PROXY STATEMENT
ANNUAL GENERAL MEETING OF SHAREHOLDERS

Unless otherwise indicated or unless the context otherwise requires, all references in this Proxy Statement to “Alterra Capital,” “we,” “us,” “our” and similar expressions are references to Alterra Capital Holdings Limited. Unless otherwise indicated or unless the context otherwise requires, all references in this Proxy Statement to the names of our direct and indirect subsidiaries are as set forth in the Glossary of Names as set forth in Annex A to this Proxy Statement.

This Proxy Statement is furnished in connection with the solicitation by the board of directors of Alterra Capital of proxies for use at the Annual General Meeting of Shareholders, which we refer to as the Meeting, of Alterra Capital to be held at Tucker’s Point, Verdmont Room, 60 Tucker’s Point Drive, Hamilton Parish HS 02, Bermuda on August 3, 2010 at 5:00 p.m. Atlantic Time, and at any and all adjournments or postponements thereof, for the purposes set forth in the accompanying Notice of Annual General Meeting of Shareholders.

On or about June [ ], 2010, Alterra Capital first sent a Notice of Internet Availability of Proxy Materials, which we refer to as the Notice, to shareholders who hold shares in “street name” through a bank, broker or other holder of record. On or about June [ ], 2010, Alterra Capital first sent this Proxy Statement and the accompanying Notice of Annual General Meeting of Shareholders to registered shareholders and beneficial holders who had previously opted out of Notice delivery. On February 16, 2010, Alterra Capital filed an Annual Report on Form 10-K for the fiscal year ended December 31, 2009, which we refer to as the Annual Report, with the Securities and Exchange Commission, which we refer to as the SEC. On March 12, 2010, Alterra Capital filed an Amendment to the Annual Report on Form 10-K/A with the SEC. All shareholders have the ability to access (i) this Proxy Statement and (ii) the Annual Report by (x) accessing the website referred to in the Notice, (y) accessing the website specified in the accompanying proxy voting card or (z) requesting a printed set of these materials at no charge. Instructions on how to access these materials over the internet may be found in the Notice or the proxy voting card. To request a printed copy of these materials, please write to us at our principal executive offices located at the address above.

VOTING SECURITIES AND VOTE REQUIRED

As of June 15, 2010, the record date for the determination of persons entitled to receive notice of and to vote at the Meeting, there were 119,677,612 common shares issued and outstanding, US$1.00 par value per share, of Alterra Capital, which we refer to as the common shares. The common shares are our only class of equity securities outstanding and entitled to vote at the Meeting or any and all adjournments or postponements thereof.

Each common share held by a shareholder entitles such shareholder to one vote on each matter that is voted upon by poll at the Meeting or any adjournments or postponements thereof, subject to certain provisions of our bye-laws that reduce the total voting power of any United States, or U.S., shareholder owning, directly or indirectly, beneficially or otherwise, 9.5% or more of the common shares to less than 9.5% of the total voting power of our capital stock unless otherwise waived at the discretion of our board of directors. In addition, our board of directors may limit a shareholder’s voting rights where it deems it necessary to do so to avoid adverse tax, legal or regulatory consequences.

The reduction of such voting power may have the effect of increasing another shareholder’s voting power to more than 9.5%, thereby requiring a corresponding reduction in such other shareholder’s voting power. Because the applicability of the voting power reduction provisions to any

particular shareholder depends on facts and circumstances that may be known only to the shareholder or related persons, we request that any holder of common shares with reason to believe that it is a shareholder whose common shares constitute 9.5% or more of the voting power of Alterra Capital, each of which we refer to as a 9.5% Shareholder, contact us promptly so that we may determine whether the voting power of such holder’s common shares should be reduced. By submitting a proxy, a holder of common shares will be deemed to have confirmed that, to its knowledge, it is not, and is not acting on behalf of, a 9.5% Shareholder. The directors of Alterra Capital are empowered to require any shareholder to provide information as to that shareholder’s beneficial ownership of common shares, the names of persons having beneficial ownership of the shareholder’s common shares, relationships with other shareholders or any other facts the directors may consider relevant to the determination of the number of common shares attributable to any person. The directors may disregard the votes attached to common shares of any holder who fails to respond to such a request or who, in their judgment, submits incomplete or inaccurate information. The directors retain discretion to make such final adjustments that they consider fair and reasonable in all the circumstances as to the aggregate number of votes attaching to the common shares of any shareholder to ensure that no person shall be a U.S. 9.5% Shareholder at any time.

The presence, in person or by proxy, of the holders of more than 50% of the issued and outstanding voting common shares as of June 15, 2010, the record date of the Meeting, is necessary to constitute a quorum at the Meeting. Assuming that a quorum is present, the affirmative vote of a majority of the votes cast at the Meeting will be required to approve each of the matters to be voted upon at the Meeting.

With regard to any proposal, votes may be cast in favor of or against such proposal or a shareholder may abstain from voting on such proposal. Abstentions will be excluded entirely from the vote and will have no effect except that abstentions and “broker non-votes” will be counted toward determining the presence of a quorum for the transaction of business.

SOLICITATION AND REVOCATION

PROXIES IN THE FORM ATTACHED ARE BEING SOLICITED BY, OR ON BEHALF OF, THE BOARD OF DIRECTORS. THE PERSONS NAMED IN THE ATTACHED FORM OF PROXY HAVE BEEN DESIGNATED AS PROXIES BY THE BOARD OF DIRECTORS. Such persons designated as proxies are officers of Alterra Capital. Any shareholder desiring to appoint another person to represent him or her at the Meeting may do so by inserting such person’s name in the blank space provided on the attached form of proxy and delivering an executed proxy to the Secretary of Alterra Capital at the address indicated above before the time of the Meeting. It is the responsibility of the shareholder appointing such other person to represent him or her to inform such person of this appointment.

All common shares represented by properly submitted proxies that are not revoked will be voted in accordance with the instructions, if any, given thereon. If no instructions are provided in a properly submitted proxy, it will be voted “FOR” each of the proposals described herein and set forth on the accompanying form of proxy, and in accordance with the proxy holder’s best judgment as to any other business as may properly come before the Meeting. If a shareholder appoints a person other than the persons named in the accompanying form of proxy to represent him or her, such person should vote the shares in respect of which he or she is appointed proxy holder in accordance with the directions of the shareholder appointing him or her.

Proxies should be received by us prior to August 2, 2010 at 1:00 p.m. Atlantic Time. A shareholder may revoke his or her proxy at any time up to one hour prior to the commencement of the Meeting by filing a written revocation with the Secretary of Alterra Capital at our address set forth above, by delivering a properly submitted proxy bearing a later date or by appearing in person and voting by ballot at the Meeting. A shareholder may vote his or her shares in person even if the shareholder has submitted a proxy.

Composition, Meetings and Committees of the Board of Directors

Our board of directors currently has 14 members, twelve of whom the board of directors has affirmatively determined, by resolution of the board of directors as a whole, are not officers or employees of Alterra Capital or its subsidiaries or individuals having a relationship that, in our board of directors’ opinion, would interfere with the exercise of independent judgment in carrying out the responsibilities of a director, and are therefore considered “independent” in accordance with Nasdaq Global Select Market listing standards. The directors that our board of directors has determined to be independent in accordance with the foregoing standards are Ms. Hartzband and Messrs. Carey, Cheesbrough, Connell, Forrester, King, MacNaughton, Newhouse, O’Reilly, Rush, Torsiello and Zech. The position of Chairman is held by Mr. O’Reilly, an independent director. Mr. Becker serves as our Chief Executive Officer.

Our board of directors is substantially composed of independent directors in that only two of our directors and nominees are considered not independent. Further, at each regularly scheduled board meeting, the independent directors conduct an executive session without management and management directors. In addition, our key committees are composed solely of independent directors, namely the (i) Compensation Committee, (ii) Audit and Risk Management Committee, which we refer to as the ARMC, and (iii) Nominating and Corporate Governance Committee. These directors have diligently exercised their fiduciary duties in monitoring the operations of the Company.

The board of directors has established six committees, consisting of the ARMC; Compensation Committee; Executive Committee; Finance and Investment Committee; Nominating and Corporate Governance Committee; and Underwriting/Risk Management Committee. The board of directors has adopted a charter for each of its committees, each of which is posted on our website at www.alterracap.com. The current members of the committees are identified in the table below:

Each of our directors then in office attended in person, or by telephone from outside of the United States, at least 75% of the total number of meetings of the board of directors and any committee on which he served. It is our policy that directors are expected to attend the annual general meeting of shareholders in the absence of a scheduling conflict or other valid reason. All but two of our directors then in office (including one director who was not standing for re-election at the meeting) attended in person the 2009 annual general meeting of shareholders held on November 2, 2009.

Audit and Risk Management Committee

Each of the directors comprising the ARMC has been determined by the board of directors to be independent in accordance with Nasdaq Global Select Market listing standards and applicable rules and regulations promulgated under the Securities Exchange Act of 1934, as amended, which we refer to as the Exchange Act. The ARMC is governed by a written charter approved by our board of directors. The primary purpose of the ARMC is to assist the board of directors in (i) overseeing the integrity of our financial statements, (ii) overseeing our system of disclosure controls and procedures, internal controls over financial reporting and compliance with ethical standards adopted by us, (iii) overseeing the independent auditor’s qualifications, independence and performance, (iv) overseeing the performance of our internal audit function and independent auditors, (v) overseeing our compliance with legal and regulatory requirements and (vi) performing such other duties as our board of directors may from time to time delegate to it. The ARMC also discusses with management our major financial risk exposures and the steps management has taken to monitor and control such exposures, including our risk assessment and risk management policies. Mr. Torsiello has been designated as our “audit committee financial expert” as defined in Section 407 of the Sarbanes-Oxley Act of 2002.

10

Compensation Committee

Each of the directors comprising our Compensation Committee has been determined by the board of directors to be independent in accordance with Nasdaq Global Select Market listing standards. Our Compensation Committee (i) discharges, as delegated by our board of directors, the board of directors’ responsibilities relevant to compensation of our Chief Executive Officer, (ii) reviews, approves and determines non-Chief Executive Officer remuneration, including compensation, incentive-compensation and equity-based compensation, (iii) produces a committee report on executive compensation and reviews the disclosures in the Compensation Discussion and Analysis as required by the SEC to be included in this Proxy Statement, (iv) administers our equity based compensation plans and (v) performs such other functions as the board of directors may from time to time assign to it. Our Compensation Committee may delegate these responsibilities to subcommittees comprised of one or more members of the Compensation Committee, our board of directors, members of management, employees or other service providers if the Compensation Committee determines such delegation would be in the best interest of the Company and permissible under applicable listing standards.

Under the Alterra Capital Holdings Limited 2008 Stock Incentive Plan, which we refer to as our 2008 Incentive Plan, our Compensation Committee has the authority to grant Awards (as defined in our 2008 Incentive Plan to include incentive stock options, nonqualified stock options, restricted stock, restricted stock units, stock appreciation rights, stock bonus awards and performance compensation awards) to eligible participants. Our 2008 Incentive Plan was approved by our shareholders at the May 2008 annual general meeting. The 2008 Incentive Plan replaces the Alterra Capital Holdings Limited 2000 Incentive Plan, which we refer to as the 2000 Incentive Plan, which, together with our 2008 Incentive Plan, we refer to as our Incentive Plans. Unused shares under the 2000 Incentive Plan are used only to meet the Company’s obligations incurred pursuant to the 2000 Incentive Plan prior to the effectiveness of our 2008 Incentive Plan.

In connection with the amalgamation on May 12, 2010, we assumed the Harbor Point Limited Amended and Restated 2006 Equity Incentive Plan, which was renamed the Alterra Capital Holdings Limited 2006 Equity Incentive Plan and which we refer to as the 2006 Incentive Plan. Outstanding shares and awards under the 2006 Incentive plan were adjusted in accordance with the terms of the amalgamation agreement. Our Compensation Committee has the authority to grant awards (as defined under the 2006 Incentive Plan to include incentive stock options, nonqualified stock options, stock appreciation rights and restricted stock awards) to eligible participants, which include our affiliate’s employees, directors and consultants. Awards may not be granted under the 2006 Incentive Plan to individuals who were employed by Max Capital Group Ltd. or its subsidiaries prior to the consummation of the amalgamation.

Our Compensation Committee also reviews and approves contractual employment and compensation arrangements with executive officers and other members of senior management and oversees the administration of our employee benefits and benefit plans.

Executive Committee

During the intervals between meetings of our board of directors, the Executive Committee may exercise the powers of the board of directors to act upon any matters that, in the opinion of the Chairman of our board of directors, should not be postponed until the next scheduled meeting of the board of directors. The Executive Committee is precluded from acting on matters that are (i) deemed impermissible for the Executive Committee to act upon by our memorandum of association and bye-laws, applicable law, regulation or stock exchange rules or (ii) properly reserved to the board of directors or to another committee of the board of directors. Actions or meetings by our Executive Committee have been limited due to the frequency of our board of directors’ meetings and the delegation of certain board responsibilities to other committees of our board of directors.

11

Finance and Investment Committee

The Finance and Investment Committee oversees our board of directors’ responsibilities relating to our financial affairs and makes recommendations to the board of directors in connection with our investment guidelines, investment asset allocations and financing activities. As part of this function, the Finance and Investment Committee also reviews and makes recommendations regarding our dividend policy, share repurchase program, capital expenditure budgets, corporate acquisitions, divestitures and joint ventures.

Nominating and Corporate Governance Committee

Each of the directors comprising our Nominating and Corporate Governance Committee has been determined by our board of directors to be independent in accordance with Nasdaq Global Select Market listing standards. The Nominating and Corporate Governance Committee (i) identifies individuals qualified to become members of the board of directors, (ii) recommends to the board of directors individuals to serve as directors and on committees of the board of directors, (iii) advises the board of directors with respect to board composition, procedures and committees, (iv) evaluates and makes recommendations to the board of directors with respect to the compensation of directors, (v) develops and recommends to the board of directors a set of corporate governance principles for us, (vi) oversees the evaluation of the board of directors, (vii) develops succession planning for our executive officers and (viii) has such other powers and performs such other duties as our board of directors may from time to time delegate to it.

The Nominating and Corporate Governance Committee’s goal is to recommend individuals that have high ethical standards combined with the experience and expertise that, when added to the experience and expertise of the other members of our board of directors, will result in the board of directors as a whole having experience and expertise in the various areas within which our board of directors is called to operate. Candidates for director are selected based upon various criteria, including their knowledge, experience, skills, expertise and diversity of such characteristics so as to enhance the ability of our board of directors to manage and direct our affairs including, when applicable, to enhance the ability of committees of our board of directors to fulfill their respective duties and/or to satisfy the independence requirements imposed by law, regulation or NASDAQ standards. The Nominating and Corporate Governance Committee and our board of directors review these factors in considering candidates for board of directors’ membership.

The Nominating and Corporate Governance Committee will consider nominees recommended by shareholders. There is no difference between the manner in which a director nominee is evaluated based on whether such nominee is recommended by the Nominating and Corporate Governance Committee or by a shareholder. Any shareholder wishing to nominate a candidate for director at a shareholders’ meeting must submit a proposal as described under “Additional Information—Shareholder Proposals for Annual General Meeting of Shareholders in 2011” and furnish certain information about the proposed nominee. Candidates must have a minimum of 10 years of executive level experience, but otherwise there are no minimum requirements for nominees. The shareholder submission should be addressed to the Secretary of Alterra Capital at Alterra House, 2 Front Street Hamilton HM 11, Bermuda. There have been no modifications to the procedure by which security holders may recommend nominees since we last provided this disclosure.

Underwriting/Risk Management Committee

Our Underwriting/Risk Management Committee was established in May 2010 and advises our board of directors and management concerning the establishment and review of our underwriting policies and guidelines, oversees the underwriting process and procedures, monitors underwriting performance and oversees underwriting risk management exposure.

12

Additional Committee Members

Additional committee members may be added from time to time. The composition of any or all committees may change, subject to the results of elections of directors at shareholders’ meetings or for other reasons. Additionally, we may from time to time form other committees as circumstances warrant. Such committees will have the authorities and responsibilities as delegated by our board of directors.

Shareholder Communications

We have adopted a formal process by which shareholders may communicate directly to directors, in which any communication sent to a director or directors in care of the Secretary of Alterra Capital at Alterra House, 2 Front Street Hamilton HM 11, Bermuda is forwarded to the specified director or directors. There is no screening process, other than to confirm that the sender is a shareholder, and all shareholder communications that are received by the Secretary of Alterra Capital for the attention of a director or directors are forwarded to the director or directors, with a copy to the chairman of the ARMC.

Board Leadership Structure and Role in Risk Oversight

We separate the roles of Chief Executive Officer and Chairman in recognition of the differences between the two roles. Our Chief Executive Officer is responsible for setting the strategic direction for the Company and the day to day leadership and performance of the Company, while the Chairman of the Board of Directors provides guidance to the Chief Executive Officer and sets the agenda for our board of directors meetings and presides over meetings of our full board of directors. Our Chief Executive Officer serves on our board of directors, which we believe helps Mr. Becker serve as a bridge between management and our board of directors, ensuring that both groups act with a common purpose. We believe that the Mr. Becker’s presence on our board of directors enhances his ability to provide insight and direction on important strategic initiatives to both management and the independent directors and, at the same time, ensures that the appropriate level of independent oversight is applied to all decisions by our board of directors.

Although our board of directors has ultimate responsibility with respect to risk management oversight, primary responsibility for oversight of certain areas has been delegated to the ARMC. Our ARMC is charged with, among other matters, overseeing risks attendant to (i) our system of disclosure controls and procedures, (ii) financial reporting, (iii) compliance with legal and regulatory requirements, (iv) financial exposures and (v) performance of our internal audit functions and independent auditors. Our ARMC considers the steps management has taken to monitor and control such risks, including our risk assessment and risk management policies. In addition, each of our board committees considers the risks within its area of responsibilities. For example, our Compensation Committee considers risks that may be implicated by our executive compensation programs.

Change in Control

On March 3, 2010, Alterra Capital (formerly Max Capital Group Ltd.), Alterra Holdings and Harbor Point entered into an Amalgamation Agreement pursuant to which Alterra Holdings amalgamated with Harbor Point, effective May 12, 2010. Under the terms of the Amalgamation Agreement, holders of Harbor Point common shares each received a fixed exchange ratio of 3.7769 common shares of Alterra Capital for each Harbor Point common share. Alterra Capital issued 62,479,273 shares to former holders of Harbor Point Class A voting common shares pursuant to Alterra Capital’s obligations under the Amalgamation Agreement. Following the close of the amalgamation on May 12, 2010, the former holders of Harbor Point common shares owned approximately 52% of Alterra Capital’s outstanding common shares.

Certain Relationships and Related Transactions

Policies and Procedures Dealing with the Review, Approval and Ratification of Related Party Transactions

In February 2008, the ARMC adopted a written policy, which was approved by our board of directors and replaced the ARMC’s prior policy, for the review, approval and ratification of transactions with related persons. The policy covers related party transactions between us and any of our executive officers and directors or their affiliates, director nominees, 5% security holders and family members of any of the foregoing. Related party transactions covered by this policy are reviewed by the ARMC to determine whether the transaction is in the best interests of our Company and our shareholders. Subsequent to the adoption of the policy above, we have followed this policy regarding all reportable related party transactions.

Described below are transactions we have entered into with parties that are related to us. We believe that each of the transactions described below was on terms no less favorable to us than we could have obtained from unrelated parties.

Transactions and Relationships with Directors and their Affiliates

Mr. Zack Bacon was a director of Alterra Capital from July 1999 to November 2009 and a member of the Executive Committee and the Finance and Investment Committee of our board of directors, which is responsible for, among other things, making recommendations to our board of directors regarding the selection of investment managers and custodians for our investable assets.

Alstra Capital Management, LLC, an affiliate of Mr. Bacon, which we refer to as Alstra, served as fund of funds advisor for Alterra Diversified from April 1, 2004 through January 2009. In consideration of the reduced allocation to alternative investments, the Company determined it prudent to manage Alterra Diversified’s investments internally. Accordingly, we hired certain key personnel from Alstra and terminated the services agreement with Alstra effective January 31, 2009. The research staff hired from Alstra assists in internal management of both our traditional and alternative investment portfolios. For the year ended December 31, 2009, Alstra received $700,000 in fees as the fund of funds advisor for Alterra Diversified and a termination fee of $2.0 million upon termination of the advisor relationship.

Alterra Diversified had approximately $8.5 million invested in funds managed directly by Moore Capital or its affiliates and approximately $303.6 million invested in other funds as of December 31, 2009. Moore Capital received aggregate management and incentive fees of $2.0 million in respect of Alterra Diversified’s assets invested in underlying funds managed by Moore Capital or its affiliates for the year ended December 31, 2009.

Asset Allocation and Management Company, L.L.C., which we refer to as “AAM,” provides asset management services to the Company pursuant to an agreement originally entered into on June 26, 2003. Each of Mr. Carey and Ms. Hartzband, current board members of Alterra Capital, is a member of the investment committee of, and the owner of one of the five general partners of, the sole general partner of Trident IV L.P., a private equity fund managed by Stone Point Capital LLC. Trident IV L.P. owns a majority of the equity of AAM and Mr. Carey is the chairman of the board of directors of AAM. For the year ended December 31, 2009, the Company made payments to AAM in the amount of $0.5 million.

As an insurer and reinsurer with clients worldwide, in the ordinary course of business, we routinely enter into insurance and reinsurance transactions with entities affiliated with our directors.

Transactions with Grand Central Re

Mr. Minton, our Chief Operating Officer, became a director of Grand Central Re in 2006. Mr. Roberts, our Chief Financial Officer, became President of Grand Central Re in April 2007. Alterra Managers and Grand Central Re entered into an insurance management agreement as of May 10, 2001, for which Alterra Managers received fees of $0.8 million in the year ended December 31, 2009.

Alterra Insurance entered into a quota share retrocession agreement with Grand Central Re, effective as of January 1, 2002, that required each of Alterra Insurance and Grand Central Re to retrocede a portion of their respective gross premiums written from certain transactions to the other party in order to participate on a co-insurance basis. Effective January 1, 2004, the quota share arrangement with Grand Central Re was amended to suspend any new business. In December 2004, Grand Central Re applied to the Bermuda Monetary Authority to change its status from a Class 4 composite insurer to a Class 3 composite insurer and currently has no plans to continue business.

Shareholders’ Agreements and Registration Rights

Pursuant to a shareholders’ agreement dated as of December 22, 1999, Moore Holdings was entitled to require us to register their holdings of our common shares under the Securities Act of 1933, as amended. Moore Holdings was permitted to demand registrations subject to certain conditions set forth therein. The shareholders’ agreement also provided certain shareholder piggyback rights to include their shares in registration statements covering shares to be offered by Alterra Capital or other shareholders, subject to cutbacks as further described in the shareholders’

18

agreement. In connection with the amalgamation, on March 3, 2010, Alterra Capital, Moore Holdings and Moore Global Investments, Inc., which we refer to as MGI, entered into a consent, termination and release agreement with respect to this shareholders’ agreement, pursuant to which the parties agreed to, effective as of the closing of the amalgamation, (1) terminate this existing shareholders’ agreement as it pertains to their rights and obligations thereunder and (2) consent to Alterra Capital granting certain registration rights to Harbor Point shareholders.

Upon the closing of the amalgamation on May 12, 2010, Alterra Capital entered into a registration rights agreement with each of Moore Holdings, MGI, Remington Investment Strategies, L.P., which we refer to as Remington, Chubb and the Trident Funds, whereby each shareholder is entitled to require us to file a registration statement covering the offering and sale of all or any portion of its Alterra Capital shares subject to the registration rights agreement, which we refer to as the registerable securities, and use commercially reasonable efforts to effect, as expeditiously as possible, the registration of the registerable securities. Each party to the registration rights agreement holding registerable securities will have ten business days from receipt of our notice of any such demand registration to request that we register its registerable securities in such demand registration.

Under the registration rights agreement, we may avoid a demand registration if (1) the aggregate gross proceeds expected to be received from the sale of the registerable securities requested to be included in such demand registration is less than $25 million; (2) more than two demand registrations are made by each of (a) MGI, Remington and Moore Holdings and their affiliates, (b) The Trident Funds and their affiliates and (c) Chubb and its affiliates; or (3) more than one demand registration is made within any four-month period is made.

Warrant Waivers

In connection with the amalgamation, on May 12, 2010 Alterra entered into amendments and restatements of each of the warrants held by Moore Holdings, to cause the anti-dilution provisions in such warrants to be amended, to conform to the anti-dilution provisions set forth in the Harbor Point warrants. Among other things, the amended and restated warrants entitle Moore Holdings to receive, in the event of any cash dividends by us, an adjustment to the warrant exercise price and the number of shares issuable upon exercise of such warrants or, in lieu of such adjustments, cash upon exercise in an amount that Moore Holdings would have been entitled to receive had it exercised its warrants immediately prior to the record date for such cash dividend.

Because of a “most favored nations” provision in the warrants held by certain employees of Alterra (including Mr. Minton), such employees will be entitled to the same amendments as are made to the Moore Holdings amended and restated warrants. On March 3, 2010, Mr. Minton agreed to waive the right to receive an adjustment to the exercise price of his warrants following the payment by the combined company of cash dividends. Instead, pursuant to the terms of this waiver, in the event of any cash dividends by the combined company, Mr. Minton will only be entitled to cash payments at the time of exercise in the amount he would have received had he exercised his warrants immediately prior to the record date for such cash dividends.

Waiver of Equity Vesting

In connection with the amalgamation, equity awards for Messrs. Becker, Roberts, Minton, Guagliano and Mullan evidencing stock options, restricted shares or restricted share units (with the exception of those equity awards granted after December 31, 2009) would have vested on May 12, 2010. Notwithstanding this right to accelerated vesting, each of Messrs Becker, Roberts, Minton, Guagliano and Mullan agreed to waive 100% of the accelerated vesting of these equity awards, which we refer to as the affected awards. Therefore, the affected awards did not vest in connection with the amalgamation and will remain subject to their original vesting requirements, except all affected awards will become fully vested upon the applicable named executive officer’s death or termination of employment without “Cause” or due to “Disability,” or by the named executive officer for “Good Reason” (as those terms are defined in the applicable named executive officer’s

19

employment agreement or in the applicable Incentive Plan). In the event of the named executive officer’s Retirement (as defined in the applicable Incentive Plan or the award agreement), the affected awards will continue to vest in accordance with their current terms.

Notwithstanding his entry into the vesting waiver agreement discussed above, Mr. Guagliano resigned from the Company effective May 31, 2010 pursuant to Section 6(d) of his employment agreement with Alterra Insurance Limited. As a result, all of Mr. Guagliano’s affected awards vested on that date.

Lock-Up Agreements

In connection with the Amalgamation Agreement, on March 3, 2010, Alterra Capital and Harbor Point entered into lock-up agreements with certain Alterra Capital shareholders and Harbor Point shareholders, who would be continuing directors, members of senior management and certain significant shareholders of the combined company.

Each shareholder executing a lock-up agreement agreed that for a period beginning on March 3, 2010 and ending 180 days following the May 12, 2010, the effective time of the amalgamation, such shareholder will not offer or agree to, directly or indirectly sell, transfer, assign or otherwise dispose of or enter into any derivative, hedging or other similar agreement with respect to or related to, any common shares, options or warrants owned by such person, subject to certain customary exceptions. Each such shareholder has also agreed to be bound by the non-solicitation provisions of the Amalgamation Agreement.

Indemnification Agreements

We have entered into indemnification agreements with certain former directors, our current directors and certain current and former officers, pursuant to which, among other things, we have agreed to provide contractual indemnification that supplements the indemnification contained in our bye-laws and to indemnify and provide advancement of expenses to such directors and officers in respect of all liabilities paid in settlement of or in connection with any claim based on the fact that such director or officer is or was a director or officer of the Company.

Ownership and Voting Limitations

Pursuant to Alterra Capital’s bye-laws, less than 9.5% of our common shares may be owned by any person, which we refer to as the Ownership Limitation, or voted by any U.S. shareholder, which we refer to as the Voting Limitation, unless otherwise waived by our board of directors.

Compensation Philosophy and Objectives

To accomplish our primary strategic objective of increasing shareholder wealth over the long term, our Compensation Committee believes that:

• we should hire above average talent and provide above average compensation for above average productivity and results. We strive to do more with fewer people;

• our compensation program must be competitive with peer companies in our industry in order to ensure that we can attract, retain and motivate the key individuals necessary to lead our Company;

• the most effective compensation program is one that rewards the achievement of both short-term and long-term goals and that aligns the interests of our executives with those of our shareholders;

• short-term compensation should be comprised of a mix of base salary and an annual bonus opportunity that links pay with performance results; and

• long-term compensation should be comprised of equity awards to ensure sustained alignment to shareholders’ interests.

These are the guiding principles on which we rely when developing compensation programs in support of our business strategy.

Role of Compensation Committee and Management in Compensation Decisions

Our Compensation Committee works closely with our Chief Executive Officer and other members of his leadership team in managing our compensation programs. Our Compensation Committee is generally responsible for reviewing and approving all compensation decisions with regard to our named executive officers, including:

• establishing, implementing and monitoring adherence to our compensation philosophy and objectives;

• approving all incentive program design and incentive goals;

• approving all incentive plan pools;

• reviewing all recommendations made with respect to discretionary compensation and approving all discretionary compensation decisions, including base salary, bonus targets, bonus payments and long-term incentive awards;

• evaluating Company, operating segment and individual performance;

• evaluating compensation levels in comparison to our peers; and

• approving all equity compensation awards.

Our Chief Executive Officer and certain members of his leadership team (including Messrs. Minton and Roberts) have a role in supporting the Compensation Committee, including responsibility for:

• providing information with respect to Company, operating segment, and individual performance to assist our Compensation Committee in its analysis and evaluation of the compensation of our named executive officers;

• providing information with respect to compensation levels in comparison to our peers;

• developing compensation program design recommendations in support of business strategy, including incentive program design and incentive goals;

• developing recommendations for discretionary compensation decisions, including base salary, bonus targets, bonus payments and long-term incentive awards; and

• executing Compensation Committee decisions and other administrative tasks delegated from the Compensation Committee.

21

Our Chief Executive Officer, together with our senior human resources officer, is responsible for making compensation recommendations to the Compensation Committee, including salary, bonus and long-term incentive recommendations for the named executive officers other than the Chief Executive Officer. Compensation discussions and recommendations most often occur at the regularly scheduled meetings of the Compensation Committee, but our Chief Executive Officer and senior human resources officer do from time to time hold discussions between meetings with the Chairman of our Compensation Committee. Our Compensation Committee gives considerable weight to our Chief Executive Officer’s recommendations and will frequently approve his recommendations as submitted. However, the Compensation Committee has complete authority to make decisions other than what has been recommended, and it is ultimately responsible for all compensations decisions concerning our named executive officers, including our Chief Executive Officer.

Role of Compensation Consultants

The Compensation Committee may from time to time engage an independent compensation consultant for special projects. No such consultant was hired for 2009.

Role of Peer Company Analysis

The competitiveness of our compensation is evaluated against other Bermuda and U.S. companies with which we compete, with adjustments where appropriate to reflect our offshore locations. In 2009, we relied primarily on a database provided by Equilar, Inc., which aggregates information from proxy statements and other documents filed with the SEC to analyze compensation data (including base salary, bonus compensation and equity awards). This information assisted the Compensation Committee in analyzing the compensation received by our Chief Executive Officer and other executive officers in comparison to our peer companies set forth below and other similarly situated publicly traded companies. In 2009, the peer company group identified by our Compensation Committee consisted of:

2009 Peer Companies
•	Allied World Assurance Company, Ltd.	•	Everest Re Group, Ltd.
•	Arch Capital Group Ltd.	•	Montpelier Re Holdings Ltd.
•	Aspen Insurance Holdings Limited	•	Platinum Underwriters Holdings, Ltd.
•	AXIS Capital Holdings Limited	•	Transatlantic Holdings, Inc.
•	Endurance Specialty Holdings Ltd.	•	Validus Holdings, Ltd.

These companies were selected because of their similarities to us, in the aggregate, with respect to lines of business, organizational size and operational history. In addition, we used data from the 2008 PricewaterhouseCoopers Bermuda International Business Compensation Survey, a third party compensation survey consisting of 64 companies, including insurance, reinsurance and captive insurers based in Bermuda. We used information from this survey as a secondary reference to substantiate the findings from the Equilar database with respect to our Chief Executive Officer and other executive officers. For making its compensation decisions with regard to Messrs. Becker, Roberts, Minton and Guagliano, our Compensation Committee relied exclusively on the peer data from Equilar, Inc. With respect to Mr. Mullan, his compensation was also benchmarked against data in the Watson Wyatt Survey on Lloyd’s Syndicates, which reports compensation data from insurance and reinsurance companies participating in the Lloyd’s market. We used a subset of companies from this survey representing companies (the identity of which was not provided to us) that had a similar size and scope as our Alterra at Lloyd’s subsidiary.

Based on a review of these outside sources, our Compensation Committee determined that, overall, our current compensation structure was competitive and aligned with the interests of our shareholders. For certain executive positions, however, the market review indicated that the level of our compensation was not competitive, particularly with respect to base salary. This review and the action taken by the Compensation Committee as a result are described in more detail under the Base Salary section below.

22

Components of Compensation Program

The principal components used to compensate our named executive officers and their primary purpose are summarized in the table below:

Compensation Component	Purpose
Base Salary	Attract and retain the executive talent we need to lead the Company
Annual Bonus	Link compensation to performance results
Long-Term Incentives	Link compensation to performance results and align the long-term interests of management with those of our shareholders
Employee Benefits	Attract and retain the executive talent we need to lead the Company

In addition to the above, based on jurisdictional practices, we may provide certain of our named executive officers with an automobile allowance, reimbursement for country club dues, housing allowance, certain tax gross-ups, special equity and performance awards, and such other employee benefit plans and programs and perquisites as we may from time to time maintain for the benefit of our employees. We have also entered into employment agreements with certain of our named executive officers in order to set forth the terms and conditions of their employment and to provide certain protections to both parties in the event of a termination of employment or a change in control. These agreements provide severance and change in control benefits to our executives. While we intend to maintain our current compensation, benefit and perquisite programs for our named executive officers, our Compensation Committee may revise, amend, or add to these benefit programs at its discretion.

More information concerning each of these components is set forth below.

Compensation Component Mix: We generally look at the mix of compensation paid to our executives, including our named executive officers, from two broad vantage points:

• Base Salary vs. Performance Bonuses: We provide cash compensation in the form of base salary to attract and retain qualified personnel. For experienced executives, including our named executive officers, we target base salary at a competitive level that is at or slightly below market median, and target performance bonus opportunities for both annual and long-term awards at above average levels for above average results. This desired mix between base pay and performance incentives is intended to create an environment in which our success affects a significant portion of each employee’s pay, in particular for our executives, and to focus attention on achievement of key business goals.

• Annual vs. Long-Term Bonuses: We provide compensation in the form of performance bonuses to focus attention on the achievement of key business goals and to align the interests of management with those of our shareholders. The bonuses awarded to our named executive officers are allocated between annual cash and long-term equity compensation. The allocation between cash and equity for our named executive officers is loosely targeted at an equal mix of each. Typically, however, we review this allocation mix each year as part of the bonus determination process so that we can take into account our annual performance results, market conditions, competitive market data, previously awarded equity and our long-term objective of retaining skilled executives. The final determination of the mix between annual cash and long-term equity is made by our Compensation Committee based on its judgment of what is in the best interest of our Company. For example, in 2008, our bonus pool was set at a level approximating target results, which in ordinary circumstances would have delivered an approximately equal mix of cash and equity awards. However, based on the economic crisis and the significant drop in stock price values occurring at that time, our Compensation Committee determined that the allocation to equity should be reduced since it would have resulted in an inflated long-term incentive opportunity disproportional to the performance results achieved due to the increased number of shares that would have been awarded as a result of the depressed value of our stock. For bonuses based on 2009 performance, our

23

Compensation Committee set an overall mix of 40% cash and 60% restricted stock. The Compensation Committee further provided that cash compensation at our most senior level positions (including certain named executive officers) could not exceed 35%, while our Chief Executive Officer and Chief Operating Officer could not exceed 30%. Our Compensation Committee felt that this mix best aligned our senior management with the immediate interests of shareholders and viewed the future upside potential of stock to be an appropriate incentive and reward to our senior positions.

Additionally, although we include employee benefits as part of our total compensation program and consider them an important element in the competitiveness of our compensation, we do not set a target for the relationship between the total value of our benefit plans relative to total compensation. We determine the level and types of benefits based on a separate review of general industry practice for broad-based employee benefits and generally strive to provide, for each jurisdiction in which we do business, a competitive level of overall benefits approximating median value in the aggregate. Currently, our employee benefits include group health insurance, dental insurance, life insurance, disability coverage, vision benefits, employee assistance plans and defined contribution retirement savings plans.

Base Salary. We use base salary to recognize the experience, skills, knowledge, roles and responsibilities of our employees and executive officers. When establishing the 2009 base salaries of our named executive officers, our Compensation Committee considered the following factors:

• competitive market data;

• the scope of the individual’s position and responsibilities;

• individual experience and qualifications;

• our ability to replace the individual based on the limited number of qualified candidates available in or willing to relocate to Bermuda (if applicable); and

• elimination of Company match contributions from our Excess Benefit Plan for participants subject to U.S. taxation, in connection with tax law changes under Section 457A of the Internal Revenue Code of 1986, as amended, and the regulations promulgated thereunder, which we refer to as the Code.

Base salaries of our named executive officers, along with other components of total compensation, are reviewed by our Compensation Committee at least annually. We expect the base salaries of our named executive officers to increase when the insurance and reinsurance market increases or when a named executive officer assumes a larger role.

In 2009, the Compensation Committee reviewed the salaries of our named executive officers in February and August. The initial evaluation in February was part of our annual compensation review cycle, from which the Compensation Committee evaluated and discussed the compensation of our leadership team, including our named executive officers, relative to our peer companies (as listed above under “Role of Peer Company Analysis”). As part of this exercise, the Compensation Committee also reviewed a recommendation from management to eliminate on a going-forward basis the annual Company paid benefits under our Excess Benefit Plan for participants that are subject to U.S. taxation, including three of our named executive officers, in connection with new tax rules established under Section 457A of the Code, and to provide a corresponding increase in salary to make these participants whole.

Based on the peer company review and management’s recommendation concerning the Excess Benefit Plan, the Compensation Committee approved salary increases for each of our named executive officers as set forth in the table below. The leading factor in determining the salary increase amount, excluding the portion attributable to the elimination of certain benefits under our Excess Benefit Plan, was the gap between current salary levels and peer company practice. Specifically, the salary levels for Messrs. Becker, Minton and Roberts were in the lowest quartile relative to peer companies as reflected in the Equilar, Inc. database. It was the Compensation Committee’s opinion that, due to the growth and increased complexity of our business model in recent years, base salary for our executives, in particular those responsible for enterprise-wide

24

functions, should be increased to levels closer to the median salary represented by the peer company analysis. Consequently, the Compensation Committee approved salary increases in February as an incremental step towards this goal, with the expectation that additional increases would be considered upon an updated review of peer market practice (and recognizing that the current review reflected market practice for 2007 since most companies had not yet filed their 2009 proxy reports outlining 2008 compensation information).

In August of 2009, we updated our peer company compensation review using updated compensation data from Equilar, Inc. that reflected 2009 proxy filings. Once again, the salary levels for Messrs. Becker, Minton and Roberts were significantly below median levels relative to peer companies as reflected in the Equilar, Inc. database. Following its review, and in keeping with its goal to close the gap incrementally between existing salary levels and peer company practice, the Compensation Committee approved additional salary increases for these three named executive officers that became effective on August 1, 2009. The table below summarizes all of the 2009 salary changes for our named executive officers:

Named Executive Officer	2009 Salary Increases						Increase Effective August 1, 2009			Salary at End of 2009			% Change from 2008
	Salary at End of 2008		Increase Effective January 1, 2009		Section 457A Increase Effective January 1, 2009

For information regarding 2010 base salary increases, please see the discussion under 2010 Compensation later in this section.

Annual Bonus and Long-Term Incentives. Subject to any guidelines provided in employment agreements, each named executive officer’s annual cash bonus and long-term incentive award is discretionary and is determined each year by our Compensation Committee taking into account the following components: Company performance, operating segment performance, individual performance and Company performance compared to peer companies.

For administrative purposes, and to simplify the method by which we link compensation levels to performance results, we treat the annual cash bonus and long-term incentive awards as a single, combined incentive opportunity. As discussed above, on an annual basis, a target “bonus” opportunity, expressed as a percentage of base salary, is established for each executive, which includes both (i) the portion that is paid in the form of a cash bonus and (ii) the portion that is paid in the form of long-term equity awards. The process by which we determine the amount of the combined award is discussed in the following narrative. In this context, the reference to “bonus” or “bonus pool” represents the combined pool available for both the annual bonus and long-term incentive awards. The process by which we determine the allocation of the pool between annual cash bonuses and long-term incentives is discussed below under Allocation Between Annual Cash and Long-Term Equity.

Company Performance Metrics and Weights: Our overall bonus pool for annual bonuses and long-term incentive awards is determined in part based on a matrix of performance measures that include absolute financial performance, performance in relation to our peer companies, and performance with respect to certain strategic objectives. In addition to these determinants, the Compensation Committee applies its business judgment taking into account the current macro-economic environment, industry-specific trends and any extraordinary events we faced during the

25

year. For 2009, the performance measures and corresponding weight assigned to each were as follows:

Performance Metric	Description	Rationale	Weight
			Absolute Measure			Relative to Peers			Overall
Operating Return on Equity (Operating ROE)	After tax operating income divided by average shareholders’ equity.	Significant barometer of our overall financial performance. It measures the return we produce on shareholder investment and the efficiency of capital deployment.		25	%		25	%		50	%
Combined Ratio	Ratio of losses and expenses against net premiums earned.	Key measure of our underwriting performance and a common benchmark for comparing performance to peer companies.		10	%		10	%		20	%
Expense Ratio	Ratio of expenses to net premiums earned.	Provides a measure of the efficiency of our operations.		5	%		5	%		10	%
Strategic Objectives	A series of corporate goals designed to increase shareholder value over time.	Measures progress towards important corporate initiatives that, over time, are intended to improve the superiority of our services, reputation and financial results.		15	%		—			15	%
Stock Price	Annual change in share price relative to a group of peer companies.	Measures the benefit to shareholders of holding our shares relative to that of peer companies.		—			5	%		5	%
Total				55	%		45	%		100	%

Absolute Performance Measures: For the absolute performance measures that are based on a financial metric (Operating ROE, Combined Ratio and Expense Ratio, as defined above), we assess performance against pre-determined objectives. For Strategic Objectives, we assess performance against pre- determined objectives in addition to performance with respect to opportunities and unplanned business initiatives that present themselves throughout the year:

• The financial metrics for Operating ROE, Combined Ratio, and Expense Ratio are measured relative to budgeted performance. We use budgeted performance expectations to create a range of potential performance outcomes that deliver corresponding levels of bonus pool funding (see table below).

Performance Level	2009 Budgeted Financial Metrics and Results
	Operating ROE			Combined Ratio			Expense Ratio
Maximum Performance(1)		22	%		81.0	%		30.5	%
Target Performance		14	%		91.0	%		31.9	%
Threshold Performance(2)		3	%		107.0	%		34.3	%
2009 Estimated Result(3)		13.5	%		90.5	%		31.3	%

(1)	Performance results above “Maximum” will not increase bonus pool funding
(2)	Performance results must be at least at “Threshold” levels to contribute funding to the bonus pool
(3)	Reflects final results used for purposes of the bonus plan. Since bonus pool decisions are made prior to the finalization of year-end results, these results include estimates. We use the most current information we have at the time bonus decisions are made to determine estimated results.

• For Strategic Objectives, we measure our progress against the goals established at the beginning of the year as well as our performance with respect to opportunities that presented

26

themselves throughout the year. We do not evaluate Strategic Objective results using any specific formula and, due to the complexity and long-term nature inherent in many of these goals, we do not assign any particular weight to any Strategic Objective. Assessing performance results for these goals is a subjective exercise conducted by the Compensation Committee. For 2009, our Strategic Objectives and results were:

2009 Strategic Objectives	2009 Progress
Increase long term shareholder wealth. We view measures of shareholder wealth to include items such as growth in book value per share and stock price. These objectives may be achieved through organic profitability, expanding our footprint either geographically or through additional platforms, merger and acquisition and capital markets activity and/or private equity infusions.	• Book value per share increased 22.1% over December 31, 2008 • Stock price increased 26.0% over December 31, 2008 • Established a new reinsurance operation in Latin America
Maintain financial strength ratings.	• Maintained our financial strength/ insurance ratings from A.M. Best Company, Moody’s, and Fitch Ratings • Received financial strength rating from Standard & Poor’s for the first time in 2009 (A- with stable outlook)
Increase brand recognition across our broker and client bases.	• Continued active branding campaign, including by way of trade press advertising, corporate hospitality events in all major operating locations, distribution of marketing materials, corporate website, corporate gift program, and participation of senior personnel in trade conferences • Continued involvement in trade articles, surveys, and editorial coverage.

Relative Performance Measures: For the relative performance measures (Operating ROE, Combined Ratio, Expense Ratio and Stock Price), we assess performance on a percentile rank basis relative to our peer companies as discussed above under “Role of Peer Company Analysis.” For each peer company and for each measure, we determine or estimate results from publicly available sources and then calculate the percentile into which our results fall. This is a formulaic exercise, with the only discretion or subjective element being the estimation of certain peer results if final results cannot be determined in time for our Compensation Committee’s review.

For 2009, our performance relative to our peers was as follows:

Performance Level	Performance Results
	Operating ROE		Combined Ratio		Expense Ratio		Stock Price
2009 Percentile Rank Among Peers(1)		50th		30th		30th		90th

⁽¹⁾ Reflects final results used for purposes of the bonus plan. Since bonus pool decisions are made prior to the finalization of year-end results, these results include estimates. We use the most current information we have at the time bonus decisions are made to determine estimated results.

Determining Final Bonus Pool Results: For each performance measure, we denominate performance results on a scale of one (1) to ten (10), with “one” representing the minimum performance level required to create threshold bonus pool funding and “ten” representing the performance required to create maximum bonus pool funding. Results below threshold are assigned

27

a score of “zero” and do not contribute to bonus pool funding. For the absolute performance measures that are based on a financial metric, we establish performance goals across this ten point scale based on the threshold, target, and maximum goals determined during the budgeting process. Strategic Objectives, on the other hand, are assigned ranking on the ten point scale based on the subjective determination of the Compensation Committee. Our 2009 absolute performance result rankings were as follows:

Performance Rank (ten point scale)	Absolute Performance Measures (total weight = 55%)
	Operating ROE Score (25% Weight)		Combined Ratio Score (10% Weight)		Expense Ratio Score (5% Weight)		Strategic Objectives Score (15% Weight)
Maximum		10		10		10		10
Target		6		6		6		6
Threshold		1		1		1		1
2009 Actual Results (55% weight)		5.5		6.5		8.5		10

For the relative performance measures, the ten-point scale correlates to our percentile rank relative to our peer group. For example, a rank of 50th percentile would result in a rating of 5.0 on this scale. Our 2009 relative performance result rankings were as follows:

Performance Rank (ten point scale)	Relative Performance Measures (total weight = 45%)
	Operating ROE Score (25% Weight)		Combined Ratio Score (10% Weight)		Expense Ratio Score (5% Weight)		Stock Price Score (5% Weight)
Maximum		10		10		10		10
Target		6		6		6		6
Threshold		1		1		1		1
2009 Actual Results (45% weight)		5		3		3		9

The final performance result on the ten-point scale is simply the weighted average of the absolute and relative performance component results. For 2009, our total score on the ten-point scale was 6.1. Our incentive pool for annual bonuses and long-term incentive awards is determined through the aggregation of target bonuses for all of the employees eligible to receive an incentive award, including our named executive officers, multiplied by the performance result percentage of target. Target incentive bonus, which includes both the annual and long-term incentive award opportunity, is reflected as a percentage of base salary and can range from 10 to 300% of base salary. The aggregation of these amounts establishes an initial bonus pool. At this juncture, our Compensation Committee employs its business judgment taking into account both positive and negative extraordinary items as well as its evaluation of competitive pressures we are facing. Based on this process, the final bonus pool for 2009 was $48 million, with $19.2 million allocated for cash bonuses and $28.8 million allocated for shares of restricted stock valued based on the closing share price on the grant date of March 1, 2010, approximately a mix of 40% cash and 60% restricted stock.

Allocation of Bonus Pool to Operating Segments and Corporate: After the overall bonus pool has been determined, it is allocated amongst our operating segments based on their contribution to our overall results, creating sub-pools for our operating segments and corporate departments. The process of allocating the pool to the operating segments and to corporate departments is a subjective exercise conducted by our Chief Executive Officer and certain members of his leadership team. Factors considered for determining sub pools primarily relate to the assessment of the relative contributions of each operating segment and to our overall results.

For 2009, we began the process of allocating the available pool for bonuses to our segments (including operating segments and the corporate department) by assessing the aggregate amount of employee budgeted target bonuses in each segment. Management then considered objective and subjective factors in determining whether the initial amount for each segment should be adjusted. Objective factors considered for operating segments included combined ratio, expense ratio and return on utilized capital, while factors for the corporate department were inherently more subjective

28

in that they were based on the department’s contribution to overall company objectives such as increasing long term shareholder wealth, maintenance of financial strength ratings and increasing brand recognition. No specific formula was established for measuring the performance of any of the above factors and no factor was assigned any particular weight. The level of achievement in 2009 with respect to each of the objectives for each segment, considering both the objective and subjective factors, was found to be generally in line with expectations. Due to the similarity of actual performance verses expected performance among the segments, there were only minor adjustments to the initial allocations. These minor adjustments related to management’s subjective considerations rather than to any measurable or formulaic relationship between the relative performances of the segments, for example, the relative competitiveness of the markets in which the segments operate. Within each segment, the bonus pool is then allocated to departments and individuals pursuant to the judgment of segment managers.

The allocation of the bonus pool to segments did not directly impact the specific bonuses awarded to our named executive officers since their bonus awards (other than for our Chief Executive Officer) are set separately and beforehand by our Chief Executive Officer in consultation with our Compensation Committee. The bonus awarded to our Chief Executive Officer is set directly by our Compensation Committee. The manner in which bonuses to the named executive officers are set is discussed below under “Individual Performance Assessment.”

Individual Performance Assessment: Individual awards for our named executive officers are determined based on departmental and/or individual performance results. For our Chief Executive Officer, this assessment is made by the Compensation Committee, and for our other named executive officers, this assessment is made by our Chief Executive Officer and presented to the Compensation Committee for approval. This is a subjective process taking into consideration measurable financial results, amongst other factors.

Individual performance assessments of our named executive officers include but are not limited to identifying and rewarding those personal qualities and characteristics relevant to the individual’s job performance and key corporate goals, including (i) personal contribution to short-term and long-term business results, (ii) successful execution of key Strategic Objectives, (iii) demonstrated leadership capability, (iv) demonstrated application of relevant technical expertise, (v) ethical conduct and (vi) regulatory compliance. These factors, while considered in their totality by our Compensation Committee, are not assigned a particular weight during the evaluation process. Our Compensation Committee meets regularly with management to review the progress and individual contributions of our named executive officers towards these goals and objectives. Final performance evaluations are determined by the Compensation Committee after consideration of the performance assessments and recommendations made by our Chief Executive Officer with respect to the other named executive officers.

For our named executive officers, the following individual performance results were considered by the Compensation Committee in connection with the determination of 2009 bonus payments:

Named Executive Officer	Individual Performance Factors Considered for Determining Final Bonus Amount
W. Marston Becker	•	Operating company leadership and success on several key financial objectives, including achievement of:
		™	Operating ROE of 14.7% vs. 14.2% plan
		™	Combined Ratio of 88.1% vs. a 91.2% plan
		™	Expense Ratio of 30.1% vs. 31.9% plan
	•	Leadership in identifying strategic initiatives and individual contributions on strategic progress
Joseph W. Roberts	•	Leadership in creating sound financial discipline across our jurisdictions to ensure adherence to regulatory reporting requirements, including fully compliant Sarbanes-Oxley controls
	•	Played a key role in the assessment of corporate strategic initiatives

29

Named Executive Officer	Individual Performance Factors Considered for Determining Final Bonus Amount
	•	Considerable efforts in investor relations through personal visits and communications with investors
	•	Obtained the Company’s first Standard & Poor’s financial strength rating
Peter A. Minton	•	Execution of technical expertise in our pricing and reserving discipline
	•	Cost containment achieved based on realignment of investment services
	•	Progress on key information technology initiatives against three year plan
	•	Successful search and selection of several key function heads
Angelo M. Guagliano	•	Successful execution of strong underwriting discipline and resulting profitability in excess of plan goals
	•	Leadership and on-going guidance of underwriting and claims practice groups
Adam C. Mullan	•	Exceeded planned profitability of Alterra at Lloyd’s
	•	Successful build-out of the Alterra at Lloyd’s underwriting platforms
	•	Leadership in expanding our business into Latin America

Final Allocation of Bonuses to Named Executive Officers: Based on our 2009 performance and the assessment of individual contributions towards such performance, the 2009 bonus payments for our named executive officers, including both the annual cash and long-term equity portions, were as follows:

2009 Bonuses for Named Executive Officers (includes both annual cash and long-term equity components)
Named Executive Officer	Target Bonus					Final Bonus
	% of Salary			$ Amount		% of Salary			$ Amount
W. Marston Becker		300	%		3,197,400		319	%		3,400,000
Joseph W. Roberts		250	%		1,125,000		250	%		1,125,000
Peter A. Minton		250	%		1,670,750		284	%		1,900,000
Angelo M. Guagliano		250	%		1,377,000		261	%		1,440,000
Adam C. Mullan		250	%		1,231,275		184	%		905,000

Allocation Between Annual Cash and Long-Term Equity: In determining the mix of cash and restricted stock for each of the named executive officers, our Compensation Committee considered: the Company’s performance versus the targeted performance expectations, the individual’s contribution to Company performance, as well as the named executive officer’s total compensation relative to the compensation paid to similarly situated executives at peer companies. Generally, restricted stock is subject to three-year cliff vesting because our Compensation Committee believes this period to be an effective performance and retention tool since the named executive officers are in a position to influence longer term results and the restricted stock is generally forfeited if the named executive officer terminates employment.

2009 Allocation Between Cash and Long-Term Equity
Named Executive Officer	Final Bonus
	Cash Bonus Portion			Restricted Stock Portion			Total $		% of Salary
W. Marston Becker		30	%		70	%		3,400,000		319	%
Joseph W. Roberts		35	%		65	%		1,125,000		250	%
Peter A. Minton		30	%		70	%		1,900,000		284	%
Angelo M. Guagliano		35	%		65	%		1,440,000		261	%
Adam C. Mullan		35	%		65	%		905,000		184	%

30

The cash portion of the 2009 bonus payment was paid prior to March 15, 2010. The restricted stock portion of the 2009 bonus payment was converted into restricted stock by dividing the applicable dollar amounts by the closing price of our stock on the March 1, 2010 grant date. These awards vest on the third anniversary of the grant date if the named executive officer is employed on the vesting date or if the named executive officer retires (as defined in the award agreement). The named executive officer will be entitled to accelerated vesting in the event of the named executive officer’s death, disability, termination without Cause or termination for Good Reason from the Company (as these terms are defined under “Employment Agreements” below or as defined in the award agreements) or upon a change in control (as defined in the description of our 2008 Incentive Plan) provided such change in control does not occur within 12 months from the award date, or the failure of the Bermuda immigration authorities to renew a Bermuda-based named executive officer’s work permit (through no fault of the employee). Should an employee voluntarily terminate his or her employment, all unvested shares are forfeited.

Perquisites

We provide certain perquisites to our executives to aid in attracting and retaining executive talent. Most of these benefits are intended to address issues and incremental expenses for those executives that have relocated to Bermuda from another country that would not have otherwise been incurred if relocation to Bermuda were not required. These benefits include:

Perquisite	Purpose/Description
Housing Allowance	Due to limitations on property ownership in Bermuda and due to the significant cost of rentals, we provide a housing allowance up to $15,000 per month in the case of our Chief Executive Officer and up to $10,000 per month for other executives that have relocated to Bermuda.
TIPRAA Gross-Ups	To mitigate the additional personal income taxes that are due on the housing allowance, we provide a payment to our executives that have relocated to Bermuda in an amount equal to the additional taxes incurred as a result of the housing allowance and corresponding tax gross-up.
Automobile Allowance	This is a common benefit provided by our peers in Bermuda and consequently we offer a similar benefit in order to keep our compensation packages competitive. We provide an allowance of up to $60,000 in the case of our Chief Executive Officer and $40,000 for other executives every five years for the purchase of an automobile.
Reimbursement for Financial and Tax Preparation Fees	To mitigate the additional expense of managing complex tax issues and form preparation related to having expatriate status, we provide for the reimbursement of these fees up to $13,000 per year to our executives that have relocated to Bermuda.
Home Travel Allowance	To mitigate the increased travel expense incurred by relocating to Bermuda from the executive’s home country, we provide our expatriates with a personal travel allowance of up to $25,000 per year in the case of our Chief Executive Officer and up to $20,000 per year for other executives that have relocated to Bermuda.
Reimbursement for Country Club Dues	To facilitate networking with clients and other business executives, we provide for reimbursement of club membership fees up to $12,000 per year in the case of our Chief Executive Officer and up to $8,000 per year for other executives.

31

While we intend to maintain these perquisite programs for our named executive officers, our Compensation Committee may revise, amend, or add to these benefit programs at its discretion, subject to any applicable provisions in the named executive officer’s employment agreement.

Other Equity Awards

We grant stock option awards principally in cases where our new employees leave behind stock options or other awards at their former employers and seek to be compensated by us. After commencement of the employment relationship and going forward, our Compensation Committee anticipates an expanded use of restricted stock and restricted stock unit awards as opposed to stock options. This shift is due in a large part to the accounting treatment for stock options under the Financial Accounting Standards Board (FASB) Accounting Standards Codification (ASC) Topic 718, Stock Compensation (formerly, FASB Statement 123R), which has made granting stock options less attractive to us. Furthermore, our Compensation Committee believes that restricted stock provides an equally motivating form of incentive compensation while serving to better align the interests of our shareholders and management.

We also selectively grant ad hoc restricted stock and performance equity awards in instances where the Compensation Committee feels we need to mitigate retention exposure or to focus additional attention on achievement of special projects or business initiatives. In 2009, to provide further incentive to Mr. Becker to focus on increasing shareholder value, our Compensation Committee awarded a performance-based equity award of 108,333 stock options and 33,333 shares of restricted stock with vesting restrictions that will lapse only to the extent that the performance measures are met over a two-year period. For each of these awards, 50% would vest on January 1, 2010 if our book value per share on December 31, 2009 has increased by at least 12.5% from our book value per share on December 31, 2008, and any remaining unvested shares will vest on January 1, 2011 if our book value per share on December 31, 2010 has increased by at least 25% from our book value per share on December 31, 2008. The Compensation Committee chose to use increase-in-book value as the performance criterion since it views book value as an important measure for assessing our success in creating shareholder wealth. The award level was set equal to the number of performance-based stock options and restricted stock that Mr. Becker forfeited in 2008 as a result of the book value performance targets not being achieved. It was the Compensation Committee’s opinion that the performance metrics for those awards would have been achieved had the credit crisis not occurred at the time it did. As a result, the Compensation Committee felt that it was in our best long-term interests to make these additional performance-based awards to Mr. Becker. On February 8, 2010, after certification by our Compensation Committee as to the achievement of the applicable performance measures, 16,667 of these restricted common shares and 54,167 of these options vested.

Employment Agreements

Our general policy is to enter into employment agreements with our named executive officers and certain other select executives with significant underwriting and/or policy making responsibilities in order to set forth the terms of their employment and to provide certain protections to both parties in the event of termination of employment or a change in control. We currently have agreements with Messrs. Becker, Roberts, Minton, and Guagliano, each of whom has been a named executive officer for at least the last four years. We anticipate entering into an employment agreement with Mr. Mullan in 2010 on substantially the same terms as other similarly situated executives. Although the employment agreements provide a framework for the aggregate compensation paid to each named executive officer, the employment agreements do not prescribe a specified mix of short-term and long-term compensation for our named executive officers. Instead, our Compensation Committee has broad discretion to determine the appropriate compensation mix with respect to each named executive officer.

In recognition of Mr. Becker’s lead position with us and as an incentive for him to join us in late 2006, our Compensation Committee agreed during the negotiation process to expressly set a

32

target bonus for Mr. Becker within his employment agreement. The employment agreement for Mr. Becker specifies a target cash bonus at 100% of base salary with a range from 0% to 250%. The employment agreements for Messrs. Roberts, Minton and Guagliano provide that, at the beginning of each calendar year, or shortly thereafter, our board of directors or its designated committee will provide a target bonus amount for such year to the executive. Pursuant to each of their employment agreements, a target bonus below 50% of base salary would constitute Good Reason (as defined under “Employment Agreements” below) triggering severance payments by us to the executive officer if the executive elects to terminate his employment. The target cash bonus in 2009 for each of Messrs. Roberts, Minton and Guagliano was 87.5% of base salary.

For information regarding 2010 base salary increases, please see the discussion under 2010 Compensation later in this section.

Change in Control and Severance

Upon termination of employment or a change in control, our named executive officers may receive (i) accelerated vesting of awards granted under our equity plans and/or (ii) severance payments under the circumstances described below.

Generally under our equity plans and award agreements, if a change in control occurs, (i) the then outstanding options become immediately exercisable, (ii) the restricted period on restricted stock awards and restricted stock units expires (including a waiver of any applicable performance goals), (iii) the performance periods in effect end and our Compensation Committee will (x) determine the extent to which performance goals have been met and (y) cause the named executive officer to receive partial or full payment of awards and (iv) any awards previously deferred will be settled in full as soon as practicable. For more details on these provisions, please see “Potential Payments upon Termination or Change in Control.”

Upon termination of employment, our named executive officers are eligible to receive severance payments which, depending upon the circumstances surrounding termination and the terms of the applicable employment agreement, may include:

• a cash payment based on a multiple of the named executive officer’s base salary set forth in his employment agreement or actual base salary at the time of termination;

• a pro-rated target bonus for the year of termination (as determined in good faith by our Compensation Committee based on the relative achievement of performance targets through the termination date);

• in the case of Messrs. Becker, Minton, Roberts and Guagliano, a cash payment reflecting a multiple of the named executive officer’s last paid bonus; and

• accelerated vesting of equity awards.

In addition, Mr. Roberts’ employment agreement provides vesting credit with respect to 35,000 of the 48,699 shares comprising his February 2007 award in the event his termination arises without Cause or for Good Reason (as defined below). Our Compensation Committee elected to include this language in Mr. Roberts’ employment agreement in recognition of his then new role with us and its attendant responsibilities.

Our severance obligations are designed to be competitive with the amounts payable to executives in similar positions at similar companies. Termination payments to a named executive officer with an employment agreement are made within the time period specified in the respective employment agreement and are contingent upon the named executive officer’s continued compliance with certain restrictive covenants and the execution of a release of claims.

The change in control provisions reflect our belief that our named executive officers and other employees who have built our Company into a successful enterprise should be protected in the event of a change in control. Further, we believe the interests of shareholders will be best served if the interests of our named executive officers are aligned with shareholders, and providing change in control benefits should eliminate, or at least reduce, any potential reluctance of our named executive

33

officers to pursue potential change in control transactions that may be in the best interests of shareholders.

While the definition of “change in control” (discussed below under “Payments upon Termination or Change in Control”) contained in the employment agreements of Messrs. Becker, Roberts and Minton and Mr. Guagliano are materially similar, the definition in Mr. Guagliano’s agreement reflects employment by Alterra Insurance. As such, while there is substantial overlap among the definitions, Mr. Guagliano’s definition contains references to Alterra Insurance for purposes of describing occurrences that would constitute a change in control under his agreement.

The definitions of “Good Reason” (discussed below under “Payments upon Termination or Change in Control”) in the employment agreements of Mr. Becker and Messrs. Roberts, Minton and Guagliano contain a small degree of variation. Mr. Becker’s employment agreement was negotiated prior to those of Messrs. Roberts, Minton and Guagliano and reflects his role as Chief Executive Officer. These variations are a result of those negotiations and Mr. Becker’s position.

In addition to accelerated vesting of equity awards upon (i) death, (ii) disability, (iii) termination without Cause and (iv) termination for Good Reason, our Bermuda-based named executive officers may receive accelerated vesting of restricted stock upon the failure of the Bermuda immigration authorities to renew a Bermuda-based named executive officer’s work permit (through no fault of the employee) and we do not offer a comparable position at an affiliate. We believe accelerated vesting under these circumstances is appropriate because we recognize that failure to renew a Bermuda work permit for our Bermuda-based named executive officers could serve as a constructive termination.

Section 162(m) Disclosure

Code Section 162(m) limits the tax deductibility by U.S. companies of certain compensation paid to “covered employees” within the meaning of Code Section 162(m). This provision generally disallows a tax deduction to public corporations for compensation in excess of $1,000,000 per year unless it is considered performance-based compensation under the Code. None of the 2009 named executive officers were employees of a U.S. subsidiary.

In those cases where Code Section 162(m) is applicable, we believe that the corporate income tax deductibility of compensation is an important factor, but not the sole factor, in setting executive compensation policy or in rewarding executive performance. Accordingly, although we generally intend to avoid the loss of a tax deduction due to Code Section 162(m), we reserve the right to pay amounts that are not deductible in appropriate circumstances.

2010 Compensation

In 2010, in connection with our annual compensation review and in order to align base salary with competitive market levels, base salary increases were approved for Messrs. Roberts, Minton and Guagliano in the amount of $50,000, $50,000,and $25,000, respectively, resulting in new salaries of $500,000, $718,300,and $575,800, respectively, effective January 1, 2010. The salaries for Messrs. Becker and Mullan were also reviewed relative to competitive market practice but were not changed.

Also, the 2010 annual cash bonus targets for Messrs. Becker, Roberts, Minton and Guagliano have been set to 100%, 87.5%, 87.5% and 87.5%, respectively, remaining at the 2009 level. Mr. Mullan’s 2010 annual cash bonus target will be set in conjunction with the finalization of his employment agreement.

On March 3, 2010, Alterra Capital announced entry into an amalgamation agreement with Alterra Holdings Limited, its wholly owned subsidiary and Harbor Point Limited, pursuant to which Harbor Point Limited amalgamated with Alterra Holdings Limited. The amalgamation closed on May 12, 2010. Equity Awards for Messrs. Becker, Roberts, Minton, Guagliano and Mullan evidencing stock options, restricted shares or restricted share units (with the exception of those equity awards granted after December 31, 2009) would have vested upon the consummation of the

34

amalgamation. Notwithstanding this right to accelerated vesting, as a result of negotiations related to the amalgamation, and to ensure continued alignment with shareholders and to focus attention on the successful integration of the combined company, each of Messrs Becker, Roberts, Minton, Guagliano and Mullan agreed to waive 100% of the accelerated vesting of these equity awards, which we refer to as the affected awards. Therefore, the affected awards did not vest in connection with the amalgamation and will remain subject to their original vesting requirements, except all affected awards will become fully vested upon the applicable named executive officer’s death or termination of employment without “Cause” or due to “Disability,” or by the named executive officer for “Good Reason” (as those terms are defined in the applicable named executive officer’s employment agreement or in the Incentive Plan). In the event of the named executive officer’s Retirement (as defined in the applicable Incentive Plan or the award agreement), the affected awards will continue to vest in accordance with their current terms.

Following the closing of the amalgamation, our Compensation Committee established a pool for retention awards with an aggregate grant date fair value of $10.1 million to be made to certain key Alterra Capital executive officers. A portion of the pool ($4.8 million) was allocated for awards to executives who were employed by Max Capital (or its affiliates) prior to the amalgamation and a portion of the pool ($5.3 million) was allocated for awards to executives who were previously employed by Harbor Point Limited. Subject to their continued employment on the grant date, which is expected to be June 29, 2010, each of Messrs. Becker, Roberts, Minton and Mullan will receive a retention award in the form of restricted stock or restricted stock units from this pool.

The retention awards will be subject to both time-based and performance-based vesting conditions and will vest on August 15, 2015 subject to both the attainment of ten (10) percent per year compound annual growth in tangible book value per share (inclusive of paid dividends) from June 30, 2010 and the executive’s continued service on the vesting date. If the executive’s service is terminated prior to the vesting date, the award will automatically be forfeited, except that, in the case of the executive’s death or disability or, under certain circumstances, termination of the executive’s employment because we are unable obtain a work permit for the executive, the award will fully vest and in the case of the executive’s termination without cause or for good reason, the award will continue to vest as if the executive remained in service, subject to the achievement of performance results. In the case of the executive’s retirement, so long as the executive has been in service with us for at least 24 months following the grant date and he does not enter into an employment or service agreement that has not been preapproved by us prior to the vesting date, vesting will continue as if the executive remained in service, subject to the achievement of performance results. Our Compensation Committee has the discretion to accelerate the vesting of these retention awards in the event of a change in control (as defined in the 2008 Incentive Plan).

The table below shows the dollar value at grant date to be received by each of our named executive officers under this retention pool. Mr. Guagliano resigned from our Company effective May 31, 2010 and did not receive a retention award.

Named Executive Officer	Award Dollar Value at Grant Date
W. Marston Becker		$	1,700,000
Joseph W. Roberts		$	600,000
Peter A. Minton		$	800,000
Adam C. Mullan		$	500,000

The number of restricted shares to be issued from the pool will be based on the average price per common share for the 20 trading days commencing on May 28, 2010, which was the ex-dividend date for the Company’s special dividend declared on May 20, 2010.

Employment Agreements

The following paragraphs summarize the employment agreements of our named executive officers. The employment agreements also provide for severance upon certain terminations of employment. The severance provisions are described below in the section titled “Potential Payments Upon Termination or Change in Control.”

W. Marston Becker. On December 8, 2006, we entered into an employment agreement with Mr. Becker under which he serves as our Chairman and Chief Executive Officer for a term that began on November 13, 2006 and ends on November 13, 2011. Mr. Becker’s employment agreement was revised in December 2008 to comply with Code Section 409A. The agreement provides for an annual base salary of $750,000, subject to increase at the discretion of our Compensation Committee, and an annual bonus targeted at 100% of base salary with a range of 0% to 250% of base salary. The employment agreement also provided for an initial award of 100,000 restricted shares and 325,000 stock options, each divided into three equal tranches. The first tranche vested on January 1, 2007. The second tranche vested on January 1, 2008 upon the successful attainment of performance goals specified in Mr. Becker’s employment agreement as certified by our Compensation Committee on February 11, 2008. The remaining tranche was forfeited on December 31, 2008 due to performance criteria not being met.

Under the terms of his employment agreement, Mr. Becker also receives an automobile allowance of $1,000 per month, payment of country club dues not to exceed $1,000 per month, a housing allowance not to exceed $15,000 per month (plus a gross-up to the extent and in the manner we provide to our other senior executive officers who are subject to U.S. income tax) or, if more favorable to Mr. Becker, in the aggregate, the amount otherwise provided to our other senior executive officers, and participation in pension, life insurance, health, disability and major medical insurance plans, and in such other employee benefit plans that may be established during the term of his employment. Mr. Becker is also entitled to six weeks of paid vacation each year and access to a private plane as needed in accordance with company policy.

Mr. Becker is subject to one-year post-termination non-competition and non-solicitation restrictions in addition to perpetual confidentiality and non-disparagement requirements.

For 2009, Mr. Becker was paid a base salary of $978,300 and was awarded a cash bonus in the amount of $1,020,000. For 2010, Mr. Becker’s base salary is set at $1,065,800, the same base salary in effect at the end of 2009. This base salary amount for Mr. Becker includes a salary adjustment initially applied in 2009 in the amount of $65,800, which accounts for Mr. Becker’s loss of benefits under our Excess Benefit Plan.

Joseph W. Roberts. Effective April 1, 2007, we entered into an employment agreement with Mr. Roberts pursuant to which Mr. Roberts serves as our Executive Vice President and Chief Financial Officer. Mr. Roberts’ employment agreement runs for three years with automatic one-year extensions subject to six-month non-renewal notice by either Mr. Roberts or us. The agreement provides for an annual base salary of not less than $325,000 subject to increase at the discretion of our Compensation Committee. Pursuant to the terms of his employment agreement, Mr. Roberts is eligible for an annual bonus determined in accordance with the bonus policy applicable to our senior executive officers located in Bermuda. For 2009, Mr. Roberts’ annual bonus was targeted at 87.5% of base salary and this target has not changed for 2010.

Under the terms of his employment agreement, Mr. Roberts is also entitled to perquisites commensurate with those provided to other executive vice presidents in Bermuda, including (i) a housing allowance of not less than $10,000 per month, (ii) a club dues allowance, (iii) an automobile allowance, (iv) a travel allowance, (v) tax and financial planning services and (vi) a tax gross-up. Mr. Roberts is entitled to participate in our pension, life insurance, health, disability and major medical insurance plans, and in such other employee benefit plans that may be established during the term of his employment. Mr. Roberts is also entitled to no less than four weeks of paid vacation each year.

Mr. Roberts is subject to one-year post-termination non-competition and non-solicitation restrictions in addition to perpetual confidentiality and non-disparagement requirements.

42

For 2009, Mr. Roberts was paid a base salary of $415,000 and was awarded a cash bonus in the amount of $393,750. For 2010, Mr. Roberts’ base salary was increased to $500,000, representing a $50,000 increase in the base salary in effect for Mr. Roberts at the end of 2009.

Peter A. Minton. Effective April 1, 2007, we entered into an employment agreement with Mr. Minton pursuant to which Mr. Minton serves as our Executive Vice President and Chief Operating Officer. Mr. Minton’s employment agreement runs for three years with automatic one-year extensions subject to six-month non-renewal notice by either Mr. Minton or us. Mr. Minton’s employment agreement was revised in December 2008 to comply with Code Section 409A. The agreement provides for an annual base salary of not less than $500,000 subject to increase at the discretion of our Compensation Committee. Pursuant to the terms of the employment agreement, Mr. Minton is eligible for an annual bonus determined in accordance with the bonus policy applicable to our senior executive officers located in Bermuda. For 2009, Mr. Minton’s annual bonus was targeted at 87.5% of base salary and this target has not changed for 2010.

Under the terms of his employment agreement, Mr. Minton is also entitled to perquisites commensurate with those provided to other executive vice presidents in Bermuda, including (i) a housing allowance of not less than $10,000 per month, (ii) a club dues allowance, (iii) an automobile allowance, (iv) a travel allowance, (v) tax and financial planning services and (vi) a tax gross-up. Mr. Minton is entitled to participate in our pension, life insurance, health, disability and major medical insurance plans, and in such other employee benefit plans that may be established during the term of his employment. Mr. Minton is also entitled to no less than four weeks of paid vacation each year.

Mr. Minton is subject to one-year post-termination non-competition and non-solicitation restrictions in addition to perpetual confidentiality and non-disparagement requirements.

For 2009, Mr. Minton was paid a base salary of $624,550 and was awarded a cash bonus in the amount of $570,000. For 2010, Mr. Minton’s base salary was increased to $718,300 representing a $50,000 increase in the base salary in effect for Mr. Minton at the end of 2009. This base salary amount for Mr. Minton includes a recurring salary adjustment initially applied in 2009 in the amount of $43,300, which accounts for Mr. Minton’s loss of benefits under our Excess Benefit Plan.

Angelo M. Guagliano. Effective April 1, 2007, Alterra Insurance entered into an employment agreement with Mr. Guagliano, pursuant to which Mr. Guagliano serves as President and Chief Executive Officer of Alterra Insurance. Mr. Guagliano’s employment agreement runs for three years with automatic one-year extensions subject to six-month non-renewal notice by either Mr. Guagliano or Alterra Insurance. Mr. Guagliano’s employment agreement was revised in December 2008 to comply with Code Section 409A. The agreement provides for an annual base salary of not less than $475,000 subject to increase at the discretion of our Compensation Committee. Pursuant to the terms of the employment agreement, Mr. Guagliano is eligible for an annual bonus determined in accordance with the bonus policy applicable to other senior executive officers located in Bermuda. For 2009, Mr. Guagliano’s annual bonus was targeted at 87.5% of base salary and this target has not changed for 2010.

Under the terms of his employment agreement, Mr. Guagliano is also entitled to receive perquisites commensurate with those provided to other executive vice presidents in Bermuda, including (i) a housing allowance of not less than $10,000 per month, (ii) a club dues allowance, (iii) an automobile allowance, (iv) a travel allowance, (v) tax and financial planning services and (vi) a tax gross-up. Mr. Guagliano is entitled to participate in our pension, life insurance, health, disability and major medical insurance plans, and in such other employee benefit plans that may be established during the term of his employment. Mr. Guagliano is also entitled to no less than four weeks of paid vacation each year.

Mr. Guagliano is subject to one-year post-termination non-competition and non-solicitation restrictions in addition to perpetual confidentiality and non-disparagement requirements.

For 2009, Mr. Guagliano was paid a base salary of $550,800 and was awarded a cash bonus in the amount of $504,000. For 2010, Mr. Guagliano’s base salary was increased to $575,800, representing a $25,000 increase in the base salary in effect for Mr. Guagliano at the end of 2009.

43

This base salary amount for Mr. Guagliano includes a salary adjustment initially applied in 2009 in the amount of $40,800, which accounts for Mr. Guagliano’s loss of benefits under our Excess Benefit Plan.

Adam C. Mullan. In 2005, we entered into an employment offer letter with Mr. Mullan pursuant to which he served as a Managing Director of Alterra Reinsurance Europe Limited. The offer letter provided for an annual base salary of £150,000 subject to annual review and provided for Mr. Mullan’s participation in our annual cash bonus program and long-term incentive plan. Mr. Mullan also participated in a contributory pension scheme pursuant to which he contributed 5% of his base salary and his employer contributed an amount equal to 10% of his base salary. Mr. Mullan was also entitled to a car allowance of €1,500 per month, club initiation fees up to €10,000 and annual club dues of €3,000, annual financial planning expenses of €8,000 and payment of an annual physical examination. Mr. Mullan was also entitled to participate in certain employee benefit schemes, including a short-term disability scheme, long-term disability scheme and health, life and dental schemes. In November 2009, Mr. Mullan was appointed Chief Executive Officer of Alterra at Lloyd’s and we are presently negotiating a new employment agreement with him, the terms and conditions of which will be based on those of similarly situated executives.

For 2009, Mr. Mullan was paid a base salary of $396,197 and was awarded a cash bonus in the amount of $316,750. For 2010, Mr. Mullan’s base salary is set at $492,510, the same base salary in effect at the end of 2009. In connection with Mr. Mullan’s promotion to Chief Executive Officer of Alterra at Lloyd’s, the portion of his compensation paid after October 2009 was paid, and will continue to be paid, in pounds sterling (GBP); this portion of his compensation has been converted to U.S. dollars using the spot rate in effect at the time the payments were made.

2008 Incentive Plan

General. The purpose of our 2008 Incentive Plan, which was approved at our May 2008 Annual General Meeting, is to allow us to attract and retain key personnel and provide a means whereby our directors, officers, employees, consultants and advisors can acquire and maintain an equity interest in us, or be paid incentive compensation, which may (but need not) be measured by reference to the value of our shares, thereby strengthening their commitment to our welfare and aligning their interests with those of our shareholders. Our 2008 Incentive Plan has a term of ten years and no further awards may be granted under the 2008 Incentive Plan after that date.

Administration. Our Compensation Committee administers our 2008 Incentive Plan and has the authority to determine the terms and conditions of any agreements evidencing any awards granted under our 2008 Incentive Plan and to adopt, alter and repeal rules, guidelines and practices relating to our 2008 Incentive Plan.

Awards Available for Grant. Our Compensation Committee may grant awards of non-qualified stock options, incentive (qualified) stock options, stock appreciation rights, restricted stock awards, restricted stock units, stock bonus awards, performance compensation awards (including cash bonus awards) or any combination of the foregoing.

Number of Shares Authorized. Our 2008 Incentive Plan provides for an aggregate of 4,500,000 common shares to be available for awards. No participant may be granted awards of options or stock appreciation rights with respect to more than 600,000 common shares in any one year. No more than 600,000 common shares (or the equivalent fair market value thereof) may be earned in respect of performance compensation awards granted to any participant for a single calendar year during a performance period. The maximum amount that can be paid to a participant in any calendar year pursuant to a performance compensation award in the form of a cash bonus is $15,000,000. If there is a change in our corporate capitalization or a corporate transaction or event that affects our common shares, our Compensation Committee in its sole discretion may make substitutions or adjustments to the number of shares reserved for issuance, the number of shares covered by awards then outstanding, the limitations on awards, the exercise price of outstanding options and such other equitable substitution or adjustments as it may determine appropriate under our 2008 Incentive Plan.

44

Transferability. In general, awards granted under our 2008 Incentive Plan may only be exercised by the participant, subject to certain permissible transfers by will or laws of descent or in the discretion of our Compensation Committee.

Amendment. Our board of directors may amend, suspend or terminate our 2008 Incentive Plan at any time, subject to any shareholder approval requirements related to the amendment of our 2008 Incentive Plan. No amendment, suspension or termination will impair the rights of any participant or recipient of any award without the consent of the participant or recipient.

Change in Control. In the event of a “change in control” (as defined below), our Compensation Committee may provide that all or any portion of any outstanding options and equity awards (other than performance compensation awards) issued under our 2008 Incentive Plan will become fully vested and performance compensation awards will vest based on the level of attainment of the specified performance goals or assuming that target levels of performance have been attained, or on some other basis, as determined by our Compensation Committee. Our Compensation Committee may, in its discretion, cancel outstanding awards and pay the value of such awards to the participants in connection with a change in control.

For purposes of our 2008 Incentive Plan, “change in control” means (i) a sale, lease exchange or other transfer (in one or more related transactions) of all or substantially all of our assets or those of Alterra Insurance, (ii) any person or group of persons becomes the beneficial owner of our outstanding securities that represent 51% or more of the combined voting power of our then outstanding securities, provided, that, certain types of acquisitions (e.g., certain acquisitions directly from us or by us or by an employee benefit plan that we sponsor) will not constitute a change in control, (iii) during any period of two consecutive years, individuals who at the beginning of that period constituted our board of directors (together with any new directors subsequently elected to our board of directors whose nomination by our shareholders was approved by a vote of our board of directors then still in office who are either directors at the beginning of that period or whose election or nomination for election was so previously approved) cease for any reason to constitute a majority of our board of directors then in office, (iv) our board of directors or shareholders approve a merger or consolidation of us with any other corporation, other than a merger or consolidation that would result in our voting securities outstanding immediately prior thereto continuing to represent at least 50% of the total voting power represented by our voting securities immediately after the merger or consolidation and at least a majority of the members of our board or directors of the resultant entity after the transaction were members of our board of directors at the time of the execution of the initial agreement or of the action of our board of directors providing for the transaction, or (v) our board of directors or shareholders approve a plan of complete liquidation of us or an agreement for the sale or disposition by us (in one or a series of transactions) of all or substantially all of our assets.

The closing of the amalgamation constituted a change in control under our 2008 Incentive Plan triggering accelerated vesting of unvested equity awards (other than equity awards granted after December 31, 2009). As discussed in the Compensation Discussion and Analysis, our named executive officers agreed to waive the accelerated vesting of their equity awards in connection with the amalgamation. Notwithstanding this waiver, Mr. Guagliano resigned from the Company effective May 31, 2010 pursuant to Section 6(d) of his employment agreement. As a result, all of Mr. Guagliano’s affected awards vested on that date.

Nonqualified Deferred Compensation Plans

We maintain three nonqualified deferred compensation plans in which certain named executive officers of Alterra Capital who are U.S. taxpayers participate: the Excess Benefit Plan, the Top Hat Plan and the Deferred Compensation Plan for U.S. Citizens.

The Excess Benefit Plan was established on January 1, 2005 to enable salaried employees who participate in the Alterra Capital Holdings Limited 401(k) Plan to receive employer contributions that are in excess of the limits imposed on contributions to the 401(k) Plan under Code Section 415, or, effective as of January 1, 2008, under Code Section 401(a)(17). Each year, we make a

45

contribution to the Excess Benefit Plan on behalf of each participant in an amount equal to the difference between (i) the amount we would have contributed to the 401(k) Plan if the limitations imposed under Code Section 415 (for years prior to 2008) or 401(a)(17) (for 2008) did not apply and (ii) the amount we actually contributed to the 401(k) Plan for the participant. Participants are not permitted to make contributions to the Excess Benefit Plan. On December 31, 2008, participants who were not yet 100% vested became immediately vested and the Excess Benefit Plan was frozen following the enactment of Code Section 457A. No further contributions may be made to the Excess Benefit Plan.

The Top Hat Plan, which was established on January 1, 2005, permits a select group of our management employees to elect to defer receipt of all or any portion of their annual base salaries and/or annual cash bonuses in accordance with the requirements imposed by Code Section 409A. The Top Hat Plan is the successor plan to the Deferred Compensation Plan for U.S. Citizens, which plan is substantially identical to the Top Hat Plan (except for the vesting requirements discussed below) but does not permit salary and bonus deferrals for periods after December 31, 2005. Effective December 31, 2008, the Top Hat Plan was frozen following the enactment of Code Section 457A. No further contributions may be made to the Top Hat Plan.

Amounts credited to the Excess Benefit Plan and the Deferred Compensation Plan for U.S. Citizens became vested and non-forfeitable on the earliest of (i) December 31, 2008, (ii) the date on which the participant completed two years of service with us, or (iii) the participant’s death or disability. Amounts deferred under the Top Hat Plan are fully vested at all times. Contributions to the plans are deemed to be invested by each participant in one or more of the investment vehicles selected for this purpose by the committee administering the plans and/ or in the participant’s self-directed investment account and any earnings on these deemed investments are credited to the participant’s account under the plans. Except for amounts contributed to the plans with respect to 2005 (which are distributed only upon the participant’s separation from service, death or disability), payment under the plans will generally occur upon the earlier of (x) the participant’s separation from service, death or disability (y) a specific date (or dates) elected by the participant or (z) December 31, 2017.

Defined Contribution Plans

As of December 31, 2009, we, through Alterra Capital, Alterra Insurance, Alterra Europe and Alterra at Lloyd’s, maintained five defined contribution arrangements for our employees and the employees of our Bermuda, Irish and United Kingdom subsidiaries: (i) the Alterra Insurance National Pension Scheme for Bermudian employees and employees whose spouses are Bermudian; (ii) the Alterra Insurance Employee Benefit Trust (as described below) for certain non U.S. taxpayers who work in Bermuda; (iii) a 401(k) plan for U.S. taxpayers who work in Bermuda; (iv) the Alterra Europe Pension for employees of the operating subsidiaries in Ireland; and (v) the Scottish Widows Pension Scheme for the employees of our operating subsidiaries based in the United Kingdom.

Other than the Scottish Widows Pension Scheme, with respect to amounts contributed by an employee into the applicable deferred compensation plan of up to 5% of covered compensation, we match 100% to 200% of the employee’s contribution up to applicable covered compensation levels, subject to certain vesting requirements based on length of employment. The 401(k) plan for U.S. taxpayers who work in Bermuda has been amended to be a safe harbor plan within the meaning of the Code, effective as of January 1, 2008. We match 100% of the first 3% of qualified contributions and 50% of the next 2% up to a maximum of 4% of qualified contributions. All contributions are immediately 100% vested. With respect to the Scottish Widows Pension Scheme, we contribute 10% of the participating employee’s covered compensation.

The Alterra Insurance Employee Benefit Trust is a segregated trust offered to certain non-U.S. citizens. The trust is managed by Fiduciary Partners Trust Company Ltd. and permits the individual employee to direct investment of the funds allocated to his or her trust account.

46

As of December 31, 2009, we, through Alterra USA Holdings, maintained an additional “safe harbor” 401(k) plan within the meaning of the Code for employees located in the United States. We match 100% of the first 3% of qualified contributions and 50% of the next 2% up to a maximum of 4% of qualified contributions. All contributions are immediately 100% vested.

Potential Payments Upon Termination or Change in Control

W. Marston Becker. In the event his employment terminates for any reason, Mr. Becker is generally entitled to receive the following accrued amounts: (i) accrued but unpaid base salary; (ii) earned but unpaid bonus; and (iii) accrued vacation pay.

In the event that we terminate Mr. Becker’s employment without Cause (as defined below) during the term of his employment agreement, in addition to the accrued amounts set forth above, Mr. Becker will receive a pro-rata bonus (reflecting both the cash and restricted stock bonus components) for the year in which his employment terminates and severance in an amount equal to $1,500,000, of which $750,000 will be paid six months following the date of his termination and the remaining $750,000 will be paid in equal installments over the course of the following six months, in accordance with our regular payroll practices.

In the event that Mr. Becker’s employment terminates due to the expiration of the term of his employment agreement, in addition to the accrued amounts set forth above, Mr. Becker will receive a pro-rata bonus (reflecting both the cash and restricted stock bonus components) for the year in which his employment terminates and severance in an amount equal to $750,000, of which $375,000 will be paid six months following the date his employment terminates and the remaining $375,000 will be paid in equal installments over the course of the following six months, in accordance with our regular payroll practices.

In the event Mr. Becker’s employment terminates due to his death or disability (as defined below), in addition to the accrued amounts set forth above, Mr. Becker or his beneficiaries will receive a pro-rata bonus (reflecting both the cash and restricted stock bonus components) for the year in which his employment terminates.

In the event that Mr. Becker terminates his employment for Good Reason (as defined below) or in the event that his employment terminates for any reason following a change in control (as defined below), in addition to the accrued amounts set forth above, Mr. Becker will receive a pro-rata bonus (reflecting both the cash and restricted stock bonus components) for the year in which his employment terminates and severance in an amount equal to three times the sum of (i) and (ii) where (i) is his then current annual base salary and (ii) is the greater of his last paid bonus or target bonus for the year of termination (in each case, reflecting both the cash and restricted stock bonus components). One-half of the severance amount will be paid six months following the date his employment terminates and the remaining one-half will be paid in equal installments over the course of the following six months, in accordance with our regular payroll practices.

In addition, in the event that any payment or benefit made to Mr. Becker is subject to excise tax because it is made in connection with a change in control within the meaning of Code Section 280G, we will pay Mr. Becker an amount necessary to gross him up for the amount of the excise tax, plus any additional taxes, penalties or interest. However, we may reduce the payments or benefits due to Mr. Becker but only if reducing the payments or benefits by less than 15% in the aggregate would avoid the imposition of the excise tax.

47

Assuming Mr. Becker’s employment terminated or there was a change in control under each of the circumstances described above on December 31, 2009, such payments and benefits have an estimated value as outlined below of:

Event	Pro-Rated Bonus			Total Cash Severance			Value of Accelerated Equity(1)			Gross Up			Total
Termination without Cause		3,400,000	(2)		1,500,000	(3)		3,975,997	(4)		0			8,875,997
Termination upon Death or Disability		3,400,000	(2)		0			2,150,121	(5)		0			5,550,121
Termination upon Expiration of the Employment Agreement without similar offer of employment		3,400,000	(2)		750,000	(3)		3,975,997	(4)		0			8,125,997
Termination for Cause or without Good Reason		0			0			0			0			0
Termination for Good Reason or following a Change in Control		3,400,000	(2)		12,789,600	(6)		3,975,997	(4)		6,289,059	(7)		26,454,656
Termination upon Retirement		3,400,000	(2)		0			0	(8)		0			3,400,000
Change in Control Only(9)		0			0			3,975,997	(4)		0			3,975,997

(1)	Calculated as the sum of (i) the number of restricted shares that vest upon termination of employment multiplied by the closing price of our common shares on December 31, 2009 ($22.30) and (ii) the number of options vesting upon termination of employment multiplied by the difference between $22.30 and the applicable exercise price of the options, unless the result is negative in which case the value is determined to be $nil.
(2)	Assumes that pro-rated bonus equals total actual bonus for 2009 performance.
(3)	Equal to contractually stated severance amount.
(4)	Calculated assuming that all unvested restricted shares and options fully vest upon a change in control or termination of employment, as applicable.
(5)	Calculated assuming that the 33,333 restricted shares granted on February 19, 2009 fully vest and that all other unvested restricted shares vest on a pro-rata basis and that all unvested performance vesting options terminate.
(6)	Calculated as three times the aggregate of (i) Mr. Becker’s then current base salary and (ii) the greater of Mr. Becker’s last paid bonus or then current target bonus. Assumes target bonus equals 300% of current base salary.
(7)	Pursuant to his employment agreement, Mr. Becker under certain circumstances is entitled to receive a gross-up payment from us to make him whole as a result of any excise taxes that may be imposed upon him under Code Section 4999.
(8)	Calculated assuming that all unvested non-performance vesting restricted shares continue to vest per their original vesting schedule and all unvested performance vesting restricted shares and options terminate. Calculated using the closing price of our common shares on December 31, 2009 ($22.30), the unvested awards have a value of $2,793,922.
(9)	Mr. Becker is generally entitled to vesting of his equity awards upon a change in control. However, pursuant to the amalgamation, Mr. Becker has waived 100% of the accelerated vesting of equity awards that would have vested upon consummation of the amalgamation. This waiver does not apply to any other change in control event.

Notwithstanding the disclosure set forth in the table above, as a result of the amalgamation, should Mr. Becker’s employment terminate for any reason after May 12, 2010, such termination shall be deemed to be following a change in control and as such Mr. Becker will receive a pro-rata bonus for the year in which his employment terminates and severance in an amount equal to three times the sum of (i) and (ii) where (i) is his then current annual base salary and (ii) is the greater of his last paid bonus or target bonus for the year of termination (in each case, reflecting both the cash and restricted stock bonus components) and will be entitled to receive a gross-up payment from the Company to make him whole as a result of any excise taxes that may be imposed upon him under Code Section 4999.

48

Joseph W. Roberts, Peter A. Minton and Angelo M. Guagliano. Pursuant to the terms of the employment agreements for each of Messrs. Roberts, Minton and Guagliano (each, for purposes of this discussion, an “executive”), in the event that an executive’s employment terminates for any reason, he is generally entitled to receive the following accrued amounts: (i) accrued but unpaid base salary; (ii) accrued but unused vacation pay; and (iii) reimbursement for previously incurred reasonable business expenses. The executive will also be entitled to any other rights, compensation and benefits that may be due to him in accordance with the terms and provisions of any of our agreements, plans or programs.

In the event that an executive’s employment is terminated by us (or Alterra Insurance in the case of Mr. Guagliano) without Cause (as defined below) or by the executive for Good Reason (as defined below), in addition to the accrued amounts set forth above, the executive will receive any accrued but unpaid bonus, a pro-rated bonus (reflecting both the cash and restricted stock bonus components) payable for the year of termination of employment and regular severance in an amount equal to the sum of the executive’s then current annual base salary and the bonus (reflecting both the cash and restricted stock bonus components) last paid or payable to the executive in respect of the last completed fiscal year preceding termination. The regular severance is payable in twelve substantially equal monthly installments and is contingent upon the executive’s execution and non-revocation of a general release of claims in our favor. The pro-rated bonus for the year of termination is payable no later than March 15th of the calendar year following termination. In addition to the foregoing payments, Mr. Roberts will receive an additional 730 days of vesting credit (provided the total number of days of vesting credit does not exceed 1,095) in determining the vesting of 35,000 restricted shares that we granted Mr. Roberts in February 2007.

Notwithstanding the foregoing, in the event that an executive’s employment is terminated by us (or Alterra Insurance in the case of Mr. Guagliano) without Cause or by the executive for Good Reason in connection with, upon the occurrence of, or within twelve months following a change in control (as defined below), then in lieu of the above regular severance amount, the executive will receive enhanced severance in an amount equal to two times the sum of the executive’s then current annual base salary and target bonus (reflecting both the cash and restricted stock bonus components). The enhanced severance is payable in a lump sum, but with respect to Messrs. Minton and Guagliano, the portion of the enhanced severance that is equal to the regular severance is only payable in lump sum if the executive’s employment is terminated within twelve months following a change in control that constitutes a “change in control event” within the meaning of Code Section 409A. Otherwise, that portion of the enhanced severance is payable in monthly installments as set forth above. The regular or enhanced severance payments are made (or begin, in the case of installments) upon the expiration of the applicable release revocation period or six months following the date of the executive’s termination in the event that we determine that the executive is a “specified employee” and the severance is “nonqualified deferred compensation” within the meaning of Code Section 409A (with the first payment being a lump sum equal to the aggregate payments that would have been made during the prior six-month period, in the case of installments).

In the event that an executive’s employment terminates because we (or Alterra Insurance in the case of Mr. Guagliano) provide the executive with notice of our intent not to renew the term of his employment agreement, in addition to the accrued amounts set forth above, we will continue to pay the executive his then current base salary for six months following his termination, contingent upon the executive’s execution and non-revocation of a general release of claims in our favor. Payment of the executive’s continued base salary will begin upon the expiration of the applicable release revocation period unless we determine the executive is a “specified employee” and the severance is “nonqualified deferred compensation” within the meaning of Code Section 409A, in which case the continued base salary will be paid in lump sum six months following the executive’s termination.

In the event that an executive’s employment terminates due to his death or disability (as defined below), in addition to the accrued amounts set forth above, the executive or his beneficiaries will receive any accrued but unpaid bonus and a pro-rata bonus (reflecting both the cash and restricted stock bonus components) for the year in which his employment terminates.

49

In the event that an executive’s employment terminates due to his retirement, in addition to the accrued amounts set forth above, the executive will receive any accrued but unpaid bonus and a pro-rata bonus (reflecting both the cash and restricted stock bonus components) for the year in which he retires. Payment of the pro-rata bonus is contingent on the executive not engaging in employment, consulting, directorships or certain other relationships without the consent of our board (or Alterra Insurance’s board in the case of Mr. Guagliano).

Incentive Plans

54

executive officer’s employment agreement). Subject to certain limitations, if the service relationship is terminated as a result of the failure of the Bermuda immigration authorities to renew a Bermuda-based named executive officer’s work permit (through no fault of the employee), the named executive officer is eligible to receive full vesting of the outstanding restricted awards. For those share awards with retirement provisions, upon retirement the named executive officer’s award vesting schedule will remain unchanged. If the service relationship with the named executive officer ends for a reason other than those listed in this paragraph, the restricted shares will be forfeited and the named executive officer will have no rights with respect to the award.

Generally, our restricted share awards granted prior to February 8, 2010 provide that, upon termination of the named executive officer’s service relationship with us, the named executive officer will receive immediate vesting of a pro-rata portion of his restricted share awards if the termination of the service relationship resulted from (i) his death, (ii) termination by us due to the named executive officer’s disability (as defined below), (iii) termination by us without Cause (as defined in our 2000 Incentive Plan) or (iv) termination by the named executive officer for Good Reason (as defined in the named executive officer’s employment agreement).

Upon retirement, the named executive officer’s award vesting schedule will remain unchanged provided that, during the term of the vesting period, the named executive officer does not enter into to any employment, consulting, service or similar arrangements or accept any directorship that has not been pre-approved by our Compensation Committee. If the service relationship with the named executive officer ends for a reason other than those listed in this paragraph, the restricted shares will be forfeited and the named executive officer will have no rights with respect to the award.

With respect to options granted under our 2000 Incentive Plan, upon the named executive officer’s death or, as determined by our Compensation Committee, disability, or termination by us without Cause (as defined in the applicable Incentive Plan), all unvested options that would have vested in the one-year period following termination of employment automatically vest and become exercisable within the same one-year period. If the named executive officer’s employment is terminated for any other reason, all unvested options are forfeited and vested options are exercisable for 90 days following the termination of employment.

With respect to options granted under our 2008 Incentive Plan, upon the named executive officer’s death or, as determined by our Compensation Committee, disability, or termination by us without Cause (as defined in the applicable Incentive Plan) or, subject to limitations, the failure of the Bermuda immigration authorities to renew a Bermuda-based named executive officer’s work permit (through no fault of the employee), if applicable, and our failure to offer a comparable position with an affiliate, a pro-rata portion of the options that would have vested on the next grant anniversary date will vest as of the termination date and all other unvested options will be forfeited. Further, award recipients under our 2008 Incentive Plan are required to comply with restrictive covenants pertaining to safeguarding of the Company’s confidential information, non-disparagement and ownership of intellectual property.

Upon a change in control, all restrictions, if any, on any share awards, restricted shares, or restricted share units granted under our Incentive Plans will automatically lapse and all options will automatically vest and become immediately exercisable in full and all unvested warrants will become immediately vested.

Notwithstanding the termination provisions described above, pursuant to the terms of Mr. Becker’s employment agreement, unvested portions of option and restricted share awards granted to Mr. Becker (including any awards granted in the future) will immediately vest in full upon the occurrence of any of the following events (i) our termination of Mr. Becker’s employment without Cause (as defined in his employment agreement), (ii) termination of Mr. Becker’s employment for Good Reason (as defined in his employment agreement), (iii) termination following a change in control (as defined in his employment agreement) or (iv) termination at the end of the term.

55

Additionally, pursuant to the terms of Mr. Becker’s performance-based restricted share award granted February 19, 2009, if Mr. Becker’s employment is terminated on account of his death or disability (as defined in the employment agreement), he will receive immediate full vesting of this restricted share award.

Warrants. If Mr. Minton’s employment is terminated, his warrants, all of which are vested, will remain exercisable for (i) thirty days following his termination of employment if Mr. Minton’s termination is for Cause or without Good Reason, or (ii) six months following his termination of employment if Mr. Minton’s termination arises out of Disability, without Cause, for Good Reason (each as defined in the warrant agreement) or a failure of the Bermuda immigration authorities to renew his work permit.

Compensation Risk Management Disclosure

Our Compensation Committee considers the principal risk related to compensation for our employees to be that we may overcompensate individuals for underwriting business that ultimately is not profitable given that much of our insurance and reinsurance business is long-tail and we cannot predict with certainty how claims will develop or our future operating performance related thereto. Accordingly, in an effort to align our employees’ economic interests with our economic interests, underwriting performance is assessed on a rolling three-year basis in addition to current-year results. Further, our compensation program encourages consistent long-term performance by allocating a significant portion of executive bonus awards in the form of restricted stock with vesting after three years in most instances. The time based vesting over three years helps ensure that our executives’ interests align with ours and our stockholders. In those instances where performance is a prerequisite for vesting, our Compensation Committee sets performance goals that it believes are reasonable in light of our past performance and general market conditions. As a result of the foregoing, our Compensation Committee believes our compensation programs are appropriately structured and do not pose a material risk to us.

Director Compensation

We currently have 12 directors who are eligible to receive compensation for their services as directors, all of whom are non-employee directors. Neither Messrs. Becker nor Berger receives additional compensation for serving as a member of our board of directors.

At each annual general meeting, each non-employee director receives a $50,000 annual retainer, the ARMC chairman receives a $25,000 annual retainer, the Compensation Committee chairman receives a $15,000 annual retainer and each other committee chair receives a $10,000 annual retainer. Non- employee directors are paid board and committee meeting fees of $2,500 per meeting. Beginning with the Meeting, the non-executive chairman of the board will also receive a $100,000 annual retainer. In addition, to the extent that a director performs specific tasks on behalf of and at the direction of the board, we may compensate such director on a per diem basis in an amount equal to a meeting fee. Along with cash compensation, on the day following the annual general meeting, each non employee director receives either 4,000 restricted shares or 4,000 restricted share units. We reimburse directors for usual and customary expenses while on company business. In addition, we reimburse directors for expenses for family members to accompany them to one board meeting per year.

The compensation of our directors is reviewed annually and revisions to our non-employee directors’ compensation will be made upon the recommendation of the Nominating and Corporate Governance Committee, subject to such conditions or restrictions, if any, that such committee or our Compensation Committee may determine.

Report of the Audit and Risk Management Committee

Management has the primary responsibility for establishing and maintaining adequate internal financial controls, preparing the financial statements and administrating the public reporting process. The ARMC’s primary purpose is to assist our board of directors in fulfilling its responsibilities to oversee the participation of management in the financial reporting process and the role and responsibilities of the independent auditors. For 2009, the ARMC was composed of five directors, each of whom our board of directors has determined is independent under Nasdaq Global Select Market listing standards and applicable rules promulgated under the Exchange Act and operates under a written charter adopted and approved by our board of directors, and which is available on our website at www.maxcapgroup.com.

The ARMC has reviewed and discussed the December 31, 2009 audited consolidated financial statements with management and with KPMG, Hamilton, Bermuda, our independent auditors. In addition, the ARMC has discussed with KPMG and management, and monitored quarterly compliance with, Section 404 of the Sarbanes-Oxley Act of 2002 regarding internal controls over financial reporting.

The ARMC has also discussed with KPMG the matters required to be discussed by Statement on Auditing Standards No. 61, as amended (AICPA, Professional Standards, Vol. 1. AU Section 380) as adopted by the Public Company Accounting Oversight Board in Rule 3200T. This included (a) the auditor’s judgments about the quality, not just the acceptability, of the accounting principles as applied to Alterra Capital’s financial reporting, (b) the methods used to account for significant unusual transactions, (c) the effect of significant accounting policies in controversial or emerging areas for which there is a lack of authoritative guidance or consensus, (d) the process used by management in formulating particularly sensitive accounting estimates and the basis for the auditor’s conclusions regarding the reasonableness of those estimates and (e) disagreements with management over the application of accounting principles, the basis for management’s accounting estimates, and disclosures in the financial statements.

The ARMC has discussed with KPMG the written disclosures and the letter required by applicable requirements of the Public Company Accounting Oversight Board regarding the independent auditor’s communications with the audit committee concerning independence, and has discussed with KPMG their independence. The ARMC has also discussed with KPMG the rotation of independent auditor partners, compliance procedures and the certification of Forms 10-K and Form 10-Q as required by the Sarbanes-Oxley Act of 2002.

Based on the review and discussions referred to above, and in reliance on the information, opinions, reports or statements presented to the ARMC by management and the independent auditors, the ARMC recommended to our board of directors that the December 31, 2009 audited consolidated financial statements be included in the Annual Report on Form 10-K.

The Audit and Risk Management Committee
(For fiscal year 2009)

Mario P. Torsiello (Chairman)
K. Bruce Connell
James H. MacNaughton
James L. Zech

The foregoing Report of the Audit and Risk Management Committee shall not be deemed to be incorporated by reference in any previous or future documents filed by Alterra Capital with the SEC under the Securities Act of 1933, as amended, or the Exchange Act, except to the extent that Alterra Capital specifically incorporates the Report by reference in any such document.

Principal Accountant Fees and Services

Audit Fees

The aggregate amount of fees billed by KPMG for professional services rendered for the audit of our financial statements for the fiscal years ended December 31, 2009 and December 31, 2008 and for the review of the financial statements included in our Quarterly Reports on Form 10-Q in 2009 and 2008 were $2,532,170 and $2,500,959, respectively. In 2009 and 2008, audit fees also included fees for professional services rendered in connection with the issuance of an opinion on the effectiveness of our internal control over financial reporting based upon the audit. Such fees did not include amounts paid for reimbursement of expenses.

Audit-Related Fees

The aggregate amount of fees billed by KPMG for assurance and related services that were reasonably related to the performance of the audit or review of our financial statements (and are not included in the Audit Fees reported above) for the fiscal years ended December 31, 2009 and December 31, 2008 were $248,161 and $32,980, respectively. Audit-related fees in 2009 and 2008 represented fees for the review of registration statements and offering documents.

Tax Fees

The aggregate amount of fees billed by KPMG for professional services rendered for tax compliance and tax advice for the fiscal years ended December 31, 2009 and December 31, 2008 were $337,759 and $165,950, respectively. These fees represented fees for professional services related to the preparation of returns and tax compliance.

All Other Fees

The fees billed by KPMG for services rendered to us in connection with due diligence work for the fiscal year ended December 31, 2009 was $183,592. For the fiscal year ended December 31, 2008, there were no fees billed other than for services described under “Audit Fees,” “Audit-Related Fees” and “Tax Fees” above.

General

The ARMC has considered whether the provision of non-audit services performed by the independent auditors is compatible with maintaining KPMG’s independence and has concluded that services to be performed by KPMG are generally limited to audit and tax services but may include other services. Any services provided by KPMG in addition to audit and tax related services are performed subject to our pre-approval policy.

Pre-Approval of Audit and Non-Audit Services

In 2003, the ARMC adopted a policy concerning the approval of audit and non-audit services, i.e. tax fees, to be provided to us by the independent auditor. The policy requires that all services KPMG, our independent auditor, may provide to us, including audit services and permitted audit-related and non-audit services, be pre-approved by the ARMC, except that we may, without such pre-approval, spend an amount on non-audit services of not more than 10% of the total amount of fees paid by us to our auditor during the fiscal year in which the non-audit services are performed. The ARMC approved all audit and non-audit services provided by KPMG during 2009.

Section 16(a) Beneficial Ownership Reporting Compliance

The U.S. federal securities laws require the filing of certain reports by officers, directors and beneficial owners of more than ten percent (10%) of Alterra Capital’s securities with the SEC. Specific due dates have been established and we are required to disclose any failure to file by these dates. Based solely on a review of information furnished to us, we believe that during fiscal year 2009, our officers, directors and 10% shareholders satisfied all such filing requirements, with the exception of one Form 4 filed five days late for Mr. Becker, our Chief Executive Officer and one of our directors, in connection with the forfeiture of certain restricted shares.

Shareholder Proposals for Annual General Meeting of Shareholders in 2011

Shareholder proposals must be received in writing by the Secretary of Alterra Capital and must comply with Rule 14a-8 of the Securities Exchange Act of 1934, the requirements of Bermuda corporate law and Alterra Capital’s bye-laws in order to be considered for inclusion in our Proxy Statement and form of Proxy relating to such meeting. We believe that shareholder proposals received by November 16, 2010 would be considered timely for inclusion in the 2011 Proxy Statement. Such proposals should be directed to the attention of the Secretary, Alterra Capital Holdings Limited, P.O. Box HM 2565, Hamilton HM KX, Bermuda.

Shareholders who intend to nominate persons for election as directors at general meetings of Alterra Capital must comply with the advance notice procedures and other provisions set forth in the bye-laws of Alterra Capital in order for such nominations to be properly brought before the general meeting.

Any such recommendation shall also include: (i) the names and addresses of the shareholders who intend to make the nomination and of the person or persons to be nominated; (ii) a representation that such shareholders are holders of record of shares entitled to vote at such meeting and intend to appear in person or by proxy at the meeting to nominate the person or persons specified in the recommendation; (iii) the class and number of shares which are beneficially owned by such shareholders; (iv) a description of all arrangements or understandings between such shareholders and each nominee and any other person or persons nominations are to be made by such shareholders; and (v) such other information regarding each nominee proposed by such shareholders as would be required to be included in a proxy statement filed pursuant to Regulation 14A under the Exchange Act. The Nominating and Corporate Governance Committee may refuse to acknowledge the nomination of any person not made in compliance with the foregoing procedure.

Any shareholder proposal for the 2011 annual general meeting, other than with respect to a nominee for election as a director, which is submitted outside the processes of Rule 14a-8 shall be considered untimely unless received by the Secretary in writing no later than November 16, 2010. If a shareholder proposal is introduced at the 2011 annual general meeting of shareholders without any discussion of the proposal in the 2011 Proxy Statement and the shareholder does not notify Alterra Capital of the intent to raise such proposal at the annual general meeting of shareholders, then

64

proxies received by Alterra Capital for the 2011 annual general meeting of shareholders will be voted by the persons named as such proxies in their discretion with respect to such proposal.
