constituting Collateral (subclauses (A), (B), (C), (D), (E), (F), G), (H) and

actions, filings and recordations described above, including the Perfection

which writing shall incorporate the provisions hereof and shall be in form and
substance satisfactory to the Collateral Agent, (G) upon the acquisition after
the date hereof by any Grantor of any motor vehicle or other Equipment subject
to a certificate of title or ownership (other than a Motor Vehicle or Equipment
that is subject to a purchase money security interest), causing the Collateral
Agent to be listed as the lienholder on such certificate of title or ownership
and delivering evidence of the same to the Collateral Agent in accordance with
Section 5(j) hereof; and (H) taking all actions required by any earlier versions

         (b) LOCATION OF EQUIPMENT AND INVENTORY. Each Grantor will keep the
Equipment and Inventory (i) at the locations specified therefor on Schedule III

Schedule III delivered by the Grantors to Collateral Agent from time to time)
and with respect to which the Collateral Agent has filed financing statements

acquisition of Equipment or Inventory, such Grantor shall deliver to the
Collateral Agent a new Schedule III indicating such new locations.

         (c) CONDITION OF EQUIPMENT AND OWNERSHIP OF COLLATERAL. (i) Each
Grantor will maintain or cause the Equipment (necessary or useful to its
business) to be maintained and preserved in good condition, repair and working

reasonable time after the occurrence thereof, make or cause to be made all
repairs, replacements and other improvements in connection therewith which are
necessary or desirable, consistent with past practice, or which the Collateral
Agent may reasonably request to such end. Any Grantor will promptly furnish to
the Collateral Agent a statement describing in reasonable detail any such loss
or damage in excess of $100,000 per occurrence to any Equipment.

              (ii) Each Grantor will be at all time the sole and exclusive owner

against, the Equipment and Inventory, except to the extent the validity thereof
is being contested in good faith by proper proceedings which stay the imposition
of any penalty, fine or Lien resulting from the non-payment thereof and with
respect to which adequate reserves in accordance with GAAP have been set aside
for the payment thereof.

         (e) INSURANCE.

              (i) Each Grantor will, at its own expense, maintain insurance
(including, without limitation, commercial general liability and property
insurance) with respect to its assets in such amounts, against such risks, in
such form and with responsible and reputable insurance companies or associations
as is required by any Governmental Authority having jurisdiction with respect
thereto or as is carried generally in accordance with sound business practice by
companies in similar businesses similarly situated and in any event, in amount,
adequacy and scope reasonably satisfactory to the Collateral Agent. To the
extent requested by the Collateral Agent at any time and from time to time, each
such policy for liability insurance shall provide for all losses to be paid on
behalf of the Collateral Agent and any Grantor as their respective interests may
appear, and each policy for property damage insurance shall provide for all
losses to be adjusted with, and paid directly to, the Collateral Agent. To the
extent requested by the Collateral Agent at any time and from time to time, each
such policy shall in addition (A) name the Collateral Agent as an additional
insured party thereunder (without any representation or warranty by or
obligation upon the Collateral Agent) as their interests may appear, (B) contain
an agreement by the insurer that any loss thereunder shall be payable to the
Collateral Agent on its own account notwithstanding any action, inaction or
breach of representation or warranty by any Grantor, (C) provide that there
shall be no recourse against the Collateral Agent for payment of premiums or
other amounts with respect thereto, and (D) provide that at least 30 days' prior
written notice of cancellation, lapse, expiration or other adverse change shall
be given to the Collateral Agent by the insurer. Any Grantor will, if so
requested by the Collateral Agent, deliver to the Collateral Agent original or
duplicate policies of such insurance and, as often as the Collateral Agent may
reasonably request, a report of a reputable insurance broker with respect to
such insurance. Any Grantor will also, at the request of the Collateral Agent,
execute and deliver instruments of assignment of such insurance policies and
cause the respective insurers to acknowledge notice of such assignment.

              (ii) Reimbursement under any liability insurance maintained by any
Grantor pursuant to this Section 5(e) may be paid directly to the Person who
shall have incurred liability covered by such insurance. Following an Event of
Default, in the case of any loss involving damage to Equipment or Inventory, any
proceeds of insurance maintained by any Grantor pursuant to this Section 5(e)
shall be paid to the Collateral Agent (except as to which paragraph (iii) of
this Section 5(e) is not applicable), any Grantor will make or cause to be made
the necessary repairs to or replacements of such Equipment or Inventory, and any
proceeds of insurance maintained by any Grantor pursuant to this Section 5(e)
shall promptly be paid by the Collateral Agent to any Grantor as reimbursement
for the costs of such repairs or replacements.

              (iii) Following and during the continuance of an Event of Default,
all insurance payments in respect of such Equipment, Inventory or any other
assets shall be paid to the Collateral Agent and applied as specified in SECTION
7(b) hereof.

         (f) PROVISIONS CONCERNING THE ACCOUNTS AND THE LICENSES.

              (i) Each Grantor will (A) give the Collateral Agent at least 30
days' prior written notice of any change in such Grantor's name, identity or
organizational structure, (B) maintain its jurisdiction of incorporation,
organization or formation as set forth in Schedule I hereto, (C) immediately
notify the Collateral Agent upon obtaining an organizational identification
number, if on the date hereof such Grantor did not have such identification
number, and (D) keep adequate records concerning the Accounts and Chattel Paper.

<PAGE>

              (ii) Each Grantor will, except as otherwise provided in this
subsection (f), continue to collect, at its own expense, all amounts due or to
become due under the Accounts. In connection with such collections, any Grantor
may (and, at the Collateral Agent's direction, will) take such action as any
Grantor or the Collateral Agent may reasonably deem necessary or advisable to
enforce collection or performance of the Accounts; provided, however, that the
Collateral Agent shall have the right at any time, upon the occurrence and
during the continuance of an Event of Default, to notify the account debtors or
obligors under any Accounts of the assignment of such Accounts to the Collateral
Agent and to direct such account debtors or obligors to make payment of all
amounts due or to become due to any Grantor thereunder directly to the
Collateral Agent or its designated agent and, upon such notification and at the
expense of any Grantor and to the extent permitted by law, to enforce collection
of any such Accounts and to adjust, settle or compromise the amount or payment
thereof, in the same manner and to the same extent as any Grantor might have
done. After receipt by any Grantor of a notice from the Collateral Agent that
the Collateral Agent has notified, intends to notify, or has enforced or intends
to enforce any Grantor's rights against the account debtors or obligors under
any Accounts as referred to in the proviso to the immediately preceding
sentence, (A) all amounts and proceeds (including Instruments) received by any
Grantor in respect of the Accounts shall be received in trust for the benefit of
the Collateral Agent hereunder, shall be segregated from other funds of any
Grantor and shall be forthwith paid over to the Collateral Agent in the same
form as so received (with any necessary endorsement) to be applied as specified
in Section 7(b) hereof, and (B) no Grantor will adjust, settle or compromise the
amount or payment of any Account or release wholly or partly any account debtor
or obligor thereof or allow any credit or discount thereon. In addition, upon
the occurrence and during the continuance of an Event of Default, the Collateral
Agent may (in its sole and absolute discretion) direct any or all of the banks
and financial institutions with which any Grantor either maintains a Deposit
Account or a lockbox or deposits the proceeds of any Accounts to send
immediately to the Collateral Agent by wire transfer (to such account as the
Collateral Agent shall specify, or in such other manner as the Collateral Agent
shall direct) all or a portion of such securities, cash, investments and other
items held by such institution. Any such securities, cash, investments and other
items so received by the Collateral Agent shall be applied as specified in
accordance with Section 7(b) hereof.

              (iii) Upon the occurrence and during the continuance of any breach
or default under any material License referred to in Schedule II hereto by any
party thereto other than any Grantor, each Grantor party thereto will, promptly
after obtaining knowledge thereof, give the Collateral Agent written notice of
the nature and duration thereof, specifying what action, if any, it has taken
and proposes to take with respect thereto and thereafter will take reasonable
steps to protect and preserve its rights and remedies in respect of such breach
or default, or will obtain or acquire an appropriate substitute License.

              (iv) Each Grantor will, at its expense, promptly deliver to the
Collateral Agent a copy of each notice or other communication received by it by
which any other party to any material License referred to in Schedule II hereto
purports to exercise any of its rights or affect any of its obligations
thereunder, together with a copy of any reply by such Grantor thereto.

                                     - 14 -

<PAGE>

              (v) Each Grantor will exercise promptly and diligently each and
every right which it may have under each material License (other than any right
of termination) and will duly perform and observe in all respects all of its
obligations under each material License and will take all action reasonably
necessary to maintain such Licenses in full force and effect. No Grantor will,
without the prior written consent of the Collateral Agent, cancel, terminate,
amend or otherwise modify in any respect, or waive any provision of, any
material License referred to in Schedule II hereto.

         (g) TRANSFERS AND OTHER LIENS.

              (i) Except as expressly permitted by the Purchase Agreements or
the other Transaction Documents, no Grantor will sell, assign (by operation of
law or otherwise), lease, license, exchange or otherwise transfer or dispose of
any of the Collateral, except (A) Inventory in the ordinary course of business,
and (B) worn out or obsolete assets, not necessary to the business.

              (ii) Except as expressly permitted by the Purchase Agreements or
the other Transaction Documents, no Grantor will create, suffer to exist or
grant any Lien upon or with respect to any Collateral, other than the Liens
created by this Agreement or the other Transaction Documents.

         (h) INTELLECTUAL PROPERTY.

              (i) If applicable, any Grantor shall, upon the Collateral Agent's
written request, duly execute and deliver the applicable Assignment for Security
in the form attached hereto as Exhibit A. Each Grantor (either itself or through
licensees) will, and will cause each licensee thereof to, take all action
necessary to maintain all of the Intellectual Property in full force and effect,
including, without limitation, using the proper statutory notices and markings
and using the Trademarks on each applicable trademark class of goods in order to
so maintain the Trademarks in full force and free from any claim of abandonment
for non-use, and each Grantor will not (nor knowingly permit any licensee
thereof to) do any act or knowingly omit to do any act whereby any Intellectual
Property may become invalidated; provided, however, that so long as no Event of
Default has occurred and is continuing, no Grantor shall have an obligation to
use or to maintain any Intellectual Property (A) that relates solely to any
product or work, that has been, or is in the process of being, discontinued,
abandoned or terminated, (B) that is being replaced with Intellectual Property
substantially similar to the Intellectual Property that may be abandoned or
otherwise become invalid, so long as the failure to use or maintain such
Intellectual Property does not materially adversely affect the validity of such
replacement Intellectual Property and so long as such replacement Intellectual
Property is subject to the Lien created by this Agreement or (C) that is
substantially the same as another Intellectual Property that is in full force,
so long the failure to use or maintain such Intellectual Property does not
materially adversely affect the validity of such replacement Intellectual
Property and so long as such other Intellectual Property is subject to the Lien
and security interest created by this Agreement. Each Grantor will cause to be
taken all necessary steps in any proceeding before the United States Patent and

                                     - 15 -

<PAGE>

Trademark Office and the United States Copyright Office or any similar office or
agency in any other country or political subdivision thereof to maintain each
registration of the Intellectual Property (other than the Intellectual Property
described in the proviso to the immediately preceding sentence), including,
without limitation, filing of renewals, affidavits of use, affidavits of
incontestability and opposition, interference and cancellation proceedings and
payment of maintenance fees, filing fees, taxes or other governmental fees. If
any Intellectual Property (other than Intellectual Property described in the
proviso to the second sentence of subsection (i) of this clause (h)) is
infringed, misappropriated, diluted or otherwise violated in any material
respect by a third party, each Grantor shall (x) upon learning of such
infringement, misappropriation, dilution or other violation, promptly notify the
Collateral Agent and (y) to the extent any Grantor shall deem appropriate under
the circumstances, promptly sue for infringement, misappropriation, dilution or
other violation, seek injunctive relief where appropriate and recover any and
all damages for such infringement, misappropriation, dilution or other
violation, or take such other actions as such Grantor shall deem appropriate
under the circumstances to protect such Intellectual Property. Each Grantor
shall furnish to the Collateral Agent from time to time upon its request
statements and schedules further identifying and describing the Intellectual
Property and Licenses and such other reports in connection with the Intellectual
Property and Licenses as the Collateral Agent may reasonably request, all in
reasonable detail and promptly upon request of the Collateral Agent. Following
receipt by the Collateral Agent of any such statements, schedules or reports,
each Grantor shall modify this Agreement by amending Schedule II hereto to
include any Intellectual Property and/or License, as the case may be, which
becomes part of the Collateral under this Agreement and shall execute and
authenticate such documents and do such acts as shall be necessary or, in the
reasonable judgment of the Collateral Agent, desirable to subject such
Intellectual Property and/or Licenses to the Lien and security interest created
by this Agreement. Notwithstanding anything herein to the contrary, upon the
occurrence and during the continuance of an Event of Default, no Grantor may
abandon or otherwise permit any Intellectual Property to become invalid without
the prior written consent of the Collateral Agent, and if any Intellectual
Property is infringed, misappropriated, diluted or otherwise violated in any
material respect by a third party, each Grantor will take such action as the
Collateral Agent shall deem appropriate under the circumstances to protect such
Intellectual Property.

              (ii) In no event shall any Grantor, either itself or through any
agent, employee, licensee or designee, file an application for the registration
of any Trademark or Copyright or the issuance of any Patent with the United
States Patent and Trademark Office or the United States Copyright Office, as
applicable, or in any similar office or agency of the United States or any
country or any political subdivision thereof unless it gives the Collateral
Agent prior written notice thereof. Upon request of the Collateral Agent, any
Grantor shall execute, authenticate and deliver any and all assignments,
agreements, instruments, documents and papers as the Collateral Agent may
reasonably request to evidence the Collateral Agent's security interest
hereunder in such Intellectual Property and the General Intangibles of any
Grantor relating thereto or represented thereby, and each Grantor hereby
appoints the Collateral Agent its attorney-in-fact to execute and/or
authenticate and file all such writings for the foregoing purposes, all acts of
such attorney being hereby ratified and confirmed, and such power (being coupled
with an interest) shall be irrevocable until the Satisfaction in Full of the
Obligations.

reasonably satisfactory to the Collateral Agent, duly executed by each Grantor
and such bank or financial institution, or enter into other arrangements in form
and substance satisfactory to the Collateral Agent, pursuant to which such
institution shall irrevocably agree, INTER ALIA, that (i) it will comply at any
time with the instructions originated by the Collateral Agent to such bank or
financial institution directing the disposition of cash, Commodity Contracts,
securities, Investment Property and other items from time to time credited to
such account, without further consent of each Grantor, which instructions the
Collateral Agent will not give to such bank or other financial institution in
the absence of a continuing Event of Default, (ii) all Commodity Contracts,
securities, Investment Property and other items of each Grantor deposited with
such institution shall be subject to a perfected, first priority security
interest in favor of the Collateral Agent, (iii) any right of set off (other
than recoupment of standard fees), banker's Lien or other similar Lien, security
interest or encumbrance shall be fully waived as against the Collateral Agent,
and (iv) upon receipt of written notice from the Collateral Agent during the
continuance of an Event of Default, such bank or financial institution shall
immediately send to the Collateral Agent by wire transfer (to such account as
the Collateral Agent shall specify, or in such other manner as the Collateral
Agent shall direct) all such cash, the value of any Commodity Contracts,
securities, Investment Property and other items held by it. Without the prior
written consent of the Collateral Agent, no Grantor shall make or maintain any
Deposit Account, Commodity Account or Securities Account except for the accounts
set forth in Schedule IV hereto. The provisions of this paragraph 5(i) shall not
apply to (i) Deposit Accounts for which the Collateral Agent is the depositary
and (ii) Deposit Accounts specially and exclusively used for payroll, payroll
taxes and other employee wage and benefit payments to or for the benefit of each
Grantor's salaried or hourly employees.

         (j) MOTOR VEHICLES.

              (i) Upon the Collateral Agent's written request, each Grantor
shall deliver to the Collateral Agent originals of the certificates of title or
ownership for all motor vehicles owned by such Grantor with a value in excess of
$50,000, with the Collateral Agent listed as lienholder, for the benefit of the
Buyers.

              (ii) Each Grantor hereby appoints the Collateral Agent as its
attorney-in-fact, effective the date hereof and terminating upon the termination
of this Agreement, for the purpose of (A) executing on behalf of such Grantor
title or ownership applications for filing with appropriate state agencies to
enable motor vehicles now owned or hereafter acquired by such Grantor to be
retitled and the Collateral Agent listed as lienholder thereof, (B) filing such
applications with such state agencies, and (C) executing such other documents
and instruments on behalf of, and taking such other action in the name of, such
Grantor as the Collateral Agent may reasonably deem necessary or advisable to
accomplish the purposes hereof (including, without limitation, for the purpose
of creating in favor of the Collateral Agent a perfected Lien on the motor
vehicles and exercising the rights and remedies of the Collateral Agent
hereunder). This appointment as attorney-in-fact is coupled with an interest and
is irrevocable until the Satisfaction in Full of the Obligations.

the terms hereof shall be accompanied by odometer statements for each motor
vehicle covered thereby.

              (iv) So long as no Event of Default shall have occurred and be
continuing, upon the request of any Grantor, the Collateral Agent shall execute
and deliver to any Grantor such instruments as any Grantor shall reasonably
request to remove the notation of the Collateral Agent as lienholder on any
certificate of title for any motor vehicle; PROVIDED, HOWEVER, that any such
instruments shall be delivered, and the release effective, only upon receipt by
the Collateral Agent of a certificate from any Grantor stating that such motor
vehicle is to be sold or has suffered a casualty loss (with title thereto in
such case passing to the casualty insurance company therefor in settlement of
the claim for such loss) and the amount that any Grantor will receive as sale
proceeds or insurance proceeds.

         (k) CONTROL. Each Grantor hereby agrees to take any or all action that

number issued to such Grantor) and (iii) ratifies such authorization to the
extent that the Collateral Agent has filed any such financing or continuation
statements, or amendments thereto, prior to the date hereof. A photocopy or
other reproduction of this Agreement or any financing statement covering the
Collateral or any part thereof shall be sufficient as a financing statement
where permitted by law.

         (b) Each Grantor hereby irrevocably appoints the Collateral Agent as
its attorney-in-fact and proxy, with full authority in the place and stead of
such Grantor and in the name of such Grantor or otherwise, from time to time in
the Collateral Agent's discretion, so long as an Event of Default shall have
occurred and is continuing, to take any action and to execute any instrument
which the Collateral Agent may reasonably deem necessary or advisable to
accomplish the purposes of this Agreement (subject to the rights of each Grantor
under Section 5 hereof), including, without limitation, (i) to obtain and adjust
insurance required to be paid to the Collateral Agent pursuant to Section 5(e)
hereof, (ii) to ask, demand, collect, sue for, recover, compound, receive and
give acquittance and receipts for moneys due and to become due under or in
respect of any Collateral, (iii) to receive, endorse, and collect any drafts or
other instruments, documents and chattel paper in connection with clause (i) or
(ii) above, (iv) to file any claims or take any action or institute any
proceedings which the Collateral Agent may deem necessary or desirable for the
collection of any Collateral or otherwise to enforce the rights of the
Collateral Agent and the Buyers with respect to any Collateral, and (v) to
execute assignments, licenses and other documents to enforce the rights of the
Collateral Agent and the Buyers with respect to any Collateral. This power is
coupled with an interest and is irrevocable until the Satisfaction in Full of
the Obligations.

         (c) For the purpose of enabling the Collateral Agent to exercise rights
and remedies hereunder, at such time as the Collateral Agent shall be lawfully
entitled to exercise such rights and remedies, and for no other purpose, each
Grantor hereby grants to the Collateral Agent, to the extent assignable, an
irrevocable, non-exclusive license (exercisable without payment of royalty or
other compensation to any Grantor) to use, assign, license or sublicense any
Intellectual Property now owned or hereafter acquired by such Grantor, wherever
the same may be located, including in such license reasonable 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 thereof. Notwithstanding
anything contained herein to the contrary, but subject to the provisions of the

                                     - 19 -

<PAGE>

Purchase Agreements that limit the right of any Grantor to dispose of its
property, and Section 5(g) and Section 5(h) hereof, so long as no Event of
Default shall have occurred and be continuing, any Grantor may exploit, use,
enjoy, protect, license, sublicense, assign, sell, dispose of or take other
actions with respect to the Intellectual Property in the ordinary course of its
business. In furtherance of the foregoing, unless an Event of Default shall have
occurred and be continuing, the Collateral Agent shall from time to time, upon
the request of any Grantor, execute and deliver any instruments, certificates or
other documents, in the form so requested, which such Grantor shall have
certified are appropriate (in such Grantor's judgment) to allow it to take any
action permitted by this Agreement (including relinquishment of the license
provided pursuant to this clause (c) as to any Intellectual Property). Further,
upon the Satisfaction in Full of the Obligations, the Collateral Agent (subject
to Section 10(e) hereof) shall release and reassign to any Grantor all of the
Collateral Agent's right, title and interest in and to the Intellectual
Property, and the Licenses, all without recourse, representation or warranty
whatsoever. The exercise of rights and remedies hereunder by the Collateral
Agent shall not terminate the rights of the holders of any licenses or
sublicenses theretofore granted by each Grantor in accordance with the second
sentence of this clause (c). Each Grantor hereby releases the Collateral Agent
from any claims, causes of action and demands at any time arising out of or with
respect to any actions taken or omitted to be taken by the Collateral Agent
under the powers of attorney granted herein other than actions taken or omitted
to be taken through the Collateral Agent's gross negligence or willful
misconduct, as determined by a final determination of a court of competent
jurisdiction.

         (d) If any Grantor fails to perform any agreement or obligation
contained herein, the Collateral Agent may itself perform, or cause performance
of, such agreement or obligation, in the name of such Grantor or the Collateral
Agent, and the expenses of the Collateral Agent incurred in connection therewith
shall be payable by such Grantor pursuant to Section 8 hereof and shall be
secured by the Collateral.

         (e) The powers conferred on the Collateral Agent hereunder are solely
to protect its interest in the Collateral and shall not impose any duty upon it
to exercise any such powers. Except for the safe custody of any Collateral in
its possession and the accounting for moneys actually received by it hereunder,
the Collateral Agent shall have no duty as to any Collateral or as to the taking
of any necessary steps to preserve rights against prior parties or any other
rights pertaining to any Collateral.

         (f) Anything herein to the contrary notwithstanding (i) each Grantor
shall remain liable under the Licenses and otherwise with respect to any of the
Collateral to the extent set forth therein to perform all of its obligations
thereunder to the same extent as if this Agreement had not been executed, (ii)
the exercise by the Collateral Agent of any of its rights hereunder shall not
release any Grantor from any of its obligations under the Licenses or otherwise
in respect of the Collateral, and (iii) the Collateral Agent shall not have any
obligation or liability by reason of this Agreement under the Licenses or with
respect to any of the other Collateral, nor shall the Collateral Agent be
obligated to perform any of the obligations or duties of any Grantor thereunder
or to take any action to collect or enforce any claim for payment assigned
hereunder.

         SECTION 7. REMEDIES UPON EVENT OF DEFAULT. If any Event of Default
shall have occurred and be continuing:

         (a) The Collateral Agent may exercise in respect of the Collateral, in
addition to any other rights and remedies provided for herein or otherwise
available to it, all of the rights and remedies of a secured party upon default
under the Code (whether or not the Code applies to the affected Collateral), and
also may (i) take absolute control of the Collateral, including, without
limitation, transfer into the Collateral Agent's name or into the name of its
nominee or nominees (to the extent the Collateral Agent has not theretofore done
so) and thereafter receive, for the benefit of the Collateral Agent, all
payments made thereon, give all consents, waivers and ratifications in respect
thereof and otherwise act with respect thereto as though it were the outright
owner thereof, (ii) require each Grantor to, and each Grantor hereby agrees that
it will at its expense and upon request of the Collateral Agent forthwith,
assemble all or part of its respective Collateral as directed by the Collateral
Agent and make it available to the Collateral Agent at a place or places to be
designated by the Collateral Agent that is reasonably convenient to both
parties, and the Collateral Agent may enter into and occupy any premises owned
or leased by any Grantor where the Collateral or any part thereof is located or
assembled for a reasonable period in order to effectuate the Collateral Agent's
rights and remedies hereunder or under law, without obligation to any Grantor in
respect of such occupation, and (iii) without notice except as specified below
and without any obligation to prepare or process the Collateral for sale, (A)
sell the Collateral or any part thereof in one or more parcels at public or
private sale, at any of the Collateral Agent's offices or elsewhere, for cash,
on credit or for future delivery, and at such price or prices and upon such
other terms as the Collateral Agent may deem commercially reasonable and/or (B)
lease, license or dispose of the Collateral or any part thereof upon such terms
as the Collateral Agent may deem commercially reasonable. Each Grantor agrees
that, to the extent notice of sale or any other disposition of its respective
Collateral shall be required by law, at least ten (10) days' prior notice to any
Grantor of the time and place of any public sale or the time of any private sale
or other disposition of its respective Collateral is to be made shall constitute
reasonable notification. The Collateral Agent shall not be obligated to make any
sale or other disposition of any Collateral regardless of notice of sale having
been given. The Collateral Agent may adjourn any public or private sale from
time to time by announcement at the time and place fixed therefor, and such sale
may, without further notice, be made at the time and place to which it was so
adjourned. Each Grantor hereby waives any claims against the Collateral Agent
and the Buyers arising by reason of the fact that the price at which its
respective Collateral may have been sold at a private sale was less than the
price which might have been obtained at a public sale or was less than the
aggregate amount of the Obligations, even if the Collateral Agent accepts the
first offer received and does not offer such Collateral to more than one
offeree, and waives all rights that any Grantor may have to require that all or
any part of such Collateral be marshaled upon any sale (public or private)
thereof. Each Grantor hereby acknowledges that (i) any such sale of its
respective Collateral by the Collateral Agent shall be made without warranty,
(ii) the Collateral Agent may specifically disclaim any warranties of title,
possession, quiet enjoyment or the like, and (iii) such actions set forth in
clauses (i) and (ii) above shall not adversely affect the commercial
reasonableness of any such sale of Collateral. In addition to the foregoing, (1)
upon written notice to any Grantor from the Collateral Agent after and during
the continuance of an Event of Default, such Grantor shall cease any use of the
Intellectual Property or any trademark, patent or copyright similar thereto for
any purpose described in such notice; (2) the Collateral Agent may, at any time
and from time to time after and during the continuance of an Event of Default,

                                     - 21 -

<PAGE>

upon 10 days' prior notice to such Grantor, license, whether general, special or
otherwise, and whether on an exclusive or non-exclusive basis, any of the
Intellectual Property, throughout the universe for such term or terms, on such
conditions, and in such manner, as the Collateral Agent shall in its sole
discretion determine; and (3) the Collateral Agent may, at any time, pursuant to
the authority granted in Section 6 hereof (such authority being effective upon
the occurrence and during the continuance of an Event of Default), execute and
deliver on behalf of such Grantor, one or more instruments of assignment of the
Intellectual Property (or any application or registration thereof), in form
suitable for filing, recording or registration in any country.

         (b) Any cash held by the Collateral Agent as Collateral and all Cash
Proceeds received by the Collateral Agent in respect of any sale of or
collection from, or other realization upon, all or any part of the Collateral
shall be applied (after payment of any amounts payable to the Collateral Agent
pursuant to SECTION 8 hereof) by the Collateral Agent against, all or any part
of the Obligations in such order as the Collateral Agent shall elect, consistent
with the provisions of the Transaction Documents. Any surplus of such cash or
Cash Proceeds held by the Collateral Agent and remaining after the Satisfaction
in Full of the Obligations shall be paid over to whomsoever shall be lawfully
entitled to receive the same or as a court of competent jurisdiction shall
direct.

         (c) In the event that the proceeds of any such sale, collection or
realization are insufficient to pay all amounts to which the Collateral Agent
and the Buyers are legally entitled, each Grantor shall be liable for the
deficiency, together with interest thereon at the highest rate specified in the
Notes for interest on overdue principal thereof or such other rate as shall be
fixed by applicable law, together with the costs of collection and the
reasonable fees, costs, expenses and other client charges of any attorneys
employed by the Collateral Agent to collect such deficiency.

         (d) Each Grantor hereby acknowledges that if the Collateral Agent
complies with any applicable state, provincial, or federal law requirements in
connection with a disposition of the Collateral, such compliance will not
adversely affect the commercial reasonableness of any sale or other disposition
of the Collateral.

         (e) The Collateral Agent shall not be required to marshal any present
or future collateral security (including, but not limited to, this Agreement and
the Collateral) for, or other assurances of payment of, the Obligations or any
of them or to resort to such collateral security or other assurances of payment
in any particular order, and all of the Collateral Agent's rights hereunder and
in respect of such collateral security and other assurances of payment shall be
cumulative and in addition to all other rights, however existing or arising. To
the extent that any Grantor lawfully may, each Grantor hereby agrees that it
will not invoke any law relating to the marshaling of collateral which might
cause delay in or impede the enforcement of the Collateral Agent's rights under
this Agreement or under any other instrument creating or evidencing any of the
Obligations or under which any of the Obligations is outstanding or by which any
of the Obligations is secured or payment thereof is otherwise assured, and, to
the extent that it lawfully may, each Grantor hereby irrevocably waives the
benefits of all such laws.

         SECTION 8. INDEMNITY AND EXPENSES.

         (a) Each Grantor agrees, jointly and severally, to defend, protect,
indemnify and hold the Collateral Agent and each of the Buyers, jointly and
severally, harmless from and against any and all claims, damages, losses,
liabilities, obligations, penalties, fees, costs and expenses (including,
without limitation, reasonable legal fees, costs, expenses, and disbursements of
such Person's counsel) to the extent that they arise out of or otherwise result
from this Agreement (including, without limitation, enforcement of this
Agreement), except to the extent resulting from such Person's gross negligence
or willful misconduct, as determined by a final judgment of a court of competent
jurisdiction.

         (b) Each Grantor agrees, jointly and severally, to pay to the
Collateral Agent upon demand the amount of any and all costs and expenses,
including the reasonable fees, costs, expenses and disbursements of counsel for
the Collateral Agent and of any experts and agents (including, without
limitation, any collateral trustee which may act as agent of the Collateral
Agent), which the Collateral Agent may incur in connection with (i) the
preparation, negotiation, execution, delivery, recordation, administration,
amendment, waiver or other modification or termination of this Agreement, (ii)
the custody, preservation, use or operation of, or the sale of, collection from,
or other realization upon, any Collateral, (iii) the exercise or enforcement of
any of the rights of the Collateral Agent hereunder, or (iv) the failure by any
Grantor to perform or observe any of the provisions hereof.

         SECTION 9. NOTICES, ETC. All notices and other communications provided
for hereunder shall be in writing and shall be mailed (by certified mail,
postage prepaid and return receipt requested), telecopied, or delivered, if to
any Grantor to the address of the Company set forth in each Purchase Agreement,
or if to the Collateral Agent or any Buyer, to it at its respective address set
forth in the Purchase Agreements; or as to any such Person, at such other
address as shall be designated by such Person in a written notice to such other
Person complying as to delivery with the terms of this Section 9. All such
notices and other communications shall be effective (i) if mailed (by certified
mail, postage prepaid and return receipt requested), when received or three
Business Days after deposited in the mails, whichever occurs first; (ii) if
telecopied, when transmitted and confirmation is received, provided same is on a
Business Day and, if not, on the next Business Day; or (iii) if delivered by
hand, upon delivery, provided same is on a Business Day and, if not, on the next
Business Day. For the avoidance of doubt, the Subsidiaries, as Grantors, hereby
appoint the Company as its agent for receipt of service of process and all
notices and other communications in the United States at the address specified
in the Purchase Agreements.

         SECTION 10. MISCELLANEOUS.

         (a) No amendment of any provision of this Agreement shall be effective
unless it is in writing and signed by each Grantor and the Collateral Agent, and
no waiver of any provision of this Agreement, and no consent to any departure by
each Grantor therefrom, shall be effective unless it is in writing and signed by
each Grantor and the Collateral Agent, and then such waiver or consent shall be
effective only in the specific instance and for the specific purpose for which
given.

                                     - 23 -

<PAGE>

         (b) No failure on the part of the Collateral Agent to exercise, and no
delay in exercising, any right hereunder or under any of the other Transaction
Documents shall operate as a waiver thereof; nor shall any single or partial
exercise of any such right preclude any other or further exercise thereof or the
exercise of any other right. The rights and remedies of the Collateral Agent or
any Buyer provided herein and in the other Transaction Documents are cumulative
and are in addition to, and not exclusive of, any rights or remedies provided by
law. The rights of the Collateral Agent or any Buyer under any of the other
Transaction Documents against any party thereto are not conditional or
contingent on any attempt by such Person to exercise any of its rights under any
of the other Transaction Documents against such party or against any other
Person, including but not limited to, any Grantor.

         (c) Any provision of this Agreement that is prohibited or unenforceable
in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent
of such prohibition or unenforceability without invalidating the remaining
portions hereof or thereof or affecting the validity or enforceability of such
provision in any other jurisdiction.

         (d) This Agreement shall create a continuing security interest in the
Collateral and shall (i) remain in full force and effect until the Satisfaction
in Full of the Obligations, and (ii) be binding on each Grantor and all other
Persons who become bound as debtor to this Agreement in accordance with Section
9-203(d) of the Code and shall inure, together with all rights and remedies of
the Collateral Agent and the Buyers hereunder, to the benefit of the Collateral
Agent and the Buyers and their respective permitted successors, transferees and
assigns. Without limiting the generality of clause (ii) of the immediately
preceding sentence, without notice to any Grantor, the Collateral Agent and the
Buyers may assign or otherwise transfer their rights and obligations under this
Agreement and any of the other Transaction Documents in accordance with the
respective Transaction Documents, to any other Person and such other Person
shall thereupon become vested with all of the benefits in respect thereof
granted to the Collateral Agent and the Buyers herein or otherwise. Upon any
such assignment or transfer, all references in this Agreement to the Collateral
Agent or any such Buyer shall mean the assignee of the Collateral Agent or such
Buyer. None of the rights or obligations of any Grantor hereunder may be
assigned or otherwise transferred without the prior written consent of the
Collateral Agent, and any such assignment or transfer without the consent of the
Collateral Agent shall be null and void.

         (e) Upon the Satisfaction in Full of the Obligations, (i) this
Agreement, the powers of attorney granted hereunder, and the security interests
created hereby shall terminate and all rights to the Collateral shall revert to
the respective Grantor that granted such security interests hereunder, and (ii)
the Collateral Agent will, upon any Grantor's request and at such Grantor's
expense, (A) return to such Grantor such of the Collateral as shall not have
been sold or otherwise disposed of or applied pursuant to the terms hereof, and
(B) execute and deliver to such Grantor such documents as such Grantor shall
reasonably request to evidence such termination, all without any representation,
warranty or recourse whatsoever.

         (f) THIS AGREEMENT SHALL BE GOVERNED BY, CONSTRUED AND INTERPRETED IN
ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK, EXCEPT AS REQUIRED BY
MANDATORY PROVISIONS OF LAW AND EXCEPT TO THE EXTENT THAT THE VALIDITY AND
PERFECTION OR THE PERFECTION AND THE EFFECT OF PERFECTION OR NON-PERFECTION OF
THE SECURITY INTEREST CREATED HEREBY, OR REMEDIES HEREUNDER, IN RESPECT OF ANY
PARTICULAR COLLATERAL ARE GOVERNED BY THE LAW OF A JURISDICTION OTHER THAN THE
STATE OF NEW YORK.

         (g) ANY LEGAL ACTION, SUIT OR PROCEEDING WITH RESPECT TO THIS AGREEMENT
OR ANY DOCUMENT RELATED HERETO MAY BE BROUGHT IN THE COURTS OF THE STATE OF NEW
YORK IN THE COUNTY OF NEW YORK OR THE UNITED STATES OF AMERICA FOR THE SOUTHERN
DISTRICT OF NEW YORK, AND APPELLATE COURTS THEREOF, AND, BY EXECUTION AND
DELIVERY OF THIS AGREEMENT, EACH GRANTOR HEREBY ACCEPTS FOR ITSELF AND IN
RESPECT OF ITS PROPERTY, GENERALLY AND UNCONDITIONALLY, THE JURISDICTION OF THE
AFORESAID COURTS. EACH GRANTOR HEREBY EXPRESSLY AND IRREVOCABLY WAIVES, TO THE
FULLEST EXTENT PERMITTED BY LAW, ANY OBJECTION, INCLUDING, WITHOUT LIMITATION,
ANY OBJECTION TO THE LAYING OF VENUE OR BASED ON THE GROUNDS OF FORUM NON
CONVENIENS, WHICH IT MAY NOW OR HEREAFTER HAVE TO THE BRINGING OF ANY SUCH
ACTION, SUIT OR PROCEEDING IN SUCH RESPECTIVE JURISDICTIONS AND CONSENTS TO THE
GRANTING OF SUCH LEGAL OR EQUITABLE RELIEF AS IS DEEMED APPROPRIATE BY THE
COURT.

         (h) EACH GRANTOR AND (BY ITS ACCEPTANCE OF THE BENEFITS OF THIS
AGREEMENT) THE COLLATERAL AGENT WAIVES ANY RIGHT IT MAY HAVE TO TRIAL BY JURY IN
RESPECT OF ANY LITIGATION BASED ON, ARISING OUT OF, UNDER OR IN CONNECTION WITH
THIS AGREEMENT OR ANY OF THE OTHER TRANSACTION DOCUMENTS, OR ANY COURSE OF
CONDUCT, COURSE OF DEALING, ORAL OR WRITTEN STATEMENT OR OTHER ACTION OF THE
PARTIES HERETO.

         (i) Each Grantor and the Collateral Agent irrevocably consent to the
service of process of any of the aforesaid courts in any such action, suit or
proceeding by the mailing of copies thereof by registered or certified mail (or
any substantially similar form of mail), postage prepaid, at its address
provided herein, such service to become effective when received or 10 days after
such mailing, whichever first occurs.

         (j) Nothing contained herein shall affect the right of any party to
serve process in any other manner permitted by law or commence legal proceedings

have to claim or recover in any legal action, suit or proceeding referred to in
this Section 10 any special, exemplary, punitive or consequential damages.

         (l) Section headings herein are included for convenience of reference
only and shall not constitute a part of this Agreement for any other purpose.

         (m) This Agreement may be executed in any number of counterparts and by
different parties hereto in separate counterparts, each of which shall be deemed
to be an original, but all of which taken together constitute one in the same
Agreement.

         (n) This Agreement constitutes an amendment and restatement of the
Original Security Agreement. The execution and delivery of this Agreement and
the consummation of the transactions contemplated hereby are not intended by the
parties to be, and shall not constitute, a novation or an accord and
satisfaction of the Obligations or any other obligations owing to Collateral
Agent or the Buyers under the Original Security Agreement or any other Original
Secured Transaction Document. Each of the parties hereto hereby acknowledges and
agrees that the grant of the security interests in the Collateral pursuant to
this Agreement and in any other Transaction Document is not intended to, nor
shall it be construed, as constituting a release of any prior security interests
granted by any Grantor in favor of Collateral Agent for the benefit of itself
and the Buyers in or to any Collateral or any other property of such Grantor,
but is intended to constitute a restatement and reconfirmation of the prior
security interests granted by the Grantors (as applicable) in favor of
Collateral Agent for the benefit of itself and the Buyers in and to the
Collateral and a grant of a new security interest in (i) any Collateral that was
not included in the grant of security interests by the Grantors party to the
Original Security Agreement and (ii) any Collateral of any Grantor party hereto
that was not a party to the Original Security Agreement, in each case, in favor
of Collateral Agent for the benefit of itself and the Buyers.

distributions, cash, instruments, investment property and any other property
(including, but not limited to, any stock dividend and any distribution in
connection with a stock split) from time to time received, receivable or
otherwise distributed in respect of or in exchange for any or all of the
foregoing and all cash and noncash proceeds thereof (collectively, the "PLEDGED

         (b) all present and future increases, profits, combinations,

in each case, whether now owned or hereafter acquired by such Pledgor and
howsoever its interest therein may arise or appear (whether by ownership,
security interest, Lien, claim or otherwise).

Notwithstanding anything herein to the contrary, the term "Collateral" shall not
include in the case of a Subsidiary of such Pledgor organized under the laws of
a jurisdiction other than the United States, any of the states thereof or the
District of Columbia (a "FOREIGN SUBSIDIARY"), more than 65% (or such greater

parent and (ii) would not reasonably be expected to cause any material adverse
tax consequences) of the issued and outstanding shares of Capital Stock entitled
to vote (within the meaning of Treas. Reg. Section 1.956-2(c)(2)) (it being
understood and agreed that the Collateral shall include 100% of the issued and
outstanding shares of Capital Stock not entitled to vote (within the meaning of
Treas. Reg. Section 1.956-2(c)(2)) or other equity interest of such Foreign
Subsidiary). "Capital Stock" means (i) with respect to any Person that is a
corporation, any and all shares, interests, participations or other equivalents

respect to any Person that is not a corporation, any and all partnership,

functions of or pertaining to government. "Lien" means any mortgage, lien,

The Pledgors agree that the pledge of the shares of Capital Stock acquired by a

Subsidiary may be supplemented by one or more separate pledge agreements, deeds
of pledge, share charges, or other similar agreements or instruments, executed
and delivered by the relevant Pledgors in favor of the Collateral Agent, which
pledge agreements will provide for the pledge of such shares of Capital Stock in
accordance with the laws of the applicable foreign jurisdiction. With respect to
such shares of Capital Stock, the Collateral Agent may, at any time and from
time to time, in its sole discretion, take actions in such foreign jurisdictions
that will result in the perfection of the Lien created in such shares of Capital
Stock.

         SECTION 3. Security for Obligations. The security interest created
hereby in the Collateral constitutes continuing collateral security for all of
the following obligations, whether now existing or hereafter incurred (the
"OBLIGATIONS"):

defined below), the payment by the Company, as and when due and payable (by
scheduled maturity, required prepayment, acceleration, demand or otherwise in
accordance with the terms of the Notes), of all amounts from time to time owing
by it in respect of the Purchase Agreements, the Notes and the other Transaction
Documents, and (ii) the payment by each of the Guarantors (as defined in the
Guaranty), as and when due and payable of all "Guaranteed Obligations" under
(and as defined in) the Guaranty, including, without limitation, (A) all
principal of and interest on the Notes (including, without limitation, all
interest that accrues after the commencement of any bankruptcy proceeding of the
Pledgors, whether or not the payment of such interest is unenforceable or is not
allowable due to the existence of such bankruptcy proceeding), and (B) all fees,
commissions, expense reimbursements, indemnifications and all other amounts due
or to become due under any of the Transaction Documents; and

              (b) until the Satisfaction in Full of the Obligations, the due
performance and observance by each Pledgor of all of its other obligations from
time to time existing in respect of any of the Transaction Documents.

         As used herein, "Satisfaction in Full of the Obligations" means the
satisfaction in full of all indebtedness and other obligations owed by the
Company to the Buyers under the Notes and the other Transaction Documents
(including, without limitation, all principal, interest (including, without
limitation, all interest that accrues after the commencement of any Insolvency
Proceeding of any Pledgor, whether or not the payment of such interest is
unenforceable or is not allowable due to the existence of such Insolvency
Proceeding), and fees, but excluding obligations under the Transaction Documents

         SECTION 4. Delivery of the Collateral.

              (a) All certificates currently representing the Pledged Shares
shall be delivered to the Collateral Agent on or prior to the execution and
delivery of this Agreement. All other promissory notes, certificates and
instruments constituting Collateral from time to time or required to be pledged
to the Collateral Agent pursuant to the terms of this Agreement (the "ADDITIONAL
COLLATERAL") shall be delivered to the Collateral Agent promptly upon receipt
thereof by or on behalf of any of the Pledgors. All such promissory notes,
certificates and instruments shall be held by the Collateral Agent pursuant
hereto and shall be delivered in suitable form for transfer by delivery or shall
be accompanied by duly executed instruments of transfer or assignment or undated
stock powers executed in blank, all in form and substance reasonably
satisfactory to the Collateral Agent. If any Collateral consists of
uncertificated securities, unless the immediately following sentence is
applicable thereto, the Pledgors shall cause the Collateral Agent (or its
designated custodian, nominee or other designee) to become the registered holder
thereof, or cause each issuer of such securities to agree that it will comply
with instructions originated by the Collateral Agent (or its designated
custodian, nominee or other designee) with respect to such securities without
further consent by the Pledgors. If any Collateral consists of securities
entitlements, the Pledgors shall transfer such securities entitlements to the
Collateral Agent (or its designated custodian, nominee or other designee) or
cause the applicable securities intermediary to agree that it will comply with
entitlement orders by the Collateral Agent (or its designated custodian, nominee
or other designee) without further consent by the Pledgors.

              (b) Promptly upon the receipt by any Pledgor of any Additional
Collateral, a Pledge Amendment, duly executed by such Pledgor, in substantially
the form of Annex I hereto (a "PLEDGE AMENDMENT"), shall be delivered to the
Collateral Agent, in respect of the Additional Collateral which is or are to be
pledged pursuant to this Agreement, which Pledge Amendment shall from and after
delivery thereof constitute part of Schedule I hereto. Each Pledgor hereby
authorizes the Collateral Agent to attach each Pledge Amendment to this
Agreement and agrees that all promissory notes, certificates or instruments
listed on any Pledge Amendment shall for all purposes hereunder constitute
Collateral and such Pledgor shall be deemed upon delivery thereof to have made
the representations and warranties set forth in Section 5 with respect to such
Additional Collateral as of the date of the Pledge Amendment.

              (c) If any Pledgor shall receive, by virtue of such Pledgor's
being or having been an owner of any Collateral, any (i) stock certificate
(including, without limitation, any certificate representing a stock dividend or
distribution in connection with any increase or reduction of capital,
reclassification, merger, consolidation, sale of assets, combination of shares,
stock split, spin-off or split-off), promissory note or other instrument, (ii)
option or right, whether as an addition to, substitution for, or in exchange
for, any Collateral, or otherwise, (iii) dividends payable in cash (except such
dividends permitted to be retained by such Pledgor pursuant to Section 7 hereof)
or in securities or other property or (iv) dividends, distributions, cash,
instruments, investment property and other property in connection with a partial

                                     - 6 -

<PAGE>

or total liquidation or dissolution or in connection with a reduction of
capital, capital surplus or paid-in surplus, such Pledgor shall receive such
stock certificate, promissory note, instrument, option, right, payment or
distribution in trust for the benefit of the Collateral Agent, shall segregate
it from such Pledgor's other property and shall deliver it forthwith to the
Collateral Agent in the exact form received, with any necessary endorsement
and/or appropriate stock powers duly executed in blank, to be held by the
Collateral Agent as Collateral and as further collateral security for the
Obligations.

         SECTION 5. Representations and Warranties. Each Pledgor jointly and
severally represents and warrants as of the date of this Agreement as follows:

              (a) Each Pledgor (i) is a corporation, limited liability company
or limited partnership duly organized, validly existing and in good standing
under the laws of the state or jurisdiction of its organization, and (ii) has
all corporate, limited liability company or limited partnership power and
authority to execute, deliver and perform this Agreement.

              (b) The execution, delivery and performance by each Pledgor of
this Agreement (i) have been duly authorized by all necessary corporate, limited
liability company or limited partnership action, (ii) do not and will not
contravene its charter or bylaws, its limited liability company or operating
agreement or its certificate of partnership or partnership agreement, as
applicable, or any applicable law or any contractual restriction binding on or
affecting it or any of its properties, and (iii) do not and will not result in
or require the creation of any Lien upon or with respect to any of its
properties other than pursuant to this Agreement.

              (c) The issuers of the Pledged Shares set forth in Schedule I
hereto are the Pledgors' only Subsidiaries existing on the date hereof. The
Pledged Shares have been duly authorized and validly issued, are fully paid and
nonassessable and the holders thereof are not entitled to any preemptive first
refusal or other similar rights. Except as noted in Schedule I hereto, the
Pledged Shares constitute 100% of the issued shares of capital stock,
partnership interests or membership or other equity interests, as applicable, of
the Subsidiaries. All other shares of stock constituting Collateral will be,
when issued, duly authorized and validly issued, fully paid and nonassessable.

              (d) The Pledgors are and will be at all times the legal and
beneficial owners of the Collateral free and clear of any Lien, other than Liens
created by this Agreement or the other Transaction Documents.

              (e) The exercise by the Collateral Agent of any of its rights and
remedies hereunder will not contravene any law or any contractual restriction
binding on or affecting any Pledgor or any of the properties of any Pledgor and
will not result in or require the creation of any Lien upon or with respect to
any of the properties of any Pledgor other than pursuant to this Agreement and
the other Transaction Documents.

              (f) No authorization or approval or other action by, and no notice
to or filing with, any Governmental Authority is required to be obtained by any
Pledgor for (i) the due execution, delivery and performance by any Pledgor of
this Agreement, (ii) the grant by any Pledgor, or the perfection of the security
interest and Lien purported to be created hereby in the Collateral or (iii) the
exercise by the Collateral Agent of any of its rights and remedies hereunder,
except as may be required in connection with any sale of any Collateral by laws
affecting the offering and sale of securities generally.

                                     - 7 -

<PAGE>

              (g) This Agreement creates a valid security interest and Lien in
favor of the Collateral Agent in the Collateral, as security for the
Obligations. The Collateral Agent's having possession of the promissory notes
evidencing the Collateral, the certificates representing the Pledged Shares and
all other certificates, instruments and cash constituting Collateral from time
to time results in the perfection of the security interest in such Collateral.
Such security interest and Lien is, or in the case of Collateral in which any of
the Pledgors obtains rights after the date hereof, will be, a perfected first
priority Lien. All action necessary to perfect and protect such security
interest and Lien has been duly taken, except for the Collateral Agent's having
possession of certificates, instruments, securities entitlements and cash
constituting Collateral after the date hereof.

         SECTION 6. Covenants as to the Collateral. Until Satisfaction in Full
of the Obligations, each Pledgor will, unless the Collateral Agent shall
otherwise consent in writing:

              (a) keep adequate records concerning the Collateral owned or
purported to be owned by it and permit the Collateral Agent, or any designees or
representatives thereof, at time and from time to time during reasonable hours
after prior written notice to examine and make copies of and abstracts from such
records in accordance with Section 5(l) of the Security Agreement;

              (b) at the Pledgors' joint and several expense, promptly deliver
to the Collateral Agent a copy of each material notice or other material
communication received by any Pledgor in respect of the Collateral;

              (c) at the Pledgors' joint and several expense, defend the
Collateral Agent's right, title and security interest in and to the Collateral
against the claims of any Person;

              (d) at the Pledgors' joint and several expense, at any time and
from time to time, promptly execute and deliver all further instruments and
documents and take all further action that may be necessary or that the
Collateral Agent may reasonably request in order to (i) perfect and protect, or
maintain the perfection of, the security interest and Lien purported to be
created hereby, (ii) enable the Collateral Agent to exercise and enforce its
rights and remedies hereunder in respect of the Collateral or (iii) otherwise
effect the purposes of this Agreement, including, without limitation, delivering
to the Collateral Agent irrevocable proxies in respect of the Collateral for
exercise pursuant to Section 7 hereof;

              (e) except as expressly permitted by this Agreement or the other
Transaction Documents, not sell, assign (by operation of law or otherwise),
exchange or otherwise dispose of any Collateral or any interest therein except
in the ordinary course of business;

              (f) except as expressly permitted by this Agreement or the other
Transaction Documents, not create or suffer to exist any Lien, upon or with
respect to any Collateral;

                                     - 8 -

<PAGE>

              (g) except as expressly permitted by this Agreement or the other
Transaction Documents, not make or consent to any amendment or other
modification or waiver with respect to any Collateral or enter into any
agreement or permit to exist any restriction with respect to any Collateral;

              (h) except as expressly permitted by this Agreement or the other
Transaction Documents, not permit the issuance of (i) any additional shares of
any class of capital stock, partnership interests, member interests or other
equity of any Subsidiary, (ii) any securities convertible voluntarily by the
holder thereof or automatically upon the occurrence or non-occurrence of any
event or condition into, or exchangeable for, any such shares of capital stock
of any Subsidiary or (iii) any warrants, options, contracts or other commitments
entitling any Person to purchase or otherwise acquire any such shares of capital
stock of any Subsidiary;

              (i) except as expressly permitted by this Agreement or the other
Transaction Documents, not issue any stock certificate, certificated security or
other instrument to evidence or represent any shares of capital stock, any
partnership interest or membership interest of any Subsidiary described in
Schedule I hereto; and

              (j) except as expressly permitted by this Agreement or the other
Transaction Documents, not take or fail to take any action which would in any
manner impair the validity or enforceability of the Collateral Agent's security
interest in and Lien on any Collateral.

         SECTION 7. Voting Rights, Dividends, Etc. in Respect of the Collateral.

              (a) So long as no Event of Default (as defined in the Notes) (an
"EVENT OF DEFAULT") shall have occurred and be continuing:

                   (i) each Pledgor may exercise any and all voting and other
consensual rights pertaining to any Collateral for any purpose not inconsistent
with the terms of this Agreement, the Purchase Agreements or the other
Transaction Documents; provided, however, that (A) no Pledgor will exercise or
refrain from exercising any such right, as the case may be, if the Collateral
Agent gives it notice that, in the Collateral Agent's judgment, such action (or
inaction) is reasonably likely to have a Material Adverse Effect and (B) each
Pledgor will give the Collateral Agent at least five (5) Business Days' notice
of the manner in which it intends to exercise, or the reasons for refraining
from exercising, any such right which is reasonably likely to have a Material
Adverse Effect;

                   (ii) the Pledgors may receive and retain any and all
dividends, interest or other distributions paid in respect of the Collateral to
the extent permitted by the Purchase Agreements; provided, however, that any and
all (A) dividends and interest paid or payable other than in cash in respect of,
and instruments and other property received, receivable or otherwise distributed
in respect of or in exchange for, any Collateral, (B) dividends and other
distributions paid or payable in cash in respect of any Collateral in connection
with a partial or total liquidation or dissolution or in connection with a
reduction of capital, capital surplus or paid-in surplus, and (C) cash paid,
payable or otherwise distributed in redemption of, or in exchange for, any
Collateral, together with any dividend, distribution, interest or other payment
which at the time of such dividend, distribution, interest or other payment was
not permitted by the Purchase Agreements, shall be, and shall forthwith be

                                     - 9 -

<PAGE>

delivered to the Collateral Agent to hold as, Collateral and shall, if received
by any of the Pledgors, be received in trust for the benefit of the Collateral
Agent, shall be segregated from the other property or funds of the Pledgors, and
shall be forthwith delivered to the Collateral Agent in the exact form received
with any necessary indorsement and/or appropriate stock powers duly executed in
blank, to be held by the Collateral Agent as Collateral and as further
collateral security for the Obligations; and

                   (iii) the Collateral Agent will execute and deliver (or cause
to be executed and delivered) to a Pledgor all such proxies and other
instruments as such Pledgor may reasonably request for the purpose of enabling
such Pledgor to exercise the voting and other rights which it is entitled to
exercise pursuant to paragraph (i) of this Section 7(a) and to receive the
dividends, distributions, interest and other payments which it is authorized to
receive and retain pursuant to paragraph (ii) of this Section 7(a), in each
case, to the extent that the Collateral Agent has possession of such Collateral.

              (b) Upon the occurrence and during the continuance of an Event of
Default:

                   (i) all rights of each Pledgor to exercise the voting and
other consensual rights which it would otherwise be entitled to exercise
pursuant to paragraph (i) of this Section 7(a), and to receive the dividends,
distributions, interest and other payments which it would otherwise be
authorized to receive and retain pursuant to paragraph (ii) of this Section
7(a), shall 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 and to receive and hold as Collateral such
dividends, distributions, interest and other payments;

                   (ii) without limiting the generality of the foregoing, the
Collateral Agent may at its option exercise any and all rights of conversion,
exchange, subscription or any other rights, privileges or options pertaining to
any of the Collateral as if it were the absolute owner thereof, including,
without limitation, the right to exchange, in its discretion, any and all of the
Collateral upon the merger, consolidation, reorganization, recapitalization or

issuer of the Collateral of any right, privilege or option pertaining to any
Collateral, and, in connection therewith, to deposit and deliver any and all of
the Collateral with any committee, depository, transfer collateral agent,
registrar or other designated collateral agent upon such terms and conditions as
it may determine; and

                   (iii) all dividends, distributions, interest and other
payments which are received by any Pledgor contrary to the provisions of
paragraph (i) of this Section 7(b) shall be received in trust for the benefit of
the Collateral Agent, shall be segregated from other funds of such Pledgor, and
shall be forthwith paid over to the Collateral Agent as Collateral in the exact
form received with any necessary indorsement and/or appropriate stock powers
duly executed in blank, to be held by the Collateral Agent as Collateral and as
further collateral security for the Obligations.

         SECTION 8. Additional Provisions Concerning the Collateral.

              (a) Each Pledgor hereby (i) authorizes the Collateral Agent to
file one or more financing or continuation statements, and amendments thereto,
relating to the Collateral, without the signature of such Pledgor where
permitted by law, (ii) ratifies such authorization to the extent that the
Collateral Agent has filed any such financing or continuation statements, or
amendments thereto, without the signature of such Pledgor prior to the date
hereof and (iii) authorizes the Collateral Agent to execute any agreements,
instruments or other documents in such Pledgor's name and to file such
agreements, instruments or other documents to perfect, protect or enforce the
security interest and Lien of the Collateral Agent in the Collateral or as
provided under Article 8 or Article 9 of the Code in any appropriate filing
office.

              (b) Each Pledgor hereby irrevocably appoints the Collateral Agent
as its attorney-in-fact and proxy, with full authority in the place and stead
and in its name or otherwise, from time to time in the Collateral Agent's
discretion to take any action and to execute any instrument which the Collateral
Agent may reasonably deem necessary or advisable to accomplish the purposes of
this Agreement (subject to the rights of such Pledgor under Section 7(a)
hereof), including, without limitation, to receive, indorse and collect all
instruments made payable to such Pledgor representing any dividend, interest
payment or other distribution in respect of any Collateral and to give full
discharge for the same. This power is coupled with an interest and is
irrevocable until the termination of this Agreement in accordance with Section
13(e) hereof.

              (c) If any Pledgor fails to perform any agreement or obligation
contained herein, the Collateral Agent itself may perform, or cause performance
of, such agreement or obligation, and the expenses of the Collateral Agent
incurred in connection therewith shall be jointly and severally payable by the
Pledgors pursuant to Section 10 hereof and shall be secured by the Collateral.

              (d) Other than the exercise of reasonable care to assure the safe
custody of the Collateral while held hereunder, the Collateral Agent shall have
no duty or liability to preserve rights pertaining thereto and shall be relieved
of all responsibility for the Collateral upon surrendering it or tendering
surrender of it to any of the Pledgors. The Collateral Agent shall be deemed to
have exercised reasonable care in the custody and preservation of the Collateral
in its possession if the Collateral is accorded treatment substantially equal to
that which the Collateral Agent accords its own property, it being understood
that the Collateral Agent shall not have responsibility for (i) ascertaining or
taking action with respect to calls, conversions, exchanges, maturities, tenders
or other matters relating to any Collateral, whether or not the Collateral Agent
has or is deemed to have knowledge of such matters, or (ii) taking any necessary
steps to preserve rights against any parties with respect to any Collateral.

              (e) The powers conferred on the Collateral Agent hereunder are
solely to protect its interest in the Collateral and shall not impose any duty
upon it to exercise any such powers. Except for the safe custody of any
Collateral in its possession in accordance with Section 8(d) above and the
accounting for monies actually received by it hereunder, the Collateral Agent
shall have no duty as to any Collateral or as to the taking of any necessary
steps to preserve rights against prior parties or any other rights pertaining to
any Collateral.

              (f) Upon the occurrence and during the continuation of any Event
of Default, the Collateral Agent may at any time in its discretion (i) without
notice to the Pledgors, transfer or register in the name of the Collateral Agent
or any of its nominees any or all of the Collateral, subject only to the
revocable rights of the Pledgors under Section 7(a) hereof, and (ii) exchange
certificates or instruments constituting Collateral for certificates or
instruments of smaller or larger denominations.

         SECTION 9. Remedies Upon Default. If any Event of Default shall have
occurred and be continuing:

              (a) The Collateral Agent may exercise in respect of the
Collateral, in addition to other rights and remedies provided for herein or
otherwise available to it, all of the rights and remedies of a secured party on
default under the Code then in effect in the State of New York; and without
limiting the generality of the foregoing and without notice except as specified
below, sell the Collateral or any part thereof in one or more parcels at public
or private sale, at any exchange or broker's board or elsewhere, at such price
or prices and on such other terms as the Collateral Agent may deem commercially
reasonable. The Pledgors agree that, to the extent notice of sale shall be
required by law, at least ten (10) days' prior notice to any of the Pledgors of
the time and place of any public sale or the time of any private sale is to be
made shall constitute reasonable notification. The Collateral Agent shall not be
obligated to make any sale of Collateral regardless of notice of sale having
been given. The Collateral Agent may adjourn any public or private sale from
time to time by announcement at the time and place fixed therefor, and such sale
may, without further notice, be made at the time and place to which it was so
adjourned.

              (b) Each Pledgor recognizes that it may be impracticable to effect
a public sale of all or any part of the Pledged Shares or any other securities
constituting Collateral and that the Collateral Agent may, therefore, determine
to make one or more private sales of any such securities to a restricted group
of purchasers who will be obligated to agree, among other things, to acquire
such securities for its own account, for investment and not with a view to the
distribution or resale thereof. Each Pledgor acknowledges that any such private
sale may be at prices and on terms less favorable to the seller than the prices
and other terms which might have been obtained at a public sale and,
notwithstanding the foregoing, agrees that such private sales shall be deemed to
have been made in a commercially reasonable manner and that the Collateral Agent
shall have no obligation to delay sale of any such securities for the period of
time necessary to permit the issuer of such securities to register such
securities for public sale under the Securities Act of 1933, as amended (the
"SECURITIES ACT"). Each Pledgor further acknowledges and agrees that any offer
to sell such securities which has been (i) publicly advertised on a bona fide
basis in a newspaper or other publication of general circulation in the
financial community of New York, New York (to the extent that such an offer may
be so advertised without prior registration under the Securities Act) or (ii)
made privately in the manner described above to not less than fifteen (15) bona
fide offerees shall be deemed to involve a "public disposition" for the purposes
of Section 9-610 of the Code (or any successor or similar, applicable statutory
provision) as then in effect in the State of New York, notwithstanding that such
sale may not constitute a "public offering" under the Securities Act, and that
the Collateral Agent may, in such event, bid for the purchase of such
securities.

              (c) Any cash held by the Collateral Agent as Collateral and all
cash proceeds received by the Collateral Agent in respect of any sale of,
collection from, or other realization upon, all or any part of the Collateral
shall be applied (after payment of any amounts payable to the Collateral Agent
pursuant to Section 10 hereof) by the Collateral Agent against, all or any part
of the Obligations in such order as the Collateral Agent shall elect consistent
with the provisions of the Purchase Agreements.

              (d) In the event that the proceeds of any such sale, collection or
realization are insufficient to pay all amounts to which the Collateral Agent is
legally entitled, the Pledgors shall be jointly and severally liable for the
deficiency, together with interest thereon at the highest rate specified in the
Notes for interest on overdue principal thereof or such other rate as shall be
fixed by applicable law, together with the costs of collection and the
reasonable fees, costs and expenses of any attorneys employed by the Collateral
Agent to collect such deficiency.

         SECTION 10. Indemnity and Expenses.

              (a) Each of the Pledgors, jointly and severally, hereby agrees to
indemnify and hold the Collateral Agent (and all of its officers, directors,
employees, attorneys, and consultants) harmless from and against any and all
claims, damages, losses, liabilities, obligations, penalties, fees, costs and
expenses (including, without limitation, reasonable legal fees and disbursements
of counsel) to the extent that they arise out of or otherwise result from this
Agreement (including, without limitation, enforcement of this Agreement), except
such claims, losses or liabilities arising or resulting directly from such
Person's gross negligence or willful misconduct as determined by a court of
competent jurisdiction.

              (b) Each Pledgor shall be jointly and severally obligated for, and
will upon demand pay to the Collateral Agent the reasonable amount of any and
all out-of-pocket costs and expenses, including the reasonable fees and
disbursements of the Collateral Agent's counsel and of any experts which the
Collateral Agent may incur in connection with (i) the preparation, negotiation,
execution, delivery, recordation, administration, amendment, waiver or other
modification or termination of this Agreement, (ii) the custody, preservation,
use or operation of, or the sale of, collection from, or other realization upon,
any Collateral, (iii) the exercise or enforcement of any of the rights of the
Collateral Agent hereunder, or (iv) the failure by any Pledgor to perform or
observe any of the provisions hereof.

         SECTION 11. Notices, Etc. All notices and other communications provided
for hereunder shall be in writing and shall be mailed (by certified mail,
postage prepaid and return receipt requested), sent by Federal Express or other
recognized courier service (return receipt requested), telecopied or delivered,
if to any Pledgor, to it at the address specified for the Company in the
Purchase Agreements or if to the Collateral Agent, to it at the address
specified in each Purchase Agreement; or as to either such Person at such other
address as shall be designated by such Person in a written notice to such other
Person complying as to delivery with the terms of this Section 11. All such
notices and other communications shall be effective (i) if sent by certified
mail, postage prepaid, return receipt requested, when received or three (3)
Business Days after mailing, whichever first occurs, (ii) if telecopied, when
transmitted and confirmation is received, provided same is on a Business Day
and, if not, on the next Business Day or (iii) if delivered or sent by Federal
Express or other recognized courier service (return receipt requested), upon
delivery, provided same is on a Business Day and, if not, on the next Business
Day.

<PAGE>

         SECTION 12. Security Interest Absolute. All rights of the Collateral
Agent, all Liens and all obligations of each of the Pledgors hereunder shall be
absolute and unconditional irrespective of: (i) any lack of validity or
enforceability of the Purchase Agreements or any other Transaction Document,
(ii) any change in the time, manner or place of payment of, or in any other term
in respect of, all or any of the Obligations, or any other amendment or waiver
of or consent to any departure from the Purchase Agreements or any other
Transaction Document, (iii) any exchange or release of, or non-perfection of any
Lien on any Collateral, or any release or amendment or waiver of or consent to
departure from any guaranty, for all or any of the Obligations, or (iv) any
other circumstance which might otherwise constitute a defense available to, or a
discharge of, any of the Pledgors in respect of the Obligations (other than the
Satisfaction in Full of the Obligations). All authorizations and agencies
contained herein with respect to any of the Collateral are irrevocable and
powers coupled with an interest.

         SECTION 13. Miscellaneous.

              (a) No amendment of any provision of this Agreement shall be
effective unless it is in writing and signed by each Pledgor and the Collateral
Agent, and no waiver of any provision of this Agreement, and no consent to any
departure by the Pledgors therefrom, shall be effective unless it is in writing
and signed by the Collateral Agent, and then such waiver or consent shall be
effective only in the specific instance and for the specific purpose for which
given.

              (b) No failure on the part of the Collateral Agent to exercise,
and no delay in exercising, any right hereunder or under any other Transaction
Document shall operate as a waiver hereof or thereof; nor shall any single or
partial exercise of any such right preclude any other or further exercise hereof
or thereof or the exercise of any other right. The rights and remedies of the
Collateral Agent provided herein and in the other Transaction Documents are
cumulative and are in addition to, and not exclusive of, any rights or remedies
provided by law. The rights of the Collateral Agent under any Transaction
Document against any party thereto are not conditional or contingent on any
attempt by the Collateral Agent to exercise any of its rights under any other
Transaction Document against such party or against any other Person.

              (c) Any provision of this Agreement which is prohibited or
unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective
to the extent of such prohibition or unenforceability without invalidating the
remaining portions hereof or affecting the validity or enforceability of such
provision in any other jurisdiction.

              (d) This Agreement shall create a continuing security interest in
and Lien on the Collateral and shall (i) remain in full force and effect until
the termination of this Agreement in accordance with Section 13(e) hereof and
(ii) be binding on the Pledgors and their respective successors and assigns and
shall inure, together with all rights and remedies of the Collateral Agent, to
the benefit of the Collateral Agent and its successors, transferees and assigns.
Without limiting the generality of clause (ii) of the immediately preceding
sentence, the Collateral Agent may assign or otherwise transfer its rights and
obligations under this Agreement and any other Transaction Document to any other

                                     - 14 -

<PAGE>

Person pursuant to the terms of the respective Transaction Document, and such
other Person shall thereupon become vested with all of the benefits in respect
thereof granted to the Collateral Agent herein or otherwise. Upon any such
assignment or transfer, all references in this Agreement to the Collateral Agent
shall mean the assignee of the Collateral Agent. None of the rights or
obligations of any of the Pledgors hereunder may be assigned or otherwise
transferred without the prior written consent of the Collateral Agent, and any
such assignment or transfer without such consent shall be null and void.

              (e) Notwithstanding anything to the contrary in this Agreement,
(i) this Agreement (along with all powers of attorney granted hereunder) and the
security interests and Lien created hereby shall terminate and all rights to the
Collateral shall revert to the Pledgors upon the Satisfaction in Full of the
Obligations, and (ii) the Collateral Agent will, upon each Pledgor's request and
at each such Pledgor's expense, (A) return to such Pledgor such of the
Collateral (to the extent delivered to the Collateral Agent) as shall not have
been sold or otherwise disposed of or applied pursuant to the terms hereof, and
(B) execute and deliver to such Pledgor, without recourse, representation or
warranty, such documents as such Pledgor shall reasonably request to evidence
such termination.

              (f) The internal laws, and not the laws of conflicts, of New York
shall govern the enforceability and validity of this Agreement, the construction
of its terms and the interpretation of the rights and duties of the parties,
except as required by mandatory provisions of law and except to the extent that
the validity and perfection or the perfection and the effect of perfection or
non-perfection of the security interest and Lien created hereby, or remedies
hereunder, in respect of any particular Collateral are governed by the law of a
jurisdiction other than the State of New York.

              (g) Each party to this Agreement hereby irrevocably and
unconditionally submits, for itself and its property, to the exclusive
jurisdiction of the United States District Court for the Southern District of
New York sitting in Manhattan or the Commercial Division, Civil Branch of the
Supreme Court of the State of Yew York sitting in New York County in connection
with any suit, action or proceeding directly or indirectly arising out of, under
or in connection with this Agreement or the other Transaction Documents or the
transactions contemplated hereby or thereby. No party to this Agreement may move
to (i) transfer any such suit, action or proceeding brought in such New York
court or federal court to another jurisdiction, (ii) consolidate any such suit,
action or proceeding brought in such New York court or federal court with a
suit, action or proceeding in another jurisdiction or (iii) dismiss any such
suit, action or proceeding brought in such New York court or federal court for
the purpose of bringing the same in another jurisdiction. Each party to this
Agreement agrees that a final judgment in any such suit, action or proceeding
shall be conclusive and may be enforced in any other jurisdiction by suit on the
judgment or in any other manner provided by law. Each party to this Agreement
hereby irrevocably and unconditionally waives, to the fullest extent it may
legally and effectively do so, any objection which it may now or hereafter have
to the laying of venue of any suit, action or proceeding arising out of or
relating to this Agreement or the other Transaction Documents, in any New York
court sitting in the County of New York or any federal court sitting in the
Southern District of New York.

              (h) Each party irrevocably consents to the service of process of
any of the aforesaid courts in any such action, suit or proceeding by the
mailing of copies thereof by registered or certified mail (or any substantially
similar form of mail), postage prepaid, to such Pledgor at its address provided
herein, such service to become effective when received or 10 days after such
mailing, whichever first occurs.

              (i) Nothing contained herein shall affect the right of any party
Agent to serve process in any other manner permitted by law or commence legal
proceedings or otherwise proceed against any party or any property of any party
in any other jurisdiction.

              (j) Each party irrevocably and unconditionally waives any right it
may have to claim or recover in any legal action, suit or proceeding referred to
in this Section any special, exemplary, punitive or consequential damages.

              (k) EACH PARTY HERETO HEREBY WAIVES, TO THE FULLEST EXTENT
PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN RESPECT
OF ANY SUIT, ACTION OR PROCEEDING DIRECTLY OR INDIRECTLY ARISING OUT OF, UNDER
OR IN CONNECTION WITH THIS AGREEMENT OR OTHER TRANSACTION DOCUMENTS.

              (l) The headings herein are for convenience only, do not
constitute a part of this Agreement and shall not be deemed to limit or affect
any of the provisions hereof. The language used in this Agreement will be deemed
to be the language chosen by the parties to express their mutual intent, and no
rules of strict construction will be applied against any party.

              (m) This Agreement may be executed in any number of counterparts
and by different parties hereto in separate counterparts, each of which shall be
deemed to be an original, but all of which taken together shall constitute one
and the same agreement.

              (n) All of the obligations of the Pledgors hereunder are joint and
several. The Collateral Agent may, in its sole and absolute discretion, enforce
the provisions hereof against any of the Pledgors and shall not be required to
proceed against all Pledgors jointly or seek payment from the Pledgors ratably.
In addition, the Collateral Agent may, in its sole and absolute discretion,
select the Collateral of any one or more of the Pledgors for sale or application
to the Obligations, without regard to the ownership of such Collateral, and
shall not be required to make such selection ratably from the Collateral owned
by all of the Pledgors. The release or discharge of any Pledgor by the
Collateral Agent shall not release or discharge any other Pledgor from the
obligations of such Person hereunder.

              (o) This Agreement constitutes an amendment and restatement of the
Original Pledge Agreement. The execution and delivery of this Agreement and the
consummation of the transactions contemplated hereby are not intended by the
parties to be, and shall not constitute, a novation or an accord and
satisfaction of the Obligations or any other obligations owing to Collateral
Agent or the Buyers under the Original Pledge Agreement or any other Original
Secured Transaction Document. Each of the parties hereto hereby acknowledges and
agrees that the grant of the security interests in the Collateral pursuant to
this Agreement and in any other Transaction Document is not intended to, nor
shall it be construed, as constituting a release of any prior security interests
granted by any Pledgor in favor of Collateral Agent for the benefit of itself
and the Buyers in or to any Collateral or any other property of such Pledgor,
but is intended to constitute a restatement and reconfirmation of the prior
security interests granted by the Pledgors (as applicable) in favor of
Collateral Agent for the benefit of itself and the Buyers in and to the
Collateral and a grant of a new security interest in (i) any Collateral that was
not included in the grant of security interests by the Pledgors party to the
Original Pledge Agreement and (ii) any Collateral of any Pledgor party hereto
that was not a party to the Original Pledge Agreement, in each case, in favor of
Collateral Agent for the benefit of itself and the Buyers.
