(i) Three (3) months following entry into this Agreement, the Executive shall be entitled to severance pay equal to six months of Executive’s Base Salary, with the severance increasing by an amount equal to one month of Executive’s Base Salary pay

for each complete year of employment starting on the first Anniversary of the Effective Date and continuing until the severance is equal to one year of Executive’s Base Salary at which time the severance pay shall be capped at one year of Executive’s Base Salary.
