WHEREAS, the Company and Consultant have mutually agreed to end Consultant’s employment relationship with the Company as of the Effective Date;

WHEREAS, notwithstanding the termination of Consultant’s employment with the Company, the Company believes that it will benefit from the maintenance of an ongoing consulting arrangement between Consultant and the Company, pursuant to which Consultant will provide certain services on an independent contractor basis as outlined below; and

WHEREAS, the Company and Consultant desire to establish and document the terms and conditions of the consulting relationship between them.

NOW, THEREFORE, in consideration of the premises, the mutual promises and obligations of the parties set forth herein and other good and valuable consideration, the receipt and legal sufficiency of which are hereby acknowledged, the parties agree as follows:

1.Appointment of Consultant; Services. Company appoints Consultant and Consultant hereby accepts appointment as an independent contractor to perform certain advisory services as may be requested by the Company from time to time (the “Services”).

2.    Term; Termination. This Agreement will be effective as of the Effective Date and will continue in effect until terminated by either party upon written notice to the other party.

3.    Duties of Consultant. During the term of this Agreement, Consultant agrees to make himself reasonably available to render at the request of the Company’s Chief Executive Officer, such Services as are reasonably requested by the Company. Consultant will devote a reasonable amount of time, not to exceed forty hours (40) per month, to the provision of the Services. The Company will use reasonable efforts to schedule the Services at times that are reasonably convenient to Executive. Notwithstanding anything herein to the contrary, the parties intend that the date of the termination of Consultant’s prior employment with the Company constitutes the date of Consultant’s “separation from service” from the Company within the meaning of Section 409A of the Internal Revenue Code of 1986, as amended, and the regulations promulgated thereunder, and the parties accordingly intend and agree that Consultant will not be expected or required to perform Services exceeding twenty percent (20%) of the average level of bona fide services he performed for the Company over the immediately preceding 36 months. For the purposes of determining whether a “separation from service” from the Company occurred within the meaning of Section 409A of the Internal Revenue

Code of 1986, as amended, and the regulations promulgated thereunder, the parties acknowledge and agree that Consultant worked more than 60 hours per week on average over the immediately preceding 36 months. Consultant agrees to diligently and competently perform the Services, provided that Consultant will at all times retain sole and absolute discretion and judgment in the manner and means of carrying out the Services.

4.    Services for Others. During his engagement with the Company, Consultant will be free to perform services for other persons and entities, provided that performance of such services does not materially interfere with Consultant’s performance of the Services under this Agreement, and provided further that Consultant will comply with Section 9 of this Agreement with respect to his services for or on behalf of other persons and entities.

5.    Compensation of Consultant.

(a)    As compensation for the performance of the Services, the Company will pay Consultant $375 per hour of Services provided and time incurred in furtherance of providing the Services (e.g., travel). Consultant agrees to invoice the Company on a monthly basis. Upon termination of this Agreement for any reason, Consultant will promptly provide the Company with an invoice as described above reflecting all unpaid fees through and including the date of termination, and the Company will pay such invoice within thirty (30) days from its receipt of the invoice.

Notwithstanding the foregoing, Consultant shall not be entitled to continue participation in a Health Plan if prohibited by the terms of such Health Plan.

(c)    In the event that Consultant is required to travel in order to perform the Services under this Agreement, the Company will reimburse Consultant for such reasonable travel expenses incurred by him upon the presentation by Consultant of a detailed and itemized account of such expenses with proper documentation and such other supporting information as the Company may reasonably request. Except as provided above with respect to travel expenses, the Company will not be responsible for payment or reimbursement of Consultant’s expenses in his performance of the Services, unless such expense is approved in advance by the Company.
