THIRD QUARTER 2011 Investor Presentation

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. 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) unpredictability and severity of catastrophic events; 2) rating agency actions; 3) adequacy of Validus’ risk management and loss limitation methods; 4) cyclicality of demand and pricing in the insurance and reinsurance markets; 5) statutory or regulatory developments including tax policy, reinsurance and other regulatory matters; 6) Validus’ ability to implement its business strategy during “soft” as well as “hard” markets; 7) adequacy of Validus’ loss reserves; 8) continued availability of capital and financing; 9) retention of key personnel; 10) competition; 11) potential loss of business from one or more major insurance or reinsurance brokers; 12) Validus’ 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; 13) general economic and market conditions (including inflation, volatility in the credit and capital markets, interest rates and foreign currency exchange rates); 14) the integration of businesses Validus may acquire or new business ventures Validus may start; 15) the effect on Validus’ investment portfolios of changing financial market conditions including inflation, interest rates, liquidity and other factors; 16) acts of terrorism or outbreak of war; and 17) availability of reinsurance and retrocessional coverage, 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 other documents on file with the Securities and Exchange Commission. Any forward-looking statements made in this news release are qualified by these cautionary statements, and there can be no assurance that the actual results or developments anticipated by us 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. We undertake no obligation to update publicly or revise any forward-looking statement, whether as a result of new information, future developments or otherwise. 2 INVESTOR PRESENTATION THIRD QUARTER 2011

Note on Non-GAAP Financial Measures In presenting the Company’s results herein, management has included and discussed certain schedules containing underwriting income (loss) available (attributable) to Validus, net operating income (loss) available (attributable) to Validus, annualized return on average equity and diluted book value per common share that are not calculated under standards or rules that comprise U.S. GAAP. Such measures are referred to as non-GAAP. Non-GAAP measures may be defined or calculated differently by other companies. We believe that these measures are important to investors and other interested parties. These measures should not be viewed as a substitute for those determined in accordance with U.S. GAAP. The underwriting results of an insurance or reinsurance company are often measured by reference to its underwriting income because underwriting income indicates the performance of the company’s core underwriting function. Underwriting income is reconciled to net income by the addition or subtraction of net investment income (loss), finance expenses, transaction expenses, net realized gains (losses) on investments, net unrealized gains (losses) on investments and foreign exchange gains (losses). Net operating income (loss) available (attributable) to Validus is calculated based on net income (loss) available (attributable) to Validus excluding net realized gains (losses), net unrealized gains (losses) on investments, gains (losses) arising from translation of non-US$ denominated balances and non-recurring items. Net income is the most directly comparable GAAP measure. Net operating income focuses on the underlying fundamentals of our operations without the influence of realized gains (losses) from the sale of investments, net unrealized gains on investments, translation of non-US$ currencies and non-recurring items. Realized gains (losses) from the sale of investments are driven by the timing of the disposition of investments, not by our operating performance. Gains (losses) arising from translation of non-US$ denominated balances are unrelated to our underlying business. Diluted book value per share is calculated based on total shareholders’ equity plus the assumed proceeds from the exercise of outstanding stock options and warrants, divided by the sum of unvested restricted shares, stock options, warrants and share equivalents outstanding (assuming their exercise). Reconciliations to the most comparable GAAP measure for both net operating income and diluted book value per share can be found at the end of this presentation. 3 INVESTOR PRESENTATION THIRD QUARTER 2011

The Property Catastrophe Rate Environment Continues to be Favorable... 11 1 Index value of 100 in 1990 Source: Guy Carpenter ...And is Recognized as an Attractive Growth Opportunity “Using RMS version 9 as a stable baseline to calculate the amount of risk in both this year's and last year's programs, and measuring the price change by unit of exposure to mitigate the impact of exposure changes, pricing shifted on average up 5 percent to up 10 percent, with a wide range of outcomes for individual programs.” - Guy Carpenter, 6/1/11 US Catastrophe Rate on Line Index1 “US property catastrophe rates have experienced a directional shift since January 2011, with increases due primarily to global losses and new versions of the catastrophe models.” - Guy Carpenter, 7/1/11 “While our competitors reportedly placed business at increased rates of as high as 15 percent, we drove flat to reduced pricing through to completion for U.S. property catastrophe program renewals... Our outlook for the pricing of U.S. property catastrophe renewals for the remainder of the year is flat assuming no additional occurrences of substantial insured and reinsured catastrophe losses. Clearly, however, the reinsurance market for renewals for the remainder of the year is more sensitive to additional losses this year than last given reinsured loss experience to date this year.” - Aon, July 2011 Rate increases at mid-year “New capacity was scarce and more expensive than renewal capacity, in particular for peak wind placements on nationwide accounts Percentage rate changes varied by layer with existing top layers in peak zones most heavily impacted; this was driven by increased cost of capital pressures due to international catastrophe losses, more expensive retrocessional costs and most noticeably, from increases in modeled losses for U.S. wind... Property rates: US Florida catastrophe loss free change -5% to +15%; US Nationwide catastrophe loss free change +5% to +15% / catastrophe loss hit change +10% to +20%” - Willis, 7/1/11

The estimates set forth above are based on an Occurrence basis on assumptions that are inherently subject to significant uncertainties and contingencies. These uncertainties and contingencies can affect actual losses and could cause actual losses to differ materially from those expressed above. In particular, modeled loss estimates do not necessarily accurately predict actual losses, and may significantly mis-estimate actual losses. Such estimates, therefore, should not be considered as a representation of actual losses. The Company has developed the estimates of losses expected from certain catastrophes for its portfolio of property, marine, workers’ compensation, and personal accident contracts using commercially available catastrophe models such as RMS, AIR and EQECAT, which are applied and adjusted by the Company. These estimates include assumptions regarding the location, size and magnitude of an event, the frequency of events, the construction type and damageability of property in a zone, policy terms and conditions and the cost of rebuilding property in a zone, among other assumptions. These assumptions will evolve following any actual event. Accordingly, if the estimates and assumptions that are entered into the risk model are incorrect, or if the risk model proves to be an inaccurate forecasting tool, the losses the Company might incur from an actual catastrophe could be materially higher than its expectation of losses generated from modeled catastrophe scenarios. In addition, many risks such as second-event covers, aggregate excess of loss, or attritional loss components cannot be fully evaluated using the vendor models. Further, the Company cannot assure that such third party models are free of defects in the modeling logic or in the software code. Investors should not rely on the information set forth in this presentation when considering investment in the Company. The information contained in this presentation has not been audited nor has it been subject to independent verification. The estimates set forth above speak only as of the date of this presentation and the Company undertakes no obligation to update or revise such information to reflect the occurrence of future events, including, but not limited to, the composition of the Company's business. The events presented reflect a specific set of proscribed calculations and do not necessarily reflect all events that may impact the Company.

Twice yearly, Lloyds' syndicates, including the Company's Talbot Syndicate 1183, are required to provide details of their potential exposures to specific disaster scenarios. Lloyds' makes its updated Realistic Disaster Scenarios (RDS) guidance available to the market annually. The RDS scenario specification document for 2011 can be accessed at the RDS part of the Lloyd's public website http://www.lloyds.com/The-Market/Tools-and-Resources/Research/Exposure-Management/Realistic- Disaster-Scenarios Modeling catastrophe threat scenarios is a complex exercise involving numerous variables and is inherently subject to significant uncertainties and contingencies. These uncertainties and contingencies can affect actual losses and could cause actual losses incurred by the Company to differ materially from those expressed above. Should an event occur, the modeled outcomes may prove inadequate, possibly materially so. This may occur for a number of reasons including, legal requirements, model deficiency, non-modeled risks or data inaccuracies.  A modeled outcome of net loss from a single event also relies in significant part on the reinsurance and retrocession arrangements in place, or expected to be in place at the time of the analysis, and may change during the year. Modeled outcomes assume that the reinsurance and retrocession in place responds as expected with minimal reinsurance failure or dispute. Reinsurance is purchased to match the original exposure as far as possible, but it is possible for there to be a mismatch or gap in cover which could result in higher than modeled losses to the Company. In addition, many parts of the reinsurance program are purchased with limited reinstatements and, therefore, the number of claims or events which may be recovered from second or subsequent events is limited. It should also be noted that renewal dates of the reinsurance program do not necessarily coincide with those of the inwards business written. Where original business is not protected by risks attaching reinsurance or retrocession programs, the programs could expire resulting in an increase in the possible net loss retained by the Company.
