BCP Caylux Holdings Luxembourg S.C.A. S-4 Registration of securities issued in business combination transactions

                            FORM OF LETTER AGREEMENT


                                                                   June 29, 2004


                  Reference is made to the Loan Agreement dated as of June 8,
2004 among inter alia BCP Caylux Holdings Luxembourg S.C.A. and the Lenders
party thereto (the "Term C Loan Agreement"). All terms defined in the Term C
Loan Agreement shall have the same meanings when issued hereto unless otherwise
defined herein.

                  As a result of a drafting error, the definition in the Term C
Loan Agreement of "Excluded Indebtedness" is different from the same definition
contained in the Credit Agreement dated as of April 6, 2004 governing the first
lien debt of the Borrower (the "Credit Agreement") and thus the Indebtedness
that comes within the Credit Agreement definition may not come within the Term C
Loan Agreement definition.

                  The Term C Loan Agreement shall be amended by changing the
definition therein of Excluded Indebtedness to read substantively the same as in
the Credit Agreement;

                  "Excluded Indebtedness" shall mean all Indebtedness permitted
to be incurred pursuant to Section 6.01 (other than Sections 6.01(o) and (s)) of
the Credit Agreement as in effect on the Closing Date.


                  Given the time requirements of the client, you are requested
to insert your institution's name on the signature block and execute the
enclosed copy of this letter to acknowledge your agreement thereto and send to
Sean Geary at White & Case by fax (212-819-7826) or email (sgeary@whitecase.com)
no later than 5:00 p.m. on Wednesday, June 30, 2004.


                                                     Very truly yours,





                                                     ___________________________
