                                          1



                                     ARTICLE III

                                       BENEFITS

    3.01  BENEFITS.  During the Term, the Employee shall be entitled to

                                      ARTICLE IV

                            TERMINATION; DEATH; DISABILITY

    4.01  TERMINATION OF EMPLOYMENT WITH CAUSE; RESIGNATION.  If the Employee
(a) breaches any material provision of this Agreement and such breach is not
remedied within thirty (30) days after written notice thereof from the Company;
or (b) has been convicted of any felony, or (c) has been convicted of any act of
fraud, misappropriation of funds or embezzlement, 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 pay accrued but unpaid
Base Salary and vacation time as of the date of termination.  If the Employee
resigns, this Agreement shall  immediately terminate and the Company shall have
no further liability or obligation to Employee hereunder or otherwise in respect
of his employment, other than its obligation to pay accrued but unpaid Base
Salary and vacation time as of the date of resignation.

    4.02  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; 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 Employee one-twelfth
(1/12) of the Base Salary in effect as of the date of such termination (the
"Severance Payments") for a period not to exceed the lesser of (i) the remainder
of the initial term of this Agreement or (ii) eighteen months (the "Severance
Period"), with the first payment being made on the thirtieth (30th) day
following such date of


                                          2



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 six months following the date of such termination without cause,
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 or (ii) the Employee
enters into direct or indirect competition with Employer, as set forth in
Section 5.03.  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)  Notwithstanding the foregoing, if any amounts due to Employee pursuant
to this Agreement are determined to be "Parachute Payments" as such term is
defined in Section 280G of the Internal Revenue Code of 1986, as amended (the
"Code"), and the regulations promulgated thereunder, then the total compensation
paid to Employee pursuant to this Agreement, together with any other payment or
the value of any benefit received or to be received by the Employee which is
treated as a Parachute Payment shall not exceed 2.99 times the Employee's Base
Amount (as such term is defined in Section 280G of the Code).  In the event a
reduction of the payments set forth in this Agreement is required pursuant to
this Section, the Employee may select the compensation which will be reduced in
order to fall within the 2.99 times Base Amount limitation.

    4.03  DEATH; DISABILITY.  The 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


                                          3



         (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.

    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, as determined in good faith by the Board of
Directors of the Company.

    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.

                                      ARTICLE V

his employment by the Company, whether or not patentable and whether or not
conceived, developed, invented, made or found on the Company's time or with the
use of the Company's facilities or materials, shall be the property of the
Company and shall be promptly and fully disclosed by the Employee to the
Company.  The Employee shall perform all necessary acts (including, without
limitation, executing and delivering any confirmatory assignments, documents or
instruments requested by the Company) to vest title to any such Inventions in
the Company and to enable the Company, at its expense, to secure and maintain
domestic and/or foreign patents or any other rights for such Inventions.

    5.02  NON-DISCLOSURE.  The Employee shall not, at any time during the Term

procedure used by the Company which is not, specifically, a matter of public
knowledge; or (b) any information relating to the operations or financial status
of the Company (including, without limitation, all financial data and sources of
financing), which information is not specifically a matter of public knowledge;
or (c) any information of a confidential nature obtained as a result of his
present or future relationship with the Company, which information is not
specifically a matter of public knowledge; or (d) the name, address or other
information relating to any customer or supplier


                                          4



of the Company; or (e) any other trade secrets of the Company.  Promptly upon
the expiration or termination of the Employee's employment hereunder for any
reason, the Employee (or his personal representative's as the case may be) shall

records and other data (including all copies) constituting or pertaining in any
way to any of the foregoing information.

    5.03  NON-SOLICITATION.  The Employee shall not, during the Term, and for

to disrupt Employer's business relationship with its customers or suppliers or
solicit any of the employees of Employer to leave the employ of Employer.

    5.04  NON-COMPETITION.  Upon the termination of this Agreement pursuant to
the terms hereof or pursuant to any right of cancellation or termination
provided herein, or for any other reason whatsoever, Employee will not engage in
any business in competition with that of Employer within any state or territory
of the United States in which Employer is doing business or has actually
investigated doing business, nor directly or indirectly perform services for any
person, firm or corporation engaged in such a competitive business in such

employment.

    5.05  BREACH OF PROVISIONS.  If the Employee breaches any of the provisions

available to the Company at law or in equity, the Company shall be entitled to
immediate injunctive relief in any court, domestic or foreign, having the
capacity to grant such relief, to restrain any such breach or threatened breach
and to enforce the provisions of this Article V.  The Employee acknowledges and
agrees that there is no adequate remedy at law for any such breach or threatened
breach and, in the event that any action or proceeding is brought seeking
injunctive relief, the Employee shall not use as a defense thereto that there is
an adequate remedy at law.
