PROXY STATEMENT
ANNUAL GENERAL MEETING OF SHAREHOLDERS
May 2, 2007

GENERAL INFORMATION

This Proxy Statement is furnished in connection with the solicitation of proxies on behalf of the Board of Directors (the ‘‘Board’’) of Aspen Insurance Holdings Limited (the ‘‘Company’’) to be voted at our annual general meeting of shareholders (the ‘‘Shareholders’’) to be held at the offices of the Company, Maxwell Roberts Building, 1 Church Street, Hamilton HM11 Bermuda on May 2, 2007 at 12:00 p.m. Bermuda time, or at such other meeting upon any postponement or adjournment thereof (the ‘‘Annual General Meeting’’). This Proxy Statement, the Notice of Annual General Meeting of Shareholders and the accompanying form of proxy are being first mailed to Shareholders on or about March 28, 2007.

As of March 8, 2007, the record date for the determination of persons entitled to receive notice of, and to vote at, the Annual General Meeting, there were 87,821,186 ordinary shares of the Company, par value U.S. 0.15144558¢ per share (the ‘‘ordinary shares’’), issued and outstanding. The ordinary shares are our only class of equity securities outstanding and entitled to vote at the Annual General Meeting.

Holders of ordinary shares are entitled to one vote on each matter to be voted upon by the Shareholders at the Annual General Meeting for each share held. Pursuant to our Bye-Laws 63 to 67, the voting power of all ordinary shares is adjusted to the extent necessary so that there is no 9.5% U.S. Shareholder. For the purposes of our Bye-Laws, a 9.5% U.S. Shareholder is defined as a United States Person (as defined in the Internal Revenue Code of 1986, as amended, of the United States (the ‘‘Code’’)) whose ‘‘controlled shares’’ (as defined below) constitute nine and one-half percent or more of the voting power of all ordinary shares of the Company and who would be generally required to recognize income with respect to the Company under Section 951(a)(1) of the Code, if the Company were a controlled foreign corporation as defined in Section 957 of the Code and if the ownership threshold under Section 951(b) of the Code were 9.5%.

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, the Company requests that any holder of ordinary shares with reason to believe that it is a 9.5% U.S. Shareholder (as described above) contact the Company promptly so that the Company may determine whether the voting power of such holder’s ordinary shares should be reduced. By submitting a proxy, unless the Company has otherwise been notified or made a determination with respect to a holder of ordinary shares, a holder of ordinary shares will be deemed to have confirmed that, to its knowledge, it is not, and is not acting on behalf of , a 9.5% U.S. Shareholder.

In order to determine the number of controlled shares owned by each Shareholder, we are authorized to require any Shareholder to provide such information as the Board may deem necessary for the purpose of determining whether any Shareholder’s voting rights are to be adjusted pursuant to the Company’s Bye-Laws. We may, in our reasonable discretion, disregard the votes attached to ordinary shares of any Shareholder failing to respond to such a request or submitting incomplete or inaccurate information. ‘‘Controlled shares’’ will include, among other things, all ordinary shares that a person is deemed to beneficially own directly, indirectly or constructively (as determined pursuant to Sections 957 and 958 of the Code).

The presence of one or more Shareholders in person or by proxy holding at least 50% of the voting power (that is the number of maximum possible votes of the Shareholders entitled to attend and vote at a general meeting, after giving effect to the provision of our Bye-Laws 63 to 67) of all of the issued and outstanding ordinary shares of the Company throughout the meeting shall form a quorum for the transaction of business at the Annual General Meeting.

Pursuant to our Bye-Laws 63 to 67, it is currently expected that there will be no adjustments to the voting power, since there does not appear to be any Tentative 9.5% U.S. Shareholder (as defined in our Bye-Laws). Therefore, every Shareholder will be entitled to one vote per each matter to be voted upon for each ordinary share held by such Shareholder.

The Company’s Bye-Law 84 provides that, if the Company is required or entitled to vote at a general meeting of any of its subsidiaries organized under the laws of a jurisdiction outside the United States of America (each, a ‘‘Non-U.S. Subsidiary’’), the Board shall refer the subject matter of the vote to the Shareholders of the Company on a poll and seek authority from the Shareholders in a general meeting of the Company for the Company’s corporate representative or proxy to vote in favor of the resolutions proposed by such Non-U.S. Subsidiary. The Board shall cause the Company’s corporate representative or proxy to vote the Company’s shares in the Non-U.S. Subsidiary pro rata to the votes received at the general meeting of the Company, with votes for or against the directing resolution being taken, respectively, as an instruction for the Company’s corporate representative or proxy to vote the appropriate proportion of its shares for, and the appropriate proportion of its shares against, the resolution proposed by the Non-U.S. Subsidiary.

PRESENTATION OF FINANCIAL STATEMENTS

In accordance with the Companies Act 1981 of Bermuda and Bye-Law 140 of the Company, the Company’s financial statements for the year ended December 31, 2006 will be presented at the Annual General Meeting. The Board has approved these statements. There is no requirement under Bermuda law that these statements be approved by Shareholders, and no such approval will be sought at the meeting.

SOLICITATION AND REVOCATION

PROXIES IN THE FORM ENCLOSED ARE BEING SOLICITED BY, OR ON BEHALF OF, THE BOARD. THE BOARD HAS DESIGNATED THE PERSONS NAMED IN THE ACCOMPANYING FORM OF PROXY AS PROXIES. Such persons designated as proxies serve as officers of the Company. Any Shareholder desiring to appoint another person to represent him or her at the Annual General Meeting may do so either by inserting such person’s name in the blank space provided on the accompanying form of proxy, or by completing another form of proxy and, in either case, delivering an executed proxy to the Secretary of the Company at the address indicated above, before the time of the Annual General Meeting. It is the responsibility of the Shareholder appointing such other person to re present him or her to inform such person of this appointment.

Each ordinary share represented by a properly executed proxy which is returned and not revoked will be voted in accordance with the instructions, if any, given thereon. If no instructions are provided in a properly executed 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 proxyholder’s best judgment as to any other business as may properly come before the Annual General Meeting. If a Shareholder appoints a person other than the persons named in the enclosed form of proxy to represent him or her, such person will vote the shares in respect of which he or she is appointed proxyholder in accordance with the directions of the Shareholde r appointing him or her. Any Shareholder who

executes a proxy may revoke it at any time before it is voted by delivering to the Secretary of the Company a written statement revoking such proxy, by executing and delivering a later dated proxy, or by voting in person at the Annual General Meeting. Attendance at the Annual General Meeting by a Shareholder who has executed and delivered a proxy to us shall not in and of itself constitute a revocation of such proxy. For ordinary shares held in ‘‘street name’’ by a broker, bank or other nominee, new voting instructions must be delivered to the broker, bank or nominee prior to the Annual General Meeting.

Because the Company is currently a foreign private issuer, to the extent that beneficial owners do not furnish voting instructions with respect to any or all proposals submitted for shareholder action, member brokerage firms of The New York Stock Exchange, Inc. (the ‘‘NYSE’’) that hold ordinary shares in street name for such beneficial owners may not vote in their discretion upon any of the proposals. Any ‘‘broker non-votes’’ and abstentions will be counted toward the presence of a quorum at, but will not be considered votes cast on any proposal brought before the Annual General Meeting. Generally, ‘‘broker non-votes’’ occur when ordinary shares held for a ben eficial owner are not voted on a particular proposal because the broker has not received voting instructions from the beneficial owner, and the broker does not have discretionary authority to vote the ordinary shares on a particular proposal. If a quorum is not present, the Shareholders who are represented may adjourn the Annual General Meeting until a quorum is present. The time and place of the adjourned meeting will be announced at the time the adjournment is taken, and no other notice need be given. An adjournment will have no effect on the business that may be conducted at the adjourned meeting.

We will bear the cost of solicitation of proxies. We have engaged Mellon Investor Services LLC to be our proxy solicitation agent. For these services, we will pay Mellon Investor Services LLC a fee of approximately $8,500, plus expenses. Further solicitation may be made by our directors, officers and employees personally, by telephone, Internet or otherwise, but such persons will not be specifically compensated for such services. We may also make, through bankers, brokers or other persons, a solicitation of proxies of beneficial holders of the ordinary shares. Upon request, we will reimburse brokers, dealers, banks or similar entities acting as nominees for reasonable expenses incurred in forwarding copies of the proxy materials r elating to the Annual General Meeting to the beneficial owners of ordinary shares which such persons hold of record.

Executive Compensation

COMPENSATION DISCUSSION AND ANALYSIS

Overview

This section provides information regarding the compensation program for our Chief Executive Officer, Chief Financial Officer and the three other most highly-compensated executive officers (‘‘NEOs’’) for 2006. We have also included information on a senior executive who left the company and who would have been included otherwise as one of the three most highly-compensated executive officers. This section describes the overall objectives of our compensation program and each element of compensation.

The Company has achieved considerable growth since its inception in 2002 and our compensation programs and plans have been designed to reward executives who contribute to the continuing success of the Company.

The Compensation Committee of our board of directors (the ‘‘Compensation Committee’’) has responsibility for approving the compensation program for our NEOs. The Compensation Committee consists of four independent directors: Prakash Melwani (Chair), Julian Avery, Glyn Jones and Kamil Salame.

Our compensation policies are designed with the goal of maximizing shareholder value creation over the long term. The basic objectives of our executive compensation program are to:


	•	attract and retain highly skilled executives;


	•	link compensation to achievement of the Company’s financial and strategic goals by having a significant portion of compensation be performance-based;


	•	create commonality of interest between management and shareholders by tying substantial elements of compensation directly to changes in shareholder value;


	•	maximize the financial efficiency of the overall program from a tax, accounting, and cash flow perspective;


	•	ensure compliance with the highest standards of corporate governance; and


	•	encourage executives to work hard for the success of the business and work effectively with clients and colleagues for the benefit of the business as a whole.

We encourage a performance-based culture throughout the Company and at senior levels we have developed an approach to compensation which aligns the performance and contribution of the executive to the results of the Company. Fixed pay such as salary is balanced by variable compensation, such as bonuses and equity-based awards. All employees including senior executives are set challenging goals and targets both at an individual and team level, which they are expected to achieve, taking into account the dynamics which occur within the market and business environment. Equity awards encourage risk-sharing with shareholders and align executive pay with the value created for shareholders.

Executive Compensation Program

The Company’s compensation program consists of the following five elements:


	•	base salary;


	•	annual cash bonuses;


	•	long-term incentive awards;


	•	other stock plans; and


	•	benefits and perquisites.

The Committee seeks to consider all elements that contribute to the total compensation of NEOs rather than consider each element in isolation. We actively seek market intelligence on all aspects of pay and benefits.

Market Intelligence. We believe that shareholders are best served when the compensation packages of senior executives are competitive but fair. The Committee seeks to create a package that delivers total compensation packages for NEOs at the upper quartile of the total compensation delivered by certain peer companies for exceeding performance against competitors and the Company’s internal business targets.

We seek external market data to ensure that our compensation levels are competitive. Our sources of information include:


	•	research of peer company annual reports on Form 10-K and similar filings for companies in our sector in the markets in which we operate;


	•	publicly available salary surveys from reputable survey providers;


	•	advice and tailored research from compensation consultants; and


	•	experience from recruiting senior positions in the market place.

To assist in making competitive comparisons, the Committee engaged PwC Consulting to provide information regarding the compensation practices of all peer group (as defined below) and other additional companies against which we compete. The peer group includes Endurance Specialty Holdings Ltd., Arch Capital Group Ltd., Transatlantic Holdings, Inc., PartnerRe Ltd., Axis Capital Holdings Limited, Max Re Capital Ltd., Platinum Underwriters Holdings, Ltd., RenaissanceRe Holdings Ltd., Everest Re Group, Ltd., IPC Holdings, Ltd. and Montpelier Re Holdings Ltd. Additional companies researched for compensation and benefit information include ACE Limited, XL Capital Ltd, Catlin Group Limited, Brit Insurance Holdings PLC, Wellington Underwri ting plc, Amlin plc, Hiscox Ltd, Kiln plc, Beazley Group plc and Chaucer Holdings PLC.

In 2006, the Compensation Committee retained Frederic W Cook & Co. and New Bridge Street Consulting as independent advisors following a rigorous selection process.

Cash Compensation

Base Salary. Base salaries are determined taking into account the relative importance of the position, the competitive market place, and the individual executive officer’s experience, skills, knowledge and responsibilities in their roles. Salaries are reviewed annually. The Committee reviews the compensation, including base salary, of the top 20 employees in the Company, including the NEOs.

When reviewing base salaries, the Compensation Committee and management considered a range of factors including:


	•	the performance of the business;


	•	the performance of the executives in their roles over the previous year;


	•	the historical context of the executives compensation awards;


	•	the responsibilities of the role;


	•	the experience brought to the role by the executive;


	•	the function undertaken by the role; and


	•	analysis of the market data from competitors and more general market data from labour markets in which we operate.

Executive officers have employment agreements with the Company that specify their base salary. They are entitled to a review on an annual basis, with any changes effective as of April 1^st of the relevant year. Even though we conduct an annual review of base salaries, we are not legally obligated

to increase salaries. We are not contractually able to decrease salaries either. Otherwise, the Committee is free to set NEO salaries at the level that it deems appropriate. The Compensation Committee is generally mindful of its overall goal to pay base salaries at the median percentile against the peer group of companies and against the market for similar roles in the market in which the NEO is employed. The Compensation Committee does not apply this principle mechanically but takes into account the factors outlined above and the total compensation picture for each individual.

Annual Cash Bonuses. The Company operates a discretionary bonus plan. Annual cash bonuses are intended to reward executives for their achievements and contributions to the success of the business over the previous fiscal year. The Compensation Committee determines the bonus pool available to employees based on the Company’s net income after tax and specifically approves the bonuses for the top 30 employees in the Company, including the NEOs.

In 2006 we reviewed the bonus program. We benchmarked our bonus payouts with our competitive peer group and other market data to establish our position in the market. We used this information to assist us in developing a methodology for establishing the size of the bonus pool required for the Company as a whole and to establish individual bonus potentials for all employees, including the NEOs. The bonus potentials are indicative and do not set a maximum limit. For example, in a loss-making year, employees may not get any bonuses. Conversely, in profitable years, employees may receive bonuses in excess of their bonus potentials.

Once the bonus pool is established, teams are allocated portions of the bonus pool based on their team performance. Individuals, including the NEOs, are allocated on their individual contribution to the business. An individual’s contribution is assessed based on his or her accomplishment of set objectives established at their annual performance review, such as enhanced efficiencies and expense reductions, and any other material achievements. In the case of the Chief Executive Officer, the Compensation Committee assesses his performance against the Company’s business plan and other objectives established by the board of directors.

For 2006, the Compensation Committee established bonus potentials in the range of 115% to 135% of base salary for our NEOs other than our Chief Executive Officer, for whom a bonus potential was not established.

Equity Compensation

The Compensation Committee believes that a substantial portion of each NEOs compensation should be in the form of equity awards and that such awards serve to align the interests of NEOs and our shareholders. Equity awards to our NEOs are made pursuant to the Aspen Insurance Holdings Limited 2003 Share Incentive Plan, as amended (‘‘2003 Share Incentive Plan’’). The 2003 Share Incentive Plan was last amended at our annual general meeting in 2005 to increase the number of shares that can be issued under the plan. The total number of ordinary shares that may be issued under the 2003 Share Incentive Plan is 9,476,553. As of December 31, 2006, 5,437,417 options and equity awards (including restricted share unit s) were outstanding under our 2003 Share Incentive Plan.

Long-Term Incentive Awards. The Company operates an annual Long Term Incentive Plan (‘‘LTIP’’) for key employees under the 2003 Share Incentive Plan. The LTIP grant consists of performance shares and options. The mix of shares and options varies with seniority. For senior executives, including all NEOs, the distribution between performance shares and options granted is 25% and 75%, respectively. For this purpose, we use the grant date fair value of the options. We award a greater proportion in the form of options to senior executives to align the economic interests of senior executives with increased shareholder value. In 2006, we granted options and performance share awards to 129 employees.

All performance shares and options granted in 2006 have performance conditions. The performance conditions are identical for both shares and options and all are subject to a three-year vesting period. The material terms for the 2006 options and share awards are summarized as follows:


	•	one-third of the grants are earned based on achievement of a one-year Return on Equity (‘‘ROE’’) performance target in accordance with the Company’s 2006 business plan, which in 2006 was set at approximately 15%;


	•	two-thirds of the grants become eligible for vesting if a performance condition, based on the average three-year ROE performance for 2006, 2007 and 2008, is met. Average ROE performance is measured against the ROE targets set for each of the three years;


	•	there is a reduction in the number of performance shares and options which vest based on a sliding scale if the performance of the Company falls below (i) the performance target ROE for one-third of the grant, and (ii) the average ROE performance, for two-thirds of the grant;


	•	no performance shares or options vest if the Company’s average annual ROE for 2006, 2007 and 2008 falls below 10% ROE;


	•	the number of earned options and performance shares vest at the end of the three-year period, subject to continued employment; and


	•	in respect of options, the options expire on the tenth anniversary of the date of grant.

With respect to the 2006 performance shares and options, one-third of the initial grant is available for vesting as the ROE target was achieved. With respect to the 2004 performance shares, of which one-third of the grant is earned based on the achievement of the 2004 ROE target and two-thirds have a performance condition based on an average three-year (2004-2006) ROE, 17.16% of the total grant of 2004 performance shares have vested. The remainder of the 2004 performance share grants is forfeited due to the non-achievement of performance targets.

The number of performance shares and options available for grant each year are determined by the Committee. The Compensation Committee takes into account the number of available shares remaining under the 2003 Share Incentive Plan, the number of employees who will be participating in the plan, market data from competitors in respect of the percentage of outstanding shares made available for annual grants to employees and the need to retain and motivate key employees. In 2006, 1,532,602 options and performance shares were granted.

The Compensation Committee has generally followed a practice of making all option grants to its executive officers on a single date each year, except for new hires. For the last two years, the Committee has granted these annual awards at its regularly-scheduled meeting in February. The February meeting date has historically occurred at the same time as the release of our earnings for the previous fiscal year.

Beginning in 2007, we have adopted a policy whereby the Compensation Committee will continue to approve annual grants at a regularly scheduled meeting. However, if such meeting takes place while the Company is in a close period (i.e. prior to the release of our earnings), the grant date will be the day on which our close period ends, and the exercise price will be based on the average of the high and low price of our shares on such date, in accordance with our 2003 Share Incentive Plan.

While the bulk of our option awards to NEOs have historically been made pursuant to our annual grant program, the Committee retains the discretion to make additional awards at other times, in connection with the initial hiring of a new officer, for retention purposes or otherwise. We refer to such grants as ‘‘ad hoc’’ awards. In 2006, the only ad hoc grant was made to Mr. Sinclair, one of our NEOs, in connection with his hiring. If ad hoc grants are made while not in a close period, then the grant date will be the later of the date on which the Compensation Committee approves the grant or the effective date of employment of a new hire.

All option awards made to our NEOs, or any of our other employees or directors, are made pursuant to our 2003 Share Incentive Plan. As noted above, all options under the 2003 Share Incentive Plan are granted with an exercise price equal to the fair market value of our ordinary shares on the date of grant, being not less than the average of the high and low share price on the date of grant.

Other Stock Grants. The company awards time-vesting restricted share units (‘‘RSUs’’) selectively to employees under certain circumstances. RSUs vest solely based on continued service and are not subject to performance conditions. Typically, RSUs have been used to compensate newly hired executives for loss of stock value from awards that were forfeited when they left their previous company. The RSUs granted vest in one-third tranches over three years.

Benefits and Perquisites

Perquisites. Our NEOs receive various perquisites provided by or paid by the Company. These perquisites include housing allowances, club memberships and return flights to home country for executives and family for those working outside of their home country.

Many of these perquisites relate to those NEOs who transferred to our Bermuda operation and are typical of perquisites provided to expatriate employees located in Bermuda. Similar perquisites are provided by our competitors for employees in a similar set of circumstances and have been necessary for recruitment and retention purposes. These are:

Housing Allowance. Non-Bermudians are prevented by law from owning property in Bermuda. This has lead to a housing market that is largely based on renting to expatriates who work on the island. Housing allowances are a near universal practice for expatriates and also, increasingly, for local Bermudians in key positions. We base our housing allowances on market information available through local benefits surveys and from information available from the housing market. The allowance is based on the level of the position compared with market data.

Club Membership. This is common practice in the Bermudan market place and enables the expatriate to settle into the community. It also has the benefit of enabling our NEOs to establish social networks with clients and executives in our industry in furtherance of our business.

Home Leave. This is common practice for expatriates who are working outside of their home country. We believe that this helps the expatriate and his/her family keep in touch with the home country in respect of both business and social networks. Such a benefit is provided by other companies within our peer group, is necessary for both recruitment and retention purposes and is important for the success of the overseas assignment.

Change in Control and Severance Benefits

In General. We provide the opportunity for certain of our NEOs to be protected under the severance and change in control provisions contained in their employment agreements. We provide this opportunity to attract and retain an appropriate caliber of talent for the position. Our severance and change in control provisions for the named executive officers are summarized in ‘‘Narrative Description of Summary Compensation and Grants of Plan-Based Awards — Employment-Related Agreements’’ and ‘‘— Potential Payments upon Termination or Change in Control’’ below.

The following Summary Compensation Table sets forth, for the year ended December 31, 2006, the compensation for services in all capacities earned by the Company’s Chief Executive Officer, Chief Financial Officer, its next three most highly compensated executive officers, and an executive officer who no longer served as an executive officer as at the end of December 31, 2006.

(5)

Valuation is based on the dollar amount of performance share awards and restricted share unit grants recognized for financial statement purposes pursuant to FAS 123(R). For performance share awards, the FAS 123(R) value is $21.85 for the performance shares granted February 16, 2006 and $21.39 for the performance shares granted on August 4, 2006. For restricted share units, the FAS 123(R) value is the closing price of $23.01 on August 4, 2006, the date of grant. Refer to Note 14 of our financial statements with respect to our performance share awards and restricted share units.

(1)	For a description of the terms of the grants and the related vesting schedule, see ‘‘Narrative Description of Summary Compensation and Grants of Plan-Based Awards — Share Incentive Plan’’ above.


(2)	Calculated based upon the closing price of $26.36 per share of the Company’s ordinary shares at December 29, 2006, less the option exercise price.


(3)	As the performance targets for the 2004 options were not fully met based on the 2004 ROE achieved, 51.48% of the grant vested and the remaining portion of the grant was forfeited.

(4)

With respect to the 2004 performance shares, of which one-third of the grant is earned based on the achievement of the 2004 ROE target and two-thirds have a performance condition based on an average three-year (2004-2006) ROE, the amount represents 17.16% of the total grant of 2004 performance shares which will vest in the first quarter of 2007. The remainder of the 2004 performance share grants is forfeited due to the non-achievement of performance targets.


(5)	As the performance targets have not been met, the 2005 options were forfeited.

(6)

With respect to the 2005 performance shares, of which one-third of the grant is earned based on the achievement of the 2005 ROE target and two-thirds have a performance condition based on an average three-year (2005-2007) ROE, one-third of the grants has been forfeited as the 2005 ROE target has not been met. The amounts presented in the table assume that the performance conditions of the remaining two-thirds of the grant will be met. It is unlikely that the 2005 performance share awards will be eligible for vesting due to our losses in 2005.


(7)	As Ms. Davies’s employment with the Company was terminated as of December 31, 2006, all performance shares have been forfeited as such performance shares are only issuable upon vesting subject to the employee’s continued employment at the time of vesting.

Option Exercised and Stock Vested

The following table summarizes stock option exercises and share issuances by our named executive officers during the twelve months ended December 31, 2006:

(4)

The total cash payout and the acceleration of vesting are provided only if the employment of the above named executive is terminated by the Company without Cause or by the executive with Good Reason within the six-month period prior to a change in control or within a two-year period after a change in control. The occurrence of any of the following events constitutes a ‘‘Change in Control’’:

(A) the sale or disposition, in one or a series of related transactions, of all or substantially all, of the assets of the Company to any person or group (other than (x) any subsidiary of the Company or (y) any entity that is a holding company of the Company (other than any holding company which became a holding company in a transaction that resulted in a Change in Control) or any subsidiary of such holding company);

(B) any person or group is or becomes the beneficial owner, directly or indirectly, of more than 30% of the combined voting power of the voting shares of the Company (or any entity which is the beneficial owner of more than 50% of the combined voting power of the voting shares of the Company), including by way of merger, consolidation, tender or exchange offer or otherwise; excluding, however, the following: (i) any acquisition directly from the Company, (ii) any acquisition by the Company, (iii) any acquisition by any employee benefit plan (or related trust) sponsored or maintained by the Company or any corporation controlled by the Company, or (iv) any acquisition by a person or group if immediately after such acquisition a pe rson or group who is a shareholder of the Company on the effective date of our Share Incentive Plan continues to own voting power of the voting shares of the Company that is greater than the voting power owned by such acquiring person or group;

(C) the consummation of any transaction or series of transactions resulting in a merger, consolidation or amalgamation, in which the Company is involved, other than a merger, consolidation or amalgamation which would result in the shareholders of the Company immediately prior thereto continuing to own (either by remaining outstanding or by being converted into voting securities of the surviving entity), in the same proportion as immediately prior to the transaction(s), more than 50% of the combined voting power of the voting shares of the Company or such surviving entity outstanding immediately after such merger, consolidation or amalgamation; or

(D) a change in the composition of the Board such that the individuals who, as of the effective date of the Share Incentive Plan, constitute the board of directors (such board of directors shall be referred to for purposes of this section only as the ‘‘Incumbent Board’’) cease for any reason to constitute at least a majority of the Board; provided, however, that for purposes of this definition, any individual who becomes a member of the board of directors subsequent to the Effective Date, whose election, or nomination for election, by a majority of those individuals who are members of the board of directors and who were also members of the Incumbent Board (or deemed to be such pursuant to this proviso) sha ll be considered as though such individual were a member of the Incumbent Board; and, provided further, however, that any such individual whose initial assumption of office occurs as the result of or in connection with either an actual or threatened election contest (as such terms are used in Rule 14a-11 or Regulation 14A of the Act) or other actual or threatened solicitation of proxies or consents by or on behalf of an entity other than the board of directors shall not be so considered as a member of the Incumbent Board.

(5)

Represents the lesser of the target annual incentive for the year in which termination occurs and the average of the bonus received by Mr. O’Kane for the previous three years ($491,600) plus twice the sum of the highest salary paid during the term of the agreement ($737,400) and the average bonus actually earned during three years immediately prior to termination ($491,600). Mr. O’Kane’s agreement includes provisions with respect the treatment of ‘‘parachute payments’’ under the U.S. Internal Revenue Code. As Mr. O’Kane is currently not a U.S. taxpayer, the above amounts do not reflect the impact of such provisions.

(6)

Represents the acceleration of vesting of the unearned portion of the 2003 options, the 2004 performance shares and the entire grant of the 2006 options and 2006 performance shares. With respect to options, the value is based on the difference between the exercise price and the closing price of our shares on December 29, 2006 of $26.36. With respect to performance shares, the value is based on the closing price of our shares on December 29, 2006. The amounts do not include the (i) 2005 options, as the performance targets were not met and the options were forfeited, (ii) 2005 performance share awards, as one-third of the grant based on a one-year 2005 ROE target has not been met and was therefore forfeited, and it is unlikely that two-thirds of the grant based on an average 2005-2007 ROE wi ll be met and (iii) 2004 options, as the unearned portion vested as at December 31, 2006, and any remaining unearned portions of the grant were forfeited due to non-achievement of performance targets.

(7)

Represents the lesser of the target annual incentive for the year in which termination occurs and the average of the bonus received by Mr. Cusack for the previous three years ($231,833) plus twice the sum of the highest salary paid during the term of the agreement ($455,305) and the average bonus actually earned during three years immediately prior to termination ($231,833).

(8)

Represents the acceleration of vesting of the unearned portion of the 2003 options and the entire grant of 2006 options and 2006 performance shares. With respect to options, the value is based on the difference between the exercise price and the closing price of our shares on December 29, 2006 of $26.36.

The amounts do not include the (i) 2005 options, as the performance targets were not met and the options were forfeited, (ii) 2005 performance share awards, as one-third of the grant based on a one-year 2005 ROE target has not been met and was therefore forfeited, and it is unlikely that two-thirds of the grant based on an average 2005-2007 ROE will be met and (iii) 2004 options, as the unearned portion vested as at December 31, 2006, and any remaining unearned portions of the grant were forfeited due to non-achievement of performance targets.


(9)	Represents Mr. Sinclair’s guaranteed 2006 bonus ($387,135), as Mr. Sinclair was hired in 2006 and therefore an average bonus over a three-year period is not applicable, plus the sum of the highest salary paid during the term of the agreement ($691,313).

(10)

Represents the acceleration of vesting of the unearned portion of Mr. Sinclair’s restricted share units granted in 2006 and the entire grant of 2006 options and 2006 performance shares. With respect to options, the value is based on the difference between the exercise price and the closing price of our shares on December 29, 2006 of $26.36.

Summary of Non-Employee Director Compensation

Annual Fees. The compensation of non-executive directors is benchmarked against comparable companies, taking into account complexity, time commitment and committee duties. With effect from July 1, 2005, members of our board of directors who are not otherwise affiliated with the Company as employees or officers were paid an annual fee of $70,000. The chairman of each committee of our board of directors other than the Audit Committee received an additional $5,000 per annum and the Audit Committee chairman received an additional $25,000 per annum. Other members of the Audit Committee also will receive an additional $10,000 per annum for service on that Committee. Mr. Myners received an annual salary of £126,000 and a bonus of £150,000 for 2006 for serving as Chairman of our board of directors. Mr. Myners’ annual salary for 2007 will be £150,000.

Non-Employee Directors Stock Option Plan. At our annual general meeting of shareholders held on May 25, 2006, our shareholders approved the 2006 Stock Option Plan under which a total of 400,000 ordinary shares may be issued in relation to options granted under the 2006 Stock Option Plan.

Following the annual general meeting of our shareholders, on May 25, 2006, our board of directors approved the grant of 4,435 options under the 2006 Stock Option Plan for each of the non-employee directors, other than Mr. Myners, our Chairman. With respect to the options granted to Mr. Melwani and Mr. Salame, the options were issued in the name of Blackstone and Credit Suisse, respectively, their employers, and through which they were originally appointed to the board of directors. Eighty percent of the options granted to Ms. Hutter were issued to The Black Diamond Group LLC, of which she is the Chief Executive Officer. Messrs. Cavoores and Jones were not members of the board of directors at the time of grant, and therefore did not receive any options. The exercise price is $21.96, the average of the high and low prices of the Company’s ordinary shares on the date of grant (May 25, 2006). Subject to the grantee’s continued service as a director, the options will vest on the third anniversary of the grant date.

Compensation Committee Interlocks and Insider Participation

Mr. Melwani is a member of our Compensation Committee. During 2006, we invested approximately $75 million of our assets in funds of hedge funds with an affiliate of Blackstone, one of our principal shareholders. Mr. Melwani, a non-executive director of the Company, is a Senior Managing Director of Blackstone’s Private Equity Group. Mr. Melwani has no financial interest in the investment. In 2007, we made further investments in funds of hedge funds affiliated with Blackstone in the amount of $150 million. The investment was approved by the Investment Committee without the participation of Mr. Melwani.

Narrative Description of Summary Compensation and Grants of Plan-Based Awards

Share Incentive Plan

We have adopted the Aspen Insurance Holdings Limited 2003 Share Incentive Plan, as amended (‘‘2003 Share Incentive Plan’’) to aid us in recruiting and retaining key employees and directors and to

motivate such employees and directors. The 2003 Share Incentive Plan was amended at our Annual General Meeting in 2005 to increase the number of shares that can be issued under the plan. The total number of ordinary shares that may be issued under the 2003 Share Incentive Plan is 9,476,553.

The plan provides for the grant to selected employees and non-employee directors of share options, share appreciation rights, restricted shares and other share-based awards. The shares subject to initial grant of options (the ‘‘initial grant options’’) represented an aggregate of 5.75% of our ordinary shares on a fully diluted basis (3,884,030 shares), assuming the exercise of all outstanding options issued to Wellington and the Names’ Trustee. In addition, an aggregate of 2.5% of our ordinary shares on a fully diluted basis (1,840,540 shares), were reserved for additional grant or issuance of share options, share appreciation rights, restricted shares and/or other share-based awards as and when deter mined in the sole discretion of our board of directors or the Compensation Committee. No award may be granted under the plan after the tenth anniversary of its effective date. The plan provides for equitable adjustment of affected terms of the plan and outstanding awards in the event of any change in the outstanding ordinary shares by reason of any share dividend or split, reorganization, recapitalization, merger, consolidation, spin-off, combination, combination or transaction or exchange of shares or other corporate exchange, or any distribution to Shareholders of shares other than regular cash dividends or any similar transaction. In the event of a change in control (as defined in the plan), our board of directors or the Compensation Committee may accelerate, vest or cause the restrictions to lapse with respect to, all or any portion of an award (except that shares subject to the initial grant options shall vest); or cancel awards for fair value; or provide for the issuance of substitute awards that subst antially preserve the terms of any affected awards; or provide that for a period of at least 15 days prior to the change in control share options will be exercisable and that upon the occurrence of the change in control, such options shall terminate and be of no further force and effect.

Initial Options. The initial grant options have a term of ten years and an exercise price of $16.20 per share, which price was calculated based on 109% of the calculated fair market value of our ordinary shares as of May 29, 2003 and was determined by an independent consultant. Sixty-five percent of the initial grant options are subject to time-based vesting with 20% vesting upon grant and 20% vesting on each December 31 of calendar years 2003, 2004, 2005 and 2006. The remaining 35% of the initial grant options are subject to performance-based vesting determined by achievement of return on equity targets, and subject to achieving a threshold combined ratio target, in each case, over the applicable one or two-year performance period. Initial grant options that do not vest based on the applicable performance targets may vest in later years to the extent performance in such years exceeds 100% of the applicable targets, and i n any event, any unvested and outstanding performance-based initial grant options will become vested on December 31, 2009. Upon termination of a participant’s employment, any unvested options shall be forfeited, except that if the termination is due to death or disability (as defined in the option agreement), the time-based portion of the initial grant options shall vest to the extent such option would have otherwise become vested within 12 months immediately succeeding such termination due to death or disability. Upon termination of employment, vested initial grant options will be exercisable, subject to expiration of the options, until (i) the first anniversary of termination due to death or disability or, for nine members of senior management, without cause or for good reason (as those terms are defined in the option agreement), (ii) six months following termination without cause or for good reason for all other participants, (iii) three months following termination by the participant for any reas on other than those stated in (i) or (ii) above or (iv) the date of termination for cause. As provided in the plan, in the event of a change in control unvested and outstanding initial grant options shall immediately become fully vested. As at December 31, 2006, 82.23% of the initial options vested. The remaining outstanding amount of the initial options will vest on December 31, 2009.

The initial grant options may be exercised by payment in cash or its equivalent, in ordinary shares, in a combination of cash and ordinary shares, or by broker-assisted cashless exercise. The initial grant options are not transferable by a participant during his or her lifetime other than to family members, family trusts, and family partnerships.

2004 Options. In 2004, we granted a total of 500,113 nonqualified stock options to various officers of the Company. Each nonqualified stock option represents the right and option to purchase, on the terms and conditions set forth in the agreement evidencing the grant, ordinary shares of the Company, par value 0.15144558 cent per share. The exercise price of the shares subject to the option is $24.44 per share, which as determined by the 2003 Share Incentive Plan is based on the arithmetic mean of the high and low prices of the ordinary shares on the grant date as reported by the NYSE.

The options will vest over a multi-year period, with one-third ( 1/3) of the shares underlying the options vesting upon the later of (i) the date the Company’s outside auditors complete the audit of the Company’s financial statements containing the information necessary to compute its return on equity (‘‘ROE’’) for the fiscal year ended December 31, 2004, or (ii) the date such ROE is approved by the board of directors or an authorized committee thereof (the ‘‘Initial Vesting’’), but only if the Company achieves its ROE target for the fiscal year ended December 31, 2004 (i.e., the fiscal year in which the options are granted). If the Company fails to reach the ROE targ et for the 2004 fiscal year, but its actual ROE for such year is not less than 66.67% of the target ROE, then a reduced number of shares underlying options will vest over such multi-year period based on the percentage of target ROE achieved, for example, with 10% vesting at 66.67% (the ‘‘Reduced Percentage’’). A further one-third ( 1/3) of the shares (or one-third of the Reduced Percentage, as applicable) underlying the options will vest upon each of the first and second anniversaries of the Initial Vesting based on the achievement of the ROE target for the 2004 fiscal year consistent with the terms of the Initial Vesting described above. However, no options will vest if the ROE for the 2004 fiscal year is less than (i) 66.67% of the target ROE for such year or (ii) 10% in absolute terms. Of the total grant of 2004 options, 51.48% have vested as at December 31, 2006. The remaining amounts have been forfeited due to the performance targets not being met.

If an optionee’s employment with the Company is terminated for any reason, the Company will cancel the unvested portion of the option without consideration and the vested portion will remain exercisable for the period described in the following paragraph; provided that if an optionee’s employment is terminated by the Company for cause (as defined in the option agreement), the vested portion of the option will immediately be cancelled without consideration.

Optionees may exercise all or any part of the vested portion of their option at any time prior to the earliest to occur of (i) the tenth anniversary of the date of grant, (ii) the first anniversary of the optionee’s termination of employment (x) due to death or disability (as defined in the option agreement), (y) by the Company without cause, or (z) by the optionee with good reason (as defined in the option agreement), (iii) three months following the date of the optionee’s termination of employment by the optionee without good reason, or (iv) the date of the optionee’s termination of employment by the Company for cause. Options are exercised by providing written notice specifying the number of shares for which t he option is being exercised and the method of payment of the exercise price. Payment of the exercise price may be made in cash (or cash equivalent), in shares, in a combination of cash and shares, or by broker-assisted cashless exercise. The optionee may be required to pay to the Company, and the Company will have the right to withhold, any applicable withholding taxes in respect of the option, its exercise or any payment or transfer under or with respect to the option.

2005 Options. On March 3, 2005, we granted an aggregate of 512,172 nonqualified stock options. The exercise price of the shares subject to the option is $25.88 per share, which as determined by the plan is based on the arithmetic mean of the high and low prices of the ordinary shares on the grant date as reported by the NYSE. We also granted an additional 13,709 nonqualified stock options during 2005, the exercise price of those shares varied from $25.28 to $26.46. The ROE target was not met in 2005, and as a result, all granted options have been forfeited.

2006 Options. On February 16, 2006, we granted an aggregate of 1,079,437 nonqualified stock options. The exercise price of the shares subject to the option is $23.65 per share, which as determined by the plan is based on the arithmetic mean of the high and low prices of the ordinary shares on February 17, 2006 as reported by the NYSE. We granted an additional 142,158 options on August 4, 2006, for an exercise price of $23.19.

One-third ( 1/3) of the shares underlying the options will become eligible for vesting upon the later of (i) the date the Company’s outside auditors complete the audit of the Company’s financial statements containing the information necessary to compute its ROE for the fiscal year ended December 31, 2006, or (ii) the date such ROE is approved by the board of directors or an authorized committee thereof, but only if the Company achieves its ROE target for the fiscal year ended December 31, 2006 (the ‘‘2006 Option Award’’). If the Company fails to reach the ROE target for the 2006 fiscal year, but its actual ROE for such year is not less than 66.67% of the target ROE, then a reduced number of options will become eligible for vesting based on the percentage of target ROE achieved, for example, with 10% vesting at 66.67%. However, no options will become eligible for vesting for the 2006 Option Award if the ROE for the 2006 fiscal year is less than (i) 66.67% of the target ROE for such year or (ii) 10% in absolute terms. As the ROE target was achieved in 2006, one-third of the options granted are eligible for vesting.

Two-thirds ( 2/3) of the options will become eligible for vesting upon the later of (i) the date the Company’s outside auditors complete the audit of the Company’s financial statements containing the information necessary to compute its ROE for the fiscal year ended December 31, 2008, or (ii) the date such ROE is approved by the board of directors or an authorized committee thereof, but only if the Company’s actual average annual ROE for the 2006, 2007 and 2008 fiscal years meets or exceeds the average annual ROE target for such period (the ‘‘2006-2008 Option Award’’). If the Company fails to achieve the average annual ROE target for the 2006, 2007 and 2008 fiscal years, but its actual a verage ROE for such period is not less than 66.67% of the average annual ROE target, then a reduced number of options will become eligible for vesting based on the percentage of the average annual ROE target achieved, for example, with 10% being eligible for vesting at 66.67%. However, no options will be eligible for vesting for the 2006-2008 Option Award if the actual average annual ROE for the 2006, 2007 and 2008 fiscal years is less than (i) 66.67% of the average annual ROE target for such period or (ii) 10% in absolute terms.

Options which are eligible for vesting, as described above, as part of the 2006 Option Award and the 2006-2008 Option Award will vest and become exercisable upon the later of (i) the date the Company’s outside auditors complete the audit of the Company’s financial statements containing the information necessary to compute its ROE for the fiscal year ended December 31, 2008, or (ii) the date such 2008 ROE is approved by the board of directors or an authorized committee thereof, subject to the optionee’s continued employment (and lack of notice of resignation or termination) until such date.

Once the options are exercisable, as described above, the optionee may exercise all or any part of the vested portion of their option at any time prior to the earliest to occur of (i) the tenth anniversary of the date of grant, (ii) the first anniversary of the optionee’s termination of employment (x) due to death or disability (as defined in the option agreement), (y) by the Company without cause (as defined in the option agreement), or (z) by the optionee with good reason (as defined in the option agreement), (iii) three months following the date of the optionee’s termination of employment by the optionee without good reason, or (iv) the date of the optionee’s termination of employment by the Company for cause.

Options are exercised by providing written notice specifying the number of shares for which the option is being exercised and the method of payment of the exercise price. Payment of the exercise price may be made in cash (or cash equivalent), in shares, in a combination of cash and shares, or by broker-assisted cashless exercise. The optionee may be required to pay to the Company, and the Company will have the right to withhold, any applicable withholding taxes in respect of the option, its exercise or any payment or transfer under or with respect to the option. Options may not be assigned, sold or otherwise transferred by the optionee other than by will or by the laws of descent and distribution.

Restricted Share Units. In 2004, we granted 95,850 restricted share units to various employees of the Company and its subsidiaries which vest in one-third tranches over three years. In 2005, we granted 48,913 restricted shares units which vest in one-third tranches over three years. In 2006, we granted 164,932 restricted shares units which vest in one-third tranches over three years. Vesting of a

participant’s units may be accelerated, however, if the participant’s employment with the Company and its subsidiaries is terminated without cause (as defined in such participant’s award agreement), on account of the participant’s death or disability (as defined in such participants award agreement), or, with respect to some of the participants, by the participant with good reason (as defined in such participant’s award agreement). Participants will be paid one ordinary share for each unit that vests as soon as practicable following the vesting date.

Recipients of the restricted share units generally will not be entitled to any rights of a holder of ordinary shares, including the right to vote, unless and until their units vest and ordinary shares are issued; provided, however, that participants will be entitled to receive dividend equivalents with respect to their units. Dividend equivalents will be denominated in cash and paid in cash if and when the underlying units vest. Participants may, however, be permitted by the Company to elect to defer the receipt of any ordinary shares upon the vesting of units, in which case payment will not be made until such time or times as the participant may elect. Payment of deferred share units would be in ordinary shares with any cash divi dend equivalents credited with respect to such deferred share units paid in cash.

2004 Performance Share Awards. On December 22, 2004, we granted an aggregate of 150,074 performance share awards to various officers of the Company. Each performance share award represents the right to receive, on the terms and conditions set forth in the agreement evidencing the award, a specified number of ordinary shares of the Company, par value 0.15144558 cent per share. Payment of performance shares is contingent upon the achievement of specified ROE targets.

One-third ( 1/3) of the performance shares will become vested upon the later of (i) the date the Company’s outside auditors complete the audit of the Company’s financial statements containing the information necessary to compute its ROE for the fiscal year ended December 31, 2004, or (ii) the date such ROE is approved by the board of directors or an authorized committee thereof, but only if the Company achieves its ROE target for the fiscal year ended December 31, 2004 (the ‘‘2004 Award’’). If the Company fails to reach the ROE target for the 2004 fiscal year, but its actual ROE for such year is not less than 66.67% of the target ROE, then a reduced number of performance shares will vest bas ed on the percentage of target ROE achieved, for example, with 10% vesting at 66.67%. However, no performance shares will vest for the 2004 Award if the ROE for the 2004 fiscal year is less than (i) 66.67% of the target ROE for such year or (ii) 10% in absolute terms.

Two-thirds ( 2/3) of the performance shares will become vested and payable upon the later of (i) the date the Company’s outside auditors complete the audit of the Company’s financial statements containing the information necessary to compute its ROE for the fiscal year ended December 31, 2006, or (ii) the date such ROE is approved by the board of directors or an authorized committee thereof, but only if the Company’s actual average annual ROE for the 2004, 2005 and 2006 fiscal years meets or exceeds the average annual ROE target for such period (the ‘‘2004-2006 Award’’). If the Company fails to achieve the average annual ROE target for the 2004, 2005 and 2006 fiscal years, but its actua l average ROE for such period is not less than 66.67% of the average annual ROE target, then a reduced number of performance shares will be paid to the participants based on the percentage of the average annual ROE target achieved, for example, with 10% awarded at 66.67%. With respect to the 2004 performance share awards, 17.16% of the total grant has vested. However, no performance shares will vest for the 2004-2006 Award if the actual average annual ROE for the 2004, 2005 and 2006 fiscal years is less than (i) 66.67% of the average annual ROE target for such period or (ii) 10% in absolute terms. The remainder of the 2004 performance share grants is forfeited due to the non-achievement of performance targets. Of the total grant of 2004 performance share awards, 17.16% will vest and be issuable in the first quarter of 2007. The remaining amounts of the grant have been forfeited due to the performance targets not being met.

Payment of vested performance shares as part of the 2004 Award shall be paid at the same time as the performance shares part of the 2004-2006 Award are paid (or would have been paid had all or a portion of the 2004-2006 Award vested), subject to the participant’s continued employment (and lack of notice of resignation or termination) until such payment date. Payment of vested performance shares as part of the 2004-2006 Award generally will occur as soon as practicable after the date the

performance shares become vested, subject to the participant’s continued employment (and lack of notice of resignation or termination) until such payment date. Participants may be required to pay to the Company, and the Company will have the right to withhold, any applicable withholding taxes in respect of the performance shares. Performance shares may not be assigned, sold or otherwise transferred by participants other than by will or by the laws of descent and distribution.

2005 Performance Share Awards. On March 3, 2005, we granted an aggregate of 123,002 performance share awards to various officers and other employees pursuant to the 2003 Share Incentive Plan, and an additional 8,225 performance share awards were granted in 2005. Each performance share award represents the right to receive, on the terms and conditions set forth in the agreement evidencing the award, a specified number of ordinary shares of the Company, par value 0.15144558 cent per share. Payment of performance shares is contingent upon the achievement of specified ROE targets.

One-third ( 1/3) of the performance shares will become vested upon the later of (i) the date the Company’s outside auditors complete the audit of the Company’s financial statements containing the information necessary to compute its ROE for the fiscal year ended December 31, 2005, or (ii) the date such ROE is approved by the board of directors or an authorized committee thereof, but only if the Company achieves its ROE target for the fiscal year ended December 31, 2005 (the ‘‘2005 Award’’). If the Company fails to reach the ROE target for the 2005 fiscal year, but its actual ROE for such year is not less than 66.67% of the target ROE, then a reduced number of performance shares will vest bas ed on the percentage of target ROE achieved, for example, with 10% vesting at 66.67%. However, no performance shares will vest for the 2005 Award if the ROE for the 2005 fiscal year is less than (i) 66.67% of the target ROE for such year or (ii) 10% in absolute terms. The 2005 ROE target was not met, therefore one-third of the grant has been forfeited.

Two-thirds ( 2/3) of the performance shares will become vested and payable upon the later of (i) the date the Company’s outside auditors complete the audit of the Company’s financial statements containing the information necessary to compute its ROE for the fiscal year ended December 31, 2007, or (ii) the date such ROE is approved by the board of directors or an authorized committee thereof, but only if the Company’s actual average annual ROE for the 2005, 2006 and 2007 fiscal years meets or exceeds the average annual ROE target for such period (the ‘‘2005-2007 Award’’). If the Company fails to achieve the average annual ROE target for the 2005, 2006 and 2007 fiscal years, but its actua l average ROE for such period is not less than 66.67% of the average annual ROE target, then a reduced number of performance shares will be paid to the participants based on the percentage of the average annual ROE target achieved, for example, with 10% awarded at 66.67%. However, no performance shares will vest for the 2005-2007 Award if the actual average annual ROE for the 2005, 2006 and 2007 fiscal years is less than (i) 66.67% of the average annual ROE target for such period or (ii) 10% in absolute terms. It is unlikely that the remaining two-thirds of the grant of the 2005 performance share awards will be eligible for vesting due to our losses in 2005.

Payment of vested performance shares as part of the 2005 Award shall be paid at the same time as the performance shares part of the 2005-2007 Award are paid (or would have been paid had all or a portion of the 2005-2007 Award vested), subject to the participant’s continued employment (and lack of notice of resignation or termination) until such payment date. Payment of vested performance shares as part of the 2005-2007 Award generally will occur as soon as practicable after the date the performance shares become vested, subject to the participant’s continued employment (and lack of notice of resignation or termination) until such payment date. Participants may be required to pay to the Company, and the Company will hav e the right to withhold, any applicable withholding taxes in respect of the performance shares. Performance shares may not be assigned, sold or otherwise transferred by participants other than by will or by the laws of descent and distribution.

2006 Performance Share Awards. On February 16, 2006, we granted an aggregate of 324,465 performance share awards to various officers and other employees pursuant to the 2003 Share Incentive Plan. We granted an additional 1,042 performance share awards on August 4, 2006. Each performance share award represents the right to receive, on the terms and conditions set forth in the

agreement evidencing the award, a specified number of ordinary shares of the Company, par value 0.15144558 cent per share. Payment of performance shares is contingent upon the achievement of specified ROE targets.

One-third ( 1/3) of the performance shares will become eligible for vesting upon the later of (i) the date the Company’s outside auditors complete the audit of the Company’s financial statements containing the information necessary to compute its ROE for the fiscal year ended December 31, 2006, or (ii) the date such ROE is approved by the board of directors or an authorized committee thereof, but only if the Company achieves its ROE target for the fiscal year ended December 31, 2006 (the ‘‘2006 Performance Award’’). If the Company fails to reach the ROE target for the 2006 fiscal year, but its actual ROE for such year is not less than 66.67% of the target ROE, then a reduced number of perfor mance shares will become eligible for vesting based on the percentage of target ROE achieved, for example, with 10% becoming eligible for vesting at 66.67%. However, no performance shares will become eligible for vesting for the 2006 Performance Award if the ROE for the 2006 fiscal year is less than (i) 66.67% of the target ROE for such year or (ii) 10% in absolute terms. One-third of the grant based on the ROE target for 2006 is available for vesting as the 2006 ROE target was achieved.

Two-thirds ( 2/3) of the performance shares will become eligible for vesting and payable upon the later of (i) the date the Company’s outside auditors complete the audit of the Company’s financial statements containing the information necessary to compute its ROE for the fiscal year ended December 31, 2008, or (ii) the date such ROE is approved by the board of directors or an authorized committee thereof, but only if the Company’s actual average annual ROE for the 2006, 2007 and 2008 fiscal years meets or exceeds the average annual ROE target for such period (the ‘‘2006-2008 Performance Award’’). If the Company fails to achieve the average annual ROE target for the 2006, 2007 and 2008 fi scal years, but its actual average ROE for such period is not less than 66.67% of the average annual ROE target, then a reduced number of performance shares will become eligible for vesting based on the percentage of the average annual ROE target achieved, for example, with 10% becoming eligible for vesting at 66.67%. However, no performance shares will be eligible for vesting for the 2006-2008 Performance Award if the actual average annual ROE for the 2006, 2007 and 2008 fiscal years is less than (i) 66.67% of the average annual ROE target for such period or (ii) 10% in absolute terms.

Performance shares which are eligible for vesting, as described above, as part of the 2006 Performance Award and the 2006-2008 Performance Award will vest upon the later of (i) the date the Company’s outside auditors complete the audit of the Company’s financial statements containing the information necessary to compute its ROE for the fiscal year ended December 31, 2008, or (ii) the date such 2008 ROE is approved by the board of directors or an authorized committee thereof, subject to the participant’s continued employment (and lack of notice of resignation or termination) until such date.

Payment of vested performance shares will occur as soon as practicable after the date the performance shares become vested. Participants may be required to pay to the Company, and the Company will have the right to withhold, any applicable withholding taxes in respect of the performance shares. Performance shares may not be assigned, sold or otherwise transferred by participants other than by will or by the laws of descent and distribution.

POLICY ON SHAREHOLDER PROPOSALS FOR DIRECTOR
CANDIDATES AND EVALUATION OF DIRECTOR CANDIDATES

Our board of directors has adopted policies and procedures relating to director nominations and shareholder proposals, and evaluations of director candidates.

Submission of Shareholder Proposals. Shareholder recommendations of director nominees to be included in the Company’s proxy materials will be considered only if received no later than the 120th calendar day before the first anniversary of the date of the Company’s proxy statement in connection with the previous year’s Annual General Meeting. The Company may in its discretion exclude such shareholder recommendations even if received in a timely manner. Accordingly, this policy is not intended to waive the Company’s right to exclude shareholder proposals from its proxy statement.

If Shareholders wish to nominate their own candidates for director on their own separate slate (as opposed to recommending candidates to be nominated by the Company in the Company’s proxy), shareholder nominations for directors at the Annual General Meeting of Shareholders must be submitted at least 90 calendar days before the Annual General Meeting of Shareholders.

A shareholder who wishes to recommend a person or persons for consideration as a Company nominee for election to the board of directors should send a written notice by mail, c/o Company Secretary, Aspen Insurance Holdings Limited, Maxwell Roberts Building, 1 Church Street, Hamilton HM11, Bermuda, or by fax to 1-441-295-1829 and include the following information:


	•	the name of each person recommended by the shareholder(s) to be considered as a nominee;


	•	the name(s) and address(es) of the shareholder(s) making the nomination, the number of ordinary shares which are owned beneficially and of record by such shareholder(s) and the period for which such common shares have been held;


	•	a description of the relationship between the nominating shareholder(s) and each nominee;


	•	biographical information regarding such nominee, including the person’s employment and other relevant experience and a statement as to the qualifications of the nominee;


	•	a business address and telephone number for each nominee (an e-mail address may also be included); and


	•	the written consent to nomination and to serving as a director, if elected, of the recommended nominee.

In connection with the Corporate Governance and Nominating Committee’s evaluation of director nominees, the Company may request that the nominee complete a Directors and Officers Questionnaire regarding such nominee’s independence, related parties transactions, and other relevant information required to be disclosed by the Company.

Minimum Qualifications for Director Nominees. A nominee recommended for a position on the Company’s board of directors must meet the following minimum qualifications:


	•	he or she must have the highest standards of personal and professional integrity;


	•	he or she must have exhibited mature judgment through significant accomplishments in their chosen field of expertise;


	•	he or she must have a well-developed career history with specializations and skills that are relevant to understanding and benefiting the Company;


	•	he or she must be able to allocate sufficient time and energy to director duties, including preparation for meetings and attendance at meetings;


	•	he or she must be able to read and understand basic financial statements; and


	•	he or she must be familiar with, and willing to assume, the duties of a director on the board of directors of a public company.

Process for Evaluation of Director Nominees. The Corporate Governance and Nominating Committee has the authority and responsibility to lead the search for individuals qualified to become

members of our board of directors to the extent necessary to fill vacancies on the board of directors or as otherwise desired by the board of directors. The Corporate Governance and Nominating Committee will identify, evaluate and recommend that the board of directors select director nominees for shareholder approval at the applicable annual meetings based on minimum qualifications and additional criteria that the Corporate Governance and Nominating Committee deems necessary, as well as the diversity and other needs of the board of directors.

The Corporate Governance and Nominating Committee may in its discretion engage a third-party search firm and other advisors to identify potential nominees for director. The Corporate Governance and Nominating Committee may also identify potential director nominees through director and management recommendations, business, insurance industry and other contacts, as well as through shareholder nominations.

The Corporate Governance and Nominating Committee may determine that members of the board of directors should have diverse experiences, skills and perspectives as well as knowledge in the areas of the Company’s activities.

Certain additional criteria for consideration as director nominee may include, but not be limited to, the following as the Corporate Governance and Nominating Committee sees fit:


	•	the nominee’s qualifications and accomplishments and whether they complement the board of directors’ existing strengths;


	•	the nominee’s leadership, strategic, or policy setting experience;


	•	the nominee’s experience and expertise relevant to the Company’s insurance and reinsurance business, including any actuarial or underwriting expertise, or other specialized skills;


	•	the nominee’s independence qualifications, as defined by NYSE listing standards;


	•	the nominee’s actual or potential conflict of interest, or the appearance of any conflict of interest, with the best interests of the Company and its Shareholders;


	•	the nominee’s ability to represent the interests of all Shareholders of the Company; and


	•	the nominee’s financial literacy, accounting or related financial management expertise as defined by NYSE listing standards, or qualifications as an audit committee financial expert, as defined by SEC rules and regulations.

Shareholder Communications to the Board of Directors

AMENDMENT TO 2006 NON-EMPLOYEE DIRECTOR STOCK OPTION PLAN

(Proposal No. 4)

Proposal No. 4 calls for a vote FOR the amendment to the Company’s 2006 Stock Option Plan for non-employee directors. The Board determined at its meeting held on March 21, 2007 that it is in the best interests of the Company and its shareholders to amend the 2006 Stock Option Plan to allow the issuance of restricted share units and to rename the Plan the 2006 Stock Incentive Plan for Non-Employee Directors (the ‘‘Amended 2006 Stock Option Plan’’).

The full text of the Amended 2006 Stock Option Plan is attached to this Proxy Statement as Appendix I. The following summary of the Amended 2006 Stock Option Plan is qualified in its entirety by the provisions of such text.

General. Our Board approved the Amended 2006 Stock Option Plan on March 21, 2007, subject to shareholder approval. The 2006 Stock Option Plan is intended to benefit our shareholders by assisting the Company in recruiting and retaining the services of non-employee directors and motivating such non-employee directors through the granting of share-based incentive awards. The shares delivered under the 2006 Stock Option Plan are our ordinary shares. The shares may be shares that have been authorized but not yet issued or shares we previously issued and have reacquired. Additional information about the 2006 Stock Option Plan follows.

Purpose. The Amended 2006 Stock Option Plan provides for the granting of options (the ‘‘Options’’) and restricted stock units (‘‘RSUs’’) to non-employee directors of the Company and its affiliates (such Options and RSUs collectively referred to as ‘‘Awards’’).

Administration. The Amended 2006 Stock Option Plan may be administered by our Board or by a committee of our Board consisting solely of at least two individuals who, if Section 16 of the Securities Exchange Act of 1934, as amended (the ‘‘Exchange Act’’), is applicable, qualify as ‘‘Non-Employee Directors’’ under Exchange Act Rule 16b-3, as determined by our Board. References herein to the ‘‘Committee’’ are to the Board or such committee, as the case may be, in its capacity as Amended 2006 Stock Option Plan administrator. The Committee interprets the 2006 Stock Option Plan, establishes rules and regulations for the 2006 Stock Option Plan’s administration, determines who will receive Options and establishes the terms of the Options.

Share Limit. The total number of shares that may be issued under the Amended 2006 Stock Option Plan is 400,000. The issuance of shares or the payment of cash upon the exercise of an Option or in consideration of the cancellation or termination of an Option shall reduce the total number of shares that may be issued under the Amended 2006 Stock Option Plan. Shares that are subject to Awards that are forfeited, cancelled, expire, terminate or lapse without payment of consideration will not reduce the total number of shares that may be issued under the Amended 2006 Stock Option Plan. In the event of any share split, share dividend, reorganization, recapitalization, merger, consolidation, spin-off or other such change in our capitalization, the Committee has the discretion to make adjustments to (i) the number or kind of shares authorized for issuance or covered by outstanding Awards, (ii) the exercise price of options, (iii) the maximum number of shares for which Awards may be granted in any calendar year and/or (iv) any other affected terms of such Awards in order to prevent dilution or enlargement of benefits.

Change in Control. In the event of a change in control, the Committee may, but shall not be obligated to, (A) with respect to any Award, accelerate or vest with respect to, all or any portion of an Award or (B) cancel Awards for fair value (as reasonably determined in the discretion of the Committee) which, in the case of Options, may equal, but in any event shall not be less than, the excess, if any, of value of the consideration to be paid in the change in control transaction to holders of the same number of the Company’s ordinary shares subject to such Options (or, if no consideration is paid in any such transaction, the fair market value of the Company’s ordinary shares subject to such Options) over the aggregate exercise price of such Options or (C) provide for the issuance of substitute Awards that will substantially preserve the otherwise applicable terms of any affected Awards previously granted hereunder as determined by the Committee in its sole discretion or

(D) provide that for a period of at least 15 days prior to the change in control, Options shall be exercisable as to all of the Company’s ordinary shares subject thereto and that upon the occurrence of the change in control, such Options shall terminate and be of no further force and effect.

Limitation on Transferability of Awards. Except as otherwise provided in an award agreement or by the Committee, Awards may not be transferred or assigned other than (a) by will or the laws of descent and distribution and (b) if permitted by the Committee in its sole discretion, an Award may be granted directly or transferred to the employer of a non-employee director if such non-employee director is obligated to transfer any compensation received as a non-employee director to his or her employer. Options exercisable after the death of Options recipients may be exercised by their legatees, personal representatives or distributees.

Resale Restrictions. The ordinary shares that may be issued under the Amended 2006 Stock Option Plan may not be resold except in compliance with the terms, conditions and restrictions set forth in our bye-laws and applicable securities laws. Shares acquired pursuant to the Amended 2006 Stock Option Plan by one of our ‘‘affiliates,’’ as that term is defined in Rule 405 of the Securities Act of 1933, as amended (the ‘‘Securities Act’’), may be resold only pursuant to the registration requirements of that act or an applicable exemption therefrom. In addition, acquisitions and dispositions of our ordinary shares or derivative securities by persons subject to Section 16 of the Exchange Act within any period of less than six months, may permit us to recapture any profit from such transactions pursuant to Section 16(b) of that act. Although Section 16 does not apply as of the date of t his proxy statement, it may apply in the future and would apply if the Company no longer qualifies as a ‘‘foreign private issuer’’ under the U.S. securities laws.

Expiration, Amendment and Termination of the Plan and Awards. No Awards may be granted under the Amended 2006 Stock Option Plan after April 9, 2016. Our Board or the Committee may amend or terminate the Amended 2006 Stock Option Plan at any time, except under certain circumstances where shareholder approval would be required for any amendment that would increase the number of shares that may be delivered under the Amended 2006 Stock Option Plan or that would permit the reduction of the exercise price of Options (except for reductions in connection with anti-dilution adjustments made in connection with stock splits, reorganizations or similar events, as described above). The Amended 2006 Stock Option Plan also gives the Committee the authority to waive the terms and conditions of outstanding Awards; provided, however, that the Award recipients’ consent is required of any amendment that would adversely affect the Award recipients’ rights under an outstanding Award.

Certain U.S. Federal Income Tax Consequences. The following is a brief description of the U.S. federal income tax consequences of the Amended 2006 Stock Option Plan and Options and RSUs that may be granted under the Amended 2006 Stock Option Plan. It assumes that Options and RSU recipient are U.S. citizens or are resident in the U.S. For purposes of this section, (i) ‘‘Affiliate’’ means any of our direct or indirect subsidiaries, (ii) a ‘‘U.S. Affiliate’’ means any Affiliate that is domiciled or has an office in the United States, and (iii) a ‘‘Foreign Affiliate’’ means any other Affiliate. In general, we and our Foreign Affiliates will not be subject to U.S. federal income tax unless we or they engage in a trade or business in the United States. We and our Foreign Affiliates, other than Aspen Re, endeavor to operate and intend to continue operating so th at we and they will not be engaged in a trade or business in the United States or have an office or fixed place of business in the United States. Our U.S. Affiliates are U.S. corporations and, consequently, are U.S. taxpayers.

This summary does not address every tax consideration. This summary is based upon current law and does not purport to be a comprehensive discussion of all the tax considerations that may be relevant with respect to the Amended 2006 Stock Option Plan.

The grant of Options and RSUs does not result in any U.S. federal income tax consequences for us or our Affiliates.

If Award recipients have been granted an Option under the Amended 2006 Stock Option Plan and they are non-employee directors of one of our U.S. Affiliates, we consider such Options recipients to be ‘‘U.S. grantees.’’ As U.S. grantees, if Options recipients recognize ordinary income from the

exercise of an Option, the U.S. Affiliate for which Options recipients perform services should be entitled to a U.S. federal income tax deduction in the amount of the ordinary income Options recipients recognized.

The U.S. Affiliate will report to the Internal Revenue Service (‘‘IRS’’) any ordinary income a U.S. grantee realizes by reason of the exercise of an Option. If Options recipients are non-employee directors of such U.S. Affiliate, no amounts will be withheld for income and employment taxes.

If Options recipients have been granted Options under the Amended 2006 Stock Option Plan but are not U.S. grantees, any income recognized will not be reported to the IRS.

If Award recipients have been granted RSUs under the Amended 2006 Stock Option Plan and they are non-employee directors of one of our U.S. Affiliates, we consider such RSU recipients to be U.S. grantees. As U.S. grantees, the RSU recipient will recognize ordinary income when the RSUs (and any associated dividend equivalents) vest, equal to the amount of cash or fair market value of the shares received (and any cash received in payment of associated dividend equivalent rights).

The U.S. Affiliate will report to the IRS any ordinary income a U.S grantee recognizes by reason of the vesting of the RSUs. If RSU recipients are non-employee directors of such U.S. Affiliate, no amounts will be withheld for income and employment taxes.

If RSU recipients have been granted RSUs under the Amended 2006 Stock Option Plan but are not a U.S. grantees, any income recognized will not be reported to the IRS.

RESOLUTIONS FOR ASPEN INSURANCE UK LIMITED (‘‘ASPEN RE’’)

(Proposals No. 6, 7 and 8)

The Company’s Bye-Law 84 provides that if the Company is required or entitled to vote at a general meeting of any Non-U.S. Subsidiary, the Board will refer the subject matter of the vote to the Shareholders of the Company in a general meeting of the Company. The Company shall cause the Company’s corporate representative or proxy to vote the Company’s shares in the Non-U.S. Subsidiary pro rata to the votes received at the general meeting of the Company, with votes for or against the directing resolution being taken, respectively, as an instruction for the Company’s corporate representative or proxy to vote the appropriate proportion of its shares for, and the appropriate proportion of its shares against, the resolution proposed by our Non-U.S. Subsidiaries.

Proposal No. 6 calls for a vote on a resolution proposed by the Company in respect of Aspen Re, an indirect wholly-owned insurance company organized under the laws of England and Wales, as an instruction for the Company’s representatives or proxies to vote FOR the election of Messrs. Paul Myners, Christopher O’Kane, Ian Cormack, Marek Gumienny, Glyn Jones, Oliver Peterken and Stuart Sinclair and Ms. Heidi Hutter as company directors to the board of directors of Aspen Re.

Biographical information relating to the directors under Proposal No. 6 is presented in this Proxy Statement under ‘‘Management — Board of Directors of the Company,’’ ‘‘— Executive Officers of the Company’’ and ‘‘— Boards of Directors of Non-U.S. Subsidiaries.’’

Proposal No. 7 calls for a vote on a resolution proposed by the Company in respect of Aspen Re as an instruction for the Company’s representatives or proxies to vote FOR:

i) in place of the authority given in Article 4(B) of Aspen Re’s articles of association, the directors of Aspen Re are generally and unconditionally authorized for the purposes of Section 80 of the United Kingdom’s Companies Act 1985 (as amended) at any time or times during the period of five years from the date of the Aspen Re Resolution to allot, or to grant any right to subscribe for, or to convert any security into, shares in the authorized share capital of Aspen Re at the date of the Aspen Re Resolution;

ii) the maximum amount of relevant securities which may be allotted pursuant to the authority conferred in (i) above is 50% of the authorized but as yet unissued share capital of Aspen Re at the date of the Aspen Re Resolution; and

iii) at the expiry of the period of five years, the authority contained in (i) above shall expire, but the directors of Aspen Re may make an offer or agreement before the expiry of the authority which would or might require shares to be allotted or rights to subscribe for or to convert any security into shares to be granted, after the expiry of the authority.

Under the provisions of Aspen Re’s articles of association, the board of directors is authorized to allot ordinary shares pursuant to Section 80 of the United Kingdom’s Companies Act 1985 (as amended). Ordinary shares under English law are similar to shares of common stock of companies domiciled in the United States. Under the United Kingdom’s Companies Act 1985 (as amended), ordinary shares may not be issued until after they have first been allotted (authorized for issuance) by the board of directors. Allotment of securities by the board of directors from Aspen Re’s authorized share capital requires the grant of a general power of allotment by Aspen Re’s shareholders, an additional step not generally required when companies domiciled in the United States are issuing securities. Such authority can be granted for a maximum period of five years. This resolution grants such authority to the directors and is intended to be renewed at each successive Annual General Meeting.

Proposal No. 8 calls for a vote on a resolution proposed by the Company in respect of Aspen Re as an instruction for the Company’s representatives or proxies to vote FOR the re-appointment of KPMG Audit Plc as the auditor of Aspen Re for the fiscal year ending December 31, 2007, to hold office from the conclusion of Aspen Re’s Annual General Meeting to the conclusion of the next Annual General Meeting of Aspen Re and to grant authority to the Company’s Board through its

	(c)	The Committee is authorized to interpret the Plan, to establish, amend and rescind any rules and regulations relating to the Plan, and to make any other determinations that it deems necessary or desirable for the administration of the Plan, and may delegate such authority, as it deems appropriate.

	(b)	Without the approval of the shareholders of the Company, the Company shall not adjust an Option or exchange an Option with another Option if it would result in an Option with a lower Option Price (except for adjustments pursuant to Section 7 of the Plan).


6.	Terms and Conditions of Options


	Options granted under the Plan shall be nonqualified stock options for United States federal income tax purposes, and shall be subject to the foregoing and the following terms and conditions and to such other terms and conditions, not inconsistent therewith, as the Committee shall determine:


	(a)	Option Price. The Option Price per Share shall be determined by the Committee, but shall not be less than 100% of the Fair Market Value of the Shares on the date an Option is granted (except to the extent the Option Price is adjusted pursuant to Section 7 of the Plan).


	(b)	Exercisability. Options granted under the Plan shall be exercisable at such time and upon such terms and conditions as may be determined by the Committee, but in no event shall an Option be exercisable more than ten years after the date it is granted, except as may be provided pursuant to Section 13.


	(c)	Exercise of Options. Except as otherwise provided in the Plan or in an Award agreement, an Option may be exercised for all, or from time to time any part, of the Shares for which it is then exercisable. For purposes of this Section 6, the exercise date of an Option shall be the date a notice of exercise is received by the Company, together with payment (or to the extent permitted by applicable law, provision for payment) of the full purchase price in accordance

I-4


		with this Section 6(c). The purchase price for the Shares as to which an Option is exercised shall be paid to the Company, as designated by the Committee, pursuant to one or more of the following methods (subject in each case to such conditions or restrictions as the Committee may prescribe): (i) in cash or its equivalent (e.g., by check); (ii) in Shares having a Fair Market Value equal to the aggregate Option Price for the Shares being purchased and satisfying such other requirements as may be imposed by the Committee; (iii) partly in cash and partly in Shares; (iv) through the delivery of irrevocable instructions to a broker to sell Shares obtained upon the exercise of the Option and to deliver promptly to the Company an amount out of the proceeds of such sale equal to the aggregate Option Price for the Shares being purchased; or (v) by such other means as the Committee may prescribe. No Participant shall have any rights to dividends or other rights of a shareholder with respect to Shares su bject to an Option until the Participant has given written notice of exercise of the Option, paid in full for such Shares and, if applicable, has satisfied any other conditions imposed by the Committee.


	(d)	Attestation. Wherever in this Plan or any agreement evidencing an Option, a Participant is permitted to pay the Option Price or taxes relating to the exercise of an Option by delivering Shares, the Participant may, subject to procedures satisfactory to the Committee, satisfy such delivery requirement by presenting proof of beneficial ownership of such Shares, in which case the Company shall treat the Option as exercised without further payment and/or shall withhold such number of Shares from the Shares acquired by the exercise of the Option, as appropriate.


7.	Terms and Conditions of Restricted Share Units


	(a)	Generally. Subject to the provisions of the Plan, the Committee shall determine the number of Restricted Share Units to be granted to a Participant, the duration of the period during which, and the conditions, if any, under which, the Restricted Share Units may be forfeited to the Company, and the other terms and conditions of such Awards. An Award of Restricted Share Units shall consist of a grant of units, each of which represents the right of the Participant to receive one Share, subject to the terms and conditions established by the Committee in connection with the Award and set forth in the applicable Award agreement. Upon satisfaction of the conditions to vesting and payment specified in the applicable Award agreement, Restricted Share Units will be payable in Shares or, if the Committee so det ermines, in cash, equal to the Fair Market Value of the Shares subject to such Restricted Share Units.


	(b)	Dividends. Dividends paid on any Restricted Share Units may be paid directly to the Participant, withheld by the Company subject to vesting of the Restricted Share Units pursuant to the terms of the applicable Award agreement, or may be reinvested in additional Restricted Share Units, as determined by the Committee in its sole discretion.


8.	Adjustments Upon Certain Events


	Notwithstanding any other provisions in the Plan to the contrary, the following provisions shall apply to all Awards granted under the Plan:


	(a)	Generally. In the event of any change in the outstanding Shares after the Effective Date by reason of any Share dividend or split, reorganization, amalgamation, recapitalization, merger, consolidation, spin-off, combination or transaction or exchange of Shares or other corporate exchange, or any distribution to shareholders of Shares other than regular cash dividends or any transaction similar to the foregoing, the Committee in its sole discretion and without liability to any person shall make such substitutions or adjustments as it deems to be equitable, in its sole discretion, and necessary to preserve the benefits or potential benefits intended to be made available under this Plan as to (i) the number or kind of Shares or other securities that may be issued pursuant to the Plan or outstanding Awar ds, (ii) the Option Price of any outstanding Option and/or (iii) any other affected terms of such Awards.

I-5


	(b)	Change in Control. In the event of a Change in Control, the Committee may, but shall not be obligated to, (A) with respect to any Award, accelerate or vest with respect to, all or any portion of an Award or (B) cancel Awards for fair value (as reasonably determined in the discretion of the Committee) which, in the case of Options, may equal, but in any event shall not be less than, the excess, if any, of value of the consideration to be paid in the Change in Control transaction to holders of the same number of Shares subject to such Options (or, if no consideration is paid in any such transaction, the Fair Market Value of the Shares subject to such Options) over the aggregate exercise price of such Options or (C) provide for the issuance of substitute Awards that will substantially preserve the other wise applicable terms of any affected Awards previously granted hereunder as determined by the Committee in its sole discretion or (D) provide that for a period of at least 15 days prior to the Change in Control, such Options shall be exercisable as to all Shares subject thereto and that upon the occurrence of the Change in Control, such Options shall terminate and be of no further force and effect.


9.	No Right to Service or Awards

The granting of an Award under the Plan shall impose no obligation on the Company or any Affiliate to continue the Service of a Participant and shall not lessen or affect the Company’s or Affiliate’s right to terminate the Service of such Participant. No Participant or other Person shall have any claim to be granted any Award, and there is no obligation for uniformity of treatment of Participants, or holders or beneficiaries of Awards. The terms and conditions of Awards and the Committee’s determinations and interpretations with respect thereto need not be the same with respect to each Participant (whether or not such Participants are similarly situated).


10.	Successors and Assigns


	The Plan shall be binding on all successors and assigns of the Company and a Participant, including without limitation, the estate of such Participant and the executor, administrator or trustee of such estate, or any receiver or trustee in bankruptcy or representative of the Participant’s creditors.


11.	Transferability of Awards

Unless otherwise determined by the Committee, an Award shall not be transferable or assignable, provided, however, that (a) an Award may be transferred or assigned by will or by the laws of descent and distribution, and, (b) if permitted by the Committee in its sole discretion, an Award may be granted directly or transferred to the employer of a non-employee director if such non-employee director is obligated to transfer any compensation received as a non-employee director to his or her employer. An Option exercisable after the death of a Participant may be exercised by the legatees, personal representatives or distributees of the Participant.


12.	Amendments or Termination

The Board or the Committee may amend, alter or discontinue the Plan at any time and from time to time, but no amendment, alteration or discontinuation shall be made, (a) without the approval of the shareholders of the Company, if such action would (i) increase the total number of Shares that may be issued under the Plan, (ii) reduce the Option Price of an Option (except to the extent the increase in Shares or reduction in Option Price is made in connection with an adjustment under Section 8 of the Plan), or (iii) require shareholder approval under any applicable New York Stock Exchange listing standards or any applicable rule promulgated by the United States Securities and Exchange Commission or any securities exchange on which Shares are listed or any other applicable laws, and (b) without the consent of a Partici pant, if such action would diminish any of the rights of the Participant under any Award theretofore granted to such Participant under the Plan.


13.	Requirements of Law; International Participants


	The Committee may, in its sole discretion, amend the terms of the Plan or Awards in order (i) to comply with United States federal law or the rules of any securities exchange in the United States

I-6


	or (ii) with respect to Participants who reside or work outside the United States of America, to conform such terms with the requirements of local law or to obtain more favorable tax or other treatment for a Participant, the Company or an Affiliate, and the Committee may, where appropriate, establish one or more sub-plans to reflect such amended or varied provisions.


14.	Choice of Law


	The Plan shall be governed by and construed in accordance with the laws of Bermuda, without regard to conflicts of laws principles.
