Dear Michael Baker Corporation Registered Holder:
Bowne & Co. recently distributed to you a proxy card on behalf of the Michael Baker Corporation in order to cast your votes for the upcoming Annual Meeting of Stockholders for Michael Baker Corporation. Due to a printing error on the part of Bowne & Co., this card contained erroneous information, specifically that the 2009 agenda and election proposals were printed on the proxy cards instead of the 2010 information.
In light of this error, we hereby provide you with a corrected voting instruction card – we ask that you cast your votes using the instructions found herein, either by Internet, telephone or by mailing your physical card in the enclosed return envelope. In particular, if you have already voted using the erroneous physical card previously delivered to you, we ask that you submit a new vote in accordance with the immediately preceding sentence.
We apologize for any inconvenience this may have caused.
Sincerely,
Bowne & Co., Inc.
