Item 6. Indemnification of Directors and Officers

The Registrant is governed by the Delaware General Corporation Law, or DGCL. Section 145 of the DGCL provides that a corporation may indemnify any person, including an officer or director, who was or is, or is threatened to be made, a party to any threatened, pending or completed legal action, suit or proceeding, whether civil, criminal, administrative or investigative (other than an action by or in the right of such corporation), by reason of the fact that such person was or is an officer, director, employee or agent of such corporation or is or was serving at the request of such corporation as a director, officer, employee or agent of another corporation or enterprise. The indemnity may include expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by such person in connection with such action, suit or proceeding, provided such officer, director, employee or agent acted in good faith and in a manner such person reasonably believed to be in, or not opposed to, the corporation’s best interest and, for criminal proceedings, had no reasonable cause to believe that such person’s conduct was unlawful. A Delaware corporation may indemnify any person, including an officer or director, who was or is, or is threatened to be made, a party to any threatened, pending or contemplated action or suit by or in the right of such corporation, under the same conditions, except that such indemnification is limited to expenses (including attorneys’ fees) actually and reasonably incurred by such person, and except that no indemnification is permitted without judicial approval if such person is adjudged to be liable to such corporation. Where an officer or director of a corporation is successful, on the merits or otherwise, in the defense of any action, suit or proceeding referred to above, or any claim, issue or matter therein, the corporation must indemnify that person against the expenses (including attorneys’ fees) which such officer or director actually and reasonably incurred in connection therewith. The Company’s amended and restated certificate of incorporation provides that, to the fullest extent permitted by the DGCL, no director or officer will be personally liable to the Company or to its shareholders for monetary damages for breach of fiduciary duty as a director or officer, as applicable. The provisions of the Company’s amended and restated certificate of incorporation apply to an officer of the Company only if he or she is a director of the Company and is acting in his or her capacity as director, and do not apply to officers of the Company who are not directors.

The Company’s amended and restated bylaws require the Company to indemnify any person who was or is made a party or is threatened to be made a party to, or is otherwise involved in, a legal proceeding by reason of the fact that he or she is or was a director, officer or employee of Ingevity, or while a director, officer or employee of the Company, is or was serving at the Company’s request in a fiduciary capacity with another enterprise (including any corporation, partnership, joint venture, trust, or other enterprise, including service with respect to any employee benefit plans maintained or sponsored by the Company), to the fullest extent authorized by the DGCL, as it exists or may be amended, against all expense, liability or loss (including attorneys’ fees, judgments, fines, U.S. Employee Retirement Income Security Act of 1974, as amended, excise taxes or penalties and amounts paid in settlement by or on behalf of such person) reasonably incurred or suffered in connection with such service. The Company is authorized under its amended and restated bylaws to maintain directors’ and officers’ insurance protecting the Company, any director, officer or employee of ours, against any expense, liability or loss, whether or not the Company would have the power to indemnify the person under the DGCL. The Company may, from time to time, indemnify any of its agents to the fullest extent permitted with respect to directors, officers and employees in its amended and restated bylaws.

The foregoing is only a general summary of certain aspects of Delaware law and the Company’s amended and restated certificate of incorporation and bylaws dealing with indemnification of directors, officers and employees of the Company.
