ITEM 5.05.          Amendment to the Registrant's Code of Ethics

On November 1, 2004, the Company adopted a revised edition of its Standards of Ethics and Business Conduct ("Standards"), which is a "code of ethics" consistent with Item 406(b) of Regulation S-K. The revised Standards, among other changes, includes a separate section captioned "Financial Code of Ethics for the Chief Executive Officer, the President, the Chief Financial Officer and Other Employees with Financial Reporting Responsibilities," that requires certain of our employees to adhere to additional standards of ethics and conduct, consistent with the requirements and regulations of the Securities Exchange Commission. This separate section was added to consolidate the standards applicable to those employees that were contained in disparate sections of the prior version of the Standards, as well as in other Company policies.

A copy of the revised Standards is attached as Exhibit 14 to this Report on Form 8-K.
