                          FOURTH SUPPLEMENTAL INDENTURE

     This "Supplemental Indenture," dated as of December 19, 2001, among each of

     WHEREAS, the Company has heretofore executed and delivered to the Trustee
an indenture (as amended and supplemented, the "Indenture"), dated as of August
19, 1997 providing for the issuance of up to an aggregate principal amount of
$200,000,000 of 8-3/4% Senior Subordinated Notes due 2007 (the "Notes");

     WHEREAS, Section 4.15 of the Indenture provides that under certain
circumstances the Company is required to cause the Guarantors to execute and
deliver to the Trustee a supplemental indenture pursuant to which the Guarantors
shall unconditionally guarantee all of the Company's Obligations under the Notes
pursuant to a Guarantee on the terms and conditions set forth herein; and

     WHEREAS, pursuant to Section 9.1 of the Indenture, the Trustee is
authorized to execute and deliver this Supplemental Indenture.

     NOW THEREFORE, in consideration of the foregoing and for other good and
valuable consideration, the receipt of which is hereby acknowledged, the

benefit of the Holders of the Notes as follows:

     1. CAPITALIZED TERMS. Capitalized terms used herein without definition
shall have the meanings assigned to them in the Indenture.

     2. AGREEMENT TO GUARANTEE. The Guarantors hereby agree, jointly and
severally with all other Guarantors, to guarantee the Company's obligations
under the Notes on the terms and subject to the conditions set forth in Article
11 of the Indenture and to be bound by all other applicable provisions of the
Indenture. The obligations of the Guarantors hereunder shall be junior and
subordinated to the Senior Debt of such Guarantors in the manner and to the

obligations or their creation. Each Holder

govern and be used to construe this Supplemental Indenture.

     5. COUNTERPARTS. The parties may sign any number of copies of this
