Press Release

20 October 2011

Omega Insurance Holdings Limited ("Omega" or the "Company")

Update on the Process

On 17 October 2011 the Omega Board (the "Board") announced that it would be consulting shareholders on the terms of the proposals put to Omega by Haverford (Bermuda) Limited ("Haverford"), Canopius Group Limited ("Canopius") and Barbican Insurance Group Limited ("Barbican"). The Board is now able to provide an update following those discussions.

The Canopius proposal requires a commitment to a substantial reinvestment of cash proceeds into the enlarged unquoted Canopius group by certain funds managed by Invesco Perpetual. Invesco Perpetual has confirmed to the Board that the Haverford offer, including Mark Byrne's appointment as Executive Chairman of Omega, has its support in preference to the Barbican and Canopius proposals. In terms of shareholder support and commercial rationale, the Board and its advisers have concluded that the Barbican proposal is not in shareholders' interests. Following the confirmation from Invesco Perpetual, the Board's own deliberations and its discussions with major shareholders, the Board believes that the Haverford offer is the only proposal capable of being concluded at this time.

The Board is aware that amongst the larger shareholders there are different views on the form of the most appropriate transaction, with some shareholders seeking a continued exposure to Omega's business and others seeking a cash exit. In view of Invesco Perpetual's preference for the Haverford offer, no alternative is available to shareholders at present which gives a total cash exit. The Haverford offer gives shareholders an opportunity of receiving some cash in the near term and continuing with all or part of their current shareholding in a listed Omega.

The Board believes that it is in the best interests of Omega for the Haverford offer to be put to all shareholders. The Board will now therefore focus on completing the Haverford offer, enabling the Board and staff to concentrate solely on taking the business forward.

The Board will update shareholders as appropriate.
