Compensation and Employee Benefits. You will be paid a starting salary at the rate of $250,000 annually, subject to an annual compensation review each year beginning February 1, 2002, and payable in accordance with the Company's standard payroll schedule.

In addition, executive benefits for medical insurance and other executive perquisites will be provided for six months. If there is a change of control of the Company as defined in paragraph 3 herein, within one year following a change of control of the Company, you may terminate your employment with the Company if, during that one year period without your written consent, there has occurred a significant diminution of, or assignment to you of any duties inconsistent with your title, status, duties or responsibilities as in effect as of the beginning of your employment with Mercator. This right of termination can be exercised only if you give written notice to the Company within thirty (30) days of the occurrence of the significant diminution of, or assignment to you of any duties inconsistent with your title, status, duties or responsibilities as in effect as of the beginning of your employment with Mercator which you rely upon to terminate this agreement. If you elect to terminate your employment pursuant to this provision, upon such termination Mercator shall pay you twelve (12) months of base salary in accordance with the Company's usual payroll practices. 8. Employment Relationship. The term of your employment with the Company is for no specific period of time.
