(e) Effect of a Termination of Employment.

(1) If the Participant’s employment with the Company is terminated for any reason prior to the Vesting of any Shares then held by the Participant, such unvested Shares shall thereupon be forfeited immediately by the Participant and returned to the Company.

(2) The Participant hereby (i) irrevocably authorizes the Company to take such actions as may be necessary or appropriate to effectuate a transfer of the record ownership of any such Shares that are unvested and forfeited hereunder, and (ii) agrees to sign such documents and take such actions as the Company may reasonably request to accomplish the transfer or forfeiture of any unvested Shares that are forfeited hereunder.

3. Compliance with Laws and Regulations. This Agreement and the obligations of the Company hereunder shall be subject to all applicable federal and state laws, rules and regulations and to such approvals by any government or regulatory agency as may be required.

4. Legend. Any certificates representing unvested Shares shall be issued in the name of the Participant and held by the Company, and any such certificate (and, to the extent determined by the Company, any other evidence of ownership of unvested Shares) shall contain the following legend:

THE TRANSFERABILITY OF THIS CERTIFICATE AND THE SHARES OF STOCK REPRESENTED HEREBY ARE SUBJECT TO THE TERMS AND CONDITIONS (INCLUDING FORFEITURE) OF A RESTRICTED STOCK AGREEMENT ENTERED INTO BETWEEN THE REGISTERED OWNER AND SPIRIT OF TEXAS BANCSHARES, INC., COPIES OF WHICH ARE ON FILE IN THE SPIRIT OF TEXAS BANCSHARES, INC.

As soon as practicable following the Vesting of any such Shares the Company shall cause a certificate or certificates covering such Shares, without the aforesaid legend, to be issued and delivered to the undersigned, subject to the payment of any withholding taxes due in connection with such Vesting. The Participant shall have the right to vote the Restricted Stock while it is held in custody except as otherwise provided by the Plan. Notwithstanding the foregoing, the Company shall retain custody of all cash, securities or other property distributed by the Company in respect of the Restricted Stock (“Retained Distributions”) subject to the restrictions set forth in this Agreement and such Retained Distributions shall be subject to the same restrictions on terms and conditions as are applicable to such Restricted Stock.

5. Withholding. Upon the Vesting of any shares of Restricted Stock, the Company shall withhold an amount sufficient to satisfy any federal, state and local tax withholding requirements in the form of shares of Stock, unless the Participant makes alternate withholding arrangements with the Company. Unless otherwise required by the Committee, the Company may withhold, or permit a Participant to elect to have withheld from a “Share Payment”, the number of shares of Stock having a Fair Market Value equal to the minimum statutory withholding

requirements but in no event shall such withholding exceed the minimum statutory withholding requirements. Notwithstanding the immediately preceding sentence, the Company, in its discretion, may withhold shares of Stock or permit a Participant to elect to have withheld from a Share Payment, the number of shares of Stock having a Fair Market Value up to, but not in excess of, the maximum statutory withholding requirements, provided that withholding shares of Stock with a Fair Market Value in excess of the minimum statutory withholding requirements will not result in a Stock Incentive otherwise classified as an equity award under ASC Topic 718 to be classified as a liability award under ASC Topic 718. The term “Share Payment” shall mean the issuance or delivery of shares of Stock upon the grant, vesting, exercise or settlement of a Stock Incentive, as the case may be
