EXECUTION COPY 

EMPLOYMENT AGREEMENT 

THIS EMPLOYMENT AGREEMENT (“Agreement”), is entered into this February [ ], 2010, by and between VONAGE HOLDINGS CORP.,
a Delaware corporation (the “Company”), and Barry Rowan (the “Executive”). 
 NOW, THEREFORE,
in consideration of the covenants and agreements hereinafter set forth, the parties hereto agree as follows: 
 1. Employment
and Duties. 
 (a) General. The Executive shall serve as Executive Vice President, Chief Financial Officer and Chief
Administrative Officer of the Company, reporting to the chief executive officer (the “CEO”) of the Company and, as requested by the Board of Directors of the Company (the “Board”), to the Board. The Executive shall
have the duties, responsibilities, and authority customarily held by the chief financial officer of a public corporation and, in his capacity as the chief administrative officer of the Company, such other duties, responsibilities and authority,
which initially may include investor relations, strategic planning and corporate development, and facilities, and which may be increased or decreased at the discretion of the CEO and may change from time to time. The Executive shall also perform
such other duties as the CEO or Board may from time to time require, and such other duties consistent with the general level and type of duties and responsibilities customarily associated with the positions of chief financial officer and chief
administrative officer. The Executive’s principal place of employment shall be the principal offices of the Company, currently located in the Holmdel, New Jersey area; provided, however, that the Executive understands and agrees
that he shall be required to travel from time to time for business reasons. 
 (b) Exclusive Services. For so long as
the Executive is employed by the Company, the Executive shall devote his full-time working time to his duties hereunder, shall conform to and use his good faith efforts to comply with the lawful and good faith directions and instructions given to
him by the CEO and, upon its request, the Board, and shall use his good faith efforts to promote and serve the interests of the Company. Further, the Executive shall not, directly or indirectly, render services to any other person or organization
without the consent of the Company or otherwise engage in activities that would interfere with the faithful performance of his duties hereunder. Notwithstanding the foregoing, the Executive may (i) serve on corporate boards, with the prior
consent of the CEO, and Chairman and Lead Independent Director of the Board, (ii) serve on civic or charitable boards or engage in charitable activities without remuneration therefor, and (iii) manage his personal investments, and serve as
an executor, trustee, or in a similar fiduciary capacity in connection therewith, provided that such activities do not, individually or in the aggregate, conflict materially with the performance of the Executive’s duties under this
Agreement. 
 2. Employment “At-Will”. The Executive’s employment shall commence on March 8, 2010
(the “Effective Date”) and the period from the Effective 








 EXECUTION COPY 

 

 
Date through the date of the Executive’s termination of employment, as provided herein, shall be the “Term.” Continuation of the Executive’s employment with the Company
throughout the Term shall be deemed an employment “at will” and the Executive’s employment may be terminated “at will” by either Executive or the Company. 

3. Compensation and Other Benefits. Subject to the provisions of this Agreement, the Company shall pay and provide the following
compensation and other benefits to the Executive during the Term as compensation for services rendered hereunder: 
 (a)
Base Salary. The Company shall pay to the Executive an annual base salary (the “Base Salary”) of not less than $450,000, payable in substantially equal installments at such intervals as may be determined by the Company in
accordance with its regular payroll practices for similarly situated employees, but in no event less frequently than biweekly in arrears. The Base Salary shall be reviewed for increase by the Compensation Committee of the Board in good faith, based
upon the Executive’s performance, not less often than annually. The Base Salary may be increased, but not decreased below its then current level, from time to time by the Board, and as so increased shall thereafter be the “Base
Salary.” 
 (b) One-Time Payment. The Executive shall be paid a one-time sign on bonus equal to $175,000 (the
“Sign-On Bonus”), of which $87,500 shall be paid within one week following the Effective Date and the remaining $87,500 of which shall be paid no later than August 15, 2010, subject to the Executive’s continued employment
with the Company on such payment date. If the Executive’s employment is terminated for Cause or the Executive voluntarily terminates his employment with the Company other than for Good Reason prior to the first anniversary of the Effective
Date, the Executive shall be required to repay the entire amount of the Sign-On Bonus paid to the Executive within ten (10) days following the end of the Term. 

(c) Sign-On Option Grant and Future Grant Opportunities. In connection with the Executive’s commencement
of employment, the Executive shall be awarded, on April 1st, 2010 (the “Grant Date”), a one-time sign-on nonqualified stock option grant to purchase three million (3,000,000) shares of the Company’s common stock (the
number of shares and exercise price being subject to adjustment based on subsequent stock splits, reverse stock splits, other adjustments, or recapitalizations) (the “Options”) at a price per share equal to the closing price of the
Company’s common stock on the Grant Date. The Options shall be issued pursuant to the terms and conditions of the Vonage Holdings Corp. 2006 Incentive Plan, as amended or restated from time to time (the “2006 Incentive Plan”)
and the Executive’s individual stock option agreement (the “Stock Option Agreement”), in forms substantially similar to those attached hereto as Exhibits “A” and “B.” Notwithstanding anything
to the contrary in the 2006 Incentive Plan or any stock option agreement thereunder, the following provisions of this Section 3(c) shall govern the terms of the Options (and all other outstanding options issued by the Company to the Executive
to the extent specifically provided). The Options shall vest and become exercisable as to
1/4th of the shares on each of the first,

  

 2 









 EXECUTION COPY 

 

 
second, third and fourth anniversaries of the Grant Date (each, a “Vesting Date”), subject to the Executive’s continued employment on the applicable Vesting Date;
provided, however, that all outstanding Options shall become fully vested and exercisable upon a “Change of Control” of the Company, as such term is defined in the 2006 Incentive Plan; provided, further,
that the acquisition of additional securities of the Company by any Person (as defined in the 2006 Incentive Plan) that, together with its Affiliates (as defined in the 2006 Incentive Plan), currently is the Beneficial Owner (as defined in the 2006
Incentive Plan) of twenty (20%) percent or more of the combined voting power of the Company’s outstanding securities shall not constitute a Change of Control. Upon a termination of the Executive’s employment without Cause by the
Company or by the Executive for Good Reason (in each case, as defined below and other than in the context of a Change of Control of the Company), an additional amount of the outstanding Options granted by the Company to the Executive shall become
vested and immediately exercisable as of the date of such termination in accordance with the provisions of the immediately following sentence. For each outstanding Option, such additional amount shall be equal to the number of Options that would
have vested on the next Vesting Date immediately following the date of termination, multiplied by a fraction where (1) the numerator is twelve (12) plus the number of full and fractional months that had elapsed between the Vesting
Date immediately prior to such termination and such termination date, and (2) the denominator is twelve (12). Upon a termination of the Executive’s employment by the Company without Cause or by the Executive for Good Reason, all
outstanding options granted by the Company to the Executive (whether part of the Options or not) shall (to the extent vested) remain exercisable for at least 180 days after the termination, or until the end of the term of the option, if earlier.
Upon a termination of the Executive’s employment by the Executive without Good Reason, all vested outstanding options granted by the Company to the Executive shall remain exercisable for at least 60 days after termination, or until the end of
the term of the option, if earlier. The Executive shall be considered for future equity grants based on individual and Company performance (and established in conjunction with the Company’s regular equity review cycle). 

(d) Annual Cash Bonus. The Executive shall be eligible to receive an annual, discretionary cash bonus (the “Annual
Bonus”) with a Target Bonus Opportunity (“TBO”) of up to 100% of the Executive’s then current Base Salary for the applicable year. Annual Bonus payouts are not guaranteed and are granted in the Company’s sole
discretion based on individual and Company performance. The Company performance targets applicable to the Executive’s Annual Bonus shall be in accordance with the Company’s annual bonus program as applicable to senior executives of the
Company, as in effect from time to time. Annual Bonus payouts, if any, are generally paid in March of the calendar year following the calendar year in which such payout is earned, subject to the Executive’s continued employment on such payment
date, except as otherwise provided in Section 4.

CEO, the Company will pay the full cost of the following insurance benefits for the Executive and his spouse and dependents: medical, dental, vision, basic life, accidental death and dismemberment, and core long term disability. The Executive shall

to 20 days paid time off for each fiscal year during the Term, which may be carried over to the next fiscal year during the Term to the extent permitted under the Company’s vacation policy.

(i) Temporary Housing. The Company shall pay or reimburse the cost of temporary housing (i.e., reasonable furnished housing,
including utilities, phone and internet access, whether in an apartment, house or hotel) for the Executive while the Executive is employed at the Company’s principal offices, in an amount not to exceed $6,000 per month, until the earliest of
(A) twelve (12) months from the Effective Date, (B) the end of the Term, and (C) such time, if any, as the Executive shall permanently relocate to the New Jersey area. Such housing and relocation expenses shall be paid by the
Company or reimbursed to the Executive monthly in arrears, subject to the submission to the Company of reasonable documentation evidencing such expenses and approval by the Vice President of Human Resources of the Company. 

(ii) Shipment of Household Goods. In connection with Executive’s relocation, the Company shall pay or reimburse the

reimburse the Executive for the cost of one midsize rental car until the Executive’s automobiles referred to in Section 3(h)(ii) above are shipped to the destination location. 

(iv) Home Sale Assistance. The Company shall pay or reimburse the Executive for the normal and customary broker’s commission
on the sale of the Executive’s principal residence in an amount up to 6% of the sale price of such principal residence along with reasonable, customary closing costs, transfer tax, state sales tax, documentary stamps, title insurance premiums,
recording and inspection fees, and reasonable attorney’s fees paid by the seller for the sale of the Executive’s principal residence. 

(v) Home Purchase Benefits. The Company shall pay or reimburse the Executive for a portion of the value of, and eligible closing
cost expenses (as defined in the Vonage Relocation Policy) incurred in connection with, the purchase of the Executive’s new home near the Executive’s new principal place of employment, not to exceed the lesser of (A) 1.5% of the value

 (vii) Tax Assistance. The Company shall gross up for income tax purposes any income arising from the payment or
reimbursement of expenses provided under this Section 3(h) as to which the Executive does not receive an offsetting income tax deduction so that the economic benefit is the same to the Executive as if such payment or reimbursements were
provided on a non-taxable basis to the Executive. 
 (viii) Repayment of Relocation Benefits. If the Executive is
terminated for Cause or resigns other than for Good Reason prior to the twelve (12) month anniversary of the Effective Date, the Executive shall repay to the Company, upon the Company’s written demand, the total amount of payments,

generally to other senior executives of the Company. 
 4. Termination of Employment. 

(a) Termination for Cause; Resignation Without Good Reason. 

(i) If the Company terminates the Executive’s employment for Cause, or if the Executive resigns from his employment hereunder other
than for Good Reason, the Executive shall only be entitled to payment of any unpaid Base Salary through and including the date of termination or resignation, any unpaid expense reimbursement or tax gross ups, any accrued but unused vacation, and any
other amounts or benefits required to be paid under this Agreement through the date of termination or resignation, including but not limited to those under Sections 3(f), 3(h), 3(i) and 3(j) hereof (in each case only to the extent earned or accrued
prior to such date of termination or resignation and not required to be repaid pursuant to Section 3(h)(viii)), or provided by law or under any plan, program, policy or practice of the Company (the “Other Accrued Compensation and
Benefits”). The Executive shall have no further right under this Agreement to receive any other compensation or benefits after such termination or resignation of employment. 

(ii) For purposes of this Agreement, “Cause” shall mean: (A) any act or omission that constitutes a material
breach by the Executive of his obligations under this Agreement; (B) the willful and continued failure or refusal of the Executive (not as a consequence of illness, accident or other incapacity) to perform the duties reasonably required of him
hereunder; (C) the Executive’s conviction of, or plea of nolo contendere to, (x) any felony or (y) another willful crime involving dishonesty or moral turpitude or which reflects negatively upon the Company in a material
manner or otherwise materially impairs or impedes its operations; (D) the Executive’s engaging in any willful misconduct, gross negligence or act of dishonesty with regard to the Company or his material duties, which conduct is injurious
to the Company and its subsidiaries or affiliates (collectively, the “ Company Group”); (E) the Executive’s material breach of either a material written policy of the Company or, to the extent the Executive is aware of
such rules or has been informed by the Company’s counsel, the relevant rules of any governmental or regulatory body applicable to the Company; or (F) the Executive’s refusal to follow the lawful directions of the Board; provided,
however, that no event or condition described in clauses (A), (B), (E) or (F) shall constitute Cause unless (i) the Company first gives the Executive written notice of its intention to terminate his employment for Cause and the
grounds for such termination, and (ii) such grounds for termination (if susceptible to correction) are not corrected by the Executive within thirty 

 

 6 









 EXECUTION COPY 

 

 
(30) days of his receipt of such notice (or, in the event that such grounds cannot be corrected within such thirty (30) day period, the Executive has not taken all reasonable steps within
such thirty (30) day period to correct such grounds as promptly as practicable thereafter). 
 (iii) For purposes of this
Agreement, “Good Reason” shall mean the occurrence of any of the following events without the Executive’s prior written consent: (A) a failure by the Company to timely pay material compensation due and payable to the
Executive in connection with his employment; (B) a material diminution in the Executive’s Base Salary or TBO; (C) a material diminution of the authority, duties or responsibilities of the Executive from those set forth in this
Agreement, including without limitation, ceasing to be the chief financial and chief administrative officer of the Company (or its ultimate parent following a Change of Control); (D) the Company requiring the Executive to be based at any office
or location more than fifty (50) miles from the Holmdel, New Jersey area; or (E) a material breach by the Company of its obligations under this Agreement; provided, however, that no event or condition described in clauses (A) through
(E) shall constitute Good Reason unless (x) the Executive gives the Company within sixty (60) days of the occurrence of the Good Reason event, written notice of his intention to terminate his employment for Good Reason and the grounds
for such termination, and (y) such grounds for termination (if susceptible to correction) are not corrected by the Company within thirty (30) days of its receipt of such notice (or, in the event that such grounds cannot be corrected within
such thirty (30) day period, the Company has not taken all reasonable steps within such thirty (30) day period to correct such grounds as promptly as practicable thereafter). Such termination for Good Reason by the Executive must occur
within 120 days of the occurrence of the Good Reason event. 
 (b) Termination Without Cause; Resignation for Good
Reason. 
 (i) If the Executive’s employment is terminated by the Company without Cause or the
Executive resigns for Good Reason, the Company shall pay the Executive, subject to Section 4(e) below: (A) severance pay equal to twelve (12) months of the Executive’s then-current Base Salary and an amount equal to the
Executive’s full TBO for the year of termination, each payable by the Company in installments during its regular payroll cycle over the twelve (12) month period following the Executive’s termination of employment, provided that
the first payment shall be made on the sixtieth
(60th) day after the Executive’s termination of
employment, and such first payment shall include payment of any amounts that would otherwise be due prior thereto, (B) a pro rata portion of the Executive’s Annual Bonus for the year of termination, if and to the extent that the Company

Other Accrued Compensation and Benefits. The Executive shall have no further rights under this Agreement to receive any other compensation or benefits after such termination or resignation of employment.

 (ii) If, following a termination of employment without Cause or a resignation for Good
Reason, the Executive materially breaches a provision of Section 5 or Section 7 hereof, the Executive shall not be eligible, as of the date of such material breach, for the payments and benefits described in Sections 4(b)(i)(A) or
(B) and any and all obligations and agreements of the Company with respect to such payments shall thereupon cease (and the Company shall be entitled to recoup any and all such payments and benefits previously paid or awarded to the Executive).

 (c) Termination Due to Death or Disability. The Executive’s employment with the Company shall terminate
automatically on the Executive’s death. In the event of the Executive’s disability, the Company shall be entitled to terminate his employment. In the event of termination of the Executive’s employment by reason of the Executive’s
death or disability, the Company shall pay to the Executive (or his estate, as applicable), subject to Section 4(e) below, (i) a pro rata portion of the Executive’s Annual Bonus for the year of termination, if and to the extent that
the Company achieves its performance metrics for such year, payable when bonuses are normally paid to other senior executives of the Company, but in no event later than March 15th of the year following the year to which such bonus relates, and
(ii) the Other Accrued Compensation and Benefits. For purposes of this Agreement, “disability” means that the Executive has been unable to engage in any substantial gainful activity by reason of any medically determinable
physical or mental impairment for 180 days in any one (1) year period. Notwithstanding the foregoing, in the event that as a result of absence because of mental or physical incapacity the Executive incurs a “separation from service”
within the meaning of such term under Section 409A of the Code and the regulations and guidance issued thereunder (“Section 409A”), the Executive shall on such date automatically be terminated from employment as a disability
termination. 
 (d) Release and Waiver. The Company shall not be required to make the payments and provide the benefits
provided for under Sections 4(b)(i)(A) or (B) or Section 4(c)(i) unless the Executive executes and delivers to the Company a Separation Agreement and General Release in substantially the form attached hereto as Exhibit C (the
“Release”), and such Release has become effective and irrevocable in its entirety within sixty (60) days of the Executive’s termination of employment. 

(e) Payments Subject to Section 409A. 

(i) The intent of the parties is that payments and benefits under this Agreement comply with Section 409A (except to the extent
exempt as short-term deferrals or otherwise) and, accordingly, to the maximum extent permitted, this Agreement shall be interpreted to be in compliance therewith. If the Executive notifies the Company (with specificity as to the reason therefor)
that the Executive believes that any provision of this Agreement (or of any award of compensation, including equity compensation or benefits) would cause the Executive to incur any additional tax or interest under Section 409A or the Company
independently makes such determination, the Company shall, after consulting with the Executive, reform such provision to attempt to comply with Section 409A through good faith modifications to

  

 8 









 EXECUTION COPY 

 

 
the minimum extent reasonably appropriate to conform with Section 409A. To the extent that any provision hereof is modified in order to comply with Section 409A, such modification shall
be made in good faith and shall, to the maximum extent reasonably possible, maintain the original intent and economic benefit to the Executive and the Company of the applicable provision without violating the provisions of Section 409A. If the
Executive notifies the Company (with specificity as to the reason therefor) that the Executive believes that any of the Company’s plans, programs or payroll practices would cause the Executive to incur any additional tax or interest under
Section 409A, the Company shall in good faith discuss with the Executive any proposed modifications to such plans, programs or payroll practices that are reasonably necessary to comply with Section 409A. 

(ii) A termination of employment shall not be deemed to have occurred for purposes of this Agreement providing for the payment of any
amounts or benefits that are considered “nonqualified deferred compensation” under Section 409A upon or following a termination of employment, unless such termination is also a “separation from service” within the meaning of
Section 409A and the payment thereof prior to a “separation from service” would violate Section 409A. As permitted by Treasury Regulation 1.409A-1(h)(1)(ii), 49% shall be substituted in lieu of 20% for the average level of bona
fide services performed during the immediately preceding thirty-six (36) month period in order to constitute a “separation from service”. For purposes of any such provision of this Agreement relating to any such payments or benefits,
references to a “termination,” “termination of employment” or like terms shall mean “separation from service.” 

(iii) For purposes of Section 409A, the Executive’s right to receive any installment payments pursuant to this Agreement shall
be treated as a right to receive a series of separate and distinct payments. Whenever a payment under this Agreement specifies a payment period with reference to a number of days (e.g., “payment shall be made within thirty (30) days
following the date of termination”), the actual date of payment within the specified period shall be within the sole discretion of the Company. 

(iv) If, as of the date of the “separation from service” of the Executive from the Company, the Executive is a “specified
employee” (within the meaning of that term under Section 409A(a)(2)(B), then with regard to any payment or the provision of any benefit that is specified herein as subject to this Section or is otherwise considered “nonqualified
deferred compensation” under Section 409A (whether under this Agreement, any other plan, program, payroll practice or any equity grant) and is payable upon the Executive’s separation from service, such payment or benefit shall not be
made or provided until the date which is the earlier of (A) the expiration of the six (6)-month-and-one-day period measured from the date of such “separation from service” of the Executive, and (B) the date of the
Executive’s death (the “Delay Period”) and this Agreement and each such plan, program, payroll practice or equity grant shall hereby be deemed amended accordingly. Upon the expiration of the Delay Period, all payments and
benefits delayed pursuant to this Section (whether they 
  

 9 









 EXECUTION COPY 

 

 
would have otherwise been payable in a single sum or in installments in the absence of such delay) shall be paid or reimbursed to the Executive in a lump sum with interest at the prime rate as
published in the Wall Street Journal on the first business day of the Delay Period (provided that any payment measured by a change in value that continues during the Delay Period shall not be credited with interest for the Delay
Period), and any remaining payments and benefits due under this Agreement shall be paid or provided in accordance with the normal payment dates specified for them herein. 

(v) The determination of whether and when a separation from service of the Executive from the Company has occurred shall be made in a
manner consistent with, and based on the presumptions set forth in, Treasury Regulation Section 1.409A-1(h). Solely for purposes of this Section 4(e)(v), “Company” shall include all persons with whom the Company would be
considered a single employer under Sections 414(b) and 414(c) of the Code. 
 (vi) All reimbursements and in-kind benefits
provided under this Agreement shall be made or provided in accordance with the requirements of Section 409A to the extent that such reimbursements or in-kind benefits are subject to Section 409A. All expenses or other reimbursements paid
pursuant herewith that are taxable income to the Executive shall in no event be paid later than the end of the calendar year next following the calendar year in which the Executive incurs such expense or pays such related tax. With regard to any
provision herein that provides for reimbursement of costs and expenses or in-kind benefits, except as permitted by Section 409A, the right to reimbursement or in-kind benefits shall not be subject to liquidation or exchange for another benefit,
the amount of expenses eligible for reimbursement, of 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
the foregoing clause shall not be violated without 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 such payments shall be made on or before the last day of the Executive’s taxable year following the taxable year in which the expense occurred. Any tax gross-up shall be made no later than the end of the calendar year next following the
calendar year in which the Executive remits the related tax. 
 (f) Notice of Termination. Any termination of employment
by the Company or the Executive shall be communicated by a written “Notice of Termination” to the other party hereto given in accordance with Section 22 of this Agreement. In the event of a termination by the
Company for Cause, or resignation by the Executive for Good Reason, the Notice of Termination shall (i) indicate the specific termination provision in this Agreement relied upon, (ii) set forth in reasonable detail the facts and
circumstances claimed to provide a basis for termination of the Executive’s employment under the provision so indicated and (iii) specify the date of termination, which date shall not be more than thirty (30) days after the giving of
such notice. The failure by the Executive or the Company to set forth in the Notice of Termination any fact or circumstance which contributes to a showing of Good Reason or Cause shall not waive

  

 10 









 EXECUTION COPY 

 

 
any right of the Executive or the Company, respectively, hereunder or preclude the Executive or the Company, respectively, from asserting such fact or circumstance in enforcing the
Executive’s or the Company’s rights hereunder to the extent that such fact or circumstance is on the same asserted basis within the definition for the termination. In the event of a termination by the Company without Cause, or resignation
by the Executive other than for Good Reason, the Notice of Termination shall specify the date of termination, which date shall not be less than thirty (30) days after the giving of such notice. 

(g) Resignation from Directorships and Officerships. The termination of the Executive’s employment for any reason shall
constitute the Executive’s resignation from (i) any director, officer, or employee position the Executive has with members of the Company Group, and (ii) all fiduciary positions (including as a trustee) the Executive holds with
respect to any employee benefit plans or trusts established by the Company. The Executive agrees that this Agreement shall serve as written notice of resignation in this circumstance. 

5. Confidentiality. 

(a) Confidential Information. The Executive has entered into and is subject to the Company’s Employee Confidentiality and
Innovations Agreement substantially in the form attached hereto as “Exhibit D.” 
 (b) Exclusive
Property. The Executive confirms that all Confidential Information (as defined in the Employee Confidentiality and Innovations Agreement) is and shall remain the exclusive property of the Company Group. All business records, papers and documents
kept or made by the Executive relating to the business of the Company Group shall be and remain the property of the Company Group. Upon the request and at the expense of the Company Group, the Executive shall promptly make all disclosures, execute
all instruments and papers, and perform all acts reasonably necessary to vest and confirm in the Company Group, fully and completely, all rights created or contemplated by this Section 5(b). Notwithstanding the foregoing, the Executive shall
maintain ownership and use of his rolodex and other address books. 
 6. Noncompetition. The Executive has entered into
and is subject to the Company’s Non-Compete Agreement substantially in the form attached hereto as Exhibit E. 
 7.
Non-Solicitation and Non-Hire. The Executive has agreed and now confirms that for a period commencing on the Effective Date and ending twelve (12) months following the Executive’s termination of employment with the Company (the
“Restricted Period”), other than in the good faith performance of his duties to the Company as Executive Vice President, Chief Financial Officer & Chief Administrative Officer of the Company, the Executive shall not,
directly or indirectly: (a) interfere with or attempt to interfere with the relationship between any person who is, or was during the then-most recent twelve (12) month period, an employee, officer, representative or agent

  

 11 









 EXECUTION COPY 

 

 
of the Company Group, or solicit or induce or attempt to solicit or induce any of them to leave the employ of any member of the Company Group or violate the terms of their respective contracts,
or any employment arrangements, with such entities; or (b) hire, recruit or attempt to hire any person who was employed by any member of the Company Group at any time during the then-most recent twelve (12) month period; provided,
that this clause (b) shall not apply to the recruitment or hiring of any individual whose employment with any member of the Company Group has been terminated for a period of six (6) months or longer; or (c) induce or attempt to induce
any customer, client, supplier, licensee or other business relation of any member of the Company Group to cease doing business with any member of the Company Group, or in any way interfere with the relationship between any member of the Company
Group and any customer, client, supplier, licensee or other business relation of any member of the Company Group, provided the foregoing clause (c) shall not apply to consumers. Nothing in this Section 7 shall be violated by the Executive
serving upon request as a reference, so long as he does not have a business relationship with the person to whom the reference is being given, and nothing in this Section 7 shall be violated by the Executive engaging in general advertising that
is not specifically targeted at the persons referred to in clauses (a), (b) and (c) that have a relationship with a member of the Company Group. As used herein, the term “indirectly” shall include, without limitation, the
Executive’s authorizing the use of the Executive’s name by any competitor of any member of the Company Group to induce or interfere with any employee or business relationship of any member of the Company Group. 

8. Certain Remedies. 

(a) Injunctive Relief. Without intending to limit the remedies available to either party hereto, including, but not limited to,
those set forth in Section 11 hereof, each of the parties hereto agrees that a breach of any of the covenants contained in Sections 5, 6, or 7 of this Agreement may result in material and irreparable injury to the other party for which there is
no adequate remedy at law, that it shall not be possible to measure damages for such injuries precisely and that, in the event of such a breach or threat thereof, any non-breaching party shall be entitled to seek a temporary restraining order or a
preliminary or permanent injunction, or both, without bond or other security, restraining the breaching party from engaging in activities prohibited by the covenants contained in Sections 5, 6, 7 or 10 of this Agreement or such other relief as may
be required specifically to enforce any of the covenants contained in this Agreement. Such injunctive relief in any court shall be available to the non-breaching party in lieu of, or prior to or pending determination in, any arbitration proceeding.

 (b) Extension of Restricted Period. In addition to the remedies the Company may seek and obtain pursuant to
Section 11 hereof, the Restricted Period may, in the court’s discretion, be extended by any and all periods during which the Executive shall be found by a court possessing personal jurisdiction over him to have been in violation of the
covenants contained in Sections 5 through 7 of this Agreement.

 9. Defense of Claims. The Executive agrees that, during the Term, and for a
period of six (6) months after termination of the Executive’s employment, upon request from the Company, the Executive shall cooperate with the Company in connection with any matters the Executive worked on during his employment with the
Company and any related transitional matters. In addition, the Executive agrees to cooperate with the Company in the defense of any claims or actions that are made and/or may be made by or against the Company Group, except if the Executive’s
reasonable interests are adverse to the Company Group in such claim or action. The Company agrees to promptly reimburse the Executive for all of the Executive’s reasonable travel and other direct expenses incurred, or to be reasonably incurred,
to comply with the Executive’s obligations under this Section 9. 
 10. Source of Payments. All payments
provided under this Agreement, other than payments made pursuant to a plan which provides otherwise, shall be paid in cash from the general funds of the Company, and no special or separate fund shall be established, and no other segregation of
assets shall be made, to assure payment. The Executive shall have no right, title or interest whatsoever in or to any investments which the Company may make to aid the Company in meeting its obligations hereunder. To the extent that any person
acquires a right to receive payments from the Company hereunder, such right shall be no greater than the right of an unsecured creditor of the Company. 

11. Arbitration. Any dispute or controversy arising under or in connection with this Agreement or otherwise in connection with the
Executive’s employment by the Company that cannot be mutually resolved by the parties to this Agreement and their respective advisors and representatives shall be settled exclusively by arbitration in New Jersey in accordance with the rules of
the American Arbitration Association before one arbitrator of exemplary qualifications and stature, who shall be selected jointly by an individual to be designated by the Company and an individual to be selected by the Executive, or if such two
individuals cannot promptly agree on the selection of the arbitrator, who shall be selected by the American Arbitration Association. Notwithstanding anything to the contrary contained herein, the arbitrator shall allow for discovery sufficient to
adequately arbitrate any claims, including access to essential documents and witnesses. The award of the arbitrator with respect to such dispute or controversy shall be in writing with sufficient explanation to allow for such meaningful judicial
review as is permitted by law, and that such decision shall be enforceable in any court of competent jurisdiction and shall be binding on the parties hereto. The remedies available in arbitration shall be identical to those allowed at law. The
arbitrator shall be entitled to award to the prevailing party in any arbitration or judicial action under this Agreement reasonable attorneys’ fees and any costs of the arbitration payable by such party, consistent with applicable law,
provided that no such award shall be made against the Executive unless the arbitrator finds the Executive’s positions in such arbitration or dispute to have been frivolous or taken in bad faith.

 12. Nonassignability; Binding Agreement. 

(a) By the Executive. This Agreement and any and all of the Executive’s rights, duties, obligations or interests hereunder
shall not be assignable or delegable by the Executive. 
 (b) By the Company. This Agreement and any and all of the
Company’s rights, duties, obligations or interests hereunder shall not be assignable by the Company, except as incident to a reorganization, merger or consolidation, or transfer of all or substantially all of the Company’s assets and then
only if the Company’s obligations hereunder are assumed by the assignee. 
 (c) Binding Effect. This Agreement
shall be binding upon, and inure to the benefit of, the parties hereto, any successors to or permitted assigns of the Company, and the Executive’s heirs and the personal representatives of the Executive’s estate. 

13. Withholding. Any payments made or benefits provided to the Executive under this Agreement shall be reduced by any applicable
withholding taxes or other amounts required to be withheld by law or contract. 
 14. Excise Tax. 

(a) In the event it shall be determined that any payment, benefit or distribution (or combination thereof) by the Company, any of the
Company’s affiliates, one or more trusts established by the Company for the benefit of its employees, or any other person or entity, to or for the benefit of the Executive (whether paid or payable or distributed or distributable pursuant to the
terms of this Agreement, or otherwise pursuant to or by reason of any other agreement, policy, plan, program or arrangement, including without limitation any stock option, stock appreciation right, phantom equity awards or similar right, or the
lapse or termination of any restriction on the vesting or exercisability of any of the foregoing) (a “Payment”) would be subject to the excise tax imposed by Section 4999 of the Code by reason of being “contingent on a
change in ownership or control” of the Company, within the meaning of Section 280G of the Code (or any successor provision thereto) or any interest or penalties are incurred by the Executive with respect to such excise tax (such excise
tax, together with any such interest and penalties, hereinafter collectively referred to as the “Excise Tax”), then the Executive shall be entitled to receive an additional payment or payments (a “Gross-Up Payment”)
in an amount such that after payment by the Executive of all taxes (including any interest or penalties imposed with respect to such taxes), including, without limitation, any income taxes (and any interest and penalties imposed with respect
thereto) and the Excise Tax imposed upon the Gross-Up Payment, the Executive retains an amount of the Gross-Up Payment equal to the Excise Tax imposed upon the Payments. For purposes of this Agreement, the term “Reduced Amount”
shall mean the greatest amount that could be paid to the Executive such that the receipt of Payments would not give rise to any Excise Tax. Notwithstanding anything to the contrary, if it shall be determined that the Executive is otherwise entitled
to a Gross-Up Payment, but that the Payments do not exceed 115% of the Reduced Amount, then no Gross-Up Payment shall 

 

 14 









 EXECUTION COPY 

 

 
be made to the Executive and the Payments, in the aggregate, shall be reduced to the Reduced Amount. Unless the Executive shall have given prior written notice specifying a different order to the
Company to effectuate the Reduced Amount, the Payments to be reduced hereunder will we determined in a manner which has the least economic cost to the Executive, on an after-tax basis, and, to the extent the economic cost is equivalent, will be
reduced in the inverse order of when the Payment would have been made to the Executive until the reduction specified herein is achieved. The Executive’s right to specify the order of reduction of the Payments shall apply only to the extent that
it does not directly or indirectly alter the time or method of payment of any amount that is deferred compensation subject to (and not exempt from) Section 409A of the Code. 

(b) Subject to the provisions of Section 15(a) hereof, all determinations required to be made under this Section 14, including
whether and when a Gross-Up Payment is required, the amount of such Gross-Up Payment, the manner in which Payments are to be reduced, if applicable, pursuant to Section 15(a), and the assumptions to be utilized in arriving at such
determination, shall be made by a nationally recognized certified public accounting firm as may be designated by the Company, and reasonably satisfactory to the Executive (the “Accounting Firm”), which shall provide detailed
supporting calculations both to the Company and the Executive within fifteen (15) business days of the closing of the change in ownership or control of the Company, or such earlier time as is requested by the Company. All fees and expenses of
the Accounting Firm shall be borne solely by the Company. Any Gross-Up Payment, as determined pursuant to this Section 14, shall be paid by the Company to the Executive (or to the appropriate taxing authority on the Executive’s behalf)
when due immediately prior to the date the Executive is required to make payment of any Excise Tax or other taxes. If the Accounting Firm determines that no Excise Tax is payable by the Executive, it shall so indicate to the Executive in writing.
Any determination by the Accounting Firm shall be binding upon the Company and the Executive absent a contrary determination by the Internal Revenue Service or a court of competent jurisdiction; provided, however, that no such
determination shall eliminate or reduce the Company’s obligation to provide any Gross-Up Payment that shall be due as a result of such contrary determination. As a result of the uncertainty in the application of Section 4999 of the Code
(or any successor provision thereto) and the possibility of similar uncertainty regarding state or local tax law at the time of any determination by the Accounting Firm hereunder, it is possible that the amount of the Gross-Up Payment determined by
the Accounting Firm to be due to (or on behalf of) the Executive is lower than the amount actually due (“Underpayment”). In the event that the Company exhausts its remedies pursuant to Section 15(c) and the Executive thereafter
is required to make a payment of any Excise Tax, the Accounting Firm shall determine the amount of the Underpayment that has occurred as promptly as possible and notify the Company and the Executive of such calculations, and any such Underpayment
(including the Gross-Up Payment to the Executive) shall be promptly paid by the Company to or for the benefit of the Executive within five (5) business days after receipt of such determination and calculations.

 EXECUTION COPY 

 

 (c) The Executive shall notify the Company in writing of any claim by the Internal
Revenue Service that, if successful, would require the payment by the Company of any Gross-Up Payment. Such notification shall be given as soon as practicable but no later than ten (10) business days after the Executive is informed in writing
of such claim and shall apprise the Company of the nature of such claim and the date on which such claim is requested to be paid. The Executive shall not pay such claim prior to the expiration of the thirty (30) day period following the date on
which he gives such notice to the Company (or such shorter period ending on the date that any payment of taxes with respect to such claim is due). If the Company notifies the Executive in writing prior to the expiration of such period that it
desires to contest such claim, the Executive shall (i) give the Company any information which is in the Executive’s possession reasonably requested by the Company relating to such claim, (ii) take such action in connection with
contesting such claim as the Company shall reasonably request in writing from time to time, including, without limitation, accepting legal representation with respect to such claim by an attorney reasonably selected by the Company,
(iii) cooperate with the Company in good faith in order to effectively contest such claim, and (iv) permit the Company to participate in any proceedings relating to such claim; provided, however, that the Company shall bear
and pay directly all costs and expenses (including additional interest and penalties) incurred in connection with such contest and shall indemnify and hold the Executive harmless, on an after-tax basis, for any Excise Tax or income tax (including
interest and penalties with respect thereto) imposed as a result of such representation and payment of costs and expenses. Without limitation on the foregoing provisions of this Section 14(c), the Company shall control all proceedings taken in
connection with such contest and, at its sole option, may pursue or forego any and all administrative appeals, proceedings, hearings and conferences with the taxing authority in respect of such claim and may, at its sole option, either direct the
Executive to pay the tax claimed and sue for a refund or contest the claim in any permissible manner, and the Executive agrees to prosecute such contest to a determination before any administrative tribunal, in a court of initial jurisdiction and in
one or more appellate courts, as the Company shall determine; provided, further, that if the Company directs the Executive to pay such claim and sue for a refund, the Company shall pay the amount of such claim to the Executive, and
shall indemnify and hold the Executive harmless, on an after-tax basis, from any Excise Tax or income tax (including interest or penalties with respect thereto) imposed with respect to such payment or with respect to any imputed income with respect
to such payment (including the applicable Gross-Up Payment); provided, further, that if the Executive is required to extend the statute of limitations to enable the Company to contest such claim, the Executive may limit this extension
solely to such contested amount; provided, further, that the Executive shall not be required to resolve, settle or take any other action with respect to such claim unless the Executive reasonably determines that such resolution,
settlement or other action would not materially adversely impact the Executive with respect to any other issue raised by the Internal Revenue Service or other taxing authority. The Company’s control of the contest shall be limited to issues
with respect to which a Gross-Up Payment would be payable hereunder and the Executive shall be entitled to settle or contest, as the case may be, any other issue raised by the Internal Revenue Service or any other taxing authority. The

  

 16 









 EXECUTION COPY 

 

 
reimbursement of expenses incurred by the Executive due to a tax contest or litigation addressing the existence or amount of an Excise Tax liability shall be reimbursed promptly, but in no event
be made later than the end of the calendar year next following the calendar year in which the taxes that are subject of the contest or litigation are remitted to the taxing authority (or if no taxes are remitted as a result of such audit or
litigation, the end of the calendar year next following the calendar year in which the audit is completed or there is a final and nonappealable settlement or other resolution of the litigation). In addition, without extending the time of any
obligation in this Section 14, any tax Gross-Up Payment shall be made no later than the end of the calendar year next following the calendar year in which the Executive remits the related tax. 

(d) If, after the receipt by the Executive of an amount paid by the Company pursuant to this Section 14, the Executive becomes
entitled to receive any refund with respect to a Gross-Up Payment, the Executive shall promptly pay to the Company the amount of such refund received (together with any interest paid or credited thereon after taxes applicable thereto).
Notwithstanding the foregoing, in the event that the obligation to refund any amount shall be a violation of the Sarbanes-Oxley Act of 2002, such obligation to refund shall be null and void. 

(e) To the extent that the applicable regulations under Code Section 280G permits a later recalculation by the Company, or requires
a later recalculation, of whether the Payments are subject to the Excise Tax, the provisions of this Section 14 shall again be applied based upon such recalculation. 

15. Amendment; Waiver. This Agreement may not be modified, amended or waived in any manner, except by an instrument in writing
signed by both parties hereto. The waiver by either party of compliance with any provision of this Agreement by the other party shall not operate or be construed as a waiver of any other provision of this Agreement, or of any subsequent breach by
such party of a provision of this Agreement. 
 16. Governing Law. All matters affecting this Agreement, including the
validity thereof, are to be governed by, and interpreted and construed in accordance with, the laws of the State of New Jersey applicable to contracts executed in and to be performed in that State. 

17. Survival of Certain Provisions. The rights and obligations set forth in Sections 3(c), 3(d), 4(a), 4(b), 4(c), and 4(e),
Sections 5 through 11 and Section 14 hereof shall survive any termination or expiration of this Agreement. 
 18. Entire
Agreement; Supersedes Previous Agreements. This Agreement, together with the (i) Employee Confidentiality and Innovations Agreement, (ii) Non-Compete Agreement, (iii) 2006 Incentive Plan, (iv) Stock Option Agreement, and
(v) the Indemnification Agreement, dated as of February [            ], 2010, between the Company and the Executive, each as amended from time to time, contains the entire agreement
and understanding of the parties hereto with respect to the matters covered

agreements and writings shall have no further force or effect, and the parties to any such other negotiation, commitment, agreement or writing shall have no further rights or obligations thereunder. The parties hereto confirm that the Original
Agreement is hereby terminated and is of no further force or effect. 
 19. Counterparts. This Agreement may be executed
by either of the parties hereto in counterparts, each of which shall be deemed to be an original, but all such counterparts shall together constitute one and the same instrument. 

20. Headings. The headings of sections herein are included solely for convenience of reference and shall not control the meaning

 22. Severability. In the event that any court having jurisdiction shall determine that any restrictive

2006 INCENTIVE PLAN 

NONQUALIFIED STOCK OPTION AGREEMENT

 (b) To the extent not previously vested in accordance with this Section 2, in the event of a Change of Control (which,
for purposes of this Agreement, shall have the meaning set forth in Section 3(c) (or any successor section thereto) of that certain Employment Agreement, dated as of February 24, 2010, by and between the Company and the Participant, as
such agreement may be amended from time to time (the “Employment Agreement”)), the Options will fully vest and become exercisable upon such Change of Control. 

(c) To the extent not previously vested in accordance with this Section 2, in the event of a termination of the Participant’s
employment without “Cause” by the 







 
Company or by the Participant for “Good Reason” , (i) an additional amount of the then outstanding Options granted by the Company to the Participant pursuant to this Agreement
shall become vested and immediately exercisable as of the date of such termination in accordance with the provisions of the immediately following sentence and (ii) remain exercisable until they terminate in accordance with Section 4 below.
For each outstanding Option, such additional amount shall be equal to the number of Options that would have vested on the next Vesting Date immediately following the date of termination, multiplied by a fraction where (1) the numerator is 12
plus the number of full and fractional months that had elapsed between the Vesting Date immediately prior to such termination and such termination date, and (2) the denominator is 12. 

(d) To the extent not previously vested in accordance with this Section 2, in the event of the Participant’s death, the Options
will (i) vest and become exercisable as of the date thereof as to one-half the number of unvested Shares covered thereby and (ii) remain exercisable until they terminate in accordance with Section 4 below. 

(e) To the extent not previously vested in accordance with this Section 2, in the event of the Participant’s disability, the
Options will (i) vest and become exercisable as of the date thereof as to one-half the number of unvested Shares covered thereby and (ii) remain exercisable until they terminate in accordance with Section 4 below. 

(f) Notwithstanding anything to the contrary herein, if the Participant’s employment with the Company is terminated by the Company
with Cause, the Options will terminate immediately and be of no force or effect. 
 (g) To the extent vested in accordance with
this Section 2, the Options will remain exercisable until they terminate in accordance with Section 4 below. 
 (i)
For purposes of this Section 2, the terms “Cause,” “Good Reason” and “disability” shall have the respective meanings ascribed to them in the Employment Agreement.

 3. Exercise of Options 

The Options may be exercised by any means specified in Section 7(d) of the Plan, as well as by a broker cashless exercise procedure,
all of which the Committee hereby approves. 
 4. Termination of Options 

To the extent vested in accordance with Section 2 above, the Options will terminate, and be of no force or effect, upon the earliest
of: 
 (a) the date of termination of the Participant’s employment if such termination of employment is for Cause,

  

 2 








 (b) 180 days following termination of Participant’s employment by the Company without
Cause or by the Participant for Good Reason, 
 (c) 60 days following termination of Participant’s employment due to the
Participant’s resignation without Good Reason, and 
 (d) the expiration of the Option Term. 

5. Rights as Stockholder 

The Participant shall have no rights as a stockholder of the Company with respect to the Shares covered by the Options until such time as
the Option Price has been paid and the Shares have been issued and delivered to the Participant. 
 6. Transferability 

 Unless permitted by the Committee in accordance with the terms of the Plan, the Options may not be sold, transferred, pledged,
assigned, or otherwise alienated or hypothecated, other than by will or by the laws of descent and distribution, and, during the Participant’s lifetime, may be exercised only by the Participant or in the event of the Participant’s legal
incapacity, the Participant’s legal guardian or representative. 
 7. Miscellaneous 

(a) This Agreement and the rights of the Participant hereunder are subject to the terms and conditions of the Plan, as the same may be
amended from time to time, as well as to such rules and regulations as the Committee may adopt for administration of the Plan. If there is any inconsistency between the terms of this Agreement and the terms of the Plan, the Plan’s terms shall
completely supersede and replace the conflicting terms of this Agreement. 
 (b) This Agreement shall be subject to all
applicable laws, rules, and regulations, and to such approvals by any governmental agencies or national securities exchanges as may be required or, the Committee determines are advisable. The Participant agrees to take all steps the Company
determines are necessary to comply with all applicable provisions of federal and state securities law in exercising his rights under this Agreement. The Committee shall have the right to impose such restrictions on any Shares acquired pursuant to
the exercise of the Option as it deems necessary or advisable under applicable federal securities laws, the rules and regulations of any stock exchange or market upon which Shares are then listed or traded, and/or any blue sky or state securities
laws applicable to Shares. It is expressly understood that the Committee is authorized to administer, construe, and make all determinations necessary or appropriate to the administration of the Plan and this Agreement, all of which shall be binding
upon the Participant. 
 (c) The Options are intended not to provide for a “deferral of compensation” within the
meaning of Section 409A of the Code. Notwithstanding the forgoing or any provision of the Plan or this Agreement, if any provision of this Agreement or the Plan 

 

 3 








 
contravenes Section 409A of the Code or could cause the Participant to incur any tax, interest or penalties under Section 409A of the Code, the Committee may, in its sole discretion and
without the Participant’s consent, modify such provision in order to comply with the requirements of Section 409A of the Code or to satisfy the conditions of any exception therefrom, or otherwise to avoid the imposition of the additional
income tax and interest under Section 409A of the Code, while maintaining, to the maximum extent practicable, the original intent and economic benefit to the Participant, without materially increasing the cost to the Company, of the applicable
provision. 
 (d) Delivery of the Shares underlying the Options upon exercise will be subject to the Participant satisfying all
applicable federal, state, local and foreign taxes. The Company shall have authority to deduct or withhold from all amounts payable to the Participant in connection with the Options, or require the Participant to remit to the Company, an amount
sufficient to satisfy any applicable taxes required by law. The Participant shall have the right to cover the minimum statutory withholding by directing the Company to withhold Shares that would otherwise be received by him, by utilization of a
cashless broker transaction or by any other means permitted by Section 18 of the Plan. 
 (e) To the extent not preempted
by federal law, this Agreement shall be governed by, and construed in accordance with, the laws of the State of New York.

 EXHIBIT C 

CONFIDENTIAL SEPARATION AGREEMENT AND GENERAL RELEASE 

This CONFIDENTIAL SEPARATION AGREEMENT and GENERAL RELEASE (hereinafter referred to as this “Agreement”) is made and entered
into by and between Barry Rowan (“Executive”) and Vonage Holdings Corp. (defined herein to include its affiliates, subsidiaries, predecessors and successors and hereinafter referred to as “Vonage” or “the Company”),
effective as of [            ] (the “Effective Date”). Executive and Vonage are hereafter referred to as the “Parties.” 

WHEREAS, Executive was employed by Vonage as its Executive Vice President, Chief Financial Officer and Chief Administrative Officer;

 WHEREAS, Executive and Vonage entered into an Employment Agreement, dated as of
[            ] (the “Employment Agreement”); 
 WHEREAS,
[description of nature of termination]; 
 WHEREAS, Vonage and Executive have read this Agreement and have had the opportunity
to review it with their respective legal counsel; and 
 WHEREAS, Vonage and Executive desire to resolve any and all issues and
claims between them, including without limitation Executive’s employment and his separation therefrom, as well as any and all issues and claims arising from or relating to the Employment Agreement, and to reach an amicable accord and settlement
concerning their future relationship. 
 NOW, THEREFORE, in consideration of the premises and mutual promises herein contained,
it is agreed as follows: 
 1. Separation and Post-Employment Benefits. Executive ceased performing duties for Vonage on
[            ] (the “Termination Date”), and Executive’s services on any and all boards of directors, boards of trustees and executive and/or management committees of
Vonage of which he was a member ended on such date. The terms of Executive’s separation from Vonage are now being agreed to, as described herein. 

2. Salary. Executive agrees that Vonage has no obligation to make, and will not make, any additional salary payments to Executive
that have not already been paid, except for any and all earned, accrued or owed amounts, but not yet paid, to which Executive is entitled up to and including the Termination Date, including any unpaid expense reimbursement or tax gross ups, any
accrued but unused vacation and any other amounts or benefits required to be paid under the Employment Agreement or provided by law or under any plan, program, policy or practice of Vonage and not including the payments or benefits described in
Paragraph 5 below (“Other Accrued Compensation and Benefits”), payable in a lump sum within five (5) days after the revocation period described in Paragraph 18(d) below. Any further entitlement that Executive may have to compensation
or benefits, such as the payments and benefits described in Paragraph 5 below, shall be governed by the terms of this Agreement. 







 3. Non-Admission. It is specifically understood and agreed that this Agreement does
not constitute and is not to be construed as an admission or evidence of (a) any violation by Vonage or Executive, of any federal, state or municipal law, statute or regulation, or principle of common law or equity, (b) the commission by
Executive or Vonage of any other actionable wrong, or (c) any wrongdoing of any kind whatsoever on the part of Executive or Vonage, and shall not be offered, argued or used for that purpose. 

4. General Release. 

(a) In exchange for the consideration provided in this Agreement, and as a material inducement for both Parties entering into this
Agreement, Executive for himself, his heirs, executors, administrators, trustees, legal representatives, successors and assigns (hereinafter collectively referred to for purposes of this Paragraph 4 as “Executive”) hereby irrevocably and
unconditionally waives, releases and forever discharges Vonage and its past, present and future affiliates and related entities, parent and subsidiary corporations, divisions, shareholders, predecessors, future officers, directors, trustees,
fiduciaries, administrators, executives, agents, representatives, successors and assigns (hereinafter collectively referred to for purposes of this Paragraph 4 as “Vonage”) for any and all waivable claims, charges, demands, sums of money,
actions, rights, promises, agreements, causes of action, obligations and liabilities of any kind or nature whatsoever, at law or in equity, whether known or unknown, existing or contingent, suspected or unsuspected, apparent or concealed, foreign or
domestic (hereinafter collectively referred to as “claims”) which he has now or in the future may claim to have against Vonage based upon or arising out of any facts, acts, conduct, omissions, transactions, occurrences, contracts, claims,
events, causes, matters or things of any conceivable kind or character existing or occurring or claimed to exist or to have occurred prior to the Effective Date in any way whatsoever relating to or arising out of Executive’s employment with
Vonage or the termination thereof. Such claims include, but are not limited to, claims arising under the Age Discrimination in Employment Act, 29 U.S.C. § 621 et seq.; Title VII of the Civil Rights Act of 1964, 42 U.S.C. § 2000e
et seq.; the Americans with Disabilities Act of 1990, 42 U.S.C. § 12101 et seq.; the Family and Medical Leave Act of 1993, 29 U.S.C. § 2601 et seq.; the Employee Retirement Income Security Act of 1974, 29 U.S.C.
§ 1001 et seq.; the Equal Pay Act of 1963, 29 U.S.C. § 206(d); Section 806 of the Corporate and Criminal Fraud Accountability Act of 2002, 18 U.S.C. § 1681 et seq.; the Fair Credit Reporting Act, 15 U.S.C.
§1681 et seq.; any other federal, state or local statutory laws relating to employment, discrimination in employment, termination of employment, wages, benefits or otherwise, including, but not limited to, the New Jersey Law Against
Discrimination, the Conscientious Employee Protection Act, the New Jersey Wage Payment Law, the New Jersey Family Leave Act, 
  


 2 








 
all as amended; the common law of the State of New Jersey; any claim under any local ordinance, including, but not limited to, any ordinance addressing fair employment practices; any claims for
employment or reemployment by the Company; any common law claims, including but not limited to actions in tort, defamation and breach of contract; any claim or damage arising out of Executive’s employment with or separation from Vonage
(including a claim for retaliation) under any common law theory or any federal, state or local statute or ordinance not expressly referenced above; and any and all claims for counsel fees and costs. 

(b) To the fullest extent permitted by law, and subject to the provisions of Paragraphs 4(d) and 4(e) below, Executive represents and
affirms that he has not filed or caused to be filed on his behalf any claim for relief against Vonage or any releasee and, to the best of his knowledge and belief, no outstanding claims for relief have been filed or asserted against Vonage or any
releasee on his behalf. 
 (c) In waiving and releasing any and all waivable claims whether or not now known, Executive
understands that this means that, if he later discovers facts different from or in addition to those facts currently known by him, or believed by him to be true, the waivers and releases of this Agreement will remain effective in all respects —
despite such different or additional facts and his later discovery of such facts, even if he would not have agreed to this Agreement if he had prior knowledge of such facts. 

(d) Nothing in this Paragraph, or elsewhere in this Agreement, prevents or prohibits Executive from filing a claim with a government
agency, such as the U.S. Equal Employment Opportunity Commission, that is responsible for enforcing a law on behalf of the government. However, Executive understands that, because Executive is waiving and releasing, among other things, any and all
claims for monetary damages and any other form of personal relief (per Paragraph 4(a) above), Executive may only seek and receive non-monetary forms of relief through any such claim. 

(e) Nothing in this Paragraph, or elsewhere in this Agreement, is intended as, or shall be deemed or operate as, a release by Executive
of his rights under the Parties’ Indemnification Agreement, dated as of [            ], as amended from time to time (the “Indemnification Agreement”), or any other rights to
indemnification relating to his performance of services as an officer and/or director of Vonage, including but not limited to those rights to indemnification set forth in Vonage’s Certificate of Incorporation as in effect on the date hereof
(the “Certificate of Incorporation”). Notwithstanding the foregoing, the provisions of this Paragraph 4(e) are intended as recitals only and are not 

 

 3 








 
intended to provide Executive with any additional contractual rights beyond those contained in the Indemnification Agreement or the Certificate of Incorporation. Furthermore, nothing herein shall
affect Executive’s rights to Other Accrued Compensation and Benefits in accordance with the terms of this Agreement or as provided in Section 6 hereof. 

5. Consideration and Post-Employment Benefits. 

(a) Vonage, for and in consideration of the undertakings of Executive set forth herein and pursuant to Paragraph 4(b)(i) of the
Employment Agreement, and intending to be legally bound, and provided that Executive does not revoke this Agreement pursuant to Paragraph 18(d) below, agrees that Vonage will pay or provide the following to Executive, subject to Section 4(d) of
the Employment Agreement: (1) severance pay equal to twelve (12) months of the Executive’s Base Salary and an amount equal to the Executive’s full Target Bonus Opportunity (as defined in Paragraph 3(d) of the Employment
Agreement) for the year of termination, each payable by the Company in installments during its regular payroll cycle over the twelve (12) month period following the Executive’s termination of employment, provided that the first payment
shall be made on the sixtieth (60th) day after the Executive’s termination of employment, and such first payment shall include payment of any amounts that would otherwise be due prior thereto, and (2) a pro rata portion of the
Executive’s Annual Bonus for the year of termination, if and to the extent that the Company achieves its performance metrics for such year, payable when bonuses are normally paid to other senior executives of the Company, but in no event later
than March 15th of the year following the year to which such bonus relates. All payments are subject to applicable tax withholding. Executive shall be solely responsible for all taxes on the payments under this Agreement. 

(b) Notwithstanding anything to the contrary herein, if Executive materially breaches provisions of Vonage’s Employee
Confidentiality and Innovations Agreement, dated as of [    ] (the “Confidentiality Agreement”), or Section 7 of the Employment Agreement, Executive shall not be eligible, as of the date of such material breach,
for the payments and benefits described in Paragraph 5(a) above, and any and all obligations and agreements of Vonage with respect to such payments shall thereupon 

 

 4 








 
cease (and Vonage shall be entitled to recoup any and all such payments and benefits previously paid or awarded to Executive), provided, however, that no event or condition
described in the Confidentiality Agreement or Section 7 of the Employment Agreement shall constitute a breach unless (i) Vonage first gives Executive written notice of its intention to terminate his payments and benefits described in
Paragraph 5(a) above and the grounds for such loss of eligibility for payments and benefits, and (ii) such grounds for termination of payments and benefits (if susceptible to correction) are not corrected by Executive within 30 days of his
receipt of such notice (or, in the event that such grounds cannot be corrected within such 30-day period, Executive has not taken all reasonable steps within such 30-day period to correct such grounds as promptly as practicable thereafter).

 (c) In accordance with the provisions of Section 3(c) of the Employment Agreement, the Vonage Holdings Corp. 2006
Incentive Plan, as amended or restated from time to time (the “2006 Incentive Plan”) and the Executive’s individual stock option agreement (the “Stock Option Agreement”), the Parties agree that the equity described in those
agreements shall vest and become exercisable (the “Vested Equity”) in accordance with Section 3(c) of the Employment Agreement. Other than the Vested Equity, all equity awarded by Vonage to Executive has terminated and is of no
further force or effect. 
 6. Prior Agreements. This Agreement supersedes all prior agreements entered into by Vonage
and Executive, except for the following: (1) Sections 3(c), 3(d), 4(a), 4(b), 4(c), and 4(e), Sections 5 through 11 and Section 14 of the Employment Agreement, which terms survive the termination of the Employment Agreement pursuant to
Section 17 thereof, (2) the Non-Compete Agreement, (3) the Confidentiality Agreement, (4) the Stock Option Agreement, and (5) the Indemnification Agreement. [List other appropriate agreements between Vonage and Executive.]

 7. Resignation from Directorships and Officerships. Pursuant to Paragraph 4(g) of the Employment Agreement, Executive
affirms that the termination of Executive’s employment by the Executive or the Company for any reasons shall constitute the Executive’s resignation from (i) any director, officer or employee position the Executive has with the
Company, and (ii) all fiduciary positions (including as a trustee) the Executive holds with respect to any employee benefit plans or trusts established by the Company. 

8. Confidentiality of Agreement. Executive agrees to keep secret and strictly confidential the terms of this Agreement (except to
the extent this Agreement is publicly filed) and further represents and warrants that he will not disclose, make known, discuss or relay any information concerning this Agreement, or any of the discussions leading up to this Agreement, to anyone
(other than members of his immediate family, accountants or attorneys who have first agreed to keep said information confidential and to not disclose it to others), and that he has not done so. The foregoing shall not prohibit or restrict such
disclosure as required by law or in connection with Vonage’s filings with the Securities and Exchange Commission or any other governmental or regulatory body or as may be necessary for the prosecution or defense of claims relating to the
performance or enforcement of this Agreement or prohibit or restrict Executive (or Executive’s attorney) 
  

 5 








 
or Vonage from responding to any such inquiry about this settlement or its underlying facts and circumstances by the Securities and Exchange Commission, the New York Stock Exchange, any other
self-regulatory organization, or in response to a duly served and effective subpoena or discovery request in the course of any litigation. Prior to making any disclosure other than to his immediate family, accountants or attorneys, Executive shall
provide Vonage with as much notice as practicable that he has been requested or compelled to make disclosure and shall cooperate with Vonage to maintain the confidentiality of this Agreement to the fullest extent possible. 

9. Return of Property and Documents. Executive represents and warrants that he has returned, or will immediately return, to Vonage
all Vonage property (including, without limitation, any and all computers, BlackBerries, identification cards, card key passes, corporate credit cards, corporate phone cards, files, memoranda, keys and software) in Executive’s possession and
that he has not, and will not, retain any duplicates or reproductions of such items. Executive further represents and warrants that he has delivered to Vonage all copies of any Confidential Information (as defined in the Confidentiality Agreement)
in his possession or control and has destroyed all copies of any analyses, compilations, studies or other documents in his possession that contain any Confidential Information. Notwithstanding the foregoing, Executive shall maintain ownership and
use of his rolodex and other address books, and Vonage agrees to cooperate with Executive in the transfer to Executive of cell phone and BlackBerry numbers used by Executive if such numbers are registered in Vonage’s name. 

10. Notices. All notices, requests, demands and other communications hereunder to Vonage shall be in writing and shall be
delivered, either by hand, by facsimile, by overnight courier or by certified mail, return receipt requested, duly addressed as indicated below or to such changed address as Vonage may subsequently designate: 

Vonage Holdings Corp. 

23 Main Street 

Holmdel, New Jersey 07733 

Attention: Office of Chief Legal Officer 

Any such notice, request, demand or other communication to Vonage delivered in the manner specified above shall be deemed duly given only upon receipt by
Vonage. 
 All notices, requests, demands and other communications hereunder to Executive shall be in writing and shall be delivered, either by
hand, by facsimile, by overnight courier, or by certified mail, return receipt requested, duly addressed as indicated below or to such changed address as Executive may subsequently designate: 

Barry Rowan 
 at
the last address on record with Vonage 
  

 6 








 Any such notice, request, demand or other communication to Executive delivered in the manner specified above
shall be deemed duly given only upon receipt by Executive. 
 11. Severability. If, at any time after the Effective Date,
any provision of this Agreement shall be held by any court of competent jurisdiction or arbitrator to be illegal, void or unenforceable, such provision shall be of no force and effect. The illegality or unenforceability of such provision, however,
shall have no effect upon, and shall not impair the enforceability of, any other provision of this Agreement, provided, however, that upon finding that Paragraph 4(a) is illegal and/or unenforceable, Vonage shall be released from any
obligation to make any payment pursuant to Paragraph 5 of this Agreement, and Executive shall repay to Vonage any and all amounts already received pursuant to Paragraph 5. 

12. Choice of Law; Arbitration. The terms of this Agreement and all rights and obligations of the Parties, including its
enforcement, shall be interpreted and governed by the laws of the State of New Jersey, without regard to conflicts of law principles. Pursuant to Section 11 of the Employment Agreement, which is incorporated by operation thereof and reference
herein, any disputes arising out of this Agreement and which are mandatorily arbitrable shall be settled exclusively by arbitration before the American Arbitration Association at a location in New Jersey. 

13. Injunctive Relief. Notwithstanding the limited agreement to arbitrate set forth in Paragraph 12 of this Agreement, any claim
alleging breach of Paragraph 8 of this Agreement, alleging breach of Sections 5, 6 or 7 of the Employment Agreement, or alleging breach of the Confidentiality Agreement or Non-Compete Agreement may be brought in any federal or state court of
competent jurisdiction in the State of New Jersey, where the parties consent to jurisdiction and agree not to argue that it is an inconvenient forum for resolution of the claim. In accordance with Section 8 of the Employment Agreement and this
Paragraph 13 of the Agreement, a material breach of Section 5, 6 or 7 of the Employment Agreement, of Paragraph 8 of this Agreement, or of the Confidentiality Agreement or Non-Compete Agreement shall be considered to be irreparable harm, where
no adequate remedy at law would be available in respect thereof. The Parties agree that neither Party will have any obligation to post a bond to obtain said injunctive relief. 

14. Modification of Agreement. No provision of this Agreement may be modified, altered, waived or discharged unless such
modification, alteration, waiver or discharge is agreed to in writing and signed by the Parties hereto. No waiver by either Party hereto of, or compliance with, any condition or provision of this Agreement to be performed by such other Party shall
be deemed a waiver of similar or dissimilar provisions or conditions at the same or at any prior or subsequent time. 
 15.
Withholding. Vonage may withhold from amounts payable or benefits provided under this Agreement any and all federal, state and local taxes that are required 

 

 7 








 
to be withheld and reported by any applicable laws and regulations. Vonage may also withhold and report any amounts necessary pursuant to the benefit plans, policies or arrangements of Vonage or
otherwise, in accordance with any applicable Vonage policies, laws and/or regulations. 
 16. Entire Agreement; Headings.
Other than as set forth in Paragraph 6 hereof, this Agreement sets forth the entire agreement between the Parties hereto and any and all prior and contemporaneous agreements, discussions or understandings between the Parties pertaining to the
subject matter hereof, including relating to severance payments or compensation, have been and are merged into and superseded by this Agreement. The headings of the sections contained in this Agreement are for convenience only and shall not be
deemed to control or affect the meaning or construction of any provision of this Agreement. 
 17. Counterparts. This
Agreement may be executed in several counterparts, each of which will be deemed an original, but all of which will constitute one and the same instrument. 

18. EXECUTIVE ACKNOWLEDGES AND WARRANTS THAT: 

(a) he has read the terms of this Agreement and that he understands its terms and effects, including the fact that he has agreed to
release and forever discharge Vonage or any releasee from any legal action arising out of his employment relationship with Vonage, the terms and conditions of that employment relationship, and the termination of that employment relationship;

 (b) he has signed this Agreement voluntarily and knowingly in exchange for the consideration described and referenced herein,
which he acknowledges as adequate and satisfactory to him; 
 (c) he has been informed that he has the right to consider this
Agreement for a period of twenty-one (21) days from receipt prior to entering into this Agreement and he has signed on the date indicated below after concluding that this Agreement is satisfactory;

his execution of this Agreement by giving written notice to Vonage, to the attention of office of Chief Legal Officer, Vonage Holdings Corp., 23 Main Street, Holmdel, New Jersey 07733. This Agreement shall not be effective or enforceable until
Executive’s right to revoke this Agreement has lapsed; 
 (e) he has been and is hereby advised in writing by Vonage to
consult with an attorney prior to signing this Agreement and he has consulted with his attorney and fully discussed and reviewed the terms of this Agreement with his attorney; 

 

 8 








 (f) neither Vonage, nor any of its agents, representatives or attorneys have made any
representations to Executive concerning the terms or effects of this Agreement other than those contained and referenced herein; and 

(g) this Agreement shall be governed, interpreted and enforced by and under the laws of the State of New Jersey, without regard to choice

 Exhibit D 

Employee Confidentiality & Innovations Agreement 

In consideration of my employment with Vonage Holdings Corp. (“Vonage”) (if such employment has not yet commenced) or my continued employment
with Vonage, as the case may be, I agree to be bound by the terms of this Employee Confidentiality & Innovations Agreement (this “Agreement.”). I understand that as a result of my employment with Vonage (“Employment”), I
may have access to information of a confidential nature about Vonage’s business, through the delivery of documents and permitted visits to Vonage’s premises. I understand that Vonage needs to maintain the confidentiality of that
information, and I agree, as set forth below, to treat such information confidentially. 
 In addition, I understand and agree that if I develop
Innovations (as defined in this Agreement) as a result of or in connection with my Employment, Vonage will have rights in those Innovations as set forth in this Agreement. 

Terms of Agreement 

A.   Confidential Information  
  

	1.	“Confidential Information” means all information, whether written or oral, tangible or intangible, and including trade secrets and data of whatever nature,
disclosed by Vonage or any of its representatives or agents, whether before or after the date of this Agreement, or which may otherwise be made available or become known to me, which is either expressly designated by Vonage as being confidential or
is disclosed under circumstances that should reasonably indicate to me that the disclosed information ought to be treated as confidential. “Confidential Information” shall not include information which 


 

	 	(i)	becomes or has been generally available to the public other than as a result of disclosure by Vonage or its officers, advisors or employees, 


 

	 	(ii)	was in my possession from a third-party source prior to its disclosure by Vonage or its representatives, 


 

	 	(iii)	becomes available to myself from a third-party source other than Vonage or its representatives, or 


 

	 	(iv)	is independently developed by myself without use of any of the Confidential Information. The burden of establishing the availability of the foregoing exceptions shall
be on myself; 

 provided, however, that in (ii) and (iii) above the third-party source
obtained the information without violation of the rights of Vonage and all restrictions on use or disclosure of such information from that third-party source are observed by myself. 

 

	2.	I agree to use Confidential Information only for purposes directly related to my Employment. Without prior written consent of Vonage, I agree not to disclose any
Confidential Information in any manner whatsoever, in whole or in part. 

  

	3.	If I am requested or required (by oral questions, interrogatories, requests for information or documents, subpoena, civil investigative demand or similar process) to
disclose Confidential Information supplied to it, I shall promptly notify Vonage of such request(s). If, in the opinion of my legal counsel, I am compelled to disclose Confidential Information to any tribunal or else stand liable for contempt or
suffer other censure or penalty, I may do so without liability under this Agreement, provided I make reasonable efforts to have my disclosure limited to the narrowest scope practicable under the circumstances, including cooperation in any request
for a protective order and seeking to have any proceedings held in camera, with a sealed record. 

  










	4.	Upon termination of my Employment for any reason, I shall, upon request, promptly deliver to Vonage all copies of any Confidential Information in my possession or
control and shall destroy all copies of any analyses, compilations, studies or other documents in my possession that contain any Confidential Information. 


B.   Innovations  
  

	1.	“Innovations” means discoveries, developments, concepts and ideas, whether or not protectable under law, relating to Vonage’s present and
prospective business activities, the nature and extent of those business activities being known to me by reason of my Employment, such as (but not limited to) inventions, know-how, discoveries, improvements, original works of authorship, designs,
software, source code, object code, programs, formulas, processes, developments, trade secrets, trademarks, copyrights, service marks, logos and related proprietary information and materials, whether patentable, copyrightable, subject to trademark
registration, or not, and all drafts, proposals, sketches, revisions and demonstration and “beta” versions thereof, written, created, developed or produced or to be written, created, developed or produced. 


 

	2.	In consideration of my Employment, I acknowledge and agree that all Innovations created by me (either working alone or as part of a group) 


 

	 	(i)	during the term of my Employment, and 

  

	 	(ii)	within six months after the end of the term if they (a) were made using equipment, supplies, facilities or trade secret information of Vonage, or (b) were
developed at least in part on the Vonage’s time, or (c) relate either to Vonage’s present or prospective business activities known to me when the Innovation was conceived, or (d) result from any work that I perform in the course
of my employment, shall be the property of Vonage, free of any reserved or other rights of any kind on my part. To achieve that result: 

  

	 	(i)	I hereby permanently, irrevocably, exclusively and absolutely assign to Vonage all right, title and interest in and to all Innovations and all right, title and interest
in and to all patents, domain names, trade secrets, trademarks and other intellectual property derived therefrom, effective when each Innovation first becomes capable of being so assigned, transferred or vested; 


 

	 	(ii)	I agree to deliver all Innovations to Vonage no later than the end of the term of my Employment, unless Vonage requests otherwise; 


 

	 	(iii)	As to any Innovation that is a copyrightable work, I agree that such Innovation constitutes and shall constitute a work made-for-hire as defined in the United States
Copyright Act of 1976; that Vonage is and shall be the author of said work made-for hire and the owner of all rights in and to such Innovation throughout the universe, in perpetuity and in all languages, for all now known or hereafter existing uses,
media and forms, including, without limitation, the copyrights therein and thereto throughout the universe for the initial term and any and all extensions and renewals thereof; and that Vonage shall have the right to make such changes therein and
such uses thereof as it may deem necessary or desirable. To the extent that such copyrightable Innovation is not recognized as a work-made-for-hire, I hereby permanently, irrevocably, exclusively and absolutely assign, transfer and convey to Vonage,
without reservation, all of my right, title and interest throughout the universe in perpetuity in such Innovation, including, without limitation, all rights of copyright and copyright renewal in such Innovation or any part thereof; and


  

 2 









	 	(iv)	I hereby waive all rights of “droit moral” or “moral rights of authors” or any similar rights or principles of law which I may now or later have in
the Innovations. I warrant and represent that I have the right to execute this certificate, that each Innovation is and shall be new and original with me and not an imitation or copy of any other material, and that each of the Innovations does not
and shall not violate or infringe upon any common law or statutory right of any party including, without limitation, contractual rights, copyrights, trademarks, patents, service marks and rights of privacy, publicity, or any other right of any
person or entity and is not the subject of any litigation or claim that might give rise to litigation. 

  

	3.	I agree to execute such further documents and do such other act as may be required by Vonage or its successors, licensees, or assignees to evidence or effectuate
Vonage’s rights under this Agreement. Vonage’s rights in the Innovations may be assigned, licensed, or otherwise transferred. 

  

	4.	I hereby irrevocably constitute and appoint Vonage with full power of substitution, to be my true and lawful attorney to execute, acknowledge, swear and file all
instruments and documents, and to take any action which shall be deemed necessary, appropriate or desirable to perfect its rights in any Innovation created by me (working alone or as part of a group). This appointment shall be deemed to be coupled
with an interest and shall be irrevocable and survive my death, disability or bankruptcy. 

  

	5.	Except as the context otherwise requires, “Vonage” also includes all Affiliates of Vonage. “Affiliate” means any person that directly or indirectly,
controls, is controlled by, or is under common control with Vonage. 

  

	6.	This Agreement shall be construed under and governed by the laws of the State of New Jersey applicable to contracts executed and wholly performed in that state. This
Agreement constitutes the entire agreement of the parties with respect to its subject matter and may not be amended or modified except by a written instrument executed by each of the parties. No failure or delay by any party in exercising any right,
power or privilege hereunder shall operate as a waiver thereof, nor shall any single or partial exercise thereof preclude any other or further exercise thereof or the exercise of any other right, power or privilege hereunder.


  

	7.	This Agreement may be executed in any number of counterparts, each of which shall constitute an original and all of which shall constitute one and the same instrument.
This Agreement shall become effective when signed by each of the parties on any counterpart, whether or not all of the parties have signed any one counterpart.

 Execution Copy 

EXHIBIT E 

NON-COMPETE AGREEMENT 

AGREEMENT, dated this          day of March, 2010, by and between Vonage Holdings Corp. and its
subsidiaries, a Delaware corporation with principal executive offices at 23 Main Street, Holmdel, New Jersey 07733 (“Vonage”), and Barry Rowan (“Employee”). 

In consideration of Employee’s employment with Vonage or continued employment with Vonage, as the case may be, Employee agrees to be bound by the
terms of this Non-Compete Agreement (“Agreement”) as follows: 
  

	 	1.	Restriction on Competition. During the period of Employee’s employment with Vonage and for a period of twelve (12) months thereafter, Employee
will not provide services to the portion of any entity that sells and markets residential/home broadband connectivity or broadband voice service (a “Competitive Entity”) as an employee thereof or as a direct individual consultant thereto
(or through an entity specifically formed for the purpose of evading the limitations hereof) anywhere within the “Territory,” that term meaning within the United States and Canada in those States and provinces (or States and provinces
contiguous thereto) in which Vonage conducts or is substantially prepared to conduct its business on the date of Employee’s employment termination. Nothing contained in this Section 1 shall be deemed to prohibit Employee from acquiring or
holding, solely for investment, publicly traded securities of a Competitive Entity, provided such securities do not, in the aggregate, constitute more than five percent (5%) of any class or series of outstanding securities of such Competitive
Entity. 

  

	 	2.	Specific Remedies. If Employee commits a breach of any of the provisions of Section 1, Vonage shall have the right to have such provisions
specifically enforced by any court having equity jurisdiction, it being acknowledged and agreed that any such breach will cause irreparable injury to Vonage and that money damages will not provide an adequate remedy. 


 

	 	3.	 Independence, Severability and Non-Exclusivity. The right enumerated in Section 2 shall be in addition to and not in lieu of any
other rights and remedies available to Vonage at law or in equity. If any of the covenants contained in Section 1 (“Covenants”) or any part of any of them, is found by a court of competent jurisdiction to be invalid or unenforceable,
this shall not affect the remainder, or rights or remedies under this Agreement, which shall be given full effect without regard to the invalid portions. The parties intend to and do hereby confer jurisdiction on courts located within the
geographical scope of the Covenants. If any of the Covenants is held to be invalid or unenforceable because of the duration or geographical area, the parties agree that the court making such determination shall have the power to reduce the duration
and/or area and, in its reduced form, such Covenant shall then be enforceable. No such holding of 










	 	
invalidity or unenforceability in one jurisdiction shall bar or in any way affect Vonage’s right to the relief provided in Section 2 or otherwise in the courts of any other jurisdiction
within the geographical scope of the Covenants. 

  

	 	4.	Successors; Binding Agreement. This Agreement and all obligations of Employee hereunder shall inure to the benefit of, and be enforceable by, Vonage and
Vonage’s successors in interest. 

  

	 	5.	Entire Agreement. This Agreement constitutes the entire understanding between the parties hereto relating to its subject matter hereof, and supersedes all
prior negotiations, discussions, preliminary agreements and agreements relating to that subject matter. 

  

	 	6.	Law Governing. This Agreement shall be governed by and construed in accordance with the laws of the State of New Jersey (without giving effect to
conflicts of law provisions). 

 IN WITNESS WHEREOF, the parties hereto have executed this Agreement on the day and year
set forth above.
