              -------------- 

              The term of this Agreement shall be the five-year period
commencing on May 29, 1996 (the "Employment Date") and ending on the fifth
anniversary of the Employment Date (the "Agreement Term").

          2.  Employment.
              ---------- 

              (a)  Employment by the Company. Executive agrees to be employed by
                   ------------------------- 
the Company for the Agreement Term upon the terms and subject to the conditions
set forth in this Agreement. Executive shall have the title, and report to the
person or persons, specified on the Exhibit to this Agreement. Executive shall
have such duties as may be prescribed by the Company and shall serve in such
other and/or additional position(s) as the Company may determine from time to
time. Executive, if appointed to the Board of Directors of the Company and, for
no additional compensation, agrees to serve for so long as the Company shall
request. The Company will at all times treat the Executive with dignity, honesty
and respect, and will provide Executive with such resources as in the Company's
judgement shall enable the Executive to discharge his responsibilities.



              (a)  Performance of Duties. Throughout the Agreement Term,
                   ---------------------
Executive shall faithfully and diligently perform Executive's duties in
conformity with the directions of the Company and serve the Company to the best
of Executive's ability. Executive shall devote Executive's entire working time,
attention and energies to the business and affairs of the Company, subject to
vacations and sick leave as provided herein and in accordance with Company
policy.

Company may determine and, in this regard, Executive shall maintain Executive's
personal residence in such city or such other location within reasonable access
to Executive's place of employment.

 
          1.  Compensation and Benefits.
              ------------------------- 

              (a)  Base Salary.  The Company agrees to pay to Executive for
                   -----------                                             
employment hereunder a base salary ("Base Salary") at the annual rate of
$225,000.  The Base Salary shall be increased prospectively on each anniversary
of the Employment Date during the Agreement Term, by such amount as the Board of
Directors of the Company shall determine is necessary and appropriate to give
effect to increases in the cost of living.  The Base Salary shall be payable in
installments consistent with the Company's payroll practices then in effect.

              (b)  Benefits and Perquisites; Bonus. Executive shall be entitled
                   -------------------------------
to participate in, to the extent Executive is otherwise eligible under the terms
thereof, the benefit plans and programs, including medical and savings and
retirement plans, and receive the benefits and perquisites, generally provided
to employees of the same level and responsibility as Executive. Executive shall
be entitled to four weeks vacation during each year of the Agreement Term.
Nothing in this Agreement shall preclude the Company from terminating or
amending from time to time any employee benefit plan or program. Executive shall
be eligible for bonuses, at such times and in such amounts as shall be
determined at the discretion of the Board of Directors of the Company based on
their assessment of Executive's performance of his duties and on the financial
performance of the Company. The Company shall obtain life insurance coverage
(assuming the Executive is insurable) on the life and for the benefit of the
Executive in an amount equal to twice the amount of the Base Salary then in
effect. The Company shall be entitled to all dividends, if any, which may be
paid under the policy. The Executive represents that the Executive is currently
in good health.

              (c)  Travel and Business Expenses; Car Allowance. Upon submission
                   -------------------------------------------  
of itemized expense statements in the manner specified by the Company, Executive
shall be entitled to reimbursement for reasonable travel and other reasonable
business expenses duly incurred by Executive in the performance of Executive's
duties under this Agreement in accordance with the policies and procedures
established by the Company from time to time for employees of the same level and
responsibility as Executive.

              (d)  Grant of Option and Terms Thereof.  The Company hereby agrees
                   ---------------------------------                            
that, on the date hereof, it will grant to Executive, pursuant to the Company's
1992 Stock Option Plan, as amended (the "Plan"), an option (the "Option") to
purchase up to Two Hundred Fifty Thousand (250,000) shares of the Company's
common stock (the "Option Shares").  The exercise price for each Option Share
will be the closing price of the Company's common stock as reported in the Wall
Street Journal for the Employment Date.  The Option will vest and become
exercisable over a four-year period commencing on the date of grant, with one-
fifth vesting and becoming exercisable on the date of grant and on each of the
first, second, third and fourth anniversaries of the date of grant, subject to
termination as provided for in the Plan, and further subject to termination in
the event that (i) Executive breaches any term hereof, (ii) Executive's
employment hereunder is terminated by the Company for Cause (as hereinafter
defined), or (iii) Executive voluntarily terminates his employment hereunder.
The Option will expire as to each installment 

                                      -2-

 
five years from the date of vesting. The terms (including exercisability) of the
Option shall otherwise be governed by the Plan, as well as the applicable option
agreement to be entered into pursuant to the terms of the Plan. Notwithstanding
the foregoing, if a Change of Ownership (as hereinafter defined) of the Company
occurs, then, upon such occurrence, the vesting schedule of the Option shall
accelerate by two years so that three-fifths of the Option will have vested on
the Employment Date and the remaining two-fifths will vest in equal amounts on
the first and second anniversaries of the Employment Date. For purposes of the
preceding sentence, "Change of Ownership" means acquisition and control of at
least 51% of the Company's outstanding voting securities by a single entity.

              (e)  No Other Compensation or Benefits; Payment. The compensation
                   ------------------------------------------   
and benefits specified in Sections 3 and 5 of this Agreement shall be in lieu of
any and all other compensation and benefits. Payment of all compensation and
benefits to Executive hereunder shall be made in accordance with the relevant
Company policies in effect from time to time, including normal payroll
practices, and shall be subject to all applicable employment and withholding
taxes.

              (f)  Cessation of Employment. In the event Executive shall cease
                   -----------------------   
to be employed by the Company for any reason, then Executive's compensation and
benefits shall cease on the date of such event, except as otherwise provided
herein or in any applicable employee benefit plan or program.

          2.  Exclusive Employment; Noncompetition.
              ------------------------------------ 

              (a)  No Conflict; No Other Employment.  During the period of
                   --------------------------------                       
Executive's employment with the Company, Executive shall not engage in any
activity which conflicts or interferes with or derogates from the performance of
Executive's duties hereunder nor shall Executive engage in any other business
activity, whether or not such business activity is pursued for gain or profit,
except as approved in advance in writing by the Board of Directors of the
Company.

              (b)  No Competition. Without limiting the generality of the
                   --------------   
provisions of Sections 2(b) or 4(a), during the period of Executive's employment
with the Company, and for a period of two years thereafter (the "Restricted
Period"), Executive shall not, directly or indirectly, own, manage, operate,
join, control, participate in, invest in or otherwise be connected or associated
with, in any manner, including as an officer, director, employee, partner,
stockholder, joint venturer, lender, consultant, advisor, agent, proprietor,
trustee or investor, any Competing Business located in the United States or in
any other location where the Company operates or sells its products or services;
provided, however, that if Executive's employment hereunder is terminated by the
Company under Section 5(d), then the provisions of this Section 4(b) shall
remain in effect only if the Company shall not have breached its obligation to
pay to Executive amounts as severance pursuant to Section 5(d).

                                      -3-

 
                   (i)     As used in this Agreement, the term "Competing
     Business" shall mean any business or venture which engages in any business
     area, or sells or provides products or services that compete or overlap
     with any business area, in which the Company engages or is actively
     developing products or technology to engage in at any time during the
     Agreement Term, or any business or venture which sells or provides products
     or services that compete or overlap with the products or services as sold
     or provided, or are being actively developed to be sold or provided, by the
     Company at any time during the Agreement Term.

                   (ii)    For purposes of this Section 4(b), the term "invest"
     shall not preclude an investment in not more than one percent (1%) of the
     outstanding capital stock of a corporation whose capital stock is listed on
     a national securities exchange or included in the NASDAQ Stock Market, so
     long as Executive does not have the power to control or direct the
     management of, or is not otherwise associated with, such corporation.

              (c)   No Solicitation. During the Restricted Period, Executive
                    ---------------
shall not solicit or encourage any employee or consultant of the Company to
leave the employ, or cease his or her relationship with, the Company for any
reason, nor employ or retain such an individual in a Competing Business or any
other business.

              (d)   Company Customers. Executive shall not, during the
                    -----------------   
Restricted Period, directly or indirectly, contact, solicit or do business with
any "customers" (as hereinafter defined) of the Company for the purpose of
selling or providing any product or service then sold or provided by the Company
to such customers or being actively developed to be sold or provided to such
customers during Executive's employment by the Company or at the time of
termination of Executive's employment hereunder.

              For the purposes of the provisions of this Section 4(d),
"customer" shall include any entity that purchased any product or service from
the Company within twelve months of the termination of Executive's employment
hereunder, without regard to the reason for such termination. The term
"customer" also includes any former customer or potential customer of the
Company which the Company has solicited within twelve months of such
termination, for the purpose of selling or providing any product or service then
sold or provided, or then actively being developed to be sold or provided, by
the Company.

              (e)   Modification of Covenants. The restrictions against
                    -------------------------       
competition set forth in this Section 4 are considered by the parties to be
reasonable for the purposes of protecting the business of the Company. However,
if any such restriction is found by any court of competent jurisdiction to be
unenforceable because it extends for too long a period of time or over too great
a range of activities or in too broad a geographic area, it shall be interpreted
to extend only over the maximum period of time, range of activities or
geographic area as to which it may be enforceable.

                                      -4-

Confidential Information, among other things, may be prejudicial to the
Company's interests, an invasion of privacy and an improper disclosure of trade
secrets.  Executive shall not, directly of indirectly, use, make available,
sell, disclose or otherwise communicate to any corporation, partnership,
individual or other third party, other than in the course of Executive's
assigned duties and for the benefit of the Company, any Confidential
Information, either during the Agreement Term or thereafter.  In the event
Executive desires to publish the results of Executive's work for or experiences
with the Company through literature, interviews or speeches, Executive will
submit requests for such interviews or such literature or speeches to the Board
of Directors of the Company at least fourteen (14) days before any anticipated
dissemination of such information for a determination of whether such disclosure
is in the best interests of the Company, including whether such disclosure may
impair trade secret status or constitute an invasion of privacy.  Executive
agrees not to publish, disclose or otherwise disseminate such information
without the prior written approval of the Board of Directors of the 

                                      -7-

employment by the Company, either solely or jointly with others (collectively,
"Developments"). All such Developments shall be the sole property of the

Term of a special, unique, unusual, extraordinary and intellectual character,
thereby giving this Agreement peculiar value, and, in the event of a breach or

such rights and remedies by a party shall in no way preclude such party from
pursuing, at the same time or subsequently, any and all other rights and
remedies available to it.

commence to run from the date of receipt on the return receipt of the notice,
request, consent or approval by the addressee thereof. Rejection or other
refusal to accept, or the inability to deliver because of changed address of

the notice, request, consent or approval sent.

          (m)   Assistance in Proceedings, Etc.  Executive shall, without
                ------------------------------

respective obligations of Executive and rights and benefits afforded to the
Company as provided in this Agreement shall survive cessation or termination of
Executive's employment hereunder. This Agreement shall not terminate upon, and
shall remain in full force and effect following, expiration of the Agreement
Term and all rights and obligations of the parties hereto as and to the extent
provided herein shall survive such expiration.

     IN WITNESS WHEREOF, the Company has caused this Agreement to be duly
executed on its behalf by an officer thereunto duly authorized and Executive has
duly executed this Agreement, all as of the date and year first written above.
