SECTION 2. Consulting Services. Consultant hereby agrees to provide such consulting services to the Company during the Term with respect to such matters pertaining to the Company’s business and affairs as may be requested of Consultant from time to time by the Company’s Board of Directors (the “Board”) or President, provided that Consultant shall not be obligated to consult on any matter that would not be appropriate for an executive-level consultant or a member of senior management. In this regard, Consultant shall be generally available to provide consulting services to the Board during normal business hours, upon reasonable notice, throughout the Term, it being the intent of the parties that Consultant may provide such services

In performing Consultant’s services hereunder, Consultant shall be an independent contractor and shall not be, or be deemed to be, an employee or agent of the Company. Except as may be specifically authorized in a writing in advance by the President or the Board of Directors of the Company, Consultant shall have no right or authority to act for or on behalf of the Company or otherwise to enter into any agreements or make any commitments with third parties binding upon the Company.

(c) the Consultant’s termination of the Term, upon written notice to the Company, if the Company breaches the terms of this Agreement and, within ten (10) days following written notice by the Consultant to the Company of such breach, the Company has failed to cure such breach.
