CHANGE IN CONTROL

SEVERANCE AGREEMENT

This Agreement between Linda M. McKnight ("you") and VERSAR, INC. ("Company") has been entered into as of September 13, 2013. This Agreement promises you severance benefits if, following a Change of Control, you are terminated without Cause or resign for Good Reason during the Term of this Agreement. Capitalized terms are defined in the last section of this Agreement.

1. Purpose

The Company considers a sound and vital management team to be essential. Management personnel who become concerned about the possibility that the Company may undergo a Change in Control may terminate employment or become distracted. Accordingly, the Company’s Board of Directors (the “Board”) has determined that it is in the best interests of the Company to enter in to this Agreement with You.

2. Events That Trigger Severance Benefits

a. Termination After a Change in Control

You will receive Severance Benefits under this Agreement if, during the Term of this Agreement and after a Change in Control has occurred, your employment is terminated by the Company without Cause (other than on account of your Disability or death) or you resign for Good Reason.

b. Termination After a Potential Change in Control

You will receive Severance Benefits under this Agreement if, during the Term of this Agreement and after a Potential Change in Control has occurred but before a Change in Control actually occurs, your employment is terminated by the Company without Cause or you resign for Good Reason, but only if either: (i) you are terminated at the direction of a Person who has entered into an agreement with the Company that will result in a Change in Control; or (ii) the event constituting Good Reason occurs at the direction of such Person.

c. Successor Fails to Assume This Agreement

You will receive Severance Benefits under this Agreement if, during the Term of this Agreement, a successor to the Company fails to assume this Agreement, as provided in Section 12(a).

3. Events That Do Not Trigger Severance Benefits

You will not be entitled to Severance Benefits if your employment ends because you are terminated for Cause or on account of Disability or because you resign without Good Reason, retire, or die. Except as provided in Section 2(c), you will not be entitled to Severance Benefits while you remain protected by this Agreement and remain employed by the Company, its affiliates, or their successors.

4. Termination Procedures

If you are terminated by the Company after a Change in Control and during the Term of this Agreement, the Company shall provide you with 30 days' advance written notice of your termination, unless you are being terminated for Cause. The notice will indicate why you are being terminated and will set forth in reasonable detail the facts and circumstances claimed to provide a basis for your termination. If you are being terminated for Cause, your notice of termination will include a copy of a resolution duly adopted by the affirmative vote of not less than 51% of the entire membership of the Board (at a meeting of the Board called and held for the purpose of considering your termination (after reasonable notice to you and an opportunity for you and your counsel to be heard before the Board)) finding that, in the good faith opinion of the Board, Cause for your termination exists and specifying the basis for that opinion in detail. If you are purportedly terminated without the notice required by this Section, your termination shall not be effective.

5. Severance Benefits

a. In General

“Severance Benefits” include all of the benefits set forth in Sections 5(b) through 5(f) of this Agreement.

b. Lump-Sum Payment in Lieu of Future Compensation

In lieu of any further cash compensation for periods after your employment ends, other than cash compensation paid pursuant to any agreement governing the terms of a Change in Control payable to all similarly situated persons, you will be paid a cash lump sum equal to 2 times your annual base salary in effect when your employment ends or, if higher, in effect immediately before the Change in Control, Potential Change in Control, or Good Reason event in connection with which your employment terminated. In addition, and without duplication, you will be paid a cash lump sum equal to 2 times the higher of the aggregate amounts paid to you (if any) under any existing cash bonus, cash incentive and/or non-equity incentive compensation plans in the calendar year preceding the calendar year in which your employment ends or in the calendar year preceding the calendar year in which the Change in Control occurred (or in which the Potential Change in Control occurred, if benefits are payable under Section 2(b) hereof).

c. Incentive Compensation

The Company will pay you a cash lump sum equal to any unpaid incentive compensation (that is not otherwise paid to you) that you have been allocated or awarded under any existing bonus, incentive or other programs for performance adopted by the Company for its executive officers and other key employees and relating to measuring periods completed before you became entitled to Severance Benefits under this Agreement. All unvested options to purchase Company common stock will immediately vest and remain exercisable for the longest period of time permitted under the applicable stock option plan. All unvested restricted stock awards and restricted stock unit awards awarded to you will immediately vest.

g. Medical Benefits

Any additional benefits you are entitled to under the Company’s Retired Officer Medical Benefit Program.

6. Time for Payment

Subject to the provisions of Section 20 hereof, you will be paid your cash Severance Benefits within five (5) days after the day you become entitled to Severance Benefits under this Agreement (the “Severance Date”) (e.g., within five (5) days following your termination of employment). If the amount you are due cannot be finally determined within that period, you will receive the minimum amount to which you are clearly entitled, as estimated in good faith by the Company. The Company will pay the balance you are due (together with interest at the rate provided in Internal Revenue Code Section 1274(b)(2)(B)) as soon as the amount can be determined, but in no event later than thirty (30) days after the Severance Date. If your estimated payment exceeds the amount you are due, the excess will be a loan to you, which you must repay to the Company within five (5) business days after demand by the Company (together with interest at the rate provided in Code Section 1274(b)(2)(B)).

When payments are made to you, the Company will provide you with a written statement explaining how your payments were calculated and the basis for the calculations. This statement will include any opinions or other advice the Company has received from auditors or consultants as to the calculation of your benefits. If your benefit is affected by the golden parachute limitation in Section 8, the Company will provide you with calculations relating to that limitation and any supporting materials you reasonably need to permit you to evaluate those calculations.

8. Potential Limitations

a. Golden Parachute Limitation

Your aggregate payments and benefits under this Agreement and all other contracts, arrangements, or programs shall not exceed the maximum amount that may be paid without triggering golden parachute penalties under Section 280G and related provisions of the Internal Revenue Code, as determined in good faith by the Company's independent auditors. The preceding sentence shall not apply to the extent the shareholder approval requirements of Code Section 280G(b)(5) are satisfied. If your benefits must be reduced to avoid triggering such penalties, the Company shall reduce your benefits that are not considered deferred compensation subject to Code Section 409A before it reduces any benefits that are considered deferred compensation subject to Code Section 409A. If an amount in excess of the limit set forth in this Section is paid to you, you must repay the excess amount to the Company on demand, with interest at the rate provided in Code Section 1274(b)(2)(B). You and the Company agree to cooperate with each other reasonably in connection with any administrative or judicial proceedings concerning the existence or amount of golden parachute penalties on payments or benefits you receive.

b. Section 162(m) Limitation

To the extent payments or benefits under this Agreement would not be deductible under Code Section 162(m) if made or provided when otherwise due under this Agreement, they shall be made or provided later, immediately after Section 162(m) ceases to preclude their deduction, with interest thereon at the rate provided in Code Section 1274(b)(2)(B).

9. Disability

Following a Change in Control, while you are absent from work as a result of physical or mental illness, the Company will continue to pay you your full salary and provide you all other compensation and benefits payable to you under the Company's compensation or benefit plans, programs, or arrangements. These payments will stop if and when your employment is terminated by the Company for Disability as described in Section 20(h) hereof or at the end of the Term of this Agreement, whichever is earlier. Severance Benefits under this Agreement are not payable if you are terminated on account of your Disability.

10. Effect of Reemployment

Your Severance Benefits will not be reduced by any other compensation you earn or could have earned from another source.

11. Successors

a. Assumption Required

In addition to obligations imposed by law on a successor to the Company, during the Term of this Agreement the Company will require any successor to all or substantially all of the business or assets of the Company expressly to assume and to agree to perform this Agreement in the same manner and to the same extent that the Company was required to perform. If the Company fails to obtain such an assumption and agreement before the effective date of a succession, you will be entitled to Severance Benefits as if you were terminated by the Company without Cause on the effective date of that succession.

The appeal decision will be in writing, set forth in a manner calculated to be understood by you; it will include specific reasons for the decision, as well as specific references to the pertinent provisions of this Agreement on which the decision is based.

f. Procedures

The Company will adopt procedures by which initial claims and appeals will be considered and resolved; different procedures may be established for different claims. All procedures will be designed to afford you full and fair consideration of your claim.

g. Arbitration

Otherwise, the claim shall be void and deemed waived. The arbitrator may award any remedy that would otherwise be available to a court of competent jurisdiction.

The cost of such arbitration shall be paid by the Company, except you shall pay an administrative fee equivalent to the filing fee to initiate a similar claim in the local court of general jurisdiction if you are the party initiating the claim. The parties hereto agree that any action to compel arbitration pursuant to this Agreement may be brought in the appropriate Virginia state court, and in connection with such action to compel, the laws of Virginia shall control. Application may also be made to such court for confirmation of any decision or award of the arbitrator, for an order of enforcement and for any other remedies which may be necessary to effectuate such decision or award. The parties hereto hereby consent to the jurisdiction of the arbitrator and of such court and waive any objection to the jurisdiction of such arbitrator and court.
