Execution Copy STIPULATION AND AGREEMENT OF COMPROMISE AND SETTLEMENT This Stipulation and Agreement of Compromise and Settlement (the "Settlement Agreement"), dated June 20, 2013, which is entered into by, between and among (i) the Louisiana Municipal Police Employees Retirement System ("Plaintiff'), on behalf of itself as well as members of the Settlement Class (defined in paragraph 1(1)) and (ii) defendants W. Marston Becker, Michael O'Reilly, James D. Carey, Meryl D. Hartzband, Willis T. King, Jr., James L. Zech, Mario P. Torsiello, K. Bruce Connell, James H. Macnaughton, W. Thomas Forrester, Stephan F. Newhouse, Andrew H. Rush, Alterra Capital Holdings Limited ("Alterra"), Markel Corporation ("Markel"), and Commonwealth Merger Subsidiary Limited ("Merger Sub") which has merged with and into Alterra (collectively, the "Defendants," and collectively with the Plaintiff, the "Parties"), by and through their undersigned attorneys, states all of the terms of the settlement and resolution of the action entitled Louisiana Municipal Police Employees Retirement System v. Alterra Capital Holdings Limited et al., No. 13-cv-0933 (S.D.N.Y.) (the "Action"), and is intended by all of the Parties to fully and finally compromise, resolve, discharge and settle the Released Claims (defined in paragraph 16)) subject to the approval of the Court: BACKGROUND TO THE SETTLEMENT WHEREAS, the background to the Settlement (defined in paragraph 1(k)) is set forth in paragraphs A through J below: A. On December 19, 2012, Alterra and Markel announced a definitive merger agreement (the "Merger Agreement") pursuant to which each Alterra common share would be converted into the right to receive Markel common shares plus a cash payment of $10 per share (the "Transaction"); v2 I

Execution Copy B. On January 18, 2013, Alterra and Markel filed with the Securities Exchange Commission (the "SEC") a definitive proxy statement on Form DEFM14A relating to the Transaction (the "Proxy"); C. On February 8, 2013 the Plaintiff commenced Action in the United States District Court for the Southern District of New York (the "Court") as a putative class action against the Defendants alleging, among other things, that the Proxy misrepresents and/or omits material information necessary for Alterra's public shareholders to make an informed decision regarding whether to vote in favor of the Transaction; D. On February 13, 2013, Plaintiff filed a Motion for Preliminary Injunction seeking to enjoin the shareholder vote on the Transaction based on alleged deficiencies in the Proxy; E. On February 15, 2013, in response to the Plaintiff's demands for further disclosure to Alterra's shareholders and as a result of negotiations among the Parties, Alterra included certain additional and/or revised disclosures (the "Supplemental Disclosures"), substantially in the form of Exhibit A, in its Definitive Proxy Statement filed with the SEC (the "Definitive Proxy"). F. On or as of February 15, 2013, the Parties executed a Memorandum of Understanding ("MOU"). The MOU memorialized the terms of the Parties' agreement in principle to settle the Action. G. Defendants acknowledged that the pendency of the Action and the efforts of the Plaintiff's counsel caused their decision to include the Supplemental Disclosures in the Definitive Proxy to Alterra's shareholders. H. As further provided in the MOU, the Parties contemplated that the MOU v2 2

Execution Copy ultimately would be replaced by this Settlement Agreement, to be prepared by the Parties and submitted to the Court for approval, and that this Settlement Agreement would include all of the terms of the Settlement, including proposing the certification of a class for settlement purposes only. I. Prior to negotiating and entering into the MOU, the Plaintiff's counsel received productions of documents from Alterra which they reviewed and analyzed. The Plaintiff's counsel reserved the right to conduct additional discovery to confirm their, and the Plaintiff's, conclusion that the Settlement was fair, adequate, reasonable and in the best interests of the putative class (the "Confirmatory Discovery"). The Plaintiff's counsel deemed it appropriate and necessary to conduct Confirmatory Discovery before entering into this Settlement Agreement. The post-mou Confirmatory Discovery occurred and included the depositions of W. Marston Becker, the Chief Executive Officer of Alterra, and Robert Giammarco, a representative of Bank of American Merrill Lynch. Transaction. J. On February 26, 2013, shareholders of Alterra and Markel voted to approve the WHEREAS, the Defendants vigorously have denied, and vigorously continue to deny, all allegations of wrongdoing, fault, liability or damage with respect to each and all claims asserted in the Action, including that any of them has committed any violation of any law, rule or regulation; that any of them has acted improperly in any way; that any of them has breached any duty; and/or that any of them has any liability or owe any damages of any kind to the Plaintiff and/or the Settlement Class or any member thereof. The Defendants further deny that any of the provisions of the Supplemental Disclosures was or is required under any applicable law, rule or regulation, but are entering into this Settlement Agreement solely because they consider it v2 3

Execution Copy desirable that the Action be settled and dismissed with prejudice in order to, among other things, (i) eliminate the burden, inconvenience, expense, risk and distraction of further litigation, and (ii) finally put to rest and terminate all the claims that were or could have been asserted against any of the Defendant Releasees (defined in paragraph 1(c)). WHEREAS, the Plaintiff's counsel has reviewed and analyzed the facts and circumstances relating to the claims asserted and which could have been asserted in the Action, including conducting arm's-length discussions with counsel to the Defendants, analyzing documents produced by the Defendants and obtained through public sources, analyzing applicable case law and other authorities and conducting the Confirmatory Discovery. Based on these investigations and analyses, the Plaintiff has decided to enter into the Settlement Agreement and to settle the Action after taking into account, among other things, (i) their belief that the litigation of the Action and the Settlement already have delivered substantial benefits to the Settlement Class; (ii) the facts developed during discovery; (iii) the attendant risks of continued litigation and the uncertainty of the outcome of the Action; (iv) the conclusion reached by the Plaintiff and the Plaintiff's counsel that the Settlement upon the terms and provisions set forth in this Settlement Agreement is fair, reasonable, adequate and in the best interests of the Settlement Class; (v) the probability of success on the merits of the allegations made in the Action, including the uncertainty relating to proof of those allegations; and (vi) the desirability of permitting the Settlement to be consummated as provided by the terms of this Settlement Agreement. The Plaintiff believes that the claims asserted in the Action have merit. The Plaintiff and Plaintiff's Counsel have concluded that the Proxy with the Supplemental Disclosures resulting from the Settlement provided Alterra's shareholders with material information sufficient to cast a fully-informed vote with respect to the Transaction y2 4

If any of the foregoing events occur, the Defendants reserve the right to oppose certification of any class in any proceeding and to fully defend any proceeding, and, conversely, the Plaintiff reserves the right to move for certification of a class for all purposes.

TO DEFINITIVE JOINT PROXY STATEMENT/PROSPECTUS The supplemental information disclosed below should be read in conjunction with the definitive joint proxy statement/prospectus on Schedule 14A (the "definitive joint proxy statement/prospectus") filed with the Securities and Exchange Commission (the "SEC") by Alterra Capital Holdings Limited ("Alterra" or "the Company") on January 18, 2013, relating to the special meeting of stockholders of A/terra to be held on February 26, 2013 at 11:00 am. Atlantic time, at the A/terra House, 2 Front Street, Hamilton, MM 1/, Bermuda. At the special meeting, Alterra's stockholders will be asked to vote on, among other things, proposals related to the approval and adoption of the Agreement and Plan of Merger (the 'merger agreement"), dated as of December 18, 2012, among Alterra, Markel Corporation ("Markel") and Commonwealth Merger Subsidiary Limited, a Bermuda exempted company and a direct, wholly owned subsidiary of Markel ("Merger Sub"), providing for Merger Sub to merge with and into A/terra, with Alterra surviving the merger as a wholly-owned subsidiary of Markel (the "merger"). LITIGATION RELATED TO THE MERGER Alterra stockholder Louisiana Municipal Police Employees Retirement System filed a complaint in the United States District Court for the Southern District of New York, purportedly on behalf of itself and other stockholders of Altena, against Alterra, Alterra's board of directors, Markel, and Merger Sub, On February 15, 2013, the defendants entered into a memorandum of understanding with the plaintiff regarding the settlement of this action. In connection with the settlement, Alterra agreed to make certain supplemental disclosures to its stockholders. The Company believes that the claims in this action are without merit and that no further disclosure is required to supplement the definitive joint proxy statement/prospectus under applicable laws; however, to avoid the risk that the action may delay or otherwise adversely affect the consummation of the merger and to minimize the expense of defending such action, Alterra is voluntarily making the supplemental disclosures set forth below. The memorandum of understanding contemplates that the parties will enter into a stipulation of settlement. The stipulation of settlement will be subject to customary conditions, including court approval following notice to Alterra's stockholders. In the event that the parties enter into a stipulation of settlement, a hearing will be scheduled at which the United States District Court for the Southern District of New York will consider the fairness, reasonableness and adequacy of the settlement. If the settlement is finally approved by the court, it will resolve and release all claims in all actions that were or could have been brought challenging any aspect of the proposed merger, the merger agreement and any disclosure made in connection therewith (excluding claims for dissenters' rights under Bermuda Law), pursuant to terms that will be disclosed to Alterra's stockholders prior to final approval of the settlement. In addition, in connection with the settlement, the parties contemplate that plaintiffs counsel will file a petition in the United States District Court for the Southern District of New York for an award of attorneys' fees and expenses to be paid by Alterra or its successor. The settlement will not affect the consideration that Alterra's stockholders are entitled to receive in the merger. There can be no assurance that the parties will enter into a stipulation of settlement, or that the court will approve any proposed settlement. In such event, the proposed settlement as contemplated by the memorandum of understanding may be terminated.

Discounted Cash Flow Analysis. BofA Merrill Lynch performed a discounted cash flow analysis of Alterra to calculate the estimated present value of the standalone levered, after-tax free cash flows that Alterra was forecasted to generate during Alterra's fiscal years 2013 through based on the Alterra management forecasts. "Levered, after-tax free cash flows" is defined for this purpose as the portion of cash flows after the impact of interest expense and taxes that can be distributed to shareholders during Alterra's fiscal years 2013 through 2017 based on the Alterra management forecasts. BofA Merrill Lynch calculated terminal values for Alterra by applying terminal multiples of 0.80x to 1.00x to Alterra's December 31, 2017 estimated book value. For purposes of its discounted cash flow analysis. BofA Merrill Lynch included the impact of the issuance of shares related to annual expected stockbased compensation expense. The cash flows and terminal values were then discounted to present value as of December 31, 2012 using discount rates ranging from 8% to 10%, which were based on an estimate of Alterra's cost of equity.
