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

Item 5.02(e). On July 9, 2009, the Compensation Committee of the Board of Directors took action to amend the Nordson Corporation Amended and Restated 2005 Supplemental Executive Retirement Plan [Defined Benefit] to change the interest rate assumption employed to calculate the lump sum optional method of payment permitted under the Plan.

The Committee elected to change the interest rate assumption used to calculate the lump sum pension payment from the 30-year Treasury Security Rate published for the month prior to retirement to the average of the 30-year Treasury Security Rate for the 12 months prior to retirement. The purpose of the change is to counter the month-to-month volatility in the value of the lump sum payment that would be paid upon retirement of an executive officer thereby reducing the influence of such volatility on the timing of an executive officer’s retirement decision.
