OneBeacon 2017 Long-Term Incentive Plan

The Plan shall be administered by the Committee; provided, that each member of the Committee qualifies as (a) a “non-employee director” under Rule 16b-3 of the Exchange Act and (b) an “outside director” under Section 162(m) of the Code. In the event that any member of the Committee does not so qualify, the Plan shall be administered by a subcommittee of at least two Committee members who do so qualify.  If it is later determined that one or more members of the Committee do not so qualify, actions taken by the Committee prior to such determination shall be valid despite such failure to qualify, to the greatest extent permitted by applicable law.

The Committee shall have exclusive authority to select the employees, consultants and directors to be granted Awards, to determine the type, size, terms and conditions of Awards (including those relating to vesting, cancelation, accelerations or waivers thereof, methods and form of settlement, and methods of exercise), and to prescribe the form of the instruments embodying Awards. The Committee shall specify the terms and conditions applicable to such Awards in an Award Agreement. The Committee shall be authorized to interpret the Plan and the Awards granted under the Plan, to establish, amend and rescind any rules and regulations relating to the Plan, and to make any other determinations which it believes necessary or advisable for the administration of the Plan. In connection with any Award, the Committee in its sole discretion may provide for vesting provisions that are different from the default vesting provisions that are contained in the Plan and such alternative provisions shall not be deemed to conflict with the Plan. The Committee may correct any defect or supply any omission or reconcile any inconsistency in the Plan or in any Award in the manner and to the extent the Committee deems desirable to carry it into effect. Any decision of the Committee in the administration of the Plan, as described herein, shall be final and conclusive. Notwithstanding the foregoing, the full Board, acting by a majority of its members in office, shall conduct the general administration of the Plan with respect to Awards granted to Non-Employee Directors.

The Committee may act only by a majority of its members in office, except that the members thereof may authorize any one or more of the members of the Committee or any officer of the Company to execute and deliver documents on behalf of the Committee. The Committee, in its discretion and subject in all instances to applicable law, may delegate to one or more directors or committees of the Board all or part of the Committee’s authority and duties with respect to administering the Plan and granting Awards; provided, however, that in no event shall an officer be delegated the authority to grant awards to, or amend awards held by, the following individuals: (i) individuals who are subject to Section 16 of the Exchange Act, (ii) Covered Employees, or (iii) officers of the Company (or directors) to whom authority to grant or amend Awards has been delegated hereunder. Any delegation hereunder shall be subject to the restrictions and limits that the Board or Committee specifies at the time of such delegation, and the Board may at any time rescind the authority so delegated or appoint a new delegatee. At all times, the delegatee appointed under this Section 2(c) shall serve in such capacity at the pleasure of the Board and the Committee.

Neither the Committee nor any member of the Board, or any administrator of the Plan or any employee or agent of the Company shall be liable for action, determination or interpretation taken or made, or omitted to be taken or made, by him or by any other Person in connection with the Plan or any Award hereunder (unless constituting fraud or a willful criminal act or omission, or as expressly provided by statute). The duties and obligations of the Company, the Committee and each member of the Committee shall be determined only with reference to the Plan, and no implied duties or obligations shall be read into the Plan or any Award Agreement on the part of the Company, the Committee, or any member of the Board or the Committee.

Notwithstanding anything to the contrary contained in the Plan, the Board may, in its sole discretion, at any time and from time to time, grant Awards and administer the Plan with respect to such Awards.  Any such actions by the Board shall be subject to the applicable rules of the New York Stock Exchange (or other principal securities market on which Common Shares are traded). In any such case, the Board shall have all the authority granted to the Committee under the Plan.

Eligible Individuals. Any Non-Employee Director, or any employee or consultant of the Company or any of its Subsidiaries (provided such employee or consultant has executed a OneBeacon Confidentiality and Nonsolicitation Agreement in a form satisfactory to the Company), is eligible to receive an Award hereunder. The Committee shall select which eligible employees, consultants or Non-Employee Directors shall be granted Awards hereunder. No employee, director or consultant shall have a right to receive an Award hereunder, and the grant of an Award to an employee, director or consultant shall not obligate the Committee to continue to grant Awards to such employee, director or consultant in subsequent periods.

Type of Awards. Awards shall be limited to the following seven types: (i) Stock Options, (ii) Restricted Stock, (iii) Restricted Stock Units, (iv) Performance Compensation Awards, (v) Performance Shares, (vi) Performance Units and (vii) Other Incentive Awards.

Subject to adjustment as provided in Section 12, the maximum aggregate number of Shares that may be issued or transferred pursuant to Awards under the Plan is the sum of (i) the number of Shares which as of the Effective Date are available for issuance under the Prior Plan, less any Shares which are the subject of awards made under the Prior Plan after the Effective Date and prior to the date this Plan is approved by the Company’s shareholders, and (ii) any Shares which become available for issuance upon the forfeiture or lapse of awards under the Prior Plan, without such awards having been exercised or settled. All of the Shares subject to the Plan Limit may be issued pursuant to Incentive Stock Options.

To the extent that an Award terminates, expires, or lapses for any reason, or an Award is settled in cash without the delivery of Shares to the Participant, then any Shares subject to the Award shall again be available for the grant of an Award pursuant to the Plan.  Any Shares tendered or withheld to satisfy the grant or exercise price or tax withholding obligation pursuant to any Award shall not be added back to the Plan Limit.  Any Shares repurchased by the Company prior to vesting at par value or for no consideration (including by way of the Repurchase Right) will again be available for Awards.  The payment of Dividend Equivalents in cash in conjunction with any outstanding Awards shall not be counted against

Notwithstanding anything to the contrary in Section 3(c)(i), but subject to adjustment under Section 12, the following special limits shall apply to Shares available for Awards under the Plan:

To the extent permitted by applicable law or any exchange rule, Shares issued pursuant to any Substitute Award shall not be counted against the Plan Limit and shall not be counted against the special limitations set forth in Section 3(c)(iii); provided, however, that Substitute Awards issued or intended as “incentive stock options” within the meaning of Section 422 of the Code shall be counted against the aggregate number of Incentive Stock Options available under the Plan.

Shares delivered by the Company in settlement of Awards may be authorized and unissued shares, shares purchased on the open market or by private purchase or a combination of the foregoing.

A Participant to whom Restricted Stock has been issued shall have, prior to the expiration of the Restricted Period or Repurchase Right, ownership of such Shares, including the right to vote the same and to receive dividends thereon, subject, however, to the options, restrictions and limitations imposed thereon pursuant hereto. The Company, in its discretion, may hold custody during the Restricted Period of any Shares of Restricted Stock.

A Participant to whom Stock Options, Restricted Stock Units, Performance Compensation Awards, Performance Shares, Performance Units or Other Incentive Awards are granted (and any Person succeeding to such Participant’s rights pursuant to the Plan) shall have no rights as a shareholder with respect to any Shares issuable pursuant thereto unless and until the date the Participant becomes the record owner of such Shares. (For the avoidance of doubt, with respect to any Restricted Stock Units, Performance Compensation Awards, Performance Shares, Performance Units or Other Incentive Awards which are ultimately settled in cash, the Participant shall never have any rights as a shareholder with respect to the referenced or underlying Shares of such Awards.) Except as provided in Sections 4, 5(c) or 12, no adjustment shall be made for dividends, distributions or other rights (whether ordinary or extraordinary, and whether in cash, securities or other property) the record date for which is prior to the date the Participant becomes the record owner of such Shares.

Any dividends or Dividend Equivalents permitted by the Plan may be payable in cash, Shares, other securities, other Awards or other property, on a current or deferred basis, on such terms and conditions as may be determined by the Committee, including, without limitation, payment directly to the Participant, withholding of such amounts by the Company subject to vesting of the Award or reinvestment in additional Shares, Restricted Stock or other Awards. Dividend Equivalents may be accumulated in respect of unearned Awards and paid as soon as administratively practicable, but no more than 60 days, after such Awards are earned and become payable or distributable (and the right to any such accumulated dividends or Dividend Equivalents shall be forfeited upon the forfeiture of the Award to which such dividends or Dividend Equivalents relate).

Except as otherwise determined by the Committee, if a Participant’s employment terminates before the payment, exercise, settlement or removal of restrictions with respect to an Award, any subsequent payment, exercise, settlement or removal of restrictions (to the extent not otherwise forfeited) shall be conditioned upon the Participant signing and delivering an effective and irrevocable general release of claims, in the form provided by the Company (“Release”), as consideration for such payment, exercise, settlement or removal of restrictions. The Participant shall be required to execute and deliver such release to the Company within the time period specified in this Section 3(e) (or as set forth in the applicable Award Agreement or other written agreement between the Participant and the Company or its Subsidiary, as applicable) in a manner that complies with Sections 409A and 457A of the Code. The requirement to execute and deliver a Release under this Section release to the Company within the time period specified in this Section 3(e) is referred to as the “Release Condition.”

Unless otherwise set forth in the applicable Award Agreement or other written agreement between the Participant and the Company or its Subsidiary, the Release shall be subject to the following timing requirements:

The per Share exercise price shall not be less than the greater of (i) the Fair Market Value per Share as of the date of grant or (ii) the par value per Share. Notwithstanding the foregoing, the exercise price of an Incentive Stock Option granted to a Ten-Percent Participant shall not be less than the greater of 110% of such Fair Market Value, or the par value per Share.

The Committee shall initially determine the number of Shares to be subject to each Stock Option, which number shall be set forth in the applicable Award Agreement.

The Stock Option shall not be transferable by the Participant other than by will or the laws of descent and distribution, and shall be exercisable during his lifetime only by him.

The Stock Option shall not be exercisable:

after the expiration of (A) ten years from the date it is granted or (B) five years from the date it is granted in the case of an Incentive Stock Options granted to a Ten-Percent Participant, and may be exercised during such period only at such time or times as the Committee may establish;

unless payment in full is made for the Shares being acquired thereunder at the time of exercise (including any U.S. Federal, state or local income or other taxes which the Committee determines are required to be withheld in respect of such shares); such payment shall be made (A) in United States dollars by cash, check or cash equivalent, (B) by tendering to the Company Shares owned by the Person exercising the Stock Option and having a Fair Market Value equal to the amount needed to pay for the aggregate exercise price and all applicable required withholding taxes (provided that such Shares are not subject to any pledge or other security interest), (C) if there is a public market for the Shares at such time, by the Company delivering for sale to a registered securities broker acceptable to the Company a number of the Shares being acquired by the Person exercising the Stock Option being sufficient, after brokerage commissions, to cover the aggregate exercise price thereof and all applicable required withholding taxes, together with instructions to the broker to remit to the Company the aggregate exercise price thereof and amounts sufficient to satisfy all applicable required withholding taxes, and the remainder to the Participant, (D) if there is a public market for the Shares at such time, by means of a “net exercise” procedure effected by withholding the minimum number of Shares otherwise deliverable in respect of a Stock Option that are needed to pay for the aggregate exercise price and all applicable required withholding taxes, (E) by such other method as the Committee may permit or (F) by a combination of the foregoing;

by Participants who were employees of the Company or one of its Subsidiaries at the time of the grant of the Stock Option unless such Participant has been, at all times during the period beginning with the date of grant of the Stock Option and ending on the date three months prior to such exercise, an employee of the Company or a Subsidiary, or of a corporation, or a parent or subsidiary of a corporation, issuing or assuming the Stock Option in a transaction to which Section 424(a) of the Code is applicable, except that:

if such Participant shall cease to be an employee of the Company and its Subsidiaries solely by reason of a period of Related Employment, the Committee, in its direction, may permit such Participant, during such period of Related Employment and for three months thereafter (but in no event after the Stock Option has expired under the provisions of Section 4(d)(i) hereof), to exercise such Stock Option as if he continued to be an employee of the Company and its Subsidiaries; or

if such Participant’s employment with the Company and its Subsidiaries is terminated by the Company due to such Participant’s Disability, he may, at any time within three years from the date of such termination of employment (but in no event after the Stock Option has expired under the provisions of Section 4(d)(i) hereof), exercise the Stock Option with respect to (i) any Shares as to which he could have exercised the Stock Option on such termination date and (ii) subject to the Participant’s satisfaction of the Release Condition, if any portion of the Stock Option is not fully exercisable on such termination date, the number of additional Shares as to which the Stock Option would have become exercisable had he remained an employee through the end of the calendar year in which the termination of employment occurred; or

if such Participant shall die while holding a Stock Option, his executors, administrators, heirs or distributees, as the case may be, at any time within one year after the date of such death (but in no event after the Stock Option has expired under the provisions of Section 4(d)(i) hereof), may exercise the Stock Option with respect to (i) any Shares as to which the decedent could have exercised the Stock Option at the time of his death, and (ii) if the Stock Option is not fully exercisable on the date of his death, the number of additional Shares as to which the Stock Option would have become exercisable had he remained an employee through the end of the calendar year in which his death occurred; provided, however, that if his death occurs during the three-year period following a Disability as described in Section 4(d)(iii)(A) hereof or any period in respect of which the Committee has exercised its discretion to grant continuing exercise rights (including upon Retirement, as provided in Section 4(d)(iii)(C)), this clause (ii) shall not apply; or

if such Participant shall voluntarily terminate his employment with the Company due to Retirement, and the Participant executes and delivers a separation and release agreement in the form provided by the Company, containing noncompetition, nonsolicitation and other restrictive covenants, as well as a general release of claims in the manner contemplated by the Release Condition, the Committee, in its sole discretion, may determine to (i) provide for continued vesting of the Participant’s Stock Option through the last day of the calendar year in which the Participant’s termination of employment occurs (it being understood that any unvested portion of the Stock Option which is not otherwise scheduled to vest through such date shall be forfeited upon termination of employment), (ii) permit such Participant to exercise the Stock Option any time within three years from the date of such Participant’s termination of employment, with respect to any Shares as to which the Participant could have exercised the Stock Option on such termination date plus any additional Shares as to which the Stock Option becomes exercisable by application of clause (i) hereof, and/or (iii) provide for tolling of the applicable post-termination exercise period until the final vesting date; provided, however, that in no event may any post-termination exercise under this subsection 2(d) take place after the Stock Option has expired under the provisions of Section 4(d)(i) hereof; provided, further, that if the Participant breaches the noncompetition, nonsolicitation or other restrictive covenants in his separation and release agreement, then the Participant’s outstanding Stock Option shall be immediately canceled upon such breach, and the full amount recognized from any prior exercise of his Stock Option (and any gain thereto) shall be forfeited and the Participant shall be required to promptly repay such amounts to the Company within ten days following such breach.

The aggregate Fair Market Value of Shares (determined as of the date of grant of the Stock Option) with respect to which Incentive Stock Options granted to any Participant under the Plan are exercisable for the first time by such Participant during any calendar year may not exceed the maximum amount permitted under Section 422(d) of the Code at the time of the Award grant. In the event this limitation would be exceeded in any year, the Participant may elect either (i) to defer to a succeeding year the date on which some or all of such Incentive Stock Options would first become exercisable or (ii) convert some or all of such Incentive Stock Options into non-qualified Stock Options.

No fractional Shares shall be delivered upon the exercise of any Stock Option, but in lieu thereof a cash settlement shall be made.

Notwithstanding anything herein to the contrary, in the event a Change in Control occurs and within 24 months thereafter: (A) there is a Termination Without Cause of an Participant’s employment; or (B) there is a Constructive Termination of an Participant’s employment; or (C) there occurs an Adverse Change in the Plan with respect to an Participant affecting any Award held by such Participant, and if the Participant then holds a Stock Option,

in the case of a Termination Without Cause or a Constructive Termination, the Participant may exercise the entire Stock Option, at any time within 30 days following such Termination Without Cause or such Constructive Termination (but in no event after the Stock Option has expired under the provisions of Section 4(d)(i)); and

in the case of an Adverse Change in the Plan with respect to a Participant, the Participant may exercise the entire Stock Option at any time after such Adverse Change in the Plan until the 30^th day following any subsequent termination of his employment as a result of a Termination Without Cause or a Constructive Termination (but in no event after the Stock Option has expired under the provisions of Section 4(d)(i));

The Committee may grant to Participants Restricted Stock and/or Restricted Stock Unit Awards.

Except as may otherwise be set forth in any Award Agreement, each Award of Restricted Stock shall comply with the following terms and conditions:

The Committee shall determine the number of Shares of Restricted Stock to be issued to a Participant, which number shall be set forth in the applicable Award Agreement.

Restricted Stock may be subject to such restrictions and other terms and conditions as the Committee determines appropriate, including service-based or performance-based vesting requirements, during the applicable Restricted Period. Shares of Restricted Stock issued may not be sold, assigned, transferred, pledged, hypothecated or otherwise disposed of, except by will or the laws of descent and distribution, for the applicable Restricted Period. Upon the expiration of the Restricted Period and the attainment of any other vesting criteria, (A) the restrictions set forth in the applicable Award Agreement shall be of no further force or effect, except as set forth in the Award Agreement, and (B) any dividends attributable to the Restricted Stock that may have been accumulated and withheld by the Committee shall be distributed to the Participant in cash or in Shares having a Fair Market Value (on the date of distribution) equal to the amount of such dividends, upon the release of restrictions on such Share.

Any Shares of Restricted Stock (A) held by a Participant whose employment with the Company and its Subsidiaries terminates prior to the expiration of the Restricted Period for any reason other than by reason of an event described in Section 5(b)(iv), or (B) which fail to vest upon a Participant’s termination of employment after application of Section 5(b)(iv)(B) or (C), as applicable, shall be automatically repurchased by the Company in exchange for their aggregate par value, in a manner intended to comply with the Companies Act 1981 (Bermuda) as determined by the Company (the “Repurchase Right”) upon such termination of employment. For the avoidance of doubt, any rights to dividends that may have been accumulated or withheld during the Restricted Period in respect of the repurchased Shares shall terminate upon such termination of employment, without further action or obligation of the Company.

Upon the grant of Restricted Stock, the Committee shall cause Shares to be registered in the name of the Participant and held in book-entry form subject to the Company’s directions. The Committee also may cause a stock certificate registered in the name of the Participant to be issued. In such event, such certificate shall bear an appropriate legend referring to the Repurchase Right and other restrictions. Any attempt to dispose of any such Shares in contravention of the Repurchase Right and other restrictions shall be null and void and without effect. If Shares issued pursuant to a Restricted Stock Award shall be repurchased pursuant to the Repurchase Right, the Participant to whom the Award was granted, or in the event of his death after such Repurchase Right becomes exercisable, his executor or administrator, shall forthwith deliver to the Secretary of the Company any certificates for the Shares awarded to the Participant, accompanied by such instruments of transfer, if any, as may reasonably be required by the Secretary of the Company.

If a Participant who has been in the continuous employment of the Company or of a Subsidiary shall:

terminate employment during the Restricted Period due to the Participant’s death or Disability, the Repurchase Right and any and all other restrictions on the Restricted Stock Award shall lapse and cease to be effective as of the date on which such termination of employment occurs; provided, that if such termination of employment is due to the Participant’s Disability, the Participant (or his representative, as appropriate) must satisfy the Release Condition; provided, further, that for purposes of the foregoing, any performance condition on such Restricted Stock Award shall be deemed satisfied at the target level;

Retire during the Restricted Period, and the Participant executes and delivers a separation and release agreement in the form provided by the Company, containing noncompetition, nonsolicitation and other restrictive covenants, as well as a general release of claims in the manner contemplated by the Release Condition, the Committee, in its sole discretion, may determine to provide for (i) continued vesting of the Participant’s Restricted Stock Award through the last day of the calendar year in which the Participant’s termination of employment occurs (it being understood that any unvested Shares of Restricted Stock which are not otherwise scheduled to vest through such date shall be forfeited upon termination of employment), and (ii) tolling of the Repurchase Right until such final vesting date; provided, that if the Restricted Stock Award is a Performance Compensation Award or otherwise subject to performance-based vesting requirements, any such vesting credit applied upon Retirement shall be subject to the achievement of applicable Performance Objectives; provided, further, that if the Participant breaches the noncompetition, nonsolicitation or other restrictive covenants in his separation and release agreement, then upon such breach, the Participant’s Restricted Stock Award shall be automatically repurchased pursuant to the Repurchase Right, and the full amount recognized from any prior vesting of such Restricted Stock Award (and any gain thereto) shall be forfeited and the Participant shall be required to promptly repay such amounts to the Company within ten days following such breach; or

cease to be an employee of the Company and its Subsidiaries solely by reason of a period of Related Employment, the Committee, in its sole discretion, may determine to provide for continued vesting of the Participant’s Restricted Stock Award during such period of Related Employment as if the Participant continued to be an employee of the Company and its Subsidiaries.

In the event that, within 24 months after a Change in Control and during the Restricted Period:

there is a Termination Without Cause of the employment of a Participant;

there is a Constructive Termination of the employment of a Participant; or

there occurs an Adverse Change in the Plan with respect to a Participant, then

Except as may otherwise be set forth in any Award Agreement, each Award of Restricted Stock Units shall comply with the following terms and conditions:

The Committee shall determine the target number of Restricted Stock Units to be granted to a Participant, which number shall be set forth in the applicable Award Agreement.

Each Restricted Stock Unit will represent one Share and the value of such Share shall be credited to a notional account maintained by the Company. No Shares shall be issued at the time an Award of Restricted Stock Units is made, and the Company will not be required to set aside a fund for the payment of any such Award. At the sole discretion of the Committee, an Award Agreement may provide that each Restricted Stock Unit shall also entitle the Participant to Dividend Equivalents.

Restricted Stock Units may be subject to such restrictions and other terms and conditions as the Committee determines appropriate, including service-based or performance-based vesting requirements, during the applicable Restricted Period. Unless otherwise provided by the Committee in an Award Agreement and subject to the Release Condition (if applicable), upon the expiration of the Restricted Period and the attainment of any other vesting criteria established by the Committee, with respect to any outstanding Restricted Stock Units, the Company shall deliver to the Participant, or his beneficiary (via book entry notation or, if applicable, in stock certificate form), one Share (or other securities or other property, as applicable) for each such outstanding Restricted Stock Unit which has not then been forfeited and with respect to which the applicable restrictions have expired and any other such vesting criteria are attained.

Except as otherwise provided in a Restricted Stock Unit Award Agreement or in Sections 5(c)(v) or (vi), Restricted Stock Units shall be canceled if the Participant’s continuous employment with the Company and its Subsidiaries shall terminate for any reason prior to the end of expiration of the applicable Restricted Period. For the avoidance of doubt, any Dividend Equivalents that may have been accumulated or withheld during the Restricted Period in respect of any forfeited Restricted Stock Units shall terminate without further action or obligation of the Company.

If a Participant who has been in the continuous employment of the Company or of a Subsidiary shall:

In the event that, within 24 months after a Change in Control and during the Restricted Period:

there is a Termination Without Cause of the employment of a Participant;

there is a Constructive Termination of the employment of a Participant; or

there occurs an Adverse Change in the Plan with respect to a Participant, then

Unless payment is deferred in accordance with Section 409A of the Code and subject to the Release Condition (if applicable), the Committee shall cause an amount equal to the value of the Restricted Stock Units earned by the Participant to be paid to him or his beneficiary no later than 2-1/2 months after the end of the Company’s fiscal year in which such Restricted Stock Units are earned. Restricted Stock Units may be settled in cash, in Shares or partly in cash and partly in Shares as determined by the Committee. If a cash payment is made in lieu of delivering Shares, the amount of such payment shall be equal to the Fair Market Value of the Shares as of the date on which the applicable restrictions lapsed with respect to such Restricted Stock Units.

Generally. Performance Compensation Awards are intended to qualify as “performance-based compensation” under Section 162(m) of the Code. The Committee shall have the authority to designate any Award as a Performance Compensation Award, including (i) Restricted Stock, the restrictions with respect to which lapse upon the attainment of specified Performance Objectives (together with any applicable service-based or other vesting conditions), and (ii) any Restricted Stock Units or other performance or incentive Awards described in Sections 5, 7, 8 or 9 that vest or become exercisable or payable upon the attainment of one or more specified Performance Objectives (together with any applicable service-based or other vesting conditions). In addition, the Committee shall have the authority to make an award of a cash bonus to any Participant and designate such Award as a Performance Compensation Award intended to qualify as “performance-based compensation” under Section 162(m) of the Code. Notwithstanding the foregoing, (i) any Award to a Participant who is a Covered Employee for a fiscal year that satisfies the requirements of this Section 6 may be treated as a Performance Compensation Award in the absence of any such Committee designation and (ii) if the Company determines that a Participant who has been granted an Award designated as a Performance Compensation Award is not (or is no longer) a Covered Employee, the terms and conditions of such Award may be modified without regard to any restrictions or limitations set forth in this Section 6 (but subject otherwise to the provisions of Section 16). The Committee may in its sole discretion grant Awards to other Participants that are based on Performance Criteria or Performance Objectives but that do not satisfy the requirements of this Section 6 and that are not intended to qualify as “performance-based compensation” under Section 162(m) of the Code.

Committee Discretion on Performance Compensation Awards. The Committee may select the length of an Award Period, the type(s) of Performance Compensation Awards to be issued, the Performance Criteria used to establish the Performance Objective(s), the kind(s) and/or level(s) of the Performance Objective(s) and the Performance Formula. Within the first 90 days of an Award Period (or the maximum period allowed under Section 162(m) of the Code), the Committee shall determine each of the matters enumerated in the immediately preceding sentence and record the same in writing (which may be in the form of minutes of a meeting of the Committee).

Certification; Determination of Awards. Following the completion of an Award Period, the Committee shall review and certify in writing (which may be in the form of minutes of a meeting of the Committee) whether, and to what extent, the Performance Objectives for the Award Period have been achieved and, if so, calculate and certify in writing (which may be in the form of minutes of a meeting of the Committee) that amount of the Performance Compensation Award earned for the period based upon the Performance Formula. The Committee shall then determine the amount of each Participant’s Performance Compensation Award actually payable for the Award Period.

Negative Discretion. In determining the amount of each Participant’s Performance Compensation Award actually payable for the Award Period, the Committee may, in its sole and absolute discretion, reduce or eliminate the size of the Performance Compensation Award consistent with Section 162(m) of the Code, even if applicable Performance Objectives have been attained; provided, that following a Change in Control, this discretion shall not apply to Awards outstanding at the time of the Change in Control.

Payment of Performance Awards. Unless otherwise provided in the applicable Award Agreement and only to the extent otherwise permitted by Section 162(m)(4)(C) of the Code, with respect to any Performance Compensation Award, the Participant must be employed by the Company or a Subsidiary throughout the Award Period. Unless otherwise provided in the applicable Award Agreement or permitted by Section 162(m) of the Code, the Committee shall not have the discretion to (i) provide payment or delivery in respect of a Performance Compensation Award for an Award Period if the Performance Objectives for such Award Period have not been attained; or (ii) increase a Performance Compensation Award above the applicable limitations set forth in Section 3(c).

Timing of Award Payments. Unless otherwise provided in the applicable Award Agreement, Performance Compensation Awards granted for an Award Period shall be paid to Participants as soon as administratively practicable following completion of the certifications required by this Section 6. Any deferral of payment or settlement of any Performance Compensation Award shall not (between (x) the date as of which the Award is deferred and (y) the payment or settlement date) increase (i) with respect to a Performance Compensation Award that is payable in cash, by a measuring factor for each fiscal year greater than a reasonable rate of interest set by the Committee, or (ii) with respect to a Performance Compensation Award that is payable in Shares, by an amount greater than the appreciation of a Share from the date such Award is deferred to the payment date. Unless otherwise provided in an Award Agreement, any Performance Compensation Award that is deferred and is otherwise payable in Shares may be credited (during the period between the date as of which the Award is deferred and the payment date) with Dividend Equivalents.

Additional Limitations. Notwithstanding any other provision of the Plan, Performance Compensation Awards shall be subject to any additional limitations set forth in Section 162(m) of the Code or any regulations or rulings issued thereunder that are requirements for qualification as “performance-based compensation” under Section 162(m) of the Code, and the Plan and the Award Agreement shall be deemed amended to the extent necessary to conform to such requirements.

The Committee shall determine the target number of Performance Shares to be granted to a Participant, which number shall be set forth in the applicable Award Agreement. Performance Share Awards may be granted in different classes or series having different terms and conditions.

The Actual Value of a Performance Share Award shall be the product of (i) the target number of Performance Shares subject to the Performance Share Award, (ii) the Performance Percentage (as determined below) applicable to the Performance Share Award and (iii), if the Performance Share Award is settled in cash, the Fair Market Value of a Share on the date the Committee certifies the Performance Percentage. The “Performance Percentage” applicable to a Performance Share Award shall be a percentage of no less than 0% and no more than 200%, which percentage shall be determined by the Committee based upon the extent to which the Performance Objectives (as determined below) established for such Award are achieved during the Award Period. The method for determining the applicable Performance Percentage shall also be established by the Committee.

At the time each Performance Share Award is granted, the Committee shall establish Performance Objectives to be attained within the Award Period as the means of determining the Performance Percentage applicable to such Award, in the manner contemplated by Section 6(b).

The Award Period in respect of any grant of a Performance Share Award shall be such period as the Committee shall determine commencing as of the beginning of the fiscal year of the Company in which such grant is made. An Award Period with respect to a Performance Share Award may contain a number of sub-periods designated as “Performance Periods.” Each Performance Period shall commence on or after the first day of the Award Period and shall end no later than the last day of the Award Period. If the Committee does not specify in a Performance Share Award Agreement or elsewhere the Performance Periods contained in an Award Period, each 12-month period beginning with the first day of such Award Period shall be deemed to be a Performance Period.

Performance Shares shall be canceled if the Participant’s continuous employment with the Company and its Subsidiaries shall terminate for any reason prior to the end of the Award Period, except (i) by reason of a period of Related Employment (unless otherwise determined by the Committee), (ii) as otherwise specified in this Section 7(e) or in Section 7(f) or (iii) as otherwise determined by the Committee. Notwithstanding the foregoing, if a Participant’s employment shall terminate due to death or Disability, the provisions of Section 5(c)(v)(A) shall apply mutatis mutandis as if fully set forth herein with respect to Performance Shares.

If within 24 months after a Change in Control:

there is a Termination Without Cause of the employment of a Participant;

there is a Constructive Termination of the employment of a Participant; or

there occurs an Adverse Change in the Plan with respect to a Participant (any such occurrence under the above clauses (i), (ii) or (iii), a “Trigger Event”), then

Except as otherwise provided in Sections 7(e) or (f), as soon as practicable after the end of the Award Period or such earlier date as the Committee in its sole discretion may designate, the Committee shall (i) determine, based on the extent to which the applicable Performance Objectives have been achieved, the Performance Percentage applicable to an Award of Performance Shares, (ii) calculate the Actual Value of the Performance Share Award and (iii) shall certify in writing the foregoing, in the manner contemplated by Section 6.

The Committee shall determine (i) the target number of Performance Units to be granted to a Participant and (ii) the amount designated as the Unit Value or method for calculating the Unit Value, which shall be set forth in the applicable Award Agreement. Performance Unit Awards may be granted in different classes or series having different terms and conditions.

The Actual Value of a Performance Unit Award shall be the product of (i) the target number of Performance Units subject to the Performance Unit Award, (ii) the Performance Percentage (as determined below) applicable to the Performance Unit Award and (iii) the Unit Value (or, if the relevant Performance Unit is settled in Shares, the Unit Value divided by the Fair Market Value of a Share on the date the Committee certifies the Performance Percentage). The “Performance Percentage” applicable to a Performance Unit Award shall be a percentage of no less than 0% and no more than 200%, which percentage shall be determined by the Committee based upon the extent to which the Performance Objectives (as determined below) established for such Award are achieved during the Award Period.

If the Committee does not specify in a Performance Unit Award Agreement or elsewhere the Award Periods contained in an Award Period, each 12-month period beginning with the first day of such Award Period shall be deemed to be a Performance Period.

Performance Units shall be canceled if the Participant’s continuous employment with the Company and its Subsidiaries shall terminate for any reason prior to the end of the Award Period, except (i) by reason of a period of Related Employment (unless otherwise determined by the Committee), (ii) as otherwise specified in this Section 8(e) or in Section 8(f) or (iii) as otherwise determined by the Committee. Notwithstanding the foregoing, if a Participant’s employment shall terminate due to death or Disability, the provisions of Section 5(c)(v)(A) shall apply mutatis mutandis as if fully set forth herein with respect to Performance Units.

If within 24 months after a Change in Control, a Trigger Event occurs, then with respect to Performance Unit Awards that were outstanding on the date of the Trigger Event (each, an “Applicable Award”), each such Applicable Award shall be immediately canceled and, in respect thereof, such Participant, or the Participant’s legal representative, as the case may be, shall be entitled to receive a cash payment equal to the product of (A) the target number of Performance Units for such Applicable Award multiplied by (B) a fraction, the numerator of which is equal to the number of full or partial months from the beginning of the Award Period through the date of the Trigger Event, and the denominator of which is equal to the total number of months within such Award Period, multiplied by (C) the greater of (i) the Unit Value immediately prior to the Change in Control and (ii) the Unit Value on the date the applicable Trigger Event occurs, multiplied by (D) the greater of (i) the Performance Percentage calculated through the end of the quarter preceding the Trigger Event, or (ii) 100%. For purposes of this Section 8(f), the Performance Percentage calculated as of the end of the quarter preceding the Trigger Event shall be calculated using actual financial results achieved through the end of the quarter preceding the Trigger Event and including any gain or loss related to the Change in Control as it relates to the Company recognized or to be recognized in the Company’s consolidated financial statements prepared in accordance with GAAP. If following a Change in Control, a Participant’s employment remains continuous through the end of an Award Period, then the Participant shall be paid with respect to such Awards for which he would have been paid had there not been a Change in Control and the Actual Value shall be determined in accordance with Section 8(g) below.

Except as otherwise provided in Sections 8(e) and (f), as soon as practicable after the end of the Award Period or such earlier date as the Committee in its sole discretion may designate, the Committee shall (i) determine, based on the extent to which the applicable Performance Objectives have been achieved, the Performance Percentage applicable to an Award of Performance Units, (ii) calculate the Actual Value of the Performance Unit Award and (iii) shall certify in writing the foregoing, in the manner contemplated by Section 6.

Compliance with Laws. No Shares shall be issued hereunder unless counsel for the Company shall be satisfied that such issuance will be in compliance with applicable U.S. Federal and state securities laws, Bermuda law or other applicable laws, rules, and regulations, and to such approvals by governmental agencies as may be required.

The Committee may cancel an Award or any portion thereof if it determines that legal or contractual restrictions and/or blockage and/or other market considerations would make the Company’s acquisition of Shares from the public markets, the Company’s issuance of Shares to the Participant, the Participant’s acquisition of Shares from the Company and/or the Participant’s sale of Shares to the public markets, illegal, impracticable or inadvisable.

Tax Withholding. The Company and its Subsidiaries shall have the right and is hereby authorized to deduct from any payment made under the Plan (in cash, Shares, other securities or other property) any U.S. Federal, state or local income or other taxes required by law to be withheld with respect to such payment, and to take such other action as the Committee or the Company deem necessary to satisfy all obligations for the payment of such withholding taxes. Unless otherwise provided by the Company, tax withholding shall be at the applicable minimum statutory rate. It shall be a condition to the obligation of the Company to issue Shares upon exercise of a Stock Option, upon settlement of a Stock Appreciation Right, vesting of Restricted Stock or Performance Share (if applicable) or upon vesting or payment of a Performance Unit or a Restricted Stock Unit that the Participant (or any beneficiary or Person entitled to payment pursuant to the Plan) pay to the Company, upon its demand, such amount as may be required by the Company for the purpose of satisfying any liability to withhold U.S. Federal, state or local income or other taxes. If the amount requested is not paid, the Company may refuse to issue Shares.

Expenses. The expenses of the Plan shall be borne by the Company. However, if an Award is made to an employee of a Subsidiary:

if such Award results in payment of cash to the Participant, such Subsidiary shall pay to the Company an amount equal to such cash payment; and

if the Award results in the issuance to the Participant of Shares, such Subsidiary shall pay to the Company an amount equal to Fair Market Value thereof, as determined by the Committee, on the date such Shares are issued (or, in the case of issuance of Restricted Stock or of Shares subject to transfer and forfeiture conditions, equal to the Fair Market Value thereof on the date on which such Shares are no longer subject to applicable restriction), minus the amount, if any received by the Company in exchange for such Shares.

No Trust or Fund Created. The Plan shall be unfunded. The Company shall not be required to establish any special or separate fund or to make any other segregation of assets to assure the payment of any Award under the Plan. With respect to any payments not yet made to a Participant pursuant to an Award, nothing contained in this Plan or any Award Agreement shall give the Participant any rights that are greater than those of a general creditor of the Company or any of its Subsidiaries.

Acceptance of Award. By accepting any Award or other benefit under the Plan, each Participant and each Person claiming under or through him shall be conclusively deemed to have indicated his acceptance and ratification of, and consent to, any action taken under the Plan by the Company, the Board or the Committee.

No election under Section 83(b) of the Code (to include in gross income in the year of transfer the amounts specified in Section 83(b) of the Code) or under a similar provision of law may be made unless expressly permitted by the terms of the applicable Award Agreement or by action of the Committee in writing prior to the making of such election.  If a Participant, in connection with the acquisition of Shares under the Plan or otherwise, is expressly permitted under the terms of the applicable Award Agreement or by such Committee action to make such an election and the Participant makes the election, the Participant shall notify the Committee of such election within ten days of filing notice of the election with the Internal Revenue Service or other governmental authority, in addition to any filing and notification required pursuant to regulations issued under Section 83(b) of the Code or any other applicable provision.

Notification of Disqualifying Dispositions. If any Participant shall make any disposition of Shares delivered pursuant to the exercise of an Incentive Stock Option under the circumstances described in Section 421(b) of the Code (relating to certain disqualifying dispositions) or any successor provision of the Code, such Participant shall notify the Company of such disposition within ten days of such disposition.

No Representations or Covenants With Respect to Tax Qualification. Although the Company may endeavor to (i) qualify an Award for favorable U.S. or non-U.S. tax treatment or (ii) avoid adverse tax treatment, the Company makes no representation to that effect and expressly disavows any covenant to maintain favorable or avoid unfavorable tax treatment. The Company shall be unconstrained in its corporate activities without regard to the potential negative tax impact on Participants under the Plan.

No Interference. The existence of the Plan, any Award Agreement and the Awards granted hereunder shall not affect or restrict in any way the right or power of the Company, the Board, the Committee or the shareholders of the Company to make or authorize any adjustment, recapitalization, reorganization or other change in the Company’s capital structure or its business, any merger or consolidation of the Company, any issue of stock or of options, warrants or rights to purchase stock or of bonds, debentures, preferred or prior preference stocks whose rights are superior to or affect the Common Shares or the rights thereof or which are convertible into or exchangeable for Common Shares, or the dissolution or liquidation of the Company or any Affiliate, or any sale or transfer of all or any part of their assets or business, or any other corporate act or proceeding, whether of a similar character or otherwise.

Obligations Binding on Successors; Divisional Sale. The obligations of the Company under this Plan shall be binding upon any successor corporation or organization resulting from the merger, consolidation or other reorganization of the Company, or upon any successor corporation or organization succeeding to substantially all of the assets and business of the Company. If a Person who acquires a Subsidiary or business unit agrees to fully assume the obligations of the Company under a Participant’s outstanding Awards under the Plan or to replace them with similar or like awards with no diminution of value of the Awards, then the Company shall be released from its obligations to such Participant with respect to such Awards without the requirement of any action by or approval of the Participant. If a Person who acquires a Subsidiary or business unit declines to assume or replace such obligations, the Company shall remain obligated under the Awards as provided in the Plan.

Indemnification. To the extent allowable pursuant to applicable law, each member of the Committee or of the Board shall be indemnified and held harmless by the Company from any loss, cost, liability, or expense that may be imposed upon or reasonably incurred by such member in connection with or resulting from any claim, action, suit, or proceeding to which he may be a party or in which he may be involved by reason of any action or failure to act pursuant to the Plan and against and from any and all amounts paid by him in satisfaction of judgment in such action, suit, or proceeding against him, provided that he gives the Company an opportunity, at its own expense, to handle and defend the same before he undertakes to handle and defend it on his own behalf.  The foregoing right of indemnification shall not be exclusive of any other rights of indemnification to which such Persons may be entitled pursuant to the Company’s Bye-Laws, as a matter of law, or otherwise, or any power that the Company may have to indemnify them or hold them harmless.

Reliance on Reports. Each member of the Committee and each member of the Board (and their respective designees) shall be fully justified in acting or failing to act, as the case may be, and shall not be liable for having so acted or failed to act in good faith, in reliance upon any report made by the independent registered public accounting firm of the Company and

No Limit on Other Compensation Arrangements.  Nothing contained in this Plan shall prevent the Company or any Subsidiary from adopting or continuing in effect other compensation arrangements, which may, but need not, provide for the grant of options, restricted stock, shares, performance shares, performance units, stock appreciation rights, other types of equity-based awards (subject to shareholder approval if such approval is required) and cash awards, and such arrangements may be either generally applicable or applicable only in specific cases.

Relationship to other Benefits. No payment pursuant to the Plan shall be taken into account in determining any benefits under any pension, retirement, savings, profit sharing, group insurance, welfare or other benefit plan of the Company or any Subsidiary except to the extent otherwise expressly provided in writing in such other plan or an agreement thereunder.

Severability. If any provision of the Plan or any Award or Award Agreement is or becomes or is deemed to be invalid, illegal, or unenforceable in any jurisdiction or as to any person or entity or Award, or would disqualify the Plan or any Award under any law deemed applicable by the Committee, such provision shall be construed or deemed amended to conform to the applicable laws, or if it cannot be construed or deemed amended without, in the determination of the Committee, materially altering the intent of the Plan or the Award, such provision shall be construed or deemed stricken as to such jurisdiction, person or entity or Award and the remainder of the Plan and any such Award shall remain in full force and effect.

Titles and Headings; Gender; References to Law. The titles and headings of the Sections in the Plan are for convenience of reference only and, in the event of any conflict, the text of the Plan, rather than such titles or headings, shall control. Masculine pronouns and other words of masculine gender shall refer to both men and women. References to sections of the Code, the Exchange Act, the Securities Act or other statutes shall include any amendment or successor thereto, and any rules, regulations or other interpretative guidance under such statute.

At the sole discretion of the Committee, the payment or settlement of an Award may be deferred by the Committee or the Participant in accordance with procedures adopted by the Committee. Notwithstanding the preceding sentence, if an Award is subject to Section 409A or 457A of the Code, or the deferral of such Award or settlement causes the Award to be subject to Section 409A or 457A of the Code, any such deferral must comply (as determined by the Company) with Section 409A and 457A of the Code, as applicable, and the terms of the Plan and Award Agreement shall be interpreted consistent therewith.

Notwithstanding any provision of the Plan or any Award Agreement to the contrary, each Award granted under the Plan either shall be excepted from the requirements of Section 409A or 457A of the Code, as applicable, or shall comply with the requirements of Section 409A or 457A of the Code, and the terms of the Plan and each Award Agreement shall be interpreted consistent therewith. An Award that is excepted from the requirements of Section 409A of the Code may not be amended or otherwise modified in such a manner that the Award becomes subject to Section 409A of the Code unless the Committee expressly provides that the amendment or modification is intended to subject the Award to the requirements of Section 409A of the Code and the amended or modified Award complies with such requirements. An Award that is subject to the requirements of Section 409A or 457A of the Code may not be amended or otherwise modified in such a manner that the Award no longer complies with Section 409A or 457A of the Code, as applicable (as determined by the Company), unless the

Each Participant is solely responsible and liable for the satisfaction of all taxes and penalties that may be imposed on or in respect of such Participant in connection with this Plan, including any taxes and penalties under Section 409A and 457A of the Code, as applicable, and neither the Company nor any Affiliate shall have any obligation to indemnify or otherwise hold such Participant or any beneficiary harmless from such taxes or penalties. With respect to any Award that is considered “deferred compensation” subject to Section 409A or 457A of the Code, as applicable, references in the Plan to “termination of employment” (and substantially similar phrases) shall mean “separation from service” within the meaning of Section 409A of the Code. For purposes of Section 409A of the Code, each of the payments that may be made in respect of any Award granted under the Plan is designated as a separate payment.

Notwithstanding anything in the Plan to the contrary, if a Participant is a “specified employee” within the meaning of Section 409A(a)(2)(B)(i) of the Code, no payments or deliveries in respect of any Awards that are “deferred compensation” subject to Section 409A of the Code shall be made to such Participant prior to the date that is six months after the date of such Participant’s “separation from service” or, if earlier, the Participant’s date of death. All such delayed payments or deliveries will be paid or delivered (without interest) in a single lump sum on the next available payroll date following the earliest date permitted under Section 409A of the Code.

In the event that the timing of payments in respect of any Award that would otherwise be considered “deferred compensation” subject to Section 409A of the Code would be accelerated upon the occurrence of (i) a Change in Control, no such acceleration shall be permitted unless the event giving rise to the Change in Control satisfies the definition of a change in the ownership or effective control of a corporation, or a change in the ownership of a substantial portion of the assets of a corporation pursuant to Section 409A of the Code or (ii) a Disability, no such acceleration shall be permitted unless the Disability also satisfies the definition of “Disability” pursuant to Section 409A of the Code.

Subject to any applicable law or government regulation, to any requirement that must be satisfied if the Plan is intended to be a shareholder-approved plan for purposes of Section 162(m) of the Code, to the rules of the New York Stock Exchange or any successor exchange or quotation system on which the Shares may be listed or quoted, and for changes in GAAP to new accounting standards (in each case, as determined by the Company), the Plan may be amended at any time and from time to time by the Board, but no amendment which increases the aggregate number of Shares which may be issued pursuant to the Plan or the class of persons eligible to participate shall be effective unless and until the same is approved by the shareholders of the Company.  No amendment of the Plan shall materially and adversely affect any right of any Participant with respect to any Award previously granted without such Participant’s written consent, unless the Board determines that such amendment is required or advisable in order for the Company, the Plan or the Award to satisfy any applicable law or regulation.

The Committee may waive any conditions or rights under, amend any terms of, or alter, suspend, discontinue, cancel or terminate any Award theretofore granted or any associated Award Agreement, prospectively or retroactively (including after a Participant’s termination of employment or service with the Company and its Subsidiaries); provided, however, that, except as set forth in the Plan, unless otherwise provided by the Committee in the applicable Award Agreement or unless the Committee determines that such either is required or advisable

the adoption of a resolution of the Board terminating the Plan; or

ten years from the date the Plan is initially or subsequently approved and adopted by the shareholders of the Company in accordance with Section 19 hereof.
