of interest with the Company,  or upon discovery thereof,  allow such a conflict
to continue.  The Executive further agrees to disclose to the Company,  promptly
after discovery,  any facts or  circumstances  which might involve a conflict of
interest with the Company.

         7.2 The Company and the  Executive  recognize  that it is impossible to
provide an exhaustive list of actions or interests which  constitute a "conflict
of interest".  Moreover,  the Company and the Executive recognize that there are
many borderline situations.  In some instances,  full disclosure of facts by the
Executive  to the  Company is all that is  necessary  to enable  the  Company to
protect its interests. In others, if no improper motivation appears to exist and
the Company's  interests  have not suffered,  prompt  elimination of the outside
interest will suffice.  In still others,  it may be necessary for the Company to
terminate the employment relationship.  The Company and the Executive agree that
the Company's  determination  as to whether or not a conflict of interest exists
shall be conclusive.  The Company  reserves the right to take such action as, in
its judgment, will end the conflict of interest.



<PAGE>


         7.3 In this  connection,  it is  agreed  that any  direct  or  indirect
interest  in,   connection   with  or  benefit  from  any  outside   activities,
particularly  commercial  activities,  which interest might in any way adversely
affect the Company or its Affiliates,  involves a possible conflict of interest.
Circumstances in which a conflict of interest on the part of the Executive would
or might  arise,  and  which  should be  reported  immediately  to the  Company,
include, but are not limited to, the following:

         (a)  Ownership  of  a  material  interest  in  any  lender,   supplier,
contractor,  subcontractor, customer or other entity with which the Company does
business.

         (b)  Acting in any  capacity,  including  director,  officer,  partner,
consultant,  employee, distributor, agent or the like, for any lender, supplier,
contractor,  subcontractor, customer or other entity with which the Company does
business.

         (c) Acceptance,  directly or indirectly, of payments, services or loans
from a lender,  supplier,  contractor,  subcontractor,  customer or other entity
with which the Company does  business,  including,  without  limitation,  gifts,
trips,  entertainment  or  other  favors  of  more  than a  nominal  value,  but
excluding,  loans from  publicly  held  insurance  companies  and  commercial or
savings banks at market rates of interest.

         (d) Use of  information or facilities to which the Executive has access
in a manner which will be  detrimental to the Company's  interests,  such as use
for the Executive's own benefit of know-how or information developed through the
Company's business activities.

         (e)  Disclosure  or other misuse of  information  of any kind  obtained
through the Executive's connection with the Company.

<PAGE>


As part of the Executive's fiduciary duties to the Company, the Executive agrees
that  during  his  employment  by the  Company  and for a period of three  years
following the Date of  Termination,  the Executive  shall  promptly  disclose in
writing,  to  the  Company  all  information,  ideas,  concepts,   improvements,
discoveries  and  inventions,  whether  patentable  or not,  and  whether or not
reduced to practice,  which are  conceived,  developed,  made or acquired by the
Executive,  either  individually or jointly with others, and which relate to the
business, products or services of the Company or its Affiliates, irrespective of
whether the Executive used the Company's time or facilities and  irrespective of
whether such information, idea, concept, improvement, discovery or invention was
conceived,  developed,  discovered  or acquired by the  Executive on the job, at
home, or elsewhere.  This obligation extends to all types of information,  ideas
and concepts, including,  information,  ideas and concepts relating to new types
of services, corporate opportunities, acquisition prospects, the identity of key
representatives within acquisition prospect organizations,  prospective names or
service marks for the Company's business activities, and the like.

10.      OWNERSHIP OF INFORMATION,  IDEAS, CONCEPTS,  IMPROVEMENTS,  DISCOVERIES
         AND INVENTIONS AND ALL ORIGINAL WORKS OF AUTHORSHIP.

         10.1 All information,  ideas, concepts,  improvements,  discoveries and
inventions,  whether patentable or not, which are conceived,  made, developed or
acquired by the Executive or which are disclosed or made known to the Executive,
individually or in conjunction with others, during the Executive's employment by
the  Company  and which  relate to the  business,  products  or  services of the
Company or its Affiliates (including,  without limitation,  all such information
relating to corporate opportunities, research, financial and sales data, pricing
and  trading  terms,   evaluations,   opinions,   interpretations,   acquisition
prospects, the identity of customers or their requirements,  the identity of key
contacts  within the  customers'  organizations  or within the  organization  of

Company.   Furthermore,   all  drawings,   memoranda,   notes,  records,  files,
correspondence, manuals, models, specifications, computer programs, maps and all
other  writings or materials  of any type  embodying,  any of such  information,
ideas, concepts,  improvements,  discoveries and inventions are and shall be the
sole and exclusive property of the Company.


<PAGE>


         10.2 In particular,  the Executive hereby specifically sells,  assigns,
transfers  and  conveys to the  Company all of his  worldwide  right,  title and
interest  in  and  to  all  such  information,  ideas,  concepts,  improvements,
discoveries or  inventions,  and any United States or foreign  applications  for
patents,  inventor's  certificates or other industrial rights which may be filed
in respect thereof, including divisions,  continuations,  continuations-in-part,
reissues and/or  extensions  thereof,  and applications for registration of such
names and service marks.  The Executive shall assist the Company and its nominee
at all times, during the Employment Period and thereafter,  in the protection of
such information, ideas, concepts, improvements, discoveries or inventions, both
in the United States and all foreign countries,  which assistance shall include,
but  shall  not be  limited  to,  the  execution  of all  lawful  oaths  and all
assignment  documents requested by the Company or its nominee in connection with
the  preparation,  prosecution,  issuance or enforcement of any applications for
United States or foreign letters  patent,  including  divisions,  continuations,
continuations-in-part,  reissues and/or extensions thereof,  and any application
for the registration of such names and service marks.



<PAGE>


         10.3 In the event the Executive creates,  during the Employment Period,
any original work of authorship fixed in any tangible medium of expression which
is the subject matter of copyright (such as, videotapes,  written  presentations
on acquisitions,  computer programs,  drawings, maps, architectural  renditions,
models,  manuals,  brochures  or the like)  relating to the  Company's  business
products or services,  whether such work is created  solely by the  Executive or
jointly with others, the Company) shall be deemed the author of such work if the
work is prepared by the  Executive  in the scope of his  employment;  or, if the
work is not prepared by the Executive  within the scope of his employment but is
specially  ordered by the Company as a contribution  to a collective  work, as a
part of a motion  picture or other  audiovisual  work,  as a  translation,  as a
supplementary  work, as a compilation or as an instructional text, then the work
shall be  considered  to be work made for  hire,  and the  Company  shall be the
author of such work. If such work is neither  prepared by the  Executive  within
the scope of his employment nor a work specially ordered and deemed to be a work
made for hire, then the Executive  hereby agrees to sell,  transfer,  assign and
convey, and by these presents,  does sell,  transfer,  assign and convey, to the
Company all of the  Executive's  worldwide  right,  title and interest in and to
such work and all rights of copyright  therein.  The Executive  agrees to assist
the Company and its Affiliates,  at all times,  during the Employment Period and
thereafter,  in the  protection  of the  Company's  worldwide  right,  title and
interest  in and to such  work  and  all  rights  of  copyright  therein,  which
assistance  shall  include,  but shall not be limited to, the  execution  of all
documents  requested  by the  Company or its nominee  and the  execution  of all
lawful oaths and applications for registration of copyright in the United States
and foreign countries.

11.      CERTAIN REDUCTION OF PAYMENTS BY THE COMPANY.



<PAGE>


Anything in this  Agreement  to the  contrary  notwithstanding,  in the event it
shall be determined  that any payment or  distribution  by the Company to or for
the  benefit  of the  Executive  (whether  paid or  payable  or  distributed  or
distributable  pursuant  to  the  terms  of  this  Agreement  or  otherwise)  (a
"Payment") would be nondeductible by the Company for federal income tax purposes
because of Section 28OG of the Code, then the aggregate present value of amounts
payable or distributable to or for the benefit of the Executive pursuant to this
Agreement  (such  payments  or  distributions  pursuant  to this  Agreement  are
hereinafter referred to as "Agreement Payments") shall be reduced (but not below
zero) to the Reduced Amount.  The "Reduced  Amount" shall be an amount expressed
in present  value which  maximizes  the  aggregate  present  value of  Agreement
Payments  without causing any Payment to be nondeductible by the Company because
of  Section  28OG of the  Code.  Anything  in  this  Agreement  to the  contrary
notwithstanding, if the Reduced Amount is zero and it is determined further that
any  Payment  which  is  not  an  Agreement   Payment  would   nevertheless   be
nondeductible  by the Company for federal income tax purposes because of Section
28OG of the Code.  then the aggregate  present value of Payments,  which are not
Agreement  Payments,  shall  also be reduced  (but not below  zero) to an amount
expressed  in present  value which  maximizes  the  aggregate  present  value of
Payments  without causing any Payment to be nondeductible by the Company because
of Section  28OG of the Code.  For purposes of this  Section 11,  present  value
shall be  determined  in accordance  with Section  28OG(d)(4)  of the Code.  All
determinations  required  to be made under this  Section 11 shall be made by the
Company's  independent certified public accountant (the "Accounting Firm") which
shall  provide  detailed  supporting  calculations  both to the  Company and the
Executive  within  15  business  days  of the  Date  of  Termination.  Any  such
determination  by the Accounting  Firm shall be binding upon the Company and the
Executive.  The Executive  shall  determine  which and how much of the Agreement
Payments  (or,  at the  election  of the  Executive,  other  Payments)  shall be
eliminated  or  reduced  consistent  with the  requirements  of this  Section 11
provided,  that if the  Executive  does not make such  determination  within ten
business days of the receipt of the  calculations  made by the Accounting  Firm,
the Company  shall elect which and how much of the Agreement  Payments  shall be
eliminated or reduced  consistent  with the  requirements of this Section 11 and
shall notify the Executive promptly of such election.  Within five business days
thereafter,  the  Company  shall pay to or  distribute  for the  benefit  of the
Executive such amounts as are then due to the Executive under this Agreement and
shall  promptly  pay to or  distribute  for the benefit of the  Executive in the
future such amounts as become due to the Executive  under this  Agreement.  As a
result of the  uncertainty in the application of Section 28OG of the Code at the
time of the  initial  determination  by the  Accounting  Firm  hereunder,  it is
possible that Agreement Payments will have been made by the Company which should
not have been made  ("Overpayment") or that additional  Agreement Payments which
have not been made by the Company could have been made ("Underpayment"), in each
case,  consistent with the  calculations  required to be made hereunder.  In the
event that the Accounting Firm determines that an Overpayment has been made, any
such  Overpayment  shall be treated for all purposes as a loan to the  Executive
which the  Executive  shall repay to the Company,  together with interest at the
applicable  federal  rate  provided  for in  Section  7872(E)(2)  of  the  Code;
provided,  however,  that no amount  shall be  payable by the  Executive  to the
Company if and to the extent such  payment  would not reduce the amount which is
subject  to  taxation  under  Section  4999 of the Code.  In the event  that the
Accounting  Firm  determines  that  an  Underpayment  has  occurred,   any  such
Underpayment  shall be promptly paid by the Company to or for the benefit of the
Executive, together with interest at the applicable federal rate provided for in
Section 7872(f(2) of the Code.

12.      EXECUTIVE'S NON-COMPETITION OBLIGATION.

         12.1 (a) Until the Date of Termination, the Executive shall not, acting
alone or in  conjunction  with  others,  directly or  indirectly,  in any of the

engage,  directly or indirectly,  in any business which is competitive with that
of the Company or accept employment with or render services to such a competitor
as a  director,  officer,  agent,  employee  or  consultant,  or take any action
inconsistent  with the  fiduciary  relationship  of an employee to his employer;
provided, however, that the beneficial ownership by the Executive of up to three
percent  of  the  Voting-  Stock  of any  corporation  subject  to the  periodic

acting alone or in conjunction  with others,  directly or indirectly,  in any of
the  business  territories  in which the  Company  or any of its  Affiliates  is
presently or at the Date of Termination conducting,  business, invest or engage,
directly or indirectly,  in any business  which is competitive  with that of the
Company  as of the Date of  Termination  or  accept  employment  with or  render
services  to such a  competitor  as a  director,  officer,  agent,  employee  or
consultant,  or take any action inconsistent with the fiduciary  relationship of
an employee to his employer; provided, however, that the beneficial ownership by
the  Executive  of up to three  percent of the Voting  Stock of any  corporation
subject to the  periodic  reporting  requirements  of the Exchange Act shall not
violate this Section 12.2(a).

         (b) In addition to the other obligations  agreed to by the Executive in
this Agreement, the Executive agrees that if this Agreement is terminated either
by the  Company  for Cause or by the  Executive  for any reason  other than Good
Reason, then for a period of three years following, the Date of Termination,  he
shall not at any time, directly or indirectly, (i) induce, entice or solicit any
employee of the Company, to leave his employment,  (ii) contact,  communicate or
solicit any  customer or  acquisition  prospect of the Company  derived from any
customer list,  customer lead, mail, printed matter or other information secured
from the Company or its present or past  employees  or (iii) in any other manner
use any customer  lists or customer  leads,  mail,  telephone  numbers,  printed
material or other information of the Company relating thereto.


<PAGE>



         12.3 (a) If this  Agreement is  terminated  either by the Executive for
Good Reason or by the Company Without Cause,  provided that no Change in Control
of the Company has occurred  during,  the two-year period  preceding the Date of
Termination  then during the balance of the  Employment  Period or the  12-month
period commencing on the Date of Termination, whichever is longer, the Executive
shall not, acting alone or in conjunction  with others,  directly or indirectly,
in any of the business territories in which the Company or any of its Affiliates
is  presently  or at the Date of  Termination  conducting  business,  invest  or
engage,  directly or indirectly,  in any business which is competitive with that
of the Company as of the Date of Termination or accept employment with or render
services  to such a  competitor  as a  director,  officer,  agent,  employee  or
consultant,  or take any action inconsistent with the fiduciary  relationship of
an employee to his employer; provided, however, that the beneficial ownership by
the  Executive  of up to three  percent of the Voting  Stock of any  corporation
subject to the periodic  reporting,  requirements  of the Exchange Act shall not
violate this Section 12.3(a).

         (b) In addition to the other obligations  agreed to by the Executive in
this Agreement, the Executive agrees that if this Agreement is terminated either
by Executive for Good Reason or by the Company  Without Cause,  provided that no
Change in  Control  of the  Company  has  occurred  during  the two year  period
preceding  the Date of  Termination  then during the  balance of the  Employment
Period or the 12-month period  commencing on the Date of Termination,  whichever
is longer, he shall not at any time,  directly or indirectly (i) induce.  entice
or solicit any employee of the Company to leave his  employment,  (ii)  contact,

Good Reason or by the Company  Without  Cause and (b) a Chance in Control of the
Company  has  occurred  during  the  two-year  period   preceding  the  Date  of
Termination,  or if this Agreement is terminated as a result of the  Executive's
Disability,  then the  Executive  shall  not be  subject  to any  noncompetition
obligation.
