its engagement, any trade secrets or other information reasonably deemed or
designated as confidential by the Company which are acquired by the Consultant
in the course of performing its services. (A trade secret is information not
generally known to the trade which gives the Company an advantage over its
competitors. Trade secrets can include, by way of example, products or services
under development, production methods and processes, sources of supply, customer
lists, marketing plans, and information concerning the filing or pendency of
patent applications.) Any financial advice rendered by the Consultant pursuant
to its engagement, may not be disclosed publicly in any manner without the prior
written approval of the Company. At the conclusion of its engagement, the
Consultant shall return all material deemed confidential, supplied by the
Company.

6. Status of Consultant: The Consultant shall be deemed to be an independent
contractor, and, except as expressly provided or authorized in this Agreement,
shall have no authority to act for or represent the Company. The Consultant
shall have no authority to bind the Company to any contract or other legal
obligation, whether written, oral or implied.

7. Other Activities of Consultant: The Company recognizes that the Consultant
now renders and may continue to render financial consulting and other investment
banking services to other companies which

                                       3

may or may not conduct business and activities similar to those of the Company.
The Company and Consultant shall schedule periodic meetings at the Company's
offices in Clifton, New Jersey at intervals to be established to review and
consult.

8. Control: Nothing contained herein shall be deemed to require the Company to
take any action contrary to its Certificate of Incorporation, as amended, or
By-Laws, as amended, or any applicable statute or regulation, or to deprive its
Board of Directors of their responsibility for overseeing the business and
affairs of the Company.

9. Notice: Any notices hereunder shall be sent to the Company and the Consultant
at their respective addresses as set forth above. Any notice shall be given by
registered or certified mail, postage prepaid, and shall be deemed to have been
given when deposited in the United States mail. Either party may designate any
other address to which notice shall be given, by giving written notice to the
other of such change of address in the manner herein provided.

10. Governing Law: This Agreement has been made in the State of New York and
shall be construed and governed in accordance with the laws thereof without
regard to conflicts of laws.

11. Arbitration of Disputes: Any controversy or claim arising out of or relating
to this Agreement or the breach thereof, shall be settled by arbitration in the
City of New York in accordance with the then existing expedited rules of the
American Arbitration Association (three arbitrators), and judgment upon the
award rendered may be entered in any court having jurisdiction thereof. The
parties shall split equally the costs of arbitration unless the arbitrators
order otherwise, or unless the parties agree to allocate the costs differently.
The parties agree that the award of the arbitrators shall be final and binding.

12. Entire Agreement: This Agreement contains the entire agreement between the
parties and may not be altered or modified, except by means of a writing signed
by each of the parties hereto. Any and all previous or contemporaneous
agreements, understandings, representations and statements, oral or written,
between the parties relating to consulting and/or advisory services are hereby
superceded and shall be of no further force or effect.

13. Binding Effect: Assignment: This Agreement shall be binding upon the parties
hereto and their respective heirs, administrators, successors, and assigns.
Notwithstanding the foregoing, the Consultant may not assign this Agreement and
may not assign or subcontract the performance of its services hereunder.

14. Counterparts: This Agreement may be executed in counterparts, each of which
shall be deemed to be an original as against any party whose signature appears
thereon, and all of which shall together constitute one and the same agreement.
This Agreement shall become binding when one or more counterparts hereof,
individually or taken together, shall bear the signatures of all of the parties
reflected hereon as the signatories.

15. Severability: If any provision of this Agreement for any reason shall be
held to be illegal, invalid or unenforceable, such provision shall not effect
any other provision of this Agreement, and this Agreement shall be construed as
if such illegal, invalid or unenforceable provision had never been included
herein.

16. Limitation of Liability: In the event the Consultant fails to perform, is
unable to perform or is prevented from performing its duties under this
Agreement, the Consultant's entire liability shall not exceed the amount of
compensation the Consultant has received from the Company.

17. Drafting: Each party acknowledges that its legal counsel participated in the
preparation of this Agreement and, therefore, stipulates that the rule of
construction that ambiguities are to be resolved against the drafting party
shall not be applied in the interpretation of this Agreement to favor any party
against the other.
