Item 3.  SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION.

         As disclosed in the Schedule 13D filed by Fund V and Berkshire
Investors (collectively, the "Purchasers") on July 3, 2002, in a series of
transactions completed on June 27, 2002, the Purchasers purchased, in the
market, shares of Common Stock and shares of the Issuer's 6.25% Convertible
Preferred Stock (the "Preferred Stock"). At that time, Fund V purchased (i)
12,739,264 shares of Common Stock and (ii) 1,298,182 shares of Preferred Stock,
which were then convertible into 1,760,246.78 shares of Common Stock for
$74,615,525 in the aggregate. Berkshire Investors purchased (i) 606,636 shares
of Common Stock and (ii) 61,818 shares of Preferred Stock, which were then
convertible into 83,821.02 shares of Common Stock for $3,553,137 in the
aggregate. Berkshire Fund V Investment Corp. ("Investment Corp."), an affiliate
of Fund V and Fifth Berkshire, facilitated Fund V's purchase of its shares of
Common Stock and Preferred Stock by advancing Fund V the purchase price which
Fund V has repaid with funds from available funds and capital contributions from
its partners, representing the ultimate source of the funds. In addition, as
disclosed in the Schedule 13D filed by the Purchasers on July 3, 2002, in a
series of transactions completed on June 28, 2002, the Purchasers purchased, in
the market, 43,983 shares of the Issuer's 12 3/4% Senior Exchangeable Preferred
Stock (the "Exchangeable Preferred Stock") for $21,561,888 in the aggregate.
Shares of the Exchangeable Preferred Stock are not voting securities, and are
not convertible into voting securities and thus are not reported on for purposes
of this Schedule 13D.

         On August 15, 2002, each of the holders of Preferred Stock (including
Fund V and Berkshire Investors) received a dividend in the form of shares of
Common Stock on the Preferred Stock held by each such holder. Fund V received
410,215 shares of Common Stock and Berkshire Investors received 19,533 shares of
Common Stock.

         In a series of transactions completed on September 3, 2002, the
Purchasers purchased, in the market, shares of Common Stock. Fund V purchased
909,976 shares of Common stock for $1,639,394.56 in the aggregate, and Berkshire
Investors purchased 48,124 shares of Common stock for $86,699.44 in the
aggregate.

         On September 6, 2002, Fund VI purchased from Fund V and Investment
Corp. (1) 7,251,928 shares of Common Stock for $28,685,577.10, (2) 669,295
shares of Preferred Stock, which are currently convertible into 907,518.64
shares of Common Stock, for $10,913,202.15 and (3) 21,756 shares of Exchangeable
Preferred Stock for $10,611,071.88. In addition, on September 6, 2002, Berkshire
Investors purchased from Fund V and Investment Corp. (1) 78,204 shares of Common
Stock for $311,563.37, (2) 7,315 shares of Preferred Stock, which are currently
convertible into 9,918.64 shares of Common Stock, for $119,275.38 and (3) 238
shares of Exchangeable Preferred Stock for $116,195. Fund VI and Berkshire
Investors purchased all such shares with cash from available funds and capital
contributions from its partners.

         One of the members of the Board of Directors of the Issuer, Mr. Randall
A. Hack, also serves as an Advisory Director of Berkshire Partners. In this
capacity, Mr. Hack provides advice and counsel to Berkshire Partners and its
affiliates based upon his business and relevant industry experience. Mr. Hack
also participates with Berkshire Partners or its affiliates from time to time in
selected investments. The Reporting Persons have had discussions with Mr. Hack
with respect to their investment in the Issuer, and they expect that Mr. Hack
will participate in their investment in the Issuer. Any such investment would
be subject to the Issuer's insider trading policies.

Item 4.  PURPOSE OF TRANSACTION.

         The shares of Common Stock covered by this filing are being held for
investment purposes. The Reporting Persons will continue to monitor and evaluate
their investment in the Issuer in light of pertinent factors, including without
limitation the following: (a) the Issuer's business, operations, assets,
financial condition and prospects; (b) market, general economic and other
conditions; and (c) other investment opportunities available to the Reporting
Persons. In light of the foregoing factors, and the plans and requirements of
the Reporting Persons from time to time, including the plans described below,
the Reporting Persons may decide to (i) dispose of some or all of the shares of
the Preferred Stock that they beneficially own and/or the shares of Common Stock
into which such shares of the Preferred Stock are convertible or (ii) acquire
additional shares of Common Stock, shares of the Preferred Stock or other
securities of the Issuer.

         Earlier this calendar year, the Issuer and Berkshire Partners had a
number of discussions with respect to Berkshire Partners and one or more of its
affiliates making a direct investment in the Issuer. Due primarily to market
conditions at the time, the parties did not reach agreement on terms. Berkshire
Partners decided to purchase in the open market instead. Subsequent to the
filing of the Schedule 13D by the Fund V and Berkshire Investors on July 3,
2002, Carl Ferenbach, one of the Berkshire Principals, was elected to the Board
of Directors of the Issuer on July 18, 2002.

         Except as described above, the Reporting Persons do not have any plans
or proposals that relate to or would result in: (i) an extraordinary corporate
transaction, such as a merger, reorganization or liquidation, involving the
Issuer or any of its subsidiaries; (ii) a sale or transfer of a material amount
of assets of the issuer or of any of its subsidiaries; (iii) any change in the
present board of directors or management of the Issuer, including any plans or
proposals to change the number or term of directors; (iv) any material change in
the present capitalization or dividend policy of the Issuer; (v) any other
material change in the Issuer's business or corporate structure; (vi) changes in
the Issuer's charter, bylaws or instruments corresponding thereto or other
actions which may impede the acquisition of control of the Issuer by any person;
(vii) causing a class of securities of the Issuer to be delisted from a national
securities exchange or to cease to be authorized to be quoted in an inter-dealer
quotation system of a registered national securities association; (viii) a class
of equity securities of the Issuer becoming eligible for termination of
registration pursuant to Section 12(g)(4) of the Exchange Act; or (ix) any
action similar to any of those enumerated above.

Item 5.  INTEREST IN SECURITIES OF THE ISSUER.

         (a) As of the date hereof, the Reporting Persons collectively own an
aggregate of 16,577,815.80 shares of Common Stock, or approximately 7.78% of the
outstanding shares of Common Stock based on 212,990,370 shares of Common Stock
outstanding as of August 1, 2002 as reported by the Issuer on its quarterly
report on Form 10-Q filed with the Commission on August 14, 2002. The number of
shares and percentages included in the previous sentence do not include 904,529
shares of Common Stock held on the date hereof by certain Berkshire Principals,
other current or former employees of Berkshire Partners and trusts for the
benefit of such persons (collectively, the "Other Berkshire Holders"). Since
none of the Reporting Persons has voting or investment power with respect to the
Shares beneficially owned by the Other Berkshire Holders, the Reporting Persons
disclaim beneficial ownership of such shares.

          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.

         (b) Fund V has sole voting power with respect to 7,572,132.49 shares of
Common Stock and has sole dispositive power with respect to 7,572,132.49 shares
of Common Stock. Fund V is the direct beneficial owner of the 7,572,132.49
shares of Common Stock over which it has voting and dispositive power.

         As the sole general partner of Fund V, Fifth Berkshire may be deemed to
beneficially own 7,572,132.49 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 has sole voting power with respect to 8,159,446.64 shares of
Common Stock and has sole dispositive power with respect to 8,159,446.64 shares
of Common Stock. Fund VI is the direct beneficial owner of the 8,159,446.64
shares of Common Stock over which it has voting and dispositive power.

         As the sole general partner of Fund VI, Sixth Berkshire may be deemed
to beneficially own 8,159,446.64 shares of Common Stock held by Fund VI. The
filing of this Statement shall not be construed as an admission that Sixth
Berkshire is, for the purpose of Section 13(d) of the Exchange Act, the
beneficial owner of such shares held by Fund VI.

         Berkshire Investors has sole voting power with respect to 846,236.66
shares of Common Stock and has sole dispositive power with respect to 846,236.66
shares of Common Stock. Berkshire Investors is the direct beneficial owner of
the 846,236.66 shares of Common Stock over which it has voting and dispositive
power.

         By virtue of their positions as managing members of Fifth Berkshire,
Sixth Berkshire and Berkshire Investors, the Berkshire Principals may be deemed
to possess indirect beneficial ownership of the shares of Common Stock
beneficially owned by Fund V, Fund VI and Berkshire Investors. 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 or Berkshire
Investors, and, as a result, each Berkshire Principal disclaims beneficial
ownership of such shares of Common Stock.

         (c) Annex A attached hereto and incorporated herein by reference sets
forth all of the transactions in shares of Common Stock entered into by the
Reporting Persons since the most recent filing on Schedule 13D by the Reporting
Persons on July 3, 2002, including (i) the identity of the Reporting Person,
(ii) the date of the transaction, (iii) the number of shares of Common Stock
involved, (iv) the price per share and (v) where and how the transaction was
effected.
