Item 3 is hereby amended and supplemented by the addition of the following: Pursuant to a Standby Credit Facility Agreement, dated August 24, 2004, (the "Standby Credit Facility Agreement"), by and between the Company and the Fund, the Company issued to the Fund on such date a Senior Unsecured Promissory Note (the "Note") in principal amount of up to $15 million. The Company's obligations under the Standby Credit Facility Agreement and the Note have been guaranteed by the Company's subsidiaries pursuant to the Subsidiaries' Guarantee, dated August 24, 2004, in favor of the Fund (the "Subsidiaries' Guarantee"). The Company's and its subsidiaries' respective obligations under the Standby Credit Facility Agreement, the Note and the 7 Subsidiaries' Guarantee are subordinated pursuant to the Subordination Agreement, dated August 24, 2004, by and among the Company, its subsidiaries, the Fund and Textron Financial Corporation.

Tucker acquired stock options to purchase 1,100 Shares of Common Stock. The options are exercisable from May 20, 2005 to May 20, 2014. No additional securities of the Company were acquired by the Fund. The shares of Preferred Stock and Series G Preferred Stock held by the Fund are convertible 8 into shares of Common Stock. The number of shares of Common Stock into which Preferred Stock and Series G Preferred Stock may convert increases over time, as described in Amendment No. 2, due to the accrual of dividends on Preferred Stock and Series G Preferred Stock. All accrued dividends on Series G Preferred Stock that are converted into Common Stock will result in additional shares of Common Stock being issuable to holders of the Warrant and Preferred Stock as a result of the anti-dilution provisions in the Warrant and the Certificate of Designations of the Preferred Stock. As of the date hereof, based on calculations made in accordance with Rule 13-d3(d) promulgated under the Exchange Act and there being 37,488,207 shares of Common Stock outstanding (as reported on the Company's Form 10-Q for the quarter ended June 30, 2004), the number of shares of Common Stock the Fund, BBH, Long and Tucker are deemed to own and the percent of the outstanding shares of Common Stock are as follows: Shares Percentage ------ ---------- Fund 28,439,975 43.13% BBH 28,439,975 43.13% Long 28,439,975 43.13% Tucker 28,514,671 43.2% ITEM 6. CONTRACTS, ARRANGEMENTS, UNDERSTANDINGS OR RELATIONSHIPS WITH RESPECT TO THE COMMON STOCK OF THE ISSUER.
