                                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

          other currency in any legal exchange market in such jurisdiction in
          accordance with normal commercial practice; or

                 (B)   a declaration of banking moratorium or any suspension of
          payments by banks in such jurisdiction or the imposition by such
          jurisdiction or any governmental authority thereof of any moratorium
          on, the required

                                       -4-
<Page>

          rescheduling or restructuring of, or required approval of payments on,
          any indebtedness in such jurisdiction; or

                 (C)   any expropriation, confiscation, nationalization or
          requisition by such country or any governmental authority that
          directly or indirectly deprives a Borrower of any assets or their use,
          or of the ability to operate its business or a material part thereof;
          or

                 (D)   any war (whether or not declared), insurrection,
          revolution, hostile act, civil strife or similar events occurring in
          such jurisdiction which has the same effect as the events described in
          clause (A), (B) or (C) above (in each of the cases contemplated in
          clauses (A) through (D) above, to the extent occurring or existing on
          or at any time after the date of this Agreement); and

          (x)    any other circumstance (including, without limitation, any
     statute of limitations) or any existence of or reliance on any
     representation by the Collateral Agent that might otherwise constitute a
     defense to, or a legal or equitable discharge of, any Borrower or any
     Guarantor or any other guarantor or surety.

          Each Guarantor expressly authorizes the Secured Parties to take and
hold security for the payment and performance of the Guaranteed Obligations, to
exchange, waive or release any or all such security (with or without
consideration), to enforce or apply such security and direct the order and
manner of any sale thereof in their sole discretion or to release or substitute
any one or more other guarantors or obligors upon or in respect of the
Guaranteed Obligations, all without affecting the obligations of the Guarantor
hereunder.

          Without limiting the generality of the foregoing, with respect to any
Guaranteed Obligations that, in accordance with the express terms of any
agreement pursuant to which such Guaranteed Obligations were created, were
denominated in Dollars or any currency other than the currency of the
jurisdiction where a Borrower is principally located, the Guarantor guarantees
that it shall pay the Collateral Agent strictly in accordance with the express
terms of such agreement, including in the amounts and in the currency expressly
agreed to thereunder, irrespective of and without giving effect to any laws of
the jurisdiction where any Borrower is principally located in effect from time
to time, or any order, decree or regulation in the jurisdiction where any
Borrower is principally located.

          (b)    To the fullest extent permitted by applicable law, each
Guarantor waives any defense based on or arising out of any defense of any
Borrower or other Loan Party or the unenforceability of the Guaranteed
Obligations or any part thereof from any cause, or the cessation from any cause
of the liability of any Borrower or other Loan Party, other than the
indefeasible payment in full in cash of all the Guaranteed Obligations. The
Collateral Agent and the other Secured Parties may, at their election, foreclose
on any security held by one or more of them by one or more judicial or
nonjudicial sales, accept an assignment of any such security in lieu of
foreclosure, compromise or adjust any part of the Guaranteed Obligations, make
any other accommodation with any Borrower or other Guarantor or exercise any
other right or remedy available to them against any Borrower or other Guarantor,
without affecting or impairing in any way the liability of any Guarantor
hereunder except to the extent the Guaranteed Obligations

                                       -5-
<Page>

have been fully and indefeasibly paid in full in cash. To the fullest extent
permitted by applicable law, each Guarantor waives any defense arising out of
any such election even though such election operates, pursuant to applicable
law, to impair or to extinguish any right of reimbursement or subrogation or
other right or remedy of any Guarantor against any Borrower, as the case may be,
or any security.

          SECTION 2.04 REINSTATEMENT. Each Guarantor agrees that its guarantee
hereunder shall continue to be effective or be reinstated, as the case may be,
if at any time payment, or any part thereof, of any Guaranteed Obligation is
rescinded or must otherwise be restored by the Administrative Agent or any other
Secured Party upon the bankruptcy or reorganization of a Borrower, any other
Loan Party, or otherwise.

          SECTION 2.05 AGREEMENT TO PAY; SUBROGATION. In furtherance of the
foregoing and not in limitation of any other right that the Collateral Agent or
any other Secured Party has at law or in equity against any Guarantor by virtue
hereof, upon the failure of any Borrower to pay any Guaranteed Obligation when
and as the same shall become due, whether at maturity, by acceleration, after
notice of prepayment or otherwise, each Guarantor hereby promises to and will
forthwith pay, or cause to be paid, to the Collateral Agent for distribution to
the applicable Secured Parties in cash the amount of such unpaid Guaranteed
Obligation. Upon payment by a Guarantor of any sums to the Collateral Agent as
provided above, all rights of such Guarantor against any Borrower, any other
Loan Party arising as a result thereof by way of right of subrogation,
contribution, reimbursement, indemnity or otherwise shall in all respects be
subject to Article V.

          SECTION 2.06 INFORMATION. Each Guarantor assumes all responsibility
for being and keeping itself informed of the financial condition and assets of
the respective Borrowers and other Loan Parties, and of all other circumstances
bearing upon the risk of nonpayment of the Guaranteed Obligations and the
nature, scope and extent of the risks that such Guarantor assumes and incurs
hereunder, and agrees that none of the Collateral Agent or the other Secured
Parties will have any duty to advise any Guarantor of information known to it or
any of them regarding such circumstances or risks.

          SECTION 2.07 DEMAND. Notwithstanding any other provision hereof,
demand may only be made under the Guarantee provided for in this Article II by
the Collateral Agent.

                                  ARTICLE III.

                              PLEDGE OF SECURITIES

          SECTION 3.01 PLEDGE. As security for the payment or performance, as
the case may be, in full of its Secured Obligations on and after the
Restructuring Date, each Guarantor (to the extent owning Pledged Stock) hereby
assigns and pledges to the Collateral Agent (to be held until the First Lien
Termination Date by the First Lien Collateral Agent as collateral agent for the
ratable benefit of the First Lien Secured Parties and as bailee for the
Collateral Agent as collateral agent for the ratable benefit, on a basis junior
and subordinated (in Lien only) to the First Lien Secured Parties, on the basis
set forth on the signature page executed by the First Lien Collateral Agent (in
such capacity, the "BAILEE")), its successors and assigns, for the ratable

                                       -6-
<Page>

benefit, on a basis junior and subordinated (in Lien only) to the First Lien
Secured Parties, of the Second Lien Secured Parties, and hereby grants, with
effect on and after the Restructuring Date, to the Collateral Agent, its
successors and assigns, for the ratable benefit, on a basis junior and
subordinated (in Lien only) to the First Lien Secured Parties, of the Second
Lien Secured Parties, a security interest in all of such Guarantor's right,
title and interest in, to and under (a) the Equity Interests directly owned by
it on the Restructuring Date (which shall be listed on SCHEDULE I) and any other
Equity Interests obtained in the future by the Guarantor and any certificates
representing all such Equity Interests (the "PLEDGED STOCK"); PROVIDED that the
Pledged Stock shall not include (x) to the extent applicable law requires that a
Subsidiary of the Guarantor issue directors' qualifying shares, such shares or
nominee or other similar shares and (y) any Equity Interest that constitutes an
unlimited liability interest; (b) subject to Section 3.05, all payments of
dividends, cash, instruments and other property from time to time received,
receivable or otherwise distributed in respect of, in exchange for or upon the
conversion of, and all other proceeds received in respect of, the Pledged Stock;
(c) subject to Section 3.05, all rights and privileges of the Guarantor with
respect to the Pledged Stock and other property referred to in clause (b) above;
and (d) all proceeds of any of the foregoing (the items referred to in clauses
(a) through (d) above being collectively referred to as the "COLLATERAL").

          TO HAVE AND TO HOLD the Collateral, together with all right, title,
interest, powers, privileges and preferences pertaining or incidental thereto,
unto the Collateral Agent, its successors and assigns, for the ratable benefit,
on a basis junior and subordinated (in Lien only) to the First Lien Secured
Parties, of the Second Lien Secured Parties, forever; SUBJECT, HOWEVER, to the
terms, covenants and conditions hereinafter set forth.

          SECTION 3.02 DELIVERY OF THE COLLATERAL. (a) Each Guarantor has,
prior to the Restructuring Date, delivered to the First Lien Collateral Agent
all of the Pledged Stock owned by it on such date (with the First Lien
Collateral Agent to hold same as Bailee on and after the Restructuring Date to
the extent the same remains outstanding) and agrees promptly to deliver or cause
to be delivered on and after the Restructuring Date to the Bailee (or after the
occurrence of the First Lien Termination Date, the Collateral Agent), for the
ratable benefit, on a basis junior and subordinated (in Lien only) to the First
Lien Secured Parties, of the Second Lien Secured Parties, any and all Pledged
Stock then or thereafter acquired by it.

          (b)    Upon delivery to the Bailee or Collateral Agent, as the case
may be, (i) any Pledged Stock required to be delivered pursuant to the foregoing
paragraph (a) of this Section 3.02 shall be accompanied by stock powers duly
executed in blank or other instruments of transfer reasonably satisfactory to
the Bailee or Collateral Agent, as the case may be, and by such other
instruments and documents as the Bailee or Collateral Agent, as the case may be,
may reasonably request and (ii) all other property comprising part of the
Collateral delivered pursuant to the terms of this Agreement shall be
accompanied to the extent necessary to perfect the security interest in or allow
realization on the Collateral by proper instruments of assignment duly executed
by the Guarantor and such other instruments or documents as the Bailee or
Collateral Agent, as the case may be, may reasonably request. Each delivery of
Pledged Stock shall be accompanied by a schedule describing the securities,
which schedule shall be attached hereto as SCHEDULE I and made a part hereof;
PROVIDED that failure to attach any such schedule hereto shall not affect the
validity of such pledge of such Pledged Stock. Each schedule so delivered shall
supplement any prior schedules so delivered.

          SECTION 3.03 REPRESENTATIONS, WARRANTIES AND COVENANTS. Each
Guarantor represents, warrants and covenants to and with the Collateral Agent,
for the ratable benefit of the Second Lien Secured Parties, that:

          (a)    SCHEDULE I correctly sets forth the percentage of the issued

     Permitted Liens and (iv) subject to the rights (if any) of such Guarantor
     under the Loan Documents to dispose of Collateral, will defend its title or
     interest hereto or therein against any and all Liens (other than Permitted
     Liens), however arising, of all persons;

          (d)    except for restrictions and limitations imposed by the CA Loan
     Documents, the Loan Documents, or securities laws generally or otherwise
     permitted to exist pursuant to the terms of the Loan Agreement, the
     Collateral is and will continue to be freely transferable and assignable,
     and none of the Collateral is or will be subject to any option, right of
     first refusal, shareholders agreement, charter or by-law provisions or
     contractual restriction of any nature that might, in any material respect,
     prohibit, impair, delay or adversely affect the pledge of such Collateral
     hereunder, the sale or disposition thereof pursuant hereto or the exercise
     by the Collateral Agent of rights and remedies hereunder;

          (e)    such Guarantor has the power and authority to pledge the
     Collateral pledged by it hereunder in the manner hereby done or

     of the pledge effected by such Guarantor hereunder (other than such as have
     been obtained and are in full force and effect);

          (g)    by virtue of the execution and delivery by such Guarantor of
     this Agreement, on the Restructuring Date with respect to any Pledged Stock
     then held by the First Lien Collateral Agent and with respect to any other
     Pledged Stock when delivered to the Bailee or Collateral Agent, as the case
     may be, for the benefit of the Second Lien Secured Parties, in accordance
     with this Agreement, the Collateral Agent will obtain, for

                                       -8-
<Page>

     the benefit of the Second Lien Secured Parties, a legal, valid and
     perfected second priority lien upon and security interest in such Pledged
     Stock as security for the payment and performance of the Obligations; and

          (h)    the pledge effected by such Guarantor hereunder is effective to
     vest in the Collateral Agent, for the ratable benefit, on a basis junior
     and subordinated (in Lien only) to the First Lien Secured Parties, of the
     Second Lien Secured Parties, the rights of the Collateral Agent in the
     Collateral as set forth herein.

          SECTION 3.04 REGISTRATION IN NOMINEE NAME; DENOMINATIONS. The
Collateral Agent, on behalf of the Second Lien Secured Parties, shall have the
right (in its sole and absolute discretion), after the occurrence of the First
Lien Termination Date, to hold the Pledged Stock in the name of the respective
Guarantor, endorsed or assigned in blank or in favor of the Collateral Agent
and, if an Event of Default shall have occurred and be continuing, in its own
name as pledgee or the name of its nominee (as pledgee or as sub-agent). Each
Guarantor will promptly give to the Collateral Agent copies of any notices or
other communications received by it with respect to Pledged Stock registered in
the name of such Guarantor.

          SECTION 3.05 VOTING RIGHTS, DIVIDENDS, ETC. (a) Unless and until a
Noticed Event of Default shall have occurred and be continuing:

          (i)    Each Guarantor shall be entitled to exercise any and all voting
     and/or other consensual rights and powers inuring to an owner of Pledged
     Stock pledged by it or any part thereof for any purpose consistent with the
     terms of this Agreement, the Credit Agreement, the Loan Agreement and the
     other CA Loan Documents and Loan Documents; PROVIDED that such rights and
     powers shall not be exercised in any manner that could reasonably be
     expected to materially and adversely affect the rights inuring to a holder
     of any Pledged Stock, the rights and remedies of any of the Bailee, the
     Collateral Agent or the other Second Lien Secured Parties under this
     Agreement, the Credit Agreement, the Loan Agreement, or any other CA Loan
     Document or Loan Document or the ability of the Second Lien Secured Parties
     to exercise the same.

          (ii)   The Collateral Agent shall promptly execute and deliver to each
     Guarantor, or cause to be executed and delivered to each Guarantor, all
     such proxies, powers of attorney and other instruments as such Guarantor

     exercise the voting and/or other consensual rights and powers it is
     entitled to exercise pursuant to subparagraph (i) above.

          (iii)  Each Guarantor shall be entitled to receive and retain any and
     all dividends and other distributions paid on or distributed in respect of
     the Pledged Stock pledged by it to the extent and only to the extent that
     such dividends and other distributions are permitted by, and otherwise paid
     or distributed in accordance with, the terms and conditions of the Credit
     Agreement and/or the Loan Agreement, the other Loan Documents and
     applicable laws; PROVIDED that any noncash dividends or other distributions
     that constitute Pledged Stock (whether resulting from a subdivision,
     combination or reclassification of the outstanding Equity Interests of the
     issuer of any Pledged Stock or received in exchange for Pledged Stock or
     any part thereof, or in

                                       -9-
<Page>

     redemption thereof, or as a result of any merger, consolidation,
     acquisition or other exchange of assets to which such issuer may be a party
     or otherwise) shall be and become part of the Collateral, and, if received
     by a Guarantor, shall not be commingled by such Guarantor with any of its
     other funds or property but shall be held separate and apart therefrom,
     shall be held in trust for the benefit of the Bailee (or after the First
     lien Termination Date, the Collateral Agent) and shall be forthwith
     delivered to the Bailee (or after the First Lien Termination Date, the
     Collateral Agent), in the same form as so received (accompanied by stock
     powers duly executed in blank or other appropriate instruments of transfer
     reasonably satisfactory to the Collateral Agent).

          (b)    Upon the occurrence and during the continuance of a Noticed
Event of Default, all rights of the Guarantors to dividends or other
distributions that the Guarantors are authorized to receive pursuant to
paragraph (a)(iii) of this Section 3.06 shall cease, and all such rights shall
thereupon become vested, in (i) prior to the First Lien Termination Date, the
First Lien Collateral Agent and (ii) thereafter, the Collateral Agent, with the
First Lien Collateral Agent (or after the First Lien Termination Date, the
Collateral Agent) having the sole and exclusive right and authority to receive
and retain such dividends or other distributions. All dividends or other
distributions received by a Guarantor contrary to the provisions of this Section
3.06 shall not be commingled by such Guarantor with any of its other funds or
property but shall be held separate and apart therefrom, shall be held in trust
for the benefit of the First Lien Collateral Agent (or after the First Lien
Termination Date, the Collateral Agent, for the ratable benefit of the Second
Lien Secured Parties), and shall be forthwith delivered to the First Lien
Collateral Agent (or after the First Lien Termination Date, the Collateral
Agent, for the ratable benefit of the Second Lien Secured Parties), in the same
form as so received (accompanied by stock powers duly executed in blank or other
appropriate instruments of transfer reasonably satisfactory to the First Lien
Collateral Agent or Collateral Agent, as the case may be). Any and all money and
other property paid over to or received by the First Lien Collateral Agent or
Collateral Agent, as the case may be, pursuant to the provisions of this
paragraph (b) shall be retained by the First Lien Collateral Agent or Collateral
Agent, as the case may be, in an account to be established by the First Lien
Collateral Agent or Collateral Agent, as the case may be, upon receipt of such
money or other property and to the extent received by the Collateral Agent shall
be applied in accordance with the provisions of Section 4.02. On and after the
First Lien Termination Date, once all Noticed Events of Default have been cured
or waived and Holdings has delivered to the Collateral Agent, a certificate to
that effect, the Collateral Agent, to the extent it holds same, shall promptly
repay to the respective Guarantors (without interest) all dividends or other
distributions that each such Guarantor would otherwise have been permitted to
retain pursuant to the terms of paragraph (a)(iii) of this Section 3.05 and that
remain in such account.

          (c)    Upon the occurrence and during the continuance of a Noticed
Event of Default, all rights of the Guarantors to exercise the voting and/or
consensual rights and powers it is entitled to exercise pursuant to paragraph
(a)(i) of this Section 3.05, and the obligations of the Collateral Agent under
paragraph (a)(ii) of this Section 3.05, shall cease, and all such rights shall
thereupon become vested in the First Lien Collateral Agent (or after the First
Lien Termination Date, the Collateral Agent, for the ratable benefit of the
Second Lien Secured Parties), with the First Lien Collateral Agent or Collateral
Agent, as the case may be, having the sole and exclusive right and authority to
exercise such voting and/or consensual rights and powers; PROVIDED that,

                                      -10-
<Page>

after the First Lien Termination Date, unless otherwise directed by the Required
Lenders, the Collateral Agent shall have the right from time to time following
and during the continuance of an Event of Default to permit the Guarantors to
exercise such rights. After all Noticed Events of Default have been cured or
waived and Holdings has delivered to the First Lien Collateral Agent or the
Collateral Agent, as the case may be, a certificate to that effect, the
Guarantors shall have the right to exercise the voting and/or consensual rights
and powers that the Guarantors would otherwise have been entitled to exercise
pursuant to the terms of paragraph (a)(i) above.

                                   ARTICLE IV.

                                    REMEDIES

          SECTION 4.01 REMEDIES UPON DEFAULT. At any time after the occurrence
of the First Lien Termination Date, upon the occurrence and during the
continuance of a Noticed Event of Default, each Guarantor agrees to deliver each
item of Collateral held by it and not in the Collateral Agent's possession to
the Collateral Agent on demand, and it is agreed that the Collateral Agent shall
have the right, subject to the mandatory requirements of applicable law, to sell
or otherwise dispose of all or any part of the Collateral at a public or private
sale or at any broker's board or on any securities exchange, for cash, upon
credit or for future delivery as the Collateral Agent shall deem appropriate.
The Collateral Agent shall be authorized in connection with any sale of a
security (if it deems it advisable to do so) pursuant to the foregoing to
restrict the prospective bidders or purchasers to persons who represent and
agree that they are purchasing such security for their own account, for
investment, and not with a view to the distribution or sale thereof. Upon
consummation of any such sale of Collateral pursuant to this Section 4.01 the
Collateral Agent shall have the right to assign, transfer and deliver to the
purchaser or purchasers thereof the Collateral so sold. Each such purchaser at
any such sale shall hold the property sold absolutely, free from any claim or
right on the part of the Guarantors, and each Guarantor hereby waives and
releases (to the extent permitted by law) all rights of redemption, stay,
valuation and appraisal that such Guarantor now has or may at any time in the
future have under any rule of law or statute now existing or hereafter enacted.

          The Collateral Agent shall give the Guarantors 10 Business Days'
written notice (which the Guarantors agree is reasonable notice within the
meaning of Section 9-612 of the New York UCC or its equivalent in other
jurisdictions) of the Collateral Agent's intention to make any such sale of
Collateral. Such notice, in the case of a public sale, shall state the time and
place for such sale and, in the case of a sale at a broker's board or on a
securities exchange, shall state the board or exchange at which such sale is to
be made and the day on which the Collateral, or portion thereof, will first be
offered for sale at such board or exchange. Any such public sale shall be held
at such time or times within ordinary business hours and at such place or places
as the Collateral Agent may fix and state in the notice (if any) of such sale.
At any such sale, the Collateral, or the portion thereof, to be sold may be sold
in one lot as an entirety or in separate parcels, as the Collateral Agent may
(in its sole and absolute discretion) determine. The Collateral Agent shall not
be obligated to make any sale of any Collateral if it shall determine not to do
so, regardless of the fact that notice of sale of such Collateral shall have
been given. The Collateral Agent may, without notice or publication, adjourn any
public or private sale or cause the same to be adjourned from time to time by
announcement at the time and place fixed for sale, and such sale may, without
further notice, be made at the time and place to which the same was

                                      -11-
<Page>

so adjourned. In the case of any sale of all or any part of the Collateral made
on credit or for future delivery, the Collateral so sold may be retained by the
Collateral Agent until the sale price is paid by the purchaser or purchasers
thereof, but the Collateral Agent shall not incur any liability in the event
that any such purchaser or purchasers shall fail to take up and pay for the
Collateral so sold and, in the case of any such failure, such Collateral may be
sold again upon notice given in accordance with provisions above. At any public
(or, to the extent permitted by law, private) sale made pursuant to this Section
4.01, any Second Lien Secured Party may bid for or purchase for cash, free (to
the extent permitted by law) from any right of redemption, stay, valuation or
appraisal on the part of any Guarantors (all such rights being also hereby
waived and released to the extent permitted by law), the Collateral or any part
thereof offered for sale and such Second Lien Secured Party may, upon compliance
with the terms of sale, hold, retain and dispose of such property in accordance
with Section 4.02 hereof without further accountability to the Guarantors
therefor. For purposes hereof, a written agreement to purchase the Collateral or
any portion thereof shall be treated as a sale thereof; the Collateral Agent
shall be free to carry out such sale pursuant to such agreement and the
Guarantors shall not be entitled to the return of the Collateral or any portion
thereof subject thereto, notwithstanding the fact that after the Collateral
Agent shall have entered into such an agreement all Events of Default shall have
been remedied and the Obligations paid in full. As an alternative to exercising
the power of sale herein conferred upon it, the Collateral Agent may proceed by
a suit or suits at law or in equity to foreclose this Agreement and to sell the
Collateral or any portion thereof pursuant to a judgment or decree of a court or
courts having competent jurisdiction or pursuant to a proceeding by a
court-appointed receiver. Any sale pursuant to the provisions of this Section
4.01 shall be deemed to conform to the commercially reasonable standards as
provided in Section 9-610(b) of the New York UCC or its equivalent in other
jurisdictions. Notwithstanding anything to the contrary in this Agreement, at
law or otherwise, the Collateral Agent and the Second Lien Secured Parties shall
have no rights or remedies under this Section 4.01 prior to the First Lien
Termination Date.

          SECTION 4.02 APPLICATION OF PROCEEDS. The Collateral Agent shall
promptly apply the proceeds, moneys or balances of any collection or sale of
Collateral effected pursuant to Section 4.01, as well as any proceeds, moneys or
balances of all collections or sales of Collateral effected pursuant to the
First Lien Pledge Agreement and paid over to the Collateral Agent pursuant to
Section 4.02 THIRD thereof, or any Collateral consisting of cash and held by the
Collateral Agent, as follows:

          FIRST, to the payment of all costs and expenses incurred by the
     Administrative Agent and the Collateral Agent in connection with such
     collection or sale or otherwise in connection with this Agreement, any
     other Loan Document or any of the Secured Obligations, including all court
     costs and the fees and expenses of its agents and legal counsel, the
     repayment of all advances made by the Administrative Agent and the
     Collateral Agent hereunder or under any other Loan Document on behalf of
     any Guarantor and any other costs or expenses incurred in connection with
     the exercise of any right or remedy hereunder or under any other Loan
     Document;

          SECOND, to the payment in full of the Secured Obligations (the amounts
     so applied to be distributed among the Secured Parties PRO RATA in
     accordance with the

                                      -12-
<Page>

     respective amounts of the Secured Obligations owed to them on the date of
     any such distribution);

          THIRD, to the respective Guarantors, (as their interest may be), their
     successors or assigns, or as a court of competent jurisdiction may
     otherwise direct.

The Collateral Agent shall have absolute discretion as to the time of
application of any such proceeds, moneys or balances in accordance with this
Agreement. Upon any sale of Collateral by the Collateral Agent (including
pursuant to a power of sale granted by statute or under a judicial proceeding),
the receipt of the purchase money by the Collateral Agent or of the officer
making the sale shall be a sufficient discharge to the purchaser or purchasers
of the Collateral so sold and such purchaser or purchasers shall not be
obligated to see to the application of any part of the purchase money paid over
to the Collateral Agent or such officer or be answerable in any way for the
misapplication thereof.

          SECTION 4.03 SECURITIES ACT, ETC. In view of the position of the
Guarantors in relation to the Collateral, or because of other current or future
circumstances, a question may arise under the United States Securities Act of
1933, as now or hereafter in effect, or any similar federal statute hereafter
enacted analogous in purpose or effect (such Act and any such similar statute as
from time to time in effect being called the "FEDERAL SECURITIES LAWS") or other
applicable or regional securities statutes or regulations (together with the
Federal Securities Laws, the "APPLICABLE SECURITIES LAWS") with respect to any
disposition of the Collateral permitted hereunder. The Guarantors understand
that compliance with the Federal Securities Laws might very strictly limit the
course of conduct of the Collateral Agent if the Collateral Agent were to
attempt to dispose of all or any part of the Collateral, and might also limit
the extent to which or the manner in which any subsequent transferee of any
Collateral could dispose of the same. Similarly, there may be other legal
restrictions or limitations affecting the Collateral Agent in any attempt to
dispose of all or part of the Collateral under other state or provincial
securities laws or similar laws analogous in purpose or effect. Each Guarantor
acknowledges and agrees that in light of such restrictions and limitations, the
Collateral Agent, to the extent it then may act under Section 4.01, in its sole
and absolute discretion, (a) may proceed to make such a sale whether or not a
registration statement for the purpose of registering such Collateral or part
thereof shall have been filed under the Applicable Securities Laws or, to the
extent applicable, other state or provincial securities laws and (b) may
approach and negotiate with a single potential purchaser to effect such sale.
Each Guarantor acknowledges and agrees that any such sale might result in prices
and other terms less favorable to the seller than if such sale were a public
sale without such restrictions. In the event of any such sale, the Collateral
Agent shall incur no responsibility or liability for selling all or any part of
the Collateral at a price that the Collateral Agent, in its sole and absolute
discretion, may in good faith deem reasonable under the circumstances,
notwithstanding the possibility that a substantially higher price might have
been realized if the sale were deferred until after registration as aforesaid or
if more than a single purchaser were approached. The provisions of this Section
4.03 will apply notwithstanding the existence of a public or private market upon
which the quotations or sales prices may exceed substantially the price at which
the Collateral Agent sells.

          SECTION 4.04 REGISTRATION, ETC. Each Guarantor agrees that, after the
occurrence of the First Lien Termination Date upon the occurrence and during the
continuance of

                                      -13-
<Page>

an Event of Default, if for any reason the Collateral Agent desires to sell any
of the Collateral at a public sale, it will, at any time and from time to time,
upon the written request of the Collateral Agent, use its commercially
reasonable efforts to take or to cause the issuer of such Collateral to take
such action and prepare, distribute and/or file such documents, as are required
or advisable in the reasonable opinion of counsel for the Collateral Agent to
permit the public sale of such Collateral. Each Guarantor further agrees to
indemnify, defend and hold harmless the Administrative Agent, each other Second
Lien Secured Party, any underwriter and their respective officers, directors,
affiliates and controlling persons from and against all loss, liability,
expenses, costs of counsel (including reasonable fees and expenses of legal
counsel to the Collateral Agent), and claims (including the costs of
investigation) that they may incur insofar as such loss, liability, expense or
claim arises out of or is based upon any alleged untrue statement of a material
fact contained in any prospectus (or any amendment or supplement thereto) or in
any notification or offering circular, or arises out of or is based upon any
alleged omission to state a material fact required to be stated therein or
necessary to make the statements in any thereof not misleading, except insofar
as the same may have been caused by any untrue statement or omission based upon
information furnished in writing to the Guarantor or the issuer of such
Collateral by the Collateral Agent or any other Second Lien Secured Party
expressly for use therein. Each Guarantor further agrees, upon such written
request referred to above, to use its commercially reasonable efforts to
qualify, file or register, or cause the issuer of such Collateral to qualify,
file or register, any of the Collateral under the securities laws of such
regions, nations, states or provinces as may be reasonably requested by the
Collateral Agent and keep effective, or cause to be kept effective, all such
qualifications, filings or registrations. Each Guarantor will bear all costs and
expenses of carrying out its obligations under this Section 4.04. Each Guarantor
acknowledges that there is no adequate remedy at law for failure by it to comply
with the provisions of this Section 4.04 only and that such failure would not be
adequately compensable in damages and, therefore, agrees that its agreements
contained in this Section 4.04 may be specifically enforced.

          SECTION 4.05 LUXEMBOURG LAW PLEDGE. Notwithstanding any other
provisions of this Agreement, so long as any Equity Interests owned by any of
the Guarantors are Equity Interests in a Luxembourg entity, the security
interests in favor of the Collateral Agent for the benefit of the Secured
Parties in such Equity Interests shall be evidenced by, and governed by, an
agreement subject to Luxembourg law (a "Luxembourg Pledge") and the provisions
of such Luxembourg Pledge shall prevail over any provisions hereof relating to
the pledge of such Equity Interests.

                                   ARTICLE V.

                                  SUBORDINATION

          SECTION 5.01 SUBORDINATION. (a) Notwithstanding any provision of this
Agreement to the contrary, all rights of indemnity, contribution or subrogation
of each Guarantor under applicable law or otherwise shall be fully subordinated
to the indefeasible payment in full in cash of the Secured Obligations. No
failure on the part of any Borrower or any Guarantor to make the payments
required under applicable law or otherwise shall in any respect limit the
obligations and liabilities of any Guarantor with respect to its obligations
hereunder, and each Guarantor shall remain liable for the full amount of the
obligations of such Guarantor hereunder.

                                      -14-
<Page>

          (b)    Each Guarantor hereby agrees that all Indebtedness and other
monetary obligations owed by it to any Borrower or any Subsidiary shall be fully
subordinated to the indefeasible payment in full in cash of the Secured
Obligations in the manner provided in Exhibit H to the Credit Agreement.

                                   ARTICLE VI.

                                  MISCELLANEOUS

          SECTION 6.01 NOTICES. All communications and notices hereunder shall
(except as otherwise expressly permitted herein) be in writing and given as
provided in Section 9.01 of the Loan Agreement.

          SECTION 6.02 SECURITY INTEREST ABSOLUTE. All rights of the
Collateral Agent hereunder, the security interest in the Collateral and all
obligations of the Guarantor hereunder shall be absolute and unconditional
irrespective of (a) any lack of validity or enforceability of the Loan
Agreement, any other Loan Document, any agreement with respect to any of the
Obligations or any other agreement or instrument relating to any of the
foregoing, (b) any change in the time, manner or place of payment of, or in any
other term of, all or any of the Secured Obligations, or any other amendment or
waiver of or any consent to any departure from the Loan Agreement, any other
Loan Document, or any other agreement or instrument, (c) any exchange, release
or non-perfection of any Lien on other collateral, or any release or amendment
or waiver of or consent under or departure from any guarantee, securing or
guaranteeing all or any of the Secured Obligations or (d) any other circumstance
that might otherwise constitute a defense available to, or a discharge of, any
Guarantor in respect of the Secured Obligations or this Agreement.

          SECTION 6.03 SUBORDINATED SECURITY INTERESTS. The security interests
of the Second Lien Secured Parties in the Collateral are hereby, and shall
continue to be, subject , junior and subordinated in all respects to the
security interests of the First Lien Secured Parties in the Collateral in each
case to the extent, and in the manner, set forth herein. The foregoing shall
apply notwithstanding (i) the actual date and time of execution, delivery,
recordation, filing or perfection of any security interests granted with respect
to the First Lien Secured Obligations, or the lien (whether perfected or
unperfected) thereof, and (ii) any instance wherein the First Lien Secured
Obligations or any claim for the First Lien Secured Obligations is subordinated,
avoided or disallowed, in whole or in part, under Title II of the United States
Code or other applicable federal or state law. The Collateral Agent and the
Second Lien Secured Parties shall have no rights to enforce or realize upon any
Collateral except as expressly set forth herein and hereby waive any right of
enforcement or realization they might otherwise have at law or otherwise..

          SECTION 6.04 BINDING EFFECT; SEVERAL AGREEMENT. This Agreement shall
become effective as to any party to this Agreement when a counterpart hereof
executed on behalf of such party shall have been delivered to the Collateral
Agent and a counterpart hereof shall have been executed on behalf of the
Collateral Agent, and, in each case, thereafter shall be binding upon such party
and the Collateral Agent and their respective permitted successors and assigns,
and shall inure to the benefit of such party, the Collateral Agent and the other
Second Lien Secured Parties and their respective permitted successors and
assigns, except that no party

                                      -15-
<Page>

shall have the right to assign or transfer its rights or obligations hereunder
or any interest herein or in the Collateral (and any such assignment or transfer
shall be void) except as expressly contemplated by this Agreement or the Credit
Agreement. This Agreement shall be construed as a separate agreement with
respect to each party and may be amended, modified, supplemented, waived or
released with respect to any party without the approval of any other party and
without affecting the obligations of any other party hereunder. Notwithstanding
the forgoing, Article III, Article IV, Section 6.02 and Section 6.03 of this
Agreement shall only be effective on and after the Restructuring Date.

          SECTION 6.05 SUCCESSORS AND ASSIGNS. Whenever in this Agreement any
of the parties hereto is referred to, such reference shall be deemed to include
the permitted successors and assigns of such party; and all covenants, promises
and agreements by or on behalf of any Guarantor or the Collateral Agent that are
contained in this Agreement shall bind and inure to the benefit of their
respective permitted successors and assigns.

          SECTION 6.06 COLLATERAL AGENT'S FEES AND EXPENSES; INDEMNIFICATION.
(a) The parties hereto agree that the Collateral Agent shall be entitled to
reimbursement of its expenses incurred hereunder as provided in Section 9.05 of
the Loan Agreement.

          (b)    Without limitation of its indemnification obligations under the
other Loan Documents, each Guarantor agrees to indemnify the Collateral Agent
and the other Indemnitees (as defined in Section 9.05 of the Loan Agreement)
against, and hold each Indemnitee harmless from, any and all losses, claims,
damages, liabilities and related expenses, including reasonable counsel fees,
charges and disbursements, incurred by or asserted against any Indemnitee
arising out of, in connection with, or as a result of, (i) the execution,
delivery or performance of this Agreement or any other Loan Document or any
agreement or instrument contemplated hereby or thereby, the performance by the
parties hereto and thereto of their respective obligations thereunder or the
consummation of the Transaction and other transactions contemplated hereby, (ii)
the use of proceeds of the Loans or the use of any Letter of Credit or (iii) any
claim, litigation, investigation or proceeding relating to any of the foregoing,
or to the Collateral, whether or not any Indemnitee is a party thereto; PROVIDED
that such indemnity shall not, as to any Indemnitee, be available to the extent
that such losses, claims, damages, liabilities or related expenses result
primarily from the gross negligence or willful misconduct of such Indemnitee
(treating for the purposes of this Section 6.06(b) only, any Second Lien Secured
Party and its Related Parties as a single Indemnitee).

          (c)    Any such amounts payable as provided hereunder shall be
additional Secured Obligations hereunder. The provisions of this Section 6.06
shall remain operative and in full force and effect regardless of the
termination of this Agreement or any other Loan Document, the consummation of
the transactions contemplated hereby, the repayment of any of the Secured
Obligations, the invalidity or unenforceability of any term or provision of this
Agreement or any other Loan Document, or any investigation made by or on behalf
of the Collateral Agent or any other Second Lien Secured Party. All amounts due
under this Section 6.06 shall be payable on written demand therefor (accompanied
by a reasonably detailed computation of the amounts so to be paid).

                                      -16-
<Page>

          SECTION 6.07 COLLATERAL AGENT APPOINTED ATTORNEY-IN-FACT. By way of
securing its obligations hereunder, each Guarantor hereby appoints the
Collateral Agent the attorney-in-fact of such Guarantor for the purpose, if the
First Lien Termination Date has occurred, during the continuance of an Event of
Default, of carrying out the provisions of this Agreement and taking any action
and executing any instrument that the Collateral Agent may deem necessary or
advisable to accomplish the purposes hereof, which appointment is irrevocable
and coupled with an interest. Without limiting the generality of the foregoing,
if and only if the First Lien Termination Date has occurred, the Collateral
Agent shall have the right, upon the occurrence and during the continuance of a
Noticed Event of Default, with full power of substitution either in the
Collateral Agent's name or in the name of a Guarantor, (a) to receive, endorse,
assign or deliver any and all notes, acceptances, checks, drafts, money orders
or other evidences of payment relating to the Collateral or any part thereof;
(b) to demand, collect, receive payment of, give receipt for and give discharges
and releases of all or any of the Collateral; (c) to ask for, demand, sue for,
collect, receive and give acquittance for any and all moneys due or to become
due under and by virtue of any Collateral; (d) to commence and prosecute any and
all suits, actions or proceedings at law or in equity in any court of competent
jurisdiction to collect or otherwise realize on all or any of the Collateral or
to enforce any rights in respect of any Collateral; (e) to settle, compromise,
compound, adjust or defend any actions, suits or proceedings relating to all or
any of the Collateral; and (f) to use, sell, assign, transfer, pledge, make any
agreement with respect to or otherwise deal with all or any of the Collateral,
and to do all other acts and things necessary to carry out the purposes of this
Agreement, as fully and completely as though the Collateral Agent were the
absolute owner of the Collateral for all purposes; PROVIDED that nothing herein
contained shall be construed as requiring or obligating the Collateral Agent to
make any commitment or to make any inquiry as to the nature or sufficiency of
any payment received by the Collateral Agent, or to present or file any claim or
notice, or to take any action with respect to the Collateral or any part thereof
or the moneys due or to become due in respect thereof or any property covered
thereby. The Collateral Agent and the other Second Lien Secured Parties shall be
accountable only for amounts actually received as a result of the exercise of
the powers granted to them herein, and neither they nor their officers,
directors, employees or agents shall be responsible to the Guarantor for any act
or failure to act hereunder, except for their own gross negligence or willful
misconduct.

          SECTION 6.08 [RESERVED].

          SECTION 6.09 GOVERNING LAW. THIS AGREEMENT AND THE RIGHTS AND
OBLIGATIONS OF THE PARTIES UNDER THIS AGREEMENT SHALL BE CONSTRUED IN ACCORDANCE
WITH AND GOVERNED BY THE LAWS OF THE STATE OF NEW YORK.

          SECTION 6.10 WAIVERS; AMENDMENT. (a) No failure or delay by any
Second Lien Secured Party in exercising any right, power or remedy hereunder or
under any other Loan Document shall operate as a waiver thereof, nor shall any
single or partial exercise of any such right, power or remedy, or any
abandonment or discontinuance of steps to enforce such a right, power or remedy,
preclude any other or further exercise thereof or the exercise of any other
right, power or remedy. The rights, powers and remedies of the Second Lien
Secured Parties hereunder and under the other Loan Documents are cumulative and
are not exclusive of any rights, powers or remedies that they would otherwise
have. No waiver of any provision of this

                                      -17-
<Page>

Agreement or consent to any departure by any Loan Party therefrom shall in any
event be effective unless the same shall be permitted by paragraph (b) of this
Section 6.10, and then such waiver or consent shall be effective only in the
specific instance and for the purpose for which given. Without limiting the
generality of the foregoing, the making of a Loan shall not be construed as a
waiver of any Default or Event of Default, regardless of whether any Second Lien
Secured Party may have had notice or knowledge of such Default or Event of
Default at the time. No notice or demand on any Loan Party in any case shall
entitle any Loan Party to any other or further notice or demand in similar or
other circumstances.

          (b)    Neither this Agreement nor any provision hereof may be waived,
amended or modified except pursuant to an agreement or agreements in writing
entered into by the Collateral Agent and the Guarantor or Guarantors effected
thereby, subject to any consent required in accordance with Section 9.08 of the
Loan Agreement.

          (c)    Notwithstanding anything to the contrary contained in Section
6.10, any amendment, waiver or modification of any of the provisions of the
First Lien Pledge Agreement relating to the granting, maintenance or enforcement
of Liens shall constitute an amendment, waiver or modification of the respective
provision of this Agreement without the consent of the Collateral Agent, any
Loan Party or any Second Lien Secured Party; PROVIDED that any amendment, waiver
or modification the effect of which would eliminate or terminate the Liens
granted to the Second Lien Secured Parties pursuant to this Agreement shall not
be effective without the agreement in writing of the Collateral Agent and the
Loan Parties as provided in Section 6.10(b) above.

          SECTION 6.11 WAIVER OF JURY TRIAL. EACH PARTY HERETO HEREBY WAIVES, TO
THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL
BY JURY IN RESPECT OF ANY LITIGATION DIRECTLY OR INDIRECTLY ARISING OUT OF,
UNDER OR IN CONNECTION WITH THIS AGREEMENT OR ANY OTHER LOAN DOCUMENTS. EACH
PARTY HERETO (A) CERTIFIES THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY
OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD
NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER AND (B)
ACKNOWLEDGES THAT IT AND THE OTHER PARTIES HERETO HAVE BEEN INDUCED TO ENTER
INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND
CERTIFICATIONS IN THIS SECTION 6.10.

          SECTION 6.12 SEVERABILITY. In the event any one or more of the
provisions contained in this Agreement or in any other Loan Document should be
held invalid, illegal or unenforceable in any respect, the validity, legality
and enforceability of the remaining provisions contained herein and therein
shall not in any way be affected or impaired thereby. The parties shall endeavor
in good-faith negotiations to replace the invalid, illegal or unenforceable
provisions with valid provisions the economic effect of which comes as close as
possible to that of the invalid, illegal or unenforceable provisions.

          SECTION 6.13 COUNTERPARTS. This Agreement may be executed in two or
more counterparts, each of which shall constitute an original but all of which
when taken together shall

                                      -18-
<Page>

constitute but one contract, and shall become effective as provided in Section
6.04. Delivery of an executed counterpart to this Agreement by facsimile
transmission shall be as effective as delivery of a manually signed original.

          SECTION 6.14 HEADINGS. Article and Section headings and the Table of
Contents used herein are for convenience of reference only, are not part of this
Agreement and are not to affect the construction of, or to be taken into
consideration in interpreting, this Agreement.

          SECTION 6.15 JURISDICTION; CONSENT TO SERVICE OF PROCESS. (a) Each
party to this Agreement hereby irrevocably and unconditionally submits, for
itself and its property, to the nonexclusive jurisdiction of any New York State
court or federal court of the United States of America sitting in New York City,
and any appellate court from any thereof, in any action or proceeding arising
out of or relating to this Agreement or any other Loan Documents, or for
recognition or enforcement of any judgment, and each of the parties hereto
hereby irrevocably and unconditionally agrees that all claims in respect of any
such action or proceeding may be heard and determined in such New York State or,
to the extent permitted by law, in such federal court. Each of the parties
hereto agrees that a final judgment in any such action or proceeding shall be
conclusive and may be enforced in other jurisdictions by suit on the judgment or
in any other manner provided by law. Nothing in this Agreement shall affect any
right that the Administrative Agent, the Collateral Agent or any Lender may
otherwise have to bring any action or proceeding relating to this Agreement or
any other Loan Document against the Guarantor, or its properties, in the courts
of any jurisdiction.

          (b)    Each party to this Agreement hereby irrevocably and
unconditionally waives, to the fullest extent it may legally and effectively do
so, any objection which it may now or hereafter have to the laying of venue of
any suit, action or proceeding arising out of or relating to this Agreement or
any other Loan Document in any New York State or federal court. Each of the
parties hereto hereby irrevocably waives, to the fullest extent permitted by
law, the defense of an inconvenient forum to the maintenance of such action or
proceeding in any such court.

          (c)    Each Guarantor not a party to the Credit Agreement hereby
appoints BCP Crystal US Holdings Corp. at 345 Park Avenue, New York, NY as its
agent for service of process, such appointment to be on the same basis as set
forth in Section 9.15(c) of the Credit Agreement.

          SECTION 6.16 TERMINATION. (a) This Agreement, the guarantees made
herein and, the security interests granted hereby shall terminate when all the
Loan Document Obligations have been indefeasibly paid in full in cash.

          (b)    BCP Ltd.1 and/or Cayman 1 shall automatically be released from
its obligations hereunder and the security interests in the Collateral of such
Person shall be automatically released upon the consummation of any transaction
permitted by the Credit Agreement as a result of which such Person ceases to be
a Subsidiary of Holdings, PROVIDED that the Required Lenders shall have
consented to such transaction (to the extent such consent is required by the
Loan Agreement) and the terms of such consent did not provide otherwise.

                                      -19-
<Page>

          (c)    Upon any sale or other transfer by any Guarantor of any
Collateral that is permitted under the Credit Agreement to any Person that is
not a Guarantor or Domestic Loan Party, or upon the effectiveness of any written
consent to the release of the security interest granted hereby in any Collateral
pursuant to Section 9.08 of the Loan Agreement, the security interest in such
Collateral shall be automatically released.

          (d)    In connection with any termination or release pursuant to
paragraph (a), (b) or (c) of this Section 6.16, the Collateral Agent shall
execute and deliver to the Guarantors, at the Guarantors' expense, all documents
that Holdings shall reasonably request to evidence such termination or release.
Any execution and delivery of documents pursuant to this Section 6.16 shall be
without recourse to or warranty by the Collateral Agent.
