Dear Mike:
I am pleased to provide you in this letter (the “Agreement”) to confirm the
terms and conditions of your recent promotion with Sonus Networks, Inc. (the
“Company”), effective as of the date of your signed acceptance.
1.    Position. You will be employed as Senior Vice President of Worldwide Sales
and Marketing, reporting to the President and Chief Executive Officer (the
“CEO”). As the Company’s organization evolves, in addition to performing duties
and responsibilities currently associated with these positions, you may be
assigned other executive duties and responsibilities as the Company may
determine. As a full-time employee of the Company, you will be expected to
devote your full business time and energies to the business and affairs of the
Company.
2.    Promotion Date/Nature of Relationship. Your promotion was effective as of
the date of your signed acceptance (the “Promotion Date”). Employment by the
Company 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 remain at the
annualized rate of $320,000, 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 (as defined below) if the Compensation
Committee reduces your Base Salary without your consent.
(b)    Target Bonus. Commencing with the 2015 fiscal year, 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 CEO on or after January 1 of each
year with respect to an award for such year. Your annual bonus, if earned, shall
be paid as soon as practicable following the Company’s public disclosure of its
financial results for the applicable bonus year, but in no event later than
April 15 of each such subsequent year. For 2014, if your Target Bonus would have
been greater than

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

your current variable compensation, the Company will pay you an amount equal to
the difference, such payment to be made at the same time other executive annual
bonuses are paid out.
(c)    Acquisition. In the event of an Acquisition (as defined below), (i) 50%
of all unvested options granted to you to purchase the Company’s common stock
will vest immediately upon the date of the Acquisition, and the remaining
unvested options granted to you will continue to vest according to their terms;
and (ii) 50% of all restricted shares granted to you will vest immediately upon
the date of Acquisition and the remaining unvested restricted shares will
continue to vest according to their terms.
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, fringe benefits and perquisites generally provided to employees
of the Company in accordance with Company policy as in effect from time to time.

change, add or cease any particular benefit for its employees.
(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. You are,
and will remain, subject to the terms of the Confidentiality, Non-Competition
and Assignment of Inventions Agreement (“Confidentiality Agreement”) that you
signed previously in connection with your employment with the Company.
6.    Indemnity. As an executive of the Company, the Company will provide you
with an Indemnity Agreement, a copy of which has been sent with this Agreement.
7.    Termination and Eligibility for Severance. Upon any termination of your
employment (the “Date of Termination”), you will be paid (i) any and all earned
and unpaid portion of your Base Salary through the Date of Termination; (ii) any
accrued but unused vacation pay owed to you in accordance with Company practices
up to and including the Date of Termination; and (iii) any allowable and
unreimbursed business expense incurred through the Date of Termination that are
supported by appropriate documentation in accordance with the Company’s
policies. Hereafter, items (i) through (iii) in this Section 7 are referred to
as “Accrued Benefits.” If the Company terminates your employment for Cause (as
defined below) or you terminate your employment without Good Reason (as defined
below), you will be entitled to receive only the Accrued Benefits.
If the Company terminates your employment without Cause, your employment
terminates due to your death or Disability (as defined below), or you terminate
your employment with Good Reason, then subject to the additional conditions of
this Agreement, the Company will provide you (or your estate or successors or
assigns, as the case may be) with the following severance and related
post-termination benefits, to which you otherwise would not be entitled:

2

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

(a)    The Company will pay you a lump sum payment equal to (i) twelve (12)
months of your then-current Base Salary payable at the time of termination and
(ii) 100% of your then-current Target Bonus; provided, however, that if your
termination occurs in contemplation of, upon or after an Acquisition, the
Company will pay you a lump sum payment equal to (y) eighteen (18) months of
your then-current Base Salary payable at the time of termination and (z) 150% of
your then-current Target Bonus.
(b)    The Company will continue to pay 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, that if
your termination occurs in contemplation of, upon or after an Acquisition, the
Company will continue to pay 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. In any case, 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 in order to receive such continued
insurance coverage.
(c)    Any options granted to you by the Company to purchase the Company’s
common stock that are unvested as of the Date of Termination and would have
vested in the twelve (12) months following your termination will accelerate and
immediately vest and become exercisable upon termination, and your options that
are or become vested will remain outstanding and exercisable for the shorter of
three (3) years following your Date of Termination or the original remaining
life of such options; provided that if your termination occurs in contemplation
of, upon or after an Acquisition, then all unvested options at that time will
accelerate and immediately vest and become exercisable.
(d)    Any restricted shares granted to you by the Company that are unvested as
of the Date of Termination and that would vest during the twelve (12) months
following your termination will accelerate and immediately vest upon
termination, and such shares will be freely marketable; provided that if your
termination occurs in contemplation of, upon or after an Acquisition, then all
of your unvested restricted shares at that time will fully accelerate,
immediately vest upon termination and be freely marketable.
(e)    The Company’s provision of the benefits described in Section 7(a), (b),
(c) and (d) above shall be contingent upon (y) your execution and delivery 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”), and on such Release
Agreement becoming effective as a matter of law; and (z) your compliance and
continuing compliance with the covenants in your Confidentiality Agreement. The
payment described in Section 7(a) above shall be made promptly following 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.
(f)    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

provide the Company with written notification specifying the basis for your
claim of Good Reason, and the Company shall have ten (10) days following its

only after the date of your “separation from service”

4

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

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 to the Company that you are
not bound by any agreement with a previous employer or other party which you
would in any way violate by accepting employment with the Company or performing
your duties as an employee of the Company. You further

you will not utilize or disclose any confidential information in breach of an
agreement with a previous employer or any other party.
