<P align="left" style="font-size: 10pt">(a)&nbsp;On March&nbsp;18, 2009, the Audit Committee of the Board of Directors (the &#147;Audit Committee&#148;) of Altra Holdings, Inc., a
Delaware corporation and Altra Industrial Motion, Inc., a Delaware corporation (collectively, the &#147;Companies&#148;)
dismissed Ernst &#038; Young LLP (&#147; E&#038;Y &#148;) as the Companies&#146; independent registered public accounting firm effective as of
March&nbsp;20, 2009, the date of the filing of Altra Industrial Motion, Inc.&#146;s Annual Report on Form 10-K. The actions of
the Audit Committee were ratified by the Board of Directors of the Companies on March&nbsp;18, 2009.


<P align="left" style="font-size: 10pt">The reports of E&#038;Y on the Companies&#146; consolidated financial statements for its fiscal years ended December&nbsp;31, 2008 and
2007 did not contain any adverse opinion or disclaimer of opinion and were not qualified or modified as to uncertainty,
audit scope or accounting principle.


<P align="left" style="font-size: 10pt">During the Companies&#146; fiscal years ended December&nbsp;31, 2008 and 2007 and through March&nbsp;18, 2009, (i)&nbsp;there were no
disagreements with E&#038;Y on any matter of accounting principles or practices, financial statement disclosure or auditing
scope or procedure, which, if not resolved to the satisfaction of E&#038;Y, would have caused E&#038;Y to make reference to the
subject matter of the disagreement in connection with its reports for such years, and (ii)&nbsp;there were no &#147;reportable
events&#148; as defined in Item&nbsp;304(a)(1)(v) of Regulation&nbsp;S-K.


<P align="left" style="font-size: 10pt">The Companies have provided E&#038;Y with a copy of the foregoing disclosure and have requested that E&#038;Y furnish the
Companies with a letter addressed to the Securities and Exchange Commission stating whether or not it disagrees with
the above statements. A copy of the letter from E&#038;Y, dated March&nbsp;20, 2009, is attached as Exhibit&nbsp;16.1 to this Current
Report on <FONT style="white-space: nowrap">Form&nbsp;8-K.</FONT>


<P align="left" style="font-size: 10pt">(b)&nbsp;On March&nbsp;18, 2009, the Audit Committee appointed Deloitte &#038; Touche LLP (&#147;D&#038;T&#148;) as the Companies&#146; new independent
registered public accounting firm. The actions of the Audit Committee were ratified by the Board of Directors of the
Companies on March&nbsp;18, 2009. The appointment of D&#038;T will be presented to the stockholders for ratification at the
Company&#146;s 2009 Annual Meeting of Stockholders. During the Companies&#146; fiscal years ended December&nbsp;31, 2008 and 2007 and

either completed or proposed, or the type of audit opinion that might be rendered on the Companies&#146; consolidated
financial statements, and no written report or oral advice was provided by D&#038;T to the Company that D&#038;T concluded was an
important factor considered by the Company in reaching a decision as to the accounting, auditing, or financial
reporting issue, or (ii)&nbsp;any matter that was the subject of either a disagreement as defined in Item&nbsp;304(a)(1)(iv) of
Regulation&nbsp;S-K or a reportable event as described in Item&nbsp;304(a)(1)(v) of Regulation&nbsp;S-K.

Item 4.01 Change in Registrant's Certifying Accountant.
(a) On March 18, 2009, the Audit Committee of the Board of Directors (the "Audit Committee") of Altra Holdings, Inc., a
Delaware corporation and Altra Industrial Motion, Inc., a Delaware corporation (collectively, the "Companies")
dismissed Ernst & Young LLP (" E&Y ") as the Companies' independent registered public accounting firm effective as of
March 20, 2009, the date of the filing of Altra Industrial Motion, Inc.'s Annual Report on Form 10-K. The actions of
the Audit Committee were ratified by the Board of Directors of the Companies on March 18, 2009.
The reports of E&Y on the Companies' consolidated financial statements for its fiscal years ended December 31, 2008 and
2007 did not contain any adverse opinion or disclaimer of opinion and were not qualified or modified as to uncertainty,
audit scope or accounting principle.
During the Companies' fiscal years ended December 31, 2008 and 2007 and through March 18, 2009, (i) there were no
disagreements with E&Y on any matter of accounting principles or practices, financial statement disclosure or auditing
scope or procedure, which, if not resolved to the satisfaction of E&Y, would have caused E&Y to make reference to the
subject matter of the disagreement in connection with its reports for such years, and (ii) there were no "reportable
events" as defined in Item 304(a)(1)(v) of Regulation S-K.
The Companies have provided E&Y with a copy of the foregoing disclosure and have requested that E&Y furnish the
Companies with a letter addressed to the Securities and Exchange Commission stating whether or not it disagrees with
the above statements. A copy of the letter from E&Y, dated March 20, 2009, is attached as Exhibit 16.1 to this Current

through March 18, 2009, the date of the selection of D&T, neither the Companies, nor any person on their behalf, have
consulted with D&T with respect to either (i) the application of accounting principles to a specified transaction,
either completed or proposed, or the type of audit opinion that might be rendered on the Companies' consolidated
financial statements, and no written report or oral advice was provided by D&T to the Company that D&T concluded was an
important factor considered by the Company in reaching a decision as to the accounting, auditing, or financial
reporting issue, or (ii) any matter that was the subject of either a disagreement as defined in Item 304(a)(1)(iv) of
