Interest on the Notes will accrue from the most recent date to which interest
has been paid or, if no interest has been paid, from the date of original
issuance; provided that if there is no existing Default or Event of Default in
the payment of interest, and if this Note is authenticated between a record date

interest shall accrue from such next succeeding Interest Payment Date, except in
the case of the original issuance of Notes, in which case interest shall accrue
from the date of authentication. The Company shall pay interest (including
post-petition interest in any proceeding under any Bankruptcy Law) on overdue
principal and premium, if any, from time to time on demand at a rate that is the
rate then in effect; it shall pay interest (including post-petition interest in
any proceeding under any Bankruptcy Law) on overdue installments of interest and
Liquidated Damages (without regard to any applicable grace periods) from time to
time on demand at the same rate to the extent lawful. Interest will be computed

the meanings specified in the Indenture.

         Until this Regulation S Temporary Global Note is exchanged for one or
more Regulation S Permanent Global Notes, the Holder hereof shall not be
entitled to receive payments of interest or Liquidated Damages, if any, hereon
although interest and Liquidated Damages, if any, will continue to accrue; until
so exchanged in full, this Regulation S Temporary Global Note shall in all other
respects be entitled to the same benefits as other Notes under the Indenture.

         This Regulation S Temporary Global Note is exchangeable in whole or in
part for one or more Regulation S Permanent Global Notes only (i) on or after
