EXPLANATORY NOTE

As previously reported in a Current Report on Form 8-K filed on February 4, 2016 (“Original Form 8-K”), on January 29, 2016 Magnolia Solar Corporation, a Nevada corporation (the “ Company”), entered into an Agreement and Plan of Merger (the “Merger Agreement”) with Ecoark, Inc., a Delaware corporation (“Ecoark”), and Magnolia Solar Acquisition Corporation, a Delaware corporation and a wholly-owned subsidiary of the Company (the “Merger Sub”), providing for the merger of Merger Sub with and into Ecoark (the “Merger”), with Ecoark surviving the Merger as a wholly-owned subsidiary of the Company. The Original Form 8-K was amended by a Current Report on Form 8-K, filed on May 10, 2016 (“Amendment #2”) which filed the required financial statements and pro forma financial information.

Prior to the completion of the Merger on March 24, 2016, in a special shareholder meeting on March 18, 2016, the following actions to amend the Articles of Incorporation were undertaken by Ecoark Holdings to:

1. effect a change in the name of our company from Magnolia Solar Corporation to Ecoark Holdings Inc.;

2. effect a reverse stock split of our common stock by a ratio of one-for-two hundred fifty shares (1 for 250);

3. effect an increase in the number of our authorized shares of common stock, par value $0.001 per share, to 100,000,000; and

4. effect the creation of 5,000,000 shares of “blank check” preferred stock.

With this Current Report on Form 8-K (“Amendment #3”), we are filing the Consent of Independent Registered Public Accounting Firm, with respect to the consolidated balance sheets of EcoArk, Inc. and Subsidiaries (the “Company”) as of December 31, 2015 and 2014 and the related consolidated statements of operations, changes in stockholders’ equity (deficit), and cash flows for the years then ended, which were filed with the Securities and Exchange Commission on May 10, 2016 with Amendment No. 2.

* Filed herewith.
