1.
Employment Duties and Acceptance

 

(a) In accordance
with the terms of this Agreement, the Company hereby employs the Executive, for the Term (as hereinafter defined), to render full-time
services to the Company as President and Chief Executive Officer and to perform the customary duties and bear the customary responsibilities

therefor other than that specified in this Agreement, if elected to such position by the Board or the stockholders of the Company.
At all times during the Term, the Company shall include the Executive in the management slate for election as a director at every

(d) The principal
place of employment of the Executive hereunder shall at all times during the Term be in the Columbia, Maryland area or such other
location(s) as may be mutually acceptable to the Executive and the Board.

 

2. Term of Employment

 

The initial term
of the Executive’s employment under this Agreement (the “Term”) shall commence on the Effective Date and shall
end on the third anniversary of the Effective Date (the “Initial Term”), unless sooner terminated by the Company or
the Executive pursuant to Section 6, 7 or 8 of this Agreement, as the case may be, or voluntarily by the Executive. Notwithstanding
the foregoing, unless notice is given by the Executive or the Company to the other at least three (3) months prior to the expiration
of the Term of this Agreement (including at least three (3) months prior to the expiration of any extension hereof, as provided
below), the Term automatically shall be extended by one (1) year from the date it would otherwise end (whether upon expiration
of the initial Term or any extension(s) thereof), unless sooner terminated pursuant to Section 6, 7 or 8 hereof or voluntarily
by the Executive. In the event of such an automatic extension, the term “Term,” as used herein, shall include each
and any such extension.

 

3. Compensation and Benefits

 

(a) As compensation
for the services to be rendered pursuant to this Agreement, the Company agrees to pay the Executive, during the period from the
Effective Date through and including March 29, 2015, an annual base salary in the amount of two hundred fifty thousand dollars
($250,000.00) (the “Base Salary”). The Executive’s Base Salary hereunder shall be reviewed as of June 15th
2013 and at least annually thereafter during the Term of the Agreement for adjustment upward (but not downward) in the discretion
of the Board or the Compensation Committee of the Board (the “Compensation Committee”). The Executive’s Base
Salary, as so adjusted, shall be considered the new Base Salary for all purposes of this Agreement. The Base Salary shall be paid
in accordance with the Company’s standard payroll practices applicable to its senior executives.

 

(b) The Company agrees
that the Executive shall be eligible for a quarterly performance bonus of up to ten thousand dollars ($10,000.00) from the Company
with respect to each calendar year quarter of the Company that ends during the Term. The amount of any such performance bonus shall
be determined by the Board or the Compensation Committee of the Board in its sole and absolute discretion, consistent with the
Company’s performance, the Executive’s contribution to the Company’s performance and the provisions of any such
applicable incentive bonus program, policy or practice; provided, however, that on an annual basis the aggregate amount
of such quarterly performance bonuses shall not exceed twenty-five percent (25%) of the Base Salary for the fiscal year to which
the bonus applies except pursuant to a specific finding by the Board or the Compensation Committee of the Board that a higher percentage
is appropriate.

 

(c) The Company shall
grant the Executive incentive stock options (the “Inducement Options”) issued under section 422 of the Internal Revenue
Code of 1986 (the “Code”) to purchase four hundred fifty thousand (450,000) shares of the Company’s common stock,
par value $0.0001 per share (“Common Stock”) at one hundred ten percent (110%) of the fair market value per share of
common stock, as determined by the Board (the “Exercise Price”) on the date on which the Inducement Options are granted
(the “Grant Date”). The Inducement Options shall vest in three (3) equal installments of Inducement Options to purchase
150,000 shares on the first, second and third anniversaries of the Grant Date (each, an “Installment”); provided
that, if the Executive’s employment is terminated by the Company prior to the first anniversary of the Grant Date other than
pursuant to Section 6 of this Agreement, the first Installment of Inducement Options shall vest on the date of such termination
and the remainder of the Inducement Options shall not vest and shall be forfeited; further provided that, if the Executive
is not employed by the Company on the second, third or fourth anniversary of the Grant Date, the Installments vesting on and after
any such anniversary shall not vest and the Inducement Options included therein shall be forfeited. The Inducement Options shall
be exercisable, once vested, for a period ending on the fifth anniversary of the Grant Date at the Exercise Price. As soon as practicable
after the Grant Date, the Company shall prepare and file with the Securities and Exchange Commission a Registration Statement on
Form S-8 covering issuance of the shares underlying the Inducement Options. Such Inducement Options shall be issued under Parent’s
2012 Omnibus Stock Option Plan (the “Plan”) and shall be evidenced by a separate option agreement which shall be in
the standard form issued under the Plan, except as provided above.

(d) The Company agrees
to grant to the Executive, during the Term, at the time of its usual annual grant to employees for the applicable year, such options
to purchase shares of Common Stock as the Board or the Compensation Committee shall determine. In the event of a Change in Control
(as defined in Section 12), all stock options and stock awards (and similar equity rights) granted to the Executive prior to such
event, including, without limitation, the Inducement Options to be granted hereunder, shall immediately vest and become and remain
fully exercisable through their respective original terms and otherwise in accordance with their respective original terms.

 

(e) The Company shall
pay or reimburse the Executive for all reasonable expenses actually incurred or paid by the Executive during the Term in the performance
of services under this Agreement, upon presentation of expense statements or vouchers or such other supporting information as may
reasonably be required pursuant to the standard policies of the Company in effect from time to time.

 

(f) During the Term,
the Company shall, at its election, reimburse the Executive for term life insurance up to a maximum of one hundred fifty thousand
dollars ($150,000), or provide coverage for the Executive at such level.

 

(g) During the Term,
the Executive shall be eligible for paid vacation of 4 weeks per year after 10years of employment in accordance with the vacation
policy of the Company. In the event that Executive does not utilize all of his vacation in any calendar year, he may carry forward
up to two (2) weeks (10 days) for up to one (1) calendar year. Unused vacation days shall not otherwise accumulate.

 

4. Confidentiality

 

The Executive acknowledges
and agrees that the “Employee Proprietary Information and Ownership of Inventions Agreement” shall be deemed incorporated
in and made a part of this Employment Agreement. Notwithstanding any other provision of this Agreement, the Executive shall continue
to be bound by the terms of such Proprietary Information and Inventions Agreement for a period of five (5) years after the expiration
or termination of this Agreement for any reason. The Executive and the Company agree that following expiration or termination of
this Agreement for any reason the Proprietary Information and Inventions Agreement shall be applicable only to material, non-public,
proprietary information of the Company.

5. Non-Competition,
Non-Solicitation and Non-Disparagement

 

(a) During the Term,
the Executive shall not (1) provide any services, directly or indirectly, to any other business or commercial entity without the
consent of the Board or (2) participate in the formation of any business or commercial entity without the consent of the Board;
provided, however, that nothing contained in this Section 5(a) shall be deemed to prohibit the Executive from acquiring,
solely as an investment, shares of capital stock (or other interests) of any corporation (or other entity) not exceeding two percent
(2%) of such corporation’s (or other entity’s) then-outstanding shares of capital stock (or other interests).

 

(b) If this Agreement
is terminated by the Company for Cause (as defined in Section 6(c)) or if the Executive terminates this Agreement other than in
accordance with Section 7 or 8 hereof, or if the Executive is receiving Severance Payments in accordance with Section 9(c) or payments
under Section 9(d), then for a period of one (1) year following the date of termination the Executive shall not (1) provide any
services, directly or indirectly, to any other business or commercial entity in the Company’s Field of Interest (as defined
in Section 12), (2) solicit any customers or suppliers of the Company, (3) attempt to persuade or encourage customers or suppliers
of the Company not to do business with the Company and/or to do business with a competitor of the Company, (4) participate in the
formation of any business or commercial entity engaged primarily in the Company’s Field of Interest, or (5) directly or indirectly
employ, or seek to employ or secure the services in any capacity of, any person employed at that time by the Company or any of
its Affiliates, or otherwise encourage or entice any such person to leave such employment; provided, however, that nothing
contained in this Section 5(b) shall be deemed to prohibit the Executive from acquiring, solely as an investment, shares of capital
stock (or other interests) of any corporation (or other entity) in the Company’s Field of Interest not exceeding two percent
(2%) of such corporation’s (or other entity’s) then outstanding shares of capital stock (or other interests). This
Section 5(b) shall be subject to written waivers, which may be obtained by the Executive from the Company.

 

(c) At no time during
the Term of this Agreement or thereafter will the Executive knowingly make any written or oral untrue statement or any statement
that disparages the Company or its Affiliates or will the Company knowingly make any written or oral untrue statement or any statement
that disparages the Executive.

 

(d) If the Executive
commits a breach, or threatens to commit a breach, of any of the provisions of this Section 5, the Company shall have the right
and remedy to have the provisions of this Agreement, as the case may be, specifically enforced by any court having equity jurisdiction,
it being acknowledged and agreed that any such breach or threatened breach will cause irreparable injury to the Company and that
money damages will not provide an adequate remedy to the Company.

 

    	4

    	 

    

 

(e) If any of the
covenants contained in this Section 5 or any part hereof or thereof, is hereafter construed to be invalid, illegal or unenforceable
by a court or regulatory agency or tribunal of competent jurisdiction, such court, agency or tribunal shall have the power, and
hereby is directed, to substitute for or limit such provision(s) in order as closely as possible to effectuate the original intent
of the parties with respect to such invalid, illegal or unenforceable covenant(s) generally and so to enforce such substituted
covenant(s). Subject to the foregoing, the invalidity, illegality or unenforceability of any one or more of the covenants contained
in this Section 5 shall not affect the validity of any other provision hereof, which shall be given full effect without regard
to the invalid portions.

 

(f) If any of the
covenants contained in this Section 5, or any part hereof or thereof, is held to be unenforceable because of the duration of such
provision, the area covered thereby or the extent thereof, the parties agree that the tribunal making such determination shall
have the power, and hereby is directed, to reduce the duration, area and/or extent of such provision and, in its reduced form,
such provision shall then be enforceable.

 

(g) Anything else
contained in this Agreement to the contrary notwithstanding, the parties hereto intend to and hereby do confer jurisdiction to
enforce the covenants contained in this Section 5 A upon the courts of any state within the geographical scope of such covenants.
In the event that the courts of any one or more of such states shall hold any such covenant wholly unenforceable by reason of the
breadth of such scope or otherwise, it is the intention of the parties hereto that such determination not bar or in any way affect
the Company’s right to the relief provided above in the courts of any other state within the geographical scope of such other
covenants, as to breaches of such covenants in such other jurisdictions, the above covenants as they relate to each state being,
for this purpose, severable into diverse and independent covenants.

 

6. Termination
by the Company

 

During the Term of
this Agreement, the Company may terminate this Agreement, upon expiration of thirty (30) days’ prior written notice given
by the Company to the Executive (except in the case of the Executive’s death), if any one or more of the following shall
occur:

 

(a) The Executive
shall die during the Term; provided, however, that the Executive’s legal representatives shall be entitled to receive
(1) the Executive’s Base Salary through the date which is ninety (90) days after the Executive’s date of death and
(2) a pro rata annual performance bonus (prorated by multiplying the full year bonus that otherwise would be due by the percentage
derived from dividing the number of days in the then-current year prior to the death of the Executive by three hundred sixty-five
(365)) with respect to the fiscal year of the Company during which death occurs. Upon the Executive’s death, stock options
previously granted to the Executive that are vested and fully exercisable at the time of death shall remain fully exercisable,
by the Executive’s legal representatives, for a period of one hundred eighty (180) days from the date of death, at which
time they shall automatically be forfeited if not exercised. All stock options and stock awards (and similar equity rights) that
have not vested prior the date of death shall be forfeited.

 

    	5

    	 

    

 

(b) The Executive
shall become physically or mentally disabled so that the Executive is unable substantially to perform his services for (1) a period
of one hundred twenty (120) consecutive days or (2) shorter periods aggregating one hundred eighty (180) days during any twelve
(12) month period. Notwithstanding such disability the Company shall continue to pay the Executive his Base Salary through the
date of such termination. In addition, the Executive shall be entitled to a pro rata annual performance bonus (prorated by multiplying
the full year bonus that otherwise would be due by the percentage derived from dividing the number of days in the then-current
year prior to the termination on account of disability of the Executive by three hundred sixty-five (365)) with respect to the
fiscal year of the Company during which such termination occurs. Upon such a disability, stock options previously granted to the
Executive that are vested and fully exercisable at the time of disability shall remain fully exercisable, by the Executive or his
legal representatives, should he have such, for a period of one hundred eight (180) days from the date of disability, at which
time they shall automatically be forfeited if not exercised. All stock options and stock awards (and similar equity rights) that
have not vested prior to the date of disability shall be forfeited by the Executive.

 

(c) The Executive
acts, or fails to act, in a manner that provides Cause for termination. For purposes of this Agreement, the term “Cause”
means: (1) the Executive’s indictment for, or conviction of, any crime or serious offense involving money or other property
that constitutes a felony in the jurisdiction involved; (2) the Executive’s willful and ongoing neglect of, or failure to
discharge, duties (including fiduciary duties), responsibilities and obligations with respect to the Company hereunder; provided
such neglect or failure remains uncured for a period of thirty (30) days after written notice describing the same is given to the
Executive by the Company; (3) the Executive’s violation of any of the non-competition provisions of Section 5 hereof or the
Executive’s material breach of any provisions of Section 13 hereof hereto; or (4) any act of fraud or embezzlement by the
Executive involving the Company or any of its Affiliates.

 

7. Termination
by the Executive

 

The Executive may
terminate this Agreement on written notice to the Company in the event of a material breach of the terms of this Agreement by the
Company if such breach continues uncured for thirty (30) days after written notice describing the breach is first given to the
Company; provided, however, that the Executive may terminate this Agreement if such breach is for the payment of money and
continues uncured for ten (10) days after written notice describing such breach is first given. The Executive may also terminate
this Agreement upon written notice to the Company if any one or more of the following shall occur:

 

(a) loss of material
duties or authority of the Executive as President and/or Chief Executive Officer, and such loss continues for thirty (30) days
after written notice of such loss is given to the Company;

 

(b) a Prohibited
Event occurs; provided that the Executive gives written notice of termination within ninety (90) days after such occurrence
and such Prohibited Event is not remedied within thirty (30) days after such notice. For this purpose a “Prohibited Event”
exists if the Executive is not continuously at least one (1) of President or Chief Executive Officer of the Company during the
Term;

 

(c) the Company shall
make a general assignment for benefit of creditors, or any proceeding shall be instituted by the Company seeking to adjudicate
it as bankrupt or insolvent, or seeking liquidation, winding up, reorganization, arrangement, adjustment, protection, relief, or
composition of it or its debts under any law relating to bankruptcy, insolvency or reorganization or relief of debtors, or seeking
entry of an order for relief or the appointment of a receiver, trustee, or other similar official for it or for any substantial
part of its property, or the Company shall take any corporate action to authorize any of the actions set forth above in this Section
7(c);

 

    	6

    	 

    

 

(d) an involuntary
petition shall be filed or an action or proceeding otherwise commenced against the Company seeking reorganization, arrangement
or readjustment of the Company’s debts or for any other relief under the Federal Bankruptcy Code, as amended, or under any
other bankruptcy or insolvency act or law, state or federal, now or hereafter existing and shall remain undismissed or unstayed
for a period of thirty (30) days;

 

(e) a receiver, assignee,
liquidator, trustee or similar officer for the Company or for all or any part of its property shall be appointed involuntarily;
or

 

(f) a material breach
by the Company of any other material agreement with the Executive shall occur, if such breach continues uncured for thirty (30)
days after written notice describing such breach is first given to the Company; provided, however, that the Executive shall
be permitted to terminate this Agreement if such breach is for the payment of money and continues uncured for ten (10) days after
written notice describing such breach is first given.

 

8. Termination
Following a Change in Control 

 

(a) In addition to
the above, during the period commencing on the six (6) month anniversary of a Change in Control (as defined in Section 12) and
ending on the two (2) year anniversary of such Change in Control, the Executive may terminate this Agreement upon expiration of
ninety (90) days’ prior written notice if “Good Reason” exists for the Executive’s termination. For this
purpose, termination for “Good Reason” shall mean a termination by the Executive of his employment hereunder following
the occurrence, without his prior written consent, of any of the following events, unless the Company fully cures all grounds for
such termination within thirty (30) days after the Executive’s notice:

 

(i) any material
adverse change in the Executive’s authority, duties, titles or offices (including reporting responsibility), or any significant
increase in the Executive’s business travel obligations, from those existing immediately prior to the Change in Control;

 

(ii) any failure
by the Company to continue in effect any compensation plan in which the Executive participated immediately prior to such Change
in Control and which is material to the Executive’s total compensation, including, without limitation, to the Company’s
stock option, bonus and other plans or any substitute plans adopted prior to the Change in Control, unless an equitable arrangement
(embodied in an ongoing substitute or alternative plan) has been made with respect to such plan, or any failure by the Company
to continue the Executive’s participation therein (or in such substitute or alternative plan) on a basis no less favorable
to the Executive, both in terms of the amount of benefits provided and the level of the Executive’s participation relative
to other participants, as existed immediately prior to such Change in Control;

 

(iii) any failure
by the Company to continue to provide the Executive with benefits substantially similar to those enjoyed by the Executive under
any of the Company’s retirement, life insurance, medical, health and accident, or disability plans, programs or arrangements
in which the Executive was participating immediately prior to such Change in Control, the taking of any action by the Company that
would directly or indirectly materially reduce any of such benefits or deprive the Executive of any perquisite enjoyed by the Executive
at the time of such Change in Control, or the failure by the Company to maintain a vacation policy with respect to the Executive
that is at least as favorable as the vacation policy (whether formal or informal) in place with respect to the Executive immediately
prior to such Change in Control; or

    	7

    	 

    
 

 

(iv) the failure
of the Company to obtain the assumption in writing of its obligation to perform this Agreement by any successor to all or substantially
all of the assets of the Company upon a merger, consolidation, sale or similar transaction.

 

(b) In addition,
the Executive may elect to terminate his employment, at his own initiative, for any reason or for no reason, during the six (6)
month period commencing on the six (6) month anniversary of a Change in Control of the Company and ending on the one (1) year anniversary
of such Change in Control, in which case such termination of employment shall also be deemed to be for “Good Reason”.

 

9. Severance and
Benefit Continuation

 

(a) Termination
for Cause or Voluntary Termination by the Executive. If the Company terminates this Agreement for Cause pursuant to Section
6(c) hereof, or if the Executive voluntarily terminates this Agreement other than pursuant to Section 7 or 8 hereof (which termination
alone shall not constitute a breach of this Agreement), no severance or benefit continuation provisions shall apply; provided,
however, that the Executive shall have the same opportunity to continue group health benefits at the Executive’s expense
in accordance with the Consolidated Omnibus Budget Reconciliation Act of 1985 (“COBRA”) as is available generally to
other employees terminating employment with the Company. All stock options and stock awards (and similar equity rights) held by
the Executive that have vested prior to such termination of this Agreement may be exercised by the Executive for a period of ninety
(90) days after the date of termination, at which time they shall automatically be forfeited if not exercised. All stock options
and stock awards (and similar equity rights) that have not vested prior to such termination shall be forfeited by the Executive.
For purposes of this Agreement, an election by the Company not to renew this Agreement beyond the end of the then-current Term
shall be considered a termination of this Agreement.

 

(b) Termination
for Death or Disability. In the event of termination of this Agreement pursuant to Section 6(a) or 6(b) by reason of the death
or disability of the Executive, in addition to the Base Salary payments and pro rata annual performance bonus provided for in paragraph
(a) or (b) of Section 6, as applicable, the Company shall continue to provide all benefits subject to COBRA, at its sole cost and
expense, with respect to the Executive and his dependents for the maximum period provided by COBRA.

by the Company Without Cause or Termination by the Executive Based on a Material Breach by the Company. If (1) the Company
terminates this Agreement other than pursuant to Section 6 hereof or (2) the Executive terminates this Agreement pursuant to Section

Control of the Company, then:

(i) the Company
shall pay the Executive (x) in accordance with its normal payroll practice an amount equal to two (2) times the Executive’s
Base Salary at the time of his termination of employment for one (1) year from the date of termination (the “Severance Period”);
and (y) a pro rata annual performance bonus (prorated by multiplying the full year bonus that otherwise would be due by the percentage
derived from dividing the number of days in the then-current year prior to the termination of the Executive by three hundred sixty-five
(365)) with respect to the fiscal year of the Company during which such termination occurs;

 

(ii) all Company
employee benefit plans and programs, other than participation in any Company tax-qualified retirement plan, applicable to the Executive
shall be continued for the Severance Period (or, if such benefits are not available, or cannot be provided due to applicable law,
the Company shall pay the Executive a lump sum cash amount equal to the after-tax economic equivalent thereof; provided
that, with respect to any benefit to be provided on an insured basis, such lump sum cash value shall be the present value of the
premiums expected to be paid for such coverage, and with respect to other benefits, such value shall be the present value of the
expected cost to the Company of providing such benefits). In the case of all benefits subject to COBRA, the Company shall continue
to provide such benefits at its expense with respect to the Executive and his dependents for the maximum period provided by COBRA;
and

 

(iii) all stock
options and stock awards (and similar equity rights) that are vested at the time of termination shall remain fully exercisable
for a period of one hundred eight (180) days after the date of termination, at which time they shall automatically be forfeited
if not exercised. All stock options and stock awards (and similar equity rights) that have not vested prior to such termination
shall be forfeited by the Executive.

 

(d) Termination
by the Company Without Cause, Termination by the Executive for Good Reason, or Nonrenewal by the Company Upon a Change in Control.
If (1) the Company terminates this Agreement other than pursuant to Section 6 hereof or (2) the Executive terminates this Agreement
pursuant to Section 7 or 8, and in each case the termination of employment occurs within two (2) years of the consummation of a
Change in Control of the Company, then:

 

(i) the Company
shall pay the Executive (x) a cash lump immediately upon such termination of employment equal to two (2) times the Executive’s
Base Salary at the time of his termination of employment and (y) a pro rata annual performance bonus (prorated by multiplying the
full year bonus that otherwise would be due by the percentage derived from dividing the number of days in the then-current year
prior to the termination of the Executive by three hundred sixty-five (365)) with respect to the fiscal year of the Company during
which such termination occurs;

 

(ii) all Company
employee benefit plans and programs, other than participation in any Company tax-qualified retirement plan, applicable to the Executive
shall be continued for one (1) year from the date of such termination of employment (or, if such benefits are not available, or
cannot be provided due to applicable law, the Company shall pay the Executive a lump sum cash amount equal to the after-tax economic
equivalent thereof; provided that, with respect to any benefit to be provided on an insured basis, such lump sum
cash value shall be the present value of the premiums expected to be paid for such coverage, and with respect to other benefits,
such value shall be the present value of the expected cost to the Company of providing such benefits). In the case of all benefits
subject to COBRA, the Company shall continue to provide such benefits at its sole cost and expense with respect to the Executive
and his dependents for the maximum period provided by COBRA; and

 

    	9

    	 

    

 

(iii) all stock
options and awards of restricted stock (and similar equity rights), all of which shall have become fully vested pursuant to Section
3(d) hereof, shall remain fully exercisable through their respective original terms and otherwise in accordance with their respective
original terms as if no Change in Control had occurred.

 

(e) The payments
provided in Section 9(c) and 9(d) are intended as enhanced severance for a termination by the Company without Cause, or a termination
by the Executive in the circumstances provided. As a condition of receiving such payments, the Executive or his legal representatives,
should he have such, shall first execute and deliver a general release of all claims against the Company, its Affiliates, agents
and employees (other than any claims or rights pursuant to the Agreement or pursuant to equity or employee benefit plans), in a
form and substance satisfactory to the Company. In connection with such release by the Executive, the Company shall execute and
deliver a comparable release of claims against the Executive. Notwithstanding the foregoing, the Executive may elect to forego
the severance payments provided herein, in which event neither party shall be required to execute a release of the other. Notwithstanding
the foregoing provisions of this section 9(e), no release to be granted by the Executive shall be required to cause the Executive
to release the Company from, waive, or forego in any way any of the Executive’s rights to indemnification under the applicable
provisions of the Certificate of Incorporation or By-laws of the Company or any then-existing agreement between the Company and
the Executive with respect thereto.

 

10. Cooperation

 

Following the termination
of his employment, the Executive agrees to cooperate with, and assist, the Company to ensure a smooth transition in management
and, if requested by the Company, to make himself available to consult during regular business hours at mutually agreed upon times
for up to a three (3) month period thereafter. At any time following the termination of his employment, the Executive will provide
such information as the Company may request with respect to any Company- related transaction or other matter in which the Executive
was involved in any way while employed by the Company. The Executive further agrees, during the Term of this Agreement and thereafter,
to assist and cooperate with the Company in connection with the defense or prosecution of any claim that may be made against, or
by, the Company or its Affiliates, in connection with any dispute or claim of any kind involving the Company or its Affiliates,
including providing testimony in any proceeding before any arbitral, administrative, judicial, legislative or other body or agency.
The Executive shall be entitled to reimbursement for all properly documented expenses reasonably incurred in connection with rendering
transition services under this Section, including, without limitation, reimbursement for all reasonable travel, lodging, meal expenses
and legal fees.

 

11. No Mitigation

 

The Executive shall
not be required to mitigate the amount of any payment provided for hereunder by seeking other employment or otherwise, nor shall
the amount of any payment provided for hereunder be reduced by any compensation earned by the Executive as the result of employment
by another employer after the date of termination of employment by the Company.

    	15EMPLOYMENT AGREEMENT 

 

This EMPLOYMENT AGREEMENT
(the “Agreement”) is made and entered into effective as of the 30th day of March, 2012 (the “Effective Date”),
by and between Sand Hills, Inc., a Nevada corporation (the “Company”), and William J. Ochall, an individual (the “Executive”).

  

 

WITNESSETH 

 

WHEREAS, the
Company desires to retain the Executive to serve in the capacity of Chief Financial Officer of the Company on the terms and conditions
set forth in this Agreement; and

 

WHEREAS, the
Executive desires to accept employment in such capacity on such terms and conditions.

 

NOW, THEREFORE,
in consideration of the promises and the mutual covenants and agreements herein contained, and other good and valuable consideration,
the receipt and sufficiency of which are hereby acknowledged by the parties hereto, such parties, intending to be legally bound,
agree as follows:

 

1. Employment
Duties and Acceptance

 

(a) In accordance
with the terms of this Agreement, the Company hereby employs the Executive, for the Term (as hereinafter defined), to render full-time
services to the Company as Chief Financial Officer and to perform the customary duties and bear the customary responsibilities
of such position and such other duties and responsibilities, commensurate with such position, as the Executive shall be directed
from time to time by the Board of Directors of the Company (the “Board”) to perform or bear, which duties and responsibilities
shall be consistent with the provisions of the Bylaws of the Company in effect on the date hereof that relate to or bear upon the
duties of Chief Financial Officer all in accordance with the terms of this Agreement.

 

(b) The Executive
hereby accepts such employment and agrees to render the services described above, in accordance with the terms of this Agreement.

 

(c) The Executive
further agrees to accept election and to serve during all or any part of the Term as a director of the Company without any compensation
therefor other than that specified in this Agreement, if elected to such position by the Board or the stockholders of the Company.
At all times during the Term, the Company shall include the Executive in the management slate for election as a director at every
stockholders’ meeting at which his term as a director would otherwise expire. At the request of the Board, following termination
or expiration of this Agreement, the Executive promptly shall tender his resignation as a director of the Company. 

 

    	1

    	 

    
 

 

(d) The principal
place of employment of the Executive hereunder shall at all times during the Term be in the Columbia, Maryland area or such other
location(s) as may be mutually acceptable to the Executive and the Board.

 

2. Term of Employment

 

The initial term
of the Executive’s employment under this Agreement (the “Term”) shall commence on the Effective Date and shall
end on the third anniversary of the Effective Date (the “Initial Term”), unless sooner terminated by the Company or
the Executive pursuant to Section 6, 7 or 8 of this Agreement, as the case may be, or voluntarily by the Executive. Notwithstanding
the foregoing, unless notice is given by the Executive or the Company to the other at least three (3) months prior to the expiration
of the Term of this Agreement (including at least three (3) months prior to the expiration of any extension hereof, as provided
below), the Term automatically shall be extended by one (1) year from the date it would otherwise end (whether upon expiration
of the initial Term or any extension(s) thereof), unless sooner terminated pursuant to Section 6, 7 or 8 hereof or voluntarily
by the Executive. In the event of such an automatic extension, the term “Term,” as used herein, shall include each
and any such extension.

 

3. Compensation and Benefits

 

(a) As compensation
for the services to be rendered pursuant to this Agreement, the Company agrees to pay the Executive, during the period from the
Effective Date through and including March 29, 2015, an annual base salary in the amount of one hundred fifty thousand dollars
($150,000.00) (the “Base Salary”). The Executive’s Base Salary hereunder shall be reviewed as of June 15th
2013 and at least annually thereafter during the Term of the Agreement for adjustment upward (but not downward) in the discretion
of the Board or the Compensation Committee of the Board (the “Compensation Committee”). The Executive’s Base
Salary, as so adjusted, shall be considered the new Base Salary for all purposes of this Agreement. The Base Salary shall be paid
in accordance with the Company’s standard payroll practices applicable to its senior executives.

 

(b) The Company agrees
that the Executive shall be eligible for a quarterly performance bonus of up to five thousand dollars ($5,000.00) from the Company
with respect to each calendar year quarter of the Company that ends during the Term. The amount of any such performance bonus shall
be determined by the Board or the Compensation Committee of the Board in its sole and absolute discretion, consistent with the
Company’s performance, the Executive’s contribution to the Company’s performance and the provisions of any such
applicable incentive bonus program, policy or practice; provided, however, that on an annual basis the aggregate amount
of such quarterly performance bonuses shall not exceed twenty-five percent (25%) of the Base Salary for the fiscal year to which
the bonus applies except pursuant to a specific finding by the Board or the Compensation Committee of the Board that a higher percentage
is appropriate.

 

(c) The Company shall
grant the Executive incentive stock options (the “Inducement Options”) under section 422 of the Internal Revenue Code
(the “Code”) to purchase three hundred thousand (300,000) shares of the Company’s common stock, par value $0.0001
per share (“Common Stock”) at one hundred ten percent (110%) of the fair market value per share, as determined by the
Board (the “Exercise Price”) on the date on which the Inducement Options are granted (the “Grant Date”).
The Inducement Options shall vest in three (3) equal installments of Inducement Options to purchase 100,000 shares on the first,
second and third anniversaries of the Grant Date (each, an “Installment”); provided that, if the Executive’s
employment is terminated by the Company prior to the first anniversary of the Grant Date other than pursuant to Section 6 of this
Agreement, the first Installment of Inducement Options shall vest on the date of such termination and the remainder of the Inducement
Options shall not vest and shall be forfeited; further provided that, if the Executive is not employed by the Company on
the second or third anniversary of the Grant Date, the Installments vesting on and after any such anniversary shall not vest and
the Inducement Options included therein shall be forfeited. The Inducement Options shall be exercisable, once vested, for a period
ending on the fifth anniversary of the Grant Date at the Exercise Price. As soon as practicable after the Grant Date, the Company
shall prepare and file with the Securities and Exchange Commission a Registration Statement on Form S-8 covering issuance of the
shares underlying the Inducement Options. Such Inducement Options shall be issued under the Company’s 2012 Omnibus Stock
Option Plan (the “Plan”) and shall be evidenced by a separate option agreement which shall be in the standard form
issued under the Plan, except as provided above.

 

    	2

    	 

    
 

 

(d) The Company agrees
to grant to the Executive, during the Term, at the time of its usual annual grant to employees for the applicable year, such options
to purchase shares of Common Stock as the Board or the Compensation Committee shall determine. In the event of a Change in Control
(as defined in Section 12), all stock options and stock awards (and similar equity rights) granted to the Executive prior to such
event, including, without limitation, the Inducement Options to be granted hereunder, shall immediately vest and become and remain
fully exercisable through their respective original terms and otherwise in accordance with their respective original terms.

 

(e) The Company shall
pay or reimburse the Executive for all reasonable expenses actually incurred or paid by the Executive during the Term in the performance
of services under this Agreement, upon presentation of expense statements or vouchers or such other supporting information as may
reasonably be required pursuant to the standard policies of the Company in effect from time to time.

 

(f) During the Term,
the Company shall, at its election, reimburse the Executive for term life insurance up to one hundred fifty thousand dollars ($150,000),
or provide coverage for the Executive at such level.

 

(g) During the Term,
the Executive shall be eligible for paid vacation of 4 weeks per year after 10years of employment in accordance with the vacation
policy of the Company. In the event that Executive does not utilize all of his vacation in any calendar year, he may carry forward
up to two (2) weeks (10 days) for up to one (1) calendar year. Unused vacation days shall not otherwise accumulate.

 

4. Confidentiality

 

The Executive acknowledges
and agrees that the “Employee Proprietary Information and Ownership of Inventions Agreement” shall be deemed incorporated
in and made a part of this Employment Agreement. Notwithstanding any other provision of this Agreement, the Executive shall continue
to be bound by the terms of such Proprietary Information and Inventions Agreement for a period of five (5) years after the expiration
or termination of this Agreement for any reason. The Executive and the Company agree that following expiration or termination of
this Agreement for any reason the Proprietary Information and Inventions Agreement shall be applicable only to material, non-public,
proprietary information of the Company.

5. Non-Competition,
Non-Solicitation and Non-Disparagement

 

(a) During the Term,
the Executive shall not (1) provide any services, directly or indirectly, to any other business or commercial entity without the
consent of the Board or (2) participate in the formation of any business or commercial entity without the consent of the Board;
provided, however, that nothing contained in this Section 5(a) shall be deemed to prohibit the Executive from acquiring,
solely as an investment, shares of capital stock (or other interests) of any corporation (or other entity) not exceeding two percent
(2%) of such corporation’s (or other entity’s) then-outstanding shares of capital stock (or other interests).

 

(b) If this Agreement
is terminated by the Company for Cause (as defined in Section 6(c)) or if the Executive terminates this Agreement other than in
accordance with Section 7 or 8 hereof, or if the Executive is receiving Severance Payments in accordance with Section 9(c) or payments
under Section 9(d), then for a period of one (1) year following the date of termination the Executive shall not (1) provide any
services, directly or indirectly, to any other business or commercial entity in the Company’s Field of Interest (as defined
in Section 12), (2) solicit any customers or suppliers of the Company, (3) attempt to persuade or encourage customers or suppliers
of the Company not to do business with the Company and/or to do business with a competitor of the Company, (4) participate in the
formation of any business or commercial entity engaged primarily in the Company’s Field of Interest, or (5) directly or indirectly
employ, or seek to employ or secure the services in any capacity of, any person employed at that time by the Company or any of
its Affiliates, or otherwise encourage or entice any such person to leave such employment; provided, however, that nothing
contained in this Section 5(b) shall be deemed to prohibit the Executive from acquiring, solely as an investment, shares of capital
stock (or other interests) of any corporation (or other entity) in the Company’s Field of Interest not exceeding two percent
(2%) of such corporation’s (or other entity’s) then outstanding shares of capital stock (or other interests). This
Section 5(b) shall be subject to written waivers, which may be obtained by the Executive from the Company.

 

(c) At no time during
the Term of this Agreement or thereafter will the Executive knowingly make any written or oral untrue statement or any statement
that disparages the Company or its Affiliates or will the Company knowingly make any written or oral untrue statement or any statement
that disparages the Executive.

 

(d) If the Executive
commits a breach, or threatens to commit a breach, of any of the provisions of this Section 5, the Company shall have the right
and remedy to have the provisions of this Agreement, as the case may be, specifically enforced by any court having equity jurisdiction,
it being acknowledged and agreed that any such breach or threatened breach will cause irreparable injury to the Company and that
money damages will not provide an adequate remedy to the Company.

 

    	4

    	 

    

 

(e) If any of the
covenants contained in this Section 5 or any part hereof or thereof, is hereafter construed to be invalid, illegal or unenforceable
by a court or regulatory agency or tribunal of competent jurisdiction, such court, agency or tribunal shall have the power, and
hereby is directed, to substitute for or limit such provision(s) in order as closely as possible to effectuate the original intent
of the parties with respect to such invalid, illegal or unenforceable covenant(s) generally and so to enforce such substituted
covenant(s). Subject to the foregoing, the invalidity, illegality or unenforceability of any one or more of the covenants contained
in this Section 5 shall not affect the validity of any other provision hereof, which shall be given full effect without regard
to the invalid portions.

 

(f) If any of the
covenants contained in this Section 5, or any part hereof or thereof, is held to be unenforceable because of the duration of such
provision, the area covered thereby or the extent thereof, the parties agree that the tribunal making such determination shall
have the power, and hereby is directed, to reduce the duration, area and/or extent of such provision and, in its reduced form,
such provision shall then be enforceable.

 

(g) Anything else
contained in this Agreement to the contrary notwithstanding, the parties hereto intend to and hereby do confer jurisdiction to
enforce the covenants contained in this Section 5 A upon the courts of any state within the geographical scope of such covenants.
In the event that the courts of any one or more of such states shall hold any such covenant wholly unenforceable by reason of the
breadth of such scope or otherwise, it is the intention of the parties hereto that such determination not bar or in any way affect
the Company’s right to the relief provided above in the courts of any other state within the geographical scope of such other
covenants, as to breaches of such covenants in such other jurisdictions, the above covenants as they relate to each state being,
for this purpose, severable into diverse and independent covenants.

 

6. Termination
by the Company

 

During the Term of
this Agreement, the Company may terminate this Agreement, upon expiration of thirty (30) days’ prior written notice given

(a) The Executive
shall die during the Term; provided, however, that the Executive’s legal representatives shall be entitled to receive
(1) the Executive’s Base Salary through the date which is ninety (90) days after the Executive’s date of death and
(2) a pro rata annual performance bonus (prorated by multiplying the full year bonus that otherwise would be due by the percentage
derived from dividing the number of days in the then-current year prior to the death of the Executive by three hundred sixty-five
(365)) with respect to the fiscal year of the Company during which death occurs. Upon the Executive’s death, stock options
previously granted to the Executive that are vested and fully exercisable at the time of death shall remain fully exercisable,
by the Executive’s legal representatives, for a period of one hundred eighty (180) days from the date of death, at which
time they shall automatically be forfeited if not exercised. All stock options and stock awards (and similar equity rights) that
have not vested prior the date of death shall be forfeited.

 

(b) The Executive
shall become physically or mentally disabled so that the Executive is unable substantially to perform his services for (1) a period
of one hundred twenty (120) consecutive days or (2) shorter periods aggregating one hundred eighty (180) days during any twelve
(12) month period. Notwithstanding such disability the Company shall continue to pay the Executive his Base Salary through the
date of such termination. In addition, the Executive shall be entitled to a pro rata annual performance bonus (prorated by multiplying
the full year bonus that otherwise would be due by the percentage derived from dividing the number of days in the then-current
year prior to the termination on account of disability of the Executive by three hundred sixty-five (365)) with respect to the
fiscal year of the Company during which such termination occurs. Upon such a disability, stock options previously granted to the
Executive that are vested and fully exercisable at the time of disability shall remain fully exercisable, by the Executive or his
legal representatives, should he have such, for a period of one hundred eight (180) days from the date of disability, at which
time they shall automatically be forfeited if not exercised. All stock options and stock awards (and similar equity rights) that
have not vested prior to the date of disability shall be forfeited by the Executive.

that constitutes a felony in the jurisdiction involved; (2) the Executive’s willful and ongoing neglect of, or failure to
discharge, duties (including fiduciary duties), responsibilities and obligations with respect to the Company hereunder; provided
such neglect or failure remains uncured for a period of thirty (30) days after written notice describing the same is given to the
Executive by the Company; (3) the Executive’s violation of any of the non-competition provisions of Section 5 hereof or the
Executive’s material breach of any provisions of Section 13 hereof hereto; or (4) any act of fraud or embezzlement by the
Executive involving the Company or any of its Affiliates.

Company if such breach continues uncured for thirty (30) days after written notice describing the breach is first given to the
Company; provided, however, that the Executive may terminate this Agreement if such breach is for the payment of money and
continues uncured for ten (10) days after written notice describing such breach is first given. The Executive may also terminate
this Agreement upon written notice to the Company if any one or more of the following shall occur:

 

(a) loss of material
duties or authority of the Chief Financial Officer and such loss continues for thirty (30) days after written notice of such loss
is given to the Company;

 

(b) a Prohibited
Event occurs; provided that the Executive gives written notice of termination within ninety (90) days after such occurrence
and such Prohibited Event is not remedied within thirty (30) days after such notice. For this purpose a “Prohibited Event”
exists if the Executive is not continuously Chief Financial Officer of the Company during the Term;

 

(c) the Company shall
make a general assignment for benefit of creditors, or any proceeding shall be instituted by the Company seeking to adjudicate
it as bankrupt or insolvent, or seeking liquidation, winding up, reorganization, arrangement, adjustment, protection, relief, or
composition of it or its debts under any law relating to bankruptcy, insolvency or reorganization or relief of debtors, or seeking

other bankruptcy or insolvency act or law, state or federal, now or hereafter existing and shall remain undismissed or unstayed
for a period of thirty (30) days;

 

(e) a receiver, assignee,
liquidator, trustee or similar officer for the Company or for all or any part of its property shall be appointed involuntarily;

written notice describing such breach is first given.

 

8. Termination
Following a Change in Control 

 

(a) In addition to
the above, during the period commencing on the six (6) month anniversary of a Change in Control (as defined in Section 12) and
ending on the two (2) year anniversary of such Change in Control, the Executive may terminate this Agreement upon expiration of
ninety (90) days’ prior written notice if “Good Reason” exists for the Executive’s termination. For this
purpose, termination for “Good Reason” shall mean a termination by the Executive of his employment hereunder following
the occurrence, without his prior written consent, of any of the following events, unless the Company fully cures all grounds for
such termination within thirty (30) days after the Executive’s notice:

adverse change in the Executive’s authority, duties, titles or offices (including reporting responsibility), or any significant
increase in the Executive’s business travel obligations, from those existing immediately prior to the Change in Control;

 

(ii) any failure
by the Company to continue in effect any compensation plan in which the Executive participated immediately prior to such Change
in Control and which is material to the Executive’s total compensation, including, without limitation, to the Company’s
stock option, bonus and other plans or any substitute plans adopted prior to the Change in Control, unless an equitable arrangement
(embodied in an ongoing substitute or alternative plan) has been made with respect to such plan, or any failure by the Company
to continue the Executive’s participation therein (or in such substitute or alternative plan) on a basis no less favorable
to the Executive, both in terms of the amount of benefits provided and the level of the Executive’s participation relative
to other participants, as existed immediately prior to such Change in Control;

 

(iii) any failure
by the Company to continue to provide the Executive with benefits substantially similar to those enjoyed by the Executive under
any of the Company’s retirement, life insurance, medical, health and accident, or disability plans, programs or arrangements
in which the Executive was participating immediately prior to such Change in Control, the taking of any action by the Company that
would directly or indirectly materially reduce any of such benefits or deprive the Executive of any perquisite enjoyed by the Executive

9. Severance and
Benefit Continuation

 

(a) Termination
for Cause or Voluntary Termination by the Executive. If the Company terminates this Agreement for Cause pursuant to Section
6(c) hereof, or if the Executive voluntarily terminates this Agreement other than pursuant to Section 7 or 8 hereof (which termination
alone shall not constitute a breach of this Agreement), no severance or benefit continuation provisions shall apply; provided,
however, that the Executive shall have the same opportunity to continue group health benefits at the Executive’s expense
in accordance with the Consolidated Omnibus Budget Reconciliation Act of 1985 (“COBRA”) as is available generally to
other employees terminating employment with the Company. All stock options and stock awards (and similar equity rights) held by
the Executive that have vested prior to such termination of this Agreement may be exercised by the Executive for a period of ninety
(90) days after the date of termination, at which time they shall automatically be forfeited if not exercised. All stock options
and stock awards (and similar equity rights) that have not vested prior to such termination shall be forfeited by the Executive.
For purposes of this Agreement, an election by the Company not to renew this Agreement beyond the end of the then-current Term
shall be considered a termination of this Agreement.

 

(b) Termination
for Death or Disability. In the event of termination of this Agreement pursuant to Section 6(a) or 6(b) by reason of the death
or disability of the Executive, in addition to the Base Salary payments and pro rata annual performance bonus provided for in paragraph
(a) or (b) of Section 6, as applicable, the Company shall continue to provide all benefits subject to COBRA, at its sole cost and
expense, with respect to the Executive and his dependents for the maximum period provided by COBRA.

 

(c) Termination
by the Company Without Cause or Termination by the Executive Based on a Material Breach by the Company. If (1) the Company
terminates this Agreement other than pursuant to Section 6 hereof or (2) the Executive terminates this Agreement pursuant to Section
7, and in each case the termination of employment does not occur within two (2) years following the consummation of a Change in
Control of the Company, then:

 

(i) the Company
shall pay the Executive (x) in accordance with its normal payroll practice an amount equal to the Executive’s Base Salary
at the time of his termination of employment for one (1) year from the date of termination (the “Severance Period”);
and (y) a pro rata annual performance bonus (prorated by multiplying the full year bonus that otherwise would be due by the percentage
derived from dividing the number of days in the then-current year prior to the termination of the Executive by three hundred sixty-five
(365)) with respect to the fiscal year of the Company during which such termination occurs;

 

    	8

    	 

    

 

(ii) all Company
employee benefit plans and programs, other than participation in any Company tax-qualified retirement plan, applicable to the Executive
shall be continued for the Severance Period (or, if such benefits are not available, or cannot be provided due to applicable law,
the Company shall pay the Executive a lump sum cash amount equal to the after-tax economic equivalent thereof; provided
that, with respect to any benefit to be provided on an insured basis, such lump sum cash value shall be the present value of the
premiums expected to be paid for such coverage, and with respect to other benefits, such value shall be the present value of the
expected cost to the Company of providing such benefits). In the case of all benefits subject to COBRA, the Company shall continue
to provide such benefits at its expense with respect to the Executive and his dependents for the maximum period provided by COBRA;
and

 

(iii) all stock
options and stock awards (and similar equity rights) that are vested at the time of termination shall remain fully exercisable
for a period of one hundred eight (180) days after the date of termination, at which time they shall automatically be forfeited
if not exercised. All stock options and stock awards (and similar equity rights) that have not vested prior to such termination
shall be forfeited by the Executive.

 

(d) Termination
by the Company Without Cause, Termination by the Executive for Good Reason, or Nonrenewal by the Company Upon a Change in Control.
If (1) the Company terminates this Agreement other than pursuant to Section 6 hereof or (2) the Executive terminates this Agreement
pursuant to Section 7 or 8, and in each case the termination of employment occurs within two (2) years of the consummation of a
Change in Control of the Company, then:

 

(i) the Company
shall pay the Executive (x) a cash lump immediately upon such termination of employment equal to the Executive’s Base Salary
at the time of his termination of employment and (y) a pro rata annual performance bonus (prorated by multiplying the full year
bonus that otherwise would be due by the percentage derived from dividing the number of days in the then-current year prior to
the termination of the Executive by three hundred sixty-five (365)) with respect to the fiscal year of the Company during which
such termination occurs;

 

(ii) all Company
employee benefit plans and programs, other than participation in any Company tax-qualified retirement plan, applicable to the Executive
shall be continued for one (1) year from the date of such termination of employment (or, if such benefits are not available, or
cannot be provided due to applicable law, the Company shall pay the Executive a lump sum cash amount equal to the after-tax economic
equivalent thereof; provided that, with respect to any benefit to be provided on an insured basis, such lump sum
cash value shall be the present value of the premiums expected to be paid for such coverage, and with respect to other benefits,
such value shall be the present value of the expected cost to the Company of providing such benefits). In the case of all benefits
subject to COBRA, the Company shall continue to provide such benefits at its sole cost and expense with respect to the Executive
and his dependents for the maximum period provided by COBRA; and

 

    	9

    	 

    

 

(iii) all stock
options and awards of restricted stock (and similar equity rights), all of which shall have become fully vested pursuant to Section
3(d) hereof, shall remain fully exercisable through their respective original terms and otherwise in accordance with their respective
original terms as if no Change in Control had occurred.

 

(e) The payments
provided in Section 9(c) and 9(d) are intended as enhanced severance for a termination by the Company without Cause, or a termination
by the Executive in the circumstances provided. As a condition of receiving such payments, the Executive or his legal representatives,
should he have such, shall first execute and deliver a general release of all claims against the Company, its Affiliates, agents
and employees (other than any claims or rights pursuant to the Agreement or pursuant to equity or employee benefit plans), in a
form and substance satisfactory to the Company. In connection with such release by the Executive, the Company shall execute and
deliver a comparable release of claims against the Executive. Notwithstanding the foregoing, the Executive may elect to forego
the severance payments provided herein, in which event neither party shall be required to execute a release of the other. Notwithstanding
the foregoing provisions of this section 9(e), no release to be granted by the Executive shall be required to cause the Executive
to release the Company from, waive, or forego in any way any of the Executive’s rights to indemnification under the applicable
provisions of the Certificate of Incorporation or By-laws of the Company or any then-existing agreement between the Company and
the Executive with respect thereto.

 

10. Cooperation

 

Following the termination
of his employment, the Executive agrees to cooperate with, and assist, the Company to ensure a smooth transition in management
and, if requested by the Company, to make himself available to consult during regular business hours at mutually agreed upon times
for up to a three (3) month period thereafter. At any time following the termination of his employment, the Executive will provide
such information as the Company may request with respect to any Company- related transaction or other matter in which the Executive
was involved in any way while employed by the Company. The Executive further agrees, during the Term of this Agreement and thereafter,
to assist and cooperate with the Company in connection with the defense or prosecution of any claim that may be made against, or
by, the Company or its Affiliates, in connection with any dispute or claim of any kind involving the Company or its Affiliates,
including providing testimony in any proceeding before any arbitral, administrative, judicial, legislative or other body or agency.
The Executive shall be entitled to reimbursement for all properly documented expenses reasonably incurred in connection with rendering
transition services under this Section, including, without limitation, reimbursement for all reasonable travel, lodging, meal expenses
and legal fees.

 

11. No Mitigation

 

The Executive shall
not be required to mitigate the amount of any payment provided for hereunder by seeking other employment or otherwise, nor shall
the amount of any payment provided for hereunder be reduced by any compensation earned by the Executive as the result of employment
by another employer after the date of termination of employment by the Company.
