8.             Governing Law. This Note shall be construed and enforced in accordance with, and all questions concerning the construction, validity, interpretation and performance of this Note shall be governed by, the laws of the State of New Jersey, without giving effect to provisions thereof regarding conflict of laws. Each party hereto hereby irrevocably submits to the non-exclusive jurisdiction of the state and federal courts sitting in Middlesex County in the State of New Jersey for the adjudication of any dispute hereunder or in connection herewith 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 hereto hereby irrevocably waives personal service of process and consents to process being served in any such suit, action or proceeding by sending by certified mail or overnight courier a copy thereof to such party at the address indicated in the preamble hereto 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. THE COMPANY AND THE HOLDER HEREBY IRREVOCABLY WAIVE ANY RIGHT IT MAY HAVE, AND AGREES NOT TO REQUEST, A JURY TRIAL FOR THE ADJUDICATION OF ANY DISPUTE HEREUNDER OR IN CONNECTION HEREWITH OR ARISING OUT OF THIS AGREEMENT OR ANY TRANSACTION CONTEMPLATED HEREBY.

9.             Remedies, Characterizations, Other Obligations, Breaches and Injunctive Relief. The remedies provided in this Note shall be cumulative and in addition to all other remedies available under this Note, at law or in equity

10.           Advice of Counsel. In connection with the preparation of this Note, each of the Company, its stockholders, officers, agents, and representatives acknowledges and agrees that the attorney that prepared this Note acted as legal counsel to the Holder only. Each of the Company, its stockholders, officers, agents, and representatives hereby acknowledges that (i) such party has been, and hereby is, advised to seek legal counsel and to review this Note with legal counsel of such party’s choice, and (ii) such party has sought such legal counsel, which such legal counsel has reviewed the Note, or hereby waives the right to do so. LUCOSKY BROOKMAN LLP DID NOT PROVIDE LEGAL ADVICE TO THE COMPANY IN CONNECTION WITH THIS NOTE.

11.           Usury Savings Clause. Notwithstanding any provision in this Note, the total liability for payments of interest and payments in the nature of interest, including, without limitation, all charges, fees, exactions, or other sums which may at any time be deemed to be interest, shall not exceed the limit imposed by the usury laws of the jurisdiction governing this Note or any other applicable law. In the event the total liability of payments of interest and payments in the nature of interest, including, without limitation, all charges, fees, exactions or other sums which may at any time be deemed to be interest, shall, for any reason whatsoever, result in an effective rate of interest, which for any month or other interest payment period exceeds the limit imposed by the usury laws of the jurisdiction governing this Note, all sums in excess of those lawfully collectible as interest for the period in question shall, without further agreement or notice by, between, or to any party hereto, be applied to the reduction of the outstanding principal balance of this Note immediately upon receipt of such sums by the Holder hereof, with the same force and effect as though the Company had specifically designated such excess sums to be so applied to the reduction of such outstanding principal balance and the Holder hereof had agreed to accept such sums as a penalty-free payment of principal; provided, however, that the Holder of this Note may, at any time and from time to time, elect, by notice in writing to the Company, to waive, reduce, or limit the collection of any sums in excess of those lawfully collectible as interest rather than accept such sums as a prepayment of the outstanding principal balance. It is the intention of the parties that the Company does not intend or expect to pay nor does the Holder intend or expect to charge or collect any interest under this Note greater than the highest non-usurious rate of interest which may be charged under applicable law.

12.           Specific Shall Not Limit General; Construction. No specific provision contained in this Note shall limit or modify any more general provision contained herein. This Note shall be deemed to be jointly drafted by the Company and the Holder and shall not be construed against any person as the drafter hereof.

13.           Failure or Indulgence Not Waiver. No failure or delay on the part of this Note in the exercise of any power, right or privilege hereunder shall operate as a waiver thereof, nor shall any single or partial exercise of any such power, right or privilege preclude other or further exercise thereof or of any other right, power or privilege.

14.           Notice. Notice shall be given to each party at the address indicated in the preamble hereto or at such other address as provided to the other party in writing.
