      4.2 Pledged Equity Interests(a) Representations and Warranties. The
Pledgor hereby represents and warrants that:

                  (i) Schedule 4.2(A) sets forth all of the Pledged Equity
      Interests owned by the Pledgor and such Pledged Equity Interests
      constitutes the percentage of issued and outstanding shares of stock of
      the Company;

                  (ii) it is the record and beneficial owner of the Pledged
      Equity Interests free of all Liens, rights or claims of other Persons
      (other than Permitted Liens) and there are no outstanding warrants,
      options or other rights to purchase, or shareholder, voting trust or
      similar agreements outstanding with respect to, or property that is
      convertible into, or that requires the issuance or sale of, any Pledged
      Equity Interests;

                  (iii) no consent of any Person is necessary in connection with
      the creation, perfection or first priority status of the security interest
      of the Collateral Agent in any Pledged Equity Interests or the exercise by
      the Collateral Agent of the voting or other rights provided for in this
      Agreement or the exercise of remedies in respect thereof.

            (b) Covenants and Agreements. The Pledgor hereby covenants and
agrees that:

                  (i) in the event it acquires rights in any Pledged Equity
      Interests after the date hereof, it shall deliver to the Collateral Agent
      a completed Pledge Supplement, substantially in the form of Exhibit A
      attached hereto, together with all Supplements to Schedules thereto,
      reflecting such new Pledged Equity Interests. Notwithstanding the
      foregoing, it is understood and agreed that the security interest of the
      Collateral Agent shall attach to all Pledged Equity Interests immediately
      upon the Pledgor's acquisition of rights therein and shall not be affected
      by the failure of the Pledgor to deliver a supplement to Schedule 4.4 as
      required hereby;

                  (ii) except as provided in the next sentence, in the event the
      Pledgor receives any dividends, interest or distributions on any Pledged
      Equity Interests, or any securities or other property upon the merger,
      consolidation, liquidation or dissolution of the Company, then (a) such
      dividends, interest or distributions and securities or other property
      shall be included in the definition of Collateral without further action
      and (b) the Pledgor shall immediately take all steps, if any, necessary or
      advisable to ensure the validity, perfection, priority and, if applicable,
      control of the Collateral Agent over such Pledged Equity Interests
      (including, without limitation, delivery thereof to the Collateral Agent)
      and pending any such action the Pledgor shall be deemed to hold such
      dividends, interest, distributions, securities or other property in trust
      for the benefit of the Collateral Agent and shall segregate such
      dividends, distributions, securities or other property from all other
      property of the Pledgor. Notwithstanding the foregoing, so long as no
      Event of Default shall have occurred and be continuing, the Collateral
      Agent authorizes the Pledgor to retain all ordinary cash dividends and
      distributions paid in the normal course of the business of the issuer and
      consistent with the past practice of the issuer and all scheduled payments
      of interest; and

                  (iii) without the prior written consent of the Collateral
      Agent, it shall not permit the Company to merge or consolidate unless (i)
      the surviving entity creates a security interest that is perfected by a
      filed financing statement (that is not effective solely under section

      other equity interests of the surviving or resulting corporation, limited
      liability company, partnership or other entity which is a Subsidiary of
      the Pledgor and which is owned by the Pledgor is, upon such merger or

      Interests in which it currently has rights it shall comply with the
      provisions of this Section 4.2(c)(i) on or before the Credit Date and with
      respect to any Pledged Equity Interests hereafter acquired by the Pledgor
      it shall comply with the provisions of this Section 4.2(c)(i) within
      fifteen (15) days of acquiring rights therein, in each case in form and
      substance reasonably satisfactory to the Collateral Agent. With respect to
      any Pledged Equity Interests that is represented by a certificate or that
      is an "instrument," it shall cause such certificate or instrument to be
      delivered to the Collateral Agent, indorsed in blank by an "effective
      indorsement" (as defined in Section 8-107 of the UCC), regardless of
      whether such certificate constitutes a "certificated security" for
      purposes of the UCC. With respect to any Pledged Equity Interests that is
      an "uncertificated security" for purposes of the UCC, it shall cause the
      Company to execute an agreement substantially in the form of Exhibit B
      hereto, pursuant to which such issuer agrees to comply with the Collateral
      Agent's instructions with respect to such uncertificated security without
      further consent by the Pledgor.

            (d) Voting and Distributions.

                  (i) So long as no Event of Default shall have occurred and be
      continuing:

            this Agreement or elsewhere herein or in the Credit Agreement, the
            Pledgor shall be entitled to exercise or refrain from exercising any
            and all voting and other consensual rights pertaining to the Pledged
            Equity Interests or any part thereof for any purpose not
            inconsistent with the terms of this Agreement or the Credit
            Agreement; and

      (2)   the Collateral Agent shall promptly execute and deliver (or cause to
            be executed and delivered) to the Pledgor all proxies, and other
            instruments as the Pledgor may from time to time reasonably request
            for the purpose of enabling the Pledgor to exercise the voting and
            other consensual rights when and to the extent which it is entitled
            to exercise pursuant to clause (1) above.

                  (ii) Upon the occurrence and during the continuation of an
      Event of Default and upon written notice from the Collateral Agent to the
      Pledgor of the Collateral Agent's intention to exercise such rights:

      (1)   all rights of the Pledgor to exercise the voting and other
            consensual rights which it would otherwise be entitled to exercise
            pursuant hereto shall cease and all such rights shall thereupon
            become vested in the Collateral Agent who shall thereupon have the
            sole right to exercise such voting and other consensual rights; and

                                       7

                                                                  EXECUTION COPY
<PAGE>

      (2)   in order to permit the Collateral Agent to exercise the voting and
            other consensual rights which it may be entitled to exercise
            pursuant hereto and to receive all dividends and other distributions
            which it may be entitled to receive hereunder: (1) the Pledgor shall
            promptly execute and deliver (or cause to be executed and delivered)
            to the Collateral Agent all proxies, dividend payment orders and
            other instruments as the Collateral Agent may from time to time
            reasonably request and (2) the Pledgor acknowledges that the
            Collateral Agent may utilize the power of attorney set forth in
            Section 6.1.

SECTION 5. FURTHER ASSURANCES.

      5.1 FURTHER ASSURANCES.

            (a) The Pledgor agrees that from time to time, at its expense, that
it shall promptly execute and deliver all further instruments and documents, and
take all further action, that may be necessary, or that the Collateral Agent may
reasonably request, in order to create and/or maintain the validity, perfection
or priority of and protect any security interest granted hereby or to enable the
Collateral Agent to exercise and enforce its rights and remedies hereunder with
respect to any Collateral. Without limiting the generality of the foregoing, the
Pledgor shall:

                  (i) file such financing or continuation statements, or
      amendments thereto, and execute and deliver such other agreements,
      instruments, endorsements, powers of attorney or notices, as may be
      necessary or as the Collateral Agent may reasonably request, in order to
      perfect and preserve the security interests granted hereby; and

                  (ii) at the Collateral Agent's request, appear in and defend
      any action or proceeding that may affect the Pledgor's title to or the
      Collateral Agent's security interest in all or any part of the Collateral.

      The Pledgor hereby authorizes the Collateral Agent to file a Record or
Records, including, without limitation, financing or continuation statements,
and amendments thereto, in any jurisdictions and with any filing offices as the
Collateral Agent may determine, in its sole discretion, are necessary or
advisable to perfect the security interest granted to the Collateral Agent
herein. Such financing statements may describe the Collateral in the same manner
as described herein or may contain an indication or description of collateral
that describes such property in any other manner as the Collateral Agent may
determine, in its sole discretion, is necessary, advisable or prudent to ensure
the perfection of the security interest in the Collateral granted to the
Collateral Agent herein. The Pledgor shall furnish to the Collateral Agent from
time to time statements and schedules further identifying and describing the
Collateral and such other reports in connection with the Collateral as the
Collateral Agent may reasonably request, all in reasonable detail.

SECTION 6. COLLATERAL AGENT APPOINTED ATTORNEY-IN-FACT.

      6.1 POWER OF ATTORNEY. The Pledgor hereby irrevocably appoints the
Collateral Agent (such appointment being coupled with an interest) as its
attorney-in-fact, with full authority in its place and stead and in its name, in
the name of the Collateral Agent or otherwise, from time to time in the
Collateral Agent's discretion to take any action and to execute any instrument
that the Collateral Agent may deem reasonably necessary or advisable to
accomplish the purposes of this Agreement, including, without limitation, the
following:

                                       8

                                                                  EXECUTION COPY
<PAGE>

            (a) upon the occurrence and during the continuance of any Event of
Default, to ask for, demand, collect, sue for, recover, compound, receive and
give acquittance and receipts for moneys due and to become due under or in
respect of any of the Collateral;

            (b) upon the occurrence and during the continuance of any Event of
Default, to receive, endorse and collect any drafts or other instruments,
documents and chattel paper in connection with clause (a) above;

            (c) upon the occurrence and during the continuance of any Event of
Default, to file any claims or take any action or institute any proceedings that
the Collateral Agent may deem necessary or desirable for the collection of any
of the Collateral or otherwise to enforce the rights of the Collateral Agent
with respect to any of the Collateral;

            (d) to prepare and file any UCC financing statements against the
Pledgor as debtor;

            (e) to take or cause to be taken all actions necessary to perform or
comply or cause performance or compliance with the terms of this Agreement,
including, without limitation, access to pay or discharge taxes or Liens other
than Permitted Liens levied or placed upon or threatened against the Collateral,
the legality or validity thereof and the amounts necessary to discharge the same
to be determined by the Collateral Agent in its sole discretion, any such
payments made by the Collateral Agent to become obligations of the Pledgor to
the Collateral Agent, due and payable immediately without demand; and

            (f) generally to sell, transfer, pledge, make any agreement with
respect to or otherwise deal with any of the Collateral as fully and completely
as though the Collateral Agent were the absolute owner thereof for all purposes,
and to do, at the Collateral Agent's option and the Pledgor's expense, at any
time or from time to time, all acts and things that the Collateral Agent deems
reasonably necessary to protect, preserve or realize upon the Collateral and the
Collateral Agent's security interest therein in order to effect the intent of
this Agreement, all as fully and effectively as the Pledgor might do.

            Anything in this Section 6.1 to the contrary notwithstanding, the
Collateral Agent agrees that, except as provided in Section 6.1(d) and subject
to the next sentence, it will not exercise any rights under the power of
attorney provided for in this Section 6.1 unless an until an Event of Default
shall have occurred and be continuing. If the Pledgor fails to perform or comply
with any of its agreements contained herein, the Collateral Agent, at its
option, but without any obligation so to do, may perform or comply, or otherwise
cause performance or compliance, with such agreement; provided, however, that
unless an Event of Default has occurred and is continuing or time is of the
essence, the Collateral Agent shall not exercise this power without first making
demand on the Pledgor and the Pledgor has failed to comply immediately
therewith.

      6.2 NO DUTY ON THE PART OF COLLATERAL AGENT OR SECURED PARTIES. The powers
conferred on the Collateral Agent hereunder are solely to protect the interests
of the Collateral Agent in the Collateral and shall not impose any duty upon the
Collateral Agent or any Secured Party to exercise any such powers. The
Collateral Agent and the Secured Parties shall be accountable only for amounts
that they actually receive as a result of the exercise of such powers, and
neither they nor any of their officers, directors, employees or agents shall be
responsible to the Pledgor for any act or failure to act hereunder, except for
their own gross negligence or willful misconduct.

                                                                  EXECUTION COPY

SECTION 7. REMEDIES.

      7.1 GENERALLY.

            (a) If any Event of Default shall have occurred and be continuing,
the Collateral Agent may exercise in respect of the Collateral, in addition to
all other rights and remedies provided for herein or otherwise available to it
at law or in equity, all the rights and remedies of the Collateral Agent on
default under the UCC (whether or not the UCC applies to the affected
Collateral) to collect, enforce or satisfy any Secured Obligations then owing,
whether by acceleration or otherwise, and also may pursue any of the following
separately, successively or simultaneously:

                  (i) require the Pledgor, and the Pledgor hereby agrees that it
      shall at its expense and promptly upon request of the Collateral Agent
      forthwith, assemble all or part of the Collateral as directed by the
      Collateral Agent and make it available to the Collateral Agent at a place
      to be designated by the Collateral Agent that is reasonably convenient to
      both parties; and

                  (ii) without notice except as specified below or under the
      UCC, sell, assign or otherwise dispose of the Collateral or any part
      thereof in one or more parcels at public or private sale, at any of the
      Collateral Agent's offices or elsewhere, for cash, on credit or for future
      delivery, at such time or times and at such price or prices and upon such
      other terms as the Collateral Agent may deem commercially reasonable.

            (b) The Collateral Agent or any Secured Party may be the purchaser
of any or all of the Collateral at any public or private (to the extent to the
portion of the Collateral being privately sold is of a kind that is customarily
sold on a recognized market or the subject of widely distributed standard price
quotations) sale in accordance with the UCC and the Collateral Agent, as
collateral agent for and representative of the Secured Parties, shall be
entitled, for the purpose of bidding and making settlement or payment of the
purchase price for all or any portion of the Collateral sold at any such sale
made in accordance with the UCC, to use and apply any of the Secured Obligations
as a credit on account of the purchase price for any Collateral payable by the
Collateral Agent at such sale. Each purchaser at any such sale shall hold the
property sold absolutely free from any claim or right on the part of the
Pledgor, and the Pledgor hereby waives (to the extent permitted by applicable
law) all rights of redemption, stay and/or appraisal which it now has or may at
any time in the future have under any rule of law or statute now existing or
hereafter enacted. The Pledgor agrees that, to the extent notice of sale shall
be required by law, at least ten (10) days notice to the Pledgor of the time and
place of any public sale or the time after which any private sale is to be made
shall constitute reasonable notification. The Collateral Agent shall not be
obligated to make any sale of Collateral regardless of notice of sale having
been given. The Collateral Agent may adjourn any public or private sale from
time to time by announcement at the time and place fixed therefor, and such sale
may, without further notice, be made at the time and place to which it was so
adjourned. The Pledgor hereby waives any claims against the Collateral Agent
arising by reason of the fact that the price at which any Collateral may have
been sold at such a private sale was less than the price which might have been
obtained at a public sale, even if the Collateral Agent accepts the first offer
received and does not offer such Collateral to more than one offeree. Nothing in
this Section shall in any way alter the rights of the Collateral Agent
hereunder.

            (c) The Pledgor recognizes that, by reason of certain prohibitions
contained in the Securities Act and applicable state securities laws, the
Collateral Agent may be compelled,

                                       10

                                                                  EXECUTION COPY
<PAGE>

with respect to any sale of all or any part of the Pledged Equity Interests
conducted without prior registration or qualification of such Pledged Equity
Interests under the Securities Act and/or such state securities laws, to limit
purchasers to those who will agree, among other things, to acquire the Pledged
Equity Interests for their own account, for investment and not with a view to
the distribution or resale thereof. The Pledgor acknowledges that any such
private sale may be at prices and on terms less favorable than those obtainable
through a public sale without such restrictions (including a public offering
made pursuant to a registration statement under the Securities Act) and,
notwithstanding such circumstances, the Pledgor agrees that the fact that any
such sale is conducted as a private sale shall not, in and of itself, issue such
sale to not be deemed to have been made in a commercially reasonable manner and
that the Collateral Agent shall have no obligation to engage in public sales and
no obligation to delay the sale of any Pledged Equity Interests for the period
of time necessary to permit the issuer thereof to register it for a form of
public sale requiring registration under the Securities Act or under applicable
state securities laws, even if such issuer would, or should, agree to so
register it. If the Collateral Agent determines to exercise its right to sell
any or all of the Pledged Equity Interests, upon written request, the Pledgor
shall and shall cause the Company to furnish to the Collateral Agent all such
information as the Collateral Agent may request in order to determine the number
and nature of interest, shares or other instruments included in the Pledged
Equity Interests which may be sold by the Collateral Agent in exempt
transactions under the Securities Act and the rules and regulations of the
Securities and Exchange Commission thereunder, as the same are from time to time
in effect.

            (d) The Collateral Agent may sell the Collateral without giving any
warranties as to the Collateral. The Collateral Agent may specifically disclaim
or modify any warranties of title or the like. This procedure will not be
considered to adversely affect the commercial reasonableness of any sale of the
Collateral.

            (e) The Collateral Agent shall have no obligation to marshal any of
the Collateral.

      7.2 APPLICATION OF PROCEEDS(a) . Except as expressly provided elsewhere in
this Agreement, all proceeds received by the Collateral Agent in respect of any
sale, any collection from, or other realization upon all or any part of the
Collateral shall be applied in full or in part by the Collateral Agent in
accordance with the Intercreditor Agreement and the Credit Agreement.

      7.3 CASH PROCEEDS. All proceeds of any Collateral received by the Pledgor
consisting of cash, checks and other non-cash items (collectively, "CASH
PROCEEDS") shall, if an Event of Default shall have occurred and is continuing
be held by the Pledgor in trust for the Collateral Agent, segregated from its
other funds, and shall, forthwith upon its receipt, unless otherwise provided
pursuant to Section 4.4(a)(ii), be turned over to the Collateral Agent in the
exact form received by the Pledgor (duly indorsed by the Pledgor to the
Collateral Agent, if required) and held by the Collateral Agent in the
Collateral Account. Any Cash Proceeds received by the Collateral Agent (whether
from the Pledgor or otherwise): (i) if no Event of Default shall have occurred
and be continuing, shall be handled as required by this Agreement or the Credit
Agreement, or otherwise be turned over to the Pledgor and (ii) if an Event of
Default shall have occurred and be continuing, may, in the sole discretion of
the Collateral Agent, (A) be held by the Collateral Agent for the ratable
benefit of the Secured Parties, as collateral security for the Secured
Obligations (whether matured or unmatured) and/or (B) then or at any time
thereafter may be applied by the Collateral Agent against the Secured
Obligations then due and owing in accordance with the Intercreditor Agreement
and the Credit Agreement.

SECTION 8. COLLATERAL AGENT.

      The Collateral Agent has been appointed to act as Collateral Agent
hereunder by Lenders and, by their acceptance of the benefits hereof, the other
Secured Parties. The Collateral Agent shall be obligated, and shall have the
right hereunder, to make demands, to give notices, to exercise or refrain from
exercising any rights, and to take or refrain from taking any action (including,
without limitation, the release or substitution of Collateral), solely in
accordance with this Agreement, the Intercreditor Agreement and the Credit
Agreement; provided, the Collateral Agent shall, after payment in full of all
Obligations under the Credit Agreement and the other Credit Documents, exercise,
or refrain from exercising, any remedies provided for herein in accordance with
the instructions of the holders of a majority of the aggregate notional amount
(or, with respect to any Hedge Agreement that has been terminated in accordance
with its terms, the amount then due and payable (exclusive of expenses and
similar payments but including any early termination payments then due) under
such Hedge Agreement) under all Hedge Agreements. In furtherance of the
foregoing provisions of this Section, each Secured Party, by its acceptance of
the benefits hereof, agrees that it shall have no right individually to realize
upon any of the Collateral hereunder, it being understood and agreed by such
Secured Party that all rights and remedies hereunder may be exercised solely by
the Collateral Agent for the benefit of Secured Parties in accordance with the
terms of this Section. Collateral Agent may resign at any time by giving thirty
(30) days' prior written notice thereof to Lenders and the Pledgor. Upon any
such notice of resignation or any such removal, Requisite Lenders shall have the
right, upon five (5) Business Days' notice to the Administrative Agent, to
appoint a successor Collateral Agent. Upon the acceptance of any appointment as
Collateral Agent hereunder by a successor Collateral Agent, that successor
Collateral Agent shall thereupon succeed to and become vested with all the
rights, powers, privileges and duties of the retiring Collateral Agent under
this Agreement, and the retiring Collateral Agent under this Agreement shall
promptly (i) transfer to such successor Collateral Agent all sums, securities
and other items of Collateral held hereunder, together with all records and
other documents necessary or appropriate in connection with the performance of
the duties of the successor Collateral Agent under this Agreement, and (ii)
execute and deliver to such successor Collateral Agent or otherwise authorize
the filing of such amendments to financing statements, and take such other
actions, as may be necessary or appropriate in connection with the assignment to
such successor Collateral Agent of the security interests created hereunder,
whereupon such retiring Collateral Agent shall be discharged from its duties and
obligations under this Agreement. After any retiring Collateral Agent's
resignation hereunder as the Collateral Agent, the provisions of this Agreement
shall inure to its benefit as to any actions taken or omitted to be taken by it
under this Agreement while it was the Collateral Agent hereunder.

SECTION 9. CONTINUING SECURITY INTEREST; TRANSFER OF LOANS.

      This Agreement shall create a continuing security interest in the
Collateral and shall remain in full force and effect until the payment in full
of all Secured Obligations, the cancellation, cash collateralization or
termination of the Commitments and the cancellation, cash collateralization or
expiration of all outstanding Letters of Credit, be binding upon The Pledgor,
its successors and assigns, and inure, together with the rights and remedies of
the Collateral Agent hereunder, to the benefit of the Collateral Agent and its
successors, transferees and assigns. Without limiting the generality of the
foregoing, but subject to the terms of the Credit Agreement, any Lender may
assign or otherwise transfer any Loans held by it to any other Person, and such
other Person shall thereupon become vested with all the benefits in respect
thereof granted to Lenders herein or otherwise. Upon the payment in full of all
Secured Obligations, the cancellation or termination of the Commitments and the
cancellation, cash collateralization or

                                       12

                                                                  EXECUTION COPY
<PAGE>

expiration of all outstanding Letters of Credit, the security interest granted
hereby shall automatically terminate hereunder and of record and all rights to
the Collateral shall automatically revert to the Pledgor. Upon any such
termination the Collateral Agent shall, at Pledgor's expense, execute and
deliver to the Pledgor such documents as the Pledgor shall reasonably request to
evidence such termination.

SECTION 10. STANDARD OF CARE; COLLATERAL AGENT MAY PERFORM.

      The powers conferred on the Collateral Agent hereunder are solely to
protect its interest in the Collateral and shall not impose any duty upon it to
exercise any such powers. Except for the exercise of reasonable care in the
custody of any Collateral in its possession and the accounting for moneys
actually received by it hereunder, the Collateral Agent shall have no duty as to
any Collateral or as to the taking of any necessary steps to preserve rights
against prior parties or any other rights pertaining to any Collateral. The
Collateral Agent shall be deemed to have exercised reasonable care in the
custody and preservation of Collateral in its possession if such Collateral is
accorded treatment substantially equal to that which the Collateral Agent
accords its own property. Neither the Collateral Agent nor any of its directors,
officers, employees or agents shall be liable for failure to demand, collect or
realize upon all or any part of the Collateral or for any delay in doing so or
shall be under any obligation to sell or otherwise dispose of any Collateral
upon the request of the Pledgor or otherwise. If the Pledgor fails to perform
any agreement contained herein, the Collateral Agent may itself perform, or
cause performance of, such agreement, and the expenses of the Collateral Agent
incurred in connection therewith shall be payable by the Pledgor.

SECTION 11. MISCELLANEOUS.

      Any notice required or permitted to be given under this Agreement shall be
given in accordance with Section 10.1 of the Credit Agreement. No failure or
delay on the part of the Collateral Agent in the exercise of any power, right or
privilege hereunder or under any other Credit Document shall impair such power,
right or privilege or be construed to be a waiver of any default or acquiescence
therein, nor shall any single or partial exercise of any such power, right or
privilege preclude other or further exercise thereof or of any other power,
right or privilege. All rights and remedies existing under this Agreement and
the other Credit Documents are cumulative to, and not exclusive of, any rights
or remedies otherwise available. In case any provision in or obligation under
this Agreement shall be invalid, illegal or unenforceable in any jurisdiction,
the validity, legality and enforceability of the remaining provisions or
obligations, or of such provision or obligation in any other jurisdiction, shall
not in any way be affected or impaired thereby. All covenants hereunder shall be
given independent effect so that if a particular action or condition is not
permitted by any of such covenants, the fact that it would be permitted by an
exception to, or would otherwise be within the limitations of, another covenant
shall not avoid the occurrence of a Default or an Event of Default if such
action is taken or condition exists. This Agreement shall be binding upon and
inure to the benefit of the Collateral Agent and Pledgor and its respective
successors and assigns. The Pledgor shall not, without the prior written consent
of the Collateral Agent given in accordance with the Credit Agreement, assign
any right, duty or obligation hereunder. This Agreement and the other Credit
Documents embody the entire agreement and understanding between the Pledgor and
the Collateral Agent and supersede all prior agreements and understandings
between such parties relating to the subject matter hereof and thereof.
Accordingly, the Credit Documents may not be contradicted by evidence of prior,
contemporaneous or subsequent oral agreements of the parties. There are no
unwritten oral agreements between the parties. This Agreement may be executed in
one or more counterparts and by different parties hereto in separate
counterparts, each of which when so

                                       13

                                                                  EXECUTION COPY
<PAGE>

executed and delivered shall be deemed an original, but all such counterparts
together shall constitute but one and the same instrument; signature pages may
be detached from multiple separate counterparts and attached to a single
counterpart so that all signature pages are physically attached to the same
document.

            THIS AGREEMENT AND THE RIGHTS AND OBLIGATIONS OF THE PARTIES
HEREUNDER SHALL BE GOVERNED BY, AND SHALL BE CONSTRUED AND ENFORCED IN
ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK.

      IN WITNESS WHEREOF, the Pledgor and the Collateral Agent have caused this
Agreement to be duly executed and delivered by their respective officers

      the Intercreditor Agreement, priority and, if applicable, control of the
      Collateral Agent over such Pledged Equity Interests (including, without
      limitation, delivery thereof to the First Lien Collateral Agent or
      Collateral Agent, as applicable, in accordance with the Intercreditor
      Agreement) and pending any such action the Pledgor shall be deemed to hold
      such dividends, interest, distributions, securities or other property in
      trust for the benefit of the First Lien Collateral Agent and the
      Collateral Agent and shall segregate such dividends, distributions,
      securities or other property from all other property of the Pledgor.
      Notwithstanding the foregoing, so long as no Event of Default shall have
      occurred and be continuing, the Collateral Agent authorizes the Pledgor to
      retain all ordinary cash dividends and distributions paid in the normal
      course of the business of the issuer and consistent with the past practice
      of the issuer and all scheduled payments of interest; and

                  (iii) without the prior written consent of the Collateral
      Agent, it shall not permit the Company to merge or consolidate unless (i)
      the surviving entity

                                       7

<PAGE>

creates a security interest that is perfected by a filed financing statement
(that is not effective solely under section 9-508 of the UCC) in collateral in
which such new debtor has or acquires rights, and (ii) all the outstanding
capital stock or other equity interests of the surviving or resulting
corporation, limited liability company, partnership or other entity which is a
Subsidiary of the Pledgor and which is owned by the Pledgor is, upon such merger
or consolidation and subject to the terms of the Intercreditor Agreement,
pledged hereunder.

      (c)   Delivery and Control.

            (i) The Pledgor agrees that with respect to any Pledged Equity
Interests in which it currently has rights it shall comply with the provisions
of this Section 4.2(c)(i) on or before the Closing Date and with respect to any
Pledged Equity Interests hereafter acquired by the Pledgor it shall comply with
the provisions of this Section 4.2(c)(i) within fifteen (15) days of acquiring
rights therein, in each case in form and substance reasonably satisfactory to
the Collateral Agent. With respect to any Pledged Equity Interests that is
represented by a certificate or that is an "instrument," it shall cause such
certificate or instrument to be delivered to the First Lien Collateral Agent or
Collateral Agent, as applicable, in accordance with the Intercreditor Agreement,
indorsed in blank by an "effective indorsement" (as defined in Section 8-107 of
the UCC), regardless of whether such certificate constitutes a "certificated
security" for purposes of the UCC. With respect to any Pledged Equity Interests
that is an "uncertificated security" for purposes of the UCC, it shall cause the
Company to execute an agreement substantially in the form of Exhibit B hereto,
pursuant to which such issuer agrees to comply with the instructions of First
Lien Collateral Agent or Collateral Agent, as applicable in accordance with the
Intercreditor Agreement, with respect to such uncertificated security without
further consent by the Pledgor.

      (d)   Voting and Distributions.

            (i) So long as no Event of Default shall have occurred and be
continuing:

(1)   except as otherwise provided under the covenants and agreements in this
      Agreement or elsewhere herein or in the Parity Lien Documents, the Pledgor
      shall be entitled to exercise or refrain from exercising any and all
      voting and other consensual rights pertaining to the Pledged Equity
      Interests or any part thereof for any purpose not inconsistent with the
      terms of this Agreement or the Parity Lien Documents; and

(2)   the Collateral Agent shall promptly execute and deliver (or cause to be
      executed and delivered) to the Pledgor all proxies, and other instruments
      as the Pledgor may from time to time reasonably request for the purpose of
      enabling the Pledgor to exercise the voting and other consensual rights
      when and to the extent which it is entitled to exercise pursuant to clause
      (1) above.

            (ii) Upon the occurrence and during the continuation of an Event of
Default and upon written notice from the Collateral Agent to the Pledgor of the
Collateral Agent's intention to exercise such rights (subject to and in
accordance with the terms of the Intercreditor Agreement):

                                       8

<PAGE>

      (1)   all rights of the Pledgor to exercise the voting and other
            consensual rights which it would otherwise be entitled to exercise
            pursuant hereto shall cease and all such rights shall thereupon
            become vested in the Collateral Agent who shall thereupon have the
            sole right to exercise such voting and other consensual rights; and

      (2)   in order to permit the Collateral Agent to exercise the voting and
            other consensual rights which it may be entitled to exercise
            pursuant hereto and to receive all dividends and other distributions
            which it may be entitled to receive hereunder: (1) the Pledgor shall
            promptly execute and deliver (or cause to be executed and delivered)
            to the Collateral Agent all proxies, dividend payment orders and
            other instruments as the Collateral Agent may from time to time
            reasonably request and (2) the Pledgor acknowledges that the
            Collateral Agent may utilize the power of attorney set forth in
            Section 6.1.

SECTION 5.  FURTHER ASSURANCES; ADDITIONAL PARITY LIEN DEBT.

      5.1   FURTHER ASSURANCES.

            (a)   The Pledgor agrees that from time to time, at its expense,
that it shall promptly execute and deliver all further instruments and
documents, and take all further action, that may be necessary, or that the
Collateral Agent may reasonably request, in order to create and/or maintain the
validity, perfection or priority of and protect any security interest granted
hereby or to enable the Collateral Agent to exercise and enforce its rights and
remedies hereunder with respect to any Collateral. Without limiting the
generality of the foregoing, the Pledgor shall:

                  (i) file such financing or continuation statements, or
      amendments thereto, and execute and deliver, subject to the terms and
      conditions of the Intercreditor Agreement, such other agreements,
      instruments, endorsements, powers of attorney or notices, as may be
      necessary or as the Collateral Agent may reasonably request, in order to
      perfect and preserve the security interests granted hereby; and

                  (ii) at the Collateral Agent's request, appear in and defend
      any action or proceeding that may affect the Pledgor's title to or the
      Collateral Agent's security interest in all or any part of the Collateral.

      The Pledgor hereby authorizes the Collateral Agent to file a Record or
Records, including, without limitation, financing or continuation statements,
and amendments thereto, in any jurisdictions and with any filing offices as the
Collateral Agent may determine, in its sole discretion, are necessary or
advisable to perfect the security interest granted to the Collateral Agent
herein. Such financing statements shall describe the Collateral in the same
manner as described herein. The Pledgor shall furnish to the Collateral Agent
from time to time statements and schedules further identifying and describing
the Collateral and such other reports in connection with the Collateral as the
Collateral Agent may reasonably request, all in reasonable detail.

      5.2   ADDITIONAL PARITY LIEN DEBT. From time to time subsequent to the
date hereof, any Credit Party may incur additional Parity Lien Debt. The Secured
Obligations under such Parity Lien Debt shall be secured, Equally and Ratably,
by Liens in the Collateral granted to the Collateral Agent hereunder for the
benefit of all existing and future Parity Lien Claimholders. As a condition of
the issuance of any such additional Parity Lien Debt, Pledgor hereby agrees to

                                       9

<PAGE>

execute and deliver to Collateral Agent a lien affirmation substantially in the
form of Exhibit C attached hereto.

SECTION 6.  COLLATERAL AGENT APPOINTED ATTORNEY-IN-FACT.

      6.1   POWER OF ATTORNEY. Subject to the terms and conditions of the
Intercreditor Agreement, the Pledgor hereby irrevocably appoints the Collateral
Agent (such appointment being coupled with an interest) as its attorney-in-fact,
with full authority in its place and stead and in its name, in the name of the
Collateral Agent or otherwise, from time to time in the Collateral Agent's
discretion to take any action and to execute any instrument that the Collateral
Agent may deem reasonably necessary or advisable to accomplish the purposes of
this Agreement, including, without limitation, subject to the terms and
conditions of the Intercreditor Agreement, the following:

            (a) upon the occurrence and during the continuance of any Event of
Default, to ask for, demand, collect, sue for, recover, compound, receive and
give acquittance and receipts for moneys due and to become due under or in
respect of any of the Collateral;

            (b) upon the occurrence and during the continuance of any Event of
Default, to receive, endorse and collect any drafts or other instruments,
documents and chattel paper in connection with clause (a) above;

            (c) upon the occurrence and during the continuance of any Event of
Default, to file any claims or take any action or institute any proceedings that
the Collateral Agent may deem necessary or desirable for the collection of any
of the Collateral or otherwise to enforce the rights of the Collateral Agent
with respect to any of the Collateral;

            (d) to prepare and file any UCC financing statements against the
Pledgor as debtor;

            (e) to take or cause to be taken all actions necessary to perform or
comply or cause performance or compliance with the terms of this Agreement,
including, without limitation, access to pay or discharge taxes or Liens other
than Permitted Liens levied or placed upon or threatened against the Collateral,
the legality or validity thereof and the amounts necessary to discharge the same
to be determined by the Collateral Agent in its sole discretion, any such
payments made by the Collateral Agent to become obligations of the Pledgor to
the Collateral Agent, due and payable immediately without demand; and

            (f) generally to sell, transfer, pledge, make any agreement with
respect to or otherwise deal with any of the Collateral as fully and completely
as though the Collateral Agent were the absolute owner thereof for all purposes,
and to do, at the Collateral Agent's option and the Pledgor's expense, at any
time or from time to time, all acts and things that the Collateral Agent deems
reasonably necessary to protect, preserve or realize upon the Collateral and the
Collateral Agent's security interest therein in order to effect the intent of
this Agreement, all as fully and effectively as the Pledgor might do.

            Anything in this Section 6.1 to the contrary notwithstanding, the
Collateral Agent agrees that, except as provided in Section 6.1(d) and subject
to the next sentence, it will not exercise any rights under the power of
attorney provided for in this Section 6.1 unless an until an Event of Default
shall have occurred and be continuing. If the Pledgor fails to perform or comply
with any of its agreements contained herein, the Collateral Agent, at its
option, but without any obligation so to do, may perform or comply, or otherwise
cause performance or compliance, with

                                       10

<PAGE>

such agreement; provided, however, that unless an Event of Default has occurred
and is continuing or time is of the essence, the Collateral Agent shall not
exercise this power without first making demand on the Pledgor and the Pledgor
has failed to comply immediately therewith.

      6.2   NO DUTY ON THE PART OF COLLATERAL AGENT OR SECURED PARTIES. The
powers conferred on the Collateral Agent hereunder are solely to protect the
interests of the Collateral Agent in the Collateral and shall not impose any
duty upon the Collateral Agent or any Secured Party to exercise any such powers.
The Collateral Agent and the Secured Parties shall be accountable only for
amounts that they actually receive as a result of the exercise of such powers,
and neither they nor any of their officers, directors, employees or agents shall
be responsible to the Pledgor for any act or failure to act hereunder, except
for their own gross negligence or willful misconduct.

SECTION 7.  REMEDIES.

      7.1   GENERALLY.

            (a)   If any Event of Default shall have occurred and be continuing,
the Collateral Agent (subject to the terms and conditions of the Intercreditor
Agreement) may exercise in respect of the Collateral, in addition to all other
rights and remedies provided for herein or otherwise available to it at law or
in equity, all the rights and remedies of the Collateral Agent on default under
the UCC (whether or not the UCC applies to the affected Collateral) to collect,
enforce or satisfy any Secured Obligations then owing, whether by acceleration
or otherwise, and subject to the terms and conditions of the Intercreditor
Agreement, also may pursue any of the following separately, successively or
simultaneously:

                  (i) require the Pledgor, and the Pledgor hereby agrees that it
      shall at its expense and promptly upon request of the Collateral Agent
      forthwith, assemble all or part of the Collateral as directed by the
      Collateral Agent and make it available to the Collateral Agent at a place
      to be designated by the Collateral Agent that is reasonably convenient to
      both parties; and

                  (ii) without notice except as specified below or under the
      UCC, sell, assign or otherwise dispose of the Collateral or any part
      thereof in one or more parcels at public or private sale, at any of the
      Collateral Agent's offices or elsewhere, for cash, on credit or for future
      delivery, at such time or times and at such price or prices and upon such
      other terms as the Collateral Agent may deem commercially reasonable.

            (b)   The Collateral Agent or any Secured Party may be the purchaser
of any or all of the Collateral at any public or private (to the extent to the
portion of the Collateral being privately sold is of a kind that is customarily
sold on a recognized market or the subject of widely distributed standard price
quotations) sale in accordance with the UCC and the Collateral Agent, as
collateral agent for and representative of the Secured Parties, shall be
entitled, for the purpose of bidding and making settlement or payment of the
purchase price for all or any portion of the Collateral sold at any such sale
made in accordance with the UCC, to use and apply any of the Secured Obligations
as a credit on account of the purchase price for any Collateral payable by the
Collateral Agent at such sale. Each purchaser at any such sale shall hold the
property sold absolutely free from any claim or right on the part of the
Pledgor, and the Pledgor hereby waives (to the extent permitted by applicable
law) all rights of redemption, stay and/or appraisal which it now has or may at
any time in the future have under any rule of law or statute now existing or
hereafter enacted. The Pledgor agrees that, to the extent notice of sale shall
be required by law, at

                                       11

<PAGE>

least ten (10) days notice to the Pledgor of the time and place of any public
sale or the time after which any private sale is to be made shall constitute
reasonable notification. The Collateral Agent shall not be obligated to make any
sale of Collateral regardless of notice of sale having been given. The
Collateral Agent may adjourn any public or private sale from time to time by
announcement at the time and place fixed therefor, and such sale may, without
further notice, be made at the time and place to which it was so adjourned. The
Pledgor hereby waives any claims against the Collateral Agent arising by reason
of the fact that the price at which any Collateral may have been sold at such a
private sale was less than the price which might have been obtained at a public
sale, even if the Collateral Agent accepts the first offer received and does not
offer such Collateral to more than one offeree. Nothing in this Section shall in
any way alter the rights of the Collateral Agent hereunder.

            (c) The Pledgor recognizes that, by reason of certain prohibitions
contained in the Securities Act and applicable state securities laws, the
Collateral Agent may be compelled, with respect to any sale of all or any part
of the Pledged Equity Interests conducted without prior registration or
qualification of such Pledged Equity Interests under the Securities Act and/or
such state securities laws, to limit purchasers to those who will agree, among
other things, to acquire the Pledged Equity Interests for their own account, for
investment and not with a view to the distribution or resale thereof. The
Pledgor acknowledges that any such private sale may be at prices and on terms
less favorable than those obtainable through a public sale without such
restrictions (including a public offering made pursuant to a registration
statement under the Securities Act) and, notwithstanding such circumstances, the
Pledgor agrees that the fact that any such sale is conducted as a private sale
shall not, in and of itself, issue such sale to not be deemed to have been made
in a commercially reasonable manner and that the Collateral Agent shall have no
obligation to engage in public sales and no obligation to delay the sale of any
Pledged Equity Interests for the period of time necessary to permit the issuer
thereof to register it for a form of public sale requiring registration under
the Securities Act or under applicable state securities laws, even if such
issuer would, or should, agree to so register it. If the Collateral Agent
determines to exercise its right to sell any or all of the Pledged Equity
Interests, upon written request, the Pledgor shall and shall cause the Company
to furnish to the Collateral Agent all such information as the Collateral Agent
may request in order to determine the number and nature of interest, shares or
other instruments included in the Pledged Equity Interests which may be sold by
the Collateral Agent in exempt transactions under the Securities Act and the
rules and regulations of the Securities and Exchange Commission thereunder, as
the same are from time to time in effect.

            (d) The Collateral Agent may sell the Collateral without giving any
warranties as to the Collateral. The Collateral Agent may specifically disclaim
or modify any warranties of title or the like. This procedure will not be
considered to adversely affect the commercial reasonableness of any sale of the
Collateral.

            (e) The Collateral Agent shall have no obligation to marshal any of
the Collateral.

      7.2   APPLICATION OF PROCEEDS. Except as expressly provided elsewhere
in this Agreement, all proceeds received by the Collateral Agent in respect of
any sale, any collection from, or other realization upon all or any part of the
Collateral shall be applied in full or in part by the Collateral Agent in
accordance with the Intercreditor Agreement and the Parity Lien Documents.

                                       12

<PAGE>

      7.3   CASH PROCEEDS. All proceeds of any Collateral received by the
Pledgor consisting of cash, checks and other non-cash items (collectively, "CASH
PROCEEDS") shall, if an Event of Default shall have occurred and is continuing
and subject to the terms and conditions of the Intercreditor Agreement, be held
by the Pledgor in trust for the Collateral Agent, segregated from its other
funds, and shall, forthwith upon its receipt, unless otherwise provided pursuant
to Section 4.4(a)(ii) and subject to the terms of the Intercreditor Agreement,
be turned over to the Collateral Agent in the exact form received by the Pledgor
(duly indorsed by the Pledgor to the Collateral Agent, if required) and held by
the Collateral Agent in the Collateral Account. Any Cash Proceeds received by
the Collateral Agent (whether from the Pledgor or otherwise): (i) if no Event of
Default shall have occurred and be continuing, shall be handled as required by
this Agreement or the Parity Lien Documents, or otherwise be turned over to the
Pledgor and (ii) if an Event of Default shall have occurred and be continuing,
may, in the sole discretion of the Collateral Agent while in compliance with the
terms and conditions of the Intercreditor Agreement, (A) be held by the
Collateral Agent for the ratable benefit of the Secured Parties, as collateral
security for the Secured Obligations (whether matured or unmatured) and/or (B)
then or at any time thereafter may be applied by the Collateral Agent against
the Secured Obligations then due and owing in accordance with the Intercreditor
Agreement and the Parity Lien Documents.

SECTION 8. COLLATERAL AGENT.

      The Collateral Agent has been appointed to act as Collateral Agent under
the Parity Lien Documents by the Parity Lien Representatives and, by their
acceptance of the benefits hereof, the other Secured Parties. The Collateral
Agent shall be obligated, and shall have the right hereunder, to make demands,
to give notices, to exercise or refrain from exercising any rights, and to take
or refrain from taking any action (including, without limitation, the release or
substitution of Collateral), solely in accordance with this Agreement, the
Intercreditor Agreement and the Parity Lien Documents; provided, the Collateral
Agent shall, after payment in full of all Obligations under the Parity Lien
Documents, exercise, or refrain from exercising, any remedies provided for
herein in accordance with the instructions of the holders of a majority of the
amount then due and payable (exclusive of expenses and similar payments). In
furtherance of the foregoing provisions of this Section, each Secured Party, by
its acceptance of the benefits hereof, agrees that it shall have no right
individually to realize upon any of the Collateral hereunder, it being
understood and agreed by such Secured Party that all rights and remedies
hereunder may be exercised solely by the Collateral Agent for the benefit of
Secured Parties in accordance with the terms of this Section. Collateral Agent
may resign at any time by giving thirty (30) days' prior written notice thereof
to Parity Lien Representatives and the Pledgor. Upon any such notice of
resignation or any such removal, Required Parity Lien Claimholders shall have
the right, upon five (5) Business Days' notice to the Administrative Agent, to
appoint a successor Collateral Agent. Upon the acceptance of any appointment as
Collateral Agent hereunder by a successor Collateral Agent, that successor
Collateral Agent shall thereupon succeed to and become vested with all the
rights, powers, privileges and duties of the retiring Collateral Agent under
this Agreement, and the retiring Collateral Agent under this Agreement shall
promptly (i) transfer to such successor Collateral Agent all sums, securities
and other items of Collateral held hereunder, together with all records and
other documents necessary or appropriate in connection with the performance of
the duties of the successor Collateral Agent under this Agreement, and (ii)
execute and deliver to such successor Collateral Agent or otherwise authorize
the filing of such amendments to financing statements, and take such other
actions, as may be necessary or appropriate in connection with the assignment to
such successor Collateral Agent of the security interests created hereunder,
whereupon such retiring Collateral Agent shall be discharged from its duties and
obligations under this Agreement. After any retiring Collateral Agent's
resignation hereunder

                                       13

<PAGE>

as the Collateral Agent, the provisions of this Agreement shall inure to its
benefit as to any actions taken or omitted to be taken by it under this
Agreement while it was the Collateral Agent hereunder.

SECTION 9. CONTINUING SECURITY INTEREST; TRANSFER OF LOANS.

      This Agreement shall create a continuing security interest in the
Collateral and shall remain in full force and effect until the payment in full
of all Secured Obligations and the cancellation, cash collateralization or
termination of the Commitments, be binding upon the Pledgor, its successors and
assigns, and inure, together with the rights and remedies of the Collateral
Agent hereunder, to the benefit of the Collateral Agent and its successors,
transferees and assigns. Without limiting the generality of the foregoing, but
subject to the terms of the Parity Lien Documents, any Parity Lien Claimholders
may assign or otherwise transfer any Parity Lien Debt held by it to any other
Person, and such other Person shall thereupon become vested with all the
benefits in respect thereof granted to Parity Lien Claimholders herein or
otherwise. Upon the payment in full of all Secured Obligations and the
cancellation or termination of the Commitments, the security interest granted
hereby shall automatically terminate hereunder and of record and all rights to
the Collateral shall automatically revert to the Pledgor. Upon any such
termination the Collateral Agent shall, at Pledgor's expense, execute and
deliver to the Pledgor such documents as the Pledgor shall reasonably request to
evidence such termination.

SECTION 10. STANDARD OF CARE; COLLATERAL AGENT MAY PERFORM.

      The powers conferred on the Collateral Agent hereunder are solely to
protect its interest in the Collateral and shall not impose any duty upon it to
exercise any such powers. Except for the exercise of reasonable care in the
custody of any Collateral in its possession and the accounting for moneys
actually received by it hereunder, the Collateral Agent shall have no duty as to
any Collateral or as to the taking of any necessary steps to preserve rights
against prior parties or any other rights pertaining to any Collateral. The
Collateral Agent shall be deemed to have exercised reasonable care in the
custody and preservation of Collateral in its possession if such Collateral is
accorded treatment substantially equal to that which the Collateral Agent
accords its own property. Neither the Collateral Agent nor any of its directors,
officers, employees or agents shall be liable for failure to demand, collect or
realize upon all or any part of the Collateral or for any delay in doing so or
shall be under any obligation to sell or otherwise dispose of any Collateral
upon the request of the Pledgor or otherwise. If the Pledgor fails to perform
any agreement contained herein, the Collateral Agent may itself perform, or
cause performance of, such agreement, and the expenses of the Collateral Agent
incurred in connection therewith shall be payable by the Pledgor.

SECTION 11. MISCELLANEOUS.

      Any notice required or permitted to be given under this Agreement shall be
given in accordance with the Parity Lien Documents. No failure or delay on the
part of the Collateral Agent in the exercise of any power, right or privilege
hereunder or under any other Parity Lien Document shall impair such power, right
or privilege or be construed to be a waiver of any default or acquiescence
therein, nor shall any single or partial exercise of any such power, right or
privilege preclude other or further exercise thereof or of any other power,
right or privilege. All rights and remedies existing under this Agreement and
the other Parity Lien Documents are cumulative to, and not exclusive of, any
rights or remedies otherwise available. In case any provision in or obligation
under this Agreement shall be invalid, illegal or unenforceable in any
jurisdiction, the validity, legality and enforceability of the remaining
provisions or obligations, or

                                       14

<PAGE>

of such provision or obligation in any other jurisdiction, shall not in any way
be affected or impaired thereby. All covenants hereunder shall be given
independent effect so that if a particular action or condition is not permitted
by any of such covenants, the fact that it would be permitted by an exception
to, or would otherwise be within the limitations of, another covenant shall not
avoid the occurrence of a Default or an Event of Default if such action is taken
or condition exists. This Agreement shall be binding upon and inure to the
benefit of the Collateral Agent and Pledgors and their respective successors and
assigns. The Pledgor shall not, without the prior written consent of the
Collateral Agent given in accordance with the Parity Lien Documents, assign any
right, duty or obligation hereunder. This Agreement and the other Parity Lien
Documents embody the entire agreement and understanding between the Pledgor and
the Collateral Agent and supersede all prior agreements and understandings
between such parties relating to the subject matter hereof and thereof.
Accordingly, the Parity Lien Documents may not be contradicted by evidence of
prior, contemporaneous or subsequent oral agreements of the parties. There are
no unwritten oral agreements between the parties. This Agreement may be executed
in one or more counterparts and by different parties hereto in separate
counterparts, each of which when so executed and delivered shall be deemed an
original, but all such counterparts together shall constitute but one and the
same instrument; signature pages may be detached from multiple separate
counterparts and attached to a single counterpart so that all signature pages
are physically attached to the same document.

      Notwithstanding anything herein to the contrary, the lien and security
interest granted to the Parity Lien Collateral Agent pursuant to this Agreement
and the exercise of any right or remedy by the Parity Lien Collateral Agent
hereunder are subject to the provisions of the Intercreditor Agreement, dated as
of June 24, 2004 (as amended, restated, supplemented or otherwise modified from
time to time, the "INTERCREDITOR AGREEMENT"), among Covanta Energy Corporation,
Goldman Sachs Credit Partners L.P., as First Lien Collateral Agent, and Credit
Suisse, Cayman Islands Branch, as Parity Lien Collateral Agent, and certain
other persons party or that may become party thereto from time to time. In the
event of any conflict between the terms of the Intercreditor Agreement and this
Agreement, the terms of the Intercreditor Agreement shall govern and control.

            THIS AGREEMENT AND THE RIGHTS AND OBLIGATIONS OF THE PARTIES
HEREUNDER SHALL BE GOVERNED BY, AND SHALL BE CONSTRUED AND ENFORCED IN
ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK.

                                       15

      IN WITNESS WHEREOF, the Pledgor and the Collateral Agent have caused this
Agreement to be duly executed and delivered by their respective officers
thereunto duly authorized as of the date first written above.
