortized deferred refinance costs and other related fees
of $0.9, which were recorded upon the early extinguishment of the related LYONs.
The extraordinary items in 1996 includes $2.6 million for the write-off of
deferred financing costs upon the early extinguishment of debt agreements by
ADT.
 
4.  EARNINGS PER SHARE
 
     During the first quarter of fiscal 1998, the Company was required to adopt
Statement of Financial Accounting Standards ("SFAS") No. 128, "Earnings per
Share." SFAS No. 128 specifies the computation, presentation and disclosure
requirements for earnings per share and is substantially similar to the
standards recently issued by the International Accounting Standards Committee
entitled "International Accounting Standards Earnings Per Share". Prior period
earnings per share data has been restated in accordance with the provisions of
this statement.
 
     The reconciliations between basic and diluted earnings per share are as

exchange of LYONs and from the assumed conversion of convertible redeemable
preference shares, which were redeemed during fiscal 1997, are anti-dilutive in
the quarter ended December 31, 1996. Income before extraordinary items in the
quarter ended December 31, 1996 was adjusted for the dividends on preference
shares in the calculation of earnings per share.

9.     COMMITMENTS AND CONTINGENCIES
 
     In the normal course of business, the Company is liable for contract
completion and product performance. In addition, the Company is in receipt of
notifications from various environmental agencies that conditions at a number of
sites where hazardous wastes were disposed of by the Company and other persons
may require cleanup and other possible remedial action. In the opinion of
management, these obligations will not materially affect the Company's financial
position or results of operations.

ITEM 2 -- MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
OPERATING RESULTS
 
     On July 2, 1997, a wholly-owned subsidiary of what was formerly called ADT
Limited ("ADT") merged with Tyco International Ltd. ("Former Tyco"). Upon
consummation of the merger, ADT (the surviving corporation) changed its name to
Tyco International Ltd. (the "Company" or "Tyco"). In August 1997, the Company
acquired Keystone International, Inc. and INBRAND Corporation. All three of
these transactions were accounted for as a pooling of interests and,
accordingly, the consolidated financial statements reflect the combined
financial position and results of operations and cash flows of ADT, Former Tyco,
Keystone and INBRAND for all periods presented except that the consolidated
financial statements for periods prior to January 1, 1997 do not include INBRAND
due to immateriality. See Note 1 to the consolidated financial statements
presented herein. These transactions are more fully discussed in the Company's
Consolidated Financial Statements and notes thereto as of September 30, 1997
previously filed on Form 10-K.
 
RESULTS OF OPERATIONS.
 
     Information for all periods presented below reflects the grouping of the
Company's businesses into four business segments consisting of Disposable and
Specialty Products, Fire and Security Services, Flow Control Products, and
Electrical and Electronic Components.
 
     In September 1997, the Company changed its fiscal year end from December 31
to September 30. In the discussions below, the results of operations for fiscal
1998 compare the first quarter ended December 31, 1997 with the corresponding
quarter ended December 31, 1996.
 
  Overview
 
     Net income before extraordinary item was $240.8 million, or $0.43 per share
on a diluted basis for the quarter ended December 31, 1997 as compared to $68.1
million, or $0.14 per share, for the quarter ended December 31, 1996. Excluding
the $80.3 million ($0.16 per share) after-tax net charge for restructuring and
other non-recurring items recorded in the quarter ended December 31, 1996,
income before extraordinary item rose 62.3% from $148.4 million, or $0.30 per
share. The increase was attributable to increased income from operations
primarily in the Electrical and Electronic Components and Fire and Security
Services segments and, to a lesser extent, the Disposable and Specialty Products
and Flow Control Products segments.
 
  Quarter ended December 31, 1997 Compared to Quarter ended December 31, 1996:
 
     Sales increased 20.4% during the quarter ended December 31, 1997 to $2.69
billion from $2.23 billion in the quarter ended December 31, 1996.
 
     Sales of the Electrical and Electronic Components group increased $213.7
million to $334.3 million, or 177.2%, principally due to increased sales of
$189.3 million at Tyco Submarine Systems Limited (TSSL), as well as increased
sales at Tyco Printed Circuit Group (TPCG), offset slightly by decreased sales
at Allied Electrical Conduit. The increased sales at TSSL resulted principally
from the acquisition of AT&T's submarine systems business in July 1997.
 
     Sales of the Fire and Security Services Group increased $107.6 million to
$1.13 billion, or 10.6%, principally due to increased sales of $75.5 million in
the North America, Australia and Europe geographic regions for the Company's
fire protection operations, and increased worldwide sales of $46.8 million in
the Company's electronic security services business. Net sales increased in the
fire protection and security businesses primarily due to an increase in the
volume of the service business.
 
     Sales of the Disposable and Specialty Products Group increased $95.6
million to $676.6 million, or 16.4%, principally due to increased sales of $65.5
million at Kendall, $20.4 million at Tyco Plastics and $10.7 million at ADT
Automotive. At Kendall the increase in sales resulted principally from the
inclusion of INBRAND in 1997, as well as internal growth at the Ludlow Technical
Products division.
 
     Sales of the Flow Control Products Group increased $38.5 million to $550.0
million, or 7.5%, primarily reflecting increased volume at existing businesses
at Allied Tube & Conduit, including businesses acquired during the first quarter
of fiscal 1997.
 
                                       10

     Pre-tax income before extraordinary item was $359.4 million for the quarter
ended December 31, 1997, as compared to $98.6 million for the quarter ended
December 31, 1996. Pretax income for the quarter ended December 31, 1996
includes net charges of $115.1 million for non-recurring items in ADT's
electronic security services operations. Excluding these non-recurring charges,
pre-tax income increased $145.7 million, or 68.2%, from $213.7 million.
Amortization expense for goodwill and other intangible assets was $26.9 million
for the quarter ended December 31, 1997 and $23.5 million for the quarter ended
December 31, 1996. The following analysis is exclusive of the non-recurring
amounts to present the comparability of recurring operations.
 
     For the quarter ended December 31, 1997 as compared to the quarter ended
December 31, 1996, operating profits of the Electrical and Electronic Components
group increased $49.1 million to $71.6 million, or 218.2%. Operating profits
were 21.4% of sales in the quarter ended December 31, 1997 and 18.7% in the
quarter ended December 31, 1996. The increase was principally due to the
acquisition of AT&T's submarine systems business in July 1997, as well as
increased sales and better margins at TPCG, offset slightly by decreased sales
at Allied Electrical Conduit.
 
     Fire and Security Services profits increased $45.7 million to $146.4
million, or 45.4%. Operating profits were 13.0% of sales in the quarter ended
December 31, 1997 and 9.9% in the quarter ended December 31, 1996. The increase
was principally due to increases in the service volume of the fire protection
and security businesses mentioned above, higher volume and improved margins in
the Company's fire protection contracting businesses in North America, Australia
and New Zealand, as well as, improved volume and margins in the security service
businesses in North America and the United Kingdom.
 
     Operating profits for the Disposable and Specialty Products Group increased
$27.2 million to $123.6 million, or 28.2%. Operating profits were 18.3% of sales
in the quarter ended December 31, 1997 and 16.6% in the quarter ended December
31, 1996. The increase was principally due to higher sales and increased margins
in Kendall's North American healthcare business, including INBRAND, higher sales
and margins at Tyco Plastics and higher profit at ADT Automotive, where the
volume of automobiles placed in auctions increased.
 
     Operating profits for the Flow Control Group increased $20.0 million to
$71.9 million, or 38.5%. Operating profits were 13.1% of sales in the quarter
ended December 31, 1997 and 10.1% in the quarter ended December 31, 1996. The
increase was principally due increased margins in the Company's North American
and European flow control products operations, including Keystone's valve
products, which have been integrated into the operations of Grinnell and Europe
Flow Control.
 
     The effect of average foreign exchange rates during the quarter ended
December 31, 1997 as compared to the quarter ended December 31, 1996 was not
material to the Company's total sales or operating profits.
 
     The effective income tax rate was 33% during the quarter ended December 31,
1997 and 31% during the quarter ended December 31, 1996.
 
LIQUIDITY AND CAPITAL RESOURCES
 
     As presented in the Consolidated Statement of Cash Flows, net cash provided
by operating activities was $142.6 million during the first quarter of fiscal
1998. Accounts payable and accrued expenses decreased $237.1 million which
resulted principally from spending for merger, restructuring and other
non-recurring costs during the quarter. Net changes in other working capital
accounts were not significant during the period. The impact of changes in
foreign exchange rates did not materially affect net working capital during the
quarter.
 
     During the first quarter of fiscal 1998, the Company used cash to (i)
acquire companies for an aggregate of $93.1 million in cash, (ii) purchase
$148.5 million of property, plant and equipment; and (iii) pay dividends of
$13.2 million and received $149.5 million upon the exercise of common share
options.
 
     At December 31, 1997 the Company's total debt was $2.64 billion, a slight
decrease as compared to $2.73 billion at September 30, 1997. The decrease
resulted principally from the exchange of LYON's debt with a $55.1 million
principal balance for common shares and the net repayment of various borrowings.
Shareholders' equity was $3.84 billion, or $6.99 per share, at December 31,
1997, compared to $3.43 billion, or
 
                                       11

<PAGE>   14
 
$6.39 per share, at September 30, 1997. Goodwill and other intangible assets was
$2.95 billion at December 31, 1997 compared to $2.93 billion at September 30,
1997. The increase in shareholders' equity was due primarily to net income of
$239.9 million and proceeds from the exercise of options. Total debt as a
percent of total capitalization (total debt and shareholders' equity) was 41% at
December 31, 1997 and 44% at September 30, 1997.
 
     In December 1997, Tyco US terminated a $500 million portion of its existing
credit agreement and thereafter had the right to borrow (a) up to $750 million
until June 1998 and (b) up to $500 million until June 2002. Balances outstanding
at the time of termination were repaid through the issuance of private placement
notes, $225 million due in March 1998 and $250 million due in June 1998, all of
which bear interest at LIBOR plus 0.25%. The $475 million of private placement
notes and the $400 million drawn under the portion of the existing credit
agreement due in June 1998 have been classified as long term liabilities, based
on the Company's ability and intent to refinance these obligations on a long
term basis.
 
     On February 13, 1998, Tyco US entered into a new $2.25 billion credit
agreement with a group of commercial banks, giving it the right to borrow (a) up
to $1.75 billion until February 12, 1999, with the ability to extend, at the
option of Tyco US, to February 12, 2000, and (b) up to $0.5 billion until
February 12, 2003, such term converting from a 364-day term to a five year term
upon termination of the existing credit agreement. Repayment of amounts
outstanding under this agreement is guaranteed by the Company.
 
     Simultaneous with the closing of the new credit agreement, Tyco US reduced
aggregate commitments available under its existing credit agreement to $950
million by reducing the $750 million portion to $450 million due in June 1998
and amended the terms and conditions, including interest rates, of the existing
credit agreement to conform to the new credit agreement.
 
     Working capital requirements for the remainder of fiscal 1998 are not
expected to significantly increase as compared to fiscal 1997. The level of
capital expenditures is not expected to increase materially in fiscal 1998 as
compared to annualized fiscal 1997. The Company believes that its funding
sources are adequate for its anticipated requirements, including the acquisition
of Sherwood for approximately $1.77 billion in the second quarter of fiscal
1998, through expected cash flow from operations, established financial
arrangements and accessing equity and debt capital markets. In December 1997 the
Company filed a shelf registration statement for the issuance of debt and equity
up to $2.0 billion.
 
BACKLOG
 
     The backlog of unfilled orders was approximately $2.7 billion at December
31, 1997 as compared to $2.3 billion at September 30, 1997. Backlog increased in
the Company's Electrical and Electronic Components, Fire and Security Services
and Flow Control Group segments. Within Electrical and Electronic Components,
backlog increased principally due to the acquired backlog of AT&T's submarine
systems business, as well as new projects issued to TSSL. Within Fire and
Security Services, backlog increased principally due to an increase in backlog
at the Company's U.S. security business and the Europe fire business.

the Borrower wishes to eliminate the effect of any change in generally accepted
accounting principles on the operation of any covenant contained in Article 5 or

to their Commitments, while a "Money Market Borrowing" is a Borrowing under
Section 2.03 in which the Bank participants are determined on the basis of their
bids in accordance therewith) or by reference to the maturity of Loans
comprising such Borrowing (e.g., a "TERM BORROWING" is a Borrowing comprised of
Term Loans).

                                   THE CREDITS

         SECTION 2.01. Commitments to Lend. (a) Revolving Credit Loans. Each
Bank severally agrees, on the terms and conditions set forth in this Agreement,
to make loans to the Borrower pursuant to this Section 2.01 from time to time
prior to the Termination Date in amounts such that the aggregate principal
amount of Committed Loans by such Bank at any one time outstanding shall not
exceed the amount of its Commitment. Each Borrowing under this Section shall be
in an aggregate principal amount of $10,000,000 or any larger multiple of
$1,000,000 (except that any such Borrowing may be in the aggregate amount
available in accordance with Section 3.03(b)) and shall be made from the several
Banks ratably in proportion to their respective Commitments. Within the
foregoing limits, the Borrower may borrow under this Section, repay or, to the
extent permitted by Section 2.11, prepay Loans and reborrow at any time prior to
the Termination Date under this Section 2.01.

         (b) Term Loans. Each Bank severally agrees, on the terms and conditions
set forth in this Agreement, to make a loan to the Borrower on the Termination
Date in an aggregate amount up to but not exceeding the amount of its
Commitment.

         SECTION 2.02. Notice of Committed Borrowing. The Borrower shall give
the Agent notice (a "Notice of Committed Borrowing") not later than 11:00 A.M.
(New York City time) on (x) the date of each Base Rate Borrowing, (y) the second
Domestic Business Day before each CD Borrowing and (z) the third Euro-Dollar
Business Day before each Euro-Dollar Borrowing, specifying:

         (a) the date of such Borrowing, which shall be a Domestic Business Day
in the case of a Domestic Borrowing or a Euro-Dollar Business Day in the case of
a Euro-Dollar Borrowing,

         (b) the aggregate amount of such Borrowing,

         (c) whether the Loans comprising such Borrowing are to bear interest
initially at the Base Rate, a CD Rate or a Euro-Dollar Rate, and

         (d) in the case of a Fixed Rate Borrowing, the duration of the initial
Interest Period applicable thereto, subject to the provisions of the definition
of Interest Period.

          SECTION 2.03.  The Money Market Borrowings.

         (a) The Money Market Option. In addition to Committed Borrowings
pursuant to Section 2.01, the Borrower may, as set forth in this Section,
request the Banks, at any time prior to the Termination Date, to make offers to
make Money Market Loans to the Borrower. The Banks may, but shall have no
obligation to, make such offers and the Borrower may, but shall have no
obligation to, accept any such offers in the manner set forth in this Section.


                                       17
<PAGE>   23
         (b) Money Market Quote Request. When the Borrower wishes to request
offers to make Money Market Loans under this Section, it shall transmit to the
Agent by telex or facsimile transmission a Money Market Quote Request
substantially in the form of Exhibit B hereto so as to be received no later than
10:30 A.M. (New York City time) on (x) the fifth Euro-Dollar Business Day prior
to the date of Borrowing proposed therein, in the case of a LIBOR Auction or (y)
the Domestic Business Day next preceding the date of Borrowing proposed therein,
in the case of an Absolute Rate Auction (or, in either case, such other time or
date as the Borrower and the Agent shall have mutually agreed and shall have
notified to the Banks not later than the date of the Money Market Quote Request
for the first LIBOR Auction or Absolute Rate Auction for which such change is to
be effective), specifying:

              (i)   the proposed date of Borrowing, which shall be a Euro-Dollar
          Business Day in the case of a LIBOR Auction or a Domestic Business Day
          in the case of an Absolute Rate Auction,

              (ii)  the aggregate amount of such Borrowing, which shall be
          $10,000,000 or a larger multiple of $1,000,000,

              (iii) the duration of the Interest Period applicable thereto,
          subject to the provisions of the definition of Interest Period, and

              (iv)  whether the Money Market Quotes requested are to set forth a
          Money Market Margin or a Money Market Absolute Rate.

The Borrower may request offers to make Money Market Loans for more than one
Interest Period in a single Money Market Quote Request. No Money Market Quote
Request shall be given within five Euro-Dollar Business Days (or such other
number of days as the Borrower and the Agent may agree) of any other Money
Market Quote Request.

         (c) Invitation for Money Market Quotes. Promptly upon receipt of a
Money Market Quote Request, the Agent shall send to the Banks by telex or
facsimile transmission an Invitation for Money Market Quotes substantially in
the form of Exhibit C hereto, which shall constitute an invitation by the
Borrower to each Bank to submit Money Market Quotes offering to make the Money
Market Loans to which such Money Market Quote Request relates in accordance with
this Section.

         (d) Submission and Contents of Money Market Quotes. (i) Each Bank may,
in its sole discretion, submit a Money Market Quote containing an offer or
offers to make Money Market Loans in response to any Invitation for Money Market
Quotes. Each Money Market Quote must comply with the requirements of this
subsection 2.03(d) and must be submitted to the Agent by telex or facsimile
transmission at its offices specified in or pursuant to Section 9.01 not later
than (x) 2:00 P.M. (New York City time) on the fourth Euro-Dollar Business Day
prior to the proposed date of Borrowing, in the case of a LIBOR Auction or (y)
9:30 A.M. (New York City time) on the proposed date of Borrowing, in the case of
an Absolute Rate Auction (or, in either


                                       18
<PAGE>   24
case, such other time or date as the Borrower and the Agent shall have mutually
agreed and shall have notified to the Banks not later than the date of the Money
Market Quote Request for the first LIBOR Auction or Absolute Rate Auction for
which such change is to be effective); provided that Money Market Quotes
submitted by the Agent (or any affiliate of the Agent) in the capacity of a Bank
may be submitted, and may only be submitted, if the Agent or such affiliate
notifies the Borrower of the terms of the offer or offers contained therein not
later than (x) one hour prior to the deadline for the other Banks, in the case
of a LIBOR Auction or (y) 15 minutes prior to the deadline for the other Banks,
in the case of an Absolute Rate Auction. Subject to Articles 3 and 6, any Money
Market Quote so made shall be irrevocable except with the written consent of the
Agent given on the instructions of the Borrower.

              (ii) Each Money Market Quote shall be in substantially the form of
          Exhibit D hereto and shall in any case specify:

                   (A) the proposed date of Borrowing and the Interest Period
              therefor,

                   (B) the principal amount of the Money Market Loan for which
              each such offer is being made, which principal amount (w) may be
              greater than or less than the Commitment of the quoting Bank, (x)
              must be $5,000,000 or a larger multiple of $1,000,000, (y) may not
              exceed the principal amount of Money Market Loans for which offers
              were requested and (z) may be subject to an aggregate limitation
              as to the principal amount of Money Market Loans for which offers
              being made by such quoting Bank may be accepted,

                   (C) in the case of a LIBOR Auction, the margin above or below
              the applicable London Interbank Offered Rate (the "Money Market
              Margin") offered for each such Money Market Loan, expressed as a
              percentage (specified to the nearest 1/10,000th of 1%) to be added
              to or subtracted from the applicable London Interbank Offered
              Rate,

                   (D) in the case of an Absolute Rate Auction, the rate of
              interest per annum (specified to the nearest 1/10,000th of 1%)
              (the "Money Market Absolute Rate") offered for each such Money
              Market Loan, and

                   (E) the identity of the quoting Bank.

A Money Market Quote may set forth up to five separate offers by the quoting
Bank with respect to each Interest Period specified in the related Invitation
for Money Market Quotes.

        (iii) Any Money Market Quote shall be disregarded if it:

                   (A) is not substantially in conformity with Exhibit D hereto
              or does not specify all of the information required by subsection
              2.03(d)(ii);


                                       19
<PAGE>   25
                   (B) contains qualifying, conditional or similar language;

                   (C) proposes terms other than or in addition to those set
              forth in the applicable Invitation for Money Market Quotes; or

                   (D) arrives after the time set forth in subsection
              2.03(d)(i).

          (e) Notice to Borrower. The Agent shall promptly notify the Borrower
of the terms (x) of any Money Market Quote submitted by a Bank that is in
accordance with subsection 2.03(d) and (y) of any Money Market Quote that
amends, modifies or is otherwise inconsistent with a previous Money Market Quote
submitted by such Bank with respect to the same Money Market Quote Request. Any
such subsequent Money Market Quote shall be disregarded by the Agent unless such
subsequent Money Market Quote is submitted solely to correct a manifest error in
such former Money Market Quote. The Agent's notice to the Borrower shall specify
(A) the aggregate principal amount of Money Market Loans for which offers have
been received for each Interest Period specified in the related Money Market
Quote Request, (B) the respective principal amounts and Money Market Margins or
Money Market Absolute Rates, as the case may be, so offered and (C) if
applicable, limitations on the aggregate principal amount of Money Market Loans
for which offers in any single Money Market Quote may be accepted.

          (f) Acceptance and Notice by Borrower. Not later than 10:30 A.M. (New
York City time) on (x) the third Euro-Dollar Business Day prior to the proposed
date of Borrowing, in the case of a LIBOR Auction or (y) the proposed date of
Borrowing, in the case of an Absolute Rate Auction (or, in either case, such
other time or date as the Borrower and the Agent shall have mutually agreed and
shall have notified to the Banks not later than the date of the Money Market
Quote Request for the first LIBOR Auction or Absolute Rate Auction for which
such change is to be effective), the Borrower shall notify the Agent of its
acceptance or non-acceptance of the offers so notified to it pursuant to
subsection 2.03(e) (and the failure of the Borrower to give such notice by such
time shall constitute non-acceptance) and the Agent shall promptly notify each
affected Bank. In the case of acceptance, such notice (a "Notice of Money Market
Borrowing") shall specify the aggregate principal amount of offers for each
Interest Period that are accepted. The Borrower may, but shall not be obligated
to, accept any Money Market Quote in whole or in part; provided that:

                  (i)   the aggregate principal amount of each Money Market
         Borrowing may not exceed the applicable amount set forth in the related
         Money Market Quote Request,

                  (ii)  the principal amount of each Money Market Borrowing must
         be $10,000,000 or a larger multiple of $1,000,000,

                  (iii) acceptance of offers may only be made on the basis of
         ascending order of Money Market Margins or Money Market Absolute Rates,
         as the case may be, in each case beginning with the lowest rate so
         offered, and


                                       20
<PAGE>   26
                  (iv) the Borrower may not accept any offer where the Agent has
         advised the Borrower that such offer is described in subsection
         2.03(d)(iii) or that otherwise fails to comply with the requirements of
         this Agreement.

         (g) Allocation by Agent. If offers are made by two or more Banks with
the same Money Market Margins or Money Market Absolute Rates, as the case may
be, for a greater aggregate principal amount than the amount in respect of which
such offers are accepted for the related Interest Period, the principal amount
of Money Market Loans in respect of which such offers are accepted shall be
allocated by the Agent among such Banks as nearly as possible (in multiples of
$1,000,000, as the Agent may deem appropriate) in proportion to the aggregate
principal amounts of such offers. Determinations by the Agent of the amounts of
Money Market Loans shall be conclusive in the absence of manifest error.

         SECTION 2.04.  Notice to Banks; Funding of Loans.

         (a) Upon receipt of a Notice of Borrowing, the Agent shall promptly
notify each Bank of the contents thereof and of such Bank's share (if any) of
such Borrowing and such Notice of Borrowing shall not thereafter be revocable by
the Borrower.

         (b) Not later than 2:00 P.M. (New York City time) on the date of each
Borrowing, each Bank participating therein shall make available its share of
such Borrowing, in Federal or other funds immediately available in New York
City, to the Agent at its address referred to in Section 9.01. Unless the Agent
determines that any applicable condition specified in Article 3 has not been
satisfied or waived in accordance with Section 9.05, the Agent will make the
funds so received from the Banks available to the Borrower no later than 3:00
P.M. (New York City time) on such date, in Federal or other funds immediately
available in New York City, as directed by the Borrower.

         (c) If any Bank makes a new Loan hereunder on any day on which the
Borrower is to repay all or any part of an outstanding Loan from such Bank, such
Bank shall apply the proceeds of its new Loan to make such repayment and only an
amount equal to the difference (if any) between the amount being borrowed and
the amount being repaid shall be made available by such Bank to the Agent as
provided in subsection 2.04(b), 2.04(c), or remitted by the Borrower to the
Agent as provided in Section 2.12, as the case may be.

         (d) If any Bank makes a Term Loan to the Borrower hereunder on a day on
which the Borrower is to repay all or any part of an outstanding Revolving
Credit Loan from such Bank, such Bank shall apply the proceeds of its Term Loan
to make such repayment and only an amount equal to the difference (if any)
between the amount being borrowed and the amount being repaid shall be made
available by such Bank to the Agent as provided in subsection 2.04(b), 2.04(c),
or remitted by the Borrower to the Agent as provided in Section 2.12, as the
case may be.


                                       21
<PAGE>   27
          (e) Unless the Agent shall have received notice from a Bank prior to
the date of any Borrowing that such Bank will not make available to the Agent
such Bank's share of such Borrowing, the Agent may assume that such Bank has
made such share available to the Agent on the date of such Borrowing in
accordance with subsection (b) and (c) of this Section 2.04 and the Agent may,
in reliance upon such assumption, make available to the Borrower on such date a
corresponding amount. If and to the extent that such Bank shall not have so made
such share available to the Agent, such Bank and, if such Bank shall not have
paid such amount to the Agent within two Domestic Business Days of the Agent's
demand therefor, the Borrower severally agree to repay to the Agent forthwith on
demand such corresponding amount together with interest thereon, for each day
from the date such amount is made available to the Borrower until the date such
amount is repaid to the Agent, at the Federal Funds Rate. If such Bank shall
repay to the Agent such corresponding amount, such amount so repaid shall
constitute such Bank's Loan included in such Borrowing for purposes of this
Agreement.

          (f) The failure of any Bank to make any Loan to be made by it on the
date specified therefor shall not relieve any other Bank of any obligation to
make a Loan on such date.

          SECTION 2.05. Promissory Notes. (a) The Loans of each Bank shall be
evidenced by a single Promissory Note payable to the order of such Bank for the
account of its Applicable Lending Office in an amount equal to the aggregate
unpaid principal amount of such Bank's Loans.

          (b) Each Bank may, by notice to the Borrower and the Agent, request
that its Loans of a particular type be evidenced by a separate Promissory Note
in an amount equal to the aggregate unpaid principal amount of such Loans. Each
such Promissory Note shall be in substantially the form of Exhibit A hereto with
appropriate modifications to reflect the fact that it evidences solely Loans of
the relevant type. Each reference in this Agreement to the "Promissory Note" of
such Bank shall be deemed to refer to and include any or all of such Promissory
Notes, as the context may require.

          (c) Upon receipt of each Bank's Promissory Note pursuant to Section
3.01(b), the Agent shall forward such Promissory Note to such Bank. Each Bank
shall record the date, amount, type and maturity of each Loan made by it and the
date and amount of each payment of principal made by the Borrower with respect
thereto, and may, if such Bank so elects in connection with any transfer or
enforcement of its Promissory Note, endorse on the schedule forming a part
thereof appropriate notations to evidence the foregoing information with respect
to each such Loan then outstanding; provided that the failure of any Bank to
make any such recordation or endorsement shall not affect the obligations of the
Borrower hereunder or under the Promissory Notes. Each Bank is hereby
irrevocably authorized by the Borrower so to endorse its Promissory Note and to
attach to and make a part of its Promissory Note a continuation of any such
schedule as and when required.


                                       22
<PAGE>   28
          SECTION 2.06.  Maturity of Loans.  (a) Each Revolving Credit Loan 
shall mature, and the principal amount thereof shall be due and payable
(together with interest accrued thereon), on the Termination Date.

          (b) Each Term Loan shall mature, and the principal amount thereof
shall be due and payable, together with accrued interest thereon, on the Final
Maturity Date.

          (c) Each Money Market Loan included in any Money Market Borrowing
shall mature, and the principal amount thereof shall be due and payable
(together with interest accrued thereon), on the last day of the Interest Period
applicable to such Borrowing.

         SECTION 2.07. Interest Rates. (a) Each Base Rate Loan shall bear
interest on the outstanding principal amount thereof, for each day from the date
such Loan is made until it becomes due, at a rate per annum equal to the Base
Rate for each such day. Such interest shall be payable at maturity, quarterly in
arrears on each Quarterly Payment Date prior to maturity and, with respect to
the principal amount of any Base Rate Loan converted to a CD Loan or a
Euro-Dollar Loan, on the date such amount is so converted. Any overdue principal
of or interest on any Base Rate Loan shall bear interest, payable on demand, for
each day from and including the date payment thereof was due to but excluding
the date of actual payment, at a rate per annum equal to the sum of 2% plus the
rate otherwise applicable to Base Rate Loans for each such day.

          (b) Each CD Loan shall bear interest on the outstanding principal
amount thereof, for each day during each Interest Period applicable thereto, at
a rate per annum equal to the sum of the Applicable Margin for each such day
plus the applicable Adjusted CD Rate for such Interest Period; provided that if
any CD Loan shall, as a result of the further proviso to the definition of
Interest Period, have an Interest Period of less than 30 days, such CD Loan
shall bear interest during such Interest Period at the rate applicable to Base
Rate Loans during such period. Such interest shall be payable for each Interest
Period on the last day thereof and, if such Interest Period is longer than 90
days, at intervals of 90 days after the first day thereof. Any overdue principal
of or interest on any CD Loan shall bear interest, payable on demand, for each
day from and including the date payment thereof was due to but excluding the
date of actual payment, at a rate per annum equal to the sum of 2% plus the
higher of (i) the sum of the Applicable Margin for each such day plus the
Adjusted CD Rate applicable to such Loan on the day before such payment was due
and (ii) the rate applicable to Base Rate Loans for each such day.

         The "Adjusted CD Rate" applicable to any Interest Period means a rate
per annum determined pursuant to the following formula:

                                    [ CDBR        ]*
                  ACDR     =        [ ----------  ] + AR
                                    [ 1.00 - DRP  ]

                  ACDR     =        Adjusted CD Rate
                  CDBR     =        CD Base Rate


                                       23
<PAGE>   29
                  DRP      =       Domestic Reserve Percentage
                  AR       =       Assessment Rate
- ----------
* The amount in brackets being rounded upward, if necessary, to the next higher
1/100 of 1%

         The "CD BASE RATE" applicable to any Interest Period is the rate of
interest determined by the Agent to be the average (rounded upward, if
necessary, to the next higher 1/100 of 1%) of the prevailing rates per annum bid
at 10:00 A.M. (New York City time) (or as soon thereafter as practicable) on the
first day of such Interest Period by two or more New York certificate of deposit
dealers of recognized standing for the purchase at face value from each CD
Reference Bank of its certificates of deposit in an amount comparable to the
principal amount of the CD Loan of such CD Reference Bank to which such Interest
Period applies and having a maturity comparable to such Interest Period.

         "DOMESTIC RESERVE PERCENTAGE" means for any day that percentage
(expressed as a decimal) which is in effect on such day, as prescribed by the
Board of Governors of the Federal Reserve System (or any successor) for
determining the maximum reserve requirement (including without limitation any
basic, supplemental or emergency reserves) for a member bank of the Federal
Reserve System in New York City with deposits exceeding five billion dollars in
respect of new non-personal time deposits in dollars in New York City having a
maturity comparable to the related Interest Period and in an amount of $100,000
or more. The Adjusted CD Rate shall be adjusted automatically on and as of the
effective date of any change in the Domestic Reserve Percentage.

         "ASSESSMENT RATE" means for any day the annual assessment rate in
effect on such day which is payable by a member of the Bank Insurance Fund
classified as adequately capitalized and within supervisory subgroup "A" (or a

C.F.R. Section 327.4(a) or any successor provision (a "BIF Member") to the
Federal Deposit Insurance Corporation (or any successor) for the Federal Deposit
Insurance Corporation's (or such successor's) insuring time deposits at offices

         (c) Each Euro-Dollar Loan shall bear interest on the outstanding
principal amount thereof, for each day during each Interest Period applicable
thereto, at a rate per annum equal to the sum of the Applicable Margin for each
such day plus the applicable London Interbank Offered Rate for such Interest
Period. Such interest shall be payable for each Interest Period on the last day
thereof and, if such Interest Period is longer than three months, at intervals
of three months after the first day thereof.

         The "LONDON INTERBANK OFFERED RATE" applicable to any Interest Period
means the average (rounded upward, if necessary, to the next higher 1/16 of 1%)
of the respective rates per annum at which deposits in dollars are offered to
each of the Euro-Dollar Reference Banks in the

<PAGE>   30
London interbank market at approximately 11:00 A.M. (London time) two
Euro-Dollar Business Days before the first day of such Interest Period in an
amount approximately equal to the principal amount of the Euro-Dollar Loan of
such Euro-Dollar Reference Bank to which such Interest Period is to apply and
for a period of time comparable to such Interest Period.

          (d) Any overdue principal of or interest on any Euro-Dollar Loan shall
bear interest, payable on demand, for each day from and including the date
payment thereof was due to but excluding the date of actual payment, at a rate
per annum equal to the sum of 2% plus the higher of (i) the sum of the
Applicable Margin for such day plus the London Interbank Offered Rate applicable
to such Loan on the day before such payment was due and (ii) the Applicable
Margin for such day plus the quotient obtained (rounded upward, if necessary, to
the next higher 1/100 of 1%) by dividing (x) the average (rounded upward, if
necessary, to the next higher 1/16 of 1%) of the respective rates per annum at
which one day (or, if such amount due remains unpaid more than three Euro-Dollar
Business Days, then for such other period of time not longer than six months as
the Agent may select) deposits in dollars in an amount approximately equal to
such overdue payment due to each of the Euro-Dollar Reference Banks are offered
to such Euro-Dollar Reference Bank in the London interbank market for the
applicable period determined as provided above by (y) 1.00 minus the Euro-Dollar
Reserve Percentage (or, if the circumstances described in subsection (a) or (b)
of Section 8.01 shall exist, at a rate per annum equal to the sum of 2% plus the
rate applicable to Base Rate Loans for such day).

          (e) Subject to Section 8.01(a), each Money Market LIBOR Loan shall
bear interest on the outstanding principal amount thereof, for each day during
the Interest Period applicable thereto, at a rate per annum equal to the sum of
the London Interbank Offered Rate for such Interest Period (determined in
accordance with Section 2.07(c) as if the related Money Market LIBOR Borrowing
were a Committed Euro-Dollar Borrowing) plus (or minus) the Money Market Margin
quoted by the Bank making such Loan in accordance with Section 2.03. Each Money
Market Absolute Rate Loan shall bear interest on the outstanding principal
amount thereof, for each day during the Interest Period applicable thereto, at a
rate per annum equal to the Money Market Absolute Rate quoted by the Bank making
such Loan in accordance with Section 2.03. Such interest shall be payable for
each Interest Period on the last day thereof and, if such Interest Period is
longer than three months, at intervals of three months after the first day
thereof. Any overdue principal of or interest on any Money Market Loan shall
bear interest, payable on demand, for each day from and including the date
payment thereof was due to but excluding the date of actual payment, at a rate
per annum equal to the sum of 2% plus the Base Rate for each such day.

          (f) The Agent shall determine each interest rate applicable to the
Loans hereunder. The Agent shall give prompt notice to the Borrower and the
participating Banks of each rate of interest so determined, and its
determination thereof shall be conclusive in the absence of manifest error.

          (g) Each Reference Bank agrees to use its best efforts to furnish
quotations to the Agent as contemplated by this Section. If any Reference Bank
does not furnish a timely quotation, the


                                       25
<PAGE>   31
Agent shall determine the relevant interest rate on the basis of the quotation
or quotations furnished by the remaining Reference Bank or Banks or, if none of
such quotations is available on a timely basis, the provisions of Section 8.01
shall apply.

          (b) Accrued fees under this Section shall be payable quarterly in
arrears on each Quarterly Payment Date and upon the date of termination of the
Commitments in their entirety (and, if later, the date the Loans shall be repaid
in their entirety).

         SECTION 2.09. Optional Termination or Reduction of Commitments. The
Borrower may, upon at least three Domestic Business Days' notice to the Agent,
(i) terminate the Commitments at any time, if no Loans are outstanding at such
time or (ii) ratably reduce from time to time by an aggregate amount of
$10,000,000 or any larger multiple thereof, the aggregate amount of the
Commitments in excess of the aggregate outstanding principal amount of the
Loans. Promptly after receiving a notice pursuant to this Section, the Agent
shall notify each Bank of the contents thereof.

         SECTION 2.10. Mandatory Termination of Commitments. The Commitments
shall terminate on the Termination Date, and any Revolving Credit Loans then
outstanding (together with accrued interest thereon) shall be due and payable on
such date.

         SECTION 2.11. Optional Prepayments. (a) The Borrower may (i) upon at
least one Domestic Business Day's notice to the Agent, prepay any Group of Base
Rate Loans (or any Money Market Borrowing bearing interest at the Base Rate
pursuant to Section 8.01(a)), (ii) upon at least three Domestic Business Days'
notice to the Agent, subject to Section 2.13, prepay any Group of CD Loans and
(iii) upon at least three Euro-Dollar Business Days' notice to the Agent,
subject to Section 2.13, prepay any Group of Euro-Dollar Loans, in whole at any
time, or from time to time in part in amounts aggregating $10,000,000 or any
larger multiple of $1,000,000, by paying the principal amount to be prepaid
together with accrued interest thereon to but not including the date of
prepayment. Each such optional prepayment shall be applied to prepay ratably the
Loans of the several Banks included in such Group of Loans (or such Money Market
Borrowing).

         (b) Except as provided in Section 2.11(a)(i), the Borrower may not
prepay all or any portion of the principal amount of any Money Market Loan prior
to the maturity thereof.

         (c) Upon receipt of a notice of prepayment pursuant to this Section,
the Agent shall promptly notify each Bank of the contents thereof and of such
Bank's ratable share (if any) of such prepayment and once notice is so given to
the Banks, the Borrower's notice of prepayment shall not thereafter be revocable
by the Borrower.

         SECTION 2.12. General Provisions as to Payments. (a) The Borrower shall
make each payment of principal of, and interest on, the Loans and of fees
hereunder, not later than 2:00 P.M. (New York City time) on the date when due,
in Federal or other funds immediately available in New York City, to the Agent
at its address referred to in Section 9.01. The Agent will promptly distribute
to each Bank its ratable share of each such payment received by the Agent for
the respective accounts of the Banks. Whenever any payment of principal of, or
interest on, the Domestic Loans or of fees shall be due on a day which is not a
Domestic Business Day, the date for payment thereof shall be extended to the
next succeeding Domestic


                                       27
<PAGE>   33
Business Day. Whenever any payment of principal of, or interest on, the
Euro-Dollar Loans shall be due on a day which is not a Euro-Dollar Business Day,
the date for payment thereof shall be extended to the next succeeding
Euro-Dollar Business Day unless such Euro-Dollar Business Day falls in another
calendar month, in which case the date for payment thereof shall be the next
preceding Euro-Dollar Business Day. Whenever any payment of principal of, or
interest on, the Money Market Loans shall be due on a day which is not a
Euro-Dollar Business Day, the date for payment thereof shall be extended to the
next succeeding Euro-Dollar Business Day. If the date for any payment of
principal is extended by operation of law or otherwise, interest thereon shall
be payable for such extended time.

         (b) Unless the Agent shall have received notice from the Borrower
prior to the date on which any payment is due to the Banks hereunder that the
Borrower will not make such payment in full, the Agent may assume that the
Borrower has made such payment in full to the Agent on such date and the Agent
may, in reliance upon such assumption, cause to be distributed to each Bank on
such due date an amount equal to the amount then due such Bank. If and to the
extent that the Borrower shall not have so made such payment, each Bank shall
repay to the Agent forthwith on demand such amount distributed to such Bank
together with interest thereon, for each day from the date such amount is
distributed to such Bank until the date such Bank repays such amount to the
Agent, at the Federal Funds Rate.

         SECTION 2.13. Funding Losses. If the Borrower makes any payment of
principal with respect to any Fixed Rate Loan or any Fixed Rate Loan is
converted to a different type of Loan (pursuant to Article 2, 6 or 8 (other than
Section 8.02)) on any day other than the last day of an Interest Period
applicable thereto, or the last day of an applicable period fixed pursuant to
Section 2.07(d), or if the Borrower fails to borrow, prepay, convert or continue
any Fixed Rate Loans after notice has been given to any Bank in accordance with
Section 2.04(a), 2.11(c) or 2.16 (other than as a result of default by such
Bank), the Borrower shall reimburse each Bank within 15 days after written
demand for any resulting loss or expense reasonably incurred by it (or by an
existing or prospective Participant in the related Loan) in obtaining,
liquidating or employing deposits from third parties, but excluding loss of
margin for the period after any such payment or conversion or failure to borrow,
prepay, convert or continue; provided that such Bank shall have delivered to the
Borrower a certificate specifying in reasonable detail the calculation of, and
the reasons for, the amount of such loss or expense, which certificate shall be
conclusive in the absence of manifest error.

         SECTION 2.14. Computation of Interest and Fees. Interest based on the
Prime Rate hereunder shall be computed on the basis of a year of 365 days (or
366 days in a leap year) and paid for the actual number of days elapsed
(including the first day but excluding the last day). All other interest and
fees shall be computed on the basis of a year of 360 days and paid for the
actual number of days elapsed (including the first day but excluding the last
day).

         SECTION 2.15. Regulation D Compensation. Each Bank may require the
Borrower to pay, contemporaneously with each payment of interest on the
Euro-Dollar Loans, additional interest on the related Euro-Dollar Loan of such
Bank at a rate per annum determined by such


                                       28
<PAGE>   34
Bank up to but not exceeding the excess of (i) (A) the applicable London
Interbank Offered Rate divided by (B) one minus the Euro-Dollar Reserve
Percentage over (ii) the applicable London Interbank Offered Rate. Any Bank
wishing to require payment of such additional interest (x) shall so notify the
Borrower and the Agent, in which case such additional interest on the
Euro-Dollar Loans of such Bank shall be payable to such Bank at the place
indicated in such notice with respect to each Interest Period commencing at
least three Euro-Dollar Business Days after the giving of such notice, and (y)
shall notify the Borrower at least five Euro-Dollar Business Days prior to each
date on which interest is payable on the Euro-Dollar Loans of the amount then
due it under this Section.

         "EURO-DOLLAR RESERVE PERCENTAGE" means for any day that percentage
(expressed as a decimal) which is in effect on such day, as prescribed by the
Board of Governors of the Federal Reserve System (or any successor) for
determining the maximum reserve requirement for a member bank of the Federal
Reserve System in New York City with deposits exceeding five billion dollars in
respect of "Eurocurrency liabilities" (or in respect of any other category of
liabilities which includes deposits by reference to which the interest rate on
Euro-Dollar Loans is determined or any category of extensions of credit or other
assets which includes loans by a non-United States office of any Bank to United
States residents).

         SECTION 2.16. Method of Electing Interest Rates. (a) The Loans included
in each Committed Borrowing shall bear interest initially at the type of rate
specified by the Borrower in the applicable Notice of Committed Borrowing.
Thereafter, the Borrower may from time to time elect to change or continue the
type of interest rate borne by each Group of Loans (subject to subsection
2.16(d) of this Section and the provisions of Article 8), as follows:

                  (i)   if such Loans are Base Rate Loans, the Borrower may 
         elect to convert such Loans to CD Loans as of any Domestic Business Day
         or to Euro-Dollar Loans as of any Euro-Dollar Business Day;

                  (ii)  if such Loans are CD Loans, the Borrower may elect to
         convert such Loans to Base Rate Loans or Euro-Dollar Loans or elect to
         continue such Loans as CD Loans for an additional Interest Period,
         subject to Section 2.13 if any such conversion is effective on any day
         other than the last day of an Interest Period applicable to such Loans;
         and

                  (iii) if such Loans are Euro-Dollar Loans, the Borrower may
         elect to convert such Loans to Base Rate Loans or CD Loans or elect to
         continue such Loans as Euro-Dollar Loans for an additional Interest
         Period, subject to Section 2.13 if any such conversion is effective on
         any day other than the last day of an Interest Period applicable to
         such Loans.

Each such election shall be made by delivering a notice (a "Notice of Interest
Rate Election") to the Agent not later than 10:30 A.M. (New York City time) on
the third Euro-Dollar Business Day before the conversion or continuation
selected in such notice is to be effective (unless the


                                       29
<PAGE>   35
relevant Loans are to be converted from Domestic Loans of one type to Domestic
Loans of the other type or are CD Loans to be continued as CD Loans for an
additional Interest Period, in which case such notice shall be delivered to the
Agent not later than 10:30 A.M. (New York City time) on the second Domestic
Business Day before such conversion or continuation is to be effective). A
Notice of Interest Rate Election may, if it so specifies, apply to only a
portion of the aggregate principal amount of the relevant Group of Loans;
provided that (i) such portion is allocated ratably among the Loans comprising
such Group and (ii) the portion to which such Notice applies, and the remaining
portion to which it does not apply, are each at least $10,000,000 (unless such
portion is comprised of Base Rate Loans). If no such notice is timely received
before the end of an Interest Period for any Group of CD Loans or Euro-Dollar
Loans, the Borrower shall be deemed to have elected that such Group of Loans be
converted to Base Rate Loans at the end of such Interest Period.

         (b) Each Notice of Interest Rate Election shall specify:

                  (i)   the Group of Loans (or portion thereof) to which such
         notice applies;

                  (ii)  the date on which the conversion or continuation 
         selected in such notice is to be effective, which shall comply with the
         applicable clause of subsection 2.16(a) above;

                  (iii) if the Loans comprising such Group are to be converted,
         the new type of Loans and, if the Loans resulting from such conversion
         are to be CD Loans or Euro-Dollar Loans, the duration of the next
         succeeding Interest Period applicable thereto; and

                  (iv)  if such Loans are to be continued as CD Loans or
         Euro-Dollar Loans for an additional Interest Period, the duration of
         such additional Interest Period.

Each Interest Period specified in a Notice of Interest Rate Election shall
comply with the provisions of the definition of Interest Period.

         (c) Promptly after receiving a Notice of Interest Rate Election from
the Borrower pursuant to subsection (a) above, the Agent shall notify each Bank
of the contents thereof and such notice shall not thereafter be revocable by the
Borrower.

         (d) The Borrower shall not be entitled to elect to convert any
Committed Loans to, or continue any Committed Loans for an additional Interest
Period as, CD Loans or Euro-Dollar Loans if (i) the aggregate principal amounts
of any Group of CD Loans or Euro-Dollar Loans created or continued as a result
of such election would be less than $10,000,000 or (ii) a Default shall have
occurred and be continuing when the Borrower delivers notice of such election to
the Agent.

                                    ARTICLE 4
                         REPRESENTATIONS AND WARRANTIES

                  The Borrower represents and warrants to the Agent and the
Banks that:

         SECTION 4.01. Corporate Existence and Power. The Borrower is a
corporation (in the case of Tyco US) or a company (in the case of Tyco
Luxembourg) duly incorporated and validly existing and (in the case of Tyco US)
in good standing under the laws of its jurisdiction of incorporation. The
Borrower has all corporate powers and all governmental licenses, authorizations,
consents and approvals (collectively, the "Consents") required to carry on its
business as now conducted, other than those powers and Consents, the failure of
which to be


                                       36
<PAGE>   42
possessed or obtained could not, based upon the facts and circumstances in
existence at the time this representation and warranty is made or deemed made,
reasonably be expected to have a Material Adverse Effect.

         SECTION 4.02. Corporate and Governmental Authorization; No
Contravention. The execution, delivery and performance by the Borrower of this
Agreement and the Promissory Notes: (a) are within the Borrower's corporate
powers; (b) have been duly authorized by all necessary corporate action on the
part of the Borrower; (c) require no action by or in respect of, or filing with,
any governmental body, agency or official, in each case, on the part of the
Borrower; and (d) do not contravene, or constitute a default by the Borrower
under, any provision of (i) applicable law or regulation, (ii) the
organizational documents of the Borrower, or (iii) any agreement or instrument
evidencing or governing Debt of the Borrower or any other material agreement,
judgment, injunction, order, decree or other instrument binding upon the
Borrower.

         SECTION 4.03. Binding Effect. This Agreement constitutes a valid and
binding agreement of the Borrower and the Promissory Notes, when executed and
delivered in accordance with this Agreement, will constitute valid and binding
obligations of the Borrower.

         SECTION 4.04.  Financial Information.

         (a) The consolidated balance sheet of the Borrower and its Consolidated
Subsidiaries as of June 30, 1997 and the related consolidated statements of
income, of shareholders' equity and of cash flows for the fiscal year then
ended, reported on by Coopers & Lybrand L.L.P., copies of which have been
delivered to each of the Banks, fairly present, in conformity with generally
accepted accounting principles, the consolidated financial position of the
Borrower and its Consolidated Subsidiaries as of such date and their
consolidated results of operations and cash flows for such fiscal year.

         (b) Since June 30, 1997 there has been no material adverse change in
the business, financial position, results of operations or Prospects of the
Borrower and its Consolidated Subsidiaries, considered as a whole.

         SECTION 4.05. Litigation. There is no action, suit or proceeding
pending against, or to the knowledge of the Borrower threatened against or
affecting, the Borrower or any of its Subsidiaries before any court or
arbitrator or any governmental body, agency or official in which there is a
reasonable possibility of an adverse decision which could, based upon the facts
and circumstances in existence at the time this representation and warranty is
made or deemed made, reasonably be expected to have a Material Adverse Effect or
which in any manner draws into question the validity of the Financing Documents.

         SECTION 4.06. Compliance with ERISA. Each member of the ERISA Group has
fulfilled its obligations under the minimum funding standards of ERISA and the
Internal Revenue Code with respect to each Plan and is in compliance, except
where the failure to so comply could not,


                                       37
<PAGE>   43
based upon the facts and circumstances in existence at the time this
representation and warranty is made or deemed made, reasonably be expected to
have a Material Adverse Effect, with the presently applicable provisions of
ERISA and the Internal Revenue Code with respect to each Plan. No member of the
ERISA Group has (i) sought a waiver of the minimum funding standard under
Section 412 of the Internal Revenue Code in respect of any Plan, (ii) failed to
make any required contribution or payment to any Plan or Multiemployer Plan, or
made any amendment to any Plan, which has resulted in or could, based upon the
facts and circumstances in existence at the time this representation and
warranty is made or deemed made, reasonably be expected to result in the
imposition of a Lien or the posting of a bond or other security under ERISA or
the Internal Revenue Code or (iii) incurred any liability under Title IV of
ERISA (other than a liability to the PBGC for premiums under Section 4007 of
ERISA), which could, based upon the facts and circumstances existing at the time
this representation and warranty is made or deemed made, reasonably be expected
to have a Material Adverse Effect.

         SECTION 4.07. Environmental Matters. In the ordinary course of its
business, the Borrower conducts an ongoing review of the effect of Environmental
Laws on the business, operations and properties of the Borrower and its
Subsidiaries, in the course of which it identifies and evaluates associated
liabilities and costs (including, without limitation, any capital or operating
expenditures required for clean-up or closure of properties presently or
previously owned, any capital or operating expenditures required to achieve or
maintain compliance with environmental protection standards imposed by law or as
a condition of any license, permit or contract, any related constraints on
operating activities, including any periodic or permanent shutdown of any
facility or reduction in the level of or change in the nature of operations
conducted thereat, any costs or liabilities in connection with off-site disposal
of wastes or Hazardous Substances, and any actual or potential liabilities to
third parties, including employees, and any related costs and expenses). On the
basis of this review, the Borrower has reasonably concluded that such associated
liabilities and costs, including the costs of compliance with Environmental
Laws, could not, based upon the facts and circumstances existing at the time
this representation and warranty is made or deemed made, reasonably be expected
to have a Material Adverse Effect.

         SECTION 4.08. Taxes. The Borrower and its Subsidiaries have filed all
United States Federal income tax returns and all other material tax returns
which are required to be filed by them and have paid all taxes shown on such
returns or pursuant to any assessment received by the Borrower or any
Subsidiary, except those assessments which are being contested in good faith by
appropriate proceedings. The charges, accruals and reserves on the books of the
Borrower and its Subsidiaries in respect of taxes or other governmental charges
are, in the opinion of the Borrower, adequate.

         SECTION 4.09. Subsidiaries. Each of the Borrower's corporate
Consolidated Subsidiaries is a corporation duly incorporated, validly existing
and in good standing under the laws of its jurisdiction of incorporation, except
where the failure to be so incorporated, existing or in good standing could not,
based upon the facts and circumstances existing at the time this representation
and warranty is made or deemed made, reasonably be expected to have a Material


                                       38
<PAGE>   44
Adverse Effect. Each such Subsidiary has all corporate powers and all Consents
required to carry on its business as now conducted, other than those powers and
Consents, the failure of which to be possessed or obtained could not, based upon
the facts and circumstances in existence at the time this representation and
warranty is made or deemed made, reasonably be expected to have a Material
Adverse Effect.

         SECTION 4.10. Not an Investment Company. The Borrower is not an
"investment company" within the meaning of the Investment Company Act of 1940,
as amended.

         SECTION 4.11. Full Disclosure. The factual information, reports,
financial statements, exhibits and schedules concerning the Borrower and its
Subsidiaries furnished by or on behalf of the Borrower and contained in the
Confidential Information Memorandum dated January 1998 furnished by J.P. Morgan
Securities Inc. to a limited number of banks which were being invited to
participate in this Agreement, do not contain any untrue statement of material
fact or omit to state any material fact necessary to make the statements
contained herein or therein, in light of the circumstances under which they were
made, not misleading.

                                    ARTICLE 5

                                    COVENANTS

Subsidiaries as the Agent, at the request of any Bank, may reasonably request.

         SECTION 5.02. Payment of Obligations. The Borrower will pay and
discharge, and will cause each Subsidiary to pay and discharge, at or before
maturity, all their respective material obligations and liabilities, including,
without limitation, tax liabilities, except where (i) any such failure to so pay
or discharge could not, based upon the facts and circumstances in existence at
the time, reasonably be expected to have a Material Adverse Effect or (ii) such
liabilities or obligations may be contested in good faith by appropriate
proceedings. The Borrower will maintain, and will cause each Subsidiary to
maintain, in accordance with generally accepted accounting principles,
appropriate reserves for the accrual of any of such liabilities or obligations.

unless the failure to so keep could not, based upon the facts and circumstances
existing at the time, reasonably be expected to have a Material Adverse Effect.

         (b) The Borrower will maintain, and will cause each Subsidiary to
maintain, with financially sound and reputable insurers, insurance with respect
to its assets and business against such casualties and contingencies, of such
types (including, without limitation, loss or damage, product liability,
business interruption, larceny, embezzlement or other criminal misappropriation)
and in such amounts as is customary in the case of similarly situated
corporations of established reputations engaged in the same or a similar
business, unless the failure to maintain such insurance could not, based upon
the facts and circumstances existing at the time, reasonably be expected to have
a Material Adverse Effect.

         SECTION 5.04. Conduct of Business and Maintenance of Existence. The
Borrower (a) will continue, and will cause each Subsidiary to continue, to
engage in business of the same general type as now conducted by the Borrower and

preserve, renew and keep in full force and effect, and will cause each
Subsidiary to preserve, renew and keep in full force and effect (x) their
respective corporate existence and (y) their respective rights, privileges and
franchises necessary or desirable in the normal conduct of business, unless in
the case of either the failure of the Borrower to comply with subclause (b) (y)
of this Section 5.04 or the failure of a Subsidiary to comply with clauses (a)
or (b) of this Section 5.04, such failure could not, based upon the facts and
circumstances existing at the time, reasonably be expected to have a Material
Adverse Effect; provided that nothing in this Section 5.04 shall prohibit (i)
the merger or consolidation of a Subsidiary with or into the Borrower or a
Wholly-Owned Consolidated Subsidiary, (ii) the sale, lease, transfer, assignment
or other disposition by a Subsidiary of all or any part of its assets to the
Borrower or to a Wholly-Owned Consolidated Subsidiary, (iii) the merger or
consolidation of a Subsidiary with or into a Person other than the Borrower or a
Wholly-Owned Consolidated Subsidiary, if the Person surviving such consolidation
or merger is a Subsidiary and immediately after giving effect thereto, no
Default shall have occurred and be continuing, (iv) the sale, lease, transfer,
assignment or other disposition by a Subsidiary of all or any part of its assets
to a Person other than the Borrower or a Wholly-Owned Consolidated Subsidiary if
the Person to which such sale, lease, transfer, assignment or other disposition
is made is a Subsidiary and immediately after giving effect thereto, no Default
shall have occurred and be continuing, (v) any transaction permitted pursuant to
Section 5.11, (vi) the termination of the corporate existence of any Subsidiary
if the Borrower in good faith determines that such termination is in the best
interest of the Borrower and is not materially disadvantageous to the Banks and
(vii) the sale, lease, transfer, assignment or other disposition (including any
such transaction by way of merger or consolidation) by the Borrower of all or
any part of its assets to a Person other than the Borrower or a Subsidiary if
(A) immediately after giving effect thereto, no Default shall have occurred and
be continuing and (B) the Borrower is a Subsidiary of such Person or the
Borrower and such Person are Subsidiaries of the same Person.

ordinances, rules,


                                       42
<PAGE>   48
regulations, and requirements of governmental authorities (including, without
limitation, Environmental Laws and ERISA and the rules and regulations
thereunder) except where (a) noncompliance therewith could not, based upon the
facts and circumstances in existence at the time, reasonably be expected to have
a Material Adverse Effect or (b) the necessity of compliance therewith is
contested in good faith by appropriate proceedings.

         SECTION 5.06. Inspection of Property, Books and Records;
Confidentiality. (a) The Borrower will keep, and will cause each Subsidiary to
keep, proper books of record and account in which true and correct entries shall
be made of its business transactions and activities so that financial statements
that fairly present its business transactions and activities can be properly
prepared in accordance with generally accepted accounting principles.

         (b) The Borrower will permit, and will cause each Subsidiary to permit,
representatives of any Bank at such Bank's expense to visit and inspect any of
their respective properties, to examine and make abstracts from any of their
respective books and records and to discuss their respective affairs, finances
and accounts with their respective officers, employees and independent public
accountants, all upon reasonable notice to the Borrower, at such reasonable
times and as often as may reasonably be requested by any Bank.

         (c) Each Bank and the Agent shall, by its receipt of Confidential
Information (as defined below) pursuant to or in connection with this Agreement
or its exercise of any of its rights hereunder, be deemed to have agreed (on
behalf of itself and each of its affiliates, directors, officers, employees and
representatives) to (i) keep such information confidential, (ii) (except as
permitted by clause (iii) of this Section 5.06(c)) not disclose such information
to any Person other than an officer, director, employee, legal counsel,
independent auditor or authorized agent or advisor of the Agent or such Bank
needing to know such information (it being understood that any such officer,
director, employee, legal counsel, independent auditor or authorized agent or
advisor shall be informed by the Agent or such Bank of the confidential nature
of such information), (iii) not disclose such information to any Assignee or
Participant (or prospective Assignee or Participant), unless such Assignee or
Participant (or prospective Assignee or Participant) shall agree in writing to
be bound by the provisions of this Section 5.06(c) and (iv) not use any such
information except for purposes relating to this Agreement or the Notes. The
term "Confidential Information" shall mean non-public information furnished by
or on behalf of the Borrower or any of its Subsidiaries to the Agent, any Bank
or other Person exercising rights hereunder or required to be bound hereby
(collectively "Recipients"), but shall not include any such information which
(1) has become or hereafter becomes available to the public other than as a
result of a disclosure by a Recipient, or (2) has become or hereafter becomes
available to a Recipient, on a non-confidential basis, from a source other than
the Borrower or any of its Subsidiaries (or any of their respective
representatives or agents) or any Recipient, which source, to the knowledge of
the Recipient, is not prohibited from disclosing such information by a
confidentiality agreement with, or other legal or fiduciary obligation to, the
Borrower or its Subsidiaries.


                                       43
<PAGE>   49
         The restrictions set forth in the immediately preceding paragraph shall
not prevent the disclosure by a Recipient of any such information:

                  such order and not effectively stayed on appeal or otherwise,
                  or as otherwise required by law; provided that in the case of
                  any intended disclosure under this clause (C), the Recipient
                  shall (unless otherwise required by applicable law) give the
                  Borrower not less than five Domestic Business Days prior
                  notice (or such shorter period as may, in the good faith
                  discretion of the Recipient, be reasonable under the
                  circumstances or may be required by any court or agency under
                  the circumstances), specifying the Confidential Information
                  involved and stating such Recipient's intention to disclose
                  such Confidential Information (including the manner and extent
                  of such disclosure) in order to allow the Borrower an
                  opportunity to seek an appropriate protective order.

         Each Recipient shall agree that, in addition to all other remedies
available, the Borrower shall be entitled to specific performance and injunctive
and other equitable relief as a remedy for any breach of this Section 5.06(c) by
such Recipient.

         SECTION 5.07. Limitation on Restrictions on Subsidiary Dividends and
Other Distributions. The Borrower will not, and will not permit any Subsidiary
to, directly or indirectly, create or otherwise cause or suffer to exist or
become effective any encumbrance or restriction on the ability of any Subsidiary
to (a) pay dividends or make any other distributions on its capital stock or any
other interest or participation in its profits, owned by the Borrower or any
Subsidiary, or pay any Debt owed to the Borrower or any Subsidiary, (b) make
loans or advances to the Borrower or any Subsidiary or (c) transfer any of its

         or a Subsidiary, or (B) customary restrictions imposed on the transfer
         of copyrighted or patented materials or provisions in agreements that
         restrict the assignment of such agreements or any rights thereunder,


                                       44

         existing on the Effective Date,

                  (v)      provisions contained in documents evidencing or
         governing any Permitted Receivables Transaction,

                  (vi)     provisions contained in instruments evidencing or
         governing Debt or other obligations or agreements of any Person, in
         each case, at the time such Person (A) shall be merged or consolidated
         with or into the Borrower or any Subsidiary, (B) shall sell, transfer,
         assign, lease or otherwise dispose of all or substantially all of such
         Person's assets to the Borrower or a Subsidiary, or (C) otherwise
         becomes a Subsidiary, provided that in the case of clause (A), (B) or
         (C), such Debt, obligation or agreement was not incurred or entered
         into, or any such provisions adopted, in contemplation of such
         transaction,

         restating, supplementing, extending, renewing, refunding, refinancing,
         replacing or otherwise modifying, in whole or in part (collectively,
         "Refinancing"), instruments referred to in clauses (ii), (iv) and (vi)
         of this Section 5.07, so long as such provisions are, in the good faith
         determination of the Borrower's board of directors, not materially more
         restrictive than those contained in the respective instruments so
         Refinanced,

                  (viii)   provisions contained in any instrument evidencing or
         governing Debt or other obligations of a Subsidiary Guarantor,

                  (ix)     any encumbrances and restrictions with respect to a
         Subsidiary imposed in connection with an agreement which has been
         entered into for the sale or disposition of such Subsidiary or its
         assets, provided such sale or disposition otherwise complies with this
         Agreement,

                  (x)      the subordination (pursuant to its terms) in right
         and priority of payment of any Debt owed by any Subsidiary (the
         "Indebted Subsidiary") to the Borrower or any other Subsidiary, to any
         other Debt of such Indebted Subsidiary, provided (A) such Debt is
         permitted under this Agreement and (B) the Borrower's board of
         directors has determined, in good faith, at the time of the creation of
         such encumbrance or restriction, that such encumbrance or restriction
         could not, based upon the facts and circumstances in existence at the
         time, reasonably be expected to have a Material Adverse Effect,

                  (xi)     provisions governing preferred stock issued by a

                                       45
<PAGE>   51
         this Section 5.07, provided that the aggregate investment of the
         Borrower in all such Subsidiaries (determined in accordance with
         generally accepted accounting principles) shall at no time exceed the
         greater of (a) $300,000,000 or (b) 10% of Consolidated Tangible Net

held by a Person other than the Borrower or a Wholly-Owned Consolidated
Subsidiary shall be included, at the higher of its voluntary or involuntary
liquidation value, in "Consolidated Debt" and in the "Debt" of such Consolidated
Subsidiary.

         SECTION 5.09. Fixed Charge Coverage. The ratio of Consolidated EBIT to
Consolidated Interest Expense will not, for any period of four consecutive
fiscal quarters, be less than 2.5 to 1.

         SECTION 5.10. Negative Pledge. Neither the Borrower nor any Subsidiary

hereafter acquired by it, except:

         (a)      any Lien existing on any asset on the Effective Date securing
Debt outstanding on the Effective Date;

         (b)      any Lien existing on any asset of, or capital stock of, or
other ownership interest in, any Person (such capital stock and other ownership
interests are collectively referred to herein as "Stock") at the time such
Person becomes a Subsidiary, which Lien was not created in contemplation of such
event;

         (c)      any Lien on any asset securing the payment of all or part of
the purchase price of such asset upon the acquisition thereof by the Borrower or
a Subsidiary or securing Debt (including any obligation as lessee incurred under
a capital lease) incurred or assumed by the Borrower or a Subsidiary prior to,
at the time of or within one year after such acquisition (or in the case of real
property, the completion of construction (including any improvements on an
existing property) or the commencement of full operation of such asset or
property, whichever is later), which Debt is incurred or assumed for the purpose
of financing all or part of the cost of acquiring such asset or, in the case of
real property, construction or improvements thereon; provided, that in the case
of any such acquisition, construction or improvement, the Lien shall


                                       46
<PAGE>   52
not apply to any asset theretofore owned by the Borrower or a Subsidiary, other
than assets so acquired, constructed or improved;

         (d)      any Lien existing on any asset or Stock of any Person at the
time such Person is merged or consolidated with or into the Borrower or a
Subsidiary which Lien was not created in contemplation of such event;

         (e)      any Lien existing on any asset or Stock of any Person at the
time of acquisition thereof by the Borrower or a Subsidiary, which Lien was not
created in contemplation of such acquisition;

         (f)      any Lien arising out of the Refinancing of any Debt secured by
any Lien permitted by any of the subsections (a) through (e) of this Section
5.10, provided the principal amount of Debt is not increased and is not secured
by any additional assets, except as provided in the last sentence of this
Section 5.10;

         (g)      any Lien to secure Debt of a Subsidiary to the Borrower or to
a Wholly-Owned Consolidated Subsidiary;

         (h)      any Lien created pursuant to a Permitted Receivables
Transaction;

         (i)      any Lien in favor of the United States or any other country
(or any department, agency, instrumentality or political subdivision of the
United States or any other country) securing obligations arising in connection
with partial, progress, advance or other payments pursuant to any contract,
statute, rule or regulation or securing obligations incurred for the purpose of
financing all or any part of the purchase price (including the cost of
installation thereof or, in the case of real property, the cost of construction
or improvement or installation of personal property thereon) of the asset
subject to such Lien (including, but not limited to, any Lien incurred in
connection with pollution control, industrial revenue or similar financings);

         (j)      Liens arising in the ordinary course of its business which (i)
do not secure Debt, (ii) do not secure any single obligation in an amount
exceeding $50,000,000 and (iii) do not in the aggregate materially detract from
the value of its assets or materially impair the use thereof in the operation of
its business; and

         (k)      Liens not otherwise permitted by the foregoing clauses (a)
through (j) of this Section 5.10 securing Debt (without duplication) in an
aggregate principal amount at any time outstanding not to exceed an amount equal
to the greater of (i) $300,000,000 or (ii) 10% of Consolidated Tangible Net
Worth.

It is understood that any Lien permitted to exist on any asset pursuant to the
foregoing provisions of this Section 5.10 may attach to the proceeds of such
asset and, with respect to Liens permitted pursuant to subsections (a), (b),
(d), (e), (f) (but only with respect to the Refinancing of a Debt secured by a
Lien permitted pursuant to subsections (a), (b), (d) or (e)) or (g) of this
Section 5.10,


                                       47
<PAGE>   53
may attach to an asset acquired in the ordinary course of business as a
replacement of such former asset.

Borrower will not (i) consolidate or merge with or into any other Person or (ii)
sell, lease or otherwise transfer all or substantially all of its assets to any
other Person, unless

                  of Tyco US) a Domestic Parent is the surviving corporation;

                           (B)      the Person (if other than the Borrower)
                  formed by such consolidation or into which the Borrower is
                  merged, or the Person which acquires by sale or other
                  transfer, or which leases, all or substantially all of the
                  assets of the Borrower (any such Person, the "Successor"),
                  shall be organized and existing under the laws of (x) in the
                  case of Tyco US, the United States, any state thereof or the
                  District of Columbia and (y) in the case of Tyco Luxembourg,
                  Luxembourg, and shall expressly assume, in a writing executed
                  and delivered to the Agent for delivery to each of the Banks,
                  in form reasonably satisfactory to the Agent, the due and
                  punctual payment of the principal of and interest on the
                  Promissory Notes and the performance of the other obligations
                  under this Agreement and the Promissory Notes on the part of
                  the Borrower to be performed or observed, as fully as if such
                  Successor were originally named as the Borrower in this
                  Agreement;

                           (C)      immediately after giving effect to such
                  transaction, no Default shall have occurred and be continuing;
                  and

                           (D)      the Borrower has delivered to the Agent a
                  certificate on behalf of the Borrower signed by a Responsible
                  Officer and an opinion of counsel (which counsel may be an
                  employee of the Borrower), each stating that all conditions
                  provided in this Section 5.11 relating to such transaction
                  have been satisfied.

         The foregoing provisions of this Section 5.11 shall not restrict the
merger or consolidation of any Subsidiary with and into the Borrower.

         Upon the satisfaction (or waiver in accordance with Section 9.05) of
the conditions set forth in this Section 5.11, the Successor shall succeed, and
may exercise every right and power of, the Borrower under this Agreement and the
Promissory Notes with the same effect as if the Successor had been originally
named as the Borrower herein and in the Promissory Notes, and the Borrower shall
be relieved of its obligations under this Agreement and the Promissory Notes.

         (b)      The Borrower will not, and will not permit any Subsidiary to,
sell, lease or otherwise transfer, in any transaction or series of related
transactions, to any Person (other than the Borrower, a Subsidiary, a Person of
which the Borrower is a Subsidiary or a Subsidiary of such a Person) any
Property (including, without limitation, the stock of any Subsidiary) having a


                                       48
<PAGE>   54
net book value in excess of 15% of Consolidated Assets determined as of the end
of the fiscal quarter of the Borrower most recently ended at the time of such
sale or other transaction, or Property (including without limitation, stock of a
Subsidiary) which contributed in excess of 15% of Consolidated EBIT for the
fiscal year of the Borrower most recently ended at the time of such sale or
other transaction.

         SECTION 5.12. Use of Proceeds. The proceeds of the Loans made under
this Agreement will be used by the Borrower for its general corporate purposes,
including, without limitation, capital expenditures and (subject to the
following sentence) acquisitions. None of such proceeds will be used, directly
or indirectly, for the purpose, whether immediate, incidental or ultimate, of
buying or carrying any "margin stock" within the meaning of Regulation U.

         SECTION 5.13. Transactions with Affiliates. The Borrower will not, and
will not permit any Subsidiary to, directly or indirectly, pay any funds to or
for the account of, make any investment (whether by acquisition of stock or
indebtedness, by loan, advance, transfer of property, guarantee or other
agreement to pay, purchase or service, directly or indirectly, any Debt, or
otherwise) in, lease, sell, transfer or otherwise dispose of any assets,
tangible or intangible, to, or participate in, or effect any transaction in
connection with any joint enterprise or other joint arrangement with, any
Affiliate (collectively, "AFFILIATE TRANSACTIONS"); provided, however, that the
foregoing provisions of this Section 5.13 shall not prohibit the Borrower or any
of its Subsidiaries from: (a) making sales to or purchases from any Affiliate
and, in connection therewith, extending credit or making payments, or from
making payments for services rendered by any Affiliate, if such sales or
purchases are made or such services are rendered in the ordinary course of

expect to be obtained in a similar transaction with a Person which is not an
Affiliate at such time, (b) making payments of principal, interest and premium
on any Debt of the Borrower or such Subsidiary held by an Affiliate if the terms
of such Debt are at least as favorable to the Borrower or such Subsidiary as the
terms which the Borrower would reasonably expect to have been obtained at the
time of the creation of such Debt from a lender which was not an Affiliate, (c)
participating in, or effecting any transaction in connection with, any joint
enterprise or other joint arrangement with any Affiliate if the Borrower or such
Subsidiary participates in the ordinary course of its business and on a basis no
less advantageous than the basis on which such Affiliate participates, (d)
paying or granting reasonable compensation and benefits to any director,
officer, employee or agent of the Borrower or any Subsidiary, (e) paying
reasonable legal fees and expenses to a law firm of which an Affiliate is a
member or (f) engaging in any Affiliate Transaction not otherwise addressed in
subsections (a) - (e) of this Section 5.13, the consummation of which could not
reasonably be expected to have a Material Adverse Effect.

         SECTION 5.14. Additional Subsidiary Guarantors. If, subsequent to the
New Borrower Date, any Person shall become a Required Significant Subsidiary of
the Borrower, the Borrower shall cause such Person to become a Subsidiary
Guarantor within 30 days after such Person became a Significant Subsidiary of
the Borrower.

                                    ARTICLE 7

                                    THE AGENT

         SECTION 7.01. Appointment and Authorization. Each Bank irrevocably
appoints and authorizes the Agent to take such action as agent on its behalf and
to exercise such powers under the Financing Documents as are delegated to the
Agent by the terms hereof or thereof, together with all such powers as are
reasonably incidental thereto.

         SECTION 7.02. Agent and Affiliates. Morgan Guaranty Trust Company of
New York (and any successor acting as Agent) in its capacity as a Bank hereunder
shall have the same rights and powers under the Financing Documents as any other
Bank and may exercise or refrain from exercising the same as though it were not
the Agent, and Morgan Guaranty Trust Company of New York (and any successor
acting as Agent) and its affiliates may accept deposits from, lend money to, and
generally engage in any kind of business with the Borrower or any Subsidiary or
affiliate of the Borrower as if it were not the Agent hereunder.

         SECTION 7.03. Action by Agent. The obligations of the Agent under the
Financing Documents are only those expressly set forth therein. Without limiting
the generality of the foregoing, the Agent shall not be required to take any
action with respect to any Default, except as expressly provided in Article 6.


                                       52
<PAGE>   58
         SECTION 7.04. Consultation with Experts. The Agent may consult with
legal counsel (who may be counsel for the Borrower), independent public
accountants and other experts selected by it and shall not be liable for any
action taken or omitted to be taken by it in good faith in accordance with the
advice of such counsel, accountants or experts.

         SECTION 7.05. Liability of Agent. Neither the Agent nor any of its
affiliates nor any of their respective directors, officers, agents or employees
shall be liable for any action taken or not taken by it in connection herewith
(i) with the consent or at the request of the Required Banks or (ii) in the
absence of its own gross negligence or willful misconduct. Neither the Agent nor
any of its affiliates nor any of their respective directors, officers, agents or
employees shall be responsible for or have any duty to ascertain, inquire into
or verify (i) any statement, warranty or representation made in connection with
this Agreement or any borrowing hereunder; (ii) the performance or observance of
any of the covenants or agreements of the Borrower or any Guarantor; (iii) the
satisfaction of any condition specified in Article 3, except receipt of items
required to be delivered to the Agent; or (iv) the validity, effectiveness or
genuineness of this Agreement, the Subsidiary Guarantees, the Parent Guarantee,
the Promissory Notes or any other instrument or writing furnished in connection
herewith. The Agent shall not incur any liability by acting in reliance upon any
notice, consent, certificate, statement, or other writing (which may be a bank
wire, telex or similar writing) believed by it in good faith to be genuine or to
be signed by or on behalf of the proper party or parties. Without limiting the
generality of the foregoing, the use of the term "agent" in this Agreement with
reference to the Agent is not intended to connote any fiduciary or other implied
(or express) obligations arising under agency doctrine of any applicable law.
Instead, such term is used merely as a matter of market custom and is intended
to create or reflect only an administrative relationship between independent
contracting parties.

         SECTION 7.06. Indemnification. Each Bank shall, ratably in accordance
with its Commitment, indemnify the Agent, its affiliates and their respective
directors, officers, agents and employees (to the extent not reimbursed by the
Borrower) against any cost, expense (including counsel fees and disbursements),
claim, demand, action, loss or liability (except such as result from such
indemnitees' gross negligence or willful misconduct) that such indemnitees may
suffer or incur in connection with the Financing Documents or any action taken
or omitted by such indemnitees thereunder.

         SECTION 7.07. Credit Decision. Each Bank acknowledges that it has,
independently and without reliance upon the Agent or any other Bank, and based
on such documents and information as it has deemed appropriate, made its own
credit analysis of the Borrower and its Subsidiaries and its own decision to
enter into this Agreement. Each Bank also acknowledges that it will,
independently and without reliance upon the Agent or any other Bank, and based
on such documents and information as it shall deem appropriate at the time,
continue to make its own credit decisions in taking or not taking any action
under this Agreement.

         SECTION 7.08. Successor Agent. The Agent may resign at any time by
giving notice thereof to the Banks and the Borrower. Upon any such resignation,
the Required Banks shall have the right to appoint a successor Agent, subject to
the consent of the Borrower. If no


                                       53
<PAGE>   59
successor Agent shall have been so appointed by the Required Banks and consented
to by the Borrower and shall have accepted such appointment within 45 days after
the retiring Agent gives notice of resignation, then the retiring Agent may, on
behalf of the Banks, appoint a successor Agent, which shall be a commercial bank
organized or licensed under the laws of the United States of America or of any
State thereof and having a combined capital and surplus of at least $50,000,000.
Upon the acceptance of its appointment as Agent hereunder by a successor Agent,
such successor Agent shall thereupon succeed to and become vested with all the
rights, powers, privileges and duties of the retiring Agent, and the retiring
Agent shall be discharged from its duties and obligations under the Financing
Documents. After any retiring Agent's resignation hereunder as Agent, the
provisions of this Article shall inure to its benefit as to any actions taken or
omitted to be taken by it while it was acting as the Agent.

         SECTION 7.09. Agent's Fee. The Borrower shall pay to the Agent for its
own account fees in the amounts and at the times previously agreed upon in
writing between the Borrower and the Agent.


                                    ARTICLE 8

                             CHANGE IN CIRCUMSTANCES

         SECTION 8.01. Basis for Determining Interest Rate Inadequate or Unfair.
If on or prior to the first day of any Interest Period for any CD Loan,
Euro-Dollar Loan or Money Market LIBOR Loan:

         (a)      the Agent is advised by the Reference Banks that deposits in
dollars (in the applicable amounts) are not being offered to the Reference Banks
in the relevant market for such Interest Period, or

         (b)      in the case of CD Loans or Euro-Dollar Loans, Banks holding
50% or more of the aggregate amount of the affected Loans advise the Agent that
the Adjusted CD Rate or the London Interbank Offered Rate, as the case may be,
as determined by the Agent will not adequately and fairly reflect the cost to
such Banks of funding their CD Loans or Euro-Dollar Loans, as the case may be,
for such Interest Period,

the Agent shall forthwith give notice thereof to the Borrower and the Banks,
whereupon, until the Agent notifies the Borrower that the circumstances giving
rise to such suspension no longer exist (which the Agent agrees to do promptly
upon such circumstances ceasing to exist), (i) the obligations of the Banks to
make CD Loans or Euro-Dollar Loans, as the case may be, or to continue or
convert outstanding Loans as or into CD Loans or Euro-Dollar Loans, as the case
may be, shall be suspended and (ii) each outstanding CD Loan or Euro-Dollar
Loan, as the case may be, shall be converted into a Base Rate Loan on the last
day of the then current Interest Period applicable thereto. Unless the Borrower
notifies the Agent at least one Domestic Business Day before the date of any
Fixed Rate Borrowing for which a Notice of Borrowing has


                                       54
<PAGE>   60
previously been given that it elects not to borrow on such date, (i) if such
Fixed Rate Borrowing is a Committed Borrowing, such Borrowing shall instead be
made as a Base Rate Borrowing and (ii) if such Fixed Rate Borrowing is a Money
Market LIBOR Borrowing, the Money Market LIBOR Loans comprising such Borrowing
shall bear interest for each day from and including the first day to but
excluding the last day of the Interest Period applicable thereto at the Base
Rate for such day.

         SECTION 8.02. Illegality. If, on or after the date of this Agreement,
any Bank has determined in its reasonable judgment that the adoption of any
applicable law, rule or regulation, or any change in any applicable law, rule or
regulation, or any change in the interpretation or administration thereof by any
governmental authority, central bank or comparable agency charged with the
interpretation or administration thereof, or compliance by any Bank (or its
Euro-Dollar Lending Office) with any request or directive (whether or not having
the force of law) of any such authority, central bank or comparable agency,
shall make it unlawful or impossible for such Bank (or its Euro-Dollar Lending
Office) to make, maintain or fund its Euro-Dollar Loans and such Bank shall so
notify the Agent, the Agent shall forthwith give notice specifying the
circumstances giving rise to such suspension to the other Banks and the
Borrower, whereupon, until such Bank notifies the Borrower and the Agent that
the circumstances giving rise to such suspension no longer exist (which such
Bank agrees to do promptly upon such circumstances ceasing to exist), the
obligation of such Bank to make Euro-Dollar Loans, or to continue or convert
outstanding Loans as or into Euro-Dollar Loans, shall be suspended. Before
giving any notice to the Agent pursuant to this Section, such Bank shall
designate a different Euro-Dollar Lending Office if such designation will avoid
the need for giving such notice and will not, in the judgment of such Bank in
the good faith exercise of its discretion, be otherwise disadvantageous to such
Bank. If such notice is given, each Euro-Dollar Loan of such Bank then
outstanding shall be converted to a Base Rate Loan either (a) on the last day of
the then current Interest Period applicable to such Euro-Dollar Loan if such
Bank may lawfully continue to maintain and fund such Loan as a Euro-Dollar Loan
to such day or (b) immediately if such Bank shall determine that it may not
lawfully continue to maintain and fund such Loan as a Euro-Dollar Loan to such
day.

         SECTION 8.03. Increased Cost and Reduced Return. (a) If on or after (x)
the date of this Agreement, in the case of any Committed Loan or any obligation
to make Committed Loans or (y) the date of the related Money Market Quote, in
the case of any Money Market Loan, any Bank has determined in its reasonable
judgment that the adoption of any applicable law, rule or regulation, or any
change in any applicable law, rule or regulation, or any change in the
interpretation or administration thereof by any governmental authority, central
bank or comparable agency charged with the interpretation or administration
thereof, or compliance by any Bank (or its Applicable Lending Office) with any
request or directive (whether or not having the force of law) of any such
authority, central bank or comparable agency, shall impose, modify or deem
applicable any reserve (including, without limitation, any such requirement
imposed by the Board of Governors of the Federal Reserve System, but excluding
(i) with respect to any CD Loan any such requirement included in an applicable
Domestic Reserve Percentage and (ii) with respect to any Euro-Dollar Loan any
such requirement with respect to which such Bank is

                                       55
<PAGE>   61
entitled to compensation during the relevant Interest Period under Section
2.15), special deposit, insurance assessment (excluding, with respect to any CD
Loan, any such requirement reflected in an applicable Assessment Rate) or
similar requirement against assets of, deposits with or for the account of, or
credit extended by, such Bank (or its Applicable Lending Office) or shall impose
on any Bank (or its Applicable Lending Office) or on the United States market
for certificates of deposit or the London interbank market any other condition
affecting its Fixed Rate Loans, its Promissory Note or its obligation to make
Fixed Rate Loans and the result of any of the foregoing is to increase the cost
to such Bank (or its Applicable Lending Office) of making or maintaining any
Fixed Rate Loan, or to reduce the amount of any sum received or receivable by
such Bank (or its Applicable Lending Office) under this Agreement or under its
Promissory Note with respect thereto, by an amount deemed by such Bank to be
material to such Bank, then, within 15 days after written demand by such Bank
(with a copy to the Agent), the Borrower shall pay to such Bank such additional
amount or amounts as will compensate such Bank for such increased cost or
reduction.

          (b) If any Bank shall have determined that, after the date of this
Agreement, the adoption of any applicable law, rule or regulation regarding
capital adequacy, or any change in any such law, rule or regulation, or any
change in the interpretation or administration thereof by any governmental
authority, central bank or comparable agency charged with the interpretation or
administration thereof, or any request or directive regarding capital adequacy
(whether or not having the force of law) of any such authority, central bank or
comparable agency (including any determination by any such authority, central
bank or comparable agency that, for purposes of capital adequacy requirements,
the Commitments hereunder do not constitute commitments with an original
maturity of one year or less), has or would have the effect of reducing the rate
of return on capital of such Bank (or its Parent) as a consequence of such
Bank's obligations hereunder to a level below that which such Bank (or its
Parent) could have achieved but for such adoption, change, request or directive
(taking into consideration its policies with respect to capital adequacy) by an
amount deemed by such Bank to be material, then from time to time, within 15
days after written demand by such Bank (with a copy to the Agent), the Borrower
shall pay to such Bank such additional amount or amounts as will compensate such
Bank (or its Parent) for such reduction.

          (c) Each Bank will promptly notify the Borrower and the Agent of any
event of which it has knowledge, occurring after the date of this Agreement,
which will entitle such Bank to compensation pursuant to this Section; provided
that (i) if any Bank fails to give such notice within 90 days after it obtains
actual knowledge of such an event, such Bank shall only be entitled to payment
under this Section 8.03 for costs incurred from and after the date 90 days prior
to the date that such Bank does give such notice and (ii) each such Bank will
designate a different Applicable Lending Office if such designation will avoid
the need for, or reduce the amount of, such compensation and will not, in the
judgment of such Bank in the good faith exercise of its discretion, be otherwise
disadvantageous to such Bank. A certificate of any Bank claiming compensation
under this Section and setting forth in reasonable detail the additional amount
or amounts to be paid to it hereunder and the basis used to determine such
amounts shall be conclusive in the absence of manifest error. In determining
such amount, such Bank will use


                                       56
<PAGE>   62
reasonable averaging and attribution methods and will have a reasonable basis
for any assumptions it makes in connection therewith.

         SECTION 8.04. Taxes. (a) Any and all payments by the Borrower to or for
the account of any Bank or the Agent hereunder or under any Promissory Note
shall be made free and clear of and without deduction for any and all present or
future taxes, duties, levies, imposts, deductions, charges or withholdings, and
all liabilities with respect thereto, excluding, in the case of each Bank and
the Agent, taxes imposed on or measured by its income, and franchise taxes
imposed on it, by the jurisdiction under the laws of which such Bank or the
Agent (as the case may be) is organized or any political subdivision thereof
and, in the case of each Bank, taxes imposed on or measured by its income, and
franchise or similar taxes imposed on it, by the jurisdiction of such Bank's
Applicable Lending Office or any political subdivision thereof (all such
non-excluded taxes, duties, levies, imposts, deductions, charges, withholdings
and liabilities being hereinafter referred to as its "TAXES", and all such
excluded taxes being hereinafter referred to as its "DOMESTIC TAXES"). If the
Borrower shall be required by law to deduct any Taxes from or in respect of any
sum payable hereunder or under any Promissory Note to any Bank or the Agent, (i)
the sum payable shall be increased as necessary so that after making all
required deductions (including deductions applicable to additional sums payable
under this Section 8.04 such Bank or the Agent (as the case may be) receives an
amount equal to the sum it would have received had no such deductions been made,
(ii) the Borrower shall make such deductions, (iii) the Borrower shall pay the
full amount deducted to the relevant taxation authority or other authority in
accordance with applicable law and (iv) the Borrower shall furnish to the Agent,
at its address referred to in Section 9.01, the original or a certified copy of
a receipt evidencing payment thereof.

          (b) In addition, the Borrower agrees to pay any present or future
stamp or documentary taxes and any other excise or property taxes, or charges or
similar levies which arise from any payment made hereunder or under any
Promissory Note or from the execution or delivery of, or otherwise with respect
to, this Agreement or any other Financing Document (hereinafter referred to as
"OTHER TAXES").

          (c) The Borrower agrees to indemnify each Bank and the Agent for the
full amount of Taxes or Other Taxes (including, without limitation, any Taxes or
Other Taxes imposed or asserted by any jurisdiction on amounts payable under
this Section 8.04 paid by such Bank or the Agent (as the case may be) and any
liability (including penalties, interest and expenses) arising therefrom or with
respect thereto. In addition, on and after the New Borrower Date, the Borrower
agrees to indemnify the Agent and each Bank for all Domestic Taxes and any
liability (including penalties, interest and expenses) arising therefrom or with
respect thereto, in each case to the extent that such Domestic Taxes result from
any payment or indemnification pursuant to this Section for (i) Taxes or Other
Taxes imposed by any jurisdiction other than the United States or (ii) Domestic
Taxes of the Agent or such Bank, as the case may be. This indemnification shall
be made within 15 days from the date such Bank or the Agent (as the case may be)
makes demand therefor.


                                       57
<PAGE>   63
          (d) At the times indicated herein, each Bank organized under the laws
of a jurisdiction outside the United States shall provide the Borrower with
Internal Revenue Service form 1001 or 4224 (in each case accompanied by any
statements which may be required under applicable Treasury regulations), as
appropriate, or any successor form prescribed by the Internal Revenue Service,
certifying that such Bank is entitled to receive payments under this Agreement
(i) without deduction or withholding of any United States federal income taxes
or (ii) subject to a reduced rate of United States federal withholding tax,
unless, in each case of clause (i) and (ii) of this Section 8.04(d), an event
(including, without limitation, any change in treaty, law or regulation) has
occurred prior to the date on which any such delivery would otherwise be
required which renders such forms inapplicable or which would prevent the Bank
from duly completing and delivering any such form with respect to it and the
Bank advises the Borrower and the Agent that it is not capable of receiving
payments without any deduction or withholding of such taxes. Such forms shall be
provided (x) on or prior to the date of the Bank's execution and delivery of
this Agreement in the case of each Bank listed on the signature pages hereof,
and on or prior to the date on which it becomes a Bank in the case of each other
Bank, and (y) on or before the date that such form expires or becomes obsolete
or after the occurrence of any event requiring a change in the most recent form
so delivered by the Bank. If the form provided by a Bank at the time such Bank
first becomes a party to this Agreement indicates a United States interest
withholding tax rate in excess of zero, United States withholding tax at such
rate shall be considered excluded from "TAXES" as defined in Section 8.04(a). In
addition, to the extent that for reasons other than a change of treaty, law or
regulation any Bank becomes subject to an increased rate of United States
interest withholding tax while it is a party to this Agreement, United States
withholding tax at such increased rate shall be considered excluded from "Taxes"
as defined in Section 8.04(a).

          (e) For any period with respect to which a Bank has failed to provide
the Borrower with the appropriate form in accordance with Section 8.04(d)
(unless such failure is excused by the terms of Section 8.04(d)), such Bank
shall not be entitled to indemnification under Section 8.04(a) or 8.04(c) with
respect to Taxes imposed by the United States; provided, however, that should a
Bank, which is otherwise exempt from or subject to a reduced rate of withholding
tax, become subject to Taxes because of its failure to deliver a form required
hereunder, the Borrower shall take such steps as such Bank shall reasonably
request to assist such Bank to recover such Taxes.

          (f) If the Borrower is required to pay additional amounts to or for
the account of any Bank pursuant to this Section 8.04, then such Bank will
change the jurisdiction of its Applicable Lending Office so as to eliminate or
reduce any such additional payment which may thereafter accrue if such change,
in the judgment of such Bank in the good faith exercise of its discretion, is
not otherwise disadvantageous to such Bank.

         SECTION 8.05. Base Rate Loans Substituted for Affected Fixed Rate
Loans. If (i) the obligation of any Bank to make, or to continue or convert
outstanding Loans as or to Euro-Dollar Loans has been suspended pursuant to
Section 8.02 or (ii) any Bank has demanded compensation under Section 8.03 or
8.04 with respect to its CD Loans or Euro-Dollar Loans and the Borrower


                                       58
<PAGE>   64
shall, by at least five Euro-Dollar Business Days' prior notice to such Bank
through the Agent, have elected that the provisions of this Section shall apply
to such Bank, then, unless and until such Bank notifies the Borrower that the
circumstances giving rise to such suspension or demand for compensation no
longer exist (which such Bank agrees to do promptly upon such circumstances
ceasing to exist), all Loans which would otherwise be made by such Bank as (or
continued as or converted to) CD Loans or Euro-Dollar Loans, as the case may be,
shall instead be Base Rate Loans (on which interest and principal shall be
payable contemporaneously with the related Fixed Rate Loans of the other Banks).
If such Bank notifies such Borrower that the circumstances giving rise to such
suspension or demand for compensation no longer exist, the principal amount of
each such Base Rate Loan shall be converted into a CD Loan or Euro-Dollar Loan,
as the case may be, on the first day of the next succeeding Interest Period
applicable to the related CD Loans or Euro-Dollar Loans of the other Banks.

         SECTION 8.06. Substitution of Bank. If any Bank (i) has demanded
compensation for increased costs pursuant to Section 8.03 or 8.04 or is entitled
to payments under Section 8.04(a) or (ii) has determined that the making or
maintaining of any Euro-Dollar Loan has become unlawful or impossible pursuant
to Section 8.02 and similar additional interest or compensation has not been
demanded by, or a similar determination has not been made by, all of the Banks,
the Borrower shall have the right (with the assistance of the Agent) to
designate an Assignee which is not an Affiliate of the Borrower to purchase for
cash, pursuant to an Assignment and Assumption Agreement in substantially the
form of Exhibit G hereto, the outstanding Loans and Commitment of such Bank and
to assume all of such Bank's other rights and obligations hereunder without
recourse to or warranty by, or expense to, such Bank, for a purchase price equal
to the principal amount of all of such Bank's outstanding Loans plus any accrued
but unpaid interest thereon and the accrued but unpaid fees in respect of that
Bank's Commitment hereunder plus such amount, if any, as would be payable
pursuant to Section 2.13 if the outstanding Loans of such Bank were prepaid in
their entirety on the date of consummation of such assignment.

                                  MISCELLANEOUS

         SECTION 9.01. Notices. All notices, requests and other communications
to any party provided for hereunder shall be in writing (including, without
limitation, bank wire, telex, facsimile transmission or similar writing) and

its address or facsimile or telex number set forth on the signature pages
hereof, (y) in the case of any Bank, at its address or facsimile or telex number
set forth in its Administrative Questionnaire or (z) in the case of any party,
such other address or facsimile or telex number as such party may hereafter
specify for the purpose by notice to the Agent and the Borrower. Each such
notice, request or other communication shall be effective (i) if given by telex,
when such telex is transmitted to the telex number specified in this Section and
the appropriate answerback is received, (ii) if given by facsimile, when such
facsimile is transmitted


                                       59
<PAGE>   65
to the facsimile number specified in this Section 9.01 and electronic,
telephonic or other appropriate confirmation of receipt is received by the
sender, (iii) if given by mail, 72 hours after such communication is deposited
in the mails with first class postage prepaid, addressed as aforesaid or (iv) if
given by any other means, when delivered at the address specified in this
Section; provided that notices to the Agent under Article 2 or Article 8 shall
not be effective until received.

         SECTION 9.02. No Waivers. No failure or delay by the Agent or any Bank
in exercising any right, power or privilege hereunder or under any other
Financing Document shall operate as a waiver thereof nor shall any single or
partial exercise thereof preclude any other or further exercise thereof or the
exercise of any other right, power or privilege. The rights and remedies herein
and therein provided shall be cumulative and not exclusive of any rights or
remedies provided by law.

         SECTION 9.03. Expenses; Indemnification. (a) The Borrower shall pay (i)
all reasonable out-of-pocket expenses of the Agent, including reasonable fees
and disbursements of special counsel for the Agent, in connection with the
preparation and administration of the Financing Documents, any waiver or consent
hereunder or any amendment thereof or any Default or alleged Default hereunder
and (ii) if an Event of Default occurs, all reasonable out-of-pocket expenses
incurred by the Agent and each Bank, including reasonable fees and disbursements
of counsel, in connection with such Event of Default and collection, bankruptcy,
insolvency and other enforcement proceedings resulting therefrom.

          (b) The Borrower agrees to indemnify the Agent and each Bank, their
respective Bank Affiliates and the respective directors, officers, agents and
employees of the foregoing (each an "Indemnitee") and hold each Indemnitee
harmless from and against any and all liabilities, losses, damages, costs and
expenses, including, without limitation, the reasonable fees and disbursements
of counsel, which may be incurred by such Indemnitee (whether or not such
Indemnitee shall be designated a party thereto) arising out of any
investigative, administrative or judicial proceeding (brought or threatened)
relating to or arising out of the Financing Documents, the arrangement,
administration, performance or enforcement thereof or any actual or proposed use
of proceeds of Loans hereunder; provided that no Indemnitee shall have the right
to be indemnified hereunder for such Indemnitee's own gross negligence or
willful misconduct as determined by a court of competent jurisdiction; provided
further that no Indemnitee shall have the right to be indemnified hereunder in
connection with any proceedings between it and another Indemnitee which does not
relate to the Borrower.

         (c) If any proceeding or claim shall be brought or asserted against any
Indemnitee in respect of which indemnity may be sought pursuant to the preceding
subsection, such Indemnitee shall promptly notify the Borrower. The Borrower
shall not be liable for any costs or expenses in connection with any settlement
entered into without its consent.

         SECTION 9.04. Sharing of Set-Offs. Each Bank agrees that if it shall,
by exercising any right of set-off or counterclaim or otherwise, receive payment
of a proportion of the aggregate


                                       60
<PAGE>   66
amount of principal and interest due with respect to any Promissory Note held by
it which is greater than the proportion received by any other Bank in respect of
the aggregate amount of principal and interest due with respect to any
Promissory Note held by such other Bank, the Bank receiving such proportionately
greater payment shall purchase such participations in the Promissory Notes held
by the other Banks, and such other adjustments shall be made, as may be
required, so that all such payments of principal and interest with respect to
the Promissory Notes held by the Banks shall be shared by the Banks pro rata;
provided that nothing in this Section shall impair the right of any Bank to
exercise any right of set-off or counterclaim it may have and to apply the
amount subject to such exercise to the payment of indebtedness of the Borrower
other than its indebtedness under the Promissory Notes.

         SECTION 9.05. Amendments and Waivers. Any provision of this Agreement
or the Promissory Notes may be amended or waived if, but only if, such amendment
or waiver is in writing and is signed by the Borrower and the Required Banks
(and, if the rights or duties of the Agent are affected thereby, by the Agent);
provided that no such amendment or waiver shall, unless signed by all the Banks,
(i) increase or decrease the Commitment of any Bank (except for a ratable
decrease in the Commitments of all Banks) or subject any Bank to any additional
obligation, (ii) reduce the principal of or rate of interest on any Loan or any
fees hereunder, (iii) postpone the date fixed for any payment of principal of or
interest on any Loan or any fees hereunder or for termination of any Commitment,
(iv) change the percentage of the Commitments or of the aggregate unpaid
principal amount of the Promissory Notes, or the number of Banks, which shall be
required for the Banks or any of them to take any action under this Section or
any other provision of this Agreement or (v) release the Parent Guarantor from
its obligations under the Parent Guarantee.

         SECTION 9.06. Successors and Assigns. (a) The provisions of this
Agreement shall be binding upon and inure to the benefit of the parties hereto
and their respective successors and assigns, except that the Borrower may not
assign or otherwise transfer any of its rights under this Agreement without the
prior written consent of all Banks.

         (b) Any Bank may at any time grant to one or more banks or other
institutions (each a "Participant") participating interests in its Commitment or
any or all of its Loans. In the event of any such grant by a Bank of a
participating interest to a Participant, whether or not upon notice to the
Borrower and the Agent, such Bank shall remain responsible for the performance
of its obligations hereunder, and the Borrower and the Agent shall continue to
deal solely and directly with such Bank in connection with such Bank's rights
and obligations under this Agreement. Any agreement pursuant to which any Bank
may grant such a participating interest shall provide that such Bank shall
retain the sole right and responsibility to enforce the obligations of the
Borrower hereunder including, without limitation, the right to approve any
amendment, modification or waiver of any provision of this Agreement; provided
that such participation agreement may provide that such Bank will not agree to
any modification, amendment or waiver of this Agreement described in clause (i),
(ii), (iii) or (iv) of Section 9.05 without the consent of the Participant. The
Borrower agrees that each Participant shall, to the extent provided in its
participation agreement and subject to subsection (e), (f) and (g) below, be
entitled to the benefits


                                       61
<PAGE>   67
of Article 8 with respect to its participating interest. An assignment or other
transfer which is not permitted by subsection 9.06(c) or 9.06(d) below shall be
given effect for purposes of this Agreement only to the extent of a
participating interest granted in accordance with this subsection (b).

         (c) Any Bank may at any time assign to one or more banks or other
institutions (each an "Assignee") all, or a proportionate part (in an amount
equivalent to an original Commitment of not less than $10,000,000) of all, of
its rights and obligations under this Agreement and the Promissory Notes, and
such Assignee shall assume such rights and obligations, pursuant to an
Assignment and Assumption Agreement in substantially the form of Exhibit G
hereto executed by such Assignee and such transferor Bank, with (and subject to)
the subscribed consent of the Borrower and the Agent, which shall not be
unreasonably withheld; provided that if an Assignee is an affiliate of such
transferor Bank, no such consent shall be required; and provided further that
such assignment may, but need not, include rights of the transferor Bank in
respect of outstanding Money Market Loans. Upon execution and delivery of such
instrument and payment by such Assignee to such transferor Bank of an amount
equal to the purchase price agreed between such transferor Bank and such
Assignee, such Assignee shall be a Bank party to this Agreement and shall have
all the rights and obligations of a Bank with a Commitment as set forth in such
instrument of assumption, and the transferor Bank shall be released from its
obligations hereunder to a corresponding extent, and no further consent or
action by any party shall be required. Upon the consummation of any assignment
pursuant to this subsection (c), the transferor Bank, the Agent and the Borrower
shall make appropriate arrangements so that, if required, a new Promissory Note
is issued to the Assignee. In connection with any such assignment, the
transferor Bank shall pay to the Agent an administrative fee for processing such
assignment in the amount of $2,500. If the Assignee is not incorporated under
the laws of the United States of America or a state thereof, it shall deliver to
the Borrower and the Agent certification as to exemption from deduction or
withholding of any United States federal income taxes in accordance with Section
8.04.

         (d) Any Bank may at any time assign all or any portion of its rights
under this Agreement and its Promissory Note to a Federal Reserve Bank. No such
assignment shall release the transferor Bank from its obligations hereunder.

         (e) No Assignee, Participant or other transferee of any Bank's rights
shall be entitled to receive any greater payment under Section 8.03 or 8.04 than
such Bank would have been entitled to receive with respect to the rights
transferred, unless such transfer is made with the Borrower's prior written
consent or by reason of the provisions of Section 8.02, 8.03 or 8.04 requiring
such Bank to designate a different Applicable Lending Office under certain
circumstances or at a time when the circumstances giving rise to such greater
payment did not exist.

         (f) Notwithstanding anything to the contrary contained in this Section
9.06 but subject to the terms and conditions set forth in this subsection (f),
any Bank may from time to time, elect to designate a Conduit to provide all or
any part of Loans required to be made by such Bank to the Borrower pursuant to
this Agreement or to acquire a participation interest in any Loans


                                       62
<PAGE>   68
extended by such Bank hereunder (a "CONDUIT DESIGNATION"), provided the
designation of a Conduit by any Bank for purposes of this Section 9.06(f) shall
be subject to the approval of the Borrower. No additional Note shall be required
with regard to a Conduit Designation; provided, however, to the extent any
Conduit shall advance funds under a Conduit Designation, the designating Bank
shall be deemed to hold the Note in its possession as an agent for such Conduit
to the extent of the Loan funded by such Conduit. Notwithstanding any such
Conduit Designation, (x) the designating Bank shall remain solely responsible to
the other parties hereto for its obligations under this Agreement and (y) the
Borrower and the Agent may continue to deal solely and directly with the
designating Bank as administrative agent for such designating Bank's Conduit, in
connection with all of such Conduit's rights and obligations under this
Agreement, unless and until the Borrower and the Agent are notified that the
designating Bank has been replaced as administrative agent for its Conduit; any
payments for the benefit of any designating Bank and its Conduit shall be paid
to such designating Bank for itself as administrative agent for its Conduit, as
applicable; provided neither the Borrower nor the Agent shall be responsible for
any designating Bank's application of any such payments. In addition, any
Conduit may (i) with notice to, but without the prior written consent of the
Borrower and the Agent, and without paying any processing fee therefor, assign
all or portions of its interest in any Loans to the Bank that designated such
Conduit or to any financial institutions consented to by the Borrower and the
Agent providing liquidity and/or credit facilities to or for the account of such
Conduit to support the funding or maintenance of Loans and (ii) disclose on a
confidential basis any non-public information relating to its Loans to any
rating agency, commercial paper dealer or provider of any guarantee, surety,
credit or liquidity enhancement to such Conduit.

         (g) Each party to this Agreement hereby agrees that, at any time a
Conduit Designation is in effect, it shall not institute against, or join any
other person in instituting against, any Conduit any bankruptcy, reorganization,
arrangement, insolvency or liquidation proceeding or other proceedings under any
federal or state bankruptcy or similar law, for one year and a day after the
latest maturing commercial paper note issued by such Conduit is paid. This
Section 9.06(g) shall survive the termination of this Agreement.

         SECTION 9.07. Collateral. Each of the Banks represents to the Agent and
each of the other Banks that it in good faith is not relying upon any "margin
stock" (as defined in Regulation U) as collateral in the extension or
maintenance of the credit provided for in this Agreement.

         SECTION 9.08. Governing Law; Submission to Jurisdiction. THIS AGREEMENT
AND EACH PROMISSORY NOTE SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH
THE LAWS OF THE STATE OF NEW YORK. THE BORROWER HEREBY SUBMITS TO THE
NONEXCLUSIVE JURISDICTION OF THE UNITED STATES DISTRICT COURT FOR THE SOUTHERN
DISTRICT OF NEW YORK AND OF ANY NEW YORK STATE COURT SITTING IN NEW YORK CITY
FOR PURPOSES OF ALL LEGAL PROCEEDINGS ARISING OUT OF OR RELATING TO THIS
AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY. THE BORROWER IRREVOCABLY
WAIVES, TO THE FULLEST EXTENT PERMITTED BY LAW, ANY OBJECTION WHICH


                                       63
<PAGE>   69
IT MAY NOW OR HEREAFTER HAVE TO THE LAYING OF THE VENUE OF ANY SUCH PROCEEDING
BROUGHT IN SUCH A COURT AND ANY CLAIM THAT ANY SUCH PROCEEDING BROUGHT IN SUCH A
COURT HAS BEEN BROUGHT IN AN INCONVENIENT FORUM.

         SECTION 9.09. Counterparts; Integration. This Agreement may be signed
in any number of counterparts, each of which shall be an original, with the same
effect as if the signatures thereto and hereto were upon the same instrument.
This Agreement constitutes the entire agreement and understanding among the
parties hereto and supersedes any and all prior agreements and understandings,
oral or written, relating to the subject matter hereof.

         SECTION 9.10. Waiver of Jury Trial. EACH OF THE BORROWER, THE AGENT AND
THE BANKS HEREBY IRREVOCABLY WAIVES ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY
LEGAL PROCEEDING ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE
TRANSACTIONS CONTEMPLATED HEREBY.

         SECTION 9.11. Judgment Currency. If, under any applicable law and
whether pursuant to a judgment being made or registered against the Borrower or
for any other reason, any payment under or in connection with this Agreement, is
made or satisfied in a currency (the "Other Currency") other than that in which
the relevant payment is due (the "Required Currency") then, to the extent that
the payment (when converted into the Required Currency at the rate of exchange
on the date of payment or, if it is not practicable for the party entitled
thereto (the "Payee") to purchase the Required Currency with the other Currency
on the date of payment, at the rate of exchange as soon thereafter as it is
practicable for it to do so) actually received by the Payee falls short of the
amount due under the terms of this Agreement, the Borrower shall, to the extent
permitted by law, as a separate and independent obligation, indemnify and hold
harmless the Payee against the amount of such short-fall. For the purpose of
this Section, "rate of exchange" means the rate at which the Payee is able on
the relevant date to purchase the Required Currency with the Other Currency and
shall take into account any premium and other costs of exchange.
<PAGE>   70
         IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be
duly executed by their respective authorized officers as of the day and year
first above written.

                       Form of Opinion of General Counsel
                                 of the Borrower


                                [Effective Date]


To the Banks and the Agent
Named on the Attached Distribution List
c/o Morgan Guaranty Trust Company
of New York, As Agent
60 Wall Street
New York, New York 10260
Ladies and Gentlemen:


         I am the General Counsel of Tyco International (US) Inc., a
Massachusetts corporation (the "Borrower") and am rendering this opinion in
connection with that certain 364-Day Credit Agreement and that certain
Extendible 364-Day Credit Agreement (collectively, the "Credit Agreements"),
each dated as of February 13, 1998, among the Borrower, the banks listed on the
signature pages thereof (the "Banks") and Morgan Guaranty Trust Company of New
York, as Agent. This opinion is being delivered to you pursuant to Section
3.01(e) of each Credit Agreement. Each term defined in the Credit Agreements and
used herein, but not otherwise defined herein, has the meaning ascribed thereto
in the Credit Agreements.

         In connection with the opinion set forth herein, I have reviewed the
Credit Agreements, the Promissory Notes of the Borrower and the Parent Guarantee
and have examined originals or copies, certified or otherwise identified to my
satisfaction, of (i) the Restated Articles of Organization and By-laws of the
Borrower, each as in effect on the date hereof and (ii) such other documents,
records, certificates and instruments as I have deemed relevant and necessary as
a basis for the opinion hereinafter expressed.

         In my examination, I have assumed the genuineness of all signatures on
original documents, the authenticity of all documents submitted to me as
originals, the conformity to the originals of all copies submitted to me as
certified, conformed or photostatic copies, and the authenticity of the
originals of such copies. As to various questions of fact material to this
opinion, I have relied, without independent investigation or verification, upon
statements, representations and certificates of officers and other
representatives of the Borrower and certificates of public officials. In
addition, I have assumed that (i) the Credit Agreements have been validly
authorized, executed and delivered by all parties thereto (other than the
Borrower), (ii) each party to the Credit Agreements (other than the Borrower)
has been duly organized and is a corporation or other entity validly existing
and in good standing (to the extent applicable) under the laws of its respective
jurisdiction of organization, with the full corporate or other
<PAGE>   87
organizational power to execute and deliver the Credit Agreements and to perform
its respective obligations thereunder, (iii) the Credit Agreements constitute
the legal, valid and binding obligations of the respective parties thereto
(other than the Borrower) enforceable against such parties in accordance with
their respective terms, (iv) the execution and delivery of the Credit Agreements
by each party thereto (other than the Borrower) and the performance by such
parties of their respective obligations thereunder do not violate such parties'
respective articles or certificate of incorporation or by-laws, or other
organizational documents, and (v) the execution, delivery and performance by
each party to the Credit Agreements (other than the Borrower) and the
performance by such parties of their respective obligations thereunder do not
violate any agreement, judgment, injunction, decree, order of any governmental
authority, other instrument, law or regulation applicable to such party.

         Based upon the foregoing, and subject to the qualifications and
assumptions set forth herein, it is my opinion that:

         1. The Borrower is a corporation duly incorporated, validly existing
and in good standing under the laws of the Commonwealth of Massachusetts, and
has all corporate powers and all material governmental licenses, authorizations,
consents and approvals (collectively, the "Consents") required to carry on its
business as now conducted, other than those powers and Consents, the failure of
which to be possessed or obtained could not, based upon the facts and
circumstances in existence on the date hereof, reasonably be expected to have a
Material Adverse Effect.

         2. The execution, delivery and performance by the Borrower of the
Credit Agreements and the Promissory Notes (a) are within the Borrower's
corporate powers; (b) have been duly authorized by all necessary corporate
action on the part of the Borrower; (c) require no action by or in respect of,
or filing with, any governmental body, agency or official, in each case, on the
part of the Borrower; and (d) do not contravene, or constitute a default by the
Borrower under, any provision of (i) applicable law or regulation, (ii) the
certificate of incorporation or by-laws of the Borrower or, (iii) any agreement
or instrument evidencing or governing Debt of the Borrower, or any other
agreement, judgment, injunction, order, decree or other instrument binding upon
the Borrower.

         3. Each Credit Agreement constitutes a valid and binding agreement of
the Borrower and each Promissory Note constitutes a valid and binding obligation
of the Borrower.

         4. There is no action, suit or proceeding pending against, or, to the
best of my knowledge, threatened against or affecting, the Borrower or any of
its Subsidiaries before any court or arbitrator or any governmental body, agency
or official, in which there is a reasonable possibility of an adverse decision
which could, based upon the facts and circumstances in existence on the date
hereof, reasonably be expected to have a Material Adverse Effect or which in any
manner draws into question the validity of the Financing Documents.

                                        2
<PAGE>   88
         5. Each of the Borrower's corporate Subsidiaries is a corporation
validly existing and in good standing under the laws of its jurisdiction of
incorporation, except where the failure to be so incorporated, existing or in
good standing could not, based upon the facts and circumstances existing on the
date hereof, reasonably be expected to have a Material Adverse Effect, and has
all corporate powers and all Consents required to carry on its business as now
conducted other than those powers and Consents, the failure of which to be
possessed or obtained could not, based upon the facts and circumstances in
existence on the date hereof, reasonably be expected to have a Material Adverse
Effect.

         The opinion set forth herein is subject to the following qualifications
and limitations:

         (a) The enforceability of the Credit Agreements and the Promissory
Notes may be subject to or limited by bankruptcy, insolvency, reorganization,
arrangement, moratorium, fraudulent conveyance or transfer or other similar laws
and court decisions, now or hereafter in effect, relating to or affecting the
rights of creditors generally.

         (b) The enforceability of the Credit Agreements and the Promissory
Notes is or will be subject to the application of and may be limited by general
principles of equity including, without limitation, concepts of materiality,
reasonableness, good faith and fair dealing (regardless of whether considered in
a proceeding in equity or at law). Such principles of equity are of general
application, and in applying such principles a court, among other things, might
not allow a creditor to accelerate maturity of a debt under certain
circumstances including, without limitation, upon the occurrence of a default
deemed immaterial, or might decline to order the Borrower or any of the other
parties to the Financing Documents to perform covenants. Such principles as
applied by a court might include a requirement that a creditor act with
reasonableness and in good faith. Thus, I express no opinion as to the validity
or enforceability of (i) provisions restricting access to legal or equitable
remedies, such as the specific performance of executory covenants, (ii)
provisions that purport to establish evidentiary standards, (iii) provisions
relating to waivers, severability, set-off, or delay or omission of enforcement
of rights or remedies, and (iv) provisions purporting to convey rights to
persons other than parties to the Financing Documents.

         (c) The remedy of specific performance and injunctive and other forms
of equitable relief are subject to equitable defenses and to the discretion of
the court before which any proceeding therefor may be brought.

         (d) I have not been requested to render, and with your permission I do
not express, any opinion as to the applicability to any provision of the
Financing Documents, of Section 548 of the Federal Bankruptcy Code, Article 10
of the New York Debtor & Creditor Law, or any other fraudulent conveyance,
insolvency or transfer laws or any court decisions with respect to any of the
foregoing.

                                        3
<PAGE>   89
         I call your attention to the fact that I am admitted to practice law
only in the State of New York and the Commonwealth of Massachusetts, and, in
rendering the foregoing opinion, I do not express any opinion as to any laws
other than the laws of the State of New York, the Commonwealth of Massachusetts
and the Federal laws of the United States of America.

         The opinion expressed herein is based upon the laws in effect on the
date hereof, and I assume no obligation to revise or supplement this opinion
should any such law be changed by legislative action, judicial decision, or
otherwise.

         This opinion is being delivered to you solely for your benefit in
connection with the Financing Documents, and neither this opinion nor any part
hereof may be delivered to, or used, referred to or relied upon, by any other
person or for any other purpose without my express prior written consent, except
that any person who is a permitted successor or assign of a Bank in accordance
with the provisions of the Credit Agreement may rely upon this opinion as if it
were specifically addressed and delivered to such person on the date hereof.

                                            Very truly yours,

                       Form of Opinion of General Counsel
                of the Borrower on Behalf of the Parent Guarantor


                                [Effective Date]


To the Banks and the Agent
Named on the Attached Distribution List
c/o Morgan Guaranty Trust Company
of New York, As Agent
60 Wall Street
New York, New York 10260
Ladies and Gentlemen:


         I am the General Counsel of Tyco International (US) Inc., a
Massachusetts corporation and a wholly owned indirect subsidiary of Tyco
International Ltd., a Bermuda corporation (the "Parent Guarantor") and am
rendering this opinion in connection with that certain Parent Guarantee (the
"Parent Guarantee"), dated as of February 13, 1998, entered into by the Parent
Guarantor pursuant to that certain 364-Day Credit Agreement and that certain
Extendible 364- Day Credit Agreement (collectively, the "Credit Agreements"),
each dated as of February 13, 1998, among Tyco International (US) Inc. (the
"Borrower"), the banks listed on the signature pages thereof (the "Banks") and
Morgan Guaranty Trust Company of New York, as Agent. This opinion is being
delivered to you pursuant to Section 3.01(e) of each Credit Agreement. Each term
defined in the Credit Agreements and used herein, but not otherwise defined
herein, has the meaning ascribed thereto in the Credit Agreements.

         In connection with the opinion set forth herein, I have reviewed the
Credit Agreements, the Promissory Notes of the Borrower and the Parent Guarantee
and have examined originals or copies, certified or otherwise identified to my
satisfaction, of (i) the [Memorandum of Association and By-laws] of the Parent
Guarantor, each as in effect on the date hereof and (ii) such other documents,
records, certificates and instruments as I have deemed relevant and necessary as
a basis for the opinion hereinafter expressed.

         In my examination, I have assumed the genuineness of all signatures on
original documents, the authenticity of all documents submitted to me as
originals, the conformity to the originals of all copies submitted to me as
certified, conformed or photostatic copies, and the authenticity of the
originals of such copies. As to various questions of fact material to this
opinion, I have relied, without independent investigation or verification, upon
statements, representations and certificates of officers and other
representatives of the Parent Guarantor and certificates of public officials.
<PAGE>   91
         Based upon the foregoing, and subject to the qualifications and
assumptions set forth herein, it is my opinion that:

         1. The execution, delivery and performance by the Parent Guarantor of
the Parent Guarantee (a) require no action by or in respect of, or filing with,
any governmental body, agency or official, in each case, on the part of the
Parent Guarantor; and (b) do not contravene, or constitute a default by the
Parent Guarantor under, any provision of (i) applicable law or regulation or
(ii) any agreement or instrument evidencing or governing Debt of the Parent
Guarantor, or any other agreement, judgment, injunction, order, decree or other
instrument binding upon the Parent Guarantor.

         2. The Parent Guarantee constitutes a valid and binding obligation of
the Parent Guarantor.

         3. There is no action, suit or proceeding pending against, or, to the
best of my knowledge, threatened against or affecting, the Parent Guarantor or
any of its Subsidiaries before any court or arbitrator or any governmental body,
agency or official, in which there is a reasonable possibility of an adverse
decision which could, based upon the facts and circumstances in existence on the
date hereof, reasonably be expected to have a Material Adverse Effect or which
in any manner draws into question the validity of the Financing Documents.

         4. Each of the Parent Guarantor's corporate Subsidiaries is a
corporation validly existing and in good standing under the laws of its
jurisdiction of incorporation, except where the failure to be so incorporated,
existing or in good standing could not, based upon the facts and circumstances
existing on the date hereof, reasonably be expected to have a Material Adverse
Effect, and has all corporate powers and all Consents required to carry on its
business as now conducted other than those powers and Consents, the failure of
which to be possessed or obtained could not, based upon the facts and
circumstances in existence on the date hereof, reasonably be expected to have a
Material Adverse Effect.

         The opinion set forth herein is subject to the following qualifications
and limitations:

         (a) The enforceability of the Parent Guarantee may be subject to or
limited by bankruptcy, insolvency, reorganization, arrangement, moratorium,
fraudulent conveyance or transfer or other similar laws and court decisions, now
or hereafter in effect, relating to or affecting the rights of creditors
generally.

         (b) The enforceability of the Parent Guarantee is or will be subject to
the application of and may be limited by general principles of equity including,
without limitation, concepts of materiality, reasonableness, good faith and fair
dealing (regardless of whether considered in a proceeding in equity or at law).
Such principles of equity are of general application, and in applying such
principles a court, among other things, might not allow a creditor to accelerate
maturity of a debt under certain circumstances including, without limitation,
upon the occurrence

                                        2
<PAGE>   92
of a default deemed immaterial, or might decline to order the Parent Guarantor
or any of the other parties to the Financing Documents to perform covenants.
Such principles as applied by a court might include a requirement that a
creditor act with reasonableness and in good faith. Thus, I express no opinion
as to the validity or enforceability of (i) provisions restricting access to
legal or equitable remedies, such as the specific performance of executory
covenants, (ii) provisions that purport to establish evidentiary standards,
(iii) provisions relating to waivers, severability, set-off, or delay or
omission of enforcement of rights or remedies, and (iv) provisions purporting to
convey rights to persons other than parties to the Financing Documents.

         (c) The remedy of specific performance and injunctive and other forms
of equitable relief are subject to equitable defenses and to the discretion of
the court before which any proceeding therefor may be brought.

         (d) I have not been requested to render, and with your permission I do
not express, any opinion as to the applicability to any provision of the
Financing Documents, of Section 548 of the Federal Bankruptcy Code, Article 10
of the New York Debtor & Creditor Law, or any other fraudulent conveyance,
insolvency or transfer laws or any court decisions with respect to any of the
foregoing.

         I call your attention to the fact that I am admitted to practice law
only in the State of New York and the Commonwealth of Massachusetts, and, in
rendering the foregoing opinion, I do not express any opinion as to any laws
other than the laws of the State of New York, the Commonwealth of Massachusetts
and the Federal laws of the United States of America. Insofar as the foregoing
opinion involves matters governed by the laws of Bermuda, I have relied, without
independent investigation, upon the opinion of ____________, a copy of which has
been delivered to you.

         The opinion expressed herein is based upon the laws in effect on the
date hereof, and I assume no obligation to revise or supplement this opinion
should any such law be changed by legislative action, judicial decision, or
otherwise.

         This opinion is being delivered to you solely for your benefit in
connection with the Financing Documents, and neither this opinion nor any part
hereof may be delivered to, or used, referred to or relied upon, by any other
person or for any other purpose without my express prior written consent, except
that any person who is a permitted successor or assign of a Bank in accordance
with the provisions of the Credit Agreement may rely upon this opinion as if it
were specifically addressed and delivered to such person on the date hereof.

                                                     Very truly yours,

                                   OPINION OF
                     DAVIS POLK & WARDWELL, SPECIAL COUNSEL
                                  FOR THE AGENT



To the Banks and the Agent
Referred to Below
c/o Morgan Guaranty Trust Company
of New York, as Agent
60 Wall Street
New York, New York 10260

Dear Sirs:


         We have participated in the preparation of the 364-Day Credit Agreement
and the Extendible 364-Day Credit Agreement (collectively, the "Credit
Agreements"), each dated as of February 13, 1998, among Tyco International (US)
Inc., a Massachusetts corporation (the "Borrower"), the banks listed on the
signature pages thereof (the "Banks") and Morgan Guaranty Trust Company of New
York, as Agent (the "Agent"), and have acted as special counsel for the Agent
for the purpose of rendering this opinion pursuant to Section 3.01(f) of the
Credit Agreements. Terms defined in the Credit Agreements are used herein as
therein defined.

         We have examined originals or copies, certified or otherwise identified
to our satisfaction, of such documents, corporate records, certificates of
public officials and other instruments and have conducted such other
investigations of fact and law as we have deemed necessary or advisable for
purposes of this opinion.

         Upon the basis of the foregoing, we are of the opinion that each Credit
Agreement constitutes a valid and binding agreement of the Borrower, that each
Promissory Note delivered on the date hereof constitutes a valid and binding
obligation of the Borrower and that the Parent Guarantee constitutes a valid and
binding obligation of the Parent Guarantor, in each case enforceable in
accordance with its terms, except as the same may be limited by bankruptcy,
insolvency or similar laws affecting creditors' rights generally and by general
principles of equity.

         We are members of the Bar of the State of New York and the foregoing
opinion is limited to the laws of the State of New York and the federal laws of
the United States of America. In giving the foregoing opinion, (i) we express no
opinion as to the effect (if any) of any law of any jurisdiction (except the
State of New York) in which any Bank is located which limits the rate of
<PAGE>   94
interest that such Bank may charge or collect and (ii) insofar as the foregoing
opinion involves matters governed by the laws of Massachusetts or Bermuda, we
have relied, without independent investigation, upon the respective opinions of
the General Counsel of the Borrower [and the Parent Guarantor] and of Appleby,
Spurling & Kempe, special Bermuda counsel for the Parent Guarantor, copies of
which have been delivered to you.

         This opinion is rendered solely to you in connection with the above
matter. This opinion may not be relied upon by you for any other purpose or
relied upon by any other person without our prior written consent, except that
any person who is a permitted successor or assign of a Bank in accordance with
the provisions of the Credit Agreement may rely upon this opinion as if it were
specifically addressed and delivered to such person on the date hereof.

                                Very truly yours,

                                        2

                       ASSIGNMENT AND ASSUMPTION AGREEMENT



         AGREEMENT dated as of _________, ____ among [ASSIGNOR] (the
"Assignor"), [ASSIGNEE] (the "Assignee"), [NAME OF BORROWER] (the "Borrower")
and MORGAN GUARANTY TRUST COMPANY OF NEW YORK, as Agent (the "Agent").



                               W I T N E S S E T H

         WHEREAS, this Assignment and Assumption Agreement (the "Agreement")
relates to the 364-Day Credit Agreement dated as of February 13, 1998 among the
Borrower, the Assignor and the other Banks party thereto, as Banks, and the
Agent (the "Credit Agreement");

         WHEREAS, as provided under the Credit Agreement, the Assignor has a
Commitment to make Loans to the Borrower in an aggregate principal amount at any
time outstanding not to exceed $__________;

         WHEREAS, Committed Loans made to the Borrower by the Assignor under the
Credit Agreement in the aggregate principal amount of $__________ are
outstanding at the date hereof; and

         WHEREAS, the Assignor proposes to assign to the Assignee all of the
rights of the Assignor under the Credit Agreement in respect of a portion of its
Commitment thereunder in an amount equal to $__________ (the "Assigned Amount"),
together with a corresponding portion of its outstanding Committed Loans, and
the Assignee proposes to accept assignment of such rights and assume the
corresponding obligations from the Assignor on such terms;

         NOW, THEREFORE, in consideration of the foregoing and the mutual
agreements contained herein, the parties hereto agree as follows:

         SECTION 1. Definitions. All capitalized terms not otherwise defined
herein shall have the respective meanings set forth in the Credit Agreement.

         SECTION 2. Assignment. The Assignor hereby assigns and sells to the
Assignee all of the rights of the Assignor under the Credit Agreement to the
extent of the Assigned Amount, and the Assignee hereby accepts such assignment
from the Assignor and assumes all of the obligations of
<PAGE>   96
the Assignor under the Credit Agreement to the extent of the Assigned Amount,
including the purchase from the Assignor of the corresponding portion of the
principal amount of the Committed Loans made by the Assignor outstanding at the
date hereof. Upon the execution and delivery hereof by the Assignor, the
Assignee, [the Borrower and the Agent] and the payment of the amounts specified
in Section 3 required to be paid on the date hereof (i) the Assignee shall, as
of the date hereof, succeed to the rights and be obligated to perform the
obligations of a Bank under the Credit Agreement with a Commitment in an amount
equal to the Assigned Amount, and (ii) the Commitment of the Assignor shall, as
of the date hereof, be reduced by a like amount and the Assignor released from
its obligations under the Credit Agreement to the extent such obligations have
been assumed by the Assignee. The assignment provided for herein shall be
without recourse to the Assignor.

         SECTION 3. Payments. As consideration for the assignment and sale
contemplated in Section 2 hereof, the Assignee shall pay to the Assignor on the
date hereof in Federal funds the amount heretofore agreed between them.* It is
understood that facility fees in respect of the Assigned Amount accrued to the
date hereof are for the account of the Assignor and such fees accruing from and
including the date hereof are for the account of the Assignee. Each of the
Assignor and the Assignee hereby agrees that if it receives any amount under the
Credit Agreement which is for the account of the other party hereto, it shall
receive the same for the account of such other party to the extent of such other
party's interest therein and shall promptly pay the same to such other party.

         [SECTION 4. Consent of the Borrower and the Agent. This Agreement is
conditioned upon the consent of the Borrower and the Agent pursuant to Section
9.06(c) of the Credit Agreement. The execution of this Agreement by the Borrower
and the Agent is evidence of this consent. Pursuant to Section 9.06(c) the
Borrower agrees to execute and deliver a Note payable to the order of the
Assignee to evidence the assignment and assumption provided for herein.]

         SECTION 5. Non-Reliance on Assignor. The Assignor makes no
representation or warranty in connection with, and shall have no responsibility
with respect to, the solvency, financial condition, or statements of the
Borrower, or the validity and enforceability of the obligations of the Borrower
in respect of the Credit Agreement or any Note. The Assignee acknowledges that
it has, independently and without reliance on the Assignor, and based on such
documents and information as it has deemed appropriate, made its own credit
analysis and decision to enter into this Agreement and will continue to be
responsible for making its own independent appraisal of the business, affairs
and financial condition of the Borrower.

- --------
              *Amount should combine principal together with accrued interest
and breakage compensation, if any, to be paid by the Assignee, net of any
portion of any upfront fee to be paid by the Assignor to the Assignee. It may be
preferable in an appropriate case to specify these amounts generically or by
formula rather than as a fixed sum.

                                       2
<PAGE>   97
         SECTION 6. Governing Law. This Agreement shall be governed by and
construed in accordance with the laws of the State of New York.

         SECTION 7. Counterparts. This Agreement may be signed in any number of
counterparts, each of which shall be an original, with the same effect as if the
signatures thereto and hereto were upon the same instrument.

         IN WITNESS WHEREOF, the parties have caused this Agreement to be
executed and delivered by their duly authorized officers as of the date first
above written.

                              SUBSIDIARY GUARANTEE

                            Dated as of ____________


         WHEREAS, [Name of Borrower], a ___________ corporation, has entered
into a 364-Day Credit Agreement and an Extendible 364-Day Credit Agreement
(collectively, as the same may be amended from time to time, the "Credit
Agreements") each dated as of February 13, 1998 among the Borrower, the banks
listed on the signature pages thereof, and Morgan Guaranty Trust Company of New
York, as Agent, pursuant to which the Borrower is entitled, subject to certain
conditions, to borrow up to $2,250,000,000;

         WHEREAS, in conjunction with the transactions contemplated by the
Credit Agreements and in consideration of the financial and other support that
the Borrower has provided, and such financial and other support as the Borrower
may in the future provide, to the undersigned (together with its successors, the
"Guarantor") and in order to induce the Banks and the Agent to enter into the
Credit Agreements and to make Loans thereunder, the Guarantor is willing to
guarantee the obligations of the Borrower under the Credit Agreements and the
Promissory Notes issued thereunder;

         NOW, THEREFORE, in consideration of the premises and other good and
valuable consideration, the receipt and sufficiency of which are hereby
acknowledged, the Guarantor hereby agrees as follows:



                                     ARTICLE


                                   DEFINITIONS

         SECTION 1. Definitions. Terms defined in the Credit Agreements and not
otherwise defined herein are used herein as therein defined (e.g., a "Loan" is a
Loan made pursuant to either Credit Agreement and a "Promissory Note" is a
Promissory Note issued pursuant to either Credit Agreement). In addition the
following terms, as used herein, have the following meanings:

         "Guaranteed Obligations" means (i) all obligations of the Borrower in
respect of principal of and interest on the Loans and the Promissory Notes, (ii)
all other amounts payable by the Borrower under either Credit Agreement or any
Promissory Note and (iii) all renewals or extensions of the foregoing, in each
case whether now outstanding or hereafter arising. The Guaranteed Obligations
shall include, without limitation, any interest, costs, fees and expenses which
accrue on or with respect to any of the foregoing and are payable by the
Borrower pursuant to either Credit Agreement or any Promissory Note, whether
before or after the
<PAGE>   99
commencement of any case, proceeding or other action relating to the bankruptcy,
insolvency or reorganization of any one or more than one of the Obligors, and
any such interest, costs, fees and expenses that would have accrued thereon or
with respect thereto and would have been payable by the Borrower pursuant to
such Credit Agreement or Promissory Note but for the commencement of such case,
proceeding or other action.


                                     ARTICLE

                                    GUARANTEE

         SECTION 1. The Guarantees. Subject to Section 3, the Guarantor hereby
unconditionally and irrevocably guarantees to the Banks and the Agent and to
each of them, the due and punctual payment of all Guaranteed Obligations as and
when the same shall become due and payable, whether at maturity, by declaration
or otherwise, according to the terms thereof. In case of failure by the Borrower
punctually to pay the indebtedness guaranteed hereby, the Guarantor, subject to
Section 3, hereby unconditionally agrees to cause such payment to be made
punctually as and when the same shall become due and payable, whether at
maturity or by declaration or otherwise, and as if such payment were made by the
Borrower.

         SECTION 2. Guarantee unconditional. The obligations of the Guarantor
under this Article 2 shall be unconditional and absolute and, without limiting
the generality of the foregoing, shall not be released, discharged or otherwise
affected by:

         (a) any extension, renewal, settlement, compromise, waiver or release
in respect of any obligation of any other Obligor under any Financing Document,
by operation of law or otherwise;

         (b) any modification or amendment of or supplement to any Financing
Document (other than as specified in an amendment or waiver of this Subsidiary
Guarantee effected in accordance with Section 3);

         (c) any modification, amendment, waiver, release, non-perfection or
invalidity of any direct or indirect security, or of any guaranty or other
liability of any third party, for any obligation of any other Obligor under any
Financing Document;

         (d) any change in the corporate existence, structure or ownership of
any other Obligor, or any insolvency, bankruptcy, reorganization or other
similar proceeding affecting any other Obligor or its assets or any resulting
release or discharge of any obligation of any other Obligor contained in any
Financing Document [(including, without limitation, any change in the identity
of the Borrower from Tyco US to Tyco Luxembourg as contemplated by Section 3.04
of the Credit Agreements)] [to be included in Subsidiary Guarantees issued while
Tyco US is the Borrower];


                                       2
<PAGE>   100
         (e) the existence of any claim, set-off or other rights which the
Guarantor may have at any time against any other Obligor, the Agent, any Bank or
any other Person, whether or not arising in connection with the Financing
Documents; provided that nothing herein shall prevent the assertion of any such
claim by separate suit or compulsory counterclaim;

         (f) any invalidity or unenforceability relating to or against any other
Obligor for any reason of any Financing Document, or any provision of applicable
law or regulation purporting to prohibit the payment by any other Obligor of the
principal of or interest on any Promissory Note or any other amount payable by
any other Obligor under any Financing Document; or

         (g) any other act or omission to act or delay of any kind by any other
Obligor, the Agent, any Bank or any other Person or any other circumstance
whatsoever that might, but for the provisions of this paragraph, constitute a
legal or equitable discharge of the obligations of the Guarantor under this
Article 2.

         SECTION 3. Limit of Liability. The Guarantor shall be liable under this
Subsidiary Guarantee only for amounts aggregating up to the largest amount that
would not render its obligations hereunder subject to avoidance under Section
548 of the United States Bankruptcy Code or any comparable provisions of any
other applicable law.

         SECTION 4. Discharge; Reinstatement in Certain Circumstances. Subject
to Section 6, the Guarantor's obligations under this Article 2 shall remain in
full force and effect until the Commitments are terminated and the principal of
and interest on the Promissory Notes and all other amounts payable by the
Borrower under the Financing Documents shall have been paid in full. If at any
time any payment of the principal of or interest on any Promissory Note or any
other amount payable by the Borrower under any Financing Document is rescinded
or must be otherwise restored or returned upon the insolvency, bankruptcy or
reorganization of any other Obligor or otherwise, the Guarantor's obligations
under this Article 2 with respect to such payment shall be reinstated at such
time as though such payment had become due but had not been made at such time.

         SECTION 5. Waiver. The Guarantor irrevocably waives acceptance hereof,
presentment, demand, protest and any notice not provided for herein, as well as
any requirement that at any time any action be taken by any Person against any
other Obligor or any other Person.

         SECTION 6. Subrogation and Contribution. (a) The Guarantor irrevocably
waives any and all rights to which it may be entitled, by operation of law or
otherwise, upon making any payment hereunder (i) to be subrogated to the rights
of the payee against the Borrower with respect to such payment or otherwise to
be reimbursed, indemnified or exonerated by any other Obligor in respect thereof
or (ii) to receive any payment, in the nature of contribution or for any other
reason, from any other Obligor with respect to such payment


                                       3
<PAGE>   101
          (b) Notwithstanding the provision of subsection (a) of this Section 6,
the Guarantor shall have and be entitled to (i) all rights of subrogation or
contribution otherwise provided by law in respect of any payment it may make or
be obligated to make under this Subsidiary Guarantee and (ii) all claims (as
defined under Chapter 11 of Title 11 of the United States Code, as amended, or
any successor statute (the "Bankruptcy Code")) it would have against the
Borrower or any other Guarantor (each an "Other Party") in the absence of
subsection (a) of this Section 6 and to assert and enforce the same, in each
case on and after, but at no time prior to, the date (the "Subrogation Trigger
Date") which is one year and five days after the Termination Date if, but only
if, (x) no Default or Event of Default of the type described in Section 6.01(i)
or 6.01(j) of the Credit Agreements with respect to the relevant Other Party has
existed at any time on and after the date of this Subsidiary Guarantee to and
including the Subrogation Trigger Date and (y) the existence of such Guarantor's
rights under this clause (b) would not make such Guarantor a creditor (as
defined in the Bankruptcy Code) of such Other Party in any insolvency,
bankruptcy, reorganization or similar proceeding commenced on or prior to the
Subrogation Trigger Date.

         SECTION 7. Stay of Acceleration. If acceleration of the time for
payment of any amount payable by the Borrower under the Financing Documents is
stayed upon the insolvency, bankruptcy or reorganization of the Borrower, all
such amounts otherwise subject to acceleration under the terms of the Financing
Documents shall nonetheless be payable by the Guarantor hereunder forthwith on
demand by the Agent made at the request of the Required Banks.

Guarantee may be amended or waived if, and only if, such amendment or waiver is
in writing and is signed by the Guarantor and the Agent with the prior written
consent of the Required Banks under the Credit Agreements.

<PAGE>   103
         SECTION 4. Successors and Assigns. This Subsidiary Guarantee is for the
benefit of the Banks and the Agent and their respective successors and assigns
and in the event of an assignment of the Loans, the Promissory Notes or other
amounts payable under the Financing Documents, the rights hereunder, to the
extent applicable to the indebtedness so assigned, shall be transferred with
such indebtedness. All the provisions of this Subsidiary Guarantee shall be
binding upon the Guarantor and its successors and assigns.

         SECTION 5. Taxes. All payments by the Guarantor hereunder shall be made
free and clear of Taxes in accordance with Section 8.04 of the Credit
Agreements. If the Guarantor is organized under the laws of, or has its
principal place of business in, a jurisdiction outside the United States, this
Section 5 shall be modified in a manner satisfactory to the Agent and the
Guarantor to indemnify for any foreign taxes which may be applicable.

         SECTION 6. Effectiveness; Termination. (a) This Agreement shall become
effective when the Agent shall have received a counterpart hereof signed by the
Guarantor.

         (b) The Guarantor may at any time elect to terminate this Subsidiary
Guarantee and its obligations hereunder, provided that, after giving effect
thereto, no Default shall have occurred and be continuing; and provided further
that subsequent to the New Borrower Date, this Subsidiary Guarantee may not be
so terminated in respect of any Guarantor which is a Required Significant
Subsidiary. If the Guarantor so elects to terminate this Subsidiary Guarantee,
it shall give the Agent notice to such effect, which notice shall be accompanied
by a certificate of a Responsible Officer to the effect that, after giving
effect to such termination, no Default shall have occurred and be continuing.
The Agent may if it so elects conclusively rely on such certificate. Upon
receipt of such notice and such certificate, unless the Agent determines that a
Default shall have occurred and be continuing, the Agent shall promptly deliver
to the Guarantor the counterpart of this Subsidiary Guarantee delivered to the
Agent pursuant to Section 6(a), and upon such delivery this Subsidiary Guarantee
shall terminate and the Guarantor shall have no further obligations hereunder.

         SECTION 7. GOVERNING LAW; SUBMISSION TO JURISDICTION. THIS SUBSIDIARY
GUARANTEE SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE
STATE OF NEW YORK. THE GUARANTOR HEREBY SUBMITS TO THE NONEXCLUSIVE JURISDICTION
OF THE UNITED STATES DISTRICT COURT FOR THE SOUTHERN DISTRICT OF NEW YORK AND OF
ANY NEW YORK STATE COURT SITTING IN NEW YORK CITY FOR PURPOSES OF ALL LEGAL
PROCEEDINGS ARISING OUT OF OR RELATING TO THIS SUBSIDIARY GUARANTEE OR THE
TRANSACTIONS CONTEMPLATED HEREBY. THE GUARANTOR IRREVOCABLY WAIVES, TO THE
FULLEST EXTENT PERMITTED BY LAW, ANY OBJECTION WHICH IT MAY NOW OR HEREAFTER
HAVE TO THE LAYING OF THE VENUE OF ANY SUCH PROCEEDING BROUGHT IN SUCH A COURT
AND ANY CLAIM THAT ANY SUCH PROCEEDING BROUGHT IN SUCH A COURT HAS BEEN BROUGHT
IN AN INCONVENIENT FORUM.

            [Form of Opinion of Counsel for the Subsidiary Guarantor]


To the Banks and the Agent
Named on the Attached Distribution List
c/o Morgan Guaranty Trust Company
of New York, as Agent
60 Wall Street
New York, New York 10260

Ladies and Gentlemen:

         I am the [Associate] General Counsel of [Name of Borrower], a
__________ corporation (the "Borrower"), and have acted as counsel for [name of
Subsidiary Guarantor] (the "Guarantor"), and am rendering this opinion in
connection with that certain Subsidiary Guarantee (the "Subsidiary Guarantee"),
dated as of __________, entered into by the Guarantor, pursuant to that certain
364-Day Credit Agreement and that certain Extendible 364-Day Credit Agreement
(collectively, the "Credit Agreements"), each dated as of February 13, 1998,
among the Borrower, the banks listed on the signature pages thereof (the
"Banks") and Morgan Guaranty Trust Company of New York, as Agent. Each term
defined in the Subsidiary Guarantee and used herein, but not otherwise defined
herein, has the meaning ascribed thereto in the Subsidiary Guarantee. This
opinion is being delivered to you pursuant to the Credit Agreements.

         In connection with the opinion set forth herein, I have reviewed the
Credit Agreements, the Promissory Notes and the Subsidiary Guarantee and have
examined originals or copies, certified or otherwise identified to my
satisfaction, of (i) the [Certificate of Incorporation] and By-laws of the
Guarantor, each as in effect on the date hereof and (ii) such other documents,
records, certificates and instruments as I have deemed relevant and necessary as
a basis for the opinion hereinafter expressed.

         In my examination, I have assumed the genuineness of all signatures on
original documents, the authenticity of all documents submitted to me as
originals, the conformity to the originals of all copies submitted to be as
certified, conformed or photostatic copies, and the authenticity of the
originals of such copies. As to various questions of fact material to this
opinion, I have relied, without independent investigation or verification, upon
statements, representations and certificates of officers and other
representatives of the Guarantor and certificates of public officials.
<PAGE>   107
         Based upon the foregoing, and subject to the qualifications and
assumptions set forth herein, it is my opinion that:

         (1)      The Guarantor is a corporation duly incorporated, validly
existing and in good standing under the laws of _________________.

         (2)      The execution, delivery and performance by the Guarantor of
the Subsidiary Guarantee (a) are within the Guarantor's corporate powers; (b)
have been duly authorized by all necessary corporate action on the part of the
Guarantor; (c) require no action by or in respect of, or filing on the part of
the Guarantor with, any governmental body, agency or official, in each case, on
the part of the Guarantor; and (d) do not contravene, or constitute a default by
the Guarantor under, any provision of (i) applicable law or regulation, (ii) the
certificate of incorporation or by-laws of the Guarantor or, (iii) any agreement
or instrument evidencing or governing Debt of the Guarantor, or any other
material agreement, judgment, injunction, order, decree or other instrument
binding upon the Guarantor.

         (3)      The Subsidiary Guarantee constitutes a valid and binding
obligation of the Guarantor.

         (4)      The Guarantor is not an "investment company" within the
meaning of the Investment Company Act of 1940, as amended.

         The opinion set forth herein is subject to the following qualifications
and limitations:

         (a)      The enforceability of the Subsidiary Guarantee may be subject
to or limited by bankruptcy, insolvency, reorganization, arrangement,
moratorium, fraudulent conveyance or transfer or other similar laws and court
decisions, now or hereafter in effect, relating to or affecting the rights of
creditors generally.

         (b)      The enforceability of the Subsidiary Guarantee is or will be
subject to the application of and may be limited by general principles of equity
including, without limitation, concepts of materiality, reasonableness, good
faith and fair dealing (regardless of whether considered in a proceeding in
equity or at law). Such principles of equity are of general application, and in
applying such principles a court, among other things, might not allow a creditor
to accelerate maturity of a debt under certain circumstances including, without
limitation, upon the occurrence of a default deemed immaterial, or might decline
to order the Guarantor to perform covenants. Such principles as applied by a
court might include a requirement that a creditor act with reasonableness and in
good faith. Thus, I express no opinion as to the validity or enforceability of
(i) provisions restricting access to legal or equitable remedies, such as the
specific performance of executory covenants, (ii) provisions that purport to
establish evidentiary standards, (iii) provisions relating to waivers,
severability, set-off, or delay or omission of enforcement of rights or
remedies, and (iv) provisions purporting to convey rights to persons other than
parties to the Subsidiary Guarantee.


                                       2
<PAGE>   108
         (c)      The remedy of specific performance and injunctive and other
forms of equitable relief are subject to equitable defenses and to the
discretion of the court before which any proceeding therefor may be brought.

         (d)      I have not been requested to render, and with your permission
I do not express, any opinion as to the applicability to any provisions of the
Subsidiary Guarantee, of Section 548 of the Federal Bankruptcy Code, Article 10
of the New York Debtor & Creditor Law, or any other fraudulent conveyance,
insolvency or transfer laws or any court decisions with respect to any of the
foregoing.

         I call your attention to the fact that I am admitted to practice law
only in the State of New York and the Commonwealth of Massachusetts, and, in
rendering the foregoing opinion, I do not express any opinion as to any laws
other than the laws of [the jurisdiction of incorporation of the Guarantor], the
State of New York, the Commonwealth of Massachusetts and the Federal laws of the
United States of America.

         The opinion expressed herein is based upon the laws in effect on the
date hereof, and I assume no obligation to revise or supplement this opinion
should any such law be changed by legislative action, judicial decision, or
otherwise.

         This opinion is being delivered to you solely for your benefit in
connection with the Subsidiary Guarantee, and neither this opinion nor any part
hereof may be delivered to, or used, referred to or relied upon, by any other
person or for any other purpose without my express prior written consent, except
that any person who is a permitted successor or assign of a Bank in accordance
with the provisions of the Credit Agreement may rely upon this opinion as if it
were specifically addressed and delivered to such person on the date hereof.

                                         Very truly yours,


                                       3

                           Form of Opinion of Counsel
                            for the Parent Guarantor


To the Banks and the Agent
   named on Schedule 1 to this Opinion
c/o Morgan Guaranty Trust Company of New York (as Agent)
60 Wall Street
New York, NY 10260

Dear Sirs,

         Re: TYCO INTERNATIONAL LTD. (THE "COMPANY")

         We have been instructed by the Company to address this opinion to you
in connection with the Parent Guarantee, dated as of February 13, 1998 (the
"Guarantee"), entered into by the Company in connection with all principal of
and interest on amounts loaned to the Borrower under the Financing Documents.

         Unless otherwise defined therein, terms defined in the Guarantee have
the same meanings when used in this opinion.

         For the purpose of this opinion, we have been supplied with and have
reviewed, and relied upon the following documents:

                  (A)      a copy of the executed US $500,000,000 Extendible
         364-Day Credit Agreement dated as of February 13, 1998 among the
         Borrower, the Banks listed on the signature pages thereof and the
         Agent;

                  (B)      a copy of the executed US $1,750,000,000 364-Day
         Credit Agreement dated as of February 13, 1998 among the Borrower, the
         Banks listed on the signature pages thereof and the Agent;

                  (C)      a copy of the executed Subsidiary Guarantees;

                  (D)      a copy of the executed Promissory Notes;

The Documents referred to in (a), (b) and (d) inclusive are together referred to
as the "Financing Documents".
<PAGE>   110
                  (E)      a copy of the executed Guarantee;

                  (F)      certified copies of the Certificate of Incorporation,
         the Certificate evidencing the change of name of the Company from ADT
         Limited to TYCO International Ltd. and the Memorandum of Association
         and the Bye-laws of the Company;

                  (G)      a certified copy of the minutes of a meeting of the
         Board of Directors of the Company held on [ ], 199_ (the
         "Resolutions"); and

                  (H)      a certified copy of the Share Certificate evidencing
         ownership by the Company of [the Borrower].

         We also examined and relied upon:

                  (A)      A Certificate of Compliance issued by the Registrar
         of Companies on Bermuda in respect of the Company on [ ] February,
         1998; and

                  (B)      Our searches of the documents of public record in
         relation to the Company maintained by the Registrar of Companies in
         Bermuda made on [ ] February, 1998 and of the Causes Book maintained by
         the Registrar of the Supreme Court of Bermuda made on the same date
         (the "Searches").

         In giving this opinion, we have assumed:

                           (1)      the capacity, power and authority of each of
                  the parties other than the company to execute, deliver and
                  perform its obligations under and the due execution and
                  delivery by all parties other than the Company of the
                  Financing Documents and the Guarantee;

                           (2)      that each party, other than the Company, has
                  duly authorised, executed, delivered and taken such other
                  action as may be required by such party to enter into and
                  perform the Financing Documents and the Guarantee in the form
                  of the execution copies we have reviewed for the purpose of
                  this opinion without alteration which is material to this
                  opinion and that all such actions were duly authorised when
                  taken;

                           (3)      that no authorisation or approval by, or
                  filing with, any governmental or regulatory authority, other
                  than such authorisations, approvals and filings as each party
                  other than the Company has obtained or made, is necessary for
                  such party to duly execute and deliver, or to duly perform all
                  of its obligations under the Financing Documents and the
                  Guarantee, or for the validity and enforceability of the
                  Financing Documents and the Guarantee;


                                       2
<PAGE>   111
                           (4)      that each of the Financing Documents and the
                  Guarantee constitutes the legal, valid and binding obligation
                  of each party to it, other than the Company, and is
                  enforceable against each such party in accordance with its
                  terms;

                           (5)      that the Financing Documents are legal,
                  valid and binding under the laws by which they are expressed
                  to be governed and that the Guarantee is legal, valid and
                  binding under the laws of the State of New York by which it is
                  expressed to be governed;

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

                           (7)      that there is no provision of the law of any
                  jurisdiction, other than Bermuda, which would have any
                  implication in relation to the opinions herein expressed;

                           (8)      the genuineness of all signatures on the
                  documents which we have examined;

                           (9)      the conformity to original documents of all
                  documents produced to us as copies and the authenticity of all
                  original documents which, or copies of which, have been
                  submitted to us;

                           (10)     the accuracy and completeness of all factual
                  representations made in the Financing Documents, the
                  Guarantee, the Resolutions and any certificates or other
                  documents which we have examined and upon which we have
                  relied;

                           (11)     that the Resolutions are in full force and
                  effect and have not been rescinded or altered in any way
                  material to this opinion; and

                           (12)     that the Company is entering into its
                  obligations under the Guarantee in good faith and for the
                  purpose of carrying on its commercial business in the ordinary
                  course thereof and that there are reasonable grounds for
                  believing that the transactions contemplated by the Financing
                  Documents will benefit the Company.

         Based upon and subject to the foregoing, and subject to the
reservations set out below, to matters not disclosed to us and matters of fact
which would affect the conclusion set out below and having regard to such legal
considerations as we deem relevant, we are of the opinion that:


                                       3
<PAGE>   112
         (i).     The Company is a company duly incorporated, duly organised and
validly existing under the laws of Bermuda. The Memorandum of Association of the
Company has been duly filed in the office of the Registrar of Companies of
Bermuda and no other filing, recording, publishing or other act is necessary or
appropriate in Bermuda in connection with the transaction as described in the
Guarantee except those which have been duly made or performed.

         (ii).    The Company has the corporate power and authority to enter
into and perform the Guarantee and has taken all corporate action required on
its part to authorise the execution, delivery and performance of the guarantee.

         (iii).   The execution, delivery and performance of the Guarantee by
the Company (i) does not and will not violate the Certificate of Incorporation,
Memorandum of Association or Bye-laws of the Company; (ii) conflict with the
Companies Act 1981 or any other law or governmental rule or regulation published
by the Bermuda Government which is applicable to the Company; and (iii) as far
as can be ascertained from the Searches (which are not conclusive) does not and
will not violate or conflict with any judgment, order, decree, injunction or
award of any authority, agency or court in Bermuda to which the Company is
subject.

         (iv).    The obligations of the Company as set out in the Guarantee
constitute, legal, valid and binding obligations of the Company.

         (v).     The Company having been designated as non-resident for the
purposes of the Exchange Control Act 1972, it is not necessary for the consent
of any authority or agency in Bermuda to be obtained to enable the Company to
enter into and perform its obligations set out in the Guarantee.

         (vi).    The obligations of the Company under the Guarantee will rank
at least pari passu in priority of payment with all other unsecured
unsubordinated indebtedness of the Company other than indebtedness which is
preferred by virtue of any provision of Bermuda law of general application.

         (vii).   As far as can be ascertained from the Searches (which are not
conclusive), no litigation, arbitration or administrative proceedings of or
before any court, arbitrator or governmental instrumentality of or in Bermuda
is, to the best of our knowledge, pending with respect to the Company in
connection with the Guarantee or the transactions contemplated thereby.

         (viii).  The Company will be permitted to make all payments under the
Guarantee free of any deduction or withholding therefrom in Bermuda and such
payments will not be subject to any tax imposed by the Government of Bermuda or
any taxing authority thereof or therein.


                                       4
<PAGE>   113
         (ix).    The entry into, performance and enforcement of the Guarantee
will not give rise to any registration fee or to any stamp, excise or other
similar tax imposed by the Government of Bermuda or any taxing authority thereof
or therein.

         (x).     Subject to paragraph (12) and reservation (f) below, it is not
necessary or advisable under the laws of Bermuda in order to ensure the
validity, effectiveness or enforceability or admissibility in evidence of the
Guarantee that the Guarantee be filed, registered or recorded with any Court,
public office or other Bermuda regulatory authority.

         (xi).    The choice of the laws of the State of New York to govern the
Guarantee is a proper, valid and binding choice of law and will be recognised
and applied by the courts of Bermuda provided that the point is specifically
pleaded and that such choice of law is a valid and binding choice of law under
the laws of the State of New York.

         (xii).   A final and conclusive judgement obtained in the Courts of the
State of New York or Federal Courts of the United States of America against the
Company based upon the Guarantee under which a sum of money is payable (other
than a sum of money payable in respect of taxes or other charges of a like
nature or in respect of a fine or other penalty or in respect of Multiple
Damages as defined in the Protection of Trading Interest Act, 1981) may be the
subject of enforcement proceedings in the Supreme Court of Bermuda, without
re-examination of the merits, under the Common Law Doctrine of Obligation. A
final opinion as to the availability of this remedy should be sought when the
facts surrounding the foreign judgment are known but, on general principles, we
would expect such an application to be successful provided that:

                  (A)      the Court which gave the judgment was competent to
         hear the action in accordance with private international law principles
         as applied in Bermuda;

                  (B)      the judgment has not been obtained by fraud;

                  (C)      the judgment is not and its enforcement would not be
         contrary to public policy of Bermuda;

                  (D)      the judgment has not been obtained in proceedings
         contrary to natural justice; and

                  (E)      the correct procedures under the laws of Bermuda are
         duly complied with.

         Neither the Company nor any of its property or assets (or any portion
thereof) enjoys, under the laws of Bermuda, immunity from suit, execution,
attachment or other legal process in any proceedings in Bermuda in connection
with the Guarantee.

         Our reservations are as follows:

         (a)      We are admitted to practise law in the Islands of Bermuda and
we express no opinion as to any law other than Bermuda law and none of the
opinions expressed herein relates to compliance with or matters governed by the
laws of any jurisdiction except Bermuda.

         (b)      Where an obligation is to be performed in a jurisdiction other
than Bermuda, the Courts of Bermuda may refuse to enforce it to the extent that
such performance would be illegal or contrary to public policy under the laws of
such other jurisdiction.

         (c)      We express no opinion as to the availability of equitable
remedies, such as specific performance or injunctive relief, or as to matters
which are within the discretion of the Courts of Bermuda such as the award of
costs or questions relating to forum non-conveniens. Further, we express no
opinion as to the validity or binding effect of any waiver of or obligation to
waive any provision of law (whether substantive or procedural) or any right or
remedy arising through circumstances not known at the time of entering into the
Financing Documents and the Guarantee.

         (d)      We express no opinion as to the validity or the binding effect
of any obligations of the Borrower in the Financing Documents which provide for
the payment by the Borrower of a higher rate of interest on overdue amounts than
on amounts which are current. A Bermuda Court, even if it were applying the laws
of the State of New York might not give effect to such provision as being
contrary to public policy if it could be established that the amount expressed
as being payable was such that the provision was in the nature of a penalty;
that is to say a requirement for a stipulated sum to be paid irrespective of, or
necessarily greater than, the loss likely to be sustained. The Court will
determine and award what it considers to be reasonable damages. Section 9 of The
Interest and Credit Charges (Regulations) Act 1975 provides that the Bermuda
Courts have discretion as to the amount of interest if any payable on the amount
of a judgment after the date of judgment. If the Court does not exercise that
discretion, then interest will accrue at the statutory rate which is currently
7% per annum.

         (e)      The obligations of the Company under the Guarantee will be
subject to any laws from time to time in effect relating to bankruptcy,
insolvency or liquidation or any other laws or other legal procedures affecting
generally the enforcement of creditors' rights and may also be the subject of
the statutory limitation of the time within which such proceedings may be
brought.

         (f)      To the extent that the Financing Documents, the Guarantee or
the transactions contemplated thereunder, create or give rise to the creation of
any charge over any assets of the Company, such charge will be registerable
under Part V of The Companies Act 1981 of Bermuda. The fee payable for
registration of a charge is $425.00. Registration is not compulsory and there is
no time limit within which it must be effected. Under Section 55 of the
Companies Act, any charge registered will have priority based on the date that
it is registered and not on the date of its creation and will have such priority
over any unregistered charge. Accordingly, it is advisable to register any such
charge.

         (g)      Any provision in the Financing Documents or the Guarantee that
certain calculations and/or certificates will be conclusive and binding will not
be effective if such calculations are fraudulent or erroneous on their face and
will not necessarily prevent enquiry into the merits of any claim by an
aggrieved party.

         (h)      Where a party is vested with a discretion or may determine a
matter in its opinion, such discretion may have to be exercised reasonably or
such an opinion may have to be based on reasonable grounds.

         (i)      Searches in the register of companies at the office of the
Registrar of Companies and in the Supreme Court Causes Book at the Registry of
the Supreme Court are not conclusive and it should be noted that the register of
companies and the Supreme Court Causes Book do not reveal:

                  (i)      whether an application to the Supreme Court for the
         appointment of a receiver or manager has been presented;

                  (ii)     details of matters which have been lodged for
         registration but have not actually been registered or to the extent
         they have been registered have not been disclosed or appear in the
         public records at the date the search is concluded;

                  (iii)    details of matters which should have been lodged for
         registration but have not been lodged for registration at the date the
         search is concluded; or

                  (iv)     whether a receiver or manager has been appointed
         privately out of the Supreme Court pursuant to the provisions of a
         debenture or other security, unless notice of the fact has been entered
         in the register of charges in accordance with the provisions of the
         Act.

         (j)      A Bermuda Court may refuse to give effect to any provisions of
the Financing Documents or Guarantee in respect of costs of unsuccessful
litigation brought before the Court or where that Court has itself made an order
for costs.


         This opinion is issued on the basis that it will be governed by and
construed in accordance with the provisions of Bermuda law and it is limited to
and is given on the basis of the current law and practice in Bermuda and will
not give rise to action in any other jurisdiction. It is issued solely for your
benefit for the purpose of the transactions described in the Guarantee and it is
not to be relied upon by any other person (other than permitted assigns and
transferees under the Financing Documents), or for any other purpose, without
our prior written consent.

                           Yours faithfully,


                                       7

                             NEW BORROWER AGREEMENT



         AGREEMENT dated as of ___________ among TYCO INTERNATIONAL (US) INC., a
Massachusetts corporation ("Tyco US"), TYCO GROUP S.a.r.l., a Luxembourg company
("Tyco Luxembourg"), and MORGAN GUARANTY TRUST COMPANY OF NEW YORK, as Agent
(the "Agent").

                                R E C I T A L S:

         WHEREAS, Tyco US is a party to a 364-Day Credit Agreement dated as of

time, the "Credit Agreement") with the Banks listed therein and the Agent; and

         WHEREAS, any Loans made to Tyco US by the Banks under the Credit
Agreement will be prepaid in full not later than the date of effectiveness
hereof; and

         WHEREAS, Tyco US and Tyco Luxembourg have elected that Tyco Luxembourg
shall become the Borrower under the Credit Agreement and that Tyco US shall
cease to be the Borrower thereunder;

         NOW, THEREFORE, in consideration of the foregoing and the mutual
agreements contained herein, the parties hereto agree as follows:

         SECTION 1. Definitions. All capitalized terms not otherwise defined
herein shall have the meanings set forth in the Credit Agreement.

         SECTION 2. New Borrower. Upon the satisfaction of the conditions
referred to in Section 3.04 of the Credit Agreement, (i) each of the Banks shall
make a Loan to Tyco Luxembourg on the terms and conditions set forth in the
Credit Agreement, (ii) the proceeds of such Loans shall fund to the extent
necessary an inter-company loan by Tyco Luxembourg to Tyco US, which
inter-company loan shall fund in whole or in part the repayment of all loans to
Tyco US under the Credit Agreement and the Existing Agreements, (iii) Tyco US
shall execute a promissory note in favor of Tyco Luxembourg, in form reasonably
satisfactory to Tyco Luxembourg, to evidence such inter-company loans, (iv) Tyco

<PAGE>   117
liabilities and obligations under the Credit Agreement and the Notes to the
extent such liabilities and obligations arise from and after the effectiveness
of this Agreement and shall cease to be a party to the Credit Agreement. Nothing
in this Section shall affect the obligations of Tyco US as a Subsidiary
Guarantor.

         SECTION 3. Judicial Proceedings. (a) Consent to Jurisdiction. Tyco
Luxembourg irrevocably submits to the non-exclusive jurisdiction of any federal
or New York State court sitting in New York City over any suit, action or
proceeding arising out of or relating to the Financing Documents. Tyco
Luxembourg irrevocably waives, to the fullest extent permitted by law, any
objection which it may now or hereafter have to the laying of the venue of any
such suit, action or proceeding brought in such court and any claim that any
suit, action or proceeding brought in such court has been brought in an
inconvenient forum. Tyco Luxembourg agrees that a final judgment in any such
suit, action or proceeding brought in such a court shall be conclusive and
binding upon it and will be given effect in Luxembourg to the fullest extent
permitted by applicable law and may be enforced in any federal or New York State
court sitting in New York City (or any other courts to the jurisdiction of which
Tyco Luxembourg is or may be subject) by a suit upon such judgment, provided
that service of process is effected upon it in one of the manners specified
herein or as otherwise permitted by law.

         (b)      Appointment of Agent for Service of Process. Tyco Luxembourg
hereby irrevocably designates and appoints CT Corporation System having an
office on the date hereof at 1633 Broadway, New York, New York 10019 as its
authorized agent, to accept and acknowledge on its behalf, service or any and
all process which may be served in any suit, action or proceeding of the nature
referred to in subsection (a) above in any federal or New York State court
sitting in New York City. Tyco Luxembourg represents and warrants that such
agent has agreed in writing to accept such appointment and that a true copy of
such designation and acceptance has been delivered to the Agent. Such
designation and appointment shall be irrevocable until all principal and
interest and all other amounts payable under the Financing Documents shall have
been paid in full in accordance with the provisions hereof. If such agent shall
cease so to act, Tyco Luxembourg covenants and agrees to designate irrevocably
and appoint without delay another such agent satisfactory to the Agent and to
deliver promptly to the Agent evidence in writing of such other agent's
acceptance of such appointment.

         (c)      Service of Process. Tyco Luxembourg hereby consents to process
being served in any suit, action, or proceeding of the nature referred to in
subsection (a) above in any federal or New York State court sitting in New York
City by service of process upon the agent of Tyco Luxembourg, as the case may
be, for service of process in such jurisdiction appointed as provided in
subsection (b) above; provided that, to the extent lawful and possible, written
notice of said service upon such agent shall be mailed by registered airmail,
postage prepaid, return receipt requested, to Tyco Luxembourg at its address
specified on the signature pages hereof or to any other address of which Tyco
Luxembourg shall have given written notice to the Agent. Tyco Luxembourg
irrevocably waives, to the fullest extent permitted by law, all claim of error
by reason of any such service and agrees that such service shall be deemed in
every respect effective


                                       2
<PAGE>   118
service of process upon Tyco Luxembourg in any such suit, action or proceeding
and shall, to the fullest extent permitted by law, be taken and held to be valid
and personal service upon and personal delivery to Tyco Luxembourg.

         (d)      No Limitation on Service or Suit. Nothing in this Section
shall affect the right of the Agent or any Bank to serve process in any other
manner permitted by law or limit the right of the Agent or any Bank to bring
proceedings against Tyco Luxembourg in the courts of any jurisdiction or
jurisdictions.

         SECTION 4. Governing Law. This Agreement shall be governed by and
construed in accordance with the laws of the State of New York.

         SECTION 5. Counterparts; This Agreement may be signed in any number of
counterparts, each of which shall be an original, with the same effect as if the
signatures thereto and hereto were upon the same instrument.

         IN WITNESS WHEREOF, the parties have caused this Agreement to be
executed and delivered by their duly authorized officers as of the date first
above written.

                                    TYCO INTERNATIONAL (US) INC.

9:30 A.M. (New York City time) on the proposed date of Borrowing, in the case of
an Absolute Rate Auction (or, in either case, such other time or date as the
Borrower and the Agent shall have mutually agreed and shall have notified to the
Banks not later than the date of the Money Market Quote Request for the first
LIBOR Auction or Absolute Rate Auction for which such change is to be
effective); provided that Money Market Quotes submitted by the Agent (or any
affiliate of the Agent) in the capacity of a Bank may be submitted, and may only
be submitted, if the Agent or such affiliate notifies the Borrower of the terms
of the offer or offers contained therein not later than (x) one hour prior to
the deadline for the other Banks, in the case of a LIBOR Auction or (y) 15
minutes prior to the deadline for the other Banks, in the case of an Absolute
Rate Auction. Subject to Articles 3 and 6, any Money Market Quote so made shall
be irrevocable except with the written consent of the Agent given on the
instructions of the Borrower.

         (ii) Each Money Market Quote shall be in substantially the form of
         Exhibit D hereto and shall in any case specify:

                           (A) the proposed date of Borrowing and the Interest
                  Period therefor,

                           (B) the principal amount of the Money Market Loan for
                  which each such offer is being made, which principal amount
                  (w) may be greater than or less than the Commitment of the
                  quoting Bank, (x) must be $5,000,000 or a larger multiple of
                  $1,000,000, (y) may not exceed the principal amount of Money
                  Market Loans for which offers were requested and (z) may be
                  subject to an aggregate limitation as to the principal amount
                  of Money Market Loans for which offers being made by such
                  quoting Bank may be accepted,

                           (C) in the case of a LIBOR Auction, the margin above
                  or below the applicable London Interbank Offered Rate (the
                  "Money Market Margin") offered for each such Money Market
                  Loan, expressed as a percentage (specified to the nearest
                  1/10,000th of 1%) to be added to or subtracted from the
                  applicable London Interbank Offered Rate,

                           (D) in the case of an Absolute Rate Auction, the rate
                  of interest per annum (specified to the nearest 1/10,000th of
                  1%) (the "Money Market Absolute Rate") offered for each such
                  Money Market Loan, and

                           (E) the identity of the quoting Bank.

A Money Market Quote may set forth up to five separate offers by the quoting
Bank with respect to each Interest Period specified in the related Invitation
for Money Market Quotes.

         (iii) Any Money Market Quote shall be disregarded if it:

                           (A) is not substantially in conformity with Exhibit D
                  hereto or does not specify all of the information required by
                  subsection 2.03(d)(ii);

                           (B) contains qualifying, conditional or similar
                  language;

                           (C) proposes terms other than or in addition to those
                  set forth in the applicable Invitation for Money Market
                  Quotes; or

                           (D) arrives after the time set forth in subsection
                  2.03(d)(i).

          (e) Notice to Borrower. The Agent shall promptly notify the Borrower
of the terms (x) of any Money Market Quote submitted by a Bank that is in
accordance with subsection 2.03(d) and (y) of any Money Market Quote that
amends, modifies or is otherwise inconsistent with a previous Money Market Quote
submitted by such Bank with respect to the same Money Market


                                       19
<PAGE>   25
Quote Request. Any such subsequent Money Market Quote shall be disregarded by
the Agent unless such subsequent Money Market Quote is submitted solely to
correct a manifest error in such former Money Market Quote. The Agent's notice
to the Borrower shall specify (A) the aggregate principal amount of Money Market
Loans for which offers have been received for each Interest Period specified in
the related Money Market Quote Request, (B) the respective principal amounts and
Money Market Margins or Money Market Absolute Rates, as the case may be, so
offered and (C) if applicable, limitations on the aggregate principal amount of
Money Market Loans for which offers in any single Money Market Quote may be
accepted.

          (f) Acceptance and Notice by Borrower. Not later than 10:30 A.M. (New
York City time) on (x) the third Euro-Dollar Business Day prior to the proposed
date of Borrowing, in the case of a LIBOR Auction or (y) the proposed date of
Borrowing, in the case of an Absolute Rate Auction (or, in either case, such
other time or date as the Borrower and the Agent shall have mutually agreed and
shall have notified to the Banks not later than the date of the Money Market
Quote Request for the first LIBOR Auction or Absolute Rate Auction for which
such change is to be effective), the Borrower shall notify the Agent of its
acceptance or non-acceptance of the offers so notified to it pursuant to
subsection 2.03(e) (and the failure of the Borrower to give such notice by such
time shall constitute non-acceptance) and the Agent shall promptly notify each
affected Bank. In the case of acceptance, such notice (a "Notice of Money Market
Borrowing") shall specify the aggregate principal amount of offers for each
Interest Period that are accepted. The Borrower may, but shall not be obligated
to, accept any Money Market Quote in whole or in part; provided that:

                  (i) the aggregate principal amount of each Money Market
         Borrowing may not exceed the applicable amount set forth in the related
         Money Market Quote Request,

                  (ii) the principal amount of each Money Market Borrowing must
         be $10,000,000 or a larger multiple of $1,000,000,

                  (iii) acceptance of offers may only be made on the basis of
         ascending order of Money Market Margins or Money Market Absolute Rates,
         as the case may be, in each case beginning with the lowest rate so
         offered, and

                  (iv) the Borrower may not accept any offer where the Agent has
         advised the Borrower that such offer is described in subsection
         2.03(d)(iii) or that otherwise fails to comply with the requirements of
         this Agreement.

          (g) Allocation by Agent. If offers are made by two or more Banks with
the same Money Market Margins or Money Market Absolute Rates, as the case may
be, for a greater aggregate principal amount than the amount in respect of which
such offers are accepted for the related Interest Period, the principal amount
of Money Market Loans in respect of which such offers are accepted shall be
allocated by the Agent among such Banks as nearly as possible (in multiples of
$1,000,000, as the Agent may deem appropriate) in proportion to the aggregate
principal


                                       20
<PAGE>   26
amounts of such offers. Determinations by the Agent of the amounts of Money
Market Loans shall be conclusive in the absence of manifest error.

         SECTION 2.04. Notice to Banks; Funding of Loans.

         (a) Upon receipt of a Notice of Borrowing, the Agent shall promptly
notify each Bank of the contents thereof and of such Bank's share (if any) of
such Borrowing and such Notice of Borrowing shall not thereafter be revocable by
the Borrower.

         (b) Not later than 2:00 P.M. (New York City time) on the date of each
Borrowing, each Bank participating therein shall make available its share of
such Borrowing, in Federal or other funds immediately available in New York
City, to the Agent at its address referred to in Section 9.01. Unless the Agent
determines that any applicable condition specified in Article 3 has not been
satisfied or waived in accordance with Section 9.05, the Agent will make the
funds so received from the Banks available to the Borrower no later than 3:00
P.M. (New York City time) on such date, in Federal or other funds immediately
available in New York City, as directed by the Borrower.

         (c) If any Bank makes a new Loan hereunder on any day on which the
Borrower is to repay all or any part of an outstanding Loan from such Bank, such
Bank shall apply the proceeds of its new Loan to make such repayment and only an
amount equal to the difference (if any) between the amount being borrowed and
the amount being repaid shall be made available by such Bank to the Agent as
provided in subsection 2.04(b), 2.04(c), or remitted by the Borrower to the
Agent as provided in Section 2.12, as the case may be.

         (d) Unless the Agent shall have received notice from a Bank prior to
the date of any Borrowing that such Bank will not make available to the Agent
such Bank's share of such Borrowing, the Agent may assume that such Bank has
made such share available to the Agent on the date of such Borrowing in
accordance with subsection (b) and (c) of this Section 2.04 and the Agent may,
in reliance upon such assumption, make available to the Borrower on such date a
corresponding amount. If and to the extent that such Bank shall not have so made
such share available to the Agent, such Bank and, if such Bank shall not have
paid such amount to the Agent within two Domestic Business Days of the Agent's
demand therefor, the Borrower severally agree to repay to the Agent forthwith on
demand such corresponding amount together with interest thereon, for each day
from the date such amount is made available to the Borrower until the date such
amount is repaid to the Agent, at the Federal Funds Rate. If such Bank shall
repay to the Agent such corresponding amount, such amount so repaid shall
constitute such Bank's Loan included in such Borrowing for purposes of this
Agreement.

         (e) The failure of any Bank to make any Loan to be made by it on the
date specified therefor shall not relieve any other Bank of any obligation to
make a Loan on such date.

         SECTION 2.05. Promissory Notes. (a) The Loans of each Bank shall be
evidenced by a single Promissory Note payable to the order of such Bank for the
account of its Applicable


                                       21
<PAGE>   27
Lending Office in an amount equal to the aggregate unpaid principal amount of
such Bank's Loans.

          (b) Each Bank may, by notice to the Borrower and the Agent, request
that its Loans of a particular type be evidenced by a separate Promissory Note
in an amount equal to the aggregate unpaid principal amount of such Loans. Each
such Promissory Note shall be in substantially the form of Exhibit A hereto with
appropriate modifications to reflect the fact that it evidences solely Loans of
the relevant type. Each reference in this Agreement to the "Promissory Note" of
such Bank shall be deemed to refer to and include any or all of such Promissory
Notes, as the context may require.

         (c) Upon receipt of each Bank's Promissory Note pursuant to Section
3.01(b), the Agent shall forward such Promissory Note to such Bank. Each Bank
shall record the date, amount, type and maturity of each Loan made by it and the
date and amount of each payment of principal made by the Borrower with respect
thereto, and may, if such Bank so elects in connection with any transfer or
enforcement of its Promissory Note, endorse on the schedule forming a part
thereof appropriate notations to evidence the foregoing information with respect
to each such Loan then outstanding; provided that the failure of any Bank to
make any such recordation or endorsement shall not affect the obligations of the
Borrower hereunder or under the Promissory Notes. Each Bank is hereby
irrevocably authorized by the Borrower so to endorse its Promissory Note and to
attach to and make a part of its Promissory Note a continuation of any such
schedule as and when required.

         SECTION 2.06. Maturity of Loans. (a) Each Committed Loan shall mature,
and the principal amount thereof shall be due and payable (together with
interest accrued thereon), on the Termination Date.

         (b) Each Money Market Loan included in any Money Market Borrowing shall
mature, and the principal amount thereof shall be due and payable (together with
interest accrued thereon), on the last day of the Interest Period applicable to
such Borrowing.

         SECTION 2.07. Interest Rates. (a) Each Base Rate Loan shall bear
interest on the outstanding principal amount thereof, for each day from the date
such Loan is made until it becomes due, at a rate per annum equal to the Base
Rate for each such day. Such interest shall be payable at maturity, quarterly in
arrears on each Quarterly Payment Date prior to maturity and, with respect to
the principal amount of any Base Rate Loan converted to a CD Loan or a Euro-
Dollar Loan, on the date such amount is so converted. Any overdue principal of
or interest on any Base Rate Loan shall bear interest, payable on demand, for
each day from and including the date payment thereof was due to but excluding
the date of actual payment, at a rate per annum equal to the sum of 2% plus the
rate otherwise applicable to Base Rate Loans for each such day.

         (b) Each CD Loan shall bear interest on the outstanding principal
amount thereof, for each day during each Interest Period applicable thereto, at
a rate per annum equal to the sum of the Applicable Margin for each such day
plus the applicable Adjusted CD Rate for such Interest


                                       22
<PAGE>   28
Period; provided that if any CD Loan shall, as a result of the further proviso
to the definition of Interest Period, have an Interest Period of less than 30
days, such CD Loan shall bear interest during such Interest Period at the rate
applicable to Base Rate Loans during such period. Such interest shall be payable
for each Interest Period on the last day thereof and, if such Interest Period is
longer than 90 days, at intervals of 90 days after the first day thereof. Any
overdue principal of or interest on any CD Loan shall bear interest, payable on
demand, for each day from and including the date payment thereof was due to but
excluding the date of actual payment, at a rate per annum equal to the sum of 2%
plus the higher of (i) the sum of the Applicable Margin for each such day plus
the Adjusted CD Rate applicable to such Loan on the day before such payment was
due and (ii) the rate applicable to Base Rate Loans for each such day.

         The "Adjusted CD Rate" applicable to any Interest Period means a rate
per annum determined pursuant to the following formula:

                                            [ CDBR            ]*
                  ACDR     =                [ ----------      ]+ AR
                                            [ 1.00 - DRP      ]

                  ACDR     =        Adjusted CD Rate
                  CDBR     =        CD Base Rate
                  DRP      =        Domestic Reserve Percentage
                  AR       =        Assessment Rate
- ----------
* The amount in brackets being rounded upward, if
necessary, to the next higher 1/100 of 1%

         The "CD BASE RATE" applicable to any Interest Period is the rate of
interest determined by the Agent to be the average (rounded upward, if
necessary, to the next higher 1/100 of 1%) of the prevailing rates per annum bid
at 10:00 A.M. (New York City time) (or as soon thereafter as practicable) on the
first day of such Interest Period by two or more New York certificate of deposit
dealers of recognized standing for the purchase at face value from each CD
Reference Bank of its certificates of deposit in an amount comparable to the
principal amount of the CD Loan of such CD Reference Bank to which such Interest
Period applies and having a maturity comparable to such Interest Period.

         "DOMESTIC RESERVE PERCENTAGE" means for any day that percentage
(expressed as a decimal) which is in effect on such day, as prescribed by the
Board of Governors of the Federal Reserve System (or any successor) for
determining the maximum reserve requirement (including without limitation any
basic, supplemental or emergency reserves) for a member bank of the Federal
Reserve System in New York City with deposits exceeding five billion dollars in
respect of new non-personal time deposits in dollars in New York City having a
maturity comparable to the related Interest Period and in an amount of $100,000
or more. The Adjusted CD Rate shall be adjusted automatically on and as of the
effective date of any change in the Domestic Reserve Percentage.


                                       23
<PAGE>   29
         "ASSESSMENT RATE" means for any day the annual assessment rate in
effect on such day which is payable by a member of the Bank Insurance Fund
classified as adequately capitalized and within supervisory subgroup "A" (or a
comparable successor assessment risk classification) within the meaning of 12
C.F.R. Section 327.4(a) or any successor provision (a "BIF Member") to the
Federal Deposit Insurance Corporation (or any successor) for the Federal Deposit
Insurance Corporation's (or such successor's) insuring time deposits at offices
of such BIF Member in the United States. The Adjusted CD Rate shall be adjusted
automatically on and as of the effective date of any change in the Assessment
Rate.

         (c) Each Euro-Dollar Loan shall bear interest on the outstanding
principal amount thereof, for each day during each Interest Period applicable
thereto, at a rate per annum equal to the sum of the Applicable Margin for each
such day plus the applicable London Interbank Offered Rate for such Interest
Period. Such interest shall be payable for each Interest Period on the last day
thereof and, if such Interest Period is longer than three months, at intervals
of three months after the first day thereof.

         The "LONDON INTERBANK OFFERED RATE" applicable to any Interest Period
means the average (rounded upward, if necessary, to the next higher 1/16 of 1%)
of the respective rates per annum at which deposits in dollars are offered to
each of the Euro-Dollar Reference Banks in the London interbank market at
approximately 11:00 A.M. (London time) two Euro-Dollar Business Days before the
first day of such Interest Period in an amount approximately equal to the
principal amount of the Euro-Dollar Loan of such Euro-Dollar Reference Bank to
which such Interest Period is to apply and for a period of time comparable to
such Interest Period.

          (d) Any overdue principal of or interest on any Euro-Dollar Loan shall
bear interest, payable on demand, for each day from and including the date
payment thereof was due to but excluding the date of actual payment, at a rate
per annum equal to the sum of 2% plus the higher of (i) the sum of the
Applicable Margin for such day plus the London Interbank Offered Rate applicable
to such Loan on the day before such payment was due and (ii) the Applicable
Margin for such day plus the quotient obtained (rounded upward, if necessary, to
the next higher 1/100 of 1%) by dividing (x) the average (rounded upward, if
necessary, to the next higher 1/16 of 1%) of the respective rates per annum at
which one day (or, if such amount due remains unpaid more than three Euro-Dollar
Business Days, then for such other period of time not longer than six months as
the Agent may select) deposits in dollars in an amount approximately equal to
such overdue payment due to each of the Euro-Dollar Reference Banks are offered
to such Euro-Dollar Reference Bank in the London interbank market for the
applicable period determined as provided above by (y) 1.00 minus the Euro-Dollar
Reserve Percentage (or, if the circumstances described in subsection (a) or (b)
of Section 8.01 shall exist, at a rate per annum equal to the sum of 2% plus the
rate applicable to Base Rate Loans for such day).

          (e) Subject to Section 8.01(a), each Money Market LIBOR Loan shall
bear interest on the outstanding principal amount thereof, for each day during
the Interest Period applicable thereto, at a rate per annum equal to the sum of
the London Interbank Offered Rate for such Interest Period (determined in
accordance with Section 2.07(c) as if the related Money Market


                                       24
<PAGE>   30
LIBOR Borrowing were a Committed Euro-Dollar Borrowing) plus (or minus) the
Money Market Margin quoted by the Bank making such Loan in accordance with
Section 2.03. Each Money Market Absolute Rate Loan shall bear interest on the
outstanding principal amount thereof, for each day during the Interest Period
applicable thereto, at a rate per annum equal to the Money Market Absolute Rate
quoted by the Bank making such Loan in accordance with Section 2.03. Such
interest shall be payable for each Interest Period on the last day thereof and,
if such Interest Period is longer than three months, at intervals of three
months after the first day thereof. Any overdue principal of or interest on any
Money Market Loan shall bear interest, payable on demand, for each day from and
including the date payment thereof was due to but excluding the date of actual
payment, at a rate per annum equal to the sum of 2% plus the Base Rate for each
such day.

         (f) The Agent shall determine each interest rate applicable to the
Loans hereunder. The Agent shall give prompt notice to the Borrower and the
participating Banks of each rate of interest so determined, and its
determination thereof shall be conclusive in the absence of manifest error.

         (g) Each Reference Bank agrees to use its best efforts to furnish
quotations to the Agent as contemplated by this Section. If any Reference Bank
does not furnish a timely quotation, the Agent shall determine the relevant
interest rate on the basis of the quotation or quotations furnished by the
remaining Reference Bank or Banks or, if none of such quotations is available on
a timely basis, the provisions of Section 8.01 shall apply.

         (h) The "APPLICABLE MARGIN" with respect to any Euro-Dollar Loan or CD
Loan at any date is the applicable percentage amount set forth in the table

         SECTION 2.08. Facility Fee. (a) The Borrower shall pay to the Agent for
the account of the Banks ratably a facility fee at the Facility Fee Rate. Such
facility fee shall accrue (i) from and including the date hereof to but
excluding the Termination Date (or earlier date of termination of the
Commitments in their entirety), on the daily aggregate amount of the Commitments
(whether used or unused) and (ii) from and including the Termination Date (or
earlier date of termination of the Commitments in their entirety) to but
excluding the date the Loans shall be repaid in their entirety, on the daily
aggregate outstanding principal amount of the Loans.

         The "FACILITY FEE RATE" at any date is: (i) 0.075% if Level I Status
exists at such date, (ii) 0.080% if Level II Status exists at such date, (iii)
0.095% if Level III Status exists at such date, (iv) 0.125% if Level IV Status
exists at such date, (v) 0.150% if Level V Status exists at such date or (vi)
0.225% if Level VI Status exists at such date.

          (b) Accrued fees under this Section shall be payable quarterly in
arrears on each Quarterly Payment Date and upon the date of termination of the
Commitments in their entirety (and, if later, the date the Loans shall be repaid
in their entirety).

         SECTION 2.09. Optional Termination or Reduction of Commitments. The
Borrower may, upon at least three Domestic Business Days' notice to the Agent,
(i) terminate the Commitments at any time, if no Loans are outstanding at such
time or (ii) ratably reduce from time to time by an aggregate amount of
$10,000,000 or any larger multiple thereof, the aggregate amount of the
Commitments in excess of the aggregate outstanding principal amount of the
Loans. Promptly after receiving a notice pursuant to this Section, the Agent
shall notify each Bank of the contents thereof.

         SECTION 2.10. Mandatory Termination of Commitments. The Commitments
shall terminate on the Termination Date, and any Loans then outstanding
(together with accrued interest thereon) shall be due and payable on such date.

         SECTION 2.11. Optional Prepayments. (a) The Borrower may (i) upon at
least one Domestic Business Day's notice to the Agent, prepay any Group of Base
Rate Loans (or any Money Market Borrowing bearing interest at the Base Rate
pursuant to Section 8.01(a)), (ii) upon at least three Domestic Business Days'
notice to the Agent, subject to Section 2.13, prepay any Group of CD Loans and
(iii) upon at least three Euro-Dollar Business Days' notice to the Agent,
subject to Section 2.13, prepay any Group of Euro-Dollar Loans, in whole at any
time, or from time to time in part in amounts aggregating $10,000,000 or any
larger multiple of $1,000,000, by paying the principal amount to be prepaid
together with accrued interest thereon to but not including the date of
prepayment. Each such optional prepayment shall be applied to prepay ratably the
Loans of the several Banks included in such Group of Loans (or such Money Market
Borrowing).


                                       26
<PAGE>   32
         (b) Except as provided in Section 2.11(a)(i), the Borrower may not
prepay all or any portion of the principal amount of any Money Market Loan prior
to the maturity thereof.

         (c) Upon receipt of a notice of prepayment pursuant to this Section,
the Agent shall promptly notify each Bank of the contents thereof and of such
Bank's ratable share (if any) of such prepayment and once notice is so given to
the Banks, the Borrower's notice of prepayment shall not thereafter be revocable
by the Borrower.

         SECTION 2.12. General Provisions as to Payments. (a) The Borrower shall
make each payment of principal of, and interest on, the Loans and of fees
hereunder, not later than 2:00 P.M. (New York City time) on the date when due,
in Federal or other funds immediately available in New York City, to the Agent
at its address referred to in Section 9.01. The Agent will promptly distribute
to each Bank its ratable share of each such payment received by the Agent for
the respective accounts of the Banks. Whenever any payment of principal of, or
interest on, the Domestic Loans or of fees shall be due on a day which is not a
Domestic Business Day, the date for payment thereof shall be extended to the
next succeeding Domestic Business Day. Whenever any payment of principal of, or
interest on, the Euro-Dollar Loans shall be due on a day which is not a
Euro-Dollar Business Day, the date for payment thereof shall be extended to the
next succeeding Euro-Dollar Business Day unless such Euro-Dollar Business Day
falls in another calendar month, in which case the date for payment thereof
shall be the next preceding Euro-Dollar Business Day. Whenever any payment of
principal of, or interest on, the Money Market Loans shall be due on a day which
is not a Euro-Dollar Business Day, the date for payment thereof shall be
extended to the next succeeding Euro-Dollar Business Day. If the date for any
payment of principal is extended by operation of law or otherwise, interest
thereon shall be payable for such extended time.

         (b) Unless the Agent shall have received notice from the Borrower prior
to the date on which any payment is due to the Banks hereunder that the Borrower
will not make such payment in full, the Agent may assume that the Borrower has
made such payment in full to the Agent on such date and the Agent may, in
reliance upon such assumption, cause to be distributed to each Bank on such due
date an amount equal to the amount then due such Bank. If and to the extent that
the Borrower shall not have so made such payment, each Bank shall repay to the
Agent forthwith on demand such amount distributed to such Bank together with
interest thereon, for each day from the date such amount is distributed to such
Bank until the date such Bank repays such amount to the Agent, at the Federal
Funds Rate.

         SECTION 2.13. Funding Losses. If the Borrower makes any payment of
principal with respect to any Fixed Rate Loan or any Fixed Rate Loan is
converted to a different type of Loan (pursuant to Article 2, 6 or 8 (other than
Section 8.02)) on any day other than the last day of an Interest Period
applicable thereto, or the last day of an applicable period fixed pursuant to
Section 2.07(d), or if the Borrower fails to borrow, prepay, convert or continue
any Fixed Rate Loans after notice has been given to any Bank in accordance with
Section 2.04(a), 2.11(c) or 2.16 (other than as a result of default by such
Bank), the Borrower shall reimburse each Bank within 15 days after written
demand for any resulting loss or expense reasonably incurred by it


                                       27
<PAGE>   33
(or by an existing or prospective Participant in the related Loan) in obtaining,
liquidating or employing deposits from third parties, but excluding loss of
margin for the period after any such payment or conversion or failure to borrow,
prepay, convert or continue; provided that such Bank shall have delivered to the
Borrower a certificate specifying in reasonable detail the calculation of, and
the reasons for, the amount of such loss or expense, which certificate shall be
conclusive in the absence of manifest error.

         SECTION 2.14. Computation of Interest and Fees. Interest based on the
Prime Rate hereunder shall be computed on the basis of a year of 365 days (or
366 days in a leap year) and paid for the actual number of days elapsed
(including the first day but excluding the last day). All other interest and
fees shall be computed on the basis of a year of 360 days and paid for the
actual number of days elapsed (including the first day but excluding the last
day).

         SECTION 2.15. Regulation D Compensation. Each Bank may require the
Borrower to pay, contemporaneously with each payment of interest on the
Euro-Dollar Loans, additional interest on the related Euro-Dollar Loan of such
Bank at a rate per annum determined by such Bank up to but not exceeding the
excess of (i) (A) the applicable London Interbank Offered Rate divided by (B)
one minus the Euro-Dollar Reserve Percentage over (ii) the applicable London
Interbank Offered Rate. Any Bank wishing to require payment of such additional
interest (x) shall so notify the Borrower and the Agent, in which case such
additional interest on the Euro-Dollar Loans of such Bank shall be payable to
such Bank at the place indicated in such notice with respect to each Interest
Period commencing at least three Euro-Dollar Business Days after the giving of
such notice, and (y) shall notify the Borrower at least five Euro-Dollar
Business Days prior to each date on which interest is payable on the Euro-Dollar
Loans of the amount then due it under this Section.

         "EURO-DOLLAR RESERVE PERCENTAGE" means for any day that percentage
(expressed as a decimal) which is in effect on such day, as prescribed by the
Board of Governors of the Federal Reserve System (or any successor) for
determining the maximum reserve requirement for a member bank of the Federal
Reserve System in New York City with deposits exceeding five billion dollars in
respect of "Eurocurrency liabilities" (or in respect of any other category of
liabilities which includes deposits by reference to which the interest rate on
Euro-Dollar Loans is determined or any category of extensions of credit or other
assets which includes loans by a non-United States office of any Bank to United
States residents).

         SECTION 2.16. Method of Electing Interest Rates. (a) The Loans included
in each Committed Borrowing shall bear interest initially at the type of rate
specified by the Borrower in the applicable Notice of Committed Borrowing.
Thereafter, the Borrower may from time to time elect to change or continue the
type of interest rate borne by each Group of Loans (subject to subsection
2.16(d) of this Section and the provisions of Article 8), as follows:

                  (i) if such Loans are Base Rate Loans, the Borrower may elect
         to convert such Loans to CD Loans as of any Domestic Business Day or to
         Euro-Dollar Loans as of any Euro-Dollar Business Day;


                                       28
<PAGE>   34
                  (ii) if such Loans are CD Loans, the Borrower may elect to
         convert such Loans to Base Rate Loans or Euro-Dollar Loans or elect to
         continue such Loans as CD Loans for an additional Interest Period,
         subject to Section 2.13 if any such conversion is effective on any day
         other than the last day of an Interest Period applicable to such Loans;
         and

                  (iii) if such Loans are Euro-Dollar Loans, the Borrower may
         elect to convert such Loans to Base Rate Loans or CD Loans or elect to
         continue such Loans as Euro-Dollar Loans for an additional Interest
         Period, subject to Section 2.13 if any such conversion is effective on
         any day other than the last day of an Interest Period applicable to
         such Loans.

Each such election shall be made by delivering a notice (a "Notice of Interest
Rate Election") to the Agent not later than 10:30 A.M. (New York City time) on
the third Euro-Dollar Business Day before the conversion or continuation
selected in such notice is to be effective (unless the relevant Loans are to be
converted from Domestic Loans of one type to Domestic Loans of the other type or
are CD Loans to be continued as CD Loans for an additional Interest Period, in
which case such notice shall be delivered to the Agent not later than 10:30 A.M.
(New York City time) on the second Domestic Business Day before such conversion
or continuation is to be effective). A Notice of Interest Rate Election may, if
it so specifies, apply to only a portion of the aggregate principal amount of
the relevant Group of Loans; provided that (i) such portion is allocated ratably
among the Loans comprising such Group and (ii) the portion to which such Notice
applies, and the remaining portion to which it does not apply, are each at least
$10,000,000 (unless such portion is comprised of Base Rate Loans). If no such
notice is timely received before the end of an Interest Period for any Group of
CD Loans or Euro-Dollar Loans, the Borrower shall be deemed to have elected that
such Group of Loans be converted to Base Rate Loans at the end of such Interest
Period.

         (b) Each Notice of Interest Rate Election shall specify:

                  (i) the Group of Loans (or portion thereof) to which such
         notice applies;

                  (ii) the date on which the conversion or continuation selected
         in such notice is to be effective, which shall comply with the
         applicable clause of subsection 2.16(a) above;

                  (iii) if the Loans comprising such Group are to be converted,
         the new type of Loans and, if the Loans resulting from such conversion
         are to be CD Loans or Euro- Dollar Loans, the duration of the next
         succeeding Interest Period applicable thereto; and

                  (iv) if such Loans are to be continued as CD Loans or
         Euro-Dollar Loans for an additional Interest Period, the duration of
         such additional Interest Period.


                                       29
<PAGE>   35
Each Interest Period specified in a Notice of Interest Rate Election shall
comply with the provisions of the definition of Interest Period.

          (c) Promptly after receiving a Notice of Interest Rate Election from
the Borrower pursuant to subsection (a) above, the Agent shall notify each Bank
of the contents thereof and such notice shall not thereafter be revocable by the
Borrower.

          (d) The Borrower shall not be entitled to elect to convert any
Committed Loans to, or continue any Committed Loans for an additional Interest
Period as, CD Loans or Euro-Dollar Loans if (i) the aggregate principal amounts
of any Group of CD Loans or Euro-Dollar Loans created or continued as a result
of such election would be less than $10,000,000 or (ii) a Default shall have
occurred and be continuing when the Borrower delivers notice of such election to
the Agent.

                         REPRESENTATIONS AND WARRANTIES

                  The Borrower represents and warrants to the Agent and the
Banks that:

         SECTION 4.01. Corporate Existence and Power. The Borrower is a
corporation (in the case of Tyco US) or a company (in the case of Tyco
Luxembourg) duly incorporated and validly existing and (in the case of Tyco US)
in good standing under the laws of its jurisdiction of incorporation. The
Borrower has all corporate powers and all governmental licenses, authorizations,
consents and approvals (collectively, the "Consents") required to carry on its
business as now conducted, other than those powers and Consents, the failure of
which to be possessed or obtained could not, based upon the facts and
circumstances in existence at the time this representation and warranty is made
or deemed made, reasonably be expected to have a Material Adverse Effect.

         SECTION 4.02. Corporate and Governmental Authorization; No
Contravention. The execution, delivery and performance by the Borrower of this
Agreement and the Promissory Notes: (a) are within the Borrower's corporate
powers; (b) have been duly authorized by all necessary corporate action on the
part of the Borrower; (c) require no action by or in respect of, or filing with,
any governmental body, agency or official, in each case, on the part of the
Borrower; and (d) do not contravene, or constitute a default by the Borrower
under, any provision of (i) applicable law or regulation, (ii) the
organizational documents of the Borrower, or (iii) any agreement or instrument
evidencing or governing Debt of the Borrower or any other material agreement,
judgment, injunction, order, decree or other instrument binding upon the
Borrower.

         SECTION 4.03. Binding Effect. This Agreement constitutes a valid and
binding agreement of the Borrower and the Promissory Notes, when executed and
delivered in accordance with this Agreement, will constitute valid and binding
obligations of the Borrower.

         SECTION 4.04.  Financial Information.

          (a) The consolidated balance sheet of the Borrower and its
Consolidated Subsidiaries as of June 30, 1997 and the related consolidated
statements of income, of shareholders' equity and of cash flows for the fiscal
year then ended, reported on by Coopers & Lybrand L.L.P., copies of which have
been delivered to each of the Banks, fairly present, in conformity with
generally accepted accounting principles, the consolidated financial position of
the Borrower and




                                       36
<PAGE>   42
its Consolidated Subsidiaries as of such date and their consolidated results of
operations and cash flows for such fiscal year.

          (b) Since June 30, 1997 there has been no material adverse change in
the business, financial position, results of operations or Prospects of the
Borrower and its Consolidated Subsidiaries, considered as a whole.

         SECTION 4.05. Litigation. There is no action, suit or proceeding
pending against, or to the knowledge of the Borrower threatened against or
affecting, the Borrower or any of its Subsidiaries before any court or
arbitrator or any governmental body, agency or official in which there is a
reasonable possibility of an adverse decision which could, based upon the facts
and circumstances in existence at the time this representation and warranty is
made or deemed made, reasonably be expected to have a Material Adverse Effect or
which in any manner draws into question the validity of the Financing Documents.

         SECTION 4.06. Compliance with ERISA. Each member of the ERISA Group has
fulfilled its obligations under the minimum funding standards of ERISA and the
Internal Revenue Code with respect to each Plan and is in compliance, except
where the failure to so comply could not, based upon the facts and circumstances
in existence at the time this representation and warranty is made or deemed
made, reasonably be expected to have a Material Adverse Effect, with the
presently applicable provisions of ERISA and the Internal Revenue Code with
respect to each Plan. No member of the ERISA Group has (i) sought a waiver of
the minimum funding standard under Section 412 of the Internal Revenue Code in
respect of any Plan, (ii) failed to make any required contribution or payment to
any Plan or Multiemployer Plan, or made any amendment to any Plan, which has
resulted in or could, based upon the facts and circumstances in existence at the
time this representation and warranty is made or deemed made, reasonably be
expected to result in the imposition of a Lien or the posting of a bond or other
security under ERISA or the Internal Revenue Code or (iii) incurred any
liability under Title IV of ERISA (other than a liability to the PBGC for
premiums under Section 4007 of ERISA), which could, based upon the facts and
circumstances existing at the time this representation and warranty is made or
deemed made, reasonably be expected to have a Material Adverse Effect.

         SECTION 4.07. Environmental Matters. In the ordinary course of its
business, the Borrower conducts an ongoing review of the effect of Environmental
Laws on the business, operations and properties of the Borrower and its
Subsidiaries, in the course of which it identifies and evaluates associated
liabilities and costs (including, without limitation, any capital or operating
expenditures required for clean-up or closure of properties presently or
previously owned, any capital or operating expenditures required to achieve or
maintain compliance with environmental protection standards imposed by law or as
a condition of any license, permit or contract, any related constraints on
operating activities, including any periodic or permanent shutdown of any
facility or reduction in the level of or change in the nature of operations
conducted thereat, any costs or liabilities in connection with off-site disposal
of wastes or Hazardous Substances, and any actual or potential liabilities to
third parties, including employees, and any related costs and expenses). On the
basis of this review, the Borrower has



                                       37
<PAGE>   43
reasonably concluded that such associated liabilities and costs, including the
costs of compliance with Environmental Laws, could not, based upon the facts and
circumstances existing at the time this representation and warranty is made or
deemed made, reasonably be expected to have a Material Adverse Effect.

         SECTION 4.08. Taxes. The Borrower and its Subsidiaries have filed all
United States Federal income tax returns and all other material tax returns
which are required to be filed by them and have paid all taxes shown on such
returns or pursuant to any assessment received by the Borrower or any
Subsidiary, except those assessments which are being contested in good faith by
appropriate proceedings. The charges, accruals and reserves on the books of the
Borrower and its Subsidiaries in respect of taxes or other governmental charges
are, in the opinion of the Borrower, adequate.

         SECTION 4.09. Subsidiaries. Each of the Borrower's corporate
Consolidated Subsidiaries is a corporation duly incorporated, validly existing
and in good standing under the laws of its jurisdiction of incorporation, except
where the failure to be so incorporated, existing or in good standing could not,
based upon the facts and circumstances existing at the time this representation
and warranty is made or deemed made, reasonably be expected to have a Material
Adverse Effect. Each such Subsidiary has all corporate powers and all Consents
required to carry on its business as now conducted, other than those powers and
Consents, the failure of which to be possessed or obtained could not, based upon
the facts and circumstances in existence at the time this representation and
warranty is made or deemed made, reasonably be expected to have a Material
Adverse Effect.

         SECTION 4.10. Not an Investment Company. The Borrower is not an
"investment company" within the meaning of the Investment Company Act of 1940,
as amended.

         SECTION 4.11. Full Disclosure. The factual information, reports,
financial statements, exhibits and schedules concerning the Borrower and its
Subsidiaries furnished by or on behalf of the Borrower and contained in the
Confidential Information Memorandum dated January 1998 furnished by J.P. Morgan
Securities Inc. to a limited number of banks which were being invited to
participate in this Agreement, do not contain any untrue statement of material
fact or omit to state any material fact necessary to make the statements
contained herein or therein, in light of the circumstances under which they were
made, not misleading.


                                    ARTICLE 5

                                    COVENANTS

respective representatives or agents) or any Recipient, which source, to the
knowledge of the Recipient, is not prohibited from disclosing such information
by a confidentiality agreement with, or other legal or fiduciary obligation to,
the Borrower or its Subsidiaries.

         The restrictions set forth in the immediately preceding paragraph shall
not prevent the disclosure by a Recipient of any such information:

                  of competent jurisdiction, to the extent required by such
                  order and not effectively stayed on appeal or otherwise, or as

                  Borrower not less than five Domestic Business Days prior
                  notice (or such shorter period as may, in the good faith
                  discretion of the Recipient, be reasonable under the
                  circumstances or may be required by any court or agency under
                  the circumstances), specifying the Confidential Information
                  involved and stating such Recipient's intention to disclose
                  such Confidential Information (including the manner and extent
                  of such disclosure) in order to allow the Borrower an
                  opportunity to seek an appropriate protective order.

         Each Recipient shall agree that, in addition to all other remedies
available, the Borrower shall be entitled to specific performance and injunctive

such Recipient.

         SECTION 5.07. Limitation on Restrictions on Subsidiary Dividends and
Other Distributions. The Borrower will not, and will not permit any Subsidiary
to, directly or indirectly, create or otherwise cause or suffer to exist or
become effective any encumbrance or

         (a) any Lien existing on any asset on the Effective Date securing Debt
outstanding on the Effective Date;

         (b) any Lien existing on any asset of, or capital stock of, or other

property, whichever is later), which Debt is incurred or assumed for the purpose
of financing all or part of the cost of acquiring such asset or, in the case of

partial, progress, advance or other payments pursuant to any contract, statute,
rule or regulation or securing obligations incurred for the purpose of financing
all or any part of the purchase price (including the cost of installation
thereof or, in the case of real property, the cost of construction or
improvement or installation of



                                       46

business; and

asset and, with respect to Liens permitted pursuant to subsections (a), (b),
(d), (e), (f) (but only with respect to the Refinancing of a Debt secured by a
Lien permitted pursuant to subsections (a), (b), (d) or (e)) or (g) of this
Section 5.10, may attach to an asset acquired in the ordinary course of business
as a replacement of such former asset.

Borrower will not (i) consolidate or merge with or into any other Person or (ii)
sell, lease or otherwise transfer all or substantially all of its assets to any

                  leases, all or substantially all of the assets of the Borrower
                  (any such Person, the "Successor"), shall be organized and

                  United States, any state thereof or the District of Columbia

                  expressly assume, in a writing executed and delivered to the
                  Agent for delivery to each of the Banks, in form reasonably
                  satisfactory to the Agent, the due and punctual payment of the
                  principal of and interest on the Promissory Notes and the
                  performance of the other obligations under this Agreement and
                  the Promissory Notes on the part of the Borrower to be
                  performed or observed, as fully as if such Successor were
                  originally named as the Borrower in this Agreement;

                           (C) immediately after giving effect to such
                  transaction, no Default shall have occurred and be continuing;

<PAGE>   53

                  certificate on behalf of the Borrower signed by a Responsible
                  Officer and an opinion of counsel (which counsel may be an
                  employee of the Borrower), each stating that all conditions
                  provided in this Section 5.11 relating to such transaction
                  have been satisfied.

         The foregoing provisions of this Section 5.11 shall not restrict the
merger or consolidation of any Subsidiary with and into the Borrower.

         Upon the satisfaction (or waiver in accordance with Section 9.05) of
the conditions set forth in this Section 5.11, the Successor shall succeed, and
may exercise every right and power of, the Borrower under this Agreement and the
Promissory Notes with the same effect as if the Successor had been originally
named as the Borrower herein and in the Promissory Notes, and the Borrower shall
be relieved of its obligations under this Agreement and the Promissory Notes.

         (b) The Borrower will not, and will not permit any Subsidiary to, sell,
lease or otherwise transfer, in any transaction or series of related
transactions, to any Person (other than the Borrower, a Subsidiary, a Person of
which the Borrower is a Subsidiary or a Subsidiary of such a Person) any
Property (including, without limitation, the stock of any Subsidiary) having a
net book value in excess of 15% of Consolidated Assets determined as of the end
of the fiscal quarter of the Borrower most recently ended at the time of such

or indirectly, for the purpose, whether immediate, incidental or ultimate, of
buying or carrying any "margin stock" within the meaning of Regulation U.

         SECTION 5.13. Transactions with Affiliates. The Borrower will not, and
will not permit any Subsidiary to, directly or indirectly, pay any funds to or
for the account of, make any investment (whether by acquisition of stock or
indebtedness, by loan, advance, transfer of property, guarantee or other
agreement to pay, purchase or service, directly or indirectly, any Debt, or
otherwise) in, lease, sell, transfer or otherwise dispose of any assets,
tangible or intangible, to, or participate in, or effect any transaction in
connection with any joint enterprise or other joint arrangement with, any
Affiliate (collectively, "AFFILIATE TRANSACTIONS"); provided, however, that the
foregoing provisions of this Section 5.13 shall not prohibit the Borrower or any
of its Subsidiaries from: (a) making sales to or purchases from any Affiliate
and, in connection therewith, extending credit or making payments, or from
making payments for services rendered by any Affiliate, if such sales or
purchases are made or such services are rendered in the ordinary course of
business and on terms and conditions at least as favorable to the Borrower or
such Subsidiary as the terms and conditions which the Borrower would reasonably
expect to be obtained in a similar transaction with a Person which is not an
Affiliate at such time, (b) making


                                       48

<PAGE>   54

Subsidiary held by an Affiliate if the terms of such Debt are at least as
favorable to the Borrower or such Subsidiary as the terms which the Borrower
would reasonably expect to have been obtained at the time of the creation of
such Debt from a lender which was not an Affiliate, (c) participating in, or
effecting any transaction in connection with, any joint enterprise or other
joint arrangement with any Affiliate if the Borrower or such Subsidiary
participates in the ordinary course of its business and on a basis no less
advantageous than the basis on which such Affiliate participates, (d) paying or
granting reasonable compensation and benefits to any director, officer, employee
or agent of the Borrower or any Subsidiary, (e) paying reasonable legal fees and
expenses to a law firm of which an Affiliate is a member or (f) engaging in any

New Borrower Date, any Person shall become a Required Significant Subsidiary of
the Borrower, the Borrower shall cause such Person to become a Subsidiary

satisfaction of any condition specified in Article 3, except receipt of items
required to be delivered to the Agent; or (iv) the validity, effectiveness or
genuineness of this Agreement, the Subsidiary Guarantees, the Parent Guarantee,
the Promissory Notes or any other instrument or writing furnished in connection
herewith. The Agent shall not incur any liability by acting in reliance upon any
notice, consent, certificate, statement, or other writing (which may be a bank
wire, telex or similar writing) believed by it in good faith to be genuine or to
be signed by or on behalf of the proper party or parties. Without limiting the
generality of the foregoing, the use of the term "agent" in this Agreement with
reference to the Agent is not intended to connote any fiduciary or other implied
(or express) obligations arising under agency doctrine of any


                                       52

<PAGE>   58
applicable law. Instead, such term is used merely as a matter of market custom
and is intended to create or reflect only an administrative relationship between
independent contracting parties.

         SECTION 7.06. Indemnification. Each Bank shall, ratably in accordance
with its Commitment, indemnify the Agent, its affiliates and their respective
directors, officers, agents and employees (to the extent not reimbursed by the
Borrower) against any cost, expense (including counsel fees and disbursements),
claim, demand, action, loss or liability (except such as result from such
indemnitees' gross negligence or willful misconduct) that such indemnitees may
suffer or incur in connection with the Financing Documents or any action taken
or omitted by such indemnitees thereunder.

         SECTION 7.07. Credit Decision. Each Bank acknowledges that it has,
independently and without reliance upon the Agent or any other Bank, and based
on such documents and information as it has deemed appropriate, made its own
credit analysis of the Borrower and its Subsidiaries and its own decision to
enter into this Agreement. Each Bank also acknowledges that it will,
independently and without reliance upon the Agent or any other Bank, and based
on such documents and information as it shall deem appropriate at the time,
continue to make its own credit decisions in taking or not taking any action
under this Agreement.

         SECTION 7.08. Successor Agent. The Agent may resign at any time by
giving notice thereof to the Banks and the Borrower. Upon any such resignation,
the Required Banks shall have the right to appoint a successor Agent, subject to
the consent of the Borrower. If no successor Agent shall have been so appointed
by the Required Banks and consented to by the Borrower and shall have accepted
such appointment within 45 days after the retiring Agent gives notice of
resignation, then the retiring Agent may, on behalf of the Banks, appoint a
successor Agent, which shall be a commercial bank organized or licensed under
the laws of the United States of America or of any State thereof and having a
combined capital and surplus of at least $50,000,000. Upon the acceptance of its
appointment as Agent hereunder by a successor Agent, such successor Agent shall
thereupon succeed to and become vested with all the rights, powers, privileges
and duties of the retiring Agent, and the retiring Agent shall be discharged
from its duties and obligations under the Financing Documents. After any
retiring Agent's resignation hereunder as Agent, the provisions of this Article
shall inure to its benefit as to any actions taken or omitted to be taken by it
while it was acting as the Agent.

         SECTION 7.09. Agent's Fee. The Borrower shall pay to the Agent for its
own account fees in the amounts and at the times previously agreed upon in
writing between the Borrower and the Agent.

                                    ARTICLE 8

                             CHANGE IN CIRCUMSTANCES

         SECTION 8.01. Basis for Determining Interest Rate Inadequate or Unfair.
If on or prior to the first day of any Interest Period for any CD Loan,
Euro-Dollar Loan or Money Market LIBOR Loan:

         (a) the Agent is advised by the Reference Banks that deposits in
dollars (in the applicable amounts) are not being offered to the Reference Banks
in the relevant market for such Interest Period, or

         (b) in the case of CD Loans or Euro-Dollar Loans, Banks holding 50% or
more of the aggregate amount of the affected Loans advise the Agent that the
Adjusted CD Rate or the London Interbank Offered Rate, as the case may be, as
determined by the Agent will not adequately and fairly reflect the cost to such
Banks of funding their CD Loans or Euro-Dollar Loans, as the case may be, for
such Interest Period,

the Agent shall forthwith give notice thereof to the Borrower and the Banks,
whereupon, until the Agent notifies the Borrower that the circumstances giving
rise to such suspension no longer exist (which the Agent agrees to do promptly
upon such circumstances ceasing to exist), (i) the obligations of the Banks to
make CD Loans or Euro-Dollar Loans, as the case may be, or to continue or
convert outstanding Loans as or into CD Loans or Euro-Dollar Loans, as the case
may be, shall be suspended and (ii) each outstanding CD Loan or Euro-Dollar
Loan, as the case may be, shall be converted into a Base Rate Loan on the last
day of the then current Interest Period applicable thereto. Unless the Borrower
notifies the Agent at least one Domestic Business Day before the date of any
Fixed Rate Borrowing for which a Notice of Borrowing has previously been given
that it elects not to borrow on such date, (i) if such Fixed Rate Borrowing is a
Committed Borrowing, such Borrowing shall instead be made as a Base Rate
Borrowing and (ii) if such Fixed Rate Borrowing is a Money Market LIBOR
Borrowing, the Money Market LIBOR Loans comprising such Borrowing shall bear
interest for each day from and including the first day to but excluding the last
day of the Interest Period applicable thereto at the Base Rate for such day.

         SECTION 8.02. Illegality. If, on or after the date of this Agreement,
any Bank has determined in its reasonable judgment that the adoption of any
applicable law, rule or regulation, or any change in any applicable law, rule or
regulation, or any change in the interpretation or administration thereof by any
governmental authority, central bank or comparable agency charged with the
interpretation or administration thereof, or compliance by any Bank (or its
Euro-Dollar Lending Office) with any request or directive (whether or not having
the force of law) of any such authority, central bank or comparable agency,
shall make it unlawful or impossible for such Bank (or its Euro-Dollar Lending
Office) to make, maintain or fund its Euro-Dollar Loans and such Bank shall so
notify the Agent, the Agent shall forthwith give notice specifying the
circumstances giving rise to such suspension to the other Banks and the
Borrower, whereupon, until such Bank notifies the Borrower and the Agent that
the circumstances giving 


                                       54

<PAGE>   60
rise to such suspension no longer exist (which such Bank agrees to do promptly
upon such circumstances ceasing to exist), the obligation of such Bank to make
Euro-Dollar Loans, or to continue or convert outstanding Loans as or into
Euro-Dollar Loans, shall be suspended. Before giving any notice to the Agent
pursuant to this Section, such Bank shall designate a different Euro-Dollar
Lending Office if such designation will avoid the need for giving such notice
and will not, in the judgment of such Bank in the good faith exercise of its
discretion, be otherwise disadvantageous to such Bank. If such notice is given,
each Euro-Dollar Loan of such Bank then outstanding shall be converted to a Base
Rate Loan either (a) on the last day of the then current Interest Period
applicable to such Euro-Dollar Loan if such Bank may lawfully continue to
maintain and fund such Loan as a Euro-Dollar Loan to such day or (b) immediately
if such Bank shall determine that it may not lawfully continue to maintain and
fund such Loan as a Euro-Dollar Loan to such day.

         SECTION 8.03. Increased Cost and Reduced Return. (a) If on or after (x)
the date of this Agreement, in the case of any Committed Loan or any obligation
to make Committed Loans or (y) the date of the related Money Market Quote, in
the case of any Money Market Loan, any Bank has determined in its reasonable
judgment that the adoption of any applicable law, rule or regulation, or any
change in any applicable law, rule or regulation, or any change in the
interpretation or administration thereof by any governmental authority, central
bank or comparable agency charged with the interpretation or administration
thereof, or compliance by any Bank (or its Applicable Lending Office) with any
request or directive (whether or not having the force of law) of any such
authority, central bank or comparable agency, shall impose, modify or deem
applicable any reserve (including, without limitation, any such requirement
imposed by the Board of Governors of the Federal Reserve System, but excluding
(i) with respect to any CD Loan any such requirement included in an applicable
Domestic Reserve Percentage and (ii) with respect to any Euro-Dollar Loan any
such requirement with respect to which such Bank is entitled to compensation
during the relevant Interest Period under Section 2.15), special deposit,
insurance assessment (excluding, with respect to any CD Loan, any such
requirement reflected in an applicable Assessment Rate) or similar requirement
against assets of, deposits with or for the account of, or credit extended by,
such Bank (or its Applicable Lending Office) or shall impose on any Bank (or its
Applicable Lending Office) or on the United States market for certificates of
deposit or the London interbank market any other condition affecting its Fixed
Rate Loans, its Promissory Note or its obligation to make Fixed Rate Loans and
the result of any of the foregoing is to increase the cost to such Bank (or its
Applicable Lending Office) of making or maintaining any Fixed Rate Loan, or to
reduce the amount of any sum received or receivable by such Bank (or its
Applicable Lending Office) under this Agreement or under its Promissory Note
with respect thereto, by an amount deemed by such Bank to be material to such
Bank, then, within 15 days after written demand by such Bank (with a copy to the
Agent), the Borrower shall pay to such Bank such additional amount or amounts as
will compensate such Bank for such increased cost or reduction.

         (b) If any Bank shall have determined that, after the date of this
Agreement, the adoption of any applicable law, rule or regulation regarding
capital adequacy, or any change in any such law, rule or regulation, or any
change in the interpretation or administration thereof by


                                       55

<PAGE>   61
any governmental authority, central bank or comparable agency charged with the
interpretation or administration thereof, or any request or directive regarding
capital adequacy (whether or not having the force of law) of any such authority,
central bank or comparable agency, has or would have the effect of reducing the
rate of return on capital of such Bank (or its Parent) as a consequence of such
Bank's obligations hereunder to a level below that which such Bank (or its
Parent) could have achieved but for such adoption, change, request or directive
(taking into consideration its policies with respect to capital adequacy) by an
amount deemed by such Bank to be material, then from time to time, within 15
days after written demand by such Bank (with a copy to the Agent), the Borrower
shall pay to such Bank such additional amount or amounts as will compensate such
Bank (or its Parent) for such reduction.

         (c) Each Bank will promptly notify the Borrower and the Agent of any
event of which it has knowledge, occurring after the date of this Agreement,
which will entitle such Bank to compensation pursuant to this Section; provided
that (i) if any Bank fails to give such notice within 90 days after it obtains
actual knowledge of such an event, such Bank shall only be entitled to payment
under this Section 8.03 for costs incurred from and after the date 90 days prior
to the date that such Bank does give such notice and (ii) each such Bank will
designate a different Applicable Lending Office if such designation will avoid
the need for, or reduce the amount of, such compensation and will not, in the
judgment of such Bank in the good faith exercise of its discretion, be otherwise
disadvantageous to such Bank. A certificate of any Bank claiming compensation
under this Section and setting forth in reasonable detail the additional amount
or amounts to be paid to it hereunder and the basis used to determine such
amounts shall be conclusive in the absence of manifest error. In determining
such amount, such Bank will use reasonable averaging and attribution methods and
will have a reasonable basis for any assumptions it makes in connection
therewith.

         SECTION 8.04. Taxes. (a) Any and all payments by the Borrower to or for
the account of any Bank or the Agent hereunder or under any Promissory Note
shall be made free and clear of and without deduction for any and all present or
future taxes, duties, levies, imposts, deductions, charges or withholdings, and
all liabilities with respect thereto, excluding, in the case of each Bank and
the Agent, taxes imposed on or measured by its income, and franchise taxes
imposed on it, by the jurisdiction under the laws of which such Bank or the
Agent (as the case may be) is organized or any political subdivision thereof
and, in the case of each Bank, taxes imposed on or measured by its income, and
franchise or similar taxes imposed on it, by the jurisdiction of such Bank's
Applicable Lending Office or any political subdivision thereof (all such
non-excluded taxes, duties, levies, imposts, deductions, charges, withholdings
and liabilities being hereinafter referred to as its "TAXES", and all such
excluded taxes being hereinafter referred to as its "DOMESTIC TAXES"). If the
Borrower shall be required by law to deduct any Taxes from or in respect of any
sum payable hereunder or under any Promissory Note to any Bank or the Agent, (i)
the sum payable shall be increased as necessary so that after making all
required deductions (including deductions applicable to additional sums payable
under this Section 8.04 such Bank or the Agent (as the case may be) receives an
amount equal to the sum it would have received had no such deductions been made,
(ii) the Borrower shall make such deductions, (iii) the Borrower shall pay the
full amount deducted to the relevant taxation authority or other authority in


                                       56

<PAGE>   62
accordance with applicable law and (iv) the Borrower shall furnish to the Agent,
at its address referred to in Section 9.01, the original or a certified copy of
a receipt evidencing payment thereof.

         (b) In addition, the Borrower agrees to pay any present or future stamp
or documentary taxes and any other excise or property taxes, or charges or
similar levies which arise from any payment made hereunder or under any
Promissory Note or from the execution or delivery of, or otherwise with respect
to, this Agreement or any other Financing Document (hereinafter referred to as
"OTHER TAXES").

         (c) The Borrower agrees to indemnify each Bank and the Agent for the
full amount of Taxes or Other Taxes (including, without limitation, any Taxes or
Other Taxes imposed or asserted by any jurisdiction on amounts payable under
this Section 8.04 paid by such Bank or the Agent (as the case may be) and any
liability (including penalties, interest and expenses) arising therefrom or with
respect thereto. In addition, on and after the New Borrower Date, the Borrower
agrees to indemnify the Agent and each Bank for all Domestic Taxes and any
liability (including penalties, interest and expenses) arising therefrom or with
respect thereto, in each case to the extent that such Domestic Taxes result from
any payment or indemnification pursuant to this Section for (i) Taxes or Other
Taxes imposed by any jurisdiction other than the United States or (ii) Domestic
Taxes of the Agent or such Bank, as the case may be. This indemnification shall
be made within 15 days from the date such Bank or the Agent (as the case may be)
makes demand therefor.

         (d) At the times indicated herein, each Bank organized under the laws
of a jurisdiction outside the United States shall provide the Borrower with
Internal Revenue Service form 1001 or 4224 (in each case accompanied by any
statements which may be required under applicable Treasury regulations), as
appropriate, or any successor form prescribed by the Internal Revenue Service,
certifying that such Bank is entitled to receive payments under this Agreement
(i) without deduction or withholding of any United States federal income taxes
or (ii) subject to a reduced rate of United States federal withholding tax,
unless, in each case of clause (i) and (ii) of this Section 8.04(d), an event
(including, without limitation, any change in treaty, law or regulation) has
occurred prior to the date on which any such delivery would otherwise be
required which renders such forms inapplicable or which would prevent the Bank
from duly completing and delivering any such form with respect to it and the
Bank advises the Borrower and the Agent that it is not capable of receiving
payments without any deduction or withholding of such taxes. Such forms shall be
provided (x) on or prior to the date of the Bank's execution and delivery of
this Agreement in the case of each Bank listed on the signature pages hereof,
and on or prior to the date on which it becomes a Bank in the case of each other
Bank, and (y) on or before the date that such form expires or becomes obsolete
or after the occurrence of any event requiring a change in the most recent form
so delivered by the Bank. If the form provided by a Bank at the time such Bank
first becomes a party to this Agreement indicates a United States interest
withholding tax rate in excess of zero, United States withholding tax at such
rate shall be considered excluded from "TAXES" as defined in Section 8.04(a). In
addition, to the extent that for reasons other than a change of treaty, law or
regulation any Bank becomes subject to an


                                       57

<PAGE>   63
increased rate of United States interest withholding tax while it is a party to
this Agreement, United States withholding tax at such increased rate shall be
considered excluded from "Taxes" as defined in Section 8.04(a).

         (e) For any period with respect to which a Bank has failed to provide
the Borrower with the appropriate form in accordance with Section 8.04(d)
(unless such failure is excused by the terms of Section 8.04(d)), such Bank
shall not be entitled to indemnification under Section 8.04(a) or 8.04(c) with
respect to Taxes imposed by the United States; provided, however, that should a
Bank, which is otherwise exempt from or subject to a reduced rate of withholding
tax, become subject to Taxes because of its failure to deliver a form required
hereunder, the Borrower shall take such steps as such Bank shall reasonably
request to assist such Bank to recover such Taxes.

         (f) If the Borrower is required to pay additional amounts to or for the
account of any Bank pursuant to this Section 8.04, then such Bank will change
the jurisdiction of its Applicable Lending Office so as to eliminate or reduce
any such additional payment which may thereafter accrue if such change, in the
judgment of such Bank in the good faith exercise of its discretion, is not
otherwise disadvantageous to such Bank.

         SECTION 8.05. Base Rate Loans Substituted for Affected Fixed Rate
Loans. If (i) the obligation of any Bank to make, or to continue or convert
outstanding Loans as or to Euro-Dollar Loans has been suspended pursuant to
Section 8.02 or (ii) any Bank has demanded compensation under Section 8.03 or
8.04 with respect to its CD Loans or Euro-Dollar Loans and the Borrower shall,
by at least five Euro-Dollar Business Days' prior notice to such Bank through
the Agent, have elected that the provisions of this Section shall apply to such
Bank, then, unless and until such Bank notifies the Borrower that the
circumstances giving rise to such suspension or demand for compensation no
longer exist (which such Bank agrees to do promptly upon such circumstances
ceasing to exist), all Loans which would otherwise be made by such Bank as (or
continued as or converted to) CD Loans or Euro-Dollar Loans, as the case may be,
shall instead be Base Rate Loans (on which interest and principal shall be
payable contemporaneously with the related Fixed Rate Loans of the other Banks).
If such Bank notifies such Borrower that the circumstances giving rise to such
suspension or demand for compensation no longer exist, the principal amount of
each such Base Rate Loan shall be converted into a CD Loan or Euro-Dollar Loan,
as the case may be, on the first day of the next succeeding Interest Period
applicable to the related CD Loans or Euro-Dollar Loans of the other Banks.

         SECTION 8.06. Substitution of Bank. If any Bank (i) has demanded
compensation for increased costs pursuant to Section 8.03 or 8.04 or is entitled
to payments under Section 8.04(a) or (ii) has determined that the making or
maintaining of any Euro-Dollar Loan has become unlawful or impossible pursuant
to Section 8.02 and similar additional interest or compensation has not been
demanded by, or a similar determination has not been made by, all of the Banks,
the Borrower shall have the right (with the assistance of the Agent) to
designate an Assignee which is not an Affiliate of the Borrower to purchase for
cash, pursuant to an Assignment and Assumption Agreement in substantially the
form of Exhibit G hereto, the outstanding Loans and


                                       58

<PAGE>   64
Commitment of such Bank and to assume all of such Bank's other rights and
obligations hereunder without recourse to or warranty by, or expense to, such
Bank, for a purchase price equal to the principal amount of all of such Bank's
outstanding Loans plus any accrued but unpaid interest thereon and the accrued
but unpaid fees in respect of that Bank's Commitment hereunder plus such amount,
if any, as would be payable pursuant to Section 2.13 if the outstanding Loans of
such Bank were prepaid in their entirety on the date of consummation of such
assignment.


                                    ARTICLE 9

                                  MISCELLANEOUS

         SECTION 9.01. Notices. All notices, requests and other communications
to any party provided for hereunder shall be in writing (including, without
limitation, bank wire, telex, facsimile transmission or similar writing) and
shall be given to such party: (x) in the case of the Borrower or the Agent, at
its address or facsimile or telex number set forth on the signature pages
hereof, (y) in the case of any Bank, at its address or facsimile or telex number
set forth in its Administrative Questionnaire or (z) in the case of any party,
such other address or facsimile or telex number as such party may hereafter
specify for the purpose by notice to the Agent and the Borrower. Each such
notice, request or other communication shall be effective (i) if given by telex,
when such telex is transmitted to the telex number specified in this Section and
the appropriate answerback is received, (ii) if given by facsimile, when such
facsimile is transmitted to the facsimile number specified in this Section 9.01
and electronic, telephonic or other appropriate confirmation of receipt is
received by the sender, (iii) if given by mail, 72 hours after such
communication is deposited in the mails with first class postage prepaid,
addressed as aforesaid or (iv) if given by any other means, when delivered at
the address specified in this Section; provided that notices to the Agent under
Article 2 or Article 8 shall not be effective until received.

         SECTION 9.02. No Waivers. No failure or delay by the Agent or any Bank
in exercising any right, power or privilege hereunder or under any other
Financing Document shall operate as a waiver thereof nor shall any single or
partial exercise thereof preclude any other or further exercise thereof or the
exercise of any other right, power or privilege. The rights and remedies herein
and therein provided shall be cumulative and not exclusive of any rights or
remedies provided by law.

         SECTION 9.03. Expenses; Indemnification. (a) The Borrower shall pay (i)
all reasonable out-of-pocket expenses of the Agent, including reasonable fees
and disbursements of special counsel for the Agent, in connection with the
preparation and administration of the Financing Documents, any waiver or consent
hereunder or any amendment thereof or any Default or alleged Default hereunder
and (ii) if an Event of Default occurs, all reasonable out-of-pocket expenses
incurred by the Agent and each Bank, including reasonable fees and disbursements
of


                                       59

<PAGE>   65
counsel, in connection with such Event of Default and collection, bankruptcy,
insolvency and other enforcement proceedings resulting therefrom.

         (b) The Borrower agrees to indemnify the Agent and each Bank, their
respective Bank Affiliates and the respective directors, officers, agents and
employees of the foregoing (each an "Indemnitee") and hold each Indemnitee
harmless from and against any and all liabilities, losses, damages, costs and
expenses, including, without limitation, the reasonable fees and disbursements
of counsel, which may be incurred by such Indemnitee (whether or not such
Indemnitee shall be designated a party thereto) arising out of any
investigative, administrative or judicial proceeding (brought or threatened)
relating to or arising out of the Financing Documents, the arrangement,
administration, performance or enforcement thereof or any actual or proposed use
of proceeds of Loans hereunder; provided that no Indemnitee shall have the right
to be indemnified hereunder for such Indemnitee's own gross negligence or
willful misconduct as determined by a court of competent jurisdiction; provided
further that no Indemnitee shall have the right to be indemnified hereunder in
connection with any proceedings between it and another Indemnitee which does not
relate to the Borrower.

         (c) If any proceeding or claim shall be brought or asserted against any
Indemnitee in respect of which indemnity may be sought pursuant to the preceding
subsection, such Indemnitee shall promptly notify the Borrower. The Borrower
shall not be liable for any costs or expenses in connection with any settlement
entered into without its consent.

         SECTION 9.04. Sharing of Set-Offs. Each Bank agrees that if it shall,
by exercising any right of set-off or counterclaim or otherwise, receive payment
of a proportion of the aggregate amount of principal and interest due with
respect to any Promissory Note held by it which is greater than the proportion
received by any other Bank in respect of the aggregate amount of principal and
interest due with respect to any Promissory Note held by such other Bank, the
Bank receiving such proportionately greater payment shall purchase such
participations in the Promissory Notes held by the other Banks, and such other
adjustments shall be made, as may be required, so that all such payments of
principal and interest with respect to the Promissory Notes held by the Banks
shall be shared by the Banks pro rata; provided that nothing in this Section
shall impair the right of any Bank to exercise any right of set-off or
counterclaim it may have and to apply the amount subject to such exercise to the
payment of indebtedness of the Borrower other than its indebtedness under the
Promissory Notes.

         SECTION 9.05. Amendments and Waivers. Any provision of this Agreement
or the Promissory Notes may be amended or waived if, but only if, such amendment
or waiver is in writing and is signed by the Borrower and the Required Banks
(and, if the rights or duties of the Agent are affected thereby, by the Agent);
provided that no such amendment or waiver shall, unless signed by all the Banks,
(i) increase or decrease the Commitment of any Bank (except for a ratable
decrease in the Commitments of all Banks) or subject any Bank to any additional
obligation, (ii) reduce the principal of or rate of interest on any Loan or any
fees hereunder, (iii) postpone the date fixed for any payment of principal of or
interest on any Loan or any fees hereunder or for termination of any Commitment,
(iv) change the percentage of the 


                                       60

<PAGE>   66
Commitments or of the aggregate unpaid principal amount of the Promissory Notes,
or the number of Banks, which shall be required for the Banks or any of them to
take any action under this Section or any other provision of this Agreement or
(v) release the Parent Guarantor from its obligations under the Parent
Guarantee.

         SECTION 9.06. Successors and Assigns. (a) The provisions of this
Agreement shall be binding upon and inure to the benefit of the parties hereto
and their respective successors and assigns, except that the Borrower may not
assign or otherwise transfer any of its rights under this Agreement without the
prior written consent of all Banks.

         (b) Any Bank may at any time grant to one or more banks or other
institutions (each a "Participant") participating interests in its Commitment or
any or all of its Loans. In the event of any such grant by a Bank of a
participating interest to a Participant, whether or not upon notice to the
Borrower and the Agent, such Bank shall remain responsible for the performance
of its obligations hereunder, and the Borrower and the Agent shall continue to
deal solely and directly with such Bank in connection with such Bank's rights
and obligations under this Agreement. Any agreement pursuant to which any Bank
may grant such a participating interest shall provide that such Bank shall
retain the sole right and responsibility to enforce the obligations of the
Borrower hereunder including, without limitation, the right to approve any
amendment, modification or waiver of any provision of this Agreement; provided
that such participation agreement may provide that such Bank will not agree to
any modification, amendment or waiver of this Agreement described in clause (i),
(ii), (iii) or (iv) of Section 9.05 without the consent of the Participant. The
Borrower agrees that each Participant shall, to the extent provided in its
participation agreement and subject to subsection (e), (f) and (g) below, be
entitled to the benefits of Article 8 with respect to its participating
interest. An assignment or other transfer which is not permitted by subsection
9.06(c) or 9.06(d) below shall be given effect for purposes of this Agreement
only to the extent of a participating interest granted in accordance with this
subsection (b).

         (c) Any Bank may at any time assign to one or more banks or other
institutions (each an "Assignee") all, or a proportionate part (in an amount
equivalent to an original Commitment of not less than $10,000,000) of all, of
its rights and obligations under this Agreement and the Promissory Notes, and
such Assignee shall assume such rights and obligations, pursuant to an
Assignment and Assumption Agreement in substantially the form of Exhibit G
hereto executed by such Assignee and such transferor Bank, with (and subject to)
the subscribed consent of the Borrower and the Agent, which shall not be
unreasonably withheld; provided that if an Assignee is an affiliate of such
transferor Bank, no such consent shall be required; and provided further that
such assignment may, but need not, include rights of the transferor Bank in
respect of outstanding Money Market Loans. Upon execution and delivery of such
instrument and payment by such Assignee to such transferor Bank of an amount
equal to the purchase price agreed between such transferor Bank and such
Assignee, such Assignee shall be a Bank party to this Agreement and shall have
all the rights and obligations of a Bank with a Commitment as set forth in such
instrument of assumption, and the transferor Bank shall be released from its
obligations hereunder to a corresponding extent, and no further consent or
action by any party


                                       61

shall be required. Upon the consummation of any assignment pursuant to this
subsection (c), the transferor Bank, the Agent and the Borrower shall make
appropriate arrangements so that, if required, a new Promissory Note is issued
to the Assignee. In connection with any such assignment, the transferor Bank
shall pay to the Agent an administrative fee for processing such assignment in
the amount of $2,500. If the Assignee is not incorporated under the laws of the
United States of America or a state thereof, it shall deliver to the Borrower
and the Agent certification as to exemption from deduction or withholding of any
United States federal income taxes in accordance with Section 8.04.

         (d) Any Bank may at any time assign all or any portion of its rights
under this Agreement and its Promissory Note to a Federal Reserve Bank. No such
assignment shall release the transferor Bank from its obligations hereunder.

         (e) No Assignee, Participant or other transferee of any Bank's rights
shall be entitled to receive any greater payment under Section 8.03 or 8.04 than
such Bank would have been entitled to receive with respect to the rights
transferred, unless such transfer is made with the Borrower's prior written
consent or by reason of the provisions of Section 8.02, 8.03 or 8.04 requiring
such Bank to designate a different Applicable Lending Office under certain
circumstances or at a time when the circumstances giving rise to such greater
payment did not exist.

         (f) Notwithstanding anything to the contrary contained in this Section
9.06 but subject to the terms and conditions set forth in this subsection (f),
any Bank may from time to time, elect to designate a Conduit to provide all or
any part of Loans required to be made by such Bank to the Borrower pursuant to
this Agreement or to acquire a participation interest in any Loans extended by
such Bank hereunder (a "CONDUIT DESIGNATION"), provided the designation of a
Conduit by any Bank for purposes of this Section 9.06(f) shall be subject to the
approval of the Borrower. No additional Note shall be required with regard to a
Conduit Designation; provided, however, to the extent any Conduit shall advance
funds under a Conduit Designation, the designating Bank shall be deemed to hold
the Note in its possession as an agent for such Conduit to the extent of the
Loan funded by such Conduit. Notwithstanding any such Conduit Designation, (x)
the designating Bank shall remain solely responsible to the other parties hereto
for its obligations under this Agreement and (y) the Borrower and the Agent may
continue to deal solely and directly with the designating Bank as administrative
agent for such designating Bank's Conduit, in connection with all of such
Conduit's rights and obligations under this Agreement, unless and until the
Borrower and the Agent are notified that the designating Bank has been replaced
as administrative agent for its Conduit; any payments for the benefit of any
designating Bank and its Conduit shall be paid to such designating Bank for
itself as administrative agent for its Conduit, as applicable; provided neither
the Borrower nor the Agent shall be responsible for any designating Bank's
application of any such payments. In addition, any Conduit may (i) with notice
to, but without the prior written consent of the Borrower and the Agent, and
without paying any processing fee therefor, assign all or portions of its
interest in any Loans to the Bank that designated such Conduit or to any
financial institutions consented to by the Borrower and the Agent providing
liquidity and/or credit facilities to or for the account of such Conduit to
support the funding or maintenance of Loans and (ii) disclose on a confidential


                                       62

<PAGE>   68
basis any non-public information relating to its Loans to any rating agency,
commercial paper dealer or provider of any guarantee, surety, credit or
liquidity enhancement to such Conduit.

         (g) Each party to this Agreement hereby agrees that, at any time a
Conduit Designation is in effect, it shall not institute against, or join any
other person in instituting against, any Conduit any bankruptcy, reorganization,
arrangement, insolvency or liquidation proceeding or other proceedings under any
federal or state bankruptcy or similar law, for one year and a day after the
latest maturing commercial paper note issued by such Conduit is paid. This
Section 9.06(g) shall survive the termination of this Agreement.

         SECTION 9.07. Collateral. Each of the Banks represents to the Agent and
each of the other Banks that it in good faith is not relying upon any "margin
stock" (as defined in Regulation U) as collateral in the extension or
maintenance of the credit provided for in this Agreement.

         SECTION 9.08. Governing Law; Submission to Jurisdiction. THIS AGREEMENT
AND EACH PROMISSORY NOTE SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH
THE LAWS OF THE STATE OF NEW YORK. THE BORROWER HEREBY SUBMITS TO THE
NONEXCLUSIVE JURISDICTION OF THE UNITED STATES DISTRICT COURT FOR THE SOUTHERN
DISTRICT OF NEW YORK AND OF ANY NEW YORK STATE COURT SITTING IN NEW YORK CITY
FOR PURPOSES OF ALL LEGAL PROCEEDINGS ARISING OUT OF OR RELATING TO THIS
AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY. THE BORROWER IRREVOCABLY
WAIVES, TO THE FULLEST EXTENT PERMITTED BY LAW, ANY OBJECTION WHICH IT MAY NOW
OR HEREAFTER HAVE TO THE LAYING OF THE VENUE OF ANY SUCH PROCEEDING BROUGHT IN
SUCH A COURT AND ANY CLAIM THAT ANY SUCH PROCEEDING BROUGHT IN SUCH A COURT HAS
BEEN BROUGHT IN AN INCONVENIENT FORUM.

         SECTION 9.09. Counterparts; Integration. This Agreement may be signed
in any number of counterparts, each of which shall be an original, with the same
effect as if the signatures thereto and hereto were upon the same instrument.
This Agreement constitutes the entire agreement and understanding among the
parties hereto and supersedes any and all prior agreements and understandings,
oral or written, relating to the subject matter hereof.

         SECTION 9.10. Waiver of Jury Trial. EACH OF THE BORROWER, THE AGENT AND
THE BANKS HEREBY IRREVOCABLY WAIVES ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY
LEGAL PROCEEDING ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE
TRANSACTIONS CONTEMPLATED HEREBY.

         SECTION 9.11. Judgment Currency. If, under any applicable law and
whether pursuant to a judgment being made or registered against the Borrower or
for any other reason, any payment under or in connection with this Agreement, is
made or satisfied in a currency (the "Other Currency") other than that in which
the relevant payment is due (the "Required Currency") then, to the extent that
the payment (when converted into the Required Currency at the rate of exchange
on the date of payment or, if it is not practicable for the party entitled
thereto (the "Payee") to purchase the Required Currency with the other Currency
on the date of payment, at the rate of exchange as soon thereafter as it is
practicable for it to do so) actually received by the Payee falls short of the
amount due under the terms of this Agreement, the Borrower shall, to the extent
permitted by law, as a separate and independent obligation, indemnify and hold
harmless the Payee against the amount of such short-fall. For the purpose of
this Section, "rate of exchange" means the rate at which the Payee is able on
the relevant date to purchase the Required Currency with the Other Currency and
shall take into account any premium and other costs of exchange.

                                 of the Borrower


                                             [Effective Date]


To the Banks and the Agent
Named on the Attached Distribution List
c/o Morgan Guaranty Trust Company
of New York, As Agent
60 Wall Street
New York, New York 10260
Ladies and Gentlemen:


         I am the General Counsel of Tyco International (US) Inc., a
Massachusetts corporation (the "Borrower") and am rendering this opinion in
connection with that certain 364-Day Credit Agreement and that certain
Extendible 364-Day Credit Agreement (collectively, the "Credit Agreements"),
each dated as of February 13, 1998, among the Borrower, the banks listed on the
signature pages thereof (the "Banks") and Morgan Guaranty Trust Company of New
York, as Agent. This opinion is being delivered to you pursuant to Section
3.01(e) of each Credit Agreement. Each term defined in the Credit Agreements and
used herein, but not otherwise defined herein, has the meaning ascribed thereto
in the Credit Agreements.

         In connection with the opinion set forth herein, I have reviewed the
Credit Agreements, the Promissory Notes of the Borrower and the Parent Guarantee
and have examined originals or copies, certified or otherwise identified to my
satisfaction, of (i) the Restated Articles of Organization and By-laws of the
Borrower, each as in effect on the date hereof and (ii) such other documents,
records, certificates and instruments as I have deemed relevant and necessary as
a basis for the opinion hereinafter expressed.

         In my examination, I have assumed the genuineness of all signatures on
original documents, the authenticity of all documents submitted to me as
originals, the conformity to the originals of all copies submitted to me as
certified, conformed or photostatic copies, and the authenticity of the
originals of such copies. As to various questions of fact material to this
opinion, I have relied, without independent investigation or verification, upon
statements, representations and certificates of officers and other
representatives of the Borrower and certificates of public officials. In
addition, I have assumed that (i) the Credit Agreements have been validly
authorized, executed and delivered by all parties thereto (other than the
Borrower), (ii) each party to the Credit Agreements (other than the Borrower)
has been duly organized and is a corporation or other entity validly existing
and in good standing (to the extent applicable) under the laws of its respective
jurisdiction of organization, with the full corporate or other



<PAGE>   87
organizational power to execute and deliver the Credit Agreements and to perform
its respective obligations thereunder, (iii) the Credit Agreements constitute
the legal, valid and binding obligations of the respective parties thereto
(other than the Borrower) enforceable against such parties in accordance with
their respective terms, (iv) the execution and delivery of the Credit Agreements
by each party thereto (other than the Borrower) and the performance by such
parties of their respective obligations thereunder do not violate such parties'
respective articles or certificate of incorporation or by-laws, or other
organizational documents, and (v) the execution, delivery and performance by
each party to the Credit Agreements (other than the Borrower) and the
performance by such parties of their respective obligations thereunder do not
violate any agreement, judgment, injunction, decree, order of any governmental
authority, other instrument, law or regulation applicable to such party.

         Based upon the foregoing, and subject to the qualifications and
assumptions set forth herein, it is my opinion that:

         1. The Borrower is a corporation duly incorporated, validly existing
and in good standing under the laws of the Commonwealth of Massachusetts, and
has all corporate powers and all material governmental licenses, authorizations,
consents and approvals (collectively, the "Consents") required to carry on its
business as now conducted, other than those powers and Consents, the failure of
which to be possessed or obtained could not, based upon the facts and
circumstances in existence on the date hereof, reasonably be expected to have a
Material Adverse Effect.

         2. The execution, delivery and performance by the Borrower of the
Credit Agreements and the Promissory Notes (a) are within the Borrower's
corporate powers; (b) have been duly authorized by all necessary corporate
action on the part of the Borrower; (c) require no action by or in respect of,
or filing with, any governmental body, agency or official, in each case, on the
part of the Borrower; and (d) do not contravene, or constitute a default by the
Borrower under, any provision of (i) applicable law or regulation, (ii) the
certificate of incorporation or by-laws of the Borrower or, (iii) any agreement
or instrument evidencing or governing Debt of the Borrower, or any other
agreement, judgment, injunction, order, decree or other instrument binding upon
the Borrower.

         3. Each Credit Agreement constitutes a valid and binding agreement of
the Borrower and each Promissory Note constitutes a valid and binding obligation
of the Borrower.

         4. There is no action, suit or proceeding pending against, or, to the
best of my knowledge, threatened against or affecting, the Borrower or any of
its Subsidiaries before any court or arbitrator or any governmental body, agency
or official, in which there is a reasonable possibility of an adverse decision
which could, based upon the facts and circumstances in existence on the date
hereof, reasonably be expected to have a Material Adverse Effect or which in any
manner draws into question the validity of the Financing Documents.


                                        2

<PAGE>   88
         5. Each of the Borrower's corporate Subsidiaries is a corporation
validly existing and in good standing under the laws of its jurisdiction of
incorporation, except where the failure to be so incorporated, existing or in
good standing could not, based upon the facts and circumstances existing on the
date hereof, reasonably be expected to have a Material Adverse Effect, and has
all corporate powers and all Consents required to carry on its business as now
conducted other than those powers and Consents, the failure of which to be
possessed or obtained could not, based upon the facts and circumstances in
existence on the date hereof, reasonably be expected to have a Material Adverse
Effect.

         The opinion set forth herein is subject to the following qualifications
and limitations:

         (a) The enforceability of the Credit Agreements and the Promissory
Notes may be subject to or limited by bankruptcy, insolvency, reorganization,
arrangement, moratorium, fraudulent conveyance or transfer or other similar laws
and court decisions, now or hereafter in effect, relating to or affecting the
rights of creditors generally.

         (b) The enforceability of the Credit Agreements and the Promissory
Notes is or will be subject to the application of and may be limited by general
principles of equity including, without limitation, concepts of materiality,
reasonableness, good faith and fair dealing (regardless of whether considered in
a proceeding in equity or at law). Such principles of equity are of general
application, and in applying such principles a court, among other things, might
not allow a creditor to accelerate maturity of a debt under certain
circumstances including, without limitation, upon the occurrence of a default
deemed immaterial, or might decline to order the Borrower or any of the other
parties to the Financing Documents to perform covenants. Such principles as
applied by a court might include a requirement that a creditor act with
reasonableness and in good faith. Thus, I express no opinion as to the validity
or enforceability of (i) provisions restricting access to legal or equitable
remedies, such as the specific performance of executory covenants, (ii)
provisions that purport to establish evidentiary standards, (iii) provisions
relating to waivers, severability, set-off, or delay or omission of enforcement
of rights or remedies, and (iv) provisions purporting to convey rights to
persons other than parties to the Financing Documents.

         (c) The remedy of specific performance and injunctive and other forms
of equitable relief are subject to equitable defenses and to the discretion of
the court before which any proceeding therefor may be brought.

         (d) I have not been requested to render, and with your permission I do
not express, any opinion as to the applicability to any provision of the
Financing Documents, of Section 548 of the Federal Bankruptcy Code, Article 10
of the New York Debtor & Creditor Law, or any other fraudulent conveyance,
insolvency or transfer laws or any court decisions with respect to any of the
foregoing.

         I call your attention to the fact that I am admitted to practice law
only in the State of New York and the Commonwealth of Massachusetts, and, in
rendering the foregoing opinion, I do not express any opinion as to any laws
other than the laws of the State of New York, the Commonwealth of Massachusetts
and the Federal laws of the United States of America.

         The opinion expressed herein is based upon the laws in effect on the
date hereof, and I assume no obligation to revise or supplement this opinion
should any such law be changed by legislative action, judicial decision, or
otherwise.

         This opinion is being delivered to you solely for your benefit in

hereof may be delivered to, or used, referred to or relied upon, by any other
person or for any other purpose without my express prior written consent, except
that any person who is a permitted successor or assign of a Bank in accordance
with the provisions of the Credit Agreement may rely upon this opinion as if it
were specifically addressed and delivered to such person on the date hereof.

                                             Very truly yours,

                       Form of Opinion of General Counsel
                of the Borrower on Behalf of the Parent Guarantor


                                               [Effective Date]


To the Banks and the Agent
Named on the Attached Distribution List
c/o Morgan Guaranty Trust Company
of New York, As Agent
60 Wall Street
New York, New York 10260
Ladies and Gentlemen:


         I am the General Counsel of Tyco International (US) Inc., a
Massachusetts corporation and a wholly owned indirect subsidiary of Tyco
International Ltd., a Bermuda corporation (the "Parent Guarantor") and am
rendering this opinion in connection with that certain Parent Guarantee (the
"Parent Guarantee"), dated as of February 13, 1998, entered into by the Parent
Guarantor pursuant to that certain 364-Day Credit Agreement and that certain
Extendible 364- Day Credit Agreement (collectively, the "Credit Agreements"),
each dated as of February 13, 1998, among Tyco International (US) Inc. (the
"Borrower"), the banks listed on the signature pages thereof (the "Banks") and
Morgan Guaranty Trust Company of New York, as Agent. This opinion is being
delivered to you pursuant to Section 3.01(e) of each Credit Agreement. Each term
defined in the Credit Agreements and used herein, but not otherwise defined
herein, has the meaning ascribed thereto in the Credit Agreements.

         In connection with the opinion set forth herein, I have reviewed the
Credit Agreements, the Promissory Notes of the Borrower and the Parent Guarantee
and have examined originals or copies, certified or otherwise identified to my
satisfaction, of (i) the [Memorandum of Association and By-laws] of the Parent
Guarantor, each as in effect on the date hereof and (ii) such other documents,
records, certificates and instruments as I have deemed relevant and necessary as
a basis for the opinion hereinafter expressed.

         In my examination, I have assumed the genuineness of all signatures on
original documents, the authenticity of all documents submitted to me as
originals, the conformity to the originals of all copies submitted to me as
certified, conformed or photostatic copies, and the authenticity of the
originals of such copies. As to various questions of fact material to this
opinion, I have relied, without independent investigation or verification, upon
statements, representations and certificates of officers and other
representatives of the Parent Guarantor and certificates of public officials.



<PAGE>   91
         Based upon the foregoing, and subject to the qualifications and
assumptions set forth herein, it is my opinion that:

         1. The execution, delivery and performance by the Parent Guarantor of
the Parent Guarantee (a) require no action by or in respect of, or filing with,
any governmental body, agency or official, in each case, on the part of the
Parent Guarantor; and (b) do not contravene, or constitute a default by the
Parent Guarantor under, any provision of (i) applicable law or regulation or
(ii) any agreement or instrument evidencing or governing Debt of the Parent
Guarantor, or any other agreement, judgment, injunction, order, decree or other
instrument binding upon the Parent Guarantor.

         2. The Parent Guarantee constitutes a valid and binding obligation of
the Parent Guarantor.

         3. There is no action, suit or proceeding pending against, or, to the
best of my knowledge, threatened against or affecting, the Parent Guarantor or
any of its Subsidiaries before any court or arbitrator or any governmental body,
agency or official, in which there is a reasonable possibility of an adverse
decision which could, based upon the facts and circumstances in existence on the
date hereof, reasonably be expected to have a Material Adverse Effect or which
in any manner draws into question the validity of the Financing Documents.

         4. Each of the Parent Guarantor's corporate Subsidiaries is a
corporation validly existing and in good standing under the laws of its
jurisdiction of incorporation, except where the failure to be so incorporated,
existing or in good standing could not, based upon the facts and circumstances
existing on the date hereof, reasonably be expected to have a Material Adverse
Effect, and has all corporate powers and all Consents required to carry on its
business as now conducted other than those powers and Consents, the failure of
which to be possessed or obtained could not, based upon the facts and
circumstances in existence on the date hereof, reasonably be expected to have a
Material Adverse Effect.

         The opinion set forth herein is subject to the following qualifications
and limitations:

         (a) The enforceability of the Parent Guarantee may be subject to or
limited by bankruptcy, insolvency, reorganization, arrangement, moratorium,
fraudulent conveyance or transfer or other similar laws and court decisions, now
or hereafter in effect, relating to or affecting the rights of creditors
generally.

         (b) The enforceability of the Parent Guarantee is or will be subject to
the application of and may be limited by general principles of equity including,
without limitation, concepts of materiality, reasonableness, good faith and fair
dealing (regardless of whether considered in a proceeding in equity or at law).
Such principles of equity are of general application, and in applying such
principles a court, among other things, might not allow a creditor to accelerate
maturity of a debt under certain circumstances including, without limitation,
upon the occurrence


                                       2

<PAGE>   92
of a default deemed immaterial, or might decline to order the Parent Guarantor
or any of the other parties to the Financing Documents to perform covenants.
Such principles as applied by a court might include a requirement that a
creditor act with reasonableness and in good faith. Thus, I express no opinion
as to the validity or enforceability of (i) provisions restricting access to
legal or equitable remedies, such as the specific performance of executory
covenants, (ii) provisions that purport to establish evidentiary standards,
(iii) provisions relating to waivers, severability, set-off, or delay or
omission of enforcement of rights or remedies, and (iv) provisions purporting to
convey rights to persons other than parties to the Financing Documents.

         (c) The remedy of specific performance and injunctive and other forms
of equitable relief are subject to equitable defenses and to the discretion of
the court before which any proceeding therefor may be brought.

         (d) I have not been requested to render, and with your permission I do
not express, any opinion as to the applicability to any provision of the
Financing Documents, of Section 548 of the Federal Bankruptcy Code, Article 10
of the New York Debtor & Creditor Law, or any other fraudulent conveyance,
insolvency or transfer laws or any court decisions with respect to any of the
foregoing.

         I call your attention to the fact that I am admitted to practice law
only in the State of New York and the Commonwealth of Massachusetts, and, in
rendering the foregoing opinion, I do not express any opinion as to any laws
other than the laws of the State of New York, the Commonwealth of Massachusetts
and the Federal laws of the United States of America. Insofar as the foregoing
opinion involves matters governed by the laws of Bermuda, I have relied, without
independent investigation, upon the opinion of             , a copy of which has
been delivered to you.

         The opinion expressed herein is based upon the laws in effect on the
date hereof, and I assume no obligation to revise or supplement this opinion
should any such law be changed by legislative action, judicial decision, or
otherwise.

         This opinion is being delivered to you solely for your benefit in
connection with the Financing Documents, and neither this opinion nor any part
hereof may be delivered to, or used, referred to or relied upon, by any other
person or for any other purpose without my express prior written consent, except
that any person who is a permitted successor or assign of a Bank in accordance
with the provisions of the Credit Agreement may rely upon this opinion as if it
were specifically addressed and delivered to such person on the date hereof.

                                                     Very truly yours,

                                   OPINION OF
                     DAVIS POLK & WARDWELL, SPECIAL COUNSEL
                                  FOR THE AGENT



To the Banks and the Agent
Referred to Below
c/o Morgan Guaranty Trust Company
of New York, as Agent
60 Wall Street
New York, New York 10260

Dear Sirs:


         We have participated in the preparation of the 364-Day Credit Agreement
and the Extendible 364-Day Credit Agreement (collectively, the "Credit
Agreements"), each dated as of February 13, 1998, among Tyco International (US)
Inc., a Massachusetts corporation (the "Borrower"), the banks listed on the
signature pages thereof (the "Banks") and Morgan Guaranty Trust Company of New
York, as Agent (the "Agent"), and have acted as special counsel for the Agent
for the purpose of rendering this opinion pursuant to Section 3.01(f) of the
Credit Agreements. Terms defined in the Credit Agreements are used herein as
therein defined.

         We have examined originals or copies, certified or otherwise identified
to our satisfaction, of such documents, corporate records, certificates of
public officials and other instruments and have conducted such other
investigations of fact and law as we have deemed necessary or advisable for
purposes of this opinion.

         Upon the basis of the foregoing, we are of the opinion that each Credit
Agreement constitutes a valid and binding agreement of the Borrower, that each
Promissory Note delivered on the date hereof constitutes a valid and binding
obligation of the Borrower and that the Parent Guarantee constitutes a valid and
binding obligation of the Parent Guarantor, in each case enforceable in
accordance with its terms, except as the same may be limited by bankruptcy,
insolvency or similar laws affecting creditors' rights generally and by general
principles of equity.

         We are members of the Bar of the State of New York and the foregoing
opinion is limited to the laws of the State of New York and the federal laws of
the United States of America. In giving the foregoing opinion, (i) we express no
opinion as to the effect (if any) of any law of any jurisdiction (except the
State of New York) in which any Bank is located which limits the rate of




<PAGE>   94
interest that such Bank may charge or collect and (ii) insofar as the foregoing
opinion involves matters governed by the laws of Massachusetts or Bermuda, we
have relied, without independent investigation, upon the respective opinions of
the General Counsel of the Borrower [and the Parent Guarantor] and of Appleby,
Spurling & Kempe, special Bermuda counsel for the Parent Guarantor, copies of
which have been delivered to you.

         This opinion is rendered solely to you in connection with the above
matter. This opinion may not be relied upon by you for any other purpose or
relied upon by any other person without our prior written consent, except that
any person who is a permitted successor or assign of a Bank in accordance with
the provisions of the Credit Agreement may rely upon this opinion as if it were
specifically addressed and delivered to such person on the date hereof.

                                           Very truly yours,

                       ASSIGNMENT AND ASSUMPTION AGREEMENT



         AGREEMENT dated as of _________, ____ among [ASSIGNOR] (the
"Assignor"), [ASSIGNEE] (the "Assignee"), [NAME OF BORROWER] (the "Borrower")
and MORGAN GUARANTY TRUST COMPANY OF NEW YORK, as Agent (the "Agent").



                               W I T N E S S E T H

         WHEREAS, this Assignment and Assumption Agreement (the "Agreement")
relates to the Extendible 364-Day Credit Agreement dated as of February 13, 1998
among the Borrower, the Assignor and the other Banks party thereto, as Banks,
and the Agent (the "Credit Agreement");

         WHEREAS, as provided under the Credit Agreement, the Assignor has a
Commitment to make Loans to the Borrower in an aggregate principal amount at any
time outstanding not to exceed $__________;

         WHEREAS, Committed Loans made to the Borrower by the Assignor under the
Credit Agreement in the aggregate principal amount of $__________ are
outstanding at the date hereof; and

         WHEREAS, the Assignor proposes to assign to the Assignee all of the
rights of the Assignor under the Credit Agreement in respect of a portion of its
Commitment thereunder in an amount equal to $__________ (the "Assigned Amount"),
together with a corresponding portion of its outstanding Committed Loans, and
the Assignee proposes to accept assignment of such rights and assume the
corresponding obligations from the Assignor on such terms;

         NOW, THEREFORE, in consideration of the foregoing and the mutual
agreements contained herein, the parties hereto agree as follows:

         SECTION 1.  Definitions.  All capitalized terms not otherwise defined 
herein shall have the respective meanings set forth in the Credit Agreement.

         SECTION 2. Assignment. The Assignor hereby assigns and sells to the
Assignee all of the rights of the Assignor under the Credit Agreement to the
extent of the Assigned Amount, and the 
<PAGE>   96
Assignee hereby accepts such assignment from the Assignor and assumes all of the
obligations of the Assignor under the Credit Agreement to the extent of the
Assigned Amount, including the purchase from the Assignor of the corresponding
portion of the principal amount of the Committed Loans made by the Assignor
outstanding at the date hereof. Upon the execution and delivery hereof by the
Assignor, the Assignee, [the Borrower and the Agent] and the payment of the
amounts specified in Section 3 required to be paid on the date hereof (i) the
Assignee shall, as of the date hereof, succeed to the rights and be obligated to
perform the obligations of a Bank under the Credit Agreement with a Commitment
in an amount equal to the Assigned Amount, and (ii) the Commitment of the
Assignor shall, as of the date hereof, be reduced by a like amount and the
Assignor released from its obligations under the Credit Agreement to the extent
such obligations have been assumed by the Assignee. The assignment provided for
herein shall be without recourse to the Assignor.

         SECTION 3. Payments. As consideration for the assignment and sale
contemplated in Section 2 hereof, the Assignee shall pay to the Assignor on the
date hereof in Federal funds the amount heretofore agreed between them.* It is
understood that facility fees in respect of the Assigned Amount accrued to the
date hereof are for the account of the Assignor and such fees accruing from and
including the date hereof are for the account of the Assignee. Each of the
Assignor and the Assignee hereby agrees that if it receives any amount under the
Credit Agreement which is for the account of the other party hereto, it shall
receive the same for the account of such other party to the extent of such other
party's interest therein and shall promptly pay the same to such other party.

         [SECTION 4. Consent of the Borrower and the Agent. This Agreement is
conditioned upon the consent of the Borrower and the Agent pursuant to Section
9.06(c) of the Credit Agreement. The execution of this Agreement by the Borrower
and the Agent is evidence of this consent. Pursuant to Section 9.06(c) the
Borrower agrees to execute and deliver a Note payable to the order of the
Assignee to evidence the assignment and assumption provided for herein.]

         SECTION 5. Non-Reliance on Assignor. The Assignor makes no
representation or warranty in connection with, and shall have no responsibility
with respect to, the solvency, financial condition, or statements of the
Borrower, or the validity and enforceability of the obligations of the Borrower
in respect of the Credit Agreement or any Note. The Assignee acknowledges that
it has, independently and without reliance on the Assignor, and based on such
documents and information as it has deemed appropriate, made its own credit
analysis and decision to enter into this Agreement and will continue to be
responsible for making its own independent appraisal of the business, affairs
and financial condition of the Borrower.

- --------

              *Amount should combine principal together with accrued interest
and breakage compensation, if any, to be paid by the Assignee, net of any
portion of any upfront fee to be paid by the Assignor to the Assignee. It may be
preferable in an appropriate case to specify these amounts generically or by
formula rather than as a fixed sum.



                                       2
<PAGE>   97
         SECTION 6. Governing Law. This Agreement shall be governed by and
construed in accordance with the laws of the State of New York. 

         SECTION 7. Counterparts. This Agreement may be signed in any number of
counterparts, each of which shall be an original, with the same effect as if the
signatures thereto and hereto were upon the same instrument.

         IN WITNESS WHEREOF, the parties have caused this Agreement to be
executed and delivered by their duly authorized officers as of the date first
above written.

                              SUBSIDIARY GUARANTEE

                            Dated as of ____________


         WHEREAS, [Name of Borrower], a ___________ corporation, has entered
into a 364- Day Credit Agreement and an Extendible 364-Day Credit Agreement
(collectively, as the same may be amended from time to time, the "Credit
Agreements") each dated as of February 13, 1998 among the Borrower, the banks
listed on the signature pages thereof, and Morgan Guaranty Trust Company of New
York, as Agent, pursuant to which the Borrower is entitled, subject to certain
conditions, to borrow up to $2,250,000,000;

         WHEREAS, in conjunction with the transactions contemplated by the
Credit Agreements and in consideration of the financial and other support that
the Borrower has provided, and such financial and other support as the Borrower
may in the future provide, to the undersigned (together with its successors, the
"Guarantor") and in order to induce the Banks and the Agent to enter into the
Credit Agreements and to make Loans thereunder, the Guarantor is willing to
guarantee the obligations of the Borrower under the Credit Agreements and the
Promissory Notes issued thereunder;

         NOW, THEREFORE, in consideration of the premises and other good and
valuable consideration, the receipt and sufficiency of which are hereby
acknowledged, the Guarantor hereby agrees as follows:



                                     ARTICLE


                                   DEFINITIONS

         SECTION 1. Definitions. Terms defined in the Credit Agreements and not
otherwise defined herein are used herein as therein defined (e.g., a "Loan" is a
Loan made pursuant to either Credit Agreement and a "Promissory Note" is a
Promissory Note issued pursuant to either Credit Agreement). In addition the
following terms, as used herein, have the following meanings:

         "Guaranteed Obligations" means (i) all obligations of the Borrower in
respect of principal of and interest on the Loans and the Promissory Notes, (ii)
all other amounts payable by the Borrower under either Credit Agreement or any
Promissory Note and (iii) all renewals or extensions of the foregoing, in each
case whether now outstanding or hereafter arising. The Guaranteed Obligations
shall include, without limitation, any interest, costs, fees and expenses which
accrue on or with respect to any of the foregoing and are payable by the
Borrower pursuant to either Credit Agreement or any Promissory Note, whether
before or after the 
<PAGE>   99
commencement of any case, proceeding or other action relating to the bankruptcy,
insolvency or reorganization of any one or more than one of the Obligors, and
any such interest, costs, fees and expenses that would have accrued thereon or
with respect thereto and would have been payable by the Borrower pursuant to
such Credit Agreement or Promissory Note but for the commencement of such case,
proceeding or other action.



                                     ARTICLE


                                    GUARANTEE

         SECTION 1. The Guarantees. Subject to Section 3, the Guarantor hereby
unconditionally and irrevocably guarantees to the Banks and the Agent and to
each of them, the due and punctual payment of all Guaranteed Obligations as and
when the same shall become due and payable, whether at maturity, by declaration
or otherwise, according to the terms thereof. In case of failure by the Borrower
punctually to pay the indebtedness guaranteed hereby, the Guarantor, subject to
Section 3, hereby unconditionally agrees to cause such payment to be made
punctually as and when the same shall become due and payable, whether at
maturity or by declaration or otherwise, and as if such payment were made by the
Borrower.

         SECTION 2. Guarantee unconditional. The obligations of the Guarantor
under this Article 2 shall be unconditional and absolute and, without limiting
the generality of the foregoing, shall not be released, discharged or otherwise
affected by:

         (a) any extension, renewal, settlement, compromise, waiver or release
in respect of any obligation of any other Obligor under any Financing Document,
by operation of law or otherwise;

         (b) any modification or amendment of or supplement to any Financing
Document (other than as specified in an amendment or waiver of this Subsidiary
Guarantee effected in accordance with Section 3);

         (c) any modification, amendment, waiver, release, non-perfection or
invalidity of any direct or indirect security, or of any guaranty or other
liability of any third party, for any obligation of any other Obligor under any
Financing Document;

         (d) any change in the corporate existence, structure or ownership of
any other Obligor, or any insolvency, bankruptcy, reorganization or other
similar proceeding affecting any other Obligor or its assets or any resulting
release or discharge of any obligation of any other Obligor contained in any
Financing Document [(including, without limitation, any change in the identity
of the Borrower from Tyco US to Tyco Luxembourg as contemplated by Section 3.04
of the Credit Agreements)] [to be included in Subsidiary Guarantees issued while
Tyco US is the Borrower];



                                       2
<PAGE>   100
         (e) the existence of any claim, set-off or other rights which the
Guarantor may have at any time against any other Obligor, the Agent, any Bank or
any other Person, whether or not arising in connection with the Financing
Documents; provided that nothing herein shall prevent the assertion of any such
claim by separate suit or compulsory counterclaim;

         (f) any invalidity or unenforceability relating to or against any other
Obligor for any reason of any Financing Document, or any provision of applicable
law or regulation purporting to prohibit the payment by any other Obligor of the
principal of or interest on any Promissory Note or any other amount payable by
any other Obligor under any Financing Document; or

         (g) any other act or omission to act or delay of any kind by any other
Obligor, the Agent, any Bank or any other Person or any other circumstance
whatsoever that might, but for the provisions of this paragraph, constitute a
legal or equitable discharge of the obligations of the Guarantor under this
Article 2.

         SECTION 3. Limit of Liability. The Guarantor shall be liable under this
Subsidiary Guarantee only for amounts aggregating up to the largest amount that
would not render its obligations hereunder subject to avoidance under Section
548 of the United States Bankruptcy Code or any comparable provisions of any
other applicable law.

         SECTION 4. Discharge; Reinstatement in Certain Circumstances. Subject
to Section 6, the Guarantor's obligations under this Article 2 shall remain in
full force and effect until the Commitments are terminated and the principal of
and interest on the Promissory Notes and all other amounts payable by the
Borrower under the Financing Documents shall have been paid in full. If at any
time any payment of the principal of or interest on any Promissory Note or any
other amount payable by the Borrower under any Financing Document is rescinded
or must be otherwise restored or returned upon the insolvency, bankruptcy or
reorganization of any other Obligor or otherwise, the Guarantor's obligations
under this Article 2 with respect to such payment shall be reinstated at such
time as though such payment had become due but had not been made at such time.

         SECTION 5. Waiver. The Guarantor irrevocably waives acceptance hereof,
presentment, demand, protest and any notice not provided for herein, as well as
any requirement that at any time any action be taken by any Person against any
other Obligor or any other Person.

         SECTION 6. Subrogation and Contribution. (a) The Guarantor irrevocably
waives any and all rights to which it may be entitled, by operation of law or
otherwise, upon making any payment hereunder (i) to be subrogated to the rights
of the payee against the Borrower with respect to such payment or otherwise to
be reimbursed, indemnified or exonerated by any other Obligor in respect thereof
or (ii) to receive any payment, in the nature of contribution or for any other
reason, from any other Obligor with respect to such payment


                                       3
<PAGE>   101
         (b) Notwithstanding the provision of subsection (a) of this Section 6,
the Guarantor shall have and be entitled to (i) all rights of subrogation or
contribution otherwise provided by law in respect of any payment it may make or
be obligated to make under this Subsidiary Guarantee and (ii) all claims (as
defined under Chapter 11 of Title 11 of the United States Code, as amended, or
any successor statute (the "Bankruptcy Code")) it would have against the
Borrower or any other Guarantor (each an "Other Party") in the absence of
subsection (a) of this Section 6 and to assert and enforce the same, in each
case on and after, but at no time prior to, the date (the "Subrogation Trigger
Date") which is one year and five days after the Termination Date if, but only
if, (x) no Default or Event of Default of the type described in Section 6.01(i)
or 6.01(j) of the Credit Agreements with respect to the relevant Other Party has
existed at any time on and after the date of this Subsidiary Guarantee to and
including the Subrogation Trigger Date and (y) the existence of such Guarantor's
rights under this clause (b) would not make such Guarantor a creditor (as
defined in the Bankruptcy Code) of such Other Party in any insolvency,
bankruptcy, reorganization or similar proceeding commenced on or prior to the
Subrogation Trigger Date.

         SECTION 7. Stay of Acceleration. If acceleration of the time for
payment of any amount payable by the Borrower under the Financing Documents is
stayed upon the insolvency, bankruptcy or reorganization of the Borrower, all
such amounts otherwise subject to acceleration under the terms of the Financing
Documents shall nonetheless be payable by the Guarantor hereunder forthwith on
demand by the Agent made at the request of the Required Banks.

            [Form of Opinion of Counsel for the Subsidiary Guarantor]






To the Banks and the Agent
Named on the Attached Distribution List
c/o Morgan Guaranty Trust Company
of New York, as Agent
60 Wall Street
New York, New York 10260

Ladies and Gentlemen:

         I am the [Associate] General Counsel of [Name of Borrower], a
__________ corporation (the "Borrower"), and have acted as counsel for [name of
Subsidiary Guarantor] (the "Guarantor"), and am rendering this opinion in
connection with that certain Subsidiary Guarantee (the "Subsidiary Guarantee"),
dated as of __________, entered into by the Guarantor, pursuant to that certain
364-Day Credit Agreement and that certain Extendible 364-Day Credit Agreement
(collectively, the "Credit Agreements"), each dated as of February 13, 1998,
among the Borrower, the banks listed on the signature pages thereof (the
"Banks") and Morgan Guaranty Trust Company of New York, as Agent. Each term
defined in the Subsidiary Guarantee and used herein, but not otherwise defined
herein, has the meaning ascribed thereto in the Subsidiary Guarantee. This
opinion is being delivered to you pursuant to the Credit Agreements.

         In connection with the opinion set forth herein, I have reviewed the
Credit Agreements, the Promissory Notes and the Subsidiary Guarantee and have
examined originals or copies, certified or otherwise identified to my
satisfaction, of (i) the [Certificate of Incorporation] and By-laws of the
Guarantor, each as in effect on the date hereof and (ii) such other documents,
records, certificates and instruments as I have deemed relevant and necessary as
a basis for the opinion hereinafter expressed.

         In my examination, I have assumed the genuineness of all signatures on
original documents, the authenticity of all documents submitted to me as
originals, the conformity to the originals of all copies submitted to be as
certified, conformed or photostatic copies, and the authenticity of the
originals of such copies. As to various questions of fact material to this
opinion, I have relied, without independent investigation or verification, upon
statements, representations and certificates of officers and other
representatives of the Guarantor and certificates of public officials.
<PAGE>   107
         Based upon the foregoing, and subject to the qualifications and
assumptions set forth herein, it is my opinion that:

         (1) The Guarantor is a corporation duly incorporated, validly existing
and in good standing under the laws of _________________.

         (2) The execution, delivery and performance by the Guarantor of the
Subsidiary Guarantee (a) are within the Guarantor's corporate powers; (b) have
been duly authorized by all necessary corporate action on the part of the
Guarantor; (c) require no action by or in respect of, or filing on the part of
the Guarantor with, any governmental body, agency or official, in each case, on
the part of the Guarantor; and (d) do not contravene, or constitute a default by
the Guarantor under, any provision of (i) applicable law or regulation, (ii) the
certificate of incorporation or by-laws of the Guarantor or, (iii) any agreement
or instrument evidencing or governing Debt of the Guarantor, or any other
material agreement, judgment, injunction, order, decree or other instrument
binding upon the Guarantor.

         (3) The Subsidiary Guarantee constitutes a valid and binding
obligation of the Guarantor.

         (4) The Guarantor is not an "investment company" within the meaning of
the Investment Company Act of 1940, as amended.

         The opinion set forth herein is subject to the following qualifications
and limitations:

          (a) The enforceability of the Subsidiary Guarantee may be subject to
or limited by bankruptcy, insolvency, reorganization, arrangement, moratorium,
fraudulent conveyance or transfer or other similar laws and court decisions, now
or hereafter in effect, relating to or affecting the rights of creditors
generally.

          (b) The enforceability of the Subsidiary Guarantee is or will be
subject to the application of and may be limited by general principles of equity
including, without limitation, concepts of materiality, reasonableness, good
faith and fair dealing (regardless of whether considered in a proceeding in
equity or at law). Such principles of equity are of general application, and in
applying such principles a court, among other things, might not allow a creditor
to accelerate maturity of a debt under certain circumstances including, without
limitation, upon the occurrence of a default deemed immaterial, or might decline
to order the Guarantor to perform covenants. Such principles as applied by a
court might include a requirement that a creditor act with reasonableness and in
good faith. Thus, I express no opinion as to the validity or enforceability of
(i) provisions restricting access to legal or equitable remedies, such as the
specific performance of executory covenants, (ii) provisions that purport to
establish evidentiary standards, (iii) provisions relating to waivers,
severability, set-off, or delay or omission of enforcement of rights or
remedies, and (iv) provisions purporting to convey rights to persons other than
parties to the Subsidiary Guarantee.




                                       2
<PAGE>   108
         (c) The remedy of specific performance and injunctive and other forms
of equitable relief are subject to equitable defenses and to the discretion of
the court before which any proceeding therefor may be brought.

         (d) I have not been requested to render, and with your permission I
do not express, any opinion as to the applicability to any provisions of the
Subsidiary Guarantee, of Section 548 of the Federal Bankruptcy Code, Article 10
of the New York Debtor & Creditor Law, or any other fraudulent conveyance,
insolvency or transfer laws or any court decisions with respect to any of the
foregoing.

         I call your attention to the fact that I am admitted to practice law
only in the State of New York and the Commonwealth of Massachusetts, and, in
rendering the foregoing opinion, I do not express any opinion as to any laws
other than the laws of [the jurisdiction of incorporation of the Guarantor], the
State of New York, the Commonwealth of Massachusetts and the Federal laws of the
United States of America.

         The opinion expressed herein is based upon the laws in effect on the
date hereof, and I assume no obligation to revise or supplement this opinion
should any such law be changed by legislative action, judicial decision, or
otherwise.

         This opinion is being delivered to you solely for your benefit in
connection with the Subsidiary Guarantee, and neither this opinion nor any part
hereof may be delivered to, or used, referred to or relied upon, by any other
person or for any other purpose without my express prior written consent, except
that any person who is a permitted successor or assign of a Bank in accordance
with the provisions of the Credit Agreement may rely upon this opinion as if it
were specifically addressed and delivered to such person on the date hereof.

                                        Very truly yours,

                           Form of Opinion of Counsel
                            for the Parent Guarantor




To the Banks and the Agent
   named on Schedule 1 to this Opinion
c/o Morgan Guaranty Trust Company of New York (as Agent)
60 Wall Street
New York, NY 10260

Dear Sirs,

         Re: TYCO INTERNATIONAL LTD. (THE "COMPANY")

         We have been instructed by the Company to address this opinion to you
in connection with the Parent Guarantee, dated as of February 13, 1998 (the
"Guarantee"), entered into by the Company in connection with all principal of
and interest on amounts loaned to the Borrower under the Financing Documents.

         Unless otherwise defined therein, terms defined in the Guarantee have
the same meanings when used in this opinion.

         For the purpose of this opinion, we have been supplied with and have
reviewed, and relied upon the following documents:

          (A) a copy of the executed US $500,000,000 Extendible 364-Day Credit
         Agreement dated as of February 13, 1998 among the Borrower, the Banks
         listed on the signature pages thereof and the Agent;

          (B) a copy of the executed US $1,750,000,000 364-Day Credit Agreement
         dated as of February 13, 1998 among the Borrower, the Banks listed on
         the signature pages thereof and the Agent;

          (C)    a copy of the executed Subsidiary Guarantees;

          (D)   a copy of the executed Promissory Notes;

The Documents referred to in (a), (b) and (d) inclusive are together referred to
as the "Financing Documents".
<PAGE>   110
          (E)   a copy of the executed Guarantee;

          (F) certified copies of the Certificate of Incorporation, the
Certificate evidencing the change of name of the Company from ADT Limited to
TYCO International Ltd. and the Memorandum of Association and the Bye-laws of
the Company;

          (G)   a certified copy of the minutes of a meeting of the Board of
Directors of the Company held on [ ], 199_ (the "Resolutions"); and

          (H) a certified copy of the Share Certificate evidencing ownership by
the Company of [the Borrower].

         We also examined and relied upon:

          (A)   A Certificate of Compliance issued by the Registrar of
Companies on Bermuda in respect of the Company on [ ] February, 1998; and

          (B) Our searches of the documents of public record in relation
to the Company maintained by the Registrar of Companies in Bermuda made on [ ]
February, 1998 and of the Causes Book maintained by the Registrar of the Supreme
Court of Bermuda made on the same date (the "Searches").

         In giving this opinion, we have assumed:

                       (1) the capacity, power and authority of each of the
                  parties other than the company to execute, deliver and perform
                  its obligations under and the due execution and delivery by
                  all parties other than the Company of the Financing Documents
                  and the Guarantee;

                       (2) that each party, other than the Company, has duly
                  authorised, executed, delivered and taken such other action as
                  may be required by such party to enter into and perform the
                  Financing Documents and the Guarantee in the form of the
                  execution copies we have reviewed for the purpose of this
                  opinion without alteration which is material to this opinion
                  and that all such actions were duly authorised when taken;

                       (3) that no authorisation or approval by, or filing with,
                  any governmental or regulatory authority, other than such
                  authorisations, approvals and filings as each party other than
                  the Company has obtained or made, is necessary for such party
                  to duly execute and deliver, or to duly perform all of its
                  obligations under the Financing Documents and the Guarantee,
                  or for the validity and enforceability of the Financing
                  Documents and the Guarantee;


                                       2
<PAGE>   111
                       (4) that each of the Financing Documents and the
                  Guarantee constitutes the legal, valid and binding obligation
                  of each party to it, other than the Company, and is
                  enforceable against each such party in accordance with its
                  terms;

                       (5) that the Financing Documents are legal, valid and
                  binding under the laws by which they are expressed to be
                  governed and that the Guarantee is legal, valid and binding
                  under the laws of the State of New York by which it is
                  expressed to be governed;

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

                       (7) that there is no provision of the law of any
                  jurisdiction, other than Bermuda, which would have any
                  implication in relation to the opinions herein expressed;

                       (8) the genuineness of all signatures on the documents
                  which we have examined;

                       (9) the conformity to original documents of all
                  documents produced to us as copies and the authenticity of all
                  original documents which, or copies of which, have been
                  submitted to us;

                      (10) the accuracy and completeness of all factual
                  representations made in the Financing Documents, the
                  Guarantee, the Resolutions and any certificates or other
                  documents which we have examined and upon which we have
                  relied;

                      (11) that the Resolutions are in full force and effect
                  and have not been rescinded or altered in any way material to
                  this opinion; and

                      (12) that the Company is entering into its obligations
                  under the Guarantee in good faith and for the purpose of
                  carrying on its commercial business in the ordinary course
                  thereof and that there are reasonable grounds for believing
                  that the transactions contemplated by the Financing Documents
                  will benefit the Company.

         Based upon and subject to the foregoing, and subject to the
reservations set out below, to matters not disclosed to us and matters of fact
which would affect the conclusion set out below and having regard to such legal
considerations as we deem relevant, we are of the opinion that:



                                       3
<PAGE>   112
         (i). The Company is a company duly incorporated, duly organised and
validly existing under the laws of Bermuda. The Memorandum of Association of the
Company has been duly filed in the office of the Registrar of Companies of
Bermuda and no other filing, recording, publishing or other act is necessary or
appropriate in Bermuda in connection with the transaction as described in the
Guarantee except those which have been duly made or performed.

        (ii). The Company has the corporate power and authority to enter into
and perform the Guarantee and has taken all corporate action required on its
part to authorise the execution, delivery and performance of the guarantee.

       (iii). The execution, delivery and performance of the Guarantee by the
Company (i) does not and will not violate the Certificate of Incorporation,
Memorandum of Association or Bye-laws of the Company; (ii) conflict with the
Companies Act 1981 or any other law or governmental rule or regulation published
by the Bermuda Government which is applicable to the Company; and (iii) as far
as can be ascertained from the Searches (which are not conclusive) does not and
will not violate or conflict with any judgment, order, decree, injunction or
award of any authority, agency or court in Bermuda to which the Company is
subject.

        (iv). The obligations of the Company as set out in the Guarantee
constitute, legal, valid and binding obligations of the Company.

         (v). The Company having been designated as non-resident for the
purposes of the Exchange Control Act 1972, it is not necessary for the consent
of any authority or agency in Bermuda to be obtained to enable the Company to
enter into and perform its obligations set out in the Guarantee.

        (vi). The obligations of the Company under the Guarantee will rank at
least pari passu in priority of payment with all other unsecured unsubordinated
indebtedness of the Company other than indebtedness which is preferred by virtue
of any provision of Bermuda law of general application.

       (vii). As far as can be ascertained from the Searches (which are not
conclusive), no litigation, arbitration or administrative proceedings of or
before any court, arbitrator or governmental instrumentality of or in Bermuda
is, to the best of our knowledge, pending with respect to the Company in
connection with the Guarantee or the transactions contemplated thereby.

      (viii). The Company will be permitted to make all payments under the
Guarantee free of any deduction or withholding therefrom in Bermuda and such
payments will not be subject to any tax imposed by the Government of Bermuda or
any taxing authority thereof or therein.



                                       4
<PAGE>   113
         (ix). The entry into, performance and enforcement of the Guarantee will
not give rise to any registration fee or to any stamp, excise or other similar
tax imposed by the Government of Bermuda or any taxing authority thereof or
therein.

         (x). Subject to paragraph (12) and reservation (f) below, it is not
necessary or advisable under the laws of Bermuda in order to ensure the
validity, effectiveness or enforceability or admissibility in evidence of the
Guarantee that the Guarantee be filed, registered or recorded with any Court,
public office or other Bermuda regulatory authority.

        (xi). The choice of the laws of the State of New York to govern the
Guarantee is a proper, valid and binding choice of law and will be recognised
and applied by the courts of Bermuda provided that the point is specifically
pleaded and that such choice of law is a valid and binding choice of law under
the laws of the State of New York.

       (xii). A final and conclusive judgement obtained in the Courts of the
State of New York or Federal Courts of the United States of America against the
Company based upon the Guarantee under which a sum of money is payable (other
than a sum of money payable in respect of taxes or other charges of a like
nature or in respect of a fine or other penalty or in respect of Multiple
Damages as defined in the Protection of Trading Interest Act, 1981) may be the
subject of enforcement proceedings in the Supreme Court of Bermuda, without
re-examination of the merits, under the Common Law Doctrine of Obligation. A
final opinion as to the availability of this remedy should be sought when the
facts surrounding the foreign judgment are known but, on general principles, we
would expect such an application to be successful provided that:

          (A) the Court which gave the judgment was competent to hear the action
         in accordance with private international law principles as applied in
         Bermuda;

          (B) the judgment has not been obtained by fraud;

          (C) the judgment is not and its enforcement would not be contrary
         to public policy of Bermuda;

          (D) the judgment has not been obtained in proceedings contrary
         to natural justice; and

          (E) the correct procedures under the laws of Bermuda are duly complied
         with.

         Neither the Company nor any of its property or assets (or any portion
thereof) enjoys, under the laws of Bermuda, immunity from suit, execution,
attachment or other legal process in any proceedings in Bermuda in connection
with the Guarantee.

         Our reservations are as follows:



                                       5
<PAGE>   114
         (a) We are admitted to practise law in the Islands of Bermuda and we
express no opinion as to any law other than Bermuda law and none of the opinions
expressed herein relates to compliance with or matters governed by the laws of
any jurisdiction except Bermuda.

         (b) Where an obligation is to be performed in a jurisdiction other than
Bermuda, the Courts of Bermuda may refuse to enforce it to the extent that such
performance would be illegal or contrary to public policy under the laws of such
other jurisdiction.

         (c) We express no opinion as to the availability of equitable remedies,
such as specific performance or injunctive relief, or as to matters which are
within the discretion of the Courts of Bermuda such as the award of costs or
questions relating to forum non-conveniens. Further, we express no opinion as to
the validity or binding effect of any waiver of or obligation to waive any
provision of law (whether substantive or procedural) or any right or remedy
arising through circumstances not known at the time of entering into the
Financing Documents and the Guarantee.

          (d) We express no opinion as to the validity or the binding effect of
any obligations of the Borrower in the Financing Documents which provide for the
payment by the Borrower of a higher rate of interest on overdue amounts than on
amounts which are current. A Bermuda Court, even if it were applying the laws of
the State of New York might not give effect to such provision as being contrary
to public policy if it could be established that the amount expressed as being
payable was such that the provision was in the nature of a penalty; that is to
say a requirement for a stipulated sum to be paid irrespective of, or
necessarily greater than, the loss likely to be sustained. The Court will
determine and award what it considers to be reasonable damages. Section 9 of The
Interest and Credit Charges (Regulations) Act 1975 provides that the Bermuda
Courts have discretion as to the amount of interest if any payable on the amount
of a judgment after the date of judgment. If the Court does not exercise that
discretion, then interest will accrue at the statutory rate which is currently
7% per annum.

          (e) The obligations of the Company under the Guarantee will be subject
to any laws from time to time in effect relating to bankruptcy, insolvency or
liquidation or any other laws or other legal procedures affecting generally the
enforcement of creditors' rights and may also be the subject of the statutory
limitation of the time within which such proceedings may be brought.

          (f) To the extent that the Financing Documents, the Guarantee or the
transactions contemplated thereunder, create or give rise to the creation of any
charge over any assets of the Company, such charge will be registerable under
Part V of The Companies Act 1981 of Bermuda. The fee payable for registration of
a charge is $425.00. Registration is not compulsory and there is no time limit
within which it must be effected. Under Section 55 of the Companies Act, any
charge registered will have priority based on the date that it is registered and
not on the date of its creation and will have such priority over any
unregistered charge. Accordingly, it is advisable to register any such charge.



                                       6
<PAGE>   115
          (g) Any provision in the Financing Documents or the Guarantee that
certain calculations and/or certificates will be conclusive and binding will not
be effective if such calculations are fraudulent or erroneous on their face and
will not necessarily prevent enquiry into the merits of any claim by an
aggrieved party.

         (h) Where a party is vested with a discretion or may determine a matter
in its opinion, such discretion may have to be exercised reasonably or such an
opinion may have to be based on reasonable grounds.

         (i) Searches in the register of companies at the office of the
Registrar of Companies and in the Supreme Court Causes Book at the Registry of
the Supreme Court are not conclusive and it should be noted that the register of
companies and the Supreme Court Causes Book do not reveal:

               (i) whether an application to the Supreme Court for the
         appointment of a receiver or manager has been presented;

              (ii) details of matters which have been lodged for registration
         but have not actually been registered or to the extent they have been
         registered have not been disclosed or appear in the public records at
         the date the search is concluded;

             (iii) details of matters which should have been lodged for
         registration but have not been lodged for registration at the date the
         search is concluded; or

              (iv) whether a receiver or manager has been appointed privately
         out of the Supreme Court pursuant to the provisions of a debenture or
         other security, unless notice of the fact has been entered in the
         register of charges in accordance with the provisions of the Act.

          (j) A Bermuda Court may refuse to give effect to any provisions of the
Financing Documents or Guarantee in respect of costs of unsuccessful litigation
brought before the Court or where that Court has itself made an order for costs.



         This opinion is issued on the basis that it will be governed by and
construed in accordance with the provisions of Bermuda law and it is limited to
and is given on the basis of the current law and practice in Bermuda and will
not give rise to action in any other jurisdiction. It is issued solely for your
benefit for the purpose of the transactions described in the Guarantee and it is
not to be relied upon by any other person (other than permitted assigns and
transferees under the Financing Documents), or for any other purpose, without
our prior written consent.

                           Yours faithfully,



                                       7

                             NEW BORROWER AGREEMENT



         AGREEMENT dated as of ___________ among TYCO INTERNATIONAL (US) INC., a
Massachusetts corporation ("Tyco US"), TYCO GROUP S.a.r.l., a Luxembourg company
("Tyco Luxembourg"), and MORGAN GUARANTY TRUST COMPANY OF NEW YORK, as Agent
(the "Agent").

                                R E C I T A L S:

         WHEREAS, Tyco US is a party to an Extendible 364-Day Credit Agreement
dated as of February 13, 1998 (as the same has been or may hereafter be amended
from time to time, the "Credit Agreement") with the Banks listed therein and the
Agent; and

         WHEREAS, any Loans made to Tyco US by the Banks under the Credit
Agreement will be prepaid in full not later than the date of effectiveness
hereof; and

         WHEREAS, Tyco US and Tyco Luxembourg have elected that Tyco Luxembourg
shall become the Borrower under the Credit Agreement and that Tyco US shall
cease to be the Borrower thereunder;

         NOW, THEREFORE, in consideration of the foregoing and the mutual
agreements contained herein, the parties hereto agree as follows:

         SECTION 1.  Definitions. All capitalized terms not otherwise defined
herein shall have the meanings set forth in the Credit Agreement.

          SECTION 2. New Borrower. Upon the satisfaction of the conditions
referred to in Section 3.04 of the Credit Agreement, (i) each of the Banks shall
make a Loan to Tyco Luxembourg on the terms and conditions set forth in the
Credit Agreement, (ii) the proceeds of such Loans shall fund to the extent
necessary an inter-company loan by Tyco Luxembourg to Tyco US, which
inter-company loan shall fund in whole or in part the repayment of all loans to
Tyco US under the Credit Agreement and the Existing Agreements, (iii) Tyco US
shall execute a promissory note in favor of Tyco Luxembourg, in form reasonably
satisfactory to Tyco Luxembourg, to evidence such inter-company loans, (iv) Tyco

released from all
<PAGE>   117
liabilities and obligations under the Credit Agreement and the Notes to the
extent such liabilities and obligations arise from and after the effectiveness
of this Agreement and shall cease to be a party to the Credit Agreement. Nothing
in this Section shall affect the obligations of Tyco US as a Subsidiary
Guarantor.

         SECTION 3. Judicial Proceedings. (a) Consent to Jurisdiction. Tyco
Luxembourg irrevocably submits to the non-exclusive jurisdiction of any federal
or New York State court sitting in New York City over any suit, action or
proceeding arising out of or relating to the Financing Documents. Tyco
Luxembourg irrevocably waives, to the fullest extent permitted by law, any
objection which it may now or hereafter have to the laying of the venue of any
such suit, action or proceeding brought in such court and any claim that any
suit, action or proceeding brought in such court has been brought in an
inconvenient forum. Tyco Luxembourg agrees that a final judgment in any such
suit, action or proceeding brought in such a court shall be conclusive and
binding upon it and will be given effect in Luxembourg to the fullest extent
permitted by applicable law and may be enforced in any federal or New York State
court sitting in New York City (or any other courts to the jurisdiction of which
Tyco Luxembourg is or may be subject) by a suit upon such judgment, provided
that service of process is effected upon it in one of the manners specified
herein or as otherwise permitted by law.

         (b) Appointment of Agent for Service of Process. Tyco Luxembourg hereby
irrevocably designates and appoints CT Corporation System having an office on
the date hereof at 1633 Broadway, New York, New York 10019 as its authorized
agent, to accept and acknowledge on its behalf, service or any and all process
which may be served in any suit, action or proceeding of the nature referred to
in subsection (a) above in any federal or New York State court sitting in New
York City. Tyco Luxembourg represents and warrants that such agent has agreed in
writing to accept such appointment and that a true copy of such designation and
acceptance has been delivered to the Agent. Such designation and appointment
shall be irrevocable until all principal and interest and all other amounts
payable under the Financing Documents shall have been paid in full in accordance
with the provisions hereof. If such agent shall cease so to act, Tyco Luxembourg
covenants and agrees to designate irrevocably and appoint without delay another
such agent satisfactory to the Agent and to deliver promptly to the Agent
evidence in writing of such other agent's acceptance of such appointment.

         (c) Service of Process. Tyco Luxembourg hereby consents to process
being served in any suit, action, or proceeding of the nature referred to in
subsection (a) above in any federal or New York State court sitting in New York
City by service of process upon the agent of Tyco Luxembourg, as the case may
be, for service of process in such jurisdiction appointed as provided in
subsection (b) above; provided that, to the extent lawful and possible, written
notice of said service upon such agent shall be mailed by registered airmail,
postage prepaid, return receipt requested, to Tyco Luxembourg at its address
specified on the signature pages hereof or to any other address of which Tyco
Luxembourg shall have given written notice to the Agent. Tyco Luxembourg
irrevocably waives, to the fullest extent permitted by law, all claim of error
by reason of any such service and agrees that such service shall be deemed in
every respect effective


                                       2
<PAGE>   118
service of process upon Tyco Luxembourg in any such suit, action or proceeding
and shall, to the fullest extent permitted by law, be taken and held to be valid
and personal service upon and personal delivery to Tyco Luxembourg.

         (d) No Limitation on Service or Suit. Nothing in this Section shall
affect the right of the Agent or any Bank to serve process in any other manner
permitted by law or limit the right of the Agent or any Bank to bring
proceedings against Tyco Luxembourg in the courts of any jurisdiction or
jurisdictions.

         SECTION 4. Governing Law. This Agreement shall be governed by and
construed in accordance with the laws of the State of New York.

         SECTION 5. Counterparts; This Agreement may be signed in any number of
counterparts, each of which shall be an original, with the same effect as if the
signatures thereto and hereto were upon the same instrument.

         IN WITNESS WHEREOF, the parties have caused this Agreement to be
executed and delivered by their duly authorized officers as of the date first
above written.

determined as aforesaid shall be adjusted to include the additional Debt,
determined on a consolidated basis as of such date, which would have been
outstanding at such date had such Permitted Receivables Transaction been
accounted for as a borrowing at such date and (ii) Consolidated Debt shall in
any event include all Debt of any Person other than the Guarantor or a
Consolidated Subsidiary which is Guaranteed by the Guarantor or a Consolidated
Subsidiary, except that Consolidated Debt shall not include Debt of a joint
venture, partnership or similar entity which is Guaranteed by the Guarantor or a

arrangement with respect to such entity or by operation of applicable law (and

excluded Debt at any date does not exceed $50,000,000.

         the Borrower for any reason of any Financing Document, or any provision
         of applicable law or regulation purporting to prohibit the payment by
         the Borrower of any amount payable by it under any Financing Document;
         or

                (vii) any other act or omission to act or delay of any kind by
         the Borrower, the Agent, any Bank or any other Person or any other
         circumstance whatsoever which might, but for the provisions of this
         paragraph, constitute a legal or equitable discharge of or defense to
         the Guarantor's obligations hereunder.

         SECTION 2.03. Discharge Only upon Payment in Full; Reinstatement in
Certain Circumstances. This Agreement shall remain in full force and effect
until the commitments of the Banks under the Credit Agreements shall have
terminated and the principal of and interest on the Promissory Notes (as defined
in either Credit Agreement) and all other amounts payable by the Borrower under
the Financing Documents shall have been paid in full. If at any time any payment
of principal of or interest on any Promissory Note (as defined in either Credit
Agreement) or any other amount payable by the Borrower under the Financing
Documents is rescinded or must be otherwise restored or returned upon the
insolvency, bankruptcy or reorganization of the Borrower or otherwise, the
Guarantor's obligations hereunder with respect


                                       8

due but not made at such time.

         SECTION 2.04. Waiver by the Guarantor. The Guarantor irrevocably waives
acceptance hereof, presentment, demand, protest and any notice not provided for
herein, as well as any requirement that at any time any action be taken by any

         SECTION 2.05. Subrogation. Upon making any payment hereunder with
respect to the Borrower, the Guarantor shall be subrogated to the rights of the
payee against the Borrower with respect to such payment; provided that the

of principal of and interest on the Promissory Notes (as defined in either
Credit Agreement) and all other amounts payable by the Borrower under the
Financing Documents have been paid in full.

         SECTION 2.06. Stay of Acceleration. In the event that acceleration of
the time for payment of any amount payable by the Borrower under any Financing
Document is stayed upon insolvency, bankruptcy or reorganization of the
Borrower, all such amounts otherwise subject to acceleration under the terms of
this Agreement shall nonetheless be payable by the Guarantor hereunder forthwith
on demand by the Agent.

                 REPRESENTATIONS AND WARRANTIES OF THE GUARANTOR

            The Guarantor represents and warrants to the Agent that:

         SECTION 3.01. Corporate Existence and Power. The Guarantor is a company
limited by shares duly incorporated and validly existing under the laws of
Bermuda. The Guarantor has all corporate powers and all governmental licenses,
authorizations, consents and approvals (collectively, the "Consents") required
in order to carry on its business as now conducted, other than those powers and
Consents, the failure of which to be possessed or obtained could not, based upon
the facts and circumstances in existence at the time this representation and
warranty is made or deemed made, reasonably be expected to have a Material
Adverse Effect.

         SECTION 3.02. Corporate and Governmental Authorization; No
Contravention. The execution, delivery and performance by the Guarantor of this
Agreement: (a) are within the Guarantor's corporate powers; (b) have been duly
authorized by all necessary corporate action on the part of the Guarantor; (c)
require no action by or in respect of, or filing with, any governmental body,
agency or official, in each case, on the part of the Guarantor; and (d) do not
contravene, or constitute a default by the Guarantor under, any provision of (i)
applicable law or regulation, (ii) the Memorandum of Association or Bye-Laws of
the Guarantor, or (iii) any agreement or instrument evidencing or governing Debt
of the Guarantor or any other material agreement, judgment, injunction, order,
decree or other instrument binding upon the Guarantor.


                                       9
<PAGE>   13
         SECTION 3.03. Binding Effect. This Agreement constitutes a valid and
binding agreement of the Guarantor.

         SECTION 3.04. Financial Information.

         (a) The consolidated balance sheet of the Guarantor and its
Consolidated Subsidiaries as of September 30, 1997 and the related consolidated
statements of income, of shareholders' equity and of cash flows for the
nine-month period then ended, reported on by Coopers & Lybrand and set forth in
the Guarantor's 1997 Form 10-K, a copy of which has been delivered to each of
the Banks, fairly present, in conformity with generally accepted accounting
principles, the consolidated financial position of the Guarantor and its
Consolidated Subsidiaries as of such date and their consolidated results of
operations and cash flows for such period.

         (b) Since September 30, 1997 there has been no material adverse change
in the business, financial position, results of operations or Prospects of the
Guarantor and its Consolidated Subsidiaries, considered as a whole.

         SECTION 3.05. Litigation. There is no action, suit or proceeding
pending against, or to the knowledge of the Guarantor threatened against or
affecting, the Guarantor or any of its Subsidiaries before any court or
arbitrator or any governmental body, agency or official in which there is a
reasonable possibility of an adverse decision which could, based upon the facts
and circumstances in existence at the time this representation and warranty is
made or deemed made, reasonably be expected to have a Material Adverse Effect or
which in any manner draws into question the validity of the Financing Documents.

         SECTION 3.06. Environmental Matters. In the ordinary course of its
business, the Guarantor conducts an ongoing review of the effect of
Environmental Laws on the business, operations and properties of the Guarantor
and its Subsidiaries, in the course of which it identifies and evaluates
associated liabilities and costs (including, without limitation, any capital or
operating expenditures required for clean-up or closure of properties presently
or previously owned, any capital or operating expenditures required to achieve
or maintain compliance with environmental protection standards imposed by law or
as a condition of any license, permit or contract, any related constraints on
operating activities, including any periodic or permanent shutdown of any
facility or reduction in the level of or change in the nature of operations
conducted thereat, any costs or liabilities in connection with off-site disposal
of wastes or hazardous substances, and any actual or potential liabilities to
third parties, including employees, and any related costs and expenses). On the
basis of this review, the Guarantor has reasonably concluded that such
associated liabilities and costs, including the costs of compliance with
Environmental Laws, could not, based upon the facts and circumstances existing
at the time this representation and warranty is made or deemed made, reasonably
be expected to have a Material Adverse Effect.


                                       10
<PAGE>   14
         SECTION 3.07. Taxes. The Guarantor and its Significant Subsidiaries
have filed all material tax returns which are required to be filed by them and
have paid all taxes shown on such returns or pursuant to any assessment received
by the Guarantor or any Subsidiary, except those assessments which are being
contested in good faith by appropriate proceedings. The charges, accruals and
reserves on the books of the Guarantor and its Subsidiaries in respect of taxes
or other governmental charges are, in the opinion of the Guarantor, adequate.

         SECTION 3.08. Subsidiaries. Each of the Guarantor's corporate
Consolidated Subsidiaries is a corporation duly incorporated, validly existing
and in good standing under the laws of its jurisdiction of incorporation, except
where the failure to be so incorporated, existing or in good standing could not,
based upon the facts and circumstances existing at the time this representation
and warranty is made or deemed made, reasonably be expected to have a Material
Adverse Effect. Each such Subsidiary has all corporate powers and all Consents
required to carry on its business as now conducted, other than those powers and
Consents, the failure of which to be possessed or obtained could not, based upon
the facts and circumstances in existence at the time this representation and
warranty is made or deemed made, reasonably be expected to have a Material
Adverse Effect.

         SECTION 3.09. Not an Investment Company. The Guarantor is not an
"investment company" within the meaning of the Investment Company Act of 1940,
as amended.

         SECTION 3.10. Full Disclosure. All information heretofore furnished by
or on behalf of the Guarantor to the Agent in connection with this Agreement,
does not contain any untrue statement of material fact or omit to state any
material fact necessary to make the statements contained herein or therein, in
light of the circumstances under which they were made, not misleading.

         SECTION 3.11. Obligations to be Pari Passu. The Guarantor's obligations
under this Agreement rank pari passu as to priority of payment and in all other
respects with all other unsecured and unsubordinated obligations of the
Guarantor.

                                    ARTICLE 4

types (including, without limitation, loss or damage, product liability,

and in such amounts as is customary in the case of similarly situated
corporations of established reputations engaged in the same or a similar

the case of either the failure of the Guarantor to comply with subclause (b) (y)
of this Section 4.04 or the failure of a Subsidiary to comply with clauses (a)

laws, ordinances, rules, regulations, and requirements of governmental

available to a Recipient, on a non-confidential basis, from a source other than
the Guarantor or any of its Subsidiaries (or any of their respective
representatives or agents) or any Recipient, which source, to the knowledge of
the Recipient, is not prohibited from disclosing such information by a
confidentiality agreement with, or other legal or fiduciary obligation to, the
Guarantor or its Subsidiaries.

         The restrictions set forth in the immediately preceding paragraph shall
not prevent the disclosure by a Recipient of any such information:

              than five business days prior notice (or such shorter period as
              may, in the good faith discretion of the Recipient, be reasonable
              under the circumstances or may be required by any court or agency
              under the circumstances), specifying the


                                       15

              Guarantor an opportunity to seek an appropriate protective order.

         Each Recipient shall agree that, in addition to all other remedies
available, the Guarantor shall be entitled to specific performance and
injunctive and other equitable relief as a remedy for any breach of this Section
4.06(c) by such Recipient.

         SECTION 4.07. Debt. Consolidated Debt will at no time exceed (x) prior
to March 31, 1999, 62% and (y) on and after March 31, 1999, 52.5% of
Consolidated Total Capitalization. For purposes of this Section any preferred
stock of a Consolidated Subsidiary held by a Person other than the Guarantor or

either Credit Agreement) securing Debt outstanding on the Effective Date;

         (b) any Lien existing on any asset of, or capital stock of, or other

event;

         (c) any Lien on any asset securing the payment of all or part of the
purchase price of such asset upon the acquisition thereof by the Guarantor or a
Subsidiary or securing Debt (including any obligation as lessee incurred under a
capital lease) incurred or assumed by the Guarantor or a Subsidiary prior to, at
the time of or within one year after such acquisition (or in the case of real
property, the completion of construction (including any improvements on an
existing property) or the commencement of full operation of such asset or
property, whichever is later), which Debt is incurred or assumed for the purpose
of financing all or part of the cost of acquiring such asset or, in the case of
real property, construction or improvements thereon; provided, that in the case
of any such acquisition, construction or improvement, the Lien shall not apply
to any asset theretofore owned by the Guarantor or a Subsidiary, other than
assets so acquired, constructed or improved;

         (d) any Lien existing on any asset or Stock of any Person at the time
such Person is merged or consolidated with or into the Guarantor or a Subsidiary
which Lien was not created in contemplation of such event;


                                       16
<PAGE>   20
         (e) any Lien existing on any asset or Stock of any Person at the time
of acquisition thereof by the Guarantor or a Subsidiary, which Lien was not
created in contemplation of such acquisition;

         (f) any Lien arising out of the refinancing of any Debt secured by any

provided the principal amount of Debt is not increased and is not secured by any
additional assets, except as provided in the last sentence of this Section 4.08;

Wholly-Owned Consolidated Subsidiary;

         (h) any Lien created pursuant to a Permitted Receivables Transaction;

         (i) any Lien in favor of any country (or any department, agency,

arising in connection with partial, progress, advance or other payments pursuant
to any contract, statute, rule or regulation or securing obligations incurred
for the purpose of financing all or any part of the purchase price (including
the cost of installation thereof or, in the case of real property, the cost of
construction or improvement or installation of personal property thereon) of the
asset subject to such Lien (including, but not limited to, any Lien incurred in
connection with pollution control, industrial revenue or similar financings);

         (j) Liens arising in the ordinary course of its business which (i) do
not secure Debt, (ii) do not secure any single obligation in an amount exceeding
$50,000,000 and (iii) do not in the aggregate materially detract from the value
of its assets or materially impair the use thereof in the operation of its
business; and

         (k) Liens not otherwise permitted by the foregoing clauses (a) through
(j) of this Section 4.08 securing Debt (without duplication) in an aggregate
principal amount at any time outstanding not to exceed an amount equal to the
greater of (i) $300,000,000 or (ii) 10% of Consolidated Tangible Net Worth.

It is understood that any Lien permitted to exist on any asset pursuant to the
foregoing provisions of this Section 4.08 may attach to the proceeds of such
asset and, with respect to Liens permitted pursuant to subsections (a), (b),
(d), (e), (f) (but only with respect to the refinancing of a Debt secured by a
Lien permitted pursuant to subsections (a), (b), (d) or (e)) or (g) of this
Section 4.08, may attach to an asset acquired in the ordinary course of business
as a replacement of such former asset.

         SECTION 4.09. Consolidations, Mergers and Sales of Assets. (a) The
Guarantor will not (i) consolidate or merge with or into any other Person or

              corporation;

                  (B) the Person (if other than the Guarantor) formed by such
              consolidation or into which the Guarantor is merged, or the Person
              which acquires by sale or other transfer, or which leases, all or
              substantially all of the assets of the Guarantor (any such Person,
              the "Successor"), shall be organized and existing under the laws
              of Bermuda or of the United States, any state thereof or the
              District of Columbia and shall expressly assume, in a writing
              executed and delivered to the Agent for delivery to each of the
              Banks, in form reasonably satisfactory to the Agent, the due and
              punctual payment of the principal of and interest on the
              Promissory Notes and the performance of the other obligations
              under this Agreement and the Promissory Notes on the part of the
              Guarantor to be performed or observed, as fully as if such
              Successor were originally named as the Guarantor in this
              Agreement;

                  (C) immediately after giving effect to such transaction, no
              Guarantor Default shall have occurred and be continuing; and

                  (D) the Guarantor has delivered to the Agent a certificate on
              behalf of the Guarantor signed by a Responsible Officer and an
              opinion of counsel, each stating that all conditions provided in
              this Section 4.09 relating to such transaction have been
              satisfied.

         The foregoing provisions of this Section 4.09 shall not restrict the
merger or consolidation of any Subsidiary with and into the Guarantor.

         SECTION 4.10. Transactions with Affiliates. The Guarantor will not, and
will not permit any Subsidiary to, directly or indirectly, pay any funds to or
for the account of, make any investment (whether by acquisition of stock or
indebtedness, by loan, advance, transfer of property, guarantee or other
agreement to pay, purchase or service, directly or indirectly, any Debt, or
otherwise) in, lease, sell, transfer or otherwise dispose of any assets,
tangible or intangible, to, or participate in, or effect any transaction in
connection with any joint enterprise or other joint arrangement with, any
Affiliate (collectively, "AFFILIATE TRANSACTIONS"); provided, however, that the
foregoing provisions of this Section 4.10 shall not prohibit the Guarantor or
any of its Subsidiaries from (a) making Restricted Payments (including, for this
purpose, transactions expressly excluded from the definition of a Restricted
Payment) permitted by Section 4.11, (b) making sales to or purchases from any
Affiliate and, in connection therewith, extending credit or making payments, or
from making payments for services rendered by any Affiliate, if such sales or
purchases are made or such services are rendered in the ordinary course of
business and on terms and conditions at least as favorable to the Guarantor or
such Subsidiary as the terms and conditions which the Guarantor would reasonably
expect to be obtained in a similar transaction with a Person which is not an
Affiliate at such time, (c) making payments of principal, interest and premium
on any Debt of the Guarantor or such Subsidiary held by an


                                       18
<PAGE>   22
Affiliate if the terms of such Debt are at least as favorable to the Guarantor
or such Subsidiary as the terms which the Guarantor would reasonably expect to
have been obtained at the time of the creation of such Debt from a lender which
was not an Affiliate, (d) participating in, or effecting any transaction in
connection with, any joint enterprise or other joint arrangement with any
Affiliate if the Guarantor or such Subsidiary participates in the ordinary
course of its business and on a basis no less advantageous than the basis on
which such Affiliate participates, (e) paying or granting reasonable
compensation and benefits to any director, officer, employee or agent of the
Guarantor or any Subsidiary, (f) paying reasonable legal fees and expenses to a
law firm of which an Affiliate is a member or (g) engaging in any Affiliate
Transaction not otherwise addressed in subsections (a) - (f) of this Section
4.10, the terms of which are not less favorable to the Guarantor or such
Subsidiary than those that the Guarantor would reasonably expect to be obtained
in a comparable transaction at such time with a Person which is not an
Affiliate.

         SECTION 4.11. Restricted Payments. Neither the Guarantor nor any
Subsidiary will declare or make any Restricted Payment unless, after giving
effect thereto, the aggregate of all Restricted Payments declared or made
subsequent to the date hereof does not exceed an amount equal to the sum of (a)
$1,250,000,000 plus (b) 50% of Consolidated Net Income (or minus 100% of
Consolidated Net Income, in the event of a net loss for such period) for the
period from October 1, 1997 through the end of the then most recently ended
fiscal quarter of the Guarantor (treated for this purpose as a single accounting
period), plus (c) the aggregate cash proceeds (net of underwriting commissions)
received by the Guarantor (other than from a Subsidiary) from the issuance or
sale after September 30, 1997 of capital stock or Stock Equivalents of the
Guarantor (other than the proceeds of any capital stock or Stock Equivalent
which by its terms is subject to redemption otherwise than at the sole option of
the Guarantor). Nothing in this Section 4.11 shall prohibit the payment of any
dividend or distribution within 60 days after the declaration thereof if such
declaration was not prohibited by this Section 4.11.

         SECTION 4.12. Prepayment of Existing Agreements. Promptly and in any
event within five Euro-Dollar Business Days (as defined in either Credit
Agreement) of the receipt by the Guarantor or any of its Consolidated
Subsidiaries of net cash proceeds from the issuance of long-term debt securities
or equity securities in the capital markets, the Guarantor will cause Tyco US
(as defined in either Credit Agreement) to prepay loans outstanding under the
Existing Agreements (as defined in either Credit Agreement) in an aggregate
amount equal to the largest multiple of $1,000,000 which does not exceed the
amount of such net cash proceeds, and simultaneously with such prepayment to
reduce the commitments under the Existing Agreements by an equal amount.

                                      TAXES

         SECTION 6.01. Withholding Taxes. Each payment by the Guarantor
hereunder to or for the account of any Bank (a "Payment") shall be made without
any deduction or withholding for any Bank Foreign Taxes with respect to such
Bank; provided that if the Guarantor shall be required by law to make any such
deduction or withholding from any Payment, the Guarantor will:

                (i)   pay such amounts in addition to such Payment as may be

         taxation or other authorities within the time allowed under applicable
         law; and

                (iii) furnish within 45 days thereafter to the Agent, the

Foreign Taxes imposed (otherwise than by deduction or withholding) on any Bank
which constitute Bank Foreign Taxes with respect to such Bank and (ii) all Bank

Foreign Taxes or Bank Domestic Taxes to be paid by the Guarantor pursuant to

Taxes shall have been correctly or legally imposed, reimburse such Bank
therefor, together with any interest, penalties and expenses in connection
therewith, plus interest thereof at the rate specified in the first sentence of
Section 2.07(a) of each Credit Agreement. To the extent that any Bank which is
reimbursed by the Guarantor as provided in this Section thereafter receives any
payment allocated to Bank Foreign Taxes or Bank Domestic Taxes in respect of
which such Bank was so reimbursed from a governmental taxing authority because
such Bank Foreign Taxes or Bank Domestic Taxes were incorrectly or illegally
imposed, such Bank shall return to the Guarantor (without interest) any such
payment.

forth on the signature pages hereof or such other address or facsimile or telex
number as such party may hereafter specify for the purpose by notice to the
other party. Each such notice, request or other communication shall be effective
(i) if given by telex, when such telex is transmitted to the telex number
specified in this Section and the appropriate answerback is received, (ii) if
given by facsimile, when such facsimile is transmitted to the facsimile number
specified on the signature pages hereof and electronic, telephonic or other
appropriate confirmation of receipt is received by the sender, (iii) if given by
mail, 72 hours after such communication is deposited in the mails with first
class postage prepaid, addressed as aforesaid or (iv) if given by any other
means, when delivered at the address specified on the signature pages hereof.

         SECTION 7.02. No Waivers. No failure or delay by the Agent or any Bank
in exercising any right, power or privilege hereunder or under any other
Financing Document shall operate as a waiver thereof nor shall any single or
partial exercise thereof preclude any other or further exercise thereof or the
exercise of any other right, power or privilege. The rights and remedies herein
and therein provided shall be cumulative and not exclusive of any rights or
remedies provided by law.


                                       23

         SECTION 7.03. Expenses; Indemnification. (a) The Guarantor shall pay
(i) all reasonable out-of-pocket expenses of the Agent, including reasonable
fees and disbursements of special counsel for the Agent, in connection with the
preparation and administration of this Agreement, any waiver or consent
hereunder or any amendment thereof or any default or alleged default hereunder
and (ii) if an Event of Default (as defined in any Credit Agreement) occurs, all
reasonable out-of-pocket expenses incurred by the Agent and each Bank, including
reasonable fees and disbursements of counsel, in connection with such Event of
Default and collection, bankruptcy, insolvency and other enforcement proceedings
in respect of this Agreement resulting therefrom.

         (b) The Guarantor agrees to indemnify the Agent and each Bank, their
respective Affiliates and the respective directors, officers, agents and
employees of the foregoing (each an "Indemnitee") and hold each Indemnitee
harmless from and against any and all liabilities, losses, damages, costs and
expenses, including, without limitation, the reasonable fees and disbursements
of counsel, which may be incurred by such Indemnitee (whether or not such
Indemnitee shall be designated a party thereto) arising out of any
investigative, administrative or judicial proceeding (brought or threatened)
relating to or arising out of this Agreement, the arrangement, administration,
performance or enforcement thereof; provided that no Indemnitee shall have the
right to be indemnified hereunder for such Indemnitee's own gross negligence or
willful misconduct as determined by a court of competent jurisdiction; provided
further that no Indemnitee shall have the right to be indemnified hereunder in
connection with any proceedings between it and another Indemnitee which does not
relate to the Guarantor.

         (c) If any proceeding or claim shall be brought or asserted against any
Indemnitee in respect of which indemnity may be sought pursuant to the preceding
subsection, such Indemnitee shall promptly notify the Guarantor. The Guarantor
shall not be liable for any costs or expenses in connection with any settlement
entered into without its consent.

         SECTION 7.04. Judicial Proceedings. (a) Consent to Jurisdiction. The
Guarantor irrevocably submits to the non-exclusive jurisdiction of any federal
or New York State court sitting in New York City over any suit, action or
proceeding arising out of or relating to this Agreement. The Guarantor
irrevocably waives, to the fullest extent permitted by law, any objection which
it may now or hereafter have to the laying of the venue of any such suit, action
or proceeding brought in such court and any claim that any suit, action or
proceeding brought in such court has been brought in an inconvenient forum. The
Guarantor agrees that a final judgment in any such suit, action or proceeding
brought in such a court shall be conclusive and binding upon it and will be
given effect in Bermuda to the fullest extent permitted by applicable law and
may be enforced in any federal or New York State court sitting in New York City
(or any other courts to the jurisdiction of which the Guarantor is or may be
subject) by a suit upon such judgment, provided that service of process is
effected upon it in one of the manners specified herein or as otherwise
permitted by law.


                                       24
<PAGE>   28
         (b) Appointment of Agent for Service of Process. The Guarantor hereby
irrevocably designates and appoints CT Corporation System having an office on
the date hereof at 1633 Broadway, New York, New York 10019 as its authorized
agent, to accept and acknowledge on its behalf, service or any and all process
which may be served in any suit, action or proceeding of the nature referred to
in subsection (a) above in any federal or New York State court sitting in New
York City. The Guarantor represents and warrants that such agent has agreed in
writing to accept such appointment and that a true copy of such designation and
acceptance has been delivered to the Agent. Such designation and appointment
shall be irrevocable until all principal and interest and all other amounts
payable hereunder shall have been paid in full in accordance with the provisions
hereof. If such agent shall cease so to act, the Guarantor covenants and agrees
to designate irrevocably and appoint without delay another such agent
satisfactory to the Agent and to deliver promptly to the Agent evidence in
writing of such other agent's acceptance of such appointment.

         (c) Service of Process. The Guarantor hereby consents to process being
served in any suit, action, or proceeding of the nature referred to in
subsection (a) above in any federal or New York State court sitting in New York
City by service of process upon the agent of the Guarantor, as the case may be,
for service of process in such jurisdiction appointed as provided in subsection
(b) above; provided that, to the extent lawful and possible, written notice of
said service upon such agent shall be mailed by registered airmail, postage
prepaid, return receipt requested, to the Guarantor at its address specified on
the signature pages hereof or to any other address of which the Guarantor shall
have given written notice to the Agent. The Guarantor irrevocably waives, to the
fullest extent permitted by law, all claim of error by reason of any such
service and agrees that such service shall be deemed in every respect effective
service of process upon the Guarantor in any such suit, action or proceeding and
shall, to the fullest extent permitted by law, be taken and held to be valid and
personal service upon and personal delivery to the Guarantor.

         (d) No Limitation on Service or Suit. Nothing in this Section 7.04
shall affect the right of the Agent or any Bank to serve process in any other
manner permitted by law or limit the right of the Agent or any Bank to bring
proceeding against the Guarantor in the courts of any jurisdiction or
jurisdictions.

         SECTION 7.05. Judgment Currency. If, under any applicable law and
whether pursuant to a judgment being made or registered against the Guarantor or
for any other reason, any payment under or in connection with this Agreement, is
made or satisfied in a currency (the "Other Currency") other than that in which
the relevant payment is due (the "Required Currency") then, to the extent that
the payment (when converted into the Required Currency at the rate of exchange
on the date of payment or, if it is not practicable for the party entitled
thereto (the "Payee") to purchase the Required Currency with the other Currency
on the date of payment, at the rate of exchange as soon thereafter as it is
practicable for it to do so) actually received by the Payee falls short of the
amount due under the terms of this Agreement, the Guarantor shall, to the extent
permitted by law, as a separate and independent obligation, indemnify and hold
harmless the Payee against the amount of such short-fall. For the purpose of
this Section, "rate of


                                       25
<PAGE>   29
exchange" means the rate at which the Payee is able on the relevant date to
purchase the Required Currency with the Other Currency and shall take into
account any premium and other costs of exchange.

         SECTION 7.06. Amendments and Waivers. Any provision of this Agreement
or the Promissory Notes may be amended or waived if, but only if, such amendment
or waiver is in writing and is signed by the Guarantor and the Agent with the
prior written consent of the Required Banks under (and as defined in) each of
the Credit Agreements.

         SECTION 7.07. Successors and Assigns. (a) The provisions of this
Agreement shall be binding upon the Guarantor and its successors and shall inure
to the benefit of the Agent and the Banks and their respective successors and
assigns.

         SECTION 7.08. GOVERNING LAW. THIS AGREEMENT SHALL BE GOVERNED BY AND
CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK.

         SECTION 7.09. Counterparts. This Agreement may be signed in any number
of counterparts, each of which shall be an original, with the same effect as if
the signatures thereto and hereto were upon the same instrument.

         SECTION 7.10. No Seal. As contemplated by the Bye-Laws of the
Guarantor, this Agreement shall not be required to be issued under the seal of
the Guarantor.

         SECTION 7.11. WAIVER OF JURY TRIAL. EACH OF THE GUARANTOR AND THE AGENT
HEREBY IRREVOCABLY WAIVES ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL
PROCEEDING ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS
CONTEMPLATED HEREBY.

         SECTION 7.12. Amendment of Existing Parent Guarantee Agreement. The
Guarantor hereby agrees to the amendments specified in Section 3.02(c) of each
of the Credit Agreements.
