Exhibit 10.2

EMPLOYMENT AGREEMENT

This EMPLOYMENT AGREEMENT, (the “Agreement”) dated this 26th day of March, 2010 is made by and between Global Defense Technology & Systems, Inc., a Delaware corporation (“GTEC”) and Global Strategies Group (North America) Inc., a Maryland corporation (“GNA”, with GTEC and the Company referred to as the “Company”), and James Allen (the “Executive”).

WHEREAS, the GNA and the Executive previously entered into an Employment Agreement effective of May 18, 2009, as subsequently amended (the “Prior Agreement”); and

WHEREAS the Company and the Executive desire to amend and restate the terms of the Prior Agreement.

In consideration of the foregoing and the covenants below, the Company and Executive agree as follows:

(a) During the Term (as defined in Section 2 hereof), GNA shall employ Executive and Executive shall render services to GNA and GTEC as the Executive Vice President and Chief Financial Officer. Executive shall perform during his employment with GNA such duties and exercise such powers in relation to the business of the Company commensurate with his positions with the Company.

(b) During the Term, Executive shall report to John Hillen, III, President and Chief Executive Office (referred to as the “CEO”).

(c) Executive shall perform such actions consistent with his position and such other duties as may from time to time be assigned to him by the President and CEO. In the performance of his duties, Executive shall comply with such limits on Executive’s authority in his positions with the Company as the CEO and Board may from time to time impose. Executive shall devote his full and exclusive business time and best efforts to the performance of his duties under this Agreement and shall perform them faithfully and diligently; provided that Executive may (i) serve on civic, charitable or, with the Board’s consent, corporate boards or committees and (ii) deliver lectures, fulfill speaking engagements or teach at educational institutions and retain any remuneration received therefore as long as such activities do not, in the Board’s judgment, interfere with the performance of his duties hereunder. The Executive may also continue to serve on the board of directors and boards of advisors listed on Appendix A. For any full day commitment by the Executive required to perform the services on Appendix A, Executive shall be treated as having taken leave without pay for such day.

The Executive’s employment with GNA commenced on May 18, 2009 under the terms of the Prior Agreement (the “Original Effective Date”). Pursuant to the terms of the Prior Agreement, the term of Executive’s employment is currently extended until May 18, 2010 (the “Initial Expiration Date”). Subject to the provisions of this Section 2 and earlier termination pursuant to Section 4 below, the term of

this Agreement shall end on the Initial Expiration Date, provided that, subject to earlier termination pursuant to Section 4 below, commencing on the Initial Expiration Date, and on each anniversary of the Initial Expiration Date thereafter, the term of this Agreement shall automatically be extended for an additional year unless, not later than six (6) months prior to the expiration of the then-existing term, the Company or the Executive shall have given notice not to extend the term of this Agreement; and provided, further, that if a Change of Control (as defined herein) of GTEC shall have occurred during the original or any extended term of the Executive’s employment pursuant to this Agreement, the term of the Executive’s employment pursuant to this Agreement shall continue in effect for a period of twelve (12) months from the date on which such Change of Control occurred. All periods during which the Executive is employed hereunder shall hereinafter be referred to as the “Term.”

(a) Salary. As full compensation for Executive’s services under this Agreement, Executive shall be entitled to an annual gross salary at the rate of $300,000 US Dollars (“Base Salary”). The Base Salary shall be payable in accordance with the Company’s normal payroll practices. If Executive’s employment begins or terminates part way through a payment period, his Base Salary will be prorated based on the actual number of days included in the period. All forms of compensation referred to in this Agreement are subject to applicable withholding and payroll taxes. The Base Salary may be increased from time to time at the discretion of the CEO and Board.

(b) Bonus. In addition to his Base Salary, Executive will also be considered for an annual bonus with a performance-based target of 50% of the Base Salary (the “Target Bonus Amount”). Performance objectives for Company’s financial year (“Financial Year”) will be determined by the CEO and Board or a committee thereof generally during the first ninety (90) days of the Financial Year. The actual amount of any bonus shall be determined in the sole discretion of the Board. Receipt by Executive of a bonus in relation to any Financial Year is not to be regarded as establishing an entitlement on the part of Executive to receive a bonus in relation to subsequent Financial Years or as to the amount of any such bonus. Bonuses are subject to Executive still being employed by the Company at the date payment is due and to his not being under notice of termination on that date either given by Executive or the Company. The Target Bonus Amount may be increased from time to time at the discretion of the CEO and Board.

(c) Equity Compensation.

(i) Grants. The Executive will be eligible for stock option grants “Options” in the sole discretion of the CEO and Board taking into account the Executive’s performance, the performance of the Company and other factors the Board determines to be relevant. The exercise price of any grants of Options shall be the fair market value of the underlying shares on the date of grant, as determined by the Board in accordance with the terms of the Plan and each Option shall vest as provided by the Board at the time of grant.

(ii) Accelerated Vesting. Notwithstanding anything herein to the contrary, in the event of a Change in Control (as defined below), if the Executive’s Options are assumed or continued by the GTEC or its successor entity, including the parent of the GTEC or its successor, in the sole discretion of the parties to the Change in Control transaction and thereafter remain in effect following such Change in Control, then all Options held by the Executive shall be deemed

vested and exercisable in full as of immediately prior to the date on which the Executive’s employment with the Company and its subsidiaries or successor entity terminates if (i) such termination occurs within six (6) months following such Change in Control and (ii) such termination is either by the Company (or successor entity) without Cause or by the Executive for Good Reason. If, following a Change in Control, to the extent that Options are not assumed or continued by the GTEC or its successor entity, including the parent of the GTEC or its successor, then, subject to the Executive’s continued employment with the GTEC through the date of the Change of Control, vesting of such outstanding Options will accelerate to 100% as of immediately prior to the effective date of the Change in Control. All Options will cease to vest upon death, disability or termination of employment.

(a) General. Notwithstanding Section 2 above, the Company may terminate Executive’s employment prior to expiration of the Term for any of the following reasons: (i) as a result of his death or Disability as provided in Section 4(b) below, (ii) for Cause as provided in Section 4(c) below or (iii) without Cause as provided in Section 4(d) below.

(b) Termination due to Death; Disability. The Term shall terminate on Executive’s death or Disability, at which time the Company’s obligations under this Agreement to pay further compensation shall cease forthwith, except that the Company shall pay Executive (or his estate or legal representative, as the case may be), in full and complete satisfaction of all of the Company’s obligations under this Agreement, the following: (i) any accrued but unpaid Base Salary prorated on a daily basis up to the date of such termination; (ii) subject to submission of all required documentation, reimbursable expenses accrued (but unpaid) as of the date of such termination of the Executive’s employment; (iii) any accrued but unused vacation days paid at a rate determined consistently with Company policy; and (iv) any vested and accrued employee benefits payable under the Company’s employee benefit plans (collectively, the “Accrued Rights”). As used in this Agreement, the term “Disability” shall mean a physical or mental disability or incapacity of Executive, whether total or partial, that, in the good faith determination of the Board, has prevented him from performing substantially all of his duties under this Agreement during a period of two consecutive months or for one hundred eighty (180) days during any twelve (12) month period (or such longer period as may be required to comply with applicable law).

(c) Termination for Cause. If Executive (i) willfully fails to perform his duties hereunder in a material manner and such failure shall not be discontinued promptly after written notice to Executive thereof (which notice shall be signed by the CEO and Board or a designated officer of the Company and refer to a breach of the Employment Agreement); (ii) is charged with or indicted for a felony or other crime casting doubt on Executive’s trustworthiness or integrity; (iii) (A) materially breaches any of his covenants under Sections 5(a) through 5(d) hereof or (B) knowingly and materially breaches any of his covenants under Section 5(e) hereof; (iv) commits any act of dishonesty that is intended to result in personal enrichment of the Executive at the expense of the Company or (v) in bad faith, commits any act or omits to take any action, to the material detriment of the Company (each of the foregoing (i)—(v) constituting “Cause”); then the Company may at any time by written notice terminate Executive’s employment and the Term, and Executive shall have no right to receive any compensation or benefit from the Company hereunder on and after the effective date of such notice, except for any Accrued Rights.

(d) Termination Without Cause. Notwithstanding anything to the contrary contained elsewhere in this Agreement, the Company, in the sole discretion of the CEO and Board, shall have the right to terminate Executive’s employment during the Term at any time and for any reason, without Cause by written notice to Executive. In the event that Executive’s employment is terminated without Cause, then, provided the Executive has incurred a “separation from service” within the meaning of Section 409A of the Code and applicable Treasury Regulations (a “Separation from Service”), and subject to the Executive’s execution and non-revocation of an effective general release of claims in favor of the Company in a form delivered by the Company to the Executive within the applicable consideration period specified in the release (not to exceed thirty (30) days following such delivery) (which delivery will be made within seven days following Executive’s Separation from Service with the Company), the Company shall pay Executive as severance an aggregate amount equal to:

(i) Six (6) months of his Base Salary (or twelve (12) months of his Base Salary if such termination of employment occurs within six (6) months following a Change in Control);

(ii) notwithstanding the requirement of Section 3(b) that the Executive be employed on the bonus payment date, the amount of any unpaid bonus which has been earned by the Executive for any Financial Year preceding the termination of the Executive’s employment in respect of which such compensation is paid or payable;

(iii) 50% of the Target Bonus Amount for the Financial Year during which the termination occurs (or 100% of the Target Bonus Amount if such termination of employment occurs within six (6) months following a Change in Control).

All payments due under this Section 4(d) are subject to Section 7(k). Subject to the other terms of this paragraph, his severance shall be payable as and when Executive’s Base salary or bonus would otherwise have been paid (and in the case of Base Salary, in accordance with the Company’s regular payroll payment practices) but in the case of the bonus amount, no later than March 15 of the year following the year during which the Executive is notified of his termination from the Company with the date of such payment determined by the Company. Notwithstanding the foregoing sentence, if the Executive incurs a Separation from Service within two (2) years following the occurrence of a Change in Control that also constitutes a change in the ownership or effective control of GTEC or a change in the ownership of a substantial portion of the assets of GTEC, in all cases within the meaning of Treasury Regulation Section 1.409A-3(i)(5), severance payments to which the Executive is entitled under this Section 4(d) shall, except as limited below, be paid in a single lump sum on the First Payment Date (as defined below). In the event of a Separation from Service prior to August 18, 2011 (the expiration date of the term of the Prior Agreement in effect on the date of this amended and restated Employment Agreement), the Change in Control lump-sum payment rule shall not apply to any amount which would be treated as nonqualified deferred compensation (within the meaning of Section 409A of the Code) under the Prior Agreement as in effect immediately prior to this amended and restated employment agreement and any such amount of nonqualified deferred compensation shall be paid in accordance with the rules of the second sentence of this paragraph. Notwithstanding any provision of this Agreement to the contrary, no severance payments otherwise payable under this Section 4 shall be paid prior to the 60^th day following the date of the Executive’s Separation from Service with the Company (the “First Payment Date”) and any such amounts that otherwise would have been paid prior to the First Payment Date shall be paid on the First Payment Date. The Company shall have no other liability to Executive other than for the

Accrued Rights or as otherwise required by law. Notwithstanding the foregoing provisions of this Section 4(d), the payments described in this Section 4(d) shall immediately cease and be irrevocably forfeited if the Executive violates any of the restrictive covenants contained in Section 5 of this Agreement.

(e) Termination By Executive For Good Reason. If Executive terminates his employment for Good Reason then such termination shall be treated as a termination of Executive’s employment by the Company without Cause under Section 4(d) of this Agreement. For purposes of this Agreement, “Good Reason” shall mean (A) the assignment to Executive of any duties materially and adversely inconsistent with his position as set forth in Section l(a) of this Agreement including, but not limited to status, office or responsibilities as contemplated under Section 1 herein, (B) a change in the Executive’s reporting relationship such that he no longer reports directly to the CEO and Board, (C) a material breach by the Company of any material provision of this Agreement, or (D) the relocation of the Executive’s office as assigned to him by the Company to a location more than fifty (50) miles from the Executive’s office prior to the date of such relocation, except for travel reasonably required in the performance of Executive’s Responsibilities. The Executive must notify the Company in writing of the existence of a condition constituting Good Reason within ninety (90) days of the first occurrence of the condition and the Company shall have thirty (30) days thereafter during which to cure such event. Executive shall not be entitled to resign for Good Reason during such thirty (30) day period or in the event such condition is cured. Executive’s resignation for Good Reason must be effective no later than one hundred eighty (180) days following the first occurrence of a condition constituting Good Reason.

(f) Other Terminations By Executive. During the Term, Executive may in his discretion without Good Reason terminate his employment with the Company by giving the Company at least ninety (90) days written notice of his decision to terminate his employment (or thirty (30) days if the Executive is terminating his employment in order to accept a position with the U.S. Government).

(g) Cooperation. Executive agrees that following any termination of his employment, he shall co-operate with the Company in winding up or transferring to other Executives or members of the Board of the Company or such other individuals as may be directed by the Board of any pending work and shall also co-operate with the Company (to the extent allowed by law and at the Company’s expense) in connection with any action (i) brought by any third party against the Company or (ii) brought by the Company against any third party, in either case that relates to Executive’s duties; provided that such cooperation does not unreasonably interfere with Executive’s subsequent employment. The Company and Executive agree that their obligations under this Section 4(g) shall survive the termination of the Term.

(h) For purposes of this Agreement, “Change in Control” means the occurrence of either of the following:

(i) the acquisition of more than 50% of the combined voting power of GTEC’s then total outstanding voting securities by any “person” or related “group” of “persons” (as such terms are used in Sections 13(d) and 14(d)(2) of the Securities Exchange Act of 1934, as amended) other than (x) GTEC or any affiliate of GTEC, (y) any employee benefit plan of GTEC or any trustee or other fiduciary holding securities under an employee benefit plan of GTEC (or its subsidiaries), or (z) Contego Systems LLC, Kende Holding kft, Global Strategies Group Holding S.A., or any of their affiliates or successor entities (any such person or group an “Acquiring Person”); or

(iii) the stockholders of GTEC approve a plan of complete liquidation or dissolution.

(a) Non-Competition.

Executive’s performance of the services listed on Appendix A as permitted by Section 1(c) shall not be treated as a violation of the Section 5(a).
