Form of Performance-Based Restricted Stock Agreement for Associate (under the Amended and Restated Stock and Incentive Compensation Plan)

(a)Subject to earlier vesting or forfeiture as provided in Paragraph 4 below, the period of restriction (the “Period of Restriction”) applicable to the Award Shares and the Restricted Stock Units is the period from the Award Date through <<end of restriction period>>, and the period during which performance is measured is the period beginning <<beginning of measurement period>> and ending <<end of measurement period>> (the “Performance Period”).  Subject to earlier vesting or forfeiture as provided in Paragraph 4 below, vesting of the Award Shares and Restricted Stock Units shall be determined by (i) the average of the Company’s return on average tangible common equity (“ROATCE”) for each calendar year in the Performance Period compared to the target ROATCE established by the Committee and recommended to, and approved by, the Board on or prior to the Award Date (“ROATCE Target” or “Target”); and (ii) the Company’s total shareholder return (“TSR”) ranking for the Performance Period compared to the TSR for the Peer Group (see Attachment A) over the same period as follows, where vesting in the Award Shares is equal to the number of the Award Shares multiplied by the sum of the vesting percentage in (A) and the vesting percentage in (B) below:  

(b)If the Company’s performance or ranking, as applicable, is above the threshold (<<%>> of Target or above <<rank>> percentile), but less than the maximum (<<%>> of Target or <<rank>> percentile), then the vesting percentage shall be determined by straight line interpolation (rounded, where not otherwise resulting in a whole or half percent, to the next lowest whole or half percent) where the performance or ranking falls between identified tiers (for example, if the TSR ranking is in the <<rank>> percentile, then the vesting percentage is <<%>>).

(c)If the aggregate vesting exceeds 100%, all Award Shares shall be vested and additional shares of the Company’s Stock (“Achievement Shares”) shall be issued to the Participant as provided in Paragraph 4(a), in settlement of the vested Restricted Stock Units, in a number equal to the excess of the aggregate vesting pursuant to this Paragraph 2 over 100% multiplied by the number of Restricted Stock Units (as adjusted by the Committee pursuant to Section 4.4 of the Plan to reflect such events as stock dividends, stock splits, recapitalizations, mergers, consolidations or reorganizations of or by the Company).

Vesting, Payment and Forfeiture.

(a)Vesting and Payment.  Except as otherwise provided pursuant to Paragraphs 4(b) and 4(c), all determinations regarding vesting and entitlement to the Award Shares, the Restricted Stock Units and any Achievement Shares under this Paragraph 4(a) shall be made and certified to in writing by the Committee, and all such shares and units shall be settled or issued, as applicable, during the 2-1/2 month period beginning on January 1 and ending on March 15 following the end of the Performance Period (the “Designated Settlement Period”). Once vested, the restrictions applicable to the vested Award Shares automatically terminate, and the vested Award Shares shall be free of restrictions and freely transferable. Once issued, the Achievement Shares shall be unrestricted, 100% vested and freely transferable as of their date of issuance and shall have full voting rights and otherwise possess all rights of Shares from their date of issuance. Subject to earlier vesting or forfeiture under Paragraphs 4(b) and 4(c), any Award Shares and Restricted Stock Units that are not, based on the Committee’s determination, earned

based on performance during the Performance Period, shall be cancelled and forfeited as of the last day of the Performance Period.

(b)Termination of Employment and Forfeiture.  Except as provided otherwise in this Paragraph 4(b) for a Qualifying Termination and Paragraph 4(c) in the event of a Vesting Acceleration Event after <<date>> and before the last day of the Performance Period, any termination of employment of the Participant by the Company or by the Participant before the last day of the Performance Period shall result in the immediate forfeiture of all Award Shares and Restricted Stock Units and no Achievement Shares shall be issued.  Notwithstanding any other provision of this Agreement, any termination of the Participant’s employment for Cause prior to the certification and settlement and issuance of Shares under Paragraph 4(a) shall result in the immediate forfeiture of all Award Shares and Restricted Stock Units and no Achievement Shares shall be issued.  In the event of a Qualifying Termination of the Participant, a portion of the Award Shares and Restricted Stock Units, respectively, shall be immediately forfeited (the “Forfeited Portions”) as determined in the following sentence and the remaining Award Shares and Restricted Stock Units (the “Remaining Portions”) shall remain subject to the provisions of this Agreement, including, but not limited to (i) the performance vesting and calculation provisions under Paragraph 2, (ii) the restrictions on transfer provided under Paragraph 3, and (iii) the payment provisions in Paragraph 4(a).  The “Forfeited Portions” shall be determined by multiplying the number of Award Shares and Restricted Stock Units, respectively, by a fraction (not to exceed one), the numerator of which is the number of complete calendar months from and including the date of the Qualifying Termination until the end of the Performance Period, and the denominator of which is <<#>>.  If the Participant’s death or Disability occurs before the last day of the Performance Period but after a Qualifying Termination, then the provisions of Paragraph 4(c) shall apply to the Remaining Portions (except for the time-weighted pro-ration calculation which will have already been applied).  

(c)Vesting Acceleration Event.  Subject to earlier forfeiture as otherwise provided in Paragraph 4(b), in the event a Vesting Acceleration Event occurs while the Participant is an employee of the Company or one of its Subsidiaries, after <<date>> and before the last day of the Performance Period, then the average ROATCE and the TSR of the Company and the TSR of the Peer Group shall be determined through the end of the calendar quarter ending on or prior to the date of the first such Vesting Acceleration Event and the vesting provisions set forth in Paragraph 2 shall be applied to a time-weighted portion of the Award Shares (determined by multiplying the number of Award Shares by a fraction (not to exceed one), the numerator of which is the number of complete calendar months from the beginning of the Performance Period to and including the Vesting Acceleration Event, and the denominator of which is <<#>>) based on such ROATCE and TSR results. For purposes of this calculation, average ROATCE shall be calculated using the number of complete calendar quarters from the beginning of the Performance Period to the Vesting Acceleration Event, except that complete calendar years shall be used if such measurement period consists of one or two complete calendar years.  In such event, the Period of Restriction shall end, the restrictions applicable to the Award Shares shall automatically terminate, and the Award Shares shall be free of restrictions and freely transferable, all to the extent of the vested Award Shares as so determined, on the date of such Vesting Acceleration Event. In such event, any balance of the Award Shares and Restricted Stock Units which are not vested shall be immediately forfeited.  If the aggregate time-weighted vesting exceeds 100%, Achievement Shares shall be issued to the Participant, in settlement of the vested Restricted Stock Units, in a number equal to the excess of the aggregate time-weighted vesting pursuant to this Paragraph 4(c) over 100% multiplied by the number of Restricted Stock Units (as adjusted by the Committee pursuant to Section 4.4 of the Plan to reflect such events as stock dividends, stock splits, recapitalizations, mergers, consolidations or reorganizations of or by the Company).  The Achievement Shares

shall be unrestricted, 100% vested and freely transferable as of their date of issuance and shall have full voting rights and otherwise possess all rights of Shares from their date of issuance. All determinations regarding vesting and entitlement to the Award Shares, the Restricted Stock Units and any Achievement Shares under this Paragraph 4(c) shall be made and certified to in writing by the Committee, and all such shares and units shall be settled or issued, as applicable, within 2-1/2 months following the date of the Vesting Acceleration Event.

The Company shall issue the Award Shares and Achievement Shares, if any, either: (i) in certificate form as provided in Paragraph 6(b) below; or (ii) in book entry form, registered in the name of the Participant with notations regarding any applicable restrictions on transfer imposed under this Agreement.

Any certificates representing Award Shares shall be held by the Company until such time as the restrictions hereunder lapse and such shares become transferable, or are forfeited hereunder.  Any Award Shares issued in book entry form shall be subject to the following legend and any certificates representing the Award Shares shall bear the following legend, until such time as the restrictions hereunder lapse and such shares become transferable:

Promptly after the lapse of the restrictions with respect to any of the Award Shares, the Company shall, as applicable, either remove the notations on the Award Shares issued in book entry form as to which the restrictions have lapsed or deliver to the Participant a certificate or certificates evidencing the number of Award Shares as to which the restrictions have lapsed.

The Committee may require, concurrently with the Participant’s electronic acceptance of this Agreement, the Participant to submit to the Company an executed stock power, in blank, with respect to the Award Shares or Achievement Shares.  The Participant, by acceptance of the Award, shall be deemed to appoint, and does so appoint, the Company and each of its authorized representatives as the Participant’s attorney(s) in fact to effect any transfer of forfeited shares (or shares otherwise reacquired or withheld by the Company hereunder) to the Company as may be required pursuant to the Plan or this Agreement and to execute such documents as the Company or such representatives deem necessary or advisable in connection with any such transfer.

(a)It is intended that any right or benefit which is provided pursuant to or in connection with this Award which is considered to be nonqualified deferred compensation subject to Section 409A (“Section 409A”) of the Code (a “409A benefit”) shall be provided and paid in a manner, and at such time (i.e., at the applicable payment event described herein if a Section 409A payment event or otherwise at the first Section 409A payment event thereafter consisting of a fixed time (here, the Designated Settlement Period for cash dividends on the Award Shares and for Achievement Shares), a Section 409A disability, a Section 409A separation from service (as described below), or a Section 409A change with respect to the Participant in the ownership or effective control of the Company or in the ownership of a substantial portion of its assets of the Company and including, in the discretion of the Committee or its delegate, any applicable Section 409A de minimis limited cashout payment permitted under Treasury Reg. Section 1.409A-3(j)(4)(v)) and in such form, as complies with the applicable requirements of Section 409A to avoid the unfavorable tax consequences provided therein for non-compliance.  Consistent with Treas. Reg. Section 1.409A-3(d), payment of all or any portion of any 409A benefit shall be treated as paid in the Designated Settlement Period so long as all or any portion of such payment is made during the Designated Settlement Period or such later date within the same taxable year that contains the Designated Settlement Period.  This Agreement is intended to be administered, interpreted and construed in accordance with the applicable requirements of Section 409A.  Notwithstanding the foregoing, the Participant and his or her successor in interest shall be solely responsible and liable for the satisfaction of all taxes and penalties that may be imposed on the Participant or his or her successor in interest in connection with this Agreement (including any taxes and penalties under Section 409A); and neither the Company nor any of its affiliates shall have any obligation to indemnify or otherwise hold the Participant or his or her successor in interest harmless from any or all of such taxes or penalties.  

(b)Except as permitted under Section 409A, any 409A benefit payable to the Participant or for his or her benefit with respect to the Award may not be reduced by, or offset against, any amount owing by the Participant to the Company or any of its affiliates.

(c)In the event entitlement to payment of any 409A benefit occurs due to termination or cessation of employment, termination or cessation of employment shall be read to mean “separation from service” (within the meaning of Section 409A and as applicable to the Company and its affiliates).  Where entitlement to payment occurs by reason of such termination or cessation of employment and the Participant is a “specified employee” (within the meaning of Section 409A, as applicable to the Company and its affiliates and using the identification methodology selected by the Company from time to time in accordance with Section 409A) on the date of his or her “separation from service”, then payment of such 409A benefit shall be delayed (without interest) until the first business day after the end of the six month delay period required under Section 409A or, if earlier, after the Participant’s death.  In determining separation from service, separation from service is determined based on the “Separation from Service” definition in the

Trustmark Corporation Deferred Compensation Plan (as in effect on <<date>>), which provides, in part, that in determining separation from service as an employee, separation from service occurs when it is reasonably anticipated that no further services would be performed after that date or that the level of services the Participant would perform after that date (whether as an employee or independent contractor) would permanently decrease to less than 50% of the average level of bona fide services performed over the immediately preceding <<months>> month period.
