Moran, PLLC 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 Company's financial statements or (ii)
any matter that was either the subject of a disagreement (as that term is
defined in Item 304(a)(1)(iv) of Regulation S-K) or a reportable event (as that
term is defined in Item 304(a)(1)(v) of Regulation S-K).
