        (ii) or (iii) above, respectively.

      


      16.    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. 

      


      17.  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. 

      


      18.    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.

      


      19.    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.

      


      20.    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.

      


      21.    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.
