Dear Barbara:

This letter sets forth the terms and conditions of your termination of employment from Vonage Holdings Corp. (the “Company”) effective as of January 30, 2015 (the “Separation Date”).

You will receive the benefits described in the Separation Agreement & General Release below in exchange for the promises set forth therein.

THIS AGREEMENT (the “Agreement”) is entered into by and between Barbara Goodstein (“You” or the “Employee”) and the Company.

Your employment with the Company terminated effective as of the Separation Date. As of your Separation Date, all benefits and perquisites of employment (including but not limited to the vesting of any stock options, restricted stock units or performance shares that were granted to you) ceased, unless otherwise stated in this Agreement.

Following your Separation Date, you will be able to exercise any vested Company stock options or sell any Company stock during and after the next open trading window in accordance with the terms of the applicable equity plan and Company policy, as set forth below. You acknowledge that the termination of your employment does not entitle you to accelerated or continued vesting after your Separation Date under any Non-Qualified Stock Option Agreement, Restricted Stock Unit Agreement, the Vonage 2006 Incentive Plan, or the 2014 Long Term Incentive Plan. You acknowledge and agree that:

nonqualified stock options which, notwithstanding Section 4(a) of the applicable nonqualified stock option agreement, will terminate and be of no force or effect one hundred eighty (180) days following your Separation Date.

You acknowledge and agree that, other than the 477,097 vested and outstanding stock options specified in Subsections 1.B.(i) and 1.B.(ii) above, all other awards of stock options, restricted stock units, performance stock units or any other equity awards terminated, and are of no force or effect, as the Separation Date. You further acknowledge and agree that after your Separation Date, you remain subject to the Company’s Claw-back Policy, to which you previously agreed.

Following your Separation Date, you will be eligible to receive six (6) months outplacement assistance from the Company through Lee Hecht Harrison, which must be initiated with Lee Hecht Harrison within sixty (60) days of your Separation Date, the details of which will be provided to you under separate cover.

Your employee benefits under the Company’s employee medical, dental, vision, and prescription drug benefit programs as currently enrolled terminated at 11:59 PM ET on the last day of the month of your Separation Date. Your coverage for life insurance, short and long term disability, and any other employee benefit plans or programs terminated at 11:59 PM ET on your Separation Date. Your 401(k) contribution, if any, and the Company’s match, if any, were deducted from your final paycheck and will be deducted from any FDO payout, but not out of the Post-Employment Payment or Bonus Payment you will receive in accordance with this Agreement. At the end of the month following your Separation Date, you may be eligible for continued health insurance under COBRA, provided that you properly elect such benefits within the election period defined in your COBRA package. Provided you timely elect COBRA coverage, Vonage will fully subsidize such coverage through July 31, 2015 (a period of six (6) months from your Separation Date). Once the subsidized period ends, you may continue the coverage by remitting the monthly premiums directly to the COBRA administrator.  To the extent permitted by law, you may continue on COBRA for a total period of eighteen (18) months from your Separation Date (including the subsidized period).

You acknowledge and understand that the payments and benefits set forth in Section 2 and this Section 3 are at a minimum in accordance with the terms of your offer letter dated June 25, 2012 and are ample consideration for the General Release and Covenant Not to Sue herein. Your last regular paycheck has been paid to you, and the portion of your accrued/unused FDO payment that was not previously paid to you will be paid to you on the Company’s next normal payroll date. Your last regular paycheck, your FDO payment (if applicable) the Post-Employment Payment and the Bonus Payment constitute full payment of any obligations to you, including, but not limited to, all salary, wages, bonuses, accrued flexible days off (FDO) pay, commissions, holiday pay, severance pay, employee benefits, housing allowances, relocation costs, interest, outplacement costs, fees, reimbursable expenses, stock and any and all other benefits and compensation or payments of any nature due to you, if any, other than (a) the consideration set forth in this Agreement, and (b) any reasonable outstanding expense reimbursements submitted within thirty (30) days of your Separation Date in accordance with the Company’s standard expense reimbursement policies and practices. You agree that you are not entitled, and will not assert that you are entitled, to any other payment or amounts. You further acknowledge and represent that you received any leave to which you were entitled or which you requested, if any, under the Family Medical Leave or the NJ Family Leave Act, and that you did not sustain any workplace injury during your employment with the Company.

  

As a material inducement to the Company to enter into this Agreement and in consideration of the Company’s obligations under this Agreement, and in return for the consideration and post-termination benefits you are to receive pursuant to Sections 2 and 3 above, you, for yourself, your heirs, executors, administrators, trustees, legal representatives, successors and assigns (collectively referred to as "Releasing Party"), hereby forever fully release and discharge the Company, and each of its past and present affiliates, parents, subsidiaries and divisions, and each of their past and present directors, officers, partners, shareholders, employees and agents in their respective capacities as such, and the heirs, executors, administrators, successors and assigns of each of them (collectively referred to as the "Released Party"), from all claims, charges, demands, sums of money, actions, rights, causes of action, obligations and liabilities of any kind or of any nature whatsoever, at law or in equity, which the Releasing Party ever had, now has or hereafter can, shall or may have for,

ADEA Special Release: You acknowledge that the release of claims under the Age Discrimination in Employment Act (“ADEA”) is subject to special waiver protection. Therefore, you specifically agree that you knowingly and voluntarily release and waive any rights or claims of discrimination under the ADEA.

These releases do not release claims to enforce the terms and conditions of this Settlement Agreement and General Release, and do not release claims that cannot be released as a matter of law, including but not limited to (a) your right to file a claim or participate in a charge of discrimination by the Equal Employment Opportunity Commission, or any other local, state or federal administrative body or government agency that is authorized to enforce or administer laws related to employment, against the Company (with the understanding that any such filing or participation does not give you the right to recover any monetary damages against the Company - your release of claims herein bars you from recovering such monetary relief from the Company); (b) claims under any indemnification provisions for necessary expenditures or losses by you pursuant to applicable state law; (c) claims

prohibited from release for any claim or right on account for wages due, or to become due, or made as an advance on wages to be earned, unless payment of such wages has been made; (d) claims made under workers’ compensation or unemployment law; or (e) as set forth in applicable state law.

You understand and agree that claims or facts in addition to or different from those which are now known or believed by you to exist may hereafter be discovered, but it is your intention to release all claims you have or may have against the Company, its officers, directors, employees or agents, whether known or unknown, suspected or unsuspected.

In consideration of your agreement, covenants and the release set forth herein, the Company hereby forever fully releases and discharges you from all claims, charges, demands, sums of money, actions, rights, causes of action, obligations and liabilities of any kind or of any nature whatsoever, at law or in equity, of which the Chief Legal Officer of the Company has actual knowledge as of the date of this Agreement, provided that nothing herein shall prevent the Company from enforcing its Claw-back Policy against you.

You and the Company further agree that any and all disputes arising out of the terms, interpretation, application or alleged breach of this Agreement shall be subject to binding arbitration, which shall be conducted in Monmouth County, New Jersey, before JAMS, pursuant to its Employment Arbitration Rules and Procedures (“JAMS” Rules”). The costs of the arbitrator shall be shared equally between the parties. If any legal or equitable action or arbitration is necessary to enforce the terms of this Agreement, the prevailing party shall be entitled to a reasonable sum for attorneys’ fees and costs. Notwithstanding the foregoing, either party shall have the right to obtain provisional remedies or interim relief from a court of competent jurisdiction for any claim or controversy arising out of or related to violations of Section 8 of this Agreement. THE PARTIES HEREBY WAIVE THEIR RIGHT TO A TRIAL BY JURY AS TO THE ARBITRABLE CLAIMS.

This Agreement: (a) constitutes the sole and complete understanding and agreement between the parties hereto with respect to the matters set forth herein, and, except as provided in Section 12 hereof, there are no other agreements or understandings, whether written or oral and whether made contemporaneously or otherwise, that are binding upon the parties hereto; (b) may not be amended unless in a writing signed by the parties hereto; (c) shall be subject to, governed by and construed and enforced in accordance with the laws of the State of New Jersey, without reference to any conflicts of law principles; (d) any action to enforce the terms of this Agreement shall be brought in a court of appropriate jurisdiction sitting within the State of New Jersey; and (e) shall inure to the benefit of and be binding upon the heirs, devisees, legatees, executors, administrators, successors, assigns, officers, directors and affiliates of each of the parties hereto.

In the event that one or more provisions of this Agreement shall for any reason be held to be illegal or unenforceable, the remaining provisions shall continue in full force and effect. However, upon a finding that Sections 4 and/or 5 hereof, in whole or part, are illegal, or unenforceable, you shall be required, at the option of the Company, either to return the payment referred to in Section 2 hereof, or to execute a Release and Waiver and/or Covenant Not to Sue that is legal and enforceable.

It is intended that the provisions of this Agreement be exempt from, or comply with, Section 409A of the Internal Revenue Code of 1986, as amended, and the regulations and Treasury guidance thereunder as in effect from time to time (collectively hereinafter, “Section 409A”), and, to the maximum extent permitted, this Agreement shall be limited, construed and interpreted in accordance with such intent. For purposes of this Agreement, references to a “termination” or “termination of employment,” shall mean a “separation from service” within the meaning of Section 409A. If, as of the date of your separation from service, you are “specified employee” (within the meaning of Section 409A(a)(2)(B)), then with regard to any payment or provision of any payment or benefit that is considered to be “nonqualified deferred compensation” under Section 409A and is payable upon your separation from service, such payment or benefit shall not be made or provided until the earlier of the expiration of the six-month-and-one-day period measured from the date of your separation from service or your death. Upon the expiration of such delay period, all payments and benefits delayed pursuant to this paragraph shall be paid or reimbursed to you in a lump sum on the first business day after the delay period, and all remaining payments shall be provided in accordance with their regularly scheduled payment dates. With regard to any provision herein that provides for reimbursement of costs and expenses or in-kind benefits, except as permitted by Code Section 409A, (i) the right to reimbursement or in-kind benefits shall not be subject to liquidation or exchange for another benefit, (ii) the amount of expenses eligible for reimbursement, or in-kind benefits, provided during any taxable year shall not affect the expenses eligible for reimbursement, or in-kind benefits, to be provided in any other taxable year, provided, that, this clause (ii) shall not be violated with regard to expenses reimbursed under any arrangement covered by Section 105(b) of the Code solely because such expenses are subject to a limit related to the period the arrangement is in effect and (iii) such payments shall be made on or before the last day of your taxable year following the taxable year in which the expense occurred. For purposes of Section 409A, your right to receive any installment payment pursuant to this Agreement shall be treated as a right to receive a series of separate and distinct payments. In no event shall the Company be liable for any additional tax, interest or penalties that may be imposed on you for failing to comply with Section 409A.

Captions are inserted for each of reference only and shall not modify the meaning of any provision of this Agreement.

You acknowledge and agree that you have read and fully understand this Agreement, including the release and covenant not to sue; you assent to all of the terms and conditions of the Agreement; you have had an opportunity to consult with counsel of your choice before signing this Agreement, or have elected not to retain legal counsel; you are fully aware of the legal and binding effect of this Agreement; and you are signing this Agreement knowingly and voluntarily, without coercion, and based upon your own judgment and not in reliance upon any promises made by the Company or any Released Party other than those contained in this Agreement.

Barbara, if you wish to accept the terms of this Agreement, please sign on the line provided below and return the original to my attention no later than twenty-one (21) days following your receipt of this Agreement.

Sincerely,

/s/ Michael Porta
