Item 5.02: Departure of Directors or Certain Officers; Election of Directors;
Appointment of Certain Officers; Compensatory Arrangements of Certain Officers

The Board of Directors of Cognex Corporation (the "Company") adopted a new stock
option plan, the 2007 Stock Option and Incentive Plan (the "2007 Plan"), in
February 2007, which remains subject to the approval of the Company's
shareholders at the annual meeting of shareholders to be held on April 18, 2007
(the "Annual Meeting"). The maximum number of shares of the Company's common
stock that could be issued under the 2007 Plan is 2,300,000 shares. The Company
has determined that, if the 2007 Plan is approved by the Company's shareholders
at the Annual Meeting, the Company will reduce the number of shares authorized
for issuance under its existing stock option plans by an aggregate of 4,000,000
shares. The reduction would be made from the shares remaining for future
issuance under the Company's 1998 Non-Employee Director Stock Option Plan, the
1998 Stock Incentive Plan, and/or the 2001 General Stock Option Plan. As
reported in the Company's proxy statement for the Company's Annual Meeting,
there were a total of 10,883,676 shares remaining available for future issuance
under these three equity compensation plans.
