Integer Holdings Corporation (hereinafter called the “Corporation”), a corporation organized and existing under the General Corporation Law of the State of Delaware, does hereby certify:

FIRST: This Certificate of Amendment (the “Certificate of Amendment”) amends the provisions of the Corporation’s Restated Certificate of Incorporation filed with the Secretary of State on August 8, 2016 (the “Restated Certificate of Incorporation”).

SECOND: This Certificate of Amendment was duly adopted by the Board of Directors and the stockholders of the Corporation in accordance with the provisions of Section 242 of the General Corporation Law of the State of Delaware as set forth in Title 8 of the Delaware Code.

THIRD: The text of the Paragraph Fifth of the Restated Certificate of Incorporation of the Corporation is hereby amended and restated to read in its entirety as follows:

FIFTH: To the fullest extent permitted by the DGCL as it currently exists or may hereafter be amended, a director or officer of the Corporation shall not be personally liable either to the Corporation or to any stockholder for monetary damages for breach of fiduciary duty as a director or officer, except (i) for any breach of the director’s or officer’s duty of loyalty to the Corporation or its stockholders, (ii) for acts or omissions by a director or officer which are not taken or omitted to be taken in good faith or which involve intentional misconduct or knowing violation of the law, (iii) for any matter in respect of which such director shall be liable under Section 174 of Title 8 of the DGCL or any amendment or successor provision thereto, (iv) for any transaction from which the director or officer shall have derived an improper personal benefit, or (v) for any officer in any action by or in the right of the Corporation. Neither the amendment nor the repeal of this paragraph FIFTH nor the adoption of any provision of this Restated Certificate of Incorporation inconsistent with this paragraph FIFTH shall eliminate or reduce the effect of this paragraph FIFTH in respect of any matter occurring, or any cause of action, suit or claim that, but for this paragraph FIFTH, would accrue or arise prior to such amendment, repeal or adoption of an inconsistent provision.

The Corporation shall indemnify any person who was or is a party or is threatened to be made a party to, or testifies in, any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative in nature, by reason of the fact that such person is or was a director, officer, employee or agent of the Corporation, or is or was serving at the request of the Corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, employee benefit plan, trust or other enterprise, against expenses (including

Such right of indemnification shall not be deemed exclusive of any other rights to which such director, officer, employee or agent may be entitled apart from the foregoing provisions.

FOURTH: All other provisions of the Restated Certificate of Incorporation shall remain in full force and effect.
