&lt;p style="font: 11pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;On January 18, 2012 the Company completed the acquisition of 100% of the equity of Aviation Fuel International,
Inc., a Florida corporation (&amp;#147;AFI&amp;#148;). AFI is a purchaser and reseller of aviation fuel for commercial and private aircraft.
The consideration for the acquisition of AFI consisted of 7,400,000 shares of restricted common stock and a note payable in the
amount of $1,000,000. On June 25, 2013, the Company disaffirmed the note payable of $1,000,000. However, until the Company receives
a judicially approved release, the note payable will remain on the financial statements and is included in the balance sheet as
of June 30, 2013. Prior to the acquisition, AFI had accumulated notes payable of $1,356,300 and accounts payable of $536,610. These
liabilities have been recorded in the Condensed Consolidated Balance Sheet. These liabilities are due from AFI and were not incurred
or guaranteed by the parent company, Fuelstream, Inc.&lt;/p&gt;</NonNumbericText><FootnoteIndexer /><CurrencyCode /><CurrencySymbol /><IsIndependantCurrency>false</IsIndependantCurrency><ShowCurrencySymbol>false</ShowCurrencySymbol><DisplayDateInUSFormat>false</DisplayDateInUSFormat></Cell></Cells><ElementDataType>nonnum:textBlockItemType</ElementDataType><SimpleDataType>na</SimpleDataType><ElementDefenition>The entire disclosure for business combinations, including leverage buyout transactions (as applicable), and divestitures.
