1. DESCRIPTION OF PLAN

GENERAL

In connection with the 2003 acquisition of Solidstate Controls, Inc. by AMETEK,
Inc. ("AMETEK" or "the Company") from the Marmon Group, AMETEK became the plan
sponsor of the Solidstate Controls, Inc. Hourly Employees' (CWA) Retirement Plan
("the Plan"). The following brief description of the Plan provides only
summarized information. Participants should refer to the Plan document for a
more complete description of the Plan's provisions.

The Plan is a tax-deferred 401(k) defined contribution savings plan which
provides eligible employees (whose employment is governed by the terms of a
collective bargaining agreement with the Communications Workers of America
(CWA)) of Solidstate Controls, Inc., an opportunity to invest a portion of their
compensation, as defined by the Plan, in one or a combination of investment
programs (see Note 3).

CONTRIBUTIONS

Each year, participants have an opportunity to invest up to 16% (maximum 6%
before tax and maximum 10% after tax) of their annual compensation, as defined
by the Plan, in multiples of one percent, except for certain highly compensated
participants who may be subject to certain regulatory limitations. Participants
may also contribute amounts representing rollovers from other qualified plans.
The Plan provides for Company contributions equal to 40% of the amount
contributed by each participant, up to a maximum percentage ranging from 1% to
6% of the participants' compensation as determined by the terms of the
collective bargaining agreement. Retirement and matching company contributions
are paid to the Plan at anytime prior to the due date prescribed by law for
filing the Company's federal income tax return for that Plan year.

The Plan has a retirement feature for eligible participants, AMETEK makes
contributions to the Plan on behalf of such participants at a rate $0.35 for
each hour that an active participants is paid compensation. Participant
contributions under the retirement feature of the Plan are not permitted.
Investment programs and transfer and exchange privileges available under the
retirement feature of the Plan are the same as the savings feature under the
Plan.

Forfeited Company contributions, which are insignificant in amount, are used to
reduce current-year Company contributions.

                                  (Unaudited)

1. DESCRIPTION OF PLAN (CONTINUED)

PARTICIPANT ACCOUNTS

Each participant's account is credited with the participant's contributions and
allocations of (a) the Company's contributions and (b) Plan net earnings.
Allocations are based on participant earnings and/or account balances, as
defined. The benefit to which a participant is entitled is the balance in the
participant's account.

VESTING

Participants are fully vested at all times in their contributions to the Plan.
Company contributions under the savings provisions of the Plan and under the
retirement feature of the Plan become fully vested after five years of service.


PAYMENT OF BENEFITS

On termination of service, death, disability or retirement, a participant may
receive a lump-sum amount equal to his or her vested account, elect to receive
payment in installments for life, subject to certain restrictions based on life
expectancy or direct rollover to eligible retirement plan. Participants with a
vested account value of less than $5,000 will be paid in a lump sum as soon as
practicable after retirement, termination, disability or death of the
participant. When a participant attains age 59-1/2 while still an employee, he
or she can elect to withdraw a specified portion of his or her vested account
balance. Also, in certain cases of financial hardship, a participant may elect
to withdraw up to a specified portion of his or her vested account balance,
regardless of age.

PLAN TERMINATION

The Plan is subject to the provisions of the Employee Retirement Income Security
Act of 1974 ("ERISA"). While the Company has not expressed any intent to
terminate the Plan, it is free to do so at any time subject to the provisions of
ERISA, and applicable labor agreements. In the event of Plan termination, each
participant will receive the value of his or her separate vested account.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

BASIS OF FINANCIAL STATEMENTS AND PRESENTATION FORMAT

The accompanying financial statements are unaudited because the number of
participants in the Plan are fewer than the number of participants which would
require audited financial statements under ERISA. The financial statements
presented are for a partial year in 2003 due to the 2003 acquisition by AMETEK
mentioned in Note 1. The accompanying financial statements have been prepared on
the accrual basis of accounting, except for the non-accrual of a liability for
amounts owed to withdrawing participants, which are reflected in plan equity in
accordance with U.S. generally accepted accounting principles (see Note 6). The
accompanying financial statements have been prepared in accordance with
Statement of Position (SOP) 99-3, "Accounting for and Reporting of Certain
Defined Contribution Benefit Plan Investments and Other Disclosure Matters."

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

USE OF ESTIMATES

The preparation of financial statements in conformity with U.S. generally
accepted accounting principles requires management to make estimates and
assumptions that affect amounts reported in the financial statements and
accompanying notes. Actual results could differ from those estimates and
assumptions.

RISKS AND UNCERTAINTIES

The Plan invests in various investment securities. Investment securities are
exposed to various risks such as interest rate, market and credit risks. Due to
the level of risk associated with certain investment securities, it is at least
reasonably possible that changes in the values of investment securities will
occur in the near term and that such changes could materially affect
participants' account balances and the amounts reported in the statements of net
assets available for benefits.

INVESTMENT VALUATION AND INCOME RECOGNITION

The shares of registered investment companies are valued at quoted market
prices, which represent the net asset values of shares held by the Plan at
year-end. The fair value of the participation units in the common/collective
trust is based on quoted redemption values on the last business day of the plan
year. Money market and short-term investments are carried at the fair value
established by the issuer and/or the trustee. The participant loans are valued
at their outstanding balances, which approximates fair value.

Purchases and sales of investments are reflected on trade dates. Realized gains
and losses on sales of investments are based on the average cost of such
investments. Interest income is recorded on the accrual basis. Dividend income
is recorded on the ex-dividend date. Income from other investments is recorded
as earned.

The net appreciation of investments represents the sum of the change in the
difference between year-end market value and cost of investments, and the
difference between the proceeds received and the cost of investments sold during
the year.

4. INCOME TAX STATUS

The Plan has received a determination letter from the Internal Revenue Service
dated November 1, 2002, stating that the Plan is qualified under Section 401(a)
of the Internal Revenue Code (the "Code") and, therefore, the related trust is
exempt from taxation. Subsequent to this issuance of the determination letter,
the Plan was amended and restated. Once qualified, the Plan is required to
operate in conformity with the Code to maintain its qualification. The plan
administrator believes the Plan is being operated in compliance with the
applicable requirements of the Code and, therefore, believes that the Plan, as
amended and restated, continues to be qualified and the related trust is tax
exempt.
