FORM OF NONQUALIFIED STOCK OPTION AGREEMENT

 Exhibit 4.4 
 METROCORP BANCSHARES, INC. 
 NONQUALIFIED STOCK OPTION AGREEMENT

 This Nonqualified Stock Option Agreement (“Option Agreement”) is between MetroCorp Bancshares, Inc., a Texas
corporation (the “Company”), and
                                         
                    (“Optionee”), who agree as follows: 
 Section 1. Introduction. The Company has heretofore adopted the Amended and Restated MetroCorp Bancshares, Inc. 2007 Stock Awards and Incentive Plan (the “Plan”) for the purpose of
providing a means whereby those employees, directors and consultants, upon whom the responsibilities of the successful administration and management of the Company and its Affiliates (as defined in the Plan) rest, and whose present and potential
contributions to the welfare of the Company and its Affiliates are of importance, can acquire and maintain stock ownership, thereby strengthening their concern for the welfare of the Company and its Affiliates and their desire to remain in the
Company’s and its Affiliates’ employ. The Company, acting through the Committee (as defined in the Plan), has determined that its interests will be advanced by the issuance to Optionee of a nonqualified stock option under the Plan.

 Section 2. Option. Subject to the terms and conditions contained herein, the Company hereby irrevocably grants to
Optionee the right and option (“Option”) to purchase from the Company                      shares of the Company’s common
stock, $1.00 par value (“Common Stock”), at a price of $                 per share. 

Section 3. Option Period. The Option herein granted may be exercised by Optionee in whole or in part at any time during a ten
year period (the “Option Period”) beginning on
                                        
(the “Date of Grant”), subject to the limitation that said Option shall not be exercisable for more than a percentage of the aggregate number of shares offered by this Option determined by the number of full years of employment with the
Company or its Affiliates from the Date of Grant to the date of such exercise, in accordance with the following schedule: 
  

			
	 Number of

Full Years
	 	 Percentage of

Shares Purchasable

		 	

 Notwithstanding anything in this Option Agreement to the contrary, the Committee, in its sole discretion, may waive the
foregoing schedule of vesting and upon written notice to Optionee, accelerate the earliest date or dates on which any of the Options granted hereunder are exercisable. 
 Section 4. Procedure for Exercise. The Option herein granted may be exercised by the delivery by Optionee of written notice to the Secretary of the Company setting forth the number of shares
of Common Stock with respect to which the Option is being exercised. The notice shall be accompanied by, at the election of Optionee, (i) cash, cashier’s check, bank draft, or postal or 

  
 -1-

 express money order payable to the order of the Company, (ii) certificates representing shares of
Common Stock theretofore owned by Optionee duly endorsed for transfer to the Company, or (iii) any combination of the preceding, equal in value to the aggregate exercise price. Notice may also be delivered by telecopy provided that the exercise
price of such shares is received by the Company via wire transfer on the same day the telecopy transmission is received by the Company. The notice shall specify the address to which the certificates for such shares are to be mailed. This Option
shall be deemed to have been exercised immediately prior to the close of business on the date (i) written notice of such exercise and (ii) payment in full of the exercise price for the number of share for which Options are being exercised,
are both received by the Company and Optionee shall be treated for all purposes as the record holder of such shares of Common Stock as of such date. 
 As promptly as practicable after receipt of such written notice and payment, the Company shall deliver to Optionee certificates for the number of shares with respect to which such Option has been so
exercised, issued in Optionee’s name or such other name as Optionee directs; provided, however, that such delivery shall be deemed effected for all purposes when a stock transfer agent of the Company shall have deposited such certificates in
the United States mail, addressed to Optionee at the address specified pursuant to this Section 4. 
 Section 5.
Termination of Employment. If, for any reason other than death or disability, Optionee ceases to be employed by the Company or its Affiliates or ceases to serve as a director or consultant, the Option may be exercised (to the extent Optionee
would have been entitled to do so at the date of termination of employment or cessation of serving as a director or consultant) during a three month period after such date (after which period the Option shall expire), but in no event may the Option
be exercised after the expiration of the Option Period. To the extent the Option is not yet exercisable pursuant to Section 3 hereof on the date of such termination of employment, the Option shall terminate on the date of termination of
employment. Notwithstanding the foregoing, if Optionee’s employment is terminated because of Optionee’s theft or embezzlement from the Company, disclosure of trade secrets of the Company or the commission of a willful, felonious act while
in the employment of the Company (such reasons shall hereinafter be collectively referred to as “for cause”), then the Option or unexercised portion thereof shall expire upon such termination of employment. 

In the event that Optionee dies or is determined to be disabled while Optionee is employed by the Company or while Optionee serves as a
director or consultant, the Option may be exercised (to the extent Optionee would have been entitled to do so at the date of death or the determination of disability) at any time and from time to time, within a one-year period after such death or
determination of disability, by Optionee, the guardian of Optionee’s estate, the executor or administrator of Optionee’s estate or by the person or persons to whom Optionee’s rights under this Option Agreement shall pass by will or
the laws of descent and distribution (after which period the Option shall expire), but in no event may the Option be exercised after the expiration of the Option Period. To the extent the Option is not yet exercisable pursuant to Section 3
hereof on the date of such death or disability, the Option shall terminate on the date of death or disability. Optionee shall be deemed to be disabled if, in the opinion of a physician selected by the Committee, Optionee is incapable of performing
services for the Company of the kind Optionee was performing at the time the disability occurred by reason of any medically determinable physical or mental impairment which can be expected to result in death or to be of long, continued and
indefinite duration. The date of determination of disability for purposes hereof shall be the date of such determination by such physician.

 Section 6. Transferability. This Option shall not be transferable by Optionee
otherwise than by Optionee’s will or by the laws of descent and distribution. During the lifetime of Optionee, the Option shall be exercisable only by Optionee or his authorized legal representative. Any heir or legatee of Optionee shall take
rights herein granted subject to the terms and conditions hereof. No such transfer of this Option Agreement to heirs or legatees of Optionee shall be effective to bind the Company unless the Company shall have been furnished with written notice
thereof and a copy of such evidence as the Committee may deem necessary to establish the validity of the transfer and the acceptance by the transferee or transferees of the terms and conditions hereof. 

Section 7. No Rights as Shareholder. Optionee shall have no rights as a shareholder with respect to any shares of Common
Stock covered by this Option Agreement until the Option is exercised by written notice and accompanied by payment as provided in Section 4 of this Option Agreement. 
 Section 8. Extraordinary Corporate Transactions. The existence of outstanding Options shall not affect in any way the right or power of the Company or its shareholders to make or authorize any
or all adjustments, recapitalizations, reorganizations, exchanges or other changes in the Company’s capital structure or its business, or any merger or consolidation of the Company, or any issuance of Common Stock or other securities or
subscription rights thereto, or any issuance of bonds, debentures, preferred or prior preference stock ahead of or affecting the Common Stock or the rights thereof, or the dissolution or liquidation of the Company, or any sale or transfer of all or
any part of its assets or business, or any other corporate act or proceedings, whether of a similar character or otherwise. If the Company undergoes a “Change of Control” (as defined in the Plan) or other corporate reorganization described
in Paragraph XII of the Plan, the Options granted hereunder shall be governed by Paragraph XII of the Plan. 
 Section 9.
Changes in Capital Structure. Upon the occurrence of an event described in Section XII(a) of the Plan, this Option shall be adjusted in accordance with Section XII(a) of the Plan. 

Section 10. Compliance With Securities Laws. Upon the acquisition of any shares pursuant to the exercise of the Option herein
granted, Optionee (or any person acting under Section 6) will enter into such written representations, warranties and agreements as the Company may reasonably request in order to comply with applicable securities laws or with this Option
Agreement. 
 Section 11. Compliance With Laws. Notwithstanding any of the other provisions hereof, Optionee agrees
that he or she will not exercise the Option granted hereby, and that the Company will not be obligated to issue any shares pursuant to this Option Agreement, if the exercise of the Option or the issuance of such shares of Common Stock would
constitute a violation by Optionee or by the Company of any provision of any law or regulation of any governmental authority. 

  
 -3-

 Section 12. Withholding of Tax. To the extent that the exercise of this Option
or the disposition of shares of Common Stock acquired by exercise of this Option results in compensation income to Optionee for federal or state income tax purposes, Optionee shall pay to the Company at the time of such exercise or disposition such
amount of money as the Company may require to meet its obligation under applicable tax laws or regulations and, if Optionee fails to do so, the Company is authorized to withhold from any cash remuneration then or thereafter payable to Optionee, any
tax required to be withheld by reason of such resulting compensation income or Company may otherwise refuse to issue or transfer any shares otherwise required to be issued or transferred pursuant to the terms hereof. Payment of the withholding tax
by Optionee shall be made in accordance with Paragraph XIV(f) of the Plan. 
 Section 13. No Right to Employment or
Directorship. Optionee shall be considered to be in the employment of the Company or its Affiliates or in service as a director or consultant so long as he or she remains an employee, director or consultant of the Company or its Affiliates. Any
questions as to whether and when there has been a termination of such employment or service as a director or consultant and the cause of such termination shall be determined by the Committee, and its determination shall be final. Nothing contained
herein shall be construed as conferring upon Optionee the right to continue in the employ of the Company or its Affiliates or to continue service as a director or consultant, nor shall anything contained herein be construed or interpreted to limit
the “employment at will” relationship between Optionee and the Company or its Affiliates. 
 Section 14.
Resolution of Disputes. As a condition of the granting of the Option hereby, Optionee and Optionee’s heirs, personal representatives and successors agree that any dispute or disagreement which may arise hereunder shall be determined by
the Committee in its sole discretion and judgment, and that any such determination and any interpretation by the Committee of the terms of this Option Agreement shall be final and shall be binding and conclusive, for all purposes, upon the Company,
Optionee, and Optionee’s heirs, personal representatives and successors. 
 Section 15. Legends on Certificate.
The certificates representing the shares of Common Stock purchased by exercise of the Option will be stamped or otherwise imprinted with legends in such form as the Company or its counsel may require with respect to any applicable restrictions on
sale or transfer and the stock transfer records of the Company will reflect stop-transfer instructions with respect to such shares. 
 Section 16. Notices. Every notice hereunder shall be in writing and shall be given by registered or certified mail. All notices of the exercise of any Option hereunder shall be directed to
MetroCorp Bancshares, Inc., 9600 Bellaire Boulevard, Suite 252, Houston, Texas 77036, Attention: Secretary. Any notice given by the Company to Optionee directed to Optionee at the address on file with the Company shall be effective to bind Optionee
and any other person who shall acquire rights hereunder. The Company shall be under no obligation whatsoever to advise Optionee of the existence, maturity or termination of any of Optionee’s rights hereunder and Optionee shall be deemed to have
familiarized himself or herself with all matters contained herein and in the Plan which may affect any of Optionee’s rights or privileges hereunder.

 Exhibit 4.5 
 METROCORP BANCSHARES, INC. 
 STOCK APPRECIATION RIGHTS AGREEMENT

 This Stock Appreciation Rights Agreement (the “SAR Agreement”) is made as of the
         day of
                                ,
                 (the “Date of Grant”), between MetroCorp Bancshares, Inc., a Texas corporation (the “Company”), and
                                        
(the “Employee”). 
 To carry out the purposes of the Amended and Restated MetroCorp Bancshares, Inc. 2007 Stock
Awards and Incentive Plan (the “Plan”) by providing employees upon whom the responsibilities of the successful administration and management of the Company rest additional incentive and reward opportunities designed to advance the
profitable growth of the Company, the Company and the Employee hereby agree as follows: 
 1. Grant of Stock Appreciation
Rights. The Company hereby irrevocably grants to Employee
                                        
“Stock Appreciation Rights” under the terms and conditions set forth herein and in the Plan. A “Stock Appreciation Right” is the right to receive a payment from the Company in an amount equal to the “Spread,” which is
defined as the excess of the Fair Market Value (as defined in Plan) of one share of common stock, $1.00 par value (the “Stock”) of the Company at the Exercise Date (as defined below) over a specified price (the “Award Price”)
fixed by the Committee (as defined in the Plan), which shall not be less than 100% of the Fair Market Value of the Stock on the Date of Grant. 
 2. Award Price. The Award Price of the Stock Appreciation Rights hereby granted to Employee is
$                 per Stock Appreciation Right. 
 3. Stock Appreciation Right Period. The Stock Appreciation Rights herein granted may be exercised, in whole or in part, by the Employee during a ten (10) year period beginning on the Date of
Grant (the “SAR Period”), subject to the limitation that the Stock Appreciation Rights shall not be exercisable for more than a percentage of the aggregate number of Stock Appreciation Rights granted by this SAR Agreement determined by the
number of full years of the Employee’s employment with the Company or its Affiliates (as defined in the Plan) from the Date of Grant to the Exercise Date (the “Vested SARs”), in accordance with the following schedule: 

 

			
	 Number of

Full Years
	 	 Percentage

Exercisable

		 	
		 	

 Notwithstanding anything in this SAR Agreement to the contrary, the Committee, in its sole discretion, may waive the
foregoing schedule of vesting and accelerate the earliest date or dates on which any of the Stock Appreciation Rights granted hereunder are exercisable. 
 4. Exercise of Stock Appreciation Rights. Vested SARs shall be exercised by the delivery of written notice to the Secretary of the Company setting forth the number of Vested SARs being exercised
and the date on which such exercise is to be effective (“Exercise Date”). Upon the 

  
 -1-

 
exercise of Vested SARs by the Employee in accordance with this SAR Agreement, the Company shall pay the Employee, within thirty (30) days of the Exercise Date, an amount equal to the
product of (i) the number of Vested SARs exercised, multiplied by (ii) the Spread. Such payment will be made, in the Committee’s discretion, in (a) cash, (b) shares of Stock with a Fair Market Value equal to the amount of
the payment, or (c) a combination of cash and shares of Stock. 
 5. Termination of Employment. If, for any reason
other than death or disability, Employee ceases to be employed by the Company or its Affiliates or ceases to serve as a director or consultant, the Stock Appreciation Rights may be exercised (to the extent Employee would have been entitled to do so
at the date of termination of employment or cessation of serving as a director or consultant) during a three month period after such date (after which period the Stock Appreciation Rights shall expire), but in no event may the Stock Appreciation
Rights be exercised after the expiration of the SAR Period. To the extent the Stock Appreciation Rights are not yet exercisable pursuant to Section 3 hereof on the date of such termination of employment, the Stock Appreciation Rights shall
terminate on the date of termination of employment. Notwithstanding the foregoing, if Employee’s employment is terminated because of Employee’s theft or embezzlement from the Company, disclosure of trade secrets of the Company or the
commission of a willful, felonious act while in the employment of the Company (such reasons shall hereinafter be collectively referred to as “for cause”), then the Stock Appreciation Rights or unexercised portion thereof shall expire upon
such termination of employment. 
 6. Death or Disability. In the event of the death or disability of the Employee while
he is employed by the Company or its Affiliates, all Vested SARs may be exercised at any time and from time to time, within a one-year period after such death or disability by the Employee, his legal representative, the executor or administrator of
his estate or by the person or persons to whom his rights under the SAR Agreement shall pass by will or the laws of descent and distribution, but in no event may any Vested SARs be exercised after their expiration under the terms of this SAR
Agreement. The Employee shall be deemed to be subject to a disability if, in the opinion of a physician selected by the Committee, the Employee is incapable of performing services for the Company of the kind the Employee was performing at the time
the disability occurred by reason of any medically determinable physical or mental impairment which can be expected to result in death or to be of long, continued and indefinite duration. The date of determination of disability for purposes hereof
shall be the date of such determination by such physician. 
 7. Expiration of Units. Any Stock Appreciation Rights
exercised pursuant to this Agreement shall expire automatically as of the Exercise Date. Additionally, Stock Appreciation Rights shall expire upon the Employee’s termination of employment with the Company or its Affiliates in accordance with
Sections 5 and 6 above. 
 8. Extraordinary Corporate Transactions. The existence of outstanding Stock Appreciation
Rights shall not affect in any way the right or power of the Company or its shareholders to make or authorize any or all adjustments, recapitalizations, reorganizations, exchanges or other changes in the Company’s capital structure or its
business, or any merger or consolidation of the Company, or any issuance of Stock or other securities or subscription rights thereto, or any issuance of bonds, debentures, preferred or prior preference stock ahead of or affecting the Stock or the
rights thereof, or the dissolution or liquidation of the Company, or any sale 

  
 -2-

 
or transfer of all or any part of its assets or business, or any other corporate act or proceedings, whether of a similar character or otherwise. Upon the occurrence of a “Change of
Control” (as defined in the Plan), all Stock Appreciation Rights granted hereunder shall be subject to Paragraph XII of the Plan. 
 9. Changes in Capital Structure. Solely for purposes of the Plan and this SAR Agreement, each Stock Appreciation Right has been equated with one share of Stock as constituted on the date of
execution of this SAR Agreement. Upon the occurrence of an event described in Section XII(a) of the Plan, the Stock Appreciation Rights shall be adjusted in accordance with Section XII(a) of the Plan. 

10. Transferability. The Stock Appreciation Rights shall not be transferable by Employee otherwise than by Employee’s will or
by the laws of descent and distribution. During the lifetime of Employee, the Stock Appreciation Rights shall be exercisable only by Employee or his authorized legal representative. Any heir or legatee of Employee shall take rights herein granted
subject to the terms and conditions hereof. No such transfer of the Stock Appreciation Rights to heirs or legatees of Employee shall be effective to bind the Company unless the Company shall have been furnished with written notice thereof and a copy
of such evidence as the Committee may deem necessary to establish the validity of the transfer and the acceptance by the transferee or transferees of the terms and conditions hereof. 

11. Resolution of Disputes. As a condition of the granting of the Stock Appreciation Rights hereby, the Employee and his heirs and
successors agree that any dispute or disagreement which may arise hereunder shall be determined by the Committee in its sole discretion and judgment, and that any such determination and any interpretation by the Committee of the terms of this SAR
Agreement shall be final and shall be binding and conclusive, for all purposes, upon the Company, the Employee, his heirs and personal representatives. 
 12. Employment Relationship. Employee shall be considered to be in the employment of the Company or its Affiliates or in service as a director or consultant so long as he or she remains an
employee, director or consultant of the Company or its Affiliates. Any questions as to whether and when there has been a termination of such employment or service as a director or consultant and the cause of such termination shall be determined by
the Committee, and its determination shall be final. Nothing contained herein shall be construed as conferring upon Employee the right to continue in the employ of the Company or its Affiliates or to continue service as a director or consultant, nor
shall anything contained herein be construed or interpreted to limit the “employment at will” relationship between Employee and the Company or its Affiliates. 
 13. Withholding of Tax. To the extent that this Stock Appreciation Right results in compensation income to the Employee for federal or state income tax purposes, the Employee shall pay to the
Company at the time of such exercise or disposition such amount of money as the Company may require to meet its obligation under applicable tax laws or regulations and, if the Employee fails to do so, the Company is authorized to withhold from any
cash remuneration then or thereafter payable to the Employee, any tax required to be withheld by reason of such resulting compensation income or Company may otherwise refuse to issue or transfer any shares otherwise required to be issued or
transferred pursuant to the terms hereof.
