WHEREAS, the Company has adopted the Prosperity Bancshares, Inc. 2020 Stock Incentive Plan, as the same may be amended from time to
time (the “Plan”) pursuant to which awards of Restricted Stock may be granted; and 
 WHEREAS, the Committee has
determined that it is in the best interests of the Company and its shareholders to grant the award of Restricted Stock provided for herein. 
 NOW,
THEREFORE, in consideration of the premises, the mutual covenants contained herein, and other good and valuable consideration, the parties hereto agree as follows: 

1. Grant of Restricted Stock. Pursuant to Section 7.2 of the Plan, the Company hereby issues to the Grantee on the Grant Date a
Restricted Award consisting of all right, title and interest in [NUMBER] shares of Common Stock of the Company, par value $1.00 per share (the “Restricted Stock”), on the terms and conditions and subject to the restrictions set
forth in this Agreement and the Plan. Capitalized terms that are used but not defined herein have the meaning ascribed to them in the Plan. 

2. Consideration. The grant of the Restricted Stock is made in consideration of the services to be rendered by the Grantee to the
Company. 
 3. Restricted Period; Vesting. 

3.1 Except as otherwise provided herein, provided that the Grantee remains in Continuous Service through the applicable vesting
date[, and further provided that any additional conditions and performance goals set forth in Schedule I have been satisfied], the Restricted Stock will vest in accordance with the following schedule: 

 

			
	Vesting Date	  	Shares of Common Stock
	[VESTING DATE]	  	[NUMBER OR PERCENTAGE OF SHARES THAT VEST ON THE VESTING DATE]
	[VESTING DATE]	  	[NUMBER OR PERCENTAGE OF SHARES THAT VEST ON THE VESTING DATE]


 The period over which the Restricted Stock vests is referred to as the
“Restricted Period”. 











 3.2 Except as otherwise provided herein or in the Plan, if the
Grantee’s Continuous Service terminates for any reason at any time before all of his or her Restricted Stock has vested, the Grantee’s then-unvested Restricted Stock shall be automatically and immediately forfeited for no consideration
upon such termination of Continuous Service and neither the Company nor any Affiliate shall have any further obligations to the Grantee under this Agreement. Notwithstanding the immediately preceding sentence, in the event of the Grantee’s
death or if the Grantee’s Continuous Service is terminated by the Company or an Affiliate as a result of the Grantee’s Disability, 100% of the then-unvested Restricted Stock shall vest as of the date of such termination. 

3.3 Unless otherwise determined by the Committee at the time of a Change in Control, a Change in Control shall have no effect
on the Restricted Stock. 
 4. Restrictions. Subject to any exceptions set forth in this Agreement or the Plan, during the Restricted
Period, the Restricted Stock or the rights relating thereto may not be assigned, alienated, pledged, attached, sold, hypothecated, exchanged or otherwise transferred or encumbered by the Grantee. Any attempt to assign, alienate, pledge, attach,
sell, hypothecate, exchange or otherwise transfer or encumber the Restricted Stock or the rights relating thereto during the Restricted Period shall be wholly ineffective and, if any such attempt is made, the Restricted Stock will be automatically
and immediately forfeited by the Grantee and all of the Grantee’s rights to such shares shall automatically and immediately terminate without any consideration therefor. 

5. Rights as Shareholder; Dividends. 

5.1 The Grantee shall be the record owner of the Restricted Stock until the shares of Common Stock are sold or otherwise
disposed of, and shall be entitled to all of the rights of a shareholder of the Company including, without limitation, the right to vote such shares and receive all dividends or other distributions paid with respect to such shares. The Grantee shall
be entitled to dividends paid or declared on Restricted Stock for which the record date is on or after the date such Restricted Stock has been issued in the Grantee’s name and shall be entitled to receive such dividends at the same time
dividends are paid to holders of Common Stock generally. 
 5.2 The Company may issue stock certificates or evidence the
Grantee’s interest by using a restricted book entry account with the Company’s transfer agent. Physical possession or custody of any stock certificates that are issued may be retained by the Company until such time as the Restricted Stock
vests. 
 5.3 If the Grantee forfeits any rights he or she has under this Agreement, the Grantee shall, on the date of such
forfeiture, no longer have any rights as a shareholder with respect to the then-unvested Restricted Stock and shall no longer be entitled to vote or receive dividends on such shares. 

6. No Right to Continued Service. Neither the Plan nor this Agreement shall confer upon the Grantee any right to be retained in any
position, as an Employee, Consultant or Director. Further, nothing in the Plan or this Agreement shall be construed to limit the discretion of the Company to terminate the Grantee’s Continuous Service at any time for any reason or for no
reason.

structure of the Company, if required, the shares of Common Stock shall be adjusted or terminated in any manner as contemplated by Section 11 of the Plan. 

8. Tax Liability and Withholding. 

8.1 The Grantee shall be required to pay to the Company, and the Company shall have the right to deduct from any compensation
paid to the Grantee pursuant to the Plan, the amount of any required withholding taxes in respect of the Restricted Stock and to take all such other action as the Committee deems necessary to satisfy all obligations for the payment of such
withholding taxes. The Committee may permit the Grantee to satisfy any federal, state or local tax withholding obligation by any of the following means, or by a combination of such means: 

(a) tendering a cash payment. 

(b) authorizing the Company to withhold shares of Common Stock from the shares of Common Stock otherwise issuable or
deliverable to the Grantee as a result of the vesting of the Restricted Stock; provided, however, that no shares of Common Stock shall be withheld with a value exceeding the maximum amount of tax required to be withheld by law. 

(c) delivering to the Company previously owned and unencumbered shares of Common Stock. 

8.2 Notwithstanding any action the Company takes with respect to any or all income tax, payroll tax, or other tax-related withholding (“Tax-Related Items”), the ultimate liability for all Tax-Related Items is and remains the
Grantee’s responsibility and none of the Company, the Board or any agents of either of the foregoing (a) make any representation or undertakings regarding the treatment of any Tax-Related Items in
connection with the grant or vesting of the Restricted Stock (or dividends or distributions with respect thereto) or the subsequent sale of any shares; and (b) commit to structure the Restricted Stock (or dividends or distributions with respect
thereto) to reduce or eliminate the Grantee’s liability for Tax-Related Items. 
 9.
Section 83(b) Election. The Grantee may make an election under Code Section 83(b) (a “Section 83(b) Election”) with respect to the Restricted Stock. Any such election must be made
within thirty (30) days after the Grant Date. If the Grantee elects to make a Section 83(b) Election, the Grantee shall promptly provide the Company with payment in such form as is acceptable to the Company in the amount of taxes (as
determined by the Company) resulting from the Section 83(b) Election and with a copy of an executed version and satisfactory evidence of the filing of the executed Section 83(b) Election with the Internal Revenue Service. The Grantee
agrees to assume full responsibility for ensuring that the Section 83(b) Election is actually and timely filed with the Internal Revenue Service and for all tax consequences resulting from the Section 83(b) Election.

 18. Discretionary Nature of Plan. The Plan is discretionary and may be amended,
cancelled or terminated by the Company at any time, in its discretion. The grant of the Restricted Stock in this Agreement does not create any contractual right or other right to receive any Restricted Stock or other Awards in the future. Future
Awards, if any, will be at the sole discretion of the Company. Any amendment, modification, or termination of the Plan shall not constitute a change or impairment of the terms and conditions of the Grantee’s employment with or other service to
the Company or its Affiliates. 
 19. Amendment. The Committee has the right to amend, alter, suspend, discontinue or cancel the
Restricted Stock, prospectively or retroactively; provided, that, no such amendment shall adversely affect the Grantee’s material rights under this Agreement without the Grantee’s consent. 

20. No Impact on Other Benefits. The value of the Grantee’s Restricted Stock is not part of his or her normal or expected
compensation for purposes of calculating any severance, retirement, welfare, insurance or similar employee benefit unless expressly provided for by the terms of the applicable plan or pursuant to applicable law. 

21. Counterparts. This Agreement may be executed in counterparts, each of which shall be deemed an original but all of which together
will constitute one and the same instrument. Counterpart signature pages to this Agreement transmitted by facsimile transmission, by electronic mail in portable document format (.pdf), or by any other electronic means intended to preserve the
original graphic and pictorial appearance of a document, will have the same effect as physical delivery of the paper document bearing an original signature.

the terms and provisions thereof, and accepts the Restricted Stock subject to all of the terms and conditions of the Plan and this Agreement. The Grantee acknowledges that there may be adverse tax consequences upon the grant or vesting of the
