The total value of the Severance Payments is Eight Hundred Ten Thousand Dollars and Eighty-Eight Cents ($810,000.88), less applicable deductions and withholdings. Severance Payments will begin no later than sixty (60) days after I have executed this Agreement and have not revoked the same.

b. Benefits Continuation If I elect to continue to participate in the Company’s medical and/or dental plans for team members pursuant to a valid COBRA election, the Company will pay me during the Severance Period the difference between my actual COBRA premium costs and the amount I would have paid had I continued coverage as a team member under the Company’s applicable health plans. The Company’s obligation under 2(b) will (i) not extend beyond the Severance Period; (ii) will cease if I discontinue COBRA benefits; or (iii) be reduced or eliminated to the extent I receive similar coverage and benefits under the plans and programs of a subsequent employer or entity or I become eligible for similar coverage under my spouse’s employer.

c. Outplacement Assistance.

Information on Lee Hecht Harrison will be mailed to me should I execute and not revoke this Agreement.

d. Annual Incentive Plan Award I understand that I shall be eligible for an Annual Incentive Award, prorated for my service period and pursuant to the terms of the applicable Annual Incentive Plan for Fiscal Year 2018 (the “AIP”). Such award shall be determined in accordance with the terms of the AIP, and I acknowledge that an award is not guaranteed under the AIP. The amount to be paid to me, if any, shall be paid in the first quarter of 2018, at such time as the awards are paid to other eligible employees generally.

e. Other Benefit Plans Except as set forth in 2 (d) above, I understand that for benefit plans governed by the Employee Retirement Income Security Act of 1974 (ERISA) and equity or similar awards granted or assumed by the Company, my eligibility for benefits will be determined in accordance with the terms of the applicable plan or other governing documents. Nothing in this Agreement shall impair, diminish or interfere with any rights, privileges or benefits I have with respect to ERISA plans, equity award agreements or similar governing documents. Except as described above, I hereby withdraw my participation in any and all bonus or incentive plan(s) or program(s) and understand that I am not now nor will in the future be entitled to any payments under those plans.
