Consultant shall report directly to the Successor CEO. Consultant and Company acknowledge and agree that a significant portion of the Advisory Services are expected to be provided remotely by Consultant and that Consultant will not be provided a designated office or administrative support (and any work space and/or administrative support for Consultant will be provided only on an “as-needed” basis as determined by the Successor CEO). Company acknowledges and agrees that Consultant is not obligated to incur any out-of-pocket or administrative expenses in connection with the performance of Advisory Services unless reimbursed in accordance with this Agreement.

Such COBRA Reimbursement shall be subject to withholding for applicable taxes or deductions and reporting on IRS Form W-2.

7.     Enforcement of Terms. Failure to insist upon strict compliance with any of the terms, covenants, or conditions thereof shall not be deemed a waiver of any such term, covenant or condition, nor shall such failure at any one time or more times be deemed a waiver or relinquishment of any other time or times of any right under the terms, covenants, or conditions thereof. If any provision thereof shall be determined to be unlawful or improper, or unenforceable for any other reason, the remaining provisions of this Agreement shall remain in full force and effect.

8.     Modifications. No modification hereof shall be effective unless the same be in writing duly executed by all parties hereto.

This Agreement shall not be subject to any claim of mistake of fact and is intended to be final and complete. Section headings are for reference purposes only and do not affect the interpretation of this Agreement.

11.     Severability. To the extent any provision of this Agreement shall be invalid or unenforceable, it shall be considered deleted and the remainder of such provisions and of this Agreement shall be unaffected and shall continue in full force and effect. In furtherance and not in limitation of the foregoing, should the duration or geographical extent of, or business activities covered by any provision of this Agreement be in excess of that which is valid and enforceable under applicable law, then such provision shall be construed to cover only that duration, extent or activities which may validly and enforceably be covered. Consultant acknowledges the uncertainty of the law in this respect and expressly stipulates that this Agreement shall be given the construction that renders the provisions valid and enforceable to the maximum extent (not exceeding its express terms) possible under applicable law.

IN WITNESS WHEREOF, Consultant hereby executes this Agreement on the date indicated below.
