          SECTION 2.01 GUARANTEE. Each Guarantor unconditionally guarantees,
jointly with the other Guarantors and severally, as a primary obligor and not
merely as a surety, the due and punctual payment and performance of its
Guaranteed Obligations. Each Guarantor further agrees that its Guaranteed
Obligations may be extended or renewed, in whole or in part, without notice to
or further assent from it, and that it will remain bound upon its guarantee
notwithstanding any extension or renewal of any of its Guaranteed Obligations.
Each Guarantor waives presentment to, demand of payment from and protest to any
Borrower of any of its Guaranteed Obligations, and also waives notice of
acceptance of its guarantee and notice of protest for nonpayment.

          SECTION 2.02 GUARANTEE OF PAYMENT. Each Guarantor further agrees that
its guarantee hereunder constitutes a guarantee of payment when due and not of
collection, and waives any right to require that any resort be had by the
Collateral Agent or any other Secured Party to any security held for the payment
of its Guaranteed Obligations or to any balance of any deposit account or credit
on the books of the Collateral Agent or any other Secured Party in favor of any
Borrower or any other person.

          SECTION 2.03 NO LIMITATIONS, ETC. (a) Except for termination of such
Guarantor's obligations hereunder as expressly provided for in Section 6.16, the
obligations of each Guarantor hereunder shall not be subject to any reduction,
limitation, impairment or termination for any reason, including any claim of
waiver, release, surrender, alteration or compromise, and shall not be subject
to any defense or setoff, counterclaim, recoupment or termination whatsoever by
reason of the invalidity, illegality or unenforceability of its Guaranteed
Obligations or otherwise. Without limiting the generality of the foregoing, the
obligations of none of the Guarantors hereunder shall be discharged or impaired
or otherwise affected by:

                                       -3-
<Page>

          (i)     the failure of the Administrative Agent, the Collateral Agent
     or any other Secured Party to assert any claim or demand or to exercise or
     enforce any right or remedy under the provisions of any Loan Document or
     otherwise;

          (ii)    any rescission, waiver, amendment or modification of, or any
     release from any of the terms or provisions of, any Loan Document or any
     other agreement (including with respect to any other Guarantor hereunder);

          (iii)   the failure to perfect any security interest in, or the

     performance of the Secured Obligations;

          (v)     any other act or omission that may or might in any manner or
     to any extent vary the risk of any Guarantor or otherwise operate as a
     discharge of any Guarantor as a matter of law or equity (other than the
     indefeasible payment in full in cash of all the Secured Obligations);

          (vi)    any illegality, lack of validity or enforceability of any
     Secured Obligation;

          (vii)   any change in the corporate existence, structure or ownership
     of any Borrower, or any insolvency, bankruptcy, reorganization or other
     similar proceeding affecting any Borrower or its assets or any resulting
     release or discharge of any Secured Obligation;

          (viii)  the existence of any claim, set-off or other rights that any
     Guarantor may have at any time against any Borrower, the Collateral Agent,
     or any other corporation or person, whether in connection herewith or any
     unrelated transactions, provided that nothing herein will prevent the
     assertion of any such claim by separate suit or compulsory counterclaim;

          (ix)    any law, regulation, decree or order of any jurisdiction, or
     any other event, affecting any term of any of its Guaranteed Obligations or
     the Collateral Agent's rights with respect thereto, including, without
     limitation:

                  (A)  the application of any such law, regulation, decree or
          order, including any prior approval, which would prevent the exchange
          of a foreign currency for Dollars or any other currency in which any
          of the Guaranteed Obligations is to be paid or the remittance of funds
          outside of such jurisdiction or the unavailability of Dollars or such
          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, each Guarantor hereby
assigns and pledges to the Collateral Agent, its successors and assigns, for the
ratable benefit of the Secured Parties, and hereby grants to the Collateral
Agent, its successors and assigns, for the ratable benefit of the 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 (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)

                                       -6-
<Page>

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
of the Secured Parties, forever; SUBJECT, HOWEVER, to the terms, covenants and
conditions hereinafter set forth.

          SECTION 3.02 DELIVERY OF THE COLLATERAL. (a) Each Guarantor agrees
promptly to deliver or cause to be delivered to the Collateral Agent, for the
ratable benefit of the Secured Parties, any and all Pledged Stock owned by it.

          (b)     Upon delivery to the Collateral Agent, (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 Collateral Agent and by
such other instruments and documents as the Collateral Agent 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 Collateral Agent 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 Secured Parties, that:

     and outstanding shares of each class of the Equity Interests of the issuer

     other than pursuant to a transaction permitted by the Credit Agreement and
     other than 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 Loan
     Documents, or securities laws generally or otherwise permitted to exist
     pursuant to the terms of the Credit 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
     contemplated;

          (f)     no consent or approval of any Governmental Authority, any
     securities exchange or any other person was or is necessary to the validity
     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, when any Pledged Stock is delivered to the Collateral
     Agent, for the benefit of the Secured Parties, in accordance with this
     Agreement, the Collateral Agent will obtain, for the benefit of the Secured
     Parties, a legal, valid and perfected first 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 benefit of the 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 Secured Parties, shall have the right (in its
sole and absolute discretion) 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.

                                       -8-

          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 and the other 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 Collateral Agent or the other Secured Parties under
     this Agreement, the Credit Agreement or any other Loan Document or the
     ability of the 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 may reasonably request for the purpose of enabling such Guarantor
     to 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 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 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 ratable
     benefit of the Collateral Agent, for the ratable benefit of the Secured
     Parties, and shall be forthwith delivered to the Collateral Agent, for the
     ratable benefit of the 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 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, for the ratable benefit of the Secured Parties, in the
Collateral Agent which shall have 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 Collateral Agent, for the ratable benefit of the Secured
Parties, and shall be forthwith delivered to the Collateral Agent, for the
ratable benefit of the

                                       -9-
<Page>

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 Collateral Agent). Any and all money and other property paid
over to or received by the Collateral Agent pursuant to the provisions of this
paragraph (b) shall be retained by the Collateral Agent in an account to be
established by the Collateral Agent upon receipt of such money or other property
and shall be applied in accordance with the provisions of Section 4.02. After
all Events of Default have been cured or waived and Holdings has delivered to
the Collateral Agent a certificate to that effect, the Collateral Agent 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 Collateral Agent, for the ratable benefit of the
Secured Parties, which shall have the sole and exclusive right and authority to
exercise such voting and/or consensual rights and powers; PROVIDED that, 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
Collateral Agent 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. 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

                                      -10-
<Page>

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 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 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 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 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.

          SECTION 4.02 APPLICATION OF PROCEEDS. The Collateral Agent shall
promptly apply the proceeds, moneys or balances of any collection or sale of
Collateral, as well as any Collateral consisting of cash, as follows:

                                      -11-
<Page>

          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 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, 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

                                      -12-
<Page>

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, upon the
occurrence and during the continuance of 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 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
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 the
Guarantor 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.

                                      -13-

                                   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.

          (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 Credit 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 Credit 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 Credit 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 [RESERVED].

          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 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
Secured Parties and their

                                      -14-
<Page>

respective permitted successors and assigns, except that no party 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.

          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 Credit 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 Credit
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 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 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).

          SECTION 6.07 COLLATERAL AGENT APPOINTED ATTORNEY-IN-FACT. By way of
securing its obligations hereunder, each Guarantor hereby appoints the
Collateral Agent the

                                      -15-
<Page>

attorney-in-fact of such Guarantor for the purpose, 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, 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 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
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 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 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

                                      -16-
<Page>

generality of the foregoing, the making of a Loan or the issuance of a Letter of
Credit shall not be construed as a waiver of any Default or Event of Default,
regardless of whether any 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
Credit Agreement.

          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 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

                                      -17-
<Page>

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, any
Issuing Bank 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 and the
Lenders have no further commitment to lend under the Credit Agreement, the
Revolving L/C Exposure and CL Exposure have been reduced to zero and each
Issuing Bank has no further obligations to issue Letters of Credit under the
Credit Agreement.

          (b)     BCP Ltd.1 and/or Cayman I 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
Credit Agreement) and the terms of such consent did not provide otherwise.

          (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 Credit 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

                                      -18-
<Page>

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.

          SECTION 6.17 RIGHT OF SET-OFF. If an Event of Default shall have
occurred and be continuing, each Lender is hereby authorized at any time and
from time to time, to the fullest extent permitted by law, to set-off and apply
any and all deposits (general or special, time or demand, provisional or final)
at any time held and other indebtedness at any time owing by such Lender to or
for the credit or the account of any party to this Agreement against any of and
all the obligations of such party now or hereafter existing under this Agreement
owed to such Lender, irrespective of whether or not such Lender shall have made
any demand under this Agreement and although such obligations may be unmatured.
The rights of each Lender under this Section 6.17 are in addition to other
rights and remedies (including other rights of set-off) that such Lender may
have.
