Accountant.</B></P>

<P STYLE="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-indent: 0.5in">&nbsp;</P>

<P STYLE="font: 10pt/normal Times New Roman, Times, Serif; margin: 0">Following a competitive bidding process, on July 28, 2016,
SG Blocks, Inc. (the &ldquo;<I>Company</I>&rdquo; or &ldquo;<I>we</I>&rdquo;) dismissed its independent registered public accounting
firm, Marcum LLP (&ldquo;<I>Marcum</I>&rdquo;), and subsequently engaged Whitley Penn LLP (&ldquo;<I>Whitley Penn</I>&rdquo;).
The decision to dismiss Marcum and engage Whitley Penn was approved by the Company&rsquo;s full Board of Directors (the &ldquo;<I>Board</I>&rdquo;)
and the Audit Committee of the Board.</P>

<P STYLE="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-indent: 0.5in">&nbsp;</P>

<P STYLE="font: 10pt/normal Times New Roman, Times, Serif; margin: 0">The audit reports of Marcum on the consolidated financial
statements of the Company for each of the two most recent fiscal years ended December 31, 2015 and 2014 did not contain an adverse
opinion or a disclaimer of opinion and were not qualified or modified as to audit scope or accounting principles, however Marcum&rsquo;s
report on the Company&rsquo;s financial statements for the year ended December 31, 2015 contained a provision concerning uncertainty
as to the Company&rsquo;s ability to continue as a going concern. The financial statements did not include any adjustments that
might have resulted from the outcome of this uncertainty.</P>

<P STYLE="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-indent: 0.5in">&nbsp;</P>

<P STYLE="font: 10pt/normal Times New Roman, Times, Serif; margin: 0">During the Company&rsquo;s two most recent fiscal years ended
December 31, 2015 and 2014, and any subsequent interim period through the date of Marcum&rsquo;s dismissal, there were no: (1)
disagreements with Marcum on any matter of accounting principles or practices, financial statement disclosure, or auditing scope
or procedures, which disagreements if not resolved to Marcum&rsquo;s satisfaction, would have caused Marcum to make reference to
the subject matter of the disagreement in connection with their reports on the Company&rsquo;s consolidated financial statements,
or (2) except for the matter relating to internal control over financial reporting described below, there were no &ldquo;reportable
events,&rdquo; as defined in Item 304(a)(1)(v) of Regulation S-K (&ldquo;<I>Regulation S-K</I>&rdquo;) of the rules and regulations
of the Securities and Exchange Commission (the &ldquo;<I>SEC</I>&rdquo;), during the Company&rsquo;s years ended December 31, 2015
or 2014 or in any subsequent interim period.</P>

<P STYLE="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-indent: 0.5in">&nbsp;</P>

<P STYLE="font: 10pt/normal Times New Roman, Times, Serif; margin: 0">Marcum has communicated to the Company that we did not maintain
effective internal controls over financial reporting.&nbsp; Specifically, (i) we have experienced difficulty in generating data
in a form and format that facilitates the timely analysis of information needed to produce accurate financial reports, (ii) we
have experienced difficulty in applying complex accounting and financial reporting and disclosure rules required under GAAP and
the SEC reporting regulations, and (iii) we have limited segregation of duties.</P>

<P STYLE="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-indent: 0.5in">&nbsp;</P>

<P STYLE="font: 10pt/normal Times New Roman, Times, Serif; margin: 0">As disclosed in the Company's Annual Report on Form 10-K
for the fiscal year ended December 31, 2015, our internal controls are still in a state of transition as we work to remedy the
significant deficiencies that together constitute a material weakness in our internal control over financial reporting.</P>

<P STYLE="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-indent: 0.5in">&nbsp;</P>

<P STYLE="font: 10pt/115% Times New Roman, Times, Serif; margin: 0 0 10pt">The Company provided Marcum with a copy of the disclosures
in this report prior to filing with the SEC. Pursuant to the Company&rsquo;s request, on July 28, 2016, Marcum furnished to the
Company a letter addressed to the SEC regarding the statements contained in this report. A copy of Marcum&rsquo;s letter has been
filed as Exhibit 16.1 to this report.&nbsp;</P>

<P STYLE="font: 10pt/normal Times New Roman, Times, Serif; margin: 0">On July 29, 2016, the Audit Committee engaged Whitley Penn
LLP (&ldquo;<I>Whitley Penn</I>&rdquo;) as the Company's independent registered public accounting firm for the year ending December
31, 2016. In deciding to select Whitley Penn, the Audit Committee reviewed auditor independence issues and existing commercial
relationships with Whitley Penn and concluded that Whitley Penn has no commercial relationship with the Company which would impair
its independence for the two most recent fiscal years ended December 31, 2015 and December 31, 2014.</P>

<P STYLE="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-indent: 0.5in">&nbsp;</P>

<P STYLE="font: 10pt/normal Times New Roman, Times, Serif; margin: 0">During the Company&rsquo;s two most recent fiscal years and
the subsequent interim period preceding the engagement of Whitley Penn, neither the Company nor anyone on its behalf consulted
with Whitley Penn with respect to: (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 Company&rsquo;s consolidated financial statements, and no
written or oral advice of Whitley Penn was provided to the Company that was an important factor considered by the Company in reaching
a decision as to the accounting, auditing, or financial reporting issue; or (ii) any matter that was either the subject of a &ldquo;disagreement&rdquo;
(as defined in Item 304(a)(1)(iv) of Regulation S-K and the related instructions related thereto), or any &ldquo;reportable event&rdquo;
(as defined in Item 304(a)(1)(v) of Regulation S-K).</P>
