2 Report of Independent Auditors The Administrative Committee AMETEK 401(K) Plan for Acquired Businesses We have audited the accompanying statements of financial condition of the AMETEK 401(K) Plan for Acquired Businesses as of December 31, 2000 and 1999, and the related statements of income and changes in plan equity for the year ended December 31, 2000 and the eight month 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 401(K) Plan for Acquired Businesses at December 31, 2000 and 1999, and the income and changes in plan equity for the year ended December 31, 2000 and the eight month period ended December 31, 1999, in conformity with accounting principles generally accepted in the United States. /s/ Ernst & Young LLP Philadelphia, Pennsylvania June 7, 2001 F-1

7 THE AMETEK 401(K) PLAN FOR ACQUIRED BUSINESSES NOTES TO FINANCIAL STATEMENTS DECEMBER 31, 2000 1. DESCRIPTION OF THE PLAN The AMETEK 401(K) Plan for Acquired Businesses ("the Plan") was established on May 1, 1999 for the benefit of eligible employees of businesses acquired by AMETEK, Inc. The following brief description of 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, which provides eligible employees of businesses acquired by AMETEK, Inc. ("AMETEK", or "the Company"), 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 both their contributions to the Plan and in 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, and certain other 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 100% of the amount contributed by each participant, up to a maximum percentage ranging from 2% to 6% of the participants' compensation as determined by the Board of Directors for each business. Matching Company contributions are credited to participants' accounts at the same time their contributed compensation is invested. 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. F-6

8 THE AMETEK 401(K) PLAN FOR ACQUIRED BUSINESSES NOTES TO FINANCIAL STATEMENTS DECEMBER 31, 2000 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, 2000 and 1999, the assets of the Plan were held in a trust administered by the Vanguard Fiduciary Trust Company. 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, 2000: (a) The Fixed Income Funds: The Fixed Income Funds are comprised of the Vanguard 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 Total 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, --------------- 2000 1999 ---- ---- The Vanguard Retirement Savings Trust $1,099,734 $293,530 ---------- -------- Mutual Funds: Vanguard Prime Money Market Fund * 2,589,541 505,362 Vanguard Total Bond Market Index Fund (cost 2000- $817,565 and 1999 - $173,047) 833,464 169,066 ---------- -------- 3,423,005 674,428 ---------- -------- Total Fixed Income Fund investments $4,522,739 $967,958 ========== ======== * At December 31, investment represents 5% or more of the fair value of the Plan's net assets. Income on the GICs is earned at interest rates ranging from 5.1% to 8.2% for the year ended December 31, 2000 and 5.0% to 8.0% for the period ended December 31, 1999. Variable-rate contracts are reset quarterly, but will not fall below zero. Contracts with fixed rates of interest through maturity also ranged between 5.1% and 8.2% for the Plan year ended December 31, 2000 and 5.0% to 8.0% for the period ended December 31, 1999. The weighted average crediting interest rate for the Vanguard Retirement Savings Trust was approximately 6.2% for 2000 and 5.9% for 1999. The average yield for all investments within the Fixed Income Fund was 5.5% for the Plan year ended December 31, 2000 and 4.8% for the eight month period ended December 31, 1999, net of investment expenses.

9 THE AMETEK 401(K) PLAN FOR ACQUIRED BUSINESSES NOTES TO FINANCIAL STATEMENTS DECEMBER 31, 2000 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. Vanguard Wellington Fund - This fund invests in dividend-paying large and mid-capitalization stocks of well-established companies, as well as bonds. The fund seeks income and long-term capital appreciation, with an average blend of assets of 65% in stocks and 35% in bonds. At December 31, the investments of the Balanced Funds consisted of the following: 2000 1999 -------------------------------------- ----------------------------------------- Number of Market Number of Market Shares Cost Value Shares Cost Value ------------------------------------------------------------------------------------ Vanguard LifeStrategy Growth Funds * 442,995 $7,992,047 $7,681,046 73,991 $1,277,730 $1,312,238 Vanguard Wellington Fund 55,612 1,576,751 1,568,809 14,972 463,585 418,603 ------- ---------- ---------- ------ ---------- ---------- Total Balanced Fund 498,607 $9,568,798 $9,249,855 88,963 $1,741,315 $1,730,841 ======= ========== ========== ====== ========== ========== * At December 31, investment represents 5% of more of the fair value of the Plan's net assets. (c) The Equity Funds: The Equity Funds consist of mutual funds primarily in the Vanguard Group of Equity Funds. The fund includes the Vanguard Windsor II Fund, the Vanguard PRIMECAP Fund, the Vanguard International Growth Fund, the Vanguard Small-Cap Index Fund and the Vanguard 500 Index Fund. Equity Fund participants may also invest in the Fidelity Magellan Fund, which is a broadly diversified mutual fund investing in a wide range of worldwide stocks and other types of investments. The BlackRock Small Cap Growth Portfolio is also included in the Equity Fund. Both the Vanguard funds and the BlackRock fund seek long-term capital appreciation. All of the mutual funds mentioned above use various investment techniques, including foreign exchange and derivatives transactions, though generally these funds have significant limitations as to the use of such techniques. Shares in each fund are purchased at the net asset value of the respective funds and no direct commissions, fees or other charges are assessed against the accounts in these funds. F-8

(d) The Common Stock Fund: At December 31, 2000, the assets of the Common Stock Fund were invested in AMETEK, Inc. common stock. At December 31, 2000, the investment consisted of 53,991 shares having a cost of $370,106 and a market value of $459,464. Shares of AMETEK, Inc. common stock may be purchased by the Trustee on the open market, directly from AMETEK, or from other stockholders. Brokerage commissions paid are charged against the accounts invested in this Fund. 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 1,300 participants in the Plan at December 31, 2000. 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 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, 2000 ranged between 7.75% and 11.5%. F-9

12 THE AMETEK 401(K) PLAN FOR ACQUIRED BUSINESSES NOTES TO FINANCIAL STATEMENTS DECEMBER 31, 2000 6. FEDERAL INCOME TAX STATUS The Plan will apply for a determination letter from the Internal Revenue Service stating that the Plan is qualified under Section 401 of the Internal Revenue Code, and would, therefore, be exempt from federal income tax. However, the Plan Administrator believes that the Plan is qualified and, therefore, the related trust is exempt from Federal income tax. Under the Plan, contributions will not be taxed to the employee until a distribution from the Plan is made. 7. EXPENSES The expenses of administering the Plan are payable from the trust funds, unless the Company elects to pay such expenses. For all Plan periods presented, the Company elected to pay such expenses directly. F-11
