    3.4  Governing
      Law.
      This
      Note shall be governed in all respects by the laws of the State of California
      as
      applied to agreements entered into and performed entirely within the State
      of
      California by residents thereof, without regard to any provisions thereof
      relating to conflicts of laws among different
      jurisdictions.

     

    3.5  Waiver
      and Amendment.
      Any
      term of this Note may be amended, waived or modified only with the written
      consent of Borrower and Lender.

     

    3.6  Remedies;
      Costs of Collection; Attorneys’ Fees.
      No
      delay or omission by Lender in exercising any of its rights, remedies, powers
      or
      privileges hereunder or at law or in equity and no course of dealing between
      Lender and the undersigned or any other person shall be deemed a waiver by
      Lender of any such rights, remedies, powers or privileges, even if such delay
      or
      omission is continuous or repeated, nor shall any single or partial exercise
      of
      any right, remedy, power or privilege preclude any other or further exercise
      thereof by Lender or the exercise of any other right, remedy, power or privilege
      by Lender. The rights and remedies of Lender described herein shall be
      cumulative and not restrictive of any other rights or remedies available under
      any other instrument, at law or in equity. If an Event of Default occurs,
      Borrower agrees to pay, in addition to the Loan and Interest payable thereon,
      reasonable attorneys’ fees and any other reasonable costs incurred by Lender in
      connection with its pursuit of its remedies under this Note.

     

    4.  Default
      Interest.
      Borrower does hereby agree that whenever an Event of Default exists (including
      upon the failure of Borrower to pay the Loan in full on the Maturity Date),
      Lender shall be entitled to receive and Borrower shall pay interest on the
      entire unpaid principal sum and any other amounts due Lender at a rate (the
      “Default
      Rate”)
      equal
      to the higher of (a) the highest prime rate of interest per annum published
      in
      the Money Rate Table of the Western Edition of The Wall Street Journal, as
      adjusted on a daily basis, plus twelve and one-quarter percent (12.25%) per
      annum, or (b) 20.00% per annum, in either case compounded annually. The
      Default Rate shall be computed retroactively from the Loan Closing Date until
      the date Borrower cures the Event of Default and such cure is accepted by
      Lender. This charge shall be added to the Loan, and shall be secured by the
      Security Agreement. This section, however, shall not be construed as an
      agreement or privilege to extend the date of the payment of the Loan, nor as
      a
      waiver of any other right or remedy accruing to Lender by reason of the
      occurrence of any Event of Default.

     

    5.  Savings
      Clause.
      It is
      expressly stipulated and agreed to be the intent of Borrower and Lender at
      all
      times to comply with applicable state law or applicable United States federal
      law (to the extent that United States federal law permits Lender to contract
      for, charge, take, reserve, or receive a greater amount of interest than under
      state law) and that this paragraph shall control every other covenant and
      agreement in this Note, the Loan Agreement and the Security Agreement. If the
      applicable law (state or federal) is ever judicially interpreted so as to render
      usurious any amount called for hereunder or thereunder, or contracted for,
      charged, taken, reserved, or received with respect to the Loan, or if Lender’s
      exercise of the option to accelerate the Maturity Date, or if any prepayment
      by
      Borrower results in Borrower having paid any interest in excess of that
      permitted by applicable law, then it is Lender’s express intent that all excess
      amounts theretofore collected by Lender shall be credited on the principal
      balance of this Note and all other indebtedness evidenced hereby and the
      provisions of this Note, the Loan Agreement and the Security Agreement
      immediately be deemed reformed and the amounts thereafter collectible hereunder
      and thereunder reduced, without the necessity of the execution of any new
      documents, so as to comply with the applicable law, but so as to permit the
      recovery of the fullest amount otherwise called for hereunder or thereunder.
      All
      sums paid or agreed to be paid to Lender for the use, forbearance, or detention
      of the Loan shall, to the extent permitted by applicable law, be amortized,
      prorated, allocated, and spread throughout the full stated term of the Loan
      until payment in full so that the rate or amount of interest on account of
      the
      Loan does not exceed the maximum lawful rate from time to time in effect and
      applicable to the Loan for so long as the Loan is outstanding. Notwithstanding
      anything to the contrary contained herein or in the Loan Agreement and the
      Security Agreement, it is not the intention of Lender to accelerate the maturity
      of any interest that has not accrued at the time of such acceleration or to
      collect unearned interest at the time of such acceleration.

    6.  Register.
      Borrower shall keep a register of this Note as to both principal and any
      interest. Lender may transfer this Note, but such transfer may only be effected
      by surrender of this Note to the Borrower by the transferor Lender, and by
      issuance of a new Note with identical terms (other than the Lender, which shall
      be the transferor rather than the transferor). This registration requirement
      is
      intended to qualify the Note for the portfolio interest exemption of U.S Revenue
      Code sections 87(h)(2)(B) or 881(c)(2)(B) and shall be interpreted
      accordingly.

     

    IN
      WITNESS WHEREOF, Borrower has caused this Note to be signed on the Effective
      Date.
