This letter sets forth the terms of your resignation as an executive officer of Nordson Corporation (Nordson) and the terms of a paid leave of absence through January 30, 2015, conditioned upon you signing: (i) this letter agreement (“Agreement”); (ii) the attached Primary Release of Claims (Exhibit 1) within twenty-one (21) days of the date of this letter; and (iii) the attached Secondary Release of Claims (Exhibit 2) during the period from January 30, 2015 through February 21, 2015, or within twenty-one (21) days following your voluntary termination of employment prior to expiration of the leave of absence period. All payments and benefits are also subject to your not revoking any of the Release of Claims during the applicable revocation periods.

1. Cessation of Status as an Officer. Effective June 6, 2014, your status as an executive officer of Nordson, and of any subsidiaries and other affiliates of Nordson of which you are an officer, and your status as a director of The Nordson Corporation Foundation will cease. Accordingly, you will not hold yourself out as being an officer or director, or as having any authority to bind, Nordson, any such subsidiary or affiliate, or The Nordson Corporation Foundation. You agree to execute any documents necessary to reflect the change in status.

Even though you will no longer be an officer of Nordson or of any subsidiary or other affiliate of Nordson, certain restrictions will apply to any purchase or sale of Nordson Common Shares by you. By signing this Agreement, you acknowledge that you have received the summary of those restrictions that is attached to this Agreement as Exhibit 3 hereto and agree that you will comply with those restrictions.

2. Paid Leave of Absence and Transitional Support. You will be placed on a paid leave of absence commencing June 6, 2014 through January 30, 2015 at which time you will be eligible to elect to retire from Nordson Corporation. During this paid leave of absence you agree to provide support for the transition of your managerial duties to other Nordson employees. The paid leave of absence expires the earlier of (i) the expiration of the leave period or (ii) the date you choose to voluntarily terminate your employment with Nordson.

3. Compensation During the Leave of Absence. As part of the consideration for you to execute the Primary Release of Claims (Exhibit 1), Nordson will continue to pay you your FY 2014 base salary on a biweekly basis through the leave of absence period.

4. FY 2014 Cash Incentive Award. As part of the consideration for you to execute the Primary Release of Claims (Exhibit 1), you will receive payment for the FY 2014 Cash Incentive Award on the settlement date of the Award, based on a full year of participation. You will not receive a FY 2015 Incentive Cash Award.

5. Performance Share Awards. As part of the consideration for you to execute the Primary Release of Claims (Exhibit 1), the FY 2012-2014, FY 2013-2015 and FY 2014-2016 Performance Share Awards will be paid on their respective settlement date as follows:

Should you voluntarily terminate your employment prior to the expiration of the leave of absence period, the prorata payouts for the FY 2013-2015 and FY 2014-2016 Performance Share Awards will be adjusted accordingly.

6. Stock Options and Restricted Stock. Unvested stock options and unvested restricted stock granted previously to you under the Amended and Restated Nordson Corporation 2008 Long-Term Performance Plan and Nordson Corporation 2012 Stock Incentive and Award Plan (collectively, the “Plans”) will vest according to the terms of grant for the respective grants and terms of the Plans. No additional stock options or restricted stock will be granted to you.

As part of the consideration for you to execute the Primary Release of Claims (Exhibit 1), should you voluntarily terminate your employment with Nordson prior to the expiration of the leave of absence, stock options and restricted stock then remaining unvested will vest as if you were age 55 on the date your employment with Nordson terminates. Further in such event, your ability to exercise vested stock options will be accordance with terms of grant and rules of the Plans governing the exercise of stock options for Nordson employees who elect to retire at age 55 (early retirement).

7. Health Care Coverage; Pension Plan; 401(k) Plan Through the paid leave of absence period you will continue to participate in the Nordson health care program; Nordson Salaried Employees’ Pension Plan and Nordson Employees Savings Trust Plan (401(k)),

and other welfare benefit plans extended to other full time employees, such as long term disability and life insurance coverage. For the period of the leave of absence, you will be reimbursed for tax planning assistance up to a $5,000 maximum.

8. Payment at the Conclusion of the Leave of Absence. As part of the consideration for you to execute the Secondary Release of Claims (Exhibit 2), you will receive a lump sum payment equal to 4 months of FY 2014 base pay - One Hundred Ten Thousand Dollars ($110,000) - following the expiration of the paid leave of absence period. This payment will be made within (14) fourteen days after you have executed the Secondary Release of Claims (Exhibit 2) and the Release becomes non-revocable.

Should you voluntarily terminate your employment with Nordson prior to the expiration of the leave of absence, and provided you abide by the restrictive covenants outlined below in Section 15 and sign the Secondary Release of Claims (Exhibit 2), the payment of this severance benefit will be accelerated. However, you will not receive the Cobra payment outlined in Section 12 below.

9. Retiree Benefits, Including Medical Insurance Coverage and Life Insurance. If you elect to retire under the Nordson Corporation Salaried Employees Pension Plan on or after the date you become eligible for early retirement, Nordson will provide you and your family with all benefits extended to retirees of the Company, including but not limited to medical insurance coverage and retiree life insurance, as and to the extent provided by Nordson’s programs for retirees, as those programs may be amended from time to time.

10. Excess Pension Benefit and Deferred Compensation. Distribution of your account balance in the 2005 Excess Defined Benefit Pension Plan and 2005 Officers’ Deferred Compensation Plan also will be determined by the current distribution election on file and terms of those plans, respectfully, subject to the payout deferral rules under Section 409A of the Internal Revenue Code.

11. Outplacement Services. You will receive outplacement services provided by Right Management Consultants or other firm retained by Nordson to provide such services.

12. Health Care Continuation. Loss of health care coverage is considered a “qualifying event” under federal law governing health care coverage (“Cobra”). Under Cobra, you are permitted to continue health care coverage at your expense for a period of up to 18 months following a loss of coverage.

Should you elect not to commence a pension benefit February 1, 2015 you may continue health care coverage for 18-months provided you make premium payments to Nordson’s Cobra administrator (currently United Health Care). As further consideration for executing the Secondary Release of Claims (Exhibit 2), Nordson will reimburse you for (4) four months of Cobra continuation coverage should you timely elect such coverage. Payment of premiums for the balance of the Cobra continuation period will be your responsibility. Specifics of the health care continuation program will be mailed to you separately.

Any health care continuation will cease if during the 18-month period you become covered under a health care program which offers coverage similar to that available to Nordson employees.

13. Nordson Equipment and Property. As soon as practicable, you will return to Nordson any equipment and property that belongs to Nordson, and all materials that contain any Nordson confidential or proprietary information (including any electronic storage devices), that you may have in your possession.
