Susan M. Simmons

COO, Cartesian, Inc.

Dear Ms. Simmons:

This Separation Agreement (the “Agreement”) is entered into by and between you and Cartesian, Inc. (the “Company”), and confirms the agreement that has been reached with you in connection with your separation from employment as the Company's Chief Operating Officer. In consideration of the promises and the mutual covenants set forth herein, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties, intending to be legally bound, hereby agree as follows:

ARTICLE I. SEPARATION FROM EMPLOYMENT

1.1           Transition. Your employment with the Company as its Chief Operating Officer as well as all positions with the Company's affiliates as an employee or officer will sever effective October 2, 2015 ("Separation Date").

1.2           Payments and Benefits. In consideration of your execution of this Agreement and your compliance with its terms and conditions, the Company agrees to pay or provide to you, subject to the terms and conditions set forth in this Agreement, with the benefits described in this Section 1.2. You acknowledge and agree that the benefits below shall be in full satisfaction of your obligations and the Company's obligations under the terms of your employment agreement entered into with the Company on October 20, 2006 and all applicable cash or equity incentive compensation plans and agreements.

As of the Separation Date, the Company will pay you:

(c)          Separation Payment. The total gross sum of three hundred and five thousand dollars ($305,000.00), less appropriate payroll deductions, payable in installments as follows: (i) $40,000 payable ten days following the signing of this agreement (ii) $100,000 payable October 23^rd, (iii) $100,000 payable November 20^th, and (iv) $65,000 payable December 18^th, provided you execute and return this Agreement, and have not revoked this Agreement pursuant to the terms of Section 2.2 of this Agreement.

In addition to the above, the Company will also provide the following benefits:

(d)          Accrued Vacation. As of the Separation Date, the Company will pay you the balance of any vacation days accrued but not yet taken as of the Separation Date in accordance with the Company's vacation cash-out policy, minus withholdings as required by law. Payment of this amount is not contingent upon your signing this Agreement.

(e)          Benefits. The Company will provide you with separate written notification of your right to continue coverage under the Company's group medical, dental, and vision insurance plans under COBRA, 29 U.S.C. §1161 et seq. Other than your right to receive the Company’s 401(k) matching benefit, your right to continued participation in all other of the Company's benefit plans shall cease on the Separation Date; provided, however, that any accrued benefit you have under the Company's 401(k) retirement plan shall be paid in accordance with the terms of such plan. To the extent permitted by applicable law and without subjecting the Company to any fines, penalty or excise taxes, the Company will pay the premium for any COBRA benefits you elect through the Company for a period of nine (9) months from the Separation Date. If a change in the law prevents the Company from paying your COBRA premiums directly to the insurer, then the Company will pay the cash value of any remaining COBRA premium payments to you on an after-tax basis. Each monthly payment for COBRA coverage will be paid only so long as you or any of your dependents elect to continue health care coverage pursuant to COBRA.

1.3           Forfeiture of All Unvested Equity Awards. As of the Separation Date all unvested awards under the Company's 1998 Equity Incentive Plan ("Equity Plan") shall be forfeited and expire notwithstanding any contrary terms set forth in any employment agreement, award agreement or the Equity Plan.

1.4           Unemployment Compensation. The Company will not file a written protest to any claim for unemployment compensation benefits that you may file with the Commonwealth of Massachusetts; however, the Company will report any wages or separation payments as required by Massachusetts law.

ARTICLE II. OTHER AGREEMENTS

2.1           General Release. In exchange for the promises set forth herein, the sufficiency of which you hereby acknowledge, you, on behalf of yourself, your heirs, executors, representatives, successors, administrators and assigns, and anyone claiming by, through or for you, or anyone making a claim on your behalf, to irrevocably and unconditionally waive, release and forever discharge the Company, and its present, past, and future parents, subsidiaries, and affiliated corporations, divisions, affiliates, predecessors, principals, partners, joint venturers, representatives, successors, and assigns, and their past and present owners, directors, officers, employees, stockholders, attorneys, agents, and insurers, and all persons acting by, through, under or in concert with any of them and all other persons, firms and corporations whomsoever in their individual, corporate, or official capacities (collectively “Released Parties”), from any and all liability, actions, causes of actions, common law claims, statutory claims under state or federal law including any rights and claims under Title VII of the Civil Rights Act of 1964, as amended, the Equal Pay Act, the Employee Retirement Income Security Act, COBRA, the Americans with Disabilities Act, the Family & Medical Leave Act, the Age Discrimination in Employment Act, the Worker Adjustment and Retraining Notification Act (“WARN”), the Massachusetts Fair Employment Practices Law,  M.G.L. c. 151B; the Massachusetts Civil Rights Act, M.G.L. c. 12 §11H et seq., the Massachusetts Equal Rights Act, M.G.L. c. 93 § 102 et seq., the Massachusetts Privacy Statute, M.G.L. c. 214 §1B; the Massachusetts Sexual Harassment Statute, M.G.L. c. 214 §1C; the Massachusetts Wage Act, M.G.L. ch. 149 §§ 148, 150 et seq.; the Massachusetts Minimum Fair Wage Law, M.G.L. ch. 151; any claims that may be released under Massachusetts labor statutes, M.G.L. c. 149, any other state’s human rights act, wage payment act, civil rights laws, or similar laws, any law governing any aspect of employment, and any amendments thereto, any claim under any state or federal common law, statute, regulation or ordinance, breach of contract claims, retaliation claims, tort claims, state law public policy claims, breach of any collective bargaining agreement claims, and all demands, damages expenses, fees (including attorney’s fees, court costs, expert witness fees, etc.), which Employee may now or hereafter have against the Released Parties and/or have on account of, arising out of, or in connection with all interactions, transactions or contracts, express or implied, between Employee and the Released Parties, including, but not limited to Employee’s employment and the termination thereof, or any acts, transactions, or occurrences between the Employee and the Released Parties through the date of this Agreement.

Without waiving any prospective or retrospective rights under the Fair Labor Standards Act (“FLSA”) or Family and Medical Leave Act (“FMLA”) and/or any equivalent state law, Employee admits that Employee has received from the Company all rights and benefits, if any, potentially due to Employee pursuant to the FLSA, FMLA, and/or any other relevant laws. It is the parties’ intent to release all claims which can legally be released, as such, this release does not apply to those claims which as a matter of law cannot be released. Employee states that Employee is aware of no facts (including any injuries or illnesses) which might lead to Employee's filing of a workers’ compensation claim against the Released Parties, and Employee warrants and agrees that Employee has not suffered any work injury that Employee has not previously disclosed to the Company.

Nothing in this Agreement shall limit or impede Employee’s right to enforce the provisions of this Agreement, or of any consulting agreement that is executed contemporaneously with the Agreement; to obtain indemnity as an officer or director pursuant to the Company’s organizational documents or bylaws or under any applicable policy of insurance; to file or pursue an administrative charge with, or participate in, any investigation before the Equal Employment Opportunity Commission or any Federal, State, or Local Agency; to file a claim for unemployment benefits; to file a claim asserting any causes of action which by law Employee may not legally waive; or to report possible violations of federal law or regulation to any governmental agency or entity, including but not limited to the Department of Justice, the Securities and Exchange Commission, Congress, and any agency Inspector General, or make other disclosures that are protected under the whistleblower provisions of federal law or regulation. You agree, however, that if you or anyone on your behalf brings any action concerning or related to any cause of action or liability released in this Agreement, you waive your right to, and will not accept, any payments, monies, damages, or other relief, awarded in connection therewith.  Additionally, nothing in this Agreement shall be interpreted or applied in a manner that affects or limits Employee’s ability to challenge this Agreement’s compliance with notice and other requirements of the Age Discrimination in Employment Act and/or the Older Workers Benefit Protection Act.
