MACOM TECHNOLOGY SOLUTIONS HOLDINGS, INC.
CHANGE IN CONTROL PLAN
Effective as of October 3, 2014
Amended and Restated on February 11, 2017

    The Plan established by MACOM Technology Solutions Holdings, Inc., a
Delaware corporation, was originally effective as of the Effective Date and was
amended and restated effective as of the date set forth above. The purpose of
the Plan is to secure for the benefit of the Company the services of the
participating Employees, without concern for whether such Employees might be
hindered in discharging their duties by the personal uncertainties and risks
associated with a Change in Control, by affording such Employees the opportunity
to protect and share in the value they have helped create and offering income
protection to such Employees in the event their employment terminates
involuntarily without Cause or for Good Reason, in either case, in connection
with a Change in Control as provided for in the Plan. All capitalized terms in
the Plan have the meaning set forth in Section 2 or elsewhere in the Plan.
1.
Applicability of Plan.

1.1    Applicability of Plan. Subject to the terms and conditions of the Plan,
the benefits provided by the Plan shall be available to those Employees who, on
or after the Effective Date, are designated as a Participant and who sign and
return to the Company a Notice of Participation pursuant to Section 3.
1.2    Contractual Right to Benefits. The Plan and the Notice of Participation
establish and vest in each Participant a contractual right to the benefits to
which he or she is entitled pursuant to the terms and conditions thereof,
enforceable by the Participant against the Company.
2.
Definitions and Construction.

Whenever capitalized in the Plan, the following terms shall have the meanings
set forth below.
2.1    Administrator. “Administrator” shall mean the Board; provided, that the
Board (or its delegate) may delegate some or all of its authority under the Plan
to its Compensation Committee or and such committee shall be the Administrator
for purposes of the Plan; notwithstanding the foregoing, following a Change in
Control the Plan shall be administered by the Board or, if the Company is not
the surviving corporation, the board of directors of the surviving corporation
or acquirer, as applicable.
2.2    Base Salary. “Base Salary” shall mean an amount equal to the
Participant’s gross monthly base salary, as in effect immediately preceding the
Change in Control (or as increased after the date of such Change in Control).
2.3    Board. “Board” shall mean the Board of Directors of the Company.
2.4    Cause. “Cause” shall mean (a) an act of fraud by the Participant in
connection with the Participant’s responsibilities as an Employee; (b) the
Participant’s conviction of, or plea of nolo contendere to, a felony, or
commission of an act of moral turpitude; (c) the Participant’s willful and gross
misconduct that results, or is reasonably likely to result, in material adverse
harm to the Company; or (d) the Participant’s willful and material failure to
substantially perform the duties and responsibilities of the Participant’s
position that Participant does not remedy within the thirty (30)-day period
after a written demand for substantial performance is delivered to the
Participant by the Company, which demand specifically identifies the manner in
which the Company believes that the Participant has not substantially performed
such duties or responsibilities. No act, or failure to act, on the Participant’s
part shall be deemed “willful” for purposes of the Plan unless committed or
omitted by the Participant in bad faith and without reasonable belief that the
Participant’s act or failure to act was in, or not opposed to, the best interest
of the Company.
2.5    Change in Control. “Change in Control” shall mean the occurrence of any
of the following events:
(a)    An acquisition by any individual, entity or group (within the meaning of
Section 13(d)(3) or 14(d)(2) of the Exchange Act) (a “Person”) of beneficial
ownership (within the meaning of Rule 13d-3 promulgated under the Exchange Act)
of 50% or more of either (i) the then outstanding shares of common stock of the
Company (the “Outstanding Company Common Stock”) or (ii) the combined voting
power of the then outstanding voting securities of the Company entitled to vote
generally in the election of directors (the “Outstanding Company Voting
Securities”); excluding, however, the following acquisitions of Outstanding
Company Common Stock and/or Outstanding Company Voting Securities: (1) any
acquisition directly from the Company, other than an acquisition by virtue of
the exercise of a conversion privilege unless the security being so converted
was itself acquired directly from the Company, (2) any acquisition by the
Company or a wholly-owned subsidiary of the Company, (3) any acquisition by any
employee benefit plan (or related trust) sponsored or maintained by the Company,
or (4) any acquisition by any Person pursuant to a transaction that is described
in clauses (i), (ii) and (iii) of Section 2.5(c); or

(b)    A change in the composition of the Board such that the individuals who,
as of the Effective Date, constitute the Board (the “Incumbent Board”) cease for
any reason to constitute at least a majority of the Board; provided, however,
that any individual who becomes a member of the Board subsequent to the
Effective Date whose election, or nomination for election by the Company’s
stockholders, was approved by a vote of at least a majority of those individuals
who are members of the Board and who were also members of the Incumbent Board
(or deemed to be such pursuant to this proviso) shall be considered as though
such individual was a member of the Incumbent Board; but, provided, further,
that any such individual whose initial assumption of office occurs as a result
of or in connection with an actual or threatened election contest with respect
to the removal of directors or other actual or threatened solicitation of
proxies or consents by or on behalf of a Person other than the Board shall not
be considered a member of the Incumbent Board; or

(c)    The consummation of a reorganization, merger or consolidation (any of the
foregoing, a “Business Combination”) or sale or other disposition of all or
substantially all of the assets of the Company; excluding, however, such a
Business Combination pursuant to which:

(i)    all or substantially all of the individuals and entities who are the
beneficial owners, respectively, of the Outstanding Company Common Stock and
Outstanding Company Voting Securities immediately prior to such Business
Combination shall beneficially own, directly or indirectly, more than 50% of,
respectively, the outstanding shares of common stock, and the combined voting
power of the then outstanding voting securities entitled to vote generally in
the election of directors, as the case may be, of the corporation resulting from
such Business Combination (including, without limitation, a corporation that as
a result of such transaction owns the Company or all or substantially all of the
Company’s assets) in substantially the same proportions as their ownership,
immediately prior to such Business Combination, of the Outstanding Company
Common Stock and Outstanding Company Voting Securities, as the case may be,

(ii)    no Person (other than any employee benefit plan (or related trust)
sponsored or maintained by the Company or any entity controlled by the Company
or such corporation resulting from such Business Combination) shall beneficially
own, directly or indirectly, 50% or more of, respectively, the outstanding
shares of common stock of the corporation resulting from such Business
Combination or the combined voting power of the outstanding voting securities of
such corporation entitled to vote generally in the election of directors, except
to the extent that such ownership existed with respect to the Company prior to
the Business Combination, and

(iii)    at least a majority of the members of the board of directors of the
corporation resulting from such Business Combination shall have been members of
the Incumbent Board at the time of the execution of the initial agreement, or of
the action of the Board, providing for such Business Combination.

Notwithstanding the foregoing, in any case where the occurrence of a Change in
Control could affect the vesting of or payment of any amount subject to the
requirements of Code Section 409A, to the extent required to comply with Code
Section 409A, the term “Change of Control” shall mean an occurrence that both
(i) satisfies the requirements set forth above in this definition and (ii) is a
“change in control event” as that term is defined in the regulations under Code
Section 409A. If all or a portion of any amount payable under the Plan
constitutes deferred compensation under Code Section 409A and such amount (or
portion thereof) is to be settled, distributed or paid on an accelerated basis
due to a Change in Control that is not a “change in control event” under Code
Section 409A, if such settlement, distribution or payment would result in
additional tax under Code Section 409A, such amount (or portion thereof) shall
vest at the time of the Change in Control (provided such accelerated vesting
will not result in additional tax under Section 409A), but settlement,
distribution or payment, as the case may be, shall only be accelerated to the
maximum extent possible without resulting in a violation of Code Section 409A.
For the avoidance of doubt, in no event shall the foregoing two sentences act so
as to reduce the aggregate amounts otherwise payable to a Participant pursuant
to this Plan.

2.6    Code. “Code” shall mean the Internal Revenue Code of 1986, as amended.
2.7    Company. “Company” shall mean MACOM Technology Solutions Holdings, Inc.,
any successor entities as provided in Section 8.1 and any Section 409A
Affiliates as defined in Section 10.2(b).
2.8    Disability. “Disability” shall mean a mental or physical impairment of
the Participant that is expected to result in death or that has lasted or is
expected to last for a continuous period of 12 months or more and that causes
the Participant to be unable to perform his or her material duties for the
Company and to be engaged in any substantial gainful activity, in each case as
determined by the Administrator, whose determination shall be conclusive and
binding.
2.9    Effective Date. “Effective Date” for purposes of the Plan shall mean the
October 3, 2014.
2.10    Employee. “Employee” shall mean an employee of the Company.
2.11    ERISA. “ERISA” shall mean the Employee Retirement Income Security Act of
1974, as amended.
2.12    Exchange Act. “Exchange Act” shall mean the Securities Exchange Act of
1934, as amended.

without the Participant’s express written consent and that the Company fails to
cure within the time frame specified in Section 12.3: (a) the material reduction
of the Participant’s authority, duties or responsibilities, or assignment to the
Participant of duties, in either case, which results in a material diminution of
the Participant’s authority, duties or responsibilities as compared to those in
effect immediately prior to a Change in Control; (b) a reduction in the
Participant’s Base Salary; (c) a reduction in the Participant’s “target” bonus
opportunity, “target” long-term incentive opportunity or “target” equity
incentive opportunity, in each case, as determined by taking into account each
opportunity in effect immediately prior to a Change in Control (or as increased
after the date of a Change in Control); (d) any action or inaction by the
Company that constitutes a material breach by the Company of the Plan; or (e) a
change in the Participant’s geographic work location of over 50 miles from the
Participant’s geographic work location immediately prior to such change, except
for required travel in furtherance of the Company’s business to the extent
consistent with the Participant’s duties.
2.14    Notice of Participation. “Notice of Participation” shall mean an
individualized written notice of participation in the Plan from an authorized
officer of the Company issued to an individual approved for Plan participation
by the Administrator.
2.15    Participant. “Participant” shall mean each Employee designated by the
Administrator as a Participant and who signs and returns to the Company a Notice
of Participation indicating that such Employee agrees to be a Participant.
2.16    Plan. “Plan” shall mean the MACOM Technology Solutions Holdings, Inc.

hereto.
2.17    Protected Period. “Protected Period” shall mean the period beginning
three months immediately prior to a Change in Control and ending at the time

2.1    Qualifying Termination. “Qualifying Termination” shall mean, with respect
to a Participant, a termination of the Participant’s employment by the Company
involuntarily without Cause or by the Participant for Good Reason (i) during the
Protected Period prior to a Change in Control where such termination without
Cause or such changes comprising Good Reason, as the case may be, are measures
taken in connection with a Change in Control or (ii) during the Protected Period
following a Change in Control.
2.2    Release. “Release” shall mean a separation and release agreement
containing a general waiver and release of claims, and a mutual nondisparagement
provision, in substantially the same form as provided to the Participant with
the Notice of Participation.
2.3    Severance Payments. “Severance Payments” shall mean the severance
compensation and benefits as provided in Section 4.
3.
Eligibility.

3.1    Release of Claims. As a condition of receiving any payments or benefits
under the Plan, a Participant must sign (and not revoke, if applicable) a
Release, which Release must become effective (i.e., the Participant must sign
the Release and any revocation period specified therein must have expired
without the Participant revoking the Release) no later than 60 days following
the Participant’s termination of employment (or, if earlier, by the date
specified in the Release). If the Release does not become effective by the
deadline specified in the immediately preceding sentence, then no such payments
or benefits shall be provided to the Participant.
3.2    Participation in Plan. Each Employee who is designated by the
Administrator as a Participant and who signs and returns to the Company a Notice
of Participation by the date set forth therein shall be a Participant in the
Plan. A Participant shall cease to be a Participant in the Plan upon ceasing to
be an Employee; provided, however, that once a Participant has become entitled
to payments and benefits hereunder, he or she shall remain a Participant in the
Plan until the full amount of the payments and benefits has been delivered to
the Participant.
4.    Severance Payments.
4.1    Cash Severance Payments. If a Participant experiences a Qualifying
Termination then, subject to the terms and conditions of the Plan, including
Sections 3.1, 5 and 6, the Participant shall be entitled to receive the cash
payment described in the Participant’s Notice of Participation.
4.2    Treatment of Equity Awards. Notwithstanding any provision in the
instrument evidencing an equity award and except as otherwise provided in
Section 4.2(d):
(a)    If a Participant experiences a Qualifying Termination then, subject to
the terms and conditions of the Plan, including Sections 3.1, 5 and 6, all then
outstanding equity-based awards that become exercisable, vested or payable based
solely on continued service granted to the Participant under any applicable
equity compensation plans of the Company as in effect on the date of the Change
in Control, whether granted before or after the Effective Date, shall become
fully vested and exercisable or payable as of the effective date of the
Participant’s termination of employment; provided, that if an award provides
deferred compensation subject to Code Section 409A, such award will be paid at
the same time and in the same form as it would have been paid had no Change in
Control occurred.
(b)    In the event of a Change in Control, all outstanding equity-based awards
that are eligible to become exercisable, vested and/or payable (or that provide
for accelerated vesting or payment) upon the attainment of specified performance
goals granted to the Participant under any applicable equity compensation plans
of the Company as in effect on the date of the Change in Control, whether
granted before or after the Effective Date, shall be deemed earned at maximum
levels of performance as of immediately prior to the Change in Control, such
equity-based awards to become exercisable, vested and/or payable upon completion
of the later of (i) any originally applicable performance period and (ii) any
applicable service-based vesting period relating to such award, subject to the
Participant’s continued employment through the applicable vesting dates;
provided, that, subject to Sections 3.1, 5 and 6, such equity-based awards shall
immediately become fully exercisable, vested and/or payable if, the Participant
experiences a Qualifying Termination; provided further, that if an award
provides deferred compensation subject to Code Section 409A, such award will be
paid at the same time and in the same form as it would have been paid had no
Change in Control occurred.
(c)    For the avoidance of doubt, any unvested equity-based awards shall cease
vesting immediately on the date of Participant’s termination of employment, but
shall not terminate until the date on which it is determined whether the
Participant is eligible to receive accelerated vesting under this Section 4.2.
(d)    Notwithstanding the foregoing or anything herein to the contrary, (i) any
equity-based award with terms that are more favorable to the Participant in the
event of a Change in Control or termination of the Participant’s employment than
the terms set forth in Section 4.2(a) or ‎4.2(b) above, as applicable, shall
continue to be subject to such terms, and (ii) if the instrument evidencing an
equity award expressly refers to this Plan and overrides and supersedes its
terms, such express exclusion shall be controlling as to such applicable award.
4.3    Method of Payment. Any cash Severance Payment to which a Participant
becomes entitled pursuant to Section 4.1 shall be paid to the Participant in a
lump sum within 10 days of the effective date of the Participant’s Release;
provided, that, to the extent any cash Severance Payment is subject to Code
Section 409A, such cash severance payment will be paid at the same time and in
the same form as it would have been paid had no Change in Control occurred to
the extent necessary to avoid adverse tax consequences under Code Section 409A;
provided, further that if the consideration period for the Release spans two
calendar years, any cash Severance Payment that is subject to Code Section 409A
will in all events be paid in the second calendar year. If a Participant dies
after becoming eligible for a cash Severance Payment and executing a Release but
before payment of the cash Severance Payment, the cash Severance Payment will be
paid to the Participant’s estate in a lump sum within 60 days of the
Participant’s death, provided that the Release becomes effective prior to such
date. If a Participant dies after becoming eligible for a cash Severance Payment
but before executing a Release, the personal representative of the Participant’s
estate shall be permitted to sign a Release on the Participant’s (and the
Participant’s estate’s) behalf. All payments and benefits under the Plan will be
net of amounts withheld with respect to taxes, offsets or other obligations.
4.4    Voluntary Resignation; Termination for Cause. If (a) the Participant’s
employment terminates by reason of the Participant’s voluntary resignation after
a Change in Control other than for Good Reason, or (b) the Company terminates
the Participant for Cause, then the Participant shall not be entitled to receive
any payments or benefits under the Plan and shall be entitled only to those
payments and benefits (if any) as may be available under the Company’s then
existing benefit plans and policies at the time of such termination.
4.5    Disability; Death. If the Participant’s employment terminates by reason
of the Participant’s death, or in the event the Company terminates the
Participant’s employment following his or her Disability, the Participant shall
not be entitled to receive any payments or benefits under the Plan and shall be
entitled only to those payments and benefits (if any) as may be available under
the Company’s then existing benefits plans and policies at the time of such
termination.
5.
Golden Parachute Excise Tax.

5.1    Gross-Up Payment. In the event that a Participant becomes entitled to
receive any payment or benefit under the Plan, either alone or when aggregated
with any other payments or benefits received (or to be received) by the
Participant from the Company (each, a “Payment” and, collectively, the “Total
Payments”), and any of the Total Payments will be subject to any excise tax
pursuant to Section 4999 of the Code or any similar or successor provision (the
“Excise Tax”), the Company shall make an additional lump-sum cash payment to the
Participant (a “Gross-Up Payment”) in an amount such that after payment by the
Participant of all taxes (including any interest or penalties imposed with
respect to such taxes), including, without limitation, any income and employment
taxes (and any interest and penalties imposed with respect thereto) and the
Excise Tax imposed upon the Gross-Up Payment, the Participant retains an amount
of the Gross-Up Payment equal to the Excise Tax imposed upon the Total Payments.
5.2    Timing of Payment. A Gross-Up Payment, if any, shall be made by the
Company to the Participant on or within 10 business days of the date that the
related Excise Tax on the Total Payments is required to be remitted to the
relevant taxing authorities. Notwithstanding anything to the contrary in this
Section 5, in no event will a Gross-Up Payment be made on a day that is later
than the last day of the Participant’s taxable year that immediately follows the
Participant’s taxable year in which the related Excise Tax on the Total Payments
is remitted to the relevant taxing authorities.
5.3    Determination. Unless the Company and the Participant otherwise agree in
writing, any determination required under this Section 5 or the Participant’s
Notice of Participation shall be made in writing by an independent accounting
firm appointed by the Company (the “Accountants”), whose determination shall be
conclusive and binding upon the Participant and the Company. For purposes of
making the calculations required by Section 5, the Accountants may make
reasonable assumptions and approximations concerning applicable taxes and may
rely on reasonable, good faith interpretations concerning the application of
Code Sections 280G and 4999. The Company and the Participant shall furnish to
the Accountants such information and documents as the Accountants may reasonably
request in order to make a determination under this Section 5. The Company shall
bear all costs the Accountants may reasonably incur in connection with any
calculations pursuant to this Section 5.
6.
Forfeiture of Severance Payments.

The Severance Payments are conditioned on a Participant’s execution of the
Release and compliance with any non-competition or non-solicitation agreement
between Participant and the Company or any confidentiality or invention
assignment agreement entered into between Participant and the Company, in each
case, prior to the Change in Control (collectively, the “Participant’s
Contractual Obligations”). Notwithstanding any other provision of the Plan to
the contrary, if the Company reasonably determines based on demonstrable and
substantial evidence that the Participant has materially breached any of the
Participant’s Contractual Obligations, the Company may suspend any payments due
(but not yet paid) to the Participant under the Plan; provided that the Company
has provided Participant written notice of its intention to suspend such
payments, which notice specifically describes the facts and circumstances
supporting the Company’s belief that Participant has breached the Participant’s
Contractual Obligations, and an opportunity of not less than ten business days
in which to respond to the written notice. Should it be determined through final
adjudication that Participant materially has breached any of the Participant’s
Contractual Obligations, then Participant shall be required to repay to the
Company an amount equal to the economic value of all payments and benefits
already paid or provided to the Participant under the Plan and the Participant
(including the Participant’s estate and successors) shall forfeit all other
entitlements under the Plan. Additional forfeiture provisions may apply under
the Plan or other agreements between the Participant and the Company, and any
such forfeiture provisions shall remain in full force and effect. On the other
hand, should it be determined through final adjudication that Participant has
not materially breached any of the Participant’s Contractual Obligations, then
the Participant shall be entitled to recover all amounts withheld or suspended
by the Company pursuant to this Section 6, in addition to interest on such
amounts at the rate of six percent (6%) per year (compounded) beginning on the
date such amounts would have been paid, absent such withholding or suspension,
and the reasonable attorneys’ fees and costs incurred by Participant in such
action, as provided under Section 11.4.
7.
Employment Status; Withholding.

7.1    Employment Status. The Plan does not constitute a contract of employment
or impose on any Participant or the Company any obligation to retain the
Participant as an Employee, to change the status of the Participant’s
employment, or to change the Company’s policies regarding termination of
employment. Each Participant’s employment with the Company is and shall continue
to be at-will.
7.2    Tax Withholdings. All payments and benefits made or provided pursuant to
the Plan shall be subject to applicable payroll and income tax withholding and
other legally required deductions; provided that the amount so withheld shall
not exceed the minimum amount required to be withheld by applicable law.
8.
Successors to Company and Participants.

8.1    Company’s Successors. Any successor to the Company (whether direct or
indirect and whether by purchase, lease, merger, consolidation, liquidation or
otherwise) or acquirer of all or substantially all of the Company’s business
and/or assets shall assume the obligations under the Plan and agree expressly to
perform the obligations under the Plan. For all purposes under the Plan, the
term “Company” shall include any successor to the Company or acquirer of the
Company’s business and/or assets pursuant to the terms of an agreement between
the Company and such successor or acquirer or by operation of law.
8.2    Participant’s Successors. All rights of the Participant hereunder shall
inure to the benefit of, and be enforceable by, the Participant’s personal or
legal representatives, executors, administrators, successors, heirs,
distributees, devisees and legatees.
9.
Duration, Amendment and Termination.

9.1    Term/Duration. The Term of this Plan (the “Term”) commenced on the
Effective Date and shall continue in effect through June 30, 2019; provided,
however, that commencing on July 1, 2019 and each July 1st thereafter, the Term
shall automatically be extended for one additional year unless, not later than
three months prior to the expiration of the Term (i.e., on or before April 1),
the Administrator shall have given notice not to extend the Term.
Notwithstanding the foregoing, if a Change in Control occurs during the Term,
then the Plan shall terminate upon the date that all obligations of the Company
hereunder have been satisfied.
9.2    Amendment and Termination. The Administrator shall have the discretionary
authority to amend the Plan in any respect, including as to the removal or
addition of Participants, or to terminate or suspend the Plan, by resolution
adopted by a majority of the Board or its Compensation Committee, as applicable;
provided, however, that with respect to any Participant that has been designated
by the Administrator as a Participant and has signed and returned to the Company
a Notice of Participation indicating that such Employee has agreed to be a
Participant, no such amendment, termination or suspension of the Plan shall be
effective as to such Participant unless (a) the Participant would not be
adversely affected in any way by such amendment, termination or suspension or
(b) the Participant consents in writing to such amendment, termination or
suspension. Following a Change in Control, the Administrator shall not be
entitled to, and shall be prohibited from, amending or terminating the Plan,
other than such amendment or termination taking effect prospectively after the
end of the Protected Period; provided that any such amendment or termination
will not adversely affect any benefit provided to any Participant under this
Plan.
10.
Administration.

10.1    Power and Authority. The Administrator has all power and authority
necessary or convenient to administer the Plan, including, but not limited to,
the exclusive authority and discretion: (a) to construe and interpret the Plan;
(b) to decide all questions of eligibility for and the amount of benefits under
the Plan; (c) to prescribe procedures to be followed and the forms to be used by
the Participants pursuant to the Plan; and (d) to request and receive from all
Participants such information as the Administrator determines is necessary for
the proper administration of the Plan.
10.2    Code Section 409A. The provisions for Code Section 409A shall be applied
as follows:
(a)    The Company makes no representations or warranties to any Employee with
respect to any tax, economic or legal consequences of the Plan or any payments
to any Participant hereunder, including, without limitation, under Code
Section 409A, and no provision of the Plan shall be interpreted or construed to
transfer any liability for failure to comply with Code Section 409A or any other
applicable legal requirements from the Participant or other individual to the
Company or any of its affiliates. Each Participant, by executing a Notice of
Participation, shall be deemed to have waived any claim against the Company and
its affiliates with respect to any such tax, economic or legal consequences.
However, the payments and benefits provided under the Plan are not intended to
constitute deferred compensation that is subject to the requirements of Code
Section 409A. Rather, the Company intends that the Plan and the payments and
other benefits provided hereunder be exempt from the requirements of Code
Section 409A, whether pursuant to the short-term deferral exception described in
Treas. Reg. § 1.409A‑1(b)(4), the involuntary separation pay plan exception
described in Treas. Reg. § 1.409A‑1(b)(9)(iii) or otherwise. Notwithstanding any
provision of the Plan to the contrary, the Plan shall be interpreted, operated
and administered in a manner consistent with such intention;
(b)    Without limiting the generality of the foregoing, and notwithstanding any
other provision of the Plan to the contrary, all references herein to a
Participant’s termination of employment are intended to mean the Participant’s
“separation from service” from the Company and its Section 409A Affiliates
within the meaning of Code Section 409A. “Section 409A Affiliates” means each
entity that is required to be included in the Company’s controlled group of
corporations within the meaning of Code Section 414(b) or (c); provided,
however, that the phrase “at least 50 percent” shall be used in place of the
phrase “at least 80 percent” each place it appears therein or in the regulations
thereunder;
(c)    If the Company determines that any of the payments or benefits under the
Plan constitute “deferred compensation” under Code Section 409A and the
Participant is, on the date of his or her termination of employment, a
“specified employee” of the Company, as such term is defined in Code Section
409A(a)(2)(B)(i), then, solely to the extent necessary to avoid the incurrence
of the adverse personal tax consequences under Code Section 409A, the timing of
the payment of such pay or benefits shall be delayed until the earlier to occur
of the date that is six months and one day after the Participant’s termination
of employment or the date of the Participant’s death after the Participant’s
termination of employment;
(d)    To the extent that any reimbursement under the Plan is deemed to
constitute taxable compensation to a Participant, such reimbursement will be
made no later than December 31 of the year following the year in which the
expense was incurred. The amount of any such reimbursement provided in one year
shall not affect the expenses eligible for reimbursement in any subsequent year,
and the Participant’s right to such reimbursement will not be subject to
liquidation or exchange for any other benefit; and
(e)    If any payments or benefits under the Plan would violate the terms of
Section 16(b) of the Exchange Act or other federal securities laws, or any other
applicable law, then the payment or the provision of such payments or benefits
shall be delayed until the earliest date on which making such payment or
providing such benefit would not violate such law.
11.
Claims Process.

11.1    Claim for Benefits. A Participant (or any individual authorized by such
Participant) has the right under ERISA and the Plan to file a written claim for
benefits. To file a claim, the Participant must send the written claim to the
Company’s Vice President of Human Resources. If such claim is denied in whole or
in part, the Participant shall receive written notice of the decision of the
Company’s Vice President of Human Resources within 90 days after the claim is
received. Such written notice shall include the following information:
(a) specific reasons for the denial; (b) specific reference to pertinent Plan
provisions on which the denial is based; (c) a description of any additional
material or information necessary for the perfection of the claim and an
explanation of why it is needed; and (d) steps to be taken if the Participant
wishes to appeal the denial of the claim, including a statement of the
Participant’s right to bring a civil action under Section 502(a) of ERISA upon
an adverse decision on appeal. If the Company’s Vice President of Human
Resources needs more than 90 days to make a decision, he or she shall notify the
Participant in writing within the initial 90 days and explain why more time is
required, and how long is needed. If a Participant (or any individual authorized
by such Participant) submits a claim according to the procedures above and does
not hear from the Company’s Vice President of Human Resources within the
appropriate time, the Participant may consider the claim denied.
11.2    Appeals. The following appeal procedures give the rules for appealing a
denied claim. If a claim for benefits is denied, in whole or in part, or if the
Participant believes benefits under the Plan have not been properly provided,
the Participant (or any individual authorized by such Participant) may appeal
this denial in writing within 60 days after the denial is received by filing a
written request for review with the Administrator. The Administrator shall
conduct a review and make a final decision within 60 days after receiving the
Participant’s written request for review. If the Administrator needs more than
60 days to make a decision, it shall notify the Participant in writing within
the initial 60 days and explain why more time is required and the date by which
the Administrator expects to render its decision. The Administrator may then
take 60 more days to make a decision. If such appeal is denied in whole or in
part, the decision shall be in writing and shall include the following
information: (a) specific reasons for the denial; (b) specific reference to
pertinent Plan provisions on which the denial is based; (c) a statement of the
Participant’s right to access and receive copies, upon request and free of
charge, of all documents and other information relevant to such claim for
benefits; and (d) a statement of the Participant’s (or representative’s) right
to bring a civil action under Section 502(a) of ERISA. If the Administrator does
not respond within the applicable time frame, the Participant may consider the
appeal denied. If a Participant’s claim is denied, in whole or in part, the
Participant (or any individual authorized by such Participant) will be provided,
upon request and free of charge, reasonable access to, and copies of, all
documents, records and other information relevant (within the meaning of 29
C.F.R. § 2560.503-1(m)(8)) to his or her claim. Likewise, a Participant (or any
individual authorized by such Participant) who submits a written request to
appeal a denied claim shall have the right to submit any comments, documents,
records or other information relating to the claim that he or she wishes to
provide.
11.3    Limitations Period. A Participant must pursue the claim and appeal
rights described above within 365 days following the date of which the
Participant knew of should have known that the benefits in dispute would not be
paid under the Plan. The Participant must exhaust the claim and appeals rights
described above before seeking any other legal recourse regarding a claim for
benefits. The Participant may thereafter file an action in a court of competent
jurisdiction, but he or she must do so within 365 days after the date of the
notice of decision on appeal or such action will be forever barred. Any judicial
review of the Administrator’s decision on a claim will be limited to whether, in
the particular instance, the Administrator abused its discretion. In no event
will such judicial review be on a de novo basis, because the Administrator has
discretionary authority to determine eligibility for (and the amount of)
payments and benefits under the Plan and to construe and interpret the terms and
provisions of the Plan.
11.4    Legal Fees. The Company shall pay to the Participant all legal fees and
expenses incurred by the Participant in disputing in good faith any issue
hereunder relating to the termination of the Participant’s employment or in
seeking in good faith to obtain or enforce any benefit or right provided by this
Plan. Any such payments shall be made within five (5) business days after
delivery of the Participant’s written requests for payment accompanied with such
evidence of fees and expenses incurred as the Company reasonably may require.
The Participant must submit the written reimbursement request described above
within 180 days following the date upon which the applicable fee or expense is
incurred.

12.
Notices, Effect of Dispute and Assignment.

12.1    General. Notices and all other communications contemplated by the Plan
shall be in writing and shall be deemed to have been duly given when personally
delivered or when mailed by U.S. registered or certified mail, return receipt
requested and postage prepaid. In the case of the Participant, mailed notices
shall be addressed to him or her at the home address that he or she most
recently communicated to the Company in writing. In the case of the Company,
mailed notices shall be addressed to its corporate headquarters, and all notices
shall be directed to the attention of its Vice President of Human Resources.
12.2    Notice of Termination by the Company. Any termination of employment by
the Company in connection with a Change in Control pursuant to the terms herein
shall be communicated by a notice of termination of employment to the
Participant at least five days prior to the date of such termination (or at
least 30 days prior to the date of a termination by reason of the Participant’s
Disability). Such notice shall indicate the specific provision or provisions in
the Plan applicable to the termination of employment (if any), shall set forth
in reasonable detail the facts and circumstances claimed to provide a basis for
termination under the provision or provisions so indicated, provide any
necessary cure period that may apply, and shall specify the termination date. If
a dispute arises regarding a purported Cause termination by the Company, then
the provisions of Section 12.4 shall apply.
12.3    Notice of Good Reason Termination by the Participant. For purposes of
the Plan, a Participant’s termination of employment shall be for Good Reason
only if (a) the Participant delivers written notice to the Company of the
existence of the condition which the Participant believes constitutes Good
Reason within 90 days of the initial existence of such condition (which notice
specifically identifies such condition), (b) the Company fails to remedy such
condition within 30 days after the date on which it receives such notice (the
“Good Reason Cure Period”), and (c) subject to the provisions of Section 12.4,
the Participant actually terminates employment with the Company within 90 days
after the expiration of the Good Reason Cure Period. If the Company fails to
remedy the condition constituting Good Reason during the Good Reason Cure Period
and the Participant decides to terminate his or her employment for Good Reason,
then the Participant shall provide the Company with written notice of such
intent to terminate employment. Subject to the first sentence of this Section
12.3, any such termination shall be effective on the date such notice of
termination is given to the Company, such later date specified therein, or, in
the event of a dispute, as set forth in Section 12.4. If a dispute arises
regarding whether a Good Reason condition has occurred and/or whether the
Company has remedied such condition, then the provisions of Section 12.4 shall
apply.
12.4    Dispute Concerning Termination. If, prior to the date of termination of
employment set forth in any notice of termination provided under Sections 12.2
or 12.3, either party provides the other with written notice of a dispute
concerning (a) the termination from employment, (b) the designation of the
termination as for Cause or not for Cause or for Good Reason or not for Good
Reason, as the case may be, or (c) other rights provided or available to
Participant under the Plan, the Participant’s date of termination shall be
deemed extended for purposes of the Plan to the maximum extent permitted under
Code Section 409A, and the Participant will continue to receive his or her full
compensation and benefits in effect when such notice was given, until the
earlier of (i) the date on which the Term of the Plan ends or (ii) the date on
which the dispute is finally resolved, whether by mutual written agreement of
the parties or by a final judgment, order or decree of the any court of
competent jurisdiction (which is not appealable or with respect to which the
time for appeal therefrom has expired and no appeal has been perfected);
provided, however, the date of termination shall be deemed extended by a notice
of dispute given by the Participant only if such notice is given in good faith
with a reasonable basis and the Participant pursues the resolution of such
dispute with reasonable diligence. If the date of termination is deemed extended
in accordance with this Section 12.4, the Company shall continue to pay the
Participant’s full compensation and benefits in effect when the notice giving
rise to the dispute was given, and such amounts shall be in addition to (and
without offset from) all other amounts due to Participant under this Plan.
12.5    Assignment by Company. The Company may assign its rights under the Plan
to an affiliate, and an affiliate may assign its rights under the Plan to
another affiliate of the Company or to the Company. In the case of any such
assignment, the term “Company” when used in the Plan shall mean the entity that
actually employs the Participant.
13.
Miscellaneous.

13.1    Governing Law, Jurisdiction and Venue. The Plan is intended to be, and
shall be interpreted as, an unfunded employee welfare benefit plan (within the
meaning of Section 3(1) of ERISA) for a select group of management or highly
compensated employees (within the meaning of 29 C.F.R. §2520.104-24) and it
shall be enforced in accordance with ERISA. Any Participant or other Person
filing an action related to the Plan shall be subject to the jurisdiction and
venue of the federal courts of the State of Delaware.
13.2    Employment Status. Except as may be provided under any other agreement
between a Participant and the Company, the employment of the Participant by the
Company is “at will” and may be terminated by either the Participant or the
Company at any time, subject to applicable law.
13.3    Indebtedness of Participant. If a Participant is indebted to the
Company, the Company reserves the right to offset any Severance Payments by the
amount of such indebtedness, to the full extent permitted by applicable law;
provided that such offset is structured in a manner intended to comply with Code
Section 409A.
13.4    Severability. In the event any provision of the Plan shall be held
illegal or invalid for any reason, the illegality or invalidity shall not affect
the remaining parts of the Plan, and the Plan shall be construed and enforced as
if the illegal or invalid provision had not been included. Further, the captions
of the Plan are not part of the provisions hereof and shall have no force and
effect.
13.5    Effect of Plan. The Plan, as amended, together with each Participant’s
applicable Notice of Participation shall completely replace and supersede any
prior version of the Plan and any other verbal or written promise, agreement,
document or communication concerning the payments or benefits under the Plan.
Without limiting the generality of the foregoing, effective immediately upon
delivery by the Participant of a signed Notice of Participation, except as
otherwise provided in Section 4.2(d), the Participant (a) thereby waives,
without need of any further agreement or action, any potential rights the
Participant may have to severance pay, equity acceleration or other benefits
specifically arising from or in respect of a Change in Control occurring during
the term of the Plan (including any such potential rights arising from any
verbal or written promise, offer letter, employment agreement, other agreement,
document, or communication between the Participant and the Company or
pre-existing practice of the Company with respect to such benefits, but
expressly excluding any rights to benefits arising from the Plan), and (b)
thereby agrees that, if the Participant has an existing agreement with the
Company relating to potential rights to severance pay, equity acceleration or
other benefits specifically arising from or in respect of a Change in Control,
those rights shall be deemed completely replaced and superseded by the
Participant’s rights under the Plan with respect to any Change in Control
occurring during the term of the Plan; provided that, except as specifically
modified (mutatis mutandis) by the foregoing subsection (b), such agreement
shall remain enforceable and in full force and effect. In addition, none of the
payments or benefits under the Plan shall be counted as “compensation” or any
equivalent term for purposes of determining benefits under other plans, programs
or practices owing to the Participant from the Company, except to the extent
expressly provided therein or required by applicable law. Except as otherwise
specifically provided for in the Plan, the Participant’s rights under all such
agreements, plans, provisions and practices continue to be subject to the
respective terms and conditions thereof.

shall have the same defined meanings in this Notice of Participation. As a
condition of receiving any payments or benefits under the Plan, you must sign
(and not revoke, if applicable) a Release, which Release must become effective

The cash Severance Payment which you are eligible to receive under Section 4.1.
of the Plan is as follows:

(A)
[two (2) times] [one (1) times] the sum of (A) your annual Base Salary, plus
(B) the amount of your annual bonus pursuant to the Company’s annual bonus plans
in which you participate during the fiscal year in which your Qualifying
Termination occurs, (the “Annual Bonus”) computed at the target amount of such
Annual Bonus, which calculation shall not, for the avoidance of doubt, take into
account any reductions that took effect on or after a Change in Control that
gave rise to a claim for resignation for Good Reason; plus

(B)
an amount equal to a prorated portion of your Annual Bonus calculated by
multiplying the greater of (A) (i) the target amount of such Annual Bonus or
(ii) if your Qualifying Termination occurs in the second half of the applicable
bonus period, the estimated actual amount of such Annual Bonus projected based
on the assumption of your continued employment through the applicable bonus
eligibility date and continued attainment of the applicable performance criteria
at the rate indicated by performance through your date of Qualifying Termination
by (B) a fraction, the numerator of which is the number of days in the
applicable fiscal year through the date of your Qualifying Termination and the
denominator of which is 365; plus

(C)
an amount equal to the Company’s estimate of the total cost of medical, dental
and vision continuation coverage under Company’s group health plan for you and
any of your participating dependents (based on your benefit elections as of the
date of Qualifying Termination) for a period of [24][12] months following your
date of Qualifying Termination, which shall be grossed up to offset the federal
and state taxes that will be applied to such payment.

If you agree to participate in the Plan on these terms and conditions, please
