8.               Change of Control. Notwithstanding the foregoing, no shares shall vest on any vesting date specified above unless the undersigned is then, and since the date of grant has continuously been, employed by the Company or its subsidiaries.  In the event of a Change in Control, the Administrator may require that any amounts delivered, exchanged or otherwise paid in respect of outstanding and then unvested Shares be placed in escrow or otherwise made subject to such restrictions as the Administrator deems appropriate to carry out the intent of the Plan.  References in this Agreement to the Shares shall refer, mutatis mutandis, to any such restricted amounts. The term ‘Change in Control’ or ‘Change in Control of the Company’ shall mean the occurrence hereafter of any of the following:

(a)          Any Person, other than the Company or an Affiliate, becomes a beneficial owner (within the meaning of Rule 13d-3, as amended, as promulgated under the Securities Exchange Act of 1934, as amended), directly or indirectly, in one or a series of transactions, of securities representing more than fifty percent (50%) of the combined voting power of the Company’s then outstanding securities;

2

(b)         The consummation of a merger or consolidation of the Company with any other Person, other than a merger or consolidation which would result in the voting securities of the Company outstanding immediately prior thereto continuing to represent (either by remaining outstanding or by being converted into voting securities of the surviving entity) more than fifty percent (50%) of the combined voting power of the voting securities of the Company or such surviving entity outstanding immediately after such merger or consolidation;

(c)          The closing of a sale or other disposition by the Company of all or substantially all of the assets of the Company;

(d)         Individuals who constitute the Board of Directors on the date hereof (“Incumbent Directors”) cease for any reason to constitute at least a majority of the board; provided, that any individual who becomes a member of the Board subsequent to the date hereof, whose election or nomination for election was approved by a vote of at least two-thirds of the Incumbent Directors shall be treated as an Incumbent Director unless he or she assumed office as a result of an actual or threatened election contest with respect to the election or removal of directors; or

(e)          A complete liquidation or dissolution of the Company;

provided, in each case, that such event also constitutes a “change in control event” within the meaning of Treasury Regulation Section 1.409A-3(i)(5).

10.         Vesting Upon Death.  If the Participant’s employment is terminated by reason of his or her death, the Shares shall become vested, and the restrictions lifted, on a prorated basis reflecting the percentage of such Shares that was accrued by the Company on its books at the time of the Participant’s death.  In such event, the restrictions will be lifted from such prorated portion of the Shares, and such prorated Shares shall be freely transferable to the person(s) to whom the Participant’s share rights pass by will or by the applicable laws of descent and distribution.

11.         Legend.  Any certificates representing unvested Shares shall be held by the Company, and any such certificate shall contain a legend substantially in the following form:

THE TRANSFERABILITY OF THIS CERTIFICATE AND THE SHARES OF STOCK REPRESENTED HEREBY ARE SUBJECT TO THE TERMS AND CONDITIONS (INCLUDING FORFEITURE) OF AMERICAN SCIENCE & ENGINEERING, INC, 2005 EQUITY AND INCENTIVE PLAN AND A RESTRICTED STOCK AWARD AGREEMENT ENTERED INTO BETWEEN THE REGISTERED OWNER AND AMERICAN SCIENCE & ENGINEERING, INC.  COPIES OF SUCH PLAN AND AGREEMENT ARE ON FILE IN THE OFFICES OF AMERICAN SCIENCE & ENGINEERING, INC.

As soon as practicable following the vesting of any such Shares the Company shall cause a certificate or certificates covering such Shares, without the aforesaid legend, to be issued and delivered to the undersigned.  If any Shares are held in book-entry form, the Company may take such steps as it deems necessary or appropriate to record and manifest the restrictions applicable to such Shares.

12.         Dividends, etc.  The undersigned shall be entitled to (i) receive any and all dividends or other distributions paid with respect to those Shares of which he is the record owner on the record date for such dividend or other distribution, and (ii) vote any Shares of which he is the record owner on the record date for such vote; provided, however, that any property (other than cash) distributed with respect to a share of Stock (the “associated share”) acquired hereunder, including without limitation a distribution of Stock by reason of a stock dividend, stock split or otherwise, or a distribution of other securities with respect to an associated share, shall be subject to the restrictions of this Agreement in the same manner and for so long as the associated share remains subject to such restrictions, and shall be promptly forfeited if and when the associated share is so forfeited;  and further provided, that the Administrator may require that any cash distribution with respect to the Shares other than a normal cash dividend be placed in escrow or otherwise made subject to such restrictions as the Administrator deems appropriate to carry out the intent of the Plan.  References in this Agreement to the Shares shall refer, mutatis mutandis, to any such restricted amounts.

13.         Sale of Vested Shares.  The undersigned understands that he will be free to sell any Share once it has vested, subject to (i) satisfaction of any applicable tax withholding requirements with respect to the vesting or transfer of such Share; (ii) the completion of any administrative steps (for example, but without limitation, the transfer of certificates) that the Company may reasonably impose; and (iii) applicable requirements of federal and state securities laws.

14.         Certain Tax Matters.  The undersigned expressly acknowledges the following:

(a)          The undersigned has been advised to confer promptly with a professional tax advisor to consider whether the undersigned should make a so-called “83(b) election” with respect to the Shares.  Any such election, to be effective, must be made in accordance with applicable regulations and within thirty (30) days following the date of this Award.  The Company has made no recommendation to the undersigned with respect to the advisability of making such an election.

4

(b)         The award or vesting of the Shares acquired hereunder, and the payment of dividends with respect to such Shares, may give rise to “wages” subject to withholding.  The undersigned expressly acknowledges and agrees that his rights hereunder are subject to his promptly paying to the Company in cash (or by such other means as may be acceptable to the Company in its discretion, including, if the Administrator so determines, by the delivery of previously acquired Stock or shares of Stock acquired hereunder or by the withholding of amounts from any payment hereunder) all taxes required to be withheld in connection with such award, vesting or payment.
