Effective September 1, 2012, Meeks International, Inc. (“MIL”), the independent registered public accounting firm of Deer Valley Corporation, a Florida corporation (the “Company”), was acquired by Thomas, Howell, Ferguson, P.A. (“THF”) in a transaction pursuant to which MIL merged its operations into THF and the professional staff and partners of MIL joined THF as employees with Charlie M. Meeks becoming a partner of THF. On September 3, 2012, MIL notified the Company of the merger and resulting resignation as the Company’s independent registered public accounting firm effective September 1, 2012. On September 6, 2012, the Board of Directors of the Company ratified and approved the engagement of THF, as the Company’s independent registered public accounting firm.

MIL audited the Company’s consolidated financial statements for the fiscal years ended December 31, 2011 and December 31, 2010. The reports of MIL on the consolidated financial statements of the Company for the fiscal years ended December 31, 2011 and December 31, 2010 did not contain an adverse opinion nor a disclaimer of opinion and were not qualified or modified as to uncertainty, audit scope or accounting principles.

In connection with MIL’s audits of the Company’s financial statements for the fiscal years ended December 31, 2011 and December 31, 2010, and through the interim period ended September 1, 2012, the Company has had no disagreement with MIL on any matter of accounting principles or practices, financial statement disclosure or auditing scope or procedure, which disagreement, if not resolved to the satisfaction of MIL, would have caused MIL to make a reference to the subject matter of the disagreements in connection with its reports on the consolidated financial statements for the fiscal years ended December 31, 2011 and December 31, 2010.

Prior to engaging THF, neither the Company nor anyone acting on the Company’s behalf consulted THF regarding either (i) the application of accounting principles to a specific completed or proposed transaction, or the type of audit opinion that might be rendered on the Company’s financial statements, and either a written report was provided to the Company or oral advice was provided that was an important factor considered by the Company in reaching a decision as to any accounting, auditing or financial reporting issues, or (ii) any matter that was either the subject of a disagreement (as defined in Item 304(a)(1)(iv) of Regulation S-K and related instructions to such item) or a reportable event (as described in Item 304 (a)(1)(v) of Regulation S-K).
