ITEM 4.01
        Changes in Registrant's Certifying Accountant
The
        Company's Board of Directors engaged DeCoria, Maichel & Teague, P.S., the
        independent auditor for the Company's wholly-owned subsidiary, to be its
        new
        independent auditor effective November 15, 2005, which was also the effective
        date of S.W. Hatfield, CPA's dismissal as the Company's certifying accountant by
        the Board.
Except
        for an expression of doubt about our ability to continue as a going concern,
        S.W. Hatfield
's
        audit
        reports on the Company's financial statements as of June 30, 2005 and September
        30, 2004 did not contain an adverse opinion or disclaimer of opinion, nor
        were
        they qualified or modified as to uncertainty, audit scope or accounting
        principles.
During
        the two fiscal years ended June 30, 2005 and September 30, 2004, and through
        November 15, 2005 there were no disagreements with S.W. Hatfield on any matter
        of accounting principles or practices, financial statement disclosure, or
        auditing scope or procedures, which disagreements, if not resolved to the
        satisfaction of S.W. Hatfield would have caused it to make a reference to
        the
        subject matter of the disagreements in connection with its report; and there
        were no reportable events as described in Item 304(a)(1)(iv)(B) of Regulation
        S-B promulgated by the Securities and Exchange Commission (the "SEC") pursuant
        to the Securities Exchange Act of 1934, as amended.
The
        Company provided S.W. Hatfield with a copy of this disclosure and requested
        that
        S.W. Hatfield furnish the Company with a letter addressed to the SEC stating
        whether it agrees with the foregoing statements by the Company and, if not,
        stating the respects in which it does not agree. A copy of the letter from
        S.W.
        Hatfield is filed herewith as Exhibit 16.1.
During
        the Company's two most recent fiscal years and through November 15, 2005, the
        Company did not consult DeCoria, Maichel & Teague with respect to 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 any other matters or reportable events
        listed in Item 304(a)(2) of Regulation S-B. However, IsoRay Medical, Inc.,
        the
        Company's wholly-owned subsidiary, has consulted with DeCoria, Maichel &
        Teague, its independent auditor, during these time periods solely in connection
        with IsoRay Medical's financial statements.
