(1)  On June 1, 2006, the "Company effected a two-for-one split of its Common
     Stock in the form of a stock dividend. Shareholders of the Company of
     record as of May 11, 2006 received one additional share for each share then
     owned. All share and per share information in this Amendment No. 5 reflects
     the stock split.

(2)  To the extent that the parties to the Stockholders Agreement may be deemed
     to constitute a "group" within the meaning of Section 13(d) of the Exchange
     Act, and the Reporting Persons may be deemed to share beneficial ownership
     of the shares of Common Stock owned by the other stockholder parties to the
     Stockholders Agreement, the Reporting Persons expressly disclaim beneficial
     ownership of any shares of Common Stock held by such other parties.



     This Amendment No. 5 amends and supplements the statement on Schedule 13D
initially filed by the Reporting Persons on April 11, 2003, as amended by
Amendment No. 1 filed on April 25, 2003, by Amendment No. 2 filed on February
17, 2004, by Amendment No. 3 filed on March 26, 2004, and by Amendment No. 4
filed on January 27, 2006 (the "Statement"). Information reported in the
Statement remains in effect except to the extent that it is amended, restated or
superseded by information contained in this Amendment No. 5. Capitalized terms
used and not defined in this Amendment No. 5 shall have the meanings set forth
in the Statement.

ITEM 2. IDENTITY AND BACKGROUND

     Item 2 of the Statement is hereby amended and supplemented as follows:

     Information with respect to the directors and executive officers of the
Reporting Persons set forth in Annex A to the Statement is hereby amended and
restated in its entirety as set forth in Annex A to this Amendment No. 5, and is
incorporated herein by reference.

     A joint filing agreement has been filed as Exhibit 11 to this Statement
pursuant to Rule 13d-1(k) promulgated under the Exchange Act.

ITEM 4. PURPOSE OF TRANSACTION

     Item 4 of the Statement is hereby amended and supplemented as follows:

     On September 14, 2006, the Reporting Persons completed the acquisition of a
total of 1,116,519 shares of Common Stock of the Company for an aggregate
purchase price of US$23,379,907.86, or US$20.94 per share. The acquisition of
the shares was made pursuant to, and in accordance with the terms and conditions
of, the Purchase Agreements (the "Purchase Agreements," and each separately, a
"Purchase Agreement"), dated September 14, 2006, by and among the Reporting
Persons, the selling shareholder specific to each Purchase Agreement (together,
the "Sellers," and each, a "Seller") and Penske Corporation, a Delaware
corporation. See also Item 6 to this Amendment No. 5, which is incorporated
herein by reference.

     The shares of Common Stock reported by the Reporting Persons were acquired
for the purpose of investment. Prior to entering into the Purchase Agreements,
the Reporting Persons owned in the aggregate 14,442,698 shares of Common Stock,
which they acquired in negotiated transactions from the Company and from
stockholders of the Company. This share number reflects the two-for-one split
effected by the Company of its Common Stock on June 1, 2006. Shareholders of the
Company of record as of May 11, 2006 received one additional share for each
share then owned. All share and per share information in this Amendment No. 5
reflects the stock split.

     The Reporting Persons may in the future seek to acquire, alone or in
conjunction with others, additional shares of Common Stock, through open market
purchases, negotiated transactions, tender offer, merger or otherwise. Future
purchases will depend on market, business and economic conditions, availability
of capital, factors relating to the Company (including the market price of the
Common Stock) and other factors that the Reporting Persons may consider
relevant. The Reporting Persons may seek at any time to dispose of all or a
portion of their shares of Common Stock, through open market transactions,
negotiated transactions or



otherwise. Future sales will depend on the factors set forth above. There can be
no assurance that the Reporting Persons will purchase any additional shares of
Common Stock or dispose of any shares of Common Stock.

ITEM 5. INTEREST IN SECURITIES OF THE ISSUER

     (a) The Reporting Persons beneficially own, within the meaning of Rule
13d-3 under the Exchange Act, an aggregate of 15,559,217 shares of Common Stock,
after giving effect to the acquisition reported in this Amendment No. 5. The
Common Stock owned by the Reporting Persons constitutes approximately 16.5% of
the Common Stock issued and outstanding after giving effect to the acquisition
reported in this Amendment No. 5, computed on the basis of 94,433,455 shares of
Common Stock issued and outstanding as of August 2, 2006 (as set forth in the
Company's quarterly report on Form 10-Q for the quarterly period ended June 30,
2006). To the Reporting Persons' knowledge, other persons named in Item 2 do not
beneficially own, within the meaning of Rule 13d-3 under the Exchange Act, any
Common Stock.

     To the extent that the parties to the Stockholders Agreement may be deemed
to constitute a "group" within the meaning of Section 13(d) of the Exchange Act,
and the Reporting Persons may be deemed to share beneficial ownership of the
shares of Common Stock owned by the other stockholder parties to the
Stockholders Agreement, the Reporting Persons expressly disclaim beneficial
ownership of any shares of Common Stock held by such other parties.

     (b) Mitsui Japan and Mitsui USA have the shared power to vote (or to direct
the vote) and to dispose (or direct the disposition) of 15,559,217 shares of
Common Stock, after giving effect to the acquisition reported in this Amendment
No. 5.

     (c) No transactions in the Common Stock were effected during the past sixty
days by the Reporting Persons.

from the respective Seller shares of Common Stock issued to such Seller by
Penske Associates, LLC, a Delaware limited liability company (or, in the case of
James Hislop, issued to such Seller by Penske Capital Partners LLC, a Delaware

Reporting Persons of 1,116,519 shares of Common Stock, or approximately 1.2% of
the Company, for an aggregate purchase price of US$23,379,907.86, or US$20.94
per share. With respect to these transactions,



Mitsui Japan purchased 893,215 of the subject shares, representing approximately
0.9% of the Company, and Mitsui USA purchased 223,304 of the subject shares,

Penske Capital LLC are free and clear of any and all Liens (as defined in the
Purchase Agreements), encumbrances, options and claims, and upon delivery of and

claims.
