4. Term of Option. This Option will expire on the seventh (7th) anniversary of the Grant Date (the “Expiration Date”) and must be exercised, if at all, on or before the earlier of the Expiration Date or the date on which this Option is earlier terminated in accordance with the provisions of Section 5 or 6 of this Agreement.

5. Termination of Employment. Subject to Section 6 and the terms of any employment agreement between the Grantee and the Company or any Affiliate or Subsidiary, if the Grantee’s employment with the Company and its affiliates terminates for any reason prior to the final Vesting Date, to the extent the Option has not yet vested in accordance with Section 4, it will automatically be forfeited and cancelled by the Company upon such termination of employment, and to the extent (and only to the extent) that it is vested on the date the Grantee’s employment terminates, the Option may be exercised by the Grantee no later than 90 days after the date of such termination (but in no event later than the Expiration Date), except as follows.

(a) By the Company for Cause. If the Grantee’s employment is terminated by the Company (or any Subsidiary or Affiliate) for Cause, upon such termination of employment the Option will automatically be forfeited in full and cancelled by the Company and any portion of the Option that had previously vested will immediately cease to be exercisable. For purposes of this Agreement, “Cause” means the Grantee’s (i) conviction, or plea of nolo contendere (or a similar plea), in a criminal proceeding; (ii) misconduct; (iii) dishonesty; (iv) violation of any law, rule, regulation of any governmental authority, securities exchange or association or any other regulatory or self-regulatory body or agency applicable to the Grantee or the Company, or any material violation of the Company’s policies or procedures; (v) willful or repeated failure or refusal to perform the Grantee’s duties satisfactorily; (vi) engaging in any activity deemed by the Committee to be contrary or harmful to the interests of the Company; or (vii) such other or different circumstances as the Committee may determine to constitute Cause; in each case as determined by the Committee, which determination will be final, binding and conclusive; provided, however, that if “Cause” is defined in an employment agreement between the Grantee and the Company, that definition will apply in lieu of the definition set forth herein.

(b) Death or Disability. If the Grantee’s termination of employment is due to the Grantee’s death or Disability, the Option will immediately vest in full as of the date of such termination and to the extent that the Option is vested on the date of such termination, the Option may be exercised by the Grantee (or his/her estate or guardian, as the case may be) no later than 1 year after the date of the Grantee’s Death or Disability but in no event later than the Expiration Date. For purposes of this Agreement, “Disability” means the Grantee’s total and permanent disability in accordance with the Company’s long-term disability plan, or if no such plan is applicable to the Grantee, as determined by the Committee in its sole discretion; provided, however, that if “Disability” is defined in an employment agreement between the Grantee and the Company, that definition will apply lieu of the definition set forth herein.

(c) Retirement. If the Grantee’s termination of employment is by reason of Retirement and if the Grantee has completed at least 10 years of continuous service with the Company and its Subsidiaries and Affiliates (including service with any Man Group plc entity before the Effective Date of the Plan) at the time of such termination (or such shorter period of service as determined by the Committee), the Committee may in its sole discretion provide that the Option (i) will not be forfeited, but will remain outstanding and continue to vest in accordance with this

Agreement notwithstanding the Grantee’s termination of employment or (ii) will vest on a pro rata basis, such that effective as of the date of such termination, the Option will be vested in respect of the aggregate number of Option Shares subject to the Option multiplied by the greater of (A) one-third and (B) a fraction, the numerator of which is the number of days that have elapsed from and including the Grant Date through the effective date of the Grantee’s termination of employment, and the denominator of which is 1,095 (the “Pro-Rata Portion”), and the Option in respect of the remainder of the Option Shares will be forfeited. To the extent that the Option is vested on the date of the Grantee’s termination for Retirement or thereafter (after giving effect to any accelerated or continued vesting that may be provided for by the Committee pursuant to this Section 5(c)), the Option may be exercised by the Grantee no later than 5 years after the date of such termination, but in no event later than the Expiration Date. For purposes of this Agreement, “Retirement” means a termination after age 60 in accordance with the retirement policies of the Company (or, as applicable, one of its Subsidiaries or Affiliates).

(d) By the Company for Redundancy. If the Grantee’s employment is terminated by the Company (or any Subsidiary or Affiliate) for reasons of Redundancy (which for avoidance of doubt does not include a termination for death, Disability, Retirement or Cause), the Option will vest in respect of the Pro Rata Portion of Option Shares as of the effective date of the Grantee’s termination of employment, and the remainder of the Option will be forfeited. To the extent that the Option is vested on the date of the Grantee’s termination for reasons of Redundancy (after giving effect to any accelerated vesting that may be provided for by the Committee pursuant to this provision), the Option may be exercised by the Grantee no later than 3 years after the date of such termination, but in no event later than the Expiration Date. For purposes of this Agreement, whether a termination of the Grantee’s employment is for reasons of “Redundancy” will be determined by the Committee in its sole discretion.

6. Change in Control. Notwithstanding any other provision of this Agreement or the Plan, upon a Change in Control, the Option will vest in full and, subject to applicable law, become exercisable in accordance with Section 13 of the Plan.

7. Manner of Exercise.

(a) Share Option Exercise Agreement. To exercise this Option, the Grantee (or in the case of exercise after the Grantee’s death, the Grantee’s executor, administrator, heir or legatee, as applicable) must deliver to the Company an executed share option exercise agreement in such form as may be required by the Company from time to time (the “Exercise Agreement”), which will set forth, inter alia, the Grantee’s election to exercise this Option and the number of Shares being purchased. If someone other than the Grantee exercises this Option, then such person must submit documentation reasonably acceptable to the Company that such person has the right to exercise this Option.

(b) Limitations on Exercise. This Option may not be exercised unless such exercise is in compliance, to the reasonable satisfaction of the Committee, with all applicable foreign, federal and state securities laws, as they are in effect on the date of exercise. In addition, this Option may not be exercised if the Committee determines that an event constituting Cause has occurred during the Grantee’s employment with the Company and its Subsidiaries and Affiliates.

(c) Payment. The Exercise Agreement will be accompanied by full payment of the Option Price for each of the Shares being purchased by the Grantee (such aggregate amount, the “Exercise Price”) in cash (or by certified check), or where permitted by law:

(i) by tender of Shares (that unless otherwise determined by the Committee, are free and clear of all liens, claims, encumbrances or security interests) having a Fair Market Value (determined on the date of exercise) equal to the Exercise Price;

(ii) provided that a public market for the Shares exists: (A) through a “same day sale” commitment from the Grantee and an independent broker-dealer that is acceptable to the Company (a “Broker-Dealer”) whereby the Grantee irrevocably elects to exercise this Option and to sell a portion of the Shares so purchased to pay for the Exercise Price and whereby the Broker-Dealer irrevocably commits upon receipt of such Shares to forward the Exercise Price directly to the Company; or (B) through a “margin” commitment from the Grantee and a Broker-Dealer whereby the Grantee irrevocably elects to exercise this Option and to pledge the Shares so purchased to the Broker-Dealer in a margin account as security for a loan from the Broker-Dealer in the amount of the Exercise Price, and whereby the Broker-Dealer irrevocably commits upon receipt of such Shares to forward the Exercise Price directly to the Company;

(iii) by any combination of the foregoing; or

(iv) at the discretion of the Committee and to the extent permitted by law, such other method as may be prescribed from time to time.

8. Tax Withholding. Prior to the issuance of the Shares upon exercise of this Option, the Grantee will pay, or otherwise provide for to the satisfaction of the Company, any applicable federal, state, local and foreign withholding obligations of the Company. To the extent permitted by law, the Grantee may provide for payment of withholding taxes upon exercise of this Option by requesting that the Company retain Shares with a Fair Market Value (determined as of the date of exercise) equal to the statutory minimum amount of taxes required to be withheld. In such case, the Company will issue the net number of Shares to the Grantee by deducting the Shares retained from the Shares issuable upon exercise of this Option.

9. Issuance of Shares. As promptly as is practicable after the receipt of the Exercise Agreement, in form and substance reasonably satisfactory to counsel for the Company, payment of the Exercise Price and satisfaction of applicable withholding requirements, the Company will issue the Option Shares registered in the name of the Grantee, the Grantee’s authorized assignee or the Grantee’s legal representative, as applicable, and will deliver certificates representing the Option Shares with the appropriate legends affixed thereto. The Company may reasonably postpone such issue and delivery until it receives satisfactory proof that the issuance of such Option Shares will not violate any of the provisions of the Securities Act or the Exchange Act, any rules or regulations of the Securities and Exchange Commission (“SEC”) promulgated thereunder, or the requirements of applicable state or foreign law relating to authorization, issuance or sale of securities, or until there has been compliance with the provisions of such acts or

rules. The Grantee understands that the Company is under no obligation to register or qualify the Option Shares with the SEC, any state securities commission or any stock exchange to effect such compliance.

10. Lock-Up Agreement; Legends and Trading Policies. The Grantee agrees that, if requested by the Company in connection with an initial public offering, the Grantee will not sell, offer for sale, or otherwise dispose of the Option Shares for such period of time as is determined by the Board, provided that at least a majority of the Company’s directors and officers who hold Shares at such time are similarly bound. The Company may affix to certificates representing Shares issued pursuant to this Agreement any legend that the Committee determines to be necessary or advisable (including to reflect any restrictions to which the Grantee may be subject under a separate agreement with the Company and its Affiliates.). The Company may advise the transfer agent to place a stop order against any legended Shares. To the extent applicable, the Grantee agrees that he or she will not sell, transfer by any means or otherwise dispose of the Option Shares acquired by him except in accordance with Company’s insider trading policy regarding the sale and disposition of securities owned by employees and/or directors of the Company.

11. Non-Transferability of Option. Except as otherwise may be provided by the Committee, this Option may not be transferred in any manner other than by will, by the laws of descent and distribution, or subject to the prior written consent of the Committee (a) by instruments to an inter vivos or testamentary trust in which the Option is passed to beneficiaries upon the death of the Grantee or (b) by gift to Immediate Family, which will include for purposes of this Agreement a family limited partnership or any similar entity which is primarily for the benefit of the Grantee and his or her Immediate Family (provided that any portion of the Option which is intended to be an Incentive Share Option may not be transferred by gift to Immediate Family), and may be exercised during the lifetime of the Grantee only by the Grantee or the Grantee’s legal representative. The terms of this Option will be binding upon the executors, administrators, successors and assigns of the Grantee.

12. Privileges of Share Ownership. The Grantee will not have any of the rights of a shareholder of the Company with respect to any Option Shares (and, for avoidance of doubt, will not be deemed to own any Option Shares for purposes of any employment agreement or otherwise) until the Option Shares are issued to the Grantee and no adjustment will be made for cash distributions in respect of such Option Shares for which the record date is prior to the date upon which such the Grantee or permitted transferee will become the holder of record thereof.

13. Entire Agreement. The Plan is incorporated herein by reference. This Agreement, the Plan, the Exercise Agreement and any such other documents as may be executed in connection with the exercise of this Option constitute the entire agreement and understanding of the parties hereto with respect to the subject matter hereof and supersede all prior understandings and agreements with respect to such subject matter. Any action taken or decision made by the Committee arising out of or in connection with the construction, administration, interpretation or effect of this Agreement will lie within its sole and absolute discretion, as the case may be, and will be final, conclusive and binding on the Grantee and all persons claiming under or through the Grantee.

14. No Obligation to Employ. Nothing in the Plan or this Agreement will confer on the Grantee any right to continue to serve as an employee of, or to continue in any other relationship with, the Company, any Subsidiary or any Affiliate, or limit in any way the right of the Company, any Parent or any Subsidiary or Affiliate to terminate the Grantee’s employment or other relationship at any time, with or without Cause.

15. Notices. Any notice required to be given or delivered to the Company under the terms of this Agreement will be in writing and addressed to the Vice President – Human Resources of the Company at its principal corporate offices in New York, New York (United States of America).

17. Adjustments. In the event of any change in the outstanding shares of the Company after the Grant Date or any other event described in Section 5 of the Plan occurring after the Grant Date, the Board or the Committee will make such equitable substitution or adjustment (including cash payments) as provided for under Section 5 of the Plan in order to preserve the value of the Grantee’s Award.

18. Binding Effect. Any action taken or decision made in good faith by the Committee arising out of or in connection with the construction, administration, interpretation or effect of this Agreement will lie within its sole and absolute discretion, as the case may be, and will be final, conclusive and binding on the Grantee and all persons claiming under or through the Grantee.

19. Section 409A. If any compensation provided by this Agreement may result in the application of Section 409A of the Code, the Company will, in consultation with the Grantee modify the Agreement in the least restrictive manner necessary in order to, where applicable, (a) exclude such compensation from the definition of “deferred compensation” within the meaning of such Section 409A or (b) comply with the provisions of Section 409A, other applicable provision(s) of the Code and/or any rules, regulations or other regulatory guidance issued under such statutory provisions and to make such modifications, in each case, without any diminution in the value of the payments to the Grantee.
