The Election Deadline is based on the closing of the Merger, which remains subject to various conditions, including, among other things, receipt of the requisite approval of shareholders of Sirius, receipt of requisite approval of shareholders of Third Point Re and the receipt of regulatory approvals as provided for in the Merger Agreement. There can be no assurance as to the timing of the closing of the Merger or as to whether the conditions to the completion of the Merger will be satisfied or waived or that the transaction will be completed. Third Point Re and Sirius will publicly announce the Election Deadline and any extensions of the Election Deadline in a press release, on their websites and in a filing with the SEC. Holders of Sirius shares who hold such shares in certificated form must also include with their completed Election Form the certificate(s) representing all their Sirius shares to which the Election Form relates. Holders of Sirius shares who hold such shares in electronic, book-entry form do not need to include any certificate(s) and simply need to return the completed Election Form. Holders of Sirius shares who do not properly and timely make an election as provided in the preceding sentences or who properly and timely revoke a prior election will be considered a Non-Electing Holder (see Instruction A.7 below). You understand and acknowledge that you will not receive the merger consideration unless and until the Merger is complete and the Exchange Agent has received from you all necessary documentation. 2. Certificates and Shares held by the Exchange Agent. The Election Form will indicate the number of shares you hold either in certificated form or in electronic, book-entry form. 3. Election Options. On page 3 of the Election Form, under “Election Options,” indicate whether you would like to receive in exchange for your Sirius shares (i) Cash Consideration, (ii) Share & CVR Consideration, (iii) Mixed Consideration, (iv) a combination of the forgoing, or (v) “No Election.” Mark only one box. 4.

Smith” on another) and by persons who may be considered to own each other’s shares by reason of the ownership attribution rules contained in Section 318(a) of the Internal Revenue Code of 1986, as amended.
