written notice to the Executive, without prejudice to any other remedy to which the Employer may be entitled either at law, in equity or under this Agreement. Unless otherwise agreed in writing between the Executive and the Employer, the Executive
shall immediately cease performing and discharging the duties and responsibilities of her positions and remove herself and her personal belongings from the Employer’s premises. All rights and obligations accruing to the Executive under this
Agreement shall cease at such termination, except that such termination shall not prejudice the Executive’s rights regarding employment benefits which shall have accrued prior to such termination, including the right to receive the Severance
Benefits, and any other remedy which the Executive may have at law, in equity or under this Agreement, which remedy accrued prior to such termination. For the avoidance of doubt, if the Company terminates the Executive, but the Executive remains an
employee of the Bank, termination by the Company shall not be deemed a termination without cause for purposes of Section 6.2(a) or constitute a termination of this Agreement. 

(e)    Voluntary Termination by Executive. The Executive may terminate her employment and this
Agreement at any time and for any reason or no reason, upon sixty (60) days prior written notice to the Employer. Unless otherwise agreed in writing between the Executive and the Employer, the Executive shall immediately cease performing and
discharging the duties and responsibilities of her positions and remove herself and her personal belongings from the Employer’s premises. All rights and obligations accruing to the Executive under this Agreement shall cease at such termination,
except that such termination shall not prejudice the Executive’s rights regarding employment benefits which shall have accrued prior to such termination and any other remedy which the Executive may have at law, in equity or under this
Agreement, which remedy accrued prior to such termination. 
 6.2    Certain Benefits upon
Termination. 
 (a)    Termination Without Cause. In the event this Agreement is terminated
based on Section 6.1(d) (termination without Cause), then subject to Section 6.2(c), the Executive shall receive (i) the Accrued Obligations as of the Date of Termination, (ii) an amount
equal to 1.75 times the Executive’s Annual Base Salary, and (iii) COBRA Benefits for a period of twelve (12) months from the Date of Termination, with one hundred percent (100%) of monthly premiums for the insurance coverages payable
by the Employer for a period of twelve (12) months from the Date of Termination. The Executive acknowledges and agrees that Severance Benefits pursuant to this Section 6.2(a) are in lieu of all damages, payments and
liabilities on account of the early termination of this Agreement and are the sole and exclusive remedy for the Executive for a termination specified in Section 6.1(d) of this Agreement. 

  
 8 

 (b)    Termination and Change in Control. In the
event of a Change in Control and at any time during the Change of Control Period (x) the Executive’s employment is terminated by the Employer without Cause, or (y) Executive terminates her employment for a Good Reason, then, subject
to Section 6.2(c), the Executive shall receive (i) the Accrued Obligations as of the Date of Termination, (ii) an amount equal to 2.25 times the Executive’s Annual Base Salary, and (iii) COBRA Benefits
for a period of twenty-four (24) months from the Date of Termination, with one hundred percent (100%) of premiums for the insurance coverages payable by the Employer monthly to the Executive for a period of twenty-four (24) months from the
Date of Termination. The Executive acknowledges and agrees that Severance Benefits pursuant to this Section 6.2(b) are in lieu of all damages, payments and liabilities on account of the events described above for which such
Severance Benefits may be due the Executive under Section 6.2(b) of this Agreement. 

(c)    In order for Executive to receive the Severance Benefits, Executive must (i) deliver an
executed Release to the Company on or before forty-five (45) days following the termination of the Executive’s employment, and not revoke the Release, and (ii) be at all times in compliance with the restrictions of
Section 11 before and after the Date of Termination. Severance Benefits shall be subject to all applicable federal and state deductions and withholding, and any sums owing to the Employer. The consideration for the
execution of the Release is the Severance Benefits, which the Executive would otherwise not be eligible to receive. Notwithstanding anything in this Agreement to the contrary, no Severance Benefits shall be due to the extent such Severance Benefits
are prohibited or limited by an applicable federal or state law, rule or regulation or a federal or state bank regulatory agency acting under applicable federal or state law or regulation. 

(d)    Death. Except as provided in Section 8, if the Executive’s
employment terminates by reason of the Executive’s death, this Agreement shall terminate without further obligations to the Executive’s beneficiary, other than for payment of Accrued Obligations and any incentive compensation for the year
in which the death occurred prorated through the Date of Termination. Accrued Obligations shall be paid to the Executive’s estate or beneficiary, as applicable, in a lump sum in cash within thirty (30) days of the Date of Termination;
provided, however, that payment may be deferred until the Executive’s executor or personal representative has been appointed and qualified pursuant to the laws in effect in the Executive’s jurisdiction of residence at the time of the
Executive’s death. 
 (e)    Disability. If the Executive’s employment terminates by
reason of the Executive’s Disability, this Agreement shall terminate without further obligations to the Executive under this Agreement, other than for payment of Accrued Obligations, and any incentive compensation for the year in which the
termination occurs prorated through the Date of Termination and any benefits under such plans, programs, practices and policies relating to disability benefits, if any, as in effect on the Date of Termination. 

(f)    Cause/Voluntary Termination. If the Executive’s employment terminates for Cause, this
Agreement shall terminate without further obligations to the Executive other than the obligation to pay to the Executive the Accrued Obligations. If the Executive’s employment terminates due to the Executive’s voluntarily termination of
this Agreement, except as provided in clause (y) of Section 6.2(b), this Agreement shall terminate without further obligations to the Executive other than the obligation to pay to the Executive the
Accrued Obligations. 

  
 9 

 (g)    Single Trigger Event. The provisions for
payments contained in this Section 6.2 may be triggered only once during the term of this Agreement, so that, for example, should the Executive be terminated because of a Disability and should there thereafter be a Change
of Control, then the Executive would be entitled to be paid only under Section 6.2(e) and not under Section 6.2(b), as well. 

7.    Form and Payment of Severance Pay. Payments of Severance Pay due under this Agreement shall
be made in substantially equal installments over 12 months in accordance with the Company’s regular payroll practices then in effect, provided, however, that the initial payment shall be made on the first regular payroll date occurring on
or after the sixtieth (60th) day following the Date of Termination (and shall include all payments that would otherwise have been paid prior to such date). For the avoidance of doubt, payments of Accrued Obligations shall be paid on the Date of
Termination. 
 8.    Lump Sum Death Benefit. In the event that an Executive dies after a
Severance Event and prior to receipt of the full amount of such Executive’s Severance Pay, then a lump sum death benefit shall be paid to the estate or beneficiary within ninety (90) days after the date of death of the Executive; provided,
however, that payment may be deferred until the Executive’s executor or personal representative has been appointed and qualified pursuant to the laws in effect in the Executive’s jurisdiction of residence at the time of the
Executive’s death. The lump sum death benefit shall be equal to the aggregate amount of the Severance Pay to which the Executive is entitled, but that has not been paid as of the date of death. Notwithstanding the foregoing, if, as of the date
of death, the Executive has not executed the Release, or if executed, the time for revocation of the Release has not expired, then the payment of the lump sum death benefit shall be subject to the execution by such personal representative or
beneficiary of a release substantially similar in scope to the Release. 
 9.    Excise Tax
Limitation. It is the intention of the Employer and the Executive that no portion of any payment under this Agreement, or payments to or for the benefit of the Executive under any other agreement or plan, be deemed to be an “Excess
Parachute Payment” as defined in Section 280G of the Code, or its successors. The Company shall not be required to make a payment or property transfer to, or for the benefit of, Executive (under this Agreement or otherwise) that would be
nondeductible by the Company by reason of Section 280G of the Code, or that would subject Executive to the exercise tax described in Section 4999 of the Code. In such event, any such payment or property transfer shall be reduced to the
largest amount which may be paid without any portion of such amount being nondeductible by reason of Section 280G of the Code or subject to the excise tax imposed by Section 4999 of the Code. Any such reduction shall be made first to the
payment specified in Section 6.2(b)(ii) of this Agreement. 

10.    Internal Revenue Code Section 409A. This Agreement is intended to comply
with Code Section 409A, including the exceptions for short-term deferrals, separation pay arrangements, reimbursements, and in-kind distributions, and shall be administered, construed and interpreted
accordingly. Each payment under this Agreement or any Company benefit plan is intended to be treated as one of a series of separate payments for purposes of Code Section 409A. 

  
 10 

 
Notwithstanding anything in this Agreement to the contrary, to the extent the Executive is considered a “specified employee” (as defined in Code Section 409A) and would be entitled
to a payment during the six (6)-month period beginning on the Executive’s Date of Termination that is not otherwise exempt from Code Section 409A, the payment shall not be made to the Executive until the earlier of the six (6)-month
anniversary of the Executive’s Date of Termination or the Executive’s death and shall be accumulated and paid on the first (1st) day of the seventh (7th) month following the date of termination. No Severance Benefits that constitute
deferred compensation shall be payable on account of an Executive’s termination of employment unless the Executive’s termination of employment constitutes a “separation from service” within the meaning of Code Section 409A.
Nothing in this Section 10 or otherwise in this Agreement shall be construed as a guarantee of any particular tax effect for Severance Benefits and the Company does not guarantee that any Severance Benefits will satisfy the
provisions of the Code. 
 The Company and the Executive further acknowledge and agree that if, in the judgment of the
Company, with the advice of its independent accounting firm or other tax advisors, amendment of this Agreement is necessary to exempt the benefits from or to comply with Section 409A, the Company and the Executive will negotiate reasonably and
in good faith to amend the terms of this Agreement to the extent necessary so that it exempts the benefits from or to comply with Section 409A (with the most limited possible economic effect on the Company and the Executive). The Executive
acknowledges and agrees that the Company shall have the exclusive authority to determine whether the Executive is a “specified employee” within the meaning of Section 409A(a)(2)(B)(i). 

11.    Restrictive Covenants. 

11.1    Confidential Information. 

(a)    The Executive acknowledges that during the course of employment with the Company and the Bank, the
Executive may produce and have access to confidential and/or proprietary non-public information concerning the Company and its Affiliates. The Executive agrees not to directly or indirectly use, disclose, copy
or make lists of Confidential Information for the benefit of anyone other than the Company and its Affiliates, whether during employment or during five-year period thereafter, except to the extent that such information is or thereafter becomes
lawfully available from public sources, or such disclosure is authorized in writing by the Company, required by law or any competent administrative agency or judicial authority, or otherwise as reasonably necessary or appropriate in connection with
performance by the Executive of duties as an executive of the Company and the Bank. The Executive agrees that, upon receipt of a subpoena or other court order or is otherwise required by law to provide information to a governmental authority or
other person concerning the activities of the Company or the Bank, or her activities in connection with the business of the Company or the Bank, the Executive, to the extent legally permitted, will immediately notify the Company and the Bank of such
subpoena, court order or other requirement and deliver forthwith to the Company a copy thereof and any attachments and non-privileged correspondence related thereto. The Executive shall take reasonable
precautions to protect against the inadvertent disclosure of Confidential Information. The Executive agrees to abide by the Company’s and the Bank’s policies, as in effect from time to time, respecting avoidance of interests conflicting
with those of the Company and the Bank. In this regard, the Executive shall not directly or indirectly render services to any person or entity where the Executive’s service would involve the inevitable use or disclosure of Confidential
Information. 

  
 11 

 (b)    Notwithstanding
Section 11.1, Executive shall not be held criminally or civilly liable under any Federal or State trade secret law for the disclosure of a trade secret that (i) is made (A) in confidence to a Federal, State, or
local government official, either directly or indirectly, or to an attorney; and (B) solely for the purpose of reporting or investigating a suspected violation of law; or (ii) is made in a complaint or other document filed in a lawsuit or
other proceeding, if such filing is made under seal. Accordingly, the Executive has the right to disclose in confidence trade secrets to federal, state, and local government officials, or to an attorney, for the sole purpose of reporting or
investigating a suspected violation of law. The Executive also has the right to disclose trade secrets in a document filed in a lawsuit or other proceeding, but only if the filing is made under seal and protected from public disclosure. Nothing in
this Agreement is intended to conflict with 18 U.S.C. § 1833(b) or create liability for disclosures of trade secrets that are expressly allowed by 18 U.S.C. § 1833(b). Nothing in this Agreement shall be construed to authorize, or limit
liability for, an act that is otherwise prohibited by law, such as the unlawful access of material by unauthorized means. 

(c)    Nothing contained herein shall impede Executive’s ability to report possible federal
securities law violations to the Securities and Exchange Commission and other governmental agencies (i) without the Company’s or Bank’s prior approval, and (ii) without having to forfeit or forego any resulting whistleblower
awards. 
 11.2    Documents and Property. 

(a)    All records, files, documents and other materials or copies thereof relating to the business of
the Company and its Affiliates, which the Executive shall prepare, receive, or use, shall be and remain the sole property of the Company and its Affiliates, other than in connection with performance by the Executive of duties as an executive of the
Company and the Bank, shall not be removed from the premises of the Company or its Affiliates without the Company’s prior written consent, and shall be promptly returned to the Company and the its Affiliates upon the Executive’s
termination of employment together with all copies (including copies or recordings in electronic form), abstracts, notes or reproductions of any kind made from or about the records, files, documents or other materials. 

(b)    The Executive’s access to and permission to use the Company’s and its Affiliates
computer systems, networks and equipment, and all of the Company its Affiliates information contained therein, is restricted to legitimate business purposes on behalf of the Company. Any other access to or use of such systems, network, equipment and
information is without authorization and is prohibited. The restrictions contained herein extend to any personal computers or other electronic devices of the Executive that are used for business purposes relating to the Company or its Affiliates.
The Executive shall not transfer any Company or its Affiliates information to any personal computer or other electronic device that is not otherwise used for any business purpose relating to the Company or its Affiliates. Upon the termination of the
Executive’s employment with the Company and Bank for any reason, the Executive’s authorization to access and permission to use the Company’s or its Affiliates computer systems, networks and equipment, and any Company or its Affiliates
information contained therein, shall cease. 

  
 12 

11.3    Non-Solicitation. The Executive agrees that during
the Restrictive Period the Executive will not, except with the express prior written consent of the Company, directly or indirectly, do any of the following: 

(a)    The Executive will not, directly or indirectly, for herself, or any Financial Institution
(i) induce or attempt to induce any officer of the Company or its Affiliates to leave the employ of the Company or its Affiliates; (ii) in any way interfere with the relationship between the Company or its Affiliates and any officer of the
Company, or its Affiliates; or (iii) induce or attempt to induce any customer, supplier, licensee, or business relation of the Company or its Affiliates to cease doing business with the Company or its Affiliates or in any way interfere with the
relationship between the Company or its Affiliates and their respective customers, suppliers, licensees or business relations. 

(b)    The Executive will not, directly or indirectly, for herself, or any Financial Institution, solicit
the business (where such business solicited is similar in nature to any financial services offered by the Company or its Affiliates as of the Date of Termination) of any person or entity known to the Executive to be a customer of the Company or its
Affiliates, where the Executive, or any person reporting to the Executive, had an ongoing business relationship or had made Substantial Business Efforts with respect to such customer during the Executive’s employment with the Company and the
Bank. 
 11.4    Remedies for Breach of Covenants. The Executive acknowledges and expressly
agrees that the covenants contained in this Section 11 are reasonable with respect to their duration and scope. The Executive further acknowledges that the restrictions contained in this Section 11
are reasonable and necessary for the protection of the legitimate business interests of the Company and its Affiliates, that they create no undue hardships, that any violation of these restrictions would cause substantial injury to the Company and
its Affiliates and such interests, and that such restrictions were a material inducement to the Company and Bank to enter into this Agreement. In the event of any violation or threatened violation of these restrictions, the Company and its
Affiliates, in addition to and not in limitation of, any other rights, remedies or damages available to the Company under this Agreement or otherwise at law or in equity, shall be entitled to preliminary and permanent injunctive relief to prevent or
restrain any such violation by the Executive and any and all persons directly or indirectly acting for or with her, as the case may be. 

12.    Clawback Policy. All Severance Benefits shall be subject to potential cancellation,
recoupment, rescission, payback or other similar action in accordance with the terms of any applicable Company or Bank clawback policy, as it may be amended from time to time (the “Policy”), or any applicable law. An
Executive’s receipt of Severance Benefits shall be deemed to constitute the Executive’s acknowledgment of and consent to the Company’s application, implementation and enforcement of (a) the Policy or any similar policy
established by the Company that may apply to the Executive and (b) any provision of applicable law relating to cancellation, rescission, payback or recoupment of compensation, as well as the Executive’s express agreement that the Company
and the Bank may take such actions as are necessary to effectuate the Policy, any similar policy or applicable law without further consideration or action. 

  
 13 

 13.    Successors. This Agreement will inure to
the benefit of and be binding upon the Bank and the Company and any of their respective successors and assigns. In view of the personal nature of the services to be performed under this Agreement by the Executive, the Executive will not have the
right to assign or transfer any of her rights, obligations or benefits under this Agreement. The Bank and the Company will require any successor (whether direct or indirect, by purchase, merger, consolidation or otherwise) to all or substantially
all of the business and/or assets of the Bank or the Company to assume expressly and agree to perform this Agreement in the same manner and to the same extent that the Bank and the Company would be required to perform it if no such succession had
taken place. As used in this Agreement, “Bank” or “the Company” shall mean the Bank or the Company, as applicable, as hereinbefore defined and any successor to the Company’s or Bank’s business and/or assets as aforesaid
which assumes and agrees to perform this Agreement by operation of law, or otherwise. 

14.    Miscellaneous. 

14.1    Notice. For the purpose of this Agreement, notices and all other communications provided
for in this Agreement shall be in writing and shall be deemed to have been duly given when personally delivered or three (3) days after the date of mailing by United States mail, certified or registered, return receipt requested, postage
prepaid, addressed to the respective addresses set forth below, or to such other addresses as either party may have furnished to the other in writing in accordance herewith, except that notice of a change of address shall be effective only upon

convenience and shall not affect, or be used in connection with, the interpretation of this Agreement. 

  
 14 

 14.4    Severability. The provisions of this
Agreement shall be deemed severable and the invalidity or unenforceability of any provision shall not affect the validity or enforceability of the other provisions hereof.

14.6    Mediation. Prior to engaging in any legal or equitable litigation or other dispute
resolution process, regarding any of the terms and conditions of this Agreement between the parties, or concerning the subject matter of the Agreement between the parties, each party specifically agrees to engage in good faith, in a mediation
process at the expense of the Company, complying with the procedures provided for under California Evidence Code Sections 1115 through and including 1125, as then currently in effect. The parties further and specifically agree to use their best
efforts to reach a mutually agreeable resolution of the matter. The parties understand and specifically agree that should any party to this Agreement refuse to participate in mediation for any reason, the other party will be entitled to seek a court
order to enforce this provision in any court of appropriate jurisdiction requiring the dissenting party to attend, participate, and to make a good faith effort in the mediation process to reach a mutually agreeable resolution of the matter. 

14.7    Arbitration. To the extent not resolved through mediation as provided in
Section 14.6, all claims, disputes and other matters in question arising out of or relating to this Agreement, any termination of the Executive’s employment, the enforcement or interpretation of this Agreement, or
because of an alleged breach, default, or misrepresentation in connection with any of the provisions of this Agreement, including (without limitation) any state or federal statutory claims, shall be resolved by binding arbitration in
Los Angeles County, California, before a sole arbitrator (the “Arbitrator”) mutually selected by the parties from Judicial Arbitration and Mediation Services (“JAMS”) in accordance with the rules
and procedures of JAMS then in effect. If JAMS is no longer able to supply the arbitrator, such arbitrator shall be mutually selected from the American Arbitration Association (“AAA”). The obligation of the parties to
arbitrate pursuant to this Section shall be specifically enforced in accordance with, and shall be conducted consistently with the provisions of Title 9 of Part 3 of the California Code of Civil Procedure as the exclusive remedy of such dispute;
provided, however, that provisional injunctive relief may, but need not, be sought in a court of law while arbitration proceedings are pending, and any provisional injunctive relief granted by such court shall remain effective until the matter is
finally determined by the Arbitrator. Final resolution of any dispute through arbitration may include any remedy or relief that the Arbitrator deems just and equitable, including any and all remedies provided by applicable state or federal statutes.
At the conclusion of the arbitration, the Arbitrator shall issue a written decision that sets forth the essential findings and conclusions upon which the Arbitrator’s award or decision is based. Any award or relief granted by the Arbitrator
hereunder shall be final and binding on the parties hereto and may be enforced by any court of competent jurisdiction. 

14.8    Attorneys Fees. In the event of litigation, arbitration or any other action or proceeding
between the parties to interpret or enforce this Agreement, or any part thereof or relating to this Agreement, the prevailing party shall be entitled to recover its costs related to such 

  
 15 

 
action or proceeding and its reasonable fees of attorneys, accountants and expert witnesses incurred by such party in connection with any such action or proceedings. The prevailing party shall be
deemed to be the party which obtains substantially the relief sought by final resolution, compromise or settlement, or as may otherwise be determined by order of a court of competent jurisdiction in the event of litigation, an award or decision of
an arbitrator in the event of arbitration. 
 14.9    Entire Agreement. This Agreement supersedes
any and all agreements, either oral or in writing, between the parties with respect to the employment of the Executive by the Employer and contains all of the covenants and agreements between the parties with respect to the employment of the
Executive by the Employer. Each party to this Agreement acknowledges that no other representations, inducements, promises, or agreements, oral or otherwise, have been made by any party, or anyone acting on behalf of any party, which are not set
forth herein, and that no other agreement, statement, or promise not contained in this Agreement shall be valid or binding on either party. 

14.10    Waiver. The failure of a party to insist on strict compliance with any of the terms,
provisions, covenants, or conditions of this Agreement by another party shall not be deemed a waiver of any term, provision, covenant, or condition, individually or in the aggregate, unless such waiver is in writing, nor shall any waiver or
relinquishment of any right or power at any one time or times be deemed a waiver or relinquishment of that right or power for all or any other times. 

14.11    Severability. If any provision in this Agreement is held by a court of competent
jurisdiction or arbitrator to be invalid, void, or unenforceable, the remaining provisions shall nevertheless continue in full force and effect without being impaired or invalidated in any way. Any provision of this Agreement held invalid or
unenforceable only in part or degree will remain in full force and effect to the extent not held invalid or unenforceable. 

14.12    Interpretation. This Agreement shall be construed without regard to the party responsible
for the preparation of the Agreement and shall be deemed to have been prepared jointly by the parties. Any ambiguity or uncertainty existing in this Agreement shall not be interpreted against any party, but according to the application of other
rules of contract interpretation, if an ambiguity or uncertainty exists. 
 14.13    Governing Law
and Venue. The laws of the State of California, other than those laws denominated choice of law rules, shall govern the validity, construction and effect of this Agreement. Any action which in any way involves the rights, duties and obligations
of the parties hereunder and is not resolved by binding arbitration shall be brought in the courts of the State of California and venue for any action or proceeding shall be in Los Angeles County or in the United States District Court for the
Southern District of California, and the parties hereby submit to the personal jurisdiction of said courts. 

14.14    Effect of Termination on Certain Provisions. Upon the termination of this Agreement, the
obligations of the Bank, the Company and the Executive hereunder shall cease except to the extent of the Bank’s or the Company’s obligation to make payments, if any, to or for the benefit of the Executive following termination, and
provided that this Section 14 and Sections 4, 11 and 12 shall remain in full force and effect.

 APPENDIX A 

GENERAL RELEASE 

This General Release (“Agreement”) is made by and between OP Bancorp, (including each of the Releasees referenced
below unless otherwise noted) (the “Company”) and Min Kim (“Employee”) in complete, final, and binding settlement of all claims and potential claims, if any, with respect to their employment relationship. The Company and Employee
may collectively be referred to herein as the “Parties.” 

ONE:      Agreement 

This Agreement is based upon the following: 

A.      Employee and Company entered into an Employment Agreement dated November 1, 2017
(“Employment Agreement”). 
 B.      Employee’s last day of employment with the
Company is ________________ (the “Termination Date”). The Parties agree that Employee has no authority to act on behalf of the Company after the Termination Date. 

TWO:      Consideration 

A.      Severance Pay. Employee shall be paid the Severance Pay as defined in the
Employment Agreement, and pursuant to its terms, starting on the first payroll period after the date of the expiration of any and all applicable revocation periods specified in Paragraph FIVE below (provided that Employee
has not exercised any applicable revocation right specified in Paragraph FIVE). The Severance Pay is in the nature of severance pay and not for any work performed for the Company, and therefore shall not result in the
accrual or payment of holiday pay, vacation pay, accrual of any kind of similar benefit, or any other additional benefits. 

B.      COBRA. The Company will pay Employee’s health insurance premium for coverage
to continue through __________________, in accordance with the federal Consolidated Omnibus Budget Reconciliation Act. 

C.      No Further Compensation. The severance payment provided under this
Section TWO shall be referred to as “Severance Payment.” Employee acknowledges and agrees that, except for the Severance Payment, Employee is not entitled to earn or receive any further compensation, payments or
benefits from the Company (including, without limitation, vacation pay, sick pay, floating holiday pay, or any other Company benefits), whether it be for the period of Employee’s employment prior to the Termination Date or otherwise. Employee
further acknowledges and agrees that but for this Agreement, Employee would not be entitled to the Severance Payment. 

  
 APPENDIX A 

-1 

 THREE:     Complete Release 

A.      General Release. As a material inducement to the Company to enter into this
Agreement and to provide the Severance Payment, Employee hereby irrevocably and unconditionally releases, waives and discharges the Company and each and all of the Company’s owners, stockholders, predecessors, successors, assigns, agents,
directors, officers, employees, former employees, representatives, attorneys, accountants, benefit plans, insurers, parent companies, divisions, subsidiaries, affiliates (and owners, stockholders, predecessors, successors, assigns, agents,
directors, officers, employees, representatives, attorneys, accountants, benefit plans and insurers of such parent companies, divisions, subsidiaries and affiliates) and all persons acting by, through, or under or in concert with any of them
(collectively “Releasees”) from any and all individual, class, and/or representative claims, causes of action, demands, complaints and liabilities (including but not limited to attorney’s fees) of any kind whatsoever, whether now
known or unknown, suspected or claimed, which Employee has or may claim to have against any Releasee relating to or arising out of any matter or thing which occurred on or prior to the date of execution of this Agreement, including, without
limitation, any and all individual, class, and/or representative claims arising out of or relating to Employee’s employment with the Company and/or Employee’s employment separation. The released, waived, and discharged claims also include,
but are not limited to individual, class and/or representative claims of any kind for unfair competition, wrongful discharge, constructive discharge, defamation, invasion of privacy, infliction of emotional distress, misrepresentation or fraudulent
inducement, breach of any express or implied contract, claims arising under any Company handbook, manual, policy, or practice, any other claims for severance pay, attorney’s fees and costs, expenses, bonuses, back pay, future wage loss, and

damages, premiums, penalties, and interest, whether such claims are known or unknown, under any theory of law, including state law and federal law, claims for benefits under any employee benefit plan or program, claims for a breach of an implied
covenant of good faith and fair dealing, claims for interference with contract, negligence, or claims under any other federal, state, municipal, or local insurance, human rights, civil rights, wage-hour, pension, or labor laws, rules or regulations,
public policy, contract or tort laws, or any claim of retaliation under such laws, or any claim arising under common law, or under the constitution or any amendments thereto, or any other claim which could be asserted against the Releasee(s) or
which arise out of the Employee’s employment relationship with the Company or the termination of that employment relationship.

Disabilities Act; the Equal Pay Act; the Employee Retirement Income Security Act (ERISA), as amended; the Age Discrimination in Employment Act of 1974, as amended; the Family and Medical Leave Act; the Fair Labor Standards Act; the Worker Adjustment

 APPENDIX A 

-2 

 C.      Release of Monetary Recovery for
Claims Brought on Employee’s Behalf. This release covers not only any and all individual, class and/or representative claims Employee ever had or now has against any Releasee, but it also covers any such claim for a monetary recovery
asserted on Employee’s behalf by any other person or entity, including, without limitation, any government agency, and Employee waives the right to any such monetary recovery. 

D.      To the extent Employee releases persons or entities not signatory to this Agreement,
Employee acknowledges and agrees that Employee’s general release is made for each of their benefit and use. 

E.      The Company and Employee acknowledge and agree that Employee’s general release does
not cover any claims that cannot lawfully be waived or released by Employee. 
 FOUR:
    Waiver of Known and Unknown Claim, Including A Specific Waiver of California Civil Code Section 1542 

Employee expressly waives all rights afforded by any statute (such as Section 1542 of the Civil Code of the State of
California or any other comparable state statute) which limits the effect of a release with respect to unknown claims. Employee understands the significance of Employee’s release of unknown claims and Employee’s waiver of statutory
protection against a release of unknown claims (such as under Section 1542 of the California Civil Code or under any other comparable state statute). For instance, Employee expressly waives any and all rights and benefits under
Section 1542 of The Civil Code of the State of California, which states as follows: 
  

					
		 	 A GENERAL RELEASE DOES NOT EXTEND TO CLAIMS WHICH THE CREDITOR DOES NOT KNOW OR SUSPECT TO EXIST IN HIS OR HER FAVOR AT
THE TIME OF EXECUTING THE RELEASE, WHICH IF KNOWN BY HIM OR HER MUST HAVE MATERIALLY AFFECTED HIS OR HER SETTLEMENT WITH THE DEBTOR.
	  	

 Employee hereby specifically acknowledges and agrees that Employee’s waiver of known and
unknown claims and of Section 1542 of the Civil Code of the State of California is knowing and voluntary. 

FIVE:     Acknowledgment of Rights and Waiver of Claims Under the Age Discrimination In
Employment Act (“ADEA”) 
 Employee acknowledges and agrees that Employee is knowingly and voluntarily waiving
and releasing any rights Employee may have under the Age Discrimination in Employment Act of 1967 (“ADEA”) and pursuant to the Older Workers Benefit Protection Act. Employee also acknowledges that the consideration given for the waiver and
release in this Agreement is in addition to anything of value to which Employee already is entitled, and that, but for this Agreement, Employee would not be entitled to the consideration set forth in Section TWO of this
Agreement. Employee further acknowledges that Employee has been advised by this writing that: (a) Employee’s waiver and release does not apply to any claims that arise after Employee’s execution of this Agreement; (b) Employee
should consult with an attorney prior to executing this Agreement; (c) Employee has twenty-one (21) calendar days from Employee’s receipt of the Agreement to consider this Agreement (although
Employee may by Employee’s own choice 

  
 APPENDIX A 

-3 

 
execute this Agreement earlier, but may not execute this agreement before Employee’s last day of work for the Company); (d) changes to the terms of the Agreement, whether material or
immaterial, will not restart this twenty-one (21) day period; (e) Employee has seven (7) calendar days following Employee’s execution of this Agreement to revoke it in writing; and
(f) this Agreement shall not be effective and enforceable unless and until the seven (7) day revocation period has expired without revocation of the Agreement by Employee (“Effective Date”). Employee may revoke this Release
within seven (7) calendar days only by giving the Company formal, written notice of Employee’s revocation of this Release (by Certified Mail and/or email) to Attention: __________________________________________. Such notice must be
received by the Company before the expiration of the seven (7) day revocation period referenced above. 
 SIX:
       Non Admission of Liability 
 Neither the transfer of any consideration,
the doing of any of the acts referred to in this Agreement, nor anything else contained herein shall be taken or construed to be an admission on the part of the Parties, or any of them, of any wrongdoing, claims, liabilities, obligations, damages,
losses or expenses that could have been asserted in any claim, demand, debt, account, cause of action and/or obligation of any kind whatsoever. 

SEVEN:  Non-Disparagement; Survival 

A.      Employee shall not engage in any disparagement or vilification of the Releasees, and
shall refrain from making any false, negative, critical or disparaging statements, implied or expressed, concerning the Releasees, including regarding management style, methods of doing business, the quality of products and services, role in the
community, or treatment of employees. Employee shall do nothing that would damage the Company’s business reputation or goodwill. 

B.      Employee acknowledges and agrees that Sections 4, 11,
12 and 14 of the Employment Agreement survive termination of Employee’s employment and remain in full force and effect. 

EIGHT:   Covenant Not to Sue 

A.      A “covenant not to sue” is a legal term that means Employee promises not to
file a lawsuit in court. It is different from the release of claims and waiver of rights contained above. Besides waiving and releasing the claims covered above, Employee shall never sue the Releasees in any forum for any reason covered by the
Release. Notwithstanding this covenant not to sue, Employee may bring a claim against the Company to enforce this Agreement, to challenge the validity of this Agreement under the ADEA or for any claim that arises after execution of this Agreement.
If Employee sues any of the Releasees in violation of this Agreement, Employee shall be liable to them for their reasonable attorneys’ fees and costs (including the costs of experts, evidence, and counsel) and other litigation costs incurred in
defending against Employee’s suit. In addition, if Employee sues any of the Releasees in violation of this Agreement, the Company can require Employee to return all but a sum of $100 of the Severance Pay, which sum is, by itself, adequate
consideration for the promises and covenants in this Agreement. In that event, the Company shall have no obligation to make any further Severance Payments. 

  
 APPENDIX A 

-4 

 B.      Notwithstanding the foregoing,
Employee is not waiving the right to report possible securities law violations to the Securities and Exchange Commission and other governmental agencies or the right to receive any resulting whistleblower awards. 

C.      If Employee has previously filed any lawsuit against any of the Releasees, Employee
shall immediately take all necessary steps and execute all necessary documents to withdraw or dismiss such lawsuit to the extent Employee’s agreement to withdraw, dismiss, or not file a lawsuit would not be a violation of any applicable law or
regulation. 
 NINE:      Entire Agreement 

The Employment Agreement and this Agreement supersedes any and all prior agreements or understandings between the Employee and
the Company. This Agreement may only be amended or modified by a written document signed by the Employee and the Company. Employee acknowledges and agrees that the Company has made no representations or promises to Employee other than those
expressly set forth in this Agreement. 
 TEN:      Right to Consult an Attorney

 Employee acknowledges and agrees that Employee (i) has been advised and is hereby advised to consult with an
attorney prior to signing this Agreement; and (ii) is signing this Agreement knowingly and voluntarily after having had the opportunity to consult with Employee’s independent legal counsel, with the intent to be legally bound by its terms.

 ELEVEN: Future Cooperation 

In connection with any and all claims, disputes, negotiations, governmental, internal or other investigations, lawsuits, or
administrative proceedings (the “Legal Matters”) involving the Company or any affiliate, or any of their current or former officers, employees or board members (collectively, the “Disputing Parties” and, individually, each a
“Disputing Party”), Employee shall make himself/herself reasonably available, upon reasonable notice from the Company and without the necessity of subpoena, to provide information and documents, provide declarations and statement regarding
a Disputing Party, meet with attorneys and other representatives of a Disputing Party, prepare for and give depositions and testimony, and otherwise cooperate in the investigation, defense, and prosecution of any and all such Legal Matters, as may,
in the good faith and judgment of the Company, be reasonably requested. The Company shall consult with Employee and make reasonable efforts to schedule such assistance so as not to materially disrupt Employee’s business and personal affairs.
The Company shall reimburse all reasonable expenses incurred by Employee in connection with such assistance, including travel, meals, rental car, and hotel expenses, if any; provided such expenses are approved in advance by the Company and are
documented in a manner consistent with expense reporting policies of the Company as may be in effect from time to time. 

TWELVE:Enforcement 

Employee stipulates that breach by Employee of restrictions and requirements under this Agreement will cause irreparable
damage to the Releasees in the case of Employee’s breach and that the Company would not have entered into this Agreement without binding Employee to these restrictions and requirements. In the event of Employee’s breach of this Agreement,
in addition 

  
 APPENDIX A 

-5 

 
to any other remedies the Company may have, and without bond and without prejudice to any other rights and remedies that the Company may have for Employee’s breach of this Agreement, the
Company shall be relieved of any obligation to provide Severance Payment and shall be entitled to an injunction to prevent or restrain any such violation by Employee and all persons directly or indirectly action for or with Employee. Employee
stipulates that the restrictive period for with the Company is entitled to an injunction shall be extended in for a period that equals the time period during which Employee is or has been in violation of the restrictions contained herein. 

THIRTEEN:    Miscellaneous 

A.      In the event that either Party commences mediation, arbitration, or litigation to
enforce or protect such Party’s rights under this Agreement, the prevailing Party in any such action shall be entitled to recover reasonable attorneys’ fees and costs (including the costs of experts, evidence, and counsel) and other costs
relating to such action, in addition to all other entitled relief, including damages and injunctive relief. 

B.      Should any portion of this Agreement be declared or determined by any court or
arbitrator to be illegal, invalid or unenforceable, the illegal, invalid, or unenforceable portion of this Agreement shall be interpreted as narrowly as possible and shall be deemed stricken and severed from this Agreement, and all other parts,
terms, provisions and portions of this Agreement shall remain unaffected and shall be given full force and effect. 

C.      This Agreement may be executed and delivered in two or more counterparts, each of which
when so executed and delivered shall be deemed original, but such counterparts together shall constitute one and the same instrument. 

D.      The language of all parts of this Agreement shall in all cases be construed as a whole,
according to its fair meaning, and not strictly for or against any Party, and shall be construed without any consideration as to which Party drafted it. 

E.      The titles of various sections in this Agreement are intended solely for convenience of
reference, and are not intended and shall not be deemed for any purpose whatsoever to modify, explain or place construction upon any of the provisions of this Agreement and shall not affect the meaning or interpretation of this Agreement.

STATED AND CONTAINED IN THIS AGREEMENT, AND THAT EMPLOYEE IS SIGNING THIS AGREEMENT KNOWINGLY AND VOLUNTARILY, AFTER HAVING HAD THE OPPORTUNITY FOR CONSULTATION WITH INDEPENDENT LEGAL COUNSEL, WITH THE INTENT TO BE LEGALLY BOUND BY ITS TERMS.
