                           for, any or all of the Collateral, and without

                           provision of the Credit Agreement, in the event of
                           any consolidation or merger in which such Pledgor is
                           not the surviving corporation, all shares of each
                           class or Capital Stock of the successor entity formed
                           by or resulting from such consolidation or merger

                           the "Collateral Proceeds");

a "controlled foreign corporation" (within the meaning of the Internal Revenue
Code) representing more than sixty-five percent (65%) of the combined voting
power of all classes of stock or membership interests entitled to vote (the
"Voting Stock") of any such entity.

         Without limiting the generality of the foregoing, it is hereby
specifically understood and agreed that a Pledgor may from time to time
hereafter deliver additional Capital Stock to the Administrative Agent as
collateral security for the Secured Obligations. Upon delivery to the
Administrative Agent, such additional Capital Stock shall be deemed to be part
of the Collateral of such Pledgor and shall be subject to the terms of this
Pledge Agreement whether or not Schedule 2.1(a) is amended to refer to such
additional Capital Stock.

         2.2      Secured Obligations. The Collateral shall secure (subject to
Section 7.14 hereof) the following obligations, indebtedness and liabilities,
without duplication (all such obligations, indebtedness and liabilities being
hereinafter sometimes called the "Secured Obligations"):

         (a)      all of the obligations of the Loan Parties to the Lenders
                  (including the L/C Issuer, the Credit-Linked L/C Issuer and
                  the Swing Line Lender) and the Administrative Agent under the
                  Credit Agreement and the other Loan Documents (including, but
                  not limited to, any interest accruing after the commencement
                  by or against any Loan Party of a proceeding under any

                                       2
<PAGE>

                  Debtor Relief Laws, regardless of whether such interest is an
                  allowed claim under such proceeding), whether now existing or
                  hereafter arising, due or to become due, direct or indirect,
                  absolute or contingent, howsoever evidenced, created, held or
                  acquired, whether primary, secondary, direct, contingent, or
                  joint and several, as such obligations may be amended,
                  modified, increased, extended, renewed or replaced from time
                  to time;

         (b)      all of the obligations owing by the Loan Parties under any
                  Swap Contract with any Lender or any Affiliate of a Lender,
                  whether now existing or hereafter arising;

         (c)      all indemnity obligations of the Loan Parties under the Credit
                  Agreement; and

         (d)      all costs and expenses incurred in connection with enforcement
                  and collection of the foregoing obligations, including
                  reasonable attorneys' fees.

         2.3      Delivery of the Collateral. Each Pledgor hereby agrees that:

         (a)      Delivery of Certificates. Each Pledgor shall deliver to the
                  Administrative Agent (i) simultaneously with or prior to the
                  execution and delivery of this Pledge Agreement, all
                  certificates representing the Pledged Shares of such Pledgor
                  and (ii) promptly upon the receipt thereof by or on behalf of
                  a Pledgor, all other certificates and instruments constituting
                  Collateral of a Pledgor. Prior to such delivery to the
                  Administrative Agent, all such certificates and instruments
                  constituting Collateral of a Pledgor shall be held in trust by
                  such Pledgor for the benefit of the Administrative Agent
                  pursuant hereto. All such certificates shall be delivered in
                  suitable form for transfer by delivery or shall be accompanied
                  by duly executed instruments of transfer or assignment in
                  blank, substantially in the form provided in Schedule 2.3(a)
                  attached hereto.

         (b)      Financing Statements. Each Pledgor authorizes the
                  Administrative Agent to file one or more financing statements
                  (with collateral descriptions broader, including without
                  limitation "all assets" and/or "all personal property"
                  collateral descriptions, and/or less specific than the
                  description of the Collateral contained herein) disclosing the
                  Administrative Agent's security interest in the Collateral.
                  Each Pledgor agrees to execute and deliver to the
                  Administrative Agent such financing statements and other
                  filings as may be reasonably requested by the Administrative
                  Agent in order to perfect and protect the security interest
                  created hereby in the Collateral of such Pledgor.

SECTION 3. REPRESENTATIONS AND WARRANTIES. Each Pledgor represents and warrants
to the Administrative Agent for the benefit of the holders of the Secured
Obligations, that so long as any of the Secured Obligations remain outstanding
and until all of the commitments relating thereto have been terminated:

         3.1      Title. Such Pledgor owns or, with respect to Collateral
acquired after the date hereof, such Pledgor will own, legally and beneficially,
the Collateral free and clear of any Lien, security interest, pledge, claim, or
other encumbrance or any right or option on the part of any third person to
purchase or otherwise acquire the Collateral or any part thereof, except for the
security interest granted hereunder and Permitted Liens. Such Pledgor has the
unrestricted right to pledge the Collateral as contemplated hereby, and there
exists no "adverse claim" within the meaning of Section 8-102 of the UCC with
respect to the Collateral.

         3.2      Organization and Authority. Neither the execution, delivery or
performance by such Pledgor of this Agreement nor compliance by it with the
terms and provisions hereof, nor the

                                       3
<PAGE>

consummation of the transactions contemplated herein, will (i) contravene any
applicable provision of any law, statute, rule or regulation, or any order,
writ, injunction or decree of any court or governmental instrumentality; or (ii)
conflict with or result in any breach of any term, covenant, condition or other
provision of, or constitute a default under, or (other than pursuant to the
Collateral Documents) result in the creation or imposition of (or the obligation
to create or impose) any Lien upon any of the property or assets of such Pledgor
under the terms of any contractual obligation to which such Pledgor is a party
or by which it or any of its properties or assets are bound or to which it may
be subject.

         3.3      First Priority Perfected Security Interest. This Agreement has
been duly authorized, executed and delivered by such Pledgor. This Agreement
creates a valid security interest in favor of the Administrative Agent for the
benefit of the Lenders in the Collateral. The taking of possession by the
Administrative Agent of the certificates representing the Pledged Shares and all
other certificates and instruments constituting Collateral will perfect and
establish the first priority of the Administrative Agent's security interest in
the Pledged Shares consisting of certificated securities and, when properly
perfected by filing or registration, in all other Collateral represented by such
Pledged Shares and instruments securing the Secured Obligations. Except as set
forth in this Section 3.3 and except as may be required by applicable foreign
laws affecting the pledge of Capital Stock of Foreign Subsidiaries, no action is
necessary to perfect or otherwise protect such security interest.

         3.4      Partnership and Membership Interests. Except as previously
disclosed to the Administrative Agent, none of the Pledged Shares consisting of
partnership or limited liability company interests (i) is dealt in or traded on
a securities exchange or in a securities market, (ii) by its terms expressly
provides that it is a security governed by Article 8 of the UCC, (iii) is an
investment company security, (iv) is held in a securities account or (v)
constitutes a Security or a Financial Asset (as each is defined in the UCC).

         3.5      No Consent. No consent of, or notice to, any other Person and
no authorization, approval or other action by, and no notice to or filing with,
any governmental authority or regulatory body is required for the grant by such
Pledgor of the Liens granted hereby or for the execution, delivery or
performance of this Agreement by such Pledgor, other than the filing of
financing statements and the filing of an investment act notice in connection
with the stock of any Company organized in Canada and except for such other
consents, notices or filings that have been obtained or made or that as of the
date hereof are not required to have been obtained or made and may be obtained
or made, as the case may be, when necessary.

SECTION 4. COVENANTS. Each Pledgor covenants and agrees that so long as any of
the Secured Obligations remain outstanding and until all of the commitments
relating thereto have been terminated such Pledgor shall:

         4.1      Encumbrances. Except as permitted by the Credit Agreement,
each Pledgor shall not create, permit, or suffer to exist, and shall defend the
Collateral against, any Lien on the Collateral except the pledge and security
interest of the Administrative Agent hereunder and except for Permitted Liens,
and shall warrant and defend title to and ownership of the Collateral of such
Pledgor at its own expense against the claims and demands of all other parties
claiming an interest therein and defend such Pledgor's rights in the Collateral
and the Administrative Agent's security interest in the Collateral against the
claims of all persons and entities (other than any person or entity claiming by,
through or under the Administrative Agent or any obligee of the Secured
Obligations).

         4.2      Sale of Collateral. No Pledgor shall sell, assign, or
otherwise dispose of the Collateral or any part thereof except as permitted by
the Credit Agreement.

                                       4
<PAGE>

         4.3      Dividends. If any Pledgor shall become entitled to receive or
shall receive any distribution (including, without limitation, any dividend or
distribution in connection with any reclassification, increase, or reduction of
capital or issued in connection with any reorganization), option or rights
constituting Collateral, whether as an addition to, in substitution of, or in
exchange for any Collateral or otherwise, such Pledgor agrees to accept the same
as the Administrative Agent's agent and to hold the same in trust for the
Administrative Agent and to deliver the same (to the extent in form capable of
delivery) promptly to the Administrative Agent in the exact form received, with
the appropriate endorsement of such Pledgor when necessary, to be held by the
Administrative Agent, as additional Collateral for the Secured Obligations,
subject to the terms hereof. Any sums paid upon or in respect of the Collateral
upon the liquidation or dissolution of the issuer thereof in violation of the
Credit Agreement shall be paid over to the Administrative Agent to be held by it
as additional Collateral for the Secured Obligations subject to the terms hereof
except as otherwise provided in the Credit Agreement; and in case any
distribution shall be made on or in respect of the Collateral while a Default or
an Event of Default shall be continuing or any property shall be distributed
while a Default or an Event of Default shall be continuing upon or with respect
to the Collateral pursuant to any recapitalization or reclassification of the
capital of the issuer thereof or pursuant to any reorganization of the issuer
thereof, the property so distributed shall be delivered to the Administrative
Agent to be held by it, as additional Collateral for the Secured Obligations,
subject to the terms hereof. All sums of money and property so paid or
distributed in respect of the Collateral that are received by such Pledgor
shall, until paid or delivered to the Administrative Agent, be held by such
Pledgor in trust as additional security for the Secured Obligations, provided
that except to the extent that such sums of money or property have theretofore
been applied against the Secured Obligations in accordance with the Credit
Agreement, such sums of money or property shall forthwith be delivered to such
Pledgor at such time as no Default or Event of Default shall be continuing under
the Credit Agreement.

         4.4      Further Assurances. At any time and from time to time, upon
the request of the Administrative Agent, and at the sole expense of such
Pledgor, such Pledgor shall promptly execute and deliver all such further
instruments and documents and take such further action as the Administrative
Agent may deem reasonably necessary or desirable to (a) preserve and perfect its
security interest in the Collateral; (b) enable the Administrative Agent to
exercise and enforce its rights and remedies hereunder in respect of the
Collateral of such Pledgor; and (c) carry out the provisions and purposes of
this Agreement, including, without limitation, (i) the execution and filing of
such financing statements as the Administrative Agent may require and (ii) upon
the occurrence and during the continuance of an Event of Default, if requested
by the Administrative Agent, delivering to the Administrative Agent irrevocable
proxies in respect of the Collateral of such Pledgor.

         4.5      Inspection Rights. Upon reasonable notice from the
Administrative Agent, each Pledgor shall permit the Administrative Agent and its
representatives to examine, inspect, and copy such Pledgor's books and records
concerning ownership of the Collateral at any reasonable time during normal
business hours and as often as the Administrative Agent may desire.

         4.6      Books and Records. Each Pledgor shall mark its books and
records (and shall cause the issuer of the Pledged Shares to mark its books and
records) to reflect the security interest of the Administrative Agent for the
benefit of the holders of the Secured Obligations under this Agreement.

         4.7      Receipt after Default. If any Collateral is received by any
Pledgor during the continuance of an Event of Default, Pledgor shall pay over to
the Administrative Agent all such Collateral on the day received, including the
cash and checks endorsed by such Pledgor evidencing the Collateral. Such Pledgor
shall not commingle the Collateral with any other funds, proceeds or monies of
such Pledgor, and

                                       5
<PAGE>

shall keep such proceeds separate and apart from any other funds, proceeds or
monies of such Pledgor and shall hold the Collateral in trust for the
Administrative Agent until same shall be paid over to the Administrative Agent
as agreed to herein.

         4.8      Pledge of Shares of Controlled Foreign Corporation.

         (a)      In the event that the Collateral hereunder would, but for this
                  Section 4.8(a), represent more than sixty-five percent (65%)
                  of the Voting Stock of a Company which is a controlled foreign
                  corporation, then the number of shares of Voting Stock of such
                  Company in excess of such sixty-five percent (65%)
                  automatically shall be released from the Lien of, and the
                  terms and provisions of, this Agreement.

         (b)      In the event that the Collateral hereunder represents less
                  than sixty-five percent (65%) of the Voting Stock of any
                  Company which is a controlled foreign corporation (or, if
                  less, 100% of the Voting Stock of such Company owned by
                  Pledgor), then such Pledgor will promptly pledge additional
                  capital stock to increase the number of shares pledged
                  hereunder to such sixty-five percent (65%) (or, if less, 100%
                  of the Voting Stock of such Company owned by such Pledgor).

         4.9      Amendments. Not make or consent to any amendment or other
modification or waiver with respect to any of the Collateral of such Pledgor or
enter into any agreement or allow to exist any restriction with respect to any
of the Collateral of such Pledgor that is prohibited under the Credit Agreement
or any other Loan Document.

         4.10     Compliance with Securities Laws. File all reports and other
information now or hereafter required to be filed by such Pledgor with the
United States Securities and Exchange Commission and any other state, federal or
foreign agency in connection with such Pledgor's ownership of the Collateral of
such Pledgor.

         4.11     Issuance or Acquisition of Capital Stock. Not, without
executing and delivering, or causing to be executed and delivered, to the
Administrative Agent such agreements, documents and instruments as the
Administrative Agent may reasonably request for the purpose of perfecting its
security interest therein, issue or acquire any Capital Stock constituting
Collateral consisting of an interest in a partnership or a limited liability
company that (i) is dealt in or traded on a securities exchange or in a
securities market, (ii) by its terms expressly provides that it is a security
governed by Article 8 of the UCC, (iii) is an investment company security, (iv)
is held in a securities account or (v) constitutes a Security or a Financial
Asset (as each is defined in the UCC).

SECTION 5. RIGHTS OF THE ADMINISTRATIVE AGENT AND PLEDGOR.

         5.1      Power of Attorney. Each Pledgor hereby irrevocably and with
the power of substitution constitutes and appoints the Administrative Agent on
behalf of the holders of the Secured Obligations and any officer or agent
thereof, with full power of substitution, as its true and lawful
attorney-in-fact with full irrevocable power and authority in the place and
stead and in the name of each Pledgor or in its own name, from time to time in
the Administrative Agent's discretion during the continuance of an Event of
Default and prior to the Collateral Termination Date, to take any and all action
and to execute any and all documents and instruments which may be necessary or
desirable to accomplish the purposes of this Agreement and, without limiting the
generality of the foregoing, hereby gives the Administrative Agent the power and
right on behalf of the Pledgors and in its own name to do any of the following
after the occurrence and during the continuance of an Event of Default and to
the extent permitted by applicable laws, without notice to or the consent of the
Pledgors:

                           of or in exchange for any of the Collateral and, in

                           and all monies due and to become due thereunder
                           directly to the Administrative Agent or as the
                           Administrative Agent shall direct, (ii) to receive
                           payment of and receipt for any and all monies,
                           claims, and other amounts due and to become due at
                           any time in respect of or arising out of any
                           Collateral; (iii) to sign and endorse any drafts,
                           assignments, proxies, stock powers, verifications,
                           notices, and other documents relating to the
                           Collateral; (iv) to commence and prosecute any suit,
                           actions or proceedings at law or in equity in any
                           court of competent jurisdiction to collect the
                           Collateral or any part thereof and to enforce any
                           other right in respect of any Collateral; (v) to
                           defend any suit, action, or proceeding brought
                           against any Pledgor with respect to any Collateral;
                           (vi) to settle, compromise, or adjust any suit,
                           action, or proceeding described in clause (v) above
                           and, in connection therewith, to give such discharges
                           or releases as the Administrative Agent may deem
                           appropriate; (vii) to exchange any of the Collateral
                           for other property upon any merger, consolidation,
                           reorganization, recapitalization, or other
                           readjustment of the issuer thereof and, in connection
                           therewith, deposit any of the Collateral with any
                           committee, depositary, transfer agent, registrar, or
                           other designated agency upon such terms as the
                           Administrative Agent may determine; (viii) to add or
                           release any guarantor, endorser, surety, or other
                           party to any of the Collateral or the Secured

                           agreement with respect to or otherwise deal with any
                           of the Collateral as fully and completely as though
                           the Administrative Agent were the absolute owner
                           thereof for all purposes, and to do, at the
                           Administrative Agent's option and such Pledgor's
                           expense, at any time, or from time to time, all acts
                           and things which the Administrative Agent deems
                           necessary to protect, preserve, or realize upon the
                           Collateral and the Administrative Agent's security
                           interest; (x) to execute and deliver all assignments,
                           conveyances, statements, financing statements,
                           renewal financing statements, security and pledge
                           agreements, affidavits, notices and other agreements,
                           instruments and documents that the Administrative
                           Agent may reasonably deem appropriate in order to
                           perfect and maintain the security interests and liens
                           granted in this Agreement and in order to fully
                           consummate all of the transactions contemplated
                           herein; and (xi) to vote for a shareholder
                           resolution, or to sign an instrument in writing,
                           sanctioning the transfer of any or all of the
                           Collateral into the name of the Administrative Agent
                           or one or more of the holders of the Secured
                           Obligations or into the name of any transferee to
                           whom the Collateral or any part thereof may be sold
                           pursuant to Section 6.2 hereof.

This power of attorney is a power coupled with an interest and shall be
irrevocable. The Administrative Agent shall be under no duty to exercise or
withhold the exercise of any of the rights, powers, privileges,

                                       7
<PAGE>

and options expressly or implicitly granted to the Administrative Agent in this
Agreement, and shall not be liable for any failure to do so or any delay in
doing so. The Administrative Agent shall not be liable for any act or omission
or for any error of judgment or any mistake of fact or law in its individual
capacity or in its capacity as attorney-in-fact except acts or omissions
constituting or resulting from its willful misconduct or gross negligence. This
power of attorney is conferred on the Administrative Agent solely to protect,
preserve, and realize upon its security interest in the Collateral.

         5.2      Voting Rights. Until written notice shall be given to the
Pledgors in accordance with Section 6.2(d) that the Administrative Agent has
exercised its rights under Section 6.2(d) to vote the Collateral (provided,
however, if the Administrative Agent is prevented from providing such notice as
a result of Section 362 of the United States Bankruptcy Code or similar law the
Pledgors shall be entitled to exercise such rights so long as no Event of
Default shall have occurred and be continuing), a Pledgor shall be entitled to
exercise any and all voting and other rights relating or pertaining to the
Collateral or any part thereof and the Administrative Agent shall execute and
deliver (or cause to be executed and delivered) to such Pledgor all such proxies
and other instruments as such Pledgor may reasonably request for the purpose of
enabling such Pledgor to exercise the voting and other rights which it is
entitled to exercise pursuant to this sentence).

         5.3      Collateral Proceeds. Until written notice shall be given to
the Pledgors in accordance with Section 6.2(d) that the Administrative Agent has
exercised its rights under Section 6.2(d) to vote the Collateral, each Pledgor
shall be entitled to receive and collect for its own use all Collateral
Proceeds.

         5.4      Performance by the Administrative Agent of the Pledgors'
Obligations. If an Event of Default has occurred and is continuing or if a
Pledgor fails to perform or comply with any of its agreements contained herein,
the Administrative Agent may perform or cause performance of or compliance with
such agreement and in so doing may expend such sums as the Administrative Agent
may reasonably deem advisable in the performance thereof. All such expenses of
the Administrative Agent so expended, together with interest thereon at the rate
of interest provided in the Credit Agreement, shall be payable by the Pledgors
on a joint and several basis to the Administrative Agent on demand and shall
constitute Secured Obligations secured by this Agreement.

         5.5      The Administrative Agent's Duty of Care. Other than the
exercise of reasonable care in the physical custody of the Collateral while held
by the Administrative Agent hereunder, the Administrative Agent shall have no
responsibility for or obligation or duty with respect to all or any part of the
Collateral or any matter or proceeding arising out of or relating thereto,
including, without limitation, any obligation or duty to collect any sums due in
respect thereof or to protect or preserve any rights against prior parties or
any other rights pertaining thereto, it being understood and agreed that Pledgor
shall be responsible for preservation of all rights in the Collateral. Without
limiting the generality of the foregoing, the Administrative Agent shall be
conclusively deemed to have exercised reasonable care in the custody of the
Collateral if the Administrative Agent takes such action, for purposes of
preserving rights in the Collateral, as Pledgor may reasonably request in
writing, but no failure or omission or delay by the Administrative Agent in
complying with any such request by Pledgor, and no refusal by the Administrative
Agent to comply with any such request by Pledgor, shall of itself be deemed to
be a failure to exercise reasonable care.

SECTION 6. EVENTS OF DEFAULT AND REMEDIES.

         6.1      Events of Default. The Pledgors shall be in default under this
Agreement upon the occurrence of and during the continuation of any of the
events or conditions defined as Events of Default in the Credit Agreement (an
"Event of Default").

                                       8
<PAGE>

         6.2      Rights and Remedies. Prior to the Collateral Termination Date,
upon the occurrence of an Event of Default and so long as the same shall be
continuing, the Administrative Agent shall have the following rights and
remedies to the extent not prohibited by applicable laws:

                  (a)      In addition to all other rights and remedies granted
                           to the Administrative Agent in this Agreement and in
                           any other instrument or agreement securing,
                           evidencing, or relating to the Secured Obligations,
                           the Administrative Agent shall have all of the rights
                           and remedies of a secured party under the UCC of the
                           jurisdiction applicable to the affected Collateral.
                           Without limiting the generality of the foregoing, the
                           Administrative Agent may (i) without demand or notice
                           to the Pledgors, collect, receive, or take possession
                           of the Collateral or any part thereof, (ii) sell or
                           otherwise dispose of the Collateral, or any part
                           thereof, in one or more parcels at public or private
                           sale or sales, at the Administrative Agent's offices
                           or elsewhere, for cash, on credit, or for future
                           delivery without assumption of any credit risk,
                           and/or (iii) bid and become a purchaser at any such
                           sale free of any right or equity of redemption in any
                           of the Pledgors, which right or equity is hereby
                           expressly waived and released by all of the Pledgors.
                           Upon the request of the Administrative Agent, any of
                           the Pledgors shall assemble the Collateral and make
                           it available to the Administrative Agent at any place
                           designated by the Administrative Agent that is
                           reasonably convenient to such Pledgor and the
                           Administrative Agent. Each of the Pledgors agrees
                           that the Administrative Agent shall not be obligated
                           to give more than ten (10) days' prior written notice
                           of the time and place of any public sale or of the
                           time after which any private sale may take place and
                           that such notice shall constitute reasonable notice
                           of such matters. Each of the Pledgors shall be
                           liable, jointly and severally, for all reasonable
                           expenses of retaking, holding, preparing for sale, or
                           the like, and all reasonable attorneys' fees and
                           other reasonable expenses incurred by the
                           Administrative Agent in connection with the
                           collection of the Secured Obligations and the
                           enforcement of the Administrative Agent's rights
                           under this Agreement, in each case during the
                           continuance of an Event of Default, all of which
                           expenses and fees shall constitute additional Secured
                           Obligations secured by this Agreement. The
                           Administrative Agent may apply the Collateral against
                           the Secured Obligations then due and payable in such
                           order and manner as it shall elect in its sole
                           discretion. Each of the Pledgors shall remain liable
                           for any deficiency (subject to Section 7.16 hereof)
                           together with interest thereon at the Default Rate if
                           the proceeds of any sale or disposition of the
                           Collateral are insufficient to pay the Secured
                           Obligations. Each of the Pledgors waives all rights
                           of marshaling in respect of the Collateral.

                  (b)      The Administrative Agent may cause any or all of the
                           Collateral held by it to be transferred into the name
                           of the Administrative Agent or the name or names of
                           the Administrative Agent's nominee or nominees (in
                           each case as pledgee hereunder).

                  (c)      The Administrative Agent shall be entitled to receive
                           all dividends and cash distributions payable in
                           respect of the Collateral. Pledgor shall execute
                           notice letters, in form and substance satisfactory to
                           the Administrative Agent (as and when requested by
                           the Administrative Agent), notifying the Company or
                           Companies of the fact of this Agreement and directing
                           the Company or Companies to make payment directly to
                           the Administrative Agent of all of the distributions
                           which are due and owing to Pledgor by the Company or
                           Companies,

                                       9
<PAGE>

                           and directing the Company or Companies to accompany
                           each transmission of such distributions to the
                           Administrative Agent with a report in such form as
                           the Administrative Agent may reasonably require in
                           order to identify (i) the type of distribution being
                           made, and (ii) the calculations made by the Company
                           or Companies to determine the amount of the
                           distribution distributed to the Administrative Agent.

                  (d)      The Administrative Agent shall have the right, but
                           shall not be obligated to, exercise or cause to be
                           exercised all voting rights and powers in respect of
                           the Collateral, and Pledgor shall deliver to the
                           Administrative Agent, if requested by the
                           Administrative Agent, irrevocable proxies with
                           respect to the Collateral in form satisfactory to the
                           Administrative Agent.

Because of applicable securities laws, including without limitation, the
Securities Act of 1933, as amended, and other applicable state securities laws,
there may be legal restrictions or limitations affecting attempts of the
Administrative Agent to dispose of the Collateral in the enforcement of its
rights and remedies hereunder, the Administrative Agent is hereby authorized by
the Pledgors, but not obligated, upon the occurrence and during the continuance
of an Event of Default, to the extent permitted by applicable law, to sell all
or any part of the Collateral at private sale, subject to investment letters or
in any other manner which will not require the Collateral or any part thereof,
to be registered in accordance with the Securities Act of 1933, as amended, or
the rules and regulations promulgated thereunder, or any other applicable
securities law or regulation. The Pledgors specifically agree that under these
circumstances, such a sale is a commercially reasonable method of disposition of
the Collateral. The Administrative Agent is also hereby authorized by the
Pledgors, but not obligated, to take such actions, give such notices, obtain
such rulings and consents, and do such other things as the Administrative Agent
may deem appropriate in the event of such a sale or disposition of any of the
Collateral. The Pledgors acknowledge that the Administrative Agent may, in its
reasonable discretion, approach a restricted number of potential purchasers and
that a sale under such circumstances may yield a lower price for the Collateral
or any part or parts thereof than would otherwise be obtainable if the same were
registered and sold in the open market, the Pledgors agrees that such private
sale shall constitute a commercially reasonable method of disposing of the
Collateral in view of the time, expense, and potential liability to the parties
of such transactions of registration of the Collateral in accordance with
applicable securities laws.

         6.3      Application of Proceeds. Upon the occurrence and during the
continuation of an Event of Default, any payments in respect of the Secured
Obligations and any proceeds of the Collateral, when received by the
Administrative Agent or any of the holders of the Secured Obligations in cash or
its equivalent, will be applied in reduction of the Secured Obligations in the
order set forth in the Credit Agreement.

SECTION 7. MISCELLANEOUS.

         7.1      No Waiver; Cumulative Remedies. No failure on the part of the
Administrative Agent to exercise and no delay in exercising, and no course of
dealing with respect to, any right, power, privilege or remedy under this
Agreement shall operate as a waiver thereof, nor shall any single or partial
exercise of any right, power, privilege or remedy under this Agreement preclude
any other or further exercise thereof or the exercise of any other right, power,
privilege or remedy. To the fullest extent permitted by applicable laws, the
rights, powers, privileges and remedies provided for in this Agreement are
cumulative and not exclusive of any rights, powers, privileges and remedies
provided by law. The Administrative Agent may exercise any right, power,
privilege or remedy under this Agreement or under applicable law against any
Pledgor without enforcing any rights, powers, privileges or remedies against any
other Pledgor under this Agreement or otherwise, each of the Pledgors expressly
waiving any rights

                                       10
<PAGE>

or requirements that the Administrative Agent or any Lender first enforce any
right, power, privilege or remedy against the Borrower, any other Pledgor or any
other Collateral for the Secured Obligations.

         7.2      Successors and Assigns. This Agreement shall be binding upon
and inure to the benefit of each Pledgor and the Administrative Agent for the
benefit of the holders of the Secured Obligations and their respective heirs,
successors, and assigns, except that none of the Pledgors may assign any of its
rights or obligations under this Agreement without the prior written consent of
the Required Lenders under the Credit Agreement except to the extent permitted
by the Credit Agreement. To the fullest extent permitted by law, each Pledgor
hereby releases the Administrative Agent and each holder of the Secured
Obligations, and their respective successors and assigns, from any liability for
any act or omission relating to this Agreement or the Collateral, except for any
liability arising from the gross negligence or willful misconduct of the
Administrative Agent or such holder, or their respective officers, employees or
agents.

         7.3      Notices. All notices required or permitted to be given under
this Agreement shall be given as provided in Section 11.02 of the Credit
Agreement.

         7.4      Governing Law; Submission to Jurisdiction; Waiver of Jury
Trial; Arbitration.

         (a)      THIS AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED IN
ACCORDANCE WITH, the LAWS OF THE STATE OF NEW YORK applicable to agreements made
and to be performed entirely within such State; PROVIDED THAT THE PARTIES HERETO
SHALL RETAIN ALL RIGHTS ARISING UNDER FEDERAL LAW.

         (b)      ANY LEGAL ACTION OR PROCEEDING WITH RESPECT TO THIS AGREEMENT
OR ANY OTHER LOAN DOCUMENT MAY BE BROUGHT IN THE COURTS OF THE STATE OF NEW YORK
SITTING IN NEW YORK, NEW YORK OR OF THE UNITED STATES FOR THE SOUTHERN DISTRICT
OF SUCH STATE, AND BY EXECUTION AND DELIVERY OF THIS AGREEMENT, EACH PLEDGOR AND
THE ADMINISTRATIVE Agent, ON BEHALF OF ITSELF AND EACH LENDER, CONSENTS, FOR
ITSELF AND IN RESPECT OF ITS PROPERTY, TO THE NON-EXCLUSIVE JURISDICTION OF
THOSE COURTS. EACH PLEDGOR AND THE ADMINISTRATIVE Agent, ON BEHALF OF ITSELF AND
EACH LENDER, IRREVOCABLY WAIVES ANY OBJECTION, INCLUDING ANY OBJECTION TO THE
LAYING OF VENUE OR BASED ON THE GROUNDS OF FORUM NON CONVENIENS, WHICH IT MAY
NOW OR HEREAFTER HAVE TO THE BRINGING OF ANY ACTION OR PROCEEDING IN SUCH
JURISDICTION IN RESPECT OF THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT OR OTHER
DOCUMENT RELATED THERETO. EACH PLEDGOR AND THE ADMINISTRATIVE Agent, ON BEHALF
OF ITSELF AND EACH LENDER, WAIVES PERSONAL SERVICE OF ANY SUMMONS, COMPLAINT OR
OTHER PROCESS, WHICH MAY BE MADE BY ANY OTHER MEANS PERMITTED BY THE LAW OF SUCH
STATE.

         7.5      Waiver of Right to Trial by Jury.

         7.8      Amendments and Waivers. This Agreement and the provisions
hereof may not be amended, waived, modified, changed, discharged or terminated
except as set forth in Section 11.01 of the Credit Agreement.

together shall constitute one and the same instrument.

         7.10     Severability. Any provision of this Agreement which is

acknowledge that each of them has had the benefit of legal counsel of its own
choice and has been afforded an opportunity to review this Agreement with its

extension, or renewal of this Agreement, the Secured Obligations, or any
document or instrument evidencing, securing, or otherwise relating to the
Secured Obligations, or any release, subordination, or impairment of collateral,
or any waiver, consent, extension, indulgence, compromise, settlement, or other
action or inaction in respect of this Agreement, the Secured Obligations, or any

Pledgor (without recourse and without any representation or warranty), such of
the Collateral as may be in the possession of the Lender and as has not
theretofore been sold or otherwise applied pursuant to this Agreement or the
Credit Agreement. Upon such release and redelivery, this Agreement shall
terminate.

UNDERSTANDINGS, WHETHER WRITTEN OR ORAL, RELATING TO THE SUBJECT MATTER HEREOF.

         7.15     Other Security. To the extent that any of the Secured
Obligations are now or hereafter secured by property other than the Collateral
(including, without limitation, real and other personal property owned by a
Pledgor), or by a guarantee, endorsement or property of any other Person in
favor of the Administrative Agent on behalf of the holders of the Secured
Obligations, then the Administrative Agent shall have the right to proceed
against such other property, guarantee or endorsement upon the occurrence and
during the continuance of any Event of Default, and the Administrative Agent
shall have the right, in its sole discretion, to determine which rights,
security, liens, security interests or remedies the Administrative Agent shall
at any time pursue, relinquish, subordinate, modify or take with respect
thereto, without in any way modifying or affecting any of them or the Secured
Obligations or any of the rights of the Administrative Agent or the holders of
the Secured Obligations under this Agreement, under any of the other Loan
Documents or under any other document relating to the Secured Obligations.

         7.16     Joint and Several Obligations of Pledgors.

         (a)      Each of the Pledgors is accepting joint and several liability
hereunder in consideration of the financial accommodation to be provided by the
holders of the Secured Obligations, for the mutual benefit, directly and
indirectly, of each of the Pledgors and in consideration of the undertakings of
each of the Pledgors to accept joint and several liability for the obligations
of each of them.

         (b)      Each of the Pledgors jointly and severally hereby irrevocably
and unconditionally accepts, not merely as a surety but also as a co-debtor,
joint and several liability with the other Pledgors with respect to the payment
and performance of all of the Secured Obligations arising under this Agreement,
the other Loan Documents and any other documents relating to the Secured
Obligations, it being the intention of the parties hereto that all the Secured
Obligations shall be the joint and several obligations of each of the Pledgors
without preferences or distinction among them.

         (c)      Notwithstanding any provision to the contrary contained
herein, in any other of the Loan Documents or in any other documents relating to
the Secured Obligations, the obligations of each Guarantor under the Credit
Agreement, the other Loan Documents and the documents relating to the Secured
Obligations shall be limited to an aggregate amount equal to the largest amount
that would not render such obligations subject to avoidance under Section 548 of
the United States Bankruptcy Code or any comparable provisions of any applicable
state law.
