WHEREAS, Consultant and the Company have previously entered into that certain Consulting Agreement (the “Original Consulting Agreement”) effective as of April 25, 2003 (the “Effective Date”); and

WHEREAS, Consultant and the Company now desire to amend and restate the terms of the Original Consulting Agreement and to supersede it in its entirety with the terms set forth herein.

NOW THEREFORE, in consideration of the mutual promises contained herein, Company and Consultant agree as follows:

1.    Consulting Relationship.    During the term of this Agreement, Consultant will provide consulting services (the “Services”) to the Company as described on Exhibit A attached to this Agreement.

As a condition to receipt of reimbursement, Consultant shall be required to submit to the Company reasonable evidence that the amount involved was expended and related to Services provided under this Agreement.

4.    Term and Termination.    Consultant shall serve as a consultant to the Company for a period commencing on the Effective Date and terminating on June 30, 2004; provided, however, that the Consulting Relationship shall terminate prior to such date if at any time after July 24, 2003, the Company desires to terminate this Agreement. Such termination shall be effective upon ten days’ prior written notice to Consultant, which notice shall be executed by the Chairman of the Company’s Board of Directors. In the event that this Agreement is terminated by the Company, Consultant shall receive a termination fee (the “Termination Fee”) equal to the greater of (i) the amount owed to Consultant for the remaining term of this Agreement or (ii) the amount owed to Consultant for the provision of an additional three months of Services, each in accordance with the schedule set forth on Exhibit B attached to this Agreement. The Termination Fee shall be paid to Consultant in a lump sum payment. In the event that this Agreement is terminated by Consultant, Consultant shall be paid for any portion of the Services that have been performed prior to the date of such termination.

5.    Independent Contractor.    Consultant’s relationship with the Company will be that of an independent contractor and not that of an employee.

(a)    Method of Provision of Services:    Consultant shall be solely responsible for determining the method, details and means of performing the Services. Consultant may, at Consultant’s own expense, employ or engage the service of such employees or subcontractors as Consultant deems necessary to perform the Services required by this Agreement (the “Assistants”). Such Assistants are not the employees of the Company and Consultant shall be wholly responsible for the professional performance of the Services by his Assistants such that the results are satisfactory to the Company. Consultant shall expressly advise the Assistants of the terms of this Agreement, and shall require each Assistant to execute a Confidential Information and Invention Assignment Agreement substantially in the form attached to this Agreement as Exhibit C (the “Confidentiality Agreement”).

(c)    No Benefits.    Consultant acknowledges and agrees that Consultant (or Consultant’s employees, if Consultant is an entity) will not be eligible for any Company employee benefits and, to the extent Consultant (or Consultant’s employees, if Consultant is an entity) otherwise would be eligible for any Company employee benefits but for the express terms of this Agreement, Consultant (on behalf of itself and its employees) hereby expressly declines to participate in such Company employee benefits.

(d)    Withholding; Indemnification.    Consultant shall have full responsibility for applicable withholding taxes for all compensation paid to Consultant, its partners, agents or its employees under this Agreement, and for compliance with all applicable labor and employment requirements with respect to Consultant’s self-employment, sole proprietorship or other form of business organization, and Consultant’s partners, agents and employees, including state worker’s compensation insurance coverage requirements and any US immigration visa requirements. Consultant agrees to indemnify, defend and hold the Company harmless from any liability for, or assessment of, any claims or penalties with respect to such withholding taxes, labor or employment requirements, including any liability for, or assessment of, withholding taxes imposed on the Company by the relevant taxing authorities with respect to any compensation paid to Consultant or Consultant’s partners, agents or its employees.

6.    Supervision of Consultant’s Services.    All of the Services to be performed by Consultant, including but not limited to the Services, will be as agreed between Consultant and the Chairman of the Company’s Board of Directors. Consultant will be required to report to the Chairman of the Company’s Board of Directors concerning the Services performed under this Agreement. The nature and frequency of these reports will be left to the discretion of the Chairman of the Company’s Board of Directors.

If, however, Consultant decides to do so, Consultant agrees that, in advance of accepting such work, Consultant will promptly notify the Company in writing, specifying the organization with which Consultant proposes to consult, provide services, or become employed by and to provide information sufficient to allow the Company to determine if such work would conflict with the terms of this Agreement, including the terms of the Confidentiality Agreement, the interests of the Company or further services which the Company might request of Consultant. If the Company determines that such work conflicts with the terms of this Agreement, the Company reserves the right to terminate this Agreement immediately.

8.    Confidentiality Agreement.    Consultant shall sign, or has signed, a Confidential Information and Invention Assignment Agreement substantially in the form attached to this Agreement as Exhibit C (the “Confidentiality Agreement”), on or before April 25, 2003. In the event that Consultant is an entity or otherwise will be causing individuals in its employ or under its supervision to participate in the rendering of the Services, Consultant warrants that it shall cause each of such individuals to execute a Confidentiality Agreement in the form attached as Exhibit C.

9.    Conflicts with this Agreement.    Consultant represents and warrants that neither Consultant nor any of Consultant’s partners, employees or agents is under any pre-existing obligation in conflict or in any way inconsistent with the provisions of this Agreement. Consultant represents and warrants that Consultant’s performance of all the terms of this Agreement will not breach any agreement to keep in confidence proprietary information acquired by Consultant in confidence or in trust prior to commencement of this Agreement. Consultant warrants that Consultant has the right to disclose and/or or use all ideas, processes, techniques and other information, if any, which Consultant has gained from third parties, and which Consultant discloses to the Company or uses in the course of performance of this Agreement, without liability to such third parties. Notwithstanding the foregoing, Consultant agrees that Consultant shall not bundle with or incorporate into any deliveries provided to the Company herewith any third party products, ideas, processes, or other techniques, without the express, written prior approval of the Company. Consultant represents and warrants that Consultant has not granted and will not grant any rights or licenses to any intellectual property or technology that would conflict with Consultant’s obligations under this Agreement. Consultant will not knowingly infringe upon any copyright, patent, trade secret or other property right of any former client, employer or third party in the performance of the Services required by this Agreement.
