            WHEREAS, the Grantors other than the Borrower are party to the
Subsidiary Guaranty pursuant to which they have guaranteed the Obligations (as
defined in the Credit Agreement); and

            WHEREAS, it is a condition precedent to the obligation of the
Lenders to make their respective extensions of credit to the Borrower under the
Credit Agreement that the Grantors shall have executed and delivered this
Agreement to the Collateral Agent;

            WHEREAS, in order to secure the Obligations under the First Lien
Credit Agreement (as defined therein), the Grantors have granted to the First

induce the Lenders to make their respective extensions of credit to the Borrower

respect to any Pledged Collateral pursuant to the recapitalization or
reclassification of the capital of any issuer of Pledged Collateral or pursuant
to the reorganization thereof shall, unless otherwise subject to a perfected
security interest in favor of the Collateral Agent, be delivered to the
Collateral Agent to be held by it hereunder as additional collateral security
for the Secured Obligations. If any sum of money or property so paid or
distributed in respect of any Pledged Collateral shall be received by such
Grantor, such Grantor shall, until such money or property is paid or delivered
to the Collateral Agent, hold such money or property in trust for the Collateral
Agent, (subject to the Intercreditor Agreement) segregated from other funds of
such Grantor, as additional security for the Secured Obligations.

            (c) Except as provided in Article V (Remedial Provisions), such
Grantor shall be entitled to exercise all voting, consent and corporate,
partnership, limited liability company and similar rights with respect to the
Pledged Collateral; provided, however, that no vote shall be cast, consent given
or right exercised or other action taken by such Grantor that would impair the
Collateral, be inconsistent with or result in any violation of any provision of
the Credit Agreement, this Agreement or any other Loan Document or, without
prior notice to the Collateral Agent, enable or permit any issuer of Pledged
Collateral to issue any Stock or other equity Securities of any nature or to
issue any other securities convertible into or granting the right to purchase or
exchange for any Stock or other equity Securities of any nature of any issuer of
Pledged Collateral.

            (d) Subject to the terms of the Intercreditor Agreement and except
as permitted pursuant to Section 4.10, such Grantor shall not grant "control"
(within the meaning of such term under Article 9-106 of the UCC) over any
Investment Property to any Person other than the Collateral Agent.

            (e) In the case of each Grantor that is an issuer of Pledged
Collateral, such Grantor agrees to be bound by the terms of this Agreement
relating to the Pledged Collateral issued by it and shall comply with such terms
insofar as such terms are applicable to it. In the case of any Grantor that is a
holder of any Stock or Stock Equivalent in any Person that is an issuer of
Pledged Collateral, such Grantor consents to (i) the exercise of the rights
granted to the Collateral Agent hereunder (including those described in Section
5.3 (Pledged Collateral)), and (ii) the pledge by each other Grantor, pursuant
to the terms hereof, of the Pledged Stock in such Person and to the transfer of
such Pledged Stock to the Collateral Agent or its nominee and to the
substitution of the Collateral Agent or its nominee as a holder of such Pledged
Stock with all the

rights, powers and duties of other holders of Pledged Stock of the same class
and, if the Grantor having pledged such Pledged Stock hereunder had any right,
power or duty at the time of such pledge or at the time of such substitution
beyond that of such other holders, with all such additional rights, powers and
duties. Subject to the terms of the Intercreditor Agreement, such Grantor agrees
to execute and deliver to the Collateral Agent such certificates, agreements and
other documents as may be necessary to evidence, formalize or otherwise give
effect to the consents given in this clause (e).

            (f) Such Grantor shall not, without the consent of the Collateral
Agent, agree to any amendment of any Constituent Document that in any way
adversely affects the perfection of the security interest of the Collateral
Agent in the Pledged Collateral pledged by such Grantor hereunder, including any
amendment electing to treat any membership interest or partnership interest that
is part of the Pledged Collateral as a "security" under Section 8-103 of the
UCC, or any election to turn any previously uncertificated Stock that is part of
the Pledged Collateral into certificated Stock.

            SECTION 4.5 ACCOUNTS. Such Grantor shall not, other than in the
ordinary course of business consistent with its past practice, (i) grant any
extension of the time of payment of any Account, (ii) compromise or settle any
Account for less than the full amount thereof, (iii) release, wholly or
partially, any Person liable for the payment of any Account, (iv) allow any
credit or discount on any Account or (v) amend, supplement or modify any Account
in any manner that could adversely affect the value thereof.

            SECTION 4.6 DELIVERY OF INSTRUMENTS AND CHATTEL PAPER. Subject to
the terms of the Intercreditor Agreement, if any amount in excess of $250,000
payable under or in connection with any Collateral owned by such Grantor shall
be or become evidenced by an Instrument or Chattel Paper, such Grantor shall
immediately deliver such Instrument or Chattel Paper to the Collateral Agent,
duly indorsed in a manner satisfactory to the Collateral Agent, or, if consented
to by the Collateral Agent, shall mark all such Instruments and Chattel Paper
with the following legend: "This writing and the obligations evidenced or
secured hereby are subject to the security interest of Citicorp North America,
Inc., as Collateral Agent".

            SECTION 4.7 INTELLECTUAL PROPERTY

            (a) Such Grantor (either itself or through licensees) shall (i)
continue to use each Trademark that is Material Intellectual Property in order
to maintain such Trademark in full force and effect with respect to each class
of goods for which such Trademark is currently used, free from any claim of
abandonment for non-use, (ii) maintain as in the past the quality of products
and services offered under such Trademark, (iii) use such Trademark with the
appropriate notice of registration and all other notices and legends required by
applicable Requirements of Law, (iv) not adopt or use any mark that is
confusingly similar or a colorable imitation of such Trademark unless the
Administrative Agent shall obtain a perfected security interest in such mark
pursuant to this Agreement and (v) not (and not permit any licensee or
sublicensee thereof to) do any act or knowingly omit to do any act whereby such
Trademark (or any goodwill associated therewith) may become destroyed,
invalidated, impaired or harmed in any way.

            (b) Such Grantor (either itself or through licensees) shall not do
any act, or knowingly omit to do any act, whereby any Patent that is Material
Intellectual Property may become forfeited, abandoned or dedicated to the
public.

            (c) Such Grantor (either itself or through licensees) (i) shall not
(and shall not permit any licensee or sublicensee thereof to) do any act or
knowingly omit to do any act whereby any portion of the Copyrights that is
Material Intellectual Property may become invalidated or otherwise impaired and
(ii) shall not (either itself or through licensees) do any act whereby any
portion of the Copyrights that is Material Intellectual Property may fall into
the public domain.

            (d) Such Grantor (either itself or through licensees) shall not do
any act, or knowingly omit to do any act, whereby any trade secret that is
Material Intellectual Property may become publicly available or otherwise
unprotectable.

            (e) Such Grantor (either itself or through licensees) shall not do
any act that knowingly uses any Material Intellectual Property to infringe,
misappropriate, or violate the intellectual property rights of any other Person
in any material respect.

            (f) Such Grantor shall notify the Collateral Agent promptly if it
knows, or has reason to know, that any application or registration relating to
any Material Intellectual Property may become forfeited, abandoned or dedicated
to the public, or of any adverse determination or development (including the
institution of, or any such determination or development in, any proceeding in
the United States Patent and Trademark Office, the United States Copyright
Office or any court or tribunal in any country) regarding such Grantor's
ownership of, right to use, interest in, or the validity of, any Material
Intellectual Property or such Grantor's right to register the same or to own and
maintain the same.

            (g) Whenever such Grantor, either by itself or through any agent,
licensee or designee, shall file an application for the registration of any
Intellectual Property with the United States Patent and Trademark Office, the
United States Copyright Office or any similar office or agency within or outside
the United States or register any Internet domain name, such Grantor shall
report such filing to the Collateral Agent within five Business Days after the
last day of the fiscal quarter in which such filing occurs. Upon request of the
Collateral Agent, such Grantor shall execute and deliver, and have recorded, all
agreements, instruments, documents and papers as the Collateral Agent may
request to evidence the Collateral Agent's security interest in any Copyright,
Patent, Trademark or Internet domain name and the goodwill and general
intangibles of such Grantor relating thereto or represented thereby.

            (h) Such Grantor shall take all reasonable actions necessary or
requested by the Collateral Agent, including in any proceeding before the United
States Patent and Trademark Office, the United States Copyright Office or any
similar office or agency and any Internet domain name registrar, to maintain and
pursue each application (and to obtain the relevant registration) and to
maintain each registration of any Copyright, Trademark, Patent or Internet
domain name that is Material Intellectual Property, including filing of
applications for renewal, affidavits of use, affidavits of incontestability and
opposition and interference and cancellation proceedings.

            (i) In the event that any Material Intellectual Property is or has
been infringed upon or misappropriated or diluted by a third party, to the
extent that any Grantor's interest therein has been materially impaired, such
Grantor shall notify the Collateral Agent promptly after such Grantor learns
thereof. Such Grantor shall take such action (or, if applicable, no action) as
it reasonably determines to be appropriate in the circumstances in response to
such infringement, misappropriation of dilution, which may include promptly
bringing suit for

infringement, misappropriation or dilution and to recover all damages for such
infringement, misappropriation of dilution, and shall take such other actions
may be reasonably appropriate in its reasonable judgment under the circumstances
to protect such Material Intellectual Property.

            (j) Unless otherwise agreed to by the Collateral Agent, such Grantor
shall execute and deliver to the Collateral Agent for filing in (i) the United
States Copyright Office a short-form copyright security agreement in the form

Secretary of State of all appropriate States of the United States a short-form
patent security agreement in the form attached hereto as Annex 4 (Form of Short
Form Intellectual Property Security Agreement), (iii) the United States Patent
and Trademark Office a short-form trademark security agreement in form attached
hereto as Annex 4 (Form of Short Form Intellectual Property Security Agreement)
and (iv) with the appropriate Internet domain name registrar, a duly executed
form of assignment of such Internet domain name to the Collateral Agent
(together with appropriate supporting documentation as may be requested by the
Collateral Agent) in form and substance reasonably acceptable to the Collateral
Agent. Subject to the terms of the Intercreditor Agreement, in the case of
clause (iv) above, such Grantor hereby authorizes the Collateral Agent to file
such assignment in such Grantor's name and to otherwise perform in the name of
such Grantor all other necessary actions to complete such assignment, and each
Grantor agrees to perform all appropriate actions deemed necessary by the
Collateral Agent for the Collateral Agent to ensure such Internet domain name is
registered in the name of the Collateral Agent.

            SECTION 4.8 PAYMENT OF OBLIGATIONS. Such Grantor shall pay and
discharge or otherwise satisfy at or before maturity or before they become
delinquent, as the case may be, all material taxes, assessments and governmental
charges or levies imposed upon the Collateral or in respect of income or profits
therefrom, as well as all material claims of any kind (including claims for
labor, materials and supplies) against or with respect to the Collateral, except
that no such charge need be paid if the amount or validity thereof is currently
being contested in good faith by appropriate proceedings, reserves in conformity
with GAAP with respect thereto have been provided on the books of such Grantor
and such proceedings could not reasonably be expected to result in the sale,
forfeiture or loss of any material portion of the Collateral or any interest
therein.

            SECTION 4.9 NOTICE OF COMMERCIAL TORT CLAIMS. Such Grantor agrees
that, if it shall acquire any interest in any Commercial Tort Claim reasonably
expected to result, individually, in a settlement in excess of $500,000 (whether
from another Person or because such Commercial Tort Claim shall have come into
existence), (i) such Grantor shall, immediately upon such acquisition, deliver
to the Collateral Agent, in each case in form and substance satisfactory to the
Collateral Agent, a notice of the existence and nature of such Commercial Tort
Claim and deliver a supplement to Schedule 7 (Commercial Tort Claims) containing
a specific description of such Commercial Tort Claim, (ii) the provision of
Section 2.1 (Collateral) shall apply to such Commercial Tort Claim and (iii)
such Grantor shall execute and deliver to the Collateral Agent, in each case in
form and substance satisfactory to the Collateral Agent, any certificate,
agreement and other document, and take all other action, deemed by the
Collateral Agent to be reasonably necessary or appropriate for the Collateral
Agent to obtain, on behalf of the Lenders, a second-priority, perfected security
interest in all such Commercial Tort Claims. Any supplement to Schedule 7
(Commercial Tort Claims) delivered pursuant to this Section 4.9 (Notice of
Commercial Tort Claims) shall, after the receipt thereof by the Collateral
Agent, become part of

Schedule 7 (Commercial Tort Claims) for all purposes hereunder other than in
respect of representations and warranties made prior to the date of such
receipt.

            SECTION 4.10 DEPOSIT ACCOUNTS; CONTROL ACCOUNTS.

            (a) Such Grantor shall, and shall cause each of its Subsidiaries to,
(i) deposit in an Approved Deposit Account all cash they receive, (ii) not
establish or maintain any Securities Account that is not a Control Account and
(iii) not establish or maintain any Deposit Account other than with a Deposit
Account Bank; provided, however, that the Borrower and its Subsidiaries may (i)
maintain payroll, withholding tax and other fiduciary accounts and (ii) maintain
other accounts as long as the average daily balance in each such account does
not exceed $2,000,000 and the aggregate average daily balance of all such
accounts does not exceed $10,000,000.

            (b) In the event (i) the Borrower, any Subsidiary of the Borrower or
any Deposit Account Bank shall, after the date hereof, terminate an agreement
with respect to the maintenance of an Approved Deposit Account for any reason,
(ii) the Administrative Agent shall reasonably demand such termination as a
result of the failure of a Deposit Account Bank to comply with the terms of the
applicable Deposit Account Control Agreement or (iii) the Administrative Agent
determines in its reasonable discretion that the financial condition of a
Deposit Account Bank has materially deteriorated, to the extent that the
Collateral Agent's interest in any Approved Deposit Account has been materially
impaired, such Deposit Account shall cease to be an Approved Deposit Account and
Borrower shall, and shall cause each Subsidiary of the Borrower to, to the
extent required in clause (a) above, take all necessary steps to ensure that all
future payments are made to another Approved Deposit Account.

            (c) In the event (i) the Borrower, any Subsidiary of the Borrower or
any Approved Securities Intermediary shall, after the date hereof, terminate an
agreement with respect to the maintenance of a Control Account for any reason,
(ii) the Administrative Agent shall demand such termination as a result of the
failure of an Approved Securities Intermediary to comply with the terms of the
applicable Securities Account Control Agreement or (iii) the Administrative
Agent determines in its reasonable discretion that the financial condition of a
Approved Securities Intermediary has materially deteriorated, to the extent that
the Collateral Agent's interest in any Control Account has been materially
impaired, such Control Account shall cease to be a Control Account and Borrower
shall, and shall cause each Subsidiary of the Borrower to, to the extent
required in clause (a) above, take all necessary steps to ensure that all future
payments are made to another Control Account.

            (d) The Collateral Agent (at the direction of the Administrative
Agent) may establish one or more Cash Collateral Accounts with such depositaries
and Securities Intermediaries as it in its sole discretion shall determine;
provided, however, that no Cash Collateral Account shall be established with
respect to the assets of any Excluded Foreign Subsidiary. The Borrower agrees
that each such Cash Collateral Account shall meet the requirements set forth in
the definition of "Cash Collateral Account". Without limiting the foregoing,
funds on deposit in any Cash Collateral Account may be invested (but the
Collateral Agent shall be under no obligation to make any such investment) in
Cash Equivalents at the direction of the Administrative Agent and, except during
the continuance of an Event of Default, the Collateral Agent agrees with the
Borrower to issue Entitlement Orders for such investments in Cash Equivalents as
requested by the Borrower; provided, however, that the Collateral Agent shall
not have any responsibility for, or bear any risk of loss of, any such
investment or income

thereon. None of the Borrower, any Subsidiary of the Borrower or any other Loan
Party or Person claiming on behalf of or through the Borrower, any Subsidiary of
the Borrower or any other Loan Party shall have any right to demand payment of
any funds held in any Cash Collateral Account at any time prior to the payment
in full of all then outstanding and payable monetary Obligations.

            SECTION 4.11 FOREIGN SUBSIDIARIES. No later than the sixth month
anniversary of the Closing Date, the Borrower shall (and shall at all times
thereafter) either:

            (a) take all actions permitted under the Credit Agreement that are
necessary to cause each Foreign Subsidiary of the Borrower to become a direct or
indirect Subsidiary of Guardian; or

            (b) deliver to the Collateral Agent, each in form and substance
reasonably satisfactory to the Collateral Agent, (i) a duly executed pledge or
security agreement effectively pledging in favor of the Collateral Agent the
Pledged Stock (other than Excluded Equity) of each Foreign Subsidiary that is
directly owned by the Borrower or any other Grantor (except Guardian) on such
date, which pledge or security agreement shall be governed by the local law of
the jurisdiction of such Foreign Subsidiary, (ii) to the extent not already
delivered to the Collateral Agent, share certificates representing all of the
Pledged Stock of such Foreign Subsidiary being pledged pursuant to this
Agreement (not including any Excluded Equity of such Foreign Subsidiary) and
stock powers for such share certificates executed in blank, and (iii) a
favorable opinion of appropriate foreign counsel to the Loan Parties, addressed
to the Collateral Agent and the Lenders and addressing such matters as any
Lender through the Collateral Agent may reasonably request.

                                   ARTICLE V

                               REMEDIAL PROVISIONS

            SECTION 5.1 CODE AND OTHER REMEDIES. During the continuance of an
Event of Default, the Collateral Agent may in accordance with the terms of the
Credit Agreement and subject to the Intercreditor Agreement exercise, in
addition to all other rights and remedies granted to it in this Agreement and in
any other instrument or agreement securing, evidencing or relating to the
Secured Obligations, all rights and remedies of a secured party under the UCC or
any other applicable law. Without limiting the generality of the foregoing, the
Collateral Agent, without demand of performance or other demand, presentment,
protest, advertisement or notice of any kind (except any notice required by law
referred to below) to or upon any Grantor or any other Person (all and each of
which demands, defenses, advertisements and notices are hereby waived), may in
such circumstances, in accordance with the terms of the Credit Agreement and
subject to the Intercreditor Agreement, forthwith collect, receive, appropriate
and realize upon any Collateral, and may forthwith sell, lease, assign, give
option or options to purchase, or otherwise dispose of and deliver any
Collateral (or contract to do any of the foregoing), in one or more parcels at
public or private sale or sales, at any exchange, broker's board or office of
the Collateral Agent or any Lender or elsewhere upon such terms and conditions
as it may deem advisable and at such prices as it may deem best, for cash or on
credit or for future delivery without assumption of any credit risk. In
accordance with the terms of the Credit Agreement and subject to the terms of
the Intercreditor Agreement, the Collateral Agent shall have the right upon any
such public sale or sales, and, to the extent permitted by the UCC and other
applicable law,

                                       19

upon any such private sale or sales, to purchase the whole or any part of the
Collateral so sold, free of any right or equity of redemption of any Grantor,
which right or equity is hereby waived and released. Each Grantor further
agrees, at the Collateral Agent's request, to assemble the Collateral and make
it available to the Collateral Agent at places that the Collateral Agent shall
reasonably select, whether at such Grantor's premises or elsewhere. In
accordance with the terms of the Credit Agreement and subject to the terms of
the Intercreditor Agreement, the Collateral Agent shall apply the net proceeds
of any action taken by it pursuant to this Section 5.1, after deducting all
reasonable costs and expenses of every kind incurred in connection therewith or
incidental to the care or safekeeping of any Collateral or in any way relating
to the Collateral or the rights of the Collateral Agent and any other Secured
Party hereunder, including reasonable attorneys' fees and disbursements, to the
payment in whole or in part of the Secured Obligations, in such order as the
Credit Agreement shall prescribe, and only after such application and after the
payment by the Collateral Agent of any other amount required by any provision of
law, need the Collateral Agent account for the surplus, if any, to any Grantor.
To the extent permitted by applicable law, each Grantor waives all claims,
damages and demands it may acquire against the Collateral Agent or any other
Secured Party arising out of the exercise by them of any rights hereunder. If
any notice of a proposed sale or other disposition of Collateral shall be
required by law, such notice shall be deemed reasonable and proper if given at
least 10 days before such sale or other disposition.

            SECTION 5.2 ACCOUNTS AND PAYMENTS IN RESPECT OF GENERAL INTANGIBLES

            (a) Subject to the terms of the Intercreditor Agreement, in addition
to, and not in substitution for, any similar requirement in the Credit
Agreement, if required by the Collateral Agent at any time during the
continuance of an Event of Default, any payment of Accounts or payment in
respect of General Intangibles, when collected by any Grantor, shall be
forthwith (and, in any event, within two Business Days) deposited by such
Grantor in the exact form received, duly indorsed by such Grantor to the
Collateral Agent, in an Approved Deposit Account or a Cash Collateral Account,
subject to withdrawal by the Collateral Agent as provided in Section 5.4
(Proceeds to be Turned Over To Collateral Agent). Subject to the terms of the
Intercreditor Agreement, until so turned over or turned over, such payment shall
be held by such Grantor in trust for the Collateral Agent, segregated from other
funds of such Grantor. Each such deposit of Proceeds of Accounts and payments in
respect of General Intangibles shall be accompanied by a report identifying in
reasonable detail the nature and source of the payments included in the deposit.

            (b) Subject to the terms of the Intercreditor Agreement, at the
Collateral Agent's request, during the continuance of an Event of Default, each
Grantor shall deliver to the Collateral Agent all original and other documents
evidencing, and relating to, the agreements and transactions that gave rise to
the Accounts or payments in respect of General Intangibles, including all
original orders, invoices and shipping receipts.

            (c) Subject to the terms of the Intercreditor Agreement, the
Collateral Agent may, without notice, at any time during the continuance of an
Event of Default, limit or terminate the authority of a Grantor to collect its
Accounts or amounts due under General Intangibles or any thereof.

            (d) Subject to the terms of the Intercreditor Agreement, the
Collateral Agent in its own name or in the name of others may at any time during
the continuance of an Event of Default communicate with Account Debtors to
verify with them to the Collateral Agent's

satisfaction the existence, amount and terms of any Account or amounts due under
any General Intangible.

            (e) Subject to the terms of the Intercreditor Agreement, upon the
request of the Collateral Agent at any time during the continuance of an Event
of Default, each Grantor shall notify Account Debtors that the Accounts or
General Intangibles have been collaterally assigned to the Collateral Agent and
that payments in respect thereof shall be made directly to the Collateral Agent.
In addition, subject to the Intercreditor Agreement, the Collateral Agent may at
any time during the continuance of an Event of Default enforce such Grantor's
rights against such Account Debtors and obligors of General Intangibles.

            (f) Anything herein to the contrary notwithstanding, each Grantor
shall remain liable under each of the Accounts and payments in respect of
General Intangibles to observe and perform all the conditions and obligations to
be observed and performed by it thereunder, all in accordance with the terms of
any agreement giving rise thereto. Neither the Collateral Agent nor any other
Secured Party shall have any obligation or liability under any agreement giving
rise to an Account or a payment in respect of a General Intangible by reason of
or arising out of this Agreement or the receipt by the Collateral Agent nor any
other Secured Party of any payment relating thereto, nor shall the Collateral
Agent nor any other Secured Party be obligated in any manner to perform any
obligation of any Grantor under or pursuant to any agreement giving rise to an
Account or a payment in respect of a General Intangible, to make any payment, to
make any inquiry as to the nature or the sufficiency of any payment received by
it or as to the sufficiency of any performance by any party thereunder, to
present or file any claim, to take any action to enforce any performance or to
collect the payment of any amounts that may have been assigned to it or to which
it may be entitled at any time or times.

            SECTION 5.3 PLEDGED COLLATERAL

            (a) Subject to the terms of the Intercreditor Agreement, during the
continuance of an Event of Default, upon notice by the Collateral Agent to the
relevant Grantor or Grantors, (i) the Collateral Agent shall have the right to
receive any Proceeds of the Pledged Collateral and make application thereof to
the Obligations in the order set forth in the Credit Agreement and (ii) the
Collateral Agent or its nominee may exercise (A) any voting, consent, corporate
and other right pertaining to the Pledged Collateral at any meeting of
shareholders, partners or members, as the case may be, of the relevant issuer or
issuers of Pledged Collateral or otherwise and (B) any right of conversion,
exchange and subscription and any other right, privilege or option pertaining to
the Pledged Collateral as if it were the absolute owner thereof (including the
right to exchange at its discretion any of the Pledged Collateral upon the
merger, amalgamation, consolidation, reorganization, recapitalization or other
fundamental change in the corporate or equivalent structure of any issuer of
Pledged Stock, the right to deposit and deliver any Pledged Collateral with any
committee, depositary, transfer agent, registrar or other designated agency upon
such terms and conditions as the Collateral Agent may determine), all without
liability except to account for property actually received by it; provided,
however, that the Collateral Agent shall have no duty to any Grantor to exercise
any such right, privilege or option and shall not be responsible for any failure
to do so or delay in so doing.

            (b) Subject to the terms of the Intercreditor Agreement, in order to
permit the Collateral Agent to exercise the voting and other consensual rights
that it may be entitled to exercise pursuant hereto and to receive all dividends
and other distributions that it may be entitled to receive hereunder, (i) each
Grantor shall promptly execute and deliver (or cause to be executed

                                                   PLEDGE AND SECURITY AGREEMENT
                                                          AMKOR TECHNOLOGY, INC.

and delivered) to the Collateral Agent all such proxies, dividend payment orders
and other instruments as the Collateral Agent may from time to time reasonably
request and (ii) without limiting the effect of clause (i) above, such Grantor
hereby grants to the Collateral Agent an irrevocable proxy to vote all or any
part of the Pledged Collateral and to exercise all other rights, powers,
privileges and remedies to which a holder of the Pledged Collateral would be
entitled (including giving or withholding written consents of shareholders,
partners or members, as the case may be, calling special meetings of
shareholders, partners or members, as the case may be, and voting at such
meetings), which proxy shall be effective, automatically and without the
necessity of any action (including any transfer of any Pledged Collateral on the
record books of the issuer thereof) by any other person (including the issuer of
such Pledged Collateral or any officer or agent thereof) during the continuance
of an Event of Default and which proxy shall only terminate upon the payment in
full of the Secured Obligations.

            (c) Each Grantor hereby expressly authorizes and instructs each
issuer of any Pledged Collateral pledged hereunder by such Grantor to (i) comply
with any instruction received by it from the Collateral Agent in writing that
(A) states that an Event of Default has occurred and is continuing and (B) is
otherwise in accordance with the terms of this Agreement, without any other or
further instructions from such Grantor, and each Grantor agrees that such issuer
shall be fully protected in so complying and (ii) unless otherwise expressly
permitted hereby, pay any dividend or other payment with respect to the Pledged
Collateral directly to the Collateral Agent.

            SECTION 5.4 PROCEEDS TO BE TURNED OVER TO COLLATERAL AGENT. Subject
to the terms of the Intercreditor Agreement, unless otherwise expressly provided
in the Credit Agreement, all Proceeds received by the Collateral Agent hereunder
in cash or Cash Equivalents shall be held by the Collateral Agent in a Cash
Collateral Account. All Proceeds while held by the Collateral Agent in a Cash
Collateral Account (or by such Grantor in trust for the Collateral Agent) shall,
subject to the Intercreditor Agreement, continue to be held as collateral
security for the Secured Obligations and shall not constitute payment thereof
until applied as provided in the Credit Agreement.

            SECTION 5.5 REGISTRATION RIGHTS

            (a) Each Grantor recognizes that the Collateral Agent may be unable
to effect a public sale of any Pledged Collateral by reason of certain
prohibitions contained in the Securities Act and applicable state securities
laws or otherwise or may determine that a public sale is impracticable or not
commercially reasonable and, accordingly, may resort to one or more private
sales thereof to a restricted group of purchasers that shall be obliged to
agree, among other things, to acquire such securities for their own account for
investment and not with a view to the distribution or resale thereof. Each
Grantor acknowledges and agrees that any such private sale may result in prices
and other terms less favorable than if such sale were a public sale and,
notwithstanding such circumstances, agrees that any such private sale shall be
deemed to have been made in a commercially reasonable manner. The Collateral
Agent shall be under no obligation to delay a sale of any Pledged Collateral for
the period of time necessary to permit the issuer thereof to register such
securities for public sale under the Securities Act, or under applicable state
securities laws, even if such issuer would agree to do so.

            (b) Each Grantor agrees to use its commercially reasonable efforts
to do or cause to be done all such other acts as may be necessary to make such
sale or sales of all or any portion of the Pledged Collateral pursuant to this
Section 5.5 valid and binding and in compliance

with all other applicable Requirements of Law. Each Grantor further agrees that
a breach of any covenant contained in this Section 5.5 will cause irreparable
injury to the Collateral Agent and other Secured Parties, that the Collateral
Agent and the other Secured Parties have no adequate remedy at law in respect of
such breach and, as a consequence, that each and every covenant contained in
this Section 5.5 shall be specifically enforceable against such Grantor, and
such Grantor hereby waives and agrees not to assert any defense against an
action for specific performance of such covenants except for a defense that no
Event of Default has occurred under the Credit Agreement.

            SECTION 5.6 DEFICIENCY. Each Grantor shall remain liable for any
deficiency if the proceeds of any sale or other disposition of the Collateral
are insufficient to pay the Secured Obligations and the fees and disbursements
of any attorney employed by the Collateral Agent or any other Secured Party to
collect such deficiency.

                                   ARTICLE VI

                              THE COLLATERAL AGENT

            SECTION 6.1 COLLATERAL AGENT'S APPOINTMENT AS ATTORNEY-IN-FACT

            (a) Each Grantor hereby irrevocably constitutes and appoints the
Collateral Agent and any officer or agent thereof, with full power of
substitution, as its true and lawful attorney-in-fact with full irrevocable
power and authority in the place and stead of such Grantor and in the name of
such Grantor or in its own name, for the purpose of carrying out the terms of
this Agreement, to take any appropriate action and to execute any document or
instrument that may be necessary or desirable to accomplish the purposes of this
Agreement, and, without limiting the generality of the foregoing, each Grantor
hereby gives the Collateral Agent the power and right, on behalf of such
Grantor, without notice to or assent by such Grantor, to do any of the
following:

            (i) in the name of such Grantor or its own name, or otherwise, take
      possession of and indorse and collect any check, draft, note, acceptance
      or other instrument for the payment of moneys due under any Account or
      General Intangible or with respect to any other Collateral and file any
      claim or take any other action or proceeding in any court of law or equity
      or otherwise deemed appropriate by the Collateral Agent for the purpose of
      collecting any such moneys due under any Account or General Intangible or
      with respect to any other Collateral whenever payable;

            (ii) in the case of any Intellectual Property, execute and deliver,
      and have recorded, any agreement, instrument, document or paper as the
      Collateral Agent may request to evidence the Collateral Agent's security
      interest in such Intellectual Property and the goodwill and General
      Intangibles of such Grantor relating thereto or represented thereby;

            (iii) pay or discharge taxes and Liens levied or placed on or
      threatened against the Collateral, effect any repair or pay any insurance
      called for by the terms of this Agreement (including all or any part of
      the premiums therefor and the costs thereof);

                                                          AMKOR TECHNOLOGY, INC.

            (iv) execute, in connection with any sale provided for in Section
      5.1 (Code and Other Remedies) or 5.5 (Registration Rights), any
      endorsement, assignment or other instrument of conveyance or transfer with
      respect to the Collateral; or

            (v) (A) direct any party liable for any payment under any Collateral
      to make payment of any moneys due or to become due thereunder directly to
      the Collateral Agent or as the Collateral Agent shall direct, (B) ask or
      demand for, collect, and receive payment of and receipt for, any moneys,
      claims and other amounts due or to become due at any time in respect of or
      arising out of any Collateral, (C) sign and indorse any invoice, freight
      or express bill, bill of lading, storage or warehouse receipt, draft
      against debtors, assignment, verification, notice and other document in
      connection with any Collateral, (D) commence and prosecute any suit,
      action or proceeding at law or in equity in any court of competent
      jurisdiction to collect any Collateral and to enforce any other right in
      respect of any Collateral, (E) defend any suit, action or proceeding
      brought against such Grantor with respect to any Collateral, (F) settle,
      compromise or adjust any such suit, action or proceeding and, in
      connection therewith, give such discharges or releases as the Collateral
      Agent may deem appropriate, (G) assign any Copyright, Patent or Trademark
      (along with the goodwill of the business to which any such Trademark
      pertains) throughout the world for such term or terms, on such conditions,
      and in such manner as the Collateral Agent shall in its sole discretion
      determine, including the execution and filing of any document necessary to
      effectuate or record such assignment and (H) generally, sell, transfer,
      pledge and make any agreement with respect to or otherwise deal with any
      Collateral as fully and completely as though the Collateral Agent were the
      absolute owner thereof for all purposes, and do, at the Collateral Agent's
      option and such Grantor's expense, at any time, or from time to time, all
      acts and things that the Collateral Agent deems necessary to protect,
      preserve or realize upon the Collateral and the Collateral Agent's and the
      other Secured Parties' security interests therein and to effect the intent
      of this Agreement, all as fully and effectively as such Grantor might do.

Anything in this clause (a) to the contrary notwithstanding, the Collateral
Agent agrees that it shall not exercise any right under the power of attorney
provided for in this clause (a) unless an Event of Default shall be continuing.

            (b) If any Grantor fails to perform or comply with any of its
agreements contained herein, the Collateral Agent, at its option, but without
any obligation so to do, may perform or comply, or otherwise cause performance
or compliance, with such agreement.

            (c) The expenses of the Collateral Agent incurred in connection with
actions undertaken as provided in this Section 6.1, together with interest
thereon at a rate per annum equal to the sum of the Base Rate in effect from
time to time plus the Applicable Margin, from the date of payment by the
Collateral Agent to the date reimbursed by the relevant Grantor, shall be
payable by such Grantor to the Collateral Agent on demand.

            (d) Each Grantor hereby ratifies all that said attorneys shall
lawfully do or cause to be done by virtue hereof. All powers, authorizations and
agencies contained in this Agreement are coupled with an interest and are
irrevocable until this Agreement is terminated and the security interests
created hereby are released.

            SECTION 6.2 DUTY OF COLLATERAL AGENT. The Collateral Agent's sole
duty with respect to the custody, safekeeping and physical preservation of the
Collateral in its possession

shall be to deal with it in the same manner as the Collateral Agent deals with
similar property for its own account. Neither the Collateral Agent, any other
Secured Party nor any of their respective officers, directors, employees or
agents shall be liable for failure to demand, collect or realize upon any
Collateral or for any delay in doing so or shall be under any obligation to sell
or otherwise dispose of any Collateral upon the request of any Grantor or any
other Person or to take any other action whatsoever with regard to any
Collateral. The powers conferred on the Collateral Agent hereunder are solely to
protect the Collateral Agent's interest in the Collateral and shall not impose
any duty upon the Collateral Agent or any other Secured Party to exercise any
such powers. The Collateral Agent and the other Secured Parties shall be
accountable only for amounts that they actually receive as a result of the
exercise of such powers, and neither they nor any of their respective officers,
directors, employees or agents shall be responsible to any Grantor for any act
or failure to act hereunder, except for their own gross negligence or willful
misconduct.

            SECTION 6.3 AUTHORIZATION OF FINANCING STATEMENTS. Subject to the
terms of the Intercreditor Agreement, each Grantor authorizes the Collateral
Agent and its Affiliates, counsel and other representatives, at any time and
from time to time, to file or record financing statements, amendments to
financing statements, and other filing or recording documents or instruments
with respect to the Collateral in such form and in such offices as the
Collateral Agent reasonably determines appropriate to perfect the security
interests of the Collateral Agent under this Agreement, and such financing
statements and amendments may describe the Collateral covered thereby as "all
assets of the debtor", "all personal property of the debtor" or words of similar
effect. Subject to the terms of the Intercreditor Agreement, each Grantor hereby
also authorizes the Collateral Agent and its Affiliates, counsel and other
representatives, at any time and from time to time, to file continuation
statements with respect to previously filed financing statements. A photographic
or other reproduction of this Agreement shall be sufficient as a financing
statement or other filing or recording document or instrument for filing or
recording in any jurisdiction.

            SECTION 6.4 AUTHORITY OF COLLATERAL AGENT. Each Grantor acknowledges
that the rights and responsibilities of the Collateral Agent under this
Agreement with respect to any action taken by the Collateral Agent or the
exercise or non-exercise by the Collateral Agent of any option, voting right,
request, judgment or other right or remedy provided for herein or resulting or
arising out of this Agreement shall, as between the Collateral Agent and the
other Secured Parties, be governed by the Credit Agreement and by such other
agreements with respect thereto as may exist from time to time among them, but,
as between the Collateral Agent and the Grantors, the Collateral Agent shall be
conclusively presumed to be acting as agent for the Collateral Agent and the
other Secured Parties with full and valid authority so to act or refrain from
acting, and no Grantor shall be under any obligation, or entitlement, to make
any inquiry respecting such authority. To the extent the Credit Agreement
conflicts with any other Loan Document with regard to the authority of the
Collateral Agent, the Credit Agreement shall control.

                                   ARTICLE VII

                                  MISCELLANEOUS

            SECTION 7.1 AMENDMENTS IN WRITING. None of the terms or provisions
of this Agreement may be waived, amended, supplemented or otherwise modified
except in accordance with Section 8.1 (Amendments, Waivers, Etc.) of the Credit
Agreement; provided, however, that annexes to this Agreement may be supplemented
(but no existing provisions may be modified and no Collateral may be released)
through Pledge Amendments and Joinder Agreements, in substantially the form of
Annex 2 (Form of Pledge Amendment) and Annex 3 (Form of Joinder Agreement)
respectively, in each case duly executed by the Collateral Agent and each
Grantor directly affected thereby.

            SECTION 7.2 NOTICES. All notices, requests and demands to or upon
the Collateral Agent or any Grantor hereunder shall be effected in the manner
provided for in Section 8.8 (Notices, Etc.) of the Credit Agreement; provided,
however, that any such notice, request or demand to or upon any Grantor shall be
addressed to the Borrower's notice address set forth in such Section 8.8.

            SECTION 7.3 NO WAIVER BY COURSE OF CONDUCT; CUMULATIVE REMEDIES.
Neither the Collateral Agent nor any other Secured Party shall by any act
(except by a written instrument pursuant to Section 7.1 (Amendments in
Writing)), delay, indulgence, omission or otherwise be deemed to have waived any
right or remedy hereunder or to have acquiesced in any Default or Event of
Default. No failure to exercise, nor any delay in exercising, on the part of the
Collateral Agent or any other Secured Party, any right, power or privilege
hereunder shall operate as a waiver thereof. No single or partial exercise of
any right, power or privilege hereunder shall preclude any other or further
exercise thereof or the exercise of any other right, power or privilege. A
waiver by the Collateral Agent or any other Secured Party of any right or remedy
hereunder on any one occasion shall not be construed as a bar to any right or
remedy that the Collateral Agent or such other Secured Party would otherwise
have on any future occasion. The rights and remedies herein provided are
cumulative, may be exercised singly or concurrently and are not exclusive of any
other rights or remedies provided by law.

            SECTION 7.4 SUCCESSORS AND ASSIGNS. This Agreement shall be binding
upon the successors and assigns of each Grantor and shall inure to the benefit
of the Collateral Agent and each other Secured Party and their successors and
assigns; provided, however, that no Grantor may assign, transfer or delegate any
of its rights or obligations under this Agreement without the prior written
consent of the Collateral Agent.

            SECTION 7.5 COUNTERPARTS. This Agreement may be executed by one or
more of the parties to this Agreement on any number of separate counterparts
(including by telecopy), each of which when so executed shall be deemed to be an
original and all of which taken together shall constitute one and the same
agreement. Signature pages may be detached from multiple counterparts and
attached to a single counterpart so that all signature pages are attached to the
same document. Delivery of an executed counterpart by telecopy shall be
effective as delivery of a manually executed counterpart.

            SECTION 7.6 SEVERABILITY. 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 provisions hereof, and

                                       26

any such prohibition or unenforceability in any jurisdiction shall not
invalidate or render unenforceable such provision in any other jurisdiction.

            SECTION 7.7 SECTION HEADINGS. The Article and Section titles
contained in this Agreement are, and shall be, without substantive meaning or
content of any kind whatsoever and are not part of the agreement of the parties
hereto.

            SECTION 7.8 ENTIRE AGREEMENT. This Agreement together with the other
Loan Documents represents the entire agreement of the parties and supersedes all
prior agreements and understandings relating to the subject matter hereof.

            SECTION 7.9 GOVERNING LAW. This Agreement and the rights and
obligations of the parties hereto shall be governed by, and construed and
interpreted in accordance with, the law of the State of New York.

            SECTION 7.10 ADDITIONAL GRANTORS. If, pursuant to Section 5.20
(Additional Collateral and Guarantees) of the Credit Agreement, the Borrower
shall be required to cause any Subsidiary that is not a Grantor to become a
Grantor hereunder, such Subsidiary shall execute and deliver to the Collateral
Agent a Joinder Agreement substantially in the form of Annex 3 (Form of Joinder
Agreement) and shall thereafter for all purposes be a party hereto and have the
same rights, benefits and obligations as a Grantor party hereto on the Closing
Date.

            SECTION 7.11 RELEASE OF COLLATERAL.

            (a) At the time provided in clause (b)(i) of Section 7.8 (Release of
Collateral and Subsidiary Guarantors) of the Credit Agreement, the Collateral
shall be released from the Lien created hereby and this Agreement and all
obligations (other than those expressly stated to survive such termination) of
the Collateral Agent and each Grantor hereunder shall terminate, all without
delivery of any instrument or performance of any act by any party, and all
rights to the Collateral shall revert to the Grantors. At the request and sole
expense of any Grantor following any such termination, the Collateral Agent
shall deliver to such Grantor any Collateral of such Grantor held by the
Collateral Agent hereunder and execute and deliver to such Grantor such
documents as such Grantor shall reasonably request to evidence such termination.

            (b) If the Collateral Agent shall be directed or permitted pursuant
to (i) clauses (a), (b)(ii) and (b)(iii) of Section 7.8 (Release of Collateral
and Subsidiary Guarantors) of the Credit Agreement or (ii) pursuant to the
Intercreditor Agreement, to release any Lien created hereby upon any Collateral
(including any Collateral sold or disposed of by any Grantor in a transaction
permitted by the Credit Agreement), such Collateral shall be released from the
Lien created hereby to the extent provided under, and subject to the terms and
conditions set forth in, Section 7.8 (Release of Collateral and Subsidiary
Guarantors) of the Credit Agreement. In connection therewith, the Collateral
Agent, at the request and sole expense of the Borrower, shall execute and
deliver to the Borrower all releases or other documents, including, without
limitation, UCC termination statements, reasonably necessary or desirable in
connection with the release of the Lien created hereby on such Collateral. At
the request and sole expense of the Borrower, a Grantor shall be released from
its obligations hereunder in the event that all the capital stock of such
Grantor shall be so sold or disposed; provided, however, that the Borrower shall
have delivered to the Collateral Agent, at least ten Business Days prior to the
date of the proposed release, a written request for release identifying the
relevant Grantor and the terms of the sale or other disposition in reasonable
detail, including the price thereof and any expenses in connection

therewith, together with a certification by the Borrower in form and substance
satisfactory to the Collateral Agent stating that such transaction is in
compliance with the Credit Agreement and the other Loan Documents.

            SECTION 7.12 REINSTATEMENT. Each Grantor further agrees that, if any
payment made by any Loan Party or other Person and applied to the Obligations is
at any time annulled, avoided, set aside, rescinded, invalidated, declared to be
fraudulent or preferential or otherwise required to be refunded or repaid, or
the proceeds of Collateral are required to be returned by any Secured Party to
such Loan Party, its estate, trustee, receiver or any other party, including any
Grantor, under any bankruptcy law, state or federal law, common law or equitable
cause, then, to the extent of such payment or repayment, any Lien or other
Collateral securing such liability shall be and remain in full force and effect,
as fully as if such payment had never been made or, if prior thereto the Lien
granted hereby or other Collateral securing such liability hereunder shall have
been released or terminated by virtue of such cancellation or surrender), such
Lien or other Collateral shall be reinstated in full force and effect, and such
prior cancellation or surrender shall not diminish, release, discharge, impair
or otherwise affect any Lien or other Collateral securing the obligations of any
Grantor in respect of the amount of such payment.

                                                         _____________ __, 20__

Ladies and Gentlemen:

            The undersigned ___________________ (the "Pledgor") together with
certain of its affiliates are party to a Second Lien Pledge and Security
Agreement dated October 27, 2004 in favor of Citicorp North America, Inc., as
agent for the Secured Parties referred to therein (the "Pledgee" and such
agreement the "Pledge and Security Agreement") pursuant to which a security
interest is granted by the Pledgor in all present and future Assets (hereinafter
defined) in Account No. _______ of the Pledgor (the "Pledge").

            In connection therewith, the Pledgor hereby instructs you (the
"Approved Securities Intermediary") to do all of the following:

      1.    maintain the Account, as "_________________- Citicorp North America,
            Inc. Control Account";

      2.    hold in the Account the assets, including, without limitation, all
            financial assets, securities, security entitlements and all other
            property and rights now or hereafter received in such Account
            (collectively the "Assets"), including, without limitation, those
            assets listed on Schedule A (List of Assets) attached hereto and
            made a part hereof;

      3.    provide to the Pledgee, with a duplicate copy to the Pledgor, a
            monthly statement of Assets and a confirmation statement of each
            transaction effected in the Account after such transaction is
            effected; and

      4.    honor only the instructions or entitlement orders (within the
            meaning of Section 8-102 of the UCC (as defined below) (the
            "Entitlement Orders") in regard to or in connection with the Account
            given by an Authorized Officer of the Pledgee, except as provided in
            the following sentence. Until such time as the Pledgee gives a
            written notice in the form of Exhibit A hereto to the Approved
            Securities Intermediary that the Pledgor's rights under this
            sentence have been terminated (on which notice the Approved
            Securities Intermediary may rely exclusively), the Pledgor acting
            through an Authorized Officer may (a) exercise any voting right that
            it may have with respect to any Asset, (b) give Entitlement Orders
            and otherwise give instructions to enter into purchase or sale
            transactions in the Account and (c) withdraw and receive for its own
            use all regularly scheduled interest [and dividends] paid with
            respect to the Assets [and all cash proceeds of any sale of Assets]
            ("Permitted Withdrawals"); provided, however,

                                      A1-1
<PAGE>

            that, unless the Pledgee has consented to the specific transaction,
            the Pledgor shall not instruct the Approved Securities Intermediary
            to deliver and, except as may be required by law or by court order,
            the Approved Securities Intermediary shall not deliver, cash,
            securities, or proceeds from the sale of, or distributions on, such
            securities out of the Account to the Pledgor or to any other person
            or entity other than Permitted Withdrawals.

            By its signature below, the Approved Securities Intermediary agrees
to comply with the Entitlement Orders and instructions of an Authorized Officer
of the Pledgee (including, without limitation, any instruction with respect to
sales, trades, transfers and withdrawals of cash or other of the Assets) without
the further consent of the Pledgor or any other person (it being understood and
agreed by the Pledgor that the Approved Securities Intermediary shall have no
duty or obligation whatsoever to have knowledge of the terms of the Pledge and
Security Agreement or to determine whether or not an event of default exists
thereunder). The Pledgor hereby agrees to indemnify and hold harmless the
Approved Securities Intermediary, its affiliates, officers and employees from
and against all claims, causes of action, liabilities, lawsuits, demands and
damages, including, without limitation, all court costs and reasonable
attorney's fees, that may result by reason of the Approved Securities
Intermediary complying with such instructions of the Pledgee.

            The Authorized Officer of the Pledgee who shall give oral
instructions hereunder shall confirm the same in writing to the Approved
Securities Intermediary within five days after such oral instructions are given.

            For the purpose of this Agreement, the term "Authorized Officer of
the Pledgor" shall refer in the singular to ___________________ or
___________________ (each of whom is, on the date hereof, an officer or director
of the Pledgor) and "Authorized Officer of the Pledgee" shall refer in the
singular to any person who is a vice president or managing director of the
Pledgee. In the event that the Pledgor shall find it advisable to designate a
replacement for any of its Authorized Officers, written notice of any such
replacement shall be given to the Approved Securities Intermediary and the
Pledgee.

            Except with respect to the obligations and duties as set forth
herein, this Agreement shall not impose or create any obligation or duty upon
the Approved Securities Intermediary greater than or in addition to the
customary and usual obligations and duties of the Approved Securities
Intermediary to the Pledgor.

            As long as the Assets are pledged to the Pledgee, (i) the Approved
Securities Intermediary shall not invade the Assets to cover margin debits or
calls in any other account of the Pledgor and (ii) the Approved Securities
Intermediary agrees that, except for liens resulting from customary commissions,
fees, or charges based upon transactions in the Account, it subordinates in
favor of the Pledgee any security interest, lien or right of setoff the Approved
Securities Intermediary may have. The Approved Securities Intermediary
acknowledges that it has not received notice of any other security interest in
the Account or the Assets. In the event any such notice is received, the
Approved Securities Intermediary shall promptly notify the Pledgee. The Pledgor
herein represents that the Assets are free and clear of any lien or encumbrance
and agrees that, with the exception of the security interest granted to the
Pledgee, no lien or encumbrance shall be placed by it on the Assets without the
express written consent of both the Pledgee and the Approved Securities
Intermediary.

                                      A1-2
<PAGE>

            This Agreement shall be binding upon and inure to the benefit of the
parties hereto and their respective successors and assigns and it and the rights
and obligations of the parties hereto shall be governed by, and construed and
interpreted in accordance with, and the law of the Approved Securities
Intermediary's jurisdiction for the purposes of Section 8-110 of the Uniform
Commercial Code in effect in the State of New York (the "UCC") shall be, the law
of the State of New York.

            The Approved Securities Intermediary shall treat all property at any
time held by the Approved Securities Intermediary in the Account as Financial
Assets within the meaning of the UCC. The Approved Securities Intermediary
acknowledges that this Agreement constitutes written notification to the
Approved Securities Intermediary, pursuant to the UCC and any applicable federal
regulations for the Federal Reserve Book Entry System, of the Pledgee's security
interest in the Assets. The Pledgor, Pledgee and Approved Securities
Intermediary are entering into this Agreement to provide for the Pledgee's
control of the Assets and to confirm the first priority of the Pledgee's
security interest in the Assets.

            If any term or provision of this Agreement is determined to be
invalid or unenforceable, the remainder of this Agreement shall be construed in
all respects as if the invalid or unenforceable term or provision were omitted.
This Agreement may not be altered or amended in any manner without the express
written consent of the Pledgor, the Pledgee and the Approved Securities
Intermediary. This Agreement may be executed in any number of counterparts, all
of which shall constitute one original agreement.

            The Pledgor hereby agrees to indemnify and hold you, your directors,
officers, agents and employees harmless against all claims, causes of action,
liabilities, lawsuits, demands and damages, including, without limitation, all
court costs and reasonable attorney fees, in each case in any way related to or
arising out of or in connection with this letter agreement or any action taken
or not taken pursuant hereto, except to the extent caused by your gross
negligence or willful misconduct.

            This Agreement may be terminated by the Approved Securities
Intermediary upon 30 day's prior written notice to the Pledgor and the Pledgee.
Upon expiration of such 30-day period, the Approved Securities Intermediary
shall be under no further obligation except to hold the Assets in accordance
with the terms of this Agreement, pending receipt of written instructions from
the Pledgor and the Pledgee, jointly, regarding the further disposition of the
pledged Assets.

            The Pledgor acknowledges that this Agreement supplements any
existing agreement of the Pledgor with the Approved Securities Intermediary and,
except as expressly provided herein, is in no way intended to abridge any right
that the Approved Securities Intermediary might otherwise have.

            IN WITNESS WHEREOF, the Pledgor and the Pledgee have caused this
Agreement to be executed by their duly authorized officers all as of the date
