[1] On November 3, 2014, the Company entered into an advisory service agreement with Sainuo Investment Management Ltd. (“Sainuo”) whereby Sainuo, a professional services firm based in the PRC specializing in mergers and acquisitions, business restructuring and appraisal, had been engaged to assist the Company in the identification of suitable acquisition candidates, performance of required due diligence and other business advisory services. Pursuant to the service agreement, Sainuo is entitled to a service fee (which amount is calculated based on 8% of the value of the acquisition but not to exceed RMB 3.5 million). On November 24, 2014, the Company advanced RMB3.5 million to Sainuo in accordance with the service agreement, including RMB 300,000 (US $45,122) as its advance to Sainuo for the completion of the agreed-upon advisory services, in addition to the offer of the 1.2 million shares issued to the Vessel Seller in connection with the Company’s decision to acquire Rong Zhou (see note 10), a small oil/chemical product tanker identified by Sainuo as an acquisition candidate (the “Vessel Acquisition”). Sainuo, Rong Yao International Shipping Limited, a Hong Kong company (the “Vessel Seller”) and Sino-Global executed an agreement on April 22, 2015 whereby Sainuo shall collect a service fee of RMB300,000 from the Company and remit RMB3.2 million to the Vessel Seller as Sino-Global’s partial payment of the Vessel purchase price. On December 7, 2015, the Company and the Vessel Seller entered into a supplemental agreement to terminate the proposed Vessel Acquisition. Accordingly, the advance payment of RMB 300,000 to Sainuo for advisory services was recognized as consulting service charges and reflected in the consolidated statements of operations and comprehensive income (loss) for the year ended June 30, 2016.
