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

On May 14, 2015, the Organization and Compensation Committee of the Board of Directors of Sealed Air Corporation (the “Company”) approved the offer letter between Dr. Ilham Kadri, President, Diversey Care, and the Company regarding her relocation from the Netherlands to the Company’s new headquarters in Charlotte, North Carolina (the “Relocation Letter”). Upon Dr. Kadri’s relocation, the current employment agreement between Dr. Kadri and Diversey Europe Operations BV (a subsidiary of the Company) dated February 25, 2013 will terminate.

The Relocation Letter establishes Dr. Kadri’s salary in U.S. dollars at $477,000 and leaves her Annual and Long Term Incentive targets as a percentage of salary unchanged at 65% and 160%, respectively. In order to address the timing of the relocation, the loss of certain customary benefits provided under her terminating employment agreement and certain differences in anticipated taxes related to outstanding performance share unit (PSU) awards, the Relocation Letter provides Dr. Kadri with (i) one academic year of school tuition for her child, (ii) certain one-time payments totaling $121,650, a portion of which is net of tax, and (iii) certain future potential tax equalization payments related to her outstanding PSUs. The Relocation Letter also provides for an amendment to her outstanding PSUs to treat any termination of employment without “cause” before March 31, 2018 the same as “retirement” (i.e., resulting in pro rata vesting subject to actual performance results). All other Company benefits under the Relocation Letter, including relocation benefits, generally follow standard Company programs.

The foregoing summary of the Relocation Letter is qualified in its entirety by reference to the full text of the Relocation Letter included as Exhibit 10.1 to this Current Report on Form 8-K, which is incorporated herein by reference.
