You hereby represent to the Company that you are under no obligation or
agreement that would prevent you from becoming an employee of the Company or
adversely impact your ability to perform the expected responsibilities. By
accepting this offer, you agree that no trade secret or proprietary information
not belonging to you or the Company will be disclosed or used by you at the
Company.

(c)
This Offer Letter is not an employment contract and does not create an implied
or express guarantee of continued employment. By accepting this offer, you are
acknowledging that you are an employee at-will. This means that either you or
the Company may terminate your employment at any time and for any reason or for
no reason. This Offer Letter contains the entire agreement and understanding
between you and the Company with respect to the terms of your employment and
supersedes any prior or contemporaneous agreements, understandings,
communications, offers, representations, warranties, or commitments by or on
behalf of the Company, whether written or oral, with respect to the terms of
your employment. Except for amendments to increase compensation payable to you,
the terms of this Offer Letter may not be amended except pursuant to a written
agreement between you and the Company.

(d)
Section 409A

(i)
The intent of the parties is that payments and benefits under this Offer Letter
comply with or be exempt from Internal Revenue Code Section 409A and the
regulations and guidance promulgated there under (collectively "Section 409A")
and, accordingly, to the maximum extent permitted, this Offer Letter shall be
interpreted to be exempt from Section 409A or in compliance therewith, as
applicable. If you notify the Company that you have received advice of tax
counsel of national reputation with expertise in Section 409A that any provision
of this Offer Letter (or of any award of compensation, including equity
compensation or benefits) would cause you to incur any additional tax or
interest under Section 409A (with specificity as to the reason thereof) or the
Company independently makes such determination, the Company shall, after
consulting with you, reform such provision to try to comply

23 Main Street | Holmdel, NJ 07733 | 732.528.2600 | www.vonage.com

--------------------------------------------------------------------------------

with Section 409A through good faith modifications to the minimum extent
reasonably appropriate to conform with Section 409A. To the extent that any
provision hereof is modified in order to comply with or be exempt from 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
you and the Company of the applicable provision without violating the provisions
of Section 409A.

(ii)
A termination of employment shall not be deemed to have occurred for purposes of
any provision of this Offer Letter 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.
For purposes of any such provision of this Offer Letter relating to any such
payments or benefits, references to a "termination," "termination of employment"
or like terms shall mean "separation from service."

(iii)
If, as of the date of your "separation from service" from the Company, you are 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 considered "nonqualified deferred compensation" under Section 409A
(whether under this Offer Letter, any other plan, program, payroll practice or
any equity grant) and is payable upon your 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-and­one-day period measured from the
date of your "separation from service," and (B) the date of your death (the
"Delay Period") and this Offer Letter 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 paragraph (whether they would have otherwise been payable in a single sum
or in installments in the absence of such delay) shall be paid or reimbursed to
you 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 Offer Letter shall be paid or provided in
accordance with the regularly scheduled payment dates specified for them herein.

23 Main Street | Holmdel, NJ 07733 | 732.528.2600 | www.vonage.com

--------------------------------------------------------------------------------

(iv)
For purposes of Section 409A, your right to receive any installment payments
pursuant to this Offer Letter shall be treated as a right to receive a series of
separate and distinct payments. Whenever a payment under this Offer Letter
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.

(v)
To the extent any reimbursement or in-kind payment provided pursuant to this
Offer Letter is deemed nonqualified deferred compensation subject to Section
409A then (i) all such expenses or other reimbursements as provided herein shall
be payable in accordance with the Company’s policies in effect from time to
time, but in any event shall be made on or prior to the last day of the taxable
year following the taxable year in which such expenses were incurred by you;
(ii) no such reimbursement or expenses eligible for reimbursement in any taxable
year shall in any way affect the expenses eligible for reimbursement in any
other taxable year; and (iii) the right to such reimbursement or in-kind
benefits shall not be subject to liquidation or exchanged for another benefit.

(vi)
No amounts payable to you by the Company or any of its subsidiaries or
affiliates under this Agreement or any other agreement that constitute
nonqualified deferred compensation subject to Section 409A shall be subject to
offset by any other amount, except as permitted under Section 409A.

(e)
Withholding. The Company may withhold any tax (or other governmental obligation)
that may result from the payments made and benefits provided to you under this
Offer Letter or require you to make other arrangements satisfactory to the
Company to enable it to satisfy all such withholding requirements.

(f)
Governing Law; Waiver of Jury Trial. All matters affecting this Offer Letter,
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. YOU AND THE COMPANY
HEREBY ACKNOWLEDGE AND AGREE THAT YOU AND THE COMPANY ARE HEREBY WAIVING ANY
RIGHTS TO TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM BROUGHT BY
EITHER YOU OR THE COMPANY AGAINST THE OTHER IN CONNECTION WITH ANY MATTER
WHATSOEVER ARISING OUT OF OR IN ANY WAY CONNECTED WITH THIS OFFER LETTER.
Disputes regarding your application for employment, employment, or termination
of employment will be subject to the attached Arbitration Agreement.

23 Main Street | Holmdel, NJ 07733 | 732.528.2600 | www.vonage.com

(g)
Remedies. In addition to all other legal and equitable remedies, the prevailing
party in any dispute that in any way relates to this Offer Letter or your
employment hereunder shall be entitled to recover his or its reasonable
attorneys’ fees and expenses incurred in connection with such dispute.

United States law requires all companies to verify an employee's authorization
to work in the United States. If you accept this offer, you will need to bring
certain documents with you on your Commencement Date which allow the Company to
verify your work authorization. Enclosed is an Employment Eligibility
Verification (form I-9). Please review the form and bring the appropriate
documents required for employment verification on your Commencement Date. You
will be asked to complete the form in the presence of a witness on your
Commencement Date.

If these terms are agreeable to you, please sign and date the Offer Letter in
the appropriate space at the bottom and return it to me by Friday March 31,

your future contributions.
