NOW, THEREFORE, the Company and the Executive hereby agree as follows:

1. Definitions. For purposes of this Agreement only, the following definitions shall apply:

(i) deliberate dishonesty by the Executive in connection with his employment;

(ii) willful and prolonged absence from work (other than as a result of illness or incapacity) in circumstances that constitute a substantial abdication of the Executive’s responsibilities to the Company after written notice thereof has been given by the Board of Directors of the Company to the Executive;

(iii) material violation of any code of conduct or standard of ethics of the Company applicable to the Executive; or

(iv) the Executive’s conviction of, or pleading of guilty or nolo contendere to, a felony.

For purposes of this definition, no act or failure to act on the Executive’s part shall be deemed “willful” unless done or omitted to be done by the Executive not in good faith and without reasonable belief that his action or omission was in the best interests of the Company.

(b) “Change in Control” means the occurrence of any of the following events:

(i) any “person” (as such term is used in Sections 13(d) and 14(d) of the Exchange Act), other than the Company, any trustee or other fiduciary holding securities under an employee benefit plan of the Company or a corporation owned, directly or indirectly, by the stockholders of the Company in substantially the same proportions as their ownership of stock of the Company becomes the “beneficial owner” (as defined in Rule 13d-3 under the Exchange Act), directly or indirectly, of securities of the Company representing 45% or more of the combined voting power of the Company’s then outstanding securities;

(ii) during any period of twenty-four (24) consecutive months (not including any period prior to the date of this Agreement), individuals who at the beginning of such period constitute the Board and any new director (other than a director designated by a person who has entered into an agreement with the Company to effect a transaction described in subparagraphs (i), (ii) or (iii)) whose election by the Board or nomination for election by the Board or by the stockholders of the Company was approved by a vote of at least a majority of the directors then still in office who either were directors at the beginning of such period or whose election or nomination for election was previously so approved, cease for any reason to constitute a majority thereof; or

(iii) the stockholders of the Company approve a merger or consolidation of the Company with any other corporation, other than (i) 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) at least 50% of the combined voting securities of the Company or such surviving entity outstanding immediately after such merger or consolidation or (ii) a merger or consolidation effected to implement a recapitalization of the Company (or similar transaction) in which no “person” (as hereinabove defined) acquires 45% or more of the combined voting power of the Company’s then outstanding securities; or

(iv) the stockholders of the Company approve a plan of complete liquidation of the Company or an agreement for the sale or disposition by the Company of all or substantially all of the Company’s assets.

(c) “Disability” means such physical or mental incapacity as to make the Executive unable to perform the essential functions of his employment duties for a period of at least six months with or without reasonable accommodation. If any question shall arise as to whether during any period the Executive is so disabled as to be unable to perform the essential functions of his employment duties with or without reasonable accommodation, the Executive may, and at the request of the Company shall, submit to the Company a certification in reasonable detail by a physician selected by the Company to whom the Executive or the Executive’s guardian has no reasonable objection as to whether the Executive is so disabled or how long such disability is expected to continue, and such certification shall for the purposes of this Agreement be conclusive of the issue. The Executive shall cooperate with any reasonable request of the physician in connection with such certification. If such question shall arise and the Executive

shall fail to submit such certification, the Company’s determination of such issue shall be binding on the Executive.

(iv) the Executive is prevented by the Company from continuing to fulfill his responsibilities at a level commensurate with that prior to the Change in Control; or

(iv) the Company shall have failed to obtain, at the Executive’s request, an assent to the Company’s performance of its obligations under this Agreement from any person that succeeds or has the practical ability to control (either immediately or with the passage of time), directly or indirectly, the Company’s business.
