4.3.     TERMINATION OF EMPLOYMENT WITHOUT CAUSE. Notwithstanding any provision
         ---------------------------------------
         to the contrary herein, the Company may at any time, in its sole and
         absolute discretion and for any or no reason, terminate the employment
         of the Employee hereunder (change of control of 50% or more of the
         voting shares of company, through sale, merger, consolidation, or other
         transaction, shall constitute termination without cause at the election
         of the Employee) PROVIDED, that if such termination is not a
         Termination With Cause, the Company shall pay and/or provide the
         Employee as follows:

              (a)   any accrued but unpaid Base Salary as of the date of the
                    termination as and when such amount is due and payable
                    hereunder.

              (b)   provided Employee has not accepted employment with another
                    employer (as provided below), Employer shall pay monthly to

                    of the date of such termination (the "Severance Payments")
                    for a period of twelve (12) months (the "Severance Period"),
                    with the first payment being made on the thirtieth (30th)
                    day following such date of termination and with each
                    subsequent payment being made on the same day of each
                    successive month. The obligation of the Company to provide
                    the Benefits shall continue for twelve months following the
                    date of such termination or expiration without offer of
                    renewal, PROVIDED, that the Company may, at its option, pay

Severance Payments and the provision of Benefits shall terminate when (i) the
Employee has secured new employment with a base salary equal to or greater than
the Base Salary in effect as of the date of termination. If the Employee accepts
new employment with a base salary (the "New Salary") less than the Base Salary
in effect as of the date of termination and the Severance Period set forth above
has not expired, the Company, in lieu of the remaining Severance Payments to be
made, shall pay the Employee the difference between the total amount of the
remaining Severance Payments due and the total amount of New Salary payable
during the remaining applicable Severance Period.

              (c)   a cash payment immediately upon the date of termination
                    equal to the Employee's Base Salary on a daily basis
                    (computed on a 260 workday year) in effect on the date of

                                       3

                    termination multiplied by the number of accrued and unused
                    vacation days at the date of termination.

              (d)   Restricted stock and such Additional Shares as required to
                    make employee stock equal to 5% of the shares then
                    outstanding will vest upon termination.

              (e)   The provisions of article 5 below will not apply unless

         to the Employee. In the event of a termination of the Employee's
         employment for death or Disability, the Company shall pay the Employee
         (or his legal representatives, as the case may be) as follows:

              (a)   any accrued but unpaid compensation for Base Salary as of
                    the date of death or termination for Disability, as and when
                    such amounts are due and payable hereunder;

              (b)   a cash payment payable on the date of termination equal to
                    the Employee's Base Salary on a daily basis (computed on a
                    260 workday year) in effect on the date of death or
                    termination, multiplied by the number of accrued and unused
                    vacation days at the date of such termination; and

              (c)   in the event the Employee is Disabled, the Company will
                    continue to pay Base Salary and Benefits for the Employee
                    for a period of six (6) months, until and unless the
                    Employee obtains other employment with a comparable base
                    salary within such period, PROVIDED, that the Company may,
                    at its option, pay for and acquire insurance which will
                    provide to Employee the Base Salary and Benefits for the
                    duration of the Severance Period.

              (d)   Stock and Additional Shares vests pro-rata to the date of
                    death.

         For the purpose of this Agreement, the Employee shall be deemed to be
"Disabled" or have a "Disability" if he has been unable to perform his duties
hereunder for three (3) consecutive months or ninety (90) days in any twelve
(12) consecutive month period, or if a physician certifies that disability will
continue for 90 days, or if Employee has been unable to work for 150 days during
any 16 month period as determined in good faith by the Board of Directors of the
Company and in accordance with applicable laws.

         The Employee acknowledges that the payments referred to in this Section
4.03 constitute the only payments to which the Employee (or his legal
representatives, as the case may be) shall be entitled to receive from the
Company hereunder in the event of a termination of his employment for death or
Disability, and that except for such payments the Company shall have no further
liability or obligation to him (or his legal representatives, as the case may
be) hereunder or otherwise in respect of his employment.

                         TERMINATION; DEATH; DISABILITY

         10.1.  TERMINATION OF EMPLOYMENT WITH CAUSE. If the Employee (a)
                ------------------------------------
breaches any material provision of this Agreement or fails to satisfactorily
perform his obligations hereunder in a fashion that has a material and
significantly adverse effect on the operations of the Company, and such breach
and/or failure to perform is not remedied within thirty (30) days after written
notice thereof from the Company (except that any violation of Article V of this
Agreement may at the Company's discretion result in immediate termination); (b)
has been convicted of or entered a guilty plea to any felony; (c) has committed
any act of fraud, misappropriation of funds, embezzlement or any other act of
moral turpitude as determined by the Board of Directors, in good faith; or (d)
has engaged in willful, reckless, fraudulent, dishonest or grossly negligent
misconduct; then, in addition to any other remedies available to it at law, in
equity or as set forth in this Agreement, the Company shall have the right, upon
written notice to the Employee, to immediately terminate his employment (a
"Termination With Cause") hereunder, without any further liability or obligation
to him hereunder or otherwise in respect of his employment, other than its
obligation to abide by the terms of the attached Stock Restriction Agreement and
its obligation to pay accrued but unpaid Base Salary and vacation time as of the
date of termination.

                -----------
immediately terminate and the Company shall have no further liability or
obligation to Employee hereunder or otherwise in respect of his employment,

                ---------------------------------------
provision to the contrary herein, the Company may at any time, in its sole and
absolute discretion and for any or no reason, terminate the employment of the
Employee hereunder (change of control of 50% or more of the voting shares of
company, through sale, merger, consolidation, or other transaction, shall
constitute termination without cause at the election of the Employee) PROVIDED,
that if such termination is not a Termination With Cause, the Company shall pay
and/or provide the Employee as follows:

                                       2

<PAGE>

                (a)  any accrued but unpaid Base Salary as of the date of the
termination as and when such amount is due and payable hereunder.

                (b)  provided Employee has not accepted employment with another
employer (as provided below), Employer shall pay monthly to Employee one-twelfth
(1/12) of the Base Salary in effect as of the date of such termination (the
"Severance Payments") for a period of twelve (12) months (the "Severance
Period"), with the first payment being made on the thirtieth (30th) day
following such date of termination and with each subsequent payment being made
on the same day of each successive month. The obligation of the Company to
provide the Benefits shall continue for twelve months following the date of such
termination or expiration without offer of renewal, PROVIDED, that the Company
may, at its option, pay for and acquire insurance which will provide to Employee
the Benefits for the duration of the Severance Period.

         Notwithstanding the foregoing paragraph (b), the Severance Period,
Severance Payments and the provision of Benefits shall terminate when (i) the
Employee has secured new employment with a base salary equal to or greater than
the Base Salary in effect as of the date of termination. If the Employee accepts
new employment with a base salary (the "New Salary") less than the Base Salary
in effect as of the date of termination and the Severance Period set forth above
has not expired, the Company, in lieu of the remaining Severance Payments to be
made, shall pay the Employee the difference between the total amount of the
remaining Severance Payments due and the total amount of New Salary payable
during the remaining applicable Severance Period.

                (c)  a cash payment immediately upon the date of termination
equal to the Employee's Base Salary on a daily basis (computed on a 260 workday
year) in effect on the date of termination multiplied by the number of accrued
and unused vacation days at the date of termination.

                (d)  Restricted stock and such Additional Shares as required to
make employee stock equal to 5% of the shares then outstanding will vest upon
termination.

                (e)  The provisions of article 5 below will not apply unless
Employee is being paid a salary pursuant to this agreement.

         10.4.  DEATH; DISABILITY. Employee's employment hereunder shall
                -----------------
terminate (x) upon his death or (y) if the Employee becomes Disabled (as such
term is hereinafter defined), at the election of the Company by written notice
to the Employee. In the event of a termination of the Employee's employment for
death or Disability, the Company shall pay the Employee (or his legal
representatives, as the case may be) as follows:

                (a)  any accrued but unpaid compensation for Base Salary as of
the date of death or termination for Disability, as and when such amounts are
due and payable hereunder;

                (b)  a cash payment payable on the date of termination equal to
the Employee's Base Salary on a daily basis (computed on a 260 workday year) in
effect on the date of death or termination, multiplied by the number of accrued
and unused vacation days at the date of such termination; and

                (c)  in the event the Employee is Disabled, the Company will
continue to pay Base Salary and Benefits for the Employee for a period of six
(6) months, until and unless the Employee obtains other employment with a
comparable base salary within such period, PROVIDED, that the Company may, at
its option, pay for and acquire insurance which will provide to Employee the
Base Salary and Benefits for the duration of the Severance Period.

                (d)  Stock and Additional Shares vests pro-rata to the date of
death.

         For the purpose of this Agreement, the Employee shall be deemed to be
"Disabled" or have a "Disability" if he has been unable to perform his duties
hereunder for three (3) consecutive months or ninety (90) days in any twelve
(12) consecutive month period, or if a physician certifies that disability will
continue for 90 days, or if Employee has been unable to work for 150 days during

         The Employee acknowledges that the payments referred to in this Section
4.03 constitute the only payments to which the Employee (or his legal
representatives, as the case may be) shall be entitled to receive from the
Company hereunder in the event of a termination of his employment for death or
Disability, and that except for such payments the Company shall have no further
liability or obligation to him (or his legal representatives, as the case may
be) hereunder or otherwise in respect of his employment.
