understands that due to the Executive's position with the Company, the Executive
will be exposed to, and has received and will receive, confidential and
proprietary information of the Company or relating to the Company's business or
affairs collectively, the "Trade Secrets"), including but not limited to
technical information, product information and formulae, processes, business and
marketing plans, strategies, customer information, other information concerning
the Company's products, promotions, development, financing, expansion plans,
business policies and practices and other forms of information considered by the
Company to be proprietary and confidential and in the nature of trade secrets.
Trade Secrets shall not include any such information which (A) was known to the
Executive prior to his employment by the Company or (B) was or becomes generally
available to the public other than as a result of a disclosure by the Executive
in violation of the provisions of this Section. Except to the extent that the
proper performance of the Executive's duties, services and responsibilities
hereunder may require disclosure, the Executive agrees that during the
Employment Term and at all times thereafter the Executive will keep such Trade
Secrets confidential and will not disclose such information, either directly or
indirectly, to any third person or entity without the prior written consent of
the Company. This confidentiality covenant has no temporal, geographical or
territorial restriction. On the Termination Date unless the Executive remains as
an employee of the Company thereafter in which case, on the date which the
Executive is no longer an employee of the Company), the Executive will promptly
supply to the Company all property, keys, notes, memoranda, writings, lists,
files, reports, customer lists, correspondence, tapes, disks, cards, surveys,
maps, logs, machines, technical data, formulae or any other tangible product or
document which has been produced by, received by or otherwise 


                                       3
<PAGE>   4
submitted to and retained by the Executive in the course of his employment with
the Company. Any material breach of the terms of this paragraph shall be
considered Cause.

      Prohibited and Competitive Activities. The Executive and the Company
recognize that due to the nature of the Executive's engagement hereunder and the
relationship of the Executive to the Company, the Executive has had and will
have access to, has had and will acquire, and has assisted and may continue to
assist in, developing confidential and proprietary information relating to the
business and operations of the Company and its affiliates, including, without
limitation, Trade Secrets. The Executive acknowledges that such information has
been and will be of central importance to the business of the Company and its
affiliates and that disclosure of it to, or its use by, others (including,
without limitation, the Executive (other than with respect to the Company's
business and affairs)) could cause substantial loss to the Company.

      The Executive and the Company also recognize that an important part of the
Executive's duties will be to develop good will for the Company and its
affiliates through the Executive's personal contact with Clients (as defined
below), employees, and others having business relationships with the Company,
and that there is a danger that this good will, a proprietary asset of the
Company, may follow the Executive if and when the Executive's relationship with
the Company is terminated. The Executive accordingly agrees as follows:

      (i) Prohibited Activities. The Executive agrees that the Executive will
not at any time during the Employment Term: (A) (other than in the course of the
Executive's employment) disclose or furnish to any other person or, directly or
indirectly, use for the Executive's own account or the account of any other
person, any Trade Secrets, no matter from where or in what manner he may have
acquired such Trade Secrets, and the Executive shall retain all such Trade
Secrets in trust for the benefit of the Company, its affiliates and the
successors and assigns of any of them, (B) directly or through one or more
intermediaries, solicit for employment or recommend to any subsequent employer
of the Executive the solicitation for employment of, any person who, at the time
of such solicitation, is employed by the Company or any affiliate, (C) directly
or indirectly, whether for the Executive's own account or for the account of any
other person, solicit, divert, or endeavor to entice away from the Company or
any entity controlled by the Company, or otherwise engage in any activity
intended to terminate, disrupt, or interfere with, the Company's or any of its
affiliates' relationships with, Clients, or otherwise adversely affect the
Company's or any of its affiliates' relationships with Clients or other business
relationships of the Company or any affiliate thereof, or (D) publish or make
any statement critical of the Company or any shareholder or affiliate of the
Company or in any way adversely affect or otherwise malign the business or
reputation of any of the foregoing persons (any activity described in clause
(A), (B), (C) or (D) of this Section being referred to as a Prohibited
Activity"); provided, however, that if in the written opinion of Counsel, the
Executive is legally compelled to disclose Trade Secrets to any tribunal or else
stand liable for contempt or suffer other similar censure or penalty, then the
disclosure to such tribunal of only those Trade Secrets which such counsel
advises in writing are legally required to be disclosed shall not constitute a
Prohibited Activity provided that the Executive shall give the Company as much
advance notice of such disclosure as is reasonably practicable. As used herein,
the term "Clients" shall mean those persons who, at any time during the
Executive's course of employment with the Company (including, without
limitation, prior to 


                                       4
<PAGE>   5
the date of this Agreement) are or were clients or customers of the Company or
any affiliate thereof or any predecessor of any of the foregoing.

      (ii) Non-Competition. By and in consideration of the Company's entering
into this Agreement, the Executive agrees that the Executive will not, during
the Employment Term and for a period of eighteen months thereafter, engage in
any Competitive Activity. The term "Competitive Activity" means engaging in any
of the following activities: (A) serving as a director of any Competitor (as
defined below), (B) directly or indirectly through one or more intermediaries,
either (X) controlling any Competitor or (Y) owning any equity or debt interests
in any Competitor (other than equity or debt interests which are publicly traded
and, at the time of any acquisition thereof by the Executive, do not in the
aggregate exceed 5% of the particular class of interests of such Competitor then
outstanding) (it being understood that, if interests in any Competitor are owned
by an investment vehicle or other entity in which the Executive owns an equity
interest, a portion of the interests in such Competitor owned by such entity
shall be attributed to the Executive, such portion determined by applying the
percentage of the equity interest in such entity owned by the Executive to the
interests in such Competitor owned by such entity), (C) employment by (including
serving as an officer, director or partner of), providing consulting services to
(including, without limitation, as an independent contractor), or managing or
operating the business or affairs of, any Competitor or (D) participating in the
ownership, management, operation or control of or being connected in any manner
with any Competitor. The term "Competitor" as used herein (i) during the
Employment Term, means any person (other than the Company, Parke Industries,
Inc. or any of their respective affiliates) that competes, either directly or
indirectly with any of the business conducted by the Company or any affiliate.

      Remedies. The Executive agrees that any breach of the terms of this
Section would result in irreparable injury and damage to the Company for which
the Company would have no adequate remedy at law. The Executive therefore agrees
that in the event of said breach or any threat of breach, the Company shall be
entitled to an immediate injunction and restraining order to prevent such breach
and/or threatened breach and/or continued breach by the Executive and/or any and
all persons and/or entities acting for and/or with the Executive, without having
to prove damages. The terms of this paragraph shall not prevent the Company from
pursuing any other available remedies to which the Company may be entitled at
law or in equity for any breach or threatened breach hereof, including but not
limited to the recovery of damages from the Executive. the provisions of this
Section 8 shall survive any termination of this Agreement. The existence of any
claim or cause of action by the Executive against the Company, whether
predicated on this Agreement or otherwise, shall not constitute a defense to the
enforcement by the Company of the covenants and agreements of this Section.

      Proprietary Information and Inventions. The Executive agrees that any and
all inventions, discoveries, improvements, processes, formulae, business
application software, patents, copyrights and trademarks made, developed,
discovered or acquired by him prior to and during the Employment Term, solely or
jointly with others or otherwise, which relate to the business of the Company,
and all knowledge possessed by the Executive relating thereto collectively, the
"Inventions"), shall be fully and promptly disclosed to the Board of Directors
and to such person or persons as the Board of Directors shall direct and the
Executive irrevocably assigns to the 



                                       5
<PAGE>   6
Company all of the Executive's right, title and interest in and to all
Inventions of the Company and all such Inventions shall be the sole and absolute
property of the Company and the Company shall be the sole and absolute owner
thereof. The Executive agrees that he will at all times keep all Inventions
secret from everyone except the Company and such persons as the Board of
Directors may from time to time direct. The Executive shall, as requested by the
Company at any time and from time to time, whether prior to or after the
expiration of the Employment Term, execute and deliver to the Company any
instruments deemed necessary by the Company to effect disclosure and assignment
of the Inventions to the Company or its designees and any patent applications
(United States or foreign) and renewals with respect thereto, including any
other instruments deemed necessary by the Company for the prosecution of patent
applications, the acquisition of letters patent and/or the acquisition of
patents or copyrights in any and all countries and to vest title thereto in the
Company or its nominee.

6.    Representations and Warranties of the Executive. The Executive represents

conflict with, and will not be constrained by, any prior or current employment,
