     (a) is already known without restriction to the Consultant; or
     (b) is or becomes publicly known as a result of no wrongful act of the
     Consultant; or

     3.3. Non-Disclosure. The Consultant and the Consultant's representatives,
     --------------------
heirs, successors, employees, assigns, attorneys, affiliates, agents and other
representatives, as the case may be, and each of their shareholders, partners,

persons or entities acting by, through, under, or in connection with them, or
any of them, shall not, directly or indirectly, divulge, disclose, disseminate,
distribute, license, circulate, publish, use, sell or otherwise make known any
Confidential Information to any third party or person or entity not expressly
authorized by the Corporation in advance in writing to receive such Confidential
Information. The Consultant shall prevent disclosure of any Confidential
Information to any third party and shall exercise the most stringent care and
discretion in accordance with the Consultant's duty pursuant to this Agreement
to prevent any such disclosure.

     3.4. Ownership and Reproduction or Translation of Confidential Information.

decompiled, in any manner whatsoever whether electronic, electromagnetic,
electromechanical, mechanical, chemical or photographic without the prior
written consent of the Corporation.

     3.5. Removal and Return of Confidential Information. The Consultant shall
     ----------------------------------------------------
only remove such original or reproduced, replicated or photocopied Confidential
Information from the premises of the Corporation or any bailee or other place of

<PAGE>

Confidential Information upon the request of the Corporation and shall not
retain any reproductions, replications, photocopies or other copies or
renditions of any Confidential Information. The Consultant shall certify in
writing to the Corporation that the Consultant has either returned or destroyed
all such reproductions, replications, photocopies or copies or other renditions.

     3.6. Prohibition of Use. The Consultant shall not directly or indirectly
     ------------------------
make any use whatsoever of Confidential Information or of any feature,
specification, detail or other characteristic contained in, or derived from, any
Confidential Information, except as may be expressly authorized by the
Corporation in writing.

     3.7. Competitive Activities. Any unauthorized use, sale, licensing,
     ----------------------------
marketing, transfer or disclosure of Confidential Information obtained by the
Consultant, including information concerning the Confidential Information and
any future or proposed activities by the Corporation or any of the Corporation's
employees, associates, affiliates, agents, consultants or representatives, and
the fact that those activities may be considered or in production, as well as
any description of the features, specifications, or characteristics of those
activities, shall constitute unfair competition and shall be a breach of this
Agreement and of the Consultant's fiduciary duties to the Corporation. The
Consultant shall not engage in any unfair competition with the Corporation at
any time, whether during or following the completion of the term of this
Agreement.

     4. Consultations. The Consultant shall consult with the Board and the
     -----------------
officers of the Corporation, at reasonable times, concerning any issue of
importance regarding certain opportunities available to the Corporation and
other relevant matters relating to the business of the Corporation.
Specifically, subject to those restrictions specified in Paragraph 8 it is
anticipated that the Consultant shall (i) assist the officers of the Corporation
in connection with certain delegated matters regarding the fiscal requirements
of the Corporation and (ii) introduce the Corporation to investment bankers,
broker dealers, institutional investors and qualified prospective merger or
acquisition candidates for purposes of allowing the Corporation to consider and,
if appropriate, consummate and close certain mergers and acquisitions and other
opportunities. The provisions of this Agreement notwithstanding, the services of
the Consultant to be provided pursuant to the provisions of this Agreement do
not include investor relation services or the direct or indirect promotion of
the Corporation's securities in any manner whatsoever.

     5. Management Power of the Consultant. The business affairs of the
     --------------------------------------
Corporation and the operation of business of the Corporation shall be conducted
by the officers and administrative staff and employees of the Corporation. It is
the intention of the Corporation not to confer on the Consultant, and the
Consultant shall not have, any power of direction, management, supervision or
control of the administrative staff or other employees of the Corporation, or to
otherwise be involved with the management of the business of the Corporation.

     6. Authority to Contract. The Consultant shall have no power to, and the
     -------------------------

                                   Page 3 of 7
<PAGE>

Consultant shall not, obligate the Corporation in any manner whatsoever to any
contract, agreement, undertaking, commitment or other obligation.

     7. Compensation. As consideration for the services to be provided by the
     ----------------
Consultant to the Corporation pursuant to the provisions of this Agreement, on
the Effective Date the Corporation shall issue or caused to be issued to the
Consultant 3,000,000 shares of the Corporation's $.04 par value common stock,
which shares shall be "unrestricted securities" and, therefore, available for
immediate sale, transfer, or other disposition by the Consultant without
compliance with the provisions of Rule 144.

     8. Registration Status of Consultant. The Consultant is not engaged in the
     -------------------------------------
business of effecting transactions in securities for the accounts of others. The
Consultant is not registered with any agency as a broker-dealer, investment
advisor or investment manager, and, as a result, is precluded by law from
providing to the Corporation services which would be considered to be those of a
broker-dealer, investment advisor or investment manager in connection with the
placement, offer or sale of securities. In that regard, the Consultant shall not
offer, offer to sell, offer for sale, sell, or induce or attempt to induce the
purchase or sale of securities of the Corporation. None of the services to be
provided by the Consultant pursuant to the provisions of this Agreement are
intended to be or shall be construed as offering or selling securities, or
providing investment, legal or tax advice.

     9. Services of Consultant Not Exclusive. Subject to the provisions of
     ----------------------------------------
Section 3.7 of this Agreement, the Consultant may represent, perform services
for, and be employed by, any additional persons as the Consultant, in the
Consultant's sole discretion, determines to be necessary or appropriate.

     10. Legal and Equitable Remedies. Because of the uniqueness of the services
     ---------------------------------
to be performed by the Consultant for the Corporation pursuant to the provisions
of this Agreement, and because the Consultant's reputation as a business and
financial consultant may be affected by the financial success or failure or the
Corporation, in addition to the other rights and remedies that the Consultant
may have for a breach of this Agreement, the Consultant shall have the right to
enforce this Agreement, and all of its provisions, by injunction, specific
performance or other relief in a court of equity. If any legal action is
necessary to enforce or interpret any provision of this Agreement, the
prevailing party shall be entitled to reasonable attorney's fees, costs and
necessary disbursements in addition to any other relief to which that party may
be entitled.

     11. Relationship Created. The Consultant is not an employee of the
     -------------------------
Corporation for any purpose whatsoever, but is an independent contractor. The
Corporation is interested only in the results obtained by the Consultant, who
shall have the sole and exclusive control of the manner and means of performing
pursuant to this Agreement. The Corporation shall not have the right to require
the Consultant to collect accounts, investigate customer or shareholder
complaints, attend meetings, periodically report to the Corporation, follow
prescribed itineraries, keep records of business transacted, make adjustments,
conform to particular policies of the Corporation, or do anything else which

                                   Page 4 of 7
<PAGE>

would jeopardize the relationship of independent contractor between the
Corporation and the Consultant. All expenses and disbursements, including, but
not limited to, those for travel and maintenance, entertainment, office,
clerical and general administrative expenses, that may be incurred by the
Consultant in connection with this Agreement shall be borne and paid wholly and
completely by the Consultant, and the Corporation shall not be in any way
responsible or liable therefor.

     12. Indemnification. Each party shall save the other party harmless from
     --------------------
and against and shall indemnify the other party for any liability, loss, costs,
expenses, or damages however caused by reason of any injury (whether to body,
property, or personal or business character or reputation) sustained by any
person or to any person or to property by reason of any act, neglect, default,
or omission of such party or any of such party's agents, employees, or other
representatives, and, such party shall pay any and all amounts to be paid or
discharged in case of an action or any such liability less costs, expenses, or
damages. If either party is sued in any court for damages by reason of any of
the acts of the other party referred to in this paragraph, such other party
shall defend said action (or cause same to be defended) at such other party's
own expense and shall pay and discharge any judgment that may be rendered in any
such action; if such other party fails or neglects to so defend in said action,
the party sued may defend the same and any expenses, including reasonable
attorneys' fees, which such party may pay or incur in defending said action and
the amount of any judgment which such party may be required to pay as a result
of said action shall be promptly reimbursed upon demand.

     13. Governmental Rules and Regulations. The provisions of this Agreement
     ---------------------------------------
and the relationship contemplated by the provisions of this Agreement are
subject to any and all present and future orders, rules and regulations of any
duly constituted authority having jurisdiction of that relationship.

     14. Notices. All notices, requests, demands or other communications
     ------------

transmission and shall be deemed to have been duly given (i) on the date of
