Separation of Employment and Release Agreement, dated as of December 6, 2020, between GTT Communications, Inc. and Steven Berns

    This Transition, Separation, and General Release Agreement (this “Agreement”) is entered into by and between Steven Berns (“Employee”) and GTT Communications, Inc. (the “Company,” together with Employee, the “Parties”). The Parties hereby agree as follows:

1.The Parties mutually agree that Employee’s final date of employment will be January 31, 2021 (Employee’s final date of employment, the “Separation Date”). After the Separation Date, Employee no longer will be, and will not hold himself out as, an employee, agent, or representative of the Company. Employee will be paid his current base salary in accordance with the terms and conditions of Paragraph 2 below through the Separation Date. On the Separation Date, Employee will be paid for all accrued but unused vacation. For the avoidance of doubt, the Parties acknowledge and agree that Employee’s termination constitutes a termination by Employee in accordance with Section 7.6 of the Employment Agreement between Employee and the Company dated April 6, 2020 (the “Employment Agreement”) and shall not constitute a termination by the Employee for Good Reason or by the Company with or without Cause.

2.Effective as of December 4, 2020, Employee resigned from any and all directorships, committee memberships, and any other offices that Employee holds with the Company and/or any of the other Company Entities (as defined below). During the period commencing on December 5, 2020 and ending on the Separation Date (the “Transition Period”), Employee will serve in the role of advisor to the Company and will perform duties and responsibilities as reasonably requested of Employee from time to time by the Chief Executive Officer, other members of the Company’s senior management, or the Company’s Board of Directors. During the Transition Period, the Company reserves the right, in its sole discretion, to not provide Employee with any work, alter Employee’s job duties consistent with the role of advisor, and/or relieve Employee from all job duties. Employee may continue to provide his services hereunder remotely (from his home or otherwise) and will not be required to report physically to any Company office. During the Transition Period, Employee agrees to (a) use his reasonable best efforts, ability and experience to conscientiously perform Employee’s advisor job duties, as assigned; (b) reasonably comply with and be bound by Company’s operating policies, procedures, and practices from time to time in effect, as published and generally made available to the employees of the Company; (c) comply with his obligations to the Company pursuant to Section 4 of the Employment Agreement and pursuant to the Executive Invention Assignment and Confidentiality Agreement to which he is a party; and (d) transition and transfer knowledge of Employee’s job duties to others as requested (all of the foregoing, the “Transition Duties”). Effective January 1, 2021, the foregoing Transition Duties will not exceed twenty (20) hours per week. During the Transition Period, Employee will continue to receive his base salary at the rate currently in effect as of the Effective Date and will remain eligible to participate in the Company’s benefit plans and programs in which Employee is currently eligible to participate during the Transition Period; provided, however, that Employee shall not be eligible for any bonus amounts during or after the Transition Period.

3.In consideration for signing (and not revoking) both this Agreement and the Post-Employment Release attached hereto as Annex A (which Post-Employment Release must be

signed within the twenty-one (21) day period immediately following the Separation Date, but not before the Separation Date; provided, that Employee’s obligation to execute the Post-Employment Release will be deemed waived by the Company if the Company fails to execute the Post-Employment Release on or within five (5) business days following the Separation Date), and Employee’s compliance with both this Agreement and its Annex A, including but not limited to Paragraphs 1 and 2 hereof, in full settlement of any compensation or benefits to which Employee otherwise could claim to be entitled, and in exchange for the mutual promises, covenants, releases, and waivers set forth in this Agreement and its Annex A:

    (a)    The Company will provide Employee with a cash payment in the amount of $490,000 (less required tax withholdings), payable in a lump sum via wire transfer within twenty-four (24) hours of the Effective Date (as defined below);

    (b)    Within twenty-four (24) hours of the Effective Date, the Company will pay directly to Employee’s counsel, as directed by Employee, the total amount of legal fees and expenses incurred by Employee in connection with Employee’s separation from the Company and the negotiation and execution of this Agreement, up to $25,000 (and will promptly pay to such counsel at the direction of Employee any additional reasonable fees and expenses incurred by Employee in connection with any future negotiations with the Company relating to this Agreement, including any amendments thereto); and

    (c)    The Company will provide Employee with a payment in the amount of $10,000 (less required tax withholdings), payable in a lump sum on the Company’s first regularly scheduled payroll date following the Post-Employment Release Effective Date, but in all events on or prior to March 15, 2021.

4.Employee acknowledges that Employee would not be entitled to the consideration set forth in Paragraph 3 above, but for the terms of this Agreement. Employee acknowledges and agrees that (a) the consideration provided to Employee pursuant to this Agreement (i) is in full discharge of any and all liabilities and obligations of the Company to Employee, monetarily or otherwise, with respect to his employment, and (ii) exceeds any payment, benefit, or other thing of value to which Employee might otherwise be entitled; and (b) Employee is not entitled to any bonus or deferred compensation with respect to 2020 or any other year, or any other salary, wages, awards, severance, interests, profit share, commissions, overtime, paid time off, premiums, royalties, equity, carried interest, deferred compensation, or other forms of compensation, benefits, fringe benefits, perquisites, or payments of any kind or nature whatsoever (collectively, “Compensation”), except for (x) salary and benefits earned and accrued for the current payroll period but unpaid through the Effective Date and (y) as otherwise explicitly provided in this Agreement. For the avoidance of doubt, Employee further acknowledges and agrees that any and all equity granted to the Employee, including, but not limited to, equity granted under the Company’s Employee, Directors & Consultant Stock Plan, shall automatically be forfeited.

5.Employee’s health benefits provided through the Company will continue through the Separation Date. Thereafter, pursuant to federal law, and independent of this Agreement, Employee and Employee’s eligible dependents will be entitled to elect benefit continuation coverage if Employee timely applies for COBRA benefits. Information regarding Employee’s rights under COBRA will be provided to Employee in a separate mailing. As explained more

fully in the materials Employee will receive, COBRA coverage may cease at any time Employee is deemed eligible for group health coverage from another employer.

6.In exchange for the consideration provided to Employee pursuant to Paragraph 3, above, which Employee acknowledges is fair and sufficient and exceeds any payment, benefit, or other thing of value to which Employee might otherwise be entitled, Employee hereby agrees, represents, and warrants as follows:

        (b)    Notwithstanding the foregoing, in accordance with the Defend Trade Secrets Act, 18 U.S.C. § 1833(b), and other applicable law, nothing in this Agreement, the Employment Agreement, or any other agreement or Company policy shall prevent Employee from, or expose Employee to criminal or civil liability under federal or state trade secret law for, (a) directly or indirectly sharing any trade secrets of the Company or other Confidential Information (except information protected by any of the Company Entities’ attorney-client or work product privilege) in confidence with law enforcement, an attorney, or with any federal, state, or local government agencies, regulators, or officials (including the EEOC, the Securities and Exchange Commission, or any applicable local agency), for the purpose of investigating,

reporting, or complaining of a suspected violation of law, whether in response to a subpoena or otherwise, without notice to the Company, or (b) disclosing the Company’s trade secrets in a filing in connection with a legal claim, provided that the filing is made under seal.

        (b)    The Company agrees that the Company shall instruct each member of the Company’s Board of Directors and the Company’s senior management, including but not limited to the Chief Executive Officer, the Chief Operating Officer, and the General Counsel, not to, verbally or in writing, disparage in any manner or context Employee, in any manner likely to be materially harmful to Employee, or Employee’s business reputation or personal reputation, nor shall the Company authorize, direct, or sanction any such public statement; provided that nothing herein shall in any way limit the exercise by any person of their fiduciary or corporate duties or other similar obligations or prevent any person from responding accurately and fully to any question, inquiry or request for information when required by legal process.

11.Each provision of this Agreement and its Annex A is severable from the other provisions hereof and thereof, and if any term or provision of this Agreement or its Annex A (or any portion thereof) is determined by an arbitrator or reviewing court of competent jurisdiction to be invalid, illegal, or incapable of being enforced, all other terms and provisions of this Agreement and its Annex A shall nevertheless remain in full force and effect. Upon a determination that any term or provision (or any portion thereof) is invalid, illegal, or incapable of being enforced, the Parties agree that an arbitrator or reviewing court shall have the authority to “blue pencil” or modify this Agreement and/or its Annex A so as to render it enforceable and effect the original intent of the Parties as reflected herein and therein, to the fullest extent permitted by applicable law.

12.This Agreement, including its Annex A, (a) may be executed in identical counterparts, each of which together shall constitute a single agreement; (b) shall be fairly

interpreted in accordance with its terms and without any strict construction in favor of or against either party, notwithstanding which party may have drafted it; (c) shall be governed by and construed in accordance with the laws of the State of Delaware, without regard any choice of law principles; (d) together with the Surviving Provisions, constitutes the Parties’ entire agreement, arrangement, and understanding regarding the subject matter herein, superseding any prior or contemporaneous agreements, arrangements, or understandings, whether written or oral, between Employee, on the one hand, and the Company, on the other hand, regarding the same subject matter; and (e) may not be modified, amended, discharged, or terminated, nor may any of its provisions be varied or waived, except by a further signed written agreement between the Parties. Facsimile, PDF, and other true and accurate electronic copies of this document shall have the same force and effect as originals hereof.

13.This Agreement is intended to be exempt from or satisfy, the requirements of Section 409A of the Internal Revenue Code of 1986, as amended (the “Code”), including current and future guidance and regulations interpreting such provisions, and it should be interpreted accordingly. Notwithstanding the foregoing, the Company does not guarantee that any payment hereunder complies with or is exempt from Section 409A of the Code and neither the Company, nor its executives, directors, officers, employees or affiliates shall have any liability with respect to any failure of this Agreement to comply with or be exempt from Section 409A of the Code. Each payment made under this Agreement will be treated as a separate payment for purposes of Section 409A of the Code and the right to a series of installment payments under this Agreement is to be treated as a right to a series of separate payments.

14.Each of the Parties agrees that a Party’s breach or threatened breach of this Agreement, Annex A (as applicable), or the Surviving Provisions (as applicable), may result in irreparable and continuing harm to the other Party for which there may be no adequate remedy at law. Therefore, the non-breaching Party, as appropriate, shall be entitled to seek emergency equitable relief, including a temporary restraining order and preliminary injunction, from a state or federal court of competent jurisdiction, without first posting a bond, to restrain any such breach or threatened breach. Such relief shall be in addition to any and all other remedies, including damages, available to such non-breaching Party.

15.(a)    By signing this Agreement below, Employee agrees, represents, and warrants that (i) no promise or inducement has been made to Employee other than those set forth in this Agreement, and Employee has executed this Agreement without reliance on any promises or representations by the Company or any of the other Releasees that is not included herein; (ii) Employee is fully competent to manage his personal and professional affairs, and understands that he is waiving legal rights, whether presently known or hereafter discovered, by signing this Agreement; (iii) Employee has been advised to consult with an attorney of Employee’s own choosing about this Agreement, and Employee has had an opportunity to thoroughly discuss the terms of this Agreement with such attorney, if Employee so desired; (iv) Employee is entering into this Agreement freely, knowingly, and voluntarily, without duress or coercion, and with an intent to be bound hereby; and (v) Employee fully understands the terms, conditions, and significance of this Agreement and its final and binding effect. Each of the Parties represents and warrants to the other Party that such Party has not assigned any of the Claims waived hereunder to any other person or entity.

(b)    To execute this Agreement, Employee must sign and date the Agreement below, and return a complete copy thereof, via email, to Chris McKee, General Counsel, GTT Communications, Inc., 7900 Tysons One Place, Suite 1450, McLean, Virginia 22102, Chris.McKee@gtt.net.

16.All of the terms and provisions of this Agreement shall inure to the benefit of and shall be binding upon the Parties hereto and their respective heirs, legal representatives, successors, and assigns. The Releasees are intended third-party beneficiaries to this Agreement and shall be entitled to enforce this Agreement, as applicable, in accordance with its terms.
