On June 5, 2019, Prager Metis CPAs, LLC (“Prager”), the Registrant’s independent registered public accounting firm, gave notice of its resignation as such, effective on that date. Matters relating to Prager’s resignation were disclosed in Registrant’s current report on Form 8-K, dated June 5, 2019.

On, June 24, 2019, the Registrant’s board of directors engaged Haskell & White LLP (“H&W”) to serve as the Registrant’s independent registered public accounting firm to audit the Registrant’s consolidated financial statements for the year ended December 31, 2018, and based on its audit, it will issue a written report on such financial statements, which are to be included in the Registrant’s Annual Report on the Form 10-K for the year ended December 31, 2018, to be filed by the Registrant under the Securities Exchange Act of 1934.

During the Registrant’s two most recent fiscal years and subsequent interim period preceding H&W’s engagement, neither the Registrant nor anyone on its behalf consulted with H&W regarding (i) the application of accounting principles to a specified transaction, either completed or proposed, or the type of audit opinion that might be rendered on the Registrant’s consolidated financial statements, and no written report or oral advice was provided by H&W to the Company as to any factor considered by the Registrant in reaching a decision as to an accounting, auditing or financial reporting issue, or (ii) any matter that was either the subject of a disagreement (as described in Item 304(a)(1)(iv) of Regulation S-K and the related instructions) or a reportable event (as described in Item 304(a)(1)(v) of Regulation S-K).
