Dear Dr. Babu:

As part of our review of the terms of our employment agreements with our executives and our intentions to align the terms of such agreements so that they are generally consistent with one another, this letter agreement (the “Agreement”) amends and restates the employment letter agreement, dated April 27, 2012, as amended November 18, 2013, previously entered into between you and us. You are currently employed by BioCryst Pharmaceuticals, Inc., a Delaware corporation (the “Company”), as Chief Discovery Officer, reporting directly to the Chief Research & Development Officer. This Agreement will serve to confirm our agreement with respect to the terms and conditions of your continued employment.

Term of Employment.

(a)

Subject to the terms and conditions of this Agreement, the Company hereby employs Dr. Y.S. Babu (“Employee”) as Chief Discovery Officer. Employee shall maintain employment at the Company’s offices in Birmingham, Alabama. Employee shall devote substantially full-time attention to the business and affairs of the Company and its affiliates. Employee may (i) serve on corporate, civic, charitable or non-profit boards or committees, subject in all cases to the prior written approval in accordance with all applicable policies of the Company and its affiliates as in effect from time to time, and (ii) manage personal and family investments, participate in industry organizations and deliver lectures at educational institutions or events, so long as no such service or activity interferes, individually or in the aggregate, with the performance of Employee’s responsibilities hereunder.

(b)

The term of employment of Employee under this Agreement shall begin on the date first set forth above (the “Effective Date”) and shall continue until Employee is terminated in accordance with Section 4 of this Agreement.

Basic Full-Time Compensation and Benefits.

As basic compensation for services rendered under this Agreement, Employee shall be entitled to receive from the Company a salary equal to no less than Employee’s current base salary (the “Base Salary”), payable in accordance with the Company’s standard payroll practices as in effect from time to time during the term of this Agreement. The Base Salary will be reviewed annually by the Board or a committee thereof and may be raised at the discretion of the Board or such committee.

(b)

Employee shall be eligible to earn a cash bonus, payable as soon as reasonably practicable in the calendar year following each calendar year during the term of this Agreement, based on the Company’s and/or Employee’s achievement of performance related goals proposed by management and approved by the Board or a committee thereof for the Company’s applicable fiscal year (the “Incentive Compensation”). The Incentive Compensation actually earned, if any, shall be determined in the sole discretion of the Board or a committee thereof and shall be based on a target amount equal to forty percent (40%) of the Base Salary earned by Employee during such fiscal year (the “Target Amount”), which shall not be pro-rated for the first fiscal year of the term of this Agreement. The Board or a committee thereof may, in its discretion, approve an Incentive Compensation payment in excess of the Target Amount if the performance goals have been exceeded. Employee must be employed by the Company at the time Incentive Compensation payments are paid in order to receive the Incentive Compensation payment for each fiscal year.

Employee shall be entitled to receive such other benefits and perquisites provided to similarly situated executives of the Company, subject to modification or termination at any time, which benefits may include, without limitation, reasonable paid time off, medical, dental, and vision benefits, life insurance, and participation in profit sharing or retirement plans.

Performance-Based Equity Awards.

During the term of this Agreement, Employee shall be eligible to receive equity-based compensation as determined in the sole discretion of the Board or a committee thereof, which may be subject to the achievement of certain performance targets set by the Board or such committee. All such equity-based awards shall be subject to the terms and conditions set forth in the Company’s Stock Incentive Plan as in effect from time to time and award agreements issued thereunder.

Termination.

(a)

If Employee’s employment is terminated (i) by the Company for Cause, (ii) by Employee other than, following a Change of Control, pursuant to a Constructive Termination, or (iii) Employee’s death or Disability, the Company shall pay Employee (A) any accrued and unpaid Base Salary, payable on the next payroll date; (B) reimbursement for any and all monies advanced or expenses incurred in connection with Employee’s employment for reasonable and necessary expenses incurred by Employee on behalf of the Company for the period ending on the termination date, which amount shall be reimbursed within thirty (30) days of the Company’s receipt of proper documentation from Employee; (C) any compensation that Employee had previously deferred (including any interest earned or credited thereon), in accordance with the terms and conditions of the applicable deferred compensation plans or arrangements then in effect, to the extent vested as of Employee’s termination date, paid pursuant to the terms of such plans or arrangements; and (D) any vested amount or benefit payable under any welfare or retirement benefit plan or program in accordance with the terms thereof (the foregoing items in this Section 4(a), the “Accrued Obligations”).

(c)

The Company’s obligation to provide Severance is conditioned upon Employee returning to the Company all of its property and confidential information that is in Employee’s possession and Employee’s execution and non-revocation of an enforceable release of claims (the “Release”). If Employee chooses not to execute the Release, revokes Employee’s execution of the Release, or fails to comply with the terms of the Release, then the Company shall have no obligation to provide Severance and such Severance amount is subject to recoupment by the Company. The Release shall be provided to Employee no later than seven (7) days following Employee’s separation from service and Employee must execute it within the time period specified in the Release (which shall not be longer than forty-five (45) days from the date of receipt). The Release shall not be effective until any applicable revocation period has expired.

Non-Competition; Proprietary Information and Inventions.

(a)

Proprietary Information and Inventions Agreement; Non-Competition and Non-Solicitation Agreement. As a condition precedent to the employment of Employee by the Company pursuant to the terms of this Agreement, Employee shall execute (i) the Company’s Proprietary Information and Inventions Agreement, attached hereto as Exhibit A, and (ii) the Company’s Non-Competition and Non-Solicitation Agreement, attached hereto as Exhibit B.

(b)

Equitable Remedies. Employee acknowledges and recognizes that a violation of the Proprietary Information and Inventions Agreement or the Non-Competition and Non-Solicitation Agreement by Employee may cause irreparable and substantial damage and harm to the Company or its affiliates, could constitute a failure of consideration, and that money damages will not provide a full remedy for the Company for such violations. Employee agrees that in the event of Employee’s breach of the Proprietary Information and Inventions Agreement or the Non-Competition and Non-Solicitation Agreement, the Company will be entitled, if it so elects, to institute and prosecute proceedings at law or in equity to obtain damages with respect to such breach, to enforce the specific performance of such agreement(s) by Employee, and to enjoin Employee from engaging in any activity in violation hereof.

Miscellaneous.

(a)

Entire Agreement. This Agreement, including the exhibits hereto, constitutes the entire agreement between the parties relating to the employment of Employee by the Company and there are no terms relating to such employment other than those contained in this Agreement and supersedes all other agreements or understandings related to the subject matter contained herein, including without limitation, the employment letter agreement, dated April 27, 2012, as amended November 18, 2013, previously entered into between Employee and the Company. No modification or variation hereof shall be deemed valid unless in writing and signed by the parties hereto. No waiver by either party of any provision or condition of this Agreement shall be deemed a waiver of similar or dissimilar provisions or conditions at any time.

(b)

Assignability. This Agreement may not be assigned without prior written consent of the parties hereto, except that the Company may assign this Agreement to a wholly-owned subsidiary of the Company without prior written consent of Employee. To the extent allowable pursuant to this Agreement, this Agreement shall be binding upon and shall inure to the benefit of each of the parties hereto and their respective executors, administrators, personal representatives, heirs, successors and assigns.

(c)

Notices. Any notice or other communication given or rendered hereunder by any party hereto shall be in writing and delivered personally or sent by registered or certified mail, postage prepaid, at the respective addresses of the parties hereto as set forth below.

(d)

Captions. The section headings contained herein are inserted only as a matter of convenience and reference and in no way define, limit or describe the scope of this Agreement or the intent of any provision hereof.

(e)

Taxes. All amounts to be paid to Employee hereunder are in the nature of compensation for Employee’s employment by the Company, and shall be subject to withholding, income, occupation and payroll taxes and other charges applicable to such compensation.

(f)

Section 409A. The parties intend for the payments and benefits under this Agreement to be exempt from Section 409A of the Internal Revenue Code of 1986, as amended (the “Code”), or, if not so exempt, to be paid or provided in a manner which complies with the requirements of such section, and intend that this Agreement shall be construed and administered in accordance with such intention. In the event the Company determines that a payment or benefit under this Agreement may not be in compliance with Section 409A of the Code, the Company shall reasonably confer with Employee in order to modify or amend this Agreement to comply with Section 409A of the Code and to do so in a manner to best preserve the economic benefit of this Agreement. Notwithstanding anything contained herein to the contrary, (i) in the event (A) any payments described in Section 4 would be “deferred compensation” subject to Section 409A of the Code; and (B) Employee is a “specified employee” (as defined in Code Section 409A(2)(B)(i)), such payments shall, to the extent required by Code Section 409A, be delayed for the minimum period and in the minimum manner necessary to avoid the imposition of the tax required by Section 409A of the Code; (ii) each amount to be paid or benefit to be provided under this Agreement shall be construed as a separately identified payment for purposes of Section 409A of the Code; (iii) any payments that are due within the “short term deferral period” as defined in Section 409A of the Code shall not be treated as deferred compensation unless applicable law requires otherwise; and (iv) amounts reimbursable to Employee under this Agreement shall be paid to Employee on or before the last day of the year following the year in which the expense was incurred and the amount of expenses eligible for reimbursement (and in-kind benefits provided to Employee) during any one (1) year may not affect amounts reimbursable or provided in any subsequent year. Notwithstanding anything in this Agreement to the contrary, in the event any payments hereunder could occur in one of two calendar years as a result of being dependent upon the Release becoming nonrevocable, then, to the extent required to avoid the imposition of taxes or penalties under Section 409A of the Code, such payments shall commence on the first regularly scheduled payroll date of the Company, following the date the Release becomes nonrevocable, that occurs in the second of such two calendar years.

(g)

Golden Parachute Provisions. If it is determined that any payment or benefit provided by the Company to or for the benefit of Employee, whether paid or payable or distributed or distributable pursuant to the terms of this Agreement or otherwise, including, by example and not by way of limitation, acceleration by the Company or otherwise of the date of vesting or payment under any plan, program, arrangement or agreement of the Company would be subject to the excise tax imposed by Internal Revenue Code section 4999 or any interest or penalties with respect to such excise tax (such excise tax together with any such interest and penalties, shall be referred to as the “Excise Tax”), then the Company shall first make a calculation under which such payments or benefits provided to Employee are reduced to the extent necessary so that no portion thereof shall be subject to the Excise Tax (the “4999 Limit”). The Company shall then compare (i) Employee’s Net After-Tax Benefit (as defined below) assuming application of the 4999 Limit with (ii) Employee’s Net After-Tax Benefit without application of the 4999 Limit. Employee shall be entitled to the greater of (i) or (ii). “Net After-Tax Benefit” shall mean the sum of (x) all payments that Employee receives or is entitled to receive that are contingent on a change in the ownership or effective control of the Company or in the ownership of a substantial portion of the assets of the Company within the meaning of Internal Revenue Code section 280G(b)(2), less (y) the amount of federal, state, local, employment, and Excise Tax (if any) imposed with respect to such payments. Any reduction pursuant to this Section 6(g) shall be implemented by determining the Parachute Payment Ratio (as defined below) for each “parachute payment” and then reducing the “parachute payments” in order beginning with the “parachute payment” with the highest Parachute Payment Ratio. For “parachute payments” with the same Parachute Payment Ratio, such “parachute payments” shall be reduced based on the time of payment of such “parachute payments,” with amounts having later payment dates being reduced first. For “parachute payments” with the same Parachute Payment Ratio and the same time of payment, such “parachute payments” shall be reduced on a pro rata basis (but not below zero) prior to reducing “parachute payments” with a lower Parachute Payment Ratio. “Parachute Payment Ratio” shall mean a fraction the numerator of which is the value of the applicable “parachute payment” for purposes of Internal Revenue Code Section 280G and the denominator of which is the actual present value of such payment.

(h)

Governing Law. This Agreement is made and shall be governed by and construed in accordance with the laws of the State of Alabama without respect to its conflicts of law principles.

Exhibit A

(Proprietary Information and Inventions Agreement)

EMPLOYEE’S PROPRIETARY INFORMATION AND INVENTIONS AGREEMENT

I, Y.S. Babu, recognize that BioCryst Pharmaceuticals, Inc., a Delaware corporation (the “Company” and together with its subsidiaries, including existing and future subsidiaries, the “Company Group”), is engaged in a continuous program of research, development, and production respecting its business, present and future, including fields generally related to its business.

I understand that:

As part of my employment by a member of the Company Group, I will faithfully and diligently serve and endeavor to further and safeguard the interests of the Company Group, and I recognize that I am expected to make new contributions and inventions of value to the Company Group;

My employment creates a relationship of confidence and trust between me and the Company Group with respect to any information:

i. applicable to the business of the Company Group; or

ii. applicable to the business of any client or customer of the Company Group,

in each case which may be made known to me by any member of the Company Group or by any client or customer thereof or learned by me during the period of my employment.

The Company Group possesses and will continue to possess information that has been created, discovered or developed by, or assigned, disclosed or otherwise become known to, it (including without limitation information created, discovered, developed, disclosed or made known by me during the period of or arising out of my employment by any member of the Company Group) , which information is not generally known to the public. All of the aforementioned information is hereinafter called “Proprietary Information.” By way of illustration, but not limitation, Proprietary Information includes trade secrets, processes, formulas, data and know-how, improvements, inventions, techniques, marketing plans, financial information, strategies, forecasts, and customer lists.

In consideration of my employment or continued employment, as the case may be, by any member of the Company Group and the compensation received by me from any member of the Company Group from time to time, I hereby agree as follows:

All Proprietary Information shall be the sole property of the Company, and the Company shall be the sole owner of all rights, title and interest in connection therewith. I hereby assign to the Company any and all rights I may have or acquire in such Proprietary Information. At all times, both during my employment by any member of the Company Group and after termination, I will keep in confidence and trust all Proprietary Information, and I will not use or disclose any Proprietary Information or anything relating to it without the prior written consent of the Company, except as may be necessary in the ordinary course of performing my duties as an employee of the Company Group. In the event I am required to disclose Proprietary Information pursuant to applicable law or court order, I shall, whenever legally permissible, promptly disclose such request to the Company, and cooperate with the Company to seek a protective order and to otherwise limit such disclosure from becoming public.

Notwithstanding anything set forth in this Agreement, or any other agreement that I have with the Company or its affiliates to the contrary, I shall not be prohibited from reporting possible violations of federal or state law or regulation to any governmental agency or entity, legislative body, or any self-regulatory organization, or making other disclosures that are protected under the whistleblower provisions of federal or state law or regulation, nor am I required to notify the Company regarding any such reporting, disclosure or cooperation with the government. Pursuant to 18 U.S.C. § 1833(b), I understand that I will not be held criminally or civilly liable under any federal or state trade secret law for the disclosure of a trade secret of the Company or its affiliates that (i) is made (A) in confidence to a federal, state, or local government official, either directly or indirectly, or to my attorney and (B) solely for the purpose of reporting or investigating a suspected violation of law; or (ii) is made in a complaint or other document that is filed under seal in a lawsuit or other proceeding. I understand that if I file a lawsuit for retaliation by any member of the Company Group for reporting a suspected violation of law, I may disclose the trade secret to my attorney and use the trade secret information in the court proceeding if I (x) file any document containing the trade secret under seal, and (y) do not disclose the trade secret, except pursuant to court order. Nothing in this Agreement, or any other agreement that I have with the Company or its affiliates, is intended to conflict with 18 U.S.C. § 1833(b) or create liability for disclosures of trade secrets that are expressly allowed by such section.

I agree that, during the period of my employment by any member of the Company Group, I will not, without the Company’s express prior written consent, engage in any employment or consulting other than for the Company Group. In the event of the termination of my employment by me or by the Company Group for any reason or at any time upon the Company’s request, I will promptly deliver to the Company all documents and data of any nature pertaining to my work with the Company Group and I will not take with me any documents or data containing or pertaining to any Proprietary Information.

A-2

I will promptly and fully disclose to the Company, or any persons designated by it, all improvements, inventions, formulas, processes, techniques, know-how, and data, whether or not patentable, copyrightable, or otherwise protectible as intellectual property, made or conceived or reduced to practice by me, either alone or jointly with others, during the period of my employment by any member of the Company Group which are related to or useful in the business of the Company Group, or result from the performance of my duties as an employee of any member of the Company Group or result from use of assets or premises owned, leased, or contracted for by any member of the Company Group (all said improvements, inventions, formulas, processes, techniques, know-how, and data shall be collectively hereinafter called “Inventions”). I agree to keep complete, accurate, and authentic accounts, notes, data, and records of all Inventions in the manner and form requested by the Company, which accounts, notes, data, and records shall be and remain the sole property of the Company. I agree to surrender the same promptly to the Company upon its request or, in the absence of such a request, upon the termination of my employment by the Company Group.

I agree that all Inventions are and shall be the sole property of the Company, and that the Company shall be the sole owner of all intellectual property and other rights in connection therewith, and by reason of my being employed by any member of the Company Group, to the extent permitted by law, all of the Inventions consisting of copyrightable subject matter is “work made for hire” as defined in the Copyright Act of 1976 (17 U.S.C. § 101). To the extent that any Invention is not a “work made for hire,” I hereby assign to the Company for no additional consideration any and all rights I may have or acquire in or to such Inventions, including the right to xxx, counterclaim, and recover for all past, present, and future infringement, misappropriation, or dilution thereof, and all rights corresponding thereto throughout the world. I further agree as to all such Inventions to assist the Company in every proper way (but at the Company’s expense) to apply for, obtain, maintain and from time to time enforce such intellectual property rights, including patents and extensions and continuations of said patents, on said Inventions in any and all countries, and to that end I will execute all documents for use in applying for, obtaining and maintaining such intellectual property enforcing same, as the Company may desire, together with any further assignments thereof to the Company or persons designated by it. The foregoing obligation to assist the Company shall continue beyond the termination of my employment, but the Company shall compensate me at a reasonable rate after such termination for time actually spent by me at the Company’s request on such assistance.

As a matter of record, I attach hereto a complete list of all inventions or improvements relevant to the subject matter of my employment by the Company Group which have been conceived, made, or reduced to practice by me, alone or jointly with others, prior to my engagement by the Company Group which I desire to remove from the operation of this Agreement. I covenant that such list is complete. If no such list is attached to this Agreement, I represent that I have no such inventions and improvements at the time of signing this Agreement.

A-3

I represent that my performance of all of the terms of this Agreement and as an employee of the Company Group does not and will not breach any agreement to keep in confidence proprietary information of any third party acquired by me in confidence or in trust prior to my employment by the Company Group. I have not entered into, and I agree that I will not enter into, any agreement either written or oral, in conflict herewith.

I understand that, as part of the consideration of the offer of employment extended to me by the Company or of my continued employment by the Company Group, as the case may be, I will not bring, have not brought, with me to the Company Group and I will not use, have not used, in the performance of my responsibilities at the Company Group, materials or documents of a former employer, unless I have obtained written authorization from the former employer for their possession and use. Accordingly, this is to advise the Company that the only materials that I will bring to the Company Group or use in my employment are identified on the attached sheet and, as to each such item, I represent that I have obtained, prior to the effective date of my employment with the Company Group, written authorization for their possession and use in my employment with the Company Group. I also understand that, in my employment with the Company Group, I am not to breach any obligation of confidentiality that I have to former employers, and I agree that I shall fulfill all such obligations during my employment with the Company Group.

This Agreement shall be effective as of the first day of my employment by the Company Group. I understand and agree that this Agreement is not a contract of employment.

10.

This Agreement shall be binding upon me, my heirs, executors, assigns, administrators, and other legal representatives and shall inure to the benefit of the Company, its successors and assigns.

Exhibit B

(Non-Competition and Non-Solicitation Agreement)

This Non-Competition and Non-Solicitation Agreement (the “Agreement”) is made and entered into this 4th day of August, 2021 (the “Effective Date”) by and between Y.S. Babu (the “Employee”) and the member of the Company Group (as defined below) employing Employee (the “Company”). The Company and Employee are sometimes referred to in this Agreement individually as a “Party” and collectively as “Parties.”

WHEREAS, the Company is a member of the Company Group which is comprised of BioCryst Pharmaceuticals, Inc. and its existing and future subsidiaries and affiliates (individually or collectively, “Company Group”). For the purposes of this Agreement, employment with the Company Group shall mean employment by any member of the Company Group. Throughout this Agreement, BioCryst Pharmaceuticals, Inc. may be referred to as “Parent;”

WHEREAS, Employee is continuing employment with the Company pursuant to an Amended and Restated Employment Agreement entered into between Employee and the Company (the “Employment Agreement”) and is simultaneously entering into an Employee’s Proprietary Information and Inventions Agreement (the “PIIA”) with a member of the Company Group; and

WHEREAS, in consideration for Employee’s promises and obligations set forth herein, the Company is offering Employee severance pay as specifically described in the Employment Agreement, including that portion of the severance pay set forth in Section 4(b)(ii) of the Employment Agreement to which Employee was not previously entitled.

NOW THEREFORE, in consideration of the mutual promises and obligations set forth below and other good and valuable consideration, the receipt and sufficiency of which the Parties acknowledge, the Company and Employee agree as follows:

COMPANY BUSINESS AND PROTECTABLE INTERESTS. Employee acknowledges that: (i) by virtue of Employee’s position with the Company, Employee will have access to Proprietary Information, as that term is defined in the PIIA, which information has not become publicly available through no fault of Employee (“Confidential Information”); (ii) the Company Group is currently engaged primarily, but not exclusively, in the business of the discovery, development and commercialization of medicines and programs for rare diseases (the “Business”); (iii) during the course of Employee’s employment, the Company Group’s Business may expand or change, in which case, such expansions or changes shall correspondingly expand or (if abandoned) contract the definition of “Business” and Employee’s obligations under this Agreement; (iv) due to the nature of the Business, Confidential Information developed by the Company Group in furtherance of the treatment for a particular rare disease would have commercial value to any other entity pursuing the development of medicines for the same disease regardless of the location of that entity, and the use of that information by such an entity would have a negative commercial impact on the Company Group; (v) the Company Group has clients, customers and collaborative partners throughout the United States and the world and the specific location of a competing business is not necessarily relevant to the capacity of that business to compete with the Company Group; and (vi) the provisions of this Agreement are reasonably necessary to protect the Company Group’s legitimate business interests, are reasonable as to time, territory and scope of activities which are restricted, do not interfere with public policy or public interest and are described with sufficient accuracy and definiteness to enable Employee to understand the scope of the restrictions imposed upon Employee.

COMPETITIVE BUSINESS ACTIVITIES.

(a)

Employee agrees that during the period of Employee’s employment with the Company Group and for a period of time ending on the date occurring one year after the date such Employee is no longer employed by any member of the Company Group (irrespective of the circumstances of such termination), Employee will not:

(i)

on Employee’s own or another’s behalf, whether as an officer, director, manager, stockholder, partner, member, associate, owner, employee, consultant, or otherwise do any of the following or provide material assistance to any other party or entity to do so:

(A)

(d)

Notwithstanding the foregoing, Employee’s ownership, directly or indirectly, of not more than one percent of the issued and outstanding stock of a corporation the shares of which are regularly traded on a national securities exchange or in the over-the-counter market shall not violate Section 2(a).

For the avoidance of doubt, and notwithstanding any provision of this Agreement to the contrary, a transfer or assignment of employment, or an assignment of this Agreement, from the Company to a member of the Company Group or from one member of the Company Group to another member of the Company Group (in one or multiple instances), shall not be a termination of employment for the purposes of triggering the one-year post-employment competitive business restrictions set forth above.

REMEDIES. Employee acknowledges that Employee’s failure to abide by this Agreement would cause irreparable harm to the Company Group for which legal remedies would be inadequate. Therefore, in addition to any legal or other relief to which the Company Group may be entitled by virtue of Employee’s failure to abide by these provisions; the Company Group, or any member thereof, may seek equitable relief, including, but not limited to, preliminary and permanent injunctive relief, for Employee’s actual or threatened failure to abide by these provisions, and Employee will indemnify the Company Group for all expenses including attorneys’ fees in seeking to enforce these provisions.

TOLLING. The period during which Employee must refrain from the activities set forth in Section 2(a) shall be tolled during any period in which Employee fails to abide by such provisions.

VIOLATION BY COMPANY. In the event that Employee alleges and proves a violation by the Company Group of any obligation of the Company Group to Employee by agreement or operation of law, such violation shall not excuse Employee from Employee’s obligations pursuant to this Agreement, but rather Employee shall be entitled to remedies available for the specific violation alleged and proven.

OTHER AGREEMENTS. Nothing in this Agreement shall terminate, revoke, or diminish Employee’s obligations or the Company Group’s rights and remedies under law or pursuant to the PIIA, relating to trade secrets or proprietary information.

ENTIRE AGREEMENT. This Agreement, the PIIA, and the Employment Agreement together constitute the exclusive and complete agreement between the Parties with respect to this subject matter with respect to severance as a result of change in control and supersedes any other right of the Employee to severance under any plan, arrangement or agreement of the Company. No change or modification of this Agreement shall be valid or binding upon the Parties unless such change or modification is in writing and is signed by the Parties.

B-4

WAIVER OF BREACH. The Company’s or Employee’s waiver of any breach of a provision of this Agreement shall not waive any subsequent breach by the other Party.

SEVERABILITY. If a court of competent jurisdiction holds that any provision or sub-part thereof contained in this Agreement is invalid, illegal, or unenforceable, that invalidity, illegality, or unenforceability shall not affect any other provision in this Agreement. Additionally, if any of the provisions of this Agreement are held unenforceable by a court of competent jurisdiction, then the Parties desire that such provision, clause, or phrase be “blue-penciled” or rewritten by the court to the extent necessary to render it enforceable.

The assignee shall assume the Company’s obligations attendant to the rights being assigned. In the event this Agreement is assigned to any member of the Company Group, or in the event a successor-in-interest to either the Company or any member of the Company Group becomes Employee’s employer under this Agreement, then the following shall apply from and after the effective date of the assignment or transfer of rights to the successor-in-interest, as the case may be: all references in this Agreement to the Company shall be deemed to mean the assignee or successor-in-interest, as the case may be, without any need for an amendment to accomplish such substitution.

(c)

Employee irrevocably consents to any such assignment and the substitution of the assignee for the Company as to rights that are assigned, and Employee also irrevocably consents to the discharge of the Company as to any obligations or liabilities under or by reason of this Agreement arising on or after the date of the assignment. In the event of any assignment from the Company to a member of the Company Group, the Company shall be an intended third-party beneficiary of this Agreement with rights to enforce the terms of this Agreement to the maximum extent allowed by law.

GOVERNING LAW.
