Today, we filed a preliminary proxy statement with the Securities
and Exchange Commission (the SEC). The preliminary proxy statement relates to a special meeting that SeaBright will hold for its stockholders to consider and vote on the proposed acquisition of SeaBright by Enstar Group Limited
(Enstar). The merger agreement between Enstar and SeaBright requires SeaBright to hold this special meeting as promptly as we can, and approval of the merger by SeaBrights stockholders is one of the conditions to completing the
merger. All SeaBright stockholders will be invited to attend the special meeting and vote in person, but the proxy statement and accompanying proxy that we will mail to our stockholders will allow stockholders to vote their shares of SeaBright
common stock without attending the special meeting in person. You can obtain a copy of the preliminary proxy statement by visiting the SECs website at www.sec.gov.
The information contained in the preliminary proxy statement that we filed today is not final and may be changed. In addition, todays preliminary filing does not contain certain information,
including the time, date and place of the special meeting. We will announce the time, date and place of the special meeting once they are determined.
When the proxy statement is finalized, we will file a definitive proxy statement with the SEC and mail it with a proxy to all SeaBright stockholders. If you are a stockholder, you should read the
definitive proxy statement when it becomes available. The proxy statement contains important information about the proposed merger, including instructions on how stockholders can vote, what will happen to SeaBright stock and options if the merger is
consummated, the background and reasons for the merger and a summary of the merger agreement between Enstar and SeaBright.
We are working
towards completing the merger as soon as possible. While the exact date of closing the transaction is uncertain at this time, if our stockholders vote to approve the merger and we obtain the necessary regulatory approvals and satisfy other closing
conditions, we anticipate that the merger will be completed in the fourth quarter of 2012 or the first quarter of 2013.
