         In consideration of the promises herein contained, the parties hereto
mutually agree as follows:

         1. Employment: The Corporation hereby employs the Executive as its
Chief Financial Officer with such powers and duties as may be specified by the
Board of Directors. The Executive hereby accepts employment upon the terms and

         4. Authorized Expenses: The Executive is authorized to incur reasonable
expenses for the promotion of the business of the Corporation. The Corporation
will reimburse the Executive for all such reasonable expenses upon the
presentation by the Executive, from time to time, of an itemized account of such
expenditures.

         The Executive shall be entitled to such additional and other fringe
benefits as the Board of Directors shall from time to time authorize, including
but not limited to: A) health insurance coverage for the Executive, his wife and
minor children; B) a monthly automotive allowance of $450, which the Executive
is to use to obtain an automobile to be utilized for his own company needs. All
maintenance, insurance etc. (excluding fuel) will be the responsibility and
expense of the Executive; C) the cost of all continuing professional education
related courses required to maintain CPA certification.

         5. Extent of Services: The Executive shall devote a substantial portion
of business time, attention and energies to the business of the Corporation, and
shall not, during the term of this Agreement, engage in any other business
activities, whether or not such activities are pursued for gain, profit or other
pecuniary advantage. This provision is not meant to prevent him from A) devoting
reasonable time to civic or philanthropic activities or B) investing his assets
in such form or manner providing that it does not require any substantial
services on the part of the Executive that will interfere with the Executive's
employment pursuant to this Agreement. Executive's employment is considered as
full-time.

         6. Working Facilities: The Executive shall be furnished with such
facilities and services suitable to his position and adequate for the
performance of his duties.

         7. Duties: The Executive is employed in an executive and supervisory
capacity and shall perform such duties consistent herewith as the Board of
Directors of the Corporation shall from time


<PAGE>   3

to time specify. Subject to the provisions of Section 14 hereof, the precise
services of the Executive may be extended or curtailed, from time to time, at
the discretion of the Board of Directors of the Corporation.

         8. Disclosure of Information: The Executive recognizes and acknowledges
that the Corporation's operating procedures or service techniques are valuable,
special and unique assets of the Corporation's business. The Executive will not,
during or after the term of his employment, disclose the list of the
Corporation's operating procedures or service techniques to any person, firm,
corporation, association or other entity for any reason or purpose whatsoever.
In the event of breach or threatened breach by the Executive of the provisions
of this paragraph, the Corporation shall be entitled to an injunction
restraining any such breach. Nothing herein shall be construed as prohibiting
the Corporation from pursuing any other remedies available to the Corporation
for such breach or threatened breach, including the recovery of damages from the
Executive.

         9. Vacations: The Executive shall be entitled each year to a vacation
in accordance with the vacation policy of the Corporation.

         10. Disability: If the Executive is unable to perform his services by
reason of illness or total incapacity, based on standards similar to those
utilized by the U.S. Social Security Administration, he shall receive his full
salary for one (1) year of said total incapacity through coordination of
benefits with any existing disability insurance program provided by the
Corporation ( a reduction in salary by that amount paid by any Corporation
provided insurance). Should said Executive be totally incapacitated beyond a
one-year period, so that he is not able to devote full time to his employment
with said Corporation, then this Agreement shall terminate.

         11. Death During Employment: If the Executive dies during the term of
employment and has not attained the age of seventy years, the Corporation and/or
any third party insurance provided



<PAGE>   4

by the Corporation, through a coordination of benefits, shall pay the estate of
the Executive a death benefit equal to two times the Executive's annual salary.
In the event the Executive receives death benefits payable under any group life
insurance policy issued to the Corporation, the Corporation's liability under
this clause will be reduced by the amount of the death benefit paid under such
policy. The Corporation shall pay any remaining death benefits to the estate of
the Executive over the course of twelve (12) months in the same manner and under
the same terms as the Executive would have been paid if he had still been
working for the Corporation. No later than one (1) month from the date of death,
the estate of the Executive will also be paid any accumulated vacation pay. Such
payments pursuant to this paragraph shall constitute the full compensation of
said Executive and he and his estate shall have no further claim for
compensation by reason of his employment by the Corporation.

         12. Assignment: The acts and obligations of the Corporation under this
Agreement shall inure to the benefit of and be binding upon the successors and
assigns of the Corporation.

         13. Invalidity: If any paragraph or part of this Agreement is invalid,
it shall not affect the remainder of this Agreement but the remainder shall be
binding and effective against all parties.

         14. Additional Compensation: If during the Term, this Agreement is
terminated by the Corporation (other than pursuant to the provisions of Section
15 hereof) or by the Executive due to "Constructive Discharge" then the
Executive shall receive termination pay in an amount equal to 2.99 times the
Minimum Rate. For purposes of this Agreement, "Constructive Discharge" shall
mean:

               o Any reduction in salary below the Minimum Rate;

               o A material change diminishing the Executive's job function,
               authority, duties or responsibilities, or a similar change
               deteriorating Executive's working conditions that would not be in
               accordance with the spirit of this Agreement;


<PAGE>   5
               o A required relocation of Executive of more than 35 miles from
               Executive's current job location; or requires Executive to travel
               away from Executive's office in the course of discharging
               Executive's responsibilities in excess of that typically required
               of executives in similar positions.

               o Any breach of any of the terms of this Agreement by the
               Corporation which is not cured within 14 days following written
               notice thereof by Executive to the Corporation.

The amount payable by the Corporation pursuant to this Section 14 shall be made
in one lump sum cash payment payable to the Executive no later than 30 days
following termination of this Agreement.

         15. Termination: The Corporation cannot terminate this agreement except
for: 1) the intentional, unapproved misuse of corporate funds, 2a) professional
incompetence (i.e. the intentional refusal to perform or the inability to
perform the duties associated with Executive's position with the Corporation in
a competent manner, which is not cured within 15 days following written notice
to Executive) or 2b) willful neglect of duties or responsibilities in either
case not otherwise related to or triggered by the occurrence of any event or
events described in or prescribed by Section 14 hereof.

         16. Indemnification: The Corporation hereby agrees to indemnify and
hold the Executive harmless from any loss for any corporate undertaking, as
contemplated in Section 7 hereof, whereby a claim, allegation or cause of action
shall be made against the Executive in the performance of his contractual duties
except for willful illegal misconduct. Said indemnification shall include but
not be limited to reasonable cost incurred in defending the Executive in his
faithful performance of contractual duties.
