This Transition, Separation and Release Agreement (the “Agreement”), dated March 24, 2021, is made by and between Omar Javaid (“you”) and Vonage Holding Corporation (together with Vonage America, Inc. the “Company”). This Agreement is effective on the 8th day after you sign it, provided you do not revoke it before that day in accordance with Section 8(b) of this Agreement (the “Effective Date”). If you do not sign this Agreement by 21 days from the date it was first presented to you (the “Expiration Date”), it will be null and void and can no longer be accepted by you.

1.Separation Date. Your last day of employment with the Company will be May 31, 2021 or such other date that your employment is terminated in accordance with Section 2 of this Agreement. The actual date of your employment with the Company ends is the “Separation Date.” On the Separation Date, the Company will provide you with your final paycheck, which will include your final wages through the Separation Date, less applicable taxes and withholdings, in accordance with applicable law. You will not represent yourself as being an employee, officer, attorney, agent, or representative of the Company for any purpose after the Separation Date. The Company will reasonably consult with you on the initial internal and external announcements regarding your transition and departure.

2.Transition. During the period between the date of this Agreement and the Separation Date (the “Transition Period”), you shall (i) be placed on “garden leave”, meaning that you shall not be required to perform any employment duties other than to aid in the transition by being reasonably available remotely to answer questions that may arise during such period and (ii) continue to abide by all of the Company’s general policies and procedures in effect from time to time. Your employment with the Company will only be terminated by the Company prior to May 31, 2021 for (i) a material breach of this Agreement without cure after 5 days’ written notice by the Company detailing the nature of the breach, (ii) a breach of the ECA (as defined in Section 11 below) without cure after 5 days’ written notice by the Company detailing the nature of the breach, or (iii) Cause as defined in Section 5 of the Offer Letter between you and the Company dated June 7, 2015. The Company acknowledges that it is not aware of any such breach or event of Cause prior to its execution of this Agreement. During the Transition Period, you will continue to receive your regular salary, payable in accordance with the Company’s normal payroll practices and remain eligible for the Company’s standard benefits, subject to the terms and conditions of the plans. Upon mutual agreement in a writing signed by you and the CEO, the parties may amend the Separation Date to select a later date and extend the Transition Period. Your employment with the Company will be at-will during any extension of the Transition Period beyond May 31, 2021. For the sake of clarity, the Company acknowledges that you may spend some portion of your business time during the Transition Period on your search for new employment.

3.Severance. If you: (i) execute, do not revoke, and comply with this Agreement; (ii) execute and do not revoke the Certificate of Reaffirmation (attached to this Agreement as Exhibit A) on or after the Separation Date per its terms; and (iv) continue to comply with the terms of this Agreement, including your obligations in Sections 10, 11, and 12, the Company will provide you with the following benefits (collectively, the “Severance Benefits”):

b.If you timely elect continued coverage under COBRA for yourself and your covered dependents under the Company’s group health plans, then the Company will reimburse you for the out-of-pocket expenses you incur from COBRA premiums that are necessary to continue you and your covered dependents’ health insurance coverage at the contribution level in effect on the Separation Date, as may be amended pursuant to Section 2 of this Agreement, until the earliest of: (1) 12 months following the Separation Date; (2) the date you become eligible for health insurance coverage from a new employer; or (3) the date you are no longer eligible to continue coverage under COBRA. You will need to submit proof of payment of COBRA premiums to Benefits@vonage.com with a cc: to the Chief Human Resources Officer and/or Chief Legal Officer, within thirty (30) days of paying such amounts. The Company will reimburse you for payment of such COBRA premiums within thirty (30) days of receiving proof of such payments.

4.Health Insurance. Your benefits under the Company’s group health plans will continue until the Separation Date, as may be amended pursuant to Section 2 of this Agreement. After that date, as provided by the Consolidated Omnibus Budget Reconciliation Act (“COBRA”) and by the Company’s current group health insurance policies, you will be eligible to continue your health insurance benefits at your own expense (except as set forth in Section 3(b)) and, later, to convert to an individual policy if you wish. You will be provided with a separate notice of your COBRA rights.

5.Equity. Pursuant to the terms of the Vonage Holdings Corp. Amended and Restated 2015 Equity Incentive Plan and other equity incentive plans of the Company, as applicable (the “Equity Plans”), and the restricted stock unit award notices and agreements issued to you thereunder (the “RSU Agreements”), vesting of your restricted stock units (“RSUs”) and performance-based restricted stock units (“PRSUs”) will continue through the Transition Period

and cease vesting on the Separation Date. The RSUs and PRSUs remain subject to the terms and conditions of the Equity Plans and RSU Agreements. Any RSUs or PRSUs that remain unvested as of the Separation Date will be forfeited pursuant to the RSU Agreements and the Equity Plans.

13.No Admission. This Agreement does not constitute an admission by the Company or you of any wrongful action or violation of any federal, state, or local statute, or common law rights, including those relating to the provisions of any law or statute concerning employment actions, or of any other possible or claimed violation of law or rights.

16.Section 409A. All payments being made pursuant to this Agreement are intended to be exempt from the requirements of Internal Revenue Code Section 409A ("Section 409A"), and the Letter Agreement shall be interpreted and administered accordingly. The Separation Date is intended to be a "separation from service" for purposes of Section 409A. If an amount is to be paid in installments, then each installment shall be treated as a separate and distinct payment for purposes of Section 409A. The parties agree that this Agreement may be amended as may be necessary to fully comply with Section 409A and all related rules and regulations in order to preserve the payments and benefits provided hereunder.
