PART II



|Item 9A. | Controls and Procedures.
|-------- | ------------------------

The Company maintains a
system of disclosure controls and procedures that is designed to provide reasonable assurance that information, which is required to be disclosed by the Company in the reports that it files or submits under the Securities and Exchange Act of 1934,
as amended, is recorded, processed, summarized and reported within the time periods specified in the rules and forms of the Securities and Exchange Commission, and is accumulated and communicated to management in a timely manner. A control system,
no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Further, the design of a control system must reflect the fact that there are resource constraints, and
the benefits of controls must be considered relative to their costs. These inherent limitations include the realities that judgments in decision-making can be faulty, and that breakdowns can occur because of simple error or mistake. Additionally,
controls can be circumvented by the individual acts of some persons, by collusion of two or more people, or by management override of the control. The design of any system of controls also is based in part upon certain assumptions about the
likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions; over time, control may become inadequate because of changes in conditions, or the degree of
compliance with the policies or procedures may deteriorate.

The Companys Chief Executive Officer and Chief Financial Officer have
evaluated this system of disclosure controls and procedures as of the end of the period covered by this Annual Report, and based on that evaluation, have concluded that the system of disclosure controls and procedures is, in fact, effective at the
reasonable assurance level. There have been no changes in our internal control over financial reporting during the most recent fiscal year that have materially affected, or are reasonably likely to materially affect, the Companys internal
control over financial reporting.
