that would be excessive interest shall be applied to the reduction of the
Principal amount owing under this Convertible Note or on account of any other

interest exceeds the unpaid balance of Principal of this Convertible Note and

indebtedness of the Company to the Holder of this Convertible Note, under any
specific contingency, exceeds the highest lawful rate, the Company and the

the actual rate of interest on account of such indebtedness is uniform
throughout the term of such indebtedness, and/or (iii) allocate interest between
portions of such indebtedness, to the end that no such portion shall bear
interest at a rate greater than that permitted by law. The terms and provisions
