on, place in trust (voting or otherwise), transfer by operation of law, grant a
proxy with respect to or in any other way encumber or dispose of, directly or

Agreement and prior to any such Transfer, the transferee of such Restricted
Shares (each, a "Transferee") shall execute an instrument satisfactory to the
Company and Mr. DiMino agreeing to be bound by all of the terms and provisions

                                   ARTICLE II
                           EFFECTIVENESS; TERMINATION

         Section 2.1. Effectiveness; Termination of Agreement. This Agreement
shall become effective as of the Effective Date and shall terminate (i) with
respect to those Shareholders hereto other than Fifth Avenue Capital Partners,
as set forth in Section 1.1.(a), or (ii) upon the written consent of the Company
and Andre' DiMino; provided, however, that no such termination shall relieve any
person or entity of any liability for a breach or default of this Agreement
prior to the date of such termination.


                                   ARTICLE IV
                                  MISCELLANEOUS

         Section 3.1. Recapitalization, Exchanges, etc. Affecting the Common
Stock. The provisions of this Agreement shall apply to the full extent set forth
herein with respect to (a) the Restricted Shares and (b) any and all shares of
capital stock of the Company or any successor or assign of the Company (whether
by merger, consolidation, sale of assets or otherwise) which may be issued in
respect of, in exchange for, or in substitution for the Restricted Shares, by
reason of any stock dividend, split, reverse split, combination,
recapitalization, reclassification, merger, consolidation or otherwise. In the
event of any change in the capitalization of the Company, as a result of any
stock split, stock dividend or stock combination, the provisions of this
Agreement shall be appropriately adjusted.

         Section 3.2. No Joint Venture or Partnership. No party hereto shall
have any authority to bind or commit any other party hereto and no such
authority shall be implied by the provisions hereof. Nothing herein shall be
deemed or construed to create a joint venture, partnership or agency
relationship between any of the parties hereto for any purpose.

         Section 3.3. Injunctive Relief. Each of the parties hereto acknowledges
that it would be impossible to determine the amount of damages that would result
from any breach of any of the provisions of this Agreement and that the remedy
at law for any breach, or threatened breach, of any of such provisions would
likely be inadequate and, accordingly, each other party shall, in addition to
any other rights or remedies which it may have, be entitled to seek such
equitable and injunctive relief as may be available from any court of competent
jurisdiction to compel specific performance of, or restrain any party from
violating, any of such provisions. In connection with any action or proceeding
for injunctive relief, each of the parties hereto hereby waives the claim or
defense that a remedy at law alone is adequate and, to the maximum extent
permitted by law, consents to have each provision of this Agreement specifically
enforced against him or her, without the necessity of posting bond or other
security against him or her, and consents to the entry of injunctive relief
against him or her enjoining or restraining any breach or threatened breach of
such provisions of this Agreement.

         Section 3.4. Successors and Assigns. This Agreement shall be binding
upon and inure to the benefit of the parties hereto and their respective
successors, assigns and legal representatives. This Agreement shall be for the
sole benefit of the parties to this Agreement and their respective successors,
permitted assigns and legal representatives and is not intended, nor shall be
construed, to give any person or entity, other than the parties hereto and their
respective successors, permitted assigns and legal representatives, any legal or
equitable right, remedy or claim hereunder. This Agreement may not be assigned
by operation of law or otherwise, and any attempted assignment shall be null and
void, except that any Shareholder may assign his or her rights hereunder, in
whole but not in part, in connection with a Transfer of Restricted Shares made
in strict compliance with all of the provisions of this Agreement, including,
without limitation Section 1.2 of this Agreement.

<PAGE>

         Section 3.5. Expenses. Each of the parties hereto shall pay its own
expenses incident to this Agreement and the transactions contemplated hereby.

         Section 3.6. Amendment; Waiver.

         (a) This Agreement may be amended only by a written instrument duly
executed by (i) the Company, (ii) Mr. DiMino and (iii) Shareholders holding more
than 85% of the outstanding Restricted Shares.

         (b) No failure by any party to insist upon the strict performance of
any covenant, duty, agreement or condition of this Agreement or to exercise any
right or remedy consequent upon breach thereof shall constitute a waiver of any
such breach or of any other covenant, duty, agreement or condition, any such
waiver being effective only if contained in a writing executed by the waiving
party.

         Section 3.7. Notices. Except as otherwise provided in this Agreement,
all notices, requests, claims, demands, waivers and other communications
hereunder shall be in writing and shall be deemed to have been duly given when
delivered by hand, when delivered personally or by courier, three days after
being deposited in the mail (registered or certified mail, postage prepaid,
return receipt requested), or when received by facsimile transmission if
promptly confirmed by one of the foregoing means, as follows: if to the Company
at 224-S Pegasus Avenue, Northvale, NJ 07647, and if to the other parties at the
address or facsimile transmission number specified below his or her name on the
signature pages hereto (or, in the case of persons or entities who become
parties hereto subsequently, at their last addresses or facsimile transmission
numbers shown on the record books of the Company). Each Shareholder, by notice
given to the Company in accordance with this Section 3.7, may change the address
or facsimile transmission number to which such notice or other communications
are to be sent to such Shareholder. Whenever pursuant to this Agreement any
notice is required to be given by any Shareholder to any other Shareholder or
Shareholders, such Shareholder may request from the Company a list of addresses
and facsimile transmission numbers of all Shareholders of the Company, which
list shall be promptly furnished to such Shareholder.

         Section 3.8. Applicable Law. This Agreement shall be governed, and
construed in accordance with, the internal laws of the State of New Jersey,
without reference to the choice of law principles thereof.

         Section 3.9. Headings. The descriptive headings of the several sections
in this Agreement are for convenience only and do not constitute part of this
Agreement and shall not affect in any way the meaning or interpretation of this
Agreement.

         Section 3.10. Integration. This Agreement and the other writings
referred to herein or delivered pursuant hereto which form a part hereof contain
the entire understanding of the parties with respect to its subject matter. This
Agreement supersedes all prior agreements and understandings between the parties
with respect to its subject matter. There are no restrictions, agreements,
promises, representations, warranties, covenants or undertakings with respect to
its subject matter other than those expressly set forth or referred to herein.

<PAGE>

         Section 3.11. Severability. If any term or provision of this Agreement
or any application thereof shall be declared or held invalid, illegal or
unenforceable, in whole or in part, whether generally or in any particular
jurisdiction, such provision shall be deemed amended to the extent, but only to
the extent, necessary to cure such invalidity, illegality or unenforceability,
and the validity, legality and enforceability of the remaining provisions, both
generally and in every other jurisdiction, shall not in any way be affected or
impaired thereby.

         Section 3.12. Consent to Jurisdiction. Each of the parties hereto
hereby (i) irrevocably consents and submits to the sole exclusive jurisdiction
of the United States District Court for the District of New Jersey or the
Superior Court of New Jersey (and of the appropriate appellate courts therefrom)
in connection with any suit, action or other proceeding arising out of or
relating to this Agreement, (ii) irrevocably waives, to the fullest extent
permitted by law, any objection that it may now or hereafter have to the laying
of the venue of any such suit, action or proceeding in any such court or that
any such suit, action or proceeding which is brought in any such court has been
brought in an inconvenient forum, and (iii) agrees that service of any summons,
complaint, notice or other process relating to such suit, action or other
proceeding may be effected in the manner provided by Section 3.7 of this
Agreement.

         Section 3.13. Counterparts. This Agreement may be executed in
counterparts, each of which shall be deemed an original, but all of which shall
together constitute one and the same instrument.
