                           (1) Except as permitted by subparagraph (2) below,
         each Restricted Note (and all Series A Notes issued in exchange
         therefor or substitution thereof) shall bear a legend in substantially
         the following form:

                  THIS SECURITY HAS NOT BEEN REGISTERED UNDER THE SECURITIES ACT
OF 1933, AS AMENDED (THE "SECURITIES ACT"), OR THE SECURITIES LAWS OF ANY STATE
OR OTHER JURISDICTION. NEITHER THIS SECURITY NOR ANY INTEREST OR PARTICIPATION
HEREIN MAY BE REOFFERED, SOLD, ASSIGNED, TRANSFERRED, PLEDGED, ENCUMBERED OR
OTHERWISE DISPOSED OF IN THE ABSENCE OF SUCH REGISTRATION OR UNLESS SUCH
TRANSACTION IS EXEMPT FROM, OR NOT SUBJECT TO, SUCH REGISTRATION. THE HOLDER OF
THIS SECURITY BY ITS ACCEPTANCE HEREOF AGREES TO OFFER, SELL OR OTHERWISE
TRANSFER SUCH SECURITY, PRIOR TO THE DATE (THE "RESALE RESTRICTION TERMINATION
DATE") WHICH IS TWO YEARS AFTER THE LATER OF THE ORIGINAL ISSUE DATE HEREOF AND
THE LAST DATE ON WHICH EITHER THE COMPANY OR ANY AFFILIATE OF THE COMPANY WAS
THE OWNER OF THIS SECURITY (OR ANY PREDECESSOR OF SUCH SECURITY), ONLY (A) TO
THE COMPANY, (B) PURSUANT TO A REGISTRATION STATEMENT THAT HAS BEEN DECLARED
EFFECTIVE UNDER THE SECURITIES ACT, (C) FOR SO LONG AS THE NOTES ARE ELIGIBLE
FOR RESALE PURSUANT TO RULE 144A, TO A PERSON IT REASONABLY BELIEVES IS A
"QUALIFIED INSTITUTIONAL BUYER" AS DEFINED IN RULE 144A UNDER THE SECURITIES ACT
THAT PURCHASES FOR ITS OWN ACCOUNT OR FOR THE ACCOUNT OF A QUALIFIED
INSTITUTIONAL BUYER TO WHOM NOTICE IS GIVEN THAT THE TRANSFER IS BEING MADE IN
RELIANCE ON RULE 144A, (D) PURSUANT TO OFFERS AND SALES THAT OCCUR OUTSIDE THE
UNITED STATES WITHIN THE MEANING OF REGULATION S UNDER THE SECURITIES ACT, OR
(E) PURSUANT TO ANY OTHER AVAILABLE EXEMPTION FROM THE REGISTRATION REQUIREMENTS
OF THE SECURITIES ACT, SUBJECT TO THE RIGHT OF THE COMPANY AND THE TRUSTEE PRIOR
TO ANY SUCH OFFER, SALE OR TRANSFER PURSUANT TO CLAUSES (D) OR (E) TO REQUIRE
THE DELIVERY OF AN OPINION OF COUNSEL, CERTIFICATION AND/OR OTHER INFORMATION
SATISFACTORY TO EACH OF THEM. THIS LEGEND WILL BE REMOVED UPON THE REQUEST OF
THE HOLDER AFTER THE RESALE RESTRICTION TERMINATION DATE.

                           (2) Exchange Notes shall not bear the Private
         Placement Legend. The Private Placement Legend required for a
         Restricted Note may be removed from a Series A Note if there is
         delivered to the Company such satisfactory evidence, which may include
         an opinion of independent counsel licensed to practice law in the State
         of New York, as may be reasonably required by the Company that neither
         such legend nor the restrictions on transfer set forth therein are
         required to ensure that transfers of such Series A will not violate the
         registration requirements of the Securities Act. Upon provision of such
         satisfactory evidence, the Trustee, at the direction of the Company,
         shall authenticate and deliver in exchange for such Series A Note
         another Series A Note or Series A Notes having an equal aggregate
         principal amount that does not bear such legend. If such a legend
         required for a Restricted Note has been removed from a Series A Note as
         provided above, it shall not be a Restricted Note and no other Series A
         Note issued in exchange for all or any part of such Series A Notes
         shall bear such legend, unless the Company has reasonable cause to
         believe that such other Series A Note is a "restricted security" within
         the


                                       9
<PAGE>

         meaning of Rule 144 and instructs the Trustee to cause a legend to
         appear thereon.

                           (b) Regulation S Legend. Each Regulation S Note (and
all Series A Notes issued in exchange therefor or substitution thereof) shall
bear a legend in substantially the following form:

                  THIS SECURITY HAS NOT BEEN REGISTERED UNDER THE UNITED STATES
SECURITIES ACT OF 1933 (THE "SECURITIES ACT") AND MAY NOT BE OFFERED, SOLD OR
DELIVERED IN THE UNITED STATES OR TO, OR FOR THE BENEFIT OF, ANY U.S. PERSONS
UNLESS THIS SECURITY HAS BEEN REGISTERED UNDER THE SECURITIES ACT OR AN
EXEMPTION FROM THE REGISTRATION REQUIREMENTS THEREOF IS AVAILABLE.

THIS SECURITY MAY NOT LAWFULLY BE OFFERED OR SOLD TO PERSONS IN THE UNITED
KINGDOM EXCEPT IN CIRCUMSTANCES WHICH DO NOT RESULT IN AN OFFER TO THE PUBLIC IN
THE UNITED KINGDOM WITHIN THE MEANING OF THE PUBLIC OFFERS OF SECURITIES
REGULATIONS 1995 (THE "REGULATION S") AND WHICH ARE OTHERWISE IN COMPLIANCE WITH
ALL APPLICABLE PROVISIONS OF THE REGULATIONS.

                           (c) Global Note Legend. Each Global Note shall bear a
legend in substantially the following form:

"THIS GLOBAL NOTE IS HELD BY THE DEPOSITARY (AS DEFINED IN THE INDENTURE
GOVERNING THIS NOTE) OR ITS NOMINEE IN CUSTODY FOR THE BENEFIT OF THE BENEFICIAL
OWNERS HEREOF, AND IS NOT TRANSFERABLE TO ANY PERSON UNDER ANY CIRCUMSTANCES
EXCEPT THAT (I) THE TRUSTEE MAY MAKE SUCH NOTATIONS HEREON AS MAY BE REQUIRED
PURSUANT TO SECTION 2.07 OF THE ORIGINAL INDENTURE, (II) THIS GLOBAL NOTE MAY BE
EXCHANGED IN WHOLE BUT NOT IN PART PURSUANT TO SECTION 2.11(c) OF THE ORIGINAL
INDENTURE, (III) THIS GLOBAL NOTE MAY BE DELIVERED TO THE TRUSTEE FOR
CANCELLATION PURSUANT TO SECTION 2.08 OF THE ORIGINAL INDENTURE AND (IV) EXCEPT
AS OTHERWISE PROVIDED IN SECTION 2.11 OF THE ORIGINAL INDENTURE, THIS SECURITY
MAY BE TRANSFERRED, IN WHOLE BUT NOT IN PART, ONLY TO ANOTHER NOMINEE OF THE
DEPOSITARY OR TO A SUCCESSOR DEPOSITARY OR TO A NOMINEE OF SUCH SUCCESSOR
DEPOSITARY."

                           (d) DTC Legend. Each Global Note for which DTC is
acting as the Depositary shall bear a legend in the following form:

                  UNLESS THIS CERTIFICATE IS PRESENTED BY AN AUTHORIZED
REPRESENTATIVE OF THE DEPOSITORY TRUST COMPANY, 55 WATER STREET, NEW YORK, NEW
YORK 10004, TO THE COMPANY OR ITS AGENT FOR REGISTRATION OR TRANSFER, EXCHANGE
OR PAYMENT, AND ANY CERTIFICATE ISSUED IS REGISTERED IN THE NAME OF CEDE & CO.
OR IN SUCH OTHER NAME AS IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF CEDE &
CO., AND ANY PAYMENT IS MADE TO CEDE & CO. OR TO SUCH OTHER ENTITY AS IS
REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF CEDE & CO., ANY TRANSFER, PLEDGE OR
OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON IS


                                       10

WRONGFUL BECAUSE THE REGISTERED OWNER HEREOF, CEDE & CO., HAS AN INTEREST
HEREIN.

                  SECTION 3.7 Cancellation and/or Adjustment of Global Notes. At
such time as all beneficial interests in a particular Global Note have been
exchanged for Definitive Notes or a particular Global Note has been redeemed,
repurchased or canceled in whole and not in part, each such Global Note shall be
returned to or retained and canceled by the Trustee in accordance with Section
2.08 of the Original Indenture. At any time prior to such cancellation, if any
beneficial interest in a Global Note is exchanged for or transferred to a Person
who will take delivery thereof in the form of a beneficial interest in another
Global Note or for Definitive Notes, the principal amount of Notes represented
by such Global Note shall be reduced accordingly and an endorsement shall be
made on such Global Note by the Trustee or by the Depositary at the direction of
the Trustee to reflect such reduction; and if the beneficial interest is being
exchanged for or transferred to a Person who will take delivery thereof in the
form of a beneficial interest in another Global Note, such other Global Note
shall be increased accordingly and an endorsement shall be made on such Global
Note by the Trustee or by the Depositary at the direction of the Trustee to
reflect such increase.
