Explanation of Responses:

* If the form is filed by more than one reporting person, see Instruction 4(b)(v).
** Intentional misstatements or omissions of facts constitute Federal Criminal Violations. See 18 U.S.C. 1001 and 15 U.S.C. 78ff(a).
(1) Disposed of in connection with the Agreement and Plan of Merger ("Merger Agreement") between the Issuer, RenaissanceRe Holdings Ltd. ("RenaissanceRe") and Port Holdings Ltd., dated as of November 23, 2014.
(2) Pursuant to the terms of the Merger Agreement, upon closing of the merger, these Common Shares will be cancelled and the holder will receive, per their election, an amount equal to $66.00 in cash per each Common Share, subject to proration.
(3) This consideration amount is subject to adjustment due to possible proration calculations provided for in the Merger Agreement. Specifically, the cash election consideration is subject to proration if the un-prorated aggregate share consideration is less than 7,500,000 RenaissanceRe common shares, and the share election consideration is subject to proration if the un-prorated aggregate share consideration is greater than 7,500,000 RenaissanceRe common shares. This proration calculation has not been finalized as of the date of this Form 4 and thus it is not possible to determine the exact amount of consideration to be received by the reporting person as of the date of this Form 4. Once the exact amount of consideration is determined, the reporting person will file an amendment to this Form 4, if necessary.
(4) These Market Share Units were granted on July 24, 2013. Pursuant to the terms of the Merger Agreement, upon closing of the merger, these Market Share Units will be cancelled and the holder will receive, per their election, an amount equal to $66.00 in cash per each MSU achieved share (as defined in the Merger Agreement), subject to proration. The MSU achieved shares equaled 1.33 times each Market Share Unit, based on the difference between the average closing prices of the Common Shares for the twenty trading days ending on February 27, 2015 and June 30, 2013.
(5) These Market Share Units were granted on July 23, 2012. Pursuant to the terms of the Merger Agreement, upon closing of the merger, these Market Share Units will be cancelled and the holder will receive, per their election, an amount equal to $66.00 in cash per each MSU achieved share (as defined in the Merger Agreement), subject to proration. The MSU achieved shares equaled 1.5 times each Market Share Unit, based on the difference between the average closing prices of the Common Shares for the twenty trading days ending on February 27, 2015 and June 30, 2012.
