Item 4.01 Changes in Registrant's Certifying Accountant.

         On March 6, 2006, our audit committee dismissed Raich Ende Malter & Co.
LLP ("Raich Ende") as our independent public accountant and selected Kevane Soto
Pasarell Grant Thornton LLP ("Kevane") to serve as our independent public
accountant for the year ending October 31, 2006. At no time since its engagement
has Kevane had any direct or indirect financial interest in or any connection
with us or any of our subsidiaries other than as independent accountant.

         Our financial statements at June 30, 2005 and for the year then ended
and at June 30, 2004 and the period from January 14, 2004 (inception) to June
30, 2004 were audited by Raich Ende. The audit report of Raich Ende did not
contain an adverse opinion or disclaimer of opinion and was not modified as to
uncertainty, audit scope or accounting principles. There were no disagreements
with Raich Ende during the period ended June 30, 2005 or during the period
subsequent to June 30, 2005 on any matter of accounting principles or practices,
financial statement disclosure or auditing scope or procedure.

         Kevane served as the independent accountant for our subsidiary, Plaza
Consulting Group, Inc. ("Plaza"), for October 31, 2005 and the two years in the
period then ending. Plaza consulted Kevane in connection with the Form 8-K,
including the pro forma financial statements included therein, relating to the
reverse acquisition.
