As disclosed in the Current Report on Form 8-K filed by Cognex Corporation (the
"Company") with the Securities and Exchange Commission on July 26, 2007, the
Audit Committee of the Company's Board of Directors is conducting a voluntary
internal review, with the assistance of independent outside counsel, of certain
transactions originating at the Company's Japanese subsidiary. The Company will
not be in a position to file its Quarterly Report on Form 10-Q for the three
months ended July 1, 2007 until after completion of the review. The Audit
Committee is working to resolve this matter in a timely manner, including within
the extension provided by Rule 12b-25 of the Securities Exchange Act of 1934.
