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

Sealed Air Corporation (the “Company”) sponsors the 2005 Contingent Stock Plan of Sealed Air Corporation, as amended (the “Plan”), under which the Company can grant awards of restricted stock, restricted stock units, performance share units, or cash to eligible employees and consultants of the Company.

As previously disclosed in the proxy statement for our 2013 Annual Meeting of Stockholders, on February 14, 2013, the Organization and Compensation Committee of the Board of Directors (the “Committee”) of the Company amended the Plan, subject to stockholder approval, to increase the maximum number of shares of Company common stock that may be issued to an employee with respect to performance share units during any calendar. This amendment to the Plan was approved by a majority of the Company’s stockholders on May 16, 2013.

On July 11, 2013, the Committee further amended the Plan to eliminate certain minimum vesting requirements in order to give the Committee greater flexibility in granting awards under the Plan. The Committee has approved an amendment and restatement of the Plan to reflect these amendments to the Plan.

The result of these changes to the Plan are to (i) increase the maximum number of shares of Company common stock that may be issued to an employee with respect to performance share units during any calendar year from two tenths of one percent (0.2%) to one-half of one percent (0.5%) of the issued and outstanding shares of the Corporation’s common stock on January 1 of such calendar year, and (ii) eliminate certain minimum vesting requirements regarding awards that vest solely based on the passage of time, in order to give the Committee greater flexibility in granting awards under the Plan.

A description of the terms and conditions of the Plan, prior to this amendment and restatement, is set forth in the Company’s Proxy Statement for the 2013 Annual Meeting of Stockholders of the Company as filed with the Securities and Exchange Commission on April 5, 2013, under the heading “Approval of the Amended 2005 Contingent Stock Plan of Sealed Air Corporation (Proposal 12)”, which such description is incorporated herein by reference. The summary of the terms and conditions of the Plan is not a complete discussion of the document. Accordingly, the foregoing is qualified in its entirety by reference to the full text of the Plan included as Exhibit 10.1 to this Current Report on Form 8-K, which is incorporated herein by reference.
