and Registration Rights Agreement.

     The Issuer and each of the Guarantors party hereto (the "Guarantors") agree
that this letter agreement is being executed and delivered in connection with
the issue and sale of the Euro Senior Subordinated Notes pursuant to the
Purchase Agreement and to induce the Euro Initial Purchasers to purchase the
Securities thereunder and is being executed concurrently with the consummation

     1. Joinder. Each of the parties hereto hereby agrees to become bound by the
terms, conditions and other provisions of the Exchange and Registration Rights
Agreement with all attendant rights, duties and obligations stated therein, with
the same force and effect as if originally named as a Guarantor therein and as
if such party executed the Exchange and Registration Rights Agreement on the
date thereof.



     2. Representations, Warranties and Agreements of the Guarantors. Each
Guarantor represents and warrants to, and agrees with, the several Euro Initial
Purchasers on and as of the date hereof that such Guarantor has the corporate
power to execute and deliver this letter agreement and all corporate action
required to be taken by it for the due and proper authorization, execution,
delivery and performance of this letter agreement, and the consummation of the
transactions contemplated hereby has been duly and validly taken; this letter
agreement has been duly authorized, executed and delivered by such Guarantor and
constitutes a valid and legally binding agreement of such Guarantor enforceable
against such Guarantor in accordance with its terms.

     3. GOVERNING LAW. THIS LETTER AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED
IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK.

     4. Counterparts. This letter agreement may be executed in one or more
counterparts (which may include counterparts delivered by telecopier) and, if
executed in more than one counterpart, the executed counterparts shall each be
deemed to be an original, but all such counterparts shall together constitute
one and the same instrument.

     5. Amendments. No amendment or waiver of any provision of this letter
agreement, nor any consent or approval to any departure therefrom, shall in any
event be effective unless the same shall be in writing and signed by the parties
hereto.

     6. Headings. The headings herein are inserted for the convenience of
reference only and are not intended to be part of, or to affect the meaning or
interpretation of, this letter agreement.

                  If the foregoing is in accordance with your understanding of
our agreement, kindly sign and return to us a counterpart hereof, whereupon this
letter agreement will become a binding agreement between the Issuer, the
Guarantors party hereto and the several Euro Initial Purchasers in accordance
with its terms.
