3.       Termination.

         a.       Disability of the Executive. In the event of your incapacity
or inability to perform your services as contemplated herein for an aggregate of
ninety (90) days during any twelve (12) month period due to the fact that your
physical or mental health shall have become impaired so as to make it impossible
for you to perform the duties and responsibilities contemplated for you
hereunder, the Corporation shall have the right to declare, upon two (2) weeks
prior written notice rendered to you, a disability termination, whereupon you
shall receive (if you are entitled thereto) the short and/or long-term
disability benefits provided by the Corporation. In the event you have commenced
receiving benefits under the Corporation's disability plans, until termination
of your employment under Section 3(a), the Corporation shall not be obligated to
pay to you with regard to Base Salary an amount greater than the difference
between your Base Salary then in effect and any such disability benefits you are
then receiving.

         b.       Death of the Executive. In the event you die during your
Employment hereunder, your Employment shall automatically terminate without
notice on the date of your death, except that your estate shall receive the
death benefits, if any, provided by the Corporation.

         c.       Termination by the Corporation for Cause. Nothing herein shall
prevent the Corporation from terminating your Employment for Cause (as defined
below). From and after the date of such termination, you shall no longer be
entitled to receive the Base Salary or any other compensation which would have
otherwise been due and all Options shall terminate immediately. Any rights and
benefits that you may have in respect to any other compensation or any employee
benefit plans or programs of the Corporation shall be determined in accordance
with the terms of such other compensation arrangements, plans or programs, and
in any event, you shall have no rights or benefits under any arrangement, plan
or program unless such arrangement, plan or program is in writing and you are
specified as a participant therein. The term "for Cause", as used herein, shall
mean (i) the Executive's willful misconduct, gross negligence or dishonesty in
the performance of his duties on behalf of the Corporation, (ii) the willful
neglect, failure or refusal of the Executive to carry out any reasonable request
of the Board of Directors or President/Chief Executive Officer of the
Corporation consistent with the obligations of Executive contemplated hereunder,
(iii) the material breach of any provision of this letter by the Executive or
(iv) the entering of a plea of guilty or nolo contendere to, or the Executive's
conviction of, a felony or other crime involving moral turpitude, dishonesty,
theft or unethical business conduct. Termination of employment pursuant to this
Section 3(c) shall be made to the Executive by, and be effective upon, written
notice from the President/Chief Executive Officer or the Board of Directors.

         d.       All Other Terminations by the Company.

                  (1)      Notwithstanding the foregoing, the Corporation may
terminate your employment at any time. Subject to (2) below, if your employment
is terminated for any reason other than "for Cause", death or disability, you
shall continue to receive your current Base Salary and benefits for a period of
one (1) year from the date of such termination.

                  (2)      If the Executive is "constructively terminated" by
the Company prior to July 25, 2000 for reasons other than for Cause, and if the
Executive elects, within thirty (30) days, not to accept the new position, the
Executive shall continue to receive his current Base Salary and benefits for a
period of six (6) months. For purposes of this Agreement, constructive
termination shall be considered to occur if the Company demotes the Executive
from his present position (including to his position held prior to

                  (3)      If the Executive is "constructively terminated" by
the Company anytime on or after July 25, 2000 for reasons other than for Cause,
the Executive will be eligible to receive one (1) year of severance payable at
the highest base salary held by the Executive during his employment, as well as
the continuation of his health insurance benefits during this severance period.
