          1. TERM OF EMPLOYMENT. The Board hereby employs the Employee as
President and CEO, and the Employee hereby agrees to serve the Corporation in
such capacity for the period commencing on September 1, 2004 (the "Effective
Date") and ending on December 31, 2007 (hereinafter referred to as the
"Employment Period"), unless sooner terminated as hereinafter provided.

          2. SCOPE OF DUTIES. The Employee shall serve as a President and CEO.

responsibilities hereunder, and except for business trips which shall be
necessary or desirable in the Corporation's business, shall render such services
at the principal office of the Corporation. Nothing herein contained or in
Section 10 hereof shall prevent or be construed as preventing the Employee from
holding or purchasing five (5%) percent or less of any class of stock or
securities of a corporation which is listed on a national securities exchange or
regularly traded in the over-the-counter market, or making other investments or
participating in business ventures not in competition with the business of the

any time during normal business hours and do not conflict with his duties or
obligations to the Corporation as provided in this Employment Agreement.

          4. DIRECT COMPENSATION. (a) In consideration for services rendered and
to be rendered by the Employee hereunder during the Employment Period, the
Employee shall receive a salary of Two Hundred and Seventy-Five Thousand
($275,000) Dollars per year, or such greater amount as the Board shall determine




from year to year based on the Employee's performance (the "Base Salary"), which
shall be paid semi-monthly in arrears or at such other intervals as other
employees are paid.

          (b) The Employee shall be entitled to receive a cash bonus (i) for the

for such period as determined by reference to the Corporation's income
statements, but without giving effect to (a) Statement of Financial Accounting

Income for the Third Bonus Period. Each bonus payable to the Employee shall be
paid within 75 days after the last day of the applicable Bonus Period. For
purposes hereof, "Applicable Percentage" shall mean (I) 1.50%, if the percentage

case may be, as determined by reference to the annual audited balance sheet of
the Corporation for the year ending as of the end of such Bonus Period
(hereinafter referred to as "Shareholders Equity") is less than or equal to 5%,

if the percentage obtained by dividing (x) the Operating Income for the Second
Bonus Period or the Third Bonus Period, as the case may be, by (y) the

3.00%, if the percentage obtained by dividing (x) the Operating Income for the
Second Bonus Period or the Third Bonus Period, as the case may be, by (y) the

          (c) Upon termination of the Employee's employment, the Corporation
shall offer the Employee the opportunity to continue the Employee's health

Employee's employment may be terminated by the Board on the occurrence of any
one or more of the following events:

          (a) The death of the Employee;

          (b) For "Cause", which shall mean (i) the willful failure by the
Employee to substantially perform his duties hereunder (including the breach of
any provision of Section 9 and/or 10 hereof), for reasons other than death or
disability; (ii) the willful engaging by the Employee in misconduct materially
injurious to the Corporation; or (iii) the commission by the Employee of an act

duties and responsibilities hereunder to the full extent required by the Board
by reason of illness, injury or incapacity for three consecutive months, or for
more than four months in the aggregate during any period of twelve calendar
months (such condition constituting "disability" for the purposes of this
Employment Agreement); provided, however, that the Corporation shall continue to
pay the Employee's then current Base Salary until the Company acts to terminate
the Employee. The Employee agrees, in the event of a dispute under this Section
6(c), to submit to a physical examination by a licensed physician selected by
the Board and consented to by the Employee.

          7. DEATH BENEFIT. In addition to all other insurance and similar death
benefits generally made available to employees of the Corporation, if the

the Employee's then current annual Base Salary at the date of death. Such death
benefit shall be payable as may be determined by the Corporation, but not less
often than six (6) equal monthly installments, payable on the last day of each
month, commencing in the month subsequent to the month in which the death
occurs.


                                       3


          8. SEVERANCE PAYMENT. (a) If the Corporation and the Employee do not
enter into a renewal agreement to be effective January 1, 2008, for a period of
at least two years and containing similar terms and conditions to those set
forth herein, then the Corporation will pay the Employee, as additional
compensation, an amount equal to the Employee's then current annual Base Salary,
as determined under Section 4(a), payable semi-monthly in arrears for the twelve
months ending December 31, 2008; such compensation is hereinafter referred to as
the "Severance Payment".

          (b) Notwithstanding the provisions of Section 8 (a) above, the
Employee will not receive the Severance Payment if,

                  (i) the Corporation declines to enter into a renewal agreement

non-compete provisions of this Employment Agreement or any other material terms
or conditions of his employment;

                   (ii) the Employee has been terminated for Cause hereunder;

                   (iii) the Employee declines to enter into a renewal agreement

          agreement for a period of not less than two years, containing similar
          terms and conditions as discussed herein; or

                   (iv) the Employee has received a change of control payment
          from the Corporation that provides change of control benefits that are
          at least equal to the amount that would be received by the Employee
          pursuant to Section 8(a) above.

          (c) If the Employee's employment is terminated for Cause, the
Corporation's sole obligation hereunder shall be to pay the Employee (i) any
accrued and unpaid Base Salary as of the date of termination, (ii) an amount
equal to such reasonable and necessary business expenses incurred by the
Employee in connection with the Employee's employment on behalf of the
Corporation on or prior to the date of termination, but not previously paid to
the Employee, and (iii) if the basis for such termination arises under clause
(i) of the definition of "Cause," his base Salary (at the rate in effect on the
date of termination) through the twelve-month anniversary of the date of
termination in accordance with the normal payroll practices of the Corporation
with respect to Base Salary.

          (d) If at the time his employment is terminated the Employee is a
"specified employee" within the meaning of Section 409A of the Internal Revenue
Code and the regulations thereunder, to the extent required to comply with
Section 409A, payment of the Severance Payment and the Non-Renewal Severance, as
applicable, shall not commence until one day after the day which is six months
following the termination date, with the first payment equaling six months of
Base Salary. Reimbursements pursuant to this Section 8 shall be made on or

other entity to whom such proprietary or confidential information, in whole or
in part, has been disclosed or is threatened to be disclosed. Nothing herein
contained 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 Employee.

          10. RESTRICTIVE COVENANTS. (a) The Employee hereby acknowledges and
recognizes the highly competitive nature of the Corporation's business and

Employment Agreement), then the "Designated Date" shall mean the second (2nd)
anniversary of the effective date of such termination;

                   (ii) if the Corporation terminates the employment of the
Employee under this Employment Agreement for Cause, then the "Designated Date"
shall be the second (2nd) anniversary of the effective date of such termination;

                   (iii) if the Corporation, during the Employment Period,

                   (iv) if the Corporation offers the Employee a renewal
agreement pursuant to Section 8(a) hereof and the Employee does not accept such
agreement, then the "Designated Date" shall mean December 1, 2009.

          (c) It is the desire and intent of the parties that the provisions of
this Section 10 shall be enforced to the fullest extent permissible under the
laws and public policies applied in each jurisdiction in which enforcement is
sought. Accordingly, if any particular provision of this Section 10 shall be
adjudicated to be invalid or unenforceable, such provision of this Section 10
shall be deemed amended to delete from the portion thus adjudicated to be
invalid or unenforceable, such deletion to apply only with respect to the
operation of such provisions of this Section 10 in the particular jurisdiction
in which such adjudication is made and, further, only to the extent required in
order for this Section 10 to be enforceable.

          (d) With respect to Inventions (including but not limited to software)

by the Corporation:

                   (i) The Employee shall inform the Corporation promptly and
fully of such Inventions by written report, setting forth in detail the
procedures employed and the results achieved. A report shall be submitted by the
Employee upon completion of any studies or research projects undertaken on the

make applications for United States and/or foreign letters patent or other

                                       6


                   (iv) The Employee shall acknowledge and deliver promptly to
the Corporation, without charge to the Corporation, but at its expense, such
written instruments and do such other acts in support of his inventorship, as
may be necessary in the opinion of the Corporation to obtain and maintain United
States and/or foreign letters patent or other registration and to vest the
entire right in such Inventions, patents and patent applications in the
Corporation. The Employee agrees that if the Corporation is unable because of
the Employee's mental or physical incapacity or unavailability or for any other
reason to secure the Employee's signature to apply for or to pursue any
application for any United States or foreign patents or copyright registrations
covering Inventions assigned to the Corporation as above, the Employee hereby
irrevocably designates and appoints the Corporation and its duly authorized
officers and agents as the Employee's agent and attorney in fact, to act for and
in the Employee's behalf and stead to execute and file any such applications and
to do all other lawfully permitted acts to further the application for,
prosecution, issuance, maintenance or transfer of letters patent or copyright
registrations thereon with the same legal force and effect as if originally
executed by the Employee. The Employee hereby waives and irrevocably quitclaims
to the Corporation any and all claims, of any nature whatsoever, which the
Employee now or hereafter may have for infringement of any and all proprietary
rights assigned to the Corporation.

                   (v) The Corporation shall also have the royalty-free right to
use in its business, and to make, use, and sell products and/or services derived
from any Inventions, discoveries, concepts and ideas, whether or not patentable,

well as improvements or know-how, whether or not within the scope of Inventions,
but which are obtained, created or made by the Employee during the Employment
Period, without payment of any additional compensation to the Employee.

                   (vi) For the purposes of this Employment Agreement,
"Inventions" means discoveries, concepts and ideas, whether patentable or not,
including but not limited to processes, methods, formulas and techniques as well
as improvements or know-how.

          (e) If there is a breach or threatened breach by the Employee of the
provisions of this Section 10, the Corporation shall be entitled to an

prohibited by any agreement or the order of any court from entering into and
carrying out the terms of this Employment Agreement. In particular, the Employee
warrants and represents that the scope of his activity is not restricted in any
