Item 1.01 Entry into a Material Definitive Agreement.

On November 27, 2013, Sealed Air Corporation (the “Company”) amended (the “Amendment”) its senior secured credit facility (as so amended, the “Amended Credit Agreement”) with the lenders party thereto, Citibank, N.A., as agent, and the other parties thereto. The amendment refinanced the term loan B facilities with a $524.5 million term loan B dollar tranche and a €127.5 million term loan B euro tranche. In connection therewith, among other things, (i) the interest margin on each tranche was decreased by 0.75%, (ii) the minimum Eurocurrency rate under the term loan B facilities was reduced from 1.00% to 0.75%, and (iii) the Amendment provided for a six-month “soft-call” prepayment protection on the applicable term loan B tranches. The foregoing description of the Amended Credit Agreement does not purport to be complete and is qualified in its entirety by reference to the full text of the Amendment, which is filed as Exhibit 10.1 hereto and incorporated by reference herein.
