1. Duties and Scope of Employment.

(a) Positions and Duties. As of the Effective Date, Employee will serve as the Chief Executive Officer of the Company. Employee will render such business and professional services in the performance of his duties, consistent with Employee’s position within the Company, as shall reasonably be assigned to him by the Company’s Board of Directors (the “Board”). The Board shall in its sole discretion, have the right at any time to remove the Employee from his position as Chief Executive Officer of the Company and in such event the Board shall, after consultation with the Employee, reasonably determine the Employee’s new title and responsibilities and to whom the Employee will report; provided, further, that in the event of any such changes, Employee’s compensation and benefits shall remain unchanged and the geographic location of Employee’s employment may be changed to within 50 miles of his then current employment, and that the Employee’s position shall be at the executive management level, subject to the right under this Agreement of the Employee or the Company to terminate Employee’s employment at any time. If the Employee is elected or appointed to be a director or officer of the Company or any Subsidiary during the term of this Agreement, he shall serve in such capacity or capacities without additional compensation. The period of Employee’s employment under this Agreement is referred to herein as the “Employment Term.”

For the duration of the Employment Term, and except with respect to those organizations and businesses listed on Exhibit B, Employee agrees not to actively engage in any other employment, occupation or consulting activity for any direct or indirect remuneration without the prior written approval of the Board. The parties agree that Employee may serve as an employee, officer and/or director of ICx Technologies, Inc. and any or all of its Affiliates.

2. At Will Employment. The parties agree that Employee’s employment with the Company will be “at will” employment and may be terminated at any time with or without cause or notice. Employee understands and agrees that neither his job performance nor promotions, commendations, bonuses or the like from the Company give rise to or in any way serve as the basis for modification, amendment, or extension, by implication or otherwise, of his employment with the Company.

3. Confidentiality. Employee agrees to execute and comply with the terms and conditions of the ICx Technologies, Inc. At Will Employment, Confidential Information, Non-Competition, and Invention Assignment Agreement, a copy of which is attached as Exhibit A and is incorporated by this reference.

4. Compensation.

(a) Base Salary. During the Employment Term, the Company will pay Employee as compensation for his services a base salary at the annualized rate effective as of the date of this Agreement (the “Base Salary”). The Base Salary will be reviewed periodically at intervals not less frequently than annually by the Board of Directors (or the Compensation Committee of the Board of Directors) of the Company for the purpose of considering increases thereof. The Base Salary will be paid periodically in accordance with the Company’s normal payroll practices and be subject to the usual, required withholding.

(b) Bonus. Subject to the achievement of certain reasonable objectives that the Compensation Committee of the Board may establish, the Employee shall be eligible to receive an annual cash bonus (“Bonus”) which shall be determined by the Board of Directors (or the Compensation Committee) of the Board of Directors of the Company in its sole discretion. The Company shall have the right to condition the payment of each Bonus on the Employee signing a document reasonably acceptable to the Company pursuant to which the Employee confirms, ratifies and agrees that this Agreement, and the ICx Technologies, Inc. At Will Employment, Confidential Information, Non-Competition, and Invention Assignment; and all of its provisions are valid and binding and are enforceable against the Employee in accordance with their terms. Employee may also serve as a director, officer and/or employee of ICx Technologies, Inc. and/or any of its Affiliates (collectively, “ICx”) and shall be entitled to receive such bonus and other compensation and perquisites as ICx may determine.

(c) Stock Options. Employee shall be eligible to receive options from time to time during the term of this Agreement as provided by the Board, in its sole discretion. Each such option granted to Employee shall provide, among other things, that in the event Employee’s employment hereunder is terminated other than for Cause, or by death or Disability, the right to exercise such option shall become fully vested as of the date of such termination event.

(d) Life Insurance. During the term of Employee’s employment hereunder, the Company shall, at the Company’s cost, continue to maintain in full force and effect life insurance insuring the life of the Employee under Policy No. 15-615-414 in the face amount of $1,500,000 issued by Northwestern Mutual and under Policy No. FK3322090 in the face amount of $2,000,000 issued by Zurich/Chase, and Employee shall retain all rights to designate the beneficiary or beneficiaries under each such policy. Any and all proceeds payable under the terms of each such policy shall be payable to such persons and in accordance with Employee’s designation. Upon the termination of Employee’s employment hereunder for any reason, Employee shall have the option and right, subject to agreement by the insurance underwriter, to assume ownership of each such policy and, upon Employee’s request, the Company will assign all rights, titles and interests in and under each such policy to Employee or Employee’s designee. The life insurance to be provided under this sub-section (d) is in addition to the insurance coverage required by the Acquisition Agreement.

5. Employee Benefits. During the Employment Term, Employee will be entitled to participate in the employee benefit plans currently and hereafter maintained by the Company of general applicability to other comparable employees of the Company. The Company reserves the right to cancel or change the benefit plans and programs it offers to its employees at any time.

6. Vacation. Employee will be entitled to paid vacation of three weeks per year in accordance with the Company’s vacation policy, with the timing and duration of specific vacations mutually and reasonably agreed to by the parties hereto.

The Company will reimburse Employee for reasonable travel, entertainment or other expenses incurred by Employee in the furtherance of or in connection with the performance of Employee’s duties hereunder, in accordance with the Company’s expense reimbursement policy as in effect from time to time.

In addition, the following will apply:

(a) Involuntary Termination. If the Company terminates Employee’s employment with the Company for reasons other than Cause, or by reason of Employee’s death or Disability, then, subject to Employee’s compliance with Section 8(d), Employee shall be entitled to receive:

(i) Accrued Obligations; and

(ii) Continuing payments of severance pay (less applicable withholding taxes) at a rate equal to his Base Salary rate, as then in effect, for a period of twelve (12) months from the date of such termination (herein after the “Severance Term”), to be paid periodically in accordance with the Company’s normal payroll policies, provided that the Company shall, in its sole discretion, have the right to extend the length of the Severance Term for up to an additional twelve (12) months at its choosing (such extended period being referred to as the “Extended Severance Term”) in which case (a) the severance pay to be paid to Employee during the Extended Severance Period shall be 200% of the rate of severance pay during the Severance Term, and (b) the length of the Noncompete Period, as defined in the ICx Technologies, Inc. At Will Employment, Confidential Information, Non-Competition, and Invention Assignment Agreement, shall be commensurately extended. For the avoidance of doubt, if the Company elects to extend the length of the Severance Term by three months, the length of the Noncompete Period, as defined in the ICx Technologies, Inc. At Will Employment, Confidential Information, Non-Competition, and Invention Assignment Agreement, shall be extended by three months.

The Employee’s employment shall terminate upon his Disability and upon such event, the Employee shall be entitled to receive the Accrued Obligations.
