<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;AMETEK, Inc. hereby amends the following items of its Annual Report on Form 10-K for the
fiscal year ended December&nbsp;31, 2004 originally filed with Securities and Exchange Commission on
March&nbsp;8, 2005 (the &#147;Original 10-K&#148;) as set forth below and in the pages attached hereto:

<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<B>Signatures</B>

<P align="left" style="font-size: 10pt">Except for the revision to Item&nbsp;9A and other amendments described above, this Amendment No.&nbsp;1 to
the Annual Report on Form
10-K/A does not modify or update other disclosures in, or exhibits to the Original 10-K.



<P align="left" style="font-size: 10pt"><B>Item&nbsp;9A. </B><B><I>Controls and Procedures</I></B>



<P align="left" style="font-size: 10pt"><I>Disclosure Controls and Procedures</I>



<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The Company maintains a system of disclosure controls and procedures that is designed to
provide reasonable assurance that information, which is required to be disclosed, is accumulated
and communicated to management in a timely manner. The Company&#146;s principal executive officer and
principal financial officer evaluated the effectiveness of the system of disclosure controls and
procedures as of December&nbsp;31, 2004. Based on that evaluation, the Company&#146;s principal executive
officer and principal financial officer concluded that the Company&#146;s disclosure controls and
procedures are effective in all material respects as of December&nbsp;31, 2004.


<P align="left" style="font-size: 10pt"><I>Internal Control over Financial Reporting</I>



<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Management&#146;s report on the Company&#146;s internal controls over financial reporting is included
on page 29. The report of the independent registered public accounting firm with respect to
Management&#146;s assessment of the effectiveness of internal control over financial reporting, and
the effectiveness of internal control over financial reporting is included on page 30.


<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Such evaluation did not identify any change in the Company&#146;s internal control over financial
reporting during the quarter ended December&nbsp;31, 2004 that has materially affected, or is a
reasonably likely to materially affect, the Company&#146;s internal control over financial reporting.
