The Existing Note, together with this Amendment shall collectively be referred to as the "Note."

NOW THEREFORE, in consideration of the foregoing recitals and the mutual covenants, representations, warranties, conditions, and agreements hereinafter expressed, the Borrower and the Holder hereby agree as follows:

1.Defined Terms. All capitalized terms used in this Amendment and not otherwise defined shall have the meanings given to such terms in the Existing Note.

2.Additional Principal; Amendments.

a.Additional Principal. Holder hereby agrees to loan to Borrower an additional $12,223, thereby increasing the face amount of the Note to $132,223 (the "Additional Principal"); provided, however, that the Additional Principal carries an original issue discount of $1,223 to cover the Holder's monitoring costs associated with the Existing Note and the Additional Principal, which is included in the Additional Principal balance, and which such amount of original issue discount will not be disbursed to Borrower.

b.Amendments. Any reference made in the Existing Note or in any Transaction Document to the "Principal" is hereby deemed to mean "the sum of US$132,223.00."

3.Disbursements. $1,000 of the Additional Principal shall be withheld and not disbursed to the Borrower and instead paid to the Holder's legal counsel for fees and expenses incurred in connection with this Amendment. Thus, the amount actually advanced by Holder to Borrower pursuant to this Amendment following subtraction of such expense amount and the original issue discount as described in Section 2(a) shall be $10,000.
