Exhibit 10.1

EMPLOYMENT AGREEMENT

        THIS EMPLOYMENT AGREEMENT (this "Agreement") is made as of this 31st day
of December, 2007, by and between, Haverstick Consulting, Inc., an Indiana
corporation (the "Company"), and Howard W. Bates, an Indiana resident
("Executive").

        WHEREAS, the Company and Kratos Defense & Security Solutions, Inc., a
Delaware corporation ("Kratos"), and Kratos Government Solutions, Inc., a wholly
owned subsidiary of Kratos ("KGS"), have entered into a Merger Agreement dated
November 2, 2007 (the "Merger Agreement") whereby a wholly-owned newly-formed
merger subsidiary of KGS is being merged with and into the Company, with the
Company being the surviving corporation;

        WHEREAS, Executive has been a shareholder and key employee of the
Company for many years and is intimately familiar with the Company and its
business; and

        WHEREAS, the Company desires that Executive continue to provide services
for the benefit of the Company and Executive desires to accept such continued
employment with the Company; and

        WHEREAS, the execution and delivery of this Agreement is a condition
precedent to Kratos', KGS' and the Company's obligations under the Merger
Agreement; and

        WHEREAS, upon consummation of the transactions contemplated by the
Merger Agreement the Company will be a wholly-owned subsidiary of KGS.

        NOW, THEREFORE, in consideration of the recitals, the employment of
Executive by the Company, and the promises and covenants stated in this
Agreement, the parties agree as follows:

        1.     Employment.    The Company shall employ Executive as President of
the Company, such position being the president of a subsidiary of Kratos, and
Executive hereby accepts such employment by the Company subject to the terms and
conditions of this Agreement.

        2.     Duties.

        (a)   Executive shall report to, and shall have the powers, authority
and duties assigned by, the President and CEO of Kratos and CEO of the Company
(the "CEO"). It is understood by Executive and agreed by the Company, that such
powers, authority and duties of the Executive as President of the Company shall
always be consistent with those which are customary for, commensurate with, or
necessary to the position of President of a subsidiary of a public company, or
as that position is modified per Section 2(c) below. Throughout the Term (as
defined in Section 3), Executive shall: (i) devote the Executive's business
effort, time, energy and skill to the duties of Executive's employment
hereunder; (ii) faithfully, loyally, and industriously perform such duties; and
(iii) diligently follow and implement the lawful management policies and
decisions of the Board or the CEO that are communicated to Executive. During the
Term, Executive shall not be engaged during normal business hours in any other
business or professional activity, whether or not such activity is pursued for
gain, profit or other pecuniary advantage; provided, however, that Executive may
(i) serve on religious, industry, civic or charitable boards or committees,
(ii) deliver lectures, fulfill speaking engagements and teach at educational
institutions, (iii) devote time to his personal and family matters (including
without limitation his and their investments and business affairs), or
(iv) serve, with the approval of the CEO, which approval shall not be
unreasonably withheld, on the boards of directors of non-competitive businesses,
so long as such activities do not interfere with the performance of Executive's
responsibilities as an employee of the Company in accordance with this
Agreement.

        (b)   Executive shall maintain his office at the Company's corporate
offices located in Indianapolis, Indiana, from which his services to the Company
shall be rendered. Executive may be required to relocate from such office but
shall not be required to relocate to a site outside of the area represented by
Marion County, Indiana, and the counties contiguous to Marion County,

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

Indiana, without (i) the prior written consent of Executive and (ii) a
comprehensive relocation package. Notwithstanding the foregoing, Executive shall
be required to travel from time to time in accordance with the past practices of
Executive as shall be reasonably required for the fulfillment of his duties
hereunder.

        (c)   It is understood by Executive that it may be in the best interests
of Kratos to reorganize its various business units from time to time. Provided
that in any such reorganization the position of the Executive is maintained
reasonably equivalent to his position as a president of the Company as
subsidiary, there shall be no breach of this Section 2. For example, Kratos may
combine all business units into one corporate entity and dissolve the subsidiary
corporations, in which case the presidents of the subsidiaries will then be
named as presidents of divisions or sectors. The term "reasonably equivalent"
shall include the title, powers, authority, duties, responsibilities, bonus
potential, base salary, business unit size and other appropriate measures.

        3.     Term.    Subject to early termination pursuant to Section 5
hereof, the term of Executive's employment with the Company under this Agreement
shall commence as of the close of business on December 31, 2007 (the
"Commencement Date") and shall end on December 31, 2010 (the "Term"). The
Company and the Executive agree that they shall have the option to renew this
Agreement for subsequent terms. The CEO and Executive shall discuss the renewal
of this Agreement on or about January 15, 2010.

        4.     Compensation.    During the Term, Executive shall be entitled to
the compensation and benefits set forth in this Section. The payment of any
compensation hereunder shall be subject to applicable withholding and payroll
taxes, and such other deductions as may be required under the employee benefit
plans of the Company and/or its affiliates, and shall be paid in accordance with
the normal payroll and incentive administration practices of the Company and/or
its affiliates as they may exist from time to time, but not less frequently than
monthly.

        (a)   Salary.    The Company shall pay Executive an annual salary of not
less than $250,000 (the "Salary"). Commencing in the first quarter of fiscal
year 2009, Executive shall receive an annual performance and salary review, with
any corresponding increase in the Salary to be determined by the Compensation
Committee of the Board of Directors of Kratos, in its sole discretion.

        (b)   Annual Bonus.    For each of the three fiscal years of the Company
commencing January 1, 2008, January 1, 2009, January 1, 2010, respectively,
Executive shall be eligible to earn an annual bonus (the "Bonus") up to an
amount equal to the Salary. As a president of a subsidiary, he will be eligible
to earn up to fifty percent (50%) of his salary for making the revenue and
profit numbers in his annual operating plan ("AOP"). If the Company exceeds
revenue and profit numbers in the AOP by specific targets, Executive shall be
eligible to earn up to an aggregate amount equal to his Salary. At or about the
beginning of each fiscal year, the CEO shall present the Executive with his
bonus target criteria ("Bonus Letter"), which shall be tied to the Company's AOP
and other factors used by Kratos with all operating units. Except as otherwise
provided in Section 6(b), in the event that the Executive is employed by the
Company only a portion of a fiscal year, the Bonus shall be calculated to
reflect the portion of such fiscal year for which the Executive was employed by
the Company under this Agreement, and tied to the above described performance
criteria through the portion of the fiscal year completed. Within one hundred
twenty (120) days after the end of each fiscal year for which a Bonus may be
payable hereunder, the Company shall determine from its financial records and/or
financial statements whether or not a Bonus has been earned and the amount of
any Bonus payable. Any Bonus shall be paid to Executive at the same time as
bonuses are paid generally to other officers of Kratos.

        (c)   Expense Reimbursement.    Executive will be entitled to prompt
reimbursement for all necessary and reasonable business expenses incurred by
Executive in connection with the business of the Company, subject to Executive's
compliance with expense reimbursement policies

2

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

established by the Company and/or its affiliates from time to time and in
sufficient detail to comply with Internal Revenue Service regulations.

        (d)   Retirement Plans.    Executive shall be eligible to participate in
all present and future pension benefit and retirement plans, practices, policies
and programs established or maintained by the Company and/or its affiliates from
time to time to the extent applicable generally to executive officers of the
Company and/or its affiliates with the same years of service.

        (e)   Welfare Benefit Plans.    Executive and/or Executive's family, as
the case may be, shall be eligible to participate in any present and future
welfare, fringe, and other similar benefit plans, including, without limitation,
participation in any hospitalization, major medical, disability and group life
insurance plans, if any, practices, policies and programs established or
maintained by the Company and/or its affiliates from time to time to the extent
applicable generally to executive officers of the Company and/or its affiliates
with the same years of service. Notwithstanding, and in addition to, the
foregoing, the Executive shall be entitled to the following: (i) payment by the
Company of 100 percent of the premiums at Commencement Date for disability
insurance coverage not less than the coverage as of the Commencement Date,
(ii) payment by the Company of 100 percent of the premiums at Commencement Date
for family coverage for medical insurance, dental insurance and other ancillary
insurance and plan benefits with coverage not less than the coverage as of the
Commencement Date, and (iii) payment by the Company of all charges, costs,
expenses and premiums at Commencement Date related to Priority Access medical
service. Any premium increases in these above listed benefits from the premiums
paid at Commencement Date, shall be borne by Executive, unless approved by the
Compensation Committee of the Board of Directors of Kratos.

        (f)    Equity Plans.    Commencing with the fiscal year beginning
January 1, 2008, Executive shall be eligible to participate in all present and
future equity incentive plans established by the Kratos to the same extent
applicable generally to executive officers of the Kratos with the same years of
service.

        (g)   Paid Time Off.    Executive shall be eligible for no less than
that amount of paid time off during the Term established by the Company and/or
its affiliates from time to time as is provided to employees who are executive
officers of the Company and/or its affiliates with the same years of service;
provided, however, that Executive shall be entitled to at least six weeks of
paid time off with pay each year and Executive shall be entitled to carry over
such unused paid time off as is consistent with the policies of Kratos. Upon
expiration of the Term or earlier termination of the Executive's employment with
the Company, the Executive shall be paid for all unused paid time off.

        (h)   Restricted Stock.    Effective on December 28, 2007, Executive
shall be awarded 75,000 Restricted Stock Units ("RSUs) related to Common Stock
of Kratos pursuant to the terms of the Restricted Stock Unit Agreement attached
hereto as Exhibit A (the "Restricted Stock Unit Agreement"). The restrictions on
such RSUs shall lapse at the rate of 25 percent per year over four years with
the first such vesting occurring on the first anniversary of the date of this
Agreement; provided, however, that (i) in the event of the termination of
Executive's employment pursuant to Section 5(b), or (ii) in the event of a
"Change of Control" (as such term is defined in the Restricted Stock Agreement),
or (iii) in the event of the expiration of the Term on December 31, 2010, such
restrictions shall lapse immediately.

        (i)    Years of Service.    For purposes of Executive's participation in
the plans of the Kratos contemplated by Section 4(d), 4(e), 4(f) and 4(g),
Executive's years of service shall include that time prior to the date hereof
during which Executive had been employed by the Company.

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

        (j)    Vehicle Allowance.    Executive shall be entitled to a vehicle
allowance of $250 per pay period.

        (k)   Disability.    If Executive shall become disabled during the Term,
and such Disability shall continue for a period in excess of one month, the
Salary shall be paid to the Executive during the period of such Disability until
the earlier of six (6) calendar months or the date Executive begins receiving
long term disability payments under a long term disability policy provided by
the Company. Any Salary paid to the Executive under this Section shall be
reduced by insurance benefits that the Executive may receive from any disability
insurance purchased on Executive's behalf by the Company. For purposes of this
Agreement, the terms "Disabled" and "Disability" shall be defined as Executive's
inability, because of physical or mental illness or injury or incapacity, to
perform Executive's essential duties, with reasonable accommodation.

        (l)    Bonus Upon Change of Control.    Upon the occurrence of a "Change
of Control" of the Company (as such term is defined in the Restricted Stock Unit
Agreement) at any time during the Term following the Commencement Date, the
Executive shall be paid immediately in cash, a bonus in an amount equal to the
amount of the Executive's then current Salary in addition to other amounts
required to be paid to Executive pursuant to Section 6 hereof, if his position
as President of the Company (or as changed per Section 2 (c) above) or if his
powers, authority, duties or responsibilities are materially diminished during
the remaining period of the Term following the Change of Control. For purposes
of clarification, this Section 4 (l) only applies to a Change of Control of the
Company and not Kratos or KGS.

        5.     Termination.    Subject to the respective continuing obligations
of the parties hereto set forth in Sections 6 and 7 hereof, the Term and
Executive's employment with the Company may be terminated as follows:

        (a)   By the Company for Cause.    The Company may terminate the Term
and Executive's employment with the Company immediately for cause. For purposes
of this Agreement, "for cause" shall mean:

actual financial harm to the Company;

after written notice to Executive identifying such failure with reasonable
specificity;

        (vi)  a willful and material breach of this Agreement by Executive

4

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

       (vii)  any willful violation by Executive in any material respect of any
of the Company's or Kratos' material policies (other than any such violation

identifying such violation with reasonable specificity; or

      (viii)  the willful failure by Executive (other than any such failure
resulting from a disability pursuant to Section 5(d) hereof) to comply with any

purposes of this Agreement, "Good Reason" shall be defined as any breach or
violation by the Company of any material provision or covenant of this Agreement
(including without limitation a diminution of the Executive's powers, authority
or duties under Section 2, as a president of a subsidiary [or otherwise per
Section 2(c) above]), or a relocation of Executive's office other than in
compliance with Section 2(b) which breach has not been cured within thirty
(30) days after written notice to the Company identifying such breach with
reasonable specificity.

        (c)   Death.    The Term and Executive's employment with the Company
shall terminate automatically and immediately in the event of Executive's death.

        (d)   Severance Payment.    In the event this Agreement is not renewed
on or before January 15, 2010, as provided in Section 3 (a) hereof, on terms
substantially similar to those contained in this Agreement, then Executive will
not be required to perform any services for the Company in the third year of
this Agreement, other than those minimal usual and customary for an executive
similarly situated to assist in the transition of duties to a successor. In the
event the Agreement is renewed on or before January 15, 2010, as provided in
Section 3 (a) hereof, on terms and conditions substantially similar to those
contained in this Agreement, but at a term of less than three years, the
subsequent renewal agreement shall provide that, in addition to the other
amounts payable as otherwise provided therein, in the event of the termination
of a shortened term of such renewed agreement and Executive's employment by the
Executive for "Good Reason" (as defined therein) or in the event of the
expiration of the renewed agreement at the end of the shortened term of such
renewed agreement, the Company shall pay the Executive a severance payment equal
to $250,000 payable in twelve (12) equal monthly installments with the first
installment due and payable on the date of termination of the Executive's
employment ("Severance Payment"). If the Executive and the Company agree at or
before January 15, 2010 that the Executive shall continue to work in full
performance of this Agreement through the end of 2010, then Executive shall be
entitled to the Severance Payment during 2011.

        (e)   No Mitigation; Exclusive Remedy.    Executive shall not be
required to mitigate the amount of any payment provided for in this Section 6 by
seeking other employment or otherwise, nor shall the amount of any payment
provided for in this Section 6 be reduced by any compensation earned by
Executive as the result of employment by another company or business or by
profits earned by Executive from any other source at any time before and after
the Date of Termination. The payments provided under this Section 6 upon
termination shall be in lieu of any other payments or damages recoverable in any
causes of action by Executive related to this Agreement.

        7.     Non-Competition and Non-Solicitation.

        (a)   Subject to the terms and conditions hereof, Executive covenants
and agrees that, for the Restricted Period and in the Restricted Territory (as
defined below), Executive shall not, either directly or indirectly, through an
affiliated or controlled entity or person, on his own behalf or as a

6

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

partner, director, consultant, proprietor, principal, agent, creditor, security
holder, trustee or otherwise (except by ownership of five percent (5%) or less
of the outstanding stock of any publicly held corporation) or in any other
capacity, own, manage, operate, finance, control, invest, participate or engage
in, lend his name to, lend credit to, render services or advice to, or devote
any material endeavor or effort to a venture or business that is engaged in a
business substantially similar to the Restricted Business.

        (b)   The "Restricted Territory" shall be the United States of America.
The "Restricted Period" as used in this Agreement shall be; through the three
(3) year Term of this Agreement; and/or through the Term of any renewal of this
Agreement; and/or through the final payment of the Severance Payment per
Section 6(d) hereof. Therefore, if, for example the Executive leaves the Company
for any reason during the initial three year Term of this Agreement, whether it
is voluntarily, involuntarily or for Good Cause, he shall be bound by the terms
of Sections 7, 8 and 9 through the end of the three year period. If the
Executive leaves the Company for any reason during any renewal of the agreement
he shall be bound by the terms of Sections 7, 8, and 9 though the end of the
renewal term; and he shall be bound by Sections 7, 8, and 9 during any period
where he receives a Severance Payment. "Restricted Business" means that any
business, operations or planned businesses or lines of business engaged in or
planned by Kratos, KGS, the Company or any affiliates or subsidiaries thereof at
the termination of the Executive's active employment. A planned business or
lines of business shall mean a material and significant level of investment and
planning and preparation, as to which the Executive has knowledge, to enter into
the subject business or lines of business.

        (c)   The covenants contained in this Section 7 shall be construed as if
each covenant is divided into separate and distinct covenants in respect of the
Restricted Business, each capacity in which Executive is prohibited from
competing and each part of the Restricted Territory in which the Company is
carrying on the Restricted Business. Each such covenant shall constitute
separate and several covenants distinct from all other such covenants.

        (d)   Each of the parties recognizes that the territorial restrictions
contained in this Agreement are properly required for the adequate protection of
the Restricted Business and that in the event any covenant or other provision
contained herein shall be deemed to be illegal, unenforceable or unreasonable by
a court or other tribunal of competent jurisdiction with respect to any part of
the Restricted Territory, such covenant or provision shall not be affected with
respect to any other part of the Restricted Territory, and each of the parties
agrees and submits to the reduction of said territorial restriction to such an
area as said court shall deem reasonable.

        8.     Noninterference with Business.

        (a)   During the Restricted Period, Executive agrees not to (a) directly
or indirectly contact any of the Company's, Kratos' or KGS' then current
customers or prospective customers with whom the Company, Kratos or KGS is
engaged in discussions or proposal negotiations ("Prospective Customers") for
the purpose of diverting or taking away from the Company, Kratos or KGS any
business existing as of the date of the termination of Executive's employment
with the Company, Kratos or KGS; or (b) otherwise interfere with, impair or
damage the Company's, Kratos' or KGS' relationship with any of its then current
or Prospective Customers.

        (b)   During the Restricted Period, Executive agrees not to knowingly
directly or indirectly solicit, whether for his own benefit or for that of
another, induce or attempt to induce any employee, consultant or independent
contractor to terminate or breach an employment, contractual or other
relationship with the Company, Kratos or KGS.

        9.     Non Disparagement.    Executive expressly agrees that during his
employment with the Company and for two (2) years following the termination of
such employment for any reason, he will make no

7

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

statement and take no actions of any kind, verbal or written, that directly or
indirectly disparage, the Company, Kratos or KGS, or any affiliates or related
parties, to any of their respective employees, customers or vendors, or
interferes with the Company's or affiliates operations.

        10.   Proprietary Matter; Ownership.    Except as permitted or directed
by the Company or as required by law, Executive shall not during the term of his
employment or at any time thereafter knowingly divulge, furnish, disclose or
make accessible (other than in the ordinary course of the business of the
Company) to anyone for use in any way any confidential, secret, or proprietary
knowledge or information of the Company or its affiliates that is not in the
public domain ("Proprietary Matter") which Executive has acquired or become
acquainted with or will acquire or become acquainted with during his employment,
whether developed by himself or by others, including, but not limited to, any
trade secrets, confidential or secret designs, processes, formulae, software or
computer programs, plans, devices, or material (whether or not patented or
patentable, copyrighted or copyrightable) directly or indirectly useful in any
aspect of the business of the Company and its affiliates, any confidential
customer, distributor or supplier lists of the Company or its affiliates, any
confidential or secret development or research work of the Company or its
affiliates, or other confidential, secret or non-public aspects of the business
of the Company or its affiliates. Executive acknowledges that the Proprietary
Matter constitutes a unique and valuable asset of the Company or its affiliate,
acquired at great time and expense by the Company or such Affiliate, and that
any disclosure or other use of the Proprietary Matter other than for the sole
benefit of the Company or such affiliate would be wrongful and could cause
irreparable harm to the Company or such affiliate. The foregoing obligations of
confidentiality, however, shall not apply to any knowledge or information which
is now published or which subsequently becomes generally publicly known, other
than as a direct or indirect result of the breach of this Agreement by
Executive.

        Executive agrees that he will fully inform and disclose to the Company
from time to time all inventions, designs, improvements, enhancements,
developments and discoveries which he now has, or may hereafter have, during the
Term which pertain or relate to the business of the Company or to any
experimental work carried on by the Company or its affiliates. All such
inventions, designs, improvements, enhancements, developments and discoveries
shall be the exclusive property of the Company or its affiliates. At the
Company's sole cost and expense, the Executive shall reasonably assist the
Company or its affiliates in obtaining patents on all such inventions, designs,
improvements, enhancements, developments and discoveries deemed patentable by
the Company or its affiliates and shall execute all documents (including
assignments and related affidavits) and do all things reasonably necessary to
obtain such patents. This provision shall not apply to any inventions for which
no equipment, supplies, facilities or trade secret information of the Company or
its affiliates was used and which was developed on Executive's own time without
using any of the Company's or its affiliates' equipment, supplies, facilities or
trade secret information, except for those inventions which either: (a) related
at the time of conception or reduction to practice of the invention to the
Company or its affiliates business, or actual or demonstrably anticipated
research or development of the Company or its affiliates, or (b) result from any
work performed by Executive for the Company or its affiliates.

        This Section 10 supplements any existing agreement between the Company
and Executive relating to the subject matter set forth in this Section 10. In no
event shall this Section 10 be deemed to limit the rights of the Company
contained in any such existing agreement.

        Upon termination of his employment for any reason, Executive shall
deliver promptly to the Company all records, manuals, books, blank forms,
documents, letters, memoranda, notes, notebooks, reports, data, tables, and
calculations or copies thereof, which are the property of the Company and which
relate in any way to the business, products, practices or techniques of the
Company, and all other property of the Company and Proprietary Matter,
including, but not limited to, all documents which in whole or in part, contain
any trade secrets or confidential information of the Company, which in any of
these cases are in his possession or under his control. If Executive purchases
any record book,

8

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

ledger, or similar item to be used for keeping records of or information
regarding the business of the Company or its customers, Executive shall
immediately notify the Company, which shall then immediately reimburse Executive
for the expense of such purchase.

        11.   Injunctive Relief.    Executive agrees that it would be difficult
to compensate the Company fully for damages for any violation of the provisions
of this Agreement, including, without limitation, the provisions of Sections 7,
8, 9, and 10. Accordingly, Executive specifically agrees that the Company shall

provisions, contained in this Agreement shall for any reason be held to be

provision or part hereof. Specifically, but without limiting the foregoing in
any way, each of the covenants of the parties to this Agreement contained herein
shall be deemed and shall be construed as a separate and independent covenant
and should any part or provision of any such covenants be held or declared
invalid by any court of competent jurisdiction, such invalidity shall in no way
render invalid or unenforceable any other part or provision thereof or any other
covenant of the parties not held or declared invalid.

Conduct, attached hereto as Exhibit B, concurrently with the execution of this
