Item 4.  Ownership.

         Reference is hereby made to Items 5-9 and 11 of page two (2) of
this Schedule 13G, which Items are incorporated by reference herein.  The
securities reflected in Items 5-9 and 11 of page two (2) of this Schedule 13G
are as of May 25, 2005.

         Under the definition of "beneficial ownership" in Rule 13d-3 under
the Securities Exchange Act of 1934, it is also possible that the individual
general partners, executive officers, and members of Steelhead might be
deemed the "beneficial owners" of some or all of the securities to which this
Schedule relates in that they might be deemed to share the power to direct
the voting or disposition of such securities. Neither the filing of this
Schedule nor any of its contents shall be deemed to constitute an admission
that any of such individuals is, for any purpose, the beneficial owner of any
of the securities to which this Schedule relates, and such beneficial
ownership is expressly disclaimed.

         The calculation of percentage of beneficial ownership in item 11 of
page two (2) was derived from the Issuer's Form 20-F for the fiscal year
ended December 31, 2004 filed with the Securities and Exchange Commission
(the "Commission") on March 31, 2005, in which the Issuer stated that the
number of Class A Common Shares outstanding as of December 31, 2004 was
194,509,790.

Item 5.  Ownership of Five Percent or Less of a Class.

         If this statement is being filed to report the fact that as of the
date hereof the reporting person has ceased to be the beneficial owner of
more than five percent of the class of securities, check the following [X].

Item 6.  Ownership of More Than Five Percent on Behalf of Another Person.

         Not applicable.

Item 7.  Identification and Classification of the Subsidiary Which
         Acquired the Security Being Reported on by the Parent Holding
         Company.
     
         Not applicable.

Item 9.  Notice of Dissolution of Group.

         Not applicable.

Item 10. Certifications.

         By signing below I certify that, to the best of my knowledge and
belief, the securities referred to above were acquired and are held in the
ordinary course of business and were not acquired and are not held for the
purpose of or with the effect of changing or influencing the control of the
issuer of the securities and were not acquired and are not held in connection
with or as a participant in any transaction having that purpose or effect.

                                   Signature
