  2015, the Company dismissed David A. Aronson, CPA, P.A. (&ldquo;Aronson&rdquo;) as the Company&rsquo;s independent registered
  public accounting firm. The decision to dismiss Aronson was approved by the Company&rsquo;s board of directors. During the period
  of engagement from May 24<SUP>th</SUP>, 2013 to August 19<SUP>th</SUP>, 2015, the auditor&rsquo;s reports issued by Aronson did
  not contain an adverse opinion, a disclaimer of opinion, nor were the reports qualified or modified as to uncertainly, audit scope
  or accounting principles. However, the audit reports did reflect uncertainties regarding the ability of the Company to continue
  as a going concern. During the referenced period, there were no disagreements between the Company and Aronson on any matter of
  accounting principles or practices, financial statement disclosure or auditing scope or procedure which, if not resolved to the
  satisfaction of Aronson, would have caused Aronson to make reference to the matter in reports on the Company&rsquo;s financial
  statements, had any such reports been issued. During the period of engagement, there were no reportable events as that term is
