accordance with the regular payroll practices of Employer, and subject to
applicable deductions of withholding taxes and other customary employment taxes.

Employer shall reimburse Employee the lesser of the amount Employee pays for
said personal policy, as evidenced by adequate documentation, or what Employer

quotes from reputable movers and Employer shall pay the most competitive rate.

         Employer shall provide Employee a subsistence allowance of Two Thousand
Dollars ($2,000.00) per month for the lesser of nine months from the date of

         holidays: New Year's Day, Memorial Day, Independence Day, Labor Day,
         Thanksgiving Day and the day after Thanksgiving, and Christmas Day and
         all other holidays for Employees of the Company as approved by the
         Chief Executive Officer or Board of Directors.

                  B)       Employee is entitled to four weeks vacation during
         the first year of employment and for each year thereafter. Unused
         vacation in any given year shall accrue to following years up to a
         maximum of eight weeks in any one year.

         8.       RESPONSIBILITIES OF EMPLOYEE. The Employee shall devote such
reasonable time as is necessary or is deemed reasonably necessary by the
Employer to carry out all required duties and will devote full time to the
Employer during normal business hours. The Employee shall at all times
faithfully, with diligence and to the Employee's best good faith ability,
experience and talents, perform all the duties that may be required pursuant to
the express terms hereof to the reasonable satisfaction of the Employer, in
accordance with customary professional standards.

         9.       WORKING FACILITIES. The Employee shall be furnished with all
facilities and services suitable to Employee's position and adequate for the
performance of Employee's duties.

expenses for promoting business of the Employer, including expenses for
entertainment, travel and similar items. The Employer shall reimburse the
Employee for all such expenses on the presentation by the Employee of itemized
and adequately documented accounts of such expenditures.

         11.      DISABILITY. If unable to perform duties under the terms of

<PAGE>

commencing at the end of such four week period, be entitled to receive
Employee's compensation hereunder for a period of up to and including a maximum
of one year or until he is no longer disabled, whichever occurs first. After one
year of disability at full salary, the Employee, or his designated beneficiary,
shall be provided with a disability insurance policy, if available, at no cost
to Employee. The disability income policy would provide for monthly income
benefits at the rate of sixty percent (60%) of the Employee's base salary at the
time the disability occurred. The Company will attempt to procure a disability
income policy that would provide monthly benefits until the Employee reaches 65
years of age or is no longer disabled whichever occurs first. If such a policy
is unavailable, the Company will attempt to provide the best policy available.
If no policy is available, no other disability income benefits will be provided.

         12.      TERMINATION. This Employment Agreement may be terminated under
the following circumstances:

                  A)       WITHOUT CAUSE. Employer may terminate this Agreement
         at any time upon thirty (30) days written notice to Employee, but
         Employer shall be obligated to pay to Employee compensation in a lump

         termination, unless Employee agrees to other payment terms.

                  B)       VOLUNTARY TERMINATION BY EMPLOYEE WITHOUT CAUSE.
         Employee may terminate this Agreement at any time upon thirty (30) days
         written notice to Employer and Employer shall be obligated, in that
         event, to pay Employee compensation up to the date of the termination
         only. All accrued but unpaid compensation and Employee benefits shall
         be paid in cash within 30 days of termination, unless Employee agrees
