which have been designed to permit us to effectively identify and timely disclose important information. Our management, including our Chief Executive
Officer and Chief Financial Officer, concluded that the controls and procedures were effective as of December 31, 2006 to ensure that material information
was accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely
decisions regarding required disclosure.
Changes In Internal Control
During the three months ended December 31, 2006, we did not make any changes in our internal control over financial reporting that have materially
affected, or are reasonably likely to materially affect, our internal control over financial reporting.
Management’s Annual Report on Internal Control Over Financial Reporting
Management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Rules 13a-15(f)
and 15d-15(f) under the Securities Exchange Act of 1934. Our internal control over financial reporting is designed to provide reasonable assurance regarding
the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with accounting principles generally
accepted in the United States of America.
Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Projections of any evaluation of
effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance
with the policies may deteriorate.
