Item 5. Other Events.

As announced on March 11, 2003, King received a letter from the SEC with respect to an SEC investigation of King. The letter was accompanied by a subpoena requesting the production of documents. In light of the SEC investigation and as recommended by King’s management, the audit committee of King’s Board of Directors initiated its own related internal review and retained independent counsel, who retained an independent accounting firm, to assist the audit committee. On March 31, 2003, because the audit committee’s investigation was not complete and no conclusions had been reached, King filed a Form 12b-25 with the SEC to obtain a 15-day extension for filing its Form 10-K in order to provide the audit committee and its independent legal counsel with additional time to conduct a more thorough review. That review is continuing.

The financial statements included in this filing are the unaudited financial statements of the Company for the year ended December 31, 2002. There can be no assurance that the audited consolidated financial statements, once issued, will not contain material changes from the unaudited consolidated financial statements filed herewith.

The information filed herewith does not include the report of PricewaterhouseCoopers, the Company’s independent auditor, as the financial statements filed are unaudited consolidated financial statements. Additionally, the information filed herewith does not contain disclosure on controls and procedures, the Sections 302 and 906 certifications currently required to be included in report on Form 10-K or any accompanying exhibits.

Item 7. Financial Statements, Pro Forma Financial Information and Exhibits.

     (c)  Exhibits. Exhibits required by Item 601 of Regulation S-K are incorporated herein by reference and are listed on the attached Exhibit Index of this Current Report on Form 8-K.
