respect to the following Pledged Collateral:

            (a) Instruments and Tangible Chattel Paper. (i) No amounts payable
      under or in connection with any of the Pledged Collateral are evidenced by
      any Instrument or Tangible Chattel Paper other than such Instruments and

      Paper listed in Schedule 11 annexed to the Perfection Certificate has been
      properly endorsed, assigned and delivered to the Collateral Agent,
      accompanied by instruments of transfer or assignment duly executed in
      blank. If any amount then payable under or in connection with any of the
      Pledged Collateral shall be evidenced by any Instrument or Tangible
      Chattel Paper, and such amount, together with all amounts payable
      evidenced by any Instrument or Tangible Chattel Paper not previously
      delivered to the Collateral Agent exceeds $500,000 in the aggregate for
      all Pledgors, the Pledgor acquiring such Instrument or Tangible Chattel
      Paper shall forthwith endorse, assign and deliver the same to the
      Collateral Agent, accompanied by such instruments of transfer or
      assignment duly executed in blank as the Collateral Agent may from time to
      time reasonably specify.

            (b) Deposit Accounts. (i) As of the date hereof each Pledgor has
      neither opened nor maintains any Deposit Accounts other than the accounts
      listed in Schedule 14 annexed to the Perfection Certificate and (ii) from
      and after the date on which a Control Agreement with respect to each
      Deposit Account (other than an Exlcuded Account) is obtained (which date
      shall not be later than 60 days after the Closing Date), the Collateral
      Agent will have a perfected First Priority security interest in each
      Deposit Account (other than an Excluded Account) listed in Schedule 14
      annexed to the Perfection Certificate by Control. No Pledgor shall
      hereafter establish and maintain any Deposit Account (other than an
      Excluded Account) unless (1) the bank shall be reasonably acceptable to
      the Collateral Agent and (2) such bank and such Pledgor shall have duly
      executed and delivered to the Collateral Agent a Deposit Account Control
      Agreement with respect to such Deposit Account. The Collateral Agent
      agrees with each Pledgor that the Collateral Agent shall not give any
      instructions directing the disposition of funds from time to time credited
      to any Deposit Account subject to a Control Agreement or withhold any
      withdrawal rights from such Pledgor with respect to funds from time to
      time credited to any Deposit Account subject to a Control Agreement unless
      an Event of Default has occurred and is continuing. The provisions of this
      Section 3.4(b) shall not apply to the LC Account or to any other Deposit
      Accounts for which the Collateral Agent is the Bank. No Pledgor shall
      grant Control of any Deposit Account to any person other than the
      Collateral Agent.



                                      -14-

            (c) Investment Property. (i) As of the date hereof each Pledgor has
      no Securities Accounts or Commodity Accounts other than those listed in
      Schedule 14 annexed to the Perfection Certificate and the Collateral Agent
      has a perfected First Priority security interest in such Securities
      Accounts and Commodity Accounts by Control. No Pledgor shall hereafter
      establish and maintain any Securities Account or Commodity Account with
      any Securities Intermediary or Commodity Intermediary unless (1) the
      applicable Pledgor shall have given the Collateral Agent prior written
      notice of its intention to establish such new Securities Account or
      Commodity Account with such Securities Intermediary or Commodity
      Intermediary, (2) such Securities Intermediary or Commodity Intermediary
      shall be reasonably acceptable to the Collateral Agent and (3) such
      Securities Intermediary or Commodity Intermediary, as the case may be, and
      such Pledgor shall have duly executed and delivered a Control Agreement
      with respect to such Securities Account or Commodity Account, as the case
      may be. Each Pledgor shall accept any cash and Investment Property in
      trust for the benefit of the Collateral Agent and within five (5) Business
      Days of actual receipt thereof, deposit any and all cash and Investment
      Property (other than any Investment Property pledged pursuant to clauses
      (ii)(1), (iii)(1) or (iii)(3) below) received by it into a Deposit Account
      or Securities Account subject to Collateral Agent's Control. The
      Collateral Agent agrees with each Pledgor that the Collateral Agent shall
      not give any Entitlement Orders or instructions or directions to any
      issuer of uncertificated securities, Securities Intermediary or Commodity
      Intermediary, and shall not withhold its consent to the exercise of any
      withdrawal or dealing rights by such Pledgor, unless an Event of Default
      has occurred and is continuing or, after giving effect to any such
      investment and withdrawal rights, would occur. The provisions of this
      Section 3.4(c) shall not apply to any Financial Assets credited to a
      Securities Account for which the Collateral Agent is the Securities
      Intermediary. No Pledgor shall grant control over any Investment Property
      to any person other than the Collateral Agent.

            (ii) If any Pledgor shall at any time hold or acquire any
      certificated securities constituting Investment Property, such Pledgor
      shall promptly (1) endorse, assign and deliver the same to the Collateral
      Agent, accompanied by such instruments of transfer or assignment duly
      executed in blank, all in form and substance reasonably satisfactory to
      the Collateral Agent or (2) deliver such securities into a Securities
      Account with respect to which a Securities Account Control Agreement is in
      effect in favor of the Collateral Agent.

            (iii) If any securities now or hereafter acquired by any Pledgor
      constituting Investment Property are uncertificated and are issued to such
      Pledgor or its nominee directly by the issuer thereof, such Pledgor shall
      promptly notify the Collateral Agent thereof and pursuant to an agreement
      in form and substance reasonably satisfactory to the Collateral Agent,
      either (1) cause the issuer to agree to comply with instructions from the
      Collateral Agent as to such securities, without further consent of any
      Pledgor or such nominee, (2) cause a Security Entitlement with respect to
      such uncertificated security to be held in a Securities Account with
      respect to which the Collateral Agent has Control or (3) arrange for the
      Collateral Agent to become the registered owner of such securities.



                                      -15-

            (iv) As between the Collateral Agent and the Pledgors, the Pledgors
      shall bear the investment risk with respect to the Investment Property and
      Pledged Securities, and the risk of loss of, damage to, or the destruction
      of the Investment Property and Pledged Securities, whether in the
      possession of, or maintained as a security entitlement or deposit by, or
      subject to the control of, the Collateral Agent, a Securities
      Intermediary, a Commodity Intermediary, any Pledgor or any other person;
      provided, however, that nothing contained in this Section 3.4(c) shall
      release or relieve any Securities Intermediary or Commodity Intermediary
      of its duties and obligations to the Pledgors or any other person under
      any Control Agreement or under applicable law.

            (d) Electronic Chattel Paper and Transferable Records. On the date
      hereof, no amount under or in connection with any of the Pledged
      Collateral is evidenced by any Electronic Chattel Paper or any
      "transferable record" (as that term is defined in Section 201 of the
      Federal Electronic Signatures in Global and National Commerce Act, or in
      Section 16 of the Uniform Electronic Transactions Act as in effect in any
      relevant jurisdiction) other than such Electronic Chattel Paper and
      transferable records listed in Schedule 11 annexed to the Perfection
      Certificate (to the extent required to be listed on the schedules to the
      Perfection Certificate as of the date this representation is made or
      deemed made). If any amount payable under or in connection with any of the
      Pledged Collateral shall be evidenced by any Electronic Chattel Paper or
      any transferable record, the Pledgor acquiring such Electronic Chattel
      Paper or transferable record shall promptly notify the Collateral Agent
      thereof and shall take such action as the Collateral Agent may reasonably
      request to vest in the Collateral Agent control of such Electronic Chattel
      Paper under Section 9-105 of the UCC or control under Section 201 of the
      Federal Electronic Signatures in Global and National Commerce Act or, as
      the case may be, Section 16 of the Uniform Electronic Transactions Act, as
      so in effect in such jurisdiction, of such transferable record. The
      requirement in the preceding sentence shall apply to the extent that such
      amount, together with all amounts payable evidenced by Electronic Chattel
      Paper or any transferable record in which the Collateral Agent has not
      been vested control within the meaning of the statutes described in the
      immediately preceding sentence exceeds $500,000 in the aggregate for all
      Pledgors. The Collateral Agent agrees with such Pledgor that the
      Collateral Agent will arrange, pursuant to procedures satisfactory to the
      Collateral Agent and so long as such procedures will not result in the
      Collateral Agent's loss of control, for the Pledgor to make alterations to
      the Electronic Chattel Paper or transferable record permitted under
      Section 9-105 of the UCC or, as the case may be, Section 201 of the
      Federal Electronic Signatures in Global and National Commerce Act or
      Section 16 of the Uniform Electronic Transactions Act for a party in
      control to allow without loss of control, unless an Event of Default has
      occurred and is continuing or would occur after taking into account any
      action by such Pledgor with respect to such Electronic Chattel Paper or
      transferable record.

            (e) Letter-of-Credit Rights. If any Pledgor is at any time a
      beneficiary under a Letter of Credit now or hereafter issued in favor of
      such Pledgor, other than a Letter of Credit issued pursuant to the Credit
      Agreement, such Pledgor shall promptly notify the Collateral Agent thereof
      and such Pledgor shall, at the request of the Collateral Agent,



                                      -16-

      pursuant to an agreement in form and substance reasonably satisfactory to
      the Collateral Agent, either (i) arrange for the issuer and any confirmer
      of such Letter of Credit to consent to an assignment to the Collateral
      Agent of the proceeds of any drawing under the Letter of Credit or (ii)
      arrange for the Collateral Agent to become the transferee beneficiary of
      such Letter of Credit, with the Collateral Agent agreeing, in each case,
      that the proceeds of any drawing under the Letter of Credit are to be
      applied as provided in the Credit Agreement. The actions in the preceding
      sentence shall be taken to the extent that the amount of such Letter of
      Credit, together with all amounts of all other Letters of Credit, other
      than any Letter of Credit issued pursuant to the Credit Agreement, for
      which the actions described above in clause (i) and (ii) have not been
      taken, exceeds $500,000 in the aggregate for all Pledgors.

            (f) Commercial Tort Claims. As of the date hereof each Pledgor
      hereby represents and warrants that as of the date hereof it holds no
      Commercial Tort Claims other than those listed in Schedule 13 annexed to
      the Perfection Certificate (to the extent required to be listed on the
      schedules to the Perfection Certificate as of the date this representation
      is made or deemed made). If any Pledgor shall at any time hold or acquire
      a Commercial Tort Claim having a value together with all other Commercial
      Tort Claims of all Pledgors in which the Collateral Agent does not have a
      security interest in excess of $500,000 in the aggregate, such Pledgor
      shall immediately notify the Collateral Agent in writing signed by such
      Pledgor of the brief details thereof and grant to the Collateral Agent in
      such writing a security interest therein and in the Proceeds thereof, all
      upon the terms of this Agreement, with such writing to be in form and
      substance reasonably satisfactory to the Collateral Agent.

            (g) Motor Vehicles. Each Pledgor shall comply with Section 6.16 of
      the Credit Agreement with respect to Motor Vehicles owned by such Pledgor
      on the date hereof. With respect to each Motor Vehicle in which ownership
      is acquired by a Pledgor after the date hereof (other than Motor Vehicles
      subject to an agreement of the type specified in clause (d) of the
      definition of "Special Property"), such Pledgor shall deliver to the
      Collateral Agent as soon as practicable after the date of such
      acquisition, originals of the certificates of title or ownership for such
      Motor Vehicles owned by it with the Collateral Agent listed as lienholder
      therein.

            SECTION 3.5. Joinder of Additional Guarantors. The Pledgors shall
cause each Subsidiary of the Borrower which, from time to time, after the date
hereof shall be required to pledge any assets to the Collateral Agent for the
benefit of the Secured Parties pursuant to the provisions of the Credit
Agreement, (a) to execute and deliver to the Collateral Agent (i) a Joinder
Agreement substantially in the form of Exhibit 3 annexed hereto within thirty
(30) days of the date on which it was acquired or created and (ii) a Perfection
Certificate, in each case, within thirty (30) days of the date on which it was
acquired or created or, (b) in the case of a Subsidiary organized outside of the
United States required to pledge any assets to the Collateral Agent, execute and
deliver such documentation as the Collateral Agent shall reasonably request and,
in each case with respect to clauses (a) and (b) above, upon such execution and
delivery, such Subsidiary shall constitute a "Guarantor" and a "Pledgor" for all
purposes hereunder with the same



                                      -17-

force and effect as if originally named as a Guarantor and Pledgor herein. The
execution and delivery of such Joinder Agreement shall not require the consent
of any Pledgor hereunder. The rights and obligations of each Pledgor hereunder
shall remain in full force and effect notwithstanding the addition of any new
Guarantor and Pledgor as a party to this Agreement.

            SECTION 3.6. Supplements; Further Assurances. Each Pledgor shall
take such further actions, and to execute and/or deliver to the Collateral Agent
such additional financing statements, amendments, assignments, agreements,
supplements, powers and instruments, as the Collateral Agent may in its
reasonable judgment deem necessary or appropriate in order to perfect, preserve
and protect the security interest in the Pledged Collateral as provided herein
and the rights and interests granted to the Collateral Agent hereunder, to carry
into effect the purposes hereof or better to assure and confirm unto the
Collateral Agent the Pledged Collateral or permit the Collateral Agent to
exercise and enforce its rights, powers and remedies hereunder with respect to
any Pledged Collateral, including the filing of any financing statements,
continuation statements and other documents (including this Agreement) under the
Uniform Commercial Code (or other similar laws) in effect in any jurisdiction
with respect to the security interest created hereby and the execution and
delivery of Control Agreements with respect to Securities Accounts, Commodities
Accounts and Deposit Accounts (other than Excluded Accounts), all in form
reasonably satisfactory to the Collateral Agent and in such offices (including
the United States Patent and Trademark Office and the United States Copyright
Office) wherever required by law to perfect, continue and maintain a valid,
enforceable, First Priority security interest in the Pledged Collateral as
provided herein and to preserve the other rights and interests granted to the
Collateral Agent hereunder, as against third parties, with respect to the
Pledged Collateral. Without limiting the generality of the foregoing, but
subject to applicable law, each Pledgor shall make, execute, endorse,
acknowledge, file or refile and/or deliver to the Collateral Agent from time to
time upon reasonable request by the Collateral Agent such lists, schedules,
descriptions and designations of the Pledged Collateral, copies of warehouse
receipts, receipts in the nature of warehouse receipts, bills of lading,
documents of title, vouchers, invoices, schedules, confirmatory assignments,
supplements, additional security agreements, conveyances, financing statements,
transfer endorsements, powers of attorney, certificates, reports and other
assurances or instruments as the Collateral Agent shall reasonably request. If
an Event of Default has occurred and is continuing, the Collateral Agent may
institute and maintain, in its own name or in the name of any Pledgor, such
suits and proceedings as the Collateral Agent may be advised by counsel shall be
necessary or expedient to prevent any impairment of the security interest in or
the perfection thereof in the Pledged Collateral. All of the foregoing shall be
at the sole cost and expense of the Pledgors.

                                   ARTICLE IV

                    REPRESENTATIONS, WARRANTIES AND COVENANTS

           Each Pledgor represents, warrants and covenants as follows:



                                      -18-

            SECTION 4.1. Title. Except for the security interest granted to the
Collateral Agent for the ratable benefit of the Secured Parties pursuant to this
Agreement and Permitted Liens, such Pledgor owns and has rights and, as to
Pledged Collateral acquired by it from time to time after the date hereof, will
own and have rights in each item of Pledged Collateral pledged by it hereunder
free and clear of any and all Liens or claims of others.

            SECTION 4.2. Validity of Security Interest. The security interest in
and Lien on the Pledged Collateral granted to the Collateral Agent for the
benefit of the Secured Parties hereunder constitutes (a) a legal and valid
security interest in all the Pledged Collateral securing the payment and
performance of the Secured Obligations, and (b) subject to the filings and other
actions described in Schedule 7 annexed to the Perfection Certificate (to the
extent required to be listed on the schedules to the Perfection Certificate as
of the date this representation is made or deemed made) and subject to notation
of the Collateral Agent's security interest on the applicable certificates of
title with respect to Motor Vehicles and other goods covered by certificate of
title, a perfected security interest in all the Pledged Collateral. The security
interest and Lien granted to the Collateral Agent for the benefit of the Secured
Parties pursuant to this Agreement in and on the Pledged Collateral will at all
times constitute a perfected, continuing security interest therein, prior to all
other Liens on the Pledged Collateral except for Permitted Liens.

            SECTION 4.3. Defense of Claims; Transferability of Pledged
Collateral. Each Pledgor shall, at its own cost and expense, defend title to the
Pledged Collateral pledged by it hereunder and the security interest therein and
Lien thereon granted to the Collateral Agent and the priority thereof against
all claims and demands of all persons, at its own cost and expense, at any time
claiming any interest therein materially adverse to the Collateral Agent or any
other Secured Party other than Permitted Collateral Liens.

            SECTION 4.4. Other Financing Statements. It has not filed, nor
authorized any third party to file (nor will there be any) valid or effective
financing statement (or similar statement, instrument of registration under the
law of any jurisdiction) covering or purporting to cover any interest of any
kind in the Pledged Collateral, except such as have been filed in favor of the
Collateral Agent pursuant to this Agreement or in favor of any holder of a
Permitted Collateral Lien with respect to such Permitted Collateral Lien or
financing statements or public notices relating to the termination statements
attached to the Perfection Certificate. No Pledgor shall execute, authorize or
permit to be filed in any public office any financing statement (or similar
statement or instrument of registration under the law of any jurisdiction)
relating to any Pledged Collateral, except financing statements and other
statements and instruments filed or to be filed in respect of and covering the
security interests granted by such Pledgor to the holder of the Permitted
Collateral Liens.

            SECTION 4.5. Chief Executive Office; Change of Name; Jurisdiction of
Organization. The Collateral Agent may rely on opinions of counsel as to whether
any or all UCC financing statements of the Pledgors need to be amended as a
result of any of the changes described in Section 6.15 of the Credit Agreement.
If any Pledgor fails to provide information to the Collateral Agent about such
changes on a timely basis, the Collateral Agent shall not be liable or
responsible to any party for any failure to maintain a perfected security
interest in such



                                      -19-

Pledgor's property constituting Pledged Collateral, for which the Collateral
Agent needed to have information relating to such changes. The Collateral Agent
shall have no duty to inquire about such changes if any Pledgor does not inform
the Collateral Agent of such changes, the parties acknowledging and agreeing
that it would not be feasible or practical for the Collateral Agent to search
for information on such changes if such information is not provided by any
Pledgor.

            SECTION 4.6. Location of Inventory and Equipment. It shall not move
any Equipment or Inventory, other than an immaterial portion thereof, to any
location outside of the continental United States.

            SECTION 4.7. Due Authorization and Issuance. All of the Pledged
Securities existing on the date hereof have been, and to the extent any Pledged
Securities are hereafter issued, such Pledged Securities will be, upon such
issuance, duly authorized, validly issued and fully paid and non-assessable.
There is no amount or other obligation owing by any Pledgor to any issuer of the
Pledged Securities in exchange for or in connection with the issuance of the
Pledged Securities or any Pledgor's status as a partner or a member of any
issuer of the Pledged Securities.

            SECTION 4.8. Consents, etc. In the event that the Collateral Agent
desires to exercise any remedies, voting or consensual rights or
attorney-in-fact powers set forth in this Agreement and determines it necessary
to obtain any approvals or consents of any Governmental Authority or any other
person therefor, then, upon the reasonable request of the Collateral Agent, such
Pledgor agrees to use its commercially reasonable efforts to assist and aid the
Collateral Agent to obtain as soon as practicable any necessary approvals or
consents for the exercise of any such remedies, rights and powers.

            SECTION 4.9. Pledged Collateral. All information set forth herein,
including the schedules annexed hereto, and all information contained in any
documents, schedules and lists heretofore delivered to any Secured Party,
including the Perfection Certificate and the schedules thereto, in connection
with this Agreement, in each case, relating to the Pledged Collateral, is
accurate and complete in all material respects. The Pledged Collateral described
on the schedules annexed to the Perfection Certificate constitutes all of the
property of such type of Pledged Collateral owned or held by the Pledgors.

            SECTION 4.10. Insurance. In the event that the proceeds of any
insurance claim are paid to any Pledgor after the Collateral Agent has exercised
its right to foreclose during the existence of an Event of Default, such Net
Cash Proceeds shall be held in trust for the benefit of the Collateral Agent and
immediately after receipt thereof shall be paid to the Collateral Agent for
application in accordance with the Credit Agreement.



                                      -20-

                                   ARTICLE V

               CERTAIN PROVISIONS CONCERNING SECURITIES COLLATERAL

            SECTION 5.1. Pledge of Additional Securities Collateral. Each
Pledgor shall, upon obtaining any Pledged Securities or Intercompany Notes in
excess of $500,000 of any person, accept the same in trust for the benefit of
the Collateral Agent and promptly (but in any event within five Business Days
after receipt thereof) deliver to the Collateral Agent a pledge amendment, duly
executed by such Pledgor, in substantially the form of Exhibit 2 annexed hereto
(each, a "Pledge Amendment"), and the certificates and other documents required
under Section 3.1 and Section 3.2 hereof in respect of the additional Pledged
Securities or Intercompany Notes which are to be pledged pursuant to this
Agreement, and confirming the attachment of the Lien hereby created on and in
respect of such additional Pledged Securities or Intercompany Notes. Each
Pledgor hereby authorizes the Collateral Agent to attach each Pledge Amendment
to this Agreement and agrees that all Pledged Securities or Intercompany Notes
listed on any Pledge Amendment delivered to the Collateral Agent shall for all
purposes hereunder be considered Pledged Collateral.

            SECTION 5.2. Voting Rights; Distributions; etc.

            (i) So long as no Event of Default shall have occurred and be
continuing and the Borrowers have not received written notice from the
Collateral Agent stating its intention to exercise its rights and remedies under
Section 5.2(iii):

            (A) Each Pledgor shall be entitled to exercise any and all voting
      and other consensual rights pertaining to the Securities Collateral or any
      part thereof for any purpose not inconsistent with the terms or purposes
      hereof, the Credit Agreement or any other document evidencing the Secured
      Obligations; provided, however, that no Pledgor shall in any event
      exercise such rights in any manner which could reasonably be expected to
      have a Material Adverse Effect.

            (B) Each Pledgor shall be entitled to receive and retain, and to
      utilize free and clear of the Lien hereof, any and all Distributions, but
      only if and to the extent made in accordance with the provisions of the
      Credit Agreement; provided, however, that any and all such Distributions
      consisting of rights or interests in the form of securities shall be
      forthwith delivered to the Collateral Agent to hold as Pledged Collateral
      and shall, if received by any Pledgor, be received in trust for the
      benefit of the Collateral Agent, be segregated from the other property or
      funds of such Pledgor and be forthwith delivered to the Collateral Agent
      as Pledged Collateral in the same form as so received (with any necessary
      endorsement).

            (ii) The Collateral Agent shall be deemed without further action or
formality to have granted to each Pledgor all necessary consents relating to
voting rights and shall, if necessary, upon written request of any Pledgor and
at the sole cost and expense of the



                                      -21-

Pledgors, from time to time execute and deliver (or cause to be executed and
delivered) to such Pledgor all such instruments as such Pledgor may reasonably
request in order to permit such Pledgor to exercise the voting and other rights
which it is entitled to exercise pursuant to Section 5.2(i)(A) hereof and to
receive the Distributions which it is authorized to receive and retain pursuant
to Section 5.2(i)(B) hereof.

            (iii) Upon the occurrence and during the continuance of any Event of
Default and upon receipt by the Borrowers of written notice from the Collateral
Agent stating its intent to exercise its rights and remedies under Section 5.2:

            (A) All rights of each Pledgor to exercise the voting and other
      consensual rights it would otherwise be entitled to exercise pursuant to
      Section 5.2(i)(A) hereof shall immediately cease, and all such rights
      shall thereupon become vested in the Collateral Agent, which shall
      thereupon have the sole right to exercise such voting and other consensual
      rights.

            (B) All rights of each Pledgor to receive Distributions which it
      would otherwise be authorized to receive and retain pursuant to Section
      5.2(i)(B) hereof shall immediately cease and all such rights shall
      thereupon become vested in the Collateral Agent, which shall thereupon
      have the sole right to receive and hold as Pledged Collateral such
      Distributions.

            (iv) Each Pledgor shall, at its sole cost and expense, from time to
time execute and deliver to the Collateral Agent appropriate instruments as the
Collateral Agent may request in order to permit the Collateral Agent to exercise
the voting and other rights which it may be entitled to exercise pursuant to
Section 5.2(iii)(A) hereof and to receive all Distributions which it may be
entitled to receive under Section 5.2(iii)(B) hereof.

            (v) All Distributions which are received by any Pledgor contrary to
the provisions of Section 5.2(i)(B) hereof shall be received in trust for the
benefit of the Collateral Agent, shall be segregated from other funds of such
Pledgor and shall promptly be paid over to the Collateral Agent as Pledged
Collateral in the same form as so received (with any necessary endorsement).

            SECTION 5.3. Defaults, etc. Such Pledgor is not in default in the
payment of any portion of any mandatory capital contribution, if any, required
to be made under any agreement to which such Pledgor is a party relating to the
Pledged Securities pledged by it, and such Pledgor is not in violation of any
other provisions of any such agreement to which such Pledgor is a party, or
otherwise in default or violation thereunder, except any such default or
violation that would not reasonably be expected to result in a Material Adverse
Effect. As of the date hereof, no Securities Collateral pledged by such Pledgor
is subject to any defense, offset or counterclaim, nor have any of the foregoing
been asserted or alleged against such Pledgor by any person with respect
thereto, and as of the date hereof, there are no certificates, instruments,
documents or other writings (other than the Organizational Documents and
certificates representing



                                      -22-

such Pledged Securities, if any, that have been delivered to the Collateral
Agent) which evidence any Pledged Securities of such Pledgor.

            SECTION 5.4. Certain Agreements of Pledgors As Issuers and Holders
of Equity Interests.

            (i) In the case of each Pledgor which is an issuer of Securities
Collateral, such Pledgor agrees to be bound by the terms of this Agreement
relating to the Securities Collateral issued by it and will comply with such
terms insofar as such terms are applicable to it.

            (ii) In the case of each Pledgor which is a partner, shareholder or
member, as the case may be, in a partnership, limited liability company or other
entity, such Pledgor hereby consents to the extent required by the applicable
Organizational Document to the pledge by each other Pledgor, pursuant to the
terms hereof, of the Pledged Securities in such partnership, limited liability
company or other entity and, upon the occurrence and during the continuance of
an Event of Default, to the transfer of such Pledged Securities to the
Collateral Agent or its nominee and to the substitution of the Collateral Agent
or its nominee as a substituted partner, shareholder or member in such
partnership, limited liability company or other entity with all the rights,
powers and duties of a general partner, limited partner, shareholder or member,

                                   ARTICLE VI

                   CERTAIN PROVISIONS CONCERNING INTELLECTUAL
                               PROPERTY COLLATERAL

            SECTION 6.1. Grant of Intellectual Property License. For the purpose
of enabling the Collateral Agent, during the continuance of an Event of Default,
to exercise rights and remedies under Article IX hereof at such time as the
Collateral Agent shall be lawfully entitled to exercise such rights and
remedies, and for no other purpose, each Pledgor hereby grants to the Collateral
Agent, to the extent assignable and effective only during the continuance of an
Event of Default, an irrevocable, non-exclusive license to use, assign, license
or sublicense any of the Intellectual Property Collateral now owned or hereafter
acquired by such Pledgor, wherever the same may be located. Such license shall
include access to all media in which any of the licensed items may be recorded
or stored and to all computer programs used for the compilation or printout
hereof.

            SECTION 6.2. Protection of Collateral Agent's Security. On a
continuing basis, each Pledgor shall, at its sole cost and expense, (i) promptly
following its becoming aware thereof, notify the Collateral Agent of any
materially adverse determination in any proceeding or the institution of any
proceeding in any federal, state or local court or administrative body or in the
United States Patent and Trademark Office or the United States Copyright Office
regarding such Pledgor's claim of ownership in or right to use any of the
Intellectual Property Collateral material to the use and operation of the
Pledged Collateral or Mortgaged Property, such



                                      -23-

Pledgor's right to register such Intellectual Property Collateral or its right
to keep and maintain such registration in full force and effect, (ii) maintain
and protect the Intellectual Property Collateral material to the use and
operation of the Pledged Collateral or Mortgaged Property as presently used and
operated and as contemplated by the Credit Agreement, (iii) not permit to lapse
or become abandoned any Intellectual Property Collateral material to the use and
operation of the Pledged Collateral or Mortgaged Property as presently used and
operated and as contemplated by the Credit Agreement, and not settle or
compromise any pending or future litigation or administrative proceeding with
respect to such Intellectual Property Collateral, in each case except as shall
be consistent with commercially reasonable business judgment, (iv) upon such
Pledgor obtaining knowledge thereof, promptly notify the Collateral Agent in
writing of any event which may be reasonably expected to materially and
adversely affect the value or utility of any of the Intellectual Property
Collateral or any portion thereof that is material to the use and operation of
the Pledged Collateral or Mortgaged Property or the rights and remedies of the
Collateral Agent in relation thereto including a levy or threat of levy or any
legal process against the Intellectual Property Collateral or any portion
thereof, (v) not license the Intellectual Property Collateral other than
licenses entered into by such Pledgor in, or incidental to, the ordinary course
of business, or amend or permit the amendment of any of the licenses in a manner
that materially and adversely affects the right to receive payments thereunder,
or in any manner that would materially impair the value of the Intellectual
Property Collateral or the Lien on and security interest in the Intellectual
Property Collateral created therein hereby, without the consent of the
Collateral Agent (which shall not be unreasonably delayed or withheld), (vi)
diligently keep adequate records respecting its material Intellectual Property
Collateral and (vii) furnish to the Collateral Agent from time to time upon the
Collateral Agent's reasonable request therefor reasonably detailed statements
and amended schedules further identifying and describing the Intellectual
Property Collateral and such other materials evidencing or reports pertaining to
the Intellectual Property Collateral as the Collateral Agent may from time to
time reasonably request.

            SECTION 6.3. After-Acquired Property. If any Pledgor shall at any
time after the date hereof (i) obtain any rights to any additional Intellectual
Property Collateral or (ii) become entitled to the benefit of any additional
Intellectual Property Collateral or any renewal or extension thereof, including
any reissue, division, continuation, or continuation-in-part of any Intellectual
Property Collateral, or any improvement on any Intellectual Property Collateral,
the provisions hereof shall automatically apply thereto and any such item
enumerated in clause (i) or (ii) of this Section 6.3 with respect to such
Pledgor shall automatically constitute Intellectual Property Collateral as if
such would have constituted Intellectual Property Collateral at the time of
execution hereof and be subject to the Lien and security interest created by
this Agreement without further action by any party. Each Pledgor shall promptly
with the delivery of its quarterly financial statements (i) provide to the
Collateral Agent written notice of any of the foregoing and (ii) confirm the
attachment of the Lien and security interest created by this Agreement to any
rights described in clauses (i) and (ii) of the immediately preceding sentence
of this Section 6.3 by execution of an instrument in form reasonably acceptable
to the Collateral Agent and the filing of any instruments or statements as shall
be reasonably necessary to preserve, protect or perfect the Collateral Agent's
security interest in such Intellectual Property Collateral. Further, each
Pledgor authorizes the Collateral Agent to modify this Agreement by



                                      -24-

amending Schedules 12(a) and 12(b) annexed to the Perfection Certificate to
include any Intellectual Property Collateral of such Pledgor acquired or arising
after the date hereof.

            SECTION 6.4. Litigation. Unless there shall occur and be continuing
any Event of Default and the Borrowers receive written notice from the
Collateral Agent of its intent to exercise remedies hereunder, each Pledgor
shall have the right to commence and prosecute in its own name, as the party in
interest, for its own benefit and at the sole cost and expense of the Pledgors,
such applications for protection of the Intellectual Property Collateral and
suits, proceedings or other actions to prevent the infringement, counterfeiting,
unfair competition, dilution, diminution in value or other damage as are
necessary to protect the Intellectual Property Collateral. Upon the occurrence
and during the continuance of any Event of Default and upon receipt by the
Borrower of written notice from the Collateral Agent stating its intent to
exercise remedies hereunder, the Collateral Agent shall have the right but shall
in no way be obligated to file applications for protection of the Intellectual
Property Collateral and/or bring suit in the name of any Pledgor, the Collateral
Agent or the Secured Parties to enforce the Intellectual Property Collateral and
any license thereunder. In the event of such suit, each Pledgor shall, at the
reasonable request of the Collateral Agent, do any and all commercially
reasonable acts and execute any and all documents reasonably requested by the
Collateral Agent in aid of such enforcement and the Pledgors shall promptly
reimburse and indemnify the Collateral Agent for all reasonable costs and
expenses incurred by the Collateral Agent in the exercise of its rights under
this Section 6.4 in accordance with Section 10.04 of the Credit Agreement.

                                  ARTICLE VII

                    CERTAIN PROVISIONS CONCERNING RECEIVABLES

            SECTION 7.1. Maintenance of Records. Each Pledgor shall keep and
maintain at its own cost and expense complete records of each Receivable, in a
manner consistent with prudent business practice, including records of all
payments received, all credits granted thereon, all merchandise returned and all
other documentation relating thereto. Each Pledgor shall, at such Pledgor's sole
cost and expense, upon the Collateral Agent's demand made at any time after the
occurrence and during the continuance of any Event of Default, deliver copies of
all tangible evidence of Receivables, including copies of all documents
evidencing Receivables and any books and records relating thereto to the
Collateral Agent or to its representatives.

                                  ARTICLE VIII

                                    TRANSFERS

            SECTION 8.1. Transfers of Pledged Collateral. No Pledgor shall sell,
convey, assign or otherwise dispose of, or grant any option with respect to, any
of the Pledged Collateral pledged by it hereunder except as permitted by the
Credit Agreement.



                                      -25-

                                   ARTICLE IX

                                    REMEDIES

            SECTION 9.1. Remedies. Upon the occurrence and during the
continuance of any Event of Default the Collateral Agent may, subject to the
Retained Rights of any Pledgor, from time to time exercise in respect of the
Pledged Collateral, in addition to the other rights and remedies provided for
herein or otherwise available to it, the following remedies:

            (i) Personally, or by agents or attorneys, immediately take
      possession of the Pledged Collateral or any part thereof, from any Pledgor
      or any other person who then has possession of any part thereof with or
      without notice or process of law, and for that purpose may enter upon any
      Pledgor's premises where any of the Pledged Collateral is located, remove
      such Pledged Collateral, remain present at such premises to receive copies
      of all communications and remittances relating to the Pledged Collateral
      and use in connection with such removal and possession any and all
      services, supplies, aids and other facilities of any Pledgor;

            (ii) Demand, sue for, collect or receive any money or property at
      any time payable or receivable in respect of the Pledged Collateral
      including instructing the obligor or obligors on any agreement, instrument
      or other obligation constituting part of the Pledged Collateral to make
      any payment required by the terms of such agreement, instrument or other
      obligation directly to the Collateral Agent, and in connection with any of
      the foregoing, compromise, settle, extend the time for payment and make
      other modifications with respect thereto; provided, however, that in the
      event that any such payments are made directly to any Pledgor, prior to
      receipt by any such obligor of such instruction, such Pledgor shall
      segregate all amounts received pursuant thereto, hold such amounts in
      trust for the benefit of the Collateral Agent and shall promptly (but in
      no event later than one (1) Business Day after receipt thereof) pay such
      amounts to the Collateral Agent;

            (iii) Sell, assign, grant a license to use or otherwise liquidate,
      or direct any Pledgor to sell, assign, grant a license to use or otherwise
      liquidate, any and all investments made in whole or in part with the
      Pledged Collateral or any part thereof, and take possession of the
      proceeds of any such sale, assignment, license or liquidation;

            (iv) Take possession of the Pledged Collateral or any part thereof,
      by directing any Pledgor in writing to deliver the same to the Collateral
      Agent at any place or places so designated by the Collateral Agent, in
      which event such Pledgor shall at its own expense: (A) forthwith cause the
      same to be moved to the place or places designated by the Collateral Agent
      and therewith delivered to the Collateral Agent, (B) store and keep any
      Pledged Collateral so delivered to the Collateral Agent at such place or
      places pending further action by the Collateral Agent and (C) while the
      Pledged Collateral shall be so stored and kept, provide such security and
      maintenance services as shall be necessary to protect the same and to
      preserve and maintain them in good condition. Each Pledgor's



                                      -26-

      obligation to deliver the Pledged Collateral as contemplated in this
      Section 9.1(iv) is of the essence hereof. Upon application to a court of
      equity having jurisdiction, the Collateral Agent shall be entitled to a
      decree requiring specific performance by any Pledgor of such obligation;

            (v) Withdraw all moneys, instruments, securities and other property
      in any bank, financial securities, deposit or other account of any Pledgor
      constituting Pledged Collateral for application to the Secured Obligations
      as provided in Article X hereof;

            (vi) Following written notice from the Collateral Agent to the
      Borrowers in accordance with Section 5.2(iii), retain and apply the
      Distributions to the Secured Obligations as provided in Article X hereof;

            (vii) Following written notice from the Collateral Agent to the
      Borrowers in accordance with Section 5.2(iii), exercise any and all
      voting, consensual and other rights and powers with respect to any Pledged
      Collateral; and without the requirement of such notice, exercise any and
      all other rights as beneficial and legal owner of the Pledged Collateral,
      including perfecting assignment thereof;

            (viii) Exercise all the rights and remedies of a secured party on
      default under the UCC, and the Collateral Agent may also in its sole
      discretion, without notice except as specified in Section 9.2 hereof,
      sell, assign or grant a license to use the Pledged Collateral or any part
      thereof in one or more parcels at public or private sale, at any exchange,
      broker's board or at any of the Collateral Agent's offices or elsewhere,
      for cash, on credit or for future delivery, and at such price or prices
      and upon such other terms as the Collateral Agent may deem commercially
      reasonable. The Collateral Agent or any other Secured Party or any of
      their respective Affiliates may be the purchaser, licensee, assignee or
      recipient of the Pledged Collateral or any part thereof at any such sale
      and shall be entitled, for the purpose of bidding and making settlement or
      payment of the purchase price for all or any portion of the Pledged
      Collateral sold, assigned or licensed at such sale, to use and apply any
      of the Secured Obligations owed to such person as a credit on account of
      the purchase price of the Pledged Collateral or any part thereof payable
      by such person at such sale. Each purchaser, assignee, licensee or
      recipient at any such sale shall acquire the property sold, assigned or
      licensed absolutely free from any claim or right on the part of any
      Pledgor, and each Pledgor hereby waives, to the fullest extent permitted
      by 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 Collateral Agent shall not be obligated
      to make any sale of the Pledged Collateral or any part thereof 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. Each Pledgor hereby
      waives, to the fullest extent permitted by law, any claims against the
      Collateral Agent arising by reason of the fact that the price at which the
      Pledged Collateral or any part thereof may have been sold, assigned or
      licensed at such a private sale was less than the price which might have
      been obtained at a



                                      -27-

      public sale, even if the Collateral Agent accepts the first offer received
      and does not offer such Pledged Collateral to more than one offeree.

            SECTION 9.2. Notice of Sale. Each Pledgor acknowledges and agrees
that, to the extent notice of sale or other disposition of the Pledged
Collateral or any part thereof shall be required by law, ten (10) days' prior
notice to such Pledgor of the time and place of any public sale or of the time
after which any private sale or other intended disposition is to take place
shall be commercially reasonable notification of such matters. No notification
need be given to any Pledgor if it has signed, during the existence of an Event
of Default, a statement renouncing or modifying any right to notification of
sale or other intended disposition.

            SECTION 9.3. Waiver of Notice and Claims. Each Pledgor hereby
waives, to the fullest extent permitted by applicable law, notice or judicial
hearing in connection with the Collateral Agent's taking possession or the
Collateral Agent's disposition of the Pledged Collateral or any part thereof,
including any and all prior notice and hearing for any prejudgment remedy or
remedies and any such right which such Pledgor would otherwise have under law,
and each Pledgor hereby further waives, to the fullest extent permitted by
applicable law: (i) all damages occasioned by such taking of possession, (ii)
all other requirements as to the time, place and terms of sale or other
requirements with respect to the enforcement of the Collateral Agent's rights
hereunder and (iii) all rights of redemption, appraisal, valuation, stay,
extension or moratorium now or hereafter in force under any applicable law. The
Collateral Agent shall not be liable for any incorrect or improper payment made
pursuant to this Article IX in the absence of gross negligence or willful
misconduct on the part of the Collateral Agent. Any sale of, or the grant of
options to purchase, or any other realization upon, any Pledged Collateral shall
operate to divest all right, title, interest, claim and demand, either at law or
in equity, of the applicable Pledgor therein and thereto, and shall be a
perpetual bar both at law and in equity against such Pledgor and against any and
all persons claiming or attempting to claim the Pledged Collateral so sold,
optioned or realized upon, or any part thereof, from, through or under such
Pledgor.

            SECTION 9.4. Certain Sales of Pledged Collateral.

            (i) Each Pledgor recognizes that, by reason of certain prohibitions
contained in law, rules, regulations or orders of any Governmental Authority,
the Collateral Agent may be compelled, with respect to any sale of all or any
part of the Pledged Collateral, to limit purchasers to those who meet the
requirements of such Governmental Authority. Each Pledgor acknowledges that any
such sales may be at prices and on terms less favorable to the Collateral Agent
than those obtainable through a public sale without such restrictions, and,
notwithstanding such circumstances, agrees that any such restricted sale shall
be deemed to have been made in a commercially reasonable manner and that, except
as may be required by applicable law, the Collateral Agent shall have no
obligation to engage in public sales.

            (ii) Each 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 Securities Collateral and Investment Property, to limit purchasers to
persons who will agree, among other things, to acquire such



                                      -28-

Securities Collateral or Investment Property for their own account, for
investment and not with a view to the distribution or resale thereof. Each
Pledgor acknowledges that any such private sales may be at prices and on terms
less favorable to the Collateral Agent 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, agrees that any such private sale shall 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 Securities Collateral or Investment Property 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 agree to do so.

            (iii) If the Collateral Agent determines to exercise its right to
sell any or all of the Securities Collateral or Investment Property, upon
written request, the applicable Pledgor shall from time to time furnish to the
Collateral Agent all such information as the Collateral Agent may reasonably
request in order to determine the number of securities included in the
Securities Collateral or Investment Property which may be sold by the Collateral
Agent as exempt transactions under the Securities Act and the rules of the
Securities and Exchange Commission thereunder, as the same are from time to time
in effect.

            SECTION 9.5. No Waiver; Cumulative Remedies.

            (i) No failure on the part of the Collateral Agent to exercise, no
course of dealing with respect to, and no delay on the part of the Collateral
Agent in exercising, any right, power or remedy hereunder shall operate as a
waiver thereof; nor shall any single or partial exercise of any such right,
power, privilege or remedy hereunder preclude any other or further exercise
thereof or the exercise of any other right, power, privilege or remedy; nor
shall the Collateral Agent be required to look first to, enforce or exhaust any
other security, collateral or guaranties. All rights and remedies herein
provided are cumulative and are not exclusive of any rights or remedies provided
by law.

            (ii) In the event that the Collateral Agent shall have instituted
any proceeding to enforce any right, power, privilege or remedy under this
Agreement or any other Loan Document by foreclosure, sale, entry or otherwise,
and such proceeding shall have been discontinued or abandoned for any reason or
shall have been determined adversely to the Collateral Agent, then and in every
such case, the Pledgors, the Collateral Agent and each other Secured Party shall
be restored to their respective former positions and rights hereunder with
respect to the Pledged Collateral, and all rights, remedies, privileges and
powers of the Collateral Agent and the other Secured Parties shall continue as
if no such proceeding had been instituted.

            SECTION 9.6. Certain Additional Actions Regarding Intellectual
Property. If any Event of Default shall have occurred and be continuing, upon
the written demand of the Collateral Agent, each Pledgor shall execute and
deliver to the Collateral Agent an assignment or assignments of the registered
Patents, Trademarks and/or Copyrights and Goodwill and such other documents as
are necessary or appropriate to carry out the intent and purposes hereof.

                            APPLICATION OF PROCEEDS

            SECTION 10.1. Application of Proceeds. The proceeds received by the
Collateral Agent in respect of any sale of, collection from or other realization
upon all or any part of the Pledged Collateral pursuant to the exercise by the
Collateral Agent of its remedies shall be applied, together with any other sums
then held by the Collateral Agent pursuant to this Agreement, in accordance with
the Credit Agreement.

                                   ARTICLE XI

                                  MISCELLANEOUS

            SECTION 11.1. Concerning Collateral Agent.

            (i) The Collateral Agent has been appointed as collateral agent
pursuant to the Credit Agreement. The actions of the Collateral Agent hereunder
are subject to the provisions of the Credit Agreement. The Collateral Agent
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 action
(including the release or substitution of the Pledged Collateral), in accordance
with this Agreement and the Credit Agreement. The Collateral Agent may employ
agents and attorneys-in-fact in connection herewith and shall not be liable for
the negligence of any such agents or attorneys-in-fact selected by it in good
faith, but shall be liable for the gross negligence or willful misconduct of
such agents and attorneys-in-fact. The Collateral Agent may resign and a
successor Collateral Agent may be appointed in the manner provided in the Credit
Agreement. Upon the acceptance of any appointment as the Collateral Agent 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 shall thereupon be discharged from its duties and obligations
under this Agreement. After any retiring Collateral Agent's resignation, the
provisions hereof 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.

            (ii) The Collateral Agent shall be deemed to have exercised
reasonable care in the custody and preservation of the Pledged Collateral in its
possession if such Pledged Collateral is accorded treatment substantially
equivalent to that which the Collateral Agent, in its individual capacity,
accords its own property consisting of similar instruments or interests, it
being understood that neither the Collateral Agent nor any of the Secured
Parties shall have responsibility for (i) ascertaining or taking action with
respect to calls, conversions, exchanges, maturities, tenders or other matters
relating to any Securities Collateral, whether or not the Collateral Agent or
any other Secured Party has or is deemed to have knowledge of such matters or
(ii) taking



                                      -30-

any necessary steps to preserve rights against any person with respect to any
Pledged Collateral.

            (iii) The Collateral Agent shall be entitled to rely upon any
written notice, statement, certificate, order or other document or any telephone
message believed by it to be genuine and correct and to have been signed, sent
or made by the proper person, and, with respect to all matters pertaining to
this Agreement and its duties hereunder, upon advice of counsel selected by it.

            (iv) If any item of Pledged Collateral also constitutes collateral
granted to the Collateral Agent under any other deed of trust, mortgage,
security agreement, pledge or instrument of any type, in the event of any
conflict between the provisions hereof and the provisions of such other deed of
trust, mortgage, security agreement, pledge or instrument of any type in respect
of such collateral, the Collateral Agent, in its sole discretion, shall select
which provision or provisions shall control.

            SECTION 11.2. Collateral Agent May Perform; Collateral Agent
Appointed Attorney-in-Fact. If any Pledgor shall fail to perform any covenants
contained in this Agreement or if any representation or warranty on the part of
any Pledgor contained herein shall be breached, the Collateral Agent may (but
shall not be obligated to) during the existence of an Event of Default do the
same or cause it to be done or remedy any such breach, and may expend funds for
such purpose; provided, however, that the Collateral Agent shall in no event be
bound to inquire into the validity of any tax, Lien, imposition or other
obligation which such Pledgor fails to pay or perform as and when required
hereby and which such Pledgor does not contest in accordance with the provisions
of the Credit Agreement. Any and all amounts so expended by the Collateral Agent
shall be paid by the Pledgors in accordance with the provisions of Section 10.04
of the Credit Agreement. Neither the provisions of this Section 11.2 nor any
action taken by the Collateral Agent pursuant to the provisions of this Section
11.2 shall prevent any such failure to observe any covenant contained in this
Agreement nor any breach of representation or warranty from constituting an
Event of Default. Each Pledgor hereby appoints the Collateral Agent its
attorney-in-fact, with full power and authority in the place and stead of such
Pledgor and in the name of such Pledgor, or otherwise, from time to time during
the existence of an Event of Default in the Collateral Agent's discretion to
take any action and to execute any instrument consistent with the terms of the
Credit Agreement, this Agreement and the other Security Documents which the
Collateral Agent may deem necessary or advisable to accomplish the purposes
hereof (but the Collateral Agent shall not be obligated to and shall have no
liability to such Pledgor or any third party for failure to so do or take
action). The foregoing grant of authority is a power of attorney coupled with an
interest and such appointment shall be irrevocable for the term hereof. Each
Pledgor hereby ratifies all that such attorney shall lawfully do or cause to be
done by virtue hereof.

            SECTION 11.3. Continuing Security Interest; Assignment. This
Agreement shall create a continuing security interest in the Pledged Collateral
and shall (i) be binding upon the Pledgors, their respective successors and
assigns and (ii) inure, together with the rights and remedies of the Collateral
Agent hereunder, to the benefit of the Collateral Agent and the other



                                      -31-

Secured Parties and each of their respective permitted successors, transferees
and assigns. No other persons (including any other creditor of any Pledgor)
shall have any interest herein or any right or benefit with respect hereto.
Without limiting the generality of the foregoing clause (ii), any Secured Party
may assign or otherwise transfer any indebtedness held by it secured by this
Agreement to any other person, and such other person shall thereupon become
vested with all the benefits in respect thereof granted to such Secured Party,
herein or otherwise, subject however, to the provisions of the Credit Agreement
and, in the case of a Secured Party that is a party to a Swap Contract, such
Swap Contract.

            SECTION 11.4. Termination; Release. (a)When all the Secured
Obligations have been paid in full (other than contingent indemnification
obligations in which no claim has been made) and the Commitments of the Lenders
to make any Loan or to issue any Letter of Credit under the Credit Agreement
shall have expired or been sooner terminated and all Letters of Credit have been
terminated or collateralized in accordance with the provisions of the Credit
Agreement, this Agreement shall terminate. Upon termination of this Agreement
the Pledged Collateral shall be released from the Lien of this Agreement. Upon
such release or any release of Pledged Collateral or any part thereof in
accordance with the provisions of the Credit Agreement, the Collateral Agent
shall, upon the request and at the sole cost and expense of the Pledgors,
assign, transfer and deliver to Pledgor, against receipt and without recourse to
or warranty by the Collateral Agent except as to the fact that the Collateral
Agent has not encumbered the released assets, such of the Pledged Collateral or
any part thereof to be released (in the case of a release) as may be in
possession of the Collateral Agent and as shall not have been sold or otherwise
applied pursuant to the terms hereof, and, with respect to any other Pledged
Collateral, proper documents and instruments (including UCC-3 termination
financing statements or releases) acknowledging the termination hereof or the
release of such Pledged Collateral, as the case may be.

            (b) Notwithstanding the foregoing, if (i) the Obligations have been
paid in full and the Commitments of the Lenders to make any Loan or to issue any
Letter of Credit under the Credit Agreement shall have expired or been sooner
terminated and all Letters of Credit have been terminated or collateralized in
accordance with the provisions of the Credit Agreement, (ii) Secured Obligations
of the type described in clause (b) of the definition of Secured Obligations
("Remaining Secured Obligations") remain outstanding and (iii) all or a portion
of the repayment of the Obligations is financed by the proceeds of Indebtedness
of one or more Loan Parties or any affiliate of a Loan Party ("Refinancing
Indebtedness") which Refinancing Indebtedness is secured by property of such
persons, this Agreement shall terminate as if the Remaining Secured Obligations
have been paid in full and the provisions of paragraph (a) of this Section 11.4
shall apply concurrently with the incurrence of the Refinancing Indebtedness and
the securing of the Refinancing Indebtedness and the Remaining Secured
Obligations on an equal and ratable basis. For the avoidance of doubt, if the
Refinancing Indebtedness is not secured, this Agreement shall not terminate but
shall remain in full force and effect.

            (c) If any Collateral shall be sold, transferred or otherwise
disposed of by any Pledgor in a transaction permitted by the Credit Agreement,
then the Collateral Agent, at the sole



                                      -32-

expense of such Pledgor, shall execute and deliver to such Pledgor all releases
or other documents necessary or desirable for the release of the Liens created
hereby on such Collateral.

            SECTION 11.5. Modification in Writing. No amendment, modification,
supplement, termination or waiver of or to any provision hereof, nor consent to
any departure by any Pledgor therefrom, shall be effective unless the same shall
be made in accordance with the terms of the Credit Agreement and unless in
writing and signed by the Collateral Agent. Any amendment, modification or
supplement of or to any provision hereof, any waiver of any provision hereof and
any consent to any departure by any Pledgor from the terms of any provision
hereof in each case shall be effective only in the specific instance and for the
specific purpose for which made or given. Except where notice is specifically
required by this Agreement or any other document evidencing the Secured
Obligations, no notice to or demand on any Pledgor in any case shall entitle any
Pledgor to any other or further notice or demand in similar or other
circumstances.

            SECTION 11.6. Notices. Unless otherwise provided herein or in the
Credit Agreement, any notice or other communication herein required or permitted
to be given shall be given in the manner and become effective as set forth in
the Credit Agreement, as to any Pledgor, addressed to it at the address of the
Borrower set forth in the Credit Agreement and as to the Collateral Agent,
addressed to it at the address set forth in the Credit Agreement, or in each
case at such other address as shall be designated by such party in a written
notice to the other party complying as to delivery with the terms of this
Section 11.6.

            SECTION 11.7. Governing Law, Consent to Jurisdiction and Service of
Process; Waiver of Jury Trial. Sections 10.14 and 10.15 of the Credit Agreement
are incorporated herein, mutatis mutandis, as if a part hereof.

            SECTION 11.8. Severability of Provisions. Any provision hereof which
is invalid, illegal or unenforceable in any jurisdiction shall, as to such
jurisdiction, be ineffective to the extent of such invalidity, illegality or
unenforceability without invalidating the remaining provisions hereof or
affecting the validity, legality or enforceability of such provision in any
other jurisdiction.

            SECTION 11.9. Execution in Counterparts. This Agreement and any
amendments, waivers, consents or supplements hereto may be executed in any
number of counterparts and by different parties hereto in separate counterparts,
each of which when so executed and delivered shall be deemed to be an original,
but all such counterparts together shall constitute one and the same agreement.

            SECTION 11.10. Business Days. In the event any time period or any
date provided in this Agreement ends or falls on a day other than a Business
Day, then such time period shall be deemed to end and such date shall be deemed
to fall on the next succeeding Business Day, and performance herein may be made
on such Business Day, with the same force and effect as if made on such other
day.



                                      -33-

            SECTION 11.11. No Credit for Payment of Taxes or Imposition. Such
Pledgor shall not be entitled to any credit against the principal, premium, if
any, or interest payable under the Credit Agreement, and such Pledgor shall not
be entitled to any credit against any other sums which may become payable under
the terms thereof or hereof, by reason of the payment of any Tax on the Pledged
Collateral or any part thereof.

            SECTION 11.12. No Claims Against Collateral Agent. Nothing contained
in this Agreement shall constitute any consent or request by the Collateral
Agent, express or implied, for the performance of any labor or services or the
furnishing of any materials or other property in respect of the Pledged
Collateral or any part thereof, nor as giving any Pledgor any right, power or
authority to contract for or permit the performance of any labor or services or
the furnishing of any materials or other property in such fashion as would
permit the making of any claim against the Collateral Agent in respect thereof
or any claim that any Lien based on the performance of such labor or services or
the furnishing of any such materials or other property is prior to the Lien
hereof.

            SECTION 11.13. No Release. Nothing set forth in this Agreement or
any other Loan Document, nor the exercise by the Collateral Agent of any of the
rights or remedies hereunder, shall relieve any Pledgor from the performance of
any term, covenant, condition or agreement on such Pledgor's part to be
performed or observed under or in respect of any of the Pledged Collateral or
from any liability to any person under or in respect of any of the Pledged
Collateral or shall impose any obligation on the Collateral Agent or any other
Secured Party to perform or observe any such term, covenant, condition or
agreement on such Pledgor's part to be so performed or observed or shall impose
any liability on the Collateral Agent or any other Secured Party for any act or
omission on the part of such Pledgor relating thereto or for any breach of any
representation or warranty on the part of such Pledgor contained in this
Agreement, the Credit Agreement or the other Loan Documents, or under or in
respect of the Pledged Collateral or made in connection herewith or therewith.
Anything herein to the contrary notwithstanding, neither the Collateral Agent
nor any other Secured Party shall have any obligation or liability under any
contracts, agreements and other documents included in the Pledged Collateral by
reason of this Agreement, nor shall the Collateral Agent or any other Secured
Party be obligated to perform any of the obligations or duties of any Pledgor
thereunder or to take any action to collect or enforce any such contract,
agreement or other document included in the Pledged Collateral hereunder. The
obligations of each Pledgor contained in this Section 11.13 shall survive the
termination hereof and the discharge of such Pledgor's other obligations under
this Agreement, the Credit Agreement and the other Loan Documents.

            SECTION 11.14. Obligations Absolute. All obligations of each Pledgor
hereunder shall be absolute and unconditional irrespective of:

            (i) any bankruptcy, insolvency, reorganization, arrangement,
      readjustment, composition, liquidation or the like of any other Pledgor;



                                      -34-

            (ii) any lack of validity or enforceability of the Credit Agreement,
      any Swap Contract or any other Loan Document, or any other agreement or
      instrument relating thereto;

            (iii) any change in the time, manner or place of payment of, or in
      any other term of, all or any of the Secured Obligations, or any other
      amendment or waiver of or any consent to any departure from the Credit
      Agreement, any Swap Contract or any other Loan Document or any other
      agreement or instrument relating thereto;

            (iv) any pledge, exchange, release or non-perfection of any other
      collateral, or any release or amendment or waiver of or consent to any
      departure from any guarantee, for all or any of the Secured Obligations;

            (v) any exercise, non-exercise or waiver of any right, remedy, power
      or privilege under or in respect hereof, the Credit Agreement, any Swap
      Contract or any other Loan Document except as specifically set forth in a
      waiver granted pursuant to the provisions of Section 11.5 hereof; or

            (vi) any other circumstances which might otherwise constitute a
      defense available to, or a discharge of, any Pledgor.

Ladies and Gentlemen:

            Reference is made to the Security Agreement (as amended, amended and
restated, supplemented or otherwise modified from time to time, the "Security
Agreement;" capitalized terms used but not otherwise defined herein shall have
the meanings assigned to such terms in the Security Agreement), dated as of
February 10, 2005 made by AMR HOLDCO, INC., a Delaware corporation ("AMR
Holdco"), and EMCARE HOLDCO, INC., a Delaware corporation ("EmCare Holdco")
(each of AMR Holdco and EmCare Holdco, a "Borrower" and, together, the
"Borrowers") and THE GUARANTORS party thereto and BANK OF AMERICA, N.A., as
collateral agent (in such capacity and together with any successors in such
capacity, the "Collateral Agent").

            This Joinder Agreement supplements the Security Agreement and is
delivered by the undersigned, [    ] (the "New Pledgor"), pursuant to Section
3.5 of the Security Agreement. The New Pledgor hereby agrees to be bound as a
Guarantor and as a Pledgor party to the Security Agreement by all of the terms,
covenants and conditions set forth in the Security Agreement to the same extent
that it would have been bound if it had been a signatory to the Security
Agreement on the date of the Security Agreement. The New Pledgor also hereby
agrees to be bound as a party by all of the terms, covenants and conditions
applicable to it set forth in Articles VI and VII of the Credit Agreement to the
same extent that it would have been bound if it had been a signatory to the
Credit Agreement on the execution date of the Credit Agreement. Without limiting
the generality of the foregoing, the New Pledgor hereby grants and pledges to
the Collateral Agent, as collateral security for the full, prompt and complete
payment and performance



                                      -2-

when due (whether at stated maturity, by acceleration or otherwise) of the
Secured Obligations, a Lien on and security interest in, all of its right, title
and interest in, to and under the Pledged Collateral and expressly assumes all
obligations and liabilities of a Guarantor and Pledgor thereunder. The New
Pledgor hereby makes each of the representations and warranties and agrees to
each of the covenants applicable to the Pledgors contained in the Security
Agreement and Articles VI and VII of the Credit Agreement.

            Annexed hereto are supplements to each of the schedules to the
Security Agreement and the Credit Agreement, as applicable, with respect to the
New Pledgor. Such supplements shall be deemed to be part of the Security
Agreement or the Credit Agreement, as applicable.

            This Joinder Agreement and any amendments, waivers, consents or
supplements hereto may be executed in any number of counterparts and by
different parties hereto in separate counterparts, each of which when so
executed and delivered shall be deemed to be an original, but all such
counterparts together shall constitute one and the same agreement.

            THIS JOINDER AGREEMENT SHALL BE GOVERNED BY, AND SHALL BE CONSTRUED
AND ENFORCED IN ACCORDANCE WITH, THE LAW OF THE STATE OF NEW YORK.



                                      -3-

            IN WITNESS WHEREOF, the New Pledgor has caused this Joinder
Agreement to be executed and delivered by its duly authorized officer as of the
date first above written.

                CONTROL AGREEMENT CONCERNING SECURITIES ACCOUNTS

            This Control Agreement Concerning Securities Accounts (this "Control
Agreement"), dated as of [       ], by and among [       ] (the "Pledgor"),
Bank of America, N.A., as Collateral Agent (the "Collateral Agent") and [      ]
(the "Securities Intermediary"), is delivered pursuant to Section 3.4(c) of that
certain security agreement (as amended, amended and restated, supplemented or
otherwise modified from time to time, the "Security Agreement"), dated as of
February 10, 2005 made by AMR HOLDCO, INC., a Delaware corporation ("AMR
Holdco"), and EMCARE HOLDCO, INC., a Delaware corporation ("EmCare Holdco")
(each of AMR Holdco and EmCare Holdco, a "Borrower" and, together, the
"Borrowers") and THE GUARANTORS party thereto and the Collateral Agent. This
Control Agreement is for the purpose of perfecting the security interests of the
Secured Parties granted by the Pledgor in the Designated Accounts described
below. All references herein to the "UCC" shall mean the Uniform Commercial Code
as in effect from time to time in the State of New York. Capitalized terms used
but not defined herein shall have the meanings assigned to such terms in the
Security Agreement.

            Section 1. Confirmation of Establishment and Maintenance of
Designated Accounts. The Securities Intermediary hereby confirms and agrees that
(i) the Securities Intermediary has established for the Pledgor and maintains
the account(s) listed in Schedule I annexed hereto (such account(s), together
with each such other securities account maintained by the Pledgor with the
Securities Intermediary collectively, the "Designated Accounts" and each a
"Designated Account"), (ii) each Designated Account will be maintained in the
manner set forth herein until termination of this Control Agreement, (iii) this
Control Agreement is the valid and legally binding obligation of the Securities
Intermediary, (iv) the Securities Intermediary is a "securities intermediary" as
defined in Article 8-102(a)(14) of the UCC, (v) each of the Designated Accounts
is a "securities account" as such term is defined in Section 8-501(a) of the UCC
and (vi) all securities or other property underlying any financial assets which
are credited to any Designated Account shall be registered in the name of the
Securities Intermediary, endorsed to the Securities Intermediary or in blank or
credited to another securities account maintained in the name of the Securities
Intermediary and in no case will any financial asset credited to any Designated
Account be registered in the name of the Pledgor, payable to the order of the
Pledgor or specially endorsed to the Pledgor, except to the extent the foregoing
have been specially endorsed to the Securities Intermediary or in blank.

            Section 2. "Financial Assets" Election. All parties hereto agree
that each item of Investment Property and all other property held in or credited
to any Designated Account



                                      -2-

(the "Account Property") shall be treated as a "financial asset" within the
meaning of Section 8-102(a)(9) of the UCC.

            Section 3. Entitlement Order. If at any time the Securities
Intermediary shall receive an "entitlement order" (within the meaning of Section
8-102(a)(8) of the UCC) issued by the Collateral Agent and relating to any
financial asset maintained in one or more of the Designated Accounts, the
Securities Intermediary shall comply with such entitlement order without further
consent by the Pledgor or any other person. The Securities Intermediary shall
also comply with instructions directing the Securities Intermediary with respect
to the sale, exchange or transfer of financial assets held in each Designated
Account originated by a Pledgor, or any representative of, or investment manager
appointed by, a Pledgor until such time as the Collateral Agent delivers a
Notice of Sole Control pursuant to Section 9(i) to the Securities Intermediary.
The Securities Intermediary shall comply with, and is fully entitled to rely
upon, any entitlement order from the Collateral Agent, even if such entitlement
order is contrary to any entitlement order that the Pledgor may give or may have
given to the Securities Intermediary.

            Section 4. Subordination of Lien; Waiver of Set-Off. The Securities
Intermediary hereby agrees that any security interest in, lien on, encumbrance,
claim or (except as provided in the next sentence) right of setoff against, any
Designated Account or any Account Property it now has or subsequently obtains
shall be subordinate to the security interest of the Collateral Agent in the
Designated Accounts and the Account Property therein or credited thereto. The
Securities Intermediary agrees not to exercise any present or future right of
recoupment or set-off against any of the Designated Accounts or to assert
against any of the Designated Accounts any present or future security interest,
banker's lien or any other lien or claim (including claim for penalties) that
the Securities Intermediary may at any time have against or in any of the
Designated Accounts or any Account Property therein or credited thereto;
provided, however, that the Securities Intermediary may set off all amounts due
to the Securities Intermediary in respect of its customary fees and expenses for
the routine maintenance and operation of the Designated Accounts, including
overdraft fees and amounts advanced to settle authorized transactions.

            Section 5. Choice of Law. Both this Control Agreement and the
Designated Accounts shall be governed by the laws of the State of New York.
Regardless of any provision in any other agreement, for purposes of the UCC, New
York shall be deemed to be the Securities Intermediary's jurisdiction and the
Designated Accounts (as well as the security entitlements related thereto) shall
be governed by the laws of the State of New York.

            Section 6. Conflict with Other Agreements; Amendments. As of the
date hereof, there are no other agreements entered into between the Securities
Intermediary and the Pledgor with respect to any Designated Account or any
security entitlements or other financial assets credited thereto (other than
standard and customary documentation with respect to the establishment and
maintenance of such Designated Accounts). The Securities Intermediary and the
Pledgor will not enter into any other agreement with respect to any Designated
Account unless the Collateral Agent shall have received prior written notice
thereof. The Securities



                                      -3-

Intermediary and the Pledgor have not and will not enter into any other
agreement with respect to (i) creation or perfection of any security interest in
or (ii) control of security entitlements maintained in any of the Designated
Accounts or purporting to limit or condition the obligation of the Securities
Intermediary to comply with entitlement orders with respect to any Account
Property held in or credited to any Designated Account as set forth in Section 3
hereof without the prior written consent of the Collateral Agent acting in its
reasonable discretion. In the event of any conflict with respect to control over
any Designated Account between this Control Agreement (or any portion hereof)
and any other agreement now existing or hereafter entered into, the terms of
this Control Agreement shall prevail. No amendment or modification of this
Control Agreement or waiver of any rights hereunder shall be binding on any
party hereto unless it is in writing and is signed by all the parties hereto.

            Section 7. Certain Agreements.

            (i) As of the date hereof, the Securities Intermediary has furnished
to the Collateral Agent the most recent account statement issued by the
Securities Intermediary with respect to each of the Designated Accounts and the
financial assets and cash balances held therein, identifying the financial
assets held therein in a manner reasonably acceptable to the Collateral Agent.
Each such statement accurately reflects the assets held in such Designated
Account as of the date thereof.

            (ii) The Securities Intermediary will, upon its receipt of each
supplement to the Security Agreement signed by the Pledgor and identifying one
or more financial assets as "Pledged Collateral," enter into its records,
including computer records, with respect to each Designated Account a notation
with respect to any such financial asset so that such records and reports
generated with respect thereto identify such financial asset as "Pledged."

            Section 8. Notice of Adverse Claims. Except for the claims and
interest of the Collateral Agent and of the Pledgor in the Account Property held
in or credited to the Designated Accounts, the Securities Intermediary on the
date hereof does not know of any claim to, security interest in, lien on, or
encumbrance against, any Designated Account or Account Property held in or
credited thereto and does not know of any claim that any person or entity other
than the Collateral Agent has been given "control" (within the meaning of
Section 8-106 of the UCC) of any Designated Account or any such Account
Property. If the Securities Intermediary becomes aware that any person or entity
is asserting any lien, encumbrance, security interest or adverse claim
(including any writ, garnishment, judgment, warrant of attachment, execution or
similar process or any claim of control) against any of the Account Property
held in or credited to any Designated Account, the Securities Intermediary shall
promptly notify the Collateral Agent and the Pledgor thereof.

            Section 9. Maintenance of Designated Accounts. In addition to the
obligations of the Securities Intermediary in Section 3 hereof, the Securities
Intermediary agrees to maintain the Designated Accounts as follows:



                                      -4-

            (i) Notice of Sole Control. If at any time the Collateral Agent
      delivers to the Securities Intermediary a notice instructing the
      Securities Intermediary to terminate Pledgor's access to any Designated
      Account (the "Notice of Sole Control"), the Securities Intermediary agrees
      that, after receipt of such notice, it will take all instructions with
      respect to such Designated Account solely from the Collateral Agent,
      terminate all instructions and orders originated by the Pledgor with
      respect to the Designated Accounts or any Account Property therein, and
      cease taking instructions from Pledgor, including, without limitation,
      instructions for investment, distribution or transfer of any financial
      asset maintained in any Designated Account. Permitting settlement of
      trades pending at the time of receipt of such notice shall not constitute
      a violation of the immediately preceding sentence.

            (ii) Voting Rights. Until such time as the Securities Intermediary
      receives a Notice of Sole Control, the Pledgor, or an investment manager
      on behalf of the Pledgor, shall direct the Securities Intermediary with
      respect to the voting of any financial assets credited to any Designated
      Account.

            (iii) Statements and Confirmations. The Securities Intermediary will
      send copies of all statements and other correspondence (excluding routine
      confirmations) concerning any Designated Account or any financial assets
      credited thereto simultaneously to each of the Pledgor and the Collateral
      Agent at the address set forth in Section 11 hereof. The Securities
      Intermediary will provide to the Collateral Agent, upon the Collateral
      Agent's request therefor from time to time and, in any event, as of the
      last business day of each calendar month, a statement of the market value
      of each financial asset maintained in each Designated Account. The
      Securities Intermediary shall not change the name or account number of any
      Designated Account without the prior written consent of the Collateral
      Agent.

            (iv) Perfection in Certificated Securities. The Securities
      Intermediary acknowledges that, in the event that it should come into
      possession of any certificate representing any security or other Account
      Property held in or credited to any of the Designated Accounts, the
      Securities Intermediary shall retain possession of the same on behalf and
      for the benefit of the Collateral Agent and such act shall cause the
      Securities Intermediary to be deemed holding such certificate for the
      Collateral Agent, if necessary to perfect the Collateral Agent's security
      interest in such securities or assets. The Securities Intermediary hereby
      acknowledges its receipt of a copy of the Security Agreement, which shall
      also serve as notice to the Securities Intermediary of a security interest
      in collateral held on behalf and for the benefit of the Collateral Agent.

            Section 10. Successors; Assignment. The terms of this Control
Agreement shall be binding upon, and shall inure to the benefit of, the parties
hereto and their respective corporate successors and permitted assignees.

of the Securities Intermediary hereunder and this Control Agreement shall

the Collateral Agent has notified the Securities Intermediary of such
termination in writing.

            (ii) The Securities Intermediary, acting alone, may terminate this

necessary to facilitate the transfer of any Account Property in or credited to
the Designated Accounts as follows: (i) in the case of a termination of this
Control Agreement under Section 12(i), to the institution designated in writing

                              Designated Account(s)



                                                                       EXHIBIT 5

                                    [Form of]

                  CONTROL AGREEMENT CONCERNING DEPOSIT ACCOUNTS

            This CONTROL AGREEMENT CONCERNING DEPOSIT ACCOUNTS (this "Control
Agreement"), dated as of [    ], by and among [    ] (the "Pledgor"), BANK OF
AMERICA, N.A. (the "Collateral Agent") and [    ] (the "Bank"), is delivered
pursuant to Section 3.4(b) of that certain security agreement (as amended,
amended and restated, supplemented or otherwise modified from time to time, the
"Security Agreement"), dated as of February 10, 2005 made by AMR HOLDCO, INC., a
Delaware corporation ("AMR Holdco"), and EMCARE HOLDCO, INC., a Delaware
corporation ("EmCare Holdco") (each of AMR Holdco and EmCare Holdco, a
"Borrower" and, together, the "Borrowers") and THE GUARANTORS party thereto and
the Collateral Agent. This Control Agreement is for the purpose of perfecting
the security interests of the Secured Parties granted by the Pledgor in the
Designated Accounts described below. All references herein to the "UCC" shall
mean the Uniform Commercial Code as in effect from time to time in the State of
New York. Capitalized terms used but not defined herein shall have the meanings
assigned to such terms in the Security Agreement.

            Section 1. Confirmation of Establishment and Maintenance of
Designated Accounts. The Bank hereby confirms and agrees that (i) the Bank has
established for the Pledgor and maintains the deposit account(s) listed in
Schedule 1 annexed hereto (such account(s), together with each such other
deposit account maintained by the Pledgor with the Bank collectively, the
"Designated Accounts" and each a "Designated Account"), (ii) each Designated
Account will be maintained in the manner set forth herein until termination of
this Control Agreement, (iii) the Bank is a "bank," as such term is defined in
the UCC, (iv) this Control Agreement is the valid and legally binding obligation
of the Bank and (v) each Designated Account is a "deposit account" as such term
is defined in Article 9 of the UCC.

            Section 2. Control. The Bank shall comply with instructions
originated by the Collateral Agent without further consent of the Pledgor or any
person acting or purporting to act for the Pledgor being required, including,
without limitation, directing disposition of the funds in each Designated
Account. The Bank shall also comply with instructions directing the disposition
of funds in each Designated Account originated by the Pledgor or its authorized
representatives until such time as the Collateral Agent delivers a Notice of
Sole Control pursuant to Section 8(i) hereof to the Bank. The Bank shall comply
with, and is fully entitled to rely upon, any instruction from the Collateral
Agent, even if such instruction is contrary to any instruction that the Pledgor
may give or may have given to the Bank.



                                      -2-

            Section 3. Subordination of Lien; Waiver of Set-Off. The Bank hereby
agrees that any security interest in, lien on, encumbrance, claim or (except as
provided in the next sentence) right of setoff against, any Designated Account
or any funds therein it now has or subsequently obtains shall be subordinate to
the security interest of the Collateral Agent in the Designated Accounts and the
funds therein or credited thereto. The Bank agrees not to exercise any present
or future right of recoupment or set-off against any of the Designated Accounts
or to assert against any of the Designated Accounts any present or future
security interest, banker's lien or any other lien or claim (including claim for
penalties) that the Bank may at any time have against or in any of the
Designated Accounts or any funds therein; provided, however, that the Bank may
set off (i) all amounts due to the Bank in respect of its customary fees and
expenses for the routine maintenance and operation of the Designated Accounts,
including overdraft fees, and (ii) the face amount of any checks or other items
which have been credited to any Designated Account but are subsequently returned
unpaid because of uncollected or insufficient funds).

            Section 4. Choice of Law. Both this Control Agreement and the
Designated Accounts shall be governed by the laws of the State of New York.
Regardless of any provision in any other agreement, for purposes of the UCC, New
York shall be deemed to be the Bank's jurisdiction and the Designated Account(s)
shall be governed by the law of the State of New York.

            Section 5. Conflict with Other Agreements; Amendments. As of the
date hereof, there are no other agreements entered into between the Bank and the
Pledgor with respect to any Designated Account or any funds credited thereto
(other than standard and customary documentation with respect to the
establishment and maintenance of such Designated Accounts). The Bank and the
Pledgor will not enter into any other agreement with respect to any Designated
Account unless the Collateral Agent shall have received prior written notice
thereof. The Bank and the Pledgor have not and will not enter into any other
agreement with respect to control of the Designated Accounts or purporting to
limit or condition the obligation of the Bank to comply with any orders or
instructions with respect to any Designated Account as set forth in Section 2
hereof without the prior written consent of the Collateral Agent acting in its
sole discretion. In the event of any conflict with respect to control over any
Designated Account between this Control Agreement (or any portion hereof) and
any other agreement now existing or hereafter entered into, the terms of this
Control Agreement shall prevail. No amendment or modification of this Control
Agreement or waiver of any right hereunder shall be binding on any party hereto
unless it is in writing and is signed by all the parties hereto.



                                       -3-

            Section 6. Certain Agreements. As of the date hereof, the Bank has
furnished to the Collateral Agent the most recent account statement issued by
the Bank with respect to each of the Designated Accounts and the cash balances
held therein. Each such statement accurately reflects the assets held in such
Designated Account as of the date thereof.

            Section 7. Notice of Adverse Claims. Except for the claims and
interest of the Secured Parties and of the Pledgor in the Designated Accounts,
the Bank on the date hereof does not know of any claim to, security interest in,
lien on, or encumbrance against, any Designated Account or in any funds credited
thereto and does not know of any claim that any person or entity other than the
Collateral Agent has been given control (within the meaning of Section 9-104 of
the UCC) of any Designated Account or any such funds. If the Bank becomes aware
that any person or entity is asserting any lien, encumbrance, security interest
or adverse claim (including any writ, garnishment, judgment, warrant of
attachment, execution or similar process or any claim of control) against any
funds in any Designated Account, the Bank shall promptly notify the Collateral
Agent and the Pledgor thereof.

            Section 8. Maintenance of Designated Accounts. In addition to the
obligations of the Bank in Section 2 hereof, the Bank agrees to maintain the
Designated Accounts as follows:

            (i) Notice of Sole Control. If at any time the Collateral Agent
      delivers to the Bank a notice instructing the Bank to terminate Pledgor's
      access to any Designated Account (the "Notice of Sole Control"), the Bank
      agrees that, after receipt of such notice, it will take all instruction
      with respect to such Designated Account solely from the Collateral Agent,
      terminate all instructions and orders originated by the Pledgor with
      respect to the Designated Accounts or any funds therein, and cease taking
      instructions from the Pledgor, including, without limitation, instructions
      for distribution or transfer of any funds in any Designated Account.

            (ii) Statements and Confirmations. The Bank will send copies of all
      statements and other correspondence (excluding routine confirmations)
      concerning any Designated Account simultaneously to the Pledgor and the
      Collateral Agent at the address set forth in Section 10 hereof. The Bank
      will promptly provide to the Collateral Agent, upon request therefor from
      time to time and, in any event, as of the last business day of each
      calendar month, a statement of the cash balance in each Designated
      Account. The Bank shall not change the name or account number of any
      Designated Account without the prior written consent of the Collateral
      Agent.

            Section 9. Successors; Assignment. The terms of this Control
Agreement shall be binding upon, and shall inure to the benefit of, the parties
hereto and their respective corporate successors and permitted assignees.



                                      -4-

            Section 10. Notices. Any notice, request or other communication

termination date.

            (iii) Prior to any termination of this Control Agreement pursuant to
