                                   WITNESSETH

         WHEREAS, the Company has issued its 2.00% Senior Subordinated
Convertible Notes due November 1, 2024 (the "NOTES") in the aggregate principal
amount of $345,000,000 under and pursuant to the Indenture, dated as of October

supplemented by the First Supplemental Indenture, dated as of October 29, 2004
(the "FIRST SUPPLEMENTAL INDENTURE," together with the Base Indenture, the
"INDENTURE"), among the Company, the Initial Subsidiary Guarantors and the
Trustee;

         WHEREAS, pursuant to Section 5.03 of the First Supplemental Indenture,
the Company is required to cause the New Subsidiary Guarantors to execute and
deliver to the Trustee this Second Supplemental Indenture pursuant to which the
New Subsidiary Guarantors shall become bound by the provisions of the Indenture
as a Subsidiary Guarantor;

         WHEREAS, pursuant to Section 10.01 of the First Supplemental Indenture,
the Trustee is authorized to execute and deliver this Second Supplemental
Indenture;

         WHEREAS, all things necessary for the execution of this Second
Supplemental Indenture and to make this Second Supplemental Indenture a valid
and binding agreement of the parties hereto have been done.

         NOW, THEREFORE, for and in consideration of the foregoing and for other
good and valuable consideration, the receipt of which is hereby acknowledged by
the Company, the Initial Subsidiary Guarantors, the New Subsidiary Guarantors,
and the Trustee, such parties hereby agree for the benefit of each other and the
equal and ratable benefit of the Holders of the Notes as follows:

                  Section 1.        Definitions.

                  Unless otherwise stated or unless the context shall otherwise
require, all capitalized terms used in this Second Supplemental Indenture shall
be given the same meanings as such terms are defined in the Indenture.

                  Section 2.        Subsidiary Guarantee.

                  (a) By execution and delivery of this Second Supplemental
Indenture, each of the New Subsidiary Guarantors hereby agrees to become a
Subsidiary Guarantor pursuant to the





Indenture and to assume all obligations of the Subsidiary Guarantors under the
Indenture (including, without limitation, the Subsidiary Guarantee as defined in
the Indenture) and the Notes, in each case, in accordance with the terms
thereof.

                  (b) Each of the New Subsidiary Guarantors hereby agrees that
its execution and delivery of this Second Supplemental Indenture shall evidence
its Subsidiary Guarantee as set forth in the Indenture without the need for any
further notation on the Notes and the delivery and authentication of any Note by
the Trustee under the Indenture, including any Note authenticated and delivered
on or prior to the date of this Second Supplemental Indenture, shall constitute
due delivery of the Subsidiary Guarantee set forth in this Second Supplemental
Indenture on behalf of each of the New Subsidiary Guarantors. Each of the
Initial Subsidiary Guarantors hereby agrees that its Subsidiary Guarantee set
forth in the Indenture shall remain in full force and effect.

                  Section 3.        Effectiveness and Validity.

                  (a) This Second Supplemental Indenture shall become effective
on the date first written above. The Indenture, as supplemented by this Second
Supplemental Indenture is in all respects ratified and confirmed hereby.
Following the effectiveness hereof, the Indenture shall be deemed supplemented
in accordance herewith, and this Second Supplemental Indenture shall form a part
of the Indenture for all purposes, and every Holder of Notes heretofore or
hereafter authenticated and delivered under the Indenture as supplemented by the
Second Supplemental Indenture shall be entitled to the benefit thereof and
hereof and be bound thereby and hereby.

                  (b) If an Officer of a Subsidiary Guarantor whose signature is
on the Indenture or the Second Supplemental Indenture no longer holds that
office at the time the Trustee authenticates such Notes or at any time
thereafter, such Subsidiary Guarantor's Subsidiary Guarantee shall be valid
nevertheless.

                  Section 4.        Solvency; No Fraudulent Transfer or
Conveyance.

                  Each of the New Subsidiary Guarantors, for the benefit of each
Holder, confirms that it is a solvent corporation, limited liability company, or
other entity and that the granting of the Subsidiary Guarantee is not made with
the purpose of defrauding any of its current creditors. Each of the Company and
the New Subsidiary Guarantors confirms that the Subsidiary Guarantee given by
each of the New Subsidiary Guarantors does not constitute a fraudulent transfer
or conveyance for purposes of the United States Bankruptcy Code, the Uniform
Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act or any similar
Federal or state law.

                  Section 5.        No Personal Liability of Directors,
Officers, Employees and Stockholders.

                  No director, officer, employee, incorporator or stockholder of
the Company or any Subsidiary Guarantor, as such, shall have any liability for
any obligations of the Company or the Subsidiary Guarantors under the Notes, the
Indenture or this Second Supplemental Indenture, the Subsidiary Guarantees, or
for any claim based on, in respect of, or by reason of, such


                                       2


obligations or their creation. The acceptance of a Note by each Holder of Notes
is deemed to be a waiver and release of all such liability. This waiver and
release are part of the consideration for issuance of the Subsidiary Guarantee
set forth in and evidenced by this Second Supplemental Indenture.

                  Section 6.        Governing Law.

                  THIS SECOND SUPPLEMENTAL INDENTURE AND THE NOTES AND THE
SUBSDIARY GUARANTEE SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE
LAWS OF THE STATE OF NEW YORK, WITHOUT GIVING EFFECT TO ITS CONFLICTS OF LAW
PRINCIPLES.

                  Section 7.        Successors.

                  All agreements of the Company and the Subsidiary Guarantors in
the Indenture, this Second Supplemental Indenture and the Notes shall bind their
respective successors. All agreements of the Trustee in this Second Supplemental
Indenture shall bind its successors.

                  Section 8.        Duplicate Originals.

                  The parties may sign any number of copies of this Second
Supplemental Indenture. Each signed copy shall be an original, but all of them
together represent the same instrument.

                  Section 9.        Severability.

                  In case any provision in this Second Supplemental Indenture
shall be invalid, illegal or unenforceable, the validity, legality and
enforceability of the remaining provisions of the Indenture, this Second
Supplemental Indenture and the Notes shall not in any way be affected or
impaired thereby, and a Holder shall have no claim therefor against any party
hereto.

                  Section 10.       Headings.

                  The headings of the sections of this Second Supplemental
Indenture have been inserted for convenience of reference only, are not to be
considered a part of this Second Supplemental Indenture and will in no way
modify or restrict any of the terms or provisions hereof.

                  Section 11.       Trustee.

                  The Trustee makes no representations as to the validity or
sufficiency of this Second Supplemental Indenture. The recitals and statements
herein are deemed to be those of the Company and the Subsidiary Guarantors and
not of the Trustee.
