     3.  COMPENSATION.  In consideration of the services to be rendered by
Employee to the Company hereunder including compliance with the covenants and
agreements herein, the Company hereby agrees to pay or otherwise provide
Employee the following compensation and benefits, it being understood that the
Company shall have the right to deduct all taxes which may be required to be

limited to Social Security payments, income tax withholding and other required
deductions now in effect or which may become effective by law any time during
the Term):

     (a)  SALARY.  Employee shall receive an annual salary of One Hundred Fifty-

leave policy which the Company may adopt from time to time.

     4.  TERMINATION.

     (a)  DEATH OR DISABILITY.  This Agreement shall terminate automatically
upon the Employee's death. If the Company determines in good faith that the

intention to terminate the Employee's employment. In such event, the Employee's
employment with the Company shall terminate effective on the 30th day after

have returned to full-time performance of the Employee's duties. For purposes of
this Agreement, "Disability" means disability which, at least 26 weeks after its
commencement, is determined to be total and permanent by a physician selected by
the Company or its insurers and acceptable to the Employee or the Employee's
legal representative (such agreement as to acceptability not to be withheld
unreasonably).

     (b)  CAUSE.  The Company may terminate the Employee's employment for

          (i)  an act or acts of personal dishonesty taken by the Employee
at the expense of the Company;

of the Employee's obligations under Section 1 of this Agreement which are
demonstrably willful or deliberate on the Employee's part;

          (iii)  the conviction of the Employee of a felony or
misdemeanor that adversely affects the Company's business, reputation or
standing in the community;

          (iv)  repeated failure on the part of Employee to obey or carry
out reasonable directives from the Board of Directors or Employee's supervisor
which are consistent with this Agreement and pertain to Employee's employment
with the Company; or

performance within three months from the date that the Chief Executive Officer
of the Company gives Employee written notice of the specific performance
criteria which Employee is failing to meet.

     (c)  EMPLOYEE'S RIGHT TO TERMINATE.  The Employee's employment may be
terminated by the Employee for Good Reason.  For purposes of this Agreement,
"Good Reason" means:

responsibilities to be reduced from the position described in Section 1 of this
Agreement;

given by the Employee;

          (iii)     Any termination by the Company of the Employee otherwise

          (i)  indicates the specific termination provision in this
Agreement relied upon;

          (ii)  in the event of termination for Cause, sets forth in
reasonable detail the facts and circumstances claimed to provide a basis for
termination of the Employee's employment under the provision so indicated; and

          (iii)  if the Date of Termination (as defined below) is other than
the date of receipt of such notice, specifies the termination date.

     (f)  DATE OF TERMINATION.  "Date of Termination" means the date of receipt
of the Notice of Termination or the date specified therein, as the case may be;
provided, however, that:

          (i)  if the Employee' s employment is terminated by the Company
other than for Cause or Disability, the Date of Termination shall be the date on
which the Company notifies the Employee of such termination,

(90) calendar days following delivery of notice of such termination.

     5.   OBLIGATIONS OF THE COMPANY UPON TERMINATION.

     (a)  DEATH.  If the Employee's employment is terminated by reason of the
Employee's death, this Agreement shall terminate without further obligations to
the Employee's legal representatives under this Agreement, other than those
obligations accrued or earned and vested by the Employee as of the Date of
Termination, including, for this purpose

          (i)  the Employee's full Base Salary through the Date of Termination
at the rate in effect on the Date of Termination, and

                                       3
<PAGE>

          (ii)  the amount of any bonus earned by the Employee for the fiscal
year through the Date of Termination, and 

          (iii)  any compensation previously deferred by the Employee (together
with any accrued interest thereon) and not yet paid by the Company and any
accrued vacation pay not yet paid by the Company (such amounts specified in
clauses (i), (ii) and (iii) are hereinafter referred to as "Accrued
Obligations"), and

          (iv)  the right to exercise vested options to purchase the Company's
common stock in accordance with the terms and conditions of the applicable stock
option plan and stock option agreement.

All Accrued Obligations shall be paid to the Employee's estate or beneficiary,
as applicable, in a lump sum in cash within 30 days of the Date of Termination.
Notwithstanding anything in this Agreement to the contrary, the Employee's
family shall be entitled to receive benefits at least equal to the most
favorable benefits provided by the Company to surviving families of employees of
the Company under such plans, programs, practices and policies relating to
family death benefits, if any, in effect at the time of Employee's death.

     (b)  DISABILITY.  If the Employee's employment is terminated by reason of
the Employee's Disability, this Agreement shall terminate without further
obligations to the Employee, other than those obligations accrued or earned and
vested (if applicable) by the Employee as of the Date of Termination, including
for this purpose, all Accrued Obligations. All such Accrued Obligations shall be
paid to the employee in a lump sum in cash within 30 days of the Date of
Termination. Notwithstanding anything in this Agreement to the contrary, the
Employee shall be entitled after the Disability Effective Date to receive
disability and other benefits at least equal to the most favorable of those
provided by the Company to disabled employees or their families in accordance
with such plans, programs, practices and policies relating to disability, if
any, in effect at any time after the Effective Date.

     (c)  CAUSE.  If the Employee's employment shall be terminated for Cause
under clause (i), (ii), (iii) or (iv) of Section 4(b) hereof, all obligations of
the Company hereunder shall terminate other than the obligation to pay to the
Employee the Base Salary through the Date of Termination plus the amount of any
compensation previously deferred by the Employee (together with accrued interest
thereon).  If Employee's employment shall be terminated for Cause under clause
(v) of Section 4(b) hereof, all obligations of the Company hereunder shall
terminate other than the obligation to continue, in accordance with the
Company's normal payroll procedures, to pay Employee his Base Salary for a
period of six (6) months from the Date of Termination.  Following termination
for Cause, Employee shall have three (3) months to exercise any vested but 
unexercised options previously granted to Employees.

     (d)  GOOD REASON.  If Employee shall terminate his employment under Section
4(c) hereof, (i) the Company's obligations to Employee shall terminate other
than the obligation to pay the Base Salary through the Date of Termination plus
the amount of any compensation previously deferred by the Employee, if any,
consistent with Company policy, and (ii) as of the date that notice of
termination is delivered to the Company under Section 4(c), Employee shall have
three (3) months to exercise any vested but unexercised options previously
granted to Employee to purchase shares of the Company's Common Stock.

     (e)  OTHER THAN FOR CAUSE OR DISABILITY.  If, during the Term, the Company
shall terminate the Employee's employment other than for Cause, Disability, or
death, or Employee shall terminate 

                                       4
<PAGE>

for Good Reason the Company shall continue in accordance with the Company's 
normal payroll procedures to pay Employee his Base Salary for a period of 
twelve (12) months from the Date of Termination or for the remaining term of 
this Agreement, whichever period is shorter (the "Severance Period"); 
provided, however, that in no event shall the severance period be shorter 
than six (6) months.  During the Severance Period, the Company shall continue 
benefits to Employee and the Employee's family at least equal to those which 
would have been provided to them in accordance with the plans, programs, 
practices and policies described in Section 3(b) of this Agreement if the 
Employee's employment had not been terminated or provide continuation 
coverage as set forth under Part 6 of Title I of the Employee Retirement 
Income Security Act of 1974, as amended, at the option of the Board of 
Directors of the Company. 

     (f)     CHANGE OF CONTROL.  The foregoing notwithstanding, if the 
Company shall terminate Employee's employment other than for Cause, disability
or death following a Change of Control (as defined below), the Company shall 
continue in accordance with its normal payroll procedures to pay Employee his 
Base Salary for a period of eighteen (18) months from the Date of 
Termination.  A "Change of Control" shall mean a sale of substantially all of 
the common stock of the Company or a merger in which the Company is not the 
surviving corporation.

     6.   NON-EXCLUSIVITY OF RIGHTS.  Nothing in this Agreement shall prevent or
limit the Employee's continuing or future participation in any benefit, bonus,
incentive or other plans, programs, policies or practices, provided by the
Company and for which the Employee may qualify. Amounts which are vested
benefits or which the Employee is otherwise entitled to receive under any plan,
policy, practice or program of the Company at or subsequent to the Date of
Termination shall be payable in accordance with such plan, policy, practice or
program.

     7.   CONFIDENTIALITY.  Employee acknowledges that during the course of his
performance of services for the Company he will acquire knowledge with respect

innovations, improvements or discoveries relating to the business or the Company

and discoveries, whether patentable or copyrightable or not) conceived or 
made by him during his employment with the Company shall be, and hereby are, 
assigned to the Company. Employee will promptly disclose such inventions, 
ideas, innovations or improvements to the Board of Directors or Chief 
Executive Officer of the Company and perform all actions reasonably requested
