Mr. Jeffrey M. Snider
By electronic delivery
 
Dear Jeff:
 
I am pleased to provide you in this letter (this “Agreement”) with the AMENDED
AND RESTATED terms and conditions of your continued employment by Sonus
Networks, Inc. (the “Company”). The principal purpose of this Agreement is to
consolidate the changes that have been made to your employment terms since you
joined the Company.
 
1.            Position.  The Company agrees to continue to employ you as Chief
Administrative Officer, Senior Vice President, General Counsel and Corporate
Secretary, reporting to the President and Chief Executive Officer.  As the
Company’s organization evolves, in addition to performing duties and
responsibilities associated with the position of Chief Administrative Officer
you may be assigned other Executive duties and responsibilities as the Company
may determine.
 
2.            Nature of Relationship.  Subject to the severance and other
provisions of Section 7 below, your employment shall not be for any specified
period of time.  Employment at Sonus Networks, Inc. is “at will” and either you
or the Company may terminate the employment relationship at any time and for any
reason or no reason, subject to the provisions of Section 7 below.
 
3.            Compensation.  During your employment with the Company, you will
receive the following compensation:

(a)
Base Compensation.  Your base salary (“Base Salary”) will be at the annualized
rate of $350,000.00, less applicable state and federal withholdings, paid twice
monthly in accordance with the Company’s normal payroll practices.  The Company
will review your Base Salary on an annual basis and such base salary may be
adjusted at the discretion of the Compensation Committee of the Board of
Directors (the “Compensation Committee”); provided that you may elect to
terminate your employment for Good Reason under Section 8(b)(A) below if the
Compensation Committee reduces your Base Salary.

(b)
Target Bonus.  You will be eligible to participate in the Senior Management Cash
Incentive Plan (or its successor) during each year you are employed by the
Company with a target bonus of 75% of your then-current annual base salary
(“Target Bonus”).  Specific objectives for your Target Bonus will be agreed upon
with the Compensation Committee on or after January 1 with respect to an award
for such year.  Your annual Target Bonus will be paid as soon as practicable
following the Company’s public disclosure of its financial results for the
applicable bonus period.

(c)
Acquisition. In the event of an Acquisition (defined below), (i) 100% of all
unvested options granted to you to purchase the Company’s common stock shall
accelerate and all such options shall immediately become vested and exercisable
and (ii) 100% of all restricted shares granted to you shall accelerate and
become fully vested and any and all restrictions on such restricted shares shall
be terminated and any and all legends shall be removed.

 
4.            Benefits.  During your employment with the Company, you will be
entitled to the following benefits:

(a)
You will be entitled to vacation consistent with Company policy and limitations;

(b)
You will be entitled to participate as an employee of the Company in all benefit
plans and fringe benefits and perquisites generally provided to employees of the
Company in accordance with Company policy, currently including group health,
life and dental insurance, 401(k) program and equity incentive plans.  The
Company retains the right to change, add or cease any particular benefit for its
employees; and

(c)
The Company will reimburse you for all reasonable travel, business development,
meals, entertainment and other expenses incurred by you in connection with the
performance of your duties and obligations on behalf of the Company.  You will
comply with such limitations and reporting requirements with respect to expenses
as may be established by the Company from time to time and will promptly provide
all appropriate and requested documentation in connection with such expenses.

5.            Confidentiality.  The Company considers the protection of its
confidential information, proprietary materials and goodwill to be very
important.  Therefore, as a condition of your employment, you and the Company
became parties to a Noncompetition and Confidentiality Agreement as of the
commencement of your employment, and such agreement remains in full force and
effect.
 
6.            Indemnity.  As an executive of the Company, the Company provided
you with an Indemnity Agreement that you and the Company entered into as of the
commencement of your employment, and such agreement remains in full force and
effect. 
 
7.            Termination and Eligibility for Severance.  If your employment
with the Company is terminated by the Company without Cause (as defined below)
or you terminate your employment with the Company for Good Reason (as defined
below), the Company will provide you the following severance and related
post-termination benefits:

(a)
a lump sum payment equal to the sum of your then annual base salary and your
then target annual bonus, less applicable state and federal withholdings;
provided, however, if such termination occurs in contemplation of, upon or after
an Acquisition, the Company will provide you a single lump sum equal to (i)
eighteen (18) months of your then-current base salary and (ii) your then-current
target annual bonus at 150% of target, less applicable state and federal
withholdings;

(b)
continuation of payment of the Company’s share of medical, dental and vision
insurance premiums for you and your dependents for the twelve (12) month period
following the termination of your employment; provided, however, if such
termination occurs in contemplation of, upon or after an Acquisition, the
Company will provide you continuation of the Company’s share of medical, dental
and vision insurance premiums for you and your dependents for the eighteen (18)
month period following the termination of your employment; but provided further,
that if immediately prior to the termination of your employment you were
required to contribute towards the cost of such premiums as a condition of
receiving such insurance, you may be required to continue contributing towards
the cost of such premiums under the same terms and conditions as applied to you
and your dependents immediately prior to the termination of your employment in
order to receive such continued insurance coverage;

(c)
any allowable unreimbursed expenses and any accrued but unused vacation pay
owing to you at the time of termination;

(d)
any stock options granted to you by the Company to purchase the Company’s common
stock that are unvested as of the termination date and would vest during the
twelve (12) months following your termination will accelerate and immediately
vest and become exercisable upon termination, and your stock options that are or
become vested will remain outstanding and exercisable for the shorter of three
(3) years following your termination date or the original remaining life of the
options; and

(e)
any restricted shares granted to you by the Company that are unvested as of the
termination date will accelerate and immediately vest upon termination, and any
and all restrictions on such restricted shares shall be terminated and any and
all legends shall be removed so that the shares be and are freely marketable.

The Company’s provision of the benefits described in Sections 7(a), (b), (d) and
(e) above shall be contingent upon your execution of a release of all claims of
any kind or nature in favor of the Company in a form to be provided by the
Company (the “Release Agreement”), which Release Agreement must be delivered to
the Company within twenty-one (21) days following the termination of your
employment.  The lump sum payments described in Section 7(a) above shall be made
on the eighth (8th) day following the termination of your employment, after the
Company’s receipt of the executed Release Agreement and the expiration of any
revocation period described in the Release Agreement.  The Company shall have no
further obligation to you in the event your employment with the Company
terminates at any time, other than those obligations specifically set forth in
this Section 7.
 
The Company may terminate your employment at any time with or without Cause by
written notice to you specifying the date of termination.  You may terminate
your employment with or without Good Reason by providing written notice to the
Company at least thirty (30) days prior to the date of termination.  If you seek
to terminate your employment for Good Reason, the Company shall have ten
(10) business days following its receipt of written notice of termination to
cure the circumstance giving rise to Good Reason.  Upon a termination for Cause
by the Company or upon a termination without Good Reason, you will be entitled
to accrued but unpaid Base Salary and benefits through the date of termination
only.

9.           Tax Implications of Termination Payments.  Subject to this
Section 9, any payments or benefits required to be provided under Section 7
shall be provided only after the date of your “separation from service” with the
Company as defined under Section 409A of the U.S. Internal Revenue Code of 1986,
as amended, and the guidance issued thereunder (“Section 409A”). The following
rules shall apply with respect to distribution of the payments and benefits, if
any, to be provided to you under Section 7:
 
(a)
It is intended that each installment of the payments and benefits provided under
Section 7 shall be treated as a separate “payment” for purposes of
Section 409A.  Neither the Company nor you shall have the right to accelerate or
defer the delivery of any such payments or benefits except to the extent
specifically permitted or required by Section 409A.

(b)
If, as of the date of your “separation from service” with the Company, you are
not a “specified employee” (each within the meaning of Section 409A), then each
installment of the payments and benefits shall be made on the dates and terms
set forth in Section 7; and

(c)
If, as of the date of your “separation from service” with the Company, you are a
“specified employee” (each, for purposes of this Agreement, within the meaning
of Section 409A), then:

i.
Each installment of the payments and benefits due under Section 7 that, in
accordance with the dates and terms set forth herein, will in all circumstances,
regardless of when the separation from service occurs, be paid within the
short-term deferral period (as defined for the purposes of Section 409A) shall
be treated as a short-term deferral within the meaning of Treasury Regulation
Section 1.409A-1(b)(4) to the maximum extent permissible under Section 409A; and

ii.
Each installment of the payments and benefits due under Section 7 that is not
paid within the short-term deferral period or otherwise cannot be treated as a
short-term deferral within the meaning of Treasury Regulation
Section 1.409A-1(b)(4) and that would, absent this subsection, be paid within
the six-month period following your “separation from service” with the Company
shall not be paid until the date that is six months and one day after such
separation from service (or, if earlier, upon your death), with any such
installments that are required to be delayed being accumulated during the
six-month period and paid in a lump sum on the date that is six months and one
day following your separation from service and any subsequent installments, if
any, being paid in accordance with the dates and terms set forth herein;
provided, however, that the preceding provisions of this sentence shall not
apply to any installment of payments if and to the maximum extent that that such
installment is deemed to be paid under a separation pay plan that does not
provide for a deferral of compensation by reason of the application of Treasury
Regulation 1.409A-1(b)(9)(iii) (relating to separation pay upon an involuntary
separation from service).  Any installments that qualify for the exception under
Treasury Regulation Section 1.409A-1(b)(9)(iii) must be paid no later than the
last day of the second taxable year following the taxable year in which your
separation from service occurs.

 
10.           Section 409A of the Code.  This Agreement is intended to comply
with the provisions of Section 409A and this Agreement shall, to the extent
practicable, be construed in accordance therewith.  Terms used in this Agreement
shall have the meanings given such terms under Section 409A if and to the extent
required in order to comply with Section 409A.  Notwithstanding the foregoing,
to the extent that this Agreement or any payment or benefit hereunder shall be
deemed not to comply with Section 409A, then neither the Company, the Board of
Directors nor its or their designees or agents shall be liable to you or any
other person for any actions, decisions or determinations made in good faith.
 
11.            Other Agreements.  You represent and warrant that, in the
performance of your duties with the Company, you will not utilize or disclose
any confidential information in breach of an agreement with a previous employer
or any other party.
 
12.            Assignment.  This Agreement is personal in nature and neither of
the parties hereto shall, without the written consent of the other, assign or
otherwise transfer this Agreement or its obligations, duties and rights under
this Agreement; provided, however, that in the event of the merger,
consolidation, transfer or sale of all or substantially all of the assets of the
Company, this Agreement shall, subject to the provisions hereof, be binding upon
and inure to the benefit of such successor and such successor shall discharge
and perform all of the promises, covenants, duties and obligations of the
Company hereunder.
 
13.            General.
 
(a)
Entire Agreement; Modification.  This Agreement contains the entire agreement of
the parties relating to the subject matter hereof, and the parties hereto have
made no agreements, representations or warranties relating to the subject matter

supersedes any and all prior agreements, written or oral, between you and the
Company.  No modification of this Agreement shall be valid unless made in
writing and signed by the parties hereto.

(b)
Severable Provisions.  The provisions of this Agreement are severable and if any
one or more provisions may be determined to be illegal or otherwise
unenforceable, in whole or in part, the remaining provisions of this Agreement
shall nevertheless be binding and enforceable.  Notwithstanding the foregoing,
if there are any conflicts between the terms of this Agreement and the terms of
any Company equity incentive plan document referred to in this Agreement, then
the terms of this Agreement shall govern and control.  Except as modified
hereby, this Agreement shall remain unmodified and in full force and effect.

(c)
Governing Law.  This Agreement shall be governed by and interpreted in
accordance with the laws of the Commonwealth of Massachusetts, without regard to
the conflict of laws provisions hereof.

Arbitration.

i.
Any controversy, dispute or claim arising out of or relating to this Agreement
or the breach hereof which cannot be settled by mutual agreement will be finally
settled by binding arbitration in the commonwealth of Massachusetts, under the
jurisdiction of the American Arbitration Association or other mutually agreeable
alternative arbitration dispute resolution service, before a single arbitrator
appointed in accordance with the arbitration rules of the American Arbitration
Association or other selected service, modified only as herein expressly
provided.  The arbitrator may enter a default decision against any party who
fails to participate in the arbitration proceedings.

The decision of the arbitrator on the points in dispute will be final,
non-appealable and binding, and judgment on the award may be entered in any

Section 13(d) will be grounds for dismissal of any court action commenced by
either party with respect to this Agreement, other than post-arbitration actions
seeking to enforce an arbitration award or actions seeking an injunction or
temporary restraining order.  In the event that any court determines that this
arbitration procedure is not binding, or otherwise allows any litigation
regarding a dispute, claim, or controversy covered by this Agreement to proceed,
the parties hereto hereby waive, to the maximum extent allowed by law, any and
all right to a trial by jury in or with respect to such litigation.

v.
The parties will keep confidential, and will not disclose to any person, except

controversy hereunder, the referral of any such controversy to arbitration or
the status or resolution thereof
