duties and responsibilities hereunder, upon the presentation of proper accounts
therefor in accordance with the Company's policies.

         5.       Other Benefits.

   3

Company shall pay to the Executive the base salary provided for in Section 3.1
accrued to the date of such termination and not previously paid to the
Executive. The Company shall also pay to the Executive any bonus which shall be
or become payable to the Executive under Section 3.2 with respect to any fiscal
year of the Company ended prior to the date of such termination. For purposes
hereof, "Due Cause" means (a) a material breach of any of the Executive's
obligations hereunder (it being understood that any breach of the provisions of
Sections 2, 7 or 8 hereof shall be considered material); (b) willful failure to
carry out his duties hereunder, or gross misconduct; or (c) that the Executive

Executive of the grounds for such termination and, if such grounds are
susceptible to cure, shall provide Executive Thirty (30) days during which to
cure any such grounds. If Executive shall fail during such period to cure the
grounds, Executive's termination shall be effective as of the date of the notice
provided hereunder. Rights and benefits of the Executive or his transferee (a)
with respect to the Options shall be determined in accordance with Section 3.3
and (b) under the benefit plans and programs of the Company shall be determined
in accordance with the provisions of such plans and programs. After the
satisfaction of any claim of the Company against the Executive arising as a
result of such Due Cause, neither the Executive nor the Company shall have any
further rights or obligations under this Agreement, except as provided in
Sections 7, 8 and 9.

                  6.4 Termination by the Company Without Cause. The Company may
terminate the Executive's employment prior to the expiration of the term of this
Agreement for whatever reason it deems appropriate; provided, however, that in
the event that such termination is not pursuant to Sections 6.1, 6.2 or 6.3:

                           (i) The Company shall continue to pay to the 
Executive (or his estate or other legal representative in the case of the death
of the Executive subsequent to such termination), in the same periodic
installments as his base salary was paid, the base salary provided for in
Section 3.1 (at the annual rate then in effect), until the first to occur of (a)
the then scheduled expiration of the term hereof or (b) the expiration of a
period of one (1) year following such termination (the applicable period
hereinafter being referred to as the "Severance Period"); provided further, that
such periodic installment payments by the Company shall cease as of the date
Executive obtains alternative employment which does not conflict with Section
8.1(a) of this Agreement, except that, if such employment is at a rate of
compensation less than that required hereunder, Company shall continue to pay
the difference between the compensation payable under this section 6.4(i) and
the compensation Executive actually receives in his non-conflicting position for
the remainder of the Severance Period;

                           (ii)  Executive shall become fully vested in the 
Options; and

                           (iii) Executive shall continue to receive during the
Severance Period, to the extent permitted by law, the same health, disability
and life insurance benefits as Executive was receiving on the date of
termination, provided that Executive shall continue to make the same
contributions toward such coverage as Executive was making on the date of
termination, with such adjustments to contributions as are made generally for
all Executives.

                           (iv) The Executive shall receive a payment equal to
the lesser of the prior fiscal year's bonus or 50% of the current salary.

                  6.5 Rights to Benefits. Upon termination of employment under
any provision contained in this Section 6, except section 6.4, rights and
benefits of the Executive, his estate or other legal representative under the
Executive benefit plans and programs of the Company, if any, will be determined
in accordance with the terms and provisions of such plans and programs. Neither
the Executive nor the Company shall have any further rights or obligations under
this Agreement, except as provided in Sections 7, 8 and 9.



                  6.6 Termination of Employment Following a Change in Control.
Anything herein to the contrary notwithstanding, if the Executive during the one
(1) year period following a Change in Control is terminated or subjected to a
material change in the conditions of employment, including demotion, salary
reduction, reduction in



                                       3
   4

job responsibilities, or change in job location of more than 50 miles, then such
termination or material change in conditions of employment shall constitute a
termination of the Executive's employment by the Company pursuant to Section 6.4
(Termination by the Company Without Cause) and the severance amounts referred to
in paragraphs (i) and (iv) of Section 6.4 shall be paid to the Executive in a
lump sum on the date of termination. For purposes of this Agreement, a Change in
Control of the Company shall be deemed to have occurred if:6.6

                           (i) a "person" (meaning an individual, a partnership,
or other group or association as defined in Sections 13(d) and 14(d) of the
Securities Exchange Act of 1934, other than the Executive or a group including
the Executive), either (x) acquires twenty percent (20%) or more of the combined
voting power of the outstanding securities of the Company having a right to vote
in elections of directors and such acquisition shall not have been approved
within sixty (60) days following such acquisition by a majority of the
Continuing Directors (as hereinafter defined) then in office or (y) acquires
fifty percent (50%) or more of the combined voting power of the outstanding
securities of the Company having a right to vote in elections of directors; or

                           (ii) Continuing Directors shall for any reason cease
to constitute a majority of the Board of Directors of the Company; or

                           (iii) all or substantially all of the business and/or
assets of the Company are disposed of by the Company to a party or parties other
than a subsidiary or other affiliate of the Company, pursuant to a partial or
complete liquidation of the Company, sale of assets (including stock of a
subsidiary of the Company) or otherwise.

         For purposes of this Agreement, the term "Continuing Director" shall
mean a member of the Board of Directors of the Company who either was a member
of the Board of Directors on the date hereof or who subsequently became a
Director and whose election, or nomination for election, was approved by a vote
of at least two-thirds of the Continuing Directors then in office.

         7.       Confidential Information.

                  7.1 (a) The Executive shall, during the Executive's employment
with the Company and at all times thereafter, treat all confidential material
(as hereinafter defined) of the Company or any other member of the Company Group
(as hereinafter defined) confidentially. The Executive shall not, without the
prior written consent of the Chairman of the Company, disclose such confidential
material, directly or indirectly, to any party, who at the time of such
disclosure is not an employee or agent of any member of the Company Group, or
remove from the premises of the Company or any other member of the Company Group
any notes or records relating thereto, copies or facsimiles thereof (whether
made by electronic, electrical, magnetic, optical, laser, acoustic or other
means), or any other property of any member of the Company Group. The Executive
agrees that all confidential material, together with all notes and records of
the Executive relating thereto, and all copies or facsimiles thereof in the
possession of the Executive (whether made by the foregoing or other means), are
the exclusive property of the Company Group. The Executive shall not in any
manner use any confidential material of the Company Group, or any other property
of any member of the Company Group, outside of the scope of the Executive's
duties and responsibilities under this Agreement or in any way that is
detrimental to any member of the Company Group.

                      (b) For the purposes hereof, the term "confidential
material" means all information in any way concerning the activities, business
or affairs of any member of the Company Group or any of the customers or clients
of any member of the Company Group, including, without limitation, information
concerning trade secrets, together with all sales and financial information
concerning any member of the Company Group and any and all information
concerning projects in research and development or marketing plans for any
products or projects of the Company Group, and all information in any way
concerning the activities, business or affairs of any of such customers or
clients, which is furnished to the Executive by any member of the Company Group
or any of its agents, customers or clients, or otherwise acquired by the
Executive in the course of the Executive's employment with the Company;
provided, however, that the term "confidential material" shall not include
information which (i) becomes generally available to the public other than as a
result of a disclosure by the Executive, (ii) was available to



                                       4
   5

the Executive on a non-confidential basis prior to his employment with any
member of the Company Group or (iii) becomes available to the Executive on a
non-confidential basis from a source other than any member of the Company Group
or any of its agents, customers or clients, provided that such source is not
bound by a confidentiality agreement with any member of the Company Group or any
of such agents, customers or clients.

                      (c) For purposes hereof, the "Company Group" means, 
collectively, the Company and its subsidiaries.

                  7.2 Promptly upon the request of the Company, the Executive
shall deliver to the Company all confidential material in tangible form relating
to any member of the Company Group in the possession of the Executive, without
retaining a copy thereof, unless, in the opinion of counsel for the Company,
either returning such confidential material or failing to retain a copy thereof
would violate any applicable federal, state, local or foreign law, in which
event such confidential material shall be returned without retaining any copies
thereof as soon as practicable after such counsel advises that the same may be
lawfully done.

                  7.3 If Executive is required, by deposition, interrogatories,
requests for information or documents, subpoena, civil investigative demand or
similar process, to disclose any confidential material relating to any member of
the Company Group, the Executive shall provide the Company with prompt notice
thereof so that the Company may seek an appropriate protective order and/or
waive compliance by the Executive with the provisions hereof; provided, however,
that if in the absence of a protective order or the receipt of such a waiver,
the Executive is, in the opinion of counsel for the Company, compelled to
disclose confidential material not otherwise disclosable hereunder to any
legislative, judicial or regulatory body, agency or authority, or else be
exposed to liability for contempt, fine or penalty or to other censure, such
confidential material may be so disclosed.

         8.       Non-Competition.

                  8.1 The Executive acknowledges that the services to be
rendered by the Executive to the Company are of a special and unique character.
The Executive agrees that, in consideration of (a) his employment hereunder, (b)
the Company's agreement to pay severance hereunder in the event of termination
pursuant to Section 6.4 hereof and (c) the Company's agreement to vest matching
contributions in the Plan after five (5) years of participation in the Plan by
the Executive pursuant to Section 3.4 hereof, Executive shall not, (aa) prior to
one year following the date of termination of the Executive's employment by the
Company or any other member of the Company Group (i) engage, whether as
principal, agent, investor, distributor, representative, stockholder (other than
as the holder of not more than five percent (5%) of the stock or equity of any
corporation the capital stock of which is publicly traded), employee,
consultant, volunteer or otherwise, with or without pay, in any activity or
business venture, anywhere within the United States, which is competitive with
the business of the Company Group on the date of termination, (ii) solicit or
entice or endeavor to solicit or entice away from any member of the Company
Group any person who was a director, officer, employee, agent or consultant of
such member of the Company Group, either on such Executive's own account or for
any person, firm, corporation or other organization, whether or not such person
would commit any breach of such person's contract of employment by reason of
leaving the service of such member of the Company Group, (iii) solicit or entice
or endeavor to solicit or entice away any of the clients or customers of any
member of the Company Group, either on such Executive's own account or for any
other person, firm, corporation or organization, or (iv) employ any person who
was a director, officer or employee of any member of the Company Group or any
person who is or may be likely to be in possession of any confidential
information or trade secrets relating to the business of any member of the
Company Group, or (bb) at any time, take any action or make any statement the
effect of which would be, directly or indirectly, to impair the good will of any
member of the Company Group or the business reputation or good name of any
member of the Company Group, or be otherwise detrimental to the Company,
including any action or statement intended, directly or indirectly, to benefit a
competitor of any member of the Company Group.

                  8.2 The parties hereto agree that if, in any proceeding, the
court or other authority shall refuse to enforce the covenants herein set forth
because such covenants cover too extensive a geographic area or too long a
period of time, any such covenant shall be deemed appropriately amended and
modified in keeping with the intention of the parties to the maximum extent
permitted by law.

Executive set forth in this Section 8 are a material reason for the payment of

entitled to pre-judgment injunctive relief or similar equitable relief, designed
to maintain the status quo ante pending arbitration under Section 19 of this
Agreement, by restraining the Executive from committing or continuing any such
