3.01 Amendment and Termination. This Agreement may not be amended, suspended, discontinued or terminated at any time without the written consent of all of the parties hereto.

3.02 Limitation of Executive’s Right. Nothing in this Agreement shall be construed as conferring upon the Executive any right to continue in the employment of Company, nor shall it interfere with the rights of Company to terminate the employment of the Executive and/or to take any personnel action affecting the Executive without regard to the effect which such action may have upon the Executive as a recipient or prospective recipient of benefits under this Agreement. Any amounts payable hereunder shall not be deemed salary or other compensation to the Executive for the purposes of computing benefits to which the Executive may be entitled under any other arrangement established by Company for the benefit of its employees.

3.03 No Limitation on Company Actions. Nothing contained in the Agreement shall be construed to prevent Company from taking any action that is deemed by it to be appropriate or in its best interest.

3.04 Obligations to Company. If the Executive becomes entitled to a distribution of benefits under this Agreement, and if at such time the Executive has outstanding any debt, obligation, or other liability representing an amount owing to Company, then Company may offset such amount owed to it against the amount of benefits otherwise distributable.

The Executive, however, shall be responsible for the payment of all individual tax liabilities relating to any such benefits.

3.08 Severability. If any provision of this Agreement is held unenforceable, the remainder of the Agreement shall continue in full force and effect without regard to such unenforceable provision and shall be applied as though the unenforceable provision were not contained in the Agreement.
