NOTE 4--COMMITMENTS AND CONTINGENCIES

     In the course of pursuing its normal business activities, the Company is
involved in various legal proceedings and claims. Management does not expect
that amounts, if any, which may be required to be paid by reason of such
proceedings or claims will have a material effect on the Company's financial
position or results of operations.

     Subsequent to the acquisition of Amphenol from Allied Signal Corporation in
1987 (Allied Signal merged with Honeywell International Inc. in December 1999
("Honeywell")), Amphenol and Honeywell have been named jointly and severally
liable as potentially responsible parties in relation to several environmental
cleanup sites. Amphenol and Honeywell have jointly consented to perform certain
investigations and remedial and monitoring activities at two sites and they have
been jointly ordered to perform work at another site. The responsibility for
costs incurred relating to these three sites is apportioned between Amphenol and
Honeywell based on an agreement entered into in connection with the acquisition
in 1987. For sites covered by this agreement, to the extent that conditions or
circumstances occurred or existed at the time of or prior to the acquisition,
Honeywell is currently obligated to pay 80% of the costs up to $30,000 and 100%
of the costs in excess of $30,000. At March 31, 2002, approximately $27,400 of
costs have been incurred applicable to this agreement. Honeywell representatives
work closely with the Company in addressing the most significant environmental
liabilities. Management does not believe that the costs associated with
resolution of these or any other environmental matters will have a material
adverse effect on the Company's financial condition or results of operations.

     A subsidiary of the Company has an agreement with a financial institution
whereby the subsidiary can sell an undivided interest of up to $85,000 in a
designated pool of qualified accounts receivable. The agreement expires in May
2004 with respect to $60,000 of accounts receivable and expires in July 2002
with respect to an additional $25,000 of accounts receivable. Under the terms of
the agreement, new receivables are added to the pool as collections reduce
previously sold accounts receivable. The Company services, administers and
collects the receivables on behalf of the purchaser. Program fees payable to the
purchaser under this agreement are equivalent to rates afforded high quality
commercial paper issuers plus certain administrative expenses and are included
in other expenses, net, in the accompanying Condensed Consolidated Statement of
Income. The agreement contains certain covenants and provides for various events
of termination. In certain circumstances the Company is contingently liable for
the collection of the receivables sold; management believes that its allowance
for doubtful accounts is adequate to absorb the expense of any such liability.
At March 31, 2002 and December 31, 2001, approximately $69,300 and $74,200,
respectively, of receivables were sold under the agreement and are therefore not
reflected in the accounts receivable balance in the accompanying Condensed
Consolidated Balance Sheet.

NOTE 5--NEW ACCOUNTING PRONOUNCEMENTS

     Effective January 1, 2002, the Company adopted Financial Accounting
Standard ("FAS") No. 142, "Goodwill and Other Intangible Assets". The standard
changes the accounting for goodwill and intangible assets with an indefinite
life whereby such assets will no longer be amortized; however, the standard does
require evaluation for impairment and a corresponding writedown, if appropriate.
FAS No. 142 requires an initial evaluation of impairment upon adoption. Such
evaluation was performed as of January 1, 2002 resulting in no impairment in the
value of the Company's goodwill and other intangible assets.

Comparative information as if goodwill had not been amortized in the first
quarter of 2001 is as follows:

     Effective January 1, 2002, the Company adopted FAS No. 143, "Accounting for
Asset Retirement Obligations" and FAS No. 144 " Accounting for the Impairment or
Disposal of Long-Lived Assets". FAS No. 143 addresses the recognition and
remeasurement of obligations associated with the retirement of tangible
long-lived assets. FAS No. 144 addresses accounting and reporting for the
impairment or disposal of long-lived assets, including discontinued operations.
There was no effect to the Company's financial statements as a result of such
adoption.

                      MANAGEMENT'S DISCUSSION AND ANALYSIS
                OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
                  (DOLLARS IN THOUSANDS, EXCEPT PER SHARE DATA)

ITEM 2.    RESULTS OF OPERATIONS

THREE MONTHS ENDED MARCH 31, 2002 COMPARED TO THE THREE MONTHS ENDED MARCH 31,
2001

     Net sales decreased approximately 19% to $255,976 in the first quarter of
2002 compared to sales of $316,672 for the same period in 2001. The decrease is
primarily attributable to decreased sales of interconnect and cable products for
communications markets, and to a lesser extent decreased sales of interconnect
products for industrial applications. Such decreases were partially offset by
increased sales of interconnect products for aerospace and defense applications.
Currency translation had the effect of decreasing sales in the first quarter of
2002 by approximately $5.3 million when compared to exchange rates for the 2001
period.

     The gross profit margin as a percentage of net sales (including
depreciation in cost of sales) was 30% for the first quarter of 2002 compared to
34% for the 2001 period. The decrease in gross margin is generally attributable
to the adverse effects of lower sales volume and a difficult pricing
environment, particularly in communications markets, partially offset by cost
reduction activities.

     Selling, general and administrative expenses as a percentage of net sales
remained constant at approximately 14% for the first quarter 2002 compared to
the 2001 period.

     Goodwill amortization expense was nil in the first quarter 2002 as a result
of adoption of FAS No. 142; whereas goodwill amortization was $3,514 in the
first quarter 2001.

     Interest expense for the first quarter of 2002 was $12,838 compared to
$14,210 for the 2001 period. The decrease is attributable to lower average debt
levels and lower interest rates.

     The provision for income taxes for the first quarter of 2002 was at an
effective rate of 35% compared to 37% in the 2001 period. For the first quarter
2001, the effective tax rate, excluding non-deductible goodwill amortization,
was 35%.

LIQUIDITY AND CAPITAL RESOURCES

     Cash provided by operating activities was $43,635 in the first quarter of
2002 compared to $37,254 in the 2001 period. The increase in cash flow relates
primarily to a net decrease in non-cash components of working capital offset in
part by a decrease in net income.

     For the first quarter of 2002, cash from operating activities was used to
repay $23,875 in bank debt, and to fund capital expenditures of $4,088, and
acquisitions of $11,950. In addition, cash from operating activities was used to
fund a reduction in sales of receivables of $4,900. In the 2001 period, cash
from operating activities and borrowings under the revolving credit facility
were used to fund capital expenditures of $13,907, and acquisitions of $3,523,
and to repay $30,000 of bank debt.

     The Company has a bank loan agreement (Bank Agreement) which includes a
Term Loan, encompassing a Tranche A and B, and a $150 million revolving credit
facility. At March 31, 2002 the Tranche A had a balance of $237.7 million and
matures over the period 2002 to 2004, and the Tranche B had a balance of $284.5
million and matures over the period 2005 and 2006. The revolving credit facility
expires in 2004; availability under the facility at March 31, 2002 was $142.3
million, after reduction of

                                       11
<Page>

$7.7 million for outstanding letters of credit. The Bank Agreement is secured by
a first priority pledge of 100% of the capital stock of the Company's direct
domestic subsidiaries and 65% of the capital stock of direct material foreign
subsidiaries, as defined in the Bank Agreement. The Bank Agreement also requires
that the Company satisfy certain financial covenants including interest coverage
and leverage ratio tests, and includes limitations with respect to, among other
things, indebtedness and restricted payments, including dividends on the
Company's common stock.

     The Company has entered into interest rate swap agreements that effectively
fixed the Company's interest cost on $450 million of borrowings under the Bank
Agreement. These agreements expire in 2002.

     The Company's EBITDA, as defined in the Bank Agreement was $49.3 million
and $77.3 million for the three months ended March 31, 2002 and 2001,
respectively. EBITDA is not a defined term under Generally Accepted Accounting
Principles (GAAP) and is not an alternative to operating income or cash flow
from operations as determined under GAAP. The Company believes that EBITDA
provides additional information for determining its ability to meet future debt
service requirements; however, EBITDA does not reflect cash available to fund
cash requirements.

     The Company's primary ongoing cash requirements will be for operating and
capital expenditures, product development activities and debt service. The
Company's debt service requirements consist primarily of principal and interest
on bank borrowings and interest on its 9 7/8% Senior Subordinated Notes due
2007.

     The Company has not paid, and does not have any present intention to
commence payment of, cash dividends on its common stock. The Company expects
that ongoing requirements for operating and capital expenditures, product
development activities and debt service will be funded by internally-generated
cash flow and availability under the Company's revolving credit facility. The
Company may also use cash to fund part or all of the cost of future
acquisitions.

ENVIRONMENTAL MATTERS

     Subsequent to the acquisition of Amphenol from Allied Signal Corporation in
1987 (Allied Signal merged with Honeywell International Inc. in December 1999
("Honeywell")), Amphenol and Honeywell have been named jointly and severally
liable as potentially responsible parties in relation to several environmental
cleanup sites. Amphenol and Honeywell have jointly consented to perform certain
investigations and remedial and monitoring activities at two sites and they have
been jointly ordered to perform work at another site. The responsibility for
costs incurred relating to these three sites is apportioned between Amphenol and
Honeywell based on an agreement entered into in connection with the acquisition
in 1987. For sites covered by this agreement, to the extent that conditions or
circumstances occurred or existed at the time of or prior to the acquisition,
Honeywell is currently obligated to pay 80% of the costs up to $30 million and
100% of the costs in excess of $30 million. At March 31, 2002, approximately
$27.4 million of costs have been incurred applicable to this agreement.
Honeywell representatives work closely with the Company in addressing the most
significant environmental liabilities. Management does not believe that the
costs associated with resolution of these or any other environmental matters
will have a material adverse effect on the Company's financial condition or
results of operations.

EURO CURRENCY CONVERSION

     On January 1, 1999, certain member countries of the European Union
established fixed conversion rates between their existing currencies and the
European Union's common currency (the "euro"). The transition period for the
introduction of the euro began on January 1, 1999. Beginning January 1, 2002,
the

                                       12
<Page>

participating countries issued new euro-denominated bills and coins for use in
cash transactions. No later than July 1, 2002, the participating countries will
withdraw all bills and coins denominated in the legacy currencies, so that the
legacy currencies will no longer be legal tender for any transactions, making
the conversion to the euro complete.

     Based on progress to date, the Company believes that the use of the euro
will not have a significant impact on the manner in which it conducts its
business. Accordingly, conversion to the euro is not expected to have a material
effect on the Company's consolidated financial position, consolidated results of
operations, or liquidity.
