Employee shall also, during and after Employee’s employment, execute such written instruments and render such other assistance as the Employer shall reasonably request to obtain and maintain patents, design patents, or other forms of protection on any Employer Inventions and to vest and confirm in the Employer its entire right, title and interest therein. In this regard, Employee shall be reimbursed by the Employer for actual expenses incurred and, if no longer an employee of the Employer, shall be reasonably compensated for assistance rendered.

7.2 Proprietary Information.

(a) Employee understands that as a consequence of Employee’s employment by the Employer, proprietary data and confidential information (both hereinafter referred to as “Information”) relating to the business of the Employer may be disclosed to Employee or developed by Employee which is not generally known in the Employer’s trade and which is of considerable value to the Employer. Such Information includes, without limitation, information about trade secrets, the Employer Inventions (as previously defined), patents, licenses, research projects, costs, profits, markets, sales, customer lists, plans for future development, and any other information of a similar nature to the extent not generally known in the trade.

7.3 Remedies. Employee recognizes that irreparable injury may result to the Employer, its business and property, in the event of a breach of any of the agreements, assurances and understandings contained herein. Employee further recognizes that in the event of such a breach, or the substantial likelihood that such a breach will occur, the Employer intends to take legal action, and to seek injunctive relief if available, in accordance with the language and spirit of this Agreement in order to protect fully its interests and property. For the period beginning with the consummation of a Change in Control, the Employer agrees to pay as incurred, to the full extent permitted by law, all legal fees and expenses which the Employee may reasonably incur as a result of any contest, dispute or litigation by the Employee or others of the validity or enforcement of, or liability under, any provision of this Agreement unless the Employee is not the prevailing party in such contest, dispute or litigation in which event the Employee shall also repay any legal fees or expenses previously advanced by the Employer in the same connection.

8. Covenant Not to Compete.

(a) The Employee recognizes that the Employer is engaged in the development and sale of III-V compounds used in semiconductors and related products in Massachusetts and throughout the United States and the world and in the development of liquid crystal electronic imaging devices and display products based thereon (collectively, the “Principal Business”). In the event of the termination of the Employee’s employment hereunder, voluntarily or involuntarily, and so long as the Employer is not in material breach of its obligations to the Employee hereunder, the Employee agrees that, for a period of twelve (12) months from the date of such termination, he will neither (i) engage in the Principal Business directly for himself, or in conjunction with or on behalf of any commercial entity, or (ii) work as an employee in the Principal Business for any commercial entity, where either (A) the Employee’s duties in the course of any such activities would be substantially similar to those he has performed for the Employer hereunder or (B) the Employee’s duties in the course of such activities would involve disclosure or use of any confidential or proprietary information relating to the business of the Employer which he may in any way acquire by reason of his employment by the Employer. The Employee’s obligation under this Section 8 shall extend to all geographical areas of the United States and the world in which the Employer, as set forth above, carries on business, either directly or indirectly, including, but not limited to, places where the Employer has a place of business, has employees or representatives, or has advertised or sold any products during the time period specified in this section.

(b) The Employee further agrees that for a period of twelve (12) months from the date of termination of his employment, he will not on behalf of himself or any commercial competitor of the Employer, compete for, or engage in the solicitation of, with respect to the Employer’s products or services, any commercial customer of the Employer, that he has, during the one year immediately preceding such termination, solicited or serviced on behalf of the Employer or that has been so solicited or serviced, during such period, by any person under the Employee’s supervision.

3

(c) The Employee further agrees that for a period of twelve (12) months after the date of termination of his employment, he will not, on behalf of himself or any other commercial competitor of the Employer, solicit or attempt to solicit for employment, recruit or hire any employee or independent contractors of the Employer (or any person who was an employee or independent contractor of the Employer during the six (6) month period prior to such activity by the Employee), or induce, attempt to induce or encourage any such person to terminate his or her association with the Employer.

(d) In the event of any violation of the foregoing provisions of this Section 8, the Employer shall be entitled, in addition to any other rights or remedies it may have, to injunctive relief, it being agreed that the damages which the Employer would sustain upon any such violation are difficult or impossible to ascertain in advance and that the Employee’s violations may cause irreparable harm to the Employer.

9. Post-Termination and Related Matters.

9.1 Termination by Employer without Cause; Resignation for Good Reason. If prior to the expiration of the Employment Term the Employee is terminated by the Employer without Cause (as defined in Section 9.2(b) below) other than by reason of death or disability, or the Employee resigns for Good Reason (as defined in Section 9.2(c) below) within twelve (12) months following a Change in Control (as defined in Section 9.2(d) below) of the Employer, Employer shall pay the following amounts and provide the following benefits to the Employee:

(a) an amount equal to the sum of the Employee’s earned but unpaid base salary and pro-rated annual bonus through the date of Employee’s termination, which prorated annual bonus shall be calculated by reference to his then current year’s target annual bonus, the base salary portion of such amount shall be paid on the Employer’s next regularly scheduled pay date for executives following the Termination Date, and the bonus portion of such amount shall be paid within thirty (30) days following the Termination Date;

(b) severance pay in the amount of $1.2 million, which amount will be paid to Employee in twenty-four (24) equal monthly installments during the two-year period following the Termination Date commencing with the next regularly scheduled pay date for executives following the Termination Date;

(c) an amount equal to the value of Employee’s accrued but unpaid vacation days, which amount shall be paid on the Employer’s next regularly scheduled pay date for executives following the Termination Date;

(d) $25,000 per year (commencing with the next regularly scheduled pay date for executives following the Termination Date) for ten (10) years following the Employee’s Termination Date to enable the Employee to purchase for himself and his spouse supplemental health insurance coverage (including Medicare Part B, Medicare Part D, and Medigap coverage) beyond the coverage that they may obtain from Medicare Part A; and

(e) immediately vest all options to purchase Employer Stock, all stock appreciation rights, all restricted stock awards, and any other compensatory equity awards, granted by the Employer to the Employee.

4

Any amounts payable under this Section 9.1 shall be subject to applicable tax withholding. It is the intention of the parties that this Agreement comply with and be interpreted in accordance with Section 409A of the Internal Revenue Code of 1986, as amended and the United States Department of Treasury regulations and other guidance issued thereunder (collectively, “Section 409A”). Each payment in a series of payments provided to the Employee pursuant to this Agreement will be deemed a separate payment for purposes of Section 409A. If any amount payable under this Agreement upon a termination of employment is determined by the Employer to constitute nonqualified deferred compensation for purposes of Section 409A (after taking into account the short-term deferral exception and the involuntary separation pay exception of the regulations promulgated under Section 409A which are hereby incorporated by reference), such amount shall not be paid unless and until the Employee’s termination of employment also constitutes a “separation from service” from the Employer for purposes of Section 409A. In the event that the Employee is determined by the Employer to be a “specified employee” for purposes of Section 409A at the time of his separation from service with the Employer, then any payments of nonqualified deferred compensation (after giving effect to any exemptions available under Section 409A) otherwise payable to the Employee during the first six (6) months following his separation from service shall be delayed and paid in a lump sum upon the earlier of (x) the Employee’s date of death, or (y) the first day of the seventh month following the Employee’s separation from service, together with interest on such delayed payments at the prime rate as published in the Eastern edition of The Wall Street Journal on the business day immediately preceding the Employee’s separation from service and the balance of the installments (if any) will be payable in accordance with their original schedule. To the extent any expense, reimbursement or in-kind benefit provided to the Employee constitutes nonqualified deferred compensation for purposes of Section 409A, (i) the amount of any expense eligible for reimbursement or the provision of any in-kind benefit with respect to any calendar year shall not affect the amount of expense eligible for reimbursement or the amount of in-kind benefit provided to the Employee in any other calendar year, (ii) the reimbursements for expenses for which the Employee is entitled to be reimbursed shall be made on or before the last day of the calendar year following the calendar year in which the applicable expense is incurred, and (iii) the right to payment or reimbursement or in-kind benefits hereunder may not be subject to liquidation for any other benefit.

9.2 Other.

(a) “Termination Date” shall mean the earlier of (i) the expiration of the Employment Term, or (ii) the date the Employee’s employment is terminated (x) by his death, then the date of his death, (y) by his long-term disability, then the date of his occurrence of his long-term disability, or (z) for any other reason (including the Employee’s resignation for Good Reason following a Change in Control), then the date on which such termination of employment is to be effective pursuant to the notice of termination to be given by the party terminating the relationship.

Any Cause that results in adverse publicity concerning the Employer or damage to the Employer’s business or reputation shall be deemed to be incurable.

(c) “Good Reason” shall mean the occurrence, without the Employee’s written consent, of any of the following events or circumstances:

(i) the assignment to the Employee of duties that are inconsistent in any material respect with the Employee’s position (including status, offices, titles, and reporting requirements), authority, or responsibilities, or any other action or omission by the Employer that results in a material diminution in such position, authority, or responsibility;

(ii) a reduction in the Employee’s base salary, other than as part of a similar reduction in base salary for all senior executive employees of the Employer but not to exceed 15% of the Employee’s base salary;

(iii) the failure by the Employer to (1) continue in effect any material compensation or benefit plan or program in which the Employee participates, or that is applicable to the Employee, unless an equitable arrangement providing substantially similar benefits in the aggregate (embodied in an ongoing substitute or alternative plan) has been made with respect to such plan or program, (2) continue the Employee’s participation therein (or in such substitute or alternative plan) on a basis not materially less favorable, in terms of the monetary value of benefits provided , or (3) award annual bonuses to the Employee in amounts and in a manner substantially consistent with the Employer’s past practice in light of the Employer’s financial performance;

(vii) any material breach by the Employer of this Agreement.

A termination by the Employee for Good Reason may not occur until thirty (30) days after the Employee has given the Board of Directors written notice specifying the ground(s) for such termination for Good Reason and an opportunity during such thirty (30) day notice period for the Board of Directors of the Employer to discuss such notice with the Employee, and then only if the Employer has failed to cure the event or circumstance (including compensation for any losses or damages resulting therefrom) giving rise to such Good Reason, if such Good Reason is curable.

The failure of any successor (whether direct or indirect, by purchase, merger, consolidation, or otherwise) to all or substantially all of the business or assets of the Employer to assume this Agreement or to perform the Employer’s obligations under this Agreement shall, at the election of the Employee, be deemed to constitute a termination of the Employee by the Employer without Cause.
