SEPARATION AGREEMENT BETWEEN DIVERSEY, INC. AND JAMES LARSON

Exhibit 10.39

SEPARATION AGREEMENT BETWEEN

DIVERSEY, INC. AND JAMES LARSON

The following sets forth the mutual agreement (“Agreement”) between you and Diversey, Inc. (the “Company”), formerly known as JohnsonDiversey, Inc., regarding your separation from the Company:

1. Resignation. You hereby submit and the Company hereby accepts your irrevocable written resignation as an officer and employee of the Company, its subsidiaries and affiliates effective October 18, 2010 (such date of resignation being herein referred to as the “Termination Date”). Your resignation effective on the Termination Date constitutes a “separation from service” (as such phrase is defined under Internal Revenue Code Section 409A and the regulation promulgated thereunder).

2. Severance Pay and Benefits. Subject to the terms of this Agreement, the Company will pay or provide to you following your Termination Date:

a. Salary Continuation. The Company will pay you an amount equal to two times the sum of your current annual rate of Base Salary ($318,270) and your Annual Incentive Plan (“AIP”) bonus opportunity at your 2010 target rate ($159,135) as salary continuation which will be paid over 24 months following the Termination Date. Payments of this salary continuation amount of $954,810 will be paid in equal installments at the times and in the manner consistent with Company payroll practices for executive employees, and each installment payment shall be considered a separate payment and not one of a series of payments for purposes of Section 409A of the Internal Revenue Code. Payments will have all federal, state and local withholding taxes deducted, as applicable.

b. Health Benefits. The medical, dental and vision coverage you elected under the Diversey Choice Benefits Program will cease on your Termination Date. At your option, you may continue your coverage for yourself and your eligible dependents on your Termination Date for a period of 24 months, inclusive of 18 months of COBRA. Please contact the DI Service Center at (866)  ###-###-#### for more detailed information. If you elect any such continued coverage, the Company will subsidize the medical, vision and dental rates for the 24 months of continuation coverage following your Termination Date so that for the same coverage you will pay the same amount of contribution as if you were an active employee; provided, however, that with respect to any such medical, dental and vision benefits provided under a self-insured medical reimbursement plan (within the meaning of Section 105(h) of the Internal Revenue Code), (a “Self-Insured Medical Plan”), for which you have elected coverage, the reimbursement of an eligible medical expense must be made on or before the last day of the calendar year following the calendar year in which the expense was incurred, (B) you must pay to the Company

the cost, on an after-tax basis, for the premium payments (both the employee and employer portion) required for such continued coverage under any Self-Insured Medical Plan, and (C) the Company will pay to you or your eligible dependents on the first day of each month during such period of continuation coverage, an additional severance payment in an amount such that the net amount of such severance pay, after all applicable tax withholding, equals the difference between the full COBRA premium and the premium charged to active employees, which amount shall be applied towards your foregoing payment obligation of the premium for coverage during such month.

c. Choice Benefits. As with the health benefits, the coverage you elected will cease on your Termination Date.

d. 2010 AIP. You will receive, on a prorated basis, a 2010 AIP bonus payment based on the target bonus rate for 2010 of $159,135, with your prorated entitlement to be determined by multiplying such amount by a fraction, the numerator of which is the number of days in 2010 through your Termination Date and the denominator of which is 365. This payment will be made after the end of 2010 at the time the Company pays 2010 awards under the AIP but in no event will payment be made later than March 15, 2011 and will be subject to all federal, state and local withholding taxes, as applicable.

e. Purchased Shares. The 50,000 shares of Diversey Holdings, Inc. common stock (“Common Stock”) that you have purchased under your Employee Stock Subscription Agreement (Purchased Shares) dated as of February 18, 2010 will be repurchased pursuant the provisions of such agreement following your Termination Date.

f. Matched Options. You will become vested on your Termination Date in 20.8% of the options for 150,000 shares of Common Stock granted to you pursuant to your Employee Stock Option Agreement (Matching (non-DSU) and/or Standalone Options) dated as of February 18, 2010 and will be paid in cash within 60 days after your Termination Date an amount equal to the excess of the Fair Market Value (within the meaning of the Diversey Holdings, Inc. Stock Incentive Plan) (“Fair Market Value”) of such vested option shares on your Termination Date over the aggregate option price thereof. Any remaining options under such agreement shall be forfeited on your Termination Date, and you shall be entitled to no further benefits under such agreement. You will forfeit on your Termination Date all options granted to you pursuant to your Employee Stock Option Agreement (2008-2010 DSUs) dated as of January 11, 2010, and Employee Stock Option Agreement (2009-2011 DSUs) dated as of January 11, 2010.

g. 2008-10 DSUs. You will receive a cash payment for the 2008-10 performance cycle under your Deferred Share Unit Agreement dated January 11, 2010 equal to the sum of (i) 100% of your earned 2008-2010 Deferred Share Units (“2008-2010 DSUs”) for the 2008-2009 period based on actual performance and (ii) 83.33% of your unearned DSUs for the 2010 period at target, then multiplied by the Fair Market Value of a share of Common Stock on your Termination Date. Payment of the amount so determined will be paid after the end of the 2008-10 performance cycle at the time DSUs of other participants are settled for such cycle. Such payment will be subject to all

Payment of the amount so determined will be paid after the end of the 2009-11 performance cycle at the time DSUs for other participants are settled for such cycle. Such payment will be subject to all federal, state, and local withholding taxes, as applicable. You shall be entitled to no further benefits with respect to your DSUs under your Deferred Share Unit Agreement for the 2009-11 performance cycle.
