those made part of the Indenture by reference to the Trust Indenture Act of 1939
(15 U.S. Code ss.ss. 77aaa-77bbbb) (the "TIA"), as in effect on the date of the
Indenture until such time as the Indenture is qualified under the TIA, and
thereafter as in effect on the date on which the Indenture is qualified under
the TIA. Notwithstanding anything to the contrary herein, the Notes are subject
to all such terms, and Holders of Notes are referred to the Indenture and the
TIA for a statement of such terms. The Notes are senior unsecured obligations of
the Company. Each Holder, by accepting a Note, agrees to be bound by all of the
terms and provisions of the Indenture, as the same may be amended from time to
time.

                  5. REDEMPTION.

                  (a) OPTIONAL REDEMPTION ON OR AFTER OCTOBER 1, 2007. Except as
set forth in CLAUSE (b) of this PARAGRAPH 5, the Company shall not have the
right to redeem any Notes pursuant to this PARAGRAPH 5 prior to October 1, 2007.
The Notes will be redeemable for cash at the option of the Company, in whole or
in part, at any time or from time to time, on and after October 1, 2007, at the
following Redemption Prices (expressed as percentages of the principal amount
thereof) if redeemed during the twelve-month period commencing on October 1 of
the year set forth below, plus, in each case, accrued and unpaid interest and
Additional Interest, if any, thereon to the Redemption Date:

                  YEAR                                               PERCENTAGE
                  ----                                               ----------
                  2007...........................................     105.125%
                  2008...........................................     102.563%

of the aggregate principal amount of the Notes issued under the Indenture at a
Redemption Price equal to 110.25% of the principal amount thereof, plus accrued
and unpaid interest and Additional Interest thereon, if any, to the Redemption
Date. In order to effect the foregoing redemption with the net cash proceeds of
any Public Equity Offering (a) at least 65% of the aggregate principal amount of

                                      -6-
<PAGE>

                  6. NOTICE OF REDEMPTION. Notice of redemption will be mailed
by first-class mail, postage prepaid, at least 30 days but not more than 60 days
before the Redemption Date to each Holder of Notes to be redeemed at such
Holder's registered address. If fewer than all of the Notes are to be redeemed
at any time, selection of Notes for redemption will be made by the Trustee
either (a) in compliance with the requirements of the principal national
securities exchange, if any, on which such Notes are listed or (b) if such Notes
are not then listed on a national securities exchange, on a PRO RATA basis, by
lot or by such other method as the Trustee in its sole discretion shall deem to
be fair and appropriate, PROVIDED that no partial redemption will reduce the
principal amount of a Note not redeemed to less than $1,000.

                  Except as set forth in the Indenture, if monies for the
redemption of the Notes called for redemption shall have been deposited with the
Paying Agent for redemption on such redemption date sufficient to pay such
Redemption Price plus accrued and unpaid interest and Additional Interest, if
any, the Notes called for redemption will cease to bear interest from and after
such Redemption Date, and the only remaining right of the Holders of such Notes
will be to receive payment of the Redemption Price plus accrued and unpaid
interest and Additional Interest, if any, as of the Redemption Date upon
surrender to the Paying Agent of the Notes redeemed.

                  7. OFFERS TO PURCHASE. Sections 4.15 and 4.16 of the Indenture
provide that upon the occurrence of a Change of Control and after certain Asset
Dispositions and subject to further limitations contained therein, the Company
will make an offer to purchase certain amounts of the Notes in accordance with
the procedures set forth in the Indenture.

                  8. DENOMINATIONS; TRANSFER; EXCHANGE. The Notes are in
registered form, without coupons, in denominations of $1,000 and integral
multiples thereof. A Holder shall register the transfer of or exchange of Notes
in accordance with the Indenture. The Registrar may require a Holder, among
other things, to furnish appropriate endorsements and transfer documents and to
pay any taxes, fees or similar governmental charges payable in connection
therewith as permitted by the Indenture. The Registrar need not register the
transfer of or exchange of any Notes or portions thereof selected for
redemption.

                  9. PERSONS DEEMED OWNERS. The registered Holder of a Note
shall be treated as the owner of it and the Notes of which it is composed for
all purposes.

                  10. UNCLAIMED MONEY. Subject to certain limitations set forth
in the Indenture, the Trustee and the Paying Agent shall pay to the Company,
upon written request from the Company any money deposited with the Trustee or
Paying Agent in trust for the payment of principal of, premium, if any, interest
and Additional Interest, if any, on the Notes that remains unclaimed for two
years after payment to the Holders is required; PROVIDED, HOWEVER, that the
Trustee and the Paying Agent before being required to make any payment may, but
need not, at the expense of the Company cause to be published once in a
newspaper of general circulation in the City of New York or mail to each Holder
entitled to such money notice that such money remains unclaimed and that after a
date specified therein, which shall be at least thirty (30) days from the date
of such publication or mailing, any unclaimed balance of such money then
remaining shall be repaid to the Company. After payment to the Company, Holders
entitled to money must look solely to the Company for payment as general
creditors unless an applicable abandoned property law designated another Person,
and all liability of the Trustee or Paying Agent with respect to such money
shall thereupon cease.

                                      -7-
<PAGE>

                  11. DISCHARGE PRIOR TO REDEMPTION OR MATURITY. If the Company
at any time deposits with the Trustee U.S. Legal Tender or U.S. Government
Obligations sufficient to pay the principal of, premium, if any, interest and
Additional Interest, if any, on the Notes to redemption or Maturity and complies
with the other provisions of the Indenture relating thereto, the Company shall
be deemed to have paid and discharged the entire Indebtedness represented by the
outstanding Notes, except for the rights of Holders to receive payments in
respect of the principal of, premium, if any, interest and Additional Interest,
if any, on the Notes when such payments are due from the deposits referred to
above.

                  12. AMENDMENT; SUPPLEMENT; WAIVER. Subject to certain
exceptions, the Indenture and the Notes may be amended or supplemented with the
written consent of the Holders of at least a majority in aggregate principal
amount of the Notes then outstanding, and any existing Default or Event of
Default or noncompliance with any provision may be waived with the written
consent of the Holders of a majority in aggregate principal amount of the Notes
then outstanding. Without consent of any Holder, the parties thereto may amend
or supplement the Indenture or the Notes to, among other things, cure any
ambiguity, defect or inconsistency, provide for uncertificated Notes in addition
to or in place of certificated Notes, provide for the assumption of the
Company's, the Parent's or a Subsidiary Guarantor's obligations in respect of
the Notes in case of a merger or consolidation, or sale of all or substantially
all of the assets of such Person in accordance with the Indenture, add
Subsidiary Guarantees, add to the covenants of the Parents, the Company or the
Restricted Subsidiaries of the Parent for the benefit of the Holders, surrender
any right or power conferred upon the Parent, the Company or a Restricted
Subsidiary of the Parent or comply with the TIA.

                  13. SUCCESSORS. When a successor assumes, in accordance with
the Indenture, all the obligations of its predecessor under the Notes and the
Indenture, the predecessor will be released from those obligations.

                  14. DEFAULTS AND REMEDIES. If an Event of Default occurs and
is continuing, the Trustee or the Holders of at least 25% in aggregate principal
amount of Notes then outstanding may declare all the Notes to be due and payable
in the manner, at the time and with the effect provided in the Indenture.
Holders of Notes may not enforce the Indenture except as provided in the
Indenture. The Trustee is not obligated to enforce the Indenture or the Notes
unless it has received indemnity or security satisfactory to it. The Indenture
permits, subject to certain limitations therein provided, Holders of a majority
in aggregate principal amount of the Notes then outstanding to direct the
Trustee in its exercise of any trust or power. The Trustee may withhold from
Holders of Notes notice of any continuing Default or Event of Default (except a
Default in payment of principal or interest) if it determines that withholding
notice is in their interest.

                  15. TRUSTEE DEALINGS WITH COMPANY. Subject to the terms of the
TIA and the Indenture, the Trustee under the Indenture, in its individual or any
other capacity, may become the owner or pledgee of Notes and may otherwise deal
with the Parent, the Company, their respective Subsidiaries or their respective
Affiliates as if it were not the Trustee.

                                      -8-
<PAGE>

                  16. NO RECOURSE AGAINST OTHERS. No director, officer,
employee, incorporator or stockholder of the Parent, the Company or any
Subsidiary Guarantor will have any liability for any obligations of the Parent,
the Company or any Subsidiary Guarantor under the Notes, the Parent Guarantee,
any Subsidiary Guarantee or this Indenture or for any claim based on, in respect
of, or by reason of such obligations or their creation. Each Holder of the Notes
by accepting a Note waives and releases all such liability. The waiver and
release are part of the consideration for issuance of the Notes.

                  17. GUARANTEES. Payment of principal, premium, if any, and
interest and Additional Interest, if any (including interest on overdue
principal and overdue interest, if lawful), is unconditionally guaranteed,
jointly and severally, by the Parent and each of the Subsidiary Guarantors.

                  18. ADDITIONAL RIGHTS OF HOLDERS OF TRANSFER RESTRICTED NOTES.
In addition to the rights provided to Holders of Notes under the Indenture,
Holders of Restricted Securities shall have all the rights set forth in the
Registration Rights Agreement dated as of the date of the Indenture, by and
