We have received the affirmative vote of approximately 77 percent of the combined voting power of the Sealed Air stock voting FOR repeal of the supermajority provisions in the Company's Charter (as discussed in our proxy statement). However, 80 percent of the outstanding voting power is required for passage so MORE TOTAL VOTES ARE STILL NEEDED. Over 98 percent of the voting by your fellow Stockholders who have already sent in their proxies has been in favor of repeal of the supermajority provisions, but because shares representing over 20 percent of the voting power have not yet been voted on these issues, we have not reached our goal. We urge you to vote now. Don't let the lack of participation influence the Company's future -- cast your ballot! WHY YOU SHOULD VOTE! Voting FOR repeal of these provisions gives Stockholders greater ability to take action. If you were a Stockholder of Record on March 24, 1999 then YOU ARE ENTITLED TO VOTE, even if you no longer own the shares. In fact, absent special circumstances you would be the only one who could vote those shares. We encourage you to vote as it is a boost for Stockholders' rights. Regardless of the number of shares you hold, you may make the difference in this very close vote. If you are the recipient of this mailing your vote has not yet been tallied per our most recent review, so we encourage you to SEND IN YOUR PROXY TODAY, or vote by telephone or via the Internet. For your convenience, you can also telefax your signed proxy to our corporate headquarters at 201- 703-4113. TAKE ACTION! We encourage you to vote FOR items 3, 4 and 5 on your proxy card or voting instruction form. Recapture your rights as a Stockholder to influence the Company's future! Voting should be completed as soon as possible. The Annual Meeting reconvenes promptly at 10:00 a.m. on July 16, 1999. On behalf of your board of directors, we thank you for your continued support. Sincerely, /s/ T.J. Dermot Dunphy T.J. Dermot Dunphy Chairman of the Board and Chief Executive Officer PLEASE VOTE YOUR PROXY TODAY YOUR VOTE IS IMPORTANT!
