You also must convert the service on those devices to a new service plan in your own name.

You acknowledge and reaffirm the validity of the Inventions, Non-Disclosure and Non-Solicitation Agreement (the “Confidentiality Agreement”) that you previously signed. By signing this Agreement, you acknowledge and agree that you have had access during your employment with the Company to confidential and proprietary information of the Company and its affiliates (“Trade Secrets”), and further acknowledge and agree that the release or disclosure of any of the Trade Secrets will cause irreparable injury. By signing this Agreement, you acknowledge that you have not used or disclosed, and agree that you will not at any time use or disclose, directly or indirectly, to any other entity or person, any Trade Secrets of the Company, its affiliates, or any officers, directors or employees. You also agree that you will not attempt to gain access to such information through restricted means. You understand that the Company would not provide you with the monies and benefits under this Agreement but for your affirmation of the obligations under the Confidentiality Agreement. You further understand and agree that a violation of this provision is a material breach of this Agreement and may be enforceable against the person making disclosure by injunctive relief and by an award of damages.

In addition to your continuing obligations set forth in the Confidentiality Agreement, you also promise and agree not to disclose the contents and terms of this Agreement except to your immediate family members and your legal and financial advisors, provided they agree to keep the information confidential, or as otherwise required by law. You understand that the Company would not provide you with the monies and benefits under this Agreement but for your agreement to keep the Agreement confidential. You further understand

and agree that a violation of this provision is a material breach of this Agreement and may be enforceable against the person making disclosure by injunctive relief and by an award of damages.

You agree that you will not disparage or defame the Company or its affiliates in any respect or make any negative comments concerning your employment relationship with the Company the termination thereof, or the matters contained in this Agreement.

This Agreement shall not in any way be construed as an admission by the Company of any liability or unlawful conduct whatsoever.

You agree to make yourself available at reasonable times and places to fully cooperate and assist the Company: (a) with the transition of your duties and responsibilities; (b) with any examination of the Company or its affiliates conducted by regulatory authorities or administrative agencies having jurisdiction over the Company or its affiliates; (c) with any internal investigations or audits; and (d) in investigating and defending any action, proceeding, claim, or complaint of any kind against the Company or its affiliates. The Company will reimburse you for reasonable out-of-pocket expenses associated with requests for assistance under this provision, including travel, lodging, and meals. Any cooperation and assistance required of you under this paragraph will occur, to the extent practicable, via telephone and in such a manner as will minimize interference with your other work or personal obligations.

In the event that any provision of this Agreement is found to be illegal or unenforceable, such provision shall be severed or modified to the extent necessary to make it enforceable, and as so severed or modified, the remainder of this Agreement shall remain in full force and effect. This Agreement shall be governed and construed in accordance with the laws of the State of New York.

This Agreement will be construed and administered to preserve the exemption from Section 409A (“Section 409A”) of the Internal Revenue Code of 1986, as amended (the “Code”), of payments that qualify as short-term deferrals pursuant to Treas. Reg. § 1.409A-1(b)(4) or that qualify for the two-times compensation separation pay exemption of Treas. Reg. § 1.409A-1(b)(9)(iii) to the greatest extent possible. It is intended that all payments hereunder shall comply with Section 409A and the regulations promulgated thereunder so as not to subject you to payment of interest or any additional tax under Section 409A. In furtherance thereof, if payment or provision of any amount or benefit hereunder that is subject to Section 409A at the time specified herein would subject such amount or benefit to any additional tax under Section 409A, the payment or provision of such amount or benefit shall be postponed to the earliest commencement date on which the payment or provision of such amount or benefit could be made without incurring such additional tax. In addition, to the extent that any regulations or other guidance issued under Section 409A (after application of the previous provisions of this Section) would result in you being subject to the payment of interest or any additional tax under Section 409A, the Parties agree, to the extent reasonably possible, to amend this Agreement in order to avoid the imposition of any such interest or additional tax under Section 409A, which amendment shall have the minimum economic effect necessary and be reasonably determined in good faith by the Company and you. For purposes of Section 409A, the right to a series of installment payments under

this Agreement is to be treated as a right to a series of separate payments. The Company has recommended that you review the tax consequences of the payments to be made under this Agreement with your personal tax advisor prior to executing this Agreement. You acknowledge that you had the opportunity to review and discuss the tax consequences of the payments to be made under this Agreement with your personal tax advisor prior to execution of this Agreement. You further acknowledge and agree that, except as stated in this Agreement, the Company has made no representation to you as to the tax treatment of the compensation and benefits provided pursuant to this Agreement and that you are solely responsible for all taxes due with respect to such compensation and benefits.

This Agreement, together with the agreements specifically incorporated herein, constitute the entire agreement between you and the Company and may not be modified in any way except by written agreement signed by you and an authorized representative of the Company. This Agreement supersedes any and all other written and oral agreements and understandings between the parties; provided that the Change of Control Agreement dated as of June 4, 2013 between you and Greatbatch, Inc. shall continue in effect in accordance with its terms. You are not eligible for any other payment or benefits except for those expressly described in this Agreement.
