Cause, Disability or death), then the Company shall pay to you in a single lump sum (net of standard tax withholdings) on the last day of your full time employment with the Company an amount equal to (i) six (6) months of your then base salary, and
(ii) fifty percent (50%) of your total annual bonus potential; plus the benefit described in Section 3 below. 
  
 2. If following a Change in Control of the Company your employment with the Company is terminated by you for Good Reason, then the Company shall pay to
