The Company incurred additional legal and professional fees of $72,424.

Upon the occurrence of certain significant Events of Default as specified in the Note, the Investor could have increased the outstanding balance of the Note by 20%, and upon the occurrence of certain Events of Default, the Investor could have increased the outstanding balance of the Note by 5%.
