(“Holdings”) and/or one or more of the Company’s Subsidiaries.

2.             Status as an Independent Contractor.  Contractor is and shall remain an independent contractor of the Company and is not and shall not be deemed to be an employee, partner or joint venturer with the Company.

Contractor acknowledges that the Company shall not be responsible for deducting withholding taxes, payroll taxes, social security taxes or other similar items from compensation paid to Contractor. Contractor shall be solely responsible for any and all such taxes, payments, deductions, or contributions.  As an independent contractor, Contractor shall not be entitled to participate in or receive benefits under any insurance, benefit or bonus plans offered by the Company to its employees. Contractor agrees to indemnify the Company and hold the Company harmless from any and all claims or penalties asserted against the Company for any failure by Contractor to pay taxes due on any form of compensation provided by the Company pursuant to this Agreement.

3.             Term.      The term of this Agreement shall be three (3) years from the Effective Date (“Term”) unless otherwise terminated according to the provisions set forth in Section 5 hereof.

4.             Performance and Compensation.

(b)           Compensation and Billing.  The Company shall pay Contractor at the rate of $400 per hour worked up to a maximum of $3,200 per day and a maximum of $16,000 per week.  Contractor shall record time spent performing Services and shall provide documentation to the Company in such form and time intervals as may be requested by the Company to evidence hours worked.

(c)           Stock Options.  On the Effective Date or the date Contractor commences Services for the Company, whichever is later, the Company shall grant Contractor non-statutory stock options to purchase 600,000 shares of Class B common stock of the Company (“Options”).  The Options will have a ten-year term and an exercise price equal to $2.00 per share.  One-third (1/3) of the total Option shares will vest on each anniversary of the Effective Date subject also to the pro rata vesting set forth in this Section 3(c).  The Options will be subject to the terms and conditions of the 2006 Equity Investment Plan and applicable Form of Stock Option Agreement, as they may be amended from time to time by the Compensation Committee of the Board in its sole discretion.  Upon a Change of Control, the Options will automatically vest provided Contractor is performing Services at the time of the Change of Control.  Options and option shares shall be nonvoting ownership and shall have only those rights as determined by the Compensation Committee of the Board in its sole discretion.  If Contractor’s Services are terminated for Cause, all vested and unvested Options and option shares will be forfeited without further action.

If Contractor’s Services are terminated for any other reason other than for Cause then (i) Contractor shall retain Options and option shares that were vested as of the date immediately preceding the Termination Date; and (ii) Contractor shall become vested in additional Options automatically on the Termination Date which shall be calculated by the following formula (which shall be rounded to the nearest whole number of Options): (F/365) X 200,000, where F is the number of calendar days between the immediately preceding anniversary of the Effective Date (or the Effective Date if no such anniversary thereof shall have occurred) and the Termination Date; and (iii) remaining unvested Options and option shares will be forfeited.  Options not exercised by Contractor within ninety (90) days after the Termination Date will be forfeited.

(d)           Business Expenses.  The Company shall pay or reimburse Contractor for all reasonable and necessary business expenses incurred or paid by Contractor in the performance of the Services, subject to any maximum annual limit or other restrictions on such expenses set by the Company and to such reasonable substantiation and documentation as may be specified by the Company from time to time; provided, however, that notwithstanding the policies of the Company regarding travel expenses, Contractor shall be permitted reasonable reimbursement for fuel consumed in the use of Contractor’s private airplane when used for travel in connection with the Services, subject to a maximum reimbursement of $3,500 per trip.

9.             Assignment of Rights to Intellectual Property.  Contractor shall promptly and fully disclose all Intellectual Property to the Company, and Contractor hereby acknowledges that all such Intellectual Property is the property of the Company.  Contractor hereby assigns and agrees to assign to the Company (or as otherwise directed by the Company) Contractor’s full right, title and interest in and to all Intellectual Property.  Contractor agrees to execute any and all applications for domestic and foreign patents, copyrights or other proprietary rights and to do such other acts (including without limitation the execution and delivery of instruments of further assurance or confirmation) requested by the Company to assign the Intellectual Property to the Company and to permit the Company to enforce any patents, copyrights or other proprietary rights to the Intellectual Property.  Contractor will not charge the Company for time spent in complying with these obligations.  All copyrightable works that Contractor creates shall be considered “work made for hire”.  Notwithstanding the foregoing, this Section 9 shall not apply to any Intellectual Property which no equipment, supplies, facility or trade secret information of the Company, Holdings or any of the Company’s Subsidiaries was used and which was developed entirely on Contractor’s own time, and (i) which does not relate (A) directly to the business of the Company, Holdings or any of the Company’s Subsidiaries or (B) such entities’ actual or demonstrably anticipated research development, or (ii) which does not result from any work performed by the Contractor for the Company, Holdings or any the Company’s Subsidiaries.

11.           Conflicting Agreements. Contractor hereby represents and warrants that the execution of this Agreement and the performance of Contractor’s obligations hereunder will not breach or be in conflict with any other agreement to which Contractor is a party or is bound and that Contractor is not now subject to any covenants against competition or similar covenants or any court order or other legal obligation that would affect the performance of his obligations hereunder.  Contractor will not disclose to or use on behalf of the Company any proprietary information of a third party without such party’s consent.
