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.

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. 25. 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. 26. 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. 27.
