        Management's Annual Report on Internal Control over Financial Reporting.    We are responsible for establishing and maintaining adequate internal control over financial reporting (as defined in Rule 13a-15(f) under the Exchange Act). Our internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the

preparation of financial statements for external purposes of accounting principles generally accepted in the United States.

        Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Therefore, even those systems determined to be effective can provide only reasonable assurance of achieving their control objectives.

        Our Chief Executive Officer and Chief Financial Officer, evaluated the effectiveness of our internal control over financial reporting as of December 31, 2007. 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 this evaluation, our Chief Executive Officer and Chief Financial Officer, concluded that, as of December 31, 2007, our internal control over financial reporting was effective.

Change in Internal Control Over Financial Reporting

During the course of an audit of the Company’s corporate income tax returns by the IRS, the Company determined in 2005 that certain income tax provisions and related balance sheet accounts and disclosures associated with accruals and payments of foreign income taxes had previously been inaccurately presented in the Company’s consolidated financial statements.  The errors commenced in 2001 in connection with the sale by the Company of its explosives business, including substantially all of its foreign operations, and related to the incorrect recognition of the benefit of foreign tax credits in the Company’s consolidated financial statements.  As a result, the consolidated financial statements as of December 31, 2004, and 2003, and each of the three years in the period ended December 31, 2004, and the subsequent interim fiscal periods of March 31, 2005 and June 30, 2005 were restated.

As a result, management identified a material weakness in the Company’s controls over financial reporting as of December 31, 2005 relating to the accounting for and disclosure of income taxes.  The Company continued to improve its internal controls over financial reporting related to accounting for income taxes during the first quarter of fiscal 2006, permitting it to conclude that its disclosure controls and procedures were effective as of March 31, 2006.  These additional controls include the engagement of a tax professional to perform a second review of all significant United States and foreign income tax matters and their impact on the consolidated financial statements of the Company, including appropriate footnote disclosures; the continued evaluation by the Audit Committee of the Board of Directors of the service capabilities of all accounting and tax professionals; and additional training in the treatment and accounting for income taxes for the Chief Financial Officer of the Company.  Other than as a described in the foregoing, there were no changes in the internal control over financial reporting of the Company during the quarter ended March 31, 2006 or since the date of the last evaluation that materially affect or are reasonably likely to materially affect, the Company’s internal control over financial reporting.

In light of the restatements, management has concluded that, as of June 30, 2005, a material weakness in the Company’s internal control over financial reporting existed relating to the accounting for and disclosure of income taxes, which includes the review of the treatment of the payment and accrual of foreign income taxes for accounting purposes.  The systems in place to review the tax and accounting attributes associated with the payment and accrual of foreign income taxes were insufficient to detect the errors.

The Company maintains disclosure controls and procedures designed to ensure that information required to be disclosed in its reports filed under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), is recorded, processed, summarized, and reported within the required time periods and that such information is accumulated and communicated to our management, including our chief executive officer and chief financial officer, as appropriate, to allow for timely decisions regarding required disclosure.  As required by Rule 13a-15(b) under the Exchange Act, management conducted an evaluation, under the supervision and with the participation of the chief executive officer and the chief financial officer, of the effectiveness of the design and operation of the Company’s disclosure controls and procedures as of June 30, 2005.  Based on this evaluation and as a result of material weaknesses in the internal control over
