Explanatory Note

This amendment is being filed to complete our disclosure requirement with respect to Item 9A Controls and Procedures in our original filing of Form 10-K for the year ended December 31, 2004.  Specifically, we are clarifying our previous disclosure to state the fact that the two material weaknesses were effectively remediated with minor enhancements to internal controls in the quarter ended December 31, 2003.  Although this matter relates to the quarter ended December 31, 2003, this amendment is being made to our original filing on Form 10-K for the year ended December 31, 2004.  

The previous Item 9A disclosure is repeated in its entirety and additional paragraphs under the heading Quarter Ended December 31, 2003 disclose the fact these material weaknesses were remediated with minor enhancements to internal controls in the quarter ended December 31, 2003.  This improvement to our disclosure regarding controls and procedures did not affect previously reported results of operations, financial position, shareholders’ equity or cash flows.  Also, no other information in the original filing is being revised.  

PART II

ITEM 9A.  Controls and Procedures

Conclusion Regarding the Effectiveness of Disclosure Controls and Procedures

As of the end of the period covered by this report, we carried out an evaluation, under the supervision and with the participation of the Chief Executive Officer and Chief Financial Officer, of the design and operation of our disclosure controls and procedures, as defined in Rules 13a-15(e) and 15d-15(e) of the Securities and Exchange Act of 1934. This evaluation was conducted to determine whether the disclosure controls and procedures were effective and timely in bringing material information to the attention of senior management and are designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of our financial statements in accordance with generally accepted accounting principles.  Based on that evaluation, the Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures are effective in ensuring material information required to be disclosed in reports filed under the Act is recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission's rules and forms and is accumulated and communicated to our Chief Executive Officer and Chief Financial Officer to allow timely decisions regarding required disclosure.

Changes in Internal Control Over Financial Reporting

Our disclosure controls and procedures and internal controls over financial reporting are routinely evaluated and tested for effectiveness.  These evaluations are discussed with management and the Audit Committee.  As a result of these evaluations, revisions and corrective actions are made to ensure the continuing effectiveness of our disclosure controls and procedures and internal controls over financial reporting.

There were no changes in the design or operation of our internal controls over financial reporting that occurred during the year ended December 31, 2004 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Quarter Ended December 31, 2003

The following circumstances relate to our disclosure for the year ended December 31, 2003.  As we previously reported on Form 10-K for the year ended December 31, 2003, as part of the

2

audit of the financial statements for the year ended December 31, 2003, our independent auditors communicated to management and the Audit Committee two conditions of material weakness:  1.)  loss data for claims and 2.)  routine assessment for potential impairment of intangible assets and goodwill.  Because there were no failures in the accuracy, completeness and existence of the loss data for claims and there were no failures in the routine inquiry for impairment and the related internal controls were promptly enhanced during the fourth quarter of 2003, our principal executive officer and principal financial officer concluded that our disclosure controls and procedures were effective as of December 31, 2003.  

These material weaknesses do not still exist.  These material weaknesses were remediated with minor enhancements to internal controls in the quarter ended December 31, 2003.  These minor enhancements have not materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.  Accordingly, we concluded and disclosed that our disclosure controls and procedures were effective for the quarter ended December 31, 2003 in our Form 10-K.  

We evaluated and concluded our disclosure controls and procedures were effective for every period since December 31, 2003.  Additionally, our assessment of the effectiveness of our internal control over financial reporting as of December 31, 2004 has been audited by KPMG LLP, an independent registered public accounting firm.  Their report expresses an unqualified opinion on our assessment of the effectiveness of our internal control over financial reporting as of December 31, 2004 and is included in Item 8 under the heading Report of Independent Registered Public Accounting Firm.

Management's Report on Internal Control Over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Exchange Act Rule 13a-15(f) and 15(d)-15(f).  Under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, we conducted an evaluation of the effectiveness of our internal control over financial reporting based on the framework in Internal Control - Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission.  Our evaluation of internal control over financial reporting did not include the internal control of our 30.6% controlling interest in A-1 Building Components, LLC which was acquired in September 2004.  Assets of $9.3 million and building product sales of $7.1 million for this operation were included in our consolidated financial statements as of and for the year ended December 31, 2004.  Based on our evaluation under the framework in Internal Control - Integrated Framework, our management concluded that our internal control over financial reporting was effective as of December 31, 2004.

Our assessment of the effectiveness of our internal control over financial reporting as of December 31, 2004 has been audited by KPMG LLP, an independent registered public accounting firm.  Their report expresses an unqualified opinion on our assessment of the effectiveness of our internal control over financial reporting as of December 31, 2004 and is included in Item 8 under the heading Report of Independent Registered Public Accounting Firm.
