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

At a special meeting in lieu of the annual meeting of shareholders of Cognex
Corporation (the "Company") held on April 18, 2007, the shareholders of the
Company approved the Cognex Corporation 2007 Stock Option and Incentive Plan
(the "2007 Plan"). The 2007 Plan will take effect when the Company's 1998 Stock
Incentive Plan (the "1998 Plan") expires in February of 2008. The 2007 Plan
permits awards of stock options (both incentive and non-qualified options),
stock appreciation rights and restricted stock. The maximum number of shares to
be issued under the 2007 Plan is 2,300,000 shares of the Company's common stock.
A summary of the material terms and conditions of the 2007 Plan is set forth in
the Company's definitive Proxy Statement filed with the Securities and Exchange
Commission on March 14, 2007 (the "Proxy Statement"), under the caption
"Proposal 2: Approval of 2007 Stock Option and Incentive Plan." Such description
is incorporated herein by reference and is qualified in its entirety by
reference to the full text of the 2007 Plan, which is filed as Exhibit 10.1 to
this Current Report on Form 8-K.

The Company has determined that, given approval by the Company's shareholders of
the 2007 Plan, 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 will be made from the shares remaining for future issuance
under the Company's 1998 Non-Employee Director Stock Option Plan, the 1998 Plan,
and/or the 2001 General Stock Option Plan. As reported in the Proxy Statement,
as of December 31, 2006, there were a total of 10,883,676 shares remaining
available for future issuance under these three equity compensation plans.
