SENIOR EXECUTIVE
RETENTION AGREEMENT (the “Agreement”), dated as of March 24, 2011 (the “Effective Date”)
by and between the SRA International, Inc., a Delaware corporation (the “Company”) and Tim Atkin
(the “Executive”).



The Board of Directors
of the Company (the “Board”) has determined that it is in the best interests of the Company and its shareholders
to assure that the Company and its affiliated companies will have the continued dedication of the Executive, notwithstanding the
possibility, threat or occurrence of a Potential Change in Control or a Change in Control of the Company. The Board believes that
it is imperative to diminish the inevitable distraction of the Executive by virtue of the personal uncertainties and risks created
by the circumstances surrounding a Potential Change in Control or a Change in Control and to encourage the Executive’s full
attention and dedication to the Company and its affiliated companies currently and in the event of any Potential Change in Control
or Change in Control (and, under certain circumstances, in the event of the termination or abandonment of a Change in Control transaction),
and to provide the Executive with compensation and benefits arrangements which ensure that the compensation and benefits expectations
of the Executive will be satisfied and which are competitive with those of other corporations. Therefore, in order to accomplish
these objectives, the Board has caused the Company to enter into this Agreement. Capitalized terms not otherwise defined in this
Agreement shall have the meaning set forth in Appendix A.



1. Term. The
“Term” of this Agreement is the period commencing on the Effective Date and ending on the second anniversary
thereof; provided, however, that commencing on the first anniversary of the Effective Date, and on each annual anniversary thereof
(such date and each annual anniversary thereof shall be hereinafter referred to as the “Renewal Date”), unless
previously terminated, the Term shall be automatically extended so as to terminate two years from such Renewal Date, unless at
least six months prior to the Renewal Date the Board shall give written notice to the Executive that the Term not be so extended.
Notwithstanding any notice to the Executive that the Term shall not be extended, the Term shall automatically be extended so as
to expire two years following the date of any Agreement Trigger. In the event a Change in Control occurs during the Term, the Term
shall be further extended until the end of the Employment Period or, if longer, until the Company has satisfied all of its obligations
hereunder.



2. Employment Period.
Subject to the terms and conditions of this Agreement, the Company hereby agrees to continue the Executive in the employ of the
Company or one of its affiliates for the period commencing on the first date on which a Change in Control occurs during the Term
and ending on the second anniversary of such date (the “Employment Period”).



3. Termination
of Employment.



(a) Termination.
The Executive’s employment during the Employment Period (i) shall automatically be terminated upon the Executive’s
death, (ii) may be terminated by the Company due to the Executive’s Disability, (iii) may be terminated by the
Company with or without Cause and (iv) may be terminated by the Executive with or without Good Reason.



(b) Qualifying Termination. Subject
to this Section 3(b), if, and only if, the Executive is terminated during the Employment Period (i) by the Company
for any reason other than (A) Cause or (B) due to the Executive’s Disability or death or (ii) by the Executive
for Good Reason (a “Qualifying Termination”), the Executive shall be entitled to the payments and benefits described
in Section 4.











(c) Disability.
The Company may terminate the Executive’s employment during the Employment Period due to the Executive’s Disability.
If the Company determines in good faith that the Disability of the Executive has occurred during the Employment Period, it may
give to the Executive written notice in accordance with Section 13(b) of its intention to terminate the Executive’s
employment. In such event, the Executive’s employment with the Company shall terminate effective on the 30th day after receipt
of such notice by the Executive (the “Disability Effective Date”).



(d) Notice of
Termination. Any termination of the Executive (other than due to the Executive’s death) during the Employment Period
by the Company or by the Executive shall be communicated by Notice of Termination to the other party hereto given in accordance
with Section 13(b).



4. Obligations
of the Company upon a Qualifying Termination: If the Executive’s employment with the Company and its affiliates is terminated
in a Qualifying Termination described in Section 3(b):



(a) The Company shall
pay or provide the Executive’s Accrued Obligations.



(b) Contingent upon
the Executive executing, delivering and not revoking, and the expiration of any applicable revocation period applicable to, a general
release in the form attached hereto as Exhibit A within 60 days of the Date of Termination, the Company shall pay or provide to
the Executive the following benefits or amounts:



i. A cash lump sum
in an amount equal to the sum of the Executive’s Base Salary and Target Bonus; provided, however, that such amount shall
be paid in lieu of, and the Executive hereby waives the right to receive, any other amount of severance relating to salary or bonus
continuation to be received by the Executive upon termination of employment of the Executive under any employment agreement or
severance plan, policy or arrangement of the Company.



ii. A cash lump sum in an amount equal
to a pro-rata portion of the Executive’s Target Bonus for the fiscal year in which the Executive’s termination occurs
(determined by multiplying the amount of the Target Bonus by a fraction, the numerator of which is the number of days during the
fiscal year of termination that the Executive is employed by the Company and the denominator of which is 365) (the “Pro
Rata Bonus”); provided that if such Qualifying Termination occurs before January 1, 2012, the Executive will receive
an amount equal to the greater of (i) the Executive’s Pro Rata Bonus or (ii) the amount by which the Executive’s
target bonus for the fiscal year ending June 30, 2011 exceeds the annual bonus actually paid to the Executive for the fiscal
year ending June 30, 2011. For the sake of clarity, if the Executive has not actually been paid an annual bonus for the fiscal
year ending June 30, 2011 at the time of the Qualifying Termination, the applicable amount paid to the Executive for the fiscal
year ending June 30, 2011 for purposes of calculating the amount under clause (ii) shall be $0, but the Executive shall
not be entitled to subsequently receive a bonus payment for the fiscal year ending June 30, 2011.



2







iii. The Company
shall provide the Executive with up to $25,000 annually of outplacement services during the two-year period following the Date
of Termination through and at the facilities of a reputable and experienced vendor selected by the Executive.



iv. If the Executive
validly elects COBRA continuation coverage, the Company shall pay the Executive up to twelve monthly payments in an amount sufficient,
on an after-tax basis, to pay the portion of the premium paid by the Company for medical coverage for its senior executives. The
Company may modify this clause (iv) to the minimum extent necessary to avoid any penalties imposed by law as a result of this
provision.



v. All outstanding
equity-based awards granted to the Executive shall be fully vested and earned, and any outstanding option, stock appreciation right,
and other outstanding award in the nature of a right that may be exercised that was granted to the Executive and that was not previously
exercisable and vested shall become fully exercisable and vested, and each such right (whether or not previously vested) held by
the Executive as of the Date of Termination shall remain exercisable in accordance with the applicable terms of such right, but
in any event until the earlier of the expiration of its original term and the six month anniversary of the Executive’s Date
of Termination. Payment in respect of the underlying awards hereof shall be made in the form of the equity security to which such
awards relate if such securities are then admitted for trading on a national securities exchange or are then admitted for quotation
on a national quotation system; provided that the Company may instead elect to settle such awards in cash. If such securities are
not so admitted, payment in respect of the underlying awards described in this subparagraph shall be made in cash based on the
fair market value of the securities (as determined by the board of directors of the issuer of such shares in good faith) to which
such awards relate.



(c) The Company shall
continue to pay the Executive’s Annual Base Salary during the pendency of a dispute over his termination. Amounts paid under
this Section 4(c) are in addition to all other amounts due under this Agreement and shall not be offset against or
reduce any other amounts due under this Agreement.



(d) In the event that that any payment
that is either received by the Executive or paid by the Company on the Executive’s behalf or any property, or any other benefit
provided to the Executive under this Agreement or under any other plan, arrangement or agreement with the Company or any other
person whose payments or benefits are treated as contingent on a change of ownership or control of the Company (or in the ownership
of a substantial portion of the assets of the Company) or any person affiliated with the Company or such person (but only if such
payment or other benefit is in connection with the Executive’s employment by the Company) (collectively the “Company
Payments”) would be subject to the tax imposed by Section 4999 of the Code (and any similar tax that may hereafter
be imposed by any taxing authority) (the “Excise Tax”), then the Executive will be entitled to receive either
(A) the full amount of the Company Payments, or (B) a portion of the Company Payments having a value equal to $1 less
than three (3) times the Executive’s “base amount” (as such term is defined in Section 280G(b)(3)(A)
of the Code) (the “Safe Harbor Amount”), whichever of clauses (A) and (B), after taking into account applicable
federal, state, and local income taxes and the Excise Tax, results in the receipt by the Executive on an after-tax basis, of the
greatest portion of the Company Payments. Any reduction of the Company Payments pursuant to the foregoing shall occur in the following
order: (A) any cash severance payable by reference to the Executive’s base salary or annual bonus; (B) any other
cash amount payable to the Executive; (C) any benefit valued as a “parachute payment;” and (D) acceleration
of vesting of any equity award. Any determination required under this Section 4(d)shall be made in writing by the
independent public accountants of the Company, whose determination shall be conclusive and binding for all purposes upon the Company
and the Executive. For purposes of making any calculation required by this Section 4(d), such accountants 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.



3







5. Other Terminations.
In the event the Executive’s employment is terminated during the Employment Period other than in a manner described in Section 3(b),
the Executive (or, as applicable, the Executive’s estate or designated beneficiaries) shall be entitled to receive the Accrued
Obligations.



6. Section 409A.
Notwithstanding the timing of the payments pursuant to Section 4, to the extent the Executive would otherwise be entitled
to a payment during the six months beginning on the Date of Termination that would be subject to the additional tax imposed under
Section 409A of the Code if it were made during such period pursuant to Section 409A(a)(2)(B), (i) the payment will
not be made to the Executive and instead will be made, at the election of the Company, either to a trust in compliance with Rev.
Proc. 92-64 or an escrow account established to fund such payments (provided that such funds shall be at all times subject to the
creditors of the Company and its affiliates) and (ii) the payment, together with interest thereon at the rate of “prime”
plus 1%, will be paid to the Executive on the earlier of the six-month anniversary of Date of Termination or the Executive’s
death or disability (within the meaning of Section 409A of the Code). Similarly, to the extent the Executive would otherwise
be entitled to any benefit (other than a cash payment) during the six months beginning on the Date of Termination that would be
subject to the additional tax under Section 409A of the Code, the benefit will be delayed and will begin being provided (together,
if applicable, with an adjustment to compensate the Executive for the delay, with such adjustment to be determined in the Company’s
reasonable good faith discretion) on the earlier of the six-month anniversary of the Date of Termination or the Executive’s
death or disability (within the meaning of Section 409A of the Code). The Company will establish the trust or escrow account,
as applicable, no later than ten days after the Executive’s Date of Termination. It is the intention of the parties that
the payments and benefits to which the Executive could become entitled in connection with termination of employment under this
Agreement comply with Section 409A of the Code. In the event that the parties determine that any such benefit or right does
not so comply, they will negotiate reasonably and in good faith to amend the terms of this Agreement such that it complies (in
a manner that attempts to minimize the economic impact of such amendment on the Executive and the Company and its affiliates).



4







For purposes of Section 409A of the
Code, the Executive’s right to receive any installment payments pursuant to this Agreement shall be treated as a right to
receive a series of separate and distinct payments. This Agreement is intended to comply with the requirements of Section 409A
of the Code, and specifically, with the separation pay exemption and short term deferral exemption of Section 409A, and shall,
in all respects be administered in accordance with Section 409A. Notwithstanding anything in the Agreement to the contrary,
distributions may only be made under the Agreement upon an event and in a manner permitted by section 409A of the Code or an applicable
exemption. All payments to be made upon a termination of employment under this Agreement may only be made upon a “separation
from service” under Section 409A. Any amounts payable solely on account of an involuntary separation from service of
Employee within the meaning of Section 409A (including separation from service for Good Reason) shall be excludible from the
requirements of Section 409A, either as involuntary separation pay or as short-term deferral amounts (e.g., amounts
payable under the schedule prior to March 15 of the calendar year following the calendar year of involuntary separation) to
the maximum possible extent. Any reimbursements or in-kind benefits provided under this Agreement shall be made or provided in
accordance with the requirements of Section 409A, including, where applicable, the requirement that (i) any reimbursement
is for expenses incurred during the period of time specified in this Agreement, (ii) the amount of expenses eligible for reimbursement,
or in kind benefits provided, during a calendar year may not affect the expenses eligible for reimbursement, or in kind benefits
to be provided, in any other calendar year, (iii) the reimbursement of an eligible expense will be made no later than the
last day of the calendar year following the year in which the expense is incurred, and (iv) the right to reimbursement or
in kind benefits is not subject to liquidation or exchange for another benefit.



Subject to this Section 6,
to the extent any payment pursuant to Section 4(b)(i), (ii), or (iv) is considered to be non-qualified
deferred compensation within the meaning of Section 409A of the Code, such payment shall be made on the 60th day following
the Date of Termination and shall include any payments that otherwise would have been made before such date.



7. Non-Exclusivity
of Rights. Except as otherwise expressly provided for in this Agreement, nothing in this Agreement shall prevent or limit the
Executive’s continuing or future participation in any plan, program, policy or practice provided by the Company or any of
its affiliated companies and for which the Executive may qualify, nor shall anything herein limit or otherwise affect such rights
as the Executive may have under any contract or agreement with the Company or any of its affiliated companies. Amounts which are
vested benefits or which the Executive is otherwise entitled to receive under any plan, policy, practice or program of or any contract
or agreement with the Company or any of its affiliated companies at or subsequent to the Date of Termination shall be payable in
accordance with such plan, policy, practice or program or contract or agreement except as explicitly modified by this Agreement.



8. No Offset.
The Company’s obligation to make the payments provided for in this Agreement and otherwise to perform its obligations hereunder
shall not be affected by any set-off, counterclaim, recoupment, defense or other claim, right or action which the Company may have
against the Executive or others. In no event shall the Executive be obligated to seek other employment or take any other action
by way of mitigation of the amounts payable to the Executive under any of the provisions of this Agreement and such amounts shall
not be reduced whether or not the Executive obtains other employment. The Company agrees to pay, to the fullest extent permitted
by law, all legal fees and expenses which the Executive may reasonably incur at all stages of proceedings, including, without limitation,
preparation and appellate review, as a result of any contest (regardless of whether formal legal proceedings are ever commenced
and regardless of the outcome thereof) by the Company, the Executive or others of the validity or enforceability of, or liability
under, any provision of this Agreement or any guarantee of performance thereof (including as a result of any contest by the Executive
about the amount of any payment pursuant to this Agreement), plus in each case interest on any delayed payment at the applicable
Federal rate provided for in Section 7872(f)(2)(A) of the Code.

available to the public other than as a result of a disclosure by the Executive in breach of this Agreement, (ii) was within
the Executive’s possession (as proven by the Executive) prior to its being furnished to him by or on behalf of the Company,
provided that the Executive believed in good faith that the source of such information was not bound by a confidentiality agreement
with, or other contractual, legal or fiduciary obligation of confidentiality to, the Company or any other party with respect to
such information, or (iii) becomes available to the Executive on a non-confidential basis from a source other than the Company
or any of its representatives, provided that the Executive believes in good faith that such source is not bound by a confidentiality
agreement with, or other contractual, legal or fiduciary obligation of confidentiality to, the Company or any other party with
respect to such information.

For the duration of and after the termination
of the Executive’s employment with the Company, the Executive agrees not to disclose, transfer, remove, copy or use, directly
or indirectly, any Proprietary Information for any purpose other than in the performance of his duties for the Company. The Executive
understands and agrees that disclosures authorized by the Company for the benefit of the Company must be made in accordance with
the Company policies and practices designed to maintain the confidentiality of Proprietary Information. Further, the Executive
agrees to use all reasonable measures to prevent the unauthorized use by others of Proprietary Information that the Executive has
in the Executive’s possession or control.



In the event the Executive receives a formal
demand pursuant to a subpoena or other validly issued administrative or judicial process or a governmental request (formal or informal)
for any Proprietary Information, the Executive shall promptly notify the Company and, in the case of a formal demand, tender to
it the defense thereof. Unless the formal demand shall have been timely limited, quashed, or extended or the governmental request
otherwise withdrawn, the Executive shall thereafter be entitled to comply with such demand or request to the extent permitted by
law. If requested by the Company, the Executive shall cooperate (at the expense of the Company) in the defense of a formal demand.



While the Executive is employed by the
Company, (i) the Executive agrees to not use or rely on the confidential or proprietary information or trade secrets of a
third party in the performance of his work for the Company except when obtained through lawful means such as contractual teaming
agreements, purchase of copyrights, or other written permission for use of such information, and (ii) except as otherwise
provided by Company policy, the Executive shall obtain prior written consent from an authorized officer of the Company for any

(a) solicit any employee of the Company or any of its subsidiaries or affiliates to discontinue that person’s employment
relationship with the Company or such entity, or (b) make any voluntary statements, written or oral, or cause or encourage
others to make any such statements that defame, disparage or in any way criticize the personal and/or business reputations, practices
or conduct of the Company, its subsidiaries or affiliates or any officer or director thereof, except that this provision shall
not be interpreted to prevent Executive from testifying in response to a subpoena. For a period of two (2) years after the
Date of Termination, the Company agrees that the officers and the Board members of the Company will not make any voluntary statements,
written or oral, or cause or encourage others to make any such statements that defame, disparage or in any way criticize the personal
and/or business reputations, practices or conduct of the Executive or otherwise disparage the Executive in any manner that is likely
to be harmful to the Executive’s business reputation, except that this provision shall not be interpreted to preventing any
such individuals from testifying in response to a subpoena.



7







11. Indemnification.
During the Employment Period and thereafter, the Company and its affiliates agrees to indemnify and hold the Executive and the
Executive’s heirs and representatives harmless, to the maximum extent permitted by law, against any and all damages, costs,
liabilities,losses and expenses (including reasonable attorneys’ fees) as a result of any claim or proceeding (whether civil,
criminal, administrative or investigative), or any threatened claim or proceeding (whether civil, criminal, administrative or
investigative), against the Executive that arises out of or relates to the Executive’s service as an officer, director or
employee, as the case may be, of the Company, or the Executive’s service in any such capacity or similar capacity with a
subsidiary or affiliate of the Company or other entity at the request of the Company, both prior to and after the Commencement
of the Term, and to promptly advance to the Executive or the Executive’s heirs or representatives such expenses upon written
request with appropriate documentation of such expense upon receipt of an undertaking by the Executive or on the Executive’s
behalf to repay such amount if it shall ultimately be determined that the Executive is not entitled to be indemnified by the Company.
During the Term and thereafter, the Company also shall provide the Executive with coverage under a current directors’ and
officers’ liability policy to the same extent that it or its affiliates provides such coverage to its other senior executives
of the Company. If the Company agrees in writing that it is responsible for the costs and resolution of such proceeding, the Company
shall be entitled to assume the defense of any such proceeding and the Executive will use reasonable efforts at the Company’s
expense to cooperate with such defense. To the extent that the Executive in good faith determines that there is an actual or potential
conflict of interest between the Company and the Executive in connection with the defense of a proceeding, the Executive shall
so notify the Company and shall be entitled to separate representation at the Company’s expense by counsel selected by the
Executive (provided that the Company may reasonably object to the selection of counsel within ten (10) business days after
notification thereof) which counsel shall cooperate, and coordinate the defense, with the Company’s counsel and minimize
the expense of such separate representation to the extent reasonably consistent with the Executive’s separate defense. The
Company shall not be liable for any settlement of any proceeding effected without its prior written consent, with such consent
not to be unreasonably withheld or delayed.



12. Successors.
This Agreement is personal to the Executive and without the prior written consent of the Company shall not be assignable by the
Executive otherwise than by will or the laws of descent and distribution. This Agreement shall inure to the benefit of and be enforceable
by the Executive’s legal representatives. This Agreement shall inure to the benefit of and be binding upon the Company and
its successors and assigns. The Company shall require any successor (whether direct or indirect, by purchase, merger, consolidation
or otherwise) to all or substantially all of the business and/or assets of the Company to assume expressly and agree to perform
this Agreement in the same manner and to the same extent that the Company would be required to perform it if no such succession
had taken place. As used in this Agreement, “Company” shall mean the Company as hereinbefore defined and any
successor to its business and/or assets as aforesaid which assumes and agrees to perform this Agreement by operation of law, or
otherwise.



13. Miscellaneous.

shall be governed by and construed in accordance with the laws of the Commonwealth of Virginia without reference to principles
of conflict of laws. The captions of this Agreement are not part of the provisions hereof and shall have no force or effect. This

extent not theretofore paid; (b) any accrued personal or banked leave, to the extent not theretofore paid; and (c) to
the extent not theretofore paid or provided, any other amounts or benefits required to be paid or provided or which the Executive

(including deferred compensation arrangements, but excluding severance or termination plans, policies and arrangements) in accordance
with its terms.



2. “Agreement
Trigger” means the earliest date on which any of the following events occurs (a) a Potential Change in Control occurs,
(b) the Board approves a plan of complete liquidation or dissolution of the Company, (c) a Change in Control occurs pursuant
to Section 5(a), (b) or (d) below or (d) a definitive agreement is signed by the Company which provides
for a transaction that, if approved by shareholders or consummated, as applicable, would result in a Change in Control pursuant
to Section 5(c) or (d)below.

4. “Cause”

(other than any such failure resulting from the Executive’s incapacity due to physical or mental illness) after a demand
for substantial performance is delivered to the Executive by the Board which specifically identifies the manner in which the Board
believes that the Executive has not substantially performed his duties, or (b) the willful engaging by the Executive in criminal
conduct that is materially and demonstrably injurious to the Company. No act or failure to act, on the Executive’s part shall
be considered “willful” unless done, or omitted to be done, by the Executive in bad faith and without reasonable belief
that the Executive’s action or omission was in, or not opposed to, the best interests of the Company. Any act, or failure

(b) of this paragraph and specifying the particulars thereof in detail.

voting power of then outstanding securities of the Company.

any person becoming a director subsequent to the date hereof whose election, or nomination for election by the Company shareholders,
was approved by a vote of at least a majority of the directors then comprising the Incumbent Board (other than an election or nomination
of an individual whose initial assumption of office is in connection with an actual or threatened election contest as such terms
are used in Rule 14a-11 of Regulation 14A promulgated under the Exchange Act relating to the election of the directors of the Company)
shall be, for purposes of this Agreement, considered as though such person were a member of the Incumbent Board; or



13







c. Merger or Asset
Sale and Material Change in Shareholders and Board: A merger, consolidation, reorganization or share exchange of the Company
(including a transaction involving a subsidiary of the Company that is intended to effect a change in control of the Company),

following such transaction, all of the following shall apply: (A) all or substantially all of the beneficial owners of the
Company immediately prior to such transaction will beneficially own in substantially the same proportions, directly or indirectly,
more than 50% of the combined voting power of the then outstanding voting securities of the corporation or other entity resulting
from such transaction (including, without limitation, a corporation or other entity which, as a result of such transaction, owns
the Company or all or substantially all of the Company assets, either directly or through one or more subsidiaries) (the “Successor
Entity”), (B) no Person (other than Ernst Volgenau, William Brehm or any Permitted Transferee of either Mr. Volgenau
or Mr. Brehm so long as such transferee continues to so qualify as a Permitted Transferee) will be the beneficial owner, directly
or indirectly, of 35% or more of the combined voting power of the then outstanding voting securities of the Successor Entity, and
(C) at least a majority of the members of the board of directors of the Successor Entity will be Incumbent Directors.



All terms used in
this definition shall be interpreted in a manner consistent with the Exchange Act.

the Executive for Good Reason, the date of receipt of the Notice of Termination or any later date specified therein, as the case
may be, (b) if the Executive’s employment is terminated by the Company other than for Cause or Disability, the Date
of Termination shall be the date on which the Company notifies the Executive of such termination, and (c) if the Executive’s
employment is terminated by reason of Disability, the Date of Termination shall be the Disability Effective Date.



7. “Disability”
shall mean the absence of the Executive from the Executive’s duties with the Company for 180 consecutive business days as
a result of incapacity due to mental or physical illness which 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 withheld unreasonably).



8. “Good
Reason” shall mean the Executive’s termination of employment if the Executive shall show that any of the following
has occurred: (i) a material adverse change in Executive’s title, duties, position, responsibilities or compensation;
(ii) the assignment of duties materially inconsistent with the Executive’s duties as of the Effective Date; (iii) a
material change in the Executive’s principal place of employment such that the Executive’s commuting distance as of
the date of the Effective Date increases by more than twenty-five (25) miles; (iv) a material breach of this Agreement
by the Company; or (v) failure by the Company to obtain written assumption of this Agreement by a purchaser or successor following
a Change in Control. Executive must give the Company written notice of any Good Reason termination of employment. Such notice must
be given within thirty (30) days following his knowledge of the first occurrence of a Good Reason circumstance set forth above.
Such notice must specify which of the circumstances set forth above the Executive is relying on and the particular action(s) or
inaction(s) giving rise to such circumstance. The Good Reason termination shall not be effective if, within ninety (90) days
of Company’s receipt of such notice, the Company remedies the circumstance(s) giving rise to the notice, or if the Executive’s
Date of Termination does not occur within thirty (30) days after the end of the ninety (90)-day period provided to the Company
to remedy the circumstances giving rise to the notice.

of Termination” shall mean a written notice which (a) indicates the specific termination provision in this Agreement
relied upon, (b) to the extent applicable, sets forth in reasonable detail the facts and circumstances claimed to provide
a basis for termination of the Executive’s employment under the provision so indicated, and (c) if the Date of Termination
is other than the date of receipt of such notice, specifies the Date of Termination (which, except in the case of a termination
due to a Disability, date shall be not more than fifteen days after the giving of such notice). The failure by the Executive or
the Company to set forth in the Notice of Termination any fact or circumstances which contributes to a showing of Good Reason or
Cause shall not waive any right of the Executive or the Company hereunder or preclude the Executive or the Company from asserting
such fact or circumstance in enforcing the Executive’s or the Company’s rights hereunder.



10. “Potential
Change in Control” means the occurrence of any of the following: (a) the Company or any individual, entity or group
(within the meaning of Section 13(d)(3) or 14(d)(2) of the Exchange Act) publicly announces or otherwise communicates to the
Board in writing an intention to take or to consider taking actions (i.e., a “bear hug” letter, an unsolicited
offer or the commencement of a proxy contest) which, if consummated or approved by shareholders, as applicable, would constitute
a Change in Control; or (b) any Person (other than an Excluded Person) directly or indirectly, acquires beneficial ownership
of 15% or more of the Outstanding Company Voting Securities.



11. “Target
Bonus” means the greater of the Executive’s target annual bonus in effect immediately prior to (a) the Change
in Control and (b) the Executive’s Date of Termination.
