standing under the laws of the jurisdiction identified as its jurisdiction of
organization in its Perfection Certificate.

          (b) The Lien Grantor has good and marketable title to all its
Collateral (subject to exceptions that are, in the aggregate, not material),
free and clear of any Lien other than Permitted Liens.

          (c) The Lien Grantor has not performed any acts that might prevent the
Collateral Agent from enforcing any of the provisions of the Security Documents
or that would limit the Collateral Agent in any such enforcement. No financing
statement, security agreement, mortgage or similar or equivalent document or
instrument covering all or part of the Collateral owned by such Lien Grantor is
on file or of record in any jurisdiction in which such filing or recording would
be effective to perfect or record a Lien on such Collateral, except financing
statements, mortgages or other similar or equivalent documents with respect to
Permitted Liens. After the Effective Date, no Collateral owned by such Lien
Grantor will be in the possession or under the control of any other Person
having a Lien thereon, other than a Permitted Lien.

the filing made at such filing office to perfect the Transaction Liens on the
Collateral.

          (f) When UCC financing statements describing the Collateral as set
forth in the Lien Grantor's Perfection Certificate have been filed in the
offices specified in the Perfection Certificate, the Transaction Liens will
constitute perfected security interests in the Collateral owned by the Lien
Grantor to the extent that a security interest therein may be perfected by
filing pursuant to the UCC, prior to all Liens and rights of others therein
except Permitted Liens. Except for the filing of such UCC financing statements,
no registration, recordation or filing with any governmental body, agency or
official is required in connection with the execution or delivery of the
Security Documents or is necessary for the validity or enforceability thereof or
for the perfection of the Transaction Liens pursuant to the UCC or for the
enforcement of the Transaction Liens pursuant to the UCC.

          (g) The Lien Grantor has taken, and will continue to take, all actions

proceeds in respect of Pledged Receivables may be deposited.

          (a) The Lien Grantor will, from time to time, at its own expense,
execute, deliver, authorize, file and record any statement, assignment,
instrument, document, agreement or other paper and take any other action
(including (x) any filing of financing or continuation statements under the UCC,
(y) at any time when the Effective Date Receivables Financing shall have
terminated and been paid in full and not been replaced with another Receivables
Financing on terms satisfactory to the Administrative Agent, causing any
lockbox, concentration or similar account into which payments with respect to
Receivables then owned by the Lien Grantor will be received to be subjected to
Blocked Account Agreements and (z) at any time when the Effective Date
Receivables Financing shall have terminated and been replaced with another
Receivables Financing on terms satisfactory to the Administrative Agent, causing
the appropriate parties to such replacement Receivables Financing to execute an
intercreditor agreement that is substantially identical to the Intercreditor
Agreement) that from time to time may be reasonably necessary or desirable, or
that the Collateral Agent may reasonably request, in order to:

          (i) create, preserve, perfect, confirm or validate the Transaction
Liens on the Collateral;

          (ii) enable the Collateral Agent and the other Secured Parties to
obtain the full benefits of the Security Documents; or

          (iii) enable the Collateral Agent to exercise and enforce any of its
rights, powers and remedies with respect to any of the Collateral.

To the extent permitted by applicable law, the Lien Grantor authorizes the
Collateral Agent to execute and file such financing statements or continuation
statements without the Lien Grantor's signature appearing thereon. The
Collateral Agent agrees to provide the Lien Grantor with copies of any such
financing statements and continuation statements. The Lien Grantor agrees that a
carbon, photographic, photostatic or other reproduction of this Agreement or of
a financing statement is sufficient as a financing statement to the extent
permitted by law. The Lien Grantor constitutes the Collateral Agent its
attorney-in-fact to execute and file all filings required or so requested 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 all the Transaction Liens granted by the Lien Grantor terminate pursuant
to Section 12. The Borrower will pay the costs of, or incidental to, any
recording or filing of any financing or continuation statements or other
documents recorded or filed pursuant hereto.

          (b) The Lien Grantor will not (i) change its name or limited liability
company structure (or other form of organization), except to reorganize as a
Delaware corporation under the name "United States Steel Corporation", (ii)
change its location (determined as provided in UCC Section 9-307) or (iii)
except with respect to a Permitted Lien, become bound, as provided in Revised
UCC Section 9-203(d) or otherwise, by a security agreement entered into by
another Person, unless it shall have given the Collateral Agent prior notice
thereof and delivered an Opinion of Counsel with respect thereto in accordance
with Section 4(c).

          (c) At least 30 days before it takes any action contemplated by
Section 4(b), the Lien Grantor, at its own expense, will cause to be delivered
to the Collateral Agent an Opinion of Counsel, in form and substance reasonably
satisfactory to the Collateral Agent, to the effect that (i) all financing
statements and amendments or supplements thereto, continuation statements and
other documents required to be filed or recorded in order to perfect and protect
the Transaction Liens against all creditors of and purchasers from the Lien
Grantor after it takes such action (except any applicable continuation
statements specified in such Opinion of Counsel that are to be filed more than
six months after the date thereof) have been filed or recorded in each office
necessary for such purpose, (ii) all fees and taxes, if any, payable in
connection with such filings or recordations have been paid in full and (iii)
except as otherwise agreed by the Required Lenders, such action will not
adversely affect the perfection or priority of the Transaction Lien on any
Collateral to be owned by the Lien Grantor after it takes such action or the
accuracy of the Lien Grantor's representations and warranties herein relating to
such Collateral.

          (d) The Lien Grantor will not sell, lease, exchange, assign or
otherwise dispose of, or grant any option with respect to, any of its
Collateral; provided that the Lien Grantor may do any of the foregoing unless
(i) doing so would breach a covenant in the Credit Agreement or (ii) an Event of
Default shall have occurred and be continuing and the Collateral Agent shall
have notified the Lien Grantor that its right to do so is terminated, suspended
or otherwise limited. Concurrently with any sale or other disposition (except a
lease) permitted by the foregoing proviso, the Transaction Liens on the assets
sold or disposed of (but not in any Proceeds arising from such sale or
disposition)


will cease immediately without any action by the Collateral Agent or any other
Secured Party. The Collateral Agent will, at the Borrower's expense, execute and
deliver to the Lien Grantor such documents as the Lien Grantor shall reasonably
request to evidence the fact that any asset so sold or disposed of is no longer
subject to a Transaction Lien.

          (e) The Lien Grantor will, promptly upon request, provide to the
Collateral Agent all information and evidence concerning the Collateral that the
Collateral Agent may reasonably request from time to time to enable it to
enforce the provisions of the Security Documents.

          (f) From time to time upon request by the Collateral Agent, the Lien
Grantor will, at its own expense, cause to be delivered to the Secured Parties
an Opinion of Counsel satisfactory to the Collateral Agent as to such matters
relating to the transactions contemplated hereby as the Collateral Agent may
reasonably request.

          . (a) If and when required for purposes hereof, the Collateral Agent
will establish an account (the "Cash Collateral Account"), in the name and under
the exclusive control of the Collateral Agent, into which all amounts owned by
the Lien Grantor that are to be deposited therein pursuant to the Financing
Documents shall be deposited from time to time.

          (b) Within 30 days following the Effective Date (or such longer period
as the Borrower, the Collateral Agent and the Co-Collateral Agent may agree),
the Lien Grantor will cause Receivables SPV to have subjected all of its then
existing accounts (collectively, the "Existing Receivables SPV Accounts") to
Blocked Account Agreements, each of which Blocked Account Agreements shall, to
the extent the account subject thereto is a "Lock-Box Account" or "Concentration
Account" (each as defined in the Receivables Purchase Agreement), (i) by its
terms, first become effective immediately upon receipt by the "Lockbox Box" or
"Concentration Account Bank" (each as defined in the Receivables Purchase
Agreement) or other depositary bank at which such account is maintained (the
"Depositary Bank") of written notice from The Bank of Nova Scotia, as collateral
agent under the Effective Date Receivables Financing (the "Receivables
Collateral Agent"), specifying that the Effective Date Receivables Financing has
terminated and all monetary obligations in respect thereof have been satisfied
in full and that the blocked account agreement in effect with respect to such
"Lockbox Account" or "Concentration Account" (each as defined in the Receivables
Purchase Agreement) in connection with the Effective Date Receivables Financing
shall be terminated in accordance with its terms (or upon written notice from
the Collateral Agent to such effect, if (x) the Receivables Collateral Agent has
failed to deliver such notice within five Business Days of the date on which it
is initially obligated to do so pursuant to the Intercreditor Agreement, (y) the
Collateral Agent shall have delivered a Final Notification Request (as defined
in the Intercreditor Agreement), and (z) the Funding Agents (as defined in the
Intercreditor Agreement) have failed to comply, or to cause the Receivables
Collateral Agent to comply, with such Final Notification Request within three
Business Days of the date on which such Final Notification Request is effective
under the Intercreditor Agreement), (ii) by its terms, terminate upon receipt by
the Depositary Bank of written notice from the Collateral Agent to the effect
that the Effective Date Receivables Financing has been replaced with another
Receivables Financing on terms satisfactory to the Administrative Agent, such
that the accounts of Receivables SPV and the lockbox accounts of the Lien
Grantor may be subjected to blocked account agreements in connection with such
replacement Receivables Financing and (iii) expressly provide that its terms may
not be amended or modified without the consent of the Receivables Collateral
Agent.

          (c) If directed to do so by the Collateral Agent at any time when an
Event of Default has occurred and is continuing, the Borrower shall cause to be
deposited in the account referred to in clause (d) below, promptly upon receipt
thereof, (i) all payments received in respect of the Pledged Receivables and
(ii) all other Proceeds of the Collateral.

          (d) Within 30 days following the Effective Date, the Borrower shall
cause to be subjected to a Blocked Account Agreement any lockbox, concentration
or other account into which payments from Receivables SPV to the Borrower in
respect of the purchase price of Transferred Receivables may be received.

          (e) Unless (x) a Sweep Period shall have occurred and be continuing,
(y) an Event of Default shall have occurred and be continuing and the Required
Lenders shall have instructed the Collateral Agent to stop withdrawing amounts
from the Cash Collateral Account pursuant to this subsection or (z) the maturity
of the Loans (or other Secured Obligations) shall have been accelerated pursuant
to Article 7 of the Credit Agreement (or otherwise), the Collateral Agent shall
withdraw amounts from the Cash Collateral Account (other than amounts required
to be deposited in the Cash Collateral Account pursuant to Section 2.10(b) or
Section 5.12(b) of the Credit Agreement) and remit such amounts to, or as
directed by, the Borrower from time to time.

          (f) If an Event of Default shall have occurred and be continuing, the
Collateral Agent may (i) retain all cash and investments then held in the Cash
Collateral Account, (ii) liquidate any or all investments held therein


and/or (iii) withdraw any amounts held therein and apply such amounts as
provided in Section 7. Additionally, and without limiting the generality of the
foregoing, during any Sweep Period (i) all amounts held in the Cash Collateral
Account (other than amounts deposited therein pursuant to Section 2.05(j),
Section 2.10 (b) or Section 5.12(b) of the Credit Agreement as cash collateral
for the LC Exposure) shall be applied on a daily basis to the outstanding
principal balance of the Base Rate Loans or, if applicable, as provided in
Section 7 and (ii) following repayment in full of all outstanding Base Rate
Loans pursuant to clause (i), any remaining amounts held in the Cash Collateral
Account shall continue to be held in the Cash Collateral Account and (other than
amounts deposited therein pursuant to Section 2.05(j), Section 2.10(b) or
Section 5.12(b) of the Credit Agreement as cash collateral for the LC Exposure)
shall be applied to the outstanding principal balance of maturing Eurodollar
Loans upon expiration of the Interest Periods applicable thereto.

          (g) Funds held in the Cash Collateral Account may, until withdrawn or
otherwise applied pursuant hereto, be invested and reinvested in such Liquid
Investments as the Borrower shall request from time to time; provided that, if
an Event of Default shall have occurred and be continuing, the Collateral Agent
may select such Liquid Investments.

          (h) If immediately available cash on deposit in the Cash Collateral
Account is not sufficient to make any distribution or withdrawal to be made
pursuant hereto, the Collateral Agent will cause to be liquidated, as promptly
as practicable, such investments held in or credited to the Cash Collateral
Account as shall be required to obtain sufficient cash to make such distribution
or withdrawal and, notwithstanding any other provision hereof, such distribution
or withdrawal shall not be made until such liquidation has taken place.

          . (a) If an Event of Default shall have occurred and be continuing,
the Collateral Agent may exercise (or cause its sub-agents to exercise) any or
all of the remedies available to it (or to such sub-agents) under the Security
Documents.

          (b) Without limiting the generality of the foregoing, if an Event of
Default shall have occurred and be continuing, the Collateral Agent may exercise
on behalf of the Secured Parties all the rights of a secured party under the UCC
(whether or not in effect in the jurisdiction where such rights are exercised)
with respect to any Collateral and, in addition, the Collateral Agent may,
without being required to give any notice, except as herein provided or as may
be required by mandatory provisions of law, withdraw all cash held in the Cash
Collateral Account and apply such cash as provided in Section 7 and, if there
shall be no such cash or if such cash shall be insufficient to pay all the
Secured Obligations in full, sell, lease, license or otherwise dispose of the
Collateral or any part thereof. Notice of any such sale or other disposition
shall be given to the Lien Grantor as required by Section 9.

          (c) Without limiting the generality of the foregoing, during any Sweep
Period (as defined below), the Collateral Agent may (i) exercise all of the
remedies described in Section 5(f) and (ii) cause all amounts constituting
Collateral that are held in any lockbox, concentration or other account of the
Lien Grantor then subject to an effective Blocked Account Agreement (it being
understood that any Blocked Account Agreement with respect to an account that is
a "Lockbox Account" or "Concentration Account" (each as defined in the
Receivables Purchase Agreement) shall only become effective in accordance with
Section 5(b)(i)) to be transferred on a daily basis to the Cash Collateral
Account. As used herein, the term "Sweep Period" means each period that begins
upon the occurrence of (x) an Event of Default described in Section 7(a),
Section 7(i), Section 7(j) or Section 7(k) of the Credit Agreement or (y) an
Event of Default caused by the Borrower's failure to perform any covenant
contained in Section 6.13 or Section 6.14 of the Credit Agreement, and ends when
no such Event of Default is continuing; provided that, except in the case of a
Sweep Period that begins upon the occurrence of any Event of Default described
in Section 7(a), Section 7(i), Section 7(j) or Section 7(k) of the Credit
Agreement with respect to the Borrower (which Sweep Period shall commence
automatically upon the occurrence of such Event of Default), no Sweep Period
shall be deemed to have commenced unless and until the Collateral Agent shall
have so determined and shall have so notified the Borrower.

         . (a) If an Event of Default shall have occurred and be continuing, the
Collateral Agent may apply (i) any cash held in the Cash Collateral Account and
(ii) the proceeds of any sale or other disposition of all or any part of the
Collateral, in the following order of priorities:

          first, to pay the expenses of such sale or other disposition,
     including reasonable compensation to agents of and counsel for the
     Collateral Agent, and all expenses, liabilities and advances incurred or
     made by the Collateral Agent in connection with the Security Documents, and
     any other amounts then due and payable to the Collateral Agent pursuant to
     Section or to any Agent pursuant to the Credit Agreement;

          second, to pay the unpaid principal of the Secured Obligations (other
     than Second Secured Derivative Obligations) ratably (or provide for the
     payment thereof pursuant to Section 7(b)), until payment in full of the


     principal of all Secured Obligations (other than Second Secured Derivative
     Obligations) shall have been made (or so provided for);

          third, to pay ratably all interest (including Post-Petition Interest)
     on the Secured Obligations (other than Second Secured Derivative
     Obligations) and all commitment and other fees payable under the Related
     Documents, until payment in full of all such interest and fees shall have
     been made;

          fourth, to pay all other Secured Obligations (other than Second
     Secured Derivative Obligations) ratably (or provide for the payment thereof
     pursuant to Section 7(b)), until payment in full of all such other Secured
     Obligations (other than Second Secured Derivative Obligations) shall have
     been made (or so provided for);

          fifth, to pay ratably the unpaid principal of the Second Secured
     Derivative Obligations (or provide payment therefor pursuant to Section
     7(b)) until payment in full of the principal of all Second Secured
     Derivative Obligations shall have been made (or so provided for);

          sixth, to pay ratably all interest (including Post-Petition Interest)
     on the Second Secured Derivative Obligations, until payment in full of all
     such interest shall have been made; and

          finally, to pay to the Lien Grantor, or as a court of competent
     jurisdiction may direct, any surplus then remaining from the proceeds of
     the Collateral owned by it.

The Collateral Agent may make such distributions hereunder in cash or in kind
or, on a ratable basis, in any combination thereof.

          (b) If at any time any portion of any monies collected or received by
the Collateral Agent would, but for the provisions of this Section 7(b), be
payable pursuant to Section 7(a) in respect of an Unliquidated Secured
Obligation, the Collateral Agent shall not apply any monies to pay such
Unliquidated Secured Obligation but instead shall request the holder thereof, at
least 10 days before each proposed distribution hereunder, to notify the
Collateral Agent as to the maximum amount of such Unliquidated Secured
Obligation if then ascertainable (e.g., in the case of a letter of credit, the
maximum amount available for subsequent drawings thereunder). If the holder of
such Unliquidated Secured Obligation does not notify the Collateral Agent of the
maximum ascertainable amount thereof at least two Domestic Business Days before
such distribution, such Unliquidated Secured Obligation will not be entitled to
share in such distribution. If such holder does so notify the Collateral Agent
as to the maximum ascertainable amount thereof, the Collateral Agent will
allocate to such holder a portion of the monies to be distributed in such
distribution, calculated as if such Unliquidated Secured Obligation were
outstanding in such maximum ascertainable amount. However, the Collateral Agent
will not apply such portion of such monies to pay such Unliquidated Secured
Obligation, but instead will hold such monies or invest such monies in Liquid
Investments. All such monies and Liquid Investments and all proceeds thereof
will constitute Collateral hereunder, but will be subject to distribution in
accordance with this Section 7(b) rather than Section 7(a). The Collateral Agent
will hold all such monies and Liquid Investments and the net proceeds thereof in
trust until all or part of such Unliquidated Secured Obligation becomes a
Liquidated Secured Obligation, whereupon the Collateral Agent at the request of
the relevant Secured Party will apply the amount so held in trust to pay such
Liquidated Secured Obligation; provided that, if the other Secured Obligations
theretofore paid pursuant to the same clause of Section 7(a) (i.e., clause
second, fourth or fifth) were not paid in full, the Collateral Agent will apply
the amount so held in trust to pay the same percentage of such Liquidated
Secured Obligation as the percentage of such other Secured Obligations
theretofore paid pursuant to the same clause of Section 7(a). If (i) the holder
of such Unliquidated Secured Obligation shall advise the Collateral Agent that
no portion thereof remains in the category of an Unliquidated Secured Obligation
and (ii) the Collateral Agent still holds any amount held in trust pursuant to
this Section 7(b) in respect of such Unliquidated Secured Obligation (after
paying all amounts payable pursuant to the preceding sentence with respect to
any portions thereof that became Liquidated Secured Obligations), such remaining
amount will be applied by the Collateral Agent in the order of priorities set
forth in Section 7(a)

          (c) In making the payments and allocations required by this Section,
the Collateral Agent may rely upon information supplied to it pursuant to
Section 11(g). All distributions made by the Collateral Agent pursuant to this
Section shall be final (except in the event of manifest error) and the
Collateral Agent shall have no duty to inquire as to the application by any
Secured Party of any amount distributed to it.

          . (a) The Lien Grantor will forthwith upon demand pay to the
Collateral Agent:

               (i) the amount of any taxes that the Collateral Agent may have
          been required to pay by reason of the Transaction Liens or to free any
          Collateral from any other Lien thereon;

               (ii) the amount of any and all reasonable out-of-pocket expenses,
          including transfer taxes and reasonable fees and expenses of counsel
          and other experts, that the Collateral Agent may incur in connection


          with (x) the administration or enforcement of the Security Documents,
          including such expenses as are incurred to preserve the value of the
          Collateral or the validity, perfection, rank or value of any
          Transaction Lien, (y) the collection, sale or other disposition of any
          Collateral or (z) the exercise by the Collateral Agent of any of its
          rights or powers under the Security Documents;

               (iii) the amount of any fees that the Lien Grantor shall have
          agreed in writing to pay to the Collateral Agent and that shall have
          become due and payable in accordance with such written agreement; and

               (iv) the amount required to indemnify the Collateral Agent for,
          or hold it harmless and defend it against, any loss, liability or
          expense (including the reasonable fees and expenses of its counsel and
          any experts or sub-agents appointed by it hereunder) incurred or
          suffered by the Collateral Agent in connection with the Security
          Documents, except to the extent that such loss, liability or expense
          arises from the Collateral Agent's gross negligence or willful
          misconduct or a breach of any duty that the Collateral Agent has under
          this Agreement (after giving effect to Sections 10 and 11). Any such
          amount not paid to the Collateral Agent on demand will bear interest
          for each day thereafter until paid at a rate per annum equal to the
          sum of 2.00% plus the Alternate Base Rate for such day plus the
          Applicable Rate that would, in the absence of an Event of Default, be
          applicable to the Base Rate Loans for such day.

          (b) If any transfer tax, documentary stamp tax or other tax is payable
in connection with any transfer or other transaction provided for in the
Security Documents, the Lien Grantor will pay such tax and provide any required
tax stamps to the Collateral Agent or as otherwise required by law.

          . The Lien Grantor irrevocably appoints the Collateral Agent its true
and lawful attorney, with full power of substitution, in the name of the Lien
Grantor, any Secured Party or otherwise, for the sole use and benefit of the
Secured Parties, but at the Lien Grantor's expense, to the extent permitted by
law to exercise, at any time and from time to time while an Event of Default
shall have occurred and be continuing, all or any of the following powers with
respect to all or any of the Collateral (to the extent necessary to pay the
Secured Obligations in full):

          (a) to demand, sue for, collect, receive and give acquittance for any
     and all monies due or to become due upon or by virtue thereof,

          (b) to settle, compromise, compound, prosecute or defend any action or
     proceeding with respect thereto,

          (c) to sell, lease, license or otherwise dispose of the same or the
     proceeds or avails thereof, as fully and effectually as if the Collateral
     Agent were the absolute owner thereof, and

          (d) to extend the time of payment of any or all thereof and to make
     any allowance or other adjustment with reference thereto;

provided that, except in the case of Collateral that is perishable or threatens
to decline speedily in value or is of a type customarily sold on a recognized
market, the Collateral Agent will give the Lien Grantor at least ten days' prior
written notice of the time and place of any public sale thereof or the time
after which any private sale or other intended disposition thereof will be made.
Any such notice shall (i) contain the information specified in UCC Section
9-613, (ii) be Authenticated and (iii) be sent to the parties required to be
notified pursuant to UCC Section 9-611(c); provided that, if the Collateral
Agent fails to comply with this sentence in any respect, its liability for such
failure shall be limited to the liability (if any) imposed on it as a matter of
law under the UCC.

          . Beyond the exercise of reasonable care in the custody and
preservation thereof, the Collateral Agent will have no duty as to any
Collateral in its possession or control or in the possession or control of any
sub-agent or bailee or any income therefrom or as to the preservation of rights
against prior parties or any other rights pertaining thereto. The Collateral
Agent will be deemed to have exercised reasonable care in the custody and
preservation of the Collateral in its possession or control if such Collateral
is accorded treatment substantially equal to that which it accords its own
property, and will not be liable or responsible for any loss or damage to any
Collateral, or for any diminution in the value thereof, by reason of any act or
omission of any sub-agent or bailee selected by the Collateral Agent in good
faith or by reason of any act or omission by the Collateral Agent pursuant to
instructions from the Administrative Agent, except to the extent that such
liability arises from the Collateral Agent's gross negligence or willful
misconduct.

          . (a) Authority. The Collateral Agent is authorized to take such
actions and to exercise such powers as are delegated to the Collateral Agent by
the terms of the Security Documents, together with such actions and powers as
are reasonably incidental thereto.

          (b) Coordination with Secured Parties. To the extent requested to do
so by any Secured Party, the Collateral Agent will promptly notify such Secured
Party of each notice or other communication received by the Collateral Agent
hereunder and/or deliver a copy thereof to such Secured Party. As to any matters
not expressly


provided for herein (including (i) the timing and methods of realization upon
the Collateral and (ii) the exercise of any power that the Collateral Agent may,
but is not expressly required to, exercise under any Security Document), the
Collateral Agent shall act or refrain from acting in accordance with written
instructions from the Required Lenders or, in the absence of such instructions,
in accordance with its discretion (subject to the following provisions of this
Section).

          (c) Rights and Powers as a Secured Party. The Person serving as the
Collateral Agent shall, in its capacity as a Secured Party, have the same rights
and powers as any other Secured Party and may exercise the same as though it
were not the Collateral Agent. Such Person and its Affiliates may accept
deposits from, lend money to and generally engage in any kind of business with
the Borrower, any of its Subsidiaries or their respective Affiliates as if it
were not the Collateral Agent hereunder.

          (d) Limited Duties and Responsibilities. The Collateral Agent shall
not have any duties or obligations under the Security Documents except those
expressly set forth therein. Without limiting the generality of the foregoing,
(a) the Collateral Agent shall not be subject to any fiduciary or other implied
duties, regardless of whether an Event of Default has occurred and is
continuing, (b) the Collateral Agent shall not have any duty to take any
discretionary action or exercise any discretionary powers, except discretionary
rights and powers expressly contemplated by the Security Documents that the
Collateral Agent is required in writing to exercise by the Required Lenders, and
(c) except as expressly set forth in the Security Documents, the Collateral
Agent shall not have any duty to disclose, and shall not be liable for any
failure to disclose, any information relating to the Borrower or any of its
Subsidiaries that is communicated to or obtained by the bank serving as
Collateral Agent or any of its Affiliates in any capacity. The Collateral Agent
shall not be liable for any action taken or not taken by it with the consent or
at the request of the Required Lenders (or such other number or percentage of
the Lenders as shall be necessary under the circumstances as provided in Section
9.02 of the Credit Agreement) or in the absence of its own gross negligence or
willful misconduct. The Collateral Agent shall not be responsible for the
existence, genuineness or value of any Collateral or for the validity,
perfection, priority or enforceability of any Transaction Lien, whether impaired
by operation of law or by reason of any action or omission to act on its part
under the Security Documents. The Collateral Agent shall be deemed not to have
knowledge of any Event of Default unless and until written notice thereof is
given to the Collateral Agent by the Borrower or a Secured Party, and the
Collateral Agent shall not be responsible for or have any duty to ascertain or
inquire into (i) any statement, warranty or representation made in or in
connection with any Security Document, (ii) the contents of any certificate,
report or other document delivered thereunder or in connection therewith, (iii)
the performance or observance of any of the covenants, agreements or other terms
or conditions set forth in any Security Document, (iv) the validity,
enforceability, effectiveness or genuineness of any Security Document or any
other agreement, instrument or document, or (v) the satisfaction of any
condition set forth in any Security Document.

          (e) Authority to Rely on Certain Writings, Statements and Advice. The
Collateral Agent shall be entitled to rely on, and shall not incur any liability
for relying on, any notice, request, certificate, consent, statement,
instrument, document or other writing believed by it to be genuine and to have
been signed or sent by the proper Person. The Collateral Agent also may rely on
any statement made to it orally or by telephone and believed by it to be made by
the proper Person, and shall not incur any liability for relying thereon. The
Collateral Agent may consult with legal counsel (who may be counsel for the
Borrower or any of its Subsidiaries), independent accountants and other experts
selected by it, and shall not be liable for any action taken or not taken by it
in accordance with the advice of any such counsel, accountant or expert. The
Collateral Agent may rely conclusively on advice from the Administrative Agent
as to whether at any time (i) an Event of Default under the Credit Agreement has
occurred and is continuing, (ii) the maturity of the Loans has been accelerated
or (iii) any proposed action is permitted or required by the Credit Agreement.

          (f) Sub-Agents and Related Parties. The Collateral Agent may perform
any of its duties and exercise any of its rights and powers through one or more
sub-agents appointed by it. The Collateral Agent and any such sub-agent may
perform any of its duties and exercise any of its rights and powers through its
Related Parties. The exculpatory provisions of Section 10 and this Section shall
apply to any such sub-agent and to the Related Parties of the Collateral Agent
and any such sub-agent.

          (g) Information as to Secured Obligations and Actions by Secured
Parties. For all purposes of the Security Documents, including determining the
amounts of the Secured Obligations and whether a Secured Obligation is an
Unliquidated Secured Obligation or not, or whether any action has been taken
under any Secured Agreement, the Collateral Agent will be entitled to rely on
information from (i) the Administrative Agent for information as to the


Lenders, the Administrative Agent or the Collateral Agent, their Secured
Obligations and actions taken by them, (ii) any Secured Party for information as
to its Secured Obligations and actions taken by it, to the extent that the
Collateral Agent has not obtained such information from the foregoing sources,
and (iii) the Borrower, to the extent that the Collateral Agent has not obtained
information from the foregoing sources.

          (h) Within two Business Days after it receives or sends any notice
referred to in this subsection, the Collateral Agent shall send to the
Administrative Agent and each Secured Party requesting notice thereof, copies of
any notice given by the Collateral Agent to the Lien Grantor, or received by it
from the Lien Grantor, pursuant to Section 6, 7, 9, 11(j) or 12; provided that
such Secured Party has, at least five Domestic Business Days prior thereto,
delivered to the Collateral Agent a written notice (i) stating that it holds one
or more Secured Obligations and wishes to receive copies of such notices and
(ii) setting forth its address, facsimile number and e-mail address to which
copies of such notices should be sent.

          (i) The Collateral Agent may refuse to act on any notice, consent,
direction or instruction from the Administrative Agent or any Secured Parties or
any agent, trustee or similar representative thereof that, in the Collateral
Agent's opinion, (i) is contrary to law or the provisions of any Security
Document, (ii) may expose the Collateral Agent to liability (unless the
Collateral Agent shall have been indemnified, to its reasonable satisfaction,
for such liability by the Secured Parties that gave, or instructed the Agent to
give, such notice, consent, direction or instruction) or (iii) is unduly
prejudicial to Secured Parties not joining in such notice, consent, direction or
instruction.

          (j) Resignation; Successor Collateral Agent. Subject to the
appointment and acceptance of a successor Collateral Agent as provided in this
subsection, the Collateral Agent may resign at any time by notifying the Secured
Parties and the Borrower. Upon any such resignation, the Required Lenders shall
have the right, in consultation with the Lien Grantor, to appoint a successor
Collateral Agent. If no successor shall have been so appointed by the Required
Lenders and shall have accepted such appointment within 30 days after the
retiring Collateral Agent gives notice of its resignation, then the retiring
Collateral Agent may, on behalf of the Secured Parties, appoint a successor
Collateral Agent which shall be a bank with an office in the United States, or
an Affiliate of any such bank. Upon acceptance of its appointment as Collateral
Agent hereunder by a successor, such successor shall succeed to and become
vested with all the rights, powers, privileges and duties of the retiring
Collateral Agent hereunder, and the retiring Collateral Agent shall be
discharged from its duties and obligations hereunder. The fees payable by the
Lien Grantor to a successor Collateral Agent shall be the same as those payable
to its predecessor unless otherwise agreed by the Lien Grantor and such
successor. After the Collateral Agent's resignation hereunder, the provisions of
this Section and Section shall continue in effect for the benefit of such
retiring Collateral Agent, its sub-agents and their respective Related Parties
in respect of any actions taken or omitted to be taken by any of them while the
retiring Collateral Agent was acting as Collateral Agent.

          (a) The Transaction Liens shall terminate when all the Release
Conditions are satisfied.

          (b) The Transaction Liens (x) with respect to any Pledged Receivables
shall terminate when such Receivables have become Transferred Receivables and
(y) with respect to any other Collateral shall terminate upon the sale of such
Collateral to a Person other than the Lien Grantor in a transaction not
prohibited by the Credit Agreement. In each case, such termination shall not
require the consent of any Secured Party, and the Collateral Agent and any third
party shall be fully protected in relying on a certificate of the Lien Grantor
as to whether any Pledged Receivables qualify as Transferred Receivables
(including without limitation whether the transfer thereof is permitted under

          (c) In the case of any Pledged Receivables, the Transaction Liens with
respect to the Related Transferred Rights shall terminate when such Pledged
Receivables become Transferred Receivables. Such termination shall not require
the consent of any Secured Party. If the Borrower delivers a certificate

portion of the Collateral with the prior written consent of all the Lenders. For

substantial portion of the Collateral.

Collateral, the Collateral Agent will, at the expense of the Lien Grantor,
execute and deliver to the Lien Grantor such documents as the Lien Grantor shall
reasonably request to evidence the termination of such Transaction Lien or the
release of such Collateral, as the case may be.
