Upon Company’s request, Consultant agrees to devote its best efforts to provide to Company transition services and consultation pertaining to Consultant’s previous President and CFO duties and responsibilities (the “Services”), including a reasonable amount of informal consultation over the telephone or otherwise as requested by Company. The specific nature and amount of the Services to be performed shall be as determined by the Company during the term of this Agreement. Consultant shall only devote such time as is requested by the Company and shall render the Services at such times as may be mutually agreed between the parties. Consultant shall perform the Services at any Company location or at other places, upon mutual agreement of the parties hereto. Consultant will perform Services, and provide the results thereof, with the highest degree of professional skill and expertise. Consultant may use the assistance of other individuals only with the prior written consent of the Company.

Since Consultant’s service as an employee and a consultant will be continuous, Consultant’s termination of employment will not constitute a termination of service for purposes of the Company’s applicable stock or equity plan (the “Plan”). Thus, vesting of the Equity Awards will not cease as of the Separation Date and will continue for the duration of the Consulting Agreement. Consultant’s Equity Awards shall continue to be governed by the Plan and all applicable grant notices and agreements except as provided at Section 2 below.
