<PAGE>

                  3.3 The Company,  by notice to Executive,  may terminate  this
Agreement if Executive  shall fail because of illness or  incapacity  to render,
for six  consecutive  months,  services of the  character  contemplated  by this
Agreement.  Notwithstanding such termination,  the Company shall continue to pay
to Executive  his Salary under  Section 2.1 hereof  through the period ending on
the  earlier  of the  Termination  Date  or the  six-month  anniversary  of such
termination.

                  3.4 The Company,  by notice to Executive,  may terminate  this
Agreement and Executive's employment with the Company for cause. As used herein,
"cause"  shall  mean:  (a) the  refusal  or failure  by  Executive  to carry out
specific legal directions of the Chairman of the Board or President which are of
a material nature and consistent with his status as Chief Strategy  Officer,  or
the refusal or failure by  Executive to perform a material  part of  Executive's
duties  hereunder;  (b)  fraudulent  or  dishonest  action by  Executive  in his
relations with the Company or any of its subsidiaries or affiliates, or with any
customer  or  business  contact  of the  Company or any of its  subsidiaries  or
affiliates  ("dishonest" for these purposes shall mean Executive's  knowingly or
recklessly  making of a  material  misstatement  or  omission  for his  personal
benefit);  or (c) the  conviction of Executive of any crime  involving an act of
moral turpitude. Notwithstanding the foregoing, no "cause" for termination shall
be deemed to exist with  respect to  Executive's  acts  described  in clause (a)
above,  unless  the  Company  shall  have  given  written  notice  to  Executive
specifying the "cause" with reasonable  particularity  and, within five business
days after such notice, Executive shall not have cured or eliminated the problem
or thing giving rise to such "cause;" PROVIDED, HOWEVER, that a breach of clause
(a) above,  involving the same or  substantially  similar actions or conduct for
which the Company  previously  gave notice of  termination  and with  respect to
which,  Executive  satisfactorily  cured,  shall


                                       5

<PAGE>

be grounds for  termination  for cause  without any  additional  notice from the
Company.  Notwithstanding such termination,  the provisions of paragraph 4 shall
survive.

                  3.5 In the event of the  termination  of this Agreement by the
Company for any reason other than for "cause" (as defined in Section 3.4 above),
death (as provided in Section 3.2) or  disability  (as provided in Section 3.3),
the Company  shall  continue to pay to Executive  his Salary  under  Section 2.1
hereof for the remainder of the Employment Term. Additionally, the Company shall
continue to provide Executive with insurance under the Company's group insurance
plan or plans (as such plan or plans may be modified,  changed or replaced  from
time to time) to the extent that t is  permitted  by the plan or plans and under
applicable law. If the Company is unable to continue Executive under the plan or
plans,  the Company shall pay to Executive  each month that amount that it would
have been paying for such  participation  (had  Executive  been  employed by the
Company) through the Employment Term.

                  3.6 If, for any reason (i) Executive terminates his employment
with the Company,  or (ii) the Company terminates  Executive's  employment under
the terms of this  Agreement,  or (iii) this  Agreement  expires  without  being
renewed or extended,  then Executive  will resign as a director,  effective upon
the occurrence of such termination or expiration, whichever is applicable.

         4.       Protection of Confidential Information; Non-Competition.

                  4.1      Executive acknowledges that:


                                       6

<PAGE>

                  (a) As a result of his employment with the Company,  Executive
will obtain secret and confidential  information  concerning the business of the
Company and/or its subsidiaries and affiliates (referred to collectively in this
paragraph  4  as  the  "Company"),   including,  without  limitation,  financial
information, designs and other proprietary rights, trade secrets and "know-how,"
customers, sources and business methodologies ("Confidential Information").

                  (b) The Company will suffer  substantial  damage which will be
difficult to compute if, during the period of his employment with the Company or
thereafter,  Executive  should enter a business  competitive with the Company or
divulge Confidential Information.

                  (c)  The  provisions  of this  Agreement  are  reasonable  and
necessary for the protection of the business of the Company.

         4.2  Executive  agrees that he will not at any time,  either during the
term of this Agreement or two years thereafter,  divulge to any person or entity
any  Confidential  Information  obtained  or  learned  by him as a result of his
employment with, or prior retention by, the Company, except (i) in the course of
performing  his  duties  hereunder;  (ii)  with the  Company's  express  written
consent;  (iii) to the extent that any such  information is in the public domain
other  than  as a  result  of  Executive's  breach  of any  of  his  obligations
hereunder;  or (iv) where  required to be disclosed by court order,  subpoena or
other  government  process.  If Executive  shall be required to make  disclosure
pursuant to the provisions of clause (iv) of the preceding  sentence,  Executive
promptly,  but in no event more than 72 hours after  learning of such  subpoena,
court order, or other government process,  shall notify, by personal delivery or
by  electronic  means,  confirmed  by mail,  the Company  and, at the  Company's
expense,  Executive  shall:  (a) take all reasonably  necessary and


                                       7

<PAGE>

lawful steps required by the Company to defend  against the  enforcement of such
subpoena, court order or other government process, and (b) permit the Company to
intervene and participate with counsel of its choice in any proceeding  relating
to the enforcement thereof.

                  4.3 Upon  termination  of his  employment  with  the  Company,
Executive will promptly  deliver to the Company all memoranda,  notes,  records,
reports,  manuals,  drawings,  blueprints  and other  documents  (and all copies
thereof)  relating to the  business of the Company and all  property  associated
therewith,  which he may then  possess  or have  under  his  control;  provided,
however, subject to Executive's obligations under this Section 4, that Executive
shall be entitled to retain  copies of such  documents  reasonably  necessary to
document his financial relationship (both past and future) with the Company.

                  4.4  During  the  one-year  period  following  termination  of
Executive's employment with the Company for any reason,  Executive,  without the
prior  written  permission  of the  Company,  shall not,  anywhere in the United
States,  directly or indirectly (i) employ or retain, or have or cause any other
person or entity to employ or retain, any person who was employed or retained by
the Company in the six-month  period prior to the expiration of the  Executive's
employment  hereunder;  or (ii) solicit,  interfere  with, or endeavor to entice
away from the Company,  for the benefit of a  Competitive  Business,  any of its
customers or other persons with whom the Company has a contractual  relationship
or is  otherwise  doing  business or has done  business  during the term of this
Agreement.  Notwithstanding  the  foregoing,  nothing  in this  Agreement  shall
preclude  Executive from investing his personal  assets in the securities of any
corporation or other business entity which is engaged in a Competitive  Business
if  such  securities  are  traded  on  a  national  stock  exchange  or  in  the
over-the-


                                       8

<PAGE>

counter  market  and if such  investment  does not  result  in his  beneficially
owning, at any time, more than 4.9% of the publicly-traded  equity securities of
such Competitive Business.


                  4.4 If  Executive  commits a breach,  or threatens to commit a
breach,  of any of the provisions of Sections 4.2, 4.4 or 4.5, the Company shall
have the right and remedy:

                          (a)  to  have  the   provisions   of  this   Agreement
specifically  enforced  by  any  court  having  equity  jurisdiction,  it  being
acknowledged and agreed by Executive that the services being rendered  hereunder
to the Company are of a special, unique and extraordinary character and that any
such breach or threatened  breach will cause  irreparable  injury to the Company
and that money damages will not provide an adequate remedy to the Company; and

                          (b) to require  Executive  to account for and pay over
to the Company all monetary damages suffered by the Company as the result of any
transactions constituting a breach of any of the provisions of Sections 4.2, 4.4
or 4.5, and Executive  hereby agrees to account for and pay over such damages to
the Company.

                  Each of the rights and remedies enumerated in this Section 4.6
shall be independent of the other, and shall be severally enforceable,  and such
rights  and  remedies  shall be in  addition  to,  and not in lieu of, any other
rights and remedies available to the Company under law or equity.

                  In connection with any legal action or proceeding  arising out
of Section  4.5,  the  prevailing  party in such action or  proceeding  shall be
entitled to be reimbursed by the other party for the reasonable  attorneys' fees
and costs incurred by the prevailing party.

                  4.5 If  Executive  shall  violate any  covenant  contained  in
Section  4.4 or 4.5,  the  duration  of  such  covenant  so  violated  shall  be
automatically  extended  for a  period  of  time  equal  to the  period  of such
violation.

                  4.6 If any provision of Sections 4.2, 4.4 or 4.5 is held to be
unenforceable because of the scope,  duration or area of its applicability,  the
tribunal  making such  determination  shall have the power to modify such scope,
duration,  or area, or all of them, and such provision or provisions  shall then
be applicable in such modified form.

                  4.7 The  provisions  of this  paragraph  4 shall  survive  the
termination of this Agreement for any reason.

         5.       Definitions.
