     14. Governing Law. This Note is to be construed in accordance with and governed by the laws of the State of California.

     15. Amendment and Waiver. Any term of this Note may be amended only with the written consent of the Company and Holder.

     16. Notices. Except as may be otherwise provided herein, all notices, requests, waivers and other communications made pursuant to this Note shall be made in accordance with Section 5.6 of the Agreement.

     17. Severability.

     18. Assignment. The Company shall not have the right to assign its rights and obligations hereunder or any interest herein.

     19. Remedies Cumulative; Failure or Indulgence Not a Waiver. The remedies provided in this Note shall be cumulative and in addition to all other remedies available under this Note and any of the other Transaction Documents. No failure or delay on the part of Holder 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.

     20. Payments. Whenever any payment of cash is to be made by the Company to any Person pursuant to this Note, such payment shall be made in lawful money of the United States of America by a check drawn on the account of the Company and sent via overnight courier service to such Person at such address as previously provided to the Company in writing (which address, in the case of Holder as of the date of issuance hereof, shall initially be the address for Holder as set forth in the Agreement); provided that Holder may elect to receive a payment of cash via wire transfer of immediately available funds by providing the Company with prior written notice setting out such request and Holder’s wire transfer instructions.

     21. Excessive Interest. Notwithstanding any other provision herein to the contrary, this Note is hereby expressly limited so that the interest rate charged hereunder shall at no time exceed the maximum rate permitted by applicable law. If, for any circumstance whatsoever, the interest rate charged exceeds the maximum rate permitted by applicable law, the interest rate shall be reduced to the maximum rate permitted, and if Holder shall have received an amount that would cause the interest rate charged to be in excess of the maximum rate permitted, such amount that would be excessive interest shall be applied to the reduction of the principal amount owing hereunder (without charge for prepayment) and not to the payment of interest, or if such excessive interest exceeds the unpaid balance of principal, such excess shall be refunded to the Company.

     22. Waiver of Notice. To the extent permitted by law, the Company hereby waives demand, notice, protest and all other demands and notices in connection with the delivery, acceptance, performance, default or enforcement of this Note and the Transaction Documents.

     IN WITNESS WHEREOF, the Company has caused this Note to be duly executed by its officers, thereunto duly authorized as of the date first above written.
