the Senior Note Indenture referred to herein) and State Street Bank and Trust

                               W I T N E S S E T H

                  WHEREAS, the Company has heretofore executed and delivered to
the Senior Note Trustee a Senior Note Indenture dated as of May 18, 1998 (the
"SENIOR NOTE INDENTURE") providing for the issuance of an aggregate principal
amount of up to $550.0 million of 8-7/8% Senior Notes due 2008 (the "SENIOR
NOTES");

                  WHEREAS, the Company desires to clarify the definition of
"Lien" in Section 1.01 of the Senior Note Indenture;

                  WHEREAS, Section 9.01 of the Senior Note Indenture provides
that the Company, the Senior Note Guarantors and the Senior Note Trustee may
enter into a supplemental indenture, without the consent of any Holders, for the
purpose of curing any ambiguity, defect or inconsistency or for the purpose of
making any change that does not adversely affect the Holders of the Senior
Notes;

                  NOW, THEREFORE, in consideration of the foregoing and for
other good and valuable consideration, the receipt of which is hereby
acknowledged, the Company, the Senior Note Guarantors and the Senior Note
Trustee hereby agree as follows:

                  1.       Capitalized Terms. Capitalized terms used herein
without definition shall have the meanings assigned to them in the Senior Note
Indenture.

                  2.       Amendment to Senior Note Indenture. The definition of
"Lien" in Section 1.01 of the Senior Note Indenture is hereby amended by
inserting the following clause at the end thereof: ", but excluding any of the
foregoing arising as a result of a sale, contribution, disposition or other
transfer of accounts, chattel paper, payment intangibles, promissory notes
and/or related assets otherwise permitted under the terms hereof".

                  3.       NEW YORK LAW TO GOVERN. THE INTERNAL LAW OF THE STATE
OF NEW YORK SHALL GOVERN AND BE USED TO CONSTRUE THIS SUPPLEMENTAL SENIOR NOTE
INDENTURE BUT WITHOUT GIVING EFFECT TO APPLICABLE PRINCIPLES OF CONFLICTS OF LAW
TO THE EXTENT THAT THE APPLICATION OF THE LAWS OF ANOTHER JURISDICTION WOULD BE
REQUIRED THEREBY.

                                       1

                  4.       Counterparts. The parties may sign any number of

                  5.       Effect of Headings. The Section headings herein are
for convenience only and shall not affect the construction hereof.

                  6.       The Senior Note Trustee. The Senior Note Trustee
shall not be responsible in any manner whatsoever for or in respect of the
validity or sufficiency of this Supplemental Senior Note Indenture or for or in
respect of the recitals contained herein, all of which recitals are made solely
