Each comment point in your letter will be addressed below and in an amended Form 10-SB, and an amended Form 10-QSB to be filed on EDGAR: 1. We have revised our calculations for the conversion option using the Black-Scholes option pricing model using the following assumptions: stock price volatility of 242%; risk free interest rate of 3.5%; dividend yield of 0% and 3 year term which resulted in an embedded derivative liability of $120,762. Additionally we have revised our disclosure regarding the methodology of valuing the conversion option of the debt. We have revised our stock price volatility related to the Black- Scholes options pricing model for the warrants to 242%. The stock price volatility of 242% was determined based upon 6 similar publicly traded companies. As a result, the fair value of the warrants totaled $77,389. We have revised our allocation of the principal balance of the convertible debt resulting in $120,762 allocated towards the derivative liability and $77,389 towards the warrant liability. Please see the attached pages, which provide the substantiation for the above-mentioned changes. 2. As requested, the Company will comply with Item 308(c) in future filings. The Company confirms that there were no changes in internal controls over financial reporting that occurred during the last quarter that has reasonably affected, or is reasonably likely to materially affect, internal controls over financial reporting.
