Dear Sir,

As you are aware you executed  Convertible Promissory Notes to us for the total sum of FIFTY THOUSAND 00/100 DOLLARS ($50,000.00) which was to bear interest at 7% per annum and shall be due in twelve (12) months.

We believe the conversion of $50,000 of principal, and $11,252 of accrued interest should be converted into 1,020,869 common shares based on the repayment of the Loan as of today’s date.

We thank you for your co-operation and remain

Yours Truly,
