 Exhibit 10.15 

FORM OF 

INDEMNIFICATION AGREEMENT 

This Indemnification Agreement (“Agreement”) is made as of [ ] by and between Spirit of Texas Bancshares, Inc., a Texas
corporation (the “Company”), and [ ] (“Indemnitee”). This Agreement supersedes and replaces any and all previous agreements between the Company and Indemnitee covering the subject matter of this Agreement (other
than employment agreements that also contain indemnification provisions). 
 RECITALS 

WHEREAS, highly competent persons have become more reluctant to serve publicly-held corporations as directors and officers or in other
capacities unless they are provided with adequate protection through insurance or adequate indemnification against inordinate risks of claims and actions against them arising out of their service to and activities on behalf of the corporation; 

WHEREAS, the Board of Directors of the Company (the “Board”) has determined that, in order to attract and retain qualified
individuals, the Company will attempt to maintain on an ongoing basis, at its sole expense, liability insurance to protect persons serving the Company and its subsidiaries from certain liabilities. Although the furnishing of such insurance has been
a customary and widespread practice among United States-based corporations and other business enterprises, the Company believes that, given current market conditions and trends, such insurance may be available to it in the future only at higher
premiums and with more exclusions. At the same time, directors, officers, and other persons in service to corporations or business enterprises are being increasingly subjected to expensive and time-consuming litigation relating to, among other
things, matters that traditionally would have been brought only against the Company or business enterprise itself. The Organizational Documents (as defined below) require indemnification of the officers and directors of the Company. Indemnitee may
also be entitled to indemnification pursuant the TBOC (as defined below). The Organizational Documents of the Company and the TBOC provide that the indemnification provisions set forth therein are not exclusive, and thereby contemplate that
contracts may be entered into between the Company and members of the board of directors, officers and other persons with respect to indemnification; 

WHEREAS, the uncertainties relating to such insurance and to indemnification have increased the difficulty of attracting and retaining such
persons; 
 WHEREAS, the Board has determined that the increased difficulty in attracting and retaining such persons is detrimental to the
best interests of the Company and its shareholders and that the Company should act to assure such persons that there will be increased certainty of such protection in the future; 

 WHEREAS, it is reasonable, prudent and necessary for the Company contractually to obligate itself
to indemnify, and to advance expenses on behalf of, such persons to the fullest extent permitted by applicable law so that they will serve or continue to serve the Company free from undue concern that they will not be so indemnified; 

WHEREAS, this Agreement is a supplement to and in furtherance of the Organizational Documents and any resolutions adopted pursuant thereto,
and shall not be deemed a substitute therefor, nor to diminish or abrogate any rights of Indemnitee thereunder; 
 WHEREAS, Indemnitee does
not regard the protection available under the Organizational Documents and insurance as adequate in the present circumstances, and may not be willing to serve as an officer or director without adequate protection, and the Company desires Indemnitee
to serve in such capacity. Indemnitee is willing to serve, continue to serve and to take on additional service for or on behalf of the Company on the condition that he be so indemnified; and 

NOW, THEREFORE, in consideration of the premises and the covenants contained herein, the Company and Indemnitee do hereby covenant and agree
as follows: 
 Section 1. Services to the Company. Indemnitee agrees to serve as a director and/or officer of the Company.
Indemnitee may at any time and for any reason resign from such position (subject to any other contractual obligation or any obligation imposed by operation of law), in which event the Company shall have no obligation under this Agreement to continue
Indemnitee in such position. This Agreement shall not be deemed an employment contract between the Company (or any of its subsidiaries or any Enterprise) and Indemnitee. Indemnitee specifically acknowledges that Indemnitee’s employment with the
Company (or any of its subsidiaries or any Enterprise), if any, is at will, and Indemnitee may be discharged at any time for any reason, with or without cause, except as may be otherwise provided in any written employment contract between Indemnitee
and the Company (or any of its subsidiaries or any Enterprise), other applicable formal severance policies duly adopted by the Board, or, with respect to service as a director or officer of the Company, by the Company’s Organizational Documents
and the TBOC. The foregoing notwithstanding, this Agreement shall continue in force after Indemnitee has ceased to serve as an officer and director of the Company, as provided in Section 18 hereof. 

Section 2. Definitions. As used in this Agreement: 

(a) References to “agent” shall mean any person who is or was a director, officer, or employee of the Company or a subsidiary
of the Company or other person authorized by the Company to act for the Company, to include such person serving in such capacity as a director, officer, employee, fiduciary or other member of another corporation, partnership, limited liability
company, joint venture, trust, organization or other enterprise at the request of, for the convenience of, or to represent the interests of the Company or a subsidiary of the Company.

 2 

 
Company’s then outstanding securities unless the change in relative Beneficial Ownership of the Company’s securities by any Person results solely from a reduction in the aggregate
number of outstanding shares of securities entitled to vote generally in the election of directors; 
 ii. Change in Board of Directors.
During any period of two (2) consecutive years (not including any period prior to the execution of this Agreement), individuals who at the beginning of such period constitute the Board, and any new director (other than a director designated by
a person who has entered into an agreement with the Company to effect a transaction described in Sections 2(b)(i), 2(b)(iii) or 2(b)(iv)) whose election by the Board or nomination for election by the Company’s shareholders was approved by a
vote of at least two-thirds of the directors then still in office who either were directors at the beginning of the period or whose election or nomination for election was previously so approved, cease for any
reason to constitute at least a majority of the members of the Board; 
 iii. Corporate Transactions. The effective date of a merger or
consolidation of the Company with any other entity, other than a merger or consolidation which would result in the voting securities of the Company outstanding immediately prior to such merger or consolidation continuing to represent (either by
remaining outstanding or by being converted into voting securities of the surviving entity) more than 51% of the combined voting power of the voting securities of the surviving entity outstanding immediately following such merger or consolidation
and with the power to elect at least a majority of the board of directors or other governing body of such surviving entity; 
 iv.
Liquidation. The approval by the shareholders of the Company of a complete liquidation of the Company or an agreement for the sale or disposition by the Company of all or substantially all of the Company’s assets; and 

v. Other Events. There occurs any other event of a nature that would be required to be reported in response to Item 6(e) of Schedule 14A of

pursuant to his Corporate Status, in each case whether or not serving in such capacity at the time any liability or Expense is incurred for which indemnification, reimbursement, or advancement of Expenses can be provided under this Agreement. If

and beneficiaries of an employee benefit plan shall be deemed to have acted in manner “not opposed to the best interests of the Company” as referred to in this Agreement. 

Section 3. Indemnity in Third-Party Proceedings. The Company shall indemnify Indemnitee in accordance with the provisions of this
Section 3 if Indemnitee is, or is threatened to be made, a party to or a participant in any Proceeding, other than a Proceeding by or in the right of the Company to procure a judgment in its favor. Pursuant to this Section 3, Indemnitee
shall be indemnified to the fullest extent permitted by applicable law against all Expenses, judgments, fines and amounts paid in settlement (including all interest, assessments and other charges paid or payable in connection with or in respect of
such Expenses, judgments, fines and amounts paid in settlement) actually and reasonably incurred by Indemnitee or on his behalf in connection with such Proceeding or any claim, issue or matter therein, if Indemnitee acted in good faith and in a
manner he reasonably believed to be in or not opposed to the best interests of the Company and, 

  
 5 

 
in the case of a criminal Proceeding had no reasonable cause to believe that his conduct was unlawful. The parties hereto intend that this Agreement shall provide to the fullest extent permitted
by law for indemnification in excess of that expressly permitted by statute, including, without limitation, any indemnification provided by the Organizational Documents, vote of its shareholders or disinterested directors or applicable law. 

Section 4. Indemnity in Proceedings by or in the Right of the Company. The Company shall indemnify Indemnitee in accordance with

shall have been finally adjudged by a court to be liable to the Company, unless and only to the extent that a Texas Court or any other court in which the Proceeding was brought shall determine upon application that, despite the adjudication of
liability but in view of all the circumstances of the case, Indemnitee is fairly and reasonably entitled to indemnification. 

Section 5. Indemnification for Expenses of a Party Who is Wholly or Partly Successful. Notwithstanding any other provisions of
this Agreement, to the fullest extent permitted by applicable law and to the extent that Indemnitee is a party to (or a participant in) and is successful, on the merits or otherwise, in any Proceeding or in defense of any claim, issue or matter
therein, in whole or in part, the Company shall indemnify Indemnitee against all Expenses actually and reasonably incurred by him in connection therewith. If Indemnitee is not wholly successful in such Proceeding but is successful, on the merits or
otherwise, as to one or more but less than all claims, issues or matters in such Proceeding, the Company shall indemnify Indemnitee against all Expenses actually and reasonably incurred by him or on his behalf in connection with or related to each
successfully resolved claim, issue or matter to the fullest extent permitted by law. For purposes of this Section and without limitation, the termination of any claim, issue or matter in such a Proceeding by dismissal, with or without prejudice,
shall be deemed to be a successful result as to such claim, issue or matter. 
 Section 6. Indemnification For Expenses of a
Witness. Notwithstanding any other provision of this Agreement, to the fullest extent permitted by applicable law and to the extent that Indemnitee is, by reason of his Corporate Status, a witness or otherwise asked to participate in any
Proceeding to which Indemnitee is not a party, he shall be indemnified against all Expenses actually and reasonably incurred by him or on his behalf in connection therewith. 

Section 7. Partial Indemnification. If Indemnitee is entitled under any provision of this Agreement to indemnification by the
Company for some or a portion of Expenses, but not, however, for the total amount thereof, the Company shall nevertheless indemnify Indemnitee for the portion thereof to which Indemnitee is entitled. 

  
 6 

 Section 8. Additional Indemnification. 

(a) Notwithstanding any limitation in Sections 3, 4, or 5, the Company shall indemnify Indemnitee to the fullest extent permitted by
applicable law if Indemnitee is a party to or threatened to be made a party to any Proceeding (including a Proceeding by or in the right of the Company to procure a judgment in its favor) against all Expenses, judgments, fines and amounts paid in
settlement (including all interest, assessments and other charges paid or payable in connection with or in respect of such Expenses, judgments, fines and amounts paid in settlement) actually and reasonably incurred by Indemnitee in connection with
the Proceeding. 
 (b) For purposes of Section 8(a), the meaning of the phrase “to the fullest extent permitted by applicable
law” shall include, but not be limited to: 
 i. to the fullest extent permitted by the provision of the TBOC that authorizes or
contemplates additional indemnification by agreement, or the corresponding provision of any amendment to or replacement of the TBOC, and 

ii. to the fullest extent authorized or permitted by any amendments to or replacements of the TBOC adopted after the date of this Agreement
that increase the extent to which a corporation may indemnify its officers and directors. 
 Section 9. NOTICE OF ASSUMPTION OF
LIABILITY. THE COMPANY EXPRESSLY ACKNOWLEDGES THAT THE INDEMNITIES CONTAINED IN THIS AGREEMENT REQUIRE ASSUMPTION OF LIABILITY PREDICATED ON THE NEGLIGENCE, GROSS NEGLIGENCE, OR CONDUCT RESULTING IN STRICT LIABILITY OF INDEMNITEE, AND THE
COMPANY ACKNOWLEDGES THAT THIS SECTION 9 COMPLIES WITH ANY REQUIREMENT TO EXPRESSLY STATE LIABILITY FOR NEGLIGENCE, GROSS NEGLIGENCE, OR CONDUCT RESULTING IN STRICT LIABILITY IS CONSPICUOUS AND AFFORDS FAIR AND ADEQUATE NOTICE.  

Section 10. Exclusions. Notwithstanding any provision in this Agreement, the Company shall not be obligated under this Agreement
to make any indemnification payment in connection with any claim made against Indemnitee: 
 (a) for which payment has actually been made to
or on behalf of Indemnitee under any insurance policy or other indemnity provision, except with respect to any excess beyond the amount paid under any insurance policy or other indemnity provision; or 

(b) for (i) an accounting of profits made from the purchase and sale (or sale and purchase) by Indemnitee of securities of the Company
within the meaning of Section 16(b) of the Exchange Act (as defined in Section 2(b) hereof) or similar provisions of state statutory law or common law, or (ii) any reimbursement of the Company by Indemnitee of any bonus or other
incentive-based or equity-based compensation or of any profits realized by Indemnitee from the sale of securities of the Company, as required in each case under the Exchange Act (including any such reimbursements that arise from an accounting
restatement of the Company pursuant to Section 304 of the Sarbanes-Oxley Act or the payment to the Company of profits arising from the purchase and sale by Indemnitee of securities in violation of Section 306 of the Sarbanes-Oxley Act); or

  
 7 

 (c) except as provided in Section 15(d) of this Agreement, in connection with any Proceeding
(or any part of any Proceeding) initiated by Indemnitee, including any Proceeding (or any part of any Proceeding) initiated by Indemnitee against the Company or its directors, officers, employees or other indemnitees, unless (i) the Board
authorized the Proceeding (or any part of any Proceeding) prior to its initiation or (ii) the Company provides the indemnification, in its sole discretion, pursuant to the powers vested in the Company under applicable law. 

Section 11. Advances of Expenses. Notwithstanding any provision of this Agreement to the contrary (other than Section 15(d)),
the Company shall advance, to the extent not prohibited by law, the Expenses incurred by Indemnitee in connection with any Proceeding (or any part of any Proceeding) not initiated by Indemnitee, and such advancement shall be made within thirty
(30) days after the receipt by the Company of a statement or statements requesting such advances from time to time, whether prior to or after final disposition of any Proceeding. Advances shall be unsecured and interest free. Advances shall be
made without regard to Indemnitee’s ability to repay the Expenses and without regard to Indemnitee’s ultimate entitlement to indemnification under the other provisions of this Agreement. In accordance with Section 15(d), advances
shall include any and all reasonable Expenses incurred pursuing an action to enforce this right of advancement, including Expenses incurred preparing and forwarding statements to the Company to support the advances claimed. Indemnitee shall qualify
for advances upon the execution and delivery to the Company of this Agreement, which shall constitute an undertaking providing that Indemnitee undertakes to repay the amounts advanced (without interest) to the extent that it is ultimately determined
that Indemnitee is not entitled to be indemnified by the Company. No other form of undertaking shall be required other than the execution of this Agreement. This Section 11 shall not apply to any claim made by Indemnitee for which indemnity is
excluded pursuant to Section 10. 
 Section 12. Procedure for Notification and Defense of Claim. 

(a) Indemnitee shall notify the Company in writing of any matter with respect to which Indemnitee intends to seek indemnification or
advancement of Expenses hereunder as soon as reasonably practicable following the receipt by Indemnitee of written notice thereof. The written notification to the Company shall include a description of the nature of the Proceeding and the facts
underlying the Proceeding. To obtain indemnification under this Agreement, Indemnitee shall submit to the Company a written request, including therein or therewith such documentation and information as is reasonably available to Indemnitee and is
reasonably necessary to determine whether and to what extent Indemnitee is entitled to indemnification following the final disposition of such Proceeding. The omission by Indemnitee to notify the Company hereunder will not relieve the Company from
any liability which it may have to Indemnitee hereunder or otherwise than under this Agreement, and any delay in so notifying the Company shall not constitute a waiver by Indemnitee of any rights under this Agreement. The Secretary of the Company
shall, promptly upon receipt of such a request for indemnification, advise the Board in writing that Indemnitee has requested indemnification. 

(b) The Company will be entitled to participate in the Proceeding at its own expense.

 Section 13. Procedure Upon Application for Indemnification. 

(a) Upon written request by Indemnitee for indemnification pursuant to Section 12(a), a determination, if required by applicable law,
with respect to Indemnitee’s entitlement thereto shall be made in the specific case: (i) if a Change in Control shall have occurred, by Independent Counsel in a written opinion to the Board, a copy of which shall be delivered to
Indemnitee; or (ii) if a Change in Control shall not have occurred, (A) by a majority vote of the Disinterested Directors, even though less than a quorum of the Board, (B) by a committee of Disinterested Directors designated by a
majority vote of the Disinterested Directors, even though less than a quorum of the Board, (C) if there are no such Disinterested Directors or, if such Disinterested Directors so direct, by Independent Counsel in a written opinion to the Board,
a copy of which shall be delivered to Indemnitee or (D) if so directed by the Board, by the shareholders of the Company; and, if it is so determined that Indemnitee is entitled to indemnification, payment to Indemnitee shall be made within ten
(10) days after such determination. Indemnitee shall cooperate with the person, persons or entity making such determination with respect to Indemnitee’s entitlement to indemnification, including providing to such person, persons or entity
upon reasonable advance request any documentation or information which is not privileged or otherwise protected from disclosure and which is reasonably available to Indemnitee and reasonably necessary to such determination. Any costs or Expenses
(including attorneys’ fees and disbursements) incurred by Indemnitee in so cooperating with the person, persons or entity making such determination shall be borne by the Company (irrespective of the determination as to Indemnitee’s
entitlement to indemnification) and the Company hereby indemnifies and agrees to hold Indemnitee harmless therefrom. The Company promptly will advise Indemnitee in writing with respect to any determination that Indemnitee is or is not entitled to
indemnification, including a description of any reason or basis for which indemnification has been denied. 
 (b) In the event the
determination of entitlement to indemnification is to be made by Independent Counsel pursuant to Section 13(a) hereof, the Independent Counsel shall be selected as provided in this Section 13(b). If a Change in Control shall not have
occurred, the Independent Counsel shall be selected by the Board, and the Company shall give written notice to Indemnitee advising him of the identity of the Independent Counsel so selected. If a Change in Control shall have occurred, the
Independent Counsel shall be selected by Indemnitee (unless Indemnitee shall request that such selection be made by the Board, in which event the preceding sentence shall apply), and Indemnitee shall give written notice to the Company advising it of
the identity of the Independent Counsel so selected. In either event, Indemnitee or the Company, as the case may be, may, within ten (10) days after such written notice of selection shall have been given, deliver to the Company or to
Indemnitee, as the case may be, a written objection to such selection; provided, however, that such objection may be asserted only on the ground that the Independent Counsel so selected does not meet the requirements of
“Independent Counsel” as defined in Section 2 of this Agreement, and the objection shall set forth with particularity the factual basis of such assertion. Absent a proper and timely objection, the person so selected shall act as
Independent Counsel. If such written objection is so made and substantiated, the Independent Counsel so selected may not serve as Independent Counsel unless and until such objection is withdrawn or the Texas Court has determined that such objection
is without merit. If, within twenty (20) days after the later of submission by Indemnitee of a written request for indemnification pursuant to Section 12(a) hereof and the final disposition of the Proceeding, no Independent Counsel shall
have been selected and not objected to, either the Company or Indemnitee may petition the Texas Court for resolution of any objection which shall have been made by the Company or Indemnitee to the other’s selection of Independent Counsel and/or
for the appointment 

  
 9 

 
as Independent Counsel of a person selected by such court or by such other person as such court shall designate, and the person with respect to whom all objections are so resolved or the person
so appointed shall act as Independent Counsel under Section 13(a) hereof. Upon the due commencement of any judicial proceeding or arbitration pursuant to Section 15(a) of this Agreement, Independent Counsel shall be discharged and relieved
of any further responsibility in such capacity (subject to the applicable standards of professional conduct then prevailing). 

Section 14. Presumptions and Effect of Certain Proceedings. 

(a) In making a determination with respect to entitlement to indemnification hereunder, the person or persons or entity making such
determination shall, to the fullest extent not prohibited by law, presume that Indemnitee is entitled to indemnification under this Agreement if Indemnitee has submitted a request for indemnification in accordance with Section 12(a) of this
Agreement, and the Company shall, to the fullest extent not prohibited by law, have the burden of proof to overcome that presumption in connection with the making by any person, persons or entity of any determination contrary to that presumption.
Neither the failure of the Company (including by its directors or Independent Counsel) to have made a determination prior to the commencement of any action pursuant to this Agreement that indemnification is proper in the circumstances because
Indemnitee has met the applicable standard of conduct, nor an actual determination by the Company (including by its directors or Independent Counsel) that Indemnitee has not met such applicable standard of conduct, shall be a defense to the action
or create a presumption that Indemnitee has not met the applicable standard of conduct. 
 (b) Subject to Section 15(e), if the person,
persons or entity empowered or selected under Section 13 of this Agreement to determine whether Indemnitee is entitled to indemnification shall not have made a determination within sixty (60) days after receipt by the Company of the
request therefor, the requisite determination of entitlement to indemnification shall, to the fullest extent not prohibited by law, be deemed to have been made and Indemnitee shall be entitled to such indemnification, absent (i) a misstatement
by Indemnitee of a material fact, or an omission of a material fact necessary to make Indemnitee’s statement not materially misleading, in connection with the request for indemnification, or (ii) a prohibition of such indemnification under
applicable law; provided, however, that such 60-day period may be extended for a reasonable time, not to exceed an additional thirty (30) days, if the person, persons or entity making the determination
with respect to entitlement to indemnification in good faith requires such additional time for the obtaining or evaluating of documentation and/or information relating thereto; and provided, further, that the foregoing provisions of this
Section 14(b) shall not apply if the determination of entitlement to indemnification is to be made by the shareholders pursuant to Section 13(a) of this Agreement and if (A) within fifteen (15) days after receipt by the Company
of the request for such determination the Board has resolved to submit such determination to the shareholders for their consideration at an annual meeting thereof to be held within seventy-five (75) days after such receipt and such
determination is made thereat, or (B) a special meeting of shareholders is called within fifteen (15) days after such receipt for the purpose of making such determination, such meeting is held for such purpose within sixty (60) days
after having been so called and such determination is made thereat. 

  
 10 

 (c) The termination of any Proceeding or of any claim, issue or matter therein, by judgment,
order, settlement or conviction, or upon a plea of nolo contendere or its equivalent, shall not (except as otherwise expressly provided in this Agreement) of itself adversely affect the right of Indemnitee to indemnification or create a
presumption that Indemnitee did not act in good faith and in a manner which he reasonably believed to be in or not opposed to the best interests of the Company or, with respect to any criminal Proceeding, that Indemnitee had reasonable cause to
believe that his conduct was unlawful. 
 (d) For purposes of any determination of good faith, Indemnitee shall be deemed to have acted in
good faith if Indemnitee’s action is based on the records or books of account of the Enterprise, including financial statements, or on information supplied to Indemnitee by the directors or officers of the Enterprise in the course of their
duties, or on the advice of legal counsel for the Enterprise or on information or records given or reports made to the Enterprise by an independent certified public accountant or by an appraiser or other expert selected with the reasonable care by
the Enterprise. The provisions of this Section 14(d) shall not be deemed to be exclusive or to limit in any way the other circumstances in which Indemnitee may be deemed to have met the applicable standard of conduct set forth in this
Agreement. 
 (e) The knowledge and/or actions, or failure to act, of any director, officer, trustee, partner, managing member, fiduciary,
agent or employee of the Enterprise shall not be imputed to Indemnitee for purposes of determining the right to indemnification under this Agreement. 

Section 15. Remedies of Indemnitee. 

(a) Subject to Section 15(e), in the event that (i) a determination is made pursuant to Section 13 of this Agreement that
Indemnitee is not entitled to indemnification under this Agreement, (ii) advancement of Expenses is not timely made pursuant to Section 11 of this Agreement, (iii) no determination of entitlement to indemnification shall have been
made pursuant to Section 13(a) of this Agreement within ninety (90) days after receipt by the Company of the request for indemnification, (iv) payment of indemnification is not made pursuant to Section 5, 6 or 7 or the last
sentence of Section 13(a) of this Agreement within ten (10) days after receipt by the Company of a written request therefor, (v) payment of indemnification pursuant to Section 3, 4 or 8 of this Agreement is not made within ten
(10) days after a determination has been made that Indemnitee is entitled to indemnification, or (vi) the Company or any other person takes or threatens to take any action to declare this Agreement void or unenforceable, or institutes any
litigation or other action or Proceeding designed to deny, or to recover from, Indemnitee the benefits provided or intended to be provided to Indemnitee hereunder, Indemnitee shall be entitled to an adjudication by a court of his entitlement to such
indemnification or advancement of Expenses. Alternatively, Indemnitee, at his option, may seek an award in arbitration to be conducted by a single arbitrator pursuant to the Commercial Arbitration Rules of the American Arbitration Association.
Indemnitee shall commence such proceeding seeking an adjudication or an award in arbitration within 180 days following the date on which Indemnitee first has the right to commence such proceeding pursuant to this Section 15(a); provided,
however, that the foregoing clause shall not apply in respect of a proceeding brought by Indemnitee to enforce his rights under Section 5 of this Agreement. The Company shall not oppose Indemnitee’s right to seek any such
adjudication or award in arbitration. 

  
 11 

 (b) In the event that a determination shall have been made pursuant to Section 13(a) of this
Agreement that Indemnitee is not entitled to indemnification, any judicial proceeding or arbitration commenced pursuant to this Section 15 shall be conducted in all respects as a de novo trial, or arbitration, on the merits and
Indemnitee shall not be prejudiced by reason of that adverse determination. In any judicial proceeding or arbitration commenced pursuant to this Section 15 the Company shall have the burden of proving Indemnitee is not entitled to
indemnification or advancement of Expenses, as the case may be. 
 (c) If a determination shall have been made pursuant to
Section 13(a) of this Agreement that Indemnitee is entitled to indemnification, the Company shall be bound by such determination in any judicial proceeding or arbitration commenced pursuant to this Section 15, absent (i) a
misstatement by Indemnitee of a material fact, or an omission of a material fact necessary to make Indemnitee’s statement not materially misleading, in connection with the request for indemnification, or (ii) a prohibition of such
indemnification under applicable law. 
 (d) The Company shall, to the fullest extent not prohibited by law, be precluded from asserting in
any judicial proceeding or arbitration commenced pursuant to this Section 15 that the procedures and presumptions of this Agreement are not valid, binding and enforceable and shall stipulate in any such court or before any such arbitrator that
the Company is bound by all the provisions of this Agreement. It is the intent of the Company that, to the fullest extent permitted by law, Indemnitee not be required to incur legal fees or other Expenses associated with the interpretation,
enforcement or defense of Indemnitee’s rights under this Agreement by litigation or otherwise because the cost and expense thereof would substantially detract from the benefits intended to be extended to Indemnitee hereunder. The Company shall,
to the fullest extent permitted by law, indemnify Indemnitee against any and all Expenses and, if requested by Indemnitee, shall (within ten (10) days after receipt by the Company of a written request therefor) advance, to the extent not
prohibited by law, such Expenses to Indemnitee, which are incurred by Indemnitee in connection with any action brought by Indemnitee for indemnification or advance of Expenses from the Company under this Agreement or under any directors’ and
officers’ liability insurance policies maintained by the Company if, in the case of indemnification, Indemnitee is wholly successful on the underlying claims; if Indemnitee is not wholly successful on the underlying claims, then such
indemnification shall be only to the extent Indemnitee is successful on such underlying claims or otherwise as permitted by law, whichever is greater. 

(e) Notwithstanding anything in this Agreement to the contrary, no determination as to entitlement of Indemnitee to indemnification under this
Agreement shall be required to be made prior to the final disposition of the Proceeding. 
 Section 16. Non-exclusivity; Survival of Rights; Insurance; Subrogation. 
 (a) The rights of indemnification and
to receive advancement of Expenses as provided by this Agreement shall not be deemed exclusive of any other rights to which Indemnitee may at any time be entitled under applicable law, the Organizational Documents, any agreement, a vote of
shareholders or a resolution of directors, or otherwise. No amendment, alteration or repeal of this Agreement or of any provision hereof shall limit or restrict any right of Indemnitee under this Agreement in respect of any action taken or omitted
by such Indemnitee in his Corporate Status prior to such amendment, alteration or repeal. To the extent that a change in Texas law, 

  
 12 

 
whether by statute or judicial decision, permits greater indemnification or advancement of Expenses than would be afforded currently under the Organizational Documents and this Agreement, it is
the intent of the parties hereto that Indemnitee shall enjoy by this Agreement the greater benefits so afforded by such change. No right or remedy herein conferred is intended to be exclusive of any other right or remedy, and every other right and
remedy shall be cumulative and in addition to every other right and remedy given hereunder or now or hereafter existing at law or in equity or otherwise. The assertion or employment of any right or remedy hereunder, or otherwise, shall not prevent
the concurrent assertion or employment of any other right or remedy. 
 (b) To the extent that the Company maintains an insurance policy or
policies providing liability insurance for directors, officers, employees, or agents of the Enterprise, Indemnitee shall be covered by such policy or policies in accordance with its or their terms to the maximum extent of the coverage available for
any such director, officer, employee or agent under such policy or policies. If, at the time of the receipt of a notice of a claim pursuant to the terms hereof, the Company has director and officer liability insurance in effect, the Company shall
give prompt notice of such claim or of the commencement of a Proceeding, as the case may be, to the insurers in accordance with the procedures set forth in the respective policies. The Company shall thereafter take all necessary or desirable action
to cause such insurers to pay, on behalf of Indemnitee, all amounts payable as a result of such Proceeding in accordance with the terms of such policies. 

(c) In the event of any payment under this Agreement, the Company shall be subrogated to the extent of such payment to all of the rights of
recovery of Indemnitee, who shall execute all papers required and take all action necessary to secure such rights, including execution of such documents as are necessary to enable the Company to bring suit to enforce such rights. 

(d) The Company shall not be liable under this Agreement to make any payment of amounts otherwise indemnifiable (or for which advancement is
provided hereunder) hereunder if and to the extent that Indemnitee has otherwise actually received such payment under any insurance policy, contract, agreement or otherwise. 

(e) The Company’s obligation to indemnify or advance Expenses hereunder to Indemnitee who is or was serving at the request of the Company
as a director, officer, trustee, partner, managing member, fiduciary, employee or agent of any other corporation, limited liability company, partnership, joint venture, trust, employee benefit plan, organization or other enterprise shall be reduced
by any amount Indemnitee has actually received as indemnification or advancement of Expenses from such other corporation, limited liability company, partnership, joint venture, trust, organization or other enterprise. 

Section 17. Duration of Agreement. This Agreement shall continue until and terminate upon the later of: (a) ten (10) years
after the date that Indemnitee shall have ceased to serve as a director and officer of the Company or (b) one (1) year after the final termination of any Proceeding then pending in respect of which Indemnitee is granted rights of
indemnification or advancement of Expenses hereunder and of any proceeding commenced by Indemnitee pursuant to Section 15 of this Agreement relating thereto. The indemnification and advancement of expenses rights provided by or granted pursuant
to this Agreement shall be binding upon and be enforceable by the parties hereto and their respective successors and assigns (including any direct or indirect 

  
 13 

 
successor by purchase, merger, consolidation or otherwise to all or substantially all of the business or assets of the Company), shall continue as to an Indemnitee who has ceased to be a
director, officer, employee or agent of the Company or of any other Enterprise, and shall inure to the benefit of Indemnitee and his or her spouse, assigns, heirs, devisees, executors and administrators and other legal representatives. 

Section 18. Severability. If any provision or provisions of this Agreement shall be held to be invalid, illegal or unenforceable
for any reason whatsoever: (a) the validity, legality and enforceability of the remaining provisions of this Agreement (including without limitation, each portion of any Section of this Agreement containing any such provision held to be
invalid, illegal or unenforceable, that is not itself invalid, illegal or unenforceable) shall not in any way be affected or impaired thereby and shall remain enforceable to the fullest extent permitted by law; (b) such provision or provisions
shall be deemed reformed to the extent necessary to conform to applicable law and to give the maximum effect to the intent of the parties hereto; and (c) to the fullest extent possible, the provisions of this Agreement (including, without
limitation, each portion of any Section of this Agreement containing any such provision held to be invalid, illegal or unenforceable, that is not itself invalid, illegal or unenforceable) shall be construed so as to give effect to the intent
manifested thereby. 
 Section 19. Enforcement. 

(a) The Company expressly confirms and agrees that it has entered into this Agreement and assumed the obligations imposed on it hereby in
order to induce Indemnitee to serve as a director or officer of the Company, and the Company acknowledges that Indemnitee is relying upon this Agreement in serving as a director or officer of the Company. 

(b) This Agreement constitutes the entire agreement between the parties hereto with respect to the subject matter hereof and supersedes all
prior agreements and understandings, oral, written and implied, between the parties hereto with respect to the subject matter hereof; provided, however, that this Agreement is a supplement to and in furtherance of the Organizational Documents and
applicable law, and shall not be deemed a substitute therefor, nor to diminish or abrogate any rights of Indemnitee thereunder. 

Section 20. Modification and Waiver. No supplement, modification or amendment of this Agreement shall be binding unless executed
in writing by the parties hereto. No waiver of any of the provisions of this Agreement shall be deemed or shall constitute a waiver of any other provisions of this Agreement nor shall any waiver constitute a continuing waiver. 

Section 21. Notice by Indemnitee. Indemnitee agrees promptly to notify the Company in writing upon being served with any summons,
citation, subpoena, complaint, indictment, information or other document relating to any Proceeding or matter which may be subject to indemnification or advancement of Expenses covered hereunder. The failure of Indemnitee to so notify the Company
shall not relieve the Company of any obligation which it may have to Indemnitee under this Agreement or otherwise. 

  
 14 

 Section 22. Notices. All notices, requests, demands and other communications under
this Agreement shall be in writing and shall be deemed to have been duly given if (a) delivered by hand and receipted for by the party to whom said notice or other communication shall have been directed, (b) mailed by certified or
registered mail with postage prepaid, on the third business day after the date on which it is so mailed, (c) mailed by reputable overnight courier and receipted for by the party to whom said notice or other communication shall have been

Section 23. Contribution. To the fullest extent permissible under applicable law, if the indemnification provided for in this
Agreement is unavailable to Indemnitee for any reason whatsoever, the Company, in lieu of indemnifying Indemnitee, shall contribute to the amount incurred by Indemnitee, whether for judgments, fines, penalties, excise taxes, amounts paid or to be
paid in settlement and/or for Expenses, in connection with any claim relating to an indemnifiable event under this Agreement, in such proportion as is deemed fair and reasonable in light of all of the circumstances of such Proceeding in order to
reflect (i) the relative benefits received by the Company and Indemnitee as a result of the event(s) and/or transaction(s) giving cause to such Proceeding; and/or (ii) the relative fault of the Company (and its directors, officers,
employees and agents) and Indemnitee in connection with such event(s) and/or transaction(s). 
 Section 24. Applicable Law and
Consent to Jurisdiction. This Agreement and the legal relations among the parties shall be governed by, and construed and enforced in accordance with, the laws of the State of Texas, without regard to its conflict of laws rules. Except with

this Agreement shall be brought only in the Texas Court and not in any other state or federal court in the United States of America or any court in any other country, (ii) consent to submit to the exclusive jurisdiction of the Texas Court for
purposes of any action or proceeding arising out of or in connection with this Agreement, (iii) waive any objection to the laying of venue of any such action or proceeding in the Texas Court, and (iv) waive, and agree not to plead or to
make, any claim that any such action or proceeding brought in the Texas Court has been brought in an improper or inconvenient forum.

 NONQUALIFIED 

SUPPLEMENTAL DEFERRED COMPENSATION PLAN 

- PLAN DOCUMENT - 

SECTION 1 INTRODUCTION 
  

	 	1.1	Adoption of Plan and Purpose 

 This Plan is an unfunded, nonqualified deferred
compensation plan. With the consent of the Employer (as defined in subsection 2.16) the plan may be adopted by executing the Adoption Agreement (as defined in subsection 2.3) in the form attached hereto. The Plan contains certain variable features
which the Employer has specified in the Adoption Agreement. Only those variable features specified by the Employer in the Adoption Agreement will be applicable to the Employer. 

The purpose of the Plan is to provide certain supplemental benefits under the Plan to a select group of management or highly compensated
Employees of the Employer (in accordance with Sections 201, 301 and 401 of ERISA), Members of the Board(s) of the Employer, or Other Service Providers to the Employer (as defined below), and to allow such Employees, Board Members or Other Service
Providers the opportunity to defer a portion of their salaries, bonuses and other compensation, subject to the terms of the Plan. Participants (and their Beneficiaries) shall have only those rights to payments as set forth in the Plan and shall be
considered general, unsecured creditors of the Employer with respect to any such rights. The Plan is designed to comply with Code Section 409A and all guidance issued in connection with Code Section 409A. It is intended that the Plan be
interpreted according to a good faith interpretation of Code Section 409A, and consistent with published IRS guidance, including proposed and final IRS regulations under Code Section 409A. Treatment of amounts in the Plan under any
transition rules provided under all IRS and other guidance in connection with Code Section 409A shall be expressly authorized hereunder in accordance with procedures developed by the Administrator. In the event of any inconsistency between the
terms of the Plan and Code Section 409A (and regulations thereunder), the terms of Code Section 409A (and the regulations thereunder) shall control. The Plan is intended to constitute an account balance plan (as defined in Treasury
Regulation Section 1.409A-1(c)). 
 By becoming a Participant and making deferrals under this
Plan, each Participant agrees to be bound by the provisions of the Plan and the determinations of the Employer and the Administrator hereunder.

	 	1.4	Plan Administration 

 The plan shall be administered by a plan administrator (the
“Administrator,” as that term is defined in Section 3(16)(A) of ERISA) designated by the Employer in the Adoption Agreement. The Administrator has full discretionary authority to construe and interpret the provisions of the Plan and
make factual determinations thereunder, including the power to determine the rights or eligibility of employees or participants and any other persons, and the amounts of their benefits under the plan, and to remedy ambiguities, inconsistencies or
omissions, and such determinations shall be binding on all parties. The Administrator from time to time may adopt such rules and regulations as may be necessary or desirable for the proper and efficient administration of the Plan and as are
consistent with the terms of the Plan. The administrator may delegate all or any part of its powers, rights, and duties under the Plan to such person or persons as it may deem advisable, and may engage agents to provide certain administrative
services with respect to the Plan. Any notice or document relating to the Plan which is to be filed with the Administrator may be delivered, or mailed by registered or certified mail, postage pre-paid, to the
Administrator, or to any designated representative of the Administrator, in care of the Employer, at its principal office.

Agreement, and its successors and assigns unless otherwise herein provided, or any other corporation or business organization which, with the consent of the Employer, or its successors or assigns, assumes the Employer’s obligations hereunder,

Adoption Agreement, by receiving a Matching Contribution or other Employer Contribution under the Plan. Each Eligible Individual’s decision to become a Participant by making a Deferral Election shall be entirely voluntary. The Employer may
require the Participant to complete any necessary forms or other information as it deems necessary or advisable prior to permitting the Eligible Individual to commence participation in the Plan. 

 

	 	3.2	Cessation of Participation 

 If a Termination Date occurs with respect to a Participant,
or if a Participant otherwise ceases to be an Eligible Individual, no further Compensation Deferrals, Performance-Based Bonus Deferrals, Matching Contributions or other Employer Contributions shall be credited to the Participant’s Accounts
after the Participant’s Termination Date or date the Participant ceases to be eligible (or as soon as administratively feasible after the date the Participant ceases to be eligible or, if applicable, the end of the then-current Plan Year or
performance period with respect to Performance-Based Bonuses), unless he is again determined to be an Eligible Individual, but the balance credited to his Accounts shall continue to be adjusted for notional investment gains and losses under the
terms of the Plan and shall be distributed to him at the time and manner set forth in Section 9. An Employee, Board Member or Other Service Provider shall cease to be a Participant after his Termination Date or other loss of eligibility as soon
as his entire Account balance has been distributed. 
  

	 	3.3	Eligibility for Matching or Employer Contributions 

 An Employee Participant who has
satisfied the requirements necessary to become an Eligible Individual with respect to Matching Contributions as specified in the Adoption Agreement, and who has made a Compensation Deferral election pursuant to subsection 4.1 herein or who has
satisfied such other criteria as specified in the Adoption Agreement, shall be eligible to receive Matching Contributions described in subsection 4.3. An Employee Participant who has satisfied the requirements necessary to become an Eligible
Individual with respect to Employer Contributions other than Matching Contributions as specified in the Adoption Agreement, shall be eligible to receive Employer Contributions described in subsection 4.4.

 SECTION 4 DEFERRALS AND CONTRIBUTIONS 

 

	 	4.1	Compensation Deferrals Other Than Performance-Based Bonus Deferrals 

 Each Plan Year, an Eligible
Individual may elect to defer receipt of no less than the minimum and no greater than the maximum percentage or amount selected by the Employer in the Adoption Agreement with respect to each type of Compensation (other than Performance-Based
Bonuses) earned with respect to pay periods beginning on and after the effective date of the election; provided, however, that Compensation earned prior to the date the Participant satisfies the eligibility requirements of Section 3 shall not
be eligible for deferral under this Plan. Except as otherwise provided in this subsection, a Participant’s Deferral Election for a Plan Year under this subsection must be made not later than December 31 of the preceding Plan Year (or such
earlier date as determined by the Administrator) with respect to Compensation (other than Performance-Based Bonuses) earned in pay periods beginning on or after the following January 1 in accordance with rules established by the Administrator.
An election to defer restricted stock units (RSUs) into the Plan must be made by one of the following deadlines: (i) the end of the calendar year prior to the date of grant of the RSU; (ii) 12 months before the payment date of the RSU (vesting
date is treated as the payment date for these purposes), but the election will not take effect for 12 months, and the subsequent payout date must be at least five years later than the original payment date); (iii) within 30 days of the date of grant
(but only if the RSU is structured so that vesting is contingent on the Participant performing services for at least an additional 12 months); or (iv) within 6 months of the payment (vesting) date, but only if the RSU is performance-based under
Code Section 409A, and only if the performance period must be at least 12 months long and either: (a) the amount of the compensation cannot be reasonably ascertained at the time of the election, or (b) the performance requirement is
still not substantially certain to be met at the time of the election. If the Employer allows for deferral of RSUs structured so that a specified portion of the RSU grant vests periodically (for example, an RSU grant over a four-year period vesting
25% annually), then the election to defer may be made separately with respect to each portion of the grant that vests in a given year, if permitted by the Employer. However, each election for each portion of the grant must be made either:
(i) within thirty days of the date of grant or each anniversary thereof, and only if the RSU is structured so that vesting is contingent on the employee performing services for at least an additional 12 months subsequent to the election; or
(ii) 12 months before the payment date of the RSU (vesting date is treated as the payment date for these purposes), but the election will not take effect for 12 months, and the subsequent payout date must be at least five years later than the
previous payment date. 
 An Employee, Board Member or Other Service Provider who first becomes an Eligible Individual during a Plan Year
(by virtue of a promotion, Compensation increase, commencement of employment with the Employer, commencement of Board service, execution of an agreement to provide services to an Employer, or any other reason) shall be provided enrollment documents
(including Deferral Election forms) as soon as administratively feasible following such initial notification of eligibility. Such Eligible Individual must make his Deferral Elections within 30 days after first becoming an Eligible Individual,
with respect to his Compensation (other than Performance-Based Bonuses) earned on or after the effective date of the Deferral Election 

  
 - 10 - 

 
(provided, however, that if such Eligible Individual is participating in any other account balance plan maintained by the Employer or any member of the Employer’s “controlled
group” (as defined in subsections 414(b) and (c) of the Code), such Eligible Individual must make his Compensation Deferral Election no later than December 31 of the preceding Plan Year (or such earlier date as determined by the
Administrator), or he may not elect to make Compensation Deferrals for that initial Plan Year). If an Eligible Individual does not elect to make Compensation Deferrals during that initial 30-day period, he may
not later elect to make Compensation Deferrals for that year under this subsection. In the event that an Eligible Individual first becomes eligible during a Plan Year with respect to which Fiscal Year Compensation is payable, such Eligible
Individual must make his Fiscal Year Compensation Deferral Election on or before the end of the fiscal year of the Employer immediately preceding the first fiscal year in which any services are performed for which the Fiscal Year Compensation is
payable. 
 In the case of an Employee, Board Member or Other Service Provider who is rehired (or who recommences Board Service or
recommences providing services to an Employer as an Other Service Provider) after having previously been an Eligible Individual, the phrase “first becomes an Eligible Individual” in the first sentence of the preceding paragraph shall be
interpreted to apply only where the Eligible Individual either (i) previously received payment of his total Account balances under the Plan, or (ii) did not previously receive payment of his total Account balances under the Plan, but is
rehired (or recommences Board Service or recommences providing services to an Employer as an Other Service Provider) at least 24 months after his last day as a previously Eligible Individual prior to again becoming such an Eligible Individual. In
all other cases such rehired Employee, Board Member or Other Service Provider may not elect to make Compensation Deferrals until the next date determined by the Administrator with respect to Compensation earned after the following January 1.
Similarly, in the case of an Employee who recommences status as an Eligible Individual for any other reason after having previously lost his status as an Eligible Individual (due to Compensation fluctuations, transfer from an ineligible location or
job classification, or otherwise), the phrase “first becomes an Eligible Individual” shall be interpreted to apply only where the Eligible Individual either: (i) previously received payment of his total Account balances under the
Plan, or (ii) did not previously receive payment of his total Account balances under the Plan, but regains his status as an Eligible Individual at least 24 months after his last day as a previously Eligible Individual prior to again becoming
such an Eligible Individual. In all other cases such Re-Eligible Participant may not elect to make Compensation Deferrals until the next date determined by the Administrator with respect to Compensation earned
after the following January 1. 
 An election to make Compensation Deferrals under this subsection 4.1 shall remain in effect through the
last pay period commencing in the calendar year to which the election applies (except as provided in subsections 2.9 or 4.5), shall apply with respect to the applicable type of Compensation (other than Performance-Based Bonuses) to which the
Deferral Election relates earned for pay periods commencing in the applicable calendar year to which the election applies, and shall be irrevocable (provided, however, that a Participant making a Deferral Election under this subsection may change
his election at any time prior to December 31 of the year preceding the year for which the Deferral Election is applicable, subject to rules established by the 

  
 - 11 - 

 
Administrator). If a Participant fails to make a Compensation Deferral election for a given Plan Year, such Participant’s Compensation Deferral Election for that Plan Year shall be deemed to
be zero; provided, however, that if the Employer has elected in the Adoption Agreement that a Participant’s Compensation Deferral Election shall be “evergreen”, then such Participant’s Compensation Deferral Election shall be
deemed to be identical to the most recent applicable Deferral Election on file with the Administrator with respect to the applicable type of Compensation; provided, however, that no In-Service Distribution
shall be applicable to any amounts deferred in a year in which the Participant fails to make an affirmative election, and payment of such amounts for such year shall be made in accordance with his most recent election on file with the Administrator
(if no election is on file, then such amounts shall be paid to him in a single lump sum). 
 Compensation Deferrals shall be credited to the
Participant’s Compensation Deferral Account as soon as administratively feasible after such amounts would have been payable to the Participant. 
  

	 	4.2	Performance-Based Bonus Deferrals 

 Each Plan Year, an Eligible Individual may elect to
defer receipt of no less than the minimum and no greater than the maximum percentage or amount selected by the Employer in the Adoption Agreement with respect to Performance-Based Bonuses earned with respect to the performance period for which the
Performance-Based Bonus is earned; provided, however, that the Eligible Individual performed services continuously from a date no later than the date upon which the performance criteria are established through a date no earlier than the date upon
which the Eligible Individual makes a Performance-Based Bonus Deferral Election; and further provided that in no event may an election to defer Performance-Based Bonuses be made after such Bonuses have become readily ascertainable. Except as
otherwise provided in this subsection, a Participant’s Performance-Based Bonus Deferral Election under this subsection must be made not later than six months (or such earlier date as determined by the Administrator) prior to the end of the
performance period. 
 An Employee, Board Member or Other Service Provider who first becomes an Eligible Individual during a Plan Year (by
virtue of a promotion, Compensation increase, commencement of employment with the Employer, commencement of Board service, execution of an agreement to provide services to an Employer, or any other reason) shall be provided enrollment documents
(including Deferral Election forms) as soon as administratively feasible following such initial notification of eligibility. Such Eligible Individual must make his Performance-Based Bonus Deferral Election within 30 days after first becoming
an Eligible Individual (provided, however, that if such Eligible Individual is participating in any other account balance plan maintained by the Employer or any member of the Employer’s “controlled group” (as defined in subsections
414(b) and (c) of the Code), such Eligible Individual must perform services continuously from a date no later than the date the performance criteria are established, and must make his Performance-Based Bonus Deferral Election no later than six
months (or such earlier date as determined by the Administrator) prior to the end of the performance period, and at a time when the Performance-Based Bonus is not readily ascertainable, or he may not elect to make

  
 - 12 - 

 
Performance-Based Bonus Deferrals for such initial Plan Year. In the case of a Deferral Election in the first year of eligibility that is made after the beginning of the Performance-Based Bonus
performance period, the Deferral Election will apply to the portion of the Performance-Based Bonus equal to the total amount of the Performance-Based Bonus for the performance period multiplied by the ratio of the number of days remaining in the
performance period after the effective date of the Deferral Election over the total number of days in the Performance Period. If an Eligible Individual does not elect to make a Performance-Based Bonus Deferral during that initial 30-day period, he may not later elect to make a Performance-Based Bonus Deferral for that performance period under this subsection. Rules relating to the timing of elections to make a Performance-Based Bonus
Deferral with respect to an Employee, Board Member or Other Service Provider who becomes an Eligible Individual (due to rehire or other similar event) after having previously been an Eligible Individual shall be applied in a manner similar to rules
described applicable to rehired and other Re-Eligible Participants in subsection 4.1 above. 
 An
election to make Performance-Based Bonus Deferrals under this subsection 4.2 shall remain in effect through the end of the performance period to which the election applies (except as provided in subsection 4.5), and shall be irrevocable (provided,
however, that a Participant making a Performance-Based Bonus Deferral Election under this subsection with respect to a Performance-Based Bonus that is not yet readily ascertainable, may change his election at any time prior to the first day of the six-month period ending on the last day of the performance period for which the Performance-Based Bonus Deferral Election is applicable, subject to rules established by the Administrator). If a Participant fails to
make a Performance-Based Bonus Deferral Election for a given performance period, such Participant’s Performance-Based Bonus Deferral Election for that performance period shall be deemed to be zero; provided, however, that if the Employer has
elected in the Adoption Agreement that a Participant’s Performance-Based Deferral Election shall be “evergreen”, then such Participant’s Performance-Based Bonus Deferral Election shall be deemed to be identical to the most recent
applicable Performance-Based Bonus Deferral Election on file with the Administrator; provided, however, that no In-Service Distribution shall be applicable to any amounts deferred in a year in which the
Participant fails to make an affirmative election, and payment of such amounts for such year shall be made in accordance with his most recent election on file with the Administrator (if no election is on file, then such amounts shall be paid to him
in a single lump sum). 
 Performance-Based Bonus Deferrals shall be credited to the Participant’s Compensation Deferral Account as
soon as administratively feasible after such amounts would have been payable to the Participant. 
  

	 	4.3	Matching Contributions 

 Matching Contributions shall be determined in accordance with
the formula specified in the Adoption Agreement, and shall be credited to the Employer Contribution Accounts of Participants who have satisfied the eligibility requirements for Matching Contributions specified in the Adoption Agreement. Matching
Contributions under this Plan shall be credited to such Participants’ Employer Contribution Accounts as soon as administratively feasible after the Applicable Period selected in the Adoption Agreement, but only with respect to Participants
eligible to receive such Matching Contributions as described in the Adoption Agreement. 

  
 - 13 - 

	 	4.4	Other Employer Contributions 

 Employer Contributions other than Matching Contributions
shall be discretionary from year to year, and shall be credited to the Employer Contribution Accounts of Participants who have satisfied the eligibility requirements for Employer Contributions, all as determined by the Employer and documented in
writing, and such writings will form part of the Plan, as specified in the Adoption Agreement. Employer Contributions under this Plan shall be credited to such Participants’ Employer Contributions Accounts as soon as administratively feasible.

  

	 	4.5	No Election Changes During Plan Year 

 A Participant shall not be permitted to change or
revoke his Deferral Elections (except as otherwise described in subsections 4.1 and 4.2), except that, if a Participant’s status changes such that he becomes ineligible for the Plan, the Participant’s Deferrals under the Plan shall cease
as described in subsection 3.2. Notwithstanding the foregoing, in the event the Employer maintains a qualified plan designed to comply with the requirements of Code Section 401(k) that requires the cessation of all deferrals in the event
of a hardship withdrawal under such plan, the Participant’s Deferrals under this Plan shall cease as soon as administratively feasible upon notification to the Administrator that the participant has taken such a hardship withdrawal.
Notwithstanding the foregoing, if the Employer has elected in the Adoption Agreement to permit Unforeseeable Emergency Withdrawals pursuant to subsection 9.8, the Participant’s Deferrals under this Plan shall cease as soon as administratively
feasible upon approval by the Administrator of a Participant’s properly submitted request for an Unforeseeable Emergency Withdrawal under subsection 9.8. 
  

	 	4.6	Crediting of Deferrals 

 The amount of deferrals pursuant to subsections 4.1 and 4.2
shall be credited to the Participant’s Accounts as of a date determined to be administratively feasible by the Administrator. 
  

	 	4.7	Reduction of Deferrals or Contributions 

 Any Participant Deferrals or Employer
Contributions to be credited to a Participant’s Account under this Section may be reduced by an amount equal to the Federal or state, local or foreign income, payroll, or other taxes required to be withheld on such deferrals or contributions or
to satisfy any necessary contributions under an employee welfare benefit plan described under Section 125 of the Code. A Participant shall be entitled only to the net amount of such deferral or contribution (as adjusted from time to time
pursuant to the terms of the Plan). The Administrator may notify a Participant of limitations on his Deferral Election if, as a result of any election, a Participant’s Compensation from the Employer would be insufficient to cover taxes,
withholding, and other required deductions applicable to the Participant. 

  
 - 14 - 

 SECTION 5 NOTIONAL INVESTMENTS 

 

	 	5.1	Investment Funds 

 The Employer may designate, in its discretion, one or more Investment
Funds for the notional investment of Participants’ Accounts. The Employer, in its discretion, may from time to time establish new Investment Funds or eliminate existing Investment Funds. The Investment Funds are for recordkeeping purposes only
and do not allow Participants to direct any Employer assets (including, if applicable, the assets of any trust related to the Plan). Each Participant’s Accounts shall be adjusted pursuant to the Participant’s notional investment elections
made in accordance with this Section 5, except as otherwise determined by the Employer or Administrator in their sole discretion. 
  

	 	5.2	Investment Fund Elections 

 The Employer shall have full discretion in the direction of
notional investments of Participants’ Accounts under the Plan; provided, however, that if the Employer so elects in the Adoption Agreement, each Participant may elect from among the Investment Funds for the notional investment of such of his
Accounts as are permitted under the Adoption Agreement from time to time in accordance with procedures established by the Employer. The Administrator, in its discretion, may adopt (and may modify from time to time) such rules and procedures as it
deems necessary or appropriate to implement the notional investment of the Participant’s Accounts. Such procedures may differ among Participants or classes of Participants, as determined by the Employer or the Administrator in its discretion.
The Employer or Administrator may limit, delay or restrict the notional investment of certain Participants’ Accounts, or restrict allocation or reallocation into specified notional investment options, in accordance with rules established in
order to comply with Employer policy and applicable law, to minimize regulated filings and disclosures, or under any other circumstances in the discretion of the Employer. Any deferred amounts subject to a Participant’s investment election that
must be so limited, delayed or restricted under such circumstances may be notionally invested in an Investment Fund designated by the Administrator, or may be credited with earnings at a rate determined by the Administrator, which rate may be zero.
A Participant’s notional investment election shall remain in effect until later changed in accordance with the rules of the Administrator. If a Participant does not make a notional investment election, all deferrals by the Participant and
contributions on his behalf will be deemed to be notionally invested in the Investment Fund designated by the Employer for such purpose, or, at the Employer’s election, may remain uninvested until such time as the Administrator receives proper
direction, or may be credited with earnings at a rate determined by the Administrator or Employer, which rate may be zero. 
  

	 	5.3	Investment Fund Transfers 

 A Participant may elect that all or a part of his notional
interest in an Investment Fund shall be transferred to one or more of the other Investment Funds. A Participant may make such notional Investment Fund transfers in accordance with rules established from time to time by the Employer or the
Administrator, and in accordance with subsection 5.2. 

  
 - 15 - 

 SECTION 6 ACCOUNTING 

 

	 	6.1	Individual Accounts 

 Bookkeeping Accounts shall be maintained under the Plan in the name
of each Participant, as applicable, along with any subaccounts under such Accounts deemed necessary or advisable from time to time, including a subaccount for each Plan Year that a Participant’s Deferral Election is in effect. Each such
subaccount shall reflect (i) the amount of the Participant’s Deferral during that year, any Matching Contributions or Employer Contributions credited during that year, and the notional gains, losses, expenses, appreciation and depreciation
attributable thereto. 
 Rules and procedures may be established relating to the maintenance, adjustment, and liquidation of
Participants’ Accounts, the crediting of deferrals and contributions and the notional gains, losses, expenses, appreciation, and depreciation attributable thereto, as are considered necessary or advisable. 

 

	 	6.2	Adjustment of Accounts 

 Pursuant to rules established by the Employer,
Participants’ Accounts will be adjusted on each Valuation Date, except as provided in Section 9, to reflect the notional value of the various Investment Funds as of such date, including adjustments to reflect any deferrals and
contributions, notional transfers between Investment Funds, and notional gains, losses, expenses, appreciation, or depreciation with respect to such Accounts since the previous Valuation Date. The “value” of an Investment Fund at any
Valuation Date may be based on the fair market value of the Investment Fund, as determined by the Administrator in its sole discretion. 
  

	 	6.3	Accounting Methods 

 The accounting methods or formulae to be used under the Plan for
purposes of monitoring Participants’ Accounts, including the calculation and crediting of notional gains, losses, expenses, appreciation, or depreciation, shall be determined by the Administrator in its sole discretion. The accounting methods
or formulae selected by the Administrator may be revised from time to time. 
  

	 	6.4	Statement of Account 

 At such times and in such manner as determined by the
Administrator, but at least annually, each Participant will be furnished with a statement reflecting the condition of his Accounts. 

  
 - 16 - 

 SECTION 7 VESTING 

A Participant shall be fully vested at all times in his Compensation Deferral Account (if applicable). A Participant shall be vested in his
Matching Contributions and/or Employer Contributions (if applicable), in accordance with the vesting schedule elected by the Employer under the Adoption Agreement. Vesting Years of Service shall be determined in accordance with the election made by
the Employer in the Adoption Agreement. Amounts in a Participant’s Accounts that are not vested upon the Participant’s Termination Date (“forfeitures”) may be used to reinstate amounts previously forfeited by other Participants
who are subsequently rehired, or may be returned to the Employer, in the discretion of the Employer or the Administrator. 
 If a
Participant has a Termination Date with the Employer as a result of the Participant’s Misconduct (as defined by the Employer in the Adoption Agreement), or if the Participant engages in Competition with the Employer (as defined by the Employer
in the Adoption Agreement), and the Employer has so elected in the Adoption Agreement, the Participant shall forfeit all amounts allocated to his or her Matching Contribution Account and/or Employer Contribution Accounts (if applicable). Such
forfeitures shall be returned to the Employer. 
 Neither the Administrator nor the Employer in any way guarantee the Participant’s
Account balance from loss or depreciation. Notwithstanding any provision of the Plan to the contrary, the Participant’s Account balance is subject to Section 8. 

Vesting Years of Service in the event of the rehire of a Participant shall be reinstated, and amounts previously forfeited by such
Participants may be reinstated from forfeitures made by other Participants, or may be reinstated by the Employer. 

  
 - 17 - 

 SECTION 8 FUNDING 

No Participant or other person shall acquire by reason of the Plan any right in or title to any assets, funds, or property of the Employer
whatsoever, including, without limiting the generality of the foregoing, any specific funds, assets, or other property of the Employer. Benefits under the Plan are unfunded and unsecured. A Participant shall have only an unfunded, unsecured right to
the amounts, if any, payable hereunder to that Participant. The Employer’s obligations under this Plan are not secured or funded in any manner, even if the Employer elects to establish a trust with respect to the Plan. Even though benefits
provided under the Plan are not funded, the Employer may establish a trust to assist in the payment of benefits. All investments under this Plan are notional and do not obligate the Employer (or its delegates) to invest the assets of the Employer or
of any such trust in a similar manner. 

  
 - 18 - 

 SECTION 9 DISTRIBUTION OF ACCOUNTS 

 

	 	9.1	Distribution of Accounts 

 With respect to any Participant who has a Termination Date
that precedes his Retirement date, an amount equal to the Participant’s vested Account balances shall be distributed to the Participant (or, in the case of the Participant’s death, to the Participant’s Beneficiary), in the form of a
single lump sum payment, or, if subsection 9.2 applies, in the form of installment payments as designated by the Employer in the Adoption Agreement. Subject to subsection 9.3 hereof, distribution of a Participant’s Accounts shall be made or
begin within the 90-day period following the Participant’s Termination Date (provided, however, that if calculation of the amount of the payment is not administratively practicable due to events beyond
the control of the Participant, the payment will be made as soon as administratively practicable for the Administrator to make such payment). Notwithstanding any provision of the Plan to the contrary, for purposes of this subsection, a
Participant’s Accounts shall be valued as of a Valuation Date as soon as administratively feasible preceding the date such distribution is made, in accordance with rules established by the Administrator. A Participant’s Accounts may be
offset by any amounts owed by the Participant to the Employer, but such offset shall not occur in excess of or prior to the date distribution of the amount would otherwise be made to the Participant. 

Notwithstanding the foregoing, to the extent designated by the Employer in the Adoption Agreement, a Participant may elect, in accordance with
this subsection, a distribution date for his Compensation Deferral Accounts and/or his Employer Contributions and Matching Contributions Accounts that is prior to his Termination Date (an “In-Service
Distribution”). A Participant’s election of an In-Service Distribution date must: (i) be made at the time of his Deferral Election for a Plan Year; and (ii) apply only to amounts deferred
pursuant to that election, and any earnings, gains, losses, appreciation, and depreciation credited thereto or debited therefrom with respect to such amounts. To the extent permitted by the Employer, a Participant may elect an In-Service Distribution date with respect to Performance-Based Bonus Deferrals that is separate from an In-Service Distribution date with respect to Compensation Deferrals
other than Performance-Based Bonus Deferrals for the same year, provided that the applicable In-Service Distribution date may not be earlier than the number of years designated by the Employer in the Adoption
Agreement following the year in which the applicable Compensation would have been paid absent the deferral, or as further determined or limited in accordance with rules established by the Administrator. Payments made pursuant to an In-Service Distribution election shall be made in a lump sum (or, if elected by the Employer in the Adoption Agreement, any applicable other form of payment to the extent permitted by the Employer and elected by the
Participant in accordance with the terms of the Plan). Each such payment shall be made as soon as administratively feasible following January 1 of the calendar year in which the payment was elected to be made, but in no event later than the end
of the calendar year in which the payment was elected to be made (provided, however, that if calculation of the amount of the payment is not administratively practicable due to events beyond the control of the Participant, the payment will be made
as soon as administratively practicable for the Administrator to make such payment). For purposes of such payment, the value of the 

  
 - 19 - 

 
Participant’s Accounts for the applicable Plan Year shall be determined as of a Valuation Date preceding the date that such distribution is made, in accordance with rules established by the
Administrator. In the event a Participant’s Termination Date occurs (or, if elected by the Employer in the Adoption Agreement, in the event a Change in Control of the Employer occurs) prior to the date the Participant had previously elected to
have an In-Service Distribution payment made to him, such amount shall be paid to the Participant under the rules applicable for payment on Termination of Employment in accordance with this subsection 9.1 and
subsection 9.2. Participants must make an affirmative election with respect to payment of their In-Service Distributions, and no default or evergreen election shall be allowed with respect to In-Service Distributions.  
 To the extent elected by the Employer in the Adoption Agreement,
Participants whose Termination Date has not yet occurred may elect to defer payment of any In-Service Distribution, provided that such election is made in accordance with procedures established by the
Administrator, and further provided that any such election must be made no later than 12 calendar months prior to the previously elected In-Service Distribution Date (which for these purposes shall be
January 1 of the calendar year in which the payment was elected to be made). Participants may elect any deferred payment date, but such date must be no fewer than five years from the previously elected
In-Service Distribution Date (which for these purposes shall be January 1 of the calendar year in which the payment was elected to be made). 

 

	 	9.2	Installment Distributions 

 To the extent elected by the Employer in the Adoption
Agreement, a Participant may elect to receive payments from his Accounts in the form of a single lump sum, as described in Section 9.1, or in annual installments over a period elected by the Employer in the Adoption Agreement. To
the extent a Participant fails to make an election, the Participant shall be deemed to have elected to receive his distribution for that Plan Year in the form of a single lump sum. To the extent elected by the Employer in the Adoption Agreement, a
Participant may make a separate election with respect to his Performance-Based Bonus Deferrals for each year (as adjusted for gains and losses thereon) that provides for a different method of distribution from the method of distribution he elects
with respect to his Compensation Deferrals (as adjusted for gains and losses thereon) for that year. The Participant’s Employer Contributions Account attributable to such year, if any (as adjusted for gains and losses thereon), shall be
distributed in the same manner as his Compensation Deferral Account for such year (or in a lump sum upon his Termination Date if no election has been made). 
  

	 	(a)	Installment Elections. A Participant will be required to make his distribution election prior to the commencement of each calendar year (or, in the event of an election with respect to Performance-Based Bonuses,
prior to six months before the end of the applicable performance period), or such earlier date as determined by the Administrator. 

  
 - 20 - 

	 	(b)	Installment Payments. The first installment payment shall generally be within the 90-day period following the Participant’s Termination Date (provided, however, that
if calculation of the amount of the payment is not administratively practicable due to events beyond the control of the Participant, the payment will be made as soon as administratively practicable for the Administrator to make such payment).
Succeeding payments shall generally be made by January 1 of each succeeding calendar year, but in no event later than the end of each succeeding calendar year (provided, however, that if calculation of the amount of the payment is not
administratively practicable due to events beyond the control of the Participant, the payment will be made as soon as administratively practicable for the Administrator to make such payment). The amount to be distributed in each installment payment
shall be determined by dividing the value of the Participant’s Accounts being paid in installments as of a Valuation Date preceding the date of each distribution by the number of installment payments remaining to be made, in accordance with
rules established by the Administrator. In the event of the death of the Participant prior to the full payment of his Accounts being paid in installments, payments will continue to be made to his Beneficiary in the same manner and at the same time
as would have been payable to the Participant. 

 To the extent elected by the Employer in the Adoption Agreement,
Participants who have elected payment in installments may make a subsequent election to elect payment of that amount in the form of a lump sum, if payment of installments with respect to that year’s deferrals has not yet commenced. Such
election must be made in accordance with procedures established by the Administrator, and any such election must be made no later than 12 calendar months prior to the originally elected payment date of the first installment. The new payment date for
the installment with respect to which such election is made must be deferred to the later of: (i) five years from the date such payment would otherwise have been made, or (ii) the last payment date of the last installment with respect to
that year’s deferrals. To the extent elected by the Employer in the Adoption Agreement, Participants who have elected payment in installments may make a subsequent election to change the number of such installment payments so long as no
acceleration of distribution payments occurs (but no fewer than the minimum number, and not to exceed the maximum number of installments elected by the Employer in the Adoption Agreement), if payment of installments with respect to that year’s
Deferral Elections has not yet commenced. Such election must be made in accordance with procedures established by the Administrator, and any such election must be made no later than 12 calendar months prior to the originally elected payment date of
the first installment. The new payment date for any installment with respect to which such election is made must be deferred for a period of not less than five years from the date such payment would otherwise have been made. In the event payment has
been elected by the Participant in the form of installments (to the extent elected by the Employer in the Adoption Agreement), each installment payment shall be considered a separately identifiable payment. In the event payment has been elected by
the Participant in the form of a lump sum (or in the event payment shall be made to the Participant in the form of a lump sum under the terms of the Plan in the absence of or in lieu of the Participant’s election), then the lump sum form shall
be deemed to be a separately identifiable form of payment, and the Participant may make a subsequent deferral election to elect payment of that amount in the form of installments (to the extent elected by the Employer in the Adoption Agreement) in
accordance with the procedures described above for changing installment payment elections. Participants will be permitted to make such a change only once with respect to any year’s Deferral Elections.

	 	9.3	Key Employees 

 Notwithstanding anything herein to the contrary, and subject to Code
Section 409A, except in the case of the Participant’s death, payment under the Plan shall not be made or commence as a result of the Participant’s Termination Date to any Participant who is a key employee (defined below) before the
date that is not less than six months after the Participant’s Termination Date. For this purpose, a key employee includes a “specified employee” (as defined in Treasury Regulation
Section 1.409A-1(i)) during the entire 12-month period determined by the Administrator ending with the annual date upon which key employees are identified by the
Administrator, and also including any Employee identified by the Administrator in good faith with respect to any distribution as belonging to the group of identified key employees, to a maximum of 200 such key employees, regardless of whether such
Employee is subsequently determined by the Employer, any governmental agency, or a court not to be a key employee. In the event amounts are payable to a key employee in installments in accordance with subsection 9.2, the first installment shall be
delayed by six months, with all other installment payments payable as originally scheduled. To the extent not otherwise designated by the Employer in a separate document forming a part of the Plan applicable to all its nonqualified deferred
compensation plans, the identification date for determining the Employer’s key employees is each December 31 (and the new key employee list is updated and effective each subsequent April 1). To the extent not otherwise designated by the
Employer in a separate document forming a part of the Plan, the definition of compensation used to determine key employee status shall be determined under Treasury Regulation Section 1.415(c)-2(a). This
subsection 9.3 is applicable only with respect to Employers whose stock is publicly traded on an “established securities market” (as defined in Treasury Regulation Section 1.409A-1(k)), and is
not applicable to privately held Employers unless and until such Employers become publicly traded as defined in the Treasury regulations. 
  

	 	9.4	Mandatory Cash-Outs of Small Amounts 

 If the value of a Participant’s total
Accounts at his Termination Date (or his death or other applicable distribution date), or at any time thereafter, together with the value of the Participant’s accounts under any other account balance plan maintained by the Employer or any
member of the Employer’s controlled group (as defined in subsections 414(b) and (c) of the Code) is equal to or less than such amount as stated in the Adoption Agreement (which amount shall not exceed the limit described in
Section 402(g) of the Code from time to time), the Accounts will be paid to the Participant (or, in the event of his death, his Beneficiary) in a single lump sum, notwithstanding any election by the Participant otherwise. Payments made under
this subsection 9.4 on account of the Participant’s Termination Date shall be made within the 90-day period following the Participant’s Termination Date (provided, however, that if calculation of the
amount of the payment is not administratively practicable due to events beyond the control of the Participant, the payment will be made as soon as administratively practicable for the Administrator to make such payment). 

  
 - 22 - 

	 	9.5	Designation of Beneficiary 

 Each Participant from time to time may designate any
individual, trust, charity or other person or persons to whom the value of the Participant’s Accounts (plus any applicable Survivor Benefit, if elected by the Employer in the Adoption Agreement) will be paid in the event the Participant dies
before receiving the value of all of his Accounts. A Beneficiary designation must be made in the manner required by the Administrator for this purpose. Primary and secondary Beneficiaries are permitted. A married participant designating a
Beneficiary other than his Spouse must obtain the consent of his Spouse to such designation (in accordance with rules determined by the Administrator). Payments to the Participant’s Beneficiary(ies) shall be made in accordance with subsection
9.1, 9.2 or 9.4, as applicable, after the Administrator has received proper notification of the Participant’s death. 
 A Beneficiary
designation will be effective only when the Beneficiary designation is filed with the Administrator while the Participant is alive, and a subsequent Beneficiary designation will cancel all of the Participant’s Beneficiary designations
previously filed with the Administrator. Any designation or revocation of a Beneficiary shall be effective as only if it is received by the Administrator. Once received, such designation shall be effective as of the date the designation was
executed, but without prejudice to the Administrator on account of any payment made before the change is recorded by the Administrator. If a Beneficiary dies before payment of the Participant’s Accounts have been made, the Participant’s
Accounts shall be distributed in accordance with the Participant’s Beneficiary designation and pursuant to rules established by the Administrator. If a deceased Participant failed to designate a Beneficiary, or if the designated Beneficiary
predeceases the Participant, the value of the Participant’s Accounts shall be payable to the Participant’s Spouse or, if there is none, to the Participant’s estate, or in accordance with such other equitable procedures as determined
by the Administrator. 
  

	 	9.6	Reemployment 

 If a former Participant is rehired by an Employer, or any affiliate or
subsidiary of the Employer described in Section 414(b) and (c) of the Code and Treasury Regulation Section 1.409A-1(h), regardless of whether he is rehired as an Eligible Individual (with
respect to an Employee Participant), or a former Participant returns to service as a Board member, any payments being made to such Participant hereunder by virtue of his previous Termination Date shall continue to be made to him without regard to
such rehire. If a former Participant is rehired by the Employer (with respect to an Employee Participant) or returns to service as a Board member, and in either case any payments to be made to the Participant by virtue of his previous Termination
Date have not been made or commenced, any payments being made to such Participant hereunder by virtue of his previous Termination Date shall continue to be made to him without regard to such rehire or return to service. See subsections 4.1 and 4.2
of the Plan for special rules applicable to deferral elections for rehired or Re-Eligible Participants. 

  
 - 23 - 

	 	9.7	Special Distribution Rules 

 Except as otherwise provided herein and in Section 12,
Account balances of Participants in this Plan shall not be distributed earlier than the applicable date or dates described in this Section 9. Notwithstanding the foregoing, in the case of payments: (i) the deduction for which would be
limited or eliminated by the application of Section 162(m) of the Code; (ii) that would violate securities or other applicable laws; or (iii) that would jeopardize the ability of the Employer to continue as a going concern in
accordance with Code Section 409A and the regulations thereunder, deferral of such payments on a reasonably consistent basis for similarly situated Participants may be made by the Employer at the Employer’s discretion. In the case of a
payment described in (i) above, the payment must be deferred either to a date in the first year in which the Employer or Administrator reasonably anticipates that a payment of such amount would not result in a limitation of a deduction with
respect to the payment of such amount under Section 162(m), or the year in which the Participant’s Termination Date occurs. In the case of a payment described in (ii) or (iii) above, payment will be made at the earliest date in the
first taxable year of the Employer in which the Employer or Administrator reasonably anticipates that the payment would not jeopardize the ability of the Employer to continue as a going concern in accordance with Code Section 409A and the
regulations thereunder, or the payment would not result in a violation of securities or other applicable laws. Payments intended to pay employment taxes or payments made as a result of income inclusion of an amount in a Participant’s Accounts
as a result of a failure to satisfy Section 409A of the Code shall be permitted at the Employer or Administrator’s discretion at any time and to the extent provided in Treasury Regulations under Section 409A of the Code and IRS Notice
2005-1, Q&A-15, and any applicable subsequent guidance. “Employment taxes” shall include Federal Insurance Contributions Act (FICA) tax imposed under
Sections 3101, 3121(a) and 3121(v)(2) of the Code on compensation deferred under the Plan (the “FICA Amount”), the income tax imposed under Section 3401 of the Code or corresponding provisions of applicable state, local or foreign tax
laws on the FICA Amount, and to pay the additional income tax under Section 3401 of the Code or corresponding provisions of applicable state, local or foreign tax laws attributable to the pyramiding Section 3401 wages and taxes. A
distribution may be accelerated as may be necessary to comply with certain conflict of interest rules in accordance with Treasury Regulation Section 1.409A-3(j)(4)(iii). With respect to a subchapter S
corporation, a distribution may be accelerated to avoid a nonallocation year under Code Section 409(p) in the discretion of the Employer or Administrator, provided that the amount distributed does not exceed 125 percent of the minimum
amount of distribution necessary to avoid the occurrence of a nonallocation year, in accordance with Treasury Regulation Section 1.409A-3(j)(4)(x). 

 

	 	9.8	Distribution on Account of Unforeseeable Emergency 

 If elected by the Employer in the
Adoption Agreement, if a Participant or Beneficiary incurs a severe financial hardship of the type described below, he may request an Unforeseeable Emergency Withdrawal, provided that the withdrawal is necessary in light of severe financial needs of
the Participant. To the extent elected by the Employer in the Adoption Agreement, the ability to apply for an Unforeseeable Emergency Withdrawal may be restricted to Participants whose Termination Date has not yet occurred. Such a withdrawal shall
not exceed the amount required (including anticipated taxes on the withdrawal) to meet the severe financial need and not reasonably available from other resources of the Participant (including reimbursement or compensation by insurance, cessation of
deferrals under this Plan for the remainder of the Plan Year, and liquidation of the Participant’s assets, to the extent liquidation itself would not cause 

  
 - 24 - 

 
severe financial hardship; provided, however, that the Participant is not required to take into account for these purposes any available distribution or loan from a qualified plan or another
nonqualified deferred compensation plan). Each such withdrawal election shall be made at such time and in such manner as the Administrator shall determine, and shall be effective in accordance with such rules as the Administrator shall establish and
publish from time to time. Severe financial needs are limited to amounts necessary for: 
  

	 	(a)	A sudden unexpected illness or accident incurred by the Participant, his Spouse, Beneficiary under the Plan, or dependents (as defined in Code Section 152(a)). 

 

	 	(b)	Uninsured casualty loss pertaining to property owned by the Participant. 

  

	 	(c)	Other similar extraordinary and unforeseeable circumstances involving an uninsured loss arising from an event outside the control of the Participant. 

Withdrawals of amounts under this subsection shall be paid to the Participant in a lump sum as soon as administratively feasible following receipt of the
appropriate forms and information required by and acceptable to the Administrator. 
  

	 	9.9	Distribution Upon Change in Control 

 In the event of the occurrence of a Change in
Control of the Employer or a member of the Employer’s controlled group (as designated by the Employer in the Adoption Agreement) to the extent permitted under Section 409A of the Code and the regulations and other guidance thereunder,
distributions shall be made to Participants to the extent elected by the Employer in the Adoption Agreement, in the form elected by the Participants as if a Termination Date had occurred with respect to each Participant, or as otherwise specified by
the Employer in the Adoption Agreement. The Change in Control shall relate to: (i) the corporation for whom the Participant is performing services at the time of the Change in Control event; (ii) the corporation that is liable for the
payment from the Plan to the Participant (or all corporations so liable if more than one corporation is liable); (iii) a corporation that is a majority shareholder of a corporation described in (i) or (ii) above; or (iv) any corporation in
a chain of corporations in which each such corporation is a majority shareholder of another corporation in the chain, ending in a corporation described in (i) or (ii) above, as elected by the Employer in the Adoption Agreement. A “majority
shareholder” for these purposes is a shareholder owning more than 50% of the total fair market value and total voting power of such corporation. Attribution rules described in section 318(a) of the Code apply to determine stock ownership. Stock
underlying a vested option is considered owned by the individual who holds the vested option. Notwithstanding the foregoing, if a vested option is exercisable for stock that is not substantially vested (as defined in section 1.83-3(b) and (j) of the Code), the stock underlying the option is not treated as owned by the individual who holds the option. If plan payments are made on account of a Change in Control and are calculated by
reference to the value of the Employer’s stock, such payments shall be completed not later than 5 years after the Change in Control event. To the extent designated by the Employer in the Adoption Agreement, the Change in Control shall occur
upon the date that: (v) a person or “Group” (as defined in Treasury Regulation Sections 1.409A-3(i)(5)(v)(B) and (vi)(D)) acquires more than 50% of the total fair market value or voting power

  
 - 25 - 

 
of stock of the corporation designated in (i) through (iv) above; (vi) a person or Group acquires ownership (“effective control”) of stock of the corporation with at least 30%
of the total voting power of the corporation designated in (i) through (iv) above and as further limited by Treasury Regulation Section 1.409A-3(i)(5)(vi)); (vii) a majority of the board of directors
of any corporation designated in (i) through (iv) above in which no other corporation is a majority shareholder is replaced during any 12-month period by directors whose appointment or election is not
endorsed by a majority of the board as constituted prior to the appointment or election; or (viii) a person or Group acquires assets from the corporation designated in (i) through (iv) above having a total fair market value of at least 40%
of the value of all assets of the corporation immediately prior to such acquisition; as designated by the Employer in the Adoption Agreement. For purposes of (vi) above, if any one person, or more than one person acting as a Group, is
considered to own more than 50 percent of the total fair market value or total voting power of the stock of a corporation, the acquisition of additional stock by the same person or persons is not considered to cause a change in the ownership of
the corporation (or to cause a change in the effective control of the corporation under (vi) above). An increase in the percentage of stock owned by any one person, or persons acting as a Group, as a result of a transaction in which the
corporation acquires its stock in exchange for property will be treated as an acquisition of stock for purposes of this subsection. For purposes of (v) through (viii) above, a Change in Control shall be further limited in accordance with
Treasury Regulation Sections 1.409A-3(i)(5)(v), (vi) and (vii). Distributions under this subsection shall be made as soon as administratively feasible following such Change in Control. 

 

	 	9.10	Supplemental Survivor Death Benefit 

 A supplemental survivor death benefit shall be paid
to the Beneficiary of an eligible Participant who has satisfied the following criteria prior to his death: 
  

	 	(a)	The Participant is eligible to participate in the Plan and, at the time of his death, had a current Account balance (regardless of whether or not the Participant actually was making Compensation Deferrals at the time of
his death); 

  

	 	(b)	The Participant was an active Employee with the Employer at the time of his death; 

  

	 	(c)	The Participant completed and submitted an insurance application to the Administrator; and 

  

	 	(d)	The Employer subsequently purchased an insurance policy on the life of the Participant, with a death benefit payable, which policy is in effect at the time of the Participant’s death. 

Notwithstanding any provision of this Plan or any other document to the contrary, the supplemental survivor death benefit payable pursuant to this
Subsection 9.10 shall be paid only if an insurance policy has been issued on the Participant’s life and such policy is in force at the time of the Participant’s death and the Employer shall have no obligation with respect to the
payment of the supplemental survivor death benefit, or to maintain an insurance policy for any Participants.

 SECTION 10 GENERAL PROVISIONS 

 

	 	10.1	Interests Not Transferable 

 The interests of persons entitled to benefits under the Plan
are not subject to their debts or other obligations and, except as may be required by the tax withholding provisions of the Code or any state’s income tax act, may not be voluntarily or involuntarily sold, transferred, alienated, assigned, or
encumbered; provided, however, that a Participant’s interest in the Plan may be transferable pursuant to a qualified domestic relations order, as defined in Section 414(p) of the Code to the extent designated by the Employer in the
Adoption Agreement. 
  

	 	10.2	Employment Rights 

 The Plan does not constitute a contract of employment, and
participation in the Plan shall not give any Employee the right to be retained in the employ of an Employer, nor any right or claim to any benefit under the Plan, unless such right or claim has specifically accrued under the terms of the Plan. The
Employer expressly reserves the right to discharge any Employee at any time. 
  

	 	10.3	Litigation by Participants or Other Persons 

 If a legal action begun against the
Administrator (or any member or former member thereof), an Employer, or any person or persons to whom an Employer or the Administrator has delegated all or part of its duties hereunder, by or on behalf of any person results adversely to that person,
or if a legal action arises because of conflicting claims to a Participant’s or other person’s benefits, the cost to the Administrator (or any member or former member thereof), the Employer or any person or persons to whom the Employer or
the Administrator has delegated all or part of its duties hereunder of defending the action may be charged to the extent permitted by law to the sums, if any, which were involved in the action or were payable to the Participant or other person
concerned. 
  

	 	10.4	Indemnification 

 To the extent permitted by law, the Employer shall indemnify each
member of the Administrator committee, and any other employee or member of the Board with duties under the Plan, against losses and expenses (including any amount paid in settlement) reasonably incurred by such person in connection with any claims
against such person by reason of such person’s conduct in the performance of duties under the Plan, except in relation to matters as to which such person has acted fraudulently or in bad faith in the performance of duties. Notwithstanding the
foregoing, the Employer shall not indemnify any person for any expense incurred through any settlement or compromise of any action unless the Employer consents in writing to the settlement or compromise. 

  
 - 28 - 

	 	10.5	Evidence 

 Evidence required of anyone under the Plan may be by certificate, affidavit,
document, or other information which the person acting on it considers pertinent and reliable, and signed, made, or presented by the proper party or parties. 
  

	 	10.6	Waiver of Notice 

 Any notice required under the Plan may be waived by the person
entitled to such notice. 
  

	 	10.7	Controlling Law 

 Except to the extent superseded by laws of the United States, the laws
of the state indicated by the Employer in the Adoption Agreement shall be controlling in all matters relating to the Plan. 
  

	 	10.8	Statutory References 

 Any reference in the Plan to a Code section or a section of ERISA,
or to a section of any other Federal law, shall include any comparable section or sections of any future legislation that amends, supplements, or supersedes that section. 
  

	 	10.9	Severability 

 In case any provision of the Plan shall be held illegal or invalid for any
reason, such illegality or invalidity shall not affect the remaining provisions of the Plan, and the Plan shall be construed and enforced as if such illegal and invalid provision had never been set forth in the Plan. 

 

	 	10.10	Action By the Employer or the Administrator 

 Any action required or permitted to be
taken by the Employer under the Plan shall be by resolution of its Board of Directors (which term shall include any similar governing body for any Employer that is not a corporation), by resolution or other action of a duly authorized committee of
its Board of Directors, or by action of a person or persons authorized by resolution of its Board of Directors or such committee. Any action required or permitted to be taken by the Administrator under the Plan shall be by resolution or other action
of the Administrator or by a person or persons duly authorized by the Administrator. 
  

	 	10.11	Headings and Captions 

 The headings and captions contained in this Plan are inserted
only as a matter of convenience and for reference, and in no way define, limit, enlarge, or describe the scope or intent of the Plan, nor in any way shall affect the construction of any provision of the Plan. 

  
 - 29 - 

	 	10.12	Gender and Number 

 Where the context permits, words in the masculine gender shall
include the feminine and neuter genders, the singular shall include the plural, and the plural shall include the singular. 
  

	 	10.13	Examination of Documents 

 Copies of the Plan and any amendments thereto are on file at
the office of the Employer where they may be examined by any Participant or other person entitled to benefits under the Plan during normal business hours. 
  

	 	10.14	Elections 

 Each election or request required or permitted to be made by a Participant
(or a Participant’s Spouse or Beneficiary) shall be made in accordance with the rules and procedures established by the Employer or Administrator and shall be effective as determined by the Administrator. The Administrator’s rules and
procedures may address, among other things, the method and timing of any elections or requests required or permitted to be made by a Participant (or a Participant’s Spouse or Beneficiary). All elections under the Plan shall comply with the
requirements of the Uniformed Services Employment and Reemployment Rights Act of 1994, as amended (“USERRA”). 
  

	 	10.15	Manner of Delivery 

 Each notice or statement provided to a Participant shall be
delivered in any manner established by the Administrator and in accordance with applicable law, including, but not limited to, electronic delivery. 
  

	 	10.16	Facility of Payment 

 When a person entitled to benefits under the Plan is a minor, under
legal disability, or is in any way incapacitated so as to be unable to manage his financial affairs, the Administrator may cause the benefits to be paid to such person’s guardian or legal representative. If no guardian or legal representative
has been appointed, or if the Administrator so determines in its sole discretion, payment may be made to any person as custodian for such individual under any applicable state law, or to the legal representative of such person for such person’s
benefit, or the Administrator may direct the application of such benefits for the benefit of such person. Any payment made in accordance with the preceding sentence shall be a full and complete discharge of any liability for such payment under the
Plan. 
  

	 	10.17	Missing Persons 

 The Employer and the Administrator shall not be required to search for
or locate a Participant, Spouse, or Beneficiary. Each Participant, Spouse, and Beneficiary must file with the Administrator, from time to time, in writing the Participant’s, Spouse’s, or Beneficiary’s post office address and each
change of post office address. Any communication, statement, or notice 

  
 - 30 - 

 
addressed to a Participant, Spouse, or Beneficiary at the last post office address filed with the Administrator, or if no address is filed with the Administrator, then in the case of a
Participant, at the Participant’s last post office address as shown on the Employer’s records, shall be considered a notification for purposes of the Plan and shall be binding on the Participant and the Participant’s Spouse and
Beneficiary for all purposes of the Plan. 
 If the Administrator is unable to locate the Participant, Spouse, or Beneficiary to whom a
Participant’s Accounts are payable, the Participant’s Accounts shall be frozen as of the date on which distribution would have been completed under the terms of the Plan, and no further notional investment returns shall be credited
thereto. 
 If a Participant whose Accounts were frozen (or his Beneficiary) files a claim for distribution of the Accounts within 7 years
after the date the Accounts are frozen, and if the Administrator or Employer determines that such claim is valid, then the frozen balance that has become payable shall be paid by the Employer to the Participant or Beneficiary in a lump sum cash
payment as soon as practicable thereafter. If the Administrator notifies a Participant, Spouse, or Beneficiary of the provisions of this Subsection, and the Participant, Spouse, or Beneficiary fails to claim the Participant’s, Spouse’s, or
Beneficiary’s benefits or make such person’s whereabouts known to the Administrator within 7 years after the date the Accounts are frozen, the benefits of the Participant, Spouse, or Beneficiary may be disposed of, to the extent permitted
by applicable law, by one or more of the following methods: 
  

	 	(a)	By retaining such benefits in the Plan. 

  

	 	(b)	By paying such benefits to a court of competent jurisdiction for judicial determination of the right thereto. 

  

	 	(c)	By forfeiting such benefits in accordance with procedures established by the Administrator. If a Participant, Spouse, or Beneficiary is subsequently located, such benefits may be restored (without adjustment) to the
Participant, Spouse, or Beneficiary under the Plan. 

  

	 	(d)	By any equitable manner permitted by law under rules adopted by the Administrator. 

  

	 	10.18	Recovery of Benefits 

 In the event a Participant, Spouse, or Beneficiary receives a
benefit payment from the Plan that is in excess of the benefit payment that should have been made to such Participant, Spouse, or Beneficiary, or in the event a person other than a Participant, Spouse, or Beneficiary receives an erroneous payment
from the Plan, the Administrator or Employer shall have the right, on behalf of the Plan, to recover the amount of the excess or erroneous payment from the recipient. To the extent permitted under applicable law, the Administrator or Employer may,
at its option, deduct the amount of such excess or erroneous payment from any future benefits payable to the applicable Participant, Spouse, or Beneficiary. 

  
 - 31 - 

	 	10.19	Effect on Other Benefits 

 Except as otherwise specifically provided under the terms of
any other employee benefit plan of the Employer, a Participant’s participation in this Plan shall not affect the benefits provided under such other employee benefit plan. 

 

	 	10.20	Tax and Legal Effects 

 The Employer, the Administrator, and their representatives and
delegates do not in any way guarantee the tax treatment of benefits for any Participant, Spouse, or Beneficiary, and the Employer, the Administrator, and their representatives and delegates do not in any way guarantee or assume any responsibility or
liability for the legal, tax, or other implications or effects of the Plan. In the event of any legal, tax, or other change that may affect the Plan, the Employer may, in its sole discretion, take any actions it deems necessary or desirable as a
result of such change. 

  
 - 32 - 

 SECTION 11 THE ADMINISTRATOR 

 

	 	11.1	Information Required by Administrator 

 Each person entitled to benefits under the Plan
must file with the Administrator from time to time in writing such person’s mailing address and each change of mailing address. Any communication, statement, or notice addressed to any person at the last address filed with the Administrator
will be binding upon such person for all purposes of the Plan. Each person entitled to benefits under the Plan also shall furnish the Administrator with such documents, evidence, data, or information as the Administrator considers necessary or
desirable for the purposes of administering the Plan. The Employer shall furnish the Administrator with such data and information as the Administrator may deem necessary or desirable in order to administer the Plan. The records of the Employer as to
an Employee’s or Participant’s period of employment or membership on the Board, termination of employment or membership and the reason therefor, leave of absence, reemployment, and Compensation will be conclusive on all persons unless
determined to the Administrator’s or Employer’s satisfaction to be incorrect. 
  

	 	11.2	Uniform Application of Rules 

 The Administrator shall administer the Plan on a
reasonable basis. Any rules, procedures, or regulations established by the Administrator shall be applied uniformly to all persons similarly situated. 
  

	 	11.3	Review of Benefit Determinations 

 Benefits will be paid to Participants and their
beneficiaries without the necessity of formal claims. Participants or their beneficiaries, however, may make a written request to the Administrator for any Plan benefits to which they may be entitled. Participants’ written request for Plan
benefits will be considered a claim for Plan benefits, and will be subject to a full and fair review. If the claim is wholly or partially denied, the Administrator will furnish the claimant with a written notice of this denial. This written notice
will be provided to the claimant within 90 days after the receipt of the claim by the Administrator. If notice of the denial of a claim is not furnished to the claimant in accordance with the above within 90 days, the claim will be deemed denied.
The claimant will then be permitted to proceed to the review stage described in the following paragraphs. 
 Upon the denial of the claim
for benefits, the claimant may file a claim for review, in writing, with the Administrator. The claim for review must be filed no later than 60 days after the claimant has received written notification of the denial of the claim for benefits or, if
no written denial of the claim was provided, no later than 60 days after the deemed denial of the claim. The claimant may review all pertinent documents relating to the denial of the claim and submit any issues and comments, in writing, to the
Administrator. If the claim is denied, the Administrator must provide the claimant with written notice of this denial within 60 days after the Administrator’s receipt of the claimant’s written claim for review. The Administrator’s
decision on the claim for review will be communicated to the claimant in writing and will include specific references to the pertinent Plan provisions on which the decision was based. If 

  
 - 33 - 

 
the Administrator’s decision on review is not furnished to the claimant within the time limitations described above, the claim will be deemed denied on review. If the claim for Plan benefits
is finally denied by the Administrator (or deemed denied), then the claimant may bring suit in federal court. The claimant may not commence a suit in a court of law or equity for benefits under the Plan until the Plan’s claim process and appeal
rights have been exhausted and the Plan benefits requested in that appeal have been denied in whole or in part. However, the claimant may only bring a suit in court if it is filed within 90 days after the date of the final denial of the claim by the
Administrator. 
 With respect to claims for benefits payable as a result of a Participant being determined to be disabled, the
Administrator will provide the claimant with notice of the status of his claim for disability benefits under the Plan within a reasonable period of time after a complete claim has been filed, but no later than 45 days after receipt of the claim for
benefits. The Administrator may request an additional 30-day extension if special circumstances warrant by notifying the claimant of the extension before the expiration of the initial 45-day period. If a decision still cannot be made within this 30-day extension period due to circumstances outside the Plan’s control, the time period may be extended for
an additional 30 days, in which case the claimant will be notified before the expiration of the original 30-day extension. 

If the claimant has not submitted sufficient information to the Administrator to process his disability benefit claim, he will be notified of
the incomplete claim and given 45 days to submit additional information. This will extend the time in which the Administrator has to respond to the claim from the date the notice of insufficient information is sent to the claimant until the date the
claimant responds to the request. If the claimant does not submit the requested missing information to the Administrator within 45 days of the date of the request, the claim will be denied. 

If a disability benefit claim is denied, the claimant will receive a notice which will include: (i) the specific reasons for the denial,
(ii) reference to the specific Plan provisions upon which the decision is based, (iii) a description of any additional information the claimant might be required to provide with an explanation of why it is needed, and (iv) an

 SECTION 12 AMENDMENT AND TERMINATION 

While the Employer expects and intends to continue the Plan, the Employer and the Administrator each reserve the right to amend the Plan at any
time and for any reason, including the right to amend this Section 12 and the Plan termination rules herein; provided, however, that each Participant will be entitled to the amount credited to his Accounts immediately prior to such amendment.
The power to amend the Plan includes (without limitation) the power to change the Plan provisions regarding eligibility, contributions, notional investments, vesting, and distribution forms, and timing of payments, including changes applicable to
benefits accrued prior to the effective date of any such amendment; provided, however, that amendments to the Plan (other than amendments relating to Plan termination) shall not cause the Plan to provide for acceleration of distributions in

 The Employer reserves the right to terminate the Plan
at any time and for any reason; provided, however, that each Participant will be entitled to the amount credited to his Accounts immediately prior to such termination (as adjusted for notional income, losses, expenses, appreciation and depreciation
occurring from the date of such termination until the date of distribution). 
 In the event that the Plan is terminated pursuant to this
Section 12, the balances in affected Participants’ Accounts shall be distributed at the time and in the manner set forth in Section 9. Notwithstanding the foregoing, the Employer and the Administrator reserve the right to make all
such distributions within the second twelve-month period commencing with the date of termination of the Plan; provided, however, that no such distribution will be made during the first twelve-month period following such date of Plan termination
other than those that would otherwise be payable under Section 9 absent the termination of the Plan. In the event of a Plan termination due to a Change in Control of the Employer, distributions shall be made within 12 months of the date of the
