On August 14, 2003, the Reporting Persons distributed shares of Common Stock of the Issuer to their investors, as further described in Item 5(c). The remaining shares of Common Stock covered by this filing are being held for investment purposes, however, the Reporting Persons currently intend to engage in the orderly liquidation, over time, of their remaining investments in the Issuer subject to general market conditions and the Issuer's financial condition and performance.

Item 5. INTEREST IN SECURITIES OF THE ISSUER. (a) As of the date hereof, the Reporting Persons collectively own an aggregate of 1,360,000 shares of the Issuer's 6.25% Convertible Preferred Stock (the "Preferred Stock"), which are convertible into 1,844,068 shares of Common Stock, or approximately 0.84% of the outstanding shares of Common Stock based on 218,534,262 shares of Common Stock outstanding as of August 1, 2003 as reported by the Issuer on its quarterly report on Form 10-Q filed with the Commission on August 12, 2003.

Since none of the Reporting Persons has voting or investment power with respect to the shares of Common Stock beneficially owned by the Other Berkshire Holders, the Reporting Persons disclaim beneficial ownership of such shares. In addition, the Reporting Persons hold an aggregate of 50,113 shares of the Issuer's 12.75% Senior Exchangeable Preferred Stock, which shares are not convertible into voting securities and thus are not reported on for purposes of this Amendment No. 4 to the Schedule 13D. By virtue of the relationships described herein, the Reporting Persons may be deemed to constitute a "group" within the meaning of Rule 13d-5 under the Exchange Act. As a member of a group, each Reporting Person may be deemed to share voting and dispositive power with respect to, and therefore beneficially own, the shares beneficially owned by members of the group as a whole. The filing of this Statement shall not be construed as an admission that the Reporting Persons beneficially own those shares held by any other members of the group or the Other Berkshire Holders. The response to Item 5(b) is incorporated herein by reference. (b) Fund V holds 615,098 shares of Preferred stock, which are convertible into 834,031 shares of Common Stock. Accordingly, Fund V has sole voting power with respect to 834,031 shares of Common Stock and has sole dispositive power with respect to 834,031 shares of Common Stock. Fund V is the direct beneficial owner of the 834,031 shares of Common Stock over which it has voting and dispositive power. Based on the immediately preceding paragraph, as the sole general partner of Fund V, Fifth Berkshire may be deemed to beneficially own 834,031 shares of Common Stock held by Fund V. The filing of this Statement shall not be construed as an admission that Fifth Berkshire is, for the purpose of Section 13(d) of the Exchange Act, the beneficial owner of such shares held by Fund V. Fund VI holds 669,295 shares of Preferred Stock, which are convertible into 907,519 shares of Common Stock. Accordingly, Fund VI has sole voting power with respect to 907,519 shares of Common Stock and has sole dispositive power with respect to 907,519 shares of Common Stock. Fund VI is the direct beneficial owner of the 907,519 shares of Common Stock over which it has voting and dispositive power. Based on the immediately preceding paragraph, the sole general partner of Fund VI, Sixth Berkshire may be deemed to beneficially own 907,519 shares of Common Stock held by Fund VI.

Castle Investment is the direct beneficial owner of the 92,599 shares of Common Stock over which it has voting and dispositive power. Page 10 of 11 pages Based on the immediately preceding paragraph, Berkshire Investors, as the managing member of Castle Investment, may be deemed to beneficially own 92,599 shares of Common Stock held by Castle Investment. The filing of this Statement shall not be construed as an admission that Berkshire Investors is, for the purpose of Section 13(d) of the Exchange Act, the beneficial owners of such shares held by Castle Investment. By virtue of their positions as managing members of Fifth Berkshire, Sixth Berkshire and Berkshire Investors and managing directors of Berkshire Partners, the Berkshire Principals may be deemed to possess indirect beneficial ownership of the shares of Common Stock beneficially owned by Fund V, Fund VI, Berkshire Investors, Berkshire Partners and Castle Investment. However, none of the Berkshire Principals, acting alone, has voting or investment power with respect to the shares beneficially owned by Fund V, Fund VI, Berkshire Investors, Berkshire Partners or Castle Investment, and, as a result, each Berkshire Principal disclaims beneficial ownership of such shares of Common Stock.
