|22. | Criminal Code Compliance.In this paragraph the
      terms "interest", "criminal rate" and "credit advanced" have the meanings
      ascribed to them in Section 347 of the Criminal Code (Canada) as amended
      from time to time. The Borrower and the Lender agree that, notwithstanding
      any agreement to the contrary, no interest on the Loan or the credit
      advanced by the Lender under this Agreement will be payable in excess of
      that permitted under the laws of Canada. If the effective rate of
      interest, calculated in accordance with generally accepted actuarial
      practices and principles, would exceed the criminal rate on the credit
      advanced, then:
