Item 2.05  Costs Associated with Exit or Disposal Activities

Due to the global business environment, on April 21, 2009, Cognex Corporation
(the "Company") initiated steps to cut expenses by an additional $15 million on
an annualized basis to endeavor to more closely align costs with the decreased
level of demand for the Company's products. These actions, which augment those
taken by the Company in November of 2008, include cuts in certain executive
salaries, the elimination of approximately 85 employees and contractors, the
cancellation of most current open positions, additional mandatory shut-down
days, a reduction in leased office space, a lower company contribution to the
401(k) plan, and decreases in discretionary spending. As a result of these
actions, the Company expects to record a pre-tax charge of approximately $4
million in the second quarter of 2009, of which approximately $3 million will
relate to employee-related expenses and approximately $1 million will relate to
the reduction in leased office space. The Company expects approximately $4
million of the charge to result in future cash expenditures. The Company expects
to complete these actions in the second quarter of 2009.
