The Participant has been granted a Performance Based Restricted Stock Unit Award (the “Award”) by Chubb Limited (the “Company”) under the Chubb Limited 2016 Long-Term Incentive Plan (the “Plan”). The Covered Performance Units and Premium Performance Units granted pursuant to this Award shall be subject to the following Performance Based Restricted Stock Unit Award terms (the “Terms”):

1.Terms of Award. Subject to the following Terms, the Participant has been granted the right to receive shares of Stock of the Company (“Units”) as of the Delivery Date. Each “Unit” represents the right to receive one share of Stock. The following words and phrases used in these Terms shall have the meanings set forth in this paragraph 1:

(a)The “Participant” is the individual recipient of the Performance Based Restricted Stock Unit Award on the specified Grant Date.

(b)The “Grant Date” is [Insert Date].

(c)The “Commencement Date” is [Insert Date].

(d)The “Delivery Date” shall be the end of the Restricted Period with respect to the applicable Units.

(e)The number of “Covered Performance Units” shall be that number of Units awarded to the Participant on the Grant Date as reflected in the corporate records and shown in the Record-Keeping System in the Participant’s individual account records.

(f)The number of “Premium Performance Units” shall be that number of Units awarded to the Participant on the Grant Date as reflected in the corporate records and shown in the Record-Keeping System in the Participant’s individual account records.

Other words and phrases used in these Terms are defined pursuant to paragraph 13 or elsewhere in these Terms.

2.Restricted Period for Covered Performance Units. Subject to the limitations of these Terms, the “Restricted Period” for the Covered Performance Units shall begin on the Grant Date and end on the Vesting Date as described below (but only if the Date of Termination has not occurred before the Vesting Date):

(a)If the Cumulative Performance of the Company during the Performance Period is equal to 50% or greater, the Restricted Period shall end for any Covered Performance Units on the later of the three-year anniversary of the Grant Date and the date the Committee certifies that the requisite Cumulative Performance has been achieved during the Performance Period (such later date referred to as the “Vesting Date”). If the Cumulative

Performance of the Company during the Performance Period is less than 50%, the Restricted Period shall end with respect to a number of the Covered Performance Units determined by multiplying the total number of Covered Performance Units by the Performance Percentage (as determined below) on the Vesting Date.

(b)The “Performance Percentage” will be determined based on the achievement of the Cumulative Performance over the Performance Period in accordance with the following schedule:

(c)For the avoidance of doubt, the Restricted Period shall end only on or after the Committee’s certification that the Cumulative Performance for the Performance Period has been completed. Any Covered Performance Units that have not vested as of the end of the Restricted Period shall be forfeited by the Participant as of the Vesting Date.

3.Retirement. If the Participant’s Date of Termination occurs because of Retirement, then for any Covered Performance Units and any Premium Performance Units as to which the Restricted Period has not otherwise ended prior to the Date of Termination, the Participant shall become vested and the Restricted Period shall end for any Covered Performance Units if and when the terms of paragraph 2 are satisfied with respect to such Covered Performance Units and for any Premium Performance Units if and when the terms of paragraph 7 are satisfied with respect to such Premium Performance Units, in each case, determined as though the Participant had remained employed and the Date of Termination had not occurred prior to the end of any applicable Restricted Period for purposes of these Terms. Notwithstanding the foregoing, if the Participant’s Date of Termination on account of Retirement occurs (a) prior to the six-month anniversary of the Grant Date without appropriate notice as determined by the Committee and (b) prior to the Vesting Date, the Committee may cause the Participant to forfeit any or all Premium Performance Units as of the Date of Termination.

4.Death, Long-Term Disability and Change in Control. Notwithstanding the provisions of paragraph 2, the Restricted Period for Covered Performance Units shall end prior to the date specified in paragraph 2 to the extent set forth below:

(a)For Covered Performance Units as to which the Restricted Period has not ended prior to the Date of Termination, the Restricted Period for such Covered Performance Units shall end upon the Participant’s Date of Termination, and the Covered Performance Units shall fully vest upon the Date of Termination, if the Date of Termination occurs by reason of the Participant’s death or Long-Term Disability.

(b)For Covered Performance Units as to which the Restricted Period has not ended prior to the date of a Change in Control, the Restricted Period for such Covered Performance Units shall end upon a Change in Control, and the Covered Performance Units shall vest upon the Change in Control, provided that such Change in Control occurs on or before the Date of Termination.

5.Restricted Period for Premium Performance Units. Subject to the limitations of these Terms, the Restricted Period for the Premium Performance Units shall begin on the Grant Date and end on the Vesting Date (but only if the Date of Termination has not occurred before the Vesting Date) as follows:

(b)The “Premium Award Performance Percentage” will be determined based on the achievement of the Cumulative Performance over the Performance Period in accordance with the following schedule:

(c)For the avoidance of doubt, the Restricted Period shall end only on or after the Committee’s certification that the Cumulative Performance for the Performance Period has been completed. Any Premium Performance Units that have not vested as of the end of the Restricted Period shall be forfeited by the Participant as of the Vesting Date. Except as provided in paragraph 3 for a Date of Termination that occurs because of Retirement, the Participant shall not be entitled to vesting of any Premium Performance Units if the Date of Termination occurs before the Vesting Date for any reason.

6.Transfer and Forfeiture of Shares. Except as otherwise determined by the Committee and as provided in paragraphs 3, 4 and 5 above, the Participant shall forfeit any Covered Performance Units and Premium Performance Units as of the Date of Termination, if such Date of Termination occurs prior to the Vesting Date. Any vested Units which are not subject to a Deferral Election shall be delivered to the Participant in the form of Stock free of all restrictions at or within 30 days after the Delivery Date, but in no event later than March 15 of the year following the Vesting Date; provided, however, if such delivery is contingent on the Participant's execution of a release in accordance with subparagraph 12(l) and the applicable 30-day period begins in one taxable year and ends in a second taxable year, the Units shall be delivered in the second taxable year. After delivery of a share of Stock for a Unit, the Unit shall

have no further force or effect. Notwithstanding anything in this Agreement to the contrary, to the extent a Unit granted under this Agreement is subject to a Deferral Election, then to the extent not forfeited under this Agreement, such Unit shall be delivered to the Participant at the time and in the form provided under the terms of the Chubb Deferred Stock Unit Plan.

7.Withholding. All deliveries and distributions and the vesting of shares of stock under these Terms are subject to withholding of all applicable taxes. At the election of the Participant, and subject to such rules and limitations as may be established by the Committee from time to time and to the extent permitted under Code Section 409A, such withholding obligations may be satisfied through the surrender of shares of Stock which the Participant already owns, or to which the Participant is otherwise entitled under the Plan. Notwithstanding the foregoing, the Committee has the authority to make the necessary elections to ensure appropriate taxes are withheld.1

8.Transferability. Except as otherwise provided by the Committee, awards under these Terms may not be sold, assigned, transferred, pledged or otherwise encumbered prior to vesting and delivery.

9.Dividend Equivalents. The Participant shall be permitted to receive cash payments equal to the dividend equivalents and distributions paid on shares of Stock to the same extent as if each Unit was a share of Stock, and those shares were not subject to the restrictions imposed by these Terms and the Plan; provided, however, that no dividend equivalents or distributions shall be payable to or for the benefit of the Participant with respect to record dates for such dividend equivalents or distributions occurring on or after the date, if any, on which the Participant has received a share of Stock in exchange for a Unit or has forfeited the Units. Dividend equivalent payments made under this paragraph 9 with respect to record dates on or after the Grant Date for such Units but prior to the end of the Restricted Period for such Units shall be accumulated and distributed to the Participant on the date that the Restricted Period ends with respect to the Units pursuant to which such dividend equivalent was paid, unless such dividend equivalents are subject to a Deferral Election. Notwithstanding anything in this Agreement to the contrary, to the extent a dividend equivalent payable under this Agreement is subject to a Deferral Election, such dividend equivalent shall be paid to the Participant at the time and in the form provided under the terms of the Chubb Deferred Stock Unit Plan.

10.Voting. The Participant shall not be a shareholder of record with respect to the Units and shall have no voting rights with respect to the Units during the Restricted Period.

The Committee, in its discretion, may adjust the reported tangible book value for the Company or the Peer Companies for the Performance Period.

The Committee shall make or shall cause to be made such appropriate adjustments to the calculation of total shareholder return for such entity (including adjusting the average at the beginning of the Performance Period) as shall be necessary or appropriate to avoid an artificial increase or decrease in such return as a result of a stock split (including a reverse stock split), recapitalization, or other event affecting the capital structure of such entity.

Participant agrees that the foregoing rights and remedies of Company shall be in addition to, and not in lieu of, any other remedies available to the Company at law or in equity.

(d)The Non-Solicit Period will be tolled for any period during which Participant is in violation of any provision of this paragraph 18.

19.Not An Employment Contract. This Award and these Terms will not confer on the Participant any right with respect to continuance of employment or other service with the Company or any Subsidiary, nor will it interfere in any way with any right the Company or any Subsidiary would otherwise have to terminate or modify the terms of such Participant’s employment or other service at any time. These Terms are not intended to and do not supersede the terms of any previous agreement between the Participant and the Company or a Subsidiary.

20.Notices. Any written notices provided for in these Terms or the Plan shall be in writing and shall be deemed sufficiently given if either hand delivered or if sent by fax or overnight courier, or by postage paid first class mail.

Notices shall be directed, if to the Participant, at the Participant’s address indicated by the Company’s records, or if to the Company, at the Company’s principal executive office.

21.Fractional Shares. In lieu of issuing a fraction of a share, resulting from an adjustment of this Award pursuant to paragraph 5.2(f) of the Plan or otherwise, the Company will be entitled to pay to the Participant an amount equal to the fair market value of such fractional share.

22.Amendment. These Terms may be amended in accordance with the provisions of the Plan, and may otherwise be amended by written agreement of the Participant and the Company without the consent of any other person.

23.409A Compliance. These Terms are intended to be interpreted, operated, and administered in a manner so as not to subject the Participant to the assessment of additional taxes or interest under Code section 409A, and these Terms may be amended as the Company, in its sole discretion, determines is necessary and appropriate to avoid the application of any such taxes or interest.

IN WITNESS WHEREOF, the Company has caused these presents to be executed in its name and on its behalf, all as of the Grant Date.
