As of October 13, 1998, Longview entered into investment advisory agreements pursuant to which it agreed to provide investment advisory services to certain individuals and entities beneficially owning all of the shares of Common Stock of the Issuer reported by Longview hereunder, including the Reporting Person Family Members and Entities. Mr. Grossman, not individually but solely as trustee of The Edward Memorial Trust, is the managing member of Longview.

The securities reported hereunder were acquired and are held by the Reporting Person Family Members and Entities as part of their investment activities. Based on recent business developments with respect to the Issuer, Longview has undertaken a review and evaluation of the investment in such securities. As part of such review and evaluation, representatives of Longview have participated, and may in the future participate, in discussions with the Issuer's management, other shareholders of the Issuer, and other relevant persons. As part of such meetings and discussions, representatives of Longview have expressed, and may in the future express, opinions on matters relating to the business, operations, assets, capital structure, dividend policy or board of directors of the Issuer, including one or more of the matters specified in Item 4(a)-(j) of Schedule 13D.

In addition, depending upon the evaluation of the business and prospects of the Issuer by Longview, market conditions and such other considerations as it may deem relevant, Longview may determine to increase, decrease, or dispose of the holdings of Common Stock of the Issuer reported hereunder, in either open market or private transactions.

Other than as described in this Item 4, none of the Reporting Persons or, to their knowledge, any other person named in Item 2 above, has any current plans or proposals which relate to or would result in any of the events or transactions described in Item 4(a)-(j) of Schedule 13D; provided that the Reporting Persons reserve the right to develop such plans or proposals.

Items 5(a), 5(b), and 5(e) are hereby amended to read as follows:

(a) - (b) (i) By virtue of its management of client accounts, including accounts held for the benefit of certain of the Reporting Persons and Reporting Person Family Entities, as of July 1, 2003, Longview may be deemed to beneficially own 7,089,853 shares of Common Stock, representing approximately 7.0% of the outstanding shares of Common Stock, calculated in accordance with Rule 13d-3 under the Exchange Act (based on 101,544,362 shares of Common Stock issued and outstanding as of March 31, as reported by the Issuer in its Quarterly Report on Form 10-Q for the quarterly period ended March 31, 2003). Longview shares the power to vote and dispose of the 7,089,853 shares of Common Stock which it may be deemed to beneficially own.

Mr. Star's wife and trusts for the benefit of Mr. Star's wife and children are a general partner or limited partner of certain partnerships which own shares of Common Stock that are managed by Longview, all of which shares are reported hereunder as being beneficially owned by Longview and Mr. Star. Mr. Star shares the power to vote and dispose of the 7,089,853 shares of Common Stock which he may be deemed to beneficially own. Mr. Star disclaims beneficial ownership of the shares of Common Stock reported hereunder.

(iii)-(v) Mr. Goodman, Mr. J. Crown, and Mr. A. Crown each beneficially own less than 5.0% of the outstanding shares of Common Stock as of July 1, 2003, calculated in accordance with Rule 13d-3 under the Exchange Act.

Crown may be deemed to beneficially own 6,980,821 shares of Common Stock on July 1, 2003, representing approximately 6.9% of the outstanding shares of Common Stock as of such date, calculated in accordance with Rule 13d-3 under the Exchange Act, by virtue of his status as co-trustee of a trust, and general partner and officer of a corporation which is a general partner of certain partnerships which own shares of Common Stock that are managed by Longview. Mr. W. Crown shares the power to vote and dispose of the 6,980,821 shares of Common Stock which he may be deemed to beneficially own. Mr. W. Crown disclaims beneficial ownership of the shares of Common Stock reported hereunder in excess of his pecuniary interest in such shares.

(vii) Mr. Grossman, not individually but solely as trustee of The Edward Memorial Trust, may be deemed to beneficially own 7,089,853 shares of Common Stock on July 1, 2003, representing approximately 7.0% of the outstanding shares of Common Stock as of such date, calculated in accordance with Rule 13d-3 under the Exchange Act, by virtue of his status as trustee of The Edward Memorial Trust, the managing member of Longview.

Mr. Grossman is also trustee of certain other trusts which may be deemed to beneficially own and share the power to vote certain of the 7,089,853 shares of Common Stock. Mr. Grossman has no pecuniary interest in any of the shares he may be deemed to beneficially own. Mr. Grossman disclaims beneficial ownership of all of the shares reported hereunder.

(e) On July 1, 2003, Mr. Goodman ceased being the President of Longview and is no longer deemed to be the beneficial owner of the shares of Common Stock which are managed by Longview but in which he has no pecuniary interest. Accordingly, Mr. Goodman is no longer deemed to be the beneficial owner of more than 5.0% of the Common Stock.

Mr. J. Crown, Mr. A. Crown, and Mr. W. Crown are officers of a corporation which is a general partner in a partnership which, on July 1, 2003, transferred certain shares of Common Stock to a trust for the benefit of Reporting Person Family Members and Entities of which Mr. W.

Crown disclaims beneficial ownership of the shares of Common Stock held by the trust, he is still deemed to be the beneficial owner of such shares.
