Cautionary Note Regarding Forward-Looking Statements Cautionary Note Regarding Forward-Looking Statements: This presentation may include forward-looking statements, both with respect to us and our industry, that reflect our current views with respect to future events and financial performance. Statements that include the words “expect,” “intend,” “plan,” “believe,” “project,” “anticipate,” “will,” “may” and similar statements of a future or forward-looking nature identify forward-looking statements. All forward-looking statements address matters that involve risks and uncertainties, many of which are beyond our control. Accordingly, there are or will be important factors that could cause actual results to differ materially from those indicated in such statements and, therefore, you should not place undue reliance on any such statements. We believe that these factors include, but are not limited to, the following: 1) uncertainty as to whether Validus will be able to enter into and to consummate the proposed acquisition on the terms set forth in the improved Validus amalgamation offer; 2) uncertainty as to the actual premium that will be realized by IPC shareholders in connection with the proposed acquisition; 3) uncertainty as to the long-term value of Validus common shares; 4) unpredictability and severity of catastrophic events; 5) rating agency actions; 6) adequacy of Validus’ or IPC’s risk management and loss limitation methods; 7) cyclicality of demand and pricing in the insurance and reinsurance markets; 8) Validus’ limited operating history; 9) Validus’ ability to implement its business strategy during “soft” as well as “hard” markets; 10) adequacy of Validus’ or IPC’s loss reserves; 11) continued availability of capital and financing; 12) retention of key personnel; 13) competition; 14) potential loss of business from one or more major insurance or reinsurance brokers; 15) Validus’ or IPC’s ability to implement, successfully and on a timely basis, complex infrastructure, distribution capabilities, systems, procedures and internal controls, and to develop accurate actuarial data to support the business and regulatory and reporting requirements; 16) general economic and market conditions (including inflation, volatility in the credit and capital markets, interest rates and foreign currency exchange rates); 17) the integration of Talbot or other businesses we may acquire or new business ventures we may start; 18) the effect on Validus’ or IPC’s investment portfolios of changing financial market conditions including inflation, interest rates, liquidity and other factors; 19) acts of terrorism or outbreak of war; 20) availability of reinsurance and retrocessional coverage; 21) failure to realize the anticipated benefits of the proposed acquisition, including as a result of failure or delay in integrating the businesses of Validus and IPC; and 22) the outcome of litigation arising from the Validus Offer for IPC, as well as management’s response to any of the aforementioned factors. The foregoing review of important factors should not be construed as exhaustive and should be read in conjunction with the other cautionary statements that are included herein and elsewhere, including the risk factors included in our most recent reports on Form 10-K and Form 10-Q and the risk factors included in IPC’s most recent reports on Form 10-K and Form 10-Q and other documents of Validus and IPC on file with the Securities and Exchange Commission (“SEC”). Any forward-looking statements made in this presentation are qualified by these cautionary statements, and there can be no assurance that the actual results or developments anticipated by Validus will be realized or, even if substantially realized, that they will have the expected consequences to, or effects on, us or our business or operations. Except as required by law, we undertake no obligation to update publicly or revise any forward-looking statement, whether as a result of new information, future developments or otherwise. No rating agency (A.M. Best, Moody’s, or Standard & Poor’s) has specifically approved or disapproved or otherwise taken definitive action on the potential transaction. 1

Proposed Acquisition Additional Information about the Proposed Acquisition and Where to Find It: This presentation relates to the Exchange Offer by Validus to exchange each issued and outstanding common share of IPC for 1.1234 voting common shares of Validus and $3.75 in cash.
