                                   The Credits

     Section 1.1. Commitments. (a) Subject to the terms and conditions set forth
herein, each Lender agrees to make Revolving Loans to the Borrower from time to
time during the Revolving Availability Period in an aggregate principal amount
that will not at any time result in (A) such Lender's Exposure exceeding its
Commitment or (B) the Total Outstanding Amount exceeding the Maximum Facility
Availability then in effect. Within the foregoing limits and subject to the
terms and conditions set forth herein, the Borrower may borrow, prepay and
reborrow Revolving Loans.

     (b) The Commitments of the Lenders are several, i.e., the failure of any
Lender to make any Loan required to be made by it shall not relieve any other
Lender of its obligations hereunder, and no Lender shall be responsible for any
other Lender's failure to make Loans as and when required hereunder.

                                       34
<PAGE>

     Section 1.2. Revolving Loans. (a) Each Revolving Loan shall be made as part
of a Borrowing consisting of Loans of the same Interest Type made by the Lenders
ratably in accordance with their respective Commitments, as the Borrower may
request (subject to Section 2.14) in accordance herewith. Each Lender at its
option may make any Eurodollar Loan by causing any domestic or foreign branch or
Affiliate of such Lender to make such Loan. Any exercise of such option shall
not affect the Borrower's obligation to repay such Loan as provided herein.

     (b) At the beginning of each Interest Period for any Eurodollar Borrowing,
the aggregate amount of such Borrowing shall be an integral multiple of
$1,000,000 and not less than $5,000,000. When each Base Rate Borrowing is made,
the aggregate amount of such Borrowing shall be an integral multiple of
$1,000,000 and not less than $5,000,000; provided that a Base Rate Borrowing may
be in an aggregate amount that (i) is equal to the entire unused balance of the
Commitments or (ii) is required to finance the reimbursement of an LC
Disbursement as contemplated by Section 2.05(e). Borrowings of more than one
Interest Type may be outstanding at the same time; provided that there shall not
at any time be more than a total of seven Eurodollar Borrowings outstanding.

     (c) Notwithstanding any other provision hereof, the Borrower will not be
entitled to request, or to elect to convert or continue, any Eurodollar
Borrowing if the Interest Period requested with respect thereto would end after
the Maturity Date.

     Section 1.3. Requests to Borrow Revolving Loans. To request a Revolving
Borrowing, the Borrower shall notify the Administrative Agent of such request by
telephone (a) in the case of a Eurodollar Borrowing, not later than 11:00 a.m.,
New York City time, three Business Days before the date of the proposed
Borrowing or (b) in the case of a Base Rate Borrowing, not later than 12:00
noon, New York City time, on the date of the proposed Borrowing. Each such
telephonic Borrowing Request shall be irrevocable and shall be confirmed
promptly by hand delivery or telecopy to the Administrative Agent of a written
Borrowing Request in a form approved by the Administrative Agent and signed by
the Borrower. Each such telephonic and written Borrowing Request shall specify
the following information in compliance with Section 2.02:

          (i) the aggregate amount of such Borrowing;

          (ii) the date of such Borrowing, which shall be a Business Day;

          (iii) whether such Borrowing is to be a Base Rate Borrowing or a
     Eurodollar Borrowing;

          (iv) in the case of a Eurodollar Borrowing, the initial Interest

                                       35
<PAGE>

     Period to be applicable thereto, which shall be a period contemplated by
     the definition of "Interest Period"; and

          (v) the location and number of the Borrower's account to which funds
     are to be disbursed, which shall comply with the requirements of Section
     2.06.

If no election as to the Interest Type of a Borrowing is specified, the
requested Borrowing will be a Base Rate Borrowing. If no Interest Period with
respect to a requested Eurodollar Borrowing is specified, the Borrower will be
deemed to have selected an Interest Period of one month's duration. Promptly
after it receives a Borrowing Request in accordance with this Section, the
Administrative Agent shall advise each Lender as to the details of such
Borrowing Request and the amount of such Lender's Loan to be made pursuant
thereto.

     Section 1.4. Swingline Loans. (a) Subject to the terms and conditions set
forth herein, the Swingline Lender agrees to make Swingline Loans to the
Borrower from time to time during the Revolving Availability Period, in each
case in an amount that (i) is an integral multiple of $100,000 and not less than
$250,000, (ii) will not result in the aggregate outstanding principal amount of
all Swingline Loans exceeding $25,000,000 and (iii) will not result in the Total
Outstanding Amount exceeding the Maximum Facility Availability then in effect;
provided that the Swingline Lender will not be required to make a Swingline Loan
to refinance an outstanding Swingline Loan. Within the foregoing limits and
subject to the terms and conditions set forth herein, the Borrower may borrow,
prepay and reborrow Swingline Loans.

     (b) To request a Swingline Loan, the Borrower shall notify the
Administrative Agent of such request by telephone (confirmed by telecopy or
e-mail transmission), not later than 3:00 p.m., New York City time, on the
proposed date of borrowing. Each such notice shall be irrevocable and shall
specify the requested date (which shall be a Business Day) and amount of the
requested Swingline Loan. The Administrative Agent shall promptly advise the
Swingline Lender of any such notice received from the Borrower. The Swingline
Lender shall make each Swingline Loan available to the Borrower by means of a
credit to the Borrower's general deposit account with the Swingline Lender (or,
if such Swingline Loan is made to finance the reimbursement of an LC
Disbursement as provided in Section 2.05(e), by remittance to the LC Issuing
Bank) by 5:00 p.m., New York City time, on the requested date of such Swingline
Loan. Each Swingline Loan shall bear interest at the rate specified in Section
2.13(c).

     (c) The Borrower unconditionally promises to pay to the Swingline Lender
the then unpaid principal amount of each Swingline Loan on the earlier of

                                       36
<PAGE>

the Maturity Date and the first day after such Swingline Loan is made that is
the 15th or last day of a calendar month and is one Business Day after such
Swingline Loan is made; provided that on each day that a Borrowing of Revolving
Loans is made, the Borrower shall repay all Swingline Loans that were
outstanding when such Borrowing was requested.

     (d) The Borrower will have the right at any time to prepay any Swingline
Loan in full or in part in an amount that is an integral multiple of $100,000
and not less than $250,000. The Borrower shall notify the Swingline Lender and
the Administrative Agent, by telephone (confirmed by telecopy or e-mail
transmission), of the date and amount of any such prepayment not later than
12:00 noon on the date of prepayment. Each such prepayment shall be made
directly to the Swingline Lender and shall be accompanied by accrued interest on
the amount prepaid.

     (e) The Swingline Lender may, by written notice given to the Administrative
Agent not later than 3:00 p.m., New York City time, on any Business Day, require
the Lenders to acquire participations on such Business Day in all or a portion
of the Swingline Loans then outstanding. Such notice shall specify the aggregate
amount of Swingline Loans in which Lenders will participate. Promptly after it
receives such notice, the Administrative Agent shall notify each Lender as to
the details thereof and such Lender's Percentage of such aggregate amount of
Swingline Loans. Each Lender agrees, upon receipt of such notification, to pay
to the Administrative Agent, for the account of the Swingline Lender, such
Lender's Percentage of such aggregate amount of Swingline Loans. Each Lender's
obligation to acquire participations in Swingline Loans pursuant to this
subsection is absolute and unconditional and shall not be affected by any
circumstance whatsoever, including the occurrence and continuance of a Default
or any reduction or termination of the Commitments, and each payment by a Lender
to acquire such participations shall be made without any offset, abatement,
withholding or reduction whatsoever. Each Lender shall comply with its
obligation under this subsection by wire transfer of immediately available
funds, in the same manner as provided in Section 2.06 with respect to Loans made
by such Lender (and Section 2.06(b) shall apply, mutatis mutandis, to the
payment obligations of the Lenders under this subsection), and the
Administrative Agent shall promptly pay to the Swingline Lender the amounts so
received by it from the Lenders. The Administrative Agent shall notify the
Borrower of any participations in Swingline Loans acquired pursuant to this
subsection, and thereafter payments in respect of such Swingline Loans shall be
made to the Administrative Agent and not to the Swingline Lender. Any amounts
received by the Swingline Lender from the Borrower (or any other party on behalf
of the Borrower) in respect of a Swingline Loan after the Swingline Lender
receives the proceeds of a sale of participations therein shall be promptly
remitted to the Administrative Agent, which shall promptly remit any such
amounts received by it to the Lenders that shall have made payments pursuant to
this subsection and to the Swingline Lender, as their interests may appear. The
purchase of

                                       37
<PAGE>

participations in Swingline Loans pursuant to this subsection will not relieve
the Borrower of any default in the payment thereof.

     Section 1.5. Letters of Credit. (a) General. Subject to the terms and
conditions set forth herein, the Borrower may request the issuance of Letters of
Credit for its own account, in a form reasonably acceptable to the
Administrative Agent and the LC Issuing Bank, from time to time during the
Revolving Availability Period. If the terms and conditions of any form of letter
of credit application or other agreement submitted by the Borrower to, or
entered into by the Borrower with, the LC Issuing Bank relating to any Letter of
Credit are not consistent with the terms and conditions of this Agreement, the
terms and conditions of this Agreement shall control.

     (b) Notice of Issuance, Amendment, Renewal or Extension; Certain
Conditions. To request the issuance of a Letter of Credit (or the amendment,
renewal or extension of an outstanding Letter of Credit), the Borrower shall
hand deliver or telecopy (or transmit by electronic communication, if
arrangements for doing so have been approved by the LC Issuing Bank) to the LC
Issuing Bank and the Administrative Agent (reasonably in advance of the
requested date of issuance, amendment, renewal or extension) a notice requesting
the issuance of a Letter of Credit, or identifying the Letter of Credit to be
amended, renewed or extended, and specifying the requested date of issuance,
amendment, renewal or extension (which shall be a Business Day), the date on
which such Letter of Credit is to expire (which shall comply with Section
2.05(c)), the amount of such Letter of Credit, the name and address of the
beneficiary thereof and such other information as shall be necessary to prepare,
amend, renew or extend such Letter of Credit. If requested by the LC Issuing
Bank, the Borrower also shall submit a letter of credit application on the LC
Issuing Bank's standard form (with such changes as are agreed by such LC Issuing
Bank and the Borrower) in connection with any request for a Letter of Credit. A
Letter of Credit shall be issued, amended, renewed or extended only if (and upon
issuance, amendment, renewal or extension of each Letter of Credit the Borrower
shall be deemed to represent and warrant that), after giving effect to such
issuance, amendment, renewal or extension, (i) the LC Exposure will not exceed
$75,000,000 and (ii) the Total Outstanding Amount will not exceed the Maximum
Facility Availability then in effect.

     (c) Expiration Date. Each Letter of Credit shall expire at or before the
close of business on the earlier of (i) the date that is eighteen months after
such Letter of Credit is issued (or, in the case of any renewal or extension
thereof, eighteen months after such renewal or extension) and (ii) the date that
is five Business Days before the Maturity Date.

     (d) Participations. Effective upon the issuance of a Letter of Credit (or
an amendment to a Letter of Credit increasing the amount thereof) and without

                                       38
<PAGE>

any further action on the part of the LC Issuing Bank or the Lenders, the LC
Issuing Bank grants to each Lender, and each Lender acquires from the LC Issuing
Bank, a participation in such Letter of Credit equal to such Lender's Percentage
of the aggregate amount available to be drawn thereunder. Pursuant to such
participations, each Lender agrees to pay to the Administrative Agent, for the
account of the LC Issuing Bank, such Lender's Percentage of (i) each LC
Disbursement made by the LC Issuing Bank and not reimbursed by the Borrower on
the date due as provided in Section 2.05(e) and (ii) any reimbursement payment
required to be refunded to the Borrower for any reason. Each Lender's obligation
to acquire participations and make payments pursuant to this subsection is
absolute and unconditional and shall not be affected by any circumstance
whatsoever, including any amendment, renewal or extension of any Letter of
Credit or the occurrence and continuance of a Default or any reduction or
termination of the Commitments, and each such payment shall be made without any
offset, abatement, withholding or reduction whatsoever.

     (e) Reimbursement. If the LC Issuing Bank makes any LC Disbursement under a
Letter of Credit, the Borrower shall reimburse such LC Disbursement by paying an
amount equal to such LC Disbursement to the Administrative Agent not later than
12:00 noon, New York City time, on the day that such LC Disbursement is made, if
the Borrower receives notice of such LC Disbursement before 10:00 a.m., New York
City time, on such day, or, if such notice has not been received by the Borrower
before such time on such day, then not later than 12:00 noon, New York City
time, on (i) the Business Day that the Borrower receives such notice, if such
notice is received before 10:00 a.m., New York City time, on the day of receipt,
or (ii) the next Business Day, if such notice is not received before such time
on the day of receipt; provided that, if such LC Disbursement is at least
$250,000, the Borrower may, subject to the conditions to borrowing set forth
herein, request in accordance with Section 2.03 or 2.04 that such payment be
made with the proceeds of a Base Rate Revolving Loan or a Swingline Loan in an
equivalent amount and, to the extent so financed, the Borrower's obligation to
make such payment shall be discharged and replaced by the resulting Base Rate
Revolving Loan or Swingline Loan. If the Borrower fails to make such payment
when due, the Administrative Agent shall notify each Lender of the applicable LC
Disbursement, the payment then due from the Borrower in respect thereof and such
Lender's Percentage thereof. Promptly after it receives such notice, each Lender
shall pay to the Administrative Agent its Percentage of the payment then due
from the Borrower, in the same manner as is provided in Section 2.06 with
respect to Loans made by such Lender (and Section 2.06(b) shall apply, mutatis
mutandis, to such payment obligations of the Lenders), and the Administrative
Agent shall promptly pay to the LC Issuing Bank the amounts so received by it
from the Lenders. If a Lender makes a payment pursuant to this subsection to
reimburse the LC Issuing Bank for any LC Disbursement (other than by funding
Base Rate Revolving Loans as contemplated above), (i) such payment will not
constitute a Loan and will not relieve the Borrower of its obligation to
reimburse such LC Disbursement and (ii) such

                                       39
<PAGE>

Lender will be subrogated to its pro rata share of the LC Issuing Bank's claim
against the Borrower for such reimbursement. Promptly after the Administrative
Agent receives any payment from the Borrower pursuant to this subsection, the
Administrative Agent will distribute such payment to the LC Issuing Bank or, if
Lenders have made payments pursuant to this subsection to reimburse the LC
Issuing Bank, then to such Lenders and the LC Issuing Bank as their interests
may appear.

     (f) Obligations Absolute. The Borrower's obligation to reimburse LC
Disbursements as provided in Section 2.05(e) shall be absolute, unconditional
and irrevocable, and shall be performed strictly in accordance with the terms of
this Agreement under any and all circumstances whatsoever and irrespective of
(i) any lack of validity or enforceability of any Letter of Credit or this
Agreement, or any term or provision therein, (ii) any draft or other document
presented under a Letter of Credit proving to be forged, fraudulent or invalid
in any respect or any statement therein being untrue or inaccurate in any
respect, (iii) payment by the LC Issuing Bank under a Letter of Credit against
presentation of a draft or other document that does not comply with the terms of
such Letter of Credit, or (iv) any other event or circumstance whatsoever,
whether or not similar to any of the foregoing, that might, but for the
provisions of this Section, constitute a legal or equitable discharge of, or
provide a right of setoff against, the Borrower's obligations hereunder. None of
the Administrative Agent, the Lenders, the LC Issuing Bank and their respective
Related Parties shall have any liability or responsibility by reason of or in
connection with the issuance or transfer of any Letter of Credit or any payment
or failure to make any payment thereunder (irrespective of any of the
circumstances referred to in the preceding sentence), or any error, omission,
interruption, loss or delay in transmission or delivery of any draft, notice or
other communication under or relating to any Letter of Credit (including any
document required to make a drawing thereunder), any error in interpretation of
technical terms or any consequence arising from causes beyond the control of the
LC Issuing Bank; provided that the foregoing shall not excuse the LC Issuing
Bank from liability to the Borrower to the extent of any direct damages (as
opposed to consequential damages, claims in respect of which are waived by the
Borrower to the extent permitted by applicable law) suffered by the Borrower
that are caused by the LC Issuing Bank's failure to exercise care when
determining whether drafts and other documents presented under a Letter of
Credit comply with the terms thereof. In the absence of gross negligence or
wilful misconduct on the part of the LC Issuing Bank (as finally determined by a
court of competent jurisdiction), the LC Issuing Bank shall be deemed to have
exercised care in each such determination. Without limiting the generality of
the foregoing, the parties agree that, with respect to documents presented which
appear on their face to be in substantial compliance with the terms of a Letter
of Credit, the LC Issuing Bank may, in its sole discretion, either (A) accept
and make payment upon such documents without responsibility for further
investigation, regardless of any notice or information to the contrary, or (B)
refuse to accept and make payment upon such documents if such documents do not

                                       40
<PAGE>

strictly comply with the terms of such Letter of Credit.

     (g) Disbursement Procedures. The LC Issuing Bank shall, promptly after its
receipt thereof, examine all documents purporting to represent a demand for
payment under a Letter of Credit. The LC Issuing Bank shall promptly notify the
Administrative Agent and the Borrower by telephone (confirmed by telecopy) of
such demand for payment and whether the LC Issuing Bank has made or will make an
LC Disbursement pursuant thereto; provided that any failure to give or delay in
giving such notice will not relieve the Borrower of its obligation to reimburse
the LC Issuing Bank and the Lenders with respect to any such LC Disbursement.

     (h) Interim Interest. Unless the Borrower reimburses an LC Disbursement in
full on the day it is made, the unpaid amount thereof shall bear interest, for
each day from and including the day on which such LC Disbursement is made to but
excluding the day on which the Borrower reimburses such LC Disbursement, at the
rate per annum then applicable to Base Rate Revolving Loans; provided that, if
the Borrower fails to reimburse such LC Disbursement when due pursuant to
Section 2.05(e), then Sections 2.13(d) and 2.13(e) shall apply. Interest accrued
pursuant to this subsection shall be for the account of the LC Issuing Bank,
except that a pro rata share of interest accrued on and after the day that any
Lender reimburses the LC Issuing Bank for a portion of such LC Disbursement
pursuant to Section 2.05(e) shall be for the account of such Lender.

     (i) Replacement of LC Issuing Bank. The LC Issuing Bank may be replaced at
any time by written agreement among the Borrower, the Administrative Agent, the
replaced LC Issuing Bank and the successor LC Issuing Bank. The Administrative
Agent shall notify the Lenders of any such replacement. At the time any such
replacement becomes effective, the Borrower shall pay all unpaid fees accrued
for the account of the replaced LC Issuing Bank pursuant to Section 2.12(b). On
and after the effective date of any such replacement, (i) the successor LC
Issuing Bank will have all the rights and obligations of the LC Issuing Bank
under this Agreement with respect to Letters of Credit to be issued thereafter
and (ii) references herein to the term "LC Issuing Bank" will be deemed to refer
to such successor or to any previous LC Issuing Bank, or to such successor and
all previous LC Issuing Banks, as the context shall require. After an LC Issuing
Bank is replaced, it will remain a party hereto and will continue to have all
the rights and obligations of an LC Issuing Bank under this Agreement with
respect to Letters of Credit issued by it before such replacement, but will not
be required to issue additional Letters of Credit.

     (j) Cash Collateralization. If an Event of Default shall occur and be
continuing, on the Business Day that the Borrower receives notice from the
Administrative Agent or the Required Lenders (or, if the maturity of the Loans
has been accelerated, Lenders with LC Exposures representing more than 50% of
the total LC Exposure) demanding the deposit of cash collateral pursuant to this

                                       41
<PAGE>

subsection, the Borrower shall deposit in its Cash Collateral Account an amount
in cash equal to 102% of the total LC Exposure as of such date plus any accrued
and unpaid interest thereon; provided that the obligation to deposit such cash
collateral will become effective immediately, and such deposit will become
immediately due and payable, without demand or other notice of any kind, upon
the occurrence of any Event of Default with respect to the Borrower described in
clause (i) or (j) of Article 7. Any amount so deposited (including any earnings
thereon) will be withdrawn from the Borrower's Cash Collateral Account by the
Administrative Agent and applied to pay LC Reimbursement Obligations as they
become due; provided that (i) if at any time all Events of Default have been
cured or waived, such amount, to the extent not theretofore so applied, (and
excluding amounts required to be deposited in the Cash Collateral Account
pursuant to Section 2.10(b) or Section 5.12(b)) will be returned to the Borrower
upon its request and (ii) if at any time the maturity of the Loans has been
accelerated, such amount (to the extent not theretofore so applied or returned)
will be applied to pay the Secured Obligations as provided in Section 7 of the
Security Agreement.

     Section 1.6. Funding of Revolving Loans. (a) Each Lender making a Revolving
Loan hereunder shall wire the principal amount thereof in immediately available
funds, by 1:00 p.m., New York City time, on the proposed date of such Loan, to
the account of the Administrative Agent most recently designated by it for such
purpose by notice to the Lenders. The Administrative Agent shall make such funds
available to the Borrower by promptly crediting the amounts so received, in like
funds, to an account of the Borrower maintained with the Administrative Agent in
New York City and designated by the Borrower in the applicable Borrowing
Request; provided that Base Rate Revolving Loans made to finance the
reimbursement of an LC Disbursement as provided in Section 2.05(e) will be
remitted by the Administrative Agent to the LC Issuing Bank.

     (b) Unless the Administrative Agent receives notice from a Lender before
the proposed date of any Borrowing that such Lender will not make its share of
such Borrowing available to the Administrative Agent, the Administrative Agent
may assume that such Lender has made such share available on such date in
accordance with Section 2.06(a) and may, in reliance on such assumption, make a
corresponding amount available to the Borrower. In such event, if a Lender has
not in fact made its share of such Borrowing available to the Administrative
Agent, such Lender and the Borrower severally agree to pay to the Administrative
Agent forthwith on demand such corresponding amount with interest thereon, for
each day from and including the day such amount is made available to the
Borrower to but excluding the date of payment to the Administrative Agent, at
(i) in the case of such Lender, the greater of the Federal Funds Effective Rate
and a rate reasonably determined by the Administrative Agent in accordance with
banking industry rules on interbank compensation or (ii) in the case of the
Borrower, the interest rate applicable to Base Rate Loans. If

                                       42
<PAGE>

such Lender pays such amount to the Administrative Agent, such amount shall
constitute such Lender's Loan included in such Borrowing.

     Section 1.7. Interest Elections. (a) Each Borrowing of Revolving Loans
initially shall be of the Interest Type specified in the applicable Borrowing
Request and, in the case of a Eurodollar Borrowing, shall have an initial
Interest Period as specified in such Borrowing Request. Thereafter, the Borrower
may elect to convert such Borrowing to a different Interest Type or, in the case
of a Eurodollar Borrowing, to continue such Borrowing for one or more additional
Interest Periods, all as provided in this Section. The Borrower may elect
different options with respect to different portions of the affected Borrowing,
in which case each such portion shall be allocated ratably among the Lenders
holding the Loans comprising such Borrowing, and the Loans comprising each such
portion shall be considered a separate Borrowing.

     (b) To make an election pursuant to this Section, the Borrower shall notify
the Administrative Agent thereof by telephone by the time that a Borrowing
Request would be required under Section 2.03 if the Borrower were requesting
that a Borrowing of the Interest Type resulting from such election be made on
the effective date of such election. Each such telephonic Interest Election
shall be irrevocable and shall be confirmed promptly by hand delivery, telecopy
or e-mail transmission to the Administrative Agent of a written Interest
Election in a form approved by the Administrative Agent and signed by the
Borrower.

     (c) Each telephonic and written Interest Election shall specify the
following information in compliance with Section 2.02 and subsection (e) of this
Section:

          (i) the Borrowing to which such Interest Election applies and, if
     different options are being elected with respect to different portions
     thereof, the portions thereof to be allocated to each resulting Borrowing
     (in which case the information to be specified pursuant to clauses (iii)
     and (iv) below shall be specified for each resulting Borrowing);

          (ii) the effective date of the election made pursuant to such Interest
     Election, which shall be a Business Day;

          (iii) whether the resulting Borrowing is to be a Base Rate Borrowing
     or a Eurodollar Borrowing; and

          (iv) if the resulting Borrowing is to be a Eurodollar Borrowing, the
     Interest Period to be applicable thereto after giving effect to such
     election, which shall be a period contemplated by the definition of
     "Interest Period".

                                       43
<PAGE>

If an Interest Election requests a Eurodollar Borrowing but does not specify an
Interest Period, the Borrower will be deemed to have selected an Interest Period
of one month's duration.

     (d) Promptly after it receives an Interest Election, the Administrative
Agent shall advise each Lender as to the details thereof and such Lender's
portion of each resulting Borrowing.

     (e) If the Borrower fails to deliver a timely Interest Election with
respect to a Eurodollar Borrowing before the end of an Interest Period
applicable thereto, such Borrowing (unless repaid) will be converted to a Base
Rate Borrowing at the end of such Interest Period. Notwithstanding any contrary
provision hereof, if an Event of Default has occurred and is continuing and the
Administrative Agent, at the request of the Required Lenders, so notifies the
Borrower, then, so long as an Event of Default is continuing, (i) no outstanding
Borrowing may be converted to or continued as a Eurodollar Borrowing and (ii)
each Eurodollar Borrowing (unless repaid) will be converted to a Base Rate
Borrowing at the end of the Interest Period applicable thereto on the date of
such notice.

     Section 1.8. Termination or Reduction of Commitments. (a) Unless previously
terminated, the Commitments will terminate on the Maturity Date.

     (b) The Borrower may at any time terminate, or from time to time reduce,
the Commitments; provided that (i) the amount of each reduction of the
Commitments shall be an integral multiple of $1,000,000 and not less than
$5,000,000 and (ii) the Borrower shall not terminate or reduce the Commitments
if, after giving effect thereto and to any concurrent prepayment of Revolving
Loans pursuant to Section 2.10, the total Exposures would exceed the total
Commitments.

     (c) The Borrower shall notify the Administrative Agent of any election to
terminate or reduce the Commitments under Section 2.08(b), at least three
Business Days before the effective date of such termination or reduction,
specifying such election and the effective date thereof. Promptly after it
receives any such notice, the Administrative Agent shall advise the Lenders of
the contents thereof. Each notice delivered by the Borrower pursuant to this
Section will be irrevocable; provided that any such notice terminating the
Commitments may state that it is conditioned on the effectiveness of other
credit facilities, in which case such notice may be revoked by the Borrower (by
notice to the Administrative Agent on or before the specified effective date) if
such condition is not satisfied. Any termination or reduction of the Commitments
will be permanent and will be made ratably among the Lenders in accordance with
their respective Commitments.

                                       44

     Section 1.9. Payment at Maturity; Evidence of Debt. (a) The Borrower
unconditionally promises to pay to the Administrative Agent on the Maturity
Date, for the account of each Lender, the then unpaid principal amount of such
Lender's Revolving Loans.

     (b) Each Lender shall maintain in accordance with its usual practice an
account or accounts evidencing the indebtedness of the Borrower to such Lender
resulting from each Loan made by such Lender, including the amounts of principal
and interest payable and paid to such Lender from time to time.

     (c) The Administrative Agent shall maintain accounts in which it shall
record (i) the amount of each Loan made hereunder, the Interest Type thereof and
each Interest Period (if any) applicable thereto, (ii) the amount of any
principal or interest due and payable or to become due and payable from the
Borrower to each Lender hereunder and (iii) the amount of any sum received by
the Administrative Agent hereunder for the account of the Lenders and each
Lender's share thereof.

     (d) The entries made in the accounts maintained pursuant to subsections (b)
and (c) of this Section shall be prima facie evidence of the existence and
amounts of the obligations recorded therein; provided that any failure by any
Lender or the Administrative Agent to maintain such accounts or any error
therein shall not affect the Borrower's obligation to repay the Loans in
accordance with the terms of this Agreement.

     (e) Any Lender may request that Loans made by it be evidenced by a
promissory note. In such event, the Borrower shall prepare, execute and deliver
to such Lender a promissory note payable to the order of such Lender (or, if
requested by such Lender, to such Lender and its registered assigns) and in a
form approved by the Administrative Agent. Thereafter, the Loans evidenced by
such promissory note and interest thereon shall at all times (including after
assignment pursuant to Section 9.04) be represented by one or more promissory
notes in such form payable to the order of the payee named therein (or, if such
promissory note is a registered note, to such payee and its registered assigns).

     Section 1.10. Optional and Mandatory Prepayments. (a) Optional Prepayments.
The Borrower will have the right at any time to prepay any Borrowing in whole or
in part, subject to the provisions of this Section.

     (b) Mandatory Prepayments. If at any date the Total Outstanding Amount
exceeds the Maximum Facility Availability calculated as of such date, then not
later than the next succeeding Business Day, the Borrower shall be required to
prepay the Loans (or, if no Loans are outstanding, deposit cash in the Cash
Collateral Account to cash collateralize Letter of Credit liabilities) in an
amount equal to such excess until the Total Outstanding Amount, net of the
amount of cash collateral deposited in the Cash Collateral Account, does not

                                       45
<PAGE>

exceed the Maximum Facility Availability.

     (c) Allocation of Prepayments. Before any optional or mandatory prepayment
of Borrowings hereunder, the Borrower shall select the Borrowing or Borrowings
to be prepaid and shall specify such selection in the notice of such prepayment
pursuant to Section 2.10(f).

     (d) Partial Prepayments. Each partial prepayment of a Borrowing shall be in
an amount that would be permitted under Section 2.02(b) for a Borrowing of the
same Interest Type, except as needed to apply fully the required amount of a
mandatory prepayment. Each partial prepayment of a Borrowing shall be applied
ratably to the Loans included in such Borrowing.

     (e) Accrued Interest. Each prepayment of a Borrowing shall be accompanied
by accrued interest to the extent required by Section 2.11 or Section 2.13.

     (f) Notice of Prepayments. The Borrower shall notify the Administrative
Agent by telephone (confirmed by telecopy or e-mail transmission) of any
prepayment of any Borrowing hereunder (i) in the case of a Eurodollar Borrowing,
not later than 12:00 noon, New York City time, three Business Days before the
date of prepayment and (ii) in the case of a Base Rate Borrowing, not later than
12:00 noon, New York City time, on the date of prepayment. Each such notice
shall be irrevocable and shall specify the prepayment date, the principal amount
of each Borrowing or portion thereof to be prepaid and, in the case of a
mandatory prepayment, a reasonably detailed calculation of the amount of such
prepayment; provided that, if a notice of optional prepayment is given in
connection with a conditional notice of termination of the Commitments as
contemplated by Section 2.08(c), then such notice of prepayment may be revoked
if such notice of termination is revoked in accordance with Section 2.08(c).
Promptly after it receives any such notice, the Administrative Agent shall
advise the Lenders of the contents thereof.

     Section 1.11. Change in Control. (a) If a Change in Control of the Borrower
shall occur, the Borrower will, within one Business Day after the occurrence
thereof, give the Administrative Agent notice thereof, and the Administrative
Agent shall promptly notify each Lender thereof. Such notice shall describe in
reasonable detail the facts and circumstances giving rise thereto and the date
of such Change in Control and each Lender may, by notice to the Borrower and the
Administrative Agent (a "Termination Notice") given not later than ten days
after the date of such Change of Control, terminate its Commitment, which shall
be terminated, and declare any Loans made by it (together with accrued interest
thereon) and any other amounts payable hereunder for its account to be, and such
Loans and such amounts shall become, due and payable, in each case on

                                       46
<PAGE>

the day following delivery of such Termination Notice (or if such day is not a
Business Day, the next succeeding Business Day), without presentment, demand,
protest or other notice of any kind, all of which are hereby waived by the
Borrower.

(b) If the Commitment of any Lender is terminated pursuant to this Section at a
time when any Letter of Credit is outstanding, then (i) such Lender shall remain
responsible to the LC Issuing Bank with respect to such Letter of Credit to the
same extent as if its Commitment had not terminated and (ii) the Borrower shall
pay to such Lender an amount in immediately available funds (which funds shall
be held as collateral pursuant to arrangements satisfactory to such Lender)
equal to such Lender's Percentage of the aggregate amount available for drawing
under all Letters of Credit outstanding at such time.

(c) If the Commitment of any Lender is terminated pursuant to this Section at a
time when any Swingline Loan is outstanding, then (i) such Lender shall remain
responsible to the Swingline Lender with respect to such Swingline Loan to the
same extent as if its Commitment had not terminated and (ii) the Borrower shall
pay to such Lender an amount in immediately available funds (which funds shall
be held as collateral pursuant to arrangements satisfactory to such Lender)
equal to such Lender's Percentage of the aggregate outstanding principal amount
of such Swingline Loan at such time.

     Section 1.12. Fees. (a) The Borrower shall pay to the Administrative Agent
for the account of each Lender a commitment fee, which shall accrue at the
Applicable Rate on the average daily unused amount of each Commitment of such
Lender during the period from and including the Effective Date to the date on
which such Commitment terminates. Accrued commitment fees will be payable in
arrears on the last day of March, June, September and December of each year and
the day when the Commitments terminate, commencing on the first such day to
occur after the date hereof. All commitment fees will be computed on the basis
of a year of 360 days and will be payable for the actual number of days elapsed
(including the first day but excluding the last day). For purposes of computing
commitment fees, a Lender's Commitment will be deemed to be used to the extent
of its outstanding Revolving Loans and LC Exposure (and its Swingline Exposure
will be disregarded for such purpose).

     (b) The Borrower shall pay (i) to the Administrative Agent for the account
of each Lender a participation fee with respect to its participations in Letters
of Credit, which shall accrue for each day, at the Applicable

                                       47
<PAGE>

Rate that applies to Eurodollar Revolving Loans, on the amount of such Lender's
LC Exposure (excluding any portion thereof attributable to unreimbursed LC
Disbursements) on such day, during the period from the Effective Date to the
later of the date on which such Lender's Commitment terminates and the date on
which such Lender ceases to have any LC Exposure, and (ii) to the LC Issuing
Bank a fronting fee, which shall accrue at the rate or rates per annum
separately agreed upon by the Borrower and such LC Issuing Bank on the average
daily amount of the LC Exposure (excluding any portion thereof attributable to
unreimbursed LC Disbursements) during the period from the Effective Date to the
later of the date on which the Commitments terminate and the date on which there
ceases to be any LC Exposure, as well as the fees separately agreed upon by the
Borrower and such LC Issuing Bank with respect to issuing, amending, renewing or
extending any Letter of Credit or processing drawings thereunder. Participation
fees and fronting fees accrued through the last day of March, June, September
and December of each year will be payable on the third Business Day following
such last day, commencing on the first such date to occur after the Effective
Date; provided that all such fees accrued to the date on which the Commitments
terminate will be payable on such date, and any such fees accruing after such
date will be payable on demand. Any other fees payable to the LC Issuing Bank
pursuant to this subsection will be payable within 10 days after demand. All
such participation fees and fronting fees will be computed on the basis of a
year of 360 days and will be payable for the actual number of days elapsed
(including the first day but excluding the last day).

     (c) The Borrower shall pay to the Administrative Agent, for its own
account, fees payable in the amounts and at the times separately agreed upon by
the Borrower and the Administrative Agent.

     (d) All fees payable hereunder shall be paid on the dates due, in
immediately available funds, to the Administrative Agent (or to the LC Issuing
Bank, in the case of fees payable to it) for distribution, in the case of
commitment fees and participation fees, to the Lenders entitled thereto. Fees
paid shall not be refundable under any circumstances.

     Section 1.13. Interest. (a) The Loans comprising each Base Rate Borrowing
shall bear interest for each day at the Alternate Base Rate plus the Applicable
Rate.

     (b) The Loans comprising each Eurodollar Borrowing shall bear interest for
each Interest Period in effect for such Borrowing at the Adjusted LIBO Rate for
such Interest Period plus the Applicable Rate.

                                       48
<PAGE>

     (c) The Swingline Loans shall bear interest at the rate applicable to Base
Rate Revolving Loans.

     (d) Notwithstanding the foregoing, if any principal of or interest on any
Loan or any fee or other amount payable by the Borrower hereunder is not paid
when due, whether at stated maturity, upon acceleration or otherwise, such
overdue amount shall bear interest, after as well as before judgment, at a rate
per annum equal to (i) in the case of overdue principal of any Loan, 2% plus the
rate that would, in the absence of an Event of Default, be otherwise applicable
to such Loan as provided in the preceding subsections of this Section or (ii) in
the case of any other amount, 2% plus the rate that would, in the absence of an
Event of Default, be applicable to Base Rate Revolving Loans, as provided in
subsection (a) of this Section.

     (e) Interest accrued on each Loan shall be payable in arrears on each
Interest Payment Date for such Loan and upon termination of the Commitments;
provided that (i) interest accrued pursuant to Section 2.13(d) shall be payable
on demand, (ii) upon any repayment of any Loan (except a prepayment of a Base
Rate Revolving Loan before the end of the Revolving Availability Period),
interest accrued on the principal amount repaid shall be payable on the date of
such repayment and (iii) upon any conversion of a Eurodollar Loan before the end
of the current Interest Period therefor, interest accrued on such Loan shall be
payable on the effective date of such conversion.

     (f) All interest hereunder will be computed on the basis of a year of 360
days, except that interest computed by reference to the Alternate Base Rate at
times when the Alternate Base Rate is based on the Prime Rate will be computed
on the basis of a year of 365 days (or 366 days in a leap year), and in each
case will be payable for the actual number of days elapsed (including the first
day but excluding the last day). Each applicable Alternate Base Rate or Adjusted
LIBO Rate shall be determined by the Administrative Agent, and its determination
thereof will be conclusive absent manifest error.

     Section 1.14. Alternate Rate of Interest. If before the beginning of any
Interest Period for a Eurodollar Borrowing:

          (i) deposits in dollars in the applicable amounts are not being
     offered by the Administrative Agent in the London interbank market for such
     Interest Period; or

          (ii) Lenders having 50% or more of the aggregate principal amount of
     the Loans to be included in such Borrowing advise the Administrative Agent
     that the Adjusted LIBO Rate for such Interest Period will not adequately
     and fairly reflect the cost to such Lenders of making or maintaining such
     Loans for such Interest Period;

                                       49
<PAGE>

then the Administrative Agent shall give notice thereof to the Borrower and the
Lenders by telephone or telecopy as promptly as practicable thereafter and,
until the Administrative Agent notifies the Borrower and the Lenders that the
circumstances giving rise to such notice no longer exist, (i) any Interest
Election that requests the conversion of any Borrowing to, or continuation of
any Borrowing as, a Eurodollar Borrowing will be ineffective and (ii) if any
Borrowing Request requests a Eurodollar Borrowing, such Borrowing will be made
as a Base Rate Borrowing.

     Section 1.15. Increased Costs. (a) If any Change in Law shall:

          (i) impose, modify or deem applicable any reserve, special deposit or
     similar requirement against assets of, deposits with or for the account of,
     or credit extended by, any Lender (except any such reserve requirement
     reflected in the Adjusted LIBO Rate) or the LC Issuing Bank; or

          (ii) impose on any Lender or the LC Issuing Bank or the London
     interbank market any other condition affecting this Agreement or Eurodollar
     Loans made by such Lender or any Letter of Credit or participation therein;

and the result of any of the foregoing shall be to increase the cost to such
Lender of making or maintaining any Eurodollar Loan (or of maintaining its
obligation to make Eurodollar Loans) or to increase the cost to such Lender or
the LC Issuing Bank of participating in, issuing or maintaining any Letter of
Credit or to reduce any amount received or receivable by such Lender or the LC
Issuing Bank hereunder (whether of principal, interest or otherwise), then the
Borrower shall pay to such Lender or the LC Issuing Bank, as the case may be,
such additional amount or amounts as will compensate it for such additional cost
incurred or reduction suffered.

     (b) If any Lender or the LC Issuing Bank determines that any Change in Law
regarding capital requirements has or would have the effect of reducing the rate
of return on such Lender's or the LC Issuing Bank's capital or on the capital of
such Lender's or the LC Issuing Bank's holding company, if any, as a consequence
of this Agreement or the Loans made by, or participations in Letters of Credit
held by, such Lender, or the Letters of Credit issued by the LC Issuing Bank, to
a level below that which such Lender or the LC Issuing Bank or such Lender's or
the LC Issuing Bank's holding company could have achieved but for such Change in
Law (taking into consideration such Lender's or the LC Issuing Bank's policies
and the policies of such Lender's or the LC Issuing Bank's holding company with
respect to capital adequacy), then from time to time following receipt of the
certificate referred to in subsection (c) of this Section, the Borrower

                                       50
<PAGE>

shall pay to such Lender or the LC Issuing Bank, as the case may be, such
additional amount or amounts as will compensate it or its holding company for
any such reduction suffered.

     (c) A certificate of a Lender or the LC Issuing Bank setting forth the
amount or amounts necessary to compensate it or its holding company, as the case
may be, as specified in subsection (a) or (b) of this Section shall be delivered
to the Borrower and shall be conclusive absent manifest error. Each such
certificate shall contain a representation and warranty on the part of the
Lender to the effect that such Lender has complied with its obligations pursuant
to Section 2.19 hereof in an effort to eliminate or reduce such amount. The
Borrower shall pay such Lender or the LC Issuing Bank, as the case may be, the
amount shown as due on any such certificate within 10 days after receipt
thereof.

     (d) Failure or delay by any Lender or the LC Issuing Bank to demand
compensation pursuant to this Section will not constitute a waiver of its right
to demand such compensation; provided that the Borrower will not be required to
compensate a Lender or the LC Issuing Bank pursuant to this Section for any
increased cost or reduction incurred more than 180 days before it notifies the
Borrower of the Change in Law giving rise to such increased cost or reduction
and of its intention to claim compensation therefor. However, if the Change in
Law giving rise to such increased cost or reduction is retroactive, then the
180-day period referred to above will be extended to include the period of
retroactive effect thereof.

     Section 1.16. Break Funding Payments. If (a) any principal of any
Eurodollar Loan is repaid on a day other than the last day of an Interest Period
applicable thereto (including as a result of an Event of Default), (b) any
Eurodollar Loan is converted on a day other than the last day of an Interest
Period applicable thereto, (c) the Borrower fails to borrow, convert, continue
or prepay any Revolving Loan on the date specified in any notice delivered
pursuant hereto (regardless of whether such notice may be revoked under Section
2.10(f) and is revoked in accordance therewith), or (d) any Eurodollar Loan is
assigned on a day other than the last day of an Interest Period applicable
thereto as a result of a request by the Borrower pursuant to Section 2.19, then
the Borrower shall compensate each Lender for its loss, cost and expense
attributable to such event. In the case of a Eurodollar Loan, such loss, cost
and expense to any Lender shall be deemed to include an amount determined by
such Lender to be the excess, if any, of (i) the amount of interest that would
have accrued on the principal amount of such Loan had such event not occurred,
at the Adjusted LIBO Rate that would have been applicable to such Loan, for the
period from the date of such event to the end of the then current Interest
Period therefor (or, in the case of a failure to borrow, convert or continue,
the Interest Period that would have begun on the date of such failure), over
(ii) the amount of interest that would accrue on such

                                       51
<PAGE>

principal amount for such period at the interest rate which such Lender would
bid were it to bid, at the beginning of such period, for dollar deposits of a
comparable amount and period from other banks in the eurodollar market. A
certificate of any Lender setting forth any amount or amounts that such Lender
is entitled to receive pursuant to this Section shall be delivered to the
Borrower and shall be conclusive absent manifest error. The Borrower shall pay
such Lender the amount shown as due on any such certificate within 10 days after
receipt thereof.

     Section 1.17. Taxes. (a) All payments by the Borrower under the Loan
Documents shall be made free and clear of and without deduction for any
Indemnified Taxes or Other Taxes; provided that, if the Borrower shall be
required to deduct any Indemnified Taxes or Other Taxes from such payments, then
(i) the sum payable will be increased as necessary so that, after all required
deductions (including deductions applicable to additional sums payable under
this Section) are made, each relevant Lender Party receives an amount equal to
the sum it would have received had no such deductions been made, (ii) the
Borrower shall make such deductions and (iii) the Borrower shall pay the full
amount deducted to the relevant Governmental Authority in accordance with
applicable law.

     (b) In addition, the Borrower shall pay any Other Taxes to the relevant
Governmental Authority in accordance with applicable law.

     (c) The Borrower shall indemnify each Lender Party, within 10 days after
written demand therefor, for the full amount of any Indemnified Taxes or Other
Taxes paid by such Lender Party with respect to any payment by or obligation of
the Borrower under the Loan Documents (including Indemnified Taxes or Other
Taxes imposed or asserted on or attributable to amounts payable under this
Section) and any penalties, interest and reasonable expenses arising therefrom
or with respect thereto, whether or not such Indemnified Taxes or Other Taxes
were correctly or legally imposed or asserted by the relevant Governmental
Authority. A certificate as to the amount of any such payment delivered to the
Borrower by a Lender Party on its own behalf, or by the Administrative Agent on
behalf of a Lender Party, shall be conclusive absent manifest error. If the
Borrower has indemnified any Lender Party pursuant to this Section 2.17(c), such
Lender Party shall take such steps as the Borrower shall reasonably request (at
the Borrower's expense) to assist the Borrower in recovering the Indemnified
Taxes or Other Taxes and any penalties or interest attributable thereto;
provided that no Lender Party shall be required to take any action pursuant to
this Section 2.17(c) unless, in the judgment of such Lender Party, such action
(i) would not subject such Lender Party to any unreimbursed cost or expense and
(ii) would not otherwise be disadvantageous to such Lender Party.

     (d) As soon as practicable after the Borrower pays any Indemnified Taxes or
Other Taxes to a Governmental Authority, the Borrower shall deliver to

                                       52
<PAGE>

the Administrative Agent the original or a certified copy of a receipt issued by
such Governmental Authority evidencing such payment, a copy of the return
reporting such payment or other evidence of such payment reasonably satisfactory
to the Administrative Agent.

     (e) Any Foreign Lender that is entitled to an exemption from or reduction
of withholding tax under the laws of the United States, or any treaty to which
the United States is a party, with respect to payments under this Agreement
shall deliver to the Borrower (with a copy to the Administrative Agent), at the
time or times prescribed by applicable law, such properly completed and executed
documentation prescribed by applicable law or reasonably requested by the
Borrower as will permit such payments to be made without withholding or at a
reduced rate. If any such Foreign Lender becomes subject to any Tax because it
fails to comply with this subsection as and when prescribed by applicable law,
the Borrower shall take such steps (at such Foreign Lender's expense) as such
Foreign Lender shall reasonably request to assist such Foreign Lender to recover
such Tax.

     Section 1.18. Payments Generally; Pro Rata Treatment; Sharing of Set-offs.
(a) The Borrower shall make each payment required to be made by it under the
Loan Documents (whether of principal, interest or fees, or reimbursement of LC
Disbursements, or amounts payable under Section 2.15, 2.16 or 2.17 or otherwise)
before the time expressly required under the relevant Loan Document for such
payment (or, if no such time is expressly required, before 12:00 noon, New York
City time), on the date when due, in immediately available funds, without
set-off or counterclaim. Any amount received after such time on any day may, in
the discretion of the Administrative Agent, be deemed to have been received on
the next succeeding Business Day for purposes of calculating interest thereon.
All such payments shall be made to the Administrative Agent at its offices at
One Chase Manhattan Plaza, 8th Floor, New York, NY 10081, except payments to be
made directly to the LC Issuing Bank or the Swingline Lender as expressly
provided herein and except that payments pursuant to Sections 2.15, 2.16, 2.17
and 9.03 shall be made directly to the Persons entitled thereto and payments
pursuant to other Loan Documents shall be made to the Persons specified therein.
The Administrative Agent shall distribute any such payment received by it for
the account of any other Person to the appropriate recipient promptly after
receipt thereof. Unless otherwise specified herein, if any payment under any
Loan Document shall be due on a day that is not a Business Day, the date for
payment will be extended to the next succeeding Business Day and, if such
payment accrues interest, interest thereon will be payable for the period of
such extension. All payments under each Loan Document shall be made in dollars.

     (b) If at any time insufficient funds are received by and available to the

                                       53
<PAGE>

Administrative Agent to pay fully all amounts of principal, unreimbursed LC
Disbursements, interest and fees then due hereunder, such funds shall be applied
(i) first, to pay interest and fees then due hereunder, ratably among the
parties entitled thereto in accordance with the amounts of interest and fees
then due to such parties, and (ii) second, to pay principal and unreimbursed LC
Disbursements then due hereunder, ratably among the parties entitled thereto in
accordance with the amounts of principal and unreimbursed LC Disbursements then
due to such parties.

     (c) If any Lender shall, by exercising any right of set-off or counterclaim
or otherwise, obtain payment in respect of any principal of or interest on any
of its Loans or any of its participations in LC Disbursements or Swingline Loans
resulting in such Lender receiving payment of a greater proportion of the
aggregate amount of its Loans and participations in LC Disbursements and
Swingline Loans and accrued interest thereon than the proportion received by any
other Lender, then the Lender receiving such greater proportion shall purchase
(for cash at face value) participations in the Loans and participations in LC
Disbursements and Swingline Loans of other Lenders to the extent necessary so
that the benefit of all such payments shall be shared by the Lenders ratably in
accordance with the aggregate amount of principal of and accrued interest on
their respective Loans and participations in LC Disbursements and Swingline
Loans; provided that (i) if any such participations are purchased and all or any
portion of the payment giving rise thereto is recovered, such participations
shall be rescinded and the purchase price restored to the extent of such
recovery, without interest, and (ii) the provisions of this subsection shall not
apply to any payment made by the Borrower pursuant to and in accordance with the
express terms of this Agreement or any payment obtained by a Lender as
consideration for the assignment of or sale of a participation in any of its
Loans or participations in LC Disbursements to any assignee or participant,
other than to the Borrower or any Subsidiary or Affiliate thereof (as to which
the provisions of this subsection shall apply). The Borrower consents to the
foregoing and agrees, to the extent it may effectively do so under applicable
law, that any Lender acquiring a participation pursuant to the foregoing
arrangements may exercise against the Borrower rights of set-off and
counterclaim with respect to such participation as fully as if such Lender were
a direct creditor of the Borrower in the amount of such participation.

     (d) Unless, before the date on which any payment is due to the
Administrative Agent for the account of one or more Lender Parties hereunder,
the Administrative Agent receives from the Borrower notice that the Borrower
will not make such payment, the Administrative Agent may assume that the
Borrower has made such payment on such date in accordance herewith and may, in
reliance on such assumption, distribute to each relevant Lender Party the amount
due to it. In such event, if the Borrower has not in fact made such payment,
each Lender Party severally agrees to repay to the Administrative Agent
forthwith on demand the amount so distributed to such Lender Party with interest

                                       54
<PAGE>

thereon, for each day from and including the day such amount is distributed to
it to but excluding the day it repays the Administrative Agent, at the greater
of the Federal Funds Effective Rate and a rate determined by the Administrative
Agent in accordance with banking industry rules on interbank compensation.

     (e) If any Lender fails to make any payment required to be made by it
pursuant to Section 2.04(e), 2.05(d), 2.05(e), 2.06(b), 2.18(d) or 9.03(c), the
Administrative Agent may, in its discretion (notwithstanding any contrary
provision hereof), apply any amounts thereafter received by the Administrative
Agent for the account of such Lender to satisfy such Lender's obligations under
such Sections until all such unsatisfied obligations are fully paid.

     Section 1.19. Lender's Obligation to Mitigate; Replacement of Lenders . (a)
If any Lender requests compensation under Section 2.15, or if the Borrower is
required to pay any additional amount to any Lender or any Governmental
Authority for the account of any Lender pursuant to Section 2.17, then such
Lender shall use all commercially reasonable efforts to mitigate or eliminate
the amount of such compensation or additional amount, including without
limitation, by designating a different lending office for funding or booking its
Loans hereunder or by assigning its rights and obligations hereunder to another
of its offices, branches or affiliates; provided that no Lender shall be
required to take any action pursuant to this Section 2.19(a) unless, in the
judgment of such Lender, such designation or assignment or other action (i)
would eliminate or reduce amounts payable pursuant to Section 2.15 or 2.17, as
the case may be, in the future, (ii) would not subject such Lender to any
unreimbursed cost or expense and (iii) would not otherwise be disadvantageous to
such Lender. The Borrower shall pay all reasonable costs and expenses incurred
by any Lender in connection with any such designation or assignment.

     (b) If any Lender requests compensation under Section 2.15, or if the
Borrower is required to pay any additional amount to any Lender or any
Governmental Authority for the account of any Lender pursuant to Section 2.17,
or if any Lender defaults in its obligation to fund Loans hereunder, then the
Borrower may, at its sole expense and effort, upon notice to such Lender and the
Administrative Agent, require such Lender to assign, without recourse (in
accordance with and subject to the restrictions contained in Section 9.04), all
its interests, rights and obligations under this Agreement to an assignee that
shall assume such obligations (which assignee may be another Lender, if a Lender
accepts such assignment); provided that (i) the Borrower shall have received the
prior written consent of the Administrative Agent (and, if a Commitment is being
assigned, the LC Issuing Bank and the Swingline Lender), which consents shall
not unreasonably be withheld, (ii) such Lender shall have received payment of an
amount equal to the outstanding principal of its Loans and participations in LC
Disbursements and Swingline Loans, accrued interest thereon, accrued fees and

                                       55
<PAGE>

all other amounts payable to it hereunder, from the assignee (to the extent of
such outstanding principal and accrued interest and fees) or the Borrower (in
the case of all other amounts) and (iii) in the case of any such assignment
resulting from a claim for compensation under Section 2.15 or payments required
to be made pursuant to Section 2.17, such assignment will result in a material
reduction in such compensation or payments. A Lender shall not be required to
make any such assignment if, prior thereto, as a result of a waiver by such
Lender or otherwise, the circumstances entitling the Borrower to require such
assignment cease to apply.

     Section 1.20. Optional Increase in Commitments. At any time, if no Default
shall have occurred and be continuing (or would result after giving effect
thereto), the Borrower, may, if it so elects, increase the aggregate amount of
the Commitments (each such increase to be in an aggregate amount that is an
integral multiple of $1,000,000 and not less than $5,000,000), either by
designating a financial institution not theretofore a Lender to become a Lender
(such designation to be effective only with the prior written consent of the
Administrative Agent and each LC Issuing Bank, which consent will not be
unreasonably withheld or delayed, and only if such financial institution accepts
a Commitment in an aggregate amount that is an integral multiple of $1,000,000
and not less than $5,000,000), or by agreeing with an existing Lender that such
Lender's Commitment shall be increased. Upon execution and delivery by the
Borrower and such Lender or other financial institution of an instrument (a
"Commitment Acceptance") in form reasonably satisfactory to the Administrative
Agent, such existing Lender shall have a Commitment as therein set forth or such
other financial institution shall become a Lender with a Commitment as therein
set forth and all the rights and obligations of a Lender with such a Commitment
hereunder; provided:

     (a) that the Borrower shall provide prompt notice of such increase to the
Administrative Agent, who shall promptly notify the Lenders;

     (b) that the Borrower shall have delivered to the Administrative Agent a
copy of the Commitment Acceptance;

     (c) that the amount of such increase, together with all other increases in
the aggregate amount of the Commitments pursuant to this Section 2.20 since the
date of this Agreement, does not exceed $150,000,000;

     (d) that, before and after giving effect to such increase, the
representations and warranties of the Borrower contained in Article 3 of this
Agreement shall be true and correct; and

     (e) that the Administrative Agent shall have received such evidence
(including an opinion of Borrower's counsel) as it may

                                       56
<PAGE>

reasonably request to confirm the Borrower's due authorization of the
transactions contemplated by this Section 2.20 and the validity and
enforceability of the obligations of the Borrower resulting therefrom.

     On the date of any such increase, the Borrower shall be deemed to have
represented to the Administrative Agent and the Lenders that the conditions set
forth in clauses (a) through (e) above have been satisfied.

     Upon any increase in the aggregate amount of the Commitments pursuant to
this Section 2.20:

          (x) within five Domestic Business Days, in the case of any Base Rate
     Borrowings then outstanding, and at the end of the then current Interest
     Period with respect thereto, in the case of any Eurodollar Borrowings then
     outstanding, the Borrower shall prepay such Borrowing in its entirety and,
     to the extent the Borrower elects to do so and subject to the conditions
     specified in Article 4, the Borrower shall reborrow Loans from the Lenders
     in proportion to their respective Commitments after giving effect to such
     increase, until such time as all outstanding Loans are held by the Lenders
     in such proportion; and

          (y) each existing Lender whose Commitment has not increased pursuant
     to this Section 2.20 (each, a "Non-Increasing Lender") shall be deemed,
     without further action by any party hereto, to have sold to each Lender
     whose Commitment has been assumed or increased under this Section 2.20
     (each, an "Increased Commitment Lender"), and each Increased Commitment
     Lender shall be deemed, without further action by any party hereto, to have
     purchased from each Non-Increasing Lender, a participation (on the terms
     specified in Section 2.05 and 2.04, respectively) in each outstanding
     Letter of Credit and each Swingline Loan in which such Non-Increasing
     Lender has acquired a participation in an amount equal to such Increased
     Commitment Lender's Percentage thereof, until such time as all LC Exposures
     and Swingline Exposures are held by the Lenders in proportion to their
     respective Commitments after giving effect to such increase.

                                    ARTICLE 2

                         REPRESENTATIONS AND WARRANTIES

     The Borrower represents and warrants to the Lender Parties that:

                                       57
<PAGE>

     Section 2.1. Organization; Powers. The Borrower and each of its Restricted
Subsidiaries is duly organized, validly existing and in good standing under the
laws of the jurisdiction of its organization, has all requisite power and
authority to carry on its business as now conducted and, except where failures
to do so, in the aggregate, could not reasonably be expected to result in a
Material Adverse Effect, is qualified to do business in, and is in good standing
in, every jurisdiction where such qualification is required.

     Section 2.2. Authorization; Enforceability. The Financing Transactions to
be entered into by the Borrower are within its corporate, limited liability
company or similar company powers and have been duly authorized by all necessary
corporate, limited liability company (or similar) action and, if required,
stockholder or equity holder action. This Agreement has been duly executed and
delivered by the Borrower and constitutes, and each other Loan Document to which
the Borrower is to be a party, when executed and delivered by the Borrower, will
constitute, a legal, valid and binding obligation of the Borrower, as the case
may be, in each case enforceable in accordance with its terms, subject to
applicable bankruptcy, insolvency, reorganization, moratorium and other laws
affecting creditors' rights generally and subject to general principles of
equity, regardless of whether considered in a proceeding in equity or at law.

     Section 2.3. Governmental Approvals; No Conflicts. The Financing
Transactions (a) do not require any consent or approval of, registration or
filing with, or other action by, any Governmental Authority, except (i) such as
have been obtained or made and are in full force and effect and (ii) filings
necessary to perfect the Transaction Liens, (b) will not violate any applicable
law or regulation or the charter, by-laws, limited liability company agreement
or other organizational documents of the Borrower or any order of any
Governmental Authority, (c) will not violate or result in a default under any
indenture, agreement or other instrument binding upon the Borrower or any of its
properties, or give rise to a right thereunder to require the Borrower to make
any payment, and (d) will not result in the creation or imposition of any Lien
(other than the Transaction Liens) on any property of the Borrower.

     Section 2.4. Financial Statements; No Material Adverse Change . (a) The
Borrower has heretofore furnished to the Lenders (i) USX Corporation's 2000 Form
10-K containing the audited consolidated balance sheet of the U.S. Steel Group
as of December 31, 2000 and the related consolidated statements of income and
cash flows for the Fiscal Year then ended, reported on by PricewaterhouseCoopers
LLP, independent public accountants, and (ii) USX Corporation's Latest Form 10-Q

                                       58
<PAGE>

U.S. Steel Group as of September 30, 2001 and the related consolidated
statements of income and cash flows for the Fiscal Quarter then ended and for
the portion of the Fiscal Year then ended, all certified by its chief financial
officer. Such financial statements present fairly, in all material respects, the
consolidated financial position of the U.S. Steel Group as of such dates and its
consolidated results of operations and cash flows for such periods in accordance
with GAAP, subject to normal year-end adjustments and the absence of footnotes
in the case of the statements referred to in clause (ii) above.

     (b) The Borrower has heretofore furnished to the Lenders its pro forma
consolidated balance sheet as of June 30, 2001, prepared giving effect to the
Financing Transactions as if the Financing Transactions had occurred on such
date. Such pro forma consolidated balance sheet (i) has been prepared in good
faith based on the same assumptions used to prepare the pro forma financial
statements included in the Information Memorandum (which assumptions are
believed by the Borrower to be reasonable), (ii) is based on the best
information available to the Borrower after due inquiry, (iii) accurately
reflects all adjustments necessary to give effect to the Financing Transactions
and (iv) presents fairly, in all material respects, the pro forma consolidated
financial position of the Borrower and its Subsidiaries as of June 30, 2001 as

     (c) Since December 31, 2000, there has been no material adverse change in
the business, operations, properties, assets, financial condition, contingent
liabilities or material agreements of the Borrower and its Subsidiaries, taken
as a whole, except as disclosed prior to the Effective Date in USX Corporation's
2000 Form 10-K, USX Corporation's Latest Form 10-Q or USX Corporation's Latest

     Section 2.5. Security Documents. The Security Documents create valid
security interests in the Collateral purported to be covered thereby, which
security interests are and will remain perfected security interests, prior to
all other Liens, other than Liens permitted under Section 6.02. Each of the
representations and warranties made by the Borrower in the Security Documents to
which it is a party is true and correct in all material respects.

     Section 2.6. Borrower's Subsidiaries. As of the Effective Date, the
Borrower has no Subsidiaries other than those set forth on Schedule 3.06. Each
Subsidiary identified on Schedule 3.06 is a Restricted Subsidiary.

Act or (v) the Borrower's and USX Corporation's registration statement on Form
S-4, as filed with the SEC on October 12, 2001, there is no action, suit,
arbitration proceeding or other proceeding, inquiry or investigation, at law or
in equity, before or by any arbitrator or Governmental Authority pending against
the Borrower or of which the Borrower has otherwise received official notice or
which, to the knowledge of the Borrower, is threatened against the Borrower (i)
as to which there is a reasonable possibility of an unfavorable decision, ruling
or finding which would reasonably be expected to result in a Material Adverse
Effect or (ii) that involves any of the Loan Documents or the Financing
Transactions.

     (b) Except as set forth in USX Corporation's 2000 Form 10-K, USX
Corporation's Latest Form 10-Q or USX Corporation's Latest Proxy Statement, the
Borrower does not presently anticipate that remediation costs and penalties
associated with any Environmental Law, to the extent not previously provided
for, will have a Material Adverse Effect.

     Section 2.8. Compliance with Laws and Agreements. The Borrower is in
compliance with all laws, regulations and orders of any Governmental Authority
applicable to it or its property (including (i) all Environmental Laws, (ii)
ERISA, (iii) applicable laws, regulations and orders dealing with intellectual
property, and (iv) the Fair Labor Standards Act and other applicable law dealing
with such matters) and all indentures, agreements and other instruments binding

an "investment company" or a company "controlled" by an "investment company"
within the meaning of the Investment Company Act of 1940, as amended or (b) a

company", within the meaning of the Public Utility Holding Company Act of 1935,
as amended.

     Section 2.10. ERISA. No ERISA Event has occurred or is reasonably expected
to occur that, when taken together with all other ERISA Events for which
liability is reasonably expected to occur, would reasonably be expected to
result in a Material Adverse Effect.

     Section 2.11. Regulation U. Neither the Borrower nor any of its
Subsidiaries is engaged principally, or as one of its important activities, in
the business of extending credit for the purpose of purchasing or carrying
margin stock (within the meaning of Regulation U).

<PAGE>

     Section 2.12. Disclosure. The Borrower has disclosed to the Lenders all
agreements, instruments and corporate or other restrictions to which it is
subject, and all other matters known to it, that, individually or in the
aggregate, would reasonably be expected to result in a Material Adverse Effect.
The Information Memorandum and any other written information (other than
projected financial information) set forth in (a) USX Corporation's Proxy
Statement on Form 14A filed with the SEC on September 20, 2001, (b) the
Borrower's Confidential Offering Circulars dated July 24, 2001 and September 6,
2001 relating to the Borrower's 10-3/4% Senior Notes, (c) the Borrower's
roadshow materials presented in connection with its July, 2001 and September,

Borrower's inventory that has been made available by or on behalf of the
Borrower to the Arranger, any Agent or any Lender in connection with the
negotiation of this Agreement or any other Loan Document or delivered hereunder
or thereunder, is complete and correct in all material respects and does not
contain any untrue statement of a material fact or omit to state a material fact
necessary in order to make the statements contained therein not materially
misleading in light of the circumstances under which such statements are made;
provided that, with respect to projected financial information, the Borrower
represents only that such information was prepared in good faith based on
assumptions believed to be reasonable at the time.

     Section 2.13. Senior Debt. The Secured Obligations constitute "Secured
Indebtedness" and "Senior Indebtedness" under and as defined in the Senior
Unsecured Debt Documents.

     Section 2.14. Processing of Receivables. In the ordinary course of its
business, the Borrower processes its accounts receivable in a manner such that
(i) each payment received by the Borrower in respect of accounts receivables is
allocated to a specifically identified invoice or invoices, which invoice or
invoices corresponds to a particular account receivable owing to the Borrower
and (ii) if, at any time, less than 100% of the accounts receivables to the
Borrower are included in a Receivables Financing, payments received in respect
of those accounts receivable included in a Receivables Financing would be
identifiable and separable from payments received in respect of accounts
receivable not so included in a Receivables Financing.

     Section 2.15. Senior Unsecured Debt Documents. The Borrower has heretofore
furnished to the Lenders true and correct copies of all Senior Unsecured Debt
Documents.

occur on the Effective Date are consummated and after giving effect to the
application of the proceeds of each Loan made on the Effective Date and after
giving effect to the application of the proceeds of each Loan made on any other
date, (a) the fair value of the assets of the Borrower, at a fair valuation,
will exceed its debts and liabilities, subordinated, contingent or otherwise;
(b) the Borrower will be able to pay its debts and liabilities, subordinated,
contingent or otherwise, as such debts and liabilities become absolute and
matured; and (c) the Borrower will not have unreasonably small capital with
which to conduct the business in which it is engaged as such business is now
conducted and proposed to be conducted after the Effective Date.

                                    ARTICLE 3

effective until the date on which each of the following conditions is satisfied
(or waived in accordance with Section 9.02):

          (a) The Administrative Agent (or its counsel) shall have received
     counterparts hereof signed by the Borrower and each of the Lenders listed
     on the signature pages hereof (or, in the case of any party as to which an
     executed counterpart shall not have been received, receipt by the
     Administrative Agent in form satisfactory to it of telex, facsimile or
     other written confirmation from such party that it has executed a
     counterpart hereof).

          (b) The Administrative Agent shall have received favorable written
     opinions (in each case, addressed to the Administrative Agent and the
     Lenders and dated the Effective Date) of Berry & Associates, special
     counsel for the Borrower, and the General Counsel or an Assistant General
     Counsel of the Borrower, (i) which opinions are substantially in the form
     of Exhibit B-1 and Exhibit B-2, respectively, and (ii) covering such other
     matters relating to the Borrower, the Loan Documents or the Financing
     Transactions as the Required Lenders shall reasonably request. The Borrower
     requests such counsel to deliver such opinion.

          (c) The Administrative Agent shall have received such documents and
     certificates as the Administrative Agent or its counsel may reasonably
     request relating to the organization, existence and good standing of the
     Borrower, the authorization for and validity of the

                                       62
<PAGE>

     Financing Transactions and any other legal matters relating to the

     Administrative Agent of their determination that, since December 31, 2000,
     any event, development or circumstance has occurred that has had or would
     reasonably be expected to have a Material Adverse Effect, other than those
     events, developments and circumstances that have been disclosed (i) to the

     Statement or the Borrower's and USX Corporation's registration statement on
     Form S-4 filed on October 12, 2001.

          (f) The fact that neither the Arranger nor the Administrative Agent
     shall have become aware of any information or other matter affecting the
     Borrower or the Financing Transactions which was in existence prior to the
     date of this Agreement and is inconsistent in a material and adverse manner
     with any such information or other matter disclosed to them prior to the
     date of this Agreement.

          (g) The Borrower shall have paid all fees and other amounts due and
     payable to the Lender Parties on or before the Effective Date, including,
     to the extent invoiced, all out-of-pocket expenses (including fees, charges
     and disbursements of counsel) required to be reimbursed or paid by the

     in the jurisdictions contemplated by the Perfection Certificate and copies
     of the financing statements (or similar documents) disclosed by such search
     and evidence reasonably satisfactory to the Administrative Agent that the
     Liens indicated by such financing statements (or similar documents) are
     permitted by Section 6.02 or have been released.

          (i) The Administrative Agent shall have received evidence

                                       63

     is in effect.

          (j) All consents and approvals required to be obtained from any
     Governmental Authority or other Person in connection with the Financing
     Transactions shall have been obtained and be in full force and effect,
     except where failure to obtain such approval or consent would not have a
     Material Adverse Effect.

          (k) The Lenders shall have received (i) a monthly computation of the
     Borrower's liquidity position (including cash, receivables, inventory and
     borrowings) for each month of Fiscal Year 2001 that ends at least 20 days

          (ii) within two Business Days of any request therefor, such other
     information in such detail concerning the amount, composition and manner of
     calculation of the Borrowing Base as any Lender may reasonably request.

     Section 4.2. Notice of Material Events. The Borrower will furnish to the
Administrative Agent and each Lender prompt written notice of the following:

          (a) the occurrence of any Default;

          (b) the filing or commencement of any action, suit or proceeding by or
     before any arbitrator or Governmental Authority against or affecting the
     Borrower or any Restricted Subsidiary or any Affiliate thereof that, if
     adversely determined, could reasonably be expected to result in a Material
     Adverse Effect;

          (c) the occurrence of any ERISA Event that, alone or together with any
     other ERISA Events that have occurred, could reasonably be expected to
     result in liabilities of the Borrower and its Restricted Subsidiaries in an
     aggregate amount exceeding $50,000,000;

          (d) the occurrence of any change in the Borrower's Senior Debt Ratings
     by either Moody's or S&P; and

                                       69
<PAGE>

     expected to result in, a Material Adverse Effect.

Each notice delivered under this Section shall be accompanied by a statement of
a Financial Officer or other executive officer of the Borrower setting forth the
details of the event or development requiring such notice and any action taken
or proposed to be taken with respect thereto.

     Section 4.3. Information Regarding Collateral. (a) The Borrower will
furnish to the Administrative Agent prompt written notice of any change in (i)
the Borrower's corporate name or any trade name used to identify it in the

place of business, or any office or facility at which Collateral owned by it is
located (including the establishment of any such new office or facility), (ii)
the Borrower's identity or corporate structure, (iii) the Borrower's State
Organizational Identification Number (or Charter Number) and (iv) the Borrower's
Federal Taxpayer Identification Number. The Borrower will not effect or permit
any change referred to in the preceding sentence unless all filings have been
made under the Uniform Commercial Code and all other actions have been taken
that are required so that such change will not at any time adversely affect the
validity, perfection or priority of any Transaction Lien on any of the
Collateral. The Borrower will also promptly notify the Administrative Agent if
any material portion of the Collateral is damaged or destroyed.

     (b) Each year, at the time annual financial statements with respect to the
preceding Fiscal Year are delivered pursuant to Section 5.01(a)(i), the Borrower
will deliver to the Administrative Agent a certificate of a Financial Officer
and the chief legal officer (or other in-house counsel) of the Borrower (i)
setting forth the information required pursuant to Sections A.1, A.2 and B.1 of
the Perfection Certificate or confirming that there has been no change in such
information since the date of the Perfection Certificate delivered on the
Effective Date or the date of the most recent certificate delivered pursuant to
this subsection and (ii) certifying that all Uniform Commercial Code financing
statements (including fixture filings, as applicable) or other appropriate
filings, recordings or registrations, including all refilings, rerecordings and
reregistrations, containing a description of the Collateral have been filed of
record in each appropriate office in each jurisdiction identified pursuant to
clause (i) above to the extent necessary to protect and perfect the Transaction
Liens for a period of at least 18 months after the date of such certificate
(except as noted therein with respect to any continuation statements to be filed
within such period).

     (c) The Borrower will furnish to the Administrative Agent, the Collateral
Agent and the Co-Collateral Agent prompt written notice of the occurrence of any
"Termination Event" (as defined in the Effective Date Receivables Financing).
From and after the occurrence of any such Termination Event, the Borrower shall
furnish to the Administrative Agent and the Collateral

                                       70
<PAGE>

Agent a daily written report reflecting then current amortization of the
Effective Date Receivables Financing. On any date when the Effective Date
Receivables Financing shall have terminated and the payment of all obligations
owing by the Borrower and its Subsidiaries in respect thereof shall have been
paid in full, the Borrower shall provide prompt written notice thereof to the
Administrative Agent, the Collateral Agent and the Co-Collateral Agent.

     (d) Upon the request of any Lender, the Borrower will furnish to the
Collateral Agent copies of any servicer reports that have been furnished to
JPMorgan Chase Bank or The Bank of Nova Scotia, in their respective capacities
as agents, under the Effective Date Receivables Financing.

     Section 4.4. Existence; Conduct of Business. The Borrower will, and will
cause each of its Subsidiaries (other than any Unrestricted Subsidiary) to, do
or cause to be done all things necessary to preserve, renew and keep in full
force and effect its legal existence and the rights, licenses, permits,
privileges, franchises, patents, copyrights, trademarks and trade names material
to the conduct of its business; provided that the foregoing shall not prohibit
any merger, consolidation, liquidation or dissolution permitted under Section
6.03.

     Section 4.5. Payment of Obligations. The Borrower will, and will cause each
of its Subsidiaries (other than any Unrestricted Subsidiary) to, pay all of its
material Debt and other material obligations, including Tax liabilities, before
the same shall become delinquent or in default, except where (a) the validity or
amount thereof is being contested in good faith by appropriate proceedings, (b)
the Borrower or such Subsidiary has set aside on its books adequate reserves
with respect thereto in accordance with GAAP, (c) such contest effectively
suspends collection of the contested obligation and the enforcement of any Lien
securing such obligation and (d) the failure to make payment pending such
contest would not reasonably be expected to result in a Material Adverse Effect.

     Section 4.6. Maintenance of Properties. The Borrower will, and will cause
each of its Subsidiaries (other than any Unrestricted Subsidiary) to, maintain
all property material to the conduct of its business in good working order and
condition, ordinary wear and tear excepted.

     Section 4.7. Insurance. (a) The Borrower will, and will cause each of its
Subsidiaries (other than any Unrestricted Subsidiary) to maintain, at its sole
cost and expense, insurance coverage (x) as in effect on the date of the
Agreement and described in Schedule 5.07 or (y) otherwise with financially sound
and reputable insurers (which insurers shall be reasonably acceptable to the
Administrative Agent, the Collateral Agent and the Co-Collateral Agent) in such
amounts, and with such deductibles (including provisions for self-insurance), as
are set forth on Schedule 5.07

                                       71
<PAGE>

hereof. If at any time the Borrower is unable to maintain (or cause to be
maintained) such insurance coverage with the deductibles shown on Schedule 5.07
at favorable premiums, it shall so advise the Administrative Agent, the
Collateral Agent and the Co-Collateral Agent in writing at least 30 days prior
to the expiration of the then current policy (enclosing with such notice copies
of any proposals from insurers regarding the insurance coverage in question as
well as the Borrower's recommendations with respect thereto). The Administrative
Agent shall promptly (but in no event later than 15 days from receipt of such
notice) advise the Borrower of the requirements of the Administrative Agent
(which requirements shall be determined in good faith by mutual agreement among
the Administrative Agent, the Collateral Agent and the Co-Collateral Agent)
regarding such insurance coverage, and the Borrower shall be bound to adhere to
such requirements. If the Borrower at any time or times hereafter fails to
obtain or maintain the insurance coverage required pursuant to this Section 5.07
or to pay all premiums relating thereto, the Collateral Agent may at any time or
times thereafter obtain and maintain such required insurance coverage and pay
such premiums and take such other actions with respect thereto that the
Collateral Agent deems reasonably advisable. The Collateral Agent shall not have
any obligation to obtain insurance for the Borrower or any of its Subsidiaries
or to pay any premiums therefor. By doing so, the Collateral Agent shall not be
deemed to have waived any Default arising from failure of the Borrower to
maintain (or cause to be maintained) such insurance or to pay (or cause to be
paid) any premiums therefor. All sums so disbursed, including reasonable
attorneys' fees, court costs and other charges related thereto, shall be payable
on demand by the Borrower to the Administrative Agent and shall be additional
obligations hereunder secured by the Collateral. The Collateral Agent and the
Co-Collateral Agent reserve the right at any time upon any change in the
Borrower's risk profile to require additional insurance coverages and limits of
insurance to, in such Agents' reasonable opinion, adequately protect the
interests of the Lender Parties in all or any portion of the Collateral.

     (b) Property damage policies maintained with respect to any Collateral
shall be endorsed or otherwise amended to include a lenders' loss payable
clause, in each case in favor of the Collateral Agent and providing for losses
thereunder to be payable to the Collateral Agent or its designee as loss payee
and (ii) a provision to the effect that none of the Administrative Agent, the
Collateral Agent, the Co-Collateral Agent nor any other Lender Party shall be a
coinsurer. Commercial general liability policies shall be endorsed to name the
Collateral Agent as an additional insured. Each such policy referred to in this
subsection also shall provide that it shall not be canceled, modified or not
renewed (i) by reason of nonpayment of premium except upon at least 10 days'
prior written notice thereof by the insurer to the Collateral Agent (giving the
Collateral Agent the right to cure defaults in the payment of premiums) or (ii)
for any other reason

                                       72
<PAGE>

except upon at least 30 days' prior written notice thereof by the insurer to the
Collateral Agent. The Borrower shall deliver to the Collateral Agent, prior to
the cancellation, modification or nonrenewal of any such policy of insurance, a
copy of a renewal or replacement policy (or other evidence of renewal of a
policy previously delivered to the Collateral Agent) together with evidence
reasonably satisfactory to the Collateral Agent of payment of the premium
therefor.

     Section 4.8. Casualty and Condemnation. The Borrower will furnish to the
Administrative Agent, the Collateral Agent and the Lenders prompt written notice
of any casualty or other insured damage to any material portion of the
Collateral or the commencement of any action or proceeding for the taking of any
Collateral or any part thereof or interest therein under power of eminent domain
or by condemnation or similar proceeding.

     Section 4.9. Proper Records; Rights to Inspect and Appraise. (a) The
Borrower will, and will cause each of its Subsidiaries (other than any
Unrestricted Subsidiary) to, keep proper books of record and account in which
complete and correct entries are made of all transactions relating to its
business and activities. The Borrower will, and will cause each of its
Subsidiaries (other than any Unrestricted Subsidiary) to, permit any
representatives designated by the Administrative Agent, the Collateral Agent,
the Co-Collateral Agent or any Lender, upon reasonable prior notice, to visit
and inspect its properties, to examine and make extracts from its books and
records, and to discuss its affairs, finances and condition with its officers
and independent accountants, all at such reasonable times and as often as
reasonably requested.

     (b) The Borrower will, and will cause each of its Subsidiaries (other than
any Unrestricted Subsidiary) to, permit the Collateral Agent and/or the
Co-Collateral Agent and any representatives designated by either of them
(including any consultants, accountants, lawyers and appraisers retained by the
Collateral Agent) to conduct collateral reviews and evaluations and appraisals
of the assets included in the Borrowing Base and the Borrower's computation of
the Borrowing Base, all at such reasonable times and as often as reasonably
requested. The Borrower shall pay the documented fees and expenses of employees
of the Collateral Agent (including reasonable and customary internally allocated
fees of such employees incurred in connection with periodic collateral
evaluations and appraisals and internally allocated monitoring fees associated
with the Collateral Agent's "collateral agent services group" or similar body)
or any representatives (including any inventory appraisal firm) retained by the
Collateral Agent to conduct any such evaluation or appraisal; provided the
Borrower shall not be required to pay such fees and expenses of collateral
reviews and appraisals performed by the Collateral Agent and the Co-Collateral
Agent, except (i) in respect of one such collateral review and one such
appraisal performed by the Collateral Agent (or, at the option of the
Co-Collateral Agent,

                                       73
<PAGE>

by the Collateral Agent and the Co-Collateral Agent together) in any calendar
year, and (ii) in respect of up to four such collateral reviews and four such
appraisals performed by the Collateral Agent (or, at the option of the
Co-Collateral Agent, by the Collateral Agent and the Co-Collateral Agent
together) at such times as Facility Availability (calculated for purposes hereof
without giving effect to the Availability Block) is less than $100,000,000, and
(iii) in respect of any such collateral reviews and such collateral appraisals
performed by the Collateral Agent and the Co-Collateral Agent during the
continuance of a Default or Event of Default; and provided further that the
Borrower shall not be required to pay the fees and expenses of inventory
appraisal firms hired by the Collateral Agent, except (i) in respect of one
inventory appraisal per calendar year during the term of this Agreement, (ii) in
respect of up to four inventory appraisals per calendar year at such times as
Facility Availability (calculated for this purpose without giving effect to the
Availability Block) is less than $100,000,000, and (iii) in respect of any one
or more additional inventory appraisals conducted at the request of the
Collateral Agent during the continuance of a Default or Event of Default. The
Collateral Agent, the Co-Collateral Agent and any representative designated by
either of them to conduct such collateral reviews, evaluations and appraisals
shall, during any review, inspection or other activity performed at any of the
Borrower's plant sites, (x) be accompanied at all times by a plant safety
representative (and the Borrower hereby agrees to cause such a plant safety
representative to be available for such purpose at such reasonable hours as may
be requested and upon reasonable prior notice) and (y) comply at all times with
the Borrower's rules regarding safety and security to the extent that the
Collateral Agent, Co-Collateral Agent or representative has been notified of
such rules. In connection with any collateral monitoring or review and appraisal
relating to the computation of the Borrowing Base, the Borrower shall make
adjustments to the Borrowing Base (which may include maintaining additional
reserves or modifying the eligibility criteria for components of the Borrowing
Base) to the extent required by the Collateral Agent or the Required Lenders as
a result of any such monitoring, review or appraisal. The Collateral Agent and
the Co-Collateral Agent shall furnish to the Administrative Agent (for delivery
to each Lender) a copy of the final written collateral review or appraisal
report prepared in connection with such monitoring, review or appraisal.

     Section 4.10. Compliance with Laws. The Borrower will, and will cause each
of its Subsidiaries (other than any Unrestricted Subsidiary) to, comply with all
laws, rules, regulations and orders of any Governmental Authority (including all
Environmental Laws and ERISA and the respective rules and regulations
thereunder) applicable to it or its property, other than such laws, rules or

     Section 4.11. Use of Proceeds and Letters of Credit. The proceeds of the
Revolving Loans and Swingline Loans will be used only to finance the general
corporate purposes (including working capital needs) of the Borrower. No part of
the proceeds of any Loan will be used, directly or indirectly, for any purpose
that entails a violation of any of the Regulations of the Federal Reserve Board,
including Regulations T, U and X. Letters of Credit will be requested and used
only to finance the general corporate purposes (including working capital needs)
of the Borrower, and will not be used, whether directly or indirectly, for any

Reserve Board, including regulations T, U and X.

     Section 4.12. Further Assurances. (a) The Borrower will execute and deliver
any and all further documents, financing statements, agreements and instruments,
and take all such further actions (including the filing and recording of
financing statements and other documents), that may be required under any
applicable law, or that the Administrative Agent, the Collateral Agent or the
Required Lenders may reasonably request, to cause the Collateral Requirement to
be and remain satisfied, all at the Borrower's expense. The Borrower will
provide to the Collateral Agent, from time to time upon request, evidence
reasonably satisfactory to the Collateral Agent as to the perfection and
priority of the Transaction Liens created or intended to be created by the
Security Documents.

     (b) If, on the date when all of the Commitments are terminated (whether
pursuant to Section 2.08 or otherwise), any Letter of Credit remains
outstanding, the Borrower shall deposit in the Cash Collateral Account on such
date an amount in cash equal to 102% of the total LC Exposure as of such date
plus any accrued and unpaid interest thereon. Any amount so deposited (including
any earnings thereon) will be withdrawn from the Cash Collateral Account by the
Administrative Agent and applied to pay LC Reimbursement Obligations as they
become due; provided that at such time as all outstanding Letters of Credit have
expired, and all LC Reimbursement Obligations (plus accrued and unpaid interest
thereon) have been paid in full, such amount, to the extent not therefore
applied, shall be returned to the Borrower.

     Section 4.13. Amendments to Effective Date Receivables Financing. The
Borrower shall (a) provide the Administrative Agent and the Collateral Agent
with written notice of any proposed amendment, modification or other change to,
and each consent to a departure from, the terms or provisions of the Effective
Date Receivables Financing and (b) promptly following the effectiveness thereof,
provide the Administrative Agent and the Collateral Agent with a copy of each
such amendment, modification or other change to, and each such consent to a
departure from, the terms or provisions of the Effective Date Receivables
Financing. The Borrower shall not, without the prior written consent of the
Required

                                       75
<PAGE>

Lenders, amend, modify or otherwise change or obtain a consent to a departure
from (i) the definitions of "USS Credit Agreement" or "USS Security Agreement"
contained in the Receivables Purchase Agreement or (ii) any other provision of
(including by the addition of a provision) the Effective Date Receivables
Financing which could in any way impair the interests of the Lender Parties in
the Collateral.

     Section 4.14. Designation of Subsidiaries. The Borrower's board of
directors may at any time designate any Restricted Subsidiary as an Unrestricted
Subsidiary or any Unrestricted Subsidiary as a Restricted Subsidiary; provided
that (i) immediately before and after such designation, no Default shall have
occurred and be continuing (including, without limitation, any Default as a
result of a breach of the covenants set forth in Sections 6.01, 6.02 and 6.04),
(ii) immediately after giving effect to such designation, the Borrower shall be
in compliance, on a pro forma basis, with the covenants set forth in Section
6.13 and Section 6.14 (and, as a condition precedent to the effectiveness of any
such designation, the Borrower shall deliver to the Administrative Agent a copy
of the board resolution giving effect to such designation and a certificate of a
Financial Officer setting forth in reasonable detail the calculations
demonstrating such compliance), (iii) no Subsidiary may be designated as an
Unrestricted Subsidiary under this Agreement unless it is, or will concurrently
become, an "Unrestricted Subsidiary" as defined in, and for all purposes of, the
Senior Unsecured Debt Documents and (iv) no Unrestricted Subsidiary may be
designated as a Restricted Subsidiary under this Agreement unless it is, or will
concurrently become, a "Restricted Subsidiary" as defined in, and for all
purposes of, the Senior Unsecured Debt Documents. The designation of any
Restricted Subsidiary as an Unrestricted Subsidiary shall constitute an
investment by the Borrower therein at the date of designation in an amount equal
to the net book value of the Borrower's investment therein. The designation of
any Unrestricted Subsidiary as a Restricted Subsidiary shall constitute the
incurrence at the time of designation of any Debt or Liens of such Subsidiary
existing at such time.

of its Subsidiaries (other than any Unrestricted Subsidiary) to, comply with all

material adverse effect on the Borrower's ability to perform its obligations
under any Loan Document or impose any liability on any Lender.

     Section 5.18. Amendment of Material Documents. The Borrower will not, and
will not permit any of its Subsidiaries (other than, with respect to clause (b)

     material respects for five days after the earlier to occur of (i) the date
     on which an officer of the Borrower shall obtain knowledge thereof, or (ii)

          (n) any Lien purported to be created under any Security Document shall
     cease to be, or shall be asserted by the Borrower not to be, a valid and

     disposition of the applicable Collateral in a transaction permitted under
     the Loan Documents; or

     Receivables Financing entered into in accordance with this Agreement and on
     terms satisfactory to the Administrative Agent) shall have been terminated,
     whether voluntarily or otherwise; provided that any such termination of the
     Effective Date Receivables Financing (or any such replacement Receivables
     Financing) shall not constitute an Event of Default hereunder if (a) the

continuance of such event, the Administrative Agent may, and at the request of
the Required Lenders shall, by notice to the Borrower, take either or both of
the following actions, at the same or different times: (i) terminate the
Commitments, and thereupon the Commitments shall terminate immediately, and (ii)
declare the Loans then outstanding to

                                       92
<PAGE>

be due and payable in whole (or in part, in which case any principal not so
declared to be due and payable may thereafter be declared to be due and
payable), and thereupon the principal of the Loans so declared to be due and
payable, together with accrued interest thereon and all fees and other
obligations of the Borrower accrued hereunder, shall become due and payable
immediately, without presentment, demand, protest or other notice of any kind,
all of which are waived by the Borrower; and in the case of any event with
respect to the Borrower described in clause (h) or (i) above, the Commitments
shall automatically terminate and the principal of the Loans then outstanding,
together with accrued interest thereon and all fees and other obligations of the
Borrower accrued hereunder, shall automatically become due and payable, without
presentment, demand, protest or other notice of any kind, all of which are
waived by the Borrower. Additionally, and without limiting the generality of the

Collateral Account in accordance with Section 5(f) of the Security Agreement.

     Section 7.1. Appointment and Authorization. Each Lender Party irrevocably
appoints each Agent as its agent and authorizes each Agent to take such actions
as agent on its behalf and to exercise such powers as are delegated to the Agent
by the terms of the Loan Documents, together with such actions and powers as are
reasonably incidental thereto.

     Section 7.2. Rights and Powers as a Lender. Each Agent shall, in its
capacity as a Lender, have the same rights and powers as any other Lender and
may exercise or refrain from exercising the same as though it were not one of
the Agents. Each Agent and its Affiliates may accept deposits from, lend money
to and generally engage in any kind of business with the Borrower or any
Subsidiary or Affiliate of the Borrower as if it were not an Agent hereunder.

     Section 7.3. Limited Duties and Responsibilities . None of the Agents shall
have any duties or obligations except those expressly set forth in the Loan
Documents. Without limiting the generality of the foregoing, (a) none of the
Agents shall be subject to any fiduciary or other implied duties, regardless of
whether a Default has occurred and is continuing, (b) none of the Agents shall
have any duty to take any discretionary action or exercise any discretionary
powers, except discretionary rights and powers expressly contemplated by the
Loan Documents that such Agent is required in writing to exercise by the

                                       93
<PAGE>

Required Lenders (or such other number or percentage of the Lenders as shall be
necessary under the circumstances as provided in Section 9.02), and (c) except
as expressly set forth in the Loan Documents, none of the Agents shall have any
duty to disclose, or shall 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 Agent or any of its Affiliates in any
capacity. None of the Agents shall 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) or in the absence of its own gross
negligence or wilful misconduct. Each Agent shall be deemed not to have
knowledge of any Default unless and until written notice thereof is given to
such Agent by the Borrower or a Lender, and none of the Agents shall 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 Loan 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 Loan
Document, (iv) the validity, enforceability, effectiveness or genuineness of any
Loan Document or any other agreement, instrument or document, or (v) the
satisfaction of any condition set forth in Article 4 or elsewhere in any Loan
Document, other than to confirm receipt of items expressly required to be
delivered to such Agent.

     Section 7.4. Authority to Rely on Certain Writings, Statements and Advice.
Each 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. Each 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. Each Agent may consult
with legal counsel (who may be counsel for the Borrower), 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, accountants or experts.

     Section 7.5. Sub-Agents and Related Parties. Each Agent may perform any and
all its duties and exercise its rights and powers by or through one or more
sub-agents appointed by it. Each Agent and any such sub-agent may perform any
and all its duties and exercise its rights and powers through their respective
Related Parties. The exculpatory provisions of the preceding Sections of this
Article shall apply to any such sub-agent and to the Related Parties of each
Agent and any such sub-agent, and shall apply to activities in connection with
the syndication of the

                                       94

credit facilities provided for herein as well as activities as an Agent
hereunder.

     Section 7.6. Resignation; Successor Agents. Subject to the appointment and
acceptance of a successor Agent as provided in this Section, any Agent may
resign at any time (and, upon the request of the Required Lenders, JPMorgan
Chase Bank will so resign) by notifying the Lenders, the LC Issuing Bank and the
Borrower. Upon any such resignation, the Required Lenders shall have the right,
in consultation with the Borrower, to appoint a successor Agent; provided that
consultation with the Borrower shall not be required if an Event of Default
shall have occurred and be continuing. If no successor Agent shall have been so
appointed by the Required Lenders and shall have accepted such appointment
within 30 days after the retiring Agent gives notice of its resignation, then
the retiring Agent may, on behalf of the Lenders and the LC Issuing Bank,
appoint a successor Agent which shall be a bank or financial institution with an
office in New York, New York, or an Affiliate of any such bank or financial
institution. Upon acceptance of its appointment as Agent hereunder by a
successor Agent, such successor Agent shall succeed to and become vested with
all the rights, powers, privileges and duties of the retiring Agent, and the
retiring Agent shall be discharged from its duties and obligations hereunder.
The fees payable by the Borrower to a successor Agent shall be the same as those
payable to its predecessor unless otherwise agreed by the Borrower and such
successor Agent. After any retiring Agent's resignation hereunder as Agent, the
provisions of this Article and Section 9.03 shall continue in effect for the
benefit of such retiring 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 Agent was acting as an Agent hereunder.

     Section 7.7. Credit Decisions by Lenders. Each Lender acknowledges that it
has, independently and without reliance on any Agent or any other Lender Party
and based on such documents and information as it has deemed appropriate, made
its own credit analysis and decision to enter into this Agreement. Each Lender
also acknowledges that it will, independently and without reliance on any Agent
or any other Lender Party and based on such documents and information as it
shall from time to time deem appropriate, continue to make its own decisions in
taking or not taking action under or based on this Agreement, any other Loan
Document or related agreement or any document furnished hereunder or thereunder.

     Section 7.8. Agents' Fees. The Borrower shall pay to each Agent for its own
account fees in the amounts and at the times previously agreed upon by the
Borrower and such Agent.

Agreement.

     Section 8.2. Waivers; Amendments. (a) No failure or delay by any Lender
Party in exercising any right or power hereunder or under any other Loan
Document shall operate as a waiver thereof, nor shall any single or partial
exercise of any such right or power, or any abandonment or discontinuance of
steps to enforce such a right or power, preclude any other or further exercise
thereof or the exercise of any other right or power. The rights and remedies of
the Lender Parties under the Loan Documents are cumulative and are not exclusive
of any rights or remedies that they would otherwise have. No waiver of any
provision of any Loan Document or consent to any departure by the Borrower
therefrom shall in any event be effective unless the same shall be permitted by
subsection (b) of this Section, and then such waiver or consent shall be
effective only in the specific instance and for the purpose for which given.
Without limiting the generality of the foregoing, neither the making of a Loan
nor the issuance, amendment, renewal or extension of a Letter of Credit shall be
construed as a waiver of any Default, regardless of whether any Lender Party had
notice or knowledge of such Default at the time.

     (b) No Loan Document or provision thereof may be waived, amended or
modified except, in the case of this Agreement, by an agreement or agreements in
writing entered into by the Borrower and the Required Lenders or, in the case of
any other Loan Document, by an agreement or agreements in writing entered into
by the parties thereto with the consent of the Required Lenders; provided that
no such agreement shall:

          (i) increase the Commitment of any Lender without its written consent;

          (ii) reduce the principal amount of any Loan or LC Disbursement or
     reduce the rate of interest thereon, or reduce any fee payable hereunder,
     without the written consent of each Lender Party affected thereby;

          (iii) postpone the maturity of any Loan, or the required date of

                                       97
<PAGE>

     any mandatory payment of principal (including without limitation pursuant
     to Section 2.10(b), or the required date of reimbursement of any LC
     Disbursement, or any date for the payment of any interest or fee payable
     hereunder, or reduce the amount of, waive or excuse any such payment, or
     postpone the scheduled date of expiration of any Commitment, without the
     written consent of each Lender Party affected thereby;

          (iv) change Section 2.18(b) or 2.18(c) in a manner that would alter
     the pro rata sharing of payments required thereby, without the written
     consent of each Lender;

          (v) change any provision of this Section or the percentage set forth
     in the definition of "Required Lenders" or any other provision of any Loan
     Document specifying the number or percentage of Lenders required to take
     any action thereunder, without the written consent of each Lender;

          (vi) release all or any substantial portion of the Collateral from the
     Transaction Liens, without the written consent of each Lender (it being
     understood that, for purposes of this Section 9.02(b)(vi), a release of
     Collateral comprising 10% or more of the Borrowing Base in effect on the
     date of such release shall constitute release of a substantial portion of
     Collateral);

          (vii) reduce the amount of the Availability Block, without the written
     consent of each Lender;

          (viii) increase the Borrowing Base advance rates, eliminate or reduce
     Availability Reserves or otherwise cause the Borrowing Base to be
     increased, without the written consent of Lenders having aggregate
     Exposures and unused Commitments representing at least 85% of the sum of
     all Exposures and unused Commitments at such time;

          (ix) increase the aggregate amount of the Commitments by an amount in
     excess of the amount permitted pursuant to Section 2.20(c), or amend
     Section 2.20(c) to permit increases in the aggregate Commitments in excess
     of an aggregate amount equal to $150,000,000 during the term of this
     Agreement, without the written consent of Lenders having aggregate
     Exposures and unused Commitments representing at least 75% of the sum of
     all Exposures and unused Commitments at such time; or

          (x) unless signed by a Designated Lender or its Designating Lender,
     subject such Designated Lender to any additional obligation or affect its
     rights hereunder (unless the rights of all the Lenders are similarly
     affected); and

                                       98
<PAGE>

provided further that no such agreement shall amend, modify or otherwise affect
the rights or duties of any Agent, the LC Issuing Bank or the Swingline Lender
without its prior written consent; and provided further that neither a reduction
or termination of Commitments pursuant to Section 2.08 or 2.11, nor an increase
in Commitments pursuant to Section 2.20, constitutes an amendment, waiver or
modification for purposes of this Section 9.02.

     (c) Notwithstanding the foregoing, if the Required Lenders enter into or
consent to any waiver, amendment or modification pursuant to subsection (b) of
this Section, no consent of any other Lender will be required if, when such
waiver, amendment or modification becomes effective, (i) the Commitment of each
Lender not consenting thereto terminates and (ii) all amounts owing to it or
accrued for its account hereunder are paid in full.

     Section 8.3. Expenses; Indemnity; Damage Waiver. (a) The Borrower shall pay
(i) all reasonable and documented out-of-pocket expenses incurred by each Agent
and its Affiliates, including the reasonable fees, charges and disbursements of
Davis Polk & Wardwell, special counsel for the Administrative Agent, in
connection with the syndication of the credit facilities provided for herein,
the preparation and administration of the Loan Documents and any amendments,
modifications or waivers of the provisions thereof (whether or not the
transactions contemplated hereby or thereby shall be consummated), (ii) all
reasonable and documented out-of-pocket expenses incurred by the LC Issuing Bank
in connection with the issuance, amendment, renewal or extension of any Letter
of Credit or any demand for payment thereunder and (iii) all out-of-pocket
expenses incurred by any Lender Party, including the fees, charges and
disbursements of any counsel for any Lender Party, in connection with the
enforcement or protection of its rights in connection with the Loan Documents
(including its rights under this Section), the Letters of Credit or the Loans,
including all such out-of-pocket expenses incurred during any workout,
restructuring or negotiations in respect of the Letters of Credit or the Loans.

     (b) The Borrower shall indemnify each of the Lender Parties and their
respective Related Parties (each such Person being called an "Indemnitee")
against, and hold each Indemnitee harmless from, any and all losses, claims,
damages, liabilities and related expenses, including the fees, charges and
disbursements of counsel for any Indemnitee, incurred by or asserted against any
Indemnitee arising out of, in connection with, or as a result of (i) the
execution or delivery of any Loan Document or any other agreement or instrument
contemplated hereby, the performance by the parties to the Loan Documents of
their respective obligations thereunder or the consummation of the Financing
Transactions or any other transactions contemplated hereby, (ii) any Loan or
Letter of Credit or the use of the proceeds therefrom (including any refusal by
the

                                       99
<PAGE>

LC Issuing Bank to honor a demand for payment under a Letter of Credit if the
documents presented in connection with such demand do not comply with the terms
of such Letter of Credit), (iii) any actual or alleged presence or release of
Hazardous Materials on or from any property currently or formerly owned or
operated by the Borrower or any Subsidiary, or (iv) any actual or prospective
claim, litigation, investigation or proceeding relating to any of the foregoing,
whether based on contract, tort or any other theory and regardless of whether
any Indemnitee is a party thereto; provided that (i) such indemnity shall not be
available to any Indemnitee to the extent that such losses, claims, damages,
liabilities or related expenses are determined by a court of competent
jurisdiction by final and nonappealable judgment to have resulted from such
Indemnitee's gross negligence or wilful misconduct; (ii) such indemnity shall
not be available to any Indemnitee for losses, claims, damages, liabilities or
related expenses arising out of a proceeding in which such Indemnitee and the
Borrower are adverse parties to the extent that the Borrower prevails on the
merits, as determined by a court of competent jurisdiction (it being understood
that nothing in this Agreement shall preclude a claim or suit by the Borrower
against any Indemnitee for such Indemnitee's failure to perform any of its
obligations to the Borrower under the Loan Documents); (iii) the Borrower shall
not, in connection with any such proceeding or related proceedings in the same
jurisdiction and in the absence of conflicts of interest, be liable for the fees
and expenses of more than one law firm at any one time for the Indemnitees
(which law firm shall be selected (x) by mutual agreement of the Administrative
Agent and the Borrower or (y) if no such agreement has been reached following
the Administrative Agent's good faith consultation with the Borrower with
respect thereto, by the Administrative Agent in its sole discretion); (iv) each
Indemnitee shall give the Borrower (x) prompt notice of any such action brought
against such Indemnitee in connection with a claim for which it is entitled to
indemnity under this Section and (y) an opportunity to consult from time to time
with such Indemnitee regarding defensive measures and potential settlement; and
(v) the Borrower shall not be obligated to pay the amount of any settlement
entered into without its written consent (which consent shall not be
unreasonably withheld).

     (c) To the extent that the Borrower fails to pay any amount required to be
paid by it to any Agent, the LC Issuing Bank or the Swingline Lender under
subsection (a) or (b) of this Section, each Lender severally agrees to pay to
such Agent, the LC Issuing Bank or the Swingline Lender, as the case may be,
such Lender's pro rata share (determined as of the time that the applicable
unreimbursed expense or indemnity payment is sought) of such unpaid amount;
provided that the unreimbursed expense or indemnified loss, claim, damage,
liability or related expense, as the case may be, was incurred by or asserted
against such Agent, the LC Issuing Bank or the Swingline Lender in its capacity
as such. For purposes hereof, a Lender's "pro rata share" shall be determined
based on its share of the sum of the total Exposures and unused Commitments at
the time.

                                      100
<PAGE>

     (d) To the extent permitted by applicable law, the Borrower shall not
assert, and each hereby waives, any claim against any Indemnitee, on any theory
of liability, for special, indirect, consequential or punitive damages (as
opposed to direct or actual damages) arising out of, in connection with, or as a
result of, this Agreement or any agreement or instrument contemplated hereby,
the Financing Transactions, any Loan or Letter of Credit or the use of the
proceeds thereof.

     (e) All amounts due under this Section shall be payable within five
Business Days after written demand therefor.

     Section 8.4. Successors and Assigns. (a) The provisions of this Agreement
shall be binding on and inure to the benefit of the parties hereto and their
respective successors and assigns permitted hereby (including any Affiliate of
the LC Issuing Bank that issues any Letter of Credit), except that the Borrower
may not assign or otherwise transfer any of its rights or obligations hereunder
without the prior written consent of each Lender (and any attempted assignment
or transfer by the Borrower without such consent shall be null and void).
Nothing in this Agreement, expressed or implied, shall be construed to confer
upon any Person (except the parties hereto, their respective successors and
assigns permitted hereby (including any Affiliate of the LC Issuing Bank that
issues any Letter of Credit) and, to the extent expressly provided herein, the
Related Parties of the Lender Parties) any legal or equitable right, remedy or
claim under or by reason of this Agreement.

     (b) Any Lender may assign to one or more assignees all or a portion of its
rights and obligations under this Agreement (including all or a portion of any
Commitment it has at the time and any Loans at the time owing to it); provided
that:

          (i) except in the case of an assignment to a Lender or a Lender
     Affiliate, each of the Borrower and the Administrative Agent (and, in the
     case of an assignment of all or a portion of a Commitment or any Lender's
     obligations in respect of its LC Exposure or Swingline Exposure, the LC
     Issuing Bank and the Swingline Lender) must give their prior written
     consent to such assignment (which consents shall not be unreasonably
     withheld);

          (ii) each partial assignment shall be made as an assignment of a
     proportionate part of all the assigning Lender's rights and obligations
     under this Agreement;

          (iii) unless each of the Borrower and the Administrative Agent
     otherwise consent, the amount of the Commitment or Loans of the assigning
     Lender subject to each such assignment (determined as of the date on which
     the relevant Assignment is delivered to the Administrative

                                      101
<PAGE>

     Agent) shall not be less than $5,000,000; provided that this clause (iii)
     shall not apply to an assignment to a Lender or a Lender Affiliate or an
     assignment of the entire remaining amount of the assigning Lender's
     Commitment or Loans;

          (iv) the parties to each assignment shall execute and deliver to the
     Administrative Agent an Assignment, together with a processing and
     recordation fee of $3,500; provided that only one such fee shall be due in
     respect of a simultaneous assignment to more than one Lender Affiliate; and

          (v) the assignee, if it shall not be a Lender, shall deliver to the
     Administrative Agent a completed Administrative Questionnaire;

and provided further that any consent of the Borrower otherwise required under
this subsection shall not be required if an Event of Default has occurred and is
continuing. Subject to acceptance and recording thereof pursuant to subsection
(d) of this Section, from and after the effective date specified in each
Assignment the assignee thereunder shall be a party hereto and, to the extent of
the interest assigned by such Assignment, have the rights and obligations of a
Lender under this Agreement, and the assigning Lender thereunder shall, to the
extent of the interest assigned by such Assignment, be released from its
obligations under this Agreement (and, in the case of an Assignment covering all
of the assigning Lender's rights and obligations under this Agreement, such
Lender shall cease to be a party hereto but shall continue to be entitled to the
benefits of Sections 2.15, 2.16, 2.17 and 9.03). Any assignment or transfer by a
Lender of rights or obligations under this Agreement that does not comply with
this subsection shall be treated for purposes of this Agreement as a sale by
such Lender of a participation in such rights and obligations in accordance with
subsection (e) of this Section.

     (c) The Administrative Agent, acting for this purpose as an agent of the
Borrower, shall maintain at one of its offices in New York City a copy of each
Assignment delivered to it and a register for the recordation of the names and
addresses of the Lenders, their respective Commitments and the principal amounts
of the Loans and LC Disbursements owing to each Lender pursuant to the terms
hereof from time to time (the "Register"). The entries in the Register shall be
conclusive (absent manifest error), and the parties hereto may treat each Person
whose name is recorded in the Register pursuant to the terms hereof as a Lender
for all purposes of this Agreement, notwithstanding notice to the contrary. The
Register shall be available for inspection by any party hereto at any reasonable
time and from time to time upon reasonable prior notice.

     (d) Upon its receipt of a duly completed Assignment executed by an

                                      102
<PAGE>

assigning Lender and an assignee, the assignee's completed Administrative
Questionnaire (unless the assignee shall already be a Lender hereunder), the
processing and recordation fee referred to in subsection (b) of this Section and
any written consent to such assignment required by subsection (b) of this
Section, the Administrative Agent shall accept such Assignment and record the
information contained therein in the Register. No assignment shall be effective
for purposes of this Agreement unless it has been recorded in the Register as
provided in this subsection.

     (e) Any Lender may, without the consent of the Borrower or any other Lender
Party, sell participations to one or more banks or other entities
("Participants") in all or a portion of such Lender's rights and obligations
under this Agreement (including all or a portion of its Commitments and the
Loans owing to it); provided that (i) such Lender's obligations under this
Agreement shall remain unchanged, (ii) such Lender shall remain solely
responsible to the other parties hereto for the performance of such obligations
and (iii) the Borrower and the other Lender Parties shall continue to deal
solely and directly with such Lender in connection with such Lender's rights and
obligations under this Agreement. Any agreement or instrument pursuant to which
a Lender sells such a participation shall provide that such Lender shall retain
the sole right to enforce the Loan Documents and to approve any amendment,
modification or waiver of any provision of the Loan Documents; provided that
such agreement or instrument may provide that such Lender will not, without the
consent of the Participant, agree to any amendment, modification or waiver
described in clause (i), (ii), (iii) or (vii) of the first proviso to Section
9.02(b) that affects such Participant. Subject to subsection (f) of this
Section, each Participant shall be entitled to the benefits of Sections 2.15,
2.16 and 2.17 to the same extent as if it were a Lender and had acquired its
interest by assignment pursuant to subsection (b) of this Section. To the extent
permitted by law, each Participant also shall be entitled to the benefits of
Section 9.09 as though it were a Lender, provided that such Participant agrees
to be subject to Section 2.18(c) as though it were a Lender.

     (f) A Participant shall not be entitled to receive any greater payment
under Section 2.15 or 2.17 than the applicable Lender would have been entitled
to receive with respect to the participation sold to such Participant, unless
the sale of the participation to such Participant is made with the Borrower's
prior written consent. A Participant that would be a Foreign Lender if it were a
Lender shall not be entitled to the benefits of Section 2.17 unless the Borrower
is notified of the participation sold to such Participant and such Participant
agrees, for the benefit of the Borrower, to comply with Section 2.17(e) as
though it were a Lender.

     (g) Any Lender may at any time pledge or assign a security interest in all
or any portion of its rights under this Agreement to secure obligations of such
Lender, including any pledge or assignment to secure obligations to a Federal

                                      103
<PAGE>

Reserve Bank, and this Section shall not apply to any such pledge or assignment
of a security interest; provided that no such pledge or assignment of a security
interest shall release a Lender from any of its obligations hereunder or
substitute any such pledgee or assignee for such Lender as a party hereto.

     Section 8.5. Designated Lenders. (a) Subject to the provisions of this
Section 9.05(a), any Lender may from time to time elect to designate an Eligible
Designee to provide all or a portion of the Loans to be made by such Lender
pursuant to this Agreement; provided that such designation shall not be
effective unless the Borrower and the Administrative Agent consent thereto. When
a Lender and its Eligible Designee shall have signed an agreement substantially
in the form of Exhibit H hereto (a "Designation Agreement") and the Borrower and
the Administrative Agent shall have signed their respective consents thereto,
such Eligible Designee shall become a Designated Lender for purposes of this
Agreement. The Designating Lender shall thereafter have the right to permit such
Designated Lender to provide all or a portion of the loans to be made by such
Designating Lender pursuant to Section 2.01 and the making of such Loans or
portions thereof shall satisfy the obligation of the Designating Lender to the
same extent, and as if, such Loans or portion thereof were made by the
Designating Lender. As to any Loans or portion thereof made by it, each
Designated Lender shall have all the rights that a Lender making such Loans or
portion thereof would have had under this Agreement and otherwise; provided that
(x) its voting rights under this Agreement shall be exercised solely by its
Designating Lender and (y) its Designating Lender shall remain solely
responsible to the other parties hereto for the performance of its obligations
under this Agreement, including its obligations in respect of the Loans or
portion thereof made by it. No additional promissory note shall be required to
evidence Loans or portions thereof made by a Designated Lender; and the
Designating Lender shall be deemed to hold any promissory note issued pursuant
to Section 2.09(e) as agent for its Designated Lender to the extent of the Loans
or portion thereof funded by such Designated Lender. Each Designating Lender
shall act as administrative agent for its Designated Lender and give and receive
notices and other communications on its behalf. Any payments for the account of
any Designated Lender shall be paid to its Designating Lender as administrative
agent for such Designated Lender and neither the Borrower nor the Administrative
Agent shall be responsible for any Designating Lender's application of such
payments. In addition, any Designated Lender may (i) with notice to, but without
the prior written consent of, the Borrower or the Administrative Agent, assign
all or portions of its interest in any Loans to its Designating Lender or to any
financial institutions consented to by the Borrower and the Administrative Agent
providing liquidity and/or credit facilities to or for the account of such
Designated Lender to support the funding of Loans or portions thereof made by
such Designated Lender and (ii) disclose on a

                                      104
<PAGE>

confidential basis any non-public information relating to its Loans or portions
thereof to any rating agency, commercial paper dealer or provider of any
guarantee, surety, credit or liquidity enhancement to such Designated Lender.

     (b) Each party to this Agreement agrees that it will not institute against,
or join any other Person in instituting against, any Designated Lender any
bankruptcy, reorganization, arrangement, insolvency or liquidation proceeding or
other proceeding under any federal or state bankruptcy or similar law, for one
year and a day after all outstanding senior indebtedness of such Designated
Lender is paid in full. The Designating Lender for each Designated Lender agrees
to indemnify, save, and hold harmless each other party hereto for any loss,
cost, damage and expense arising out of its inability to institute any such
proceeding against such Designated Lender. This Section 9.05(b) shall survive
the termination of this Agreement.

     Section 8.6. Survival. All covenants, agreements, representations and
warranties made by the Borrower in the Loan Documents and in certificates or
other instruments delivered in connection with or pursuant to the Loan Documents
shall be considered to have been relied upon by the other parties hereto and
shall survive the execution and delivery of the Loan Documents and the making of
any Loans and issuance of any Letters of Credit, regardless of any investigation
made by any such other party or on its behalf and notwithstanding that any
Lender Party may have had notice or knowledge of any Default or incorrect
representation or warranty at the time any credit is extended hereunder, and
shall continue in full force and effect as long as any principal of or accrued
interest on any Loan or any fee or other amount payable hereunder is outstanding
and unpaid or any Letter of Credit is outstanding or any Commitment has not
expired or terminated. The provisions of Sections 2.15, 2.16, 2.17 and 9.03 and
Article 8 shall survive and remain in full force and effect regardless of the
consummation of the Financing Transactions, the repayment of the Loans, the
expiration or termination of the Letters of Credit and the Commitments or the
termination of this Agreement or any provision hereof.

     Section 8.7. Counterparts; Integration; Effectiveness. This Agreement may
be executed in counterparts (and by different parties hereto on different
counterparts), each of which shall constitute an original, but all of which when
taken together shall constitute a single contract. This Agreement, the other
Loan Documents and any separate letter agreements with respect to fees payable
to the Administrative Agent constitute the entire contract among the parties
relating to the subject matter hereof and supersede any and all previous
agreements and understandings, oral or written, relating to the subject matter
hereof. Except as provided in Section 4.01, this Agreement (i) will become

                                      105
<PAGE>

effective when the Administrative Agent shall have signed this Agreement and
received counterparts hereof that, when taken together, bear the signatures of
each of the other parties hereto and (ii) thereafter will be binding upon and
inure to the benefit of the parties hereto and their respective successors and
assigns. Delivery of an executed counterpart of a signature page of this
Agreement by telecopy will be effective as delivery of a manually executed
counterpart of this Agreement.

     Section 8.8. Severability. If any provision of any Loan Document is
invalid, illegal or unenforceable in any jurisdiction then, to the fullest
extent permitted by law, (i) such provision shall, as to such jurisdiction, be
ineffective to the extent (but only to the extent) of such invalidity,
illegality or unenforceability, (ii) the other provisions of the Loan Documents
shall remain in full force and effect in such jurisdiction and shall be
liberally construed in favor of the Lender Parties in order to carry out the
intentions of the parties thereto as nearly as may be possible and (iii) the
invalidity, illegality or unenforceability of any such provision in any
jurisdiction shall not affect the validity, legality or enforceability of such
provision in any other jurisdiction.

     Section 8.9. Right of Setoff. If an Event of Default shall have occurred
and be continuing, each Lender and each of its Affiliates is authorized at any
time and from time to time, to the fullest extent permitted by law, to set off
and apply any and all deposits (general or special, time or demand, provisional
or final) at any time held and other obligations at any time owing by such
Lender or Affiliate to or for the credit or the account of the Borrower against
any obligations of the Borrower now or hereafter existing hereunder and held by
such Lender, irrespective of whether or not such Lender shall have made any
demand hereunder and although such obligations may be unmatured. The rights of
each Lender under this Section are in addition to other rights and remedies
(including other rights of setoff) that such Lender may have.

     Section 8.10. Governing Law; Jurisdiction; Consent to Service of Process.
(a) This Agreement shall be construed in accordance with and governed by the law
of the State of New York.

     (b) The Borrower irrevocably and unconditionally submits, for itself and
its property, to the nonexclusive jurisdiction of the Supreme Court of the State
of New York sitting in New York County and of the United States District Court
of the Southern District of New York, and any relevant appellate court, in any
action or proceeding arising out of or relating to any Loan Document, or for
recognition or enforcement of any judgment, and each party hereto irrevocably
and unconditionally agrees that all claims in respect of any such action or
proceeding may be heard and determined in such New York State court or, to the
extent permitted by law, in such Federal court. Each party hereto agrees that a
final

                                      106
<PAGE>

judgment in any such action or proceeding shall be conclusive and may be
enforced in other jurisdictions by suit on the judgment or in any other manner
provided by law. Nothing in any Loan Document shall affect any right that any
Lender Party may otherwise have to bring any action or proceeding relating to
any Loan Document against the Borrower or its properties in the courts of any
jurisdiction.

     (c) The Borrower irrevocably and unconditionally waives, to the fullest
extent it may legally and effectively do so, any objection that it may now or
hereafter have to the laying of venue of any suit, action or proceeding arising
out of or relating to any Loan Document in any court referred to in subsection
(b) of this Section. Each party hereto irrevocably waives, to the fullest extent
permitted by law, the defense of an inconvenient forum to the maintenance of any
such suit, action or proceeding in any such court.

     (d) Each party hereto irrevocably consents to service of process in the
manner provided for notices in Section 9.01. Nothing in any Loan Document will
affect the right of any party hereto to serve process in any other manner
permitted by law.

     Section 8.11. WAIVER OF JURY TRIAL. EACH PARTY HERETO WAIVES, TO THE
FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL BY
JURY IN ANY LEGAL PROCEEDING DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING
TO ANY LOAN DOCUMENT OR ANY TRANSACTION CONTEMPLATED THEREBY (WHETHER BASED ON
CONTRACT, TORT OR ANY OTHER THEORY). EACH PARTY HERETO (A) CERTIFIES THAT NO
REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY
OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK
TO ENFORCE THE FOREGOING WAIVER AND (B) ACKNOWLEDGES THAT IT AND THE OTHER
PARTIES HERETO HAVE BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER
THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION.

     Section 8.12. Headings. Article and Section headings and the Table of
Contents herein are for convenience of reference only, are not part of this
Agreement and shall not affect the construction of, or be taken into
consideration in interpreting, this Agreement.

     Section 8.13. Confidentiality. Each Lender Party agrees to maintain the
confidentiality of the Information (as defined below), except that Information
may be disclosed (a) to its and its Affiliates' directors, officers, employees
and agents, including accountants, legal counsel and other advisors (it being
understood that the Persons to whom such

                                      107
<PAGE>

disclosure is made will be informed of the confidential nature of such
Information and instructed to keep such Information confidential), (b) to the
extent requested by any regulatory authority, (c) to the extent required by
applicable laws or regulations or by any subpoena or similar legal process, (d)
to any other party to this Agreement, (e) in connection with the exercise of any
remedy hereunder or any suit, action or proceeding relating to any Loan Document
or the enforcement of any right thereunder, (f) subject to an agreement
containing provisions substantially the same as those of this Section, to (i)
any actual or prospective assignee of or Participant in any of its rights or
obligations under this Agreement or (ii) any actual or prospective counterparty
(or its advisors) to any swap or derivative transaction relating to the Borrower
and its obligations, (g) with the consent of the Borrower or (h) to the extent
such Information either (i) becomes publicly available other than as a result of
a breach of this Section or (ii) becomes available to any Lender Party on a
nonconfidential basis from a source other than the Borrower. For the purposes of
this Section, "Information" means all information received from the Borrower
relating to the Borrower or its business, other than any such information that
is available to any Lender Party on a nonconfidential basis before disclosure by
the Borrower; provided that, in the case of information received from the
Borrower after the date hereof, such information is clearly identified at the
time of delivery as confidential.

     Section 8.14. Interest Rate Limitation. Notwithstanding anything herein to
the contrary, if at any time the interest rate applicable to any Loan, together
with all fees, charges and other amounts that are treated as interest on such
Loan under applicable law (collectively the "Charges"), shall exceed the maximum
lawful rate (the "Maximum Rate") that may be contracted for, charged or
otherwise received by the Lender holding such Loan in accordance with applicable
law, the rate of interest payable in respect of such Loan hereunder, together
with all Charges payable in respect thereof, shall be limited to the Maximum
Rate and, to the extent lawful, the interest and Charges that would have been
payable in respect of such Loan but were not payable as a result of the
operation of this Section shall be cumulated and the interest and Charges
payable to such Lender in respect of other Loans or periods shall be increased
(but not above the Maximum Rate therefor) until such Lender shall have received
such cumulated amount, together with interest thereon at the Federal Funds
Effective Rate to the date of payment.

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

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

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

enforcement of the Transaction Liens pursuant to the UCC.

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

that the Collateral Agent may reasonably request, in order to:

          (i) create, preserve, perfect, confirm or validate the Transaction

obtain the full benefits of the Security Documents; or

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

recording or filing of any financing or continuation statements or other
documents recorded or filed pursuant hereto.

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)
<PAGE>

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

request to evidence the fact that any asset so sold or disposed of is no longer
subject to a Transaction Lien.

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.

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

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
<PAGE>

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
<PAGE>

     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
<PAGE>

          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
<PAGE>

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
<PAGE>

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
the Credit Agreement and this Agreement).

          (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
pursuant to Section 12(b) stating that any Pledged Receivables qualify as
Transferred Receivables, the Collateral Agent and any third party shall be fully
protected in relying on such certificate as conclusive proof that the Related
Transferred Rights are not Collateral.

          (d) At any time before the Transaction Liens terminate, the Collateral
Agent may, at the written request of the Lien Grantor, (i) release any
Collateral (but not all or any substantial portion of the Collateral) with the
prior written consent of the Required Lenders or (ii) release any substantial
portion of the Collateral with the prior written consent of all the Lenders. For
purposes hereof, a release of Collateral comprising 10% or more of the Borrowing
Base in effect on the date of such release shall constitute release of a
substantial portion of the Collateral.
<PAGE>

          (e) Upon any termination of a Transaction Lien or release of
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.

          . Except in the case of notices and other communications expressly
permitted to be given by telephone, each notice, request or other communication
given to any party hereunder shall be in writing delivered by hand or overnight
courier service, mailed by certified or registered mail or sent by telecopy (or,
in the case of any notice to a Secured Party pursuant to Section 11(b) or
Section 11(h), transmitted by e-mail), as follows:
