2 Report of Independent Auditors The Administrative Committee AMETEK Retirement and Savings Plan We have audited the accompanying statements of financial condition of the AMETEK Retirement and Savings Plan as of December 31, 1999 and 1998, and the related statements of income and changes in plan equity for each of the three years in the period ended December 31, 1999. These financial statements are the responsibility of the Plan's management. Our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits in accordance with auditing standards generally accepted in the United States. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion. In our opinion, the financial statements referred to above present fairly, in all material respects, the financial condition of the AMETEK Retirement and Savings Plan at December 31, 1999 and 1998, and the income and changes in plan equity for each of the three years in the period ended December 31, 1999, in conformity with accounting principles generally accepted in the United States. /s/ Ernst & Young LLP Philadelphia, Pennsylvania June 7, 2000 F-1

8 THE AMETEK RETIREMENT AND SAVINGS PLAN NOTES TO FINANCIAL STATEMENTS DECEMBER 31, 1999 1. DESCRIPTION OF THE PLAN The following brief description of the AMETEK Retirement and Savings Plan ("the Plan") provides only summarized information. Participants should refer to the full Summary Plan Description for more complete information. The Plan is a tax-deferred 401(k) defined contribution savings plan, with a separate retirement feature described below, which provides eligible employees of AMETEK, Inc. ("AMETEK", or "the Company"), and certain of its subsidiaries, an opportunity to invest up to 14% of their compensation in one or a combination of investment programs (described in Note 3). Participants are fully vested at all times in their contributions to the Plan and are vested in Company contributions after three years of service, or upon death, attainment of age 65 or early, normal or disability retirement. Forfeited Company contributions, which are insignificant in amount, are used to reduce current-year Company contributions. If a participant terminates employment with the Company for any reason, he or she may receive a distribution following termination of employment or may elect to commence distributions at, or after age 55, but no later than age 70-1/2. When a participant attains age 59-1/2 while still an employee, he or she can elect to withdraw the vested amount of his or her 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. The Plan also allows participants to borrow funds from their accounts, subject to a charge for administrative fees (beginning in 1998), and other certain limitations, and such amounts are reflected in a loan account receivable until repaid by the participant (see Note 4). The Plan provides for Company contributions equal to 33 1/3% of the first 6% of compensation contributed by each participant, to a maximum annual contribution of $1,200 per participant. Matching Company contributions are credited to participants' accounts at the same time their contributed compensation is invested. Effective January 1, 1997, the Plan was amended and restated to incorporate a retirement feature into the Plan to benefit eligible salaried and hourly employees hired by AMETEK after December 31, 1996. Commencing with the January 1, 1997 effective date, AMETEK makes contributions to the Plan on behalf of such employees equal to a specified percentage of their compensation earned based upon each participant's age and years of service, up to predetermined limits. Employee contributions under the retirement feature of the Plan are not permitted. Investment programs and transfer and exchange privileges available under the retirement feature are the same as for the savings feature under the Plan. However, retirement feature contributions become fully vested after five years of service, and loans and withdrawals are not permitted. 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 the Employee Retirement Income Security Act of 1974 as amended ("ERISA"), and applicable labor agreements. In the event of termination, each participant will receive the value of his or her separate account. Participants' collective accounts are represented by the Plan's equity as shown in the accompanying financial statements. 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Basis of financial statements 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 former participants, which are reflected in plan equity in accordance with accounting principles generally accepted in the United States. (see Note 8). 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. Dividend income is recorded on the ex-dividend date. Income from other investments is recorded as earned. Use of estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States 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. Investment valuation Investments in equity securities are carried at market value based upon closing market quotes 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. Life Insurance Contracts are carried at the cash surrender value of such policies at year-end. F-7

9 THE AMETEK RETIREMENT AND SAVINGS PLAN NOTES TO FINANCIAL STATEMENTS DECEMBER 31, 1999 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (continued) Guaranteed Investment Contracts ("GICs"), all of which are considered benefit-responsive, are reported at contract value, which approximates fair value. Fully benefit-responsive investment contracts are contracts that transfer financial risk of principal and interest to a responsible third party, and provide for participant-initiated transactions without conditions, limitations or restrictions. All other investment contracts are reported at fair value. 3. INVESTMENT PROGRAMS At December 31, 1999, the Vanguard Fiduciary Trust Company was the Trustee of the Plan. Each participant may have his or her accounts invested (up to certain specified limits) in one or a combination of the following investment programs as of December 31, 1999: (a) The Fixed Income Funds: The Fixed Income Funds are comprised of a retirement savings trust which invests in a diversified portfolio of GICs issued by insurance companies and other financial institutions. Contributions to the retirement savings trust and proceeds from its GIC maturities are invested entirely in the Vanguard Stable Value Market Fund, which invests in a more diversified GIC portfolio. The Fixed Income Fund also holds investments in two additional Vanguard Funds: a Bond Market Index Fund and a Prime Money Market Fund. Investments of the Fixed Income Fund (carried at fair value) are shown in the table below: Balance at December 31, --------------------------- 1999 1998 ---- ---- GICs (1)* $42,785,829 $43,828,547 ----------- ---------- Other: Money Market Mutual Fund 6,252,921 4,478,679 Vanguard Total Bond Market Index Fund (cost $1,356,410) 1,281,910 1,199,811 ----------- ----------- 7,534,831 5,678,490 ----------- ----------- Total Fixed Income Fund investments $50,320,660 $49,507,037 =========== =========== *At December 31, investment represents 5% or more of the fair value of the Plan's net assets. (1) Includes synthetic investment contracts in which a financially responsible third party pays a contract rate of interest on the underlying investments, and provides for full payment of principal upon participant-directed withdrawals from the Trust. Also includes a short-term investment account utilized for withdrawals, transfers, and future GIC purchases. Income on the GICs is earned based on interest rates ranging from 5.3% to 6.8% for the year ended December 31, 1999 and 5.4% to 6.8% for the year ended December 31, 1998. Variable-rate contracts are reset quarterly, but will not fall below zero. Contracts with fixed rates of interest through maturity ranged between 5.9% and 6.2% for each of the Plan years ended December 31, 1999 and 1998, respectively. The weighted average crediting interest rate for GICs was 6.3% for 1999 and 6.2% for 1998. The average yield for all investments within the Fixed Income Fund was 5.7% and 6.2% for the Plan years ended December 31, 1999 and 1998, respectively, net of investment expenses. F-8

10 THE AMETEK RETIREMENT AND SAVINGS PLAN NOTES TO FINANCIAL STATEMENTS DECEMBER 31, 1999 3. INVESTMENT PROGRAMS (continued) (b) The Balanced Funds: Participants investing in the Balanced Funds have two alternatives for allocating their accounts: 1. Vanguard LifeStrategy Growth Funds - Participants may select among three growth strategies (Conservative Growth, Moderate Growth, and Aggressive Growth), each with corresponding levels of asset allocations and investment risks. Each portfolio invests in various mutual funds within the Vanguard Group with fund objectives meeting the overall strategy chosen by the participant. 2.

12 THE AMETEK RETIREMENT AND SAVINGS PLAN NOTES TO FINANCIAL STATEMENTS DECEMBER 31, 1999 3. INVESTMENT PROGRAMS (continued) A participant may change his or her contribution percentage election to any fund effective as of the first day of each calendar quarter. In addition, the plan provides for participant-directed investing, whereby participants may change their investment selection within or between investment programs or specific investment funds in which their contributions are invested at any time, subject to certain limitations. The Plan also permits a participant, at any time, to completely discontinue contributions on a prospective basis. There were approximately 5,000 participants in the Plan at December 31, 1999. Participants generally invest in more than one fund. 4. LOAN ACCOUNTS RECEIVABLE Participants may borrow a minimum of $1,000 or up to a maximum equal to the lesser of $50,000 or 50% of their vested account balance. Participants may have up to two outstanding loans at any time, the sum of which may not exceed the maximum. Repayment terms of the loan are generally limited to no longer than 60 months from inception. The loans are secured by the balance in the participant's account, and bear interest at rates established by the Plan's administrative committee, which approximate rates charged by commercial lending institutions for comparable loans. Interest rates on loans outstanding at December 31, 1999 ranged between 7% and 10%. 5.

Under the Plan, contributions will not be taxed to the employee until a distribution from the Plan is made. However, participants who have invested in insurance contracts are subject to ordinary income tax annually on the premiums paid for the life insurance coverage. 7.
