Act of 1985, as amended (“COBRA”), the Company shall pay, during the period the Employee actually continues such coverage, but in any event not to exceed 18 months, the same percentage of the monthly premium costs for COBRA

after-tax basis to such amount (the “Monthly Payments”); and 
 Payments and benefits provided in
this Section 7(d) shall be in lieu of any termination or severance payments or benefits for which the Employee may be eligible under any of the plans, policies or programs of the Company or under the Worker Adjustment

	 	(iv)	During any period of two (2) consecutive years (not including any period prior to the Effective Date) individuals who constitute the Board on the Effective Date (the “Incumbent Board”) cease for
any reason to constitute at least a majority of the Board; provided, however, that any individual becoming a director subsequent to the Effective Date whose election, or nomination for election by the Company’s shareholders, was approved by a
vote of at least a majority of the directors then comprising the Incumbent Board shall be considered as though such individual were a member of the Incumbent Board, but excluding, for this purpose, any such individual whose initial assumption of
office occurs as a result of an actual or threatened election contest with respect to the election or removal of directors or other actual or threatened solicitation of proxies or consents by or on behalf of a Person other than the Board; or

  

	 	(v)	 Consummation of (A) a reorganization, merger, statutory share exchange or consolidation or similar
transaction involving (x) the Company or (y) any of its Subsidiaries, but in the case of this clause (y) only if equity securities of the Company are issued or issuable in connection with the transaction (each of the events referred
to in this clause (A) being hereinafter referred to as a “Business Reorganization”), or (B) a sale or other disposition of all or substantially all of the assets of the Company, or the acquisition of assets or equity of another
entity by the Company or any of its Subsidiaries (each an “Asset Sale”), in each case, unless, following such Business Reorganization or Asset Sale, (1) all or substantially all of the individuals and entities who were the Beneficial
Owners, respectively, of the Outstanding Company Stock and Outstanding Company Voting Securities immediately prior to such Business Reorganization or Asset Sale beneficially own, directly or indirectly, more than fifty percent (50%) of the
value of the then outstanding equity securities and the combined voting power of the then outstanding voting securities entitled to vote generally in the election of members of the board of directors (or comparable governing body of an entity that
does not have such a board), as the case may be, of the entity resulting from such Business Reorganization or Asset Sale (including, without limitation, an entity which as a result of such transaction owns the Company or all or substantially all of
the Company’s assets either directly or through one or more subsidiaries) (the “Continuing Entity”) in substantially the same proportions as their ownership, immediately prior to such Business Reorganization or Asset Sale, of the
Outstanding Company Stock and Outstanding Company Voting Securities, as the case may be (excluding any outstanding equity or voting securities of the Continuing Entity that such Beneficial Owners hold immediately following the consummation of the
Business Reorganization or Asset Sale as a result of their ownership, prior to such consummation, of equity or voting securities of any company or other entity involved in or forming part of such Business

	 	
Reorganization or Asset Sale other than the Company), (2) no Person (excluding any employee benefit plan (or related trust) of the Company or any Continuing Entity or any entity controlled
by the Continuing Corporation or any Person that as of the Effective Date owns Beneficial Ownership of a Controlling Interest) beneficially owns, directly or indirectly, fifty percent (50%) or more of the value of the then outstanding equity
securities of the Continuing Entity or the combined voting power of the then outstanding voting securities of the Continuing Entity except to the extent that such ownership existed prior to the Business Reorganization or Asset Sale and (3) at
least a majority of the members of the Board of Directors or other governing body of the Continuing Entity were members of the Incumbent Board at the time of the execution of the initial agreement, or of the action of the Board, providing for such
Business Reorganization or Asset Sale. 

 (e)    CODE SECTION 280G. 

(i)    Anything in this Agreement to the contrary notwithstanding, in the event that it shall be determined that any
payment, distribution, or other action by the Company to or for the benefit of the Employee (whether paid or payable or distributed or distributable pursuant to the terms of the Agreement or otherwise (each a “Payment”)), would
result in an “excess parachute payment” within the meaning of Section 280G(b)(i) of the Code, then the Payments shall be reduced to the “Reduced Amount;” provided, however, that no such reduction shall be made unless
the net after-tax benefit received by the Employee after such reduction would exceed the net after-tax benefit received by the Employee if no such reduction was made The
“Reduced Amount” shall be an amount expressed in present value which maximizes the aggregate present value of Payments without causing any Payment to be an excess parachute payment under Section 280G(b)(i) of the Code. For
purposes of this Section 7(e), present value shall be determined in accordance with Section 280G(d)(4) of the Code. If applicable, Payments shall be reduced in the following order: (A) any cash severance based on a multiple of Base
Salary or Annual Bonus; (B) any other cash amounts payable to the Employee; (C) benefits valued as parachute payments; and (D) acceleration of vesting of any equity awards. If and to the extent necessary to avoid a violation of
Section 409A, no amounts payable under any “nonqualified deferred compensation plan” subject to Section 409A shall be reduced until after all other Payments have been reduced. 

(ii)    All determinations required to be made under this Section 7(e), including the amount of any Reduced Amount
and the Payments that are to be reduced pursuant to Section 7(e)(i) and shall be made by the Company’s accountants serving immediately prior to the date of the applicable Change in Control (the “Accounting Firm”), which
shall provide detailed supporting calculations both to the Company and the Employee within 15 business days of the receipt of notice from the Employee that there has been a Payment, or such earlier time as is requested by the Company. The Accounting
Firm’s decision as to which Payments are to be reduced shall be made in consultation with the Employee and shall be subject to the Employee’s consent, which shall not be unreasonably withheld. 

 (f)    OTHER OBLIGATIONS. Upon any termination of the Employee’s
employment with the Company, the Employee shall promptly resign from any position as an officer, director or fiduciary of any Company-related entity. 

(g)    EXCLUSIVE REMEDY. The amounts payable to the Employee following termination of employment and the Employment
Term hereunder pursuant to Sections 6 and 7 hereof shall be in full and complete satisfaction of the Employee’s rights under this Agreement and any other claims that the Employee may have in respect of the Employee’s
employment with the Company or any of its affiliates, and the Employee acknowledges that such amounts are fair and reasonable, and are the Employee’s sole and exclusive remedy, in lieu of all other remedies at law or in equity, with respect to
the termination of the Employee’s employment hereunder or any breach of this Agreement. 
 8.    RELEASE.
Any and all amounts payable and benefits or additional rights provided pursuant to this Agreement beyond the Accrued Benefits shall only be payable if the Employee delivers to the Company and does not revoke a general release of claims in favor
of the Company in substantially the form attached on Exhibit C hereto. Such release shall be executed and delivered (and no longer subject to revocation, if applicable) within sixty (60) days following termination. 

 9.    RESTRICTIVE COVENANTS. 

(a)    CONFIDENTIALITY. During the course of the Employee’s employment with the Company, the Employee
will have access to Confidential Information. For purposes of this Agreement, “Confidential Information” means all data, information, ideas, concepts, discoveries, trade secrets, inventions (whether or not patentable or reduced to
practice), innovations, improvements, know-how, developments, techniques, methods, processes, treatments, drawings, sketches, specifications, designs, plans, patterns, models, plans and strategies, and all
other confidential or proprietary information or trade secrets in any form or medium (whether merely remembered or embodied in a tangible or intangible form or medium) whether now or hereafter existing, relating to or arising from the past, current
or potential business, activities and/or operations of the Company or any of its affiliates, including, without limitation, any such information relating to or concerning finances, sales, marketing, advertising, transition, promotions, pricing,
personnel, customers, suppliers, vendors, partners and/or competitors. The Employee agrees that the Employee shall not, directly or indirectly, use, make available, sell, disclose or otherwise communicate to any person, other than in the course of
the Employee’s assigned duties and for the benefit of the Company, either during the period of the Employee’s employment or at any time thereafter, any Confidential Information or other confidential or proprietary information received from
third parties subject to a duty on the Company’s and its subsidiaries’ and affiliates’ part to maintain the confidentiality of such information, and to use such information only for certain limited purposes, in each case, which shall
have been obtained by the Employee during the Employee’s employment by the Company (or any predecessor). The foregoing shall not apply to information that: (i) was known to the public prior to its disclosure to the Employee;

employee, consultant, independent contractor or otherwise, and whether or not for compensation) or render services to any person, firm, corporation or other entity, in whatever form, engaged in competition with the Company or any of its subsidiaries
or affiliates in any 

 
material business in which the Company or any of its subsidiaries or affiliates is engaged on the date of termination or in which they have planned (that has been approved by the Board of
Directors), on or prior to such date, to be engaged in on or after such date, in any locale of any country in which the Company conducts business. Notwithstanding the foregoing, nothing herein shall prohibit the Employee from being a passive owner
of not more than one percent (1%) of the equity securities of a publicly traded corporation engaged in a business that is in competition with the Company or any of its subsidiaries or affiliates, so long as the Employee has no active participation
in the business of such corporation. In addition, the provisions of this Section 9(b) shall not be violated by the Employee commencing employment with a subsidiary, division or unit of any entity that engages in a business

employee, representative or agent of the Company or any of its subsidiaries or affiliates to leave such employment or retention or to accept employment with or render services to or with any other person, firm, corporation or other entity
unaffiliated with the Company or knowingly hire or retain any such employee, representative or agent, or take any action to materially assist or aid any other person, firm, corporation or other entity in identifying, hiring or soliciting any such
employee, representative or agent, or (B) interfere, or aid or induce any other person or entity in interfering, with the relationship between the Company or any of its subsidiaries or affiliates and any of their respective vendors, joint

while performing the Employee’s duties with the Company or on the Employee’s own time, shall belong exclusively to the Company (or its designee), whether or not patent or other
applications for intellectual property protection are filed thereon (the “Inventions”). The Employee will keep full and complete written records (the “Records”), in the manner prescribed by the Company, of all
Inventions, and will promptly disclose all Inventions completely and in writing to the Company. The Records shall be the sole and exclusive property of the Company, and the Employee will surrender them upon the termination of the Employment Term, or
upon the Company’s request. The Employee irrevocably conveys, transfers and assigns to the Company the Inventions and all patents or other intellectual property rights that may issue thereon in any and all countries, whether during or
subsequent to the Employment Term, together with the right to file, in the Employee’s name or in the name of the Company (or its designee), applications for patents and equivalent rights (the “Applications”). The Employee will,
at any time during and subsequent to the Employment Term, make such applications, sign such papers, take all rightful oaths, and perform all other acts as may be requested from time to time by the Company to perfect, record, enforce, protect, patent
or register the Company’s rights in the Inventions, all without additional compensation to the Employee from the Company. The Employee will also execute assignments to the Company (or its designee) of the Applications, and give the Company and
its attorneys all reasonable assistance (including the giving of testimony) to obtain the Inventions for the Company’s benefit, all without additional compensation to the Employee from the Company, but entirely at the Company’s expense.

 (ii)    In addition, the Inventions will be deemed Work for Hire, as such term is defined under the copyright laws of
the United States, on behalf of the Company and the Employee agrees that the Company will be the sole owner of the Inventions, and all underlying rights therein, in all media now known or hereinafter devised, throughout the universe and in
perpetuity without any further obligations to the Employee. If the Inventions, or any portion thereof, are deemed not to be Work for Hire, or the rights in such Inventions do not otherwise automatically vest in the Company, the Employee hereby
irrevocably conveys, transfers and assigns to the Company, all rights, in all media now known or hereinafter devised, throughout the universe and in perpetuity, in and to the Inventions, including, without limitation, all of the Employee’s
right, title and interest in the copyrights (and all renewals, revivals and extensions thereof) to the Inventions, including, without limitation, all rights of any kind or any nature now or hereafter recognized, including, without limitation, the
unrestricted right to make modifications, adaptations and revisions to the Inventions, to exploit and allow others to exploit the Inventions and all rights to sue at law or in equity for any infringement, or other unauthorized use or conduct in
derogation of the Inventions, known or unknown, prior to the date hereof, including, without limitation, the right to receive all proceeds and damages therefrom. In addition, the Employee hereby waives any
so-called “moral rights” with respect to the Inventions. To the extent that the Employee has any rights in the results and proceeds of the Employee’s service to the Company that cannot be
assigned in the manner described herein, the Employee agrees to unconditionally waive the enforcement of such rights. The Employee hereby waives any and all currently existing and future monetary rights in and to the Inventions and all patents and
other registrations for intellectual property that may issue thereon, including, without limitation, any rights that would otherwise accrue to the Employee’s benefit by virtue of the Employee being an employee of or other service provider to
the Company. 

 (iii)    The parties to this Agreement have 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 parties also have 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. 

(iv)    18 U.S.C. § 1833(b) provides: “An individual shall not be held criminally or civilly liable under any
Federal or State trade secret law for the disclosure of a trade secret that: (A) is made (i) in confidence to a Federal, State, or local government official, either directly or indirectly, or to an attorney; and (ii) solely for the
purpose of reporting or investigating a suspected violation of law; or (B) is made in a complaint or other document filed in a lawsuit or other proceeding, if such filing is made under seal.” 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). Accordingly, the parties to this Agreement have 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 parties also have 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. 
 (e)    RETURN OF
COMPANY PROPERTY. On the date of the Employee’s termination of employment with the Company for any reason (or at any time prior thereto at the Company’s request), the Employee shall return all property belonging to the Company or its
affiliates (including, but not limited to, any Company-provided laptops, computers, cell phones, wireless electronic mail devices or other equipment, or documents and property belonging to the Company). The Employee may retain the Employee’s
rolodex and similar address books provided that such items only include contact information. 
 (f)    REASONABLENESS
OF COVENANTS. In signing this Agreement, the Employee gives the Company assurance that the Employee has carefully read and considered all of the terms and conditions of this Agreement, including the restraints imposed under this
Section 9 hereof. The Employee agrees that these restraints are necessary for the reasonable and proper protection of the Company and its affiliates and their Confidential Information and that each and every one of the
restraints is reasonable in respect to subject matter, length of time and geographic area, and that these restraints, individually or in the aggregate, will not prevent the Employee from obtaining other suitable employment during the period in which
the Employee is bound by the restraints. The Employee acknowledges that each of these covenants has a unique, very substantial and immeasurable value to the Company and its affiliates and that the Employee has sufficient assets and skills to provide
a livelihood while such covenants remain in force. The Employee further covenants that the Employee will not challenge the reasonableness or enforceability of any of the covenants set forth in this Section 9, and that the
Employee will reimburse the Company and its affiliates for all costs (including reasonable attorneys’ fees) incurred in connection with any action to enforce any of the provisions of this Section 9 if either the
Company and/or its affiliates prevails on any material issue involved in such dispute or if the Employee challenges the reasonableness or enforceability of any of the provisions of this Section 9. It is also agreed that
each of the Company’s affiliates will have the right to enforce all of the Employee’s obligations to that affiliate under this Agreement, including without limitation pursuant to this Section 9. 

 (g)    REFORMATION. If it is determined by a court of competent
jurisdiction in any state that any restriction in this Section 9 is excessive in duration or scope or is unreasonable or unenforceable under applicable law, it is the intention of the parties that such restriction may be
modified or amended by the court to render it enforceable to the maximum extent permitted by the laws of that state. 

(h)    TOLLING. In the event of any violation of the provisions of this Section 9, the
Employee acknowledges and agrees that the post-termination restrictions contained in this Section 9 shall be extended by a period of time equal to the period of such violation, it being the intention of the parties hereto
that the running of the applicable post-termination restriction period shall be tolled during any period of such violation. 

(i)    SURVIVAL OF PROVISIONS. The obligations contained in Sections 9 and 10 hereof shall survive
the termination or expiration of the Employment Term and the Employee’s employment with the Company and shall be fully enforceable thereafter. 

10.    COOPERATION. Upon the receipt of reasonable notice from the Company (including outside counsel), the
Employee agrees that while employed by the Company and thereafter, the Employee will respond and provide information with regard to matters in which the Employee has knowledge as a result of the Employee’s employment with the Company, and will
provide reasonable assistance to the Company, its affiliates and their respective representatives in defense of any claims that may be made against the Company or its affiliates, and will provide reasonable assistance to the Company and its
affiliates in the prosecution of any claims that may be made by the Company or its affiliates, to the extent that such claims may relate to the period of the Employee’s employment with the Company (collectively, the “Claims”).
The Employee agrees to promptly inform the Company if the Employee becomes aware of any lawsuits involving Claims that may be filed or threatened against the Company or its affiliates. The Employee also agrees to promptly inform the Company (to the
extent that the Employee is legally permitted to do so) if the Employee is asked to assist in any investigation of the Company or its affiliates (or their actions) or another party attempts to obtain information or documents from the Employee (other
than in connection with any litigation or other proceeding in which the Employee is a party-in-opposition) with respect to matters the Employee believes in good faith to
relate to any investigation of the Company or its affiliates, in each case, regardless of whether a lawsuit or other proceeding has then been filed against the Company or its affiliates with respect to such investigation, and shall not do so unless
legally required. During the pendency of any litigation or other proceeding involving Claims, the Employee shall not communicate with anyone (other than the Employee’s attorneys and tax and/or financial advisors and except to the extent that
the Employee determines in good faith is necessary in connection with the performance of the Employee’s duties hereunder) with respect to the facts or subject matter of any pending or potential litigation or regulatory or administrative
proceeding involving the Company or any of its affiliates without giving prior written notice to the Company or the Company’s counsel. Upon presentation of appropriate documentation, the Company shall pay or reimburse the Employee for all
reasonable out-of-pocket travel, duplicating or telephonic expenses incurred by the Employee in complying with this Section 10. 

11.    WHISTLEBLOWER PROTECTION. Notwithstanding anything to the contrary contained herein, no provision of
this Agreement shall be interpreted so as to impede 

 
the Employee (or any other individual) from reporting possible violations of federal law or regulation to any governmental agency or entity, including but not limited to the Department of
Justice, the Securities and Exchange Commission, the Congress, and any agency Inspector General, or making other disclosures under the whistleblower provisions of federal law or regulation. The Employee does not need the prior authorization of the
Company to make any such reports or disclosures and the Employee shall not be not required to notify the Company that such reports or disclosures have been made. 

12.    EQUITABLE RELIEF AND OTHER REMEDIES. The Employee acknowledges and agrees that the
Company’s remedies at law for a breach or threatened breach of any of the provisions of Section 9 or Section 10 hereof may be inadequate and, in recognition of this fact, the Employee agrees
that, in the event of such a breach or threatened breach, in addition to any remedies at law, the Company, without posting any bond or other security, shall be entitled to obtain equitable relief in the form of specific performance, a temporary
restraining order, a temporary or permanent injunction or any other equitable remedy which may then be available, without the necessity of showing actual monetary damages. In the event of a violation by the Employee of
Section 9 or Section 10 hereof, any severance being paid to the Employee pursuant to this Agreement or otherwise shall immediately cease, and any severance previously paid to the Employee shall be
immediately repaid to the Company. 
 13.    NO ASSIGNMENTS. This Agreement is personal to each of
the parties hereto. Except as provided in this Section 13 hereof, no party may assign or delegate any rights or obligations hereunder without first obtaining the written consent of the other party hereto. The Company may
assign this Agreement to any successor to all or substantially all of the business and/or assets of the Company, provided that the Company shall require such successor to expressly assume and agree to perform this Agreement in the same manner
and to the same extent that the Company would be required to perform it if no such succession had taken place. As used in this Agreement, “Company” shall mean the Company and any successor to its business and/or assets, which
assumes and agrees to perform the duties and obligations of the Company under this Agreement by operation of law or otherwise. 

14.    NOTICE. For purposes 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: (a) on the date of delivery, if delivered by hand, or (b) on the first business day following the date of deposit, if delivered by guaranteed overnight delivery
service, addressed as follows: 
 If to the Employee:

Research Circle 
 Alachua, Florida 32615 

Attention: Chief Executive Officer 
 or to such
other address as either party may have furnished to the other in writing in accordance herewith, except that notices of change of address shall be effective only upon receipt. 

15.    SECTION HEADINGS; INCONSISTENCY. The section headings used in this Agreement are
included solely for convenience and shall not affect, or be used in connection with, the interpretation of this Agreement. In the event of any inconsistency between the terms of this Agreement and any form, award, plan or policy of the Company, the
terms of this Agreement shall govern and control. 
 16.    SEVERABILITY. The provisions of this
Agreement shall be deemed severable. The invalidity or unenforceability of any provision of this Agreement in any jurisdiction shall not affect the validity, legality or enforceability of the remainder of this Agreement in such jurisdiction or the
validity, legality or enforceability of any provision of this Agreement in any other jurisdiction, it being intended that all rights and obligations of the parties hereunder shall be enforceable to the fullest extent permitted by applicable law.

 17.    COUNTERPARTS. This Agreement may be executed in several counterparts, each of which shall
be deemed to be an original but all of which together will constitute one and the same instrument. 

18.    INDEMNIFICATION. The Company hereby agrees to indemnify the Employee and hold the Employee harmless
to the maximum extent permitted by law against and in respect of any and all actions, suits, proceedings, claims, demands, judgments, costs, expenses (including reasonable attorney’s fees), losses, and damages resulting from the Employee’s
good faith performance of the Employee’s duties and obligations with the Company. This obligation shall survive the termination of the Employee’s employment with the Company. 

19.    LIABILITY INSURANCE. The Company shall cover the Employee under directors’ and officers’
liability insurance both during and, while potential liability exists, after the term of this Agreement in the same amount and to the same extent as the Company covers its other officers and directors. 

20.    GOVERNING LAW; JURY WAIVER. This Agreement, the rights and obligations of the parties hereto,
and any claims or disputes relating thereto, shall be governed by 

 
and construed in accordance with the laws of the State of Florida (without regard to its choice of law provisions). Each of the parties agrees that any dispute between the parties shall be
resolved only in the federal courts of the United States of America or the courts of the State of Illinois in each case located in the city of Gainesville and the county of Alachua, and the appellate courts having jurisdiction of appeals in such
courts. In that context, and without limiting the generality of the foregoing, each of the parties hereto irrevocably and unconditionally waives all right to trial by jury in any proceeding (whether based on contract, tort or otherwise) arising out
of or relating to this Agreement or the Employee’s employment by the Company or any affiliate of the Company, or the Employee’s or the Company’s performance under, or the enforcement of, this Agreement. The parties acknowledge and
agree that in connection with any dispute arising hereunder, unless otherwise provided in this Agreement, each party shall pay all of its own costs and expenses, including, without limitation, its own legal fees and expenses. 

21.    MISCELLANEOUS. No provision of this Agreement may be modified, waived or discharged unless such
waiver, modification or discharge is agreed to in writing and signed by the Employee and such officer or director as may be designated by the Board. No waiver by either party hereto at any time of any breach by the other party hereto of, or
compliance with, any condition or provision of this Agreement to be performed by such other party shall be deemed a waiver of similar or dissimilar provisions or conditions at the same or at any prior or subsequent time. This Agreement together with
all exhibits hereto sets forth the entire agreement of the parties hereto in respect of the subject matter contained herein and supersedes any and all prior agreements or understandings between the Employee and the Company with respect to the
subject matter hereof. No agreements or representations, oral or otherwise, express or implied, with respect to the subject matter hereof have been made by either party which are not expressly set forth in this Agreement. 

22.    REPRESENTATIONS. The Employee represents and warrants to the Company that: (a) the Employee has
the legal right to enter into this Agreement and to perform all of the obligations on the Employee’s part to be performed hereunder in accordance with its terms, and (b) the Employee is not a party to any agreement or understanding,
written or oral, and is not subject to any restriction, which, in either case, could prevent the Employee from entering into this Agreement or performing all of the Employee’s duties and obligations hereunder. 

23.    TAX MATTERS. 

(a)    WITHHOLDING. The Company may withhold from any and all amounts payable under this Agreement or
otherwise such federal, state and local taxes as may be required to be withheld pursuant to any applicable law or regulation. 

(b)    SECTION 409A COMPLIANCE. 

(i)    The intent of the parties is that payments and benefits under this Agreement comply with Internal Revenue Code
Section 409A and the regulations and guidance promulgated thereunder (collectively “Code Section 409A”) and, accordingly, to the maximum extent permitted, this Agreement shall be interpreted to be in
compliance therewith. To the extent that any provision hereof is modified in order to comply with Code Section 409A, such modification shall be made in good faith and shall, to the maximum extent reasonably possible,

 
maintain the original intent and economic benefit to the Employee and the Company of the applicable provision without violating the provisions of Code Section 409A. In no event whatsoever
shall the Company be liable for any additional tax, interest or penalty that may be imposed on the Employee by Code Section 409A or damages for failing to comply with Code Section 409A. 

(ii)    A termination of employment shall not be deemed to have occurred for purposes of any provision of this Agreement
providing for the payment of any amounts or benefits upon or following a termination of employment unless such termination is also a “separation from service” within the meaning of Code Section 409A and, for purposes of any such
provision of this Agreement, references to a “termination,” “termination of employment” or like terms shall mean “separation from service.” Notwithstanding anything to the contrary in this Agreement, if the Employee is
deemed on the date of termination to be a “specified employee” within the meaning of that term under Code Section 409A(a)(2)(B), then with regard to any payment or the provision of any benefit that is considered deferred compensation
under Code Section 409A payable on account of a “separation from service,” such payment or benefit shall not be made or provided until the date which is the earlier of: (A) the expiration of the six (6)-month period measured from
the date of such “separation from service” of the Employee, and (B) the date of the Employee’s death, to the extent required under Code Section 409A. Upon the expiration of the foregoing delay period, all payments and
benefits delayed pursuant to this Section 23(b)(ii) (whether they would have otherwise been payable in a single sum or in installments in the absence of such delay) shall be paid or reimbursed to the Employee in a lump
sum, and any remaining payments and benefits due under this Agreement shall be paid or provided in accordance with the normal payment dates specified for them herein. 

(iii)    To the extent that reimbursements or other in-kind benefits under this
Agreement constitute “nonqualified deferred compensation” for purposes of Code Section 409A: (A) all expenses or other reimbursements hereunder shall be made on or prior to the last day of the taxable year following the taxable
year in which such expenses were incurred by the Employee; (B) any right to reimbursement or in-kind benefits shall not be subject to liquidation or exchange for another benefit; and (C) no such
reimbursement, expenses eligible for reimbursement, or in-kind benefits provided in any taxable year shall in any way affect the expenses eligible for reimbursement, or
in-kind benefits to be provided, in any other taxable year. 
 (iv)    For
purposes of Code Section 409A, the Employee’s right to receive any installment payments pursuant to this Agreement shall be treated as a right to receive a series of separate and distinct payments. Whenever a payment under this Agreement
specifies a payment period with reference to a number of days, the actual date of payment within the specified period shall be within the sole discretion of the Company. 

(v)    Notwithstanding any other provision of this Agreement to the contrary, in no event shall any payment under this
Agreement that constitutes “nonqualified deferred compensation” for purposes of Code Section 409A be subject to offset by any other amount unless otherwise permitted by Code Section 409A. 

 24.    REIMBURSEMENT OF LEGAL EXPENSES. Within 60 days of the
date of this Agreement, the Company will pay to the Employee up to $25,000 to cover his legal expenses in connection with the review and negotiation of this Agreement, so long as he provides sufficiently detailed backup for such expenses.

 EXHIBIT A 

RTI SURGICAL, INC. 

RESTRICTED STOCK AGREEMENT 

FOR 
 JONATHON M. SINGER

 1.    Award of Restricted Stock. RTI SURGICAL, INC., a Delaware corporation (the
“Company”) hereby grants, as of September 18, 2017 (the “Date of Grant”), to Jonathon M. Singer (the “Recipient”), a number of restricted shares of the Company’s common stock (rounded to
the nearest whole number) equal to (x) $500,000 divided by (y) the closing price per share of the Company’s common stock on the Nasdaq Stock Market on the Date of Grant, as set forth on Schedule 1 attached to this Agreement (collectively
the “Restricted Stock”). The Restricted Stock shall be subject to the terms, provisions and restrictions set forth in this Agreement and the RTI Surgical, Inc. 2015 Incentive Compensation Plan, as may be amended from time to time
(the “Plan”), which is incorporated herein for all purposes. As a condition to entering into this Agreement, and as a condition to the issuance of any Shares (or any other securities of the Company), the Recipient agrees to be bound
by all of the terms and conditions herein and in the Plan. Unless otherwise provided herein, terms used herein that are defined in the Plan and not defined herein shall have the meanings attributable thereto in the Plan. 

2.    Vesting of Restricted Stock. 

(a)    General Vesting. The shares of Restricted Stock shall become vested in the following amounts, at the
following times and upon the following conditions, provided that, except as otherwise provided in the Employment Agreement between the Company and the Recipient, dated September 15, 2017, as thereafter amended from time to time (the
“Employment Agreement”), the Continuous Service of the Recipient continues through and on the applicable Vesting Date: 
  

			
	 Number of Shares of Restricted Stock
	  	 Vesting Date

	 0
	  	Prior to the first anniversary of the Grant Date.
		
	 1/3 of the Restricted Stock
	  	First anniversary of the Grant Date.
		
	 1/3 of the Restricted Stock
	  	Second anniversary of the Grant Date.
		
	 1/3 of the Restricted Stock
	  	Third anniversary of the Grant Date.

 Except as otherwise provided in Sections 2(b), 2(c) and 4 hereof or the terms of the Employment Agreement,
there shall be no proportionate or partial vesting of shares of Restricted Stock in or during the months, days or periods prior to each Vesting Date, and all vesting of shares of Restricted Stock shall occur only on the applicable Vesting Date. 

 (b)    Acceleration of Vesting Upon Change in Control. In the
event that a Change in Control of the Company occurs during the Recipient’s Continuous Service, the shares of Restricted Stock subject to this Agreement shall become immediately vested as of the date of the Change in Control. Notwithstanding
the foregoing, if in the event of a Change in Control the successor company assumes or substitutes another award for this Restricted Stock award, then the vesting of the Restricted Stock shall not be accelerated as described in this paragraph (b).
For purposes of this paragraph, the Restricted Stock shall be considered assumed or substituted for if following the Change in Control the award confers the right to receive, for each Share subject to the Restricted Stock award immediately prior to
the Change in Control, on substantially the same vesting and other terms and conditions as were applicable to the Restricted Stock immediately prior to the Change in Control, the consideration (whether stock, cash or other securities or property)
received in the transaction constituting a Change in Control by holders of Shares for each Share held on the effective date of such transaction (and if holders were offered a choice of consideration, the type of consideration chosen by the holders
of a majority of the outstanding shares); provided, however, that if such consideration received in the transaction constituting a Change in Control is not solely common stock of the successor company or its parent or subsidiary, the Committee may,
with the consent of the successor company or its parent or subsidiary, provide that the consideration to be received upon the vesting of the Restricted Stock shall be solely common stock of the successor company or its parent or subsidiary
substantially equal in the fair market value to the per share consideration received by holders of Shares in the transaction constituting a Change in Control. The determination of such substantial equality of value of consideration shall be made by
the Committee in its sole discretion and its determination shall be conclusive and binding. 
 (c)    Acceleration
of Vesting at Company Discretion. Notwithstanding any other term or provision of this Agreement, the Board or the Committee shall be authorized, in its sole discretion, based upon its review and evaluation of the performance of the Recipient
and of the Company, to accelerate the vesting of any shares of Restricted Stock under this Agreement, at such times and upon such terms and conditions as the Board or the Committee shall deem advisable. 

(d)    Definitions. For purposes of this Agreement, the following terms shall have the meanings indicated:

 (i)    “Committee” means the Compensation Committee of the Board of Directors of the Company. 

(ii)    “Non-Vested Shares” means any portion of the Restricted
Stock subject to this Agreement that has not become vested pursuant to this Section 2. 
 (iii)     “Vested
Shares” means any portion of the Restricted Stock subject to this Agreement that is and has become vested pursuant to this Section 2. 

 3.    Delivery of Restricted Stock. 

(a)    Issuance of Stock Certificates and Legends. One or more stock certificates evidencing the
Restricted Stock shall be issued in the name of the Recipient but shall be held and retained by the Records Administrator of the Company until the date (the “Applicable Date”) on which the shares (or a portion thereof) subject to
this Restricted Stock award become Vested Shares pursuant to Section 2 hereof, subject to the provisions of Section 4 hereof. All such stock certificates shall bear the following legends, along with such other legends that the Board or the
Committee shall deem necessary and appropriate or which are otherwise required or indicated pursuant to any applicable stockholders agreement: 

THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO SUBSTANTIAL VESTING AND OTHER RESTRICTIONS AS SET FORTH IN THE RESTRICTED STOCK
AGREEMENT BETWEEN THE ISSUER AND THE ORIGINAL HOLDER OF THE SHARES, A COPY OF WHICH MAY BE OBTAINED AT THE PRINCIPAL OFFICE OF THE ISSUER. SUCH RESTRICTIONS ARE BINDING ON TRANSFEREES OF THESE SHARES, AND INCLUDE VESTING CONDITIONS WHICH MAY RESULT
IN THE COMPLETE FORFEITURE OF THE SHARES. 
 (b)    Stock Powers. The Recipient shall deposit with the
Company stock powers or other instruments of transfer or assignment, duly endorsed in blank with signature(s) guaranteed, corresponding to each certificate representing shares of Restricted Stock until such shares become Vested Shares, on a form
attached hereto as Exhibit B. If the Recipient shall fail to provide the Company with any such stock power or other instrument of transfer or assignment, the Recipient hereby irrevocably appoints the Secretary of the Company as his attorney-in-fact, with full power of appointment and substitution, to execute and deliver any such power or other instrument which may be necessary to effectuate the transfer
of the Restricted Stock (or assignment of distributions thereon) on the books and records of the Company. In addition, the Company may require the spouse of the Recipient, if any, to execute and deliver to the Company the Consent of Spouse in the
form attached hereto as Exhibit C. 
 (c)    Delivery of Stock Certificates. On or after each
Applicable Date, upon written request to the Company by the Recipient, the Company shall promptly cause a new certificate or certificates to be issued for and with respect to all shares that become Vested Shares on that Applicable Date, which
certificate(s) shall be delivered to the Recipient as soon as administratively practicable after the date of receipt by the Company of the Recipient’s written request. The new certificate or certificates shall continue to bear those legends and
endorsements that the Company shall deem necessary or appropriate (including those relating to restrictions on transferability and/or obligations and restrictions under the Securities Laws). 

4.    Forfeiture of Non-Vested Shares. Except as provided in the Employment Agreement, if the Recipient’s Continuous
Service with the Company and the Related Entities is terminated for any reason, including, without limitation, by Recipient without Good Reason before October 2, 2020 (as defined in the Employment Agreement), any Shares of Restricted Stock that are
not 

 
Vested Shares, and that do not become Vested Shares pursuant to Section 2 hereof as a result of such termination, shall be forfeited immediately upon such termination of Continuous Service
and revert back to the Company without any payment to the Recipient. If the Recipient breaches any of the Restrictive Covenants as defined in Section 5 hereof, all Non-Vested Shares (and upon written
demand by the Company, in its sole and absolute discretion, any Vested Shares) shall be forfeited immediately upon such breach and revert or be transferred by the Recipient back to the Company without any payment to the Recipient. 

The Committee shall have the power and authority to enforce on behalf of the Company any rights of the Company under this Agreement in the event of the
Recipient’s forfeiture of Non-Vested Shares pursuant to this Section 4. 

5.    Rights with Respect to Restricted Stock. 

(a)    General. Except as otherwise provided in this Agreement, the Recipient shall have, with respect to all
of the shares of Restricted Stock, whether Vested Shares or Non-Vested Shares, all of the rights of a holder of shares of common stock of the Company, including without limitation (i) the right to vote
such Restricted Stock, (ii) the right to receive dividends, if any, as may be declared on the Restricted Stock from time to time, and (iii) the rights available to all holders of shares of common stock of the Company upon any merger,
consolidation, reorganization, liquidation or dissolution, stock split-up, stock dividend or recapitalization undertaken by the Company; provided, however, that all of such rights shall be subject to the
terms, provisions, conditions and restrictions set forth in this Agreement (including without limitation conditions under which all such rights shall be forfeited). Any Shares issued to the Recipient as a dividend with respect to shares of
Restricted Stock shall have the same status and bear the same legend as the shares of Restricted Stock and shall be held by the Company, if the shares of Restricted Stock that such dividend is attributed to is being so held, unless otherwise
determined by the Committee. In addition, notwithstanding any provision to the contrary herein, any cash dividends declared with respect to shares of Restricted Stock subject to this Agreement shall be held in escrow by the Committee until such time
as the shares of Restricted Stock that such cash dividends are attributed to shall become Vested Shares, and in the event that such shares of Restricted Stock are subsequently forfeited, the cash dividends attributable to such portion shall be
forfeited as well. 
 (b)    Adjustments to Shares. If at any time while this Agreement is in effect (or
Shares granted hereunder shall be or remain unvested while Recipient’s Continuous Service continues and has not yet terminated or ceased for any reason), there shall be any increase or decrease in the number of issued and outstanding Shares of
the Company through the declaration of a stock dividend or through any recapitalization resulting in a stock split-up, combination or exchange of such Shares, then and in that event, the Board or the Committee
shall make any adjustments it deems fair and appropriate, in view of such change, in the number of shares of Restricted Stock then subject to this Agreement. If any such adjustment shall result in a fractional Share, such fraction shall be
disregarded. 
 (c)    No Restrictions on Certain Transactions. Notwithstanding any term or provision of
this Agreement to the contrary, the existence of this Agreement, or of any outstanding Restricted Stock awarded hereunder, shall not affect in any manner the right, power or authority 

 
of the Company to make, authorize or consummate: (i) any or all adjustments, recapitalizations, reorganizations or other changes in the Company’s capital structure or its business;
(ii) any merger, consolidation or similar transaction by or of the Company; (iii) any offer, issue or sale by the Company of any capital stock of the Company, including any equity or debt securities, or preferred or preference stock that
would rank prior to or on parity with the Restricted Stock and/or that would include, have or possess other rights, benefits and/or preferences superior to those that the Restricted Stock includes, has or possesses, or any warrants, options or
rights with respect to any of the foregoing; (iv) the dissolution or liquidation of the Company; (v) any sale, transfer or assignment of all or any part of the stock, assets or business of the Company; or (vi) any other corporate
transaction, act or proceeding (whether of a similar character or otherwise). 
 6.    Transferability.
Unless otherwise determined by the Committee, the shares of Restricted Stock are not transferable unless and until they become Vested Shares in accordance with this Agreement, otherwise than by will or under the applicable laws of descent and
distribution. The terms of this Agreement shall be binding upon the executors, administrators, heirs, successors and assigns of the Recipient. Except as otherwise permitted pursuant to the first sentence of this Section, any attempt to effect a
Transfer of any shares of Restricted Stock prior to the date on which the shares become Vested Shares shall be void ab initio. For purposes of this Agreement, “Transfer” shall mean any sale, transfer, encumbrance,
gift, donation, assignment, pledge, hypothecation, or other disposition, whether similar or dissimilar to those previously enumerated, whether voluntary or involuntary, and including, but not limited to, any disposition by operation of law, by court
order, by judicial process, or by foreclosure, levy or attachment. 
 7.    Tax Matters;
Section 83(b) Election. 
 (a)    Section 83(b) Election. If the
Recipient properly elects, within thirty (30) days of the Date of Grant, to include in gross income for federal income tax purposes an amount equal to the fair market value (as of the Date of Grant) of the Restricted Stock pursuant to
Section 83(b) of the Internal Revenue Code of 1986, as amended (the “Code”), a form of which is attached hereto as Exhibit A, the Recipient shall make arrangements satisfactory to the Company to pay to the Company any
federal, state or local income taxes required to be withheld with respect to the Restricted Stock. If the Recipient shall fail to make such tax payments as are required, the Company shall, to the extent permitted by law, have the right to deduct
from any payment of any kind (including without limitation, the withholding of any Shares that otherwise would be issued to the Recipient under this Agreement) otherwise due to the Recipient any federal, state or local taxes of any kind required by
law to be withheld with respect to the Restricted Stock. 
 (b)    No Section 83(b) Election. If the
Recipient does not properly make the election described in paragraph 7(a) above, the Recipient shall, no later than the date or dates as of which the restrictions referred to in this Agreement hereof shall lapse, pay to the Company, or make
arrangements satisfactory to the Committee for payment of, any federal, state or local taxes of any kind required by law to be withheld with respect to the Restricted Stock (including without limitation the vesting thereof), and the Company shall,
to the extent permitted by law, have the right to deduct from any payment of any kind (including without limitation, the withholding of any Shares that otherwise would be distributed to the Recipient under this Agreement) otherwise due to Recipient
any federal, state, or local taxes of any kind required by law to be withheld with respect to the Restricted Stock. 

 (c)    Recipient’s Responsibilities for Tax
Consequences. Tax consequences on the Recipient (including without limitation federal, state, local and foreign income tax consequences) with respect to the Restricted Stock (including without limitation the grant, vesting
and/or forfeiture thereof) are the sole responsibility of the Recipient. The Recipient shall consult with his or her own personal accountant(s) and/or tax advisor(s) regarding these matters, the making of a Section 83(b) election, and the
Recipient’s filing, withholding and payment (or tax liability) obligations. 
 8.    Clawback. 

(a)    The Company may: (x) cause the cancellation of the Restricted Stock; (y) require reimbursement with
respect to the Restricted Stock; and (z) effect any other right of recoupment of equity or other compensation provided under this Agreement or otherwise in accordance with any Company policies generally applicable to the Company’s officers
and/or directors that currently exist or that may from time to time be adopted or modified in the future by the Company to the extent required to comply with applicable law (each, a “Clawback Policy”), provided that the following
conditions are satisfied: (1) there is an accounting restatement of the Company’s financial statements or results; and (2) the restatement results from a noncompliance by the Company with any requirements under or related to the
federal securities laws that is material, injurious to the Company or was the result of actions with bad intent. In such an event, the claw back will be in an amount of up to the total economic gain from any stock-based grants within the five-year
period preceding the restatement. By accepting the Restricted Stock, the Recipient agrees to be bound to any existing or future Clawback Policy adopted by the Company, or any amendments that may from time to time be made to the Clawback Policy in
the future by the Company, as required to comply with applicable laws or stock exchange requirements, and is further agreeing that all of the Recipient’s equity awards may be unilaterally amended by the Company, without the Recipient’s
consent, to the extent that the Company in its discretion determines to be necessary or appropriate to comply with any Clawback Policy to the extent required to comply with applicable laws or stock exchange requirements. 

(b)    If the Recipient, without the consent of the Company, while employed by or providing services to the Company or
after termination of such employment or service, violates a non-competition, non-solicitation or non-disclosure covenant or
agreement or otherwise violates the Company’s Corporate Governance Guidelines, Code of Conduct and Ethics, Code of Ethics for the Chief Executive Officer and Senior Financial Officer or any other corporate governance materials specified by the
SEC or exchange on which common stock of the Company is listed, then, if such violation is material and injurious to the Company, or was the result of actions with bad intent: (i) any outstanding, vested or unvested, earned or unearned portion
of the Restricted Stock may, at the Committee’s discretion, be canceled and (ii) the Committee, in its discretion, may require the Recipient or other person to whom any payment has been made or shares or other property have been
transferred in connection with the Restricted Stock to forfeit and pay over to the Company, on demand, all or any portion of the gain (whether or not taxable) realized upon the sale of any Restricted Stock. 

9.    Amendment, Modification & Assignment; Non-Transferability. This Agreement may
only be modified or amended in a writing signed by the parties hereto. No promises, assurances, 

 commitments, agreements, undertakings or representations, whether oral, written, electronic or otherwise, and
whether express or implied, with respect to the subject matter hereof, have been made by either party which are not set forth expressly in this Agreement. Unless otherwise consented to in writing by the Company, in its sole discretion, this
Agreement (and Recipient’s rights hereunder) may not be assigned, and the obligations of Recipient hereunder may not be delegated, in whole or in part. The rights and obligations created hereunder shall be binding on the Recipient and his heirs
and legal representatives and on the successors and assigns of the Company. 
 10.    Complete
Agreement. This Agreement (together with those agreements and documents expressly referred to herein, for the purposes referred to herein) embody the complete and entire agreement and understanding between the
parties with respect to the subject matter hereof, and supersede any and all prior promises, assurances, commitments, agreements, undertakings or representations, whether oral, written, electronic or otherwise, and whether express or implied, which
may relate to the subject matter hereof in any way. 
 11.    Miscellaneous. 

(a)    No Right to (Continued) Employment or Service. This Agreement and the grant of Restricted Stock
hereunder shall not confer, or be construed to confer, upon the Recipient any right to employment or service, or continued employment or service, with the Company or any Related Entity. 

(b)    No Limit on Other Compensation Arrangements. Nothing contained in this Agreement shall preclude the
Company or any Related Entity from adopting or continuing in effect other or additional compensation plans, agreements or arrangements, and any such plans, agreements and arrangements may be either generally applicable or applicable only in specific
cases or to specific persons. 
 (c)    Severability. If any term or provision of this Agreement is or
becomes or is deemed to be invalid, illegal or unenforceable in any jurisdiction or under any applicable law, rule or regulation, then such provision shall be construed or deemed amended to conform to applicable law (or if such provision cannot be
so construed or deemed amended without materially altering the purpose or intent of this Agreement and the grant of Restricted Stock hereunder, such provision shall be stricken as to such jurisdiction and the remainder of this Agreement and the
award hereunder shall remain in full force and effect). 
 (d)    No Trust or Fund Created. Neither this
Agreement nor the grant of Restricted Stock hereunder shall create or be construed to create a trust or separate fund of any kind or a fiduciary relationship between the Company or any Related Entity and the Recipient or any other person. To the
extent that the Recipient or any other person acquires a right to receive payments from the Company or any Related Entity pursuant to this Agreement, such right shall be no greater than the right of any unsecured general creditor of the Company.

 (e)    Law Governing. This Agreement shall be governed by and construed and enforced in accordance with
the internal laws of the State of Delaware (without reference to the conflict of laws rules or principles thereof). 

 (f)    Interpretation. The Recipient

either party to designate some other address at any time hereafter in a notice satisfying the requirements of this Section. 

(i)    Non-Waiver of Breach. The waiver by any party hereto of the
other party’s prompt and complete performance, or breach or violation, of any term or provision of this Agreement shall be effected solely in a writing signed by such party, and shall not operate nor be construed as a waiver of any subsequent
breach or violation, and the waiver by any party hereto to exercise any right or remedy which he or it may possess shall not operate nor be construed as the waiver of such right or remedy by such party, or as a bar to the exercise of such right or
remedy by such party, upon the occurrence of any subsequent breach or violation. 
 (j)    Counterparts.
This Agreement may be executed in two or more separate counterparts, each of which shall be an original, and all of which together shall constitute one and the same agreement.

NONQUALIFIED STOCK OPTION AGREEMENT 

FOR 
 JONATHON M. SINGER

 1.    Grant of Option. RTI SURGICAL, INC., a Delaware corporation (the “Company”) hereby
grants, as of September 18, 2017 (“Date of Grant”), to Jonathon M. Singer (the “Optionee”) an option (the “Option”) to purchase up to 306,900 shares of the Company’s common
stock (the “Shares”), at an exercise price per share equal to the closing price of the Company’s common stock on the Nasdaq Stock Market on the Date of Grant, as set forth on Schedule 1 attached to this Agreement (the
“Exercise Price”). The Option shall be subject to the terms and conditions set forth herein. The Option is being granted pursuant to the RTI Surgical, Inc. 2015 Incentive Compensation Plan, as may be amended from time to time (the
“Plan”), which is incorporated herein for all purposes. The Option is a Non-Qualified Stock Option and not an Incentive Stock Option. The Optionee hereby acknowledges receipt of a copy of the
Plan and agrees to be bound by all of the terms and conditions hereof and thereof and all applicable laws and regulations. 

2.    Definitions. Unless otherwise provided herein, terms used herein that are defined in the Plan and not defined herein
shall have the meanings attributed thereto in the Plan. 
 3.    Exercise Schedule. Except as otherwise provided in
Sections 6 or 9 of this Agreement, in the Plan or in the Employment Agreement between the Company and the Optionee, dated September 15, 2017, as thereafter amended from time to time (the “Employment Agreement”), the Option is
exercisable in installments as provided below, which shall be cumulative. To the extent that the Option has become exercisable with respect to a number of Shares as provided below, the Option may thereafter be exercised by the Optionee, in whole or
in part, at any time or from time to time prior to the expiration of the Option as provided herein. The following table indicates each date (the “Vesting Date”) upon which the Optionee shall be entitled to exercise the Option with
respect to the number of Shares granted as indicated beside the date, provided that the Continuous Service of the Optionee continues through and on the applicable Vesting Date: 

 

			
	 Number of Shares
	  	 Vesting Date

	0	  	Any date prior to the first anniversary of the Grant Date.
		
	102,300	  	The first day following any 60 Day Period (as defined below) during the Exercise Period on which the Average Stock Price per share is equal to or greater than $7.00 (to be adjusted for any stock splits during the Exercise
Period).

			
		
	102,300	  	The first day following any 60 Day Period during the Exercise Period on which the Average Stock Price per share is equal to or greater than $8.00 (to be adjusted for any stock splits during the Exercise Period).
		
	102,300	  	The first day following any 60 Day Period during the Exercise Period on which the Average Stock Price per share is equal to or greater than $9.00 (to be adjusted for any stock splits during the Exercise Period).

 By way of example, if the Company’s stock price per share is at $5.00 throughout all of calendar year
2018, but then increases to $9.50 on January 2, 2019 and is at or above that same price for 60 days and such 60th day is March 3, 2019, all 225,000 shares of common stock subject to the
Option shall vest on March 4, 2019. 
 For purposes of this Section 3: (I) “60 Day Period” means any period of 60
consecutive calendar days on which the Company’s common stock trades on the Nasdaq Stock Market and (II) “Average Stock Price” is calculated by averaging the closing price of the Company’s common stock for each trading day that
occurs during the 60 Day Period (for calendar days during the 60 Day Period that are not trading days, the closing price on such days shall be deemed to be the closing price on the most recent previous trading day) (e.g., the closing price on a
Saturday will be deemed to equal the closing price on Friday, the day before). 
 Except as otherwise specifically provided herein or in the
Employment Agreement, there shall be no proportionate or partial vesting in the periods prior to each Vesting Date, and all vesting shall occur only on the appropriate Vesting Date. Upon the termination of the Optionee’s Continuous Service, any
unvested portion of the Option shall terminate and be null and void. 
 4.    Method of Exercise. The vested portion of
this Option shall be exercisable in whole or in part in accordance with the exercise schedule set forth in Section 3 hereof by written notice which shall state the election to exercise the Option, the number of Shares in respect of which the
Option is being exercised, and such other representations and agreements as to the holder’s investment intent with respect to such Shares as may be required by the Company pursuant to the provisions of the Plan. Such written notice shall be
signed by the Optionee and shall be delivered in person or by certified mail to the Secretary of the Company. The written notice shall be accompanied by payment of the Exercise Price. This Option shall be deemed to be exercised after both
(a) receipt by the Company of such written notice accompanied by the Exercise Price and (b) arrangements that are satisfactory to the Compensation Committee of the Board of Directors of the Company (the “Committee”) in its
sole discretion have been made for Optionee’s payment to the Company of the amount, if any, that is necessary to be withheld in accordance with applicable Federal or state withholding requirements. No Shares shall be issued pursuant to the
Option unless and until such issuance and such exercise shall comply with all relevant provisions of applicable law, including the requirements of any stock exchange upon which the Shares then may be traded. 

 5.    Method of Payment. Payment of the Exercise Price shall be by any of the
following, or a combination thereof, at the election of the Optionee: (a) cash; (b) check; or (c) to the extent permitted by the Committee, with Shares owned by the Optionee, or the withholding of Shares that otherwise would be delivered
to the Optionee as a result of the exercise of the Option; or (d) such other consideration or in such other manner as may be determined by the Committee in its absolute discretion. 

6.    Termination of Option. 

(a)    General. Any unexercised portion of the Option shall automatically and without notice terminate and
become null and void at the time of the earliest to occur of the following: 
 (i)    three months after the date on
which the Optionee’s Continuous Service is terminated other than by reason of (A) by the Company or a Related Entity for Cause (as defined in the Employment Agreement ), (B) a Disability of the Optionee as determined by a medical doctor
satisfactory to the Committee, (C) the death of the Optionee, (D) Optionee’s Retirement (as defined below) or (E) by the Optionee without Good Reason before October 2, 2020 (as defined in the Employment Agreement); 

(ii)    immediately upon the termination of the Optionee’s Continuous Service (A) by the Company or a Related
Entity for Cause or (B) by the Optionee without Good Reason before October 2, 2020; 
 (iii)    twelve months
after the date on which the Optionee’s Continuous Service is terminated by the Optionee on account of his or her Retirement (as defined below); 

(iv)    twelve months after the date on which the Optionee’s Continuous Service is terminated by reason of a
Disability as determined by a medical doctor satisfactory to the Committee; 
 (v)    twelve months after the date of
termination of the Optionee’s Continuous Service by reason of the death of the Optionee; 
 (vi)    the tenth (10th) anniversary of the date as of which the Option is granted. 
 For purposes of this Agreement,
“Retirement” shall mean the date on which the Optionee voluntarily terminates his or her Continuous Service with the Company and its Related Entities on or after both (A) attaining age sixty (60) and (B) completing at
least five (5) years of Continuous Service with the Company and its Related Entities. 

(b)    Cancellation. To the extent not previously exercised, (i) the Option shall terminate immediately
in the event of (A) the liquidation or dissolution of the Company, or (B) any reorganization, merger, consolidation or other form of corporate transaction in which the Company does not survive or the Shares are exchanged for or converted
into securities issued by another entity, or an affiliate of such successor or acquiring entity, unless the successor or acquiring entity, or an affiliate thereof, assumes the Option or substitutes an equivalent option or right pursuant to
Section 10(c) of the Plan, and (ii) the Committee in its sole discretion may by written notice (“cancellation notice”) cancel, effective upon the consummation of any transaction

 
that constitutes a Change in Control, the Option (or portion thereof) that remains unexercised on such date. The Committee shall give written notice of any proposed transaction referred to in
this Section 6(b) a reasonable period of time prior to the closing date for such transaction (which notice may be given either before or after approval of such transaction), in order that the Optionee may have a reasonable period of time prior
to the closing date of such transaction within which to exercise the Option if and to the extent that it then is exercisable (including any portion of the Option that may become exercisable upon the closing date of such transaction). The Optionee
may condition his exercise of the Option upon the consummation of a transaction referred to in this Section 6(b). 

7.    Transferability. Unless otherwise determined by the Committee, the Option granted hereby is not transferable otherwise
than by will or under the applicable laws of descent and distribution, and during the lifetime of the Optionee the Option shall be exercisable only by the Optionee, or the Optionee’s guardian or legal representative. In addition, the Option
shall not be assigned, negotiated, pledged or hypothecated in any way (whether by operation of law or otherwise), and the Option shall not be subject to execution, attachment or similar process. Upon any attempt to transfer, assign, negotiate,
pledge or hypothecate the Option, or in the event of any levy upon the Option by reason of any execution, attachment or similar process contrary to the provisions hereof, the Option shall immediately become null and void. The terms of this Option
shall be binding upon the executors, administrators, heirs, successors and assigns of the Optionee.  
 8.    No
Rights of Stockholders. Neither the Optionee nor any personal representative (or beneficiary) shall be, or shall have any of the rights and privileges of, a stockholder of the Company with respect to any Shares purchasable or issuable upon
the exercise of the Option, in whole or in part, prior to the date on which the Shares are issued. 
 9.    Acceleration of
Exercisability of Option. 
 (a)    Acceleration Upon Certain Terminations or Cancellations of
Option. This Option shall become immediately fully exercisable in the event that, prior to the termination of the Option pursuant to Section 6 hereof, (i) the Option is terminated pursuant to Section 6(b)(i) hereof, or
(ii) the Company exercises its discretion to provide a cancellation notice with respect to the Option pursuant to Section 6(b)(ii) hereof. 

(b)    Acceleration Upon Change in Control. This Option shall become immediately fully exercisable in the
event that, prior to the termination of the Option pursuant to Section 6 hereof, and during the Optionee’s Continuous Service, there is a “Change in Control”, as defined in Section 9(b) of the Plan. 

(c)    Exception to Acceleration Upon Change in Control. Notwithstanding the foregoing, if in the event of a
Change in Control the successor company assumes or substitutes for the Option, the vesting of the Option shall not be accelerated as described in Section 9(b). For the purposes of this paragraph, the Option shall be considered assumed or
substituted for if following the Change in Control the Option or substituted option confers the right to purchase, for each Share subject to the Option immediately prior to the Change in Control, on substantially the same vesting and other terms and
conditions as were applicable to the Option immediately prior to the Change in Control, the consideration (whether stock, cash or other securities or 

 
property) received in the transaction constituting a Change in Control by holders of Shares for each Share held on the effective date of such transaction (and if holders were offered a choice of
consideration, the type of consideration chosen by the holders of a majority of the outstanding shares); provided, however, that if such consideration received in the transaction constituting a Change in Control is not solely common stock of the
successor company or its parent or subsidiary, the Committee may, with the consent of the successor company, or its parent or subsidiary, provide that the consideration to be received upon the exercise or vesting of the Option will be solely common
stock of the successor company or its parent or subsidiary substantially equal in Fair Market Value to the per share consideration received by holders of Shares in the transaction constituting a Change in Control. The determination of such
substantial equality of value of consideration shall be made by the Committee in its sole discretion and its determination shall be conclusive and binding. 

10.    Clawback. 

(a)    The Company may: (x) cause the cancellation of the Option, (y) require reimbursement with respect to the
Option, and (z) effect any other right of recoupment of equity or other compensation provided under this Agreement or otherwise in accordance with any Company policies generally applicable to the Company’s officers and/or directors that
currently exist or that may from time to time be adopted or modified in the future by the Company to the extent required to comply with applicable law (each, a “Clawback Policy”), provided that the following conditions are
satisfied: (1) there is an accounting restatement of the Company’s financial statements or results; and (2) the restatement results from a noncompliance by the Company with any requirements under or related to the federal securities
laws that is material, injurious to the Company or was the result of actions with bad intent. In such an event, the claw back will be in an amount of up to the total economic gain from any stock-based grants within the five-year period preceding the
restatement. By accepting the Option, the Optionee agrees to be bound to any existing or future Clawback Policy adopted by the Company, or any amendments that may from time to time be made to the Clawback Policy in the future by the Company, as
required to comply with applicable laws or stock exchange requirements, and is further agreeing that all of the Optionee’s equity awards may be unilaterally amended by the Company, without the Optionee’s consent, to the extent that
the Company in its discretion determines to be necessary or appropriate to comply with any Clawback Policy to the extent required to comply with applicable laws or stock exchange requirements.

 EXHIBIT C 

GENERAL RELEASE 

I, Jonathan M. Singer, in consideration of and subject to the performance by RTI Surgical, Inc. (together with its subsidiaries, the
“Company”), of its obligations under the Employment Agreement dated as of [            ], 2017 (the “Agreement”), which are further described on Schedule A
attached hereto, do hereby release and forever discharge as of the date hereof the Company and its respective affiliates and all present, former and future managers, directors, officers, employees, successors and assigns of the Company and its
affiliates and direct or indirect owners (collectively, the “Released Parties”) to the extent provided below (this “General Release”). The Released Parties are intended to be third-party beneficiaries of this
General Release, and this General Release may be enforced by each of them in accordance with the terms hereof in respect of the rights granted to such Released Parties hereunder. Terms used herein but not otherwise defined shall have the meanings
given to them in the Agreement. 
 My employment or service with the Company and its affiliates terminated as
of                    ,                     , and
I hereby resign from any position as an officer, member of the board of managers or directors (as applicable) or fiduciary of the Company or its affiliates (or reaffirm any such resignation that may have already occurred). I understand that any
payments or benefits paid or granted to me under Section 7 of the Agreement represent, in part, consideration for signing this General Release and are not salary, wages or benefits to which I was already entitled. I understand and agree that I
will not receive certain of the payments and benefits specified in Section 7 of the Agreement unless I execute this General Release and do not revoke this General Release within the time period permitted hereafter. I understand and agree that
such payments and benefits are subject to Sections 9 and 10 of the Agreement, which (as noted below) expressly survive my termination of employment and the execution of this General Release. Such payments and benefits will not be considered
compensation for purposes of any employee benefit plan, program, policy or arrangement maintained or hereafter established by the Company or its affiliates. 

Except as provided in paragraphs 4 and 5 below and except for the provisions of the Agreement which expressly survive the termination of my
employment with the Company, I knowingly and voluntarily (for myself, my heirs, executors, administrators and assigns) release and forever discharge the Company and the other Released Parties from any and all claims, suits, controversies, actions,
causes of action, cross-claims, counter-claims, demands, debts, compensatory damages, liquidated damages, punitive or exemplary damages, other damages, claims for costs and attorneys’ fees, or liabilities
of any nature whatsoever in law and in equity, both past and present (through the date that this General Release becomes effective and enforceable) and whether known or unknown, suspected, or claimed against the Company or any of the Released
Parties which I, my spouse, or any of my heirs, executors, administrators or assigns, may have, which arise out of or are connected with my employment with, or my separation or termination from, the Company (including, but not limited to, any
allegation, claim or violation, arising under: Title VII of the Civil Rights Act of 1964, as amended; the Civil Rights Act of 1991; the Age Discrimination in Employment Act of 1967, as amended (including the Older Workers Benefit Protection Act);
the Equal Pay Act of 1963, as amended; the Americans with Disabilities Act of 1990; the Family and Medical Leave Act of 1993; the 

  
 1 

 
Worker Adjustment Retraining and Notification Act; the Employee Retirement Income Security Act of 1974; any applicable Executive Order Programs; the Fair Labor Standards Act; or their state or
local counterparts; or under any other federal, state or local civil or human rights law, or under any other local, state, or federal law, regulation or ordinance; or under any public policy, contract or tort, or under common law; or arising under
any policies, practices or procedures of the Company; or any claim for wrongful discharge, breach of contract, infliction of emotional distress, defamation; or any claim for costs, fees, or other expenses, including attorneys’ fees incurred in
these matters) (all of the foregoing collectively referred to herein as the “Claims”). 
 I represent that I have made no
assignment or transfer of any right, claim, demand, cause of action, or other matter covered by paragraph 2 above. 
 I agree that this
General Release does not waive or release any rights or claims that I may have under the Age Discrimination in Employment Act of 1967 which arise after the date I execute this General Release. I acknowledge and agree that my separation from
employment with the Company in compliance with the terms of the Agreement shall not serve as the basis for any claim or action (including, without limitation, any claim under the Age Discrimination in Employment Act of 1967). 

I agree that I hereby waive all rights to sue or obtain equitable, remedial or punitive relief from any or all Released Parties of any kind
whatsoever in respect of any Claim, including, without limitation, reinstatement, back pay, front pay, and any form of injunctive relief. Notwithstanding the above, I further acknowledge that I am not waiving and am not being required to waive any
right that cannot be waived under law, including the right to file an administrative charge or participate in an administrative investigation or proceeding; provided, however, that I disclaim and waive any right to share or participate
in any monetary award resulting from the prosecution of such charge or investigation or proceeding. Additionally, I am not waiving: (i) any right to the Accrued Benefits or any severance benefits to which I am entitled under the Agreement;
(ii) any claim relating to directors’ and officers’ liability insurance coverage or any right of indemnification under the Company’s organizational documents or otherwise; or (iii) my rights as an equity or security holder
in the Company or its affiliates. 
 In signing this General Release, I acknowledge and intend that it shall be effective as a bar to each
and every one of the Claims hereinabove mentioned or implied. I expressly consent that this General Release shall be given full force and effect according to each and all of its express terms and provisions, including those relating to unknown and
unsuspected Claims (notwithstanding any state or local statute that expressly limits the effectiveness of a general release of unknown, unsuspected and unanticipated Claims), if any, as well as those relating to any other Claims hereinabove
mentioned or implied. I acknowledge and agree that this waiver is an essential and material term of this General Release and that without such waiver the Company would not have agreed to the terms of the Agreement. I further agree that in the event
I should bring a Claim seeking damages against the Company, or in the event I should seek to recover against the Company in any Claim brought by a governmental agency on my behalf, this General Release shall serve as a complete defense to such
Claims to the maximum extent permitted by law. I further agree that I am not aware of any pending claim of the type described in paragraph 2 above as of the execution of this General Release. 

  
 2 

 I agree that neither this General Release, nor the furnishing of the consideration for this
General Release, shall be deemed or construed at any time to be an admission by the Company, any Released Party or myself of any improper or unlawful conduct. 

I agree that if I violate this General Release by suing the Company or the other Released Parties, I will pay all costs and expenses of
defending against the suit incurred by the Released Parties, including reasonable attorneys’ fees. 
 I agree that this General Release
and the Agreement are confidential and agree not to disclose any information regarding the terms of this General Release or the Agreement, except to my immediate family and any tax, legal or other counsel I have consulted regarding the meaning or
effect hereof or as required by law, and I will instruct each of the foregoing not to disclose the same to anyone. 
 Any non-disclosure provision in this General Release does not prohibit or restrict me (or my attorney) from responding to any inquiry about this General Release or its underlying facts and circumstances by the
Securities and Exchange Commission (SEC), the Financial Industry Regulatory Authority (FINRA), any other self-regulatory organization or any governmental entity. 

I hereby acknowledge that Sections 7 through 14, 18 through 21 and 23 of the Agreement shall survive my execution of this General Release.

 I represent that I am not aware of any claim by me other than the claims that are released by this General Release. I acknowledge that I
may hereafter discover claims or facts in addition to or different than those which I now know or believe to exist with respect to the subject matter of the release set forth in paragraph 2 above and which, if known or suspected at the time of
entering into this General Release, may have materially affected this General Release and my decision to enter into it. 
 Notwithstanding
anything in this General Release to the contrary, this General Release shall not relinquish, diminish, or in any way affect any rights or claims arising out of any breach by the Company or by any Released Party of the Agreement after the date
hereof. 
 Whenever possible, each provision of this General Release shall be interpreted in such manner as to be effective and valid under
applicable law, but if any provision of this General Release is held to be invalid, illegal or unenforceable in any respect under any applicable law or rule in any jurisdiction, such invalidity, illegality or unenforceability shall not affect any
other provision or any other jurisdiction, but this General Release shall be reformed, construed and enforced in such jurisdiction as if such invalid, illegal or unenforceable provision had never been contained herein.

 Exhibit 10.5 

RTI SURGICAL, INC. 

RESTRICTED STOCK AGREEMENT 

FOR 
 JONATHON M. SINGER

 1.    Award of Restricted Stock. RTI SURGICAL, INC., a Delaware corporation (the
“Company”) hereby grants, as of September 18, 2017 (the “Date of Grant”), to Jonathon M. Singer (the “Recipient”), a number of restricted shares of the Company’s common stock (rounded to
the nearest whole number) equal to (x) $500,000 divided by (y) the closing price per share of the Company’s common stock on the Nasdaq Stock Market on the Date of Grant, as set forth on Schedule 1 attached to this Agreement (collectively
the “Restricted Stock”). The Restricted Stock shall be subject to the terms, provisions and restrictions set forth in this Agreement and the RTI Surgical, Inc. 2015 Incentive Compensation Plan, as may be amended from time to time
(the “Plan”), which is incorporated herein for all purposes. As a condition to entering into this Agreement, and as a condition to the issuance of any Shares (or any other securities of the Company), the Recipient agrees to be bound
by all of the terms and conditions herein and in the Plan. Unless otherwise provided herein, terms used herein that are defined in the Plan and not defined herein shall have the meanings attributable thereto in the Plan. 

2.    Vesting of Restricted Stock. 

(a)    General Vesting. The shares of Restricted Stock shall become vested in the following
amounts, at the following times and upon the following conditions, provided that, except as otherwise provided in the Employment Agreement between the Company and the Recipient, dated September 15, 2017, as thereafter amended from time to time
(the “Employment Agreement”), the Continuous Service of the Recipient continues through and on the applicable Vesting Date: 
  

			
	
Number of Shares of Restricted Stock
	  	 Vesting Date

	0	  	Prior to the first anniversary of the Grant Date.
		
	1/3 of the Restricted Stock	  	First anniversary of the Grant Date.
		
	1/3 of the Restricted Stock	  	Second anniversary of the Grant Date.
		
	1/3 of the Restricted Stock	  	Third anniversary of the Grant Date.

 Except as otherwise provided in Sections 2(b), 2(c) and 4 hereof or the terms of the Employment Agreement,
there shall be no proportionate or partial vesting of shares of Restricted Stock in or during the months, days or periods prior to each Vesting Date, and all vesting of shares of Restricted Stock shall occur only on the applicable Vesting Date. 

(b)    Acceleration of Vesting Upon Change in Control. In the event that a Change in Control
of the Company occurs during the Recipient’s Continuous Service, the shares of Restricted Stock subject to this Agreement shall become immediately vested as of the date of the Change in Control. Notwithstanding the foregoing, if in the event of
a Change in Control the successor company assumes or substitutes another award for this Restricted Stock award, then the vesting of the Restricted Stock shall 

 
not be accelerated as described in this paragraph (b). For purposes of this paragraph, the Restricted Stock shall be considered assumed or substituted for if following the Change in Control the
award confers the right to receive, for each Share subject to the Restricted Stock award immediately prior to the Change in Control, on substantially the same vesting and other terms and conditions as were applicable to the Restricted Stock
immediately prior to the Change in Control, the consideration (whether stock, cash or other securities or property) received in the transaction constituting a Change in Control by holders of Shares for each Share held on the effective date of such
transaction (and if holders were offered a choice of consideration, the type of consideration chosen by the holders of a majority of the outstanding shares); provided, however, that if such consideration received in the transaction constituting a
Change in Control is not solely common stock of the successor company or its parent or subsidiary, the Committee may, with the consent of the successor company or its parent or subsidiary, provide that the consideration to be received upon the
vesting of the Restricted Stock shall be solely common stock of the successor company or its parent or subsidiary substantially equal in the fair market value to the per share consideration received by holders of Shares in the transaction
constituting a Change in Control. The determination of such substantial equality of value of consideration shall be made by the Committee in its sole discretion and its determination shall be conclusive and binding. 

(c)    Acceleration of Vesting at Company Discretion. Notwithstanding any other term or
provision of this Agreement, the Board or the Committee shall be authorized, in its sole discretion, based upon its review and evaluation of the performance of the Recipient and of the Company, to accelerate the vesting of any shares of Restricted
Stock under this Agreement, at such times and upon such terms and conditions as the Board or the Committee shall deem advisable. 

(d)    Definitions. For purposes of this Agreement, the following terms shall have the meanings indicated:

 (i)    “Committee” means the Compensation Committee of the Board of Directors of the Company. 

(ii)    “Non-Vested Shares” means any portion of the Restricted
Stock subject to this Agreement that has not become vested pursuant to this Section 2. 
 (iii)    “Vested
Shares” means any portion of the Restricted Stock subject to this Agreement that is and has become vested pursuant to this Section 2. 

3.    Delivery of Restricted Stock.  

(a)    Issuance of Stock Certificates and Legends. One or more stock certificates evidencing
the Restricted Stock shall be issued in the name of the Recipient but shall be held and retained by the Records Administrator of the Company until the date (the “Applicable Date”) on which the shares (or a portion thereof) subject
to this Restricted Stock award become Vested Shares pursuant to Section 2 hereof, subject to the provisions of Section 4 hereof. All such stock certificates shall bear the following legends, along with such other legends that the Board or
the Committee shall deem necessary and appropriate or which are otherwise required or indicated pursuant to any applicable stockholders agreement: 

THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO SUBSTANTIAL VESTING AND OTHER RESTRICTIONS AS SET FORTH IN THE RESTRICTED STOCK
AGREEMENT BETWEEN THE ISSUER AND THE ORIGINAL HOLDER OF THE SHARES, A COPY OF WHICH MAY BE OBTAINED AT THE PRINCIPAL OFFICE OF THE ISSUER. SUCH RESTRICTIONS ARE BINDING ON TRANSFEREES OF THESE SHARES, AND INCLUDE VESTING CONDITIONS WHICH MAY RESULT
IN THE COMPLETE FORFEITURE OF THE SHARES. 

  
 2 

 (b)    Stock Powers. The Recipient shall deposit with the
Company stock powers or other instruments of transfer or assignment, duly endorsed in blank with signature(s) guaranteed, corresponding to each certificate representing shares of Restricted Stock until such shares become Vested Shares, on a form
attached hereto as Exhibit B. If the Recipient shall fail to provide the Company with any such stock power or other instrument of transfer or assignment, the Recipient hereby irrevocably appoints the Secretary of the Company as his attorney-in-fact, with full power of appointment and substitution, to execute and deliver any such power or other instrument which may be necessary to effectuate the transfer
of the Restricted Stock (or assignment of distributions thereon) on the books and records of the Company. In addition, the Company may require the spouse of the Recipient, if any, to execute and deliver to the Company the Consent of Spouse in the
form attached hereto as Exhibit C. 
 (c)    Delivery of Stock Certificates. On or after each
Applicable Date, upon written request to the Company by the Recipient, the Company shall promptly cause a new certificate or certificates to be issued for and with respect to all shares that become Vested Shares on that Applicable Date, which
certificate(s) shall be delivered to the Recipient as soon as administratively practicable after the date of receipt by the Company of the Recipient’s written request. The new certificate or certificates shall continue to bear those legends and
endorsements that the Company shall deem necessary or appropriate (including those relating to restrictions on transferability and/or obligations and restrictions under the Securities Laws). 

4.    Forfeiture of Non-Vested Shares. Except as provided in the Employment
Agreement, if the Recipient’s Continuous Service with the Company and the Related Entities is terminated for any reason, including, without limitation, by Recipient without Good Reason before October 2, 2020 (as defined in the Employment
Agreement), any Shares of Restricted Stock that are not Vested Shares, and that do not become Vested Shares pursuant to Section 2 hereof as a result of such termination, shall be forfeited immediately upon such termination of Continuous Service
and revert back to the Company without any payment to the Recipient. If the Recipient breaches any of the Restrictive Covenants as defined in Section 5 hereof, all Non-Vested Shares (and upon written
demand by the Company, in its sole and absolute discretion, any Vested Shares) shall be forfeited immediately upon such breach and revert or be transferred by the Recipient back to the Company without any payment to the Recipient. 

The Committee shall have the power and authority to enforce on behalf of the Company any rights of the Company under this Agreement in the event of the
Recipient’s forfeiture of Non-Vested Shares pursuant to this Section 4. 

5.    Rights with Respect to Restricted Stock. 

(a)    General. Except as otherwise provided in this Agreement, the Recipient shall have, with respect to all
of the shares of Restricted Stock, whether Vested Shares or Non-Vested Shares, all of the rights of a holder of shares of common stock of the Company, including without limitation (i) the right to vote
such Restricted Stock, (ii) the right to receive dividends, if any, as may be declared on the Restricted Stock from time to time, and (iii) the rights available to all holders of shares of common stock of the Company upon any merger,
consolidation, reorganization, liquidation or dissolution, stock split-up, stock dividend or recapitalization undertaken by the Company; provided, however, that all of such rights shall be subject to the
terms, provisions, conditions and restrictions set forth in this Agreement (including without limitation conditions under which all such rights shall be forfeited). Any Shares issued to the Recipient as a dividend with respect to shares of
Restricted Stock shall have the same status and bear the same legend as the shares of Restricted Stock and shall be held by the Company, if the shares of 

  
 3 

 
Restricted Stock that such dividend is attributed to is being so held, unless otherwise determined by the Committee. In addition, notwithstanding any provision to the contrary herein, any cash
dividends declared with respect to shares of Restricted Stock subject to this Agreement shall be held in escrow by the Committee until such time as the shares of Restricted Stock that such cash dividends are attributed to shall become Vested Shares,
and in the event that such shares of Restricted Stock are subsequently forfeited, the cash dividends attributable to such portion shall be forfeited as well. 

(b)    Adjustments to Shares. If at any time while this Agreement is in effect (or Shares granted hereunder
shall be or remain unvested while Recipient’s Continuous Service continues and has not yet terminated or ceased for any reason), there shall be any increase or decrease in the number of issued and outstanding Shares of the Company through the
declaration of a stock dividend or through any recapitalization resulting in a stock split-up, combination or exchange of such Shares, then and in that event, the Board or the Committee shall make any
adjustments it deems fair and appropriate, in view of such change, in the number of shares of Restricted Stock then subject to this Agreement. If any such adjustment shall result in a fractional Share, such fraction shall be disregarded. 

(c)    No Restrictions on Certain Transactions. Notwithstanding any term or provision of this Agreement to
the contrary, the existence of this Agreement, or of any outstanding Restricted Stock awarded hereunder, shall not affect in any manner the right, power or authority of the Company to make, authorize or consummate: (i) any or all adjustments,
recapitalizations, reorganizations or other changes in the Company’s capital structure or its business; (ii) any merger, consolidation or similar transaction by or of the Company; (iii) any offer, issue or sale by the Company of any
capital stock of the Company, including any equity or debt securities, or preferred or preference stock that would rank prior to or on parity with the Restricted Stock and/or that would include, have or possess other rights, benefits and/or
preferences superior to those that the Restricted Stock includes, has or possesses, or any warrants, options or rights with respect to any of the foregoing; (iv) the dissolution or liquidation of the Company; (v) any sale, transfer or
assignment of all or any part of the stock, assets or business of the Company; or (vi) any other corporate transaction, act or proceeding (whether of a similar character or otherwise). 

6.    Transferability. Unless otherwise determined by the Committee, the shares of Restricted Stock are not transferable
unless and until they become Vested Shares in accordance with this Agreement, otherwise than by will or under the applicable laws of descent and distribution. The terms of this Agreement shall be binding upon the executors, administrators, heirs,
successors and assigns of the Recipient. Except as otherwise permitted pursuant to the first sentence of this Section, any attempt to effect a Transfer of any shares of Restricted Stock prior to the date on which the shares become Vested Shares
shall be void ab initio. For purposes of this Agreement, “Transfer” shall mean any sale, transfer, encumbrance, gift, donation, assignment, pledge, hypothecation, or other disposition, whether similar or dissimilar to
those previously enumerated, whether voluntary or involuntary, and including, but not limited to, any disposition by operation of law, by court order, by judicial process, or by foreclosure, levy or attachment. 

7.    Tax Matters; Section 83(b) Election. 

(a)    Section 83(b) Election. If the Recipient properly elects, within thirty (30) days of the Date of
Grant, to include in gross income for federal income tax purposes an amount equal to the fair market value (as of the Date of Grant) of the Restricted Stock pursuant to Section 83(b) of the Internal Revenue Code of 1986, as amended (the
“Code”), a form of which is attached hereto as Exhibit A, the Recipient shall make arrangements satisfactory to the Company to pay to the Company any federal, state or local income taxes required to be withheld with respect
to the Restricted Stock. If the Recipient shall fail to make such tax payments as are required, the Company shall, to the extent permitted by law, have the right to deduct from any payment of any kind (including without limitation, the withholding
of any Shares that otherwise would be issued to the Recipient under this Agreement) otherwise due to the Recipient any federal, state or local taxes of any kind required by law to be withheld with respect to the Restricted Stock. 

  
 4 

 (b)    No Section 83(b) Election. If the Recipient does
not properly make the election described in paragraph 7(a) above, the Recipient shall, no later than the date or dates as of which the restrictions referred to in this Agreement hereof shall lapse, pay to the Company, or make arrangements
satisfactory to the Committee for payment of, any federal, state or local taxes of any kind required by law to be withheld with respect to the Restricted Stock (including without limitation the vesting thereof), and the Company shall, to the extent
permitted by law, have the right to deduct from any payment of any kind (including without limitation, the withholding of any Shares that otherwise would be distributed to the Recipient under this Agreement) otherwise due to Recipient any federal,
state, or local taxes of any kind required by law to be withheld with respect to the Restricted Stock. 

(c)    Recipient’s Responsibilities for Tax Consequences. Tax consequences on the Recipient (including
without limitation federal, state, local and foreign income tax consequences) with respect to the Restricted Stock (including without limitation the grant, vesting and/or forfeiture thereof) are the sole responsibility of the Recipient. The
Recipient shall consult with his or her own personal accountant(s) and/or tax advisor(s) regarding these matters, the making of a Section 83(b) election, and the Recipient’s filing, withholding and payment (or tax liability) obligations.

 8.    Clawback. 

(a)    The Company may: (x) cause the cancellation of the Restricted Stock; (y) require reimbursement with
respect to the Restricted Stock; and (z) effect any other right of recoupment of equity or other compensation provided under this Agreement or otherwise in accordance with any Company policies generally applicable to the Company’s officers
and/or directors that currently exist or that may from time to time be adopted or modified in the future by the Company to the extent required to comply with applicable law (each, a “Clawback Policy”), provided that the following
conditions are satisfied: (1) there is an accounting restatement of the Company’s financial statements or results; and (2) the restatement results from a noncompliance by the Company with any requirements under or related to the
federal securities laws that is material, injurious to the Company or was the result of actions with bad intent. In such an event, the claw back will be in an amount of up to the total economic gain from any stock-based grants within the five-year
period preceding the restatement. By accepting the Restricted Stock, the Recipient agrees to be bound to any existing or future Clawback Policy adopted by the Company, or any amendments that may from time to time be made to the Clawback Policy in
the future by the Company, as required to comply with applicable laws or stock exchange requirements, and is further agreeing that all of the Recipient’s equity awards may be unilaterally amended by the Company, without the Recipient’s
consent, to the extent that the Company in its discretion determines to be necessary or appropriate to comply with any Clawback Policy to the extent required to comply with applicable laws or stock exchange requirements.
