money to be loaned under this Note or otherwise, exceed the maximum amount permissible under

limit of such validity, and if from any such circumstances Holder shall ever receive anything of 

value as interest or deemed interest by applicable law under this Note or any other document 

evidencing, securing or pertaining to the indebtedness evidenced by this Note or otherwise, an 

amount that would exceed the highest lawful rate, such amount that would be excessive interest 

shall be applied to the reduction of the principal amount owing under this Note or on account of 

any other indebtedness of the Company to Holder relating to this Note, and not to the payment of 

interest, or if such excessive interest exceeds the unpaid balance of principal of this Note and such 

other indebtedness, such excess shall be refunded to the Company. In determining whether or not 

the interest paid or payable with respect to any indebtedness of the Company to Holder, under any 

specific contingency, exceeds the highest lawful rate, the Company and Holder shall, to the 

maximum extent permitted by applicable law, (i) characterize any non-principal payment as an 

expense, fee or premium rather than as interest; (ii) amortize, prorate, allocate and spread the 

total amount of interest throughout the full term of such indebtedness so that 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 of this 

Section shall control and supersede every other conflicting provision of all agreements between 

the Company and Holder. The Holder has been advised by the Company to seek the advice of an 

attorney and an accountant in connection with the issuance of this Note. The Company has had the 

opportunity to seek the advice of any attorney and accountant of the Company's choice in 

connection with issuance of this Note.

which shall be deemed an original and all of which together shall constitute one instrument. 

8.10 Entire Agreement. This Note is the entire agreement between the parties hereto 

relating to the subject matter hereof and supersedes any prior arrangement or agreement, written 

or oral.
