<P align="center" style="font-size: 10pt">Report of Independent Registered Public Accounting Firm



<P align="left" style="font-size: 10pt">Plan Administrative Committee



<DIV align="left" style="font-size: 10pt">AMETEK 401(K) Plan for Acquired Businesses</DIV>



<P align="left" style="margin-left: 0%; text-indent: 0%; margin-right: 0%; font-size: 10pt">We have audited the accompanying statements of assets available for benefits of the AMETEK
401(K) Plan for Acquired Businesses as of December&nbsp;31, 2004 and 2003, and the related
statements of changes in assets available for benefits for the years then ended. These financial
statements are the responsibility of the Plan&#146;s management. Our responsibility is to express an
opinion on these financial statements based on our audits.


<P align="left" style="margin-left: 0%; text-indent: 0%; margin-right: 0%; font-size: 10pt">We conducted our audits in accordance with the standards of the Public Company Accounting Oversight
Board (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. We
were not engaged to perform an audit of the Plan&#146;s internal control over financial reporting. Our
audits included consideration of internal control over financial reporting as a basis for designing
audit procedures that are appropriate in the circumstances, but not for the purpose of expressing
an opinion on the effectiveness of the Plan&#146;s internal control over financial reporting.
Accordingly, we express no such opinion. An audit also includes examining, on a test basis,
evidence supporting the amounts and disclosures in the financial statements, assessing the
accounting principles used and significant estimates made by management, and evaluating the overall
financial statement presentation. We believe that our audits provide a reasonable basis for our
opinion.


<P align="left" style="margin-left: 0%; text-indent: 0%; margin-right: 0%; font-size: 10pt">In our opinion, the financial statements referred to above present fairly, in all material
respects, the assets available for benefits of the Plan at December&nbsp;31, 2004 and 2003, and the
changes in its assets available for benefits for the years then ended, in conformity with U.S.
generally accepted accounting principles.


<P align="left" style="margin-left: 0%; text-indent: 0%; margin-right: 0%; font-size: 10pt">Our audits were performed for the purpose of forming an opinion on the financial statements taken
as a whole. The accompanying supplemental schedule of assets (held at end of year) as of December
31, 2004, is presented for purposes of additional analysis and is not a required part of the
financial statements but is supplementary information required by the Department of Labor&#146;s Rules
and Regulations for Reporting and Disclosure under the Employee Retirement Income Security Act of
1974. This supplemental schedule is the responsibility of the Plan&#146;s management. The supplemental
schedule has been subjected to the auditing procedures applied in our audits of the financial
statements and, in our opinion, is fairly stated in all material respects in relation to the
financial statements taken as a whole.

<P align="center" style="font-size: 10pt">AMETEK 401(K) Plan for Acquired Businesses


<DIV align="center" style="font-size: 10pt">Notes to Financial Statements</DIV>


<DIV align="center" style="font-size: 10pt">December&nbsp;31, 2004</DIV>



<P align="left" style="margin-left: 0%; text-indent: 0%; margin-right: 0%; font-size: 10pt"><B>1. Description of Plan</B>


<P align="left" style="margin-left: 0%; text-indent: 0%; margin-right: 0%; font-size: 10pt"><B>General</B>


<P align="left" style="margin-left: 0%; text-indent: 0%; margin-right: 0%; font-size: 10pt">The following brief description of the AMETEK 401(K) Plan for Acquired Businesses (&#147;the Plan&#148;)
provides only summarized information. Participants should refer to the Plan document for a more
complete description of the Plan&#146;s provisions.


<P align="left" style="margin-left: 0%; text-indent: 0%; margin-right: 0%; font-size: 10pt">The Plan is a tax-deferred 401(k) defined contribution savings plan. The Plan provides
eligible employees of businesses acquired by AMETEK, Inc. (&#147;AMETEK&#148;, or &#147;the Company&#148;), 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).


<P align="left" style="margin-left: 0%; text-indent: 0%; margin-right: 0%; font-size: 10pt"><B>Contributions</B>


<P align="left" style="margin-left: 0%; text-indent: 0%; margin-right: 0%; font-size: 10pt">Each year, participants have an opportunity to invest up to 50% 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. Beginning January&nbsp;1, 2004,
certain groups of participants will have an opportunity to invest up to 75% of their compensation,
as defined by the Plan. Participants may also contribute amounts representing rollovers from other
qualified plans. Also in connection with business acquisitions by AMETEK, account balances from
certain other plans may be transferred into the Plan, or into a separate 401(k)
retirement and savings plan sponsored by AMETEK. 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&#146; compensation as determined by the Board of Directors for each business.
Matching Company contributions are credited to participants&#146; accounts at the same time their
contributed compensation is invested. However, the Company may make its matching contribution
payment to the Plan at anytime prior to the due date prescribed by law for filing the Company&#146;s
federal income tax return for that Plan year.


<P align="left" style="margin-left: 0%; text-indent: 0%; margin-right: 0%; font-size: 10pt"><B>Participant Accounts</B>


<P align="left" style="margin-left: 0%; text-indent: 0%; margin-right: 0%; font-size: 10pt">Each participant&#146;s account is credited with the participant&#146;s contributions and allocations of (a)
the Company&#146;s contributions and (b)&nbsp;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&#146;s account.


<P align="left" style="margin-left: 0%; text-indent: 0%; margin-right: 0%; font-size: 10pt"><B>Vesting</B>


<P align="left" style="margin-left: 0%; text-indent: 0%; margin-right: 0%; font-size: 10pt">Participants are fully vested at all times in both their contributions to the Plan and in Company
contributions.

<P align="left" style="margin-left: 0%; text-indent: 0%; margin-right: 0%; font-size: 10pt"><B>Participant Loans</B>


<P align="left" style="margin-left: 0%; text-indent: 0%; margin-right: 0%; font-size: 10pt">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 loans outstanding at any time,
the sum of which may not exceed the maximum allowable. Repayment terms of the loans are generally
limited to no longer than 60&nbsp;months from inception or for a reasonable period of time in excess of
60&nbsp;months for the purchase of a principal residence, as fixed by the Plan&#146;s Administrative
Committee. The loans are secured by the balance in the participant&#146;s account, and bear interest at
rates established by the Plan&#146;s administrative committee, which approximate rates charged by
commercial lending institutions for comparable loans. Interest rates on loans outstanding at
December&nbsp;31, 2004 and 2003 ranged between 5% and 11.5%. Principal and interest is paid ratably
through payroll deductions. Participant loans outstanding at December&nbsp;31, 2004 and 2003,
respectively, totaled $1,256,749 and $1,282,021 are included in investments in the accompanying
Statements of Assets Available for Benefits.


<P align="left" style="margin-left: 0%; text-indent: 0%; margin-right: 0%; font-size: 10pt"><B>Payment of Benefits</B>


<P align="left" style="margin-left: 0%; text-indent: 0%; margin-right: 0%; font-size: 10pt">On termination of service, death, disability or retirement, a participant may receive a lump-sum
amount equal to his or her vested account or elect to receive payment in installments up to a 15
year period, subject to certain restrictions based on life expectancy. 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<FONT style="font-size: 70%"><SUP>1</SUP></FONT>/<FONT style="font-size: 60%">2</FONT> 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.


<P align="left" style="margin-left: 0%; text-indent: 0%; margin-right: 0%; font-size: 10pt"><B>Plan Termination</B>


<P align="left" style="margin-left: 0%; text-indent: 0%; margin-right: 0%; font-size: 10pt">The Plan is subject to the provisions of the Employee Retirement Income Security Act of 1974
(&#147;ERISA&#148;).


<P align="left" style="margin-left: 0%; text-indent: 0%; margin-right: 0%; font-size: 10pt">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.

<P align="left" style="margin-left: 0%; text-indent: 0%; margin-right: 0%; font-size: 10pt"><B>Basis of financial statements and presentation format</B>


<P align="left" style="margin-left: 0%; text-indent: 0%; margin-right: 0%; font-size: 10pt">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)&nbsp;99-3, &#147;Accounting for and Reporting of Certain Defined Contribution Benefit Plan
Investments and Other Disclosure Matters.&#148;


<P align="left" style="margin-left: 0%; text-indent: 0%; margin-right: 0%; font-size: 10pt"><B>Use of estimates</B>


<P align="left" style="margin-left: 0%; text-indent: 0%; margin-right: 0%; font-size: 10pt">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.


<P align="left" style="margin-left: 0%; text-indent: 0%; margin-right: 0%; font-size: 10pt"><B>Risks and uncertainties</B>


<P align="left" style="margin-left: 0%; text-indent: 0%; margin-right: 0%; font-size: 10pt">The Plan invests in various investment securities. Investment securities are exposed to
various risks such as interest rate, market fluctuation 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&#146; account balances and the amounts reported in the statements of
assets available for benefits.


<P align="left" style="margin-left: 0%; text-indent: 0%; margin-right: 0%; font-size: 10pt"><B>Investment valuation and income recognition</B>


<P align="left" style="margin-left: 0%; text-indent: 0%; margin-right: 0%; font-size: 10pt">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 book value, which approximates fair value.

24, 2002, stating that the Plan is qualified under Section 401(a) of the Internal Revenue Code (the
&#147;Code&#148;) and, therefore, the related trust is exempt from taxation. Subsequent to issuance of the
above 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.
