Item 4.  Purpose of Transaction.
         ----------------------

Item 4 is hereby amended and restated in its entirety as follows:

     The Reporting Persons have acquired the Shares reported herein for
investment purposes. Consistent with such purpose, the Reporting Persons have
had, and may have in the future, discussions with management of the Issuer and
may make suggestions concerning the Issuer's operations, prospects, business and
financial strategies, assets and liabilities, business and financing
alternatives and such other matters as the Reporting Persons may deem relevant
to their investments in the Shares. Each Reporting Person expects that it will,
from time to time, review its investment position in the Issuer and may,
depending on market and other conditions, increase or decrease its investment
position.

     Whether the Reporting Persons purchase any additional Shares or dispose of
any Shares, and the amount and timing of any such transactions, will depend upon
the Reporting Persons' individual continuing assessments of pertinent factors,
including the availability of Shares for purchase at particular price levels,
the Issuer's and the particular Reporting Person's business and prospects, other
business investment opportunities available to the particular Reporting Person,
economic conditions, stock market conditions, money market conditions, the
attitudes and actions of the Board of Directors and management of the Issuer,
the availability and nature of opportunities to dispose of the particular
Reporting Person's interest in the Issuer and other plans and requirements of
the particular Reporting Person. Depending upon his individual assessments of
these factors from time to time, each Reporting Person may change his present
intentions as stated above, including determining to acquire additional Shares
(by means of open market or privately negotiated purchases) or to dispose of
some or all of the Shares held by him or under his control.

     Certain of the Reporting Persons are also in the private equity business
and have mentioned, or may mention in the future, to the management of Issuer,
as such Reporting Persons mention to the management of many of the companies in
their portfolio, the fact that the Reporting Persons might be interested in a
joint venture or financing arrangement with the Issuer if an appropriate
opportunity mutually acceptable to both parties should arise.

     Except as set forth in this Item 4, the Reporting Persons have no present
plans or proposals that relate to or that would result in any of the actions
specified in clauses (a) through (j) of Item 4 of Schedule 13D of the Act.

Item 5.  Interest in Securities of the Issuer.
         ------------------------------------

Item 5 is hereby amended and restated in its entirety as follows:

(a) Percentage interest calculations for each Reporting Person are based upon
the Issuer having 220,388,579 total outstanding shares of common stock as of May
1, 2002, as reported on the Issuer's 10-Q filed with the Securities Exchange
Commission on May 14, 2002.
