delivery of this Amendment by the Company and the Parent Guarantor and the
performance of the Credit Agreement as amended by this Amendment (the "Amended

corporate powers and have been duly authorized by all necessary corporate
action on the part of the Company and the Parent Guarantor, as the case may be.

                 B.       No Conflict.  The execution and delivery by the
Company and the Parent Guarantor of this Amendment and the performance by the
Company and the Parent Guarantor of the Amended Agreement do not:

                          (1)     contravene such Obligor's Organic Documents;

                          (2)     contravene the Senior Indenture or the
Subordinated Indenture or contravene any other contractual restriction where
such a contravention has a reasonable possibility of having a Materially

or order binding on or affecting such Obligor or any of its Subsidiaries; or

                          (3)     result in, or require the creation or
imposition of, any Lien on any of such Obligor's properties or any of the
properties of any Subsidiary of such Obligor, other than pursuant to the Loan
Documents.

                 C.       Binding Obligation.  This Amendment has been duly
executed and delivered by the Company and the Parent Guarantor and this
Amendment and the Amended Agreement constitute the legal, valid and binding
obligations of the Company and the Parent Guarantor, enforceable against the
Company and the Parent Guarantor in accordance with their respective terms,
except as may be limited by bankruptcy, insolvency, reorganization, moratorium
or similar laws relating to or limiting creditors' rights generally and by
general principles of equity.

                 D.       Governmental Approval, Regulation, etc.  No
authorization or approval or other action by, and no notice to or filing with,
any governmental authority or regulatory body or any other Person is required
for the due execution, delivery or performance of this Amendment by the Company
or the Parent Guarantor.

                 The Company is a party to the Company Collateral Documents, in
each case as amended through the date hereof, pursuant to which the Company has
created Liens in favor of the Agent on certain Collateral to secure the

the date hereof pursuant to this Amendment.

                 Each Credit Support Party acknowledges and agrees that any of
the Credit Support Documents to which it is a party or otherwise bound shall
continue in full force and effect.  Each Credit Support Party hereby confirms
that each Credit Support Document to which it is a party or otherwise bound and
all Collateral encumbered thereby will continue to guaranty or secure, as the
case may be, the payment and performance of all obligations guaranteed or
secured thereby, as the case may be.

                 Each Credit Support Party (other than the Company and the
Parent Guarantor) acknowledges and agrees that (i) notwithstanding the
conditions to effectiveness set forth in this Amendment, such Credit Support
Party is not required by the terms of the Credit Agreement or any other Loan
Document to consent to the amendments to the Credit Agreement effected pursuant
to this Amendment and (ii) nothing in the Credit Agreement, this Amendment or
any other Loan Document shall be deemed to require the consent of such Credit 
Support Party to any future amendments to the Credit Agreement.
