18.  Remedies, Other Obligations, Breaches and Injunctive Relief. The Lender’s
remedies provided in this Note shall be cumulative and in addition to all other
remedies available to the Lender under this Note, at law or in equity (including
a decree of specific performance and/or other injunctive relief), no remedy of
the Lender contained herein shall be deemed a waiver of compliance with the
provisions giving rise to such remedy and nothing herein shall limit the
Lender’s right to pursue actual damages for any failure by the Company to comply
with the terms of this Note. No remedy conferred under this Note upon the Lender
is intended to be exclusive of any other remedy available to the Lender,
pursuant to the terms of this Note or otherwise. No single or partial exercise
by the Lender of any right, power or remedy hereunder shall preclude any other
or further exercise thereof. The failure of the Lender to exercise any right or
remedy under this Note or otherwise, or delay in exercising such right or
remedy, shall not operate as a waiver thereof. Every right and remedy of the
Lender under any document executed in connection with this transaction may be
exercised from time to time and as often as may be deemed expedient by the
Lender. The Company acknowledges that a breach by it of its obligations
hereunder will cause irreparable harm to the Lender and that the remedy at law
for any such breach may be inadequate. The Company therefore agrees that, in the
event of any such breach or threatened breach, the Lender shall be entitled, in
addition to all other available remedies, to an injunction restraining any
breach, and specific performance without the necessity of showing economic loss
and without any bond or other security being required.

19.  Governing Law; Jurisdiction. All questions concerning the construction,
validity, enforcement and interpretation of this Agreement shall be governed by
the internal laws of the State of New Jersey, without giving effect to any
choice of law or conflict of law provision or rule (whether of the State of New
Jersey or any other jurisdictions) that would cause the application of the laws
of any jurisdictions other than the State of New Jersey. Each party hereby
irrevocably submits to the exclusive jurisdiction of the Superior Court of the
State of New Jersey sitting in Hudson County, New Jersey and the United States
Federal District Court for the District of New Jersey sitting in Newark, New
Jersey, for the adjudication of any dispute hereunder or in connection herewith
or therewith, or with any transaction contemplated hereby or discussed herein,
and hereby irrevocably waives, and agrees not to assert in any suit, action or
proceeding, any claim that it is not personally subject to the jurisdiction of
any such court, that such suit, action or proceeding is brought in an
inconvenient forum or that the venue of such suit, action or proceeding is
improper. Each party hereby irrevocably waives personal service of process and
consents to process being served in any such suit, action or proceeding by
mailing a copy thereof to such party at the address for such notices to it under
this Agreement and agrees that such service shall constitute good and sufficient
service of process and notice thereof. Nothing contained herein shall be deemed
to limit in any way any right to serve process in any manner permitted by law.

20.  No Inconsistent Agreements. None of the parties hereto will hereafter enter
into any agreement, which is inconsistent with the rights granted to the parties
in this Note.

21.  Third Parties. Nothing herein expressed or implied is intended or shall be
construed to confer upon or give to any person or entity, other than the parties
to this Note and their respective permitted successor and assigns, any rights or
remedies under or by reason of this Note.

22.  Waiver of Jury Trial. AS A MATERIAL INDUCEMENT FOR THE LENDER TO LOAN TO
THE COMPANY THE MONIES HEREUNDER, THE COMPANY HEREBY WAIVES ANY RIGHT TO TRIAL
BY JURY IN ANY LEGAL PROCEEDING RELATED IN ANY WAY TO THIS AGREEMENT AND/OR ANY
AND ALL OF THE OTHER DOCUMENTS ASSOCIATED WITH THIS TRANSACTION.

23.  Entire Agreement.  This Note (including any recitals hereto) set forth the
entire understanding of the parties with respect to the subject matter hereof,
and shall not be modified or affected by any offer, proposal, statement or
representation, oral or written, made by or for any party in connection with the
negotiation of the terms hereof, and may be modified only by instruments signed
by all of the parties hereto.
