Exhibit 10.3

SEVERANCE AND CHANGE OF CONTROL AGREEMENT

THIS SEVERANCE AND CHANGE OF CONTROL AGREEMENT (the “Agreement”) by and between Ingevity Corporation, a Delaware corporation (together with its Affiliated Companies, as hereinafter defined, being the “Company”), and Katherine P. Burgeson (the “Executive”) is dated as of the date set forth under the Company’s signature.

RECITALS

WHEREAS, the Board of Directors of the Company (the “Board”) has determined that it is in the best interests of the Company and its shareholders to assure that the Company will have the continued dedication and objectivity of the Executive, to provide the Executive with an incentive to continue his or her employment, and to motivate the Executive to achieve and exceed performance goals. The Board also believes it is imperative to diminish the inevitable distraction of the Executive by virtue of the personal uncertainties and risks created by certain involuntary terminations of employment absent Cause (as defined below), to encourage the Executive’s full attention and dedication to the Company currently, and to provide the Executive with compensation and benefits arrangements that are competitive with those of other corporations. In addition, the success of the Company’s business depends in part on the preservation of its confidential information, trade secrets and goodwill in the markets in which it competes. The Board and Executive have agreed to certain reasonable restrictions on Executive’s post-employment activities to protect these legitimate business interests. Therefore, in order to accomplish these objectives, the Board caused the Company to enter into this Agreement.

NOW, THEREFORE, IT IS HEREBY AGREED as follows:

(a) An acquisition by any individual, entity or group (within the meaning of Section 13(d)(3) or 14(d)(2) of the Exchange Act) (a “Person”) of beneficial ownership (within the meaning of Rule 13d-3 promulgated under the Exchange Act) of 30% or more of either (i) the then-outstanding shares of Common Stock (the “Outstanding Company Common Stock”) or (ii) the combined voting power of the then-outstanding voting securities of the Company entitled to vote generally in the election of directors (the “Outstanding Company Voting Securities”); excluding, however, the following: (A) any acquisition directly from the Company, other than an acquisition by virtue of the exercise of a conversion privilege unless the security being so converted itself was acquired directly from the Company, (B) any repurchase by the Company, (C) any acquisition by any employee benefit plan (or related trust) sponsored or maintained by the Company or any entity controlled by the Company, or (D) any acquisition pursuant to a transaction that complies with clauses (i), (ii) and (iii) of subsection (c) of this Section 1(a); or

Notwithstanding the foregoing, a change in title by itself shall not be a violation of this Section 4(a)(i); provided that the Executive continues to have responsibilities and authority that are, in the aggregate and in all material respects, comparable to those held by the Executive at the Relevant Time.

ii. Incentive Compensation Opportunities. In addition to the Annual Base Salary, the Executive shall be granted, during the Change of Control Period, cash-based and equity-based awards representing the opportunity to earn incentive compensation on terms and conditions no less favorable to the Executive, in the aggregate, than those provided generally at any time after the Effective Date to

In determining whether the Executive’s incentive compensation opportunities during the Change of Control Period meet the requirements of the preceding sentence, there shall be taken into account all relevant terms and conditions, including, without limitation and to the extent applicable, the potential value of such awards at minimum, target and maximum performance levels, and the difficulty of achieving the applicable performance goals.

iii. Savings and Retirement Plans. During the Change of Control Period, the Executive shall be entitled to participate in all savings and retirement plans, practices, policies and programs applicable generally to the Peer Executives, on comparable terms and conditions, but in no event shall such plans, practices, policies and programs provide the Executive with retirement or savings opportunities, in each case, less favorable, in the aggregate, to the Executive than those provided by the Company and the Affiliated Companies to the Executive at the Relevant Time.

v. a clearly established, willful and material violation by the Executive of the Company’s Code of Conduct; or

Prior to a termination for Cause, except in the case of a termination for (a)(ii) or in the case of a matter where there can be no reasonable opportunity to cure, the Executive shall be given notice and an opportunity to effectuate a cure as determined by the Company in its reasonable discretion.

For purposes of this provision, no act or failure to act, on the part of the Executive, shall be considered “willful” unless it is done, or omitted to be done, by the Executive in bad faith or without reasonable belief that the Executive’s action or omission was in the best interests of the Company. Any act, or failure to act, based upon authority given pursuant to a resolution duly adopted by the Board or upon the instructions of the Chief Executive Officer or a senior officer of the Company or based upon the advice of counsel for the Company shall be conclusively presumed to be done, or omitted to be done, by the Executive in good faith and in the best interests of the Company.

For purposes of this Agreement, a “Notice of Termination” means a written

7

notice which (i) indicates the specific termination provision in this Agreement relied upon; (ii) to the extent applicable, sets forth in reasonable detail the facts and circumstances claimed to provide a basis for termination of the Executive’s employment under the provision so indicated and (iii) specifies the Date of Termination (as defined below). If the Executive is terminating employment for Good Reason: (i) the Executive shall give the Company the Notice of Termination within 60 days following the event giving rise to the Executive’s Good Reason termination; and (ii) the Company shall have a period of 30 days after receiving the Notice of Termination to remedy the action or inaction on which Good Reason is based. If the Company fails to remedy the action or inaction on which Good Reason is based within such 30-day period, the Executive may terminate his or her or her employment for Good Reason within 30 days after the end of the cure period.

(d) Date of Termination. “Date of Termination” means if the Executive’s employment is terminated by the Company or by the Executive, the date of receipt of the Notice of Termination or any date within 30 days thereafter that is specified in the Notice of Termination.

8. Full Settlement.

Upon the request of the Executive, the Executive shall be afforded the opportunity to meet with the General Counsel during such thirty-day period with his legal representative.

9. Parachute Payments.

(a) Notwithstanding any other provisions of this Agreement to the contrary, in the event that it shall be determined that any payment or distribution in the nature of compensation (within the meaning of Section 280G(b)(2) of the Code) to or for the benefit of the Executive, whether paid or payable or distributed or distributable pursuant to the terms of this Agreement or otherwise (the “Payments”), would constitute an “excess parachute payment” within the meaning of Section 280G of the Code, the Company shall reduce (but not below zero) the aggregate present value of the Payments under the Agreement to the Reduced Amount (as defined below), if reducing the Payments under this Agreement will provide the Executive with a greater net after-tax amount than would be the case if no such reduction was made. The

11

Payments shall be reduced as described in the preceding sentence only if (i) the net amount of the Payments, as so reduced (and after subtracting the net amount of federal, state and local income and payroll taxes on the reduced Payments), is greater than or equal to (ii) the net amount of the Payments without such reduction (but after subtracting the net amount of federal, state and local income and payroll taxes on the Payments and the amount of Excise Tax (as defined below) to which the Executive would be subject with respect to the unreduced Payments). Only amounts payable under this Agreement shall be reduced pursuant to this Section 9, and any reduction shall be made in accordance with Section 409A of the Code.

(b) The “Reduced Amount” shall be an amount expressed in present value that maximizes the aggregate present value of Payments under this Agreement without causing any Payment under this Agreement to be subject to the Excise Tax, determined in accordance with Section 280G(d)(4) of the Code. The term “Excise Tax” means the excise tax imposed under Section 4999 of the Code, together with any interest or penalties imposed with respect to such excise tax.

(c) All determinations to be made under this Section 9 shall be made by such certified public accounting firm as may be designated by the Company (the “Accounting Firm”), which shall provide detailed supporting calculations both to the Company and the Executive within 15 business days of the receipt of notice from the Executive that there has been a Payment, or such earlier time as is requested by the Company. All fees and expenses of the Accounting Firm shall be borne solely by the Company. Any determination by the Accounting Firm shall be binding upon the Company and the Executive.

10. Nondisclosure of Confidential Information. The Executive shall hold in a fiduciary capacity for the benefit of the Company all Confidential Information. During the Employment Period and after termination of the Executive’s employment with the Company, for a five-year period, the Executive shall not, without the prior written consent of the Company or as may otherwise be required by law or legal process, communicate, disclose or use any Confidential Information to or on behalf of anyone other than the Company and those designated by it. In no event shall an asserted violation of the provisions of this Section 10 constitute a basis for deferring or withholding any amounts otherwise payable to the Executive under this Agreement.

11. Return of Company’s Property. Upon termination of employment with the Company, or at any time upon the Company's request, Executive shall promptly deliver to the Company all equipment, inventory, drawings, blueprints, manuals, letters, contracts, agreements, notes, notebook records, electronic media, reports, memoranda, formulae, all Confidential Information and all other materials relating to the Company's business, including all copies thereof, which are in the possession, custody or control of Executive.

12. Noncompetition and Nonsolicitation. Executive acknowledges and agrees that Confidential Information and Company's goodwill, Customer and Supplier relationships are among Company's most valuable business assets. Executive further acknowledges

12

that his or her position is one of trust, and that he or she will receive and have access to the highest levels of Confidential Information during the Employment Period. Accordingly, Executive expressly covenants and agrees that he or she will not, during the Restricted Period, directly or indirectly, for Executive’s benefit or the benefit of others, whether direct or indirect, as an employee, independent contractor, owner, shareholder, partner, limited partner, or otherwise:

(a) own, manage, operate, control or participate in the ownership, management, operation or control of, or be connected as an officer, employee, partner, director, independent contractor or in any other similar capacity with, or have any financial interest in, any Named Company Competitor, or aid or assist any Named Company Competitor in any manner that enhances the ability of such Named Company Competitor to develop, market, sell or provide Competitive Products or Services;

(b) in the Territory, own, manage, operate, control or participate in the ownership, management, operation or control of, or be connected as an officer, employee, partner, director, independent contractor or in any other similar capacity with, or have any financial interest in, any Company Competitor, or aid or assist any Company Competitor in any manner that enhances the ability of such Company Competitor to develop, market, sell or provide Competitive Products or Services; provided nothing in this clause (b) shall restrict Executive from employment with a division or business unit of a Company Competitor that does not provide Competitive Products or Services, or from employment with a Company Competitor where the Executive’s responsibilities and activities do not involve the development, marketing, sale or provision of Competitive Products or Services (provided further, for the avoidance of doubt, that all other terms of this Section 12 continue to apply);

(c) aid or assist any person or entity for the purpose of the development, marketing, sale or provision of Competitive Products or Services.

(d) solicit, persuade or induce any individual who is, or was at any time during the last twelve (12) months of the Executive’s employment by the Company, an employee of the Company, for the purpose of engaging in the development, marketing, sale or provision of Competitive Products or Services: (i) to terminate or refrain from renewing or extending such employment by the Company, or (ii) to become employed by or enter into a contractual relationship with the Executive or any other individual, person or entity;

(e) solicit, persuade or induce any individual, person or entity which is, or was at any time during the last twelve (12) months of Executive’s employment with the Company, a Supplier of critical components to the Company, including, for the avoidance of doubt, any Supplier of Crude Tall Oil, to terminate, reduce or refrain from renewing or extending such Supplier’s contractual or other relationship with the Company, or otherwise materially changing such Suppliers volume, terms and conditions; or

13

(f) solicit, persuade or induce any Customer or Indirect Customer: (i) to terminate, reduce or refrain from renewing, extending, or entering into contractual or other relationships with the Company with regard to the purchase of Competitive Products or Services, or (ii) to become a customer of or enter into any contractual or other business relationship with the Executive or any other individual, person or entity for the purpose of purchasing Competitive Products or Services.

Nothing in the Agreement should be read as limiting Executive from owning less than a five percent share of publicly-traded stock of any entity.

13. Inventions and Discoveries. Executive acknowledges and agrees that Executive’s work product and work in process, which includes, but is not limited to, inventions, discoveries, improvements, and business, financial, or marketing concepts (hereinafter referred to as “Employee Work Products”) that are conceived or made by Executive, either alone or in conjunction with others, shall be “works made for hire” under the U.S. Copyright Act, 17 U.S.C. §101, et seq., provided such Employee Work Products were (i) conceived or made in performance of Executive’s duties for Company; (ii) conceived or made using information received during the course of Executive’s employment with the Company, including, but not limited to, Confidential Information; (iii) used during the course of employment with the Company; and/or (iv) conceived or made using the Company’s facilities and/or equipment.

Executive agrees to disclose promptly to the Company any and all Employee Work Products and to assign all of Executive’s interest in the Employee Work Products to the Company or its designee.

14. Non-disparagement. Executive agrees that he or she will make no unfavorable or disparaging comments, orally or in writing, regarding Company, its Affiliated Companies or their operations, policies, or procedures, and that to do so will constitute a material breach of this Agreement.

(a) Trade Secrets Act. Pursuant to the federal Defend Trade Secrets Act, Executive acknowledges that he or she has been notified of the following: 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 in confidence to a Federal, State, or local government official, either directly or indirectly, or to an attorney, 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.  An individual who files a lawsuit for retaliation by an employer for reporting a suspected violation of law may disclose the trade secret to the attorney of the individual and use the trade secret information in the court proceeding, if the individual (i) files any document containing the trade secret under seal, and (ii) does not disclose the trade secret, except pursuant to court order.

(b) Government Agencies.  Notwithstanding any other provision in this Agreement, this Agreement does not prohibit Executive from: (1) filing a charge with or communicating with the National Labor Relations Board, the Equal Employment Opportunity Commission, or another federal, state or local government official for the purpose of reporting or investigating a suspected violation of law; or (2) communicating directly with the U.S. Securities and Exchange Commission about a possible securities law violation.
