MANAGEMENT RETENTION AGREEMENT

This Management Retention Agreement (the “Agreement”) is made and entered into
by and between David Gosen (the “Executive”) and Rocket Fuel Inc. (the
“Company”), effective as of the Effective Date (defined below). The purpose of
this Agreement is to provide assurances of specified benefits to Executive whose
employment is subject to being involuntarily terminated under the circumstances
described in this Agreement.

1.Definitions. The following words and phrases, when the initial letter of the
term is capitalized, will have the meanings set forth in this Section 1, unless
a different meaning is plainly required by the context:

1.1.    “Board” means the Board of Directors of the Company.

1.2.    “Cause” means, with respect to Executive, (i) an unauthorized use or
disclosure of the Company’s (or any subsidiary’s or parent’s of the Company)

material harm to the Company; (ii) a deliberate, material failure to comply with
any of the written policies or rules of the Company (or any employing subsidiary
or parent of the Company); (iii) conviction of, or plea of “guilty” or “no
contest” to, a felony under the laws of the United States or a criminal offence
under the laws of the United Kingdom (other than an offence under the road
traffic legislation in the United Kingdom for which the Executive is not
sentenced to any term of imprisonment, whether immediate or suspended); (iv)
gross misconduct; (v) a continued failure to perform assigned duties after
receiving written notification of such failure from the Board of Directors,
provided that such duties are those customarily performed by a person holding
the position that Executive holds immediately prior to the Change in Control
Period (defined below); or (vi) failure to cooperate in good faith with a
governmental or internal investigation of the Company (or any subsidiary or
parent of the Company) or its directors, officers or employees, if the Company
(or any subsidiary or parent of the Company) has requested the Executive’s
cooperation.

1.3.    “Change in Control” means the occurrence of any of the following on or
after the Effective Date of this Agreement:

(a)    A change in the ownership of the Company which occurs on the date that
any one person, or more than one person acting as a group (“Person”), acquires
ownership of the stock of the Company that, together with the stock held by such
Person, constitutes more than fifty percent (50%) of the total voting power of
the stock of the Company; provided, however, that for purposes of this
subsection, the acquisition of additional stock by any one Person, who is
considered to own more than fifty percent (50%) of the total voting power of the
stock of the Company will not be considered a Change in Control; or

(b)    A change in the effective control of the Company which occurs on the date
that a majority of members of the Board is replaced during any twelve (12) month
period by Directors whose appointment or election is not endorsed by a majority
of the members of the Board prior to the date of the appointment or election.
For purposes of this subsection (b), if any

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

Person is considered to be in effective control of the Company, the acquisition
of additional control of the Company by the same Person will not be considered a
Change in Control; or

(c)    a change in the ownership of a substantial portion of the Company’s
assets which occurs on the date that any Person acquires (or has acquired during
the twelve (12) month period ending on the date of the most recent acquisition
by such person or persons) assets from the Company that have a total gross fair
market value equal to or more than fifty percent (50%) of the total gross fair
market value of all of the assets of the Company immediately prior to such
acquisition or acquisitions; provided, however, that for purposes of this
subsection (c), the following will not constitute a change in the ownership of a
substantial portion of the Company’s assets: (A) a transfer to an entity that is
controlled by the Company’s stockholders immediately after the transfer, or (B)
a transfer of assets by the Company to: (1) a stockholder of the Company
(immediately before the asset transfer) in exchange for or with respect to the
Company’s stock, (2) an entity, fifty percent (50%) or more of the total value
or voting power of which is owned, directly or indirectly, by the Company, (3) a
Person, that owns, directly or indirectly, fifty percent (50%) or more of the
total value or voting power of all the outstanding stock of the Company, or (4)
an entity, at least fifty percent (50%) of the total value or voting power of
which is owned, directly or indirectly, by a Person described in this subsection
(c)(B)(3). For purposes of this subsection (c), gross fair market value means
the value of the assets of the Company, or the value of the assets being
disposed of, determined without regard to any liabilities associated with such
assets.

(d)    For purposes of this definition, persons will be considered to be acting
as a group if they are owners of a corporation or other entity that enters into
a merger, consolidation, purchase or acquisition of stock, or similar business
transaction with the Company.

(e)    Notwithstanding the foregoing, a transaction will not be deemed a Change
in Control unless the transaction qualifies as a change in control event within
the meaning of Code Section 409A, as it has been and may be amended from time to
time, and any proposed or final Treasury Regulations and Internal Revenue
Service guidance that has been promulgated or may be promulgated thereunder from
time to time.

(f)    Further and for the avoidance of doubt, a transaction will not constitute
a Change in Control if: (i) its sole purpose is to change the state of the
Company’s incorporation, or (ii) its sole purpose is to create a holding company
that will be owned in substantially the same proportions by the persons who held
the Company’s securities immediately before such transaction.

1.4.    “Change in Control Period” means the time period beginning on the date
that is three (3) months prior to the Change in Control and ending on the date
that is twelve (12) months following the Change in Control.

1.5.    “Code” means the United States Internal Revenue Code of 1986, as
amended.

2

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

1.6.
“Director” means a member of the Board.

1.7.    “Disability” means that the Executive has been unable to perform the
Executive’s duties as the result of the Executive’s incapacity due to physical
or mental illness, and such inability, at least twenty-six (26) weeks after its
commencement or 180 days in any consecutive twelve (12) month period, is
determined to be total and permanent by a physician selected by the Company or
its insurers and acceptable to the Executive or the Executive’s legal
representative (such agreement as to acceptability not to be unreasonably
withheld). During the term of this Agreement, termination of the Executive's
employment for Disability may only be effected by the Company (or any parent or
subsidiary of the Company employing the Executive) on giving at least thirty
(30) days’ written notice of termination to the Executive. In the event that the
Executive resumes the performance of substantially all of the Executive’s duties
hereunder before the termination of the Executive’s employment becomes
effective, the notice to terminate will automatically be deemed to have been
revoked.

1.8.    “Effective Date” means the later of the date upon which the Company’s
Board or a committee thereof approves the Company entering into this form of
Agreement or the date Executive's employment commences under the Services
Agreement.

1.9.    “Good Reason” means, the Executive’s resignation within thirty (30) days
following the end of the Cure Period (as defined below), following the
occurrence of one or more of the following without the Executive’s express
written consent: (a) a material reduction of Executive’s duties, position or
responsibilities, or the removal of Executive from such position and
responsibilities, either of which results in a material diminution of
Executive’s authority, duties or responsibilities, unless Executive is provided
with a comparable position (i.e., a position of equal or greater organizational
level, duties, authority, compensation and status); provided, however, that a
reduction in duties, position or responsibilities solely by virtue of the
Company being acquired and made part of a larger entity (as, for example, when
the Chief Executive Officer of the Company remains as such following a Change in
Control but is not made the Chief Executive Officer of the acquiring
corporation) will not constitute “Good Reason”; (b) a material reduction in
Executive’s base salary; or (c) a material relocation of the Executive’s
principal workplace, provided that a relocation of 35 miles or less, or a
relocation to the Executive’s home as his or her principal workplace, will not
be considered a material relocation. In addition, in order to qualify as Good
Reason, the Executive must not terminate employment with the Company without
first providing the Company with written notice of the acts or omissions
constituting the grounds for “Good Reason” within sixty (60) days of the initial
existence of the grounds for “Good Reason” and a reasonable cure period of
thirty (30) days following the date of written notice (the “Cure Period”), and
such grounds must not have been cured during such time.

1.10.    “Involuntary Termination” means a termination of employment of
Executive under the circumstances described in Section 2.

1.11.    “Pre-CIC Period” means the portion of the Change in Control Period that
occurs prior to the Change in Control.

3

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

1.12.    “Section 409A Limit” means two (2) times the lesser of: (i) Executive’s
annualized compensation based upon the annual rate of pay paid to Executive
during Executive’s taxable year preceding the Executive’s taxable year of the
Executive’s termination of employment as determined under, and with such
adjustments as are set forth in, United States Treasury Regulation
1.409A-1(b)(9)(iii)(A)(1) and any United States Internal Revenue Service
guidance issued with respect thereto; or (ii) the maximum amount that may be
taken into account under a qualified plan pursuant to Section 401(a)(17) of the
Code for the year in which Executive’s employment is terminated.

1.13.    "Service Agreement" means the Service Agreement entered into between
Executive and Rocket Fuel Limited, dated 10 May 2016.

1.14.    “Severance Benefits” means the compensation and other benefits that the
Executive will be provided in the circumstances described in Section 2.

1.15.
“Share” means a share of the Company’s common stock.

1.16.    “Target Bonus” means either (i) the Executive’s target bonus percentage
or target commission percentage multiplied by the Executive’s annual base
salary, or (ii) the target bonus amount or target commission amount (as
applicable), in each case, as in effect for the Company’s (or its successor’s)
fiscal year in which the Executive’s Involuntary Termination occurs.

2.
Involuntary Termination.

2.1.    Termination During the Change in Control Period. If, during the Change
in Control Period, (i) Executive terminates his or her employment with the
Company (or any parent or subsidiary of the Company) for Good Reason, or (ii)
the Company (or any parent or subsidiary of the Company) terminates the
Executive’s employment for a reason other than Cause and other than death or
Disability; or (iii) solely with respect to Equity Award Vesting Acceleration,
Executive’s employment is terminated due to death or Disability, then, subject
to the Executive’s compliance with Section 4, as applicable, the Company shall
cause Executive to receive the following Severance Benefits:

2.1.1.    Cash Severance Benefits. With respect to the circumstances described
in Section 2.1 (i) and (ii), a lump-sum payment of cash severance equal to the
sum of:
(a) twelve (12) months of the Executive’s annual base salary (as in effect
immediately prior to
(A) a Change in Control (if Executive’s employment terminates on or after the
Change in Control), or (B) the Executive’s termination, whichever is greater)
and (b) 100% of Executive’s Target Bonus for the Company fiscal year in which
the Executive’s employment terminated minus any bonus payments or commission
payments, as applicable actually paid to Executive prior to such termination for
such fiscal year’s performance. Subject to Section 5, such payment shall be made
on the Release Deadline Date (or, if Executive’s termination occurs during the
Pre-CIC Period, on the later of the Release Deadline Date or the date of the
Change in Control, subject to the provisions of Section 2.1.4);

4

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

2.1.2.    Continued Medical Benefits. With respect to the circumstances
described in Section 2.1 (i) and (ii), if the Executive has private medical
expenses insurance pursuant to paragraph 8 of the Services Agreement on the date
of the Executive’s Involuntary Termination, the Company shall cause Executive to
receive reimbursement of the agreed upon cost that is in effect immediately
prior to (A) a Change in Control (if Executive's employment terminates on or
after the Change in Control), or (B) the Executive's termination, whichever is
greater) for twelve (12) months following the Executive’s employment
termination. However, if the Company determines in its sole discretion that it
is overly burdensome or costly to provide the reimbursement benefits or to
provide such benefits without potentially violating applicable laws (including,
without limitation, Section 2716 of the United States Public Health Service Act
and the United States Employee Retirement Income Security Act of 1974, as
amended), the Company will in lieu thereof cause Executive to be provided a
taxable lump sum payment equal to the product of (1) the monthly cost provided
pursuant to paragraph 8.1(b)(i) of the Service Agreement in effect immediately
prior to (A) a Change in Control (if Executive's employment terminates on or
after the Change in Control), or (B) the Executive's termination, whichever is
greater, multiplied by 12 and (2) 1.5. Subject to Section 5, any payment
pursuant to the prior sentence shall be made on the Release Deadline Date (or,
if Executive’s termination occurs during the Pre CIC Period, on the later of the
Release Deadline Date or the date of the Change in Control, subject to the
provisions of Section 2.1.4); and

2.1.3.    Equity Award Vesting Acceleration. With respect to the circumstances
described in Section 2.1 (i) and (ii), or (iii), 100% of the Shares subject to
each of Executive’s then outstanding stock options, stock appreciation rights,
restricted stock units and other Company equity compensation awards, including
(subject to the provisions of this paragraph) performance-based vesting
full-value awards where the payout is either a fixed number of Shares or zero
Shares depending on whether the performance metric is obtained, shall
immediately accelerate vesting. With respect to performance-based vesting
full-value awards in which the performance period has not been completed prior
to the Executive’s termination date and where the number of Shares earned is
variable based upon the extent to which performance milestones are reached
(i.e., where the number of Shares earned based upon achieving performance
milestones can be more than one positive number), each such award shall
immediately accelerate vesting as described above as if one hundred percent of
the target performance levels had been achieved. With respect to
performance-based vesting full-value awards where the performance period has
been completed prior to the Executive’s termination date and that remain subject
to additional service-based vesting, such awards shall accelerate as described
above with respect only to the shares earned by virtue of attaining the
performance metrics during the performance period. Any Company stock options and
stock appreciation rights shall thereafter remain exercisable following the
Executive’s employment termination for the period prescribed in the respective
option and stock appreciation right agreements. Subject to Section 5, any
acceleration pursuant to this Section 2.1.3 shall occur upon (a) with respect to
any restricted stock, stock options and stock appreciation rights, the date the
Release becomes effective and irrevocable (or, if Executive’s termination occurs
during the Pre-CIC Period, on the later of the date the Release becomes
effective and irrevocable or the date of the Change in Control, subject to the
provisions of Section 2.1.4), and (b) with respect to any restricted stock
units, performance shares/units or similar equity awards, on the Release
Deadline Date (or, if Executive’s termination occurs during the Pre-CIC Period,
on the later of the

5

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

Release Deadline Date or the date of the Change in Control, subject to the
provisions of Section 2.1.4).

2.1.4.    Interaction with Section 2.2. For the avoidance of doubt, the payments
under this Section 2.1 are in place of and not in addition to, any payments to
which Executive may have become entitled under Section 2.2. To the extent
Executive began receiving payment under such Section 2.2, and, due to a Change
in Control, becomes eligible for payments under this Section 2.1, the payments
previously made under Section 2.2 shall be deemed to have been made under this
Section 2.1.

2.2.    Termination Other Than During the Change in Control Period. If (i)
Executive terminates his or her employment with the Company (or any parent or
subsidiary of the Company) for Good Reason, or (ii) the Company (or any parent
or subsidiary of the Company) terminates the Executive’s employment for a reason
other than Cause and other than the Executive’s death or Disability, and such
termination occurs other than during the Change in Control Period, then, subject
to the Executive’s compliance with Section 4, the Company shall cause Executive
to receive the following Severance Benefits:

2.2.1.    Cash Severance Benefits. A lump-sum payment of cash severance equal to
six (6) months of Executive’s annual base salary. Subject to Section 5, such
payment shall be made on the Release Deadline Date; and

2.2.2.    Continued Medical Benefits. If the Executive has private medical
expenses insurance pursuant to paragraph 8 of the Service Agreement on the date
of the Executive's termination of employment, the Company shall cause Executive
to receive reimbursement of the agreed upon cost that is in effect immediately
prior to the Executive's termination of employment for six (6) months following
the Executive’s employment termination. However, if the Company determines in
its sole discretion that it is overly burdensome or costly to provide the
reimbursement benefits or to provide such benefits without potentially violating
applicable laws (including, without limitation, Section 2716 of the United
States Public Health Service Act and the United States Employee Retirement
Income Security Act of 1974, as amended), the Company will, in lieu thereof,
cause Executive to be provided a taxable lump sum payment equal to the product
of (1) to the monthly cost provided pursuant to paragraph 8.1(b)(i) of the
Service Agreement in effect immediately prior to the Executive’s termination of
employment multiplied by and (2) 1.5. Subject to Section 5, any payment pursuant
to the prior sentence shall be made on the Release Deadline Date (or, if
Executive's termination occurs during the Pre-CIC Period, on the later of the
Release Deadline Date or the date of the Change in Control, subject to the
provisions of Section 2.1.4)

3.
Code Section 280G.

3.1.    Limitation on Payments. In the event that the payments and benefits
provided for in this Agreement or other payments and benefits payable or
provided to the Executive (i) constitute “parachute payments” within the meaning
of Section 280G of the Code and (ii) but for this Section 3, would be subject to
the excise tax imposed by Section 4999 of the Code (“Excise Tax”), then the
Executive’s payments and benefits under this Agreement or other payments or

6

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

benefits (the “Payment”) will be reduced to the Reduced Amount. The “Reduced
Amount” shall be either (x) the largest portion of the Payment that would result
in no portion of the Payment being subject to the Excise Tax or (y) the largest
portion, up to and including the total, of the Payment, whichever amount, after
taking into account all applicable federal, state and local employment taxes,
income taxes, and the Excise Tax (all computed at the highest applicable
marginal rate), results in Executive’s receipt, on an after-tax basis, of the
greater amount of the Payment notwithstanding that all or some portion of the
Payment may be subject to the Excise Tax. If a reduction in payments or benefits
constituting “parachute payments” is necessary so that the Payment equals the
Reduced Amount and no portion of such Payment will be subject to the excise tax
under Section 4999 of the Code, the reduction will occur in the following order:
(a) reduction of cash payments in reverse chronological order (that is, the cash
payment owed on the latest date following the occurrence of the event triggering
the excise tax will be the first cash payment to be reduced); (b) cancellation
of equity awards that were granted “contingent on a change in ownership or
control” within the meaning of Code Section 280G (if two or more equity awards
are granted on the same date, each award will be reduced on a pro- rata basis);
(c) reduction of the accelerated vesting of equity awards in the reverse order
of date of grant of the awards (i.e., the vesting of the most recently granted
equity awards will be cancelled first and if more than one equity award was made
to Executive on the same date of grant, all such awards shall have their
acceleration of vesting reduced pro rata); and (d) reduction of employee
benefits in reverse chronological order (i.e., the benefit owed on the latest
date following the occurrence of the event triggering the excise tax will be the
first benefit to be reduced). In no event will the Executive have any discretion
with respect to the ordering of payment reductions.

3.2.    Nationally Recognized Firm Requirement. Unless the Company and the
Executive otherwise agree in writing, any determination required under this
Section 3 will be made in writing by a nationally recognized accounting or
valuation firm (the “Firm”) selected by the Board or a committee of the Board,
whose determination will be conclusive and binding upon the Executive and the
Company for all purposes. For purposes of making the calculations required by
this Section 3, the Firm may make reasonable assumptions and approximations
concerning applicable taxes and may rely on reasonable, good faith
interpretations concerning the application of Sections 280G and 4999 of the
Code. The Company and the Executive will furnish to the Firm such information
and documents as the Firm may reasonably request in order to make a
determination under this Section 3. The Company will bear all costs for payment
of the Firm’s services in connection with any calculations contemplated by this
Section 3.

4.
Conditions to Receipt of Severance.

4.1.    Release Agreement. As a condition to receiving the Severance Benefits
under this Agreement, Executive will be required to sign and not revoke a
separation and release of claims agreement in a form reasonably satisfactory to
the Company (which may include an agreement not to disparage the Company, and
any parent or subsidiary of the Company, non-solicit provisions and other
standard terms and conditions) (the “Release”). In all cases, the Release must
become effective and irrevocable no later than the sixtieth (60th) day following
the date of the Executive’s Involuntary Termination (the “Release Deadline
Date”). If the Release does not become effective and irrevocable by the Release
Deadline Date, the Executive will forfeit any right to the Severance

7

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

Benefits. In no event will the Severance Benefits be paid or provided until the
Release becomes effective and irrevocable.

4.2.    Timing of Severance Benefits. Provided that the Release becomes
effective and irrevocable by the Release Deadline Date and subject to Section 5,
the severance payments and benefits under this Agreement will be paid, or in the
case of installments, will commence, on the Release Deadline Date (such payment
date, the “Severance Start Date”), and any severance payments or benefits
otherwise payable to the Executive during the period immediately following the
Executive’s termination of employment through the Severance Start Date will be
paid in a lump sum to the Executive on the Severance Start Date, with any
remaining payments to be made as provided in this Agreement.

4.3.    Exclusive Remedy; Non-Duplication of Benefits. The provisions of Section
2 are intended to be and are exclusive and in lieu of any other rights or
remedies to which Executive or the Company otherwise may be entitled, whether at
law, tort or contract, in equity, or under this Agreement (other than the
payment of accrued but unpaid salary, holiday entitlement, pension and other
paid employee benefits and reimbursable expenses due at termination or the
repayment of any salary received for holiday taken in excess of accrued
entitlement at the date of termination pursuant to the Service Agreement).
Termination of the Executive's employment shall be immediate under an
Involuntary Termination and Severance Benefits paid pursuant to Section 2 of
this Agreement shall be deemed inclusive of the payment in lieu of notice that
would otherwise be payable under clause 14 of the Service Agreement. Executive
hereby forfeits and waives any rights to any severance or change in control
benefits set forth in any employment agreement or offer letter, other than the
acceleration of vesting provisions in any of Executive’s written equity
compensation agreements, which remain in full force and effect, and as provided
by Section 14 below. For the avoidance of doubt, where the Executive's
employment is terminated during the term of this Agreement in circumstances that
do not constitute an Involuntary Termination, the notice requirements and
payment in lieu of notice provisions under clause 14of the Service Agreement
will apply. Notwithstanding any other provision in this Agreement to the
contrary, if, after the Effective Date, the Executive becomes entitled to any
severance, change in control or similar benefits outside of this Agreement by
operation of applicable law or under another policy, contract, or arrangement,
his or her benefits under this Agreement will be reduced by the value of the
severance, change in control, or similar benefits that the Executive receives by
operation of applicable law or under the policy, contract, or arrangement, all
as determined by the Board or a committee of the Board in its discretion. For
the avoidance of doubt, earned commissions and other wages due and payable upon
termination are not similar benefits.

4.4.    No Mitigation. The Executive shall not be required to mitigate the
amount of any severance payments or benefits provided for under this Agreement
by seeking other employment nor shall any amounts to be received by the
Executive under this Agreement be reduced by any other compensation earned.

5.Section 409A. This Section will apply if Executive is subject to United States
income taxes.

8

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

5.1.    Notwithstanding anything to the contrary in this Agreement, no severance
payments or benefits to be paid or provided to Executive, if any, under this
Agreement that, when considered together with any other severance payments or
separation benefits, are considered deferred compensation under Section 409A of
the Code, and the final regulations and any guidance promulgated thereunder
(“Section 409A”) (together, the “Deferred Payments”) will be paid or provided
until the Executive has a “separation from service” within the meaning of
Section 409A. Similarly, no severance payable to Executive, if any, under this
Agreement that otherwise would be exempt from Section 409A pursuant to United
States Treasury Regulation Section 1.409A-1(b)(9) will be payable until the
Executive has a “separation from service” within the meaning of Section 409A.

5.2.    It is intended that none of the severance payments or benefits under
this Agreement will constitute Deferred Payments but rather will be exempt from
Section 409A as a payment that would fall within the “short-term deferral
period” as described in Section 5.4 below or resulting from an involuntary
separation from service as described in Section 5.5 below. In no event will
Executive have discretion to determine the taxable year of payment of any
Deferred Payment.

5.3.    Notwithstanding anything to the contrary in this Agreement, if Executive
is a “specified employee” within the meaning of Section 409A at the time of the
Executive’s separation from service (other than due to death), then the Deferred
Payments, if any, that are payable within the first six (6) months following the
Executive’s separation from service, will become payable on the date six (6)
months and one (1) day following the date of the Executive’s separation from
service. All subsequent Deferred Payments, if any, will be payable in accordance
with the payment schedule applicable to each payment or benefit. Notwithstanding
anything herein to the contrary, in the event of the Executive’s death following
the Executive’s separation from service, but before the six (6) month
anniversary of the separation from service, then any payments delayed in
accordance with this paragraph will be payable in a lump sum as soon as
administratively practicable after the date of the Executive’s death and all
other Deferred Payments will be payable in accordance with the payment schedule
applicable to each payment or benefit. Each payment and benefit payable under
this Agreement is intended to constitute a separate payment under Section
1.409A-2(b)(2) of the Treasury Regulations.

5.4.    Any amount paid under this Agreement that satisfies the requirements of
the “short-term deferral” rule set forth in Section 1.409A-1(b)(4) of the
Treasury Regulations will not constitute Deferred Payments for purposes of
Section 5.1 above.

5.5.    Any amount paid under this Agreement that qualifies as a payment made as
a result of an involuntary separation from service pursuant to Section
1.409A-1(b)(9)(iii) of the Treasury Regulations that does not exceed the Section
409A Limit will not constitute Deferred Payments for purposes of Section 5.1
above.

5.6.    The foregoing provisions, and all payments and benefits provided under
this Agreement, are intended to comply with or be exempt from the requirements
of Section 409A so that none of the payments and benefits to be provided under
this Agreement will be subject to the

9

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

additional tax imposed under Section 409A, and any ambiguities or ambiguous
terms herein will be interpreted to so comply or be exempt. The Company and
Executive agree to consider in good faith amendments to this Agreement and to
take such reasonable actions which are necessary, appropriate or desirable to
avoid the imposition of any additional tax or income recognition under Section
409A prior to actual payments to Executive.

6.Withholdings. The Company will cause the withholding from any payments or
benefits under this Agreement all applicable U.S. federal, state, local and
non-U.S. taxes required to be withheld and any other required payroll
deductions.

7.Term. This Agreement will become effective upon the Effective Date and will
terminate automatically upon the completion of all payments (if any) under the
terms of this Agreement. However, in the event that a Change in Control has not
occurred by the date that is three (3) years following the Effective Date, this
Agreement will terminate automatically unless the term of this Agreement is
extended by the parties, provided, further, however, that if prior to the
expiration of the term of this Agreement, the Company enters into a definitive
agreement (a “Definitive Agreement”) with a third party (or third parties), the
consummation of which would result in a Change in Control (as defined in this
Agreement), then the term of this Agreement shall automatically be extended to
twenty-four months following the resulting Change in Control, unless the
Definitive Agreement terminates or is cancelled without resulting in a Change in
Control, in which case such extension shall not be effective. Moreover, this
Agreement shall survive the lapse of the term of this Agreement and shall be
binding on both parties with respect to any termination of Executive’s
employment that triggers Severance Benefits under Section 2 hereof that occurs
prior to the lapsing of the term of this Agreement.. Further, the decision by
either party not to extend the term of this Agreement will not by itself
constitute a termination of Executive’s employment by the Company other than for
Cause or grounds for Executive’s resignation for Good Reason, and unless
determined otherwise by Executive or the Company, after such non-renewal,
Executive’s employment will continue outside of this Agreement and pursuant to
the Service Agreement (or such employment agreement with the Company or a
subsidiary of the Company as then in effect) and Executive will not be eligible
for any severance payments or benefits under this Agreement.

8.No Enlargement of Employment Rights. Neither this Agreement, nor the making of
any benefit payment hereunder, will be construed to confer upon Executive any
right to continue to be an employee of the Company. The Company expressly
reserves the right to discharge any of its employees at any time, with or
without cause. However, as described in this Agreement, Executive may be
entitled to benefits pursuant to this Agreement depending upon the circumstances
of his or her termination of employment.

9.Successors. Any successor to the Company of all or substantially all of the
Company’s business and/or assets (whether direct or indirect and whether by
purchase, merger, consolidation, liquidation or other transaction) will assume
