&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"&gt;&amp;#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;On January 30, 2013, the Company entered into
an agreement with Asher Enterprises, a Delaware corporation, an accredited investor, whereby Asher Enterprises loaned the Company
the aggregate principal amount of $53,000, less $3,000 for legal related costs, together with interest at the rate of eight percent
(8%) per annum, until the maturity date of November 1, 2013. The original issue discount note, as described in ASC 480-55, may
not be prepaid in whole or in part.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"&gt;&amp;#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;If the Note is not paid in full with interest
on the maturity date, Asher has the right to convert this Note into restricted common shares of the Company. The Company at its
option may elect to convert all or part of the principal and any accrued unpaid interest on these notes at any time or times on
or before the maturity based on a conversion price. The conversion price (subject to equitable adjustments for stock splits, stock
dividends or rights offerings by the Borrower) shall equal to 55% multiplied by the average of the two lowest closing prices during
the fifteen (15) trading days prior to conversion notice.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"&gt;&amp;#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The conversion feature within this note has
been determined to be an embedded derivative liability requiring bifurcation and was valued using Black Scholes at $67,256. The
Company also recognized a&amp;#160;loss on Derivative Valuation of $143,689 for the year ended May 31, 2013.&lt;/p&gt;
