Employment at Will. The Company may terminate Executive's employment at any time for any reason, and Executive may terminate his employment with the Company at any time for any reason, and nothing in this Agreement shall be construed as giving either the Company or Executive any right or obligation to continue their employment relationship. 5. Discharge For Cause or Resignation without Good Reason.
