Executive’s written notice.

Employers’ Boards of Directors. The Boards of Directors, if warranted in their sole discretion, may increase Executive’s Base Salary to reflect Executive’s performance. The Boards of Directors, if warranted in their sole discretion,

Employers’ Boards of Directors, Executive shall serve on the Boards of Directors of the Employers. 
 (f) Resignation
from the Board of Directors. If Executive’s employment with the Employers is terminated for any reason, or if Executive resigns from his Employers employment for any reason, then Executive agrees that he shall tender his resignation from
the Boards of Directors of the Employers and any company affiliated with the Employers on which Executive serves as a director at the time of his employment termination or resignation. The decision whether to accept such resignation shall be within

 (b) Health and Welfare Benefit Plans. During the term of Executive’s
employment under this Agreement, Executive and/or Executive’s family, as the case may be, shall be eligible for participation in and shall receive all benefits under any health and welfare benefit plans, practices, policies and programs
provided by the Employers, to the extent applicable generally to senior executive officers of the Employers and subject to the terms, conditions, and eligibility requirements therefore as may be prescribed by the Employers from time to time. 

(c) Vacation and Sick Leave. Executive shall be entitled, without loss of pay, to be voluntarily absent from work or the
performance of his work duties under this Agreement as recited below, all voluntary absences to count as vacation time, provided that: 

(i) Executive shall be entitled to not less than 4 weeks of annual paid vacation or the amount of vacation in accordance with
the policies that the Boards of Directors of the Employers periodically establish for senior management employees of the Employers. 

(ii) Executive shall not receive any additional compensation from the Employers on account of his failure to take a vacation,
and Executive shall not accumulate unused vacation from one fiscal year to the next, except as authorized by the Employers’ Boards of Directors. 

(iii) In addition to paid vacations under this Agreement, Executive shall be entitled, without loss of pay, to be voluntarily
absent from work under this Agreement for such additional periods of time and for such valid and legitimate reasons as the Boards of Directors of the Employers may in their discretion approve. It is also provided that the Boards of Directors of the

 6. Benefits Payable Upon Disability. 

(a) Disability Benefits. In the event of the Disability of Executive, the Employers shall continue to pay Executive 100%
of Executive’s then current Base Salary pursuant to paragraph 4(a) during the first twelve (12) months of a substantially continuous period of Disability. It is provided, however, that in the event Executive is disabled for a substantially
continuous period exceeding twelve (12) months, the Employers may, at their election, terminate this Agreement, in which event payment of Executive’s Base Salary shall cease. 

  
 6 








 (b) Disability Benefit Offset. Any amounts payable under Agreement
paragraph 6(a) shall be reduced by any amounts paid to Executive under any other disability program or policy of insurance maintained by the Employers. 

7. Payments to Executive Upon Termination of Employment. The Boards of Directors of the Employers may terminate Executive’s
employment under this Agreement at any time, but any termination other than Termination for Cause shall not prejudice Executive’s right to compensation or other benefits under this Agreement. Executive may voluntarily terminate his employment
under this Agreement. The rights and obligations of the Employers and Executive in the event of employment termination are set forth in this Agreement paragraph 7 as follows: 

(a) Termination for Cause. Following the Executive’s termination for Cause, the Employers shall pay the Executive
any accrued but unpaid Base Salary through the date of termination of Executive’s employment and any earned but unpaid cash bonuses for any prior period. Executive shall have no right to other compensation or benefits (except for vested
benefits under any employee benefit plan and any right to continued health coverage under COBRA or similar state law) for any period after a Termination for Cause, and all outstanding, unvested equity and shares/units associated with outstanding
performance cycles and all options will be cancelled. For purposes of this Agreement, Termination for Cause which shall be determined by the Employers’ Boards of Directors, in the reasonable exercise of its discretion and acting in good faith,
is a termination of Executive’s employment as a result of Executive’s dishonesty, willful misconduct, incarceration for ten or more days, breach of fiduciary duties; intentional failure to perform his job duties; willful violation of any
law (other than minor traffic violations or less serious offenses), or a final cease-and-desist order; the regulatory suspension or removal of Executive as defined in Agreement paragraphs 8(a) and 8(b); Executive’s failure or refusal to follow
instructions of the President and Chief Executive Officer or the Boards of Directors of the Employers; or Executive’s material breach of any provision of this Agreement. The termination of Executive’s employment shall not be a Termination
for Cause unless and until there shall have been delivered to Executive a copy of a resolution duly adopted in good faith by the affirmative vote of not less than two-thirds of the membership of the Employers’ Boards of Directors at a meeting
of the Boards called and held for such purpose (after at least fifteen (15) days prior written notice of such meeting and the Executive’s alleged improper conduct is communicated to Executive and Executive is given an opportunity to be
heard before the Boards of Directors), finding that Executive is guilty of the conduct described as Termination for Cause and specifying in detail the grounds for its decision, and further that the specified conduct remains uncured or was not
capable of cure. The Employers’ Boards of Directors, in their discretion, may place Executive on a paid leave of absence for all or any portion of the period of time from the delivery of the written notice described in this Agreement until the
effective date of the Termination for Cause, or the date on which Executive returns to work from a paid leave of absence. 

(b) Event of Termination Without Change of Control. Upon the occurrence of an Event of Termination, other than for Cause
as provided in paragraph 7(a) or after a Change of Control as provided in Agreement paragraph 7(c), and if Executive faithfully 

  
 7 








 
and fully abides by all of the covenants contained in Agreement paragraph 9, the Employers shall pay to Executive, or in the event of his subsequent death, to his designated beneficiary or
beneficiaries, or to his estate, as the case may be, as liquidated damages, in lieu of all other claims, any accrued but unpaid Base Salary through the date of termination of Executive’s employment, any earned but unpaid cash bonuses for any
prior period, and equity, including long term incentive performance plans, governed in accordance with the terms of the award agreement. In addition, Employers shall pay Executive a severance payment equal to Executive’s Base Salary plus Target
Bonus with (i) the then-current Base Salary Component of said Severance Payment to be paid in equal monthly installments (each in the amount of the current annual Base Salary divided by 12) and in accordance with Employers’ regular payroll
practices, for the greater of twelve (12) months following the date of said Event of Termination or the balance of the Employment Term then in effect (“Severance Period”) and (ii) any Incentive Compensation component of said
severance payment to be paid in a lump sum within thirty (30) days after expiration of the Severance Period. In addition, the Employers shall reimburse an amount equal to the Employers’ portion of the health insurance premiums then paid
for active employees for the level of coverage elected by the Executive pursuant to COBRA until the earlier of the expiration of the Severance Period or the date on which Executive receives substantially comparable coverage and benefits under the
group health plans of a subsequent employer. In return for the severance payment described in this Agreement paragraph 7(b), Executive shall agree to execute a full release and waiver (substantially similar to the Release and Waiver attached hereto
as Exhibit “A” and made a part of this Agreement) of all known or unknown claims or causes of action Executive has, had, or may have against the Employers, except that such release shall not apply to (i) any rights of the Executive to
indemnification under the Employers’ Certificate of Incorporation or By-Laws or written agreement or to directors’ and officers’ liability insurance coverage of the Employers and its affiliates, (ii) any rights to the severance
pay or benefits under this Agreement, (iii) any rights to vested tax-qualified retirement benefits, and (iv) any rights to continued group health coverage under COBRA or applicable state law. The severance payments described in clause
(i) above shall commence within 60 days following the Executive’s termination of employment provided the Executive has executed the release and the release has become irrevocable before then. If the 60-day period described in the
immediately preceding sentence begins in one calendar year and ends in a later calendar year, the payments shall commence in the later calendar year even if the Executive executes the release and it becomes irrevocable in the earlier calendar year.
If the Executive does not execute the release and the release does not become irrevocable before the 60th day after the Executive’s termination of employment, the Executive shall not receive the severance payment described in this Agreement
paragraph 7(b). 
 (c) Event of Termination in Connection With a Change of Control. If, during the term of
Executive’s employment under this Agreement and within eighteen (18) months immediately following a Change of Control or within three months immediately prior to such Change of Control, Executive’s employment with the Employers under
this Agreement is terminated by an Event of Termination and if Executive faithfully and fully abides by all of the covenants contained in this Agreement paragraph 9, then the Employers shall pay to Executive, or in the event of his subsequent death,
to his 

  
 8 








 
designated beneficiary or beneficiaries, or to his estate, as the case may be, as liquidated damages, in lieu of all other claims and payments under this Agreement, a severance payment equal to
2.25 times the sum of Executive’s Base Salary plus Target Bonus (equal to his Base Salary multiplied by his annual incentive Target Bonus percentage, each as then in effect), pro-rated over a period of thirty (30) months following the date
of said Event of Termination and paid in accordance with Employers’ regular payroll practices. In addition, the Employers shall reimburse an amount equal to the Employers’ portion of the health insurance premiums then paid for active
employees for the level of coverage elected by the Executive pursuant to COBRA until the earlier of the expiration of the twelve (12) month period following the Event of Termination or the date on which Executive receives substantially
comparable coverage and benefits under the group health plans of a subsequent employer. In return for the severance payment described in this Agreement paragraph 7(c), Executive shall agree to execute a full release and waiver (substantially similar
to the Release and Waiver attached hereto as Exhibit “A” and made a part of this Agreement) of all known or unknown claims or causes of action Executive has, had, or may have against the Employers, except that such release shall not apply
to (i) any rights of the Executive to indemnification under the Employers’ Certificate of Incorporation or By-Laws or written agreement or to directors’ and officers’ liability insurance coverage of the Employers and its
affiliates, (ii) any rights to the severance pay or benefits under this Agreement, (iii) any rights to vested tax-qualified retirement benefits, and (iv) any rights to continued group health coverage under COBRA or applicable state
law. The severance payments described in clause (i) above shall commence within 60 days following the Executive’s termination of employment provided the Executive has executed the release and the release has become irrevocable before then.
If the 60-day period described in the immediately preceding sentence begins in one calendar year and ends in a later calendar year, the payments shall commence in the later calendar year even if the Executive executes the release and it becomes
irrevocable in the earlier calendar year. If the Executive does not execute the release and the release does not become irrevocable before the 60th day after the Executive’s termination of employment, the Executive shall not receive the
severance payment described in this Agreement paragraph 7(c). 
 (d) Compliance with Protective Covenants.
Notwithstanding anything to the contrary in this Agreement, in the event Executive fails or ceases to fully abide by all of the covenants contained in Agreement paragraph 9, or in the event any court of competent jurisdiction or arbitrator deems any
such covenant(s) to be invalid or unenforceable as the result of a challenge by Executive, then Executive acknowledges and agrees that such circumstances shall constitute a failure of consideration and Executive shall not be entitled to any
compensation pursuant to Agreement paragraphs 7(b) or (c). If Executive has already received any such compensation at the time he violates any such covenant, the Employers shall immediately be entitled to recover all such amounts in full from
Executive. 
 (e) Limits on Payments. Executive and the Employers intend for all payments under this Agreement to be
either outside the scope of Section 409A of the Code or to comply with its requirements as to timing of payments. Accordingly, to the extent applicable, this Agreement shall at all times be operated in accordance with the


  
 9 








 
requirements of Section 409A of the Code, as amended, and the regulations and rulings thereunder, including any applicable transition rules. The Employers shall have authority to take
action, or refrain from taking any action, with respect to the payments and benefits under this Agreement that is reasonably necessary to comply with Section 409A. Any payments that qualify for the “short-term deferral” exception or
another exception under Section 409A of the Code shall be paid under the applicable exception. For purposes of the limitations on nonqualified deferred compensation under Section 409A of the Code, each payment of compensation under this
Agreement shall be treated as a separate payment of compensation for purposes of applying the Section 409A of the Code deferral election rules and the exclusion under Section 409A of the Code for certain short-term deferral amounts.
Notwithstanding anything in this Agreement to the contrary, if any amounts or benefits payable under this Agreement in the event of Executive’s termination of employment constitute “nonqualified deferred compensation” within the
meaning of Code Section 409A, payment of such amounts and benefits shall commence when the Executive incurs a “separation from service” within the meaning of Treasury Regulation 1.409A-1(h), without regard to any of the optional
provisions thereunder, from the Employers and any entity that would be considered a single employer with the Employers under Code Section 414(b) or 414(c) (“Separation from Service”). Such payments or benefits shall be provided in
accordance with the timing provisions of this Agreement by substituting the Agreement’s references to “termination of employment” or “termination” with Separation from Service. In addition, if at the time of Executive’s
Separation from Service the Executive is a “specified employee” within the meaning of Code Section 409A(a)(2)(B)(i), any amount or benefits that the constitutes “nonqualified deferred compensation” within the meaning of Code
Section 409A that becomes payable to Executive on account of the Executive’s Separation from Service will not be paid until after the earlier of (i) first business day of the seventh month following Executive’s Separation from
Service, or (ii) the date of the Executive’s death (the “409A Suspension Period”). Within 14 calendar days after the end of the 409A Suspension Period, the Executive shall be paid a cash lump sum payment equal to any payments
(including interest on any such payments, at an interest rate of not less than the prime interest rate, as published in the Wall Street Journal, over the period such payment is restricted from being paid to the Executive) and benefits that the
Company would otherwise have been required to provide under this Agreement but for the imposition of the 409A Suspension Period delayed because of the preceding sentence. Thereafter, the Executive shall receive any remaining payments and benefits
due under this Agreement in accordance with the terms of this Section (as if there had not been any Suspension Period beforehand). To the extent not otherwise specified in this Agreement, all (A) reimbursements and (B) in-kind benefits
provided under this Agreement shall be made or provided in accordance with the requirements of Section 409A of the Code, including, where applicable, the requirement that (1) any reimbursement is for expenses incurred during the
Executive’s lifetime (or during a shorter period of time specified in this Agreement); (2) the amount of expenses eligible for reimbursement, or in kind benefits provided, during a calendar year may not affect the expenses eligible for
reimbursement, or in kind benefits to be provided, in any other calendar year; (3) the reimbursement of an eligible expense will be made no later than the last day of the calendar year following the year in which the expense is incurred; and
(4) the right to reimbursement or in kind benefits is not subject to liquidation or exchange for another benefit. 

  
 10 








 Notwithstanding any provision of this Agreement to the contrary, if any payments
or benefits received under this Agreement would constitute an “excess parachute payment” within the meaning of Section 280G of the Code, the payments or benefits provided to Executive under this Agreement will be reduced by reducing
the amount of payments or benefits payable to Executive to the extent necessary so that no portion of Executive’s payments or benefits will be subject to the excise tax imposed by Section 4999 of the Code. Notwithstanding the foregoing, a
reduction will be made under the previous sentence only if, by reason of that reduction, Executive’s net after tax benefit exceeds the net after tax benefit he or she would realize if the reduction were not made. If any payments or benefits are
reduced under this Agreement pursuant to this paragraph and Executive is assessed any excise tax under Code Section 4999 as a result of payments or benefits under this Agreement, the Executive shall pay all such assessed excise taxes, and any
income taxes and additional excise taxes resulting solely from the payment of such excise taxes. 
 (f) Voluntary
Termination of Employment. If the Executive terminates his employment without Good Reason, then the Employers shall pay to Executive, or in the event of his subsequent death, to his designated beneficiary or beneficiaries, or to his estate, as
the case may be, any accrued but unpaid Base Salary through the date of termination of Executive’s employment, and any earned but unpaid cash bonuses for any prior period. 

8. Regulatory Suspension. 

(a) If Executive is suspended and/or temporarily prohibited from participating in the conduct of the affairs of the Bank by a
notice served under Sections 8(e)(3) or (g)(1) of the Federal Deposit Insurance Act, 12 U.S.C. § 1818(e)(3) or (g)(1), the obligations of the Employers under this Agreement shall be suspended as of the date of service of such notice, unless
stayed by appropriate proceedings. If the charges in the notice are dismissed, the Employers, subject to any bar or prohibition arising from any applicable law or regulation, shall (i) pay Executive the compensation withheld while its contract
obligations were suspended and (ii) reinstate in whole or in part any of its obligations which were suspended; provided, however, that the Employers’ obligation to pay or reinstate as set forth herein shall not exceed one year of
compensation or other obligations, shall be reduced by the amount of any compensation received by Executive from any source during the period of suspension, and shall be contingent upon faithful compliance by Executive with the Protective Covenants
in Agreement paragraph 9 throughout such period of suspension. Vested rights of Executive shall not otherwise be affected. 

(b) If Executive is removed and/or permanently prohibited from participating in the conduct of the affairs of the Bank by an
order issued under Section 8(e)(4) or (g)(1) of the Federal Deposit Insurance Act, 12 U.S.C. § 1818(e)(4) or (g)(1), all obligations of the Employers under this Agreement shall terminate as of the effective date of the order, but vested
rights of the parties hereto shall not be affected. 

  
 11 








 9. Protective Covenants. Executive shall abide by and be bound by the following Protective
Covenants: 
 (a) Confidential Information and Trade Secrets. During Executive’s employment, the parties
acknowledge that the Employers shall disclose, or have already disclosed, to Executive for use in Executive’s employment, and that Executive will be provided access to and otherwise make use of, acquire, create, or add to certain valuable,
unique, proprietary, and secret information of the Employers (whether tangible or intangible and whether or not electronically kept or stored), including financial statements, drawings, designs, manuals, business plans, processes, procedures,
formulas, inventions, pricing policies, customer and prospect lists and contacts, contracts, sources and identity of vendors and contractors, financial information of customers of the Employers, and other proprietary documents, materials, or
information indigenous to the Employers, relating to their businesses and activities, or the manner in which the Employers do business, which is valuable to the Employers in conducting their business because the information is kept confidential and
is not generally known to the Employers’ competitors or to the general public (“Confidential Information”). Confidential Information does not include information generally known or easily obtained from public sources or public
records, unless Executive causes the Confidential Information to become generally known or easily obtained from public sources or public records. 

To the extent that the Confidential Information rises to the level of a trade secret under applicable law, then Executive
shall, during Executive’s employment and for so long as the Confidential Information remains a trade secret under applicable law (or for the maximum period of time otherwise allowed by applicable law) (i) protect and maintain the
confidentiality of such trade secrets and (ii) refrain from disclosing, copying, or using any such trade secrets, without the Employers’ prior written consent, except as necessary in Executive’s performance of Executive’s duties
while employed with the Employers. 
 To the extent that the Confidential Information defined above does not rise to the
level of a trade secret under applicable law, Executive shall, during Executive’s employment and for a period of two years following any voluntary or involuntary termination of employment (whether by the Employers or Executive),
(i) protect and maintain the confidentiality of the Confidential Information and (ii) refrain from disclosing, copying, or using any Confidential Information without the Employers’ prior written consent, except as necessary in
Executive’s performance of Executive’s duties while employed with the Employers. 
 (b) Return of Property of
the Employers. Upon any voluntary or involuntary termination of Executive’s employment (or at any time upon request of the Employers), Executive agrees to immediately return to the Employers all property of the Employers (including, without
limitation, all documents, electronic files, records, computer disks or

other tangible or intangible things that may or may not relate to or otherwise comprise Confidential Information or trade secrets, as defined by applicable law) that Executive created, used,
possessed or maintained while working for the Employers from whatever source and whenever created, including all reproductions or excerpts thereof. This provision does not apply to purely personal documents of Executive, but it does apply to
business calendars, Rolodexes, customer lists, contact sheets, computer programs, disks and their contents and like information that may contain some personal matters of Executive. Executive acknowledges that title to all such property is vested in
the Employers. 
 (c) Non-Diversion of Business Opportunity. During Executive’s employment with the Employers and
consistent with Executive’s duties and fiduciary obligations to the Employers, Executive shall (i) disclose to the Employers any business opportunity that comes to Executive’s attention during Executive’s employment with the
Employers and that relates to the business of the Employers or otherwise arises as a result of Executive’s employment with the Employers and (ii) not take advantage of or otherwise divert any such opportunity for Executive’s own
benefit or that of any other person or entity without prior written consent of the Employers. 
 (d) Non-Solicitation of
Customers. During Executive’s employment and for a period of twelve (12) months following any employment termination, Executive agrees not to, directly or indirectly, contact, solicit, divert, appropriate, or call upon, the customers
or clients of the Employers with whom Executive has had material contact during the last year of Executive’s employment with the Employers, including prospects of the Employers with whom Executive had such contact during said last year of
Executive’s employment (i) to solicit such customers or clients or prospective customers or clients for a Competitive Business as herein defined (including, without limitation, any Competitive Business started by Executive) or (ii) to
otherwise encourage any such customer or client to discontinue, reduce, or adversely alter the amount of its business with the Employers. Executive acknowledges that, due to Executive’s relationship with the Employers, Executive will develop,
or has developed, special contacts and relationships with the Employers’ clients and prospects, and that it would be unfair and harmful to the Employers if Executive took advantage of these relationships. 

A “Competitive Business”, as defined in this Agreement, is an enterprise that is in the business of offering
banking products and/or services, which services and/or products are similar or substantially identical to those offered by the Employers during Executive’s employment with the Employers. 

(e) Non-Piracy of Employees. During Executive’s employment and for a period of twelve (12) months following
any termination, Executive covenants and agrees that Executive shall not, directly or indirectly: (i) solicit, recruit, or hire (or attempt to solicit, recruit, or hire) or otherwise assist anyone in soliciting, recruiting, or hiring, any
employee or independent contractor (which shall not include non-exclusive outside vendors) of the Employers who performed work for the Employers within the last six (6) months of Executive’s employment with the Employers or who was
otherwise engaged or employed with the Employers at the time of said termination of employment of Executive 

  
 13 








 
or (ii) otherwise encourage, solicit, or support any such employees or independent contractors to leave their employment or engagement with the Employers, in either case until such employee
or contractor has been terminated or separated from the Employers for at least twelve (12) months. 
 (f)
Non-Compete. During Executive’s employment and for a period of twelve (12) months following any employment termination, Executive agrees not to, directly or indirectly, compete with the Employers, as an officer, director, member,
principal, partner, shareholder (other than a shareholder in a company that is publicly traded and so long as such ownership is less than five percent), owner, manager, supervisor, administrator, employee, consultant, or independent contractor, by
working in the Territory (as defined herein) for or as a “Competitive Business” (as defined above) in the Territory (as defined herein), in a capacity identical or substantially similar to the capacity in which Executive served at the
Employers. The “Territory” shall be defined as any other state in which the Employers actively solicit business or are engaged in doing business. Executive acknowledges that the Employers conduct their business within the Territory, that
Executive will perform services for and on behalf of the Employers within the Territory, and that this paragraph 9(f) (and the Territory) is a reasonable limitation on Executive’s ability to compete with the Employers. 

(g) Acknowledgment. It is understood and agreed by Executive that the parties have attempted to limit his right to
compete only to the extent necessary to protect the Employers from unfair competition and that the terms and provisions of this paragraph 9 are not intended to restrict Executive in the exercise of his skills or the use of knowledge or information
that does not rise to the level of a trade secret under applicable law or Confidential Information of the Employers (to which trade secrets and Confidential Information Executive has had and/or will have access and has made and/or will make use of
during employment with the Employers). 
 It is acknowledged that the purpose of these covenants and promises is (and that
they are necessary) to protect the Employers’ legitimate business interests, to protect the Employers’ investment in the overall development of its business and the good will of its customers, and to protect and retain (and to prevent
Executive from unfairly and to the detriment of the Employers utilizing or taking advantage of) such business trade secrets and Confidential Information of the Employers and those substantial contacts and relationships (including those with
customers and employees of the Employers) which Executive established due to his employment with the Employers. 
 This
Agreement is not intended to preclude Executive’s opportunity to engage in or otherwise pursue occupations in any unrelated or non-competitive field of endeavor, or to engage in or otherwise pursue directly competitive endeavors so long as they
meet the requirements of this Agreement. Executive represents that his experience and abilities are such that existence or enforcement of these covenants and promises will not prevent Executive from earning or pursuing an adequate livelihood and
will not cause an undue burden to Executive or his family. 

  
 14 








 Executive acknowledges that these covenants and promises (and their respective
time, geographic, and/or activity limitations) are reasonable and that said limitations are no greater than necessary to protect said legitimate business interests in light of Executive’s position with the Employers and the Employers’
business, and Executive agrees to strictly abide by the terms hereof. 
 10. Source of Payments. All payments provided in Agreement
paragraphs 4, 6, and 7 shall be paid in cash from the general funds of the Employers, or their successors in interest, as provided herein; and no special or separate fund shall be established by the Employers, and no other segregation of assets
shall be made to assure payment. Executive shall have no right, title, or interest in or to any investments which the Employers may make to meet its payment obligations. 

11. Injunctive Relief/Arbitration. The Employers or Executive shall have the right to apply to any court of competent jurisdiction for
injunctive relief with respect to the enforcement of the covenants and agreements set forth in Agreement paragraph 9. This remedy shall be in addition to, and not in limitation of, any other rights or remedies to which the Employers or Executive are
or may be entitled at law or in equity respecting this Agreement. All other disputes or claims for relief arising from or related to this Agreement, Executive’s employment with the Employers, or the termination of Executive’s employment
with the Employers, or as to arbitrability shall be brought and resolved in binding arbitration before the American Arbitration Association. The arbitration shall be conducted under the AAA National Rules for the Resolution of Employment Disputes.
The Employers and Executive agree that the arbitration will be conducted in Atlanta, Georgia. Judgment upon any award rendered by the arbitrator may be entered only in the Superior Court of Fulton County, Georgia, or in the U.S. District Court for
the Northern District of Georgia (Atlanta Division). 
 12. Attorneys’ Fees. In the event any party hereto is required to engage
in legal action, whether before a court of competent jurisdiction or before the American Arbitration Association, against any other party hereto, either as plaintiff or defendant, in order to enforce or defend any of its or his rights under this
Agreement, and such action results in a final judgment in favor of one or more parties, then the party or parties against whom said final judgment is obtained shall reimburse the prevailing party or parties for all legal fees and expenses incurred
by the prevailing party or parties in asserting or defending its or his rights hereunder. Furthermore, if following a Change of Control Executive must bring a claim to enforce Executive’s rights, and such claim results in payments to Executive,
then whether or not reduced to a final judgment, Executive shall be reimbursed for reasonable legal fees incurred. 
 13. No Duty to
Mitigate. In no event shall the Executive be obligated to seek other employment or take any other action by way of mitigation of the amounts payable to the Executive under any provisions of this Agreement and such amounts shall not be reduced
regardless of whether the Executive obtains other employment. 
 14. Federal Income Tax Withholding. The Employers may withhold from
any benefits payable under this Agreement all federal, state, city, or other taxes as shall be required pursuant to any law or governmental regulation or ruling. 

  
 15 








 15. Effect of Prior Agreements. This Agreement constitutes the entire agreement between
the parties concerning the subject matter of this Agreement. No oral statements or prior written material not specifically incorporated in this Agreement shall be of any force and effect, and no changes in or additions to this Agreement shall be
recognized, unless incorporated in this Agreement by written amendment, such amendment to become effective on the date stipulated in it. Executive acknowledges and represents that, in executing this Agreement, he did not rely, and has not relied, on
any communications, promises, statements, inducements, or representation(s), oral or written, by the Employers or any of its officers, directors, attorneys, agents, or representatives, except as expressly contained in this Agreement. This Agreement
supersedes any prior employment agreement and any contemporaneous oral agreement or understanding by or between the Employers and Executive. 

16. General Provisions. 

(a) Nonassignability. Neither this Agreement nor any right or interest hereunder shall be assignable by Executive, his
beneficiaries or legal representatives, without the prior written consent of the Employers; provided, however, that nothing in this Agreement paragraph 16(a) shall preclude (i) Executive from designating a beneficiary to receive any benefits
payable hereunder upon his death, or (ii) the executors, administrators, or other legal representatives of Executive or his estate from assigning any rights hereunder to the person or persons entitled thereto. The Employers may assign this
Agreement without the consent of Executive. 
 (b) No Attachment. Except as required by law, no right to receive
payments under this Agreement shall be subject to anticipation, commutation, alienation, sale, assignment, encumbrance, charge, pledge, or hypothecation, or to execution, attachment, levy, and any attempt, voluntary or involuntary, to effect any
such action shall be null, void, and of no effect. 
 (c) Binding Agreement. This Agreement shall be binding upon, and
inure to the benefit of, the Employers and Executive and their respective heirs, successors, assigns, and legal representatives. 

(d) No Bar. Executive acknowledges and agrees that the existence of any claim or cause of action against the Employers
shall not constitute a defense to the enforcement by the Employers of Executive’s covenants, obligations, or undertakings in this Agreement. 

(e) No Conflicting Obligations. Executive hereby acknowledges and represents that his execution of this Agreement and
performance of employment-related obligations and duties for the Employers will not cause any breach, default, or violation of any other employment, nondisclosure, confidentiality, non-competition, or other agreement to which Executive may be a
party or otherwise bound. 
 Moreover, Executive hereby agrees that he will not use in the performance of such
employment-related obligations and duties for the Employers or otherwise disclose to the Employers any trade secrets or confidential information of any person or entity 

  
 16

Agreement shall be deemed to have been waived, nor shall there be any estoppel against the enforcement of any provision of this Agreement, except by written instrument of the party charged with such waiver or estoppel. No such written waiver shall
be deemed a continuing waiver unless specifically stated therein, and each waiver shall operate only as to the specific term or condition waived and shall not constitute a waiver of such term or condition for the future or as to any act other than
that specifically waived. 
 18. Severability. If for any reason any provision of this Agreement is held invalid, the parties agree
that the court or arbitrator shall modify the provision(s) (or subpart(s) thereof) to make the provision(s) (or subpart(s) thereof) and this Agreement valid and enforceable. Any invalid provision shall not affect any other provision of this
Agreement not held invalid, and each such other provision shall to the full extent consistent with law continue in full force and effect. If any provision of this Agreement shall be held invalid in part, such invalidity shall in no way affect the
rest of such provision not held so invalid, and the rest of such provision, together with all other provisions of this Agreement, shall to the full extent consistent with law continue in full force and effect.
