                                   WITNESSETH:

     WHEREAS, the Corporation desires to retain the Employee as Senior Vice

     NOW, THEREFORE, in consideration of the mutual covenants and obligations

renewable for successive additional two (2) year terms unless at least three (3)
months prior to the initial two-year period or any subsequent two-year term the

two-year period (with such initial two year term and any two year renewal
thereof, unless sooner terminated in accordance with this Agreement being the

foregoing, the Employee hereby agrees to perform well and faithfully the
aforesaid duties and responsibilities and the other reasonable senior executive
duties and responsibilities assigned to him from time to time by the Board of
Directors of the Corporation or its designee. During the Term of the Employment,
the Corporation shall provide the Employee with an office, secretarial and other

perform the duties assigned to him hereunder.

     3. Time to be Devoted to Employment.

Employee shall devote substantially his full time and energy to the business of
the Corporation.

     (b) During the Term of Employment, the Employee shall not be engaged in any
other business activity which, in the reasonable judgment of the Corporation,
conflicts with the duties of the Employee hereunder, whether or not such
activity is pursued for gain, profit or other pecuniary advantage.

     4. Compensation; Reimbursement.

     (a) During the Term of Employment, the Corporation (or at the Corporation's

policy of the Corporation with respect to employees of the Corporation at
substantially the same employment level as the Employee, but in no event less
frequently than once per month. Thereafter, the Base Salary shall be subject to
increase at the option and in the sole discretion of the Board of Directors of
the Corporation.

     (b) Employee shall be eligible for an annual bonus as determined by the
Board of Directors of the Corporation based on Employee's performance. The bonus

     (c) Effective in 2005, Employee shall be eligible for an annual stock
option grant consistent with the Corporation's Stock Option Plan with said grant
being determined by the Board of Directors of the Corporation based on the
Corporation's performance. Upon employment the Employee will receive a stock

Corporation in the performance of his duties hereunder upon presentation by the
Employee to the Corporation of appropriate vouchers, receipts and reports.

     5. Disability or Death.

     (a) If the Employee is incapacitated or disabled by accident, sickness or
otherwise so as to render him mentally or physically incapable of performing the
services required to be performed by him under this Agreement for a period of 90

Corporation's Long Term Disability Benefits Plan pursuant to the terms and


                                       3

<PAGE>

conditions of such plan. Until the Employee becomes eligible for benefits under
the Corporation's Long Term Disability Benefits Plan and so long as the
Corporation shall not have otherwise terminated the Employee's employment
hereunder in accordance with this Agreement, the Employee shall be entitled to
receive his compensation, notwithstanding any such Disability.

     (b) If the Employee dies during the Term of Employment, his employment
hereunder shall be deemed to cease as of the date of his death.

     6. Termination For Cause. The Corporation may, with the approval of a
majority of the Board of Directors of the Corporation, terminate the employment
of the Employee hereunder at any time during the Term of Employment for "cause"
(such termination being hereinafter called a "Termination For Cause") by giving
the Employee notice of such termination, and upon the giving of such notice
termination shall take effect immediately. For the purposes of this Section 6,
"cause" shall mean (i) the Employee's actions on behalf of the Corporation or
any subsidiary or affiliate thereof, without the authorization of the Board of
Directors, Chief Executive Officer, or President & Chief Operating Officer of
the Corporation, which actions are knowingly for the pecuniary benefit of the
Employee or members of his family and which actions materially and adversely
effect the business or affairs of the Corporation or any subsidiary or affiliate
thereof, or (ii) the Employee fails in any material respect to observe and
perform his obligations hereunder or under the Employee Confidential
Information, Invention and Non-Competition Agreement by and between Employee and
Corporation which failure is not cured within twenty (20) days after written
notice thereof is given to the Employee by the Corporation, or, (iii) the
commission by the Employee of an act involving embezzlement or fraud against the
Corporation (other than non-material expense account issues) or commission or
conviction of a felony or (iv) the repeated use by the Employee of alcohol in a
manner which


                                       4

<PAGE>

impairs his duties or the use of any controlled substance other than under a
physicians prescription.

     7. Termination Without Cause. The Corporation may, with the approval of a
majority of the Board of Directors of the Corporation, terminate the employment
of the Employee hereunder at any time during the Term of Employment without
"cause" (such termination being hereinafter called a "Termination Without
Cause") by giving the Employee notice of such termination, upon the giving of
such notice, termination shall take effect immediately.

     8. Voluntary Termination. Any termination of the employment of the Employee
hereunder otherwise then as a result of an Involuntary Termination, a
Termination For Cause or a Termination Without Cause shall be deemed to be a
"Voluntary Termination". A Voluntary Termination shall be deemed to be effective
immediately upon receipt of notice to the Corporation of such termination.

     9. Effect of Termination of Employment.

     (a) Upon the termination of the Employee's employment hereunder pursuant to
a Voluntary Termination or a Termination For Cause, neither the Employee nor his
beneficiary or estate shall have any further rights or claims against the
Corporation under this Agreement except to receive:

          (i) the unpaid portion of the Base Salary provided for in Section
     4(a), computed on a pro-rata basis to the date of termination; and

          (ii) reimbursement for any expenses for which the Employee shall not
     have theretofore been reimbursed as provided in Section 5(e).


                                       5

<PAGE>

          (iii) any amounts due and owing to the Employee by the Corporation
     under any benefit plan.

     (b) Upon the termination of the Employee's employment hereunder pursuant to
Disability or death neither the Employee nor his beneficiary or estate shall
have any further rights or claims against the Corporation under this Agreement
except to receive payments equal to that provided for in Section 5(a), if
applicable, and Section 9(a) hereof and any other benefits available under the
Corporation's Benefits Plans.

     (c) Upon the termination of the Employee's employment hereunder pursuant to
a Termination Without Cause, neither the Employee nor his beneficiary or estate
shall have any further rights or claims against the Corporation under this
Agreement except to receive a termination payment equal to that provided for in
Section 9(a) hereof, plus an aggregate amount equal to twelve (12) months Base
Salary, payable in equal monthly installments and the continuation of medical
and dental benefits and life insurance for the same twelve (12) month period to
the extent such benefits were being provided to Employee at the time of
termination.
