such Interest Payment Date shall be the next succeeding Business Day, and no
additional interest shall be paid in respect of such intervening period. The
interest rate borne by the Notes will be 8.125% per annum, in the case of the
8.125% Notes, and 8.75% per annum, in the case of the 8.75% Notes, respectively,
until the Notes are paid in full subject, however, to the following provisions.
In the event that (i) the Exchange Offer Registration Statement is not filed
with the SEC on or prior to the 120th calendar day following the original issue
of the Notes, (ii) the Exchange Offer Registration Statement has not been
declared effective by the SEC on or prior to the 180th calendar day following
the original issue of the Notes, (iii) the Exchange Offer is not consummated
within 60 calendar days after the Exchange Offer Registration Statement has been
declared effective by the SEC or (iv) a Shelf Registration Statement has not
been filed or declared effective on or prior to the applicable dates specified
in the Registration Rights Agreement (each such event in clauses (i) through
(iv) above and in the next succeeding paragraph below, a "REGISTRATION
DEFAULT"), the interest rate borne by the Notes shall be increased by an amount
("ADDITIONAL INTEREST") equal to an additional one quarter of one percent
(0.25%) per annum upon the occurrence of each Registration Default, which rate
will increase by an additional one quarter of one percent (0.25%) per annum for
each 90-day period that such Additional Interest

                                       8

<PAGE>

continues to accrue under any such circumstance, provided that the maximum
aggregate increase in the interest rate will in no event exceed one half of one
percent (0.5%) per annum; provided, that Additional Interest shall only be
payable in the case a Shelf Registration Statement is not declared effective as
aforesaid with respect to Notes that have the right to be included, and whose
inclusion has been requested, in the Shelf Registration Statement, in the manner
specified in the Registration Rights Agreement. Following the cure of all
Registration Defaults applicable to the respective Notes, the accrual of
Additional Interest will cease and the interest rate will revert to 8.125% per
annum for the 8.125% Notes and 8.75% per annum for the 8.75% Notes.

         If a Shelf Registration Statement is declared effective but shall
thereafter become unusable by a Holder of the Notes for any reason (whether or
not the Company had the right to prevent the Holders from distributing Notes
during any period pursuant to the Registration Rights Agreement) without being
succeeded within two Business Days by a post-effective amendment thereto which
cures the failure and that is immediately declared effective, the Notes included
in such Shelf Registration Statement will bear Additional Interest at a rate
equal to one quarter of one percent (0.25%) per annum for the first 90-day
period (or portion thereof) beginning on the date that such Shelf Registration
Statement ceases to be usable, which rate shall be increased by an additional
one quarter of one percent (0.25%) per annum at the beginning of each subsequent
90-day period, provided that the maximum aggregate increase in the interest rate
will in no event exceed one-half of one percent (0.5%) per annum. Upon the Shelf
Registration Statement once again becoming usable, the interest rate borne by
the Notes included therein will be reduced to the applicable original interest
rate if the Company is otherwise in compliance with the Registration Rights
Agreement with respect to such Notes at that time.

         For all purposes of this Seventh Supplemental Indenture, the term
interest shall include "Additional Interest".

         The amount of interest payable on the Notes will be computed on the
basis of a 360-day year of twelve 30-day months.

         The Company shall notify the Trustee within five Business Days after
each and every date (an "EVENT DATE") on which an event occurs in respect of
which Additional Interest is required to be paid. The obligation to pay
Additional Interest shall be deemed to accrue from and including the day
following the applicable Event Date. Additional Interest shall be paid by
depositing with the Trustee for the benefit of the Holders of the Notes entitled
to receive such Additional Interest, on or before the applicable Interest
Payment Date, immediately available funds in sums sufficient to pay the
Additional Interest then due. Additional Interest shall be payable to the Person
otherwise entitled to be paid the interest payable on the Notes on such Interest
Payment Date.

         Section 2.06. Redemption. The Notes will be redeemable in whole or in
part, at the option of the Company, at any time at a redemption price equal to
the greater of (1) 100% of the principal amount of the Notes to be redeemed and
(2) the sum of the present values of the remaining scheduled payments of
principal and interest thereon discounted to the redemption date on a semiannual
basis (assuming a 360-day year consisting of twelve 30-day months) at the
Treasury Rate, plus 37.5 basis points plus accrued interest thereon to the date
of redemption.

         Section 2.07. Transfer And Exchange.

         (a) Transfer and Exchange of Global Notes.

         A Global Note may not be transferred as a whole except by the
Depositary to a nominee of the Depositary, by a nominee of the Depositary to the
Depositary or to another nominee of the Depositary, or by the Depositary or any
such nominee to a successor Depositary or a nominee of such successor
Depositary. All Global Notes will be exchanged by the Company for Definitive
Notes if (i) the Company delivers to the Trustee notice from the Depositary
stating that it is unwilling or unable to continue to act as a clearing agency
for the Notes or is no longer a clearing agency registered under the Exchange
Act or other applicable law and, in either case, a successor Depositary is not
appointed by the Company within 90 days after the date of such notice; (ii) the
Company in its sole discretion determines that the Global Notes (in whole but
not in part) should be exchanged for Definitive Notes and delivers a written
notice to such effect to the Trustee; or (iii) an Event of Default with respect
to the Notes of such series has occurred and has not been cured, disregarding
for this purpose any requirement of notice or that the default exist for a
specified period of time; provided that in no event shall a Regulation S Global
Note be exchanged by the Company for Definitive Notes prior to the expiration of
the Restricted Period. Upon the occurrence of any of the preceding events,
Definitive Notes shall be issued in such names as the Depositary shall instruct
the Trustee.

         (b) Transfer and Exchange of Beneficial Interests in the Global Notes.

         The transfer and exchange of beneficial interests in the Global Notes
shall be effected through the Depositary in accordance with the provisions of
the Indenture and the applicable procedures of the Depositary. Transfers of
beneficial interests in the Global Notes also shall require compliance with
either subparagraph (i) or (ii) below, as applicable, as well as one or more of
the other following subparagraphs, as applicable:

               (i) Transfer of Beneficial Interests in the Same Type of Global
          Note. Beneficial interests in any Rule 144A Global Note may be
          transferred to Persons who take delivery thereof in the form of a
          beneficial interest in a Rule 144A Global Note in accordance with the
          transfer restrictions set forth in the Private Placement Legend.

          delivery thereof in the form of a beneficial interest in a Regulation
          S Global Note; provided, however, that prior to the expiration of the
          Restricted Period beneficial interests in the Regulation S Global Note
          may only be held through Euroclear of Clearstream, Luxembourg, if
          holders are Participants in such systems, or indirectly through
          organizations that are Participants in such systems. Beneficial
          interests in any Unrestricted Global Note may be transferred to
          Persons who take delivery thereof in the form of a beneficial interest
          in an Unrestricted Global Note. No written orders or instructions
          shall be required to be delivered to the Registrar to effect the
          transfers described in this Section 2.07(b)(i).

               (ii) All Other Transfers and Exchanges of Beneficial Interests in
          Global Notes. In connection with all transfers and exchanges of
          beneficial interests that are not subject to Section 2.07(b)(i) above,
          and, subject to any other requirement in this Section 2.07, the
          transferor of such beneficial interest must deliver to the Registrar:

          of another type in an amount equal to the beneficial interest to be
          transferred or exchanged and (2) instructions given in accordance with
          the Applicable Procedures containing information regarding the
          Participant account to be credited with such increase or (B), subject

          Depositary, Euroclear or Clearstream, Luxembourg to the Registrar
          containing information regarding the Person in whose name such

          that in no event shall Definitive Notes be issued upon the exchange of
          beneficial interests in the Regulation S Global Note prior to the
          expiration of the Restricted Period. Upon satisfaction of all of the
          requirements for transfer or exchange of beneficial interests in
          Global Notes contained herein and in the Indenture and the Notes or
          otherwise applicable under the Securities Act, the Trustee shall
          adjust the principal amount of the relevant Global Note(s) pursuant to
          Section 2.07(g) hereof.

               (iii) Transfer and Exchange of Beneficial Interests in a Rule
          144A Global Note or a Regulation S Global Note for Beneficial
          Interests in an Unrestricted Global Note. A beneficial interest in a
          Rule 144A Global Note may be exchanged by any holder thereof for a
          beneficial interest in an Unrestricted Global Note or transferred to a
          Person who

               Transmittal or via the Depositary's book-entry system that it is

         "THIS SECURITY HAS NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF

ACCEPTANCE HEREOF, AGREES TO BE BOUND BY AND TO COMPLY WITH THE PROVISIONS OF
SUCH REGISTRATION RIGHTS AGREEMENT.

         BECAUSE OF THE FOREGOING RESTRICTIONS, PURCHASERS ARE ADVISED TO

THE NOTES. INVESTORS SHOULD BE AWARE THAT THEY MAY BE REQUIRED TO BEAR THE
FINANCIAL RISKS OF THIS INVESTMENT FOR AN INDEFINITE PERIOD OF TIME."

                    (B) Notwithstanding the foregoing, any Note which is (i) a
               Regulation S Global Note (and any Note issued in exchange
               therefor or substitution thereof) after the Restricted Period,
               (ii) a Note which has been exchanged or transferred pursuant to
               the Exchange Offer Registration Statement or the Shelf
               Registration Statement, or (iii) a Note which has been
               transferred in accordance with Rule 144, provided that in such
               case an Opinion of Counsel is delivered which states that the
               Note does not have to bear the Private Placement Legend in the
               cases where such opinion is required under this Indenture, shall
               not bear the Private Placement Legend.

               (ii) Regulation S Global Note Legend. The Regulation S Global
          Note shall bear a legend in substantially the following form:

         "THE HOLDER OF THIS SECURITY IS ENTITLED TO THE BENEFITS OF A
REGISTRATION RIGHTS AGREEMENT (AS SUCH TERMS IS DEFINED IN THE INDENTURE
REFERRED TO ON THE REVERSE HEREOF) AND, BY ITS ACCEPTANCE HEREOF, AGREES TO BE
BOUND BY AND TO COMPLY WITH THE PROVISIONS OF SUCH REGISTRATION RIGHTS
AGREEMENT.

         DURING THE RESTRICTED PERIOD (AS DEFINED IN THE INDENTURE REFERRED TO
ON THE REVERSE HEREOF), INTERESTS IN THIS REGULATION S GLOBAL NOTE MAY ONLY BE
HELD THROUGH EUROCLEAR AND CLEARSTREAM, LUXEMBOURG."

         (g) 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 the 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

                                       18

<PAGE>

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 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 to reflect such increase.

         The Registrar shall have no obligation or duty to monitor, determine or
inquire as to compliance with any restrictions on transfer or exchange imposed
under the Indenture, this Seventh Supplemental Indenture or under applicable law
with respect to any transfer or exchange of any interest in any Note (including
any transfers between or among Participants, Indirect Participants or beneficial
owners of interests in any Global Note) other than to require delivery of such
certificates and other documentation or evidence as are expressly required by,
and to do so if and when expressly required by, the terms of the Indenture or
this Seventh Supplemental Indenture, and to examine the same to determine
substantial compliance as to form with the express requirements hereof.

                               EXECUTION OF NOTES

         Section 3.01. Execution of Notes. The Notes shall be executed as
follows:

         The Notes shall be signed on behalf of the Company by its Chairman of
the Board, its President, one of its Vice Presidents or its Treasurer, under its
corporate seal which may, but need not, be attested. Such signatures may be the
manual or facsimile signatures of the present or any future such officers. The
seal of the Company may be in the form of a facsimile thereof and may be
impressed, affixed, imprinted or otherwise reproduced on the Notes.
Typographical and other minor errors or defects in any such reproduction of the
seal or any such signature shall not affect the validity or enforceability of
any Note that has been duly authenticated and delivered by the Trustee.

         In case any officer of the Company who shall have signed any of the
Notes shall cease to be such officer before the Note so signed shall be
authenticated and delivered by the Trustee or disposed of by the Company, such
Note nevertheless may be authenticated and delivered or disposed of as though
the person who signed such Note had not ceased to be such officer of the
Company; and any Note may be signed on behalf of the Company by such persons as,
at the actual date of the execution of such Note, shall be the proper officers
of the Company, although at the date of the execution and delivery of this
Seventh Supplemental Indenture any such person was not such an officer.
