Report of Management on Internal Control over Financial Reporting as of December 31, 2011
The Company's management is responsible for establishing and maintaining adequate internal control over financial reporting
as defined in Rules 13a-15(f) and 15d-15(f) under the Securities Exchange Act of 1934. The Company's internal control system
is designed to provide reasonable assurance to our management and board of directors regarding the reliability of financial
reporting and the preparation of consolidated financial statements for external purposes in accordance with generally accepted
accounting principles. The Company's internal control over financial reporting includes those policies and procedures that
(i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions
of the assets of the Company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit
preparation of consolidated financial statements in accordance with generally accepted accounting principles, and that receipts
and expenditures of the Company are being made only in accordance with authorizations of management and directors of the
Company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or
disposition of the Company's assets that could have a material effect on the consolidated financial statements.
Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also,
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 or procedures may deteriorate.
Management assessed the effectiveness of the Company's internal control over financial reporting as of December 31, 2011. In
making this assessment, we used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway
Commission (COSO) in Internal Control - Integrated Framework. Based on our assessment and those criteria, we believe that,
as of December 31, 2011, the Company maintained effective internal control over financial reporting.
The Company's independent registered public accounting firm has audited the Company's internal control over financial
reporting as of December 31, 2011, as stated in the Report of Independent Registered Public Accounting Firm, appearing under
Item 9A, which expresses an unqualified opinion on the effectiveness of the Company's internal controls over financial
reporting as of December 31, 2011.
